Macropores and water flow in soils and substrates are complex and are related to topics like preferential flow, nonequilibrium flow, and dual-continuum. Hence, the quantification of the number of macropores and the determination of their geometry are expected to provide a better understanding on the effects of pores on the soil's physical and hydraulic properties. This exploratory study aimed a...

The present paper investigates consequence relations that are both paraconsistent and plausible (generally nonmonotonic too). More precisely, we lay the focus on preferential consequence relations, i.e. those relations that can be defined by a binary preference relation on states labelled by valuations (such as in Non-monotonic Reasoning). The first purpose of the paper is to provide characteri...

Two series of displacement experiments with isoproturon and metribuzin herbicides were performed on two undisturbed grassed filter strip soil cores, under unsaturated steady-state flow conditions. Several rainfall intensities (0.070, 0.147, 0.161, 0.308 and 0.326 cm h(-1)) were used. A water tracer (bromide) was simultaneously injected in each displacement experiment. A descriptive analysis of ...

Intrarenal blood flow distribution was measured by the '33xenon washout technic in 10 patients with heart disease who were studied at time of left and right heart catheterization. Renal washout curves were analyzed by computer using a weighted least-squares nonlinear regression technic. In three patients with heart disease without edema the compartment I blood flow rates (outer cortex) were not...

Abstract. Some observations concerning the structure of turbulence associated with an exothermic nonpremixed reacting flow are presented. Direct numerical simulations (DNS) with a resolution of 1283 grid points and an initial Reynolds number R~ = 33 provide data for the analysis. In these simulations the density varies with temperature and the resulting flow field is inhomogeneous. Conditional ...

A novel mechanism for the generation and amplification of intrinsic rotation at the low-mode to high-mode transition is presented. The mechanism is one where the net parallel flow is accelerated by turbulence. A preferential direction of acceleration results from the breaking of k →−k symmetry by sheared E B flow. It is shown that the equilibrium pressure gradient contributes a piece of the par...

In this paper we propose a propositional temporal language based on fuzzy temporal constraints which turns out to be expressive enough for domains –like many coming from medicine– where knowledge is of propositional nature and an explicit handling of time, imprecision and uncertainty are required. The language is provided with a natural possibilistic semantics to account for the uncertainty iss...

Entailment that is based on the application of simple production rules, of the form c← a1, . . . , an (n ≥ 0) is weaker than the propositional entailment that would be yielded by translating these rules into material implications. In this paper, we show that rulebased entailment coincides with the propositional entailment of literals, when the set of rules is closed under transposition, transit...

Research in abstract argumentation typically pertains to finite argumentation frameworks (AFs). Actual or potential infinite AFs frequently occur if they are used for the purpose of nonmonotonic entailment, so-called instantiation-based argumentation, or if they are involved as modeling tool for dialogues, n-person-games or action sequences. Apart from these practical cases a profound analysis ...
