The role of inflammation in delayed muscle soreness (DMS) and the effects of indomethacin on DMS and perceived exertion
… group (C), to re-examine the concept that DMS represents an acute inflammatory response. Subjects were assigned to receive either Indocin (Id; 100 mg per day) for 2 days prior to the treatment and a placebo (P) for 2 days after (Id-P); or the reverse combination (P-Id); or Id for- 4 days …

The Impact of the Defense Message System (DMS) on the United States Surface Navy
… examines the planned implementation of the DMS and its impact on the Department of Defense DoD, the Navy and, specifically, naval surface ships. The DMS phased planning will be evaluated, with a concentration on several key technological developments that will support the modernization of …

Production of Dimethyl Sulphide (DMS) by Scleractinian Coral during Aerial Exposure – Effect of Temperature and Light
In this thesis I investigated how rates of DMS production in three Scleractinian corals were affected by both aerial exposure and different light and temperature regimes. Coral specimens were acclimated over a 1 month period prior to data collection. Gas samples were collected from corals both …

Marine microbial production of dimethylsulfide from dissolved dimethylsulfoniopropionate
Dimethylsulfide (DMS) plays a central role in the transfer of sulfur from the ocean to the atmosphere, and ultimately to land. The most abundant volatile organosulfur compound in seawater, DMS is believed to account for the bulk of the sea-to-air biogenic sulfur flux. DMS has also been implicated …

Mechanistic, sensitivity, and uncertainty studies of the atmospheric oxidation of dimethylsulfide
… and reactivity of dimethylsulfide (CH3SCH3, DMS) make it an integral component in the atmospheric sulfur cycle. DMS is rapidly oxidized in the atmosphere by a complex gas-phase mechanism involving many species and reactions. The resulting oxidized sulfur-bearing products are hygroscopic and …

Destination management systems : towards a holistic effectiveness evaluation
… understanding of destination management system (DMS) effectiveness and its evaluation. Upon review of the literature, it was established that DMS effectiveness and its evaluation has not yet been researched adequately. Informed by an interpretive approach, this study contributes to research …

Effects of a Driver Monitoring System on Driver Trust, Satisfaction, and Performance with an Automated Driving System
… were affected by a Driver Monitoring System (DMS), which provided alerts to the driver when he or she became inattentive to the driving environment. There were two specific research questions. The first was centered on addressing how drivers' trust and satisfaction with an Automated Driving …

Investigating the controls on surface ocean dimethyl sulphide concentrations at regional to global scales
… biogenic sulphur compound, dimethyl sulphide (DMS) at regional to global scales. The primary focus is upon the role of solar irradiance and metrics of biological activity in modulating DMS concentrations using bivariate and multivariate statistical techniques in conjunction with three different …

The relative contribution of free radicals to the oxidation chain of Dimethylsulphide in the marine boundary layer
… photochemische Senke von Dimethylsulfid(DMS) in der reinen marinen Atmosphäre und beherrschen den globalen Abbau von DMS. In Gebieten mit starker Luftverschmutzung kann das Oxidationsvermögen von nächtlich gebildeten Nitratradikalen (NO3) jenes von OH am Tage bei Weitem übertreffen. …

Development of an automatic system to monitor the performance of a dense medium (mineral) separation process
Dense Medium Separation (DMS) is a process used extensively in the minerals processing industry to separate dense from less dense material in a dense fluid. It may be considered to be a simple “sink-float” separation process. DMS is used on a large scale in South African coal, iron ore and diamond …

Development, uncertainty quantification, and reduction of a dimethyl sulfide oxidation mechanism
Dimethyl sulfide (DMS), arising from phytoplankton, is the largest natural source of sulfur in the atmosphere. The oxidation products of DMS, such as methanesulfonic acid and sulfuric acid, can contribute to cloud condensation nuclei. Studying the oxidation mechanism of DMS will help improve our …

Prozessierung und elektrische Charakterisierung von ZnSe Heterostrukturen in verschiedenen Messgeometrien zum eindeutigen Nachweis der elektrischen Spininjektion
… die in der Vergangenheit an ZnSe-basierenden DMS/NMS/DMS Multischichtsystemem durchgeführt wurden, zeigten eine 25-prozentige Erhöhung des Widerstandes beim Übergang vom unpolarisierten in den polarisierten Zustand des DMS. Dieser Magnetowiderstandseffekt wurde durch elektrische Spininjektion …

The reaction of bis(thioether) complexes of (octaethylporphyrinato)ruthenium(II) with dioxygen, and the catalyzed O₂-oxidation of thioethers
… a CD₂Cl₂ solution containing ≈ 20 mM of Ru(OEP)(dms)₂ (dms ≋ dimethylsulfide) and ≈ 12 mM PhCOOH, exposed to 1 atm of O₂ at room temperature, ¹H-nmr analysis shows that most of the Ru(OEP)(dms)₂ has oxidized to Ru(OEP)(dmso)₂ over a period of 35h. Three detected intermediates are identified as …

The effects of elevated CO2 and ocean acidification on the production of marine biogenic trace gases
… pH and changes in volatile dimethylsulphide (DMS) and halocarbon concentrations, through 70,000 litre, high pCO2 mesocosm experiments and laboratory culture studies. DMS is a climatically important trace gas produced by marine algae: it transfers sulphur into the atmosphere and is a major …

DEVELOPMENT OF DISCOURSE MARKERS IN KOREAN AND ENGLISH MONOLINGUAL CHILDREN AND IN KOREAN-ENGLISH BILINGUAL CHILDREN
… study explores the use of discourse markers (DMs) in talk-in-interaction of Korean-English bilingual children and their monolingual peers in two languages. The corpus-driven analysis proposes a core meaning of the two DMs as signaling contextual divergence in two monolingual groups. Both …
