    There is not much research written about the relationship between education and the rise of terrorism. Some scholars have urged for educative response to end terrorism (Krueger and Maleckova, 2003; Brockhoff et al., 2015; Malazada, 2016; Illiteracy rates drop in Iraq: Government, 2014) In his study, Brockhoff et al., (2015) found that when country specific factors like the economic situation and political representation were unfavorable, education is the reason some individuals become terrorists. Abrifor (2008) concluded that abuse of students in Nigeria lead them to get involved in criminal activities, suicide bombing and terrorism. In light of these studies, it is legitimate to think that the problems facing the Iraqi educational system and the low quality of education are the main causes that fuel terrorism. Every Iraqi citizen knows that education in Iraq is deteriorating. However, the governments of Iraq have not tried to improve the educational system to make it resistant to terrorism. This study tries to find out if the Iraqi citizens who studied their whole life in the Iraqi educational system and who have suffered or know someone who have suffered from terrorism think that education in Iraq is responsible for the spread of terrorism in the country. The study also aims to find out if the respondents think that improving the educational system in Iraq can potentially exterminate terrorism from the country. Additionally, the study tries to find out the main issues that Iraqi education policymakers need to address so that education can be used as counterterrorism. For the study, a survey was used as the main method of data collection. The survey was posted on Facebook groups and 666 respondents answered it. The study found that most of respondents think that there is a relationship between education and terrorism in Iraq. The study also found that most of respondents think that improving the Iraqi educational system can exterminate terrorism in Iraq. In addition to that, the study found that the majority of respondents think that Iraqi educational system must be improved and unified to introduce students to different point of views, religions, and cultures, be inclusive and secular to promote pluralism in the country, and stop using or teaching about violence in schools. Furthermore, respondents favored that the goals of education must be given importance not the curriculum itself and that critical thinking is taught to help students be able to think objectively before adopting certain ideology. An important issue that the study found is that the majority of respondents think that history and Islamic education must be modified and their books must be rewritten to include other religions and ethnic groups in the country. This study suggests that the educational system in Iraq must be improved as soon as possible to tackle the issue of terrorism. The Iraqi educational system must be modified to be secular and inclusive. Islamic Education must be changed into either “Citizenship Education or Teaching about Religions” that many countries around the world have adopted. Therefore, it is important that teaching religion becomes non-denominational so that all students can feel welcomed and equal in the classroom

    This thesis investigates the design, performance and control of a synchronous reluctance machine (Synchrel) drive. The Synchrel machine is proposed for variable speed drives because of its advantages over other machines. The rotor has no cage winding, brushes or slip rings. The torque ripple levels are lower in the Synchrel machine than the switched reluctance machine as it operates from a standard sine wave supply. An axially laminated rotor was designed based on finite element analysis, with the aim of producing the same output power as obtained from an induction motor (M) with a similar stator. Using vector control, the developed torque is controlled by regulating the stator current vector. Two vector control schemes are used, maximum torque per ampere and constant current in the direct axis. The output torque characteristics of the machine have been confirmed by finite element analysis. Slotine's approach of sliding mode control is used for position control of the vector controlled synchronous reluctance machine. A comparison is undertaken between the performance of a fixed gain controller with two sliding mode controllers, for both the regulator and servo cases. Invariant performance is obtained using Slotine's sliding mode control approach, unlike with a fixed gain controller. Robustness to parameter variation is an important feature of this technique. This robustness can be achieved through the control law design, assuming parameter variation bounds are known. These improvements are demonstrated for variations in load inertia. Inductance ripple affects machine performance, for example decreasing output torque and increasing core losses. A state space model for the machine that incorporates this inductance effect, yields drive simulation results that agree with experimental results

