Implicit large-eddy simulation of the stratocumulus-topped boundary layer: A grid sensitivity study
No full textA range of implicit large-eddy simulations of the stratocumulus-topped boundary layer is performed to study the influence of grid resolution on selected parameters including liquid water path and second and third moments of vertical velocity fluctuations. The simulations are based on two sets of aircraft measurements, which are also used to evaluate the results of the simulations. The specific case presented here indicates that simulations with a grid aspect ratio accounting for the anisotropic nature of the turbulence near the surface and at the top of the boundary layer lead to better agreement with measurements than simulations with an isotropic grid
Experimental application of a dynamic observer to capture and predict the dynamics of a flat-plate boundary layer
No full textThe recent approach, proposed by Guzman-Inigo et al. \cite{GuzmanInigo2014}, using System Identification to derive a Reduced Order Model from snapshots of a flow is applied to a transitional boundary layer growing over a flat-plate. It is shown that such an approach can indeed be applied to experimental PIV snapshots. Using a proper learning dataset and a proper local sensor, it is shown that the evolution of boundary layer can be properly estimated from the time evolution of the local probe and with no more than ten POD modes for the Reduced Order Model. The influence of the various parameters on the efficiency of the system identification technique is discussed

Semantic and Stylistic Potential of the Theonyms in the Strutsyuk`s J.G. Works about Kholmshchyna
No full textУ статті розглянуто функціонування теонімів у творах Й. Г. Струцюка про
долю холмщаків, виявлено їхні структурні, функціональні та семантичні особливості. Дослідження показало, що в художній спадщині волинського письменника вжито усталені найменування Бога, які в контексті набувають оригінальних конотацій. This article is dedicated to analysis the theonyms in the work of Volyn writer Strutsyuk J.G. This type of own names is distinguished by particularly expressiveness, as behind their referents appears complexes of philosophical and religious beliefs. In the investigation was examined the structural and semantical particularities of onyma God, and was found nominative, differential, localizing, emotional and allusive functions. The theonyms used in the work of J.G. Strutsyuk disclose the Christian worldview's fundamentals of the author and special by proper understanding of the religious experience of God. The results of the investigation showed that the style of this language units in the texts based on their traditional using in folk speech and confessional style
Hauntings – A nodalist study
No full textSince Deleuze and Guattari first described the concept of the rhizome as a model of cultural transmission in A Thousand Plateaus (1980), a new way of processing information in the Arts and Social Sciences has emerged – ‘Nodalism’. Philip Gochenour has convincingly argued that units of culture can now be thought of as ‘nodes’ existing in a nonhierarchical, web-like network. Information transfer between nodes in the network is horizontal, omni-directional and not necessarily teleological, a way of viewing the world which has been paralleled and actualized in the last twenty years by the emergence, growth and ubiquity of the internet and the World Wide Web.
The author – a developing audiovisual artist – here offers four videomusic pieces and one virtual sound-synthesis tool. At first glance, the pieces may appear to have little in common. However, the commentary will attempt to show that they are subtly linked together, immersed in a cocoon of rhizomatic, pluralistic, thread-like connections.
The strongest ‘thread’ holding them together appears to be the trope of being ‘haunted’ in some way – either by influence, genre, or overarching concept. However, this thesis will attempt to show how a detailed consideration of each piece results in a highly complex final picture in which the pieces can be thought of as individual cultural nodes suspended in a dense rhizomatic mass of lateral cultural threads. For the sake of completion, however, the project has received the name Hauntings in reference to one of the strongest shared tropes running throughout all five works
Invertebrados bentónicos marinos de la Antártida: ecología química, bioactividad y biodiversidad
No full text[spa] Esta tesis cubre diferentes aspectos de los invertebrados marinos bentónicos de la Antártida. Se trata de una tesis multidisciplinar presentada en formato artículos en la que se hacen las siguientes aportaciones: (i) por un lado se hace una revisión de los productos naturales de origen animal y vegetal descritos hasta Mayo de 2007 en las aguas de la Antártida. En dicha revisión se hace especial énfasis en el papel que juegan los productos naturales en el contexto de su ecosistema; (ii) se aportan también datos sobre experimentos de repelencia alimentaria en los que se utilizaron extractos lipofílicos de invertebrados bentónicos de 2 zonas muy poco estudiadas (este del Mar de Weddell e Isla de Bouvet). En dichos experimentos, que se llevaron a cabo utilizando depredadores simpátricos, se ha demostrado que algo más de la mitad de los invertebrados testados poseen defensas químicas que los defienden frente a posibles depredadores. En algunos de estos casos las defensas químicas parecen localizarse en las partes más expuestas/vulnerables de los organismos testados; (iii) uno de los artículos de esta tesis confirma el potencial antitumoral que tienen los invertebrados marinos bentónicos antárticos y sub-antárticos. Se trata del estudio antitumoral más grande que jamás se haya hecho en este área con resultados muy prometedores para phyla como Chordata, Porifera y Cnidaria, entre otros; (iv) por último se describen un total de 4 nuevas especies de anélidos poliquetos de las aguas someras de la Antártida. Dichos organismos pertenecientes a las familias Cirratulidae (1 especie del género Cirratulus), Dorvilleidae (2 especies del género Ophryotrocha) y Siboglinidae (1 especie del género Osedax), fueron descritos a partir de huesos de ballena colocados experimentalmente en las aguas de Isla Decepción (Islas Shetland del Sur). Estos hallazgos confirman la importancia que los huesos de ballena pueden tener en el contexto de las aguas de poca profundidad de la Antártida.