The behavior of the basaltic shear diaphragms of the remaining buildings of ancient times
was investigated as experimental research,and its resistance to natural factors and
horizontal loads resulting from wind and earthquakes,to take advantage of
them in the
maintenance of modern buildings,which are associated with floors and beams as horizontal
shear diaphragmsIn the hot and cold areas of the African continent, Asia and other similar
areas,to replace the reinforced concrete shear diaphragms,and metal shear diaphragms that
lose their resistance to the above factors. When the buildings are inspected, the vertical and
slanted slits resulting from the side loads are placed,it was found that the appearance of the
cracks related to the hardness of the shear diaphragm section, the basalt stone
specifications and the design of the shear diaphragm base.The research was conducted
to determine the durability, water permeability and resistance to pressure and tensile
strength of basalt stone samples used in historic stone buildings and their location in
laboratory methods.Horizontal loads resulting from seismic intensity were determined on
the front of the building at the tile level according to international requirements and
specifications.The method of calculating the basaltic shear diaphragms was
applied by applying arithmetic to build a basalt stone from several floors and a basement,
taking into account the characteristic resistance of basalt, depending on its density from
pressure and stretching and basalt stone in calculating.
Experiments Has been made on lime mortar which have a weak
resistance so we added materials like pozolan, and bricks to
improve the mechanical properties of the mixture, as we added
fiberglass to the mix, and study their effect on the mechanical
properties of mortar, also experiments has been made on natural
limestone which used in the construction, experiments on samples
of mural prismatic composed of stone and mortar to see pressure
strength of mural samples, and mural samples subjected to
curvature to determine tensile strength of stone walls with
limestone mortar reinforced with fiber glass.
We observed increase in the mural samples tensile strength about
73% when we added a small amount of fiber glass doesn't exceed
2% of the proportion of the existing lime in the mixture, which
shows the effective improvement in the mortar extracted
specifications.
The study was achieved in 2014-2015 at Dahr Khribat stone pine forest, Latakia. to
determine the factors affecting the natural regeneration of the stand. The results of climate
studies indicated that the region is located in the semi-wet climate fl
oor with a mild winter
as the average of rainfall thermal coefficient reached (Q2 = 72.01). The study showed that
the low productivity of cones (20 kg con / tree) was one of the limiting factors of natural
regeneration. The trees high density (462 tree / ha), led to a decrease in tree diameter at
breast level (30 cm) and low coronary size (320.2 m3).
Seed germination was not affected by illumination periods, while salinity levels led
to a significant decrease in germination from 90% at control to 19% at 0.5 mol / l.
All of one year old sapling or seedling were dead during summer months, while more
than 90% of two years old cultivated sapling, survived in all treatments, but no significant
differences among them.
Restoration of ancient structures is an important part of
reconstruction process which will be witnessed by our country, the
aim of this research is to improve a local manufacturers lime mortar.
In this study a total of /14/ fungal genera have been isolated from seeds; seedlings roots and soilsofCypress and Pine species (brutia; canary and stone) samples brought from Hinnade's nursery, and it were: Alternaria; Rhizoctoni; Fusarium; Chaetomiu
m; Mucor; Phythophtora; Rhizopus; Aspergillus; Penicillium; Cladosporium; Saccharomyces; Sordaria; Pytiumand Trichoderma. The first 12 genera were isolated from seeds. Alternaria andFusarium appeared on alldifferent types of plants with the highest frequency of the first genus 23.3% and 36.6% of the second one on cypress. The first 5 genera were isolated from seedlings roots in addition to genus Pythium. And also the Genus Fusariumwas frequented on all study types with high frequencies reached to 58.5%onbrutia.The genusRhizoctoniawas not isolated from seeds and roots of Cypress while it was isolated from seeds and roots of all species of pine./7/ fungal genera were isolated from seedlings soils three of it (Alternaria,Aspergillus,Fusarium) were isolated from the soils of all species of plants with the highest percentages of the first 68.97% on cypress's soil and 22.22% of the second from stone pine and 35.13%of the genusFusarium from brutia. The highest frequency was for genus Fusarium 35.13% on brutia. The genusPythium was onlyisolated from the seeds and soils of brutia pine.
In addition to the aesthetic role of buildings' façade stone coverage, there are many expected issues of this process notably identity and environmental friendly.
This process is often used superficially and inappropriately in many cases it has been
used for marketing purposes, sometimes resulting in an abuse of the goals and the process which was created for and deteriorated badly even the local identity of the city. Unfortunately, many of the architects were involved in the abuse. Hence the research finds the need to identify ways to use the texture in design and implementation processes, methods and the success of the use of stone environmentally, its success and the reasons for its failure to address the problems in Lattakia city, through knowledge of the advantages and disadvantages of stone and methods.
This research aims to study the effect of stone columns on
the change of settlement in clay soils.
We defined the stone column and its uses , We explained
the transfer mechanism of load to the soil .
We spoke about important theories which discus
s the
settlement of clay soil reinforced by stone columns (Priebe
theory) .
we used the unite cell idea to study the settlement behavior
in the clay soils affected by the stone column to generalize
the study on unlimited loading area of clay soils , so we has
been defined some of the basics which relate to the unit cell
.We made a group of tests on a small model to define the
settlement of clay soils in the case of absence of stone
columns and in the case of presence of stone columns with
different diameters to know the change of the settlement
with the change of area replacement ratio inside the unite
cell , then we compared the laboratory tests results with the
results of Priebe (1995) .
The possibility of using some agents used in traditional medicin .
Neoziland rabbits was used as experimental animals ; Fossil encrinites was used as a
treatment drug ; the disease was induced by injecting 120 mg of sodium glyoxylate intraperitonea
lly .
kidney calculi disease is a common health problem. At least 5% of women and 12% of men during their
lives suffer from kidney stones. Lots of herbal drugs and medicinal preparations are used in our country
in the treatment of kidney stones.
This study was carried out at three different forest sites in Syria in order to
determine the effect of changing rainfall, temperature and soil on kernel
productivity of stone pine (Pinus pinea L.)> these sites included: Jabal Alnabi
Mata, (Tartou
s province, L1), Dahr Alkhoser (Homs province, L2) and E′en
Jron site (Idleb province, L3). Results showed that kernel productivity of stone
pine per tree was 236.3, 252.8, 143 g per tree, and 177, 162.3, and 86.98 kg per
hectare in L1, L2, and L3, respectively. These differences were attributed due
to the variation in the composition, textured and fertility of the soil available in
the three locations studied. It was concluded that trees of stone pine grow better
and superior in Kernel productivity in humid and super-humid bioclimatic
zone.
It is known that (Z×Z) is a semigroup with respect to addition, and it can
be endowed with the discrete topology; where Z is the set of integers. We can
make β(Z×Z), the Stone –Cech compactification of (Z×Z), a right –
topological semi group (Baker & Butcher).
