Khalid H. Sultan,Saeb Y. Abdul- Rahman
International Journal of Poultry Science , 2011,
Abstract: The study was conducted to evaluate the effect of probiotic diet supplementation on some physiological parameters in Broiler Breeders. 30 Cobb Breeder hens were used (46 week aged), divided into 3 groups (10 hens each). The 1st group was reared on standard ration (control), the 2nd and the 3rd groups were given 10 and 20 gm of probiotic/kg ration for 4 weeks. The results revealed that the probiotic treatment causes a significant increase in LH and FSH serum levels (3rd group) and in T3 levels in (2nd and 3rd group) as compared with control group at p<0.05. Also the probiotic treatment causes a significant decrease in serum triglyceride levels and a significant increase in serum Uric acid level as compared with control. The above effects reflected in improvement of the egg weight, yolk weight and egg production % as compared with control. In conclusion, the probiotic supplementation of Broiler Breeders diet will improve the hormonal status and enhance the productivity.

International Journal of Engineering Science and Technology , 2010,
Abstract: Social networks tools are used as a means of building links to business websites where an online social networking has been harnessed as an invaluable asset for many corporate businesses. Due to the widespread personal use of social networks today is forcing organizations to leaders to effectively connect with employees and customers, and sometimes to keep an eye on the competition. In this paper we conducted on how the corporate companies are recognizing that there is an opportunity to use internal social networks to attract and retain talented staff, tap the most relevant expertise, enhance collaboration, and ultimately improve organizational performance and business outcomes. It is also analyzes how web-based networking platforms like Facebook, Twitter, Flickr, Myspace, Youtube and Linkedin allow the personal business network online and gives access to people, jobs and opportunities like never before. As such, corporate businesses can now make best use to these social network tools by exploiting the vast amount of personal information it holds on their market research databases.

Abstract: Aim: To compare between classic open surgeries and minimally invasive surgeries in Lumbar Spinal Stenosis. Methods: A comparative descriptive study, involved 117 patients suffering from lumbar canal stenosis, aged between 40 - 70 years; admitted to department of Neurosurgery from March 2011 till august 2016 in King Fahad Hospital in Saudi Arabia. Study groups are consisted of group A as patients managed with classical laminectomy, group B as patients managed with endoscopic spinal procedures and group C as patients managed with microscopic decompression facilitated by the Metrex Tubular System. SPSS was used in data entry and analysis, and ethical considerations taken into consideration and participants filled the required inform consents. Results: Age of particaoncet ranged from 45 - 63 years, Mean +/ 50. The degenerative canal stenosis with acute disc single level (cauda equina syndrome) was the most common type of lumbar canal stenosis encountered in group A; the unilateral foraminal and lateral recess stenosis without disc prolapse was the most common type of lumbar canal stenosis encountered in group B; while the unilateral foraminal and lateral recess stenosis without disc prolapse was the most common type of lumbar canal stenosis encountered in group C. Classic laminectomy and disectomy used mostly in group A; endoscopic unilateral decompression lamino-foraminotomy without discectomy used mostly in group B and bilateral microscopic laminectomy without discectomy followed by unilateral microscopic laminoforaminotomy without discectomy used mostly in group C. Mean of operation duration was the highest in both gender of group A, followed by group B, then group C. Unintended durotomy was the most common intra operative complications occurred in the whole study especially in group A. Mean of blood lost was the highest in both gender of group A, followed by group B, then group C. Postop complications in the patients of study groups were the highest in group A (33.3%), followed by group B (8.5%) and then group C (2%). Conclusion: Microscopic decompression facilitated by the Metrex Tubular System is the most effective technique of Surgery for Lumbar Spinal Stenosis and the least intra-operative and post-operative complications.

Uznir Ujang, Alias Abdul Rahman
Journal of Geographic Information System (JGIS) , 2013, DOI: 10.4236/jgis.2013.53030

While the use of three-dimensional (3D) geographical information system (GIS) is becoming in rapid development and being used in various fields such as urban and regional planning, disaster management and planning, mobile navigation and etc., commercial and open source GIS software packages tend to offer 3D-GIS functionalities for their products. On the basis, GIS analysis functions are to provide information with respect to geographical location and by having 3D spatial data as an input, it will give advantages in providing horizontal position information. However, to analyze moving objects (temporal) in 3D seems not an easy task and not fully supported by current GIS platform packages. Previously in two-dimensional (2D) GIS practice, main issue addressed by researchers in managing temporal spatial objects is GIS packages were designed based on hardware and software constraints whereby it should be based on the temporal spatial objects ontology. Nowadays, the trend of managing temporal 3D data is via 3D spatial simulation or animation. This approach will not in assistance for GIS users in conducting spatial queries. Without having a suitable ontology and valid topological data structure for temporal 3D data, it will cause repetitive of temporal data (redundancy) and complications in executing spatial analysis in 3D environment. Therefore this paper focuses on the ontology for managing moving 3D spatial objects (i.e. air pollution, flood). The characteristics of moving objects were reviewed thoroughly by categorizing it based on its different appearances. Moreover, existing methods in managing temporal database were addressed and discussed for its practicalities. Another important aspect in managing temporal 3D objects is the implementation of topological data structures for 3D spatial objects were reviewed. In the last section of this paper it summarized the issues and further ideas towards implementing and managing temporal 3D spatial objects in GIS based on the Geoinformation Ontology (GeO).

