Factors Associated with HPV Knowledge Among Professionals in the City of Francisco Beltrão, Brazil.

The human papilloma virus (HPV) is the most common sexually transmitted infection, affecting nearly 50% of the world population. HPV can lead to tissue damage and is associated with many types of cancers. Healthcare professionals' knowledge regarding HPV infection are essential in assuring favorable outcomes for those exposed to HPV, either in prevention or in intervention efforts.

Multiconfigurational quantum propagation with trajectory-guided generalized coherent states.

A generalized version of the coupled coherent states method for coherent states of arbitrary Lie groups is developed. In contrast to the original formulation, which is restricted to frozen-Gaussian basis sets, the extended method is suitable for propagating quantum states of systems featuring diversified physical properties, such as spin degrees of freedom or particle indistinguishability. The approach is illustrated with simple models for interacting bosons trapped in double- and triple-well potentials, most adequately described in terms of SU(2) and SU(3) bosonic coherent states, respectively.

A two-layer approach to the coupled coherent states method.

In this paper, a two-layer scheme is outlined for the coupled coherent states (CCS) method, dubbed two-layer CCS (2L-CCS). The theoretical framework is motivated by that of the multiconfigurational Ehrenfest method, where different dynamical descriptions are used for different subsystems of a quantum mechanical system. This leads to a flexible representation of the wavefunction, making the method particularly suited to the study of composite systems.

Differential retention of PCB congeners in cockroaches Blattella germanica.

Organisms differ widely in their ability to metabolize and eliminate polychlorinated biphenyls (PCBs). We evaluated the retention of PCB congeners, reference standard mixture, experimentally injected into cockroach Blattella germanica, in relation to sex and time, and its elimination through the feces, exuviae and oothecae. The nymphs that died prematurely had a higher average PCB retention than those with a longer lifetime, 88% of the injected dose for those that died within 1 to 10 days, and 76% for those within 11-20 days.
