PERFORMATIVE CHARACTERISTICS OF GENDER: Subversion of Identity in Želimir Žilnik’s movie Marble Ass

U ovom tekstu se koncept performativnosti roda iznet u radovima savremene američke feminističke autorke Džudit Batler koristi kao metodološko sredstvo u analizi filma Želimira Žilnika “Marble Ass”. Igrani film se ovde posmatra kao tekst koji uspešno oslikava vrednosne i kulturne stavove društva u okviru koga je nastao. Cilj rada je pokušaj primene jedne savremene teorije o formiranju subjekta na konkretne primere koji se javljaju u navedenom filmu i provera mogućnosti koje koncept performativnosti roda nudi.This paper uses the concept of gender performativity, articulated by a contemporary American feminist author Judith Butler, as a methodological tool for the analysis of Želimir Žilnik’s movie Marble Ass. A motion picture is seen here as a text which successfully delineates values and cultural attitudes of the society in which it was created. The goal of the paper is to try to apply a contemporary theory of subject formation to the concrete examples shown in that movie, and to examine the possibilities offered by the concept of gender performativity

Stiffness dependence of critical exponents of semiflexible polymer chains situated on two-dimensional compact fractals

We present an exact and Monte Carlo renormalization group (MCRG) study of semiflexible polymer chains on an infinite family of the plane-filling (PF) fractals. The fractals are compact, that is, their fractal dimension $d_f$ is equal to 2 for all members of the fractal family enumerated by the odd integer $b$ ($3\le b< \infty$). For various values of stiffness parameter $s$ of the chain, on the PF fractals (for $3\le b\le 9$) we calculate exactly the critical exponents $\nu$ (associated with the mean squared end-to-end distances of polymer chain) and $\gamma$ (associated with the total number of different polymer chains). In addition, we calculate $\nu$ and $\gamma$ through the MCRG approach for $b$ up to 201. Our results show that, for each particular $b$, critical exponents are stiffness dependent functions, in such a way that the stiffer polymer chains (with smaller values of $s$) display enlarged values of $\nu$, and diminished values of $\gamma$. On the other hand, for any specific $s$, the critical exponent $\nu$ monotonically decreases, whereas the critical exponent $\gamma$ monotonically increases, with the scaling parameter $b$. We reflect on a possible relevance of the criticality of semiflexible polymer chains on the PF family of fractals to the same problem on the regular Euclidean lattices.Comment: 22 pages, 6 figure

On the number of contacts of a floating polymer chain cross-linked with a surface adsorbed chain on fractal structures

We study the interaction problem of a linear polymer chain, floating in fractal containers that belong to the three-dimensional Sierpinski gasket (3D SG) family of fractals, with a surface-adsorbed linear polymer chain. Each member of the 3D SG fractal family has a fractal impenetrable 2D adsorbing surface, which appears to be 2D SG fractal. The two-polymer system is modelled by two mutually crossing self-avoiding walks. By applying the Monte Carlo Renormalization Group (MCRG) method, we calculate the critical exponents $\phi$, associated with the number of contacts of the 3D SG floating polymer chain, and the 2D SG adsorbed polymer chain, for a sequence of SG fractals with $2\le b\le 40$. Besides, we propose the codimension additivity (CA) argument formula for $\phi$, and compare its predictions with our reliable set of the MCRG data. We find that $\phi$ monotonically decreases with increasing $b$, that is, with increase of the container fractal dimension. Finally, we discuss the relations between different contact exponents, and analyze their possible behaviour in the fractal-to-Euclidean crossover region $b\to\infty$.Comment: 15 pages, 3 figure

Oxidation-reduction potential of cerebrospinal fluid as a potential biomarker for ALS progression

Background: ALS is an oxidative stress-related fastpaced motor neuron disease for which there are no accurate biomarkers of progression. This largely hampers the development of therapeutics. Our aim was to test the applicability of oxidation-reduction potential (ORP) of cerebrospinal fluid (CSF) in ALS progression follow-up. Methods: ORP was measured using RedoxSYS (Aytu BioScience, Inc.) in CSF of 49 ALS patients (mean age 63 1.29 years; range 43-80 years; mean ALSFRSr score 37.47 0.90, range 21-48; m/f = 35/14) and 15 controls (mean age 48.93 3.68 years, range 21-67 years; m/f = 10/5). Results: Pearson correlation coefficient (R) between ALSFRSr score and ORP was 0.27 (p = 0.06). R was higher ( 0.45) when two outlier values were excluded from the calculus. Importantly, ALS patients had significantly higher mean ORP (ALS: 121.83 2.76mV; controls: 111.14 2.94 mV; p = 0.033). The difference was also significant for ORP normalized to age. Of note, ORP is reciprocally proportional to the pro-oxidative settings in biological samples. Discussion: Increased ORP values in ALS patients further confirm the role of oxidative stress in this neurodegenerative disease. ORP might find application as a biomarker for ALS progression/prognosis but further measurements on a larger cohort is warranted

Friction coefficient during the reciprocating sliding of uhmwpe in different environments

Dynamic friction coefficient (COF) of the reciprocating sliding contact of UHMWPE, was investigated in four different environments (dry contact; distilled water; pure Ringer's solution and with PMMA particles), at five values of low normal load (0.1 – 1 N) and three values of sliding speed (4 – 12 mm/s). Significant differences of COF values occurred at low load (0.1 N), whereas sliding speed did not influence COF values. Addition of PMMA particles in Ringer's solution produced significant increase of COF values, especially at the lowest load of 0.1 N

Hrvatske smjernice za dijagnostiku i liječenje benignoga paroksizmalnog pozicijskog vertiga (BPPV-a) [Croatian guidelines for diagnosis and management of benign paroxysmal positional vertigo (BPPV)]

BPPV is generally the most common cause of vertigo, caused by a pinch-off of tiny calcium carbonate crystals (called the otoconia or the otoliths) from the macula utriculi, most frequently due to the degenerative processes or a trauma, whereby the crystals, under the action of gravity in certain head positions coinciding with its direction, arrive to some of the semicircular canals, usually the posterior one, due to the existent anatomical circumstances and relationships, thus creating an inadequate stimulus of the cupular senses while floating through the endolymph and provoking symptoms of a strong and short-term dizziness. Two main clinical forms can be distinguished: canalolythiasis, with an accommodation of otolithic debris in the semicircular canal, and cupulolythiasis, with their location immediately next to the cupular sense. The diagnosis is established by a positive positioning test, Dix-Hallpike for the posterior and the supine roll for the lateral canal. Although one can expect a spontaneous recovery subsequent to few weeks or months, various methods of otolith repositioning to a less sensitive place lead to a prompt improvement while reducing or withdrawing the symptoms completely. These guidelines are intended for all who treat the BPPV in their work, with an intention to assist in the diagnosis and application of an appropriate therapeutic method
