Previous issue date: 2015-02-19 / Nenhuma / O presente estudo objetiva analisar como foram tratadas, no âmbito societário e fiscal, as reorganizações societárias conhecidas por drop down. Bastante comuns nos Estados Unidos, essas operações se caracterizam pelo aumento de capital que uma empresa produz em outra, ao transferir bens, direitos e/ou obrigações em troca de participação societária com controle acionário. Ademais, se assemelha à cisão em alguns aspectos, mas sem a redução do capital social ou a extinção da empresa cindida, o que induz alguns teóricos nacionais a denominarem como cisão branca. A essência do drop down - e consequentemente, a estratégia utilizada pelas empresas que optam por esse modelo de reestruturação societária - focaliza no core business, ou seja, concentra-se na atividade principal. A metodologia de pesquisa adotada para a construção desta dissertação, portanto, se estruturou em bases documentais, na qual constassem temas ligados à reestruturação ou à reorganização societária por intermédio da combinação de negócios que envolvessem as operações de drop down. Assim, o estudo pôde contribuir para a divulgação de novas formas de reorganizações societárias e sinalizar ao profissional contábil as formas de registros da operação e, posteriormente, auxiliar na divulgação das demonstrações contábeis. Os resultados obtidos revelaram que, mesmo não sendo muito conhecida no país, a operação de drop down vem ocorrendo como meio de reestruturação societária em empresas brasileiras. Também por meio da análise dos resultados, concluiu-se que, para as Companhias investigadas e/ou avaliadas pelos órgãos estaduais e do mercado de valores, a operação não foi objeto de questionamento por parte deles, haja vista que tão somente mensuraram como foram tratadas contábil e fiscalmente nas organizações selecionadas. Nas análises das empresas que não evidenciaram processos de avaliação pelos órgãos estaduais e pelo mercado de valores, identificou-se o foco no core business - a saber, a concentração de esforços nas atividades principais e a associação das empresas com as atividades afins. Igualmente, se observou se elas atentaram para as devidas contabilizações previstas nos pronunciamentos contábeis e nos registros contábeis da operação pretendida. / This study aims to analyze how corporate reorganizations known as drop down were treated in the corporate and fiscal scope. Quite common in the United States, these operations are characterized by the capital increase a company produces in another one, transferring assets, rights and/or obligations in exchange for share participation with share control. Moreover, in some aspects resembles a divestiture but without the reduction of equity capital or the termination of the divided company, which induces some national theorists call it white divestiture. The essence of drop down - and consequently the strategy used by companies that choose this corporate restructuring model - focuses on the core business, ie, focuses on the main business. The methodology adopted for the construction of this work, therefore, was built in document databases in which see covered in topics related to restructuring or reorganization through the business combination involving the drop down operations. Thus, the study could contribute to the spread of new forms of corporate restructuring and indicate to accounting professionals ways to record operations and, subsequently, assist in the disclosure of financial statements. The results revealed that, although not very known in the country, the drop-down operation has taken place as a means of corporate restructuring in Brazilian companies. Also by analyzing the results, it was concluded that, for companies investigated and/or evaluated by state agencies and the stock market, the operation was not a subject of questioning from them, given that only measured as they have been dealt accounting and fiscally in selected organizations. In the analyzes of companies which had no assessment procedures by state agencies and securities market, it was identified the focus on core business - namely, the concentration of efforts on core activities and the association of companies with similar activities. Likewise, it was observed if they attempted to the appropriate accountings provided in financial statements and accounting records of the intended operation.

