Materials decay and environmental attack in the Pio Palace at Carpi: A holistic approach for historical architectural surfaces conservation

Since the XIV century the Pio Palace in Carpi (MO, Italy) has been subjected to many additions and rearrangements and, in the last decades, to wide restoration works. Nevertheless the XVII century main portal has not been restored yet, due to its complex and peculiar surface alteration forms in comparison with the other parts of the building, and still suffers a deep decay and degradation by complex chemical-physical processes.     

Mixed Portmanteau Tests for Time‐Series Models

Abstract. This paper obtains the joint limiting distribution of residuals and squared residuals of a general time‐series model. Based on this, we propose a mixed portmanteau statistic for testing the adequacy of fitted time‐series models. In some cases, it is shown that this statistic can be simply approximated by the sum of well‐known portmanteau statistics. The finite‐sample performance of the new test is compared with those of well‐known tests through simulations.     

Wheel-flat diagnostic tool via wavelet transform

The detection and acknowledgement of signatures, for condition monitoring and fault diagnostics by wavelet transform, deserves increased attention, due to its property of variable time–frequency resolution, which overcomes limitations of classical time–frequency approaches.In the paper, a diagnostic tool is presented, based on the wavelet transform, able to detect and to quantify the wheel-flat defect of a test train at different speeds and to measure the train speed with proper accuracy. The designed diagnostic tool minimises the hardware requirements, since only one accelerometer is needed, and provides results in real time.The results, achieved by an exhaustive experimental campaign, permit to validate the effectiveness of the diagnostic tool and to demonstrate the advantages of wavelet-based detection of signatures.

Review of From conflict to resolution: Strategies for diagnosis and treatment of distressed individuals, couples, and families.

Reviews the book, From conflict to resolution: Strategies for diagnosis and treatment of distressed individuals, couples, and families by Susan Heitler (see record 1990-97228-000). The title of Heitler's book, although cumbersome, reflects well the heroic scope of her effort. She will not partake of the contemporary obsession for minimodels, so reassuringly precise, so frustratingly narrow. No, she will settle for nothing less than a comprehensive model of clinical work, a single framework capable of embodying all types of therapy with all types of clients. From one perspective, the grandiosity of this ambition seems laughably anachronistic, more befitting the early rather than the late twentieth century. From a slightly different viewpoint, however, the dramatic scope emerges as startlingly modern. After all, for some time now the myriad voices of eclecticism have cried for a serviceable infrastructure, a defensible and robust strategy for the integration of endlessly proliferating techniques. Heitler has given us such a framework. It arrives in the deceptively simple, pleasingly familiar concept of conflict. She defines conflict as "a situation in which seemingly incompatible elements exert force in opposing or divergent directions," and flatly states her assumption that "the health of any given system, be it an individual, couple, or group, can be seen as a function of its ability to negotiate conflicts." The focus of her work is not so much upon the content of various conflicts, but rather the underlying process through which they are handled. This is a book designed for immediate practical utility: It is replete with tables listing interventions for various problems, and it is fleshed out at every possible point with voluminous case material. Still, the value of this work resides not in its encyclopedic compendium of techniques, but rather in its integrative vision. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Assessing match and mismatch between practitioner-generated and standardized interview-generated diagnoses for clinic-referred children and adolescents.

Although the Diagnostic and Statistical Manual of Mental Disorders (DSM) is widely used in both clinical and research settings, little is known about agreement between clinician and standardized research diagnoses. Diagnoses generated by the Diagnostic Interview Schedule for Children (DISC-P--2.3) were compared with clinician-generated diagnoses for 245 referred youths. Agreement was poor for all individual disorders and broader diagnostic clusters. Agreement was higher for externalizing categories than for internalizing, but no association was found between agreement and child, family, or clinician characteristics. Clinicians were more likely than the DISC to assign 1 diagnosis and less likely to assign 0 diagnoses, suggesting that clinic policies may play a role. Implications for the use of the DSM across different settings are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

应力敏感裂缝型油藏物质平衡方程计算新方法

对复杂的应力敏感裂缝型油藏来说,裂缝系统的储量大小对整个油田的开发起着至关重要的作用。以物质平衡方程为基础,研究了应力敏感裂缝型油藏储量的计算方法。采用实际覆压实验数据建立了数值模拟单井概念模型,使用模型模拟计算的压力、产量数据,该方法可分别计算出裂缝和岩块系统原油储量,与实际储量的对比验证了方法的正确性。结果表明,不考虑裂缝压缩系数变化时,采用物质平衡方程计算的裂缝储量明显小于实际值;考虑裂缝系统压缩系数变化后可以准确计算裂缝系统储量,计算误差在5%以内;该研究结果对应力敏感裂缝型油藏高效开发具有指导意义。     

血清 AFU、LAP 及 GGT 联合检测在早期原发性肝癌患者诊断中的应用价值
