Indications of enhanced soil ecosystem functions in polyculture reforested grassland
Authors: Baldos Angelica , Rallos Roland
Published: June 2019

A lot of work has been doneto evaluate the effects of biodiversity on ecological functions in polyculture plantings. But attention is rarely given to soil ecosystem functions such as carbon (C) sequestration and nitrogen (N) cycling even though they play a critical role in climate regulation through the sequestration and release of greenhouse gases (GHGs). In this study, stable isotopes of C and N were used to investigate if the aforementioned soil ecosystem functions are enhanced under polyculture reforestation by determining the sources of C stored in soil, its rate of incorporation, and the degree of soil N cycling. Twenty-five years after its establishment on an Imperata cylindrica grassland, the tree plantation has contributed 54% of the measured soil organic carbon (SOC) stock at an estimated rate of 2.41Mg C ha-1 yr-1. Larger mean soil 15N values and a more negative 15N enrichment factor (ε = -5.82‰) for the whole 50cm soil depth in tree plantation indicated a better N cycling compared to grassland vegetation. Results show the potential of polyculture reforestation as a sustainable approach to restoring degraded lands and enhancing the role of soil in climate regulation by improving the capacity of soil to store C and to supply N. In addition, information generated from studies like this allow the refinement of mechanisms used in payments for ecosystem services to add more value and provide higher incentives from the ecosystem services provided by polyculture reforestation.

Published: June 2019

In this study, investigation of convective heat transfer enhancement with the use of CuO–Polyaniline (CuO–PANI) nanocomposite basednanofluid inside vertical helically coiled tube heat exchanger was carried out experimentally. In these experiments, the effects of different parameters such as Reynolds number and volume % of CuO–PANI nanocomposite in nanofluid on the heat transfer coefficient of base fluid have been studied. In order to study the effect of CuO–PANI nanocomposite based nanofluid on heat transfer, CuO nanoparticles loaded in PANI were synthesized in the presence of ultrasound assisted environment at different loading concentration of CuO nanoparticles (1, 3 and 5 wt.%). Then the nanofluids were prepared at different concentrations of CuO–PANI nanocomposite using water as a base fluid. The 1 wt.% CuO–PANI nanocomposite was selected for the heat transfer study for nanofluid concentration in the range of 0.05 to 0.3 volume % and Reynolds number range of was 1080 to 2160 (±5). Around 37 % enhancement in the heat transfer coefficient was observed for 0.2 volume % of 1 wt.% CuO–PANI nanocomposite in the base fluid. In addition, significant enhancement in the heat transfer coefficient was observed with an increase in the Reynolds number and percentage loading of CuO nanoparticle in Polyaniline (PANI).
论采煤生产中瓦斯爆炸的原因及预防措施
Authors: 康 宇
Published: May 2019

瓦斯是一种易燃易爆气体，在煤矿井下经常会大量的出现，对于采矿生产有着严重的安全威胁，如果发生瓦斯事故，特别是瓦斯爆炸，带来的影响将是非常严重的，不只是产生大量的经济损失，可能还会造成人员伤亡。所以，瓦斯治理是采煤安全管理的重中之重，而采煤工作面又是瓦斯出现比较多的位置，因此这里的瓦斯治理也成为煤矿瓦斯之理的重点位置。瓦斯爆炸需要满足三个条件，一是瓦斯的浓度、二是出现火源、三就是氧气的浓度，如果这三个条件都达到了就会发生瓦斯爆炸。在采煤过程中，煤壁会向外涌出瓦斯、采落的煤炭也会散发出瓦斯，而采空区也可能会涌出瓦斯，这些瓦斯气体一般都会积聚在上隅角等位置。下面，我们就对之前提到的这些问题进行了详细的分析，在了解了问题产生的原因之后又给出了一些防范的措施，希望能够减少事故的发生。

