Fabrication of Dye-Sensitized Solar Cells (DSSC) Using Mg-Doped ZnO as Photoanode and Extract of Rose Myrtle (Rhodomyrtus tomentosa) as Natural Dye

A dye-sensitized solar cell (DSSC) device using Mg-doped Zn thin films as photoanode and fruit extract of rose myrtle (Rhodomyrtus tomentosa) as the natural dye was investigated. The effect of annealing temperature (400-550°C) on the films of photoanode was systematically studied using an X-ray diffractometer (XRD), UV-Visible Near Infrared (UV-Vis NIR) Spectrophotometer, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). XRD confirm that all sample has the wurtzite hexagonal with crystallite size of 25 nm. The SEM images reveal particles on the surface of the Mg-doped ZnO thin film of irregular shapes. Increasing the annealing temperature leads to a larger particle size and slightly increases bandgap energy. The dye sensitizer of extracted rose myrtle (Rhodomyrtus tomentosa) has a strong absorption at the visible light region. The maximum efficiency of the DSSC device is 3.53% with Mg-ZnO photoanode annealed at 500°C.
Efficacy of Different Dentin Posts for the Treatment of Primary Anterior Teeth (An In vitro study)

Introduction: Early childhood Caries is a distressing situation for patients and parents and pediatric dentists. Aim: current research was carried out to evaluate fracture resistance and bond strength for different types of dentin posts compared to fiber posts. Materials and Methods: This Current in-vitro study was conducted on 48 extracted primary incisors. Samples were split randomly into 4 groups of 12 for each group. Group-I (fiber posts 6mm length, 1.4mm diameter), Group-II (dentin posts 6mm length, 1.4 diameter), Group-III (dentin posts 8mm length, 1.4mm diameter), Group-IV (dentin posts 8mm length, 1.6mm diameter). Each group was further subdivided into two subgroups (6 for the Push-Out bond strength test and 6 for the fracture resistance test using Universal Testing Machine). Results: It was observed in the fracture resistance test that, Group III showed the highest fracture resistance means (140.678±11.98) followed by Group IV (131.38±7.03), Group-II (94.23±9.84), and finally Group-I that showed the lowest fracture resistance means (80.465±2.82). Push-Out bond strength test revealed that the highest mean value with Group-IV (8.653±1.49), followed by Group-II (6.08±2.25) and Group III (5.67±2.44) have no statistically significant difference between them, while the lowest mean value was for Group-I. Conclusions: Dentin posts showed increased fracture resistance and bond strength more than fiber posts. The use of dentin post as intra-canal retention in primary anterior teeth possesses the most important advantages over the fiber post. Therefore, biological dentin post is a successful alternative for fiber post. INTRODUCTION Crown damage of primary anterior teeth is a frequent issue in pediatrics dental clinics because of either early childhood caries (ECC) or trauma (1). ECC is a quickly progressing developing type of dental caries that occurs primarily in the cervical third of maxillary incisors till full damage of the crown. It principally affects the primary maxillary incisors shortly following the eruption of teeth and infects other primary teeth quickly causing early tooth loss (2). In primary teeth, gaining intracanal retention through posts is tricky due to that permanent teeth need to find a way for primary counterparts. To ensure well-timed eruption of permanent successors in normal undeflected places, the intracanal post would timely resorb way (3). DOI: 10.21608/dsu.2021. 58163.1059 Manuscript ID: DSU-2101-1059
Are Farmers Trapped in Hold-Up Relationships with their Contractors in the Supply Chain? The Case of Dairy Farmers and Feed Suppliers

Agricultural production is widely discussed in the context of imbalances in bargaining power in the food chain and farmers’ difficult position relative to their contractors. The paper attempts to explain the nature and reasons of the bargaining power imbalances that may lead to hold-up relationships in the farming sector in the light of the Transaction Costs Theory (TCT). In order to provide a certain focus, the theoretical discussion is illustrated by an empirical example of backward vertical relations between farmers and input (feed) suppliers. The article investigates the reasons for long-term and stable relationships between farmers and feed suppliers and whether these may be partly explained by an imbalance in bargaining power, trapping farmers in the specific monopolistic (hold-up) relations with their contractors.Overall, the picture that emerges from the analysis does not support the assumptions that farmers are experiencing a large imbalance in bargaining power with regard to their input contractors, and are trapped in a specific monopolistic (hold-up) relationship with them. Despite that there is no written contract between the farmers and their suppliers, relations are based on unwritten, privately enforced terms. The parties tend to respect the mutually agreed relationship rather than breaching it ex-post in order extract the holdup quasi-rents. In this case a binding written supply commitment may increase transaction costs, limit the freedom to change supplier and reduce the farmer’s bargaining power over the feed producer by adding additional inter-dependency.

