A Theoretical Approach of the Heat Transfer in Nanofluids

The study presents the research results on the identification of technical and safety requirements specific to work equipment made of electrical insulation materials combined with conductive elements, to guarantee safety in use. The identification of the technical and safety requirements specific to the work equipment that is provided with electrically insulating materials combined with conductive elements was carried out, taking into account the safety conditions that must be guaranteed from the design and manufacturing phase. The national technical norms for live work stipulate that the work equipment used for electrical installations must be certified from the point of view of safety and health at work. Research study shows the behavior of various electrical insulation materials combined with conductive elements under the influence of mechanical, electrical, thermal and environmental factors to verify and certify the safety function that must be guaranteed in use. The research results consist of the development of the experimentation and evaluation methodology concerning the legal regulations in force and the evaluation of compliance with the technical and safety requirements identified for work equipment that is provided with electrical insulation materials combined with conductive elements - occupational health of workers and a safe work environment.

et al. 2022

The present work aims to analyze the various aspects relating to olive-vegetative waters (OVW) with particular reference to environmental problems. As is known, olive-vegetation waters are one of the most polluting by-products of the oil industry. They are produced in large quantities and have a polluting potential. For this reason, an in-depth and detailed analysis of the production chain is reported up to the correct and lawful disposal of the olive-vegetation waters. The chemical characteristics of vegetation waters are described, with particular reference to polyphenols, which are the most important compounds present in vegetation waters. The treatments, enhancement, perspectives and possible uses in agriculture are reported.

“…Plastic is one of the most widely used materials, but at the same time it can have a negative impact on human health as well as on the world environment. Plastic is one of the most polluting wastes, and there is a global drive to reduce its impact through several directives [9][10][11]. At European level, according to statistics, around 26 million tons of plastic are generated every year, 80% of which is dumped in water (rivers, lakes, seas, and oceans).…”

Recycling plastic wastes in order to obtain new building materials

This paper presents the development of new types of construction materials using plastic waste. According to the European Court, plastic waste from various sectors such as the automotive, electronics, agriculture and construction sectors is a growing problem and is damaging to both terrestrial and marine media. Thus, every year, between 4.8 and 12.7 million tons of plastics reach the oceans. According to most of the research studies, plastic wastes have the potential to replace the natural aggregate at specific percentages. This paper proposes the reuse of this waste as reinforcement in masonry mortars, using plastic waste in various proportions. The experimental program follows the characteristics of masonry mortars both in terms of the behaviour of fresh mortar and in terms of mechanical strength. The results obtained showed a better performance of mortars reinforced with plastic strips, both in terms of flexural strength and compressive strength.
