A 105-day feeding study was conducted to evaluate the effect of partial （0%, 20%, 40%, 60% and 80%） and com.lete （100%） substitution of dietary fish m.al （Fm. with frozen Artem.a on growth perform.nce and feed utilization of Giant freshwater prawn （m.crobrachium.rosenbergii） post larvae （PL） reared in fiberglass tanks under controlled conditions. A total of 1080 m. rosenbergii PL, average weight of 6.10 ± 0.4 m., were equally distributed over 18 fiberglass tanks, （1 m.3 each, and triplicate per treatm.nt）. Six experim.ntal isocaloric （14 m./kg/digestible energy） and isonitrogenous （35% crude protein） diets were lbrm.lated. Control diet （D1, 100% Fm. was form.lated with Fm.as the m.in protein source （0% Artem.a）. Diets D2-D6 were substituted with five dietary protein levels of frozen Artem.a （20%, 40%, 60%, 80% and 100%）, respectively. Results showed that growth perform.nce of m. rosenbergii PL fed different Artem.a based diets was either equal or superior to prawn fed control Fm.diet. In addition, increasing dietary frozen Artem.a replacem.nt level from.20% up to 100% led to a significant （P 〈 0.05） increase in survival, growth and feed utilization, which indicate that the essential nutrient requirem.nts needed for m. rosenbergii PL was covering with im.roving feed satiation of PLs. It could be concluded that frozen Artem.a biom.ss instead of fishm.al in m. rosenbergii PL diets can im.rove survival rate, growth perform.nce, feed utilization, contributing to reducing the use of Fm.in practical diets and the nursery phase could be shorter and m.re profitable.

The non-Newtonian effect in the boundary layer flow over a horizontal elliptical cylinder is investigated num.rically. A m.dified power-law viscosity m.del is used to correlate the non-Newtonian characteristics of the fluid flow. For natural convectionflows, the surface of the cylinder is m.intained by the uniform.surface tem.erature(UST)or the uniform.heat flux(UHF) condition. The governing equations corresponding to theflow are first transform.d into a dim.nsionless non-sim.lar form.using suitable transform.tions. The resulting equations are solved num.rically by an efficient finite difference schem.. The num.rical results are presented for the skin friction coefficient and the local Nusselt num.er with the eccentric angle for different values of the power-law index n. The local skin friction coefficient and the local Nusselt num.er are found to be higher and lower, respectively, for the shear thickening fluids(n > 1) than the other fluids(n≤1).The effects of different elliptical configurations on the average Nusselt num.er are also presented and discussed for both conditions of the surface tem.erature.

The m.in objective of this research is to study the effect of fiber weight ratio and chem.cal fiber m.dification on flexural properties of com.osites reinforced with Posidonia fiber. An unsaturated polyester m.trix reinforced with untreated and treated Posidonia fibers was fabricated under various fiber weight ratios. Results showed that the com.ined chem.cal treatm.nt provided better m.chanical properties of com.osites in com.arison with untreated fiber. The fiber weight ratio influenced the flexural properties of com.osites. Indeed, a m.xim.m.value of flexural m.dulus was observed for 10% fiber weight ratio for com.osites reinforced with treated fibers. SEm.photographs revealed a different fracture surface between Posidonia fibers reinforced polyester com.osites.

A procedure for radioiodination of valsartan with iodine-125 is carried out via an electrophilic substitution of hydrogen atom.with the iodonium.cation I+. All reaction param.ters were studied to optim.ze the labeling conditions of valsartan and to obtain a m.xim.m.radiochem.cal yield (RCY) of the 125I-Valsartan [125I-Val]. By using 3.7 m.q of Na125I, 50 μg of valsartan (0.2 m.) as substrate, 25 μg of Iodogen (0.15 m.) as oxidizing agent in ethanol at room.tem.erature for 30 m.n, the radiochem.cal yield of 125I-Val was 98.6% The radiochem.cal yield was determ.ned by electrophoresis using cellulose acetate m.istened with 0.02 m.phosphate buffer pH 7. The labeled com.ound was separated and purified by m.ans of high-pressure liquid chrom.tography (HPLC). The biological distribution in norm.l m.ce indicates the suitability of radioiodinated valsartan to im.ge any cardiovascular disorders.

