Reconstructions and simulations disagree on whether the Holocene exhibited a long-term cooling or warming signal. Anthropogenic land-use could be an important forcing regionally, but available population-based estimates differ widely. We examine transient Holocene climate model simulations forced with three population-based disturbed-land reconstructions and compare this with a fourth scenario der
Due to the current fast-paced business environment, new approaches to product development (PD) have been requested. In that matter, the agile approach has gained interest among researchers and practitioners. Based on its positive results in the software industry, it has started to be adopted in the manufacturing industry. Nevertheless, there are factors that manufacturing companies must consider w
The demand for energy efficient heating solutions can be met by a new concept technology of induction heating. The concept technology relies on inductors built on litz wires moulded in soft magnetic composite. The aim of this article is to present and verify a hypothesis for greatly improved induction heating efficiency when modifying a traditional inductor design. The verification performed using
The paper presents the results of a comparative analysis of machinability and dynamic stability when turning a nickel-based superalloy with WRA tools in a conventional and prototype toolholders. The use of the prototype toolholder with a spatial structure is shown to significantly suppress vibrations during the machining and stabilize the process within the cutting speed range between 200 and 400
Multi-spectral lidar (light detection and ranging) techniques have been developed and employed in various environmental studies, ranging from concentration mapping of volcanic emissions to fluorescence imaging of historical monuments. In both absorption measurements of gaseous species and fluorescence imaging of stones, multiple wavelength excitation and multiple wavelength detection have been app
DNA evidence, linking perpetrators to crime scenes, is central to many legal proceedings. However, crime scene samples often contain extraneous substances that may interfere with the PCR-based forensic analysis, resulting in partial or negative DNA profiles. Extensive DNA purification may remove inhibitors, but involves the risk of DNA loss. In this work, pre-PCR processing was applied to improve
The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance since the energy use could decrease. There has been a lack of knowledge, models and tools for determining the life cycle cost (LCC) for an indoor climat
