A pilot unit was constructed and operated to study the ability of treating polluted water
using biological treatment. The experimental unit consists of water sprayer unit that ensure
wetting of the filtered media and distributing water in a homogen
ous manner as well as
increasing the dissolved oxygen concentration in water. The sprayer unit is followed by a
biological filter; the area of the filtered media was (13) m2. The developed biological film
placed on the filtered media will dismantle the organic matter, which reduce nitrates to
nitrite then to a nitrogen gas. The filter was connected to an aeration basin where the
suspended growth was archived. The pilot unit was operated depending on the water was
taking from a manhole nearby the residential unit number 18. The average efficiency of
BOD5 removing was 69.4% and of nitrate, removing was 34%. The results showed that
this system can improve water's characteristics.
Information and communication technology (ICT), Gross capital formation,
Openness, and Inflation are frequently well-thought-out as important drivers of economic
growth for all countries, and especially for developing countries. This study aims to
examine the effect of these factors no economic growth in Syria covering the period from
1995-2012, with main interest of the impact of ICT. To this end, the study utilized annual
time series data set over the period 1990 to 2010. Econometric techniques include testing
the stationary of data by applying (ADF) test and applying Autoregressive Distributed Lag
(ARDL) method of estimation. Moreover, Short run and long run estimates were found .
The paper confirms a negative and statistically significant relationship between the
economic growth and technology index in the short run, but the relationship becomes
positive and statistically significant in the long run. This paper confirms a negative and
statistically significant relationship between the economic growth and GFC in the short
run, but the relationship becomes positive and statistically significant in the long run,
where the relationship between openness and economic growth is positive both in the short
and long run, whereas the relationship between the inflation rate and economic growth is
negative both in the short and long run.
This research aimed to study the effect of adding different rates of lysine on the weight and
growth of common carp fingerlings. The experiment was carried out in the laboratory for 4
months using eight glass containers (40 liters each) with four t
reatments (L0 no Lysine
addition, L1 (2%), L2 (3%), L3(4%) of the total weight of diet. Eight common carp
fingerlings (average of tall 7.5cm ± 0.05 and average of weight 12.25g ± 0.57) were
cultured in each container with Oxygen pumps and filters.
Results showed by growth rate, absolute growth rate, specific growth rate and food
conversion ratio (FCR) that the treatment L1 (2% lysine) was significantly the best
comparing to the other treatments, where FCR was (2.2) and the specific growth ratio was
(0.28 %)
Cauliflower silicified geodes within Slunfeh Formation of
upper cretaceous were described. Mid-range infrared spectroscopy
FTIR was used for determination of mineral composition of these
geodes. Polarized light microscope was used for the study of
thin
sections taken from inner parts of geodes in order to determine their
crystal habits. The results showed that geodes of studied formation
consists of silicon in form of amorphous to cryptocrystalline opal,
chalcedony of micro-crystalline fibrous radial structure, hexagonal
prismatic quartz, radial quartz, zoned quartz and mosaic quartz.
This study aimed to
investigate the validity of measuring IGFBP-3 in the serum of
Syrian children with acute lymphoblastic leukemia (ALL) as
additional markers in diagnosis and follow-up of the disease.
A study on the propagation of female kiwi trees (Hayward variety) by wooden
cuttings, using plant growth regulators, was conducted at Latakia Agricultural
Research Centre during the seasons 2009, 2011 and 2012. Two dates for collecting
cuttings (J
anuary and February) from kiwi trees which were selected. On each date,
the cuttings were divided into three groups according to cutting location on the
shoot (basal, middle and apical). The NAA and IBA growth regulators were applied
at several concentrations, in addition to two treatments of the mixture of both growth
regulators.
The Akaike information criterion (AIC) is a measure of the relative
quality of statistical models for a given set of data.
The Schwarz
Criterion (SC) is a measure to help in the selection between
candidate models.
The research was carried out during 2014 and 2015 agricutural
season ,To study the effect of spraying cytokinin regulator on
vigitative and fruiting charachterstics cotton plant.
The research was carried out in the fields of Akar plain in Tartous
province during two seasons (2013, 2014) to study the effect the three
multiplication methods (Slips as control, Seedling, Cut-seed tuber) on
growth and yield of two locally sprea
d sweet potato varieties. The
experimental design was a randomized complete block with three
replications. Data were analyzed using the statistical program GenStat 12.
The research aims to study the effect of the treatment of the
eggplant seeds- pink local kind in some seaweed extracts to improve
the germination characteristics, as well as the study of their impact
on the growth of the resulting seedlings and their ability to
withstand the transplanting shock.
