Analysis of latent tuberculosis and mycobacterium avium infection data using mixture models
(BioMed Central, 2006-09-28)
Background: Estimation of the frequency of latent tuberculosis infection (LTBI) is difficult in areas with low tuberculosis infection rates and high exposure to non-tuberculous mycobacteria (NTM), including BCG vaccination. ...
Ab initio calculation of low-energy collective charge-density excitations in MgB2
(American Physical Society, 2009-08)
We present ab initio time-dependent density-functional theory calculation results for low-energy collective electron excitations in MgB2. The existence of a long-lived collective excitation corresponding to coherent charge ...
Survey of the fatty acid composition of Canadian beef: Backfat and longissimus lumborum muscle
(Agricultural Institute of Canada, 2009-09)
[EN]A survey of Canadian retail beef was undertaken with emphasis on the trans fatty acid (TFA) and conjugated linoleic acid (CLA) isomers, and compared with current health recommendations. Thirty striploin steaks were ...
Subcutaneous fat composition of youthful and mature Canadian beef: emphasis on individual conjugated linoleic acid and trans-18:1 isomers
(Agricultural Institute of Canada, 2008-12)
[EN]A comprehensive evaluation of the fatty acid composition of subcutaneous adipose tissue from beef cattle produced in western Canada was undertaken to determine if the current Canadian grading system is able to distinguish ...
Phenotypic correlations of fatty acid composition among intramuscular, subcutaneous and intermuscular fat tissues in concentrate-fed beef cattle of differing genotypes
(Agricultural Institute of Canada, 2009-03)
[EN]In an attempt to predict intramuscular fatty acid composition using easily accessible fat depots, between-tissue correlations were studied in 75 Asturiana de los Valles bulls with different levels of muscular hypertrophy, ...
Rapid determination of total CLA concentration in beef fat
(Agricultural Institute of Canada, 2007-06)
[EN]Conjugated linoleic acid (CLA) has many potential healthful properties, and beef is naturally enriched with CLA. Simple and rapid methods to measure total CLA were investigated to enable sorting of beef carcasses with ...
Model-matching-based control of the Beverton-Holt equation in Ecology
(Hindawi Publishing Corporation, 2008)
Beverton-Holt equation of Ecology has a prescribed solution. The way used to achieve the tracking objective is the design of a carrying capacity through a feedback law so that the prescribed reference sequence, which defines ...
Adaptive control of single-input single-output hybrid systems possessing interacting discrete- and continuous-time dynamics
(Hindawi Publishing Corporation, 2005)
This paper deals with the problem of synthesizing a robust adaptive controller for a specific class of single-input single-output (SISO) time-invariant hybrid controlled object (plant) which can operate under bounded ...
Stability Results for Switched Linear Systems with Constant Discrete Delays
(Hindawi Publishing Corporation, 2008)
This paper investigates the stability properties of switched systems possessing several parameterizations (or configurations) while being subject to internal constant point delays. Some of the stability results are formulated ...
On the Global Asymptotic Stability of Switched Linear Time-Varying Systems with Constant Point Delays
(Hindawi Publishing Corporation, 2008)
This paper investigates the asymptotic stability of switched linear time-varying systems with constant point delays under not very stringent conditions on the matrix functions of parameters. Such conditions are their ...
