On the Problem of Shale Gas Mining in Ukraine

New sources of power resources are one of the most important and central tasks for the human. In these latter days all energy-dependent countries develop alternative technologies to produce renewable fuel: nuclear power, wind power, solar power, innovative approaches on the basis of genetically modified organisms etc

Reflection of electrons from a domain wall in magnetic nanojunctions

Electronic transport through thin and laterally constrained domain walls in ferromagnetic nanojunctions is analyzed theoretically. The description is formulated in the basis of scattering states. The resistance of the domain wall is calculated in the regime of strong electron reflection from the wall. It is shown that the corresponding magnetoresistance can be large, which is in a qualitative agreement with recent experimental observations. We also calculate the spin current flowing through the wall and the spin polarization of electron gas due to reflections from the domain wall.Comment: 7 pages, 4 figure

Международные непатентованные наименования биологических и биотехнологических лекарственных средств

The article presents generalized information about the program of the World Health Organization (WHO) related to International Nonproprietary Names (INN) of biological and biotechnological drugs. It reflects general principles for selecting INN for biological and biotechnological preparations, immunoglobulins (sera), preparations for gene therapy, glycosylated proteins and peptides, non-glycosylated proteins peptides and proteins, hybrid proteins, blood preparations, monoclonal antibodies, skin substitutes, transgenic products, vaccines, biosimilars. The conclusion was made about the need for an early solution to the global problem of assigning INN to biological and biotechnological drugs, while the number of authorized products remains relatively small.Представлена обобщенная информация о программе Всемирной организации здравоохранения (ВОЗ) по международным непатентованным наименованиям (МНН) биологических и биотехнологических лекарственных средств. Отражены общие принципы выбора МНН для биологических и биотехнологических препаратов, иммуноглобулинов (сывороток), препаратов генной терапии, гликозилированных белков и пептидов, негликозилированных белков и пептидов, гибридных белков, препаратов крови, моноклональных антител, заменителей кожи, трансгенных продуктов, вакцин, биоаналоговых лекарственных препаратов. Сделан вывод о необходимости скорейшего решения глобальной проблемы присвоения МНН биологическим и биотехнологическим препаратам, пока число зарегистрированных препаратов является относительно небольшим

The Tri-Party Repo Market before the 2010 Reforms

This paper provides a descriptive and quantitative account of the tri-party repo market before the reforms proposed in 2010 by the Task Force on Tri-Party Repo Infrastructure (Task Force 2010). We provide an extensive description of the mechanics of this market. We also use data from July 2008 to early 2010 to document quantitative features of he market. We find that both the level of haircuts and the amount of funding were surprisingly stable in this market. The stability of the margins is in contrast to evidence from other repo markets. Perhaps surprisingly, the data reveal relatively few signs of stress in the market for dealers other than Lehman Brothers, on which we provide some evidence. This suggests that runs in the tri-party repo market may occur precipitously, like traditional bank runs, rather than manifest themselves as large increases in margins

Формирование хранилища и анализ больших данных передвижений в городе

В статье рассмотрена концепция построения хранилища данных путей передвижения для интеллектуальной транспортной системы города. Приведен математический аппарат формализованного описания транспортной системы на основе гиперсети, дуги которой являются путями передвижения. Рассмотрен рекурсивный алгоритм получения данных о путях передвижения, а также механизм использования матриц смежности по маршрутным связям. Исследования проводятся в рамках проекта АР05133699 «Исследование и разработка инновационно-телекоммуникационных технологий с использованием современных кибертехнических средств для интеллектуальной транспортной системы города». The article discusses the concept of constructing a repository of data on travel routes for the intellectual transport system of the city. The mathematical apparatus of a formalized description of a transport system based on a hypernet, whose arcs are paths of movement, is given. A recursive algorithm for obtaining data on paths of movement, as well as a mechanism for using adjacency matrices for route connections, is considered. Research is carried out as part of the project AR05133699 “Research and development of innovative telecommunication technologies using modern cyber-technical means for the intellectual transport system of the city”
