A nanocellulose from sugarcane bagasse as a template for nickel oxide nanoparticles for removal of organic dyes from aqueous solution.

The aquatic ecosystem is negatively impacted by organic dye contamination, which is now one of the factors leading to environmental pollution. The present investigation involved the synthesis of nanocellulose (NC) and nanocellulose modified with NiO (NC/NiO) composite using acid hydrolysis and a one-step precipitation technique for NC and NiO, respectively. Malachite green (MG) dye was catalytically removed from an aqueous solution using the two products, which were mechanically homogenized.

Tsetse fly density and trypanosoma infection rate in Bedele and Dabo Hana districts of Buno Bedele Zone, Southwest Ethiopia.

Background: Trypanosomiasis is an infectious disease caused by parasitic protozoa of the genus Trypanosome and primarily transmitted by tsetse flies. This study aimed to determine the density of tsetse flies and the rate of trypanosome infection in the Bedele and Dabo Hana districts of the Buno Bedele Zone in Ethiopia.

Results: A cross-sectional study was conducted from January to February 2023 to catch tsetse flies, determine tsetse density, and estimate the trypanosome infection rate.

Forage yield and nutritive value of Desho grass ( Trin.) as affected by cutting heights in the central highlands of Ethiopia.

Desho grass (Pennisetum glaucifolium Trin) an important fodder grass. However, information on its production is lacking. This study was carried out to evaluate the forage dry matter yield and nutritive value of Desho grass harvested at different cutting heights (CH), under rain-fed conditions in two different sites in central highlands of Ethiopia for two years.

Synthesis of Kaolin-Supported Nickel Oxide Composites for the Catalytic Oxidative Degradation of Methylene Blue Dye.

Organic dye contamination of water is a contributing factor to environmental pollution and has a negative impact on aquatic ecology. In this study, unsupported NiO and kaolin-supported NiO composites were synthesized by a one-step wet impregnation-precipitation method through the precipitation of nickel hydroxide onto locally accessible, inexpensive, and easily treated kaolin surfaces by using sodium hydroxide as a precipitating agent. The product was calcined at 500 °C and used for the catalytic oxidative degradation of methylene blue (MB) dye in an aqueous solution.

Child and Adolescent Health From 1990 to 2015: Findings From the Global Burden of Diseases, Injuries, and Risk Factors 2015 Study.

Importance: Comprehensive and timely monitoring of disease burden in all age groups, including children and adolescents, is essential for improving population health.

Objective: To quantify and describe levels and trends of mortality and nonfatal health outcomes among children and adolescents from 1990 to 2015 to provide a framework for policy discussion.

Evidence Review: Cause-specific mortality and nonfatal health outcomes were analyzed for 195 countries and territories by age group, sex, and year from 1990 to 2015 using standardized approaches for data processing and statistical modeling, with subsequent analysis of the findings to describe levels and trends across geography and time among children and adolescents 19 years or younger.

Seroprevalence, pattern and outcome of HIV/AIDS among surgical patients at Gondar University Hospital.

Background: HIV/AIDS affects not only medical but also surgical patients. Post operative outcome could be influenced in a form of increased morbidity or mortality.

Objective: To determine prevalence, pattern and out come of HIV/AIDS among surgical patients at Gondar University Hospital (GUH).
