An intra-household approach to the welfare costs of inflation (Revised Version, Forthcoming 2006, Estudos Econômicos)

The literature on the welfare costs of ináation universally assumes that the many-person household can be treated as a single economic agent. This paper explores what the heterogeneity of the agents in a household might imply for such welfare analyses. First, we show that allowing for a one-person or for a many-person transacting technology impacts the money demand function and, therefore, the welfare costs of ináation. Second, more importantly, we derive su¢ cient conditions under which welfare assessments which depart directly from the knowledge of the money demand function (as in Lucas (2000)) are robust (invariant) under the number of persons considered in the household. Third, we show that Baileyís (1956) partial-equilibrium measure of the welfare costs of ináation can be obtained as a Örst-order approximation of the general-equilibrium welfare measure derived in this paper using a many-person transacting technology.

Aplicações das Integrais

Este capítulo começa com integração de funções racionais, ou seja, funções da forma f(x)/g(x) e a resolução de um exemplo passo a passo. O primeiro exemplo mostra que se o grau de f(x) for maior que o grau de g(x), então a integral da função racional f(x)/g(x) se transforma numa integral de simples resolução, através da divisão de polinômios. Portanto a unidade mostra que é preciso apenas estudar integrais de funções racionais próprias, isto é, funções racionais em que o grau do numerador é menor que o grau do denominador. Isto é desenvolvido através da decomposição de frações racionais em frações parciais. Na sequência é apresentado passo a passo como fazer tal decomposição em três casos distintos. E no último tópico são detalhadas algumas aplicações das integrais definidas: área de uma região plana; média ou valor médio de uma função; volume de um sólido; área de uma superfície de revolução.

Bacterial translocation in rats nonfunctioning diverted distal colon

To investigate whether the alterations of the diverted colon segment mucosa, evidenced in fecal colitis, would be able to alter Bacterial Translocation (BT). Methods: Sixty-two Wistar male rats ranging from 220 to 320 grams of weight, were divided in two groups: A (Colostomy) and B (Control), with 31 animals each one. In group A, all animals underwent end colostomy, one stoma, in ascending colon; and in the 70th POD was injected in five rats, by rectal route – diverted segment - 2ml of a 0.9% saline solution in animals (A1 subgroup); in eight it was inoculated, by rectal route, 2ml of a solution containing Escherichia coli ATCC 25922 (American Type Culture Collection), in a concentration of 108 Colony Forming Unit for milliliters (CFU/ml) - A2 Subgroup; in ten animals the same solution of E. coli was inoculated, in a concentration of 1011 CFU/ml (A3 Subgroup); and in eight it was collected part of the mucus found in the diverted distal colonic segment for neutral sugars and total proteins dosage (A4 subgroup). The animals from the group B underwent the same procedures of group A, but with differences in the colostomy confection. In rats from subgroups A1, A2, A3, B1, B2, and B3 2ml of blood were aspirated from the heart, and fragments from mesenteric lymphatic nodule, liver, spleen, lung and kidney taken for microbiological analysis, after their death. This analysis consisted of evidencing the presence of E. coli ATCC 25922 CFU. Mann-Whitney and ANOVA Tests were applied as analytic techniques for association of variables. Results: The occurrence of BT was evidenced only in those animals in which inoculated concentration of E. coli ATCC 25922, reached levels of 1011CFU/ml, i.e. in Subgroups A3 and B3, although, being significantly greater (80%) in those animals without colostomy (subgroup B3) when compared to the ones with colostomy (20%) from the subgroup A3 (P <0.05). Lung, liver and mesenteric lymphatic nodules were the tissues with larger percentile of bacterial recovery, so much in subgroup A3, as in B3. Blood culture was considered positive in 60% of the animals from subgroup B3 and in 10% of those from subgroup A3 (p <0.05). There was greater concentration of neutral sugars, in subgroup A4 - mean 27.3mg/ml -, than in subgroup B4 - mean 8.4mg/ml - (P <0.05). Conclusion: The modifications in the architecture of intestinal mucosa in colitis following fecal diversion can cause alterations in the intestinal barrier, but it does not necessarily lead to an increased frequency of BT

Estudo do processo de combustão in-situ em reservatórios maduros de óleos médios e leves (high pressure air injection)

Nearly 3 x 1011 m3 of medium and light oils will remain in reservoirs worldwide after conventional recovery methods have been exhausted and much of this volume would be recovered by Enhanced Oil Recovery (EOR) methods. The in-situ combustion (ISC) is an EOR method in which an oxygen-containing gas is injected into a reservoir where it reacts with the crude oil to create a high-temperature combustion front that is propagated through the reservoir. The High Pressure Air Injection (HPAI) method is a particular denomination of the air injection process applied in light oil reservoirs, for which the combustion reactions are dominant between 150 and 300°C and the generation of flue gas is the main factor to the oil displacement. A simulation model of a homogeneous reservoir was built to study, which was initially undergone to primary production, for 3 years, next by a waterflooding process for 21 more years. At this point, with the mature condition established into the reservoir, three variations of this model were selected, according to the recovery factors (RF) reached, for study the in-situ combustion (HPAI) technique. Next to this, a sensitivity analysis on the RF of characteristic operational parameters of the method was carried out: air injection rate per well, oxygen concentration into the injected gas, patterns of air injection and wells perforations configuration. This analysis, for 10 more years of production time, was performed with assistance of the central composite design. The reservoir behavior and the impacts of chemical reactions parameters and of reservoir particularities on the RF were also evaluated. An economic analysis and a study to maximize the RF of the process were also carried out. The simulation runs were performed in the simulator of thermal processes in reservoirs STARS (Steam, Thermal, and Advanced Processes Reservoir Simulator) from CMG (Computer Modelling Group). The results showed the incremental RF were small and the net present value (NPV) is affected by high initial investments to compress the air. It was noticed that the adoption of high oxygen concentration into the injected gas and of the five spot pattern tends to improve the RF, and the wells perforations configuration has more influence with the increase of the oil thickness. Simulated cases relating to the reservoir particularities showed that smaller residual oil saturations to gas lead to greater RF and the presence of heterogeneities results in important variations on the RF and on the production curves

