Making market operators responsible for having and giving access to information about their impact on the environment is an important part of changing the way the economy operates in relation to environmental sustainability. To this end, the Norwegian access to environmental information act has established a right for the public to access to environmental information from private entities such as business enterprises. In this point, the Norwegian Act goes further than international rules, such as the Aarhus Convention, and also further than any other national legislation. This article presents the rules on access to information from business enterprises, and presents and discusses examples from the implementation of these rules.

Continuous annular chromatography(CAC) is a separation process for multicomponent liquid mixtures. The performance of the apparatus can be seriously decreased by temperature gradients inside the adsorbent bed. It is shown, that the temperature gradients can be significantly reduced by a pre-heating of the entering liquid in the apparatus itself. Heat transfer and hydrodynamics in the porous media are described by two different modelling approaches. Both are based on a pseudo-homogeneous model for heat transfer with temperature dependent fluid viscosities. The first model considers one-dimensional fluid now and two-dimensional heat transfer. The second, more rigorous one is a three-dimensional model for heat transfer and hydrodynamics. The simulation results obtained with both models are in good agreement with experimental results. The experiments have been performed with glass beads as the stationary phase and water as the liquid phase under different boundary conditions. The temparature profiles inside the packed bed have been measured with thermocouples.

Using 1958-2002 NCEPNCAR reanalysis data, we investigate stationary and transient planetary wave propagation and its role in wave-mean flow interaction which influences the state of the polar vortex （PV） in the stratosphere in Northern Hemisphere （NH） winter. This is done by analyzing the Eliassen-Palm （E-P） flux and its divergence. We find that the stationary and transient waves propagate upward and equatorward in NH winter, with stronger upward propagation of stationary waves from the troposphere to the stratosphere, and stronger equatorward propagation of transient waves from mid-latitudes to the subtropics in the troposphere. stationary waves exhibit more upward propagation in the polar stratosphere during the weak polar vortex regime （WVR） than during the strong polar vortex regime （sVR）. On the other hand, transient waves have more upward propagation during sVR than during WVR in the subpolar stratosphere, with a domain of low frequency waves. With different paths of upward propagation, both stationary and transient waves contribute to the maintenance of the observed stratospheric PV regimes in NH winter.

This paper discusses two core concepts in Hegel’s Phenomenology of spirit: necessity (Notwendigkeit) and memory (Erinnerung). The analysis is based on an investigation of the connotations and linguistic components of the two terms as they are used in the German language. Occurrences of the terms in decisive passages in the Phenomenology of spirit are investigated and seen as a key to an understanding of Hegel’s overall project of constructing a “scientific” (wissenschaftlich) philosophy in the form of a conceptual system. The paper aims at showing that this project can in part be understood as an attempt to transform the contingency of all moments of the path of the self-cultivation, maturation, and growth (Bildung) of spirit (Geist)—understood both in terms of its personal dimension and as “world spirit”—into necessity. It is argued that memory plays a decisive role in this endeavor, not only in the sense of a recalling of the past, but also as a prerequisite for a future that opens up room for further cultivation, maturation, and growth.

The Middle Member of the Zorritas Formation in the Antofagasta region of northern Chile, yielded terrestrial and marine palynomorph assemblages which span the Devonian/Carboniferous boundary. The assemblages show a clear predominance of terrestrial palynomorphs with 70 miospore species, 18 marine phytoplankton species, two non-marine algae and one chitinozoan species, all coming from 15 productive levels. Palynomorphs are poorly preserved and most of them are reworked. Three palyno- logical associations are recognized based on miospores. These are assigned to the Tournaisian-Visean, Tournaisian and probable latest Famennian. Age assignments are discussed in the frame of the spore zonal schemes established for Euramerica and western Gondwana. The stratigraphical distribution of spores allows the identification of the probable position of the Devonian/Carboniferous boundary within the Zorritas Formation. This system boundary is proposed for the first time in Palaeozoic sedimentary rocks of northern Chile. The presence of Gondwanan typical miospore species indicates affinities with this palaeocontinent even though the Tournaisian and Tournaisian-Viseao miospore associations sup- port the cosmopolitanism already suggested for the early Carboniferous flora. The significant number of reworked palynomorphs together with the sedimentological analysis of the studied sections, suggest that these deposits were severely impacted by the climatic change and major sea level fluctuations. similar conditions were recorded in coeval western Gondwana basins.

Background: A central aim of physical education is the promotion of basic motor competencies(in German: Motorische Basiskompetenzen;MOBAK), which are prerequisites for children's active participation in sports culture. This article introduces the MOBAK-1 test instrument for 6-to 8-year-old children and determines the construct validity of this test instrument. In addition, the relationship between MOBAK and motor ability(i.e., strength) as well as body mass index(BMI), sex, and age is ***: We analyzed data of 923 first and second graders(422 girls, 501 boys, age = 6.80 ±0.44 years). The children's basic motor competencies were assessed by the MOBAK-1 test instrument. Besides analyses of frequency, correlation, and variance, 3 confirmatory factor analyses with covariates were ***: We found 2 MOBAK factors consisting of 4 items each. The first factor, locomotion, included the items balancing, rolling, jumping, and side stepping; the second factor, object control, included the items throwing, catching, bouncing, and dribbling. The motor ability strength had a significant influence on the factors locomotion(b = 0.60) and object control(b = 0.50). Older pupils achieved better results than younger pupils on object control(b = 0.29). Boys performed better on object control(b = -0.44), whereas girls achieved better results in locomotion(b = 0.07).Pupils with a high BMI achieved lower performance only on the factor locomotion(b =-0.28).Conclusion: The MOBAK-1 test instrument developed for this study meets psychometric validity demands and is suitable to evaluate effects of sports and physical education.

Models of hierarchical galaxy formation predict that the extended stellar halos of galaxies like our Milky Way show a great deal of sub-structure, arising from disrupted satellites. spatial sub-structure is directly observed, and has been quantified, in the Milky Way＇s stellar halo. Phase-space conservation implies that there should be sub-structure in position-velocity space. Here, we aim to quantify such position-velocity sub-structure, using a state-of-the art data set having over 2000 blue horizontal branch （BHB） stars with photometry and spectroscopy from sDss. For stars in dynamically cold streams （＂young＂ streams）, we expect that pairs of objects that are physically close also have similar velocities. Therefore, we apply the well-established ＂pairwise velocity difference＂（PVD） statistic （｜ △Vlos ｜）（△r）, where we expect （｜ △Vlos ｜） to drop for small separations At. We calculate the PVD for the sDss BHB sample and find 〈｜ △Vlos ｜〉（△r） ≈ const., i.e. no such signal. By making mock-observations of the simulations by Bullock ＆ Johnston and applying the same statistic, we show that for individual, dynamically young streams, or assemblages of such streams, （｜ △Vlos ｜） drops for small distance separations At, as qualitatively expected. However, for a realistic complete set of halo streams, the pair-wise velocity difference shows no signal, as the simulated halos are dominated by ＂dynamically old＂ phase-mixed streams. Our findings imply that the sparse sampling and the sample sizes in sDss DR6 are still insufficient to use the position-velocity sub-structure for a stringent quantitative data-model comparison. Therefore, alternate statistics must be explored and much more densely sampled surveys, dedicated to the structure of the Milky Way, such as LAMOsT, are needed.
