Kinetics of submicron oleic acid aerosols with ozone: A novel aerosol mass spectrometric technique

[1] The reaction kinetics of submicron oleic (9-octadecanoic (Z)-) acid aerosols with ozone was studied using a novel aerosol mass spectrometric technique. In the apparatus a flow of size-selected aerosols is introduced into a flow reactor where the particles are exposed to a known density of ozone for a controlled period of time. The aerosol flow is then directed into an aerosol mass spectrome...

Quantitation of Fluoroacetic Acid and Fluoroacetamide with Mass Spectrometric Detection

Fluoroacetate (Compound 1080) and fluoroacetamide are strong metabolic poisons commonly used as rodenticides and predacides.1,2 Fluoroacetic acid is also an intermediate metabolite of many compounds, such as anticancer drugs 5-fluorouracil and fluoroethyl nitrosourea. Fluoroacetate is cheap and simple to synthesize, tasteless, and has a high solubility in water. Due to their high level of toxic...

Absorption of carbon dioxide during laparoscopy in children measured using a novel mass spectrometric technique.

BACKGROUND Carbon dioxide (CO(2)) is absorbed during pneumoperitoneum and may cause adverse haemodynamic effects. The aim of this study was to measure the elimination of exogenous CO(2) during laparoscopy in children. METHODS Ten children [27.6 (56.5) months; mean (SD)] undergoing laparoscopic and nine [24.5 (17.3) months] undergoing open surgery were studied. Breath samples were collected at...

Tuned Mass Dampers for Earthquake Vibrations of High-rise Buildings using Bee Colony Optimization Technique

This paper investigates the application of Artificial Bee Colony (ABC) method for the optimization of Tuned Mass Dampers (TMDs) employed for high-rise structures including Soil Structure Interaction (SSI). The model is a 40-story building, and Newmark method is utilized for the structure response to Bam earthquake data. The objective is to decrease both maximum displacement and accelerati...
