Status of Insect Pests and Natural Enemies of Direct Seeded and Transplanted Rice

Studies were conducted on the status of insect-pests and natural enemies of direct seeded rice (DSR) in comparison with puddled transplanted rice (PTR) during rabi and kharif in 2013-14. The rice leaf folder and yellow stem required both the seasons. Maximum leaf folder Cnaphalocrocis medinalis (Guenee) (13.03%) damage and yellow stem borer damage (13.49%) of white ears was recorded during last week of October and second week of November in DSR under unprotected situation respectively. While sucking pests population mainly green leafhopper incidence was comparatively high in PTR (3.29 and 4.92/hill) also plant hoppers incidence (BPH and WBPH) (28.90 and 18.44 adults/hill) under unprotected situation during two seasons respectively. Population of predators at both the season remained high throughout the study period in PTR than the DSR excep

Tangible Web Layout Design For Blind And Visually Impaired People

Although past research has enabled blind and visually impaired (BVI) developers to access information better and code more efficiently, they still lack accessible ways to create visual layouts. This research highlights the potential of using a tangible user interface (TUI) to enable BVI people to design web layouts, and presents Sparsha, a novel TUI for layout design. I conducted a semi-structured interview and a co-design session with a blind participant. Based on the elicited insights and designs, I implemented Sparsha using 3D-printed tactile elements, an Arduino-powered sensing circuit and a Web server that renders the final HTML layout. Users place tactile beads on a base to represent HTML elements on the screen. The Arduino senses the type and location of these beads and sends it to a web server which renders the correct HTML element in the correct location on the client browser, and provides audio feedback

Simulation of the Surface Topography on Laser Sintered Polymer Parts

One barrier of laser sintering (LS) to become the main process for Direct Manufacturing (DM) is the surface quality of LS parts. Hence, the property which has to be improved is the rough surfaces of LS parts due to the layered structure. Another additional effect is the incomplete melting of powder particles on the surface due to the high process temperature. In this paper we demonstrate our approach of a theoretical model for the topography of LS part surfaces. We investigated the surface roughness as a function of surface orientation. Considering that the model involves further variables as layer thickness, particle density and particle size distribution to describe the topography precisely. Experimental results were used to optimize and check the results of the model.Mechanical Engineerin

Anomalous cell sorting behavior in mixed monolayers discloses hidden system complexities

In tissue development, wound healing and aberrant cancer progression cell–cell interactions drive mixing and segregation of cellular composites. However, the exact nature of these interactions is unsettled. Here we study the dynamics of packed, heterogeneous cellular systems using wound closure experiments. In contrast to previous cell sorting experiments, we find non-universal sorting behavior. For example, monolayer tissue composites with two distinct cell types that show low and high neighbor exchange rates (i.e., MCF-10A & MDA-MB-231) produce segregated domains of each cell type, contrary to conventional expectation that the construct should stay jammed in its initial configuration. On the other hand, tissue compounds where both cell types exhibit high neighbor exchange rates (i.e., MDA-MB-231 & MDA-MB-436) produce highly mixed arrangements despite their differences in intercellular adhesion strength. The anomalies allude to a complex multi-parameter space underlying these sorting dynamics, which remains elusive in simpler systems and theories merely focusing on bulk properties. Using cell tracking data, velocity profiles, neighborhood volatility, and computational modeling, we classify asymmetric interfacial dynamics. We indicate certain understudied facets, such as the effects of cell death & division, mechanical hindrance, active nematic behavior, and laminar & turbulent flow as their potential drivers. Our findings suggest that further analysis and an update of theoretical models, to capture the diverse range of active boundary dynamics which potentially influence self-organization, is warranted

Comparative evaluation of bond strength of resin cements with and without 10-methacryloyloxydecyl dihydrogen phosphate (mdp) to zirconia and effect of thermocycling on bond strength ? An in vitro study

To compare bond strength of resin cements with and without 10-Methacryloyloxydecyl Dihydrogen Phosphate (MDP) to zirconia and evaluate effect of thermocycling on bond strength. Standardised test specimens were fabricated as per ADA specification 131. Ea

Moya Moya disease

Moya Moya disease is an entity, which represents chronic idiopathic non-inflammatory progressive occlusion of circle of Willis, which in course of time leads to development of collateral vessels. It is more common in Japanese individuals. This should be considered as a differential in young stroke. Here we present a case of 8-year-old young female with right hemiparesis and headache with a known history of seizure disorder

Improving maintainability of the battery storage system in electric aircrafts

11th International Conference on Through-life Engineering Services - TESConf2022 8-9 November 2022, Cranfield UKDue to the rising environmental awareness and fluctuating fuel prices over the past decade, several countries started collaborating on a national program to achieve the climate agreement goals of the Paris agreement. At the moment, one of the most crucial challenges of the electrification process is the replacement of conventional engines. As there is a substantial gap in energy density between fuel and batteries per unit volume, the consequence is increasing aircraft weight after electrification. The overall stability and configuration of the aircraft are affected by the altered weight, hence requiring further analysis. This paper focuses on discussing and proposing future solutions for the battery storage system in terms of maintainability and position in the aircraft. Methodology-wise, to validate the research solutions the paper uses a conventional aircraft planned to be retrofitted with a hybrid propulsion system as a case study. The results show that the battery system has to be separated into two main categories, namely the energy and structural storage system where the former concerns the selection of battery type and defining the battery size/ weight based on the required energy output and whereas the latter regards the positioning and structural design of the battery storage system.DMG Mor
