Aging characteristics of glass fabric/phenolic composites for tilting train subjected to combined environmental aging factors were investigated. A 2.5KW accelerated aging tester with a xenon-arc lamp was used to provide environmental aging factors such as temperature, moisture, and ultraviolet. A series of aging tests were conducted up to 3000 hours and several types of specimens were prepared along the warp direction and the fill direction. Mechanical degradations for tensile, flexural, and shear properties were evaluated as a function of exposure times through a material testing system. Thermal analysis properties such as storage shear modulus, loss shear modulus, and tan 3 were measured through a dynamic mechanical analyzer. Finally exposed surfaces of the composites were examined using a scanning electron microscope. According to the experimental results, mechanical properties and thermal analysis properties of glass fabric/phenolic composites were found to be slightly degraded as a function of exposure times due to combined environmental effects.

In 1536, two Piedmontese merchants set up workshops in Lyons, and Henri IV encourged further development later in the 16th century. The development of Lyons as a centre of the silk weaving industry was helped by the perfection of drawloom weaving technique there in 1605 by Claude Dangon. In the 17th century, the French silk industry could finally compete with the dominance of the Italian silk trade. The French silk industry was promoted in the mid-17th century under Louis XIV's minister Colbert. In 1667, he published an ordinance creating La Grande Fabrique, a corporation for craftsmen within the silk industry, and Lyons became the undisputed French silk capital. Under Louis X IV, France was becoming the dominant force in Europe in matters of fashion and style. The major innovation of weaving was the Jacquard head attachment, which provided a mechanical means of raising warp threads by a series of punched cards. The are nouveau style did not have much impact on French silk design at the end of the century. Silk manufacturers began to collaborate with haute-couture designers such as the House of Worth. This collaboration with the burgeoning Paris haute-couture industry continued into the 20th century and safeguarded the future production of silk textiles in France.

This study aims to analyze the influence of apparatus resources, organizational commitment, internal control on the accountability of village fund allocations with the level of education as a moderating. Accountability analysis of village fund allocation is carried out at every stage of planning, implementation stage, administration stage, reporting stage, and accountability stage. The study was conducted in 18 villages in Undaan District, Kudus Regency - Indonesia, with a total sample of 115 village officials. Structural Equation Model analysis techniques with Warp Partial Least Square were used to test the research hypotheses. The results showed that apparatus resources, organizational commitment, and internal control had a positive effect on the accountability of village fund allocations. The level of education strengthens the influence of apparatus resources on the accountability of village fund allocations. The findings of the study further prove that commitment has positive implications for achieving accountability. It means that the higher the commitment made by the government apparatus, the better and higher the effect on accountability in managing public funds. With an ethical commitment of the government apparatus in managing the budget, the use of funds can be in accordance with the planning and designation so that goals can be achieved.

The purpose of this study is to investigate the contiguity of social capital and competence on business performance moderating by government policy. A total sample of 225 Village Credit Institution (LPDs) managers in Bali, the hypothesis is examined using the WarpPLS analysis. The findings reveal that social capital has an important role in enhancing performance, Competence is also an important factor for managers because it can intensify performance. Social capital is largely related to the recognition of society regarding the credibility of the managers, while competence emphasizes the ability of the managers to manage the organization. Government policy must be viewed as a regulation that is able to help improve performance. However, the public policies issued by the government are still unable to help improve social capital and competence. Thus, to create public policies that are able to improve the competence and social capital, a further examination into the variables must be conducted. The findings suggest that two-way communication must be developed and synergy between the government and organizations to create opportunities and overcome the increasingly complex business challenges. The results emphasized the importance of social capital in enhancing business performance. In addition, the role of competence is of equal importance to enhance business performance.

In this study, Two types of polyester fabrics were hydrolysed with NaOH using the CDR m/c of pad-steam type and the Sofleena m/c of liquor-flow type to determine the alkali hydrolysis properties of polyester fabrics. The results were as follows: Under the same conditions, the weight loss of charmeuse was about 0.5% and 2~3% higher than that of pebble with CDR m/c and with Sofleena m/c, respectively. The weft density of pebble decreased about 14picks/inch with CDR m/c and 3picks/inch with Sofleena m/c comparing to the untreated sample at 18% of weight loss, while the weft density of charmeuse decreased about 5picks/inch with CDR m/c and 2picks/inch with Sofleena m/c at 20% of weight toss. K/S value decreased almost identically within about 11% weight loss of pebble and 8% of charmeuse processed with both CDR and Sofleena. However, in the above these weight losses, K/S value of the fabrics processed with Sofleena was higher than that of fabrics processed with CDR. The bending rigidity of warp direction of the fabrics ($2{\times}10^{-2}gf.cm^2 /cm$ higher for charmeuse and ($7{\times}10^{-3}gf.cm^2 /cm$ higher for pebble) processed with CDR m/c was higher than that of the fabrics processed with Sofleena m/c.
