description: This study is conducted due to the importance of GDP mea-suring in relation to policy making and because of the market globali-zation that forced agribusiness, and all other sectors of the economy, to optimize their productive units to become more competitive. This study derives the concept and sector characterization of what represents the Agribusiness Complex. It also brings up all methodology used in me-asuring Pernambuco Agribusiness Complex. In the analysis, the sector classification of Pernambuco Agribusiness Complex and the measuring of the GDP of the Agribusiness Complex, where sectors belonging to hi-gher and lower levels of production chains, including the nucleus, and taxes are presented. Among other results related to the participation of higher and lower sectors of production chains, as well as the nucleus, it’s pointed out that the agribusiness GDP in Pernambuco represents 21.2% of the total state GDP, against 7.7% pointed out by official statistics for the primary sector.....Este estudo é realizado devido à importância do cálculo do PIB (Produto Interno Bruto) para a formulação e direcionamento de políticas, e, também, por conta da abertura dos mercados, que forçou o agronegócio, e todos os demais setores da economia, a otimizarem as suas unidades produtivas a fim de se tornarem mais competitivas. O presente trabalho conceitua e faz a caracterização setorial do que venha a ser o complexo agroindustrial (CAI), ou, em outras palavras, o agronegócio. Também trás à tona toda a metodologia usada no dimensionamento do CAI pernambucano. Na análise, a classificação setorial do CAI pernambucano e a mensuração do PIB do CAI são apresentadas. Nestas participam as mensurações dos setores que ficam a montante e a jusante, do núcleo (produto agropecuário) e dos impostos. Além de outros resultados relacionados à participação dos setores a montante, a jusante e sobre o núcleo do agronegócio, aponta-se que o PIB do agronegócio de Pernambuco representa 21,2% do PIB total do estado, contra 7,7% apontados por estatísticas oficiais para o setor primário.

description: A generalized Weyl integrable geometry (GWIG) is obtained from simultaneous affine transformations of the tangent and cotangent bundles of a (pseudo)-Riemannian manifold. In comparison with the classical Weyl integrable geometry (CWIG), there are two generalizations here: interactions with an arbitrary dark field, and, anisotropic dilation. It means that CWIG already has interactions with a {\it null} dark field. Some classical mathematics and physics problems may be addressed in GWIG. For example, by derivation of Maxwell's equations and its sub-sets, the conservation, hyperbolic, and elliptic equations on GWIG; we imposed interactions with arbitrary dark fields. Moreover, by using a notion analogous to Penrose conformal infinity, one can impose boundary conditions canonically on these equations. As a prime example, we did it for the elliptic equation, where we obtained a singularity-free potential theory. Then we used this potential theory in the construction of a non-singular model for a point charged particle. It solves the difficulty of infinite energy of the classical vacuum state.

description: We describe a method that allows for a practical application of the theory of pseudo-Hermitian operators to PT-symmetric systems defined on a complex contour. We apply this method to study the Hamiltonians $H=p^2+x^2(ix)^ν$ with $ν\in(-2,\infty)$ that are defined along the corresponding anti-Stokes lines. In particular, we reveal the intrinsic non-Hermiticity of $H$ for the cases that $ν$ is an even integer, so that $H=p^2\pm x^{2+ν}$, and give a proof of the discreteness of the spectrum of $H$ for all $ν\in(-2,\infty)$. Furthermore, we study the consequences of defining a square-well Hamiltonian on a wedge-shaped complex contour. This yields a PT-symmetric system with a finite number of real eigenvalues. We present a comprehensive analysis of this system within the framework of pseudo-Hermitian quantum mechanics. We also outline a direct pseudo-Hermitian treatment of PT-symmetric systems defined on a complex contour which clarifies the underlying mathematical structure of the formulation of PT-symmetric quantum mechanics based on the charge-conjugation operator. Our results provide a conclusive evidence that pseudo-Hermitian quantum mechanics provides a complete description of general PT-symmetric systems regardless of whether they are defined along the real line or a complex contour.

