Published: August 2021

Precipitable Water Vapor (PWV), as an important indicator of atmospheric water vapor, can be derived from Global Navigation Satellite System (GNSS) observations with the advantages of high precision and all-weather capacity. GNSS-derived PWV with a high spatiotemporal resolution has become an important source of observations in meteorology, particularly for severe weather conditions, for water vapor is not well sampled in the current meteorological observing systems. In this study, an empirical atmospheric weighted mean temperature (Tm) model for Guilin is established using the radiosonde data from 2012 to 2017. Then, the observations at 11 GNSS stations in Guilin are used to investigate the spatiotemporal features of GNSS-derived PWV under the heavy rainfalls from June to July 2017. The results show that the new Tm model in Guilin has better performance with the mean bias and Root Mean Square (RMS) of − 0.51 and 2.12 K, respectively, compared with other widely used models. Moreover, the GNSS PWV estimates are validated with the data at Guilin radiosonde station. Good agreements are found between GNSS-derived PWV and radiosonde-derived PWV with the mean bias and RMS of − 0.9 and 3.53 mm, respectively. Finally, an investigation on the spatiotemporal characteristics of GNSS PWV during heavy rainfalls in Guilin is performed. It is shown that variations of PWV retrieved from GNSS have a direct relationship with the in situ rainfall measurements, and the PWV increases sharply before the arrival of a heavy rainfall and decreases to a stable state after the cease of the rainfall. It also reveals the moisture variation in several regions of Guilin during a heavy rainfall, which is significant for the monitoring of rainfalls and weather forecast.

Authors: Ammar Islam Mohamed Magdi , Abdou Ahmed Mahmoud
Published: August 2021

Background

Clomiphene Citrate is considered the gold-standard for induction of ovulation and has been used for several years to treat PCOS related infertility. Unfortunately, 15-40% of women with PCOS are resistant to Clomiphene Citrate. The study aimed to evaluate potential benefits of adding the active form of Coenzyme Q10 (Ubiquinol) to Clomiphene Citrate compared with Human Menopausal Gonadotropins (hMG) in Clomiphene Citrate resistant PCOS patients. 148 PCOS Patients with Clomiphene Citrate resistance were randomized into two groups (A and B). In group A, controlled ovarian stimulation was done by Clomiphene Citrate 150 mg daily (from 2nd till 6th day of cycle) together with Ubiquinol starting from 2nd day till day of hCG triggering in a dose of 100 mg orally once daily. In group B, hMG was given from 2nd day of the cycle in a dose ranging from 75 to 225 IU. Serial transvaginal ultrasonography was done starting on cycle day 8 and continued till size of leading follicle reaches 18 mm or more then ovulation triggering was done. Thereafter, patients were advised for a timed intercourse (TI) after 36 hours. A blood sample was withdrawn seven days after hCG triggering, for measurement of serum progesterone. If the Patient presented with a missed period for one week, a serum sample was sent for β-hCG.

Results

There were no statistically significant differences (P > 0.05) between studied groups regarding; number of cases reaching mature follicular size, number of stimulated cycles, endometrial thickness on the day of hCG triggering, mid-luteal serum progesterone, positive serum pregnancy test and clinical pregnancy rate.

Conclusions

Addition of Ubiquinol to Clomiphene Citrate improved ovarian responsiveness in Clomiphene Citrate resistant patients with results comparable to conventional hMG stimulation protocol.

Published: August 2021

Background

Estimation of gestational age plays a pivotal role in day to day clinical practice for appropriate management of newborn. The trans-cerebellar diameter can predict gestational age in cases of variations of fetal head shape such as dolichocephaly and brachycephaly or even when fetus is in posterior position. Trans-cerebellar diameter (TCD) may be useful in gestational age estimation.

Aim and methodology

To determine the accuracy of trans-cerebellar diameter in the estimation of gestational age of fetus and comparing the conventional parameters like head circumference, biparietal diameter, abdominal circumference and femur length in the measurement of gestational age. This is a prospective, cross-sectional analytical study done in the Radiology Department in those patients who were referred to the department for a routine antenatal ultra-sonogram checkup.

Results

Comparison of trans-cerebellar diameter with gestational age derived from last menstrual period indicates that there is a linear relationship throughout the gestational ages. There is a strong correlation of trans-cerebellar diameter with other conventional parameters namely biparietal diameter, femur length and abdominal circumference of which Femur length correlates well with the trans-cerebellar diameter. Correlation of transcerebellar diameter with gestational age shows a R2 of 0.995 (p value < 0.001).

Conclusion

Trans-cerebellar diameter is best in estimation of gestational age when compared to biparietal diameter, femur length and abdominal circumference. The regression formula derived from trans-cerebellar diameter measurement can be applied to determine the gestational age of fetus.

