Amino acids profile of sugar cane spirit (cachaca), rum, and whisky

An analytical procedure for the separation and quantification of 20 amino acids in cachacas has been developed involving C18 solid phase cleanup, derivatization with o-phthalaldehyde/2-mercaptoethanol, and reverse phase liquid chromatography with fluorescence detection. The detection limit was between 0.0050 (Cys) and 0.25 (Ser) mg L-1, whereas the recovery index varies from 69.5 (Lys) to 100 (Tyr)%. Relative standard deviations vary from 1.39 (Trp) to 13.4 (Glu)% and from 3.08 (Glu) to 13.5 (His) for the repeatability and intermediate precision, respectively. From the quantitative profile of amino acids in 41 cachacas, 5 turns, and 12 whisky samples, the following order of amino acids in significant quantities is observed: Gly = Ser < Cys < Ile < His < Pro = Asp < Asn < Tyr for cachaca; Phe < Glu = Gln = Val = Ala < His = Gly Thr = Arg = Tyr < Asn Ser = Lys = Pro < Cys = Asp for rum; and Ala = Asn < Trp < Gln = His = Met = Ile = Cys < Thr < Asp Leu < Phe = Lys < Ser = Gly = Tyr = Val < Glu = Pro < Arg for whisky samples.

Chemical profile of rums as a function of their origin. The use of chemometric techniques for their identification

To identify chemical descriptors to distinguish Cuban from non-Cuban rums, analyses of 44 samples of rum from 15 different countries are described. To provide the chemical descriptors, analyses of the the mineral fraction, phenolic compounds, caramel, alcohols, acetic acid, ethyl acetate, ketones, and aldehydes were carried out. The analytical data were treated through the following chemometric methods: principal component analysis (PCA), partial least square-discriminate analysis (PLS-DA), and linear discriminate analysis (LDA). These analyses indicated 23 analytes as relevant chemical descriptors for the separation of rums into two distinct groups. The possibility of clustering the rum samples investigated through PCA analysis led to an accumulative percentage of 70.4% in the first three principal components, and isoamyl alcohol, n-propyl alcohol, copper, iron, 2-furfuraldehyde (furfuraldehyde), phenylmethanal (benzaldehyde), epicatechin, and vanillin were used as chemical descriptors. By applying the PLS-DA technique to the whole set of analytical data, the following analytes have been selected as descriptors: acetone, sec-butyl alcohol, isobutyl alcohol, ethyl acetate, methanol, isoamyl alcohol, magnesium, sodium, lead, iron, manganese, copper, zinc, 4-hydroxy3,5-dimethoxybenzaldehyde (syringaldehyde), methaldehyde (formaldehyde), 5-hydroxymethyl-2furfuraldehyde (5-HMF), acetalclehyde, 2-furfuraldehyde, 2-butenal (crotonaldehyde), n-pentanal (valeraldehyde), iso-pentanal (isovaleraldehyde), benzaldehyde, 2,3-butanodione monoxime, acetylacetone, epicatechin, and vanillin. By applying the LIDA technique, a model was developed, and the following analytes were selected as descriptors: ethyl acetate, sec-butyl alcohol, n-propyl alcohol, n-butyl alcohol, isoamyl alcohol, isobutyl alcohol, caramel, catechin, vanillin, epicatechin, manganese, acetalclehyde, 4-hydroxy-3-methoxybenzoic acid, 2-butenal, 4-hydroxy-3,5-dimethoxybenzoic acid, cyclopentanone, acetone, lead, zinc, calcium, barium, strontium, and sodium. This model allowed the discrimination of Cuban rums from the others with 88.2% accuracy.

TR-2015001: A Survey and Critique of Facial Expression Synthesis in Sign Language Animation

Sign language animations can lead to better accessibility of information and services for people who are deaf and have low literacy skills in spoken/written languages. Due to the distinct word-order, syntax, and lexicon of the sign language from the spoken/written language, many deaf people find it difficult to comprehend the text on a computer screen or captions on a television. Animated characters performing sign language in a comprehensible way could make this information accessible. Facial expressions and other non-manual components play an important role in the naturalness and understandability of these animations. Their coordination to the manual signs is crucial for the interpretation of the signed message. Software to advance the support of facial expressions in generation of sign language animation could make this technology more acceptable for deaf people. In this survey, we discuss the challenges in facial expression synthesis and we compare and critique the state of the art projects on generating facial expressions in sign language animations. Beginning with an overview of facial expressions linguistics, sign language animation technologies, and some background on animating facial expressions, a discussion of the search strategy and criteria used to select the five projects that are the primary focus of this survey follows. This survey continues on to introduce the work from the five projects under consideration. Their contributions are compared in terms of support for specific sign language, categories of facial expressions investigated, focus range in the animation generation, use of annotated corpora, input data or hypothesis for their approach, and other factors. Strengths and drawbacks of individual projects are identified in the perspectives above. This survey concludes with our current research focus in this area and future prospects.

