يعتبر التوافق بين الآلات الزراعية و المواد التي تتعامل معها من المتطلبات الأساسية التي تحقق أفضل أداء للآلة، و لتحقيق هذا الهدف يجب توفر بيانات و تحليلات دقيقة عن الخواص الهندسية لتلك المواد، و التي تشكل قاعدة بيانات ضرورية في تصميم و تطوير و تركيب الآلات و المعدات الزراعية و في التحكم في هذه الآلات، و في تحليل و تقدير كفاءة عملها. و قد أجري هذا البحث لدراسة بعض تلك الخواص الفيزيائية لبذور بعض المحاصيل الزراعية السورية الشائعة، من ثم استخدام بعضاً من هذه الخواص في تحديد و اختيار أجهزة التلقيم في آلات البذار و التسطير، و التي تتوافق مع بذور تلك المحاصيل المحلية. و قد تم دراسة هذه الخواص لتحديد أشكال و أبعاد خلايا أجهزة التلقيم في آلات البذار المناسبة لزراعة كل من: الذرة الصفراء، البازلاء، الحمص، الفاصولياء، الفول، و أخيراً القطن، و كذلك تحديد أبعاد تموجات جهاز التلقيم ذو الأسطوانة المموجة في آلات التسطير لزراعة كل من: القمح و العدس، بالإضافة إلى ذلك تم وضع مجموعة من المعادلات يمكن من خلالها معرفة الخواص الهندسية للبذور المدروسة من خلال معرفة أحد أبعادها الثلاثية فقط.
A proper matching of agricultural machinery with properties of materials forms the essential requirements which lead to best performance of machine. To achieve that goal, availability of data and precision analysis on engineering and physical properties of these materials is required. This forms important and necessary data base for the design, development and structure of agricultural machinery and equipments, control and analysis of machines and determination of efficiency of machines. This research was carried out to study some engineering and physical properties of seeds of common Syrian crops to be used in the design and development of some agricultural machinery and equipments. Results provided the shapes and dimensions of cells of feeding devices for planting seeds of some crops namely, wheat, maize, lentil, pea, chick-pea, kidney bean, broad bean and cotton. In addition a set of empirical equations were established to be used to predict, with reasonable accuracy, the physical properties of crops seeds based on measurement of any of three dimensions (length, width and thickness).

The phenomenon of impact between the adjacent buildings is one of the most important reasons for collapse of buildings during the
earthquakes for that most of the codes resort to avoid impact by
increasing the distance between adjacent buildings, b
ut on the other hand high cost of land requires us to take advantage of the largest possible area in addition to the difficulty of making the separation architecturally and in particularly for high buildings the separation may offer up to 50 cm.
We tried to have this research one of the studies that discuss the
subject of seismic pounding where we discussed the methods for
modeling the pounding and the most appropriate way to study the impact depending on the program dynamic analysis Ansys
(Autodyn Ver. 11) then chose several cases for study seismic
impact in three-dimensional models to cover most of the study
variables that may affect this phenomenon, and we doer non- linear dynamic analysis for all cases, with applying acceleration function is defined by equation its constants are changing with processing the seismic records data.
After finishing the analysis for all the models we have discussed
changing the transitions and stresses and strains , and studied the
factors affecting the impact , and discussed results of study and
then we have summarizes the recommendations in that we see fit
through this search.
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).
In this work, several samples of poly(propylene itaconat ortho
phthalate) based on itaconic acid and 1,2-propylene glycol were
prepared by polycondensation.
He studied the effect of conservative and traditional agriculture on some different soil properties by digging soil sections in five fields belonging to the Agricultural Scientific Research Center in Salamiyah, the General Authority for Scientific Agricultural Research during the 2015 and 2016 seasons.
The effect of clay soil treatment with two levels of tobacco west compost and
organic fertilizer (15 and 30 ton/ h), in addition to mineral fertilizer treatment, with three
replicates of each treatment on some physical properties (Aggregate size di
stribution, main
weight diameter, bulk density and porosity) and chemical properties (Organic carbon,
humic and volvic acid and humification index for big and small soil aggregates was
studied.
The results showed that tobacco west compost and organic fertilizer were effective in
increment of soil content of organic carbon, which reached (20 and 26%) for organic
fertilizer, and (39 and 45%) for compost compared to the control, conducing to ameliorate
soil physical properties, where The main weight diameter, stable aggregate rate and soil
porosity were increased. Whereas, bulk density decreased significantly in both treatments
compared to the control. Compost treatment affect soil physical properties more than
organic fertilizer.Mineral fertilizer decreased soil content of organic carbon compared to
the control.
Humic and volvic acids contents were between 2.12 and 74.3 mg/kg aggregates in
the control,and compost treatments alternatively in macro aggregates (> 2mm). Wile,
volvic acid values were between 0.93 mg/kg in control for small aggregates (< 0.25), and
3.17 mg/kg aggregates in mineral fertilizer treatment for (0.25 – 2) aggregates.
Humification index values were less than 2 in macro aggregates, while it was bigger than 2
in small aggregates.
