Soil water erosion is a major factor of land degradation in the coastal slopes of Syria, and in the long run represents a real threat to the environment and natural resources such as soil, water and vegetation cover.
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).
Rural transport is one of the basic requirements imposed by the daily life conditions,
so it should be has of certain conditions and basic standards which it purposed of achieving
customer satisfaction and reach the level of a certain quality of se
rvice provided by rural
public transport. For that, Many studies were focusing on a number of most important
criteria such as the waiting periods, comfort, safety, adherence regular capacity of bus,
commitment tariff set for the fare, In addition to the commitment to a specific time.
In this research, interviews with a random sample of residents of Sheikh Badr City
were producted in order to obtain the information needed to evaluation the quality and
appropriateness of public transport services on the line of Tartous-Sheikh Badr. After that
we recorded the data obtained and analyzed the results using the program (excel). One of
the most important results that we have obtained is the length of the waiting period, which
ranged from 50-60 minutes.
Search finished with evaluation the public transport, suggestions and
recommendations to improve the efficiency of transport in rural areas.
The Research aimed to use the technology of the fermentation to produce the biogas from the cow manure. The digester has benn carried according to the Indian model. The digester consit of one cylinerical tank with 9.42m3 volume (height 3m, diameter 2
m) and gastank with 6m3 (height 1m) and inlet pipe and outlet pipe. The study showed the following:
The accumulated production of biogas was through the 30 days retention time 48m3. The heighest production was in the thirteenth day with 4.5m3. The farm became after the use of digester clean and with little insect and smell.
With use 1m3 of biogas could we use one cooker for 2.5 hour and with the same quantity could we use one inner combustion diesel motor (90% biogas and 10% diesel) for half an hour.
3/4m3 from digester volume is enough for one cow with 12 kg manure daily. So we can design the suitable digester for any farm.
the residual lead effect in cows milk was
studied in the Governant of Tartous. For this end,135 dairy cows in
different milking seasons and from three different farm stationes
(Zahed cow station,Cement factory farm station and Banias refinery
cow
station) were used.
The objective of the study was to accurately determine lead
concectrations in cows milk in the three different farms. Samples of
milk,soil,water and feedstuff were collected and lead concentration
was determined then statistically analyzed.
