The problem of poverty is still a priority for the Indonesian government. The Indonesian government has launched several programs to assist in alleviating poverty, one of which is the rice program for prosperous families, called Rastra. In the implementation of the Rastra program, it should be carried out objectively so that the distribution of the program can be right on target, but there are still problems in determining the recipients and the accuracy of the distribution of Rastra program. This study aims to combine the ANP and TOPSIS methods in helping to provide recommendations for recipients of Rastra program, besides that in this study also measuring the level of accuracy between the implementation carried out with the real data. In this study, a combination of ANP and TOPSIS methods was used in decision making. The ANP method is used to determine the weight of the criteria used, while the TOPSIS method is used to determine the recommendations for recipients of the Rastra program. The accuracy test was carried out in 13 villages in the Gunung Megang, Muara Enim. The results of the tests carried out obtained an average of 84.10%. This shows that the combination of these two methods can be applied as a solution in providing recommendations for recipients of the Rastra program.

Indonesia is a tropical country, means that Indonesia gets more sun exposure than other countries. Therefore, Indonesia has the potential to develop Renewable Energy, especially solar panels. Solar panels can be used in homes for small scale, as well as on large scale such as power plants. However, electricity generated from solar panels cannot be directly used for some household appliances, because electricity produced is direct current (DC) electricity. So we need a device that can convert DC electricity into AC electricity (Alternating Current) called an inverter. A good inverter is one that has a THD (Third Harmonic Distortion) rating of no more than 5%. High THD can damage electronic equipment. Therefore, this study uses the THIPWM modulation method that is able to reduce THD.

Neste artigo apresentamos uma investigação na área de Onomastics Comparativos cujo objetivo é contrastar dois repertórios onomasticos de línguas e culturas próximas. Realizamos uma análise comparativa que compara os crematórios que designam lojas de vestuário e acessórios e os locais de restauração de duas sintoxicações: a cidade espanhola de Castro e a cidade brasileira de Marechal Cândido Rondon. A análise dos dados considerou os seguintes parâmetros: escopo de origem e linguagens utilizadas, critérios da denominação e estrutura dos crematórios. Os resultados convergentes confirmam a influência da globalização, o prestígio da língua inglesa e a descrição e sugestão como os critérios de palavra mais destacados. Os resultados divergentes indicam que há maior propensão ao primeiro procedimento pela localidade brasileira e ao segundo pela localidade espanhola. Isso leva a uma maior preferência por sitagmas nominais nos usos brasileiros, o que contrasta com o uso de outros tipos de estruturas nos crematórios da cidade espanhola.

Simple and safe modality with high efficacy to treat cervical precancerous lesions before being progressed to cancer is necessary. 3. Trichloroacetic acid (TCA) has those advantages, so it will become an effective treatment for cervical precancerous lesions in the future.
 
ABSTRACT
Cervical cancer becomes one of the most prevalent disease in female worldwide. Human papillomavirus (HPV) is main etiology of cervical cancer, thus this disease is preventable. Before progressed into invasive cervical cancer, cervical precancerous lesions developed and classified into 3 stages: CIN1 (LSIL), CIN2, and CIN3 (CIN2+ also referred as HSIL). World Health Organization (WHO) arranged ‘screen-and-treat’ programme to treat cervical precancerous lesions immediately before it progressed to cancer. However, a simple and safe modality with high efficacy is necessary to accommodate this strategy. Trichloroacetic acid (TCA) has those advantages and some research suggested high efficacy to treat cervical precancerous lesions with simple, safe, and cost-effective. TCA has potential to become effective treatment for cervical precancerous lesions in the future.

Study of Klein Gordon Equation with Minimum Length Effect for Woods-Saxon Potetial using Nikiforov-Uvarov Functional Analysis
Authors: Andaresta Windy , Suparmi A , Cari C
Published: April 2022

The equation of Klein-Gordon for Woods-Saxon potential was discussed in the minimal length effect. We have found the completion of this equation using an approximation by suggesting a new wave function. The Klein-Gordon equation in minimal length formalism for the Woods-Sadon potential is reduced to the form of the Schrodinger-like equation. Then the equation was accomplished by Nikiforov-Uvarov Functional Analysis (NUFA) with Pekeris approximation. This method is applied to gain the radial eigensolutions with chosen exponential-type potential models. The method of NUFA is more compatible by eliminating vanishing the strict mathematical manipulations found in other methods. The energy calculation results showed that angular momentum, radial quantum number, minimal length parameter, and atomic mass influenced it. The higher the radial quantum number and angular momentum, the lower the energg. In contrast to the the minimal length, the energy will increase in value when the minimal length parameter is enlarged. An increase in atomic mass also causes energy to increase as the radial quantum number and angular momentum are held constant.

