No full text51st Symposium on Extended Atmospheres and Circumstellar Matter in Spectroscopic Binary Systems
No full textThe proposal to organize a Symposium on circumstellar matter and extended atmo spheres in binary systems was first made by the Dominion Astrophysical Observatory to the Executive Committee of the International Astronomical Union in the summer of 1969. It received the support of the presidents of Commissions 29 (Stellar Spectra), 30 (Radial Velocities), 36 (Stellar Atmospheres), and 42 (Photometric Double Stars). Approval in principle was given by the Executive Committee almost immediately, and the Committee further suggested that the Symposium be officially designated the Struve Memorial Symposium. Final approval was given at the time of the 1970 General Assembly of the Union. when the dates of the Symposium were set for August or September, 1972. The Organizing Committee set up consisted of K.O. Wright (Chairman), A.H. Batten, K.-H. B6hm, A.A. Boyarchuk, G. Larsson-Leander, and M. Plavec. In addition, J. Sahade and F.B. Wood acted as advisory members. Local organization was entrusted to a committee consisting of A.H. Batten, E.K. Lee, and C.D. Scarfe. The final dates selected were September 6-12, 1972, and the Sym posium was held at the Island Hall Hotel, Parksville, B.C., on Vancouver Island some 90 miles from Victoria. The Organizing Committee attempted to arrange a Symposium of the type in which no contributed papers would be presented and discussion would range as widely as possible over the field covered by the six invited review papers.Proceedings of IAU Symposium No. 51 (Struve Memorial Symposium) held in Parksville, B.C., Canada, September 6-12, 1972Discussion of Observations of the Flow of Matter Within Binary Systems -- Problems of Gaseous Motion Around Stars -- First Discussion Session -- Second Discussion Session -- Expanding Envelopes of Stars -- Third Discussion Session -- Observations of Stellar Spectra Related to Extended Atmospheres -- Fourth Discussion Session -- The Theory of Extended and Expanding Atmospheres -- Fifth Discussion Session -- Sixth Discussion Session -- Seventh Discussion Session -- Evolutionary Aspects of Circumstellar Matter in Binary Systems -- Eighth Discussion Session -- Ninth Discussion Session -- Tenth Discussion Session -- Summary.The proposal to organize a Symposium on circumstellar matter and extended atmo spheres in binary systems was first made by the Dominion Astrophysical Observatory to the Executive Committee of the International Astronomical Union in the summer of 1969.

The tribological and wear properties of carbon-graphite composites
No full textA range of carbon-graphites with differing properties has been evaluated for wear resistance. These include carbons with a high degree of graphitic order (natural and synthetic graphite), those with little or no such order (pitch bonded cokes, glassy carbons) and impregnated grades. Testing has been carried out using abrasive wear, dry sliding wear, particle erosion, slurry erosion, cavitation erosion and the corresponding wear rates have been related to the bulk properties of the different materials. In all tests; hardness, elastic modulus, porosity and the presence of fillers were found to influence the wear rates of the various grades. Maximum wear rates were consistently observed with the softer, more porous unfilled carbons
Isolation and Aggregation in Economics
No full textIn explaining economic phenomena, economic analysis concentrates on selected influences and fixes the host of other factors under a ceteris paribus clause. This view, which goes back to Alfred Marshall (1842-1924), is developed in the first part of the book.
Aggregation is viewed as a particular application of ceteris paribus analysis - isolation from "structural effects". This leads to an approach, called "closed aggregation", which was introduced by Kenneth May and is also implicit in Keynes' writings but has been neglected more recently. It is argued that macroeconomic models are more stable and more general than the corresponding micro models and that there is no simple analogy between them

Private International Law, Intellectual Property and the Internet
No full textPhDIntellectual property is a territorial right; yet despite this there are a number of
international treaties mandating standards. Historically, this has allowed private
international law and intellectual Property to ignore each other. With the advent
of the Internet this benign neglect has not only ended, but there has been a flood
of new ideas on reconciling the territoriality of intellectual property with the
global nature of the Internet. These new approaches attempt to deal with the
problems associated with international intellectual property litigation - the
uncertainty of which law applies, multiplicity of claims andforum shopping -
each of which increases the cost for both users and proprietors of intellectual
property. This thesis examines these approaches, using wealth maximisation and
economic efficiency, and determines that none of themfits within the constructs of
an efficient solution. However, the proposalfor a single applicable law, enabling
consolidation, is seized upon as efficient. It then follows that the principle of
consensual exchange, enabling private parties to agree which court has
jurisdiction and which law applies (rather than States mandating these matters),
is the efficient solution to the selection problem. This consensual exchange
proposal contains two paradigms - the bilateral and the unilateral - which in
turn are broken down into ten propositions. The bilateral paradigm permits
parties to select not only the jurisdiction to adjudicate the dispute, but also the
universal applicable law. The unilateral Paradigm uses the doctrine actor
sequitur forum rei, with the universal applicable law being selected ex ante by the
proprietor. Finally the propositions are placed within the context of international,
regional and domestic law (of the four target jurisdictions: England and Wales,
the United States, France and Germany) and questions of compatibility are
assessed

You will be contacted as soon as possible. The effective electroweak mixing angle sin 20w is measured from the production and decay of the Z boson in e+e -interactions. The data sample corresponds to an integrated luminosity of 18 pb-l with about 420 000 hadronic and 40 000 leptonic Z decays. The mixing angle sin 20w is determined from several independent measurements: the leptonic and hadronic cross sections, the forward-backward asymmetries of charged leptons and b-quarks, and the z-polarization. The results are found to be in good agreement with each other. The value of sin 20w from a fit to the asymmetries in a model independent method is 0.2321-4-0.0021 and from a global fit to the data in the Standard Model framework is 0.2328+0.0013

The measured inclusive momentum distribution can be reproduced by parton shower Monte Carlo programs and also by an analytical QCD calculation. Comparing our results with low energy e+e -data, we find that QCD describes both the shape and the energy evolution of the r/ spectrum. The comparison of q production rates in quark-and gluon-enriched jet samples does not show statistically significant evidence for more abundant production of q mesons in gluon fragmentation. l Deceased. 2 Supported by the German Forschung und Technologie.

(g = e, #, ~) we observe four events, one e+e -~'7 and three #+ ~-??, with the invariant mass of the photon pairs close to 60 GeV. These events were selected from a data sample collected in the L3 detector corresponding to 950000 produced Z°'s. More data are necessary to ascertain the origin of these events
