Abo-EL-Sooud, K., and L. AL-Anati, "Pharmacokinetic Study of Flunixin and its Interaction with Enrofloxacin After Intramuscular Administration in Calves", Veterinary World, 2011. Abstract

The Pharmacokinetic aspects of flunixin (FL) administered alone and in combination with enrofloxacin (EN), were studied in clinically healthy calves. The experiments were performed on two groups: FL alone {2.2 mg/kg, intramuscular (IM)}, and combination of FL (2.2 mg/kg, IM) and EN {2.5 mg/kg, IM}. Plasma concentrations of FL were determined using High Performance Liquid Chromatography (HPLC) method. Moreover, the effects of FL alone or in combination on liver and kidney functions were also assessed. Flunixin was rapidly absorbed intramuscularly with a half-life of absorption (t1/2ab) of 0.094 h and the peak plasma concentration (Cmax) was 1.27 g/mL was attained after 0.49 h (Tmax).

El-Banna, H. A., and H. El-Zorba, "Pharmacokinetic of Florfenicol (Water Soluble Formulation) in Healthy and Pasteurella Infected Broiler Chickens", Journal of American Science, 2011. Abstract

Florfenicol has been approved in the European Union for use in cattle and pigs as an injectable solution for treatment of respiratory diseases in cattle through injection .But now, it was introduced in some countries as an oral solution for the treatment of several poultry diseases. The aim of the present study is to describe the Pharmacokinetics of florfenicol (water soluble formulation)in broiler chickens after either a single intravenous and oral administration (by a dose of 30 mg/kg-1 body weight). Meanwhile, comparing its disposition in control healthy and Pasteurella-infected broilers. Following the IV administration of the drug in healthy and diseased birds, the drug plasma concentration declined in a biphasic pattern. The maximum plasma concentration of florfenicol in control healthy and diseased was reached one hour after its oral administration. But the peak level detected in control broilers was higher than that detected in infected birds. Conclusion: Data of the present study showed that volume of distribution, total body clearance in infected birds were higher than that determined in healthy ones. On the other hands, systemic bioavailability were significantly lower (F %,55.6 %) in diseased broiler compared to values determined in healthy ones (F % ,71.5).

Basta, F. F., A. E. Maurice, L. Fontbot, and P. - Y. Favarger, "Petrology and geochemistry of the banded iron formation (BIF) of Wadi Karim and Um Anab, Eastern Desert, Egypt: Implications for the origin of Neoproterozoic BIF", Precambrian Research, 2011. Abstract

Banded iron formation (BIF) is exposed among the Precambrian rocks in the Wadi Karim and Um Anab areas in the Eastern Desert of Egypt. The BIF conformably alternates with Neoproterozoic arc metavolcanic rocks, which comprise metabasalts and mafic to intermediate metapyroclastic rocks. The BIF of Wadi Karim belongs to the oxide and mixed carbonate-oxide facies, while that ofUmAnab belongs to the oxide facies only. Iron bands are generally composed of iron-rich mesobands rhythmically alternating with jasper, chert or carbonate mesobands as in the Wadi Karim area, or chert mesobands as in the Um Anab area. The BIF of Wadi Karim is composed essentially of magnetite, hematite and microcrystalline quartz, in addition to ankerite in the carbonate-bearing bands, while that ofUmAnab is composed of magnetite and microcrystalline quartz.

Amin, A. S., R. H. Hamouda, and A. A. A. Abdel-All, "PCR Assays for Detecting Major Pathogens of Mastitis in Milk Samples", World Journal of Dairy & Food Sciences, 2011. Abstract

Bovine milk samples were collected from cases of clinical and sub-clinical mastitis, respectively andexamined bacteriologically and by simplex and multiplex PCR assays for detection of Staphylococcus aureus,Escherichia coli and Streptococcus agalactiae. Escherichia coli was the most common bacteria detected inthe collected samples from clinical mastitis cases followed by Staphylococcus aureus and Streptococcusagalactiae; while Staphylococcus aureus was the most common bacteria followed by Escherichia coli andStreptococcus agalactiae in samples collected from sub-clinical mastitis cases. Compared with the culturalmethod, the simplex and multiplex PCR assays are less time consuming. It took less than 24 hours to becompleted, while identification of bacteria to the species levels by conventional microbiological and biochemical

Ahmed, M. A., S. T. Bishay, and E. -dekS. I. G. nd Omar, "Part II", Journal of Alloys and Compounds, 2011. Abstract

