«Шуховский пролет» листопрокатного цеха Нижне-Выксунского завода
Authors: Mamin Alexander , Kodysh Emil , Bobrov Vladimir , Reutsu Alexander
Published: July 2019

Рассматриваются проблемы сохранения объекта культур­ного наследия «Листопрокатный цех Нижне-Выксунского завода» (АО «ВМЗ»), выполненного по проекту выдающегося русского учёного и инженера В.Г. Шухова, его перемещения в центральную часть города Выксы и дальнейшей реставрации. В статье приведена история создания и эксплуатации листо­прокатного цеха, материалы ранее проведённых обследова­ний, результаты комплексного научного исследованияи 2018 года, включающего натурное обследование, при выполнении которого были зафиксированы многочисленные дефекты и повреждения металлических конструкций, наиболее опасные из которых - щелевая коррозия в узлах сопряжений элемен­тов, глубокая язвенной коррозия элементов арок и фахвер­ковых стоек в приопорной зоне, а также сквозная коррозия элементов покрытия. Представлены результаты проверочных расчётов, которые показали, что прочность и устойчивость цеха («Шуховского пролёта») даже с учётом удаления из расчётной схемы сильно повреждённых узлов и участков эле­ментов конструкций здания цеха, достаточна для восприятия действующих на момент обследования нагрузок, а количество повреждённых конструкций листопрокатного цеха, требую­щих восстановления или замены, будет незначительным и не повлияет на культурно-историческую ценность здания. Для восприятия дополнительных усилий от снеговой нагрузки (в случае, если бы кровельное покрытие в настоящее время было сохранено) потребовалось бы заменить большую часть элементов каркаса цеха либо установить дополнительные опоры, что недопустимо при реставрации объекта культурного наследия. В статье приведены рекомендации по разборке, реставрации элементов перемещаемого в центральную часть города Выксы сооружения методом лазерной наплавки и последующей их сборке, которые позволят сохранить этот уникальный памятник архитектуры и инженерной мысли.
Два источника, две составляющие архитектурных практик Казани (вторая половина XIX начало XX века)
Authors: Nugmanova Gulchachak
Published: July 2019

Статья представляет собой обобщённый взгляд на архитек­турные процессы в Казани во второй половине XIX  начале XX века. Казань, присоединённая к Русскому государству в 1552 году в результате покорения Казанского ханства, воспринималась им­перской властью как центр завоёванного татарского государства и одновременно (по выражению Роберта Джераси) как «окно» России на Восток. Такой взгляд на бывшую «столицу большого царства» предопределил место города в структуре Российской империи, его особую цивилизаторскую миссию, связанную с продвижением «западной цивилизации» на «непросвещённый Восток». В XIX веке столица Казанской губернии стала центром учебного, военного и судебного округов. Проживавшие в городе татарымусульмане являлись частью имперского просветитель­ского проекта. В статье показано, что оба начала  имперское и татаромусульманское  явственно обнаружили себя в облике Казани, но в разном качестве. Первое сказалось в устойчиво­сти классицизма, как правило, связывавшейся с «задержкой» этого стиля в провинции. В случае Казани эта приверженность классической традиции диктовалась скорее актуальностью идеи империи в завоёванном регионе и сохранявшейся потребностью визуализировать её архитектурноградостроительными сред­ствами. Второе отражало общие для эпохи явления, связанные с самоидентификацией народов и нациестроительством, неизбежно охватившие не только титульный русский народ, но и инород­ческое население Российской империи. Их проявлением стали впервые появившиеся общественные здания для татар и интерес к ориентальным формам, иллюстрирующий поиск архитектурного языка для демонстрации татарской национальной идентичности.
О новой энергетической идеологии в пространственном развитии территорий: инновационное совершенствование отраслей ТЭК в урбоэкологическом территориальном развитии
Authors: Sarnatsky Eduard
Published: July 2019

Инновационное совершенствование отраслей ТЭК в урбо- экологическом территориальном развитии рассматривается специалистами в области энергетики как новая энергетиче­ская идеология. Основами развития принимается синтез трёх «Э»: экономика, экология, энергетика как факторов здоровья планеты Земля.

