The voltammetric behavior of captopril in presence of
copper ions was investigated by using adsorptive cathodic stripping
voltammetry at hanging mercury drop electrode.
The last stage endured on obvious erosion especially the front and the
end of the blade . The erosion caused the appearance some cracks in
this place. These remarks coincided with the theoretic al results ,
which were acquired according to the con
dition of the turbine of
station which showed that the droplet , which collided with the blade
ends, caused high pressure on the surface of the blade and caused
the occurrence of the corrosion . The danger of the erosion
unavoidable due to its relationship with tae station efficiency and the
only to avoid that is the use of the blade made of erosion resistance
ingots .
The importance of this scientific research stems from the increasing demand for
building materials, especially the materials involved in concrete industry. The attention
was directed towards finding alternative locations for primary oresin addition
to the
process of reconstructing old mines as the continues inequitable taking of these materials
will eventually result in wasting those resources losing them before using them in an
economical suitable way. We have defined the hope positions in the areas of Banias and
Tartous. We can say that deterioration of volcanic products in those areaswas a direct
result of suitable climatic circumstances which were predominant (weathering process,
deterioration, physical erosion, and chemical like wetness, wind, rain, temperature, and
surface water streaming). The tectonic which attacked those formations later served to
boost the weathering and erosion degree so that it became more effective for the
production of some oxides such as (calcium oxide, iron oxide, aluminum oxide,
deterioration of rock components, and concentration of clay) asplain strataof clay
deterioration according to geochemical analyses conducted in this research.
The Syrian steppe occupies an area of about ١٠ millions hectares
representing ٥٥٪ of the country. Due to the relatively high rainfall averages the
steppe is known as one of the best grazing areas in the Arab World. This
picture however has been ch
anged in the recent decades due to the expansion of
rainfed barley cultivation and consequent destruction of the natural shrubby
cover by tillage.
Other reasons leading to land degradation is the steppe overgrazing and
shrub cutting for fuel . High soil erodibility is caused by the week structure and
light texture of the soils of the steppe. As a result wind erosion became a
prevailing process in the steppe. This phenomenon was remarkably accelerated
during the last decade.
Dust, dust storm, sand accumulation on roads, railroads, villages houses,
formation of sand sheets with different thickness and sand hummocks around
shrubs were the main environmental features consequences.
