HIGH STRENGTH PAPER PRODUCTION BASED ON ESTERIFICATION OF THERMOMECHANICAL PULP FIBERS IN THE PRESENCE OF POLY(VINYL ALCOHOL)

High strength paper production based on esterification of thermomechanical pulp fibers in the presence of poly(vinyl alcohol)

Thermomechanical pulp (TMP) fibers, generally used to produce newspapers and carton materials, have poor inter- and intra-fiber bonding contributing to low strength properties.Poly(vinyl alcohol) (PVOH) GOLD X GEL PACK was applied as a co-additive of 1,2,3,4-butanetetracarboxylic acid (BTCA), in the presence of sodium hypophosphite (SHP) as a catal

Endocrine Control of Postnatal Growth in Poultry

This paper provides an overview on the role of several Loaf Pans endocrine factors in the regulation of the somatic growth (skeletal muscle and bone development) and body composition in meat-type poultry.The hormones of both the somatotrophic axis (GH and IGFs) and the thyrotrophic (T4, T3) axis are a prerequisite for normal growth and development.

Defect Localization Inside Simulated MV Switchgear Based on Cumulative Energy Curve Using Transient Earth Voltage Sensors

The partial discharge (PD) leads to catastrophic failure of the medium voltage (MV) switchgear insulation.Determination of the PD source (defect) location in high voltage (HV) equipment is very important in the maintenance procedures and in isolating the root cause of PD generation.In this paper, the transient COCK CAGE earth voltage (TEV) detectio
