Authors: Moreira Diego Gouveia
Published: July 2020

A política no Brasil, desde a ditadura, é acompanhada por uma crescente busca por visibilidade e direitos. A discussão sobre políticas identitárias LGBTQIA+ ganhou outros contornos no cinema nacional com o avanço dos movimentos sociais. O documentário "Meu Corpo é Político" (2017) aborda o dia a dia de quatro pessoas transgêneras. O objetivo deste artigo é compreender as estratégias discursivas empregadas pelo filme para pautar as políticas identitárias LGBTQIA+. Para isso, foi realizada uma revisão bibliográfica ligada à teoria queer bem como uma análise dos discursos visuais e verbais do filme. Por fim, constata-se que o documentário fortalece a visibilidade das pessoas trans, colaborando com a discussão sobre direitos sociais e políticos de transexuais ao criticar o sistema cisnormativo.
Quando a semiótica se tornou uma teoria da comunicação?
Authors: Martino Luis Mauro Sá
Published: July 2020

O objetivo deste texto é compreender como uma perspectiva originária da Linguística e/ou da Filosofia se tornou uma referência teórica para a Comunicação. Este artigo destaca alguns momentos dessa aproximação,  examinando, a partir de pesquisa bibliográfica, a presença da Semiótica em 26 livros-textos de Teoria da Comunicação publicados entre 1969 e 2018. A análise das evidências sugere que: (1) não há consenso sobre sua pertinência: 14 dos livros analisados não a incluem entre as teorias da comunicação, e apenas três detalham o tema; (2) embora presente na área desde a década de 1960, o tema ganha espaço como “teoria da comunicação” nos anos 1990; (3) não há quase distinção entre abordagens semióticas, apresentadas como teoria dos signos e geralmente associada à Linguística e à Teoria da Informação. Estes resultados são discutidos no contexto da atual pesquisa de epistemologia da Comunicação.

Published: July 2020

El desarrollo económico descontrolado y la sobreexplotación de los recursos naturales han aumentado los niveles de contaminación sobre el recurso hídrico a pesar que existen diferentes tecnologías para el tratamiento de residuos líquidos, uno de los más utilizados es el tratamiento primario avanzado, el cual consiste en la coagulación/floculación y sedimentación de materiales particulados presentes en el agua. Este tipo de tratamiento habitualmente se ejecuta haciendo uso de polielectrolitos sintetizados químicamente. En el presente trabajo se evaluó la eficiencia que tienen los coagulantes naturales extraídos de la semilla del aguacate y del mucílago del café en el tratamiento primario avanzado de aguas residuales, se determinó el desempeño de cada extracto en términos de reducción de color y turbiedad en el tratamiento de aguas residuales domésticas. Los resultados obtenidos señalan que el extracto de la semilla del aguacate da lugar al aumento tanto en turbiedad como en coloración, por su parte el mucílago del café permitió remover el 65,29% de la turbiedad, indicando que este compuesto puede servir como un coagulante preliminar o auxiliar en el proceso de tratamiento primario de aguas residuales.

Contextualización: La determinación de nitrógeno foliar es utilizada como uno de los índices que mide la necesidad nutricional de la planta en los cultivos de palma de aceite. También fue de igual importancia en esta investigación es enfocarse a una tendencia en general de los laboratorios llamada química verde, la cual se centra en minimizar la utilización de reactivos químicos en los diferentes análisis de laboratorio.

Vacío de conocimiento: usando espectroscopía de infrarrojo medio y cercano (MIR y NIR) se pretendió minimizar en gran parte la generación de contaminantes producidos por el método de Kjeldahl, además de reducir los tiempos de análisis.

Objetivos: determinar la cantidad de nitrógeno foliar mediante la construcción modelos predictivos a partir de los espectros de infrarrojo medio y cercano para la determinación de nitrógeno foliar usando como método de referencia Kjeldahl.

