Examining the Reproductive Rights in the Wake of COVID-19 Pandemic in Nigeria
Authors: Nnawulezi Uche , Adeuti Bosede Remilekun
Published: February 2021

The prospect of achieving sustainable reproductive rights protection in the wake of the COVID-19 pandemic in Nigeria has remained an intractable problem. To identify and recognize reproductive rights, it is necessary to comprehend that reproductive right embraces certain human rights recognized in national and international laws, including international human rights’ documents. This paper examines the existing Nigeria laws on reproductive and health rights and ascertains the extent to which it has continually and predictably addressed the reproductive rights protection problem. There is a significant protection gap in the national human rights architecture. At the international level, among the poorer adolescent girls between the age of 15-19 years, it frequently results in early pregnancy and, of course, unsafe abortion. Thus, this gap relates in particular to questions on lack of access to family planning services. This paper argues that improvement of reproductive and sexual health goes far beyond the right to life and the right to health of women and girls. To guarantee Nigeria's reproductive rights, a more integral response to these critical human rights and development challenges can address Nigeria's protection gap. This paper adopts an analytical and qualitative approach by referring to existing pieces of literature achieved by the synthesis of ideas. This paper concludes that the adoption of a new approach to policies and programs on preventable maternal mortality and morbidity guarantees the right to attain the highest standard of sexual reproductive health in Nigeria.

How do Elementary Students Perceive the Utility of Dual-Language Children’s Books? An Exploratory Study in French Immersion
Authors: Thibeault Joël , Matheson Ian A.
Published: February 2021

Dual-language children’s books—books in which two languages cohabit—are currently gaining traction in the field of language education. Though some studies have zeroed in on the benefits of using them in classrooms, less is known about how learners perceive this tool’s utility for reading and language development. In this paper, we thus aim to explore how elementary students in French immersion perceive the utility of two types of dual-language books: translated, where all passages in French also appear in English, and integrated, where the story is told using an embedded discourse composed of both English and French.
Areia de britagem como alternativa à areia natural na confecção de concreto
Authors: Guimarães Cleidson , Gomes Mário Vinicius Aguiar
Published: February 2021

As fontes de areia natural, proveniente dos leitos dos rios, se encontram cada vez mais distantes dos centros de consumo, causando como consequência o aumento gradativo do seu custo ao longo dos anos. Redução das jazidas e burocracia para legalização ambiental também são fatores que impulsionam novas pesquisas relacionadas à substituição da areia natural como agregado miúdo pela indústria da construção civil. Por meio deste trabalho procura-se expor o estado da arte das pesquisas realizadas, por meio das plataformas Web of Science, Lens e Google Acadêmico, acerca de uma alternativa para a areia natural na fabricação do concreto, visando aprimorar a inserção dos agregados artificiais no mercado e suas técnicas de utilização. Estudos vêm mostrando os benefícios da utilização da areia de britagem no concreto como também o que vem dificultando o seu emprego. A forma angular de suas partículas e a quantidade de finos acaba por resultar no uso de mais água para atender a parâmetros de trabalhabilidade. Contudo, o aumento da resistência à compressão simples e melhoria de algumas das propriedades do concreto coloca a areia de britagem como uma grande promissora na indústria da construção civil.
Requalificação de rios urbanos no âmbito da renaturalização, da revitalização e da recuperação
Authors: Silva Juliana Caroline de Alencar da , Porto Monica Ferreira do Amaral
Published: February 2021

