1. Investigations of the prevalence and virulence of Candida albicans in periodontal and endodontic lesions in diabetic and normoglycemic patients
Abstract Pulpal and periodontal tissues have similar microbiota that allows cross-contamination between the pulp and periodontal tissues. Objective The aim of this study was to investigate the prevalence of isolated Candida albicans from periodontal endodontic lesions in diabetic and normoglycemic patients, and the fungi's virulence in different atmospheri

2. A model for implementation of HACCP system for prevention and control of mycotoxins during the production of red dried chili pepper
Abstract Hazard analysis and critical control points (HACCP) is a process control system describes the potential hazards during food production flow chart. In contrast to the conventional way of ensuring product safety by end-product testing, HACCP establishes control systems, focuses mainly on preventive measures. Quality of red dried chili pepper (RDCP) sh

3. Application of post-discharge region of atmospheric pressure argon and air plasma jet in the contamination control of Candida albicans biofilms
Introduction:Candida species are responsible for about 80% of hospital fungal infections. Non-thermal plasmas operated at atmospheric pressure are increasingly used as an alternative to existing antimicrobial strategy. This work investigates the action of post-discharge region of a non-thermal atmospheric plasma jet, generated by a gliding arc reactor, on bi

4. Thermal processes for lead removal from the funnel glass of CRT monitors
The disposal of CRT monitors increases each year, generating millions of tons of waste containing various types of materials. The glass present in CRT tubes displayed about 20%-25% of lead oxide. If improperly disposed of, this glass can be leached directly in nature or may cause environmental contamination, especially with lead. Because of this leaching pos

5. Are bovine teeth a suitable substitute for human teeth in in vitro studies to assess endotoxin load in root canals?
The present study aimed to determine the feasibility of using bovine teeth as a suitable alternative for human teeth, in experiments involving in vitro endotoxin contamination. Twenty bovine central incisors and 20 human single-root premolars had their dental crowns removed and root lengths set at 16 mm. Root canals were prepared up to #60 K-file size and st

6. Avaliação da qualidade da água de chuva e de um sistema filtro-vala-trincheira de infiltração no tratamento do escoamento superficial direto predial em escala real em São Carlos SP / Evaluation of rainfall water quality and a filter-swaleinfiltration trenches system in the treatment of the building direct runoff in real scale in são carlos sp
Several studies cite the pollution of stormwater as equivalent and sometimes even superior to those found in the sewers. According to this premise and thinking about environmental issues, especially in the contamination of groundwater and the spread of waterborne diseases, the quality of rainwater has become an important focus of study. This work concerns th

7. Otimização e validação de método empregando SPE e LC-APCI-MS/MS para determinação de fármacos em água de superfície e de abastecimento público / Optimization and validation method for using SPE LC-APCI-MS/MS and determination of pharmaceuticals in surface water and public water supply
The global use of drugs classified as emerging contaminants has become a new environmental problem due to possible contamination of surface and supply water and may impact the environment and cause harm to public health. In the city of Rio Grande, RS, Brazil, the supply of drinking water is accomplished by CORSAN (Companhia de Saneamento Riograndense), which

8. Poluentes orgânicos persistentes na biota marinha do Arquipélago de São Pedro e São Paulo / Persistents Organic Pollutants in marine biota of the São Pedro e São Paulo Archipelago
Some oceanic islands, such as São Pedro e São Paulo Archipelago may be considered remote areas and preserved due to its distance from the mainland. However, these areas are not exempt from the influence of anthropogenic agents from coastal regions, such as persistent organic pollutants (POPs). This proposal aimed to determine the occurrence and distributio

9. Utilização de líquens como bioindicadores de contaminação atmosférica por radionuclídeos naturais e metais em região impactada por TENORM / The use of lichens as bioindicators of atmospheric contamination by natural radionuclides and metals in a region impacted by TENORM
The main aim of this thesis is to study the possibility of using lichen as bioincicator of atmospheric pollution in regions contaminated by radionuclides, metals and rare earth elements. Two regions were chosen, one in Pirapora do Bom Jesus, where a tin and lead industry is located, and a second one in Cubatão, where a phosphate fertilizer industrial comple

10. SIMULATION OF THE VERTICAL TRANSPORT OF ZINC, LEAD AND COPPER IN CONTAMINATED SOILS / SIMULAÇÃO DO TRANSPORTE VERTICAL DE ZINCO, CHUMBO E COBRE EM SOLOS CONTAMINADOS
The environmental contamination by metallic trace elements is a problem that is getting worse around the world due to the growth and the technologic development of the humanity. Among the main sources of this kind of contamination are the atmospheric deposition of particles in soils located around industrial complexes and the prolonged and concentrated appli

11. Remote sensing of aerossol with high spacial resolution in amazon region / Sensoriamento remoto de aerossóis em alta resolução espacial na região amazônica
The significant deforestation process in Amazonia results in high levels of aerosols and trace gases emitted to the atmosphere. It is necessary the development of tool that allows a better quantification of the atmospheric aerosol loading and consequently the impact on regional climate, including changes in the regional radiation balance and the mechanisms o

12. Policyclyc aromatic hidrocarbons study at São Vicente and Santos Estuaries SP using diatomite as adsorbent material / Estudo de hidrocarbonetos policíclicos aromáticos nos estuários de Santos e São Vicente/SP utilizando diatomito como material adsorvente
Diatomite spheres were used as an adsorbent material for policyclyc aromatic hidrocarbons (PAH) adsorption at water column for the identification of the main contamination sources at two estuaries of Baixada Santista. The samples were held at Santos Estuary (site 1) and São Vicente Estuary (site 2) during the year 2006, at two sites, and in 2007, only at si