Authors: Çatak Bilge Deniz
Published: May 2019

Filistin tarihinde yaşanan 1948 ve 1967 savaşları, binlerce Filistinlinin başka ülkelere göç etmesine neden olmuştur. Günümüzde, dünya genelinde yaşayan Filistinli mülteci sayısının beş milyonu aştığı tahmin edilmektedir. Ülkelerine geri dönemeyen Filistinlilerin mültecilik deneyimleri uzun bir geçmişe sahiptir ve köklerinden koparılma duygusu ile iç içe geçmiştir. Mersin’de bulunan Filistinlilerin zorunlu olarak çıktıkları göç yollarında yaşadıklarının ve mülteci olarak günlük hayatta karşılaştıkları zorlukların Filistinli kimlikleri üzerindeki etkisi sözlü tarih yöntemi ile incelenmiştir. Farklı kuşaklardan sekiz Filistinli mülteci ile yapılan görüşmelerde, dünyanın farklı bölgelerinde mülteci olarak yaşama deneyiminin, Filistinlilerin ulusal bağlılıklarına zarar vermediği görülmüştür. Filistin, mültecilerin yaşamlarında gelenekler, değerler ve duygusal bağlar ile devam etmektedir. Mültecilerin Filistin’den ayrılırken yanlarına aldıkları anahtar, tapu ve toprak gibi nesnelerin saklanıyor olması, Filistin’e olan bağlılığın devam ettiğinin işaretlerinden biridir.ABSTRACT IN ENGLISHPalestinian refugees’ lives in MersinIn the history of Palestine, 1948 and 1967 wars have caused fleeing of thousands of Palestinians to other countries.

‘Diyaspora’nın diyasporası
Authors: Brubaker Rogers
Published: May 2019

Son on yıldır ‘diyaspora’ teriminin kullanımının artmasıyla birlikte anlamı da çeşitlilik kazanmıştır. Bu makale, diyasporanın anlamsal, kavramsal ve disipliner alandaki yerini araştırmakta; diyasporanın temeli olarak anlaşılmaya devam eden üç ana unsuru analiz etmekte;  diyaspora kuramcılarının bakış açısında köklü bir kayma ve toplumsal dünyada temel bir değişim olduğuna dair iddialarını değerlendirmekte ve diyasporanın sınırları belli bir olgu olarak değil, bir tabir, durum ve sav olarak ele alınmasını önermektedir. ABSTRACT IN ENGLISHAs the use of ‘diaspora’ has proliferated in the last decade, its meaning has been stretched in various directions. This article traces the dispersion of the term in semantic, conceptual and disciplinary space; analyses three core elements that continue to be understood as constitutive of diaspora; assesses claims made by theorists of diaspora about a radical shift in perspective and a fundamental change in the social world; and proposes to treat diaspora not as a bounded entity but as an idiom, stance and claim.
Alevi Diasporası ve resmi din olarak Alevilikte çoklu kimlik
Authors: Arslan Zeynep
Published: May 2019

