EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA); Scientific Opinion on the substantiation of a health claim related to Bifidobacterium animalis subsp. lactis LMG P-21384 and changes in bowel function (ID 2940, further assessment) pursuant to Article 13(1) of Regulation (EC) No 1924/2006

<p>Following a request from the European Commission, the Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to provide a scientific opinion on a health claim pursuant to Article 13 of Regulation (EC) No 1924/2006 in the framework of further assessment in relation to <em>Bifidobacterium animalis </em>subsp. <em>lactis </em>LMG P-21384 and changes in bowel function. The food constituent that is the subject of the health claim, <em>B. animalis </em>subsp. <em>lactis </em>LMG P-21384, is sufficiently characterised. The claimed effect, changes in bowel function such as reduced transit time, more frequent bowel movements, increased faecal bulk, or softer stools may be a beneficial physiological effect, provided that it does not result in diarrhoea. No human intervention studies were provided from which conclusions could be drawn for the scientific substantiation of the claim. On the basis of the data presented, the Panel concludes that a cause and effect relationship has not been established between the consumption of <em>B. animalis </em>subsp. <em>lactis </em>LMG P-21384 and changes in bowel function.</p&gt

Mechanical oil extraction of Nicotiana tabacum L. seeds: analysis of main extraction parameters on oil yield

The aim of this study is to find the best conditions of tobacco seed oil (TSO) press extraction, combining multiple extraction factors such as screw rotational speed, seeds preheating and extraction temperature, in order to have a higher oil yield. The extracted oil, having peculiar chemical properties, can be used for several purposes, also as edible oil. TSO was obtained using a mechanical screw press that has been assembled with a head press and with speed and temperature sensors mounted on the machine. Results show that the combination of high extraction temperature, slow rotational screw speed and seeds preheating has a significant effect on the oil yield. Extracting under such conditions, oil yield is 79.47±0.12 as % (w/w), which is 25% (w/w) more than the lowest yield among investigated condition

The Effective Theory of Quantum Black Holes

We explore the quantum nature of black holes by introducing an effective framework that takes into account deviations from the classical results. The approach is based on introducing quantum corrections to the classical Schwarzschild geometry in a way that is consistent with the physical scales of the black hole and its classical symmetries. This is achieved by organizing the quantum corrections in inverse powers of a physical distance. By solving the system in a self-consistent way we show that the derived physical quantities, such as event horizons, temperature and entropy can be expressed in a well defined expansion in the inverse powers of the black hole mass. The approach captures the general form of the quantum corrections to black hole physics without requiring to commit to a specific model of quantum gravity.Comment: Revised version, added references, refined text and added explanatory footnote. 23 pages, 13 figure
