Opis:
Figura „człowieka”, który przekazuje wiadomość ojcu o narodzinach syna – Jeremiasza jest w interpretacji problematyczna, gdyż człowiek ten nie zaciągnął żadnej winy wobec proroka, a został przez niego przeklęty. Tego rodzaju postępowanie mogło wiązać się z zakazem złorzeczenia ojcu lub matce (zob. Wj 21,17; Kpł 20,9) oraz zakazem bluźnienia Bogu (zob. Wj 22,27; Kpł 24,10‒16). Nie mogąc bezpośrednio złorzeczyć tym, którzy powołali go do życia, prorok czyni to pośrednio wobec tego, który ogłosił wiadomość o jego narodzinach. Posłaniec może być również uosobieniem samego Jeremiasza. Obydwaj głosili prawdę – dobrą nowinę. Obydwóm groziła za to śmierć. Żaden z nich nie zaciągnął winy wobec tych, którzy zagrażali ich życiu.
The figure of ‘the man’, who gives Jeremiah’s father a message about son’s birth, is in the interpretation problematic as this man was not at fault to the prophet, yet he was cursed by him. This kind of behavior could be connected with a ban on cursing mother or father (see Exod 21,17; Lev 20,9) and a ban on blaspheming against God (see Exod 22,27; Lev 24,10‒16). Jeremiah being unable to curse directly those who have called him into being, indirectly does it towards the person, who has announced his birth. This messenger may also be a personification of Jeremiah. As they both promulgated the truth-the Good News and could be sentenced to death. None of them was against those who were threatening their lives.

Opis:
In Sir 14:20 – 15:10 Sirach continues his teachings concerning the acquisition of wisdom (cf. 1:1-10; 4:16-19 and 6:18-37) (the exegetico-theological analysis conducted in this article is based on the Greek version of the fragment). In the pericope the author presents the sage as a model and an example to follow for all those who wish to acquire wisdom. The pericope under analysis here comprises two parts. The present article focuses on the first one (14:20-27), in which Sirach concentrates on the actions the sage undertakes to acquire wisdom. The second section (15:1-10) in turn makes use of three metaphors to present the actions of wisdom throughout the process of a man’s search for it. The first part of the pericope (14:20-27) can be further divided into three sections. In the first one (14:20-21) Sirach praises the man who seeks wisdom, emphasizing his intellectual engagement (in the form of contemplating or pondering) as the basis for reaching the aim and finding wisdom. The second part (14:22-25) presents the actions aimed at acquiring wisdom with the use of three metaphors: the first is that of hunting (14:22), and the second – that of spying (14:23), even though verses 21:23-24 include a prohibition and a harsh reprimand against peeping or eavesdropping. The third metaphor, the most developed of all three, refers to camping next to wisdom (14:24-25). In the final section of part one (14:26-27) Sirach presents the promises made to those who strive to acquire wisdom, namely protection from danger and living close to wisdom.

The Sage – The Model of a Wisdom-Seeker (Sir 14:20 – 15:10).Part II: Wisdom’s Actions and a Warning for the Sinner (Sir 15:1-10)         The second part of Sir 14:20 – 15:10, that is 15:1-10, consists of five sections: 15:1 functions as an introduction, vv. 2-3 focus on wisdom’s actions towards the one who seeks it, vv. 4-6 contain promises made to the person who has acquired wisdom, vv. in turn 7-8 constitute a warning for the fool – that is the sinner, while in the concluding part of the pericope analyzed in the present article (vv. 9-10) Sirach speaks of God’s worship as the culmination of the efforts made in order to acquire wisdom.          Mere intellectual efforts do not suffice to acquire wisdom. It is wisdom itself that helps those who seek to attain it (vv. 2-3; the metaphors of the mother and wife, of being fed the bread of knowledge and the water of wisdom). Wisdom is personified as the guide in the process while at the same time remaining the object being sought. Its actions towards the man who strives to acquire it are akin to God’s actions towards Israel and all the believers. The promises made in 15:4-6 pertain both to the wisdom-seeker’s earthly existence (he will never fall nor will he be disgraced; on the contrary, he will be elevated and awarded with joy) and his afterlife (his descendants will remember him forever). In 15:7-8 Sirach expresses a warning directed to fools, that is sinners. They will never attain wisdom for their conduct defies wisdom’s requirements for those who seek it (fear of God, knowledge of the Law and contemplation both of wisdom and the commandments). The author concludes by saying that God’s worship constitutes the apex of attaining wisdom, a sign that one has actually acquired it. Fools and sinners cannot worship God for they do not submit to God’s command and hence will never acquire wisdom. The article also compares the theological message of 14:20 – 15:10 concerning wisdom with other fragments of the Book of Sirach that refer to the seeking and finding of wisdom (1:1-10; 4:11-19 and 6:18-37).

