OBJECTIVE: To assess the incidence of problems requiring reprogramming of atrioventricular pacemakers in a long-term follow-up, and also the causes for this procedure. METHODS: During the period from May '98 to December '99, 657 patients were retrospectively studied, An actuarial curve for the event reprogramming of the stimulation mode was drawn. RESULTS: The follow-up period ranged from 12 to 178 months (mean = 81 months). Eighty-two (12.4%) patients underwent reprogramming of the stimulation mode as follows: 63 (9.5%) changed to VVI,(R/C); 10 (1.5%) changed to DVI,C; 6 (0.9%) changed to VDD,C; and 3 (0.5%) changed to DOO. The causes for the reprogramming were as follows: arrhythmia conducted by the pacemaker in 39 (37.6%) patients; loss of atrial sensitivity or capture, or both, in 39 (38.6%) patients; and microfracture of atrial electrode in 5 (4.9%) patients. The stimulation mode reprogramming free probability after 15 years was 58%. CONCLUSION: In a long-term follow-up, the atrioventricular pacemaker provided a low incidence of complications, a high probability of permanence in the DDD,C mode, and the most common cause of reprogramming was arrhythmia conducted by the pacemaker.

We have developed the computer programme NUTRISOL, a nutritional programme destined to analysis of dietary intake by means of the food transformation to nutrient. It has been performed under Windows operative system, using Visual Basic 6.0. It is presented in a CD-Rom. We have used the Spanish CSIC Food Composition Table and domestic food measures commonly used in Spain which could be modified and updated. Diverse kind of diets and reference anthropometric data are also presented. The results may be treated using various statistical programmes. The programme contains three modules: 1) Nutritional epidemiology, which allows to create or open a data base, sample management, analyse food intake, consultation of nutrient content and exportation of data to statistical programmes. 2) Analyses of diets and recipes, creation or modification of new ones. 3) To ask different diets for prevalent pathologies. Independent tools for modifying the original tables, calculate energetic needs, recommend nutrient intake and anthropometric indexes are also offered. In conclusion, NUTRISOL Programme is an application which runs in PC computers with minimal equipment in a friendly interface, of easy use, freeware, which may be adapted to each country, and has demonstrated its usefulness and reliability in different epidemiologic studies. Furthermore, it may become an efficient instrument for clinical nutrition and health promotion.

Geographic information systems (GIS) and artificial intelligence (AI) techniques were used to develop an intelligent snow removal asset management system (SRAMS). The system has been evaluated through a case study examining snow removal from the roads in Black Hawk County, Iowa, for which the Iowa Department of Transportation (Iowa DOT) is responsible. The SRAMS is comprised of an expert system that contains the logical rules and expertise of the Iowa DOTs snow removal experts in Black Hawk County, and a geographic information system to access and manage road data. The system is implemented on a mid-range PC by integrating MapObjects 2.1 (a GIS package), Visual Rule Studio 2.2 (an AI shell), and Visual Basic 6.0 (a programming tool). The system could efficiently be used to generate prioritized snowplowing routes in visual format, to optimize the allocation of assets for plowing, and to track materials (e.g., salt and sand). A test of the system reveals an improvement in snowplowing time by 1.9 percent for moderate snowfall and 9.7 percent for snowstorm conditions over the current manual system.

O presente trabalho estudou os compostos bioativos (cidos clorognicos, trigonelina, cafena, fenis totais e proantocianidinas), grupos hidroxila cidos e atividade antioxidante de um caf arbica proveniente do Cerrado Mineiro e de seu PVA (gros pretos, verdes e ardidos). As amostras foram preparadas nas torras clara (180 10 C; 6,0 1,0 minutos), mdia (180 10 C; 8,0 1,0 minutos) e escura (180 10 C; 10,0 1,0 minutos). Considerando-se a mdia das trs torras do caf e do PVA, a diferena observada no teor de todos os constituintes acima no foi significativa (p > 0,05), exceto com o teor de grupos hidroxila cidos que foi ligeiramente superior no PVA e cafena calculada pelo mtodo semiquantitativo que foi superior no caf. Portanto, dentre esses constituintes, os compostos com grupos cidos seriam os nicos que poderiam contribuir para explicar a grande diferena de sabor existente entre o caf de gros sadios e o de PVA. Tanto o caf como o PVA apresentaram atividade seqestradora do radical DPPH. nas trs torras, sendo a atividade do caf sempre superior. Analisando-se as variaes dos teores de cafena, fenis totais, proantocianidinas, grupos hidroxila cidos, trigonelina e cidos clorognicos, no foi possvel explicar a atividade antioxidante superior apresentada pelo caf da torra mdia (CE50 de 2,3 mg.mg-1 de DPPH.).

Este estudo teve por objetivo estimar, pelo modelo CENTURY, a alterao no estoque de carbono orgnico (CO) de solos do Planalto do Rio Grande do Sul durante o perodo de expanso da agricultura e o potencial de recuperao do estoque de CO atravs de diferentes sistemas de manejo. Foram utilizados solos de cinco Unidades de Mapeamento (UM), sob vegetao original de campo e floresta: LATOSSOLO VERMELHO Distfico tpico (UM Cruz Alta e Passo Fundo), LATOSSOLO VERMELHO Distrofrrico tpico (UM Santo ngelo e Erechim) LATOSSOLO BRUNO Alumnico cmbico e (UM Vacaria). Avaliou-se a expanso da agricultura nas UM, a variao no contedo de CO dos solos por decomposio microbiana e eroso e a emisso ou seqestro de CO2 em cenrios de manejo com diferentes adies de C, mtodos de preparo do solo e perdas de solo por eroso. Durante o perodo de expanso da agricultura (1900-1980), o uso de sistemas de cultura com baixa adio de C, pousio, queima de resduos e preparo convencional do solo, ocasionou redues estimadas de 31 a 45% no estoque original de CO dos solos. Com a melhoria nos eventos de manejo a partir de 1981, houve a recuperao parcial no estoque de CO. Considerando o balano de CO e CO2 para a regio em estudo (52506 km2), o cenrio de manejo 1 (PC trigo/soja com queima) apresentou perda total estimada de 159517,0x103 Mg de CO e emisso de 299562,10x103 Mg de CO2 atmosfera. Nos demais cenrios, foram estimados incrementos de CO em relao ao cenrio 1, atingindo, em 2050, valores correspondentes a 68,5% (cenrio 2 - PR trigo/soja sem queima), 92,7% (cenrio 3 - PD trigo/soja, aveia/soja, aveia/milho) e 98,1% (cenrio 4 - PD trigo/soja, aveia/milho) do estoque original de CO. Devido a alta adio anual de C (6,0 Mg ha-1) e uso do plantio direto, o cenrio 4 apresentou seqestro lquido de 52173,32x103 Mg de CO2.
