Floristic composition and soil characters in representative habitats of the southern Nile Deltaregion in Qalyubia were analyzed in terms of habitat variations and species diversity. A totalof 90 sites were surveyed and nineteen environmental factors were recognized in four main habitats: canal banks, cultivated lands, waste lands and sandy plains. Basic statistical treatments were established by using SPSS v. 10.0. The produced data were subjected to cluster analysis by using MVSP v. 3.1; indirect and direct ordination methods i.e. Detrended and Canonical Correspondence analyses, respectively by using CANOCO v. 4.5. A total of 164 species representing c. 7.7% of the Egyptian plant species were recorded and their life-form spectrum was identified. The majority of species were belonging to the families: Gramineae, Compositae, Leguminosae and Cruciferae.

We present the SUSY QCD corrections to the production of light neutral MSSM Higgs boson with a pair of supersymmetric scalar partners of the top quark at next-to-leading order at LHC. We study the dependence of the lowest order total cross section on both the renormalization/factorization scale and the Higgs mass in the framework of minimal supergravity, taking the point SPS1a as a benchmark, for the numerical calculations. The dependence of the total cross section is strong. Including the NLO SUSY QCD corrections significantly reduce and stabilize the dependence of the lowest order total cross section on the renormalization/factorization scale.

Two groups of buffalo calves were infected with Sarcocystis fusiformis sporocysts. Animals of the first group received each 5 X 10(5) sporocysts, those of the second group 5 million sporocysts. All calves were clinically normal during 6 weeks after infection. Minor changes were observed in the blood cytology, serum alkaline phosphatase, glutamic oxalacetic transaminase, glutamic pyruvic transaminase, total proteins, urea and glucose of infected buffalo calves.