Opis:
In Kol 1, 15-20 sieht die heutige ntl. Forschung ein älteres Christuslied. Man ist sich auch ziemlich einig bezüglich der Abteilung und der Gliederung des Hymnus in zwei Strophen (15-18a; 18b-20). Umstritten bleibt weiterhin die Urform des Liedes und dessen religiös-gesehichtlicher Hintergrund. Schon diese beide Faktoren nötigen zu einer gründlichen und vielseitigen Untersuchung von Kol 1,15-20. Der Verf. nimmt vor allem Stellung gegen die allgemeine Auffassung, die ältere Schicht des Hymnus (wie man sie auch sehen sollte) in ihrer „aufweisbaren” Doppelform (protologischer Teil —soteriologischer Teil), stamme aus einer Verfasserhand. Offenbar lag zunächst ein protologischer Teil zu Grunde, der (was nicht ganz ausgeschlossen ist) mit einer Epiphanieaussage endete. Diesen Teil überarbeitete der Verfasser des Kolosserbriefes und entwarf einen zweiten kosmisch orientierten soteriologischen Teil. Zu diesem Ergebnis führen den Autor einerseits stilkritische und literarkritische Beobachtungen, anderseits wird für die zweite Strophe eine Anzahl von Texten aus dem Corpus Paulinum angeführt, die eine sehr verwandte kosmische Soteriologie aufzeigen. Das wäre auch ein Fingerzeig dafür, das Paulus selbst der Verfasser der zweiten Strophe des Liedes ist und zugleich des Briefes. Die Verbindung von Protologie und Soteriologie wäre also Paulus zuzuschreiben.

Opis:
So in den einzelnen Begriffen wie im ganzen Klima der Perikope Jes 32, 15-20 kommt ihre starke eschatologische Prägung zum Ausdruck. In dieser endzeitlichen Epoche wird „der Geist von Höhe” die entscheidende Rolle spielen, der auf das neue Gottesvolk ausgegossen werden soll. Seine zukünftige Wirkung gilt aber merkwürdiger Weise nicht zuerst den Menschen, sondern verändert völlig die Natur. Es entsteht ein idealer Lebensraum, wo dann unter dem Einfluß des Geistes wesentlich neue Verhältnisse zu Gott und den anderen herrschen werden. In diesem Bild ist eine gewisse Ähnlichkeit zum Schöpfungsbericht vom Gen 1-2 zu sehen. Am wahrscheinlichsten hat solche Gestaltung Jes 32, 15-20 hier ihren Grund. Auf diese Weise klingt die Endzeit an die harmonische Paradieszeit an.

Unsere Informationen über genealogische Themen, besonders die der Grenzerfamilien sind oft unvollständig.

Im Archivbestand der Diözese Luck hat der Autor der vorliegenden Publikation ein umfangreiches genealogisches Material gefunden. Es wird hier die Familie Jełowicki, Wappen Bożeniec präsentiert, die zahlreich in Wołyń auftritt. Matrikelmaterialien der Diözese Luck (aus Geburts-, Trauungsbüchern und Büchern der Verstorbenen) sind oft die einzigen, die sich bis auf unsere Zeit in Form von Abschriften erhalten haben. Der Verfasser selbst benutzte oft eine solche Art von Matrikelbüchern. Es soll auch darauf hingewiesen werden, dass diese den Tag der Eheschließung, Geburt oder Bestattung betreffenden Informationen ziemlich genau sind.

