The traditional wood used to make barrels destined for use in the world wide wine industry is oak. However, oak chips and shavings can substitute for barrels to add flavour to wine and are very much more cost effective. As with the heat treatment of barrels, oak chips are toasted before use. This serves to pyrolyse lignin and hemicellulose, generating families of compounds that impart desirable flavours to wine. Other woods are very occasionally used in wine barrel construction, but no chips other than oak chips have been used to flavour wine. This is surprising given that all woods contain lignin and hemicellulose, the composition of which will vary perhaps usefully from species to species. The 12 woods used in this research, including American oak, were chosen on several criteria: botanical similarly to oak, exclusivity to New Zealand, and historical association with New Zealand. The woods were cut to chips measuring about 10 x 20 x 2.5 mm. The moisture content was measured after dry heating to 110°C. Fresh samples of chips were heated (toasting in the context of wine) to 200°C for 2 hours, 210°C for 3 hours, called light and heavy toasting respectively. Weight loss was determined. The colour of the untreated and toasted wood chips was measured in Hunter colour space, yielding data on lightness (L*), hue angle (the basic colour) and saturation (the intensity of colour). The moisture content of oak was the lowest of all the woods. The weight loss of oak chips at 200°C was much greater than that of other woods, but the colour change did not indicate losses due to severe charring. Overall, each wood behaved in a distinctive way to the toasting treatments, with some charring much more than others. Hue was the least affected, indicating that the basic colour of the woods was little changed by toasting. Light and saturation generally decreased strongly, particularly on heavy toasting. Colour was thus being lost and less light reflected. An unoaked chardonnay was infused with toasted chips at the rate of 5 g.L-1 for two weeks at room temperature, and later decanted. At all stages exposure to air was minimised. The 25 treatments (2 x 12 plus the unwooded control) were first assessed by a panel comprising eight experienced wine tasters and 29 AUT staff members who claimed some knowledge of wine flavour. This qualitative/semi-quantitative analysis required tasters to assess the wines in terms of 12 descriptors commonly associated with oaked wines (boxes were ticked for ‘sweet oak’, ‘smokey’, ‘vanilla’ etc.), and to choose the three most liked and the three least liked. 6 Confidential A principal component analysis of a correlation matrix of descriptors was used to summarise panelist’s opinion. The first two principal components explained 53 % of the variation and served to group descriptors into four quadrants, which were each associated with different woods and toasting levels. Most liked were totara light (toast), kahikatea heavy, manuka heavy and American oak light. Macrocarpa light toast was almost universally disliked. On the basis of liking and association with New Zealand, five woods and chosen toasting levels and the control were selected for hedonic trials (1 to 9 liking scale) with 180 consumers (age range and gender were identified) in six retail wine shops. The decreasing numerical of liking by treatment was totara (6.49), control, manuka, American oak, kahikatea, radiata pine (5.47), with an overall significant effect (P < 0.001) for treatment. Tukey’s test revealed that only totara and the control treatments were outstanding (P < 0.05). Retail wine shop as a factor was marginally significant. Older consumers liked the wines more (P < 0.05), as did females (P < 0.001). There were no significant interactions between any of the factors. Because of the difficulties in sourcing totara, manuka appears to be the most viable alternative to oak as a wine flavouring in the New Zealand context.

