Characterization The High Dispersion Molybdenum Oxide On Silica Surface Using XRD Technique
(Sebha University, 2010) F.A Abudelrhman, Mohmed
The X-ray powder diffraction method is thus ideally suited for characterization and identification of polycrystalline phases. The main use of powder diffraction is to identify components in a sample by a search/match procedure. Silica (SiO2) supported molybena (MoO3) catalysts at loading varying between 3 and 6 wt% were prepared by impregnating support silica (SiO2) with an aqueous solution at different acidity levels (pH = 2, 4 and 6) of ammonium hepta molybdate. After stirring for 3 h, the excess water was slowly evaporated at 100°C. Moreover, the impregnated supports were further dried at 120°C for 24 h. The products thus obtained were calcined at 700 °C for 2 h in static atmosphere of air. X-ray powder diffractogram (XRD) for support (SiO2), supported (MoO3) and different loading levels (3, 4, 5 and 6 wt% MoO3/SiO2) catalysts at different PH`s were investigated. The results clearly revealed that the formation of highly dispersed MoO3 phase on the SiO2 surface at a loading levels of 3 wt%, at pH = 2, for 4 wt%, at pH = 4 and 5 wt%, at pH = 6. This indicts that, a weaker dispersion of MoO3 on SiO2 surface at low pH. Given that, at low pH = 2 the formation of MoO3 phase crystallites was observed at 2 wt%. Whereas, at high pH = 6 the form of MoO3 crystallites was observed at 6 wt%. These results can be reorganized on the basis of the different surface chemical properties of the oxide support and nature of oxide supported.
New Approach Of Contour Approximation
(Sebha University, 2010) Ukasha, Ali Abdelrahman
This study introduced new algorithm of a method known as Trapezoid method for the contour compression. The analysed algorithm is able to approximate efficiently a set of straight segments in a near optimal way in terms of contour quality. Representations of the input contour points are in Cartesian co-ordinates which are processed in such way to obtain vertices and which some of them are chosen as the vertices of the contour polygon. The analysed algorithm has some main advantage compared to the existing methods, it is faster on implementation. The proposed algorithm is compared with Ramer method because it has best quality among well known algorithms; and with Triangle method because it’s high speedity in implementation; in addition to the Trapezoid method (I algorithm) of contour approximation. Computational time of analysed method is estimated depending on a number of numerical operations. This paper shows that the simplicity is additional distinct feature of the proposed algorithm. This work gives an overview of the system architecture, describe the compression technique, and discuss implementation aspects. Experimental results for single and multicontours images are obtained in terms of image quality, compression ratios, and image retrieval timings. It was concluded that the proposed algorithm have high compression efficiency with accepted quality for different type of contours from different languages such as Arabic and English.
The Dog – Whelk, Nucella Lapillus (L.) On The Rocky Shores Of Gower Peninsula, U.K. After The 1987 Tributyltin Restrictive Legislation.
(Sebha University, 2010) B. L. James, M. S. Mustafa
The occurrence of imposex female Nucella lapillus (L.) on the Gower Peninsula in 1992 with little development of the vas deferens (VDS) and very small relative penis size (RPS) suggests that, following the restrictive legislation for Tributyltin (TBT) in 1987, only residual levels of less than 1ng/1 remain in the sea water close to the relatively sheltered shores near the small boat Mooring, at Mumbles and near Swansea Docks. These results indicate that UK. Environmental quality target levels of less than 2 ng/1 of TBT has been achieved on the Gower Peninsular. In addition to the occurrence of the imposex females, the level of contamination on sheltered shores may increase penis bulk in males but is insufficient to (a) sterilize the females, (b) reduce population density, (c) affect the sex ratio or (d) to modify the shell characters of the dog-whelk. Some shell characteristics, however, change with variation in exposure to wave action. The more remote exposed shores appear to be free from contamination by TBT.The occurrence of imposex female Nucella lapillus (L.) on the Gower Peninsula in 1992 with little development of the vas deferens (VDS) and very small relative penis size (RPS) suggests that, following the restrictive legislation for Tributyltin (TBT) in 1987, only residual levels of less than 1ng/1 remain in the sea water close to the relatively sheltered shores near the small boat Mooring, at Mumbles and near Swansea Docks.

