Physics , 2010,
Abstract: On January 17, 2005 a complex radio event associated with an X3.8 SXR flare and two fast Halo CMEs (CME1 & CME2 henceforward) in close succession was observed. We present combined ARTEMIS-IV & WIND WAVES dynamic spectra which provide a complete view of the radio emission induced by shock waves and electron beams from the low corona to about 1 A.U. These are supplemented with data, from the Nan\c{c}ay Radioheliograph (NRH), GOES, EIT and LASCO for the study of the associated flare and CME activity.
Interplanetary Consequences of a Large CME  [PDF]
M. Lahkar,P. K. Manoharan,K. Mahalakshmi,K. Prabhu,G. Agalya,S. Shaheda Begum,P. Revathi
Physics , 2009, DOI: 10.1007/978-3-642-02859-5_64
Abstract: We analyze a coronal mass ejection (CME) which resulted from an intense flare in active region AR486 on November 4, 2003. The CME propagation and speed are studied with interplanetary scintillation images, near-Earth space mission data, and Ulysses measurements. Together, these diverse diagnostics suggest that the internal magnetic energy of the CME determines its interplanetary consequences.

Radial Flow Pattern of a Slow CME  [PDF]
Li Feng,Bernd Inhester,Weiqun Gan
Physics , 2015,
Abstract: Height-time plots of the leading edge of coronal mass ejections (CME) have often been used to study CME kinematics. We propose a new method to analyze the CME kinematics in more detail by determining the radial mass transport process throughout the entire CME. Thus our method is able to estimate not only the speed of the CME front but also the radial flow speed inside the CME. We have applied the method to a slow CME with an average leading edge speed about 480 km s$^{-1}$. In the Lagrangian frame, the speed of the individual CME mass elements stay almost constant within 2 and 15 R$_S$, the range over which we analyzed the CME. Hence we have no evidence of net radial forces acting on parts of the CME in this range nor of a pile-up of mass ahead of the CME. We find evidence that the leading edge trajectory obtained by tie-pointing may gradually lag behind the Lagrangian front-side trajectories derived from our analysis. Our results also allow a much more precise estimate of the CME energy. Compared with conventional estimates using the CME total mass and leading-edge motion, we find that the latter may overestimate the kinetic energy and the gravitational potential energy.
CME observations from STEREO  [PDF]

Physics , 2009, DOI: 10.1007/978-3-642-02859-5_25
Abstract: Coronal mass ejections (CMEs) are spectacular ejections of material from the Sun as seen in the coronal field of view. Regular observations are possible with both ground-based and space-based coronagraphs. I present our current understanding of CMEs based on multi-wavelength observations from groundbased instruments as well as from space missions such as SoHO. Based on the continuous and multi-wavelength observations of CMEs from SoHO over a period of more than a solar cycle, the physical properties of CMEs are described. Recent observations of CMEs with the SECCHI coronagraphs, namely COR1 and COR2 aboard the twin STEREO spacecrafts A and B are also presented. STEREO surpasses previous missions by providing a 3-D view of CME structure from two vantage points. Applications of STEREO observations to 3-D reconstructions of the leading edge of CMEs are described.
Global Trends of CME Deflections Based on CME and Solar Parameters  [PDF]

Physics , 2014, DOI: 10.1088/0004-637X/805/2/168
Abstract: Accurate space weather forecasting requires knowledge of the trajectory of coronal mass ejections (CMEs), including any deflections close to the Sun or through interplanetary space. Kay et al. 2013 introduced ForeCAT, a model of CME deflection resulting from the background solar magnetic field. For a magnetic field solution corresponding to Carrington Rotation (CR) 2029 (declining phase, April-May 2005), the majority of the CMEs deflected to the Heliospheric Current Sheet (HCS), the minimum in magnetic pressure on global scales. Most of the deflection occurred below 4 Rs. Here we extend ForeCAT to include a three dimensional description of the deflecting CME. We attempt to answer the following questions: a) Do all CMEs deflect to the magnetic minimum? and b) Does most deflection occur within the first few solar radii (~4 Rs)? Results for solar minimum and declining phase CMEs show that not every CME deflects to the magnetic minimum and that the deflection is typically determined below 2 Rs. Slow, wide, low mass CMEs in declining phase solar backgrounds with strong magnetic field and magnetic gradients exhibit the largest deflections. Local gradients related to active regions tend to cause the largest deviations from the deflection predicted by global magnetic gradients, but variations can also be seen for CMEs in the quiet sun regions of the declining phase CR. We show the torques due to differential forces along the CME can cause rotation about the CME's toroidal axis.
CME ON CLINICAL RESEARCH  [PDF]
Suneel. I. Majagi,S. S. Torgal,S. V. Hiremath
International Journal of Research in Ayurveda and Pharmacy , 2012,
Abstract: Safety and efficacy are the two major concerns for any drug therapy. Globally clinical research plays an inevitable role in bringing a new molecule into the market after its synthesis by the pharmaceutical industries. Availability of large patient population, highly educated and skilled manpower, wide spectrum of diseases and favorable economic environment imply India’s potential as a global hub for clinical research. Pharmaceutical companies and Clinical Research Organization (CRO)s will require many trained personnel to carry out the clinical research. Keeping in mind these facts a CME with the theme of “Clinical research” had been jointly organized by the Dept of pharmacology, K.L.E University’s J.N.M.C, Belgaum and Indian Pharmacological Society (I.P.S), Belgaum branch on 20th February 2010. In the first scientific session, Dr.P.A.Patil (JNMC) spoke on “Preclinical studies”. In vitro and in vivo experiments of various doses of ‘study drug’ can obtain preliminary efficacy, toxicity and pharmacokinetic information suggesting the scientific merit for further development as an investigational new drug (IND). Local or systemic toxicity studies can be conducted (ex: urine analysis, blood biochemical assay, gross and microscopic pathology etc). Dr. B.J. Mahendra Kumar (KLE University’s College of pharmacy) talked on “Role of Drug Controller General of India (DCGI) in Clinical Trials”. He explained about Drug and cosmetic acts/rules, requirements/guidelines for permission to import and/or to manufacture new drugs or to undertake clinical trials i.e. Schedule Y and its appendices. Dr.N.M.Patil (JNMC) elaborated about “Ethical issues in clinical trials”. Ethics is required to: avoid exploitation of the subjects (maintain safety and wellbeing), protect vulnerable groups, children, disabled, elderly etc. Independent Ethics Committees (IEC) and Institutional Review Boards (IRB) are concerned with medical ethics. IECs review, regulate, monitor and supervise the clinical trials or the research projects. Ethical decision is taken without coercion, influence, inducement and intimidation. Dr.S.S.Torgal (JNMC) spoke on “Introduction to clinical trials”. A systematic study of a new drug in human subjects to generate data for discovering and/or verifying the clinical, pharmacological (pharmacodynamic / pharmacokinetic) and/or adverse effects with the objective of determining safety and/or efficacy of the new drug is known as clinical trial (Phase I, II, III and IV). There are many types of trials viz., Prevention trials, Screening trials, Diagnostic trials, Treatment tri
