Opis:
The internal differentiation of Slavic studies (history, linguistics, literary criticism, cultural studies) loses the perspective of system integrity. The development of the humanities led to the emergence of trends aimed at a complex comprehension of Slavdom in the light of the general patterns of European civilization and the characteristics of their local refraction. In the development of such a set of problems, thinking in the categories of holism, methods of interdisciplinarity and comparative studies are especially promising.
Внутренняя дифференциация славистики (история, языкознание, литературоведение, культурология) утрачивает перспективу системной целостности. Развитие гуманитарных наук обусловило появление направлений, нацеленных на комплексное постижение славянства в свете общих закономерностей европейской цивилизации и особенностей их локального преломления. В разработке такого комплекса проблем особенно перспективным представляется мышление в категориях холизма, методы интердисциплинарности и компаративистики.

Opis:
The aim of studies was the recognition of the contemporary denudation considering tillage translocation and water soil erosion. This study was performed in the typical last glacial relief. The Cs-137 inventory was analysed along two hillslope profiles and at their footslopes. The value of soil erosion and sedimentation was calculated using the proportional model and the simplified mass balance model. Studies showed that eroded soil from upper and middle segments of the slopes was re-deposited on concave segments of the slopes. The erosion rate was 0.5-1.6 mm on the top of hills and 0.8-3.2 mm on their slopes. The deposition occurs on the concave slope at rate of 3.8-6.6 mm per year on average. Erosion-deposition balance indicate that the small part of eroded soil was exported to the valley bottom and bottom of depression. The share of the water rill and interrill erosion in the total of topsoil erosion is range from 1 to 10% depending on used model. Tillage translocation is the main process shaped a small hills in the last glacial ares.

Opis:
This work presents a use of the ¹³⁷Cs method in the reseach of soil erosion and sedimentation on the agricultural loessial land. There is an urgent need to obtain reliable quantitative data of the soil translocation in agricultural areas and to choose an effective method of soil conservation. After deposition on the land surface, ¹³⁷Cs is rapidly and strongly adsorbed by soil particles. The isotope has been present in the environment since the beginning of nuclear weapon testing and nowadays it is a part of many ecosystems. ¹³⁷Cs is therefore a valuable tracer to study soil erosion and sedimentation rate. Advantages and limitations of the method are discussed in this articles. The activity of the ¹³⁷Cs in soil samples from 4 slopes was measured by means of high-resolution gamma spectrometry and then the ¹³⁷Cs inventories for sampling points were calculated. The ¹³⁷Cs inventories relate to the erosion and deposition rates. The value of soil erosion was calculated by using the proportional model as well as the three mass balance models. The ¹³⁷Cs inventory for studied cultivated field ranges from less than 1.0 up to more than 10.0 kBq m⁻². Differences in ¹³⁷Cs inventory distribution on the terraced and unterraced slopes are clear. The results show that agricultural terraces in the study area were created alter the main period of cesium fallout and that the intensity of soil erosion in the study area appear to be significant.

The author presents the results of the engineering-geological research carried out along of the Potulicka St. and Bohaterów Warszawy Ave. in Szczecin. The analysis relates to geological drillings and made soundings carried out using an SL and ZW. Additionally, author presents use of high resolution seismic research as example to recognize the influence of the present-day vertical movements the ground surface, which have a significant effect on the instability of many parts of the existing technical infrastructure. Seismic high-resolution research carried out by the aid of apparatus CS-5G-1, where the reflection method was used. In the field research, used range Z = 50 ms, allowing the penetration of seismic waves in the Quaternary deposits to a depth of 40 m below terraine level. Author presents example of seismic research in the area of flood embankments of the Chemical Plants in Police (Western Pomerania), which show the existence of present-day vertical movements of the ground surface and which of similar size and in the same way can have a real impact in many areas on the instability of the existing civil engineering infrastructure, and can contribute to serious accidents or even disasters. As shown of the engineering-geological research in the area of Potulicka Street and Bohaterów Warszawy Avenue in Szczecin and seismic investigations, contemporary vertical movements in the Western Pomerania have different average rate of displacement of geological layers from 5–10 mm / year.

