Abstract: The integration of the Photovoltaic (PV) systems changes the nature of the power flow in the network and causes several problems such as voltage deviation which is considered the most important issue in electrical power systems. In this work, the Augmented Grey Wolf Optimization (AGWO) algorithm and advanced nonparametric models are proposed to mitigate the voltage deviation in the distribution network equipped with a PV farm. In the first stage of the work, the AGWO calculates the optimal value of reactive power for Static Synchronous Compensator (STATCOM) to relieve the voltage deviation. This stage is applied only in the offline mode due to the delay in AGWO's dynamic response caused by its iteration process in the computation. Therefore, in the second stage, the data set of AGWO is used to train the nonparametric models; Linear Regression (LR) and Support Vector Machine (SVM) to mitigate the voltage deviation quickly in the online mode. Jordanian Sabha Distribution Network (JSDN) equipped by PV farm is considered and modeled as a real case study to validate the proposed approach. The results showed the superior ability of the proposed integrated approach to handle the voltage deviation quickly and accurately.

Abstract: The voltage deviation is one of the most crucial power quality issues that occur in electrical power systems. Renewable energy plays a vital role in electrical distribution networks due to the high economic returns. However, the presence of photovoltaic systems changes the nature of the energy flow in the grid and causes many problems such as voltage deviation. In this work, several predictive models are examined for voltage regulation in the Jordanian Sabha Distribution Network equipped with photovoltaic farms. The Augmented Grey Wolf Optimizer is used to train the different predictive models. To evaluate the performance of models, a value of one for Regression Factor and a low value for Root Mean Square Error, Mean Square Error, and Mean Absolute Error are used as standards. In addition, a comparison between nineteen predictive models has been made. The results have proved the capability of Linear Regression and the Gaussian Process to restore the bus voltages in the distribution network accurately and quickly and to solve the shortening in the voltage dynamic response caused by the iterative nature of the heuristic algorithm.

Abstract: Hydrogen has universally been considered a reliable source of future clean energy. Its energy conversion, processing, transportation, and storage are techno-economically promising for sustainable energy. This study attempts to maximize the production of H2 energy using nanocatalysts from waste aluminum chips, an abundant metal that is considered a potential storage tank of H2 energy with high energy density. The present study indicates that the use of waste aluminum chips in the production of H2 gas will be free of cost since the reaction by-product, Al2O3 , is denser and can be sold at a higher price than the raw materials, which makes the production cost more efficient and feasible. The current framework investigates seven different copper oxide-based graphene nanocomposites that are synthesized by utilizing green methods and that are well-characterized in terms of their structural, morphological, and surface properties. Reduced graphene oxide (rGO) and multi-layer graphene (MLG) are used as graphene substrates for CuO and Cu2O NPs, respectively. These graphene materials exhibited extraordinary catalytic activity, while their copper oxide composites exhibited a complete reaction with feasible techno-economic production. The results revealed that the H2 production yield and rates increased twofold with the use of these nanocatalysts. The present study recommends the optimum reactor design considerations and reaction parameters that minimize water vaporization in the reaction and suggests practical solutions to quantify and separate it. Furthermore, the present study affords an economic feasibility approach to producing H2 gas that is competitive and efficient. The cost of producing 1 kg of H2 gas from waste aluminum chips is USD 6.70, which is both economically feasible and technically applicable. The unit cost of H2 gas can be steeply reduced by building large-scale plants offering mass production. Finally, the predicted approach is applicable in large, medium, and small cities that can collect industrial waste aluminum in bulk to generate large-scale energy units.

Abstract: The small intestine is where most conventional oral formulations are mostly absorbed. This restricts their usage in the treatment of several colon disorders since the medicine must act topically at the site of inflammation. This opened the door for the development of an intelligent colonic drug delivery system, which enhanced therapeutic effectiveness, decreased dosing frequency and potential side effects, and increased patient acceptance—particularly in situations where enemas or other topical preparations might not be sufficient to treat inflammation alone. This study's primary goal was to develop a smart medication delivery system based on pH-sensitive polymeric formulations made using a free-radical bulk polymerization technique. In the formulations, 5-amino salicylic acid was used as a model drug and Capmul MCM C8 was added to increase bioavailability. The in vitro swelling and release evaluation showed that the developed system may be able to delay drug release under conditions that mimic the stomach and small intestine while triggering it under conditions that mimic the colon, indicating its potential usefulness as a smart colonic drug delivery system.

Abstract: This study was conducted to investigate the effect of different processing treatments in terms of soaking and fermentation of wheat bran on serum lipids and lipoproteins in Sprague-Dawley rats, namely total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high–density lipoprotein cholesterol (HDL-C), triglyceride (TG), and (HDL-C/LDL-C) ratio. The experimental diets included casein diet (zero-bran), untreated bran diet, soaked bran diet, fermented bran diet, soaked and fermented bran diet, arabic bread diet and pectin diet.The animals were randomly divided into seven groups of six animals each according to body weights. Each group of rats was fed one of the seven prepared diets for 6 weeks. Untreated wheat bran has hypercholesterolemic effect since, it significantly (p<0.05) increased TC, LDL-C and decreased HDL-C values as compared with treated bran diets . The soaking ,fermentaion , and “soaking and fermentation ” processes lowered significantly (p<0.05) the TC levels in comparison with casein diet. In addition, soaking ,fermentaion ,and “soaking and fermentation ” processes lowered LDL-C levels in rat groups fed on those treated bran diets in comparison with casein diet. HDL-C values were significantly (p<0.05) increased by combination of soaking and fermentaion processes corrected to soaked bran and fermented bran diets. Pectin had a similar behviour to treated bran diet in a remarkable decrease of blood TC values in comparison with fiber-free diet. It is concluded that preparation of wheat bran foods by soaking or/and fermentation improve some physiological characteristics of insoluble fibers, including the cholesterol–lowering ability (particularly total cholesterol TC and low-density lipoprotein cholesterol LDL-C).

