A brief review and a new treatment for rigid bodies collision models

In general the motion of a body takes place in a confined environment and collision of the body with the containing wall is possible. In order to predict the dynamics of a body in this condition one must know what happens in a collision. Therefore, the problem is: if one knows the pre-collision dynamics of the body and the properties of the body and the wall one wants to predict the post-collision dynamics. This problem is quite old and it appeared in the literature in 1668. Up to 1984 it seemed that Newton's model was enough to solve the problem. But it was found that this was not the case and a renewed interest in the problem appeared. The aim of this paper is to treat the problem of plan collisions of rigid bodies, to classify the different models found in the literature and to present a new model that is a generalization of most of these models.

Transforming Bodies, Wandering Desires. Intra-actions of Gender and Sexuality in Non-heterosexual Transgender Embodiment

Pro gradu -tutkielmani käsittelee sukupuolen ja seksuaalisuuden keskinäisiä intraaktiivisia vuorovaikutussuhteita elettyjen, ei-heteroseksuaalisten transsukupuolisten ruumiiden kokemuksissa. Tutkielmani haastaa sukupuolen ja seksuaalisuuden pysyvyyden käsityksiä sekä niihin liittyviä yhteiskunnallisia normeja kuvaten tapoja, joilla seksuaalisuuden ja sukupuolen kokeminen ja käytännöt liikkuvat, kehittyvät ja vuorovaikuttavat eletyissä transsukupuolisuuden ruumiillistumissa. Haastattelen kuutta suomalaista, syntymässä naiseksi määriteltyä transsukupuolista henkilöä liittyen heidän kokemuksiinsa sukupuolesta, seksuaalisuudesta ja näiden muutoksista heidän tähänastisen elämänsä aikana. Tarkastelen nauhoitettuja ja litteroituja haastattelutekstejä transtutkimusta, queer-teoriaa ja feminististä uusmaterialistista filosofiaa yhdistävän teoreettisen kehyksen kautta keskittyen siihen, miten sukupuoli ja seksuaalisuus vaikuttavat toistensa kehitykseen, muutokseen ja materialisoitumiseen eri elämänvaiheissa ja tilanteissa. Erityisen tärkeiksi teoreettisiksi vaikuttajiksi tutkielmassani muodostuvat Judith Butlerin Gender Trouble (2006 [1990]) -teoksessaan hahmottelema performatiivisen sukupuolen teoria, Sara Ahmedin analyysi teoksessa Queer Phenomenology. Orientations, Objects, Others (2006) ja Karen Baradin teoksessa Meeting the Universe Halfway. Quantum Physics and the Entanglement of Matter and Meaning (2007) teoretisoima toimijuudellinen realismi. Päästäkseni kiinni sukupuolen ja seksuaalisuuden yhtymäkohtiin erittelen ensin niitä ominaisuuksia ja kokemuksia, jotka näyttäytyvät haastatteluteksteissäni oleellisina seksuaalisuuden ja sukupuolen kannalta. Tarkastelen seksuaalisuutta suuntautumisen, halun ja seksuaalisten käytäntöjen näkökulmasta: vaikka nämä seksuaalisuuden aspektit ovat kiinteästi kytköksissä toisiinsa, niitä ei voi kokonaan palauttaa toisiinsa. Sukupuolta käsittelen performatiivisuuden näkökulmasta painottaen transsukupuolisiin ruumiisiin ja niiden materiaalisuuteen liittyviä erityispiirteitä. Sukupuolen ja seksuaalisuuden suhteita toisiinsa tarkastelen sekä sellaisissa tilanteissa, joissa niitä on vaikea erottaa toisistaan, että sellaisissa, joissa niiden voidaan nähdä tuottavan toinentoisiaan. Tutkielmallani on etnografisia, filosofisia ja poliittisia ulottuvuuksia. Yhtäältä tahdon kuvata ja analysoida elettyjä transsukupuolisia kokemuksia ja tuottaa tietoa vähän tutkitun ihmisryhmän todellisuudesta. Toisaalta osallistun sukupuolifilosofiseen keskusteluun ruumiillisuudesta ja sukupuolen ja seksuaalisuuden olemuksesta. Lähestyn tutkimusprosessiani niin sanotusta transgender standpoint -näkökulmasta; kirjoitan transsukupuolisena ruumiina, transsukupuolisia ruumiita koskien, pyrkimyksenäni edistää elävien transsukupuolisten ruumiiden asemaa, toimijuutta ja näkyvyyttä yhteiskunnassa.

