Perspective on the status and behaviour of SARS-CoV-2 in soil.

Soil contamination by SARS-CoV-2 is highly probable because soil can collect several transporters of the virus, such as fallout aerosols, wastewaters, relatively purified sludges, and organic residues. However, the fate and status of SARS-CoV-2 in soil and the possible risks for human health through contaminated food are unknown. Therefore, this perspective paper discusses the challenges of determining the SARS-CoV-2 in soil and the mechanisms concerning its adsorption, movement, and infectivity in soil, considering what has already been reported by perspective papers published up to May 2021.

Artificial neural network modeling for Congo red adsorption on microwave-synthesized akaganeite nanoparticles: optimization, kinetics, mechanism, and thermodynamics.

This work aims to synthesize akaganeite nanoparticles (AKNPs) by using microwave and use them to adsorb Congo red dye (CR) from the aqueous solution. The AKNPs with an average particle size of about 50 nm in width and 100 nm in length could be fabricated in 20 min. The effects of pH, CR initial concentration, adsorption time, and adsorbent dosage on the adsorption process were investigated and the artificial neural network (ANN) was used to analyze the adsorption data.

Proteolytic Activity in Meadow Soil after the Application of Phytohormones.

Phytohormones, similar to soil enzymes, are synthesized and secreted into the soil environment by fungi and microorganisms. Phytohormones are involved in regulating microbial community activity in the rhizosphere. This paper examines how auxins, cytokinins, ethephon and chlorocholine chloride affect the activity of native soil proteases in the organo-mineral horizon of an alpine meadow.

Medical and salutogenic approaches and their integration in taking prenatal and postnatal care of Czech women.

Objective: To compile a proposal of the system of taking complex prenatal, perinatal and postnatal care of pregnant women and their children in the Czech Republic with taking into account medical and salutogenic approaches.

Material And Methods: A questionnaire was prepared comprising questions for mothers and making it possible to exactly use specified data from their healthcare documentation. The method thus consisted of a secondary data analysis and subsequent contact with mothers.

Medical and salutogenic approaches and their integration in taking prenatal and postnatal care of immigrants.

Objectives: To compile a proposal of the system of taking complex prenatal, perinatal and postnatal care of pregnant immigrants in the Czech Republic with taking into account medical and salutogenic approaches.

Material And Methods: The research was implemented by the form of a controlled interview and was based on a questionnaire comprising 50 questions focused on the evaluation of taking the prenatal, natal and postnatal care of immigrants. The data were accumulated among immigrants from Vietnam, Mongolia and Ukraine.
