Suggestion for a New Type of Tube for Bacteriological Cultures
نویسنده
چکیده
1 bacteriological laboratory and from this short experience, I consider there is scope for a further lrnprovement in this type of container. The usual ' flat' is made up of an oblong ^?dy and a narrow neck with the threads for fitting the metal cap. The disadvantages in this form of 1 flatto my mind, are that the rieck is a little too narrow for utilizing the whole of the culturable surface when a loop spreader is used. This means a waste of a part ?f the medium. I believe, a larger bore of the ^eck would overcome this defect. Again, the corners of the oblong medical ' flat' being as they are abruptly angular prevent a good visibility ?f certain parts of the culture. This can be got over possibly by converting the angularities into gradual curvatures on opposite sides of the ^ain flat surfaces. This idea occurred to me

The eggshells were accurately disinfected and the embryos were removed and placed in a sterile plate. The surface of each embryo was swabbed with a sterile swab which was also plunged throug...
متن کاملNew geometry for TCP: severe plastic deformation of tubes
Since tubes are widely used for different industrial applications, processing of tubes by the Severe Plastic Deformation (SPD) method has been the target of different attempts. Among these attempts, development of SPD processes for tubes based on Equal Channel Angular Pressing (ECAP) has been more successful. As an illustration, Tube Channel Pressing (TCP) has been presented as an attractive SP...

In order to investigate the prevalence of Mannheimia haemolytica infection in cattle, nasal andnasopharyngeal swabs and blood samples were obtained from 250 cattle after slaughter at Ahvaz(southwestern Iran) abattoir. Nasal and nasopharyngeal swabs were cultured on blood agar and incubated at37°C for 24-48 h. The suspected bacterial cultures were processed for isolation of M. haemolytica follow...
