Opis:
In connection with previously revealed disagreement of theoretically calculated and measured orthopositronium decay rate in vacuum we suggest the experiment to clarify which of the positronium annihilation amplitudes R$\text{}_{m}$,m = 0,±1 causes this disagreement. The developed for this purpose experimental procedure can also be used as the basis for the new area of positron spectroscopy, connected with the investigation of the anisotropic (spin dependent) interaction of positronium in the media.

Opis:
A survey is made on positronium dynamics in liquids. From literature data, it is shown that applying conventional kinetics to positronium reactions leads to quite satisfactory results in a large variety of solvents, solutes, reaction types and temperatures. On the opposite, applying the theoretically well established concepts of positronium bubble state and time-dependent reaction rate coefficient would imply the use of unrealistic solute radii in the related kinetic equations, with possible exception of large solutes (micelles). Some solutes displaying unexpectedly high reaction rate constants are shown to be refractory to any of the above quantitative approaches. The particular case of reversible positronium bound-state formation is further examined, the most consistent results arising, again, from the conventional analysis of the data.

Opis:
The potato (Solanum tuberosum L.) is one of the four major crops in Poland. In 2013 the area used for potato cultivation in Poland reached 270 thousand hectares. Among the important factors influencing the potato yield and quality are: soil cultivation and protection of plants. One of the most essential factors affecting the potato yield and quality is fertilization. The aim of the field trials carried out in 2014 on experimental potato plots was to determine the effect of dr Green foliar feed nutrients on plant health and on potato quality and yield (Jelly variety). The results of the studies and observations revealed that the application of Dr Green Ziemniak, Dr Green Start and Dr Green Energy foliar feeds favourably affected the quality, yield and structure of Jelly potato tuber crop.
Ziemniak (Solanum tuberosum L.) jest jedną z czterech najpopularniejszych roślin uprawnych w Polsce. Wielkość produkcji ziemniaka w 2013 roku w kraju wynosiła ponad 270 tysięcy hektarów. Istotnymi czynnikami kształtującymi wielkość i jakość plonów ziemniaka są między innymi uprawa roli i ochrona plantacji. Jednakże do najważniejszych czynników mających podstawowe znaczenie w kształtowaniu ilości i jakości uzyskiwanego plonu ziemniaka jest nawożenie. Celem przeprowadzonych w 2014 roku doświadczeń mikropoletkowych było określenie wpływu nawożenia dolistnego technologią Dr Green na zdrowotność roślin oraz na jakość i wielkość plonu ziemniaka odmiany Jelly. Uzyskane wyniki badań i przeprowadzonych obserwacji wykazały, że dolistna aplikacja nawozami Dr Green Ziemniak, Dr Green Start oraz Dr Green Energy korzystnie wpłynęła na jakość, wielkość i strukturę plonu bulw badanej odmiany ziemniaka.

Parrhesia
Opis:
An honest intellectual dutifully standing with truth against lies and treacheries of his society is a parrhesiastic figure in Foucault’s terminology. Foucault takes parrhesia as the fearless and frank speech regarding the truth of something or a situation before truth-mongering and public deception and he takes the parrhesiastic as the spokesperson for truth. In this light, Dr. Stockmann in Ibsen’s An Enemy of the People occupies a unique position within Ibsen’s political philosophy. Dutifully criticizing what the majority blindly take for granted from their liar leaders in the name of democracy, Dr. Stockmann fulfills the role of a parrhesiastic figure that stands against socio-political corruption. He enters a parrhesiastic game with both the majority and the officialdom to fulfill his democratic parrhesia as a truthful citizen before the duped community, while covertly preparing for his own philosophic parrhesia or self-care within the conformist community. However, his final failure lies in his confrontation with democracy itself, which wrongly gives the right of speaking even to the liars. This article thus aims at analyzing Ibsen’s play through a Foucauldian perspective regarding the concept of parrhesia and its relation to democracy. It is to reveal Ibsen’s satire on the fake ideology of democracy and highlight the necessity of humanity’s parrhesiastic self-care for the well-being of the self and the others.

Developments of three new time-resolved vibrational spectroscopies and their applications to electronically excited states are reviewed. Transformlimited picosecond time-resolved Raman spectroscopy has been used to study the vibrational dynamics of trans-stilbene in the lowest excited singlet state. Picosecond time-frequency two-dimensional multiplex Coherent Antistokes Raman Scattering spectroscopy has been used to probe the structure of diphenylacetylene in the lowest and the second lowest excited singlet states. Nanosecond time-resolved dispersive infrared spectroscopy has detected the singlet and triplet intramolecular charge transfer states of 4-(di-methylamino)benzonitrile. Strong evidence for a charge transfer structure has been obtained.

Opis:
This paper represents a fragment of systematic studies on positron annihilation in solid saturated hydrocarbons (alkanes, paraffins) from C$\text{}_{17}$H$\text{}_{36}$ to C$\text{}_{30}$H$\text{}_{62}$. The Tao-Eldrup model and its extensions allow to identify the places in the crystalline structure where positronium is trapped, and estimate respective trap sizes. In the rigid phase I positronium locates mainly in two-dimensional empty spaces between the lamellae of crystal structure. Additional free volumes exist in high temperature phases due to appearance of n-alkane conformers representing a non-planar molecule distortion. The rise of ortho-positronium intensity with the sample irradiation dose, which was seen earlier in polymers, is observed also in n-alkanes. One can find similarities between the ortho-positronium annihilation in crystalline alkanes and polymers, like exponential character of that rise, and the trap bleaching by illumination. It confirms the same origin of the intensity growth, i.e. the accumulation of trapped electrons. Two kinds of electron traps were found. The time constant of electron accumulation in the traps depends on the carbon chain length and varies with temperature in different way for even- and odd-numbered alkanes.

Opis:
Positron lifetime spectra in poly[1-(trimethylsilyl)]propine membranes were collected at different temperatures and various number of accumulated counts, in order to compare the results from analyses obtained by different decay models: discrete (that is, purely exponential) or continuous (with at least one distribution of lifetimes). Analysis into four discrete components is inadequate, unless a low number of counts (1 to 2 millions) is accumulated. Conversely, deconvolutions which allow the ortho-positronium lifetime to be distributed give satisfactory fits, even at the highest statistics (60 millions). An equivalent good fit in terms of χ$\text{}^{2}$ test is obtained with a five discrete components analysis, from which it is possible to extract information on the first moments (centroid and standard deviation) of ortho -positronium lifetime distribution.

