Published: August 2020

Various strategies have been proposed to engineer the band gap of metal halide perovskite nanocrystals (NCs) while preserving their structure and composition and thus ensuring spectral stability of the emission color. An aspect that has only been marginally investigated is how the type of surface passivation influences the structural/color stability of AMX3 perovskite NCs composed of two different M2+ cations. Here, we report the synthesis of blue-emitting Cs-oleate capped CsCdxPb1-xBr3 NCs, which exhibit a cubic perovskite phase containing also Cd-rich domains of Ruddlesden-Popper phases (RP- phases). The RP domains spontaneously transforms into pure orthorhombic perovskite ones upon NC ageing and the emission color of the NCs shifts from blue to green over days. On the other hand, post-synthesis ligand exchange with various Cs-carboxylate or ammonium bromide salts, right after NC synthesis, provides monocrystalline NCs with cubic phase, highlighting the metastability of the RP domains. When the NCs are treated with Cs-carboxylates (including Cs-oleate), most of the Cd2+ ions are expelled from the NCs, the NCs’ phase evolves from cubic to orthorhombic and their emission color changes from blue to green. Instead, when the NCs are coated with ammonium bromides, the loss of Cd2+ ions is suppressed and the NCs tend to retain their blue emission (both in colloidal dispersions and in electroluminescent devices), as well as their cubic phase, over time. The improved compositional and structural stability in these latter cases is ascribed to the saturation of surface vacancies, which may act as channels for the expulsion of Cd2+ ions from the NCs.

Published: August 2020

Many molecular simulation methods use force fields to help model and simulate molecules and their behavior in various environments. Force fields are sets of functions and parameters used to calculate the potential energy of a chemical system as a function of the atomic coordinates. Despite the widespread use of force fields, their inadequacies are often thought to contribute to systematic errors in molecular simulations. Furthermore, different force fields tend to give varying results on the same systems with the same simulation settings. Here, we present a pipeline for comparing the geometries of small molecule conformers. We aimed to identify molecules or chemistries that are particularly informative for future force field development because they display inconsistencies between force fields. We applied our pipeline to a subset of the eMolecules database, and highlighted molecules that appear to be parameterized inconsistently across different force fields. We then identified over-represented functional groups in these molecule sets. The molecules and moieties identified by this pipeline may be particularly helpful for future force field parameterization.
Stochastic Thermodynamics Analysis of Ultrafast AgAu Nanoshell Dynamics in the Nonlinear Response Regime

Published: August 2020

The understanding of relaxation dynamics of metallic nanoshells is important for a range of nanotechnological applications. In this work, we present a combined experimental-theoretical study of the relaxation dynamics of AgAu nanoshells. This was investigated using ultrafast pump-probe experiments resonant with the surface plasmon of the nanoshells, as well as via atomistic molecular dynamics simulations of relaxation and temperature-jump (DT-jump) processes. Both techniques were then discussed and complemented using a non-equilibrium statistical mechanical model. Data collected at low energies were consistent with our previously reported work and allowed the characterization of intrinsic electron-phonon coupling times (EPCT) and of the overall relaxation dynamics in terms of a two-temperature model. Data at intermediate and higher energies, in turn, showed a nonlinear dependence of EPCT as a function of the pump power, faster relaxation being observed at higher pump energies. In the limit of small DT-jumps, relaxation based on a two-temperature model is recovered, whereas in the limit of large DT-jumps, the relaxation becomes faster with increasing temperature change. The results reported here give insight on the ultrafast dynamics of AgAu nanoshells and might also be applied to other metallic systems, paving the way to the better understanding of relaxation dynamics of nanoparticles in general.
Evaluation of Anticonvulsant and Anti-oxidant Potentials of Basella Alba by Influencing the Brain Enzyme Levels in Laboratory Animals

Published: August 2020

Epilepsy and convulsions constitute a significant class of symptoms that are commonly seen in many neurological diseases. It is understood that there is an apparent alteration in the levels of the enzymes which present brain during epilepsy. Anti-oxidant drugs are known to elevate the protective enzyme levels in the body and restore them to ensure the proper functioning is done. But when the enzyme levels are not managed properly, they can cause further damage and deterioration of the tissue. Basella alba is one of such drugs, which is rich in anti-oxidant chemical constituents. Many researchers concluded that many components like vitamin A, C and flavonoids, polyphenols are being reported. In the study, Basella alba was investigated for effect on an anti-oxidant enzyme in the brain. The extracts showed a better activity and prevented the brain tissue damage from any oxidative free radical generation. The enzyme levels were healthy at the dose of 400mg/kg of extract.

