description: After outlining some relevant background information about the NT crocodile farming industry and explaining the purpose of our survey of NT crocodile farmers conducted in the first half of 2005, this paper reports the results of the survey. The information received from the survey is supplemented by secondary data and by information from secondary sources. This report covers the location of respondents; the size of crocodile farms; farmers’ stated knowledge of and attitudes towards the NT Crocodile Management Plan; the involvement of farms in the harvesting of crocodile eggs and the costs involved; views of crocodile farmers about whether the NT Crocodile Management Plan encourages landholders to conserve crocodiles and their perceptions of the benefits to landholders; predicted production trends and trends in the number of farms operating in NT; economic characteristics of crocodile farms producing in NT including the economic advantages and disadvantages of crocodile farming in NT. Concluding comments provide, amongst other things, an overview of the structure of the crocodile farming industry in the NT gleaned from a consideration of data available from the NT Government’s Department of Business, Industry and Resource Development.

description: We study the spectrum and OPE coefficients of the three-dimensional critical O(2) model, using four-point functions of the leading scalars with charges 0, 1, and 2 ($s$, $ϕ$, and $t$). We obtain numerical predictions for low-twist OPE data in several charge sectors using the extremal functional method. We compare the results to analytical estimates using the Lorentzian inversion formula and a small amount of numerical input. We find agreement between the analytic and numerical predictions. We also give evidence that certain scalar operators lie on double-twist Regge trajectories and obtain estimates for the leading Regge intercepts of the O(2) model.

description: Environmental conditions play a significant role in the economic success of aquaculture. This article classifies environmental factors in a way that facilitates economic analysis of their implications for the selection of aquaculture species and systems. The implication of on-farm as on-site environmental conditions for this selection are considered first using profit-possibility frontiers and taking into account the biological law of environmental tolerance. However, in selecting, recommending and developing aquaculture species and systems, it is often unrealistic to assume the degree of managerial efficiency implied by the profit-possibility function. It is appropriate to take account of the degree of managerial inefficiency that actually exists, not all of which may be capable of being eliminated. Furthermore, experimental R&D should be geared to on-farm conditions, and the variability of these conditions needs to be taken into account. Particularly in shared water bodies, environmental spillovers between aquaculturalists can be important and as shown theoretically, can influence the socially optimal selection of aquaculture species and systems. Similarly, aquaculture can have environmental consequences for the rest of the community. The social economic implications of this for the selection of aquaculture species and systems are analyzed. Some paradoxical results are obtained. For example, if the quality of social governance of aquaculture is poor, aquaculture species and systems that cause a slow rate of environmental deterioration may be socially less satisfactory than those that cause a rapid rate of such deterioration. Socially optimal choice of aquaculture species and systems depends not only on their biophysical characteristics and market conditions but also on the prevailing state of governance of aquaculture. Failure to consider the last aspect can result in the introduction of new aquaculture species (and systems) doing more social harm than good.

description: The possibility of radiative effects induced by the Lorentz and CPT non-invariant interaction term for fermions in the Standard Model Extension is investigated. In particular, electron-positron photo-production and photon emission by electrons and positrons are studied. The rates of these processes are calculated in the Furry picture. It is demonstrated that the rates obtained in the framework of the model adopted strongly depend on the polarization states of the particles involved. As a result, ultra-relativistic particles produced should occupy states with a preferred spin orientation, i.e., photons have the sign of polarization opposite to the sign of the effective potential, while charged particle are preferably in the state with the helicity coinciding with the sign of the effective potential. This leads to evident spatial asymmetries which may have certain consequences observable at high energy accelerators, and in astrophysical and cosmological studies.

description: We study non-perturbatively the anomalous Hall current and its high harmonics generated in Weyl and Dirac semimetals by strong elliptically polarized laser fields, in the context of kinetic theory. We find a novel crossover between perturbative and non-perturbative regimes characterized by the electric field strength $\mathcal{E}^{*}= \frac{μω}{ 2 e v_F}$ ($ω$: laser frequency, $μ$: Fermi energy, $v_F$: Fermi velocity). In the perturbative regime, the anomalous Hall current quadratically depends on the field strength ($\mathcal{E}$), whereas the higher order corrections, as well as high harmonics, vanish at zero temperature. In the non-perturbative regime, the anomalous Hall current saturates and decays as $(\log{\mathcal{E}})/\mathcal{E}$, while even-order high harmonics are generated when inplane rotational symmetry is broken. Based on the analytical solution of the Boltzmann equation, we reveal the topological origin of the sharp crossover: the Weyl monopole stays inside or moves outside of the Fermi sphere, respectively, during its fictitious motion in the pertubative or non-pertubative regimes. Our findings establish a new non-linear response intrinsically connected to topology, characteristic to Weyl and Dirac semimetals.

