We study the population inversion and Q-function of a two-level atom, interacting with single-mode laser light field, in a q-analog harmonic oscillator trap for increasing q. For τ = .003(q = e ) the collapses and revivals of popu∗email:[email protected] 1 lation inversion become well defined facilitating experimental observation but for large τ ∼ 0.1 the time dependence of populatio...

Alginate encapsu lation of an atoxigen ic strain of Aspergillu s ̄ avus was studied in order to optimize encapsu lation of fungal inocula with alginic acid . Steriliza tion by autoclav ing is known to depolymerize sodium alginate . Buffered solution s (pH 5 7± 8) reduced this effect . Autoclaving the alginate solutio n with a ® ller/nutrien t further inhibite d the depolymerization reaction . Au...

Isolation of viral pathogens from clinical and/or animal samples has traditionally relied on either cell cultures or laboratory animal model systems. However, virus viability is notoriously susceptible to adverse conditions that may include inappropriate procedures for sample collection, storage temperature, support media and transportation. Using our recently described ISA method, we have deve...

BACKGROUND Transforming growth factor type-β (TGF-β)/Smad pathway plays an essential role in vascular fibrosis. Reactive oxygen species (ROS) generation also mediates TGF-β signaling-induced vascular fibrosis, suggesting that some sort of interaction exists between Smad and redox pathways. However, the underlying molecular mechanism is largely unknown. This study aims to investigate the influen...

Background: Staphylococcus aureus coloniza-tion for the human nose representing a challenge that requires cope with host defense and competing resident microor-ganisms. Objective: To evaluate risk factors in-fection S. au-reus MRSA among health care workers (HCWs) in Al-Batool teaching hospital maternity children Diyala, Iraq. Patients Methods: A total of 27 swabs were taken from HCWs ma-ternit...

However, what ignored in course these proofs are social, psychological, particular logical aspects resistance. idea a inspired by tendencies philosophy technology, as well other philosophical scientific lines thought that obscure their metaphysical underpi...

In this paper we investigate the dynamic multi cast routing problem for single rate loss networks and brie y discuss the dynamic multicast rout ing algorithm called Least Load Multicast Rout ing LLMR We propose a new multicast routing algorithm called Maximum Mean Number of New Calls Accepted Before Blocking Multicast Routing MCBMR which can more accurately re ect the current and future loading...
