An Improved Equation for TBS and ADD: Establishing a Reliable Postmortem Interval Framework for Casework and Experimental Studies

21.08.2015 | Colin Moffatt, Tal Simmons, Jeanne Lynch‐Aird, Journal of Forensic Sciences, 2015

Abstract Megyesi etal.'s (J Forensic Sci, 2005, 50, 618) paper was important to forensic anthropology as it introduced a quantitative framework for estimating time since death in human cadavers, based upon physical appearance by way of scoring on a novel scale. However, errors concerning ...

[Report] Localization-delocalization transition in the dynamics of dipolar-coupled nuclear spins

21.08.2015 | Gonzalo A. Álvarez; Dieter Suter; Robin Kaiser, Science , 2015

Nonequilibrium dynamics of many-body systems are important in many scientific fields. Here, we report the experimental observation of a phase transition of the quantum coherent dynamics of a three-dimensional many-spin system with dipolar interactions. Using nuclear magnetic resonance (NMR) on a ...

Induction of a Torpor-Like State by 5’-AMP Does Not Depend on H 2 S Production

21.08.2015 | George J. Dugbartey et al., PLoS ONE, 2015

by George J. Dugbartey, Hjalmar R. Bouma, Arjen M. Strijkstra, Ate S. Boerema, Robert H. Henning Background Therapeutic hypothermia is used to reduce ischemia/reperfusion injury (IRI) during organ transplantation and major surgery, but does not fully prevent organ injury. Interestingly, ...

Long-Term Formaldehyde Emissions from Medium-Density Fiberboard in a Full-Scale Experimental Room: Emission Characteristics and the Effects of Temperature and Humidity

21.08.2015 | Weihui Liang; Shen Yang; Xudong Yang, Environmental Science & Technology, 2015

We studied formaldehyde emissions from the medium-density fiberboard (MDF) in a full-scale experimental room to approximate emissions in actual buildings. Detailed indoor formaldehyde concentrations and temperature and humidity data were obtained for about 29 months. Temperature, relative ...

Influence of Temperature, Relative Humidity, and Soil Properties on the Soil–Air Partitioning of Semivolatile Pesticides: Laboratory Measurements and Predictive Models

21.08.2015 | Cleo L. Davie-Martin; Kimberly J. Hageman; Yu-Ping Chin; Valentin Rougé; Yuki Fujita, Environmental Science & Technology, 2015

Soil–air partition coefficient (Ksoil-air) values are often employed to investigate the fate of organic contaminants in soils; however, these values have not been measured for many compounds of interest, including semivolatile current-use pesticides. Moreover, predictive equations for estimating ...

Effects of defects and element diffusion at coating/substrate interface on damping capacity

20.08.2015 | Xueqin Wang, Yue Ma, Surface and Interface Analysis, 2015

In this work, the effects of the microstructures at the coating/substrate interface and in coating on damping and dynamic modulus by using low pressure plasma spray process and electro‐deposition (ELD) technology to deposit the Ni coating onto the Cu substrate were studied, and also research was ...

Conformations of cationized linear oligosaccharides revealed by FTMS combined with in‐ESI H/D exchange

20.08.2015 | Yury Kostyukevich, Alexey Kononikhin, Igor Popov, Eugene Nikolaev, Journal of Mass Spectrometry, 2015

Previously (Kostyukevich et al. Anal Chem 2014, 86, 2595), we have reported that oligosaccharides anions are produced in the electrospray in two different conformations, which differ by the rate of gas phase hydrogen/deuterium (H/D) exchange reaction. In the present paper, we apply the ...

Extraction of Oligosaccharides from Passion Fruit Peel by Subcritical Water Treatment

20.08.2015 | Khwanjai Klinchongkon, Pramote Khuwijitjaru, Jintana Wiboonsirikul, Shuji Adachi, Journal of Food Process Engineering, 2015

Abstract Passion fruit peel, a major by‐product of the fruit processing, was treated in subcritical water under nonisothermal conditions in batch‐type reactor containing the dried peel and water in the ratio 1:16 (w/w), with maximum temperatures in the range of 100–245C. The effects of the ...

Sensitive determination of methadone in human serum and urine by dispersive liquid–liquid microextraction based on the solidification of a floating organic droplet followed by HPLC–UV

20.08.2015 | S. Taheri, F. Jalali, N. Fattahi, R. Jalili, Gh. Bahrami, Journal of Separation Science, 2015

Dispersive liquid–liquid microextraction based on solidification of floating organic droplet was developed for the extraction of methadone and determination by high‐performance liquid chromatography with UV detection. In this method no microsyringe or fiber is required for supporting the organic ...

Kinetics of tocopherol degradation during the storage of wheat germ oil

20.08.2015 | Micaela Magariño, Carmen M. Mateo, Susana M. Nolasco, The Canadian Journal of Chemical Engineering, 2015

Abstract Tocopherol degradation in wheat germ oil was studied during storage at different temperatures. Two types of wheat germ were used: heat‐treated germ (HT) and raw germ (RG). The oil was extracted (Soxhlet, n‐hexane) and stored at 25 and 47 °C (82 days) and at ‐20 and 5 °C (600 days). ...
