BIOSORPTION OF RADIOACTIVE ELEMENTS FROM PHOSPHOGYPSUM BY SACCHAROMYCES CEREVISIAE
Phosphogypsum (PG) is an important industrial by-product derived from phosphoric acid and phosphate fertilizer manufactures by dehydrates process. Using Saccharomyces cerevisiae as a biosorbant for uranium (U), thorium(Th) and radium (Ra) from (PG) by Appling different carbon sources such as maltose, sucrose, starch, lactose, fructose and glucose. Starch, maltose and fructose media give most uranium biosorption capacity (13, 13 and 14 ppm) while in sucrose and glucose media give (20 and 22 ppm). Maltose and starch media give the highest thorium biosorption capacity. At the same time sucrose and glucose give moderate biosorption.

PREVALENCE OF EXTENDED SPECTRUM ß-LACTAMASE PRODUCING E. COLI ISOLATED FROM IN-PATIENTS AND OUT-PATIENTS IN ZAGAZIG UNIVERSITY HOSPITALS
This study was done on 143 patients (75 in-patients and 68 out-patients) in Zagazig University Hospitals who were suspected to have urinary tract infections (UTIs). Their ages ranged from 12 to 61years. One hundred and twenty four of urine samples that collected from patients yielded positive culture on MacConkey’s agar. The identification of isolates was done by biochemical tests and confirmed by automated Vitek 2 system. The results showed that E. coli was the most causative organisms of UTIs 44 isolates (35.4%). Antimicrobial susceptibility test by modified Kirby-Bauer disc diffusion method was performed to select multi drugs resistant (ESβL) production according to the Clinical and Laboratory Standards Institute (CLSI) recommendation. The PCR technique was applied to detect the ESβL genes that responsible for the resistance, it was found that the TEM gene was the predominate gene (100%) amongst ESβL E. coli followed by SHV (90%) but CTX-M gene was absent. The coexistence of more than one type of β-lactamase enzymes was detected and represented (30%) of ESβL E. coli. From these results we can concluded that the Prevalence of ESβL producing E. coli was (22.7%) among E. coli isolates. TEM and SHV genes were the most frequent genes and the coexistence of ESβL, AmpC, OXA-1 was detected in (30%) of isolates.Keywords: ESBL, UTI,

ISOLATION AND IDENTIFICATION OF BACILLIUS SUBTILIS FROM FISH FARMS WATER AND EVALUATION OF ITS BIOREMEDIATION EFFECT AGAINST HEAVY METALS (CADMIUM AND CUPPER)
High concentrations of some heavy metals (cadmium (Cd) and cupper (Cu) were found in industrial and sewage water that supplied El Manzala fish farms in Egypt. The metal tolerant bacterial strain Bacillius subtilis was isolated and identified morphologically and biochemically followed by 16S rRNA gene sequence analysis. The minimum inhibitory concentrations of Cd and Cu against B. subtilis that were (6 and 20) mg/l, respectively. In the presence of sub lethal concentrations of Cd and Cu, the B. subtilis strain showed an obvious metal removing potential. The environmental conditions as pH value and incubation temperature were studied to estimate the more efficient up-taking of Cd+2 and Cu+2, ions. The maximum uptake (5 and 10) mg/l of Cd and Cu achieved at pH7and 8 for at (25- 30)ºC, while pH 5 and 9 and incubation temp10 and 40ºC showed the lowest Cd+2 and Cu+2 sorption by bacterial biomass, respectively the obtained results could be an advantage for large scale treatment of contaminated sites.