description: Study demonstrates occurrence of unilateral type neurodegeneration in hippocampal sub region (CA2 and CA4) of female rats that given four hours swimming stress and unique rotational behavior. Stressed rats’ brain sections, stained with cresyl violet, passing through bregma -1.8 to -3.8 levels, demonstrated degenerative changes in the cell bodies of CA2 and CA4 hippocampal sub regions of right hemisphere. These changes were observed in 50% of rats. Reason lying behind the unilateral degeneration after exposure to swimming stress could not be explained. To our knowledge, it is the first report demonstrating unilateral hippocampal degeneration.

description: The heating and cooling of the interstellar medium allow the gas in the ISM to coexist at very different temperatures in thermal pressure equilibrium. The heating cannot be directly determined, but the cooling can be inferred from observations of C II*, which is an important coolant in different environments. The amount of cooling can be measured through either the intensity of the 157.7 \micron [C II] emission line or the C II* absorption lines at 1037.018 Å and 1335.708 Å, observable with FUSE and HST/STIS, respectively. We present the results of a survey of these far-UV absorption lines in 43 objects situated at |b|>30. We derive the cooling rates and analyze the ionization structure, the depletion, and metallicity content from the column densities of C II*, S II, P II, Fe II, and H I 21-cm emission for the low-, intermediate-, and high-velocity clouds (LVCs, IVCs, and HVCs) along the different sightlines. Based on the depletion and the ionization structure, the LVCs, IVCs, and HVCs consist mostly of warm neutral and ionized clouds. For the LVCs, the mean cooling rate in erg\,s^{-1} per H atom is -25.70^{+0.19}_{-0.36} dex. The corresponding total Galactic C II luminosity in the 157.7 \micron emission line is L~2.6x10^7 L_\sun. Combining N(C II*) with the intensity of H$α$ emission, we derive that ~50% of the C II* radiative cooling comes from the warm ionized medium (WIM). The large dispersion in the cooling rates is certainly due to a combination of differences in the ionization fraction, in the dust-to-gas fraction, and physical conditions between sightlines. For the IVC IV Arch at z~1 kpc we find that on average the cooling is a factor 2 lower than in the LVCs that probe gas at lower z. For an HVC (Complex C, at z > 6 kpc) we find the much lower rate of -26.99^{+0.21}_{-0.53} dex. [Abridged]

title: Mind-Body Bridging (MBB) Techniques and Emotional Regulation in Political Discourse and Confidence in Political Talk

description: In today's politically divided landscape, conversations across political lines can often provoke intense feelings of anger and anxiety, making productive dialogue difficult. This polarization not only dampens the quality of public discourse but also affects individual emotional well-being and the broader societal cohesion. This study explores a novel approach to alleviating the negative emotional effects caused by political polarization, using Mind-Body Bridging (MBB) techniques. It specifically targets emotional regulation- how we control and manage our feelings- during political discussions, without attempting to change participants' political beliefs. The study involved participants from Utah State University setting who engaged in MBB training. These participants were then observed for before and after changes in their emotional regulation and confidence during political conversations. The results suggest that while MBB practices helped some individuals manage their emotional responses more effectively, the overall impact on increasing confidence in political discussions was not definitive. The study suggests that more extensive application and a larger participant pool could provide clearer insights into the effectiveness of MBB in political contexts. The study highlights an innovative approach to one of the most pressing matters in contemporary politics- how to maintain healthy, productive political discussions in an era of high emotional stakes and polarization.

