    Twelve clay samples were taken from three pits below the basaltic loose veneer rubble down to the basaltic bedrock in order to discuss the origin of the clay minerals in relation to the origin of the soil. The non-clay minerals present are: quartz, calcite and feldspar which are abundant in all soil samples. The basaltic bedrock as well as the loose fragments are made up of fresh basalt. There is a sharp contact between both the basalt fragments and the soil. The clay minerals are: palygorskite, kaolinite and a mixed-layer of illite/smectite. These were observed in the distribution of the clay minerals, and no transitional phases were observed along the pits. The clay minerals were formed by the effect of wind-blowing /detrital and transported. Consequently, soil accumulation north of Azraq Al-Druze seems to be wind blown and not due to basalt alterations

    The volcanism in the western Arabian plate extends from the Red Sea through the Harrat Ash-shaam system to western Syria. The aforementioned volcanic activity produced large quantities of alkali olivine basalts and tuffaceous materials. The stratovolcano (7km) NE of Dair El-Kahif, NE Jordan has been investigated. The results show that dominant mineral phases are olivine, augite, plagioclase, magnetite and ilmenite. Chemical analysis of the whole rock tuff samples confirms alkali olivine magma origin. Low concentrations of Li and Rb in tuff samples are used as an argument against the contamination of the basaltic magma during its journey to the surface. The MgO and Mg-values (Mg/Mg+Fe²+) in samples from volcanic tuff exhibit different degrees of fractionation, which are indicated by the varying concentrations of incompatible trace elements (Ba, Rb, Sr). The thermometric evaluation of tuff determined by using pyroxene thermometers revealed a temperature range between 1022-1083°C and a pressure of 5-10 kbars. The low Mg-ratio (Mg/Mg+Fe²+) is due to fractional crystallization of olivine and pyroxene in tuff samples. The variations of incompatible elements imply derivation from a peridotite source in the upper mantle with low degree of melting (<20%). The volcanic activity took place in phases corresponding to rifting associated with the sinistral movement along the Dead Sea Transform and the later reactivation processes

    This paper examines the role of law by enforcement agents, especially the police, in investigating the crime of terrorism in Jordan, and focuses on the procedural rules for the investigation of terrorism, the nature of the police agencies in the Jordanian criminal justice system, the main traditional and specified, investigatory and accusatory authority of police agents and the basic right of protection of the accused against actions taken by government agencies, at the preliminary investigation stage. In this article, the authors have adopted the qualitative research methodology. The paper concludes that in order to provide more realistic protection to the accused during investigation, the law should be reviewed

    Forecasting breakage rate in water distribution networks using evolutionary polynomial regression

    The economic, social and environmental impact of water main failures impose great pressure on utility managers and municipalities to develop reliable rehabilitation/replacement plans. The annual number of breaks or breakage rate of each pipe segment is known as one of the most important criteria in condition assessment of these pipelines. A model is developed in this research to predict the annual number of breaks in water pipes. The developed model utilizes Evolutionary Polynomial Regression (EPR), which is intuitive data mining technique. The model is applied to a case study to test its effectiveness. The case considers the water distribution networks of in the cities of Doha in Qatar; Montréal, Moncton and Hamilton in Canada. The results indicated that the developed models successfully estimated the breakage rate for the city of Montréal and the number of breaks for the city of Doha with a maximum coefficient of determination of 88.51% and 96.27% respectively. This demonstrates the accuracy and robustness of the developed models in forecasting the number of breaks and breakage rate in water distribution networks.Non UBCUnreviewedFacultyOthe
