Abstract: Using fishnet as reinforcement in cement mortar sheets is one possibility. In a preliminary analysis, the mechanical characteristics of mortar with nylon fishnet reinforcement are assessed. Waste nylon fishnet is employed in this study as mortar reinforcement. The compressive strength of mortar has decreased as a result of the addition of nylon fishnet. Also, the adding together of nylon based fishnet enhances several mortar qualities, such as its capacity to support a load. The sheet reinforced with fishnet is cheap and eco-friendly. Even though more research is required, it.....

Abstract: At present, it's understandable how global warming, the greenhouse effect, and the increasing population are causing negative effects on the environment. India has the largest population in the world with more than 1.43 billion people (2023 census of India) contributing to adverse the environment in many direct and indirect ways. The construction/Infra sector lacks Green Building methods. Major challenges of green building implementation are lack of awareness, unavailability of required construction materials, skilled labour, and expensive low-carbon construction....

Abstract: During the dry season, several areas in Indonesia such as East Java, NTB and NTT experience a clean water crisis. One way to overcome the problem of the clean water crisis is to make a machine that harvests water from the air (air-water harvester). This study uses 3 evaporators to increase the freshwater production. The positions of the fans are at the entrance and at the exit. The diameter of the copper pipe used to make the evaporator is 6.35 mm, the coil diameter is 80 mm and the number of coils is 26 per evaporator, and the inlet air speed used in this study is 5 m/s which is the same for all fan locations. The research results show that the highest water mass and the total heat transfer rate are 1.003 kg for 7 hours and 267 W obtained for the fan position at the inlet (air is pushed into the machine).

Keywords: Air-water harvester; frehwater production; fan location; total heat transfer.

Abstract: India is endowed with vast solar resources, with about 5,000 trillion kWh per year of energy incident over India's land area, with most parts receiving 4-7 kWh per sqm per day. The National Institute of Solar Energy (NISE) has assessed the country's solar potential to be about 748 GW. The government is bullish on realizing this solar potential, setting out ambitious targets to install 500 GW of non-fossil fuel capacity by 2030, with Solar projects contributing a major chunk of it. Reports suggest that investments up to $294bn would be required to meet India's solar and wind targets. However, this capital expenditure can be reduced or controlled by deploying our solar projects prudentially. This paper intends to quantify the effect of variations in Solar PV module efficiency due to varying technology and changes in solar irradiation according......
