Abstract In this paper, acrylate-terminated polysiloxane was synthesised and used as raw materials for the synthesis of cationic core/shell polysiloxane acrylate emulsion, which was applied as binders in the pigment dyeing of cotton fabrics. The experimental results showed that: the cationic core/shell poly siloxane acrylate emulsion in this article is in nano size of 100nm. During the film formation of the emulsion, there are core-core and shell-shell fusion phenomena between the latex particles, and same poly siloxane chain aggregates on the surface of the film. When the emulsion is used in the pigment dyeing of cotton fabrics, the dyed cotton fabrics feel soft, and the soaping fastness and dry/wet rubbing fastness meet the national quality requirements, as soaping fastness can reach grade 4 ~ 5, dry rubbing fastness can reach grade 4 ~ 5, and wet rubbing fastness can reach grade 4.

Optimization And Performance

Abstract Air separation plants use centrifugal compressors where air and electrical energy are the only raw materials used in the production process. So energy costs play a crucial role and the compressors are heavily penalized when guaranteed performance levels are not achieved. In order to better generate performance, abradable coatings, previously used in the gas turbine industry, have been designed into turbocompressors. This paper will show the optimization and performance improvements of a new aluminium silicon-boron nitride material.

National Quality Award

Purpose – In recent decades, a framework for management performance has proven to be an important management practice for achieving organisational performance excellence. In this sense, the purpose of this paper is to analyse how a specific company manages to achieve performance excellence through the attainment of the Brazilian National Quality Award. Design/methodology/approach – The study adopts a case-based approach using a single unit of analysis that might be considered a revealing case. The company studied is one of the largest companies in the information and financial analysis sector in Latin America and is part of a major worldwide corporation. Semi-structured interviews with senior managers and document analysis were used for data collection, with content and inductive analysis performed a posteriori. Findings – The main results outline the approach adopted by the company for each performance excellence award criterion and highlight some of the relevant organisational practices, especially those related to the nature of the company’s businesses. The findings show that the top management has been an essential driving force in transforming the managers at all levels into agents of improvement at the studied company. Additional key points are the deployment of the company’s “shared values” throughout the company and the implementation of a medium- and long-term comprehensive strategic plan focused on the award criteria. The company’s strategic system has been a driving force of its success. Research limitations/implications – For a more extensive empirical validation, further replications using other samples are needed to ensure the external validity of these findings. Originality/value – This paper is one of the few published studies discussing business excellence in emerging economies, which is not observed very often in developing markets. In addition, the paper focuses on promoting a culture of quality, a less common phenomenon in the economies of developing countries than in those of developed nations. Finally, this paper may be useful for practitioners and academics interested in the subject of quality and performance excellence.

Gelcasting Process

A new tubular cathode support for Direct Ethanol Fuel Cell (DEFC) was prepared by the gelcasting process using mesocarbon microbead(MCMB) and graphite as the main raw materials. The effects of different graphite doping ratios on tensile strength, bending strength, crushing strength, volume resistivity and shrinkage rate for the prepared tubular cathode support were studied by experimental test. The result showed that the prepared tubular cathode support had very good comprehensive performance. The tubular cathode support with 10% graphite exhibits the best performance such as bending strength 25MPa and resistivity30µΩ•m, and it satisfied the DEFC cathode working conditions and performance requirements.

Degree Of Similarity

Biochemical diversity or polymorphism is the occurrence of varieties attributed to biochemical differences which are under genetic control. It has created a leeway for the genetic improvement of farm animals. This is because it can be used as a useful tool for the characterization of livestock breeds and population. This way, the degree of similarity or differences within and between breeds can be ascertained and this differences or similarity are important raw materials for genetic improvement of animals. Data obtained on gene frequencies and genotypes through polymorphism study makes it not only possible to compare the gene stocks of animals, the possible effects of the genes on reproductive and performance traits, but also study genetic variability under different environmental conditions of selection. This study was carried out to review haemoglobin (Hb) polymorphism in selected farm animals with the view of finding out the type of polymorphism observed by starch gel electrophoresis due to variation in the amino acid sequence in the polypeptide chains of Hb. The review showed clearly that there is a gene-controlled diversity in the different farm animals considered. This could serve as a reference point for future studies earmarked for the improvement of the animals possibly via marker-assisted selection.
