- 2021
-
In: Future Foods. - : Elsevier. - 2666-8335. ; 4, s. 1-8
-
Journal article (peer-reviewed)abstract
- The objective of this study was to evaluate sensory perception and consumers’ attitude and liking of products with different textures, crisps and pâtés, with added mealworm ingredient in different amounts. By addition of mealworm ( Tenebrio molitor L. ) in the crisps, the brittleness increased. However, an increase in mealworm also increased the darkness. Adding mealworms to pâté reduced the odour and flavour of vegetable and increased the flavour of cinnamon and pepper as well as the oily texture. There was no significant difference in total liking between 10 and 30% addition of mealworm, nor between 0 and 10% addition, in any of the two products. The crisps received higher liking score than the pâtés. Thus, there is also a much higher probability that a customer would buy insect crisps than insect pâté. Environmental sustainability and sensory properties were shown to be the main reasons for buying foods with added insect ingredients.

The Fourteenth Data Release of the Sloan Digital Sky Survey : First Spectroscopic Data from the Extended Baryon Oscillation Spectroscopic Survey and from the Second Phase of the Apache Point Observatory Galactic Evolution Experiment
- 2018
-
In: Astrophysical Journal Supplement Series. - : IOP Publishing Ltd. - 0067-0049 .- 1538-4365. ; 235:2

Journal article (peer-reviewed)abstract
- The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since 2014 July. This paper describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release Fourteen or DR14). This release makes the data taken by SDSS-IV in its first two years of operation (2014-2016 July) public. Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey; the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data-driven machine-learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from the SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS web site (www.sdss.org) has been updated for this release and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020 and will be followed by SDSS-V.

The Fifteenth Data Release of the Sloan Digital Sky Surveys : First Release of MaNGA-derived Quantities, Data Visualization Tools, and Stellar Library
- 2019
-
In: Astrophysical Journal Supplement Series. - : Institute of Physics Publishing (IOPP). - 0067-0049 .- 1538-4365. ; 240:2
-
Journal article (peer-reviewed)abstract
- Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years of operation (2014 July-2017 July). This is the third data release for SDSS-IV, and the 15th from SDSS (Data Release Fifteen; DR15). New data come from MaNGA-we release 4824 data cubes, as well as the first stellar spectra in the MaNGA Stellar Library (MaStar), the first set of survey-supported analysis products (e.g., stellar and gas kinematics, emission-line and other maps) from the MaNGA Data Analysis Pipeline, and a new data visualization and access tool we call "Marvin." The next data release, DR16, will include new data from both APOGEE-2 and eBOSS; those surveys release no new data here, but we document updates and corrections to their data processing pipelines. The release is cumulative; it also includes the most recent reductions and calibrations of all data taken by SDSS since first light. In this paper, we describe the location and format of the data and tools and cite technical references describing how it was obtained and processed. The SDSS website (www.sdss.org) has also been updated, providing links to data downloads, tutorials, and examples of data use. Although SDSS-IV will continue to collect astronomical data until 2020, and will be followed by SDSS-V (2020-2025), we end this paper by describing plans to ensure the sustainability of the SDSS data archive for many years beyond the collection of data.

Modelling energy efficiency and carbon dioxide emissions in energy-intensive industry under stringent CO2 policies: Comparison of top-down and bottom-up approaches and evaluation of usefulness to policy makers
- 2009
-
In: Proceedings of eceee 2009 summer study. - 9789163344541 ; , s. 1181-1191
-
Conference paper (peer-reviewed)abstract
- The question of how different climate policies will influence carbon dioxide (CO2) emissions in the energy-intensive industry is complex. It is not obvious that increased costs for emitting CO2 will lead to investments in new, low-emission technologies, since the energy-intensive industry is very capital intensive, and reduced CO2 emissions beyond a certain point require large investments and possibly also radical process changes. Traditionally, either top-down or bottom-up models have been used to analyze the influence of specific policies on energy efficiency and CO2 emissions in industry. Bottom-up models describe technologies in detail, but are not realistic in their characterization of corporate decision-making, e.g., how businesses select technologies and make investments, and fail to depict macro-economic equilibrium feedbacks. Top-down models, in contrast, address these deficiencies by representing macro-economic feedbacks and by estimating parameters of technological change from observations of aggregate market responsiveness to cost changes. However, since top-down models lack technological detail, they are weak in assessing the use of new, low-emission technology. Because of these methodological differences, top-down and bottom-up models often make divergent cost predictions, and consequently suggest different policies, for meeting climate targets. This methodological divide has stimulated exploration of hybrid approaches that integrate the technological explicitness of bottom-up models with the micro-economic realism and macro-economic feedbacks of top-down models. To better understand the dynamics and policy responses of industry, such methods and models need to be further developed and applied. In this paper we analyse and compare top-down, bottom-up, and integrated (hybrid) approaches that have been used for evaluating potentials for CO2 emissions reductions and CO2 policy analysis in energy-intensive industry. We also evaluate the usefulness of these approaches and models to policy and decision makers.

