Climate change and ocean acidification will expose marine organisms to synchronous multiple stressors, with early life stages being potentially most vulnerable to changing environmental conditions. We simultaneously exposed encapsulated molluscan embryos to three abiotic stressors-acidified conditions, elevated temperate, and solar UV radiation in large outdoor water tables in a multifactorial ...

A liquid chromatographic method with comfirmation by capillary electrophoresis was used to determine 12 sulfonylurea herbicides in agricultural water. Analysis of 3 different water matrixes fortified at 2 levels gave good recoveries with adequate sensitivity at the 0.1 ppb level. A portion of the water was acidified with acetic acid and loaded onto an RP-102 solid-phase extraction (SPE) cartrid...

The aim of this study was to investigate and compare Vaccinium myrtillus L. extracts obtained in ultrasonic condition with different water/methanol and water/ethanol extraction mixture acidified with 0.1% HCl. The extracts were analyzed for monomeric anthocyanins contents, total phenolics content and antioxidant activities. The highest anthocyanins content (3888 mg/L), total phenolics content (...

This study was conducted to evaluate the combined effects of blanching and sonication on carrot juice quality. Carrots were blanched at 100 °C for 4 min in normal and acidified water. Juice was extracted and sonicated at 15 °C for 2 min keeping pulse duration 5 s on and 5 s off (70% amplitude level and 20 kHz frequency). No significant effect of blanching and sonication was observed on Brix, pH...

OBJECTIVE To test the effectiveness of 3 topical sprays for treatment of papillomatous digital dermatitis (PDD) in dairy cattle. DESIGN Prospective field trial. ANIMALS 48 lactating cows with PDD randomly assigned to 4 groups of 12 cows each. PROCEDURE For 3 weeks, cows in each group were treated topically with oxytetracycline solution (100 mg/ ml), acidified ionized copper solution, acid...

In Denmark, it was agreed to lower the Salmonella prevalence in pork to 1.2% before the end of 2006. The current control did not seem to be sufficient to attain this goal. Therefore, four alternatives to the existing Danish control strategy for Salmonella in pork were compared in a cost-benefit analysis: (1) hot-water decontamination of all pigs at slaughter, (2) sanitary slaughter of pigs from...

1. Two methods are given for measuring the rate of diffusion of CO(2) in tissue membranes. Methods are also given for the determination of tissue thickness and the absorption coefficient for CO(2) in tissues. 2. The values obtained for the permeability constant (P x 10(4)) at 22 degrees C. for CO(2) in the following tissues are:-frog skin, 3.05; connective tissue (dog), 2.65; smooth muscle (cat...

An improved analytical method which offers rapid, accurate determination and identification of 22 amino acids in a variety of matrices, e.g. baby foods, juices, honey is reported. The amino acids were extracted from the matrixes using acidified water. Simultaneous determination of 22 underivatized amino acids was carried out by a liquid chromatography-mass spectrometry (LC/MS). A narrow-bore co...

Electrowetting and electrocapillarity of liquid metals have a long history, and a recent explosion of renewed interest. Liquid metals have electromagnetic properties and surface tensions (>500 mN/m) that enable new forms of reconfigurable devices. However, the only nontoxic option, gallium alloys, suffer from immediate formation of a semirigid surface oxide. Although acids or electrochemical re...