EFFECT OF IN-OVO NANO-SELENIUM INJECTION ON HATCHABILITY, THYROID HORMONES AND HISTOLOGICAL CHANGES OF IMPROVED BALADI CHICKENS

The current study amid to study the effect of in ovo injection by SeNPs on chicks weight, hatchability, thyroid hormones (T3 and T4) and histological parameters at the first day of the experiment of improved Baladi chicken. A total number of 525 fertile improved Baladi eggs (Saso with Golden Montazah) with an average weight of 51.30g±0.81 were used. Before incubation, eggs were randomly divided into seven groups. The first group was non-injected eggs, considered as control(T1), the second group was injected into air sac with sterile water with volume of 0.1 ml/egg (T2), the third group was only punctured (T3) while the fourth (T4), fifth (T5) , sixth (T6) and seventh (T7) groups were injected into air sac with 0.1 ml sterile water containing 0.05, 0.075, 0.1 and 0.2 μg SeNPs respectively . The eggs were incubated at normal condition of incubation. Results obtained could be summarized as follows: 1Hatching weight was significantly (P≤0.05) increased in treated groups compared to the control groups. 2Hatchability of fertile eggs was significantly (P≤0.05) decreased by ovo injection with SeNPs as compared to the control. 3Plasma T3 and T4 at the first day of age was significantly (P≤0.05) increased by ovo injection with SeNPs as compared to the control. 4At hatch, there is no obvious histological difference in the studied organs such as liver, thymus, bursa and kidney except the thyroid gland in between the seven studied groups.
Production of Transgenic Cavendish Banana (Musa Acuminata L.) Resistant to Fungal Infection using Chitosan Nanoparticles

Cavendish bananas ʻGrand Nainʼ are commercially important cultivars. It belongs to the Cavendish subgroup of the AAA banana cultivar group. These cultivars face the problem of quick rotting due to infection with different phytopathogens. Gene transformation technique was used to improve the cultivar productivity and resistance to infection. Thionin genes (AT1G12660 and AT1G12663) were isolated from Arabidopsis thaliana. Thionin genes (thio-60 and thio-63) are antimicrobial genes producing antimicrobial proteins which inhibit fungal infection. These two thionin genes were integrated into the pEGAD vector. Then transformed into the tested banana cultivar via chitosan nanoparticles using the shoot tip culture technique. The chitosan nanoparticles are efficient, rapid and safe transformation technique. The resulted transgenic banana lines were partially resistant to infection by two different fungal species: Fusarium solani and Fusarium equiseti. These fungi cause rotting for the non-transgenic lines compared to the transgenic lines which resist the rotting infection due to the expressed inhibitory thionin protein. Transformation of thionin into the transgenic plants were confirmed by conventional PCR.
Demystifying Subjective Well‐Being of Academically At‐Risk Students: Case Study of a Chinese High School

Student subjective well‐being (SWB) is increasingly incorporated into today’s education policies and positive education movements. There is a growing interest in how well schools promote student well‐being, especially for disadvantaged students, e.g., the academically at‐risk, and which factors affect this process. This study investigates how teachers and academically at‐risk students perceive SWB and its influential precursors in a high school in China. The influential precursors in the present research were allocated into four dimensions, namely contextual factors, school factors, family factors, and individual factors. Via semi‐structured individual interviews with 12 teachers and 18 students for about one hour and content analysis of the interview data, the responses revealed that while students tended to have a superficial understanding of well‐being, traditional concepts about studying, blind filial piety, peer relations, and self‐efficacy were important factors shaping and influencing their SWB. These findings can inform the development of inclusive education policies concerning student SWB and the intervention and prevention systems of schools in both local and international contexts. Recommendations for organising lectures for parents and implementing programs providing instruction on SWB‐related skills for students are proposed to support academically at‐risk students, aiming to achieve the educational goal of success for all.