Opis:
The article contains a detailed exegesis of the Christological hymn in Col 1:15-20, highlighting the links between the theology of creation and kerygmatic theology. The first strophe (1:15-18a) emphasizes the author’s intention to show the function of Christ in the creation of the world, whereas the second one (1:18b-20) exposes the fact that Christ’s passion, death and resurrection were key moments in the history of the world, comparable only to the work of its creation. It is shown that both events are closely related in the hymn because reconciling the world to God in the blood of Christ is meant to be the completion of the work of creation, resulting in restoring a harmonious relationship between God and man.

Opis:
Ende der 70er Jahre besaß die Bibliothek der Katholischen Universität Lublin in ihren Sammlungen 131 Inkunabeln. Sie wurden von Maria Kunowska (die Publikation in ABMK, Bd. 36, 1978) bearbeitet. Zur Zeit (1999) besitzt die Bibliothek 137 Inkunabeln. Sie stammen aus verschiedenen europäischen Druckereien und Buchbinderwerkstätten. Von ihnen wurde eine Gruppe von 29 in Venedig gedruckten Inkunabeln ausgesondert. Der in den 90er Jahren gemachte Versuch einer genauen Datierung einzelner Einbände und der Bestimmung ihres Entstehungsortes brachte interessante Beobachtungen über die Entwicklung des mittelalterlichen Einbandes vom Anfang des 16. Jhs. Es ist sichtbar geworden, dass Krakau zum Zentrum der Buchbinderei geworden war, zu welchem die Zentren von Südpolen, Schlesien und sogar von Böhmen hinneigten, wobei eine gemeinsame Quelle dieser Invention zweifellos Italien war. Eine eingehende Analyse der einzelnen Einbände hat gezeigt, dass Buchbinderwerkstätten ein breites Spektrum eigener Methoden und technischer Lösungen verwendeten. Die Buchbinder waren jedoch nicht nur Handwerker: sie verwendeten ( oft erfinderische) Prinzipien der Verzierungskomposition und waren an künstlerischen und Stilproblemen interessiert. Die Art der Verzierungen konnte für die gegebene Bibliothek oder Werkstatt einheitlich sein; es gibt aber auch viele Beispiele eines freien Schaffens. In der Verzierung der Bucheinbände finden natürlich die allgemein herrschenden Stiltendenzen sowie die sich absondernden nationalen Stile ihren spezifischen Ausdruck. Die Technik der Einbände änderte sich in kleinen Werkstätten oder in Zentren, wo der Hang zu einer Art der Einbände festverwurzelt war, über Jahrzehnte lang nicht, die Ornamentik dagegen veränderte sich mit der Mode und nach aktuellen Tendenzen in der Architektur, Skulptur, Malerei, im Handwerk, in Kleidungs- und Schmuckstilen. Ähnliche ( oder geradezu gleiche) dekorative Elemente finden wir sowohl auf den Stoffen als auch auf den Bucheinbänden. Zum Beispiel die Malerei von der Wende des 15. zum 16. Jahrhundert liefert viele Beispiele für die Verwendung des Musters des stilisierten Granatapfels auf den Tracliten der Zeitgenossen. auch die Einbände aus dieser Zeit verwenden oft das Motiv. Die so durchgeführte Vergleichsanalyse schuf einen Grund dazu, die untersuchten Bucheinbände einer bestimmten geschichtlichen Epoche zuzuschreiben und ihren wahrscheinlichen Entstehungsort zu bestimmen.

We present an influence of the local chemical ordering on the electronic and magnetic properties of Ni$\text{}_{1-x}$Cu$\text{}_{x}$MnSb alloys. The band structure and the magnetic moments were calculated by the spin-polarised linear muffin-tin orbital in the atomic sphere approximation method for the experimental values of the lattice parameters. The magnetic moment of Mn increases from 3.8 μ$\text{}_{B}$ for x=0 to 4.18 μ$\text{}_{B}$ for x=1.