description: Two-dimensional (2D) materials, such as transition metal dichalcogenides (TMDCs) in the 2H or 1T crystal phases, are promising (electro)catalyst candidates due to their high surface to volume ratio and composition of low-cost, abundant elements. While the edges of elemental TMDC nanoparticles, such as MoS$_2$, can show significant catalytic activity, the basal plane of the pristine materials are notoriously inert, which limits their normalized activity. Here we show that high densities of catalytically active sites can be formed on the TMDC basal plane by alloying elements that prefer the 2H (1T) phase into a 1T (2H) structure. The global stability of the alloy, in particular whether it crystallizes in the 2H or 1T phase, can be controlled by ensuring a majority of elements preferring the target phase. We further show that the mixing entropy plays a decisive role for stabilizing the alloy implying that high-entropy alloying becomes essential. Our calculations point to a number of interesting non-precious hydrogen evolution catalysts, including (CrHfTaVZr)S$_2$ and (CrNbTiVZr)S$_2$ in the T-phase and (MoNbTaVTi)S$_2$ in the H-phase. Our work opens new directions for designing catalytic sites via high-entropy alloy stabilization of locally unstable structures.

description: Reviews the literature to provide an overview of the historical significance of the elephant in Sri Lankan society, an association which dates back more than 4,000 years. The present status of this relationship assessed on the basis of the findings of a recent study undertaken on the total economic value of elephants in Sri Lanka. This paper, first briefly outlines the history, evolution, nature and their distribution of the Asian elephant while providing some insights on the status of the elephant (Elephas maxima maxima) in Sri Lanka. Next, it reviews the literature in order to assess the historical affiliation that the elephant has maintained with the Sri Lankan society, its culture, history, mythology and religion. The empirical evidence on the economic value of conservation of the remaining elephant population in Sri Lanka is reviewed and the Sri Lankan people’s attitudes towards conserving this species of wildlife. Literature reviewed and analysis undertaken indicates that the elephant in Sri Lanka, still, as in the past has a special place in Sri Lankan society, particularly, in its culture, religion and value system. Thus, there is a strong case for ensuring the survival of wild elephant population in Sri Lanka. Furthermore, it also suggests that the community as a whole will experience a net benefit from ensuring the survival of wild elephants in Sri Lanka.
Dynamic kink instability and transverse motions of solar spicules

Publisher: name: arXiv
Year: 2020
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Hydrodynamic jets are unstable to the kink instability (m=1 mode in cylindrical geometry) owing to the centripetal force, which increases the transverse displacement of the jet. When the jet moves along a magnetic field, then the Lorentz force tries to decrease the displacement and stabilises the instability of sub-Alfvenic flows. The threshold of the instability depends on the Alfven Mach number (the ratio of Alfven and jet speeds). We suggest that the dynamic kink instability may be of importance to explain observed transverse motions of type II spicules in the solar atmosphere. We show that the instability may start for spicules which rise up at the peripheries of vertically expanding magnetic flux tubes owing to the decrease of the Alfven speed in both, the vertical and the radial directions. Therefore, inclined spicules may be more unstable and have more higher transverse speeds. Periods and growth times of unstable modes in the conditions of type II spicules have the values of 30 s and 25-100 s, respectively, which are comparable to the life time of the structures. This may indicate to the interconnection between high speed flow and rapid disappearance of type II spicules in chromospheric spectral lines.

description: We study the low energy behavior of QCD Green functions in the limit that the baryon chemical potential is much larger than the QCD scale parameter $Λ_QCD$. We show that there is a systematic low energy expansion in powers of $(ω/m)^{1/3}$, where $ω$ is the energy and $m$ is the screening scale. This expansion is valid even if the effective quark-gluon coupling $g$ is not small. The expansion is purely perturbative in the magnetic regime $|\vec{k}| \gg k_0$. If the external momenta and energies satisfy $k_0 \sim |\vec{k}|$, planar, abelian ladder diagrams involving the full quark propagator have to be resummed but the corresponding Dyson-Schwinger equations are closed.

