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 this 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.

Critical review
دراسة نقدية: البحث قدم مساهمة مهمة في مجال دراسة الخصائص الفيزيائية للخيوط، إلا أنه يمكن تحسينه من خلال توسيع نطاق العينات المستخدمة لتشمل أنواع مختلفة من الخيوط وليس فقط القطنية. كما أن الاعتماد على عدد محدود من الاختبارات قد لا يعطي صورة كاملة عن جودة الخيوط. يمكن أيضاً تحسين البحث من خلال استخدام تقنيات تحليل بيانات أكثر تطوراً وتقديم تحليل إحصائي أكثر تفصيلاً. بالإضافة إلى ذلك، قد يكون من المفيد تضمين دراسة مقارنة مع نتائج أبحاث سابقة في نفس المجال لتعزيز موثوقية النتائج.

The study was carried out at Soil Research Center in the province of Daraa during 2011 in order to study some physical and moisture characteristics for cinnamon soil, which occupies (48000 km²), equivalent to 26% of the area of the Syrian Arab Rep ublic and represents the cultivation of growing field crops with a rainfall ranges between 150- 300 mm. The results showed that the mechanical analysis for soil referred that its texture is clay with a good ability to retain water, the field capacity rated between (30-38.85)%. The studied soil has high value of available water (38.93mm) and useful water (25.69mm) in the surface layer. The highest value of permanent wilting point and hygroscopic moisture was reached in the final depth in studied profile soil, It was also distinguished a high total porosity ranged between 51.78 and 55.59% with a good air porosity amounted to 9.38 - 15.47 % in different depths and with the decline to 5.51 % in the depth 30 - 45cm.
foamed concrete is a concrete made by cement slurry mixed with foaming agent, so that foamed concrete is lighter than conventional concrete. The objectives of this study is to produce this kind of concrete, and to study some of its physical and mec hanical properties. Mix design of concrete was made for four required densities (1000, 1300,1600,1900 kg/m3), cement content of 350 kg/ m3, and water to cement ratio equal to 0.5. Different tests were performed to determine some properties of product concrete such as density, compressive strength and splitting tensile strength. The results demonstrated the possibility of production foamed concrete with wide range of density and strength. The oven dry density of foamed concrete was in the range of (870-1773 kg/m3) , compressive strength was in the range of (2.95-16.2 Mpa ), and the splitting strength was in the range of (0.32-1.76Mpa).
Palaeomagnetism and some magnetic and physical properties (magnetic susceptibility, intensity of the Natural Remnant Magnetization (NRM), ac current electrical conductivity and density) of 136 samples from 22 sites of the Yemen Volcanic Group TKY (Tertiary and (or) Cretaceous) from igneous rock exposures along the road from Sana’a – west towards Al-Hudyadah were studied. A single population consists of seven Virtual Geomagnetic Poles (VGP), of the Upper Oligocene, was accepted and a mean at 182.81° E, 77.44° N with α95= 12.5° was calculated. The different properties were measured in order to use these properties as characteristic factors to discriminate the neighboring igneous flows. The measurement of the in situ magnetic susceptibility of 140 points, distributed on 7 sub-areas, in the region helped to calculate the mean value of the magnetic susceptibility of each sub-area, which might be used in any magnetic interpretation of aeromagnetic or magnetic anomalies. Also, the density of 132 samples were measured and a mean value of the density of each sub-area was calculated in order to be used in any future interpretation of any gravity anomaly in the area.
This study was conducted during the 2011-2012 and 2012-2013 seasons in Abu-Jarash orchards area in Damascus to identify the effect of improved organic materials as sludge, manure and compost in improving some soil physical characteristics and whea t productivity. Results showed that the three types of organic material affected the physical characteristics of the studied soil. They decreased its bulk density, increased its total porosity and increased its ability of holding water at field capacity. Results also showed that the compost of city wastes was the best in improving soil physical properties. The three organic materials, particularly the sludge increased the total productivity of wheat (Sham3).
Some magnetic and physical properties ( magnetic susceptibility , intensity of remanent magnetisation , ac current electrical conductivity and density ) of ١٨١ samples from ٣٠ sites of Middle Miocene basaltic rocks (β 1 N2) from Al- Kisweh region south of Damascus were studied, in order to extend the previous study ( Abou-Deeb, ١٩٩٧) to other regions so that these properties might be used as characteristic factors in discriminating the neighbouring basaltic flows .The measurement of the in situ magnetic susceptibility of ٧٥ basaltic sites , distributed on ٨ localities , in the region helped to calculate the mean value of the magnetic susceptibility of each locality and an overall mean value of the whole region, which might be used in any magnetic interpretation of the magnetic anomalies. Also, the density of ١٢٨ samples were measured and a mean value of the density of each locality and an overall mean density were calculated in order to be used in any future interpretation of any gravity anomaly in the region .
