İnşaat Sektörünün Dayanıklılığını Konut Sunumunun Ötesinde Aramak
Authors: AKSOY KHURAMİ Esma
Published: December 2019

Türkiye’de, özellikle 2000’li yıllardan itibaren inşaat sektörü ekonomiyi canlandırmak ve ev sahipliğini arttırmak amacıyla kamu politikalarıyla doğrudan desteklenmiştir. Bu amaca ulaşmak için kentler benzeri görülmemiş inşaat sahalarına dönüşmüş, imara yeni açılan alanlar aracılığıyla yeni konut üretimi gerçekleştirilirken, eskiyen kent dokuları yıkım ve yeniden yapım süreçlerine tanık olmuşlardır. Ekonomik büyüme inşaat sektörü eksenli olunca sonsuza kadar devam eder anlayışı güdülmüş, kamu ve özel sektör yatırımlarında inşaat yatırımları büyük paylar almaya başlamıştır. 2007 ve 2009 yılları arasında etkisini hissettiren Küresel Finansal Krizle beraber pek çok ülke inşaata dayalı ekonomik büyümeye mesafeli yaklaşmaya başlamış ve sektörün olası olumsuz etkilerini azaltmak için çeşitli tedbirler almıştır. Ancak Türkiye’deki genel eğilim bu yönde olmamakla beraber özellikle imara açılan yeni alanlar ve kentsel dönüşüm alanlarında inşaat faaliyetlerinin devam ettirilmesi sağlanmıştır. İnşaatın öncü olduğu bir büyüme modelinde sektörü kırılma noktasına getirebilecek tehlikeli sinyaller görmezden gelinmiştir. Bu çalışmada temelde, sektörün güçlü yönü kabul edilen sözde dayanıklılığını kırması olası değişkenleri saptamayı hedeflemektedir. Çalışmada 2005-2018 yılları arasında üretilen Türkiye İstatistik Kurumu (TÜİK) İnşaat Sektörü Eğilim İstatistikleri, İnşaat ve Konut İstatistikleri, Türkiye Odalar ve Borsalar Birliği (TOBB) Kurulan ve Kapatılan Şirket İstatistikleri, T.C. Merkez Bankası Konut ve İnşaat İstatistikleri kullanılacaktır.

Published: December 2019

Dünya üzerinde insan faaliyetleri ve enerji tüketiminin giderek artmasıyla önemli oranda artış gösteren sera gazları sonucunda küresel iklim değişikliği yaşanmakta ve iklim değişikliğinin küresel sıcaklık artışı, iklimlerde kaymalar, buzulların erimesi, okyanus ve deniz seviyelerinin yükselmesi gibi etkilerinin somut olarak gösterildiği çalışmalar da artmaktadır.İklim değişikliğinin etkisi ile artan sıcaklıklar sonucu kış turizmi merkezlerinin dayandığı temel doğal kaynak olan doğal kar miktarı, kar kalınlığı ve su kaynakları azalma meydana gelmektedir. Güvenlik sıcaklıklarının artması ve kıs yağışlarının azalması kış turizmi faaliyetlerini de olumsuz etkilemektedir.  Türkiye İklim Değişikliği Birinci Ulusal Bildirimine göre 2100 yılına kadar kış sıcaklıklarında 2.5–3°C’ye varan artışlar ve kar kalınlıklarında 20 cm’ye varan incelmeler öngörülmektedir. Kıs yağışlarının azalması, kar sezonunun kısalması ve kar kalınlıklarının da azalması ile kış turizmini ve insan sağlığını tehdit eden durumların ortaya çıkması kaçınılmaz görülmektedir.Türkiye için önemli bir ekonomik sektör konumunda olan turizmin çeşitlenmesi ve 12 aya yayılması stratejisi kapsamında birçok kayak merkezine önemli yatırımlar yapılmakta ve kış turizmini geliştirmeye yönelik çalışmalar devam etmektedir. Ancak kış turizmi merkezleri iklim değişikliğinin etkilerinden ciddi anlamda etkilenecek alanlar olduğundan bu konuda yeterli bilgilendirme ve önlemlere ilişkin çalışmaların yapılmasına ihtiyaç vardır.Çalışmanın amacı iklim değişikliği etkilerine karşı kırılganlığı yüksek olan kış turizminin bu değişimlerden nasıl etkileneceğinin ortaya konulması, Türkiye’de seçilen kış turizmi merkezlerinin iklim değişikliğinden etkilenme durumu ve uyum kapasitesi ile dayanıklılığının değerlendirilmesinde hangi ölçütlerin kullanıldığına yönelik bir örnek uygulama ortaya koymaktır. Bu amaçla Türkiye’nin önemli kış turizm merkezlerinden 1850-2200m. yükseklik kuşağında yer alan Bolu Köroğlu Dağı (Kartalkaya) Kış Turizmi Merkezi ile 2200-3176 m. yükseklik kuşağı üzerinde yer alan Erzurum Palandöken Kış Turizmi Merkezi olmak üzere iki kış turizm merkezinin iklim değişikliğine karşı dayanıklılığının seçilen göstergeler ve bunların ağırlıklandırılması yoluyla değerlendirilmesi sağlanmıştır.Yapılan dirençlilik analizi sonucunda yükseklik, coğrafi konum, mikroklimatik özellikler turizm çekicilikleri ulaşım vb. değerlendirildiğinde Erzurum Palandöken Kış Turizmi Merkezinin, dirençliliğinin daha yüksek olduğu bulunmuştur. Sonuçta turizm politikası ve turizm merkezi planlamasında alınacak kararlara altlık oluşturulması hedeflenmekte ve planlama çalışmaları yapılırken iklim değişikliği etkilerinin de dikkate alınması gerektiğine dikkat çekilmektedir.
Antroposen Çağı’nda Kentsellik, Sürdürülebilirlik ve Dirençlilik
Authors: POLAT Erkan , KAHRAMAN Sümeyye
Published: December 2019

