Evaluation of Pre-qualification Criteria: Client Perspective; Jordan Case Study
Sultan A. Tarawneh
Journal of Applied Sciences , 2004,
Abstract: The purpose of this work is to identify the perception of the major clients on the importance of the pre-qualification criteria used to qualify contractors in the Jordanian construction industry. Also, it is aimed to provide suggestions for contractors to increase their chances in being pre-qualified by major clients. To achieve the objective of this work, the findings of previous exploratory qualitative interviews with owners, directors and senior managers of major client organizations in Jordan have been examined. The findings of this work indicated that public and private clients have different views about the importance and priorities of the pre-qualification criteria. Public clients place more weight on price after the contractor has been qualified. Special pre-qualification criteria are highly needed in Jordanian construction industry to meet the new requirement such as good manufacturing practice.
Effect of Treated Waste Water on the Behavior of Unsaturated Soil
Omer N. Maaitah,Sultan A. Tarawneh
Journal of Applied Sciences , 2003,
Abstract: Many tests have been carried out on Karak clay to explore the unsaturated shear strength and volume change characteristics. The specimens have been prepared with and without treated contaminated water. A specific experimental programme has been planned and completed on a range of degree of saturation. The shear strength test and swelling test results with distilled water have been compared with the presence of contamination in Karak clay. The test results show that there is not too much difference between the unsaturated shear strength tests on specimens without and with contaminated water in Karak clay. Also, the use of treated water will not increase or decrease the swelling. The results obtained from this study are expected to be of benefit and practical use for carrying out stability analysis of structures like embankments and foundations supported by clay particularly in a country that suffers from water shortage like Jordan. However, experimental evidence to support this study is still limited.
A Suggested Theoretical Framework for Software Project Success  [PDF]
Hroon Tarawneh
Journal of Software Engineering and Applications (JSEA) , 2011, DOI: 10.4236/jsea.2011.411076
Abstract: Current literature on software project management indicates that the majority of software projects either are considered a failure or challenged. These projects are characterized by exceeding budget, exceeding time, and failing to meet customer expectations. The fact that most projects fail highlights the need for research regarding the factors that lead to software project success or failure. This paper presents a theoretical framework for software project success. Based on deep analysis of current literature on software success factors, a theoretical framework is formulating. The suggested framework shows factors that have to be carefully considered in order to achieve software project success. The factors included in the framework are dividing into four categories: organizational factors, technical factors, people factors, and culture factors. The suggested framework is new in the sense that it includes many factors that are not founding together in any of the previous similar frameworks.

Must go beyond human resources information system (HRIS) traditional role in the process of selection and appointment of the new human resource to work in the organization, which is merely providing information to decision makers about the people who stepped forward to fill a job order that differentiation among those application. That the ambitious goal of that system to provide a base for data (data bank) includes all of the details of the employment available in the market.
A Comprehensive Outlook of Mining Industry in Jordan, Opportunities and Threats  [PDF]
Khaled Al Tarawneh
Open Journal of Geology (OJG) , 2016, DOI: 10.4236/ojg.2016.69084
Abstract: Jordan’s mining sector is considered the cornerstone to the Jordanian economy. It plays a vital role in growth of many other important sectors in the economy and contributes to the Jordan’s standard of living. The mining industry in Jordan is dominated by the production of phosphate, potash, building and decoration stones, glass sand and other nonmetallic resources. Recently, Jordan has been ranked as the sixth largest producer and the second largest exporter of phosphate, the fourth largest producer and the second largest exporter of potash, and has the 5th largest oil-shale reserves in the world. Also, Jordan has sustainable amounts of uranium around 3% of the world resources. The main objective of this research is to focus on the present status of mining industry in Jordan with the aim to emphasis the most important industries, and its effect on the economy of Jordan in order to generate new wealth depends on its mineral endowment. A literature review has been carried out by reviewing the most published articles and the publicly available reports published by various Jordanian Institutions as well as from the private sector. The author reveals that there are many positive outlooks which are looming with an increasing domestic added value along with investing in other areas, such as feldspar, clays, travertine, gypsum, zirconium, uranium, copper and rare earth elements (REE). This requires activating the exploitation of many other untapped mineral resources in the country to achieve a progress that works for meeting the global great demands worldwide. In this context, successive governments have put effort into policies that promote and facilitate investment in the mining sector in Jordan. A comprehensive outlook of the mining sector in Jordan has been discussed in this article. The author also highlighted the opportunities and threats in this sector and more important dilemmas focused on what needs to be carried out by the Jordanian government, including important recommendations to encourage investment in this field and inspire

Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.58011
Abstract: This study aimed to know the friendship skills of students with Learning Disabilities (LD) from the perspective of their teachers, and it aimed to investigate the effect of some variables on these skills. In order to achieve the aims of this study, checklist of friendship skills for students with LD was used to collect data about 300 students with LD (150 boys and 150 girls). The results indicated that about 69.3% - 70.7% from teachers of students with LD indicated that the students with LD have few friends or no friends. Also it indicates that there are significant differences between students with LD in the friendship skills due to gender to favor boys. And there are no significant differences between students with LD in the friendship skills due to age and interaction between gender and age.
Reconnection of Vortex Bundles Lines with Sinusoidally  [PDF]

Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.46130
Abstract: Using the vortex filament model with the full Biot-Savart law, we show that non-straight bundles of quantized vortex lines in HeII are structurally robust and can reconnect with each other maintaining their identity. We discuss vortex stretching in superfluid turbulence in many cases. We show that, during the bundle reconnection process, Kelvin waves of large amplitude are generated, in agreement with previous work and with the finding that helicity is produced by nearly singular vortex interactions in classical Euler flows. The reconnection events lead to changes in velocities, radius, number of points and total length. The existence of reconnections was confirmed by other authors using the model of nonlinear Schr?dinger equation (NLSE). Our results are agreed with the finding of other authors and extension to our numerical experiments.
Fractional Yield, Extract Composition and Variability from Jordanian Oil Shales  [PDF]
Hani M. Alnawafleh, Feras Y. Fraige, Khalid E. Tarawneh, Ibrahim A. Sarairahc, Laila A. Al-Khatib
Journal of Analytical Sciences, Methods and Instrumentation (JASMI) , 2016, DOI: 10.4236/jasmi.2016.63007
Abstract: Surface and subsurface oil shale (OS) rocks in Jordan have potential economic value for the country and still unutilized. This research paper focuses on central and southern OS deposits in Jordan. Brief characterization of four OS deposits is presented. Size distribution test and elemental analysis were performed. Shale oil was extracted via three solvation methods: Soxhlet extraction, extraction via mixing and stirring, and lastly super-critical fluid extraction. Major shale oil fractions were obtained from extract fractionation on chromatographic column. The nuclear magnetic resonance spectroscopy technique was used to study qualitatively the fractional composition of OS extract. Results show that all studied OS deposits have quite similar trend in their particle size distribution and their elemental composition. These OS deposits are found to be varying in their solvation behavior, fractional yield, and shale oil composition. Highest yield is obtained from polar solvents. The OS extraction via solvation processes is promising under certain extraction conditions such as super-critical conditions. The solvation variability of Jordanian OS indicates that different extraction techniques suit different OS deposits. Such variability should be considered in any future extraction options.
Effect of Chromium Compounds on Incidence of Social Aggression and Fertility in Prepubertal Male Mice
H.H. Hussain,Merza H. Homady,Khaled A. Tarawneh
Pakistan Journal of Biological Sciences , 2000,
Abstract: The effects of ingestion of trivalent (chromium chloride) and hexavalent (potassium dichromate) chromium compounds were investigated on social aggression and fertility in male mice. Prepubertal male mice were exposed to these salts in drinking water at concentrations of 1000 and 5000 ppm for 90 days. The exposure of male mice to chromium chloride at 1000 or 5000 ppm significantly augmented social aggression. Fertility was significantly reduced in males exposed to the hexavalent chromium compound. The number of implantation sites and the number of viable fetuses in females impregnated by males exposed to this compound had, however, no effect on fertility. Body, testes, preputial gland and seminal vesicle weights were significantly suppressed in males exposed to the hexavalent compound but no such effects were evident in mice given the trivalent chromium compound. The results show that the ingestion of trivalent and hexavalent chromium compound by male mice in prepubertal life have very different effects on both social aggression and fertility. Only potassium dichromate produced a pattern of responses clearly indicative of suppressed gonadal function.
