The aim of this research was to improve the durable press finish process on cotton fabric with non-formaldehyde finishing agents. The mercerization of cotton fabric was carried out by 30 Be’ NoOH at 20 C before finishing. The mercerized fabric was finished by padding in the mixture of 4% (w/v) BTCA 0.4% (w/v) chitosam and 6% (w/v) sodium hypophosphite then dried at 85 C for 5 min. The treated fabric was cured at 180 C for 3 min. The finished fabric showed wrinkle recovery angle at 262  tensile strength at 281 N and elongation at break at 34.8 mm. The result showed that the combination of mercerization process and chitosan supported the crosslinking of BTCA on cotton fabric and reduced the loss of tensile strength of finished fabric.

This paper presents the analysis of electric field by using FEMLAB simulation tool to find the optimal electric field and component designs. Design of Cable terminator is tested by finding PD Value with IEC standard. This paper also proposes the electric stress when we design the cable terminator includes SF6 insulator. The modeling design is very useful for High Voltage engineers to find the optimal solution of Cable terminator design.

English is now regarded as an important medium for international communication among people all around the world in politics education economics and tourism. Vocabulary is an important fundamental element for learning English. It is necessary for students to have lexical knowledge to develop their language proficiencies and communicative competence but Thai undergraduate students are not generally equipped with sufficient lexical items. The concepts and pedagogical implications of the lexical-based learning approach are proposed. It is hoped that this article will be highly beneficial to syllabus design and language instruction in the near future.

This article presents The Analysis for high-Voltage Electric Stress in Lp and Ls coils of Tesla Transformer for studying the efficiency design. The tesla transformer is designed at 350kV rating Voltage and 120 kHz resonant frequency. The effect of high voltage when we designed the coil has impact to Electric Stress between primary and secondary coil because the tesla transformer uses air core. The insulator of coil also has problem on the reason as flashover on the 2 coils. The best dimension among coil has to present in this paper by using optimal mathematical solution. The simulation results show performance of the solution and ensure the methodology with positive way.

This research studies the potential for using classified fly ash from Mae Moh power plant in Thailand as a pozzolanic material. Three different fly ash finenesses viz. coarse Original Fly Ash (OFA) Medium Fly Ash (MFA) and Fine Fly Ash (FFA) were used for the study. Ordinary Portland Cement (OPC) was partially replaced with fly ash at 20 and 40% by weight of binder. The water to binder ratio was kept constant at 0.5 and the flow of mortar was maintained at 110±5% with the aid of superplasticizer (SP). Compressive strength carbonation depth and porosity test of mortars were determined. FFA has a high potential to be used as a good pozzolanic material. The use of FFA produces mortars with good strength and low porosity. The resistance to carbonation of mortar improves with partial replacement of FFA in comparison with the normal coarse fly ash. The use of FFA results in a strong and dense mortar which is due to better dispersion and filling effect as well as an increase in the pozzolanic reaction.
