Micro-organismes et matiere organique du sol (modele MOMOS): bilan de 20 ans de modelisation basée sur le tracage isotopique in situModelling Organic transformations by Micro-Organisms of Soils (MOMOS model): result of 20 years of modelling based on in situ isotopic tracers
(Etude et Gestion des Sols 16(2): 113-132Francia, 2014)
Determination of velocity and direction of ground water flow in san andres island by means of radiotracers
(Departamento de Geociencias, 1975)
The injection of radiotracers in 10 boreholes in San Andres island allowed the determination of direction and velocity of ground water flow. The basis of the technique relates to the application of a relationship existing ...
Calcium alginate beads motion in a foaming three-phase bubble column
(Elsevier Science Sa, 2017-05)
Calcium alginate beads are frequently used to immobilize enzymes or microorganisms for fermentations carried out in agitated or pneumatic reactors. In this work, the well-known Radioactive Particle Tracking (RPT) technique ...
Visualization of the flow arund a bubble moving in a low viscosity liquid
(Revista Mexicana de Física, 2009)
Grazing intensity and stocking methods on animal production and methane emission by grazing sheep: Implications for integrated crop livestock system
(Elsevier, 2014-03)
Among the various sources with a potential negative impact on the environment, methane (CH4) emissions from livestock origin have been highlighted as important for the agricultural sector. Research to mitigate CH4 emissions ...
Solid motion in a three-phase bubble column examined with Radioactive Particle Tracking
(Elsevier, 2018-08)
Radioactive Particle Tracking (RPT) is a powerful advanced technique for studying the solid motion within industrial scale multiphase reactors. However, it is rather difficult to implement in actual industrial installations, ...
A light in the shadow: the use of Lucifer Yellow technique to demonstrate nectar reabsorption
(2013)
Abstract Background Nectar reabsorption is a widely known phenomenon, related to the strategy of resource-recovery and also to maintain the nectar homeostasis at the nectary. The method currently performed to demonstrate ...
Magnetic images of the disintegration process of tablets in the human stomach by ac biosusceptometry
(Iop Publishing Ltd, 2005-12-07)
Oral administration of solid dosage forms is usually preferred in drug therapy. Conventional imaging methods are essential tools to investigate the in vivo performance of these formulations. The non-invasive technique of ...
Characterisation and origins of melanin-concentrating hormone immunoreactive fibres of the posterior lobe of the pituitary and median eminence during lactation in the Long-Evans rat
(2019-01-01)
Although the melanin-concentrating hormone (MCH) and its coding mRNA are predominantly found in the tuberal hypothalamus, there is detectable synthesis of MCH in the preoptic hypothalamus exclusively in lactating dams, ...