High-speed visible light communication (VLC), as a cutting-edge supplementary solution in 6G to traditional radio-frequency communication, is expected to address the tension between continuously increased demand of capacity and currently limited supply of radio-frequency spectrum resource. The main driver behind the high-speed VLC is the presence of light emitting diode (LED) which not only offers energy-efficient lighting, but also provides a cost-efficient alternative to the VLC transmitter with superior modulation potential. Particularly, the InGaN/GaN LED grown on Si substrate is a promising VLC transmitter to simultaneously realize effective communication and illumination by virtue of beyond 10-Gbps communication capacity and Watt-level output optical power. In previous parameter optimization of Si-substrate LED, the superlattice interlayer (SL), especially its period number, is reported to be the key factor to improve the lighting performance by enhancing the wall-plug efficiency, but few efforts were made to investigate the influence of SLs on VLC performance. Therefore, to optimize the VLC performance of Si-substrate LEDs, we for the first time investigated the impact of the SL period number on VLC system through experiments and theoretical derivation. The results show that more SL period number is related to higher signal-to-noise ratio (SNR) via improving the wall-plug efficiency. In addition, by using Levin-Campello bit and power loading technology, we achieved a record-breaking data rate of 3.37 Gbps over 1.2-m free-space VLC link under given optimal SL period number, which, to the best of our knowledge, is the highest data rate for a Si-substrate LED-based VLC system.
Estrogen Receptor ß in Cancer: To ß(e) or not to ß(e)?
Authors: Hwang Nicole M , Stabile Laura P
Published: August 2021

Estrogen receptors (ERs) are known to play an important role in the proper development of estrogen-sensitive organs, as well as in the development and progression of various types of cancer. ERα, the first ER to be discovered, has been the focus of most cancer research, especially in the context of breast cancer. However, ERβ expression also plays a significant role in cancer pathophysiology, notably its seemingly protective nature and loss of expression with oncogenesis and progression. Although ERβ exhibits antitumor activity in breast, ovarian, and prostate cancer, its expression is associated with disease progression and worse prognosis in lung cancer. The function of ERβ is complicated by the presence of multiple isoforms and single nucleotide polymorphisms, in addition to tissue-specific functions. This mini-review explores current literature on ERβ and its mechanism of action and clinical implications in breast, ovarian, prostate, and lung cancer.

Objetivo: Relacionar as condições sociodemográficas, epidemiológicas e clínicas à ocorrência de casos graves de varicela. Métodos: Trata-se de um estudo transversal e analítico, tendo como fonte de dados prontuários de pacientes internados entre os anos de 2009 a 2018 no Hospital São José de doenças infecciosas (HSJ). Todas as variáveis selecionadas foram analisadas pelo programa Stata versão 15.1 e relacionadas com a presença de complicação, de forma a descobrir os fatores associados. Resultado: De um total de 302 prontuários, 54,3% eram do sexo masculino com idade mediana de 8 anos. A presença de complicação ocorreu em 82,4%, sendo complicações cutâneas as mais relatadas (65,4%). Das internações, 2,3% foram a óbito. A escolha da terapêutica com uso de antivirais associados a antibióticos (RP: 0,44; IC95%: 0,33 – 0,59 p=0,00) e alterações no exame de raios x de tórax (RP: 1,37; IC95%: 1,13 – 1,66; p=0,01) foram significativamente associados à gravidade do quadro de infecção por varicela. Conclusão: A varicela não deve ser considera uma doença inofensiva devido aos inúmeros tipos de complicações que podem associar-se à doença, causando internamento hospitalar e, em alguns casos, necessidade de tratamento intensivo. Os fatores associados foram a terapêutica utilizada, reduzindo a gravidade, e alteracoes no raio-x, aumentando a gravidade do caso.

Background: Interventions delivered in schools have been found to be effective in improving knowledge of antibiotics and antimicrobial resistance (AMR) among school-aged children, particularly those in high-income countries, but the evidence is largely lacking in low- and middle-income countries. This study aimed to design, implement and assess storytelling and picture drawing as engagement approaches for improving knowledge, attitudes and beliefs about antibiotics and AMR among schoolchildren in Ghana.

Methods: Two schools with a total population of 375 schoolchildren ages 11-15 years in Tema, a city in Ghana, participated in public engagement interventions involving storytelling in one school and picture drawing in another school. The interventions included eight weeks of engagement led by science teachers and a competition held in each school. For quantitative outcome-based evaluation, some schoolchildren were randomly sampled in each school. Purposive sampling was also used to select some schoolchildren in each school for qualitative outcome-based evaluation. Respondents completed identical knowledge, attitudes and beliefs questionnaires and were interviewed at two time points (before and at most a week) after key interventions to assess changes in antibiotics and AMR knowledge, attitudes and beliefs.

