1. Mapping Forest Landscape Multifunctionality Using Multicriteria Spatial Analysis
ABSTRACT This paper presents a GIS methodological approach for mapping forest landscape multifunctionality. The aims of the present study were: (1) to integrate and prioritize production and protection functions by multicriteria spatial analysis using the Analytic Hierarchy Process (AHP); and (2) to produce a multifunctionality map (e.g., production, protect

2. Levantamento de plantas de baixa inflamabilidade em áreas queimadas de Cerrado no Distrito Federal e análise das suas propriedades físicas
Resumo Os incêndios florestais se propagam principalmente através do material combustível superficial. Portanto, plantas de baixa inflamabilidade podem ser usadas para proteção contra incêndios, pois dificultam a propagação do fogo. Neste sentido, o objetivo deste trabalho foi realizar um levantamento de plantas de baixa inflamabilidade no cerrado do

3. Intumescent Coatings Based on Tannins for Fire Protection
Accidents involving fire occur every day around the world, affecting thousands of people and causing economic losses. Some accidents are caused by steel structure failures, which experience a significant reduction in mechanical properties at temperatures of 400-550˚C. Therefore, fire protective coatings are required for steel structures and interest in the

4. Protection of Grid Connected Photovoltaic Systems (GCPVS)
ABSTRACT Installations of photovoltaic systems connected or not to the electrical network have become increasingly popular, but it is often carried out by unqualified people using low quality components. The present study aims to describe the methodology adopted for the protection of grid connected photovoltaic systems (GCPVS) and the implications caused by

5. Post-fire resprouting strategies of woody vegetation in the Brazilian savanna
ABSTRACT Post-fire response by vegetation may reflect the severity of the damage suffered, but we still know little about the species-specific nature of responses to fire or their predictors. Here, we evaluated 26 woody species before and after a fire event in an Cerrado sensu stricto area (typical Brazilian savanna-type) in order to evaluate mortality rates

6. Influence of vegetation physiognomy, elevation and fire frequency on medium and large mammals in two protected areas of the Espinhaço Range
ABSTRACT The objectives of this study were to determine the richness of medium and large mammal species in two protected areas of the Espinhaço Mountain Range, state of Minas Gerais, Brazil; and to investigate the factors affecting the occurrence of those species. To accomplish that we placed 49 camera traps activated by heat and motion at Rio Preto State P

7. HOT AEROSOL FIRE EXTINGUISHING AGENTS AND THE ASSOCIATED TECHNOLOGIES: A REVIEW
Abstract Since the phase out of Halon extinguishers in the 1980s, hot aerosol fire suppression technology has gained much attention. Unlike traditional inert gas, foam, water mist and Halon fire suppression agents, hot aerosol fire extinguishing agents do not need to be driven out by pressurized gases and can extinguish class A, B, C, D and K fires at 30 to

8. Fire Resistant Aircraft Unit Load Devices and Fire Containment Covers: A New Development in the Global Air Cargo Industry
ABSTRACT: Unit load devices (ULDs) are pallets and containers which are used to carry air cargo, mail and passenger baggage on wide-body aircraft. This paper analyses two important recent developments in the suppression of fires on freighter aircraft - fire resistant containers and fire containment covers for palletised cargo. In July 2013, United Parcel Ser

9. Strengthening the composite protective shield of light-weight ship against ballistic impacts: analytical and experimental
Light and medium protection for small naval vessels guarantees their high performance and safety during the guard duties. In this study, a protective shield fabricated from Dyneema HB25 fibers has been utilized as an add-on layer on the coast guard boat hull. Finite element analyses have been conducted using Chocron's model. Two standards of gun-fire were em

10. Arquitetando a segurança contra incêndio / Architecting fire safety
O trabalho apresenta a evolução da segurança contra incêndio no Brasil, decorrente fundamentalmente dos incêndios nos edifícios Andraus e Joelma, em São Paulo, no início dos anos 70, com especial atenção à evolução da regulamentação exarada pelo Poder Público e que impacta o ambiente construído dos edifícios. Utilizando dados primários, de

11. Modelos numéricos de vigas mistas de aço e concreto pertencentes a sistemas de pisos mistos de pequena altura em situação de incêndio / Numerical modelling of composite slim floor beams in fire
Slim floor frames consists on structural system in which the steel beam is completely or partially inserted in a concrete slab, that is usually used in profiled steel decks systems. The main goal of the slim floor systems is to obtain a minimum height of the composite beam section and, consequently, achieve a higher height of the floor or a lower total heigh

12. Um estudo dos processos de regulação e governança socioambiental do setor sucroalcooleiro no Brasil
In the last five years, there was an increase the ethanol production in Brazil, thanks to the ex-pansion of this sector in the Brazilian Cerrado. Despite all the scientific and technological development for sustainable production of ethanol, the environmental, social and labor also affect the credibility of the product, both domestically and externally. Alon