CePd$\text{}_{3}$ has the highest reported Seebeck coefficient (S ~ 125 μV/K), when doped appropriately, among all rare-earth compounds. This high value is explained as a result of the placement of the cerium f$\text{}^{1}$ level.

The electronic structure of the UFe$\text{}_{2}$ compound was studied by X-ray photoemission spectroscopy and ab initio self-consistent tight binding muffin tin orbital method. This compound crystallizes in a cubic Laves phase. The calculated valence band spectrum is characterized by two peaks due to U(5f) and Fe(3d) states. We have found a good agreement between the experimental valence band spectrum and theoretical ab initio calculations. The carrier concentration estimated from the Hall effect amounts to ≈10$\text{}^{22}$ cm$\text{}^{-3}$.

Opis:
Spin relaxation in degenerated two-dimensional (2D) electron gas is studied by measurements of the magnetic field dependence of the weak antilocalization corrections to the conductivity in GaInAs quantum wells. Consistent quantitative (up to order of magnitude) description of weak antilocalization data on GaAs like heterojunctions and quantum wells was obtained. Our results show that spin precession around the effective magnetic field direction as described by the Dyakonov-Perel model is the main spin relaxation mechanism in degenerated 2D electron gas in semiconductors with no inversion symmetry.

Opis:
The first-principle band structure calculations for Ru₃Sn₇ and Mo₃Sb₇ were carried out using the full-potential linearized muffin tin orbital method. It was shown that the valence band contribution is mainly due to the 4d electrons of Ru(Mo), while the contribution from the 5p-Sn(Sb) orbitals is relatively small. Furthermore, the 4d and 5p orbitals located near the Fermi level have the non-hybridized characters, thus presumably contributing independently to the total density of states. A comparison of the density of states of two compounds reveals an essential difference in the structures and magnitudes. We estimated the mass enhancement factor and Stoner product and discussed these differences regarding to electronic and magnetic behaviour of these compounds.

Opis:
An original method of treating the kinetic and exchange-correlation energies functionals in terms of many particle interactions was developed. It is based on utilizing the local density approximation. The total electron density, extracted from the ab initio band structure calculations, is expressed as a linear superposition of contributions from the individual pseudoions embedded in the uniform background. The explicit expressions for the pair and triplet potentials are presented. The general form for the part of the pair interatomic interactions caused by the kinetic and the exchange-correlation effects is obtained. Relationship between the developing approach and the perturbation theory in pseudopotential is analysed. Unlike the perturbation theory the advanced approach allows one to calculate accurately the so-called reducible contributions to the pair potential arising from the n -particle (n>2) interactions. It corresponds to summing certain series in pseudopotential. Contribution of the electron-nonlocal pseudopotential interactions to the pair interatomic ones is considered within the concept of the fully separable pseudopotentials.

All components of nuclear quadrupole splitting tensors of the chlorine nuclei in inertial and in principal quadrupole axes were determined. It is shown that in methylene halide molecules nuclear quadrupole information leads to a value for ∠(XCX) which is systematically larger than ∠(XCX) defined by the positions of the nuclei. Some novel features of the spectrometer are also described.

Opis:
Structural, elastic, electronic, and optical properties of cubic perovskite $CsCaCl_3$ are calculated using the full-potential linearized augmented plane wave method in the density functional theory. The exchange-correlation potential is evaluated using the local density approximation and generalized gradient approximation. Further, the modified Becke-Johnson potential is also applied for studying the electronic and optical properties. The calculated structural properties such as equilibrium lattice constant, the bulk modulus and its pressure derivative are in good agreement with the available data. The elastic properties such as elastic constants, anisotropy factor, shear modulus, Young's modulus and Poisson's ratio are calculated. The calculations of electronic band structure, density of states and charge density show that this compound has an indirect energy band gap (M-Γ) with a mixed ionic and covalent bonding. Calculations of the optical spectra such as the real and imaginary parts of dielectric function, optical reflectivity, absorption coefficient, optical conductivity, refractive index, extinction coefficient and electron energy loss are performed for the energy range of 0-30 eV. Most of the studied properties are reported for the first time for $CsCaCl_3$.

