Improving ALD-Al2O3 Surface Passivation of Si using Native SiOx
Authors: Getz Michael N. , Povoli Marco , Monakhov Eduard 
Published: October 2021

Abstract
Al2O3 has rapidly become the surface passivation material of choice for the n-type Si solar cells with p + emitter due to its high negative fixed charge, good long-term and thermal stability, and no parasitic absorption. In this study, the surface saturation current density, fixed charge, and interface state density is compared for Al2O3 grown on Si substrates where the native SiOx was not removed, with substrates where the SiOx was removed by hydrofluoric acid. The depositions are performed by atomic layer deposition at temperatures in the 150–300 ˚C range, using trimethylaluminium, H2O, and O3 as precursors. The samples where the native oxide was not removed achieve a higher level of surface passivation for every tested deposition temperature, with the sample deposited at 200 ˚C exhibiting a surface saturation current density of only 1.9 fA/cm2, a fixed charge of 4.2×1012 cm− 2, and a density of interface states of 9.8×109 cm− 2 ev− 1. Capacitance and conductance voltage characteristics reveal a strong correlation between the surface saturation current density and the density of interface states and fixed charges. It is also determined that the long-term stability of the surface passivation depends on the deposition temperature, with higher deposition temperatures resulting in improved long-term stability.

Abstract
BackgroundLimited studies have compared determinants of household knowledge of split and grouped mosquito larval source management (LSM) methods. Thus, we compared determinants of household knowledge of split and grouped mosquito LSM methods for malaria control in Malawi. MethodsA cross-sectional study was conducted among 479 households in Nthache, Mwanza district, Malawi. Household knowledge of mosquito LSM methods; draining stagnant water, larviciding, clean environment and clearing grass/bushes were assessed by using a validated structured household questionnaire administered to an adult household member. Chi-square test was used to compare the distribution of household knowledge of each of the split and grouped mosquito LSM methods. Multivariable logistic regression was used to examine factors associated with household knowledge of each of the split and grouped mosquito LSM methods. ResultsHousehold knowledge of draining stagnant water was lower than high-level knowledge of grouped mosquito LSM methods (32.9% versus 83.5%, p=0.000). Household knowledge of clearing grass/bushes was lower than high-level knowledge of grouped mosquito LSM methods (8.2% versus 77.7%, p=0.000). Household knowledge of clean environment was lower than high-level knowledge of grouped mosquito LSM methods (21.8% versus 63.8%, p=0.000). No significant differences were observed between knowledge of larviciding and high-level knowledge of grouped mosquito LSM methods (4.1% versus 5.8%, p=0.421). Respondents without education had 57% less the odds of having knowledge of draining stagnant water than those with primary education (AOR=0.43, 95% CI 0.26-0.69). Those from iron-roofed households and the widowed had three and more than four times the odds of having knowledge of larviciding than those from grass-thatched households and the married (AOR=3.03, 95% CI 1.26-7.29 and AOR=4.73, 95% CI 1.34-16.73), respectively. ConclusionsExcept for larviciding, household knowledge of grouped mosquito LSM methods was significantly higher than split methods. Policy for integrated vector management should address determinants of split mosquito LSM methods to improve household knowledge.

Abstract
Background

Salt iodization is the most cost-effective, safe and sustainable strategy to eliminate iodine deficiency disorders. It is especially damaging during pregnancy and in early child hood. Adding iodine to salt provides protection from brain damage due to iodine deficiency for whole populations. However, little was known about the availability of adequately iodized salt in South Ethiopia. The aim of this study was to assess prevalence and factors associated with availability of adequately iodized salt at the households of pregnant mothers in Wonago District, South Ethiopia, 2018.
Methods

Community-based cross-sectional study was conducted from May 14-29, 2018 in Wonago district. Using a stratified two stage random sampling technique, a total of 604 pregnant mothers were included in the study. The level of salt iodine content was determined using the rapid field test kit, considering a value of <15 parts per million (PPM) and ≥15 PPM with the corresponding color chart on the rapid test kit for classification. Multivariable logistic regression model was fitted to identify factors associated with the availability of adequately iodized salt. Adjusted Odds Ratio (AOR) with the corresponding 95% Confidence Interval (CI) was calculated to show the strength of association.
Result

Availability of adequately iodized salt at households of pregnant mothers was 19.9%. House hold head, husband education, average monthly household income and time of salt addition during cooking were independently associated with adequately iodized salt availability. Accordingly, participatory male headed households [AOR=2.1(95%CI 1.08, 3.96)], women with an average monthly household income of ≥ 817 ETB [AOR=7.3(95%CI 3.03, 17.70)] and those who added salt late or after cooking during food preparation [AOR=2.17(1.08, 4.38)] were more likely to utilize adequately iodized salt. Conversely, women whose husband had no formal education were less likely [AOR=0.33(95%CI 0.11, 0.88)] to utilize iodized salt.
Conclusion

Compared to the recommended standard, use of adequately iodized salt among pregnant women is very low. Paternal conditions and household income level are key predictors of use of adequately iodized salt.
Adapting despite “walls coming down”: Healthcare providers’ experiences of Covid-19 as an implosive adaptation
Authors: Cristancho Sayra , Field Emily , Taylor Taryn 
Published: October 2021

