β-Relaxation and low-temperature specific heat in (KBr)1?x(KCN)x
1990
The specific heat in (KBr)1−x(KCN)x has been measured for concentrations 0.00≦x≦0.93 and for temperatures 2 K≦T≦50 K. In addition, the dipolar relaxation phenomena were studied using dielectric spectroscopy. The relaxation behaviour was parametrized assuming a Gaussian distribution of energy barriers and the mean activation energies, the distribution widths, and the attempt frequencies have been determined as a function of the CN− concentration. With these parameters the linear and the excess specific heat contributions were calculated and compared to the calorimetric results.
Equilibrium swelling and solvation studies on crosslinked polyacrylamides
2004
Polyacrylamide (PA) crosslinked with four different crosslinking agents, triethyleneglycol dimethacrylate (TEGDMA), N,N′-methylene bisacrylamide (NNMBA), hexanediol dimethacrylate (HDDMA) and divinylbenzene (DVB), with mole percents ranging from 5 to 20, was prepared by solution polymerization and subjected to swelling and solvation studies. Solubility parameters and cohesive energy density were determined from swelling studies. Molecular weight between crosslinks for these systems were determined by Flory–Rehner analysis. There is a discontinuous volume change for 10% NNMBA and HDDMA crosslinked PA, 15% TEGDMA crosslinked PA and 10 and 15% DVB crosslinked PA in solvent mixtures of acetic a…

In order to investigate the influences of different end-groups on oligomer miscibility with other substances, oligo(propylene glycol)s bearing OH groups (OPG-OH) studied in the previous paper2, were acetylated at both ends (OPG-AC). The limits of miscibility of OPG-AC with oligo(dimethylsiloxane) (ODMS) were measured turbidimetrically. A simple and reliable method for the determination of the critical points from turbidity data is presented. The observed upper critical temperatures (Tc) increase with degree of oligomerization of ODMS (ranging from 1 to 5), whereas Tc shows a minimum when the degree of oligomerization of the OPG-AC is raised (from 1 to 57,5). For lower mol. wt. oligoglycols,…
A Functional Analysis of the Finnish 2012 Presidential Elections
2016
This study applied the functional theory of political campaign discourse, developed for political campaigns in the United States to two televised presidential debates in the 2012 presidential elections in Finland. Acclaims were the most preferred statement by the candidates, with agreements being the least preferred. Policy was discussed more than character during the debates. General goals and ideals were used more frequently to acclaim than to attack. Results are generally consistent with the results of previous studies of presidential elections in the US and other countries. However, differences did emerge: the classical functional categories were supplemented by a new category, the role…

A real-space approach to the analysis of stacking faults in close-packed metals: Modelling and Q-space feedback Longo Alessandro
2020
An R-space approach to the simulation and fitting of a structural model to the experimental pair distribution function is described, to investigate the structural disorder (distance distribution and stacking faults) in close-packed metals. This is carried out by transferring the Debye function analysis into R space and simulating the low-angle and high-angle truncation for the evaluation of the relevant Fourier transform. The strengths and weaknesses of the R-space approach with respect to the usual Q-space approach are discussed.

Imatge percebuda i imatge mental
2012
S'estudia el contrast entre el que es diu la posición Lockeana i la posición Berkeleyana sobre l'origen de la cognoció. La diferencia entre elles rau en el paper asignat al llenguatje respecte al coneixement. Aquest treball manté, no obstant, una posició híbrida. Se estudia el contraste entre lo que se ha venido a llamar posición Lokeana y la posición Berkeleyana, respecto del origen de la cognición. La diferencia entre las dos está en su diferente posición acerca del papel asignado al lenguaje para el conocimiento. Este trabajo explicará la posibilidad de una posición híbrida.
A Non-Local Mode-I Cohesive Model for Ascending Thoracic Aorta Dissections (ATAD)
2018
This paper presents a non-local interface mechanical model to describe aortic dissection. In this regard, the mode-I debonding problem based on a cohesive zone modeling is endowed with non-local terms to include long-range interactions that are present in multi-layered biological tissue. Such non-local effects are related to the collagen fibers that transmit forces between non-adjacent elements. Numerical simulations are provided with different values of the non-local parameters in order to show the effect of the non-locality during the debonding processes.
The Participation of Families in the Analysis and Transformation of their Reality through a Family Debate about Values and Living Together
2015
Este estudio aborda la socialización en valores y convivencia a partir de una investigación acción que parte de un enfoque participativo y dialéctico y que utiliza el Debate familiar, una herramienta innovadora cuyas finalidades son favorecer la reflexión y el diálogo intrafamiliar e implicar a las familias en el análisis y transformación de su realidad. Esta estrategia estimula el debate e invita a pensar sobre los valores presentes en la familia, recoge información de los diferentes miembros de la unidad familiar y a su vez, sensibiliza sobre los temas tratados. Un total de 492 familias, con al menos un hijo o hija entre 7 y 16 años, participaron en este estudio. Los resultados ponen de r…
