Comparison of non-HDL cholesterol and waist circumference vs. triglyceride levels and waist circumference in predicting coronary heart disease risk

BACKGROUND: Dyslipidemia is recognized as a major cause of coronary heart disease (CHD). Emerged evidence suggests that the combination of triglycerides (TG) and waist circumference can be used to predict the risk of CHD. However, considering the known limitations of TG, non-high-density lipoprotein (non-HDL = Total cholesterol - HDL cholesterol) cholesterol and waist circumference model may be a better predictor of CHD. PURPOSE: The Framingham Offspring Study data were used to determine if combined non-HDL cholesterol and waist circumference is equivalent to or better than TG and waist circumference (hypertriglyceridemic waist phenotype) in predicting risk of CHD. METHODS: A total of3,196 individuals from Framingham Offspring Study, aged ~ 40 years old, who fasted overnight for ~ 9 hours, and had no missing information on nonHDL cholesterol, TG levels, and waist circumference measurements, were included in the analysis. Receiver Operator Characteristic Curve (ROC) Area Under the Curve (AUC) was used to compare the predictive ability of non-HDL cholesterol and waist circumference and TG and waist circumference. Cox proportional-hazards models were used to examine the association between the joint distributions of non-HDL cholesterol, waist circumference, and non-fatal CHD; TG, waist circumference, and non-fatal CHD; and the joint distribution of non-HDL cholesterol and TG by waist circumference strata, after adjusting for age, gender, smoking, alcohol consumption, diabetes, and hypertension status. RESULTS: The ROC AUC associated with non-HDL cholesterol and waist circumference and TG and waist circumference are 0.6428 (CI: 0.6183, 0.6673) and 0.6299 (CI: 0.6049, 0.6548) respectively. The difference in the ROC AVC is 1.29%. The p-value testing if the difference in the ROC AVCs between the two models is zero is 0.10. There was a strong positive association between non-HDL cholesterol and the risk for non-fatal CHD within each TO levels than that for TO levels within each level of nonHDL cholesterol, especially in individuals with high waist circumference status. CONCLUSION: The results suggest that the model including non-HDL cholesterol and waist circumference may be superior at predicting CHD compared to the model including TO and waist circumference.

La face et la figuration: une analyse interactionnelle tirée de l’instruction de base des Forces canadiennes

Le sujet de ce mémoire émane d’une volonté d’intégrer la recherche à ma réalité organisationnelle, celle des Forces canadiennes (FC). De cette aspiration est née l’idée d’étudier comment se dévoilent la face et la figuration lors de l’instruction de base. Partant d’une approche interactionniste, l’attention a été portée sur la face et la figuration d’un stagiaire au cours de trois interactions avec ses supérieurs. C’est plus précisément, la filature et l’analyse de conversation qui ont été mobilisées pour examiner cette problématique. La pertinence de la démarche est qu'elle met de l'avant une perspective de recherche peu présente dans la littérature, mais surtout, qu’elle s’insère dans un contexte organisationnel méconnu. L'entreprise vise d’une part, à nourrir la théorie en raffinant des concepts existants : la face et la figuration. D’autre part, elle cherche à éclairer la pratique en mettant en évidence des actes communicationnels difficilement observables dans le cadre habituel des activités militaires.

Recycling of NR Based Cured Latex Material Reclaimed with 2,2'-Dibenzamidodiphenyldisulphide in a TruckTire Tread Compound

It is observed that reclamation of natural rubber latex based rubber using 2,2'-dibenzamidodiphenvldisulphide as reclaiming agent is an optional methodology for recycling of waste latex rubber (WLR). For progressive replacement of virgin natural rubber by the reclaim, two alternatives curing system were investigated: adjustment or reduction of the curing system with increasing reclaim content, to compensate for the extra amount of curatives brought along by the reclaim. For fixed curing system, as if the reclaim were equivalent to virgin NR. The cure behavior, final crosslink density and distribution, mechanical properties, and dynamic viscoelastic properties of the blends with reclaimed WLR are measured and compared with the virgin compound. The morphology of the blends, sulfur migration, and final distribution are analyzed.The mechanical and dynamic viscoelastic properties deteriorate for both curing systems, but to a lesser extent for fixed curing system compared to adjusted curing system. With the fixed cure system, many properties like tensile strength and compression set do still deteriorate, but tan 6 and Mrrr„/Murxr, representative for the rolling resistance of tires are improved. On the other hand, with the adjusted cure system both mechanical and dynamic properties still deteriorate.

Studies on Rubber-to-Nylon Tire Cord Bonding

ABSTRACT: Nylon tire cord (1680/2) was dipped in different adhesives based on resorcinol formaldehyde resin and latex (RFL) and was bonded to natural rubber-based compounds. The resin-rubber ratio in the RFL adhesive was optimized. The variation of pull-through load was studied by varying the drying and curing temperature of the dipped nylon tire cord. RFL adhesive based on vinylpyridine latex was found to have better rubber-to-nylon tire cord bonding, compared with the one based on natural rubber latex. Addition of a formaldehyde donor into the RFL adhesive/rubber compound improves adhesion.

Série tirée des essais de mise en commun de termes en vrac se référant aux acteurs, aux notions empruntées au social, au politique, à l'education, à la terminologie courante de la muséologie adaptée aux présupposés de la muséologie sociale

POPULATION = Terme générique pour désigner l’adhésion d’une population, ou d’un groupe significatif de citoyens d’un territoire d’appartenance, au projet de muséologie sociale. Celle-ci se mesure par le degré de participation, d’implication et de vision partagée, d’interaction au sein de la collectivité territoriale, son fief. PARTICIPANTS = Sont les acteurs actifs au sein de la population adhérante, partie prenante au projet de muséologie social. La participation se mesure selon le degré d’implication dans le projet et de compréhension de celui-ci (Intérêt, gestion partagée, militance, volonté de capacitation...) COOPÉRANT = Par solidarité, par engagement, il s’insère dans le système de l’action ccopérative, possédant ses règles propres, offrant sa contribution à l’unité de production conciliant la dimension sociale (de la muséologie), son idée au regroupement de personnes désireuses de contribuer à la production commune de biens de qualité au service de la population dont ils sont issus.

Design, implementation and testing of an intelligent knowledge-based system for the supervisory control of a hot rolling mill

This paper describes the design, implementation and testing of an intelligent knowledge-based supervisory control (IKBSC) system for a hot rolling mill process. A novel architecture is used to integrate an expert system with an existing supervisory control system and a new optimization methodology for scheduling the soaking pits in which the material is heated prior to rolling. The resulting IKBSC system was applied to an aluminium hot rolling mill process to improve the shape quality of low-gauge plate and to optimise the use of the soaking pits to reduce energy consumption. The results from the trials demonstrate the advantages to be gained from the IKBSC system that integrates knowledge contained within data, plant and human resources with existing model-based systems.