Abdul Rahman
Mathematics , 2007,
Abstract: We present the construction and properties of a self-dual perverse sheaf S_0 whose cohomology fulfills some of the requirements of String theory as outlined by T. Hubsch in hep-th/9612075. The construction of this S_0 utilizes techniques that follow from MacPherson-Vilonen (Inv. Math. vol. 84, pp. 403-435, 1986). Finally, we will discuss its properties as they relate to String theory.

Abstract: This study was carried out to investigate the Vitamin C protective effect against the H2O2 – induced oxidative stress effects on some hematological and biochemical parameters of female quails (Coturnix coturnix).120 sexed female quails were reared from 21-56 days. Randomly the birds divided into 4 groups (30 birds/group) (2 replicates) as follows: 1st group: T1 (control): reared on standard ration and tap water.2nd group: T2 (H2O2 group): reared on standard ration and tap water supplemented with 0.5% H2O2. 3rdgroup: T3 (Vitamin C group): reared on standard ration supplemented with 300mg/kg ration and tap water. 4thgroup: T4 (H2O2 + Vitamin C): reared on standard ration supplemented with 300mg/kg ration and tap water supplemented with 0.5% H2O2. Results revealed that Vit. C supplementation improve female quails blood picture, this effects were adversive to the H2O2 effects, Vit. C causes a significant increase in lymphocytes % and a significant decrease in hetrophils and hetrophils: lymphocyte ratio (stress index), also a significant decrease in glucose, cholesterol and triglycerides, as well as a significant increase in serum protein when compared with the effect of H2O2 – induced oxidative stress. In conclusion, oxidative stress causes a negative effects on blood picture and some serum biochemical parameters, and Vit. C supplementation reduces and reverses the H2O2 effects.

Abstract: The study was carried out to investigate the effect of employing sesame seeds in broiler breeder diet on some physiological parameters. 30 Cobb breeder hens (36 week age) were divided into 3 groups (10 hens each). The 1st group was reared on standard ration (control), the 2nd group was reared on standard ration and given orally Sesame seeds capsules daily (250 mg /kg) and the 3rd group was reared on standard ration and given orally Sesame seeds capsules daily (500 mg/kg). The treatment continues for 4 weeks period. Results showed a significant increase in the RBCs, Hb and PCV in the 2nd and 3rd group compared with the control group. This was accompanied by a significant decrease in MCV and MCH. Significant increase in the MCHC in the 3rd group compared with other groups after 2 and 4 weeks of treatment was noticed. Sesame seeds treatments for 4 weeks also caused a significant increase in the WBC count in the 2nd and 3rd group as compared with control. Hormonal Assay revealed that sesame seeds treatment with tow doses has no effects on plasma levels of LH hormone (4.94 and 4.48 miu/ml) compared with control (3.93 miu / ml), but the sesame seeds treatment (500 mg/kg) causes a significant increase in plasma levels of FSH (0.88 miu / ml) compared with the control (0.64 miu/ ml). Sesame seeds treatment, also, increased the egg weight, shell weight and yolk weight and it reached the levels of significantly in the 3rd group (66.15, 7.33 and 20.65 g) respectively as compared with control (61.48, 6.86 and 18.66 g), respectively. It is concluded that, sesame seeds treatment enhanced erythropoiesis, FSH activity and some productive parameters.

International Journal of Research in Pharmaceutical Sciences , 2010,
Abstract: To improve the efficacy of amantadine (AMD) in chronic hepatitis C therapy, various prodrugs were designed and synthesized to enhance its hepatic delivery based on the incorporation of AMD into modified bile acid or cysteine derivatives. A new sensitive and selective HPLC method with fluorescence detection has been developed and validated for determination of AMD in human plasma for evaluation of the pharmacokinetics of these prodrugs. Betaxolol hydrochloride (BTX) was used as internal standard. AMD and BTX were isolated from plasma by protein precipitation with acetonitrile and derivatized by heating with 1,2-naphthoquinone-4-sulphonate (NQS) in alkaline medium (0.01 M NaOH) at 90±5 °C for 45 min. Separations were performed in isocratic mode on Nucleosil CN column (250 mm length × 3.9 mm i.d., 5 μm particle diameter) using a mobile phase consisting of acetonitrile:10 mM sodium acetate buffer (pH 3.5):methanol (20:70:10, v/v) at a flow rate of 1.5 mL min 1. The derivatized samples were extracted with chloroform and reduced with 0.03% potassium borohydride. The reduced fluorescent AMD-NQS derivative was monitored at emission wavelength of 382 nm after excitation at 293 nm. Under the optimum chromatographic conditions, a linear relationship with good correlation coefficient (r = 0.9989, n = 5) was found between the peak area ratio of AMD to BTX and AMD concentration in the range of 30–3200 ng mL 1. The limit of detection and limit of quantification were 6.7 and 21 ng mL 1, respectively. The intra and inter-assay precisions were satisfactory; the relative standard deviations did not exceed 1.57%. The accuracy of the method was proved; the recovery of AMD from spiked human plasma were 97.51 100.95 ± 0.26 1.57%. The method had higher throughput as it involved simple sample preparation procedure and short run-time (<15 min). The results demonstrated that the proposed method would have a great value in the pharmacokinetic studies for AMD released from the synthesized produgs.