Mevcut çalışma, Anadolu Alevilerinin önemli ölçüde dışarıdan gelen tanımlamalara maruz kalmalarına ve Türkiye siyaset konjonktüründe daima “Şeriat tehlikesini” dengeleme amaçlı araçsallaştırılmalarını ele alıyor. Aleviliğin Türkiye toplumunda büyük toplum kesimlerince egemen olan ve devlet erkanında kurumsal olarak işlerliğini sürdüren Sünni-Ortodoks İslam ile kıyaslanma üzerinden tanımlanması durumu, Avrupa Diasporası’nda ve Aleviliğin Avrupa devletleri tarafından tanınma süreçlerinde etkinliğini sürdürmektedir. Özellikle Avusturya örneğinde 2008/2009 yıllarından itibaren Alevi kurumlarınca başlayan Aleviliğin resmi din olarak tanınma (Almanca: Anerkennung als Religionsgesellschaft) çabaları, devlet çıkarları doğrultusunda (1912 İslam yasasını reform etme amaçlı) yeniden araçsallaştırılabileceğine tanık olundu. Bu çalışma, Avusturya’da Alevi kurumlarının tanınma süreçlerinde izledikleri yolu ve sonuç iti-bariyle Avusturya-Alevi toplumunun kurumsal olarak iki kanada bölünme sürecinin nedenlerini incelemektedir. Konunun içeriğini güncel siyasi ve hukuki süreci belgeleyen kaynaklar ile kritik söylem çözümlemesi yöntemiyle devletin kimlik belirleme hususu, hakimiyet ve egemenlik çerçevesinde iç ve dış etkenlerin karşılıklı ilişkilendirmeleriyle, kimliklerin kategorize edilerek oluşumu konusunu ‘kesişimsellik’ (İngilizce: Intersectional approach) teorik altyapısıyla destekleyeceğim.ABSTRACT IN ENGLISHAlevi diaspora and multiple identities in Alevism as an ‘officially recognised religion’This paper focuses on the Anatolian Alevis, whose identity is often defined externally by others and they face political manipulation as a leverage group against fundamentalist Islamic tendencies. The way in which Alevism is commonly defined in contrast to Sunni-Orthodox Islam, an institutional and hegemonic faith in Turkey continues with Alevi Diaspora in Europe[1]too. In particular, in the case of Austria (German: Anerkennung als Religionsgesellschaft), where the recognition of Alevism as a religion dates back to 2008/2009 and it shows how the state manipulates the Alevi population’s goals for her own purposes (Amendment of the 1912 Islam Law). This study focuses on the way in which Alevi faith group is divided into two at the end of this process of regcognition in Austria. These groups are the Islam Alevis and the (Syncretic) Alevis. This paper analyses the roles of the Austrian Alevi associations and the Austrian state in this process of division and official recognition. The analyses are based on content analysis of documents on current political and judicial decisions and benefits from critical discourse analysis approach. The intersectional theoretical approach is tested when the dominance and hegemony aspects, mutual influences of internal and external factors as well as identity buildings through categorization are analysed.

Published: May 2019

1979 yılında işgal ve devamındaki terör yüzünden ülkelerinden koparak göçer duruma düşmüş ve Hatay-Ovakent’e yerleştirilmiş Özbek asıllı bir grup Afganistan vatandaşının kültür ve kimliklerini koruma çabalarını, kültürel değişimlerinin yönü ve hızını, değişimlerinin düzey ve biçimlerini belirlemeye yönelik yapılan ve sahada gerçekleştirilen anket çalışmasıyla desteklenen bu çalışma, kültürel azınlık bir topluluk durumundaki göçerlerin kültür(süz)leşme (acculturation) sürecini incelemektedir. Çalışmada, kültürel boyutlarıyla ele alınan topluluğun durumu makro düzeyde değerlendirilmiştir. Yedi bin kişilik göçer nüfusun 0.03 oranında küçültülmesiyle, farklı yaş ve cinsiyetten, 210 kişilik denek grubuna kültürün devamlılığı, çeşitliliği, değişimi ve egemen kültürle bütünleşme sürecini ölçmeye yönelik, yaşam biçimleri, benimsedikleri kimlik, dinsel uygulamaları, örf ve adetleri, aidiyetleri, meslekleri ve yemek kültürlerine yönelik yirmi dört soruluk bir sormaca uygulanmıştır. Yanıtlar Likert ölçekleme yöntemi ve John W. Berry’nin göçerlerin başka kültürlerle temasları durumunda karşılaştıkları süreçleri ele aldığı kültür(süz)leşme izlemleri kuramı çerçevesinde değerlendirilmiştir. Elde edilen veriler, Özbek göçerlerin Türk toplumuyla her yönüyle bütünleşmeyi sürdürdüğü, ancak Ovakent’in egemen kültür bireylerinden ayrık bir konumda olmasının bu süreci yavaşlattığını göstermektedir..ABSTRACT IN ENGLISHAcculturation among Uzbek Immigrants in OvakentThis study, based on a survey, explores the efforts and experiences of maintaining the culture and identity among Uzbek immigrants, who were uprooted due to the occupation and the terror in 1979, and had moved to Hatay-Ovakent. It examines the process of acculturation of Uzbek migrants in a community in order to understand the process and speed of a cultural change. In this study, the Uzbek community is analysed at macro level. A questionnaire of twenty-four questions about the continuity of culture, diversity, exchange and integration processes are explored with a sample representing 0.03 percent of (210 respondents) a migrant community of seven thousand. The responses were collected using a questionnaire employing Likert Scale questions following the framework of acculturation strategies theory of John W. Berry regarding immigrants in contact with other cultures. We have found that Uzbek migrants continue to acculturate with Turkish society in all aspects, but due to Ovakent’s isolated position and distance from the mainstream culture in Turkey, this process has seemingly slowed down.