EFEITOS da SIMULAÇÃO DE DERIVA DE CLOMAZONE em PLANTAS DE LARANJEIRA 'HAMLIN'

Em trabalho realizado em 1998, no município de Taiúva-SP, objetivou-se avaliar o efeito da simulação da deriva de doses crescentes, até atingir a recomendada comercialmente, de clomazone, em duas formulações, e de clomazone em mistura com ametryne, em laranjeira-'Hamlin' com frutos com 2 a 4 cm de diâmetro. O delineamento experimental utilizado foi o de blocos casualizados, com 15 tratamentos, em 3 repetições. As avaliações basearam-se em possíveis alterações morfofisiológicas das plantas, com determinações do teor de clorofila total nas folhas, porcentagem de abortamento de frutos, além de análise tecnológica dos frutos. Concluiu-se que a dose comercial de clomazone isolado e em mistura com ametryne a 50 e 100% da dose resultou na formação de manchas cloróticas e/ou necróticas na casca do fruto e causou mortalidade de ramos que se encontravam em crescimento vegetativo, não acarretando qualquer alteração qualitativa do suco.

Study of caffeine urine and saliva of horses subjected to urinary acidification

The study of caffeine in racing horses has been of growing concern in veterinary sports medicine since the Association of Racing Commissioners International (ARCI) stated that it has no valid therapeutic use in racehorses. We examined the kinetic alterations in the urinary excretion and salivary secretion of caffeine in seven horses subjected to urinary acidification using ascorbic acid because this procedure can simulate the acidosis that follows anaerobic exercise. They participated in two treatment groups: the control group (SG) received 500 ml of saline and then 2.0 mg kg(-1) caffeine i.v. 30 min later; and the acidified group (AG) was subjected to urinary acidification with ascorbic acid at a dose of 0.5 g kg(-1) i.v. and then 2.0. mg kg(-1) caffeine i.v. 30 min later. Samples were collected 30 min before caffeine administration, immediately before caffeine administration (time zero) and at 0.25, 0.5, 1, 2, 4, 6, 8, 12, 24, 48 and 72 h afterwards. The samples were assayed by gas chromatography. The mean urinary pH for SG was 8.2, but for AG it was as low as 5.9 at 4 h, extending acidosis for up to 8 h. The kinetic curves for the two groups were similar for urinary excretion and salivary secretion. Differences occurred only in peak excretion and peak secretion in SG obtained at 1 h and 30 min, respectively, and in AG at 2 h and 1 h, respectively. This could be explained, in part, to the diuresis in AG compared with SG, resulting in less concentrated urine in the former group. The large difference between the pK(a) of caffeine and the pH of the medium may be responsible for the similar pharmacokinetics observed for the two groups. Copyright (C) 2004 John Wiley Sons, Ltd.

Emergência e crescimento inicial de plântulas de Archontophoenix cunninghamiana H. Wendl. & Drude provenientes de sementes de diferentes plantas matrizes

A diversidade genética é um fator fundamental nos programas de melhoramento e seleção de plantas, dessa forma, o objetivo no trabalho foi avaliar genótipos de Archontophoenix cunninghamiana quanto à emergência e crescimento inicial das plântulas, no sentido de orientar a seleção de plantas matrizes. Os frutos maduros foram colhidos em dez plantas matrizes em Monte Alegre do Sul - SP, nos quais se avaliaram o peso e as dimensões e, nas sementes, também o peso e as dimensões, além do teor de água, emergência, índice de velocidade de emergência, diâmetro e comprimento da parte aérea e massa seca de plântulas. O delineamento utilizado foi o inteiramente casualizado e a comparação entre médias foi realizada pelo teste de Tukey (P<0,05). Entre as sementes das matrizes, há diferenças nas características físicas e fisiológicas, o que possibilita a identificação e seleção de matrizes produtoras de sementes de qualidade superior.

Materiais corretivos e nitrogênio na nutrição e na produção de matéria seca de cana-de-açúcar cultivada em vaso

Silicon is a beneficial element that can increase the yield of sugarcane, especially when associated with nitrogen. The aim of this study was to evaluate the effects of silicate slag as a source of Si and its interaction with soil N on nutrition and dry matter production of sugar cane. The treatments consisted of two sources of correctives (limestone and silicate slag) in three doses (one half, once and twice the dose shown to increase V to 60%), two N rates (300 e 600mg.dm(-3)) administered as urea, a control (without corrective and without N), arranged in a completely randomized factorial design 2x3x2+1, with four replicates. Each experimental unit was constituted by a 40dm(3) pot filled with an Oxisol (V= 10% and Si= 10.3mg.dm(-3)), and 4 seedlings (SP79-1011). The nutritional status (Si and N) was evaluated 10 months after planting the sugarcane, as well as the Si content of the soil and shoot dry matter The application of silicate slag increased the content of available Si in soil and the plant. The application of corrective materials improved the nutrition and dry matter production of sugarcane. Nitrogen fertilization was not significant for dry matter production of the sugarcane-plant, regardless of the source of corrective material.
