Abstract | |
This subject deals with the land ownership of Sultan Abdul-Hamid II in Palestine during the period from 1876 to 1937. These lands have been known by various titles including the lands of Jeftlek, the Sultanate, and the Hamidian. The areas of these lands which equal about 2.5 million dunums broke the record of all the ownership that Palestine has witnessed in the modern age. The subject has been approached in three main axes. The first dealt with the factors that influenced the ownership formation specifically the enforcement system that was put in effect due to the economical, social and political conditions of Palestine. The other factor was the development policy adopted by the Ottoman Empire during the age of organization and the resistance of the foreign interpenetration movement. The second axis dealt with the size of ownership and the extent of its spread in the three Palestinian districts: Acre, Nablus, and Jerusalem. It focused in Al-Hawla basin, the sources of the Jordan River, the plain of Bisan valley, al-Fara’ valley, the plain of Jericho, the hill of Irad, the side of Zerqa River, Rafah, and other locations. The third axis was dedicated to deal with the radical changes that overwhelmed the Jeftlek lands. It also concentrated on the process of solving the question of ownership and returning them to the state treasury. In addition it dealt with the attempts of the foreign interpenetration movement specifically the Zionist corporations after the expulsion of the Sultan by the Union and Development Society in 1909 until it was settled during the British Mandate in 1937. | |

Abstract |
The purpose of this study was first, to find out the psychological tension and stress of the Israeli aggression on the faculty members through Al-Aqsa Intifada. Second, to findout the effect of demographic variables of: (sex, number of children, place of living, being humilated or beaten, living close or far from Israeli hot points, college, sallary, experience, social status, and professional rank) on faculty members psychological stress and tension. The study was conducted on (225) faculty members which represents a random sample of (61.8%) of the target population. A scale of psychological stress was constructed and validated by the researcher and applied to the sample. The results indicate that: 1. The psychological stress and tension on faculty members due to Israeli aggression over all mean was (58.7%) which considerd, in terms of psychological effect, high. 2. There were significant mean defferences among the three subscales of tension and stress. The highest score was on the social domain subscale with (60.4%), the second score of the academic domain subscale was (59%), and the third score of the psycholgocal domain was (3.2%). This could mean that the university faculty members were concerned with their students, and what is happeing on their society more than themselves. 3. There were significant mean differences (0.05) between level of tension and stress among faculty members with respect to demographic variables of: (place of living, being humilated or beaten by Israeli soldiers or not, college, and sallary). 4. There were no significant mean differences (0.05) between level of tension and stress among faculty members according to demographic variables of: (sex, number of children, living close or far from Israeli hot points, experience, social status, and professional rank. |

Abstract | |
This study aimed at investigating the attitudes of teachers and supervisors towards the use of student guidebooks by students, and investigating any significant differences between teachers’ and supervisors’ perceptions with regard to job, specialization, sex, and site of the directorate they work at। The population of the study consisted of teachers of the academic twelfth grade and all supervisors of all subject matters at the West Bank. All supervisors and a (12 %) stratified random sample of teachers were chosen for the study. The researcher designed a two-part tool for the study; part one solicited demographic data, and part two contained (30) items on which the respondents were asked to respond in accordance with a four-point Likert scale. Both validity and reliability were determined; the Cronbach Alpha reliability coefficient was (0.92) and the Spearman Brown reliability coefficient was (0.88). Means, percentages, standard deviations, and One-Way Anova were used to analyze the data. The results of the study showed that the teachers and supervisors had negative attitudes towards the use of student guidebooks, and that there were no significant differences in their attitudes with regard to job, specialization, or site of directorate. Meanwhile, there was a significant difference in their attitudes with regard to sex. The results also showed that teachers and supervisors did not overall agree on using student guidebooks by students since their disadvantageous effects on their achievement were apparent. The study recommended that the existing student guidebooks be revised and evaluated, bylaws and regulations regarding their use be made, students be made aware of their disadvantages, and samples of the general examinations questions and key answers be distributed to students and teachers to make use of. | |

Abstract | |
This research is a thorough study of the role of the outstanding scientist, Ibin Al Haitham, in scientific research. Many scholars attribute the development of scientific research to Islamic scientists, among these was Ibin Al Haitham, who initiated the origins of the modern scientific principles. This study I tried to highlight the role of Arab and Islamic traditions in enriching human culture. This role is exemplified through the scientific canon of Ibin Al Haitham. The study also emphasized the urges of transferring the general heritage and the urges of Ibin Al Haitham in particular.The study, further, includes a presentation of Ibin al Haitham’s scientific mission, his manners, his positions and attitudes and major accomplishments. The study also sought to discover Ibin al haitham’s intellectual attitudes and to locate his basic scientific methods, which depended on induction, syllogism, analogy, preference and the hypothetical method. The study then examined the scientific tools and their importance in scientific research through presenting illustrations from Ibin Al Haitham’s works and commenting on them. This research shows the virtues of this outstanding scientist and his distinguished role in scientific research as he touched on the concepts leading to it. The research then concludes with a call for a revival of the legacy and memory of the Islamic scientists who served humanity and made an important contribution to its heritage. | |

Abstract | |
The conventional method for reading/writing information from/on a magnetic media (e.g. magnetic tapes in audio and video recorders, computers etc.) uses what is called an inductive head. This consists of several turns of enemelled wire, wound on a specially prepared former as shown in Fig.1. To write (record) information on the magnetic tape, a modulated current signal is injected into the coil. The current treats (induces) a magnetic field at the free ends of the former (poles) which in turn aligns the magnetic particles deposited on the tape, subsequently producing a record of the injected signal. To retrieve the information (i.e. playback the recorded signals) the prerecorded tape is swiped across the poles of the inductive head. In this case the reverse of the write cycle occurs i.e. the magnetic field from the tape influence the former in such a manner as to cause a current flow through the coil having the same form as the recorded signal. A major disadvantage of this type of head is its speed dependence. Since the head senses the rate of change of field, d?/dt (and not the field itself ? its output becomes greatly dependant' on the speed of the tape. Therefore, in tape system, and using an inductive head, it becomes necessary to use some form of electronic equalization in order to correct errors in the signal, resulting from any variations in the speed of the tape. In addition, because of their bulkiness, they become difficult to implement in applications where high packing densities (video tapes) or multi-track system (computer tapes) are used. A new generation of heads have been developed. The heads use the magneto-resistive effect for the read operation and a simplified inductive approach for the write operation. | |

Abstract | |
Tris (acetylacetonato) cobalt (III), (Co(acac)3), has been used to catalyze o-silylation reactions of R 3 Siff (R.z.Et,Et0) with R OH (Rt-Et, i-Pr, t-.Bu and C6Hj-). No reaction has been observed at room temperature, but the reaction is apparently enhanced when carried out at a higher temperature. The rate of the reaction varies with varying the concentration of the saline or the alcohol. Using different types of alcohols and silanes greatly affects the rate of the reaction. The rate of the reaction is affected by varying the concentration of the complex (Co(acaci6)). | |
