    Antibiotic treatment of patients with term premature rupture of membranes
    (1998) Ovalle, A; Gómez, R; Martinez, MA; Giglio, MS; Bianchi, R; Diaz, L; Sáez, J; Poblete, JP; Romero, R
    Background/objective Subclinical microbial invasion of the amniotic cavity in patients with premature rupture of membranes (PROM) at term occurs in 34% of cases and is a risk factor for puerperal endometritis. This study was conducted to determine whether antibiotic administration to women with PROM at term could reduce the rate of infection-related morbidity.

    Volumetric procedure to assess infiltration kinetics and porosity of fruits by applying a vacuum pulse
    (ELSEVIER SCI LTD, 1998) del Valle, JM; Aranguiz, V; Diaz, L
    In this work an improved 'volumetric' procedure was developed to assess fruit porosity using a hydrodynamic mechanism, to replace the 'gravimetric' alternative proposed by Fito in 1994 This procedure also facilitated study of the kinetics of liquid infiltration in fruit pieces as a result of the application of a vacuum pulse. It was observed that apparent porosity increased as the absolute pressure of the vacuum pulse decreased, probably as a result of tissue damage or deformation-relaxation phenomena. In the case of apples, porosity increased from an initial value of about 0.20 to about 0.30, and this increase took place in a relatively short period (about 1 min after vacuum rupture). These values did not appear to be significantly (P < 0.01) affected by either apple variety (Granny Smith or Starking Delicious) or sucrose concentration (0 or 16% w/w) in the infiltrated solution, but increased during ambient storage. Porosity values for bananas and peaches are also reported. (C) 1998 Elsevier Science Limited. All rights reserved.
