Compost enriched with effective microorganism and Bordeaux mixture on ginger bacterial wilt (Ralstonia solanaceurum) Epidemics in southwestern, Ethiopia
Authors: Guji Merga Jibat , Asfaw Mulukan
Published: April 2022

Ginger is one of the most widely cultivated spice grown in various cropping systems and locations throughout the southwestern Ethiopia. Bacterial wilt, caused by Ralstonia solanacearum, is one of the serious diseases of ginger in Ethiopia. Field experiments were conducted during 2019 and 2020 to assess effects of soil amendments on bacterial wilt development and epidemics at Tepi, southwestern Ethiopia. Three soil amendments practices: compost, effective microorganisms and Bordeaux mixture alone and in integration were evaluated. Treatments were arranged in a randomized complete block design with three replications. Compost at the rate of 7 ton/ha enriched with effective microorganisms and Bordeaux mixture treatment significantly reduced ginger bacterial wilt incidence, area under disease progress curve and disease progress rate. This treatment reduced bacterial wilt mean incidence up to 21.08 % as compared to untreated control plot. Compost at the rate of 7 ton/ha also slowed down epidemic progression of bacterial wilt and significantly reduced the disease parameters when effective microorganisms and Bordeaux mixture were integrated. The overall results indicated that integrated compost enriched with effective microorganisms and Bordeaux mixture was effective to slow down the epidemics of ginger bacterial wilt and sustain ginger production and productivity. Hence, integrated compost enriched with effective microorganisms and Bordeaux mixture along with other crop management systems are recommended to improve ginger production and productivity at southwestern Ethiopia and other similar ecologies.

Klein Four-Group as the Factor Group for Elucidating RS-Stereoisomerism of Cubane Derivatives. The Factor-Group Method for Type-Itemized Enumeration of Stereoisograms
Authors: Fujita Shinsaku
Published: April 2022

Van't Hoff's way (asymmetry, stereogenicity) and Le Bel's way (dissymmetry, chirality) are compared from the viewpoint of two ways for investigating organic stereochemistry, where cubane derivatives of the point group are selected as probes. For emphasizing Le Bel's way, combinatorial enumerations of 3D structures under point groups are first discussed to develop Fujita's proligand method and Fujita's USCI approach. The foundations of these enumerations are applied to support synthetic studies of stereoisomers for emphasizing van't Hoff's way after the proposal of Fujita's stereoisogram approach based on RS-stereoisomeric groups, e.g., . Importance of the proligand-promolecule model is emphasized in enumerations under point groups (Fujita's proligand method and Fujita's USCI approach) as well as in enumerations of RS-stereoisomeric groups (Fujita's stereoisogram approach). After the five types (type I to type V) of stereoisograms are classified into three categories (i.e., Category 1 (types I/IV), Category 2 (types II/III/V), and the co-existence case), the half-size-subgroup method and the factor-group method have been developed for type-itemized enumerations of stereoisograms. Type-V stereoisograms for characterizing "extended pseudoasymmetry" are discussed by assigning their configuration numbers and CA-descriptors.

Published: April 2022

Establishing dynamical models to characterize the relation of different chemical compositions is an important topic in chemistry and mathematics. However, a lot of dynamical models are merely concerned with the integer-order dynamical models. The report on fractional-order chemical dynamical systems is quite few. In this current article, based on the earlier publications, we establish a new fractional-order coupled Oregonator model incorporating time delay. A set of sufficient conditions which ensure the stability and the onset of Hopf bifurcation of fractional-order coupled Oregonator model incorporating time delay are derived by regarding the time delay as bifurcation parameter. The exploration manifests that time delay has a vital influence on stabilizing system and controlling bifurcation of the investigated fractional-order coupled Oregonator model. At last, Matlab simulation results are adequately displayed to corroborate the derived theoretical achievements.
Absolutely Complex Balanced Kinetic Systems
Authors:   University of the Philippines, Jose Editha C. , Talabis Dylan Antonio SJ. , Mendoza Eduardo R.
Published: April 2022

