Authors: Villalobos-Moreno Alfonso , Luke-Z Jesús Emilio , Villamizar-Cobos Jorge 
Published: September 2020

Introducción. La mosca de la piña (Melanoloma viatrix Hendel, 1911) fue reportada por primera vez en Colombia en 1991, y se ha convertido en una plaga limitante en el cultivo de piña en este país. Hay escasa información sobre la especie y se requiere estimar su distribución, fluctuación y densidad, para diseñar estrategias de manejo integrado de plagas. Objetivo. Evaluar atrayentes alimenticios como mecanismo de muestreo de Melanoloma viatrix Hendel. Materiales y métodos. Los ensayos se realizaron en fincas piñeras del municipio de Girón, Santander, Colombia, durante el inicio de la primera temporada de lluvias de 2003. Se evaluaron ocho atrayentes alimenticios dentro de trampas McPhail ubicadas en seis bloques al azar dentro de tres cultivos comerciales de piña de la variedad Perolera. Resultados. Los ensayos con atrayentes alimenticios dentro de trampas McPhail, capturaron más de 13 000 individuos, incluyendo dípteros, lepidópteros, himenópteros, neurópteros, hemípteros y ortópteros, pero solo 138 ejemplares de la especie de estudio. Conclusión. Se observaron diferencias significativas en las capturas de M. viatrix, siendo trozos de cáscara, extracto de cáscara y jugo natural de piña, los atrayentes que presentaron los mejores resultados de captura.

Introduction. Coffee (Coffea arabica L.) is an important crop in producing countries like Peru, where approximately two million families depend on its production, distribution, and marketing. But in recent years, climate change has increased the presence of coffee leaf rust - CLR (H. vastatrix), a disease that has decreased Peruvian production by up to 27%. Objective. Monitor the severity of CLR in different genotypes of coffee cv. Typica from April-2017 to March-2018. Material and methods. The experiment was carried out in the coffee germplasm bank at the Development Regional Institute (IRD)-Selva of the Universidad Nacional Agraria La Molina. The severity and the area under the disease progress curve (AUDPC) in the lower, middle, and upper part of coffee trees were quantified. Result. There was high severity and AUDPC in the dry season (low precipitation) compared to the rainy season (high precipitation). Severity and AUDPC gradually decreased from the bottom to the top of the plant (lower>middle>upper). Also, UNACAF-24A, UNACAF-16, UNACAF-158, and UNACAF-162 genotypes stood out by showing lowest severity (0-1.1 %) and AUDPC (0-714) in the experiment. Conclusion. In this experiment, the genotypes in dry season presented high peaks of severity and UDPC of CLR, meanwhile, in rainy season the presence of CLR was lower. However, in both seasons, severity and AUDPC gradually decreased from the lower third to the upper thirf of the plant. Finally, UNACAF-24A, UNACAF-16, UNACAF-158, and UNACAF-162 presented the lowest degrees of severity of CLR.

Authors: Paniagua-Molina Javier , Solórzano-Thompson Johanna 
Published: September 2020

Introduction. Palm cultivation allows oil to be obtained for human and industrial consumption. Some of its development has been achieved through associations of agricultural producers, who have had access to financing to build industrial plants for oil extraction and refinement, which is of great importance to the economy developing countries. Objective. To demonstrate how strategic and risk management influence the profitability and value of the small palm oil industrializer business. Materials and methods. Financial, technical, market, and production indicators were used in a price forecast model. The Monte Carlo simulation method was performed and a time series model was fitted to forecast the international price of palm oil. Subsequently, a univariate structural econometric model was adjusted to forecast revenue based on international price and other variables. Finally, a parameterized cash flow was developed that incorporated the results of the previous models to estimate the value of the business. Results. The international oil price forecast showed high volatility that directly affected the organization’s revenue forecasts and conveyed its effect to cash flows. The value of the business and equity was negative, and in the face of debt restructuring scenarios and the elimination of unproductive assets, they improved considerably. Conclusion. Low-diversified palm oil production companies had a high exposure to changes in international prices which, together with high levels of debt for fixed asset investments with long recovery periods, affect their cash flow, the value of the company, and its assets.

