      • Self-rated ability to follow instructions for four mental states described in yoga texts

        Raghavendra Bhat Ramachandra,Shirley Telles,Nagendra Rama Rao Hongasandra 셀메드 세포교정의약학회 2012 TANG Vol.2 No.3

        There were no studies available measuring the ability to follow instructions for meditation. Hence, the present study was planned to assess the ability to follow instructions for the four mental states viz., cancalata (random thinking), ekagrata (non-meditative concentration), dharana (focused meditation) and dhyana (defocused meditation or effortless meditation) described in yoga texts. Sixty male volunteers with ages ranging from 18 to 31 years (group mean age ± S.D., 22.78 ± 2.73) participated in the study. They were assessed using a visual analog scale immediately after each of the four states on four different days. The results showed that following dharana, scores on the visual analog scale were significantly lower compared to those related to cancalata, ekagrata and dhyana. Hence, dharana is the most difficult of the four states.

        Geochemistry of Neoproterozoic limestones of the Shahabad Formation, Bhima Basin, Karnataka, southern India

        Ramasamy Nagarajan,Jayagopal Madhavaraju,John S. Armstrong-Altrin,Raghavendra Nagendra 한국지질과학협의회 2011 Geosciences Journal Vol.15 No.1

        Major, trace and rare earth element (REE) geochemistry of carbonate rocks of the Neoproterozoic Shahabad Formation, southern India were studied in order to investigate the depositional environment and source for the REEs. The PAAS (Post Archaean Australian Shale) normalized REE + Y pattern of Shahabad limestones have consistent seawater-like pattern i.e., i) LREE depletion (average (Nd/Yb)_(SN) = 0.64 ± 0.08), ii) negative Ce anomaly, iii) positive Gd anomaly (average Gd_(SN)/Gd^* = 1.05 ± 0.16), iv) superchondritic Y/Ho ratio (average Y/Ho = 38.13 ± 21.35). The depletion of LREE and enrichment of HREE are clearly indicated by the (La/Yb)_(SN), (Dy/Yb)_(SN) and (Nd/Yb)_(SN) ratios, which suggest the retention of seawater characteristics in these limestones. The negative Ce anomaly reflects the incorporation of REE directly from seawater or from the pore water under oxic condition, and also reveals the mixing of two-component systems with terrigenous clay (detrital) in the marine sediments. The terrigenous input in these limestones is confirmed by positive correlation of REE with Al_2O_3, negative correlation of REE with CaO and differences in Y/Ho ratios. V, Cr, and Sc, are positively correlated with Ti, and strong positive correlation of REE with Fe_2O_3, Ni, Cr, Sc, and Y also indicate the presence of terrigenous materials in the Shahabad limestones.
