Published: May 2021

Today oil industry faces a lot of problems and lost money during drilling and completion operation, so that the studies and researches must including the ways and solutions that lead to decrease the costs.

    In this research we tried to find local alternative material instead of foreign drilling fluid materials that is used in drilling fluids and will help to save a lot of money by decrease oil well drilling cost because of the high cost of drilling fluid materials which represent now about 30 % of total cost for drilling oil well.    

The local alternatives is Ore polymers ( plant origin)  called : TRAGACANTH GUM.

In this study we investigated the local material and tested it under API Specification for Drilling Fluids Materials. Also tested sample of mud after add local material (TRAGACANTH GUM.) for weighted concentrations (0.5, 1.5, 2, 2.5 and 3 gm.) to show physical and rheological properties.  

The third part of this study tested sample of mud after add local material (TRAGACANTH GUM.) under different temperatures values and up to 70°C (this temperature is near for some formations temperature  in Iraqi oil fields ) to show temperature effect on this material.

 A comparison between the local alternative and similar foreign materials for same sample was done to show physical and rheological properties. The results approved that, the local alternatives can used as filtration control materials for water based drilling fluid. Also the  local alternatives increased viscosity as minimal for water based drilling fluids, So it can be used as part alternative for Bentonite to increase viscosity by increasing Yield point and decreasing solids concentration in drilling fluids so it have  positive effect to save Rig equipment’s and Pay-zone.

Research includes the study of the North West Extensions of Makhul structure using remote sensing techniques (central Iraq) which is located to the north of Baiji province in  Salahuddin governorate, which lies 240 kilometers north of the city of Baghdad, located within the operations of the North Oil Company.

  The aim of the present study is to re-define extensions of Makhul structure by the use of visual space (satellite systems and landsat7 ETM) after it was observed that there is a difference for determined the North West Extensions for structure of what is mentioned in previous studies.

   I have been using the space visuals and available previous studies for the Makhul structure and North Western Extensions him in determining the dimensions, in addition to the show faults in the research area  and relations with the Makhoul structure  and its extensions. It has also been taking the results of wells drilled in the research area (Makhul -1, 2 and Mityaha -1),  for the purpose of assessing hydrocarbon reservoir, and we are relying on the explanatory information from the images and spatial data and received from the satellite (LANDSAT 7) according to the system ETM (Enhasment Thematic Mapper). It has also rely on the definition and identification of some units geomorphologic home on the intensity of the color, tone and texture. a network of drainage pattern is essential.

    Using satellite data and previous studies point showing that the length of the Makhul  structure more than 95.500 km and not 37 km, and the area affected by the operations raise distinct and different stages. it has been divided into four parts of  Makhul structure (from the southeast to the northwest), a south-eastern part, part crescent, which includes the Saded structure, the middle part, which includes the Cehel structure and north-western part, which includes the Mityaha structure. The hydrocarbon possibilities in the study area, it is in spite of the weakness of the possibilities hydrocarbon in the southeastern part of the Makhul structure (wells Makhul-1,2) and the northwestern part formerly known the Mityaha structure (well Mityaha -1), but the middle part (the structure Cehel areal) may be possibilities hydrocarbon better and more possibilities from the other parts.

Aim of the study was to investigate the risk of developing type 2 diabetes mellitus (T2DM) in individuals with metabolically healthy and unhealthy obesity phenotypes (MHO and MUO) and evaluate the contribution of metabolic syndrome (MS) components to the 12-year risk of developing T2DM according to a prospective study.

Material and methods. The study included 1958 people with a BMI ≥30 kg/m² and no T2DM, from among those examined at the baseline screening in 2003– 2005 of the HAPPIE project. New cases of T2DM were diagnosed between 2003 and 2018 according to the register of diabetes mellitus and repeated screenings. The median follow-up period was 12.1 years. Were used to define MHO: criteria of the NCEPATP III, 2001 and IDF, 2005.

