to have it and to rely on it. The price of the book, at £90, makes it inaccessible to them. I don’t know of plans to make the book more easily available in East Africa, but it is vital that this happen. In conclusion, Doyle’s analysis is subtle and rich. The body of research on which it is based is monumental. It is a book we can all rely on in moving towards the next stage in studying the prob...

978 - 0 - 521 - 11309 - 0 - Ellipsoidal Harmonics : Theory and Applications

The sphere, because of its high symmetry, is what might be called a perfect shape. Unfortunately nature is imperfect and many apparently spherical bodies are better represented by an ellipsoid. Consequently in calculations about gravitational potential, for example, spherical harmonics have to be replaced by the much more complex ellipsoidal harmonics. Their theory, which was originated in the ...

بررسی‌های ساختاری و مغناطیسی نانوذرات‌ پروسکایت LaMn1-xCoxO3 (0/1، 75/0، 5/0، 25/0، 0/0 = x)

In this work, the structural and magnetic properties of LaMn1-xCoxO3 (x = 0.00, 0.25, 0.50, 0.75, 1.00) are investigated. The structural characterization of compounds by X-ray powder diffraction is evidence for a rhombohedral structure (R -3c space group). Much less increase of the unit cell volume suggests that Co enters in lattice as Co+2 for x ≤ 0.5 while much more decrease of the unit cell ...

The extended CO J = 1 – 0 emission in NGC 253

The distribution of 12CO(1–0) has been mapped over the spiral galaxy NGC 253 using the Swedish-ESO Submillimetre Telescope (SEST). Emission was found to extend 22.4 arcmin along themajor axis and to be concentrated towards the nucleus with an LSR systemic velocity of 235 km s−1. The CO intensity and velocity distribution suggests three subsystems: a dense, highly-rotating nuclear cloud, a disk ...