Artık değişen bir
dünyada, kentsel ölçekli sürdürülebilirlik ve dirençlilik kavramlarını toplu
olarak yeniden gözden geçirme zamanı geldi de geçiyor bile. Politik
tartışmalarda sürdürülebilirliğin sürdürülmesi, aşırı karmaşıklık, radikal
belirsizlikler ve benzeri görülmemiş bir değişim/dönüşüm ile karakterize edilen
bir dünya yaratan Antroposen gerçeği görmezden gelme noktasının çok ötesine
geçmiş durumda. Böyle bir dünyada sadece “sürdürülebilirlik ve dirençlilik”
hedefi olarak bile olsa, bu kavramları tanımlamanın bile mümkün olmadığı
gerçeği ile yüzleşmemiz şart görünüyor.Farklı uzmanlık
kürelerinde, farklı yorum ve tanımlara sahip iki soyut ve karmaşık kavram olan
dirençlilik ve sürdürülebilir gelişme/kalkınma kavramları bir araya geldiğinde
yeterince karmaşıkken, kapsama alanına kentsellik ve insanın
baskınlığı/egemenliği anlamında Antroposen Çağı girdiğinde daha da kaotik bir
durum ortaya çıkmaktadır. Antroposen, yalnızca antropojenik bir değişim dönemi
değildir, dünyamız ve yaşadığımız gezegen hakkında yeniden düşünmemiz
gerektiğini anlatan bir kavramdır ve gelişim/dönüşüm için derin etkileri
vardır.Kentsel ve
bölgesel ölçekte, dirençlilik tanımlayıcı bir kavram olarak bir kentsel
sistemin dinamik özellikleri ve uyum sağlama kapasitesi hakkında fikir
verirken, sürdürülebilirlik normatif bir kavram olarak, nesiller arası ve
nesiller-ötesi (trans-generational) adaletin temel fikirlerini ortaya koyar. Bu
çalışmada dirençlilik, kentsellik ve sürdürülebilir gelişme/kalkınma arasındaki
iç içe, yan yana ve üst üste sistemik ilişkilerden hareketle, ekolojik ve
sosyo-ekonomik iki doğal sermaye stoğunun, insan refahını tamamlayan ve artıran
ekosistem hizmetlerinin sunduğu bir kurama dayanarak, ekolojik-sosyo-ekonomik
sistemin ve epistemolojik yapının dinamikleri ve sürdürülebilirlik koşulları
karşılaştırılmaktadır.Sistemin belirli bir durumunda dirençliliğin
sürdürülebilir gelişme ve kalkınma için hem gerekli hem de yeterli olduğunun,
dirençliliğinin yeterli, ancak gerekli olup olmadığının, dirençliliğinin gerekli,
ancak yeterli olup olmadığının ve sistemin dirençliliğinin sürdürülebilir
kalkınma için ne gerekli ne de yeterli olup olmadığının çözümlemelerinin
yapılacağı bu çalışmada, ekolojik-sosyo-ekonomik sistemlerin ve epistemolojik
yapının kentsel sürdürülebilirlik yönetimi için stratejiler ve politikalar
tasarlanırken sistemin mevcut durumunun dirençliliğinden daha fazla kriterin
dikkate alınması gerektiği sonucuna ulaşılmaktadır.
Afet Sonrası Hanehalklarının Yer Seçim Kararları ve Kentsel Dirençlilik: Değirmendere Örneği
Authors: ORHAN Ezgi , KESKİNOK Çağatay
Published: December 2019