Metodología: En el desarrollo del experimento se analizaron 198 muestras foliares de palma y se tomaron sus respectivos espectros infrarrojos MIR y NIR. Cada uno de los espectros fue pretratado por diferentes métodos matemáticos para corregir efectos de dispersión de la radiación. En total se realizaron 8 pretratamientos a cada uno de los espectros incluyendo los espectros crudos. Estos fueron tomados para elegir el mejor modelo de predicción tanto para los espectros NIR como para los espectros MIR.

Resultados y conclusiones: Utilizando el pretratamiento de SNV en el modelo se obtuvo un RMSE de 0.265 y un R2 de 0.51 para el infrarrojo cercano y para el infrarrojo medio, el modelo formado con la absorbancia de los espectros sin pretratar arrojó valores de RMSE de 0.245 y un R2 de 0.46. aunque puede utilizarse de una forma general como modelo de predicción, se puede observar puntos anómalos que amplían el error y disminuyen el R2, a partir de estos datos se puede evidenciar la necesidad de clasificar de una mejor forma los grupos de muestras foliares y si es necesario realizar modelos de predicción para cada uno de los grupos.

Este artículo pregunta por las posibilidades de lo que somos capaces al reconocernos como cuerpos deambulando que se encuentran con otros cuerpos ¿Qué es lo que podemos? ¿Qué implica una epistemología ambiental que ponga en primer plano la sensibilidad, el cuerpo, lo sentido y los afectos? Comenzamos con una discusión sobre las dicotomías, los monismos y dualismos, para ofrecer luego una propuesta desde las multiplicidades, los cuerpos entre cuerpos, y los encuentros entre alteridades radicales ¿Es posible abrir una vía media que abandone toda dualidad y que evite borrar las diferencias? ¿Podemos imaginar una ética ambiental que parta desde el cuerpo, el universo sensible y los contactos? Aún no sabemos todo el poder que tiene un cuerpo cuando se sabe cómo un cuerpo que habita entre otros cuerpos.

Published: July 2020

Antibiotics are the most commonly used medicines in healthcare facilities globally; and they are often misused, especially in developing countries. Periodic assessment of antibiotic prescribing practices is essential to improve prescribing standards and ensure rational use. A cross-sectional, retrospective evaluation of antibiotic prescribing in public secondary and tertiary hospitals in Nasarawa State, Nigeria was carried out. A total of 2800 case sheets of patients who accessed the hospitals under review during the period 2008-2018 were randomly sampled and evaluated. Prescribing indicators of World Health Organization (WHO) and Strengthening Pharmaceutical System/United States Agency for International Development (SPS/USAID) were evaluated and compared with published standards for each of the indicators to identify irrational antibiotic use. Percentage of hospitalization with one or more antimicrobials prescribed was 75.6%. Average number of antimicrobials prescribed per hospitalization in which antibiotics were used was 1.75±0.66. Percentage of antibiotic prescribed consistent with hospital formulary was 100.0%. Average duration of prescribed antimicrobial treatment was 5.57±2.42 days. Percentage of antimicrobials prescribed by generic name was 45.8%. Percentage of injectable antibiotic used was 36.4%. Percentage of antimicrobials prescribed from the national essential medicine list was 85.7%. Average encounter with antibiotic was 0.82±0.2. Many of the prescribing indicators deviated from the WHO or SPS/USAID optimal values; and thus, were predictors of irrational antibiotic prescribing. Continuous education and re-training of prescribers in public hospitals in Nasarawa State to comply with approved standards of prescribing should be emphasized in to ensure rational antibiotic use.

