Did Your Mother Go To Bimbo School?: Naming Schools, Power, and Politics in Canada’s Prairie West
Authors: Lehr John C. , McGregor Brian
Published: December 2015

Naming converts space to place. Place names are often the manifestation of military and political power. The victors write history and embed their culture and power in the landscape by naming and renaming places. In Canada’s Prairie West, after 1870, Aboriginal place names were submerged beneath a tide of British imperial nomenclature bestowed by major corporations. Agricultural immigrants from Europe found it difficult to mark their presence in the landscape by naming settlements, but school names were generally assigned locally. By naming schools, otherwise powerless groups from Eastern Europe marked their presence in the rural landscape. Naming or renaming them reflected the strength of community power, the community’s weltanschaaung , and fluctuations in the influence of the Anglophone elite. L’acte de nommer convertit l’espace en un lieu. Le nom des lieux (toponyme) sont souvent la manifestation du pouvoir politique et militaire. Les vainqueurs écrivent l’histoire et intègrent leur culture et pouvoir dans le paysage en nommant et en renommant des lieux. Après 1870, dans la région des Prairies de l’Ouest du Canada, les toponymes autochtones ont été submergés sous une marée de nomenclature impériale Britannique conférée par les grandes entreprises commerciales. Les immigrants agricoles en provenance d’Europe ont trouvé difficile de marquer leur présence dans le paysage en nommant des villages. Toutefois, cela n’était pas le cas pour le nom des écoles qui était généralement attribué localement. L’acte de nommer leurs écoles a permis à des groupes d’Europe de l’Est de marquer leur présence dans le paysage rural. Ainsi, nommer ou renommer les écoles reflète le pouvoir de la communauté, l’weltanschauung de la communauté, et les fluctuations de l’influence de l’élite anglophone.
Socialization to Student Affairs: Early Career Experiences Associated With Professional Identity Development
Authors: Hirschy Amy S. , Wilson Maureen E. , Liddell Debora L. , Boyle Kathleen M. , Pasquesi Kira
Published: December 2015

In this study, the authors propose and test a model of professional identity development among early career student affairs professionals. Using survey data from 173 new professionals (0–5 years of experience), factor analysis revealed 3 dimensions of professional identity: commitment, values congruence, and intellectual investment. Multivariate analyses found significant associations of age, master’s program characteristics, and influential people and experiences (e.g., interactions with professional colleagues and associations) with the dimensions of professional identity. Findings indicated key socialization experiences during and after graduate school were associated with the development of professional identity. The authors conclude with recommendations for practice and research.
The Quotation Collectors: A Conspectus of Readers for the Oxford English Dictionary
Authors: Gilliver Peter
Published: December 2015

Throughout the history of the Oxford English Dictionary its compilers have invited contributions from the public. Anyone, throughout the English-speaking world, could help by reading, and sending in quotations from, texts. This article draws on published and archival sources to describe the work of a selection of the several thousand individuals who have contributed to the OED in this way during the century and a half of the project’s existence, presenting some biographical details about them and also examining the ways in which the content of the Dictionary can be seen to reflect their individual contributions; these case studies can be used as a lens through which to view the changing nature of the Dictionary and its methodology over time.
Hollywood Is a Verb: Los Angeles Tackles the Oxford English Dictionary
Authors: Rickman Rebecca
Published: December 2015

In March 2016 the Library Foundation of Los Angeles and the Los Angeles Public Library will produce a series of events called “Hollywood Is a Verb: Los Angeles Tackles the Oxford English Dictionary .” Comprising approximately seventy programs, the project will be mounted at the Los Angeles Central Library and in branch libraries and other cultural venues across the city. In looking at the OED through a California lens, the programs will highlight enrichment of the English language through the incorporation of words from other languages and cultures, and it will emphasize the contribution of readers from around the globe in creating and developing the dictionary itself.
Corpus Linguistics in Trademark Cases
Authors: Kilgarriff Adam
Published: December 2015

Dictionaries and corpora may both be used as evidence to help decide legal cases. In certain trademark disputes—and in this paper—the central issue is whether a disputed term exhibits the linguistic behavior characteristic of a name (identifying the source or producer of a product or service) or the linguistic behavior characteristic of an ordinary common noun. Corpora are particularly useful in resolving such trademark disputes, but using corpora for this purpose requires attention to several important considerations, both linguistic and non-linguistic. This paper explores several of those linguistic considerations and discusses several legal cases involving well-known terms.
Barthes and the Voice: The Acousmatic and Beyond
Authors: ffrench Patrick
Published: December 2015

