The current resea.ch dea.s with the dispersion of fine settling pa.ticles in a.fluid flowing through a. icecovered cha.nel under the la.ina. flow condition. a. a.a.ytica. solution of the two-dimensiona. convection-diffusion equa.ion, ba.ed on the multi-sca.e homogeniza.ion technique, is obta.ned. To va.ida.e the current study, a.a.ytica. results for the dispersion coefficient a.e compa.ed with the a.a.la.le ea.lier resea.ch work. Moreover, the proposed a.a.ytica. solutions for mea. concentra.ion distributions of the tra.ers a.e compa.ed with the numerica. results obta.ned from the finite difference technique. From the industria. a.d environmenta. points of view, the vertica. concentra.ion distribution provides a.very significa.t informa.ion. The downstrea. evolution of the concentra.ion distribution a.so is shown for typica. time periods a. different va.ues of the settling velocity. The a.proa.h to the vertica. uniformity shows tha. it is too slow a.process in compa.ison to tha. of longitudina. norma.ity. It wa. found tha. settling velocities of pa.ticles disturb the vertica. uniformity a.d the centroid of the solute cloud rises due to the increa.e in settling velocity. Results illustra.e tha. in the downstrea. direction, the vertica. concentra.ion distribution increa.es nea. the bed surfa.e a.d it decrea.es in the proximity of the ice-covered surfa.e of the cha.nel with the increa.e of settling velocity, but the mea. concentra.ion of the solute increa.es. The current study ma. pla. a. importa.t role to understa.d the mecha.ism of the sedimenta.ion process in a.closed cha.nel system.

健康一直是全世界最重要的问题之一,这就是为什么它被联合国列为全球议程的优先事项的原因。联合国发起的千年发展目标(Millennium Development Goa.s)(4和5)和可持续发展目标(Susta.na.le Development Goa.s)(3)都反映的卫生议题在全球议程中的优先地位。为实现千年发展目标4和5中关于孕产妇和儿童健康的发展目标,可持续发展目标3已经设定了到2030年的新目标。多年来,孕产妇和儿童健康的发展目标仍然是孟加拉国等发展中国家的主要公共卫生问题。作为一个发展中国家,孟加拉国在卫生千年发展目标4和5面取得了显着进展。自从联合国的可持续发展目标实施以来,孟加拉国在孕产妇和儿童健康目标实现方面积极努力。然而,孟加拉国的医疗保健系统面临着多方面的挑战,因此可持续发展目标的实施并不如千年发展目标那么顺利。基于相关数据之上,本文分析了孟加拉国卫生相关千年发展目标过去取得的成就以及可持续发展目标在卫生部门的当前进展。它试图通过对过去千年发展目标和目前可持续发展目标的推进速度进行比较,来展示当前卫生部门尤其是妇幼卫生部门的不平衡进展。它还评估了孟加拉国这一令人不满意的进展背后的当前挑战。本文认为,社会经济不平等、医疗服务利用不足、现有医疗服务质量差、政治局势不稳定以及当前政策中的差距,是可持续发展目标3实施的主要障碍。最后,本文基于上述挑战,尝试性地提出了一些有助于决策者和可持续发展研究学者找出差距并解决这些问题的政策建议,以更好地实现联合国可持续发展目标3中的卫生治理目标。
