The effect of the addition of pineapple residue (Ananas comosus L.) on texture, physicochemical properties, and sensory acceptability of the plant-based minced meatball
(2023-05-14)
This study aims to develop plant-based meat alternatives with unique textures by adding pineapple residue at four different ratios (0, 5, 10, 15, and 20% w/w). The developed products' textures, sensory characteristics, nutritional values, and consumer acceptance were all assessed. The results showed that an increase in the pineapple residue content caused lightness (L*), redness (a*), as well as yellowness (b*) to increase. The textural properties of the plant-based minced meatballs in this study were relatively lower ...

Studiensituation und Studienabbruchsneigung in Corona-Zeiten. Ergebnisse einer lehramtsstudentischen Online-Reflexion
(2023-06)
In diesem Beitrag wird in den Blick genommen, wie Lehramtsstudierende der Universität Kassel ihre Studiensituation in den Jahren 2021-2023 einschätzen. Der Fokus liegt dabei einerseits auf ihrer Wahrnehmung der Studienbedingungen an der Hochschule sowie anderseits ihren Beziehungen zu anderen Hochschulangehörigen. Beide Bereiche sind wesentlich für Studienzufriedenheit, zeigten sich durch die Covid-19-Pandemie stark verändert und erhöhen bei einer negativen Wahrnehmung das Risiko eines Studienabbruchs. Die empirischen ...

The Manufacture of Hot-Compacted Layered Composite Systems Made of Oriented Semifinished PP-Films
(2014-03-04)
Monoaxial stretched PP-films are used for the manufacture of hot-compacted layered composites. These are layered with stretched co-extruded coupling agent films, and are consolidated to laminates by means of a hot-compaction process, which employs pressure and temperature. This paper aims to examine the influence of the process settings on the properties of the composites during the hot-compaction process. For this purpose, the mechanical values will be determined by means of tensile testing variously compacted and ...

Volume isotope shifts in low lying transitions of Au I
(1984)
Electronic factors in the volume isotope shift have been calculated in an ab initio way with the relativistic Dirac-Fock method for a number of different optical single/and two-photon transitions in Au I. The agreement with a semi-empirical method is within 10% for the resonance transition. For this one and a few other transitions the effect of core excitation has been analyzed with the Multi-configuration Dirac-Fock method as well, and it was found to reduce the electronic factor in the order of 5 %.

Contribution of the exact Breit operator plus the electron state-dependent screening to the multiplet and fine structure of muon-electron atoms
(1980)
We investigate for very general cases the multiplet and fine structure splitting of muonelectron atoms arising from the coupling of the electron and muon angular momenta,including the effect of the Breit operator plus the electron state-dependent screening. Although many conditions have to be fulfilled simultaneously to observe these effeets, it should be possible to measure them in the 6h- 5g muonic transition in the Sn region.

Shifts of electronic KX-rays in muonic atoms
(1982)
Energies of electronic K X-rays in muonic atoms were calculated for muons in various outer orbitals and for different numbers of electrons. Energy shifts were obtained with respect to characteristic X-rays belonging to nuclear charge (Z - 1) and their possible observation is discussed. The shifts in muonic Sn as an example amount to 19, 37, and 59 eV for the muon in 5g, 6h, and 7i states respectively. However, shifts due to the number of electrons present and the electron vacancy distribution in the L-shell are ...

Organisationsberatung als lebendige Ethnopsychoanalyse
(2001)
Es soll im Folgenden nicht darum gehen, eine neue Methode zu kreieren, eine Bindestrich-Methode wie etwa "psychoanalytische Organisationsberatung" oder dergleichen. Vielmehr gehen wir davon aus, dass jeder Berater, der als Externer mit einer Organisation in Kontakt kommt auf Neues und damit Unbekanntes stößt. Wir machen dabei immer wieder die schmerzhafte Erfahrung, nicht zu durchschauen, nicht zu wissen, d.h. unsicher zu sein über die eigene Rolle und Identität. Die Realität von Institutionen erleben wir als ...

Relativistic atomic level calculations with nuclei carrying additional fractional charges
(1983)
One-electron energy levels and wavelengths have been calculated for Na-like ions whose nuclei carry quarks with additional charges ±e/3, ±2e/3. The calculations are based on relativistic self-consistent field procedures. The deviations from experimental values exhibit regularities which allow an extrapolation for the wavelengths of 3s - 3p, 3s - 4p, 3p - 3d, and 3p - 4s transitions for the nuclear charge Z = 11± 1/3, ±2/3. A number of transitions are found in the region of visible light which could be used in an ...

Estimation of the ground state correlation energy for isoelectronic series of 2 to 20 electrons
(1987)
Correlation energies for all isoelectronic sequences of 2 to 20 electrons and Z = 2 to 25 are obtained by taking differences between theoretical total energies of Dirac-Fock calculations and experimental total energies. These are pure relativistic correlation energies because relativistic and QED effects are already taken care of. The theoretical as well as the experimental values are analysed critically in order to get values as accurate as possible. The correlation energies obtained show an essentially consistent ...

Strategies towards evaluation beyond scientific impact
(Librello, 2015)
Various research fields, like organic agricultural research, are dedicated to solving real-world problems and contributing to sustainable development. Therefore, systems research and the application of interdisciplinary and transdisciplinary approaches are increasingly endorsed. However, research performance depends not only on self-conception, but also on framework conditions of the scientific system, which are not always of benefit to such research fields. Recently, science and its framework conditions have been ...
