Opis:
Recent implementations of Sigma-Delta (ΣΔ) converters have achieved low cost, low power consumption, and high integration while maintaining resolution as high as in Nyquist-rate converters. However, its usage implies demodulating the source signal delivered from ΣΔ modulation to Pulse-Code Modulation (PCM) on a pre-processing stage. This work proposes an algorithm based on Discrete Cosine Transform for impulsive signal detection to be applied directly on a modulated ΣΔ bitstream, targeting to reduce computational cost in acoustic event detection applications such as gunshot recognition systems. From pre-recorded impulsive sounds in ΣΔ format, it has been shown that the new method presents a similar error rate in comparison with traditional energy-based approaches in PCM, meanwhile, it reduces significantly the number of operations per unit time.

Opis:
Thin films of hydrogenated amorphous silicon deposited on glass and crystalline silicon substrates by rf plasma enhanced chemical vapor deposition at different rf power were studied using slow positron beam and the Raman scattering spectroscopy in order to verify the influence of that deposition parameter on the film defect structure and on the degree of disorder. By positron annihilation spectroscopy, it was found that there are mainly two types of defects in the films: large vacancy clusters or voids and small vacancy type defects. By micro-Raman spectroscopy it was observed that the degree of structural disorder is lower for the film with large vacancy clusters and this finding was related to structural relaxation process. Light soaking induced changes attributed to major atomic rearrangements were also observed.

Opis:
The evolution of defect structure during isochronal annealing of water-quenched Cu-4.83 at.% In and Cu-4.94 at.% Sn alloys was studied by measuring positron lifetime and Doppler broadening of annihilation line. The behaviour of annihilation parameters in both alloys is found to be analogous. In as-quenched alloys one component of about 180 ps is detected in the lifetime spectra. It remains intact up to the annealing temperature of 450 K and is attributed to positron annihilation at quenched-in vacancies associated with alloying atoms. When going above this temperature, the short component appears in the lifetime spectra, while intensity of the long component starts to drop giving evidence to the reduction of defect concentration. This process is observed to develop up to 550 K; thereafter all annihilation parameters level off. After crossing the phase separation temperature they begin to vary again since the defect structure comes into dependence on cooling conditions. The obtained results are discussed in terms of defect structure evolution in the course of precipitate formation.

Opis:
In the present work the thermoluminescence of a lilac α-spodumene (LiAlSi$\text{}_{2}$O$\text{}_{6}$), a natural mineral from Brazil, was investigated. Toward this aim the gamma irradiation, as well as several heating processes were carried out. The sample presented a glow curve with various thermoluminescence peaks. Emission spectrum showed only one prominent band at 610 nm, which indicates the existence of only one recombination center despite the several thermoluminescence centers exhibited, due to intrinsic defects. Using correlation between thermoluminescence and optical absorption techniques we discuss the effects of gamma radiation and annealing in the lilac spodumene, and conclude that an annealing at about 230ºC can be applied to natural lilac spodumene gems used in jewelry for increment of its lilac color.

Opis:
Positron annihilation lifetime spectroscopy was used to study the free volume parameters in polypropylene oxide-based tri-isocyanate terminated prepolymer/polycaprolactone diol bi-soft urethane/urea membranes (PU/PCL) with PCL content from 5 up to 25 wt%. Positron annihilation lifetime spectroscopy measurements carried out in the temperature range 298-324 K mirrored the phase separation of the various soft and hard segments present in the membranes. The size and amount of free volume holes determined by positron annihilation lifetime spectroscopy appear to be correlated with the $CO_2$ gas permeability through the membranes.