Published: July 2020

Liver is a vital organ present in vertebrates, which has a wide range of functions including aiding of digestion, detoxification and protein biosynthesis. But the ability of the liver to perform these functions can be compromised by numerous substances it is daily exposed to, including certain medicinal agents which when taken in over doses. Liver damage, just like many other diseased conditions can lead to oxidative stress, especially when the body’s antioxidant system is overwhelmed by the free radicals thus generated. A major component of this antioxidant system are the natural antioxidant enzymes superoxide dismutase and catalase manufactured in the body, which provide an important defense against free radicals usually generated in diseased conditions. Most synthetic anti-hepatotoxicity drugs available present serious side effects and are generally out of reach of the common man. Consequently, the effect of administration of aqueous extract of Anacardium occidentale stem bark on the activities of superoxide dismutase and catalase in some tissues of acetaminophen-induced hepatotoxic rats was investigated. There was a significant (p < 0.05) reduction in the activities of superoxide dismutase and catalase in the serum, liver, kidney and heart of the hepatotoxic rats. However, treatment of hepatotoxic rats with aqueous extract of Anacardium occidentale stem bark led to a significant (p < 0.05) increase in the activities of superoxide dismutase and catalase in the serum, liver, kidney and heart of acetaminophen-induced hepatotoxic rats.

Published: July 2020

Patient satisfaction is considered one of the preferred outcomes in health care as it is directly related to the re-use of health services as well as the success and sustainability of the health care facility. The purpose of this study was to examine and analyze the effect of the quality of services rendered by medical personnel on patient loyalty via the mediating influence of patient satisfaction. The study was designed using a cross-sectional questionnaire to collect data. 2372 outpatients were selected by simple random sampling. The data analysis method employed to test the hypotheses was the Structural Equation Modeling (SEM). The results showed that the quality of service rendered by the medical personnel has a positive association with patient satisfaction. Again, the higher the level of patient satisfaction, the higher the level of patient loyalty to medical services. Finally, the results of the indirect test supported the hypothesis that the quality of service of medical personnel has a positive effect on patient loyalty via the mediating influence of patient satisfaction.

Determinants of Credit Risk in the Banking Sector of Ghana: A Panel Co-integration Approach
Authors: Appiah Thomas , Bisiw Frank
Published: July 2020

The economic development of any nation hinges on the health of its financial system. In recent years, the health of the Ghanaian Banking sector has been affected severely as a result of high levels of non-performing loans (NPLs), which has been identified as a major threat to the overall profitability and survival of banks. To minimize the impact of NPLs on the financial sector, key stakeholders such as the government, bank officials and regulators are working hard in that regard. However, any policy response aimed at dealing with the high rate of non-performing loans first requires the understanding of the underlying determinants of NPLs. Against this backdrop, this paper apply panel co-integration techniques to investigate the determinants of credit risk (NPLs) in the banking sector of Ghana.  We use NPL as a proxy to measure credit risk and assess how it is influenced by macroeconomic and bank-specific factors. A balanced panel data of 16 universal banks in Ghana from 2010 to 2016 has been analyzed using Panel co-integration techniques such as Fully Modified Ordinary Least Squares (FMOLS) and Dynamic Ordinary Least Squares (DOLS). Our result shows that growth in the economy, measured by Gross Domestic Product (GDP) has significant influence on the NPLs of banks in the long-run. The results further revealed that capital adequacy, profitability and liquidity of banks are significant predictors of NPLs. However, our results suggest that bank size, inflation and interest rate have statistically insignificant influence on the NPLs of Ghanaian banks. The study recommend, among others, that whereas it is important for government and policymakers to work to improve macroeconomic outcomes, banks should also improve their capital adequacy, profitability, and efficiency position as these bank-specific interventions could significantly improve credit quality and minimize NPLs.

Authors: Ngasop Ndjiya , David Asnang , Djalo Haman
Published: July 2020

The transit of reactive power through the electric transport lines due to the inductive loads, creates problems of instabilities on the electrical networks. Transport networks are increasingly vulnerable to instability of voltage due to industrialization and/or population growth. The managers of these networks are therefore seeking effective solutions to these problems. STATCOM is one of the devices of the family of shunt FACTS used for reactive energy compensation. It generally offers better features compared other FACTS devices and conventional reactive compensation devices. This work aims to apply the STATCOM controlled by the current control method by hysteresis bands for the maintenance of the voltage in an electric transport network. The transport network is modeled as a transport line in MATLAB/SIMULINK and its characteristics are compared to the system without STATCOM.

