With the development of new cement-based raw materials, foaming agents and fillers used for special applications foam concrete, use concretes has become widespread. Foam concrete is a type that stands out with its lightness, waste potential, controlled low strength, thermal insulation, acoustics performance, durability. The knowledge base still developing this particular building material. This...

A new flexible thermal insulation sheet, a composite of silica aerogel with polypropylene (PP) foam, has been developed. Even though large volume ratio (97%) was included, the showed high flexibility. Thermal conductivity 0.016 W/(m?K) at 298 K, which is as low monolith. Silica flaking, problem in practical applications, very this due to skin layers polymer-foam composite. supercritical drying ...

Moisture distribution information is a critical element in drying processes. The of products by employing high-power microwave (MW) technology widely used the industry. Although microwaves allow volumetric and selective heating resulting significant reduction processing time energy consumption, there always risk non-uniform moisture final product. This paper investigates capability designed ele...

INTRODUCTION There is evidence that increased ambient pressure causes an increase in postural sway. This article documents postural sway at pressures not previously studied and discusses possible mechanisms. METHODS Eight subjects participated in a dry chamber dive to 240 msw (2.5 MPa) saturation pressure. Two subjects were excluded due to unilateral caloric weakness before the dive. Postural...
