Opis:
An implemented impedance measuring instrument is described in this paper. The device uses a dsPIC (Digital Signal Peripheral Interface Controller) as a processing unit, and a DDS (Direct Digital Synthesizer) to stimulate the measurement circuit composed by the reference impedance and the unknown impedance. The voltages across the impedances are amplified by programmable gain instrumentation amplifiers and then digitized by analog to digital converters. The impedance is measured by applying a seven-parameter sine-fitting algorithm to estimate the sine signal parameters. The dsPIC communicates through RS-232 or USB with a computer, where the measurement results can be analyzed. The device also has an LCD to display the measurement results.

Opis:
Among all the different types of penalties that exist in the various juridical systems around the world, capital punishment, also known as the death penalty, is one of the most controversial ones. The discussion about its legitimacy and legality crosses social, philosophical, cultural, religious and historical fields. The present article aims to first analyze how capital punishment is treated in different parts of the world, whether it is present or not, and to later on focus on the attempts to justify such a harsh punishment, by both the retributive and utilitarian theories of punishment.

Opis:
In this work, the influence of both characteristics of the lens and misalignment of the incident beams on roughness measurement is presented. To investigate how the focal length and diameter affect the degree of correlation between the speckle patterns, a set of experiments with different lenses is performed. On the other hand, the roughness when the beams separated by an amount are non-coincident at the same point on the sample is measured. To conclude the study, the uncertainty of the method is calculated.

Opis:
The aim of this text is to carry out an analysis of a specific picturebook type that includes two parallel narratives and can be read in two different directions. The first book under analysis, As duas estradas (2009) [Two Roads] (text by Isabel Minhós Martins), is organised using two verbal and visual narratives which tell the story of two partially simultaneous journeys in Portugal, from Lisbon to Alcobia doTejo, in two different cars by members of the same family. The second book, Olhe, por favor, não viu uma luzinha a piscar?/Corre, coelhinho, corre! (2013)[Follow the Firefly / Run, Rabbit, Run!], is a wordless picturebook that can be read in two directions, from left to right and from right to left, depicting two different visual narratives that take place in the same scenario, with different characters and specific plots. Highlighting the hybrid, multimodal and chamaeleon-like nature of the picturebook, our objective is to provide an opportunity to reflect upon this format of contemporary literature, which is in constant development and which allows increasingly more elaborate experimentation in order to stress the ludic or playful nature of picturebooks.

Opis:
The popular pharmaceutical base used in pharmacy – vaselinum flavum – was studied by an X-band (9.3 GHz) EPR spectrometer in the range of microwave power of 2.2–70 mW. The samples were sterilized in hot air oven at temperatures: 160°C (120 min), 170°C (60 min), and 180°C (30 min). The aim of this work was to determine properties and free radical concentrations in vaselinum flavum thermally sterilized at different conditions. The changes in free radical system in vaselinum flavum during storage were analyzed. Free radicals were found in all the heated samples. The lowest free radical concentration was obtained for vaselinum flavum heated at 180°C for 30 min; so these parameters are proposed for the thermal sterilization of this pharmaceutical base. Interactions with oxygen decreased free radical concentration in vaselinum flavum during storage. Strong quenching of free radicals in vaselinum flavum was observed after 2 days for the samples sterilized at temperatures 160 and 180°C. Such an effect for vaselinum flavum heated at temperature 170°C was observed later, 13 days after sterilization. Fast spin-lattice relaxation processes exist in thermally sterilized vaselinum flavum. The EPR lines of heated vaselinum flavum were homogeneously broadened. EPR spectroscopy and its use for examining the thermal sterilization process in pharmacy was confirmed.
