Yajing Ban, Nazir Ahmad Khan, Peiqiang Yu
The increased utilization of Brassica carinata in the biofuel industry in Canada has resulted in the large scale production of coproducts that can be potentially exploited as alternative protein ingredient in dairy ration. The objectives of this study were to investigate the nutritive value of carinata presscake and meal for dairy cows in terms of (1) nutrient and anti-nutrient composition; (2) rumen degradation kinetics of organic matter (OM), crude protein (CP) and neutral detergent fiber; (3) hourly effective degradation ratio and potential N to energy synchronization; (4) intestinal digestion of rumen undegraded protein (RUP); and (5) total metabolizable protein (MP) supply to the small intestine...

A cogeneration system for simultaneously producing synthetic natural gas (SNG) and electric power from municipal solid waste (MSW) is developed. This process provides a disposal method for MSW that is environmentally sustainable and uses as an alternative energy sources. Rather than converting all of the synthesis gas into end products, in the proposed system the unconverted gas is recovered for power generation in a combined-cycle unit. The overall efficiency of the proposed system is 36.33%. The energy efficiency of this system is approximately 8...

A techno-economic analysis (TEA) was performed on glucosamine and lipid production from a marine diatom Cyclotella sp. in raceway open pond (RWP) and tubular photobioreactor (PBR) cultivation systems. Two PBR operating schemes were assessed: one to produce high lipid (HL) content, and another to produce high chitin (HC) content. In order to generate 1kg of glucosamine, 9700kg (RWP)/1050kg (PBR HL) freshwater, 40kg CO2, 0.70kg nitrogen, 0.18kg phosphorus, and 1.2kg silicon nutrients are required for algae cultivation with water and nutrient recovery...

University engagement with mental health services has traditionally been informed by the vocational and pedagogical links between the two sectors. However, a growth in the interest in public history and in the history of mental healthcare has offered new opportunities for those in the humanities to engage new audiences and to challenge perceptions about care in the past. The introduction of the 'impact agenda' and related funding streams has further encouraged academics to contribute to historical debates, and to those concerning current services...

Biodiversity conservation is one of the grand challenges facing society. Many people interested in biodiversity conservation have a background in wildlife biology. However, the diverse social, cultural, political, and historical factors that influence the lives of people and wildlife can be investigated fully only by incorporating social science methods, ideally within an interdisciplinary framework. Cultural hierarchies of knowledge and the hegemony of the natural sciences create a barrier to interdisciplinary understandings...

Although the purchase price of cellulosic feedstocks is competitive with petroleum on an energy basis, the cost of lignocellulose conversion to ethanol using today's technology is high. Cost reductions can be pursued via either in-paradigm or new-paradigm innovation. As an example of new-paradigm innovation, consolidated bioprocessing using thermophilic bacteria combined with milling during fermentation (cotreatment) is analyzed. Acknowledging the nascent state of this approach, our analysis indicates potential for radically improved cost competitiveness and feasibility at smaller scale compared to current technology, arising from (a) R&D-driven advances (consolidated bioprocessing with cotreatment in lieu of thermochemical pretreatment and added fungal cellulase), and (b) configurational changes (fuel pellet coproduction instead of electricity, gas boiler(s) in lieu of a solid fuel boiler)...

Open-water unit process wetlands host a benthic diatomaceous and bacterial assemblage capable of nitrate removal from treated municipal wastewater with unexpected contributions from anammox processes. In exploring mechanistic drivers of anammox, 16S rRNA gene sequencing profiles of the biomat revealed significant microbial community shifts along the flow path and with depth. Notably there was an increasing abundance of sulfate reducers (Desulfococcus and other Deltaproteobacteria) and anammox microorganisms (Brocadiaceae) with depth...

To convert the lipopeptide non-producer strain Bacillus subtilis pB2 into a plipastatin and surfactin coproducer, a gene expression cassette composed of a constitutive promoter (P43), functional gene sfp, and pleiotropic regulatory gene degQ was integrated into the chromosomal amyE locus of strain B. subtilis pB2 by homologous recombination, which generated a plipastatin and surfactin co-producer. Thirteen plipastatins and fifteen surfactins were identified in lipopeptide extracts using analytical techniques, and their effects on microorganisms were described by microscopic, cytoskeleton analysis and flow-cytometry, respectively...

