Tensile Strength Properties of Tropical Hardwoods in Structural Size Testing
In Malaysia, there is no research done on the tensile strength of structural size timber. The tension stress found in the Malaysian code of practice, MS 544: Part 2: 2001, was not determined directly and it was taken as 60% of the bending strength values of small clear specimens. This paper presents the results of the tensile test on structural size timber specimens from selected Malaysian Tropical hardwoods namely Kedondong (Canarium spp), Keruing (Dipterocarpus spp) and Bintangor (Calophyllum spp) under the strength group SG5. A special tensile grip was fabricated using the model suggested in ASTM D198 and the tests were also conducted according to ASTM D198. The tensile strength characteristics evaluated include tensile strength, modulus of elasticity and Poisson’s ratio, and the data were analyzed statistically. In this study it was found that the grade stresses for structural size specimens were higher than that published in the Malaysian code of practice.

Turkish Political Culture and Civil Society : an Unsettling Coupling?
This paper attempts to analyze Turkish politics in the post-1980 period with a special reference to the relationship among the state elites, political elites and societal actors and its impact on the constitution of civil society in Turkey. After the 1980 military intervention, the political and economic realms of Turkey witnessed a relative degree of liberalization through Uzal's neo-liberal policies. The January 24 economic decisions paved the way for economic liberalization as well as letting new economic and societal actors emerge. These new economic actors were different from the prevailing economic actors which used to enjoy having a considerable amount of opportunity spaces in the economic sphere. Together with the Uzal governments, Islamic segments started to become powerful in both political and economic realms. This paper analyses the chief traits of Turkish politics and economics and their impact upon civil society aftermath the 1980 coup in general, and the relationship and/or interaction among the state elites, political elites and societal actors in particular. The engagements of newly-emerging societal and economic actors into Turkish political scene and the challenge of these actors against the so-called 'Kemalist-Republican' elites are also illustrated in the paper. Moreover, state-Islam interaction, politics-Islam interaction as well as Kemalism-newly-emerging societal and economic actors interaction will be studied with a special emphasis to the post-1980 period. The major argument of the paper is that, in Turkey, both civil society issues and political issues reveal outcomes which are primarily shaped by the nature of the relationship between state elites and political elites in general and by Turkish political culture in particular.
