This study investigates the relationship between KM enablers and the KM performance in the Malaysian public sector. Five main independent variables of KM enablers; organizational culture, organizational structure, technology, people and political influence were tested against KM performance using structural equation modeling (SEM). Five hypotheses were tested on the relationship between KM enablers and KM performance. The sampling population of this study was Ministry of Natural Resources and Environment (NRE), Malaysia. The result confirmed that organizational culture, organizational structure, technology and people are the distinct constructs for KM enablers. The hypothesis testing indicates that there is a significant relationship between KM enablers and KM performance. The result indicates that Malaysian public sector should cultivate on KM enablers in order to implement effective KM. © Springer International Publishing Switzerland 2015. Source

Mutations of the WT1 gene have been reported as the most common abnormality after NPM1 and FLT3 gene mutations in acute myeloid leukemia (AML), while KIT mutations are predominantly found in core-binding factor (CBF) AMLs. We report for the first time the prevalence and distribution patterns of WT1 and KIT mutations in an Indian population of 150. Overall, 10 (6.7%) and four (2.7%) of the cases had WT1 and KIT mutations, respectively. Of the six mutations observed in exon 7, five were frameshift while the remaining one case showed a substitution mutation. In contrast to exon 7, no frameshift mutation was detected in exon 9, where all mutations were substitution mutations. Interestingly, we observed a novel mutation in exon 8 of the KIT gene resulting from the deletion of nine nucleotides and insertion of three nucleotides affecting the extracellular domain of the KIT receptor, while Asp816Tyr and Asp816His were commonly found in exon 17 of the KIT gene. The WT1 mutation was more prevalent in normal karyotype AML while KIT was associated with t(8;21). With respect to FLT3 and NPM1 mutations, WT1 was more predominant in FLT3 positive cases and less in NPM1 mutation cases, while no KIT mutation was found in FLT3/NPM1 positive cases. © 2011 Informa UK, Ltd.

A microdeformation of a simple polymer blend of polypropylene (PP) and ethylene butene rubber (EBR) was investigated in this study. Injection moldinginduced morphology close to the surface was analyzed by transmission electron microscope, polarizing optical microscope, and Fourier transform IR spectroscopy. Breakup and coalescence of EBR particles scarcely occurred during the injection process. The EBR particles near the surface were observed as continuous fibers and were gradually changing to the ellipsoidal shape in the depth direction. The morphology in an injection molded specimen was related to depth profiles of mechanical factors, which were microhardness and shear stress measured by a Vickers and a Knoop microindenter and "Surface and Interface Cutting Analysis System," respectively. Crystal structure of PP matrix affected to the microdeformation more strongly than that of EBR phase. The large oriented EBR domains disconnected continuity of the PP matrix and acted as a weak layer in the specimens. Finally, cohesive fracture occurred in the peel test of painted PP/EBR was discussed from a microdeformation point of view. © 2010 Wiley Periodicals, Inc. Source

Biaxially oriented polypropylene (BOPP) film accounts for a large amount of polypropylene since it is well suited for food packaging films or industrial films, because of its high performance in terms of mechanical and optical properties. Recently machine speed has been increasing to obtain higher production rate and film thickness has become thinner to reduce the environmental load. To meet the demands, many researchers have been investigating stretchability of PP by connecting the stretching force at the yield point and crystalline structure. Many other studies have been conducted regarding the surface structure of BOPP. Although there were some cases that crater-like film surface roughness was formed on BOPP films, the formation mechanism of craters has not been clarified. In this report, new hypothesis of the crater-like film surface roughness formation mechanism is proposed by observing the transformation of crater from sheet to BOPP film and by investigating the relationship between the stress-strain curve and surface roughness change. © 2011 Wiley Periodicals, Inc.

Biaxially oriented polypropylene films are widely used for food packaging and industrial films. Recently, machine speed has been increasing in order to obtain higher production rate, and film thickness has become thinner to reduce the environmental load. The customers' requirements for better production ability and thinner films have been becoming more demanding, but their demands are not always met because of lack of film stretchability in the final product. To meet the demands, research on stretchability has been conducted with the goal of finding the optimum polypropylene molecular structure for developing a new product by analyzing stretching force-strain data using a table tenter, which was thought to be the parameter of stretchability. It was found that low crystallinity and wide molecular weight distribution were effective in improving the stretchability from the table tenter test. By running the test with a sequential and biaxially oriented stretching machine, it was verified that samples produced by the above designed polymer indicated good thickness uniformity, which was considered to be the barometer of stretchability. Furthermore, it was concluded that analyzing the stretching force-strain data obtained from a table tenter is a good method to predict machine speed and film thickness. © 2012 Society of Plastics Engineers.
