BACKGROUND Growers have enthusiastically embraced crops genetically modified to express Bacillus thuringiensis (Bt) proteins for insect control because they provide excellent protection from key damaging insect pests around the world. Bt crops also offer superior environmental and health benefits while increasing grower income. However, insect resistance development is an important concern for ...

The purpose of this paper was to evaluate the psychometric properties of a stage-specific self-efficacy scale for physical activity with classical test theory (CTT), confirmatory factor analysis (CFA) and item response modeling (IRM). Women who enrolled in the Women On The Move study completed a 20-item stage-specific self-efficacy scale developed for this study [n=226, 51.1% African-American a...

Cotton production in Australia is a high-value industry with about 90% of fibre produced being exported to Asia, primarily to Indonesia. One aspect of modern cotton production is the heavy usage of insecticide sprays to combat Helicoverpa insects. The high cost of sprays and the public view of the industry regarding its perceived impact on the environment have led to the development of integrat...

We created a deterministic, frequency-based model of the evolution of resistance by corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), to insecticidal traits expressed in crops planted in the heterogeneous landscapes of the southern United States. The model accounts for four generations of selection by insecticidal traits each year. We used the model results to investigate the inf...

This paper reports results of a study of reference models for representing open system environments (infrastructures). One of the issues considered in this paper is how to compare particular reference models known in the literature. We propose a set of features of reference models on which to base such comparisons. We have found that in some cases, due to the ambiguity of definitions, it is dif...

INTRODUCTION Biocompatibility is a desirable feature for root-end filling materials. In this study we aimed to compare a new material called cold ceramic (CC) with intermediate restorative material (IRM) and mineral trioxide aggregate (MTA) using Methyl-tetrazolium bromide (MTT) assay. MATERIALS AND METHODS The materials were tested in fresh and set states: (n=108). The cytotoxicity was compa...

PURPOSE The purpose of this study was to compare the sealing ability of temporary restorative materials at 24 hrs and 1 week. MATERIALS AND METHODS Endodontic access cavities were prepared in 56 extracted lower incisor-teeth and divided into 5 groups (n=10). Standard 5 mm deep access preparations were completed and root canals were prepared to size ISO #30 file. The access cavities were resto...

This paper describes the SCYLLARUS approach to fusing reports from multiple intrusion detection systems (IDSes) to provide an overall approach to intrusion situation awareness. The overall view provided by SCYLLARUS centers around the site’s security goals, aggregating large numbers of individual IDS reports based on their impact The overall view reduces information overload by aggregating mult...
