Opis:
A review is presented of the anomalous magnetic and superconducting properties of the heavy-fermion compound UPt$\text{}_{3}$ that has been a subject of extensive study during the past twenty years. The normal-state and superconducting properties of the compound were evaluated from magnetic, transport, and thermodynamic studies. In addition, neutron-diff raction and muon spin relaxation experiments were performed in the normal and superconducting states. The compound is characterized by a multiple superconducting phase diagram and by the coexistence of superconductivity and short-range antiferromagnetic interactions with quasi-static moments of the order of 10$\text{}^{-2}$μ$\text{}_{B}$/U-atom. Upon substituting Pt by Pd, the short-range magnetic interactions give way to long-range antiferromagnetic order with a maximal ordering temperature of 6 K for the 5 at.% Pd alloy and a magnetic moment of 0.6μ$\text{}_{B}$/U-atom. Superconductivity and long-range antiferromagnetic order are in competition resulting in a critical composition of 0.6 at.% Pd. At this concentration, non-Fermi liquid behaviour is observed.

Opis:
TOF mass spectrometer for research of third-harmonic generation effect in isotropic media was used. The nonlinear medium in the experiment was Xe gas, the incident beam had the wavelength of 3546 Ǻ and the generated radiation had the wavelength of 1182 Ǻ. A measure for the intensity of generated VUV was the intensity of the ion current generated at the spot where a non-homogeneous effusive molecular (2,2-dimethylbutane) beam was crossed by the VUV beam. The influence of parameters like the diameter of the UV beam and the Xe pressure on the VUV generation process was examined. The third-larmonic generation theory was used to verify the mass spectrometric data.

Opis:
Transverse magnetoresistivity (H ∥ [001]; and current ∥ [110]) of U$\text{}_{3}$As$\text{}_{4}$ has been measured in field up to 35 T. An abrupt change of the magnetoresistivity behaviour from saturated (low field) to unsaturated (high field) type was observed at the spin reorientational transition (19.1 T at 4.2 K). The transition is accompanied by a peak in the magnetoresistivity. The behaviour is ascribed to fractional spin polarization of the band electrons.

Opis:
St. Thomas Aquinas did not actually take the subject of patriotism in his deliberations. However, in Summa theologiae he discussed the virtue of piety, which is expressed in love, and estimates love for one’s parents and one’s homeland. Thus, it can be concluded that for Thomas piety is patriotism. In the twentieth century, some followers of Aquinas undertook thoughts about patriotism. Significant studies of this topic are the texts of J.M. Bocheński and J. Woroniecki. In their texts they discuss such issues as: the essence of patriotism, patriotic education, difference between patriotism and chauvinism or nationalism. Woroniecki believed that the family is the first school of patriotism. Bocheński however, while developing the concept of patriotism in Woroniecki’s approach, focuses on the issue of education of a patriotic attitude. For this reason, in the educational process, he takes human powers: intellect, will and senses, into account and gives specific suggestions for their „cultivation”.

A discussion of the C(T) data obtained on single-crystalline samples of Er123O$\text{}_{7-x}$ and Sm123O$\text{}_{7-x}$ compounds in applied magnetic fields for better evaluation of the crystal-electric-field parameters is given. The C(T) measurements of Sr-substituted compounds RBaSrCu$\text{}_{3}$O$\text{}_{7}$ revealed the λ-type of peak related to the antiferromagnetic order at 1.2 K and 0.6 K respectively for Dy- and Er-compounds. The magnetic singlet ground state in these compounds is produced by weak exchange interactions of -0.05 T/μ$\text{}_{B}$ and -0.035 T/μ$\text{}_{B}$, respectively. For Nd- and Sm-compounds, only a broad anomaly around 0.6 K was observed which is well fitted with a Schottky-type anomaly with an energy splitting of 1.4 K.

Opis:
The large effluxes generated by high-tech plasmas force plasmas to non-equilibrium conditions. This implies that plasma features are decoupled from each other and that therefore different methods have to be used quasi-simultaneously to characterize the plasma. Even more insight in plasmas and methods is obtained if polydiagnostics is applied to a series of plasma conditions that gradually differ in equilibrium departure. After discussing methods of passive and active spectroscopy, we apply polydiagnostics on an argon plasma operated in open air. By introducing H2 and reducing the power we approach conditions of cool atmospheric plasmas (CAPs). It is seen that especially the passive methods for the electron temperature determination are very sensitive to the degree of equilibrium departure suggesting that active spectroscopy is preferable. However, one should realize that lasers can easily heat cool plasmas. This is due to the fact that the ionization degree of (semi-) CAPs is small.

Opis:
Although smallpox was eradicated over 30 years ago, the disease remains a major threat. High mortality, high infectivity and low resistance of the contemporary population make the smallpox virus very attractive to terrorists. The possible presence of illegal stocks of the virus or risk of deliberate genetic modifications cause serious concerns among experts. Hence, it is reasonable to seek effective drugs that could be used in case of smallpox outbreak. This paper reviews studies on compounds with proven in vitro or in vivo antipoxviruses potential, which show various mechanisms of action. Nucleoside analogues, such as cidofovir, can inhibit virus replication. Cidofovir derivatives are developed to improve the bioavailability of the drug. Among the nucleoside analogues under current investigation are: ANO (adenozine N1-oxide) and its derivatives, N-methanocarbothymidine [(N)-MCT], or derivatitives of aciklovir, peninclovir and brivudin. Recently, ST-246 – which effectively inhibits infection by limiting release of progeny virions – has become an object of attention. It has been also been demonstrated that compounds such as: nigericin, aptamers and peptides may have antiviral potential. An interesting strategy to fight infections was presented in experiments aimed at defining the role of individual genes (E3L, K3L or C6L) in the pathogenesis, and looking for their potential blockers. Additionally, among substances considered to be effective in the treatment of smallpox cases, there are factors that can block viral inhibitors of the human complement system, epidermal growth factor inhibitors or immunomodulators. Further studies on compounds with activity against poxviruses are necessary in order to broaden the pool of available means that could be used in the case of a new outbreak of smallpox.

