“…Human toxicity has been established for several hazardous contaminants. In 2007-2020, the combustion of fossil fuels resulted in the release of 4.1 million metric tonnes of CO 2 globally [6]. Countries in the EU (European Union) alone consume nearly 25.7% of energy in residential sectors responsible for huge CO 2 emission [7].…”

The fuel qualities of several biodiesels containing highly saturated, mono, and poly unsaturated fatty acids, as well as their combustion and exhaust emission characteristics, were studied. Six biodiesel samples were divided into two groups based on their fatty acid composition, including group 1 (coconut, castor, and jatropha) and group II (palm, karanja, and waste cooking oil biodiesel). All fuels (in both groups) were tested in a single-cylinder off-road diesel engine. Castor and karanja biodiesel, both rich in mono-unsaturation level, have a high viscosity of about 14.5 and 5.04 mm2/s, respectively. The coconut and palm biodiesels are rich in saturation level with cetane numbers of 62 and 60, respectively. In both groups, highly saturated and poly-unsaturated methyl esters presented better combustion efficiency and less formation of polluted emissions than mono-unsaturation. At full load, coconut and palm biodiesel displayed 38% and 10% advanced start of combustion, respectively, which reduced ignition delay by approximately 10% and 3%, respectively. Mono-unsaturated methyl esters exhibited a higher cylinder pressure and heat release rate, which results in higher NOx gas emissions. The group II biodiesels showed about 10–15% lower exhaust emissions owing to an optimum level of fatty acid composition. Our study concluded that highly saturated and poly-unsaturated fatty acid performed better than mono-unsaturated biodiesels for off-road engine application.

“…For these reason the optimization of the cultivation process of nonedible oilseed biomass is a very relevant issue. 7,8 Analysis Jatropha Curcas (JC) cultivation has widely spread worldwide since the late 1990s, when its promising potential as a bioenergetic was recognized. JC is native to Mexico, Central and South America, Africa and India.…”

“…22 The Mexican government made relevant efforts to spread JC cultivation in different edapho climatic regions, taking advantage that Jatropha is a highly adaptable crop that grows in marginal soils, resists drought, diseases and some pests reasonably well, and require relatively lower agronomic practices. 8 Mexican agriculture research centers enhanced JC native variety to increase JC seeds and oil production according to local soil and climate conditions. 5 This favorable scenario motivated Mexican farmers to switch from bean and maize to JC cultivation 23,24 and some local and foreign private companies promoted JC oil production at pilot plant scale.…”

An increasing demand of energy and fuels for diverse applications, in addition to the depletion and negative effects of fossil resources, has raised the interest to use nonedible biomass or residual biomass as alternative raw material to produce renewable fuels for heavy vehicles. Currently, several projects around the world aim the sustainable production of green fuels and a major challenge to overcome is to guarantee the continuous supply or biomass required as raw materials. To this purpose, non-edible vegetable oils, such as Jatropha curcas (JC) oil, have been suggested as a very favorable feedstock. In this review, we briefly summarized the potential to produce JC seeds and oil in Mexico as well as the outcomes and challenges found when JC oil was used to biodiesel production. We also identify some the actions required to establish a JC supply chain, which is a basic premise to promote the development of green liquid fuels such as sustainable aviation fuel.

“…Several studies have been conducted to explore the challenges that faculty members face in research production (Alzahrani, 2011;Fawzi & Al-Hattami, 2017;Hagan, Armbruster, & Ballard, 2019). Lack of peer encouragement, lack of research funding, lack of research facilities are the most important challenges affecting research production among the sample of this study (Alzahrani, 2011;Ewunie, Morken, Lekang, & Yigezu, 2021). Faculty members report that insufficient time due to teaching load is the most important challenge they face in research productivity (Fawzi & Al-Hattami, 2017)..…”

There is a dearth of empirical research conducted to investigate the challenges of research productivity among faculty members at universities. This study aims to explore perceptions and challenges of research production. This research is quantitative. Data was taken using an instrument in the form of a questionnaire. The population and sample in this study amounted to 55 people. The results of this study indicate that long waiting periods for manuscript publication, lack of time allocation for research, and lack of research training programs are the most prominent challenges in research production. The participants have also submitted several suggestions to increase research products such as conducting research training programs, providing research incentives, and providing adequate research facilities. So, it can be concluded that members are aware of the importance of research publications in their career advancement. They also provide some of the challenges faced when writing research such as insufficient time allocation for research, lack of research training, and lack of research facilities.
