This study aimed to find, build and contribute a sustainable economic battery material. The
researcher investigated the effect of replacing a glass former that is either of the same size or
larger than the main glass ...
The current research work deals with the theoretical study of the interplay between superconductivity
and ferromagnetism in iron based high temperature superconductor

The ionosphere, also known as the ionized part of the upper atmosphere, is believed
to vary as a function of di erent parameters such as solar and geomagnetic activities.
One of the peculiar parameters that describes the ...
Heat wave is the period of abnormally an increase in average temperatures for at
least three consecutive days which can leads to dangerous, even deadly, health consequences,
including heat stress and heatstroke. Heat ...
In this paper, we present the responses of the ionospheric total electron content (TEC) to coronal
mass ejection (CME), and co-rotating interaction region (CIR) driven storms using stations that
lie 37

Precipitation over the Upper Blue Nile Basin (UBNB) contributes most of
the annual rainfall in Ethiopia and plays an important role in agriculture and
thus the economy. In this study we applied various wavelet analysis ...
Light, as any other electromagnetic wave, always propagates as a transverse wave, with both
electric and magnetic fields oscillating perpendicularly to the direction of propagation. The di rection of the electric field ...
The main task of this research is to design and simulate single-ended output folded
cascode CMOS op amp by using OrCAD PSPICE Design and Simulation software
based on analog and digital electronic devices and advanced ...

Low power operational amplifier with a rail-to-rail voltage design has become an
increasingly interesting subject as many applications switch to portable battery powered operations. The need for design techniques to allow ...
Due to the problem associated with device power dissipation, the demand for low
power devices is increasing at a faster rate as a result of wider implementation of
smaller-sized, portable, and hand held devices in the ...
Chirality is at the origin of life and existing in nature. A system is named chiral if it is nonsuperimposable
with its own mirror image. Such object interacts with left and right circularly
polarized lights differently. ...
Atmospheric variables like precipitation, stream flow are significantly influenced by various climatic
factors and large-scale atmospheric circulation patterns. Investigations for the variation
of rainfall by different ...
Mesospheric temperature inversion layer (MIL) refers to the positive temperature gradient inversion that is typically detected as a thermal structure in the mesosphere and lower thermosphere at lower and middle latitudes. ...

Upper Blue Nile Basin (UBNB) is the water tower of not only for Ethiopia but also for
downstream countries. This region is quite useful for agricultural purposes, owing to essential
climate elements such as ...
ABSTRACT
This research work focuses on the theoretical investigation of the upper critical magnetic field,
𝐻𝐶2 for superconductor SrFe2-xCoxAs2. In this research work, we used the Ginzburg-Landau
phenomenological ...
Aerosols are minute liquid or solid particles suspended in the atmosphere. Aerosol optical Depth
(AOD) and Angstrom Exponent (AE) are significant parameters to study the concentration and
size or type of aerosol over an ...
Climate change and variability is posing adverse impacts on the economic, social and political livelihoods of mankind. The main objective of this study is to examine the impacts of climate change and variability on agriculture ...
Scintillations are the effect of irregular electron density on the propagation of electromagnetic
signals through the ionosphere. The scintillating signals change phase unexpectedly and vary
rapidlyinamplitude. ...
