Antoni Sagan was born in 1894 in Warsaw. He was a railwayman. Since the day of evacuation he kept a diary. Having lived for a month in a railway carriage, transferred from one place to another he chronicled events, experiences, thoughts. A part of his memoirs portreys economic side of life in these atypical conditions – prices and type of purchases as well as other expenses paid throughout the journey. They reveal author’s interests and likings, economic conditions of migrants and residents of the land traversed. The chronicle is of great historic value. Written during wartime it concerns a group of people united by a common fate of peregrination through the west part of the Russian Empire, entirely dependent on the incomprehensible decisions of the railway authorities. During the journey the author begins to see the signs of war, although he almost doesn’t experience it himself at this particular time. On the one hand the diary provides comments on the situation and events, on the other hand – describes and analyses the inner state of the narrator, his suffering about not having heard from his relatives left in Warsaw. After many ordeals Sagan delivered the railway assets he was given charge of and set off for Moscow.

Induction motors are important part of safe and efficient running of any industrial plant. These motors are often used in industrial applications thanks to their usability and their robustness. Faults and failures of induction machine can lead to excessive downtimes processes; generate large losses in revenues and long term maintenance. Early detection of motor abnormalities would help avoiding costly breakdowns. In this paper a diagnostic technique of induction motor broken rotor bars is presented. The applied method is the so-called Motor Current Signature Analysis (MCSA) which utilized the results of spectral analysis of the stator current. The broken rotor bars and rings will cause twice slip frequency side bands around the supplying frequency. The fault detection method consists in monitoring of stator phase current spectrum. Twice slip frequency side bands around the main frequency detected by spectral analysis is an indicator of the broken bars. The experimental results show the efficiency of the method.

Despite the fact that gas in the energy sector in Kazakhstan is of considerable importance, and its production scale is gradually extending, processing of associated gas has not reached an adequate dynamic. There is a need to find new ways of utilization of associated gas, introduction of new capacities enabling its processing and use. Therefore, the application of technological scheme with the use of modern compact gas turbine units for gas utilization, in conjunction with electrostatic precipitator for cleaning exhaust gas from the turbine, appears nowadays as the optimal option. This utilization of associated gas should not be a matter of prohibitions or task only of subsoil users, but should become a national priority. Only this complex approach could provide expected positive outcome.

The article describes the results from the comparative analysis of the acquired clinical skills’ assessment of undergraduate medical students in an innovative problem-based learning (PBL) and traditional curriculum. Attention is paid on the fact that even partially introduced in part of the early phases of the curriculum the PBL format of education has its impact on the future clinical functioning of the medical students. The PBL students performed better in comparison with their peers from the traditional track in regard to: the complete history taking as gathering data for the family history, available contacts with acute infectious diseases and known allergies to foods, drugs and other substances; and the use of more laboratory and other tests for building a diagnostic plan.

One of the components to control the international trade with endangered species of fauna and flora is the European Community border security. Because the trade of wild animals and plants crosses borders between countries, the effort to regulate it requires international cooperation to safeguard certain species from overexploitation. The CITES was conceived in the spirit of such cooperation. All import, export, re-export and introduction from the sea of species covered by the Convention has to be authorized through a licensing system. Each Party to the Convention must designate one or more Management Authorities in charge of administering that licensing system and one or more Scientific Authorities to advise them on the effects of trade on the status of the species. Implementing the CITES, the relevant European Community regulations and directives related to endangered wild animals and plants in international trade of the Republic of Lithuania, customs has become one of the main institutions to control the trade. For the global legal means to restrict the endangered species of wild animals and plants, their parts and products of their trade, import and export, the article examines the implementation of the customs activity of the CITES convention. Customs, while implementing endangered animal and plant protection, controls how to keep determined prohibitions, restrictions and special requirements. Efficiency of security depends on the cooperation of surveillance authorities and customs. International trade regulation methods are mainly associated with certain additional or specific requirements, e.g., a license, permit, certificate, conformity declaration and the like