Published: August 2020

This research aimed at analyzing the influence of e-learning service quality and academic engagement on academic achievement through student satisfaction as an intervening variable. Only students who had ever used e-learning service could be the research sample and 222 students were sampled using purposive sampling. The data were collected by distributing questionnaire to the research samples. The data were analyzed using path analysis technique. The result indicated that e-learning service quality, academic engagement, and student satisfaction had an influence on accounting students’ academic achievement. From this research finding, it was suggested that university lecturers keep on developing teaching and learning strategies which can improve students’ academic engagement since it has been proven that academic engagement has a dominant influence on students’ academic achievement.
Engineering of a Novel Anti-Dioxin Bacillus Subtilis Probiotic for Poultry Feed
Authors: Guo Keyi , Huang Alyssa , Lee Osanda
Published: August 2020

Introduction: Plastic waste incineration has increased dramatically in Asia, producing highly toxic by-products such as dioxins. The biomagnification and bioaccumulation of dioxins from the atmosphere to the soil, agriculture, feed, livestock, and finally to humans poses a serious concern for public and environmental health. This study aims to engineer a novel poultry feed additive for detoxification of poultry products.
Methods: The Bacillus subtilis feed probiotic will be created via insertion of a dioxin degradation system from Sphingomonas wittichii and thymine dependent biological containment system. This method is appropriate given that dioxin’s primary form of contact with humans is through ingestion. All experimentations will be done in triplicates and with appropriate control groups.
Results: For the experimental group (recombinant B. subtilis growing on PCDD- and PCDF-contaminated media), an increase in catechol is expected in comparison to the control groups. This will be quantified via liquid chromatography. In addition, a decrease in PCDD and PCDF levels will be expected and measured via mass spectrometry. It is postulated that the chickens will not undergo significant changes after intake of the probiotic in the animal trials. The laboratory observations in measuring biodegradation efficiency are expected to persist into animal trials.
Discussion: Although good combustion practice is the top method for removing dioxins, it is impractical in developing countries due to its costs. Therefore, recombinant bacterial chicken feed probiotic is the most cost effective in terms of removing dioxins from contaminated animal products despite its few limitations.
Conclusion: This study implicates a gap in literature in developing preventative measures for toxic plastic waste disposal by-products which could be mediated through increased research of the application of dioxin-degrading enzymes. Possibilities for further research include examination of dioxin impacted farm animals and the effects of B. subtilis as a probiotic.

Совокупный анализ данных использованных методов (хемосорбции, рентгеновской фотоэлектронной спектроскопии, электронной микроскопии, рентгенографии) показал, что причина десятикратной потери активности катализаторов в результате проведения реакции в мягких условиях (атмосферное давление, H2, 25 °C) — образование наноразмерной фазы графита. Это явление, обычное для высокотемпературных реакций, при низких температурах обнаружено впервые.

