description: A cadeia produtiva de lácteos e seus derivados no Brasil vêm apresentando um cenário de profundas mudanças e instabilidade produzindo uma situação de risco e incertezas para todos os membros desta cadeia, incluindo os produtores rurais e a indústria. De um lado da cadeia temos mudanças no setor produtivo, principalmente ocasionado pelos ganhos de produtividade e redução dos preços recebidos; e do outro, mudanças no comportamento do consumidor, principalmente a busca por praticidade e tempo em dicotomia por uma busca de um alimento mais saudável. Surge, então, uma janela de oportunidade e sobrevivência para que as empresas do setor diferenciem os seus produtos. Discriminar e estudar o perfil do consumidor é uma maneira de saber quais as alterações e inovações que devem ser seguidos de acordo com o seu método de produção, característica do produto e logística. Em função dos fatores descritos, este trabalho teve como objetivo traçar clusters (grupos) de comportamento do consumo de produtos lácteos na cidade de Piracicaba-SP. O método escolhido para a formação destes clusters foi a análise de correspondência. A escolha da cidade de Piracicaba-SP foi devida a facilidades logísticas. E a seleção do método foi devido a sua boa aderência para variáveis discretas. ---- The Brazilian dairy sector has been presenting a scenario of great changes and instabilities over the past years, translating in great risks and uncertain for all players, including farmers and the industry. By one si de, there are some changes on the producing sector, the major part as a result of the gains of productivity and retail price reductions; and the other side, changes on consumer behavior (explicitly demands for more practical and easy handling food in dichotomy with health ier and more nutritional food). Emerges a surviving opportunity for the entrepreneur s to create and improve their products. Discriminate and study the consumer prof ile is a path to know which changes and innovations should be made according to it s scope of production (characteristics of production and logistics). For the described factors, this pape r had as the main scope of study built consumers behavior cluster on dairy pr oducts in the city of Piracicaba-SP. The method chosen was the correspondence analysis . The city of Pir acicaba-SP had been chosen due to logistics and the selection of the model was due to good fitness on discrete data.

description: Neste artigo, analisou-se, para o mercado brasileiro, o efeito-fronteira, que indica o viés do comércio doméstico em comparação com o comércio internacional. Esse efeito foi estimado empiricamente, utilizando-se dados de corte seccional, em um modelo de gravidade com os 26 estados brasileiros mais o Distrito Federal e 40 países. Apesar de o Brasil estar reduzindo as barreiras ao comércio internacional, o efeito-fronteira calculado mostrou-se ainda muito alto para os padrões conhecidos. O valor encontrado para o viés entre os estados brasileiros foi igual a 33, evidenciando-se que eles comercializam 33 vezes mais entre si do que com os países estrangeiros. Em um país em desenvolvimento como o Brasil, as conseqüências desse viés, em termos de bem-estar, provavelmente sejam muito grandes. A magnitude do efeito-fronteira pode ser explicada pelo baixo grau de substituição entre os produtos domésticos e estrangeiros e, também, pelas grandes barreiras ao comércio internacional. ---- This paper analyses the border effect in the brazilian goods market, which indicates how biased intra-national trade is compared with international trade. We quantify the border effect empirically using a cross-seccional grav ity equation for twenty six brazilian states plus the Federal District and forty countries , and find that although Brazil has been reducing its trade barriers, the border effect is s till very high to any standards. The bias in a typical brazilian state relative to other count ries was found to be around 33, suggesting that trade among brazilian states is thirty three tim es as high as trade with a foreign country. The welfare consequences of a bias of this size is likely to be very large for a developing country as Brazil. It can be explained both on the low degree of substitutability among goods produced in brazilian states and foreign countries, as well as on the large barriers to trade
title: The mediation in late twentieth-century English theatres of selected ancient Greek tragedy texts and themes concerned with women and power
Creators: name: Hazel, Ruth Mary
Publisher: name: The Open University
Year: 1999

