The objectives of this study were to determine the effect of using corn stover or three different wood-based bedding materials (kiln-dried pine wood chips, dry cedar chips, or green cedar chips) on airborne concentrations of NH, total reduced sulfides (TRS), CO, CH, and NO above lab-scaled bedded manure packs. Four bedded packs of each bedding material were maintained for two 42-d periods. Airb...

The thalamus is a central element for the generation of rhythmic oscillatory activity under physiological and pathophysiological conditions. Especially slow oscillations in the delta and theta frequency band which normally occur during slow-wave sleep are associated with a number of neuropsychiatric conditions if they occur during wakefulness and may be the basis for the generation of character...

In the context of nuclear waste disposal in clay formations, laboratory experiments were performed to study at reduced scale the Excavation Damaged Zone (EDZ) induced by the construction of galleries in the Boom Clay formation. For this purpose, thick-walled hollow cylindrical samples were subjected (after recovery of in-situ stress conditions) to a decrease of the inner confining pressure aimi...

The purpose of this study was to determine the effect of 2 different bedding types, sand and wood shavings, on the behavior of broiler chickens. In experiment 1, 6 pens were divided down the center and bedded half with sand and half with wood shavings. Male broilers (10/pen) were observed by scan sampling at 5- or 12-min intervals throughout the 6-wk growth period during the morning (between 08...

Abstract Sedimentological and geochemical records are presented for an upper Paleocene to middle Eocene deep-water pelagic succession of the Pabdeh Formation in Paryab section, Zagros Mountains, NW, Iran. In this study, grain-size statistical parameters, cumulative curves, bivariate analysis on twenty-five sediment samples were used decipher depositional processes paleoenvironments. XRD fine-gr...

PURPOSE This systematic review was conducted to gain insight into the efficacy of transmission of infectious agents to colony sentinels by soiled bedding transfer based on publications studying this subject in mice and rats. This information is essential to establish recommendations for the design of health monitoring programs which use sentinels to determine the microbiological status of labor...

Broiler chicken production is widely dispersed across the globe, and one important issue for growers is the selection of adequate bedding material, as the availability and price of substrates varies among countries and regions within a same country. This study aimed at applying a multiple criteria analysis approach for the selection of the most appropriate bedding material for broiler productio...

This experiment compared the effects of sand and straw bedding in free stalls on resting time, cleanliness, hock injuries, and hoof health of dairy cows and tested whether cow preferences for a bedding material depended on the familiarity with the material. A total of 52 dairy cows were kept either on straw bedded concrete stalls or sand stalls for at least 21 wk. The lying behavior was observe...

[1] Thermal conductivity anisotropy was determined for three sets of metasedimentary and igneous rocks from central Utah, USA. Most conductivity measurements were made in transient mode with a half-space, line source instrument oriented in two orthogonal directions on a flat face cut perpendicular to bedding. One orientation of the probe yields thermal conductivity parallel to bedding (kpar) di...

We used a high-density array of real-time PCR assays for commonly reported rodent infectious agents (PRIA) to test naturally infected index mice and sentinel mice exposed by contact and soiled-bedding transfer. PRIA detected 14 pathogens--including viruses, bacteria, fur mites, pinworms, and enteric protozoa--in 97.2% of 28 pooled fecal samples, fur-perianal swabs, and oral swabs from 4 cages c...
