Caution on the use of NBS 30 biotite for hydrogen-isotope measurements with on-line high-temperature conversion systems.

Rapid communications in mass spectrometry : RCM

Qi H, Coplen TB, Olack GA, Vennemann TW.
PMID: 25132299
Rapid Commun Mass Spectrom. 2014 Sep 30;28(18):1987-94. doi: 10.1002/rcm.6983.

RATIONALE: The supply of NBS 30 biotite is nearly exhausted. During measurements of NBS 30 and potential replacements, reproducible δ(2)HVSMOW-SLAP values could not be obtained by three laboratories using high-temperature conversion (HTC) systems. The cause of this issue has...

Biodiversity and conservation

Karsten U, Holzinger A.
PMID: 24954980
Biodivers Conserv. 2014;23:1845-1858. doi: 10.1007/s10531-014-0653-2. Epub 2014 Mar 02.

Green algae are major components of biological soil crusts in alpine habitats. Together with cyanobacteria, fungi and lichens, green algae form a pioneer community important for the organisms that will succeed them. In their high altitudinal habitat these algae...

Model Earth Syst Environ. 2015 Dec 01;1(4):32. doi: 10.1007/s40808-015-0041-2.

In this article, the setup and the application of an empirical model, based on Newton's law of cooling, capable to predict daily mean soil temperature (

Long-term results after endoscopic drainage of pancreatic pseudocysts: A single-center experience.

Pancreatology : official journal of the International Association of Pancreatology (IAP) ... [et al.]

Rückert F, Lietzmann A, Wilhelm TJ, Sold M, Kähler G, Schneider A.
PMID: 28606430
Pancreatology. 2017 Jul - Aug;17(4):555-560. doi: 10.1016/j.pan.2017.06.002. Epub 2017 Jun 03.

BACKGROUND: Pancreatic pseudocysts (PPC) are collections of fluid encapsulated within a well-defined inflammatory wall that develop during pancreatic inflammation. Internal drainage represents the standard of care in lesions that persist and lead to symptoms and complications. Only limited data...

Suspect screening of micropollutants and their transformation products in advanced wastewater treatment.

The Science of the total environment

Deeb AA, Stephan S, Schmitz OJ, Schmidt TC.
PMID: 28605842
Sci Total Environ. 2017 Dec 01;601:1247-1253. doi: 10.1016/j.scitotenv.2017.05.271. Epub 2017 Jun 09.

Transformation products (TPs) of organic micropollutants are still rarely considered in monitoring of wastewater and aquatic environments. For example, occurrence data of ozonated TPs in full-scale wastewater systems is largely lacking. In this study, the efficiency of a suspect...

Transformation efficiency and formation of transformation products during photochemical degradation of TCE and PCE at micromolar concentrations.

Journal of environmental health science & engineering

Dobaradaran S, Lutze H, Mahvi AH, Schmidt TC.
PMID: 24401763
J Environ Health Sci Eng. 2014 Jan 08;12(1):16. doi: 10.1186/2052-336X-12-16.

BACKGROUND: Trichloroethene and tetrachloroethene are the most common pollutants in groundwater and two of the priority pollutants listed by the U.S. Environmental Protection Agency. In previous studies on TCE and PCE photolysis and photochemical degradation, concentration ranges exceeding environmental...

Glucagonoma-induced acute heart failure.

Galaxy clusters are the most massive constituents of the large-scale structure of the universe. Although the hot thermal gas that pervades galaxy clusters is relatively well understood through observations with x-ray satellites, our understanding of the nonthermal part of...

Mechanisms of Practice-Related Reductions of Dual-Task Interference with Simple Tasks: Data and Theory.

Advances in cognitive psychology

In dual-task situations, interference between two simultaneous tasks impairs performance. With practice, however, this impairment can be reduced. To identify mechanisms leading to a practice-related improvement in sensorimotor dual tasks, the present review applied the following general hypothesis: Sources...
