The technologies in the field of renewable energy are used also to improve the ventilation and cooling in buildings by using the solar chimney and heat exchanger. This study addresses the design, construction and testing of a cooling system by using the above two techniques. The aim was to study the effects of weather conditions on the efficiency of this system which was installed in Baghdad for April and May 2020. The common weather in these months is hot in Baghdad. The test room of the design which has a size of 1 m3 was situated to face the geographical south. The test room is thermally insulated and connected to a solar chimney which generates a convection current to draw the air out of the room through a heat exchanger. The heat exchanger was submerged in a water tank of 2 m length, 1 m width and 1 m height. It was...

This research includes defining Binaural Beats, proving their existence, listing the positive and negative impacts of Binaural Beats, and assessing the existing UAE and UK cyberlaws, to evaluate the existence of regulations and laws addressing the use of Binaural Beats. This research includes the impacts of Binaural Beats in the Healthcare, Education, Entertainment, IT Security, and Creativity fields. Moreover, this research does not address digital drug devices that are meant to replace routine medical tablets found at pharmacies and medicine factories. Though there is no huge amount of primary data, it has significant amount of analysis of secondary data from peer reviewed articles and thus the findings have a credible ground. As less research has been done in this field, the results could be of value to researchers to extend its findings further.

Despite frequent outbreaks and endemic transmission being reported in the Middle East and North Africa (MENA), seroprevalence studies of WNV in Qatar are highly lacking. Aim: This study aims to investigate the actual prevalence of WNV among local and expatriate communities in the Qatar using a large sample size of seemingly healthy donors. Method: A total of 1992 serum samples were collected from donors of age 18 or older and were tested for the presence of WNV antibodies. Serion enzyme-linked immunosorbent assay (ELISA) commercial microplate kits were used to detect the presence of the WNV IgM and IgG. The seropositivity was statistically analyzed using SPSS software with a confidence interval of 95%. Results: The seroprevalence of anti-WNV IgG and IgM in Qatar was 10.3% and 3.4%, respectively. The country-specific seroprevalence accordin...

The purpose of this paper is to investigate some new results (up to our knowledge) on the concept of weak essential submodules which introduced by Muna A. Ahmed, where a submodule N of an R-module M is called weak essential, if N ∩ P ≠ (0) for each nonzero semiprime submodule P of M. In this paper we rewrite this definition in another formula. Some new definitions are introduced and various properties of weak essential submodules are considered.

This brings the necessity to make research works on character recognition of the English alphabet not only recognizing measure and evaluate the performance of algorithms we used. A number of algorithms have been proposed for English character recognition such as a support vector machine, hidden Markov model, and neural network. In this research, the design and implementation of a character recognition system for English characters using artificial neural networks and template matching are presented. The complete system employs image acquisition, preprocessing, character segmentation, and classification and recognition. Finally, compare the performance of ANN and template matching algorithms. A data was an MNIST dataset taken from the NIST database. Overall, a...

The overall objective of the research is to improve the productivity of home gardens owned and managed by poor women in rural rain-fed semi-arid areas of Sudan adversely affected by climate change. The area of study is located in some villages of western Sudan where biogas units were installed in some households. The effluent of biogas units were used as organic fertilizer in women garden. The area allocated for each garden was divided into plots and subplots (as replicates) for application of different concentration of the fertilizer. Two types of vegetables were cultivated randomly, these were Okra" Abelmoschus esculentus L. Moench" and Jew mallow" Corchorus olitorius L." as preferred by the women. The experiment covered two seasons. Applied fertilizer concentrations were 0 m3, 0.5 m3, 1 m3, and 1.5 m3 per hectare. MSTATC and STATISTIX8 program were used for data analysis. Results showed significant increase in yields for both vegetables, except Jews mallow in the first season. Okra yield increased from 0.93 ton/ha fresh green pods to 1.4 ton/ha with 1.5 m3 fertilizer in season one. In season two, okra increased from 0.92 ton/ha to 1.38 ton/h with 1.5 m3 fertilizer application. In season two, Jew’s mallow yield increased from 13.15 ton/ha to 21.06 ton/ha with 1.5 m3 fertilizer application. Combined analysis of variance indicated that there were significant differences among treatments for all studied traits in Okra and Jews mallow. The study insure optimum yield of Okra and Jew mallow area during off-season and high dose from biogas byproduct is recommended.

Study Design: Fourty-five sections of pneumonic lungs from one humped camels with different sex and ages ranging from (6 months-15 years) and originated from different states of the Sudan including Kassala, AlGadarif, Kordofan and Darfur, were subjected to bacteriological and histopathological studies.

Dietary treatment rations were formulated to replace groundnut cake by guar germ in a basal diet containing (%): sorghum grain, 30; groundnut hulls, 10; wheat bran, 10; molasses, 9 and common salt 1. Guar germ was included at different percentages: 0-ration A, 10-ration B, 20-ration C, 30-ration D and 40-ration E. Dry matter intake (g/kg BW) was significantly increased at inclusion of guar at levels of 20 or 30%, but significantly depressed at other levels. Digestibility of organic matter and crude protein was significantly improved by inclusion of guar at any level. That of crude fibre, however, was increased only at 30 and 40% guar levels. Disappearance of dry matter from nylon bags was almost complete within 24 h for all rations. Body weight gains increased slightly at all levels of guar inclusion in the diet. Except for the 20% level, the feed conversion ratio was also improved but this was not proved statistically. The best animal performance was obtained in response to including 30% guar in the diet.

Retrospective, noncomparative, interventional case series. Thirty-five patients with BSRC evaluated at the Ocular Immunology and Uveitis Service of the Massachusetts Eye and Ear Infirmary from 1980 through 2003. Data on age, gender, follow-up time, delay to diagnosis or referral, treatment before and during follow-up, complications of BSRC or treatment, Snellen visual acuities (VAs), and electroretinograms (ERGs) were recorded from patient charts. Disease progression as determined by Snellen VAs and serial ERGs, ocular complications of BSRC or corticosteroids, and complications of systemic IMT. Twenty-eight patients with a mean follow-up of 81.2 months were included. None of the patients had sufficient control of their inflammation before referral. All patients were treated with corticosteroid-sparing systemic IMT at some point du...

The comprehensive ophthalmologist plays a key role by not only making the diagnosis but also by monitoring inflammatory status to guide systemic therapy. If left untreated, the disease has a high likelihood of causing blindness and death. Adamantiades-Behcet disease with retinal involvement is now considered an absolute indication for systemic immunomodulatory therapy. The diagnostic signs, potential complications, and treatment modalities currently available for ocular Adamantiades-Behcet disease are reviewed.
