يهدف هذا البحث إلى التعرف على بعض مؤشرات النمو للأوكاليبتوس ضيق الورق Eucalyptus camaldulensis و أدائه البيئي، و دراسة عوامل المناخ و أثرها في تطور و نمو التجمعات الشجرية في مواقع تم تحديدها غربي محافظة حمص.
This study aims to recognize some growth characteristics of Eucalyptus camaldulensis and the effect of climate factors on trees growth and development. Negative trends were detected in annual rainfall according to meterological data taken from Homs station.

Generally, sewage sludge is dumped into sanitary landfills, even
though its use in forest stands as a fertilizer and soil conditioner
might be an interesting option. However, sewage sludge must be
applied with care to avoid soil and water pollutio
n. The aim of this
study was to assess the effects of applying dry sewage sludge on
wet biomass production and wood volume of short rotation
Eucalyptus camaldulensis plantation established on sandy soil in
Fedio plantation.
The importance of research being deals with the problem of
significant environmental concern the pollution of the plant , soil
and air component lead as a result of rapid industrial development
since the twentieth century . Was selected Eucalyptus
for several
considerations , including the widening spread and being one of
the bumpers wind that might ease the arrival of pollutants in the
atmosphere to regions far geographically . was selected several
sites of Homs in order to examine the content of the soil and
leaves Eucalyptus from a bullet was found that the concentration
of lead element in the plant was caused by air pollution , where not
shown the existence of relations clear engagement between the
content of soils of lead ( for a total and disposable absorption )
with the lead content of the plant . Ranged concentration of lead
overall in the soil between 1.98 ppm ( through Homs - peaceful )
and 72.47 ppm ( Highway Tartus in the south ) , and the average
of 4.857 ppm, did not exceed the concentration of lead in the
samples studied , both inside the city or outside the normal limit
and values lead stainless absorption in the soil ranged from ppm
(19.02- 0.02), ranged lead concentration in the plant between
2.01ppm and 10.35ppm and this concentration of lead element
within the permissible limits but with time become toxic showing a
lack of liaison relationships between the component lead either in
the soil or plant with the CaCO3 and Active lime. Finally we can
say that the contamination of the plant within the city is higher than elsewhere because of the busy traffic . Add to that the increase in soil lead content available led to increase the concentration of lead in Eucalyptus,leaves
This study was carried out during 2013 – 2015 and aimed to assess the effects of
applying dry sewage sludge on dry biomass production and wood volume of Eucalyptus
camaldulensis plantation established on sandy soil in Fedio plantation-Lattakia at A
pril -
2013.
Four experimental treatments were compared at age 22 months: SS1 (sewage sludge
3 kg/tree), SS2 (sewage sludge 6 kg/tree), MF (mineral fertilizer), and C (no fertilizer
applications). Aboveground dry biomass production and wood volume in the SS1
treatment were about 107.60 t/ ha and 121.13 m3/harespectively, MF treatment (87.52 t/ha,
96.98 m3/ha) and SS2 treatment (91.12 t/ha, 103.42 m3/ha)and higher than in the control
treatment (43.89 t/ha, 51.32 m3/ha ).
The environmental and biological study of the olive moth Prays Oleae.B was conducted in the Natural Resources Research Department of Homs Research Center in 2015-2016, where seasonal changes of the olive moth P. oleae group were monitored using pheromone sexual attraction traps.
In this paper, the thermal
performance of the doctors and nurses housing building in Aleppo
walls, consisting of the hollow blocks with inside styropor sheet and
compare it with a wall consisting of hollow blocks with eternal
continuous insulatin
g styropor layer and the effect of adding
continuous insulating layer on the existing walls.
The study showed that the use of the block with inside styropor slice
was not useful regarding the thermal behavior and causing large and
intense thermal bridges generation. However the use of block with
continuous styropor layer made the temperature distribution more
uniform and reduced the energy flux by 36.7-70%.