Morphological changes of carotid bodies in acute respiratory distress syndrome: a morphometric study in humans

Carotid bodies are chemoreceptors sensitive to a fall of partial oxygen pressure in blood (hypoxia). The morphological alterations of these organs in patients with chronic obstructive pulmonary disease (COPD) and in people living at high altitude are well known. However, it is not known whether the histological profile of human carotid bodies is changed in acute clinical conditions such as acute respiratory distress syndrome (ARDS). The objective of the present study was to perform a quantitative analysis of the histology of carotid bodies collected from patients who died of ARDS. A morphometric study of carotid bodies collected during routine autopsies was carried out on three groups: patients that died of non-respiratory diseases (controls, N = 8), patients that presented COPD and died of its complications or associated diseases (N = 7), and patients that died of ARDS (N = 7). Morphometric measurements of the volume fraction of clusters of chief cells were performed in five fields on each slide at 40X magnification. The numerical proportion of the four main histological cell types (light, dark, progenitor and sustentacular cells) was determined analyzing 10 fields on each slide at 400X magnification. The proportion of dark cells was 0.22 in ARDS patients, 0.12 in controls (P<0.001), and 0.08 in the COPD group. The proportion of light cells was 0.33 (ARDS), 0.44 (controls) (P<0.001), and 0.36 (COPD). These findings suggest that chronic and acute hypoxia have different effects on the histology of glomic tissue.

Porous Bodies, Porous Minds. Emotions and the Supernatural in the Íslendingasögur (ca. 1200–1400)

In my PhD Thesis, I study the conceptions and representation of emotions in medieval 13th and 14th-century Iceland. I have used Icelandic saga literature as my source material and Icelandic Family sagas (Íslendingasögur) as my main sources. Firstly, I wished to explore in my study the medieval Icelandic folk theory of emotions: what emotions were thought to be, from what they originated and how they operated? Secondly, in earlier research it has been shown that emotions were seldom described in Íslendingasögur. They were mostly represented in dialogue, poetry or in somatic changes (e.g. turning pale). Consequently, I examined whether medieval Icelanders had alternative emotion discourses in literature, in addition to the usual manner of representation. My study consists of qualitative case studies, and I have analysed the sources intertextually. I suggest that medieval Icelanders regarded emotions as movements of the mind. The mind existed in the heart. As a consequence, emotions were considered physical in nature. The human body and therefore also the human mind was considered porous: if the mind of the person was not strong enough, supernatural agents and forces could penetrate theboundaries of his/her body as winds or sharp projectiles. Correspondingly, minds of strong-willed people could penetrate the minds of others. As a result, illness and emotions could upspring. People did not always distinguish between emotions and physical illnesses. Excessive emotions could cause illness, even death. Especially fear, grief and emotions of moral responsibility (e.g. guilt) made people vulnerable to the supernatural influence. Guilt was considered part of the emotional experience of misfortune (ógæfa), and in literature guilt could also be represented as eye pain that was inflicted upon the sufferer by a supernatural agent in a dream. Consequently, supernatural forces and beings were part of the upspring of emotions, but also part of the representation of emotions in literature: They caused the emotion but their presence also represented the emotional turmoil in the lives of the people that the supernatural agents harassed; emotions that had followed from norm transgressions, betrayal and other forms of social disequilibrium. Medieval readers and listeners of the Íslendingasögur were used to interpreting such different layers of meaning in texts.

