Modeling iceberg longevity and distribution during Heinrich Events. Paleoceanography and Paleoclimatology, 37(6), (2022): e2021PA004347, https://doi.org/10.1029/2021pa004347.During the last glacial period (120–12 ka), the Laurentide ice sheet discharged large numbers of icebergs into the North Atlantic. These icebergs carried sediments that were dropped as the icebergs melted, leaving a record of past iceberg activity on the floor of the subpolar North Atlantic. Periods of significant iceberg discharge and increased ice-rafted debris (IRD) deposition, are known as Heinrich Events. These events coincide with global climate change, and the melt from the icebergs involved is frequently hypothesized to have contributed to these changes in climate by adding a significant volume of cold, fresh water to the North Atlantic. Using an iceberg model coupled with the Massachusetts Institute of Technology Global Circulation Model numerical circulation model, we explore the various factors controlling iceberg drift and rates of melt that influence the spatial patterns of IRD deposition during Heinrich Events. In addition to clarifying the influence of sea surface temperature and wind on the path of an armada of icebergs, we demonstrate that the same volume of ice can produce very different patterns of iceberg drift simply by altering the size of icebergs involved. We note also a significant difference in the seasonal locations of icebergs, influenced primarily by the changing winds, and show that the spatial patterns of IRD for Heinrich Event 1 most closely corresponds to where icebergs are located during the summer months. Consistent with proxy evidence, the ocean must be several degrees colder than temperatures estimated for the Last Glacial Maximum in order for icebergs to travel the distance implied by Heinrich Layers
Lightning activity in the regions of MSC over Czechia
Title: Lightning activity in the regions of MCS over Czechia Author: Michaela Arnoštová Department: Department of Atmospheric Physics Supervisor: Mgr. Michal Žák, Ph.D., Department of Atmospheric Physics Abstract: This bachelor's thesis deals with lighting activity and its detection in mesoscale convective systems (MCS) over the Czech Republic and adjacent areas. The first part describes the formation and development of MCS, electrical charge distribution inside clouds, types of lightning and their detection. The second part is devoted to five specific MCS that occurred in different time periods. Data of lightning detection network (LINET) are used to describe the characteristics of lightning, especially their temporal and spatial development, occurrence of different types of lightning and development of their current amplitude and altitude. Keywords: Mesoscale convective system, lightning activity, lightning detectio
Riflessioni linguistiche sul tedesco e sul russo in Julya Rabinowich: un confronto tra narrazione autobiografica orale e il romanzo Spaltkopf
Linguistic Reflections in German and Russian in Julya Rabinowich: A Comparative
Study of Oral Autobiographical Narrative and the Novel Spaltkopf.
The Austrian author Julya Rabinowich, born in Leningrad in 1970 to a family of Rus-
sian Jews and emigrated to Vienna at the age of 7, is one of the most renowned repre-
sentatives of contemporary literature in the German language. Rabinowich made her
literary debut in 2008 with Spaltkopf (Split Head), her most strongly autobiographical
novel. In 2012, the writer was interviewed by Michaela Bürger-Koftis as part of the
research project Polyphonie. Mehrsprachigkeit_Kreativität_Schreiben. This interview
can be understood as a linguistic biography, as Rabinowich recounts her experiences
related to the languages in her linguistic repertoire, focusing particularly on German
and Russian. From this account, the author’s Spracheinstellungen (linguistic attitudes),
as well as the impressions and emotions related to her two main languages, emerge.
The aim of this study is to compare the interview passages in which Rabinowich
expresses herself regarding German and Russian with excerpts from Spaltkopf where
the relationship of the protagonist, Mischka, with these two languages emerges. In this

way, it will be possible to determine whether Spaltkopf reflects not only the author’s
migratory experience but also her linguistic biography. Furthermore, it will be analyz-
ed if and to what extent the expression of linguistic attitudes and emotions related to
German and Russian differs between the novel and the oral autobiographical account.
