Un modello realistico per visualizzazioni in didattica
2019
In this work, two applications for the visualization of the aggregation and the solubilization of structureless interacting particles are presented. The applications allow to demonstrate on a qualitative basis as well as by quantitatively monitoring the time evolution of the surface/volume ratio and of the fractions of aggregated particles, that, on the one hand, the growth of nanoaggregates implies a decrease of their surface/volume ratio and, on the other, that the formation of homogeneous mixtures is the result of favorable solute-solvent interactions as well as of temperature. It is suggested that, along with the use of suitable macroscopic examples, visualizations by the present applic…
Two‐sample problems in statistical data modelling
2010
A common problem in mathematical statistics is to check whether two samples differ from each other. From modelling point of view it is possible to make a statistical test for the equality of two means or alternatively two distribution functions. The second approach allows to represent the two‐sample test graphically. This can be done by adding simultaneous confidence bands to the probability‐probability (P — P) or quantile‐quantile (Q — Q) plots. In this paper we compare empirically the accuracy of the classical two‐sample t‐test, empirical likelihood method and several bootstrap methods. For a real data example both Q — Q and P — P plots with simultaneous confidence bands have been plotted…
Fibre fragment distribution in a single-fibre composite tension test
2001
Abstract Single fibre fragmentation tests are performed for brittle fibres with Weibull strength distribution and different surface treatments. The fragmentation process is modelled and closed-form expressions for break spacing distribution are obtained. The model accounts for the effect of finite fibre length on the initial fragmentation as well as for break interaction on the advanced fragmentation stage. It is assumed that the exclusion zone due to fibre–matrix interface failure and stress recovery in the fibre is linearly dependent on the applied load. This assumption is validated experimentally. The derived theoretical average fragment length dependence on applied load is used to deter…
Occupation probabilities of single particle levels using the microscopic interacting boson model: Application to some nuclei of interest in neutrinol…
2016
We have developed a new method to calculate the occupancies of single particle levels in atomic nuclei. This method has been developed in the context of the microscopic interacting boson model, in which neutron and proton degrees of freedom are treated explicitly. The energies of the single particle levels constitute a very important input for the calculation of the occupancies in this method. In principle these energies can be considered as input parameters that can be fitted to reproduce the experimental occupancies. Instead of fitting, in this study we have extracted the single particle energies from experimental data on nuclei with a particle more or one particle less than a shell closu…
Psychotherapy Integration: A main Obstacle and Challenge
2018
Abstract Psychotherapy integration is a key trend in psychotherapy nowadays. This paper offers a critical perspective on a main obstacle and challenge for psychotherapy integration. Psychotherapy integration should be treated more as a process than as a product. For psychotherapy integration to contribute to the future of psychotherapy, it should not forget its original Exploratory spirit, avoiding and being cautious about Established approaches, and being, therefore, more a process than a product. This assumption should be related first with the core spirit of psychotherapy integration, an ongoing process of respect for different psychotherapeutic models, and an attitude of work in progres…
Zinc Adsorption by Activated Carbon Prepared from Lignocellulosic Waste Biomass
2019
Sawdust was used as a precursor for the production of biomass-based activated carbon. Carbonization and activation are single-stage processes, and steam was used as a physical activation agent at 800 °
Sintētisko miRNS ietekme uz zarnu mikrobioma kompozīciju 2. tipa cukura diabēta peļu modelī
2022
Zarnu mikrobioma kompozīcijas izmaiņas tiek asociētas ar dažādām slimībām, tostarp otrā tipa cukura diabētu (T2D). Interese par T2D ārstēšanu, regulējot mikrobiomu, ir strauji augusi. Ir pierādīts, ka miRNS spēj tieši saistīties pie baktērijām, tādējādi ietekmējot to sastopamību. Lai noskaidrotu, vai un kā miRNS ietekmē mikrobioma sastāvu un diabēta izpausmes diētas ierosinātā T2D peļu modelī, tām tika orāli nodrošināta nedēļu ilga dažādu miRNS terapija, kam sekoja fēču metagenoma sekvencēšana. Pelēm, kas saņēma paaugstināta tauku satura barību, miRNS terapijas ietekmē izmainījās zarnu mikrobioma kompozīcija. Pēc miR-141-3p terapijas atšķirīgi sastopami bija Eggerthellaceae, Clostridiales, …
