Publikováno v: Day 2 Thu, March 16, 2017.

The importance of real-time cementing monitoring was discounted by the oil & gas industry for years, until the Deepwater Horizon accident in 2010. The subsequent updates to US federal regulation 30 CFR Part 250 (released in 2016) caused a re-evaluati

Autor: Claudio J. Bidau, E. Justo, J. R. Contreras, Esteban Braggio, Mabel D. Giménez

Publikováno v: Caryologia. 52:131-140

The central region of Argentina is occupied by a karyotypically stable group of Ctenomys species that form the "mendocinus" complex (C. australis, C. azarae, C. mendoci-nus, C. porteousi and C. chasiquensis), which contacts with populations of C. tal

Publikováno v: Journal of Aquatic Animal Health. 8:130-134

To determine the virulence of Piscirickettsia salmonis in coho salmon Oncorhynchus kisutch and rainbow trout O. mykiss, juvenile fish (16–17 g) of both species were held in freshwater and inoculated intraperitoneally (0.05 mL) with seven 10-fold se
