Synthesis, characterization, crystal structures and biological screening of 4-amino quinazoline sulfonamide derivatives
2019
Three quinazolin-4-ylamino derivatives containing phenylbenzenesulfonamides (7a-7c) were synthesized by reacting (E)-N'-(2-cyanophenyl)-N,N-dimethyl formamidine (6) with different 4- amino-N-(phenyl)benzenesulfonamides (4a-4c) and characterized by different techniques such as HRMS, IR, 1H NMR and 13C NMR spectroscopy. The structural properties were further examined by single crystal X-ray diffraction method. The X-ray data shows that compounds 7a and 7c contain two molecules and 7b contains one molecule in the asymmetric unit. Comparison of conformation of two distinct molecules, “A” and “B”, in the asymmetric unit of 7a and 7c were studied with the aid of reported literature. The in vitro …

Application Development from Prototype to Beta : A Case Study of the Application SeafarerCV
2018
Master's thesis Multimedia and Educational Technology MM500 - University of Agder 2018 When the prototype of a software product is completed and approved, development of a betaready resource is often the natural step toward a future final release. This process contains many steps that may prove vital to the eventual success or downfall of a future product. Technologies must be chosen, design methodologies must be followed, and care must be given to provide the final product with a solid foundation to build upon. This thesis follows such a development process for the development of resources for beta-testing. This process, as well as the human centered design approaches, and the resulting re…
Theoretical and experimental studies of some main group compounds : from closed shell interactions to singlet diradicals and stable radicals
2012
Acquiring knowledge of different interactions within and between molecules is a fascinating undertaking as it not only deepens our understanding of chemical bonding but also offers insight into electronic structures, molecular properties and the connections between these two. This dissertation combines together three main group chemistry related topics within the aforementioned theme. Research presented in the first third of this dissertation describes wave function and density functional theory studies of weak inter- and intramolecular interactions in pnictogen-based dimers X3Pn···PnX3 (Pn = N-Bi; X = F-I), dithallenes RTlTlR (R = H, Me, tBu, Ph) and octachalcogen dications Ch82+ (Ch = S, …
Type 1 Diabetes and Autoimmune Thyroid Disease—The Genetic Link
2021
Type 1 diabetes (T1D) and autoimmune thyroid disease (AITD) are the most frequent chronic autoimmune diseases worldwide. Several autoimmune endocrine and non-endocrine disorders tend to occur together. T1D and AITD often cluster in individuals and families, seen in the formation of autoimmune polyendocrinopathy (AP). The close relationship between these two diseases is largely explained by sharing a common genetic background. The HLA antigens DQ2 (DQA1*0501-DQB1*0201) and DQ8 (DQA1*0301-DQB1*0302), tightly linked with DR3 and DR4, are the major common genetic predisposition. Moreover, functional single nucleotide polymorphisms (or rare variants) of various genes, such as the cytotoxic T-lym…
Single-trial-based temporal principal component analysis on extracting event-related potentials of interest for an individual subject.
2023
Background: Temporal principal component analysis (tPCA) has been widely used to extract event-related potentials (ERPs) at group level of multiple subjects ERP data and it assumes that the underlying factor loading is fixed across participants. However, such assumption may fail to work if latency and phase for one ERP vary considerably across participants. Furthermore, effect of number of trials on tPCA decomposition has not been systematically examined as well, especially for within-subject PCA. New method: We reanalyzed a real ERP data of an emotional experiment using tPCA to extract N2 and P2 from single-trial EEG of an individual. We also explored influence of the number of trials (con…
Comparison between simulated and observed LHC beam backgrounds in the ATLAS experiment at E beam =4 TeV
2018
Results of dedicated Monte Carlo simulations of beam-induced background (BIB) in the ATLAS experiment at the Large Hadron Collider (LHC) are presented and compared with data recorded in 2012. During normal physics operation this background arises mainly from scattering of the 4 TeV protons on residual gas in the beam pipe. Methods of reconstructing the BIB signals in the ATLAS detector, developed and implemented in the simulation chain based on the FLUKA Monte Carlo simulation package, are described. The interaction rates are determined from the residual gas pressure distribution in the LHC ring in order to set an absolute scale on the predicted rates of BIB so that they can be compared qua…
Introducing evidence-based practices to manage problem behaviours at school: The behave application
2020
In the last years, an increasing awareness amongst educator and scholastic psychologists of the relevance to manage behavioural and emotional problems applying evidence-based approaches, and quasi-experimental designs is emerging. This request, however, must come to terms with certain barriers that persist in the school environment. The introduction of quantified methods to assess and monitor student's results, to evaluate the efficacy of the intervention, to understand the evolution of the single, is not part of the usual teacher's curriculum. The present paper describes the BEHAVE (Behavioral management model across Europe) application, a tool able to support the transition of all educato…
Connections Between Single-Level and Bilevel Multiobjective Optimization
2011
The relationship between bilevel optimization and multiobjective optimization has been studied by several authors and there have been repeated attempts to establish a link between the two. We unify the results from the literature and generalize them for bilevel multiobjective optimization. We formulate sufficient conditions for an arbitrary binary relation to guarantee equality between the efficient set produced by the relation and the set of optimal solutions to a bilevel problem. In addition, we present specially structured bilevel multiobjective optimization problems motivated by real-life applications and an accompanying binary relation permitting their reduction to single-level multiob…
Performance under Pressure on the Court: Evidence from Professional Volleyball
2018
This study analyzes how psychological pressure affects performance. It refers to the discussion on differences between choking, i.e., an acute performance decline under pressure and under- performance under pressure. When performance outcomes are not defined binary even slight performance decrements can have huge consequences for future career. To study the conse- quences of psychological pressure on performance, we employ data on the serving performance of 213 professional volleyball athletes in 226 matches. We do not find any evidence for the existence of severe performance decrements under pressure (i.e. choking). However, athletes serve less effectively under pressure, i.e., they serve …
