[en] The morpheme nano in languages such as Swedish and English is a constituent of many words. This article linguistically analyses the meaning potential of nano by focusing on word use in a Swedish newspaper corpus comprising 2,564 articles (1.6 million words) covering a 22-year period (1988–2010). Close to 400 word forms having nano as a constituent have been identified and analyzed. The results suggest that nano covers a broad and heterogeneous conceptual field: (i) as a prefix of the SI system; (ii) in relation to the scientific activities of nanoscience and nanotechnology, including their sub-processes and actors; and (iii) in relation to objects. The identified meanings of nano, besides the standard definition (i.e. ‘billionth part’ in relation to SI units), are ‘operating at the nanometre level’ in relation to activities and their actors and ‘nanometre sized’ and ‘nanotechnological’ in relation to objects; in addition, the less precise and non-technical meaning ‘very small’ is identified. We discuss the implications of the findings for a hypothesis about media influence on public understanding of technology, suggesting that repeated findings in Europe and the USA of little self-reported understanding and knowledge of nanotechnology or nanoscience among the public make sense in light of the polysemy of nano reflected in its broad variety of verbal forms and usages.

[en] A network of four stations covering southeastern Sweden has been operated for the period Oct 1, 1986 - Mar 31, 1987. Three events were aftershocks to the strong Skoevde event, 860714, ML=4.5. This made it necessary to include the Skoevde main event together with a couple of earlier aftershocks in the analysis presented in this report. Thus the present study gives 10 new earthquake mechanisms. Three of these events are in the range ML=3.5-4.5. Of the earlier about 170 earthquake mechanisms available for southern Sweden the largest is ML=3.2. The earthquakes of the present study thus give significant new information about Swedish seismic activity. (orig./DG)

[en] This standard gives a survey of norms for nuclear measuring instruments beta-, gamma- and x-radiation. Included are: 1. Normes in Swedish. 2. International recommendations published by the International Electrotechnical commission, IEC, which are valid as Swedish standards Translations into Swedish of these recommendations do not exist, but they are available in English and French in the IEC publications. 3. Information on other norms. (K.K.)

[en] Swedish nuclear power plant personnel are trained locally at the plants and at a simulator center. The local on-site training includes classroom systems and theory as well as on-the-job training. Compact simulators are used to demonstrate and reinforce understanding of basic principles such as fluid flow, heat transfer, thermodynamics and reactor operation. Additional training is conducted at the Studsvik simulator training center for control room personnel. It consists of initial qualifications and annual retraining. 1 fig

[en] This conference paper discusses the role of pellets in the use of bioenergy in Sweden. Pellets (P) have many advantages: (1) P are dry and can be stored, (2) P create local jobs, (3) P burn without seriously polluting the environment, (4) P are made from domestic and renewable resources, (5) P have high energy density, (6) P fit well in an energy system adapted to nature, (6) P are an economical alternative, both on a small scale and on a large scale. Pellets are more laborious to use than oil or electricity and require about three times as much storage space as oil. The Swedish pellets manufacturers per 1997 are listed. Locally pellets are most conveniently transported as bulk cargo and delivered to a silo by means of pressurized air. Long-distance transport use train or ship. At present, pellets are most often used in large or medium-sized heat plants, but equipment exists for use from private houses and up to the size of MW. Pellets may become the most important alternative to the fossil fuels which along with electricity today are dominating the small scale market. 1 fig., 1 table
