TL;DR: In this paper, a rare renal calculus with cystine and a common Ca-oxalate-apatite calculus was used to explore the applicability of these techniques.
Abstract: Micro-Raman and spatially resolved cathodoluminescence (CL) coupled to environmental electron microscope (ESEM) with energy dispersive spectrometry (EDS) are nondestructive techniques scarcely employed on renal calculi studies. This study used these techniques together with Electron Probe Micro-Analysis (EPMA), X-Ray diffraction (XRD), and Thermogravimetry (TG) to study a rare renal calculus with cystine and a common Ca-oxalate-apatite calculus in order to explore the applicability of these techniques. TG and XRD effectively determined the renal calculi, while ESEM and μ Raman provided useful information. The backscattering probe (BS) differentiates calculi with elements of dissimilar atomic masses such as P, S, and C. The authors inferred that the CL emission peaks at 325 (L-cystine-apatite) and 310 nm (Ca-oxalate) could be associated to oxygen hole center emission defects coupled with C—OH precursor bonds, while the CL spectral emission from the collagen proteins mask the hydroxyl-apatite spectra.

05 Jul 2018TL;DR: In this article, the authors explore the effects of Bitcoin (crude oil) and financial (equity, gold and stock prices) markets on the US dollar index, using a GJR-GARCH model to test these relationships for the period August 2010 to September 2016 using monthly data.
Abstract: The purpose of this paper is to explore the effects of Bitcoin (crude oil) and financial (equity, gold and stock prices) markets on the US dollar index. A GJR-GARCH model is used to test these relationships for the period August 2010 to September 2016 using monthly data. The results suggest that bitcoin gold and stock prices (DSJI) affect negatively and statistically significantly the returns of the US dollar index. There is also some evidence that there is asymmetry in the bitcoin market and its relation with the US dollar index and that the latter could be considered as a possible safe haven for gold, stock and bitcoin.

Abstract: Από τη μeλέτη των βομβίνων της Eλλάδος, έχουν δημοσιeυθeί από το 1995 και μeτά καταστάσeις των eιδών οι οποίeς eίχαν βασιστeί για τη σύνταξη τους σe δημοσιeυμένeς καταγραφές των eντόμων αλλά και σe πρωτογeνή συλλeγμένο υλικό. Η καταγραφή πληροφοριών σχeτικά μe τους βομβίνους στην Eλλάδα, eκτός των άλλων, eστιάζeται και στον eντοπισμό των καταγραμμένων μοναχά στη βιβλιογραφία eιδών για την eπιβeβαίωση της ύπαρξης τους μe νέeς πλέον καταγραφές. Στην προσπάθeια αυτή, πολλοί βομβίνοι συλλέχθηκαν και eξeτάστηκαν και σe ορισμένeς πeριπτώσeις καταγράφηκαν νέα για την Eλλάδα eίδη Bombus . Υπάρχουν όμως eίδη, κυρίως από παλιές βιβλιογραφικές πηγές, που δeν έχουν ξαναβρeθeί γeγονός που καθιστά την ύπαρξη τους ή μη στην σύγχρονη Eλλάδα ένα υπό έρeυνα αντικeίμeνο. Μe την eξέταση βομβίνων που συλλέχτηκαν κατά τα έτη 2006 και 2007 στον νομό της Φλώρινας προέκυψαν πρόσφατα πρωτογeνής πληροφορίeς για δύο eίδη «βιβλιογραφικών» βομβίνων, τα Bombus subterraneus (Linnaeus 1758) και Bombus cryptarum (Fabricius 1775). Βασίλισσα του B. subterraneus (που συλλέχτηκe 40°47´38N, 21°26´10E eπί Vicia cracca ) αναγνωρίστηκe χρησιμοποιώντας μορφολογικά χαρακτηριστικά και eργάτρια του B. cryptarum (που συλλέχτηκe 40°41´58,7N, 21°28´18,5E eπί Echium spp) καθορίστηκe μe μιτοχονδριακό DNA RFLP ανάλυση του CO1 γονιδίου. Οι νέeς αυτές καταγραφές βομβίνων από την πeριοχή του νομού Φλώρινας eπιβeβαιώνουν τη παρουσία των δύο eιδών Bombus στην Eλλάδα μeτά από πeρίπου 40 χρόνια και παρουσιάζονται στην παρούσα eργασία μe σχeτικά σχόλια.

17 Apr 2018TL;DR: The paper presents a learning environment built using the concepts explained as well as how this environment was used and evaluated in educational settings and showed that learners attained positive opinions regarding the interactive environment features and its effectiveness in learning.
Abstract: The use of online videos is a common practice today in education and this is evident from the abundance of free online courses that are delivered by universities, educational organizations as well as individual professionals. In most cases, the videos that exist in educational platforms are linear without any scope for interactivity and in cases where there is interactivity this is mainly restricted to in-video quizzes. The aim of this paper is to present ways for going beyond the standard invideo quizzes by augmenting videos with various interactive exercises and games that test learners' knowledge. Furthermore, the paper presents a learning environment built using the concepts explained as well as how this environment was used and evaluated in educational settings. The outcome of the evaluation showed that learners attained positive opinions regarding the interactive environment features and its effectiveness in learning.
