Published: February 2023

Biogas is treated as a prominent renewable source in the world for mitigating fuel crises in developing countries. Using biogas technology toxic waste can be handled with an anaerobic process helping to generate natural fertilizers. So, it is a major concern for the researchers to find the proper solution by selecting a suitable renewable energy source in the present world. Biogas is treated as a type of biofuel that can be obtained from the fermentation of organic waste. The main goal of this research is to show the potential of a biogas generator in terms of cow dung, vegetable waste, kitchen waste, and poultry to generate biogas. The produced biogas from the decomposition of the organic waste can be utilized in electric power generation to fulfill the power demand of a house. From the analysis, it is seen that cow dung is the most powerful waste for the generation of biogas in comparison to other types of waste. The calculation shows that cow dung is almost 86.75 % more efficient than the kitchen waste and 44.49 % more efficient than the vegetable waste. And some practical data of a biogas power plant has been included to show the potentiality of biogas in the present world.

Aim of the Study:The aim of the study was to evaluate and compare the efficacy of the 3-dimensional titanium miniplates against conventional titanium miniplates in the management of mandibular fractures. Materials and Method:This study included 20 cases of either trauma, reconstructive or orthognathic surgery in which internal fixation is indicated. Patients were assigned to any one of the two equal groups randomly. Group A consisted of 10 patients treated by 3-dimensional titanium miniplates and group B consisted of 10 patients treated by conventional titanium miniplates. Intra-operative parameter included operating time of both the groups. Postoperative clinical examination was carried out on the 1st, 2nd, 3rd, 4th, 6th weeks and the 3rd postoperative month. Postoperative clinical evaluation included assessment of pain, stability, infection, bite force, wound dehiscence. The results of two groups were compared statistically. Results:A statistically significant difference was found in the operating time which was less in group A as compared to group B (p = 0.001). The bite forces recorded on 1st postoperative week were more in group A as compared to group B and were found to be statistically significant at incisor region (p=0.012), right canine region (p=0.014), left canine region (p=0.001), right premolar region (p=0.013) and left premolar region (p=0.046). No significant difference was found in other clinical parameters. Conclusion:Due to simultaneous stabilization at superior and inferior borders, operating time was relatively less. It provides three-dimensional stability at the fracture site. 3-dimensional miniplate seems to be an easy alternative to conventional miniplates.

The wildlife conservation approach that insists on making forests free from human activity brings a drastic change for communities residing inside the forest risking their very existence. This ethnographic study of pastoralists, cohabitating with Asiatic lions inside the wildlife-protected area, explored the influence of restrictions imposed on their lives. Data was collected through participant observations, informal discussions, and in-depth interviews. Ordered and social arena maps as described in the situational analysis approach by Adele Clarke, were used for analysis. The social arenas of State, Temporary migration, and Market were found to shape the lives of the Maldharis. Their life after the declaration of the protected area was characterized by economic insecurity, lost identities, loss of networks, dignity, and honor. The multiple and multifold vulnerabilities of the marginalized Maldharis, who made forests their homes for generations, warrant an integrated approach towards conservation.

The objective of this study is to characterize the risk of flooding in the Agro zone 5 of Benin. The methodological approach can be summarized in several stages: the determination of the various climatic extreme indices (Rx1day, R95p and R99p) obtained by the rain data from the stations of Bohicon, Save and Parakou, then the analysis of the occurrence of these indices is made by the frequency analysis method, and finally the mapping of areas at risk of flooding is carried out based on the geological funds, the Digital Terrain Model (DTM), the land use units and rainfall data at the various stations covering the study area. The identification of areas at risk of flooding is governed by the combination of thematic maps based on the multi-criteria analysis method. The vulnerability map is obtained thanks to three physical factors which are: the slope, the drainage density and the geological units. The hazard map is obtained by combining land cover and rain fields. The results of this research reveal that in the Agro zone 5 of Benin, daily maximum rainfall of 60.68mm and 126.43mm has a probability of 0.5% and 0.2% of occurring for return periods of 2 and 5 years. The combination of the vulnerability and flood risk map shows that high and very high flood risk areas cover 24% of the total area of the study area.

