This study was carried out to prepare and characterize domperidone nanoparticles to enhance solubility and the release rate. Domperidone is practically insoluble in water and has low and an erratic bioavailability range from 13%-17%. The domperidone nanoparticles were prepared by solvent/antisolvent precipitation method at different polymer:drug ratios of 1:1 and 2:1 using different polymers and grades of poly vinyl pyrolidone, hydroxy propyl methyl cellulose and sodium carboxymethyl cellulose as stabilizers. The effect of polymer type, ratio of polymer:drug, solvent:antisolvent ratio, stirring rate and stirring time on the particle size, were investigated and found to have a significant (p? 0.05) effect on particle size. The best formul

This study aims to investigate the academic leaders’ perceptions towards the degree of availability of the dimensions of organizational immunity systems at the University of Tabuk, as well as to reveal the statistically significant differences between the average responses of the study sample members about the degree of availability of these dimensions at their university due to the variables of (gender, leadership position, and college specialization). To achieve the objectives of the study, a descriptive survey method was used. The study population consisted of (200) male and female leaders who were academic leaders at the University of Tabuk. A questionnaire was used as a tool for collecting data, which its validity and reliability

In recent years, the attention of the international community and intergovernmental and non-governmental organizations has grown into a new dimension of population displacement, called displacement within the country as a result of conflicts and the expansion of tacit groups, using sentences to describe such conflicts as "identity-based conflict", "ethnic conflict" "Sectarian conflict", in an attempt to determine the nature and characterization of those conflicts. In such conflict-stricken conditions, the value of a citizen - a person not directly involved in the conflict - is measured by the potential gains that that person has made to the conflicting parties, as civilians have been indirect victims of military operations, Favor

يهدف البحث الى دراسة وتحليل التمويل الأخضر كأحد المفاهيم الاساسية والحديثة في عالم الاعمال والاقتصاد العالمي وخاصة بعد الازمات والتحديات التي توالت على العالم نتيجة الكوارث الطبيعة وتغييرات المناخ والضغوطات على الموارد الطبيعية والتي أدت الى احداث اثرا كبيرا في اقتصاديات الكثير من الدول ، مما اضطرت الى إعادة النظر في مشاريعها وانشطتها الاستثمارية بما يوائم وطبيعة البيئة ومتغيراتها ، لذا تحتم اختيار لمثل

The apricot plant was washed, dried, and powdered after harvesting to produce a fine powder that was used in water treatment. created an alcoholic extract from the apricot plant using ethanol, which was then analysed using GC-MS, Fourier transform infrared spectroscopy, and ultraviolet-visible spectroscopy to identify the active components. Zinc nanoparticles were created using an alcoholic extract. FTIR, UV-Vis, SEM, EDX, and TEM are used to characterize zinc nanoparticles. Using a continuous processing procedure, zinc nanoparticles with apricot extract and powder were employed to clean polluted water. Firstly, 2 g of zinc nanoparticles were used with 20 ml of polluted water, and the results were Tetra 44% and Levo 32%; after

To achieve the goals, the researcher followed the design of equal and   independent groups of partial control and post-test . The research has chosen the Institute of Fine Arts in the area Almansour area as deliberate sample where three sections of students have been chosen and the   number of students is (69) students. The researcher conducted equivalence in the variables (age, and IQ , and the overall rate for grade III). in diagnostic phase,  (21) concepts of alternative    image out of (46) concepts have been identified in addition to the goals of formulation of acquisition concepts according to the three processes (definition, discrimination and application). Achievement test has been
