Similar Methanogenic Shift but Divergent Syntrophic Partners in Anaerobic Digesters Exposed to Direct versus Successive Ammonium Additions.

During anaerobic digestion (AD) of protein-rich wastewater, ammonium (NH) is released by amino acid degradation. High NH concentrations disturb the AD microbiome balance, leading to process impairments. The sensitivity of the AD microbiome to NH and the inhibition threshold depend on multiple parameters, especially the previous microbial acclimation to ammonium stress.

Local-regional anesthesia in the management of stingray stings: Experience of the Bouffard medical-surgical hospital in Djibouti.

Stingray injuries are very painful. Systemic analgesics are ineffective, and the use of local-regional anesthesia has been reported. This retrospective descriptive study reviewed all cases of stingray injuries seen at the emergency department of the Bouffard Hospital (Djbouti, Africa) between 2011 and 2014.

Clinical Survey of Dengue Virus Circulation in the Republic of Djibouti between 2011 and 2014 Identifies Serotype 3 Epidemic and Recommends Clinical Diagnosis Guidelines for Resource Limited Settings.

Dengue virus is endemic globally, throughout tropical and sub-tropical regions. While the number of epidemics due to the four DENV serotypes is pronounced in East Africa, the total number of cases reported in Africa (16 million infections) remained at low levels compared to Asia (70 million infections). The French Armed forces Health Service provides epidemiological surveillance support in the Republic of Djibouti through the Bouffard Military hospital.

Integrated fixed-film activated sludge ANITA™Mox process--a new perspective for advanced nitrogen removal.

ANITA™Mox is a Veolia process using moving-bed biofilm reactor (MBBR) technology tested and validated in full-scale for energy- and cost-effective autotrophic N-removal from sidestream effluent using anammox (ANaerobic AMMonium OXidation) bacteria. In order to increase the ANITA™Mox process performances under different operating conditions (e.g.

Prediction of anaerobic biodegradability and bioaccessibility of municipal sludge by coupling sequential extractions with fluorescence spectroscopy: towards ADM1 variables characterization.

Advanced dynamic anaerobic digestion models, such as ADM1, require both detailed organic matter characterisation and intimate knowledge of the involved metabolic pathways. In the current study, a methodology for municipal sludge characterization is investigated to describe two key parameters: biodegradability and bioaccessibility of organic matter. The methodology is based on coupling sequential chemical extractions with 3D fluorescence spectroscopy.
