Conservação pós-colheita de diferentes cultivares de mandioca submetidas ao processamento mínimo e congelamento

A demanda dos consumidores por raizes de mandioca de mesa in natura esta decrescendo, em funcao da elevada perecibilidade das mesmas e do aspecto visual pouco atrativo. Como consequencia, vem cres­cendo a comercializacao do produto minimamente processado ou processado na forma de pre-cozido, con­gelado e massa, tanto para o mercado interno como para exportacao. O objetivo do estudo foi determinar a conservacao pos-colheita de raizes de cultivares de mandioca de mesa com coloracao da polpa rosada (BRS 400), amarela (BRS 399) e creme (IAC 576-70), recomendadas para a regiao do Distrito Federal e Entorno, minimamente processadas e acondicionadas em embalagem de polietileno com e sem vacuo, submetidas a refrigeracao e congelamento a -18oC. Durante o armazenamento, foram realizadas analises fisico-quimicas e microbiologicas. O tempo de armazenamento e os tratamentos influenciaram na qualidade das raizes de mandioca minimamente processadas. Considerando as analises microbiologicas, as raizes de mandioca das diferentes cultivares estudadas, minimamente processadas, mantidas congeladas, podem ser comercializadas durante 28 dias em boas condicoes de consumo. Sob refrigeracao com e sem vacuo, a vida util das raizes das diferentes variedades e de, no maximo, sete dias. Raizes de mandioca das cultiva­res BRS 400, BRS 399 e IAC 576-70 nao apresentam variacao significativa na coloracao quando mantidas sob refrigeracao, com e sem vacuo, e congeladas durante 28 dias de armazenamento. As tres variedades de mandioca apresentam maior vida util quando submetidas sob congelamento, sendo uma alternativa para o aumento da vida util de raizes de mandioca minimamente processadas.

Alterations of plasma glutamine and surgical stress in gastric cancer surgery

Background: The plasma glutamine levels are known to decrease after major surgery, which is related to a negative clinical outcome. However, the influence of surgical stress on the decrease in the plasma glutamine concentration is unclear. The aim of this study was to evaluate the change in glutamine in relation to the types of gastrectomy and approaches as well as the amount of surgical stress evaluated by serum interleukin-6(IL-6) as an objective indicator. Methods: This was a prospective observational study. The eligibility criteria were (1) gastric adenocarcinoma of the stomach confirmed by pathology and (2) patients scheduled to receive gastrectomy with lymphadenectomy for gastric cancer. Blood samples were taken at 7 AM on the day of surgery and at 12 h after surgery to measure the plasma glutamine and interleukin-6 (IL-6) levels. Results: Between May 2011 and December 2011, 81 consecutive patients were enrolled in this study. The plasma glutamine level was significantly decreased in all patients, regardless of distal or total gastrectomy and laparoscopic or open surgery. No significant differences were observed in the IL-6 level between total and distal gastrectomy patients or between patients treated via a laparoscopic or open approach. Decreases in the plasma glutamine level were positively correlated with the logarithmically transformed-plasma IL-6 (logIL6) (r =0.471, p<0.001) overall. Conclusions: Decreases in the glutamine concentration depended on the amount of surgical stress. When conducting a clinical trial to evaluate glutamine administration, personalized adjustment may be key to avoiding glutamine depletion in response to surgical stress.
Imaginando a “cidade maravilhosa”: modernidade, espetáculo e espaços urbanos

This essay focuses on the contemporary branding of Rio de Janeiro as a marvelous city. It explores the reinventions of the city for the Olympic event of 2016 by tracing a comparison between the preparations for this mega event and the International Exhibit of the Centenary of Brazil in 1922. It argues that these international events display the desires for an ideal city, the spectacles of modernity and the casting forth of the imaginaries of the media.
ACTIONS AND USES OF DINITROPHENOL: PROMISING METABOLIC APPLICATIONS

