Individual personality traits as predictors of intra-organizational vertical career growth of employees

The paper is devoted to the research on the influence of individual personality traits on the success of intra-organizational vertical career growth of employees, the indicator of which is the promotion of employees in their position (status) in the organization, taking into account their speed of passing the career levels. The article analyzes the types of career, criteria and factors of career growth, including personality characteristics in the context of their influence on career processes. The article presents the results of an empirical study of the managers of JSC Concern Energomera, Stavropol (Russia), which determined the relationship between the success rate of intra-organizational vertical career growth and individual personality characteristics, manifested in the level of mental tension (anxiety, suspicion, inclination to risk, spontaneity and emotional sensitivity) and expressiveness. The authors did not find statistically significant contribution of regulatory properties and indicators of general mental abilities to distinguishing groups of employees with high and low indicators of vertical career growth. The averaged personal profiles of employees with high and low indicators of vertical career growth are presented.peer-reviewe

Comparison of large-angle production of charged pions with incident protons on cylindrical long and short targets

The HARP collaboration has presented measurements of the double-differential pi+/pi- production cross-section in the range of momentum 100 MeV/c <= p 800 MeV/c and angle 0.35 rad <= theta <= 2.15 rad with proton beams hitting thin nuclear targets. In many applications the extrapolation to long targets is necessary. In this paper the analysis of data taken with long (one interaction length) solid cylindrical targets made of carbon, tantalum and lead is presented. The data were taken with the large acceptance HARP detector in the T9 beam line of the CERN PS. The secondary pions were produced by beams of protons with momenta 5 GeV/c, 8 GeV/c and 12 GeV/c. The tracking and identification of the produced particles were performed using a small-radius cylindrical time projection chamber (TPC) placed inside a solenoidal magnet. Incident protons were identified by an elaborate system of beam detectors. Results are obtained for the double-differential yields per target nucleon d2 sigma / dp dtheta. The measurements are compared with predictions of the MARS and GEANT4 Monte Carlo simulations.Comment: 43 pages, 20 figure

Применение хвои и скорлупы кедрового ореха в кормлении сельскохозяйственных животных и птицы (обзор)

Forests cover one-third of the planet’s land surface. Forests are essential for maintaining a clean environment, food security and biodiversity. Forests are also a source of food for animals. In the processing of forest resources, the forest industry accumulates various forest biomass wastes containing valuable and nutritious biologically active substances. The article provides an overview of the current state of the art in applying forest industry waste to feed farm animals and poultry. The authors presented the characteristics of biological properties of plant forestry raw materials and described the mechanism of their action on the animal organism. The authors analysed the results of studies of domestic and foreign scientists on feeding animals and poultry with feed additives containing pine needles and pine nutshells. The authors also characterised the possible advantages and disadvantages of using feed additives. The analysis of Russian and foreign scientific literature in the area under study has shown that forest industry waste in feed production and animal feeding is relevant as the available fodder base does not always allow to satisfy the need of animals for nutrients and biologically active substances. It has been noted that pine needles are used worldwide as a feed additive, but in the countries with the most significant areas of forests and developed forest industry, their use is the most common and effective. The use of cedar nut shells in the feeding of farm animals and poultry is most produced in Russia, while this area is underdeveloped in the world. The literature review has confirmed that using forest industry wastes such as pine nut needles and shells in animal feed production is promising livestock production.Леса покрывают одну третью часть поверхности суши планеты и играют важнейшую роль в поддержании чистоты окружающей среды, продовольственной безопасности населения и сохранении биологического разнообразия, а также выступают в качестве кормового источника для животных. При переработке лесных ресурсов в лесной промышленности накапливается большое количество различных отходов лесной биомассы, содержащих ценные и питательные биологически активные вещества. В статье представлен обзор современного состояния применения отходов лесной промышленности в кормлении сельскохозяйственных животных и птицы. Представлена характеристика биологических свойств растительного лесного сырья, описан механизм его действия на животный организм. Проведен анализ результатов исследований отечественных и зарубежных ученых по скармливанию кормовых добавок, содержащих хвою и скорлупу кедрового ореха, животным и птице, охарактеризованы возможные преимущества и недостатки их использования. Анализ российской и зарубежной научной литературы в исследуемой области показал, что использование отходов лесной промышленности в кормопроизводстве и кормлении животных актуально, поскольку имеющаяся кормовая база не всегда позволяет удовлетворить потребность животных в питательных и биологически активных веществах. Отмечено, что хвою применяют в мире в качестве кормовой добавки повсеместно, однако в странах с наибольшими площадями лесов и при развитой лесной промышленности ее использование наиболее распространено и эффективно. Использование скорлупы кедрового ореха в кормлении сельскохозяйственных животных и птицы наиболее развито в России, в то время как в мире это направление развито слабо. Проведенный обзор литературы подтвердил, что применение в кормопроизводстве отходов лесной отрасли, таких как хвоя и скорлупа кедрового ореха, перспективно для животноводства