description: This thesis posits a dialogue between ancient Greek and modern English theatres and gives evidence of this dialogue by relating Merent aspects of modem theatre to the recent performance reception in England of specific Greek texts or images which are concerned with women possessed of or by some extraordinary power. Chapter I opens with an account of the aims and scope of the thesis, and discusses some of the problems of translating ancient Greek tragedies onto modem English stages. Each of the following chapters examines some aspect of late twentiethcentury English theatre in relation to its reception through performance of a Greek original text or theme. Chapter 2 deals with changes in English theatre over the last three decades, as reflected by versions of the Bacchae. Chapter 3 is about the role of the actress in performing Medea. Chapter 4 discusses how playwrights have translated for theatre some ancient Greek myths concerning women and sex. Chapter 5 considers the use of Antigone in the field of drama in education, and Chapter 6, the part women theatre practitioners have played in translating Greek drama into English theatres, with special reference to two productions of 'anti-war' plays: the Royal National Theatre's Women of Troy and the Royal Shakespeare Company's The Phoenician Women. The final section of the last chapter reflects on the way the anxieties of male creators and consumers of Greek tragedies about women with power have been interpreted in English theatres, and the importance of the study of reception through performance for scholars working on the original texts.
Lens binarity vs limb darkening in close-impact galactic microlensing events

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Although point caustics harbour a larger potential for measuring the brightness profile of stars during the course of a microlensing event than (line-shaped) fold caustics, the effect of lens binarity significantly limits the achievable accuracy. Therefore, corresponding close-impact events make a less favourable case for limb-darkening measurements than those events that involve fold-caustic passages, from which precision measurements can easily and routinely be obtained. Examples involving later Bulge giants indicate that a ~ 10 % misestimate on the limb-darkening coefficient can result with the assumption of a single-lens model that looks acceptable, unless the precision of the photometric measurements is pushed below the 1 %-level even for these favourable targets. In contrast, measurement uncertainties on the proper motion between lens and source are dominated by the assessment of the angular radius of the source star and remain practically unaffected by lens binarity. Rather than judging the goodness-of-fit by means of a chi^2 test only, run tests provide useful additional information that can lead to the rejection of models and the detection of lens binarity in close-impact microlensing events.

description: Plastic pollution in the aquatic environment has been assessed for many years by ocean waste collection expeditions around the globe or by river sampling. While the total amount of plastic produced worldwide is well documented, the amount of plastic found in the ocean, the distribution of particles on its surface and its evolution over time are still the subject of much debate. In this article, we propose a general fragmentation model, postulating the existence of a critical size below which particle fragmentation becomes extremely unlikely. In the frame of this model, an abundance peak appears for sizes around 1mm, in agreement with real environmental data. Using, in addition, a realistic exponential waste feed to the ocean, we discuss the relative impact of fragmentation and feed rates, and the temporal evolution of microplastics (MP) distribution. New conclusions on the temporal trend of MP pollution are drawn.

description: Esse estudo procurou estimar o efeito doméstico do comércio entre os estados brasileiros, utilizando dados sobre as atividades do setor florestal, de acordo com a classificação nacional de atividades econômicas fiscais (CNAE-F). Para tanto, fez-se uso de um modelo geral de gravidade, que leva em consideração os efeitos das vantagens comparativas advindos das diferentes dotações de fatores. Os resultados encontrados indicam que o tamanho do mercado tem um efeito positivo na razão exportações/importações, com exceção da atividade de silvicultura. O efeito doméstico é maior nas atividades com maior intensidade de capital, apesar de variar entre as diferentes indústrias. A atividade de fabricação de produtos de madeira mostrou-se mão-de-obra intensiva. Os coeficientes estimados permitem classificar as atividades do setor florestal no Brasil, de maneira geral, como intensivas em capital e produzindo bens de necessidade. ---- The goal of this study was to estimate the domestic effect of trade among the Brazilian states, using data on activities of the forest sector, according to the national classification of fiscal economic activities (CNAE-F). To do so, we have used a general gravity model that takes in consideration the effects of comparative advantages coming from differencies in factors endowments. Results indicate that the size of the market has a positive effect in exports/imports ratio, except for the forestation activity. The home market effect is greater on activities intensive in capital, although it varies across industries. The production of wood products was shown to be labor intensive. Based on estimated coefficients, the activities of the forest sector in Brazil, can be classified, in a general way, as capital intensive, producing goods which are necessities in consumption.
Carbon $^{14}$C and Tritium as possible background sources in XENON1T