A partir de valores individuais de resistência à compressão paralela de corpos de prova de uma amostra representativa do lote de madeira, a resistência característica é avaliada com estimador específico, proposto pela NBR 7190 (ABNT, 1997). Com o valor da resistência característica, o lote de madeira é classificado em classes de resistência (três classes distintas para madeiras de coníferas e quatro classes distintas para madeira de folhosas) que variam de 20 MPa a 60 MPa. Lotes de madeira com maior valor de resistência característica levam, na maioria das vezes, à otimização dos projetos estruturais. O objetivo principal deste trabalho foi avaliar a eficiência de vários estimadores da resistência característica de lotes de madeira de distintas procedências, gêneses e idades das árvores, com base em suas aplicações em amostras de diferentes tamanhos amostrais. Para o estudo foram utilizados lotes de resultados de resistência mecânica da madeira de diversos conjuntos de dados, abrangendo resistências à compressão paralela às fibras e resistências ao cisalhamento de madeiras nativas e de reflorestamento, coníferas e folhosas. Com uso do software estatístico SAS, para cada lote sortearam-se repetidamente amostras, variando-se os tamanhos amostrais e, a partir dos valores de resistência dos indivíduos de cada amostra foram calculadas as resistências características dos lotes. Tomando-se a resistência característica do lote (aqui assumido como população) como referencial, foi avaliada comparativamente a eficiência de cada estimador, com base no erro quadrático médio e no desvio da estimativa. 2 Os resultados mostraram que o estimador... / In Brazil, lumber classification for structural purposes is based on its characteristic strength in compression parallel to grain. From individual values of strength in compression parallel obtained from specimens of a sample, characteristic strength is evaluated with a particular estimator proposed by the standard NBR 7190 - Design of wood structures (ABNT, 1997) for general usage (all the mechanical properties). With this characteristic strength, lumber lot is classified into classes of strength (three different classes of coniferous woods and four different classes for hardwood) ranging from 20 MPa to 60 MPa. Lumber lots with higher characteristic strength leads, in general, to a design optimization. The main objective of this study was to evaluate the efficiency of several estimators of characteristic strength of lumber lots with distinct origin, genesis and ages, based on their application in samples with different size. Lots of results of strength in compression and in shear parallel to grain of conifers and hardwood from native and reforested plantation were used. Using SAS - Statistical Analysis System - specimens were randomly sampled from each lot - varying sample size from 6 to 42 specimens - from which the characteristic strength of the lot was calculated each time based on the estimators. Taking as referential the characteristic strength of the full lot (assumed as the population), comparative efficiency of the estimators were analyzed based on MSE (mean squared error) and deviation of the estimation. Results showed that the estimator proposed by NBR 7190(ABNT, 1997) was not the more efficient in all cases. For compression and shear parallel to grain, best estimations of characteristic strength were obtained with the estimator that uses lots central tendency and dispersion parameters in its formulation...

A maturação em tonéis de carvalho é uma prática importante amplamente empregada na produção de uma bebida de alta qualidade. Porém, apesar da biodiversidade no Brasil, o envelhecimento da cachaça em tonéis de madeira não é uma prática comum. Os tonéis de carvalho são usualmente mais empregados para o processo de maturação da cachaça. Estes tonéis foram usados previamente por produtores para maturação de vinho, conhaque, e envelhecimento de whisky na Europa e América do Norte. Os apontamentos de alternativa para o carvalho apresentados neste trabalho reportam o perfil fenólico dos extratos de cachaça de espécies de madeira brasileiras em comparação com o carvalho. O método de HPLC foi usado para a análise simultânea de 16 compostos fenólicos de relevância para o sabor e aroma de bebidas envelhecidas. As separações cromatográficas foram realizadas usando uma coluna Shimadzu de C18 (2 mm x 3&#956;m x 250 mm) com gradiente de eluição. As eluições dos compostos foram monitoradas em seu máximo de absorção especifico através de um espectrofotômetro de arranjo de diodo com exceção de catequina e epicatequina, as quais foram monitoradas usando um detector espectrofluorométrico com emissão fixada a 280 nm e excitação a 313 nm. Os 16 compostos fenólicos seguintes foram analisados: (ácido gálico, (+)catequina, ácido vanílico, vanilina, (-)epicatequina, ácido seríngico, seringaldeído, escopoletina, cumarina, sinapaldeído, coniferaldeído, trans-resveratrol, ácido elágico, mirecetina, quercetina e o eugenol) em extratos de cachaça de diferentes espécies de madeira. Os principais compostos fenólicos identificados e quantificados foram: ácido de vanílico (média 0.18 mg/L), seringaldeído (média 0.048 mg/L) e vanilina (média 0.47 mg/L). A cumarina apresenta maior concentração nos extratos de madeira brasileira do que nos extratos de carvalho nos níveis do composto supracitado. Nas amostras de carvalho o teor médio foi de 0,0054 mg/L e nas espécies de madeira brasileiras o teor médio foi de 1,2 mg/L. Também foi analisada a presença de compostos fenólicos em cachaça, rum e whisky onde o seringaldeído e a vanilina foram os compostos majoritários. / Maturation in oak barrels is an important widely spread pratice in the production of a high quality spirit. However, despite the biodiversity in Brazil, the cachaça aging in wodden barrels is not a commun pratice. The use mostly imported oak barrels for the cachaça maturation process. This producers barrel had been usual maturation previously for wine, cognac, and whisky aging in Europe and North America. The aiming to present alternative to oak the present work report the phenolics profile of cachaça extracts of Brazilian wood species in comparation with oak. A HPLC method was used for the simultaneous analysis of 16 phenolic compounds of importance for the flavor and aroma of aged spirits. The chromatographic separations were carried out using a Shimadzu C18 column (2 mm x 3&#956;m x 250 mm) with for elution gradient. The eluting compounds were monitored at their specific maximum of absorption through a diode array spectrophotometric detector with exception of catechin and epicatechin which were probed using a spectrofluorometric detector with emission set at 280 nm and excitation at 313 nm. Follow 16 phenolics compounds have been analisys: ( gallic acid, (+)cathechin, vanillic acid, vanilin, (-)epicathechin, seringic acid, seringaldehyde, escopoletin, coumarin, sinapaldehyde, coniferaldehyde, trans-resveratrol, ellagic acid, mirecetin, quercetin and the eugenol) in cachaça extracts of different wood species. The major phenolic compounds identified and quantified are vanillc acid (medium 0.18 mg/L), seringaldehyde (medium 0.048 mg/L) and vanillin (medium 0.47 mg/L).

