Gêneros múltiplos: binarismos versus pluralismo em Stone butch blues e Stella Manhattan

Gêneros múltiplos: binarismos versus pluralismo em Stone Butch Blues e Stella Manhattan almeja discutir a arbitrariedade do sistema de sexo e gênero da sociedade ocidental contemporânea, que categoriza e fixa o sexo biológico dos indivíduos em duas exclusivas expressões de gênero possíveis: homem/masculino x mulher/feminino. Casos em que a referida consonância entre sexo e gênero não ocorre são tratados como aberrações passíveis de punições físicas e morais. O corpus literário desta tese é formado por romances da literatura norte-americana (Stone Butch Blues, de Leslie Feinberg) e brasileira (Stella Manhattan, de Silviano Santiago). A introdução discorre brevemente acerca da história e da teoria do romance, objeto principal deste estudo, posta em prática por renomados romancistas. O segundo capítulo ocupa-se de questões teóricas sobre sexo e gênero, importantes para o embasamento da discussão literária, além da trama e fortuna crítica sobre Stone Butch Blues, incluindo uma análise do autor deste trabalho sobre o referido romance. O terceiro capítulo discute outras questões teóricas, desta vez sobre teoria da Literatura e de gênero, além de apresentar a fortuna crítica de Stella Manhattan, culminando também com uma análise crítica do autor desta tese sobre o romance brasileiro. Ao final da pesquisa, objetiva-se demonstrar que o binário de gênero socialmente imposto precisa, em realidade, ceder espaço a um sistema plural e fluido, no qual a biologia perde seu papel determinante na masculinidade ou feminilidade do indivíduo

Ensaio sobre as imagens. A criação do roteiro de Blindness de Fernando Meireles, adaptado do romance: Ensaio sobre a cegueira de José Saramago para as telas de cinema

A dissertação se propõe a investigar as diferentes formas de estruturas narrativas para o desenvolvimento em um roteiro cinematográfico, adaptado de uma obra literária. Para este trabalho, vamos usar como corpus o romance Ensaio sobre a cegueira de José Saramago que foi adaptado pelo roteirista Don Mckellar, originando o filme dirigido por Fernando Meirelles, em 2008. A finalidade deste recorte é mostrar o processo de construção narrativa no audiovisual, tendo como base o livro. Nessa investigação, o suporte para análise do audiovisual será realizado com conceituados especialistas em roteiros cinematográfico como Linda Hutcheon, Robert Mckee, Jean-Claude Carriére, Flávio de Campos e David Howard. As possibilidades da criação do roteiro seguirão o mote em quatro divisões: narrativa, estrutura, ensaio sobre imagens e da palavra para imagem, procurando responder como a linguagem intervém no sentido da palavra para imagem e como ocorre o conceito de autoria nessa vertente da adaptação. A trama de Ensaio sobre a cegueira, traz elementos clássicos da estrutura dramática e amplia sua dimensão em relação ao conteúdo da estória na roteirização de Don Mckellar. Com esta pesquisa, esperamos contribuir para um melhor entendimento na construção e organização de um roteiro no processo de adaptação em si

Carbon nanotube array: a new MIP platform.

Here we demonstrate that a free-standing carbon nanotube (CNT) array can be used as a large surface area and high porosity 3D platform for molecular imprinted polymer (MIP), especially for surface imprinting. The thickness of polymer grafted around each CNT can be fine-tuned to imprint different sizes of target molecules, and yet it can be thin enough to expose every imprint site to the target molecules in solution without sacrificing the capacity of binding sites. The performance of this new CNT-MIP architecture was first assessed with a caffeine-imprinted polypyrrole (PPy) coating on two types of CNT arrays: sparse and dense CNTs. Real-time pulsed amperometric detection was used to study the rebinding of the caffeine molecules onto these CNT-MIPPy sensors. The dense CNT-MIPPy sensor presented the highest sensitivity, about 15 times better when compared to the conventional thin film, whereas an improvement of 3.6 times was recorded on the sparse CNT. However, due to the small tube-to-tube spacing in the dense CNT array, electrode fouling was observed during the detection of concentrated caffeine in phosphate buffer solution. A new I-V characterization method using pulsed amperometry was introduced to investigate the electrical characterization of these new devices. The resistance value derived from the I-V plot provides insight into the electrical conductivity of the CNT transducer and also the effective surface area for caffeine imprinting.

Baseline assessment of Fish and Coral bays, St. John, U.S. Virgin Islands in support of watershed restoration activities, part I: fish, coral and benthic habitats

This report provides baseline biological data on fishes, corals and habitats in Coral and Fish Bays, St. John, USVI. A similar report with data on nutrients and contaminants in the same bays is planned to be completed in 2013. Data from NOAA’s long-term Caribbean Coral Reef Ecosystem Monitoring program was compiled to provide a baseline assessment of corals, fishes and habitats from 2001 to 2010, data needed to assess the impacts of erosion control projects installed from 2010 to 2011. The baseline data supplement other information collected as part of the USVI Watershed Stabilization Project, a project funded by the American Recovery and Reinvestment Act of 2009 and distributed through the NOAA Restoration Center, but uses data which is not within the scope of ARRA funded work. We present data on 16 ecological indicators of fishes, corals and habitats. These indicators were chosen because of their sensitivity to changes in water quality noted in the scientific literature (e.g., Rogers 1990, Larsen and Webb 2009). We report long-term averages and corresponding standard errors, plot annual averages, map indicator values and list inventories of coral and fish species identified among surveys. Similar data will be needed in the future to make rigorous comparisons and determine the magnitude of any impacts from watershed stabilization.