We have recently shown in a series of papers1that alpha-dinitrophenol markedly augments metabolism in doses which are not demonstrably harmful. As this drug may have a number of important clinical applications, it seems desirable to present a summary report of its pharmacologic and therapeutic effects, and to point out certain potential dangers in, and limitations to, its use. During the World War, dinitrophenol was called to the attention of French physicians by cases of poisoning from it in munitions factories. Only incomplete investigations of the actions of the compound were made at that time, as judged by published reports. Recently, Magne, Mayer, Plantefol and others2have extended or completed work begun some years previously but reported simultaneously with our entirely independent studies. We are in general agreement with them as to the main pharmacologic actions of the drug. The experimental studies have been extended by us and
Nonlinear behavioral modeling and phase noise evaluation in phase locked loops

In this paper, a method is proposed for evaluating the phase noise spectrum of phase locked loops. Reliable loop simulations are based on a highly-accurate behavioral model for the voltage controlled oscillator. A verification is performed between the output spectrum of the VCO model and the transistor-level VCO spectrum as a function of the applied input voltage. This yields an accuracy better than 0.25 dBc/Hz. The phase noise spectrum of a phase locked loop is calculated. Simulation results are presented and compared with measurements.
Self-Reported Satisfaction with HIV Services Including the AIDS Drug Assistance Program

In this study, we sought to obtain data from HIV/AIDS patients served in Pennsylvania's AIDS Drug Assistance Program (ADAP) in 2005, to obtain input pertaining to the access, utilization, and quality of HIV treatment. Self-reported data through a survey instrument were solicited from all 2912 adults actively enrolled in the Pennsylvania ADAP in 2005. Of the enrollees who responded, 59% reported undetectable viral load, 71% reported CD4 counts of greater than 200 cells/mm3, and 80% reported ease in accessing medical care providers. A positive relationship with clinicians was reported by 93% of respondents, 77% were compliant with treatment, and 87% received timely standard of care. Persons living with HIV/AIDS who were served by Pennsylvania ADAP report higher quality health care, improved health status, improved medication adherence, and lower emergency department/hospital services utilization.
The White Man's Indian

The most obvious explanation for the Native American's Hollywood image is that the producers, directors, and screenwriters and everyone else associated with the movie industry have inherited a long intellectual and artistic tradition. The perceptions that Europeans and Americans have had of the Native American were emotional and contradictory. Either an enemy or a friend, he was never an ordinary human being accepted on his own terms. As Robert Berkhofer explains in his book White Man's Indian: Images of the American Indian from Columbus to the Present (1977), the dominant view of the Indians has always primarily reflected what the white man thought of himself. As the positive concept of the "Noble Savage" took shape, especially in eighteenth century France, it was conceived as evidence to support the arguments of enlightenment philosophers such as Rousseau. Such thinkers believed that people would be better off as children of nature, free of the prejudices and conventions imposed by such established European institutions as the monarchy and the church. The negative view of many of the captivity narratives common in the literature of the New England Puritans proved to the faithful that the forces of the Devil were alive and at work in the dark forests of America. Berkhofer argues that from the first contacts of the European explorers, white men tended to generalize about Indians rather than discriminate,, among individual tribes, to describe Indians primarily in terms of how they differed from whites, and to incorporate strict moral judgements in their descriptions of Indian life. This has proved true in prose, painting, documentary photography—in every art form that chose the Indian as its subject, including film. Consider, for example, the characteristic view of the Indians' relationship to the land. The view—that since the Indian lacked the ambition and good sense that the whites used in developing the American landscape, he impeded progress—has prevailed throughout our history. The movies and television, the popular art forms of today, continue to present images of Native Americans that speak more about the current interests of the dominant culture than they do about the Indians. As war clouds rose overseas in the late 1930s and early 1940s and the dominant American culture sought to reaffirm its traditional patriotic values, the negative stereotype of the Indian (a traditional enemy) served a broader purpose in films such as Drums Along the Mohawk (1939) and They Died With Their Boots On (1941). Thirty years later, with America embroiled in a different kind of war and millions of its citizens challenging the government's policies, the movies reflected its divided
The design and evaluation of a mobile handheld intervention for providing context-sensitive medication reminders

