SummaryIn order to investigate the mechanism of thrombin inactivation in the presence of both antithrombin III (AT III) and α 2-macroglobulin (α 2 M), thrombin and the inhibitors have been purified from human material and thrombin inactivation studied using purified reagents either alone or added to defibrinated plasma. Comparison of clotting and amidolytic activities of residual thrombin allowed to measure the amount of thrombin bound to α 2 M. In a purified reagent system as well as in plasma, part of exogenous thrombin is bound to α 2 M. The amount of bound thrombin is related to α 2 M concentration. Conversely, previous plasma α 2 M depletion by immunoabsorption increases the consumption of heparin-cofactor activity by exogenous thrombin. Thus AT III and α 2 M compete for thrombin inactivation. This finding could be of practical interest in clinical situations associating high plasma α 2 M levels and a decrease of AT III concentration.

SummaryThe International Reference Preparation of human brain thromboplastin coded 67/40 has been thought to show evidence of instability. The evidence is discussed and is not thought to be strong; but it is suggested that it would be wise to replace 67/40 with a new preparation of human brain, both for this reason and because 67/40 is in a form (like Thrombotest) in which few workers seem to use human brain. A �plain� preparation would be more appropriate; and a freeze-dried sample of BCT is recommended as the successor preparation. The opportunity should be taken also to replace the corresponding ox and rabbit preparations. In the collaborative study which would be required it would then be desirable to test in parallel the three old and the three new preparations. The relative sensitivities of the old preparations could be compared with those found in earlier studies to obtain further evidence on the stability of 67/40; if stability were confirmed, the new preparations should be calibrated against it, but if not, the new human material should receive a calibration constant of 1.0 and the new ox and rabbit materials calibrated against that.The types of evidence available for monitoring the long-term stability of a thromboplastin are discussed.

This chapter examines John Locke's notion of concernment, which for him is more fundamental than the notion of responsibility when it comes to the question of personal identity. It begins with the argument that the being or extent of a subject of experience's personhood or personal identity is not simply identical with the being or extent of its field of responsibility, because the notion of a person is not an exclusively moral or forensic term, as it might be if it concerned only a set of actions. Instead, one's personhood or personal identity also comprises one's substantial constitution, that is, a whole human material body plus an immaterial soul. The chapter considers Locke's view that Concernment entails a capacity for pleasure and pain and shows that that the field of responsibility lies completely inside the field of consciousness, which in turn lies wholly inside the field of concernment.

The effectiveness of the audit is conditioned by the systematic nature of the analyses and their periodicity. In this respect, the work of internal auditors must be coherent, continuous, and professional. These conditions can be met only if the activity is organized as a permanent system, which has its objectives and has resources (human, material, and financial), as well as adequate tools (audit method) corresponding to the activities carried out within the hydro-construction companies. The methodology for assessing the occupational safety status specific to companies in the field of hydrotechnical constructions was tested at the economic operators within SC HIDROCONSTRUCȚIA SA Bucharest. Thus, from the observation made based on the two calculation formulas’ application, it can be appreciated that the weighted amount more clearly and objectively reflects the existence of problems in achieving safety and health at work, thus constituting the result of a cautious approach, as opposed to the arithmetic mean formula, which leads to a result that tends to overestimate the value of the assessment. Additionally, the security risk determination in the field of occupational security at the economic operators was performed, according to the procedure of applying the method, based on the Gumbel probability function associated with insecurity, and the accuracy of various estimates on risk predictors was ensured by using the Kolmogorov–Smirnov statistical verification test in order to determine the confidence interval of the forecast results.

The integrity of myelin sheaths is maintained by oligodendrocytes and Schwann cells respectively in the central nervous system (CNS) and in the peripheral nervous system. The process of demyelination consisting of the withdrawal of myelin sheaths from their axons is a characteristic feature of multiple sclerosis, the most common human demyelinating disease. Many experimental models have been designed to study the biology of demyelination and remyelination (repair of the lost myelin) in the CNS, due to the difficulties in studying human material. In the ethidium bromide (an intercalating gliotoxic drug) model of demyelination, CNS remyelination may be carried out by surviving oligodendrocytes and/or by cells differentiated from the primitive cell lines or either by Schwann cells that invade the CNS. However, some factors such as the age of the experimental animals, intensity and time of exposure to the intercalating chemical and the topography of the lesions have marked influence on the repair of the tissue.

