The aim of this study was to show the efficacy of artificial insemination employing three different diluents (A, B and C). These diluents were : (A) Galap (IMV, France), (B) DLBR (Tris-citric-glucose), (C) MA24 (Laboratorios Ovejero, León, Spain). The inseminations were done in a commercial farm. A total of 8 million of spermatozoa per dose were inseminated. A total of 2125 artificial inseminat...

Polystyrene gels crosslinked in the presence of dilucnts have been iliatie in tinc-iiii.sli bead forni suitable for packing into chromatographic rolurnns. A series of narrow molecular weight range pol) mer fractions w&s eluted through such columns with aromatic and chlorinated solvents. EfHuent concentrations were detected and recorded by a continuous differential refractoineter. The fractions ...

Nine chemically defined inoculation diluents, with compositions ranging from 0.85% NaCl to 35% marine salts, were used to evaluate the influence of diluent composition on the biochemical profiles of 30 marine and estuarine bacterial strains, including species of Vibrio, Aeromonas, Allomonas, and Photobacterium. Results demonstrated that a 20% marine salts diluent enabled the characterization of...

The aim of the present study was to investigate the composition of heroin, amphetamine, and cocaine seized in the police district of Aarhus, the second largest city in Denmark, during a 2-year period. The purity of the active substance was measured together with the frequency and purity of adulterants and diluents present in the drugs. Results are compared with a similar study conducted ten yea...

At the present time very little information is available about the survival of typhus rickettsiae in fluid media. Data on this point are of value, however, in the solution of a number of problems which arise. The data presented in this report were not collected with the idea of making a detailed investigation of various media but simply to assess the value of media in common use for work in exp...