The electronic structures are reported for two crystallographic structures: orthorhombic TiNiSi type and the hexagonal ZrNiAl-type structure. We also study the influence of hydrogenation on the electronic structure of $HoNiSnH_{0.66}$. Ab initio calculations have shown that in the both type of structures the Fermi level is located at the 4f peak of Ho, however we observed the modification of 3d peaks from nickel atoms below the Fermi energy. The hydrogenation leads to increase of the density of states at the Fermi level.

The calculations were performed by first principles full-relativistic full potential local orbital method within the local spin density approximation. The calculations results show the metallic character of GdNiSb compound in the high-temperature phase with hexagonal $AlB_2$-type structure.

Opis:
The weakly bound van der Waals dimer between a molecule of cyanoacetylene and an argon atom was observed by rotational spectroscopy of supersonic expansion. Cyanoacetylene was generated in situ from vinyl cyanide precursor by means of a high voltage discharge just downstream of the expansion nozzle. Both $\text{}^{b}$R- and $\text{}^{b}$Q-type rotational transitions were measured and rotational, centrifugal distortion, and nuclear quadrupole splitting constants were determined. Analysis of the data shows that ground state geometry of the dimer is characterised by R$\text{}_{cm}$=3.65Å andθ=94.9º, with the Ar atom shifted from the position above the cyanoacetylene centre of mass in the direction of the CN group.

The three lowest J transitions, at frequencies from 2 to 8 GHz, have been studied at conditions of supersonic expansion. The complicated hyperfine splitting structure arising from the three non-equivalent quadrupolar nuclei has been assigned and fitted. The resulting spectroscopic constants and the derived molecular quantities are compared with those for other isotopomers, as well as with experimental and calculated results for other linear dimers involving dinitrogen. A revised value for the nuclear quadrupole splitting constant for free nitrogen molecule,ρ(N)=-5.3(1) MHz, is also derived.

Opis:
Lithium amide $(LiNH_{2})$ and imide $(Li_{2}NH)$ have recently attracted much attention as part of the Li-H-N system suitable for hydrogen (H) storage applications. However, the ground-state imide structure is still unknown with at least six candidate structures, with ground state energies all very close to one another. In order to discover possible pathways for the imide-amide-imide transformations during the hydrogen absorption/desorption cycles, we have examined the molecular structures involved (along with their changes during these processes) using ab-initio calculations based on the linear combination of atomic orbitals (LCAO). In addition, the influence of Li substitution by some other elements of interest on the system behaviour was investigated. These analyses were complemented by density functional theory (DFT) calculations of several crystal structures appearing in the processes. In this way a thorough insight into the structures and the processes taking place at atomic level is attained, providing a starting point for understanding these complicated systems, and the mechanisms governing their transformations.

The electronic structure of the tetragonal RMn$\text{}_{2}$Ge$\text{}_{2}$ (R = Ca, Y, La, Ba) antiferromagnets is presented using the self-consistent Korringa-Kohn-Rostoker method. According to the neutron refinements, two types of collinear antiferromagnetic structure are taken into account: AF$\text{}_{1}$ for YMn$\text{}_{2}$Ge$\text{}_{2}$ and AF$\text{}_{2}$ for the other compounds. The calculated magnetic moments on Mn: 2.17μ$\text{}_{B}$ (YMn$\text{}_{2}$Ge$\text{}_{2}$), 2.84 μ$\text{}_{B}$ (CaMn$\text{}_{2}$Ge$\text{}_{2}$), 2.95 μ$\text{}_{B}$ (LaMn$\text{}_{2}$Ge$\text{}_{2}$), and 3.47 μ$\text{}_{B}$ (BaMn$\text{}_{2}$Ge$\text{}_{2}$) remain in good agreement with the neutron data (in μ$\text{}_{B}$) 2.20, 2.67, 3.05, and 3.66, respectively. As seen on antiferromagnetic density of states, all systems are metallic, however BaMn$\text{}_{2}$Ge$\text{}_{2}$ is found near semimetallic limit. The total energy Korringa-Kohn-Rostoker computations on CaMn$\text{}_{2}$Ge$\text{}_{2}$, performed in both antiferromagnetic phases, result in preferring of the AF $\text{}_{2}$ structure.zap