Results: Picture drawing had more significant effects (both positive and negative) on schoolchildren’s AMR knowledge, attitudes and beliefs, whereas storytelling had a negative effect on children’s AMR knowledge and no significant impact on beliefs and attitudes.

Conclusions: Our project’s findings suggest that public engagement interventions that use picture drawing and storytelling may influence the knowledge, attitudes and beliefs of schoolchildren regarding antibiotic misuse and AMR. However, modifications are required to make them more effective. These include making the storytelling effective by turning it into drama or plays.

Published: August 2021

Background:  This study assesses the behavioural responses to SARS-CoV-2 antibody test results as part of the REal-time Assessment of Community Transmission-2 (REACT-2) research programme, a large community-based surveillance study of antibody prevalence in England.

Methods: A follow-up survey was conducted six weeks after the SARS-CoV-2 antibody test. The follow-up survey included 4500 people with a positive result and 4039 with a negative result. Reported changes in behaviour were assessed using difference-in-differences models. A nested interview study was conducted with 40 people to explore how they thought through their behavioural decisions.

Results: While respondents reduced their protective behaviours over the six weeks, we did not find evidence that positive test results changed participant behaviour trajectories in relation to the number of contacts the respondents had, for leaving the house to go to work, or for leaving the house to socialise in a personal place. The qualitative findings supported these results. Most people did not think that they had changed their behaviours because of their test results, however they did allude to some changes in their attitudes and perceptions around risk, susceptibility, and potential severity of symptoms.

Conclusions: We found limited evidence that knowing your antibody status leads to behaviour change in the context of a research study. While this finding should not be generalised to widespread self-testing in other contexts, it is reassuring given the importance of large prevalence studies, and the practicalities of doing these at scale using self-testing with lateral flow immunoassay (LFIA).
La dimensión temporal de la Befindlichkeit y la experiencia afectiva de la Zeitlichkeit en Sein und Zeit.
Authors: Ballester Corres Roberto
Published: August 2021

A través de la analítica existenciaria de Sein und Zeit, se busca establecer, mediante el análisis de la Befindlichkeit en tanto que modo esencial de apertura del Dasein, la cooriginariedad entre Verstehen y Befindlichkeit, así como prestar una especial atención a la angustia (Angst), y la posibilidad de pensar una experiencia afectiva -como apertura directa y preteórica- de la Zeitlichkeit, el sentido temporal del ser del Dasein. Para ello, será necesario analizar tanto la dimensión temporal de la Befindlichkeit, como el papel fundamental de la angustia en su hacer patente la muerte, el cuidado y, con ello, la resolución precursora del Dasein. Así, alcanzaremos a ver cómo la Zeitlichkeit sólo es abierta, en el proyecto propio de Sein und Zeit, bajo la forma de una experiencia fundamental de carácter afectivo, esto es, mediante la Grundbefindlichkeit de la angustia
Una lectura de El guardador de rebaños a la luz del “habla poética” de Ser y tiempo.
Authors: Provinciatto Luís Gabriel
Published: August 2021

El § 34 de Ser y tiempo apunta a el “habla poética” como modo explícito de comunicación de las posibilidades existenciarias, manifestando el ser-ahí en su singularidad. El lenguaje, cuyo fundamento es el “habla” (Rede), articula, por tanto, el “encontrarse” (Befindlichkeit) y el “comprender” (Verstehen). Esto que se manifiesta por el lenguaje no es, al principio, concepto -obra de un ejercicio reflexivo-, sino sentido -proveniente de una experiencia fáctica. El “habla poética” caracteriza, así, el modo hermenéutico de articulación y construcción del lenguaje debidamente encontrada. Esto permite leer El guardador de rebaños de Alberto Caeiro, heterónimo de Fernando Pessoa, a partir del “habla poética”, notando que en el poema se articula el encontrarse, el comprender y el habla.
O USO DO QRCODE COMO FERRAMENTA PARA O ENSINO DE BOTÂNICA EM ESPAÇO NÃO FORMAL DE EDUCAÇÃO