Mollusc shells are composed of more than 95% calcium carbonate and less than 5% organic matrix consisting mostly of proteins, glycoproteins and polysaccharides. In this study, we investigated the effects of matrix macromolecular components extracted from the shells of two edible molluscs of economic interest, i.e., the blue mussel Mytilus edulis and the Pacific oyster Crassostrea gigas. The potential biological activities of these organic molecules were analysed on human dermal fibroblasts in primary culture...

One-carbon metabolism is an ubiquitous metabolic pathway that encompasses the reactions transferring formyl-, hydroxymethyl- and methyl-groups bound to tetrahydrofolate for the synthesis of purine nucleotides, thymidylate, methionine and dehydropantoate, the precursor of coenzyme A. An alternative cyclic pathway was designed that substitutes 4-hydroxy-2-oxobutanoic acid (HOB), a compound absent from known metabolism, for the amino acids serine and glycine as one-carbon donors. It involves two novel reactions, the transamination of l-homoserine and the transfer of a one-carbon unit from HOB to tetrahydrofolate releasing pyruvate as coproduct...

The disproportionation of NaH2PO2, NaH2PO3, Na2HPO3 and their mixtures was studied by TG-DSC, XRD and (31)P NMR. NaH2PO2 reacted in three steps to yield PH3, Na5P3O10 and H2 by disproportionation and oxidation with water released in condensation reactions. In the first step at 310 °C NaH2PO2 reacted to yield PH3, Na2H2P2O5, Na2HPO3, Na4P2O7 and H2. H2 rather than H2O was the coproduct of the disproportionation, because H2O oxidized hypophosphite and phosphite at elevated temperatures, in agreement with DFT results that show that the reaction of H3PO3 with H2O is exothermic...

We present herein a detailed study of the conversion of a nickel(II) diamide precursor to size-tunable, monodisperse nickel nanoparticles (NPs). The thermal decomposition of nickel(II) dioleylamide, synthesized either independently or in situ, results in the formation of Ni NPs without coproduction of water. Mechanistic studies were conducted on the stability and reduction pathway of the Ni(II) precursor, and on consequent particle formation. Varying the ratio of TOP to nickel permits size tunability, resulting in nanoparticles ranging in size from 4 nm to 11 nm in diameter...

BACKGROUND: Pediatric chronic illness care models are traditionally organized around acute episodes of care and may not meet the needs of patients and their families. Interventions that extend the patient-clinician interaction beyond the health care visit, allow for asynchronous and bidirectional feedback loops that span visits and daily life, and facilitate seamless sharing of information are needed to support a care delivery system that is more collaborative, continuous, and data-driven...

The aim was to compare the distribution of ANCs in purple and blue corn coproducts from three conventional corn fractionation processes and linking ANC partitioning in different coproducts to corn kernel phenotype. Total monomeric anthocyanin (TA) from purple corn extract was 4933.1±43.4mg cyanidin-3-glucoside equivalent per kg dry corn, 10 times more than blue corn. In dry milled purple corn, maximum ANCs were present in the pericarp (45.9% of total ANCs) and in wet-milling they were concentrated in steeping water (79...

This study evaluates the environmental impacts of biorefinery products using consequential (CLCA) and attributional (ALCA) life cycle assessment (LCA) approaches. Within ALCA, economic allocation method was used to distribute impacts among the main products and the coproducts, whereas within the CLCA system expansion was adopted to avoid allocation. The study seeks to answer the questions (i) what is the environmental impacts of process integration?, and (ii) do CLCA and ALCA lead to different conclusions when applied to biorefinery?...

The aim of this study was to evaluate the bioactivity of flavonoids extracted from sweet-cherry stems which are often used by a traditional system of medicine to treat gastro-intestinal and urinary tract infections but lacking any consistent scientific evidence; moreover the information about the class of phenolics, their content and the potential bioactivity of such material is very scarce. Thus, in this context, we have set a research study in which we evaluated the profile and content of phenolics extracted from sweet-cherry stems through a conventional (70ºC and 20 min) and ultrasound assisted extraction (40 kHz, room temperature and 20 min)...
