However, design codes have been slow to adopt provisions for the design of partially prestressed concrete because of concerns over fatigue and corrosion. The results of this study will be helpful to structural engineers designing new partially post-tensioned concrete structures or evaluating existing post-tensioned concrete structures that have suffered deterioration and/or damage. This objective was investigated through an experimental program, which included both individual strand testing and full- scale, post-tensioned beam specimens. The strand testing phase consisted of corroding samples to different amounts of section loss, and then testing them under cyclic loading until failure. The beam testing phase included 12 full-scale, post-tensioned beam specimens combining long-term static exposure testing with fatigue testing. Partially prestressed concrete offers several advantages over fully prestressed designs. The overall objective of this study was to determine the viability of partially post-tensioned concrete members in an aggressive environment, including the impact of cyclic loading.

Однако он также был выдающимся мыслителем и публицистом, который поднимал в своих произведениях и статьях важнейшие проблемы русского национального сознания, не потерявшие своей актуальности и в наши дни. Весь мир знает Ф. М. Достоевского (1821-1881) как великого романиста и классика русской литературы, создавшего такие бессмертные произведения, как «Братья Карамазовы», «Идиот», «Преступление и наказание», «Бесы».

|Metal Induced Crystallization and Polysilicon Thin Film Transistors. Novel technologies of crystallization and post-annealing Книга по Требованию Bo Z. |
A few technologies are presented in this monograph, which improve the quality of MIC polysilicon film and hence the performance of TFTs built on. Amelioration of MIC processes has been made to produce high performance polysilicon TFTs using solution based MIC (SMIC) and defined-grain MIC (DG-MIC) methods.

|Post-Solidarity and Postmodern Intergenerational Relation(ship)s. Changes in Patterns and Values of Contemporary Intergenerational Relation(ship)s Книга по Требованию Michael-David A.K. |
Bernardes has gone so far as to observe that the Modernist view that family and intergenerational relation(ship)s are dominated by one socially ‘normative’ model (i. e. , the enduring nuclear family) is an ‘oppressive practice. ’ I propose a construct of intergenerational relation(ship)s that goes beyond the Modernist paradigm asserted by the ‘solidarity perspective’ and that comprehends the Postmodern conceptualization of the “contemporary family as filled with doubt, ambivalence, and insecurity” (Stacey, 1991, p. 17). Modernist notions of the primacy and unity of the nuclear family and of the inviolate nature of intergenerational relation(ship)s perpetuated by such influential researchers and social-gerontological theorists as Bengtson and colleagues, I suggest, no longer sufficiently comprehend the lived experience of contemporary kin relation(ship)s.

|"Born in Africa but...". Women's poetry of post-Apartheid South Africa in English Книга по Требованию Isabelle V. |
The study itself is dedicated to South African post-Apartheid women' s poetry. While working with the primary texts, the poems themselves, the focus is on the different aspects of identity which portray the major topics of South African poetry at present. The second and main part of the study looks at the most prominent recurring themes of contemporary South African women' s poetry: • ethnic identity, identity within individual groups of society and the depiction of the relations between the ethnic groups, is treated in Chapter VI, • gender identity, a discussion of gender problems and womanhood and motherhood, treated in Chapter VII and • professional identity, being an artist, a woman poet, treated in Chapter VIII.

|A Reconsideration of Hobbes for Post-9/11 America. Hobbes for a Post 9/11 World Книга по Требованию |
If compatible with America' s traditions, Hobbes' s philosophy should be studied with the intent of using it to enhance and understand our security policies. Thomas Hobbes' s era and ours are quite different, but upon closer review the strife that seemingly characterizes the 21st century appears similar to conflicts during the 16th and 17th centuries in Europe and more specifically England. Hobbes argued that this similarity resides within human nature and our passions -- most importantly fear. Hobbes' s influence has waxed and waned in Western thought and once again due to the War on Terrorism it has reemerged.
