Volatile organic compounds in seawater
… to seawater and related samples to concentrate volatile organic compounds. The concentrates were subsequently analyzed by glass capillary gas chromatography and combined gas chromatography-mass spectrometry. The compound identities and the spatial and temporal distributions of their …

Making non-volatile memory programmable
Byte-addressable, non-volatile memory (NVM) is emerging as a revolutionary memory technology that provides persistence, near-DRAM performance, and scalable capacity. By using NVM, applications can directly create and manipulate durable data in place without the need for serialization out to SSDs. …

Instabilities of volatile films and drops
We report on instabilities during spreading of volatile liquids, with emphasis on the novel instability observed when isopropyl alcohol (IPA) is deposited on a monocrystalline silicon (Si) wafer. This instability is characterized by emission of drops ahead of the expanding front, with each drop …

New product forecasting in volatile markets
… with prior sales of similar products. But for volatile-share markets, rapid innovation continually alters the shape of available features and performance, leading to products with demand patterns that differ greatly from prior generations and forecasting techniques that rely more on judgment …

Volatile Fatty Acid Production in Ruminants
Volatile fatty acids (VFA) are important products of ruminal fermentation. The VFA are not only the major source of energy to the ruminant animals but also influence methane production in the rumen. Therefore it is important to understand mechanism controlling VFA production and to depict VFA …

The nature and co-behaviour of volatile and non-volatile elements in the sub-continental lithospheric mantle
… mantle represents a critical interface in global volatile cycles because it separates Earth’s convecting mantle from the rigid crust. Nevertheless, the source, abundance and flux of volatiles stored in this reservoir are poorly constrained. In this work, the concentrations of volatiles stored both …

Investigation of Volatile Products from Wood Pyrolysis
… and Slow pyrolysis. We have evaluated the volatile products obtained at different heating rates and the volatile products obtained from sulfuric acid pre-treatment by using gas chromatography- mass spectrometry (GC-MS). We have also performed thermo-gravimetric analysis (TGA) of raw wood …

Biodegradation of Volatile Hydrocarbons in Estuarine Environments
… toluene, isoprene, ethane and propane are volatile organic compounds (VOCs) commonly found in estuarine environments. Benzene and toluene are toxic and carcinogenic at varying concentrations. Isoprene, ethane and propane are emitted from marine environments to the atmosphere where they can …

Interaction of Drops falling into Volatile Liquids
The incidence of explosive melt-coolant interactions (MCIs) has prompted widespread research in an attempt to explain their cause. The conditions under which such explosions may occur is the subject of the present work. Experiments have been performed both in the laboratory and in the field using …

Predictive Modeling of Volatile Organic Compound Measurements
… historical data. Intelligent applications using volatile organic compound (VOC) data have not been as heavily investigated as the aforementioned signals. This thesis takes a first principle approach to analyzing historic VOC data in order to make predictions about future VOC values. The central …

Design for speculation : volatile, temporal, in-transit
The thesis project is a reaction to the alarming rate of building and development depreciation caused by foreign investment in the Middle Eastern city of Dubai. The intervention looks at how architects, developers, and planners can counteract this phenomenon by designing for speculation in order to …

Comprehensive Mapping of Volatile Organic Compounds in Fruits
Volatile organic compounds (VOCs) are the key aroma producers in fruits and sensory quality of fruits is widely determined by qualitative and quantitative composition of VOCs. The aroma of grape is a complex of hundreds of VOCs belonging to different chemical classes like alcohols, esters, acids, …

Non-Volatile Dissolved Organic Iodine in Marine Water
<p>An analytical scheme for the determination of marine DOI has been established. The concentration of DOI is estimated as total iodine (TI) minus total inorganic iodine (TII). The concentration of total iodine is determined as [special characters omitted] after DOI has been oxidized to inorganic …