description: In this work, carbon $^{14}$C and Tritium were considered as possible background source in the XENON1T experiment. The simulation results show that if $^{14}$C is located in dust particles with a characteristic size of tens of micrometers, then its beta spectrum is softened and can contribute to the low-background part of the spectrum (up to 20 keV) of the XENON1T experiment. In addition, it has been shown that the tritium spectrum is also significantly distorted due to the threshold effect and the form in which tritium is living in xenon. Comparison of the simulation results with experimental data allowed us to estimate the activity level of $^{14}$C at about 1500 decays / t / year, which gives the level of organic impurities containing $^{14}$C at the level of 2x10$^{-13}$ g/g. In the case of tritium background, spectrum distortions are already caused by nanoparticles. Wherein the shape of the spectrum from tritium sitting on the surface of the dust fits better into the experimental data than the spectrum from pure tritium. In addition, since the dust absorbs part of the decays, the total amount of tritium in xenon can be several times greater than assuming a background from pure tritium in xenon (the factor strongly depends on the size of the dust particles).

description: A generalized model to study dislocation loops growth in irradiated binary Zr-based alloys is presented. It takes into account temperature effects, efficiencies of loops to absorb point defects dependent on the loop size, an influence of locality of grain boundary sink strength, and concentration of the alloying element. This model is used to describe the dynamics of loop radii growth in zirconium-niobium alloys under neutron irradiation at reactor conditions. A growth of both loop radii and strains is studied at different grain sizes, location from grain boundaries, and concentration of niobium. It is shown that locality of grain boundary sinks results in a non-uniform deformation of the crystal inside the grains. Additionally, an introduction of niobium as an alloying element decreases the loop radii but promotes the growth of local strains inside the grains.

description: We develop a comprehensive theory of phase for finite-dimensional quantum systems. The only physical requirement we impose is that phase is complementary to amplitude. To implement this complementarity we use the notion of mutually unbiased bases, which exist for dimensions that are powers of a prime. For a d-dimensional system (qudit) we explicitly construct d+1 classes of maximally commuting operators, each one consisting of d-1 operators. One of this class consists of diagonal operators that represent amplitudes (or inversions). By the finite Fourier transform, it is mapped onto ladder operators that can be appropriately interpreted as phase variables. We discuss the examples of qubits and qutrits, and show how these results generalize previous approaches.

Pollutant formation in a gaseous-fuelled, direct injection engine
Creators: name: McTaggart-Cowan, Gordon Patrick
Publisher: name: University of British Columbia
Year: 2010

description: Heavy-duty natural gas engines offer air pollution and energy diversity benefits. However, current homogeneous-charge lean-burn engines suffer from impaired efficiency and high unburned fuel emissions. Direct injection offers the potential of diesel-like efficiencies, but requires further research. To improve understanding of the combustion process and pollutant formation mechanisms in a pilot-ignited, direct injection of natural gas engine with intake charge dilution, the effects of enhanced gaseous jet kinetic energy, gaseous fuel composition (including ethane, propane, hydrogen, and nitrogen), and filtering the recirculated gases were studied. An experimental investigation was carried out on a single-cylinder heavy-duty engine. Fuel consumption, in-cylinder performance and gaseous and particulate emissions (total mass, size distributions, and black carbon content) were measured. The results indicated that increasing the jet kinetic energy significantly reduced particulate matter (PM) emissions due to improved fuel-air mixing, especially at high load. The addition of hydrogen to the fuel reduced emissions of carbon monoxide (CO), unburned fuel (HC) and PM. The largest effects were observed at high load conditions. The addition of ethane and propane to the fuel resulted in increases in PM and CO emissions at all operating conditions tested; no effect on the combustion progression was detected. The addition of nitrogen to the fuel significantly reduced emissions of CO, PM, and HC due to enhancement of the late-cycle combustion event from increased in-cylinder turbulence. Removing PM from the recirculated gases revealed that these particles had no significant effect on the combustion event or on PM emissions. In conclusion, mixing and kinetic enhancement both reduced the gaseous fuel ignition delay. The overall combustion event was, at high load, mixing limited; the combustion rate was unaffected by fuel reactivity but was increased with turbulence enhancement. Emissions formation was found to be a result of multiple influences whose relative importance varied with operating condition. Increased mixing and lower fuel carbon content reduced P M emissions. Reductions in emissions through the addition of hydrogen and nitrogen to the fuel may offer a potential technique to offset increases in emissions due to variations in ethane and propane levels in natural gas.