In this pilot case-control study, we examined microbial composition and inferred function in the saliva of patients after heart transplantation. Methods: Saliva samples were collected from 26 healthy adolescent and adult heart transplant patients and 27 healthy non-transplant controls. Bacterial DNA was isolated and the V3 and V4 regions of the 16S rRNA gene were sequenced. Measures of bacterial diversity and inferred function were calculated using the software packages DADA2, Phyloseq, QIIME, PICRUSt and STAMP. Results: Transplant patients were on average 51.6 ± 18.2 years of age and 8.6 ± 5.3 years post-transplant. Both alpha (p = 0.0009) and beta (p = 0.001) diversity differed significantly between the groups, and there were statistically significant changes (p < 0.01) in 101 individual functional pathways. Discussion: We conclude that the effects of chronic immunosuppression on bacterial composition and function in the oropharynx appear relatively subtle with no obvious ill effects on patient health. Full interpretation is limited by our lack of knowledge for many of the bacterial functional pathways.
MNN and LSTM-based Real-time State of Charge Estimation of Lithium-ion Batteries using a Vehicle Driving Simulator

Lithium-ion batteries (a type of secondary battery) are now used as a power source in many applications due to their high energy density, low self-discharge rates, and ability to store long-term energy. However, overcharging is inevitable due to frequent charging and discharging of these batteries. This may result in property damage caused by system shutdown, accident, or explosion. Therefore, reliable and efficient use requires accurate prediction of the battery state of charge (SOC). In this paper, a method of estimating SOC using vehicle simulator operation is proposed. After manufacturing the simulator for the battery discharge experiment, voltage, current, and dischargetime data were collected. The collected data was used as input parameters for multilayer neural network (MNN) and recurrent neural network–based long short-term memory (LSTM) to predict SOC of batteries and compare errors. In addition, discharge experiments and SOC estimates were performed in real time using the developed MNN and LSTM surrogate models. Keywords—Lithium-ion battery; state of charge; multilayer neural network; long short-term memory; vehicle driving simulator; real time
Hepatoprotective Effect and Potential Mechanism of Aqueous Extract from Phyllanthus emblica on Carbon-Tetrachloride-Induced Liver Fibrosis in Rats

Liver fibrosis is a pathological variation caused by almost all chronic liver injuries. As an edible and medicinal natural resource, Phyllanthus emblica (PE) has been reported to possess hepatoprotective, antioxidant, and anti-inflammatory activities and may have an ameliorating effect on hepatic fibrosis. To investigate the protective effect of the aqueous extract of PE (AEPE) against liver fibrosis and to uncover its related mechanisms, the chemical profile of AEPE was characterized by high performance liquid chromatography (HPLC) and sulfuric acid-phenol method. Ameliorative effects of different doses of AEPE were investigated in carbon-tetrachloride- (CCl4-) induced liver fibrosis rats by analyzing biochemical markers, morphologic pathology, and related proteins expression in liver tissue. The results indicated that AEPE (1.8, 3.6 g/kg) could significantly reduce levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), collagen IV (Col IV), type III precollagen (PCIII), hyaluronic acid (HA), laminin (LN), malondialdehyde (MDA), nitric oxide (NO), protein carbonyl (PC), tumor necrosis factor-α(TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and hydroxyproline (Hyp) and increase the levels of superoxide dismutase (SOD), glutathione (GSH), and catalase (CAT). Hematoxylin-eosin (H&E), Sirius red, and Masson staining showed AEPE-treated improved fibrotic lesions and inflammatory cell infiltration. Meanwhile, AEPE treatment also significantly downregulates the expression of α-smooth muscle actin (α-SMA) and transforming growth factor-β1 (TGF-β1) in the liver tissue and serum, respectively. In conclusion, AEPE possesses curative efficacy against liver fibrosis through its antioxidant, anti-inflammatory, and antifibrotic effects.
INCEPTION OF HARMONISING DATA SILOS AND URBAN SIMULATION TOOLS USING 3D CITY MODELS FOR SUSTAINABLE MANAGEMENT OF THE URBAN FOOD WATER AND ENERGY RESOURCES