(Sebha University, 2010) Assad Esheewe, Mohamed A Ackacha, Naje A Saeed
The presence of toxic heavy metals such as lead in water environment, is one of the most environment problems in the developing countries. Adsorption technique is one of the effective methods were used for removal of lead ions from polluted water. In the present work, consumed green tea leaves without further treatment were used for the removal of lead ions from polluted water. Batch adsorption experiments explained that the consumed green tea leaves has a high adsorption efficiency for adsorption of lead ions onto it's surface. Several parameters affecting the adsorption process were studied such as initial pH of lead ion solutions, adsorbent concentration and contact time. Adsorption kinetics such as pseudosecond order reaction was studied. Langmuir and Freundlich models were applied for describing the adsorption process. The maximum adsorption capacity of Pb(II) onto consumed green tea leaves at 313 and 320 K were 192.31 and 138.88 mg/g, respectively.

Host Range And Host (Un)Specificity Of Different Isolates Of Polymyxa betae
(Sebha University, 2010) Homa, Ihmed
Five soil samples were taken from sugar beet growing areas in France (3), England (1) and Czech Republic (1). Sugar beet, Chenopodium album, C. murale, C. ficifolium, Portulaca oleracea, and Amaranthus retroflexus as possible hosts of specific formae speciales were sown in these samples. After six weeks roots of baiting plants were checked for the presence of P. betae cystosori. If they were not found every two weeks other plants were checked. Roots containing cystosori were harvested and homogenized in water. The homogenates were used to inoculate the same plants host in sand cultures. Using this method we obtained P. betae isolates from sugar beet and C. murale from all soil samples and two isolates from C. album. Roots of plants were used for the enrichment of P. betae population in sand. Then all host species were sown in these sands and roots of plants were checked as described above. Sugar beet and C. murale were infected in all soils. C. ficifolium and C. album were infected in three soils; A. retroflexus in one soil and P. oleracea has never been infected. On the contrary, after the enrichment of population of given isolate in sand all other hosts were always infected with two exceptional cases of A. retroflexus only. It means that there is almost no host specificity of different isolates. In different trials seeds of potential host species were sown into soil containing P. betae. The procedure was similar as described above. Some new host of P. betae were found.
Influence of Cold-storage Temperatures on Strawberry Rot Caused by Botrytis cinerea
(Sebha University, 2013) Abushaala, Faraj Ali
Thirteen fungal isolates from rotten strawberry fruits were collected from fields of Sharkia Governorate. The most frequent one was Botrytis cinerea. The susceptibility of Camarosa, Chandler, Kelia, and Sweet Charlie cultivars by B. cinerea showed that the Camarosa cultivar had the least incidence of total decay percentage at delayed cooling (4 h after inoculation), prompt cooling (1 h after inoculation), and accounted for 66.66% and 40.00% respectively. Other cultivars showed higher incidence of decay. The same pattern was observed in the severity of infection test. Prompt cooling was important for minimizing post postharvest decay of strawberries for both inoculated and non-inoculated fruits. Incidence and severity of decay were evaluated after storage for 7 d at 2˚C plus a simulated retail display period of 1 d at room temperature (20˚C).
Facile Synthesis of Thiazolidin-4-one Derivatives Incorporating Indole Moiety
(Sebha University, 2013) A. Altamamy, Hussein.