Энергетика - мотор экономики, развития и безопасности общества и государства: состояние и развитие промышлен­ности, АПК, внешнеторговой политики, защиты природы (здесь некая амбивалентность). Эпоха углеводородов предоставляет открытые возможности для развития новых технологий. Как бы не менялись или не трансформировались взгляды и суждения о дальнем и недальнем нашем «завтра», максима «мир будет электрическим, экологическим и цифровым» уже наступает.

При этом постулат «Энергетика = физика + экономика» опре­деляет направленность и сущность энергетической политики в территориальном планировании.

В материале статьи проводится сквозной анализ: от первичных энергоресурсов (их наличия и конечности потребления) до увяз­ки схем тепло- и электроснабжения (нужно исходить из нашей российской климатической особенности - нам нужно две-три единицы тепла на единицу электроэнергии) и газо- и водоснаб­жения плюс энергосбережение - всё это вместе даёт колоссаль­ные эффекты развития - от избавления от излишней мощности стареющих источников до создания новых и реконструкции целесообразных (стоимостные преимущества), до использова­ния в ряде случаев вторичных, возобновляемых энергоресурсов и распределённых источников. Рассмотрен вариант создания Глобального энергетического объединения (ГЭО).

Совершенно необходимо возрождение отраслевой науки и энергомашиностроения; цифровизация, «смарт грид», энергосбережение.
Древние города России, их статус и проблемы сохранения архитектурного наследия
Authors: Naschokina Maria
Published: July 2019

Древние города - это важнейшие свидетельства истории и территориальной целостности России, значимые для её самоидентификации. Статья посвящена проблемам опреде­ления, статуса древних городов нашей страны и сохранения их архитектурного наследия. Автор ставит вопрос о том, что называть древними городами, все ли они сейчас защищены законом как исторические города? Большинство исследова­телей считают таковыми домонгольские города, основанные примерно, начиная с IX века до 1230 годов, то есть до начала монгольских вторжений. Среди них сегодня есть малонасе­лённые и утратившие городской статус посёлки, состоящие из архитектурных или археологических памятников - Изборск, Старая Рязань, Старый Льгов, Ростиславль-Рязанский, Пронск, Херсонес, Булгар и т.д., и города развивающиеся, среди которых явно выделяются крупные города - Ярославль, Рязань, Брянск, Великий Новгород и Псков, большинство же

города малые.

В современных условиях России для многих из них самой важной задачей является сохранение населения, дающего надежду на будущее развитие. Нужно очень многое сделать для коренной переоценки исконных национальных ценностей

мировоззрения, образа жизни и быта, чтобы привычная штур­мовщина и революционные ломки сменились на бережные и здравые эволюционные подходы. В статье рассматриваются вопросы функциональной ориентации городов и занятий их жителей в историческом аспекте. Выдвигаются конкретные предложения о возможной функциональной переориентации городов, о путях решения современных социальных и градо­строительных проблем, которые позволят занять жителей исто­рических городов, а следовательно, не потерять возможность сохранения их архитектурного наследия. Необходимо осознать, что сбережение древних и более молодых исторических горо­дов России - общенародная задача, важное основание само­уважения нации и едва ли не самое наглядное свидетельство её права на занимаемую территорию.
О том, что фактически должно лежать в основе установления границ объектов культурного наследия в виде Достопримечательных мест. Часть 2
Authors: Shevchenko Eleonora , Lukashev Andrej
Published: July 2019

Споры вокруг такого вида объекта культурного наследия, как «Достопримечательные места» не прекращаются с момента принятия в 2002 году Федерального закона № 73-ФЗ «Об объектах культурного наследия (памятниках истории и культуры) народов Российской Федерации», которым был введён в оборот этот новый вид объекта культурного наследия. Главная проблема заключается в недопонимании глубокого смысла, сущности, значимости для сохранения исторической среды населённых мест как фактического генома города - этого уникального Объекта культурного наследия.

Целью данной статьи является раскрытие глубинной сути одного из видов объекта культурно наследия, нередко идентифицируемого с такой категорией «Объектов» наследия, как историческое поселение и нередко приравниваемого к такому виду объекта культурного наследия, как «Памятник». Раскрытие важности определения его в качестве целостного объекта недвижимого имущества, сложнейшего по составу и структурности, вызвано необходимостью принятия срочных мер по сохранению аутентичности, уникальности населённых мест и территорий, вовлекаемых в процесс стратегического развития России.