Opis:
Legumes should be considered as an important part of a healthy diet, because of both their nutritional value (high protein and low fat content) and functional properties (Trichopoulou et al. 2014). The functional components include carbohydrates, soluble fiber, vitamins and polyphenols. Epidemiological studies have shown a positive correlation between the consumption of legumes and a reduced risk of cardiovascular diseases, diabetes and certain types of cancer. In the past few years, phenolic compounds have attracted much attention owing to a large variety of biological actions, including anti-inflammatory effects, which they can produce (García-Lafuente et al. 2014). Chronic inflammation is a cause of many serious diseases, including cardiac disorders, allergy, DM 1, Alzheimer’s disease. In the anti-inflammatory food pyramid, pulses were placed at the base (Viveky et al. 2013). The aim of this study was to determine the content of amino acids, fatty acids, carbohydrates, macro- and micro-elements in the common legumes. The total protein content varied from 17.9 to 22.5 g 100 g-1. The mean content of fat varied from 1.1 to 2.0 g 100 g-1 and the soluble sugar content ranged from 4.3 to 7.9 g 100 g-1. The dominant amino acids were glutamic and aspartic acids. Methionine and cysteine composed the lowest percentage of all amino acids. Pulses were characterized by the presence of such fatty acids as a-linoleic, linoleic, oleic and palmitic acid. The mean content of iron varied from 3.3 to 5.3 g 100 g-1. The highest amount of this element was found in small bean, which was also characterized by the highest copper content. The highest amounts of zinc, calcium and magnesium were contained in dark red kidney bean. The analyzed pulses were distinguishd by high nutritive value. The identifed amino acids profile indicates sufficient quantity of lysine and shortage of sulphuric acids. The pulses also had a beneficial composition of fatty acids. The omega-6 to omega-3 ratio was between 1:2 and 4:1.

Opis:
Viral hemorrhagic fevers are severe zoonotic diseases caused by RNA-viruses classified into 4 families: Arenaviridae, Bunyaviridae, Filoviridae, and Flaviviridae. They are present on all continents except Antarctica, their person-to-person spread is easy, and there is a high risk of them being used as weapon by bioterrorists. So far, efforts to develop effective drugs against these viruses have failed, and typical therapy usually relies on symptomatic treatment. Search for substances that could effectively inhibit this type of infections is now a priority. The presented paper gives an overview of different approaches used in combating the viral hemorrhagic fevers. Researchers look for safe antiviral agents with appropriate properties among natural sources, such as various types of herbs plants, algae, or essential oils obtained from trees, as well as investigate the use of various synthetic substances. The aim is to broaden the pool of available antiviral drugs that could replace hitherto applied medicines such as ribavirin, which is not always sufficiently effective and may have side-effects. The scientists focus not only on combating the diseases, but also on their prevention. For this purpose, recombinant vaccines or various types of immunomodulators may serve as a useful tools. Results of the latest studies are promising and encourage further work which may eventually lead to the solution of the urgent problem of hemorrhagic fevers.

Opis:
Gallium nitride bulk crystals grown at about 15 kbar and 1500 K have been examined by using the high resolution X-ray diffractometry. An analysis of a set of the rocking curves of various Bragg reflections enabled us to estimate a dislocation density. For the crystals of dimensions lower than about 1 mm it is lower than 10$\text{}^{-5}$ cm$\text{}^{-2}$. For bigger samples the crystallographic quality worsens. With an application of the reciprocal lattice mapping we could distinguish between internal strains and mosaicity which are both present in these crystals The results for the bulk crystals are compared with those for epitaxial layers.

Opis:
Two high latitude fjords of Spitsbergen (Hornsund 77°N and Kongsfjorden 79°N) are regarded as being highly productive (70 g and 50 gC m−2 year−1) and having organic-rich sediments. Hornsund has more organic matter in its sediments (8%), nearly half of it of terrestrial origin, while most of that in Kongsfjorden (5%) comes from fresh, marine sources (microplankton). Analysis of the carbon sources in both fjords shows that a major difference is the much larger seabird population in Hornsund-dominated with over 100 thousands pairs of plankton feeding little auks in Hornsund versus 2 thousand pairs in Kongsfjorden, and marine food consumption estimated as 5573 tonnes of carbon in Hornsund, versus 3047 tonnes in Kongsfjorden during one month of chick feeding period. Seabird colonies supply rich ornithogenic tundra (595 tonnes of C, as against only 266 tonnes of C in the Kongsfjorden tundra). No much of the terrestrial carbon, flushed out or wind-blown to the fjord, is consumed on the seabed – a state of affairs that is reflected by the low metabolic activity of bacteria and benthos and the lower benthic biomass in Hornsund than in Kongsfjorden.

Radars with continuous wave frequency (CW FM sonars) are used in radiolocation as ‘silent radars’. They determine the distance to target by measuring the difference between the frequency of the sounding signal and echo signal. The article presents the principle of operation and parameters of silent CW FM sonars. Target distance determined by these sonars is based on the signal at the output of the matched filter. The Doppler effect is studied in detail to identify its effect on the sonar’s parameters. The results of theoretical calculations are presented together with the results of the sonar’s computer simulation.

