This study examines the performance, combustion, and emissions characteristics of a single-cylinder internal combustion diesel engine when fueled with blend biodiesel derived from muskmelon seeds. The kinematic viscosity extracted seed oil was 6.1 cSt at 40 °C, which is higher than petroleum 2.6 cSt. Muskmelon further analyzed using thin-layer chromatography (TLC) high-voltage separator tests. A comparison fuel properties conventional revealed that could be used alone or in diesel–biodiesel to compression engines. In this study, blended proportions 10 %, 20 50 % (BD10, BD20, BD50, respectively). At relatively low rotational speed 1200 rpm, brake thermal efficiency (BTE) operated BD10 BD20 blends were 36.1 36.0 respectively, while brake-specific consumption (BSFC) two 0.260 kg/kWh, 0.262 respectively.

Abstract Barley ( Hordeum vulgare L.) is a significant cereal crop belonging to Poaceae that essential for human food and animal feeding. The production of barley grains was around 142.37 million tons in 2017/2018. However, the growth influenced by salinity which enhanced applying foliar spray salicylic acid. current study investigated evaluated potential effect SA on plants under stress its possible effects physiological, biochemical, responses. experiment conducted at Postgraduate Research Station (PARS), University Agriculture; Faisalabad assess influence acid highly saline conditions.

Overuse of non-renewable fossil fuels due to the population explosion urges us focus on renewable such as bioethanol. It is a well-known fact that ethanol useful blending product with common petrol and diesel. This reduces cost besides bringing down environmental pollution. Apart from chemical methods, bioethanol generated photosynthetic plants including algae, plant-based products, microbial organisms their waste. Specifically, production microalgal sources has been an attractive method in recent days. The reason behind using species simple structure ability. In contrast, certain algal often go disused some regions. Hence, one best waste management practices. Moreover, it easy improve biomass by altering physicochemical conditions light, pH, temperature, external supply nutrients, vitamins, nano-sized particles, gene alterations etc., which will enhance production. this review, methods used for are discussed. addition, factors involved growth emphasized.
