Nano-Restoration for Sustaining Soil Fertility: A Pictorial and Diagrammatic Review Article.

Soil is a real treasure that humans cannot live without. Therefore, it is very important to sustain and conserve soils to guarantee food, fiber, fuel, and other human necessities. Healthy or high-quality soils that include adequate fertility, diverse ecosystems, and good physical properties are important to allow soil to produce healthy food in support of human health.

Planning for disposal of COVID-19 pandemic wastes in developing countries: a review of current challenges.

The health sector is critical to the well-being of any country, but developing countries have several obstacles that prevent them from providing adequate health care. This became an even larger concern after the COVID-19 outbreak left millions of people dead worldwide and generated huge amounts of infected or potentially infected wastes. The management and disposal of medical wastes during and post-COVID-19 represent a major challenge in all countries, but this challenge is particularly great for developing countries that do not have robust waste disposal infrastructure.

Nano-biofortification of different crops to immune against COVID-19: A review.

Human health and its improvement are the main target of several studies related to medical, agricultural and industrial sciences. The human health is the primary conclusion of many studies. The improving of human health may include supplying the people with enough and safe nutrients against malnutrition to fight against multiple diseases like COVID-19.

Analysis of the caesarean section rate using the 10-Group Robson classification at Benha University Hospital, Egypt.

Background: Egypt has the third highest caesarean section rate (54%) in the world and lacks a standard classification system to analyse caesarean section rates. The World Health Organization (WHO) recommends the Robson classification as an effective caesarean section analysis and monitoring tool.

Aim: To analyse the caesarean section rate of Benha University Hospital, Egypt using the standard 10-Group Robson classification system.

Uptake of nicotine from discarded cigarette butts - A so far unconsidered path of contamination of plant-derived commodities.

This study aimed to elucidate the origin of the widespread nicotine contamination of plant-derived commodities, by conducting field experiments with various herbs and spice plants. By scattering tobacco and cigarette butts on the field and subsequent nicotine analyses of the acceptor plants, we verified that the alkaloid is leached out into the soil and is taken up by the crop plants. This path of contamination pertains even when there is only one cigarette butt per square meter.
