Food waste co-digestion with slaughterhouse waste and sewage sludge: Digestate conditioning and supernatant quality.

In this study, the anaerobic mesophilic co-digestion of food waste (FW) with municipal sewage sludge (MSS) and slaughterhouse waste (SHW) was undertaken in 3-dm laboratory reactors as well as in 50-dm reactors operated in semi-continuous conditions. The highest methane yield of around 0.63 m CH/kgVS was achieved for the mixture of FW and SHW treated in the laboratory digester operated at solids retention time (SRT) of 30 days, whereas the co-digestion of FW with MSS under similar operating conditions produced 0.

Co-digestion of pig slaughterhouse waste with sewage sludge.

Slaughterhouse wastes (SHW) are potentially very attractive substrates for biogas production. However, mono-digestion of these wastes creates great technological problems associated with the inhibitory effects of ammonia and fatty acids on methanogens as well as with the foaming in the digesters. In the following study, the co-digestion of slaughterhouse wastes with sewage sludge (SS) was undertaken.

European field study of the efficacy and safety of the novel anthelmintic monepantel in sheep.

During 2007, a large-scale controlled, multicentre, blinded and randomised field study was conducted in Scotland, England and France to assess the efficacy and safety of monepantel, the first molecule to be developed from the recently discovered amino-acetonitrile derivatives class of anthelmintics, in sheep. Monepantel was administered orally, at a minimum dose of 2.5 mg/kg bodyweight, for the control of gastrointestinal nematodes in sheep maintained at pasture in a range of commercial production systems.

[Economic aspects in selection of treatment method for tibial and femoral shaft fractures].

The aim of the study was the analysis of the costs of the treatment the patients with tibial and femur shaft fractures treated operatively and conservatively. There were 643 adults and among them 145 patients with femur shaft fractures treated by intramedullary nailing using open Küntscher method (48 patients), closed Küntscher method (35 patients), plating (35 patients) and conservatively (19 patients). There were also 498 patients with tibial shaft fractures treated by intramedullary nailing using closed Küntscher method (105 patients), plating (109 patients), screws (82 patients) and conservatively (202 patients).

[Modified surgical technique for treating hepatic echinococcosis].

The authors present modified operational technique in hepatic echinococcosis. Echinococcus in 14 patients was removed by either peri-cystic excision or hepatic lobe excision with the closure of blood inflow into the liver by construction the blood vessels in hepato-duodenal ligament for 20 minutes. All patients survived.
