PENYEMPURNAAN SIFAT PAPAN SERAT KERAPATAN SEDANG DARI PELEPAH NIPAH DAN CAMPURANNYA DENGAN SABUT KELAPA

Jurnal Penelitian Hasil Hutan (Journal of Forest Products Research), 2013
Dewasa ini, potensi bahan serat konvensional (khususnya kayu) untuk pembuatan papan serat berkerapatan sedang (MDF) semakin terbatas dan langka. Penggunaan bahan serat alternatif yang tersedia berlimpah dan belum banyak dimanfaatkan, yaitu pelepah nipah ...

Fractionation of Waste MDF by Steam Refining [PDF]

Molecules, 2020
In view of the expected increase in available waste medium-density fiberboard (MDF) and the current insufficient and unsatisfactory disposal capacities, efficient ways of recycling the waste material need to be developed. In this study, the potential of steam refining as a method to hydrolyze the resins, isolate fibers, and obtain a hemicellulose-rich ...

Prediction of screw withdrawal resistance for plywood laminated panels and sandwich panels

Turkish Journal of Forestry
Sandwich panels are favorable materials for structural or non-structural components due to durability, lightness, and longevity in service life. This study aimed to predict screw withdrawal resistance of the plywood laminated medium-density fiberboard ...

Constitutive Model and Microstructure Evolution Finite Element Simulation of Multidirectional Forging for GH4169 Superalloy

Metals, 2020
This study investigates three processes of multidirectional forging (MDF), namely, closed MDF (CMDF), single-open MDF, and double-open MDF, by using a constitutive equation and a dynamic recrystallization model of hot deformation of the GH4169 superalloy.

The stellar content of the Hamburg/ESO survey VI. The metallicity distribution of main-sequence turnoff stars in the Galactic halo

, 2010
We determine the metallicity distribution function (MDF) of the Galactic halo based on metal-poor main-sequence turnoff-stars (MSTO) which were selected from the Hamburg/ESO objective-prism survey (HES) database.

Is the metallicity of their hosts a good measure of the metallicity of Type Ia supernovae? [PDF]

, 2011
The efficient use of Type Ia supernovae (SNIa) for cosmological studies requires knowledge of any parameter that can affect their luminosity in either systematic or statistical ways.

Prenatal exposure to antihypertensive medication: A systematic review of neurodevelopmental and educational outcomes

JCPP Advances, EarlyView.
This systematic review investigated the association of prenatal exposure to antihypertensive medication with longer‐term poor neurodevelopmental outcomes by evaluating the findings from existing literature. We undertook a systematic review of previous studies looking specifically at neurodevelopmental outcomes in children.

Effects of Nanoclay Modification with Aminopropyltriethoxysilane (APTES) on the Performance of Urea–formaldehyde Resin Adhesives

BioResources, 2023
Urea-formaldehyde (UF) resins, as the most common adhesives for wood-based composites, emit formaldehyde, which is forcing producers to find a solution to this problem. Using scavengers is a practical way of reducing formaldehyde emissions, but sometimes
