In this research an experimental study has been carried out
to investigate the enhancement of Bosra Alsham´s soil (120 km
south Damascus) by using crushed glass wastes additives by using
experimental approach. The soil samples were taken from Bosr
a
(2m underground surface), which is classified as highly plastic
clayey soil CH according to unified classification.
The study was
aimed to the determine the types of medical wastes produced by
hospitals and having clearly panorama picture on the reality of
management of medical wastes in some hospitals in Hama govern
ate and the methods of treatment and sugges
ted the suitable
solutions and safely environmentally to manage these wastes
according the results the mentioned research.
As a result of the growing interest in environmental issues in the Syrian environment,
more precisely in the health service sector, companies in various sectors are facing the
problem of measuring and analyzing environmental costs, and disclosing e
nvironmental
costs in their financial statements. This research explores the role of measuring and
classifying environmental costs in decision-making in the health sector.
A case study was conducted in the General Authority of the Basel Hospital in
Tartous in Syria. Data was collected using observations and analysis of hospital
documents and reports, and personal interviews with managers and heads of departments
and accountants in the hospital.
The research aimed at finding a proposed model for classifying environmental costs
in the hospital based on Shapiro's model. The results showed that the cost of acquisition,
supply cost, training and qualification, storage costs, obsolescence costs, disposal costs,
maintenance costs are considered appropriate to make environmental decision-making. The
study also showed that the lack of knowledge and awareness of the administrative and
accounting staff about concepts and terminology of environmental accounting adversely
affect the process of tracking and measuring the environmental costs and hence the quality
of environmental decisions. The results showed also that the hospital is almost committed
completely to sort and separate medical and non-medical waste in all divisions and
sections.
The recycled concrete aggregate RCA was able to take the place of the vierge &
natural aggregate NA, embankments elected,to implement the base&subbase road layaers
and airports in many country of the world.furthermore, there is almost consensus by
a large
of reshershers and scholars about the possibility of using RCA in mix cement concrete for
non-structural elements .whil,the using of RCA in the hot mix asphalt HMA still under
discussion and debate, due its high porosity , high water absorption, and its heterogeneity
which reflected negatively on the mechanical and physical properties of the HMA
This research discusses stadying the possibility of using the recycled concrete
aggregates in hot mix asphalt HMA, for the implementation of the bas layer bituminous
road , by the application of the marshall tests on hot mixtures asphalts have ben prepared
using different ratios of recycled concrete aggregates.
The results of marshall testes showed that the HMA prepared with amount of
recycled concrete aggregates less than 50%,can be used to implement the base layer
bituminous road,according to the general terms and specifications book for road works and
bridges in the syrien arab republic.
The recycling of debris, is considered as one of the most important resources for
constructing base &subbase road layers in many countries.
There are two problems for RCA: first, the considerable size it takes up when
collected and second, its low
technical properties. The second problem appears in
countries which don't have natural quarries and they have to use RCA in certain fields
(concrete mixes, asphalt mixes, granular road layers).
This research discuses preparing RCA aggregates, by recycling the concrete waste,
which comes from Al-Sallima landfill, near to Damascus city. Then many tests are carried
out to study the effect of changing the aggregate's size on their mechanical & physical
properties, and also to study the possibility of using these aggregates in constructing base
&subbase road layers.
As a result, it has been found that we can use RCA for constructing unbound base
&subbase road layers, and the mechanical & physical properties of these RCA get better
when the aggregate's size gets smaller, except in Proctor test. In this test, Proctor density
and optimum moisture content get better when aggregate's size gets bigger.
The research had performed in Tartous county at Alsinaea area and Faculty of Technical Engineering in year 2012 .This investigation had confirmed the possibility of quick dispose of byrene and the possibility of byrene manufacture through byrene pre
ss and producing pieces for heating or producing barbecue charcoal. This products are with little smoke, smell and environment friendly. The results showed the following:
1- Producing pieces of byrene for heating with the possibility of controlling the strength and the press of pieces. With this we can contribule to environment protection and loosen the problem of heating in winter.
2- The comparison of organic fertilizer (Compost) from Byrene with mixture fertilizer from oak, straw and cock waste showed moral differences for nitrogen and kalium and no moral differences for organic substance, ashes, phosphourus and PH. The compost contains a little of Poly Phenolic. The SHETIANZY number for compost was with cold and hot water 0.277, 8.22, respectively and for mixture fertilizer 10, 16.
3- It was no moral differences between the specific heat and heat of combustion. The less moral difference was for both 0.430, 1.054, respectively. The barbecue charcoal from Dakka was with little smoke, smell and quick combustion. The producing cost of 1 kg was 5 syrian pounds
In this study, extracts from onion solid wastes were prepared
and added to tomato paste in different concentrations (1000, 2000,5000 ppm). Tomato paste was stored under room temperature for (0.5, 1, 2, 4, 6, 8 and 12 months). Microbial load (total a
erobic bacteria count, total mold, and yeast count) of tomato paste samples was studied after storage.
The results showed that addition of onion wastes' extract at
5000ppm reduced aerobic bacteria load by (1.06 log CFU/gf), and the molds and yeasts by (1.37 log CFU/gf) before storage. After storage for 12 months, the increase in microbial load was the lowest in this sample and it reaches (0.91 log CFU/gf) for the aerobic bacteria, and (0.81 log CFU/gf) for the molds and yeasts.
The possibility of using onion wastes' extract (5000ppm) as
an alternative to sodium benzoate was studied. The results showed the possibility to reduce the percentage of added sodium benzoate from 0.1% to 0.07% while keeping the total bacteria count within the acceptable level after storage for 12 months..
