Abstract:
The properties of solar acoustic oscillations are known to vary with the solar cycle. With 20 years of continuous observations by GONG, we are now in the position to carry out a comparison of the variation of the p mode parameters between the last two solar cycles. We present results of our analyses of the widths, amplitudes, areas (width $\times$ amplitude), and background amplitudes of solar p modes, as well as the corresponding physical quantities for modes of harmonic degree $10\leq l \leq 150$ of the global solar oscillations. We investigate the variation of these parameters for different ranges of mode frequency and harmonic degree. The fractional change in mode widths is largest for modes in the frequency range 2400-3300 $\mu$Hz, regardless of harmonic degree, with an amplitude of $\sim 10\%$ between solar minimum and maximum. The fractional change in mode amplitude exhibits a peak-to-peak amplitude of $\sim 30\%$ over solar cycle 23. Also, we find hysteresis in mode amplitudes over cycle 23 for some combinations of mode frequencies and harmonic degree. The physical quantities which correspond to the mode parameters (mean square velocity power, total mode energy, mode energy supply rate) are investigated as a function of time for different ranges of harmonic degree. We find that the mode energy supply rate decreased by $\sim 20\%$ over the last 20 years.

Abstract:
From 1919 to 2002, Paris-Meudon Observatory published synoptic maps of the Solar activity. Together with maps, tables were provided, containing some information concerning at least filaments. The board of Paris Observatory funded a data capture program concerning the 680 000 basic informations available in those tables. On the other hand, in the frame of the FP7 European project HELIO, a Heliophysics Feature Catalogue (HFC) has been developed, which contains also filaments data from 1996 up to now. We now pool all these data in order to give access to a filaments database for nearly a century of observations. This allows to make statistical studies of those Solar features, and try to correlate them with other information such as sunspot number, ... . We present here the first results of such studies, showing long-term global behavior of filaments.

Barban, C & Mosser, B
Abstract:
The Kepler space mission has observed many solar-like pulsators, and helped to decipher their main characteristics (e.g: mass, radius, rotation). Most of the achievements recently obtained in that domain consist of the analysis of the mode frequency positions. However, unique information on non-adiabatic physics derives from the height and width of the modes. In this study, we aim to measure the mode widths in thousands of Kepler red giants and to analyze their behavior in function of stellar parameters as well as seismic parameters. The results unveil a clear dependence on mass and stellar evolution for the star mode width, thus their mode damping.

Abstract:
Asteroseismology — the study of stellar interiors through their global oscillations — has been revolutionised with the launch of dedicated space missions. The CoRoT and Kepler satellites perform(ed) high precision photometric measurements of tens to hundreds of thousands of stars with the aim to detect both stellar oscillations and planets. In this talk I will present the main breakthroughs with respect to solar-like oscillators — stars that have convective outer layers in which oscillations are stochastically excited.

Abstract:
In this talk, we would like to analyze the configuration and evolution of magnetic fields and the corresponding relationship with the magnetic non-potentiality and helicity of active regions by means of observations of solar vector magnetograms. We present the magnetic helicity distribution and the change with the solar cycles based on the statistical analysis of the magnetic field in solar active regions. We also discuss some questions on the solar vector magnetic field and helicity from the solar observations.

Abstract:
In 1908, American astronomer George E. Hale discovered the presence of the magnetic field in sunspots, and in 1917, a systematic observations of sunspot magnetic fields begun at Mount Wilson Observatory (MWO). In early 1950s, the first photoelectric magnetograph was developed by H. W. Babcock, and soon after, a number of magnetographs was developed in several countries around the globe. In mid-1960s, regular observations of full disk longitudinal magnetograms started at MWO, and in early 1970s, the full disk magnetograph observations begun at the National Solar Observatory at Kitt Peak. This dataset continues using Vector SpectroMagnetograph (VSM) on Synoptic Optical Long-term Investigations of the Sun (SOLIS) platform. Since 2010, the full disk magnetogams are observed by Helioseismic and Magnetic Imager (HMI) on board of Solar Dynamics Observatory (SDO). In this talk, I briefly review history and methods of observations of magnetic fields on the Sun, and discuss major discoveries in long-term studies of the photospheric magnetic fields.

