TL;DR: Six green leafy vegetables and herbs – spinach, amaranth, bengal gram, cauliflower, mint, coriander and carrots – were analyzed for moisture, protein,ascorbic acid, β-carotene, total iron, ionizable iron, in vitro iron, copper, manganese and zinc.
Abstract: Six green leafy vegetables and herbs – spinach, amaranth, bengal gram, cauliflower, mint, coriander and carrots – were analyzed for moisture, protein,ascorbic acid, β-carotene, total iron, ionizable iron (as % of total iron) in vitro iron (% of total iron), copper, manganese and zinc. Moisture content of the leaves and carrots varied from 75.1 percent (bengal gram) to 95.4 percent (carrot) and protein from 9.83 percent (carrots) to 30.9 (mint) percent. Ascorbic acid, β-carotene, total iron and ionizable iron contents were at a maximum in case of bengal gram leaves whereas level of ionizable iron and in vitro iron as a percent of total iron was highest in carrots. Copper, manganese and zinc contents were maximum in spinach.

TL;DR: In this paper, the calcium enriched mango yogurt was prepared after fortification of pasteurized yogurt mix with 50mg Ca/100ml of calcium lactate, this level selected from a preliminary study of sensory evaluation, and a significant difference was observed in tan δ values of control and calcium fortified fruit yogurt indicating similar nature of bonds involved in the gel structure formation of both the yogurt samples.
Abstract: There has been great demand of calcium fortified dairy products as they can serve as an ideal vehicle for carrying extra calcium to fulfill the nutritional needs but there is need to generate information on the effect of fortification of calcium on the physical properties of these products. In the present study, the calcium enriched mango yogurt was prepared after fortification of pasteurized yogurt mix with 50 mg Ca/100 ml of calcium lactate, this level selected from a preliminary study of sensory evaluation. Fortification of yogurt with calcium lactate at this level significantly (P 0.05) difference was observed in tan δ values of control and calcium fortified fruit yogurt indicating similar nature of bonds involved in the gel structure formation of both the yogurt samples. The more firm structure of the calcium fortified fruit yogurt is thus attributed to the higher extent of colloidal calcium phosphate cross-linking between casein micelles due to increased calcium content by fortification. Also flavor, color, and body and texture scores of control and calcium fortified fruit yogurt did not show any significant difference (P>0.05).

TL;DR: In this article, the authors performed searches for resonant and nonresonant pair-produced Higgs bosons (HH) decaying respectively into l nu l nu, through either W or Z bosons, and b (b) over bar.
Abstract: Searches for resonant and nonresonant pair-produced Higgs bosons (HH) decaying respectively into l nu l nu, through either W or Z bosons, and b (b) over bar are presented The analyses are based on a sample of proton-proton collisions at root s = 13 TeV, collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 359 fb(-1) Data and predictions from the standard model are in agreement within uncertainties For the standard model HH hypothesis, the data exclude at 95% confidence level a product of the production cross section and branching fraction larger than 72 fb, corresponding to 79 times the standard model prediction Constraints are placed on different scenarios considering anomalous couplings, which could affect the rate and kinematics of HH production Upper limits at 95% confidence level are set on the production cross section of narrow-width spin-0 and spin-2 particles decaying to Higgs boson pairs, the latter produced with minimal gravity-like coupling

TL;DR: In this paper, a review of self-healing composites is presented, including carbon fiber laminates, microcapsules containing rejuvenator along with graphene/hexamethoxymethylmelamine (HMMM) hybrid shells and supramolecular elastomer.
Abstract: Failure happens in composites after prolonged degradation process due to micro cracks. Thereafter repairing is not possible at remote locations in the way to enhance reliability and endurance of composites. Self-healing composites are fabricated to heal cracks and damages if there will be any to restrict failure and enhance the longevity of structures. Therefore, maintenance task is quite simplified. This review aims to provide summarized information on the recent developments in the field of self-healing composites. Initially, fabrication and characterization techniques have been reviewed as much as possible for self-healing carbon fiber laminates, microcapsules containing rejuvenator along with graphene/hexamethoxymethylmelamine (HMMM) hybrid shells and supramolecular elastomer. This paper also outlines numerical methods in its middle section to explore functionality recoveries in self-healing composites and to study improvement in mechanical properties of these smart composites. Thereafter, applications of shape memory alloy and shape memory polymer in advanced CNTs reinforced self-healing composites are also discussed. Composite material with carbon nanotube sheets (CNS) is discussed as sustainable self-healing material as it can maintain its temperature-similar to living species. Future application will be based on these smart self-healing composites and thus it becomes important to us to compile this review article.

TL;DR: In this paper, a theory of the spontaneous formation of nanoscale porous structures in aluminum oxide films growing during aluminum anodization is presented, based on the Butler-Volmer relation describing the exponential dependence of the current on the overpotential and the dependence of activation energies of the oxide-electrolyte interfacial reactions on the Laplace pressure and the elastic stress in the oxide layer.
Abstract: A theory of the spontaneous formation of nanoscale porous structures in aluminum oxide films growing during aluminum anodization is presented. The main elements of this theory are the Butler-Volmer relation describing the exponential dependence of the current on the overpotential and the dependence of the activation energies of the oxide-electrolyte interfacial reactions on the Laplace pressure and the elastic stress in the oxide layer. Two cases are considered, distinguished by whether the elastic stress dependence is significant or not. In the case when the effect of elastic stress is negligible, a linear stability analysis predicts a long-wave instability resulting from the field-assisted dissolution reaction; its competition with the stabilizing effect of the Laplace pressure due to the surface energy provides the wavelength selection mechanism. A weakly nonlinear analysis near the instability threshold reveals that the nonlinear dynamics of the interface perturbations is governed by the Kuramoto-Sivashinsky equation. The spatiotemporally chaotic solutions of this equation can explain the formation of spatially irregular pore arrays that are observed in experiments. In the case when the effect of elastic stress in the oxide layer is significant we show that the instability can transform from the long-wave type to the short-wave type. A weakly nonlinear analysis of the short-wave instability shows that it leads to the growth of spatially regular, hexagonally ordered pore arrays, as observed experimentally.

TL;DR: This book by a teacher of statistics (as well as a consultant for "experimenters") is a comprehensive study of the philosophical background for the statistical design of experiment.
Abstract: THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

TL;DR: In this article, a fast Fourier transform method of topography and interferometry is proposed to discriminate between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour generation techniques.
Abstract: A fast-Fourier-transform method of topography and interferometry is proposed. By computer processing of a noncontour type of fringe pattern, automatic discrimination is achieved between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour-generation techniques. The method has advantages over moire topography and conventional fringe-contour interferometry in both accuracy and sensitivity. Unlike fringe-scanning techniques, the method is easy to apply because it uses no moving components.

TL;DR: This review attempts to cover all aspects, including underlying principles and key functional features of TiO(2), in a comprehensive way and also indicates potential future directions of the field.
Abstract: TiO(2) is one of the most studied compounds in materials science. Owing to some outstanding properties it is used for instance in photocatalysis, dye-sensitized solar cells, and biomedical devices. In 1999, first reports showed the feasibility to grow highly ordered arrays of TiO(2) nanotubes by a simple but optimized electrochemical anodization of a titanium metal sheet. This finding stimulated intense research activities that focused on growth, modification, properties, and applications of these one-dimensional nanostructures. This review attempts to cover all these aspects, including underlying principles and key functional features of TiO(2), in a comprehensive way and also indicates potential future directions of the field.
