Telehealth as a Panacea Amidst Global Pandemic (COVID-19) in Africa
Authors: ALHASSAN Gloria Nnadwa , ÖZTÜRK İlknur , ADEDOYİN Festus Fatai , BEKUN Festus Victor
Published: March 2021

Technology is disrupting bringing up a better innovation and strengthening the healthcare services. Telehealth is one of these services. Telehealth can help in times of emergency situations as well as reducing morbidity caused by other diseases other than coronavirus and also constraining its spread as well as sustaining the country's economic development. Although, telehealth is a disruptive innovation, this article aimed to point out why Africa and rest of the world need telehealth to structure out the management of the three phases of health crises (pre, during and post-crises) that must be address to help in economic sustainability, increase accessibility to healthcare and increase in quality of life which in turn reduces costs and easy access to healthcare services either incommunicable, non-communicable, or disastrous situations in the African region. In fighting an outbreak such as this, our study finds that the government of African nations should guarantee all health experts get fitting instruction and preparing; present telehealth accreditation for wellbeing experts; give subsidizing which satisfactorily takes care of the expense of giving telehealth; overhaul clinical models of care; bolster all partners with a viable correspondence; and finally, change the board technique while setting up frameworks to oversee telehealth benefits on a standard premise.

Intraspecific classification of cultivated plants is necessary for the conservation of biological diversity, study of their origin and their phylogeny. The modern cultivated wheat species originated from three wild diploid ancestors as a result of several rounds of genome doubling and are represented by di-, tetra- and hexaploid species. The identification of wheat ploidy level is one of the main stages of their taxonomy. Such classification is possible based on visual analysis of the wheat spike traits. The aim of this study is to investigate the morphological characteristics of spikes for hexa- and tetraploid wheat species based on the method of high-performance phenotyping. Phenotyping of the quantitative characteristics of the spike of 17 wheat species (595 plants, 3348 images), including eight tetraploids (Triticum aethiopicum, T. dicoccoides, T. dicoccum, T. durum, T. militinae, T. polonicum, T. timopheevii, and T. turgidum) and nine hexaploids (T. compactum, T. aestivum, i:ANK-23 (near-isogenic line of T. aestivum cv. Novosibirskaya 67), T. antiquorum, T. spelta (including cv. Rother Sommer Kolben), T. petropavlovskyi, T. yunnanense, T. macha, T. sphaerococcum, and T. vavilovii), was performed. Wheat spike morphology was described on the basis of nine quantitative traits including shape, size and awns area of the spike. The traits were obtained as a result of image analysis using the WERecognizer program. A cluster analysis of plants according to the characteristics of the spike shape and comparison of their distributions in tetraploid and hexaploid species showed a higher variability of traits in hexaploid species compared to tetraploid ones. At the same time, the species themselves form two clusters in the visual characteristics of the spike. One type is predominantly hexaploid species (with the exception of one tetraploid, T. dicoccoides). The other group includes tetraploid ones (with the exception of three hexaploid ones, T. compactum, T. antiquorum, T. sphaerococcum, and i:ANK-23). Thus, it has been shown that the morphological characteristics of spikes for hexaploid and tetraploid wheat species, obtained on the basis of computer analysis of images, include differences, which are further used to develop methods for plant classifications by ploidy level and their species in an automatic mode.

There are more than 30 inherited human disorders connected with repeat expansion (myotonic dystrophy type I, Huntington’s disease, Fragile X syndrome). Fragile X syndrome is the most common reason for inherited intellectual disability in the human population. The ways of the expansion development remain unclear. An important feature of expanded repeats is the ability to form stable alternative DNA secondary structures. There are hypotheses about the nature of repeat instability. It is proposed that these DNA secondary structures can block various stages of DNA metabolism processes, such as replication, repair and recombination and it is considered as the source of repeat instability. However, none of the hypotheses is fully conf irmed or is the only valid one. Here, an experimental system for studying (CGG)n repeat expansion associated with transcription and TCR­-NER is proposed. It is noteworthy that the aberrations of transcription are a poorly studied mechanism of (CGG)n instability. However, the proposed systems take into account the contribution of other processes of DNA metabolism and, therefore, the developed systems are universal and applicable for various studies. Transgenic cell lines carrying a repeat of normal or premutant length under the control of an inducible promoter were established and a method for repeat instability quantif ication was developed. One type of the cell lines contains an exogenous repeat integrated into the genome by the Sleeping Beauty transposon; in another cell line, the vector is maintained as an episome due to the SV40 origin of replication. These experimental systems can serve for f inding the causes of instability and the development of therapeutic agents. In addition, a criterion was developed for the quantif ication of exogenous (CGG)n repeat instability in the transgenic cell lines’ genome.