The present work is interested in the mathematical and numerical modeling of the effects of different parameters such as the angle of the cone, the length of the cone, the hot source radius, and the hot source length on thermal plume flow in interaction with its surrounding. The behavior of the guided thermal plume flow can give us more knowledge about the control parameters of different applications relevant to the environment and industry. This study investigates the thermal plume in interaction with its surrounding environment. To determine the control parameters that influence this flow we must study at the beginning mathematically and numerically the studied flow thru a natural convection flow generated by a circular hot source at the entrance of a vertical cone (Figure 1). In this work, the flow is natural convection, turbulent, steady, two-dimensional, incompressible flow. Numerical results are obtained using CFD analysis based on mathematical modeling of the flow and ANSYS-FLUENT software. The introduction of the hot source with a different radius causes an important change in the flow structure. The profiles show a very strong gradient in the temperature in the zone near the plume source for a specific cone angle. The comparison of different profiles indicates the optimized control parameters of the flow.

Baitulmal is a national treasury institution that is responsible for ensuring that the welfare of Muslims is taken care of without sidelining other citizens who live in an Islamic country. Therefore, its management needs to be carried out with full trust, integrity and accountability so that its aim can be achieved which can be used as a platform to raise the message of Islam. However, in the Islamic inheritance system, non-Muslimsareprevented from receiving Muslim inheritance even if they have family ties. Inheritance without Muslim heirs causes this inheritance to be handed over to Baitulmal. In light of that, the objective of this study is to identify baitulmal interaction with regards to the claims of non-Muslim family memberson the estate of deceased converts. This qualitative study via content analysis gathered data and information through document analysis and interviews. The collected data were then analyzed using a descriptive approach. The results of the study found that Baitulmal applied harmonious interaction in meeting the claim of a converts inheritance by non-Muslim heirsin Malaysia. Thus, in the context of being used as a reference, this study can contribute to unravel the misunderstanding among non-Muslim heirsregarding the role of Baitulmal in meeting their demands on the inheritance left by converts and can also be used as a form of dawah to them to understand Islam.

As a Brazilian Amazon fruit, bacuri tree (Platonia insignis Mart.) has been pointed out as an important species to the sustainable management and development of the Amazon region. However, since it is not yet domesticated, techniques regarding its propagation are still incipient. This study aimed to evaluate the genetic control of traits related to in vitro establishment of Platonia insignis accessions from different regions of the Maranhão state, Brazil. Immature fruits were collected over different sites for explants obtention. The in vitro responsiveness of the genotypes was evaluated by assessing the percentage of explant oxidation (OXI), pinkish-colored defense structures (PCDS), callogenesis (CAL), radicle (ROOT) and shoot forming (SHOOT). Callus was classified according to its callogenic potential, namely as: globular-friable, with higher embryogenic potential; undefined structure [cell mass], with lower embryogenic potential; and white spongy-like callus, absent of embryogenic potential. The estimates of genetic parameters were accomplished via REML (Restricted Maximum Likelihood)/BLUP (Best Unbiased Linear Prediction) mixed model. The outputs showed high genetic variability within the studied population. Additionally, accessions AC.7, AC.2, AC.1, AC.6, and AC.8 showed as more efficient by considering characteristics related to the in vitro regeneration, thereby presenting a superior callogenesis ability; lower susceptibility to oxidation; and higher capacity for root and shoot formation. This was the first study to investigate the relationship among genetic parameters and selecting accessions of P. insignis for in vitro regeneration, thus providing support for studies related to micropropagation and domestication of this species

The QTLSD7-1/Rc is a pleiotropic locus that controls seed dormancy and pericarp color in rice. DNA sequence variation in promoter region, exon1, and intron 1 in wild rice from Thailand and Laos, weedy rice accessions from Thailand, as well as cultivated rice were investigated using re-sequencing DNA technique. For promoter region, three types of DNA variation were observed including variation in number of nucleotide (T)n (n=9,10,11), five SNPs and 19-bp indel. For coding region exon 1, no DNA sequence variation was observed. For non-coding region intron1, weedy rice had the 10-bp insertion in the region, but there was the deletion in wild rice. In addition, deletion of 34-bp in intron1 was observed in all wild rice accessions examined, while weedy rice had the 34-bp insertion. Haplotype analysis of weedy rice indicated that the pairwise nucleotide diversity parameter, Pi (ℼ) and the level of the Watterson estimator (Өw) in the DNA sequences were 0.00401 and 0.0048, respectively. This finding enhances knowledge of the DNA sequence

