    The article considers the importance of an effective risk management system in the conditions of uncertainty and instability for Russian companies. It concludeis that it is necessary to implement such a system to improve the management efficiency of a modern organization, using the example of PJSC “Geotek Seismo Razvedka”. The advantages and disadvantages of the existing risk management policy are identified. The authors suggest measures to improve the risk management system for this company. The article proposes to develope (define) the key risk indicators, offers to intensify risk management activities in the field of risk monitoring. To do this, the authors recommend to implement the Omnitracker Risk  Management software product as a system for automating the company’s risk management processes. The advantages of this product are considered, and a schedule for the implementation of Omnitracker Risk Management in PJSC “Geotek Seismo Razvedka”is developed

    The paper presents the results of experimental study of electronic structure of RbPb2Cl5 and KPb2Cl5 laser crystals performed by the optical and photoelectron spectroscopy methods. On the basis of the optical absorption and low-temperature reflection spectra of these crystals we have determined the energy positions of the edges of the low-energy tail of the host absorption, the positions of the first excitonic absorption peaks, and exciton binding energies. The bandgap widths of these crystals at 8 K were estimated as Eg = 4.83 and 4.79 eV, respectively. Qualitative and quantitative analysis of RbPb2Cl 5 and KPb2Cl5 crystals were made on the basis of the core states photoelectron spectra. The elemental composition of the (0 0 1) surfaces of the crystals, the chemical state of the host atoms, the electronic structure of the valence band of the crystals were discussed on the basis on the spectroscopic data. © 2012 Elsevier B.V.

    Well drilling machines should have as high efficiency factor as it is possible. This work proposes factors that are affected by change of input signal pulse curve. A series of runs are conducted on mathematical model of hydraulic-powered pulse machine. From this experiment, interrelations between input pulse curve and construction parameters are found. Results of conducted experiment are obtained with the help of the mathematical model, which is created in Simulink Matlab

    Lung cancer remains the leading cause of cancer mortality worldwide. Solid organ transplant recipients are at risk of developing malignant tumors, including lung cancer, due to long-term use of immunosuppressive drugs. Development of cancer, including lung cancer, in this patient cohort, has a number of peculiarities. Moreover, malignant tumors in these patients are difficult to treat and have a poorer prognosis. This review presents a study of the issues concerning the mechanisms of lung cancer development, screening methods and treatment in solid organ transplant recipients.Рак легкого остается ведущей причиной смерти в популяции среди всех злокачественных новообразований. Реципиенты солидных органов находятся в группе риска развития злокачественных новообразований, включая рак легкого, за счет длительного приема иммуносупрессивных препаратов. Развитие онкологических заболеваний, включая рак легкого, у этой категории больных отличается рядом особенностей. Кроме того, злокачественные новообразования у реципиентов солидных органов трудно поддаются лечению и имеют худший прогноз. Изучению вопросов, касающихся механизмов развития, методов скрининга и лечения рака легкого у реципиентов солидных органов, посвящен данный обзор

    Bronchial complications are among the main causes of impairing postoperative period and thansplant failure. Severe bronchial complications are very rare but have a high mortality rate. Light forms decrease transplant function and while progressing can leads to life-threatening conditions without required treatment. Nowadays there is a huge necessity in classification of diagnostic and bronchial complications treatment on different terms after lung transplantation. Methods of observation bronchoscopy and interventional bronchology are allowing us to realize prevention, diagnostic and treatment bronchial complications.Бронхиальные осложнения являются одной из основных причин тяжелого течения послеоперационного периода и неблагоприятных исходов у реципиентов донорских легких. Несмотря на относительно низкую частоту тяжелых форм бронхиальных осложнений, последние определяют высокую летальность, в то время как легкие формы бронхиальных осложнений без необходимого лечения значительно ухудшают функцию трансплантата и качество жизни реципиента, прогрессируя, приводят к жизнеугрожающим состояниям. Несмотря на обилие научных публикаций, существует потребность в систематизации подходов к диагностике и лечению бронхиальных осложнений на разных сроках после трансплантации, оценке роли обсервационной бронхоскопии и методов интервенционной бронхологии в профилактике, диагностике и лечении бронхиальных осложнений

    Aim. Determination of the level of zinc and its fractions, as well as the enzyme neutrophilic elastase and albumin in persons suffering from chronic obstructive pulmonary disease (COPD), as well as smoking actively and passively. Materials and methods. The study involved 30 patients with a diagnosis of COPD and 90 healthy persons (60 of them smoking at the present time, 30 - no) who underwent spirometry and determination of zinc levels and its pools, albumin, and neutrophil elastase. All data are subject to statistical processing. Results. It is determined that the studied parameters differ significantly in the groups of smokers with COPD, healthy smokers and non-smokers, and correlate with the volume of forced exhalation for 1 second as a percentage of the due. Conclusion. The revealed regularities make it possible to consider the indicator "share of bound zinc fraction" introduced in the study as a screening criterion in diagnosing COPD in smokers

    Lung transplantation is the final treatment option for end-stage lung disease when all possible conservative treatment is exhausted. According to the International Society for Heart and Lung transplantation Registry, more than 60000 lung transplantations have been performed worldwide. The early post-transplant period following lung transplantation remains critical because of numerous complications. These complications can be divided into several groups. These are surgical complications, primary graft dysfunction and acute rejection, infection, cardiovascular, abdominal and renal disorder. This complications may result in significant morbidity, mortality and limit short and long-term survival. The aim of this review is to describe the main postoperative complications in first month after lung transplantation in the world practice.Трансплантация легких является последним возможным вариантом терапии терминальных стадий заболеваний легких в случае неэффективности консервативной терапии. Согласно регистру Международного общества трансплантации сердца и легких, в мире выполнено более 60 000 трансплантаций легких. Тяжесть послеоперационного периода обусловлена высокой частой послеоперационных осложнений. Осложнения послеоперационного периода могут быть разделены на несколько групп: хирургические осложнения, первичная дисфункция трансплантата и острое отторжение, сердечно-сосудистые, абдоминальные и почечные осложнения. Цель данного обзора литературы - анализ основных осложнений в раннем послеоперационном периоде после трансплантации легких в мировой практике
