Detection and Mapping of Water Quality Variation in the Godavari River Using Water Quality Index, Clustering and GIS Techniques

Author(s): Indrani Gupta, Awkash Kumar, Chandrakant Singh, Rakesh Kumar

Abstract
The objective of this research is to develop a tool for planning and managing the water quality of River Godavari. This is achieved by classifying the pollution levels of Godavari River into several categories using water quality index and a clustering approach that ensure simple but accurate information about the pollution levels and water characteristics at any point in Godavari River in Maharashtra. The derived water quality indices and clusters were then visualized by using a Geographical Continue reading

A New Method of Estimating Wave Energy from Ground Vibrations

Author(s): K. Ram Chandar*, V. R. Sastry

ABSTRACT

Performance of explosive energy is rated in a number of ways, obtained either from theoretical calculations or from experimental tests. However, it is difficult to determine the amount of the explosive energy transferred to the rock and converted into efficient work in the application of rock blasting. Although measurement of some of the effects of explosive energy in rock mass is ground vibration, noise, etc., which are usually Continue reading

Electric Vehicles Analysis inside Electric Mobility Looking for Energy Efficient and Sustainable Metropolis

Author(s): Miguel Edgar Morales Udaeta, Carolina Attas Chaud, André Luiz Veiga Gimenes, Luiz Claudio Ribeiro Galvao

ABSTRACT
This paper aims to study and evaluate electric mobility over time, focusing on the development of the electric car. Methodologically, in order to accomplish this intent, the characterization of the electric vehicle (EV) is made based on the variables which determine its performance, such as: assessment of speeds, distance traveled, analysis of facts related to the energy source (electro-chemical accumulators) and analysis of the determining system of electric mobility (the electric engine as a function Continue reading

The Third Polarization of Light

Author(s): Richard A. Hutchin

Abstract

A SQUID (Superconducting Quantum Interference Device) measures the magnetic flux inside the loop using the voltage across a pair of Josephson junctions. The signal goes through one oscillation every magnetic flux quantum (h/2e) and is the most sensitive magnet field detector in the world. It measures the magnetic flux even when no magnetic or electric field touches any part of the circuit.
A SQUID (Superconducting Quantum Interference
Device) measures the magnetic flux inside the loop using the voltage across a pair of Josephson junctions. The signal goes through one oscillation every magnetic flux quantum (h/2e) and is the most sensitive magnet field detector in the world. It measures the magnetic flux even when no magnetic or electric field touches any part of the circuit.

We are all taught that there are only two polarizations of light because Maxwell’s equations only support two polarizations. This is mathematically true for the electromagnetic fields, but we have learned since the days of Maxwell that the “real” electromagnetic field is not the electromagnetic field tensor Fμv (composed of Electric and Magnetic field terms) but rather the electromagnetic vector potential Aμ. When considered carefully, this requires a third polarization of light with very unusual properties. This third polarization of light does not generate electric or magnetic fields but should be detectable by its impact on supercurrents or quantum interference. It is also unavoidable since it automatically appears under Lorentz transformations to different moving frames. Continue reading

3D Geology Modeling from 2D Prospecting Line Profile Map

Author(s): Qing-Yuan Li1,2,3, Yang Cui2, Chun-Mei Chen3, Qian-Lin Dong3, Zi-Xiang Ma

Abstract

(a)
(a)

Using prospecting line profile map in combination with drilling and other information for 3D reconstruction of geological model is an important method of 3D geological modeling. This paper discusses the theory and implementation method of 2D prospecting line map into 3D prospecting line map and then into 3D model. The authors propose that it needs twice upgrading dimension to reconstruction 3D geology model from prospecting line profile map. Continue reading

The Development of LISTEN: A Novel Intervention for Loneliness

Author(s):Laurie A. Theeke, Jennifer A. Mallow

ABSTRACT
Purpose: The purpose of this paper is to present the development of LISTEN (Loneliness Intervention using Story Theory to Enhance Nursing-sensitive outcomes), a new intervention for loneliness. Methods: LISTEN was developed using the Medical Research Council (MRC) framework for intervention development. Extensive literature review revealed that belonging, relating, place in community, challenges, and meanings of coping were concepts significant to loneliness. Past interventions were limited but it was determined from a recent meta-analysis Continue reading

A Change in Bathing Style May Improve Mental Fitness

Author(s): Takaaki Kubo, Tomonori Yasuda, Yoshihisa Masumitsu, Yoshihiro Iwashita, Satoshi Watanabe, Taichi Ishizawa, Mitsuo Tsunakawa, Shingo Yano, Junichi Iimaya

ABSTRACT
Frequent bathtub bathing (BB) improves the mental health of middle-aged and older Japanese in-dividuals. This study investigated the chronic mental health effects of BB, maintaining warmth using an insulating sheet and sleeping bag after bathtub bathing (BBW), and bathtub bathing with herbal extracts (BBH) in healthy young adults. The study involved healthy young adults who habitually showered, as opposed to bathing. In the first experiment, 18 participants were randomly assigned to either the BB or BBW groups for 14 consecutive nights. After a 2-week washout period Continue reading

Effects of Irradiation with Light of Different Photon Densities on the Growth of Young Green Barley Plants

Author(s): Tianxiao Meng, Eriko Nakamura, Nobuto Irino, Khem Raj Joshi, Hari Prasad Devkota, Shoji Yahara, Ryuichiro Kondo

ABSTRACT

Effect of four light sources on the morphology of roots in young green barley. (a) ASL 200; (b) ASL 300; (c) R4:G1:B1 200; (d) R9:B1 200 (μmol mL−2·s−1).
Effect of four light sources on the morphology of roots in young green barley. (a)
ASL 200; (b) ASL 300; (c) R4:G1:B1 200; (d) R9:B1 200 (μmol mL−2·s−1).

In recent years, young green barley has been increasingly used as a functional food ingredient. Studies have shown that cultivated young green barley has different levels of amino acids, vitamin C, and polyphenol content depending on the harvest time. Furthermore, some studies have investigated the effect of the growing conditions on cultivated barley in particular the use of light-emitting diodes (LED). Young green barley was exposed to three light sources of different wavelengths (sun light [ASL], light-emitting diode[LED] – Red 9 + Blue 1 [LED-R9:B1], LED – Red 4 + Green 1+ Blue 1 [LED-R4: G1:B1]). Under light with photon densities of 200 μmolmL-2·s-1, the dry weight of young green barley was not affected, while the Continue reading

The Unemployment Volatility Puzzle: A Note on the Role of Reference Points

Author(s): Vincent Boitier

Abstract
This theoretical note aims at studying the role of reference points in generating unemployment volatility. For this purpose, I introduce the notion of reference points in a standard Mortensen- Pissarides model. I obtain two results. First, I find that the obtained model is similar to the one found by Pissarides in 2009. Second, I show that the introduction of reference points can increase significantly unemployment volatility through a mechanism à la Hagerdorn and Manovskii. Continue reading
