Humans can easily generate more than 1000 W of heat during heavy exercise. This heat has to be transferred to the environment to stay in thermal equilibrium. During exercise in extreme cold, heat loss may exceed heat production, and clothing is necessary to prevent hypothermia. It will be shown how ISO …

Bij hittegolven wachten ouderen vaak lijdzaam af tot de hitte komt. In dit onderzoek is nagegaan of drie dagen acclimatisatie aan hitte bij oudere vrouwen helpt als voorbereiding voor als hitte toeslaat. Een groep jonge vrouwen heeft als controlegroep gefungeerd. Uit het onderzoek is gebleken dat drie …

Thermal comfort is determined by the combined effect of the six thermal comfort parameters: temperature, air moisture content, thermal radiation, air relative velocity, personal activity and clothing level as formulated by Fanger through his double heat balance equations. In conventional air conditioning …

The environmental impact of Synthetic Natural Gas (SNG) production from wood gasification is analysed, focusing on the comparison of two continuous processes (CO2 removal and Fuel-assisted hydrogen addition) to balance the gas mix for the methanation, and their coupling to an intermittent process (Full …

The increase in renewable energy sources will require an increase in the operational flexibility of the grid, due to the intermittent nature of these sources. This can be achieved for the gas and the electricity grid, which are integrated by means of power-to-gas and vice versa, by applying gas and other …

Presentatie, gehouden op 24 april op de ESEIA (European sustainability energy innovation alliance) conferentie aan de universiteit van Twente.

PowerMatching City. A unique smart grid project.In this presentation, the smart grid project 'PowerMatching City' is introduced. PowerMatching City is a living lab demonstration of the future energy system. In PowerMatching City the connected households are equipped with a mix of decentralized energy …

In this study we tested 39 Lactococcus lactis strains isolated from diverse habitats for their robustness under heat and oxidative stress, demonstrating high diversity in survival (up to 4 log units). Strains with an L. lactis subsp. lactis phenotype generally displayed more-robust phenotypes than strains …

Research has been done to improve the understanding the self-heat effect, due to power dissipation, of temperature-dependant resistors in the VSL water calorimeter. A custom measurement program has been written to be able to control and read out three Agilent 3458A digital multimeters (DMMs). With these …

Kipp & Zonen, based in Delft manufactures and develops atmospheric measurement instruments, including a scintillometer. Kipp & Zonen currently manufactures the large aperture scintillometer (LAS) MkII and previously manufactured the extra large aperture scintillometer (XLAS) MkI. A scintillometer can …
