SUCCESSFUL LONG TERM ERADICATION OF FACTOR VIII INHIBITOR IN PATIENTS WITH ACQUIRED HAEMOPHILIA A IN SAUDI ARABIA
Galila F Zaher,Soheir S Adam
Mediterranean Journal of Hematology and Infectious Diseases , 2012, DOI: 10.4084/mjhid.2012.
Abstract: Acquired haemophilia A is a serious and potentially fatal bleeding disorder. Diagnosis is difficult and maybe delayed due to its rarity. The high mortality rate and the complex nature of treatment necessitate patient management at a haemophilia centre, where the required expertise and resources are available. Prompt diagnosis is crucial and early initiation of therapy could be life saving. Management includes initial control of bleeding followed by an approach to eradicate the coagulation factor inhibitor. In this paper we describe our local experience with acquired haemophilia A, which resulted in the successful control of major bleeding at presentation and eradication of inhibitors.

Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.712178
Abstract: The purpose of this study is to identify: the fluctuations and the changes in the social work profession in Israel reflected in the perceptions of veteran social workers, the origins of the profession in Israel, and the changes in the role of the social worker from its inception in Israel until today. This study used a qualitative research method. Interviews were conducted by students studying for their master of social work degree in the school of social work and social welfare at the Hebrew University of Jerusalem in a course on the historical and philosophical origins of the social work. the findings highlight the differences in the veteran social workers’ perceptions of the definition, nature, and role of social work in the country that parallel major developments of the profession in the country from its first days until the present, as reflected in the different periods of growth, expansion and development of the state of Israel.
Pitfalls of artificial grouping and stratification of scientific journals based on their Impact Factor: a case study in Brazilian Zoology
Machado, Fábio A.;Zaher, Hussam;
Zoologia (Curitiba) , 2010, DOI: 10.1590/S1984-46702010000400002
Abstract: the present contribution explores the impact of the qualis metric system for academic evaluation implemented by capes (coordination for the development of personnel in higher education) upon brazilian zoological research. the qualis system is based on the grouping and ranking of scientific journals according to their impact factor (if). we examined two main points implied by this system, namely: 1) its reliability as a guideline for authors; 2) if zoology possesses the same publication profile as botany and oceanography, three fields of knowledge grouped by capes under the subarea "boz" for purposes of evaluation. additionally, we tested capes' recent suggestion that the area of ecology would represent a fourth field of research compatible with the former three. our results indicate that this system of classification is inappropriate as a guideline for publication improvement, with approximately one third of the journals changing their strata between years. we also demonstrate that the citation profile of zoology is distinct from those of botany and oceanography. finally, we show that ecology shows an if that is significantly different from those of botany, oceanography, and zoology, and that grouping these fields together would be particularly detrimental to zoology. we conclude that the use of only one parameter of analysis for the stratification of journals, i.e., the impact factor calculated for a comparatively small number of journals, fails to evaluate with accuracy the pattern of publication present in zoology, botany, and oceanography. while such simplified procedure might appeals to our sense of objectivity, it dismisses any real attempt to evaluate with clarity the merit embedded in at least three very distinct aspects of scientific practice, namely: productivity, quality, and specificity.

Galila A. Yacout
Pakistan Journal of Biological Sciences , 2001,
Abstract: The effect of pyrolidine (L) or its copper-complex on rabbit melanocytes tyrosinase were studied. The results revealed that (L) appeared to be a non competitive inhibitor of tyrosinase for about 30% , while ( C ) was an activator for about 4.6 fold. In addition, general effects of (L) or ( C ) on rabbit were studied via serum parameters. The obtained data afforded an additional biological effect of the tested compounds .
Spectrophotometric Determination of Fluoride in Groundwater Using Resorcin Blue Complexes  [PDF]
Zaher Barghouthi, Sameer Amereih
American Journal of Analytical Chemistry (AJAC) , 2012, DOI: 10.4236/ajac.2012.39085
Abstract: New simple and sensitive spectrophotometric determination of fluoride in drinking groundwater has been developed using aluminium-resorcin blue complex. The method is based on the reaction of fluoride with the coloured complex to produce colourless aluminium fluoride complex and releasing of the free ligand. The relationship of the reaction of flu-oride with the complex is sixth-order polynomial function. The reaction reaches equilibrium at fluoride concentration of 0.054 mM. The equilibrium constant (Keq) was calculated as 1.12 × 1014. Beer-Lambert law is obeyed in the range 0.0 - 0.024 mM of fluoride (0.0 - 1.0 mg·L-1). The molar absorptivity at 502 nm is 6.45 × 103 L·mol-1·cm-1. Fluoride concentration higher than 1.0 mg·L-1 can be measured after proper dilution. The sensitivity, detection limit, quantitation limit, and the percentage recovery of 0.75 mg·L-1 fluoride for the method were found to be 0.357 μg·ml-1., 0.07 mg·L-1, 0.2 mg·L-1, and 101.1 respectively.
Fuel Saving and Control for Hybrid Electric Powertrains  [PDF]
Mohamed Zaher, Sabri Cetinkunt
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.55035
Abstract:

This paper focuses on comparing the performance of the embedded control of a hybrid powertrain with the original and downsized engine. The main idea is to store the normally wasted mechanical regenerative energy in energy storage devices for later usage. The regenerative energy recovery opportunity exists in any condition where the speed of motion is in the opposite direction to the applied force or torque. A rule based optimal robust control algorithm is developed and is tuned for different work cycles. A comparison of the fuel savings using the hybrid system with the original and downsized engines is performed.