Opis:
Contemporary human diet contains excessive quantities of n-6 saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA), but it is deficient in n-3 fatty acids. This imbalance could be the cause of respiratory diseases, obesity and cancer. until recently, animal fat, including meat fat, was regarded solely as a source of saturated fatty acids, which are a risk factor for atherosclerosis, obesity and certain types of cancer. Recent studies have shown, however, that animal fats contain biologically active substances beneficial for health, and that only some saturated fatty acids have adverse consequences. The latter group includes lauric acid (C12), myristic acid (C14) and palmitic acid (C16), i.e. mainly the ones with an unfavorable n-6/n-3 fatty acid ratio. Apart from fat, beef also contains high amounts of minerals, mainly phosphorus, potassium, magnesium and zinc. Conjugated linoleic acid (CLA), in particular its cis-9 trans-11 and trans-9 cis-11 isomers, is one of the substances with health-supporting properties. Synthesized solely in the gastrointestinal tract of ruminants, CLA reaches the blood stream and is used by the mammary gland to synthesize milk fat. CLA is embedded in the animal's adipose tissue. There is a large body of research confirming CLA's ability to reduce the risk of atherosclerosis and obesity, and to lower cholesterol levels. when incorporated into the human diet in the amount of 1.5 to 3.5 g, CLA exerts anticarcinogenic effects (it inhibits the development ofbreast cancer, malignant melanoma, colorectal cancer and lung cancer). CLA prevents and alleviates the symptoms of type 2 diabetes; it is a powerful antioxidant and it boosts immunity. The highest quantities of CLA have been noted in the meat of ruminants. The CLA content of ruminant meat has been determined in the range of 10 to 33 mg 100 g- 1 of fat, being much higher than in pork (2-19 mg) and poultry (3.4 mg). Beef also has the most desirable n-6/n-3 fatty acid ratio at 6.3:1 in comparison with pork (12.7:1) and poultry (8.3:1). The highest levels of n-3 fatty acids can also be found in beef (5-6 g in 100 g fat). The objective of this study was to present and discuss the most recent findings concerning the fatty acid content of beef and its implications for human health. Source data were gathered and grouped thematically, and an attempt was made to characterize beef and its fatty acid profile.
Dieta współczesnego człowieka zawiera zbyt dużo kwasów nasyconych (SFA-saturated fatty acid) i wielonienasyconych (PUFA-polly unsaturated fatty acid) typu n-6, a zbyt mało typu n-3, co jest przyczyną m.in. chorób związanych z układem krążenia, otyłością, a także chorobą nowotworową. Do niedawna tłuszcz zwierzęcy, w tym tłuszcz mięsa, był postrzegany jedynie jako źródło niekorzystnych dla człowieka nasyconych kwasów tłuszczowych powodujących miażdżycę, otyłość i niektóre nowotwory. Tymczasem, jak wykazują badania ostatnich lat, tłuszcze zwierzęce zawierają substancje biologicznie czynne o charakterze prozdrowotnym, a niebezpieczne dla zdrowia człowieka są jedynie niektóre kwasy nasycone (laurynowy C12), mirystynowy (C14) oraz palmitynowy C16), a głównie te, które występują w niewłaściwej proporcji, rodziny kwasów n-6 do n-3. Mięso wołowe zawiera także znaczne ilości składników mineralnych, zwłaszcza fosforu, potasu, magnezu oraz cynku. Celem pracy było zebranie najnowszej literatury dotyczącej wpływu kwasów tłuszczowych znajdujących się w mięsie wołowym na zdrowie ludzi w aspekcie jej prozdrowotnych właściwości. W tym celu zgromadzono i pogrupowano tematycznie dostępną na ten temat literaturę oraz dokonano próby opisu charakteryzującego mięso wołowe i zawartych w nim kwasów tłuszczowych. Jedną z substancji o działaniu prozdrowotnym jest sprzężony kwas linolowy (CLA-conjugated linoleic acid), powstający wyłącznie w przewodzie pokarmowym przeżuwaczy (stąd trafia do krwi, a dalej wykorzystywany jest przez gruczoł mleczny do syntezy tłuszczu mleka oraz wbudowany jest w tkankę tłuszczową zwierzęcia), a szczególnie jego izomery cis-9 trans-11 i trans-9 cis-11. Wiele badań potwierdza jego działanie antymiażdżycowe i przeciwdziałające otyłości, a także ograniczające zawartość cholesterolu. Zawartość CLA od 1,5 do 3,5 g w diecie człowieka ma działanie antynowotworowe (hamuje rozwój raka sutka, czerniaka złośliwego, raka jelita grubego oraz raka płuc). Ponadto CLA jest czynnikiem zapobiegającym i łagodzącym objawy cukrzycy insulinozależnej II typu, ma działanie antyoksydacyjne jako silny przeciwutleniacz, a także wykazuje dodatni wpływ na funkcje układu odpornościowego. Najwięcej kwasu CLA zawiera mięso zwierząt przeżuwających - od 10 do 33 mg CLA, mięso wieprzowe 2-19 mg CLA, a drobiowe 3,4 mg CLA w 100 g tłuszczu. Mięso wołowe ma również najkorzystniejszy stosunek kwasów n-6 do n-3, który wynosi 6,3:1, podczas gdy w mięsie wieprzowym 12,7:1, a drobiowym 8,3:1. W mięsie wołowym stwierdzono również najwyższą zawartość kwasów z grupy n-3 (od 5 do 6 g w 100 g tłuszczu).

Opis:
In this paper, the analysis of generalized multicomplex Mandelbrot-Julia (henceforth abbrev. M-J) sets is performed in terms of their shape when a degree of an iterated polynomial tends to infinity. Since the multicomplex algebras result from a tensor product of complex algebras, the dynamics of multicomplex systems described by iterated polynomials is different with respect to their complex and hypercomplex analogues. When the degree of an iterated polynomial tends to infinity the M-J sets tend to the higher dimensional generalization of the Steinmetz solid, depending on the dimension of a vector space, where a given generalization of M-J sets is constructed. The paper describes a case of bicomplex M-J sets with appropriate visualizations as well as a tricomplex one, and the most general case - the muticomplex M-J sets, and their corresponding geometrical convergents.

Opis:
Radiostrontium 85Sr sorption experiments were carried out at 4°C and 20°C using natural samples of the epiphytic foliose lichen Hypogymnia physodes. Thalli were incubated in water solutions containing 10 5 to 10 1 mol.l 1 SrCl2 for up to 24 h at the initial pH 5.5. Sorption equilibrium at 4°C and 20°C was observed within 1 hour and did not change within the next 24 hours. Sorption process can be described well by Freundlich adsorption isotherm in both linearised and non-linearised form, not by Langmuir adsorption isotherm. Inactivation of lichen biomass by formaldehyde or temperature pretreatment did not cause loss of biosorption activity. 85Sr biosorption was strongly pH dependent increased from negligible values at pH 2 up to nearly 100% uptake at pH 5.5. Bivalent cations Me2+ act as competitors for 85Sr biosorption with the competition effect increasing in the order Co < Mg < Ca < Cd < Ni < Ba < Zn < Cu for Me2+ concentration 0.01 mol.l 1. A number of displacing agents have been tested for their ability to release extracellular bound 85Sr2+ ions from Hypogymnia physodes. Displacing efficiency increases in the order: water <<< EDTA (acid) < NaHCO3 < Na2EDTA < oxalic acid < BaCl2 < MgCl2 < CaCl2 < SrCl2. Efficiency of strontium biosorption by different lichen taxa will reveal their role in fixation of radiostrontium contamination in biosphere.

Opis:
We have investigated the effect of hydrostatic pressure on magnetic properties of TbNiAl, crystallizing in hexagonal ZrNiAl-type structure. TbNiAl orders antiferromagnetically below $T_{N}$=45 K and undergoes further magnetic phase transition to another AF phase at $T_{1}$=23 K. The magnetic field of $B_{c}$ ≅ 0.3 T applied along the c-axis at 2 K leads to the transition to ferromagnetic order. By applying the hydrostatic pressure, both $T_{N}$ and $T_{1}$ remain almost unaffected whereas $B_{c}$ shows a strong increase. The hydrostatic pressure stabilizes the antiferromagnetic state which can be related to development of structural parameters.