Abstract:
This workshop focuses on the topics of connecting Internet of Services and Things as event sources of a global “smart dust” with the management of business processes and the Future and Emerging Technologies as addressed by the European FET-F 2020 and Beyond Initiative. Such FET challenges are not longer limited to business processes, but focus on new ideas in order to connect processes on the basis of CEP with disciplines of Cell Biology, Epigenetics, Brain Research, Robotics, Emergency Management, SocioGeonomics, Bio- and Quantum Computing – summarized under the concept of U-CEP. This workshop extends edBPM as actually "commodity" from the perspective of the scientific State of the Art, although there are no real adopters so far and we are far from standards. This workshop extends edBPM as ed(B)PM (not all processes must be “business” processes) to U-CEP (new application domains, new services from the "Universe"). In continuation with the edBPM workshops at the 1st ServiceWave 2008 in Madrid and the 2nd ServiceWave 2009 in Stockholm, this 3rd workshop is a thematical enhancement considering the grand challenges defined by Future Internet Initiative and FET-F. The workshop positions U-CEP as an appropriate umbrella for new medium-term Future Internet- and long-term FET-F technologies, products and ideas.

Abstract:
1,2,3-Trimethoxybenzene (TMB) is one of the most versatile chemical used for the synthesis of several pharmaceuticals, dyes, polymers, organic compounds, etc. The stable isotope ratio analysis has increased attention day-by-days in several fields such as agricultural, food authenticity, biochemistry, medical research, etc. The current study was aimed to evaluate the effect of the biofield energy treatment on the isotopic abundance ratios of 13C/12C or 2H/1H or 17O/16O (PM+1/PM) and 18O/16O (PM+2/PM) in TMB using Gas chromatography - mass spectrometry (GC-MS) technique. TMB was divided into two parts - one part was denoted as control and another part was referred as biofield energy treated sample that was received through Mr. Trivediꞌs unique biofield energy (The Trivedi Effect®). The GC-MS of the biofield treated TMB was characterized at different time intervals considered as T1, T2, T3, and T4 to examine the impact of the biofield energy treatment on isotopic abundance ratio with respect to the time. The GC-MS spectra of the both control and biofield treated TMB exhibited the presence of molecular ion peak [M+] at m/z 168 (calculated 168.08 for C9H12O3) along with similar pattern of fragmentation. The relative peak intensities of the fragmented ions in the biofield treated TMB, particularly at T2 and T3 was altered from the control sample. The isotopic abundance ratio analysis in the biofield treated TMB exhibited that the isotopic abundance ratio of PM+1/PM in the biofield treated TMB at T2 and T3 was significantly enhanced by 128.13 and 117.99%, respectively with respect to the control sample. Consequently, the percentage change in isotopic abundance ratio of PM+2/PM was significantly increased in the biofield treated TMB at T2 and T3 by 125.93 and 116.67%, respectively as compared with the control TMB. The isotopic abundance ratios (PM+1/PM and PM+2/PM) in the biofield treated TMB at T1 and T4 was altered with respect to the control TMB. In summary, 13C, 2H, and 17O contributions from (C9H12O3)+ to m/z 169 and 18O contribution from (C9H12O3)+ to m/z 170 for the biofield treated TMB, particularly at T2 and T3 were significantly improved and biofield treated TMB might exhibit changed isotope effects as compared to the control sample. The biofield treated TMB might assist to develop new chemicals and pharmaceuticals through using its kinetic isotope effects like understanding the reaction mechanism, the enzymatic transition state and all aspects of enzyme mechanisms.

