No full textMedicīnaVeselības aprūpeMedicineHealth CareVenovenozo ekstrakorporālo membrānu oksigenāciju (VV-EKMO) parasti izmanto kā pēdējo līdzekli akūta respiratorā distresa sindroma gadījumā. VV-EKMO lietošana pēdējo divdesmit gadu laikā ieverojami palielinājās, pēdējo 15 gadu laikā četrkāršojas. CESAR un EOLIA pētijumi, kā arī ELSO vadlīnijas spēja pārliecināt daudzus profesionāļus biežāk lietot EKMO, lai gan izdzīvošanas rādītāji būtiski neuzlabojās.32 VV-EKMO galvenā funkcija ir uzlabot skābekļa piegādi (DO2), DO2 efektivitāte ir labvelīgi saistīta ar izdzīvošanas rādītājiem. Šajā rakstā autori apskatīja dažādus pacientus un EKMO režīmus, saistītos faktorus, kas pozitīvi vai negatīvi ietekmē DO2 un patēriņu (VO2). Kā šobrīd ir skaidrs, DO2 efektivitāte lielā mērā ir atkarīga no dažādu EKMO komponentu sinhronizāciju ar pacienta elpošanu un sirdsdarbību. Autori izvirzīja hipotēzi, ka EKMO: MPMV (mākslīgā plaušu minūtes ventilācija): CO (sirds izvade) = 1:1:1 sinhronizācijas attiecība saistīta ar labāko DO2 līmeni atbilstoši pacientu vajadzībām. Ar šo tēmu saistītās zinātniskās literatūras apskatā bija skaidrs, ka CO un EKMO plūsmas sinhronizēšana uzlabo DO2, klīniskos rezultātus un dzīves kvalitāti. Nav veikts pietiekami daudz pētījumu par MPMV sinhronizāciju ar EKMO plūsmu vai CO, tāpēc tas joprojām ir turpmāko preklīnisko eksperimentālo un klīnisko pētījumu priekšmets.Venovenous Extracorporeal membrane oxygenation (VV-ECMO) is typically used as a last resort treatment in acute respiratory distress syndrome. VV-ECMO use has significantly risen over the last couple of decades, quadrupling in the last 15 years. CESAR and EOLIA trials as well as ELSO guidelines were able to convince many professionals to use ECMO more often although survival rates didn’t improve significantly.32 Primary function of VV-ECMO is to improve oxygen delivery (DO2), efficiency of DO2 is positively related to survival rates. In this article the author reviewed various patients and ECMO modes associated factors which positively or negatively affect DO2 and consumption (VO2). As it is clear by now, efficiency of DO2 is highly dependent on the synchronisation of various components of ECMO setup with patient's respiratory and cardiovascular system work. The author hypothesised that ECMO: ALMV (artificial lung minute ventilation): CO (cardiac output) = 1:1:1 synchronisation ratio associated with best - 100% DO2 rate according to patients' needs. In a review of scientific literature related to this topic it was clear that synchronising CO and ECMO flow improves DO2, clinical outcomes and quality of life. Not enough research has been made on synchronising ALMV with either ECMO flow or CO therefore it remains a subject for future preclinical experimental and clinical studies

Vladimir V. Lapin, Armiia Rossii v Kavkazskoi voine XVIII – XIX vv.
No full textVladimir Lapin’s Armiia Rossii v Kavkazskoi voine XVIII-XIX vv. (The Russian Army in the Caucasian War XVIII – XIX centuries) deals with the subject of the Russian involvement and conquest of the Caucasus in the course of 18th and 19th centuries. Unlike many traditional works on the subject the author does not present a chronological history of this conflict. Instead Lapin analyses the transformations the Russian Army underwent as a result of its prolonged interaction with the people and natu..
VV: Exploring Self-Love through a Second- Generation Lens
No full textThis Culminating Experience Project is a creative project consisting of a visual EP, titled ‘VV’. The purpose of creating this EP derives from the lack of South Asian representation in Western media, and the desire to utilize South Indian Classical music, more specifically Carnatic music, with popular music such as the RnB and Electronic genres. Utilizing information from cross-cultural studies, the EP thematically focuses on second-generation (the children of immigrants) identity and self-love. This project was multifaceted in nature and challenging as it required the author to engage in the following with limited prior experience: producing, songwriting, experimentation with hybrid recording techniques, electronic production, mixing, video production and editing and collaborating with others. The main body of work is a five-track EP, and features self-produced, self-written music that explores themes such as identity, heritage, mental health, and love in the context of navigating through two cultures as a second-generation British Asian immigrant. The music falls into the genre of Alternative RnB and Electronic music, but also feature elements of South Indian Classical music. To accompany the music, there are two music videos that illustrate the themes further. ‘VV’ requires further development, but nonetheless fills an evident gap within contemporary music.https://remix.berklee.edu/graduate-studies-production-technology/1138/thumbnail.jp
Subjective and objective quality assessment for volumetric video
No full textVolumetric video (VV) is a novel form of video that allows recreation of real-world scenes in 3D with users consuming the content from any viewpoint they desire. This makes VV best suited for augmented reality (AR) or virtual reality (VR) applications. This freedom necessitates increased user interaction with the VV itself, which brings new challenges to its visual quality assessment. In this chapter, various aspects of VV quality assessment using subjective user studies and objective quality estimation methods are discussed. These aspects include the manner of representing 3D models, mode of interaction, display settings (e.g., whether AR or VR headsets are used), rendering parameters, and how the characteristics of point clouds or meshes are used in quality estimation. The chapter discusses the advantages and disadvantages of different methods and provides take away messages for researchers.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Multimedia Computin
Paratransitive algebras of linear operators II
No full textIn this paper, the authors continue the analysis, first undertaken in Livshits et al. (2013) [2], of algebras AA of linear transformations on an n-dimensional complex vector space VV which have the property that if WW is a k-dimensional subspace of VV, then the image of WW under the action of the algebra AA intersects every m-dimensional subspace of VV. Here, we study the structure of such algebras under the stronger assumption that the image of WW under AA has codimension equal to m−1m−1 for all subspaces WW of dimension k in V

Il modello nel modello. Intertesti integrati nell’ Ilias Latina (vv. 611-613)
No full textThe article deals with a passage of the Latin Iliad (vv. 611-613) belonging to the
fight scene between Telamonian Ajax and Hector, which is strongly inspired by ovid’s
met. xiii. The intertextual analysis of the expression saxo sternere, absent in ovid, shows
a further allusion to 61-63 Ribb.2-3, which is recognized as one of ovid’s models. Trying
to emulate and surpass ovid, the author shows that the figure of Ajax, who is surprisingly
represented as Hector’s cousin, is long settled in the Roman literature
Conceptos médicos en Purgatorio XXV, vv. 37-78. Las virtudes y el desarrollo vital del feto.
No full textA passage from Divina Commedia (Purgatorio XXV, vv. 37-78) is analyzed that presents different reading problems, especially those related to doctrinal and medical aspects of medieval thought. Doctrinal problems are connected with the reception of the three animae (vegetative, sensitive and intellective souls) in the womb, and with the consequences derived from this fact. Medical problems are related to foetus’ formation, development and evolution, and to the adquisition of certain characteristics that determine its nature. This paper analyzes these problems, by comparing some relevant elements to fundamental texts of medieval medical knowledge, general science, Christian doctrine and other works by the same author