NixMn0.8?xMg0.2Fe2O4; 0.1 ? x ? 0.35 was prepared by standard ceramic technique at sintering temperature 1200 oC using heating / cooling rate 4 ?C/min. The samples were irradiated by Nd YAG pulsed laser with energy of the pulse 250 mJ. X-ray diffractograms reveal cubic spinel structure for all the samples before and after laser irradiation. After laser irradiation, better crystallinity was obtained in a form of an increase in the calculated crystal size. This increase was discussed as due to the change in the valence of some ions like Fe3+, Ni2+ and Mn2+. The conductivity of all the investigated samples decreases after laser irradiation and becomes temperature independent for a wider range than that before irradiation. Accordingly, these ferrites are recommended to be useful in electronic devices.

Sweilam, N. H., M. M. Khader, and R. F. Al-Bar, "Parameter Expansion Method for Viscoelastic Motion with Fractional Order Damping", Nonlinear Sci. Lett.A, 2011. Abstract

Fractional order partial differential equations are generalizations of classical partial differential equations. Increasingly, these models are used in applications in such as fluid flow, finance and others. This paper studies analytically a viscoelastic motion, which can be described by a fractionaldifferential equation. The parameter expansion method is adopted, and the result shows that oneiteration is sufficient to obtain a highly accurate solution, which is valid for the whole solutiondomain. The effect of fractional order on the amplitude-frequency behavior of the oscillator is alsoanalysed.

Shoukry, M. M., and A. A. El-Sherif, "The palladium(II)-picolylamine promoted hydrolysis of amino acid esters; kinetic evidence for inter- and intramolecular mechanisms", Progress in reaction kinetics and mechanisms., 2011. Abstract

The hydrolysis of amino acid ester is promoted by the palladium(II) complex [Pd(Pic)]2+ (Pic = 2-picolylamine). The reaction has been studied by pH-stat technique. The overall PdII chelate promoted hydrolysis of the amino acid esters as glycine and alanine ethyl esters may be accounted by inter- and intramolecular mechanisms. The kinetic data for histidine and methionine methyl esters are fitted assuming that hydrolysis proceeds by intermolecular mechanism only. The rate enhanecement compared with the free ester is discussed in terms of the structure of the complex. Activation parameters associated with the hydrolysis have been determined and discussed.

Ghani, N. A. T., and A. M. Mansour, "Palladium (II) and Platinum (II) Complexes Containing Benzimidazole Ligands: Molecular Structures, Vibrational Frequencies And Cytotoxicity", J. of Molecular structure, 2011. Abstract

(1H-benzimidazol-2-ylmethyl)-(4-methoxyl-phenyl)- amine (L1), (1H-benzimidazol-2-ylmethyl)-(4-methyl-phenyl)-amine (L2) and their Pd(II) and Pt(II) complexes have been synthesized as potential anticancer compounds and their structures were elucidated using a variety of physico-chemical techniques. Theoretical calculations invoking geometry optimization, vibrational assignments, 1H-NMR, charge distribution and molecular orbital description HOMO and LUMO were done using density functional theory. Natural bond orbital analysis (NBO) method was performed to provide details about the type of hybridization and the nature of bonding in the studied complexes. Strong coordination bonds (LP(1)N11??*(M-Cl22)) and (LP(1)N21? ?*(M-Cl23)) (M = Pd or Pt) result from donation of electron density from a lone pair orbital on the nitrogen atoms to the acceptor metal molecular orbitals. The experimental results and the calculated molecular parameters revealed square-planar geometries around the metallic centre through the pyridine-type nitrogen of the benzimidazole ring and secondary amino group and two chlorine atoms. The activation thermodynamic parameters were calculated using non-isothermal methods. The synthesized ligands, in comparison to their metal complexes were screened for their antibacterial activity. In addition, the studied complexes showed activity against three cell lines of different origin, breast cancer (MCF-7), Colon carcinoma (HCT) and human heptacellular carcinoma (Hep-G2) comparable to cis-platin.

