TL Ages of Loesses from the Last Two Glacials in Se Poland Loesses cover a large area in SE Poland so their exploration is an important part of the palaeogeographical studies on Pleistocene. The research involves stratigraphic problems. At present, luminescence dating provides the greatest number of chronostratigraphic data concerning loesses. In this work we report TL ages of loesses from the last two glacial cycles in SE Poland, obtained in the TL Laboratory of the Department of Physical Geography and Palaeogeography, Maria Curie-Skłodowska University in Lublin after 1993. Samples for TL dating were collected in 11 loess profiles (2-9 samples in each site) in order to obtain additional information for stratigraphic interpretations deduced from paleopedological, lithological, structural, and other data. Basing on the comparison of 54 TL ages, we can determine age intervals, in which the dating results of similar values assemble, and then get general information about the periods of intensified Aeolian accumulation related to defined stratigraphic units. The TL ages of all samples were obtained using the total-bleach method (TB) for the determination of the equivalent dose.

The aim. Determination of the need to raise awareness of the population about multivitamins and the criteria for their rational choice. Materials and research methods. To achieve the goal of the study, it was necessary to develop a questionnaire for visitors to pharmacies and carry out an anonymous survey of them. All adult visitors of the pharmacy were attracted to the survey. The developed questionnaire consisted of 3 parts and contained 32 questions processed in the course of our own research. Research results. Among the pharmacy visitors we surveyed, the majority were between the ages of 35–55, approximately equally divided were men and women who mainly lived in the Kiev region (87 %), were not students and did not have educational levels of bachelor or master, and had no relation in health care education. Summarizing the information obtained in the course of processing questionnaires with the answers of visitors to pharmacies, it can be noted that in the surveyed group of respondents there is a certain interest and indifference to the discussed aspects, but quite often there is a lack of knowledge in this regard. Conclusions. In the course of analyzing the results of the questionnaire survey, the level of awareness of the population regarding general information about the pharmacology of multivitamin drugs and the criteria for their correct choice was determined. From the data obtained, it can be concluded that on many issues the respondents showed an insufficient level of knowledge, which justifies the need for additional information about multivitamins, and indicates that better it should be done with participation of a specialist with a pharmaceutical education or physician. Mostly the population lacks knowledge on the issues listed in the second part of the questionnaire, namely, on general information about the biological and pharmacological properties of vitamins. It was found that the information obtained from the Internet or other media, including advertising, has a significant impact on the awareness and decision of the respondents

Introduction In electron microscopic investigations of crystalline specimens the direct observation of the electron diffraction pattern gives additional information about the specimen. The quality of this information depends on the quality of the crystals or the crystal area contributing to the diffraction pattern. By selected area diffraction in a conventional electron microscope, specimen areas as small as 1 µ in diameter can be investigated. It is well known that crystal areas of that size which must be thin enough (in the order of 1000 Å) for electron microscopic investigations are normally somewhat distorted by bending, or they are not homogeneous. Furthermore, the crystal surface is not well defined over such a large area. These are facts which cause reduction of information in the diffraction pattern. The intensity of a diffraction spot, for example, depends on the crystal thickness. If the thickness is not uniform over the investigated area, one observes an averaged intensity, so that the intensity distribution in the diffraction pattern cannot be used for an analysis unless additional information is available.

Abstract A basic set of experiments for the determination of mechanical properties of sands is described. This includes the determination of basic physical and mechanical properties, as conventionally applied in soil mechanics, as well as some additional experiments, which provide further information on mechanical properties of granular soils. These additional experiments allow for determination of steady state and instability lines, stress-strain relations for isotropic loading and pure shearing, and simple cyclic shearing tests. Unconventional oedometric experiments are also presented. Necessary laboratory equipment is described, which includes a triaxial apparatus equipped with local strain gauges, an oedometer capable of measuring lateral stresses and a simple cyclic shearing apparatus. The above experiments provide additional information on soil’s properties, which is useful in studying the following phenomena: pre-failure deformations of sand including cyclic loading compaction, pore-pressure generation and liquefaction, both static and caused by cyclic loadings, the effect of sand initial anisotropy and various instabilities. An important feature of the experiments described is that they make it possible to determine the initial state of sand, defined as either contractive or dilative. Experimental results for the “Gdynia” model sand are shown.

Abstract The identification of the right order of the equation in applied fractional modeling plays an important role. In this paper we consider an inverse problem for determining the order of time fractional derivative in a subdiffusion equation with an arbitrary second order elliptic differential operator. We prove that the additional information about the solution at a fixed time instant at a monitoring location, as “the observation data”, identifies uniquely the order of the fractional derivative.