Slöjd som process och produkt : Talking Tools som dokumentations- och utvärderingsverktyg

Syftet med denna studie är att granska hur användningen av smarttelefoner kan stöda elevens reflektion av sin egen slöjdprocess och samtidigt se hur eleven dokumenterar sin slöjdprocess med hjälp av Talking Tools (TT). Fokus i denna studie ligger på dokumentation av elevens slöjdprocess, men jag behandlar även presentation av slöjdprodukter och olika möjligheter till och sätt på hur eleverna använder TT på en smarttelefon i slöjdundervisningen. En förändring i hur informations- och kommunikationsteknik (IKT) används sker och kommer även att ske i fortsättningen i grundskolan. Då en ny läroplan för den grundläggande utbildningen tas i bruk år 2016 kommer IKT att ha en avsevärt större roll. Denna förändring lägger press på lärare och på skolan överlag för att skapa ändamålsenliga metoder i användningen av IKT. Studien baserar sig på intervjuer med elever som använt TT under ett arbetsområde i slöjden. Elva elever presenterade först sina slöjdprodukter för forskaren varefter eleverna intervjuades. Eleverna hade tillgång till sina slöjdbloggar gjorda i TT under intervjutillfällena. Intervjuerna filmades och lades ihop med bloggarna för att förenkla analysen av materialet. I den här undersökningen framkom att dokumentationen av slöjdprocessen bidrog till en reflektion av när bilder och texter från bloggarna användes under presentationerna. Då kraven på dokumenteringen av arbetet i skolan blir högre i och med läroplanen 2016 tror jag att Talking Tools kan vara ett hjälpmedel för elever och lärare i förverkligandet av bland annat användningen av IKT i arbetet i skolan. Detta förutsätter att eleverna ges tid för användningen samt att tekniken fungerar.

Chemical composition and radical scavenging activity of melanin from Auricularia auricula fruiting bodies

Melanin extracted from Auricularia auricula fruiting bodies (AAFB) was examined by element analyzer, amino acid analyzer, inductively coupled plasma-optical emission spectrometry. Elemental composition analysis revealed that main component of AAFB melanin was pheomelanin. Amino acid analysis showed that 16 amino acids were found in AAFB melanin and total amino acid content was 321. 63 mg/g. There were 13 detectable metal elements in AAFB melanin, which was rich in Ca, Fe, Cu and Zn. In addition, AAFB melanin exhibited stronger scavenging activities on 2,2-diphenyl-l-picrylhydrazyl (DPPH) radical, superoxide radical and hydroxyl radical with IC50 values of 0.18, 0.59 and 0.34 mg/mL, respectively. These results indicated that AAFB melanin might be potentially used as a natural antioxidant.

Extraction optimization of antioxidant polysaccharides from Auricularia auricula fruiting bodies

AbstractThe extraction conditions (liquid-solid ratio, temperature and time) of antioxidant polysaccharides from Auricularia auricula fruiting bodies (AAFB) were optimized using response surface methodology (RSM). The Box-Behnken experimental results showed the optimum extraction conditions as follows: a liquid-solid ratio of 38.77 mL/g, a temperature of 93.98 °C and a time of 3.41 h. Under these conditions, the maximal polysaccharide yield was 10.46 g/100 g. In addition, AAFB polysaccharides exhibited stronger antioxidant activities by evaluating of Fe2+-chelating ability and hydroxyl radical scavenging activity with IC50 values of 0.43 and 0.38 mg/mL, respectively. These results indicated that AAFB polysaccharides might be potentially used as a natural antioxidant.

(Re)Thinking bodies : Deleuze and Guattari's becoming- woman

Abstract (Re)thinking Bodies: Deleuze and Guattari 's becoming-woman seeks to explore the notion of becoming-woman, as put forth by Gilles Deleuze and Felix Guattari in their collaborative 1982 text, A Thousand Plateaus: Capitalism and Schizophrenia, and as received by such prominent feminist theorists as Rosi Braidotti and Elizabeth Grosz. Arguing that the fairly decisive repudiation of this concept by some feminist theorists has been based on a critical misunderstanding, this project endeavors to clarify becomingwoman by exploring various conceptions of the body put forth by Baruch de Spinoza, Friedrich Nietzsche and Simone de Beauvoir. These conceptions of the body are indispensible to an appreciation of Deleuze and Guattari's notion of a body lived on both an immanent and transcendent plane, which, in turn, is indispensable to an appreciation of the concept of becoming (and, in particular, the concept of becoming-woman) as intended by Deleuze and Guattari.

