The Role of Electroconvulsive Therapy in the Treatment of Severe Bipolar Mixed State
Full text linkElectroconvulsive therapy (ECT) results effective in two-thirds of the patients with severe and drug-resistant mixed states. The episode duration is the main predictor of nonresponse. This practice may increase the risk of mood destabilization and chronic complications and may decrease the chance of recovery in many patients. Compared with the burden of neurologic and metabolic side effects associated with long-term use of complex pharmacologic regimens, ECT should be considered a safe option with a very low incidence of severe adverse events and a long-term nondestabilizing effect
Technical-economic assessment of stone slabs surface finishing using water jet technology
No full textThis paper examines, from an economic standpoint, some of the surface finishing results achieved for stone slabs using high pressure water jets. The results of both the management accounting method and a technical and economic cost analysis method are here applied. The latter method is specifically aimed at verifying and fine-tuning the management analysis model based on the technical coefficient matrix. The second method proposed allows one to examine each
process in detail and easily determine technical–economic models for planning, processing and management. The type of production cost analysis proposed here is original, rigorous and precise. The fact that it captures all the most significant technical aspects of the process and clarifies their economic implications makes it far more preferable to the traditional final accounts analyses. Moreover, this technical and economic cost analysis method allows one to accurately calculate the unit cost of each product
Particulate matter in fly-ash landfills: an abatement technology using anionic flocculant
No full textThis study aims to assess the use of a mix of anionic flocculant and water, in order to reduce the level of fine dust over the ground in a coal fly-ash landfill. So far, the reduction of dust has been achieved by means of water sprays: this method, however, resulted in high costs incurring in the rental of tank trucks; furthermore, the high consumption of water and diffusion of fuel gas both have a major environmental impact. The new method presented below shows how the creation of a thin film over the landfill can limit both wind erosion and dust emission caused by the transit of vehicles during operations. By collecting samplings of dust and laboratory tests, the authors were able to evaluate effectiveness of above mentioned method from a technical, economical and environmental point of view, which has been subsequently resulted in the Company opting for it

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