The purpose of this paper was to model, with the help of neutrosophic fuzzy numbers, the optimal financial asset portfolios, offering additional information to those investing in the capital market. The optimal neutrosophic portfolios are those categories of portfolios consisting of two or more financial assets, modeled using neutrosophic triangular numbers, that allow for the determination of financial performance indicators, respectively the neutrosophic average, the neutrosophic risk, for each financial asset, and the neutrosophic covariance as well as the determination of the portfolio return, respectively of the portfolio risk. There are two essential conditions established by rational investors on the capital market to obtain an optimal financial assets portfolio, respectively by fixing the financial return at the estimated level as well as minimizing the risk of the financial assets neutrosophic portfolio. These conditions allowed us to compute the financial assets’ share in the total value of the neutrosophic portfolios, for which the financial return reaches the level set by investors and the financial risk has the minimum value. In financial terms, the financial assets’ share answers the legitimate question of rational investors in the capital market regarding the amount of money they must invest in compliance with the optimal conditions regarding the neutrosophic return and risk.

AbstractThe sample preparation procedures which enable us to observe large areas over a few tens of microns in one-dimension of semiconducting heteroepitaxial materials are described. The main principle involves the careful grinding and polishing of samples. In these procedures, another side thinning of the specimen after finishing initial side polishing is carried out using a sample platform by hand throughout all of the following steps. It is shown that for some typical examples of heteroepitaxial films general information concerning the film growth modes and structures, as well as the defect morphologies and natures introduced during growth can be effectively obtained by using the present technique.

AbstractIn this study, we present results of luminescence dating using CW-OSL, LM-OSL and TL on heated quartz from the archaeological and historical site in Karakorum – the ancient capital of Mongolia, to test their convergence with the age control in the form of the Karakorum inscription 1346. The TL spectra conducted on quartz from red and grey coloured bricks appeared to be characteristic of the technological origin. Quartz TL from red bricks showed a UV emission band at ~360 nm and a strong fast OSL component dominated signal. In contrast, blue emission detected in the TL spectra of grey coloured bricks, resulting possibly in the medium component dominated OSL signal. Finally, OSL and TL results gave dates from 1180±70 AD to 1360±70 consistent with the expected ages.

This study aims to analyze the role of job satisfaction in mediating the relationship between emotional intelligence and intellectual intelligence on the performance of the high school teachers. This study uses a research design with an associative quantitative approach. Data was collected through documentation and online questionnaires. This study used a sample of 39 respondents with the determination of the sample size using the saturated sample formula. Partial least square is applied to examine the relationship between teacher performance, job satisfaction, emotional intelligence and intellectual intelligence. The results of this study indicate that of the seven hypotheses developed there are two accepted hypotheses, that is, for the effect of emotional intelligence on job satisfaction, it is obtained that the results of a significant effect and the influence of spiritual intelligence on teacher performance are also obtained significant results. Meanwhile, the other 5 hypotheses developed were not significant. Through the findings of this study, it is hoped that it can provide additional information for various parties, especially the school, to pay attention to the factors that affect teacher performance and job satisfaction, so that teachers gain comfort and confidence to continue to improve their performance in implementing learning in schools.

Key approaches to clarify the notion of the national and cultural component were explored in application to the task of teaching lexical means of communication to Russian speaking students. The authors highlight its significant features that are important in terms of the teaching methods. A number of conclusions, which are significant for this task, were made based on the results of analyzing Korean sememes. The meanings, which are correlated with the national-cultural information conveying ethnocultural realities of the native speakers of the studied language, were determined. Groups of actual issues related to the determination of the scope of national-cultural information to be mastered by the students, mechanisms of its transmission in teaching and methods for the formation of relevant associations and images were highlighted. It is shown that the scope of accumulation of national-cultural information can vary at a certain level of education, therefore, it seems reasonable to talk about the list of associations as additional information to a certain lexical meaning, which has yet to become knowledge and be subsequently used at the stages of training and application of forming the lexical skills. It is stated that in respect of the linguo-didactic aspect it seems more rational to talk about a certain number of associations necessary for complete disclosure of the lexical meaning of the words, since neither translation nor non-translation methods of semantization by themselves allow students to differentiate the corresponding concepts without additional national-cultural information. Thus, methods of the most effective delivery of such information are to be specified for better results of teaching lexical means of communication to students.
