This study aims to develop High-Performance Concrete (HPC) using materials readily available in local markets within the Kingdom of Saudi Arabia (KSA). The primary objective is to achieve compressive strengths exceeding 70 MPa by optimizing concrete mix designs through a series of experimental trials. The methodology involves incorporating varying percentages of silica fume (SF) as a mineral admixture alongside locally sourced aggregates, including crushed stone and quartz sand. The paper focuses on evaluating the effect of silica fume concentration on key performance indicators of HPC: compre

This work discusses the optimal proximity fixed point theorem applicable to non-self-mappings within complete G-metric spaces. The study defines the essential and adequate conditions for the existence of such points. There is also a fixed-point theorem in the paper that is based on the main finding. Then, the theoretical results are applied to analytic functions of a complex variable, showing how useful these abstract results can be in real life. The paper demonstrates that theorems related to best proximity and fixed points can be applied in areas beyond pure mathematics in more than just pur

This study was to ascertain the effect of friendzone to the emotions and self-esteem of learners in elementary and secondary schools. The study used a descriptive-documentary and survey design. The respondents were the 251 teachers, and 120 learners. The questionnaire used was modified and adapted [2], while the learners’ academic performance was documentary taken from their respective advisers through the approval of their school head. The result revealed that the respondents were emotional which leads to engage into a relationship. Moreover, there is a significant relationship between the

The word "obesity" is well-defined as person having BMI of 30 kg/m² or greater than it. Obesity shows a very negative influence on most of the systems or organs, like impact on the reproductive system. This study aims to analyze the relationship of serum and ultrasound markers of ovarian function with BMI in menstruating women. The cross-sectional research was held at IIMCT Railway General Hospital Rawalpindi and it includes 140 participants, i-e 70 obese and 70 non-obese women. Blood specimens were drawn on third day of their menstrual cycle to evaluate hormonal markers. While ultrasound mar

Novel frameworks addressing distinct challenges in technology and network optimization. Firstly, GAN-based framework enhances Botnet prediction using advanced image processing techniques such as S-GF filtering, GDA tone mapping, and IGM for boundary enhancement. The framework includes feature matching and clustering with KL- HM-KMA to predict Botnet effectively, validated through comprehensive experimental analysis. Secondly, in the realm of sensor network applications with mobile sinks, a new framework employs DFS-A* and A-BOTNET algorithms. It optimizes data gathering by dynamically consider