Barthes’s attention to the voice features a concern with singularity; the voice is subject to an absolutely singular and amorous evaluation. Comparison with the notion of the acousmatic , a term introduced by Pierre Schaeffer to move towards a formal attention to the sonic object alone, can shed light on Barthes’s account of the voice. However, through a reading of the celebrated episode of the grandmother’s telephone call in Proust’s Recherche and its place in Barthes’s writing, I argue that for Barthes the voice bears a more radical acousmatisation since it is located beyond the phenomenal field and exists insofar as it has already disappeared.
Otamanshchyna ?: The Self-Formation of Ukrainian and Russian Warlords at the Beginning of the Twentieth and Twenty-First Centuries
Authors: Gilley Christopher
Published: December 2015

SUMMARY: The article reviews some of the empirical and terminological problems associated with examining the autonomous military formations active in the current war in Ukraine. The article suggests that an understanding of a historical example of such independent bands – otamanshchyna during the Russian Civil War, 1917–1922 – might offer a means of studying the current participants in the war in the Donbas. This approach shows how military men actively engage in the construction of identities to make sense of their activity. It also reveals that the current commanders have often drawn on a set of invented traditions similar to their Civil War counterparts – above all related to the early modern Cossacks. Статья посвящена обсуждению некоторых сюжетов и терминологических проблем, связанных с феноменом независимых вооруженных формирований в современной российско-украинской войне. Для лучшего понимания того, что движет участниками войны на Донбассе, автор предлагает обратиться к историческому прецеденту подобных самостоятельных банд – “отаманщине” периода гражданской войны 1917−1922 гг. Этот подход позволяет увидеть, как взявшие в руки оружие люди начинают конструировать собственную идентичность, пытаясь разобраться в смысле своих поступков. Статья также показывает, что современные полевые командиры часто опираются на “изобретенные традиции”, подобно своим предшественникам времен гражданской войны – прежде всего, выбирая себе в пример историческое казачество раннего Нового времени.
The Lived Exemplarity of HeLa: A Matter of Lifedeath

A Very Proud Nation: Nationalism in American Foreign Policy
Authors: Brice Benjamin
Published: December 2015

Contrary to popularly espoused views in media and policy circles, the underpinnings of US foreign policy find basis not only in the country’s liberal value system, but also in a deeply-held and largely unique concept of nationalism. In fact, moral ideals are often a purported justification for US foreign policy. Another important driver is the country’s national pride. Consideration of US foreign policy—particularly since the Cold War—makes clear that US nationalism has had a prominent role in nation’s policymaking. This article discusses US nationalism, as well as three obstacles that make it difficult to detect the notable influence America’s national pride has on the country’s foreign policy.
“Nkrumah Lives Forevermore”: Independence, Symbolic Nationalism, and Nation-Building in Ghana
Authors: Linzy Benjamin
Published: December 2015

After more than a century of British colonial rule, how does a newly formed nation-state forge a cohesive national identity out of a society whose population identifies with one out of a multitude of ethnic tribal traditions? In Building the Ghanaian Nation-State: Kwame Nkrumah’s Symbolic Nationalism , historian Harcourt Fuller analyzes how independent Ghana’s first political leader dealt with this imperative question. In particular, this review focuses on President Kwame Nkrumah’s use of visual symbols as mechanisms for augmenting his authority and strengthening the Ghanaian state.

Authors: Čejka Tomáš , Kroftová Klára , Šmidtová Markéta , Zigler Radek
Published: December 2015

The major requirements for present day cultural heritage conservation include the minimization of interventions in historic structures, non-invasiveness and, last but not least, reversibility of rehabilitation and strengthening interventions. Due to these requirements, composites based on high-strength fibres and epoxy resin are increasingly applied during the rehabilitation, renovation and strengthening of building structures. The article points out potential applications of these materials in the renovation, rehabilitation and strengthening of half-timbered constructions.
FIRST STEPS IN URBAN PLANNING OF BULGARIAN CITIES WITH PARTICIPATION OF CZECH ARCHITECTS AND ENGINEERS AT THE TURN OF 19TH AND 20TH CENTURIES
Authors: Brankov Nikolay
Published: December 2015

