Highly compressible paracetamol — II. Compression properties

International Journal of Pharmaceutics, 2000
Paracetamol particles crystallized in the presence of polyvinylpyrrolidone (PVP) exhibited an obvious improvement in their compression properties compared to untreated paracetamol. Paracetamol particles crystallized in the presence of 0.5% w/v PVP 10000 or PVP 50000 produced tablets with improved crushing strength with no tendency to cap even at high ...

The compressive properties of single osteons

The Anatomical Record, 1968
AbstractThe compressive strength of single human osteons has been investigated in specially prepared samples using a microtesting machine equipped with a microwave micrometer. The main conclusions which can be drawn from our results are: (1) In agreement with Gebhardt's theories the ultimate compressive strength is greatest for osteons having ...

Improved compression properties of propyphenazone spherical crystals

International Journal of Pharmaceutics, 2000
Spherical propyphenazone crystals were produced by an agglomeration technique using a three solvents system. After selecting the best propyphenazone solvent (ethyl alcohol), non-solvent (demineralized water) and bridging liquid (isopropyl acetate), several of their ratios were tested by a Sheffé ternary diagram.

Magnetic Properties of Compressed Powdered Iron

Transactions of the American Institute of Electrical Engineers, 1921
This paper describes a new magnetic material which is peculiarly suited to the construction of cores in small inductance coils and transformers such as are used in a telephone plant. The requirements which were to be met involved a core material which should have a constant permeability, a small hysteresis loss, and a small eddy current loss within the

Compressive Properties of Pantyhose Fabric

Textile Research Journal, 2000
To clarify differences in the compressive properties of different kinds of pantyhose fabrics on the market in Japan, cylinder-elongation experiments and wear experiments are conducted, with Zokki, kohhen, sheer, wooly, and conjugate kinds of pantyhose are used as samples.

Compressive Properties of Yttrium Oxide

Journal of the American Ceramic Society, 1996
Compressive properties of polycrystalline yttrium oxide (Y 2 O 3 ) were studied by slow‐strain‐rate experiments (ε= 5.7 × 10 –6 s −1 ) between room temperature and 1600°C ...

Compressive properties of aramid fibres

Polymer, 1997
A four-point bending beam method has been employed in order to study the compressive properties of a number of well-characterized aromatic polyamide (aramid) fibres using a combination of Raman spectroscopy and optical microscopy. Raman spectroscopy has been used to follow the molecular deformation of the aramid fibres in both tension and compression ...

Compressed Hydrogen: Thermophysical Properties

2016
This chapter describes PVT properties of compressed normal hydrogen (75 % orthohydrogen and 25 % parahydrogen) up to 100 MPa and its equation of state (EOS) derived from the measurement data of the Burnett method, along with the measurement methods and correlation of viscosity and thermal conductivity for compressed hydrogen.

Quarkonial frames with compression properties

Calcolo, 2016
Let \(\sum_{k\in Z} \phi (x-k) =1\), \(x\in\mathbb R\), be a partition of unity in \(\mathbb R\), where \(\phi\) is a smooth compactly supported function. Let \(\phi_p (x) = x^p \phi (x)\), \(p\in \mathbb N_0\). The paper deals with the quarks or quarklets \[ \phi_{p,j,k} (x) = 2^{j/2} \phi_p \big( 2^j x-k), \qquad p,j \in \mathbb N_0, \quad k\in ...

Compression properties of lead–bismuth

Journal of Nuclear Materials, 2003
The mechanical properties of a lead–bismuth alloy were studied by compression testing at different temperatures between 20 and 112 °C with strain rates from 10−3 to 10−6/s. The results indicate that the yield strength depends strongly on both temperature and strain rate.