Bu çalışma ile, afetlerin hemen sonrasında acil durum koşullarında hanehalklarının afet bölgesinde kalma veya alanı terk etme kararlarının kentsel dirençliliğin inşasında önemli bir unsur olarak görülmektedir. Bu çalışmanın amacı, afete maruz yerleşimlerde yaşayanların afetin hemen sonrasında yer seçim kararlarını ve beklentilerini irdeleyerek kentsel dirençlilik üzerine bir tartışma yürütmektir. Çalışma, 1999 Depremi’nin etkilerinin yoğun olarak görüldüğü Değirmendere kenti örneğinde afeti yaşamış hanehalklarını temel almaktadır. Çalışmada, Orta Doğu Teknik Üniversitesi Şehir ve Bölge Planlama Bölümü 1999-2000 ders yılı 2. sınıf Planlama Stüdyosu’nda yürütülmüş olan Değirmendere Planlama Projesi kapsamında gerçekleştirilmiş hanehalkı anketlerinden yararlanılmıştır. Depremin hemen ardından Ekim 1999 tarihinde çadırkentlerde ve yerleşik konut alanlarında yaşayan toplam 490 hanehalkına uygulanan anket çalışması stüdyo projelerinin bir parçası olarak saha araştırması yoluyla elde edilmiştir. Anketlerde afete maruz kalmış nüfusun genel demografik niteliklerinin yanı sıra hasar düzeyi, alınan yardım türü ve taşınma istekleri sorgulanmış, yanıtların betimsel istatistikleri çıkarılmıştır; ancak çalışmanın yapıldığı dönemin koşulları göz önüne alındığında afetzedelerin anket sorularının tamamını yanıtlayamadığı görülmektedir. Nüfusun yaklaşık % 10’luk büyüklüğüne ulaşan bir örneklemde uygulanan anket çalışmalarında tespit edilen afet bölgesini afetin hemen sonrasının koşullarında bile terk etmeme isteği, alanın yeniden inşası için en önemli itici güç olarak görülmelidir. Çalışma ile, afetin yarattığı psikolojik sarsıntılara karşın, afet sonrasında deprem bölgesinde oluşan “aidiyet duygusunun” güçlülüğü kentsel dirençliliğin inşasına katkı koyacak biçimde politikaları şekillendirebileceği sonucuna ulaşılmıştır.
Russia in world trade: Between globalism and regionalism
Authors: Melchior Arne
Published: December 2019

The article examines Russia’s participation in world trade and trade policy, using trade data for 1996–2017 and simulations of a numerical world trade model where Russia is divided into domestic regions. Since the mid-1990s, Russia’s foreign trade has grown much faster than the world average. This was accompanied by rapid deterioration in the trade balance for manufacturing, and fast redirection of imports, with more from China and relatively less from others, especially Eastern Europe. Only 1/8 of Russia’s foreign trade in 2017 was with Eastern Europe. This is why Russia can gain more from trade integration with the world beyond Eastern Europe, according to the model simulation analysis. For Russian domestic regions, multilateral liberalization among all countries has a similar effect across all of them, with a welfare gain due to lower import prices. For the commodity-exporting regions of Russia, preferential free trade agreements (FTAs) have a similar impact. For the more industrialized Russian regions, on the other hand, FTAs lead to manufacturing growth, rising wages and higher prices, and a larger welfare gain. According to the model simulations, trade integration promotes industrial diversification, with manufacturing growth also in some commodity regions. The results indicate that external liberalization is particularly important for the central parts of Russia; with Volga and West Siberia generally obtaining the strongest manufacturing boost from trade integration.
How does China fare on the Russian market? Implications for the European Union
Authors: Garcia-Herrero Alicia , Xu Jianwei
Published: December 2019