Opis:
Paracoccidioidomycosis is a systemic mycosis caused by inhalation of the fungus P. brasiliensis. The primary infection involves the lungs and can spread to other organs and systems resulting in secondary lesions in the mucosa, lymph nodes, skin and adrenal glands. Oral lesions are insidious in progression and can be multifocal. The aim of this study was to report a case of paracoccidioidomycosis in a patient who was misdiagnosed with pulmonary tuberculosis. A 40-year-old male, HIV-positive, was admitted with complaints of weight loss, asthenia, diarrhea, coughing and dyspnea. Physical examination revealed the presence of caries, coated tongue, residual roots, oral candidiasis and ulcerated, granulomatous lesions in the hard palate and alveolar ridge. Laboratory tests revealed anemia, neutrophilia and an increased erythrocyte sedimentation rate. Cytology and incisional biopsy were performed. The cytological examination revealed the presence of fungus and the pathological examination confirmed the diagnosis of paracoccidioidomycosis. The doctors who previously made the diagnosis of tuberculosis were informed of the new diagnosis, as the patient was being treated for tuberculosis. The treatment for paracoccidioidomycosis was initiated and the patient is under clinical monitoring.
Parakokcydioidomikoza jest grzybicą układową, wywołaną przez inhalację grzyba z gatunku P. brasiliensis. Zakażenie pierwotne obejmuje płuca i może rozprzestrzeniać się do innych narządów i układów w wyniku wtórnych zmian obejmujących błony śluzowye, węzły chłonne, skórę i nadnercza. Zmiany w obrębie jamy ustnej są podstępne w progresji, wieloogniskowe i mogą dotyczyć różnych obszarów anatomicznych. Celem niniejszego badania było opisanie przypadku parakokcydioidomikozy u pacjenta, u którego błędnie rozpoznano gruźlicę płuc. Czterdziestoletni mężczyzna, murarz, zakażony wirusem HIV, został przyjęty do szpitala Oswaldo Cruz (Curitiba) z powodu zgłaszanej utraty masy ciała, osłabienia, biegunki, kaszlu i duszności. Badanie przedmiotowe wykazało obecność próchnicy, nalotu na języku, pozostałości korzeni zębów, kandydozy jamy ustnej oraz zmian owrzodzeniowych o charakterze ziarniniakowym w obrębie podniebienia twardego i wyrostka zębodołowego. Badania laboratoryjne wykazały niedokrwistość, neutrofilię i podwyższony odczyn OB (szybkość opadania krwinek czerwonych). Wykonano cytologię oraz biopsję wycinkową. Badanie cytologiczne wykazało obecność grzyba, a badanie patologiczne potwierdziło rozpoznanie parakokcydioidomikozy. Lekarze zostali poinformowani o diagnozie u pacjenta, który był leczony z powodu gruźlicy. Ustalono sposób leczenia parakokcydioidomikozy, a chory pozostaje pod kontrolą kliniczną.

Opis:
The objective of this work is to investigate the influence of slotted air gap constructive parameters on magnetic flux density of rotating machines. For this purpose, different approaches were used to solve the air gap field diagram using finite element method and the magnetic field distribution uniformity was evaluated by Carter's factor calculation on two-dimensional and three-dimensional models. Sensitivity analysis of slot constructive parameters was performed and results show that slot geometry modifies the magnetic flux on air gap and shifts the air gap magnetic equipotential midline of double slotted machines. Finally, minimization of Carter’s factor on two-dimensional model presents an optimized slot geometry with a near uniform magnetic flux density distribution.

Opis:
Positron annihilation techniques are used for the structural investigation of solids but the interpretation of results in grainy and porous media is still unclear. A unique picture can be obtained assuming that the dominant process is Ps trapping in competing "extended free volume" sites. In samples with a large amount of free volumes near-saturation Ps trapping will rule the lifetime pattern, and very long lifetimes of over 100 ns might arise from o-Ps trapped in mesopores. It is shown that lifetime parameters must be corrected for the 3γ/2γ counting efficiency ratio. The results demonstrate the high sensitivity of Ps to mesopores in zeolites but also that Ps-trapping poses limitations on the applicability of lifetime to structural investigation in porous systems. The evolution of the lifetime spectra upon changes in the sample and measuring conditions should be considered in a complex way, observing not only changes in some selected components but in the whole lifetime pattern simultaneously.

In this paper, we look at the level of customer satisfaction as well as customer services in a passenger railway station. Specifically the objective of this paper is to develop and employ a simple method for analyzing the customer satisfaction in railway stations to help us identify ways for improving both the customer service and the station design. The method developed is applied for the purposes of Newcastle Central rail station. After having studied different approaches we used a survey to collect the necessary data for analysis. A comparison of the opinions of different categories of rail station users has been undertaken. As a result different areas for improvement have been identified. This paper can be seen as a starting point for further research on a detailed customer satisfaction analysis for Newcastle Central.
In dieser Arbeit werden wir mit Blick auf die wachsende Nachfrage im Personenzugverkehr einen Bahnhof auf Kundenservice und Kundenzufriedenheit untersuchen. Das Ziel dieser Arbeit sind die Entwicklung einer vereinfachten Methode, um die Kundenzufriedenheit zu analysieren, und Optimierungspotentiale zu identifizieren. Die entwickelte Methode wird im weiteren auf die Fallstudie des Hauptbahnhofs in Newcastle upon Tyne angewandt. Nach der Verbindung und Vereinfachung verschiedener Ansätzen verwenden wir in Umfrage, um die notwendige Informationsbasis für einen Vergleich mit dem gewählten Ansatz zu gewinnen. Wir erwarten die gröβten Bereiche mit Optimierungsbedarf herauszustellen und konkrete Maβnahmen zur Verbesserung vorschlagen zu können. Diese Arbeit kann als Basis für weiterführende Forschung oder eine detailliertere Kundenumfrage am Hauptbahnhof in Newcastle upon Tyne dienen.

