13. Construction and the validation tests of an electronic device able to measure the half value layer in diagnostic X-ray beams / Construção de um dispositivo eletronico para determinação de camada semi-condutora em feixe de raios-x diagnostico
This work describes the construction and the validation tests of an electronic device able to measure the half value layer in diagnostic X-ray beams. The device utilizes a transducer assembled with three sensors using the photoluminescence of the organic scintillator anthracene. The light signal, proportional to the incident radiation, reaches three photo re

14. PROPOSTA DE ATUALIZAÇÃO AUTOMÁTICA DOS SISTEMAS DE DETECÇÃO DE INTRUSÃO POR MEIO DE WEB SERVICES / PROPOSAL OF AUTOMATIC UPDATE OF THE DETECTION SYSTEMS OF INTRUSION BY MEANS OF WEB SERVICES
A segurança das redes de computadores é imprescindível para seus administradores. Os Sistemas de Detecção de Intrusão (SDIs) podem torná-las mais seguras, entretanto é imperativo que esses sistemas estejam em constante atualização para desempenhar sua função de forma satisfatória. Esta dissertação propõe um modelo de compartilhamento de infor

15. Sward structure, light interception and herbage acummulation of marandu grass swards submitted to grazing intensities by continuous stocking regimes. / Estrutura do dossel, interceptação luminosa e acúmulo de forragem em pastos de Capim-Marandu submetidos a alturas de pastejo por meio de lotação contínua.
In a pastoral ecossystem the interception of incident radiation is the first step of a sequence of events that results in herbage production. Several are the factors interfering on the light interception process including sward leaf area index, structure and architecture. The objective of this experiment was to study sward struture, light interception and he

16. METROLOGICAL EVALUATION OF OPTICAL EMITTERS AND DETECTORS APPLIED TO THE CHARACTERIZATION OF ATMOSPHERIC PARTICULATES POLLUTANTS / AVALIAÇÃO METROLÓGICA DE EMISSORES E DETECTORES ÓPTICOS APLICADOS À CARACTERIZAÇÃO DE POLUENTES PARTICULADOS ATMOSFÉRICOS
The atmospheric pollution is a latent world-wide problem, and it is harmful to the health, visibility and climate. For these factors, several studies and researches have been developed to characterize the chemical composition of the pollutants, concentration, size of particles, etc, with the objective of constructing adjusted instruments for the control of t

17. Soybean canopy [Glycine max (L.), Merril photosynthetic pigments estimation by measns of spectral reflectance / Utilização da reflectância espectral para a estimativa de pigmentos fotossintéticos em dosséis de soja [Gycine Max (.L), Merril]
Photosynthetic pigments are essential for plant development, because they are responsible for the incident solar energy absorption used in photosynthesis. Individually quantifying these pigments in great extensions of agricultural crops has been made possible by hyperspectral remote sensing development and these information can be used to produce a more accu

19. Espectroscopia optica em super-redes de GaAs com dopagem delta de Si
We performed the GaAs Si delta doped superlattices optical characterization, using spectroscopic techniques as photoluminescence, photoluminescence sxcitation, time resolved photoluminescence, Raman scattering and time resolved photorefletance. Their electronic structure is such that the electron gas is confined in minibands along the growth direction and pr

20. Avaliação do ponto efetivo de medida em camaras de ionização cilindricas usadas em feixes de eletrons com energias entre 6 e 20 MeV
When ionization chambers are used. in high energy electrons beams, a disturbance of the electron flux in medium is introduced. As observed in many experiments the response should be correlated to the electron flux at the effective point of measurement which is generally displaced from the geometrical center of the chamber. The radial displacement was determi

21. The World Trade Center Attack: Helping the helpers: the role of critical incident stress management
Healthcare and prehospital workers involved in disaster response are susceptible to a variety of stress-related psychological and physical sequelae. Critical incident stress management, of which critical incident stress debriefing is a component, can mitigate the response to these stressors. Critical incident stress debriefing is a peer-driven, therapist-gui

22. Clinical complaints: a means of improving quality of care.
OBJECTIVES--To establish the reasons for clinical complaints, complainants' feelings about the original incident, and their motivation in complaining. DESIGN--Postal questionnaire survey. SETTING--24 hospitals in North West Thames region. SUBJECTS--1007 complainants who had written to 20 hospitals between 1 January 1992 and 30 June 1993 about a complaint inv

23. Time Course of Photosynthetic Response to Changes in Incident Light Energy 1
The response of whole leaf photosynthetic rate in Fragaria virginiana to sudden changes in photosynthetically active radiation (PAR) is described. Two components of the response, consisting of a time lag and time constant, are estimated under varying PAR changes for plants grown under two different light regimes. Both the time lag and time constant are found

24. Photoinduced Seed Germination of Oenothera biennis L: II. Analysis of the Photoinduction Period
The photoinduction period of Oenothera biennis L. seed germination was analyzed by varying the photoinduction temperature and by substituting red light pulses for continuous red light. At 24°C, seeds require 36 hours of continuous red light for maximal percent germination. The optimal photoinduction temperature is 32°C, with higher and lower temperatures b