The global trend is to minimize losses by using by-products from slaughterhouses as part of sustainable food production, both for human and animal consumption. Another growing trend is the development of pet feed with properties beneficial to the consumer's health. Another trend is the development of feeds with beneficial properties for the health of animals. Thus, the objective of this study was to use mechanically separated pork meat and by-products (trachea) to produce a pet snack containing the encapsulated probiotic yeast Saccharomyces boulardii. The experimental design followed in three main stages: 1) development of a pet pork snack (trachea snack); 2) microencapsulation of the probiotic and insertion in the pet snack; 3) Shelf life evaluation and palatability of the pet snack. S. boulardii was microencapsulated by extrusion technique and remained viable after 120 days of shelf life. The acceptability index of the probiotic pet snack was 77.8%.  We concluded that S. boulardii provides beneficial probiotics characteristics to pet snack whose composition has high levels of protein (57.50%). Thus, the novel pet product has a good appeal to the functional products market.

The investigation was conducted at the Olericulture Division, Bangladesh Agricultural Research Institute and the laboratory work was done at Vegetable Research Technology Section, Institute of Food Science and Technology, Bangladesh Council of Scientific and Industrial Research, Dhaka, Bangladesh during 2019-20 with ten types (Six- OP, four- Hybrid) of eggplant cultivar viz., BARI Begun-4, BARI Begun-6, BARI Begun- 8, BARI Begun-10, BARI Hybrid Begun-2, BARI Hybrid Begun-4, SM233, SM275, Hybrid 5x216 and Hybrid 21x11 to study the nutritional composition and its human health benefit. Eggplant is ranked amongst the most top ten vegetables that provide the healthiest food with low calories and also contain high phenolic contents that are helpful in radical absorbing capacity. Each vegetable contains a unique amount of various nutrients that are strongly linked with the protection of different health diseases. There were no significant differences among the six OP and four hybrid cultivars regarding yield. Fruit yield was more or less the same but the main differences were in fruit size and color as well as fruit shape. We got the moisture content (91.39-94.87%, crude fiber (1.01-2.48%), ash (0.37-0.62%), protein  (0.85-1.54%), fat  (0.02-0.4%), carbohydrate  (4.27-6.63%), energy (19.59-32.1Kcal), sugar (0.48-1.38%), ascorbic acid (6.57-17.21 mg 100g-1), anthocyanin (6.31-78.51 mgC3GE 100g-1). Significant amount of mineral were present in eggplant cultivars viz., K (122.38-162.27mg 100g-1), Na (4.06-8.51 mg 100g-1),  Ca (26.62-48.33 mg 100g-1), P (14.45-23.45 mg 100g-1), Mg (15.42-24.8 mg 100g-1), Fe (0.91-5.0mg 100g-1), Zn (0.22-0.57mg 100g-1), Mn (0.25-0.41mg 100g-1) and Cu (0.10-0.16mg 100g-1). These nutritional amounts will able to provide a significant amount of nutrition to the human body for the proper growth. These compounds were found helpful in the cure of various diseases like cancer, anti-inflammatory, anti-asthmatic, anti-platelet hypo-lipidemic, and hypotensive, etc. Today most modern scientific techniques are available to cure different various health problems but still majority of the population across the globe depends upon the vegetables sources nutritious food.

