Impact of the fermentation parameters pH and temperature on stress resilience of Lactobacillus reuteri DSM 17938

This study was undertaken to investigate the impact of culture pH (4.5–6.5) and temperature (32–37 °C) on the stress resilience of Lactobacillus reuteri DSM 17938 during freeze-drying and post freeze-drying exposure to low pH (pH 2)and bile salts. Response-surface methodology analysis revealed that freeze-drying survival rates Ncells after drying/Ncells before drying*100 were linearly related to p

Antibiotic therapy in acute pancreatitis: From global overuse to evidence based recommendations

Background: Unwarranted administration of antibiotics in acute pancreatitis presents a global challenge. The clinical reasoning behind the misuse is poorly understood. Our aim was to investigate current clinical practices and develop recommendations that guide clinicians in prescribing antibiotic treatment in acute pancreatitis. Methods: Four methods were used. 1) Systematic data collection was pe

Solar Assisted Pervaporation : A process for the concentration of fruit juices in membrane pouches with solar energy

Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on a small-scale for two main reasons. The first is that it can be unhygienic since the food is easily contaminated by pests, dust or micro

Impact of language background and school factors on core language skills

Bilingual children are at a disadvantage when compared to monolingual norms in language assessment. Monolingual assessment fails to acknowledge the asymmetrically distributed linguistic competence of bilingual children, for example, different levels of mastery of family and school related concepts in the first and second languages, respectively. Consequently, monolingual assessment results in an o

A statistical method for parameter estimation from Schroeder decay curves

The sound decay curve, measured by either the interrupted noise method or the Schroeder method, can provide relevant information pertaining to a room’s acoustical properties. However, the relevant information is not always readily extractable from the measurements. In this study, measurements of the decay curves of the historically important Vadstena Abbey church in Sweden have been obtained using

Pygmy resonances: what's in a name?

The centroid, width and percentage of energy weighted sum rule of dipole resonances can be strongly affected by dynamical fluctuations and static deformations of the nuclear surface, deformations and fluctuations which, in turn, depend on pairing, and thus on Cooper pairs. Because of angular momentum conservation, such insight is restricted, to lowest order, to fluctuations/deformations of quadrup