Savaşın başladığı 2011 yılından itibaren milyonlarca Suriyeli çeşitli rotaları takip ederek önce komşu ülkelere daha sonra da Avrupa içlerine doğru hareket etmiştir. Türkiye’de Gaziantep ve İzmir, Macaristan’da ise Szeged Suriyelilerin Batı Avrupa’ya doğru uzanan göç rotasının değişik noktalarında yer almaktadır. Bu çalışmanın amacı Suriyelilerin Kuzey Suriye - Batı Avrupa göç rotasının giriş, transit ve çıkış noktalarında yer alan bu üç şehirdeki Suriyelilerin ve buralarda yaşayan yerel halkın güvenlik algılarını ortaya koymaktır. Bu amaca yönelik olarak analiz, yorumcu (interpretivist) bir perspektiften yapılacaktır. Çalışma Gaziantep’te 2011-2015, İzmir’de 2015-2017 ve Szeged’de 2015-2017 yılları arasında yapılan gözlemlere, yapılandırılmamış veya yarı yapılandırılmış görüşmelere dayanmaktadır. Böylece Suriyeli mültecilerin ve yerel halkın güvenlik algıları insani güvenliği kavramsal çerçevesinde karşılaştırılmıştır. Yapılan karşılaştırma sonucunda üç kentte de Suriyelilerin ve yerel halkın güvenlik algılarının, o şehrin göç rotasının hangi noktasında bulunduğu, uluslararası mülteci rejimi ve ulusal düzeydeki mülteci politikalarından etkilenmiş olduğu ortaya çıkmıştır.ABSTRACT IN ENGLISHHuman Security Perceptions of Syrians and the Local People in Border Provinces of Gaziantep, Izmir and SzegedSince the beginning of the war in 2011, millions of Syrians have left their country by following the various routes to move into neighbouring countries first, then into Europe. Gaziantep and Izmir in Turkey and Szeged in Hungary are situated at the different points of Syrian migration route from Northern Syria to Western Europe. This study aims to explore the security perceptions of Syrians and the local people living in these cities. For this purpose, an interpretivist approach was taken. The study is based on observations, unstructured and semi-structured interviews that were conducted in Gaziantep İzmir and Szeged between 2011 and 2017. Security perceptions of Syrian refugees and local people were compared within the context of human security perspective. The study found that the security perceptions of Syrians and the local population in three cities were affected by the position of these cities at the migration route, international refugee regime and refugee policies at the national level.
The Impact of International Remittances on Poverty Alleviation in Bangladesh
Authors: Kumar Bezon
Published: May 2019

This article mainly explores to what extent international remittances alleviate household poverty in Bangladesh. This study uses primary data collected from 216 households and employs multi-methods. Firstly, I measure the level of household poverty through Foster-Greer-Thorbecke index. The article secondly focuses on the impact of remittances on household poverty using a binary logistic regression model. I found that the level of poverty among remittance recipient households is notably lower than households that are not receiving remittances. Similarly, the probability of a household being poor is alleviated by 28.07 per cent if the household receives remittance. It can be suggested that nursing international remittances can be useful for poverty alleviation in Bangladesh.

