A PERFORMANCE EVALUATION OF FIVE SWEETPOTATO SHIPPING CONTAINERS

Using a six x six latin square experimental design, five box types in two different markets were evaluated over a six-week period in 1986 to determine if sweetpotato arrival damage could be reduced through use of alternative shipping containers. Findings indicated that skinning, cut and break damage, and bruising could be reduced through use of either a 40-pound container or the 45-pound MUM box rather than using the current 50-pound box. Economic considerations, receiver preferences, and the actions of shippers resulted in the selection of a 40-pound shipping carton as the new standard for the North Carolina sweetpotato industry.Agribusiness,

Bulletin No. 211 - Silage Corn Varieties for Utah

Utah is rapidly developing an important dairy industry. In addition to homegrown hay and grain, there must be some form of succulence. Pasturage is the common way of furnishing fresh feed in summer. In certain regions, silage and beet pulp are the winter forms. With a scarcity of beet pulp, silage corn is likely to be an important crop in the Great Salt Lake and Utah Lake Valleys, where corn does well. The data presented in this publication are related to the choice of a corn variety for ensilage

Elite male Flat jockeys display lower bone density and lower resting metabolic rate than their female counterparts: implications for athlete welfare

To test the hypothesis that daily weight-making is more problematic to health in male compared with female jockeys, we compared the bone-density and resting metabolic rate (RMR) in weight-matched male and female Flat-jockeys. RMR (kcal.kg-1 lean mass) was lower in males compared with females as well as lower bone-density Z-scores at the hip and lumbar spine. Data suggest the lifestyle of male jockeys’ compromise health more severely than females, possibly due to making-weight more frequently

RISK PERCEPTIONS AND MANAGEMENT RESPONSES: PRODUCER-GENERATED HYPOTHESES FOR RISK MODELING

Farm level risk analyses have used price and yield variability almost exclusively to represent risk. Results from a survey of 149 agricultural producers in 12 states indicate that producers consider a broader range of sources of variability in their operations. Significant differences exist among categories with respect to the importance of the sources of variability in crop and livestock production. Producers also used a variety of management responses to variability. There were significant difference among categories in the importance given to particular responses and their use of them. These results have implications for research, extension, and policy programs.Risk and Uncertainty,

Defining a baseline complexity model for ERP systems over SaaS

Our research investigates applying the Software as a Service (SaaS) model for hosted applications to more complex business systems such as an Enterprise Resource Management System (ERP). This application of the service model is still in its infancy and we present some challenges to the technology. We will initially be defining a measure of complexity for business systems and applying this as a baseline to complex business systems within a pure SaaS model on the cloud, considering the elements making up SaaS and inter-relating these with this definition of business complexity. In this research we will be applying elements of Complex Systems Theory, Network Complexity Theory and Programmatic Complexity Models, in extending these for our own application to this service model within this complex business context

Lepidosperma prospectum (Cyperaceae), a new species from Sydney coastal heath and notes on usage of sword sedges

Lepidosperma prospectum G.T.Plunkett & R.L.Barrett (Cyperaceae tribe Schoeneae) is here described as a new species in the Sydney region of New South Wales. It is highly restricted in distribution, occurring at Manly (Sydney Harbour National Park), Kamay Botany Bay National Park and Royal National Park in dense coastal shrublands behind coastal cliffs. These locations are within the traditional lands of the Gamaragal, Gweagal and Dharawal people respectively. Joseph Banks and Daniel Solander were the first Europeans to explore the flora of New South Wales in 1770 around Botany Bay but they did not collect this species. Lepidosperma prospectum is superficially similar to L. sieberi Kunth, which occurs in adjacent habitats, but molecular data have shown that it is more closely allied to Western Australian species. A brief review of recorded indigenous and European knowledge and utilisation of the genus Lepidosperma Labill. is presented to highlight the varied uses of the genus

Bulk Viscosity, Decaying Dark Matter, and the Cosmic Acceleration

We discuss a cosmology in which cold dark-matter particles decay into relativistic particles. We argue that such decays could lead naturally to a bulk viscosity in the cosmic fluid. For decay lifetimes comparable to the present hubble age, this bulk viscosity enters the cosmic energy equation as an effective negative pressure. We investigate whether this negative pressure is of sufficient magnitude to account fo the observed cosmic acceleration. We show that a single decaying species in a flat, dark-matter dominated cosmology without a cosmological constant cannot reproduce the observed magnitude-redshift relation from Type Ia supernovae. However, a delayed bulk viscosity, possibly due to a cascade of decaying particles may be able to account for a significant fraction of the apparent cosmic acceleration. Possible candidate nonrelativistic particles for this scenario include sterile neutrinos or gauge-mediated decaying supersymmetric particles.Comment: 7 pages, 4 figure

Deacylated tRNA is released from the E site upon A site occupation but before GTP is hydrolyzed by EF-Tu

The presence or absence of deacylated tRNA at the E site sharply influences the activation energy required for binding of a ternary complex to the ribosomal A site indicating the different conformations that the E-tRNA imparts on the ribosome. Here we address two questions: (i) whether or not peptidyltransferase—the essential catalytic activity of the large ribosomal subunit—also depends on the occupancy state of the E site and (ii) at what stage the E-tRNA is released during an elongation cycle. Kinetics of the puromycin reaction on various functional states of the ribosome indicate that the A-site substrate of the peptidyltransferase center, puromycin, requires the same activation energy for peptide-bond formation under all conditions tested. We further demonstrate that deacylated tRNA is released from the E site by binding a ternary complex aminoacyl-tRNA•EF-Tu•GDPNP to the A site. This observation indicates that the E-tRNA is released after the decoding step but before both GTP hydrolysis by EF-Tu and accommodation of the A-tRNA. Collectively these results reveal that the reciprocal linkage between the E and A sites affects the decoding center on the 30S subunit, but does not influence the rate of peptide-bond formation at the active center of the 50S subunit