This paper reviews China’s growing economic ties with Russia. We conclude that such ties have strengthened in terms of trade and cross border lending, but less in terms of Chinese foreign direct investment in, or portfolio flows to, Russia. Meanwhile, Europe remains Russia’s largest trading partner, lender and investor. In relation to trade, China seems to have become more of a competitor for the EU on Russia’s market when we appraise China’s increasing export share and the increasing value added of its exports and previous empirical analysis at the product level. Increasing competition between European and Chinese exports should not be surprising as there is ample evidence that China has been moving fast up the technology ladder during the past few decades. Competition over investment and lending is more limited but the situation could change rapidly with China and Russia giving clear signs of a stronger-than-ever strategic partnership.
The EU–Russia–China energy triangle
Authors: Zachmann Georg
Published: December 2019

There is a growing worry in the EU that a rapprochement between Russia and China can have negative implications for the EU. This paper argues that energy relations between the EU and Russia and between China and Russia influence each other. To do this, the paper analyzes interactions in oil and gas trading, electricity exchanges, energy technology exports and energy investments. No evidence for a negative spillover of developing Russia–China energy relations on the EU is found.
The Development of a Manipulative Spectrophotometric Technique for the Determination of Aminexil in a New Hair Tonic Preparation
Authors: Youssif Dina M. , R. Rezk Mamdouh , M. Essam Hebatallah
Published: December 2019

A simple and economic ratio difference spectrophotometric method was developed and validated for the determination of Aminexil (AX), which is a new compound patented by L'Oreal, in the presence of niacinamide (NA) and pyridoxine (PD) in a newly introduced cosmetic preparation. The proposed method was found to be suitable for the determination of Aminexil in its laboratory prepared mixture in presence of the two other components; and in the commercial cosmetic preparation where the three components were co-formulated. The calibration curve was constructed with a concentration range from 2-10 μgmL-1 showing 100.22± 0.53 accuracy. The LOD and LOQ were found to be 0.53 and 1.6 μgmL-1 respectively. The method was validated according to ICH guidelines. The standard addition methods showed satisfactory mean recovery of 99.68±0.56.The obtained results were satisfactory enough for further statistical analysis, in comparison to the reported method. The proposed method had the advantage of being simple since no manipulation or complicated handling of the samples were needed, as well as economic, since there was no use of sophisticated instruments or expensive chemicals.

Determination of Stiffness Characteristics for WWER-1000 Support Components
Authors: Vasylchenko V. , Koliadiuk А. , Posokh V. , Dubkovsky V.
Published: December 2019

Available approaches to computer justification of safe operation of reactor support components (RSC) are generally presented in the reports justifying RSC lifetime extension at Ukrainian NPPs. The experience of performing such calculations and analyzing the results indicates that there are issues to be improved. Thus, in particular, RSC stress-strain state is not analyzed for all force factors in the available calculations. It is typical for the reports on RSC lifetime extension justification that the strength assessment of the RSC is performed in an axisymmetric formulation (1/30). Meanwhile, a complex asymmetrical load from the main circulation pipelines is not considered, which affects RSC stress-strain state calculations as some stiffness characteristics (horizontal and torsional stiffness) cannot be determined correctly in a 1/30 axisymmetric formulation.

The paper proposes a methodology for determining RSC stiffness in a complete formulation (without applying symmetry conditions), taking into account all geometric features and the interaction between individual structures and nodes of RSC. Thus, for each RSC (support ring, thrust ring, separating bellows), based on geometric features and types of connection to other components, stiffness to be determined to calculate the forces is defined (six for support ring and separating bellows and three for thrust ring respectively). Single loads in the form of forces and moments were imposed on the remote points connected to corresponding RSC surfaces to determine stiffness. This load made it possible to obtain the displacements and rotation angles of the corresponding remote points, which were used to calculate the stiffness characteristics.

The described approach was first used in the calculations performed within justification of KhNPP Unit 1.

Construction of the New Safe Confinement (NSC) above the Shelter over destroyed Chornobyl NPP Unit 4 has been completed. The NSC design is based on boundary conditions for current and potential hazardous impacts of the Shelter. Accordingly, criteria for Shelter safe state have to be established, in particular, criteria for the safe state of fuel-containing material (FCM) accumulations.

