CBIs studie om innovationsledning
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- CBI har under andra halvåret 2010 och första halvåret 2011 genomfört en studie av innovationsledning hos 38 utvalda svenska företag inom tillverkning, IT och Telekom. Syftet var att undersöka hur företagen leder och organiserar innovation samt vilka utmaningar de står inför. Frågorna har besvarats av antingen VD eller en medlem i ledningsgruppen med insyn i företagets hantering av innovation.Resultatet visar att -de flesta företagen inte skiljer på radikal och inkrementell innovation-i många företag används ordet innovation för all produkt- och tjänsteutveckling-de flesta företag ser en ökning av innovationstakten inom sin respektive bransch-de flesta företag uttrycker att innovation är viktigt, samtidigt som få företag har innovationsfrågor bland sina tre största utmaningar-hälften av företagen använder någon form av rutin för att stärka sin förmåga att skapa nya produkter och tjänster, men endast ett fåtal använder flera olika rutiner-förstainnovationsföretagen (mindre, relativt nystartade företag) skiljer sig från de övriga i det att de är starkt innovationscentrerade-många företag välkomnar stöd från akademin, men endast ett fåtal önskar stöd att öka sin innovationsförmågaCBIs samtliga seniora forskare har genomfört intervjuerna.

Urban Cultures: Fallet Kommersen
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Urban Cultures: Fallet Kommersen (Case Kommersen) This project builds upon knowledge derived from our previous work with Urban Cultures (se Gillberg et al 2012), which was a summary of both theoretical (cultural) perspectives on the city as well as cultural everyday doings within the city. Our conclusion then, which is our point of departure now, was that urban cultures needed the city to be an enabling city. This time we want to further explore this topic by investigating the city in real life. Our intention is modest and based on the humble thought of a possibility to add some positive insights from adding culture – as a methodological and analytic perspective, a concept and an empirical given – into the mix of ingredients commonly associated with the notion of sustainability. One way of reaching the sustainable city is thought to be by making the city dense. Therefore one of the aims of this project is to investigate what the concept cultural densification would consist of and what it would mean to use it within city planning. To do so we have chosen the flea market Kommersen at Masthuggstorget, Gothenburg as our case study. We argue that markets, and in this case an urban flea market, are important phenomena that contribute to sustainable urban cultures in specific ways depending on particular market mechanisms, organizational features and socio-cultural dimensions of the flea market. In conclusions we present the concept of sustainable cultural densification defined as: urban cultures are drivers of complex processes of layering of values over time. These values could be seen as solutions to different problems residing in cities, and a lens through which to perceive of sustainable urbanity.

Effects on heart rate variability by artificially generated indoor nano-sized particles in a chamber study
- 2014
-
Ingår i: Atmospheric Environment. - : Elsevier BV. - 1352-2310. ; 88, s. 165-171

Tidskriftsartikel (refereegranskat)abstract
- Background: Airborne particles are associated with increased morbidity and mortality due to respiratory and cardiovascular diseases in polluted areas. There is a growing interest in nano-sized particles with diameter < 100 nm and their potential health effects. Heart rate variability (HRV) is a noninvasive method for cardiovascular risk prediction in high prevalent groups. Aim of study: The aim was to evaluate the impact of nano-sized indoor air particles on HRV for healthy and adult females. Methods: All exposures were performed as controlled chamber experiments with particle exposure from burning candles, terpene + ozone reactions or filtered air in a double-blind cross over design. Twenty-two healthy females were investigated during 10 min periods at different exposures and the reactivity in high frequency (HF) spectral band of HRV were computed. Results: Heart rate was unchanged from baseline values in all groups during all experimental settings. HF power of HRV tended to increase during exposure to particles from burning candle while particles from terpene + ozone reactions tended to decrease HF power. Conclusions: Exposure to nano-sized particles of burning candles or terpene + ozone reactions results in different patterns of heart rate variability, with signs of altered autonomic cardiovascular control. Practical implications: This study indicates that the HRV method may be used for information on physiological responses of exposure to different nano-sized particles and contribute to the understanding of mechanisms behind health effects of particle exposures.

- Inelastic x-ray scattering spectra excited at the 1s(-1) pi* resonance of gas phase O-2 have been recorded with an overall energy resolution that allows for well-resolved vibrational progressions. The nuclear wave packet dynamics in the intermediate state is reflected in vibrational excitations of the electronic ground state, and by fine-tuning the excitation energy the dissociation dynamics in the predissociative B' (3) Pi(g) final state is controlled.