Abstract. This paper explains the first insights into the ongoing development of a CityGML based Food Water Energy Application Domain Extension (FWE ADE). Cities are undergoing rapid expansion throughout the globe. As a result, they face a common challenge to provide food, water and energy (FWE) supplies under healthy and economically productive conditions. Consequently, new tools and techniques must be developed to support decision-makers, such as governments, public or private infrastructure providers, investors and city developers, to understand, quantify and visualise multiple interdependent impacts for the sustainable supply of the FWE resources. However, a common practice amongst these stakeholders is to work in their data silos, which frequently results in a lack of data integration and communication between domain specific simulation tools belonging to different infrastructure departments. As a result, insights related to critical indicators showing inter-dependency amongst different urban infrastructure are missed and hence, not included in the cities’ redevelopment action plan. This paper documents the first ongoing attempt by an international group of domain experts from food, water, energy, urban design and geoinformatics to harmonise the data silos of food, water and energy domain for the case study regions of the County of Ludwigsburg in Germany, the city of Vienna in Austria and the neighbourhood of Gowanus in New York, the United States of America.
Impacts of genetic selection on Sequoia sempervirens mini-cutting rooting and initial growth in the field

Background: Vegetative propagation from superior individuals allows multiple copies of plants that are genetically identical to the parent plant to be obtained. However, vegetative propagation success varies among individual genotypes, with some clones having more difficulty forming roots than others. The aim of this study was to evaluate the genetic gain in Sequoia sempervirens (D.Don) Endl. clones using parameters describing vegetative propagation success and initial growth in field. Methods: Vegetative propagation success was quantified for 16 clones in a completely randomised design consisting of 10 replications, each containing 10 mini-cuttings. At 90 days, rooting (RT), survival (SV) and the number of new shoots (NS) were evaluated. Performance after planting in the field was assessed using 13 clones from the previous experiment, arranged in linear parcels of 10 plants with 8 replicates. After 18 months, survival (SV), stem diameter (SD), height (H) and dominance breakdown (DB) were assessed. Estimates of variance components, heritability and genetic correlations were obtained using the Selegen-REML/BLUP software. Results: The mini cuttings of the 16 clones had a coefficient of genetic variation (CVgi%) of 32.32% for RT, 5.44% for SV and 5.35% for NS. The heritability of the total genetic effects (H2 g) for RT was 0.68. The clones with the best predicted genotypic classifications for the characteristics evaluated in the field were A116, A140 and A138 for SV, A126, A140 and A138 for SD, A138, A140 and A117 for H and A138, A228 and A116 for DB. Conclusions: In general, it was possible to obtain high genetic gain for rooting and medium gain for dendrometric variables in the field.

Microplastics Contamination in the Environment: An Ecotoxicological Concern

The accumulation of plastic products in the terrestrial and aquatic environment is one of the major concerns in recent years. The quality of the ecosystem is affected globally due to the large production, ubiquitous usage, and poor plastic waste disposal. Plastic debris is categorized based on its size as macroplastics, mesoplastics, microplastics, and nanoplastics, respectively. Microplastics are the emerging contaminant that occurs in varying shapes like tiny beads, spheres, films, fragments, fibres, and filaments. The use of microplastics in cosmetics and abrasion from large plastic items including textile fibres and tyres are suspected to contaminate the environment when it reaches the aquatic ecosystem. Indian coastal waters are polluted by microplastics owing to industrialization, overpopulation, tourist and maritime activities. Many species of fishes, reptiles, birds, and mammals are directly threatened by entanglement or ingestion, and some marine mammals consume a large amount of microplastic debris by raptorial feeding thereby leads to trophic transfer. Humans are considered as the most exposed organisms than other vertebrates as they occupy at the top of the food chain. Certain government legislations have been put forth to ban some products that are considered as the major contributor to plastic debris. Recently, the use of bioplastics is increased all over the world to replace microplastics in industrial and commercial products. However, there is little awareness of the microplastic pollutants among the public, thus the main motive of this review is to provide public awareness and responsibility to limit the use of plastics that adversely damage our environment
