For the optimization of refined castor biodiesel (RCB) and refined sesame biodiesel (RSB), the impacts of specified conditions such as catalysts (NaOH and KOH), catalyst concentration (0.3–1.5), speed (500–750 rpm), and time (20–60 min) were investigated. The physicochemical properties of the RCB and RSB were measured using the American Standard for Testing Materials (ASTM) approved protocols for acid, peroxide, iodine, and saponification; density, kinematic viscosity, and refractive index values. Box–Behnken Design's Response Surface Methodology (RSM) was used for optimization. The results for four optimization methods were catalyst concentration (0.300–0.435 percent), speed (500.000–643.242 rpm), and time (20.000–31.386 min). The yield ranged from 81.062 to 102.648 percent, with a desirability range of 0.812 to 0.980 %. These yields were higher when compared to ASTM D 6751 which required a range of 46–55 % in regular biodiesel production. The RSB achieved a maximum yield of 102.649 % while using KOH, compared to 92.017 % in the RCB when using NaOH. The optimum yield of RCB using the KOH catalyst (89.461%) was higher to that of RSB using the NaOH catalyst (81.062%). The catalyst dosage and its nature, were the most essential factor during biodiesel optimization

In this paper, we study the existence of solution to integro-differential equations in the space of Lebesgue-integrable on un-bounded interval after transformed to nonlinear integral functional equation, the used tool is the fixed point theorem due to Schauder with weak measure of non compactness, due to De-Blasi. In addition, we give an example which satisfies the conditions of our existence theorem.

An 3-additive mapping M:RxRxR R is called a symmetric left -3-centralizer if M(u1y,u2 ,u3)=M(u1,u2,u3)(y) holds for all y, u1, u2, u3 R .

The current study included the collection and classification of mosquitoes and the identification of some species because of their medical and veterinary importance in terms of their harmful effect on health and their transmission of diseases. Three species of mosquitoes were diagnosed in the different study sites, namely Anopheles, Culex and Aedes, where five types of Anopheles and four types of Culex were recorded. As for the third genus, two types of it were recorded, and the proportions of the types collected from the study sites varied among themselves, as the percentages varied according to the day and night and the different seasons of the year, and the temperature had a role in this disparity of adults mosquitoes .
