A popular retrofit option is to install an exterior insulation finish system to the walls of existing buildings. This study evaluates the thermal and moisture performance of such a system with a vented wall assembly. In addition to being a case study, this field monitoring was intended to verify computation methods of building envelope performance. The long term monitoring was designed to be no...

Films are thin coatings of materials that protect the product against mechanical and corruption factors. The use of edible films and coatingsis developed these days because they can retain the quality, flavor and moisture content of the product and also are degradable and easy to use. Proteins are an apt choice for such film’s base material as their suitable barrier property against oxygen, CO2...

The backfill materials around under-ground power cables affect the maximum current carrying capacity of these cables. Usually backfill soils around under-ground power cables lose their moisture content, forming dry zones around the cables and leading to an increase in the thermal resistance and decreasing in maximum current carrying capacity. But according to the results of the experimental wor...

A new device for stopping or reducing potentially irritating or harmful emissions from surfaces indoors is described. The device is a surface emissions trap prototype and consists of an adsorbent sheet with a semipermeable barrier surrounded by two thin nonwoven layers. The trap may be applied directly at the source of the emissions e.g. at moisture-affected floors and walls, surfaces contamina...

As a white pigment, titanium oxide is used for cosmetic application. This oxide is well known to have the photo catalytic activity. Therefore a certain degree of sebum is decomposed by the ultraviolet radiation in sunlight. In this work, titanium phosphates were prepared with additives (urea, sodium lactate, and glycerin) as a novel white pigment. Their chemical composition, powder properties, ...

T he demands of the automotive industry on components are increasing continuously and thus time and again raise new challenges for the materials used. That means that plugs, plug connectors and housings for electronic components (Title picture) as well as overmolded sensors for under the hood applications which are often made from polybutylene terephthalate (PBT) have to pass even harder tests....

This paper presents fabrication of RFID tags, especially antennas for HF band (13.56 MHz), on cheap flexible substrates. The physicochemical, geometrical, DC and AC electrical properties as well as long-term stability (under thermal, moisture-thermal and mechanical exposures) have been characterized for several low-temperature polymer thick-film conductive films made on various paper or foil su...

Precision components or sensors exposed to corrosive conditions, or required to have extreme performance characteristics, are sealed hermetically into special packages. Epoxy glueing, resistance welding, soldering, electron-beam welding, and laser welding are several of the techniques available for sealing these packages. The disadvantage in the use of epoxies is that they do not create a herme...

Thermal inactivation of desiccation-adapted Salmonella spp. in aged chicken litter was investigated in comparison with that in a nonadapted control to examine potential cross-tolerance of desiccation-adapted cells to heat treatment. A mixture of four Salmonella serovars was inoculated into the finished compost with 20, 30, 40, and 50% moisture contents for a 24-h desiccation adaptation. Afterwa...

Habitat distribution and seasonal occurrence of carabid beetles were determined using pitfall traps in 1999 and 2000 in the temperate forest zone of the Dongling Mountain, North China. Eight sites differing in vegetation and moisture were selected so as to represent four habitat types. Carabid assemblages of the six forested habitats (lowland, upland and coppice) were more similar to each other...