description: Motivated by the growing interest in band structures featuring higher-order Van Hove singularities (HOVHS), we investigate a spinless fermion kagome system characterized by nearest-neighbor (NN) and next-nearest-neighbor (NNN) hopping amplitudes. While NN hopping preserves time-reversal symmetry, NNN hopping, akin to chiral hopping on the Haldane lattice, breaks time-reversal symmetry and leads to the formation of topological bands with Chern numbers ranging from $C = \pm 1$ to $ \pm 4$. We perform analytical and numerical analysis of the energy bands near the high-symmetry points $\boldsymbolΓ$, $\pm \boldsymbol{K}$, and $\boldsymbol{M_i}$ ($i=1,2,$ and $3$), which uncover a rich and complex landscape of HOVHS, controlled by the magnitude and phase of the NNN hopping. We observe power-law divergences in the density of states (DOS), $ρ(ε) \sim |ε|^{-ν}$, with exponents $ν= 1/2, 1/3, 1/4$, which can significantly affect the anomalous Hall response at low temperatures when the Fermi level crosses the HOVHS. Additionally, the NNN hopping induces the formation of higher Chern number bands $C = \pm 2, \pm 4$ in the middle of the spectrum obeying a sublattice interference whereupon electronic states are maximally localized in each of the sublattices when the momentum approaches the three high-symmetry points $\boldsymbol{M_i}$ ($i=1,2,$ and $3$) on the Brillouin zone boundary. This classification of HOVHS in kagome systems provides a platform to explore unconventional electronic orders induced by electronic correlations.

description: We study the charge transport statistics in coherent two-terminal double junctions within the framework of the circuit theory of mesoscopic transport. We obtain the general solution of the circuit-theory matrix equations for the Green's function of a chaotic cavity between arbitrary contacts. As an example we discuss the full counting statistics and the first three cumulants for an open asymmetric cavity between a superconductor and a normal-metal lead at temperatures and voltages below the superconducting gap. The third cumulant shows a characteristic sign change as a function of the asymmetry of the two quantum point contacts, which is related to the properties of the Andreev reflection eigenvalue distribution.

description: The theory of contracts assumes that human nature is essentially opportunistic, and economic agents protect themselves against adverse selection and moral hazard by elaborating contracts. In the case of irrigated areas in the Brazilian northeast, such contracts are not necessarily formal. That is, arrangements based on economic agent’s word are common. The data used are from acerola producers in the Petrolina-Juazeiro irrigation project. The empirical model was tobit, given that the dependent variable was characterized by a truncated distribution. The results showed that the decision to engage on contractual relations is fundamentally defined by the degree of dependence of the farmer in respect to the processing industry. Furthermore, past experience of contractual relationship with the processing industry is a strong determinant of the individual’s behavior.

description: We perform numerical simulations of a long-range spherical spin glass with two and three body interaction terms. We study the gradient descent dynamics and the inherent structures found after a quench from initial conditions, well thermalized at temperature $T_{in}$. In large systems, the dynamics strictly agrees with the integration of the mean-field dynamical equations. In particular, we confirm the existence of an onset initial temperature, within the liquid phase, below which the energy of the inherent structures undoubtedly depends on $T_{in}$. This behavior is in contrast with that of pure models, where there is a 'threshold energy' that attracts all the initial configurations in the liquid. Our results strengthen the analogy between mean-field spin glass models and supercooled liquids.

description: A recent study has revealed that the low carrier density electron gas (2DEG) induced at the interface of EuO and (111) KTaO$_3$ exhibits a broken symmetry phase with a strong in-plane anisotropy of the resistivity. We present a minimal tight binding model of this (111) 2DEG, including the large spin-orbit coupling from the Ta ions, which reveals a hexagonal Fermi surface with a highly enhanced 2$k_F$ electronic susceptibility. We argue that repulsive electronic interactions, together with a ferromagnetic EuO substrate, favor a magnetic stripe instability leading to a partially gapped Fermi surface. Such a stripe state, or its vestigial nematicity, could explain the observed transport anisotropy. We propose a $k\cdot p$ theory for the low energy $j=3/2$ states, which captures the key results from our tight-binding study, and further reveals the intertwined dipolar and octupolar modulations underlying this magnetic stripe order. We conclude by speculating on the relation of this stripe order to the superconductivity seen in this material.

description: The objective of this paper was to compare and to analyze three portfolio selection models: Mean-Variance, Minimax and Minimax Weighted. These models were evaluated using historical data (September 1999 to August 2000, January 2001 to December 2001 and February 2002 to January 2003) obtained from the Brazilian Stock Market (Bovespa). They were selected optimal portfolios to each month based on the returns of the last twelve months. The results show that the returns obtained through the Mean-Variance model were superiors in certain circumstances and inferiors in others when compared to the Ibovespa index. The Minimax model obtained the best accumulated returns when compared with the others models and the Ibovespa index.

