UNLABELLED   Background. Foam and gauze are two types of wound fillers used for negative pressure wound therapy (NPWT). Differences in the wound healing effects of foam and gauze have been observed clinically. The aim of the present study was to examine the effects of NPWT on the wound bed using foam and gauze. METHODS A porcine peripheral wound model was treated with NPWT at 0, -75 mmHg, o...

The purpose of our study was to investigate the expression levels of TREM-1 (triggering receptor expressed on myeloid cells-1) in U937 foam cells and determine whether TREM-1 regulates the production of tumor necrosis factor-alpha and interleukin-8 in these cells. Human U937 cells were incubated with phorbol 12-myristate 13-acetate and then oxidized human low-density lipoprotein to induce foam ...

1.1 What is CNT foam? Foam is a macroporous material and comes in many forms, such as polystyrene shock absorbers, dish-washing sponges, and foam board insulation. This chapter describes a technique to prepare foam materials from carbon nanotubes (CNTs). The use of a CNTmade foam as a kitchen sponge may not be a good idea, however. We of course expect the nano-carbons to have a specific functio...

The effect of the foam covered ocean surface on the passive microwave remote sensing measurements is studied based on the electromagnetic scattering theory. In fomulating an electromagnetic scattering model, we treat the foam as densely packed sticky air bubbles coated with thin seawater coating. The layer of foam covers the ocean surface that has air bubbles. We then use dense media radiative ...

The paper is concerned with the boundary controllability of entropy weak solutions to hyperbolic systems of conservation laws. We prove a general result on the asymptotic stabilization of a system near a constant state. On the other hand, we give an example showing that exact controllability in finite time cannot be achieved, in general.

By using concrete scenarios, we present and discuss a new concept of probabilistic Self-Stabilization in Distributed Systems.

Dijkstra’s concept of self-stabilization assumes that faults can only affect the variables of a program. We study the notion of self-stabilization if faults can also affect (i.e., augment) the program code of a system. A code stabilizing system automatically recovers from (almost) arbitrary perturbations of its program code. We prove some lower bounds for code stabilizing systems and argue that...

The purpose of this study was to investigate the acute effects of foam rolling on quadriceps isokinetic and isometric force production as well as knee joint range of motion. Twelve healthy, light to moderately physically active college students volunteered for this study. They had different treatments on three separate days. Participants' non-dominant knee joint range of motion (ROM), quadricep...
