Type 1 diabetes mellitus is a condition associated with an increased risk of adverse perinatal outcomes such as spontaneous abortions, preterm birth, placental insufficiency, congenital malformations, and perinatal mortality. Diabetes mellitus combined with cardiovascular diseases in women during pregnancy often leads to hypertensive disorders and pre-eclampsia. The severity of the microvascular diabetic complications and frequency of hypoglycemic episodes, particularly in early pregnancy, are related to the risk of pre-eclampsia. We report the case of pregnancy and delivery of a live newborn in a 42-year-old woman with type 1 diabetes mellitus, pre-existing hypertension, heritable thrombophilia, and antiphospholipid syndrome. She had a 40-year history of type 1 diabetes mellitus with well-controlled diabetic nephropathy and retinopathy. The woman had been receiving continuous subcutaneous insulin therapy for the last five years, which allowed maintaining an appropriate glycemic control during pregnancy. Multidisciplinary supervision of course of pregnancy was carried out from the pre-gravidity stage until delivery and postpartum. In spite of the severe pre-eclampsia and preterm delivery by cesarean section at 36 weeks, she and newborn could avoid the intensive unit care and discharge from perinatal center without any complications.
WHY DO (WHITE) EVANGELICALS NEED TO BE REMINDED THAT BLACK LIVES MATTER?
Authors: Ybarrola Steven
Published: February 2019

This article explores the issues of race and the church in the United States today. Specifically, it examines why it is that Christians who represent the dominant racial category (i.e. white) have difficulty understanding the experiences of members of minority populations. As a Christian anthropologist, I explore this issue from three key anthropological concepts—culture, ethnocentrism, and cultural relativism. I then examine key theological issues related to Christianity and “otherness.” I conclude by bringing these two disciplines together as a way to address how they can lead to the renewing of the mind that Paul speaks of in Romans 12.

Актуальность. При решении обратных геофизических задач важное положение занимает задача построения объемных моделей петрофизических параметров. Наибольшие затруднения при разработке методов решения этой задачи определяются неоднородностью реальной геологической среды, а их точность – недостаточностью сетки скважинных наблюдений. Приведен новый метод, отличительной особенностью которого является совместное использование данных наземной сейсморазведки и геофизических исследований скважин. Он опирается на опыт геостатистического подхода и, решая описанные проблемы, использует предположение о том, что сейсмические и скважинные данные, измеренные в пределах одного геологического объекта, могут иметь схожие ковариационные свойства. Вопросы надежности и эффективности метода двойного крагинга ранее не были опубликованы, хотя их исследование требуется для практического применения метода. Одним из первых вопросов здесь является оценка влияния репрезентативности исходных данных. Цель работы: рассмотреть влияние репрезентативности исходных данных на качество моделирования методом двойного Крайгинга и возможные пути по разработке количественной меры оценивания репрезентативности. Объекты: синтезированная модель куба сейсмического атрибута; данные 3D МОГТ и ГИС Конторовичского месторождения Томской области. Методы: методы теории случайных функций, методы линейной алгебры, статистическое моделирование и вычислительный эксперимент. Результаты. Аналитически доказано, что при наличии репрезентативной выборки данных ошибка моделирования равна нулю. Аналитически и численно доказано, что при наличии нерепрезентативной выборки скважин ошибка моделирования и множитель Лагранжа прямо пропорциональны весовым коэффициентам данных, недостающих для репрезентативности выборки. На основании этого факта было выдвинуто предположение о том, что множитель Лагранжа может быть использован в качестве меры репрезентативности используемой выборки. Это предположение было проверено на материалах Конторовичского месторождения Томской области, в рамках которого методом двойного Крайгинга последовательно осуществлялось моделирование с участием трех, пяти и семи скважин. При увеличении выборки от трех до семи скважин наблюдалось снижение величины множителя Лагранжа, что подтвердило правильность предположения.

