    Determining the phase of line objects by measuring their intensity in dark field and bright field illumination

    Full text link
    The in situ phase of a transparent line object can be calculated from measurements of its bright field and dark field intensity. If the sampling aperture is a slit, the background can be subtracted out for increased accuracy. This method can measure phase over a range of approximately 3[deg] to 180[deg]. The theory has been verified by means of an indirect experiment.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33865/1/0000126.pd

    Get PDF
    The Surface Ocean CO2 Atlas (SOCAT) is a synthesis of quality-controlled fCO2 (fugacity of carbon dioxide) values for the global surface oceans and coastal seas with regular updates. Version 3 of SOCAT has 14.7 million fCO2 values from 3646 data sets covering the years 1957 to 2014. This latest version has an additional 4.6 million fCO2 values relative to version 2 and extends the record from 2011 to 2014. Version 3 also significantly increases the data availability for 2005 to 2013. SOCAT has an average of approximately 1.2 million surface water fCO2 values per year for the years 2006 to 2012. Quality and documentation of the data has improved. A new feature is the data set quality control (QC) flag of E for data from alternative sensors and platforms. The accuracy of surface water fCO2 has been defined for all data set QC flags. Automated range checking has been carried out for all data sets during their upload into SOCAT. The upgrade of the interactive Data Set Viewer (previously known as the Cruise Data Viewer) allows better interrogation of the SOCAT data collection and rapid creation of high-quality figures for scientific presentations. Automated data upload has been launched for version 4 and will enable more frequent SOCAT releases in the future. High-profile scientific applications of SOCAT include quantification of the ocean sink for atmospheric carbon dioxide and its long-term variation, detection of ocean acidification, as well as evaluation of coupled-climate and ocean-only biogeochemical models. Users of SOCAT data products are urged to acknowledge the contribution of data providers, as stated in the SOCAT Fair Data Use Statement. This ESSD (Earth System Science Data) “living data” publication documents the methods and data sets used for the assembly of this new version of the SOCAT data collection and compares these with those used for earlier versions of the data collection (Pfeil et al., 2013; Sabine et al., 2013; Bakker et al., 2014).

    Education policy as an act of white supremacy: whiteness, critical race theory and education reform

    Get PDF
    The paper presents an empirical analysis of education policy in England that is informed by recent developments in US critical theory. In particular, I draw on ‘whiteness studies’ and the application of Critical Race Theory (CRT). These perspectives offer a new and radical way of conceptualising the role of racism in education. Although the US literature has paid little or no regard to issues outside North America, I argue that a similar understanding of racism (as a multifaceted, deeply embedded, often taken-for-granted aspect of power relations) lies at the heart of recent attempts to understand institutional racism in the UK. Having set out the conceptual terrain in the first half of the paper, I then apply this approach to recent changes in the English education system to reveal the central role accorded the defence (and extension) of race inequity. Finally, the paper touches on the question of racism and intentionality: although race inequity may not be a planned and deliberate goal of education policy neither is it accidental. The patterning of racial advantage and inequity is structured in domination and its continuation represents a form of tacit intentionality on the part of white powerholders and policy makers. It is in this sense that education policy is an act of white supremacy. Following others in the CRT tradition, therefore, the paper’s analysis concludes that the most dangerous form of ‘white supremacy’ is not the obvious and extreme fascistic posturing of small neonazi groups, but rather the taken-for-granted routine privileging of white interests that goes unremarked in the political mainstream

    Risk perception influences athletic pacing strategy.

    PURPOSE: The objective of this study is to examine risk taking and risk perception associations with perceived exertion, pacing, and performance in athletes. METHODS: Two experiments were conducted in which risk perception was assessed using the domain-specific risk taking (DOSPERT) scale in 20 novice cyclists (experiment 1) and 32 experienced ultramarathon runners (experiment 2). In experiment 1, participants predicted their pace and then performed a 5-km maximum effort cycling time trial on a calibrated Kingcycle mounted bicycle. Split times and perceived exertion were recorded every kilometer. In experiment 2, each participant predicted their split times before running a 100-km ultramarathon. Split times and perceived exertion were recorded at seven checkpoints. In both experiments, higher and lower risk perception groups were created using median split of DOSPERT scores. RESULTS: In experiment 1, pace during the first kilometer was faster among lower risk perceivers compared with higher risk perceivers (t(18) = 2.0, P = 0.03) and faster among higher risk takers compared with lower risk takers (t(18) = 2.2, P = 0.02). Actual pace was slower than predicted pace during the first kilometer in both the higher risk perceivers (t(9) = -4.2, P = 0.001) and lower risk perceivers (t(9) = -1.8, P = 0.049). In experiment 2, pace during the first 36 km was faster among lower risk perceivers compared with higher risk perceivers (t(16) = 2.0, P = 0.03). Irrespective of risk perception group, actual pace was slower than predicted pace during the first 18 km (t(16) = 8.9, P < 0.001) and from 18 to 36 km (t(16) = 4.0, P < 0.001). In both experiments, there was no difference in performance between higher and lower risk perception groups. CONCLUSIONS: Initial pace is associated with an individual's perception of risk, with low perceptions of risk being associated with a faster starting pace. Large differences between predicted and actual pace suggest that the performance template lacks accuracy, perhaps indicating greater reliance on momentary pacing decisions rather than preplanned strategy.This is the author accepted manuscript.