- Abstract in Undetermined The aim of this study was to achieve a method to perform detailed characterization and human exposure studies of nanosized and nanostructured aerosol particles. The source chosen was mild steel, active gas, arc welding fume. The setup consisted of a generation chamber, where welding can be performed, connected to an airtight stainless steel 22 m(3) exposure chamber. Instrumentation, consisting of a tapered element oscillating microbalance, a scanning mobility particle sizer, and a sampler for electron microscopy and particle-induced X-ray emission analysis was connected to the stainless steel chamber. The feasibility of the system for human exposure studies was evaluated by exposing 31 human volunteers, in groups of three, to a test aerosol containing 1 mg/m(3) welding fumes and to conditioned, filtered air. The results show that an aerosol that accurately represents dilute welding fume exposures that occur in workplaces can be produced in a controlled manner, and that the experimental setup can be used for 6 h, double-blind, exposures of human subjects. Particle mass concentration levels could be varied from <5 mu g/m(3) to more than 1000 mu g/m(3). Fumes from metal active gas welding showed a unimodal size distribution with a mean mobility diameter of 160 nm, transmission electron microscopy showed aggregates with a clearly nanosized structure.

Realistic indoor nano-aerosols for a human exposure facility

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to achieve realistic levels of two different types of aerosols commonly abundant in indoor environments in an experimental chamber intended for human exposure studies and aerosol characterization. The aerosols chosen were particles from candle lights (in particle number dominated by inorganic water soluble particles) and from ozone-terpene reactions (organic particles). The aerosol generation and characterization system consisted of a controlled air tight stainless steel 22 m(3) chamber, to which the generation set-ups were connected. No air could enter or leave the chamber except through a conditioning system by which temperature, relative humidity and air exchange rate could be controlled. Candle smoke aerosol was generated from ten candles burning in a 1.33 m(3) glass and stainless steel chamber. The aerosol was diluted by clean air from the conditioning system before entering the chamber. Terpene vapor was generated by passing pure nitrogen through a glass bottle containing limonene oil. Ozone was generated by a spark discharge using pure O-2, and was added to the ventilation air flow downstream the inlet for terpene vapors and upstream the inlet to the chamber. Both aerosols were characterized with respect to number and mass concentrations, size distribution and chemical composition. Particle number concentration in the size range 10-650 nm could be varied from <10 cm(-3) to more than 900,000 cm(-3) (for candle smoke) or to more than 30,000 cm(-3) (for particles formed in a 160 ppb terpene/40 ppb ozone mixture). Furthermore, the set-ups were evaluated by, for each source, repeating the generation at six three-hour long events. For both aerosols repeatable generations at pre-determined concentration levels, that were stable over time, could be achieved. The results show that realistic concentrations of aerosols from real-world environments could be reproduced in a well-controlled manner and that this set-up could be used both for aerosol characterization and for human exposures.

An integrated review of concepts and initiatives for mining the technosphere: towards a new taxonomy

- Stocks of finite resources in the technosphere continue to grow due to human activity, at the expense ofdecreasing in-ground deposits. Human activity, in other words, is changing the prerequisites for mineralextraction. For that reason, mining will probably have to adapt accordingly, with more emphasis on theexploitation of previously extracted minerals.This study reviews the prevailing concepts for mining the technosphere as well as actual efforts to doso, the objectives for mining, the scale of the initiatives, and what makes them different from other reuseand recycling concepts. Prevailing concepts such as “urban mining,” however, are inadequate guides tothe complexity of the technosphere, as these concepts are inconsistently defined and disorganized, oftenoverlapping when it comes to which stocks they address. This review of these efforts and their potentialis therefore organized around a new taxonomy based on the umbrella concept technospheric mining,defined as the extraction of technospheric stocks of minerals that have been excluded from ongoinganthropogenic material flows.An analysis on the basis of this taxonomy shows that the prevailing mining initiatives are generallyscattered and often driven by environmental factors, in which metal recovery is viewed as an additionalsource of revenue. However, development of technology, specialized actors and new business modelsand policy instruments, could lead to technospheric mining operations becoming a profit-drivenbusiness.

Konferensbidrag (refereegranskat)abstract
- This paper presents a method and software for interfacing Systems Modeling Language (SysML) and Sequence Planner Language (SPL). Exchange of information between different software tools is of major interest for modern manufacturing industries from early design to final implementation. SysML, with its structure as a common platform, can then be interfaced with other domain-specific modeling tools to achieve information exchange. This paper presents a method to interface SysML with a recently introduced language for operation sequences called Sequence Planner Language (SPL). By this method, necessary information from behavioral constructs of SysML model are extracted and structured in SPL. This language, being a formal, graphical language,can be used to formally verify the system for any blocking states. An academic and an industrial model developed in SysML are tested using the interface implementation and the results show that information from SysML can be visualized in SPL and formally verified to have no blocking states.

- Mg-chelatase catalyzes the first committed step of the chlorophyll biosynthetic pathway, the ATP-dependent insertion of Mg2+ into protoporphyrin IX (PPIX). Here we report the reconstruction using single-particle cryo-electron microscopy of the complex between subunits BchD and BchI of Rhodobacter capsulatus Mg-chelatase in the presence of ADP, the nonhydrolyzable ATP analog AMPPNP, and ATP at 7.5 angstrom, 14 angstrom, and 13 angstrom resolution, respectively. We show that the two AAA+ modules of the subunits form a unique complex of 3 dimers related by a three-fold axis. The reconstructions demonstrate substantial differences between the conformations of the complex in the presence of ATIP and ADP, and suggest that the C-terminal integrin-I domains of the BchD subunits play a central role in transmitting conformational changes of BchI to BchD. Based on these data a model for the function of magnesium chelatase is proposed.