This article focuses on beginnings of the urban planning and first organized planning activities of Bulgarian cities at the turn of 19th and 20th centuries when many Czech engineers and architects participated in significantly. A common feature of all Bulgarian cities was irregular structure and build-up area. The main task of the Czech engineers was to cope with this situation and to design modern cities. In general, the original structure did not make planning easy and unambiguous. Planning of the cities destroyed in the Russian-Turkish war in 1877-78 was easier. A possibility to apply a new city structure freely existed in Stara Zagora and partially in Nova Zagora. A usual principle was straightening of the streets where the engineers used original street network and the new modern streets were built according to it, e.g. the centre of Kystendil and the old part of Nova Zagora. These principles were used also in some central parts of Sofia and Plovdiv. The city of Sofia itself is a distinctive example. Although the original structure was preserved during the war and in the first steps the principle of straightening of the streets in the centre was applied, the other parts of Sofia were designed with a new structure and the old city disappeared. Plovdiv is in contrary to Sofia and its original structure was preserved as an old city and the new one was joined to it in neighbourhoods.
INFLUENCE OF CYCLIC LOADING ON THE DEFLECTION DEVELOPMENT OF CONCRETE SPECIMENS
Authors: Foglar Marek , Göringer Jakub
Published: December 2015

Durability of the structures is one of the most discussed issues of last decades. It is one of the most easily measured properties for analysis during the structural lifetime. Concrete deflections increase over time due to rheological effects (creep and shrinkage) in addition cyclic creep can be observed on the cyclically loaded structures. The deflection increase due to the cyclic creep is not properly quantified. The fatigue damage function presented in this paper provides an analytical solution for the deflection development due to cyclic loading. The evaluation of the deflection is based on the reduction of the initial modulus of elasticity.Main principles of the function are discussed and compared with the standardized approaches for the fatigue assessment. Experimental verification of the fatigue damage function was carried out on reinforced concrete specimens and on prestressed concrete slab. To improve the standardized approaches, the real stress distribution was considered with the use of newly-developed method of partial integration over the height of the specimen compressive zone.The deflection increase due to cyclic loading was measured regularly with inductive displacement transducer. Comparison of the measured values and the values calculated using the presented function shows good agreement. The fatigue damage function can be used easily in “in-hand” calculations, or can be inserted into FEM-based software and used in practical applications for assessing the increase in the deformations of concrete structural elements caused by cyclic loading.

Authors: Tominaga Kazunari , Fujikawa Yoshiko , Tanaka Fumio , Tanigawa Tetsuya , Watanabe Toshio , Fujiwara Yasuhiro , Arakawa Tetsuo
Published: December 2015

Functional dyspepsia (FD) and irritable bowel syndrome (IBS) are functional diseases without identified organic cause and intruduced as part of the Rome III criteria published in 2006. Because of non‐organic diseases, pharmacological treatment (not invasive surgical treatment) is the preferred therapy for such diseases. Meanwhile, evidence‐based clinical practice guidelines for FD and IBS have been published in Japan. However, no definite therapeutic strategy for FD and IBS has yet been established. To understand more appropriate treatments according to the respective pathophysiology, this review introduces the several pharmacological treatments including current standards and proposes future promising therapies based on these guidelines. First, this review covered clinical evidence for standard and recommended drugs such as acid suppressants, prokinetics, probiotics, and bulking polymers for the management of FD and IBS. Next, this review progressed to propose future promising treatments for their managements. A comprehensive understanding of relevant therapeutic regimens and pharmacological treatment using drug candidates including future promising drugs is required for the optimal and more effective treatment of FD and IBS.
Genetics of Asthma
Authors: Hizawa Nobuyuki
Published: December 2015

Asthma runs strongly in families and has a heritability rate of up to 60%. Genetic studies offer a structured means for understanding the causes of asthma and for identifying targets of treatment for the syndrome. As with studies of other common complex diseases, genetic studies of asthma have led to considerable advances in the understanding of this disease. Genome‐wide association studies have greatly advanced the identification of the most important genes predisposing individuals to airway diseases. Several genes act in pathways that communicate the presence of epithelial damage to the adaptive immune system ; identification of these genes has provided a new focus for the development of effective therapies. Genetic findings have also led to a reassessment of the primacy of atopy in asthma and eczema (atopic dermatitis) ; these findings indicate that atopy is secondary to epithelial damage or other events in both diseases. Despite these advances, only a small component of the overall genetic contribution to asthma has been identified. This missing heritability may be due to multiple genes of small effects (polygenes), rare highly penetrant mutations, or epigenetic modifications of gene function. Further work is necessary to understand the biological consequences of the known susceptibility variants ; the most immediate challenge in this field is the systematic analysis of the precise functions of these genes in the pathogenesis of asthma. Detailed functional dissection of the roles of these genes in asthma will point the way to new therapies for the disease.
Geographic Maldistribution of Physicians in Japan : Increasing the Number of Generalists is One Solution
Authors: Matsumoto Masatoshi , Takeuchi Keisuke , Yokobayashi Kenichi , Tazuma Susumu
Published: December 2015