Irrational antibiotics use has added to the escalation of antibiotics resistance, especially among hospitalized patients on prolonged urethral catheterization, a significant risk factor for urinary tract infection and urosepsis. Extended-spectrum β-lactamases are transferable plasmid-mediated resistance mechanism orchestrated majorly by Enterobacteriaceae, which confer resistance to β- lactam antibiotics and other classes of antibiotics. This work was aimed at determining the molecular characteristics of uropathogenic Escherichia coli and Klebsiella spp involved in urinary tract infections among patients on prolonged urethral catheterization in two major tertiary hospitals in Lagos. One hundred and one samples were collected from participants in Lagos University Teaching Hospital and 68 Army Reference Hospital Yaba, between November 2015 and May 2016. The mean age of the participants was 49.04± 8.8years. Single, non -repeat aseptically aspirated urine specimens from the catheter ports were obtained from consenting participants and processed immediately. Bacterial species were isolated and characterized by conventional methods. Antibiotics susceptibility testing was done using a modified Kirby Bauer method. Further analysis was done by Polymerase Chain Reaction amplification aimed to detect bla SHV, bla TEM, and bla CTX-M resistance genes.  Isolates were considered significant if there were up to 104 CFU/ml in symptomatic participants and ≥105 CFU/ml in asymptomatic participants with analyzed. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 16.0 (Inc., Chicago 111). Forty (39.6 %) males and 61 (60.4 %) female participants’ catheter urines were sampled, with male to female ratio of 1:1.5. Fifty-nine (58.4%) out of 101 samples had significant growth, while 32 (54.2%) of these were lactose fermenters.  Of the 32 lactose fermenters, 26 were identified as E. coli and Klebsiella spp, while 23 (88.5%) of these 26 (identified as E. coli and Klebsiella spp) were ESBL producers carrying ESBL gene(s) and revealed various degrees of antibiotics resistance. We conclude by discussing the epidemiological importance of improving the infection control practices and antibiotics stewardship program as central dogma to controlling antibiotics resistance in hospitals.

Over the years, Moore prosthesis has been described as a good option in the treatment of femoral neck fracture. Its main disadvantages are about femoral fixation and the acetabular erosion. Because of less cost, it still be used improperly and provide a large number of failures. Improper placement of the Moore prosthesis provide biomechanical disturbances of the arthroplasty. The insufficient of residual femoral neck length or the insufficient of metaphyseal fill are associated with the failure of the Moore arthroplasty. The aim of our study is to report and evaluate intraoperative findings and difficulties while we were convert failed aseptic Moore hemiarthroplasty into cemented total hip arthroplasty.

Published: July 2020

The fall problem affects approximately one third of people aged over 65 years. Falls and fall-related injuries are one of the major causes of morbidity and mortality in the elderly population. Since many years, research activities have been targeted towards the development of technological solutions for the automatic detection and notification of falls. Among them, wearable based systems offer the advantage of being available ideally everywhere and cost-effective in terms of economy and computational burden. However, their use poses different challenges, from acceptability to battery usage. The choice of the communication technology, in particular, plays a fundamental role in the realization of a suitable solution, able to meet the target users’ needs. In this paper, we present a fall detection system, based on a pair of instrumented shoes. They communicate the alarming events to a supervising system through the LoRa LPWAN technology, without the need of a portable gateway. Experimental results demonstrate the effectiveness of the chosen communication technology and fall detection reliability.
Performance of Various Electrical Resistivity Configurations for Detecting Buried Tunnels Using 2D Electrical Resistivity Tomography Modelling
Authors: Ahmed Hassan Asem
Published: July 2020

This work aims to evaluate performance of 2D electrical resistivity modelling technique for detecting buried tunnels using various electrode configurations. A synthetic resistivity model was designed to explore the capability of Wenner, Wenner- Schlumberger, Dipole-Dipole, Pole-Dipole and Pole-Pole electrode configurations for detecting buried tunnels at different noise levels. 2D forward modelling (RES2DMOD) and 2D inversion (RES2DINV) software were implemented using blocky L1 norm optimization method. The results showed that the modelled tunnel can clearly be detected at 0% noise level due to the high resistivity contrast between the synthetic tunnel and the surrounding host materials. At 0-30% noise levels, the results indicated that dipole-dipole and Wenner- Schlumberger in the second order perform better than other configurations. This can be attributed to the characteristics features and sensitivity of these configurations for resolving the subsurface resistivity changes. It is suggested that these configurations are more suitable for detecting the buried structures. The results also showed that the inversion artifacts caused by high noise levels may smear the resistivity signature of the burred targets for particular configurations. Thus, obtaining high quality data ensures reliable resistivity interpretations. The study demonstrated the usefulness of the 2D numerical modelling for planning of electrical resistivity surveys.

