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.

Physics of solids under strong compression [PDF]

Reports on Progress in Physics, 1996
Progress in high pressure physics is reviewed with special emphasis on recent developments in experimental techniques, pressure calibration, equations of state for simple substances and structural systematics of the elements. Short sections are also devoted to hydrogen under strong compression and general questions concerning new electronic ground ...

The physics of tablet compression. VII. Determination of energy expenditure in the tablet compression process

Journal of the American Pharmaceutical Association (Scientific ed.), 1955
Abstract Energy expended in the tablet compression process was calculated by consideration of the magnitude and relation between the several compression variables. In the compression of about 0.4 Gm. of unlubricated sulfathiazole granulation to a maximum force of 1200 Kg, on the lower punch with flat‐faced 3/8‐inch punches, about 8.6 calories were ...

Physics of Tablet Compression XIII

Journal of Pharmaceutical Sciences, 1963
A method for determining the pressure transmitted to the die wall during tablet compression is described. Basically, the method involves strain-gauge measurement of die expansion and the relation of this to the transmitted pressure. The pressure transmitting behavior of a number of compounds, both organic and inorganic, have been studied; some ...

Physical Analysis of the Compression of Filament Assemblies

Textile Research Journal, 2002
This paper presents experimental results on filament assembly compression showing the influence of porosity on the compacting pressure necessary for attaining the desired packing density. At the same time, a physical description of the compacting phenomenon is given.

Advancing test compression to the physical dimension

2017 IEEE International Test Conference (ITC), 2017
Test Compression ratios are currently stalled at 100–200X. A new 2-dimensional physically-aware sequential Compressor-Decompressor design addresses the severe wiring congestion as well as the test coverage droop and pattern spike at the highest compression ratios. Results on some commonly used industrial designs shows a 2X reduction in routing overhead

Change of genetic expression by physical compression forces

Cell Biology International Reports, 1990
Despite intense investigation of transmembrane signalling mediated by lymphocyte surface molecules, the subcellular mechanisms responsible for these phenomena remain poorly understood (Kishimoto, T. et al., 1983). In the present study, an answer for the mechanism is demonstrated by using human B blastoid cell line (CESS) which has IgG and Interleukin 6

Physical characteristics of compressed cotton stalks

Biosystems Engineering, 2008
A study was carried out to evaluate the physical characteristics of chopped cotton stalks and to establish correlations of physical characteristics with moisture content and compression pressure. Chopped cotton stalks having a moisture content varying from 8.5% to 21.45% (w.b.) were densified into square blocks (80 mm by 80 mm) at compression pressures

The Physics of Tablet Compression. I. A Preliminary Report†

Journal of the American Pharmaceutical Association (Scientific ed.), 1952
A preliminary report surveying a series of basic studies on compressed tablets is presented. For procurement of data toward elucidation of tablet structure and behavior, tentative methods for determining (a)tablet density, (b) bulk density of the mixed ingredients, (c) porosity and pore size of tablets, and (d) the compressional force and compressional