Published: February 2023

O consumo de bebidas alcoólicas e produtos de tabaco é mais frequente entre universitários, quando comparado à população geral. Especialmente em se tratando de universitários da área da saúde, como os estudantes em Enfermagem. Destaca-se o fato de ser uma formação em que o principal fio condutor é o cuidado humano, logo, consumir substâncias potencialmente danosas ao próprio organismo e, ao mesmo tempo, ter a tarefa de ser um agente de cuidados, prevenção e promoção em saúde, pode configurar um grande desafio. O objetivo do estudo foi investigar as representações sociais que universitários de Enfermagem possuem acerca do consumo de bebidas alcoólicas e produtos de tabaco, compreendendo as razões pelas quais esta prática ocorre. Participaram do estudo 28 alunos dos últimos semestres da graduação em Enfermagem de uma universidade privada na cidade de São Paulo- Brasil. Para a coleta de dados, utilizou-se um questionário de caracterização da amostra e uma questão-caso ilustrando um contexto de ingestão das substâncias avaliadas. Os dados foram analisados a partir da metodologia do Discurso do Sujeito Coletivo de Lefèvre e Lefèvre, utilizando-se alguns recursos da psicanálise para interpretação dos resultados. Os resultados apontam que as substâncias mais utilizadas foram as bebidas alcoólicas, seguido pelo narguilé. Aspectos de socialização, válvula de escape e prazer se mostraram bastante associados à ingestão das substâncias, portanto, conclui-se que estes não devem ser desprezados e tampouco descontextualizados na criação de políticas para redução do consumo.
The Emerging Role of Sodium-glucose Cotransporter 2 Inhibitors in Heart
Failure

Published: February 2023

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are a relatively novel drug class that most cardiologists
are becoming familiar with. By contrasting glucose reabsorption in the proximal convoluted tubule of
the nephron, SGLT2 inhibition results in glycosuria with improved glycemic control. Although originally introduced
as anti-diabetic medications, the cardiovascular effects of SGLT2i have progressively emerged, leading
them to become one of the four pillars for the treatment of heart failure with reduced ejection fraction (HFrEF)
according to the 2021 guidelines from the European Society of Cardiology. Also, two recent randomized trials
have demonstrated SGLT2i as the first compounds with proven prognostic impact in heart failure with preserved
ejection fraction (HFpEF), setting a milestone in the treatment for this condition. While the exact pathogenic
mechanisms mediating the substantial reduction in cardiovascular death and heart failure (HF) hospitalizations
are still controversial, there is growing clinical evidence on the efficacy and safety of SGLT2i in various
subsets of patients with HF. As known, heart failure is a complex and heterogeneous clinical syndrome with a
magnitude of phenotypes and a variety of underlying hemodynamic and physiological aspects which cannot be
fully incorporated into the traditional left ventricular ejection fraction based classification adopted in clinical
trials. The aim of this review is to provide an overview of the cardiovascular benefits and indications of
SGLT2i across different HF patterns and to highlight current gaps in knowledge that should be addressed by future
research.

Published: February 2023

Background:

Breast cancer is the most common malignant tumour in women. Radical mastectomy with postoperative radiotherapy is now the standard treatment
for locally advanced breast cancer. Intensity-modulated radiotherapy (IMRT) has now been developed, which employs linear accelerators to
deliver precise radiation to a tumour while minimizing the dose to surrounding normal tissue. It significantly improves the efficacy of breast cancer
treatment. However, there are still some flaws that must be addressed.

Objective:

To assess the clinical application of the three-dimensional (3D)-printed chest wall conformal device for breast cancer patients who need to be
treated by chest wall intensity modulated radiotherapy (IMRT) after radical mastectomy.

Methods:

The 24 patients were divided into three groups. During a computed tomography (CT) scan, patients in the study group were fixed by a 3D-printed
chest wall conformal device, nothing in control group A, and a traditional 1-cm thick silica gel compensatory pad on the chest wall in control group
B. The parameters of mean Dmax, Dmean, D2%, D50%, D98%, the conformity index (CI), and the homogeneity index (HI) of the planning target
volume (PTV) are compared.