O treinamento de força conta com diversos benefí­cios para a saúde, trazendo adaptações positivas no sistema cardiovascular. Desta maneira, o objetivo deste estudo se pautou em identificar as respostas agudas da pressão arterial em exercí­cios básicos do treinamento de força. O estudo foi realizado com 8 praticantes de treinamento de força do sexo masculino (21,4 ± 1,68 anos), com no mí­nimo 1 ano de treinamento ininterrupto, normotensos, nos exercí­cios agachamento livre e supino reto, sendo executados testes de 1 RM para determinação da intensidade. Os avaliados foram submetidos a dois testes, com intervalo de no mí­nimo 48 horas entre eles. No primeiro, foram executadas 3 séries do exercí­cio supino reto a 100% de 1 RM e no segundo, 3 séries a 100% de 1 RM do exercí­cio agachamento livre. Uma semana depois realizaram o mesmo procedimento com 80% de 1 RM. A pressão arterial foi aferida antes e imediatamente após a execução de cada série. Houve uma diferença estatisticamente significativa considerando as alterações na pressão arterial sistólica (PAS) nos valores de 100% de 1 RM e 80% de 1 RM quando comparamos o valor de PAS de repouso no exercí­cio de agachamento livre e as respostas agudas na 1ª, 2ª e 3ª séries. Quanto í  pressão arterial diastólica (PAD), não observa-se nenhuma diferença significativa nos valores de 100% e 80% de 1 RM entre a PAD de repouso no exercí­cio agachamento livre e as respostas agudas na 1ª, 2ª e 3ª séries. Tais resultados nos remetem ao quão seguro e benéfico pode ser um treinamento realizado em intensidades mais elevadas e o estudo esclarece o funcionamento da pressão arterial quando o corpo é submetido a altas cargas, sendo possí­vel uma prescrição de protocolos seguros e adequados dentro das academias.Palavras-chave: musculação, adaptação fisiológica, pressão arterial.

Diversas diretrizes defendem que para uma vida saudável é importante a prática de exercí­cios fí­sico de forma regular, de forma a estimular promoção de saúde, prevenção e tratamento de doenças crônicas, o que reflete em melhor qualidade de vida. Sendo assim, o treinamento fí­sico torna-se uma ferramenta de interesse da saúde pública. Entretanto, a falta de tempo e as limitações fí­sicas muitas vezes são utilizadas como barreira no engajamento de uma vida menos sedentária. Nestas circunstâncias, o método de treinamento intervalado no ambiente aquático sugere ser uma ferramenta eficaz no combate ao sedentarismo, uma vez que requer menos tempo e utiliza de um meio possí­vel para prática de exercí­cios fí­sicos por aqueles com limitações, crônicas ou temporárias, nas articulações ou músculos, bem como para treinos recreacionais ou até mesmo por opção mais atrativa para alguns. Portanto, o objetivo deste estudo foi elucidar os benefí­cios do treinamento intervalado de alta intensidade no ambiente aquático através de uma revisão de literatura que explorou o treinamento intervalado de alta intensidade e sua possí­vel relação com o ambiente aquático. O método de treinamento proposto se mostrou eficiente, seguro e adaptável, proporcionando benefí­cios e melhorias da saúde para diferentes públicos. Os estudos mostram melhorias no condicionamento fí­sico abrangendo tanto adaptações centrais, como periféricas. Assim, sabendo-se que ambiente aquático é um meio possí­vel na busca da qualidade de vida, mais pesquisas nessa área faz-se necessárias para esclarecer melhor o método, as adaptações necessárias no meio, e os benefí­cios para diferentes públicos.

Published: June 2019

Nude mice are the usual animal model for studying orthotopically implanted human tumors, and ultrasound imaging has emerged as a viable method for measuring tumors implanted orthotopically. The aim of this study was to evaluate ultrasound findings of liver tumors implanted into mice using a 13-MHz transducer and to correlate these findings with gross pathology and histological examinations. Tumor samples from liver metastases were obtained surgically from patients, and 1-mm³ fragments were implanted into the liver parenchyma of 38 nude mice. Mice were imaged monthly by ultrasound until sacrifice. Of the 38 mice implanted with tumor fragments, 11 developed tumors. Ultrasound detected nodular lesions in the 11 macroscopically positive animals and was able to identify the features of the engrafted tumors. Ultrasound imaging is a viable and noninvasive method for evaluating the liver parenchyma of nude mice, and showed 100% sensitivity and specificity in detecting and characterizing lesions.
Identidade de gênero e orientação sexual: a sexualidade no contexto escolar