    Antineuronal antibodies in autistic children: relation to blood mercury

    Get PDF
    Background: It was recently suggested that autism, a severe neurodevelopmental disorder, may involve an autoimmune pathogenesis. Mercury (Hg) is a potential risk factor for autoimmunity in autistic children. Objective: We sought to investigate the expression of antineuronal antibodies, as an index of autoimmunity to brain, in autistic children. The potential relationship between blood mercury and these antibodies was also investigated. Methods: Forty autistic children (20 with mild to moderate and 20 with severe disease) were studied in comparison to 40 healthy children. After complete clinical and neuropsychiatric evaluation, serum antineuronal antibodies and blood Hg levels were estimated. Results: Autistic children had significantly higher seropositivity for antineuronal antibodies (67.5%) than healthy controls (5%). Similarly, the former group had significantly higher blood Hg levels than the latter (p < 0.0001). In addition, the two markers were positively associated with some parameters such as the family history of autoimmunity, autistic severity and some important clinical manifestations of autism (mental retardation, behavioral abnormalities and autistic regression) as well as EEG abnormalities. Conclusion: Autism may be, in part, one of the pediatric autoimmune neuropsychiatric disorders. Such autoimmunity may be triggered by environmental Hg exposure. Further studies are warranted to enforce these concepts. If these assumptions could be proved, routine assessment of serum antineuronal antibodies and blood mercury in autistic children would be mandatory. Studies assessing the role of immunotherapy and Hg chelators as new therapeutic modalities for autism are also recommended.Keywords: Antineuronal antibodies; autism; autoimmunity; children; heavy metals; EEG; mercuryEgypt J Pediatr Allergy Immunol 2007; 5(1): 21-3

    This study aims at highlighting the most contributing and influential factors to accident occurrence at hazardous locations of local urban roads, and correlating accident characteristics to different factors including geometric elements, traffic speed, pavement type, lighting conditions, type of collisions, pedestrian facilities existence and traffic conditions. The study was conducted using twenty-eight hazardous locations at Amman-Jordan roads. Each of the hazardous locations had at least twenty accidents and two fatality records per year. Data were collected through different sources that included Great Amman Municipality, Traffic Institute, Police Traffic Department and field studies. Different stepwise statistical regression models were developed to correlate accident characteristics with the studied variables. It was found that the logarithmic and linear models were the most significant and realistic models that can be used to predict the relationship between the accident characteristics as a dependent variable and the other studied variables as independent variables. The developed models were strong and predictable because the coefficient of multiple determinations was very close to the adjusted coefficient of multiple determinations. The following variables were found to be the most significant contributors to traffic accidents at hazardous locations: average running speed, posted speed, maximum and average degree of horizontal curves, number of vertical curves, median width, type of road surface, lighting (day or night), number of vehicles per hour, number of pedestrian crossing facilities and percentage of trucks. The study could open the door for planners and traffic engineers to overcome the problems associated with traffic accident occurrence at hazardous locations and enhance their safety. The developed models showed that accident characteristics such as number of accidents, number of fatalities, number of injuries, type of accident and number of vehicles involved in accidents, and statistics of hazardous locations could be predicted if the traffic conditions, geometric elements and environmental variables are known. The study could also be enhanced if incorporated with drivers’ characteristics including socio-economic data

    Objective: The aim of the present investigation was to study the potential effect of sweet orange juice against liver genotoxicity induced by lannate. Methods: adult 36 female rats were divided into 6 groups: group C (control group), group L (lannate group) injected intraperitoneal (i. p.) with 1 mg/kg b. wt. lannate for one day, group J (orange juice group) orally administered a dose of 0.1 ml/10 g b. wt. of orange juice for 48 h, group J+L received the orange juice prior to lannate, group J with L received lannate in continuous with the orange juice and group L+J received lannate prior to the orange juice. Tested parameters were DNA fragmentation, micronucleus, histopathology examination and biochemical analysis. Results: it was found that, the intake of lannate caused high DNA fragmentation and significant increase (P<0.001) in the number of micronucleated polychromatic erythrocytes in the bone marrow. Furthermore, lannate exhibited some pathological changes in the liver tissues as well as a significant (P<0.001) decrease in the total antioxidative capacity (TAC) and a significant increase in the total oxidative capacity (TOC). On the other hand, orange juice administration of all treatments (pre-treatment, continuous and post-treatment) gave some amelioration against liver damage induced by lannate. While the best results were evidenced in the continuous treatment group where the juice could attenuate liver DNA fragmentation and significantly decreased (P<0.001) the number of micronucleated polychromatic erythrocytes. In addition, it improved the induced degenerative histopathological changes as well as ameliorated the changes occurred in TAC and TOC significantly (P<0.001). Conclusion: the antigenotoxic impact of orange juice against lannate was therapeutic and hence can counteract the poisonous effect of the pesticide in people who exposed to it