Despite massive intervention from Japan's national and local governments, the skewed distribution of physicians remains a serious social problem. This review paper summarizes past literature and proposes a future strategy to deal with this sophisticated issue based on scientific evidence. There are several ways to achieve a more balanced distribution, the most feasible of which is to increase the number of generalists. This increase might be imminent with the establishment of a formal board certification for general practitioners (sougou‐shinryou‐i) and raising the number of rural subquota (chiikiwaku) entrants to medical school. All the stakeholders should co‐operate to take advantage of this great opportunity to increase the number of generalist physicians and solve Japan's distribution problem.

Published: December 2015

Acute aortic dissection (AAD) is a fatal disease and delay in diagnosis results in deteriorated prognosis. A 55‐year‐old man presented to our hospital with aphasia because of a suspected stroke. Although the lack of pain made diagnosis difficult, we diagnosed Stanford type A AD as the underlying cause of his stroke. Two possible explanations were considered for the lack of pain. First, although the stroke was caused by AD, the stroke itself prevented the patient from feeling the pain. Second, the aphasia prevented him from complaining about the pain. Therefore, we believe that physicians require a high clinical index of suspicion for AD considering the possibility of painless AD or miscommunication secondary to aphasia.

Published: December 2015

The purpose of this study is to determine which and how often conflict management strategies are used in case of any conflict situations by school principals attending primary schools. This study aims to identify to what extent the school administrators use the strategies of integration, reconciliation, compromise, domination and avoidance when handling conflicts and whether there are differences based on factors including teacher’s gender, marital status, or whether they assume a role in management, or the rank of their position, their age, educational level and seniority. 300 teachers attending primary and middle schools in Kağıthane, Istanbul were administered the “Conflict Management Styles Survey” as part of the research which was conducted using the descriptive survey model.  The results of the study showed that the school principles use the integration strategy the most; there is no significant difference in the opinions of teachers based on factors such as gender, marital status, management experience, or educational status; there is a significant difference in the feedback on integration and reconciliation strategies based on the factor of rank of position held; and there is a significant difference in the feedback from teachers about integration, avoidance and reconciliation strategies both based on the factor of age and factor of seniority.

The pituitary TGFβ1 system as a novel target for the treatment of resistant prolactinomas
Authors: Recouvreux M Victoria , Camilletti M Andrea , Rifkin Daniel B , Díaz-Torga Graciela
Published: December 2015

Prolactinomas are the most frequently observed pituitary adenomas and most of them respond well to conventional treatment with dopamine agonists (DAs). However, a subset of prolactinomas fails to respond to such therapies and is considered as DA-resistant prolactinomas (DARPs). New therapeutic approaches are necessary for these tumors. Transforming growth factor β1 (TGFβ1) is a known inhibitor of lactotroph cell proliferation and prolactin secretion, and it partly mediates dopamine inhibitory action. TGFβ1 is secreted to the extracellular matrix as an inactive latent complex, and its bioavailability is tightly regulated by different components of the TGFβ1 system including latent binding proteins, local activators (thrombospondin-1, matrix metalloproteases, integrins, among others), and TGFβ receptors. Pituitary TGFβ1 activity and the expression of different components of the TGFβ1 system are regulated by dopamine and estradiol. Prolactinomas (animal models and humans) present reduced TGFβ1 activity as well as reduced expression of several components of the TGFβ1 system. Therefore, restoration of TGFβ1 inhibitory activity represents a novel therapeutic approach to bypass dopamine action in DARPs. The aim of this review is to summarize the large literature supporting TGFβ1 important role as a local modulator of pituitary lactotroph function and to provide recent evidence of the restoration of TGFβ1 activity as an effective treatment in experimental prolactinomas.
Value Orientation as Structural Component of Personality in Mountain Regions
Authors: Lemko Galina
Published: December 2015

This paper, presented at the Conference Plenary, is devoted to the problem of formationof values and value orientations of a personality in mountain regions. The author asserts that valueorientation in mountain regions is a complex formation, which includes different levels and formsof interaction of public and individual personality. The article also regards and analyzes thehierarchy of values. It is mentioned that the personality value orientations in mountain regionsdon’t only determine the motivation of individual behavior but also forms his world outlook. Thespecial attention is also devoted to the pseudo-values. The author points out that they do notcontribute to human self-realization. The article also analyzes the reasons of forming of the valueorientation in mountain regions and gives the classification of people in accordance with thecommitment to certain values. The author touches the problem of cultural values of modern youth,the influence of electronic mass media and comes to the conclusion that classical culture begins tolose value and attractiveness. In conclusion the author says that the valued orientations inmountain regions occupy the central place in the psychical adjusting of man’s behavior. That iswhy considerable attention is spared to the study of valued-semantic sphere of personality on themodern stage of development of pedagogical science.

