Every day digital resources protection is an appealing research area because the amount of e-documents transmitted over non-secure channels such as the Internet has increased considerably. So, secure mechanisms must be implemented to identify illegal copies of crucial information. Many researchers have proposed solutions based on controlled environments applying asymmetric cryptography. Other researchers have applied some techniques such as steganography, cryptography and security protocols to deal with uncontrolled environment. This paper presents a secure framework to sign and authenticate remotely digital documents focused on uncontrolled environment. The framework is compound by various security protocols used to ensure authentication and confidentiality in each of the services. Each of protocols has been formally verified using The AVISPA tool and we found that they provide strong authentication and privacy security properties. In addition, the framework has also been adapted to work with TLS and SSL protocols because they are the standard in e-commerce. [ABSTRACT FROM AUTHOR]

The article presents information on a study which examined a fuzzy logic approach that uses a lighter power source for Automatic Monitoring Stations in the Arctic. Special considerations for equipment operating in Arctic regions that are working under extreme weather conditions are listed, including seasonal access to remote Arctic locations. Fuzzy power management involves one output and two inputs for the fuzzy controller, fuzzy control system rules, and a continuous fuzzy controller.

Information about several papers discussed at the International Textile Manufacturers Federation (ITMF) Annual Conference which was held in São Paulo, Brazil from October 17-19, 2010 is presented. Topics include the market profile, condition and outlook of the textile and clothing industry in the country. The conference featured Fernando Pimentel, executive director of the Brazilian Textile and Apparel Industry Association (ABIT).

The objective of this work was to study the dermal exposure of workers to residues of the deltamethrin, applied in cotton. After 3 minutes of application four people dressed a group with cotton clothes (pants, shirt and gloves), entered and stayed in the treated area by 30 minutes, simulating a sampling. The procedure was repeated after 60 and 300 minutes and 1, 3, and 7 days after the application. The clothes were cut and put in plastic bags, and stored cold at -18°C (-0.4°F) until analyses was performed. The analytical method consisted on the extraction of deltamethrin residues with ethyl acetate and the quantitative determination was done by gas chromatography. Exposure was extrapolated to a workday of 8 hours. To evaluate safety's conditions at work was estimated the Working Condition Unsafe (margin of safety - MOS <1), Poisonous Dose (%PD/day), Dermal Dose Tolerable and the estimate of Safe Work Duration (SWD). The corresponding group for the forearms/arms/hands concentrated 61.27% of present residues in the clothes. The residues found on the clothes, chest, legs, thighs and back, were 13.40, 9.33, 9.32, and 6.65%, respectively. Results of deltamethrin amounts trapped on cotton clothes showed that 24h as a re-entry interval for Decis 25 EC is overestimated in Brazil. [ABSTRACT FROM AUTHOR]
