Feeding with chicory roots reduces the amount of odorous compounds in colon and rectal contents of pigs

Sixteen pigs (eight entire males and eight females) were given individually two diets, control and control added 25% chopped chicory roots for 2 months before slaughter. Samples were taken from the contents in colon and rectum and subjected to GC-MS analysis for amount of odour impact compounds. The compounds 2-pentanone, ethylbutyrate, propylpropionate, butyric acid, ethyl-2-methylbutyrate, p-cresol, indole and skatole showed a significant difference between the two treatments. The esters, which have relatively pleasant, often fruity odours, increased in the chicory treatment, whereas the malodorous compounds, p-cresol, indole and skatole decreased in the chicory treatment. The measured amounts of compounds were corrected for their odour thresholds as different compounds can have widely different odour thresholds. Principal components analysis was then used to analyse the raw and corrected data results. p-Cresol was the most malodorous compound and together with skatole and indole count as the most malodorous compounds in the colon and rectum cotents. However, butyric acid also had some minor influence. Feeding chicory roots decreased significantly the concentrations of these malodorous compounds, especially if the lowest odour threshold values are used as correction factors

Feeding with chicory roots reduces the amount of odorous compounds in colon contents of pigs

It is known that pure inulin a fructooligosaccharide extracted from chicory roots can: reduce boar taint (skatole in backfat and blood)reduce parasite infection levels when added to specially composed experimental diets. However, the entire chicory roots may, in comparison to inulin: reduce boar taint more effectively improve the taste of cooked meat from both male and female pigs be more effective against parasites when added to normal diet types Improved stable environment due to: the reduced malodour coming from pig stables and manure may possibly lead to environmental benefits for the farmer and the public

Exercise mediates the association between positive affect and 5-year mortality in patients with ischemic heart disease

Background Positive affect has been associated with better prognosis in patients with ischemic heart disease, but the underlying mechanisms remain unclear. We examined whether positive affect predicted time to first cardiac-related hospitalization and all-cause mortality, and whether exercise mediated this relationship in patients with established ischemic heart disease. Methods and Results The sample comprised 607 patients with ischemic heart disease from Holbæk Hospital, Denmark. In 2005, patients completed the Global Mood Scale (GMS) to assess positive affect and a purpose-designed question on exercise. Data on mortality and hospitalization were collected from Danish national registers for the period 2006–2010. Adjusted Cox and logistic regression were used to analyze the mediation model. Because no significant association between positive affect and cardiac-related hospitalization was found, we constructed no mediation model for hospitalization. Importantly, patients with high positive affect had a significantly reduced risk of all-cause mortality (hazard ratio, 0.58; 95% confidence interval, 0.37–0.92; unadjusted analysis) and were more likely to exercise (odds ratio, 1.99; 95% confidence interval, 1.44–2.76; unadjusted analysis; odds ratio, 1.48; 95% confidence interval, 1.03–2.13; adjusted analysis). When controlling for positive affect and other relevant variables, patients engaged in exercise were less likely to die during follow-up (hazard ratio, 0.50; 95% confidence interval, 0.31–0.80; P=0.004). Importantly, exercise acted as a mediator in the relationship between positive affect and mortality. Conclusions Patients with higher levels of positive affect were more likely to exercise and had a lower risk of dying during 5-year follow-up, with exercise mediating the relationship between positive affect and mortality. Interventions aimed at increasing both positive affect and exercise may have better results with respect to patients’ prognosis and psychological well-being than interventions focusing on 1 of these factors alone

Influence of chicory roots /Cichorium intybus L) on boar taint in entire male pigs and female pigs

It is known that pure inulin a fructooligosaccharide extracted from chicory roots can: – reduce boar taint (skatole in backfat and blood) – reduce parasite infection levels when added to specially composed experimental diets • However, the entire chicory roots may, in comparison to inulin: – reduce boar taint more effectively – improve the taste of cooked meat from both male and female pigs – be more effective against parasites when added to normal diet types – contain secondary metabolites that add to the effect of the inulin – be a cheaper solutio

Current Distribution in the Three-Dimensional Random Resistor Network at the Percolation Threshold

We study the multifractal properties of the current distribution of the three-dimensional random resistor network at the percolation threshold. For lattices ranging in size from $8^3$ to $80^3$ we measure the second, fourth and sixth moments of the current distribution, finding {\it e.g.\/} that $t/\nu=2.282(5)$ where $t$ is the conductivity exponent and $\nu$ is the correlation length exponent.Comment: 10 pages, latex, 8 figures in separate uuencoded fil

Learning from the world? Horizontal knowledge flows and geopolitics in international consulting firms

This paper examines the nature of the contemporary multinational corporation (MNC) through a study of the use of knowledge management systems (KMS) in four major international consulting firms. In particular, we explore whether and how such systems facilitate horizontal (inter-subsidiary) flows of knowledge, as described in the network view of the MNC. Our analysis reveals the presence of horizontal flows within the four firms, but flows that are contextually constrained and partly shaped by geopolitical power relations. Thus, our study gives some support to the image of the MNC as a network whilst highlighting the contextual limits of horizontal knowledge transfer and, importantly, the geopolitical conditions under which such knowledge transfer takes place. At the same time, it challenges the claim that consulting firms are model organizations in the area of knowledge management as well as the more negative view that questions the ability of KMS to facilitate knowledge transfer

Low-Energy Universality in Atomic and Nuclear Physics

An effective field theory developed for systems interacting through short-range interactions can be applied to systems of cold atoms with a large scattering length and to nucleons at low energies. It is therefore the ideal tool to analyze the universal properties associated with the Efimov effect in three- and four-body systems. In this "progress report", we will discuss recent results obtained within this framework and report on progress regarding the inclusion of higher order corrections associated with the finite range of the underlying interaction.Comment: Commissioned article for Few-Body Systems, 47 pp, 16 fig

The DNDN, πΣc\pi \Sigma_c interaction in finite volume and the Λc(2595)\Lambda_c(2595) resonance

In this work the interaction of the coupled channels $DN$ and $\pi \Sigma_c$ in an SU(4) extrapolation of the chiral unitary theory, where the $\Lambda_c(2595)$ resonance appears as dynamically generated from that interaction, is extended to produce results in finite volume. Energy levels in the finite box are evaluated and, assuming that they would correspond to lattice results, the inverse problem of determining the phase shifts in the infinite volume from the lattice results is solved. We observe that it is possible to obtain accurate $\pi \Sigma_c$ phase shifts and the position of the $\Lambda_c(2595)$ resonance, but it requires the explicit consideration of the two coupled channels. We also observe that some of the energy levels in the box are attached to the closed $DN$ channel, such that their use to induce the $\pi \Sigma_c$ phase shifts via L\"uscher's formula leads to incorrect results.Comment: 10 pages, 13 figures, accepted for publication in Eur.