description: This work was carried out with the objective of both evalua-ting costs and identifying the shut-down point in milk production in Mi-nas Gerais State. According to theories on both production and costs, the shut-down point is defined as the lowest price dairy farmers could afford supplying milk to market and still be able to cover their variable expen-ses. Data involving 574 commercial dairy farmers from all mesoregions in the state were analysed during the agricultural years 1995/6 – 2001/2. The economical profile analysis of the sector show that the cost of the product per unit was high. Economical results show both scale gain and an existing production level where the average variable cost is minimi-zed. Therefore the shut-down point of milk production in Minas Gerais was estimated to be R$ 0,42. At this estimated price 1.299,45 liters of milk per day can be supplied. In the case of lower prices production will not be able to continue.....Através deste estudo, buscou-se avaliar os custos e identificar o shut-down point da atividade leiteira no Estado de Minas Gerais. Conforme as teorias da produção e do custo, o shut-down point representa o menor preço do produto em que a empresa poderia continuar produzindo, sendo suficiente apenas para cobrir os custos variáveis. Para preços situados abaixo desse ponto, não haveria oferta de leite pela empresa. Analisaram-se informações referentes a 574 produtores comerciais de leite provenientes de todas as mesorregiões do estado, tendo o período de estudo compreendido os anos agrícolas de 1995/96 a 2001/02. A análise do perfil econômico do setor demonstrou que os produtores pesquisados incorreram em altos custos por unidade produzida, sugerindo baixa eficiência técnica da atividade leiteira e falhas na administração do empreendimento. Os resultados econométricos evidenciaram a ocorrência de ganhos de escala e o shut-down point da atividade leiteira em Minas Gerais foi estimado em R$ 0,42. Este valor representa o limite da resistência do pecuarista quanto ao declínio dos preços recebidos, ao qual o produtor estaria disposto a ofertar 1.299,45 litros de leite por dia, interrompendo a produção para preços menores.

description: The object of study in this research is the ecotourism experience developed in the Poço Encantado Waterfall located in Teresina de Goiás, in the Chapada dos Veadeiros region, Northeast of Goiás. It is a family business established since 1996 opened to public visitation which offers rural and ecological tourism. The activities developed there are also re-lated to the territory of the biggest remaining community of quilombos in Brazil: the Kalunga community. In order to understand this object of study we attempted to attain the following objectives: a) To know the strategies that form and were implemented in the chain of ecotourism in the waterfall of Poço Encantado; b) To understand in what ways the Kalunga people are inserted within such chain; c) To reflect about the formulation and implementation of public policies which can benefit the Quilombolas communities in Brazil; d) To provide a plan concerning future perspectives. In this research, we chose the single case study as a methodological resource. We consider the Poço Encantado Waterfall to be a unique ma-nifestation that must be contextualized and part of the present capitalist society which presents itself in a contradictory and dynamic way. The purpose of this research is to contribute in the agribusiness field. This business proposition is to analyze and point out immediate and viable ways to change the approach and strategies in the activities involved along the productive chains.
Fishing impacts on marine ecosystems off Brazil : with emphasis on the northeastern region

Publisher: name: University of British Columbia
Year: 2009

description: This study is the first contribution towards the development of ecosystem-based fisheries management in northeastern Brazil, through the exploration of fishing policies based on a trophic model. The following objectives were addressed: 1) analysis of the richness of common names of Brazilian fishes; 2) reconstruction of time series of marine catches; 3) modelling of trophic interactions off northeastern Brazil; and 4) assessment of fishing policies. The analysis of common names indicated a high richness of names per species (average = 6) and the use of the same common name for different species, with a negative impact on the accuracy of catch statistics. The reconstruction of catch time series was based on landings from national yearbooks, and from ICC AT and FAO's databases (1978-2000), allowing for the detection of 'fishing down the food web' in northeastern Brazil. The trophic model estimated a total biomass for this ecosystem of 222 tonnes km⁻² (excluding detritus), and indicated a low degree of omnivory and the high importance of detritus. Simulations for 2001-2028 indicated that current fishing effort is unsustainable for lobsters and swordfish; however, the model inadequately described the dynamics of swordfish, tunas, and other large pelagics, which have large distribution areas. The simulation of optimum fishing policies led to a diverse fleet when ecosystem health was emphasized. If the main objective was economic or social (or a combination of both and ecosystem health), manual collection of coastal resources, and demersal industrial fisheries could be boosted, while the lobster and longline fisheries should be phased out. A 50% reduction in effort for lobster fisheries would not produce significant changes in lobster biomass; a reduction in effort to the 1978 level (f[sub MSY]) would lead to biomass recovery. The instability of institutions responsible for fisheries management in Brazil has had a deleterious impact on the resources. This negative impact is expected to increase due to the current split of responsibility between two institutions with diverse agendas. An improvement in the collection system of catch statistics is recommended, which would consider a standardized set of common names, as well as gathering information on biological, economic, and social components of this ecosystem and its fisheries.