A complex balanced kinetic system is absolutely complex balanced (ACB) if every positive equilibrium is complex balanced. Two results on absolute complex balancing were foundational for modern chemical reaction network theory (CRNT): in 1972, M. Feinberg proved that any deficiency zero complex balanced system is absolutely complex balanced. In the same year, F. Horn and R. Jackson showed that the (full) converse of the result is not true: any complex balanced mass action system, regardless of its deficiency, is absolutely complex balanced. In this paper, we present initial results on the extension of the Horn and Jackson ACB Theorem. In particular, we focus on other kinetic systems with positive deficiency where complex balancing implies absolute complex balancing. While doing so, we found out that complex balanced power law reactant determined kinetic systems (PL-RDK) systems are not ACB. In our search for necessary and sufficient conditions for complex balanced systems to be absolutely complex balanced, we came across the so-called CLP systems (complex balanced systems with a desired "log parametrization" property). It is shown that complex balanced systems with bi-LP property are absolutely complex balanced. For non-CLP systems, we discuss novel methods for finding sufficient conditions for ACB in kinetic systems containing non-CLP systems: decompositions, the Positive Function Factor (PFF) and the Coset Intersection Count (CIC) and their application to poly-PL and Hill-type systems.

In this paper we report on some mathematical investigations of the chemical process for the hydrogenolysis of glycerol over a heterogeneous metal catalyst. The main interest of this process is related to the fact that glycerol is produced as a by-product in the production of biodiesel in huge amounts that are expected to exceed the projected demands. This makes the sustainability of biodiesel production depend on the conversion of the glycerol into useful products hence it is a desirable goal to have effective conversion methods. A reaction model from literature is used to derive a system of ordinary differential equations (ODE) which is then analysed using methods from qualitative analysis of ODEs. Numerical solutions of the system are simulated to try and find out the solution’s behaviour in the chemistry point of view. It was found that all solutions of the model converge to some stable limit point in a 2-dimensional plane in the positive cone of the phase space, and the limit point depends on the values of rate constants as well as on the hydrogen to glycerol initial ratios. Even though the results are based on a specific kinetic model, it is hoped that they may help in providing tools for better understanding and description of the reaction.

Nanofibras de celulosa extraídas a partir de rastrojo de piña y raquis de palma africana, fueron sometidas a funcionalización con ácido cólico. La nanocelulosa se caracterizó por espectroscopia infrarroja, microscopía electrónica de barrido y ángulo de contacto. Posteriormente se evaluó mediante análisis estadísticos, la influencia de dicha funcionalización en la adsorción del cromo de una disolución de Cr2(SO4)3. De lo anterior se determinó que existe una mayor adsorción del metal si se utilizan nanofibras sin funcionalizar extraídas a partir de rastrojo de piña, mientras que para las fibras extraídas a partir de raquis de palma africana la funcionalización con ácido cólico genera mejores cargas de adsorción. Finalmente se realizaron curvas de adsorción y se acoplaron a 3 modelos de isotermas de adsorción, de las cuales se establece que el modelo de Sips describe de mejor manera el comportamiento de los datos experimentales, con cargas máximas de 8,605 mg Cr/g NCF (nanocelulosa fibrillar) para la nanocelulosa sin funcionalizar extraída a partir de rastrojo de piña y 5,638 mg Cr/g NCF para la nanocelulosa funcionalizada extraída a partir de raquis de palma africana.

