Dissymmetric warfare versus asymmetric warfare

This paper presents two concepts: asymmetric warfare and dissymmetric warfare. NATO and US Military operations in recent wars in Kosovo and Afghanistan are analysed by means of comparison with old Chinese strategic thinking. No‐Loss‐Strategy and virtual warfare as well as the transformation from asymmetric to dissymmetric and from dissymmetric to asymmetric warfare are reflected upon.

Welfare issues of donkey (Equus asinus): a checklist based on the five freedoms

Studies on the welfare of donkey (Equus asinus) have developed slowly, because considered very rustic animals, reared prevalently under extensive production systems and widespread mainly in marginal areas. The diffusion of extensive breeding of this species has led to the belief that donkey did not need any welfare assessment. More recently, the scenario has changed, due to a gradual diffusion of intensive and semi-intensive production systems, especially in highly productive dairy breeds, to the growing concern of consumers about the life conditions of farmed animals, and to the issuing of a number of national and European rules / laws on the safety of animal products and well-being of farmed livestock. Relating with the importance of this species on food farming industry, the Author underlines the missing of specific recommendations concerning the welfare of farmed donkey. In absence of common criteria and guidelines, it is possible to make reference to the well-known “five freedoms”. This paper will review the main welfare issues of donkeys and the following aspects will be considered: nutrition, housing and management, clinical problems, behaviour problems.     

Zur numerischen Pumpversuchsauswertung in Mehrschichtgrundwasserleitern

The analysis of well tests conducted in complex geological units is often not well suited with classical analytical approaches. Numerical simulators are usually needed to account for unconventional test conditions in order to analyze data which do not fit within analytical theory. In the current work, a numerical method for simulating pumping tests is adopted, which was developed about 30 years ago in the UK. The method is expanded within the present work to allow for a consistent analysis of pumping tests, vertical interference tests, pressure pulse tests, drillstem tests, and slug tests. Two-layer formations and their dual permeability equivalents can be treated by the implemented model including nonlinear well entrance losses. The application of the model is demonstrated for a pumping test conducted in the Oligocene base formation at the Teltow-Plateau south of Berlin. The test aimed at investigating potential leakages between this poor water quality base formation and overlying high water quality aquifers envisioned for future drinking water exploitation.