Use of Accelerating Rate Calorimeter in Reservoir Oil Selection for Air Injection Process
Authors: Zelenko V. , Solignac F.
Published: April 2022

The paper proposes an interpretation of the phenomena observed on several ARC (Accelerating Rate Calorimeter) tests performed with different crude oils. The ARC apparatus was used as a closed system and the gas formed at the end of the reactions were analyzed by chromatography. Low Temperature Oxidation (LTO) and Negative Temperature Coefficient (NTC) areas were identified during these tests. The proposed interpretation is based on an analogy with the reaction mechanisms occurring during light saturated hydrocarbon oxidation. The determination of kinetics parameters for oxidation reactions was investigated. In the meantime, limitations of the ARC device, when used as a closed system, clearly appeared. The conclusion is that not only the determination of basic kinetics parameters is generally not possible with ARC tests, but also that a serious selection of oil reservoir for air injection technique based on these tests seems questionable.

Introduction

Success of oil recovery by air injection greatly depends on knowledge of reaction mechanism between oxygen and oil in porous media. Oil oxidation during in-situ combustion involves numerous competing reactions occurring through different temperature ranges. Generally, in order to simplify the studies, investigators classify the reactions in three steps (Dubdub1 et al; Brigham2 et al).

- First, the low temperature oxidation (L TO) reactions, which are heterogeneous (gas/liquid) and generally produce polar compounds. For some light oils, if the reservoir conditions are convenient, L TO can produce mainly carbon oxides and water at long time (Solignac3).

- Then comes the medium temperature oxidation (MTO) : oxidation reactions are slow, therefore cracking/pyrolysis which leads to coke, becomes the main phenomenon.

- Finally, high temperature oxidation (HTO) : oxygen reacts with unoxidized oil, polar compounds and coke (Belgrave4 et al; Solignac3) to give carbon oxides and water.

This paper describes ARC experiments on crude oil oxidation and proposes an analysis of experimental data, using works (Ben-Ai'm5 et al; Le Chatelier6 et al; Newitt7 et al; Cathonnet8 et al) on light saturated hydrocarbons (CICIO). We compare heat rate behaviors measured by the calorimeter (Fig. 1) with zones of reactivity (cool and normal flames) occurring during oxidation of light saturated hydrocarbons in the gas phase.
Build a Bioinformatic Analysis Platform and Apply it to Routine Analysis of Microbial Genomics and Comparative Genomics

Published: April 2022

More and more frequently, genomics and comparative genomics have been used as routine methods for general microbiological research. However, using several tools or even writing some scripts are required for completing a simple analysis, which is complicated for most biological researchers. To simplify the operation process, particularly for the convenience of microbiologists, here we have developed PGCGAP, a comprehensive, malleable, and easily installed prokaryotic genomic and comparative genomic analysis pipeline. PGCGAP implements genome assembly, gene prediction and annotation, genome and metagenome distance estimation, phylogenetic analysis, COG annotation, pan-genome analysis, inference of orthologous gene groups, variant calling and annotation, and screening for antimicrobial and virulence genes. Although we have tried our best to simplify the installation and usage of PGCGAP, it may be difficult for non-bioinformaticians to master it. Therefore, a protocol was created to help microbiologists without any experience in bioinformatics to establish their bioinformatics platform and perform routine analyses. This protocol shows how to choose the equipment to install a Linux subsystem on a laptop with a Windows 10 system, to install the PGCGAP and perform all analyses with an example dataset (This protocol applies to PGCGAP version 1.0.34 and later). The protocol requires a basic understanding of Linux, so an additional web page was written to help uninitiated users learn Linux and whole-genome sequencing (https://github.com/liaochenlanruo/pgcgap/wiki/Learning-bioinformatics or http://bcam.hzau.edu.cn/linuxwgs.php).
Automated, quantitative Fast FLIM-FRET (qF3):A step-by-step protocol to measure dissociation constants for protein-protein interactions in live-cell screening applications
Authors: Osterlund Elizabeth J. , Hirmiz Nehad , Pemberton James M. , Fang Qiyin , Andrews David W.
Published: April 2022