description: The two-pole structure refers to the fact that particular single states in the spectrum as listed in the PDG tables are often two states. The story began with the $Λ(1405)$, when in 2001, using unitarized chiral perturbation theory, it was observed that there are two poles in the complex plane, one close to the $\bar{K}p$ and the other close to the $πΣ$ threshold. This was later understood combining the SU(3) limit and group-theoretical arguments. Different unitarization approaches that all lead to the two-pole structure have been considered in the mean time, showing some spread in the pole positions. This fact is now part of the PDG book, though it is not yet listed in the summary tables. Here, I will discuss the open ends and critically review approaches that can not deal with this issue. In the meson sector some excited charm mesons are good candidates for such a two-pole structure. Next, I consider in detail the $D_0^*(2300)$, that is another candidate for this scenario. Combining lattice QCD with chiral unitary approaches in the finite volume, the precise data of the Hadron Spectrum Collaboration for coupled-channel $Dπ$, $Dη$, $D_s\bar{K}$ scattering in the isospin $I=1/2$ channel indeed reveal its two-pole structure. Further states in the heavy meson sector with $I=1/2$ exhibiting this phenomenon are predicted, especially in the beauty meson sector. I also discuss the relation of these two-pole structures and the possible molecular nature of the states under consideration.

Axial Gravitational Waves in Bianchi I Universe

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this paper, we have studied the propagation of axial gravitational waves in Bianchi I universe using the Regge-Wheeler gauge. In this gauge, there are only two non-zero components of $ h_{μν} $ in the case of axial waves: $h_0(t,r)$ and $h_1(t,r)$. The field equations in absence of matter have been derived both for the unperturbed as well as axially perturbed metric. These field equations are solved simultaneously by assuming the expansion scalar $Θ$ to be proportional to the shear scalar $σ$ (so that $a= b^n$, where $a$, $b$ are the metric coefficients and $n$ is an arbitrary constant), and the wave equation for the perturbation parameter $h_0(t,r)$ have been derived. We used the method of separation of variables to solve for this parameter, and have subsequently determined $h_1(t,r)$. We then discuss a few special cases in order to interpret the results. We find that the anisotropy of the background spacetime is responsible for the damping of the gravitational waves as they propagate through this spacetime. The perturbations depend on the values of the angular momentum $l$. The field equations in the presence of matter reveal that the axially perturbed spacetime leads to perturbations only in the azimuthal velocity of the fluid leaving the matter field undisturbed.

description: Resonances are essential for understanding the interactions between light and matter in photonic systems. The real frequency response of the non-Hermitian systems depends on the complex-valued resonance frequencies, which are the poles of electromagnetic response functions. The zeros of the response functions are often used for designing devices, since the zeros can be located close to the real axis, where they have significant impact on scattering properties. While methods are available to determine the locations of the poles, there is a lack of appropriate approaches to find the zeros in photonic systems. We present an approach to compute poles and zeros based on contour integration of electromagnetic quantities. This also allows to extract sensitivities with respect to geometrical or other parameters enabling efficient device design. The approach is applied to a topical example in nanophotonics, an illuminated metasurface, where the emergence of reflection zeros due to the underlying resonance poles is explored using residue-based modal expansions. The generality and simplicity of the theory allows straightforward transfer to other areas of physics. We expect that easy access to zeros will enable new computer-aided design methods in photonics and other fields.