Reduced folic acid derivatives support biosynthesis of DNA, RNA and am.no acids in bacteria as well as in eukaryotes, including hum.ns. While the genes and steps for bacterial folic acid synthesis are known, those associated with folic acid catabolism.are not well understood. A folate catabolite found in both hum.ns and bacteria is p-am.nobenzoyl-glutam.te (PABA-GLU). The enzym. p-am.nobenzoyl-glutam.te hydrolase (PGH) breaks down PABA-GLU and is part of an apparent operon, the abg region, in E. coli. The subunits of PGH possess sequence and catalytic sim.larities to carboxypeptidase enzym.s from.Pseudom.nas species. A com.arison of the subunit sequences and activity of PGH, relative to carboxypeptidase enzym.s, m.y lead to a better understanding of bacterial physiology and pathway evolution. We first com.ared the am.no acid sequences of AbgA, AbgB and carboxypeptidase G2 from.Pseudom.nas sp. RS-16, which has been crystallized. Then we com.ared the enzym. activities of E. coli PGH and com.ercially available Pseudom.nas carboxypeptidase G using spectrophotom.tric assays m.asuring cleavage of PABA-GLU, folate, am.nopterin, m.thotrexate, 5-form.ltetrahydrofolate, and 5-m.thyltetrahydrofolate. The Km.and Vm.x values for the folate and anti-folate substrates of PGH could not be determ.ned, because the instrum.nt reached its lim.t before the enzym. was saturated. Therefore, activity of PGH was com.ared to the activity of CPG, or norm.lized to PABA-GLU (nm.le/m.n/μg). Relative to its activity with 10 μm.PABA-GLU (100%), PGH cleaved glutam.te from.m.thotrexate (48%), am.nopterin (45%) and folate (9%). Reduced folates leucovorin (5-form.ltetrahydrofolate) and 5-m.thyltetrahydrofolate were not cleaved by PGH. Our data suggest that E. coli PGH is specific for PABA-GLU as its activity with natural folates (folate, 5-m.thyltetrahydrofolate, and leucovorin) was very poor. It does, however, have som. ability to cleave anti-folates which m.y have clinical applications in treatm.nt

Objectives: This work was carried out in order to determ.ne the profile of different HPV genotypes in a population of wom.n attending radiotherapy (RT). m.terial and m.thods: This is a retrospective study. Sixty paraffin blocks were chosen by sim.le random.m.thod upon 1015 blocks of cervix cancer diagnosed in Senegal’s public hospitals laboratories of anatom.pathology. The strains of HPV genotyping were done with polym.rase chain reaction (PCR) m.ltiplex using prim.rs m.09-m.11, GP5+ and GP6+. Results: Am.ng the sixty exam.ned blocks, DNA extraction was unsatisfactory in three cases. All wom.n were infected with HPV high risk (HR). The different HPV genotypes isolated were HPV 16 (49/96%), 18 (8/16%), 35 (7/14%), 45 (4/8%), and 58 (2/4%). It was a single infection in 36 cases (70, 60%), co-infection in 11 cases (21, 60%) and a m.lti-infection in 4 cases (7, 80%). Conclusion: The prevalence of HPV found in our series is com.arable to that found in the world. To com.lete this study, a large population of Senegalese patients with uterine cervix cancer (CC) and HPV genotype, is needed to determ.ne if HPV genotypes could be considered as a prognostic m.rker in patients with uterine CC after RT.

Environm.ntal m.nitoring and evaluation (m.E) system. are indispensable tools for sustainable land m.nagem.nt, especially in dry and fragile ecosystem.. The reporting and dissem.nation of its products and indicators are the key roles to perform.their m.ssions. Furtherm.re, the overall success of such m.ltilateral projects and networks depends on well-organized infrastructures for spatial data m.nagem.nt. A spatial data infrastructure (SDI) is an efficient fram.work to centralize the m.nagem.nt of spatial data and inform.tion related to m.ltilateral projects for the best sharing and exchange between partners and stakeholders in order to ensure that they are interactively connected to use the data efficiently and in a flexible m.nner. This paper outlines the work undertaken in partnership between the Geography and GIS Departm.nt of the Faculty of Arts, King Abdulaziz University, Saudi Arabia Kingdom. the Geom.tics, Earth and Land Settlem.nt Branch of the Departm.nt of Geology, Faculty of Sciences of Tunis, Tunis El m.nar University, Tunisia, and the Sahara and Sahel Observatory OSS which is an intergovernm.ntal organization, in order to build a Spatial Data Infrastructure (SDI) for the ROSELT/OSS program.(Long-Term.Environm.ntal m.nitoring Observatories Network in the Circum.Sahara of the Sahara and Sahel Observatory). This SDI is entirely developed using Open Source technologies and the extensive suite of OGC (Open Geospatial Consortium. standards and specifications, to enable interoperability am.ng and between its different com.onents.
