Impacts of the Ban on the Soil-Applied Fumigant Methyl Bromide.

The loss of the soil fumigant methyl bromide (MeBr) and adoption of soil fumigant alternatives has been challenging for farmers, particularly for those crops in which pathogens previously controlled by MeBr have emerged as significant problems, but it has resulted in some unanticipated benefits for the scientific community and the environment. Applauded as one of the most effective environmental agreements to date, the universally accepted Montreal Protocol on Ozone Depleting Substances has had a significant impact on the environment, reducing the release of halogenated compounds from anthropogenic sources enough to mitigate global warming by an estimated 1.1°C by 2021.

Impact evaluation of the TAMANI project to improve maternal and child health in Tanzania.

Background: The Tabora Maternal and Newborn Health Initiative project was a multicomponent intervention to improve maternal and newborn health in the Tabora region of Tanzania. Components included training healthcare providers and community health workers, infrastructure upgrades, and improvements to health management. This study aimed to examine the impact of trainings on four key outcomes: skilled birth attendance, antenatal care, respectful maternity care and patient-provider communication.

The Need for Adult Pneumococcal Vaccination in Nigeria.

Despite universal immunization coverage on a global scale among children, the vast majority of immunocompromised adults, and particularly the elderly, remain unvaccinated. Considering that a significant proportion of mortality from pneumococcal disease occurs among the elderly, preventive measures through pneumococcal vaccination in adults, especially the elderly with co-morbidities, needs to be urgently explored and implemented in Africa, and particularly in Nigeria, to stem the tide of deaths resulting from pneumococcal disease among this population. This article looks at the pneumococcal epidemiology and burden of disease in Nigeria, as well as the vaccines available and the rationale for adult pneumococcal vaccination.

Investigation of arsenic removal from aqueous solution through selective sorption and nanofiber-based filters.

Background: This research paper focuses on removing of arsenic from contaminated water via a nanofibrous polymeric microfiltration membrane, applied in prospective combination with an inorganic sorbent based on iron oxide hydroxide FeO(OH).

Materials And Methods: Nanofibrous materials were prepared by electrospinning from polyurethane selected by an adsorption test. The chemical composition (FTIR), morphology (SEM, porometry) and hydrophilicity (contact angle) of the prepared nanostructured material were characterized.