Absolute Momentum Calibration of the HARP TPC

In the HARP experiment the large-angle spectrometer is using a cylindrical TPC as main tracking and particle identification detector. The momentum scale of reconstructed tracks in the TPC is the most important systematic error for the majority of kinematic bins used for the HARP measurements of the double-differential production cross-section of charged pions in proton interactions on nuclear targets at large angle. The HARP TPC operated with a number of hardware shortfalls and operational mistakes. Thus it was important to control and characterize its momentum calibration. While it was not possible to enter a direct particle beam into the sensitive volume of the TPC to calibrate the detector, a set of physical processes and detector properties were exploited to achieve a precise calibration of the apparatus. In the following we recall the main issues concerning the momentum measurement in the HARP TPC, and describe the cross-checks made to validate the momentum scale. As a conclusion, this analysis demonstrates that the measurement of momentum is correct within the published precision of 3%.Comment: To be published by JINS

Forward production of charged pions with incident π±\pi^{\pm} on nuclear targets measured at the CERN PS

Measurements of the double-differential $\pi^{\pm}$ production cross-section in the range of momentum 0.5 \GeVc \leq p \le 8.0 \GeVc and angle 0.025 \rad \leq \theta \le 0.25 \rad in interactions of charged pions on beryllium, carbon, aluminium, copper, tin, tantalum and lead are presented. These data represent the first experimental campaign to systematically measure forward pion hadroproduction. The data were taken with the large acceptance HARP detector in the T9 beam line of the CERN PS. Incident particles, impinging on a 5% nuclear interaction length target, were identified by an elaborate system of beam detectors. The tracking and identification of the produced particles was performed using the forward spectrometer of the HARP detector. Results are obtained for the double-differential cross-sections ${{\mathrm{d}^2 \sigma}}/{{\mathrm{d}p\mathrm{d}\Omega}}$ mainly at four incident pion beam momenta (3 \GeVc, 5 \GeVc, 8 \GeVc and 12 \GeVc). The measurements are compared with the GEANT4 and MARS Monte Carlo simulationComment: to be published on Nuclear Physics

Large-angle production of charged pions by 3 GeV/c - 12 GeV/c protons on carbon, copper and tin targets

A measurement of the double-differential $\pi^{\pm}$ production cross-section in proton--carbon, proton--copper and proton--tin collisions in the range of pion momentum 100 \MeVc \leq p < 800 \MeVc and angle 0.35 \rad \le \theta <2.15 \rad is presented. The data were taken with the HARP detector in the T9 beam line of the CERN PS. The pions were produced by proton beams in a momentum range from 3 \GeVc to 12 \GeVc hitting a target with a thickness of 5% of a nuclear interaction length. The tracking and identification of the produced particles was done using a small-radius cylindrical time projection chamber (TPC) placed in a solenoidal magnet. An elaborate system of detectors in the beam line ensured the identification of the incident particles. Results are shown for the double-differential cross-sections at four incident proton beam momenta (3 \GeVc, 5 \GeVc, 8 \GeVc and 12 \GeVc)

КОМПЛЕКСНОЕ ПРИМЕНЕНИЕ МЕТОДОВ ОПТИЧЕСКОЙ ДИАГНОСТИКИ ПРИ НЕСПЕЦИФИЧЕСКОМ ЯЗВЕННОМ КОЛИТЕ

Abstract. Our results suggest that the combined use of optical coherent tomography (OCT) and fluorescence diagnosis helps to refine the nature and boundaries of the pathological process in the tissue of the colon in ulcerative colitis. Studies have shown that an integrated optical diagnostics allows us to differentiate lesions respectively to histology and to decide on the need for biopsy and venue. This method is most appropriate in cases difficult for diagnosis. Резюме. Cовместное использование оптической когерентной томографии (ОКТ) и флюоресцентной диа- гностики способствует уточнению характера и границ патологического процесса в ткани толстой кишки при неспецифическом язвенном колите. Исследования показали, что комплексная оптическая диагностика позволяет дифференцировать патологические изменения соответственно гистологической картине и решить вопрос о необходимости биопсии и месте ее проведения. Применение данного метода наиболее целесообразно в трудных диагностических случаях.

