A Nonlinear Least Squares Approach to Time of Death Estimation Via Body Cooling

26.07.2015 | Marianito R. Rodrigo, Journal of Forensic Sciences, 2015

Abstract The problem of time of death (TOD) estimation by body cooling is revisited by proposing a nonlinear least squares approach that takes as input a series of temperature readings only. Using a reformulation of the Marshall–Hoare double exponential formula and a technique for reducing the ...

Inter‐instrumental method transfer of a capillary electrophoretic separation of angiotensin II and five derivatives: Evaluation and update of earlier developed guidelines

22.07.2015 | Bart Cock, Ann Eeckhaut, Johan Stiens, Debby Mangelings, Yvan Vander Heyden, ELECTROPHORESIS, 2015

The increased interest in the separation of peptides, proteins, immunoglobulins and polynucleotides, led to an increased demand for appropriate analytical methodologies and instrumentation. CE is because of its unique separation mechanism and high efficiency, frequently used in the analysis of ...

On EXAFS Debye‐Waller factor and recent advances

22.07.2015 | P. Fornasini, R. Grisenti, Journal of Synchrotron Radiation, 2015

The effects of structural and vibrational disorder on the EXAFS signals are parameterized in terms of the Debye Waller (DW) factor. Here the vibrational contribution is addressed, which for most systems can be singled out by studying the temperature dependence of the EXAFS DW factor, which ...

Influence of the Solvent on the “Casting” Methodology for MWCNT‐Modified Glassy Carbon and Platinum Electrodes

21.07.2015 | Ana Carolina Ângelo Dorim, Herbert Aleixo, Edilton de Souza Barcellos, Leonardo Luiz Okumura, Electroanalysis, 2015

Abstract The choice of electrode material and surface preparation method are usually dictated by the suitability of the electrode to observe an electrochemical parameter, such as heterogeneous electron transfer rate, surface coverage, or redox potential. Thus, the glassy carbon (GC) and ...

Sensors, Vol. 15, Pages 17666-17692: Multiscale Trend Analysis for Pampa Grasslands Using Ground Data and Vegetation Sensor Imagery

21.07.2015 | Scottá, Fernando C.; da Fonseca, Eliana L., Sensors, 2015

This study aimed to evaluate changes in the aboveground net primary productivity (ANPP) of grasslands in the Pampa biome by using experimental plots and changes in the spectral responses of similar vegetation communities obtained by remote sensing and to compare both datasets with meteorological ...