Amer, H. M., H. M. Elzahed, E. A. Elabiare, A. A. Badawy, and A. A. Yousef, "An Optimized Polymerase Chain Reaction Assay to Identify Avian Virus Vaccine Contaminationwith Chicken Anemia Virus", J Vet Diag Invest, 2011. Abstract

The use of embryonating chicken eggs in preparation of avian virus vaccines is the principle cause for contamination with Chicken anemia virus (CAV). Identification of CAV in contaminated vaccines relies on the expensive, tedious, and time-consuming practice of virus isolation in lymphoblastoid cell lines. The experience of the last 2 decades indicates that polymerase chain reaction is extending to replace most of the classic methods for detection of infectious agents. In the present report, a simple, rapid, and accurate polymerase chain reaction method for detection of CAV in poultry vaccines is described. Oligonucleotide primers homologous to highly conserved sequences of the VP1 gene were used to amplify a fragment of 676 bp. The developed assay was specific for detecting CAV from different sources, with no cross reactivity with many avian viruses. No inter- and intra-assay variations were observed. The analytical sensitivity of the test was high enough to detect 5 TCID50 (50% tissue culture infective dose) of the virus per reaction; however, different factors related to the vaccine matrix showed considerable effects on the detection limit. In conclusion, this method may represent a suitable alternative to virus isolation for identification of CAV contamination of poultry virus vaccines.

Galal, A., N. F. Atta, and S. M. Ali, "Optimization of the synthesis conditions for LaNiO3 catalyst by microwave assisted citrate method for hydrogen production", Appl. Catal., 2011. Abstract

LaNiO3 was prepared by microwave assisted citrate method. The effect of the synthesis condition such as, the operating microwave power and the microwave irradiation time, on structural, surface and catalytic properties was investigated by XRD, SEM, Tafel linear polarization and impedance measurements. The XRD results suggested successful incorporation of Ni3+ at the La3+ cations sites confirming the formation of the hexagonal distorted rhombohedral perovskite phase of LaNiO3 at all the investigated microwave operating powers and irradiation times. The average particle size ranges between 18 and 32 nm. The largest surface area (ca. 25 m2 g?1) and the highest catalytic activity for LaNiO3 prepared by the microwave assistant-citrate method toward the hydrogen evolution reaction (HER) were obtained at an operating microwave power of 720 W and increased by increasing the microwave irradiation time. In addition, the reaction order, the activation energy and the reaction mechanism were identified.

Abdel-Gawad, H. I., "On Multiperiodic and Multisoliton Solutions Toevolution Equations with Applications", Eur. Phys. J. Plus, 2011. Abstract

The existence of multiperiodic and multisoliton solutions for parabolic one-dimensional scalarand vector equations is studied. It is shown that these solutions exist for a scalar equation if it is completelyintegrable and linearizable, while they exist for vector equations when they are completely integrable. Thegeometric structure of the solutions is similar to that of multidimensional equations. As applications, vector

EL-SHEMY, H. A., "Nutritional Value of Soybean Meal", InTech, 2011. Abstract

Protein feeds in the European Union (EU) cover only 25% demand for protein, what oblige the particular members to import feeds with a high protein content, where the main place have soybean meal. The share of this feed in total quantity of feeds utilization in EU is about 9%. Yearly consumption of soybean meal in EU is about 32mln ton, from what 5.6% it falls on Poland (Rynek Pasz, 2010). Poland, as another countries, is importer of protein feeds, mainly soybean meal.

Sweilam, N. H., W. Mahmoud, and E. K. Rawy, "Numerical Study of Some Systems of Linear Algebraic Equations with Noise Related to Boundary-value Problems for Laplace", Studies in Nonlinear Sciences 2 (2): 60-69 (2011), 2011. AbstractCU-PDF

We investigate two stable methods for solving the system of linear algebraic equations arising
from plane, singular boundary-value problems for Laplace’s equation for rectangular domains [1, 21]. The
dynamical systems method and the variational regularization method are applied to derive stable solutions
for these systems, and the results are compared with those obtained from the QR-factorization technique
contaminated with noise. The results put in evidence the difficulties that may arise from the use of the QRfactorization
method due to instability.

Sweilam, N. H., M. M. Khader, and F. M. Atlan, "Numerical Studies for Singularly Perturbed Convection Reaction DiffusionProblems in Two Dimensions", Research Journal of Mathematics and Statistics, 2011. Abstract

In this study, we study the numerical solutions of singularly perturbed convection-reaction-diffusionproblem over a square. Two different approaches are used to study the problem namely: Finite Element Method (FEM) based on a posteriori error estimate, and Variational Iteration Method (VIM). In this study, we use theadaptive h-refinement based on the a posteriori error estimate. Numerical simulation for the solution of theproposed problem using FEM and VIM is given. From this simulation we can found that the finite elementmethod gives the solution with excellent agreement compared with the exact solution. Also, it's found that VIMis invalid for some values of the perturbed parameter g, but FEM overcome on this shortcoming.
