Introduction
No full textOver the last 15–20 years there has been a lot of buzz surrounding the word “nanotechnology” [1, 2, 3, 4, 5, 6, 7]. A lot is being printed in the press and being aired in the media regarding how this new technology is changing the world around us with myriad applications. It is already touching the everyday lives of people in various avatars such as nanoparticles containing sunscreen lotions, dirt-resistant glass/paint with nanocoatings, the lab on a chip (also known as the micro testing and analyzing system; µ-TAS in short), and the various nanocomposite materials. This chapter looks to introduce the readers to what nanotechnology is about
Factors associated with minimum dietary diversity failure among Indian children
No full textAbstract Recognising the importance of infant and young child feeding practices during the first 2 years of life, the World Health Organization's Global Nutrition Monitoring Framework developed a minimum dietary diversity (MDD) indicator for feeding children aged 6–23 months. MDD is defined as the consumption of food items from five or more groups out of a total of eight food groups. Food intake from less than five food groups is considered minimum dietary diversity failure (MDDF). Using the nationally representative National Family Health Survey (NFHS) dataset, the present study assessed the trend in MDDF between 2005–6 and 2015–16 and the factors associated with MDDF among children aged 6–23 months during 2015–16. The NFHS conducted in 2005–6 and 2015–16 covered a sample of 14 419 and 74 078 children aged 6–23 months, respectively. Overall, the MDDF reduced from 87⋅4 % (95 % confidence interval (95 % CI) 86⋅8 %, 87⋅9 %) in 2005–6 to 80⋅6 % (95 % CI 80⋅1 %, 81⋅0 %) in 2015–16. Multivariable logistic regression analysis revealed that increased child's age, second and third birth order children, higher maternal age and education, mass media exposure of mothers and more than four antenatal care visits had a negative association with the MDDF. Children living in rural areas and residing in high-focus states of India were observed with higher odds of experiencing MDDF. Exposure to community healthcare services was negatively associated with MDDF, and anaemic children were more likely to have MDDF. Socioeconomic status of mothers and children and encouragement of maternal and child healthcare use could be helpful in devising context-specific intervention to mitigate MDDF
Investigating the effect of machining parameters on EDMed components a RSM approach / Manoj Kumar Pradhan and Chandan Kumar Biswas
No full textThe effects of the machining parameters in electrical-discharge machining on the machining characteristics of AISI D2 steel workpiece has been investigated in this research. The response functions considered are Material Removal Rate (MRR) and surface roughness (Ra), while machining variables are pulse current, pulse on time, pause time and gap voltage. A Response surface methodology was used to reduce the total number of experiments. Empirical models correlating process variables and their interactions with the said response functions have been established. The
significant parameters that critically influenced the machining characteristics were examined and developed predictive models. Analyzing these models, it is found that pulse current is the most significant parameter for both the responses, followed by pulse off time, gap voltage and pulse on time for MRR, and pulse on time and gap voltage for Ra. The model sufficiency is very satisfactory as the coefficient of determination (R2) is found to be greater than 98.3% and R2 adj is over 97.6%. These models can be used for selecting the values of process variables to get the desired values of the response parameters
Eye-controlled interfaces for multimedia interaction
No full textThe EU-funded MAMEM project (Multimedia Authoring and Management using your Eyes and Mind) aims to propose a framework for natural interaction with multimedia information for users who lack fine motor skills. As part of this project, the authors have developed a gaze-based control paradigm. Here, they outline the challenges of eye-controlled interaction with multimedia information and present initial project results. Their objective is to investigate how eye-based interaction techniques can be made precise and fast enough to let disabled people easily interact with multimedia information
