The induction motor (IM) is most frequently used for industrial purposes because of its low price, high performance, low maintenance and good robustness. Despite of these advantages, the IM has three drawbacks: (i) it is a complex (ii) it is a nonlinear and (iii) it can not operate at variable speed. These drawbacks can be overcome by fuzzy logic controller (FLC). The FLC has many benefits such as: it can form non-linear functions of complexity, values of model need not be known exactly on designing controller and not require model of the plant. In this paper, conventional proportional integral (PI) controller and fuzzy proportional integral (Fuzzy PI) controller for speed control of IM are analyzed. The Fuzzy-PI controller is implemented using feedforward vector control (FFVC) technique in Matlab/Simulink. The feed forward vector control is more it enables better speed control of IM with higher dynamic performance. It is observed from the simulation results that Fuzzy-PI controller performance is best in terms of small peak time, fast settling time frequently used because and no percentage overshoot.

Background: There is increasing consumption of herbal products worldwide. However, data about community pharmacists’ (CPs) knowledge, attitude and practice of herbal products in Northern Cyprus is scare.\n\nObjective: This study aimed to investigate the current knowledge, attitudes and practice regarding herbal products as well as evaluating the effectiveness of the educational intervention.\n \nMethod: In the first phase of study, a cross-sectional study was conducted among CPs located in Northern Cyprus. A total of 203 CPs were enrolled and assessed by using self-administered questionnaire on herbal products. In the second phase, an educational program about herbal products was provided to pharmacists who participated in first phase. Data were analysed using SPSS, version 22.0.  The Pearson correlation and Paired t-test was used to measure the intervention effect. (P < 0.05).\n\nResults: A total of 203 and 138 CPs were enrolled in the first and the second phase of the study. Majority of the pharmacists are females (160 of 203, 78.8%). Herbal products were “often” or “always” dispensed by 71.9% of CPs. Pharmacists’ have a greater knowledge regarding purported indications of selected herbal products then about other aspects such as drug interactions, adverse events and contraindications. Pharmacists’ age and degree of education were significantly associated with good knowledge and educational intervention can significantly improve the knowledge score of pharmacists (P < 0.05).\n\nConclusion: Community pharmacists were having a positive attitude towards herbal products and they were more familiar with the indications of herbal products rather than their side effects and interactions.

Human schistosomiasis is a worldwide parasitic disease which is considered a problem in global health. The present study was carried out to evaluate the efficacy of miltefosine as synthetic drug and artemether as natural derived drug against Schistosoma mansoni and their molluscidal activity. The sublethal concentration of miltefosine (8.2ppm) and artemether (11.04) induced a marked significant increase in mortality rate, significant decrease in egg laying capacity and infection rate with miracidia of treated B. alexandrina snails. Also, they exhibited significant reduction in immature and mature ova in liver tissue of treated mice comparable with control group. The both drugs induced biochemical effects such as significant decrease in total protein and albumin content, significant elevation in total lipid content and activity of transaminases (AST, ALT) of treated infected snails. A significant increase in total liver protein content, significant decrease of glucose content and increase of glycogen level when compared with infected mice. The treatment with tested drugs induced significant increase (P < 0.05) in AST and ALT level in the liver of treated infected mice comparable with untreated infected mice. The treatment leads to normalize and recover the glycolytic enzyme activities after infection with S. mansoni. It can be concluded that both miltefosine and artemether are a promise molluscicdal as well as antischistomicidal agents against S. mansoni.