WINNICOTT para uma teoria do desenyolvimento emocional do bebê e da criança em seus primeiros anos de vida. A teoria de WINNICOTT, seguindo dois caminhos paralelos e que frequentemente se intercruzam, estuda. de um lado, o crescimento emocional do lactente e, de outro, as qualidades da mãe. suas mudanças e o cuidado materno que satisfaz as necessidades específicas do lactente. A presente dissertaçâo é dividida em uma introdução, quatro capítulos e um epílogo. Utilizou-se. do conjunto da obra winnicottiana. corno fonte primária pesquisada, mas nâo se aventurou em uma análise epistemológica da mesma. Na introdução. retrata-se em linhas gerais, o homem e o clínico D. W. WINNICOTT que, tendo trabalhado como pediatra, chegou à psicanálise. Assim através de um diálogo constante entre estas duas influências principais. elaborou sua contribuiçâo teórica a uma grande variedade de temas, que sempre tiveram presentes o estudo do desenvolvimento emocional do bebê em seus estádios mais precoces e o papel que o cuidado materno desempenha nesse período. O capítulo I relata a jornada do ladente desde o período de dependência absoluta, passando por um período de dependência relativa, para finalmente chegar à independência ou autonomia, que nunca é absoluta. Para WINNICOTT essa jornada só se torna possível em virtude do reconhecimento que a mãe tem da dependência do bebê nos períodos iniciais do seu desenvolvimento. Isto faz com que a mãe corresponda às necessidades egóicas e instintivas do lactente, adaptando-se quase que perfeitamente a ela e criando um "setting", que \VINNICOTT denominou "ambiente de facilitação" - , permitindo que os "processos de maturação" do bebê possam se revelar através de um impulso para a integraçâo e para o desenvolvimento de um self pessoal e real. O capítulo lI, descreve os primórdios do desenvolvimento emocional primitivo, durante o período de dependência absoluta. quando o bebê está em um estado de fusão com a mãe. Centralizando-se no estudo de desenvolvimento do ego, que vivencia uma "continuidade de ser" , graças a um bom cuidado materno, três são as realizações principais expostas neste capítulo: a - integração, isto é, o bebê adquire um status de unida.de; b -personalização ou inserção psicossomática, permitindo que o bebê sinta-se habitando o próprio corpo e que possibilita que a da pele, como membrana, passe a delimitar um interior e um exterior; c - início das relações objetais ¿Observação: O resumo, na íntegra poderá ser visualizado no texto completo da tese digital. / Abstract: The objective of this dissertation is to organize the contributions of D.W.WINNICOTT, paediatrician, child psychiatrist and psychoanalyst to the theory of emotional developmeni of the infant and the child during the first years of life. Following two parallel and frequently crossing paths, WINNICOTT'S theory studies on the one hand the emotiona] growth of the infant, and on the other, the mother's qualities, the changes in these qualities and the maternal care which satisfies the specific needs of the infant. This dissertation is divided as follows: introduction, four chapters and an epilogue. The author used the complete works of W1NNICOTT as the primary source of research. but did not attempt an epistemological analysis of thc aforesaid. In the introduction the author presents a brief overall view of D. W. W1NNICOTT the man and the clinician. who arrived at psychoanalysis through his work as a paediatrician. In this way, by means of a constant dialogue between these two principaJ infll1ences. he made his theoretical contributions to a great variety of subjects alI of which contained the study of the emotional growth of the infant in its earliest stages and the role played by maternal care during this period. Chapter one describes the infant's journey from the period of absolute dependence. followed by a period of relative dependence, arriving finally at independence or alltonomy, which is never absolute. For WINNICOTT this journey is only made possible by the mother's knowledge of theinfant's dependence during the initial stages of development. This allows the mother to correspond to the ego-needs and instinctual needs of the infant, adapting almost perfectly to them and creating a setting which WINNICOTT termed environment provision, thus permitting the maturational processes of the baby to be revealed through an impulse for integration and for the development of a personal and real self. In chapter II the author describes the beginnings of primitive emotional development during the total independence period when the infant is in a state of being merged in with the mother. Concentrating on the study of ego development where a continuity of being is experienced, due to good-enough maternal care, there are three main realizations shown in the chapter a) integration, that is, the infant acquires the status of being a unit b) personalization or psychosomatic insertion which allows the baby to feel himself living inside his own body and which makes it possible to equate the skin as a membrane which delimits an interior and an exterior c) initiation of object-relating ...Note: The complete abstract is available with the full electronic digital thesis or dissertations. / Mestrado / Mestre em Ciências Médicas