description: The relationship between fluoride and its toxic effects has been studied for years by researchers. Studies suggest that small amounts of fluoride are beneficial in terms of prevention of dental caries and strengthen bones. Several reports are available on the long-term exposure of fluoride to low/high concentration and adverse effects on organisms. Although plenty of literature is available only a few interprets the results scholarly. The purpose of this article is to review the claims on fluorosis and examining the objectivity or biases of published articles. We present an unconventional interpretation of fluoride toxicity and fluorosis.

description: Convection and magnetic field generation in the Earth and planetary interiors are driven by both thermal and compositional gradients. In this work numerical simulations of finite-amplitude double-diffusive convection and dynamo action in rapidly rotating spherical shells full of incompressible two-component electrically-conducting fluid are reported. Four distinct regimes of rotating double-diffusive convection identified in a recent linear analysis (Silva et al., 2019, Geophys. Astrophys. Fluid Dyn., doi:10.1080/03091929.2019.1640875) are found to persist significantly beyond the onset of instability while their regime transitions remain abrupt. In the semi-convecting and the fingering regimes characteristic flow velocities are small compared to those in the thermally- and compositionally-dominated overturning regimes, while zonal flows remain weak in all regimes apart from the thermally-dominated one. Compositionally-dominated overturning convection exhibits significantly narrower azimuthal structures compared to all other regimes while differential rotation becomes the dominant flow component in the thermally-dominated case as driving is increased. Dynamo action occurs in all regimes apart from the regime of fingering convection. While dynamos persist in the semi-convective regime they are very much impaired by small flow intensities and very weak differential rotation in this regime which makes poloidal to toroidal field conversion problematic. The dynamos in the thermally-dominated regime include oscillating dipolar, quadrupolar and multipolar cases similar to the ones known from earlier parameter studies. Dynamos in the compositionally-dominated regime exhibit subdued temporal variation and remain predominantly dipolar due to weak zonal flow in this regime. These results significantly enhance our understanding of the primary drivers of planetary core flows and magnetic fields.

description: We study the effects of inter-electron interactions on the charge pumped through an adiabatic quantum electron pump. The pumping is through a system of barriers, whose heights are deformed adiabatically. (Weak) interaction effects are introduced through a renormalisation group flow of the scattering matrices and the pumped charge is shown to {\it always} approach a quantised value at low temperatures or long length scales. The maximum value of the pumped charge is set by the number of barriers and is given by $Q_{\rm max} = n_b -1$. The correlation between the transmission and the charge pumped is studied by seeing how much of the transmission is enclosed by the pumping contour. The (integer) value of the pumped charge at low temperatures is determined by the number of transmission maxima enclosed by the pumping contour. The dissipation at finite temperatures leading to the non-quantised values of the pumped charge scales as a power law with the temperature ($Q-Q_{\rm int} \propto T^{2α}$), or with the system size ($Q-Q_{\rm int} \propto L_s^{-2α}$), where $α$ is a measure of the interactions and vanishes at $T=0 ~(L_s=\infty)$. For a double barrier system, our result agrees with the quantisation of pumped charge seen in Luttinger liquids.