USE OF PROBIOTIC ACID BACTERIA FOR THE CONTROL OF MULTIDRUG RESISTANT BACTERIA ISOLATED FROM CLINICAL INFECTIONS
This study was carried out to evaluate the microbial infections in natural way and reduce the antibiotic resistance. One hundred bacterial isolates were collected from clinical specimens of patients suffering from bacterial infection (55 females and 45 males). The bacterial isolates were obtained from 8 different specimens with the following percentage representations: urine (30.58 %), blood (20%), abscess (20%), wound (9.41%), throat and tube swab (5.88%), ear discharges (5.88%), vaginal swabs (5.88%) and eye swab (2.35%).The results showed that (29.41%) Escherichia coli, (23.53%) Klebsiella pneumoniae, (17.65%) Staphylococcus aureus, (15.29%) Pseudomonas aeruginosa, (8.24%) Proteus vulgaris, (5.88%) Acinetobacter baumannii. Among 17 antibiotics tested, meropenem, a carbapenem antibiotic, was the most effective drug against most of the gram-negative and gram-positive bacteria. Detection of biofilm by two different methods show that most of isolates were multidrug resistant. Three species of lactic acid bacteria namely L.acidophilus (DSM20079), L.plantarum (DSM20174) and L.salivarus (DSM20555) were used for reducing the microbial infections. Bacteriocins were isolated from MRS broth culture of these lactic acid bacteria through the precipitation method using 1N HCL and were tested against different pathogenic bacteria. Antibacterial activity of bacteriocins extracted from L. acidophilus (DSM20079) showed maximum activity against most isolated bacteria as compare to others. Also, L.salivarus (DSM20555) have the highest activity against Methicillin-resistant Staph aureus. The present study has showed the antibacterial role of bacteriocin isolated from lactic acid bacteria can be used for treatment variety of human diseases.

Investigations onto the Recovery of Uranium and Rare Earth Elements from High Sulfate Concentrations Leach Liquor of Abu Hamata Sandy claystone ore material via Anion-Exchange Resin process
Excess of free sulfate anions in a sulfate leach solution became an offending object for uranium recovery by using Amberlite IRA400 anion exchange resin. This is because, not only uranium U loading efficiency is reduced significantly, but also the selectivity for the uranyl sulfate complex, [UO2(SO4)3]4 - over ferric sulfate complex, [FeO (SO4)]-, is reduced.The present study concerned with the feasibility of using Amberlite IRA400 anion exchange resin for effective recovery of uranium from highly concentrated sulfate solution of Abu Hamata sandy claystone ore sample. The latter solution was found assaying 0.45 g/L and 26 g/L of U and SO4 --, respectively, together with 0.32 g/L, 0.05 g/ L, 0.008 g/L and 2.3 g/L of rare earth elements, (REEs), V, B as well as Cl-, respectively. Such solution was treated with solid CaCO3 at different pH values ranged from 1 upto 3 for precipitating the excess free sulfate. The obtained results indicate that, U extraction efficiency has been highly improved from 48.4% up to 94.4% at pH 1.8.

EXTRACTION OF URANIUM USING ALAMINE336 IN KEROSENE FROM SULFATE SOLUTION OF ABU-HAMATA SANDY CLAYSTONE ORE SAMPLE, SOUTHWESTERN SINAI, EGYPT
The present study is concerned with the feasibility of using organic solvent, Alamine336 in kerosene to extract U from sulfate leach liquor of Abu-Hamata sandy clay stone ore sample. The prepared sulfate leach liquor assays 0.45g/L of U with achieved leaching efficiency of 98.9%. The obtained results indicate that U extraction efficiency depends mainly on Alamine 336 concentration, strongly influenced by pH value, contact time and the organic / aqueous (O/A) ratio.Uranium in the organic phase was stripped using a solution of 1M NaCl acidified with 0.2M H2SO4 with an achieved stripping efficiency of 93.9% at A/O ratio of 1/1 and shaking time of 5min. Not less than 99% of U in the obtained U rich strip solution was directly precipitated using H2O2 solution to produce the final pure product of U3O8.