Доказывается межведомственный характер Достопримечательных Мест, что определяет междисципланарные особенности определения границ данных объектов, являющихся одновременно и границами его территории. Рассматриваются все перечисленные в законе разновидности Достопримечательных Мест.
Морской фасад как часть городского центра Санкт-Петербурга XXI века - неиспользованный потенциал
Authors: Lavrov Leonid , Eremeeva Aleksandra , Perov Fedor
Published: July 2019

Рассматриваются итоги первого этапа реализации страте­гического проекта по формированию нового морского фасада Санкт-Петербурга XXI века на намывных землях у западной око­нечности Васильевского острова. Подчёркивается уникальный потенциал этой территории, её беспрецедентное значение для градостроительного развития города и, особенно, центральной зоны. Новый район, который должен был отражать образ со­временной «Северной столицы», по качеству архитектурных решений не отличается от городской периферии. Перечисляются основания для негативной оценки достигнутых к настоящему времени результатов: недостаточность контактов застройки с акваторией, вытеснение общественно-деловой функции в пользу массовой многоэтажной застройки стандартного об­разца, отсутствие предложений по формированию «знаковых» построек-символов. Прослеживается эволюция проекта под усиливающимся влиянием экономических факторов, его кор­ректировка в соответствии с текущими запросами квартирного рынка. Отмечается, что стратегическое значение имеет инерция городского проектно-строительного комплекса, который с на­чала 1960-х годов специализируется на возведении стандар­тизированных комплексов массового экономичного жилья в периферийных зонах и не подготовлен к учёту специфических условий прибрежной зоны в центральном районе. Показаны выявившиеся дефекты петербургского городского планиро­вания: в проекте «Морской фасад» не рассмотрены в качестве решающих факторов воздействие магистрали западного ско­ростного диаметра (ЗСД) на реконструкцию Васильевского острова и сила его негативного воздействия на экологическую ситуацию. Подчёркивается, что намечаемый перенос сроков завершения проекта и пересмотр взглядов на судьбу северного участка намыва открывают возможность внесения радикальных корректив и стимулируют расширение общегородского центра Санкт-Петербурга в сторону акватории Финского залива.

Determination of dopamine receptor D2 gene rs1800497 polymorphism using real-time polymerase chain reaction
Authors: Baculov Katarina , Vucinic Natasa , Stojcevic-Maletic Jelena , Barjaktarovic Iva
Published: July 2019

Introduction. After analyzing a specific nucleotide sequence, located near
the dopamine receptor D2 gene, rs1800497 polymorphism was detected, that
affects dopamine D2 receptor expression, its density and affinity. This
polymorphism is associated with many disorders such as: aggressive behavior,
response to stress, sensation seeking, impulsivity, extraversion, anger,
random memory, impaired cognitive function, brain glucose metabolism,
obesity, pathologic gambling, substance addiction, depression,
schizophrenia, that are related to modified gene expression, receptor
density and affinity. Due to this association, a considerable interest in
detecting a reliable dopamine receptor D2 gene allele was developed. The aim
of this paper is optimization of real-time polymerase chain reaction in
genotyping dopamine receptor D2 gene rs1800497 polymorphism. Material and
Methods. Deoxyribonucleic acid was extracted from the blood of ten healthy
individuals. Deoxyribonucleic acid samples were genotyped for dopamine
receptor D2 gene rs1800497 (context sequence part containing targeted single
nucleotide polymorphism
CACAGCCATCCTCAAAGTGCTGGTC[A/G]AG?GCAGGCGCCCAGCTGGACGTCCA) by polymerase
chain reaction. The TaqMan assays were used to determine single-nucleotide
polymorphisms. The products of amplification were analyzed using Applied
Biosystems 7500 fast real-time polymerase chain reaction instrument.
Results. After a successful polymerase chain reaction, two alleles that
differed in one nucleotide were detected in our samples. Conclusion. Even
though it is financially more demanding, real-time polymerase chain reaction
method is recommended for dopamine receptor D2 gene genotyping in routine
diagnostics because it is simple, accurate, and fast.
Hydroxyapatite/iron oxide nanocomposite prepared by high energy ball milling
Authors: Vucinic-Vasic Milica , Antic Bratislav , Boskovic Marko , Antic Aleksandar , Blanusa Jovan
Published: July 2019

