PHARMACOLOGICAL & PHYTOCHEMICAL EVALUATION OF YOGRAJ CHURNA: AN COMPOUND AYURVEDIC FORMULATION
No full textYograj churna is an important Ayurvedic formulation containing Triphala (Amlakhi – Embelica officinalis, Bibhitaki – Terminalia bellerica, Haritaki – Terminalia chebula), Triakatu (Sunthi-Zingiber officinele, Maricha- Piper nigrum, Pippali – Piper longum), Vidanga (Embelia ribes Burm. f), Chitrakmula (Plumbago zeylanica Linn), Suddhashilajit (Asphaltum punjabianum), Swarnamakshika (Copper pyrite (CuFeS2), Raupyamakshika (Iron pyrite (Fe2S3), Lohabhasma (Iron Powder) and Mirsi (sugar) as main ingredient. of all the constituent were available and prepared accordingly as mentioned in Charak samhita, Chitsasthana, Panduroga adhyaya in Ayurvedic pharmacy, BHU. Though Yograj churna is very effective in anemia, it is useful in different disorder and as an excellent rejuvenator. But till date no work has been carried out to standardize the formulation. Hence the present study was undertaken to standardize the compound Ayurvedic formulation through Pharmacognostical and pharmaceutical evaluation. The sample was subjected for various Phytochemical parameters like water soluble extractive (11.39%w/w), alcohol soluble extractive (23.63% w/w), ash value (39.19% w/w), acid insoluble ash (36.38% w/w), loss on drying (8.86% w/w), the pH (5.03), TLC. The TLC, solvent system was methanol:ethyl acetate (by trial and error method), showed the presence of 4 spots Rf (0.1, 0.46. 0.76, 0.9). The phytochemical analysis showed the presence of Alkaloids, Glycosides, Saponins and Tanins. Thus the physiochemical and microscopic characters achieved may provide guidelines for standardization of formulation, Yograj churna
Determination of microbial load, total Phenolic and flavonoids contents in polyherbal formulation “yograj guggulu vati”
No full textYograj guggulu vati (YGV), a polyherbal formulation is recommended for the management of diseases like arthritic, anodyne or analgesic, spasm, muscle relaxant, flatulence, digestive problem, cough, hyperglycaemia, fat burner and obesity. Though Yograj guggulu vati is widely used for the treatment of diseases in Ayurvedic System of Indian Medicine, but till date, it’s Phenolic and flavonoids contents and contamination studies have not been carried. In the present article, we evaluated the total phenolic and flavonoids contents and contamination of YGV. Total phenolic contents were evaluated by Folin Ciocalteu reagent. Aluminum chloride colorimetric method was used for the determination of total flavonoid contents. Contamination study such as microbial load was also performed. Microbial load study revealed that total bacterial counts and total fungal counts were under limits. The total phenolic content and total flavonoid content were 190.16 mg/g and 20.87 mg/ g dry extract respectively. Microbial load studies showed that the formulation has a good quality and purity. Presence of abundance phenolic and flavonoids compound indicated that YGV can be used for different biological activities.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Arrhythmia Management: Control of Alternans & VIEgram for analysis and visualization of electrograms to aid Atrial Fibrillation Treatment
No full textUniversity of Minnesota M.S. thesis.July 2020. Major: Biomedical Engineering. Advisor: Alena Talkachova. 1 computer file (PDF); vi, 59 pages.Arrhythmia management - prediction, prevention and control of arrhythmias, is difficult mainly due to its spatiotemporal complexity and the poor understanding of mechanisms causing them. Therapies for managing arrhythmias can be focused at two macroscopic levels, namely cellular level and tissue/organ level. At cellular level, arrhythmias can be prevented by reviving the abnormal electrophysiological function of myocytes and thus preventing it from getting evolved into dangerous reentrant arrhythmias at the tissue level. For example, ventricular arrhythmias can be prevented by employing a pacing protocol to control cardiac alternans at cellular level. Whereas at tissue/organ level, the arrhythmia which is already present can be controlled. For example, the catheter ablation procedure, a procedure where tissue causing abnormal electrical activity is ablated, is used to treat AF on an organ level to return the heart back to its normal sinus rhythm. Also, at an organ level we can deal with the pre-existing factors contributing to arrhythmogenesis. Furthermore, a visualization of all the manifestations of arrhythmias on an organ level (3D models of a patient's heart) will not only help in understanding the complex spatiotemporal mechanisms behind them but will also facilitate the development of new techniques to treat them.Thakare, Sanket Yograj.

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