МАНУАЛЬНАЯ ТРОМБОЭКСТРАКЦИЯ У БОЛЬНЫХ С ОСТРЫМ ИНФАРКТОМ МИОКАРДА С ПОДЪЕМОМ СЕГМЕНТА ST

Distal coronary artery embolism (DCAE) is a serious complication  of percutancous coronary intervention (PCI).  Distal embolism causes a significant reduction or even blockage of myocardial perfusion, despite the fact that blood flow in the occluded segment of the infarct-related artery is restored. According to various sources, the incidence of distal embolization associated with PCI is about 25%. Various techniques, both invasive and non-invasive, have been developed for identifying distal embolism. DCAE during PCI is prevented with the help of different devices, among which those for thromboextraction are the most reliable. The devices can be divided into manual and rheolytic.Дистальная эмболия коронарных артерий (ДЭКА) — серьезное осложнение чрескожного коронарного вмешательства (ЧКВ). Дистальная эмболия приводит к заметному снижению перфузии миокарда, вплоть до полного ее отсутствия, несмотря на восстановление кровотока в окклюзированном сегменте инфарктсвязанной артерии. Частота развития дистальной эмболии при ЧКВ, по разным данным, составляет около 25%. Для выявления дистальной эмболии разработаны различные методики, как инвазивные, так и неинвазивные. С целью предотвращения ДЭКА во время ЧКВ существуют разные устройства. Наиболее зарекомендованные – это устройства для тромбоэкстракции. Их можно разделить на мануальные и реолитические. Реолитические тромбоэкстракторы (с наличием механизированной части) не показали преимуществ по сравнению с обычным ЧКВ. Другое важное направление — мануальная тромбоэкстракция. Все устройства для мануальной тромбоэкстракции схожи по строению, но различаются материалом, кончиком, а также диаметром просвета. Крупные исследования по мануальной тромбоэкстракции не показали преимуществ этого устройства перед стандартным ЧКВ. Однако в настоящее время еще остается ряд вопросов по эффективности тромбоэкстракции.

Measurement of the production of charged pions by protons on a tantalum target

A measurement of the double-differential cross-section for the production of charged pions in proton--tantalum collisions emitted at large angles from the incoming beam direction is presented. The data were taken in 2002 with the HARP detector in the T9 beam line of the CERN PS. The pions were produced by proton beams in a momentum range from 3 \GeVc to 12 \GeVc hitting a tantalum target with a thickness of 5% of a nuclear interaction length. The angular and momentum range covered by the experiment (100 \MeVc \le p < 800 \MeVc and 0.35 \rad \le \theta <2.15 \rad) is of particular importance for the design of a neutrino factory. The produced particles were detected using a small-radius cylindrical time projection chamber (TPC) placed in a solenoidal magnet. Track recognition, momentum determination and particle identification were all performed based on the measurements made with the TPC. An elaborate system of detectors in the beam line ensured the identification of the incident particles. Results are shown for the double-differential cross-sections ${{\mathrm{d}^2 \sigma}} / {{\mathrm{d}p\mathrm{d}\theta}}$ at four incident proton beam momenta (3 \GeVc, 5 \GeVc, 8 \GeVc and 12 \GeVc). In addition, the pion yields within the acceptance of typical neutrino factory designs are shown as a function of beam momentum. The measurement of these yields within a single experiment eliminates most systematic errors in the comparison between rates at different beam momenta and between positive and negative pion production.Comment: 49 pages, 31 figures.

Measurements of the double-differential $\pi^{\pm}$ production cross-section in the range of momentum 100 \MeVc \leq p < 800 \MeVc and angle 0.35 \rad \leq \theta < 2.15 \rad in proton--beryllium, proton--aluminium and proton--lead collisions are presented. The data were taken with the HARP detector in the T9 beam line of the CERN PS. The pions were produced by proton beams in a momentum range from 3 \GeVc to 12.9 \GeVc hitting a target with a thickness of 5% of a nuclear interaction length. The tracking and identification of the produced particles was performed using a small-radius cylindrical time projection chamber (TPC) placed inside a solenoidal magnet. Incident particles were identified by an elaborate system of beam detectors. Results are obtained for the double-differential cross-sections at six incident proton beam momenta (3 \GeVc, 5 \GeVc, 8 \GeVc, 8.9 \GeVc (Be only), 12 \GeVc and 12.9 \GeVc (Al only)) and compared to previously available data