Published: August 2021

Em pleno século XXI ainda nos deparamos com métodos de ensino centralizado somente no saber do professor e na condição de alunos passivos em uma educação dita como bancário. Como forma de superação e ressignificação do ensino, o uso de tecnologias e de espaços urbanos ditos não formais podem ser condições necessárias de superação deste modelo tradicional. Com o objetivo de contribuir com o ensino e a aprendizagem de Botânica se implantou em 2017, uma trilha “ecológica” na Praça Dom Pedro II (Parcão), no município de Uruguaiana, tendo como ferramenta de apoio o uso de QRCode para apresentar as características morfológicas e fenotípicas as árvores demarcadas na trilha e com isso oferecer aos alunos da educação básica de Uruguaiana-RS uma nova possibilidade de ensino e aprendizagem de Botânica. Os resultados obtidos com as atividades demonstram que a praça ainda é pouco explorada como espaço social e educacional, que os alunos conhecem pouco da flora urbana e que a atividade com o uso do QRCode provocou interesse, porém o processo poderia ser melhor aproveitado se o sinal público de internet chegasse com maior intensidade ao local.

Published: August 2021

O artigo discute a formação de professores para atuar com alunos com deficiência intelectual e a importância da formação de conceitos para a aprendizagem dentro da perspectiva histórico-cultural de Vigotski. Para tanto, conta com os dados de três dissertações de mestrado desenvolvidas no projeto de pesquisa “A escolarização de alunos com deficiência intelectual: políticas públicas, processos cognitivos e avaliação da aprendizagem”, com apoio financeiro do Programa Observatório da Educação da CAPES, desenvolvido na região da Baixada Fluminense/RJ. Metodologicamente, as pesquisas de campo foram de cunho qualitativo, estudo de caso e pesquisa-ação colaborativa. Entre os principais resultados, evidenciamos as dificuldades enfrentadas pelos professores em sua prática pedagógica em fornecer subsídios para que os alunos com deficiência intelectual se apropriem dos conhecimentos científicos no ambiente escolar. Contudo, os dados também evidenciaram possibilidades para que esses alunos tenham acesso aos conhecimentos historicamente construídos e uma delas é a formação continuada de professores baseada na perspectiva histórico-cultural.
ENTRE A MEMORIZAÇÃO E A INTERAÇÃO: A CONSTRUÇÃO DO PERFIL DOS ESTUDANTES DE ENSINO MÉDIO
Authors: Achterberg Guilherme Baumann , Centa Fernanda Gall , Terrazzan Eduardo Adolfo
Published: August 2021

Neste trabalho, é apresentado uma pesquisa sobre as condutas dos estudantes no que se refere à situações escolares de aprendizagens, com base no conceito de atitudes de Coll et al (2000) e Ajzen e Cote (2008) e também por meio dos estilos de aprendizagem, com base em Huizar (2009). A pesquisa tem caráter empírico, qualitativo e responde a seguinte questão de pesquisa: Quais as principais condutas que os estudantes manifestam em relação a situações de aprendizagem? Os resultados são apresentados em duas categorias que são construídas a partir das informações coletadas com estudantes do ensino médio. A análise ocorreu com base na Teoria Fundamentada nos Dados, aqui adaptada ao nosso contexto de pesquisa (TAROZZI, 2011). A memorização junto da realização de exercícios, o receio de errar e a preferência por interações foram os elementos que mais emergiram dos discursos, apontando para a necessidade da organização de aulas de forma articulada aos perfis dos estudantes. Conclui-se também que as condutas dos estudantes variam em função de outros elementos além de aspectos da personalidade, como por exemplo os componentes curriculares e os conteúdos abordados nas aulas.

A la suite du tournant culturel, l'approche culturelle se focalise sur les processus spatiaux dans lesquels la culture est impliquée. Le champ de la géographie culturelle s'en trouve élargi et approfondi. (i) La culture est modelée par les modes de transmission qui assurent son transfert d'une génération à l'autre et donnent plus ou moins de place aux savoir-faire et aux connaissances (à l'intelligence donc) et à l'émotivité et à l'imagination (aux imaginaires donc). (ii) Elle est également modelée par les débats et confrontations d'opinion, la genèse d'identités, les jeux d'imitation et de distinction auxquels elle donne lieu, les conflits et les dynamiques de civilisation ou de déclin qu'ils entrainent. (iii) La culture se combine à d'autres processus lorsqu'elle met en jeu la matière et le vivant, produit des artefacts, se confronte à la nature, s'applique au corps humain, prend en compte le jeu des sens et façonne des paysages. (iv) Elle contribue à la mise en scène de la vie sociale. Sous sa forme actuelle, la géographie culturelle complète par une approche socio-culturelle les approches socio-économiques et socio-politiques qui l'avaient précédée.

