Applications of thermal energy storage to waste heat recovery in the food processing industry

A study to assess the potential for waste heat recovery in the food industry and to evaluate prospective waste heat recovery system concepts employing thermal energy storage was conducted. The study found that the recovery of waste heat in canning facilities can be performed in significant quantities using systems involving thermal energy storage that are both practical and economical. A demonstration project is proposed to determine actual waste heat recovery costs and benefits and to encourage system implementation by the food industry

Wheeler-DeWitt equation and Lie symmetries in Bianchi scalar-field cosmology

Lie symmetries are discussed for the Wheeler-De Witt equation in Bianchi Class A cosmologies. In particular, we consider General Relativity, minimally coupled scalar field gravity and Hybrid Gravity as paradigmatic examples of the approach. Several invariant solutions are determined and classified according to the form of the scalar field potential. The approach gives rise to a suitable method to select classical solutions and it is based on the first principle of the existence of symmetries.Comment: 17 page

The Relationship between Classroom Distractions and Off-Task Students

This study focuses on the prevalence of classroom distractions in elementary education candidates’ field experiences. Classroom disturbances challenge students’ ability to focus on, and process the information that is being taught (Frisby, et al. 2018). Disturbances can occur for a variety of reasons. Intentional distractions, or anti-citizenship behaviors are classroom disturbances that are created by students with the goal of distracting others (Myers, et al. 2015). Classroom disturbances can also be unintentional, yet still equally distracting. Throughout the duration of this research, the candidates have conducted observations and research in a variety of grade levels. In this paper, the candidates will compare and contrast their findings from each segment of time spent in the field, including COVID-19 data. From this comparison, the candidates will make note of similarities and their relevant significance from the research. The insights gleaned from this study have implications for all elementary teachers. By limiting the possible sources of distraction, teachers can more readily improve students’ focus, attention, and their overall engagement

Analiza nastanka grešaka u zasićenim kompozitnim metalima u lijevanom stanju

In research into the porosity of casts from metal saturated composites there is a need to identify the pores. Problems encountered here are connected with the following: - the difficulty in differentiating the pores from other structure components of materials, - the necessity of differentiating the porosity types resulting from non-saturation, gas occlusion and gas emission during coagulation and contraction of the matrix. The report presents research results conducted to identify the pores by means of computer image analysis with the application of an analyzing scanning computer.U istraživanju poroznosti na ljevovima metala od zasićenih kompozita postoji nužnost određivanja poroznosti. Prolemi koji se ovdje susreću su povezani sa slijedećim: - teškoćama u razlikovanju pora od drugih strukturnih sastavnica materijala; - potreba za razlikovanjem vrsta poroznosti zbog nezasićenosti plinske poroznosti i emisijom plinova tijekom zgrušavanja i stezanja matrice. Izvješće predstavlja rezultate istraživanja provedenog radi određivanja pora kompjutorske analize slike uz primjenu kompjutorskog skenera za provođenje analize

Technical Design Report for the PANDA Solenoid and Dipole Spectrometer Magnets

This document is the Technical Design Report covering the two large spectrometer magnets of the PANDA detector set-up. It shows the conceptual design of the magnets and their anticipated performance. It precedes the tender and procurement of the magnets and, hence, is subject to possible modifications arising during this process.Comment: 10 pages, 14MB, accepted by FAIR STI in May 2009, editors: Inti Lehmann (chair), Andrea Bersani, Yuri Lobanov, Jost Luehning, Jerzy Smyrski, Technical Coordiantor: Lars Schmitt, Bernd Lewandowski (deputy), Spokespersons: Ulrich Wiedner, Paola Gianotti (deputy

White Paper and Roadmap for Quantum Gravity Phenomenology in the Multi-Messenger Era

The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put to test. The dawn of multi-messenger high-energy astrophysics has been tremendously beneficial, as it allows us to study particles with much higher energies and travelling much longer distances than possible in terrestrial experiments, but more progress is needed on several fronts. A thorough appraisal of current strategies and experimental frameworks, regarding quantum gravity phenomenology, is provided here. Our aim is twofold: a description of tentative multimessenger explorations, plus a focus on future detection experiments. As the outlook of the network of researchers that formed through the COST Action CA18108 "Quantum gravity phenomenology in the multi-messenger approach (QG-MM)", in this work we give an overview of the desiderata that future theoretical frameworks, observational facilities, and data-sharing policies should satisfy in order to advance the cause of quantum gravity phenomenology
