ABSTRACTThe main purpose of this research was to establish the effectiveness of the V844 corrosion inhibitor for seawater on various metallic materials: carbon steel, aluminum and copper alloy at different concentrations via colloid formation. The changes in both physical and chemical properties of seawater, including pH, total hardness, alkalinity, total dissolved solids (TDS) and conductivity at different concentrations of V844 were assessed, too. The test procedure involves dissolving the V844 corrosion inhibitor powder provided by Magna International Private Limited in seawater to obtain a stock solution of 4% V844 in seawater, which was further diluted to obtain the remaining concentrations. The analysis of parameters begun when various metal species, polished beforehand, were placed into the solutions. The analysis was observed over a period of 26 days and a total of 9 sets of readings were obtained. From our observation and analysis, it was concluded that the inhibitor worked best at 0.05% concentration for carbon steel.

This study was conducted to demonstrate the difference between drinking water quality for seven different areas of Kirkuk city with the treatment water in the main and three sub storages tanks, affected with drinking water pipe lines, supplying system Alternate and continuous and also pipes across the construction work’s areas. The physical and chemical properties (turbidity, pH, conductivity, Alkalinity, Total hardness, calcium, magnesium, chloride, sulfate, TDS (Total dissolve solids), TSS (Total suspended solids), sodium and potassium) for raw water and treated water in the Storages in addition to the supplying water from seven different areas in Kirkuk were analyzed, samples taken at a rate nine times during the month of March. Results showed that Drinking water of Dumez, Wasti, Shorja, Imam Qasim and Arubaa polluted with turbidity with an average levels of (8.68, 6.04, 7.41, 6.95, 7.64) NTU respectively, over the limit allowed by IBWA (International Bottled Water Association), 2012 and WHO (World Health Organization), 2006. The turbidity in the main and sub storages have reached (4.04, 4.09, 4.47, 4.16) NTU respectively, while other physical and chemical properties were within the allowed limits for human use. The pollution in those areas caused by the alternative supplying system of treatment water and it has negative impact on the pipelines, it includes constriction work in areas also where pipelines exist.

In this study, the concentrations of the physical properties such as the acidity number (pH), temperature (T), electrical conductivity (EC), total dissolved solids (TDS) and total hardness (TH) and, the chemical properties such as calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+), nitrates (NO3-), sulfates (SO42-), bicarbonate (HCO3-), phosphates (PO43-), fluoride (F-), and chloride (Cl-) in the groundwater in selected areas in Al-Dhalia district, Al-Dhalia,  governorate were determined by collecting water samples from 16 wells and thereafter the samples were analyzed, in the laboratory of the water resources authority in Aden, according to the recommended methods mentioned in the literature. The analysis results showed that most of the well water is not suitable for drinking due to their contents of some chemical and physical properties were exceeded the maximum permissible limit for WHO (1997) and Yemen ministry of water and environment (YMWE,1999).

Bioethanol is a clean and sustainable fuel; on the contrary, the addition of bioethanol to gasoline normally creates corrosion on automobile fuel system materials. In this study, corrosion characteristics of low carbon steel normally encountered in gasoline engine fuel system with bioethanol fuel was investigated. Static immersion tests in different fuel blends E0 (gasoline), E10 and E85 were carried out at room temperature for 1320 h. The mechanical, physical and chemical properties of low carbon steel before and after immersion tests were investigated. Moreover, the physical and chemical properties of fuel blends before and after immersion tests were investigated. The results revealed that the usage of E10 blend is considered feasible for gasoline engines in terms of materials compatibility compared to E85.

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.

Synthesis Of Materials

Biomimetics involves investigation of structure, function, and methods of synthesis of biological composite materials. The goal is to apply this information to the design and synthesis of materials for engineering applications.Properties of engineering materials are structure sensitive through the whole spectrum of dimensions from nanometer to macro scale. The goal in designing and processing of technological materials, therefore, is to control microstructural evolution at each of these dimensions so as to achieve predictable physical and chemical properties. Control at each successive level of dimension, however, is a major challenge as is the retention of integrity between successive levels. Engineering materials are rarely fabricated to achieve more than a few of the desired properties and the synthesis techniques usually involve high temperature or low pressure conditions that are energy inefficient and environmentally damaging.In contrast to human-made materials, organisms synthesize composites whose intricate structures are more controlled at each scale and hierarchical order.