Opis:
The association between physiologically dependent pharmacokinetic parameters (CLB, T1/2β, Vdss) of marbofloxacin and body weight was studied in eight animal species based on allometric equation Y = aWb, where ‘Y’ is the pharmacokinetic parameter, ‘W’ is body weight, ‘a’ is allometric coefficient (intercept) and ‘b’ is the exponent that describes relation between pharmacokinetic parameter and body weight. The body clearance of marbofloxacin has shown significant (P<0.0001) relation with size (Bwt) in various animal species. However, half-life and volume of distribution were not in association with body weight. Although half-life and volume of distribution were not in a good correlation with body weight, statistically significant association between the body clearance and body weight suggests validity of allometric scaling for predicting pharmacokinetic parameters of marbofloxacin in animal species that have not been studied yet. However further study considering large sample size and other parameters influencing pharmacokinetics of marbofloxacin is recommended.

Opis:
Electromagnetic pollution generated by the electrical devices has been regarded as a new form of pollution, harmful to the society as air and water pollution. The operation of electronic devices in a polluted electromagnetic environment has caused electromagnetic interference to become important concerns. Devices that are vulnerable to interference must often be shielded to protect them from the effects of electromagnetic interference. In this work we describe an interaction of a magnetic fluid based on transformer oil with alternating magnetic field. The magnetic fluid was composed of a transformer oil and dispersed magnetite nanoparticles coated with oleic acid. Among the wide range of topics covered, we pay attention to an important field related to the absorption of electromagnetic field by magnetic fluid as a suitable candidate for applications where it is necessary to electrically isolate, remove excess of heat, and to shield electromagnetic fields. We present a method for the determination of shielding effectiveness of the magnetic fluid under high-frequency excitation conditions from 750 MHz to 3 GHz by means of magnetic near field measurements and analysis. Herein, we report the effect of magnetic volume fraction in the magnetic fluid and the effect of the sample thickness on the shielding effectiveness. We have found that the magnetic fluid has a frequency dependent "windows", characterized that either absorb the magnetic field, or facilitate penetration of the magnetic field through the barrier.

Opis:
Recently a new wave of interest in physics of RCo₂ compounds has been boosted by reports on unusual magnetic short range order configurations in the heavy rare-earth RCo₂ ferrimagnets in paramagnetic state. The newly observed phenomenon called parimagnetism consists in a short-range antiferromagnetic coupling between small ferromagnetic Co clusters and the nearest rare-earth moments. This paper is devoted to results of our experimental investigation of carefully prepared and characterized samples of TmCo₂, a compound on which controversial results can be found in literature. Detailed magnetization, AC susceptibility, specific heat and electrical resistivity measurements revealed two magnetic phase transitions at 4.6 and 3.6 K, respectively. The anomalies connected with the transitions are strongly dependent on magnetic field and hydrostatic pressure. The AC susceptibility anomaly connected with the onset of parimagnetism has been found at $T_{f}$=35 K. Contrary to other heavy rare-earth RCo₂ counterparts $T_{f}$ of TmCo₂ is entirely pressure independent.

Opis:
Zofia Kaczorowska was born on 11 September 1902 in Warsaw. She finished secondary school in 1921. Then, in 1924 she started studying at the Faculty of Mathematics and Natural Sciences of the University of Warsaw. At the same time she worked at the State Meteorological Institute. In 1928 she was granted a scholarship from the Institute, with the obligation of specialising in the domain of meteorology. In 1932 Zofia Kaczorowska obtained the title of doctor of philosophy on the basis of the publication entitled Meteorological causes of the summer swells of Vistula river (in Polish) and took up the work in the Climatological Department of the State Meteorological Institute, where she stayed until the outbreak of the World War II. During the academic year 1938/1939 she was also a research assistant in the Department of Meteorology and Climatology of the Warsaw University of the Life Sciences. Assistant professor Zofia Kaczorowska produced a significant scientific output, despite the objective difficulties in the maintenance of continuity of the research work caused by her long illness, the period of war, and the very intensive teaching work. She made a very valuable contribution to the education and schooling of the young geographers, and especially of the climatologists, for whom she conducted during twenty years the courses in: meteorology for the students of the Ist year of geography, and climatology for the IInd year, in the climate of Poland for the students of the IVth year, specialising in physical geography, as well as in elements of meteorology and climatology for the students of geology specialising in the Quaternary. She was in charge of the Master's seminars and workshops for the students of the climatological specialisation. She was also very active in field exercises and entry examinations. The attitude of Zofia Kaczorowska with respect to students was always very cordial, and she would especially take care of those who were in need. The ancient and the current employees of the Department of Climatology of the Faculty of Geography and Regional Studies, University of Warsaw, her pupils and associates, paid homage to Zofia Kaczorowska during her funeral in February 1993 (she passed away on 11 Febuary 1993 in Warsaw).

Opis:
The review process is intended to provide an objective assessment of the suitability of a submission to the target journal. When authors receive the decision letter from the editor it is almost always accompanied with the reviews, which at times can be quite critical. Writing a well-constructed response letter to the reviewers, with well-reasoned arguments, is a key part of the reviewing process. Although the manuscript is the main focus of the submission, the content and tone of the response letter can have a surprisingly large impact on the eventual recommendation given by the reviewers. The importance of writing a clear response letter is often overlooked by authors. This prompted us to prepare a short article addressing the main points that can help authors prepare their response to reviewer letter to the reviewers. Although each review is unique, here, we outline ten points which are aimed at helping authors respond effectively and clearly to reviewers’ comments. The points are based on the authors’ collective experiences which includes publishing and reviewing for international peer-reviewed journals. The tone of the letter should always be professional, organized and objective. Each point raised by the reviewers needs to be replied to in a precise way, with clear evidence that the major concerns have been considered in a serious way. This article also covers what information should be included, when it is appropriate to disagree with a reviewer, and how to present appropriate rebuttals.

