The distribution law of thawing temperature field, calculation formulas of thawing radius b, heat flux density q and average thawing temperature T were obtained. It theoretically explains that the main influential factors of thawing radius b, heat flux density q and thawing average temperature T are K,f, Lx and co(l), but Lc affects little. Finally, based on the forcible thawing project of Hulusu air shaft lining, the field data indicate that the analytical formulas of this article are comparatively accurate.展开更多

Symptoms concerning for a cancer diagnosis are not easily evaluated and treated by healthcare systems available to this population. We conducted a rapid needs assessment of cancer screening and pain and palliative care with the goal of identifying the prevalence of cancer risk factors among the Rohingya who attended local health facilities. Methods: A cross-sectional study was conducted in the Kutupalong camp of Ukhiya, Cox’s Bazar among the Rohingya community. Data were?collected through purposive sampling. Face-to-face interviews were done using a structured questionnaire. Statistics were analyzed by using IBM SPSS 23.?Results: Out of 85 participants, 75 were female and 10 were male. 70 (82.4%) were uneducated (defined as lacking any formal institutional education), 10 (11.8%) people completed the primary level education and only 5 (5.9%) people received secondary level education. There were many participants with pulmonary disease with 35 (41.2%) people endorsing a history of asthma, bronchitis, and/or tuberculosis. There was a lack of female menstrual sanitation and hygiene with only 25 (29.4%) patients using sanitary napkins, that were donated by Non Government Organizations. Only 5.9% of the women had received any form of cervical cancer screening.?Conclusion: This study identifies risk factors associated with cancers and life-limiting diseases among the FDMN Rohingya refugees in Bangladesh. It is necessary to develop targeted education, cancer screening and cancer awareness programs for this population.展开更多

According to the dimensionless load separation principle, the normalization method has been improved by intro- ducing a forcible blunting correction. With the improved normalization method, the J-resistance curves of five different metallic materials of CT and SEB specimens are estimated. The forcible blunting correction of initial crack size plays an important role in the J-resistance curve estima- tion, which is closely related to the strain hardening level of material. The higher level of strain hardening leads to a greater difference in JQ determined by different slopes of the blunting line. If the blunting line coefficient recommended by ASTM E1820-11 is used in the improved nor- realization method, it will lead to greater fracture resistance than that processed by the blunting line coefficient recommended by ISO 12135-2002. Therefore, the influence of the blunting line on the determination of JQ must be taken into full account in the fracture toughness assessment of metallic materials.展开更多

In this paper, we obtain a new sufficient degree condition for π to be forcibly k-edgeconnected. We also show that this new sufficient degree condition implies a strongest monotone degree condition for π to be forcibly 2-edge-connected and a conjecture about a strongest monotone degree condition for π to be forcibly 3-edge-connected due to Bauer et al.(Networks, 54(2)(2009) 95-98), and also implies a strongest monotone degree condition for π to be forcibly 4-edge-connected.展开更多
