Le gaz carbonique des vins. I - Dosage à l'aide d'une électrode spécifique. Comparaison avec les méthodes traditionnelles

open access: yesOENO One, 1976
Une nouvelle méthode pour la détermination de la concentration en C02 des vins est décrite ; elle met en oeuvre une électrode spécifique de mesure des pressions partielles du gaz dissous.

Effects of Elevated CO2 Concentration on Photosynthetic Carbon Metabolism in Flag-Leaf Blades of Rice before and after Heading

open access: yesPlant Production Science, 2003
We monitored the effects of elevated atmospheric C02 concentrations on the photosynthetic carbon metabolism in the flag leaves of rice plant (Oryza sativaL. cv. Akitakomachi) before and after heading.

Benefits of urban greenery: a case study for Buenos Aires city

open access: yesHeringeriana, 2014
Although in Buenos Aires urban trees are  very much appreciated and it is widely acknowledged  that they perform an important function in the city  environment, there are no empirical studies about  their role as both carbon di oxide sinks and ...

Evidence of spin disorder at the surface–core interface of oxygen passivated Fe nanoparticles [PDF]

open access: yes, 1998
Hysteresis, thermal dependence of magnetization, and coercivity of oxide coated ultrafine Fe particles prepared by inert gas condensation and oxygen passivation have been studied in the 5–300 K range.

A behaviour model to simulate stomatal resistance [PDF]

open access: yes, 1975
We review the properties of characters of the N=4 SCA in the context of a non-linear sigma model on $K3$, how they are used to span the orbits, and how the orbits produce topological invariants like the elliptic genus.

Changes in Photosynthetic Activity and Export of Carbon by Overexpressing a Maize Sucrose-Phosphate Synthase Gene under Elevated C02 in Transgenic Rice

open access: yesPlant Production Science, 2003
To investigate whether increased sucrose-phosphate synthase (SPS) activity alters photosynthetic activity and/or the export of carbon from leaves under elevated C02 partial pressure ([C02]), we raised two lines of transgenic rice (H54-9 and H69-7), each ...

Bidirectional Decoding for Statistical Machine Translation [PDF]

open access: yes, 2002
This paper describes the right-to-left decoding method, which translates an input string by generating in right-to-left direction. In addition, presented is the bidirectional decoding method, that can take both of the advantages of left-to-right and ...

Fast computation of trimmed means [PDF]

open access: yes, 2011
We present two methods of calculating trimmed means without sorting the data in O(n) time. The existing method implemented in major statistical packages relies on sorting, which takes O(n log n) time.

Getting Started with Particle Metropolis-Hastings for Inference in Nonlinear Dynamical Models [PDF]

open access: yes, 2019
This tutorial provides a gentle introduction to the particle Metropolis-Hastings (PMH) algorithm for parameter inference in nonlinear state-space models together with a software implementation in the statistical programming language R.
