Medical aesthetics – Current trends and a review of its applications
No full textMedical aesthetics is the use of a procedure or product for a therapeutic indication which is conventionally used for aesthetics. Several medical conditions are now being treated with products, procedures or equipment that are conventionally used for aesthetic indications. This has widened the scope of treatment modalities available for dermatologists to treat various indications that fall outside the purview of aesthetic dermatology. The authors present aesthetic treatment modalities and procedures which can be used for medical aesthetics, their present-day status and usefulness in field of therapeutics with a review of published literature from “Medline” (via “PubMed”), “Cochrane,” the Virtual Health Library, and Google Scholar
Ideas for rent: an overview of markets for technology
No full textThis article surveys some of the recent literature on technology markets, and summarizes its main issues and insights. We structure our analysis in three parts: the supply and demand of technology; the factors that condition the formation and growth of technology markets; industry structure and dynamic issues. In addition, we summarize some of the studies that have tried to document the size and growth of these markets. We find that the literature has focused mainly on the supply of technology, but several other aspects of these markets remain under-studied, including the demand for external technology, the role of uncertainty in technology markets, and the dynamic interaction between industry structure and the market for technology. Understanding these will illuminate whether markets for technology will continue to grow or remained confined to pockets of the economy. Copyright 2010 The Author 2010.

Metrics for analytics and visualization of big data with applications to activity recognition
No full textActivity recognition systems detect the hidden actions of an agent from sensor measurements made on the agents' actions and the environmental conditions. For such systems, metrics are important for both performance evaluation and visualization purposes. In this thesis, such metrics are developed and illustrated. For human activity recognition datasets, a reporting structure is described to visualize the metrics in a systematic manner. The other contribution of this thesis is to describe a visualization tool for estimating the orientation (attitude) of a rigid body from streaming motion sensor (accelerometer and gyroscope) data. A feedback particle filter (FPF) is implemented algorithmically to solve the estimation problem.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-05-01The student, Rohan Arora, accepted the attached license on 2016-04-25 at 10:47.The student, Rohan Arora, submitted this Thesis for approval on 2016-04-25 at 10:48.This Thesis was approved for publication on 2016-04-27 at 15:05.DSpace SAF Submission Ingestion Package generated from Vireo submission #9459 on 2016-07-07 at 14:17:57Made available in DSpace on 2016-07-07T21:18:02Z (GMT).

Aerospace dermatology
No full textEvolutionarily, man is a terrestrial mammal, adapted to land. Aviation and now space/microgravity environment, hence, pose new challenges to our physiology. Exposure to these changes affects the human body in acute and chronic settings. Since skin reflects our mental and physical well-being, any change/side effects of this environment shall be detected on the skin. Aerospace industry offers a unique environment with a blend of all possible occupational disorders, encompassing all systems of the body, particularly the skin. Aerospace dermatologists in the near future shall be called upon for their expertise as we continue to push human physiological boundaries with faster and more powerful military aircraft and look to colonize space stations and other planets. Microgravity living shall push dermatology into its next big leap-space, the final frontier. This article discusses the physiological effects of this environment on skin, effect of common dermatoses in aerospace environment, effect of microgravity on skin, and occupational hazards of this industry
Three Dimensional High Contrast Gratings based Hollow Core Waveguide for Chip Scale Integrated Optical Interconnects
No full textME, ECEDThree dimensional high contrast gratings based hollow core waveguide is a potential
candidate for telecommunication systems which provides a promising platform to realize
integrated optical interconnects. These have been comprehensively studied over the years
due to its diverse applications in the communication systems. With advancement of
technologythese days as we are doing scaling the size of devices and distance between the
devices is reducing which makes interconnects more important in communication system. To
maintain such high speed and small size optical interconnects are required which can play
crucial role to achieve today’s high speed large bandwidth requirementsThe high reflectivity,
high speed and high bandwidth of HCGs based Hollow waveguide is one of the key
component for integrated chip scale optical interconnects.This can be used to guide light and
transmit Tb/s data over the communication link and attracted a lot of attention for next
generation communication network as well as high performance computing applications.SOI
is an ideal platform for the development of passive optical interconnects like Hollow
waveguide. Several key challenges exist in developing the waveguide, including fabrication
difficulties, dispersion and non linearity. Usinghigh contrast gratings, the fabrication
difficulties can be minimized. Dispersion remains to be the most dominant source in the
system of data loss. From the aspects of reflectivity, bandwidth, dispersion and non linearity,
using high contrast gratings in waveguide approach is widely popular. Modified approach
involves the high contrast gratings with high index material surrounded by a low-index
material. The refractive index difference is maintained high that is greater than 2.4 which
provides high reflectivity. Parameters on which reflectivity of waveguide mainly depends are
grating thickness (tg), grating period (Λ), and duty cycle (η). Important design attribute is the
sub wavelength size of gratings
No pain, no gain: an examination of the effects of self-threat on creativity
No full textThis paper investigates how different forms of self-threat influences different types of creativity. It examines which forms of self-threat hinder or boost creative capacity. The author illustrates the proposition that the threat from fixed self-domain enhances convergent creativity and that threats from dynamic self-domain enhance divergent creativity. This research adds to current knowledge of creativity literature by highlighting self-threats and it differentiates effects on both divergent creativity and convergent creativity.February 201
Formulation and evaluation of controlled release matrix mucoadhesive tablets of domperidone using Salvia plebeian gum
No full textThe aim of study was to prepare controlled release matrix mucoadhesive tablets of domperidone using Salvia plebeian gum as natural polymer. Tablets were formulated by direct compression technology employing the natural polymer in different concentrations (5, 10, 15 and 20% w/w). The prepared batches were evaluated for drug assay, diameter, thickness, hardness and tensile strength, swelling index, mucoadhesive strength (using texture analyzer) and subjected to in vitro drug release studies. Real-time stability studies were also conducted on prepared batches. In vitro drug release data were fitted in various release kinetic models for studying the mechanism of drug release. Tensile strength was found to increase from 0.808 ± 0.098 to 1.527 ± 0.10 mN/cm 2 and mucoadhesive strength increased from 13.673 ± 1.542 to 40.378 ± 2.345 N, with an increase in the polymer concentration from 5 to 20% (A1 to A4). Swelling index was reported to increase with both increase in the concentration of gum and the time duration. The in vitro drug release decreased from 97.76 to 83.4% (A1 to A4) with the increase in polymer concentration. The drug release from the matrix tablets was found to follow zero-order and Higuchi models, indicating the matrix-forming potential of natural polymer. The value of n was found to be between 0.5221 and 0.8992, indicating the involvement of more than one drug release mechanism from the formulation and possibly the combination of both diffusion and erosion. These research findings clearly indicate the potential of S. plebeian gum to be used as binder, release retardant and mucoadhesive natural material in tablet formulations