Results. The incidence of T2DM in the MHO group according to all studied criteria is on 1,5 times lower than in persons with MUO, p<0,001. According to the results of Cox regression multivariate analysis, the risk of developing T2DM in individuals with MHO is 2.3 times lower according to the IDF criteria, 2005 and 2,2 times lower according to the NCEP ATP III, 2001 criteria, compared with persons with MUO. The risk of developing T2DM increases in direct proportion to the number of MS components: 3 components—OR = 3,1 (95% CI: 1.0; 9.9), p = 0.048, 4 components—OR = 4.4 (95% CI: 1.4; 14.0), p = 0.011. However, the presence of obesity in a person with one risk factor does not lead to the development of T2DM within 12 years, p>0.05. When analyzing obese individuals who had abdominal obesity (AO), the risk of developing T2DM is 2 times higher compared to individuals with normal waist circumference (WC), and people without AO demonstrate no risk of developing T2DM, with an increase in the number of MS components, p> 0.05.

Conclusions. The incidence of first-­onset T2DM during 12 years in the MHO group by any used criteria is on 1.5 times lower than in the MUO group. In individuals with obesity, regardless of its phenotype, the most significant independent predictors of the risk of incident T2DM are AO and fasting hyperglycaemia. In individuals without AO, the risk of developing T2DM does not increase, even with an increase in the number of MS components. In the presence of AO, the risk of developing T2DM increases 2 times already with the appearance of any other component.

Introduction to Special Collection: Social Science and the Social Life of Plastic
Authors: Steger Brigitte , O’Hare Patrick , Perez Teresa Sandra
Published: May 2021

Concern around plastic pollution and China’s ban on receiving foreign waste and recyclate have refocused attention on responsible waste management and attracted interdisciplinary research that impacts policy and practice. Consequently, plastic has elevated the role of social science in the innovation space, which has traditionally been occupied by science and enterprise. This opening article marks the launch of a special collection of works, which will be published monthly, on the social life of plastic. As a preface to the forthcoming contributions, this introduction highlights the value of humanities and social science approaches to tackling plastic waste, tracing the directions that the social science of waste and plastic has taken and can take in future. Concomitantly, it helps to steer discussions and collaborations away from the restricted realm of plastic bag consumption towards a deeper engagement with socio-material processes. We thus contribute to ensuring that the current anti-plastic zeitgeist is situated in space and time, and that potential solutions benefit from a rigorous examination of the multiplicity of plastics.

Published: May 2021

O objetivo desta pesquisa foi mapear as áreas verdes urbanas do município de Castelo-ES e propor sugestões para melhorias na arborização local. Um Sistema de Informação Geográfica foi usado para analisar imagens aéreas de alta resolução espacial em conjunto a informações cartográficas. Procedimentos de fotointerpretação das áreas verdes foram realizados na escala de 1:1000. A distribuição da arborização urbana foi espacializada conforme a localização por bairros, sendo quantificada por meio do Índice de Áreas Verdes (IAVT) e Índice de Áreas Verdes Recreativas (IAVR). Ao longo do período estudado, a arborização decresceu 67% nos bairros da cidade. Embora os Índices de Áreas Verdes quantificados sejam considerados satisfatórios, estando acima do mínimo exigido pela Organização Mundial da Saúde (OMS) e Sociedade Brasileira de Arborização Urbana (SBAU), eles decresceram no período de análise. O IAVR estimado não foi satisfatório, sendo um problema para o planejamento urbano. As áreas verdes estão concentradas principalmente em locais não efetivamente urbanizados. A execução de melhorias na arborização das vias públicas e a criação de novos parques/praças são medidas necessárias para aumentar a qualidade de vida e do ambiente.
A PRODUÇÃO NORMATIVA SOBRE ARBORIZAÇÃO URBANA NA CIDADE DE SÃO CARLOS (SP)
Authors: Caiche Daniel Tonelli , Peres Renata Bovo
Published: May 2021

Nos últimos anos vem ocorrendo um aumento da produção de conhecimento sobre os benefícios ecológicos, econômicos, culturais e sociais da arborização, o que demonstra a força do tema e suas possibilidades diversas. Todavia, em menor número são os estudos dedicados a relacionar a arborização com o processo de urbanização e com a produção de normas. O objetivo deste trabalho foi aprofundar o conhecimento sobre o processo de normatização da arborização urbana na cidade de São Carlos (SP). Para tal, utilizou-se uma abordagem qualitativa de pesquisa, denominada pesquisa documental. Foram identificadas 27 (vinte e sete) normas sobre Arborização Urbana de São Carlos, sendo a maior parte das normas produzidas durante a primeira década dos anos 2000. Há um equilíbrio entre normas produzidas pelos poderes executivo e legislativo. A maioria das normas utilizam o termo “árvore” na ementa, quando comparada com o termo “arborização”. As duas categorias que mais apresentaram normas foi a de “Planejamento” e “Cultural”. A categoria “Econômica” foi a que menos apresentou normas. Os resultados encontrados demonstram aumento de interesse da temática materializada na produção de instrumentos normativos. Porém foram identificadas rupturas e lacunas na continuidade da formulação de normas que demonstram a necessidade de aperfeiçoamento normativo.

