الهدف من البحث هو حساب انبعاثات ثاني أوكسيد الكربون الناتجة عن صناعة الاسمنت (شركة اسمنت طرطوس كحالة دراسية ), اعتماداً على المعايير و المبادئ التي حددها معهد الموارد العالمي و كذلك مجلس الأعمال العالمي للتنمية المستدامة بالإضافة إلى المعايير و المبادئ التوجيهية لهيئة المستشارين العالمية لتغير المناخ .
The aim of research is to calculate the emissions of carbon dioxide (CO2) generated by the cement industry (Tartous Cement Company as a case study), depending on the standards and principles set by the World Resources Institute protocol (WRI) and the World Business Council for Sustainable Development Protocol (WBCSD 2011), in addition to standards and guidelines developed by the Intergovernmental Panel on Climate Change (IPCC 2007).

This research focuses on identifying spatial and temporal variationsof the carbon
dioxide system in the surface seawater of Tartouscityduring the period betweenspring and
summer 2015.In Addition to the extent influenced by some hydrological propert
ies of
water (temperature and salinity) and the impact all of this on the pH of marine water
values.
The results showed low partial pressure of the carbon dioxide in seawaters (PCO2
sea)
in the summercompared with spring, which is reflected on the air-sea flux values (FCO2),
where CO2 released from surface seawater to the air in summer and incontradiction of that
in the spring (0.0632mmol /m²/ day and -0.0715 mmol /m²/day, respectively). In spring,
low temperature and salinity of the water (22.707-22.727C and 37.605-37.765‰
respectively), in addition to increased biological activity contributed in increasing the
absorption of CO2 from the water.These leading to a decrease PCO2
sea (409.0- 429.5μatm)
associated with low concentrations of all of the total inorganic carbon (2229.5-
2242.5μmol/kg) and total alkalinity (2588.873-2590.9μmol/kg). and as a result the surface
sea waters become a reservoir of dioxide carbon atmospheric.
In the summer, the rise in temperature and salinity of surface seawater (28.85-
29.60Cand38.15-38.60‰, respectively) and reduced biological activity all contributed to
the decrease dissolved CO2 values and increase of PCO2
sea(437.5 - 453.5μatm)
associated with increasing concentrations of each of the total inorganic carbon
(2267.9 - 2296.0μmol/kg) and total alkalinity (2739.6 -2741.2μmol/kg).In this way the
surface sea water is source of carbon dioxide to the atmosphere.
In this paper, the seasonal variations of CO2 system and pH
values in surface seawater of Banias city are shown during the
period in spring 2015 and winter 2016, in addition to determine the
impact of hydrological factors.
The administrative corruption phenomenon is global and is widely and deeplyrooted that
takes a broad dimensions with various factors that are difficult to distinguish between them. The
degree of coverage varies from one society to another. The deva
stating effects and consequences of
this phenomenon affects all life of all people, wastes resourcesand impede the fulfillment of
responsibilities, functions and services, and thus constitute a system of sabotage and delay in
construction and development process, not on the administrative and financial levels, but also
political, economic, social and cultural levels, necessitating an effective independent regulatory
system controls and follows-up practices of Ministers and officials in all ministries and institutions.
Hence this research examines the role of administrative control in the fight against
corruption in Syria industry companies (example about this companies Tartous companyfor
Cement And Building materials Industry)in side and to evaluate the most important causes of
corruption and the weakness and shortcomings in the regulatory procedures and processes in other
side. The researcher addressed the concept of administrative supervision and its importance to the
phenomenon of corruption and its causes, and how to address them, as well as the importance of
control in the fight against corruption. The researcher concluded at the end of this research to a
group of important conclusions: there are differences between control methods which have used
tocombat corruption in Tartous Companyfor Cement And Building materials Industry, and the
modern quantity methods and modern analyses control methods.
In the end the researcher put forward a set of proposals and recommendations, including: the
need to address the factors that contribute to the low level of control, and poor planning for
effective control procedures, and lack of accountability and justice that could be the cause of
corruption.
The weigh feeders constitute an essential part of any production facility, where its
control and supervision system is one of the important things that should be characterized
by precision and reliability.
From this research we will try to develop
the unreliable control and supervision
system of the weigh feeders in mills of raw materials department in Tartous cement and
building materials company. The work Will focus on trying to avoid errors and problems
that the old control system suffered in order to reach the best possible performance of
weigh feeders, facilitate maintenance process and reveal the problems as they happen by
proposing controlled weigh feeders by programmable logical controllers from SIEMENS
corporation with processor (CPU 315-2 PN / DP), and design supervision and collection
data system using software (WINCC Flexible sp3 2008).
We'll apply the steps of the study practical on the weigh feeder of mill of raw
materials, and we will conduct the necessary tests to ensure the validity and accuracy of the
new control system, therefore the range of reliability.
This study includes an experimental work to determine the effect of dilution on
Hardfacing welding of clinker hammer crusher. In this work, samples have been prepared
from the same metal type of hammer’s, of which is X120Mn12. Then the samples had
been hardfaced using deferent kind of hardfacing Shielded Metal Arc Welding electrodes,
and using deferent welding parameters (current, polarity), the calculation and measuring of
dilution had done and then performed the hardness tests, wear tests, and their relation with
dilution.
This study showed that the reduction of heat input decreases dilution as the hardness
of hardfaced samples increases and wear decreases.
Direct current electrode positive (DCEP) increase dilution as the hardness of
hardfaced samples decreases and wear increases, but the quality of the welding became
better. Results showed that percentage of chromium and carbon in electrodes have positive
effect on hardness.