Objective: To assess health demographic profile of Uriri sub-County in Migori county, Kenya.
Study Design: Prospective study using a questionnaire
Study Setting: Uriri Sub-County in Migori County, Kenya
Study Participants/Subjects: Mothers with children under the age of five years. This was done purposely in order to capture the relevant information required on maternal, child health and other areas.
Results: The survey revealed many gaps that needed interventions both locally and from the National level. The literacy levels were still wanting with 70% not going past tertiary levels of education. This had an impact on diverse areas socio-economically starting with family life with children occupying 56% of the total house hold composition. This led to low literacy levels. The finding also revealed poor food security situation in Uriri constituency, with over 70% admitting they did not have enough food stocks in their households to last them till the next harvest. Three hundred and forty one (50.3%) mothers did not deliver in the available health facilities and 40.7% did not attend Antenatal Clinics.
Conclusion: Literacy especially amongst women is quite important in the making of a community, even though both sexes play an important part in passing education down their generations. Lack of education and information on pertinent issues of family care led to increased numbers of children which directly impacted on the overall population. Lack of financial capacity and economic empowerment was part of the reason for food insecurity in the area. The study showed that half of the women in Migori County do not visit the health facilities available in the county. This is in spite of the Government providing health resources in the region.

The disease caused by corona virus is come under the category of sudden/acute infectious disease nwhich is caused by SARS-CoV-2. At time WHO stated that disease of COVID-19 is a worldwide contagious illness. According to WHO, this contagious disease is a 3rd acute contagious disease which is caused by infection due to corona virus in the current century after anticipated SARS. Till now the exact mechanism of COVID-19, how it produces its ill effects to the host body is still not clear.
This disease of COVID-19 shows mild or negligible symptoms in most of the population, but usually it progresses with people of old aged groups or patient having low immunity. In the cases it started with dyspnea, progress towards pneumonia and might lead to multiple organ failure. Now a days most of the people or patients show no symptoms or otherwise are asymptomatic. Final diagnosis of the virus is confirmed by presence of virus in the secretions of respiratory tract with the help of molecular tests. First case of this pandemic was from city of wuhan, from china on 7th January, 2020.

Published: September 2020

Treasures about Islam in Indonesia cannot be separated from pesantren (Islamic boarding school). The contribution to the development of social and cultural, especially through the preservation of local culture. This paper discusses social capital and its transformations in Pondok Pesantren Sidogiri, Pasuruan Regency. This study applied ethnography method. The research findings show internalized social capital includes social interaction ties such as routine recitations, alumni bonds, and togetherness inthe style of pondok pesantren, istighozah, haul, akhir sanah and cooperation with other institutions outside pesantren. Norms consist of love and obedience to masyaikh also his family, santri Sidogiri are one brotherhood, discipline, barokah (divine blessing), and independence in the economy, as well as honest and trustworthy behavior. Shared vision contain the development of science and institutions for the affirmation of ahlus Sunnah wa jamaah, khidmah lil ma’had khidmah lil ummah, ibadillah sholihin, simplicity, and creating entrepreneurship. Meanwhile, the transformation of social capital are the expansion of the pesantren network through the development of the organizational structure - establishment of new institutions and institutionalize of khidmah lil ma'had and khidmah lil ummah. The social capital has a big enough impact, not only to create santri who own a strong religious knowledge and entrepreneurial spirit but also as a major trigger in the success of Pondok Pesantren Sidogiri in developing its economic business. The productive culture attached to social capital, moreover the increasing stock of social capital intend to combines two aspects namely clinging ahlusunnah wal jamaah and responding to advancement of science and technology.