Authors: Sanjaya Joseph , Ayub Mewati
Published: August 2020

Deep convolutional neural networks (CNNs) have achieved remarkable results in two-dimensional (2D) image detection tasks. However, their high expression ability risks overfitting. Consequently, data augmentation techniques have been proposed to prevent overfitting while enriching datasets. In this paper, a Deep Learning system for accurate car model detection is proposed using the ResNet-152 network with a fully convolutional architecture. It is demonstrated that significant generalization gains in the learning process are attained by randomly generating augmented training data using several geometric transformations and pixel-wise changes, such as image cropping and image rotation. We evaluated data augmentation techniques by comparison with competitive data augmentation techniques such as mixup. Data augmented ResNet models achieve better results for accuracy metrics than baseline ResNet models with accuracy 82.6714% on Stanford Cars Dataset.
Modelo predictivo del riesgo de abandono escolar en educación media superior en México
Authors: Hernández-Jácquez Luis Fernando , Montes-Ramos Frine Virginia
Published: August 2020

Los índices nacionales en materia de abandono escolar o deserción en la educación media superior en México fluctúan entre 14.5 % y 16.5 %, y la investigación empírica sugiere que el abandono se encuentra mayormente asociado a la reprobación, y esta, a su vez, a cuestiones como la falta de autorregulación en el aprendizaje y a los hábitos de estudio. La presente investigación tuvo como objetivo el establecimiento de un modelo para predecir el riesgo de abandono escolar en estudiantes de nivel medio superior en México. Se desarrolló una investigación cuantitativa, no experimental y transversal. La variable independiente, que
fue el riesgo de abandono escolar, se valoró a través del Cuestionario de Abandono Escolar, mientras que las variables predictoras fueron los hábitos de estudio, la autorregulación del aprendizaje y los estilos de aprendizaje (por así convenir a la institución), valorados mediante el Cuestionario de Hábitos de Estudio, el Cuestionario de Estrategias de Aprendizaje y Motivación II (CEAM), y el Cuestionario Honey – Alonso de Estilos de  Aprendizaje (CHAEA). Para determinar la ecuación predictiva, se utilizó el modelo de regresión logística binaria, mediante el método “pasos hacia atrás de Wald”, con una muestra de 192 estudiantes del primer semestre de un bachillerato tecnológico agropecuario, en su mayoría con edades de entre 14 y 16 años. Se obtuvo un modelo que incluye las dimensiones de estrategias para la planificación del estudio y estrategias para la toma de apuntes, relacionadas con los hábitos de estudio; y autoeficacia para el aprendizaje, relacionada con la autorregulación, explicando el 37.0 % del fenómeno. Se concluye que con el establecimiento de mecanismos de predicción del riesgo de abandono escolar, se podrían mejorar o incrementar las dimensiones ya mencionadas, para reducir en cierta medida el riesgo de abandono escolar.

Prevention by utilizing medicinal plants can be used as an alternative treatment. This study aims to identify active antimicrobial substances and test the antimicrobial potential of traditional Balinese spices, namely Basa Selem, Basa Gede, Basa Wangen, Basa Bawang Jahe, and Basa Rajang against Salmonella sp bacteria in vitro. The True-experimental method with Posttest only-control design was used in this study, by intervening in the treatment group as well as the presence of positive and negative controls. The maceration method with 96% EtOH solvent was used to extract active substances and identify the levels of antimicrobial active substances. The TLC Spectrophotodensitometer instrument and the diffusion method (discs) were used to test antimicrobial potential. Data analysis was performed using the one-way ANOVA test. All five samples showed flavonoids, alkaloids, tannins, and phenols in qualitative tests. Based on quantitative test results of five samples, the highest compound content obtained in Basa Wangen (6.66 mg/ml of tannins), Basa Gede  (3.74 mg/ml of flavonoids), Basa Bawang Jahe (2.49 mg/ml of tannins), Basa Selem (2.87 mg/ml of tannin), and Basa Rajang (6.96 mg/ml of flavonoids). There are differences in the antimicrobial potential of various types of traditional Balinese spices against the growth of Salmonella sp in vitro (sig = 0.037). The traditional Balinese spices have the antimicrobial potential of the intermediate category with a range of inhibition (16-20 mm) based on the NCCLS standard.
Investigation of revers-transcriptase polymerase chain reaction values of patients with COVID-19 findings in lung computed tomography results
Authors: Osman Ozüdogru , Bolatli Gunes , Tas Fatih
Published: August 2020

It turned out that the cause of pneumonia cases that occurred in China was due to SARS-CoV-2. The aim is to compare chest computer tomography and Revers-Transcriptase Polymerase Chain Reaction methods used in the diagnosis of COVID-19 disease with each other and to evaluate this disease with risk factors.

