In this paper, we discussed the motion of charged particles in the external fields and the
radiation of a system of two action reciprocal charges. Where we find that the motion of
each charged particle, or precisely the motion of the moving charged
particles in orbits has
conical forms, and their foci are located in the center of inertia, and this is compatible with
Kepler's problem in determining the motion of the planets.
As we have shown, the results obtained are that a system consisting of two identical
particles, or of different particles, with the same ratio (e / m) , can not radiate in a dipole
approximation, and that the moving charge in a closed orbit continuously radiates energy.
The differential cross section of particles scattering was calculated according to the
Coulomb law, and the radiation value resulting from the incident of a beam of charged
particles was finally calculated on a static charge (the braking radiation), where the
radiation energy was found to be inversely proportional to the particle velocity as well as
the cube with the radius of the radiation correction, and it is associated with the angle of
scattering and the azimuth angle.
Studying the mechanics of particle systems in special relativity is one of the most
complex issues. However, this study sets us up to lay the groundwork for building a set of
important laws. The motion of particle masses as a whole was determined b
y their energy,
impulse and static mass. It was also found that the total energy of the system of mutual
action requires taking into account the energies of these mutual acts between the particles.
Contrary to the systems of the mutual acts of collisions, approximate formulas for
interplay between charged particles were determined by studying the collision of
relativistic particles-Compton's effect.
Finally, the case of the movement of the charged particles of weak interacts was
discussed, and the movement of the interconnected particles was discussed through mutual
electromagnetic acts using the concept of mutual action between the particles of the
system.
The research aims to estimate the marketing efficiency of rain-fed cumin crop in Malikya
area (Al-Hassaka governorate),this in order to reach the estimation of the total costs of marketing
functions, medium and marginal costs, and estimate the econ
omic volumes of marketed quantities
of cumin. This study main problem lies in the search for high marketing costs of latency. Find
carried out based on cross-sectional data, that were collected from a random sample of some cumin
farmers and traders in Malikya area (88 farmers from 24 villages, and 12 trader cumin), And
adopted in the implementation of research analysis method rebound with a single equation, to
explain the relationship between marketed quantities of cumin as an independent variable, and the
value of its marketing costs as the dependent variable. Results of the analysis showed that the value
of the coefficient of determination (R Square) amounted to 0.841, and this means that the quantity
of marketed cumin explain 84.1% of the changes in the marketing costs of cumin, The results of
econometric analysis also showed the presence of deviations between marketed quantities of
cumin, and the size of optimal marketed quantities due to higher overall marketing costs, medium
costs, and marginal costs for the quantities marketed, means increased current cost of marketing for
one kilogram of cumin, from those achieved for marketing efficient g by (2.1) SP / kg,
furthermore, the application results of equations, measuring marketing efficiency (which relied on
total production costs, the current cost of marketing the crop cumin, and the selling price per
kilogram of it) showed that, the value of marketing efficiency amounted to about 88.29% and
50.53% depending on the indices marketing efficiency (equations 1 and 2 ) respectively , While the
value of marketing efficiency (which relied on total production costs, and the optimum marking
cost of the cumin, and the selling price per kilogram of it), about 90.54% and 52.73% depending on
the indices marketing efficiency (equations 1 and 2), respectively, The research found a set of
recommendations, such as establishing a marketing institution that oversees the operations of sale
and marketing of medicinal and aromatic plants Group, and market surveillance in order to prevent
monopoly, and improve the performance of marketing functions that traders provide when
marketing of medicinal and aromatic products that, in order to reduce the costs of marketing, and
delivery to consumers at the best prices.
A research was conducted in the northern and western area of Homs province
using four methods of tillage namely; Surface Disk ploughing, Turning Ploughing,
Standard Disk Ploughing, and Chisel
Ploughing. The prepared soil resulted of this research was planted
with cumin) Cuminum cyminum L.).
The identification of the cumin oil composition was determined
qualitatively and quantitatively by GC, using standard compounds.
The components of the cumin seed oil (Cuminaldehyde, p-cymen
and β-penine) were matched with the standard compounds.
The factors effect on some components of cumin seed volatile oil
were studied.
The effects of time and temperature on the cumin seeds
components were studied, the results have been shown that the total
oil and volatile oil and its main components decreases with the
passing of time and with the increasing of temperature.
This study was carried out during the growing season of 2015
to study effect od three planting date (1 Feb., 15 Feb. and 1
March) and four levels of nitrogen fertilization (0, 40, 60 and 80
kg/Ha) with interactive effect between them on some yield
components of cumin.
According to the method VMA Based on the direct

The seeds of Syrian cumin and Brown mustard used for human
nutrition were analyzed in this study to determine some of their
major chemical constituents and minerals.
The results showed that the contents of cumin and mustard seeds
were protein , l
ipids,
phospholipids , ash respectively.
Mineral contents were phosphorus, ,calcium , Magnesium , potassium , and iron for cumin and
mustard seeds respectively.
The purpose of this research is to design and realization of an electronic apparatus which is able to control the process of irrigation that depending on soil moisture .This apparatus organize the process of irrigation, when the level of soil moistur
e under a specific value that it was chosen depending on water field capacity of crop ,it operates the pump which connected with it, and when the moisture level reaches that value the pump stops working.
The apparatus consists of two parts:
The first part: An electronic circuit using a number of operational amplifiers ,some electronic elements ,and voltmeter to measure voltage between load resistance which is in serial with resistance between two probes that set in soil.
The second part: An electrical part ,which provides a secure connection between the previous electronic circuit and water pump.
This study was carried out on a simple of black soil .The relation between electrical resistance of soil and volume of water used in irrigation was drawing for three values of distance between probes and power supply. We found an intense declination curves for small values of used water volume.
In this research, the electrochemical reduction of hydrogen process
and the factors affecting the reduction potential have been studied
in this research. The effect of acid concentration on the shifting of
the volt-ampero-metric curves that expres
s the reduction process
and so its effect on both the reduction potential value of hydronium
ions on drop mercury electrode, and the speed value of reduction
reaction was studied. Then an amount of pyridine as organic
substance was added to a specific volume of acid in a specific
concentration to figure out the relationship between the amount of
pyridine added and the cathode current of the reaction to find out
the effect of added pyridine on the reaction speed and the
relationship between the amount of added pyridine and the
hydrogen reduction potential.
Pyridine was added to amount of acid to study the effect of
theaddition on the hydrogen reduction over potential.
