Abstract:
This work aimed to study the chemical composition, cholinesterase inhibitory activity, and enantiomeric analysis of the essential oil from the aerial parts (leaves and flowers) of the plant Lepechinia paniculata (Kunth) Epling from Ecuador. The essential oil (EO) was obtained through steam distillation. The chemical composition of the oil was evaluated by gas chromatography, coupled to mass spectrometry (GC–MS) and a flame ionization detector (GC-FID). The analyses led to the identification of 69 compounds in total, of which 40 were found in the leaves and 29 were found in the flowers of the plant. The major components found in the oil were 1,8-Cineole, β-Pinene, δ-3-Carene, α-Pinene, (E)-Caryophyllene, Guaiol, and β-Phellandrene. Flower essential oil showed interesting selective inhibitory activity against both enzymes AChE (28.2 ± 1.8 2 µg/mL) and BuChE (28.8 ± 1.5 µg/mL). By contrast, the EO of the leaves showed moderate mean inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), with IC50 values of 38.2 ± 2.9 µg/mL and 47.4 ± 2.3 µg/mL, respectively.

Abstract:
Hedyosmum racemosum (Ruiz & Pav.) G. is a native species of Ecuador used in traditional medicine for treatment of rheumatism, bronchitis, cold, cough, asthma, bone pain, and stomach pain. In this study, fresh H. racemosum leaves of male and female specimens were collected and subjected to hydrodistillation for the extraction of the essential oil. The chemical composition of male and female essential oil was determined by gas chromatography–gas chromatography equipped with a flame ionization detector and coupled to a mass spectrometer using a non-polar and a polar chromatographic column. The antibacterial activity was assayed against five Gram-positive and two Gram-negative bacteria, and two dermatophytes fungi. The scavenging radical properties of the essential oil were evaluated by DPPH and ABTS assays. The chemical analysis allowed us to identify forty-three compounds that represent more than 98% of the total composition. In the non-polar and polar column, α-phellandrene was the principal constituent in male (28.24 and 25.90%) and female (26.47 and 23.90%) essential oil. Other main compounds were methyl chavicol, germacrene D, methyl eugenol, and α-pinene. Female essential oil presented a strong activity against Klebsiella pneumoniae (ATCC 9997) with an minimum inhibitory concentration (MIC) of 500 μg/mL and a scavenging capacity SC50 of 800 µg/mL.

Abstract:
Ocotea quixos (Lam.) Kosterm. is an aromatic tree native to Ecuador, whose leaves are used to prepare aromatic beverages to which different health benefits are attributed. In this study, Ocotea quixos leaves were collected in the Amazon region in different environmental conditions and subjected to hydrodistillation to isolate the essential oil. The collection variables used were type of soil, amount of shade, and height; in addition, the presence of twig and leaf age and moisture were used as variables. Chemical composition was analyzed by means of gas chromatography equipped with a flame ionization detector and gas chromatography coupled to mass spectrometry. A wide variety of chemical compositions were detected in the samples. In total, forty-seven compounds were identified, which represented between 97.17% and 99.89% of the total composition. The constituents were mainly grouped into aliphatic sesquiterpene hydrocarbons (33.03–55.89%), other compounds (8.94–47.83%), and oxygenated monoterpenes (1.97–39.66%). The main constituents were found to be (E)-cinnamyl acetate (5.96–41.65%), (E)-methyl cinnamate (0.38–37.91%), and trans-caryophyllene (8.77–37.02%). The statistical analysis suggested the existence of two essential oil chemotypes and a direct correlation between environmental conditions and chemical composition of the essential oils.

Abstract:
Croton ferrugineus Kunth is an endemic species of Ecuador used in traditional medicine both for wound healing and as an antiseptic. In this study, fresh Croton ferrugineus leaves were collected and subjected to hydrodistillation for extraction of the essential oil. The chemical composition of the essential oil was determined by gas chromatography equipped with a flame ionization detector and gas chromatography coupled to a mass spectrometer using a non-polar and a polar chromatographic column. The antibacterial activity was assayed against three Gram-positive bacteria, one Gram-negative bacterium and one dermatophyte fungus. The radical scavenging properties of the essential oil was evaluated by means of DPPH and ABTS assays. The chemical analysis allowed us to identify thirty-five compounds representing more than 99.95% of the total composition. Aliphatic sesquiterpene hydrocarbon trans-caryophyllene was the main constituent with 20.47 ± 1.25%. Other main compounds were myrcene (11.47 ± 1.56%), β-phellandrene (10.55 ± 0.02%), germacrene D (7.60 ± 0.60%), and α-humulene (5.49 ± 0.38%). The essential oil from Croton ferrugineus presented moderate activity against Candida albicans (ATCC 10231) with an MIC of 1000 μg/mL, a scavenging capacity SC50 of 901 ± 20 µg/mL with the ABTS method, and very strong antiglucosidase activity with an IC50 of 146 ± 20 µg/mL.