The study was carried out on 66 patients. Epidemiological history, clinical symptoms, chest CT and RT-PCR results of the cases were examined. RT-PCR results of 1, 4, and 7 days were evaluated for each case with positive chest CT results. Thirty-seven of them were found to be positive on day 1, 5 of them were found to be positive on day 4, and 2 of them were found to be positive on day seven from 52 patients whose RT-PCR results were examined. In the remaining 8 cases, no positive findings were found. The most common findings are; cough (78.8%), fever (55.8%), and shortness of breath (28.8%). It was observed that 51.9% of the cases had chronic disease history and 50% of the patients using cigarettes had bilateral lung involvement in their CT results. Seven cases received intensive care support, 3 cases were intubated. Two of the intubated cases were exitus (3,8%). The positive results of RT-PCR were found to be negative in most of the cases which have positive chest CT; suggests that chest CT is more reliable in making a diagnosis.  Therefore, evaluating chest CT results with RT-PCR can be an appropriate alternative approach in the diagnosis and treatment of disease. However, in order to be fully diagnosed, the patient's history, chronic diseases, age, symptoms, imaging, blood, and test findings must all be considered as a whole.

Pemanfaatan proses elektrolisa air pada pengembangan penelitian di bidang energi hidrogen saat ini menjadi salah satu alternatif sumber bahan bakar air. Proses pemisahan moelekul air menjadi gas hidrogen dan oksigen menggunakan elektrolisa air, yaitu dengan mengalirkan litrik kepada larutan elektrolit (katalis NaCl dan air) melalui elektroda alumunium. Bahan bakar berupa gas hidrogen dan oksigen yang dihasilkan oleh proses ini akan digunakan untuk mengurangi konsumsi BBM. Sebanyak 4 tabung digunakan untuk perancangan elektroliser. Larutan maksimal pada masing-masing tabung adalah 500 ml air dan katalis NaCl 6 gram. Kestabilan proses elektrolisa diatur berdasarkan Itensitas air dalam tabung untuk memaksimalkan HHO yang dihasilkan.Dalam hal ini tentu dengan bantuan sensor yang selanjutnya data akan diolah oleh mikrokontroler Atmega8535, yang kemudian ditampilkan di LCD sebgai perintah untuk penggantian air. Bahan bakar air BBA dapat menghasilkan gas HHO dengan adanya arus dari spull motor yang mengalir pada dua eletroda dalam air sehingga terjadi proses elektrolisa dan mengasilkan gas hidrogen HHO yang kemudian masuk keruang bakar mesin dan mengurangi konsumsi BBM.

The purpose of this study was to determine the macroscopic and microscopic characteristics of endophytic bacteria that live in the root and leaf tissue of several wet habitat trees, such as: kayu marsegu (Anthocephalus cadamba), ketapang hutan (Terminalia copelandii) and kayu burung (Elaeocarpus ganitrus). This study shows that the results of microscopic identification of 20 samples of bacterial isolates, there are only 11 samples of endophytic bacteria that live in the root and leaf tissue of tree samples. Furthermore, based on microscopic identification with the Gram Staining Method, it was found that there were 17 samples of endophytic bacterial isolates categorized into gram-negative (-), namely: DM1, DM3, DM4, AM1, AM2, AM3, AM4, DKH2, DKH3, DKH4, AKH1, AKH2, AKB1, AKB2, AKB3, DKB3, and DKB4. While 3 other bacterial isolate samples were classified into gram-positive (+), namely: AKH3, AKH4, and AKB4. Based on observations with a microscope with 1000 times the magnification size, all bacteria isolates were categorized as a rounded bacterial group, and therefore they are classified as genera Monococcus, Staphylococcus, and Streptococcus. The study also found that all three genera of bacteria have the ability to live in root and leaf tissue, even though the tree habitat is in a long-wet condition.