description: O processo inflacionário brasileiro foi estudado a fundo por dois principais grupos de estudiosos: o tradicional monetarista e o estruturalista. O primeiro acreditava que o processo inflacionário fosse resultado do crescimento mais acelerado da oferta que da demanda monetária, dada a incapacidade do governo de cobrir seus gastos com tributos e emissão de títulos; já o segundo grupo julgava que a inflação fosse uma conseqüência do padrão de desenvolvimento via promoção do setor industrial, em outras palavras, o setor agrícola era visto como propagador de inflação, levando-se em conta que o crescimento rápido da demanda de produtos agrícolas tinha uma resposta inadequada à oferta desses produtos. Esta teoria foi utilizada neste trabalho. Diante desses questionamentos elaborou-se este trabalho com o objetivo de investigar se os produtos agrícolas são ou não potencialmente inflacionários após a estabilização econômica proporcionada pelo Plano Real, verificando ainda, qual participação dos preços agrícolas e preços industriais na formação do índice geral de preços. Este trabalho compara seus resultados com os obtidos na dissertação de Abdallhah (1991) que utilizou o modelo de Modiano (1985) de determinação simultânea de salários e preços na economia onde se verificou que os preços industriais influenciavam mais na formação dos preços globais que os preços agrícolas. Neste trabalho, utilizou-se o modelo dinâmico de defasagem distribuída pelo fato deste descrever melhor a evolução da economia e suas reações encadeadas ao longo do tempo. As séries em estudo passaram por dois testes de raiz unitária: Dickey e Fuller Aumentado (ADF) e o teste Kwiatkowski, Phillips, Schmidt e Shin (KPSS) a fim de evitar resultados espúrios. Foi realizado, ainda, o teste Wald para avaliar o grau da transmissão dos índices inflacionários

description: Market price cointegration is a critical issue in Nepalese vegetable industry. This study intended to analyze the market price cointegration of tomato and its effect on Nepalese farmers, using secondary monthly time series of wholesale price data (since 2000 to 2010) of the Government of Nepal. The results of error correction model (ECM) showed that the series were stationary, and Kathmandu market was well cointegrated with source markets (Chitwan and Morang). Meanwhile, the vector error correction model (VECM) revealed that price adjustment process was much faster in source markets especially in negative price shocks in response to Kathmandu market, which affected the farmers for speedy price adjustment that leads to be hurt and discouraged. The study recommend policies to establish alternative vegetable markets that reduce the price dependency of farmers on Kathmandu market, encourage traders in involving vegetable marketing, and enhance effective market information services.

description: Interspacecraft ranging is crucial for the suppression of laser frequency noise via time-delay interferometry (TDI). So far, the effects of on-board delays and ambiguities on the LISA ranging observables were neglected in LISA modelling and data processing investigations. In reality, on-board delays cause offsets and timestamping delays in the LISA measurements, and pseudo-random noise (PRN) ranging is ambiguous, as it only determines the range up to an integer multiple of the PRN code length. In this article, we identify the four LISA ranging observables: PRN ranging, the sideband beatnotes at the interspacecraft interferometer, TDI ranging, and ground-based observations. We derive their observation equations in the presence of on-board delays, noise, and ambiguities. We then propose a three-stage ranging sensor fusion to combine these observables in order to gain accurate and precise ranging estimates. We propose to calibrate the on-board delays on ground and to compensate the associated offsets and timestamping delays in an initial data treatment (stage 1). We identify the ranging-related routines, which need to run continuously during operation (stage 2), and implement them numerically. Essentially, this involves the reduction of ranging noise, for which we develop a Kalman filter combining the PRN ranging and the sideband beatnotes. We further implement crosschecks for the PRN ranging ambiguities and offsets (stage 3). We show that both ground-based observations and TDI ranging can be used to resolve the PRN ranging ambiguities. Moreover, we apply TDI ranging to estimate the PRN ranging offsets.