Актуальность. Изменения геополитики и конъюнктуры мировых энергетических рынков всё больше и больше оказывают влияние на мировую экономику, вынуждая не только совершенствовать энергетические технологии, но и определять приоритеты государства в области энергетической политики. Такими приоритетами являются увеличение генерации от новых видов возобновляемых источников энергии и быстрое развитие соответствующих технологий, которые, в свою очередь, обеспечивают удешевление производств. Вместе с этим известно, что повысить надежность энергосистемы и одновременно увеличить производство электроэнергии можно за счет распределённой энергетики, основой которой является, в том числе, и микрогенерация от солнечных электростанций. В этой связи необходимы дополнительные исследования по адаптации существующих методик расчета фотоэлектрических систем к их использованию при разработке и построении маломощных солнечных электростанций. Актуальность обусловлена еще и тем, что необходимо создать максимально эффективную и недорогую систему преобразования солнечной энергии в электрическую, которая бы соответствовала любым заданным техническим требованиям, была надежной и простой в эксплуатации. Цель: разработать эффективную фотоэлектрическую систему и создать недорогую микромощную солнечную электростанцию с заранее заданными параметрами и техническими характеристиками для дальнейших экспериментальных исследований. Методы. При выполнении расчетов и исследовании основных режимов работы и элементов конструкции фотоэлектрических систем использовались результаты многочисленных научных исследований, в том числе и прикладных, и имеющийся на сегодняшний день опыт в области солнечной энергетики, который был получен при выполнении некоторых теоретических и экспериментальных работ. При разработке и моделировании электронных схем использовались многофункциональные системы DipTrace и EasyEDA. Результаты. Обоснована целесообразность применения более простых методик определения вероятной или фактической инсоляции с использованием программного обеспечения PVsyst, и погрешностью расчетов за один год не более 10 %. Разработаны: 1) технология для экспериментального производства фотоэлектрических модулей заданных геометрических размеров и номинальной мощности; 2) надежная за счет актуаторов система управления двухосным солнечным трекером, повышающая эффективность фотоэлектрических систем в широтах Западной и Юго-Западной Сибири; 3) структурная схема управления микромощной солнечной электростанцией; 4) электронные схемы солнечного контроллера MPPT, преобразователя DC-DC, инвертора DC-AC и главного управляющего блока на основе микроконтроллера ATmega326.

Актуальность исследования обуславливается перспективностью вовлечения возобновляемой биомассы (в частности, торфа) в использование для выработки тепловой и электрической энергии. Это позволит частично решить проблему ресурсодефицитных регионов, зависящих от поставок топлива с разрабатываемых угольных месторождений. Цель: исследование теплотехнических характеристик и минеральной части торфа ряда крупных месторождений Томской области для оценки возможности их энергетического использования. Объект. Рассмотрены пробы низинного торфа с месторождений Суховское и Аркадьевское, а также с одного из месторождений Томского района. Методы. Теплотехнические характеристики исследуемых проб были определены согласно ГОСТ Р 55661-2013, 33503-2015, 55660-2013. Значения теплоты сгорания установлены при помощи калориметра АБК-1 (РЭТ, Россия), элементный состав – на анализаторе Vario Micro Cube (Elementar, Германия). Исследование состава минеральной части торфа проводили методом генофлуоресцентного анализа с использованием спектрометра EDX-720-P (Shimadzu, Япония), а также методом рентгеновской дифрактометрии с использованием дифрактометра Shimadzu XRD7000 (CuKα-излучения) со счетчиком монохроматора Shimadzu CM-3121. Характерные температуры плавкости золы определяли согласно ГОСТ 2057-94. Структуру рассматриваемых проб исследовали методом сканирующей микроскопии на электронном микроскопе TM 3000 (Hitaсhi, Япония). Результаты. На основе полученных результатов можно заключить, что использование околотомского торфа для сжигания камерным способом нецелесообразно из-за высокого выхода золы. Однако этот ресурс может быть рассмотрен как минеральное удобрение в сельском хозяйстве благодаря наличию таких элементов, как фосфор, калий. Высокое содержание карбонатов указывает на возможность использования околотомского торфа в качестве добавки к высокосернистым углям для снижения выбросов оксида серы SOх. Характеристики суховского и аркадьевского торфа позволяют рассматривать их в качестве альтернативы привозному топливу. Преимуществами для энергетического использования является малое содержание серы, следствием которого будут минимальные вредные выбросы при сжигании. Более того, наличие большого количества карбонатов может способствовать полному связыванию SOх при сжигании торфа. Предпочтительным способом энергетического использования торфа с месторождений Томской области является его сжигание в кипящем слое.

