Synchrotron-based Fourier-transform infrared (FTIR) microspectroscopy was used to distinguish micropopulations of the codominant algae Microcystis aeruginosa (Cyanophyceae) and Ceratium hirundinella (Dinophyceae) in mixed phytoplankton samples taken from the water column of a stratified eutrophic lake (Rostherne Mere, UK). FTIR spectra of the two algae showed a closely similar sequence of 10 ba...
In this paper, the free vibration analysis of moderately thick rectangular plates axially moving with constant velocity and subjected to uniform in-plane loads is investigated by the spectral finite element method. Two parallel edges of the plate are assumed to be simply supported and the remaining edges have any arbitrary boundary conditions. Using Hamilton’s principle, three equations of moti...
Design of a four channel spectral analyzer to resolve linear combinations of two fluorescent spectra
Advances in molecular probes and fluorescence labeling require sophisticated spectral analysis. For the analysis of spectral data one frequently uses an RGB system (3D color system), dedicated filters for each n basic spectra (nD), or a spectral analyzer (mD, m>n). We present a method for designing spectral filters that optimally resolve all basic spectra as well as all linear combinations of t...
Abstract. The meta-plot is a descriptive visual tool for meta-analysis that provides information on the primary studies in and results of meta-analysis. More precisely, portrays (1) precision statistical power meta-analysis, (2) estimate confidence interval random-effects (3) cumulative yielding robustness check meta-analytic effect size with respect to studies’ precision, (4) evidence publicat...
BACKGROUND Obesity causes changes in cardiac autonomic modulation. OBJECTIVE To investigate the autonomic modulation of eutrophic and obese children by means of indexes of heart rate variability (HRV) obtained through geometric methods. METHODS We analyzed data from 133 children aged 8 to 13, divided into two groups: obese (n = 61) and eutrophic (n = 72) according to body mass index for age...
A "Qi" feeling (a kind of comfortable sense) during and after acupuncture is one of the important determinants to decide quantity (trial number) of acupuncture stimulation. It has been reported that various autonomic responses were evoked when patients felt "Qi" and when acupuncture stimulation had significant effects on EEGs. However, quantitative relationships among acupuncture stimulation, E...
