Youth policy as a tool for integration
Статья посвящена вопросам молодежного сотрудничества Польши и России в условиях мировой нестабильности глобализационных процессов. Отмечается необходимость политической консолидации стран с целью преодоления многочисленных угроз современной эпохи. В статье выделяются проблемы между Польшей и Россией, обосновывается возможность сближения двух стран, несмотря на неоднозначность их культурных и исторических взаимодействий. Обозначаются механизмы оптимального молодежного сотрудничества.The article is devoted to questions of youth cooperation between Poland and Russia in the conditions of global instability globalization processes. The necessity of political consolidation of countries to overcome the multiple threats of the modern age. In article highlighted the problems between Poland and Russia, and proves the possibility of rapprochement between the two countries, despite the ambiguity of their cultural and historical interactions. Represented optimal mechanisms of youth cooperation
Surgical Treatment of Giant Cavernous Hemangioma Liver
In the past five years, 16 adults (10 females, age 25–61 years, mean 48) with giant cavernous
hemangioma of the liver measuring 15–31 cm (mean-19) underwent surgery in a single Institution.
Diagnosis was made with the help of multimodal investigations– ultrasound (US), computed tomography
(CT), hepatic angiography, hepatic scintigraphy and fine needle biopsy. Ultrasound and CT had
sensitivities of 69% and 82% respectively. Fourteen had preoperative selective hepatic artery embolization
to study its effect on operative blood loss. Indication for surgery in all cases was a large abdominal
mass with varying severity of pain. In addition, 5 had hemetological and/or coagulation abnormalities,
hemobilia in and pyrexia in 1. Seven left lobectomies, 3 left lateral segmentectomies, 2 right
lobectomies, 2 right trisegmentectomies and 4 non-anatomical resections of to 3 segments were
performed. Postoperative complications developed in 25% with no operative mortality. Preoperative
selective hepatic artery embolization helped to decrease the operative hemorrhage in 13 (mean blood
loss– 1146 ml). In two cases severe bleeding required use of Cell-saver and massive donor blood
transfusion. Our results suggest use of preoperative selective hepatic artery embolization and Cell-saver
as an adjunct to the liver resection for these vascular tumors
Is Cohabitation an Alternative to Marriage in Russia?
Declining marriage rates and increasing cohabitation rates in modern Russia have become a trend that many scholars have observed and tried to explain through the perspective of the Second Demographic Transition. Our research is another attempt to understand these changes and to answer the question on the nature of cohabitation in Russia. We aimed to find the difference between some patterns of matrimonial events and to define the nature of cohabitations in Russia. For these purposes, we applied descriptive statistics and Event History Analysis. We also suggested a logical scheme of the ways of development of the first cohabitations. We observed the opposite trends of matrimonial behavior: the younger Russian people are, the higher their probability of starting of the first cohabitation and the lower their risk to have the first marriage. Our analysis showed that a cohabitation is not yet a complete alternative to marriage, but it has a possibility of becoming it for younger generations.Quetelet Journal, forthcomingСнижение количества браков и увеличение количества сожительств в современной России стало тенденцией, которую многие ученые наблюдали и пытались объяснить через призму второго демографического перехода. Наше исследование является еще одной попыткой понять эти изменения и ответить на вопрос о природе сожительства в России. Мы стремились найти разницу между некоторыми моделями супружеских событий и определить характер сожительств в России. Для этих целей, мы применили описательную статистику и анализ истории событий. Мы также предложили логическую схему путей развития первых сожительств. Мы наблюдали противоположные тенденции супружеского поведения: чем моложе русские, тем выше вероятность совместного проживания и ниже риск первого брака. Наш анализ показал, что сожительство не полная альтернатива браку, но у него есть возможность стать таковой для младших поколений
ИНСЕКТОАКАРИЦИДНАЯ ЭФФЕКТИВНОСТЬ ОШЕЙНИКОВ «БАРС» ПРОТИВ ЭКТОПАРАЗИТОВ
It is developed new insektoakaricids preparations for control with ectoparasites (fleas, ixodoidea ticks). Insektoakaricids collars № 1, 2, 3, and also insektoakaricids collars (deltametrin) have shown high insektoakaricids action and long-term effect (from 4 till 6 weeks).Для борьбы с эктопаразитами (блохи, иксодовые клещи) разработаны новые инсектоакарицидные пре-параты. Инсектоакарицидные ошейники № 1, 2 и 3, а также инсектоакарицидные ошейники на основе дельтаметрина показали высокое инсектоакарицидное действие и эффект в течение 4–6 недель
The Outer Tracker Detector of the HERA-B Experiment Part I: Detector
The HERA-B Outer Tracker is a large system of planar drift chambers with
about 113000 read-out channels. Its inner part has been designed to be exposed
to a particle flux of up to 2.10^5 cm^-2 s^-1, thus coping with conditions
similar to those expected for future hadron collider experiments. 13
superlayers, each consisting of two individual chambers, have been assembled
and installed in the experiment. The stereo layers inside each chamber are
composed of honeycomb drift tube modules with 5 and 10 mm diameter cells.
Chamber aging is prevented by coating the cathode foils with thin layers of
copper and gold, together with a proper drift gas choice. Longitudinal wire
segmentation is used to limit the occupancy in the most irradiated detector
regions to about 20 %. The production of 978 modules was distributed among six
different laboratories and took 15 months. For all materials in the fiducial
region of the detector good compromises of stability versus thickness were
found. A closed-loop gas system supplies the Ar/CF4/CO2 gas mixture to all
chambers. The successful operation of the HERA-B Outer Tracker shows that a
large tracker can be efficiently built and safely operated under huge radiation
load at a hadron collider.Comment: 28 pages, 14 figure
The Outer Tracker Detector of the HERA-B Experiment. Part II: Front-End Electronics
The HERA-B Outer Tracker is a large detector with 112674 drift chamber
channels. It is exposed to a particle flux of up to 2x10^5/cm^2/s thus coping
with conditions similar to those expected for the LHC experiments. The
front-end readout system, based on the ASD-8 chip and a customized TDC chip, is
designed to fulfil the requirements on low noise, high sensitivity, rate
tolerance, and high integration density. The TDC system is based on an ASIC
which digitizes the time in bins of about 0.5 ns within a total of 256 bins.
The chip also comprises a pipeline to store data from 128 events which is
required for a deadtime-free trigger and data acquisition system. We report on
the development, installation, and commissioning of the front-end electronics,
including the grounding and noise suppression schemes, and discuss its
performance in the HERA-B experiment
Monitoring international migration flows in Europe. Towards a statistical data base combining data from different sources
The paper reviews techniques developed in demography, geography and statistics that are useful for bridging the gap between available data on international migration flows and the information required for policy making and research. The basic idea of the paper is as follows: to establish a coherent and consistent data base that contains sufficiently detailed, up-to-date and accurate information, data from several sources should be combined. That raises issues of definition and measurement, and of how to combine data from different origins properly. The issues may be tackled more easily if the statistics that are being compiled are viewed as different outcomes or manifestations of underlying stochastic processes governing migration. The link between the processes and their outcomes is described by models, the parameters of which must be estimated from the available data. That may be done within the context of socio-demographic accounting. The paper discusses the experience of the U.S. Bureau of the Census in combining migration data from several sources. It also summarizes the many efforts in Europe to establish a coherent and consistent data base on international migration.
The paper was written at IIASA. It is part of the Migration Estimation Study, which is a collaborative IIASA-University of Groningen project, funded by the Netherlands Organization for Scientific Research (NWO). The project aims at developing techniques to obtain improved estimates of international migration flows by country of origin and country of destination