Problems in the differential diagnosis of abdominal non-organ tumors
Authors: Kolobanova E. S. , Medvedeva B. M.
Published: March 2021

Rationale: The differential diagnosis between lesions requiring surgical intervention and those necessitating medical treatment poses a significant problem for current imaging methods of fat-containing masses in the small intestine mesenterium.Aim: To identify differential diagnostic criteria for various fat-containing neoplasms of abdominal cavity at the preoperative stage.Materials and methods: This retrospective study included data from 29  patients (16  women and 13 men, aged 32 to 81 years, mean age 56 years) with fat-containing masses in the small intestine mesenterium who had undergone preoperative examination at N.N. Blokhin National Medical Research Center of Oncology from 2016 to 2020. Abdominal computed tomography (CT) with intravenous contrast enhancement and assessment of the size, contours, structure and involvement of main vessels was performed in all patients. To interpret single soft tissue nodes within the mass, we used our own list of main CT symptoms (number, size, shape, contours and structure of nodes, degree of their contrast enhancement, and maximal amplification).Results: Fat-containing abdominal masses were morphologically verified as follows: mesenteric panniculitis 13  (45%), well differentiated liposarcoma 10  (35%), lymphoproliferative disorders 4  (14%), lipoma and Castleman disease 1  case each (3%). Twelve (12) of 29  patients (41%) had surgery for various types of tumors, while 17  (59%) patients received appropriate medical treatment after a puncture biopsy-based morphological diagnosis. The CT sensitivity for the detection of fat-containing abdominal neoplasms in our series was 93,1%. The paper describes the radiological signs of the above mentioned mass types with an emphasis on the complexity of their diagnosis.Conclusion: In most cases, CT data can accurately differentiate abdominal liposarcomas from other benign and malignant masses in the small intestine mesenterium.

Drought and its impact on the bio-production of forests
Authors: Kozumplíková Alice , Kalasová Žaneta , Vyskot Ilja
Published: March 2021

The precipitation deficit, heat waves and subsequent drought significantly affected the forests in the Czech Republic. Primarily, forests were affected by physiological insufficiency and later by biotic and abiotic factors. On the initiative of the Ministry of the Environment of the Czech Republic, a study of the condition and damage of forest functions in the model area was formulated. The study was aimed at the model locality of the Bohemian-Moravian Highlands, especially the forest management unit of the Da?ice municipality (South Bohemian Region). The study uses certified national methodologies for evaluating forest function damage (Vyskot et al. 2003; Vyskot et al. 2014). This paper specifies the state and damage of the bio-production function depending on the represented forest management groups, stand types of woody plants and age phases of stands, in terms of value (in %) and finance in Czech koruna (CZK, the currency of the Czech Republic). In particular, spruce stands and their dominant mixtures of non-matured and fully matured trees were affected by major damage of a destructive nature. Due to the changed ecosystem conditions, a modified concept of forest management was proposed.
The Reaction of the Consumption of Fossil Fuels to Trade Openness in Latin America & the Caribbean Countries
Authors: Koengkan Matheus , Fuinhas José Alberto , Vieira Isabel
Published: March 2021

This article investigates the impact of trade openness and renewable energy on the consumption of fossil fuels for a panel of fourteen LAC countries over the period from 1990 to 2014. To this end, a PARDL model in unrestricted error-correction form is estimated, and robustness checks are performed by estimating a PNARDL model. The results of the PARDL model point indicate that the impact of economic growth and elasticity of trade openness are statistically significant at the 1% level and contribute to increased consumption of fossil fuels in the LAC countries. However, the impact and elasticity of consumption of renewable energy are statistically significant at 1% and 5% levels and thus contribute to decreasing consumption of fossil fuels. Nevertheless, the asymmetry of the impact of consumption of renewable energy and its elasticity decrease the consumption of fossil fuels. Therefore, the positive impact of trade openness on the consumption of fossil fuels suggests that the process of globalisation by trade liberalisation in the LAC countries is not sufficient to bring more investment that encourages R&D in energy efficiency technologies, and equipment that reduces the consumption of energy from non-renewable energy sources by households and firms.

