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

When it comes to breakdown issues, Complementary Metal Oxide Semiconductor based class-E power amplifier with a cascode architecture offer excellent reliability. In a cascode setup, a charging acceleration mechanism is included between a common-gate device's drain and source to lessen the power loss of cascode class-E power amplifier. Charge acceleration minimizes the device's power loss by promptly shutting off a common-gate device when a common-source device is switched off. At 28 GHz, the suggested cascode class-E PA with Class D as the preamplifier performs with a maximum saturated outpu

Strategic human resource (HR) metrics, such as employee engagement, training effectiveness, turnover rates, and recruitment efficiency, have been recognized as key drivers of organizational performance. However, limited empirical evidence exists on their direct financial impact, particularly on Economic Value Added (EVA) in the service sector. This study aimed to quantitatively evaluate the relationship between selected HR metrics and EVA, thereby providing insights into the economic returns of strategic HR practices. A quantitative research design was employed, using secondary financial and H

This study examined the impact of leadership styles on teacher performance and student outcomes in secondary schools in the Philippines. Data were collected from 28 school leaders, 84 teachers, and student performance records of 110 learners across both public and private institutions, withrespondents distributed across urban and rural contexts. Leadership styles were measured using the Multifactor Leadership Questionnaire (MLQ), teacher performance was assessed through the Teacher Performance Appraisal Scale, and student outcomes were analyzed using achievement scores and engagement surveys.