Abstract:
The fresh leaves of Coreopsis triloba S.F. Blake, collected at Cerro Villonaco in Loja, Ecuador, were investigated with respect to their essential oil (EO). The chemical composition was determined qualitatively through gas chromatography coupled with mass spectrometry (GC-MS) and quantitatively by gas chromatography coupled with flame ionization (GC-FID), using relative response factors (RRF) based on the enthalpy of combustion. The essential oil contained between 92.5% and 93.4% of monoterpene hydrocarbons, with (E)-β-ocimene being the main component (35.2–35.9%), followed by β-phellandrene (24.6–25.0%), α-pinene (15.3–15.9%), myrcene (10.9–11.0%), sabinene (2.2–2.4%), (Z)-β-ocimene (1.5%), and germacrene D (1.2–1.3%). The enantiomeric distribution of α-pinene, β-pinene, limonene, and germacrene D was also determined. The main components responsible for the aroma were identified through aroma extract dilution analysis (AEDA), a gas chromatography-olfactometry (GC-O) based technique, being α-pinene, β-pinene (0.6%), terpinolene (0.1%), α-copaene (0.1–0.3%), β-phellandrene, and (E)-4,8-dimethyl-1,3,7-nonatriene (0.1–0.2%) the main olfactory constituents according to the decreasing factor of dilution (FD) order. The biological tests showed IC50 inhibition values of 42.2 and 6.8 µg/mL for acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), respectively.

Abstract:
Piper carpunya Ruiz & Pav. is an aromatic shrub native to Ecuador, the leaves of which are used to prepare the traditional beverage Guaviduca. Different health benefits are attributed to the guaviduca beverage, which is consumed as a traditional and folk medicine. In this study, fresh P. carpunya leaves were collected in the winter and summer and subjected to hydrodistillation for the extraction of the essential oil. The guaviduca beverage was prepared by infusion in water and the volatile compounds were isolated by liquid–liquid extraction. Chemical composition and enantioselective analyses were performed by gas chromatography. The antibacterial activity was assayed against Gram-positive and Gram-negative bacteria. The scavenging radical properties of the essential oil was evaluated by 2,2-diphenyl-1-picrylhydryl (DPPH) and 2,2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assays. The acetylcholinesterase inhibitory activity was measured using the spectrophotometric method. The chemical analysis allowed us to identify more than 98% of the compounds in all samples. The main constituent of the essential oil was 1,8-cineole (25.20 ± 1.31%) in P. carpunya collected in winter and (17.45 ± 2.33%) in P. carpunya collected in summer, while in the beverage, there was 14 mg/L. Safrole was identified in the essential oil (PCW 21.91 ± 2.79%; PCS 13.18 ± 1.72%) as well as in the beverage (2.43 ± 0.12 mg/L). Enantioselective analysis was used to investigate the enantiomeric ratio and excess of four chiral components. The essential oil presented a strong activity against Klebsiella pneumoniae with a MIC of 500 μg/mL and a very strong anticholinesterase activity with an IC50 of 36.42 ± 1.15 µg/mL.

Abstract:
The freehold oil and gas lease in Canada has had a perilous and uncertain existence. In the early cases, the courts applied a literal interpretation of the leases, resulting in numerous unexpectedly terminated leases. In recent years, there has been a resurgence of cases involving terminated leases. Modern case law recognizes that the failure of a lease can create liabilities in both tort and restitution, but courts have faced difficulties in dealing with the overlapping compensatory and restitutionary remedies. The modern case law has been heavily criticized, but the authors argue that there is a smaller difference between the overlapping remedies than is commonly supposed when the underlying purpose of restitutionary remedies is examined, and they propose a resolution to the problem of overlapping remedies.