The paper presents the results of the development of methodological recommendations for the establishment of acceptance/non-acceptance criteria of FCM accumulations with regard to safety, as well as on the FCM monitoring scope in order to monitor the extent of compliance of FCM state with the established criteria.
História dos animais no Brasil: tradições culturais, historiografia e transformação
Authors: Duarte Regina Horta
Published: December 2019

Este ensaio visa apresentar o estado da arte dos estudos sobre animais realizados pelos historiadores no Brasil. Sérgio Buarque de Holanda identificou uma tradição cultural luso-brasileira, na qual predominou uma relação de extrema imprevidência e antropocentrismo em relação ao mundo natural e, consequentemente, aos animais, desde os primeiros anos de colonização do território. Frente ao caráter inovador de algumas obras de Sérgio Buarque no tratamento dos animais, e da reconhecida importância desse historiador, é surpreendente que esse aspecto tenha sido obscurecido pela historiografia brasileira entre os anos 1960 e os 2000. Em anos recentes, os animais têm invadido o horizonte de interesse dos historiadores. Não obstante, ainda não se pode falar num campo de estudos sobre animais realmente bem estabelecido na historiografia brasileira. A conclusão discute as possíveis razões dessa lacuna.
Considerações ético-políticas na História (Ambiental): escalas e o presentismo da devastação
Authors: Arruda Gilmar , Colácios Roger
Published: December 2019

Este artigo tem como tema a possibilidade de discussão dos princípios ético-políticos na História Ambiental. As considerações feitas aqui têm como base a perspectiva de crise do presente e a devastação ambiental. Ambos são vistos a partir da violação dos direitos não humanos, perpetrada por uma guerra travada há décadas contra o mundo natural, dirigida pelos ditames do capitalismo e suas diversas agendas econômicas, políticas e sociais dentro dessa temporalidade. A exemplificação do tema está no processo de ocupação do norte paranaense no século XX e mantida até os dias de hoje, que não apenas alterou a paisagem florestal da região, mas dizimou milhões de espécies de arvores e animais silvestres e talvez bilhões de microrganismos. Espera-se, portanto, promover o debate sobre os caminhos analíticos da História Ambiental e a responsabilidade dos pesquisadores, entre tantas outras, enquanto promotores de conhecimento sobre as relações entre seres humanos e não humanos.

Novel aptamer to von Willebrand factor A1 domain (TAGX-0004) shows total inhibition of thrombus formation superior to ARC1779 and comparable to caplacizumab
Authors: Kazuya Sakai  , Tatsuhiko Someya  , Kaori Harada  , Hideo Yagi  , Taei Matsui  , Masanori Matsumoto
Published: December 2019

von Willebrand factor (VWF) is a blood glycoprotein that plays an important role in platelet thrombus formation through interaction between its A1 domain and platelet glycoprotein Ib. ARC1779, an aptamer to the VWF A1 domain, was evaluated in a clinical trial for acquired thrombotic thrombocytopenic purpura (aTTP). Subsequently, caplacizumab, an anti-VWF A1 domain nanobody, was approved for aTTP in Europe and the United States. We recently developed a novel DNA aptamer, TAGX-0004, to the VWF A1 domain; it contains an artificial base and demonstrates high affinity for VWF. To compare the effects of these three agents on VWF A1, their ability to inhibit ristocetin- or botrocetin-induced platelet aggregation under static conditions was analyzed, and the inhibition of thrombus formation under high shear stress was investigated in a microchip flow chamber system. In both assays, TAGX-0004 showed stronger inhibition than ARC1779, and had comparable inhibitory effects to caplacizumab. The binding sites of TAGX-0004 and ARC1779 were analyzed with surface plasmon resonance performed using alanine scanning mutagenesis of the VWF A1 domain. An electrophoretic mobility shift assay showed that R1395 and R1399 in the A1 domain bound to both aptamers. R1287, K1362, and R1392 contributed to ARC1779 binding, and F1366 was essential for TAGX-0004 binding. Surface plasmon resonance analysis of the binding sites of caplacizumab identified five amino acids in the VWF A1 domain (K1362, R1392, R1395, R1399, and K1406). These results suggested that TAGX-0004 possessed better pharmacological properties than caplacizumab in vitro and might be similarly promising for aTTP treatment.

Published: December 2019

Immune thrombocytopenia is a common bleeding disease caused by autoantibody-mediated accelerated platelet clearance and impaired thrombopoiesis. Accumulating evidence suggests that desialylation affects platelet life span in immune thrombocytopenia. Herein, we report on novel effector functions of autoantibodies from immune thrombocytopenic patients which might interfere with the clinical picture of the disease. Data from our study show that a subgroup of autoantibodies is able to induce cleave of sialic acid residues from the surface of human platelets and megakaryocytes. Moreover, autoantibody-mediated desialylation interferes with the interaction between cells and extracellular matrix proteins leading to impaired platelet adhesion and megakaryocyte differentiation. Using a combination of ex vivo model of thrombopoiesis, a humanized animal model, and a clinical cohort study, we demonstrate that cleavage of sialic acid induces significant impairment in production, survival as well as function of human platelets. These data may indicate that prevention of desialylation should be investigated in the future in clinical studies as a potential therapeutic approach to treat bleeding in immune thrombocytopenia.
Determinants of Microentrepreneurial Success in One of the Small Island Developing States of the Pacific: Evidence from Samoa
Authors: Leofo Romalani , Salele Afualo
Published: December 2019

