The article presents diagnostic possibilities for testing covering of roadway through dynamic and static loading units. features, advantages principal characteristics the equipment: die unit, Dina-3M, UDN-NK, Dynatest unit. main parameters impact also results tests by loading, defines «flexural bowls», elastic module coefficients reduction modulus to modulus.

Colloidal particles with two or more different surface properties (Janus particles) are of interest in catalysis, biological imaging, and drug delivery. Eccentric nanoparticles are a type of Janus particle consisting of a shell that envelops the majority of a core particle, leaving a portion of the core surface exposed. Previous work to synthesize eccentric nanoparticles from silica and polysty...

Among the many ways that music affects the human spirit, personal growth and healing are among the newest and the oldest. It was not until World War II that a modern society accepted music as a source of healing. During that era, musicians were hired to perform for injured soldiers in hospitals. This paper describes how the uses of a type of friction idiophone, popularly known as singing bowls ...

The following is a modification of the first four sections of a paper with the same title published in the Anais da Academia Brasileira de Ciencias (volume 36, 245-259 (1964)), referred to herein as M [O]. The aim is to clarify the hypotheses of the original paper. The principal results are Theorems 4.1 and 4.2. Proofs of these theorems are found in §§5-10 of M [0]. Parts II and III are in M [O...

On February 29, 2004, the college football Bowl Championship Series (BCS) announced a proposal to add a fifth game to the “BCS bowls” to improve access for mid-major teams ordinarily denied invitations to these lucrative postseason games. Although still subject to final approval, this agreement is expected to be instituted with the new BCS contract just prior to the 2006 season. There aren’t to...

The mechanism for the diffusion of vinyl bromide (VB) through the nonporous van der Waals organic solid of p-tert-butylcalix[4]arene (tBC) is examined by molecular mechanics calculations. In a "squeeze" mechanism, a VB molecule passes through the interstitial space in the rim regions of tBC bowls, after the partial filling of nearby inclusion sites, and couples with the both the rotation of but...

If rodents do not display the behavioral complexity that is subserved in primates by prefrontal cortex, then evolution of prefrontal cortex in the rat should be doubted. Primate prefrontal cortex has been shown to mediate shifts in attention between perceptual dimensions of complex stimuli. This study examined the possibility that medial frontal cortex of the rat is involved in the shifting of ...

Stress experienced in childhood is associated with an increased risk of developing psychiatric disorders in adulthood. These disorders are particularly characterized by disturbances to emotional and cognitive processes, which are not currently fully modeled in animals. Assays of cognitive bias have recently been used with animals to give an indication of their emotional/cognitive state. We used...

During the first few days after weaning, pigs often experience BW loss as they adapt to eating solid food. During this time period, they are also known to drink excessively and develop abnormal oral behavior such as belly nosing. The excessive drinking may stem from the piglets' attempt to satiate hunger through gut fill from a familiar ingestive source. Gut fill through water intake may affect...
