in this research, the effect of different concentrations of pectinase has been investigated on deinking of old newspaper (onp). onp re-pulped at 5% consistency for 10 min in disintegrator (with 2650 rpm). enzymatic treatment of recycled onp pulp was done under constant conditions (10% consistency, duration time of 20 min, ph range of 4.5-5) at different pectinase concentrations (0.05, 0.1, 0.2,...

Diabetes mellitus is a chronic disease which affects the healing ability of the pulp and periodontium. The aim of the present study was to assess the histopathologic response of dental pulp to pulp capping using MTA or CEM cement in diabetic rats. Thirty two Wistar male rats aged between 8 and 10 weeks (weight: 200-250g) were divided into two groups of diabetic (n=16) and healthy (n=16) animals...

The present experiment aimed at increasing orange peel and sugar beet pulp protein content through solid-state fermentation by Trichoderma reesei and Trichoderma viride. In vitro digestibility and changes in the chemical composition of the fermented products were determined after seven days of fungal cultivation using gas production tests. The cultivation of T. reesei and T. viride on orange pe...

Cultivar Solar was developed specifically for the edaphoclimatic conditions of State Mato Grosso. It has improved fruit physical and chemical characteristics, such as higher weight, total soluble solids content pulp percentage, is suitable both fresh consumption processing industry.

Abstract This study evaluates the use of fermentation to increase nutrient availability in pulp and paper bio-sludge (PPBS) as feed for black soldier fly larvae (BSFL). Rearing BSFL on fermented PPBS was carried out a climate chamber order assess survival growth. The used came from chemo-thermomechanical pulp/groundwood mill. at 35 °C 55 °C, respectively, initial pH 10. effects sediment liquid ...

diabetes mellitus is a chronic disease which affects the healing ability of the pulp and periodontium. the aim of the present study was to assess the histopathologic response of dental pulp to pulp capping using mta or cem cement in diabetic rats. thirty two wistar male rats aged between 8 and 10 weeks (weight: 200-250g) were divided into two groups of diabetic (n=16) and healthy (n=16) animals...

Peach (Prunus persica L.), being a potential source of bioactive compounds, has been demonstrated to have medicinal benefits. In this study variation of minerals and antioxidant characteristics (total phenolic contents, total flavonoid contents, reducing power, inhibition of peroxidation using linoleic acid system and DPPH free radical scavenging activity) between peel and pulp parts of differe...

The effect of residual lignin content on the mechanical strength and water absorption of kraft pulp/ polypropylene composites was studied. To meet this objective, hornbeam wood chips were converted to kraft pulp at three different alkalinities (15, 20, and 25%) and three different cooking times (60, 90, and 120 min). The residual lignin contents of these pulps were determined according to the T...

This study investigated the potential of oleaginous yeast Rhodotorula glutinis utilizing pulp and paper wastewater effluents as cultivation media for the sustainable production of microbial lipids as biodiesel feedstock. R. glutinis is oleaginous yeast, which has the ability to produce significant quantities of intercellular lipids in the form of triacylglycerols. Yeast lipids are a promising p...

The aim of this study was to evaluate the tissue dissolution ability of different irrigating solutions associated or not to ultrasonic agitation. Ninety bovine pulp fragments (n=10 per group) were weighed and then placed individually in Eppendorf test tubes containing the following irrigants: G1- 2.5% sodium hypochlorite (NaOCl); G2- 2.5% NaOCl + ultrasonic agitation (US); G3- 2.5% NaOCl + 0.2%...
