Determination of Water Demand Management in GCC Using GIS

Arab GCC((Gulf Corporation Councel) is facing potential water shortages. The alarming increase in the scarcity of water in various parts of the world. Water is a main issue in many countries especially in those GCC, it has focused a global attention on the need for a stronger and more appropriate water resource management and availability solutions. imperative for nations to come up with more focused and direct measures that would address and stem this resource scarcity. Water sustainability needs a balance between demand and availability. The main objective of this paper is the application of these concepts to Arabs countries. Water demand management is about achieving a reduction in the use of water resources, normally through increased efficiency of water application. The management of water resources was not explicitly included in the past from thirty-five years in all most of those countries normative system partly because water was believed to be a free good in mind, and was not accepted to have a price to pay to use it. The main goal of this paper is showing, how Geographical Information Systems (GIS ) using ESRI (Environmental System Research Institute)  or ArcGIS 10.2 product , can be used to support infrastructure planners and analyst on water demand of a local area in GCC (Gulf Corporation Councel ) they are (Saudi Arabia ,Kuwait, Bahrain, Oman  and UAE).

A study of visible light communication channels for high speed roadways

A visible light communication channel study is conducted for high speed roadways under clear night sky conditions in which street light poles transmit to receivers on top of moving vehicles. A detailed analysis of the communication channel is undertaken. Exact and approximate analytical DC channel responses are obtained and analyzed, and the channel capacity and RMS time delay spreads are derived. Numerical studies verify that visible light communications are feasible for high speed roadways

Design and implementation of a secured SDN system based on hybrid encrypted algorithms

Software defined network suggests centralizing network knowledge in one network portion by separating the routing (control plane) mechanism from the transmission network packet operation (data plane). The control plane is composed of one, two or more controllers which are considered as software-defined networking (SDN) network brain where the real intelligence is incorporated. The process of separating the control unit from the data unit led to a problem related to poor security of data sent in the network, so solutions to these problems had to be found. In this paper, address this problem by implementing robust algorithms to encrypt information, based on advanced encryption standard (AES), Rivest–Shamir–Adleman (RSA), and hybrid encryption algorithms to guarantee data protection and authenticity. The results showed that the hybrid coding method is better in terms of security and improved time (faster than RSA alone) by applying several scenarios in the SDN network to a set of encrypted files

Finally; in this work, three sets of GIS models have been produced. These are catchment area; patient profile and patient distribution; and patient flow models. The results of GIS provided by the combined different entities based on their common geographic occurrence makes it a very valuable tool in epidemiological research, disease surveillance and monitoring. Some recent applications of GIS include vector borne diseases, water borne diseases, environmental health and modeling exposure to electromagnetic fields. Also, our results suggest that GIS is highly relevant to meet the demands of outbreak investigation and response, where prompt location of cases, rapid communication of information, and quick mapping of the epidemic’s dynamics are vital. In this work the former is used to produce drive-time hospital service area and the route is applied at the selected hospital to calculate the size of its served demand. It is recommended that more studies should be done in this work; three sets of GIS models have been produced. These are catchment area patient profile and patient distribution and patient flow models. So, we think that such output of creating and implementing a GIS models are produced to help a local health planners in their health care decision making output. Keywords: GIS; Health planners; network analysis; hospital served demand; spatial data

Experimental and Numerical Study of Precast Concrete Pipe with Single Elliptical Steel Cage Reinforcement

Reinforced concrete pipe (RCP) with single elliptical (SE) reinforcement offers cost savings and is permitted by Canadian and American standards. Yet, its use has not yet gained momentum primarily due to limited knowledge of its structural performance. This study explores the structural behaviour of full-scale 1050 mm and 1200 mm diameter RCP reinforced with SE cold drawn steel wire cage under the Three-Edge Bearing Test. Results indicate that RCP with SE reinforcement designed per current standards did not meet the specified 0.3-mm crack and ultimate load capacity. Hence, pertinent provisions in CSA A257.2 and ASTM C76 for RCP need to be updated with specific and more suitable guidance for SE cage RCP. The study also investigates the effect of the SE cage rotation on the structural capacity of the pipe through finite element modelling. The model indicates a significant reduction in ultimate load capacity from the cage rotation

Multiplex polymerase chain reaction identification of Candida species colonized sputum of patients suffering from various respiratory tract disorders in Duhok, Iraq

Background: Candida species are part of the body normal flora. Under certain conditions, these opportunistic microorganisms may lead to infection. The purpose of this study was to identify Candida species isolated from sputum from patients suffering from respiratory tract disorders.Methods: A total of 59 sputum samples taken from patients attending Azadi hospital at Duhok province, Kurdistan Region/Iraq. For primary isolation, sputum samples were cultured on sabouraud dextrose agar (SDA). Suspected colonies of Candida isolates were then sub cultured on chromogenic Candida agar for presumptive identification. Genomic DNA extraction was performed using a genomic DNA extraction kit. For rapid identification of Candida spp, specific primers based on the genomic sequence of DNA topoisomerase 11 of C. albicans, C. parapsilosis I, C. parapsilosis II, C. guilliermondi, C. dubliniensis, C. krusei, C. kefyr and C. glabrata, C. tropicalis I, C. tropicalis II, C. lusitaniae were used. The Multiplex PCR products were separated by electrophoresis in 1.5% agarose gel, visualized by staining with ethidium bromide, and photographed.Results: Three Candida species namely C. albicans, C. glabrata and C. tropicalis were differentiated by their colour produced on Chromogenic Candida agar. PCR with the primer mixes yielded 4 different sized of PCR products corresponding to C. albicans, C. glabrata, C. Keyfer and C. tropicalis II, C. glabrata was the most common species (33.33%), followed by C. albicans (16.66%). The highest rate of isolation of Candida species was between the ages of 36 to 45.Conclusion: This study concluded that phenotypic characteristics on selective agar medium such as chromogenic Candida agar are useful for presumptive identification of Candiada spp with the support of molecular method such as multiplex PCR.

Isolation of Entomopathogenic and Opportunistic Fungi from Soil in Duhok Province,Kurdistan Region of Iraq by Different Selective Isolation Media

Soil is a natural habitat for several important insect pathogenic fungi which play a key role in regulating populations of soil dwelling insect pests. Forty soil samples were collected during 2012-2013 from different agro ecosystems at Duhok governorate were screened for the presence of soil dwelling entomopathogenic fungi using four different selective isolation media. The four isolation media were prepared by modifying previously prepared DOC2 medium and a selective medium based on the use of Cetyletrimethyl ammonium bromide (CTAB) with oatmeal agar (OT) as a basal medium. The percentage occurrence of fungi and number of detected species was significantly affected by the type of isolation medium. The least number of recovered species (5 species) was on DOC2 medium, whereas, the highest number (14 species) was displayed by CTAB+OT medium. The two true entomopathogenic species Lecanicillium lecanii and Metarhizium anisopliae were successfully recovered only with our new formula by combination of DOC2+CTAB and OT+CTAB media, whereas, DOC2 and DOC2+OT media failed to recover the two species. This result indicated that addition of CTAB to media was a vital factor for the recovery of the two entomopathogenic species. L. lecanii and M. anisopliae have been recorded for the first time from Iraqi soil. Several other opportunistic pathogens were also detected. These include Aspergillus flavus, A.parasiticus, Clonostachys rosea and Fusarium species. The distribution of entomopathogenic and opportunistic fungi is discussed in relation to different agroecosystems and to some physical and chemical characteristics of soil samples. Key words: Entomopathogenic fungi, soil, Iraq.