Opis:
This paper reports on the results of positron annihilation lifetime measurements of three organic liquids: benzene (C₆H₆), cyclohexane (C₆H₁₂), and methanol (CH₃OH). The lifetime spectra are acquired at different temperatures for non-degassed, degassed, and oxygen-saturated samples, at temperatures between 5°C and 25°C. The spectra are analyzed using a standard three-exponential model. The influence of oxygen on each lifetime and intensity component is discussed.

Opis:
Positronium formation in Au films was studied using a magnetically guided continuous slow positron beam with variable energy. Black Au film with porous morphology was compared with conventional smooth Au film. In the smooth Au film positronium is formed on the film surface only. The black Au film exhibits porous sub-surface region containing micro-cavities interconnected with surface. Positronium is formed on inner surfaces of micro-cavities in the sub-surface region and travels through interconnected cavities towards the surface. 3-γ annihilation of ortho-positronium leaves a clear signature in two-dimensional coincidence Doppler broadening spectra. Measures of 3-γ annihilation contribution calculated from single γ-ray and coincidence Doppler broadening spectra were calculated and compared.

Opis:
Schwinger's variational principle is used to evaluate excitation cross-sections of hydrogen atom by proton impact in a range of energies excluding a pertubative treatment. To describe the strong coupling between the excitation and the capture channels that exists at low energies, the continuum states have been introduced in the total wave function. Our results show that these states can describe properly the projectile capture states.

Opis:
Scattering experiments are indispensable for the study of classical and quantum systems. In the Heidelberg approach, universal features are addressed by assuming that the reaction zone is fully quantum chaotic. Although it stems from nuclear physics, it later on turned out to be applicable to a large variety of systems on different scales, including classical wave systems. For a long time, the distribution of the off-diagonal scattering-matrix elements resisted analytical treatment. I review two recent studies in which my collaborators and I fully solved this problem. We also carried out a comparison with data from microwave experiments.

Opis:
Positronium (Ps) formation by weakly localized long-lived electrons (trapped electrons or anions) and positrons at low temperatures successfully explained the Ps formation enhancement at low temperatures observed in polymers and molecular solids. This Ps formation process is different from Ore process and spur process. The phenomena expected by this Ps formation mechanism, such as an effect due to visible light exposure, a density dependence of weakly localized electrons and the delayed Ps formation were successfully observed as the experimental evidence of this Ps formation process. Some possibilities for application of this new Ps formation were also given. One is a new idea for estimation of spin polarity of positrons. Another is the possibility of application to study the local molecular motion by observing the decay of Ps formation intensity.

Opis:
Mathematical model of formation of radiolytic products (e$\text{}_{aq}^{-}$, H, OH, H$\text{}_{2}$, H$\text{}_{3}$O$\text{}^{+}$, OH$\text{}^{-}$, Ps) in water is developed. It takes into account (1) reactions between dissolved scavengers of thermalized and hydrated electrons as well as epithermal ones; (2) ambipolar diffusion expansion of the intratrack species; (3) additional channels of Ps and H$\text{}_{2}$ formation due to appearance of weakly trapped electrons. Good agreement is obtained with experimental data on kinetics of accumulation of the products in pure water and their concentration variations in aqueous solutions.

Opis:
Coincidence Doppler broadening spectroscopy was applied to study n-hexane (C$\text{}_{6}$H$\text{}_{14}$), cyclohexane (C$\text{}_{6}$H$\text{}_{12}$) and cyclohexanone (C$\text{}_{6}$H$\text{}_{10}$O), at solid, as well as liquid states. The experiments were performed in parallel with traditional positron annihilation lifetime spectroscopy. Significant positron trapping by oxygen was observed in cyclohexanone; the oxygen effect is stronger in liquid state than in solid one, which can possibly be attributed to positron solvation in polar solution. Coincidence Doppler broadening results for n-hexane and cyclohexane indicate an existence of higher energetic annihilation electrons in Ps-bubble forming liquids than that in solids.

Opis:
In this study we have investigated thermomechanical and solid particle erosion behaviour of ABS/PA6 composites reinforced with CaCO₃ particles and SGF. ABS/PA6 composites were reinforced with CaCO₃ particles and SGF at different weight ratios (0, 10, 30, 15/15 wt.%). Composite materials were manufactured by twin screw extruder and injection molding machine. Thermomechanical properties were investigated by dynamic mechanical analysis (DMA) method. Moreover erosion wear behaviour was investigated on solid particle erosion test machine. Experimental results show that thermomechanical properties significantly depend on particle types and weight ratios. While storage modulus was found to be maximum for 30 wt.% SGF-reinforced samples, the loss modulus was found to be maximum for 15/15 wt.% hybrid samples. Moreover minimum loss factor values were found for hybrid samples, but glass transition temperature of samples were not effected significantly with CaCO₃ and SGF reinforcement. Erosion behaviour depends on particle impact angle, the type of reinforcing particles and their weight ratios. Maximum erosion rates were found at impingement angle of 30° for 30 wt.% CaCO₃-filled samples. According to experimental results both CaCO₃ and SGF reinforcement have positive influence on thermomechanical properties. However CaCO₃ and SGF reinforcement have reduced the solid particle erosion resistance of ABS/PA6 composites.

Opis:
In the present study, the production of Fe-Ti-B based alloys was realized and their structure and properties were investigated. Mechanical alloying proceeds by the continual cold welding and fracturing of the constituent mixture of Ti+4B+5Fe powder when subjected to the large compressive forces of a high speed mill. The powder charge together with 7 mm diameter steel balls were loaded into a tool steel grinding container at approximately 350 RPM for 20 h. The samples were shaped as cylinder of Ø15×8 mm dimensions by uniaxial pressing at 450 MPa. Then, the green body materials were produced by sintering at 1100°C for 1-4 h in argon atmosphere. The morphology of composite materials was investigated by optical microscopy and scanning electron microscopy and phase analysis was realized by x-ray diffraction analysis. The bulk densities of the materials were measured using by Archimedes method. Also, the micro-hardness of the samples was measured by Vickers indentation technique. As a result, Fe, iron boride (FeB, Fe₂B) and titanium boride (TiB₂) phases were detected in the phase analysis of the Fe-Ti-B based materials. The hardness of the materials was measured between 1107 $HV_{0.05}$ and 1551 $HV_{0.05}$, depending on sintering time. The densities of the samples were determined between 4.205 g/cm³ and 4.219 g/cm³.