Palm dates are among the most highly cultivated and consumed fruits in Kuwait and other Arabian Gulf countries. However, data on the nutritional content of Kuwaiti date fruits remain scarce. The purpose of the current study was to determine the nutritional composition and biochemical characteristics of five date palm fruit varieties at the Khalal stage grown in Kuwait. Samples of five different cultivars (Berhi (samples from 2 different locations), Ikhlas, Saamaran, and Khanizi) grown in Kuwait were analyzed for energy, protein, carbohydrates, sugars, antioxidants, and micro-minerals. Varieties studied had high energy values ranging between 351.63 kcal/100g and 368.35 kcal/100g. They were rich in potassium (4450-7128mg/100g), with significant amounts of calcium (287.8-469.1mg/100g), magnesium (130.3 -294.5 mg/100g), sodium (70.7-123.3 mg/100g), iron (2.45-3.2 mg/100g) and manganese (0.7-1.55 mg/100g). Gallic (19.97-5.47 mg/100g), chlorogenic (0-0.712mg/100 g), and ascorbic (0.624-0.875 g/1mg) acids were the main antioxidants. The data indicate that the Kuwaiti date fruit is a rich source of essential nutrients making it an important local product that requires further investigations for its nutritional properties and industrial utilization prospects.

The relevance of detecting aquifer characterization and aquifer potential has risen with the application of well logging techniques as the demand for water has increased. Apart from pumping data, 16 geophysical well logs (resistivity, gamma ray, self-potential, and nuclear logs) are utilized to achieve the main goal of estimating petrophysical parameters (porosity (∅), effective porosity (∅𝑒𝑓𝑓), hydraulic conductivity (k), permeability (K) and shale volume (𝑉𝑠ℎ)) of the Apollonia (Eocene fractured limestone aquifer), Upper and Lower Bahariya (Nubian sandstone aquifer) formations. The findings show that the Eocene fractured limestone aquifer has a carbonate in soft chalk with high K and ∅ as well as high k of 4974.39 mD at well ST-188 (a highly productive aquifer), whereas the Lower Bahariya formation is mostly fine to medium-grained sandstone and clay, suggesting that it formed in shallow marine environments with low K. On the other hand, Upper Bahariya was noted that having poor sand succession. As results shown, K of the most examined wells ranges from 2609.69 to 1486.812 mD at ST-258 and ST-38 wells respectively. The study appears that 𝑉𝑠ℎ, along with ∅ and K features, is regarded as an important attribute in aquifer evaluation where, estimated 𝑉𝑠ℎ over the studied area is ranges between 5.96% and 31.7% at ST-48 and WBS1 wells respectively. Overall, this study provides an important insight into the importance of evaluating groundwater aquifers over time to help in making decisions to save and protect groundwater aquifers in the future.

The economical fabrication of one-dimensional dielectric reflectors using the hybrid sol-gel spin coating process is significant compared to sophisticated chemical and physical vapor deposition techniques. In this work, we opted for alternate layers of TiO2 and SiO2 films to fabricate near-infrared dielectric reflectors owing to their high refractive index contrast and easy tunability of the reflection window in the desired spectral range. X-ray diffraction (XRD) studies of the monolayer TiO2 and SiO2 confirmed the existence of anatase-TiO2 and amorphous-SiO2 phases, respectively. Spectroscopic ellipsometry investigation of TiO2 and SiO2 films revealed the refractive indices of 2.6 and 1.5, respectively. The field-emission scanning electron microscopy (FESEM) analyses evidenced the fabrication of 2.5 stacks/bilayers of TiO2/SiO2 (TiO2/SiO2)2.5S. The reflectance measurement demonstrated 100% reflection in the near-infrared region with its center wavelength of 833 nm. In addition, we have examined the water contact angle of various samples using the sessile drop technique, and 2.5 stacks-based reflector showed its lowest contact angle of 29.3o, which suggests its anti-fogging and self-cleaning applications.

