Analysis of small-scale movement patterns of animals we may help to understand and predict movement at a larger scale, such as dispersal, which is a key parameter in spatial population dynamics. We have chosen to study the movement of a soil-dwelling Collembola, Protaphorura armata, in an experimental system consisting of a clay surface with or without physical obstacles. A combination of video re

One way to extend the lean-burn limit of a natural gas engine is by addition of hydrogen to the primary fuel. This paper presents measurements made on a one-cylinder, 1.6- liter natural gas engine. Two combustion chambers, one slow and one fast burning, were tested with various amounts of hydrogen (0, 5, 10 and 15%-vol) added to natural gas. Three operating points were investigated for each combus

The influence of the shear on the lamellar phase, L, of the system C10E3/D2O was studied along an isoplethal path (40 wt.% C10E3) in the temperature range 25-42degreesC. A dynamic phase diagram was determined by steady-state rheometry, where by shear action the lamellar phase was transformed into multilamellar vesicles (MLVs) ("onions"). The location of "onions" in the dynamic phase diagram, depen

Let H be a Hilbert space of analytic functions on the open unit disc D such that the operator M. of multiplication with the identity function. defines a contraction operator. In terms of the reproducing kernel for H we will characterize the largest set Delta(H) subset of partial derivative D such that for each f, g is an element of H, g not equal 0 the meromorphic function f/g has nontangential li

Theory is presented that extends the analysis to signal correlation between any antennas in an array of elements. It is generalised to include non-identical elements and arbitrary load termination of passive antenna ports. The method is related to the power balance concept and based on the antenna impedance matrix.

Objective: Interstitial laser coagulation (ILC) of the prostate is a minimally invasive method for treating symptomatic benign prostatic enlargement (BPE). We performed a prospective randomized study to compare the clinical outcomes of ILC and transurethral resection of the prostate (TURP). Material and Methods: Between December 1997 and February 2000, 38 patients with moderate-to-severe symptomat

We have designed and synthesized a new series of azapeptides which act as potential inhibitors of cathepsin B and/or cathepsin K. Their structures are based upon the inhibitory sites of natural cysteine protease inhibitors, cystatins. For the synthesized azapeptides, the equilibrium constants for dissociation of inhibitor-enzyme complex, K-i, were determined. Comparison of these values indicated t

Popular Abstract in Swedish Torkning av ett poröst material sker i två perioder: en period med konstant torkhastighet och en period med fallande torkhastighet. Under perioden med konstant torkhastighet, bestäms torkhastigheten av de yttre förhållandena beträffande värme- och masstransport, och torkhastigheten påverkas inte av det torkande materialets egenskaper. Under perioden med fallande torkhasThe drying of a porous material occurs in two different periods: the constant rate period and the falling rate period. During the constant rate period, the drying rate is determined by the external conditions regarding heat and mass transfer, and the drying rate is not influenced by the properties of the drying material. During the falling rate period, the material properties, such as the transpor

Peptidoglycan from Staphylococcus aureus mobilized CD66b in human neutrophils but did not upregulate surface activation markers in eosinophils. In addition, Toll-like receptor 2, implicated in the recognition of peptidoglycan, was detected on the surface of resting neutrophils but not on eosinophils. These findings suggest roles for neutrophils but not eosinophils in innate recognition of peptidog

The story of the International Industrial Relations Institute (IRI), its de facto leader Mary van Kleeck from the United States and its first chairman Kerstin Hesselgren from Sweden begins in 1925, when the IRI was established at a congress for welfare and personnel workers in Holland. At first the organization was focused on scientific management and industrial relations but during the Great Depr

The inverse scattering problem on the half-axis is solved for scattering matrices which result from scattering on a zero-range potential with an internal structure. The solutions are constructed as pointwise limits of Bargmann potentials and form a one-parameter family, We obtain a class of potentials decreasing slowly at infinity.

In male birds, testosterone (T) plays an important role in aggressive and mate-attraction behaviour. In the cooperatively breeding Seychelles warbler, Acrocephalus sechellensis, extra-group copulations (EGCs) occur frequently, but are not accompanied by sexual courtship displays as in within-pair copulations. Paternity is nearly always gained by primary males. We investigated whether T levels and
