The tension–tension fatigue behaviour of woven fabric composites was investigated in the on-axis and off-axis directions. Similar to the static tensile properties of woven fabric composites, the tension–tension fatigue behaviour of woven fabric composites was also observed to be anisotropic. The fatigue damage development in both the directions was studied using scanning electron microscopy and acoustic emission techniques. The influence of the applied fatigue frequency and the fatigue stress ratio in both the directions was investigated. At a fatigue frequency of 5 Hz, the hysteresis heating will occur more severely in the off-axis Asian Fit Oakley Dark Blue Lens Coffee Frame
direction than in the on-axis direction. Increasing fatigue stress ratio will lead to a lower hysteresis heating.
A content analysis of the Asian Fit Oakley Multicolor Lens Black Frame
textbooks used in the Dutch early childhood teacher education shows clear inconsistencies with the intended curriculum. Neither the content standards found in the professional profile for teachers nor the content standards from the educational profile of their training courses are adequately covered in the books. Whilst they pay considerable attention to the teacher's educational duties, other tasks outside the primary work process are either dealt with in much less detail or ignored altogether, including the need for strategic planning, for reflection and evaluation, for the development of educational policy, and for co-operation and liaison with colleagues from other disciplines.
