As one of the nearest examples of an active galaxy, NGC5128 (Centaurus A) has been studied in detail over a wide range of wavelengths. The nucleus of the galaxy is seen clearly in the X-ray, radio and infrared, but is ...

The K-band polarization has been measured in the region extending 30 arcsec to the SW of L 1551 IRS 5. The degree of polarization is exceptionally high, reaching ≡67 per cent. The large polarizations and the azimuthal ...

The three-dimensional structure of trypsin-modified EF-Tu polymers was analyzed to a resolution of 30 Å with electron image reconstruction techniques after negative staining. In a 70% saturated ammonium sulfate solution ...

A comparison was made of the number of antenatal visits made by 96 women receiving integrated antenatal care in an experimental community clinic with 100 women receiving traditional shared care from two control practices. ...

Saul Kripke's recent discussion of Wittgenstein's later philosophy presents a powerful sceptical paradox. The conclusion of it is that no facts about an individual considered on his own determine what he means by his words. ...

The recently demonstrated technique of laser guiding has been used to propagate successfully a 10-kA relativistic electron beam 95 m through the Advanced Test Accelerator and postaccelerator beamline. The maximum transverse ...

This paper describes an easily constructed and inexpensive demandfeeder. The feeder is driven by an AC synchronous motor and gearbox and is suitable for microcomputer control. It will operate with inexpensive commercially ...

The polarization of the broadband continuum at K has been mapped in the core of the OMC-1 with high spatial resolution, and with lower resolution in a more extensive surrounding area. In addition, the first detailed ...