Abstract:
Freehold oil and gas leases seek to reconcile the interests of the lessor and the lessee by providing in the habendum a clause for an initial primary term and "so long thereafter as there is production''. Both Canadian and United States jurisprudence indicate that leases will terminate if production is not' 'in paying quantities''. A test as to whether or not oil or gas is being produced in paying quantities is whether the value of the oil or gas produced exceeds the operating costs. If production fails this test then it must be considered whether a reasonably prudent operator would have continued to produce the well. It is suggested that a slight loss due to a temporary fall in price will not necessarily terminate a lease. But if the well was marginal before the fall in price, or if it extends over a substantial period of time, the holding of the lease by the lessee will most likely be construed as mere speculation. Further, most shut-in clauses do not assist the lessee. Vie clauses generally assume the existence of a well capable of production ' 'in paying quantities''. However, the actual wording must govern and some clauses provide for ' 'economical "or" 'unprofitable'' markets and thereby specifically address the lessee's dilemma.

Bibliography: leaves 651-699. "Through case studies of three emerging economies - Ecuador, Nigeria and Russia - this thesis analyses the factors present to a greater or lesser degree in emerging economies, such as severe foreign indebtedness and the absence of the rule of law, that undermine the effectiveness of the legal system in protecting indigenous peoples from oil exploitation. Having identified these factors, I propose that a dual approach to the protection of indigenous peoples' traditional lands and their environment be adopted, whereby international laws that set out the rights of indigenous peoples and place duties on states in this regard, are reinforced and translated into practice through the self-regulation of the international oil industry through a voluntary code of conduct for oil companies seeking to operate on indigenous peoples' traditional lands."

Abstract:
Changes occurred with the enactment of Law 9478 of 1997, led to some municipalities a financial condition inside, due to the higher inflow of royalties from oil and natural gas. The increase in revenue from royalties from oil and natural gas also ran on the other hand, the extraordinary expansion of the oil sector and the escalation of international prices of raw materials. The sum of these features plus a recipe mean expressive, is an important opportunity to expand investment and to meet the social demands. Royalties are derived from the operation of a nonrenewable resource, which implies that it has a period of exhaustion. For this reason, the literature stresses that his application should be made in capital and human capital. The overall goal of this dissertation is to analyze what were the purposes of royalties on public finances of the federal entities in the period from 1999 to 2011. From the methodology were characterized variables analysis. The analysis model was adopted panel data, which combines cross-sectional data with time series. Based on the tests, it was found that the counties most dependent on royalties increased capital expenditures with increased royalties, both from the perspective as the proportion per capita tax. For personnel costs, it was noted that these were influenced by royalties per capita in all municipalities. Moreover, from the perspective of tax ratio, the tests showed that the more dependent counties, showed a negative relationship. With regard to expenditure on education and culture, it was noted that royalties per capita influenced its formation in considerable part of the municipalities. However, in addressing the proportion fiscal few municipalities were affected, while in the cities most dependent inverse relationship exhibited. As for social spending on health, sanitation, housing and urban development was seen that some of these municipalities increased spending on the inflow of royalties. Finally, in the area of environmental expenditures, only the counties most dependent on royalties increased their spending with increased use.
As transformações ocorridas com a promulgação da lei 9.478, de 1997, propiciaram a alguns municípios brasileiros uma condição financeira privilegiada, em razão do maior ingresso de royalties provenientes da exploração de petróleo e gás natural. A elevação das receitas de royalties de petróleo e gás natural também decorreu, por outro lado, pela extraordinária expansão do setor petrolífero e pela escalada dos preços internacionais da matéria prima. A soma desses recursos além de significar uma receita expressiva, é uma importante possibilidade de ampliação dos investimentos e para o atendimento das demandas sociais. Os royalties são provenientes da exploração de um recurso natural não renovável, o que implica dizer que ele possui um prazo de esgotamento. Por esta razão, a literatura reforça que sua aplicação deve ser feita em bens de capital e capital humano. O objetivo geral desta dissertação é analisar quais foram os efeitos da aplicação dos royalties sobre as finanças públicas dos entes federativos no período de 1999 a 2011. A partir da metodologia foram caracterizadas as variáveis de análise. O modelo de análise adotado foi o de dados em painel, que combina dados de corte transversal com séries temporais. Com base nos testes, foi verificado que os municípios mais dependentes dos royalties elevaram as despesas de capital com o aumento dos royalties, tanto pela ótica per capita como pela proporção fiscal. Para as despesas com pessoal, observou-se que estas foram influenciadas pelos royalties per capita em todos os municípios. Ademais, pela ótica da proporção fiscal, os testes apontaram que os municípios mais dependentes, exibiram relação negativa. No que se refere às despesas com educação e cultura, notou-se que os royalties per capita influenciaram sua formação em parte considerável dos municípios. Porém, na abordagem da proporção fiscal poucos municípios foram influenciados, ao passo em que os municípios mais dependentes exibiram relação inversa. Já para às despesas sociais com saúde, saneamento, habitação e urbanismo foi visto que parte dos municípios aumentaram estas despesas com o ingresso de royalties. Por fim, na área ambiental dos gastos, apenas os municípios mais dependentes de royalties elevaram suas despesas com o aumento do recurso.

