absorption of flavor compounds from food into the package is one of the interactions which occurbetween food and packaging material. this phenomenon is of high importance, because absorptionof flavors into the packaging material could diminish the flavor intensity of the product as well asloss of mechanical/border properties of the packaging material, so the final loss of quality in thefood pro...

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...

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently completed the first phase of its low global warming potential alternative refrigerants evaluation program (Low-GWP AREP). This industry-wide cooperative research program identified and evaluated promising alternative refrigerants’ performance over the past two years. Thirty-eight low-GWP refrigerants were tested during t...

OBJECTIVES This study was performed to determine whether the combined use of one-bottle self-etch adhesives and composite resins from same manufacturers have better bond strengths than combinations of adhesive and resins from different manufacturers. MATERIALS AND METHODS 25 experimental micro-shear bond test groups were made from combinations of five dentin adhesives and five composite resin...
