Right ventricular strain as a novel approach to analyze right ventricular performance in patients with heart failure
Speckle tracking echocardiography (STE) has recently applied as imaging technique to accurately evaluate right ventricular (RV) function. STE provides a non-Doppler, angle-independent and objective quantification of RV myocardial deformation. Data regarding feasibility, accuracy and clinical applications of RV strain are rapidly gathering, especially in the setting of heart failure patients. This review describes the fundamental concepts of RV-STE and discusses its emerging clinical applications, focusing on the useful of this technique in the clinical management of patients with advanced heart failure
Determination of Elements in Biological Material by Inductively Coupled Plasma Atomic Emission Spectrometry with Sampling of a Carbonaceous Slurry
Sequential inductively coupled plasma atomic emission spectrometry was used to determine Mg, Ca, K, Na, Fe, Mn, Cu and Zn in five different National Institute of Standards and Technology Standard Reference Materials, by nebulising their carbonaceous slurries obtained by simply warming these matrices with concentrated sulphuric acid using a temperature programme up to 350 °C and gently boiling them for a short period of time. The method has been tested on similar matrices in previous studies, utilising flame atomic absorption spectrometry and electrothermal atomic absorption spectrometry. The results show good precision, expressed as relative standard deviation, s,% (often less than 5%) and accuracy, expressed as relative error, e,% (1-6%). The detection limits for each element are also reported.Sequential inductively coupled plasma atomic emission spectrometry was used to determine Mg, Ca, K, Na, Fe, Mn, Cu and Zn in 5 different National Institute of Standards and Technology Standard Reference Materials (pine needles, dried skim milk, wheat flour, citrus leaves and bovine liver), by nebulizing their carbonaceous slurries obtained by simply warming these matrices with conc. sulphuric acid using a temp. programme up to 350°C and gently boiling them for a short period of time.

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