    Zinc chloride has the importance in pharmaceutical/nutraceutical industries for the prevention and treatment of several diseases. The objective of the current study was to investigate the impact of The Trivedi Effect®-Energy of Consciousness Healing Treatment (Biofield Energy Healing Treatment) on physical, structural, and thermal properties of zinc chloride using PXRD, PSD, FT-IR, UV-vis, TGA, and DSC analysis. Zinc chloride was divided into two parts. One part was denoted as the control without any, while the other part was defined as the Trivedi Effect® Treated sample, which received the Trivedi Effect® Treatment remotely from eighteen renowned Biofield Energy Healers. The PXRD analysis revealed that the crystallite size and relative intensities of the PXRD peaks significantly altered in the treated sample compared with the control sample. The crystallite size of treated sample was decreased by 4.19% compared with the control sample. The particle size at d10 and d50 of the Biofield Energy Treated sample decreased by 4.72% and 2.70%, respectively compared with the control sample. But, the particle size of the treated sample increased at d90 by 0.83 compared with the control sample. Consequently, the surface area was increased by 3.22% in the treated sample compared with the control sample. The FT-IR spectroscopic analysis revealed that Zn-Cl stretching in the control and treated sample was at 520 cm-1 and 521 cm-1, respectively. The UV-vis analysis exhibited that the wavelength of the maximum absorbance of the control and treated samples was at 196.4 and 196.2 nm, respectively. The TGA thermograms revealed two steps of the thermal degradation and the weight loss of the treated sample was significantly reduced by 22.54% in the 1st step of degradation compared with the control sample. The DSC analysis showed that the enthalpy of decomposition was significantly increased by 34.9% in the treated sample (89.17 J/g) compared with the control sample (66.10 J/g). Overall, DSC and TGA analysis indicated that the thermal stability of the treated sample was increased compared with the control sample. The current study anticipated that The Trivedi Effect®-Energy of Consciousness Healing Treatment might lead to generate a new polymorphic form of zinc chloride, which would be more soluble, stable, and higher absorption rate compared with the control sample. Hence, the treated zinc chloride could be very useful to design the various forms of nutraceuticals and pharmaceutical formulation which might be providing a better therapeutic response against inflammatory diseases, immunological disorders, aging, stress, cancer, etc. https://www.trivedieffect.com/science/evaluation-of-the-trivedi-effect-energy-of-consciousness-energy-healing-treatment-on-the-physical-spectral-and-thermal-properties-of-zinc-chloride http://www.sciencepublishinggroup.com/journal/paperinfo?journalid=118&doi=10.11648/j.ajls.20170501.1

    Withania somnifera (ashwagandha) root extract is very popular ancient herbal medicine. The objective of the study was to characterize and evaluate the impact of The Trivedi Effect®-Biofield Energy Healing Treatment (Energy of Consciousness) on phytoconstituents present in the ashwagandha root extract using LC-MS. Ashwagandha root extract was divided into two parts. One part was denoted as the control, while the other part was defined as The Trivedi Effect® - Biofield Energy Treated sample, which received Energy of Consciousness Healing Treatment remotely from eighteen renowned Biofield Energy Healers. The LC-MS analysis of the control and treated samples showed a very close retention time (Rt), indicated that the polarity of the phytoconstituents present in the root extract are same. The numbers of peaks observed in the total ion chromatograms were 28 and 29 in the control and treated samples, respectively. The change in the peak height% of the phytoconstituents in the treated sample was altered significantly within the range of -50.91% to 118.12% compared with the control sample. Similarly, the change in the peak area% of most of the phytoconstituents in the treated ashwagandha was significantly altered within the range of -54.95% to 66.95% compared with the control sample. An additional peak was appeared in the treated sample at Rt of 5.72 minutes, which was not found in the control sample. The LC-MS spectra indicated the presence of possible withanolides like -hydroxy-2,3-dihydro-withanolide F, withanolide A, withaferine A, withanone, withanolide D, ixocarpalactone A, withanolide S, thiowithanolide, etc. in both the samples. The peak are percentage (%) was altered in the identified withanolides, but withanolide sulfoxide was increased significantly by 12.44% in the treated sample compared with the control sample. These results indicated that The Trivedi Effect® - Biofield Energy Treatment might have an impact on the intrinsic physicochemical properties of the phytoconstituents present in the ashwagandha root extract. This could be the probable cause of alteration in the peak height, peak area, and appearance of a new peak in the treated sample. As a result, the concentrations of the phytoconstituents altered in the treated sample compared with the control sample. The treated ashwagandha root extract would be helpful for designing better pharmaceutical/nutraceutical formulations which might be providing a better therapeutic response against autoimmune diseases, nervous and sexual disorders, infectious diseases, antiaging, diabetes, cancer, ulcer, immunological disorders, stress, arthritis, etc. Source: https://www.trivedieffect.com/science/liquid-chromatography-mass-spectrometry-lc-ms-analysis-of-withania-somnifera-ashwagandha-root-extract-treated-with-the-energy-of-consciousness http://www.sciencepublishinggroup.com/journal/paperinfo?journalid=398&doi=10.11648/j.ajqcms.20170101.1