This paper presents a novel method to obtain optimum design for a worm gear drive used in sugar industries taking into account certain constraints of industrial relevance. The objective of this research is to minimize volume of worm gear drive. Gear ratio, face width and pitch circle diameters of worm and worm wheel are considered as design variables. Industry relevant constraints viz. gear strength capacity, wear capacity, thermal capacity, dynamic load, self locking, and face width are considered. Besides this other constraints such as maximum power transmission capacity, centre distances, deflection of worm and beam strength of worm are also considered. Nature inspired optimization algorithms, namely, Simulated Annealing (SA), Firefly (FA), Cuckoo Search (CS) and MATLAB solvers fmincon and GA are used for solving this problem in MATLAB environment. Results of simulation are analysed and presented.

Opis:
Children’s contemporary literature often presents an ambiguous and even immoral world of values, not to speak of Christian virtues, which are neither emphatically mentioned nor even faintly evoked. Theological virtues enhance human capacities and elevate every person to their highest being, to the supernatural order they are created for. Directly related to the Scriptures, for they are revealed, the theological virtues suggest an unavoidable and clear connection to God. In C.S. Lewis’ Chronicles of Narnia we find a useful counterexample to teaching morals through literature: these seven fantasy novels provide multiple examples of how to be faithful, hopeful and even how to practice the virtue of charity. Considering that through a fictional evocation of certain concepts these might be apprehended more significantly, in this paper we aim to explore new readings of the saga that go beyond a general approach in order to transcend its allegorical mechanisms and respond to criteria such as the virtue of charity and its two main features: vicariousness and forgiveness.
Współczesna literatura dziecięca często przedstawia niejednoznaczny, a nawet niemoralny świat wartości, nie mówiąc już o cnotach chrześcijańskich, na które nie tylko nie kładzie ona nacisku, ale o których nie wspomina nawet mimochodem. Cnoty teologiczne doskonalą ludzkie sprawności i podnoszą człowieka do najwyższego poziomu jego bytu, do porządku nadprzyrodzonego, dla którego został stworzony. Cnoty teologiczne, bezpośrednio zakorzenione w Piśmie Świętym i należące do materii Objawienia, w nieunikniony sposób wyraźnie odsyłają do Boga. Wbrew rozpowszechnionemu trendowi, Opowieści z Narnii C.S. Lewisa stanowią użyteczny przykład nauczania moralności poprzez literaturę: te siedem powieści fantasy daje wiele przykładów, jak być wiernym, pełnym nadziei, a nawet jak praktykować cnotę miłości. Biorąc pod uwagę fakt, że pewne pojęcia można uchwycić znacznie lepiej poprzez ich fikcyjną ewokację, w niniejszym artykule zamierzamy dokonać nowego odczytania sagi, odbiegającego od jej standardowego ujęcia, aby wyjść poza jej alegoryczne mechanizmy i rozpoznać cnotę miłości oraz jej dwojaki charakter: zastępczy i przebaczający.

Opis:
Events and transients are becoming more and more crucial in modern astronomy such as supernovae, gamma-ray bursts and so on. VOEvent messages have all information to make the follow-up observations for transients and events which forces the scientists to make robotic observations. Robotic autonomous telescopes usually run under the control of a scheduler, which provides high-level control by selecting astronomical targets for observation. TUY 40 is a new robotic autonomous telescope control system designed by TÜBİTAK National Observatory (TUG). TUY 40 is based on 16 inch Meade LX-200 telescope mount and optical tube without any Meade electronic components and drive motors. The telescope control software developed on open-source Talon software and LabVIEW is presented. The algorithm for telescope control (slewing, tracking, homing etc.) was implemented in National Instruments PXI chassis written in LabVIEW real-time software from scratch. Talon is open-source software based on the GNU/C UNIX platform. A new TCP/IP library was implemented within Talon software to communicate with hard real-time telescope control software in LabVIEW PXI chassis. Initial setup without any permanent pier and polar alignment showed that the pointing error of the telescope has been obtained as 2.22 arcmin (132 arcsec) in RA axis (horizontal axis of the image) and 25 arcsec in Dec axis (vertical axis of the image), and tracking error has been observed as ≈ 4.8 arcsec per second.