Wood has been one of the most popular building materials of the world and wooden buildings served as the predecessors and prototypes of architecture in history. This paper focuses on a single material, wood, as a tool to discuss the potential continuity of meaning in the material language of architecture and addresses the topic of the material imagination in architecture.

The most enduring aspect of the economic studies of Marx is the exposition in Capital of the inner anatomy of capitalism as the limit form of what a human society should not be—that is a commodified society which abdicates the responsibility for the reproduction of human material existence to something that transcends human force. Deriving from this perspective on Capital is the position that socialism, at least in its most fundamental incarnation, should not be considered as being institutionally prefigured by capitalism, but as the antithesis of capitalism in that regard. Given such an understanding of socialism, I derive three core principles of what I call an ontology of socialism from Marx's work in Capital. I then briefly outline what adherence to the principles implies for the issues of calculation, motivation and discovery in the construction of a genuine socialism.

PEDIATRIC literature and clinical experience contain abundant indications of physiologic immaturity in newborn infants, especially in those born prior to term. Functional immaturity of brain, liver, kidney, immune response and blood coagulation are among the well-recognized peculiarities of the newborn period. Exaggerations of these usually mild, transitory phenomena may contribute to grave disorders and possibly prove to be lethal. In addition to apparent derangements of particular systems or organs, there are occasional infants, notably the delicate offspring of diabetic mothers, whose general response and appearance suggest immaturity disproportionate to size and gestational age. In this group, general metabolic disturbances are suspected which await biochemical localization and characterization. Conventional post-mortem examinations may be discouragingly unrevealing in these babies. For example, one of the most commonly encountered problems is that of infants dying following unexplained respiratory distress. Pathologically, only so-called "hyaline membranes" with atelectasis have been found. This pattern can be noted in at least half of all infants of diabetic mothers and prematures and occasionally in a full-term baby, and constitutes one of the most baffling problems in clinical pediatrics today. In contrast, the increasing availability of biochemical methods of study are providing a rapidly growing fund of information concerning the normal fetus and newborn. From studies on the chemical embryology of other species and from limited similar work with human material, characteristic patterns of chemical differentiation are emerging. Extension of such observations may be expected to permit the establishment of new metabolic parameters by which to assess the developing fetus and infant.

PurposeThis study highlights the findings of an empirical study to investigate waste factors (WFs) affecting the performance and delivery of construction projects in developing countries. The objectives of this study are to identify non-physical WFs in developing nations and rank the identified factors based on their degree of influence on the key performance indicators (KPIs) of cost, quality and time.Design/methodology/approachIn total, 34 WFs were identified through a detailed literature review and consolidated using semi-structured interviews with construction practitioners. The statistical analysis involved a normality test using the Shapiro–Wilk test to determine if sample data have been drawn from a normally distributed population, ranking the WFs using the Frequency Index (FI), Severity Index (SI) and Importance Index (IMPI), ranking the WFs based on their effect on the project KPIs of cost, quality and time, and identify clustering structures for the identified WFs to using factor analysis (FA).FindingsThe results revealed ineffective planning and scheduling, rework/repair of defective work and resource quality problems (human, material and equipment) as the three most important WFs affecting construction projects. The factor analyses showed that WFs can be grouped into five interrelated components, suggesting the need for integrated and holistic strategies to overcome the identified WF.Practical implicationsUnderstanding the effects of WFs on construction projects is a first step towards designing holistic solutions to ensuring projects deliver value to the clients and other stakeholders. The findings of this study provide direction to construction practitioners on where to focus appropriate strategies to manage the identified WFs effectively and, therefore, improve the productivity of construction projects.Originality/valueThis study provides the first holistic analysis of WFs affecting the productivity of construction projects in developing countries.