description: Standard two-parameter compressions of the infinite dimensional dark energy model space show crippling limitations even with current SN-Ia data. Firstly they cannot cope with rapid evolution - the best-fit to the latest SN-Ia data shows late and very rapid evolution to w_0 = -2.85. However all of the standard parametrisations (incorrectly) claim that this best-fit is ruled out at more than 2-sigma, primarily because they track it well only at very low redshifts, z < 0.2. Further they incorrectly rule out the observationally acceptable region w << -1 for z > 1. Secondly the parametrisations give wildly different estimates for the redshift of acceleration, which vary from z_{acc}=0.14 to z_{acc}=0.59. Although these failings are largely cured by including higher-order terms (3 or 4 parameters) this results in new degeneracies which open up large regions of previously ruled-out parameter space. Finally we test the parametrisations against a suite of theoretical quintessence models. The widely used linear expansion in z is generally the worst, with errors of up to 10% at z=1 and 20% at z > 2. All of this casts serious doubt on the usefulness of the standard two-parameter compressions in the coming era of high-precision dark energy cosmology and emphasises the need for decorrelated compressions with at least three parameters.

description: Das österreichische Programm zur Förderung einer umweltgerechten, extensiven und den natürlichen Lebensraum schützenden Landwirtschaft (ÖPUL) und das Investitionsförderprogramm sind neben der Ausgleichszulage für benachteiligte Gebiete (AZ) die wichtigsten Instrumente des Ländlichen Entwicklungsprogramms in Österreich. Im Sinne eines effizienten Einsatzes staatlicher Mittel sind mögliche auftretende Zielkongruenzen zwischen diesen Förderinstrumenten von besonderem Interesse. Dies gilt insbesondere hinsichtlich der Umstellung auf biologische Wirtschaftsweise und der Inanspruchnahme von Investitionsförderung. So ergeben sich bei einer Umstellung auf biologische Wirtschaftsweise vor allem im Bereich der Tierhaltung zusätzliche Anforderungen, die vielfach entsprechende Investitionen erforderlich machen. Für solche Investitionen in Stallsysteme und andere bauliche Anlagen können Landwirte das Investitionsförderprogramm (Maßnahme M121 des Österreichischen Programms zu ländlichen Entwicklung) in Anspruch nehmen. In dieser Arbeit wird mit Hilfe statistischer Methoden der Zusammenhang zwischen der Inanspruchnahme der Investitionsförderung und der Teilnahme an ÖPUL-Maßnahmen ermittelt. Darüber hinaus wird mit Hilfe des Differenz-in-Differenz Schätzers die Wirkung der Wechselwirkungen der Fördermaßnahmen „Investitionsförderung“ und „Umstellung auf die biologische Wirtschaftsweise“ für den wirtschaftlichen Erfolg landwirtschaftlicher Unternehmen quantifiziert. Als Indikator für wirtschaftlichen Erfolg wird der Standarddeckungsbeitrag verwendet. Die Ergebnisse zeigen einen überwiegend positiven Zusammenhang zwischen Investitionsförderung und der Teilnahme an Maßnahmen des Agrarumweltprogramms ÖPUL, wobei es zwischen den einzelnen Betriebsformen erhebliche Unterschiede gibt. Die detaillierte Betrachtung der Wechselwirkungen zwischen Investitionsförderung und der ÖPUL-Maßnahme „biologische Wirtschaftsweise“ zeigt, mit Ausnahme von den Veredelungsbetrieben, signifikant höhere Teilnahmeraten bei gleichzeitiger Inanspruchnahme einer Investitionsförderung. Des Weiteren profitieren vor allem Futterbaubetriebe von der Umstellung auf biologische Landwirtschaft, während Dauerkultur- und Veredelungsbetriebe, unabhängig von einer Bioumstellung, positive Effekte vorwiegend durch die Investitionsförderung verzeichnen.

