A suite of analytical techniques was used to obtain a comprehensive picture per- and polyfluoroalkyl substances (PFAS) in selected Canadian food packaging for fast foods (n = 42). Particle-induced gamma ray emission spectroscopy revealed that 55% the samples contained <3580, 19% 3580–10 800, 26% > 10 800 ?g F/m2. The highest total F (1 010 000–1 300 000 F/m2) measured molded “compostable” bowls...

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...

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...

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 ...

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...

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 ...

Exposure to organic solvent vapors was investigated in 40 unit workplaces (with 189 workers) in 16 small-scale industries in north-east Japan (Tohoku District) in which synthetic urushi lacquer was applied to produce non-metal tableware (e.g. soup bowls, rice bowls), flower vases, home altars, etc. Two furniture factories were also studied. The equipment used was carbon felt dosimeters and a po...

A series of buckybowls with different sizes and structures have been tested as potential receptors of fullerenes C60, C70 and C40. Among these bowls are corannulene (C20H10), sumanene (C21H12), pinakene (C28H14), hemifullerene (C30H12), circumtrindene (C36H12), pentaindenocorannulene (C50H20) and bowl-shaped hexabenzocoronene derivatives. An exhaustive study, taking into account different orien...

The bowl-championship-series (BCS) committee uses 10 ranking schemes, including eight computer rankings, to select college football teams for bowl-championship-series bowl games, including the national championship game. The large financial benefits of participating in BCS bowl games make it imperative that the selection process accurately select the best teams. I evaluated the performance of t...