Previous issue date: 2012-05-28 / Fundação de Amparo à Pesquisa do Estado de Goiás - FAPEG / OBJECTIVE: To describe tuberculosis treatment rates of cure, failure and default of
a self administered regimen, with rifampin, isoniazid, pyrazinamide and ethambutol
in the first two months of treatment followed by isoniazid and rifampcina in the four
last months (2RHZE/4RH) in four-drug fixed-dose combination (FDC), implemented
in Brazil since 2010 to replace a regimen of separately administered rifampicin,
isoniazid and pyrazinamide in the first two months of treatment followed by
isoniazid and rifampcina for four months (2RHZ/4RH). METHODS: Descriptive
study using prospectively collected data from medical records of TB cases, older
than18 years of age undergoing treatment with 2RHZE/4RH in two units of primary
health care in the metropolitan area of Goiânia. RESULTS: The study included 40
cases of TB. The cure rate was 67.5% (27/40), the abandonment was 17.5% (7/40)
and there were no cases of failure. There was reports of adverse reactions in 47%
(19/40) of the cases. Of these, 87% were mild and 13% were moderate. There was no
need for change or suspension of the scheme. CONCLUSIONS: The cure rate in
FDC 4RHZE/2RH scheme under self-administered regimen was similar to historical
rates of cure with 2RHZ/4RH. The default rate in the sample studied was much
higher than the rate recommended as appropriate (up to 5%). / INTRODUÇÃO: O esquema de tratamento da TB tem alta eficácia em torno de 95%
e com possibilidade de cura de aproximadamente 100% dos casos e reduz
rapidamente a transmissão, e assim pode-se reduzir a incidência da doença. Embora a
distribuição da medicação seja gratuita em todo país pelo Sistema Único de Saúde, a
efetividade do tratamento da TB varia muito nos diferentes locais. JUSTIFICAVA:
Conhecer as taxas de sucesso de tratamento ,falência e abandono além de verificar a
segurança do tratamento da TB com 4 medicamentos em apresentação dose fixa
combinada.
OBJETIVO: Descrever as taxas de cura, falência e abandono do tratamento da
tuberculose com o esquema básico com rifampicina, isoniazida, pirazinamida e
etambutol nos dois primeiros meses de tratamento seguidos de isoniazida e
rifampcina por quatro meses (2RHZE/4RH), sob forma de comprimidos em dose fixa
combinada (DFC), em regime auto administrado implementado no Brasil desde
2010, em substituição ao esquema utilizando cápsulas e comprimidos com
rifampicina, isoniazida e pirazinamida nos dois primeiros meses de tratamento,
seguidos de isoniazida e rifampcina por quatro meses (2RHZ/4RH). MÉTODOS:
Estudo descritivo utilizando dados secundários coletados prospectivamente de
prontuários de casos de TB, maiores de 18anos, submetidos ao tratamento com
esquema básico para tuberculose, em duas Unidades Básicas de Saúde da região
metropolitana de Goiânia. RESULTADOS: Foram incluídos no estudo 40 casos de
TB. A taxa de cura foi de 67,5% (27/40), a de abandono de 17,5% (7/40) e a não
ocorreram casos de falência. Houve relato de reações adversas em 47% (19/40) num
total de 31 ocorrências. Dessas, 87% foram leves e 13% moderadas. Em nenhum
caso houve necessidade de mudança ou suspensão do esquema. CONCLUSÕES: A
taxa de cura do esquema 4RHZE/2RH em DFC sob regime autoadministrado foi
semelhante às taxas históricas do tratamento com 2RHZ/4RH. A taxa de abandono na
amostra estudada foi superior a taxa preconizada como adequada (até 5%).