Background

Immune checkpoint inhibitors have changed the paradigm of cancer treatment; however, non-invasive biomarkers of response are still needed to identify candidates for non-responders. We aimed to investigate whether immunotherapy [18F]FDG PET radiomics signature (iRADIOMICS) predicts response of metastatic non-small-cell lung cancer (NSCLC) patients to pembrolizumab better than the current clinical standards.

Patients and methods

Thirty patients receiving pembrolizumab were scanned with [18F]FDG PET/CT at baseline, month 1 and 4. Associations of six robust primary tumour radiomics features with overall survival were analysed with Mann-Whitney U-test (MWU), Cox proportional hazards regression analysis, and ROC curve analysis. iRADIOMICS was constructed using univariate and multivariate logistic models of the most promising feature(s). Its predictive power was compared to PD-L1 tumour proportion score (TPS) and iRECIST using ROC curve analysis. Prediction accuracies were assessed with 5-fold cross validation.

Results

The most predictive were baseline radiomics features, e.g. Small Run Emphasis (MWU, p = 0.001; hazard ratio = 0.46, p = 0.007; AUC = 0.85 (95% CI 0.69–1.00)). Multivariate iRADIOMICS was found superior to the current standards in terms of predictive power and timewise with the following AUC (95% CI) and accuracy (standard deviation): iRADIOMICS (baseline), 0.90 (0.78–1.00), 78% (18%); PD-L1 TPS (baseline), 0.60 (0.37–0.83), 53% (18%); iRECIST (month 1), 0.79 (0.62–0.95), 76% (16%); iRECIST (month 4), 0.86 (0.72–1.00), 76% (17%).

Conclusions

Multivariate iRADIOMICS was identified as a promising imaging biomarker, which could improve management of metastatic NSCLC patients treated with pembrolizumab. The predicted non-responders could be offered other treatment options to improve their overall survival.
Retrogression of Orthopyroxene-bearing Gneiss of Iboropa Akoko, Southwestern Nigeria
Authors: Oziegbe E.J. , Olarewaju V.O. , Ocan O.O. , Costin G.
Published: July 2020

In this article, we report the mineral chemistry and petrographic features of charnockitic exposure of Iboropa within Precambrian Basement Complex of Nigeria. The mineral assemblages are pyroxene, plagioclase, biotite, hornblende, alkali feldspars, microperthite, quartz and ilmenite, with apatite occurring as accessory mineral. Apatite occurs in abundance as euhedral crystals. Orthopyroxene observed is strongly pleochroic and has numerous microfractures, and it is hypersthene (En45Fs54Wo1) with low TiO2 and MnO, having extremely low percentage of CaO. Hypersthene is mantled by a complex corona of amphibole, and the amphibole is hornblende with a chemical formula: (K,Na)(Ca,Fe)2 (Fe,Mg,Al,Ti)5(Al,Si)8O22(OH)2. Plagioclase occurs as inclusions in both pyroxene and biotite. Biotite has high concentration of TiO2 and extremely low CaO. The opaque mineral observed is ilmenite and it is concentrated around hypersthene and amphibole. Rare earth element (REE) displays negative Eu anomaly with enrichment of light REE over heavy REE. Amphiboles surrounding orthopyroxene are evidences of retrograde reactions and are formed at the expense of orthopyroxene reacting with plagioclase and quartz in the presence of fluid. The relationship between the mineral assemblages suggests the retrogression of the gneiss that might be as a result of rehydration process, and it is a transition from granulite facies to amphibolite facies during a retrogressive form of metamorphism.
The American Roots of Social Epidemiology and its Transnational Circulation. From the African-American Hypertension Enigma to the WHO’s Recommendations
Authors: Arminjon Mathieu
Published: July 2020

In 2008, the Commission on Social Determinants of Health at the World Health Organisation published a report demonstrating the existence of a socio-economic gradient for health. Though health inequalities had been apparent since at least the 19th century, the report introduced a bio-psycho-social aetiological model that was absent from 19th century social medicine, as well as from former WHO documents. To bio-psycho-social epidemiologists stress associated with social status is the main cause of morbidity and death.