Results:

The study group had the best dose uniformity (HI = 0.092) and the highest conformation (CI = 0.97), the worst in control group A (HI = 0.304, CI
= 0.84). The mean Dmax, Dmean, and D2% of the study group were lower than control groups A and B (p<0.05). The mean D50% was higher
than control group B (p<0.05), while the mean D98% was higher than control groups A and B (p<0.05). The mean Dmax, Dmean, D2%, and HI of
control group A were higher than control group B (p<0.05), whereas the mean D98% and CI were lower than control group B (p<0.05).

Conclusion:

By improving the efficacy of postoperative radiotherapy for breast cancer, using 3D-printed chest wall conformal devices may greatly improve the
accuracy of repeating position fixation, increase the dose on the skin surface of the chest wall, optimise the dose distribution of the target area, and
thus further reduce tumour recurrence and prolong patients' survival.

Authors: Zhang Yu , Zhang Ping
Published: February 2023

Background:

In this study, ampicillin sodium fluorescent carbon quantum dots were
prepared by one-step hydrothermal method with ampicillin sodium as the carbon source and urea
as the nitrogen source.

Methods:

The structure of CQDs were characterized by UV-Vis and fluorescence spectrophotometer.
The pH, reaction time and ionic strength of phenol detected by N-CQDs were optimized.
The optimum experimental conditions were 40 μL ampicillin sodium N-CQDs, 2 mL
buffer solution with pH 8.0, and the reaction time was 6 min.

Results:

Through the detection of fluorescence spectrophotometry, p-nitrophenol had obvious
fluorescence quenching phenomenon on ampicillin sodium N-CQDs, and the detection limit was
75 nM. It was used in the standard addition experiment of actual samples, and the recovery rates
were more than 85%.

Conclusion:

Therefore, the N-CQDs could be used as fluorescent probe to analyze the content
of p-nitrophenol in the actual environment.
A Greener Synthetic Approach to Tetrazoles via Multicomponent Reactions
Authors: Ray Devalina
Published: February 2023

The synthesis of heterocyclic compounds has drawn considerable attention in the scientific community due to their existence in the majority of medicinal & pharmaceutically important compounds as well as natural products. Among them, the remarkable existence of tetrazoles has been realized in several commercially available drugs. In this regard, various synthetic protocols to access tetrazoles have been developed to address the efficiency and environmental impacts in terms of minimization of the steps, elevating yields, and conducting environmentally benign and sustainable chemistry. The management and detrimental environmental impact of waste has been recognised as a consistent concern, along with the costs associated with its disposal. Among various approaches to minimise unwanted materials from a process, one of the best alternatives is to perform a reaction in the absence of excess chemical reagents and catalysts. Other options include the reactions affected by the application of heat, light, sound, or electrolysis. The multicomponent reactions (MCR) display a unique approach establishing a step forward toward clean, step and atom-economical chemical synthesis. Most of them utilize the required substrates, eliminating the stoichiometric use of reagents, reducing the possibility of forming unwanted side products. The present review displays the concepts of MCR in the synthesis and functionalization of tetrazole, which contributes to green and sustainable chemistry.
Need and Possibilities of Phytocompounds against SARS-CoV-2: Recent
Advances in COVID-19 Therapy
Authors: R. Pradeep Kumar
Published: February 2023

Efforts have been made during the past two years to find out novel and effective drugs
against SARS-CoV-2. Plants have become a source for the development of novel and improved
medications against viruses due to the advancement of biomedical technologies and pharmacological
evaluations. Phytocompounds including flavonoids, phenolics, alkaloids, lignans, terpenoids and
tannins have been demonstrated to have antiviral properties, particularly against SARS CoV-2. The
present review discusses information on the potential antiviral traditional medicines, medicinally
important plants, their extracts and the specific bioactive compounds present in such plants along
with their mode of action. It also gives an insight regarding the limitations in exploring medicinal
plants for phytocompound antimicrobial drug discovery, and suggests novel and prospective strategies
considering the fact that they are naturally occurring and relatively less harmful with a view to
combating the present pandemic and the ones that may happen in the future.
Numerical analysis of failure modeling in clinching process chain simulation
Authors: Bielak C.
Published: February 2023

