RATIONALE Increased bacterial concentration (load) in the lower airways and new bacterial strain acquisition have been posited as mechanisms for chronic obstructive pulmonary disease (COPD) exacerbations. Bacterial concentrations are higher during exacerbation than during stable
Numerical Dynamic Analysis of Beams on Nonlinear Elastic Foundations under Harmonic Moving Load
As a main background practical context of the present numerical investigation, the appropriate description of track vibrations induced by high-speed trains looks crucial in contemporary railway engineering. The present paper is concerned with the modelization of the transient dyn
Observations on the Mechanism of Decreased Tubular Reabsorption of Sodium and Water during Saline Loading.
It has been demonstrated by several recent studies that the regulation of sodium excretion involves factors other than the total filtered load of sodium and the renal tubular effects of mineralo-corticoids. Contrary to earlier suggestions that an increase in the filtered load of
Nonlinear Response of Infinite Beams on a Multilayer Tensionless Extensible Geo-Synthetic: Reinforced Earth Beds under Moving Load
Abstract—In this paper, analysis of an infinite beam resting on multilayer tensionless extensible geosynthetic reinforced granular fill-poor soil system overlying soft soil strata under moving load with constant velocity is presented. The beam is subjected to a concentrated load
What is the best method for assessing lower limb force-velocity relationship?
This study determined the concurrent validity and reliability of force, velocity and power measurements provided by accelerometry, linear position transducer and Samozino's methods, during loaded squat jumps. 17 subjects performed squat jumps on 2 separate occasions in 7 loading
Dose-dependence of 4-aminopyridine plasma concentrations and electrophysiological effects in dogs : potential relevance to ionic mechanisms in vivo.
BACKGROUND Previous investigators have administered 4-aminopyridine (4AP) to dogs to evaluate the role of transient outward current (I(to)) in vivo; however, plasma concentrations of 4AP were not measured, and it is therefore uncertain which cardiac ion channels were blocked at t
Comparative study of numerical methods used in prediction of post-crack behavior of waffle slabs
One effective way to reduce dead and earthquake loads is to use waffle slabs. The use of waffle slabs leads to smaller sections. There are various methods for predicting the behavior of slabs, the most important of which is fracture mechanics. Considering the variety of geometry
New Early Warning Indicator Based on Vehicle Load and Difference Cur- vature for Simply-Supported Beam Bridges
A new indicator called Vehicle Load Difference Curvature Indicator (VLDCI) was proposed in this paper to further study the application of difference curvature to early warning of simply supported beams. Values of VLDCI can be obtained based on the measured vertical displacement d
Factors associated with HIV RNA viral loads in ART-naïve patients: implications for treatment as prevention in concentrated epidemics
BACKGROUND Limited data are available on factors associated with HIV-RNA viral load (VL) among antiretroviral treatment (ART)-naïve key populations in concentrated epidemics. METHODS We conducted a cross-sectional survey of 1211 adult ART-naïve patients at 19 HIV clinics in Ho Ch
Visualisation of a Simple Beam under a Load in Virtual Environment
Visualisation is generally considered to be a problem in structural design. Being an iterative process, structural design is time consuming for engineers, and results are difficult for clients to visualize. Current numerical methods have slow dynamic visualisation capability, whi
