The tree is valued for its flowers, fruits, seeds and timber.

It consists in using different finite element meshes for the resolution of the different physical problems: a main fine mesh to store the results and to carry out the thermal computations, and an intermediate coarser mesh for the mechanical calculations. It makes it possible to take advantage of the localised deformations that characterize incremental processes to coarsen the mechanical mesh and consequently reduce the computational time. After presenting the main components of these Bimesh method, the building of the embedded meshes and the data transfer between the meshes, its extension for parallel calculations are discussed, before analysing the obtained speed-ups for several cogging applications, both in sequential and in parallel.

For its diagnosis, sera form 48 pregnant does were tested for Toxoplasma gondii antibodies through indirect haemagglutination test (IHAT) and modified agglutination test (MAT). Samples were collected between the periods extended from November 2006 to March 2007. The seropositive rate of pregnant does (Meet Kenana, Kalubyia Governorate, Egypt) was 35.42% (17/48). After using MAT test against T. gondii-IgM, 11 sera (22.9%) were found positive. The older animals were more frequently infected (50%) than the younger goats (26.3%). Higher prevalence in aged does was confirmed by MAT. Total T.gondii antibodies and IgM were gradually increased with the development of pregnancy. Two months post treatment with sulfademidine 33.3 %, for 5 successive days at a dose of 200 mg/kg, resulted in not only reduction of T.gondii total antibodies and IgM in all treated does, but re-modulation of T.gondii antibody titres moderately toward the mild titres, and prevention of congenital infection and abortion as well. Whereas IgM was not recorded in treated does, it was detected in the untreated ones. No abortion was recorded in all treated does, but an untreated doe delivered two dead fetuses. The delivered kids belonged to treated does were seropositive for T. gondii antibodies by using IHAT, yet they were seronegative for T.gondii-IgM by using MAT. In contrast, kids belonged to untreated does were seropositive by using both IHAT and MAT. Adequate management might be useful and essential to control toxoplasmosis in the goat herds of Kalubyia Governorate.

In this paper we investigate the influence of c-supplementation of certain subgroups on the structure of finite groups.

Lake Mariut fish quality and quantity were adversely affected eventually being unfit for human consumption due to its poor water quality. The present study was carried out to evaluate the levels of metals in the fish caught from Lake Mariut main basin and its fitness for human consumption, and the water quality after the enforcement of the Egyptian Law for Environmental Protection (Law 4/1994). Fish and water samples were collected form Lake Mariut main basin through out the period from May to December 2000. The results showed that mercury was totally undetected in fish and water samples. The levels of Fe obtained were very low compared to previous studies. Fe and Cr contents in fish flesh were higher compared to their levels in water samples. Also Cu has shown a decrease in both fish and water samples. Zn and Cd contents in water samples have decreased compared with...
