Controle da lagarta-da-soja com aplicações de seu vírus de poliedrose nuclear por vias aérea e terrestre

De 1983 a 1988 foram conduzidos, na região de Dourados, MS, seis experimentos e três campos-piloto, objetivando controlar a lagarta Anticarsia gemmatalis Hübner, 1818, com aplicações aérea e terrestre de seu vírus de poliedrose nuclear (VPN Ag). Cem lagartas equivalentes (LE) de VPN Ag associadas a óleo de soja, melaço de cana-de-açúcar e água, foram aplicadas com avião agrícola equipado com Micronair. Os preparados oleosos (5,5 e 5 L ha-1) e com melaço (10 L ha-1) controlaram 75-89% e 79-96% das lagartas, respectivamente. A suspensão aquosa de 3 L ha-1 foi ineficaz, porém as de 15, 20 e 25 L ha-1 controlaram de 81% a 90% das lagartas. Cinqüenta LE, aplicadas com avião agrícola (3 L ha-1) ou atomizador (15 L ha-1), foram ineficientes. Aplicações da mesma dose com pulverizador de barra (134 e 150 L ha-1) proporcionaram controle de 87% e 90%, respectivamente, e com avião (15, 20 e 25 L ha-1), entre 93% e 98%. Aplicações aéreas de 50 LE com óleo de soja (5 L ha-1) ou melaço (10 L ha-1) foram eficientes (86-88% e 99%, respectivamente). Aplicações aéreas de suspensões aquosas e formulado oleoso, em campos-piloto, confirmaram os resultados experimentais.

Biomassa aérea e produção primária do estrato herbáceo em campo de Elyonurus muticus submetido à queima anual, no Pantanal

O trabalho foi conduzido no Pantanal, em fitofisionomia de campo a savana, regionalmente denominada de caronal, pela dominância de Elyonurus muticus. Os objetivos foram avaliar o efeito da queima anual de caronal sobre a biomassa aérea acumulada, produção primária líquida da parte aérea (PPLA) do estrato herbáceo e cobertura do solo. Foram coletados dados mensais de biomassa aérea acumulada durante dois anos, em uma área com queima em set./95 e ago./96, e outra sem queima. A PPLA foi estimada através das diferenças de biomassa aérea viva coletada mensalmente. A queima reduziu a biomassa aérea acumulada em aproximadamente 36% no primeiro ano e 50% no segundo. Houve uma tendência de redução de biomassa acumulada com a repetição da queima. A PPLA do estrato herbáceo nas áreas sem queima e com queima foi 3.850 kg/ha e 4.980 kg/ha no primeiro ano, e 5.090 kg/ha e 2.880 kg/ha no segundo, respectivamente. A cobertura do solo 30 dias após a queima foi de aproximadamente 30%, e somente quatro a seis meses depois foi restabelecido o porcentual da área sem queima

Composição e dinâmica da biomassa aérea após a queima em savana gramíneo-lenhosa no Pantanal

O objetivo deste estudo foi avaliar a composição e dinâmica da biomassa aérea após a queima de uma savana gramíneo-lenhosa no Pantanal. Foram coletados dados mensais de freqüência de espécies, biomassa aérea e cobertura do solo durante 11 meses em uma área com queima (CQ) e outra sem queima (SQ), ambas sem pastejo. A queima reduziu a freqüência das gramíneas predominantes e condicionou aumento no número de espécies dicotiledôneas e ciperáceas. A produção de biomassa aérea total foi inferior na área com queima, embora a tendência de incremento tenha sido semelhante nas duas áreas. A produção de biomassa morta foi muito afetada pela queima, cuja produção, 11 meses após, representou aproximadamente 25% da obtida na área sem queima. A cobertura do solo foi inferior na área com queima e somente no quarto mês assemelhou-se à área sem queima.

rKv1.2 overexpression in the central medial thalamic area decreases caffeine-induced arousal.

The voltage-gated potassium channel Kv1.2 belongs to the shaker-related family and has recently been implicated in the control of sleep profile on the basis of clinical and experimental evidence in rodents. To further investigate whether increasing Kv1.2 activity would promote sleep occurrence in rats, we developed an adeno-associated viral vector that induces overexpression of rat Kv1.2 protein. The viral vector was first evaluated in vitro for its ability to overexpress rat Kv1.2 protein and to produce functional currents in infected U2OS cells. Next, the adeno-associated Kv1.2 vector was injected stereotaxically into the central medial thalamic area of rats and overexpression of Kv1.2 was showed by in situ hybridization, ex vivo electrophysiology and immunohistochemistry. Finally, the functional effect of Kv1.2 overexpression on sleep facilitation was investigated using telemetry system under normal conditions and following administration of the arousing agent caffeine, during the light phase. While no differences in sleep profile were observed between the control and the treated animals under normal conditions, a decrease in the pro-arousal effect of caffeine was seen only in the animals injected with the adeno-associated virus-Kv1.2 vector. Overall, our data further support a role of the Kv1.2 channel in the control of sleep profile, particularly under conditions of sleep disturbance.

