It is also known as a tolerogenic microenvironment. Here, we demonstrate that immune responses in the vagina are orchestrated by the functional diversity of four major antigen-presenting cell (APC) subsets. Langerhans cells (LCs) and CD14 − lamina propria (LP)-DCs polarize CD4 + and CD8 + T cells toward Th2, whereas CD14 + LP-DCs and macrophages polarize CD4 + T cells toward Th1. Both LCs and CD14 − LP-DCs are potent inducers of Th22. Due to their functional specialties and the different expression levels of pattern-recognition receptors on the APC subsets, microbial products do not bias them to elicit common types of immune responses (Th1 or Th2). To evoke desired types of adaptive immune responses in the human vagina, antigens may need to be targeted to proper APC subsets with right adjuvants.

The power spectrum S(q,t) presents a clear q-γ dependence in the region of high frequencies and the interface width of the films follows a tβ behavior. The values obtained for the two exponents (γ=4.1 and β=0.26) agree with the theoretical predictions (γ=4 and β=0.25) for a process controlled by pure surface diffusion in the thickness range studied. The power spectrum at high frequencies is similar for different film thickness describing a phenomenon free from anomalous scaling. We also conclude that dimensional analysis of profiles presents some practical problems in its application. On the other hand, frequency analysis of the whole image allows us to obtain a reliable determination of surface roughness.

The potential for determining the structures of biomolecules and their complexes emphasizes the relevance of developing procedures for STM image enhancement. Some software procedures have focused attention on the correction of geometrical distortion arising in STM images. It is ...

The programs that nowadays try to take advantage of these new technologies, cannot be written using the traditional techniques of programming, since most of the algorithms were designed for being executed in only one processor, in a nonconcurrent form, instead of being executed concurrently in a set of processors, working and communicating through a network. This work aims to present the ongoing development of a new method to simulate the Ferromagnetic Potts model, taking into account these new technologies.

This kind of evaluation is of importance in Co-based alloys because the surface roughness is related to magnetic properties in low and medium magnetostriction. This paper presents a study of the surface roughness of Co-based alloys obtaining the fractal dimensionality, the amplitude of the superficial features as well as the mean size of those features and its relation to magnetic properties. 0304-3991/92/$05.00

The main surface texture parameters (such as the r.m.s. roughness, kurtosis, skewness, and average wavelength) show a strong dependence on the conditions used in the feedback loop for imaging. Fractal character changes also with feedback parameters. The quality of the STM images can be measured quantitatively by using some of the surface texture parameters.

The power spectrum S(q, t) presents a clear q−c dependence in the high-frequency region and tb behaviour of the total interface width of the films. The values obtained for the two exponents, in the range of 300-18 000 Å thickness studied (c=4.1±0.1 and b=0.26±0.02), agree with the theoretical predictions (c=4 and b=0.25) for a pure diffusion-controlled process but not with a re-evaporation process. The power spectrum for high frequencies shows good correlation for different film thicknesses, describing scaling without anomalous behaviour.
