Evaluation Of Salt-Tolerant Traditional Rice Varieties in Mekong Delta, Vietnam
No full textThis study was carried out from 9/2022 to 2/2023, at Can Tho University, Vietnam. This study evaluated seedling stages’ salt tolerance in nutrient solution using three electrical conductivity (EC) salt concentrations of 9.38, 12.50, and 15.63 dS/m with fifteen traditional rice varieties. Five traditional salt-tolerant rice varieties at the seedling stage (level 5) at 15.63 dS/m were selected. Furthermore, we evaluated salt tolerance at EC 9.38, 12.50, and 15.63 dS/m in the vegetative and reproductive stages of seven rice varieties (a tolerant variety, Doc Phung, a sensitive variety, IR28, and five rice salt-tolerant varieties were selected at seedling stage). This study showed that an increase in EC concentrations in the soil significantly reduced plant height, panicle/plant, panicle length, a 1000 grain weight, and yield. The addition of 9.38 dS/m EC can distinguish tolerance and sensitive genotypes. The grain yield of sensitive genotypes decreased by 90%–100% at 9.38 dS/m EC, whereas the tolerant genotypes showed <60% in grain yield reduction. Selected traditional rice varieties of Nang Cha Ran, Nep Than, Trang Lun, Gie Hanh, and Nang Tich were salt tolerant at their seedling stage and vegetative and reproductive stages were at EC 9.38 dS/m
Proximate Analysis of Biomass
Get PDFOne of the sustainable and renewable energy sources that doesn't produce a lot of greenhouse gas emissions is biomass. Using biomass energy effectively will aid in addressing issues brought on by the use of fossil fuels. The biomass has only issue of low calorific value. For biomass as a fuel the calorific value plays a very crucial role. Five diverse biomass species, such as dried Sugarcane Bagasse, Rice Husk, Cotton Waste, Mango leaves and Coal are represented in this context. Agricultural leftovers, coal, and sugarcane bagasse have all been identified through proximate analysis. In this we calculated (moisture, volatile matter, fixed carbon, and ash contents). Next, a number of empirical equations with linear and nonlinear terms are used. This paper also tells about the thermogravimetric analysis method

Health System for Exercise Rehabilitation Detection Retina Images and IoT Blockchain
No full textSmart Healthcare which is based on deep learning is becoming increasingly popular because of its practical applications and has grown popular after its incorporation with IoT. Degenerative eye disease is the main factor of blindness in people of working age. Asian nations with large populations, like India and China, are on the edge of a diabetes epidemic. In terms of medical screening and diagnosis, a large number of diabetes patients posed a huge problem for skilled clinicians. The idea is to employ deep learning algorithms to detect blind spots in the eye and estimate the severity of the stage. We present an optimum approach for detecting blindness in retinal images based on recently released pre-trained EfficientNet models, as well as a comparative assessment of many innovative neural network models, in this study. On a benchmark dataset of retina images obtained by diagnostic imaging at various imaging phases, our EfficientNet-B5-based model assessment performs better than CNN and ResNet50 models
How Does Studying Online Affect the Well-Being of Students with Special Educational Needs and Disabilities?
No full textThe current paper aimed to explore the impact of studying online during the coronavirus pandemic on the well-being of a sample of students (n=74) who were classified as students with Special Educational Needs and Disabilities (SEND) in five Dubai-based schools. An online 18-item Likert scale survey was developed and distributed among participants; however, this resulted in no statistically significant findings. However, there was a slight negative trend, suggesting that the students’ well-being was somewhat affected by studying alone in an online context. Ultimately, the study recommended the need to provide counselling programs to improve the well-being of the students with SEND due to the circumstances imposed on them by the pandemic; and highlights the need for more support services for these students when they study online