Abstract: The effect that dipping green pepper (Capsicum annuum, L.) in natural lemon juice followed by blanching had on the rate of the pepper chlorophyll color retention was studied. Dipping green pepper in natural lemon juice immediately after blanched with chloride salts of copper, zinc and magnesium decreased the degradation of chlorophyll after 2 weeks of storage by 13.6, 31.7 and 74.3%, respectively. The minimal loss in chlorophyll of green pepper treated with copper chloride is attributed to the rapid chelating of the copper complexes and higher heat and acid stability compared to zinc that improved the green color of blanched peeper during storage. Pepper samples that blanched with different chloride salts of copper, zinc and magnesium (100 ppm) and coated with carboxymethyl cellulose (CMC) were not significantly (P<0.05) different in chlorophyll content from uncoated samples on any given days.

Abstract: This study was conducted to investigate the effect of different processing treatments in terms of soaking and fermentation of wheat bran on weight gain, accumulative food intake and food efficiency ratio in Sprague- Dawley rats. The experimental diets included casein diet (zero-bran), untreated bran diet, soaked bran diet, fermented bran diet, “soaked and fermented” bran diet and Arabic bread diet. Each group of rats (6/group) was fed one of the six prepared diets for 6 weeks. There was no significant difference (p > 0.05) in the body weight gain among all rat groups, although the rats fed soaked diet tended to have the highest weight gain in comparison with other groups. There was no significant difference in FER among all groups, although, there was a difference between groups in the accumulative food intake. Accumulative food intake (AFI) of the rat group fed soaked bran based-diet was the highest (685.6 ± 17.3 gm) among all groups whereas AFI of the rat group fed “soaked and fermented” bran-based diet was the lowest (550.0 ± 19.1 gm). Rat group fed “soaked and fermented” branbased diet had significantly lower levels (p < 0.05) of AFI than those fed untreated bran diet, soaked bran diet and white bread diet (550.0 ± 19.1, 663.4 ± 16.6, 685.6 ± 17.3 and 629.8 ± 28.4 gm respectively). Accordingly, the AFI of the rat group fed soaked bran diet was significantly higher (p < 0.05) than those fed casein and fermented diet (685.6 ± 17.3, 598.4 ± 9.2 and 605.8 ± 25.6 gm respectively). It is concluded that preparation of wheat bran foods by soaking or/and fermentation improve some physiological characteristics of insoluble fibers, including the body weight changes, accumulative food intake and food efficiency ratio for 6 weeks

Abstract: Alzheimer’s disease (AD) is one of the most common neurodegenerative diseases AD is characterized by adult- onset progressive dementia, beginning with subtle memory failure that becomes more severe and is eventually in capacitating. The most common neuropathological feature of AD is the presence of neurofibrillaryt angles and amyloid deposits that form plaques and cerebro vascular accumulations. A Disdivided into familial and sporadic forms. AD is considered familial when more than one person in a family is affected, while sporadic refers to AD cases when no other cases have been seen in close family members. It has been over 100 years since the first cases of AD were described, and since then much has been discovered about the molecular nature of the disease. The genetic control of complex diseases is becoming more apparent as previously unidentified mutations in the human genome are described. As the genetic control of AD is uncovered, improved therapies may also be uncovered.

Abstract: Background: Assessing physical activity (PA) in people with multiple sclerosis (PwMS) is essential to follow-up the recommended PA level. The International Physical Activity Questionnaire (IPAQ) and the Incidental and Planned Exercise Questionnaire (IPEQ) have been widely used, but their validity has not been investigated previously in PwMS. Objective: This study aimed to assess the convergent and criterion validity of the IPAQ and the IPEQ in PwMS. Methods: 50 PwMS were asked to wear an Actigraph for seven days and to fill the IPAQ and IPEQ. Sedentary, moderate (MPA), vigorous (VPA) and moderate to vigorous PA (MVPA) levels were recorded. Results: Significant correlations were found between sitting time as reported by IPAQ and sedentary time as recorded by Actigraph (r = 0.41, p = 0.003), VPA by IPAQ and VPA as recorded by Actigraph (r = 0.46, p = 0.001), and MVPA by IPAQ and MVPA by Actigraph (r = 0.36, p = 0.011). IPEQ showed poor both criterion and convergent validity when compared to the Actigraph. Both IPAQ and IPEQ overestimate the intensities of PA for all the derived parameters. Conclusions: Findings of this study are important as they suggest that IPAQ in particular had convergent validity when compared to Actigraph data, but still had the problem of overestimating PA levels.

Abstract: Model Driven Engineering (MDE) have arisen as a new software development paradigm which is based on creating a set of models that represent the GUI, afterwards to generate the GUI based on these models using a series of transformations to convert the models between the different levels of abstractions, which enables the automation of the development process. This inspires us to think of a model-based testing technique that is able to test the GUIs that are designed using Model-Driven engineering by finding the proper model that can serve as a testing model. This paper proposes model-based testing technique that is derived from the design models used to develop the GUI in the Model-Driven Engineering paradigm.
