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

Using Interactive Whiteboard to Enhance Learning Process for Dyslexic Children
Journal ArticleDyslexia is a distinct learning disability that is distinguished by difficulties in decoding and reading fluency, spelling as well as other cognitive skills. This research is conducted to assist learning disability by improving the skills required for children with learning disability in reading and spelling using the assistive technology AVA interactive whiteboard. The approach is by strengthening the micro skills required to improve the fundamental skills such as reading, and spelling thus facilitating the learning process. Tactile and visual modalities are the main focus in the use of the interactive whiteboard. This study aims to develop an interactive whiteboard learning prototype for students with dyslexia. A total of six children from 3 demographics (Chinese, Malay, and Indian) participated in the study. Activities improving the four micro skills were introduced in normal whiteboard and the children were exposed to the prototype AVA interactive whiteboard. Responses using Interactive whiteboard were different when compared to their performance with the normal whiteboard. The analyzed results indicated showed improvements in three of the micro skills using IWB

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.

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.

Cupping is an element of prophetic medicine, as it has achieved remarkable successes that have attracted attention and are still rising today to be considered the third treatment in terms of importance after acupuncture and massage. Wet Cupping works to activates blood circulation and opens the pores of the skin, which contributes to removing pathological effects, lowering blood pressure and pulse, and reducing the amount of sugar in the blood. This study aims to evaluate the effectiveness of Wet Cupping in treating blood pressure and compare it with the treatment used by presenting an analytical comparison between 20 blood pressure patients from the city of Gharyan, of both sexes, whose ages varied from 45 to 80 years. The cases were divided into two groups. 10 people were described as the control group, the blood pressure of each of them was measured two hours before and after taking the treatment. 10 people who were in the control group, had their blood pressure measured two hours before and after cupping during three sessions that lasted 45 days. Based on the comparison between the results of blood pressure measurements before and after Wet Cupping for both the groups obtained from the study sample using statistical studies, it was found that cupping has the same effect treatment in maintaining the blood pressure level.

Hemoglobin is one of the body's important proteins as it carries out the function of transporting oxygen from the lungs to the rest of the body's organs and parts, and returning carbon dioxide from different parts of the body to the lungs, but an increase in the percentage of hemoglobin in the blood above the normal rate is a pathological condition that results in many symptoms, the most important of which are feeling tired, high blood pressure and inability to breathe. The main reason for this condition is the increased production of red blood cells in the spinal cord, which is caused by a deficiency in the amount of oxygen in the blood. Smoking is one of the main causes of a deficiency in the amount of oxygen in the blood, as this study aims to clarify the extent of the effect of smoking on increasing the percentage of hemoglobin in the blood, by presenting an analytical comparison between 200 cases in the Gharyan area (100 cases of smokers and 100 cases of non-smokers) ranging in age from 18 to 80 years. A complete blood count (C.B.C) test was performed on all blood samples obtained. The results obtained from the study sample were compared using statistical studies, which showed that the hemoglobin percentage of blood samples from smokers was higher compared to the hemoglobin percentage of blood samples from the non-smokers group. The results also showed that the relationship between age and 79 | African Journal of Advanced Pure and Applied Sciences (AJAPAS) hemoglobin percentage in the blood of the smokers' group was weak and almost non-existent, while in the non smoker's group the relationship was inverse, meaning that the older the age, the lower the hemoglobin percentage, and this may be due to some other reasons.

?Is Ultra-Wideband UWB reconfigurable to Bluetooth
Conference paperIn this paper, deploying an integrator, we propose a method to transform ultra wideband (UWB) signal into a frequency hopping type of transmission signal that is applied in Bluetooth technology. In addition to the tremendous increase in data transfer speed, the frequency domain equalization is further extended to Bluetooth technology, as a result. This paper further shows that both technologies can be deduced from each other although UWB is a carrierless while Bluetooth requires a transmission carrier.