Published: May 2019

O presente texto tem o objetivo de discutir a diversidade de gêneros e orientações sexuais, que compõem o contexto escolar sob a ótica docente. Diante de tais fenômenos realizou-se uma pesquisa com 12 professores do ensino médio de uma escola pública da cidade de Cuiabá-MT. Na pesquisa de cunho qualitativo, foram investigados os sentidos atribuídos por esses docentes ao fenômeno da sexualidade e suas manifestações no contexto de sua práxis. Para análise dos fragmentos de relatos apreendidos mediante entrevista semiestruturada, adotou-se, enquanto olhar teórico-metodológico, o Construcionismo Social por meio da análise de repertórios linguísticos e investigou-se a produção de sentidos enunciados por práticas discursivas.  A sexualidade, ainda que tratada como um fenômeno ‘natural’ a todo ser humano, apresenta-se em sua complexidade e diversidade como um constructo social, assim como as variadas formas de identidades. Aparecem, então, discursos voltados à ausência de informações a respeito de tais fenômenos, o que impossibilita em grande medida que a transversalidade proposta pelos Parâmetros Curriculares Nacionais (PCNs) seja de fato realizada por esses educadores. A escola ainda se mostra frágil e carente de formação para lidar com temas envoltos na sexualidade, seja no diálogo acerca dos gêneros, orientações ou mesmo diversidade sexual. Tal realidade observada precisa ser transformada através de currículos, normas, e metodologias que considerem as diversidades de gênero, culturas, etnias, classes, e demais subjetividades humanas, presentes no ambiente educacional. Neste movimento, a transversalidade de temas como a sexualidade se farão possíveis, bem como a efetiva construção de novos conhecimentos e saberes.

Metodologicamente, a pesquisa pode ser classificada como exploratória, a abordagem segue um enfoque qualitativo. O instrumento de coleta de dados consisitiu em um questionário estruturado com 18 perguntas abertas, aplicado com os diretores das escolas pesquisadas. A partir dos resultados foi possível concluir que, apesar da realidade de restrição hídrica e da constante falta de água no cotidiano escolar, ainda não há um gerenciamento focado no uso eficiente e sustentável da água nestas escolas, onde nota-se a ausência de feedback das secretarias de finanças e educação para com gestores escolares, no intuito de propiciar um melhor controle de consumo de água dos prédios escolares, bem como a falta de instalações que possuam mais eficiência, e de um trabalho mais aprofundado junto aos alunos, que propicie maior consciência acerca da importância do uso consciente e sustentável da água.

Historicamente, a educação profissional no Brasil fundamenta-se em políticas voltadas para a classe dos menos favorecidos. Essa é uma realidade que marca uma dualidade persistente de separação entre a educação básica e a educação profissional. Assim, a história da dualidade estrutural na educação brasileira está relacionada com a história da luta de classes no capitalismo. Diante dessa realidade, objetivou-se, com o presente estudo, analisar historicamente os dilemas da educação profissional no Brasil, contextualizando com as leis que regem essa modalidade de educação no país. Para isso, referenciou-se em alguns instrumentos legais acerca da educação profissional no Brasil, e em estudos de pesquisadores como Saviani, Frigotto, Machado e Kuenzer, por se tratarem de estudiosos que são referência na área temática de educação e trabalho. Esta pesquisa é qualitativa, com caráter exploratório, do tipo bibliográfica e documental. Os resultados apontam que os dispositivos legais relacionados à educação profissional no Brasil articulam-se, essencialmente, aos interesses do capital; e, apesar dos avanços alcançados na última década, com a criação da Rede Federal de Educação Profissional, Científica e Tecnológica, e dos Institutos Federais de Educação, Ciência e Tecnologia, faz-se necessário que a sociedade brasileira exija de seus governantes medidas que permitam a educação profissional cumprir sua missão social de educar de acordo com o contexto sociopolítico, cultural, científico e tecnológico.