[eng] The Thesis entitled “Antarctic marine benthic invertebrates: chemical ecology, bioactivity and biodiversity" covers different aspects related to Antarctic marine benthic invertebrates. This is a multidisciplinar thesis comprising several scientific papers making the following contributions: (i) on the one hand it revises the described Antarctic marine natural products derived from animals and algae up to May 2007. In this revision, special emphasis is given to the role that these natural products play in their ecosystem; (ii) this thesis also provides data from feeding repellent experiments using lipophilic extracts from benthic invertebrates from two poorly known areas (eastern Weddell Sea and Bouvet Island). These experiments, carried out using sympatric predators, showed that more than half of the invertebrates tested possess chemical defenses against possible predators. In some of the cases, these defenses seem to be located in the most exposed/vulnerable parts of the organisms; (iii) one of the papers included in this thesis confirms that marine benthic invertebrates from Antarctic and sub-Antarctic waters have an interesting antitumoral potential. This work is the largest carried out in the area with very promising results for phyla such as Chordata, Porifera, and Cnidaria, among others; (iv) finally, this thesis comprises the description of 4 new species of annelid polychaetes from the Antarctic waters. These organisms belong to the families Cirratulidae (1 species from the genus Cirratulus), Dorvilleidae (2 species from the genus Ophryotrocha) and Siboglinidae (1 species from the genus Osedax), which were described from whale bones experimentally deployed in Deception Island (South Shetland Islands). These findings confirm the importance that whale bones may have in the Antarctic shallow-waters context
An ecocritical study of J.G. Ballard’s climate fiction novels
No full textBu çalışma, J.G. Ballard’ın 1960’ların başında yayımlamış olduğu iklim kurgu romanlarını çevreci eleştiri ekolü ışığında ele alan kapsamlı bir analizi içermektedir. J.G. Ballard’ın seçilmiş üç romanı — The Wind from Nowhere, The Drowned World ve The Drought çevreci eleştiri kuramından, özel olarak da sosyal ekoloji alt kuramından faydalanılarak incelenmiştir. Ballard’ın son dönem popüler eserlerinin gerçeküstücülük ve psikanaliz kuramlarındaki akademik araştırmaların çokluğuna rağmen bu çalışma, yazarın kıyamet sonrası iklim kurgu romanlarını çevreci eleştiri kuramı penceresinden ayrıntılı biçimde ele almayı hedeflemektedir. Ünlü İngiliz yazarın bu üç romanı, iklim kurgu alt türünün temel örnekleri arasında gösterilmektedir. Bu yüzden, çalışma Ballard’ın iklim kurgu roman üçlemesini çevreci eleştiri ekolü kapsamında, özellikle ikinci dalga çevreci eleştiri alt kuramı çerçevesinde incelemeyi önermektedir. Bu kapsamda araştırma Ballard’ın söz konusu eserlerini sosyal ekoloji perspektifinden eleştirmeyi amaçlamaktadır. Böylece çalışma, Ballard’ın ve pek çok eleştirmenin deneysel kurgu olarak adlandırdığı The Wind from Nowhere adlı romanında Batı insan merkezciliğinin nasıl alaşağı edildiğini açığa çıkarmaya odaklanmaktadır. Ayrıca, çalışma, Ballard’ın ikinci iklim kurgu romanı olan The Drowned World eserini sosyal ekofeminizm kuramı gözünden analiz etmektedir. Son olarak da Ballard’ın kuraklık temeline dayanan kıyamet senaryosu olan The Drought isimli romanının sosyal ekolojik bakış açısıyla irdelenmesi uygun görülmektedir. Pek çok araştırmacı ve kuramcıya göndermeler yapan bu çalışma temel olarak Murray Bookchin ve Karen J. Warren’ın kuramlarına dayanmaktadır. Çevreci eleştiri bağlamında farklı unsur ve meselelere değinen bu araştırma, J.G. Ballard’ın iklim kurgu roman üçlemesinin sosyal ekolojik motifler doğrultusunda ayrıntılı bir şekilde analiz edilmesi yönünde ısrarcı bir tutumu benimsemektedir.This study focuses on an ecocritical analysis of J.G. Ballard’s climate fiction novels of the early 1960s. Ecocritical perspectives, social ecological in specific have been utilized to shed light on the selected three novels of J.G. Ballard—The Wind from Nowhere, The Drowned World and The Drought. In contrast with the widespread scholarly research of surreal and psychoanalytic criticism in Ballard’s latter fiction, this study contemplates to analyse the author’s very first post-apocalyptic, climate fiction novels through the window of ecocritical theory. These three novels of the renowned British author are commonly considered as primary examples of the sub-genre of climate fiction. This study therefore proposes to analyse Ballard’s post-apocalyptic works of climate fiction by applying theories related to the school of ecocriticism, second wave of ecocriticism in particular. The study thereby aims to criticise Ballard’s oeuvre from the specific position of social ecology. Thus, the research reveals how Ballard dismantles and takes on western anthropocentrism in The Wind from Nowhere, the author’s first work of fiction, often dismissed by many including himself as an experimental work of fiction. Furthermore, the study also intends to criticise The Drowned World from a social ecofeminist viewpoint. Finally, it aspires to expose the social ecological motives behind The Drought, Ballard’s post-apocalyptic vision of a world running out of water. The study refers to a wide variety of scholars and theoreticians but mainly relies on the theories of Murray Bookchin and Karen J. Warren. Focusing on many different issues within ecocritical thought, the study insists on the scrutiny of social ecological motives in Ballard’s trilogy of climate fiction