    Withania somnifera (Ashwagandha) root extract is very popular ancient herbal medicine. The objective of the study was to characterize and evaluate the impact of The Trivedi Effect® - Energy of Consciousness Healing Treatment (Biofield Energy Healing) on phytoconstituents present in the ashwagandha root extract using GC-MS and NMR. Ashwagandha root extract was divided into two parts. One part was denoted as the control, while the other part was defined as The Trivedi Effect® - Biofield Energy Treated sample, which received The Trivedi Effect® - Energy of Consciousness Healing Treatment remotely from eighteen renowned Biofield Energy Healers. The GC-MS data indicated that the peak height and peak area of The Trivedi Effect® treated sample were found to be altered compared with the control sample. The peak height of the phytoconstituents present in the treated ashwagandha sample was altered significantly in the range of -8.32% to 89.25% compared with the control sample. Similarly, the peak area of the treated sample was altered significantly in the range of - 4.28% to 216.30% compared with the control sample. Overall, the change in the peak area% of the treated sample was significantly altered in the range of -18.29% to 170.18% compared with the control sample. The GC-MS and NMR analysis results identified the presence of withanolides such as glyco-withanolides, alkaloids, and sugars in the root extract in both the sample. The peak area of 2,3,4,5-tetrahydropyridazine (1), methyl ethyl sulfoxide (2), 5,6-dihydro-2-methyl-4(H)pyran-3,4-dione (4), diethoxy-2-methyl-propane (5), 2,3,4,5-tetrahydroxy-tetrahydro-pyran (6), and 3,4-dimethyl-2(3H)-furanone (7) were significantly increased by 170.18%, 58.21%, 7.74%, 139.50%, 23.16%, and 45.63%, respectively in the treated sample compared with the control sample. On the contrary, the peak area% of 2-hydroxy-γ-butyrolactone (3) was decreased by - 14.96% in the treated ashwagandha compared with the control sample. From the results, it can be hypothesized that The Trivedi Effect® - Biofield Energy Treatment might have the impact on the intrinsic physicochemical properties of the phytoconstituents present in the ashwagandha root extract and responsible for the alteration in the relative peak height/area of treated sample compared with the control sample. As a result, the concentrations of the phytoconstituents assumed to be increased in treated sample compared with the control sample. This treated ashwagandha root extract would be helpful for designing better nutraceutical/pharmaceutical formulations which might be providing a better therapeutic response against autoimmune diseases, nervous and sexual disorders, infectious diseases, antiaging, diabetes, cancer, immunological disorders, stress, arthritis, etc. Source: https://www.trivedieffect.com/science/effect-of-the-energy-of-consciousness-the-trivedi-effect-on-withania-somnifera-root-extract-using-gas-chromatography-mass-spectrometry-and-nuclear-magnetic-resonance-spectroscopy http://www.sciencepublishinggroup.com/journal/paperinfo?journalid=320&doi=10.11648/j.jdmp.20170302.1

    Deception studies manipulating centrally acting performance modifiers: a review.

    Get PDF
    Athletes anticipatorily set and continuously adjust pacing strategies before and during events to produce optimal performance. Selfregulation ensures maximal effort is exerted in correspondence with the end point of exercise, while preventing physiological changes that are detrimental and disruptive to homeostatic control. The integration of feedforward and feedback information, together with the proposed brain_s performance modifiers is said to be fundamental to this anticipatory and continuous regulation of exercise. The manipulation of central, regulatory internal and external stimuli has been a key focus within deception research, attempting to influence the self-regulation of exercise and induce improvements in performance. Methods of manipulating performance modifiers such as unknown task end point, deceived duration or intensity feedback, self-belief, or previous experience create a challenge within research, as although they contextualize theoretical propositions, there are few ecological and practical approaches which integrate theory with practice. In addition, the different methods and measures demonstrated in manipulation studies have produced inconsistent results. This review examines and critically evaluates the current methods of how specific centrally controlled performance modifiers have been manipulated, within previous deception studies. From the 31 studies reviewed, 10 reported positive effects on performance, encouraging future investigations to explore the mechanisms responsible for influencing pacing and consequently how deceptive approaches can further facilitate performance. The review acts to discuss the use of expectation manipulation not only to examine which methods of deception are successful in facilitating performance but also to understand further the key components used in the regulation of exercise and performance