A requalificação de cursos d’água, principalmente em áreas urbanas, é um grande desafio para a manutenção e retomada dos serviços ecossistêmicos valiosos prestados por estas áreas, auxiliando no aumento da qualidade de vida da população. As intervenções, em cursos d’água, podem ser classificadas de diferentes formas, em função do grau de atuação em cada uma das frentes envolvidas no processo e no contexto em que o curso d’água está inserido. Neste estudo foi realizada uma revisão da literatura existente sobre o assunto a fim de encontrar qual definição utilizada para cada tipo de requalificação de cursos d’água, e obteve-se o uso predominante de 3 termos: a Renaturalização, a Revitalização e a Recuperação. A renaturalização se dedica ao retorno do sistema às condições naturais, ou às condições pré-desenvolvimento. Já revitalização se dedica à criação de uma nova condição de equilíbrio, diferente da condição natural, para o sistema para que este possa suportar diversos tipos de usos urbanos. Por fim a recuperação se dedica ao reestabelecimento das condições sanitárias do sistema, podendo ser vista como uma etapa intermediária da revitalização e da renaturalização. Diante das demandas existentes em cada uma das três técnicas, neste estudo é realizada a análise crítica da aplicabilidade de cada uma delas para o caso brasileiro.

Published: February 2021

A vida urbana vem sofrendo profundas mudanças em decorrência das perdas causadas pela pandemia de Covid 19, que segundo a OMS (Organização Mundial da Saúde) é uma disseminação mundial do novo coronavírus, colocando-nos diante de uma reflexão sobre os desafios para nosso futuro comum: Que modelo de planejamento urbano devemos construir, e como  as pessoas poderão se apropriar dos espaços públicos e das áreas verde da cidade de forma segura, inclusiva e com qualidade de vida nesse período durante e após pandemia? A pandemia declarada em 11/03/2020 pela OMS colocou em questão e ressaltou a importância das áreas verdes e dos espaços públicos urbanos, em contrapartida ao isolamento social a que todos ficamos submetidos, como a única “vacina” disponível para evitarmos a contaminação. Ao mesmo tempo, esse futuro incerto, nos remete a perguntas e incertezas sobre a maneira como enfrentar a crise climática, e fortalecer a sustentabilidade urbana e a qualidade de vida das pessoas em todo o planeta. A retrospectiva das pandemias que o mundo vem enfrentando, enfatiza a importância das áreas verdes na qualidade ambiental urbana das cidades, tendo como um dos principais elementos de preocupação a saúde das pessoas. Nesse sentido, será necessário propor mudanças no espaço físico e na forma de uso dos espaços públicos e das áreas verdes como forma de ressignificação da vida urbana.

Field research was done to evaluate the financial benefits of forest honeybee business conducted by the local community at Kameloh Baru Village, Taruna Village, and Tumbang Nusa Village in Central Kalimantan. These villages studied are known as a natural honeybee-producing center in Central Kalimantan. The local tribe gathers forest honeybee from Apis dorsata that have done for generations. The results revealed that the income of forest honeybee gathering people in 2015 amounted to IDR six to ten million once harvest. The owner of a tree of honeybee nest has five times higher income than harvesters. However, after a forest fire in 2015, revenues in 2016 and 2017 dropped dramatically to 25% of the previous year. The depletion of natural food resources is a leading factor in honeybee production decrease. On the other hand, the farmers do not have the initiative to cultivate the host trees and reserve natural food resources. Forest honeybee cannot be harvested regularly, although the market demand for forest honeybee is still tremendous. On the other hand, a proper technique of honeybee harvesting did not conduct so that the resulting honeybee quality decreases. Neverthenless, the local tribe can develop sustainable forest honeybee gathering based on their ecological knowledge as incentives for forest conservation.

Banjarmasin is dominated with the combination of land and river, which resulted many riverside areas in the city. These areas are functioned as settlements area, as well as commercial and public areas as the focus of the city’s development and the local’s daily activities. However, the rapid development in Banjarmasin still giving less attention to the development of green open spaces, despite the local connection with the river. Therefore, this research aimed to identify the local perception of green open space in the riverside areas of Banjarmasin through descriptive qualitative analysis. Questionnaires and observations in five study areas were done to obtain the local perception. The results show that the highest local perception index is for the  social aspects for 87,2 points and the lowest local perception index is the spatial planning aspects for 42,6 points. Banjarmasin needs to focus more on the spatial planning of green open spaces in riverside areas and enhancing the opportunity for locals to participate in any spatial planning process (participatory planning).

