Dioxins are a group of anthropogenic chemical compounds created as unintended by-products through a number of activities including: combustion, certain types of chemical manufacture, chlorine bleaching of pulp and paper, and other industrial processes. Dioxins are produced in very small quantities compared to other pollutants; however, because this family of compounds are thought to be highly t...

Brazilian savanna constitutes a valuable ecoregion that contributes to the supply of fruit known worldwide for its nutritional value and peculiar flavors. Among them, the Marolo (Annona crassiflora Mart.) fruit is known for its use in folk medicine. In order to establish the safety of Marolo for human consumption, this study evaluated the following: the chemical composition of Marolo pulp; its ...

Process intensification is a term used in the chemical process industry for major improvements in the process design leading to radical changes in process complexity, equipment size and efficiency. We suggest that a similar approach is applied in the pulp and paper industry. We have focused on the production of mechanical pulp, but a similar approach can be applied to other areas within the pul...

the efficiency of oxidation processes, enzymatic treatment, and combined enzymatic/chemical sequences on color remediation of cmp pulp mill effluent was investigated. two kinds of fungal enzymes; laccase (ec: 1.10.3.2) from terametes versicolor and versatile peroxidase (ec: 1.11.1.7) from bjerkandera adusta were chosen and applied. also, the effect of external mediator on the enzyme based degra...

The leaf pulp of Aloe vera Tourn. ex Linn., designated as the gel, and the bitter, yellow liquid fraction have been tested against pathogens (bacteria and fungi) affecting human and plants. However, their activity for fungal control in commercial industrial crops has not been determined. Thus, researchers at Mexico carried out studies to evaluate the inhibitory effect of Aloe pulp and liquid fr...

BACKGROUND In the coming years, a nutraceutical food may provide both physical and mental benefits that are commonly attributed to the active components of the food. OBJECTIVE In this study, we determined the nutrient and mineral contents, sensory properties, and physical and chemical characteristics of ice creams manufactured using peach fibre at different concentrations (1 and 2%). METHOD...

Previous studies have identified chemical recovery condensates as a primary source of hormonally active substances within a Canadian bleached kraft pulp mill. Although reverse osmosis treatment of condensates raises the exposure threshold that alters circulating levels of testosterone in mummichog (Fundulus heteroclitus), the responsible chemicals have not been characterized. In this study, a s...

Dental pulp tissue supports the vitality of the tooth, but it is particularly vulnerable to external insults, such as mechanical trauma, chemical irritation or microbial invasion, which can lead to tissue necrosis. In the present work, we present an endodontic regeneration method based on the use of a tridimensional (3D) hyaluronan scaffold and human dental pulp stem cells (DPSCs) to produce a ...
