Eye-tracking test design influences the relationship between gazing behaviour and evaluation decision

Workflow of the choosing, ranking, and rating task Abbildung 1. Ablauf der Auswahl-, Ranking- und Bewertungsaufgaben A pre-test was conducted with ten consumers before the main experiment, to make sure that the procedure and its instruction were clear and easy to understand for untrained participants. 2.6 Eye-tracking technique The Tobii-T60 eye tracker and Tobii studio software (version 3.0.5, Tobii Technology AB, Sweden) were used to gather and analyse data on the gazing behaviour of consumers. Test pictures were presented on a 17-inch-thin-film

Aging concrete structures: a review of mechanics and concepts

initiation of corrosion, that is, the time from concrete casting to the moment when the reinforcement is no longer passivated, such as due to the effect of chlorides. In general, steel within concrete is protected against corrosion through a thin film of oxidation products, which form due to the high alkalinity of the surrounding concrete. Corrosion commences as soon as the pH-value drops below roughly 9.0 , caused by carbonation, chloride ingress, or physical damage. The quantity controlling the progress of corrosion is the so-called corrosion rate. This variable is

Indoor air pollution and the contribution of biosensors

resonance frequency due to mass loading, has shown high sensitivity for chemicals and has potential application related to artificial noses ( 75 ). For example, piezoelectric substrate modified with SnO2 thin films was used for development hydrogen gas surface acoustic wave (SAW) sensors ( 76 ). In this study, enhancement of the sensor performance was proceed by creating bi-layer sensing film made from SnO2 and highly dispersed palladium nanoparticle layers. Also, SAW based sensors were used to monitor methanol, diesels and benzenes ( 77 ), nitrogen dioxides ( 78

Corrosion inhibition of iron surfaces with phosphatidic acid

for layer thickness was conducted in Thin Film Companion (TFC) software (Semiconsoft). Results Benchmarking the acidic corrosion of the iron surface To establish a reference, corrosion of iron in acetic acid was monitored using QCM. Experiments were performed with 0.1M and 0.01M acetic acid at 25 °C, and the rates of iron dissolution were established. Fig. 1 . shows and example of the experimental results, the effect of 10 mM acetic acid on the iron surface at 25 °C. After an initial period (~8 min) linear increase of the frequency from zero to 2.3 kHz is

Presence of Trypanosome Species and Anemic Status of Dogs in Zuru, Nigeria

Abstract

The aim of this research is to study the presence and prevalence of trypanosome species in local dogs between January and July, 2010 in the Zuru area of Kebbi State, Nigeria.Standard trypanosome detection methods comprising of wet blood films, thin films and microhaematocrit centrifugation technique were used to detect trypanosomes; while the degree of anemia was determined through the use of FAMACHA® eye colour chart and packed cell volume values. A total of 567 dogs were enumerated in fourteen locations within the study area out of which 192 (33.7%) were randomly examined and 4 (2.08%) were positive for the presence of trypanosomes. All positive samples morphologically belong to the Trypanosoma brucei group. The obtained PCV values showed that 50 (26.04%) dogs were anemic, while the FAMACHA® detected anemia status of varying degrees in 104 (77%) sampled dogs.These findings are significant as this is the first time that the trypanosome infection will be reported in dogs from the study area. This study establishes the presence of Trypanosoma brucei group in the study area, which is of zoonotic and economic importance.

Study of Cigarette Smoke Filtration by Means of the Scanning Electron Microscope

Abstract

The method developed by Peck (8) for observing smoke deposits on cigarette filters with the scanning electron microscope was extended to two techniques to determine how the particulate phase of smoke is deposited on celluIose acetate filters and on individual cellulose acetate fibers.

Technique A: Immediately after the smoke particles were deposited on the fibers, the filter was exposed to methyl 2-cyanoacrylate vapour; the methyl 2 cyanoacrylate monomer polymerized rapidly and formed a very thin film (0.05 µ thick) over the partially volatile particles so they could be examined in the vacuum chamber of the scanning electron microscope. This technique was used to observe smoke deposits on single fibers oriented either parallel or perpendicularly to the smoke stream.

Technique B: Methyl 2-cyanoacrylate vapour was drawn into a mixing chamber in front of the filter as each puff of smoke was taken. The monomer coated the particles and polymerized. The coated particles were subsequently trapped by the fibers and observed with the scanning electron microscope.

From techniques A and B, it was observed that single fibers oriented parallel to the smoke stream showed a heavy deposition of small particles (<< 0.1 µ in diameter). This observation qualitatively confirms the theory that diffusion is one of the predominant mechanisms of filtration. Relatively smalI numbers of large smoke particles (> 0.5 µ in diameter) were trapped by single fibers oriented perpendicularly to the smoke stream. These large particles were trapped by interception on fibers which were perpendicular to the smoke path. The edge of each Y-cross-section fiber, where interception is most likely to occur, was more heavily coated than other parts of the fiber. All of the large particles in a 28- × 45-µ area on a single fiber oriented perpendicularly to the smoke stream were counted. The total number of particles on the fiber were calculated and compared to the amount expected from the totaI number of particles per puff, the fraction of particles larger than 0.5 µ, and the single fiber efficiency. Good agreement between the experimental and calculated values was obtained.