Teluk Pamukan is the closest fishing ground used by fishermen who live on the coast of Teluk Pamukan. Apart from fisheries, several other activities in the Teluk Pamukan area include industrial shipping or coal transportation traffic using barges, transportation of crude palm oil (CPO), and is an area for loading and unloading fertilizers and oil palm kernels by tankers. This activity has led to allegations of disturbance in the aquatic ecosystem in the form of a decrease in water quality, particularly in fishing areas. The decrease in water quality will certainly affect the status of water quality that is no longer by its designation so that it can cause social problems in the community. The purpose of this research was to identify the general characteristics of Teluk Pamukan, map the distribution patterns of water quality and the scale of water quality in Teluk Pamukan, and to analyze fishermen's perceptions of the decline in water quality. The sampling location was in the waters of Teluk Pamukan. The method used to determine the status of water quality was the Pollutant Index according to the opinion of Sumitomo and Nemerow (1970). The results obtained can be concluded that the environmental quality scale for each parameter varied from very bad to very good. However, the results of the pollutant index calculation at all stations were included in the Moderately Polluted category
International Supply Chains in APR
Authors: Sokolov V.
Published: February 2021

The article considers the problem of international supply chains in machinery-building. The meanings of appropriate terms are specified (outsourcing, international production sharing, vertical specialization). It is clarified (following D. Hummels et al.) the definition of vertical specialization as a structure of supply chain when a country is using imported inputs to produce goods for exports. It is emphasized that countries exporting raw materials usually show high share of vertical specialization-based trade in their exports but not in imports. Developed industrial countries (excluding Japan) usually show high content of vertical specialization-based trade in both exports and imports. Statistical analysis of the intra-industry labor division in the office, accounting and computing machinery of Asia and Pacific is made. In China and Japan most inputs consumed by office, accounting and computing machinery are of domestic origin. The larger share of intermediate production of the office, accounting and computing machinery, consumed by the same branch, in China is of domestic origin, too. It means that a queue of successive components of supply chains is placed on the territory of China. At the same time, what concerns the territory of Korea assembling industries are prevailing. In USA and Japan the branch is using as inputs mostly intermediate production of domestic origin. Still, a larger fraction of the intermediate production of the computer industry itself is imported. In the four from five countries reviewed (USA, Japan, Republic of Korea, Thailand) the imported intermediate production for computer industry used by the respective industry as inputs is larger than the domestic production. This proves high degree of internationalization of this industry in Asia and Pacific.
INTEGRATION Large-scale Modeling Framework of Direct Cellular Vehicle-to-all (C-V2X) Applications

Published: February 2021

The transportation system has evolved into a complex cyber-physical system with the introduction of wireless communication and the emergence of connected travelers and connected automated vehicles. Such applications create an urgent need to develop high-fidelity transportation modeling tools that capture the mutual interaction of the communication and transportation systems. This paper addresses this need by developing a high-fidelity, large-scale dynamic and integrated traffic and direct cellullar vehicle-to-vehicle and vehicle-to-infrastructure (collectively known as V2X) modeling tool. The unique contributions of this work are (1) we developed a scalable analytical communication model that captures packet movement at the millisecond level; (2) we coupled the communication and traffic simulation models in real-time to develop a fully integrated dynamic connected vehicle modeling tool; and (3) we developed scalable approaches that adjust the frequency of model coupling depending on the number of concurrent vehicles in the network. The proposed scalable modeling framework is demonstrated by running on the Los Angeles downtown network considering the morning peak hour traffic demand (145,000 vehicles), running faster than real-time on a regular personal computer (1.5 hours to run 1.86 hours of simulation time). Spatiotemporal estimates of packet delivery ratios for downtown Los Angeles are presented. This novel modeling framework provides a breakthrough in the development of urgently needed tools for large-scale testing of Direct C-V2X enabled applications.