Combinações de doses de nitrogênio e potássio para o capim-mombaça. / Nitrogen and potassium combinations to mombaça grass.José Lavres Junior 24 January 2002 (has links)
Com o objetivo de avaliar os efeitos de combinações de doses de nitrogênio e potássio nos atributos bioquímicos, fisiológicos, produtivos e nutricionais do Panicum maximum Jacq. cv. Mombaça cultivado em solução nutritiva e utilizando sílica moída como substrato, conduziu-se um experimento em casa-de-vegetação no período de novembro de 2000 a fevereiro de 2001. Foi empregado o desenho experimental composto central modificado de um esquema fatorial 52 incompleto, perfazendo um total de 13 combinações das doses de nitrogênio e potássio (28N-19,5K; 28N-234K; 28N-429K; 112N-117K; 112N-312K; 210N-19,5K; 210N-234K; 210N-429K; 336N-117K; 336N-312K; 462N-19,5K; 462N-234K e 462N-429K), as quais foram distribuídas segundo o delineamento experimental de blocos ao acaso, com quatro repetições. Aos 36 dias após o transplante das plântulas procedeu-se o primeiro corte das plantas e o material da parte aérea foi separado em folhas emergentes, lâminas das duas folhas recém-expandidas, lâminas das folhas maduras e colmos mais bainhas. Aos 29 dias após o primeiro corte realizou-se a segunda colheita, procedendo-se a separação da parte aérea como no primeiro corte e sendo as raízes separadas da sílica e lavadas. Os resultados evidenciaram interação significativa (P<0,01) entre as doses de nitrogênio e potássio na produção de massa seca da parte aérea no primeiro e segundo cortes e das raízes do capim-Mombaça, na área foliar em ambos os cortes, no teor de clorofila nas lâminas de folhas recém-expandidas na ocasião do primeiro crescimento, no número de perfilhos e folhas verdes expandidas na ocasião do segundo corte, na atividade da enzima redutase do nitrato no primeiro crescimento e no comprimento total e superfície total de raízes. O teor de clorofila foi significativamente (P<0,01) influenciado pelas doses de nitrogênio na ocasião do segundo corte e as doses de nitrogênio (P<0,01) e potássio (P<0,05) promoveram efeitos significativos no perfilhamento do capim-Mombaça por ocasião do primeiro corte. No primeiro corte das plantas a produção de folhas verdes expandidas mostrou significância (P<0,01) para o componente quadrático da regressão em função do suprimento de nitrogênio na solução e significância (P<0,01) para o componente linear da regressão em função do suprimento de potássio na solução. A atividade enzimática da redutase do nitrato variou significativamente (P<0,01) somente para as doses de nitrogênio por ocasião do segundo corte das plantas. As concentrações de nitrogênio e potássio nos componentes da parte aérea nos dois períodos de crescimento das plantas e nas raízes foram influenciadas pelo fornecimento das doses de nitrogênio e de potássio na solução nutritiva. / With the objective of evaluating the effects of nitrogen and potassium on biochemical and physiological parameters on mineral nutrition and yield of Panicum maximum Jacq. cv. Mombaça. An experiment was carried out in a greenhouse from November 2000 to February 2001. The forage was grown in nutrient solution using ground quartz as substrate. The experimental arrange used was an incomplete 52 factorial of nitrogen and potassium and the 13 combinations between nitrogen and potassium (28N-19.5K; 28N-234K; 28N-429K; 112N-117K; 112N-312K; 210N-19.5K; 210N-234K; 210N-429K; 336N-117K; 336N-312K; 462N-19.5K; 462N-234K and 462N-429K) were obtained according to design points of the modified central composite nonrotatable design that was set in a randomized block design, with four replications. Plants were first harvested 36 days after transplanting and the plant tops was separated in emergent leaves (EL), lamina of recently expanded leaves (RL), lamina of mature leaves (ML) and stems plus sheaths (SS). Twenty nine days after the first harvest the plants were harvested again and the plant tops were separated as in the first harvest and roots were also collected and washed. Results showed nitrogen X potassium interaction was significant (P<0.01) for the plant tops dry matter yield on the first and the second harvests and roots dry matter, leaf area, SPAD values on RL on the first harvest, plant tillering and number of green expanded leaves on the second harvest, nitrate reductase activity on the first harvest, total root length and total root surface. The SPAD values were significantly (P<0.01) changed at the second harvest by nitrogen rates and, tillering was significantly affected by nitrogen (P<0.01) and potassium rates (P<0.05) at the first harvest. The number of green expanded leaves at the first harvest was significantly (P<0.01) influenced by the supply of nitrogen and significantly (P<0.01) affected by potassium rates. At the second plant growth nitrogen rates significantly (P<0.01) influenced nitrate reductase activity. Nitrogen and potassium concentrations in plant tops and roots at both growth periods were affected by nitrogen and potassium rates in the nutrient solution.

