Darstellung doppelbrechender Lipoidtropfen aus dem Serum

Summary (1) Doubly refracting lipoid droplets can be demonstrated in normal and pathological sera by means of alcohol ether extraction. This is not possible with ether extraction alone.(2) These lipoid droplets can be demonstrated only, or almost only, when they are precipitated out of alcohol or ether alcohol

Experimental Observables on Nuclear Liquid Gas Phase Transition

Progress on nuclear liquid gas phase transition （LGPT） or critical behavior has been simply reviewed and some signals of LGPT in heavy ion collisions, especially in NIMROD data, are focused. These signals include the power-law charge distribution, the largest fluctuation of the fragment observables, the nuclear Zipf law, caloric curve and critical exponent analysis etc.     

Réactions cytologiques à l'introduction pulmonaire expérimentale de particules de silicium métalloïdique

Summary By means of intratracheal injection, particles of metalloid silicium about five microns in size are introduced into the lungs of guinea pigs, and the secondary parenchymatous reactions are studied from 10 minutes to 105 days. In the dust cells, the silicium is progressively broken up into very small particles of less than 1 micron in size. The cells do not show degeneration or mummification as the ordinary silica cells (Mavrogordato) do.     

生态社会的召唤

人类发现自身陷入一种境地，在那里似乎没有真正意义的途径使我们从围绕自身的技术型企业中解脱出来，所以我们需要创造一个走向生态纪元的社会。很多社团近期已经热心于进入一个生态社会并在一些领域采取行动，这些领域便是新故事、生物区域主义以及生态特征。     

Rare Earth Doped Polymer Waveguide Materials and Devices

1 Results Rare earth doped waveguide amplifiers and devices have been demonstrated in silica, crystal and other glass hosts. These rare earth doped optical waveguide devices are based on inorganic materials. Many processing steps are required and can lead to long fabrication time and low yield.Polymer materials offer many distinct properties compared to inorganic materials, such as ease of fabrication, low production costs, simple processing steps, and compatibility with micro-fabrication technologies. ...     

La structure de certaines terminaisons nerveuses montre des variations cycliques

Summary All sensory endings of the trigeminal nerve in the dura mater of the rat are formed by a small swelling, from which continues themetaterminal apparatus, fine filaments at the limit of visibility. Periodically the fine granules at the extremity of the filaments swell, whereas the fibrils themselves disappear, leaving a small, round, argentophil mass. Later the filaments reappear, then redeposit their debris, which persists for a time.Thus the metaterminal apparatus manifests cyclic variations, which recall the transitory existence of collaterals observed duringin vivo orin vitro development of nerve fibres.
