Полимерные микросферы в качестве антистатических компонентов защитного слоя светочувствительных материалов

Polymeric micro spheres with different structure of surface, narrow distribution of particles dimensions, having «nucleus-envelope» structure were synthesized. The polymeric micro spheres were applied into protection layers of emulsion photographic materials. The influence of polymeric micro spheres to sensitometric characteristics of light-sensitive photographic materials was studied. The possibility of using them as antistatic components was shown.Синтезированы полимерные микросферы с различным строением поверхности, с узким распределением частиц по размерам, имеющие структуру «ядро-оболочка». Полимерные микросферы введены в защитные слои эмульсионных фотографических материалов. Изучено влияние полимерных микросфер на сенситометрические характеристики светочувствительных материалов и показана возможность использования их в качестве антистатических компонентов

Public political narratives: developing a neglected source through the exploratory case of Russia in the Putin-Medvedev era

The place of narrative in political science is an issue that resurfaces with regularity, usually focusing on the questions of generalisability, evidence and causality which lie at the heart of the discipline. Most such debate concerns the use of narrative by political scientists. Far less attention has been devoted to the use of narrative by political actors, despite its relative ubiquity. Even where such attention has been given, it concentrates less on the narrative per se, and more on its performance and impact. However, the nature of public political narratives means that analysis of them facilitates a holistic understanding of their narrators' politics. A public political narrative consists of a sequential account given by political actors connecting selected, specific developments so as to impose a desired order on them. Taking contemporary Russia as an exploratory case, narrative analysis draws out the motivations, world view and inconsistencies within the Putin-Medvedev regime. Recurring motifs and symbols identify the regime's political priorities, explaining policy choices and revealing future concerns. Narrative has a predictive aspect, identifying likely policy responses to unexpected events. Narratives capture time, and shifts in their temporalities indicate changes in self-conceptualisation and political priorities. Temporal appropriations include or exclude particular agential and causal explanations. The relationship between their plots and subplots represents a political signalling process. Public political narratives provide temporally and spatially specific exceptionalist accounts, but their combinatory quality also facilitates comparative analysis. The approach essayed here provides methodological generalisability, arguing that the neglect of public political narratives merits correcting

Methods of determination of electrophysical parameters of materials

The aim of this work is the study of methods of determination of electrophysical parameters of materials non-resonant and resonant methods. In the course of the work performed were considered the existing methods of determination of electrophysical parameters of materials in the field of high, ultra high and extremely high frequencies offered by the leading manufacturers on the market of measuring equipment. As a result of this work, we analyzed the methods for finding the values of electrical parameters of investigated materials for different frequency ranges. The results of the work were carried out practical measurements and conclusions about the applicability of the considered methods.Целью данной работы является исследование методов определения электрофизических параметров материалов нерезонансными и резонансными методами. В ходе выполненной работы были рассмотрены существующие методы определения электрофизических параметров материалов в области высоких, сверхвысоких и крайне высоких частот, которые предлагаются ведущими производителями на рынке измерительного оборудования. В результате выполненной работы были проанализированы методы нахождения значений электрофизических параметров исследуемых материалов для различных диапазонов частот. По результатам работы были проведены практические измерения и сделаны выводы о применимости рассматриваемых методов

Transplantation of unconserved autologous and cryoconserved allogenic vein with a valve

Morphofunctional properties of autologous unconserved and allogenic conserved vein implants were compared in dogs. After 14 months, 69.2% of autologous grafts and only 20% of conserved allografts remained functional. Histological examination revealed damage to all layers of the venous wall, although endothelial desquamation is the major-function. of graft thrombosis. Histological manifestations of damage to allografts were more pronounced. which corresponds to the level of thrombosis. However, these changes are reversible, and if the passability of the graft is preserved during the early period after surgery, they have no effect on the graft in a remote period

Efficiency of vagus nerve stimulation in epilepsy (literature review and case report)

Despite significant advances in epileptology, approximately one-third of patients suffer from drug-resistant epilepsy. Numerous approaches are currently available to treat epilepsy; however, there are still many patients with treatment-resistant epilepsy, in whom antiepileptic drugs are ineffective and surgical treatment is impossible. Thus, searching for new effective antiepileptic drugs and alternative treatments (such as vagus nerve stimulation) for these patients remains highly relevant. This literature review covers the indications for and the efficacy and tolerability of vagus nerve stimulation in patients with epilepsy. We also report a case of successful treatment of a patient with drug-resistant epilepsy using this method

Polymeric microspheres as antistatic components of protection layer for light-sensitive materials

Polymeric micro spheres with different structure of surface, narrow distribution of particles dimensions, having «nucleus-envelope» structure were synthesized.

CLINICAL LATERALIZING SIGNS IN SYMPTOMATIC TEMPORAL LOBE EPILEPSY

Abstract: the article presents a review of world literature on significance of various clinical lateralizing signs in temporal lobe epilepsy, such as dystonic posturing, limb automatisms, ictal and postictal aphasia, ictal nystagmus, head turning, periiktal headache, etc. The results of current research are compared with previously published reports. The ictal dystonic unilateral limb posturing (possibly isolated in a hand, foot, predominantly in distal parts of limbs) is still one of the most informative lateralizing signs and it is lateralized in contralateral hemisphere in 100% of cases. It is shown that the “early” and “late” head turning, and unilateral limb automatisms are the most important and convincing lateralizing signs, which must be considered in connection with the EEG data to determine the epileptogenic focus in patients with temporal lobe epilepsy