Opis:
Mary Wollstonecraft i Jean-Jacques Rousseau, jako przedstawiciele Oświecenia, oboje poświęcili swoje dzieła wychowaniu. Wollstonecraft w rozprawie Wołanie o prawa kobiety wielokrotnie odnosiła się do ogólnej koncepcji płci oraz kobiecości zawartych w Emilu, czyli o wychowaniu Rousseau. W powieści tej francuski filozof opisał, jak powinno wychowywać się jednostki w duchu naturalizmu. Kolejne etapy rozwoju Emila wieńczy jego wejście w okres dojrzałości, kiedy to spotyka swą wybrankę Zofię i jest gotów do założenia własnej rodziny. Rousseau opisał Zofię jako skromną, niewyedukowaną kobietę, której głównym zadaniem jest podobać się swemu przyszłemu mężowi. Tę wizję kobiecości skrupulatnie krytykuje Wollstonecraft. Podważa ona przesądy o „kobiecej naturze” oraz postuluje otwarcie koedukacyjnych szkół. Argumentuje też za taką samą edukacją dla dziewczynek jak dla chłopców, widząc w tym sposób na poprawę losu kobiet w społeczeństwie, przez co społeczeństwo może tylko zyskać. Prócz tego wprowadza pojęcie patriotycznego macierzyństwa. Artykuł przedstawia stanowiska obojga filozofów oraz wskazuje na podstawowe różnice między ich poglądami. Dodatkowo umieszcza twórczość Wollstonecraft w szerszym kontekście feministycznym.

Opis:
Background. Bread is one of the world’s most consumed food commodity. However, in the last years consumption of bread and bakery products has declined, especially in the Western population. The reason for concern is the weight gain and presence of gluten in these products. Gluten is unacceptable in the diet only in patients with celiac disease who are forced adhere the gluten-free diet all the time. The consequences of gluten-free diet in healthy people are the subject of many recent studies. Objective. The aim of this study was to evaluate the changes of visceral fat area in the general population after 6 weeks of consumption of gluten-free, gluten-containing and whole-grain bread and other bakery products. Material and Methods. The study group consisted of 120 volunteers divided into four subgroups each with 30 subjects. Anthropometric measurements were made using the InBody 720 (Biospace Co. Ltd., Seoul, Republic of Korea). We used the Lookin’Body 3.0 software to process the results. The collected data from anthropometric measurements were evaluated statistically and graphically in Microsoft Office Excel 2010 (Los Angeles, CA, USA). Results. After the intervention we found out that visceral fat area values increased in probands consuming gluten-free and gluten-containing bakery products, but these changes were not significant (P>0.05; 72.7±29.18 cm2 vs 73.26±30.32 cm2 and 69.6±34.06 cm2 vs 70.34±32.33 cm2, respectively). In whole-grain and control group we observed a reduction in visceral fat area, in the control group there was a significant change (P>0.05 – 91.58±33 cm2 vs 90.47±34.37 cm2 and P<0.05 – 77.3±21.65 cm2 vs 75.56±21.87 cm2, respectively). After the intervention the visceral fat area values increased in gluten-free group in 57% of subjects, in gluten group in 73% of subjects and in the whole-grain group in 43% of volunteers. Although visceral fat area values had inceased in gluten-free and gluten-containing groups, the number of probands with reference values increased from 80% to 86% in the gluten-free group and from 43% to 66% in the gluten-containing group. In the whole-grain group we found decrease in number of subjects with reference values of visceral fat area (from 70% to 63%). There were no changes in the control group (86% vs. 86%). Conclusions. Consumption of different types of bakery products has mostly changed the visceral fat area values in a positive direction.
Wstęp. Chleb jest jednym z najczęściej spożywanych produktów żywnościowych na świecie. Jednak w ostatnich latach spadło spożycie pieczywa, zwłaszcza w populacji zachodniej. Powodem rezygnacji z konsumpcji jest obawa o przyrost masy ciała i obecność glutenu w tych produktach. Gluten jest niedopuszczalny w diecie tylko u pacjentów z celiakią, którzy są zmuszeni stosować dietę bezglutenową. Konsekwencje stosowania diety bezglutenowej u zdrowych ludzi są przedmiotem wielu ostatnich badań. Cel. Celem badania była ocena zmian w obszarze trzewnej tkanki tłuszczowej w grupie badanej po 6 tygodniach konsumpcji: chleba bezglutenowego, chleba zawierającego gluten i chleba pełnoziarnistego oraz innych produktów piekarniczych. Materiał i metody. Grupa badana składała się ze 120 ochotników podzielonych na cztery podgrupy, w każdej po 30 osób. Pomiary antropometryczne wykonano przy użyciu InBody 720 (Biospace Co. Ltd., Seoul, Republika Korei). Do analizy wyników wykorzystano oprogramowanie Lookin’Body 3.0. Zebrane dane z pomiarów antropometrycznych zostały ocenione statystycznie i graficznie w Microsoft Office Excel 2010 (Los Angeles, Kalifornia, USA). Wyniki. Po interwencji dietetycznej wykazano, że wartości trzewnej tkanki tłuszczowej wzrosły u osób spożywających produkty piekarnicze bezglutenowe i zawierające gluten, ale zmiany te nie były istotne statystycznie (p> 0,05, 72,7 ± 29,18 cm2 w porównaniu z 73,26 ± 30,32 cm2 i 69,6 ± 34,06 cm2 vs 70.34 ± 32,33 cm2, odpowiednio). W grupie osób spożywających chleb pełnoziarnisty i kontrolnej obserwowano zmniejszenie trzewnej tkanki tłuszczowej, w grupie kontrolnej nastąpiła istotna zmiana (p> 0,05 - 91,58 ± 33 cm2 wobec 90,47 ± 34,37 cm2 i p <0,05 - 77,3 ± 21,65 cm2 vs 75,56 ± 21,87 cm2, odpowiednio). Po interwencji dietetycznej wartości trzewnej tkanki tłuszczowej zwiększyły się w grupie spożywającej chleb bezglutenowy u 57% badanych, w grupie spożywającej chleb z glutenem u 73% badanych oraz w grupie osób spożywającej chleb pełnoziarnisty u 43% ochotników. Chociaż wartości trzewnej tkanki tłuszczowej były obecne w grupach osób spożywających chleb bez glutenu i zawierających gluten, liczba uczestników o wartościach referencyjnych prawidłowych wzrosła z 80% do 86% w grupie bezglutenowej i z 43% do 66% w grupie zawierającej gluten. W grupie osób spożywających chleb z pełnymi ziarnami stwierdzono zmniejszenie liczby osób z wartościami referencyjnymi prawidłowymi trzewnej tkanki tłuszczowej (z 70% do 63%). W grupie kontrolnej nie zanotowano zmian (86% vs. 86%). Wnioski. Spożywanie różnych rodzajów produktów piekarniczych w większości zmieniło zawartość trzewnej tkanki tłuszczowej u osób poddanych badaniu.