Forecast Combination with Multiple Models and Expert CorrelationsSoule, David P 01 January 2019 (has links)
Combining multiple forecasts in order to generate a single, more accurate one is a well-known approach. A simple average of forecasts has been found to be robust despite theoretically better approaches, increasing availability in the number of expert forecasts, and improved computational capabilities. The dominance of a simple average is related to the small sample sizes and to the estimation errors associated with more complex methods. We study the role that expert correlation, multiple experts, and their relative forecasting accuracy have on the weight estimation error distribution. The distributions we find are used to identify the conditions when a decision maker can confidently estimate weights versus using a simple average. We also propose an improved expert weighting approach that is less sensitive to covariance estimation error while providing much of the benefit from a covariance optimal weight. These two improvements create a new heuristic for better forecast aggregation that is simple to use. This heuristic appears new to the literature and is shown to perform better than a simple average in a simulation study and by application to economic forecast data.

The Effect of <em>Lactobacillus helveticus</em> and <em>Propionibacterium freudenreichii</em> ssp. <em>shermanii</em> Combinations on Propensity for Split Defect in Swiss CheeseWhite, Steven R. 01 May 2002 (has links)
One of the least controlled defects in Swiss cheese is development of splits. Split defect is characterized by fissures or cracks in the body of the cheese that can be as short as 1 cm in length or long enough to span a 90-kg block. This defect appears during refrigerated storage after the cheese is removed from the warm room. Swiss cheese with splits is downgraded because it is unsuitable for use on high-speed slicing equipment (up to 1,000 slices per minute).
A 2x2x2 factorial experiment was used to determine the effect of different commercial Lactobacillus helveticus starters combined with commercial gas-forming strains of Propionibacterium freudenreichii ssp. shermanii on the occurrence of split defect in Swiss cheese. Two strains of L. helveticus recommended for Swiss cheese manufacture were used along with two strains of P. freudenreichii ssp. shermanii. The same strain of Streptococcus thermophilus was used in all treatments.
To investigate the influence of seasonal variations in milk supply, eight vats were made in the summer and eight vats were made in the winter, each producing five 90-kg blocks of cheese. Each 90-kg block of cheese was cut into twenty-four 4-kg blocks, and each 4-kg block was graded based on the presence of splits. If splits were present, the cheese was downgraded from A to C grade.
Only small variations were found in the composition of cheeses made during the same season. There were no correlations between cheese moisture, pH, fat, protein, calcium, lactose contents, D/L lactate ratio, or protein degradation that could be used to predict the amount of splits present after 90 d of storage.
The extent of split formation was influenced by both the L. helveticus and P. freudenreichii ssp. shermanii cultures used. In this study, we were able to show a fivefold reduction in downgraded cheese through proper culture selection from 90% to 14% in the summer cheese. Even though less than 6% of the cheese split in the winter, the culture effect was nonetheless repeatable with a similar reduction through culture selection from 6% to 1% in winter cheese. Split formation also increases with storage time. If a cheese has a tendency to split, there will be a higher percentage of downgraded cheese the longer it is kept in storage.

