Актуальность работы обусловлена необходимостью модернизации различного оборудования на многих старых газокомпрессорных станциях в связи с постройкой газопровода «Сила Сибири». Цель работы: провести анализ пуска электропривода компрессорной установки перекачки природного газа после замены синхронного двигателя на асинхронный. Данная установка является частью большой системы газоснабжения Сибири и Дальнего Востока. Методы: анализ и синтез замкнутых электромеханических систем, математическое описание электропривода переменного тока компрессора в осях x, y, 0 с законом управления U/f2 и учётом особенностей работы на «дожим» природного газа в системе его перекачки. Кроме того, были учтены изменения внутренних параметров исполнительного двигателя (фирмы Siemens типа 1TA2832-4AU01-Z) при увеличении частоты питающего напряжения в пределах от 70 до 150 Гц, а именно уменьшение активных и индуктивных сопротивлений обмоток статора и ротора на 8–12 %, и проведена оценка влияния частоты на динамические показатели электропривода компрессора. Результаты. Получили полную автоматизацию подачи и перекачки природного газа, установили, что изменение частоты питающего напряжения в два раза приводит к увеличению пускового момента на 13 %. Установили, что частота питающего напряжения, равная 136 Гц, является наиболее оптимальной, т. к. позволяет снизить рабочие токи в цепях обмоток статора исполнительного двигателя и устранить проблему бросков токов при пуске, что, в свою очередь, позволило уменьшить потребление электроэнергии в компрессорном цехе на 15–18 %.

Актуальность исследования обусловлена необходимостью объяснения высокой заболеваемости населения в районах распространения радиоактивных пород и почв. Исследование выполнено в рамках нового научного направления – медицинской геологии. Целью работы является изучение масштабов радоновыделений в районах выхода на поверхность высокорадиоактивных гранитов, оценка их радиоэкологической опасности и медико-биологических последствий. Объекты: геохимический и минералогический состав образцов гранитов, кор выветривания и почв, масштабы радоновыделений и частота заболеваемости в различных областях мира (г. Чжухай в китайской провинции Гуандун; г. Эшасьер во французском регионе Овернь) и Сибирского региона (г. Белокуриха Алтайского края; пгт. Колывань Новосибирской области). Методы. В рамках исследования применялся широкий комплекс методов, включающий инструментальный нейтронно-активационный, рентгенофазовый анализы, гамма-спектрометрию, осколочную радиографию, электронную микроскопию, экспрессное измерение объёмной активности радона, расчет потока плотности радона, эквивалентной эффективной дозы и частоты вновь выявленных заболеваний (incidence). Результаты. Проведено обобщение данных по воздействию ионизирующего излучения на организм человека. По результатам геохимических, минералогических, радиоэкологических и медико- статистических исследований выявлено, что в процессах коро- и почвообразования радионуклиды высвобождаются из структурных решеток акцессорных минералов и сорбируются на глинистых минералах. Данный процесс способствует повышению радоновыделений и радиационного фона. Дано объяснение возможных связей повышенных концентраций радионуклидов в подстилающих породах, почвах и высокой активности газа радона с показателями заболеваемости населения. При сопоставлении первичных показателей онкозаболеваемости у всех групп населения с общероссийскими и мировыми показателями отмечаются превышения уровня во всех исследуемых районах. К территориям «риска» по частоте заболеваемости раком легкого можно отнести Белокуриху в Алтайском крае и Колывань в Новосибирской области; раком носоглотки – провинцию Гуандун; раком кроветворной ткани – Колывань; анемиями – Гуандун; по врожденным порокам развития – Гуандун и Колывань.

