- The Sub-millimetre and Millimetre Radiometer (SMR) is the main instrument on the Swedish, Canadian, Finnish and French spacecraft Odin. It consists of a 1.1 metre diameter telescope with four tuneable heterodyne receivers covering the ranges 486-504 GHz and 541-581 GHz, and one fixed at 118.75 GHz together with backends that provide spectral resolution from 150 kHz to 1 MHz. This Letter describes the Odin radiometer, its operation and performance with the data processing and calibration described in Paper II.

- Context: Molecular oxygen, O2, has been expected historically to be an abundant component of the chemical species in molecular clouds and, as such, an important coolant of the dense interstellar medium. However, a number of attempts from both ground and from space have failed to detect O2 emission.Aims: The work described here uses heterodyne spectroscopy from space to search for molecular oxygen in the interstellar medium. Methods: The Odin satellite carries a 1.1 m sub-millimeter dish and a dedicated 119 GHz receiver for the ground state line of O2. Starting in 2002, the star forming molecular cloud core ρ Oph A was observed with Odin for 34 days during several observing runs.Results: We detect a spectral line at v_LSR =+3.5 km s-1 with Δ v_FWHM=1.5 km s-1, parameters which are also common to other species associated with ρ Oph A. This feature is identified as the O2 (NJ = 11 - 1_0) transition at 118 750.343 MHz.Conclusions: The abundance of molecular oxygen, relative to H{2} , is 5 × 10-8 averaged over the Odin beam. This abundance is consistently lower than previously reported upper limits.Based on observations with Odin, a Swedish-led satellite project funded jointly by the Swedish National Space Board (SNSB), the Canadian Space Agency (CSA), the National Technology Agency of Finland (Tekes) and Centre National d'Étude Spatiale (CNES). The Swedish Space Corporation has been the industrial prime contractor and also is operating the satellite. Appendix A is only available in electronic form at http://www.aanda.org

Tidskriftsartikel (refereegranskat)abstract
- The main question raised in this article is whether there are any differences between the work activities of managers in small firms primarily operating on an international market and those managing firms doing business on a domestic market. If so, what are these differences, and what do they tell us about the internationalization of small firms? The comparative method used here is based on multiple approaches including interviews, diary studies, and direct observations. The conclusions indicate that managers in small international firms are more proactive in their networking behavior, delegate operative activities and devote more time to planned strategic activities connected with their international expansion than managers in other small firms.

Tidskriftsartikel (refereegranskat)abstract
- A comprehensive model is developed for complete methane oxidation over supported palladium. The model is based on first-principles microkinetics and accounts for mass and heat transport in a porous catalytic layer. The turnover frequency (TOF) is simulated for wet exhaust gas compositions, exploring the effects of temperature and total pressure on the TOF. Three different temperature regimes are identified each with different dependency on the total pressure. The regimes originate from temperature and pressure dependent coverages of carbon dioxide and water, which are the most abundant surface species hindering methane dissociation at low temperatures. The TOF is controlled by surface kinetics below 400 °C whereas above 500 °C and up to 8 atm, internal mass transport is controlling. A combination of kinetics, external and internal mass transport controls the TOF at other reaction conditions. The physically meaningful model paves the way for extrapolation and optimization of catalyst design parameters for high catalytic efficiency.

Multiscale reactor modelling of total pressure effects on complete methane oxidation over Pd/Al2O3

Tidskriftsartikel (refereegranskat)abstract
- A two-dimensional multiscale model is developed for complete methane oxidation in a continuous flow reactor. The model considers mass and heat transfer for a porous alumina supported palladium catalyst coated on a ceramic monolith substrate and the surface kinetics are described by a first-principles microkinetic model for complete methane oxidation over PdO(101). The temperature dependent conversion for a synthetic exhaust gas composition shows a delayed ignition but a higher conversion at elevated temperatures when the total pressure is increased from 1 to 10 atm. The simulations reveal a temperature and total pressure dependent operating point where the methane conversion is maximized. Analysis of the kinetics shows that the reaction is suppressed by bicarbonates, hydroxyl species and water originating from adsorbed carbon dioxide and water from the gas phase. The reaction order with respect to water and carbon dioxide at 1 atm is -0.94 and -0.99, respectively, and decreases with increasing total pressure. The developed model paves the way for exploring how design parameters and reaction conditions influence the complete methane oxidation reaction.

A framework for raw materials management in process industries
- 2013
-
Konferensbidrag (refereegranskat)abstract
- Firms in the process industries manipulate materials properties to produce upgraded raw materials for applications and products upstream in a supply chain. About 25% of the most research intensive firms in the world belong to the process industries, so proper management of raw materials is a key concern for many firms. This article explores the concept of “raw materials management”. By studying the current world leader in powder metallurgy, the Höganäs Corporation, the article describes the external and internal factors impacting how raw materials are managed, and how raw material issues affect different aspects of firm performance. Managerial implications are presented elaborating three key-areas that firms should deal with when developing a strategic approach to raw materials management.

Critical success factors in early new product development : a review and a conceptual model
- 2018
-
Ingår i: The International Entrepreneurship and Management Journal. - New York : Springer-Verlag New York. - 1554-7191 .- 1555-1938. ; 14:2, s. 411-427

Tidskriftsartikel (refereegranskat)abstract
- The literature on the front end in the New Product Development (NPD) literature is fragmented with respect to the identification and analysis of the factors that are critical to successful product development. The article has a two-fold purpose. First, it describes, analyses, and synthesizes those factors through a literature review of the research on the front end in NPD. Second, it conceptualizes a framework that features two types of success factors: foundational success factors (common to all the firm’s projects) and project-specific success factors (appropriate for the firm’s individual projects). The article makes recommendations for the management of this important phase of product development, discusses limitations of relevant previous research, and offers suggestions for future research. The article makes a theoretical contribution with its analysis and synthesis of the reasons for success in front-end activities and a practical contribution with its conceptual framework that can be used as an analytical tool by firms and their product managers. © 2017 The Author(s)

- PurposeThe purpose of this paper is to explore the relationship between HRM practices and entrepreneurial orientation (EO) in large established firms. More specifically, the purpose is to add to the understanding of the influence of HRM practices on EO.Design/methodology/approachAn e-mail survey was distributed to a sample of Swedish and German manufacturing firms in high-tech and medium high-tech manufacturing industries, and firms in knowledge-intensive services sectors, with more than 250 employees. In total, 810 surveys were distributed, with a response rate of 12.7 per cent. Findings - The results show that an emphasis on entrepreneurial aspects leads to an increased EO only in the case of training and development. A conclusion therefore is that it seems difficult to recruit personnel or to use appraisal and rewards as to create EO on a firm level.Practical implicationsThe study indicates that firms aiming to increase their EO should make sure to emphasize entrepreneurial aspects during staff training and development activities. Originality/value - This empirical study paves the way towards a better understanding of the link between HRM practices and EO. The results should be of interest for both HR professionals and researchers interested in understanding this important relationship.

From Preliminary Ideas to Corroborated Product Definitions : Managing the Front End of New Product Development
- 2012

Tidskriftsartikel (refereegranskat)abstract
- Front-end activities largely influence the outcomes of new product development processes, because it is here that firms create new ideas, give them direction, and set them in motion. We show that the front end can be understood as comprising three core activities: idea/concept development, idea/concept alignment, and idea/concept legitimization, which allow firms to create corroborated product definitions. The paper provides important implications for managers interested in front-end management, and devote specific attention to the differences between incremental and radical front end development and to the front end in the light of increasingly open innovation processes.
