Using a mixture of cottonseed hulls and cottonseed meal to replace alfalfa hay in diets for stressed feeder calves
One 28-day receiving experiment was
conducted using 625 exotic × British cross
heifers to evaluate growth performance and
morbidity on receiving diets that contained
either alfalfa hay or a pellet composed of
65% cottonseed hulls and 35% cottonseed
meal as the roughage source. Heifers fed the
cotton byproduct pellet consumed more feed
(P<0.01) but tended to be less efficient than
those fed alfalfa hay. Daily gain was comparable
between diets (P>0.05), and the percentages
of heifers diagnosed, treated, or
retreated for respiratory disease were similar

This work was supported by EPSRC (grants EP/J018139/1, EP/K00445X/1 (NJW), the EPSRC funded CRITICAT Centre for Doctoral Training (Ph.D. studentship to IP; EP/L016419/1) and EPSRC Doctoral Prize Fellowship (CSL)A new method has been developed to enable the modification of the organosolv technical lignin. Using a walnut shell butanol alkoxasolv lignin as a source of high β-O-4 content material, the β-O-4 γ-position has been selectively modified via tosylation, azidation and copper-catalyzed azide-alkyne triazole formation . In addition, extensive model studies were used to aid the detailed characterization of the modified lignin structure. The copper catalyzed click reaction was used to attach modified PEG chains and the resulting lignin-based co-polymer displayed improved thermal stability. This protocol was also used to incorporate a novel BODIPY-type fluorophore, generating a fluorescent lignin. Copper catalytic loadings were effective as low as 0.3 weight% and were found to catalyze the cycloaddition efficiently. This efficient and generic approach to preparing lignin-derived polymers is relevant to the core societal challenge of improving biorefinery efficiency.PostprintPeer reviewe
Catalytic depolymerisation of isolated lignin to fine chemicals: depolymerisation of Kraft lignin
Kraft lignin depolymerisation over Pt/alumina, Rh/alumina and solvolysis was studied under a range of solvent solutions (ethanol/water, isopropanol/water, acetone/water 25:75, 50:50, 75:25 v/v), high temperature (573 K) and pressure (20 barg). The reactions generated mainly non-alkylated phenolic monomers, especially 2-methoxyphenol. In terms of overall yield, solvolysis was shown to be as effective as the catalysed reactions in some experiments. Nevertheless, it was found that for individual molecules a suitable combination of solvent mixture and catalyst resulted in the possibility of target compound generation. To contribute to an understanding of the mechanism of Kraft lignin depolymerisation, kinetic isotopic effects (KIE) were evaluated using fully deuterated and partially deuterated experiments. This revealed hydrogen exchange between the molecules and solvents. In addition, a variety of positive and inverse KIE showed the complexity of lignin depolymerisation and the direct involvement of solvents in those reactions
Urine disinfection and in situ pathogen killing using a Microbial Fuel Cell cascade system
© 2017 Ieropoulos et al. This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Microbial Fuel Cells (MFCs) are emerging as an effective means of treating different types of waste including urine and wastewater. However, the fate of pathogens in an MFC-based system remains unknown, and in this study we investigated the effect of introducing the enteric pathogen Salmonella enterica serovar enteritidis in an MFC cascade system. The MFCs continuously fed with urine showed high disinfecting potential. As part of two independent trials, during which the bioluminescent S. enteritidis strain was introduced into the MFC cascade, the number of viable counts and the level of bioluminescence were reduced by up to 4.43-0.04 and 4.21-0.01 log-fold, respectively. The killing efficacy observed for the MFCs operating under closed-circuit conditions, were higher by 1.69 and 1.72 log-fold reduction than for the open circuit MFCs, in both independent trials. The results indicated that the bactericidal properties of a well performing anode were dependent on power performance and the oxidation-reduction potential recorded for the MFCs. This is the first time that the fate of pathogenic bacteria has been investigated in continuously operating MFC systems
Evidence of Color Coherence Effects in W+jets Events from ppbar Collisions at sqrt(s) = 1.8 TeV
We report the results of a study of color coherence effects in ppbar
collisions based on data collected by the D0 detector during the 1994-1995 run
of the Fermilab Tevatron Collider, at a center of mass energy sqrt(s) = 1.8
TeV. Initial-to-final state color interference effects are studied by examining
particle distribution patterns in events with a W boson and at least one jet.
The data are compared to Monte Carlo simulations with different color coherence
implementations and to an analytic modified-leading-logarithm perturbative
calculation based on the local parton-hadron duality hypothesis.Comment: 13 pages, 6 figures. Submitted to Physics Letters
A nanoparticle-incorporated STING activator enhances antitumor immunity in PD-L1-insensitive models of triple-negative breast cancer
Triple-negative breast cancer (TNBC) has few therapeutic options, and alternative approaches are urgently needed. Stimulator of IFN genes (STING) is becoming an exciting target for therapeutic adjuvants. However, STING resides inside the cell, and the intracellular delivery of CDNs, such as cGAMP, is required for the optimal activation of STING. We show that liposomal nanoparticle-delivered cGAMP (cGAMP-NP) activates STING more effectively than soluble cGAMP. These particles induce innate and adaptive host immune responses to preexisting tumors in both orthotopic and genetically engineered models of basal-like TNBC. cGAMP-NPs also reduce melanoma tumor load, with limited responsivity to anti-PD-L1. Within the tumor microenvironment, cGAMP-NPs direct both mouse and human macrophages (M), reprograming from protumorigenic M2-like phenotype toward M1-like phenotype; enhance MHC and costimulatory molecule expression; reduce M2 biomarkers; increase IFN-γ-producing T cells; augment tumor apoptosis; and increase CD4+ and CD8+ T cell infiltration. Activated T cells are required for tumor suppression, as their depletion reduces antitumor activity. Importantly, cGAMP-NPs prevent the formation of secondary tumors, and a single dose is sufficient to inhibit TNBC. These data suggest that a minimal system comprised of cGAMP-NP alone is sufficient to modulate the tumor microenvironment to effectively control PD-L1-insensitive TNBC
Oralism: a sign of the times? The contest for deaf communication in education provision in late nineteenth-century Scotland
Disability history is a diverse field. In focussing upon children within deaf education in late nineteenth-century Scotland, this essay reflects some of that diversity. In 1880, the International Congress on the Education of the Deaf in Milan stipulated that speech should have ‘preference’ over signs in the education of deaf children. The mode of achieving this, however, effectively banned sign language. Endeavours to teach deaf children to articulate were not new, but this decision placed pressures on deaf institutions to favour the oral system of deaf communication over other methods. In Scotland efforts were made to adopt oralism, and yet educators were faced with the reality that this was not good educational practice for most pupils. This article will consider responses of Scottish educators of deaf children from the 1870s until the beginning of the twentieth century
