Application of sugarcane bagasse ash in the production of low cost soil-cement brick

Amaral, Mateus C.,Holanda, Jose N.F. Techno-Press 2017 Advances in environmental research Vol.6 No.4

This work investigated the use of sugarcane bagasse ash (SCBA) generated by an energy cogeneration process in sugarcane mill as an alternative raw material in soil-cement brick. The SCBA obtained from a sugarcane mill located in southeastern Brazil was characterized with respect to its chemical composition, organic matter content, X-ray diffraction, plasticity, and pozzolonic activity. Soil-cement bricks were prepared by pressing and curing. Later, they were tested to determine technical properties (e.g., volumetric shrinkage, apparent density, water absorption, and compressive strength), present crystalline phases, and microstructural evolution. It was found that the SCBA contains appreciable amounts of silica ($SiO_2$) and organic matter. The results showed that the SCBA could be used in soil-cement bricks, in the range up to 30 wt.%, as a partial replacement for Portland cement. These results suggest that the SCBA could be valorized for manufacturing low-cost soil-cement bricks.

Objective: The objective of this study was to evaluate the prevalence and incidence of accidents with biological material, the level of knowledge, and compliance to standard precautions (SPs) among dentists, physicians, nurses, and dental and medical students. Methods: A closed cohort study with a prospective and retrospective component was conducted between August 2014 and September 2015. The participants were contacted in two moments during the follow-up period, during which a structured questionnaire divided into six sections was used; the interviews were conducted during the follow-up period (Month 6) and at the end of the observation period (Month 12). Results: The global prevalence of accidents in the previous 12 months was 10.2%, with a difference between professionals and students (13.0% vs. 5.1%, respectively; p < 0.003). The incidence rate was 6.49 per 100 person/year, with difference between the groups (6.09 per 100 person/year in professionals and 7.26 per 100 person/year in students), type of specialization (hazard ratio, 3.27), and hours worked per week (hazard ratio, 2.27). The mean of compliance to SP was 31.99 (3.85) points, with a median of 33 (30, 35) points against the expected 27.75 points. Adherence to SP was associated with the accident report (p < 0.020). Conclusion: We conclude that the proportion/incidence rate of accidents with biological material was high in relation to that in the literature, being higher in professionals and especially among physicians. The levels of knowledge and adherence to SP were good, with the best found in dentists and dental students.

Exploring General and Domain-Specific Cognitive, Motivational and Affective Factors Associated with Excellence and Success in Academic and Sport Contexts: A study with Portuguese Intercollegiate Student-Athletes.

( Manuela Amaral ),( Jose Fernando Cruz ),( Fernando Parente ) 한국체육학회 2015 국제스포츠과학 학술대회 Vol.2015 No.1

Purpose: The study of psychological factors associated with individual success and achievement in major life contexts has been a major goal of research on human excellence. The present study has as main aim the exploration of the role of core cognitive, motivational and affective structures and processes in two major achievement contexts. Another goal was to understand the interrelationships between such psychological constructs (e.g., perfectionism, coping strategies, passion, threat and challenge appraisals) and the perceived competence, as well as the perceived importance of college and sport in Portuguese student-athletes. Method: Participants include 375 Portuguese (43,7% female) student-athletes, with ages ranging between 18 and 37 years-old (M=21,5), from several Portuguese higher education institutions and with different trajectories and levels of success in both domains (academics and sport) , some of them competing at major national and international competitive levels. A "Psychological Assessment Survey" designed for the specific purpose of this project was administered and include general and specific-domain measures in both main domains under study (academic and sport). Result: Psychological differences between successful and non-successful student-athletes in both achievement domains will be explored, with a special emphasis on successful student-athletes in competitive sports at international level. Preliminary analyses (univariate and multivariate), showed that Portuguese successful student-athletes in competitive sport at national and international levels showed higher levels of perceived competence in sport (comparatively to academics), higher levels of sport-specific challenge appraisals and lower levels in some major sport-specific dimensions of perfectionism (e.g., concern with errors, doubts about actions), but also higher levels of general positivity, passion and grit, and problem-solving coping strategies. In addition, a differential pattern of relationships of perceived importance and perceived competence in each specific domain (academics and sport) with different and main psychological factors was evident. Conclusion: The high-stakes "natural" evaluative and the competitive nature of both achievement contexts put additional challenges and "pressures" to student-athletes involved in both competitive sports and academic achievements. Discussion of present results point to the need of solid theoretical foundations for future studies and research on the role of psychological factors associated with excellence and success, but also for the necessary design and implementation of psychosocial interventions with this "forgotten" population of student-athletes in major research programs.