Published: May 2019

This study aims at investigating gender differences in written texts using Halliday’s framework about the functions of language. Halliday claimed that females’ writing style is, what he described as, ‘involved’ while males’ writing style is more ‘informative’. The results of the study do not confirm Halliday’s assumptions about gender differences in writing. No significant differences were found between males and females in the frequencies of the use of nouns, prepositions, numerals and modifiers. The only significant difference that was found is the use of pronouns, which is not enough to account for the assumptions. This paper also aims to investigate the differences between Arabic and English in the average sentence length, lexical density, and readability. To measure readability, the Gunning-Fog index formula was used. The results show that there was no significant difference between Arabic and English in the average sentence length, but there were significant differences in lexical density and readability.

Published: June 2019

Ni-doped VO2(B) samples (NixVO2(B)) were fabricated by a facile one-step hydrothermal method. When evaluated as a cathode material for lithium ion batteries (LIBs), these Ni-doped VO2(B) exhibited improved lithium storage performance as compared to the pure VO2(B). In particular, when the doping amount is 3%, NixVO2(B) showed the highest lithium storage capacity, best cycling stability, smallest electrochemical reaction resistance, and largest lithium diffusion coefficient. For example, after 100 cycles at a current density of 32.4 mA/g, NixVO2(B) delivered a high specific discharge capacity of 163.0 mAh/g, much higher than that of the pure VO2(B) sample (95.5 mAh/g). Therefore, Ni doping is an effective strategy for enhancing the lithium storage performance of VO2(B).
Information-Domain Analysis of Cardiovascular Complexity: Night and Day Modulations of Entropy and the Effects of Hypertension

Published: May 2019

Multiscale entropy (MSE) provides information-domain measures of the systems’ complexity. The increasing interest in MSE of the cardiovascular system lies in the possibility of detecting interactions with other regulatory systems, as higher neural networks. However, most of the MSE studies considered the heart-rate (HR) series only and a limited number of scales: actually, an integrated approach investigating HR and blood-pressure (BP) entropies and cross-entropy over the range of scales of traditional spectral analyses is missing. Therefore, we aim to highlight influences of higher brain centers and of the autonomic control on multiscale entropy and cross-entropy of HR and BP over a broad range of scales, by comparing different behavioral states over 24 h and by evaluating the influence of hypertension, which reduces the autonomic control of BP. From 24-h BP recordings in eight normotensive and eight hypertensive participants, we selected subperiods during daytime activities and nighttime sleep. In each subperiod, we derived a series of 16,384 consecutive beats for systolic BP (SBP), diastolic BP (DBP), and pulse interval (PI). We applied a modified MSE method to obtain robust estimates up to time scales of 334 s, covering the traditional frequency bands of spectral analysis, for three embedding dimensions and compared groups (rank-sum test) and conditions (signed-rank test) at each scale. Results demonstrated night-and-day differences at scales associable with modulations in vagal activity, in respiratory mechanics, and in local vascular regulation, and reduced SBP-PI cross-entropy in hypertension, possibly representing a loss of complexity due to an impaired baroreflex sensitivity.

A successful utilization of deep geothermal resources requires accurate predictions about the distribution of reservoir temperature as well as of the hydraulic processes exerting a direct influence on the productivity of geothermal reservoirs. The aim of this study was to investigate and quantify the influence that regional thermo-hydraulic processes have on the geothermal configuration of potential reservoirs in the German Federal State of Hesse. Specifically, we have addressed the question of how the regional thermal and hydraulic configuration influence the local hydro-thermal reservoir conditions. Therefore, a 3D structural model of Hesse was used as a basis for purely hydraulic, purely thermal and coupled 3D thermo-hydraulic simulations of the deep fluid flow and heat transport. As a result of our numerical simulations, Hesse can be differentiated into sub-areas differing in terms of the dominating heat transport process. In a final attempt to quantify the robustness and reliability of the modelling results, the modelling outcomes were analyzed by comparing them to available subsurface temperature, hydraulic and hydrochemical data.
Drivers of Electricity Poverty in Spanish Dwellings: A Quantile Regression Approach
Authors: de Arce Rafael , Mahía Ramón
Published: May 2019

The main objective of this article is to explore the causes of household electricity poverty in Spain from an innovative perspective. Based on evidence of energy inequality across households with different income levels, a quantile regression approach was used to better capture the heterogeneity of determinants of energy poverty across different levels of electricity expenditure. The results illustrate some interesting and counter-intuitive findings about the relationship between household income and electricity poverty, and the technical efficiency of quantile regression compared to the imprecise results of a standard single coefficient/OLS approach.