The european higher education area at work: Lights and shadows defining continuous assessment

The aim of this paper is to analyse how learning assessment, particularly the Continuous Assessment system, has been defined in the Public Administration and Management Diploma Course of the University of Barcelona (Spain). This course was a pioneering experiment at this university in implementing the guidelines of the European Higher Education Area (EHEA), and thus represents a good case study for verifying whether one of the cornerstones of the EHEA has been accomplished with success. Using data obtained from the Teaching Plans elaborated by the lecturers of each subject, we are able to establish that the CA system has been progressively accepted to such an extent that it is now the assessment formula used by practically all of the lecturers, conforming in this way to the protocols laid down by the Faculty of Law in which this diploma course is taught. Nevertheless, we find that high dispersion exists in how Continuous Assessment is actually defined. Indeed, it seems that there is no unified view of how Continuous Assessment should be performed. This dispersion, however, seems to diminish over time and raises some questions about the advisability of agreement on criteria, considering the potential which CA has as a pedagogical tool. Moreover, we find that the Unique Assessment system, which students may also apply for, is an option chosen only by a minority, with lecturers usually defining it as merely a theoretical and/or practical test, of little innovation in relation to traditional tests.

Examination of Existing Highway Maintenance Garage Locations in Tama and Blairstown Study Area, 1983

An optimum allocation model has been utilized to examine the existing allocation of highway segments to maintenance garages in the Tama and Blairstown study area. The model has also been used to evaluate the financial impact of closing the highway maintenance garages at Tama and Blairstown and building a new garage at the junction of U.S. 30 and Iowa 21. The examination of the study area shows that only 13 of 91 highway segments were reallocated under optimum procedures at an annual operational savings of approximately $13,200. The study concludes there would be an annual operational savings of approximately $48,200 if the garages at Tama and Blairstown were closed and a new garage was built at the junction of U.S. 30 and Iowa 21.

Efeito da freqüência e altura de poda na produtividade de raízes e parte aérea em mandioca

O objetivo do presente trabalho foi avaliar o efeito da altura e freqüência de poda, sobre a produtividade de parte aérea e de raízes em cinco cultivares de mandioca. Foram avaliadas duas alturas (0,50 m e 1,00 m) e três freqüências de poda (aos 6, 12 e 18 meses, aos 12 e 18 meses e aos 18 meses), envolvendo as cultivares Paxiubão, Pretinha, Paxiúba II, Metro III, e Pirarucu. A produção de matéria verde e a porcentagem de folhas foram inversamente proporcionais à idade das plantas. Com exceção da cultivar Paxiubão, os rendimentos de raízes foram reduzidos com o aumento da freqüência de podas. O rendimento de raízes foi reduzido tanto pela altura como pela freqüência de poda, enquanto o rendimento de matéria verde foi influenciado pela freqüência de poda. A altura e a freqüência de poda reduziram o teor de matéria seca de raízes e elevaram o índice de podridão de raízes. A freqüência de poda reduziu o teor de ácido cianídrico nas raízes. Para o aproveitamento simultâneo da parte aérea e raízes recomenda-se a cultivar Paxiubão com poda aos 6 e 12 meses.

Nutritional deficiencies after Roux-en-Y gastric bypass for morbid obesity often cannot be prevented by standard multivitamin supplementation

BACKGROUND: Despite the increasing use of Roux-en-Y gastric bypass (RYGBP) in the treatment of morbid obesity, data about postoperative nutritional deficiencies and their treatment remain scarce. OBJECTIVE: The aim of this study was to evaluate the efficacy of a standard multivitamin preparation in the prevention and treatment of nutritional deficiencies in obese patients after RYGBP. DESIGN: This was a retrospective study of 2 y of follow-up of obese patients after RYGBP surgery. Between the first and the sixth postoperative months, a standardized multivitamin preparation was prescribed for all patients. Specific requirements for additional substitutive treatments were systematically assessed by a biologic workup at 3, 6, 9, 12, 18, and 24 mo. RESULTS: A total of 137 morbidly obese patients (110 women and 27 men) were included. The mean (+/-SD) age at the time of surgery was 39.9 +/- 10.0 y, and the body mass index (in kg/m(2)) was 46.7 +/- 6.5. Three months after RYGBP, 34% of these patients required at least one specific supplement in addition to the multivitamin preparation. At 6 and 24 mo, this proportion increased to 59% and 98%, respectively. Two years after RYGBP, a mean amount of 2.9 +/- 1.4 specific supplements had been prescribed for each patient, including vitamin B-12, iron, calcium + vitamin D, and folic acid. At that time, the mean monthly cost of the substitutive treatment was $34.83. CONCLUSION: Nutritional deficiencies are very common after RYGBP and occur despite supplementation with the standard multivitamin preparation. Therefore, careful postoperative follow-up is indicated to detect and treat those deficiencies.