(I)MOBILIDADE E TÁTICAS ESPACIAIS NO QUOTIDIANO DE PESSOAS EM SITUAÇÃO DE SEM TETO: O CASO DO PORTO, PORTUGAL
Authors: Sarmento João , Leão Jorge
Published: August 2021

O mobility turn nas ciências sociais e humanas, recentrou o movimento como dimensão fundamental para a vida. Paradoxalmente, embora em abstrato pessoas em situação de sem teto tenham autonomia de uma localização espacial fixa para moradia, no concreto elas apresentam grandes dificuldades de movimento, e uma dificuldade em tirar partido dos benefícios de viver em cidades. Este artigo analisa a espacialidade de pessoas em situação de sem teto na cidade do Porto, Portugal. A pesquisa partiu de informação recolhida junto de prestadores de serviços que trabalham no terreno, da observação detalhada de um conjunto de ruas no centro da cidade, e de várias conversas com um conjunto de pessoas em situação de sem teto. São apontados cinco argumentos principais: as pessoas em situação de sem teto (i) têm uma grande imobilidade espacial; (ii) moram numa área muito confinada da cidade; (iii) têm rotinas espaciais específicas que governam rigidamente o seu quotidiano; (iv) têm rotinas espaciais principalmente ditadas pela lógica dominante dos "fornecedores de sopa"; (v) têm uma agência, por meio da qual estabelecem uma miríade de laços sociais baseados na confiança e na amizade.
USANDO O LUGAR PARA COMPREENDER O MUNDO DA VIDA: O EXEMPLO DO ROMANCISTA BRITÂNICO PENELOPE LIVELY EM SPIDERWEB
Authors: Seamon David
Published: August 2021

Este artigo busca esclarecer o conceito fenomenológico de mundo da vida por meio dos temas geográficos lugar, experiência de lugar e sentido de lugar. De modo mais simples, mundo da vida se refere à experiências consideradas, por pessoas ou grupos, como dadas a priori e, portanto, não visadas. Um objetivo da pesquisa fenomenológica é examinar o mundo da vida diretamente e, com isso, identificar e esclarecer aspectos da vida humana não visados. Então, eles podem ser entendidos de modo teórico e prático. Este trabalho discute alguns princípios da fenomenologia e, então, aponta capitulações de lugar para esclarecer alguns aspectos sociais, ambientais e geográficos do mundo da vida. Para concluir essa discussão, o artigo considera a evidência descritiva da escritora britânica Penelope Lively e sua obra Spiderweb, um romance de 1990 que descreve as motivações de um estrangeiro para habitar um lugar – uma vila fictícia dos dias atuais no Sudoeste Britânico do Condado de Somerset.

Published: August 2021

O Brasil se apresenta enquanto um país que não promove a existência de pessoas de LGBT+. O trato dispensado a discriminação por orientação sexual e por identidade de gênero tem sido irrisório em comparação a violência que pessoas fora da heteronormatividade tem sofrido em suas vidas cotidianas. Este processo de violência leva a injustiça espacial e a movimentos organizados de resistência. A Parada do Orgulho LGBT é a mais importante ação em busca de visibilidade. A cidade do Rio de Janeiro apresenta uma multiplicidade de Paradas. O objetivo deste trabalho é entender o que leva a essa articulação no espaço urbano da cidade. Estabeleceu-se o ano de 2017 como sendo o marco temporal do trabalho em função da ascensão do Bispo Marcelo Crivella ao comando da cidade. Percebeu-se diferentes articulações globais locais na promoção da visibilidade da causa LGBT+ na cidade do Rio de Janeiro.
FENOMENOLOGIA DA DISTÂNCIA (E DE SUAS CONTRADIÇÕES) EM TEMPOS DE PANDEMIA
Authors: Serpa Angelo
Published: August 2021

Pretende-se com este ensaio problematizar a noção de distância para a Geografia, em um momento de pandemia de COVID 19, que trouxe para a ordem do dia medidas de isolamento e distanciamento social para o controle da disseminação da doença nas cidades do Brasil e do Mundo. Assim, questiona-se, em um primeiro momento, a possibilidade de uma fenomenologia da distância, como uma maneira de problematizar esta noção como categoria e conceito no/para o fazer geográfico e, em um segundo momento, com base em critérios socioculturais, busca-se elaborar uma dialética da distância para o desvelar das contradições advindas da contraposição de seus aspectos materiais e imateriais. Com base em autores como Merleau-Ponty, Heidegger e Bourdieu, conclui-se que a noção de distância apresenta um efetivo potencial organizacional quando a analisamos sob um viés epistemológico e teórico, devendo-se articular diversidade e desigualdade para revelar os paradoxos e contradições engendrados pela distância em diferentes contextos e situações de cunho cultural e social.
NAS PÁGINAS DO MULHERIO (1981-1988): UM PANORAMA SOBRE A CRÍTICA LITERÁRIA FEMINISTA E A QUESTÃO HISTORIOGRÁFICA
Authors: Da Rocha Virgínea Novack Santos , Morais Jaísa Girardi
Published: August 2021

