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

Direct compression properties of chitin and chitosan

European Journal of Pharmaceutics and Biopharmaceutics, 2008
Deformation and compaction properties of native amino poly-saccharides chitin and chitosan were studied and compared with those obtained with established pharmaceutical direct compression excipients. An instrumented single-punch tablet machine was used for tablet compaction.

Tensile and compressive properties of cancellous bone

Journal of Biomechanics, 1991
The relationship between the mechanical properties of trabecular bone in tension and compression was investigated by non-destructive testing of the same specimens in tension and compression, followed by random allocation to a destructive test in either tension or compression.

Properties of Fused Mannitol in Compressed Tablets

Journal of Pharmaceutical Sciences, 1964
Among the carbohydrates used in compressed tablets, mannitol is the only one which possesses high heat stability. This substance melts at 167°, but does not decompose at temperatures up to 250°. Mannitol, alone and in combination with other carbohydrates, was fused and recrystallized or spray-congealed.

Effect of Physical Properties on Compression Characteristics

Journal of Pharmaceutical Sciences, 1975
The tranmission of force to the die wall was measured by a piezoelectric sensor, and the compression cycles of lactose granules of different shapes were compared. In addition, a nearly spherical fraction of spray-dried lactose was similarly compared with a crystalline sample.

Effect of Compression Speed on Static Compression Properties of Foams

Applied Mechanics and Materials, 2011
Expandable polystyrene and expandable polyethylene foams are frequently used in packaging of products. The study on their cushioning properties is important for the design of the transport package. The effect of compression speed and multiple reloading on the cushioning properties of HDEPS, LDEPS and HDEPE was studied in this paper.

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.

Dynamic Compressive Properties of the Mandibular Condylar Cartilage

Journal of Dental Research, 2006
The mandibular condylar cartilage plays an important role as a stress absorber during function. However, relatively little information is available on its dynamic properties under compression. We hypothesized that these properties are region-specific and depend on loading frequency. To characterize the viscoelastic properties of the condylar cartilage,

Data compression properties of the Hartley transform

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1989
The data compression performance of the Hartley transform on a Markov-1 signal is theoretically compared to that of the Fourier transform. Covariance distribution and residue correlation measurements have been computed for the Hartley, Fourier, and cosine transforms.
