Caution to Apply Magnetic Barkhausen Noise Method to Nondestructive Evaluation of Plastic Deformation in Some Ferromagnetic Materials

Magnetic Barkhausen Noise(MBN) method is known as an effective nondestructive evaluation(NDE) method for evaluation of residual stress in ferromagnetic materials. Some studies on the feasibility of the MBN method for NDE of residual strains were also conducted and found applicable. However, these studies are mainly focused on the state of residual strains which were introduced through a one-cycle-loading process. In practice, however, structures may suffer from an unpredictable and complicated loading history, i.e., the final state of plastic strain may be induced by several times of large loads. Whether the loading history has influences on MBN signals or not is of great importance for the practical application of the MBN method. In this paper, several ferromagnetic specimens with the same final state of residual strain but of different loading history were fabricated and inspected by using a MBN testing system. The experimental results reveal that the loading history has a significant influence on the detected MBN signals especially for a residual strain in range less than 1%, which doubts the feasibility to apply the MBN method simply in the practical environment. In addition, micro-observations on the magnetic domain structures of the plastic damaged specimens were also carried out to clarify the influence mechanism of loading history on the MBN signals.

Background Following on from an earlier study published in 2008 about left pulmonary artery(LPA)flow measured on serial echocardiography being strongly prognostic in left-sided congenital diaphragmatic hernia(CDH)and the ratio of LPA to right pulmonary artery(RPA)diameters being a simple and reliable indicator for commencing nitric oxide(NO)therapy,the ratio of LPA:RPA diameters(PA ratio orPAR)was hypothesized to possibly reflect cardiopulmonary stresses accompanying CDH *** Subjects with isolated left-sided CDH treated between 2007 and 2020 at a single pediatric surgical center were recruited and classified according to *** obtained retrospectively for subject demographics,clinical course,LPA/RPA diameters,and PAR were compared between survivors and *** value of PAR for optimizing the prognostic value of PA diameter data in CDH were analyzed with receiver operating characteristic(ROC)curve *** Of 65 subjects,there were 54 survivors(82.3%)and 11 non-survivors(17.7%);7 of 11 non-survivors died before surgical repair could be *** PAR for survivors(0.851±0.152)was significantly higher than for non-survivors(0.672±0.108)(p=0.0003).Mean PAR for non-survivors was not affected by surgical *** of survivors were:LPA≥2 mm(n=52 of 54;mean PAR=0.866±0.146)and RPA≥3mm(n=46 of 54;mean PAR=0.857±0.152).Non-survivors with similar LPA and RPA diameters to survivors had significantly lower mean *** curve cut-off for PAR was *** with high PAR(≥0.762)required high-frequency oscillatory ventilation/NO less than subjects with low PAR(<0.762)(p=0.0244 and p=0.0485,respectively)and subjects with high PAR stabilized significantly earlier than subjects with low PAR(1.71±0.68 days vs 3.20±0.87 days)(p<0.0001).Conclusions PAR would appear to be strongly correlated with clinical outcome in CDH and be useful for planning management of cardiopulmonary instability in CDH.

近年来,vernacular作为英语民俗学理论中的重要概念,已涌入日本的民俗学领域,并逐步推动民俗学理论更新。在这个过程中,我提出从“反霸权”和“反启蒙”的角度重新定义“民俗学”和“民俗”。这并不是对vernacular概念直接、机械地引用,而是根植于自身现实的理论尝试。结合当代学术史和个人实践经验,vernacular概念的嵌入,将有助于推动日本民俗学的学科建设与更新,及其相关内在理论的构建。

第二次世界大战后,认为“民俗”是“不易变化的事象”“风俗”是“容易变化的事象”的观点在日本传播开来。在这种二分法的理解中,前者被解释为“民俗学”,后者被解释为“风俗学”和“考现学”。本文将民俗等同于vernacular,并将其定义为“在共享某种社会语境的群体中,从某个个人的生世界里产生并活化的经验、知识、表现。特别是我们能从中发现,或预期能从中发现与霸权主义、普世主义、主流和中心的立场相悖的意识、感情、感觉。”在此,“不易变化的事象”及“容易变化的事象”都可以被视作vernacular。

民俗学与文化人类学的缘起及背景各不相同。民俗学是一门相对化、批判霸权主义的学科。本文以海外民俗学的学术史和理论为基础,概述日本民俗学的存在方式,展示体系化的“民俗学”概要,论述了现代民俗学所具备的特性与可能性。除柳田构建的“社会变动—生活世界(生世界)”民俗学外,日本民俗学还有着与其他各领域融合的多种姿态。民俗学在保持对自身严厉批判的同时,将在野性内化为强项,可以构筑独自的学问世界。在当代全球语境下,“世界民俗学”作为当前的课题,正在朝着实现的方向迈进。
