The Physical Nature of Polar Broad Absorption Line Quasars

It has been shown based on radio variability arguments that some BALQSOs (broad absorption line quasars) are viewed along the polar axis (o rthogonal to accretion disk) in the recent article of Zhou et a. Thes e arguments are based on the brightness temperature, T(sub b) exceedi ng 10(exp 12) K which leads to the well-known inverse Compton catastr ophe unless the radio jet is relativistic and is viewed along its axi s. In this letter, we expand the Zhou et al sample of polar BALQSOs u sing their techniques applied to SDSS DR5. In the process, we clarify a mistake in their calculation of brightness temperature. The expanded sample of high T(sub b) BALQSOS, has an inordinately large fraction of LoBALQSOs (low ionization BALQSOs). We consider this an important clue to understanding the nature of the polar BALQSOs. This is expec ted in the polar BALQSO analytical/numerical models of Punsly that pr edicted that LoBALQSOs occur when the line of sight is very close to the polar axis, where the outflow density is the highest

Nuclear-Spin Gyroscope Based on an Atomic Co-Magnetometer

An experimental nuclear-spin gyroscope is based on an alkali-metal/noblegas co-magnetometer, which automatically cancels the effects of magnetic fields. Whereas the performances of prior nuclear-spin gyroscopes are limited by sensitivity to magnetic fields, this gyroscope is insensitive to magnetic fields and to other external perturbations. In addition, relative to prior nuclear-spin gyroscopes, this one exhibits greater sensitivity to rotation. There is commercial interest in development of small, highly sensitive gyroscopes. The present experimental device could be a prototype for development of nuclear spin gyroscopes suitable for navigation. In comparison with fiber-optic gyroscopes, these gyroscopes would draw less power and would be smaller, lighter, more sensitive, and less costly

ADULT LEARNING ON THE INTERNET: ENGAGING THE eBAY AUCTION PROCESS

The current revolution of the Information Age is rapidly changing the complexion of many personal and corporate societies. This revolution is changing the methods people use to communicate with each other, research new information, solve problems, and transact business. The purpose of this study was to describe the learning strategies that adults use in learning to engage in the eBay auction process. The study used the following research questions: (a) what are the identified learning strategy preferences of adult learners using eBay, (b) how do the learning strategy preferences of eBay users compare to the norms for ATLAS, and (c) how do eBay users describe their learning processes related to getting started on eBay, participating in eBay activities,communicating on eBay, learning through eBay, and experiencing eBay? This study used a descriptive design along with the information and data gathering advantages of the Internet to collect data about how adults learn using the Internet. An online questionnaire which featured 19 qualitative questions and 11 quantitative Likert scale items was used to determine the perceptions of eBay participants. Assessing The Learning Strategies of AdultS (ATLAS) instrument was imbedded within the online questionnaire to determine the preferred strategies of eBay users. The study involved a representative sample of 380 eBay users which was identified by electronically downloading the e-mail addresses of participants in completed auctions. The sample was stratified by the 13 categories of items listed on eBay. Within each of these categories, high-volume completed auctions were selected in which the final sale price was under $10, between$11 and $100, and over$100

Charged particles in crossed and longitudinal electromagnetic fields and beam guides

We consider a class of electromagnetic fields that contains crossed fields combined with longitudinal electric and magnetic fields. We study the motion of a classical particle (solutions of the Lorentz equations) in such fields. Then, we present an analysis that allows one to decide which fields from the class act as a beam guide for charged particles, and we find some time-independent and time-dependent configurations with beam guiding properties. We demonstrate that the Klein-Gordon and Dirac equations with all the fields from the class can be solved exactly. We study these solutions, which were not known before, and prove that they form complete and orthogonal sets of functions.Comment: 14 page