This study examines the attributes of Samoan microentrepreneurs to identify the important determinants of business success measured by income. Using survey analysis, we find a positive association between participation in social support network, age of microentrepreneurs, and business income. Additionally, we find weakly significant results that participation of microentrepreneurs in microfinance increases their business income. Furthermore, we find that social support network participation has a positive and significant impact on microbusiness income. Our findings extend the results of prior studies, and should be of interest to government authorities, non-government organisations and microfinance institutions for policy planning and future improvements in the microfinance sector. We recommend for microfinance policy makers and practitioners to value the importance of creating safe environments for microentrepreneurs to interact with each other and with various groups from the community for support and growth.

Authors: Singh Gurmeet , Sewak Aarti , Reddy Karuna , Ram Sharan
Published: December 2019

This study seeks to understand variations in Human Immunodeficiency Virus (HIV) risk perception and sexual behaviour among male and female adults in Fiji. The Second-Generation Surveillance Report (2006) indicates the median age of first sex within the youth group as 16 years (range 10 – 23 years). Therefore, this study was purposively targeted at individuals of reproductive age, preferably 10 years and above. We utilized convenience sampling to collect 137 self-administered surveys from individuals working in both public and private sector organizations in two highly populated areas of Fiji. Independent samples t-test analyses revealed that men living in urban areas are more likely to experiment with multiple sexual partners, have a higher tendency of engaging in sexual practices, and are highly likely to have unsafe sex with multiple partners. Gender-sensitive interventions may help facilitate and achieve positive behaviour change among males and influence the sexual health of females.
Explaining Policy Change in Samoa’s Mental Health System
Authors: Fadgen Timothy
Published: December 2019

Modern mental health systems are the products of successive waves of policy development and adaptation. This is particularly so in many low to middle income countries that inherited colonial mental health laws, and institutions often followed by legislative shifts at independence. But how otherwise do these systems change? And why do these systems change? This article applies historical institutionalism to consider policy change over time, in a single case study of a small island state, Samoa. In doing so, the article will consider three discrete policy change episodes to argue that national policy change in the area of mental health has been the result of foreign direction or influence. These three critical change events occurred leading to policy change: colonisation, independence and the intervention of an intergovernmental organisation. These findings are instructive for future, domestically-driven policy change initiatives, in providing the importance of historical policy development and the continuing importance of international policy advocates in promoting policy change.

Authors: ERİŞİR Tülay , KARDAĞ Neslihan Cansu
Published: December 2019

In this paper, we have obtained spinor with two complex components representations of Involute Evolute curves in $\mathbb{E}^3$. Firstly, we have given the spinor equations of Frenet vectors of two curves which are parameterized by arc-length and have arbitrary parameter. Moreover, we have chosen that these curves are Involute Evolute curves and have matched these curves with different spinors. Then, we have investigated the answer of question "How are the relationships between the spinors corresponding to the Involute Evolute curves in $\mathbb{E}^3$?". Finally, we have given an example which crosscheck to theorems throughout this study.

Published: December 2019

INTRODUCTION: The evolution and preservation of venous gas emboli (VGE), as markers of decompression stress, were investigated during alternating high- and moderate altitude exposures, thus, simulating a fighter aircraft high-altitude flight, interrupted by refueling excursions
to lower altitudes.METHODS: Eight men served as subjects during three normoxic simulated altitude exposures: High = 90 min at 24,000 ft; High-Low = three × 30 min at 24,000 ft, interspersed by two 30-min intervals at 15,000 ft; Low = 90 min at 15,000 ft. VGE scores were assessed
by cardiac ultrasound, using a 5-grade scale. Respiratory nitrogen exchange was measured continuously using a modified closed-circuit electronic rebreather.RESULTS: Both High and High-Low induced persistent VGE, with no inter-condition difference either at rest [median (range):
High: 1 (0-3), High-Low: 2 (0-3)] or during unloaded knee-bends [High: 3 (1-4), High-Low: 3 (0-4)], whereas VGE was considerably less in Low, both at rest [0 (0-1)] and during knee-bends [0 (0-2)]. In High-Low, VGE decreased temporarily during the 15,000-ft excursions, but resumed pre-excursion
values upon return to 24,000 ft. During the final descent to ground level, VGE were more persistent following High-Low than High. In both High and Low, nitrogen was continuously washed out at altitude, whereas in High-Low, the washout at 24,000 ft was interrupted by nitrogen uptake at 15,000
ft.DISCUSSION: In normoxic conditions, long-duration flying at a cabin altitude of 24,000 ft is associated with substantial VGE occurrence, which is not abolished by intermittent excursions to a cabin altitude of 15,000 ft.Ånell R, Grönkvist M, Gennser M, Eiken