Dorsal Medial Cuneiform Bony Outgrowth—Apophysis or Exostosis
Authors: Malige Ajith , Surrey Lea F. , Davidson Richard
Published: February 2021

Case:

Three female children (11-15 years) presented with painful dorsomedial medial cuneiform masses that did not improve after conservative treatment. Findings were consistent with a diagnosis of medial cuneiform apophysis. After surgical resection, no patients had recurrence, although one continued to have pain from a deep peroneal nerve sensory branch that was resected. One patient had an intramass physis identified.

Conclusion:

When surgically removing dorsomedial cuneiform masses, surgeons should decompress overlying sensory nerve branches, detach and subsequently repair muscular attachments, and remove the entire stump to prevent regrowth because some of these masses may be apophyses and not exostoses.

Upper extremity arteriogram revealed absent flow to the radial aspect of the finger and compromise of the ulnar digital artery distal to the proximal interphalangeal joint. After failing nonoperative management, she underwent periarterial sympathectomy with relief of symptoms.

Conclusion:

Repetitive trauma to a catcher's hand can result in vascular compromise. When nonoperative measures fail, surgical intervention may be successful. We describe successful treatment using sympathectomy. Surgeons should be able to diagnose this condition and understand treatment options.

Rivers finding their path through different hamlets, industries and residential etc. are the end receivers of liquid and solid waste. This plight of water bodies has been deteriorating the life of the river stretches and greatly impacting the quality of water. The identification of potentially polluted locations and timely action can help in restoring the water quality of the river stretches and improving the life of water body as well. The dynamics of river Ganga stretches has been modeled using Non-linear Autoregressive network with exogenous inputs (NARX) model spatially and temporally simultaneously. This method helps in developing one single model to understand all the stretches simultaneously which is not possible otherwise. The change in behavior of NARX model under consecutive and non-consecutive time period has also been studied using statistical methods and multi-step ahead predictions. The model developed in this study captures all the seasons together in one single model and has been used to predict BOD values at seven different locations for nine months ahead. The results highlight the performance ability of NARX model to understand future water quality changes of river Ganga stretch owing to continuous pollution adding to the river. The results predicted for 9 months ahead for year 2015 using two different models, a lower root mean square error (RMSE) as 0.026 and higher correlation coefficient ‘r’ as 0.992 was obtained for model with consecutive days while for other model with non-consecutive days the RMSE was 0.031 and r was 0.989. This information may provide some guidance to the policy makers and water managers to prepare and suggest the pollution mitigation measures for the life line of millions; River Ganga.
Performance analysis of Tunnel FET based Ring Oscillator using Sentaurus TCAD
Authors: Yadav Menka
Published: February 2021

A detailed Sentaurus TCAD simulation based study for Silicon Double Gate Tunnel Field Effect Transistor (Si-DG TFET) based Ring Oscillator (RO) is presented in this work. Two different ring oscillator topologies (simple RO and Negative Skewed Delay RO )are presented with two different structures for TFET device. The two structures are different in the source-drain extension regions widths. The extension region width variation effects are studied and presented for inverter and ring oscillator. A TFET based inverter is presented to show the changes in behavior due to variations in the drain extension region widths, which is later used for RO designs. The drain extension region width changes the drain extension region resistances which in turn is responsible for change in the corresponding device properties. RO simulation are used for calculating the delay. To further explore digital and analog applications transfer characteristics and noise margins of inverter are explored with power supplies variations. Better reliability for oscillation frequency is obtained using Negative Skewed Delay ring oscillator (NSD RO) topology. NSD RO is resulting in lesser jitter, more reliable frequency as compared to single-ended ring oscillator topology. By tuning the supply voltage of the device the ring oscillator frequency can be used for RF applications, thus it works like a voltage controlled oscillator (VCO).