Nanocomposites (HAp/iron oxide), made of hydroxyapatite (HAp) and
ferrimagnetic iron oxide, were synthesized by high-energy ball milling a
mixture consisting of iron oxide nanoparticles and the starting materials
used for the HAp synthesis: calcium hydrogen phosphate anhydrous (CaHPO4),
and calcium hydroxide (Ca(OH)2). Two HAp/iron oxide samples with the
magnetic phase content of 12 and 30 wt.% were prepared and their
microstructure, morphology and magnetic properties were analysed by X-ray
diffraction and transmission electron microscopy. Furthermore, the
measurement of particle size distribution was performed by laser scattering,
and temperature/field dependence on magnetization was determined. X-ray
diffraction data confirmed the formation of two-phased samples (HAp and
spinel iron oxide) without the presence of any other parasite phase. The
shape of particles was nearly spherical in both samples, ranging from only a
few to several tens of nanometres in diameter. These particles formed
agglomerates with the most common value of the number-based particle size
distribution of 380 and 310 nm for the sample with 12 and 30wt.% of iron
oxide, respectively. Magnetization data showed that both HAp/iron oxide
composites had superparamagnetic behaviour at room temperature.
The influence of alumino-silicate matrix composition on surface hydrophobic properties
Authors: Kljajevic Ljiljana , Melichova Zuzana , Kisic Danilo , Nenadovic Milos , Todorovic Bratislav , Pavlovic Vladimir , Nenadovic Snezana
Published: July 2019

The purpose of this investigation is to investigate the hydrophobicity of
geopolymers, new alumino-silicate materials and the influence of Si/Al ratio
on their surface properties. Contact angle measurement (CAM) as reliable
indicator of hydrophobicity was determined for synthesized geopolymers using
water and ethylene-glycol as reference liquids. Geopolymers were synthesized
from various precursors: kaolin, bentonite and diatomite. Characterization
of phase structure and microstructure was performed by XRD, FTIR, SEM/EDX
methods. Contact angle measurements confirmed that the geopolymers
synthesized from metakaolin are the most porous, which can be explained by
the smallest Si/Al ratio. The maximum value of contact angle and free
surface energy (110.2 mJ/m2) has been achieved for geopolymer synthesized by
diatoms (GPMD). SEM micrograph of GPMD shows a homogeneous surface with some
longitudinal cavities in the gel and is significantly different from the
micrographs of other two geopolymer samples, GPMB and GPMK.
Evaluation of Kalalani vermiculite for production of high strength porcelain insulators
Authors: Ngayakamo Blasius , Park Eugene
Published: July 2019

The present work has evaluated Kalalani vermiculite as a potential raw
material for the production of high strength porcelain insulators. Three
porcelain compositions were prepared to contain 0, 20 and 30 wt% of Kalalani
vermiculite. Porcelain samples were fabricated using a semi-drying method.
The chemical, mineralogical phases and microstructural characterization of
the raw materials were carried out using XRF, XRD, and SEM techniques,
respectively. Water absorption, bulk density, dielectric and bending
strengths were performed on porcelain samples fired up to 1300?C. However,
at the sintering temperature of 1250?C, the porcelain sample with 20 wt% of
Kalalani vermiculite gave the dielectric strength of 61.3 kV/mm, bending
strength of 30.54 MPa, bulk density of 2.21 g/cm3 and low water absorption
value of 0.21 % which is the prerequisite properties for high strength
porcelain insulators. It was therefore concluded that Kalalani vermiculite
has the potential to be used for the production of high strength porcelain
insulators

been analysed using ICP-OES, F?IR and XRD-spectroscopy and chemical
analysis. The results show that hydraulic lime mortar was used with crushed
bricks as artificial puzzolanic aggregate. Large contribution of silicon-
and aluminum-oxides, indicate the presence of quartz and phyllosilicate
minerals derived from the aggregate, river sand and crushed bricks. Also,
high content of Pb and Cu was observed in investigated samples.