Published: May 2021

A arborização urbana é indispensável para a população de um município, pois traz benefícios como a diminuição da radiação solar, de enchentes, de dióxido de carbono e o aumento da umidade do ar. O estudo realizou o inventário da arborização urbana nas praças de Caraguatatuba-SP. Os componentes arbóreos foram identificados taxonomicamente e classificados de acordo com o porte, disposição e densidade de distribuição. As espécies foram categorizadas em nativas ou exóticas e classificadas segundo a lista de espécies da flora do Brasil ameaçadas de extinção. Os equipamentos urbanos presentes foram inventariados. Identificou-se 59 praças no município. Foram inventariados 2.233 indivíduos arbóreos, pertencentes a 161 espécies, 30 ordens e 69 famílias botânicas, apresentando diversidade H’=4,16. As ordens mais abundantes foram Arecales (27%), seguida por Myrtales (8,7%) e Aspagarales (8,4%). O porte arbóreo foi o mais abundante (37%), seguido de arbustos (34%) e herbáceas (17%). A densidade arbórea da disposição vegetal nas praças foi de agrupados em (43%) seguido por parcialmente isolado (42%) e isolado (15%). A disposição dos indivíduos foi casual (32%), difusa (29%) e pontual (23%). Dentre as espécies apenas 30% são nativas. Foram identificadas quatro espécies com diferentes graus de ameaçadas na Lista Vermelha da União Internacional para Conservação da Natureza. Quanto ao mobiliário presente, verificou-se que a iluminação pública está presente em 28% das praças, bancos em 22% e lixeiras em 21%. Apesar do alto índice de diversidade faz-se necessário o enriquecimento nos plantios das áreas urbanas, priorizando-se espécies nativas e consequentemente aumentando assim os serviços ecossistêmicos.

Os índices ecológicos são indicadores que podem ser uma ferramenta do manejo e plano diretor da arborização urbana. O objetivo desta pesquisa foi analisar índices de diversidade da arborização de ruas com o intuído de contribuir à gestão da floresta urbana de Boa Vista-RR.  Primeiramente realizou-se o cadastro censitário da arborização de ruas e, posteriormente a análise da diversidade ecológica, utilizando os índices de Diversidade de Shannon-Weaver (H’), Diversidade Máxima (Hmáx), Diversidade Ecológica de Simpson (C), Equabilidade de Pielou (E), Coeficiente de mistura de Jentsch (QM) e Riqueza de Odum (d1). Os índices foram comparados e analisados em relação as zonas administrativas da cidade e a outras cidades brasileiras. Foram cadastrados 6.907 indivíduos nas calçadas distribuídas em 91 espécies diferentes. O índice de diversidade de Shannon-Weaver (H’) obtido na Zona Leste foi de 2,79, sendo o maior entre as zonas da cidade. O índice de Diversidade Ecológica de Simpson (C) foi de 0,11 e Índice de Equabilidade de Pielou (E) foi de 0,58, para toda a cidade. O Coeficiente de Mistura (QM) foi melhor para a Zona Leste (0,07). O índice de Odum variou entre 4,93 a 8,2. Conclui-se que a Zona Leste apresentou os melhores índices de diversidade. Diante dos resultados obtidos, recomenda-se o plantio de diferentes espécies nas Zonas Central e Sul da cidade.
Tillage effects on soil properties, crop responses and root density of sweet pepper (Capsicum annuum)
Authors: Grasso Rafael , Peña-Fleitas M. Teresa , Gallardo Marisa , Thompson Rodney B. , Padilla Francisco M.
Published: May 2021

