Holistic management – a critical review of Allan Savory’s grazing method

Allan Savory is the man behind holistic grazing and the founder of the Savory Institute. Savory claims that holistic grazing can stop desertification and reduce atmo­spheric carbon dioxide levels to pre-industrial levels in a few decades. In this report, we review the literature on holistic grazing in order to evaluate the scientific support behind these statements

Der er en verden uden for sproget. Om at sikre kvalitet i oversættelse af fagsproglige tekster

Translation of LSP-texts is not merely the transfer of "the meanings of a profession" but also the creation of a new text. Therefore, an important parameter is the neutrality of the translated text: It should observe norms and standards of original texts of a profession, written in the given target language. As many translations show, however, translators often seem not to be acquainted with such norms and standards, a subject which is normally not dealt with in dictionaries. Since a professional world has a restricted professional universe of discourse, being reflected in the - quite stereotype - texts of the profession (which is shown in the present paper with respect to technical texts), it should be possible for the translator trainee to learn what professional texts look like through the study of genuine texts of a profession, getting, at the same time, a certain understanding of the professional world reflected in the texts. It is suggested that, in teaching translation, the focus should at an early stage be put on texts of the target language, as this would secure the familiarity of the translator trainee with genuine structures of the target language before actually beginning the translation of source texts

Quantifying Uncertainties in Mean Absorption Coefficients for a Wall-Stabilized Electric Arc

The quality of arc simulations depends significantly on radiation modeling. Uncertainties due to physical parameters and modeling errors should be systematically quantified. We solve the energy balance equation for a wall-stabilized arc using the P1 model, i.e. without a prescribed temperature profile. We derive the linearized equation and assess the arc voltage sensitivity. This method allows us to optimize the definition of mean absorption coefficients consistently and at low computational costs

A comparison of population types used for QTL mapping in Arabidopsis thaliana

In Arabidopsis, a variety of mapping populations have been used for the detection of quantitative trait loci (QTLs) responsible for natural variation. In this study, we presentan overview of the advantages and disadvantages of the different types of populations used. To do this, we compare the results of both experimental and natural populations for the commonly analysed trait flowering time. It is expected that genome wide association (GWA) mapping will be an increasingly important tool for QTL mapping because of the high allelic richness and mapping resolution in natural populations. In Arabidopsis, GWA mapping becomes ever more facilitated by the increasing availability of re-sequenced genomes of many accessions. However, specifically designed mapping populations such as recombinant inbred lines and near isogenic lines will remain important. The high QTL detection power of such experimental populations can identify spurious GWA associations, and their unique genomic structure is superior for investigating the role of low-frequency alleles. Future QTL studies will therefore benefit from a combined approach of GWA and classical linkage analysis

Modeling potential freshwater ecotoxicity impacts due to pesticide use in biofuel feedstock production - the cases of maize, rapeseed, Salix, soybean, sugarcane and wheat

Ecotoxicity impacts have seldom been included in Life Cycle Assessments of biofuels. This report demonstrates an approach to model the potential freshwater ecotoxicity impacts due to pesticide use, using the PestLCI and USEtox models. The method is applied to eight biofuel feedstock production cases: maize in the US (two cases), rapeseed and wheat in Germany, soybean (two cases) and sugarcane in Brazil, and Salix in Sweden. Potential freshwater ecotoxicity impacts vary by up to 3 orders of magnitude with Salix at the lower end and wheat and rapeseed at the higher end. Potential mitigation strategies include substitution to less toxic pesticides, and reduction of emissions to freshwater ecosystems, through improved management, e.g. the use of buffer zones

Towards an Efficient Arc Simulation Framework

Arc simulations require a coupled solution of the flow and electromagnetic equations. Despite of industrial interest, there is no established simulation framework available yet. We assess the usability of STAR-CCM+ for low voltage circuit breaker simulations using a test case of a model arc chamber, since this toolkit allows to define and control the simulation in a single environment. In spite of a partially implemented arc root model, the results agree well with reference data of previous publications

Characteristics of First-Order Vortex Lattice Melting: Jumps in Entropy and Magnetization

We derive expressions for the jumps in entropy and magnetization characterizing the first-order melting transition of a flux line lattice. In our analysis we account for the temperature dependence of the Landau parameters and make use of the proper shape of the melting line as determined by the relative importance of electromagnetic and Josephson interactions. The results agree well with experiments on anisotropic Y$_1$Ba$_2$Cu$_3$O$_{7-\delta}$ and layered Bi$_2$Sr$_2$Ca$_1$Cu$_2$O$_8$ materials and reaffirm the validity of the London model.Comment: 4 pages. We have restructured the paper to emphasize that in the London scaling regime (appropriate for YBCO) our results are essentially exact. We have also emphasized that a major controversy over the relevance of the London model to describe VL melting has been settled by this wor
