Comparison of fibers in geopolymer matrix for structural reinforcement of masonry (FRGP): compatibility, reactivity, durability
No full textGeopolymer matrix bonded fibre nets of UHTSS-steel, carbon, basalt and AR-glass were
prepared on soft mud bricks. Brick reinforcement was measured by three-point flexural tests and fibrematrix-
substrate adhesion by pull-off tests. The durability of the reinforcements was tested by aging and
freeze-thaw cycles. Alkali resistance of fibres was tested in different alkaline solution and comprised
weight loss and tensile strength
Inpatient pulmonary rehabilitation: does it make sense?
Full text linkAmong the nonpharmacological therapies, pulmonary rehabilitation (PR) is particularly appropriate for patients with chronic respiratory impairment who, despite any optimal drug management, are still symptomatic and experience restriction in every day activities. Pulmonary rehabilitation performed in inpatient, outpatient, or home settings demonstrates short- and long-term clinical efficacy. Although disease severity does not inherently dictate candidacy for exercise training, the degree of physiological and functional impairment may influence setting in which the training should occur. Therefore, inpatient rehabilitation is generally best-suited for the most sick and most disabled patients. The overall results from the literature confirm that the inpatient setting for a PR program is a feasible option and does not necessarily result in higher direct costs when balanced against duration and effectiveness in terms of improved outcomes
Basta proprio poco
No full textL'articolo documenta il risultato dell’analisi energetica sviluppata nel’ambito di una Tesi di laurea alla Facoltà di Architettura dell’Università di Bologna- Sede di Cesena- sul progetto di un comune edificio residenziale, seguita dalla simulazione degli incrementi di efficienza energetica ottenibili introducendo alcuni accorgimenti migliorativi, e dal calcolo dei costi corrispondenti.
L'esercizio di simulazione, applicato ad un caso reale, ha dimostrato come il rendimento energetico di un edificio progettato in maniera “tradizionale” possa comunque essere migliorato in maniera sostanziale, senza ricorrere ad alcuna fanta-tecnologia ma anzi solo adottando qualche piccola attenzione ed applicando puntualmente le norme
Mild asthma
No full textNaureckas and Solway (Oct. 25 issue) discuss the treatment of mild intermittent and mild persistent asthma but do not discuss the importance of indoor allergens. Allergens not only are triggers of symptoms, but some are also regarded as causal factors in the development of the disease. Because they continuously induce allergic inflammation of the airways, allergens may be more important as a cumulative cause of bronchial hyperreactivity than as triggers of acute attacks. Furthermore, longitudinal studies have shown an accelerated decline in the forced expiratory volume in one second in older adults who are exposed to certain allergens. In other diseases that are caused by exposure to foreign substances, such as hypersensitivity pneumonitis, avoidance of exposure to relevant antigens is the first line of treatment. In asthma, environmental control measures to reduce exposure to indoor allergens should be considered a primary antiinflammatory treatment. Such measures should help to prevent the development of chronic airflow limitation and, therefore, reduce the need for further pharmacologic treatment
Chronic obstructive pulmonary disease: definition and classification of severity
Full text linkChronic obstructive pulmonary disease is characterized by airflow limitation that is not fully reversible and is usually both progressive and associated with an abnormal inflammatory response of the lungs to noxious particles or gases, particularly tobacco smoke. Diagnosis of chronic obstructive pulmonary disease is primarily based on a reduction of forced expiratory volume in one second/forced vital capacity ratio < 70% post-bronchodilators. The characteristic symptoms of chronic obstructive pulmonary disease are cough, sputum, and dyspnea upon exertion. Based on airflow limitation as measured by spirometry, chronic obstructive pulmonary disease can be classified as mild, moderate, severe and very severe. Chronic obstructive pulmonary disease can coexist with asthma, although the inflammation characteristic of chronic obstructive pulmonary disease is distinct from that of asthma

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