Abstract
Background

The Covid-19 pandemic has been a daunting exercise in adaptation for healthcare providers. While we are beginning to learn about the challenges faced by teams during the Covid-19 pandemic, what remains underexplored are the ways team members identified and adapted to these challenges. This is the goal of this study.
Methods

We interviewed 20 healthcare workers at various hospitals in Ontario, who provided care as part of clinical teams during the Covid-19 pandemic. Data was collected and analyzed following Constructivist Grounded Theory principles including iteration, constant comparison and theoretical sampling.
Results

Participants’ accounts of their experiences revealed the process of ‘implosive adaptation’. The ‘reality check’, the ‘scramble’, and the ‘pivot’ comprised this process. The reality check described the triggers, the scramble detailed the challenges they went through, and the pivot prescribed the shifting of mindset as they responded to challenges. These stages were iterative, rather than linear, with blurred boundaries.
Conclusion

That not all adaptations have to be successful during a crisis was the major insight gained by our participants. The language of Reality Check, Scramble, and Pivot provides a framework for teams to talk about and make sense of their approaches to crisis, even beyond the Covid-19 pandemic.

Abstract
Structural variations (SVs) are common genetic alterations in the human genome that could cause different phenotypes and various diseases including cancer. However, the detection of structural variations using the second-generation sequencing was limited by its short read-length which in turn restrained our understanding of structural variations. In this study, we analyzed structural variations in 28 breast cancer-related genes through long-read genomic and transcriptomic sequencing of tumor, para-tumor and blood samples in 19 breast cancer patients. Our results showed that some somatic SVs were recurring among the selected genes, though the majority of them occurred in the non-exonic region. We found evidence supporting the existence of hotspot regions for SVs, which extended our previous understanding that they exist only for single nucleotide variations. In conclusion, we employed long-read genomic and transcriptomic sequencing in identifying SVs from breast cancer patients and proved that this approach holds great potential in clinical application.
Appraisal of the Success of the Instruments of International Commercial Arbitration vs. Litigation and Mediation in the Harmonization of the Rules of Transnational Commercial Dispute Settlement
Authors: Biresaw Samuel Maireg 
Published: October 2021

Abstract
In this study, an effort is made to comparatively assess the until now success of International Commercial Arbitration (hereinafter ICA), Litigation, and Mediation as proven mechanisms of transnational dispute settlement by comparatively analyzing the major instruments of International Commercial Arbitration vis-a-vis the instruments of International Commercial Litigation and Mediation. Accordingly, after detailed scrutiny of the relevant issues, the article argues that, although the ICA is not the only means of transnational commercial dispute resolution, by far, when compared to transnational litigation and mediation, ICA was and will continue to be the most successful (realistic) means of transnational commercial dispute resolution, which plays the dominant role of harmonizing the rules of transnational commercial dispute resolution. However, it is found out that, with time, the harmonization roles of the instruments of transnational commercial litigation and mediation are growing as a viable alternative to ICA.

Agricultural sector in Indonesia contributes greatly to employment, foreign exchange earners, and economic growth. In the export sector, shrimp commodities have the largest portion and become Indonesia's leading commodities. However, Indonesia still cannot become a leader in the world's largest shrimp exporter and only occupies the fourth position of the world's shrimp exporter. There were two goals in the research. First, it was to determine the position of the competitiveness of Indonesian shrimp commodity exports compared to other exporting countries in the United States market. Second, it determined the factors that affected the competitiveness of shrimp exports commodity and made business strategy recommendations for Indonesian shrimp commodities. The research used panel data with a cross-section of seven countries and time series from 2001 to 2017. The result shows that Indonesia has a competitive advantage in the United States market. However, Indonesia must be wary of Ecuador with a higher Revealed Comparative Advantage (RCA) Value and India, the lead exporter in the United States Market. The factors that affect the competitiveness of shrimp exports are Gross Domestic Product (GDP), population, economic distance, and exchange rate of shrimp exporting countries against the US Dollar. Last, the right business strategy for Indonesia is to perform market penetration, market development, and product development strategies.

O presente estudo objetivou analisar a percepção de estudantes do ensino médio sobre sífilis, tricomoníase e herpes em Santa Cruz/RN. Tratou-se de um estudo exploratório e quantitativo realizado com 196 estudantes de escolas públicas de Santa Cruz / RN. Para tanto aplicou-se um questionário, estruturado no modelo escala de Likert. Observou-se que a maioria, 77,04% afirmaram ser solteiros e 53,57% tinham renda familiar até dois salários mínimos. Apenas 20,91% alegam sempre usar preservativos. Os principais motivos para o não uso foram: 29,28% confiança e 17,86% não dispor. A maioria não lembra ou diz não ter sido instruído na escola sobre sexualidade (59,17%). A maioria desconhece formas de transmissão e prevenção sobre sífilis, tricomoníase e herpes. Assim, programas de educação em saúde devem ser instituídos englobando-se as comunidades escolares, serviços de saúde e as famílias, de forma a se reforçar a conscientização dos adolescentes e adultos jovens sobre sexualidade responsável e segura.

