This paper examines and analyses the impacts of the reformed CAP as well as the decisions of the new round of negotiations for the olive oil and cotton sectors in the European Union. The aim of this study is to estimate changes in supply (agricultural supply plus intermediate demand and final production), demand (consumption), price and stock formation (import, export, beginning and ending stocks, national price formation) for both the olive oil and cotton sectors. The model designed for this purpose is partial equilibrium and policy oriented. The objectives of this model are to estimate changes in the production and consumption of the two products concerned, to determine how the reformed CAP and the new round of negotiations of the WTO affect these two sectors to analyse the evolution of export and import volumes, and finally to determine how this evolution will influence the welfare situation of the olive and cotton sectors.

A number of US states, counties and municipalities have responded to the public health and environmental concerns surrounding fracking by imposing bans or moratoriums on unconventional oil and gas drilling. These restrictions have, in recent years, given rise to litigation challenges by oil and gas companies and by property owners deprived of potential revenues. The current article begins by examining precisely who has litigated. Have large companies dominated or is it mostly smaller independents? Is there a difference in litigation rates between private and public companies? The article then considers how Hirschman’s ideas of exit, voice and loyalty might apply in the context of bans and moratoriums and further explores some of the factors that may have driven litigation in the area.

The present paper reports phase equilibrium experimental data for two systems composed by peanut oil or avocado seed oil + commercial oleic acid + ethanol + water at 298.2 K and different water contents in the solvent. The addition of water to the solvent reduces the loss of neutral oil in the alcoholic phase and improves the solvent selectivity. The experimental data were correlated by the NRTL and UNIQUAC models. The global deviations between calculated and experimental values were 0.63 % and 1.08 %, respectively, for the systems containing avocado seed oil. In the case of systems containing peanut oil those deviations were 0.65 % and 0.98 %, respectively. Such results indicate that both models were able to reproduce correctly the experimental data, although the NRTL model presented a better performance.

Chen LM, Zhao J, Musa-Aziz R, Pelletier MF, Drummond IA, Boron WF. Cloning and characterization of a zebrafish homologue of human AQP1: a bifunctional water and gas channel. Am J Physiol Regul Integr Comp Physiol 299: R1163-R1174, 2010. First published August 25, 2010; doi:10.1152/ajpregu.00319.2010.-The mammalian aquaporins AQP1, AQP4, and AQP5 have been shown to function not only as water channels but also as gas channels. Zebrafish have two genes encoding an AQP1 homologue, aqp1a and aqp1b. In the present study, we cloned the cDNA that encodes the zebrafish protein Aqp1a from the 72-h postfertilization (hpf) embryo of Danio rerio, as well as from the swim bladder of the adult. The deduced amino-acid sequence of aqp1a consists of 260 amino acids and is 59% identical to human AQP1. By analyzing the genomic DNA sequence, we identified four exons in the aqp1a gene. By in situ hybridization, aqp1a is expressed transiently in the developing vasculature and in erythrocytes from 16 to 48 h of development. Later, at 72 hpf, aqp1a is expressed in dermal ionocytes and in the swim bladder. Western blot analysis of adult tissues reveals that Aqp1a is most highly expressed in the eye and swim bladder. Xenopus oocytes expressing aqp1a have a channel-dependent (*) osmotic water permeability (P(f)*) that is indistinguishable from that of human AQP1. On the basis of the magnitude of the transient change in surface pH (Delta pHS) that were recorded as the oocytes were exposed to either CO(2) or NH(3), we conclude that zebrafish Aqp1a is permeable to both CO(2) and NH(3). The ratio (Delta pHS*)CO2/P(f)* is about half that of human AQP1, and the ratio (Delta pHS*)NH3/P(f)* is about one-quarter that of human AQP1. Thus, compared with human AQP1, zebrafish Aqp1a has about twice the selectivity for CO(2) over NH(3).

The aim of this study was to investigate the effect of chronic treatment with C. multijuga oil on Ehrlich tumor evolution. C multijuga was fractionated in a KOH impregnated silica gel column chromatography to give three distinct fractions, i.e., hexanic, chloroformic, and methanolic, mainly composed by hydrocarbon sesquiterpenes, oxygenated sesquiterpenes and acidic diterpenes, respectively. Results demonstrated that the C multijuga oil, the hexanic, and chloroformic fractions did not develop toxic effects. The oil, hexanic and chloroformic fractions (doses varying between 100 and 200 mg/kg) showed antineoplasic properties against Ehrlich ascitic tumor (EAT) and solid tumor during 10 consecutive days of treatment inhibiting ascitic tumor cell number, reverting medulla and blood cell counts to values similar to control group, and inhibiting the increase on several inflammatory mediators (total protein, PGE(2), nitric oxide, and TNF) on ascitic fluid. The treatment also inhibited the increase in paw volume on tumor-inoculated mice. In conclusion, C. multijugo as well as its fractions demonstrated antineoplasic effect even after oral administration confirming its use by traditional medicine. (C) 2008 Elsevier Ireland Ltd.