Fluorescence lifetime imaging microscopy (FLIM) can detect Fӧrster resonance energy transfer (FRET) to measure protein-protein interactions in live cells. Traditional FLIM-FRET uses relative intensities to represent protein expression, consequently limiting users to a qualitative comparison of resulting binding curves. In our quantitative Fast FLIM-FRET (qF3) method we use fluorescent protein standards to convert intensity to concentration and then fit binding curves to determine live-cell apparent dissociation constants (Kd). To acquire measurements with high spatial and temporal resolution in live cells we built a multiplexed system for rapid data acquisition. In this way, complete quantitative binding curves can be generated for hundreds of high-resolution regions of interest from 384 samples in less than 24 hours. In addition, we introduce new automated criteria for quality control in screening. We applied this method to screen a large set of BH3 mimetic drugs targeting BCL-2 family protein dimeric interactions in live cells (associated publication in Science Advances). Here we provide a step-by-step protocol for the qF3 method, which can be adapted for use with other proteins of interest on a multitude of other FLIM-FRET platforms, enabling future automated analysis of protein-protein interactions in live cells at even faster speeds.

Published: April 2022

The current study evaluated antibacterial activity of dichloromethane and methanol (DCM-MeOH) extracts of four Kenyan orchid species against three selected bacterial strains. Extracts of E1 (Ansellia africana), E2 (Trydactylescottelli), E3 (Polystachyabella) and E4 (Liparis bowkeri) were screened for antibacterial activity againstStaphylococcus aureus, Bacillus subtilis and Pseudomonas aeruginosausing agar disc diffusion. Ampicillin was included as a positive control.Qualitative analysis revealed the presence of flavonoids, saponins, alkaloids, tannins, terpenoids, steroids and glycosides. Trydactyle scottelli and Polystachyabella extracts revealed stronger presence of tannins and steroids respectively compared to the others. All extracts showed varying levels of antibacterial activity against the test bacteria. However, extracts of Polystachyabella and Liparis bowkeri against Bacillus subtilis and Ansellia africana against Pseudomonas aeruginosa exhibited higher activities similar to that of Ampicillin. The study further showedthat the DCM-MeOH extracts of the four orchids contain potential bioactive compounds that should be further analysed for conventional and traditional management of bacterial infections.

Published: April 2022

Emulsified solid particles adsorbed at the oil–water interface can stabilise Pickering emulsions by acting as a physical barrier to the coalescence of oil droplets. Cellulose nanofibres (CNFs) have been used in food-grade Pickering emulsions because of their excellent performance as a low cost and sustainable material. Nicotinamide mononucleotide (NMN) is a small-molecule zwitterion with polar functionality capable of interacting with the CNFs. The ability of cationic CNFs and NMN to co-stabilise sunflower oil Pickering emulsions was investigated under various conditions using methods such as contact angle measurement, creaming stability, rheology, microscopy, thermal stability, and water-holding capacity. Emulsions with ultra-high stability, good gelation, and high plasticity were obtained using single-step shear dispersion with 0.25 wt% CNFs, 0.05–0.3 wt% NMN, and near-neutral pH. NMN stabilised the oil–water interface through electrostatic interactions and hydrogen bonding with CNFs. NMN transferred into the aqueous phase and interacted with CNFs to form a complex with a three-dimensional network structure, which improved the bulk viscosity and steric hindrance of the emulsion and created more compact adsorption of CNFs at the oil–water interfaces. Overall, the synergistic effects of various factors allow NMN to effectively co-stabilise Pickering emulsions with CNFs, making it an exciting method that can be used to encapsulate oil-soluble substances.

One of the most common disorders among school-age children is attention deficit hyperactivity disorder (ADHD). Although the symptoms mostly appear between the ages of five and seven, some can be traced back to early childhood. Objective: In this study, we identified and ranked early childhood characteristics that can correctly predict ADHD diagnosis at the age of seven based on none-clinical data, and then used those features in a computer model to enhance the prediction accuracy. Method: The data used in this study was from the Millennium Cohort Study, which contains comprehensive information about the biological, genetic, and environmental characteristics of children and their parents. In our analysis, we conducted a complete mining process, including feature selection (regression and Support Vector Machine) and modeling (Artificial Neural Network) to select and use proper characteristics to predict ADHD diagnosis, and finally, evaluation (10-fold cross-validation) to assess the accuracy of the prediction. Results: The proposed mining process selected and categorized 28 features (out of 3908) as the most important predictors, some[may] have not been reported by other studies before. These features belong to different age groups and both children and their parents. Total difficulty score of SDQ, child’s weight, total health, and parent’s income were among the features with the most predictive power. The results from the final model show an F1-score of 82.85%, which, compared to previous studies, shows a significant improvement.