The Socio-Emotional Adjustment of Learning-Disabled Students Undergoing School Transitions  [PDF]
Zaher Accariya, Mahmood Khalil
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.71014
Abstract: This study examined learning-disabled (LD) students’ subjective interpretation of their socio-cultural reality during the transition periods into junior high school. LD students are liable to have emotional, psychological and social problems: they are prone to anxiety, depression, and behavioral disorders, as well as feelings of low self-esteem and social isolation. These may lead to genuine crisis during the already difficult transition from elementary school to junior high. Research in the form of in-depth interviews was conducted on a sample of 12 LD adolescent, junior-high students. The findings point to three main concerns of LD adolescents regarding their transition to junior-high: A sense of isolation, a lack of social and adaptation skills, and a poor relationship with teachers. The findings of this study may be useful for planning intervention and prevention programs that provide support and assistance for LD students’ adaptation. It is crucial to assist LD students to develop and cultivate social and educational skills during the transition period, thus allowing them to learn how to cope, not only during this crisis period, but with other life situations.
Identifying “Good” Teachers for Gifted Students  [PDF]
Mahmood Khalil, Zaher Accariya
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.73040
Abstract: The purpose of this study is to identify the unique features that gifted students perceive to be essential in their teachers. In this qualitative, one-year study, data and responses from 15 gifted students in a high school in an Arab village in northern Israel were gathered from interviews, students’ personal diaries, and “letters of recommendation” that they were asked to write. The findings revealed that gifted students defined a good teacher through three major categories: 1) qualities in teachers; 2) excellent teaching; and 3) the unique qualities of the individual student-teacher relationship. Teachers of gifted students should ideally have unique personal, intellectual, and didactic characteristics and a unique attitude that empowers their students to realize their potential. Students place more importance on the inherent personality of the teacher than on acquired teaching skills. The findings point to a need for assessment of teachers for both personality and professional qualifications before they are assigned to the gifted classroom, and for special courses to train teachers of gifted students.
The Relations between Management Style, Work Motivation and Feeling of Stress among the Arab School Community  [PDF]
Zaher Accariya, Mahmood Khalil
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.714201
Abstract: The current research is based on the examination of the relationship between the level of the teacher’s motivation, and between the leadership of the manager and the educational climate, and because of the scientific importance attributed to the term of motivation and its impact on the quality of the work. In the current research, we examine a part of the factors that could affect the level of the teacher’s motivation. Therefore, the goal of this research is to enrich the existing knowledge in the field of motivating teachers by proposing and testing a theoretical model, in order to explain the difference in the motivations through interaction between personal variables for leadership of the manager and the environment (school climate), and the research group that has been tested, and consists of Arab teachers in Israel. The question that led to this study is: to what extent the level of motivation can be explained through leadership, school climate and work stress? The main hypothesis of this study is a positive relationship between the level of the teacher’s motivation, the manager leadership, and the school climate. In addition this research claims that work stress is the mediator variable which supports the previous relationship. The research was conducted in the framework of a survey, which included 200 teachers of teachers among Arabs in Israel, so that the method of selection of the participants in the survey was random. The main conclusion of this study is that the most influential factor on the motivation of teachers is the principal’s leadership. Apparently, the great majority of the population of teachers in the Arab sector in Israel is influenced primarily by their direct manager, rather than from the work environment. In other words, Israeli Arab teachers prefer to receive positive feedback and strengthening through the continuance of their work, from their immediate manager, and they don’t necessarily rely and get stronger from a cooperative atmosphere.
Differential Sensitivity of Male and Female Neuronal cells May Play a Role in Onset of Neuronal Diseases

Iranian Journal of Public Health , 2005,
Abstract: Due to the worldwide increase in the number of older people in both developed and developing countries, there is a public health concern for dealing with age related diseases such as neurodegenerative diseases. There is little known about the difference in neuronal cell responses between genders. Our understanding of the neuronal cell response regarding genders, will be useful for developing more efficient therapies for these diseases such as Alzheimer’s disease. To investigate gender differences in neuronal cell response against cell death inducers, we examined the percentage of cell death in male and female mouse primary cortical neuronal cultures. Our findings indicate that there is a difference in cellular response to ethanol (a cell death inducer) that may be the basis of how they behave in vivo of what may be seen in adults, as they age. These observation support this idea that genetic factors, most likely governed by X or Y chromosomes.