description: Large-scale structure calculations show that modest overdensity filaments will connect clusters of galaxies and these filaments are reservoirs of baryons, mainly in gaseous form. To determine whether such filaments exist, we have examined the UV absorption line properties of three AGNs projected behind possible filaments in superclusters of galaxies; the AGNs lie within 3 Mpc of the centerlines of loci connecting clusters. All three lines of sight show absorption in Lyα, Lyβ, or/and OVI at redshifts within about 1300 km/s of the nearby galaxy clusters that would define the closest filaments. For one AGN, the absorption line redshifts are close to the emission line redshift of the AGN, so we cannot rule out self-absorption for this object. These absorption line associations with superclusters are unlikely to have occurred by chance, a result consistent with the presence of cosmic filaments within superclusters.

description: Indices quantifying the performance of classifiers under class-imbalance, often suffer from distortions depending on the constitution of the test set or the class-specific classification accuracy, creating difficulties in assessing the merit of the classifier. We identify two fundamental conditions that a performance index must satisfy to be respectively resilient to altering number of testing instances from each class and the number of classes in the test set. In light of these conditions, under the effect of class imbalance, we theoretically analyze four indices commonly used for evaluating binary classifiers and five popular indices for multi-class classifiers. For indices violating any of the conditions, we also suggest remedial modification and normalization. We further investigate the capability of the indices to retain information about the classification performance over all the classes, even when the classifier exhibits extreme performance on some classes. Simulation studies are performed on high dimensional deep representations of subset of the ImageNet dataset using four state-of-the-art classifiers tailored for handling class imbalance. Finally, based on our theoretical findings and empirical evidence, we recommend the appropriate indices that should be used to evaluate the performance of classifiers in presence of class-imbalance.

description: L’objectif principal de ce travail est d’analyser l’impact du changement climatique sur la productivité des cultures céréalières dans la région de Béja, située au nord-ouest de la Tunisie. Pour ce faire, des modèles de régression multiple ont été estimés pour trois cultures céréalières (blé dur, blé tendre et orge). Les variables explicatives du rendement utilisées dans l’analyse sont celles d’ordre climatique (précipitations et températures) et le progrès technique. La période d’analyse est de 1980 à 2009. Les estimations des modèles de régression semi-logarithmiques ont montré que les rendements des différentes cultures céréalières dépendaient des variables climatiques et du progrès technique. L’analyse de la projection des effets du changement climatique sur les rendements céréaliers dans la zone d’étude, en utilisant les scénarios du modèle HadCM3, a montré que l’impact est important à l’horizon de 2030. Cet impact sera plus accentué pour le blé tendre. Ainsi, l’encouragement de la recherche en matière d’identification de nouvelles techniques agricoles, la diffusion de variétés tolérantes à la diminution des précipitations, dans les périodes critiques de croissance, et de variétés précoces, font partie des stratégies d’adaptation pour la réduction des effets du changement climatique sur le rendement céréalier à long terme......
description: This article analyzes the potential impact of climate change on cereal productivity in the Béja region of northwestern Tunisia. Multiple regression models were estimated for the cereal crops durum wheat, bread wheat and barley, using annual data from 1980 to 2009. The yield of each crop was used as the dependent variable, while the explanatory variables were mainly related to the climate (precipitation and temperature) and technological progress. The results show that yield variability is affected by climate and technological progress variables. The projected climate change scenarios predicted by the HadCM3 model will have a significant effect on crop yields by 2030, particularly for bread wheat. Some adaptation strategies that could alleviate climate change effects on cereal crops yields in the long run are the identification of new agricultural practices in this area, the widespread diffusion of varieties that can tolerate rainfall shortage during the critical periods, and the adoption of early maturing varieties.

description: An important parameter that affects PV panel performance of a solar power system is the incident solar radiation with the panel or panel's area of exposure to the sun. The direction and tilt angle of a PV panel are two important factors in PV system design. This paper itself presents the calculation of the optimum installation angles for the seasonal adjusting of solar cell panels considering apparent motion of the sun. Daily adjusting for optimal tilt angle can increase the received energy from the sun. However, making trade-off is required because changing the panel angle daily costs lots of endeavour, so we designed seasonal angles for installation of panels.

