Model approach for estimating potato pesticide bioconcentration factor
(Pergamon-Elsevier B.V. Ltd, 2008-11-01)
We presented a model that estimates the bioconcentration factor (BCF) of pesticides in potatoes supposing that the pesticide in the soil solution is absorbed by the potato by passive diffusion, following Fick's second law. ...
Layer by layer TiO2 thin films and photodegradation of Congo red
(Elsevier B.V. Sa, 2011-04-30)
Layer by layer (LbL) self-assembled technique was used to fabricate TiO2 films onto glass and quartz slides. The LbL sequence was PAH/PSS/TiO2(PSS/TiO2)(5) (PSS = poly(sodium-4-styrene sulfonate), PAH = poly(allylamine ...

Influence of ionic interactions on the photoinduced Birefringence of poly[1-[4-(3-carboxy-4 hydroxyphenylazo) benzene sulfonamido]-1 2-ethanediyl, sodium salt] films
(Amer Scientific Publishers, 2007-08-01)
Electrostatic interactions govern most properties of polyelectrolyte films, as in the photoinduced bire-fringence of azo-containing polymers. In this paper we report a systematic investigation of optical storage characteristics ...

Chromosome aberration and micronucleus frequencies in Allium cepa cells exposed to petroleum polluted water - A case study
(Elsevier B.V., 2008-01-31)
In the present study, we applied Chromosome Aberration (CA) and Micronucleus (MN) tests to Allium cepa root cells, in order to evaluate the water quality of Guaeca river. This river, located in the city of Sao Sebastiao, ...
Electrooptic proprieties of layer-by-layer films of a azobenzene containing copolymer
(2005-12-01)
The methacrylic copolymer functionalized with the azo chromophore 4-[N-ethyl-N-(2-hydroxiethyl)]-amino-2′-chloro-4-nitroazobenzene (MMADR13), in its polyelectrolyte form, can be used to fabricate thin films by the ...
Data on hydrocarbons in sediment samples, and its body burden levels in tissues of Anomalocardia flexuosa from toxicity testing
(2020-08-01)
The analysis of hydrocarbons in terms of individual compounds is relevant to understand the origin and source of these substances, as well as its distribution in environmental compartments, including sediments and biota. ...
GnRH analog is ineffective in increasing adult height in girls with puberty onset after 7 years of age: A systematic review and meta-analysis
(2018-12-01)
Objective: We assessed the effectiveness of puberty blockade with a gonadotropin-releasing hormone (GnRH) analog in increasing adult height (AH) in girls with puberty onset between 7 and 10 years of age. Methods: We performed ...