Aim of study: Soil compaction causes an increase in bulk density, resistance to penetration, low diffusion of oxygen and water in the soil. Tillage is one of the techniques to alleviate compaction. The objective of this work was to evaluate the effects of tillage on sweet pepper grown in greenhouse soil.Area of study: The experimental work was conducted in a plastic greenhouse at the Experimental Station of the University of Almería (SE Spain).Material and methods: The soil was ploughed with a single pass with ripper to 15 cm depth and with rotavator to 10 cm depth. The control treatment was soil untilled. Crop dry matter production and root length growth and density of sweet pepper were evaluated, in addition to soil characteristics such as bulk density, resistance to penetration and soil matric potential.Main results: Tillage reduced soil bulk density from 1.70 to 1.60 kg L-1 in the 10-40 cm of soil depth. There was a notable reduction in irrigation (12%), total N applied (13%), drainage (91%) and N leaching (95%) in the tillage treatment. However, tillage did not improve significantly crop dry matter production and yield. The absence of tillage effect is possible due to a slight reduction in the bulk density of the soil.Research highlights: The tillage treatment produced a notable reduction in irrigation, total N applied, drainage and N leaching when compared to the control.

Authors: Marchewka Jakub , Marchewka Wojciech , Golec Edward
Published: May 2021

Introduction: Distal radius fractures (DRFs) are among the most commonly seen types of fractures worldwide. Numerous studies suggested that surgical treatment of DRFs results in better quality of life. Objectives: The aim of this study was to assess long-term quality of life after operative and nonoperative treatment of distal radius fractures among adults. Material and methods: We retrospectively studied 207 patients with isolated DRF (mean age 64 ±17.9 years, women comprised 150 (72.5%), men 57 (27.5%). There were no significant differences in sex, age, hand dominancy, energy of trauma, AO type fracture and comorbidities between patients treated operatively (n=101) and nonoperatively (n=106). After 3.9 ±1.6 years (mean ±SD) quality of life assessment was conducted using Short Form Health Survey (SF-36) and International Osteoporosis Foundation Quality of Life Questionnaire (IOF QLQ). Functional outcomes were evaluated using Disabilities of the Arm, Shoulder and Hand (DASH) and Patient Rated Wrist Evaluation (PRWE) questionnaires. Results: Quality of life in operatively treated distal radius fracture patients was better than amongst those treated nonsurgically. However, after subdivision of cohorts we observed no such differences regardless of treatment method in patients aged ≥ 50 years. SF-36 and IOF QLQ scores were correlated with DASH and PRWE results. Conclusions: Quality of life questionnaires are useful tools for determining outcomes after distal radius fractures. Operative treatment may not always be superior to nonoperative management especially in patients aged 50 years or above with distal radius fractures.

Authors: Hocaoglu Cicek
Published: May 2021

The new type of coronavirus disease (COVID-19), which has affected the whole world and resulted in many people’s death, has also had negative effects on mental health. The measures, restrictions, and quarantine practices taken to control the pandemic have caused psychological, social, and economic problems. In studies conducted to date, it has been stated that anxiety symptoms, depression, severe adaptation, and sleep disorders are observed in people who have lost their relatives due to COVID-19, who were treated with the diagnosis of COVID-19, or who were exposed to intense information pollution related to the pandemic. It is also known that a large number of people lost their jobs due to the pandemic, and unemployment rates increased in countries. Economies and health systems of many countries are under this significant burden. In addition to the increase in the incidence of mental symptoms and disorders associated with COVID-19, growing socioeconomic problems pose a risk for suicide. In studies on the subject, attention is drawn to the rate of suicide that will increase during and after the pandemic, and warnings are given about taking precautions. In this section, the effects of COVID-19 on suicidal behavior will be discussed in light of findings in the literature.
Una investigación sobre las tutorías compartidas
Authors: Saiz Linares Ángela , Ceballos López Noelia
Published: May 2021