The wide hybridisation has been applied to cereals breeding allowing to the production of new amphiploids. Triticale (X Triticosecale Wittmack) was the first synthetic amphiploid of the Triticeae tribe and performed well in comparison with its parent’s wheat and rye. In this work we aimed to analyse the meiotic behaviour and to identify the chromosomes present in both mitotic and meiotic metaphase cells of the portuguese cultivar ‘Douro’ (2n=42, AABBRR) using in situ hybridisation technique with genomic DNA from rye and repetitive DNA sequences as probes. Triticale ‘Douro’ presented a high level of homologous pairing. The mean number of bivalents was 20.14 and the average of ring bivalents was higher than rod bivalents. The total frequency of univalents was reduced (1.72), presenting the wheat univalents a higher frequency comparatively to the rye univalents. No multivalent configurations were seen, confirming the high meiotic regularity and stability of triticale ‘Douro’. The simultaneous use of pSc119.2 and pSc250 repetitive DNA probes on mitotic and meiotic chromosomes allowed the identification of all rye chromosomes. The pSc119.2 probe identified some wheat chromosomes, namely from B genome, and the chromosome pairs 4A and 5A.

Opis:
In durum wheat × rye hybrids and the derived amphiploid triticale, AABBRR, the expression of the 1R rRNA genes is largely suppressed. Alloauto-octoploid triticales, AABBRRRR, allows the evaluation if rye NOR inactivation can be overcome by the increase of rye genome number. In the present work, we used silver staining and in situ hybridisation techniques in order to study the nucleolar activity and to localize the rRNA genes in hexaploid and alloauto-octoploid triticales. The use of rye genomic DNA as probe allowed the identification of the rye chromosomes present in both hexaploid and octoploid triticales (14 and 28, respectively). The simultaneous use of the ribosomal sequence enabled the localisation of 18S-25S rDNA on the satellite chromosomes of both triticales. On hexaploid triticale we detected six rDNA sites (four on wheat chromosome pairs 1B and 6B and two on rye chromosome pair 1R), whereas on alloauto-octoploid triticale eight rDNA sites (four on wheat-pairs 1B and 6B and four on rye chromosome pairs 1R) were observed. As expected, the maximum number of active Ag-NORs per metaphase cell was coincident with the maximum number of nucleoli per interphase nucleus confirming that all and only the NORs functionally active during interphase are stained by silver at the next mitotic metaphase. Comparison of the nucleolar activity between hexaploid and octoploid triticales analysed here indicates that the increase in 1R chromosomes from two to four does not change the suppression of rye nucleolar activity. This supports the suggestion that genomic interactions are under strong genetic control.

Opis:
Mapping and assessment of erosion risk is an important tool for planning of natural resources management, allowing researchers to propose modifi cation in land-use properly and implement more sustainable management strategies in the long-term. The Tapacurá river catchment, located in Pernambuco State, Northeastern Brazil, is one of the planning units for management of water resources of Recife Metropilitan Region (RMR), and it is divided into 12 sub-basins. The objective of this study is to evaluate the spatial variability of vegetal cover and sediment yield in this basin through remote sensing and GIS techniques. Maps of the erosivity (R), erodibility (K), topographic (LS), cover-management (C) and support practice (P) factors were derived from the digital elevation model (DEM), climate database, and soil and NDVI maps, taking into account information available in the literature. In order to validate the simulation process, Sediment Delivery Ratio (SDR) was estimated. The obtained NDVI map showed vegetation loss during the analyzed period, indicating a distinct contrast between loss and gains of vegetation index. The vegetation and sediment yield mapping showed to be a useful tool for environmental monitoring and management, which can provide satisfactory results when jointly used. The results suggest a mean SDR around 0.9 and estimate the sediment yield as 23.98 ton/ha/month.