古田山大样地木本植物根萌现状及优势种群根萌空间格局分析

　　已有研究表明，萌生现象对森林恢复和植被演替等生态过程中具有及其重要的意义，作为一种可以和种子繁殖“抗衡”的直接的再生方式，森林萌生更新已受到越来越多的关注。近年来萌生生态学的研究主要针对于萌生的生态功能如对个体生活史策略的影响、在植被演替中的作用、对物种多样性影响等方面，研究的切入点大多注重相关的环境因子、遗传因子或自然和人为干扰如砍伐、火烧、大风等引起的萌生现象，针对原始森林演替的研究相对较少，针对“长期动态监测样地”的萌生现象则更少。由于长期动态观测样地具有固定和长期观察的特有优点，这对物种共存、格局及维持机制、植被演替等生物多样性热点问题的研究带来了难得的机遇和条件。 我国是地球上亚热带常绿阔叶林分布面积最广，发育最为典型的区域，我国亚热带常绿阔叶林的生物多样性极高,仅次于热带雨林。目前对亚热带常绿阔叶林物种共存、分布格局、群落演替等的研究相对较少。参照美国史密森热带研究所的热带森林研究中心(Center for tropical forest science，CTFS)森林动态样地的操作规范，中国森林生物多样性研究网络在中国从南到北按主要森林类型建立了5块20～25hm2的森林大样地。作为中国森林生物多样性长期监测网络的重要组成部分，古田山样地分布着典型的中亚热带常绿阔叶林。本论文在24hm2古田山中亚热带常绿阔林长期监测样地调查的基础上，重点从古田山大样地木本植物根萌现状及优势种群根萌空间格局等方面进行具体分析，试图了解古田山大样地根萌植物的种类组成、个体大小、数量、地理区系成分特点等基础特征，同时选择大样地乔灌木层的优势树种，重点分析优势种群根萌的空间分布格局及其特点，以便加深了解优势物种根萌的种内、种间的共存关系，也将对优势植物根萌植物的分布和样地生境的关系作出有益尝试。本文最后通过比较优势物种的主干和根萌空间分布格局等方面的相关性进一步揭示根萌在群落组成中的地位和作用。本研究将为亚热带常绿阔叶林根萌植物的长期动态研究积累基础资料，对了解常绿阔叶林根萌植物现状以及空间分布格局等方面起到积极的探索意义，同时对揭示根萌现象在亚热带常绿阔叶林物种多样性维持机制中的地位和作用也将起到一定的推动作用。

Binding of radio-iodinated gonadotropin to the ovary of exotic carp (Cyprinus carpio Lin.)

Heterologous murrel gonadotropic hormone (m-GtH) binds to common carp oocyte plasma membrane and enhances steroid secretion. With increasing concentration of radio-labelled hormone the receptor binding is also found to increase linearly up to a certain concentration and then decrease. The [¹²⁵I] murrel GtH binding characteristics to a preparation of common carp ovarian plasma membrane shows saturability with high affinity. Scat chard plot analysis gave dissociation constant (Kd) of 0.81 X 10(super -9) M and maximum binding capacity (MBC) of 22.05 f mole/mg protein.

Growth parameters of Lepturacanthus savala (Cuvier, 1829) from Mumbai waters

Lepturacanthus savala (Cuvier, 1829) constitutes a minor fishery contributing 23.3% to the total ribbonfish catch in Maharashtra. Based on the length data obtained from shrimp trawlers and the traditionally operated bag nets, age and growth of the species have been investigated from Mumbai waters. Growth was studied by various computer-based methods incorporated in FiSAT Programme. The growth parameters L∞ and K (on annual basis) by Gulland-Holt plot were 683.3 mm and 0.87, respectively. As the seasonal temperature variations in coastal waters of Mumbai are not pronounced, the seasonally oscillating growth patterns by ELEFAN and Appledoorn's method were not considered. Following the von Bertalanffy growth model, the fish attains 399.8, 567.2 and 637.4 mm at the end of 1, 2 and 3 years, respectively, and the lifespan of the fish is about 3.3 years.