Review of research on speech technology
Authors: San-Segundo Rubén , Martínez-Hinarejos Carlos D. , Ortega Alfonso
Published: March 2021

In the last two decades, there has been an important increase in research on speech technology in Spain, mainly due to a higher level of funding from European, Spanish and local institutions and also due to a growing interest in these technologies for developing new services and applications. This paper provides a review of the main areas of speech technology addressed by research groups in Spain, their main contributions in the recent years and the main focus of interest these days. This description is classified in five main areas: audio processing including speech, speaker characterization, speech and language processing, text to speech conversion and spoken language applications. This paper also introduces the Spanish Network of Speech Technologies (RTTH. Red Temática en Tecnologías del Habla) as the research network that includes almost all the researchers working in this area, presenting some figures, its objectives and its main activities developed in the last years.
Polytonia
Authors: Mertens Piet
Published: March 2021

This paper first proposes a labeling scheme for tonal aspects of speech and then describes an automatic annotation system using this transcription. This fine-grained transcription provides labels indicating pitch level and pitch movement of individual syllables. Of the five pitch levels, three (low, mid, high) are defined on the basis of pitch changes in the local context and two (bottom, top) are defined relative to the boundaries of the speaker’s global pitch range. For pitch movements, both simple and compound, the transcription indicates direction (rise, fall, level) and size, using size categories (pitch intervals) adjusted relative to the speaker’s pitch range. The automatic tonal annotation system combines several processing steps: segmentation into syllable peaks, pause detection, pitch stylization, pitch range estimation, classification of the intra-syllabic pitch contour, and pitch level assignment. It uses a dedicated and rule-based procedure, which unlike commonly used supervised learning techniques does not require a labeled corpus for training the model. The paper also includes a preliminary evaluation of the annotation system, for a reference corpus of nearly 14 minutes of spontaneous speech in French and Dutch, in order to quantify the annotation errors. The results, expressed in terms of standard measures of precision, recall, accuracy and Fmeasure are encouraging. For pitch levels low, mid and high an F-measure between 0.946 and 0.815 is obtained and for pitch movements a value between 0.708 and 1. Provided additional modules for the detection of prominence and prosodic boundaries, the resulting annotation may serve as an input for a phonological annotation.
Prosody as a recursive embedding tool in production and perception of karajá
Authors: Gomes Juliana Novo , França Aniela Importa , Maia Marcus , Rilliard Albert
Published: March 2021

Hierarchical or indirect recursion can be found in different domains of human language and thus, it has been claimed to be the only part of language that is specific to humans (Hauser, Chomsky, and Fitch 2002). However, in the past decade, both the claims that, recursion is the central component of the “narrow faculty of language” and that, it should be present in all languages have been the object of intense debate (cf. Pinker & Jackendoff, 2005; Everett, 2005). This debate triggered the exploration of new frontiers in the examination of embedded structures, which have been examined in acquisition and in processing and have been shown to be implemented through a wide array of linguistic resources in different languages. This paper presents an acoustic description and a neuro-psycholinguistic analysis (ERP/EEG) of an uncommon cognitive device to embed relative clauses. It is implemented in Karajá, a Macro-Je language spoken in Central Brazil, which uses pitch accent to signal relativization: (i) [tori do‟rode] „the white man arrived‟ versus (ii) [tori doro‟de] „the white man who arrived‟, first described in Ribeiro as stress shift (2006). The major interest in studying this phenomenon is because in Karajá, more than structuring envelopes for acts of speech, prosody codes directly onto the central syntactic algorithm of recursion. We found evidence in favor of a stronger facilitation to process a coordinated structure than a recursive structure. We found smaller RTs and amplitudes in the EEG related to the coordinated conditions versus the embedding conditions. Also, it seems that even though embedding is harder to launch, hierarchical structuring makes it easier to process in the third embedding, when comprehenders learn they are in an embedding mode. Coordination, on the other hand, being a default, is easier to launch, but it seems to become progressively harder as it does not benefit from hierarchical structuring.
exílio chileno de Mário Pedrosa
Authors: Paladino Luiza Mader
Published: March 2021

