This paper focus on the sea wave characterization (significant wave height, peak wave period, mean wave period, mean wave direction) at the Azores archipelago and the evaluation of the wave energy source. For the sea wave characterization, the numerical mode! SWAN, is applied for a period of 10 years in several points around each of the nine islands of Azores, at the 100 m CD bathymetric. Based on those results, average wave power maps considering whole 10 year period or the winter and the summer periods are constructed. An average sea wave climate is also presented. Moreover, sea wave characterization is also made for Porto Cachorro at Pico island, where a power pIant is constructed since 1990. 243-254pp DHA/NPE

AIMS: Given the advances in atrial fibrillation (AF) management and the availability of new European Society of Cardiology (ESC) guidelines, there is a need for the systematic collection of contemporary data regarding the management and treatment of AF in ESC member countries.METHODS AND RESULTS: We conducted a registry of consecutive in- and outpatients with AF presenting to cardiologists in nine participating ESC countries. All patients with an ECG-documented diagnosis of AF confirmed in the year prior to enrolment were eligible. We enroled a total of 3119 patients from February 2012 to March 2013, with full data on clinical subtype available for 3049 patients (40.4% female; mean age 68.8 years). Common comorbidities were hypertension, coronary disease, and heart failure. Lone AF was present in only 3.9% (122 patients). Asymptomatic AF was common, particularly among those with permanent AF. Amiodarone was the most common antiarrhythmic agent used (∼20%), while beta-blockers and digoxin were the most used rate control drugs. Oral anticoagulants (OACs) were used in 80% overall, most often vitamin K antagonists (71.6%), with novel OACs being used in 8.4%. Other antithrombotics (mostly antiplatelet therapy, especially aspirin) were still used in one-third of the patients, and no antithrombotic treatment in only 4.8%. Oral anticoagulants were used in 56.4% of CHA2DS2-VASc = 0, with 26.3% having no antithrombotic therapy. A high HAS-BLED score was not used to exclude OAC use, but there was a trend towards more aspirin use in the presence of a high HAS-BLED score.CONCLUSION: The EURObservational Research Programme Atrial Fibrillation (EORP-AF) Pilot Registry has provided systematic collection of contemporary data regarding the management and treatment of AF by cardiologists in ESC member countries. Oral anticoagulant use has increased, but novel OAC use was still low. Compliance with the treatment guidelines for patients with the lowest and higher stroke risk scores remains suboptimal.

In recent years, research on the psychology of gaming has examined the negative and positive outcomes of playing video games. Thus far, a variety of affective phenomena have been investigated. In this chapter we will continue this exploration by examining the emotions elicited by the act of playing video games. Because the study of emotions must rely on different type of methods, including subjective self-reports (e.g., description of feelings), neuropsychophysiological measurements (e.g. electromyography, skin conductance, heart rate, event-related potentials, functional magnetic resonance imaging), biological markers (e.g. cortisol, testosterone) and behaviours (e.g., facial expressions), we will cover all these distinct methods. We will explore how dimensional and categorical models of emotions have been used to identify the emotional responses of players, including their enjoyment experience. Expanding upon past research findings we will also discuss the social implications of gaming and suggest areas for future research.

Um Cardioversor Desfibrilhador Implantável (CDI) destina-se a detectar arritmias ventriculares potencialmente fatais e a terminá-las, quer por estimulação ventricular rápida quer através de uma descarga eléctrica. Actualmente, é uma terapia aceite na prevenção primária e secundária da morte súbita cardíaca. A configuração típica de um CDI é de um eléctrodo de sensing e de desfibrilhação no ventrículo direito (VD) com dois coils (um distal, no ventrículo e outro próximal, na junção da veia cava superior (VCS) com a aurícula direita) que juntamente com o gerador, forma a designada “tríade ventricular”. Esta configuração embora seja eficaz na maior parte dos doentes, não é a mais racional do ponto de vista eléctrico pois o vector de choque encontra-se deslocado anteriormente em relação à maior parte do ventrículo esquerdo (VE). Descreve-se um caso de incapacidade de desfibrilhação pelo CDI resolvido com a implantação de um eléctrodo adicional numa veia tributária do seio coronário.

The obtaining of a compact plant, with less vigor and high productivity, equivalent to a conventional plant, constitutes a strong tendency in the current horticulture, aiming at a raising of the fruit production at the same planted area. One of the techniques that have had success nowadays is the interstem use. This study was developed in a commercial orchard of Randon Agro Silvo Pastoril S.A. (RASIP), located in the Rio Grande do Sul state, Brazil. The purpose of this work was to evaluate the vegetative and productive development of apple trees of 'Imperial Gala' with different lengths of EM-9 interstem. The treatments consisted of five interstem lengths: 10, 15, 20, 25, 30 cm. In the seventh year of implantation the following parameters were evaluated: the height of the plant, the diameter of the 'Imperial Gala' 5 cm above the second graft point, the volume of the tree-head (height, width and length), the number of bud per branch, and the number of fruits per lineal centimeter of branch. Through this study it could be concluded that the greater interstem (30 cm) presented better indices with relation of vigor control. However, the number of fruits per lineal centimeter of branch with the interstem of 10 cm offered only significant superiority, when compared with the interstem of 30 cm. Using interstem technique allows to gather the benefits of the rootstock 'Marubakaido' and to control excessive vigour with the interstem EM-9. Made available in DSpace on 2019-05-15T00:31:01Z (GMT).

To evaluate operated type A aortic dissection by Magnetic Resonance Imaging (MRI), in order to detect long-term complications and identify prognostic indexes of evolution.Prospective study with a three-year period of follow-up. Prognosis evaluation.Outpatient Clinic at Hospital de Santa Maria and Magnetic Resonance Imaging Center at Hospital da Cruz Vermelha.A sample of 37 patients submitted to type A aortic dissection surgery, included sequentially, after exclusion of those with contraindication to MRI.Initial evaluation (clinical and MRI study) at 3 to 4 months and at 1, 2 and 3 years after surgery. The mean follow-up time was 39.3 +/- 2.9 months. We evaluated the following complications over the aorta (aortic graft and five segments of residual aorta) and the aortic valve: aneurysm, pseudoaneurysm, rupture, re-dissection, progressive aortic valve regurgitation, reoperation and death. The prognostic indexes analysed were: presence of residual flap; false lumen patency; presence of re-entry points; false lumen to aorta dimension ratio; initial aortic dimension; increase of aortic dimension.All patients, with the exception of three that died, remained asymptomatic.Aneurysm was detected in 45.9% of patients, located in one or more segments; rupture occurred in three patients, preceded by aneurysm and pseudoaneurysm development; moderate or severe aortic regurgitation was detected in 47.8% of patients. Prognostic indexes: 1. Aneurysm development in each segment yeilded a significant association with: presence of residual flap in the same and other segments; higher initial dimension of the same and other segments, with the exception of the abdominal segment; higher increase in dimension of the same and other segments, with the exception of the abdominal segment; 2. Moderate or severe aortic regurgitation development showed a tendency to association with higher increase in dimension of proximal ascending aorta. 3. No association was found between aneurysm and aortic regurgitation development.Patients operated for type A aortic dissection had a high incidence of late complications which lead to reoperation and in some cases death. The presence of a residual flap, increased aortic dimensions and higher increase rate of aortic dimensions were associated with a complicated evolution. MRI was a very useful technique for long-term monitoring and to identify prognostic indexes of evolution.