The teenage transition period is a period of change in behavior that is felt differently. Teenagers have conditions and energy that are very prime and have the potential and reality of fighting spirit and high power of patriotism. In this transition period, adolescents must be conditioned in a positive direction so that adolescents grow into mature adults who behave noble. The transitional period of adolescents is prone to delinquency, both those with the potential for criminal acts and ordinary crime. In many cases events that occur many parents who complain, even troubled, because their children who had stepped on the early teens became stubborn, difficult to manage, young huffed and daydreaming. In the context of the behavior of students at school, the ability of the teacher to carry out his role well, forming the personal of the students so that they grow well, very necessary in the learning process that is right for these students. The role of the teacher must be in the form of guidance services for those who experience difficulties in the transition stage, which in its development is one of the special handling. This means that students who are classified as having problems at the top level need to be prioritized. The reason for choosing the right approach by the teacher is that the transition difficultiesexperienced by the child can be handled optimally and the teacher recognizes the true disturbances.

For this reason, efforts to overcome adolescent behavior during this transition period can be carried out preventive, curative and refresive efforts. Through the approach to Islamic education carried out with a general effort namely Islamic education during the womb, after birth given love and environmental education in the family and in the community. Special efforts are carried out with supervision, guidance and counseling as well as specific actions that are justified by the applicable legislation

Changes and developments in education are identical to learning. Because learning is a means to change. Changes as learning outcomes can emerge changes in physical, intellectual, emotional and behavioral changes. Not all learning can achieve the above, systematic and systematic learning that can lead to these changes. The failure of learning is one of the obstacles to change. Deep understanding of the inhibiting factors of learning is one way to overcome them. Failure to learn is a trigger for academic failure achieved by students at school.

In this paper there are seven factors that lead to academic failure of students in school, among others: The active cycles experienced by students before they become the trigger for further failure, weaknesses in students in learning that are unclear what orientation and learning objectives in school, weak business those who have not yet shown a resilient effort in learning, low self-control that appears in the effort of low self-discipline in learning, lack of noble attitude that does not seem to like the heavy burden of learning, does not like challenges such as lethargy when added with assignments more learning assignments, low perceptions of learning success which usually do not have an effort to pursue higher achievement, hopes of going forward are very low.

All these factors must be packaged systematically so as not to become the biggest obstacle for students in learning not to fail in school. Basically, in schools and in madrasas the teacher has implemented an effort to reduce the failure. It's just that the way teachers do is very conventional, not yet giving contributive meaning to solving student learning failures. like giving assignments or recitation. During this time the task is interpreted in a way to overcome the weaknesses of students, the task should be interpreted as a functional positive attribution to the strengthening of the results of weaknesses or failures of student learning.

Published: February 2019

AbstractAwur Bay waters is an area that has different water conditions, namely closed and open waters. Open water is an aquatic area facing the open sea without any barrier, island and the mainland either in front or in the form of open sea, so that open water is strongly influenced by waves and tides. Consequently in these waters, the waves interaction ,stream will cause turbulence. While the closed waters is impeded by inland waters or in the form of the bay therefore stream and wave power will reduce when it arrived at the beach. Macrobenthic animals are aquatic organisms that live in the bottom sediments, whether on top or in the bottom of sediments. Population is a group of individuals and the same species in a place and time, while indicating the presence of species diversity in ecosystems. The aims of the study is to analyze the difference effects of closed and open waters in the Awur bay Jepara, on the population and diversity of macrobenthic animals based on differences in the characteristics of the waters.