Extracellular and intracellular α-galactosidases were produced by yeast Debaryomyces hansenii UFV-1grown on different media with several carbon sources. D. hansenii grown in YP-medium (1% yeast extract and 2%peptone) presented maximum cell mass (8.45 mg/mL) after 36 h of cultivation, with lactose as carbon source, followed by sucrose, glucose, raffinose, and galactose. Higher extracellular and intracellular α-galactosidases activities were observed at 48 h of D. hansenii cultivation in YPmedium containing galactose (0.97 and 5.27 U/mL) and lactose (1.28 and 4.88 U/mL), supporting the evidence for the model of induction for the yeast GAL/MEL regulon,such as described in Sacharomyces cereviseae.

Animation and Machines: designing expressive robot-human interactions

Joao Paulo Amaral Schlittler(장 파울로 스클리터) 한국만화애니메이션학회 2017 만화애니메이션연구 Vol.- No.49

만화와 종국적으로 애니메이션은 환상적 시나리오 시각화의 효과적인 방법이다. 본고 에서는 어떻게 애니메이션이 미래 현재(변모되어가고 있는 인공두뇌, 매개 사회) 아주 흔한, 그리고 필수불가결한 부분을 차지하게 되었는지 알아볼 것이다. 따라서 애니메이션은 인터페이스이거나 혹은 대변자로서 일시적 형태의 대상인 인간과 현실의 담화형태가 된다. 애니메이션 혹은 특히 애니메이트된 필름은 보통 단편, 실사영화, 픽션이나 논픽션의 캐릭터와 연결되어있다. 하지만 애니메이션은 전통적 영화 형식과 언어와는 거리가 있고 같은 이유로 디자인과 커뮤니케이션 역시 다른 영역으로 구분된다. 하지만 Vilém Flusser에 따르면 그렇지 않다. 같은 전제가 네트워크 문화 속 애니메이션에 적용된다. 애니메이션은 디자인 과정과 제작에 본질(모션 그래픽이나 인터페이스 디자인 그리고 3D 영상작업 등)로 자리한다. 비디오 게임, VR, map 기반 app과 소셜 네트워크 등은 확장된 우주인 우리의 네트워크 기반 문화에 자리하는 것으로 여겨진다. 이러한 것들은 애니메이션과 연결성이 증대된(세계공통어가 디지털 환경 속 멀티-컬처 상호작용에 적용된 것처럼) 디자인 제품과 미디어 훈련이다. 이러한 감각에서 애니메이션은 담론화 되었으며 같은 방법으로 Roland Barthes는 담화 형식의 신화를 묘사한다. 디자인 도구로서의 애니메이션 역할을 탐구하는 목적으로, 제안된 연구는 애니메이션을 사용하여 트렌스 미디어 창작의 이미지 전략을 네러티브와 유저 인터페이스 측면에서 발전시키고자 하는 것이다. Cartoons and consequently animation are an effective way of visualizing futuristic scenarios. Here we look at how animation is becoming ubiquitous and an integral part of this future today: the cybernetic and mediated society that we are being transformed into. Animation therefore becomes a form of speech between humans and this networked reality, either as an interface or as representation that gives temporal form to objects. Animation or specifically animated films usually are associated with character based short and feature films, fiction or nonfiction. However animation is not constricted to traditional cinematic formats and language, the same way that design and communication have become treated as separate fields, however according to Vilém Flusser they aren’t. The same premise can be applied to animation in a networked culture: Animation has become an intrinsic to design processes and products - as in motion graphics, interface design and three-dimensional visualization. Video-games, virtual reality, map based apps and social networks constitute layers of an expanded universe that embodies our network based culture. They are products of design and media disciplines that are increasingly relying on animation as a universal language suited to multi-cultural interactions carried in digital ambients. In this sense animation becomes a discourse, the same way as Roland Barthes describes myth as a type of speech. With the objective of exploring the role of animation as a design tool, the proposed research intends to develop transmedia creative visual strategies using animation both as narrative and as an user interface.

