Planar Hall effect in the Weyl semimetal GdPtBi

Observation of Weyl and Dirac Fermions in condensed matter systems is one of the most important discoveries. Among the very few available tools to characterize Weyl semimetals through electrical transport, negative magnetoresistance is most commonly used. Considering shortcomings of this method, new tools to characterize chiral anomaly in Weyl semimetals are desirable. We employ planar Hall effect as an effective technique in half Heusler Weyl semimetal GdPtBi to study chiral anomaly. This compound exhibits a large value of 1.5 mohm cm planar Hall resistivity at 2 K and in 9 T. Our analysis reveals that the observed amplitude is dominated by Berry curvature and chiral anomaly contributions. Through the angle dependent transport studies we establish that GdPtBi with relatively small orbital magnetoresistance is an ideal candidate to observe large planar Hall effect .Comment: Updated text

The Potential of Garden Cress (Lepidium sativum L.) Seeds for Development of Functional Foods

Garden cress (Lepidium sativum L.) belonging to Cruciferae family is widely grown in India, Europe, and United States. It has been used as an important medicinal plant since the Vedic era. Its seed, oil, and powder contain significant amount of protein, fat, minerals, fibers, and phytochemicals, which are incorporated in many functional beverages and foods. A number of clinical trials have been conducted on rats that also support the efficacy of garden cress seeds (GCSs). The seed of garden cress was used in the fortification of different food items but due to the lack of their physicochemical properties and medicinal value, the exploration of the potential of garden cress seed was limited. In the present review, we discuss the proximate chemical composition, physicochemical, medicinal properties, and the food product development with garden cress seed. The functional properties of garden cress seed stimulate us to review its different valuable properties and the fortified products developed by incorporating garden cress seeds

A Real-Time Approach for Smart Building Operations Prediction Using Rule-Based Complex Event Processing and SPARQL Query

Due to intelligent, adaptive nature towards various operations and their ability to provide maximum comfort to the occupants residing in them, smart buildings are becoming a pioneering area of research. Since these architectures leverage the Internet of Things (IoT), there is a need for monitoring different operations (Occupancy, Humidity, Temperature, CO2, etc.) to provide sustainable comfort to the occupants. This paper proposes a novel approach for intelligent building operations monitoring using rule-based complex event processing and query-based approaches for dynamically monitoring the different operations. Siddhi is a complex event processing engine designed for handling multiple sources of event data in real time and processing it according to predefined rules using a decision tree. Since streaming data is dynamic in nature, to keep track of different operations, we have converted the IoT data into an RDF dataset. The RDF dataset is ingested to Apache Kafka for streaming purposes and for stored data we have used the GraphDB tool that extracts information with the help of SPARQL query. Consequently, the proposed approach is also evaluated by deploying the large number of events through the Siddhi CEP engine and how efficiently they are processed in terms of time. Apart from that, a risk estimation scenario is also designed to generate alerts for end users in case any of the smart building operations need immediate attention. The output is visualized and monitored for the end user through a tableau dashboard

Management of Constipation through Yogasanas

Introduction: The word asana is originated by 'as' dhatu, which has two main meanings, a place to sit and a physical position. The place to sit refers to the place on which one sits such as Dari, Aasni, yoga mat etc. According to the Yoga Sutras, the name of a state of happiness with stability is asana. This is the most popular part of yoga. Ordinary people only consider this as yoga. Constipation is considered the mother of all diseases in Ayurveda. When the smooth form of faces of the body is not expelled after digestion, then this condition is called constipation. Purpose: To discuss the management of constipation through Yogasanas by clarifying it’s the identification and causes. Research Methodology: Data were collected by conducting an in-depth survey and study of Yogic traditional texts such as Yogasutra, Hathapradipika, Gheranda Samhita, Charaksamhita, Sushruta Samhita etc. and research papers related to the subject. Results: Although many groups of yoga asanas are helpful in the management of constipation, but the combined practice of the first three asanas, Tadasana, Tiryaka Tadasana and Katichkrasana, out of the five asanas performed in Shankhprakshalan, has been found to be quite beneficial in the management of constipation. By the practice of the above mentioned yogasanas, the peristalsis of the intestines becomes active, as a result of which, on the one hand, there is management of constipation and on the other hand, there is no possibility of constipation disease developing by the practice of the above mentioned yogasanas. Conclusion: For the management of constipation, the practice of Tadasana, Tiryak Tadasana and Katichkrasana along with its removal after studying the causes of the disease with precision is very useful

Fabrication of Low-Roughness Au/Ti/ SiO2/Si Substrates for Nanopatterning of 16-Mercapto Hexadecanoic Acid (MHA) by Dip-Pen-Nanolithography

Silicon based low-roughness Au/Ti/SiO2/Si substrates were fabricated using standard IC fabrication processes. Evolution of surface roughness during substrate fabrication process was studied. Fabrication process steps, namely, thermal oxidation and e-beam evaporation for ultra-thin Ti(~ 5 nm)/Au(22 nm) films, were optimized to result in surface r.m.s roughness ~ 0.2 m and ~ 1.0 nm, after thermal oxidation and Ti/Au deposition steps respectively. Surface roughness was estimated by atomic force microscope (AFM) imaging and image analysis. Nano-patterning experiments using thiol based 16-MHA molecular-ink on fabricated substrates were carried out, under controlled environment conditions, by dip-pen-nanolithography (DPN) technique. Minimum line-width ~ 60 nm and circular dots radius ~ 175 nm were patterned. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/2779

Magnetic field induced strong valley polarization in the three dimensional topological semimetal LaBi

LaBi is a three-dimensional rocksalt-type material with a surprisingly quasi-two-dimensional electronic structure. It exhibits excellent electronic properties such as the existence of nontrivial Dirac cones, extremely large magnetoresistance, and high charge-carrier mobility. The cigar-shaped electron valleys make the charge transport highly anisotropic when the magnetic field is varied from one crystallographic axis to another. We show that the electrons can be polarized effectively in these electron valleys under a rotating magnetic field. We achieved a polarization of 60% at 2 K despite the coexistence of three-dimensional hole pockets. The valley polarization in LaBi is compared to the sister compound LaSb where it is found to be smaller. The performance of LaBi is comparable to the highly efficient bismuth.Comment: 5 figure

A rare case of acute osteomyelitis in a 13-year-old with physeal involvement

Osteomyelitis of epiphyses in adolescents is a rare finding. We evaluate one such case in which high degree of clinical suspicion and prompt surgical intervention yielded good functional results. This is a case report of 13-year-old girl diagnosed with osteomyelitis of right knee. MRI is suggestive of physeal involvement. Physeal involvement makes the management very challenging. Surgical intervention was planned to reduce bacterial load and minimize possibility of damage to knee joint (articular cartilage and joint capsule). Lateral and posterior compartment of leg was decompressed, fibular osteotomy done, drilling in tibial epiphyseal and metaphyseal region of tibia done avoiding any injury to growth plate. Pus for culture and sensitivity and specific antibiotics started with monitoring of blood parameters for infection like ESR, CRP, TLC. Patient taken up for second debridement after one week of index surgery. After 6 weeks of intravenous antibiotic patient discharged in afebrile state with reduced values of blood parameters and acceptable range of knee movement. Lower extremity functional scoring (LEFS) of 45/80 i. e., 56.83 % at the end of 4 months. Good functional outcome at the end of 1 year. Early clinical suspicion with prompt investigation, surgical and medical management gives promising result
