Potential loss of nutrients from different rearing strategies for fattening pigs on pasture

Nutrient load and distribution on pasture were investigated with fattening pigs that: 1) spend a proportion of or their entire life on pasture, 2) were fed either restrictively or ad libitum, and 3) were weaned at different times of the year. The N and P retention in pigs decreased the longer they were kept on pasture. The contents of soil inorganic N and exchangeable K were significantly raised compared to the soil outside the enclosures but with no differences between treatments. Pig grazing did not affect extractable soil P. Regular moving of huts, feeding and water troughs was effective in ensuring that nutrients were more evenly distributed on the paddocks. Grass cover, as determined by spectral reflectance, was not related to the experimental treatments but only to time of year. During spring and summer, grass was present in parts of the paddocks, whereas during autumn and winter the pigs kept grass cover below 10%. Fattening pigs on pasture carries a high risk of nutrient loss and it is concluded that the most environmentally acceptable way of keeping fattening pigs on pasture involves a combination of reduced dietary N intake, reduced stocking rate and seasonal rather than all year production

An exploratory study into the role and interplay of intrinsic and extrinsic cues in Australian consumers’ evaluations of fish.

This study explores the role and interplay of intrinsic and extrinsic cues when evaluating fish quality and in shaping consumers' attitudes toward fish consumption. A sensory analysis of nine different fish including five variants of barramundi was conducted to determine how consumers evaluated the fish on intrinsic cues. Focus groups were then conducted to explore the impact of extrinsic cues on attitudes and purchase intentions. While the sensory analysis revealed distinct differences between barramundi variants on intrinsic cues (notably taste), the focus groups revealed that, as a brand, barramundi is perceived much more favourably and consistently. Consumers used extrinsic cues, particularly country of origin, as surrogate indicators of quality. Aquaculture producers need to ensure intrinsic product quality and consistency, as while consumers use the extrinsic cue of "Australian grown" as a surrogate indicator of quality, as their familiarity and confidence with seafood grows, this overreliance on extrinsic cues may diminish

Multi-Site Observations of the DAV White Dwarf R 548

The pulsating DA white dwarf R 548 was observed for 46 h in October 1993 in an eight-site campaign. New peaks near the known doublets in the Fourier transform are found

Search for jet extinction in the inclusive jet-pT spectrum from proton-proton collisions at s=8 TeV

Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.The first search at the LHC for the extinction of QCD jet production is presented, using data collected with the CMS detector corresponding to an integrated luminosity of 10.7  fb−1 of proton-proton collisions at a center-of-mass energy of 8 TeV. The extinction model studied in this analysis is motivated by the search for signatures of strong gravity at the TeV scale (terascale gravity) and assumes the existence of string couplings in the strong-coupling limit. In this limit, the string model predicts the suppression of all high-transverse-momentum standard model processes, including jet production, beyond a certain energy scale. To test this prediction, the measured transverse-momentum spectrum is compared to the theoretical prediction of the standard model. No significant deficit of events is found at high transverse momentum. A 95% confidence level lower limit of 3.3 TeV is set on the extinction mass scale

Perspective on Oncogenic Processes at the End of the Beginning of Cancer Genomics

The Cancer Genome Atlas (TCGA) has catalyzed systematic characterization of diverse genomic alterations underlying human cancers. At this historic junction marking the completion of genomic characterization of over 11,000 tumors from 33 cancer types, we present our current understanding of the molecular processes governing oncogenesis. We illustrate our insights into cancer through synthesis of the findings of the TCGA PanCancer Atlas project on three facets of oncogenesis: (1) somatic driver mutations, germline pathogenic variants, and their interactions in the tumor; (2) the influence of the tumor genome and epigenome on transcriptome and proteome; and (3) the relationship between tumor and the microenvironment, including implications for drugs targeting driver events and immunotherapies. These results will anchor future characterization of rare and common tumor types, primary and relapsed tumors, and cancers across ancestry groups and will guide the deployment of clinical genomic sequencing

Searches for electroweak neutralino and chargino production in channels with Higgs, Z, and W bosons in pp collisions at 8 TeV

Searches for supersymmetry (SUSY) are presented based on the electroweak pair production of neutralinos and charginos, leading to decay channels with Higgs, Z, and W bosons and undetected lightest SUSY particles (LSPs). The data sample corresponds to an integrated luminosity of about 19.5 fb(-1) of proton-proton collisions at a center-of-mass energy of 8 TeV collected in 2012 with the CMS detector at the LHC. The main emphasis is neutralino pair production in which each neutralino decays either to a Higgs boson (h) and an LSP or to a Z boson and an LSP, leading to hh, hZ, and ZZ states with missing transverse energy (E-T(miss)). A second aspect is chargino-neutralino pair production, leading to hW states with E-T(miss). The decays of a Higgs boson to a bottom-quark pair, to a photon pair, and to final states with leptons are considered in conjunction with hadronic and leptonic decay modes of the Z and W bosons. No evidence is found for supersymmetric particles, and 95% confidence level upper limits are evaluated for the respective pair production cross sections and for neutralino and chargino mass values

Health-related attitudes as a basis for segmenting European fish consumers

This paper identifies and profiles consumer segments based on health-related attitudes. Cross-sectional data were collected in 2008 through a pan-European consumer survey (n = 2400) with samples representative for age and region in France, Poland and Spain. Four distinct consumer segments based on health-related attitudes are identified: low interest in healthy eating consumers (29.4%), positive health enthusiasts (28.2%), health strivers (35.0%) and health uninvolved (7.4%). The segments differ significantly with respect to fish consumption, attitudes and knowledge about the health benefits of fish, interest in potential informational cues when purchasing fish, and individual socio-demographic characteristics. The segment low interest in healthy eating is characterised by younger age, more males, higher BMI, low fish consumption and low interest in information, and herewith emerges as a relevant though difficult to reach segment from a food and health policy perspective. Positive health enthusiasts and health strivers have a strong involvement with food, and a strong interest in healthy eating. Both segments have a very favourable disposition towards fish consumption, which would fit with their focus to either stay healthy (positive health enthusiasts) or improve their current health status (health strivers). Health uninvolved consumers do not care strongly about health in general; though attach high importance to eating healthily

Impact of consumers' health beliefs, health involvement and risk perception on fish consumption: a study in five European countries

Purpose – The purpose of this paper is to investigate the impact of consumers' health beliefs, health involvement, and risk perception on fish consumption behaviour in five European countries. Design/methodology/approach – Cross-sectional data were collected through a pan-European consumer survey (n=4,786) with samples representative for age and region in Belgium, The Netherlands, Denmark, Spain and Poland. First, the cross-cultural validity and cross-cultural differences in health beliefs, health involvement and risk perception in relation to fish have been tested. Next, structural equation modelling (LISREL) was used in order to simultaneously estimate the strength and direction of relationships between health beliefs, health involvement and risk perception in relation to fish consumption. Findings – Health involvement links up indirectly with subjective health and with total fish consumption, in both cases through increased interest in healthy eating. Interest in healthy eating positively and directly influences fish consumption. Increased risk perception from fish consumption negatively influences consumers' subjective health, as well as consumers' total fish consumption. Finally, subjective health positively relates to satisfaction with life. Research limitations/implications – This study focused on fish as a product category, and included only a limited number of attitudinal constructs. Originality/value – This paper provides a unique model relating health beliefs, health involvement and risk perception to fish consumption, which has been tested and validated using a large pan-European consumer sample.</p