description: Spin torque oscillators are conventionally described by the Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation. However, at the onset of oscillations, the predictions of the conventional LLGS equation differ qualitatively from experimental results and thus appear to be incomplete. In this work we show that taking charge conservation into account leads to a previously-overlooked self-induced torque, which modifies the LLGS equation. We show that the self-induced torque originates from the pumping current that a precessing magnetization drives through a magnetic tunnel junction. To illustrate the importance of the self-induced torque, we consider an in-plane magnetized nanopillar, where it gives clear qualitative corrections to the conventional LLGS description.

description: The world experienced in dramatic price surge of food commodities since mid of 2007 to 2008. It was claimed that the crisis were being mainly for backdrop of global shocks in food and energy price. But how the shocks come to domestic market from external sources is a researchable phenomenon. Surprisingly few attempts have been made to systematically analysis of shock transmission from international to domestic market. The study analyzed the effect of global commodity market factors and domestic exchange rate development on domestic food price in Bangladesh. A bi-variants co-integration approach was applied for the analysis of shock transmission. Finally an error correction model was developed. The overall magnitudes of the pass through suggest that only 46 per cent of the total world shock pass-through in domestic economy.

description: The purposes of this study is at analyzing the impact of maize import tariff policy changes on production and consumption in Indonesia. Three groups of households were assessed in this studi, namely: (1) large scale broiler farming, (2) small scale broiler farming, and (3) other households. Employed data in this study were classified into 3 types: (1) production and input, consumption, and household income, (2) inputs and outputs, and (3) elasticities. The abolishment of the import tariff policy on maize had an impact on increased maize imported and decreased maize price. Decreased domestic maize price was responded by maize farmer through lessing maize planted area and fertilizer input uses that had impact on the declining in maize production. On the other hand, this policy had positive impact on production of rice, chicken meat, and eggs which led to increase incomes of small scale broiler farming and agricultural sector, as well as national. It furthermore increased the consumption for maize, chicken meat, and eggs in Indonesia.

description: This study focuses on food label use by Nigerians, using Kwara State as a case study. Specifically, the study describes the socio-economics characteristics of the respondents, determined people’s perception about food labels and examined factors influencing willingness-to-read food labels in the study area. A total of 120 respondents selected through a combination of purposive and random sampling techniques were used for the study. Data were analyzed with descriptive statistics, 5-point likert scale and logistic resgression analysis. Majority of the respondents were females (72.5%), married (60%) and had secondary education (50%). The mean age, household size, number of preschool children and household income of the respondents were 26years, 9 persons, 2 children and N25,250.00/month (USD 157.81) respectively. The respondents opined that food labels were used mainly for traceability (M = 3.24), registration status of the food producer (M = 3.01), advertisement (M =4.02), as a legal requirement (M = 4.00), to know the expiry dates (M = 4.57) and to distinguish the product from that of other competitors (M = 3.54). Results of the regression analysis revealed that women were more willing to read food labels than men, and positively related to age of respondent, household income level, educational status of food planner and nutritional knowledge of the food planner. However, willingness-to-read food labels by the respondents declined with household size and number of preschool children. The study therefore calls for enlightenment of the public by relevant stakeholders on importance of food labels to determine nutritional composition and health implications.

description: The paper stresses on understanding factors affecting development of citrus industry in Tanzania particularly in Muheza District, in Tanga region. Citrus fruit is one of the most important crops in Muheza District of Tanga region in Tanzania particularly in improving rural farmers’ income. The study employed institutional framework methodology. The study disclosed that the government of Tanzania has been implementing various agricultural development programmes in improving citrus fruit production as well as to enhance farmers’ income. However, yet the results reveal that the citrus farming practices in the surveyed area are not well developed. And these are because citruses are still grown under rain fed regime without any form of irrigation, citrus seedlings are produced by individual farmers locally in their backyard nurseries. There is no professional company responsible for seedling production. Also, citrus farmers’ skills in citrus husbandry practices are limited. Lastly, all citrus varieties used contain many seeds in the citrus fruits whereas the market demands seedless citrus fruits. It is therefore, recommended that the policy maker should focus on development of citrus industry in Tanzania using proper institutional framework support, which could increase growth and development of citrus production through the provision of subsides for inputs to reduce cost of production and enlightenment campaigns to improve farmer’s knowledge and technical skills on how to reach lucrative markets.
