Abstract

Kazakhstan housing sector consumes about 11-13% of the electric power and 40% of made thermal energy (Housing and Utilities, 2017). On the average, residential houses in Kazakhstan consume three times more energy per unit of the area, than in the countries of Northern Europe. High level warmly of losses connected with the wear-and-tear of the equipment, as well as with necessity of execution of repair and update is noted. One of the most important directions in the area of power saving and increase of power efficiency is research and development of financial mechanisms for ultimate users stimulating attraction of investments to update of existing buildings for increase of their power efficiency. Not see-ing to realization of the complex of legislative initiatives and events, communicating Republic politics Kazakhstan in the area of power efficiency needs further perfecting, including in view of the best inter-national experience. In given article opportunities of increase of power efficiency of buildings are considered at the expense of application of innovative financial tools enabling to increase the profitability of capital investments in given sector and to lower expenses. In connection with that financial tools used in international practice are presented, analysis of deficiencies and advantages of existing tools is carried out. Practical importance of research consists in consideration of the most effective innovative financial tools in the area of power saving enabling to raise buildings power efficiency, efficiency of investments in given area. Experience of implementation of financial tools and mechanisms stimulate the increase of power efficiency of buildings in such countries as Netherlands, France, Italy, Slovakia, Estonia etc

Abstract

Objective: This study aimed to survey international experts in metabolic and bariatric surgery (MBS) to improve and consolidate perioperative interventions to prevent gastroesophageal reflux disease (GERD) and marginal ulcers (MU) after MBS. Background: Very important long-term complications after MBS include GERD, Barrett’s esophagus, and MU. Prevention might be fundamental to reduce the incidence, severe complications, and the increasing number of revisional bariatric surgeries. Methods: An international scientific team designed an online confidential questionnaire with 45 multiple-choice questions. The survey was sent to 110 invited experts and 96 of them (from 41 different countries) participated from 21 July 2022 to 4 September 2022. Results: Most experts (≥ 90%) prescribe postoperative acid suppression agents after MBS. Life-long proton pump inhibitors prophylaxis in smokers with avoidance of non-steroidal anti-inflammatory drugs are recommended by most of the experts (66%, 73%) after any type of gastric bypass. Two-thirds of experts (69%) perform Helicobacter pylori eradication prior to MBS. Two-thirds of experts (68%) routinely perform EGD and biopsy before MBS. Follow-up esophagogastroduodenoscopy (EGD) and timing threshold for revisional and conversional MBS were variable among experts. Conclusion: This expert survey underlines important perioperative interventions that reached a two-thirds consensus among MBS international experts. Variability in follow-up EGD, approach to complication management, and thresholds for revisional and conversional MBS emphasize the need for further researches and consensus guidelines.

Abstract

Bariatric surgery results in severe obese patients have been reviewed in the Azerbaijani population. The study involved results of the research performed with 119 severely obese patients [average age 40 19; average body mass index (BMI) 59.95+20.25 kg/m²] who undergone bariatric surgery, com- pared post-operative complications by different technical modification, and observed fatty liver dis- ease dynamics by examining BMI, diabetes, hypertension before operation and 1, 3, 6 and 12 months after operation. During the first 6 months, 109 (92.6%) patients who undergone laparoscopic sleeve gastrectomy (LSG) achieved average weight loss of 39.5+11.5 kg. In 10 (8.4%) patients who undergone gastric bypass surgery [2 (1.68%) patients - Ru Y gastric bypass, 6 (5.0%) patients - mini gastric by- pass, 1 (0.84%) patient - sleeve + Ru Y gastric bypass and 1 (0.84%) patient - sleeve+mini gastric by- pass], this indicator was 46±14 kg, and during the second 6 months effective weight loss was observed as in previous months, which equaled to 33.5+8.5 kg. Annual weight loss indicator was 71.5+23.5 kg for all surgeries. According to our study it can be concluded that unlike other methods, satisfactory weight loss in severely obese patients and consequently, improvement in comorbidities observed after laparoscopic sleeve gastrectomy (LSG) make this method more reliable.

Abstract

The book presents a detailed survey of light scattering studies of the daytime sky, the results of brightness and polarization measurements of the sky and observations of the horizontal transparency of the atmosphere. The problem of determining the albedo of localities from measurements of the air field of the descending radiation is studied and the apparatus for the measurement of the brightness and polarization of the sky in the ultraviolet region of the spectrum is described. A great deal of attention is given to the study of atmospheric aerosols, in particular, to an investigation of the pure light absorption in aerosols and the spectrum of the large fraction of the particles., Trans. from Akademiya Nauk Kazakhskoi SSR, Alma Ata.