Partindo-se da análise das 41 edições do jornal Mulherio, posterior Nexo - Feminismo, informação e cultura,  que circulou entre 1981 e 1989, buscou-se perceber o modo como o periódico feminista aborda questões sobre literatura produzidas por mulheres e a suas participações na historiografia literária, levando-se em consideração os diversos processos de inferiorização, silenciamento, exclusão e a apagamentos que escritoras mulheres e suas literaturas são submetidas pela crítica hegemônica. Nesse sentido, foi possível perceber que há no jornal um grande interesse na recuperação de escritoras do passado e divulgação de escritoras do presente da publicação, além do interesse em discutir temas próprios à “escrita feminina”, isto é, uma crítica literária própria à literatura de mulheres. Dessa forma, a partir desses dois movimentos do próprio Mulherio foi possível recuperar e analisar situações contextuais de sua exclusão escritoras relativamente grande circulação ao seu tempo, mas ainda assim excluídas do cânone oficial das histórias literárias: Cassandra Rios, Maria Elisabete Lima Mota e Dinorath do Valle.

Published: August 2021

Highlights

We present an Internet of Things (IoT) platform to monitor site-specific weather conditions at the farm level.

We built a distributed mesh network of sensor nodes using open-source and open-hardware tools.

We tested different communication range scenarios and installation setups.

Emerging IoT technologies are susceptible to failure but have the potential to improve site-specific data collection.

Abstract
. This article describes the design, deployment, and evaluation of an Internet of Things (IoT) platform to monitor site-specific weather conditions at the farm level using wireless sensor networks (WSN). A distributed mesh network of sensor nodes was developed using open-source software and hardware tools to monitor temperature and relative humidity in-field environmental conditions. The IoT prototype was tested at the University of Florida’s research farm. Data from the sensor nodes were compared to a Florida Automated Weather Network weather station. The results of this study will contribute to the implementation of site-specific collection tools and with site-specific decision management in specialty crop production systems. A significant advantage of IoT and WSN over a standalone weather station is the capability to monitor micro-weather conditions that may lead to site-specific management operations.

Separation of Empty Kernels Using the Physical Properties of Short-Grain Rough Rice
Authors: Lee Hyo-Jai , Kim Oui-Woong , Chang Ji Hong , Kim Hoon
Published: August 2021

Highlights

Physical properties of whole rough rice and empty kernels of five short-grain rice varieties were measured.

Geometric traits of kernels could not be used for the separation of empty kernels from whole kernels.

Separation of kernels can be achieved based on weight difference between whole and empty kernels.

Air velocity in pre-cleaners should be set between the terminal velocities of whole and empty kernels.

Abstract
. The key factors required to separate empty kernels (EKs) from whole kernels (WKs) were investigated in rough rice varieties. The geometric properties and 1000-grain weight of rough rice WKs and EKs of five varieties of short-grain rice with varying moisture content were measured. The terminal velocities for floating and dropping of WKs and EKs were tested in a vertical air column to identify the aerodynamic separation characteristics. The separation of EKs from WKs based on kernel geometric characteristics was not possible because of insignificant differences between WKs and EKs in terms of length, width, roundness, and other geometric characteristics. The 1000-grain weight of WKs and EKs ranged from 23.7 to 29.2 g and from 3.9 to 8.5 g, respectively. Linear regression equations were used to determine the relationship between terminal velocity and moisture content in both floating and dropping phase. The allowable floating and dropping terminal velocity range for separating WKs and EKs ranged from 5.0 to 7.6 m s-1 and from 2.1 to 4.1 m s-1, respectively. Moisture content, and especially, kernel type and terminal velocity type had significant effects on the terminal velocity.

Authors: Ai Pengrui , Ma Yingjie , Hai Ying
Published: August 2021

Highlights

Moderate water deficit will help reduce agricultural investment.

Application of potassium fertilizer can alleviate the effect of water deficit on fruit trees.

Reasonable ratio of water and fertilizer is helpful to improve economic benefits.