Opis:
The lower Cambrian (Series 2) White Point Conglomerate (WPC) on Kangaroo Island, South Australia contains exotic clasts representing a diverse array of lithologies, including metamorphics, chert, sandstone, and abundant carbonates, notably archaeocyath-rich bioclastic limestone. Acetic acid digestion of the WPC bioclastic limestone clasts reveals a diverse shelly fauna. This assemblage includes abundant organophosphatic brachiopods such as Cordatia erinae Brock and Claybourn gen. et sp. nov., Curdus pararaensis, Eodicellomus elkaniformiis, Eohadrotreta sp. cf. E. zhenbaensis, Eoobolus sp., Kyrshabaktella davidii, and Schizopholis yorkensis. Additional shelly taxa include the solenopleurid trilobite Trachoparia? sp., the tommotiids Dailyatia odyssei, Dailyatia decobruta Betts sp. nov., Kelanella sp., and Lapworthella fasciculata, spines of the bradoriid arthropod Mongolitubulus squamifer, and several problematica, such as Stoibostrombus crenulatus and a variety of tubular forms. The upper age limit for the WPC is constrained by biostratigraphic data from the overlying Marsden Sandstone and Emu Bay Shale, which are no younger than the Pararaia janeae Trilobite Zone (Cambrian Series 2, Stage 4). The shelly fossil assemblage from the WPC limestone clasts indicates an upper Dailyatia odyssei Zone (= Pararaia tatei to lower P. janeae trilobite zones), equivalent to the Atdabanian–early Botoman of the Siberian scheme. This contrasts with the previously suggested late Botoman age for the limestone clasts, based on the diverse archaeocyath assemblage. The minor age difference between the WPC and its fossiliferous limestone clasts suggests relatively rapid reworking of biohermal buildups during tectonically-active phases of deposition in the Stansbury Basin.

The convectional drying of rectangular block of wet mortar was investigated with thermal neutron radiography technique supplemented with traditional mass and temperature measurements. The time evolution of the drying process was recorded for rectangular sample of aged mortar before and after painting its lateral sides. The receding boundary of the central core wet region was observed in the advanced stage of the process. The size, shape and water content of that region were determined for both cases of non-painted and painted sample. It was shown that in the advanced drying process the receding drying front exists irrespectively of the drying pattern observed at the early period of drying.

Opis:
In technical sciences, the term "machining" refers to the process of forming an object into a desired shape and size, with a desired quality of surface, by removing layers of its material by means of a cutting tool. The paper describes research on ultra-precision machining (UPM), where the abovementioned process takes place on the atomic level and involves systems (a machined object and a tool) several dozen nanometers in size. Three-dimensional computer simulations (virtual experiments) of UPM of monocrystalline copper with an infinitely hard tool were performed utilizing the classical molecular dynamics (MD) method with a many-body potential to describe the interatomic interactions. Among the examined issues were: the effect of the tool shape, machining speed and depth on the obtained workmaterial surfaces, and on the stresses, slip patterns and local temperature increases generated during the process.

Opis:
GaN crystals are grown using ammonothermal method at pressures below 5 kbar and temperatures below 550°C. In this method, GaN is synthesised from high purity metallic gallium. The main role in the low temperature GaN crystallization is played by the chemically active and dense ammonia and dissolved mineralizer. Morphology of the obtained crystals as well as solubility experiments prove that gallium nitride is dissolved and crystallised from solution. Physical properties of GaN crystals obtained using ammonothermal method depend on the growth conditions and the type of mineralizer. All GaN samples reveal very intensive photoluminescence, also at room temperature. The spectra of crystals grown with lithium compound mineralizer are shifted towards higher energies in comparison to crystals grown with potassium based mineralizer. At helium temperatures, phosphorescence is also observed.

Opis:
The intermetallic compound $PrCo_2Ge_2$ exhibits very interesting physical properties: antiferromagnetism below $T_N$ = 28 K, an order to order transition at $T_R$ = 8 K, a rich magnetic phase diagram, and huge magnetocrystalline anisotropy as observed by recent experiments on a single crystal in a magnetic field up to 14 T. We performed first principles calculations based on the density functional theory. The localized $4f^2$ configuration of $Pr^{3+}$ was treated using the open core approximation. The electronic densities of states were obtained and the position of the Fermi level was found. The hybridization between the Co-3d, Pr-5d and Ge-4p states is discussed. The calculated magnetic moment of Co is found to be quite small $(m_{Co} < 0.1 μ_B)$. The first principles calculations of the crystal field interaction were performed as well: the obtained crystal field parameters were used as the starting parameters for further refinement in comparison with experimental data of the magnetic susceptibility and specific heat. The crystal field splitting of the 4f states was determined.

Magnetite polycrystalline nanowires were characterized by means of X-ray diffraction and 57Fe Mössbauer spectroscopy (MS). The average length of these nanowires is about 70 nm and their diameter is about 3 nm. Mössbauer studies evidenced that the composites consist of very small Fe3O4 particles. Almost 80% of particles exist in a paramagnetic state.

Opis:
Five morphological types of hemocytes were recognized in hemolymph of the 4th instar larvae of Hyphantria cunea (Drury). These hemocytes were: prohemocytes, plasmotocytes, granulocytes, oenocytoids, and spherulocytes. Tests were done on the effects of four isolates of the entomopathogenic fungus Beauveria bassiana (Bals.-Criy) (Fashand, spt-22, Ir-K-40 and 566), one isolate of Isaria farinosae (Holmsk.) Fr. (1872c), and latex-beads on the cellular immune defense mechanism and Phenoloxidase (PO) activity of H. cunea. Observation showed that plasmatocytes and granulocytes engulfed fungal pathogens by phagocytosis. The most phagocytosis occurred 30 and 60 min after injection but nodulation occurred in 3 and 6 hours, in all treatments. The total hemocyte count (THC) and granulocyte, and plasmotocyte numbers increased after the injection of spores. Phenoloxidase activity was determined in the presence of L-DOPA (L-3,4-dihydroxyphenylalanine), as a substrate in intervals, after injection of fungal spores, and latex beads. These studies demonstrated that B. bassiana is a promising candidate for biological control of H. cunea.