Published: June 2019

The increasing share of renewable energies in the electricity sector promotes a more decentralized energy supply and the introduction of new flexibility options. These flexibility options provide degrees of freedom that should be used optimally. Therefore, in this paper, a model predictive control-based multi-objective optimizing energy management concept for a hybrid energy storage system, consisting of a photovoltaics (PV) plant, a battery, and a combined heat pump/heat storage device is presented. The concept’s objectives are minimal operation costs and reducing the power exchanged with the electrical grid while ensuring user comfort. In order to prove the concept to be viable and its objectives being fulfilled, investigations based on simulations of one year of operation have been carried out. Comparisons to a simple rule-based strategy and the same model predictive control scheme with ideal forecasts prove the concept’s viability while showing improvement potential in the treatment of nonlinear system behavior, caused by nonlinear battery losses, and of forecast uncertainties.

Quercetin is an abundant flavonoid in nature and is used in several dietary supplements. Although quercetin is extensively metabolized by human enzymes and the colonic microflora, we have only few data regarding the pharmacokinetic interactions of its metabolites. Therefore, we investigated the interaction of human and microbial metabolites of quercetin with the xanthine oxidase enzyme. Inhibitory effects of five conjugates and 23 microbial metabolites were examined with 6-mercaptopurine and xanthine substrates (both at 5 μM), employing allopurinol as a positive control. Quercetin-3′-sulfate, isorhamnetin, tamarixetin, and pyrogallol proved to be strong inhibitors of xanthine oxidase. Sulfate and methyl conjugates were similarly strong inhibitors of both 6-mercaptopurine and xanthine oxidations (IC50 = 0.2–0.7 μM); however, pyrogallol inhibited xanthine oxidation (IC50 = 1.8 μM) with higher potency vs. 6-MP oxidation (IC50 = 10.1 μM). Sulfate and methyl conjugates were approximately ten-fold stronger inhibitors (IC50 = 0.2–0.6 μM) of 6-mercaptopurine oxidation than allopurinol (IC50 = 7.0 μM), and induced more potent inhibition compared to quercetin (IC50 = 1.4 μM). These observations highlight that some quercetin metabolites can exert similar or even a stronger inhibitory effect on xanthine oxidase than the parent compound, which may lead to the development of quercetin–drug interactions (e.g., with 6-mercaptopurin or azathioprine).

Coagulation factor XIII (FXIII) is a plasma-circulating heterotetrameric pro-transglutaminase complex that is composed of two catalytic FXIII-A and two protective/regulatory FXIII-B subunits. FXIII acts by forming covalent cross-links within a preformed fibrin clots to prevent its premature fibrinolysis. The FXIII-A subunit is known to have pleiotropic roles outside coagulation, but the FXIII-B subunit is a relatively unexplored entity, both structurally as well as functionally. Its discovered roles so far are limited to that of the carrier/regulatory protein of its partner FXIII-A subunit. In the present study, we have explored the co-presence of protein excipients in commercial FXIII plasma concentrate FibrogamminP by combination of protein purification and mass spectrometry-based verification. Complement factor H was one of the co-excipients observed in this analysis. This was followed by performing pull down assays from plasma in order to detect the putative novel interacting partners for the FXIII-B subunit. Complement system proteins, like complement C3 and complement C1q, were amongst the proteins that were pulled down. The only protein that was observed in both experimental set ups was alpha-2-macroglobulin, which might therefore be a putative interacting partner of the FXIII/FXIII-B subunit. Future functional investigations will be needed to understand the physiological significance of this association.