description: We study supersymmetric $AdS_6$ black holes from matter-coupled $F(4)$ gauged supergravity coupled to four vector multiplets with $ISO(3)\times U(1)$ gauge group. This gauged supergravity admits a maximally supersymmetric $AdS_6$ vacuum with $SO(3)\subset ISO(3)$ symmetry. We find a number of new supersymmetric $AdS_2\times \mathcal{M}_4$ solutions by performing topological twists along $\mathcal{M}_4$. For $\mathcal{M}_4$ being a product of two Riemann surfaces $Σ\times \widetildeΣ$, we perform a twist by $SO(2)\times U(1)$ gauge fields and find $AdS_2\times Σ\times \widetildeΣ$ solutions for at least one of the Riemann surface being negatively curved. For $\mathcal{M}_4$ being a Kahler four-cycle $\mathcal{M}_{\textrm{K}4}$, a twist by $SO(2)\times U(1)$ gauge fields leads to $AdS_2\times \mathcal{M}_{\textrm{K}4}^-$ solutions for negatively curved $\mathcal{M}_{\textrm{K}4}$. Finally, performing a twist by turning on $SO(3)$ gauge fields in the case of $\mathcal{M}_4$ being a Cayley four-cycle $\mathcal{M}_{\textrm{C}4}$ also leads to $AdS_2\times \mathcal{M}_{\textrm{C}4}^-$ solutions for negatively curved $\mathcal{M}_{\textrm{C}4}$. We give numerical black hole solutions interpolating between all of these $AdS_2\times \mathcal{M}_4$ near horizon geometries and the asymptotically locally $AdS_6$ vacuum. It is also possible to uplift all of these solutions to type IIB theory via consistent truncations on $S^2\times Σ$ leading to a new class of supersymmetric $AdS_2\times \mathcal{M}_4\times S^2\times Σ$ solutions.

For the cooperative or any other company to survive in the context of tough competition, one of the core issues to be concerned is quality. In order to accompany the present changes, the vision of cooperatives has been facing important modifications. An example of is this is Coopavel (Brazilian cooperative situated in the southern State of Paraná), which has launched a differentiated system of raw milk payment to assure the quality of its received milk, and, consequently, the improvement of its products’ quality. This paper proposes to present a case about Coopavel, analyzing its quality improvement program of milk production.

description: We present the design, manufacturing, and testing of a 37-element array of corrugated feedhorns for Cosmic Microwave Background (CMB) measurements between $140$ and $170$ GHz. The array was designed to be coupled to Kinetic Inductance Detector arrays, either directly (for total power measurements) or through an orthomode transducer (for polarization measurements). We manufactured the array in platelets by chemically etching aluminum plates of $0.3$ mm and $0.4$ mm thickness. The process is fast, low-cost, scalable, and yields high-performance antennas compared to other techniques in the same frequency range. Room temperature electromagnetic measurements show excellent repeatability with an average cross polarization level about $-20$ dB, return loss about $-25$ dB, first sidelobes below $-25$ dB and far sidelobes below $-35$ dB. Our results qualify this process as a valid candidate for state-of-the-art CMB experiments, where large detector arrays with high sensitivity and polarization purity are of paramount importance in the quest for the discovery of CMB polarization $B$-modes.

description: Considering a quantized chaotic system, we analyze the evolution of its eigenstates as a result of varying a control parameter. As the induced perturbation becomes larger, there is a crossover from a perturbative to a non-perturbative regime, which is reflected in the structural changes of the local density of states. For the first time the {\em full} scenario is explored for a physical system: an Aharonov-Bohm cylindrical billiard. As we vary the magnetic flux, we discover an intermediate twilight regime where perturbative and semiclassical features co-exist. This is in contrast with the {\em simple} crossover from a Lorentzian to a semicircle line-shape which is found in random-matrix models.

description: The production of desserts and fruit jellies is a traditional agribusiness activity in the south of Brazil, especially in Pelotas, Rio Grande do Sul. However, the Brazilian commercial opening that was processed in the beginning of the 1990’ years, it influenced negatively this segment, mainly in relation to the peach. This resulted in a new roll of conditions that culminated in the need of a revaluation of the transactional behavior among the agents involved in this segment. In this aspect, it is necessary to consider that the agribusiness system capacity of organization depends on the contractual arrangements that are established among them. In spite of these contractual relationships that causes an influence on the system efficiency it depends, not only of the assets involved characteristics and the agents’ behavior, but the institutional, organizational and technological aspects also influence it. About it, this paper intent to identify the presence of transaction costs in the contractual relationships established in the peach agribusiness system in Pelotas. In this sense, the analysis locates inside of the New Institutional Economy approach and in the Transaction Costs Economic theory.

