We have done many counts, strength and twist tests - which are considered the most important physical properties that determine yarns quality specification - on cotton yarns at the industrial researches& tests center. The researcher has depended on t
his tests results to find out formulas which match between physical properties of yarns, starting from common formulas then he has proved them by analysis of results that we got from graphic tests instruments, then we have figured out proportion constants between these physical properties from curves that we have got by tests results exemplification and we have shown if these constants describe common constants or new constants.
A lubricant (Lithium-Sodium) of Syrian petroleum-based stocks and
thickener material depends in its preparation on Skinless chicken fat, was
manufactured at different ratios.
A study of physical - chemical properties of manufactured grease types w
as
carried out (compared with Syrian standard specification 791/2008) by using
standard methods which included: grease state, penetration degree, drop point,
free acidity (as oleic acid)% by weight, grease resistence to water, evaporating
at 90° C, and corrosion of copper plate. Where the results show that the best
type of grease is of 30% ratio.
The physical properties of gravel play an important role on the
quality of concrete industry in local workshops. Because they
constitute a main role in various concrete mix design. It's
necessary to understand the importance of the physical proper
ties
of gravel and It's improving role in the concrete mixes.
This research aimed to study the role of the properties of gravel
on the concrete mixes manufacture.
This paper presents an experimental study to determine the physical and
some other important properties of certain waste materials, in order to
identify the appropriate field of their recycling. The experiments have
been carried out using five proposed materials, namely: corn cob, peanut
peel, straw, pine cone, and sticks of the stem Thistle Syrian plants.
Carob pod is the fruit of the carob tree (Ceratonia siliqua L.). The
fruit and its products, sold both in large stores and local markets,
contribute strongly to the diet of people living in the Mediterranean areas
of Europe.
This study reports th
e composition of carob pods sampled in
Homs, Hama and Coast Regions
This research was conducted in 2016c, at the Zahid Western
Research Station in Akkar Plain region of Tartous Governorate, the
objective of this research is study the effect of non-conventional
organic waste (compost of garbage, sewage sludge) and
cow
manure on the physical properties of clay soil in the region. Wastes
was added to the soil at a rate of (0 - 10 - 20 – 30) t/ha, in order to
determine the effect of the difference in the quantity added on
physical properties of the soil and peanut productivity.