O Brasil tem um alto potencial de irradiação solar em sua extensão e sistemas fotovoltaicos isolados da rede estão sendo instalados no país desde o início dos anos 90. Nos primeiros anos, não houve padronização que determinasse níveis mínimos de eficiência em sistemas instalados. Tendo em vista o aumento da geração distribuída por meio de instalações fotovoltaicas nos últimos anos, este artigo busca analisar o atual padrão de validação exigido pelos órgãos governamentais normativos brasileiros com as especificações técnicas do fabricantes que participam do mercado brasileiro de energia fotovoltaica. Este trabalho inclui a análise de degradação de módulos fotovoltaicos a partir de dados coletados em uma instalação na cidade do Rio de Janeiro a fim de fazer uma avaliação qualitativa dos módulos solares instalados no Brasil, e propõe recomendações para minimizar perdas em sistemas fotovoltaicos de geração de energia. O sistema fotovoltaico analisado apresentou desempenho de acordo com o declarado pelo fabricante.

Este estudo tem o objetivo de analisar o desempenho de uma linha produtiva de uma indústria potiguar do ramo de temperos e condimentos usando o Controle Estatístico de Processos (CEP). Para tanto, foram feitas visitas técnicas à empresa para levantamento de dados. Uma linha de produção foi escolhida e mapeada como alvo do estudo. Foram coletadas informações sobre produtividade deste processo durante dezesseis meses entre 2018 e 2019 e escolhidos alguns métodos de controle estatísticos como o Gráfico de Valores Individuais (Gráfico i) e Gráfico de Amplitudes Móveis (), além dos indicadores de Capacidade Potencial (Cp) e Capacidade Real de processos (Cpk). Para tabulação dos dados foram usados os softwares Excel, Minitab e Bizagi Modeler. Por suas características, a pesquisa classifica-se como aplicada, exploratória, quantitativa, com um estudo de caso. Os resultados apontaram que com o Gráfico i, percebeu-se que nenhum valor se posicionou fora dos limites de controle calculados. Já para o Gráfico alguns pontos mereceram maior atenção, indicando alta variabilidade e podendo suscitar comportamento especial e de processo. Com Cp = 0,48 e Cpk = 0,43, o processo foi classificado como incapaz. Algumas causas especiais para esse comportamento foram levantadas, acompanhadas de recomendações.

Um dos maiores problemas enfrentados na agricultura está relacionado as espécies de plantas invasoras em áreas com potencial produtivo. Assim, a busca por melhorias na produção agrícola levou à utilização de herbicidas que podem alterar a qualidade físico-química do solo. Este estudo teve como objetivo analisar as alterações dos atributos físico-químicos do solo, relacionados à classe textural e nutrientes, antes e após a aplicação do herbicida glifosato. Para isso, foi delimitada uma área de 600 m² onde foram coletadas amostras de solo para análises físico-químicas antes e após as aplicações do herbicida glifosato, e comparando se a classes texturais, assim como os nutrientes do solo, sofreram alterações após a aplicação do herbicida. Os parâmetros físicos relacionados às classes texturais do solo evidenciaram que a maior alteração foi encontrada na fração de areia grossa, com um coeficiente de variação (CV) de 70,7%, seguido do silte, com 35,5%, enquanto a argila e a areia fina apresentaram coeficientes de variação de 14,9% e 9,5%, respectivamente. Quanto aos parâmetros químicos relacionados aos nutrientes do solo, o Zn foi o elemento que apresentou o maior coeficiente de variação, com 48,4%, seguido do Fe com 26,0%. Portanto, os resultados obtidos no estudo sugerem que as maiores interferências foram decorrentes da exposição do solo por conta da decomposição e extinção da vegetação protetora, bem como dos possíveis arrastes de partículas provenientes do solo desprotegido, do que, necessariamente, pelos compostos relacionados a aplicação do herbicida no solo.

Published: October 2021

Background:
Human serum albumin (HSA) is one of the most abundant proteins in the
blood plasma, urine as well as in the organic matrix of renal calculi. Macromolecules present in the
urine modulate kidney stone formation either by stimulating or inhibiting the crystallization process.

Objective:
In the present study, the effect of HSA protein on the growth of calcium oxalate monohydrate
crystal (COM) was investigated.

Methods:
Crystal growth assay was used to measure oxalate depletion in the crystal seeded solution
in the presence of HSA. HSA concentrations exhibiting effect on crystal growth were selected
for FTIR and XRD analysis. In silico docking was performed on seven different binding sites of
HSA.

Results:
Albumin plays dual role in the growth of calcium oxalate crystallization. FTIR and XRD
studies further revealed HSA exerted strain over crystal thus affecting its structure by interacting
with amino acids of its pocket 1. Docking results indicate that out of 7 binding pocket in protein,
calcium oxalate interacts with Arg-186 and Lys-190 amino acids of pocket 1.

Conclusion:
Our study confirms the role of HSA in calcium oxalate crystallization where acidic
amino acids arginine and lysine bind to COM crystals, revealing molecular interaction of macromolecule
and crystal in urolithiasis.