Opis:
A description of the onset of dissipation in the integer quantum Hall effect is given, where the electric field across the sample is expressed through a time dependent vector potential. This brings the essentially time dependent, non-stationary nature of the problem into focus. The electric field induces transitions between the levels of the disorder broadened Landau band. Above a critical electric field the particles are driven upwards in energy space beyond the Fermi level, which leads to dissipation since the accumulated energy is lost to the heat bath after τ$\text{}_{in}$, the time between two inelastic events. Thus the dissipated power is obtained without the use of the traditional (linear response) transport formulae. As an application we investigate the dissipation in the corner region of a Hall bar. The results are in reasonable accordance with recent experiments exploiting the fountain pressure effect.

Opis:
In this paper, the effect of tool tilt angle on tensile-shear failure load and weld zone properties for 1050 aluminum plates, welded by friction stir lap welding, were investigated. For this purpose, tool tilt angle was varied from 0° to 5° under the constant other parameters, such as tool geometry, tool rotation speed of 1200 rpm and tool travel speed of 30 mm/min. The tensile-shear test was employed to test the mechanical properties of the joint. Optical microscope examinations, microhardness and temperature measurements were also performed in weld zone of lap joints. According to overall results, the tool tilt angle has a reasonable influence on the joint soundness and weld defect formation. If the tool axis was perpendicular to plate surface or a larger tool tilt angle was used, such configurations had harmful effect for the weld zone. In such case the tensile-shear failure load dropped from 4853 N to 2799 N. Recorded peak temperatures varied from 381°C to 438°C in the weld center. The measured mean hardness values of the stir and heat-affected zones were 31.5 HV and 28.3 HV, respectively, which are lower than that of aluminum 1050 base metal (40.7 HV).

Opis:
High quality single crystals of some representatives of half-Heusler family were grown from Bi-flux. For single crystals characterization, X-ray diffraction and scanning electron microscopy techniques were used. The low-temperature physical properties of the synthesized crystals were determined by means of magnetization, magnetic susceptibility, electrical resistivity and heat capacity measurements. For each compound but LuPtBi, the electrical resistivity varies in a semimetallic manner at high temperatures, and exhibits a metallic character at low temperatures. LuPtBi is metallic in the whole temperature range studied. The bismuthides HoPdBi, LuPdBi, LuPtBi and YPtBi were found superconducting below the critical temperature $T_{c}$ = 0.7, 1.8, 0.9, and 0.96 K, respectively. For the compounds GdPdBi, DyPdBi and HoPdBi, an antiferromagnetic ordering was found to set in below $T_{N}$ = 12.8, 3.7, and 1.9 K, respectively. HoPdBi is thus an intriguing material in which both cooperative phenomena coexist.

Opis:
Full potential linearized augmented plane wave band structure calculations were performed for hexagonal $RENi_5$ (RE = rare earth) compounds in order to investigate reproducibility of lanthanide contraction by ab initio studies. The a and c parameters were optimised using a paraboloid fit, starting from the same initial values for all compounds studied. The trend in lattice parameters across the RE series obtained from the calculations was found to be in general agreement with experimental data. A comparison of results obtained by generalized gradient approximation and generalized gradient approximation with additional Coulomb correlations calculations is presented for several double counting schemes.

Opis:
Inclusion of spin-orbit interaction in density functional theory calculations of PbTe band structure leads to wrong results concerning the symmetry of valence and conduction band wave functions. Using two ab initio codes: OpenMX and Quantum Espresso we show that changing the spin-orbit coupling strength in pseudopotentials for Pb it is possible to obtain proper energy gap and wave functions of proper symmetries.