Published: December 2015

CONTEXT:

Kangaroo mother care (KMC) is an intervention aimed at improving outcomes among preterm and low birth weight newborns.

OBJECTIVE:

Conduct a systematic review and meta-analysis estimating the association between KMC and neonatal outcomes.

DATA SOURCES:

PubMed, Embase, Web of Science, Scopus, African Index Medicus (AIM), Latin American and Caribbean Health Sciences Information System (LILACS), Index Medicus for the Eastern Mediterranean Region (IMEMR), Index Medicus for the South-East Asian Region (IMSEAR), and Western Pacific Region Index Medicus (WPRIM).

STUDY SELECTION:

We included randomized trials and observational studies through April 2014 examining the relationship between KMC and neonatal outcomes among infants of any birth weight or gestational age. Studies with <10 participants, lack of a comparison group without KMC, and those not reporting a quantitative association were excluded.

DATA EXTRACTION:

Two reviewers extracted data on study design, risk of bias, KMC intervention, neonatal outcomes, relative risk (RR) or mean difference measures.

RESULTS:

1035 studies were screened; 124 met inclusion criteria. Among LBW newborns, KMC compared to conventional care was associated with 36% lower mortality(RR 0.64; 95% [CI] 0.46, 0.89). KMC decreased risk of neonatal sepsis (RR 0.53, 95% CI 0.34, 0.83), hypothermia (RR 0.22; 95% CI 0.12, 0.41), hypoglycemia (RR 0.12; 95% CI 0.05, 0.32), and hospital readmission (RR 0.42; 95% CI 0.23, 0.76) and increased exclusive breastfeeding (RR 1.50; 95% CI 1.26, 1.78). Newborns receiving KMC had lower mean respiratory rate and pain measures, and higher oxygen saturation, temperature, and head circumference growth.

LIMITATIONS:

Lack of data on KMC limited the ability to assess dose-response.

CONCLUSIONS:

Interventions to scale up KMC implementation are warranted.
Immigrant Families, Children With Special Health Care Needs, and the Medical Home
Authors: Kan Kristin , Choi Hwajung , Davis Matthew
Published: December 2015

OBJECTIVE:

Immigrant children in the United States historically experience lower-quality health care. Such disparities areconcerning for immigrant children with special health care needs (CSHCNs). Our study assesses the medical home presence for CSHCN by immigrant family type and evaluates which medical home components are associated with disparities.

METHODS:

We used the 2011 National Survey of Children’s Health, comparing the prevalence and odds of a parent-reported medical home and 5 specific medical home components by immigrant family types using bivariate and multivariate logistic regression.

RESULTS:

Foreign-born CSHCNs were less likely than CSHCNs with US-born parents to have a medical home (adjusted odds ratio = 0.40, 95% confidence interval 0.19–0.85). The adjusted prevalence of having a medical home was 28% among foreign-born CSHCNs (P < .05) and 37% among CSHCNs with a foreign-born parent (P < .001), compared with 49% among CSHCNs with US-born parents. Foreign-born children without special needs also had a lower odds of a medical home, compared with children with US-born parents (adjusted odds ratio = 0.62, 0.46–0.83). The medical home component most frequently absent for immigrant children without special needs and CSHCNs with a foreign-born parent was family-centered care. In contrast, foreign-born CSHCNs most often lacked care coordination (adjusted prevalence = 37% versus 56% for CSHCNs with US-born parents; P < .05).

