A single bottle blood culture system (Oxoid Signal system) was compared with a conventional two bottle subculturing system. A total of 2016 routine blood samples yielded 186 (9%) clinically important isolates. Of these, 40 (21%) were isolated only in the Oxoid system and 30 (17%) only in the conventional system. One hundred and sixteen (62%) were isolated from both systems. Volume of blood was ...

Two-bottle tests have been used extensively to measure the preference for taste and nutrient solutions but there has been little work with tests involving more than two bottles. Here, we compare the results obtained in two-bottle tests with those obtained in three- and six-bottle tests. In Experiment 1, we measured the preferences for 2 mM saccharin, 50 mM citric acid, 0.3 mM quinine hydrochlor...

BACKGROUND In the intensive care unit we have observed that patients have different adherence to 2 commonly used positive-expiratory-pressure (PEP) therapy devices: the PEP bottle and the PEP mask. The reason for this difference is not clear. METHODS In a randomized prospective study, we made continuous recordings of airway pressure and airflow, with 20 healthy volunteers, with the PEP bottle...

In this paper, we shall determine the complete list of irreducible quadrangulations of the Klein bottle. By this result, we can easily list all the minorminimal 2-representative graphs on the Klein bottle. Moreover, we shall show that any two bipartite quadrangulations of the Klein bottle with at least 10 vertices are transformed into each other by a sequence of diagonal slides and a sequence o...

The cleanliness of feeding bottles is vital for child health (1, 2). Because of versatile, light, sturdy, reusable, and cost-efficient, plastic bottles, rather than conventional glass bottles are increasingly being utilized in the reusable feeding bottles. Although the machine cleaning of bottles in the food industry has been established (3, 4), the results may not pertain to the cleaning condu...

dinoflagellates, which he sampled with a bottle of his design, closed by a messenger sent down the wire. The bottle was suspended from the end of the wire, so only a single sample could be obtained on each cast. The next sample bottle associated with Scripps was developed by Winfred E. Allen, a student of Kofoid’s and an assistant professor at Scripps from 1919–1943 (Figure 2). Allen gathered a...
