    Surface Tensiometry Approach to Characterize Cosmetic Products in the Beauty Sector

    No full text
    The term “surface” of a material indicates the interface between a solid or liquid and the air and the term “tensiometry” represent an analytical technique capable to characterize the surface free energy of a solid and the surface tension of a liquid. The new term “surface tensiometry” indicates the analytical technique capable to characterize surface free energy and surface tension using the contact angle method. The main treatments for face skin are mascara, eye contour cream, serum, chemical peel, facial mask, eye shadow, lipstick, foundation, night/day cream. The integrated analytical approach (IAA) for these kinds of cosmetics is still not widely applied because the surface tensiometry is not often used in the beauty farm. The IAA represents an integrated approach to study the bulk chemical composition (e.g., by spectroscopic methods) bulk structure (e.g. by rheological measurements) and surface characteristics (e.g. by surface tensiometry) on the same material sample and at the same time. A deeper investigation on the surface free energy of formulations for face skin treatments could give information on their bioadhesivity with the skin. The surface tensiometry can improve the quality of these cosmetics by a non-invasive and fast way optimizing their industrial production

    Chess Is Hard Even for a Single Player

    We introduce a generalization of "Solo Chess", a single-player variant of the game that can be played on chess.com. The standard version of the game is played on a regular 8 × 8 chessboard by a single player, with only white pieces, using the following rules: every move must capture a piece, no piece may capture more than 2 times, and if there is a King on the board, it must be the final piece. The goal is to clear the board, i.e, make a sequence of captures after which only one piece is left. We generalize this game to unbounded boards with n pieces, each of which have a given number of captures that they are permitted to make. We show that Generalized Solo Chess is NP-complete, even when it is played by only rooks that have at most two captures remaining. It also turns out to be NP-complete even when every piece is a queen with exactly two captures remaining in the initial configuration. In contrast, we show that solvable instances of Generalized Solo Chess can be completely characterized when the game is: a) played by rooks on a one-dimensional board, and b) played by pawns with two captures left on a 2D board. Inspired by Generalized Solo Chess, we also introduce the Graph Capture Game, which involves clearing a graph of tokens via captures along edges. This game subsumes Generalized Solo Chess played by knights. We show that the Graph Capture Game is NP-complete for undirected graphs and DAGs. © N.R. Aravind, Neeldhara Misra, and Harshil Mittal

    Electronic absorption spectrum and decay kinetics of the benzyl radical in solution

    During studies of the transient optical spectra of the intermediates produced in the flash photolysis of various substituted aromatic compounds in aqueous solution (L. J. Mittal, J. P. M., and E. H., unpublished work), in addition to the characteristic spectrum of the benzyl radical with λmax at 318 nm and at â^¼307 nm we observed a strong absorption at wavelengths below 290 nm

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The 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

    Healing Effect of Botox in Dental Office

    No full text
    ABSTRACT In this era of passion to look beautiful, various new technologies are emerging to enhance and improve the physical appearance of people. Botox is emerging as one such popular treatment to improve various facial anomalies. Minimally invasive treatment can be done by botox, which can expand our therapeutic options for the benefit of our patients. The aim of this article is to elaborate the healing aspect of this toxin, i.e., botox. How to cite this article Mittal R, Singla M, Aggarwal H. Healing Effect of Botox in Dental Office.

    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    We 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

    Sharma&ndash;Taneja&ndash;Mittal Entropy and Its Application of Obesity in Saudi Arabia

    No full text
    This paper presents several nonparametric estimators for the Sharma&ndash;Taneja&ndash;Mittal entropy measure of a continuous random variable with known support, utilizing spacing, a local linear model, and a kernel function. The properties of these estimators are discussed. Their performance was also examined through real data analysis and Monte Carlo simulations. In the Monte Carlo experiments, the proposed Sharma&ndash;Taneja&ndash;Mittal entropy estimators were employed to create a test of goodness-of-fit under the standard uniform distribution. The suggested test statistics demonstrate strong performance, as evidenced by a comparison of their power with that of other tests for uniformity. Finally, we examine a classification issue in the recognition of patterns to underscore the significance of these measures

    Agricultural Productivity Trends in India: Sustainability Issues

    No full text
    The sustainability issue of the crop productivity is fast emerging. The post-Green Revolution phase is characterized by high input-use and decelerating total factor productivity growth (TFPG). The agricultural productivity attained during the 1980s has not been sustained during the 1990s and has posed a challenge for the researchers to shift the production function upward by improving the technology index. It calls for an examination of issues related to the trends in the agricultural productivity, particularly with reference to individual crops grown in the major states of India. Temporal and spatial variations of TFPG for major crops of India have also been examined.Agricultural and Food Policy,

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We 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