In order to realize the prediction on the slope stability,the slope in Dingjiafen in Chuxiong, Yunnan, China was selected as the worksite to be studied,the critical soil thickness (Dcr) when the landslide was started under saturated condition of slope and the maximum soil thickness（Dmax）when the landslide was started under unsaturated condition of slope were inferred by using the slope stability physical model. Based on digital elevation model (DEM), the critical soil thickness and maximum soil thickness of each slope unit at the start of landslide were calculated,the criterion of slope instability was determined, and the influence of rainfall infiltration process, soil thickness, the physical and mechanical properties of soil, slope surface and the bedrock surface topography on slope stability was analyzed.The analysis results were verified by means of modeling and numerical simulation calculation of FLAC3D. The research results shows that the critical soil thickness and the maximum soil thickness of the slope unite with different topographies at the start of landslide are not the same. Besides, the slope units with the critical soil thickness between 1m~3m were located at the right and left side of the Chu-Meng highway, which conformed with the actual position of sliding. Simulating the thickness of soil layer when slope units were at the critical state of landslide by using this method can predict the stability of slopes.

The purpose of this paper is to explore which dimensions impact hospital performance in previous researches. Chinese public hospitals reform was to attach importance to the public welfare of hospitals, since the positions of hospitals are the place to heal the dead, heal the wounded, and save patients. World Health Organization (WHO) defines patient safety as “reducing the unnecessary injury related to health care to an acceptable minimum risk control process.” Based on a systematic review of the literature, the article found that limited researches on patient safety culture on hospital performance under China environment. This study suggests that future Chinese researchers can explore the relationship between patient safety culture and hospital performance.

PurposeSocial support facilitated healthy behaviours in people living with and beyond cancer (LWBC) before the COVID-19 pandemic. Little is known about how social support impacted their health behaviours during the pandemic when social restrictions were imposed. The aim of this study was to qualitatively explore how social support impacted the health behaviours of people LWBC during the COVID-19 pandemic.MethodsSemi-structured interviews were conducted via telephone with 24 adults living with and beyond breast, prostate and colorectal cancer. Inductive and deductive framework analysis was used to analyse the data. ResultsSix themes developed. These were 1) Companionship and accountability as motivators for physical activity, 2) Familial social influence increasing alcohol consumption, 3) Importance of friends, communities and government in maintenance of food security, 4) Partner support in food practices, 5) Informational support as important for behaviour change, and 6) Validation of health behaviours from immediate social networks. ConclusionThis study found that companionship, social influence, instrumental support, informational support and validation impacted the health behaviours of people LWBC during the COVID-19 pandemic. Interventions for people LWBC could recommend co-participation in exercise with friends and family; promote the formation of collaborative implementation intentions with family to reduce alcohol consumption; and encourage supportive communication between partners about health behaviours. These interventions would be useful during pandemics and at other times. Government policies to help support clinically extremely vulnerable groups of people LWBC during pandemics should focus on providing access to healthier foods.