CONCLUSIONS:

Disparities in medical home presence for CSHCNs appear to be exacerbated by immigrant family type. Efforts focused on improving family-centered care and care coordination may provide the greatest benefit for immigrant CSHCNs.
Takotsubo Cardiomyopathy

Takotsubo cardiomyopathy (TTC) is an acute, stress-induced cardiomyopathy with an increased prevalence in post-menopausal women. The syndrome is most frequently precipitated by an acute emotional or physical stressor and mimics acute myocardial infarction with symptoms, electrocardiogram (ECG) changes and cardiac troponin elevation that are indistinguishable from those caused by plaque rupture or coronary thrombosis. Diagnosis of TTC is made when coronary angiography reveals no obstructive coronary artery disease and the left ventricle demonstrates apical ballooning and basal hypercontractility. Other ventricular patterns have also been described. An abnormal myocardial response to the catecholamine surge from an emotional or a physical stressor is implicated in the pathophysiology, but the reasons for the high prevalence of TTC presentations in post-menopausal women are unknown. Several mechanisms including multi-vessel coronary vasospasm, endothelial and coronary microvascular dysfunction and direct catecholamine toxicity have been proposed. No specific guidelines for treatment of TTC have been established, but treatment is based on the American Heart Association/ American College of Cardiology guidelines for acute coronary syndrome/acute myocardial infarction and heart failure guidelines. In this review article, we discuss the characteristic clinical presentation of TTC and the commonly proposed mechanisms.

Hypertrophic cardiomyopathy (HCM) is a hereditary primary myocardial disease that is most commonly due to mutations within genes encoding sarcomeric contractile proteins and is characterised by left ventricular hypertrophy in the absence of a cardiac or systemic cause. Although the overall prognosis is relatively good with an annual mortality rate <1 %, the propensity to potentially fatal ventricular arrhythmias is the most feared complication. The identification of patients at risk of arrhythmogenic sudden cardiac death (SCD) is an essential component in disease management. Aborted SCD and malignant ventricular arrhythmias are the most powerful risk factors for SCD and ICD implantation is recommended in such circumstances. The selection of patients who may benefit from ICD therapy for primary prevention purposes is more challenging. The heterogeneous nature of the disease and the variation in trigger factors provides an adequate explanation for the low predictive accuracy of most conventional risk factors in isolation. A new risk model for risk stratification proposed by the European Society of Cardiology HCM outcome group shows promise but requires validation in different cohorts. The ICD is the only effective therapy in preventing SCD for the disease with a relatively low adverse event rate, but most deaths occur in relatively young patients. However, it is also difficult to ignore the complications with the ICD, therefore, the strive to perfect risk stratification in HCM should continue to ensure that only the most high-risk patients receive an ICD.

Impaired interatrial conduction or interatrial block is now well-documented but is not described as an individual electrocardiographic (ECG) pattern in the majority of ECG literature. In fact the term atrial abnormality has been adopted to encompass both left atrial enlargement (LAE) and interatrial block. In this paper, we maintain that interatrial blocks and atrial enlargement are separate entities, and that interatrial blocks, similar to other types of blocks at sinoatrial, AV junctional, and ventricular level, exhibit a specific ECG pattern that may present first, second, and third degree types of conduction block. The third degree or advanced interatrial block (A-IAB) is frequently associated with atrial fibrillation/atrial flutter (AF/AFl), and constitutes a true newly-described syndrome.
Twelve Months Dual Antiplatelet Therapy after Drug-eluting Stents – Too Long, too Short or Just Right?

Published: December 2015

Dual Antiplatelet Therapy (DAPT) remains a cornerstone in the secondary prevention of coronary artery disease. Further, in contemporary practice, a period of DAPT is considered a mandatory requirement after intracoronary stents to prevent stent thrombosis (ST), a complication associated with heart attack and a mortality rate of up to 40 %. In current clinical practice, the default strategy in most centres is 12 months’ DAPT followed by aspirin alone for life. However, the optimal duration of DAPT, particularly given the rapid iterative turnover of drug-eluting stents (DES) is the subject of discrepant evidence and clinical uncertainty. In particular, the 12-month regimen is based upon relatively weak evidence. A series of fairly small randomised trials, not powered to look specifically at ST as an endpoint, have recently indicated that there is no apparent disadvantage to shorter versus longer duration DAPT (including several trials of >12 months versus 12 months) when looking at various composite clinical endpoints. By contrast, the 9,961 patient DAPT trial, published in theNew England Journal of Medicineat the end of 2014, demonstrated clinical outcome benefit, including a significantly lower rate of ST as a predefined primary endpoint, in DES patients randomised to 30 months’ DAPT compared to stopping at 12 months. Here, the authors to assess the data, including the most recent meta-analyses, in an attempt to answer the question: DAPT after DES...12 months, longer or shorter?