A method for the determination of pesticide residues in water and sediment was developed using the QuEChERS method followed by gas chromatography - mass spectrometry. The method was validated in terms of accuracy, specificity, linearity, detection and quantification limits. The recovery percentages obtained for the pesticides in water at different concentrations ranged from 63 to 116%, with relative standard deviations below 12%. The corresponding results from the sediment ranged from 48 to 115% with relative standard deviations below 16%. The limits of detection for the pesticides in water and sediment were below 0.003 mg L(-1) and 0.02 mg kg(-1), respectively.

REPETRO, the special tax regime for importing and exporting goods for the exploration and drilling of oil and gas, aims at bringing foreign assets to Brazil enjoying a suspension or even an exemption of taxes, so that Brazilian industry may profit from about 8 billion American dollars in investments. The creation of normative devices as well as the management of the REPETRO model are under the exclusive responsibility of the Brazilian Internal Revenue Services. REPETRO was created in 1999 and is composed of the following customs treatments: importation of goods with suspension of taxes by use of the drawback special regime, suspension mode for national exporting industry; exportation with fictitious exit for the national industry; temporary admission of goods or assets used in oil exploration and production, attending to the needs of both the national and foreign market. Considering the inability of the Brazilian government in restructuring its foreign trade model so that a strong investment in technology could provide for the sector¿s needs, we must ask how we can change REPETRO to help the various companies in the oil business? The issue is very important for one of our main economic activities, though not enough studied. The energy sector has a strategic importance for the development and the economic independence of any country. The winds of globalization lead Brazil to open its economy in the last decade and the national policy for exploration and drilling (E&D) was altered. The government created a new agency dedicated to market control and energy policies, the National Agency for Oil and Biofuels (ANP). With the opening of the market, Petróleo Brasileiro S.A. - Petrobras, the Brazilian giant, lost the monopoly of the oil business. The P-50 Platform, with a capacity for 180,000 barrels per day, was imported based on REPETRO. When it began operating on April 21st, 2006, Brazil achieved self-sufficiency in oil production. The present work intends to estimate the main variables affecting the importation and exportation of goods and assets for E&D, showing how REPETRO works. We also intend to look at the results yielded by the REPETRO model for the development of the production of oil and gas in Brazil, as well as show proposals for its modernization. It has been established that even though since its implementation the REPETRO model has brought fiscal advantages through the reduction of tax costs relating to foreign commerce operations and the incentive of investments in the E&D area with the increase in the national oil production there remain the following limitations: lack of preparation and of knowledge of the model; lack of adjustement of the model to the reality of actitity of E&D of oil and gas; taxes over the pre-operational stage or investment in oil production stage; non-allowance of full access by the national industry to the supply of goods and products relating to the industrialization of goods allowed by REPETRO; other fiscal and administrative difficulties. We conclude that the REPETRO model is important for the development of the area of E&D of oil and gas, but not completely effective. It is necessary to change it or create a new model based on a new perspective of the customs treatment of the activities of exploration and production, minimizing administrative procedures relating to the operations of exportation and importation.

Neste trabalho, utilizamos informações do mercado de credit default swap para medir os principais componentes do spread das empresas do setor de óleo e gás. Utilizando cerca de 20 empresas da indústria de óleo e gás composta por companhias de diversos ratings e aproximadamente 80 bonds, os resultados mostraram que a maior parte do spread corporativo do setor decorre do risco de inadimplemento. Também encontramos que o componente do spread não relacionado ao default é fortemente associado a algumas medidas de liquidez do mercado de bonds, sugerindo que a liquidez tem um papel importante na avaliação de títulos de renda fixa. Por outro lado, não encontramos evidências da importância de fatores tributários na explicação do componente do spread não relacionado à inadimplência.

