A simplified silver phosphate extraction method for oxygen isotope analysis of bioapatite
(Wiley, 2018-06-21)Rationale: Although phosphatic materials are chemically complex and are prone to exchange oxygen isotopes with their environments, the phosphate (PO43-) component of these materials is robust and retains its original oxygen ... -
Complex Hadamard diagonalisable graphs
(Linear Algebra and its Applications, 2020)In light of recent interest in Hadamard diagonalisable graphs (graphs whose Laplacian matrix is diagonalisable by a Hadamard matrix), we generalise this notion from real to complex Hadamard matrices.We give some basic ... -
On split graphs with four distinct eigenvalues
(Discrete Applied Mathematics, 2020)It is a well-known fact that a graph of diameter d has at least d + 1 eigenvalues. A graph is d-extremal, if it has diameter d and exactly d+1 eigenvalues. A graph is split if its vertex set can be partitioned into a ... -
The Karpelevic region revisited
(Journal of Mathematical Analysis and Applications, 2020)We consider the Karpelevic region \Theta_n in the complex plane consisting of all eigenvalues of all stochastic matrices of order n. We provide an alternative characterisation of \Theta_n that sharpens the original description ... -
The effectiveness of matching sales influence tactics to consumers’ avoidance versus approach shopping motivations
(Emerald Group Publishing Limited, 2017)Abstract Purpose - Adaptive selling can help build positive relationships between sales agents and consumers. The literature shows that consumers respond positively to sales agents under approach, but not avoidance ... -
The Right Kind of Evidence - Integrating, Measuring, and Making it Count in Health Equity Research
(Spring Verlag, 2012)As health equity researchers, we need to produce research that is useful, policy-relevant, able to be understood and applied, and uses integrated knowledge translation (KT) approaches. The Manitoba Centre for Health Policy ... -
A Systematic Review of the Effect of Early Interventions for Psychosis on the Usage of Inpatient Services
(Oxford University Press, 2015)Objectives: To review and synthesize the currently available research on whether early intervention for psychosis programs reduce the use of inpatient services. Methods: A systematic review was conducted using keywords ... -
Tests of two functions of alarm calls given by yellow warblers during nest defence
(2003-10-31)During nest defence, yellow warblers (Dendroica petechia) give "seet" and "chip" calls. Seet calls are given preferentially toward brood parasitic brown-headed cowbirds (Molothrus ater) during the yellow warblers' egg-laying ... -
Genetic elucidation of host use by individual sympatric bronzed cowbirds (Molothrus aeneus) and brown-headed cowbirds (M-ater)
(2006-09-30)Species of avian brood parasites that use one or several species of hosts are called host specialists and generalists, respectively. To determine host use of individual bronzed cowbirds, Molothrus aeneus (Wagler, 1829), ... -
Genetic and temporal patterns of multiple parasitism by brown-headed cowbirds (Molothrus ater) on song sparrows (Melospiza melodia)
(2003-02-28)Identifying the factors used by an avian brood parasite to select host nests is important in understanding the determinates of individual reproductive success, yet such factors are poorly known for most parasitic species. ... -
Experiments on egg discrimination in two North American corvids: further evidence for retention of egg ejection
(2004-09-30)In the absence of brood parasitism in North America, black-billed magpies, Pica hudsonia (Sabine, 1822), and yellow-billed magpies, Pica nuttalli (Audubon, 1837), may have retained egg-discrimination behaviour that evolved ... -
Comparison of the rapid insulin sensitivity test (RIST), the insulin tolerance test (ITT), and the hyperinsulinemic euglycemic clamp (HIEC) to measure insulin action in rats
(2002-08-31)The objective was to compare the ability of the rapid insulin sensitivity test (RIST), the hyperinsulinemic euglycemic clamp (HIEC), and the insulin tolerance test (ITT) to detect hepatic insulin sensitizing substance ... -
Thermophilic anaerobic acid digestion of biosolids: hydrolysis, acidification, and optimization of retention time of acid digestion
(2006-05-31)The objective of the study was the optimization of the retention time in a thermophilic acid digestion system. To achieve this optimization, acidification index defined as the ratio between acidification rate and hydrolysis-rate ... -
Wastewater biosolids: an overview of processing, treatment, and management
(2001-01-31)Treated as a valuable resource, municipal sludge, often today referred to as biosolids, is processed through a variety of novel unit operations leading to a safe, aesthetically pleasing, and sought-after product. The design ... -
Nitrifying bacteria addition into reactors operating near washout conditions for nitrification
(2005-07-31)Sequencing batch reactors, at 10 degrees C, operating near the minimum solids retention time (washout conditions) for nitrification, were seeded daily with nitrifying biomass acclimated to 10 and 20 degrees C. Effluent ... -
Pattern of insulin delivery affects hepatic insulin sensitizing substance (HISS) action and insulin resistance
(2004-12-31)Hepatic insulin sensitizing substance (HISS) action accounts for 55% of the glucose disposal effect of a bolus of insulin in the fed state. To determine the effect of continuous versus pulsatile insulin delivery on HISS ... -
Nitric oxide inhibits norepinephrine-induced hepatic vascular responses but potentiates hepatic glucose output
(2000-01-31)We previously reported that sympathetic nerve-induced vasoconstriction in the intestine resulted in shear stress induced release of nitric oxide (NO) that led to presynaptic inhibition of transmitter release. In contrast, ... -
Insulin sensitivity regulated by feeding in the conscious unrestrained rat
(2002-01-31)Hepatic insulin sensitizing substance (HISS), a putative hormone released from the liver in response to insulin in fed animals, accounts for 50-60% of insulin action. HISS release is regulated by permissive control of the ... -
Increased incidence of hepatic insulin-sensitizing substance (HISS)-dependent insulin resistance in female rats prenatally exposed to ethanol
(2005-04-30)Insulin causes the release of the hepatic insulin-sensitizing substance (HISS) from the liver. Hepatic parasympathetic nerves play a permissive role in the release of HISS. HISS-dependent insulin resistance (HDIR) occurs ... -
Glucose disposal by insulin, but not IGF-1, is dependent on the hepatic parasympathetic nerves
(2000-10-31)Insulin-like growth factor-1 (IGF-1) has many insulin-like activities, including stimulation of glucose uptake in skeletal muscle. However, those with diabetes or chronic liver disease are insulin resistant but show a ...