Here I begin by noting that the history social epidemiologists have written for their fi eld tends to inscribe their work in continuity with 19th century social medicine. This contributes towards minimizing the epistemological and contextual transformations that led bio-psycho-social epidemiology to initiate a profound transformation in international health policy. Adopting an epistemological and transnational perspective, I fi rstly argue that bio-psycho-social epidemiology emerged from René Dubos’ historical and epistemological critique of the foundation of 19th century social medicine. I secondly show how the political and epistemological research program elaborated by Dubos developed in the US context, which was characterized both by a growing concern for chronic diseases and for racial inequalities.

Finally, I show that through its transnational circulation in the United Kingdom, bio-psycho-social epidemiology was “de-racialized”. This step was a prerequisite for its aetiological model to be integrated into international public health strategies and to transform them.

Criminal Law in Indonesia is currently experiencing a renewal that includes formal criminal, material criminal and its implementation, it can be seen from the matter of Draft Law of the Criminal Code currently being discussed in the House of Representatives, is no exception about the criminal penalty for drug abuse which is now very threatening, many opinions of experts who argued that criminal confinement / imprisonment for narcotics abusers is not epektif because it can not cure and make a deterrent user. The regulation on the implementation of this rehabilitation was previously arranged through the Supreme Court Circular Number 07 Year 2009 to engage drug addicts in rehabilitation centers, with the aim that rehabilitation can be a punishment that heals the psyche and the minds of narcotics abusers who have been damaged due to the narcotics. Rehabilitation efforts for narcotics addicts and victims of narcotics abuse have not been found in the history of Islamic law development or Islamic criminal law, so this discussion should get further attention from the aspects of Islamic law (Maqasid As-Syari'ah) or Islamic criminal law

ABSTRACT

Sitophilus zeamais M. is a storage pest that attacks corn kernels in the storage. Pest control strategies in storage which are often carried out are chemicals, namely insecticides in the form of fumigants. One of them is using plant-based insecticides. Babadotan is a plant that can be used as a botanical insecticide. This research aimed to obtain an effective dose of babadotan flour towards the mortality of S. zeamais pest. This research was conducted at the Plant Pest Laboratory, Faculty of Agriculture, Riau University from March to May 2019. The research was conducted experimentally using a completely randomized design (CRD) with 6 treatments and 4 replications. Treatment given was babadotan flour with the following dosage: Babadotan flour dose 0 g.100 g-1 corn kernels,          2 g.100 g-1 corn kernels, 4 g.100 g-1 corn kernels, 6 g.100 g-1 corn kernels, 8 g.100 g-1 corn kernels, and 10 g.100 g-1 corn kernels. Dose 10 g.100 g-1 babadotan flour corn kernels is an effective dose to control Sitophilus zeamais which can cause total mortality of 82.5% with an initial death of 79,75 hours after application and Lethal time 50 254 hours after application. Application of babadotan flour with a dose of 10 g.100 g-1 corn kernels produced the lowest percentage of corn seed shrinking at 9,55% and resulted in the least individual increase of 4,75 tails.

We present a supercomputer-driven pipeline for in-silico drug discovery using enhanced sampling molecular dynamics (MD) and ensemble docking. We also describe preliminary results obtained for 23 systems involving eight protein targets of the proteome of SARS CoV-2. THe MD performed is temperature replica-exchange enhanced sampling, making use of the massively parallel supercomputing on the SUMMIT supercomputer at Oak Ridge National Laboratory, with which more than 1ms of enhanced sampling MD can be generated per day. We have ensemble docked repurposing databases to ten configurations of each of the 23 SARS CoV-2 systems using AutoDock Vina. We also demonstrate that using Autodock-GPU on SUMMIT, it is possible to perform exhaustive docking of one billion compounds in under 24 hours. Finally, we discuss preliminary results and planned improvements to the pipeline, including the use of quantum mechanical (QM), machine learning, and AI methods to cluster MD trajectories and rescore docking poses.