Opis:
The Ce-based 2:3:9 series of compounds are known for strongly correlated 4f-electron behaviour. Here, we report for the first time a study of the thermal conductivity κ(T) in zero and 9 T magnetic field for Ce₂Ru₃Ga₉ across the temperature range 2 K ≤ T ≤ 300 K. The zero-field temperature dependence of κ(T) exhibits a pronounced maximum, characteristic for metals with large electronic mean free path and towards room temperature κ(T) starts behaving in a manner usually attributed to the enhanced electron-phonon coupling. Based on the Wiedemann-Franz law the electronic and lattice contributions to the thermal conductivity were estimated. In high temperature region a distinct step-like anomaly at T* = 203 K has been observed which signals a putative phase transition, probably of phononic or lattice origin. We furthermore discuss the effect of applied magnetic fields on the thermal transport in Ce₂Ru₃Ga₉.

Opis:
This study deals with the weldability and assessment of the friction stir spot welding of dissimilar CuZn30 brass/DP600 steel couple. The effects of axial tool load and tool hold time were evaluated in the joining experiments. The tool load forces of 3.2-4.8 kN and the tool hold times of 8 s and 12 s were applied to brass/steel bimetal sheets. Tensile-shear test was employed to investigate the mechanical properties of the joint. Optical and scanning electron microscopies were utilized to characterize the microstructure of the joint having the better mechanical performance, as well as the microhardness test. Temperature measurements were also performed between the lapped sheet faces. The results show that the vertical tool load value has reached more significant influence than the tool hold time. Furthermore, the tensile-shear failure load has increased with increasing tool load and hold time and has reached the highest value of 4.6 kN. The EDS analyses on the fractured surface depict that the copper and zinc concentrations are similar to those of CuZn30 base metal. A peak temperature of 607°C was measured in the weld centre of this joint. No significant microstructural change was observed in the steel sheet, while the fine grains with onion rings were revealed in the brass. Different hardness values were measured depending on microstructural change in the weld zone. Although the onion rings made a contribution to the microhardness, a softened stir zone (129.8 HV), with regard to the brass base metal (149.1 HV), was observed.

Opis:
NiTi-based shape memory alloys are metallic materials exhibiting remarkable response to mechanical and/or thermal loading, e.g. superelasticity, pseudoplasticity or one-way shape memory effect. They can be engineered into structures of micro-size dimensions, hence, they appear promising for application in micro-electromechanical systems. For their efficient utilization, appropriate characterization is important. Due to relative simplicity, indentation represents a very standard and popular technique for basic characterization of metallic materials providing information about stiffness and hardness. Moreover, it can be used for identification of other events in the material. This study aims to verify applicability of the recently developed constitutive model for NiTi-based shape memory alloy in simulations of nanoindentation tests. The model is fitted to a particular sample material using experimental data, and a series of simulations mimicking tests at various temperatures is performed. Since the model also captures two-stage martensitic transformation via the intermediate R-phase, its influence on the simulations is investigated as well. It is confirmed that spherical indentation is a suitable method for simple and fast detection whether the material is in superelastic or pseudoplastic regime.

Opis:
Bremsstrahlung photons are created by electron beams de-accelerating in electric field (coupling with a thin radiator) and are used in a variety of different fields. In nuclear physics experiments it is important to transport and focus the created photon beam into the experimental cavity. Here angular distribution of the photon beam is one of the important parameters, which should be known. In this study a FLUKA simulation has been done to obtain angular distribution of photon beam created by interaction of 40 MeV electron beam with the tantalum (Ta) radiator of varied thickness, which is planned to be used in bremsstrahlung photon facility at TARLA (Turkish Accelerator and Radiation Laboratory in Ankara). TARLA will be the first facility of Turkish Accelerator Center project.

The temperature dependence of the electrical conductivity σ , the Hall coefficient R and the thermopower coefficient α in the solid solutions $TlIn_{1-x}Yb_xTe_2$ (0 ≤ x ≤0.10) have been investigated in the temperature range of 80-1000 K. The effective masses of electrons and holes have been determined on the basis of the kinetic parameters. It was established that starting from x = 0.05 the solid solutions of TlIn_{1-x}Yb_xTe₂ belong to narrow-gap semiconductors having high values of the interaction matrix element. It is shown that the samples of $TlIn_{1-x}Yb_xTe_2$ in the region of 0.10 ≥ x ≥ 0.05 are promising materials for the energy converters operating at high temperatures.