Background: Thyroid cancer (TC) has inflicted huge threats to the health of mankind. Chlorophenols (CPs) were persistent organic pollutant and can lead to adverse effects in human health, especially in thyroid. However, epidemiological studies have revealed a rare and inconsistent relationship between internal exposure to CPs and TC risk. This study was designed to examine the association between urinary CPs and risk of TC in Chinese population.Methods: From June 2017 to September 2019, a total of 297 histologically confirmed TC cases were recruited. Age and gender matched controls were enrolled at the same time. Gas chromatography-mass spectrometry (GC-MS) was used to determine the levels of three CPs in urine. Conditional logistic regression models were adopted to assess the potential association. Restricted cubic spline function was used to explore the non-liner association.Results: After adjusting for confounding factors, multivariate analysis showed that, compared with the first quartile, the fourth quartile concentrations of 2,4-dichlorophenol (2,4-DCP), 2,4,6-trichlorophenol (2,4,6-TCP) and pentachlorophenol(PCP) were associated with TC risk [odds ratio (OR)2,4-DCP =2.28, 95%confidence interval (CI): 1.24-4.18; OR2,4,6-TCP =3.09, 95% CI: 1.66-5.77; ORPCP =3.30, 95% CI: 1.71-6.36, respectively]. When CPs were included in the multivariate model and restricted cubic spline function as continuous variables, presenting significant dose-response relationships. Meanwhile, whether in the TC group with tumor diameter > 1 cm or metastatic TC, the changes of 2,4,6 TCP and PCP concentrations were positively correlated with the risk of TC. Conclusions: Our study suggests that higher concentrations of urinary CPs are associated with increased TC risks. Moreover, 2,4,6-TCP and PCP have certain effects on the invasiveness of thyroid cancer. Targeted public health policies should be formulated to reduce the CPs pollution. These findings need further in-depth studies to confirm and relevant mechanism also needed to be clarified.

Background: This study aimed to investigate the biological functions of exosome in follicle microenvironment and illustrate the underlying mechanism about the different IVF outcomes among normal, diminished ovarian reserve (DOR) and aging female patients with the same biological ovarian age. Methods: Follicular fluid (FF) was collected from control(n=35), DOR(n=35), aging(n=35) who underwent IVF therapy in 2017 and 2018. Electron microscope and NanoSight were used to detect the exosomes morphology and concentration. Hormones levels and anti-Müllerian hormone (AMH) in the serum were detected by ELISA. Results: Serum FSH and FSH level of the DOR group and the aging group significantly increased, AFC was decreased compared to the control. Exosomes concentrations were significantly lower in DOR and aging as compared with control group and were also significantly lower in the aging group compared with the DOR group. Exosomes was negatively correlated with FSH and FSH/LH, exosomes was positively correlated with AMH. GDF9 and BMP15 were secreted by exosomes. Conclusions: Exosome was highly represented in human FF and are involved in maturation of follicle. The concentration of exosomes in FF can be an indicator of ovarian reserve. Oocytes may secrete exosomes.

Two-dimensional (2D) borophene is predicted as an ideal electrode material for lithium sulfur (Li-S) batteries because of low-density, metallic conductivity, high Li-ion surface mobility and strong interface bonding energy to polysulfide. But until now, 2D borophene-based Li-S batteries have not yet been achieved due to the absence of massive synthesis method. Herein, we developed a novel low-temperature liquid exfoliation (LTLE) method for scalable synthesis of single crystalline 2D few-layer β12-borophene sheets with a \(P\stackrel{-}{6}m2\) symmetry. The as-synthesized 2D sheets were used as the polysulfide immobilizers and electrocatalysts of Li-S batteries for the first time. The resulting Li-S cells employing borophene sheets delivered a strikingly high areal capacity of 5.2 mAh cm− 2 at a high sulfur loading of 7.8 mg cm− 2 with an ultralow capacity fading rate (0.039 % per cycle) in 1000 cycles, outperforming most of the Li-S batteries employing other 2D materials. Under the help of few-layer β12-borophene, their high-activity behaviors should be attributed to the significant enhancement of both the Li-ion’s surface migration and the adsorption energy for Li2Sn clusters based on density functional theory (DFT) models. Our research reveals great potential of 2D β12-borophene sheets in future high-performance Li-S batteries.