OBJECTIVE

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are suspected endocrine disruptors widely detected across populations. We examine the extent to which PFASs are associated with diabetes incidence and microvascular disease. Secondarily, we tested whether a lifestyle intervention modifies associations and decreases concentrations.

RESEARCH DESIGN AND METHODS

We analyzed data from a prospective cohort of 957 participants from the Diabetes Prevention Program (DPP) trial and Diabetes Prevention Program Outcomes Study (DPPOS). At baseline, participants were randomized to an intensive lifestyle intervention of diet, physical activity, and behavior modification or a placebo medication. We quantified plasma concentrations of six PFASs at baseline and 2 years after randomization. Participants were monitored for ∼15 years, repeatedly tested for diabetes, and evaluated for microvascular disease at the end of the follow-up.

RESULTS

A doubling in baseline branched perfluorooctanoic acid concentration was associated with a 14% increase in diabetes risk for the placebo (hazard ratio [HR] 1.14, 95% CI 1.04, 1.25) but not in the lifestyle intervention group (HR 1.01, 95% CI 0.92, 1.11, Pinteraction = 0.11). Mean change in plasma baseline branched perfluorooctanoic acid concentration was greater for the placebo (0.96 ng/mL; 95% CI 0.71, 1.22) compared with the lifestyle intervention group (0.31 ng/mL; 95% CI 0.14, 0.48) 2 years after randomization. Each doubling in N-ethyl-perfluorooctane sulfonamido acetic acid was associated with 17% greater odds of prevalent microvascular disease (OR 1.17, 95% CI 1.05, 1.31), and a similar association was observed for perfluorodimethylhexane sulfonic acid (OR 1.18, 95% CI 1.04, 1.35), regardless of treatment.

CONCLUSIONS

Some plasma PFASs were associated with diabetes and microvascular disease. Our results suggest that exercise and diet may attenuate the diabetogenic association of PFASs.

Parenting of gender equality in early childhood is nurturing through gender education in the family that is undertaken to develop the abilities covering the cognitive, affective and psychomotor aspects of the children. The main thing is to build a children’s sensitivity during the interaction with their social environment. Based on the research findings, the construction of community in Sokaraja believed that the children were a valuable asset to be cared for with love and affection. This required the role and responsibility of parents to provide education to their children; as evidence of children who were as the pride and grace provided by God. Unfortunately, during the education process, there was gender bias happened to children to become unequal in terms of the responsibility and the roles between boy and girl. Gender bias made the children sensitive to the differences and responsibilities. The children were treated in different ways, thus it could generate the feelings of injustice to the children. The construction of understanding within the family eventually influenced the society at large, partly in the school environment. In fact, religious elites often contributed to this gender bias. Therefore, in line with the deconstruction toward the understanding of gender bias, the children needed to be raised in a family environment that had parenting of gender equality so that the children could have sensitivity and responsibility to themselves and his environment. The children’s behavior in the future would depend on the treatment and parenting in the family.

La Descripción geográfico-moral del arzobispo Cortés y Larraz (1770) y la historia léxica de Centroamérica: algunos datos salvadoreños
Authors: Ramírez Luengo José Luis
Published: July 2019

El presente trabajo se entiende como un intento de terminar en parte con la escasez actual de estudios acerca de la historia léxica del español centroamericano; con este propósito, se pretende llevar a cabo el análisis de los americanismos que se pueden descubrir en los capítulos que el arzobispo de Guatemala, el aragonés Pedro Cortés y Larraz, dedica a El Salvador en su Descripción geográfico-moral de la diócesis de Goathemala, redactada en 1770 tras una visita pastoral a su extensísima diócesis.De este modo, y después de facilitar una rápida visión general del vocabulario de la obra, se pasará a analizar aquellas unidades que se pueden considerar americanismos desde una perspectiva de uso y dinámica de este concepto (Company 2010; Ramírez Luengo 2015); en concreto, se tendrán en cuenta cuestiones como los subtipos de americanismos que se descubren y los campos semánticos en que se incorporan, y se prestará una especial atención al uso de los indigenismos como ejemplo del contacto con los pueblos autóctonos, todo ello con la intención final de detectar la presencia de elementos diatópicamente marcados y, por tanto, de subrayar el proceso de dialectalización de este nivel lingüístico que se puede descubrir ya en el español de la región en las postrimerías del siglo XVIII.
