High temperature superconductivity is a remarkable phenomenon in which certain materials
conduct electricity with zero electrical resistance and expel an internal magnetic field at
temperatures higher than 30 K. Bednorz ...
Post-sunset ionospheric irregularities are common features of the equatorial ionosphere
that affect radio communication and navigation systems. It is known that these irregular ities have shown longitudinal and temporal ...
Climate change and weather dynamic is the cross-cutting issue all over the world.
For developing countries, especially, for East Saharan African countries including
Ethiopia, the backbone of the economy depends on ...
Graphical knowledge, core component of the science curriculum, is an essential skill for
any technological innovation. A lack of such a skill is a reflection of poor conceptual
understanding. To assess students’ ...
The main task of this research is to enhance the gain of a two stage CMOS operational
ampli er by using current bu er technique It involves three basic concepts,
theoretical calculation, design, simulation, and veri ...
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 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 ...

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. ...