A modified adiabatic approximation, with the positron treated as a light nucleus and its charge included only partially in the electronic Hamiltonian, was applied to compute the energies and properties of bound states of lithium positride, positronic beryllium and positronic magnesium. The electronic Schrödinger equation was solved with the configuration interaction method. No bound state was obtained for lithium positride, while the dissociation energies of positronic beryllium and positronic magnesium were underestimated by 2.6 and 7 millihartrees, respectively. Consequences for the applicability of the adiabatic approximation to describe positronic systems are discussed.

Artykuł przedstawia analizę okoliczności powstania urzędu Generalnego Delegata Rządu dla Galicji (1919-1921), jego ustrojową pozycję oraz zakres podjętych  zadań  w pierwszych miesiącach jego działalności. Dzieje tej rządowo-administracyjnej instytucji należą do mniej znanych w porównaniu z wiedzą na temat innych struktur administracji publicznej w początkach polskiej państwowości. Podstawą źródłową rozprawy stanowią lwowskie  i krakowskie materiały  archiwalne. Czynności urzędowe generalnego delegata  wiosną  1919 r. zostały odtworzone na podstawie pierwszego dla rządu  raportu z jego  działalności, które uzupełnione zostały wydawanymi przez delegata okólnikami dla podległych mu urzędów. Dały one obraz zarówno prawno-ustrojowej pozycji generalnego delegata, jak i udokumentowały sposób wykonywania powierzonych mu obowiązków w dziedzinie  utrzymania porządku i bezpieczeństwa, które pokrywały się z kompetencjami namiestnika Galicji w czasach austriackich. W artykule znalazło się także omówienie  stanowiska  Generalnego Delegata K. Gałeckiego w sporze o model administracyjnego ustroju na ziemiach  dawnego Królestwa Galicji i Lodomerii.   
The article presents an analysis of the circumstances surrounding creation of the office of the General Delegate of the Government for Galicia (1919—1921), its position in the political system, and the range of tasks undertaken in the first months of its activity. The his- tory of this governmental-administrative institution is not as well-known as that of other public administration structures from the beginning of Polish statehood. The sources for this study are archival materials from Lviv and Cracow. The administrative activities of the General Delegate in the spring of 1919 were reconstructed on the basis of the first report on his activities to the government, and supplemented with circulars issued by the Delegate for his subordinate offices. They provided a picture of both legal and organisational position of the General Delegate and documented the manner in which this institution carried out the duties entrusted to it regarding preservation of order and security, which corresponded to the competences of the Governor of Galicia in Austrian times. The article also includes a discussion about the stance of General Del- egate K. Galecki in the dispute over the model of administrative system in the lands of the former Kingdom of Galicia and Lodomeria.

Elastic collision between two H-like atoms using the ab initio static-exchange model (SEM) and a modified static-exchange model (MSEM) at cold energies are investigated in the center of mass frame considering the system as a four-body Coulomb problem where all the Coulomb interaction terms in the direct and exchange channels are treated exactly. The importance of an exact calculation to find basic physics is highlighted. In addition, the dependence of scattering length on the van der Waals interaction between the atoms and the dependence of scattering length on reduced-mass of the system are derived which is completely new information in the field of science.

Opis:
The positronium atom (Ps) is widely used as a probe to characterize nanoporous and mesoporous materials. Existing theoretical models for describing Ps annihilation rates by pick-off processes generally treat Ps as a point particle confined in a potential well. Hence these models do not justify any change in the internal structure of Ps, which is experimentally accessible by means of the contact density parameter. Recently we formulated a two-particle model in which only the electron is confined in the cavity, while the positron is moving freely and feels the medium via a positive work function. We present here a numerical treatment of the problem of calculating contact densities and pick-off annihilation rates, by using a variational method. Results are in agreement with experimental data for a large class of materials, and suggest a way to connect these data with pore sizes and positron work functions.

Both o-Ps parameters change (stepwise) when in the medium phase transitions occur. For a more complete picture of the structural changes occurring in the matter we suggest to use an additional plot, in the coordinates, (τ₃, I₃). The hydrocarbons are selected to show the advantages following from the presentation of the results in the intensity-lifetime (INTI) plot.

Opis:
The investigation of intermolecular free volumes in resorcinol was conducted under high pressure, hydraulic pressure and gas (argon or nitrogen) atmosphere. The sizes of free volumes were estimated basing on the mean lifetime of ortho-positronium (o-Ps). In the first case, a monotonous change of lifetime and intensity was observed for the o-Ps component while the range of pressure was 0-477 MPa. On the other case, the samples were put into the pressure chamber filled with argon or nitrogen in the range of pressure from 0 to 450 MPa. When the pressure chamber was filled with a gas, the appearance of an additional o-Ps component has been found. In the nitrogen atmosphere, the material crushed when the gas pressure reached about 200 MPa, and the mean lifetime of the longest o-Ps component increased.

Opis:
Within this work, the dechlorination of polyvinylchloride (PVC) chemical as a model by co-milling with eggshell was performed in a planetary ball mill in order to show that mechanochemistry can be utilized for the simultaneous treatment of two wastes, while the products of the treatment can be used in further applications. The products of the reaction are water-soluble calcium chloride ($CaCl_2$), which can be used e.g. for de-icing of roads in winter and organic residue on the basis of ethylene, which can be recovered as energy source. The highest dechlorination yield (almost 97%) was achieved under following milling conditions: molar ratio between Ca and Cl: 2.34, ball-to-powder ratio: 65, rotation speed of the planet carrier: 550 rpm, milling time: 4 h and material of milling media: tungsten carbide. The optimum conditions were then applied for the removal of chlorine from industrial waste - the abandoned PVC window parapet. In this case, 95% dechlorination was evidenced.