The facial affective scale as a predictor for pain unpleasantness when children undergo immunizations.

Needle fear is a common problem in children undergoing immunization. To ensure that the individual child's needs are met during a painful procedure it would be beneficial to be able to predict whether there is a need for extra support. The self-reporting instrument facial affective scale (FAS) could have potential for this purpose. The aim of this study was to evaluate whether the FAS can predict pain unpleasantness in girls undergoing immunization. Girls, aged 11-12 years, reported their expected pain unpleasantness on the FAS at least two weeks before and then experienced pain unpleasantness immediately before each vaccination. The experienced pain unpleasantness during the vaccination was also reported immediately after each immunization. The level of anxiety was similarly assessed during each vaccination and supplemented with stress measures in relation to the procedure in order to assess and evaluate concurrent validity. The results show that the FAS is valid to predict pain unpleasantness in 11-12-year-old girls who undergo immunizations and that it has the potential to be a feasible instrument to identify children who are in need of extra support to cope with immunization. In conclusion, the FAS measurement can facilitate caring interventions.

3D roll-forming of hat-profile with variable depth and width

The use of roll-formed products in automotive, furniture, buildings etc. increases every year due to the low part-production cost and the complicated cross-sections that can be produced. The limitation with roll-forming until recent years is that one could only produce profiles with a constant cross-section in the longitudinal direction. About eight years ago ORTIC AB [1] developed a machine in which it was possible to produce profiles with a variable width (“3D roll-forming”) for the building industry. Experimental equipment was recently built for research and prototyping of profiles with variable cross-section in both width and depth for the automotive industry. The objective with the current study is to investigate the new tooling concept that makes it possible to roll-form hat-profiles, made of ultra high strength steel, with variable cross-section in depth and width. The result shows that it is possible to produce 3D roll-formed profiles with close tolerances.

The Facial Affective Scale (FAS) as a predictor for pain unpleasantness when children undergo immunizations

Needle fear is a common problem in children undergoing immunization.

The Influence of Gender and Facial Appearance on Voting Practices

Women’s faces tend to naturally retain more neonate features than men. These features, such as a greater eye height, a smaller nose area, and a wider smile, would cause women to have more immature faces than males. Interestingly, women who have these facial features are often perceived as more attractive than women with mature facial features. These findings imply that women would be judged less competent than men, and that immature-faced women would be perceived as less competent and more attractive than mature-faced females. Given the direction of political leadership in our country, this has interesting implications for females that are vying for leadership positions. Thus, our study examined the effects of both candidate gender and facial features on voting likelihood, and perceptions of attractiveness and competence, by pairing pictures with neutral party platforms.

Avaliação da aplicabilidade da escala New Involvement Profile para mensuração do envolvimento do consumidor na cidade de Porto Alegre

O estudo do envolvimento do consumidor representa um dos tópicos mais importantes de pesquisa para aqueles que visam entender a forma como os seres humanos realizam suas decisões de compra. O envolvimento determina a quantidade de esforços empregados no processo de tomada de decisão, e apresenta importantes implicações tanto para o âmbito acadêmico quanto para o meio gerencial. No que diz respeito ao ambiente brasileiro, no entanto, foram poucos os trabalhos que se dedicaram exclusivamente a esse tema, não havendo, até o início desta pesquisa, nenhuma escala para mensuração de envolvimento validada para este cenário. O objetivo deste estudo é a avaliação da aplicabilidade da escala de Jain & Srinivasan (1990) na cidade de Porto Alegre. Tal escala, denominada New Involvement Profile (NIP), pode ser utilizada para mensuração do envolvimento de consumidores com diferentes categorias de produtos. Para esta pesquisa, mensurou-se o envolvimento com relação aos produtos cerveja, chocolate, corte de cabelo, CD, aparelho de televisão, detergente, shampoo e pilha. A escala NIP foi reaplicada a uma amostra de 420 (quatrocentos e vinte) respondentes em diversos bairros desta cidade. A qualidade e a robustez da escala de Jain & Srinivasan (1990) foram comprovadas através de testes de confiabilidade e verificações da validade de conteúdo e de constructo, englobando validade convergente e discriminante de cada dimensão da escala. Tal avaliação foi complementada a partir da relação existente entre os níveis de envolvimento encontrados e os pressupostos teóricos acerca desse conceito – tipos e determinates, bem como da comparação entre esses níveis e aqueles obtidos pelos mesmos produtos em estudos semelhantes.

