Wafa A. Baker Bawazir
International Journal of Organic Chemistry (IJOC) , 2019, DOI: 10.4236/ijoc.2019.91004
Abstract: Some new asymmetric thioethers 5 and 4-thiazolidinones 6 have been obtained from condensation of 5-formyl-3-(pyridin-4'-yl)-1,2,4-triazino[5,6-b] indole (3) with halogenated aromatic amines followed by addition of thiophenol and/or cycloaddition with thiolactic acids in nonpolar solvents. Structures of the products confirmed by elemental analysis and spectral measurements. The new systems obtained were evaluated as antifungal agents.

International Journal of Organic Chemistry (IJOC) , 2018, DOI: 10.4236/ijoc.2018.82014
Abstract: A simple condensation afforded some new 3-thioxo-1,2,4-triazin-5-one derivatives (4, 6 and 8). Utilizing a facile condensation of (E)-4-(4’-bromo styryl)-2-oxo-3-buteneoic acid with thiosemicarbazide, dithioic formic acid hydrazide, and thiocarbahydrazide in different conditions. Structures of these compounds were confirmed by elemental and spectral analysis. The preliminary biocidal activity of these products were evaluated against some microbial and compared to Mycostatine and piperacillin as antibiotics were most of derivatives exhibited good activity.

Chronic effect of olive oil on some neurotransmitter contents in different brain regions and physiological, histological structure of liver and kidney of male albino rats  [PDF]

World Journal of Neuroscience (WJNS) , 2011, DOI: 10.4236/wjns.2011.13005
Abstract: Olive oil is an important source of mono-unsaturated fat and a prime component of the Mediterranean diet. The beneficial health effects of olive oil are due to both its high content of mono-unsaturated fatty acids and its high content of anti-oxidative substances. The objective of this study was to investigate the basis for the epidemiological information relating to the health benefits associated with the consumption of ex-tra-virgin olive oil (EVOO). The effect of olive oil on norepinephrine (NE), dopamine (DA), serotonin (5-HT) and gamm-aminobutyric acid (GABA) con-tents in different brain regions and histological structure of liver and kindey of male albino rats was studied. The chronic administration of olive oil (7.5 mg/kg body wt.) caused a significant increase in norepinephrine (NE), dopamine (DA) , serotonin (5-HT) and gamm-aminobutyric acid (GABA) con-tent in different brain regions (Cerebellum, striatum, cerebral cortex, hypothalamus, brain steam and hip-pocampus) of male albino rats. The increase in NE, DA, 5-HT, and GABA content in the different CNS areas of male albino rat may be due to the inhibition of Ca2+/calmodulin binding which plays an important role in the release of these neurotransmitters. The results, also, revealed that urea and creatinne con-centrations in rats with oral administration with olive oil were decreased. Meanwhile, the activities of the enzymes AsT, AlT and ALP were elevated. The pre-sent results indicated that there is no change in tis-sues of kidney after treated with virgin olive oil. Olive oil may potentially be safe for use as a sedative drug. improvement also led to the reductions in risk of Alzheimer’s and Parkinson’s diseases.
Reliability Evaluation of Distribution Systems under μ Grid-Tied and Islanded μ Grid Modes Using Monte Carlo Simulation  [PDF]
Ahmed R. Abul’Wafa, A. T. M. Taha
Smart Grid and Renewable Energy (SGRE) , 2014, DOI: 10.4236/sgre.2014.53006
Abstract:

Reliability evaluation of distribution networks under grid-tied and islanded μ grid modes is presented. The Monte Carlo simulation (MCS) algorithm is applied to a modified RBTS Bus 2 distribution network. The network includes three types of distributed energy resources, namely, solar photovoltaic (PV), wind turbine (WT), and diesel turbine generator (DTG). These distributed generators contribute to supply part of the load during grid-connected mode, but supply 100% of the load in the islanded μ grid mode. A storage system is included to decrease the peak load since the peak of the output power of the PV’s and the peak load do not match time wise in most load profiles. The impact of implementing renewable distributed generation, storage systems, and conventional generation on the reliability of distribution network is studied. This study shows that the penetration of distributed generations can improve the reliability indices of the distribution network.

Open Journal of Modern Linguistics (OJML) , 2014, DOI: 10.4236/ojml.2014.45053
Abstract: A full-day summer conference directed by this investigator took place in Dearborn city under the umbrella of Western Michigan University for professional development of Arabic teachers serving public, private, and academic charter schools in Michigan. The theoretical framework for conducting the conference was focused on the issue of teaching strategies as well as the needs assessment of teachers for improving their professional development. A group of fifty teachers volunteered to participate in the conference and were asked to complete a twelve-item questionnaire designed to provide their professional profile and their preference in developing professional development. Their professional profile included years of Arabic teaching experience in the United States, teaching level (elementary school, middle school, or high school), teaching certificate, academic credentials, and type of school (public, private, or charter school). The findings indicated that among the ten sub-items related to the professional development skills of the teachers, “Implementing differentiated language instruction” was rated by the participating teachers as the most important components of their professional development skills; followed in order by “Integrating technology and Arabic instruction”; “Using effective learner-centered teaching strategies”; “Using and maintaining Arabic language”; “Implementing a standards-based curriculum”; “Developing curriculum and thematic units”; “Implementing performance assessment methods”; “Conducting constructive action research in Arabic instruction”; “Conducting the Oral Proficiency Interview”; and “Learning how to be a certified Arabic language teacher in Michigan”. In response to the questions regarding the role of Council in supporting Arabic teachers, the participating teachers made a number of constructive suggestions to help improve the quality of teaching Arabic with special focus on facilitating appropriate teaching materials and other instructional tools as a part of curriculum development.

Abstract: Due to the ever growing number of cyber attacks, especially of the online systems, development and operation of adaptive Intrusion Detection Systems (IDSs) is badly needed so as to protect these systems. It remains as a goal of paramount importance to achieve and a serious challenge to address. Different selection methods have been developed and implemented in Genetic Algorithms (GAs) to enhance the rate of detection of the IDSs. In this respect, the present study employed the eXtended Classifier System (XCS) for detection of intrusions by matching the incoming environmental message (packet) with a classifiers pool to determine whether the incoming message is a normal request or an intrusion. Fuzzy Clustering by Local Approximation Membership (FLAME) represents the new selection method used in GAs. In this study, Genetic Algorithm with FLAME selection (FGA) was used as a production engine for the XCS. For comparison purposes, different selection methods were compared with FLAME selection and all experiments and evaluations were performed by using the KDD’99 dataset.
