Este material didático é elaborado com base nos estudos e em uma experiência situação real de sala aula, o uso histórias quadrinhos (HQs) turma do segundo ano Ensino Médio. Inicialmente, trazemos alguma discussão a respeito das HQs possibilidades para sua utilização na disciplina Química partir dos resultados discutidos literatura. A produzidas pelos próprios estudantes retomada conteúdos essen...

Background & Aims of the Study: The main objectives of the current research were (1) to study the extent of soil pollution by heavy metals (Ag, Cd, Cr, Cu, Mn, Ni, Pb, Zn, Ba and Li) in sampling locations (2) to investigate the extent of heavy metal pollution and soil to plant transfer of these elements in wheat and barley (3) to study the health risk of heavy metals via consum...

a study was conducted to standardize production and postharvest handling of lily (lilium longifolium l. cv. mero star). in production trial, three plant densities viz.10, 20 and 30 cm between plants in 60 cm spaced rows and two planting depths viz.7.5 and 15 cm were compared. increased plant growth, yield and quality was recorded when plants were grown at a close spacing of 10 cm with 15 cm pla...

Within the framework of a constituent quark model, we investigate heavy conserving weak decays ?c and ?b. This process involves elementary transitions us?du or s?udu¯ with as spectator, while for charmed baryon in initial state it can also occur via cs?dc to conserve flavor decays. It shows that symmetry (HQS) plays an essential role processes where acts spectator. For decays, dominance pole te...

A construção de Histórias em Quadrinhos - HQs na escola Educação do Campo (CALDART, 2004) é uma alternativa didática para trabalhar sala aula (VERGUEIRO, 2014), por meio que representem o sócio histórico das comunidades Assentamento Agrícola Vila Amazônia Parintins, Amazonas. O objetivo deste artigo demonstrar a utilização escolas Assentamento, partir da concepção Campo, através histórias orais...

In this study, we proposed a Regional Probabilistic Risk Assessment (RPRA) to estimate the health risks of exposing residents to heavy metals in different environmental media and land uses. The mean and ranges of heavy metal concentrations were measured in water, sediments, soil profiles and surface soils under four land uses along the Shunde Waterway, a drinking water supply area in China. Haz...

In this paper we present a detailed formulation for a recently proposed effective field theory to describe the nonperturbative QCD dynamics of heavy mesons. This effective theory incorporates with heavy quark symmetry (HQS) and the heavy quark effective theory (HQET). Heavy mesons in this theory are constructed as composite particles of a heavy quark bounded with the light degrees of freedom. T...

Concentrations of polybrominated diphenyl ethers (PBDEs), and organochlorine pesticides (OCPs; DDTs, HCHs, CHLs, and HCB) were measured in human breast milk samples collected across Massachusetts, USA, in 2004. Seventeen PBDE congeners were found in the samples, ranging in concentration from 0.06 to 1910 ng g(-1) lipid wt. BDE-47 (2,2',4,4'-tetraBDE), BDE-99 (2,2',4,4',5-pentaBDE), and BDE-100 ...
