Policies and regulations for solar photovoltaic end-of-life waste management: Insights from China and the USA.

The solar photovoltaic (PV) industry has experienced rapid growth in recent years, resulting in a substantial increase in the amount of end-of-life (EOL) waste generated by these panels. Proper waste management is crucial to minimize environmental and health risks. The purpose of this study is to examine the EOL solar PV waste management policies and regulations in China and the United States, identifying challenges and recommending policy implications for enhancing sustainable waste management practices.

Cellulose/inorganic nanoparticles-based nano-biocomposite for abatement of water and wastewater pollutants.

Nanostructured materials offer a significant role in wastewater treatment with diminished capital and operational expense, low dose, and pollutant selectivity. Specifically, the nanocomposites of cellulose with inorganic nanoparticles (NPs) have drawn a prodigious interest because of the extraordinary cellulose properties, high specific surface area, and pollutant selectivity of NPs. Integrating inorganic NPs with cellulose biopolymers for wastewater treatment is a promising advantage for inorganic NPs, such as colloidal stability, agglomeration prevention, and easy isolation of magnetic material after use.

Environmental impacts of hazardous waste, and management strategies to reconcile circular economy and eco-sustainability.

The rise in living standards and the continuous development in the global economy led to the depletion of resources and increased waste generation per capita. This waste might posture a significant threat to human health or the environmental matrices (water, air, soil) when inadequately treated, transported, stored, or managed/disposed of. Therefore, effective waste management in an economically viable and environmentally friendly way has become meaningful.

A research on conventional and modern algorithms for maximum power extraction from wind energy conversion system: a review.

In the last few decades, wind energy has become a significant source of the renewable energy system, and it is essential to use wind energy for generating power and run the wind turbine system (WTs) at a higher level. With the rapid penetration of wind energy in the distributed generation system (DGS) and isolated micro-grid (MG), the WT runs at its optimal energy conversion output. For this, WT has to track or drive at the optimal power point tracking algorithm.

Solar still desalination system equipped with paraffin as phase change material: exergoeconomic analysis and multi-objective optimization.

The current work is about analysis and multi-objective optimization (MOO) of weir-type solar still systems equipped with phase change material (PCM) regarding the exergetic and economic performance. To do so, the energetic and exergetic modeling of the suggested system is conducted then the substantial economic factors is applied to obtain the total cost rate of the considered SSDS. The total exergetic efficiency and total annual cost (TAC) is considered objective functions.

Breast cancer screening practices and awareness in women admitted to a tertiary care hospital of Lahore, Pakistan.

Objective: To assess the awareness and practices of women with regard to breast cancer and its different methods of screening.

Methods: A descriptive cross-sectional study was carried out in the inpatient wards of Fatima Memorial Hospital, Lahore. By convenience sampling, 200 female inpatients were selected.

Perceptions and practices of a pakistani population regarding cervical cancer screening.

Cervical cancer is among the three leading causes of cancers among females worldwide. It is also among the three most common causes of cancer deaths among females, about 80% of which occur in less developed countries. The present cross-sectional knowledge, attitude and practice survey was carried out to determine the perceptions and practices of a Pakistani female population regarding cervical cancer screening.
