Since the beginning of the twentieth century, researchers have isolated and dentified spreaded and adapted yeasts to variow environmental conditions and the types of the mediums in which they graw. The industrial features of the isolated genera, e specially those used in the food processing and the stability of their genetic characteristics were studied. Yeasts in medical and industrial fields were also improved.
قمنا في هذه الدراسة، و من خلال عينات من الرخويات، جمعت من القطاعات المختلفة لمحافظة ريف دمشق، بالتعرف على مجمعات أنواع الرخويات الأرضية المنتشرة فيها و قد سجلنا وجود ثمانية أنواع تنتمي إلى فصائل أربع: اثنان ينتميان إلى فصيلة Enidae و نوع ينتمي إلى فصيلة Leucochroeidés و أربعة أنواع تنتمي إلى فصيلة Helicidae و نوع ينتمي إلى فصيلة Helicellidae.
In this research, the natural pyrite ore found in Tartous Governorate was described by studying the two samples taken from Hosn Suleiman -Safita (A) and Al Qadmous (B) area, in addition to studying the optimum conditions for pyrite dissolution (pH - time - quantity) with aerobic conditions. The results of X-ray diffraction (XRD) showed that the sample (A) is mainly composed of pyrite mineral and does not contain impurities, while sample (B) is composed of pyrite mineral combined with a small amount of calcite mineral, and these results were confirmed by the result of (FTIR) infrared spectroscopy and Polarised light microscopy (PLM(. The iron percentage in the two samples (A,B) is ranged between (42.6 – 43 %) and the sulfur percentage is between (40 – 53.7 %). With regard to pyrite dissolution, the results showed that pyrite taken from Hosn Suleiman (A) begins to dissolve at pH values less than 4.5, and the contact time is about 6 hours. By Comparing the results of sample (A) with sample (B), we found that the dissolution of sample (A) was about three times less than the dissolution of sample (B), and this is due to the fact that sample (A) contains pure and well crystallized pyrite ore while sample (B) contains pyrite combind with calcite, which increases its solubility.
The study was conducted in four sites belonging to the Sheikh Badr district in Tartous province. Ten different types were identified according to international standards. During the 2016 and 2017 growth seasons, readings were recorded for phenotypi c parameters as well as physical and chemical analysis of fruit clusters. The studied types differed in many characteristics. The results of the cluster analysis showed the distribution of the studied types in two groups with a variance of 93%. The mean weight of the cluster varied between the medium (349 g) and the large (1140.45 g). The ratio of total dissolved solids (TSS) between the low (12.75%) and high (18.82%). the acidity between the very low (3.53 g/l) and medium (6.38 g/l).