RESUMEN Esta investigación tiene por objetivo analizar, desde una perspectiva etnográfica, un caso paradigmático de “escuela orientadora” que sitúa la Acción Tutorial como pilar sobre el que apuntalar diferentes acciones y propuestas educativas a partir de un proyecto de Tutorías Compartidas. En este trabajo de investigación examinamos algunas claves que permiten tender puentes entre la definición canónica de Acción Tutorial y el proyecto educativo de esta escuela. Las técnicas de producción de información han sido: observación participante, grupos de discusión con docentes (tutores, orientadora y equipo directivo) y con alumnado de Educación Primaria (desde 1º a 6º), entrevistas semi-estructuradas con tutores y análisis documental (PEC, PAT y PIIE). A partir de un análisis de contenido tratamos de dar vida a los presupuestos que la literatura ha confirmado como irrenunciables: institucionalizar oportunidades de convivencia internivelares y con la comunidad; trabajar consistentemente las dimensiones personales, educativas, profesionales y socio-cívicas; crear tiempos y espacios destinados al intercambio reflexivo entre profesionales educativos. Concluimos confirmando que la interseccionalidad de las acciones analizadas permite abordar sistemáticamente las dimensiones que vertebran los proyectos de Acción Tutorial.ABSTRACT This research aims to analyze, from an ethnographic perspective, a paradigmatic case of a “counselling school” that places Tutorial Action as a pillar on which different educational actions and proposals are based. In this research we examine some keys that allow us to build bridges between the canonical definition of Tutorial Action and the educational project of this school. The techniques of information production were: participant observation, focus groups with teachers (tutors, counsellor and management team), and primary school students (from 1st to 6th grade), semi-structured interviews and document analysis. From a content analysis we try to give life to budgets that literature has confirmed as indispensable: institutionalize opportunities for internivelar coexistence and with the community; consistently work on personal, educational, professional and socio-civic dimensions; create times and spaces for reflective exchange between professionals. We conclude by confirming that the intersectionality of the actions analyzed allows us to work consistently on the dimensions that structure the Tutorial Action projects.
La revocación del mandato en las democracias de América Latina
Authors: Garrido López Carlos
Published: May 2021

La revocación del mandato ha sido, hasta hace unas décadas, un mecanismo de democracia directa poco extendido y apenas usado fuera de EE.UU. La crisis de la representación y del sistema de partidos que padecieron varios países latinoamericanos condujo, sin embargo, a reparar en la revocación del mandato como una vía adicional de participación y control de los ciudadanos que podría estimular la receptividad y la responsabilidad de las autoridades electas. Y de ser una institución apenas conocida, la revocación se ha extendido a varios de los países latinoamericanos más importantes, al punto de convertirse en una de las señas distintivas de la región. En este trabajo se realiza un estudio comparado de la revocación del mandato en Argentina, Colombia y Perú, donde se ha limitado a las autoridades regionales y locales. Se analizan, asimismo, la revocación de los diputados y autoridades locales por decisión de los partidos y a iniciativa y votación popular en Panamá; la revocación en Ecuador, Venezuela y Bolivia, donde la institución se ha extendido a todos los cargos electos, incluido el presidente de la República; y la revocación del presidente y de los gobernadores de los entes federados en México tras la reforma constitucional impulsada en 2019 por López Obrador. El trabajo concluye con un balance de los diseños institucionales de la revocación del mandato, en el que se subraya la tensión existente entre el proyecto normativo y sus condiciones de realización.The recall was, until recent decades, a tool of direct democracy that was hardly known or used outside the United States. However, the crisis of representation and of the party system that several Latin American countries suffered led to recover the recall as an additional form of citizen participation and control that could boost receptivity and responsibility of elected authorities. In only three decades, the recall has moved from being barely known to spreading to the most important Latin American countries and becoming one of the distinctive features of the region. In this work we present a comparative study of the recall in Argentina, Colombia and the Republic of Peru, where it was limited to regional and local authorities. We also analyse the recall of local legislators and authorities by decision of the political parties and popular vote in Panama; the recall in Ecuador, Venezuela and Bolivia, where this institution has spread to all elected offices, including the president of the republic; and the recall of the president and governors of the federal entities of Mexico after the constitutional reform promoted by López Obrador. This work ends by assessing the institutional designs of the recall, where we emphasize the tension between draft legislation and its conditions for implementation.