Condensation of ethyl 3-formyl-1H-indole-2-carboxylate (1) with thiosemicarbazide in ethanol gave ethyl 3-(thiosemicarbazidomethyl)-1H-indole-2-carboxylate (2). Treatment of 2 with chloroacetic acid afforded the thiazolidin-4-one derivative 3. Condensation of 3 with aromatic aldehydes gave the corresponding arylidene derivatives 4a-c. Cyclization of 4a-c with hydroxylamine hydrochloride in the presence of sodium acetate yielded thiazolidino[4,5-c]isoxazoline derivatives 5a-c. The structure of the synthesized compounds were confirmed using elemental and spectroscopic analysis.
A COMPARISON BETWEEN GLOBAL AND ADAPTIVE BANDWIDTHS USING (DPI) AND (RSC) SELECTION METHODS
(Sebha University, 2013) A.M.Mami, A.K.Abdlkder
Non-parametric regression is type of regression analysis in which functional form of the relationship response variable and the associated predictor variable dose not to be specified in order to fit a model to a set of data. There are many different methods for non-parametric regression. We have used the local polynomial kernel estimator with the optimal choice of the smoothing parameter(s).Choosing the optimal smoothing parameter(s), which is usually called the bandwidth(s), is considered to be one the most important issue when using the kernel-based estimator. Also, the optimal bandwidth(s) played crucial role to uncover the structure of the underlying data. In this paper, we use simulation approach to make comparisons between two different strategies for selecting the optimal bandwidth(s), namely the Direct plug-In (DPI) selection method and the Residual Square Criterion (RSC) method. Within the context of these two strategies of selecting the optimal bandwidth(s), there are two different settings of choosing the smoothing parameter: global (single bandwidth) or adaptive (variable bandwidths). Moreover, four different example-regression models have been used in order to smooth the mean regression functions. Several statistical properties have been investigated in the simulation study. Such study must be restrictive because of the many possibilities to be consider, we decide to consider the following three elements: The size of sample (n). Distribution of the error's (normal, exponential). The kind of Design (fixed and random).

The unmodified silica gel (for chromatography) and modified silica gel by poly acrylamide (PAAM) at optimum conditions were used to remove calcium (Ca2+) and magnesium (Mg2+) ions from aqueous solutions by the use of batch experiments at pH 10. The unmodified silica gel exhibited low percentage values about 15% and 17% for Ca2+ and Mg2+ ions removal, respectively comparing with that for modified silica gel 21.68% and 56.3% removal for Ca2+ and Mg2+ ions, respectively.
Olive branches blight in Jordan
(Sebua University, 2013) Bashabsheh, Mohammed
This disease of olive trees was noticed throughout field surveys in the north of Jordan. Olive branches show necrosis and eventual blight starting at the old pruning points, damaged branches ends and broken branches by the end of the growing season. Disease symptoms are characterized by reddish discoloration starting on one side of the affected branch and then moves downward in the cortex and the phloem making long red strip of sunken tissue. At the advanced stages the xylem underneath form that growing red discoloration becomes brown. The affected xylem tissue at first appears as a sector in the cross section and then the whole xylem inside of the branch become affected. Those symptoms were previously attributed to improper pruning practices. However this case becomes rather a phenomenon affecting large population of olive trees in the olive plantations in the north of Jordan. It is suspected that one or more pathogenic fungi prevailed throughout past seasons becoming significant on predisposed olive branches and trees. This investigation aimed to evaluate the magnitude of the disease incidence and severity and also to confirm the pathogenic agents associated with such symptoms and test there pathogenecity. At the end to evaluate all possible control methods and management measures against this disease.

Classification of html files by using Bees Colony algorithm
(Sebha University, 2013) Alarabi, Ali
From long time a lot of associates try to build database systems which could prove and performs many services. One of the project associated the information system is the classification of a data or the information. This data or information is presented in files that have different type like html. Our purpose when we chose one of these types to present a technique which may can classify these files dependent on their similarity and in a short time. The technique we going to use is a Bees Colony. The files going to use may contains texts, images, photos. So the experts always were looking for the best way to arrive or to find the exact information and to retrieve it’s quickly as possible. This information is distributed between different servers and with different languages, which give some difficulty to collect the similar pages together. So the only and easy way to arrive to this purpose is to do this work automatically. From this automatic way we got many systems of knowledge which called hypertext, hypermedia and so on, which are used in different domains like the education. Many techniques to groups the pages web are used like statistics, mathematics models. The files classified are represented by one binary matrix. After the application of this algorithm we couldn’t arrived to our purpose.