Workflow for Sensitivity Analysis and Decision Making on the Lower Limit of the Mud-Weight Window in an Overpressured Formation
Authors: Paglia Jacopo , Eidsvik Jo , Cerasi Pierre 
Published: September 2020

Summary
When drilling a well, it is important to choose a reasonable mud density to ensure safe operations. This is not a trivial task because a balanced mud-weight has a complex relation to the uncertain formation conditions and properties. This paper presents a method for conducting sensitivity analysis (SA) over the uncertainties involved in the mud-weight window (MWW) assessment, to learn the most important input parameters for the mud density. The uncertainties in the parameters are taken into account using predrill realizations of the formation conditions (vertical stress, minimum horizontal stress, pore pressure, and temperature) and properties (unconfined compressive strength, tensile strength, friction angle, and porosity). The limit pressures of the MWW are computed to avoid shear and tensile failure. The software used to study well stability returns a mud window that could enable underbalanced drilling while still avoiding borehole collapse; this is emphasized by equating the lower stability limit with shear failure and not pore pressure. However, drilling below the pore-pressure limit entails risks with regard to kicks or blowouts. The Mohr-Coulomb failure criterion is used, but other possible shear failure criteria are discussed as well. The output from the SA is used to evaluate how the possibility of gathering more information about the most relevant parameters can improve our knowledge about the appropriate mud density. This is done in the form of value of information (VOI) analysis, coupling the uncertain variables with drilling decisions in a tradeoff between costs and risks. The interest is on deciding what information to acquire when, at a given depth, the drilling operator must decide on whether to keep drilling or set casing. Additional well data are valuable when they can materialize in improved decision making. The case study presented is from an overpressured shale layer in a field in the North Sea. The focus is on the lower allowed well pressure of the mud-weight window for a vertical well, exploring the possibility of underbalanced drilling. The SA shows that the most important uncertainties in this case are pore pressure, unconfined compressive strength, and minimum horizontal stress. The most valuable information-gathering strategy is to observe these main three parameters, which is worth USD 386,980 when acquisition costs are subtracted. The VOI analysis further indicates that data about the rock's unconfined compressive strength are the most valuable in this case, and if the decision maker can afford to acquire only one data type, this should be chosen. Although these results are case specific, we believe that a similar workflow could be useful in other drilling situations.

Published: September 2020

Abstract
Background Sagittal abdominal diameter (SAD) is an anthropometric index associated with visceral adiposity. It remains unclear whether SAD and its socio-economic correlates differ in women and men, which limits the epidemiological and clinical applications of the SAD measurement. The aims of this study are to examine the sex differences in SAD and its socio-economic correlates.Methods A complex stratified multistage clustered sampling design was used to select 6,975 men and 7,079 women aged 18 years or more from the National Health Nutrition and Examination Survey 2011-2016, representative of the US civilian non-institutionalized population. SAD was measured in accordance to the standard protocols using a two-arm abdominal caliper. The sex differences in SAD and its socio-economic correlates were evaluated by performing weighted independent t tests and weighted multiple regression. Results SAD was lower in women than in men in the entire sample, as well as in all the subgroups characterized by age, race, birth place, household income, and body mass index except for non-Hispanic blacks and those with household income < $20,000. Adjusted for other characteristics, age, birth place, household income, and body mass index were associated with SAD in both women and men. Black women were associated with higher SAD then white women (p<.0001), and Hispanic and Asian men were associated with lower SAD than white men (both p<.01). Women born in other countries were more likely to have lower SAD than women born in the US (p<.0001), and so were men (p=.0118). Both women and men with a household income of <$75,000 had higher SAD than those with an income of over $75,000. The associations of age, race, and household income with SAD differed in women and men.Conclusion SAD is lower in women than in men, in the general population as well as in the most socio-economic subgroups. While socio-economic correlates of SAD are similar in women and men, the associations of age, race, and household income with SAD vary across sex.

