The salt water mixes with fresh water and forms brackish water. The brackish water contains some quantity of salt, but not equal to sea water. Salinity determines the geographic distribution of the number of marshes found in estuary. Hence salinity is a very important environmental factor in estuary system. Sand is one major natural aggregate, required in construction industry mainly for the manufacture of concrete. The availability of good river sand is reduced due to salinity. The quality of sand available from estuarine regions is adversely affected due to this reason. It is the responsibility of engineers to check the quality of sand and its strength parameters before using it for any construction purpose. Presence of salt content in natural aggregates or manufactured aggregates is the cause for corrosion in steel. In this study the amount of salinity present in estuary sand was determined. Three different methods were used to determine the salinity in different seasonal variations. The sand sample collected nearer to the sea was found to be high in salinity in all methods.  It can be concluded that care should be taken before we use estuary sand as a construction material due to the presence of salinity.

Quality Of Learning

Vocational schools (SMK) is a secondary education that preparesstudents primarily for working on a particular field. Diverse efforts made by SMKgraduates increased 8 Medan include improving the quality of education byreforming both the substance of the material and the provision of facilities andinfrastructure. However, the results have not been up, cermatan can be seen fromthe low competence of graduates, making it less able to play a role in meeting thedemands of the workplace. Assumed to be an indication of the quality of learning isstill performed during less effective, less efficient and unable to increase studentinterest. In order to achieve maximum learning outcomes is through theimprovement of learning strategies to utilize the educational facilities in accordancewith existing conditions, ie, by examining one of the subjects namely Constructiondressmaking pattern. Construction material pattern done with learning strategyapproach manipulated into two comparing results STAD cooperative learningstrategies and learning strategies expository and compare the results with thelearning characteristics of students with high and low interest in learning onlearning outcomes Pattern Construction.

Vibration Problems

In this paper, mathematical model of nonlinear vibration problems with fluid flows through pipelines have been developed. Using the Bubnov–Galerkin method for the boundary conditions, the resulting nonlinear integro-differential equations with partial derivatives are reduced to solving systems of nonlinear ordinary integro-differential equations with both constant and variable coefficients as functions of time.A system of algebraic equations is obtained according to numerical method for the unknowns. The influence of the singularity of heredity kernels on the vibrations of structures possessing viscoelastic properties is numerically investigated.It was found that the determination of the effect of viscoelastic properties of the construction material on vibrations of the pipeline with a flowing liquid requires applying weakly singular hereditary kernels with an Abel type singularity.

Research Results

The construction materialindustry is one of the most rapidly growing sectors, with many achievements both in Vietnam and in Asia. In recent years, its rapid growth has produced revenues from business activities. One of the key objectives of thispaper is to assess market risk volatility in construction material businesses in the 2012-2014 pre-low inflation period. Our first findings are to be found that beta values in general (< 1) for most of our constructionmaterialcompanies are appropriate when we apply quantitative, statistical and analytical methods to evaluate the asset beta and beta CAPM of 20 listed Viet Nam construction materialcompanies.However, we analyze the market risk volatility, determined byasset and equitybeta var, during the post-low inflation period in thissector and compare results in two circumstances: risk fluctuation in pre-law inflation time 2012-14is lower than that in post-low inflation period 2015-2017.Finally, if we observe in2 periods, BetaCAPM or equity beta mean goes up in case post-low inflation period. At last, policies in risk management and governance are suggested in the conclusion based on the research results and findings. In the post-low inflation environment, we alert that Beta fluctuations could bea little higher.JEL classification numbers:G00, G390, C83
