The effect of selected organics on breakpoint chlorination
… organic compound concentrations were varied. The breakpoint curves and total Kjeldahl nitrogen removal efficiencies were determined, and it was demonstrated that each organic has a specific effect on the nature of the breakpoint curve and the nitrogen removal efficiency. It was found that both …

Sequence characterization of the HSA12/22/12 evolutionary breakpoint region on SSC5q21
The HSA12/22/12 evolutionary breakpoint region on SSC5q21 has been sequenced, further localized, and preliminarily characterized. The existence and location of the breakpoint regions were originally determined in the human-porcine comparative map constructed by Meyers and colleagues. Bacterial …

Disk Diffusion Breakpoint Determination Using a Bayesian Nonparametric Variation of the Errors-in-Variables Model
… to various antibiotics. Both tests use breakpoints to classify the pathogen as either susceptible, indeterminant, or resistant to each drug under consideration. While the determination of these drug-specific MIC classification breakpoints is straightforward, determination of comparable …

Breakpoint Chlorination as an Alternate means for Ammoia-Nitrogen removal at a Water Reclamation Plant
… life or human health. The main objective of the breakpoint pilot study was to define optimum breakpoint pilot plant operating conditions which could then be applied to the design of a full scale breakpoint facility and serve as an emergency backup to biological nitrification. A pilot study was …

Daptomycin versus Vancomycin for Empiric Treatment of Methicillin-Resistant S. aureus among Hospitalized Patients: An Institutional Cost-Breakpoint Analysis
… The purpose of this study was to perform a cost-breakpoint analysis comparing daptomycin versus vancomycin as empiric therapy for methicillin-resistant Staphylococcus aureus bacteremia. Methods: Data from a phase III, randomized clinical trial comparing daptomycin to vancomycin was used to build …

Influence of Chlorination and the Distribution System on Mutagens in a Potable Water Supply
… practice from chloramine to chlorination beyond breakpoint at monthly intervals in the summer. We assayed the mutagenicity of the water at weekly intervals and continually through transitions from chloramine to breakpoint and reverse for a period of a year. In general chloramine disinfection …

Genome Rearrangements: Structural Inference and Functional Consequences
… arises of what the biological consequences of breakpoint creation are, rather than just their structural aspects. The question I will ask is whether proximity to the site of a breakpoint event changes the activity of a gene. I propose to investigate this by comparing the distribution of …

Patterns of somatic genome rearrangement in human cancer
… identifying the precise structure of individual breakpoint junctions and separating out complex clusters, the classification scheme empowers detailed exploration of all simple SV properties and signatures. After illustrating the various SV classes and their frequency across cancer types and …

TB-RBP protein : sitting at the crossroads of sex and disease
… protein that binds to specific DNA sequences at breakpoint junctions of chromosomal translocations of lymphoid malignancies. Trax, structural homologue of TB-RBP, has already been shown to interact with the single stranded DNA -/RNA - binding protein TB-RBP. Co-crystallization of TB-RBP/DNA …

Examining the Effect of Interruptions at Different Breakpoints and Frequencies Within a Task
… timing, which had three levels: none, coarse breakpoints, and fine breakpoints. The between-subjects factor was interruption frequency, which had two levels: one and three. According to memory for goals theory (MFG), a task representation at a fine breakpoint is large and thus an interruption …

Comparative genomics of chromosomal rearrangements in malaria mosquitoes
… have more M/SARs than rapidly evolving arms. Breakpoint regions are enriched with repetitive elements. The study revealed that fixed inversions are distributed nonrandomly and breakpoint clustering is common in lineages of A. gambiae and A. stephensi. The parallel association between the …

Proteogenomic Insights Into The Nature Of Chemoresistance In Chronic Myelogenous Leukemia
… of the ABL1 oncogene on chromosome 9, and the breakpoint cluster region gene (BCR) chromosome 22, resulting in the BCR-ABL oncoprotein. BCR-ABL is a constitutively active tyrosine kinase that regulates cell growth and differentiation, leading to uncontrolled cell proliferation by deregulating …

A Daily Diary Examination of Microaggressions and Alcohol Use Among Emerging Adult Bisexual Women: The Role of Alcohol Demand
… several alcohol demand indices (intensity and breakpoint) moderated the association between microaggressions and same-day alcohol use and/or consequences. Specifically, the association between daily microaggressions and same day alcohol consequences was strongest for those with higher …

Using wildlife to biomonitor for antimicrobial resistance in the Scottish environment
… gathered from across the country. Using both breakpoint plate (sample level) and published disk-diffusion (isolate level) methods, we found that resistance to tetracycline was the most prevalent phenotype, while resistance to other antimicrobial classes was generally low or not detectable. …

Modeling and Control of an Active Dihedral Fixed-Wing Unmanned Aircraft
… rejection performance at alternative dihedral breakpoint locations. Simulations were completed using linear parameter-varying (LPV) models, derived from traditional Newtonian aircraft dynamics and associated kinematic equations, to improve the modeling of the nonlinear active dihedral system. …

Conserved recombination patterns across coronavirus subgenera
… that favour the occurrence of recombination breakpoints at specific genomic sites, and selection disfavouring the survival of recombinants within which favourable intra-genome interactions have been disrupted. Here we leverage available whole-genome sequence data for six coronavirus subgenera …

The Reassigned Bandwidth-Enhanced Method of Additive Synthesis
… Partials are defined by a trio of synchronized breakpoint envelopes specifying the time-varying amplitude, center frequency, and noise content. Breakpoints for the partial envelopes are obtained by following ridges on a time-frequency surface computed by the method of reassignment. The …
