Gene flow from single and stacked herbicide-resistant rice (Oryza sativa): modeling occurrence of multiple herbicide-resistant weedy rice.

Background: Provisia™ rice (PV), a non-genetically engineered (GE) quizalofop-resistant rice, will provide growers with an additional option for weed management to use in conjunction with Clearfield rice (CL) production. Modeling compared the impact of stacking resistance traits versus single traits in rice on introgression of the resistance trait to weedy rice (also called red rice). Common weed management practices were applied to 2-, 3- and 4-year crop rotations, and resistant and multiple-resistant weedy rice seeds, seedlings and mature plants were tracked for 15 years.

A collaborative improvement project by an NHS Emergency Department and Scottish Ambulance Paramedics to improve the identification and delivery of sepsis 6.

Early identification of patients with sepsis is key to the delivery of the sepsis 6 bundle including antibiotic therapy within an hour.[1-3] Demand versus capacity challenges in the Emergency Department (ED) led to delays in antibiotic and sepsis 6 delivery. An alerting tool was developed that provided criteria for Scottish Ambulance Service (SAS) Paramedics to alert the ED of potential sepsis patients.

Interaction between saflufenacil and imazethapyr in red rice (Oryza ssp.) and hemp sesbania (Sesbania exaltata) as affected by light intensity.

Background: Saflufenacil is a broadleaf herbicide for preplant burndown and pre-emergence applications in various crops. This study was established to evaluate the absorption and translocation of saflufenacil in hemp sesbania and imazethapyr in red rice as a function of their post-emergence interaction and light intensity.

Results: Imazethapyr plus saflufenacil provided a greater uptake (30%) and translocation (35%) of (14) C-imazethapyr than imazethapyr alone.

Electro-optic technique to study biaxiality of liquid crystals with positive dielectric anisotropy: the case of a bent-core material.

We propose that, for materials having positive dielectric anisotropy, the biaxiality can be clearly verified or excluded by measuring the transmitted light intensity as a function of electric field. If the material is biaxial and is observed in homeotropically aligned cells, the schlieren texture should not disappear (transmitted intensity is not zero) even at very high fields, since the field does not affect the distribution of the second director normal to the main director. On the other hand, if the material is uniaxial the transmitted intensity should decrease with increasing field and a perfect homeotropic texture can be achieved at high fields.

Chirality of lipids makes fluid lamellar phases piezoelectric.

The role of chirality in membrane-forming lipids is not well appreciated at present. Here we demonstrate that the chirality of phospholipids makes fluid lipid bilayers piezoelectric. Thus, chiral lipids would play a central role in the functioning of cell membranes as active mechanotransducers.

Opaque contact lens color choices among women of different ethnic groups.

Purpose: The opaque contact lens (OCL) market is profitable and expanding. This pilot study sought to identify OCL color preferences among women of three ethnic groups, African American (A), white (W), and Hispanic Americans (H).

Methods: Sixty-three brown-eyed female subjects (19 A; 22 W; 22 H), 18 to 35 years of age, with uncorrected near visual accuity of at least 20/50 were recruited.

Metal Emissions from Joule-Heated Vitrification Systems.

Vitrification demonstrations were conducted for surrogates of three inorganic wastewater sludges in a high-temperature, refractory-lined, slurry-fed melter. The total par-ticulate concentrations and melter decontamination factors were determined for selected elements. The decontamination factors were less than 10 for cadmium and lead in all three demonstrations.
