Natália Ueda Yamaguchi3,5 RESUMO Água que chega às residências nem sempre é de qualidade assegurada. Isto ocorre devido a diversos fatores, tais como deficiências no sistema de distribuição de água tratada e no tratamento da mesma. A partir do Standard methods for examination of water and wastewater (APHA et al., 2012) e com embasamento na NBR 16098 (ABNT, 2012), foi monitorada e caracterizada a qualidade da água em 21 pontos (bebedouros, poço e torneira), do Centro Universitário de…

dimethylformamide can be used in the coupling reaction. Such coupling in organic solvents is necessary for many ligands and may be necessary for the immobilization of proteolipids and hydrophobic peptides. The epoxy activation of the carrier can also be the method of choice because it offers a very high flexibility in the reaction conditions. Although glucans such as cellulose, modified starches and gellan (Abdulhareem, Bryjak, Markiewiez, & Croch, 2002; Sankpal and Kulkarni, 2002) have…

real dental needs of Thai primary school children, and integrated an oral health-related quality of life measure (OHRQoL) into oral health service planning. We then compared the results of this sociodental assessment with standard estimates of a child’s oral health needs. Methods We developed a new model of sociodental needs assessment and used it to assess the level of impact that various oral health conditions have on the everyday lives of school children. We then carried out a cross…