Background: Transarterial radioembolization (TARE) with yttrium-90 microspheres is a clinically effective therapy for hepatocellular carcinoma (HCC) treatment. This study aimed to perform a systematic review of the available economic evaluations of TARE for the treatment of HCC.Methods: The Preferred Reported Items for Systematic reviews and Meta-Analyses guidelines was followed by applying a search strategy across six databases. All studies identified as economic evaluations with TARE for HCC treatment in English or Spanish language were considered. Conversions were performed using 2020 purchasing-power-parity ($US PPP).Results: Among 423 records screened, 20 studies (6 cost-analyses, 3 budget-impact-analyses, 2 cost-effectiveness-analyses, 8 cost-utility-analyses, and 1 cost-minimization analysis) were finally included (13 European, 6 USA and 1 Canadian). The assessed populations included early- (n=4), and intermediate-advanced-stages patients (n=15). Included studies were evaluated from a payer perspective (n=20) and included both payer and social perspective (n=2). TARE was compared with transarterial chemoembolization (TACE) (n=9) or sorafenib (n=11). Life-years gained for TARE ranged from 1.3 to 3.1 vs. TACE and from 1.1 to 2.53 for TARE vs. sorafenib. TARE was associated with lower treatment cost in ten studies. TARE cost varied widely according to Barcelona Clinic Liver Cancer (BCLC) staging system and ranged from 1,311 PPP/month (BCLC-A) to 71,890 PPP/horizon time 5 years (BCLC-C). The incremental cost-utility ratio for TARE vs TACE resulted in a $PPP 17,397/Quality-adjusted-Life-Years (QALY) (n=1) and for TARE vs. sorafenib ranged from dominant (more effectiveness and lower cost) to 3,363 PPP/QALY.Conclusions: Economic evaluations of TARE for HCC treatment are heterogeneous. Overall, TARE is a cost-effective short- and long-term therapy for the treatment of intermediate-advanced HCC.

A low-cost functionalization method was used to treat diatomite, and an efficient adsorbent for ammonia nitrogen was prepared by optimizing the functionalization conditions. The functionalized diatomite (DTCA-Na) was characterized by SEM, EDS, BET, XRD, FT-IR and TG. The results demonstrate that DTCA-Na has excellent adsorption performance after being modified with H2SO4 (60.00 wt.%), NaCl (5.00 wt.%) and calcination at 400 °C for 2 h. While studying the effect of adsorption factors on the removal of ammonia nitrogen, the kinetic and thermodynamic behaviors in the adsorption process were discussed. The removal efficiency of the simulated wastewater with the initial ammonia nitrogen concentration of 10.00 mg/L by the DTCA-Na was more than 80% when the contact time was 60 min, pH was 6-10, the dosage of adsorbent was 1.00 g, the temperature was 25 °C. The adsorption process of ammonia nitrogen was conformed to the pseudo-first-order and Langmuir isothermal model. The removal efficiency of ammonia nitrogen was still above 80% after 5 times adsorption-desorption experiments. The DTCA-Na has a brighter prospect of application in the field of ammonia nitrogen wastewater treatment due to its excellent adsorption performance and low-cost advantage.

Published: April 2022

Background
COVID-19 and its associated social restrictive measures and lockdowns exacerbated the use of social media and other technological facilities for communication. This study, therefore, examined Ghanaian students’ social media use and its relationship with fear of COVID-19, paying close attention to the moderating role of gender.
Methods
Data were collected between June and July 2020 among a sample of 209 students via online measures on social media use and fear of COVID-19.
Results
Findings revealed that social media use had a small and positive association with fear of COVID-19 (r = 0.18, p = 0.009). The mean scores of these variables did not differ by gender. However, moderation analysis revealed that increased social media use raised the fears of COVID-19 of female students (B=-0.24, p = 0.034).
Conclusion
Although social media was used for connecting with people and accessing pandemic-related information, our findings clearly suggest that overuse or over-engagement may just be problematic, especially for females. Aside from developing interventions to reduce students’ fears of COVID-19, appropriate usage of social media should be advocated.

Background: BLCA is one of the most common genitourinary malignancies in the world, but its pathogenic genes have not been fully identified and the treatment outcomes are still unsatisfactory. Although the members of 2', 5'-oligoadenylate synthetase (OAS) gene family are known involved in some tumorous biological processes, the roles of the OAS gene family in BLCA are still undetermined. Methods: By combining the vast bioinformatic datasets analyses of BLCA and the experimental verification on clinical BLCA specimen, we identified the expressions and biological functions of OAS gene family members in BLCA with comparison to normal bladder tissues. Results: We showed that the expression levels of OAS gene family members were higher in BLCA than in normal bladder tissues. The expression levels of most OAS genes had correlations with prognosis, genomic mutation, methylation and infiltration levels of CD4+T cells, CD8+T cells, neutrophils, and dendritic cells in the microenvironment of BLCA. In addition, high expression levels of OAS1, OAS2, OAS3, and OASL predicted better overall survival in BLCA patients. Conclusions: We conclude that the expression levels of OAS genes may be considered as a signature of BLCA and can reflect immune cell infiltration in BLCA microenvironment and predict the overall survival of BLCA. The study may provide new insights into the diagnosis, treatment, and prognosis of BLCA.