This work introduces the design and exploratory evaluation of a home reminder system for medication and healthcare that situates the timing and location of reminders based on contextual information about the user. The system consists of three major components: 1) a handheld computing interface for providing reminders, 2) a sensor subsystem integrated into the home environment, and 3) a central server that manages medical tasks and reasons over sensor data in real time. A volunteer participant adhering to a complex regimen of simulated medical tasks is closely observed in a residential research facility. The participant is presented with both context-sensitive reminders and reminders that are scheduled at fixed times during the day. The degree of adherence to the regimen, and the participant’s own assessment of the usefulness of each reminder (while blinded to the reminder strategy being used), are evaluated over the course of a 10-day study. Quantitative and qualitative results are provided, comparing the efficacy of context-sensitive reminders over fixed-time reminders with respect to adherence and perceived value.

Towards Operator Monitoring via Brain Reading - An EEG-based Approach for Space Applications

In today’s space applications, astronauts have to perform a variety of tasks. An intelligent on-board monitoring system that ensures uninterrupted, on time monitoring of the astronauts would be a great support. In this paper we want to introduce a new approach for the use of single trial analysis of the human electroencephalogram (EEG) that gives insight into the cognitive state of the operator. This passive monitoring is called brain reading (BR). We discuss the suitability of BR for operator support in space applications regarding the achieved kind and effectiveness of assistance. Further on, solutions for method-depending constraints like the acquisition of training data as well as the the need for software and hardware improvements that will allow the integration of BR in real space applications in the future, are explained.
Building and annotating corpora of spoken Welsh and Gaelic.

The indigenous minority languages of the British Isles and Ireland (or "BIMLs") are becoming increasingly widely used in both public and private life, in some cases within a statutory framework. Speech and language technology applications for these languages are therefore now becoming an urgent need. These are needed not only for monolingual content management, but also to aid translators and interpreters since the BIMLs are nearly always used in bilingual contexts alongside English. To develop such applications, basic language resources (such as corpora of machine-readable texts, machine-readable dictionaries, speech databases and so on) are required.
fMRT der P300: Modifikation der klassischen EEG-Untersuchung für die fMRT

Die Psychiatrie und speziell die Neurophysiologie haben in den letzten Jahrzehnten deutliche Fortschritte in der Erforschung von Entstehungsmechanismen psychiatrischer Erkrankungen gemacht. Mit neurophysiologischen Untersuchungs-methoden wie der EEG konnten zeitliche und raumliche Zusammenhange von neuronalen Aktivierungen aufgedeckt werden. Jedoch stosen die klassischen neurophysiologischen Untersuchungsmethoden bei der Identifizierung von morphologischen Strukturen sehr schnell an die Grenzen ihres Auflosungsvermogens von wenigen Zentimetern. Es liegt nahe, moderne hochauflosende Untersuchungsverfahren wie die MRT einzusetzen, um weitere morphologische Informationen bei der Entstehung von komplexen Nervenzellaktivitaten zu gewinnen. Ziel der vorliegenden Arbeit war es, eine klassische neurophysiologische Untersuchung auf dem Gebiet der Schizophreniediagnostik, namlich die unter standardisierten Bedingungen im EEG abgeleiteten Ereignis-evozierten Potentiale der P300, mit der funktionellen Magnetresonanztomographie (fMRT) zu untersuchen. Es wurde ein spezielles fur die fMRT geeignetes Paradigma, welches sich an dem klassischen EEG-Paradigma orientierte, entwickelt, und an neun gesunden Probanden getestet. Mit Hilfe von intensiven Analysen verschiedener Versuchsaufbauten durch modernste statistische Verfahren konnte schlieslich ein Studienmodell entwickelt werden, das in der Lage war, signifikante Nervenzellaktivierungen in Regionen, die bereits aus der klassischen EEG bekannt sind, hochauflosend darzustellen. Es handelt sich um Aktivierungen im Gyrus supramarginalis, dem Gyrus cinguli und der Insel. Weiterhin wurden Aktivierungen im motorischen Handareal nachgewiesen, die durch gezielte Fingerbewegungen des Probanden im Rahmen des Versuchsparadigma entstanden sind. Die Ergebnisse dieser Arbeit stehen weitgehend im Einklang mit anderen zwischenzeitlich veroffentlichten Studien zu dieser Thematik. Mit Hilfe der Erkenntnisse dieser Arbeit konnten Entwurfe fur zukunftige fMRT-Untersuchungsansatze entwickelt werden, welche teilweise bereits erfolgreich in anderen Studien innerhalb des Instituts untersucht werden.
The multilingual subject : what foreign language learners say about their experience and why it matters