Opis:
The growth process of cobalt on Ru(0001) was characterized by photoelectron spectroscopy excited by X-ray and synchrotron radiation. The binding energy position and intensity of the Co 2p$\text{}_{3}\text{}_{/}\text{}_{2}$ and Ru 3d$\text{}_{5}\text{}_{/}\text{}_{2}$ core levels as well as the shape and structure of the valence band spectra corresponding to the different stages of the deposition were investigated. An observed small positive binding energy shift is a consequence of an increase in the cobalt adatoms coordination number. The core-level shift between bulk and surface Ru atoms is determined as -360 meV. Upon adsorption of cobalt, the interface peak appears with a shift of -(70÷80) meV relative to the bulk one. On the basis of unchanged energy positions and widths of the Ru-derived features of the valence band spectra, a weak interaction between cobalt and substrate is suggested. The measured valence band could be reproduced by superimposing the spectra of the pure elements.

Opis:
Quail-thrushes (Passeriformes: Cinclosomatidae: Cinclosoma) are ground-dwelling corvoid songbirds endemic to Austra lia and New Guinea. Until now, the only known quail-thrush fossils have been from late Quaternary cave deposits in Australia. A new species of quail-thrush, Cinclosoma elachum sp. nov., is described from the early to middle Miocene deposits in the Riversleigh World Heritage Area, Queensland, Australia. A second, larger quail-thrush is identified from the middle Miocene of Riversleigh. The new fossils considerably extend the geographic and temporal ranges of cinclosomatids, and indicate the presence of two species of quail-thrushes in the Miocene of northern Australia, located more than 300 km from the nearest extant member of Cinclosoma. These fossils provide a minimum age of ~18 million years for Cinclosomatidae. They cannot be confidently assigned to the crown group of the genus Cinclosoma, but can be used to calibrate the split between this genus and Ptilorrhoa in molecular dating studies of the Corvides radiation and Passeriformes overall. This material also adds to the growing diversity of songbirds identified from the pre-Pleistocene record of Australia, and reemphasises the global significance of the Riversleigh deposits in developing understanding about the early evolutionary history of passerines.

Opis:
This article builds on the previous work and describes the interaction of transformer oil-based magnetic fluid (MF) with the radio frequency (RF) magnetic near-field. Three prepared samples of the MF used as a barrier to magnetic near-field, consist of transformer oil and dispersed magnetite nanoparticles coated with oleic acid. We pay attention to the important area related to the electromagnetic field shielding by the MF. Such sample of the MF may be a good candidate for applications where it is necessary to simultaneously electrically isolate, remove the excess of heat and to shield electromagnetic interference (EMI). We present a method for the determination of shielding effectiveness (SE) of the MF under RF excitation conditions ranging from 500 MHz to 3 GHz. We report the effect of magnetic volume fraction in the MF and the effect of the sample thickness on the SE.

Opis:
Initially, tobacco was considered as a decorative plant and only later began to be treated as a herb with special therapeutic properties. With time, it was found that tobacco had strong insecticidal and addictive properties. There also occurred reports about the negative influence of tobacco on human health. The World Health Organization (WHO) classifies smoking as a chronic, progressive disease which is also ‘contagious’. It is also considered to be a neurobiotic addiction. Nicotine addiction does not cause changes in the behaviour or functioning of a smoker; however, it adversely affects his or her general health status and the health status of people within their environment. Passive smoking (so-called ETS – Environmental Tobacco Smoke), which means accompanying smokers negatively influences the health of passive smokers. Environmental tobacco smoke, on the one hand, is the result of spontaneous cigarette burning and, on the other hand, the result of the side-stream of cigarette smoke, as well as the smoke exhaled by active smokers. Health personnel should clearly and convincingly present the data concerning the adverse results of smoking, as well as the dangers of exposure to environmental tobacco smoke, thereby making their patients aware that breaking their addiction will not only be beneficial for their own health, but will also protect non-smokers in their environment from the adverse effects of exposure to environmental tobacco smoke.

Opis:
The objective of this study was to evaluate the nitrification rate in soil polluted with zinc. The experimental protocol was as follows: soil (sandy loam) collected from the 0-20 cm layer of a cropped field was passed through a 2 mm mesh sieve, placed in 150 cm 3 glass beakers, 100 g of soil in each, and polluted with the following doses of Zn 2+ per 1 kg d.m. of soil: 0, 300, 600, 1 200 and 2 400. Zinc was applied in the form of ZnCl 2 aqueous solution. Afterwards, ammonia nitrogen as (NH 4 ) 2 SO 4 was added to the soil material in two doses: 0 and 240 mg N kg -1 d.m. Once zinc chloride and ammonium sulphate had been thoroughly mixed with the soil, water was added until the soil moisture content reached 50% of capillary water holding capacity and then the beakers were placed in a laboratory incubator at 25 o C. After 10, 20, 30 and 40 days, the incubated soil was tested to determine the content of N-NH 4 and N-NH 3 . Additionally, after 10 and 40 days of incubation, the most probable counts of nitrifying bacteria involved in the first and second step of the nitrification process were determined. The experiment was run with three replicates for each day. Two determinations of each parameter were performed in the soil samples placed in beakers. In total, 6 results were obtained for each experimental variant. Based on the determinations, the amounts of nitrified and immobilized nitrogen were calculated and the resistance (RS) and resilience (RL) of the nitrification process and nitrifying bacteria to the contamination of soil with zinc were expressed. It has been experimentally demonstrated that excess zinc in soil significantly disturbs the nitrification rate. As little as 300 mg Zn 2+ kg -1 d.m. of soil significantly inhibits nitrification. Zinc contamination interferes with nitrification and other metabolic process which affect soil nitrogen, which is confirmed by depressed nitrogen immobilization at higher rates of soil contamination with this element. The adverse effect of zinc on nitrification is primarily due to the negative impact of this element in the soil environment on nitrifying bacteria. Zinc more strongly inhibits the first than the second step nitrification bacteria, but ammonia-oxidizing bacteria recover more quickly than nitrate forms. The RS parameters for the nitrification process towards zinc pollution were on a low level and tended to decrease as the degree of zinc contamination rose. The resistance of nitrifying bacteria to zinc decreased parallel to the increasing amounts of zinc in soil.