To examine how Rabinowich expresses her linguistic experiences and emotions relat-
ed to German and Russian, a qualitative analysis of the texts will be conducted, with
a theoretical approach based on the concepts of linguistic biography and verbalization
of emotions developed by Brigitta Busch and Reinhard Fiehler
Questions and clarity: insights from applying computational methods to paleoclimate archives
Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Marine Geology & Geophysics at the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution May 2022.It is a scientifically accepted fact that the Earth’s climate is presently undergoing significant changes with the potential for immense negative impacts on human society. As evidence of these impacts become clear and common, it becomes ever more important to constrain the nature, magnitude, and speed of changes to Earth systems. A fundamentally important tool to this understanding is the Earth’s past, recorded in the geologic record. There, lie examples of climate change under various forcings: important data for understanding the fundamental dynamics of climate change on our planet. However, when a climate signal is
written in the geologic record, it is coded into the language of proxies and distorted by time. This thesis endeavors to decode that record using a variety of computational methods on a number of challenging proxies, to draw more information from the climate past than has previously been possible. First, machine learning and computer vision are used to decipher the primary, centimeter-scale textures of carbonate deposits in Searles Valley and Mono Lake, California. This work is able to connect facies in the tufa at Searles, grown during the Last Glacial Period, and those forming presently at Mono Lake. Next, the tracks of icebergs purged during Heinrich Events are simulated using the MIT General Circulation Model. This work, running multiple experiments exploring different aspects internal and external to the icebergs, reveals wind and sediment partitioning as centrally important to the spatial
extent of Heinrich Layers. Each of these works considers a traditional geologic archive – a carbonate facies, a marine sediment layer – and uses computational methods to approach that archive from a different perspective. By applying these new methods, more information can be gleaned from the geologic record, building a richer narrative of the Earth’s climate history. The final chapter of this thesis discusses effective teaching and strategies for building communities to support teaching practice in Earth Science departments.This thesis work was funded by the MIT EAPS Rasmussen and Whiteman Fellowships, NSF Project Number NSF-EAR-1903544, and the WHOI Academic Programs Office

Michaela Pavlatova
The purpose of this text is to reassess the animation like an aesthetics human practice even out of the cinematographic field. An important resource are the Semir Zeki`s investigations about neuroaesthetics. Im going to review the origin and historic course of animation from the prehistory, bearing in mind the human evolutive process of perception (body-brain) and the human development from childhood that makes possible the existence of the animation.
For that, as example, Im going to put into context the animated Films of the czech filmmaker Michaela Pavlátová. Her live related to animation and the characteristics of her Films will appear as motive(motivation) to expand ideas like how the environment can influence the way to represent the space, or the relations between politic and czech animation, or how works the perception of color in the brain, or the importance of the faces in social relationships, and how that motives appears and becomes art across author hands
Hervé Guibert: Resurrection of the Author
1 Michaela Rumpíková, Résurrection de l'auteur : Hervé Guibert Abstract Hervé Guibert's writings are shocking, revolting, surprising with their explicit and expressive content. The author's desire to show, to reveal and to expose himself transforms his private universe into a space where intimacy becomes extimacy. His exhibitionist project is accomplished with the assistance of a literary genre, autofiction, the new postmodern cosmos of the "I". This thesis seeks to analyse the notion and the modalities of his "I", intimately connected to the themes of body, illness, life, death and resurrection, in his literary chronicles of AIDS, To the Friend Who Did Not Save My Life, The Compassionnate Protocol, Modesty, or Immodesty and The Man in the Red Hat. The "I" of the autodiegetic narrator appears as fragmentary and unstable. His "self" configures and unconfigures at the same time. There is a sense of alienation from his own body which has been dramatically altered by the illness. As a consequence, we witness both physical and psychological defragmentation of the subject. The body, constituent of the "I" identity, gradually transforms into an impersonal "it", an entity apart. In order to (re)construct himself, the author uses various writing processes that help him become familiar with his new "self". Finally,..
