−− The falling cylinder viscometer (FCV) is a reliable instrument to quantify the viscosity of Newtonian fluids. Nevertheless, when nonNewtonian fluids are tested in this device, difficulties appear to determine the apparent viscosity. Thus, conventional rheometric calculations cannot be applied directly to experimental data provided by the FCV in order to obtain the apparent viscosity function...

Clinical signs of upper respiratory tract infection can be hard to manage in cats, particularly those in shelters. In this study, clinical data were collected from chronically ill (3-4 weeks' duration) cats with suspected feline herpesvirus-1 (FHV-1) or feline calicivirus (FCV) infections after administration of one of two novel therapies. Group A cats were administered a commercially available...

Forty-two seronegative cats received an initial vaccination at 8 weeks of age and a booster vaccination at 12 weeks. All cats were kept in strict isolation for 3 years after the second vaccination and then were challenged with feline calicivirus (FCV) or sequentially challenged with feline rhinotracheitis virus (FRV) followed by feline panleukopenia virus (FPV). For each viral challenge, a sepa...

Over the last several decades, hydrogen fuel cell vehicles (FCVs) have emerged as a zero tailpipe-emission alternative to the battery electric vehicle (EV). To address questions about consumer reaction to FCVs, this report presents the results of a “ride-and-drive” clinic series (n=182) held in 2007 with a Mercedes-Benz A-Class “F-Cell” hydrogen FCV. The clinic evaluated participant reactions t...

A common part of the documentation of archaeological finds is the drawing of so-called rollouts. Rollouts provide a complete and continuous depiction of graphical elements on the surface of rotation-symmetric objects and are especially useful for the iconographic interpretation of figurative vase painting. In the past, rollouts were created either by manual drawing or photographically. We propo...

Loss of ordered molecular structure in proteins is known to increase their adhesion to surfaces. The aim of this work was to study the stability of norovirus secondary and tertiary structures and its implications for viral adhesion to fresh foods and agrifood surfaces. The pH, ionic strength, and temperature conditions studied correspond to those prevalent in the principal vehicles of viral tra...

A membranous fraction that could synthesize viral RNA in vitro in the presence of magnesium salt, ribonucleotides, and an ATP-regenerating system was isolated from feline calicivirus (FCV)-infected cells. The enzymatically active component of this fraction was designated FCV replication complexes (RCs), by analogy to other positive-strand RNA viruses. The newly synthesized RNA was characterized...

In order to map linear B-cell (LBC) epitopes in the major capsid protein of feline calicivirus (FCV), an expression library containing random, short (100- to 200-bp) fragments of the FCV F9 capsid gene was constructed. Analysis of this library showed it to be representative of the region of the capsid gene that encodes the mature capsid protein. The library was screened by using polyclonal anti...

In order to locate amino acid residues involved in the formation of feline calicivirus (FCV) neutralizing epitopes, we analysed the capsid protein gene of monoclonal antibody neutralization-resistant variants of FCV. Amino acid substitutions in the variants were identified in the two hypervariable regions of the capsid protein. Four linear and two conformational epitopes were located in the reg...

Efficient handling of large polygonal scenes has always been a challenging task and in recent years, view-frustum and occlusion culling have drawn a lot of attention for accomplishing this goal. The problem of how to efficiently organize such scenes for fast image synthesis is widely neglected, although the answer heavily affects the overall performance. In this paper, we present three adapted ...
