2 v 1 1 4 Ju l 2 00 3 Is the Zee model neutrino mass matrix ruled out ?

A very economic model of generating small neutrino masses is the Zee model. This model has been studied extensively in the literature with most of the studies concentrated on the simplest version of the model where all diagonal entries in the mass matrix are zero. SNO, and KamLAND data disfavor this simple version, but only when one also combines data from atmospheric neutrino data, can one rul...

New Trends and Procedures of Program Assessment for Academic Units

Some consider assessment in terms of a systematic way of gathering and evaluating information within educational system and particularly higher education. Since, the term ‘’assessment’’ refers and relates to administrative processes, this paper has shed light some consideration on how it can benefit the members of department and program. Program assessment ultimately emphasizes on direction for...

An Improved Model to Simulate Mud (Drilling Fluid) Dispersion through Porous Media

An improved model of mud dispersion has been introduced in this work. The advantages of this model consist of a new analytical correlation for dispersivity by using resistivity log data and using a new aspect of capacitance dispersion model. Mathematical formulations were expressed, solved by numerical model taking advantage of actual log and formation data. Achieved results yielded r...