The federal decentralization promoted by the Constitution of 1988 raised the Brazilian municipalities to the important role in the dissemination of public policies. Once they are closest to the population, the decisions made at the municipal level are readily perceived by users and citizens. On the other hand, the social demands and the management of the administrative structure need efficient financial management and a constant search for resources. Additionally, the 9.478/97 Act, which amended the mode of distribution of oil revenues, brought to some municipalities, a new frontier of resources available by the distribution of oil royalties. Given this new frontier of resources, one wonders whether there is not relaxation in fiscal effort and an increasing inefficiency in the management of the administrative machinery by the benefited municipalities. The aim of this work is verify if petroleum revenues cause distortions in the way municipalities run their fiscal effort, that is, if the oil royalties contribute to increase inefficiencies in the municipalities involved in their search for the own revenues and their expense management. For this work, we selected 56 municipalities of the State of S??o Paulo which have been received the distribution of oil revenues during the period between the years 2005 to 2012. The efficiency of municipalities was obtained from a non-parametric production frontier model, the Data Envelopment Analysis - DEA, creating a ranking of the S??o Paulo municipalities which received oil royalties. Given the distribution rules of oil royalties imposed by the regulatory framework, the results showed the values distributed to S??o Paulo municipalities have great variability and has been showed relevant only in a few municipalities. There was no significant difference in the tax effort of the municipalities affected by the variable oil royalites. However, several factors related to municipal management indicated that such rents can contribute to increase inefficiencies in the management of municipal administrative machinery
A descentraliza????o federativa, promovida pela Constitui????o Federal de 1988, elevou os Munic??pios brasileiros ao importante papel na dissemina????o das pol??ticas p??blicas. Por estarem mais pr??ximos da popula????o, as decis??es realizadas na esfera municipal s??o prontamente percebidas pelos usu??rios e pelos cidad??os. Por outro lado, as demandas sociais e a administra????o da m??quina administrativa necessitam de uma gest??o financeira eficiente e uma constante busca por recursos. Adicionalmente, a Lei 9.478/97, que alterou o modo de distribui????o das rendas do petr??leo, trouxe, para alguns Munic??pios, uma nova fronteira de recursos, disponibilizada pela distribui????o dos royalties de petr??leo. Diante dessa nova fronteira de recursos, questiona-se se n??o h??, por parte dos Munic??pios beneficiados, um relaxamento no esfor??o fiscal e o aumento da inefici??ncia na gest??o da m??quina administrativa. Neste trabalho objetiva-se verificar se as rendas do petr??leo provocam distor????es na forma como os Munic??pios s??o conduzidos em seu esfor??o fiscal, ou seja, se os royalties de petr??leo contribuem para o aumento das inefici??ncias nos Munic??pios envolvidos em sua busca pelas receitas pr??prias e na sua gest??o de despesas. Para a realiza????o deste trabalho, foram selecionados 56 Munic??pios do Estado de S??o Paulo, contemplados pela distribui????o das rendas do petr??leo durante o per??odo compreendido entre os anos de 2005 a 2012.