Abstract
Background: The outbreak of the coronavirus disease-19 (COVID-19) has caused enormous stress among the public in China. Intellectual input from various aspects is needed to control COVID-19, including understanding of the public’s emotion and behaviour and their antecedents from the psychological perspectives. Drawing upon the cognitive appraisal theory, this study examined three cognitive appraisals (i.e., perceived severity, perceived controllability, and knowledge of COVID-19) and their associations with a wide range of emotional and behavioural outcomes among the Chinese public.Methods: Participants were 4607 citizens (age range: 17–90 years, Mage=23.71 years) from 31 provinces in China and they took part in a cross-sectional survey online.Results: The results showed that the public’s emotional and behavioural reactions were slightly affected by the outbreak of COVID-19. Moreover, the public had limited participation in the events regarding COVID-19 but actively engaged in precautionary behaviour. In addition, results of structural equation model with latent variables revealed that the three appraisals were differentially related to the outcome variables (i.e., negative emotion, positive emotion, sleep problems, aggression, substance use, mobile phone use, social participation, and precautionary behaviour).Conclusions: The findings highlight the utility of cognitive appraisal, as a core process of coping stress, in explaining the public’s emotion and behaviour in the encounter of public health concern. Practically, the findings facilitate the government and practitioners to design and deliver targeted intervention programs to the public affected by COVID-19.

Authors: ma xuyang , Ding Ying , Zeng Li 
Published: September 2020

Abstract
Background: The potential correlation between H2AFY (also known as MacroH2A1) and the clinical characteristics of hepatocellular carcinoma (HCC) patients was analysed through gene expression profiles and clinical data in The Cancer Genome Atlas (TCGA) database, and the diagnostic and prognostic value of H2AFY in HCC was discussed. Methods: The gene expression data of HCC and the corresponding clinical characteristics of HCC patients were downloaded from the TCGA database. The differences in H2AFY in normal liver tissues and HCC were analysed. The relationship between H2AFY and clinical characteristics was analysed by Wilcoxon signed-rank test, logistic regression and Kruskal-Wallis test. The Kaplan-Meier method and the Cox regression method were used to analyse the relationship between overall survival and clinical characteristics of the patients. An ROC curve was used to predict the diagnostic value of H2AFY in HCC. Gene set enrichment analysis (GSEA) was used to analyse the pathway enrichment of H2AFY. Result: Compared with normal liver tissues, H2AFY was significantly highly expressed in HCC. H2AFY was positively correlated with the age, clinical stage, G stage (grade) and T stage (tumor stage) of liver cancer patients. Higher H2AFY expression predicted a poor prognosis in HCC patients. Cox regression analysis suggested that H2AFY was an independent risk factor for the prognosis of HCC patients. The ROC curve suggested that H2AFY had certain diagnostic value in HCC. GSEA suggested that H2AFY was correlated with lipid metabolism and a variety of tumour pathways. ﻿Conclusion: Our study showed that H2AFY was significantly overexpressed in HCC. H2AFY may be a potential diagnostic and prognostic marker for HCC, and high expression of H2AFY predicts a poor prognosis in patients with HCC.

Abstract
[Please see the manuscript file pdf to view the full abstract.]Background: Data about herpesvirus microRNA motifs on human circular RNAs suggested the following statistical question. Consider independent random counts, not necessarily identically distributed. Conditioned on the sum, decide whether one of the counts is unusually large. Exact computation of the p-value leads to a specific algorithmic problem. Given elements in a set with the closure and associative properties and a commutative product without inverses, compute the jackknife (leave-one-out) products ( ).Results: This article gives a linear-time Jackknife Product algorithm. Its upward phase constructs a standard segment tree for computing segment products like ; its novel downward phase mirrors the upward phase while exploiting the symmetry of and its complement . The algorithm requires storage for elements of and only about products. In contrast, the standard segment tree algorithms require about products for construction and products for calculating each , i.e., about products in total; and a naïve quadratic algorithm using element-by-element products to compute each requires products.Conclusions: In the herpesvirus application, the Jackknife Product algorithm required 15 minutes; standard segment tree algorithms would have taken an estimated 3 hours; and the quadratic algorithm, an estimated 1 month. The Jackknife Product algorithm has many possible uses in bioinformatics and statistics.
