ENHANCEMENT OF STATIC & DYNAMIC RESPONSE OF THE THREE PHASE INDUCTION MOTOR UNDER THE EFFECT OF THE EXTERNAL DISTURBANCES AND NOISE BY USING HYBRID FUZZY-GENETIC CONTROLLER
Journal ArticleABSTRACT:- For electrical drives good dynamic performance is mandatory so as to respond to the changes in command speed and torques, so various speed control techniques are being used for real time applications. The speed of a Three Phase Induction Motor can be controlled using various controllers like PID Controller, Fuzzy Logic Controller, Genetic Algorithm (GA) controller and Hybrid FuzzyGenetic Controller. Fuzzy-Genetic Controller is recently getting increasing emphasis in process control applications. The paper describes application of Hybrid Fuzzy-Genetic Controller in an enhancement of Static & Dynamic Response of the Three Phase Induction Motor under the effect of the external disturbances and noise that uses the Fuzzy-GA Controller for enhancement of Static & Dynamic Response of the Three Phase Induction Motor under the effect of the external disturbances and noise is implemented in MATLAB/SIMULINK. The simulation study indicates the superiority Hybrid Fuzzy-Genetic Controller over the Genetic Algorithm and fuzzy logic controller separately. This control seems to have a lot of promise in the applications of power electronics. The speed of the Three Phases Induction Motor Drives can be adjusted to a great extent so as to provide easy control and high performance. There are several conventional and numeric types of controllers intended for controlling the Three Phase Induction Motor speed and executing various tasks: PID Controller, Fuzzy Logic Controller; or the combination between them: Fuzzy-Swarm, Fuzzy-Neural Networks,
Fuzzy-Genetic Algorithm, Fuzzy-Ants Colony. We describe in this paper the use of Hybrid FuzzyGenetic Controller for enhancement of Static & Dynamic Response of the Three Phases Induction Motor Drives under the effect of the external disturbances. In this case, the obtained results were simulated on Simulink of Matlab.

Cutaneous leishmaniasis infection among children in comparison to adults in Al-jabal Al-gharbi, Libya
Journal ArticleCutaneous leishmaniasis is considered as an endemic parasitic infection in certain areas of Libya. One of these established areas is Gharian province. One hundred and forty cutaneous leishmaniasis cases were recorded in Gharian outpatient polyclinic during the period from December 2007 to May 2008. Of these cutaneous leishmaniasis cases, sixty seven cases were children and seventy three cases were adults. The infection was clinically diagnosed and confirmed by the demonstration of Leishmania parasite on smears from lesion biopsies. These Cutaneous leishmaniasis (CL) cases were classified according to the gender and age. We found that the percentage of infected male children and adult cases (58.20% and 56.16% respectively) was more than that of the infected female children and adult cases (41.79% and 43.84% respectively).We observed that the highest number of the infected children cases was within 10 - 14 years age group of both sexes, while the highest number of affected adults was within 25 - 35 years age group of both sexes. The study of geographical distribution of both children and adult CL cases within Aljabal Algharbi subprovinces revealed that the majority of both children and adult CL cases have been reported from Al-kawasem subprovince, while there was difference in the geographical distribution of minority of both adult and children CL cases. The majority of the reported children CL were school children while the minority was preschool children. In adults, the majority of adult CL cases were officers, students and housewives,while the minority of adult Cl cases were nurses. In children, the percentage of the CL cases that had single and multiple lesions was approximately equal. On the other hand, the percentage of the adult CL cases that had multiple lesions was more than the percentage of the adult CL cases that had single lesions. We observed that the pattern of distribution of CL lesions was different between children and adult cases. In children, it was found that the face was the most affected part in male and female cases; the upper and lower extremities were the moderately affected parts in both sexes, while the least affected part in male and female cases was the back. In contrast, in adults, it was found that the most affected parts in male and female cases were the upper and lower extremities, while the face and neck were the least affected parts in male and female cases. There was three clinical presentations of the disease in this study; nodular, ulcerated nodular and crusted nodular. In children and adults, the majority of the CL cases had ulcerated nodular lesions, while the minority of the CL cases had crusted nodular lesions. All reported cutaneous leishmaniasis have been treated. The majority of the CL cases have been treated with only local liquid nitrogen cryotherapy, while the minority was treated with antimony compounds. The cutaneous leishmaniasis cases in this study showed various clinical patterns, different types of lesions and various geographical distributions. This suggests that there may be more than 2 on species of Leishmania responsible for the cutaneous leishmaniasis infection among people of Al-jabal Al-gharbi province. This needs further study to identify the species of Leishmania responsible for the disease.

New insights into mechanisms of opioid inhibitory effects on capsaicin-induced TRPV1 activity during painful diabetic neuropathy
Journal ArticleAbstract
Painful diabetic neuropathy is a disease of the peripheral sensory neuron with impaired opioid responsiveness. Since μ-opioid receptor (MOR) activation can inhibit the transient receptor potential vanilloid 1 (TRPV1) activity in peripherally sensory neurons, this study investigated the mechanisms of impaired opioid inhibitory effects on capsaicin-induced TRPV1 activity in painful diabetic neuropathy. Intravenous injection of streptozotocin (STZ, 45 mg/kg) in Wistar rats led to a degeneration of insulin producing pancreatic β-cells, elevated blood glucose, and mechanical hypersensitivity (allodynia). In these animals, local morphine's inhibitory effects on capsaicin-induced nocifensive behavior as well as on capsaicin-induced TRPV1 current in dorsal root ganglion cells were significantly impaired. These changes were associated with a loss in MOR but not TRPV1 in peripheral sensory neurons. Intrathecal delivery of nerve growth factor in diabetic animals normalized sensory neuron MOR and subsequently rescued morphine's inhibitory effects on capsaicin-induced TRPV1 activity in vivo and in vitro. These findings identify a loss in functional MOR on sensory neurons as a contributing factor for the impaired opioid inhibitory effects on capsaicin-induced TRPV1 activity during advanced STZ-induced diabetes. Moreover, they support growing evidence of a distinct regulation of opioid responsiveness during various painful states of disease (e.g. arthritis, cancer, neuropathy) and may give novel therapeutic incentives.

Applications of web produced by hot air assisted melt differential electrospinning method
Conference paperMelt electrospinning, a technique that has gained increasing attention since it easily can generate continuous ultrafine fibers directly from polymer melts without the use of any solvent. Therefore, it is considered as a safe, cost effective, and environmental friendly technique. However, with all those great advantages, the technique still suffers some drawbacks such as: large fiber diameter and low throughput. The hot air assisted melt differential electrospinning (MDES) is a new technique invented by our research team that can solve or eliminate those drawbacks. The most important features of our used apparatus are: Needleless nozzle that could generate multiple Taylor cones around the bottom edge of the nozzle, which can result in a high throughput. The stretching force acting on the jets can be further strengthened by an air current provided by an air pressure gun. Interference between the high voltage supply …