Um autor português do século XIX ainda próximo de nós A novelística de Camilo Castelo Branco

( Maria João Pais Do Amaral ) 한국포르투갈-브라질학회 2005 포르투갈-브라질 연구 Vol.2 No.1

The main purpose of this paper is to present a 19th century Portuguese novelist whose works are not as well known abroad as those of Camões, Pessoa or the Nobel Prize winner Saramago. Nonetheless, he is one of the most representative names of Portuguese Romanticism and, perhaps, one of the most genuine Portuguese writers of all times. Moreover, his works are a precious testimony of Portuguese 19th century’s major historical and social conflicts. Entering Camilo Castelo Branco’s fictional world can, thus, be regarded as one of the best ways of being acquainted with Portuguese history, culture and people. But it’s also a means of having knowledge of an extraordinary story-teller, whose adventurous plots and varied characters representing the worst and the best of mankind attract our attention - anytime, anywhere. The universality of Camilo’s novels partially lies on the fact that, although events take place in Portugal more than one century ago, although characters live and love, struggle and die in a distant country, at a distant time, they are all brought to life by the powerful words of an author who puts them before the reader’s eyes as if they were real people, living nearby or appearing daily on our TV screens. After all, the romantic technique of the feuilleton, which Camilo and most of his contemporary European fellow-writers mastered, is not that different from contemporary TV episodes writing technique. Causing strong feelings and emotions, moving readers or spectators into tears or laughter, sympathy or animadversion, hate or compassion, are crucial ingredients to catch any public’s attention and keep it alive. As a journalist and professional writer, Camilo was well aware of it. That’s why the author never shows indifference towards any character or event of the stories he tells. He makes comments and judgments. He addresses the reader as a friend and leads him to share his points of view. He talks passionately in order to make the reader feel passion. He claims he actually met some of the characters, or witnessed some of the events. For that reason, his autobiographical data also play an important role, as well as contemporary socio-political and historical events. Needless to say, passionate love stories between young people from different social or economical backgrounds constitute the central element of this overwhelming universe, in which individual happiness and collective destinies prove to be inseparable. As a matter of fact, Camilo’s love stories are more than mere love stories because the heroes’ adventures and misfortunes originate in a world where money meant more than human beings and marriage had nothing to do with love. These things are an essential part of the accurate portrayal of Portuguese 19th century bourgeois status that the author depicts in his works, accusing society of being dominated by materialism, prejudice and hypocrisy. Ironically, while suiting the bourgeois readers’ demands, who appreciated adventurous love stories and moral lessons, Camilo went further in his pedagogical labour and pointed his finger at those who made it possible for him to earn a living… And, although he didn’t believe in fiction’s persuasive power, he never stopped praising those things he considered true values: compassion, solidarity, forgiveness, fraternity… in one word, and above all, love. These are the main values his heroes fight for - and also any reader will recognize as the noblest human values.

Príncipes encobertos e princesas enamoradas: do disfarce por amor no teatro de Gil Vicente

Maria João Pais do Amaral 한국 포르투갈-브라질 학회 2008 포르투갈-브라질 연구 Vol.5 No.1

The main object of this essay is love disguise in two plays of Gil Vicente, Portuguese dramatist who developed his theatrical activity between 1502 and 1536 under the patronage of the monarchs Manuel I and João III. Widely spread in 16th century European literature, the motif of love disguise has its origins in chivalry romances, which are one of the many diverse sources of Gil Vicente's court theatre and also one of the dramatist's first spectators' favourite kind of books. I analyse it in Comédia do Viúvo and Tragicomédia de D. Duardos, where the protagonists, princes Rosvel and Duardos, hide their true identity and social rank from their beloved in order to prove the authenticity of their affection. In a first moment, I compare the way each of these two princes uses love disguise, reflecting on the function and meaning of the obvious differences this comparative analysis brings into light. In a second moment, I relate those differences with both the dramatic genre each of these two plays belongs and the conception of love that is on the basis of the stories enacted in Viúvo and Duardos, which, although originating in courtly love conventions, goes far beyond it. Finally, and because Gil Vicente's theatre is an art that strongly depends on circumstances, the date on which these spectacles were presented for the first time before the Portuguese king and court, as well as the purposes they were meant to fulfil, are also taken into consideration in this reflection on the innovative use of love disguise motif by one of the most important Portuguese dramatists of all times.
