Numbers of 300 day-old broiler chickens through a CRD design with 5 treatments, 3 replicates and 20 chicks in each pen were used to evaluate the effect of thyme (T), licorice (L), thyme + licorice (TL), and enzyme supplemented (E) diets on performance, immune and carcass characteristics. According to the results, performance traits, immune indices, and carcass traits in herbal medicine and enzyme supplemented diets were improved significantly than control diet (P ely (P abdominal fat and liver weight as indicators of lipogenesis rate were decreased in T, L, and TL diets than control or E diet significantly (P < 0.05). Immune organs such as burse and spleen weight as indicators of immune situation were increased in TL diet than other treatments significantly (P < 0.05). These findings indicated that thyme and licorice singly or in combination as organic herbal medicine can affect performance, carcass and immune characteristics. Also an improved immune organ such as burse or spleen in this study indicates that this herbal medicine can promote the immune situation and efficacy of health and livability.

Magnetoresistive properties of Ni-doped La_(0.7)Sr_(0.3)MnO_3 manganites

Rare Metals 2016年第7期35卷 551-558页

Lao.7Sr0.3Mnl_xNixO3 （x = 0, 0.025, 0.050 and 0.075） ceramics were prepared by the conventional solid-state reaction method. The partial substitution of Mn by Ni2＋ leads to a decrease in cell volume as well as a structural transition from the rhombohedral to the orthorhombic structure. Ni2＋ doping increases the electrical resistivity, decreases the semiconductor-metal transition temperature （Tms） and relatively enhances the room temperature magnetoresistance （MR）, especially in x = 0.025 and around Tins. With respect to conduction mechanism, the small polaron hopping （SPH） and the variable range hopping （VRH） models were used to ex- amine conduction in the semiconducting region.

Maternal-Fetal Hepatitis E Transmission:Is It Underestimated?

Journal of Clinical and Translational Hepatology 2014年第2期2卷 117-123页

Hepatitis E virus (HEV) is an enterically transmitted virus;and several modes of transmission have been proposed, including blood transfusion, person to person transmission, and transplacental transmission. HEV during pregnancy is asso-ciated with an unfavorable prognosis for mothers and in severe cases can cause acute fulminate hepatitis and death. Transplacental transmission of HEV usually results in unfa-vorable outcomes of pregnancy, mainly fetal loss, preterm labor, and hepatic dysfunction in neonates. In this review, we will summarize the effects of HEV on maternal-fetal health in various clinical situations.

SOLUTION OF THE RAYLEIGH PROBLEM FOR A POWER-LAW NON-NEWTONIAN CONDUCTING FLUID VIA GROUP METHOD

引用

Applied Mathematics and Mechanics(English Edition) 2002年第6期23卷 639-646页

作者： Mina B.abd-el-Malek Nagwa A.Badran Hossam S.hassan Department of Engineering Mathematics and Physics Faculty of Engineering Alexandria University 21544 Alexandria Egypt Department of Basic and Applied Science Arab Academy for Science and Technology and Maritime Transport P O Box 1029 Alexandria Egypt

An investigation is made of the magnetic Rayleigh problem where a semi_infinite plate is given an impulsive motion and thereafter moves with constant velocity in a non_Newtonian power law fluid of infinite extent. The solution of this highly non_linear problem is obtained by means of the transformation group theoretic approach. The one_parameter group transformation reduces the number of independent variables by one and the governing partial differential equation with the boundary conditions reduce to an ordinary differential equation with the appropriate boundary conditions. Effect of the some parameters on the velocity u(y,t) has been studied and the results are plotted.

Components Assignment Problem for Multi-Source Multi-Sink Flow Networks with Reliability and Budget Constraints

引用

Journal of Computer and Communications 2022年第6期10卷 99-111页

作者： Noha Nasr elden Moatamad hassan Mohamed abd el-aziz Mathematics and Computer Science Department Faculty of Science Aswan University Aswan Egypt Information Systems Department Faculty of Computer and Information Sciences Ain Shams University Cairo Egypt

System reliability optimization problem of multi-source multi-sink flow network is defined by searching the optimal components that maximize the reliability and minimize the total assignment cost. Therefore, a genetic-based approach is proposed to solve the components assignment problem under budget constraint. The mathematical model of the optimization problem is presented and solved by the proposed genetic-based approach. The proposed approach is based on determining the optimal set of lower boundary points that maximize the system reliability such that the total assignment cost does not exceed the specified budget. Finally, to evaluate our approach, we applied it to various network examples with different numbers of available components;two-source two-sink network and three-source two-sink network.

Background: Chronic venous ulcers are a serious problem for both patients and physicians. The CEAP classification(clinical manifestations(C), etiologic factors(E), anatomic distribution of disease(A), and underlying pathophysiologic findings(P)) for chronic venous disorders(CVD) was developed in 1994. Published papers on CVD use all or part of the CEAP. Micropunch grafts, which are a variation of skin grafts, have been used with great success in plastic surgery for both esthetic and reconstructive purposes. This study aimed to assess the outcomes of micropunch grafting in the treatment of chronic refractory venous ***: Patients with chronic venous ulcers who did not respond to conservative treatment for more than 6months were included in the study. All patients underwent ulcer coverage by micropunch skin grafts using a micrometer. The patients were discharged on the same day as the surgery. Micropunch skin grafts were manually counted per square centimeter intraoperatively and during follow-up using Dermlite DermatoschopeTM II Pro *** satisfaction was assessed by using a ***: Twenty patients underwent the surgery. Most of the patients were middle-aged males. The ulcers were predominantly small-and medium-sized. The mean operation time was 167.00 ± 86.01 min. After 6 months, the survival rate of the planted micrografts was 84%. Three ulcers had graft loss and two patients had an infection at the ulcer site, which was managed conservatively. The patients were followed-up for 14 ***: Micropunch grafting is a useful and convenient method for the treatment of difficult venous ulcers and can be performed on an outpatient basis.

Design and Analysis of an OSA-BR MAC Protocol for Cognitive Radio Ad Hoc Networks

引用

International Journal of Communications, Network and System Sciences 2014年第7期7卷 223-234页

作者： hassan Al-Mahdi Mohamed Wahed Safa abd el-aziz Faculty of Sciences and Arts Al Jouf UniversityAl QuryyatKSA Faculty of Computers and Information Suez Canal UniversityIsmailiaEgypt

Cognitive Radio (CR) is a new communication network paradigm introduced to solve the problems of spectrum scarcity and inefficient spectrum usage. Basically, it allows the Secondary Users (SUs) to utilize the Licensed Channels (LCs) of the Primary Users (PUs) in an opportunistic manner without causing any harmful interference to the PUs. However, there are many challenges associated with cognitive radio networks, such as the CR Medium Access Control (CR-MAC) protocols. An important issue for CR-MAC protocols is to identify whether the spectrum is licensed or unlicensed. In addition, the sudden appearance of the PU is the most important feature of the distributed CR-MAC protocols. In this paper, a multichannel CR-MAC protocol, which reacts efficiently to the appearance of the PUs, is developed. The proposed protocol is named Opportunistic Spectrum Access with backup channel and Buffered data with Resume (OSA-BR). The OSA-BR is an unaided rendezvous, asynchronous, and contention-based MAC protocol. The proposed protocol operates in heterogeneous environment, where the SUs utilize both LCs and unlicensed channel (ULs) and the activities of the Classical Users (CUs) are taken into consideration. In addition, the concept of the backup channel and the buffer with resume are introduced. The simulation results show that OSA-BR accomplishes 35% throughput gain over the SWITCH protocol and 55% over other CR-MAC protocols.
