3. O COMPORTAMENTO VOCAL ENTRE ESCOLARES COM QUEIXAS VOCAIS, COM E SEM HISTÓRIA DE SITUAÇÃO DE RUA, EM ARACAJU, BRASIL
Objective: it is to compare the frequency of vocal, acoustical and otorhinolaryngological alterations among students who present vocal complaints and street background or not. Method: cross sectional with control group. A random sample of 200 students with a street situation background was selected, aging from 07 to 10, both male and female and all took part

5. Espectroscopia de galáxias em sistemas múltiplos
Neste trabalho foram reduzidos e analisados espectros ópticos de sete objetos em sistemas múltiplos - grupos e pares, sendo eles NGC 3819 e suas companheiras H58D1 e H58D2, cujos mesmos espectros já foram objeto de estudo de Landin (2002), ESO-LV 5100550, o par ESO-LV 5520490 e ESO-LV 5520500 e UGC 4703, que é um par de galáxias anãs ligadas, no plano

6. Spectrographic and nasometric profiles of the vowel [a] its counterpart [ã] in experimental conditions of the velopharyngeal coupling / Perfil espectrográfico e nasométrico da vogal [a] e sua contraparte [ã] em diferentes condições de abertura velofaríngea
Hypernasality is a resonance disorder due to the coupling between the oral and nasal cavities, usually associated to velopharyngeal dysfunction. The relationship between size of velopharyngeal opening and speech hypernasality is not a well understood phenomenon. Particularly, little is known between the acoustic profiles of vowels under differents conditions

7. Recuperação da difusão fonetica em individuos desdentados com emprego de proteses totais duplas confeccionadas com base na tecnica da zona neutra
Although several studies have been published about toothless patients rehabilitated with Double Total Prosthesis, this subject has not yet been fully considered as to its physiological, social or emotional aspects. By means of Spectrography, the intensity of sound of the consonant "5" and of the vowels "A", "E", " I" , and "O" was analyzed in five Brazilian

8. Parassexualidade e produção de destruxinas em linhagens de metarhizim anisopliae var. anisopliae (Metsch.) sorokin
In this work the main object was the study of destruxlns production, by diploids and segregants obtained through parasexual cycle in Metarhizium anisopliae. The two parantal strains utilized were E-9 (Brazil) and F-84 (USA), which after induction with UV-radiation produced conidial color and auxotrophic mutants. The mutants E-9 am-pir, F-84 vio-tia and F-84

9. Aquecimento do plasma por radio frequencia na maquina linear lisa
We show in this work the characteristics of an experimental device assembled in the Instituto de Física, Universidade Federal Flurninense (Linear Mirror Type Machine LISA) to produce Helium plasma by RF and to study its behavior when confined by a magnetic field with mirrors. The plasma was produced by a micro-wave generator of, fRF = 2.45 GHz, PRF = 800 Wa

10. Distribution of Foliar-applied Boron Measured by Spark-source Mass Spectrometry and Laser-probe Mass Spectrography
The distribution of foliar-applied boron ([10B]boric acid) in radish (Raphanus sativus L.) was studied using for analysis of the stable isotopes a technique allowing a high sensitivity: spark-source mass spectrometry. Boron was recovered in the nontreated aerial parts and in the roots; however, the greatest fraction was in the treated leaf. It was possible w

11. Metabolism of 14C-Zeatin in Phaseolus Embryos 1: Occurrence of O-Xylosyldihydrozeatin and Its Ribonucleoside
The metabolism of trans-[8-14C]zeatin was examined in embryos of Phaseolus acutifolius A. Gray P.I. 321637 and Phaseolus coccineus Lam. cvs Scarlet Runner and Desiree. In both species zeatin was converted to ribosylzeatin, ribosylzeatin 5′-monophosphate, O-glucosyl-9-ribosylzeatin and the recently discovered O-xylosyl derivatives of zeatin and ribosylzeati

12. Odorous Sulfur Compounds Emitted during Production of Compost Used as a Substrate in Mushroom Cultivation
Large-scale composting facilities are known to cause environmental problems, mainly through pungent air emitted by composting material. In air samples taken above stacks set up to prepare compost used as a substrate in mushroom cultivation, several volatile compounds were identified by means of the coupled techniques of gas chromatography and mass spectrogra