Published: December 2019

BACKGROUND: Gradual ascent is impractical for personnel deploying to the South Pole due to logistical challenges. Prevention of altitude illness relies on prophylactic medications such as acetazolamide and behavioral modifications including hydration and avoidance of overexertion.
We present three recent cases of altitude illness that occurred in previously healthy individuals at the South Pole.CASE REPORTS: 1) A 52-yr-old woman not on prophylactics presented with headache and intractable vomiting 7 h after arriving and hiking around the station. She was
treated with acetazolamide, dexamethasone, oxygen, and supportive care. Her symptoms resolved during the evacuation flight. 2) A 23-yr-old man presented with dyspnea at rest 3 d after arriving without prophylactic treatments. He had a Sao2 of 49%, wheezes and crackles
on lung exam, and interstitial infiltrates on chest X-ray. His treatment included oxygen, nifedipine, acetazolamide, and dexamethasone. His symptoms resolved during the evacuation flight. 3) A 40-yr-old man presented with dyspnea after a series of strenuous workouts since his arrival 5 d prior.
He had a Sao2 of 41%, and his chest X-ray was consistent with high altitude pulmonary edema. He was treated with oxygen, nifedipine, and fluids before descent to sea level, where his symptoms fully resolved 4 d later.DISCUSSION: These patients illustrate that
altitude illness may develop despite medical screening, participant education, and availability of prophylactic medications based on published guidelines. These cases could be attributed to noncompliance and misinformation, bringing to light some of the challenges with managing more diverse
populations that deploy to remote environments.Rose JS, Law J, Scheuring R, Ramage MH, McKeith JJ. Serious altitude illness at the South Pole. Aerosp Med Hum Perform. 2020; 91(1):46–50.

Published: December 2019

Cobalt oxides and/or manganese and their com-position based on cerium and zirconium oxides (CeO2 : ZrO2 = 1:1 mol.%) with a content of up to 20 wt. % are synthesized. Samples of both individual oxides and complex oxide compositions were prepared by precipitation from solutions of am-monia (room temperature) or hexamethylenetet-ramine (80–90 °C) followed by heat treatment. Results of DTA show, that due to the calcination at 400 ° C (2 h), the obtained samples lose 17–22 wt. % corresponding to 2–3.8 molecules of water. According to the X-ray powder analysis, initially are formed hydroxide compounds of cobalt (CoO· xH2O) and manganese (MnO2·yН2О), which, after being heated at 400 °C for 2 hours, are converted into mixed oxides from the composition of Co3O4 and Mn3O4. The average particle size calculated by the Sherer equation is 18–30 nm.

In the study of catalytic activity on the example of the reaction of the hydrogen peroxide decomposition, it was found that the obtained samples from the solution of GMTA show a greater ability to catalytically decompose hydrogen peroxide compared to samples obtained from the ammonia solution. In this case, the catalytic activity of dried samples is twice as high as roasted, regardless of the method of obtaining. Samples of oxide compo-sitions with deposited 5–10 wt. % of Ce–Zr oxides (1:1) exhibit the highest ability to decompose H2O2. In this case, samples of compositions obtained from the solution of GMTA, have a prolonged catalytic action, and when precipitation in the solution of ammonia, the reaction takes place quite actively during 4–5 days.

Compositions formed from co-deposited or mechanically mixed hydroxocompounds of cobalt and manganese with 5 wt. % of CeO2–ZrO2 (1:1) deposited on them have different catalytic activity. In the case of mechanically mixed, it is 30% lower and with subsequent calcination at 400 °C, it is reduced by almost half, and with co-precipitation, the activity is quite high and does not change with heat treatment. In the case of obtaining samples of Co–Mn with Ce–Zr (1:1) deposited on them in excess of 10 wt. % the catalytic activity of the samples dried at 80 °C is equal to the activity of the co-deposited hydroxocompounds of cobalt and manganese and  the  calcination  at  400  °C  it  reduces  it by  30 %.

