  2. 1. The effect of climate on oak-based species interactions : annual number of leaf flushes and insect voltinism

    Author : Álvaro Gaytán; Ayco J. M. Tack; Karl Gotthard; Kailen A. Mooney; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate change; food webs; latitude; leaf flush; plant-based species interactions; Quercus robur; voltinism; Ecology and Evolution; ekologi och evolution;

    Abstract : Plants interact with a large diversity of organisms, including insects and microorganisms. These species interactions are strongly influenced by climate, as illustrated by the advances in plant and insect phenology in response to increasing temperatures. READ MORE

  4. 2. Frequency Optimization of Vibratory Rollers and Plates for Compaction of Granular Soil

    Author : Carl Wersäll; Stefan Larsson; Michael Mooney; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compaction; vibratory roller; frequency; resonance; vibration; sand; gravel; soil dynamics; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Vibratory rollers are commonly used for compaction of embankments and landfills. This task is time consuming and constitutes a significant part of most large construction and infrastructure projects. By improving the compaction efficiency, the construction industry would reduce costs and environmental impact. READ MORE

  5. 3. Mircostructure and rheological properties of concentrated tomato suspensions during processing

    Author : Elena Bayod; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheology; microstructure; morphology; flocs; tomato paste; ketchup; fibre suspensions; viscoelastic properties; particle size distribution; time dependency; network; yield stress; wall slip; Mooney; Cox-Merz rule; Tikhonov; tube viscometer; rotational viscometer; homogenisation; shearing;

    Abstract : Food processing comprises operations such as dilution (changing the concentration), homogenisation (changing the particle size), and subsequent pumping (shearing), among others. It is thus of great interest to gain a better understanding of the mechanisms governing the creation and disruption of structures during these engineering operations, and the way in which they are related to the textural and rheological properties of the material.

  6. 4. Truck tyre rolling resistance : Experimental testing and constitutive modelling of tyres

    Author : Jukka Hyttinen; Lars Drugge; Jenny Jerrelind; James Busfield; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Truck tyre; PRF; filler reinforced rubber; ambient temperature; rubber testing; parametrisation; Finite-element simulation; Lastbildäck; PRF; gummi; förstärkande fyllmedel; effekt av omgivningstemperatur; gummiprovning; parametrisering; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Global warming sets a high demand to reduce the CO2 emissions of vehicles. In the European Union heavy-duty road transports account for 6 % of the total greenhouse gases and one of the main factors affecting these emissions is related to the rolling resistance of tyres. READ MORE

  7. 5. Biomechanical Analysis of Fall Injuries using Finite Element Modeling

    Author : Pooya Sahandifar; Svein Kleiven; Viveca Wallqvist; Yunhua Luo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fall induced injury; finite element analysis; rubberized asphalt mixture; shock-absorbing pavement; hip fracture; elderly; sideways fall; whole-body model;

    Abstract : A fall is a serious health issue for the elderly. Among different fall types, the sideways fall is considered to be more severe concerning the injury outcome. READ MORE