Direct Spectrophotometric Determination of Lead (II) in Industrial Samples using 1, 3-Benzenediamine, N, N'-bis(2-furanylmethylene) in Presence of Surfactant
Schiff's base are one of the excellent chelating agents that used for the spectrophotometric determination of metal ions. It was observed that 1, 3-Benzenediamine, N,N'-bis(2-furanylmethylene) (BDFM) formed a brown colored complex with lead (II) at 620 nm. Lead (II) was chelated with the Schiff's base (BDFM) in acidic medium at pH = 3.5 using acetate buffer in presence of sodium laureth sulfate (SLS) as a surfactant. The effect of time, temperature and foreign ions were studied. The stoichiometric composition of the formed complex was found to be 1:2 (metal: ligand) by Job's method of continuous variation. Beer's law was obeyed in the range of 10-110 μg mL-1 with molar absorptivity 10.16×103 L mol-1cm-1. The proposed method was applied for the determination of lead in gasoline, solders, gutters and wastewater.

KINETICS STUDY OF ORGANIC MATTER ADSORPTION FROM HIGH STRENGTH PHOSPHORIC ACID ONTO ACID ACTIVATED SODIUM-BENTONITE
This study analyzed the structural transformations and adsorption properties of Na-bentonite clay before and after chemical activation by sulfuric and hydrochloric acids. The untreated and treated samples were characterized using Xray Fluorescence, X-ray diffraction and Fourier Transform Infrared (FTIR) Spectroscopy. The adsorptive capacities of the samples were investigated by using them to adsorb organic matter from high strength phosphoric acid. The experimental data exhibited that the clay treated with sulfuric acid caused highest organic matter adsorption capacity. The kinetic models of adsorption were analyzed by the pseudo-first order, pseudo-second order, Elovich kinetic and Morris-Weber models. The results have been indicated that the pseudo-secondorder kinetic model is more appropriate than the others for natural bentonite but for chemical activated clays pseudo-first order is fitting.

CALOTROPIS PROCERA EXTRACT (CPE) AS CORROSION INHIBITOR FOR COPPER IN NITRIC ACIDIC MEDIUM
The corrosion of copper in 2M HNO3 in the presence of calotropis procera separate has been researched utilizing, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PP), electrochemical frequency modulation (EFM) and weight loss techniques. Polarization studies demonstrated that, this extract acts as mixed- type inhibitor. Inhibition proficiency of this extract has been found to vary with concentration and temperature. The adsorption of this extract on the surface of copper from the corrosive arrangement has been found to obey Temkin adsorption isotherm. The thermodynamic parameters of copper corrosion in 2M HNO3 were resolved and discussed. The SEM examination and Atomic Force Microscopy (AFM) of the copper surface revealed that the compound prevented from corrosion by adsorption on its surfaces. FTIR results showed that the inhibition mechanism was by absorption process, through the functional groups present in the extract molecules.

DELINEATION OF STRUCTURAL PATTERNS OF SEDIMENTARY BASINS OF NORTHERN NILE DELTA, EGYPT, USED GRAVITY DATA.
The present study is an attempt to delineate the regional structural framework and basin configuration of Northern Nile Delta, Egypt by analysis of gravity map. The study area is located, between Longitude 30o 30′′ - 32o00′′ E and Latitude 31o 00′′ - 31o 48′′ N. The least square polynomial technique is used to separate the Bouguer anomaly of the study area into its regional and residual components. The second order polynomial is taken as the optimum one to achieve the regional residual separation. The structural framework of the sedimentary basins is delineated using the Euler deconvelution technique, the detected fault systems are grouped into six major tectonic trends: Mediterranean trend (E-W trend), Syrian arc trend (N 45o - 65o E trend), Najd trend (N 65o W trend), Gulf of Suez trend (N 35o - 45o W trend), Aqaba trend (N 15o - 25o E trend) and North African trend (N-S trend). The constructed depth to the basement map illustrates a huge basin located in the central part of the study area. The depth ranges from 1400 m to 10460 m.