The Mechanisms of Hydride Exchange, Organic Combination and Displacement ReactionsHao, Weifang 01 May 2012 (has links)
The primary aim of this dissertation was to seek the answer to the question: “Is the single transition-state model appropriate for the fundamental reactions in organic chemistry?” The goal was accomplished by performing enormous kinetic data collection and detailed mechanistic analysis on several typical fundamental organic chemical reactions. Three new methodologies for differentiating between a simple one-step and complex multi-step mechanism were developed and extensively confirmed during the application in the kinetic studies of all of the reaction discussed in this dissertation. The three methods consist of (1) half-life dependence of kapp, (2) sequential linear pseudo-first-order correlation, and (3) revised instantaneous rate constant analysis. A detailed kinetic investigation of the formal hydride transfer reaction of NADH models [N-benzyl-1,4-dihydronicotinamide (BNAH) with Nmethylacridinium (MA+) and N-methyl-9,10-dihydroacridine (MAH) with tropylium ion (Tr+)] confirmed that both these reactions take place in more than one step and involve kinetically significant reactant complex intermediates, which are noncovalentlly bound intermediates. Computations at the M06-2x/6-311++G(d,p) level provided the structure of the reactant complex intermediate. A reinvestigation of the formal hydride transfer reaction of 1-benzyl-3- cyanoquinolinium ion (BQCN+) with N-methyl-9,10-dihydroacridine (MAH) in acetonitrile (AN) confirmed that the reaction takes place in more than one step and revealed a new mechanism that had not previously been considered. It was observed that even residual oxygen under glove box conditions initiates a chain process leading to the same products. The combination reactions studied include the reaction between a carbocation and an anion as well as the reaction of trans-β-nitrostyrene with nitroethide ion. Conventional pseudo-first-order analysis as well as instantaneous rate constant analysis confirmed that the combination reactions do not follow the simple one-step mechanism. The SN2 displacement of halide ions by the 4- nitrophenoxide ion was also investigated and the kinetic data are inconsistent with the concerted single transition-state model.

Investigations of Field Performance and Physiological Effects of Metsulfuron and Metsulfuron Combinations on Field Bindweed (Convolvulus arvensis L.)Mashhadi, Hamid Rahimian 01 May 1987 (has links)
Field bindweed (Convolvulus arvensis L.) is a noxious perennial weed of many fallow and cropland fields all over the world. Present control methods are not satisfactory for field bindweed. Metsulfuron, 2[[[[(4-methoxy-6-methyl-1,3,5-triazine-2-yl) amino] carbonyl] amino] sulfonyl] benzoic acid, is a new herbicide that has been shown to have activity on bindweed especially when tank mixed with other herbicides. This study was conducted to investigate the field performance and some physiological effects of metsulfuron on field bindweed.
Neither metsulfuron alone nor metsulfuron combinations gave persistent control of field bindweed. Metsulfuron usually increased the activity of other bindweed herbicides. Herbicide application to field bindweed in the full bloom growth stage did not control the weed as well as the same treatments in the prebloom growth stages and treating regrowth the fall after tilling bindweed in full blossom. Application of metsulfuron at full bloom decreased seed weight, seed size seed viability and seedling vigor of field bindweed but did not alter seed set.
Metsulfuron at 23 g/ha and above caused unacceptable injury to barley (Hordeum vulgaris L.) and oats (Avena sativa L.). Higher rates of metsulfuron resulted in greater phytotoxicity.
Metsulfuron stopped photosynthesis of field bindweed within two weeks regardless of herbicide dosage used. Field bindweed seedlings were observed growing in the field under light intensities of 28 to 62 μmoles m-2 s-1 which was below the light compensation point obtained for greenhouse grown bindweed plants (about 65 μmoles m-2 s-1).
Higher quantities of 14C labelled metsulfuron per mg plant dry weight were recovered in the above treated leaf sections than in any other parts of bindweed plants. Metsulfuron applied as a foliage spray two days prior to administering 14C metsulfuron significantly increased absorption to the radiolabelled herbicide in field bindweed plants.

