The introduction of the fifth generation (5G) networks indeed brings significant advancements in connectivity and has the potential to revolutionize various industries. The technologies that make 5G powerful include features such as faster speeds, reduced latency, increased capacity, and the ability to connect a wide range of devices and objects.

However, implementing 5G networks involves upgrading existing infrastructure and deploying new infrastructure, which can be both costly and time-consuming. This process requires significant investments from telecommunication companies to install new equipment and upgrade existing infrastructure to support 5G technology. Additionally, the deployment of 5G networks requires a substantial amount of radio spectrum, and regulatory frameworks need to be in place to allocate and manage the spectrum effectively. This paper provides an overview of 5G technologies, highlighting their key features and potential benefits. It also delves into the existing challenges that arise with the implementation of 5G networks and discusses some possible solutions to address these challenges.

The current research investigates the use of logistic regression as a statistical technique for modelling real blood pressure (BP) data. This study uses a dataset collected from a desert community in southwestern Libya. Six factors that are widely believed to play an important role in the process of BP were considered. Statistical analyses of the available dataset revealed that the main cause of hypertension in such community is age. The proposed multiple logistic regression analysis also revealed that two factors, age and systolic BP, showed greater significance among the six examined variables. These two variables were identified as having a significant effect on blood pressure performance. Based on a determined criterion, each page as the main cause of hypertension in such community participants was classified as hypertensive or not, significant variables were selected based on the p-value associated with the model significance level, and these factors were selected based on the criteria to achieve the model significance level (p < 0.05). The statistical analysis was carried out using R language.

Coronary heart disease (CHD) remains the leading cause of death in DM2. The purpose of this study is to determine the usefulness and effectiveness of exercise electrocardiography (Ex-ECG) and standard two-dimensional echocardiography (2DE) among type 2 diabetic (DM2) and nondiabetic (NDM) of both genders in the diagnosis of CHD accompanied with biochemical risk factors for CHD A total of 102 age-matched DM2 and non-diabetic individuals in both genders were recruited in the current study. All cases were assessed for CHD diagnosis using the Bengali version of the Rose Angina Questionnaire guidelines. Cardiologists examined All groups clinically, and Ex-ECG and 2DE were applied, accompanied by biochemical parameters analysis of all participants in Ematiga's laboratory. All diabetic and non-diabetic subjects are age-matched. The diabetic women were obese with a BMI of (>30 kg/m2 ). The duration of diabetes in females was (10.2±1.02 yrs) and in males was (9.7±0.8 yrs). There was a positive relationship between the duration of diabetes and HbA1c level. Some evidence presented in this study revealed that the percentage of LVEF is negatively correlated with the duration of diabetes mellitus. In addition, there is statistical significance in ST depression between both genders in (ND) and (D) groups. The relationship between ST-depression expressed as mV detected by Ex-ECG and duration of diabetes in females and males. In conclusion, both Ex-ECG, and 2DE testing are non-invasive, easy to perform, and accessible in rural hospitals and clinics. It can be beneficial in diagnosing, risk stratifying or assessing patients with CHD provided appropriate patient selection is used to enhance its sensitivity and specificity, especially in the presence of biochemical risk factors for coronary heart disease explained in this study helped identify or exclude the early diagnosis of CHD.

This study examined effect of potassium drip fertigation on the growth and

fruit yield of tomato under field conditions at western Libyan conditions, in two

consecutive seasons. The soil texture sites was sandy, pH around 8.0. the soil potassium

was extracted and estimated by flam photometer at 766 μm. The rate of potassium fertilizer

were F1: 0; F2: 150; F3: 300 kg K2O ha-1 as potassium chloride form in three replicates.

The experimental site was designed in randomized complete block (RCBD). and I1: 75%

ET𝑐; I2: 100% ET𝑐; I3: 125% ET𝑐 levels for irrigation. The interactions for both potassium

fertilization levels and irrigation treatments with fruit yield were found. The single

treatments of potassium fertilization or irrigation significantly affected the tomato fruit

yield, where fertilization and irrigation applications increased the fruit weight from 13.99 t

ha-1 to 34.47 t ha-1 t/ha minimum in F1I1 and maximum in F3I3. Application of different Kfertilizers

and irrigations had significant effect in PFP (partial factor productivity), and

AUE (agronomic use efficiency) as compared to K-control plots of tomato. The average of

PFP for K and irrigation in two treatments were 65.65 kg kg-1 in F2I3, and 59.43 kg kg-1 in

F3I3 which are greater than the values of control, F1I1, F1I2, and F1I3 treatments
