DESIGNATION AND PSYCHOMETRIC PROPERTIES OF THE SHORT FORM POSTPARTUM QUALITY OF LIFE QUESTIONNAIRE (SF-PQOL): AN APPLICATION OF MULTIDIMENSIONAL ITEM RESPONSE THEORY AND GENETIC ALGORITHM

Background: Utilizing multidimensional item response theory (MIRT) and genetic algorithm(GA) we aimed to design and test the psychometric properties of the short form Postpartum Quality of Life Questionnaire (PQOL).Methods: In this methodological study, 500 women aged 18 to 42 were enrolled through multistage random sampling scheme in Tabriz, Iran.

Enveloped viruses, such as HIV, Ebola and Influenza, are among the most deadly known viruses.Cellular membrane penetration of enveloped viruses is a critical step in the cascade simply southern cat shirt of events that lead to entry into the host cell.Conventional ensemble fusion assays rely on collective responses to membrane fusion events, and do

Abstract Preferential attachment is an important mechanism in the structural evolution of complex networks.However, though resources on a network propagate and have an effect beyond a direct relationship, growth by preferential attachment based on indirectly propagated resources has not been systematically investigated.Here, we propose a mathematic

Well-crystallized and hexagonal wurtzite ZnO was synthesized with nanocellulose using a facile hydrothermal method.Many highly active (001) facets were retained in the obtained ZnO nanocrystals, presumably due to interaction between the polar jmannino.com facet of ZnO and the nanocellulose.Given its effective surface area, the synthesized ZnO exhib

There is a growing pressure on the available freshwater resources in South Africa and many other countries around the world.This has led to a large scale of interest in the application of water reclamation and reuse of wastewater as alternative water supply sources.This is becoming critical to sustain development and economic growth in the southern