Opis:
The metallic behavior of the band gap of intermetallic compounds has large applications in superconductivity, nickel-metal hydrides batteries, semiconductors, and heating materials. The presence of transition elements makes them more attractive for magnetic applications. In this work we studied the structural, electronic, chemical bonding, and magnetic properties of binary intermetallic compounds $XY_3$ (X = Al, Ga and Y = V, Nb, Cr, Mo). These compounds were investigated by using full potential linearized augmented plane wave plus local orbitals method. The exchange correlation potential of generalized gradient is used. Our calculated lattice constants are in good agreement with experimental values. The band structures of these compounds are purely overlapping across the Fermi level. The bonding is mainly covalent in these compounds. The density of states of the compounds shows that the major contribution arises from d-states of anions. The investigation carried out shows that the most of these compounds have ferromagnetic nature, while few are diamagnetic. On the basis of this study it is expected that these compounds can be used as a best moulds for future study on similar compounds.

We present first-principles calculations of the structural and lattice-dynamical properties for cubic yttrium nitride. The ground state properties, such as the lattice constant and the bulk modulus, are calculated using a plane wave pseudopotential method within density functional theory. A linear-response approach to density functional theory is used to derive the phonon frequencies. In this work, we present plane-wave pseudopotential calculations within density functional theory and calculate the phonon frequencies for high symmetry points.

The precise knowledge of vibrational spectra would allow detecting small amounts of these materials by means of spectroscopic methods. The results of the investigation of the vibrational spectra of trinitrotoluene and 2,4,6-trinitrophenol molecules were published in our previous paper, where we investigated the normal state of the molecules. In this paper we present the investigation results of the trinitrotoluene and trinitrophenol molecules conformer's with $C_1$ and Cs symmetry. We analyzed the potential surfaces and vibration spectra by means of ab initio quantum chemical calculations using basis of Gaussian functions and GAMESS package. Calculations were performed at the Hartree-Fock level and with account of the electron correlation. Personal computers clusters necessary for such investigations were made and SCore parallel environment was used.

A direct method and ab initio force constants were used to calculate phonon dispersion curves and phonon density in Al. The force constants were determined from the Hellmann-Feynman forces induced by the displacement of an atom in the 2×2×2 fcc crystallographic supercell. This size of the supercell gives exact phonon frequencies at Γ, X, L, W points of the Brillouin zone. The calculated phonon dispersion curves are in good agreement with the experimental data.

We studied the electronic, magnetic and transport properties of the hexagonal YCo$\text{}_{3}$B$\text{}_{2}$ compound. The electronic structure was studied by X-ray photoemission spectroscopy and ab initio self-consistent tight binding linear muffin tin orbital method. We found a good agreement between the experimental X-ray photoemission spectroscopy valence band spectra and theoretical calculations. Theoretical calculations showed that the YCo$\text{}_{3}$B$\text{}_{2}$ is a paramagnet in agreement with experimental results. Electrical resistivity at low temperatures shows a T$\text{}^{2}$ dependence, implying that the scattering by the spin fluctuactions is dominant in this temperature range.

Opis:
An extension of deformationally self-consistent approach to a quantitative analysis of adiabatic and nonadiabatic effects in vibration-rotational spectra of diatomic molecules is presented. We consider vibrational displacements of nuclei in the vicinity of dynamical reference conformation R$\text{}_{vJ}$ that depends not only on the rotational quantum number J through the action of centrifugal force, but also on the vibrational v one, through nonadiabatic vibrational effects of high order. The method is applied to LiH X$\text{}^{1}$Σ$\text{}^{+}$; reported wave numbers of transitions are reproduced with σ̂=1.090 and F=5.98×10$\text{}^{14}$ using 14 independently adjusted parameters and 14 constrained parameters t$\text{}_{i=0-6}^{Li,H}$, representing nonadiabatic rotational effects. The latter have been evaluated from the rotational g-factor and electric dipole moment of LiH, both electronically computed.