Abstract. The application of the mechanical joining process clinching allows the assembly of different sheet metal materials with a wide range of material thickness configurations, which is of interest for lightweight multi-material structures. In order to be able to predict the clinched joint properties as a function of the individual manufacturing steps, current studies focus on numerical modeling of the entire clinching process chain. It is essential to be able to take into account the influence of the joining process-induced damage on the load-bearing capacity of the joint during the loading phase. This study presents a numerical damage accumulation in the clinching process based on an implemented Hosford-Coulomb failure model using a 3D clinching process model applied on the aluminum alloy EN AW-6014 in temper T4. A correspondence of the experimentally determined failure location with the element of the highest numerically determined damage accumulation is shown. Moreover, the experimentally determined failure behavior is predicted to be in agreement in the numerical loading simulation with transferred pre-damage from the process simulation.

Published: February 2023

La globalización está ligada al nivel de integración futuro de los países en Cadenas Globales de Valor (cgv). Utilizando el enfoque de cgv se analizó el efecto de la gobernanza en los mecanismos de aprendizaje sobre la actualización (upgrading) responsable. Se aplicaron 17 entrevistas con actores clave del sector aguacatero mexicano durante mayo y agosto del 2021, para obtener información de los principales acuerdos entre compradores, clientes y requisitos para participar en los mercados globales. La información recabada se complementó con bases de datos de organismos gubernamentales y se realizó un análisis gráfico, de nubes de palabras y estadística descriptiva. Se encontró que la gobernanza global es modular, pero al interior de la cadena fue de mercado, modular y jerárquica, basado en las características de las transacciones. Los aprendizajes por imitación están presentes en gobernanzas de mercado y jerárquica, pero en la primera es de baja tecnología y de alta en la segunda. Se concluye que al participar en cgv los conocimientos de normas y estándares permiten aumentar el volumen de ventas y acumular capital, pero no garantizan aprendizajes para lograr mejoras productivas o funcionales. La responsabilidad como práctica de la gobernanza es variable entre eslabones, depende de capacidades y voluntades individuales y colectivas, la ausencia de instrumentos validados para responsabilizar empresas dificulta su aplicación, ya que estos instrumentos deben resolver problemas reales y no solo aportar conocimiento científico.
Design Principles in mHealth Interventions for Sustainable Health Behavior Changes: Protocol for a Systematic Review
Authors: Yang Lin , Kuang Angela , Xu Claire , Shewchuk Brittany , Singh Shaminder , Quan Hude , Zeng Yong
Published: February 2023

Background

In recent years, mHealth has increasingly been used to deliver behavioral interventions for disease prevention and self-management. Computing power in mHealth tools can provide unique functions beyond conventional interventions in provisioning personalized behavior change recommendations and delivering them in real time, supported by dialogue systems. However, design principles to incorporate these features in mHealth interventions have not been systematically evaluated.

Objective

The goal of this review is to identify best practices for the design of mHealth interventions targeting diet, physical activity, and sedentary behavior. We aim to identify and summarize the design characteristics of current mHealth tools with a focus on the following features: (1) personalization, (2) real-time functions, and (3) deliverable resources.

Methods

We will conduct a systematic search of electronic databases, including MEDLINE, CINAHL, Embase, PsycINFO, and Web of Science for studies published since 2010. First, we will use keywords that combine mHealth, interventions, chronic disease prevention, and self-management. Second, we will use keywords that cover diet, physical activity, and sedentary behavior. Literature found in the first and second steps will be combined. Finally, we will use keywords for personalization and real-time functions to limit the results to interventions that have reported these design features. We expect to perform narrative syntheses for each of the 3 target design features. Study quality will be evaluated using the Risk of Bias 2 assessment tool.

Results

We have conducted a preliminary search of existing systematic reviews and review protocols on mHealth-supported behavior change interventions. We have identified several reviews that aimed to evaluate the efficacy of mHealth behavior change interventions in a range of populations, evaluate methodologies for assessing mHealth behavior change randomized trials, and assess the diversity of behavior change techniques and theories in mHealth interventions. However, syntheses on the unique features of mHealth intervention design are absent in the literature.

Conclusions

Our findings will provide a basis for developing best practices for designing mHealth tools for sustainable behavior change.