Opis:
Summertime (2009), the third book of J.M. Coetzee’s autobiographical trilogy, is more poetic and more nostalgic in its depiction of South Africa than the writer’s previous works, though his vision remains sharp and unsentimental. Written from the perspective of an émigré writer, Summertime is an imaginative mapping of personal memories that reside in various places of South Africa, especially in the ruggedly beautiful landscapes of the Karoo region. For Coetzee, the Karoo is the site of the individual and collective historical past which he attempts to reconstruct and retain. The open spaces of the Karoo provide inspiration for his art and stimulate his search for new expressive means to represent African landscape, subverting the traditional colonialist topos of exoticism and wilderness. While in his first “Australian” novel, Slow Man (2005), Coetzee problematized the notion of ethno-cultural identity in an age of globalization and mass migration by presenting multicultural individuals whose destabilized identities defy categorizations of belonging and not belonging, in Summertime he emphasizes the crucial role of native landscape in the construction of self-identity, reveals his strong bond with his native country and portrays the Karoo as an anchoring space in a world of heterogeneity. Although, as Coetzee earlier confessed, South Africa is “a wound within him”, in Summertime reflective nostalgia allows the writer to come to terms with his native country and his past.

The literature analysed by REQUEST (REassesing QUinolone European STandard) using inclusion and exclusion criteria allows to make the conclusion that the proper use of fluoroquinolones (FQ) in canine colitis requires rigorously performed qualification to specific antimicrobial treatment. An infectious agent responsive to FQ therapy plays an integral role in the clinical manifestation of canine colitis, especially histiocytic ulcerative colitis (HUC) in young Boxer dogs. This supports the use of FQ in these cases. The Request guidelines for proper use of FQ in canine colitis is established, according to the available literature data.

The paper presents results of sintering proppants parameters and its influence on light ceramic proppants obtained by the mechanical granulation method. The proppants were prepared basing on a ceramic composition consisting of three raw materials such as kaolin, clay and bauxite mixed with poly(vinyl alcohol) binder with a molecular weight 26000 g/mol and hydrolysis degree of 88%, added in amount of 5 wt% with respect to the powder. Sintering temperature range oscillated between 1200 and 1225°C, kiln rotations were 1-2 rpm. Sintered proppants were characterized in compliance with PN-EN ISO 13503-2 norm and bulk density, sphericity coefficient, turbidity, solubility in acids and scanning electron microscopy observations have been estimated. The results demonstrated that sintering temperature and kiln rotation have an essential effect of the proppants parameters.

Wykazano brak istotnej interakcji między czynnikami doświadczenia, a istotnym okazał się tylko wpływ deszczowania i sposobów uprawy w działaniu niezależnym od siebie. Plony suchej masy średnio za 3 lata badań wynosiły dla łodyg 4,95 ton, liści 1,72 ton, strączyn 1,95 ton i masy korzeniowej 1,36 t·ha⁻¹. Oznacza to, że suma resztek pozbiorowych pozostawionych przez bobik wyniosła 9,98 t·ha⁻¹.
The purpose of the experiment carried out in years 1999 - 2001 on a lessive soil was to investigate the influence of sprinkling, cultivation system and nitrogen fertilization on the over-ground vegetative weight and root weight left by fababean. No significant interactions between experimental factors were found and the only significant impact was that of sprinkling irrigation and methods of cultivation, although these factors failed to interact with one another. Dry matter yields in the years of experiment averaged: 4.95 t for stems, 1.72 t for leaves, 1.95 t for stripped pods and 1.36 t·ha⁻¹ for root weight. This means that the total amount of post-harvest residues left by faba bean reached 9.98 t·ha⁻¹.

Opis:
Central Asia is a key area for crocodylomorph evolution, lying midway between the highly documented deposits in Europe and North America, but crocodylomorph fossils from this part of the world are rare. Included among these are specimens collected in the 1970s and 1980s by the Soviet-Mongolian Expeditions in the Jurassic and Cretaceous of Mongolia, Tajikistan, and Kazakhstan. Three species, “Sunosuchus” shartegensis, Kansajsuchus extensus, and Turanosuchus aralensis are redescribed and subjected to phylogenetic analysis for the first time. “Sunosuchus” shartegensis and Kansajsuchus are relatively derived goniopholidids, and part of a pan-east-Laurasian radiation of goniopholidids from which the European goniopholidids subsequently radiated. No characters can be used to distinguish “Sunosuchus” shartegensis from “S.” thailandicus; the two species are therefore synonymized. Turanosuchus aralensis is here considered a nomen dubium. Cladistic analysis suggests that Sunosuchus is polyphyletic, indicating a higher degree of diversification than was previously thought, but also pointing to the need for further systematic revision.

The aim of this paper is the study of porous Si prepared by preferential anodic dissolution in concentrated HF acid solutions. Porous silicon layers exhibited extremely efficient luminescence in the 700-900 nm range at room temperature. Basic characteristics of this luminescence strongly suggest the intrinsic origin of the process, directly related to quantum confinement. The additional transmission-electron-microscopy and electron-diffraction studies - were performed to support hypothesis that luminescence originates from silicon nanostructures.

Opis:
A multiferroic tunnel junction (MFTJ) is a promising device for future memory systems with discrete and different logic states which are controlled by a combination of electric and magnetic fields. The goal of ongoing research is to present ferroelectric and ferromagnetic properties, especially at room temperature (RT), represented as high values of tunnel electroresistance (TER) and tunnel magnetoresistance (TMR). A key aspect is the appropriate preparation of a sample allowing epitaxial growth. The thin layers were prepared by pulsed laser deposition on atomically smooth monocrystalline SrTiO₃ (STO) substrates. The ferromagnetic metal layers La_{0.67}Sr_{0.33}MnO₃ (LSMO) are separated by a layer of a ferroelectric insulator - BaTiO₃ (BTO). The same structure of LSMO, BTO and STO (perovskite) and a similar lattice constant make it possible to obtain high-quality heterostructures. Magnetic measurements confirm differences in the magnetic coercivity of the top and bottom LSMO layer, which allows to obtain their parallel and antiparallel magnetization orientation. A modification of the interfaces of BTO by thin MgO layer enables an increase in the value of the TER effect.

Opis:
Polarization-resolved photoluminescence from two-dimensional GaAs/GaAlAs heterostructures doped with acceptors was studied in high magnetic fields. Measurements were carried out in low temperatures up to 2 K and magnetic field up to 21 T. Experiments performed in the Faraday configuration enabled to resolve hole states with different spin orientation. We observed a nonlinear behavior of valence-band g factor in strong magnetic fields. To explain obtained results, a detailed theoretical calculation was carried out based on the Luttinger model for valence-band states. We examined the spin splitting of hole levels under the influence of both external magnetic field and built-in electric field existing in doped heterostructures. Changes of hole g factor with the width of the structure and the density of two-dimensional carriers are discussed.
