    The thesis includes a literature survey of small hydraulic turbines, incorporating a historical review. The possible role of "micro hydros" in generating power in various parts of the world, and particularly in Iran, is discussed. The theory of turbo machinery, particularly with regard to axial flow turbines, is presented next. This is followed by some details on the design of guide vanes, runner blades and draft tube of axial flow turbines, these components being usually regarded as areas which have major impact on the performance of hydraulic turbines. The next chapter gives the details of the test circuit that was constructed. This could provide water volume flow rates of up to 0.15 m3/s at heads of up 25m. The two dynamometers that were used could adsorb pores to up to 25 kw and 50 kw respectively. An existing micro-turbine, the Agnew turbine, was selected for examination and possible improvement. The first possible improvement was the introduction of guide vanes upstream of the turbine runner (this inclusion necessitated a second support for the main shaft). It was found that this gave significant improvements - efficiency raised by over 20% in some cases. The domain of high efficiency working was considerably extended. It was observed that instability (with fall in power output) could occur after a period of running. This seemed to be associated with an accumulation of air bubbles at the highest point in the casing of the machine. Introduction of a vent from this point was found to relieve this problem and ensure stable operation

    In spite of the long-term existence of joint committees, injury rates appear to be increasing in the healthcare sector. The purpose of this study was to deliver and evaluate a province-wide joint committee (JC) education program for healthcare institutions BC. The joint committee education program was designed with input from labour and management representatives and expert advice from compensation, union, and human resources consultants. The training program was designed to: 1) ensure that committee members fully understood their roles and responsibilities as outlined under the Workers' Compensation Act and Regulations, 2) increase the problem solving skills of committee members, 3) improve the committee's ability in identifying and resolving health and safety concerns in their workplace. Between June and December 2000, 1,206 JC members, (employed at 262 different healthcare facilities), were trained. An evaluation survey, designed as a retrospective before and after study, to evaluate whether the JC training sessions had produced changes in committee functioning was conducted from 7 to 15 months after the training (during the period July 2001 to September 2001) by two trained telephone interviewers. While the level of JC functioning was quite high most institutions prior to training the evaluation survey found large and statistically significant improvements in JC functioning. A 39.5% increase in the proportion of respondents reporting “high” marks for JC effectiveness in identifying hazards and an increase of 50% reporting “high” marks for understanding the JCs role were observed. Increases in the proportion of respondents reporting “high” marks for accuracy of JC minutes, specificity of recommendations, and perhaps most importantly, degrees of cooperation among JC members were in the 20 percent range. IN conclusion this province-wide training of JC members in healthcare institutions increased the functioning of JCs in key areas

    The Drosophila protocadherin Fat (Ft) regulates growth, planar cell polarity (PCP) and proximodistal patterning. A key downstream component of Ft signaling is the atypical myosin Dachs (D). Multiple regions of the intracellular domain of Ft have been implicated in regulating growth and PCP but how Ft regulates D is not known. Mutations in Fbxl7, which encodes an F-box protein, result in tissue overgrowth and abnormalities in proximodistal patterning that phenocopy deleting a specific portion of the intracellular domain (ICD) of Ft that regulates both growth and PCP. Fbxl7 binds to this same portion of the Ft ICD, co-localizes with Ft to the proximal edge of cells and regulates the levels and asymmetry of D at the apical membrane. Fbxl7 can also regulate the trafficking of proteins between the apical membrane and intracellular vesicles. Thus Fbxl7 functions in a subset of pathways downstream of Ft and links Ft to D localization

    The objective of this research is to analyze the differences and the similarity of The Break Subtype of Affect-H in grammatical and semantical construction. This research use descriptive qualitative method. Primary data are the data in English and Buginese. To collect the data in English the researcher use C Corpus of Contemporary American English (COCA) and to collect data in Buginese language, the researcher recorded some native speakers of Buginese while using the break verbs in Buginese language. The secondary data are the data that were taken from journals, e-books, and articles. The collected data were analyzed by using Dixon’s theory of Break Subtype of Affect-H. The result of this research shows that there are 14 words in Buginese that are identical with the “Break” verb. They are mappakkasolang, ma’jemmu’, mapperra’, maruttung, massope/makkape’, mappue’, mappacippe, mappareppa’, malleppoang, mappa’bettu, mappaleppo’, mappaddempung, and ma’bettu. Construction I of break verb have the same meaning as construction II of mappakkasolang verb. They both means that someone break something by using another instrument. Construction II of break verb and mappakkasolang verb have different meanings. The sentence in Buginese means that someone break something on the table, but no conclusion can be taken about how someone broke the thing. As for the sentence in English it is obvious that someone accidentally put his/her nail inside a piece of wood and break it. Construction III of break verb is applicable but in the other hand, construction III of mappakkasolang verb is not a common way of saying that something is broken because another thing accidentally break it, as in Buginese sentence the role of breaking something is usually done by human, animals, disaster, or weather
