The two-stage clonal expansion model in occupational cancer epidemiology: Results from three cohort studies

Copyright © 2010 by the BMJ Publishing Group Ltd. All rights reserved.Objectives: The objective of this work was to apply the two-stage clonal expansion model, with the intention to expand the literature on epidemiological applications of the model and demonstrate the feasibility of incorporating biologically based modelling methods into the widely used retrospective cohort study. Methods: The authors fitted the two-stage clonal expansion model model to three occupational cohort studies: (1) a cohort of textile workers exposed to asbestos and followed for lung cancer mortality; (2) a cohort of diatomaceous earth workers exposed to silica and also followed for lung cancer mortality; and (3) a cohort of automotive manufacturing workers exposed to straight metalworking fluid (MWF) and followed for larynx cancer incidence. The model allowed the authors to estimate exposure effects in three stages: cancer initiation (early effects), promotion or malignant transformation (late effects). Results: In the first cohort, the authors found strong evidence for an early effect of asbestos on lung cancer risk. Findings from analyses of the second cohort suggested early and less evidently late effects of silica on lung cancer risk. In the MWF (third) cohort, there was only weak evidence of straight MWF exposure effects on both early and late stages. The authors also observed a late birth cohort effect on larynx cancer risk. Conclusions: The findings for asbestos and silica were essentially confirmatory, supporting evidence for their early effects on lung cancer from a large body of literature. The effect of straight MWF on larynx cancer was less clear.This work was supported by a grant from the US National Institute for Occupational Safety and Health, Centers for Disease Control and Prevention,R01-OH03575, and a grant from the Centers for Disease Control and Prevention/ Association of Teachers of Preventive Medicine number TS 0699

Project and Adjustment of Industrial Enterprise Protections

Import 29/09/2010Moderní elektrické ochrany jsou složitá a drahá zařízení, sloužící k zajištění spolehlivého chodu elektrizační soustavy a elektrických zařízení. Publikace je rozdělena na dvě části – teoretickou a praktickou. Úvod teoretické části je věnován rozboru elektrických ochran, definováním základních členů elektrických ochran a jejich rozdělením. Další část je pak věnovaná základním pojmům a vztahům z oblasti teorie zkratových proudů. Praktická část Diplomové práce pak obsahuje popis a zhodnocení stávajícího stavu chránění ve skutečném průmyslovém podniku, návrh nových ochran pro rozvodnu, výpočet zkratových poměrů na rozvodnách R4, R13, R14 a návrh na nastavení ochran vývodů vysokého napětí a transformátorů na rozvodně R14. Kontrola správnosti řešení je rovněž součástí Diplomové práce.Modern industrial enterprise protections are complicated and expensive equipment to secure reliability operation of power systems and electrical equipments. The publication is divided into two parts - theoretical and practical. Introduction of the theoretical part is devoted to analysis of electrical protections, define basic parts of electrical protection and electrical equipment. Another section is devoted to basic conception and formulas from the theory of short-circuit currents. Practical part includes a description and evaluation of the technical state of protection in real industrial company, projection of the new electric protections, the calculation of short-circuit conditions at the electrical substations R4, R13, R14, calculations for the settings of new electrical protections for calbes and transformers at R14. Dissertation also includes a control calculation.Prezenční451 - Katedra elektroenergetikyvýborn
