PROBLEMS AND WAYS OF EFFECTIVE DEVELOPMENT OF DEEP OIL DEPOSITS WITH ABNORMALLY HIGH RESERVOIR PRESSURES

Currently, due to the reduced fund of prospective structures at shallow depths (2500-3000 m) annually increased amount of discovered and put in development oil deposits lying at greater depths. According to published works in various oil and gas provinces of the world within the depth interval 4500-8100m already being developed more than 1000 fields [1]Currently, due to the reduced fund of prospective structures at shallow depths (2500-3000 m) annually increased amount of discovered and put in development oil deposits lying at greater depths.

Methodology for Developing Information-Analytic Competency of Future Primary Class Teachers

In modern conditions of the emergence of a global information society, the role of information in the training of a future specialist is significantly increasing. The idea is increasingly gaining ground in people's minds that the future strategic potential of society will not be energy resources, but information and scientific knowledge. Information becomes the main resource for the scientific, technical, and socio-economic development of society, significantly influences the accelerated development of science, technology, and various industries, and plays a significant role in the process of modernization of education. &nbsp

CONCERNING FORECASTING OF THE RESERVOIR TYPES OF DEEP SEATED OIL DEPOSIT

It’s recommended to utilize the proposed classification of reservoir types selection for the fields conditions of Fergana depression in the well drilling and site development. For increasing field development efficiency in depth of “bad” and “ugly” reservoirs it’s required more advanced specialized technologies that keep stability and wall-building properties of container rocks during filtration of formation fluids.It’s recommended to utilize the proposed classification of reservoir types selection for the fields conditions of Fergana depression in the well drilling and site development.

Синтез и превращения пиразолопиримидинкарбогидразидов

Pyrazolopyrimidinecarbohydrazides were synthesised by hydrazinolysis of the ester group in carbethoxypyrazolopyrimidines. Functionalisation of the hydrazide group in the obtained compounds resulted in the formation of both annulated systems and of linear pyrazolopyrimidotriazepinones, pyrazolindiones, dimethylpyrazolines.Путем гидразинолиза сложноэфирной группы в карбэтоксипиразолопиримидинах получены пиразолопиримидинкарбогидразиды. Функционализация гидразидной группы полученных соединений привела к образованию как аннелированных пиразолопиримидотриазепиноновых систем, так и линейных пиразолопиримидинзамещенных пиразолиндионов, диметилпиразолинов

ОСОБЕННОСТИ ФУНКЦИОНИРОВАНИЯ АРАБСКО-ПЕРСИДСКИХ ЗАИМСТВОВАНИЙ В СОВРЕМЕННОМ ТАТАРСКОМ ЯЗЫКЕ

Some semantic features of Arabic-Persian borrowings are analyses in this article, which are in current process of intensification in the Tatar literary language of the late 20th and early 21st centuries. Some of these eastern borrowings are acquired new meanings or some features of meanings in contemporary Tatar language, which do not exist in the source language; some of them are used in new meanings for determination of new realities or for changing some international terms of the Russian language. Polysemantic foreign words usually have only one meaning, which is actual in the present.В статье анализируются семантические особенности арабско-персидских заимствований, которые переживают процесс активизации в татарском литературном языке конца XX - начала XXI вв. Часть таких заимствований приобрела в современном татарском языке новые значения или оттенки значений, отсутствующие в языке-источнике, часть употребляется в новых значениях для обозначения новых реалий или замены русско-интернациональных терминов. Многозначные иноязычные слова обычно употребляются только в одном актуальном для современности значении

POSSIBLE PREDICTORS OF ATRIAL FIBRILLATION RECURRENCE IN LONG-TERM PROPHYLACTIC PROPAFENONE THERAPY

Aim. To identify possible predictors of atrial fibrillation (AF) recurrence in 6-month prophylactic propafenone therapy. Material and methods. Patients (n=63; aged 52.2±12.6 years; 25.4% women) with frequent AF recurrences who restored sinus rhythm with propafenone, were included into the study. Paroxysmal AF was observed in 84.1% of patients, and persistent AF — in 15.9% of patients. ECG, transthoracic echocardiography , chest radiography with the calculation of cardio-thoracic index (CTI) was performed at baseline. All patients received rpropafenone therapy (450–600 mg/day) during 6 months after sinus rhythm conversion. ECG and 24-hours ECG monitoring were performed in 1, 3 and 6 months of the therapy. Patients with 70–100% reduction in AF recurrence rate were included into the 1-st group, and patients with &lt;70% reduction – into the 2-nd group. Results. 92%, 88.5% and 78% of patients were included into the group 1 after 1, 3 and 6 months of follow up, respectively. AF recurrences were observed 4.5, 3.8, and 1.7 times more often in women than these in men after 1, 3 and 6 months, respectively , (p&gt;0.05). Mean age of patients in the group 2 was significantly older than this in patients of the group 1 (p&lt;0.05). CTI, left atrium size and volume, interventricular septum thickness (IVST) were significantly larger in group 2. Myocardium mass of the left ventricle (MMLV) after 6 months of therapy was larger by 13.9% in patients of the group 2 vs this in patients of the group 1 (p&lt;0.05). Conclusion. Insufficient preventive effect of propafenone was observed in 8%, 11.5% and 22% of patients in 1, 3 and 6 months of the follow-up, respectively. Propafenone prophylactic efficacy was slightly higher in men and younger patients. Patients with poor preventive effect of propafenone had a significantly larger baseline CTI, size and volume of the left atrium, IVST, and MMLV.</p
