Effects were studied of hemosorption on the system of homeostasis in patients with chronic glomerulonephritis presenting with nephrotic syndrome. An optimum graphic express method of control of the homeostasis system state was found, permitting predicting thrombohemorrhagic complications after single-session hemosorption (significance 99.9%). Strategies were identified for correction of changes in coagulogrammes in such patients along with devising measures to prevent the above complications. 相似文献

The validity of Verbal IQ as a short form of the WAIS was investigated using the criteria proposed by R. J. Resnick and A. O. Entin (see record 1971-09973-001). The WAIS was administered to 100 psychiatric patients of whom 39 were psychotics, 54 non-psychotic, 6 brain-damaged, and 1 unclassified. A Pearson product-moment correlation of .97 ( p 相似文献

W. M. Reynolds (see record 1979-25128-001) criticized the present authors because of their use of improper statistics in supporting the validity of the WAIS Verbal IQ as a short form of the Full Scale IQ. The authors agree with Reynolds that they erred in the choice of one statistical test. However, it is maintained that from a practical standpoint, the use of the Verbal IQ as a short form had considerable value as a screening device and should not be discarded because of this one criticism.

Recent theorizing in moral psychology extends rationalist models by calling attention to social and cultural influences (J. Haidt, 2001). Six studies using adolescents, university students, and adults measured the associations among the self-importance of moral identity, moral cognitions, and behavior. The psychometric properties of the measure were assessed through an examination of the underlying factor structure (Study 1) and convergent, nomological, and discriminant validity analyses (Studies 2 and 3). The predictive validity of the instrument was assessed by examinations of the relationships among the self-importance of moral identity, various psychological outcomes, and behavior (Studies 4, 5, and 6). The results are discussed in terms of models of moral behavior, social identity measurement, and the need to consider moral self-conceptions in explaining moral conduct.

A planar cable-direct-driven robot (CDDR) architecture is introduced with only translational freedoms. The motivation behind this work is to improve the serious cable interference problem with existing CDDRs and to avoid configurations where negative cable tensions are required to exert general forces on the environment and during dynamic motions. These problems generally arise for rotational CDDR motions. Thus, we propose a class of purely translational CDDRs; of course, these are not general but may only perform tasks where no rotational motion or resistance of moments is required at the end-effector. This article includes kinematics and statics modeling, determination of the statics workspace (the space wherein all possible Cartesian forces may be exerted with only positive cable tensions), plus a dynamics model and simulated control for planar translational CDDRs. Examples are presented to demonstrate simulated control including feedback linearization of the 4-cable CDDR (with two degrees of actuation redundancy) performing a Cartesian task. We introduce an on-line dynamic minimum torque estimation algorithm to ensure all cable tensions remain positive for all motion; otherwise slack cables result from the CDDR dynamics and control is lost. 相似文献

Life safety concerns related to fires and explosions are critical design issues for large subsurface facilities. This paper reviews these issues and discusses them in terms of existing life safety codes. The authors apply principles of layout and physical design for life safety to the development of large mined space facilities in the City of Minneapolis. Also discusses is a case study of life safety standards for a large underground building under consideration at the University of Minnesota. 相似文献
