The novel and facile multi-stage method was used for the conversion of bamboo into nanocellulose single cell protein. Firstly, chips were treated with sodium hydroxide solution followed by hydrogen peroxide bleaching obtaining cellulose pulp a brightness 80% ISO. In second stage, obtained bleached cellulosic achieved dilute sulfuric acid filtration sugar solution, which than Candida utilis cult...

Data from two thermo-mechanical pulp mills are collected to simulate the refining process using deep learning. A multilayer perceptron neural network is utilized for pattern recognition of variables. Results show impressive capability artificial intelligence methods in energy simulation so that correlation coefficient 98% accessible. comprehensive parametric study has been made investigate effe...

Basic fiber properties can be classified into four categories: Size distribution, shape, structure of the cell wall and the fiber surface. This approach was used when long fiber fractions separated from 10 different mechanical pulps and unrefined and refined chemical pulp samples were compared in order to shed light on the different reinforcing abilities of chemical and mechanical pulp fibers. ...

Abstract The specific surface area (SSA) of cellulosic or lignocellulosic fibers is seldom reported in the recent literature on papermaking, despite its close relation with degree refining and other key pulp properties. Amidst outdated assays (Pulmac permeability test) methods that, while accurate, are doubtful usefulness for papermaking purposes (N 2 adsorption–desorption), we suggest a method...

The foam that occurs in the process can cause problems with effectiveness of or quality final product. economic consequences uncontrolled foaming be very significant and serious losses require expensive operating changes. Foaming just as treating other types problems, such corrosion, fouling, emulsion. Indonesia is known largest producer palm oil, so it has potential a downstream oil derivative...

Restorative and endodontic procedures have been recently developed in an attempt to preserve the vitality of dental pulp after exposure to external stimuli, such as caries infection or traumatic injury. When damage to dental pulp is reversible, pulp wound healing can proceed, whereas irreversible damage induces pathological changes in dental pulp, eventually requiring its removal. Nonvital teet...