Abstract
. The jujube planting industry is a key agricultural industry in Xinjiang, China. With an arid climate and limited water resources, Xinjiang must implement more efficient water-saving irrigation systems to guarantee the sustainable development of jujube planting industry. A two-factor, three-level test was adopted to explore how regulated deficit irrigation and different potassium fertilizer levels affected the growth and yield of jujube under drip irrigation. The results of analysis of variance showed that water deficit significantly affected photosynthetic characteristics, growth parameters, evapotranspiration, and yield. The effect of K-application level was focused on fruit volume and yield. However, when the ratio of water to fertilizer is unbalanced (150% K-application + severe water deficit), the growth of jujube trees be inhibited, and the fruit volume and economic benefits reduced by 7% and 11%, respectively. Means comparison indicated that growth parameters, evaporation, and yield under minor water deficit was lower than that under the adequate irrigation by 7%, 13%, and 6%, respectively; and economic performance was higher by 12%. Severe water deficit reduced growth parameters and economic benefits by 33% and 55%, respectively. Thus, minor water deficit irrigation significantly inhibited luxury transpiration and growth redundancy, improved water-use efficiency and increased economic performance. Severer water deficit may damage trees and negatively affect the jujube industry. With economic benefit analysis, 150% K-application with adequate irrigation and minor water deficit, 100% K-application with adequate irrigation and minor water deficit, 50% K-application with minor water deficit all achieve high economic benefits (14074~17261 RmB ha-1). However, when taking water restrictions, the environmental and economic costs of fertilizer, and the long-term effects of tree development into account, application of 100% K-application with minor water deficit (irrigation, 75% ETc; fertilizer, 200 kg ha-1 compound fertilizer+360 kg ha-1 potassium fertilizer) is recommended.

“What lies behind us & what lies ahead of us are tiny matters to what lies within us!”
– Ralph Waldo Emerson

Many clinicians across the world aspire to come to United Kingdom and work in NHS. Initial months could be challenging to work in completely new healthcare system. With some help from good colleagues, transition for overseas doctors can be less overwhelming.
As an International Medical Graduate (IMG), there are several options for career progression in UK. Many doctors enter in the UK formal training program, however, Certificate of Eligibility for Specialist Registration (CESR) is an alternative pathway to achieve CCT. The CESR route could be helpful for clinicians trained in countries outside the UK or European Union as their training from their country of origin might not be recognized equivalent to CCT by General Medical Council (GMC). After obtaining CESR certification, your name is added to specialist register which is a absolute necessity to obtain a substantive consultant position in UK.
There is ever increasing requirement for doctors in the UK due to staff shortages and now Covid-19 pandemic has pushed many trusts against the wall to fill these positions. Apart from recruiting overseas doctors, CESR certification has proven to be helpful in filling up these positions. The GMC made some favorable changes in the CESR process in recent years which has encouraged and many career grade/staff grade doctors to progress. On other hand, trainees who fail to obtain training post after several attempts are opting for CESR as an alternative route to progress. Annual statistics published by the GMC indicate that there is rising trend in number of applications for CESR certification in all specialties. There is a gradual change in the perception of CESR as an equally attractive route for career progression.
However, there are many unknowns in this pathway as this has been a path less travelled. There is a general perception that CESR certification is difficult t

Background

Selective fetal restriction growth (sFGR) is one of the common diseases of monochorionic diamniotic (MCDA) twin pregnancies, resulting in many adverse outcomes. At present, second trimester ultrasonography is widely used in the prenatal diagnosis of sFGR, but the diagnostic effectiveness is still uncertain. The aim of this study is to assess the diagnostic accuracy of second trimester Doppler ultrasound measurements for sFGR.

Methods

A retrospective study included 280 pregnant women (118 with and 162 without sFGR) with MCDA pregnancies was conducted in the fetal medicine center from Leiden University Medical Center from January 2008 to December 2013. The women participating had already undergone an ultrasound examination in the second trimester. The postnatal criteria of sFGR was a single birth weight (BW) < 3 rd percentile in a twin, or birth weight discordance (BWD)≥25% between two twins, while the BW of the smaller twin < 10th percentile. Early prenatal diagnosis of sFGR was defined as a single EFW < 3 rd percentile in a twin, or at least 2 of the following 4 parameters must be met (fetal weight of one fetus < 10th percentile, AC of one fetus <10th percentile, EFW discordance≥25%, UA pulsatility index (PI) of the smaller fetus > 95th percentile). According to the diagnosis of sFGR after birth, we evaluate diagnostic effectiveness of Doppler ultrasound in the second trimester for sFGR.

Results

Of these 280 participants, the mean age was 32.06 ± 4.76 years. About 43.9% of pregnant women were primiparas. The ability of second trimester Doppler ultrasound to accurately diagnosed sFGR is 75.4%, missed diagnosis rate and the misdiagnosis rate were 24.6% and 10.5% respectively. The ROC curve indicated that the combination of AC discordance, EFW discordance, and small fetal UA blood flow was the best diagnostic indicator of sFGR in MCDA pregnancy with the AUC was 0.882 (95%CI, 0.839–0.926).

