Article Synopsis
  • This study investigates the greenhouse gas emissions from prescribed fires using a carbon mass balance approach across 80 experimental plots.
  • It finds that grass and shrub savannas produce higher carbon emissions due to intense burning, while tree savannas and woodlands show higher emission factors despite lower total emissions, due to their high biomass carbon content.
  • The research emphasizes that vegetation types and climate zone interactions significantly affect carbon emissions and highlights the need for better measurement and reporting of GHG emissions from fires.

Background: Drug resistance in tuberculosis poses challenges to both the control and prevention of the disease. The extent of resistance is not well known in developing countries, including Ethiopia. This study was conducted to determine the drug resistance patterns and mutation characteristics of among extra pulmonary tuberculosis patients in selected health facilities in Addis Ababa.

Agricultural practices such as repeated fertilization impact carbon (C), nitrogen (N) and phosphorus (P) cycling and their relationships in the plant-soil continuum, which could have important implications for the magnitude of greenhouse gas emissions. However, little is known about the effect of C and N additions under contrasting soil P availability status on nitrous oxide (NO) and carbon dioxide (CO) emissions. In this study, we conducted a field-based experiment that investigated the impact of long-term (23 years) P management (no (P0, 0 kg P ha), low (P15, 15 kg P ha) and high (P45, 45 kg P ha) P inputs) on NO and CO emissions following two C + N application events in two managed grassland ecosystems with loam and sandy loam soils.

Background: The early postnatal period is a dangerous time for both mother and baby where morbidity and mortality are highly prevalent if proper care is not done. Post natal care (PNC) knowledge has significant role in reducing such complications. In this study, the knowledge of postpartum mothers on PNC and its determinants were determined.