Canadianness is Wilderness? Violent Love Relationships with ‘Wild’ Bodies

This thesis reveals contradictions that Canadians experience with groups attached to western construction of wilderness namely Indigenous people and wildlife. My study analyzes how the discourse of Canadian wilderness identity is played out in Algonquin Provincial Park and Bruce Peninsula National Park in comparison to non-nature/urban spaces (Greater Toronto Area). My investigation employs a critical discourse analysis and participant observation. I undertake three main tasks: 1) I describe how violent love is a dominant discourse at the Parks, 2) I examine evidence of animals and Indigenous people being produced relationally in the Parks, and 3) I analyze how relationships are spatially organized. My research reveals that the Parks conceal practices of violence that are central to the intersections of speciesism and colonialism. I demonstrate how violent love operates across a continuum that is influenced by spatial belonging and distance. This research is a contribution to the production of non-speciesist knowledge.

Bodies, Saracen giants, and the medieval romance : transgression, difference, and assimilation

Bodies, Saracen Giants, and the Medieval Romance: Transgression, Difference, and Assimilation explore le traitement des corps de trois géants Sarasins dans les romances de Roland and Vernagu (c. 1330), Sir Beues of Hamtoun (c. 1330), et The Taill of Rauf Coilyear (c. 1513-42).Grâce à une étude de la représentation de ces trois géants Sarasin, la signification du corps humain au Moyen Age, et des pratiques de la Chrétienté an accord avec les discours et idéologies envers le Proche-Orient qui existaient dans l’Occident médiéval, ce mémoire de maîtrise juxtapose le géant Sarasin et le héros de la romance pour indiquer une similarité apparente entre leur deux corps et leur religion respective. La romance démontre avec hésitation un désir d’assimiler le géants Sarasin dans le code héroïque ainsi que dans la religion chrétienne, mais souvent rejette avec suspicion le corps du géant par sa mort sur le champ de bataille. Malgré sa mort ou son assimilation dans le code héroïque et la Chrétienté, le corps du géant Sarasin demeure toujours important dans le contexte de la Romance, puisqu’il contribue à la construction de l’identité du héros, de sa foi, et de sa société.

Building Beyond Limits : Fantastic Collisions Between Bodies and Machines in French and English Fin-de-Siècle Literature

«Construire hors limite: collisions fantastiques entre corps et machines dans la littérature fin-de-siècle française et anglaise» explore un ensemble de textes qui ont surgi à la fin du dix-neuvième siècle en réponse et en réaction à la fulgurante évolution de l’environnement scientifique et technologique, et qui considèrent la relation entre l’homme et la machine en fantasmant sur la zone grise où ils s’intersectent. Les principaux textes étudiés comprennent L’Ève future de Villiers de l’Isle-Adam, Le Surmâle d’Alfred Jarry, Trilby de George Du Maurier, Le Château des Carpathes de Jules Verne, ainsi qu’une sélection de contes dont nous pouvons qualifier de «contes à appareils», notamment «La Machine à parler» de Marcel Schwob. Utilisant la théorie des systèmes comme base méthodologique, cette dissertation cherche à réinterpréter les textes de la fin du dix-neuvième siècle qui naviguent les limites de l’humain et du mécanique et les surfaces sensibles où ils se touchent et interagissent en les réinscrivant dans un projet plus vaste de construction d’identité qui défie le temps chronologique et les échelles mathématiques. Le lien entre la théorie des systèmes et l’architecture – comme méthode d’organisation d’espace blanc en espace habitable – est exploré dans le but de comprendre la manière dont nous façonnons et interprétons le néant à l’origine de l’identité individuelle, et par association collective, en pratiquant littéralement la schématisation et la construction du corps. Des auteurs tels Villiers et Jarry imaginent la construction du corps comme une entreprise scientifique nécessairement fondée et réalisée avec les matériaux et les technologies disponibles, pour ensuite démanteler cette proposition en condamnant le corps technologique à la destruction. La construction d’une identité amplifiée par la technologie prend donc des proportions prométhéennes perpétuellement redessinées dans des actes cycliques de rasage (destruction) et d’érection (édification), et reflétées dans l’écriture palimpsestique du texte. L’intégrité du corps organique étant mis en question, le noyau même de ce que signifie l’être (dans son sens de verbe infinitif) humain pourrait bien s’avérer, si l’on considère la correspondance entre perte de voix et état pathologique dans les textes de Du Maurier, Verne et Schwob, être une structure des plus précaires, distinctement hors sens (unsound).
