Abstract:
Die Genauigkeit und Eignung verschiedener Methoden zur Humusbilanzierung werden für den Einsatz in der konventionellen und ökologischen Landwirtschaft ausgewertet. Weiterhin wurde das Versorgungsniveau mit organischer Substanz auf den Dauertestflächen sächsischer Betriebe beurteilt. Anhand der genaueren, standortangepassten Methode zur Humusbilanzierung zeigt sich, dass in Sachsen die Hälfte der Ackerflächen mit organischer Substanz optimal versorgt ist. Knapp ein Drittel der Schläge erhält eine hohe bis sehr hohe Versorgung, der Anteil unterversorgter Flächen liegt bei 20 Prozent.

Abstract:
Den moderna filosofiska analysen av kausalitet utarbetades under 1700-talet av den skotskefilosofen David Hume. Under beteckningen regularitetsteorin har Humes analys varit utgångspunkten för alla senare empiriska analyser av orsaksförhållanden. Men Humes ståndpunkt om kausalitet tolkas olika och åsikterna varierar om vad hans orsaksteori utgörs av. En samtida tolkning av Hume som kausal realist gör gällande att Hume tror på existensen av objekt i tid och rum som är oberoende av våra sinnen och som uttrycker kausala relationer, vilka upprätthålls av icke–reducerbara kausala krafter.

The importance of humus form or forest floor as a principal component of terrestrial forest ecosystems has led to the development of a taxonomic classification of humus forms for BC (first approximation: Klinka et al. 1981; second approximation: Green et al. 1993). This classification, as all others, is based on the field-observable (morphological) features because we expect that they reflect differences in the nature and development of humus forms. However, there is a continuing need to test (1) whether humus forms that appear different are in fact different in their physical, chemical, a

Regime recognition is an important tool used in creation of usage spectra and fatigue loads analysis. While a variety of regime recognition algorithms have been developed and deployed to date, verification and validation (V&V) of such algorithms is still a labor intensive process that is largely subjective. The current V&V process for regime recognition codes involves a comparison of scripted flight test data to regime recognition algorithm outputs. This is problematic because scripted flight test data is expensive to obtain, may not accurately match the maneuver script, and is often used t

Abstract:
<p>The effect of humps on the stability of subsonic boundary layers over an airfoil is investigated. The mean flow is calculated by using an interacting boundary-layer solver which accounts for strong viscous/inviscid interaction and separation bubbles. The code is capable of solving compressible as well as incompressible flows. Then, the two-dimensional mean flow is fed into a stability program which is capable of doing two-and three-dimensional analysis. The output of this stability program is the growth rates which are integrated along a prescribed path to yield the amplification factor (i.

Abstract:
Dans le cadre de l'optimisation de la fiabilité, Thales Optronique intègre désormais dans ses équipements, des systèmes d'observation de leur état de fonctionnement. Cette fonction est réalisée par des HUMS (Health & Usage Monitoring System). L'objectif de cette thèse est de mettre en place dans le HUMS, un programme capable d'évaluer l'état du système, de détecter les dérives de fonctionnement, d'optimiser les opérations de maintenance et d'évaluer les risques d'échec d'une mission, en combinant les procédés de traitement des données opérationnelles (collectées sur chaque appareil grâce au HU

Abstract:
Vor dem Hintergrund der steigenden CO2-Konzentration in der Atmosphäre gewinnt die Rolle des Waldes als C-Speicher zunehmend an Bedeutung. Eine besonders wichtige Funktion kommt hierbei dem Boden zu, denn Böden speichern weltweit mehr C als Vegetation und boden zusammen (Brady and Weil, 2002). Im Sinne einer nachhaltigen Waldbewirtschaftung werden in Sachsen derzeit großflächig die bestehenden Nadelforsten in naturnahe, strukturierte Laub- und Laubmischwälder umgewandelt. Ziel dieser Arbeit war es daher, baumarten- und bewirtschaftungsspezifische Effekte auf den Humus und die C-Speicherung im

Abstract:
En el presente trabajo se muestran los resultados de una serie de pruebas pirometalúrgicas que se han realizado en un horno rotativo cilíndrico de sección corta, que es el más indicado para la fusión de polvos aglomerados, y apropiado por dar una buena distribución del calor durante la fusión. Se debe recalcar en este trabajo que el Complejo Metalúrgico de La Oroya es un conjunto de plantas que están diseñadas para tratar concentrados de diferentes minerales con altos niveles de contaminantes, obteniendo así rentabilidad en los subproductos que recupera, tales como la plata, antimonio, cadmio
