Fire fighting work comprises work tasks requiring an energy yield at maximal or close to maximal levels of the individual. Due to the very nature of fire fighting more complex physiological variables are difficult to measure. We measured metabolic and respiratory responses in 15 male.. professional fire fighters during simulated work tasks on a test ground. Work time was on the average 22 min with

The effects of nicotine administration (2 mg eight-times daily as nicotine chewing gum for two weeks) on plasma lipid and lipoprotein concentrations were studied in young healthy volunteers. Plasma levels of the nicotine metabolite, cotinine, reached levels comparable to those seen in smokers. Plasma concentrations of triglyceride, cholesterol, HDL cholesterol, LDL cholesterol, and apolipoproteins

This article discusses why films have not been used more than they have as historical sources and argues that films ought to be used more by historians. Principally, historians can use film in three basic ways, all of which give access to information about the period when it was produced. First, films can with caution be used for information about the persons, objects and events depicted in docu

beta-Carbolines show structural resemblance to the neurotoxic N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and are metabolized to mitochondrial toxicants. Humans are continuously exposed to low levels of beta-carbolines through cooked food, coffee, alcoholic beverages and tobacco smoke. beta-Carbolines have previously been detected in higher levels in the pigmented substantia nigra than in the cor

A fairly large study of attitudes towards mathematics among Swedish students at secondary level was conducted during 2001–2004. A newly developed instrument was used that was designed to capture gender stereotyped attitudes among students related to various aspects of mathematics in education and future life. The new scale and its development are described with reference to the original Australian

Three microperoxidases-hemin-6(7)-gly-gly-his methyl ester (HGGH), mesohemin-6(7)-gly-gly-his methyl ester (MGGH) and deuterohemin-6(7)-gly-gly-his methyl ester (DGGH)-have been prepared as models for heme-containing peroxidases by condensation Of glycyl-glycyl-L-histidine methyl ester with the propionic side chains of hemin, mesohemin and deuterohemin, respectively. The three microperoxidases dif

The aggravating effect of hyperglycemia on ischemic brain injury can be mimicked in a model of in vitro ischemia (IVI) using murine hippocampal slice cultures. Using this model, we found that the damage in the CA1 region following IVI in the absence or presence of 40 mM glucose (hyperglycemia) is highly temperature dependent. Decreasing the temperature from 35 to 31 degrees C during IVI prevented

Popular Abstract in Swedish Med ett historiskt perspektiv analyserar denna avhandling erfarenheter och identitetsskapande processer hos en grupp kvinnliga arbetare, cashewarbeterskor, i den sydindiska delstaten Kerala-välkänd för dess radikala befolkning och höga sociala indikatorer för invånarna. Cashewarbeterskorna utmanar den stereotypa bilden av kvinnor i ?Tredje Världen?, genom att de sedan 1Since the 1930s female cashew workers have constituted a majority of the registered workers in the South Indian State of Kerala and today number some 200,000. This group challenged the stereotypical view of Third World women because they were organized into unions, worked in the formal sector, and were literate. The background for this thesis has been the ?Kerala Model?, i.e., the political contex

Denna rapport är ett försök att skissera en bild av hur människors uppfattningar och föreställningar om ekonomiska transaktioner via Internet skapas, vidmakthålles och förändras, samt hur dessa kan sättas i samband med den massmediala diskursen i ämnet. Rapporten är i första hand en litteraturstudie. Men den innehåller också exempel och tolkningar från tre parintervjuer där paren har skiftande erf

Pancreatic pseudocysts often complicate the course of both acute and chronic pancreatitis. The management, if the pseudocysts are symptomatic, still remains a substantial clinical problem. Surgical drainage was prior to the introduction of ultrasound and CT more or less the treatment of choice. A vide variety of other treatments have, however, been described that aim to achieve at least as good sh

Moraxella catarrhalis is an airway pathogen whose role in infection has been increasingly recognized in recent years. Most authorities in this field now agree that M. catarrhalis causes significant morbidity and is not just a harmless commensal. The universal prevalence of BRO ?-lactamases in this pathogen is a serious concern. In addition, M. catarrhalis may be further propelled into a more promi
