Effectiveness of a light-weight ice-vest for body cooling in fire fighter's work

Syftet med denna undersökning var att bestämma en 1 kg isvästs kylverkan på kroppen vid brandmansarbete. Testerna genomfördes i en klimatkammare, i en container med extrem strålningsvärme och i ett rökdykningshus med värme och tungt arbete. Den faktiska kylverkan mättes också med en termisk docka. Fyra erfarna brandmän deltog i försöken. I alla tester bar försökspersonerna standardklädsel för branThe aim of the present study was to examine the effects of wearing a light-weight ice-vest (1kg, water) on physiological and subjective responses in fire fighter’s work. The experiments were carried out in a climatic chamber, in a container under extreme radiant heat, and during simulated smoke-diving. In addition, the physical cooling effect of the ice-vest was measured with a thermal mannequin.

Ad-hoc composition of pervasive services in the PalCom architecture

We present an architecture supporting ad-hoc composition of pervasive services, an open-source framework that implements it, and the key design principles behind it. The architecture focuses on direct human interaction, supporting combination of devices and services that are not explicitly designed to work together. The focus is on local networks, but extension is possible to wide area networks, i

The significance of form elements: a study of representational content of design sketches

The purpose of this paper is to understand the significance of form elements through the interpretations of design sketches. These interpretations are provided by designers themselves interpreting expressive characteristics of car images, and by students interpreting the sketches of designers' morphing sequences. In the experimental investigation of the sketching process through morphing sequence

The Plasma Membrane H+-ATPase - Identification of a 14-3-3 binding motif

The P-type plasma membrane H+-ATPases form a group of proteins only found in plants and fungi. The pumping of protons across the plasma membrane, energized by ATP hydrolysis, creates an electrochemical gradient that is essential for solute transport and internal pH regulation. The H+-ATPase genes are present as multigene families in the genomes of higher plants and all cell types investigated expr

Sufficient Conditions for Dynamic Stabilization of 3-State Moore-Greitzer Compressor Model

We consider the classical 3-state Moore-Greitzer model, which is commonly used for approximating dynamics of deviations of flow and pressure variables in an axial compressor from their nominal steady-state values. The linearization of the nonlinear system is not controllable and, therefore, even local asymptotic stability cannot be achieved using methods of linear control theory. We propose a fami

Euclidean structure from uncalibrated images

A number of recent papers have demonstrated that camera “self-calibration” can be accomplished purely from image measurements, without requiring special calibration objects or known camera motion. We describe a method, based on self-calibration, for obtaining (scaled) Euclidean structure from multiple uncalibrated perspective images using only point matches between views. The method is in two stag

COOLED PLATE TESTS ON TEXTILE MATERIALS IN SIMULATED COCKPIT UNDER “SOLAR RADIATION”

This study investigated if clothing material with reflective properties has an effect on heat gain in pilot, specifically, under solar radiation. Two materials, conventional pilot suit material (Old) and material coated with coldblack® (New, Schoeller Technologies AG, Switzerland) were tested over variety of underwear layers and in a box simulating cockpit. A hot plate was used to measure textile

Colonization processes of soil fauna and mycorrhizal fungi

Colonization consists of two parts, a dispersal phase followed by establishment and reproduction at a new site. Dispersal behaviour influences survival and the access to resources and mates of individuals and is thus closely linked to an organism's fitness. The dispersal ability of two collembolan species, Protaphorura armata and Folsomia fimentaria, was determined in a laboratory experiment. The
