BACKGROUND: According to the fact that women account for the highest rate of victims of mental health loss during disasters, prioritization of their requirements is of remarkable signifi cance. Therefore, the present study was carried out with the aim to prioritize factors related to women's mental health during an earthquake. METHODS: This study was conducted using the Delphi method in 2017. Participants consisted of experts including psychologists, counselors and psychiatrists, social medicine specialists, and psychiatric-mental health nurses with experience in service and disaster awareness, especially earthquake. They were selected using purposive and snowball sampling methods. The Delphi method was used in 2 rounds with 21 components and the fi nal attendance of 19 participants and the collective agreement of 75%. RESULTS: Of the 21 factors related to women's mental health during the earthquake, the following components were, respectively, preferred by the participants: psychological well-being training, group relationships and support of women in emergency situations, fair treatment in the provision of rights and services to women, crisis awareness and management of behavior and diffi cult conditions, and social security during disasters with the total mean standard deviation (SD) of 13.4 (2.4), 13.0 (2.4), 12.7 (2.5), 12.5 (2.4), and 12.3 (2.2), respectively. CONCLUSION: Training in the fi eld of psychology and disasters, and social and cultural factors were prioritized among factors related to women's mental health during an earthquake. Therefore, the results of this study can be applied by the planners and executives of mental health, women and disasters, and the women's community itself.

鉴于微泡钻井液在衰竭油气藏钻井中的成功应用,通过实验测试和数据分析研究了微泡钻井液的流变性及稳定性。配制了一种典型的微泡钻井液,在不同温度下对其黏度进行测试,分别采用幂律模型、宾汉塑性模型和Herschel-Bulkley模型对测试数据进行了拟合,发现Herschel-Bulkley模型更能准确描述不同温度下微泡形成前后钻井液的流变性。根据Herschel-Bulkley模型拟合结果,温度升高会提高微泡钻井液的剪切稀释程度,微泡形成后钻井液的静切力和井眼净化能力提高,且在高温下微泡钻井液性能不会明显减弱。低剪切速率下微泡钻井液具有较高的黏度,可以保证良好的孔隙堵塞效果。微泡尺寸增长速率及静态析出实验中液体析出速率可作为评价微泡稳定性的指标:微泡尺寸随时间增加增长缓慢且寿命较长,静态析出实验中液体析出速率低,说明微泡钻井液具有良好的稳定性。

Genetic variability and divergence among natural populations of Jaculus jaculus and J. orientalis in Tunisia were examined by electrophoretic analysis of 16 enzymatic proteins encoded by 23 genetic loci. Low levels of genetic variability were found among populations of both species in comparison to those of other rodent and mammal species of which data are available. In J. jaculus populations, the mean level of observed heterozygosity （Hobs） ranged from 0.08 to 0.19, while the mean percentage of polymorphic loci （P） ranged from 26.2% to 45.2% and the mean number of alleles per locus （A） ranged from 1.1 to 1.4. Nevertheless, the mean values were 0.10 to 0.15, 29.3% to 44.1% and 1.1 to 1.7, respectively, for J. orientalis. In addition, populations of the two species have revealed a lower degree of genetic differentiation （Fst=0.0017 for J. jaculus and 0.0019 for J. orientalis）. Moreover, Fst was 0.607, P〈0.05 between populations of the two species, indicating that they were highly genetically diverged from each other. The present data assures the previous results on the validity of the present taxonomic situation of the two species and emphasis on the effect of geographic factors （environments type and bioclimatic stages） on the genetic structure of both species.