Opis:
Positronium will play a primary role in the next generation of antimatter experiments through the following antihydrogen production reaction: p̅ + Ps* → p̅e⁺ + e¯. In order to study antimatter physical properties (CPT (charge, parity, time) invariance and principle of equivalence test) it is necessary to keep this system at the lowest possible (sub-kelvin) temperatures. This requires the generation of a suitable flux of cold Ps atoms in a vacuum, a non-trivial requirement at the light of the present experimental results. In this paper we discuss the state of the actual knowledge on positronium formation and consequent emission from metallic surfaces and insulators and we show the opportunity to use suitable porous materials to cool positronium through collisions with the inner walls of the pores. We get a rough indication on the geometrical parameters of the pore and we propose a simple experiment to obtain the kinetic energy - and therefore the equivalent temperature - of emitted positronium without using a positron beam.

In order to assign the sites of positron annihilation, coincidence Doppler broadening spectra were measured for a highly oriented pyrolytic graphite crystal, graphite powder, multi-walled carbon nanotubes (MNTs) and cup-stacked carbon nanotubes (CNTs). The spectrum for graphite powder normalized to that for highly oriented pyrolytic graphite (HOPG) is almost flat in the momentum region from $7×10^{-3}$ to $13×10^{-3} m_{e}c$, having a ratio close to unity. The flat spectrum demonstrates that positrons injected into graphite powder annihilate in the interlayer spaces of piled graphite sheets, in the same manner as positrons in highly oriented pyrolytic graphite annihilate in the bulk. The coincidence Doppler broadening spectra for MNTs and CNTs are quite different from that for highly oriented pyrolytic graphite, which indicates that positrons injected into MNTs and CYTs annihilate not in the bulk, but on surface. The positron lifetime spectrum for multi-walled carbon nanotubes is analyzed in terms of a single component due to surface-trapped positrons, while that for CNTs is decomposed into three components attributable to para-positronium surface-trapped positrons and ortho-positronium. The difference between the coincidence Doppler broadening spectrum for CNTs and that for MNTs is explained in terms of positron annihilation on zigzag surfaces of CNTs which are composed of both graphite-sheet and graphite-edge planes.

Opis:
A theoretical analysis is performed of the phenomenon of anisotropic magnetic quenching of a positronium atom formed by polarized positrons in noncubic crystals oriented with respect to an external magnetic field. An initial polarization of positrons is shown to enhance an anisotropy of Ps magnetic quenching and to decrease the strength of magnetic field in which an anisotropy is maximal. A maximal anisotropic effect has been estimated for quasi-Ps in crystalline quartz and Ps complex in naphthalene single crystal.

Opis:
For the first time positronium is investigated in fine powders of MgO and Al$\text{}_{2}$O$\text{}_{3}$ using age-momentum correlation technique based on a relativistic positron beam. The application of this technique for investigating the interaction of positronium with the grain surfaces is discussed and compared with other techniques. The previously reported interaction of the positronium with paramagnetic centres is further studied. A qualitative interpretation of the spectra is given. In the Al$\text{}_{2}$O$\text{}_{3}$ samples we found some unexpected behaviour of the conversion quenching of ortho-positronium at irradiation induced paramagnetic surface defect.

Opis:
Systematic investigations have been performed using positron annihilation techniques on micrograins of crystalline powders (e.g., MgO, Al$\text{}_{2}$O$\text{}_{3}$, SiO$\text{}_{2}$) and on various zeolites (e.g., silicalite 1, Na-X, Na-Y, ZSM-5, mordenite) aiming at a better under standing of the formation and decay of the long-lived ortho-positronium states. The techniques were lifetime spectroscopy, Doppler-effect measurements and the recording of the full energy distribution of the annihilation radiation. The influences of heat treatment, sample evacuation and presence of gases were investigated. Lifetimes over 130 ns and o-Ps fractions of about 30% were found. A strong correlation of positron annihilation technique data with a water content of the samples was evidenced. Possible pictures of the formation and decay of ortho-positronium in porous media are discussed.

Opis:
Positron annihilation techniques are used for the structural investigation of solids but the interpretation of results in grainy and porous media is still unclear. A unique picture can be obtained assuming that the dominant process is Ps trapping in competing "extended free volume" sites. In samples with a large amount of free volumes near-saturation Ps trapping will rule the lifetime pattern, and very long lifetimes of over 100 ns might arise from o-Ps trapped in mesopores. It is shown that lifetime parameters must be corrected for the 3γ/2γ counting efficiency ratio. The results demonstrate the high sensitivity of Ps to mesopores in zeolites but also that Ps-trapping poses limitations on the applicability of lifetime to structural investigation in porous systems. The evolution of the lifetime spectra upon changes in the sample and measuring conditions should be considered in a complex way, observing not only changes in some selected components but in the whole lifetime pattern simultaneously.

A set of early chemical reactions in grapes of ionization (blobs) arising in tracks of fast electrons and positrons in liquids as well as formed by the Auger electrons in frozen aqueous media around decaying Mössbauer $\text{}^{57}$Co or $\text{}^{119m}$Sn nuclei is suggested. The mechanism predicts a correlated variation of the formation probabilities of intrablob final products, namely Fe$\text{}^{2+}$-Fe$\text{}^{3+}$ or Sn$\text{}^{2+}$-Sn$\text{}^{4+}$ ions, positronium atom and molecular hydrogen with variation of temperature, degree of crystallinity, concentration of electron scavengers. These correlations indicate on similarity of chemical processes as in blobs created by $\text{}^{57}$Co and $\text{}^{119m}$Sn after their decay as well as in blobs produced in tracks of fast positrons and electrons.

Opis:
Positronium formation probability was investigated as a function of irradiation time and temperature for some long-chain saturated hydrocarbons (alkanes). Intensity of ortho-positronium component in the lifetime spectrum depends on the concentration of trapped excess electrons, but also on concentration of radicals and ions acting as electron scavengers. The results indicate the existence of two kinds of electron traps; those which are not emptied by thermal treatment disappear after several days of positron irradiation.