Com base em uma ampla pesquisa de fontes primárias em arquivos de instituições no Brasil e no Chile, este artigo apresenta um panorama sobre o exílio chileno de Mário Pedrosa, durante o Governo Salvador Allende (1970-1973). Busca-se analisar as principais iniciativas culturais fomentadas pela Unidade Popular, uma coligação de partidos de esquerda, com objetivo de compreender a conjuntura na qual o autor brasileiro foi convocado. Pedrosa fez parte de um contingente de intelectuais latino-americanos exilados que colaborou ativamente na área acadêmica e, de forma ainda mais direta, na política cultural chilena, ao ser convidado para conceber o Museu da Solidariedade. Seguramente, essa instituição, formada exclusivamente por obras doadas, foi o empreendimento mais importante do governo popular, no entanto essa entidade inseriu-se em um programa cultural e político mais amplo, sendo necessário compreender o contexto geral no qual Pedrosa filiou-se. Apesar de ter se envolvido diretamente na criação do Museu, foi nas cooperativas de artesanato que Pedrosa enxergou o maior potencial comunitário da arte, cujo caráter revolucionário o crítico exaltou no artigo "Arte Culta e Arte Popular", escrito em 1975.
dupla exclusão

As narrativas já institucionalizadas sobre o movimento concretista no Brasil e suas reverberações abrangem referências internacionais para os artistas integrantes do movimento, e os conflitos de hegemonia cultural entre os dois polos econômicos do país na época: Rio de Janeiro e São Paulo. A considerável produção analítica sobre o período e seus agentes tem sido uma das mais férteis dentro da historiografia da arte brasileira, abarcando críticos, manifestos, obras, artistas e locais de circulação – e no entanto, apenas recentemente alguns pesquisadores e curadores têm apontado o caráter machista de alguns membros dos grupos, e as dificuldade de consolidação profissional das artistas mulheres que participavam dos projetos e reuniões. Nesse sentido, Judith Lauand, a única artista mulher a participar oficialmente do grupo Ruptura em São Paulo, é caso emblemático dos movimentos de revisionismo histórico feminista, mas junto a ela temos também Jandyra Waters ocupando um lugar ainda frágil no sistema, sem o devido cotejamento.  Ainda que essas duas artistas tenham tido uma circulação considerável no meio artístico brasileiro, sua recepção crítica e inserção histórica não é a mesma de seus pares masculino, portanto, são casos que precisam ser revisitados a fim de esgarçar a malha historiográfica.

Este artigo pretende apresentar os resultados de um trabalho que articulou leitura e escrita literárias desenvolvido com alunos do Ensino Médio a partir dos contos A moça tecelã e Para que ninguém a quisesse, de Marina Colasanti. Fundamentada no caráter humanizador da literatura, tal como elaborado por Antonio Candido (2015), essa proposta possibilitou aos alunos tanto autonomia, legitimação dos seus posicionamentos de autores e estabelecimento de relações entre autoria feminina e representações femininas patentes na sociedade contemporânea pela voz de Marina Colasanti - que, numa ótica contra-hegemônica, evidencia tanto a violência simbólica quanto a emancipação e o autoconhecimento feminino.
PELOS (DES) CAMINHOS DA POESIA
Authors: Cavalcante de Matos Solange , Da Silva Nunes Raimunda , Cristina Testa Eliane
Published: March 2021

