The Effect of Different Doses of Gamma Rays on Growth and Productivity of Local Garlic Allium sativum L. Var. Yabroudi in Syria

This research was conducted at AlTieba Research Station, General Commission for Scientific Agricultural Research (GCSAR) in 2012 and 2013 seasons, to study the effect of different doses of gamma rays on growth and productivity of local garlic Allium sativum L. cultivar “Yabroudi” in Syria. Cloves were exposed to four different doses of gamma rays of 60Co source 1, 2.5 ,5 ,10 ) Gray). Randomized Complete Block Design (RCBD) was used .The results showed the surviving plants after 60 days of planting declined with the increase of dose levels. The percentage of dead plants at the doses (2.5, 5 Gray) was 50 and 54 %, respectively. Also, it was possible to obtain a larger number of viable mutations. Therefore, they could be considered as close as to LD50. The dose (10 Gray) had a negative effect on the length of the cloves’ germination period, leading to the death of all the plants after 60 days of planting, this could be considered lethal dose (LD100). The response of the local garlic cultivar Yabroudi to the low-dose (1 Gray) of gamma ray was higher comparing with other doses. This is due to the positive effect of this dose (Stimulus) on the vegetative growth that was reflected on the productivity indicators. The productivity reached (4.50 kg/m2), which was significantly superior to the control (2.91 kg/ m2) and the two doses (2.5, 5 Gray), respectively (2.26, 1.60 kg/ m2).

Spectral Properties of Tinged Glasses with Silver Bromide by Porous Glasses Method

Porous glasses were produced using sheet glass cullet with added magnesium carbonate MgCO3 as foams agents .The structure of glasses tinged with silver bromide by porous glasses, was studied by UV–VIS spectroscopy,transmission of light and X-ray diffraction XRD techniques. glasses plates were obtained by impregnation of porous glasses at first with AgNO3 aqueous solution , next in the KBr aqueous solution. Then the samples was sintered at temperatures 950°C up to closing of the pores. The results of spectroscopy study have shown that the glasses tinged plates, according to XRD data, the glasses tinged contain the AgBr phase.

Influence of water to cement ratio on the attenuation of ionizing radiation and speed of Ultrasonic in ordinary concrete when change of temperatures

Five mixtures of ordinary concrete of dolomite aggregates were prepared by changing the water to cement ratio. Thirty six cubic concrete samples were prepared for every mixture.

The influence of irradiation on band gap Eg values for PVC membranes prepared by Casting method

In this paper samples of poly vinyl chloride PVC ,pure, irradiated with Gama rays, were prepared by casting method in room temperature and light, and under atmosphere pressure. It was observed from this research that irradiation made real effect on some of the studied optical properties, the irradiation increased the transmittance while the electronic transitions kind remained indirect before and after the irradiation.

Determination of the neutrino mass through the study of the energy spectrum of radiation of Strontium-90 isotope

In this work, using a scintillation detector with Strontium-90 source as a try to measure the electronic neutrino mass from a simple technique and different from what is used in this area where current techniques used are very complex and require substantial amounts. Also, detector calibration (to find the straight calibration equation), in addition to identified the maximum energy of β- particles (electrons), experimentally, by selection the channel number and then finding the energy value from the calibration equation (as a straight line). We have studied the disintegration changed energy with absorbent material which is an aluminum slices that have different thickness. We have observed the decrease in the values of the maximum energy of the electrons with increases the thickness of the slices. The energy changes with thickness as: E = f (x), (a straight line have a negative inclination). Applying Fermi 's theory and Kurie's plot allowed to find the maximum energy of disintegration electrons (1697,58 keV), this value is so close to experimental value (1653,45 keV), with dubity (2,6%) We have found that the electronic mass neutrino mass is almost to be non-existent, or we can said that the Strontium-90 disintegration does not allow to measure mass neutrino mass accurately, this is due to the high value of the disintegration energy of the Strontium- 90 isotope.

Studding of the Effect of Storage, Heat and Iron Ions on the Stability of Vitamin C in some food

In this research, the quantity of vitamin C which extracted from fresh fruits and vegetables was evaluate by using titration method with 6-2 Dichloro phenol andovinol, and studying the effect of conservation and different temperatures (30, 60, 90) °C which used in cooking on content of vitamin C for some samples. Also this search included studying of the effect of iron ions on content tomato, orange and lemon of vitamin C. The results showed that the concentration of vitamin c in studied samples: parsley, red pepper, green pepper, lemon, orange and tomato was (8, 22, 36, 144, 175, 133) mg/100g respectively. Losing of the vitamin was (66%, 65%) when we save the leaves and stalk of parsley for 24 hours respectively, when exposure the parsley leaves to the temperatures (30, 60, 90) c° the losing percentage was (24 %, 41%, 62 %), While the losing was (79%, 65%, 39%) when injected each of tomatoes, oranges, lemons with dissoluble of iron.

Study the effect of ultraviolet radiation on the mechanical properties of vulcanizing rubber belts models

This study includes an experimental work to determine the effect of ultraviolet radiation (uv-rays) on the mechanical behavior of the conveyor rubber vulcanizing, which used in various transport operations, and in the cement plant Tartus. In this work, it has been prepared different samples of belts, and they were exposed to uv radiation at differente times, then they were tested to know its wear and tensile strength. The results were compared with samples similar to the samples tested, which was not exposed to the rays of UV, and with other samples exposed to temperatures, and that in order to reach the ideal conditions for the use of these belts, which ensures longer period of use and safe conditions. This study showed that uv-rays increase the average of wear and the tensile strength of belts.

Analytical and experimental study of the effect of noise background on the radioactivity measurement

In this experimental work, the instruments used (detector, calibrating sources) has been calibrating, the calibration line of the detector deduced and it has been finding that the equation of calibration line takes the form: The resolution power R has been studying as function of the distance between the activity source and detector; the results obtained show that R decrease by increase the energy of the lines spectrum, this mean that the detector resolution power become bigger. It has been measured the LC، LD and MDA using two different methods of background radiation value, trapezium method and classical method, for two different distances between radioactivity source and detector: (9,3cm) and (10cm). The results show: 1- There is similar comportment of the LC، LD and MDA in function energy and the distance between radioactivity source and detector. 2- The trapezium method gives better results from the classical method to the radiation background, and this leads to lesser MDA value, this means that the sensibility is bigger to measure this quantity. 3- The relative error using MDA is (5%) for large values, and (10%) for small values

The Prosthesis Implant Current Status in the Treatment of the Aneurysm ofthe Abdominal Aorta

The concept of Intravascular Technology is an advanced stage of the Medical vascular diseases therapy due to the easy usage by surgeon and the little rescue it involves on patients comparing to the traditional surgery. In this study, we have discussed one of the most modern methods of the Treatment of the Aneurysm of the Abdominal Aorta using the internal prosthesis through the artery. This has been achieved via the femoral artery. We also identified the prosthesis patterns and the used methods to get through those arteries as well as identifying the main indications and the importance of selecting the suitable patients regarding their age and health status. We also carried out a comparison among many International studies involving the development and usage of this technology worldwide. Indeed this therapy involves high material cost but the results prove its importance in rescuing many patients' lives that are classified to be in high rescue within traditional surgery.
