Macrosegregation during plane front directional solidification of Csl-1 wt. percent Tll alloy

Macrosegregation produced during vertical Bridgeman directional solidification of Csl-1 wt. pct. Tll in crucibles of varying diameter, from 0.5 to 2.0 cm, was examined. Gravity driven convection is present in the melt even in the smallest crucible diameter of 0.5 cm. Observed solutal profiles are in agreement with the analytical boundary layer model of Favier which describes macrosegregation in the presence of convection. The scintillation efficiency of Csl decreases along the specimen length as the thallium iodide content of the alloy increases

PENINGKATAN PEMBELAJARAN MATEMATIKA POKOK BAHASAN RELASI DAN FUNGSI PADA SISWA KELAS X KL SMK NEGERI 1 SITUBONDO DENGAN MENGGUNAKAN METODE STAD

This type of research is classroom action research. The subjects of this research were 38 students of Class X KL SMK Negeri 1 Situbondo, Situbondo Regency. The purpose of this research is to describe the process of learning mathematics using the STAD method on the subject of Relations and Functions. Data collection tools and methods used in this research were tests, observations, and questionnaires. The results of this study 80% of students are happy about cooperative skills, and 75.5% argue that the device used is new. In addition, students' responses about process skills 82.6% were happy and 72.2% thought that the process skills used were relatively new. From these data shows that students like to be involved in learning using cooperative skills and process skills, especially in the process of observing skills where the opinions of students feel happy in doing observations by 95.7%.   Keyword: STAD, student achievement, cooperative skills, process skills, relations and function

The concepts and applications of Computer Aided Architectural Design (CAAD) have a predominant presence and impacts on human innovation and creativity. ASCAAD society invites academics, researchers and professionals interested in CAAD concepts, practical impacts on human innovation and traditional design thinking, products, processes or organizations to join and contribute to the debate on learned lessons from the past, present and potential future impacts of present and future CAAD on innovation

Farmers’ Perception of Water Quality and Risks in the Mashavera River Basin, Georgia: Analyzing the Vulnerability of the Social-Ecological System through Community Perceptions

Competing natural resources usage that leads to dramatic land use changes can threaten the balance of a social-ecological system. When this is the case, communities are directly exposed to the negative consequences of those land use changes. The Mashavera River Basin is considered one of the hotspots of environmental pollution in Georgia. This is of importance for public health because the food production from this basin meets a substantial proportion of the country’s food demand. The farmers’ perception of the water quality and their perceived risks to the economy, health, and lifestyle reflect the status of the environmental and social conditions. The inclusion of farmers’ risk perceptions is an important stage of water quality governance that could enable active civic participation. The approach of this research study was the convergence model in the triangular design of the mixed method approach. As part of the social data, the research study was conducted with a survey of 177 households, for which agriculture was either a main or partial source of income. A few focus group discussions were also conducted. A binary logistic regression analysis was employed as the main method for the analysis. The results from the pollution load index (PLI) were used as the supportive data to verify some geospatial hypotheses. We found that aesthetic attributes (i.e., color changes observed in the river) and the source of the water contamination (i.e., mining sites) were the main predictor variables for a perceived risk to water quality, health, and livelihoods. The people who work in agriculture as the main income source had more concern about their ability to sell their agricultural products as a result of water contamination in the river, compared with people for whom agriculture is a secondary source of income or for self-consumption. Age, amount of land, years of agricultural experience, and the source of water supply for agriculture did not have a significant effect on any of the risk perception or water quality perception models. The results indicate that the health risk is perceived more strongly in areas with more heavily contaminated water compared to less polluted areas. We propose that conducting a public risk perception assessment is an ideal means to detect people’s concerns regarding water quality governance for future risk analysis in Georgia. Another recommendation of this study is an integrated model of risk assessment that combines the results from a public risk perception assessment and a technical assessment. The benefits of such an integrated assessment include finding new hazard-sensitive areas for further analysis, the possibility to cross-check data for verification, communal communication of hazardous conditions by utilizing local knowledge, and the direct participation of the community in monitoring risks
