1. Seed reserves reduction rate and reserves mobilization to the seedling explain the vigour of maize seeds
Resumo: Compreender como a dinâmica de reserva ocorre durante a germinação e formação de plântulas é determinante para avanços na tecnologia de sementes. Objetivou-se com este trabalho verificar qual temperatura de envelhecimento acelerado é mais eficaz para separar níveis de vigor de sementes de milho e avaliar a dinâmica de reservas durante o pr

2. Herbage utilisation efficiency of continuously stocked marandu palisade grass subjected to nitrogen fertilisation
Nitrogen fertiliser accelerates plant growth and increases herbage utilisation efficiency in continuously stocked temperate grass swards, indicating greater herbage production and harvest efficiency. There is no similar evidence, however, for tropical pastures. In this study we evaluated the morphogenetic responses, the patterns of defoliation and the effici

3. Diauxic growth of Geotrichum candidum and Penicillium camembertii on amino acids and glucose
The purpose of this work was to examine physiological differences between the yeast Geotrichum candidum and the mould Penicillium camembertii, organisms involved in the industrial process of cheese ripening. Three groups of amino acids had previously been characterized, based on their carbon assimilation and dissimilation by the two fungal species. For both

4. Eficiencia do uso de nitrogenio para producao de grao e proteina por cultivares de arroz.
Foi feito um experimento em casa de vegetacao, para avaliar a eficiencia do uso de nitrogenio (EUN) para producao de grao (PG) e de proteina bruta (PB) em dezenove cultivares de arroz. Quinze cultivares tradicionais do Estado do Maranhao, separadas por alto e baixo teor de PB, e quatro cultivares IAC melhoradas, foram cultivadas em vasos com solo, com dois n

5. Residual feed intake in beef cattle
Providing feed is a major input cost in beef production, hence improvements in the efficiency of feed utilisation will reduce the cost of production. Residual feed intake (RFI) is a measure of feed efficiency, and is defined as the difference between an animal's actual feed intake and its expected feed intake based on its size and growth. It is independent o

6. Assessment of different revolving time combinations on coffee grains drying using a fixed-bed dryer / AvaliaÃÃo de diferentes combinaÃÃes de tempo de revolvimento, em secador de camada fixa para cafÃ
This assignment aimed to value the energetic efficiency on coffee drying (Coffea Arabica, L.), with different combinations of time revolvment on a fix layer dryer. The experiment was developed on July, 2004 in Jesuitas city, ParanÃ. The dryer was compound of: a drying chamber with a capacity to 4,5 m3 of grains, chamber plenum with volum of 2,9 m3, fan with

7. A method for deriving performance indicators for product development processes.
Performance indicators are largely used in many applications related to support decision-making activities. In the context of product development, performance indicators are used to monitor the product development process effectiveness and efficiency as well the consecution of product attributes (mainly: performance, cost and quality). Although the widesprea

8. On the measurement of capacity utilisation and coast efficiency: a non-parametric approach at firm level
In this paper we evaluate the inefficiency generated by an inadequate structure of the fixed inputs and by the difficulty to adjust them in the short-run in a sample of Romanian firms in the chemical industry over the period 1996-1997. We use Data Envelopment Analysis (DEA) and apply this methodology in an innovative setting using a cost analysis instead of

9. Monitoring and evaluating cataract intervention in India.
AIM: To identify indicators to monitor and evaluate the cataract intervention programme in India. METHODS: Available data on blindness due to cataract, demography, staffing levels, and infrastructure available under the programme were reviewed. Four key elements of the programme were identified: the magnitude of blindness due to cataract and the need for sur

10. RNA polymerase induces DNA bending at yeast mitochondrial promoters.
Yeast mitochondrial RNA polymerase can bind specifically to promoter-containing DNA fragments in vitro as detected by DNAse I or methidiumpropyl-EDTA. Fe(II) protection assays and gel retardation experiments. Retardation of RNA polymerase-DNA complexes was most pronounced when the promoter was located in the middle of a DNA fragment and was diminished when R

11. Synthetic donor and acceptor splice sites function in an RNA polymerase B (II) transcription unit.
We have synthesised a 32-bp oligonucleotide containing sequences conforming to the consensus sequences for donor and acceptor splice sites. The oligonucleotide has been inserted into an RNA polymerase B (II) transcription unit and the resulting recombinant used to study the splicing mechanism. Our findings are as follows: (i) the synthetic sites function whe

12. Effects of propranolol on myocardial oxygen consumption, substrate extraction, and haemodynamics in hypertrophic obstructive cardiomyopathy.
Myocardial substrate extraction, coronary sinus flow, cardiac output, and left ventricular pressure were measured at increasing pacing rates before and after propranolol (0.2 mg/kg) in 13 patients with hypertrophic obstructive cardiomyopathy (HOCM) during diagnostic cardiac catheterisation. At the lowest pacing rate myocardial oxygen consumption varied consi
