Ecosystems in Action: Lessons from Marine Ecology about Recovery, Resistance, and Reversibility
sustainabilit resilience kelp forest
2015/12/11
The study of ecosystems in action, by measuring ecosystem recovery from disturbance, resistance to alterations, and the reversibility of ecosystem
changes, highlights features of natural communities ...
Quasi-Reversibility Regularization Method for Solving a Backward Heat Conduction Problem
Back Heat Conduction Ill-Posed Problem Quasi-Reversibility Regularization
2013/1/30
Non-standard backward heat conduction problem is ill-posed in the sense that the solution(if it exists) does not depend continuously on the data. In this paper, we propose a regularization strategy-qu...
A Linear Programming Approach to Weak Reversibility and Linear Conjugacy of Chemical Reaction Networks
chemical kinetics stability theory weak reversibility linear programming dynamical equivalence
2011/8/30
Abstract: A numerically effective procedure for determining weakly reversible chemical reaction networks that are linearly conjugate to a known reaction network is proposed in this paper. The method i...
Information, fidelity, and reversibility in photodetection processes
Information fidelity reversibility photodetection processes
2010/11/8
Four types of photon counters are discussed in terms of information, fidelity, and physical reversibility: conventional photon counter, quantum counter, and their quantum nondemolition (QND) versions...
A statistical test for time reversibility of stationary finite state Markov chains
Markov chain Time reversible
2010/9/17
In this paper stationary irreducible aperiodic finite state Markov chains are considered. We investigate time reversibility of these chains and a statistical tool for characterizing their time reversi...
Solute transport in fractured media–analysis of non-reversibility in tracer tests
Solute transport fractured media non-reversibility tracer tests
2009/11/2
This paper describes several small-scale (laboratory) experiments designed to simulate solute transport through fractured formations. A block of granite was broken to produce a fracture similar to tho...
The Poetry Of Reversibility And The Other In The English Patient
English Patient Reversibility poetry
2009/10/16
Those who lament the disappearance of poetry in our time would do well to look for its reappearance as cinema, for example Minghella’s The English Patient. Poetry was once a place for the “irruption o...
Reversibility of oxygen-induced injury to the alveolar epithelium: an ultrastructural study
pulmonary oxygen toxicity animal rabbit cytochrome C alveolar epithelium
2009/7/14
Continuous exposure of rabbits to 100 percent O2 at one atmosphere (1 ATA) for 48 h damages the alveolar epithelium increasing its permeability to lipid insoluble molecules. The purpose of this study ...
Reversibility in blood-brain barrier, microcirculation, and histology in rat brain after decompression
decompressio air animal rat
2009/6/8
To examine the changes in blood-brain barrier (BBB), cerebral microcirculation, and histology from 15 min to 72 h after decompression, 90 rats were exposed to experimental compression to 6 atm abs air...
Glyoxal uptake on ammonium sulphate seed aerosol: reaction products and reversibility of uptake under dark and irradiated conditions
Glyoxal ammonium sulphate seed aerosol irradiated conditions
2009/6/2
Chamber studies of glyoxal uptake onto ammonium sulphate aerosol were performed under dark and irradiated conditions to gain further insight into processes controlling glyoxal uptake onto ambient aero...
Climate change as a confounding factor in reversibility of acidification: RAIN and CLIMEX projects
acid deposition global change
2009/3/24
The RAIN and CLIMEX experiments at Risdalsheia, southernmost Norway, together cover 17 years (1984-2000) of whole-catchment manipulation of acid deposition and climate. A 1200 m2 roof placed over the ...
Modelling reversibility of central European mountain lakes from acidification: Part II – the Tatra Mountains
MAGIC atmospheric deposition sulphate
2009/3/12
A dynamic, process-based model of surface water acidification, MAGIC7, has been applied to four representative alpine lakes in the Tatra Mountains (Slovakia and Poland). The model was calibrated for a...
Modelling reversibility of Central European mountain lakes from acidification: Part I - the Bohemian forest
MAGIC atmospheric deposition N retention
2009/3/12
A dynamic, process-based acidification model, MAGIC7, has been applied to three small, strongly acidified lakes in the Bohemian Forest, the Czech Republic. The model was calibrated for a set of experi...
Reversibility of long-term effects of GnRH agonist administration on testicular histology and sperm production in the nonhuman primate
GnRH agonist LH testosterone testis morphology electron microscopy monkeys
2009/2/23
The present investigation evaluates the long-term effects of GnRH agonist treatment on testicular histology, sperm production and the subsequent recovery of these parameters. Four adult rhesus monke...
Effects of an LHRH agonist analog upon sexual function in male dogs. Suppression, reversibility, and effect of testosterone replacement
LHRH agonists D-Na!(2)6-LHRH spermatogenesis
2009/2/20
Male beagle dogs were injected once daily with 10 micrograms/kg of [6-D-(2-naphthyl)alanine]-LHRH (D-Nal(2)6-LHRH), a potent LHRH agonist, for periods up to 42 days, with recovery periods up to 172 ...
