 Abstract

Due to the high cost of petroleum products and the environmental effects of synthetic plastics, it has to be replaced by biopolymers because they are potentially strong and have a degrading capacity in nature. The alternative for plastic could be polyhydroxyalkanoates (PHAs), polyhydroxybutrate (PHBs) and polylactic acid (PLAs). They are abundant in starch and sugar industrial agro waste which helps to produce biopolymers at low cost which are then successfully converted into PHAs, PHBs, and PLAs. This conversion is mediated by the microbial isolates or genetically modified microbes by converting microbial biomass into biopolymers and optimizing the conditions for the fermentation of sugar obtained from the agro-industries. Easily available starch and sugar industrial agro wastes contain nutritional value. So, it is being used as the substrate for microbial growth. Nowadays the research aspects were critically increased on microbial biopolymer and its production. In this paper, the different aspects of biopolymer production and the challenges involved in overcoming the problems are being reviewed.

 Abstract

The process of choosing the best composite material for a given application is based on the application's needs and desired characteristics. To guarantee optimum performance and functionality, factors including hardness, weight, toughness, cost, and adaptability with the target environment must be taken into care. Choosing the best "composite material" for a given application requires thorough consideration and evaluation of available options. Mechanical features, ambient circumstances, cost, manufacturing viability, and desired performance attributes are all taken into account during this procedure. Engineers can identify a composite material that satisfies particular specifications and achieves the ideal mix of attributes and performance by examining these aspects. Arguably, the most demanding phases in the planning and creation of any structural part is selecting the right kind of materials. The factors of the composites such as "Interlinear shear strength, tensile strength, flexural strength, impact strength, and Micro-hardness", are taken into consideration all over the process of choosing them. A decision-making methodology called "MOORA" evaluates and prioritizes options considering a number of factors. It creates an overall performance index, turns the criteria into ratios, and establishes the weights for each criterion. "MOORA", which is utilized extensively in business, engineering, and research on the environment, offers a methodical way to choose the optimal option by taking into consideration of relative relevance as well as performance levels. Alternate Parameters are "PSF1, PSF2, PSF3, PSF4, VSF1, VSF2, VSF3, and VSF4". Evaluation Parameters used are Micro-Hardness, Tensile strength, Flexural Strength, Interlaminar shear strength, and Impact strength. For the composite material selection, "VSF3" is in the 1st rank, "PSF3" in the 2nd rank, "VSF4" in the 3rd Rank, "VSF2" in the 4rth rank, "PSF2" in the 5fth rank, "PSF4" in the 6th rank, "VSF1" in the 7th rank, and "PSF1" in the 8th rank. the 3rd Rank, "VSF2" in the 4rth rank, "PSF2" in the 5fth rank, "PSF4" in the 6th rank, "VSF1" in the 7th rank, and "PSF1" in the 8th rank.

 Abstract

The intersection of mental health and educational equity for college students is crucial, as disparities in access to resources and support can impact students' well-being and academic success.College students from marginalised communities are at a higher risk of mental health issues due to various systemic factors, such as discrimination, poverty, and lack of access to resources. These students are often not adequately supported, and their mental health needs are not given priority, despite the impact this could have on their academic performance. Furthermore, the lack of mental health resources available to all students regardless of their background can create a sense of educational inequality. For example, students who do not have access to counselling or other resources may struggle to stay on top of their academic work, leading to an unbalanced educational experience. This could ultimately lead to the loss of opportunities that would enable these students to succeed beyond the classroom. Strategies should be put in place to ensure that all students have access to the resources necessary to maintain their mental health and succeed academically. This includes providing culturally responsive mental health resources available to students from various backgrounds and creating a supportive campus culture to minimise the stigma surrounding mental health.

 Abstract

Smart surveillance has got tremendous traction in recent years. An important component in smart surveillance is physical violence detection. All existing violence detection models have a preprocessing step where required frames are extracted from a video. The existing interval sampling method is simple and the frames it picks sometimes lose the action in the video. In this literature we have introduced a novel key framing method based on encoding and clustering as a pre- processing step for frame extraction. In the violence detection model, we have used ResNet50 as image encode. Our model is trained on Mix dataset. A dataset formed by combining Hockey fights, Movies and Violent flows dataset. Our model is compared with start-of-the-art models on a test dataset. The test dataset is formed by collecting 20 videos from YouTube and annotating manually. Our key framed model performs better than the state-of-the-art models even with 360 frames less for a 1 minute video clip

 Abstract

The imminent depletion of conventional energy sources has motivated the advancement of renewable energy technologies. Third-generation photovoltaic technologies, such as dye-sensitized solar cells (DSSCs), organic solar cells (OSCs), and perovskite solar cells (PSCs), are being developed as alternatives to silicon solar cells. These technologies have not yet reached the maturity required for large-scale commercialization. More research is required in order to improve the efficiency of these solar cells, while keeping their production costs to a minimum. In this study, a comparative assessment of Dye-sensitized solar cells (DSSCs), Organic solar cells (OSCs), and Perovskite solar cells (PSCs), is conducted. The comparative advantages and limitations of each of these photovoltaic technologies are assessed in terms of device efficiency, durability, fabrication, and performance and find the which solar cell is best among these three.
