Kraft lignin: Kraft lignin-based controlled release formulation for pest control. Infoteca-e
VAZ JUNIOR, S..
A formulation that uses lignin obtained by precipitation of black liquor from the kraft pulping process of the pulp and paper industry as an inert material for adsorption and desorption of the semiochemical cis-Jasmone for use in integrated pest management (IPM), through controlled release.

Basic density and pulp yield relationship with some chemical parameters in eucalyptus trees PAB
Seca,Ana Maria Loureiro da; Domingues,Fernando Manoel de Jesus.
The objective of this work was to evaluate the use of basic density and pulp yield correlations with some chemical parameters, in order to differentiate an homogeneous eucalyptus tree population, in terms of its potential for pulp production or some other technological applications. Basic density and kraft pulp yield were determined for 120 Eucalyptus globulus trees, and the values were plotted as frequency distributions. Homogenized samples from the first and fourth density quartiles and first and fourth yield quartiles were submitted to total phenols, total sugars and methoxyl group analysis. Syringyl/guaiacyl (S/G) and syringaldehyde/vanillin (S/V) ratios were determined on the kraft lignins from wood of the same quartiles. The results show the...

Thermal and spectroscopic analyses on the molecular interaction between eucalyptus kraft pulp components and offset printing inks BABT
Alves,Ericka Figueiredo; Oliveira,Rubens Chaves de; Silva,Luis Henrique Mendes da; Colodette,Jorge Luiz.
Thermal and infrared spectroscopic analyzes were carried out in order to study the kind of interaction between the anatomical components of the bleached eucalyptus kraft pulp with offset inks. A Bauer-McNett fiber classifier was used in order to obtain the anatomical components of the pulp, separately. The determinations of the enthalpy of the processes occurring in the samples of inks and pulp, as well as the enthalpy of these components interactions were obtained by Differential Scanning Calorimetry. In the interaction between pulp and offset ink, the reduced enthalpy values of the endothermic peak were interpreted as due to the released energy for adhesion of the ink pigment to the substratum. The low enthalpy value, 58 to 121 cal.g -, ¹indicated that...