By drawing on multiple examples of real-world language learning situations, this book explores the subjective aspects of the language learning experience. The author encourages readers to consider language learning from new, diverse, and unique perspectives. The book analyses data from a variety of sources, including language memoirs, online data from language learners in chat rooms, and text messaging exchanges. In the analysis of this data, the book looks at the relationship between symbolic form and the development of a multilingual subjectivity; links with memory, emotion, and the imagination; and the implications for language teaching pedagogy.
Computer Science (CS) Education in Elementary Schools: Overcoming obstacles and looking at effective strategies to successful implementation

This qualitative research study looks at the question: how do educators teach complex computer science concepts to elementary students in creative ways and what strategies do they use to engage their students in this field? Two educators who had experience teaching coding to students were approached via convenience sampling to participate in semi-structured interviews. The participants agreed to speak about their experiences, effective strategies, obstacles and benefits of implementing coding in the classroom. These interviews were transcribed, coded and analyzed for common emergent themes to help answer the research question. There were four main themes that emerged in this study: coding in the classroom has a wide range of benefits to students, teachers need many resources and support from staff to carry this work, educators face obstacles regarding lack of knowledge in topic and resources, and lastly to keep consistent with coding integration educators find motivation from their own interest and learning journey. After examining the findings, personal implications and implications for the educational community are discussed and recommendations for teachers, administration and faculties of education are suggested. Finally, further areas of research are suggested that allow for continued possibilities on exploration in coding education.
A Patient-Centered Approach Using Community-Based Paraprofessionals to Improve Self-Management of Type 2 Diabetes

Background Type 2 diabetes is a serious epidemic in our society, which can be prevented or controlled through proper self-management behaviors. Community-based paraprofessionals can serve an important role in forming alliances between health care professionals and patients to enhance self-management practices and improve health outcomes. Purpose The purpose of this study was to examine the impact of a 10-week lifestyle management program delivered by community-based paraprofessionals in improving clinical markers and dietary behaviors related to diabetes control in an underserved population. Methods Michigan State University Extension county offices partnered with local health clinics to identify and recruit participants with physician-identified type 2 diabetes. A research assistant at each clinic introduced the program, obtained consent, and collected baseline and follow-up clinical data (blood pressure, body mass index [BMI], and HbA1c), demographic information, and an assessment of lifestyle behaviors. Results Paired t tests indicated significant changes for: HbA1c (P < .001), BMI (P < .05), smoking tobacco (P < .05), fruit and vegetable intake (P < .01), and appraisal of diabetes scores (P < .001). Discussion These results demonstrate the potential of programs delivered by trained community-based paraprofessionals to improve health outcomes in adults with type 2 diabetes. Translation to Health Education Practice The findings suggest ways in which community organizations can design programs, delivered by trained paraprofessionals, to help address the growing issue of type 2 diabetes.
ASIVA14 : Multi-Rate, MOR and sensitivity in circuit simulation

Faster and smaller electronic devices are more and more required by, e.g., the health care industry, the scientific research community and by the field of entertainment. There is a constant request to increase the simulation speed while keeping a high accuracy and reliability of the simulation. Here, we describe a number of important technical gaps that currently are being addressed within the ASIVA14 project (Analog SImulation and Varability Analysis for 14nm designs).
A Programmer-Centric and Task-Optimized Object Graph Visualizer for Debuggers

