The identification and characterization of barriers to river continuity are essential for the preparation an inventory hydraulic infrastructure. To this end, it is necessary define main identifying characterizing elements infrastructures descriptors ecological continuity, with information that can characterize them from point view their impact on watercourse. Several authors have defined decisi...

In recent years, a number of studies have revealed that cognitive control is strongly context-dependent (e.g., Crump et al., 2006). Inspired by this, computational models have been formulated based on the idea that cognitive control processes are based on associative learning (Blais et al., 2007; Verguts & Notebaert, 2008). Here, we test a natural consequence of this idea, namely, that sequenti...

Salmonella spp. are considered to be one of the most common causes of food borne bacterial infections.

In Germany 31.185 Salmonella infections were reported to the Robert KochInstitute in 2009. Since the aetiology of enteric infections in many cases is not established and ...

Enteric fever is a systemic infection caused by Salmonella serotypes; S. typhi, S. paratyphi A, S. paratyphi B, S. paratyphi Cand S. sendai (Mandell GL et al, Parker MT). It is characterized by malaise, fever, abdominal discomfort, transient rash, splenomegaly, hepatomegaly, bradycardia, and leucopenia.

Abstract Climate change has caused the inefficient operation of a significant number old weirs to pass large discharges. Therefore, this study aims increase discharge capacity labyrinth weir. A new approach was proposed by modifying weir structure. The data obtained from quarter-round crest and different sidewall angles ranging 8 35°. conventional used for comparison. results showed that percen...
