三类硬磁畴畴壁结构分析

实验研究了硬磁畴在不同温度下的静态性质，发现具有相同数目ＶＢＬ的硬碰畴在不同温度下的存在形式不一定相同，从而揭示了三类硬磁畴畴壁结构的一致性，证明了直流偏场作用下硬磁畴缩灭时ＶＢＬ间的平衡间距随温度的升高而增大。

Availability and Equality of Health Services: The Reduction of the Influence of Social Class on Obstetric Health Behavior in Northern Bangladesh

The present study attempts to examine the influence of social class (in terms of educational qualification, the occupation of the husband and monthly family income of the respondents) on obstetric health behavior (in terms of antenatal care or ANC visits, the intake of iron tablets, tetanus toxoid vaccination of mother, types of birth attendant, sources of information about obstetric health) in some suburban places of northern Bangladesh. Mix methods have been executed to conduct the present study. A total of one hundred and twenty-five (125) women who gave birth within the last two years have been selected through purposive sampling. Besides ten (10) case studies and five (5) key informants analysis have been performed in this study. As all the variables;both dependent and independent;used in this study are categorical, the Chi-square test has been used to assess the relationship between social class and obstetric health behavior. In this study, a significant association has been found between taking of iron tablets and occupation of the husband (P = 0.026);taking of iron tablets and educational qualification (P = 0.029);vaccination of mother (TT) and educational qualification (P = 0.004), whereas the association of other variables regarding social class and obstetric health behavior has been found insignificant. So the present study shows that the influence of social class on obstetric health behavior has been significantly reduced. It is evidenced that nowadays the effect of social class on obstetric health behavior has significantly faded by the availability, equality-based health services, and services through satellite clinics in the study area. Stakeholders and concerned authorities should give top priority to the findings while developing strategies to improve the condition of maternal health of Bangladesh to acquire the aims of reducing maternal mortality to less than 70 deaths per 100,000 live births.

苯并[a]芘生物标志物3-羟基苯并[a]芘研究进展

苯并[a]芘(B[a]P)是卷烟烟气中的重要有害成分,其在人体内产生的代谢物3-羟基苯并[a]芘(3-OHB[a]P),可作为B[a]P接触生物标志物用于区分不同暴露剂量人群(如吸烟者和非吸烟者,职业暴露和普通人群)及预测可能的作用机制。本文对B[a]P的危害性、3-OHB[a]P来源及检测方法进行了综述;并从3-OHB[a]P研究存在的问题和现状出发,对其在感受烟气和普通人群中进行生物监测的应用进行了展望。
