Nickel exposure from keys: a Brazilian issue*
نویسندگان
چکیده
Keys are a significant source of exposure to metal allergens and can be a relevant problem for nickel-allergic individuals. This study aimed to perform nickel and cobalt spot testing among the 5 most common Brazilian brands of keys. Among the tested keys, 100% showed positive result to nickel spot test, 83,3% presented strong positive reaction. 50% exhibited cobalt release as well. Nickel release from keys is very common in our country and may cause a negative impact on sensitized individual's quality of life. Study's results highlight the importance of establishing directives to regulate nickel release in Brazil.

‘Minor’ Languages, ‘Broken’ Translations: On Brazilian Reworkings of an Albanian Novel
This essay approaches the challenges of global translation in the 21st century from what might still be considered a somewhat uncommon example: a direct translation of Ismail Kadaré's 1978 novel Prill e thyër (Broken April) from the original Albanian into Brazilian Portuguese in 2001. Not only does it examine and compare lexical elements in the source and target texts and the usage of translato...
متن کاملScreening of Trichoderma isolates for their potential of biosorption of nickel and cadmium
Fourteen Trichoderma isolates were evaluated for their tolerance to two heavy metals, nickel and cadmium. Three isolates, MT-4, UBT-18, and IBT-I, showed high levels of nickel tolerance, whereas MT-4, UBT-18, and IBT-II showed better tolerance of cadmium than the other isolates. Under nickel stress, biomass production increased up to a Ni concentration of 60ppm in all strains but then decreased...
