In Ethiopia 60-80 of the population suffers from water –borne and water related diseases due to
lack of safe drinking water distribution. The aim of this study was to determine the physico chemical quality of drinking ...
Nanocomposite materials based on metal nanoparticles and graphene oxide (GO) have gained
increasing attention for their wide range of potential applications in various material science fields.
In this study, GO ...
This study was conducted to analyze the major phytochemicals to evaluate the antioxidant
capacities by using, 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activities)as well as to
determine the total phenolic, ...
Heavy metals such as lead and cadmium are toxic to environment even in very small
concentration. Thus, a sensitive and selective sensor is required to determine such a very low
concentration. The purpose this work was ...
In this study three Iron(III) complexes with resorcinol and 2,2’-biphyridine, [Fe(RH)2(H2O)4]Cl
(1),[Fe(HR)2(H2O)2Bpy]Cl (2), and [Fe(RH)2(Bpy)2]Cl (3), where synthesized and characterized.
The complexes where synthesized ...
Solar irradiance model can reduce the uncertainty of solar power plant output caused by solar
irradiance intermittency. In this study, multiple linear regression (MLR) and artificial neural
network (ANN) methods were ...
Background: The high population of youth unemployment is one of the most critical issues at the
global level. Which is caused by socio-economic and demographic factors. Exploring the spatial
distribution and identifying ...
There are over two hundred traits that are transmitted from generation to generation in humans,
which is an interesting aspect of human genetics and known as hereditary traits. This genetic
variation can be caused by ...
Studying primate population parameter and human primate interaction is important for planning
conservation management actions. Human wildlife conflict is any form of interaction that results
direct or indirect cost to ...
The design of op-amps continues to pose a challenge as the supply voltage and transistor
channel lengths scale down with each generation of CMOS technologies. In this
thesis, a single stage telescopic CMOS op-amp is ...
In particular, the East Gojjam and West Gojjam zones of the Amhara region are heavily planted
for coffee Arabica. However, the national and international markets have not been adequately
described or marketed for this ...
In this work, three ruthenium(III) complexes ([Ru(bpy)2Cl2]Cl, [Ru(bpy)2(HR)2]Cl and
[Ru2TA]Cl6 were synthesized from 2,2’-bpy, resorcinolate (HR) and tannic acid. The synthesis
was checked using qualitative and ...
Ionospheric irregularities and GPS LoL can affect a wide range of communication and nav igation systems, thus studying and analyzing them using GPS data near the equator and at
low latitudes is justified for both scientific ...
Soil transmitted helminthes (STHs) are parasitic worms that infect humans and spread via oval or
larvae-contaminated soil. In order to become infectious, some parasites' immature or
undeveloped life-cycle stages (eggs) ...
COVID -19 infections are a serious problem in the world, Africa, Ethiopia, and Amhara region.
ABO blood types play a significant role in various illnesses like oncological, cardiovascular, and
certain infectious and ...
Intestinal parasitic infections are major health problems in many developing countries, particularly
among pre-school and school-aged children. The current study aimed to determine the prevalence
and associated risk ...
Soil-transmitted helminth infections (STHIs) are caused by different species of parasitic worms
and transmitted by eggs present in human feces which contaminate the soil. They are common
among school-aged children. ...
In this project work, we have investigate the effect of size variation of amorphous silicon quantum
dot(a-SiQDs) on intensity of thrermoluminescence(TL)emission using interactive multi trap
system (IMTs)and OTOR model. ...
The aim of this project is to study Duhamel's principle for solving one dimensional evolution
equations (heat and wave). First, find the formula in which we able to obtain its solution we
derived by using the D' ...
In this thesis, we investigated the formation process of self-assembled monolayers (SAMs) of
organophosphonic acids on ZnO surfaces. There was the effect of solvent on the coverage of
ODPA SAM on zinc oxide surface. ...