Monomers derived from renewable feedstocks have emerged as a novel sustainable alternative to petrochemical polymers. One of the biomass derived polymers that is recently gaining attention for food packaging applications is poly(ethylene furanoate) (PEF). However, PEF is not biodegradable and its end-of-life options must be considered in order to avoid contributing to the accumulation of plastic waste. In this paper, after analyzing the suitability of PEF for packaging applications using an industrially relevant film-processing method, the chemical glycolysis of PEF was investigated using a thermally stable acid-base organocatalyst. After succesfully deconstructing the PEF films into bis(2-hydroxyethyl)-furan-2,5-dicarboxylate (BHEF), the obtained BHEF was used to resynthesize PEF using the same organocatalyst to sucessfully generate a biopolymer with similar chemical and thermal properties to virgin PEF following a closed-loop cycle according to the Circular Economy principles.

As is well known, the thermally activated delayed fluorescence (TADF) is always generated from charge-transfer (CT) excited states in electron-donor (D) – electron-acceptor (A) systems. Here, a novel design strategy is proposed for realizing TADF from a locally excited (LE) state through controlling the intersystem crossing (ISC) and reverse intersystem crossing (RISC) processes between the LE singlet and higher triplet CT states. Based on the strategy, a boron difluoride derivative is theoretically predicted to emit TADF from the LE state, whose radiative decay rate constant is much larger kr (S1 →S0 )=1.12 * 108 s -1 , two orders of magnitude larger than those of common TADF systems. And its lifetimes of the prompt and delayed fluorescence are experimentally validated to be 0.44 ns and 0.7 μs, respectively. This work is a breakthrough in the understanding of TADF and opens a new avenue for extending the TADF materials.

Published: July 2020

The ongoing search to contain and control the spread of COVID-19 disease focuses on discovering drugs or vaccines that can play an essential role in treating this contagious disease. This paper focuses on natural compounds that can play a vital role in the treatment of Covid-19. The study spans over the chemicals that have the potential to bind with the key residues of type II Transmembrane Protease Serine (TMPRSS2). TMPRSS2 can be termed as the catalyst that cleaves the spike glycoproteins of Sars-Cov-2, which causes the replication and spread of virus inside the human body by facilitating virus-cell fusions. Drugs like Camostat Mesylate, Aprotinin, and Rimantadine have been proposed as potential inhibitors of TMPRSS2. After screening large sets of phytochemicals and flavonoids extracted from plants, potential compounds have been tested, and a set of most effective and suitable compounds are chosen for further studies. These selected compounds are further analyzed in terms of binding with key residues as well as high binding affinity with TMPRSS2. The in silico analysis of possible chemical compounds is carried out by using docking, screening analysis, Molecular Dynamics, and Electrostatic Potential Simulations. Chemicals extracted from different plants are comparatively analyzed with drugs like Aprotinin, Camostat Mesylate, and Rimantadine.

Triboluminescent compounds that generate emission of light in response to mechanical stimulus are promising targets in the development of “smart materials” and damage sensors. Among triboluminescent metal complexes, rare-earth europium and terbium complexes are most widely used, while there is no systematic data on more readily available and inexpensive Cu complexes. We report a new family of photoluminescent Cu-NHC complexes that show bright triboluminescence (TL) in the crystal state visible in ambient indoor light under air. Moreover, when these complexes are blended into amorphous polymer films even at small concentrations, TL is easily observed. Observation of TL in polymer films overcomes the limitation of using crystals and opens up possibilities for the development of mechanoresponsive coatings and materials based on inexpensive metals such as Cu. Our results may also have implications for the understanding of the TL effect’s origin in polymer films.
