13. A aviaÃÃo agrÃcola no Brasil: um modelo para seleÃÃo de aviÃes com o uso da programaÃÃo linear / The agricultural aviation in Brazil: a model for selection of airplanes with the use of the linear programming
The objective of this work is the optimization of the more viable model to the agricultural airplane for certain area of soybean cultivation, with possibility from decrease of costs and risks in the activity, increasing the competitiveness of the agrobusiness through the linear programming. The work presents a literature revision about the concepts of microe

14. Avaliação da osteoporose em mulheres idosas pelo DXA e pelos questionários do EVOS e de AIVD
xi The precocious recognition of the aged women how much the biggest possibility to have the illness osteoporosis is basic to diminish the impact that sequels of this disease can cause. Osteoporosis is a quiet illness what it implies in the recognition of the factors of inherent risk to each woman in the determination of strategies of improvement of the qual

15. Diversidade e sazonalidade de Anopheles sp. (Diptera : Culicidae) com Ãnfase na prevalÃncia de malÃria em Roraima / Diversity and seasonality of anopheles sp. (diptera: Culicidae) with emphasis on malaria prevalence in Roraima
Malaria remains one of the most important infectious diseases in the world. It is estimated that 400 million cases occur every year, especially in tropical and subtropical regions. In this project we have studied entomological and epidemiological aspects of transmission in the State of Roraima, in Northern Amazon, Brazil. The region presents a diversity of e

16. Temporal distribution of five bat species (Chiroptera, Phyllostomidae) from Panga Reserve, south-eastern Brazil
Data about activity patterns, hourly and monthly, on five phyllostomid bats, Glossophaga soricina (Pallas, 1766), Anoura caudifer (E. Geoffroy, 1818), Camilla perspicillata (Linnaeus, 1758), Sturnira lilium (E. Geoffroy, 1810) and Platyrrhinus lineatus (E. Geoffroyi, 1810), studied over a one year period at the Panga Ecological Reserve, Uberlandia, Minas Ger

17. Biting Indices, Host-seeking Activity and Natural Infection Rates of Anopheline Species in Boa Vista, Roraima, Brazil from 1996 to 1998
The epidemiology of the transmission of malaria parasites varies ecologically. To observe some entomological aspects of the malaria transmission in an urban environment, a longitudinal survey of anopheline fauna was performed in Boa Vista, Roraima, Brazil. A total of 7,263 anophelines was collected in human bait at 13 de Setembro and Caranã districts: Anoph

18. Influência do ciclo lunar na atividade de vôo de Coquillettidia (Rhynchotaenia) venezuelensis (Theobald) (Diptera, Culicidae) na Mata Atlântica, Serra do Marumbi, Morretes, Paraná, Brasil
From October 1995 to January 1996 a survey of the culicid species mentioned above was carried out in a restrict Atlantic Forest area, located in the Marumbi mountain (approximately 6,5 km from the town of Morretes). Shannon light trap was used during 48 nights, in the four lunar phases: full moon, first quarter, new moon and last quarter between evening and

19. Concentrations of some antibiotics in synovial fluid after oral administration, with special reference to antistaphylococcal activity.
One of 4 antibiotics with antistaphylococcal activity was given in a conventional oral dose for one day to each of 20 hospitalised patients with synovial effusion of a knee joint requiring aspiration. Serial synchronous samples of serum and synovial fluid (SF) were taken over 36 hours through indwelling cannulae. No morbidity was experienced either during or

20. Placebo controlled trial of xamoterol versus digoxin in chronic atrial fibrillation.
Thirteen patients in chronic atrial fibrillation with a normal resting heart rate but with exercise tachycardia and episodes of bradycardia were randomised to treatment periods of two weeks on xamoterol (200 mg twice daily), low dose digoxin, or placebo, in a blind crossover study. The results (mean SEM) of symptom scores, a treadmill exercise test, and 24 h

21. Quantifying the risk of sports injury: a systematic review of activity‐specific rates for children under 16 years of age
Injuries caused by sports and other forms of physical activity in young children constitute a significant public health burden. It is important to quantify this risk to ensure that the benefits of sport participation are not outweighed by the potential harms. This review summarises the literature reporting exposure‐based injury rates for various forms of p

22. Circadian variation in biochemical assessments used to monitor rheumatoid arthritis.
Circadian variation has been demonstrated in several clinical parameters used to assess disease activity in rheumatoid arthritis, but circadian variation in modern laboratory assessments has not been studied in depth. We therefore made 2-hourly measurements of plasma viscosity, C-reactive protein, total serum sulphydryl, and serum histidine on samples obtain

23. A comparison of work-sampling and time-and-motion techniques for studies in health services research.
OBJECTIVE. This study compares results and illustrates trade-offs between work-sampling and time-and-motion methodologies. DATA SOURCES. Data are from time-and-motion measurements of a sample of medical residents in two large urban hospitals. STUDY DESIGN. The study contrasts the precision of work-sampling and time-and-motion techniques using data actually c

24. Time Course of Purine Nucleoside Phosphorylase Occurrence in Sporulation of Bacillus cereus
Purine nucleoside phosphorylase (EC 2.4.2.1) from Bacillus cereus T was examined at hourly intervals during growth and sporulation. The enzyme has maximal activity in extracts prepared from cells during stages I and II. The activity during exponential growth is only 6.6% of the maximum and that in free spores is only 3.3%. Conservation of the purine nucleosi