Emulsion Condensation Polymerization in Dispersed Aqueous Media. Interfacial Reactions and Nanoparticle Formation
- 2013
-
In: Macromolecules. - : American Chemical Society (ACS). - 0024-9297 .- 1520-5835. ; 46:22, s. 9104-9113
-
Journal article (peer-reviewed)abstract
- The polycondensation of polyesters from C-12 monomers at 95 degrees C in aqueous o/w emulsions, stabilized by acidic surfactants, has been studied in detail with a range of methods during the course of the reaction, resulting in a better understanding of the underlying reaction mechanisms. Comparisons of different surfactants, and effects of added NaCl, demonstrate that the reaction site is located at the interface between the hydrophobic core of the emulsion droplets and the surrounding water and that the reaction rate is dependent on the local concentration of oxonium ions at the reaction site. The equilibrium conversion achieved at long reaction times is, however, independent of the choice of surfactant or addition of salt, and the state of thermodynamic equilibrium is discussed thoroughly. Interestingly, a fraction of numerous "nanoparticles" (droplets in the size range <= 100 nm) have been found to develop in addition to the original fraction of droplets in the 10 mu m size range. It is suggested that these nanoparticles are formed when monomers dissolved in the aqueous phase undergo an acid-catalyzed reaction to generate water-insoluble oligomers. Once the nanoparticles are formed, the reactions in them proceed with a reaction mechanism similar to emulsion polymerization.

Switchable presentation of cytokines on electroactive polypyrrole surfaces for hematopoietic stem and progenitor cells
- 2018
-
In: Journal of Materials Chemistry B. - Cambridge : Royal Society of Chemistry. - 2050-750X .- 2050-7518. ; 6:28, s. 4665-4675

Journal article (peer-reviewed)abstract
- Hematopoietic stem cells are used in transplantations for patients with hematologic malignancies. Scarce sources require efficient strategies of expansion, including polymeric biomaterials mimicking architectures of bone marrow tissue. Tissue microenvironment and mode of cytokine presentation strongly influence cell fate. Although several cytokines with different functions as soluble or membrane-bound mediators have already been identified, their precise roles have not yet been clarified. A need exists for in vitro systems that mimic the in vivo situation to enable such studies. One way is to establish surfaces mimicking physiological presentation using protein-immobilization onto polymer films. However these films merely provide a static presentation of the immobilized proteins. It would be advantageous to also dynamically change protein presentation and functionality to better reflect the in vivo conditions. The electroactive polymer polypyrrole shows excellent biocompatibility and electrochemically alters its surface properties, becoming an interesting choice for such setups. Here, we present an in vitro system for switchable presentation of membrane-bound cytokines. We use interleukin IL-3, known to affect hematopoiesis, and show that when immobilized on polypyrrole films, IL-3 is bioavailable for the bone marrow-derived FDC-P1 progenitor cell line. Moreover, IL-3 presentation can be successfully altered by changing the redox state of the film, in turn influencing FDC-P1 cell viability. This novel in vitro system provides a valuable tool for stimuli-responsive switchable protein presentation allowing the dissection of relevant mediators in stem and progenitor cell behavior.

The Effects of Wind Power on Human Interests : A Synthesis
- 2013
-
Reports (other academic/artistic)abstract
- PrefaceThere is a great need for knowledge concerning the impacts of wind power on humans, landscapes, the marine environment, birds, bats and other mammals.Previous studies of these environmental impacts have lacked an overall view of the effects. This has led to deficiencies in the processes surrounding the establishment of new wind farms. Vindval is a knowledge programme undertaken as a collaboration between the Swedish Energy Agency and the Swedish Environmental Protection Agency. Its aim is to gather and communicate scientific knowledge about the impacts of wind power on people and the natural environment. The programme continues until 2013.Vindval comprises some 30 individual research projects, together with four synthesis projects. Syntheses are prepared by experts, who compile and assess overall research results and experience regarding the effects of wind power in four different areas – humans, birds/bats, marine life and terrestrial mammals.The results of this research and synthesis work will provide a basis for environmental impact assessments and for the planning and permitting processes associated with wind power installations. Vindval requires high standards in the review and approval of research proposals, in order to ensure high-quality reports. The same high standards apply to the reporting, approval and publication of research results from the projects.This report was written by Johanna Bengtsson Ryberg, Gösta Bluhm, Karl Bolin, Bosse Bodén, Kristina Ek, Karin Hammarlund, Marianne Henningsson, Inga-Lena Hannukka, Carina Johansson, Sofia Jönsson, Sanna Mels, Tom Mels, Mats Nilsson, Erik Skärbäck, Patrik Söderholm, Åsa Waldo, Ingegärd Widerström, Niklas Åkerman.This report is a translation of the previous report in Swedish “Vindkraftens påverkan på människors intressen” (Naturvårdsverket report no 6497). Translated by Sofia Jönsson.The contents of the report are the responsibility of the authors.

Drivers of changing urban flood risk : A framework for action
- 2019
-
In: Journal of Environmental Management. - : Elsevier. - 0301-4797 .- 1095-8630. ; 240, s. 47-56
-
Journal article (peer-reviewed)abstract
- This study focuses on drivers for changing urban flood risk. We suggest a framework for guiding climate change adaptation action concerning flood risk and manageability in cities. The identified key drivers of changing flood hazard and vulnerability are used to provide an overview of each driver's impact on flood risk and manageability at the city level. We find that identified drivers for urban flood risk can be grouped in three different priority areas with different time horizon. The first group has high impact but is manageable at city level. Typical drivers in this group are related to the physical environment such as decreasing permeability and unresponsive engineering. The second group of drivers is represented by public awareness and individual willingness to participate and urbanization and urban sprawl. These drivers may be important and are manageable for the cities and they involve both short-term and long-term measures. The third group of drivers is related to policy and long-term changes. This group is represented by economic growth and increasing values at risk, climate change, and increasing complexity of society. They have all high impact but low manageability. Managing these drivers needs to be done in a longer time perspective, e.g., by developing long-term policies and exchange of ideas.
