This study aimed to compare the information system security in two banks in Gharyan city and to numerous challenges that face banks, which can severely affect customer trust and financial stability. In order to achieve the objectives of this study, the researcher used the analytical descriptive method relying on the questionnaire and interviews as main tools to collect banking data collection for the two banks, which they are Jumhouria Bank of Gharyan, and North Africa bank of Gharyan. This study came up with a series of findings includes theprotectionthe banking information system security is quite safe. As well as recognize the types of risks that may occur in these bankssuch as infecting the system's devices with viruses also internal and external penetration of banks information system and how these risks impact, as result of that, this study recommends a multi-layered approach including utilize automated tools to continuously scan for known vulnerabilities in applications and systems. This helps in early detection of potential they can be exploited. In addition, banks must effectively update programs that protect against viruses and download only reliable antivirus programs moreover banks must continuous training for employees on security information system.

pH Role in Green Synthesis of Silver Nanoparticles Using Extract of various Plant Parts: A review
Journal ArticleSynthesizing silver nanoparticles (AgNPs) from extracts of various plant parts
and of agricultural waste is strongly affected by pH. These green synthesis
methods cconsidered simple, cost effective, ecofriendly, and biologically
effective. This brief review aimed to survey the role of pH in the green
synthesis of AgNPs using those media, with a focus on its effect on AgNPs
morphology and size. This review article revealed that the alkaline pH (9 -
10) is the optimum condition for synthesizing more stable and tiny uniform
AgNPs. In addition, according to the reviewed articles, the spherical shape is
the most dominant shape of these articles in the basic medium and the size of
these particles decreases at elevated pH values and ranged from 5-40 nm

Effect of Applying Nd-YAG Laser on Microstructure and Hardness of AISI 1012 Steel Surface
Journal ArticleThe unique characteristics of the laser beam compared to the normal light i.e. its directionality, monochromatcity, and brightness make it a very important tool in the surface engineering. The concentrated heat in the laser beam can precisely directed toward the processed region on the surface. The laser beam power, size, and scanning velocity are easily controlled during the different processing methods. Laser surface modifications of metallic materials, such as laser surface melting, laser surface alloying, and laser cladding are some of the most important methods to improve the mechanical properties of the processed layer on the surface. A pulsed Nd-YAG laser surface melted specimens of low carbon steel with a maximum power of 90W at different processing parameters. The rapid melt and resolidification of the treated layer produced a refinement in the microstructure. The original microstructure of this steel (Ferrite + Pearlite) has been transformed to new phases of martensitic and bainitic structures. The melted layer consists of the melted pool, the heat affected zone, and the substrate. The maximum hardness of the laser melted layer is more than 400 HV.
Key words:Laser surface Melting, Carbon steel, Microstructure, Microhardness

دراسة مستويات بعض المتغيرات الكيموحيوية لمرضى السكري النوع الاول والثاني في مدينة غريان
مقال في مجلة علميةDiabetes mellitus is a common disease that occurs as a result of uncontrolled blood sugar levels, which over time leads to a disturbance in the metabolism of carbohydrates, proteins and fats in 268 | Afro-Asian Journal of Scientific Research (AAJSR) the body. This study was conducted on patients with type 1 and type 2 diabetes and a sample of healthy people to study some biochemical variables (triglycerides, cholesterol, urea, and creatinine), as it included 157 people with type 1 diabetes, 157 people with type 2 diabetes and 50 healthy people to be used as a control factor. The ages of patients and healthy people ranged from 15 to 96 years in the period from June to October of the year (2022). The results of the study showed a significant increase in the concentration of triglycerides, cholesterol and Creatinine in type 1 diabetes patients compared with the healthy group, while no difference was observed in the level of urea compared with the healthy group, while the results showed a significant increase in the concentration of all variables triglycerides, cholesterol, urea, creatinine in type 2 diabetes patients when compared with the healthy group. To be concluded from this, the high blood glucose levels have an effect on some biochemical variables in diabetic patients compared with healthy individuals.

الكشف عن صبغة سودان رد B في بعض العصائر والمشروبات الغازية المتوفرة بالأسواق المحلية - ليبيا
مقال في مجلة علميةالملخص:
في وقتنا الحالي يتزايد الطلب على الملونات التي قد تكون ضارة عندما تكون ملونات صناعية لتلوين مُختلف الأطعمة ومنها العصائر والمشروبات الغازية المختلفة، لدعم لون المنتجات والتأثير على حواس المستهلك والتي تلعب دوراً حاسماً في تسويق المنتج، من بين الأعداد الكبيرة من المواد المستخدمة في التلوين والأصباغ الاصطناعية المنتشرة في هذه الصناعة. صبغة السودان ردB صبغة حمراء اللون والتي استخدمت في الصناعة وخاصة إنتاج صبغات الشعر والمستحضرات التجميلية، ولا تزل بعض البلدان تستخدمها كمضافات غذائية رغم حظر استخدامها في صناعة المواد الغذائية بسبب تأثيرها المحتمل للسرطان. وتم تصنيفها ضمن الفئة الثالثة للمواد البشرية المسرطنة من قبل الوكالة الدولية لأبحاث السرطان. ومن المهم وصف آثارها الضارة على الصحة والمستهان بها في الوقت الحاضر. توجد طرق عديدة للكشف عن وجود صبغة السودان رد.B وفي هذه الدراسة تم استخدام جهاز التحليل الطيفي للكشف عن وجود صبغة السودان رد B عند طول موجي 525 نانومتر في عينات متنوعة من العصائر والمشروبات الغازية من بلدان مختلفة الصنع والمتوفرة في الأسواق المحلية الليبية.

Detection of Eimeria Parasites in Sheeps and Goats in Alhamada Area, Libya
Journal ArticleSince the Alhamada area is known for its rangelands and most of its inhabitants raise animals, especially sheep and goats, this study was conducted by collecting samples randomly from six herds of sheep distributed randomly from the specific areas of Qurayat and Ghadames This study was aimed to determine the prevalance of Eimeria, which causes coccidian in sheep's and study the effects of many factors such as age, sex, and the breeding system, it is the first study conducted in the Hamada area on this parasite, using microscopic examination, 54 samples of sheep and goat feces were examined, of different ages and of both sexes in the month of May 2022. The result showed that the infection rate was 28% in sheep and 43% in goats. It was noted that there were no significant differences for age in the infection rate, as the highest infection rate was in the age group (>2) years (39%), while the lowest infection rate was in the age group of (1-2) years (7%), it was also shown that there is no significant difference for gender on the infection rate, as the infection rate in males was (22%) and females (48%). The results showed a slight difference in the infection rate between the open and closed breeding systems in the Hamada region, with the closed system averaging 25% compared to 20% in the open system. Clinical signs also appeared on some of the infected animals, including diarrhea, general weakness, and some of them showed plucking of wool/hair.