Estudo clínico e bioquímico de 28 pacientes com mucopolissacaridose tipo VI

Realizamos um estudo observacional de pacientes com mucopolissacaridose tipo VI, com o objetivo de determinar o perfil epidemiológico, clínico e bioquímico de um grupo de pacientes sul-americanos a fim de contribuir em estudos futuros de correlação genótipo-fenótipo e de avaliação de protocolos clínicos. Os critérios de inclusão foram: ter 4 anos ou mais e confirmação bioquímica da doença (níveis reduzidos da atividade da ARSB, aumento de GAGs urinários e atividade normal de outra sulfatase). Os critérios de exclusão foram: terapia com reposição enzimática atual ou prévia ou ter realizado transplante de medula óssea. Foram avaliados 28 pacientes por anamnese, exame físico, acocardiograma, eletrocardiograma, avaliação oftalmológica, medidas de glicosaminoglicanos urinários e da atividade da N-acetilgalactosamina-4-sulfatase em leucócitos. A amostra estudada tinha 92,9% de brasileiros, sendo 53,8% da região sudeste. No momento da avaliação, a média de idade foi de 97,1 meses e a média de idade ao diagnóstico foram de 48,4 meses. Em 88% da amostra os sintomas iniciaram com menos de 36 meses e em 27% das famílias houve relato de consangüinidade entre os pais. A média de peso e estatura ao nascimento foi de 3481 gramas e 51,3 centímetros, respectivamente. Da amostra, 57,1% nasceram de parto vaginal. Todos apresentavam alguma alteração ecocardiográfica, bem como opacificação corneana. As manifestações clínicas mais freqüentes foram: baixa estatura, opacificação corneana, facies grosseira, contraturas articulares e mãos em garra. A média da atividade enzimática em leucócitos foi de 5,4 nmoles/h x mg proteína e a excreção urinária de glicosaminoglicanos foi, em média, 7,9 vezes superior ao normal. O número de manifestações clínicas citadas não apresentou correlação significativa com a idade, com a excreção urinária de GAGs ou com a atividade enzimática em leucócitos. Também não houve correlação significativa entre a excreção urinária de GAGS e a atividade enzimática. Concluímos que a MPS VI é uma patologia com alta morbidade e que, comparados com a literatura, os pacientes da nossa amostra têm um diagnóstico tardio e maior freqüência de alterações cardiológicas.

A robust poverty profile for Brazil using multiple data sources

This paper presents a poverty profile for Brazil, based on three different sources of household data for 1996. We use PPV consumption data to estimate poverty and indigence lines. “Contagem” data is used to allow for an unprecedented refinement of the country’s poverty map. Poverty measures and shares are also presented for a wide range of population subgroups, based on the PNAD 1996, with new adjustments for imputed rents and spatial differences in cost of living. Robustness of the profile is verified with respect to different poverty lines, spatial price deflators, and equivalence scales. Overall poverty incidence ranges from 23% with respect to an indigence line to 45% with respect to a more generous poverty line. More importantly, however, poverty is found to vary significantly across regions and city sizes, with rural areas, small and medium towns and the metropolitan peripheries of the North and Northeast regions being poorest.

The Profile of a Manager in Higher Education Institution in Latin America: The Case of the EBAPE

The aim of this study is to analyze the profile of today’s manager, according to the classical management literature, working on internationalized higher education institute. This paper draws together knowledge about the manager’s profile in a corporate environment and how it can be appreciated in a higher education institute all of this taking into consideration the environment that nowadays exists in these institutions. Data were collected through semi-structured interviews, with professors of the Fundacao Getulio Vargas, more specific on their Public and Business Administration School (EBAPE), which had active roles on its development, internationalization and during some point in time their management. The findings obtained where analyzed under the perspective brought by the theoretical reference framework, and, based on this approach is represented the manager whom could have a better perspective to administrate a higher education institute.
