Spectrochemical Rubidium-Strontium Method for Geological Age Determination
1960
The age values of lepidolites from South Africa and from Varutrask as well as that of a microcline from Varutrask have been determined and are discussed in connection with determination according to the potassium-argon method, applied to the same materials A method is suggested which allows the spectrochemical determination of Rb and Sr with sufficient accuracy. The isotopic composition is determined by means of a Fabry-Perot etalon and hollow-cathode excitation, investigating the hyper-fine structure of the Sr line at 4078 A.
Numerical assessment of the thermomechanical behaviour of the DEMO Water-Cooled Lithium Lead inboard blanket equatorial module
2018
Abstract Within the framework of EUROfusion R&D activity, a research campaign has been carried out at the University of Palermo, in close cooperation with ENEA labs, in order to assess the thermo-mechanical performances of the DEMO Water-Cooled Lithium Lead (WCLL) inboard blanket equatorial module, whether properly integrated within its whole inboard segment. In particular, a detailed 3D model of this segment, including all the other modules, the back-supporting structure and the attachment system, has been considered in order to realistically simulate the boundary conditions affecting the equatorial module behaviour. The study has been focused on the investigation of the module thermo-mech…
Wartość informacji w systemie informacyjnym w ocenie jej jakości
2018
The purpose of the article is to determine to what extent and how to evaluate the value of information available in the information system when assessing its quality. Such an evaluation, especially for systems operating on the Internet, is absolutely necessary because of the constant and rapid growth of the information resources available there, bearing the unnecessary economic costs of their poor quality and related to that negative social phenomena. The quality of information is a multidimensional category and requires evaluation of great number of different attributes. Are there among conceptual models for evaluating the quality of information also such that require evaluating the value …
STeVAL : rapport om utvikling og utprøving av et konsept for studentevaluering av undervisning og læring i høyere utdanning
2003
Rutiner for systematisk studentevaluering av undervisningen i høyere utdanning er noe som i følge den nye kvalitetsreformen vil få større plass på universiteter og høgskoler fra og med studieåret 2003. Mange av disse institusjonene har erfaringer med å la studentene foreta en slik evaluering av undervisningen midtveis eller på slutten av et semester eller studieår. Men et system for studentenes daglige tilbakemeldinger på undervisningen, og sitt eget læringsutbytte av denne, er det grunn til å tro er både lite anvendt og systematisert. Denne rapporten, og pilotprosjektet den bygger på, er ett bidrag til å utvikle en slik gjennomløpende form for studentevaluering i høyere utdanning. Prosjekt…
Kollokationen in Leserbriefen der Wochenzeitschrift Die Zeit
2020
Im Rahmen der Phraseologieforschung haben Kollokationen traditionell nur wenig Beachtung gefunden. Im Gegensatz zu Idiomen sind sie in der Regel semantisch transparent und bereiten daher Fremdsprachenlernern selten rezeptive Schwierigkeiten. Bei der Textproduktion muss jedoch die Problematik der Kollokationen beachtet werden. Aus diesem Grund halten wir Kollokationen für einen wichtigen Bereich der Phraseologie. Im vorliegenden Beitrag wird die Aufmerksamkeit auf die syntaktische Struktur, den Gebrauch und die Funktion von Kollokationen in 243 Leserbriefen der Zeitschrift Die Zeit gerichtet. Nach Heranziehung zweier Kollokationswörterbücher sowie einiger anderer Quellen konnten 278 Kollokat…
Two non-zero solutions for Sturm–Liouville equations with mixed boundary conditions
2019
Abstract In this paper, we establish the existence of two non-zero solutions for a mixed boundary value problem with the Sturm–Liouville equation. The approach is based on a recent two critical point theorem.
Use of middle cerebral velocity and blood pressure for the analysis of cerebral autoregulation at various frequencies: The coherence index
1998
A common component in many protocols for the evaluation of cerebral autoregulation is the comparison of transcranial Doppler ultrasound (TCD) velocities with blood pressure recordings, in which correlations between these two signals correspond to impaired autoregulation. With long data sets and complicated paradigms, however, visual inspection alone cannot adequately distinguish random coincidence from consistent correlation in a statistically valid fashion. We suggest and illustrate the use of the coherence index for this purpose. To illustrate this technique, long-term recordings of TCD velocity and blood pressure were obtained from 6 normal subjects and using 23 data segments from 8 pati…
Determinant Factors in Purchasing Korean Skin Care Products
2020
The demand and business opportunities in the skin and facial beauty sector have increased in the last 10 yr. The beauty and personal care industry in Indonesia grows on average of 12 %, with a market value of 33 × 109. This research emphasizes the presence of the influence of attitude, subjective norm, and perceived behavioral control on the purchase intention of skincare products that are moderated by the country of origin. The data collection is conducted by distributing questionnaires to a total of 130 respondents. Data obtained through a questionnaire are then processed with Smart Partial Least Square (PLS). The results in this study prove that the attitude and perceived behavioral cont…
Values of love: two forms of infinity characteristic of human persons
2020
AbstractIn his late reflections on values and forms of life from the 1920s and 1930s, Husserl develops the concept of personal value and argues that these values open two kinds of infinities in our lives. On the one hand personal values disclose infinite emotive depths in human individuals while on the other hand they connect human individuals in continuous and progressive chains of care. In order to get at the core of the concept, I will explicate Husserl’s discussion of personal values of love by distinguishing between five related features. I demonstrate that values of love (1) are rooted in egoic depts and define who we are as persons, (2) differ from objective values in being absolute …
Gubernamentalidad neoliberal y producción de conocimiento en la universidad: genealogía de una configuración subjetiva
2016
This article claims that any questioning of the conditions related to the feasibility of critical research projects needs to be done by taking into account the process of commodification of knowledge that has developed in universities due to the incorporation of the modes of neoliberal governmentality. This is a process which redefines the value and use that we give to produced knowledge as well as the subjectivity of university collectives. The way knowledge is understood and the subjective configurations that promote instrumental ways of relating to knowledge in an individualizing and competitive environment need to be taken into account. Therefore, we consider it politically relevant to …