The best ability for catalysis was found in samples CoO·xH2O + 5 wt. % MnO2·yН2О, СоO×хН2О + 10 wt. % CeO2:ZrO2 and СоO×хН2О–MnO2×yН2О, precipitated with the GMTA solution and dried at 80 °C. The besser catalytic properties revealed a sample of СоО×хН2О + 10 wt. % CeO2:ZrO2, which with-out stirring is capable of decomposing 1.2–1.4 dm3/g of hydrogen peroxide with a rapid reaction and in the experiment the volume of H2O2 reacted was 3.4 dm3/g.
INTERACTION OF CIS-Pd(NH3)2Cl2 WITH DIPHOSPHONIC ACIDS IN SOLUTIONS AT PHYSIOLOGICAL CHLORIDE-IONS CONCENTRATION
Authors: Kozachkova Oleksandra , Tsaryk Nataliia , Pekhnyo Vasyl
Published: December 2019

The complex formation of cis-Pd(NH3)2Cl2 with 1-hydroxyethylidene-1,1-diphosphonic (HEDP, H4L1), 3-amino-1-hydroxypropylidene-1,1-diphosphonic (AHPrDP, H4L2), and 1-aminopropylidene-1,1-diphosphonic (APrDP, H4L3) acids in aqueous solutions with the concentration CKCl=0.15 mol/L, which corresponds to the concentration of chloride ions in the intercellular fluid, has been studied by spectrophotometry and pH potentiometry. The results of studying the interaction between cis-Pd(NH3)2Cl2 and diphosphonic acids have been interpreted taking into account the equilibrium concentration distribution of complexes forming in Pd(NH3)2Cl2 solutions at a chloride ion concentration of 0.15 mol/L. It has been found that when Pd(NH3)2Cl2 is dissolved in 0.15 mol/L KCl, ammonia molecules are substituted by chloride ions and a water molecule in the pH range of 2 – 4 to form chloro-aqua complexes [PdCl4]2- and [PdCl3(H2O)]-.
In the case of complex formation of Pd(II) chloro-aqua complexes with HEDP and AHPrDP, complexes with [Pd 2OPO3 2Cl] chromophore with bidentate coordination of ligands by two oxygen atoms of phosphonic groups are formed in the acidic pH range. At pH>5, a [Pd(L1)(NH3)2]2- complex (lgβ=30.55(5)) is formed in the cis-Pd(NH3)2Cl2:HEDP=1:1 system, and at pH>6, a [Pd(HL2)(NH3)2]- complex (lgβ=40.29(2)) is formed in the cis-Pd(NH3)2Cl2:AHPrDP=1:1 system. The formation of complexes with [Pd 2OPO3 2Namine] chromophore takes place with the displacement of chloride ions from the coordination sphere of complexes with [Pd 2OPO3 2Cl] chromophore by ammonia molecules.
In the system cis-Pd(NH3)2Cl2:APrDP=1:1, the ligand is coordinated to Pd(II) in a bidentate fashion by the nitrogen atoms of the amine group and oxygen atoms of the phosphonic group to form a [Pd(H2L3)Cl2]2- complex with [Pd Namine OPO3 2Cl] chromophore in the acidic pH range. When pH is increased to 5 and then to 7, a sequential substitution of chloride ions by ammonia molecules takes place to form a [Pd(HL3)(NH3)Cl]2- complex (lgβ=38,84(4)) with [Pd 2Namine OPO3 Cl] chromophore and a [Pd(HL3)(NH3)2]- complex (lgβ=43,14(2)) and [Pd(L3)(NH3)2]2- complex (lgβ=34.91(2)) with [Pd 3Namine OPO3] chromophore.

Implementation of Language Policy in School Education of the Chuvash Republic (late 1980s– 2019)
Authors: Boyko Ivan , Alevtina Dolgova , Kharitonova Valentina G.
Published: December 2019

The article discusses some of the problems of language policy in the Chuvash Republic. Attention is paid to the Chuvash language teaching in educational institutions after the adoption of republican legislation on languages in 1990. This process was not simple, it was accompanied by a lack of understanding of the necessity of studying the Chuvash language in the regions of the republic where Russian population predomiates over the Chuvash one. For more than a quarter of a century, considerable experience has been gained in the organization and methods of teaching the Chuvash language, and despite the fact that it has barely become more widely spoken, it has become more familiar at the domestic and public levels. The transition to the voluntary learning of native languages began in the second half of 2017 and was accompanied by organizational difficulties. The article also gives opinions of the Chuvash language teachers on the problems of its teaching and usage in the family and social environment.
