QCD Phenomenology of Charm Production at HERA

We compare different schemes for the treatment of heavy quark production in Deep-Inelastic Scattering (DIS). For fully-integrated quantities such as $F_{2}(x,Q^{2})$, we advocate the use of the General-Massive Variable-Flavor-Number (GM-VFN) scheme; we present some results showing the progress of a Next-to-Leading Order calculation in this scheme. For differential quantities, the Fixed-Flavor-Number (FFN) scheme provides a more appropriate starting point. We present a new calculation of the azimuthal distribution of charm quark production in DIS. All results have been obtained using a Monte Carlo program under development.Comment: 5 pages, Latex/aipproc, 4 figures, presented at DIS 97, Chicago, IL, April 14-18,199

[Review of] Sabine R. Ulibarri. El Condor and Other Stories

This volume continues in the same vein as Governor Glu Glu, but Ulibarri here delves even more deeply into the world of fantasy. Many of the eleven stories in El Condor are like sugar-coated medicine: the sweetness prepares the reader for the lesson which comes in the form of a moral at the end. The Man Who Didn\u27t Eat, for example, is a tale of the scientific creation of a man who is vegetable Frankenstein\u27s monster, with parts taken from many plants. The creature in Ulibarri\u27s story is benevolent; as a result of his superhuman effort to save his neighbors from a plague to which he is immune, he misses his nutritional injection and dies. Ulibarri concludes with his lesson: No one ever knew, neither in the lay world nor in the scientific world, that a living miracle had lived among us. We do not know how to recognize the miracles that surround us. In A Man Who Forgot, the author presents a self-conscious story about a man who remembers only what is good. The moral here is, how beautiful life would be if we could erase from our memory all that is ugly, and remember only the beautiful and the good

[Review of] Sabine R. Ulibarri. El gobernador Glu Glu y otros cuentos (Governor Glu Glu and Other Stories)

Sabine R. Ulibarrí is a prolific and engaging story teller whose works portray the people, the landscape, the folklore, and the tenacious yet evolving way of life in Hispanic northern New Mexico. His previous bilingual collections include Tierra Amarilla (published in Spanish in Ecuador in 1964 and in a dual-language edition in New Mexico in 1971), Mi abuela fumaba puros/My Grandma Smoked Cigars (1977), and Primeros Encuentros/First Encounters (1982.) In these collections, Ulibarri\u27s portrait of the people and the history of his region is an intimate, loving, and somewhat nostalgic one. This latest volume continues to explore the same territory and people, but here Ulibarrí seems more playful, more folkloric at times, and occasionally the pieces seem like fables

Air conditioned suit

An environmentally controlled suit is described consisting of an airtight outergarment attached by an airtight bellows to the wall of a sterile chamber, an undergarment providing for circulation of air near the skin of the wearer, and a circulation system comprised of air supply and distribution to the extremities of the undegarment and central collection and exhaust of air from the midsection of the undergarment. A workman wearing the undergarment and attached circulation system enters the outer garment through a tunnel in the chamber wall and the attached bellows to work in the chamber without any danger of spreading bacteria

[Review of] Nash Candelaria. The Day the Cisco Kid Shot John Wayne

Although Nash Candelaria has published quite a few short stories, it is in the field of the novel where his most outstanding contributions lie. Memories of the Alhambra (1977), Not by the Sword (1982), and Inheritance of Strangers (1985) form an historical trilogy of New Mexico that expresses the conflicts inherent in a society that is largely defined in terms of conquest. The first work takes a disturbing look at a New Mexican who wants to believe he is Spanish, while the other two depict the resiliency of the culture in crisis of the first book

[Review of] Gary Soto. Small Faces

This slim, superb collection is Soto\u27s second foray into the field of prose (Living Up The Street: Narrative Recollections was the 1985 American Book Award winner). The thirty-one vignettes in Small Faces, written in December, 1983, and between June and August, 1984, are imbued with warmth, charm, and nostalgia. They touch subjects such as human nature, human relationships, and love, all from a very personal viewpoint that of the author. During the course of the book, we come to know the poet, his wife and daughter, and his friends. Selections treat the narrator\u27s college days, travel, poetry and philosophy, as well as the mundane episodes of his daily life. The sketches are not presented chronologically, nor are they arranged thematically, so readers can deal with them out of sequence if they so desire. They are short -- from one to four pages -- and because each is an individual unit, one need not set aside a large block of time to read the collection. ( However, the book is so charming that this reviewer read the entire volume in one sitting.

Nuclear Astrophysics

Nuclear physics has a long and productive history of application to astrophysics which continues today. Advances in the accuracy and breadth of astrophysical data and theory drive the need for better experimental and theoretical understanding of the underlying nuclear physics. This paper will review some of the scenarios where nuclear physics plays an important role, including Big Bang Nucleosynthesis, neutrino production by our sun, nucleosynthesis in novae, the creation of elements heavier than iron, and neutron stars. Big-bang nucleosynthesis is concerned with the formation of elements with A <= 7 in the early Universe; the primary nuclear physics inputs required are few-nucleon reaction cross sections. The nucleosynthesis of heavier elements involves a variety of proton-, alpha-, neutron-, and photon-induced reactions, coupled with radioactive decay. The advent of radioactive ion beam facilities has opened an important new avenue for studying these processes, as many involve radioactive species. Nuclear physics also plays an important role in neutron stars: both the nuclear equation of state and cooling processes involving neutrino emission play a very important role. Recent developments and also the interplay between nuclear physics and astrophysics will be highlighted.Comment: To be published in the Proceedings of 19th Lake Louise Winter Institute (15-21 February 2004). 9 pages, 3 figure

[Review of] Beatriz Rivera. African Passions and Other Stories

In recent years there have been many novels, collections of short stories, and editions of poetry published by Mexican-Americans, but the works by Cuban-Americans have not been as plentiful. African Passions, the first published collection by Beatriz Rivera, is a promising but not altogether satisfying contribution to the corpus of Cuban-American writing. It is sometimes brilliant and imaginative, sometimes not very inspiring, with eight stories (several of which are interrelated) ranging from the humorous and well-conceived to the rather tedious