Published: December 2015

Transcatheter aortic valve implantation (TAVI) has reached relative maturity for the treatment of severe, symptomatic aortic stenosis (AS). TAVI for patients with smaller anatomy is a challenging procedure due to specific anatomical difficulty and complications including annulus rupture and vascular complications. Prevention of these complications, and the introduction of a newer-generation and lowerprofile TAVI system, will encourage the prevalence of TAVI for patients with smaller anatomy.

Lateritic material lies over nearly 75% of the Brazilian surface area; but not more than 30% of this material is exploited. The expressive volume of clay minerals associated to the ores is the main reason of this low figure, especially because clay minerals are very complex, most of the time, impossible to concentrate. Under this circumstance, a proper mineral identification and the knowledge of the clay mineral structure are essential for the best mineral processing route choice.This study describes an optimized methodology to characterize a Cu-lateritic ore, mainly composed of Cu-bearing clay minerals. Cations saturations and particle sizes separation, combined with X-ray diffraction, mid infrared spectroscopy and scanning electron microscopy allow concluding that this Cu-lateritic ore is mainly composed of smectites, micas and kaolinite; furthermore, the copper is especially associated to mica and secondarily to smectite.

A usina do Sossego foi a primeira operação da Vale S.A. a operar com um moinho semi-autógeno (SAG) para o processamento de minério sulfetado de cobre e ouro. A usina está localizada no sudeste do estado do Pará. O circuito de cominuição foi projetado para processar 41.000 toneladas por dia de run of mine, sendo o circuito composto por um britador primário, um moinho semi-autógeno de 11,6 m de diâmetro que opera em circuito fechado com britadores cônicos, seguido de dois moinhos de bolas de 6,7 m de diâmetro. O projeto do circuito se baseou em dados de extensa campanha piloto, assim como em simulações baseadas nos resultados de ensaios de caracterização em amostras de furos de sonda. Após o comissionamento do circuito, observou-se que algumas variáveis estavam contribuindo para vazões horárias abaixo das esperadas. Uma série de otimizações e adequações foram realizadas ao longo dos 10 anos de operação do moinho semi-autógeno, incluindo mudança na área aberta, tamanho e disposição das aberturas das grelhas, perfil dos revestimentos e mudanças no plano de fogo da mina. Este trabalho descreve os principais aspectos do projeto do circuito, assim como as otimizações realizadas ao longo dos primeiros anos de operação.

O tipo de aerador (sparger), assim como a dosagem de espumante, possuem um papel fundamental no controle do tamanho de bolha em colunas de flotação, com influências na cinética de flotação e no desempenho metalúrgico (recuperação e teor). Este trabalho apresenta estudos de avaliação online da distribuição de tamanho de bolhas geradas por um sparger tipo tubo poroso e um micro-venturi acoplados em uma coluna de flotação minipiloto automatizada. Os efeitos da dosagem de espumante DF250 (éter metílico de polipropilenoglicol) e da vazão de ar no tamanho de bolha e no holdup foram avaliados. O diâmetro médio de bolha foi fortemente influenciado pela dosagem de espumante para ambos os spargers; entretanto o micro-venturi foi mais eficiente do que o tubo poroso, por dispersar o ar mais finamente e com menores dosagens de espumante. Os menores diâmetros médios obtidos, de acordo com as condições experimentais aplicadas, foram de 1,25 mm (154,8 mg/L de DF250) para o tubo poroso e 0,45 mm (44,2 mg/L de DF250) para o micro-venturi.

O parâmetro mais amplamente utilizado no dimensionamento de moinhos é o WI de Bond. Contudo, dependendo das características físicas do minério nem sempre é possível determina-lo de forma adequada. Alguns minérios, ao serem preparados para o teste padrão de Bond, geram uma quantidade excessiva de finos, obtendo um valor de F80 muito pequeno. Este fato trará uma distorção para os valores encontrados de work index e resultará em uma situação não prevista pela norma para determinação do BWI. Este artigo discute o efeito do escalpe no valor encontrado para o work index e apresenta considerações sobre algumas situações não preditas pela  norma