¿Viaje desde el encantamiento hasta el desencantamiento? Un estudio sobre las descripciones de la naturaleza de Darwin desde el Journal hasta el Origin
Authors: Jiménez Pazos Bárbara
Published: May 2021

Teniendo en cuenta la cuestión en disputa sobre el encantamiento o el desencantamiento del mundo causado por la ciencia moderna, este artículo examina comparativamente la semántica del léxico en Journal of Researches y The Origin of Species de Charles Darwin utilizando estrategias de minería de textos. El objetivo es mostrar que existe un camino semántico directo, comenzando en Journal y culminando en Origin, que confirma una tendencia hacia un tipo de lenguaje desencantado empleado por Darwin en sus descripciones de la naturaleza. Esto queda demostrado por el análisis léxico y semántico de ambos textos.

Taking into accountthe disputed question about enchantment or disenchantment of the world caused by modern science, this paper comparatively examines the semantics of the lexicon of Charles Darwin’s Journal of Researches and The Origin of Species using the software package Wordsmith Tools. Its aim is to show that there is a direct semantic path, starting with the Journaland culminating in the Origin, which confirms a tendency towards a gradually disenchanting, in a non-pejorative sense, type of language used by Darwin in his descriptions of nature. This is demonstrated by the lexical and semantic analysis of the texts.

El siguiente trabajo profundiza el acontecimiento del duelo en la filosofía de Jacques Derrida. En esta perspectiva, se comienza por el libro Glas de 1974, donde se anunciaría el duelo por la muerte del sentido. Posteriormente, se profundizará en los fantasmas derridianos y la responsabilidad con los desaparecidos. En tercer lugar, emerge la figura del don, que abre al duelo hacia la espera infinita. Finalmente, y desde la lectura derridiana de los psicoanalistas Abraham y Török, se trabajará la figura de la “cripta” como falso inconsciente. Se concluye con una reflexión sobre Chile y los desaparecidos por la dictadura de Pinochet.

This article focus on the event of mourning in the philosophy of Jacques Derrida. It begins, accordingly, with the 1974 book Glas, where Derrida announces his mourning for the death of meaning. The article then focus on the Derridean ghosts and the responsibility towards the missing. Thirdly, the figure of gift emerges, one that opens mourning towards the infinite hold. Endly, from the Derridean lecture of phsychoanalysts Abraham and Török, the figure of “crypt” will be presented as a false inconscious.

Objetivo: Analizar los efectos psicológicos que la actual pandemia de coronavirus (covid19) está teniendo en los profesionales del ámbito sanitario.Métodos: Estudio descriptivo de corte transversal en una muestra de 1150 profesionales del ámbito sanitarios, seleccionados al azar. Las mediciones y los resultados se explicaron con el modelo teórico el Diferencial Semántico propuesto por Osgood.Resultados: Se ha encontrado que, en general, el personal del ámbito sanitario se siente muy desprotegido, con miedo y estresado. Confieren más miedo al autocontagio que al contagio de otros. Perciben su trabajo como eficaz, beneficioso, activo, útil y flexible, y simultáneamente se siente amable, afectivo, sincero, cálido y discreto. Encontramos que las enfermeras, y después los técnicos en cuidados enfermeros se sienten más útiles, valientes, importantes y sinceras que otras categorías sanitarias, entre las que figuran los y las médicos/as. Las emociones que sentían el personal sanitario están fuertemente influidas por la orientación política que tuvieran.Conclusión: El estudio realizado sobre el efecto psicológico de la actual pandemia en los profesionales del ámbito sanitario aporta diferencias significativas en función de la profesión, el contrato laboral, el sexo y la orientación política de los entrevistados.

Measurements and results were explained with the theoretical model of the Semantic Differential proposed by Osgood.Results: It has been found that, in general, healthcare professionals feel very unprotected, afraid and stressed. They were more afraid of self-contagion than of others. They perceived their work as effective, beneficial, active, useful and flexible, and at the same time, they feel kind, affective, sincere, warm and discreet. We found that nurses, and later, nurse care technicians feel more useful, brave, important, and sincere than other healthcare categories, including physicians. The emotions that the health personnel felt were strongly influenced by their political orientation.Conclusion: The study carried out on the psychological effect of the current pandemic on health professionals provides significant differences depending on the profession, the employment contract, the sex and the political orientation of the interviewees.