Authors: G. M. Kadam
Published: April 2022

Experimental data for preformulation study is significant to develop a stable and safe drug product and forms the basis of preliminary information required to develop and design the final formulation. The experience, knowledge of drug substance components and ingredients planned to use in formulation, plays an important role in designing the preformulation studies. Co-ordination between the departments such as mainly analytical research and formulation research in conducting these studiesi.e., interdepartmental co-ordination, exchange of information and knowledge to perform research experimentation is necessary, to understand the knowledge of the complete lifecycle of the drug product. Analytical chemistry deals with methods of analysis developed and planned to use for content determination of related substances/impurities leads to get noteworthyinformation required to develop stable formulation and to determine the stability of the drug product. The usage of multiple instrumental techniques for identification, estimation and characterization techniques are essential to get the results of the research studies. The cGMP and GLP requirements should be fulfilled and followed as per the respective country specific regulatory guidelines.
Mechanisms of Mitigating Chloride-Induced Stress Corrosion Cracking of Austenitic Steels by Laser Shock Peening
Authors: Yoo Yongchul , Yan Xueliang , Wang Fei , Zhu Qiuchi , Lu Yongfeng , Cui Bai
Published: April 2022

This study investigates the effect of laser shock peening (LSP) on the chloride-induced stress corrosion cracking (SCC) of 304 austenitic steels. LSP can induce a high compressive residual stress to a depth of 700 µm and plastic deformation structures of dislocations, deformation twins, and stacking faults. Constant-load SCC tests in MgCl2 solution suggested that LSP can retard the crack initiation and slow the crack growth. LSP-treated subsurface layers experience ductile fracture while the central regions exhibit intergranular SCC. The LSP-induced deformation structures may impede dislocation slips, while the LSP-induced compressive residual stress can lessen the stress intensity factor of crack tips and decrease the local stress for film rupture.

Introduction

Encephalopathy and stroke in COVID-19 patients have been repeatedly reported. Previous reports indicate that SARS-CoV-2 infection is associated with a significantly escalated risk of ischemic stroke, especially with potentially cryptogenic stroke. Encephalopathy is also present in Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL). Definitive diagnosis of CADASIL is based on sequencing the NOTCH3 gene. Primary pathology is the accumulation of abnormal transmembrane deposits on vascular smooth muscle cells in the brain and other organs.

Material and methods

Genome of the patient was sequenced with the average depth of coverage 32,7x and mapped to the reference genome GRCh38. The whole genome sequencing (WGS) approach identified heterozygous missense variant NOTCH3 in the exon 8. Targeted Sanger sequencing was done to confirm the presence of the variant, and to examine the closest relatives. Beside the patient, all family members were unaffected, the variant appeared de novo.

Results

Identified variant was not reported in the GnomAD v.3 and 1000 Genomes, nor in polymorphism database dbSNP. No clinical information was available in ClinVar. The only information regarding variants in the same amino acid position (Cs440Ser and Cys440Gly) from LOVD database were reported by Markus et al. They were found in 2 individuals affected with CADASIL and interpreted as pathogenic on the basis of symptoms and familial cosegregation.
Beside the patient, all family members were unaffected, the variant appeared de novo.

Conclusions

The simultaneous COVID-19 infection could probably provoke an exacerbation of a previously asymptomatic CADASIL patient and could lead to an acute ischemic multi-infarct encephalopathy.
A better Chinese man
Authors: Ang Sylvia
Published: April 2022

This chapter details how digital media interact with and shape Chinese
men’s sense of identities. Drawing on the author’s text chats, phone chats
and meet-ups with Chinese migrant men initiated on the mobile media app
WeChat and on internet forums frequented by Singaporean-Chinese men, it
analyses the fluid meanings of being a Chinese man. This chapter analyses
low-wage Chinese migrant men’s feelings of displacement and how they are
positioned by Singaporean-Chinese men into the bottom rung of a hierarchy
of Chinese masculinities. Yet low-wage Chinese migrant men do not submit
entirely to their perceived subordinate status and reimagine ethnicity, gender
and class to reposition themselves as better people than the host society.
Métodos em fatores humanos no planejamento de sistemas de sinalização para pedestres: Legible London como estudo de caso
Authors: Barros Aline de Camargo
Published: April 2022

