This study compared proportion of animals with shoulder and vulvar lesions and scores for cleanliness, body condition, and lameness in sows housed in four different group-housing facilities. Inspectors visited each herd once per month and scored sows for each parameter. All farms housed gestating sows in groups, but pen designs and management differed on each farm. Differences among herds were ...

This study was designed to examine the characteristics of sawdust and cocopeat bedding materials, including physicochemical properties (Exp. I) and on-farm trial (Exp. II). In Exp. I, the proportion of particle size was in the order of sawdust> cocopeat India>cocopeat Vietnam (p<0.05), and cocopeat contained higher proportion of small particles (250 μm+below 250 μm) than sawdust, causing a dust...

Introduction During the summer and fall of 1997, the Hoop Research Complex was developed at the Iowa State University (ISU) Rhodes Research Farm for comparing hoop structures to confinement for swine finishing. The site consists of three hoop structures and one modular confinement building. The hoops, each 30 ft × 60 ft, are oriented north/south. The south end of each hoop has a concrete floor ...

The speed and pen-pressure while sketching a spiral are lower among Parkinson's disease (PD) patients with higher severity of the disease. However, the correlation between these features and the severity level (SL) of PD has been reported to be 0.4. There is a need for identifying parameters with a stronger correlation for considering this for accurate diagnosis of the disease. This study has p...

We explore how pen-based mobile devices may be used for mathematics instruction. It is convenient to split the function of a math e-Learning system between these light-weight devices and a server running a content management system. Functions such as sketching and entering and displaying mathematical expressions can be performed on the mobile devices, while other functions such as computing plo...

There are many similarities between prototyping for traditional computer games and prototyping for other interactive systems, for example, applications for the work place. In most cases, pen and paper are used to initially test design ideas and feasibility. However, in audio games pen and paper can be rather useless for sketching the user experience of sound. In this paper, we argue that conven...

A study of papers on amyloid fibers suggested to us that cylindrical beta-sheets are the only structures consistent with some of the x-ray and electron microscope data. We then found that our own 7-year-old and hitherto enigmatic x-ray diagram of poly-L-glutamine fits a cylindrical sheet of 31 A diameter made of beta-strands with 20 residues per helical turn. Successive turns are linked by hydr...

Spontaneous autoinflation of saline-filled breast implants is a rare phenomenon; only 20 cases have been reported in the world literature. Over the past seven years, three patients have presented with significant unilateral autoinflation of their smooth, single-lumen, round, saline-filled implants. This developed at various times: progressively over 23 years with a Simaplast implant; between th...