Abstract:
Este estudo apresenta uma avaliação da atuação do controle externo exercido pelos Tribunais de Contas na aplicação de royalties e participação especial do petróleo nos municípios brasileiros, compensações financeiras devidas pela exploração de reservas de petróleo no território brasileiro e transferidas pela União. Ao associar os conceitos de federalismo fiscal, incrementalismo, teoria das externalidades, transparência, accountability, rendas do petróleo e o sistema de orçamento público, sob a ótica da relação entre planejamento e controle, buscou estabelecer as bases teóricas para as análises realizadas, que objetivaram mapear as políticas públicas eventualmente financiadas com esses recursos, levantar aspectos da governança pública relacionados à aplicação desses recursos, identificar os instrumentos de controle externo utilizados e analisar os pareceres prévios do controle externo sobre as contas anuais dos municípios beneficiários. Nesse sentido, a partir de pesquisa aplicada, os dados coletados foram submetidos a tratamento quantitativo, fase denominada de 1º estágio, relacionados à estimativa de receitas, transferências intergovernamentais e o custeio de despesas correntes, em particular, de despesas com pessoal e encargos, disponibilizados pelos municípios beneficiários aos tribunais de contas estaduais, conforme determinação da Lei de Responsabilidade Fiscal. Como resultados, foram identificados a baixa qualidade das estimativas de receitas, a representativa evolução da participação das rendas do petróleo na receita total realizada e no custeio de despesas de pessoal e encargos nos orçamentos anuais. No 2º estágio da pesquisa, de abordagem qualitativa, via análise de conteúdo dos pareceres prévios emitidos pelo controle externo sobre as contas anuais dos municípios beneficiários, em confronto com os resultados obtidos no 1º estágio da pesquisa, foi realizada avaliação da atuação do controle externo, sob aspectos relacionados à conformidade legal, à observância de aspectos relacionados à transparência e accountability e à oportunidade de aperfeiçoamento da administração pública. Como resultado da avaliação, identificou-se que a utilização de rendas do petróleo no custeio de despesas de pessoal e encargos tem o aval do Tribunal de Contas do Estado do Rio de Janeiro, que essas rendas não estão associadas formalmente à execução de qualquer política pública específica, que não há avaliação do controle externo quanto às estimativas e destinação dessas receitas, que não há fundamentação teórica que suporte às análises dos pareceres prévios emitidos e que não há a emissão de recomendações de aprimoramento ou criação de legislação municipal que regulamente a aplicação e a destinação desses compensações financeiras, diante da omissão da legislação federal que as instituiu.
This study presents an evaluation of the external control exercised by the Courts of Auditors in the application of royalties and special oil participation in Brazilian municipalities, financial compensation due for the exploitation of oil reserves in Brazilian territory and transferred by the Union. By associating the concepts of fiscal federalism, incrementalism, externality theory, transparency, accountability, oil revenues, and the public budget system, from the point of view of the relationship between planning and control, sought to establish the theoretical bases for the analyzes carried out, which aimed to map the public policies that have been financed with these resources, to raise aspects of public governance related to the application of these resources, to identify the external control instruments used and to analyze the previous external control opinions on the annual accounts of the beneficiary municipalities. In this sense, based on applied research, quantitative treatment of the collected data has been made, phase denominated 1st stage, related to the estimation of revenues, intergovernmental transfers and the costing of current expenses, in particular, expenses with personnel and charges, made available by the Beneficiary municipalities to the state accounts courts, as determined by the Fiscal Responsibility Law. As a result, the low quality of revenue estimates, the representative evolution of the share of oil revenues in total revenue and the cost of personnel expenses and charges in annual budgets were identified. In the 2nd stage of the research, characterized by a qualitative approach, through content analysis of previous opinions issued by the external control over the annual accounts of the beneficiary municipalities, in comparison with the results obtained in the first stage of the research, an evaluation of the performance of the external control was performed, regarding aspects related to legal compliance, compliance with aspects related to transparency and accountability, and the opportunity to improve public administration. As a result of the evaluation, it was identified that the use of oil revenues in the costing of personnel expenses and charges is endorsed by the Court of Auditors of the State of Rio de Janeiro, that these revenues are not formally associated with the execution of any public policy, that there is no evaluation of external control as to the estimates and allocation of these revenues, that there is no theoretical basis that supports the analysis of the prior opinions issued and that there is no issuance of recommendations for improvement or creation of municipal legislation that regulates the application and allocation of these financial compensation, due to the omission of the federal legislation that instituted them.