Os minérios atualmente lavrados têm apresentado teores cada vez menores, impactando no aumento da produção de rejeitos e necessitando de técnicas para viabilizar sua disposição a seco. Entre essas técnicas, espessamento e processos de agregação de partículas, como a floculação, são utilizados para a produção de líquidos clarificados e de pastas minerais. Devido à menor quantidade de água, as pastas apresentam inúmeras vantagens ambientais e tecnológicas, sendo  necessário considerar previamente suas propriedades reológicas, entre elas a altura de abatimento. O presente estudo objetivou caracterizar as pastas minerais obtidas a partir do espessamento de lamas, quanto ao seu abatimento, e selecionar a dosagem de floculante que apresente as melhores respostas de sedimentação e clarificação dos líquidos sobrenadantes. Os resultados foram obtidos através de ensaios de sedimentação descontínua em proveta, com floculante catiônico e aniônico, apresentando como única variável operacional a dosagem de floculante. Os líquidos clarificados obtidos em cada ensaio tiveram sua turbidez determinada por turbidímetro digital. No que se refere aos parâmetros reológicos, testes slump foram utilizados para determinação da consistência das pastas minerais, em ampla faixa de concentração de sólidos. Resultados mostraram que o floculante catiônico apresentou melhor resposta de sedimentação e clarificação de sobrenadante, cuja velocidade de sedimentação e turbidez foram, respectivamente, 2,40cm/s e 9,4NTU. Para pastas com mais de 80% de sólidos, não foi observado abatimento significativo, próximo a 0,3cm, ao passo que, para polpas diluídas, as mesmas se espalhavam totalmente pela superfície.

A magnetita (Fe3O4) é um óxido magnético de ferro natural formado por íons Fe+2 e Fe+3. É o mais comum mineral fortemente magnético, estando presente em pequenas quantidades em quase todas as rochas e também nos meteoritos. A nanotecnologia está largamente presente em todo nosso dia a dia. É possível encontrar diferentes aplicações nas mais diversas áreas da indústria: Eletroeletrônicos, metalurgia, cerâmicos, tintas, tecidos, indústria de polímeros, medicina entre outras. Atualmente a Anglo American Fosfatos do Brasil não produz magnetita, mas possui uma produção de rejeito de 2 Mt (milhões toneladas) com teores de magnetita por volta de 40%, na granulometria de 2 mm, sendo esse material enviado integralmente para a barragem de rejeito. O aproveitamento desse material, dada uma recuperação de 60%, traria um crescimento de 78,5 milhões de dólares no PIB do estado. A maior parte da produção de ferro do Brasil é feita por flotação, sendo que tal tipo de produção prejudica a utilização da magnetita, especificamente, para a produção de ferrofluidos nanomagnéticos, devido a enorme quantidade de produtos químicos, principalmente surfactantes, envolvidos na etapa de flotação. Contudo o objetivo desse trabalho é obter um concentrado de magnetita proveniente do rejeito da produção de rocha fosfática por jigagem, para que a mesma possa ser usada na produção de ferrofluidos. Os resultados da utilização do jigue como separador dos minerais são satisfatórios na produção de magnetita para ferrofluidos como coproduto da produção de concentrado de rocha fosfática.

En Chile la minería se desarrolla principalmente en  la concentración de cobre, molibdeno, oro y plata, mediante el proceso de flotación. Este genera grandes tonelajes de relaves que contienen diversas minerales, principalmente pirita. Dado que estos minerales se depositan en los tranques, estos pueden generar aguas ácidas; se propone como alternativa la desulfuración de los súlfuros por flotación. En una primera parte se estudió la flotabilidad de la pirita en un tubo Hallimond, utilizando como colector AP 404. Luego se realizaron pruebas de flotación a nivel de laboratorio en celda Denver D-12, utilizando pulpa de relave fresco de la etapa rougher de un circuito de flotación de cobre,  determinando el pH óptimo y dosificación de colector y espumantes. Pruebas de cinética de flotación permitieron determinar el tiempo óptimo de flotación tanto para la etapa rougher como  para la etapa scavenger. Se concluye que la flotación de los relaves sea una técnicamente factible su desulfuración,  obteniendo relaves que contienen  0,08% de pirita.

Neste trabalho é apresentado uma metodologia de caracterização tecnológica de minério aurífero contendo material carbonoso, por meio de separações minerais, seguido de amalgamação e cianetação dos produtos obtidos, e emprego de sistema de análise de imagens (MLA, Mineral Liberation Analyser - FEI) para análise quantitativa das associações do ouro de forma a fornecer subsídio para delimitação de alternativas de processo para pesquisas subsequentes objetivando a mitigação das perdas de ouro. A análise granulométrica mostrou distribuição preferencial do ouro em frações acima de 0,074 mm e o estudo mineralógico identificou associação mineralógica do ouro predominantemente com sulfetos (64%). A recuperação do ouro foi de 83,9%, e a da parcela não recuperada, 62,6% está nas frações finas (-0,037 mm) forte indicador de perda do ouro adsorvido no material carbonoso.
