Edible Coatings and Films in Grapevine By-Product Infusions and Freshly Processed Products | Chapter 7 | Research Perspectives of Microbiology and Biotechnology Vol. 1

This book chapter focuses on the environmental issues linked with the wine industry, mainly the amount of waste it generates. However, studies have shown that the by-products of this waste, including grapes, skins, seeds, and leaves, contain essential biocompounds and nutrients like phenolic compounds, flavonoids, procyanidins, and vitamin C that are beneficial to human health. These by-products have been found to possess antioxidant, anti-inflammatory, cardioprotective, anti-aging, and anti-cancer properties. However, due to their perishable nature, they need preservation methods. This chapter recommends using edible films and coatings, a novel and eco-friendly post-harvest preservation technique. This method helps maintain the quality of lightly processed foods, preserve essential nutrients, protect against microorganisms, and maintain their original appearance. Therefore, this review aims to explore different techniques and types of edible coatings like chitosan, agar-agar, gelatin, alginate, guar gum, soy lecithin, maltodextrin, inulin, and propolis for the preparation of grape by-products in foods and drinks. More research is required to optimize coating formulations for the best quality.

Use of Groundnut Shells (Powder) as an Alternative Sculpture Material for Fine Art in Salaga Senior High School, Ghana | Chapter 5 | Research Aspects in Arts and Social Studies Vol. 6

 The fabrics used for teaching sculpt in Salaga Senior High School (SHS) in Northern Ghana have mainly existed clay, cement and wood. Using only these fabrics comes with different limitations. The harsh weather restraints, monotony in the use of the alike materials over long periods and the failure to purchase other matters as they are expensive and inaccessible to undergraduates due to the inadequate capital in purchasing fabrics for studio work have been the main challenges to the productive teaching and knowledge of sculpture in the Salaga SHS. This necessitated an asking into groundnut structures which are abundant in the Salaga society and could be secondhand as a viable sculpture material but is threw away by burning or dumping accompanying consequent loud noises. Through quasi experimental means of inquiry, the scientists used groundnut structures powder with picked binders to determine their suitability for shaping, casting and chiselling. The groundnut shells powder was adapted by collecting, separating, drying, and milling. They conducted a workshop test for the chemical composition and toxicity of the nut shells. The scientists mixed the groundnut structures powder with picked binders in producing aesthetically pleasing formed, cast and carved everything. The findings revealed that nut shells powder is harmless and suitable for sculpture. Groundnut structures powder reacted positively with cassava vigor, Styrofoam, white adhesive (Top Bond), contact adhesive type-99 glue and artificial resin. The done works were strong and smooth to transport. Sculpture teachers and undergraduates of Salaga SHS and other schools as well as those in after second institutions in Ghana are heartened to use groundnut shells (powder) as an alternate sculpt material.

The Finite Element Analysis of Axisymmetric Flow of Air through the Top Riser of Casting Utilizing Stream Function Model | Chapter 12 | Current Approaches in Science and Technology Research Vol. 14

Using the stream function model, this research examines air flow through the upper risers of casting. Casting is a technique for creating intricate structures out of metal. The filling process, which requires the use of a gating system, and the solidification phase, which requires the use of a riser, are the two steps of casting. During casting, molten metal rapidly displaces air in the mould cavity, necessitating a complete understanding of air flow behaviour as it exits the riser. The finite element approach and the stream function model were used to investigate the axisymmetric flow of air through the top risers of casting. According to the findings, the velocity profile at any cross section is parabolic in shape, with the maximum velocity in the centre. When compared to the exact solution, the finite element result converged towards the exact answer.

Study on Indices Assessment of Ergonomic-PsychoSociological Workplace in the Metal Casting Industry of El Hadjar, Algeria | Chapter 5 | Current Approaches in Science and Technology Research Vol. 15

Improving working conditions is a big task for any organisation looking to boost productivity. Workplace conditions are made up of a variety of factors such as material, physical, moral, and so on. These can provide dangers or burdens to workers' health and well-being, which will almost certainly reflect the company's profitability. Our research will look into the working conditions in the casting industry. in a steel facility in A nnaba's El Hadjar Complex (Algeria). The ergonomic-psychosociological quality of work in this workstation is evaluated using the Labor Economics and Sociology Laboratory of France (LEST) approach, with the goal of promoting them in the context of the company's socio-economic development.