Opis:
Background: In this work we studied the relationship between the enhanced expression of DR5 receptor and the effect of combination of TRAIL and ionizing radiation on cell cycle arrest and apoptosis induction in human leukemia cell line HL-60. Material and methods: DR5, APO2.7 and cell cycle were analyzed by flow cytometry. Proteins Bid and Mcl-1 were analyzed by Western-blotting. For clonogenic survival, colony assay on methylcellulose was used. Results: Ionizing radiation caused significantly enhanced positivity of DR5 receptors 24 h after irradiation with high doses (6 and 8 Gy). An increase of DR5 receptor positivity after a dose of 2 Gy was not statistically significant and application of TRAIL 48 h after irradiation did not increase the apoptosis induction. However, a decrease of radiation-induced G2 phase arrest and an increase of apoptosis were observed when TRAIL was applied 16 h before irradiation with the dose of 2 Gy. Incubation with 6 µg/l TRAIL for 16 h reduced D0 value from 2.9 Gy to 1.5 Gy. The induction of apoptosis by TRAIL was accompanied by Bid cleavage and a decrease of antiapoptotic Mcl-1 16 h after incubation with TRAIL. Conclusion: TRAIL in concentration of 6 µg/l applied 16 h before irradiation by the dose of 1.5 Gy caused the death of 63% of clonogenic tumor cells, similarly as the dose of 2.9 Gy alone, which is in good correlation with the enhanced apoptosis induction.

Opis:
Ostatni weimarski film Fritza Langa, Testament doktora Mabuse (Das Testament des Dr. Mabuse / Le Testament du Dr. Mabuse, 1933), dość powszechnie uchodzi za film antynazistowski. Ta renoma jest rezultatem m.in. niedopuszczenia filmu na niemieckie ekrany przez cenzurę Trzeciej Rzeszy oraz wielokrotnie przytaczanej w rozmaitych wariantach opowieści reżysera o jego jakoby natychmiastowej ucieczce z Niemiec w kwietniu 1933 roku po rzekomym spotkaniu z ministrem propagandy, Goebbelsem. W świetle dostępnych po śmierci reżysera dokumentów i znanych dziś faktów wiadomo już, że historia ta jest wymysłem Langa, jego „wyobrażonym filmem”. Na emigracji w USA Lang wzmocnił przekonanie opinii publicznej o antynazistowskim charakterze swego filmu poprzez manipulacje przekładem napisów przy okazji amerykańskiej premieryfrancuskojęzycznej wersji Testamentu doktora Mabuse w roku 1943. Jeszcze większych manipulacji na oryginalnym materiale filmowym reżyser dokonał, gdy na ekrany amerykańskie, pod tytułem The Crimes of Dr. Mabuse, wchodziła w roku 1952niemiecka wersja filmu: antynazistowską wymowę sugerowały bynajmniej nieliteralny przekład niemieckich dialogów w angielskim dubbingu i dokrętka expressis verbis objaśniająca, że akcja filmu toczy się między rokiem 1932 a 1939, gdy Niemcami rządzili „hitlerowscy przestępcy”. To właśnie tych ostatnich, wedle tej interpretacji, uosabia gang Mabusego/Bauma. Wprost przeciwną wymowę sugerowała wersja filmu na krótko dopuszczona przez Goebbelsa na ekrany Trzeciej Rzeszy – dokrętka o charakterze ramy narracyjnej (Rahmenhandlung) sugerowała osadzenie akcji w niedawnych, „mrocznych”czasach Republiki Weimarskiej, gdy krajem rządzili Żydzi…Analiza oryginalnej, pozbawionej manipulacyjnych zabiegów, wersji filmu dowodzi, że Mabuse to „puste miejsce”, które można „wypełnić” odmiennymi politycznymi i kulturowymi sensami, zawsze jednak związanymi z władzą, przemocą, zbrodnią, finansowymi matactwami i zakulisową manipulacją. Może jednak zamiast na siłę znajdować polityczną wymowę filmu, lepiej przyjrzeć się jego afiliacjom estetycznym: fabułą Testament doktora Mabuse dość zastanawiająco przypomina słynny film Roberta Wiene Gabinet doktora Caligari (Das Cabinet des Dr. Caligari, 1919), a próg i kres kina weimarskiego wyznaczają zatem dwa filmy o zbrodniczych psychiatrach, którzy sami popadają w szaleństwo i ostatecznie zostają pacjentami kierowanych przez siebie „domów wariatów”.
The last Weimar film by Fritz Lang, Das Testament des Dr. Mabuse / Le Testament du Dr. Mabuse (1933), is commonly regarded as anti-Nazi. Such an opinion results, inter alia, from the fact that the film was not authorised to go on general release in the Third Reich and from the story according to which the director must have escaped from Germany in April 1933 after an alleged meeting with Goebbels, minister of propaganda. In the light of the documents revealed after the death of the director and the facts commonly known now it has turned out that the whole story had been Lang’s fabrication, it is a ‘conjured-up film’. Being an expatriate in the USA Lang strengthened the widespread conviction of the anti-Nazi character of his film by manipulating the translation of the subtitles while the French version of his film was being released in the USA in 1943. The director made further manipulations on the original material of the film when its German version was being released in the USA in 1952 under the title of The Crimes of Dr Mabuse; its anti-Nazi character was suggested by the dialogues in the English-language dubbingtranslated from the German language; the translation was not literal (word-for-word) in the least. Some additional fragments of the film were shot later in order to explain that the plot took place between 1932 and 1939 when Germany was ruled by ‘Hitler’s criminal gang’. It was just ‘Hilter’s criminal gang’ – according to this interpretation – that is synonymous with the gang of Mabuse/Baum. Just the reverse interpretation was suggested by the version of the film released by Goebbels in the Third Reich – some extra scenes (Rahmenhandlung) shot then suggested placing the action in the ‘gloomy’ times of the Weimar Republic ruled by the Jews.The analysis of the original, devoid of any manipulations, version of the film proves that Mabuse is an ‘empty space’ that may be ‘filled’ with various political and cultural meanings, but always connected with the authorities, with violence, crime, financial chicaneryand behind-the-scenes manipulation.Yet, instead of looking for a political interpretation of the film, it might be interesting to have a look at its aesthetic affiliations: the plot of The Last Will of Dr Mabuse surprisingly resembles the famous film by Robert Wiene Das Cabinet des Dr. Caligari(1919), the last production of the Weimar Cinema. The two films describe criminal psychiatrists that became mad and eventually were locked in a mental hospital, which had been headed by them before.

