نظراً لأهمية البرك الشمسية الاقتصادية في التطبيقات العملية اليومية المنزلية و الصناعية, و انتشارها الواسع في العالم, فقد شكل ذلك أساساً للقيام بدراسة تجريبية على بركة شمسية موشورية الشكل مطلية من الداخل باللون الأسود مساحتها السطحية (1m2) و السفلية (0.42 m2) بعمق 1mأيضاً, مؤلفة من أربع طبقات متدرجة الملوحة تفصلها عن بعضها البعض ألواح زجاجية شفافة /زجاج منزلي/ سماكة (6 mm), وضع في الطبقة السفلية منها جسم صلب أسود اللون (عبارة عن حجارة بركانية سوداء اللون بأبعاد متساوية 1Cm تقريباً).و بدراسة درجات الحرارة و كذلك الكميات الحرارية المخزنة بتابعية الزمن لمدة ثماني ساعات يومياً من 9 صباحاً و حتى 5عصراً, تبين أن المعدلات الوسطية لكمية الحرارة المخزنة في كل ساعة و المحسوبة وفق العلاقة (Q = m.Cp.ΔT) خلال ستة أشهر (من شباط و لغاية تموز2016 م) تبلغ: 9962.445KJ, 9516.28 KJ, 10783.471KJ, 9765.836KJ, 14010.393 KJ, 12164.320 KJ على التوالي.
According to the importance of economic solar ponds in domestic and industrial daily practical applications and its international widespread, this created the basis of an experimental study on a prismatic solar pond. It is internally painted in black with a surface measurement of (1m2) and a lower measurement of (0.42m2) and 1m deep. It constitutes four levels of gradual salinity separated by transparent glassy tablets /home glass/ of (6mm) thickness. On its lower level, a black solid mass is placed (black volcanic stones of equal dimensions; almost around 1cm). Upon studying the temperature and the stored thermal amounts of via subsidiary time every day from 9 am until 5 pm, the average rate of stored thermal amount each hour calculated according to the following equation: (Q = m.Cp.ΔT) during six months (February until July 2016) was: 9962.445 KJ, 9516.28 KJ, 10783.471 KJ, 9765.836 KJ, 14010.393 KJ, 12164.320 KJ respectively.

Water erosion is considered one of the most prominent and dangerous forms of soil erosion, especially in the coastal region, where it rains in large quantities. Consequently, this results in sweeping away tons of soil into the river streams; some of
this will be deposited in the rivers, some in the dam lakes constructed on these rivers, while the rest will be deposited in the sea into which rivers flow. The aims of this study are to calculate the ratio between the amount of sediments related to water erosion of the soil and the amount of the sediments transported in Zgaro River which reach the lake of 16 Tishreen Dam, and to suggest the appropriate solutions which will insure reducing the sedimentation rate and its correlated negative impacts. This study demonstrates the characteristics of the watershed of Zgaro River using Watershed Modeling System (WMS 7.1), and also the calculation of the total amount of sediments related to water erosion of the soil in the area of study, applying the Universal Soil Loss Equation (USLE). The amount of sediments transported by water was also calculated using internationally recognized measuring devices. These devices were manufactured for the purpose of this study. A total of 24886 tons of transported sediments was measured in Zgaro River, constituting 36% of the total annual amount of 69401 tons of sediments resulting from water erosion of the soil. This value comprises the actual amount of sediments deposited in the lake of 16 Tishreen Dam, which is then transported through the river stream. Consequently, this sedimentation has resulted in a downward trend of the reservoir capacity of the dam lake. These findings require feasible solutions to reducing the rate of sedimentation and its correlated negative impacts.
The disposal of solid waste is one of the most important contemporary environmental issues. Increasing population and what has been associated with the change in the patterns and lifestyles and increased consumption led to increasing the amount of pr
oduced waste and its quality, especially in cities; the estimated amount of solid waste produced daily in the city of Latakia was 840 tons. Thus, there is an urgent need to follow the techniques in the management of solid waste in all stages to maintain human health and protect the environment from pollution.
This study as a whole aims to estimate the amount and characteristics of solid waste, the methods used to collect and analyze the spatial distribution of the current waste collection containers in areas of the city of Latakia, better planning commensurate with its population and the amount of waste produced using GIS technology. To accomplish this, we have a comprehensive field survey to collect the waste containers in the study area where they were monitoring their locations and identifying characteristics; we relied on statistical analytical approach in the recruitment of data that have been obtained, and used the map to the city of Latakia Tags. And, through the program (ARC GIS 9.3) the data has been entered and processed, linked and analyzed using analysis tools attached to the program, exit maps and various forms that serve the study.
The study concludes that the current number of containers is not enough when discharged per day, and that the spatial distribution is not commensurate with the amount of waste produced in areas of the city .
Researchers and scientists to ease due to electric power generation
using fossil fuel plants with environmental pollution is seeking, in the
discovery and improve the methods of generation using renewable
energies. Floating solar chimney technolog
y of the most promising
technologies that can be used in power stations with solar chimney is
considered.
The research aims to give results on a proposal to determine the
specifications for the plant of this kind in the climate of the city of Homs,
for example, and the study of the behavior of this station and analyze the
most important parameters affecting it. In this research study hydrothermal
behavior floating solar chimney in the climate of the city of
Homs by a program written in a language programming EES thermal
power station.
In this research a study effect of absorbed surface shape for solar air collector
(Flat V-Corrugated ,Sinusoidal Wave-Corrugated ,Rectangular-Corrugated) titled to the horizontal by an angle(30) on forced heat transfer and skin friction coefficient
by Fluent Numerical Program at constant solar heat flax (530W/m2) with Reynold’s number (5000≤Re≤8000). The government equation (mass, momentum and energy) are using Finite Volume by (Fluent 6.3) software for considering steady state, two dimensional and turbulent flow. The results show that the different between inlet and outlet air temperature is(13.65oC) and best heat transfer coefficient enhancement is(63%) for (V-Corrugated plate) compared with the flat plate at (Re=8000). Also the results show that the maximum skin friction coefficient is occurred at (V-Corrugated) Cf=0.22 at (Re=8000).
The objectives of this research were to study the effect of moisture content
and temperature of corn stored in where-houses and out-doors for production
and determination of Aflatoxin B1 in Syria.
200 tons of corn crops was used for our experiment
, and was divided 100
tons each for storage out-doors and in-doors respectively according to General