Techno-economics of carbon preserving butanol production using a combined fermentative and catalytic approach
- 2014

Tidskriftsartikel (refereegranskat)abstract
- This paper presents a novel process for n-butanol production which combines a fermentation consuming carbon dioxide (succinic acid fermentation) with subsequent catalytic reduction steps to add hydrogen to form butanol. Process simulations in Aspen Plus have been the basis for the techno-economic analyses performed. The overall economy for the novel process cannot be justified, as production of succinic acid by fermentation is too costly. Though, succinic acid price is expected to drop drastically in a near future. By fully integrating the succinic acid fermentation with the catalytic conversion the need for costly recovery operations could be reduced. The hybrid process would need 22% less raw material than the butanol fermentation at a succinic acid fermentation yield of 0.7 g/g substrate. Additionally, a carbon dioxide fixation of up to 13 ktonnes could be achieved at a plant with an annual butanol production of 10 ktonnes

Sun-Induced Nonsynonymous p53 Mutations Are Extensively Accumulated and Tolerated in Normal Appearing Human Skin

Tidskriftsartikel (refereegranskat)abstract
- Here we demonstrate that intermittently sun-exposed human skin contains an extensive number of phenotypically intact cell compartments bearing missense and nonsense mutations in the p53 tumor suppressor gene. Deep sequencing of sun-exposed and shielded microdissected skin from mid-life individuals revealed that persistent p53 mutations had accumulated in 14% of all epidermal cells, with no apparent signs of a growth advantage of the affected cell compartments. Furthermore, 6% of the mutated epidermal cells encoded a truncated protein. The abundance of these events, not taking into account intron mutations and mutations in other genes that also may have functional implications, suggests an extensive tolerance of human cells to severe genetic alterations caused by UV light, with an estimated annual rate of accumulation of similar to 35,000 new persistent protein-altering p53 mutations in sun-exposed skin of a human individual.

Intramolecular soft modes and intermolecular interactions in liquid acetone
- 2011

Tidskriftsartikel (refereegranskat)abstract
- Resonant inelastic x-ray scattering spectra excited at the O1s−1π* resonance of liquid acetone are presented. Scattering to the electronic ground state shows a resolved vibrational progression where the dominant contribution is due to the C-O stretching mode, thus demonstrating a unique sensitivity of the method to the local potential energy surface in complex molecular systems. For scattering to electronically excited states, soft vibrational modes and, to a smaller extent, intermolecular interactions give a broadening, which blurs the vibrational fine structure. It is predicted that environmental broadening is dominant in aqueous acetone.

To prospect an urban mine - assessing the metal recovery potential of infrastructure "cold spots" in Norrkoping, Sweden

- In conventional mining, prospecting methods are used to increase the degree of certainty with regard to the stock of metals. Similarly, prospecting in terms of "urban mining" aims to increase the information about metal stocks available for recovery in the built environment. Infrastructure systems, such as for power supply and heating, are rich in copper, aluminum and iron (including steel). For a number of reasons, pipes and cables remain in the ground after being taken out of use or disconnected. This is also true for entire obsolete systems. In this paper, these infrastructures "cold spots" are viewed as hibernating stock with a significant potential for urban mining. less thanbrgreater than less thanbrgreater thanThe infrastructure systems for AC and DC power, telecommunication, town gas and district heating in the city of Norrkoping, Sweden, have been quantified and spatially allocated with a GIS-based approach of Material Flow Analysis (MFA). About 20% of the total stock of aluminum and copper in these systems is found to be in hibernation. The findings also indicate that cables have been disconnected to a larger extent than pipes. As an example, cables for DC power, taken out of use in the late 1930s yet still in the ground, consist of 230 tonnes of copper. The results illustrate a clear tendency for larger stocks of hibernating copper and aluminum to be found in the central rather than the outer parts of the city. A reverse, ring-like pattern is true for iron, mostly because the central parts of the town gas pipes are used for fiber optics. less thanbrgreater than less thanbrgreater thanParticular focus has been placed on the industrial area of Sodra Butangen, which is slated for redevelopment and re-zoning from industrial to residential. Since the ground will be dug up for sanitation purposes anyway, the entire metal stock can be taken into prospecting consideration. Analysis shows that the chances of finding aluminum here are 28 times higher than in the rest of the city. less thanbrgreater than less thanbrgreater thanWe argue for an increased MFA focus on the heterogeneous complexity found in the details of the specific locale, rather than striving for generalized assumptions about the broader picture. In doing so, MFA could very well provide a tool for a future business line of urban mining of hibernating metal stocks.
