The Production of Biodiesel From Jatropha Curca and Its Social Impact

The social impact of planting and harvesting the jatropha curca for the production of biodiesel in the province of Manabí is shown, where there are several municipalities involved in this process, mainly the populations that live in rural areas where the conditions are created for their improvement of quality and good living from the income they receive for performing these tasks. A social relationship model was designed that links the social development of rural areas in the province of Manabí with the sowing, harvesting and industrialization of jatropha curca in social development, demonstrating the benefit of using indigenous natural resources for the in the improvement of the quality of life of the populations directed to the economic, energetic, social and environmental sustainable development

The Role of Language in Building Characters in Caragiale’s Comedies

The study aims to emphasize some critical opinions that observe and illustrate the power and talent of I.L. Caragiale to imagine a human character or a comic situation with the creative force of words. The characters are outlined in all the comedies from the first act, the dominant features of the heroes being highlighted in particular by language features. The study proposes an analysis of both the critical direction that considers the diversity of the Caragiale social typology to be classical, as well as the modern vision that the grotesque comic in Caragiale's plays relate to life in its entirety, the world of Caţavencu and Conu Leonida being a hopeless world

Engine performance of a single cylinder direct injection diesel engine fuelled with blends of Jatropha Curcas oil and stardard diesel fuel

Blends of Jatropha Curcas oil and standard diesel fuel were evaluated (without pre-heating). The engine tests for the blends were performed in a Petter single cylinder direct injection diesel engine under steady state conditions at high loads. Engine speeds between 1300-1700 rpm were selected for the engine tests. Torque, power output, specific fuel consumption, in cylinder pressure, ignition delay, rate of heat released and exhaust composition were evaluated. The tested blends between 10-20% of oil shown lower effective torque and power output joint to a higher specific fuel consumption related to the lower heating value of Jatropha oil compared to diesel fuel. Lower pressure peaks and rates or pressure rises were observed when Jatropha blends are used. A decrease in the rate of heat released and shorter ignition delay were observed for the blends. Decreases in HC and CO emissions were observed for blends compared to diesel fuel. Both alternatives assessed shown that the differences observed compared to diesel fuel, can be partially restored with engines regulation. The use of Jatropha oil in order to be a partial or full alternative to the use of diesel fuel for energy production was achieved

Use of Interactive Triva for Learning the Laws of The Game

Este artículo presenta un modelo de trivia interactivo diseñado por el grupo de investigación TECMERIN en colaboración con la Fédération Internationale de Football Association (FIFA), como material educativo para facilitar el aprendizaje de las Reglas del Juego a los árbitros y árbitros asistentes. Se explica la estructura y dinámica del juego, la tecnología usada en su desarrollo y sus fundamentos teóricos, y se analizan las ventajas e inconvenientes del modelo como recurso para la enseñanza y la evaluación. Los resultados confirman la posibilidad de extrapolar el modelo a otros ámbitos de aprendizaje.This paper presents the interactive Quiz Game designed by TECMERIN research group in collaboration with the Fédération Internationale de Football Association (FIFA) as an educational resource to facilitate learning of referees and assistant referees in football.

Bacterial diversity and community structure of salt pans from Goa, India

In Goa, salt production from the local salt pans is an age-old practice. These salt pans harbor a rich diversity of halophilic microbes with immense biotechnological applications, as they tolerate extremely harsh conditions. Detecting the existence of these microbes by a metabarcoding approach could be a primary step to harness their potential. Three salt pans viz. Agarwado, Curca, and Nerul adjoining prominent estuaries of Goa were selected based on their unique geographical locations. The sediments of these salt pans were examined for their bacterial community and function by 16S rRNA amplicon-sequencing. These salt pans were hypersaline (400–450 PSU) and alkaline (pH 7.6–8.25), with 0.036–0.081 mg/L nitrite, 0.0031–0.016 mg/L nitrate, 6.66–15.81 mg/L sulfate, and 20.8–25.6 mg/L sulfide. The relative abundance revealed that the Pseudomonadota was dominant in salt pans of Nerul (13.9%), Curca (19.6%), and Agarwado (32.4%). The predominant genera in Nerul, Curca, and Agarwado salt pan sediments were Rhodopirellula (1.12%), Sulfurivermis (1.28%), and Psychrobacter (25.5%) respectively. The highest alpha diversity (Shannon-diversity Index) was observed in the Nerul salt pan (4.8) followed by Curca (4.3) and Agarwado (2.03). Beta diversity indicated the highest dissimilarity between Agarwado and the other two salt pans (0.73) viz. Nerul and Curca and the lowest dissimilarity was observed between Nerul and Curca salt pans (0.48). Additionally, in the Agarwado salt pan, 125 unique genera were detected, while in Nerul 119, and in Curca 28 distinct genera were noted. The presence of these exclusive microorganisms in a specific salt pan and its absence in the others indicate that the adjacent estuaries play a critical role in determining salt pan bacterial diversity. Further, the functional prediction of bacterial communities indicated the predominance of stress adaptation genes involved in osmotic balance, membrane modification, and DNA repair mechanisms. This is the first study to report the bacterial community structure and its functional genes in these three salt pans using Next-Generation Sequencing. The data generated could be used as a reference by other researchers across the world for bioprospecting these organisms for novel compounds having biotechnological and biomedical potential
