Röntgenkleinwinkelstreuung an isotaktischem und syndiotaktischem Polymethylmethacrylat in Lösung
1964
Die Form der Streukurven von gelosten Polymethylmethacrylaten (PMMA) ist eine Funktion der Taktizitat. In der Streukurve des syndiotaktischen PMMA last sich der Einflus einer Periodizitat erkennen. Eine quantitative Deutung gelingt durch Uberlagerung einer Helixstreukurve mit einer Knauelstreukurve. Dabei mus gesetzt werden H = 21 A, R = 4 A und a = 13 A (H und R sind die Identitatsperiode bzw. der Radius der Helix, a ist die Persistenzlange des Knauels.) Die Streukurve des isotaktischen PMMA zeigt nahezu den Verlauf, der fur Fadenknauel nach Kratky et al. [2–5] zu erwarten ist. Jedoch ist ein Intensitatsdefizit zu beobachten, das durch plausible Annahmen gedeutet wird. Als Persistenzlange …
Competing-risk analysis of coronavirus disease 2019 in-hospital mortality in a Northern Italian centre from SMAtteo COvid19 REgistry (SMACORE).
2021
AbstractAn accurate prediction of the clinical outcomes of European patients requiring hospitalisation for Coronavirus Disease 2019 (COVID-19) is lacking. The aim of the study is to identify predictors of in-hospital mortality and discharge in a cohort of Lombardy patients with COVID-19. All consecutive hospitalised patients from February 21st to March 30th, 2020, with confirmed COVID-19 from the IRCCS Policlinico San Matteo, Pavia, Lombardy, Italy, were included. In-hospital mortality and discharge were evaluated by competing risk analysis. The Fine and Gray model was fitted in order to estimate the effect of covariates on the cumulative incidence functions (CIFs) for in-hospital mortality…
Pulsed electric field (PEF) as an efficient technology for food additives and nutraceuticals development
2020
Abstract The use of pulsed electric field (PEF) technology has been extensively investigated in the area of food pasteurization and gene transfection. In the recent years the technology has also shown promising application in the development of various plant- and microorganism-based added-value compounds. The main working principle of PEF is electroporation or electropermeabilization of cell membranes. The pretreatment of biological tissues with PEF improves mass transfer during solvent extraction of metabolites and thereby increases the extraction efficiency. Moreover, the application of PEF at lower intensity has shown to induce stress on the biological tissues that in turn improves the a…
Specific intensity for peaking: Is race pace the best option?
2015
Background: The peaking period for endurance competition is characterized for a relative increase of the intensity of training, after a longer period of training relatively dominated by lower intensity and higher volume Objectives: The present study was designed to compare physiological and 10 km performance effects of high intensity training (HIT) versus race pace interval training (RP) during peaking for competition in well-trained runners. Patients and Methods: 13 athletes took part in the study, they were divided into two groups: HIT and RP. HIT performed short intervals at ~105% of the maximal aerobic velocity (MAV), while RP trained longer intervals at a speed of ~90% of the MAV (a sp…
