A fatal iatrogenic right vertebral injury after transoral odontoidectomy and posterior cervical stabilization for a type II odontoid fracture.
2014
Abstract The authors present a singular case of an iatrogenic right vertebral artery injury, involving a 67 year-old man, who reported a type II odontoid fracture (Anderson and D'Alonzo Classification) and posterior atlantoaxial dislocation following a road traffic accident. A small injury involving the right vertebral artery occurred as a consequence of transoral odontoidectomy and posterior cervical stabilization. It was caused by bone spicules of spinal origin and their presence was confirmed by the histological section of the right vertebral artery at the level of C1–C2. The case confirms how iatrogenic vertebral artery injuries during cervical spine surgery may be potentially lethal, e…
Collisional shifting and broadening coefficients for the rovibrational anisotropic lines of the ν1/2ν2 fermi dyad in CO2 gas studied by stimulated Ra…
1998
High-resolution stimulated Raman spectroscopy was applied to the study of collisional broadening and shifting for rovibrational anisotropic Raman lines of the Fermi dyad of molecular carbon dioxide. The O(J) lines of the ν1 band and the S(J) lines of the 2ν2 band were recorded at 295 K. The pressure-induced line shifts were obtained and compared with the overall shift of the high-density Raman Q-branch. A rotational quantum number dependence of the rovibrational line broadening coefficients was observed. The experimental line broadening coefficients were used in order to check the ability of two theoretical methods (random phase approximation and sum rule) for calculating the line broadenin…
"Though It Be but Little, It Is Fierce": Excited State Engineering of Conjugated Organic Materials by Fluorination.
2016
Fluorination is frequently used to significantly change the properties of conjugated organic materials due to fluorine’s exceptional properties; well-known is its impact on electronic structure, but it also impacts the geometry despite fluorine’s small size. Less known, the changes in the electronic and geometrical properties may provoke drastic changes of the excited state properties like batho- and hypsochromic shifts of absorption and emission bands (inter alia leading to excited state switching), hypo- and hyperchromic effects, spectral broadening, and changes of the nonradiative deactivation pathways. The state of the art on these issues is summarized in the current Perspective to stim…
Eiropas Savienība un Ķīnas Jaunā Zīda Ceļa Iniciatīva: iespējas un izaicinājumi
2017
Jaunā Zīda Ceļa Iniciatīva, kuru 2013. gadā ierosināja Ķīna ar galveno mērķi savienot lielākās Eirāzijas ekonomikas, izmantojot infrastruktūru, tirdzniecību un investīcijas. Šī ir lielākā un nozīmīgākā Ķīnas ekonomiskā stratēģija 21. gadsimtā, kura tieši ietekmēs ES un it īpaši Centrāleiropas un Austrumeiropas valstis. Šobrīd Eiropas Savienībā ir daudz neatrisinātu, attīstību kavējošu faktoru kā nelīdzsvarots attīstības līmenis starp tās dalībvalstīm, finanšu krīzes atskaņas, grūti prognozējama bēgļu un nelegālās migrācijas situācija, pasliktinātas attiecības ar Krieviju, Breksits, un nenoteiktība ar TTIP tālāko attīstību, ņemot vērā jauno ASV valdību. Pēc autora domām, Ķīnas kompānijām pie…
Intellectual Structure of the Belt and Road Initiative Research: A Scientometric Analysis and Suggestions for a Future Research Agenda
2020
China’s Belt and Road Initiative (BRI) has attracted increasing attention worldwide since its inception in 2013. Although the research is fast increasing in terms of publications, there is a lack of knowledge about the intellectual structure, research trends, and appropriate theories underpinning. Using bibliometric data from 1583 articles from 2013 to 2019 in the Web of Science and Scopus databases, we used bibliometric techniques and scientometric analyses to identify and analyze the intellectual structure, hotspots, and emerging trends in this field. We identified 18 clusters that we categorized into three groups for thematic discussion. Research gaps and future research directions were …
Development of “New Silk Road” Northern Branch through Seaport of Riga in Latvia
2014
Abstract The study reveals opportunity to develop the “New Silk Road” Northern branch from North-West China (the People's Republic of China) via seaport of Riga in Latvia to Europe. The methods of the study are the monographic method, the statistical analysis, the expert method and a case study. The study shows that the shortest route for the “New Silk Road” Northern branch is through seaport of Riga (Latvia) which is the shortest way from China to the seaport in the European Union. The existing railway infrastructure can be used from Urumqi (North-Western China) to the seaport of Riga. Transit countries for this route are Kazakhstan and Russia. This route could be beneficial for distributi…
Using Chinese in China - challenges and opportunities : a case study of three Finnish sojourners
2016
Despite the growing attention on interaction between language learners/sojourners and host community, there has been little research on second language (L2) using experience by adopting case study approach, by which each individual’s voice is valued. Grounded in sociocultural theory (SCT), the present study explores challenges and opportunities of international sojourners when they use Chinese in China by investigating three Finnish sojourners’ experiences in using Chinese. Coleman’s concentric circles model is adopted to illustrate sojourners’ different language choices and reasons with compatriots, international people and host community. Narratives and interview data are analyzed and dis…
Chromatographic Efficiency in Micellar Liquid Chromatography: Should it Be Still a Topic of Concern?
2013
Micellar liquid chromatography (MLC) was first proposed as an attractive alternative to avoid the use of organic solvents. It was soon apparent that pure micellar solutions yield poor efficiencies. This problem was remediated by the addition of a small amount of an organic solvent. However, the general opinion of the poor peak shape has prevailed as a handicap for MLC, in spite of the fact that the hybrid mode often offers similar or even improved efficiencies (for basic compounds) relative to that attained in the hydro-organic mode. Only the efficiencies for apolar non-ionizable compounds are still clearly inferior. This work describes the type of interactions and polarity changes with org…
Characteristic Topological Features of Promoter Capture Hi-C Interaction Networks
2020
Current Hi-C technologies for chromosome conformation capture allow to understand a broad spectrum of functional interactions between genome elements. Although significant progress has been made into analysis of Hi-C data to identify the biologically significant features, many questions still remain open. In this paper we describe analysis methods of Hi-C (specifically PCHi-C) interaction networks that are strictly focused on topological properties of these networks. The main questions we are trying to answer are: (1) can topological properties of interaction networks for different cell types alone be sufficient to distinguish between these types, and what the most important of such propert…
VoiP performance analysis in IEEE802.16 networks
2012
WiMAX, as known as IEEE standard 802.16, is a wide range broadband wireless access network which has a significant good support for the quality of service. According to IEEE standard 802.16e WiMAX has support also for mobility. One of the key advantages of the WiMAX network is the possibility to assign QoS parameters as connection based. A good example of traffic type having strict QoS demands is VoIP. VoIP will probably be a killer application in the future's broadband wireless networks because of its cost efficiency compared to circuit switched networks. In this paper, we analyze by extensive simulations how QoS is applied per connection, especially for the VoIP connection.
