Objectives: This article aims to discover the impact of the coronavirus pandemic lockdown on diabetes patients living in Almadina, Saudi Arabia, in terms of their lifestyle and on their follow-up. Methods: This is a cross-sectional, qualitative prospective study, a questionnaire was done to diabetic patients who underwent the quarantine period in Madinah, Saudi Arabia through an online questionnaire after getting informed consent to participation. The survey included personal, medical data, patient’s compliance to treatment and overall lifestyle manner before and during lockdown period and psychological assessment using 10 questions of the (K10) Kessler psychological distress scale. Data analysis was performed using SPSS program version 26. Results: A total of patients 350 participated in the study. 56.6% of them were females(n;198), and 43.4% were males(n:152), their ages ranged from 18 years to more than 60 years. The vast majority 96.3% of participated were of Saudi nationality, while 3.7% are non-Saudi. Participants-with types 2 Diabetes represent 31.4% while 26% suffer from type 1 diabetes and the rest they don’t which type they have. Results showed no significant differences in: (symptoms of low or high blood sugar, the extent to which a healthy diet is followed, the frequency of home blood sugar measurement) before and during the quarantine period. The rest of the variables shows a significant difference (P

The main objective of this paper is to investigate the main challenges that startups face in Saudi Arabia. It tries to identify the wave of opportunities that come along with startups and analyze the main factors for success and sustainability. A sample of 40 respondents was established. According to the survey results, consumer-oriented activity dominates startup activities. Startups remain mainly dependent on non-equity funding. The first challenge that startups encounter is finding funding. Saudi startups are more focused on product innovation. Most of the respondents think that aspects of the entrepreneur's personality and skills play a significant role in the success of startups.

Micronutrients support immune functions and are essential for optimized health and production of animals. This study was conducted to evaluate the effect of vitamin E and vitamin C, alone or in combinations, on growth and antioxidant capacity of neonate dairy calves. For this purpose, eighteen female Holstein Friesian calves were selected. Experimental treatments were; T0 or control (milk without vitamin supplementation), T1 (milk supplemented with 250mg of vitamin E), T2 (milk supplemented with 500mg of vitamin E), T3 (milk supplemented with 1000mg of vitamin C), T4 (milk supplemented with 250mg of vitamin E and 1000mg of vitamin C) and T5 (milk supplemented with 500mg of vitamin E and 1000mg of vitamin C). Experimental treatments were started from the third day till 60th days of calf’s life. Blood was collected in clot-activator tubes for TAC at day 01, 30 and 60. Body measurements were noted during 1st, 3rd, 6th and 9th week of this trial. Results showed that the TAC was significantly high in T1 group during first month. At the end of the trial (day 60), TAC were highest in T0 and T1comparetively. The wither height, heart girth and body length were significant in supplemented groups compared to control. In conclusion, it is asserted that the supplementation of vitamin E and vitamin C have beneficial effect on growth and antioxidant capacity of neonate calves.

بينت التطورات العلمية الحديثة وجوب ايجاد طرق قياس تمتاز بالدقة ، البساطة والسرعة وتدخل ضمن الكيمياء الخضراء . في هذه الدراسة تم استحداث طريقة لقياس تركيز ايون المنغنيز الثنائي في ازهار بعض النباتات الطبية بأستعمال تقنية الحقن الجرياني المستمر باستعمال بيروكسيد الهيدروجين في وسط قاعدي لأكسدة المنغنيز الموجود في النبات الى Mn+7 (برمنجنات البوتاسيوم) ذات اللون البنفسجي حيث تم قياسه بواسطة منظومة محلية الصنع عند طول موجي 540 نانومتر وتحت ظروف قياسية حيث كانت سرعة الجريان 1.8 مل / دقيقة لبيروكسيد الهيدروجين وهيدروكسيد البوتاسيوم. وكانت لهذه الطريقة خطية ضمن المدى من 0.10 الى 36.0 ملغم/لتر، مع حدود كشف 1.080 ملغم/لتر ونسبة استردادية مؤوية (RDS %) 1.7 %. تم اخذ نموذج 10 ملغم من الازهار المجففة المطحونة لاربعة نباتات طبية مختلفة ( Matricaria recutita, Lavandula angustifolia , Viola , Gardenia ) ان هذه الطريقة المطورة كانت ناجحة بتقدير المنغنيز فقد اظهرت المقارنة الاحصائية بين الطريقة المستحدثة والطريقة القياسية , طيف الامتصاص الذري , انه لا يوجد فرق معنوي بين الطريقتين لذلك من الممكن استعمال الطريقة المستحدثة كبديل للطرق التحليلية المثبتة في الدساتير العالمية لتقدير المنغنيز.

China has entered a new fifth-generation (5G) technological period, college students are relatively fast to absorb new things, and conventional teaching methods are incapable of properly stimulating students’ interest in sporting activities. As a result, the 5G integrated teaching paradigm, which is based on communication technology, is an unavoidable reform of sports remote education. For a long time, technology and sports have been inextricably linked. However, new possibilities on the Internet are fast developing, resulting in massive volumes of data. In this paper, we propose a novel 5G framework for efficient sports distance education. Initially, the sports dataset is preprocessed using normalization, and the features are extracted using Principal Component Analysis (PCA). Following feature selection, a Hierarchical Multiscale Convolutional Neural Network (HM-CNN) is used to categorize and initialize the 5G utilizing the Enhanced Transfer Control Protocol (E-TCP) for efficient data transmission. The Elevated Ant Colony Optimization Algorithm improves the performance of the suggested system even more (EACO). The experimental results indicate that 5G integrated education reform based on communication technology may successfully enhance the number of college students’ sports population.