O presente texto trata-se de uma entrevista com o poeta marginal Pedro Tostes, o qual escreve poesias desde muito cedo, quando se descobriu no vasto mundo da escrita poética. É produtor cultural, mesmo não se considerando empreendedor no mercado da literatura, vive de poesia de forma audaciosa, resistente e marginal. Desde 2003, começou uma jornada pelo Brasil para levar sua poesia a diferentes locais como: feiras, universidades, congressos, espaços culturais diversos, etc., vivendo mediante a compreensão de que esta ação seria uma forma de “popularizar” a literatura. O escritor já tem vários livros publicados, sendo o útimo deles "Na Casamata de Si" (Patuá, São Paulo, 2018). Acreditamos que Tostes seja um poeta visionário e que não tenha medo de se expor, principalmente, em seus diferentes modos de ver a vida/poesia. Concebemos a poesia como um modo de trilhar muitas experiências estéticas, e Tostes tem experimentado amplamente com/a linguagem. Sabemos que viver de poesia no Brasil é um grande desafio, especialmente por se tratar de um “país com vários problemas nos campos educacional e cultural” (para usarmos as palavras de Tostes, obtida nesta entrevista). E mesmo diante de tal situação, Tostes tem incentivado os jovens a lerem e a se deixarem afetar pela poesia. Tostes pode ser relacionado à poesia marginal no sentido mais utópico e implicado à força da poesia para abrir (des)caminhos na vida, a começar pela ideia de ocupar as periferias, com saraus e Slams. Em seu último trabalho, “Na Casa Mata de Si” (Patuá/SP, 2018), Tostes nos mostra o seu lado de poeta “guerrilheiro” e chama a atenção, por meio de seus versos, para a guerra do “presente”, uma guerra, aliás, tanto interna como externa a nós. Em entrevista realizada via e-mail, Tostes nos faz revelações da sua vida como escritor e de muitos dos seus (des)caminhos no mundo da poesia.

Modern technologies in representation and preservation of the Kola Sami ethnic culture
Authors: Bodrova О.А. , Razumova I.А.
Published: March 2021

The paper is based on the latest comprehensive study of representations of the Sami people in Murmansk Region. The aim of the article is to describe and analyse the representations, which are considered as a product of the sociocultural practices which use specific technologies. The latter are regarded as methods and tools of practices aimed at preservation of ethnic culture, including its construction. The subject of this study is textual, visual, objective and animated forms of representations of the Sami culture, as well as interactive and other tech-nologies for imaging and branding of Murmansk Region, preservation of cultural heritage of the Sami, and market-ing of regional and ethnic products. For the first time, regional sociocultural practices of actualization and conser-vation of the tangible and intangible heritage have been analyzed using materials of the Kola Sami culture. The study involved ethnographic field research methods, content analysis of regional printed and network media, de-scription of expositions of the regional ethnographic museums, Sami private collections and archives. The analy-sis was based on the framework of constructivism methodology of ethnic studies, actor-network theory, sociology of things and memory studies. It has been determined that museums and mass media appear as collective au-thors of representations. The main commissioner of the technologies of representation and preservation of ethnic and cultural heritage of the Kola Sami of Murmansk Region is the regional government, which uses public and media practices as a managerial tool for the economic and social development of the Region. In the context of development of the ethnocultural tourism, the Sami historical and cultural heritage acts as a very attractive touris-tic resource which requires new sociocultural technologies, such as various forms of visualization and objectifica-tion of ethnic cultural elements, museumification and commercialization of material objects, symbolization and branding of the Sami culture. Sami self-presentations dominate in modern public space and discourse since 2010. At the same time, heteroethnic presentations demonstrate sustainable linguistic modes to describe and to portray Kola Sami people. Construction of cultural models results in reformatting of the Sami ethnic culture, changes of functionality of its elements, and appearance of new ethnocultural forms.

