Neuropsychological Study of Resilience of School Graduates of the Region of Ecological Trouble
The article presents the data of neuropsychological research in the framework of a comprehensive study of the resilience of the youth population (secondary school graduates) of the region of ecological trouble – Zabajkal‘skij kraj. The authors consider resilience as a systemic characteristic of the system ‘man–life environment’. The model of resilience including psychophysiological, psychological and personal levels is offered. Standardized psychometric and neuropsychological methods are used to evaluate level’s indicators. School graduates residing in ecologically unfavorable territories identified drift of psychophysiological level in the direction of lower standards and regulatory intensity indicators of psychological and personal levels ofresilience. Using a neuropsychological approach with the aim of finding mechanisms to a reduction of the indicators of the psycho-physiological level of resilience allowed us to determine the presence of signs of deficiency of certain brain areas (posterior frontal and parietal). It was established that with the increase of degree of the ecology trouble territories of research, there is a reliable increase of mistakes ofaccomplishment by test subjects who live on them, the neuropsychological tests investigating visually spatial functions, and also functions of the serial organization of mental activity. Though there is the presence of correlations between indicators of different levels of resilience, but the rating and the explanation by virtue of their disparate data is difficult. The search for correlates, in this case, can be more aimed at proving the possibility of the existence of the proposed model of resilience, its consistency and productivity of the instruments that are used for its study.

THE INFLUENCE OF CARBON NANOTUBES ON MORPHOLOGICAL AND ANALYTICAL CHARACTERISTICS OF CARBON SCREEN-PRINTED ELECTRODES
Multi-walled carbon nanotubes (CNT) are used as a modifier of carbon containing thick film electrodes for adsorptive stripping voltammetry. Morphological and analytical characteristics of electrodes with and without CNT were compared. It was found that the addition o f CNT increases the effective surface of the electrode and to facilitate the reduction of calomel. Electrodes with CNT have a twice higher sensitivity and 3 - 5 times ower limit of detection were shown
Global fine-resolution data on springtail abundance and community structure
Springtails (Collembola) inhabit soils from the Arctic to the Antarctic and comprise an estimated ~32% of all terrestrial arthropods on Earth. Here, we present a global, spatially-explicit database on springtail communities that includes 249,912 occurrences from 44,999 samples and 2,990 sites. These data are mainly raw sample-level records at the species level collected predominantly from private archives of the authors that were quality-controlled and taxonomically-standardised. Despite covering all continents, most of the sample-level data come from the European continent (82.5% of all samples) and represent four habitats: woodlands (57.4%), grasslands (14.0%), agrosystems (13.7%) and scrublands (9.0%). We included sampling by soil layers, and across seasons and years, representing temporal and spatial within-site variation in springtail communities. We also provided data use and sharing guidelines and R code to facilitate the use of the database by other researchers. This data paper describes a static version of the database at the publication date, but the database will be further expanded to include underrepresented regions and linked with trait data.</p

Corporate reputation past and future: a review and integration of existing literature and a framework for future research
The concept of corporate reputation is steadily growing in interest among management researchers and practitioners. In this article, we trace key milestones in the development of reputation literature over the past six decades to suggest important research gaps as well as to provide contextual background for a subsequent integration of approaches and future outlook. In particular we explore the need for better categorised outcomes; a wider range of causes; and a deeper understanding of contingencies and moderators to advance the field beyond its current state while also taking account of developments in the macro business environment. The article concludes by presenting a novel reputation framework that integrates insights from reputation theory and studies, outlines gaps in knowledge and offers directions for future research
Initial renal function and type of chemotherapy: impact on treatment efficacy in patients with chronic lymphocytic leukemia
The paper presents an assessment of treatment efficacy in chronic lymphocytic leukemia CLL patients according to chemotherapy type and initial renal function. The high efficacy of chemotherapy with fludarabine in CLL patients with or without renal failure at diagnosis was revealed. However, regardless of chemotherapy type initial treatment response was worse in patients with renal failure.</p

DEVELOPMENT AND VALIDATION OF METHOD FOR POTENTIOMETRIC DETERMINATION OF SILVER IN PHARMACEUTICAL SUBSTANCE «ARGAMID»
The article presents data on the development of an assay method of silver in pharmaceutical substance «Argamid» based on silver salt sulfadimidine. The method is based on the rhodanometric titration with potentiometric indication of the final point. The results of the validation assessment of the method are shown
Optimization of a single-embryo transfer by using time-lapse microscopy in IVF and ICSI programs
Introduction. Due to refinements of assisted reproductive technology, the number of multiple pregnancies has increased substantially. Therefore, transfer of a single embryo, as opposed to multiple embryos, is a top-priority task in ART-based infertility treatment. Time-lapse microscopy (TLM) is a tool for selecting quality embryos for transfer.The aim of the study was to assess the outcomes of single-embryo transfer following embryo incubation in a TLM-equipped incubator in patients undergoing IVF and ICSI.Methods. The study was carried out in 743 infertile women. Single-embryo transfer following incubation in a TLM-equipped incubator was performed in 282 patients, who formed the main group; the control group consisted of 461 patients undergoing singleembryo transfer following a traditional culture and embryo selection procedure. We assessed the quality of transferred embryos, the rates of clinical pregnancy and live birth rates.Results. The groups did not differ in the proportion of IVF and ICSI cycles, terms of age and infertility factors. In the study group, there was a higher proportion of excellent quality embryos for transfer (p = 0.001), a higher proportion of cycles with elective embryo transfer (p = 0.001) and a higher proportion of cycles with cryopreservation of embryos (p <0.001). In the subgroup of non-elective embryo transfer with using of TLM, the clinical pregnancy rate was 10% higher than in the control group (p = 0.03). The live birth rates did not differ between the TLM group and the conventional culture group depending on the type of embryo transfer.Conclusion. Our studies show that the use of time-lapse microscopy can increase the effectiveness of IVF and ICSI programs. Continuous monitoring with short intervals provides more information about the development of embryos than the standard daily assessment