STRUCTURAL ARCHITECTURE OF TARBOUL BASIN, SOUTHERN GULF OF SUEZ, EGYPT
The surface structural architecture basin configuration and petroleum system are important steps in studying and evaluating frontier sedimentary basins. The Tarboul basin (TH) is a typical marginal half garben at the onshore part of the southern Gulf of Suez rift. It is bounded from the west by the NW-SE striking Oligo-Miocene rift boundary fault (RBF) and from the East by the NW-SE striking Gemsa basin major bounding fault. The TH has a tripartite geometry bordered by the RBF, rift onset unconformity and the post rift unconformity. The Pre-rift strata include undifferentiated Nubia sandstones of Paleozoic-Lower Cretaceous age, Raha Formation of Cenomanian age, Wata Formation of Turonian age, Matulla Formation of Coniacian - Santonian age, Duwi Formation of Campanian age, Sudr Formation of Masstrachtian age and Thebes Formation of lower Eocene age. The synrift strata are represented by Lower Miocene Nukhul Formation and Lower-Middle Miocene Rudeis Formation. The Syn-rift packages roll into and stratigraphically thicken toward the RBF. The up dip northeastern part of the TH is characterized by a flexural faulted margin where there is an exposed monoclinal structure. Integrating surface and subsurface mapping of the monocline facilitated the prediction of the upward propagated fault that formed this structure. The TH has a SE plunging NW-SE oriented synclinal structure representing a hanging wall syncline related to the upward propagation of the RBF. The exposed Pre-Miocene rock units at the northwest part of this structure indicate the decrease in the throw of the RBF toward the onshore part of the adjoining Morgan Transfer Zone.

USE OF WELL-LOGS FOR PETROPHYSICAL EVALUATION OF ABU MADI RESERVOIR IN ABU MADI - EL-QARA - NIDOCO AREA, NORTHERN NILE DELTA, EGYPT
The objective of the present study is to evaluate the reservoir characteristics of the Late Miocene Abu Madi Formation (Abu Madi Levels II and III) at Abu Madi-El-Qara-Nidoco area, northern Nile Delta, Egypt. The study area is located between Longitude 31° 13` 48`` -31° 24` 36``E and Latitude 31° 21` 36``- 31° 37` 12`` N. Open-hole wireline log data of seven wells are used in this study. The petrophysical characteristics of the studied formation are thoroughly investigated to elucidate its hydrocarbon potentialities. The vertical variation of the petrophysical characteristics is presented as Lithosaturation cross-plots. The parameters distribution maps (shale volume, porosity, fluid saturation, net pay thickness and hydrocarbon saturation) are constructed to represent the lateral variation of petrophysical characteristics. The shale model shows that the dominant shale is mainly of dispersed and laminated types. The constructed neutron-bulk density, neutron-sonic and M-N crossplots display that the main reservoir lithology is sandstone intercalated mainly with dispersed shale and minor laminated shale in Level III and dispersed to laminated shale in Level II. It is also shown that Abu Madi Formation has poor to very good porosities range from 0.03 to 0.22 for Level II and from 0.06 to 0.19 for Level III. The most favorable places for hydrocarbon reservoirs occupy southwestern part for Abu Madi Level II reservoir and in the middle, the middle-west, the middle-east and the southeastern parts for Abu Madi Level III reservoir.

BIOTRANSFORMATION OF ORANGE PEEL ESSENTIAL OIL BY A NATIVE PENICILLIUM SPECIES ISOLATED FROM ORANGE
Microbial biotransformation is a relevant strategy to obtain high added value natural compounds under controlled environmentally friendly conditions. In this research work, the use of agro-residues (orange peel oil) in the biotransformation of D-limonene by a native Penicillium italicumAUMC13045 species isolated from decayed orange was evaluated. The chemical analysis of water-steam distilled orange peel oil was determined by Gass Chromatography (GC) and D-limonene was shown to be the predominant constituent, representing 82.87% of the total content. It was investigated that the highest α-terpineol yield was obtained by Malt Yeast Broth (MYB) medium at the second day after the first addition of orange peel oil. The highest α-terpineol selectivity obtained when bioconversion media inoculated with fungal conidia at the early stage of the exponential growth. The investigated samples gave higher α-terpineol yield when extracted by mixture of (1:1) diethyl ether and pentane.

