HIV/AIDS has emerged as a serious public health issue across the globe, and particularly in developing countries. Comprehensive knowledge positive attitudes are cornerstones for prevention, control treatment of HIV/AIDS. However, there various misconceptions associated with transmission, which lead to negative towards people living AIDS. The present study aims explore effects these determinants, related socio-demographic characteristics autonomy, on women's overall regarding Pakistan.

Background: Bronchiectasis is a chronic respiratory disorder characterized by irreversible bronchial dilation, impaired mucociliary clearance, and recurrent infections, leading to progressive pulmonary dysfunction. Airway clearance techniques play crucial role in managing symptoms improving function. The active cycle of breathing technique (ACBT) widely used physiotherapy intervention, often combined with postural drainage (PD) or autogenic (AD). However, comparative evidence regarding their...

Soil pH is a critical characteristic that regulates the abundance of essential nutrients in soil system. Low reduces supply secondary macronutrients, whereas higher restricts micronutrient availability. In addition, nutrient sources such as organic and inorganic fertilizers by plants require an adequate for optimum plant growth productivity. The regarded "master indices", which has role to play controlling biogeochemical cycles influence growth. It also enormous on microbial biodiversity...