Depuis au moins une dizaine d’années, les médias télévisuels font la promotion d’idées reçues sur les gestes et les expressions faciales. Des séries policières présentent l’analyse de la communication non verbale comme un outil qui, pour les professionnels de la justice, permettrait de distinguer efficacement la vérité des mensonges. De plus, des intervenants, présentés explicitement ou non comme des body language experts, proposent des « décryptages » du non-verbal de personnalités publiques. Toutefois, quelle est la nature de l’information véhiculée par de tels « décryptages » et comment, en pratique, peuvent-ils nuire à la bonne administration de la justice ? Pour répondre à cette question, nous avons analysé de façon minutieuse et approfondie un « décryptage » d’Aaron Hernandez lors de son procès. Les résultats de notre analyse montrent comment l’intervenante (a) fait parler implicitement les comportements non verbaux d’Hernandez, obligeant alors les téléspectateurs à reconstruire ce qu’elle laisse entendre, et (b) fait indirectement la promotion d’idées reçues sur la communication non verbale qui peuvent fausser l’appréciation de la preuve par les juges et les jurés. Les résultats sont discutés à l’aide de la littérature scientifique sur la communication non verbale et la détection du mensonge.

Biomarkers of low-grade inflammation have been associated with susceptibility to a severe infectious disease course, even when measured prior to disease onset. We investigated whether metabolic biomarkers measured by nuclear magnetic resonance (NMR) spectroscopy could be associated with susceptibility to severe pneumonia (2507 hospitalised or fatal cases) and severe COVID-19 (652 hospitalised cases) in 105,146 generally healthy individuals from UK Biobank, with blood samples collected 2007–2010. The overall signature of metabolic biomarker associations was similar for the risk of severe pneumonia and severe COVID-19. A multi-biomarker score, comprised of 25 proteins, fatty acids, amino acids, and lipids, was associated equally strongly with enhanced susceptibility to severe COVID-19 (odds ratio 2.9 [95%CI 2.1–3.8] for highest vs lowest quintile) and severe pneumonia events occurring 7–11 years after blood sampling (2.6 [1.7–3.9]). However, the risk for severe pneumonia occurring during the first 2 years after blood sampling for people with elevated levels of the multi-biomarker score was over four times higher than for long-term risk (8.0 [4.1–15.6]). If these hypothesis generating findings on increased susceptibility to severe pneumonia during the first few years after blood sampling extend to severe COVID-19, metabolic biomarker profiling could potentially complement existing tools for identifying individuals at high risk. These results provide novel molecular understanding on how metabolic biomarkers reflect the susceptibility to severe COVID-19 and other infections in the general population.

Rainfall prediction is immensely crucial in daily life routine as well as for water resource management, stochastic hydrology, rain run-off modeling and flood risk mitigation. Quantitative prediction of rainfall time series is extremely challenging as compared to other meteorological parameters due to its variability in local features that involves temporal and spatial scales. Consequently, this requires a highly complex system having an advance model to accurately capture the highly non linear processes occurring in the climate. The focus of this work is direct prediction of multistep forecasting, where a separate time series model for each forecasting horizon is considered and forecasts are computed using observed data samples. Forecasting in this method is performed by proposing a deep learning approach, i.e, Temporal Deep Belief Network (DBN). The best model is selected from several baseline models on the basis of performance analysis metrics. The results suggest that the temporal DBN model outperforms the conventional Convolutional Neural Network (CNN) specifically on rainfall time series forecasting. According to our experimentation, a modified DBN with hidden layes (300-200-100-10) performs best with 4.59E−05, 0.0068 and 0.94 values of MSE, RMSE and R value respectively on testing samples. However, we found that training DBN is more exhaustive and computationally intensive than other deep learning architectures. Findings of this research can be further utilized as basis for the advance forecasting of other weather parameters with same climate conditions.
Braincase anatomy of the Paleocene crocodyliform Rhabdognathus revealed through high resolution computed tomography
Authors: Erb Arthur , Turner Alan H.
Published: May 2021