The presently discussed outline project of an office building to be constructed in 28 Emilii Plater Street, Warsaw, was designed at the Institute for the Foundations of the Development o f Architecture, Warsaw College o f Science and Technology, within the frameworks o f a study on revalorization o f a major complex o f the built-up area dating from the second half o f the 19th and the early 20th century. In the area covered by the research, and situated in the centre of Warsaw, there is to be found a site once occupied by a building which has been pulled down. At the time of commencement of the said study there was already available a project design o f an office building to be raised in the said site. The project aroused, however, numerous objections since it referred neither to the dimensions and skyline nor the character o f the neighbouring tenement-houses. Hence two variants o f the project prepared as an attempt at introducing there architectonic forms which, though up-to-date, would be harmonized with the historical surroundings. The authors o f the project started from the assumption that the new building seen from more distant parts of the central area would make an impression o f one similar to the neighbouring nineteenth century houses and, at close quarters, of a structure typical of modern architecture. The inspiration were the characteristic traits of employed in moulding a tenementhouse, e.g. the rhythm o f window openings, crossections of the roof, more pronounced outline o f lower storeys and the crowning and light-and-shade effects of the bay windows and details. They were translated into a modern modular system o f shield walls and also of the roofs, built of plastic materials with the outer layer o f imported mat asbestic tile having a fine, slight relief or a layer o f plaster. The door and window trims are o f yellow metal. In the design of inner elevation large glazed surfaces and inclined walls were introduced in order to provide for better insolation of the interior.

Opis:
Doppler broadening and positron lifetime spectra have been measured for polypropylene films of constant thickness (≈ 50 μm) and different morphology that crystallized from melt at temperature 0, 100, and 120°C. The S -parameter vs. energy curves do not change in a systematic way with crystallinity of samples. It is supposed that decrease in the fractional free volume for samples of greater crystallinity is not seen in S-values because of their increase resulting from annihilation in defects present both in the crystalline regions and on the lamellae surfaces. Intensities of the components in the positron lifetime spectra: I$\text{}_{2}$ (τ$\text{}_{2}$=1.3 ns) and I$\text{}_{3}$ (τ$\text{}_{3}$≈ 2.3÷2.8 ns) show changes with crystallinity of samples. The evident trend is observed for the longer-lived τ$\text{}_{3}$-component intensity to decrease with crystallinity while the reverse is true for the shorter, fixed τ$\text{}_{2}$-component. The decrease in the intensity of the longer-lived component can result from reduction of the fractional free volume.

Opis:
The role of nonpolar optic phonon scattering and of umklapp acoustic phonon scattering is analyzed for a delocalized positronium atom in ionic crystals at elevated temperatures. At temperatures above which they become essential both of these scattering mechanisms contribute to the imaginary self-energy of positronium renormalizing its acoustic deformation potential constant. It was such a renormalization that was recently observed experimentally for delocalized positronium in MgF$\text{}_{2}$ crystal. We put forward the theoretical explanation of these experiments based upon the model of nonpolar optic phonon scattering of positronium. An effect analogous to that observed in MgF$\text{}_{2}$ is predicted for crystalline quartz above the temperature of (α-β)-phase transition.

Gas transport results in membranes made of epoxy resin with different cross linking densities and epoxy resin with dispersed few layer graphene fillers were discussed and compared in the framework of the free volume theory of diffusion. Transport in cellulose membranes was found to occur in the diffusion configurational regime. The physical description of the transport properties was based on positron annihilation lifetime spectroscopy measurements which allowed to evaluate experimentally the fractional free volume in epoxy resin membranes and the size of rigid elongated cavities in cellulose thin films.

Opis:
The primary goal of the Antihydrogen Experiment: Gravity, Interferometry, Spectroscopy (AEGIS) collaboration is to measure for the first time precisely the gravitational acceleration of antihydrogen, H̅, a fundamental issue of contemporary physics, using a beam of antiatoms. Indeed, although indirect arguments have been raised against a different acceleration of antimatter with respect to matter, nevertheless some attempts to formulate quantum theories of gravity, or to unify gravity with the other forces, consider the possibility of a non-identical gravitational interaction between matter and antimatter. We plan to generate H̅ through a charge-exchange reaction between excited Ps and antiprotons coming from the Antiproton Decelerator facility at CERN. It offers the advantage to produce sufficiently cold antihydrogen to make feasible a measurement of gravitational acceleration with reasonable uncertainty (of the order of a few percent). Since the cross-section of the above reaction increases with n⁴, n being the principal quantum number of Ps, it is essential to generate Ps in a highly excited (Rydberg) state. This will occur by means of two laser excitations of Ps emitted from a nanoporous silica target: a first UV laser (at 205 nm) will bring Ps from the ground to the n=3 state; a second laser pulse (tunable in the range 1650-1700 nm) will further excite Ps to the Rydberg state.

Opis:
Stepanov and Byakov's blob model for the formation of positronium can be considered as an extension of the spur model. However, it offers many extra possibilities and is more sound from the radiation chemistry point of view. A full coding of this model leads to non-exponential lifetime spectra, and standard multi-component analysis is no longer adequate for materials such as polymers. Age momentum correlation experiments were performed on linear PMMA at different temperatures and were analyzed with the non-exponential blob model. We show the adequacy of this model, and moreover an alternative explanation for the young-age broadening and delayed formation of positronium.

Improved mechanical properties, changes in crystallinity and morphology as well as higher glass transition temperature values were observed for the nanocomposites in comparison to the neat PA6. For the nanocomposite PA6/BZ-COCO, of better surface modification of platelets and better interaction between the polymeric matrix and the organobentonite, higher values of Young's modulus and yielding point together with higher contribution of larger free volume holes to free volume distributions occurred.

Opis:
The course of template removal from MCM-41 pores was investigated by positron annihilation lifetime spectroscopy. Two methods of removal were the object of interest: a decarbonisation after standard calcination procedure and a novel procedure - pyrolysis in vacuum. The shapes of positron lifetime spectra of decarbonised sample are determined by positronium quenching caused by presence of carbon deposit on the surface. Positron annihilation lifetime spectroscopy allows also monitoring the evolution of empty space inside pores. During pyrolysis no conductive carbon is produced, so consecutive stages of template material transformation are easy to observe. In the case of pyrolysis the effect of pore emptying is obtained at temperature 500 K, lower comparing to calcination and decarbonisation (820 K).