Abstract:
1-Chloro-3-nitrobenzene (3-CNB) is an aromatic halo-amine compound used as chemical intermediate for the production of several fine chemicals like pharmaceuticals, dyes, agricultural chemicals, etc. The stable isotope ratio analysis has drawn attention in numerous fields such as agricultural, food authenticity, biochemistry, etc. The objective of the current research was to investigate the impact of the biofield energy treatment on the isotopic abundance ratios of PM+1/PM, PM+2/PM and PM+3/PM in 3-CNB using gas chromatography - mass spectrometry (GC-MS). The sample, 3-CNB was divided into two parts - one part was denoted as control and another part was referred as biofield energy treated sample that was treated with biofield energy (The Trivedi Effect®). T1, T2, T3, and T4 were represented to different time interval analysis of the biofield treated 3-CNB. The GC-MS spectra of the both control and biofield treated 3-CNB indicated the presence of molecular ion peak [M+] at m/z 157 (calculated 156.99 for C6H4ClNO2) along with same pattern of fragmentation. The relative intensities of the parent molecule and other fragmented ions of the biofield treated 3-CNB were improved as compared to the control 3-CNB. The percentage change of the isotopic abundance ratio of PM+1/PM was significantly increased in the biofield treated 3-CNB at T1, T2 and T3 by 11.62, 18.50, and 29.82%, respectively with respect to the control 3-CNB. Accordingly, the isotopic abundance ratio of PM+2/PM in the biofield treated 3-CNB at T2 and T3 was significantly improved by 15.22 and 35.09%, respectively as compared to the control sample. The isotopic abundance ratios of PM+1/PM and PM+2/PM in the biofield treated 3-CNB at T1 and T4 were changed as compared to the control sample. The percentage change of the isotopic abundance ratio of PM+3/PM was enhanced in the biofield treated 3-CNB at T1, T2, T3, and T4 by 4.67, 18.69, 31.31 and 6.08%, respectively as compared to the control 3-CNB. The isotopic abundance ratios of PM+1/PM, PM+2/PM and PM+3/PM in the biofield treated 3-CNB changed with the time. So, the biofield energy treated 3-CNB might exhibit the altered isotope effects such as altered physicochemical and thermal properties, binding energy, and the rate of the chemical reaction as compared to the control sample. The biofield energy treated 3-CNB might assist in designing for the synthesis of pharmaceuticals, agricultural chemicals, dyes, corrosion inhibitors and other several useful industrial chemicals.

Abstract:
The aim of the study was to evaluate the effect of the The Trivedi Effect®- Consciousness Energy Healing Treatment based new proprietary herbomineral formulation and cell medium (DMEM) on various skin health parameters using HFF-1, HaCaT, and B16-F10 cell lines. It contained minerals (zinc chloride, sodium selenate, and sodium molybdate), L-ascorbic acid, along with the mixture of Centella asiatica extract and tetrahydrocurcumin (THC). The test formulation and DMEM were divided into two parts each, one part of each was coded as untreated (UT), while the second part of each was treated with the Biofield Treatment by Johanne Dodon and denoted as the Biofield Energy Treated (BT) test items. MTT assay result showed that the test formulation was safe and nontoxic up to 80 µg/mL concentration. The fibroblast cell proliferation assay using BrdU method showed a significant increased cell proliferation at 2.13, 8.75, and 17.53 µg/mL by 3.90%, 14.68% and 29.54%, respectively in the BT-DMEM + BT-Test formulation group compared to the untreated group. The collagen data showed an increased synthesis by 7.42% and 3.84% in the UT-DMEM + BT-Test formulation and BT-DMEM + BT-Test formulation groups, respectively at 0.625 µg/mL with respect to the untreated group. Similarly, the elastin synthesis was increased by 19.8% and 25.8% in the UT-DMEM + BT-Test formulation and BT-DMEM + BT-Test formulation groups, respectively at 5 µg/mL with respect to the untreated group. However, the Biofield Energy Treated test formulation showed an increased level of hyaluronic acid by 1.7% in UT-DMEM + BT-Test formulation group compared to the untreated group. Melanin synthesis inhibition was observed by 15.21% and 11.43% in UT-DMEM + BT-Test Formulation and BT-DMEM + BT-Test Formulation groups, respectively at 0.125 µg/mL compared with the untreated group in B16-F10 melanoma cell line. Anti-wrinkling effects showed an improved cell viability by 7.65% at 1.25 µg/mL in the BT-DMEM + BT-Test formulation experimental group compared with the untreated test group. In addition, the Biofield Energy Treated Test formulation/DMEM showed a significant wound healing activity and high cellular migration of fibroblast and keratinocytes in HFF-1 and HaCaT cells, respectively. Overall, the data suggested that Biofield Treated formulation/DMEM could be helpful for skin healing, improvement the skin health, elasticity, and tightness, as well as, improving skin health issues such as wrinkling, pigmentation disorders, redness, swelling, skin cancer, aging, rashes, and skin sagging.