This article is concerned with the Chinese metal mirror, which, as it has been found during the study, has been stored for a long time in the collection of the Altai State Museum of Local Lore, but as yet has not attracted the attention of specialists and has not been introduced into scientific discourse. A special research has been required to determine the time and circumstances of its arrival to the museum, which involved working with the documentation of the Altai State Museum of Local Lore, stored both within the institute and in the State Archives of the Altai Territory. It has been concluded, that the mirror represents an occasional find and it came to the mu-seum in the first quarter of the 20th century from the Yenisei Province (currently, the southwestern part of Kras-noyarsk District. The article presents a detailed morphological characteristic of this artifact. The basis of the com-position in the ornamented part of the mirror is a stylized image of a single dragon. Its mouth is trying to grasp the holder, which symbolizes the “fire pearl”. The analysis of the specialised literature and catalogues showed that in Chinese mirrors such composition appeared only during the Tang Dynasty (618–907) and continued to exist dur-ing the Song Period (907–1279). It has been determined that the composition presented on such objects was reproduced for several centuries (Jin, Liao, and Yuan Dynasties), undergoing transformations associated with stylistic nuances (details of the image, shape of mirror, presence or absence of inscriptions) and size and quality of the objects. Based on the obtained data, the mirror from the Altai State Museum of Local Lore has been attrib-uted to the Yuan dynasty period. There are almost no analogies to such objects in Northern and Central Asia, despite the significant number of mirrors of the Mongolian time stored in collections of Siberian museums. There-fore, it seems possible to acknowledge the rarity of these very specimens; the fragmentarity of their distribution could possibly be explained by peculiarities of the history of specific craft centers that have yet to be investigated.
Firearms and weapon devices of the Russian army in 1582–1585
(based on materials from the settlement of Isker)

Archaeological materials found in different periods during the excavations in the settlement of Isker (Ku-chum, 17 km from the city of Tobolsk), the ancient capital of the Khanate of Sibir, allow the analysis of firearms of Russian warriors of the 1582–1585, who took part in the Yermak’s Conquest of the Khanate. Various gun barrel fragments, breechloader bolts, a hammer with a lock spring, steel strikers with turnscrews, metal and bone ram-rod parts, bullet moulds were discovered during the excavations in Isker. These findings suggest that Russian pishchal arquebuses with matchlocks of the first half of the 16th century were the major weapon in service. On the tips of wooden ramrods, there were copper and bone bushings for ramming the projectiles. Ramrods were also equipped with three-leafed bushing caps for bore cleaning. All-purpose steel strikers with turnscrews unscrewed the bolts that attached barrels to stocks and disassembled locks; they had holes to be suspended on the gun. Stone bullet moulds were used for moulding lead bullets. The carefully examined archaeological collections from Isker do not support the hypothesis proposed in scientific literature stating that Yermak’s Cossacks were armed with flintlock firearm and small-bore guns.

The main problem of archaeological plans drawn in the mid-20th century is that almost all of them have poor accuracy of spatial localisation of objects. Simple estimates show that the error relatively to the actual position of the site can reach several hundred meters on the Earth surface. Because of this, only large, well-preserved ob-jects can be identified using archaeological plans. If the monument is small and poorly preserved, then it is im-possible to distinguish it among modern buildings. This is especially critical if the search radius, which depends on the error in the archaeological plan, reaches 300–500 meters [Bolelov et al. 2019]. This situation complicates creation of modern accurate maps and geographical information systems. To specify the position of the monu-ments, we propose using maps of the General Staff of the USSR (GS), which contain the location details of a large number of archaeological sites. According to our estimate, the GS maps have an error of ca. 50 meters, which significantly reduces the search area. The idea is that, first, the site on the archaeological plan must be identified with the object on the map of the GS, and then the GS coordinates (SK-42) need to be recalculated to the WGS-84 ones of Google Earth. A simple method of conversion from the SK-42 coordinate system to WGS-84 and vice versa in the form of additive corrections to geographical coordinates is proposed. Estimates of random errors have been obtained, which are caused by the error in compiling and analysing the maps. Although numeri-cal estimates have been obtained for the territory of historical Khorezm, it is most likely that the same transforma-tions are applicable to other territories. The described technique has been successfully applied to the archaeo-logical sites of the Yakke-Parsan Channel, which, according to the map of E.E. Nerazik [2013, fig. 14], comprises 20 monuments. Of them, only six largest structures had an accurate identification. As a result of the research, we found and identified seven objects more. The comparison of coordinates made possible the preliminary identifica-tions, and final identifications were made after comparing the appearance of the objects with architectural plans. Other sites have not been found because they have not been preserved to our time. Nevertheless, the GS maps allow obtaining accurate coordinates of the lost monuments.
Brain Insulin Resistance: Focus on Insulin Receptor-Mitochondria Interactions
Authors: Pomytkin Igor , Pinelis Vsevolod
Published: March 2021