Opis:
Raman piezospectroscopy of high quality 6H-SiC crystals is presented. The crystals used in experiments were grown by the seeded physical vapor transport method. Uniaxial stress up to 0.9 MPa, obtained using a spring apparatus, was applied along [11-20] and [10-10] directions. It was found that the application of uniaxial stress led to different energy shifts of the observed phonon excitations in the investigated 6H-SiC crystals. The obtained pressure coefficients vary in the range 0.98-5.5 $cm^{-1}$ $GPa^{-1}$ for different transverse optical phonon modes. For longitudinal optic phonon modes pressure coefficients in the range 1.6-3.6 $cm^{-1}$ $GPa^{-1}$ were found. The data obtained could be useful in evaluation of local strain fields in SiC based structures and devices including epitaxial graphene.

The Jagiellonian positron emission tomograph project carried out in the Institute of Physics of the Jagiellonian University is focused on construction and tests of the first prototype of PET scanner for medical diagnostic which allows for the simultaneous 3D imaging of the whole human body using organic scintillators. The J-PET prototype consists of 192 scintillator strips forming three cylindrical layers which are optimized for the detection of photons from the electron-positron annihilation with high time-and high angular resolutions. In this article we present time calibration and synchronization of the whole J-PET detection system by irradiating each single detection module with a ²²Na source and a small detector providing common reference time for synchronization of all the modules.

Opis:
Highly porous IC3120 silica aerogel was subjected to the high pressure up to 450 MPa while the positron annihilation lifetime spectra were collected. The pressure was delivered to the investigated samples in two ways: by pistons and by gas (nitrogen) penetrating the aerogel. The evolution of all PALS parameters was discussed. With the increase of the pressure, shortening of ortho-positronium lifetimes (different, depending on the pressure method introduced) was observed. Similarity between the dependence of the longest-lived o-Ps component lifetime on the pressure, for the sample affected with nitrogen molecules and pure nitrogen was observed. It suggests, that the nitrogen fills the largest free volumes of the aerogel. The pressure exerted mechanically causes much smaller decrease of free volume available for positronium. The comparison of PALS results with the electron microscopy images, obtained after removing the pressure, confirmed that more intense and lasting changes were caused by affecting the aerogel with the pistons.

Opis:
Partial blocking of mesopores in the ordered MCM-41 silica by DC550 silicon oil was proposed as a preparation method of the material with controlled porosity and fixed pore size. The porosity of the samples with various content of DC550 was examined with the use of low temperature nitrogen sorption and positron annihilation lifetime spectroscopy. It was shown that the oil blocks the primary pores by forming the plugs near its entrances, but also partially locates in the interparticle spaces. The comparison of the results obtained from both investigation techniques was used to make the first attempt to obtain the calibration of ortho-positronium intensity, depending on pore volume. This is necessary to improve the utility of positron annihilation lifetime spectroscopy as a porosimetric technique. The need to take the migration of positronium to larger free volume into account is discussed.

Silver nanoparticles with continuous size distribution from 10 to 20 nm were incorporated into porous glass produced using sol-gel technique. Positron annihilation lifetime spectroscopy was used to compare obtained material with an undoped reference glass. The positron annihilation lifetime spectroscopy measurement were made in a broad temperature range (from - 180C to 200°C). The experimental lifetime values were compared with the predictions of the extended Tao-Eldrup model of the temperature range. Experimental results for the reference material were in agreement with the model, except for a small discrepancy at low temperatures. In doped material substantial changes and non-monotonous temperature dependences of intensity and lifetime values were observed. Heating the material to 200C resulted in reorganization of the material structure.

Opis:
A free photon Hamiltonian is linearized using Pauli's matrices. Based on the correspondence of Pauli's matrices kinematics and the kinematics of spin operators, it has been proved that a free photon integral of motion is a sum of orbital momentum and spin momentum for a half-one spin. Linearized Hamiltonian represents a bilinear form of products of spin and momentum operators. Unitary transformation of this form results in an equivalent Hamiltonian, which has been analyzed by the method of Green's functions. The evaluated Green function has given possibility for interpretation of photon reflection as a transformation of photon to antiphoton with energy change equal to double energy of photon and for spin change equal to Dirac's constant. Since photon is relativistic quantum object the exact determining of its characteristics is impossible. It is the reason for series of experimental works in which photon orbital momentum, which is not integral of motion, was investigated. The exposed theory was compared to the mentioned experiments and in some elements the satisfactory agreement was found.

Phase transitions in n-alkanes were observed by using the positron annihilation lifetime method. In the case of alkanes, application of pressure is equivalent to temperature lowering (1 K corresponds to ≈4 MPa). When argon at high pressure penetrates the sample one observes a non-monotonous dependence of the melting point on pressure. This effect is observed also in even-numbered alkanes, in which there is no rotator phase.

Opis:
A systematic study of zeolite precursor gels, zeolites, and products of their recrystallization to ceramics was carried out in presence of various alkali ions. The investigation of radiation damage induced by high-energy ion beam irradiation with swift heavy ions (Bi ions at 670 MeV energy with $4×10^{12}$ ion/$cm^2$ fluence) was also included. The shortening of lifetimes found after irradiation in ceramics might probably be ascribed to interactions of o-Ps with free radicals and other quenching agents created through the ion irradiation. These lifetime-shortening interactions probably partly hide the o-Ps trapping in free volume sites.

Ortho-positronium lifetime and intensity was measured as a function of temperature and pressure for some n-alkanes in which so-called "phase IV" appears. This phase is characterized by slightly increased ortho-positronium lifetime compared to low-temperature phases. It was found that the effect of quenching positronium by light does not appear in all phases from phase IV upwards. The lifetime in the rotator phases becomes equal to that in liquids, and only the change of positronium formation intensity allows to detect the solid-liquid transition in positron lifetime measurements.

Opis:
Positron lifetime parameters were measured for the spin-crossover complexes [Fe(R-1H-tetrazole)$\text{}_{6}$](BF$\text{}_{4}$)$\text{}_{2}$ (R = 1-ethyl, 1-n-propyl) and for the diamagnetic [Zn(1-n-propyl-1H-tetrazole)$\text{}_{6}$](BF$\text{}_{4}$)$\text{}_{2}$. Positronium forms with significant intensity in the studied compounds. The ortho-para conversion of ortho-positronium was used to follow the spin-crossover. Changes of the dynamic structure were found in the propyltetrazole complex between 150 K and 90 K.