Opis:
In this article two Church Slavonic old prints: the Ostrog Bible (1581) and the Jabłeczna Gospel Book (1771) – were subjected to collation with the lexis of the Ostromir Gospel Book. All the texts are the part of the Ruthenian recension. The purpose of the comparison was to show and explain the observed differences at the lexical level. The confrontation allowed to differentiate between the language layers comprising the texts: the Greek, Moravian, West-Bulgarian, East-Bulgarian and Ruthenian ones. What is more, both old prints are identical (with the exception of three lexemes). Taking into consideration the few discrepancies, it can definitely be said that the Evangeliary of 1771 retained the pre-Niconian lexis virtually intact. Furthermore, juxtaposing proved that the Gospel aprakos differs from the Evangeliary and from the complete edition of the Bible not only in the organization of the content but also in the lexical and word formation means.

Opis:
The cost-effectiveness of resistive plate chamber detectors and their very good timing characteristics, open the possibility to build affordable time-of-flight positron emission tomography systems with a large axial field-of-view. Simulations suggest that, under reasonable assumptions, the absolute 3D true sensitivity, spatial resolution, and noise equivalent count rate of such systems for human whole-body screening, may exceed that of present crystal-based PET technology. However, due to the lack of energy resolution, although having energy sensitivity, the scatter fraction is expected to be considerably higher than that presented by crystal-based PET scanners. In the present paper, the simulation work done so far to access the expected performance of a resistive plate chamber time-of-flight-PET system with 2400 mm length axial field-of-view, a time resolution of 300 ps full width at half maximum for photons pairs, and depth-of-interaction information, will be revised.

Opis:
Calf diarrhea continues to be the major problem of calves in the neonatal period. The effect of zeolites has been increasingly studied in ruminant health in recent years. In the present study, the efficacy of cristobalite, a zeolite, in neonatal calf diarrhea was studied first time. For this purpose, twenty-five neonatal calves with diarrheas were divided into two groups, and Group 1 (n=12) received conventional treatment and Group 2 (n=13) received cristobalite (Zoosorb 10 mg/kg) orally 3 times a day in addition to conventional treatment. Escherichia coli k99 and CS31a, bovine rotavirus and bovine coronavirus were isolated from fecal samples at the beginning of the treatment, on the third day and before discharge. It was determined that the recovery period in Group 2 was 0.95 (20.6%) days shorter than in Group 1 (p<0.05) while no viral agents were found on the fifth day in Group 2, viral shedding continued in 4 of 5 calves in Group 1. In conclusion, the study revealed that cristobalite speeds the recovery time and possibly decreases viral shedding in neonatal calf diarrhea, demonstrating a remarkable efficiency in the treatment.

Opis:
On the basis of the data reported by Flint and Paulusz, we have undertaken a theoretical investigation of the intensity mechanism for the various emissions:Γ$\text{}_{8}$($\text{}^{2}$T$\text{}_{2g}$ ) → Γ$\text{}_{8}$($\text{}^{4}$A$\text{}_{2g}$), Γ$\text{}_{8}$($\text{}^{2}$E$\text{}_{g}$), Γ_8($\text{}^{2}$T$\text{}_{1g}$), Γ$\text{}_{6}$($\text{}^{2}$T$\text{}_{1g}$) for the Cs$\text{}_{2}$NaScCl$\text{}_{6}$:MoCl$\text{}_{6}^{3-}$ system in the Fm3m-space group. The experimental data available refer to the visible and near infrared luminescence spectra of MoCl$\text{}_{6}^{3-}$ complex ion in different hosts, such as Cs$\text{}_{2}$NaMCl$\text{}_{6}$ (M = Sc, Y, In), measured between 15,000 cm$\text{}^{-1}$ and 3,000 cm$\text{}^{-1}$ at liquid helium temperatures. At least, five luminescence transitions have been identified and assigned and each of them show extensive vibronic structure. A careful analysis of this experimental data shows that for the various observed electronic transitions, the vibrational frequencies change only slightly, and therefore there is no indication that the system undergoes both a significant and relevant Jahn-Teller distortion (along an active coordinate). There is however clear evidence that for the chloro-elpasolites, there is a strong resonance interaction between ν$\text{}_{3}$(τ$\text{}_{1u}$ : stretching) of the MoX$\text{}_{6}^{3-}$, complex ion and that of the host when M = In, Y. Thus for M = Sc, the slighter higher host ν$\text{}_{3}$, wave number is likely to minimize the effect of this coupling. This evidence will allow us for the Cs$\text{}_{2}$NaScCl$\text{}_{6}$:MoCl$\text{}_{6}^{3-}$ system to neglect, in the first-order approximation, the coupling among the internal and the external vibrations and to proceed using a both a molecular and the independent system models.