Current hypotheses implicate insulin resistance of the brain as a pathogenic factor in the development of Alzheimer’s disease and other dementias, Parkinson’s disease, type 2 diabetes, obesity, major depression, and traumatic brain injury. A variety of genetic, developmental, and metabolic abnormalities that lead to disturbances in the insulin receptor signal transduction may underlie insulin resistance. Insulin receptor substrate proteins are generally considered to be the node in the insulin signaling system that is critically involved in the development of insulin insensitivity during metabolic stress, hyperinsulinemia, and inflammation. Emerging evidence suggests that lower activation of the insulin receptor (IR) is another common, while less discussed, mechanism of insulin resistance in the brain. This review aims to discuss causes behind the diminished activation of IR in neurons, with a focus on the functional relationship between mitochondria and IR during early insulin signaling and the related roles of oxidative stress, mitochondrial hypometabolism, and glutamate excitotoxicity in the development of IR insensitivity to insulin.
Effect of Doping Cd1-xZnxS/ZnS Core/Shell Quantum Dot in Negative Dielectric Anisotropy Nematic Liquid Crystal p-methoxybenzylidene p-decylaniline

We report the effect of doping Cd1-xZnxS/ZnS core/shell quantum dot (CSQDs) in nematic liquid crystal p-methoxybenzylidene p-decylaniline (MBDA) at 0.05 wt/wt%, 0.1 wt/wt%, 0.15 wt/wt%, 0.2 wt/wt%, 0.25 wt/wt% and 0.3 wt/wt% concentrations of CSQDs in MBDA. Dielectric parameters with and without bias with respect to frequency has been investigated. The change in electro - optical parameters with temperature has also been demonstrated. The increase in the mean dielectric permittivity has been found due to large dipole moment of CSQDs which impose stronger interactions with the liquid crystal molecules. The dielectric anisotropy changes sign on doping CSQDs in MBDA liquid crystal. It was concluded that the CSQDs doping noticeably increases the dielectric permittivity of nematic MBDA in the presence of electric field. The doping of CSQDs in nematic MBDA liquid crystal reduces the ion screening effect effectively. This phenomenon is attributed to the competition between the generated ionic impurities during assembling process and the ion trapping effect of the CSQDs. The rotational viscosity of nematic liquid crystal decreases with increasing concentration of the CSQDs with faster response time observed for 0.05 wt/wt% concentration. The birefringence of the doped system increases with the inclusion of CSQDs in MBDA. These results find application in the field of display devices, phase shifters, industries and projectors.

The present study documented the presence of seagrass Halodule uninervis for the first time along with previously documented Halophila ovalis at Haripur creek. The population structure of both these seagrass species is assessed. The physico-chemical parameters were similar for both seagrass species except for the sediment grain size fractions. The sand content of H. ovalis patches was 1.2-fold higher than H. uninervis beds, whereas the silt content of H. uninervis beds was 2-fold higher than H. ovalis patches. The pH levels were lower than the standard oceanic pH of 8.2. Macroalgae like Ceramium sp. and Gracilaria verrucosa were growing on the leaves of H. uninervis due to high nitrate and phosphate levels of the creek waters. Leaf reddening was only observed in the leaves of H. ovalis. Under similar environmental conditions, H. ovalis (5004 ± 114.51 ind. m-2) had a 2-fold lower shoot density than that of the H. uninervis (11598 ± 187.52 ind. m-2). Both above- and below-ground biomass of H. ovalis (96.34 ± 10.18 and 197.5 ± 18.30 g DW m-2) was 2-fold lower than that of H. uninervis (198 ±7.45 and 456 ± 9.59 g DW m-2). H. uninervis leaves were 9-fold longer than that of H. ovalis, whereas H. ovalis leaves were 5-fold wider than H. uninervis. The leaf plastochrone interval is 2.3 days for H. ovalis and 9.6 days for H. uninervis. Consequently, the leaf growth rate of H. ovalis is 2-fold lower than that of H. uninervis. H. ovalis had 2.6-fold longer internodes than H. uninervis. The root length of H. uninervis was longer than H. ovalis. Consequently, the shorter root length of H. ovalis led to higher branching frequency than H. uninervis. The total C and N content were higher in the leaves of H. ovalis than H. uninervis.
