phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
This paper presents an experiment in which two different fish culture system types were evaluated for the short-term commercial of fingerlings Clarias gariepinus maintained at half recommended stocking rate; 82.5/m3 2 m3 water volume indoor blue fiber-glass tanks (IFT) and outdoor black plastic (OPT). The research objectives to assess suitability viability tanks. Initial mean body weight graded...
The majority of paper-based microfluidic devices were produced by patterning hydrophobic zones via photoresist or wax. Others were created by cutting paper using a laser. We present a fabrication method by craft-cutting and lamination, in a way similar to making an identification card. The method employs a digital craft cutter and roll laminator to produce laminated paper-based analytical devic...
this dissertation has six chapter and tree appendices. chapter 1 introduces the thesis proposal including description of problem, key questions, hypothesis, backgrounds and review of literature, research objectives, methodology and theoretical concepts (key terms) taken the literature and facilitate an understanding of national security, national interest and turkish- israeli relations concepts...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
A finite element model is presented to simulate chip breaking when orthogonal turning medium carbon steel with a grooved cutting tool is used. The chip formation, chip breaking, cutting force, stress, strain and temperature are simulated by the thermo-elastic-plastic finite element method, using commercial finite element software. The cutting process is simulated from the initial to the steady-...
The amount of water supply in Japan was 16 billion ton as of 1989. Water from rivers and other sources is purified, sterilized and then supplied to the residents through conduits. When conduits are accidentally damaged, they must be repaired by the workers of the Waterworks Bureau of the local government. In this task, the workers are exposed to airborne dust which develops while digging and fi...
This paper reveals a study on air pollution process over North China, applying remote sensing technology, using satellite observation and in situ measurements during the twenty-first Asia-Pacific Economic Cooperation (APEC) meeting, which was held in Beijing between 6 and 12 November when the clear weather was called “APEC-Blue”. In the meantime, pollutants concentrations including PM2.5 and PM...
Many manufacturing defects could be seen in cylindrical turning. Some of these defects are: elastic deformation of work-piece, nonlinear backlash of cutting set – machine – workpiece, unknown geometry of untreated part, thermal deformations, vibration of set and machine. Deflection of workpiece under cutting forces will cause different levels of processing of workpiece 1 . Nonlinear backlash of...
INTRODUCTION AND OBJECTIVES In order to ensure food safety, food businesses in Europe must comply with national as well as Europe-wide legal hygienic requirements and regulations. For years, the use of plastic as a cutting surface was recommended over wood, as wood was shown to have negative reviews. The main arguments against wood are that it is porous, gets cut easily, and that difficult-to-e...
