Four-phonon model of soft-matter quasicrystals is proposed, in which there are three solid phonons and one fluid phonon. With this model, the vibration spectrum of soft-matter quasicrystals can be obtained. The generalized Debye frequency, generalized Debye temperature and the thermodynamic functions of soft-matter quasicrystals are observed. The results on the specific heat of soft-matter quasicrystals demonstrate the contributions of both solid phonons and fluid phonon, respectively. 相似文献

The role of feedback in the development of recognition memory was examined by testing pairs of subjects; one subject performed the movement while the other listened to the movement in an adjacent room. Both groups of subjects developed recognition memory during training with KR, and recognition performance was virtually identical for both groups. In addition, previous experience with the sensory consequences of the movement led to improved response production during initial trials. A possible mechanism to account for this finding is proposed. Appreciation is extended to Richard A. Schmidt and Anne Marie Bird for helpful comments in earlier drafts of this paper. 相似文献

The Y-groove cracking test by submerged arc welding was employed to study the susceptibility of a low-carbon high-strength steel to hydrogen-induced cold cracking (HICC). The morphology of hydrogen cracks was observed using an electron probe microscope. The results showed that the heat-affected zone (HAZ) has a higher susceptibility to HICC than the weld metal and that increasing heat input can improve the HICC resistance of the weldment. The intergranular microcracking is the main HICC mode at the lowest heat input condition, accompanied with some transgranular microcracks attached to complex inclusions. In combination with phase transformation behaviour in sub-zones, the effect of the phase transformation sequence is proposed to try to illustrate the fact that the fine-grained HAZ has higher probability of hydrogen cracking than the coarse-grained HAZ owing to the occurrence of hydrogen enrichment in the fine-grained HAZ after the transformation. 相似文献

The specific heat and magnetocaloric effect (MCE) of A-site ordered PrBaMn2O6 manganite have been studied. The anomalies caused by the ferromagnetic (FM) and antiferromagnetic (AFM) phase transitions are revealed in the specific heat curve. Direct and inverse MCE are observed at the Curie and Néel points correspondingly. A value of the inverse MCE in the heating run is smaller than in the cooling regime. We attribute this effect to the competition between FM and AFM interactions. A significant advantage of PrBaMn2O6 as a magnetocaloric material is an MCE spanning a broad range of temperature with a maximum at room temperature. 相似文献

An emerging scientific literature is investigating the construct of “compassionate love,” love that is “centered on the good of the other,” a construct empirically linked to physical and mental health. We evaluated effects of an 8-week, 16-hour programme for physicians, nurses, chaplains, and other health professionals, using nonsectarian, spiritually based, self-management tools. Participants were randomised to intervention (n = 30) or wait-list (n = 31). Pretest, post-test, 8- and 19-week follow-up data were gathered on six measures of prosocial qualities. Favorable treatment effects (p<0.05) were found for compassionate love (d = 0.49), altruistic actions (d = 0.33), perspective-taking (d = 0.42), and forgiveness (d = 0.61). Treatment adherence fully mediated effects on compassionate love. Furthermore, stress reduction mediated treatment effects on compassionate love, perspective-taking, and forgiveness; each also mediated gains in caregiving self-efficacy. This encouraging evidence suggests that nonlaboratory psychospiritual interventions can boost compassionate love to benefit the recipients and the larger society. 相似文献

Social work is a discipline that attracts students from diverse academic backgrounds. Many are first in family to attend university, and come to university through alternative pathways such as vocational education. As a result, there are higher levels of attrition compared to other disciplines, especially in the first year. To address this, and in keeping with a commitment to provide accessible education, one school of social work undertook a project to embed academic literacies into the curriculum. This paper used Gibb’s reflective process to explore how this was experienced by team members. Data were collected via staff focus groups at two different points in time across the project and compared. The reflection unpacked a number of tensions experienced by team members, including concerns about potential loss of resources as a result of academics adopting new roles, and concerns about implementing what was seen as Westernised academic skills which may not fit with students’ ways of thinking and creating knowledge. Overfull curricula and constant change also appeared to be of concern. The reflection highlighted that to achieve effective and sustainable change, action was required at multiple levels. 相似文献

据估计大约50%婴幼儿特应性皮炎和35%成人特应性皮炎患者对常见过敏原过敏。气源性过敏原、食物过敏原和小分子接触性过敏原是特应性皮炎发病的主要环境诱发因素。临床可通过皮肤点刺试验、斑贴试验、特应性斑贴试验等体内试验并结合外周血过敏原特异性IgE检测进行过敏原诊断。当明确与发病相关的过敏原后,回避治疗是首要的原则,对于尘螨等难以完全回避的过敏原,特异性免疫治疗是有可能改善病情并达到长期缓解的治疗手段。 相似文献