O objetivo desta dissertação é verificar a aderência de atividades desenvolvidas por uma empresa prestadora de serviços de base tecnológica, atuante na área de petróleo, gás e energia, a Pipeway Engenharia Limitada , aos conceitos teóricos do Paradigma Novas Empresas Internacionais - NEI (RENNIE,1993; MCDOUGALL et. Al., 1994) durante seu processo de internacionalização. Trata-se de um estudo que assume, para o autor, uma relevância significativa, já que a compreensão do processo de internacionalização da empresa analisada, considerada de porte pequeno, permitirá que suas atividades profissionais venham a ser desenvolvidas com melhor compreensão das necessidades, exigências e soluções que esse tipo de empresa requer para a sua internacionalização. Para atingir o objetivo proposto, a metodologia utilizada foi o estudo de caso único em função, assim definido, por um lado, pelo fato de não existir no Brasil uma quantidade importante de empresas com características semelhantes à estudada e, por outro, por ser um método que se aplica, quando se deseja ter respostas a questões, tais como: “como” e “por que”, permitindo a compreensão de fenômenos individuais. Para compreender melhor a evolução do setor de serviços nos mercados internacionais foi necessário fazer um estudo sucinto, baseado em análises documental e bibliográfica, para determinar a evolução e importância do mesmo como fator gerador de riqueza, inovação e sustentação do desenvolvimento empresarial. Considerando que a empresa analisada foca seu trabalho no segmento de petróleo e gás, para melhor compreensão desse segmento econômico, foi realizada análise tanto de âmbito nacional como internacional, de sua atual conformação e situação, pois, diferentemente de outros segmentos internacionais, as empresas que neles desenvolvem suas atividades se deparam com mercados mais abertos e globalizados e essas características têm impacto significativo na empresa analisada. A junção da primeira com a segunda análise permitiu avaliar o grau de competitividade e demais parâmetros a que a empresa estudada teve que atender para ser considerada ou não um Novo Empreendimento Internacional. Posteriormente, com os preceitos metodológicos de estudo de caso, acrescidos dos dados obtidos na pesquisa documental e entrevistas com a alta gerência da empresa, foi efetuado um relato historiográfico da evolução do processo de internacionalização da empresa, destacando os eventos e fatos que possibilitaram verificar a aderência, ou não, aos pressupostos do paradigma NEI. Por fim, foi investigada a evolução internacional da empresa à luz dos critérios de análise, diretamente relacionados com princípios do Paradigma NEI, o que permitiu no capitulo seguinte, vinculado às conclusões em forma empírica, que o processo de internacionalização da Pipeway responde na sua totalidade às características do Paradigma NEI. Um exemplo é a data de início da internacionalização e relação entre as receitas de exportação e faturamento total. Também são apresentadas sugestões para o desenvolvimento de pesquisas futuras, aprimoramento dos programas governamentais de apoio ao processo de internacionalização de Pequenas Empresas e desempenho profissional do autor

This paper considers challenges of Human Resource Management (HRM) in Open Innovation processes. It examines which strategies managers used to overcome these problems in the case of the Brazilian Oil and Gas company Petrobras. By conducting an inductive case study it develops a contextual model based on the use of grounded theory. It argues that the most important categories were to overcome problems of (a) the interpersonal relationship, (b) power shifting inside the organization, and (c) making people more valuable to the organization and shows how managers tackled these challenges. It contributes with a deep analysis of HRM challenges in Open Innovation that is important for a better understanding of management problems that can come along with Open Innovation processes.

We estimate the effects of unconditional (full fiscal decentralization) versus conditional (partial fiscal decentralization) block grants on local public spending in Brazilian municipalities. Our results suggest that the effect of unconditional and conditional transfers do not differ statistically. Their combination promotes a full crowding-in effect on aggregate public spending — i.e., for $1 of unconditional and conditional grant receipts; we find $1 of additional local public expenditures, greater than the corresponding effect of local income, providing further evidence for the flypaper effect. Moreover, the effect of unconditional transfers on education (health) spending is smaller than the effect of conditional education (health) transfers but greater than the corresponding effect of local income. We consider four strategies to identify causal effects of federal grants and the local income on fiscal responses regarding Brazilian local governments: (i) a fuzzy regression discontinuity design, (ii) Redistributive rules of education funds, (iii) Oil and Gas production, and (iv) Rainfall deviations from the historical mean.

Após uma sequência histórica de ciclos econômicos no Brasil, desde o final da década de 90, o país presencia a abertura do setor do Petróleo ligado à descoberta do pré-sal e o volume imensurável das reservas naturais. Esse marco pôde determinar o início de um dos mais relevantes e diversificados ciclos de industrialização na história econômica do Brasil. Mesmo nesse ramo de negócio, um mercado de gigantes, de multinacionais, de grandes players com estratégias inovadoras e múltiplos know-how's insubstituíveis, é fato conhecido, principalmente para os profissionais dessa seara, que muitas empresas de petróleo possuem inúmeros fatores críticos com urgente necessidade de melhoria. O objetivo principal desta dissertação é fazer inicialmente uma breve análise estratégica e mercadológica da subsidiária brasileira de um grupo multinacional do ramo de Petróleo e Gás especializado em tecnologia de fluidos de perfuração de poços de petróleo, com presença em mais de vinte países. Após imersão no contexto, realizar a análise detalhada de um processo em especial, a primeira vista sem importância, que ao ser estudado, monitorado e mapeado, pôde ser ajustado, redesenhado e implementado, apresentando ganhos substanciais para a corporação relacionados à competitividade e lucratividade.
