ABSTRACTThe aim of this work was to study the influence of two storage temperatures (0C and 5C) and three packaging films (low density polyethylene of 60 µm thickness, medium density polyethyle of 60 µm thickness and polyvinylchloride) on the quality of fresh‐cut Romaine lettuce stored under passive modified atmosphere. Results showed that all types of packaging reduced weight loss in fresh‐cut lettuces when stored at 0 or 5C. Firmness did not significantly change in response to storage time or packaging type during storage. Ascorbic acid retention was affected by storage temperature and modified atmosphere packaging. The type of polyethylene as packaging material and the final storage time, proved to be the most significant factors as far the visual or color parameter evaluation concerns. The modified atmosphere packaging of fresh‐cut “Romaine” lettuce at low storage temperatures (0C) is highly suggested to avoid quality degradation....
Wir berichten über einen Patienten mit ausgedehnter Steinbildung in der Prostataloge 4 Jahre nach Durchführung einer transvesikalen Prostataadenomenukleation wegen einer benignen Prostatahyperplasie. Der Patient konnte erfolgreich mit einer Kombination transurethraler und perkutaner suprapubischer Techniken in einer Sitzung therapiert werden.
This paper presents the results of an analysis to forecast saturation levels for cell phones in the US and a number of European countries based on trend data from 1984 through 2004, using technology diffusion models. The authors discuss the differences among the countries and some of the contributing factors such as existing infrastructure and cultural differences. The authors conclude with some of...