description: Este trabalho estima uma equação de demanda de exportações brasileiras de café, considerando-se o período de 1980 a 2001, por parte dos países importadores. As principais variáveis determinantes dessa demanda são o preço do café brasileiro, o preço do café colombiano e a quantidade mundial exportada de café. Essa última variável é considerada proxy da renda dos consumidores estrangeiros e dos gostos desses consumidores de café brasileiro. Constatou-se que a demanda de exportações brasileiras de café apresenta elasticidade-preço e preço-cruzada próxima da unidade, e elasticidaderenda inferior a um. Esse alto valor absoluto da elasticidade-preço da demanda internacional de café brasileiro, provavelmente, é fruto do cenário internacional que caracterizou o mercado de café no período analisado por este trabalho.

description: We use the observed polarisation properties of a sample of 26 powerful radio galaxies and radio-loud quasars to constrain the conditions in the Faraday screens local to the sources. We adopt the cosmological redshift, low-frequency radio luminosity and physical size of the large-scale radio structures as our `fundamental' parameters. We find no correlation of the radio spectral index with any of the fundamental parameters. The observed rotation measure is also independent of these parameters. The difference between the rotation measures of the two lobes of an individual source as well as the dispersion of the rotation measure show significant correlations with the source redshift, but not with the radio luminosity or source size. Thus the small-scale structure observed in the rotation measure is caused by a Faraday screen local to the sources. The observed asymmetries between the lobes of our sources show no significant trends with each other or other source properties. Finally, we show that the commonly used model for the depolarisation of synchrotron radio emission by foreground Faraday screens is inconsistent with our observations. We apply alternative models to our data and show that they require a strong increase of the dispersion of the rotation measure inside the Faraday screens with cosmological redshift. Correcting our observations with these models for redshift effects, we find a strong correlation of the depolarisation measure with redshift and a significantly weaker correlation with radio luminosity. All our results are consistent with a decrease in the order of the magnetic field structure of the Faraday screen local to the sources for increasing cosmological redshift. (abridged)

Locating the chromatin modifying factor Suppressor of Variegation 3-8 in Drosophila melanogaster

description: This study is part of a project whose goal is to identify and then sequence the chromatin modifying gene Su(var)3-8. Chromatin structure is considered to play a significant role in gene expression. In order to better understand this role, we have undertaken a project to characterize one gene suspected of affecting chromatin structure, Su(var)3-8. The first approach taken was to tag the gene with a known sequence - the P element transposon. Mutations of Su(var)3-8 created by P element mutagenesis were tested to determine whether P elements were inserted in the gene. Remobilization of the P element by a cross that introduced transposase was used to detect reverted suppressors, under the supposition that precise excision of a mutation-causing P element would revert the gene to wild-type state. Southern blotting using radioactively labelled complete P element to probe digested genomic DNA was used to detect partial (immobile) remnants of P elements. Recessive lethal mutations containing P elements inserted in the region near Su(var)3-8 were tested for complementation to determine whether those P elements were inserted into the 3-8 locus. As no P-tagged alleles were discovered, Su(var)3-8 was then localized with the intention of delimiting the potential area to a few genes, allowing for direct testing of putative genes via plasmid rescue. Su(var)3-8 was localized genetically using recombination mapping with the genes cross-veinless and stubbloid, situated on the chromosomal arm 3R and near where previous studies placed Su(var)3-8 (53.5±0.9 ). 3-8 was localized cytologically by complementation to various recessive lethal chromosomal deficiencies also determined to be in the vicinity. It was not possible to localize the area sufficiently to allow for direct testing of open reading frames. 128 putative genes are located in the 1645Kb within which Su(var)3-8 appears to be located.