Fracture and energy partitioning in uncooked and cooked noodles

Humans perform fascinating science experiments at home on a daily basis when they undertake the modification of natural and naturally-derived materials by a cooking process prior to consumption. The material properties of such foods are of interest to food scientists (texture is often fundamental to food acceptability), oral biologists (foods modulate feeding behavior), anthropologists (cooking is probably as old as the genus Homo and distinguishes us from all other creatures) and dentists (foods interact with tooth and tooth replacement materials). Materials scientists may be interested in the drastic changes in food properties observed over relatively short cooking times. In the current study, the mechanical properties of one of the most common (and oldest at 4,000+ years) foods on earth, the noodle, were examined as a function of cooking time. Two types of noodles were studied, each made from natural materials (wheat flour, salt, alkali and water) by kneading dough and passing them through a pasta-making machine. These were boiled for between 2-14 min and tested at regular intervals from raw to an overcooked state. Cyclic tensile tests at small strain levels were used to examine energy dissipation characteristics. Energy dissipation was >50% per cycle in uncooked noodles, but decreased by an order of magnitude with cooking. Fractional dissipation values remained approximately constant at cooking times greater than 7 min. Overall, a greater effect of cooking was on viscoplastic dissipation characteristics rather than on fracture resistance. The results of the current study plot the evolution of a viscoplastic mixture into an essentially elastic material in the space of 7 minutes and have broad implications for understanding what cooking does to food materials. In particular, they suggest that textural assessment by consumers of the optimally cooked state of food has a definite physical definition. © 2007 Materials Research Society.

Population dynamics and the management of the goat fish Upenaeus sulphureus from the Bay of Bengal

FiSAT program was used to estimate population parameters of Upenaeus sulphureus from length frequency data. Loc and K were found to be 22.7 em and 0.98 year1 respectively. The Wetherall plot provided an estimate of L= and Z/K were 21.585 em and 4.759 respectively. The annual rate of natural and fishing mortality were estimated as 1.91 and 3.86 respectively. The exploitation rate was 0.668. The selection pattern Lc was 10.824 em. Recruitment pattern suggest of two uneven seasonal pulses in March-April and August-October. Peaks appeared in August-October. Maximum yield could be achieved simultaneously increasing length at first capture to 10.0 em. The length weight relationship was found to be W =0.03065 Lz.8328. Highest yield and price could be achieved by decreasing the fishing mortality to 0.9 coefficient rate.

Incremental Linear Discriminant Analysis Using Sufficient Spanning Sets and Its Applications

This paper presents an incremental learning solution for Linear Discriminant Analysis (LDA) and its applications to object recognition problems. We apply the sufficient spanning set approximation in three steps i.e. update for the total scatter matrix, between-class scatter matrix and the projected data matrix, which leads an online solution which closely agrees with the batch solution in accuracy while significantly reducing the computational complexity. The algorithm yields an efficient solution to incremental LDA even when the number of classes as well as the set size is large. The incremental LDA method has been also shown useful for semi-supervised online learning. Label propagation is done by integrating the incremental LDA into an EM framework. The method has been demonstrated in the task of merging large datasets which were collected during MPEG standardization for face image retrieval, face authentication using the BANCA dataset, and object categorisation using the Caltech101 dataset. © 2010 Springer Science+Business Media, LLC.

Development of a universal stress sensor for graphene and carbon fibres

Carbon fibres are a significant volume fraction of modern structural airframes. Embedded into polymer matrices, they provide significant strength and stiffness gains by unit weight compared with competing structural materials. Here we use the Raman G peak to assess the response of carbon fibres to the application of strain, with reference to the response of graphene itself. Our data highlight the predominance of the in-plane graphene properties in all graphitic structures examined. A universal master plot relating the G peak strain sensitivity to tensile modulus of all types of carbon fibres, as well as graphene, is presented. We derive a universal value of - average - phonon shift rate with axial stress of around -5ω0 -1 (cm -1 Mpa-1), where ω0 is the G peak position at zero stress for both graphene and carbon fibre with annular morphology. The use of this for stress measurements in a variety of applications is discussed. © 2011 Macmillan Publishers Limited. All rights reserved.

Investigating the relationships between user capabilities and product demands for older and disabled users

This paper presents the results of a study that specifically looks at the relationships between measured user capabilities and product demands in a sample of older and disabled users. An empirical study was conducted with 19 users performing tasks with four consumer products (a clock-radio, a mobile phone, a blender and a vacuum cleaner). The sensory, cognitive and motor capabilities of each user were measured using objective capability tests. The study yielded a rich dataset comprising capability measures, product demands, outcome measures (task times and errors), and subjective ratings of difficulty. Scatter plots were produced showing quantified product demands on user capabilities, together with subjective ratings of difficulty. The results are analysed in terms of the strength of correlations observed taking into account the limitations of the study sample. Directions for future research are also outlined. © 2011 Springer-Verlag.

Tensile strength properties of polyethylene netting twines under exposure to out-door and artificial UV radiation

Photodegradation of three types of polyethylene twines namely, polyethylene fibrillated tape twine, polyethylene flat tape twine and polyethylene monofilament twines were studied by exposing them to sunlight and artificial UV radiation. The percentage residual strength varied in the samples, the monofilament with the highest residual strength followed by fibrillated tape twine and flat tape twine. A plot of the difference between the breaking strengths of the fibrillated tape twine and the mono filament twines against any given period of exposure exhibited a linear relationship
