Energetic characteristics of cycles： specific mass and volume cooling capacity q0 and qv, work of compression 1, refrigerating coefficient of performance e and power N for drive of compressor were compared. These characteristics were calculated for eight refrigerants at temperature of their condensation 30 ℃ and temperatures of boiling -15℃ and -30 ℃. The calculations show that the use of isothermal compression of refrigerant vapor ensures economy of energy during refrigerating machine operation.展开更多

However, through out history, religions have been threatened by politico-military and religious aggressions from other peoples, by heterodoxies, alternative origin-stories, practices and beliefs. These threats became unprecedented with the advent of Modernity. Faced with these destabilizing agents, they resorted to citing textual authorities, strengthening their institutions, giving leaders more powers, precisely defining belief commitments, punishing heretics and using violence against heterodoxies. Consequently, in their obsessive quest for preserving the sanctity of their faiths against modern threats, religions or section of a religion adopted both revival and resistant measures. Fundamentalism thus developed within these contexts. This paper intends to reveal that religious militancy and militarism are ramifications of Fundamentalism. It argues that Modernity＇s destabilizing agents to religions and religions＇ passionate desire for self-protective steps, militant or militaristic, yield to the phenomenon of Fundamentalism. Secondary sources were used to assemble the data while analytical and comparative approaches with empirical emphases on Christianity and Islam were used to weave the findings with the finality that militant or militaristic, Fundamentalism is religions＇ obsessive response to Modernity,展开更多

RevMan v5.0.20 was used for statisticalanalyses.RESULTS: Fourteen RCTs involving 637 patients were collected.Thirteen RCTs compared the effects of HSM and Western Medicine. After 3-month treatment and after 6-month follow-up, there was no significant difference in effective rate [relative risk(RR)=1.01, 95% CI(0.92, 1.12), and 1.12,(0.93, 1.36),respectively], in the asthma control test score of asthma symptoms [weighted mean difference(WMD)=﹣1.54, 95% CI(﹣3.54, 0.47), and 1.41,(﹣0.48, 3.29), respectively] and in the forced expiratory volumein 1 second(FEV1)and peak expiratory flow(PEF). One RCT compared the effect of HSM with warm-suspended moxibustion. After 6-month follow-up, there was a significant difference in FEV1 and PEF [WMD=0.51, 95% CI(0.10, 0.92), and 1.78,(1.06, 2.50), respectively]. After 3-month treatment,there was no significant difference between the two groups. One RCT compared the effect of HSM with acupoint application. After 3-month treatment, there was no significant difference in the effectiverate[RR=0.68,95%CI(0.42,1.12)].CONCLUSION: HSM did not show superiority to conventional Western Medicine and acupoint application in terms of curative effects, and may be superior to warm-suspended moxibustion with regard to long-term curative effects. Because of low quality of the included RCTs, this conclusion must be bolstered with higher-quality RCTs.展开更多
