Abstract... The study aims to know the attitudes and opinions of postgraduate students at the Libyan Academy, Misurata branch, towards the postgraduate program (Master’s), and to measure their satisfaction with the level of educational, scientific, and administrative service provided to them. Evaluation decisions, according to the degree of students' satisfaction with the quality of service, in the sense of knowing their positive and negative attitudes towards the policies organizing the program.
The sample of students was selected on the basis of a simple, stratified, relative sample. Its size was (300) male and female students from all different scientific disciplines in the seven schools of the Academy, and it represented (7.7%) of the study population, whose size was (3906) male and female students.
The study concluded with a number of results, the most important of which is that (62%) of the students are dissatisfied with the reality of postgraduate studies in the academy, and (70.7%) of the students do not believe that the library is rich in modern and diverse scientific references, and (62.7%) of the students They do not see that the laboratory equipment necessary for the study is available in quantity and quality, and the most important recommendations of the study were a periodic evaluation of the reality of postgraduate studies, improvement of laboratory equipment, the establishment of an integrated scientific library and linking it to international libraries, as well as a comparative study between the branches of the Libyan Academy on the quality of postgraduate studies inside.
Abstract... The research aimed to conduct an estimated study of moisture and some minerals of 16 samples of dried vegetables and fruits, and samples were for apples, pears, carrots and parsley. Among the results that we obtained when dealing with 4 replicates for each types and processing the results using the statistical analysis program Analysis of variance (ANOVA) and Statistical Package for the Social Sciences (SPSS) version 20-2021, we noted the following:
The percentage of moisture ranged between (3.15-4.20), the lowest percentage for the parsley sample and the highest percentage for the apple sample, while the total solids percentage ranged between (95.80-96.85) the lowest percentage in the apple sample and the highest percentage in the carrot sample.
The minerals were estimated in mg/kg for thee two solution obtained wet and dry digestion we observed the following: Sodium, its concentration ranged between (1378.95-10126.49) and (1129.14-10693.05) for the wet and dry digestion solution, respectively, and the lowest concentration in both cases was for the apple sample and the highest concentration in the carrot sample. As for potassium, its concentration ranged between (704.11-2729.29) and (400.55-2780.655). for wet and dry wet digestion solution respectively. And the lowest concentration in both cases for apples and the highest concentration for parsley. Iron concentration ranged between (31.71-71.90) and (3.27-625.12) for the wet and dry digestion solution, respectively. In the wet digestion solution, the lowest concentration was for the parsley sample, while the highest concentration was for the carrot sample in both cases.
Abstract... Digital data obtained by satellites is one of the most important sources of information about the nature of the existing terrain, and it has a role in following up and estimating the extent of change in the natural environments, as it is possible through this data to draw maps of different scales that help in studying and tracking environmental changes in coastal environments.
Libya is a member state of the International Ramsar Convention for the Conservation of Wetlands. The Sabkha of Qasr Ahmed is considered a wetland with high environmental sensitivity due to its biodiversity and being a resting station for some migratory and endangered bird species. The continuous change of land uses in this region leads to an increase of industrial and commercial expansion that led to an increase of residual environmental impacts on the sabkha ecosystem, and a gradual decrease of the sabkha area.
Remote sensing techniques and geographic information systems were used to detect environmental changes in the study area in separate time periods for comparison and to verify the assumed changes. Four satellite images of the Landsat 5-8-9 were used for the years (1973-1984-2016-2022), and were downloaded from the United States Geological Survey (USGS) website, and these images were processed, and analyzed using (ArcGIS).
The results showed changes in the sabkha area during the period from 1973 to 2022, as the area of sabkha decreased from about 342.9 km² in 1973 to approximately 234.7 km² in 2022, which means a loss of approximately 108.2 km² of the area of sabkha due to exposure to many environmental pressures resulting from human activities such as backfilling, dredging, residential purposes, and the use of some sites as a landfill.
Abstract... This study aimed to assess the reality of organizational conflict in higher education institutions in the Libyan city of Misurata, in terms of the different cusses leading to organizational conflict, and the strategies used to remedies these conflict in the organizations under study.
Analytical descriptive approach is used to explain and analyze this phenomenon. The data and information is collected form the community by using the questionnaire. Then these data and information are analyzed by standard statistical methods. The results of these analysis shade light on the number of important real behind the occur and development of the organizational conflict in the Libyan government organizations.
Objectives of the workers are found to be the main cause of personal conflict due to the multi cultures and ideologies among them. There are also organizational reasons such as the lack of clarity in the limits of authorities and responsibilities granted to employees. It was found managers in these organizations practice in one way or another a number of strategies in conflict management, but to varying degrees. The most widely accepted and practiced strategy to manage the conflict is the strategy of cooperation.
Some recommendations were presented, the most important of which is to work on cultivating a culture of difference and accepting the other opinion among the employees of the organizations under study.
Abstract... This research shows the effect of fertilizing using different concentration of eggs shells powder on the production of tomatoes classified as Rio Grande, in comparison with tomatoes that were not fertilized (o), plants were left to flower and set fruit, and calculates the length of stem, number of leaves, number of branches, number of flowers, number of fruits, it weight and the average of leaf's area, the percentage of dry matter, the percentage of water content, chlorophyl (A,B), (A+B), sugars, proteins, proline, the average of some elements of fertilization was estimated , the results show that fertilizing using eggs shells grinded powder had motivated the growth of plants considerably on most growth measures, high increment was noted for each; the length of stem, number of leaves, number of branches, number of flowers, number of fruits, fruits weight, the average of leaf's area, the percentage of dry matter, with a noticeable increment of chlorophyl (A,B), (A+B) sugars, dissolved proteins in the plants juice. check up was done on some elements that are being found in egg shells powder fertilization like sodium (Na), potassium (K), cadmium (Cd), calcium (Ca), zinc(Zn), lead (Pb), while the average of hydrogen number for the egg fertilization (1.88) the moistures content for the egg fertilizer (89:83). Throughout the gained results that have showed that the egg shells fertilizer using the powdered egg shells had an effective role in the growth of seeds and the production of classified tomatoes.
