The application of animal manure as a source of plant nutrients requires the determination of the amount and pattern of nutrient mineralization from manure.A laboratory incubation study was conducted to investigate the influence of lignite amendment and lignite type on carbon(C)and nitrogen(N)mineralization in raw(feedstock)and composted cattle manure following application to soil at 30 and 60 t ha^(-1).The mineralization of C and N was determined by measuring changes in CO_(2) evolution and mineral N(NH_(4)^(+)-N+NO_(3)^(-)-N)over 40 *** results showed that lignite amendment suppressed the amount of manure C mineralized in both feedstock and compost,with the effect being more pronounced in the *** the 40-d incubation,the percentage of applied C mineralized was 26.4%-27.8%and 16.3%-21.4%in unamended and lignite-amended feedstocks,*** corresponding C mineralized in the composts was 12.4%-14.1%and 3.5%-6.5%.Lignite had no significant effect on the net N mineralized in compost(4.8%-6.7%and2.5%-7.8%in unamended and lignite-amended composts,respectively).Lignite had either no effect or increased the net N mineralized in feedstock(from3.2%-8.7%without lignite to 10.4%-13.5%)depending on the type of lignite *** study suggests that using lignite-amended manure,especially when composted,has the potential to build up soil organic C without limiting the availability of mineral N.

This paper presents a new model of scenarios, dedicated to the specification and verification of system be- haviours in the context of software product lines （SPL）. We draw our inspiration from some techniques that are mostly used in the hardware community, and we show how they could be applied to the verification of software components. We point out the benefits of synchronous languages and mod- els to bridge the gap between both worlds.

The sequence of Gidl （a gene for a gibberellin （GA） receptor from rice） was used to identify a putative orthologue from barley. This was expressed in E. coil, and produced a protein that was able to bind GA in vitro with both structural specificity and saturability. Its potential role in GA responses was investigated using barley mutants with reduced GA sensitivity （gsel mutants）. Sixteen different gsel mutants each carried a unique nucleotide substitution in this sequence. In all but one case, these changes resulted in single amino acid substitutions, and, for the remaining mutant, a substitution in the 5＇ untranslated region of the mRNA is proposed to interfere with translation initiation. There was perfect linkage in segregating populations between new mutant alleles and the gsel phenotype, leading to the conclusion that the putative GId1 GA receptor sequence in barley corresponds to the Gsel locus. determination of endogenous GA contents in one of the mutants revealed enhanced accumulation of bioactive GA1, and a deficit of C20 GA precursors. All of the gsel mutants had reduced sensitivity to exogenous GA3, and to AC94377 （a GA analogue） at concentrations that are normally ＇saturating＇, but, at much higher concentrations, there was often a considerable response. The comparison between barley and rice mutants reveals interesting differences between these two cereal species in GA hormonal physiology.

AIM To understand the role of knowledge as a promoter of hepatitis C virus(HCV) screening among primary care physicians(PCP).METHOdS A 45-item online questionnaire assessing knowledge of HCV natural history, risk factors, and treatment was distributed to 163 PCP. Logistic regression, adjusted for survey responses, assessed associations between PCP knowledge of HCV natural history and treatment and birth cohort(i.e., birth between 1945 and 1965) screening. Response stratification and weighting were used to account for nonresponse and to permit extension of responses to the entire survey population. Associations between various predictors including demographic characteristics, level of training, and HCV treatment experience and HCV knowledge were *** Ninety-one individuals(55.8%) responded. Abnormal liver enzymes(49.4%), assessment of HCV-related risk factors(30.6%), and birth cohort membership(20%) were the leading HCV screening indications. Most PCP(64.7%) felt that the combination of risk-factor and birth cohort screening utilizing a self-administered survey while awaiting the physician(55.3%) were the most efficient screening practices. Implementation of birth cohort screening was associated with awareness of the recommendations(P-value = 0.01), knowledge of HCV natural history(P-value d prior management of HCV patients(P-value dge of HCV treatment was also knowledgeable about HCV natural history(P-value d screening recommendations was associated with HCV treatment knowledge(P-value = 0.03).CONCLUSION Comprehensive knowledge of HCV is critical to motivate HCV screening. PCP-targeted educational interventions are required to expand the HCV workforce and linkageto-care opportunities as we seek global HCV eradication.

In healthy humans, ammonia circulates in the bloodstream at a concentration around 11–32 μmol/L. Whether ammonia plays any physiological role has been unknown until a recent report published in Nature Metabolism.1 Ammonia, long thought to be a toxic waste product of amino acid metabolism, needs to be excreted from the human body as urea. Intriguingly, in this paper, Cheng et al1 for the first time reported that ammonia is not a waste product;rather, it is an unprecedented signaling molecule tying glucose and glutamine to lipid production in human cells. This study revealed that ammonia released from glutamine triggers a cascade of cellular processes leading to the activation of lipogenesis machinery for lipid production (Fig. 1). This discovery has major implications for developing treatments for human diseases such as cancers and metabolic syndromes, as dysregulated metabolism is a hallmark of these diseases.

This paper describes an experimental investigation on the flow characteristics within a rotating cylinder containing a rolling bed of sand. The axis of the cylinder was horizontal and there was no axial bulk flow of particles. The velocity field of the gas flowing through the cylinder was measured by hot-wire anemometry. The measurements indicate that the velocity field is asymmetric with respect to a diameter perpendicular to the granular bed. CFd calculations confirm this finding. The gas velocity profiles are crucial in determining heat transfer from gas to solid.