Opis:
The effects of vapour absorption on positron annihilation in cross-linked polymer were investigated. Contrary to linear polymers, absorption of vapour in cross-linked resin leads to the shortening of o-Ps lifetime. In vacuum absorbed molecules diffuse out. At room temperature desorption of hexane and hexanol is not complete; full elimination of absorbed molecules requires sample temperature increase.

Opis:
Crystal-melt interface was investigated during Czochralski growth of SrLaGaO$\text{}_{4}$ and SrLaAlO$\text{}_{4}$ crystals on ⟨001⟩ oriented seeds. Relations between the ratio of the core diameter, grown on (001) plane, and the crystal diameter, as a function of seed rotation speed were determined. It was confirmed that it is possible to control the core diameter during the crystal growth. A new module was introduced into the crystal growth controlling program. It enables to estimate the surface tension coefficient between crystal and melt at the beginning of crystallization. This value is then used to compute proper corrections for automatic weighting system.

Opis:
Role of trapped and solvated electrons in Ps formation is discussed. Combination of thermalized positron with such electrons is possible from the viewpoint of the energy balance and may results in Ps formation. This process proceeds during all e$\text{}^{+}$ lifetime in matter. Fitting of raw experimental e$\text{}^{+}$ - e$\text{}^{-}$ annihilation spectra has to be based on an adequate physical input, which often leads to necessity of nonexponential deconvolution of the spectra. We have interpreted the Ps formation data in polyethylene, ethylene-methylmethacrylate and polymethylmethacrylate in dark and in light vs. time of the measurement and temperature. Parameters characterized accumulation of trapped electrons and their recombination with counter ions and positrons are obtained.

Opis:
Positron lifetime spectra were measured for a series of odd-numbered n-alkanes from C$\text{}_{11}$H$\text{}_{24}$ to C$\text{}_{19}$H$\text{}_{40}$ as a function of temperature and pressure. The ortho-Ps lifetimes in the rotator phase and the increase in intensity at the transition to that phase can be explained by location of Ps in the vicinity of kink-type conformers. The relation between o-Ps lifetime and molecule length can be described in the framework of extended Tao-Eldrup model. One can eliminate the effect of intensity rise in time by sample illumination or by application of high pressure. A decrease in temperature by 1 K is equivalent to an increase in pressure by about 4 MPa.

Opis:
The quadrupole interaction of positronium in noncubic defectless crystals has been investigated theoretically. It is shown to lead to the weak anisotropy of positronium magnetic quenching. The temperature dependence of the quadrupole coupling constant and the estimations of the magnitude of the anisotropy are obtained for delocalized positronium in crystalline quartz. The significant magnitude of the anisotropy is predicted for "anomalous" positronium in oriented crystalline polymeric structures.

Opis:
Przedmiotem artykułu jest popularna na początku XXI wieku narracja o społecznym wykluczeniu i prześladowaniu nastoletnich geeków i ich słusznej zemście oraz to, w jaki sposób przyczyniła się ona do wytworzenia tożsamości niedobrowolnych celibatariuszy (inceli). Jako przykład modelowej narracji sprzyjającej wytworzeniu się incelskich fantazmatów omawiany jest musical Dr. Horrible’s Sing-Along Blog Jossa Whedona z 2008 roku. W momencie powstania film miał traktować o antagonizmie geeków i prześladujących ich jocków, a we współczesnym kontekście ma zupełnie odmienną wymowę.
The paper discusses the narrative about social marginalization and bullying of geeks and their justified revenge which has been widely popular in the first decade of the 21st Century. Said narrative is discussed as one of the factors which have contributed to the emergence of the incel identity, and is exemplified by Joss Whedon’s musical Dr. Horrible’s Sing-Along Blog. At the moment of its creation the 2008 movie was supposed to portray the antagonism between the geeks and the jocks who torment them. Nowadays, in a changed social context, the movie’s message is very much different.

Opis:
In 2004 heretofore-unknown cellars were discovered in the town hall in Zielona Góra; the interiors were not included in the inventory of the building carried out in 1958. This fact justified the necessity of embarking upon architectural studies whose purpose was to examine the form and successive phases of the transformation of the Gothic edifice. In 2006 a team headed by Dr. Czeslaw Lasota conducted architectural research, which coincided with the repair of the town hall northern wing, initiated in July of that year. Numerous layers of plaster revealed a brick wall of the Gothic town hall to which the repaired wing had been added in the course of the nineteenth century. In the interior of the northern wing staircase the conservation and restoration realised at the end of 2006 came across a Gothic gable with lavish blind arch windows, fragments of a panel below the gable, an outline of the northern gable, and a tower. Other discoveries included remnants of cloth hall stalls built at the same time as the town hall, and adjoining the latter to the east. At the same time, the conservators disclosed the original plaster of the blind windows and window openings, which at the beginning of 2007 were subjected to complex conservation-restoration. Particular importance was attached to the relics of the lime plaster, which are examples of the scarce original early medieval plaster preserved in secular buildings in the voivodeship of Lubusz.

Opis:
The comparison of pore size distributions obtained with the use of two porosimetric methods: low temperature nitrogen sorption (LN2) and positron annihilation lifetime spectroscopy (PALS), was performed for porous silica monoliths. Four investigated samples were prepared under various synthesis conditions. Nitrogen sorption showed the presence of bottle-shaped pores in all investigated samples. In addition, it seems that the presence of methanol during synthesis influences porosity to a greater extent than organic additives. Quite good agreement between the LN2 and PALS results was observed only for the silica monolith synthesized with β-cyclodextrins as pore directing agent. The biggest discrepancy in the results obtained from these two techniques was observed for the silica gel synthesized with no additives. The origin of such discrepancies, taking into account the shape of pore size distribution and deficiencies of data analysis techniques, is discussed.

Opis:
Positronium (Ps) formation during self-irradiation by positrons was observed in n-alkanes of various carbon chain length. The rise of Ps intensity with time of irradiation is the result of positronium formation with trapped excess electrons. In the range T < 190 K the saturation value of positronium intensity changes with temperature mainly due to the change of positron mobility. With the increase of the irradiation dose the process of charging traps is slowing down and this effect is ruled mainly by interaction of excess electrons with ionization products during electron's migration to the traps.