The thesis analyzes how IMFs operations transformed as the changes took place in the global economy after world war two. Policy and means used by IMF to achieve its purposes are examined focusing on their effectiveness. The analysis illustrates an apparent change in the role the institution is playing in the global economy. In the first three decades after the world war two the IMFs key role was to maintain surveillance over the rules of the monetary system established at international financial conference in Bretton Woods. The introduction of floating exchange rate systems in developed countries, oil crisis and independence of many African countries caused a shift in IMFs main focus towards developing countries, long-term financing and technical assistance. The analysis concludes that the institution was only in part successful in its mission to maintain global economic stability only in part. In the nineties it reacted promptly to financial crisis by introduction of new facilities and by activating in coordination with other global players of large financial support for the affected countries. However in the period before the financial crisis occurred more attention IMF should have given more attention to precautionary measures eliminating the risks associated with capital volatility.

In this thesis, I document the ideas behind and my process for Play in the Woods, an experiment in slow theater-making that serves as a model for how dramaturgs can facilitate sustainable, holistic methods of performance. This model is grounded in feminist theater practices and the aesthetic of poor theater. In creating the performance of Play in the Woods, I as dramaturg invited participants to serve as co-creators, individually crafting pieces that examined fairytales and the role those stories have played on their lives. The performance was held out of doors at the Amethyst Brook Conservation Area on the afternoon of May 5th, 2018. This framework allowed for an examination of the role of childhood and memory, as well as space, place, and the natural world, on my and the other performers’ sense of self in light of our personal and cultural influences.

Thesis (Ph. D.)--Joint Program in Oceanography (Massachusetts Institute of Technology, Dept. of Biology; and the Woods Hole Oceanographic Institution), 2007. / Includes bibliographical references. / Marine mammals possess high body burdens of persistent organic pollutants, including PCBs and dioxin-like compounds (DLC). Chronic environmental or dietary exposure to these chemicals can disrupt the function of reproductive and immune systems, as well as cause developmental defects in laboratory animals. The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor, mediating the expression of a suite of genes in response to exposure to DLC and structurally related chemicals. Species-specific differences in AHR structure can affect an organism's susceptibility to the effects of DLC. The structures and functions of several cetacean AHRs were investigated using in vitro molecular cloning and biochemical techniques. Using a novel combination of remote biopsy and molecular cloning methods, RNA was extracted from small integument samples from living North Atlantic right whales to identify the cDNA sequence for AHR and other genes of physiological importance. Biopsy-derived RNA was found to be of higher quality than RNA extracted from stranded cetaceans, and proved a good source for identifying cDNA sequences for expressed genes. / (cont.) The molecular sequences, binding constants, and transcriptional activities for North Atlantic right whale and humpback whale AHRs cDNAs were determined using in vitro and cell culture methods. Whale AHRs are capable of specifically binding dioxin and initiating transcription of reporter genes. The properties of these AHRs were compared with those from other mammalian species, including human, mouse, hamster, and guinea pig, and other novel marine mammal AHRs, using biochemical, phylogenetic, and homology modeling analyses. The relative binding affinities for some marine mammal AHRs fall between those for the high-affinity mouse AHRb-1 and the lower affinity human AHR. Species-specific variability in two regions of the AHR ligand binding domain were identified as having the greatest potential impact on AHR tertiary structure, yet does not sufficiently explain differences observed in ligand binding assays. Additional studies are necessary to link exposure to environmental contaminants with potential reproductive effects in marine mammals, especially via interactions with steroid hormone receptor pathways. / by Joy M.
