Ce projet pr sente une tude exp rimentale sur les performances d'un caloduc utilisant un nanofluide Al₂O₃ comme fluide de travail pour am liorer les caract ristiques de transfert de chaleur. L' tude compare le comportement thermique du caloduc avec un fluide de travail conventionnel et un nanofluide Al₂O₃ dans des conditions d'apport de chaleur variables. Les principaux param tres de performance tels que le taux de transfert de chaleur, la r sistance thermique, la distribution de la temp rature et l'efficacit globale sont valu s. Les r sultats indiquent que l'utilisation du nanofluide Al₂O₃ am liore de mani re significative la conductivit thermique et r duit la r sistance thermique, ce qui conduit une meilleure dissipation de la chaleur. Les r sultats d montrent le potentiel des caloducs base de nanofluides pour une gestion thermique efficace dans le refroidissement lectronique, les nergies renouvelables et les applications industrielles.

The book focuses on value addition of agricultural produce to create nutrient-rich, sustainable, and marketable food products while reducing post-harvest losses and food waste. Three value-added products were developed: orange biscotti (using orange peel candy to utilize fruit waste), capsicum jam and jam cookies (preserving fresh produce and reducing sugar content), and pumpkin bread (enhancing vitamin content and nutritional quality). These products showed strong market potential, appealing to health-conscious consumers and supporting farmers by increasing profitability. The study highlights the need for further research to optimize production processes, explore new applications, and expand market reach.

Une exp rience doit tre men e sur un moteur diesel monocylindre quatre temps, refroidi par air et injection directe, en utilisant du carburant diesel, de l'ester m thylique d'huile de coton (CSOME), des m langes de diesel et de CSOME dans des proportions de 20 %/80 %, 40 %/60 %, 60 %/40 %, 80 %/20 %, 50 %/50 % en volume. Le biodiesel de graines de coton pr sente une bonne stabilit l'oxydation, mais des propri t s m diocres basse temp rature. Les performances, la combustion et les caract ristiques d' mission du CSOME, des m langes de diesel et de CSOME doivent tre compar es aux r sultats obtenus avec le carburant diesel de r f rence.

Ser realizada uma experi ncia num motor diesel de inje o direta, monocil ndrico, a quatro tempos, arrefecido a ar, utilizando combust vel diesel, ster met lico de leo de semente de algod o (csome), misturas de diesel e CSOME em propor es de 20%/80%, 40%/60%, 60%/40%, 80%/20%, 50%/50% em volume. O biodiesel de semente de algod o tem boa estabilidade oxida o, mas fracas propriedades a baixas temperaturas. As carater sticas de desempenho, combust o e emiss o de CSOME, misturas de gas leo e CSOME devem ser comparadas com o resultado obtido com o gas leo de base

stato condotto un esperimento in un motore diesel monocilindrico, a quattro tempi, raffreddato ad aria e a iniezione diretta, utilizzando gasolio, estere metilico di olio di semi di cotone (CSOME), miscele di gasolio e CSOME nelle proporzioni 20%/80%, 40%/60%, 60%/40%, 80%/20%, 50%/50% in volume. Il biodiesel di semi di cotone ha una buona stabilit all'ossidazione, ma scarse propriet a bassa temperatura. Le prestazioni, la combustione e le caratteristiche di emissione del CSOME, delle miscele di diesel e CSOME devono essere confrontate con i risultati ottenuti con il carburante diesel di riferimento.

In einem luftgek hlten Einzylinder-Viertakt-Dieselmotor mit Direkteinspritzung soll ein Versuch mit Dieselkraftstoff, Baumwollsamen l-Methylester (CSOME) und Mischungen aus Diesel und CSOME in den Volumenanteilen 20%/80%, 40%/60%, 60%/40%, 80%/20%, 50%/50% durchgef hrt werden. Biodiesel aus Baumwollsamen hat eine gute Oxidationsstabilit t, aber schlechte Eigenschaften bei niedrigen Temperaturen. Die Leistungs-, Verbrennungs- und Emissionseigenschaften von CSOME und Mischungen aus Diesel und CSOME sollen mit den Ergebnissen verglichen werden, die mit dem Basisdieselkraftstoff erzielt wurden.

An experiment is to be carried out in a single cylinder, four stroke, air cooled, direct injection diesel engine by using diesel fuel, cotton seed oil methyl ester (csome), blends of diesel and CSOME in proportions of 20%/80%, 40%/60%, 60%/40%, 80%/20%, 50%/50% by volume. Cotton seed biodiesel has good oxidation stability, but poor low temperature properties. The performance, combustion and emission characteristics of CSOME, blends of diesel and CSOME are to be compared with the result obtained from the baseline diesel fuel.

The work proposed is a stoichiometric equilibrium model to predict the yield of syngas and its composition in the gasification of Prosopis Juliflora in a downdraft gasifier. The deep taproots of this plant cause depletion of the water table, and hence, their removal became a necessity. It is used as firewood for household applications and therefore has great potential to be used as biomass. This work aimed to fill the gap in the literature that does not have experimental or modeled values of syngas yield and composition produced by the gasification of this biomass.