Conclusions

Second trimester Doppler and ultrasound measurements is an effective method for early prenatal diagnosis of sFGR. The combined indicator of AC discordance, EFW discordance, and the small fetal UA blood flow reaches highest diagnostic value.

Torque Teno Virus (TTV) is a small, non-enveloped, single-stranded and circular DNA virus that infects the majority of the population worldwide. Increased levels of plasma TTV viral load have been observed in various situations of immune deficiency or dysregulation, and several studies have suggested that TTV levels may be inversely correlated with immune competence. The measurement of TTV viremia by qPCR has been proposed as a potential biomarker for the follow-up of functional immune competence in immunosuppressed individuals, particularly hematopoietic stem cell transplant recipients. We hypothesized that TTV viral load could be used as a prognostic marker of immune checkpoint inhibitor (ICI) efficacy, and therefore investigated the TTV viral load in melanoma patients treated with nivolumab or pembrolizumab before and after 6 months of treatment. In the present study, TTV viral load was not different in melanoma patients before anti-PD-1 introduction compared to healthy volunteers, was not modified by ICI treatment and did not allowed to distinguish patients with treatment-sensitive tumor from patients with treatment-resistant tumor.
Opening the wound: Receptions and readings of Inxeba in South Africa
Authors: Levine Susan
Published: August 2021

This reading of Inxeba (2017) foregrounds the relationship between the #RhodesMustFall and #FeesMustFall movements in South Africa with the theme of wounding as an enduring social affliction in a country caught up in the midst of redefining itself after apartheid. Overtly narrated in the telling of Inxeba (2017) is the striking, amplified distinction between tradition and modernity among isiXhosa. Indeed, the polarized reception of the film among South African audiences shone a light on the slow burn of this most enduring trope. At universities across the country, Black students called for an end to the symbols of imperialist and colonialist White domination, as well as the desire to decolonize higher education by redressing Eurocentric canons of knowledge production. On the heels of the #Fallist movements, a White director makes a film about Xhosa initiation, and folds into this story a tale of homoerotic love. Notwithstanding the film’s official entry for best foreign language film at the Oscars, multiple forms of wounding came quick and heated upon the showcasing of the film’s trailer on social media.

The role of place and identity as core contributing success factors in Jayan Moodley’s Keeping up with the Kandasamys and Kandasamys: The Wedding
Authors: Moodley Sogen , Govender Arushani
Published: August 2021

Keeping up with the Kandasamys(), a family comedy co-written and directed by Jayan Moodley, was the first cinematic feature to be set in the post-apartheid Indian township of Chatsworth, Durban and generated R16.3 million at the box office. The film delves into the matriarchal rivalry of neighbouring families while showcasing the unique Chatsworth subculture. This box office success prompted the release of the sequelKandasamys: The Wedding(), which broke its own sales record, earning R18.9 million. As filmmakers who were intimately involved in the production of the sequel, and who engaged with viewers and community members, we provide a critical analysis, reflecting on why the films attracted large audiences and galvanized an outburst of fandom. This article postulates that Indian South African audiences identified with the authentic portrayal of the nuances of every-day life in Chatsworth, resulting in feelings of visibility and nostalgia. In attempting to explain the phenomenal support from these audiences, the authors examine theories of place identity and literature on Indian South African identity, inferring that the intersection of place, and the representation of Indian South Africans in the features, is significant to the films’ success.

Published: August 2021

Background and Aim: Zearalenone (ZEA) is a mycotoxin from the fungus Fusarium. ZEA can adopt a similar configuration to 17β-estradiol and other natural estrogens. Problems in the reproductive function of humans and animals have been reported for ZEA and its metabolites. This study aimed to determine ZEA in raw milk produced in representative milk production areas in Ecuador.

Materials and Methods: A total of 209 samples were obtained in April and November 2019 (rainy season) and June and August 2019 (dry season). A competitive enzyme-linked immunosorbent assay technique was used to detect ZEA concentrations.

Results: ZEA was determined in 99.5% (208 of 209) of the samples; however, all samples were below the maximum limits allowed (0.03-1 mg/L) in food for direct human consumption according to the Food and Agriculture Organization and European legislations. The mean (range) concentration was 0.0015 (0-0.0102) mg/L. The results did not vary significantly (p≥0.05) by cantons, provinces, weather, climate regions, types of producers, and production systems according to Wilcoxon and Kruskal–Wallis non-parametric tests. There were significant differences only between the months under study (p≤0.05).

Conclusion: ZEA in raw milk from Ecuador does not represent a threat to public health. However, it is recommended to continue analyzing ZEA due to its presence in milk. It could also be present with other mycotoxins that cause harmful synergistic and additive effects to consumers.
