DHAKA Mike Gesicki Dolphins Jersey , March 8 (Xinhua) -- Despite gender inequalities still existing in the country, there is progress being made in many areas of the wellbeing of Bangladesh women.
Women's roles in Bangladesh are improving through the efforts of the women themselves and the broader society.
For the continued development of women, Prime Minister Sheikh Hasina's government has taken various measures, including adopting a female development policy, expansion of women's work areas, bringing poor and distressed women under social safety networks and empowering all levels of women.
Hasina at a program recently mentioned that the prime minister, the deputy leader of the house, the opposition leader, the speaker and a number of ministers are women in Bangladesh now, which is indeed a rare example.
"For the first time we've appointed a female secretary, female judges and female police officers, and they are performing excellently in their jobs."
She also referred to the increase in maternity leave to six months, and the establishment of daycare centers to help working mothers, as well as mentioning that the mother's name was now mandatory in any official document.
She went on to refer to the enactment of the Family Violence (prevention and protection) Act, Child Marriage Prevention Act, the setting up of eight hostels for working women, and a community clinic for rural women.
Female leaders say that without the active participation of more women and the incorporation of more women's perspective at all levels of decision-making, the goals of equality, development and peace cannot be achieved.
Parveen Sultana Jhuma, general secretary of Bangladesh Nari Sangbadik Kendra (BNSK), a center for female journalists in Bangladesh, stressed the need for ensuring the equal rights of men and women through law and other appropriate means.
"Women still do not enjoy the same legal status and rights as men in every matter in Bangladesh," she said.
She further said women have still been denied their due rights in some matters spanning religious and social customs.
Factors influences fatigue crack propagation life
The modeling of interaction effects requires consideration of crack-tip plasticity and its subsequent influence. In metals of all types, cracks will remain closed or partially closed for a portion of the applied cyclic load as a consequence of plastically deformed material left in the wake of the growing crack. Under cyclic loading, crack growth will occur during the loading portion of the cycle. Given that a plastic zone exists at the crack tip prior to crack extension, as the material at the crack tip separates, the newly formed crack surfaces will exhibit a layer of plastically deformed material along the newly formed crack faces. Subsequent unloading will compress this plastically deformed material, closing the crack while the applied stress remains tensile. This phenomenon is known as plasticity-induced fatigue crack closure and was first discussed by Ether." Discussion to this point has been limited to the growth of thmugb-thickness cracks under mode I loading. While mode I loading is often dominant, under the most general circum-stances the applied cyclic loads will generate stress intensity factor ranges AK AK, , and OK , at the crack tip, and mixed-mode fatigue crack growth must be considered. Modeling methodologies for mixed-mode fatigue c rack growth are discussed in Refs. 34 and 35. In addition, fatigue cracks in machine elements and structures are often not through-thickness cracks but rather surface cracks that extend partially through the thickness. Such surface cracks are often semielliptical in shape and the analysis of these cracks is considerably more complicated. Information regarding surface cracks may be found in Refs. 4 and 29
Research has suggested that when fatigue cracks are small, crack growth rates are larger than would be predicted using Eq. (15) for a given 4K36 Small-crack behavior is often important, as a significant portion of the fatigue life may be spent in the small-crack regime
The fatigue crack propagation life will also be influenced by the presence of residual stresses such as might exist as a consequence of welding, heat treatment, carburizing, grinding, or shotpeening. Compressive residual stresses are beneficial, decreasing the rate of fatigue crack growth and increasing propagation life. While approximate methodologies exist for incorporating the effects of residual stress within fatigue crack growth predictions," residual stress distributions are often difficult to characterize. Reasonable design estimates for the fatigue crack propagation life may be obtained using Eq. (17). However, the many uncertainties typically associated with fatigue life predictions emphasize the essential requirement to conduct full-scale fatigue tests to provide acceptable reliabtily.

BEIJING, March 12 (Xinhua) -- For 26-year-old iPad addict Zhou Wen, going to work is a lot like more play on his beloved device.
Though employed by textile producer the Ruyi Group, Zhou has never used a sewing needle. His job is to drive a battery-powered car around a new Ruyi plant in northwest China to locations shown on the map on his iPad and operate machines there following instructions on the screen.
""It is like a game, with new quests every day,"" Zhou said.
