This study shows that functional grouping of the species based on nitrogen fixing ability along with initial leaf litter C/P, C/N, P and N could help us predicting leaf litter decomposition rate. Grouping species into functional groups is a good approach to understanding exotic plants impacts on ecosystem functioning in their new environment. One key plant(More)
One hundred and seven patients aged from nine months to eight years old have been studied to evaluate the diagnosis of broncho-pulmonary recurrent infection with a preliminary studies and an association of bronchoscopy and bronchography. The first step cheek-in revealed sixty-seven diagnosis, while the bronchoscopy, the bronchography and the IgG subclasses(More)
The effect of soil, sowing depth and sowing date on growth and survival of Pistacia atlantica seedlings was evaluated in nursery conditions. Pistacia atlantica is a deciduous tree species that belongs to the Anacardiaceae family. It is valuable in soil conservation and so suitable for plantation in dry lands. Regeneration of Pistacia atlantica in western(More)
Wandering spleen (W.S) seems tu result from an abnormal development or the ligamentous attachments of this organ. The age of apparition is between 3 months and eight years. We report the youngest case of the literature of torsion of wandering spleen at two days of birth where the clinical examination and the abdominal sonography make the diagnosis.
Soil macrofauna play major roles in ecosystem functioning; however the ecological effects of macrofauna are influenced by their spatial distribution. Close relationships to soil properties are one major factor for determining spatial pattern of macrofauna. Information about macrofauna distribution pattern is scarce especially at regional scales. The limited(More)