REMOVAL OF URANIUM FROM LIQUID WASTE BY NATURAL NILE MUD
This effort deals with uranium removal from liquid waste using Natural Nile Mud (NNM). Accordingly, cost effective and simple approach to remove uranium from liquid waste by NNM was reported. The effects of shaking time, pH, the initial uranium concentration, adsorbent temperature, adsorbent amount (dose) and effect of foreign ion (iron) on the adsorption of uranium ions from liquid waste were examined. According to the results, the optimum conditions for maximum adsorption efficiency of the NNM for uranium from the solution were obtained fitted with the Langmuir and the maximum adsorption capacity was about 61 mg/g NNM.

NORMALIZING EXTENSIONS OF RIGHT G-SEMILOCAL AND RIGHT N-SEMILOCAL RINGS
The aim of this paper is to focus on two new classes of rings called right G-semilocal and right N-semilocal. These classes are a generalization of the class of semilocal rings. We also study the transfer of right G-semilocality and right N-semilocality from a ring R to its normalizing extension S and vice versa.

EFFECT OF CUTANEOUS LEISHMANIASIS ON SOME HAEMATOLOGICAL AND IMMUNOLOGICAL PARAMETERS IN PATIENTS FROM AREAS OF NORTH BAGHDAD / IRAQ
The current study was conducted to determine the effect of cutaneous leishmaniasis on some haematological and immunological parameters. 80 samples are examined from patients in areas of north Baghdad - Iraq. Patients are (40 males and 40 females), and 40 samples from healthy persons (20 males and 20 females) as a control group from December 2016 to August 2017. Results of the haematological parameters showed a significant increase in the number of red blood cells (RBC) of infected females compared to non-infected, while there is no significant difference between infected and non-infected males. Significant decrease in packed cell volume (PCV) is found in infected males, while there is no difference in infected females compared to non- infected. There is also significant decrease in haemoglobin (Hb) concentration in the infected females and males compared when compare with the control group. There was a significant decrease in the white blood cell count (WBC) in infected females, while there is no difference in males. There is a significant increase in lymphocyte and monocyte in both males and females compared to control, while there is a significant increase in neutrophil for males, and there is no difference in females. The results of immunological parameters showed that there were 62 positive for IgG cases and 18 for positive IgM cases, thus indicating 62 positive cases and 18 negative anti-nucleic antibody (ANA) cases. There was no significant difference according to the different ages, for both sexes with the result obtained for ANA. Regarding interleukin (IL-10) level there is significant difference between the ages in female and males’ groups, there is no significant difference between the sexes and the type of infections. There is a significant difference in concentration of interleukin depending on the duration of the infection

PYRIDAZINE AND ITS RELATED COMPOUNDS, SYNTHESIS OF SOME NOVEL CONDENSED PYRIDAZINES
A series of pyridazino[3,4-d][1,3]oxazin-5-one derivatives were designed and synthesized through a versatile method. Reaction of chloro-ester 1 with sodium azide has afforded azido-ester 2 which reacted with triphenylphosphine to produce compound 3; amino-ester 4 was formed upon treatment of compound 3 with acetic acid 80%; this amino-ester 4 was then hydrolyzed to the amino-acid 5 which is considered the starting material. The approach involves treatment of pyridazinamino-acid 5 with acetic anhydride, benzoyl chloride, triethylorthoformate, ethyl chloroformate, diethyl oxalate, phthalic anhydride as well as succinic anhydride to yield pyridazino[3,4-d][1,3]oxazin-5-one derivatives 6, 8, 9, 10, 11, 12 and 13. The new synthesized compounds were confirmed by their infrared, mass spectrum and 1H-NMR.
