In this paper we discuss inverse problems in infiltration. We propose an efficient method for identification of model parameters, e.g., soil parameters for unsaturated porous media. Our concept is strongly based on the finite speed of propagation of the wetness front during the infiltration into a dry region. We determine the unknown parameters from the corresponding ODE system arising from the...

When grown on a soft agar surface in a rich medium, cells of Salmonella typhimurium elongate, produce extra flagella and move over the surface in a coordinated manner. In mutants with defects in the chemotaxis signaling pathway, the agar plates remain dry and the cells' flagella are short. Recent work shows that the anti-sigma factor controlling late-gene flagellar synthesis is secreted less by...

Methods Efficacy studies were conducted according to ASTM E1174 or with modifications to the hand contamination procedure as follows: For ASTM E2755 studies, hands were contaminated with 0.2 ml of a concentrated challenge suspension to reduce soil load and eliminate post contamination hand wetness commonly associated with testing per E1174. For the “contact contamination” procedure hands were c...

Dhat syndrome is a commonly diagnosed disorder in Indian male patients. Patients present with various physical and mental symptoms which are attributed to the passage of "Dhat"(commonly semen) in urine. A case of an adult female is described who presented with complaints of aches and pains, headaches and poor concentration which she attributed to "wetness" experienced per vaginum during sexual ...

2) Section 1, line 84: “in the study the relationship of the temporal and spatial variation of soil moisture is determined by establishing its controlling factors . . .” The sentence is revised as “in this study the relationship between variation of soil moisture and its controlling factors (e.g. topography and precipitation) is established.” That mean the modified wetness index. Line 110: “. ....