Synthesis and Biological activity of Some PyrroloPyrimidine Compounds.
(Sebha University, 2013) Mussa, Suliman Mohamed
The present work was planned to synthesize some heterocyclic compounds containing pyrrolo[2,3-d]pyrimidines. Our approach to the synthesis of the target compounds started through the hydrolysis of 6-ethylthio-4-methyl-2-(p-methoxyphenyl)pyrimidine-5-carbonitrile by refluxing in ethanol containing sodium hydroxide to give the corresponding sodium salt derivative which in turn was acidified to give 5-cyano-4-methyl-2-(p-methoxyphenyl)pyrimidin-6(H)one. Chlorination of the 5-Cyano-4-methyl-2-(р-methoxyphenyl)pyrimidin-6(1H)-one afforded 6-Chloro-4-methyl-2-(p-methoxyphenyl)pyrimidin-5-carbonitrile, which reacted with ethyl glycinate hydrochloride to give Ethyl (5-cyano-4-methyl-2-(p-methoxyphenyl)yrimidin-6-yloxy)acetate, which underwent cyclization to give the ethyl 5-amino-4-methyl-2-(p-methoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylate. The reaction of 5-Cyano-6-chloro-4-methyl-2-(р-methoxyphenyl)pyrimidine with piperidine, and morpholine, gave the 4-Methyl-6-(morpholin-4-yl)-2-(р-methoxyphenyl)pyrimidine-carbonitrile and 4-Methyl-6-(morpholin-4-yl)-2-(р-methoxyphenyl)pyrimidine-5-carbonitrile respectively . The Ethyl 5-amino-4-methyl-2-(р-methoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylate was used as key intermediates in the synthesis of other pyrrolo[2,3-d]pyrimidine derivatives, pyrimido[4\,5\:4,5]pyrrolo[2,3-d]pyrimidines and triazolopyrro lopyrimidines by reaction with different reagents . Seven compounds were selected and screened in vitro for their antimicrobial activity against four strains of bacteria and two fungal species .
Antibiotic Susceptibility and Concentration of Airborne Coagulase Negative Staphylococci (CoNS) in the Intensive Care Units (ICU) of Different Hospitals in Northern Jordan
(Sebha University, 2013) ZIAD ELNASSER, ISMAIL SAADOUN, IBRAHIM ALI AL TAYYAR
Coagulase negative staphylococci (CoNS) constitute an increasing nosocomial problem especially in hospitals due to intrinsic and acquired resistance to antimicrobials agent. Our objective is to evaluate the CoNS in the adult intensive care units (ICU) and nursery intensive care units (NICU) of Northern Jordan Hospital, to different antibiotics. 128 air samples of 100 liters volume/min were collected by a microbiological air sampler from the above units during the period June to December, 2005. Air samples were impacted on Trypticase soy agar (TSA), and then incubated at 37 °C for 48 h. Each bacterial colony appeared on agar plates were sub-cultured on TSA or blood agar and incubated at 37 °C for 24-48 h, and then identified by standard methods. The average bacterial count in the ICU and NICU was 311.7 and 322 cfu/m3, respectively. CoNS were the most prevalent bacteria of all Gram positives in ICU (26.5%) and NICU (23.5%) with S. saprophyticus been the most isolated species (> 65%). CoNS were the most commonly isolated Gram positive cocci in ICU and showed remarkable resistance to Novobiocin (66.9 %), but high susceptibility (> 90%) to Ciprofloxacin.
