This study is devoted to the durability of bituminous mixtures,
including the effects of different gradations, compaction
temperatures and immersion time on the durability potential of
mixtures.
During the season of 2002, samples of olive fruit were taken (Ashrasi type)
from Ninavah horticulture’s station that belongs to the ministry of agriculture
in Iraq. The purpose of this research is to study some physical and chemical
characteristic
s during the growing period, from July until October. Those
characteristics include moisture, ash, oil content, chlorophyll A & B, protein,
pH and carbohydrate, In addition to fruit length, size, weight, radius, and
rigidity. The results showed significant increase in moisture, oil, weight, size
and length of the fruit were studied. Significant reduction was noticed in the
percentages of the protein, carbohydrate, ash and the fruit rigidity. The highest
values of chlorophyll were observed during The month of September. October
considered as the best time to harvest olive fruits for pickle purpose.
The research aims to study the effect of the distribution water on
Proton Exchange membrane fuel cell (PEMFC), and the
relationship of membrane thickness and the effects of changes in
thickness depending on the amount of water contained within the
membrane. The research also aims to change the effect of humidity
on the effectiveness of the membrane proton through the diffusion
coefficient and the coefficient of the flow electral osmotic. The
research includes the study of humidity on the cell performance at
constant temperature and its effect on the input interface.
Physical properties of soil in terms of calculating the gravitational water percentage, calculating moisture in the soil, and calculating porosity by calculating the apparent and true density.
