Biomass burning has only recently been recognized as a major source of important trace gases and aerosol particles. Through burning, the chemical elements in vegetation are cycled back to the atmosphere and to soils in chemical and physical forms and proportions which make biomass burning an important biogeochemical process. Before the advent of humans, fire was ignited naturally by lightning strikes in dry vegetated regions. Today, however, the process is driven almost exclusively by human activity which includes the burning of forested areas to facilitate land clearing, the burning of harvest debris to maintain cleared land, the extensive burning of natural grasslands and savannas to sustain nomadic agriculture, and the burning of biomass as fuel for cooking and heating. The importance of biomass burning is well recognized in International Global Atmospheric Chemistry and this activity, Biomass Burning Experiment :Impact on the Atmosphere and Biosphere(BIBEX), was established to address this phenomenon. It is being carried out by a multi-national science team at the Max Planck Institute for Chemistry, Germany.  3, record 1, English, - Biomass%20Burning%20Experiment%3A%20Impact%20on%20the%20Atmosphere%20and%20Biosphere

A team ran a series of computer simulations of stratospheric chemistry using standard homogeneous reactions, and found very little impact of trace gases produced by human activities. But when they adjusted the model to take account of non-standard chemistry, it responded by indicating a 16 percent drop in ozone concentrations by the year 2060.  3, record 2, English, - homogeneous%20chemical%20reaction

Photon excitation : X-ray emission induced by the impact of charged particles other than electrons, for example alpha particles, was discovered by Chadwick in 1912. High energy(1. 5 MeV) photons are associated with large cross-sections for ionization and very low backgrounds, two ideal conditions for very low detection limits that effectively reach 10[ upperscript-11]-10[ upperscript-12](g) for elements with Z > 15. On account of this high absolute sensitivity, photon excitation is used with Si(Li) detectors in many applications dealing with the simultaneous determination of trace elements in water, serum, blood and tissues.  1, record 3, English, - photon%20excitation

La thérapeutique photo-dynamique dans le cancer bronchique précoce. [...] Sous l'action d'une lumière adaptée à la molécule, ce photo-sensibilisateur devient actif et toxique. L'excitation photonique permet de transférer l'énergie vers l'oxygène ambiant qui prend alors la forme d'oxygène singulé. Cet oxygène est extrêmement réactif et toxique et oxyde tous les constituants tissulaires situés à son contact.  3, record 3, French, - excitation%20photonique

Le camping écologique repose sur les mesures suivantes : se servir d'un réchaud portatif plutôt que de faire un feu de camp; si on doit allumer un feu, le faire sur du sable ou du gravier, dans un secteur dénué de végétation, et démonter le foyer en toute sécurité avant de partir; monter sa tente dans un endroit dénué de végétation; ne pas couper de végétation pour aménager un abri; jeter l'eau de vaisselle (après en avoir filtré les restes de nourriture) dans le sol, loin des plans d'eau; faire ses besoins à l'écart, loin des sentiers et des points d'eau, enfouir les excréments et, si possible, brûler le papier hygiénique avant de couvrir le trou avec de la terre; éviter de marcher dans des endroits fragiles; nettoyer les lieux avant de quitter, en remportant tout ce qu'on y avait apporté.  3, record 4, French, - camping%20%C3%A9cologique

In the early 1900s, popular thinking among farmers had led to rejection of the portion of Jeffersonian thought that held individualism to be supreme. Politically, this led to establishment of organizations, such as the Grange. Farmers felt that they should develop and share technological knowledge among themselves. There were two sources of that knowledge. The "systematic agriculturists" looked to the emerging industry as their model. The second group, the "scientific agriculturists", looked to nature as their model, with the objective of rationalizing and formalizing their experiences as "natural historians"(Marcus, 1985). At the same time, land-grant scientists were beginning to have an impact(Rossiter, 1975). It is these philosophies and to these turn-of-the-century farmer-scientist groups that we can trace the roots of much of the current debate on sustainable agriculture.  1, record 5, English, - systematic%20agriculture
