Net radiation plays an essential role in determining the thermal conditions of the Earth’s surface
and is an important parameter for the study of land-surface processes and global climate change.
The estimated monthly ...
The ionosphere causes delay of radio signals, and if not mitigated, it can be the
largest source of error in GNSS positioning and navigation. The ionospheric models
can be used to estimate these ionospheric errors and ...
Abstract
The height profile of atmospheric temperature data between 12 km and 100 km was obtained from
SABER satellite instruments during the year 2016 and used to characterize the temporal variability of
height and ...
This thesis presents the effect of using computer simulations instead of laboratory equipment as teaching aids. The research was carried out at Tana Haik Secondary and preparatory School on grade 12A and 12B students who ...

Stimuli-polymer brushes are found all over the world around us in different forms and show progressive changes from the 15th century to the 21st century.Especially, thermo-responsive polymer brushes(PNIPAM) have so many ...
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 sufficient ...
ABSTRACT
