Influences of Chemical Functionalities on Crystal Structures and Electrochemical Properties of Dihydro-benzoxazine Dimer Derivatives
2021
Dihydro-1,3,2H-benzoxazine dimer derivatives or dihydro-benzoxazine dimers are a class of compounds typically prepared by ring-opening reactions between dihydro-benzoxazines and phenols. Dihydro-benzoxazine dimers act as chelating agents for several transition and rare-earth cations. To better understand the chelating properties, it is necessary to examine their structural features and electrochemical characteristics thoroughly. However, the electrochemical properties of dihydro-benzoxazine dimers have not been tremendously examined. Herein, eight derivatives of dihydro-benzoxazine dimers possessing different substituents on the benzene ring and the tertiary-amine nitrogen were synthesized …
A version of Hake’s theorem for Kurzweil–Henstock integral in terms of variational measure
2019
Abstract We introduce the notion of variational measure with respect to a derivation basis in a topological measure space and consider a Kurzweil–Henstock-type integral related to this basis. We prove a version of Hake’s theorem in terms of a variational measure.
University Faculty Perception of Cyber-Plagiarism: A Virtual Discussion Group
2021
Resumen Este estudio analiza el ciberplagio académico desde la perspectiva del profesorado del Grado en Traducción e Interpretación de la Universidad Internacional de Valencia. Dado que se trata de una práctica fraudulenta cada vez más extendida en las aulas universitarias, se hace necesario que el cuerpo docente reflexione sobre ella para evitar que se convierta en un recurso estructural por parte del alumnado en este nivel educativo. El estudio apuesta por una metodología cualitativa y, en concreto, el grupo de discusión, el cual se lleva a cabo por videoconferencia gracias a la participación de su claustro (n=16). Como instrumento se diseña un guion de seis preguntas a partir de las cual…
Non-linear optical, electrochemical and spectroelectrochemical properties of amphiphilic inner salt porphyrinic systems
2016
Three zwitterionic meso-substituted A3B- and AB2C-porphyrins containing one sulfonato alkylpyridinium substituent and three or two alkoxy-substituted phenyl groups were synthesized in good yield and fully characterized as to their physicochemical properties by a variety of techniques. This new series of inner salt donor-acceptor meso-substituted porphyrin derivatives were prepared for possible application as amphiphilic probes for membrane insertion in the area of combined second-harmonic and two-photon fluorescence cellular microscopy. To this end, the linear and nonlinear optical properties of the compounds were characterized, together with their electrochemical and spectroelectrochemica…
The significance of student voice: female students’ interpretations of failure in Tanzanian secondary education
2014
Abstract: In Tanzania, the national examinations are used as the primary tools for selection and transition from lower to upper secondary education. Female students are more likely to fail in the national exams and to drop out from education. This article examines the perspectives of female students concerning their advancement in secondary education. Two sets of qualitative data, responses to a research questionnaire from 100 female lower secondary school students and follow-up interviews with seven mature students enrolled in a non-formal school who had failed in the national examinations, were analysed to identify critical issues influencing the educational advancement of female students…
Digital rights management : blockchain and digital music content management
2017
Tämän tutkielman tarkoituksena oli ymmärtää lohkoketjuteknologian vaikutuksia digitaalisen musiikin sisällönhallintaan hyödyntäen digitaalisten tekijänoikeuden hallintajärjestelmien (DRM) viitekehystä. Tutkielma sisälsi kolme tutkimuskysymystä: mitä digitaalisia tekijänoikeuden hallintajärjestelmien haasteita lohkoketjuteknologia voisi mahdollisesti ratkaista verrattuna edellisiin DRM-teknologioihin, miten lohkoketjuteknologia liittyy DRM:n aiempiin teknologisiin haasteisiin ja mitkä ovat lohkoketjuteknologian mahdolliset vaikutukset digitaalisen musiikin tekijänoikeuden hallintajärjestelmiin. Vastaukset tutkimuskysymyksiin perustuivat kirjallisuuskatsaukseen sekä puolistrukturoituihin teem…
Prowadzenie działalności gospodarczej jako podstawa wygaśnięcia mandatu radnego w świetle orzecznictwa sądowoadministracyjnego – wybrane problemy
2020
W pracy przedstawiono podstawy prawne wygaszania mandatu radnego, pochodzącego z wyborów powszechnych, w sytuacji stwierdzenia prowadzenia przez niego działalności gospodarczej na mieniu czy też z wykorzystaniem mienia gminy, w której uzyskał mandat. Zaprezentowano stanowiska sądów administracyjnych wyrażone w tym przedmiocie wskutek skarg na uchwały lub rozstrzygnięcia nadzorcze, mocą których wygaszono mandat radnego z uwagi na przesłankę prowadzenia działalności gospodarczej
“To Own, or not to Own?” A multilevel analysis of intellectual property right policies' on academic entrepreneurship
2017
The political environment around universities has led them to create an infrastructure to manage academic inventions. While some consider that the advantages of a university entrepreneurial structure outweigh any potential negative effects, others question their detrimental effect on academic scientists’ entrepreneurial behavior. However, this debate remains unresolved as none of these two views have been fully empirically supported. Using multilevel models for a population of 2230 professors in 27 universities in Canada (82 individuals per unit on average), we test the effect of three features of institutional intellectual property right policy characteristics, namely, property rights (own…
EXPLORING THE OBSTACLES OF LATVIAN FOOD COMPANIES EXPORT TO CHINA
2016
As we know, China is the biggest trader in the world. European Commission has revealed that China has become the European Union (EU)`s second largest trading partner behind the United States, and EU is China`s biggest trading partner. This situation just proves the necessity of making good partnership with China, which is especially needed for such a small country as Latvia. The main export fields for Latvia are wood, metal, electrical devices and minerals. As the population of China is growing very fast, leading to more than one billion people in 2016 (increased for more than 41 million in last six years), the food market is in need of more and more products. Of course, Chinese market may …
Los procedimientos civiles para recuperar la posesión de inmuebles ocupados
2021
The purpose of this article is to analyse the differnt civil process of the Civil Procedure Law that can be used for the recovery of illegally occupied properties: eviction for precarious, injunction to recover possession and action action for the protection of registered property rights. Special attention is paid to the new procedure of rapid recovery of possession that has been created by Law 5/2018 amending the classic injunction to regain possession.
