Turnīru rezultātu reģistrācijas sistēma spēlei League of Legends
2019
Kvalifikācijas darba ietvaros ir izstrādāta turnīru rezultātu reģistrēšanas sistēma spēlei “League of Legends”, kas paredz iespēju reģistrēt spēles turnīru administratoriem informāciju par dažādiem turnīriem un to norises rezultātiem, kā arī dot iespēju pašiem turnīru dalībniekiem un citiem cilvēkiem sekot līdzi turnīru norisei. Konkrētā sistēma palīdzēs ne tikai vien visiem, kam interesē kāds turnīrs un tā iznākums, apskatīt svarīgākos turnīra aspektus, neatrodoties tieši paša turnīra norises vietā, bet vēl jo vairāk pašiem turnīru organizatoriem taupīt laiku un naudu, ērti un ātri reģistrējot nozīmīgākos turnīra datus sistēmā, netērējot tam nekādus papīra resursus, kas mēdz ātri kļūt neli…
Moral Neuroeducation, Ethics of Justice and Pluralism
2019
In order to design a model of moral neuroeducation for pluralistic and democratic societies three core issues need to be addressed in-depth: firstly, the cerebral basis of moral behaviour (neuroethics); secondly, how neuroscientific knowledge can be engaged in the teaching of moral education (moral neuroeducation); and finally, the specific ethical model underpinning this area of education (moral and political philosophy). The last of these three issues is the focus of this chapter, as it is fundamental to the whole project of moral neuroeducation, and it structures the approach to moral neuroeducation proposed in this chapter. Drawing on the conceptual framework of Adela Cortina’s ethics o…
Cubic metamaterial crystal supporting broadband isotropic chiral phonons
2021
Chiral metamaterials can support chiral phonons leading to acoustical activity, the acoustical counterpart of optical activity. However, the properties of early metamaterial designs have been very highly anisotropic, and chiral acoustical phonons occurred only for selected high-symmetry directions. The authors propose a novel chiral metamaterial based on ``twisting'' a truncated octahedron in a simple-cubic unit cell. Not supported by crystal symmetry alone but rather by a tuned degeneracy, chiral phonons and large broadband acoustical activity are obtained for all phonon propagation directions in 3D. This result is notable because even isotropic achiral acoustical phonons are rare for crys…
Uranyl ion complexes with aminoalcoholbis(phenolate) [O,N,O,O′] donor ligands
2006
Abstract The reaction between uranyl nitrate hexahydrate and phenolic ligand precursor N,N-bis(2-hydroxy-3,5-dimethylbenzyl)-2-aminoethanol (H3L1) in acetonitrile without base affords the dinuclear uranyl complex [(UO2)2(H2L1)2(NO3)2] (1); in the presence of base, the mononuclear complex [UO2(H2L1)2] · 2H2O (2) is formed. Ligand N,N-bis(2-hydroxy-5-t-butyl-3-methylbenzyl)-2-aminoethanol (H3L2) affords a uranyl complex of formula [UO2(H2L2)2] · 2CH3CN (3); ligand N,N-bis(2-hydroxy-3,5-dimethylbenzyl)-3-amino-1-propanol (H3L3) affords a uranyl complex of formula [UO2(H2L3)2] (4); whilst ligand N,N-bis(2-hydroxy-5-t-butyl-3-methylbenzyl)-3-amino-1-propanol (H3L4), used as the hydrochloride, af…
Everyday Family Life and Multiple Roles of the Female Doctoral Students
2017
Combining work and family life, and the challenges and solutions connected to it is a topical and globally significant subject. In the article I examine how the under 40-year-old female doctoral students with a family succeed in combining their roles as a mother and a doctoral student in their own everyday lives. A number of large and simultaneous challenges condense in the everyday life of an under 40-year-old female doctoral student with a family. In the examination I concentrate on the everyday challenges of the female doctoral student, on the interface of the family and the doctoral studies and on the choices made in everyday life. The qualitative research material consisted of the them…
Electrochemically-driven conformational shift in mono- and di-copper constrained macrotricyclic cyclen receptors
2008
International audience; An electrochemical study of mono- and di-copper constrained cyclen macrotricycles is presented. Electrochemical data in DMF solution indicate that the reduction of dinuclear complexes occurs in two steps in the -0.4 to -0.8 V vs.AgCl/Ag potential range yielding CuII CuI and CuI CuI species further reduced to Cu metal at highly negative potentials. Mononuclear complexes are reduced in two steps to CuI and Cu metal. Electrochemical data suggest that reduction of both mononuclear and dinuclear complexes approach a square scheme involving electrochemically-driven conformational shifts for metal ions. The presence of endo- and exo-forms of the complexes are revealed by ch…
Choroidal osteoma with choroidal excavation and associated neovascular membrane: An OCT-angiography study.
2017
Abstract Clinical case A case is presented of a unilateral choroidal osteoma with choroidal excavation and associated neovascular membrane that was studied using OCT-angiography. The OCT and OCT-angiography revealed an area of choroidal excavation and an active neovascular membrane. Three doses of aflibercept were administered to the patient, which stabilized the neovascularisation. Discussion OCT-angiography was used to analyze the morphology of the superficial vascular network of the osteoma, as well as to monitor the evolution of the neovascular membrane.
Flow injection-chemiluminescence determination of octyl dimethyl PABA in sunscreen formulations
2002
Abstract A sensitive flow injection (FI) procedure was developed for the determination of the UV-filter octyl dimethyl PABA in sunscreen formulations based on its chemiluminescence (CL) induced by potassium permanganate in sulfuric acid. Both second-order and log–log calibration graphs can be used to perform the analysis. Ninety injections per hour can be carried out, which means a sample throughput of 18 h −1 if five injections per solution are performed. The limit of detection (3 σ ) was 25 ng ml −1 . The interference effects of the excipient and other UV filters are studied. Sunscreen formulations containing octyl dimethyl PABA were analysed by both the proposed FI-CL method and a liquid…
Bericht zum 1. Workshop zur lokalen Exzision von Rektumkarzinomen
2007
To determine the significance of local excision (LE) of rectal cancer and discuss oncologic results, a 1st Workshop on LE of rectal cancer was held at the Department of General und Abdominal Surgery, Johannes Gutenberg-University Mainz, Germany. The option of broadening the indication for local excision after neoadjuvant radiochemotherapy (nRCT) of rectal cancer was to be assessed. Local excision of "low risk" T 1 carcinomas was rated as oncologically adequate therapy with good functional results and low complication rates. Transanal endoscopic microsurgical (TEM) resection was the preferrred technique. Pre-requisite for the achievement of low recurrence rates (5 %) is an R0 resection with …
Laparoscopic neuromapping in pelvic surgery: scopes of application.
2013
Background. New developments in intraoperative electrophysiological neuromonitoring for conventional surgery are providing further insights into functional neuroanatomy and nerve-sparing in the minor pelvis. The aim of this study was to open up potential scopes of application in laparoscopy. Methods. Ten patients with different indications for surgery (presacral tumor excision, n = 2; resection rectopexy. n = 2; low anterior rectal resection, n = 2; proctocolectomy. n = 2; abdomino-perineal excision of the rectum, n = 2) were investigated prospectively. The pelvic autonomic nerves were bilaterally mapped by laparoscopic electric stimulation under simultaneous electromyography of the intern…
