Abstract

The effective diffusivity of carbon dioxide and iodine through “G” tunnel tuff were determined using a steady-state method and an unsteady-state method respectively. Results show that the effective diffusivity of carbon dioxide and iodine through dry tuff increased with temperature. The effective diffusivity of carbon dioxide decreased as the moisture content of the “G” tunnel tuff increased. An emprical correlation was obtained to estimate the effective diffusivity of carbon dioxide as a function temperature and the percent saturation. Specific surface area and pore volume of tuff was determined using a mercury porosimeter. A scanning electron microscope was utilized to further characterize the porous structure of the tuff samples.

Abstract

The research reported is based on a study that compared two seminar/classroom software end-user-computing (EUC) training methods in terms of understanding outcomes. Understanding of the target software, IFPS, was measured in terms of architecture, function, and syntax. Results showed that for function understanding, construct-based training was superior. For syntax understanding, those with a high level of previous experience and low levels of 'crystallized' intelligence had the highest levels of understanding. There were also some near significant interactions between training methods and individual differences. Suggested directions for researchers and implications for practitioners are discussed. >

Abstract

Epithelial cell kinase (ECK) is a receptor protein tyrosine kinase, the role of which in melanoma biology is unclear. Here we studied the role of ECK during melanoma progression. ECK mRNA was overexpressed in virtually all melanoma lines tested, and levels were significantly higher in cell lines from distant metastases than primary melanomas; melanocytes were negative. Gene amplification was not detected in melanomas. Levels of ECK protein corresponded well with mRNA levels. B61 or LERK-1, recently identified as an ECK ligand, stimulated the growth of ECK-expressing melanoma cell lines, its first identified biological activity. Melanoma chemotaxis and chemoinvasion were not affected by B61. Growth of normal melanocytes was not affected. mRNA for B61 was detected in both melanoma cell lines and normal melanocytes. B61 was also identified by Western blotting and ECK binding activity with the use of a BIAcore binding assay in melanoma cell-conditioned media. These results suggest that B61 is an autocrine growth factor for melanomas but not normal melanocytes.

208. Urinary Hydroxyproline Excretion in Myelofibrosis

Author

Wang, Jen C., Aung, Maung K., and Tobin, Mark S.

Abstract

Urinary hydroxyproline measurements were performed in a group of health volunteers as well as patients with cancer and myelofibrosis. Patients in whom there was no metastatic involvement of bone marrow excreted an amount of hydroxyproline not different from that of the control group. Those who had marrow metastasis produced elevated levels of hydroxyproline; the highest excretions were observed when marrow fibrosis was associated with metastasis. These results contrasted with those observed in agnogenic myeloid metaplasia patients whose excretions were equivalent to the control group. The result suggests differences in the pathogenesis of myelofibrosis and a technique potentially useful for distinguishing between patients who may otherwise be diagnostic problems.

209. How I do it?: excision of neck lumps under local anaesthesia.

Abstract

Excisions of neck lesions under local anaesthesia are made technically more difficult by the injection of anaesthetic agent, causing the lesion to become less palpable. Pen marking the lesion can circumvent the problem; however, this marking often disappears after skin preparation. We describe a technique which abolishes this problem. [ABSTRACT FROM AUTHOR]

211. Action Research as a Proactive Research Method for Construction Engineering and Management.

Abstract

Academic research in applied disciplines such as construction engineering and management (CEM) has the dual mission of simultaneously contributing to the solution of practical problems and creating theoretical and conceptual knowledge. To do so, appropriate research approaches are needed. However, extant literature in the field has paid little attention to this issue and research methods used have been almost entirely either quantitative surveys or case studies. In this paper, action research (AR) is proposed as an answer to this knowledge gap. AR aims at building and testing theory within the context of solving an immediate practical problem in a real setting. The paper describes the underlying philosophy and application procedure of AR and highlights its strengths and weaknesses. Then, the applicability of the method to CEM is illustrated through a case study of improving access to information to support planning and decision making in a construction owner organization through designing and implementing a data warehouse. The findings indicate that AR is a reliable, structured, and rigorous research approach that is very useful for conducting applied research in construction and enabling academia to influence and improve construction industry practices. It can also effectively help to improve collaboration between academic researchers and industry practitioners in research and development projects. [ABSTRACT FROM AUTHOR]

212. The Importance of Learning Style in End-User Training.

Abstract

The importance of effective training in ensuring the success of end-user computing (EUC) has been emphasized by several researchers in information systems. A vast amount of evidence from research in related areas such as educational psychology suggests that individual differences such as reaming style may affect users learning about a new EUC software package. This article reports the findings of a series of studies that examine the influence of a novice's learning style in reaming typical EUC tools such as spreadsheets and electronic mail. A consistent pattern of findings emerges that indicates that learning modes is an important predictor of learning performance, both by itself and in interaction with training methods. The findings suggest that in the design of training, it is essential to match training methods to individual difference variables. Based on these findings, guidelines are recommended for IS professionals involved in EUC training and further research directions are discussed. [ABSTRACT FROM AUTHOR]

Abstract

Unlabelled: Coronary artery disease (CAD) is a major cause of death in patients with insulin-dependent diabetes mellitus. Qualitative changes in low density lipoprotein (LDL) and high density lipoprotein (HDL) are thought to be important for evaluating the risk for CAD. In the present study, we evaluated LDL particle size (LDL-size) by 2%-16% gradient gel electrophoresis, along with conventional lipids and apolipoproteins, in 23 children with IDDM (10 males and 13 females) and 27 nondiabetic controls (12 males and 15 females). The fractional and molar esterification rates (FER and MER) of cholesterol in plasma and HDL were also determined. Plasma levels of triglyceride were significantly lower in diabetic children than in controls. Plasma apoA-I and apoA-II levels in female diabetic children were significantly higher and lower than those in controls respectively. Plasma levels of HDL-cholesterol and the ratio of apoA-I to apoA-II were significantly higher in diabetic children than in controls. Other lipid and apolipoprotein parameters in diabetic children were similar to those in controls. LDL-size in diabetic children was significantly greater than that in controls. FERHDL, which reflects the particle size distribution of HDL, was significantly lower in diabetic children than in controls, which suggests that diabetic children had larger HDL particles.Conclusion: The qualitative and quantitative changes in LDL and HDL in diabetic children are similar to those associated with a reduced risk for CAD. Intensive insulin therapy in children may help preventing coronary heart disease in adulthood. [ABSTRACT FROM AUTHOR]
