We characterize local Noetherian domains R   with infinite residue field which admit only finitely many star (prime) operations. We further show that a positive integer n   is equal to the number of star operations on such an ...

It is now apparent that ion beams have a role to play in the machining and polishing of optical components. In this paper we review some of the applications which have been reported so far and also consider future Air Max 90 Essential a...

This article introduces and advances the basic theory of “uniformly primary ideals” for commutative rings, a concept that imposes a certain boundedness condition on the usual notion of “primary ideal”. Characterizations of unifo...

Research library catalogs serve as authoritative sources of access. The increasing practice of including Web sites in the catalog, resources not under the library's control, raises new issues of the catalog's accuracy and reliability. A...

Metastable peak shapes have been derived for a time-of-flight mass spectrometer with a drift space and a circular collector, for fragmentations involving release of internal energy. The dimensions of the initial ion bunch are neglected....

Fish form social aggregations called shoals which often consist of fish with similar morphologies. Experiments using zebrafish pigment variants demonstrate that fish can select shoal mates solely on the basis of their color patterns, an...

We show that defect melting is closely related to SO(3) lattice gauge theory. The phase transition of this system corresponds to a Lindemann melting parameter L≈50γ where γ≈2 is a parameter characterizing the unharmonic content in...

Lauten and Ray pointed out the case of metrics (of correct signature) which do not allow a gravitational field. The incompatibility between the field equations and the high symmetry imposed by the underlying four-parameter group of moti...

Orthodontic treatment for patients with congenitally missing mandibular second premolars can be challenging. Treatment options include keeping the deciduous second molar, extracting the molars and allowing the space to Air Yeezy Canada ...

A. circular-paper Chromatographie method for separating the precious metals Pd+2, Pt+4, lr+4. Rh+3, Ru+3, Os+4 and Au+3, using several solvent mixtures with or without complexing agents, has been studied. Mixtures of microamounts of thr...