Актуальность. В настоящее время для прогнозирования глобальных климатических изменений особое значение имеет исследование природных механизмов функционирования арктической биогеохимической экосистемы с применением различных методов и аналитических подходов. Органическое вещество современных донных осадков, аккумулирующее гетерогенные сигналы различных процессов транспорта и трансформации углерода, является индикатором уникальных особенностей седиментогенеза и диагенеза осадков. Использование наборов высокоточных геохимических инструментов позволяет получить важную информацию о вкладе аллохтонной и автохтонной компоненты в состав органического вещества и таким образом внести вклад в понимание отдельных элементов современного арктического цикла углерода. Цель исследования заключается в определении литологических и органо-геохимических особенностей отложений, накопленных в специфических лагунных условиях прибрежной части моря Лаптевых (Ивашкина лагуна, Быковский полуостров). Материалы и методы. Объектом исследования был выбран разрез осадков в районе дельты реки Лена. Для оценки изменчивости молекулярного состава органического вещества в процессе накопления толщ осадков был исследован 18-метровый интервал керна скважины VD-13, пробуренной в центральной части Ивашкиной лагуны во время весенней арктической экспедиции 2013 г. Для образцов были определены их гранулометрические характеристики, а также проведены пиролитические и хромато-масс-спектрометрические исследования. Показано, что повышенное содержание органического углерода (Сорг) в разрезе приурочено к пелитовой фракции осадков. Распределение н-алканов характеризуется доминированием высокомолекулярных нечетных гомологов, что указывает на повсеместно определяющий вклад высшей наземной растительности в формирование органического вещества, аккумулируемого в осадках. Тем не менее, вклад потенциально миграционной органической компоненты не исключен, так как для ряда образцов отмечается присутствие низкомолекулярной фракции н-алканов. Результаты пиролитического анализа образцов указывают на резкую изменчивость содержания Сорг и летучих органических соединений с глубиной.

Background: Hyperphosphatemia has become one of the main causes of death in CKD patients on HD. Thus, correction and prevention of hyperphospatemia is a major component in the management of HD patients. High protein diet in HD patients may lead to increased serum phosphate level due to mineral metabolism disorder associated with decreased glomerular filtration rate. In addition, high protein intake often followed by high phosphate intake as high protein foods also contains high phosphate and may cause hyperphosphatemia. Meanwhile, reduction of protein intake to control phosphate level was associated with decreased health and nutritional status in CKD patients. Therefore, appropriate phosphate-protein ratio is essential to provide adequate protein intake and avoid hyperphosphatemia.Objective: To investigate the association between protein and phosphate intake, phosphate-protein ratio and blood phosphate level in CKD patients on routine HD.Method: The study used an analytic observational method with cross sectional design. There were 100 subjects involved in this study. Subject characteristics, protein and phosphate intake, phosphate-protein ratio and intake of phosphate binders were obtained through interview and 3 x24 hour food record. Serum phosphate level was analyzed by inorganic phosphorus quantification method. Food processor was used to analyze the intake of protein and phosphate. Bivariate and multivariate tests with 95% confidence interval were used to analyze the data.Results: Adequate protein intake was observed among 38% subjects, while 46% of them have excess phosphate intake.High phosphate-protein ratio was found in 20% subjects. Most subjects did not take phosphate binders regularly (61%) and have hyperphosphatemia (66%). The average protein intake, phosphate intake, phosphate-protein ratio, and blood phosphate level were 1.1 g/kg/d, 13.5 mg/kg/d, 12.8 mg/g, and 5.6 mg/dl, respectively. Bivariate test showed that there was a significant association between protein intake (p=0.037; RP=2.78), phosphate intake (p=0.005; RP=3.54), phosphate-protein ratio (p=0.045; RP=3.85), and blood phosphate level in CKD patients on routine HD. Multivariate analysis revealed that high phosphate intake and did not consume phosphate binders regularly were risk factors of hyperphosphatemia (p=0.000; OR=6.543; CI 95%:2.357-18.164 dan p=0.024; OR=3.413; CI 95%:1.179; R2=0.42).Conclusion: Consumtion of low phosphate foods and phosphate binders may reduce the risk of hyperphosphatemia in CKD patients on routine HD.

