This research aims to study the sterols which is considered, one of the most
important minor compounds, and characterizes vegetable oils.Ten items were
selected from the planted seeds of safflower in Syria in the spring of 2010.
Oil was separated
from seed oil extraction with petroleum ether, then the
content and content of the sterols were specified by using gas chromatography
according to the standard method in the appointment of sterols in olive oil. The
study concluded characterize safflower seed oil sterols from their content,
Sweeteners are used as alternatives of Sugar because of their slow
absorption and incomplete metabolism in human body, which are positively
destinies in setting free small amount of calorie.
This research presents the influence of ultrasonic on th
e sorbitol synthesis,
starting from Glucose by implementing hydrogenation using Lithium
Aluminum Hydride. The result we have reached by using the ultrasonic as
compared with mechanical mixing or other method have lead us to two
conclusions:
The first was that we have obtained almost the same quantity of the sorbitol.
The second was that by using ultrasonic, micelles of colloid Aluminum
hydroxide were accumulated. This accumulation resulted in an easy separation
by purification, which eventually lead to a super pure sorbitol solution.
We hope that these results will be useful for the Crystallography science.
This research focuses on an environmental and economic aspect, as it depends on using the harmful water hyacinth weed as an effective material to product the biopolymer "polyhydroxybutyrate: PHB" by Bacillus subtilis. The samples were processed and d
igested to extract the polymer polyhydroxybutyrate (PHB) using chloroform method. Some tests were carried out to confirm the identity of this polymer, such as measuring the melting point of the product and studying the functional groups of the extracted PHB using the Fourier-transform infrared spectroscopy (FTIR). The results obtained by the extracted polymer from the water hyacinth weed showed conformity to the referential PHB polymer tests, which shows the importance of this research in determining a way to get rid of this harmful weed, which is an environmental problem and a large economic burden by investing it in the production of biopolymer PHB.
In this article, a polyester amide was synthesized from oleic acid. This polymer is a biodegradable and thermoplastic polymer, with wide medical and biological applications due to its being compounds with a linear structure. The polymer structure has
been confirmed. Output using spectroscopy methods known as 1H-NMR, and FT-IR spectroscopy. And we obtained this polymer with a good yield (78%).
This research deals with analytical study of exterior Beam-Column
connections behavior under seismic load.
Tow parameters were considered: axial load on the column and
confinement of joint region with stirrups.
Ansys program was used to analytica
l study of three types of exterior
Beam-Column connections under cyclic load.
The results were shown a good agreement with general behavior of
three types.
The analytical results indicate that the tow parameters will improve
the behavior of the connections delay cracking at joint core and
increasing connection stiffness in rotation and displacement with
decreasing shear value at joint.