description: Reference arXiv:physics/0408021 claims that matter--free regions of spacetime may support electromagnetic waves for which the phase velocity 3-vector is oppositely directed to the power flow 3-vector. This was the definition of negative refraction adopted in \cite{ML}. We here show that this cannot occur in regions of spacetime for which the electromagnetic energy density is positive.

description: The longitudinal and Hall resistances have recently been measured for quantum Hall bilayers at total filling $ν=1$ in the superfluid state with interlayer pairing, both for currents flowing parallel to one another and for "counterflowing" currents in the two layers. Here I examine the contribution to these resistances from the motion of unpaired vortices in these systems, developing some possible explanations of various qualitative features of these data.

description: Recently, it was proposed to use measurements of Bd(t) -> D(*)+ D(*)- and Bd -> Ds(*)+ D(*)- decays to measure the CP phase gamma. In this paper, we present the extraction of gamma using this method. We find that gamma is favored to lie in one of the ranges [19.4o - 80.6o] (+ 0o or 180o), [120o - 147o] (+ 0o or 180o), or [160o - 174o] (+ 0o or 180o) at 68% confidence level (the (+ 0o or 180o) represents an additional ambiguity for each range). These constraints come principally from the vector-vector final states; the vector-pseudoscalar decays improve the results only slightly. Although, with present data, the constraints disappear for larger confidence levels, this study does demonstrate the feasibility of the method. Strong constraints on gamma can be obtained with more data.

(LMBC); Paratype: 1 male, the same data (LMBC). Differential diagnosis. Plateros kalamensis sp. n. is very characteristic by the shape of male genitalia (Figs 1, 2). It shares with P. milenae sp. n. eyes larger than interocular distance and differs from the later in parallel­sided antennomere 3 (Figs 21, 24). Description. Body small, slender, parallel­sided, black, covered with dense grey pubescence. Head small, eyes hemispherically prominent, eye diameter 1.13 times interocular distance. Antennae slender, reaching two thirds of elytral length, antennomeres almost parallel­sided, with long, erected pubescence (Fig. 21). Apical antennomeres slender, weakly flattened. Pronotum 1.5 times wider at base than long at midline, frontal margin widely rounded, frontal angles very obtuse, inconspicuous (Fig. 14). Posterior angles acutely projected. Pronotal disc mat, with deep depressions at frontal angles, with two short keels at middle of basal margin, covered with long light pubescence. Elytra parallelsided, with fine, inconspicuous costae, covered with dense light pubescence. Male genitalia very slender, widened in apical part, internal sac membranous, exposed (Figs 1, 2). Measurements. BL 5.50 mm, WH 1.22 mm PL 0.71 mm, PW 1.07 mm, Ediam 0.40 mm, Edist 0.36 mm. Distribution. Central Sulawesi Province, Mamasa valley. Etymology.

description: This guide is designed econometrics laboratory for economists users allowing them to know the tool to contribute to the socio-economic analysis to improve sector policies. It is a guide used in Econometrics components provided in the school for Business Economics Christian Autonomous University of Nicaragua, UCAN. The aim of this series of guides is that the user knows and applies the Eviews software tool and fundamentally that it develops skills for socio-economic analysis applied to the economy of primary, secondary and tertiary sectors. The manual is organized in 8 laboratories which correspond to the first part of the component of Econometrics Economics schools. These labs contain a theoretical supported from Mandala basic text, and a practical explanation Eviews software usage. It is important to note that over time the versions of this software vary so that in practice some commands also vary. However, the user depending on the version you will need to find or implement that change based on the basic explanation offered in this manual. We add an appendix that defines the interpretation of key test parameters Eviews and a calculation for interpolation. It is important to note that at present the applied science researchers work with software that allows to go beyond the econometric analysis to enveloped data analysis, however it is essential to start with this tool.
