Periodic Changes

Since World War II, periodic changes in the fabrication, design, and material specifications for ship steels have been made to preclude brittle fractures. These various changes are described briefly, along with a history of fracture control for ships to serve as background information for a discussion of the present-day structural integrity program for ships in the marine industry. As additional information related to the structural integrity of ship structures, a review of two recent ship failures (e.g., the Ingram Barge in 1972 and the Chester A. Poling in 1977) is presented to demonstrate some of the factors involved in brittle fractures of ships. In both of these failures there were other factors contributing to the final brittle fractures that were more important than the notch toughness levels. These factors are reviewed as the basis for an observation regarding the overall structural integrity of merchant ships.

AbstractAfter the death of his father Isaac Feitama in 1709, the young Sybrand continued collecting, making several purchases that same year. Not all of them were happy ones, however. The Presentation in the Temple by Jan van Neck (Fig. 1, Note 2), bought from Simon Schijnvoet, proved to be a worked-up offset of the original drawing, which he eventually acquired from his friend Egidius Beukelaar in 1736 (Fig. 2, Note 3), so he sold it to L.F. Duboug in 1754 (Note 5). He seems not to have known that the original drawing was probably a preliminary study for the altarpiece mentioned by Houbraken as Van Neck's best work (Note 4). As in this case, so most of the background information on the Feitama drawings has been lost since the sale of 1758, the catalogue giving only a description of the subject, the measurements and the technique (Note 6). It is precisely the additional information that makes the 'Notitie' so fascinating, although the least interesting part of it now are the prices Sybrand 11 noted so carefully as his own main concern. It is worth noting, however, that exceptionally high prices are mentioned for sheets by Nicolaas Berchem, Gerard Dou, Frans van Mieris, Adriaen van Ostade and Adriaen van de Velde, Rembrandt coming nowhere by comparison. Some of the valuable information provided by the `Notitie' was dealt with in the previous article (Note 7). Some of this is very clear, e.g. in the case of a Ruisdael drawing virtually certainly to be identified with a view of the country-house Kostverloren (Fig. 3, Note 8). The authenticity of this work, which was bought by Cornelis Ploos van Amstel in 1758, has been doubted (Note 10), but the problem would seem to be solved by Feitama's note that it is one of those which Dirck Dalens acquired from Ruisdael's estate after 1682 and subsequently worked up (Note 11). Another of these is a view of Alkmaar now in Budapest (Fig. 4, Note 13). An example of additional information that might easily be overlooked is the note relating to a drawing by Frederik de Moucheron bought in 1745. This must have come from the album of

Abstract Background Frequent and repeated visits from patients with mental illness or free medical care recipients may elicit physicians’ negative emotions and influence their clinical decision making. This study investigated the impact of the psychiatric or social background of such patients on physicians’ decision making about whether to offer recommendations for further examinations and whether they expressed an appropriate disposition toward the patient. Methods A randomized, controlled multi-centre study of residents in transitional, internal medicine, or emergency medicine was conducted in five hospitals. Upon randomization, participants were stratified by gender and postgraduate year, and they were allocated to scenario set 1 or 2. They answered questions pertaining to decision-making based on eight clinical vignettes. Half of the eight vignettes presented to scenario set 1 included additional patient information, such as that the patient had a past medical history of schizophrenia or that the patient was a recipient of free care who made frequent visits to the doctor (biased vignettes). The other half included no additional information (neutral vignettes). For scenario set 2, the four biased vignettes presented to scenario set 1 were neutralized, and the four neutral vignettes were rendered biased by providing additional information. After reading, participants answered decision-making questions regarding diagnostic examination, interventions, or patient disposition. The primary analysis was a repeated-measures ANOVA on the mean management accuracy score, with patient background information as a within-subject factor (no bias, free care recipients, or history of schizophrenia). Results A total of 207 questionnaires were collected. Repeated-measures ANOVA showed that additional background information had influence on mean accuracy score (F(7, 206) = 13.84, p <  0.001 partial η2 = 0.063). Post hoc pairwise multiple comparison test, Sidak test, showed a significant difference between schizophrenia and no bias condition (p <  0.05). The ratings for patient likability were lower in the biased vignettes compared to the neutral vignettes, which was associated with the lower utilization of medical resources by the physicians. Conclusions Additional background information on past medical history of schizophrenia increased physicians’ mistakes in decision making. Patients’ psychiatric backgrounds should not bias physicians’ decision-making. Based on these findings, physicians are recommended to avoid being influenced by medically unrelated information.

Stress Analyses

Alternative rules for performing flexibility analysis were added, as Appendix P, in ASME B31.3, the Process Piping Code, 2004 edition. These rules are considered to be more comprehensive than before; they were designed around computer flexibility analysis. To determine stress range, the difference in stress states, considering all loads, is computed. This paper describes the new rules, their intent, and provides several example piping stress analyses, comparing the results of an analysis using the Appendix P rules with that using the rules in the base Code.

AbstractThis paper presents the most important technical tools that are needed for designing homogeneous photoreactors using computer simulation of a rigorous mathematical description of the reactor performance. Employing intrinsic reaction kinetic models and parameters derived from properly analyzed laboratory information, it is shown that is possible to scale up reactors with no additional information and without resorting to empirically adjusted correcting factors. The method is illustrated with two processes of degradation of organic pollutants as typical applications of the newly developed Advanced Oxidation Technologies. Two reactors, having pilot plant sizes, are modeled to show the proposed approach. Predictions from the models are compared with experimental data obtaining reasonable good results. They provide confidence on mathematical modeling as a design methodology for homogeneous photochemical reactors.

Abstract An impairment evaluation aims to produce a report that is clear and consistent with the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fourth Edition, which outlines the three-step process of medical evaluation, analysis of the findings, and comparison of the results with the impairment criteria. This article reviews common errors that can occur in each of these steps. Medical evaluation is the basis for the evaluation of impairment and relies on the patient's medical history; the latter must include adequate background information, specify data sources, document pre-existing status and specifics of the injury, and document history from onset to current status. The medical evaluation should support a report that explains the effects of the medical condition on life activities; whether the medical condition is stable; whether the individual is likely to suffer incapacitation, injury, harm, or further impairment; and whether restrictions or accommodations are warranted. Common errors in this step include determinations of permanency and stability, and raters should be aware that the AMA Guides is used to assess impairment, not disability. Forms from the AMA Guides are appropriate and help mitigate errors. An audit form is included and can help physicians produce consistent, efficient reports.