Background: The prevalence of obesity is markedly increasing, both in developed and developing countries. Whether physical activity contributes to the obesity in Indonesian adolescents is still unknown.Objective: To assess whether physical activity is associated with obesity in junior high school adolescents in Yogyakarta. Methods: A case control study was conducted in Yogyakarta Province in 2003. Subjects were 140 obese and 140 non- obese junior high school adolescents in Yogyakarta and Bantul, randomly chosen from an obesity survey performed previously. Pattern and duration of activity were assessed using IPAQ modified questionnaire. The activities were than sorted into light (sedentary), moderate and vigorous activities.Results: There was significant difference in the distribution sedentary activity between adolescents of Yogyakarta and Bantul (p<0.0001). The mean duration of sedentary activity in Yogyakarta was 12.4 hours/day while in Bantul was 11.0 hours/day. Obese adolescents spent longer time in sedentary activity than non-obese adolescents (p=0.002). The odds of being obese in adolescent whose sedentary activity was longer than 13 hours/day were almost doubled.Conclusions: Urban adolescents spent more time for sedentary activities than rural adolescents, so were obese adolescents. The association of sedentary activities to obesity is independent from other factors such as calorie intake and parental obesity status.

Background: The 2002-2003 IDHS shows that the presentation of breastfeeding within an hour after birth or early initiation in Indonesia is still low (38%). According to some studies, early initiation plays an important role in reducing infant mortality rate, determining the success of exclusive breastfeeding, preventing pre-lactation feeding, creating more intensive bonding between mother and baby. Some earlier studies state that delivery methods are related with early initiation. However, there have been some studies whose results are in contrast with those previous studies.Objective: To study the relationship between delivery methods and early initiation in Dr. Sardjito hospital, Yogyakarta.Method: This was an observational study with a cross-sectional study design through quantitative and qualitative approaches. Samples were postpartum women in Dr. Sardjito hospital as many as 100 respondents. Data were analyzed with univariable analysis using frequency distribution table, bivariable analysis using chi-square, and multivariable analysis using binary regression.Results: The proportion of early initiation of breastfeeding was three times greater in women who gave birth with normal delivery methods than women who gave birth with cesarean section (RR=3.1; 95% CI=1.42-6.89). Another factor that was related with early initiation of breastfeding was the support from health providers (RR=2.3; 95% CI=1.36-3.78). Meanwhile, women’s age, knowledge, parity, economic status, and mother’s disease were insignifcantly related with early initiation.Conclusion: The proportion of early initiation of breastfeeding was three times greater in women who gave birth with normal delivery methods than women who gave birth with cesarean section. Another factor that was related with early initiation of breastfeeding was the support from health providers.

Background: Obesity in adolescents has become health problem in Indonesia. Central obesity is associated with insulin resistance.Theoretically, insulin resistance will cause impaired glucose tolerance (IGT) and could develop into type 2 diabetes.Objective: The aim of this study were to evaluate the difference in IGT prevalence between central and non central obesity and to identify the risk factors associated with IGT. Method: A cross sectional study was conducted at 3 private secondary schools in Yogyakarta and recruited 62 obese female students aged 12-18 years.The subjects were classified into central obesity (BMI/U> +2SD and waist circumference > p90) and non central obesity based on anthropometric data. Fasting glucose and 2 hours after loading were measured in all subjects. Differences in the proportion of IGT between the two groups was calculated by Chi-square test and risk factors associated with IGT were calculated by multivariate logistic regression with 95% confidence interval.Result: Of 62 subjects, 14 of them have IGT and the prevalence of IGT was significantly higher in the central obesity group compared to non central obesity group (11/31 vs 3/31, p=0.03). Central obesity was found to be the only risk factor of IGT (OR=4.6; 95%CI: 1.04 to 20.24). Twenty one of the subjects were found to have impaired fasting glucose (IFG) (34%) and one subject (1.6 %) had IFG+IGT. There were no differences in the proportion of IFG between central and non central obesity groups. Conclusion: The prevalence of IGT in female students with central obesity was higher compared to those with non central obesity. A female student with central obesity had 4.6-fold risk of having IGT compared to those with non central obesity.
