This article reviews the impact of biomedical waste on water, soil, air quality, the environment, and human health. Hospitals and nursing homes generate increasing amount of biomedical waste in an unscientific manner. As such, poor waste management practices by these institutions cause exposure to health hazards and actual environmental problems. The issue of biomedical waste identification, handling, and disposal needs to have a heightened review so that better management practices and protocols can be established.

Solar energy is one of the promising renewable energy sources which has the potential to meet the future energy demand around the world. To maximize the irradiance fall, solar panels are generally equipped with a motor tracking system and are placed at a specific tilt angle. However, tracking methods are not cost‐effective and a fixed tilt angle is not productive. This study proposes a method for harnessing maximum output from photovoltaic (PV) panels throughout the year by determining the optimal tilt angle. The investigation is performed on real‐time solar PV panels of 5 kWp rated capacity installed at 10°, 20°, 25°, 30°, and 40° angle on the rooftop of engineering institute situated at Chandigarh, India. The real‐time power generation response for a year is used to find the optimal tilt angle. The results obtained from the practical setup are validated by comparing it with the simulation results of the regression analysis. In addition, the impact of the optimal angle on total power generation and carbon emissions is analyzed. The results reveal that the proposed approach is quite effective to increase the power generation of PV panels up to 7–8% and can be practically implemented in any location throughout the world.

With the development of wireless communication technology, various wireless networks have been deployed. Heterogeneous networks will be dominant in the next generation wireless networks. In such networks, providing a seamless handoff by selecting the appropriate network is one of the key issues. In order to be always best connected for various applications, the network selection procedure, in heterogeneous multi-access environment during vertical handover decision is intended to choose the most suitable network for mobile user. In this paper, a handoff decision scheme is proposed that will help to choose the correct network and fuzzy logic is applied to deal with the imprecise information of some criteria and user preference.