A compreensão profunda do sujeito e seu ambiente é essencial para projetos de sinalização eficientes, principalmente durante a etapa inicial de pré-design ou planejamento. Deve-se compreender as vivências e costumes dos diferentes personagens urbanos e as especificidades socioculturais do cotidiano, junto às transformações digitais e a criação de sistemas híbridos. Diante deste cenário, os métodos em ergonomia e fatores humanos – em especial, os cognitivos, comportamentais e macro ergonômicos – ampliam a análise e levantamento dos dados na fase de planejamento de um sistema de sinalização informativo no ambiente urbano, garantindo resultados mais significativos ao final do processo. Este artigo pretende analisar e avaliar os métodos em fatores humanos aplicados no pré-design do projeto Legible London, um estudo de caso reconhecido internacionalmente no desenvolvimento de uma cidade mais legível e com novas tecnologias.
Representação Gráfica das expressões faciais de personagens antropomorfos 3D na comunicação de Emoções
Authors: Shimizu Lorena , Martins de Oliveira Spinosa Rodrigo , Castro Andreo Marcelo
Published: April 2022

O antropomorfismo é um recurso estético extremamente importante no cinema de animação que atribui características humanas a objetos, eventos, animais ou personagens de fantasia não-humanos. Sua difusão se deu pela facilidade que esta técnica permite de comunicar e criar empatia entre o público e o personagem, principalmente por meio das expressões faciais. Porém, apesar de importantes, grande parte dos estudos relacionados às técnicas construtivas desses recursos estão presentes na literatura das Histórias em Quadrinhos ou na documentação de processos de animação bidimensional (2D). Poucas são as fontes que abordam de forma estrutural a configuração das expressões faciais em personagens antropomorfos tridimensionais (3D), fator este que traria considerável contribuição, em virtude da grande difusão das tecnologias de representação 3D nos projetos cinematográficos. Desta forma, o presente artigo objetiva entender e documentar como são criadas as expressões faciais em personagens antropomorfos utilizando técnicas de modelagem 3D, podendo assim servir de roteiro construtivo para os profissionais que trabalham com animação ou Design de personagens. A metodologia adotada foi a pesquisa bibliográfica, abordando princípios da expressão facial humana e fundamentos da modelagem 3D, seguida de um estudo de caso sobre a configuração básica das malhas 3D para gerar as expressões faciais de personagens do Studio Disney.

El incremento acelerado de la demanda de energía debido al desarrollo y aumento demográfico involucra crecientes exigencias de recursos. La diversidad de tipologías de la metrópolis referente a recursos, solicitudes, condiciones arquitectónicas, infraestructura o densidad, hace importante un estudio específico. En el trabajo se identifican ciertos recursos referentes al proceso de organización que permitirían seleccionar la tecnología más correcta para el Cantón Santa Ana de la provincia de Manabí, donde se valoraron los recursos del medio que se sustentan para hacer inversiones aprovechando otro tipo de energías limpias, debido a que recurso es el componente de más monumental preponderancia, seguido de las condiciones económicas; en contraparte se detecta que puntos del medio ambiente como cambio climático, eutrofización o acidificación, son los menos incidentes rápido de elegir tecnologías. La investigación es de tipo descriptiva que recoge el análisis de varios trabajos de investigación relacionados con el marco regulatorio energético, la GD y las fuentes renovables de energía. Para ello se empleó el método Desk research, que consiste en una técnica que utiliza datos existentes y disponibles públicamente, incluye material publicado en documentos de investigación y otros materiales de este tipo. Se aplicó el método inductivo-deductivo para obtener los resultados partiendo del razonamiento lógico mediante el análisis de la información disponible, para establecer los elementos conceptuales a partir de la situación real y conocer el estado actual de las leyes y normas que rigen la gestión energética en el Ecuador y llegar a conclusiones concretas sobre el tema estudiado. Se concluye que las regulaciones sobre las energías renovables en el Ecuador instituyen los requisitos básicos y las situaciones preferentes para la producción de esta variedad de energías no convencionales en el espacio eléctrico ecuatoriano.
