The study was conducted to assess Senior High School Science Students’ proficiency level in planning practical activities for ‘Test of Practical’ with selected topics from the Integrated Science syllabus. A total of 180 respondents (90 male and 90 females) out of a population of 1029 were sampled from three senior high schools in the Municipal Education, Offinso. Computer generated random numbers were used to randomly select 30 males and 30 females from each school in the municipality. The study employed the performed task instrument. Three tasks on planning were developed with their scoring formats and scoring details. Task A was on ‘distillation’. Task B on ‘density’ and task C on ‘osmosis’. A pilot test was conducted in one of the seniorhigh technical schools in the Atwima Nwabiagya District Educationand the response dichotomously scored, internal reliabilityof the various tasks was assessed using Kuder Richardson 20. The reliability of the various tasks obtained were task A, (0.731); B, (0.945); and C, (0.86). the data obtained for the actual study were statistically analyzed using descriptive, (percentages and means) inferential statistics (Independent t-test and Analysis of variance(ANOVA)). The students exhibitedhigh proficiency on the planningskills. There were many similarities between the performances of female and male students of the various schools. The performance of students of school A were statistically significantly different fromschools B and C on task B. from the major findings of this study, it is recommended that ‘Test of Practical’ questions should be related to  real life situations

This research is aimed to analyze Corporate Social Responsibility Disclosure toward the Firm Value.Dependent variable in this research was Firm Value related party tobins’q. Independent variables in thisresearch Corporate Social Responsibility Disclosure, This research used secondary data analysis of financialstatements or annual reports of exclude financial company and bank at Indonesia Stock Exchange in 2014 -2016. By using purposive sampling method, the total amount of samples obtained in this research were 201from 67 companies. This research used data panel regression analysis method. The results of the analysis inthis research showed that Corporate Social Responsibility Disclosure didn’t effect toward the firm value

Because traditional assessing methods usually yield extreme results and are of poor resolution, a set pair analysis based on triangular fuzzy number is established. Set pair analysis method is an uncertainty analysis method of the system whose formula structure analysis of connection degree is established by the identity degree, discrepancy degree and contrary degree to deal with all kinds of uncertainty and fuzzy problems. The measured value and the lake quality criteria are two interrelated sets put together to compose a set pair with respect to the problem of determination of the magnitude of lake eutrophication. The basic expression of the degree of couplet is extended at different levels and at the same level to form a multi-element connection number, in order to set up a five-element connection number in relation to I-V grades evaluation standard commonly used in lake assessment. The discrepancy degree is expanded into partial identity in discrepancy, entirety discrepancy and partial contrary in discrepancy, this forms a multivariate connection number of identity, partial identity in discrepancy, entirety discrepancy, partial contrary in discrepancy and contrary. By introducing triangular fuzzy number the number of links to get the evaluation grade for a confidence interval was obtained, weight value calculated by weighted average method and finally got the evaluation grade as a confidence interval based on confidence level. The case study shows that the method presents the evaluating grade as a confidence interval which has advantages of high resolution and information utilization.

     Abstract:

We deal with the Camassa-Holm equation   possesses a global continuous semigroup of weak conservative solutions for initial data. The result is obtained by introducing a coordinate transformation into Lagrangian coordinates. To characterize conservative solutions it is necessary to include the energy density given by the positive Radon measure µ with . The total energy is preserved by the solution.

Innovation has significantly contributed to the transformation of organizations. The current research aims to determine the level innovation of communication and information technology that was employed by micro, small and medium sized corporations. The research respondents consisted of 100 micro, small and medium corporations, who were registered as active operated in the Industry, Trade and Cooperatives Office of Yogyakarta Municipality, Indonesia. The findings of this research demonstrated that micro, small and medium sized corporations innovated by employing communication and information technology in the operation of their businesses. The research discovered that 93% of the MSMEs (Micro, Small and Medium Enterprises) promoted their products using the internet, while 86% viewed innovation to be an important facet of their business. Furthermore, the smartphone was utilized by 100% of the MSMEs, to support the operations of their businesses.

The present experimental study aims at characterizing the mixing characteristics of subsonic elliptic and rectangular orifice jets (V_e = 51 m/s) in the presence of wall of different surface roughness, namely smooth, fine and coarse, placed parallel to the jet axis at the edge of the orifice exit. The wall of length 120 cm of different surface roughness was oriented either parallel to the minor axis plane or major axis plane if the orifice. The wall had a strong effect on the mixing characteristics of elliptic and rectangular jets. The centerline velocity measurement showed that the potential core of elliptic and rectangular orifice jets was around 3D_e and 3.5D_e. For both jets, all the wall configurations retarded the mixing of jet with the ambient fluid only in the characteristic decay zone but not in the core and fully developed zones. The level of mixing retardation was found to be maximum when wall was placed parallel to the major axis plane of the jet. The effect of wall on jet mixing was intense for rectangular jet compared to elliptic jet.

Mining assets are unrepeatable and an important source for the development of a country. Their industrial exploitation is based on mining, metallurgical, economic, environmental, and state social factors. Mining factors such as production capacities, mining costs and the realization of indicators of loss and dilution are the determinants of the success of a mining activity. The value of a mining project, which is based on limited reserves, is very sensitive to loss indicators and dilution, as each lost tonnage of minerals affects the value of the resources. In this article, we will discuss the degree of impact of the above factors, while paying attention to achieving the most optimal indicators of loss and dilution. In mining activities with limited reserves and where the value of a mineral tone extracted from the ground is high, is required to increase the extract / loss ratio and maintaining a fair ratio between the indicators of loss and dilution