Kulturmöte i gränslandet mellan motsättningar och möjligheter : Strategier för att tillvarata kulturmötens kreativa potentialCvetković, Anita January 2008 (has links)
Encounters and relations between people with different cultural backgrounds tend to be primarily discussed in terms of exclusio, prejudice and conflict. This thesis focuses on the creative aspects of intercultural encounters. The starting point is that the parties involved sometimes succeed in avoiding the latent conflicts between cultures by acting trategically. The aim of this thesis is to increase understanding of the possibilities represented by intercultural encounters and to identiy the strategies employed by the actors who try to deal with the contrasts and dilemmas involved in encounters with other peopl with different cultural experiences, identities and methods. The empirical part of the thesis is based on four qualitative case studies that are characterised by rather positive co‐operation between the actors in the intercultural encounter, i.e. "immigrants" and the majority society in Sweden. The empirical data are based on 45 individual interviews, two focus group discussions and a number of minor observations made in the inland part of northern Sweden, where the case studies were carried out. The principal result of this research is that the actors begin to see culture as a possibility when they find themselves in a osition where they feel obliged to change their established patterns of behaviour, due to some sort of crisis situation. The strategies used by the actors to deal with culture conflicts can be divided into intra‐group strategies and inter‐group strategies. The former attempt to achieve relative homogeneity between the competing groups in the field of the intercultural encounter, while the latter illustrate how the participants deal with what they experience as differences. Four inter‐group strategies have been identified: 1) the status quo strategy, 2) the loose coupling strategy, 3) the selective strategy and 4) a culture mixing strategy. The latter three are characterised by innovative combinations that organise the existing cultural elements in a meaningful way These strategies result in new cognitive structures, whose limits maintain the balance between different cultural elements. / Möten och relationer bland människor med olika kulturell bakgrund diskuteras idag övervägande i termer av social och kulturell exkludering, fördomar och motsättningar. I denna avhandling har jag valt att fokusera på kulturmötens kreativa aspekter. Min utgångspunkt är att deltagande parter i vissa fall lyckas att kringgå kulturmötenas inneboende motsättningar och överbrygg det kulturella avståndet genom att handla strategiskt. Syftet med avhandlingen har varit att öka förståelsen av kulturmötens möjligheter och att identifiera aktörernas handlingsmönser när de försöker hantera kontraster och dilemman i möten med människor som skiljer sig i fråga om kulturella erfarenheter, identiteter och metoder. Hur handlingarna organiseras för att förmå människor att gemensamt fungera under kulturmötenas villkor, är frågan vars svar förväntas förtydliga hur den kreativa potentialen i kulturmöten kan tillvaratas. Utformning av aktuella handlingsstrategier och deras effekter analyseras i termer av motsvarande kognitiva strukturer. Dessa ställs mot varandra och analyseras i ett kognitivt sociologiskt perspektiv. Avhandlingens empiriska del grundas på fyra kvalitativa fallstudier. Bedömningsgrunder för urvalet av dessa fall har varit att det skulle röra sig om händelser eller projekt som äger rum i glesbyden och som inkluderar en någorlunda affirmativ bild av samverkan mellan aktörer från olika kulturell bakgrund. Ett av de studerade fallen har exemplifierat en icke‐affirmativ bild av samverkan för att kontrastera de övriga fallen. Empiriska data har insamlats genom totalt 45 individuella intervjuer, två fokusgruppsdiskussioner samt några mindre observationer. Avhandlingens huvudresultat är att aktörerna uppfattar kultur som en möjlighet först när behovet att förändra etablerade beteenemönster upplevs som nödvändigt på grund av krisförhållanden. I den meningen kan kris och instabilitet ses som en förutsättning för att kulturmötens kreativa möjligheter ska kunna tillvaraas. Handlingsstrategier som aktörerna använt för att hantera kulturella motsättningar kan uppdelas i inomgruppsstrategier och mellngruppsstrategier. De förstnämnda syftar till att uppnå en relativ homogenisering bland de konkurrerande grupperna inom de fält som ingår i kultumöten, medan de sistnämnda åskådliggör hur deltagarna går tillväga för att hantera uppfattade olikheter. Jag har identifierat fyra mellangruppstrategier: 1) status quo‐strategi, 2) frikopplingsstrategi, 3) selektiv strategi och 4) kulturblandningsstrategi. De tre sistnämnda kännetecknas av innovativa sammanställningar som organiserar befintliga kulturella element på ett meningsfult sätt. Effekter av dessa strategier resulterar i nya kognitiva strukturer, vars gränsdragningar bevarar en balansgång mellan olika kulturella element.
