The study was performed to discover parasitic Nematoda in
digestive system of Siganus rivulatus (Forsskal and Niebuhr, 1775) in
beach water of Lattakia, and investigation the role of some ecological
parameters on its distribution.
Vertical sampling process took place to Copepoda during the summer and winter of
2009 and 2010 from Alzzouzo castle which is located in the coastal region of Jableh city.
This region has special environmental properties. Sampling was accompanied wi
th
measuring water temperature, salinity, and dissolved oxygen in the water.
The total number of samples studied in all areas of study is 106 samples. 100 species
were identified during the summer, while 89 species were identified during the winter;
most species belongs to the order of Calanoida. It was noted by the study that most species
appeared in two seasons together, while some species appeared in the season without the
other. It was also noted that the abundance of Copepoda was higher in summer with an
average of (5314 individual / m
3), while the average in winter was (4353, 40 individual / m
3).
It was clear from the study that the station near the beach was less diverse and more
prolific than the offshore station during the summer and winter together.
This study was conducted on the type of the Syrian pear, Pyrus syriaca. Boiss spread wildly in the Qardaha area in Lattakia governorate during the years 2012-2013 AD. Nine phenotypic phenotypes scattered in different locations (Ain Al-Arous - Deir Hanna - Basin) were studied, where the results showed that there were differences in some traits out of 14 studied phenotypic traits.
This study was performed the existence of the species Datura innoxia Mill. in the Syrian
flora. Also the morphological study results showed that the plant is a gray greenish herb,
its stem is erect. Leaves are simple, alternated, oval, its angle is
turbinated to the out. The
root is sphenoid.
The flower is regular. The fruit is capsule, and the seed is splay, have an excrescence.
The palynological study showed that the pollens are ellipticity, triad of germination lines.
Whereas, the anatomical study showed that the form of carrier packing take quadric side
type.
The research aimed to identify the level of creative thinking skills (fluency,
flexibility, originality, whole degree) among basic fourth class students in Latakia, in the
light of gender. To achieve this purpose, the researcher used Torrance test
of creative
thinking-vocabulary form (A). The sample consisted of (255) students (125 males and130
females)selected by using random sampling method, from several schools in Latakia, The
results showed weakness in the level of creative thinking among basic fourth class
students. The average of degrees were(the whole degree95.21, fluency 46.85, flexibility
28.27,and originality 20.08), The results also showed that there were no statistically
significant differences in each skill of creative thinking (fluency, originality, and whole
degree) due to gender, but there were statistically significant differences in degree of
flexibility in favor of females. In the light of the findings, the study suggested merging the
skills of creative thinking in curriculum, and teaching these skills independently, fasten
training session to teachers to habituation them on development of creative thinking during
the class teaching, and setting up tests to measure creative thinking skills codified in Syrian
environment, and conducting new researches focusing on creative thinking (from where
measuring and development him) in different school levels, with using other variables.
