Currently, the pleating technique is favored by famous fashion houses in world and Vietnam because of its beauty sophistication. This study aims to techniques, testing papers, several polyester fabrics form pleats under paper mold pressing manual heat-pressing method with three types heat-pressed equipment such as steam iron, oven, homemade heated box. One experiment results a parameter table a...

To confer hydrophobic properties to Kraft pulp, an environmentally friendly process using laccase and lauryl gallate (LG) was developed. This treatment resulted in paper with very high water-barrier properties. The loss of hydrophobicity after acetone Soxhlet extraction highlighted the key role of adsorption phenomena on the introduction of pulp properties. GC-FID analysis of the extraction sup...

The authors studied a cohort of 30,157 male pulp and paper workers in British Columbia, Canada. Of these, 20,373 worked in kraft mills only, 5,249 in sulfite mills only, and 4,535 in both kraft and sulfite mills. All workers with at least 1 year of employment on January 1, 1950, or thereafter until December 31, 1992, were studied. Standardized mortality ratios (SMRs) were used to compare the mo...

Kraft’s inequality [9] is essential for the classical theory of noiseless coding [1, 8]. In algorithmic information theory [5, 7, 2] one needs an extension of Kraft’s condition from finite sets to (infinite) recursively enumerable sets. This extension, known as Kraft-Chaitin Theorem, was obtained by Chaitin in his seminal paper [4] (see also, [3, 2], [10]). The aim of this note is to offer a si...

This paper describes our efforts focused at defining the formation of diphenylmethane moieties in lignin during conventional kraft and soda pulping conditions. This objective was realized by confirming, initially, the assignment of a P NMR signal as being due exclusively to the presence of phosphitylated diphenylmethane (DPM) phenolic hydroxyl groups. More specifically, softwood milled wood lig...