Today, existing graph visualizers are not popular for debugging purposes because they are mostly visualization-oriented, rather than task-oriented, implementing general-purpose graph drawing algorithms. The latter explains why prominent integrated development environments still adopt traditional tree views. The authors introduce a debugging assistant with a visualization technique designed to better fit the actual task of defect detection in runtime object networks, while supporting advanced inspection and configuration features. Its design has been centered on the study of the actual programmer needs in the context of the debugging task, emphasizing: 1. ) visualization style inspired by a social networking metaphor enabling easily identify who deploys objects (clients) and whom objects deploy (servers); 2. ) inspection features to easily review object contents and associations and to search content patterns (currently regular expressions only); and 3. ) interactively configurable levels of information detail, supporting off-line inspection and multiple concurrent views.
How do we train a stone to think? A review of machine intelligence and its implications

ABSTRACT Machines have been getting intelligent and they are outpacing humans at certain complex tasks. This paper gives an overview of some of the key technologies used in machine intelligence. We hypothesize that given the future projections in machine capabilities, man–machine symbiosis is a given. Hence, we propose that human learning must be driven to increase the capacity to understand the concepts and apply that knowledge, rather than just memorise the facts or processes. Repetitive human tasks will get automated, freeing us to push the boundaries of creativity and innovation. This will force us to change how we learn and adapt.
Balancing parallelization and asynchronization in event‐driven programs with OpenMP

OpenMP is a popular multiprocessing interface to parallelize different domains of applications. A previously proposed extension has made it possible for OpenMP to speedup event‐driven programs. There, a virtual target model extension is used to incrementally introduce asynchronous execution into an OpenMP program. At the same time it allows a mixture of nested parallelism with asynchronous processing. This new possibility raises the question how to use available processors/threads, for parallelism or for asynchronous execution? To investigate the best combination of asynchronization and parallelization, a performance model for measuring parallel event‐driven systems is proposed. Based on queue theory, the theoretical analysis discovers some interesting facts in an event‐driven system. Then, experiments are conducted to study the best practice of improving event‐driven programs and how to balance parallelism and asynchronous execution. By comparing it with the OpenMP tasking model, the evaluations demonstrate the effectiveness and flexibility of the virtual target model, which is able to achieve significantly better parallel event‐driven performance.
Avaliação de desinfetantes de superfície utilizados em Odontologia

Desinfeccao de superficie e um procedimento realizado nas areas externas do equipamento odontologico e demais itens do consultorio. O objetivo deste trabalho foi analisar a acao de quatro desinfetantes utilizados em Odontologia: alcool etilico a 77°GL, composto fenolico (Duplofen), iodoforo (PVP-I) e solucao de alcool etilico a 77°GL com 5% de clorexidina para desinfeccao de superficie. Foram analisados quatro pontos em cada equipamento ("carter", pia de lavagem de maos, encosto de cabeca da cadeira e superficie frontal externa do refletor), utilizando-se a tecnica de "spray-wipe-spray". De cada ponto, foram coletadas amostras utilizando-se placas de superficie contendo agar Mitis Salivarius bacitracina sacarose, agar Sabouraud Dextrose com cloranfenicol, agar MacConkey e agar-sangue para contagem de estreptococos do grupo mutans, leveduras do genero Candida, bacterias gram-negativas e contagem total de microrganismos, respectivamente (ufc/placa). Os resultados foram analisados estatisticamente utilizando-se teste t de Student para comparacao entre as medias de ufc/placa. O desinfetante que demonstrou ser mais efetivo na reducao microbiana foi a solucao alcoolica de clorexidina, principalmente para bacterias gram-positivas. O iodo e o composto fenolico mostraram ser bastante eficazes na reducao microbiana. O alcool etilico a 77°GL foi o menos eficaz dos quatro desinfetantes analisados, mas apesar de nao ser indicado como desinfetante de superficie, mostrou, no presente trabalho, reducao microbiana estatisticamente significativa apos o processo de desinfeccao.