Dyrosaurids were highly specialized, largely marine, relatives of living crocodylians, and one of the few archosaur lineages to survive the K-Pg extinction. Dyrosaurids lived during the Cretaceous to the Eocene and represent a unique combination of morphology and ecology not seen in living crocodylians. Little is known about their endocranial anatomy, leaving many questions about their neurosensory adaptations unaddressed. Recently, µCT (micro-computed tomography) scans were made of a well-preserved skull of Rhabdognathus, a Paleocene dyrosaurid from Mali. This marks the first time the braincase and neurosensory features of a dyrosaurid have been examined using CT. We focus our attention to three specific internal structures: the cranial endocast; the inner ear; and the paratympanic sinuses. The cranial endocast of Rhabdognathus revealed novel features including a unique conformation of its paratympanic system, a prominent dorsal venous system that communicates with the external skull table, extremely enlarged tympanic vestibules that meet at the midline of the endocranium, a prominent spherical cerebrum, and elongate olfactory tracts accounting for half the total endocast length. The bizarre laterally facing lateral Eustachian foramen of dyrosaurids is now understood to be a complex fossa including both a ventrally directed lateral Eustachian foramen and a laterally directed foramen for the basioccipital diverticulum. A novel median pterygopharyngeal canal was discovered connecting the pharynx to the adductor chamber. These revelations require a reinterpretation of the associated external foramina visible on the posterior of the skull in dyrosaurids and potentially their close relatives the pholidosaurids. The olfactory tract terminates in an enlarged olfactory region possessing complex bony projections—a unique morphology perhaps serving to increase surface area for olfaction. The inner ear of Rhabdognathus exhibits characteristics seen in both Pelagosaurus and Gavialis. The vestibule is spherical, as in Gavialis, but is significantly expanded. The semicircular canals are enlarged but pyramidal in shape as in the thalattosuchian Pelagosaurus. The proportion of the cochlear length to total endosseous labyrinth height is roughly 0.5 in Rhabdognathus implying that the hearing capabilities resemble that of thalattosuchians. A suite of expanded sense organs (e.g., bony olfactory lamina; hypertrophied vestibule of the inner ear), and the clear expansion of the cerebrum to a more symmetrical and spherical shape suggest that dyrosaurids possess neuroanatomical modifications facilitating an agile predatory near-shore ecology.

Background

Ovarian cancer is one of the leading causes of female deaths worldwide. Ovarian serous cystadenocarcinoma occupies about 90% of it. Effective and accurate biomarkers for diagnosis, outcome prediction and personalized treatment are needed urgently

Methods

Gene expression profile for OSC patients was obtained from the TCGA database. The ESTIMATE algorithm was used to calculate immune scores and stromal scores of expression data of ovarian serous cystadenocarcinoma samples. Survival results between high and low groups of immune and stromal score were compared and differentially expressed genes (DEGs) were screened out by limma package. The Gene Ontology (GO), the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and the protein-protein interaction (PPI) network analysis were performed with the g:Profiler database, the Cytoscape and Search Tool for the Retrieval of Interacting Genes (STRING-DB). Survival results between high and low immune and stromal score groups were compared. Kaplan-Meier plots based on TCGA follow up information were generated to evaluate patients’ overall survival.

Results

Eighty-six upregulated DEGs and one downregulated DEG were identified. Three modules, which included 49 nodes were chosen as important networks. Seven DEGs (VSIG4, TGFBI, DCN, F13A1, ALOX5AP, GPX3, SFRP4) were considered to be correlated with poor overall survival.

Conclusion

Seven DEGs (VSIG4, TGFBI, DCN, F13A1, ALOX5AP, GPX3, SFRP4) were correlated with poor overall survival in our study. This new set of genes can become strong predictor of survival, individually or combined. Further investigation of these genes is needed to validate the conclusion to provide novel understanding of tumor microenvironment with ovarian serous cystadenocarcinoma prognosis and treatment.

The objective of this study is to identify the determinants of households’ food insecurity in rural areas in Mali, ranked among the most exposed to this phenomenon. The study used data from the national food security and nutritional survey in March 2016. The estimation of the econometric logit model by the maximum likelihood method revealed that regional location, age of household head, household size, level of education of the household head, welfare index and incomes’ diversification sources are the main determinants of households’ food insecurity in a rural area in Mali. The analysis shows that age of household head, size of household and practical of recession cropping affect positively food insecurity while the educational level of household head, welfare index and incomes ’diversification sources affect negatively food insecurity. These determinants are pillars on which policy maker might rely to reduce food insecurity. Therefore, it is desirable for government to orientate more the food insecurity fight programs towards the most affected regions, to prioritize households head with advanced age and those whose size is high, and promote recession cropping during the food insecurity fight plan, improve household education level, promote the household’s welfare and sensitize the households to diversify the sources of their income.