description: O objetivo deste estudo foi identificar os atributos valorizados na contratação de operações logísticas pelos embarcadores na tomada de decisões no mercado de commodities agrícolas, com interesse específico na identificação dos principais critérios para contratação e avaliação de um operador logístico. A utilização de operadores logísticos pode ser entendida a partir do aperto nas margens de operação, que tem forçado as empresas a tomarem decisões sobre a viabilidade de otimizarem todas as operações ou buscarem em prestadores de serviço a solução otimizadora. As informações foram obtidas de questionários encaminhados aos responsáveis pela comercialização de empresas que comercializam um volume significativo de grãos. Como síntese dos resultados, pôde-se constatar que o transporte é a principal e, às vezes, única dentro da visão logística do setor. Mesmo que não-sistemática, avaliação da qualidade do serviço prestado é feita pelo embarcador. A freqüência das operações faz com que seja facilitada a tarefa de avaliação do desempenho dos prestadores de serviço. Conforme avaliação dos embarcadores, os itens mais importantes no serviço prestado são, na seqüência, flexibilidade, reação às reclamações e o serviço de transporte propriamente dito. Em suma, pode-se concluir que existe rigidez na gestão logística da comercialização de commodities agrícolas, e os embarcadores, estrategicamente ou pela própria dinâmica do mercado, tendem a “commoditizar” os serviços logísticos, não avaliando o potencial de ganho de terceirização de operações além do transporte, o que faz com que, para esses negócios, transporte e logística sejam sinônimos.

description: Using truth-level Monte Carlo simulations of particle interactions in a large volume of liquid argon, we demonstrate physics capabilities enabled by reconstruction of topologically compact and isolated low-energy features, or `blips,' in large liquid argon time projection chamber (LArTPC) events. These features are mostly produced by electron products of photon interactions depositing ionization energy. The blip identification capability of the LArTPC is enabled by its unique combination of size, position resolution precision, and low energy thresholds. We show that consideration of reconstructed blips in LArTPC physics analyses can result in substantial improvements in calorimetry for neutrino and new physics interactions and for final-state particles ranging in energy from the MeV to the GeV scale. Blip activity analysis is also shown to enable discrimination between interaction channels and final-state particle types. In addition to demonstrating these gains in calorimetry and discrimination, some limitations of blip reconstruction capabilities and physics outcomes are also discussed.

description: Inspired by a recently proposed superconducting mechanism for a new cuprate superconductor Ba$_2$CuO$_{3+δ}$, we theoretically design an unconventional nickelate superconductor with $d^8$ electron configuration. Our strategy is to enlarge the on-site energy difference between $3d_{x^2-y^2}$ and other $3d$ orbitals by adopting halogens or hydrogen as out-of-plane anions, so that the $3d$ bands other than $d_{x^-y^2}$ lie just below the Fermi level for the $d^8$ configuration, acting as incipient bands that enhance superconductivity. We also discuss a possible relevance of the present proposal to the recently discovered superconductor (Nd,Sr)NiO$_2$.

description: A sample of white dwarfs is selected from SDSS DR3 imaging data using their reduced proper motions, based on improved proper motions from SDSS plus USNO-B combined data. Numerous SDSS and followup spectra (Kilic et al. 2005) are used to quantify completeness and contamination of the sample; kinematic models are used to understand and correct for velocity-dependent selection biases. A luminosity function is constructed covering the range 7 < M_bol < 16, and its sensitivity to various assumptions and selection limits is discussed. The white dwarf luminosity function based on 6000 stars is remarkably smooth, and rises nearly monotonically to M_bol = 15.3. It then drops abruptly, although the small number of low-luminosity stars in the sample and their unknown atmospheric composition prevent quantitative conclusions about this decline. Stars are identified that may have high tangential velocities, and a preliminary luminosity function is constructed for them.

description: Este artigo tem o principal objetivo de identificar o comportamento dos gastos públicos em agricultura no estado de Minas Gerais, no período de 1985 a 2001. Constatou-se tendência à diminuição do volume desses gastos e à pulverização institucional destes, o que indica progressivo esvaziamento de tradicionais atribuições do Estado de apoio e fomento ao setor agrícola, acompanhado de crescente superposição de competências para gastar a verba pública alocada na função agricultura e de sua conseqüente diluição entre distintos sistemas operacionais da administração pública. Se o padrão de distribuição do gasto público em agricultura em Minas Gerais representa bem o que ocorre no resto do país, pode-se concluir que, no que concerne à intervenção do Estado na economia do setor agropecuário, o Brasil está na contramão das tendências atuais dos países mais desenvolvidos, nos quais, cada vez mais, esse setor é enfocado num contexto holístico, envolvendo, de forma integrada, múltiplos objetivos e políticas de preservação do meio ambiente e das culturas autóctones, a segurança alimentar, a inclusão social e a ocupação do espaço nacional.
