Aberrations of the Cervical Carotid Artery Which May Be Dangerous in Pharyngeal Surgery—A Computed Tomographic Study  [PDF]
Johannes Gossner, Ricarda Manka, Joerg Larsen
Advances in Computed Tomography (ACT) , 2013, DOI: 10.4236/act.2013.21006

Background: There are recognised variations in the anatomical course of the cervical portion of the internal carotid artery. An aberrant vessel with direct contact to the pharyngeal wall could easily be injured during pharyngeal surgery or may appear as a pharyngeal pseudo mass. Previous anatomical studies predominantly involved older patients. The prevalence of such variations which are at risk of injury during pharyngeal surgery has thus not been established in a general patient population. Material and Methods: The course of the internal carotid artery in relation to the oro and hypopharyngeal walls was retrospectively evaluated bilaterally by simple visual inspection and measurement of the smallest distance between the respective vessels and the adjacent mucosal surface of the pharyngeal wall in 138 consecutive contrast-enhanced computed tomography scans of the neck. Results: 11/138 (7.9%) of patients demonstrated relevant cervical carotid artery aberrations, comprising medial kinking of a vessel with asymmetry of the adjacent pharyngeal lumen and/or an intimate submucous course in the pharyngeal wall with no identifiable separating fat plane. This prevalence increased with age. Simple visual inspection correlated well with the measurement of the smallest distance between an artery and the pharyngeal wall, which was statistically significant (p < 0.0001). Conclusions: The prevalence of about 8% in a general patient population is higher than previously recorded in anatomical studies. Prevalence increases with age. Otorhinolaryngologists should be aware of such variation as a risk factor for haemorrhagic complications during pharyngeal surgery and as a differential diagnosis of pharyngeal mass lesions, especially in older patients. Modern contrast-enhanced CT allows identification and characterisation of any surgically relevant variant vascular anatomy in the pre-operative work-up.

Quiet Crash Sites: Antun Mara i ’s Cro Car Crash Chronicle, after War/hol and Usput spomenici/ Sideroad Monuments and Aernout Mik’s Refraction
Ricarda Vidal
Altre Modernità , 2010,
Abstract: With the beginning of modernity death has been pushed to the margins of society. Indeed, for many, the only time they are confronted with death outside their immediate circle of friends or family is the chance encounter with the traffic accident, which is by now the most frequent form of public death in Western society. But while we try to deny death by institutionalising it and banning it from the everyday, the crowds who flock to the sites of accidents and violent deaths manifest our undiminished need to know about death. This essay examines our paradoxical attitude to accident sites, their attraction and repulsion, by looking at three artworks: Antun Maracic's photographic cycles Cro Car Crash Chronicle, after War/hol (2001-2) and Usput spomenici/ Sideroad Monuments (1999-2002) and Aernout Mik's video installation Refraction (2005). Maracic's two photo cycles are compendium works: Cro Car Crash Chronicle consists of a series of black-and-white press photographs of car crashes, and Sideroad Monuments focuses on crosses and memorials which mark the deaths of traffic victims. Mik's Refraction consists of a tripartite installation of a looped silent video of a large-scale traffic accident. In all three works the crash and the crash site are stylised into an aesthetic experience and the gallery becomes a place for the contemplation and acceptance of the fact of death.

Astrophysical aspects of fermion number violation in the supersymmetrical standard model
R. Manka,I. Bednarek
Physics , 1993, DOI: 10.1007/BF01552636
Abstract: The model of the supersymmetrical ball in the supersymmetrical standard model with additional global U(1) fermion symmetry is presented. We show that the supersymmetry breaking scale ( R-parity ), the global U(1) fermion symmetry scale and the electroweak symmetry breaking scale are strictly connected to each other. The realistic ball with $M \sim 10^5 - 10^9 M_{\odot} $ and the radius $ R \sim 10^{12} - 10^{14} cm $ is obtained. Inside the ball all full symmetries are restored. The ball is stabilized by superpartners and right neutrinos which are massless inside.
Role of nonlinear vector meson interactions in hyperon stars
Ilona Bednarek,Ryszard Manka
Physics , 2009, DOI: 10.1088/0954-3899/36/9/095201
Abstract: The extended nonlinear model has been applied to construct neutron star matter equation of state. In the case of neutron star matter with non-zero strangeness the extension of the vector meson sector by the inclusion of nonlinear mixed terms results in the stiffening of the equation of state and accordingly in the higher value of the maximum neutron star mass.
The Friedman Universe with the stochastic cosmological constant

Abstract: The Friedman Universe with the remnant stochastic scalar field in the hybrid inflation model is examined. It is shown that the small effective cosmological constant appears which increases the cosmological expansion.
Baryogenesis and phase transition in the standard model
D. Karczewska,R. Manka
Physics , 1996,
Abstract: The sphaleron type solution in the electroweak theory, generalized to include the dilaton field, is examined. The solutions describe both the variarions of Higgs and Gauge fields inside the sphaleron and the shape of the dilaton cloud surrounding the sphaleron. Such a cloud is large and extends far outside. These phenomena may play an important role during the baryogenesis which probably took place in the Early Universe.
The soliton stars evolution
Ilona Bednarek,Ryszard Manka
Physics , 1996, DOI: 10.1142/S0218271898000188
Abstract: The evolution of a soliton star filled with fermions is studied in the framework of general relativity. Such a system can be described by the surface tension $\sigma$, the bag constant $B$, and the fermion number density $\rho_{0}$. Usually one of these parameters prevails in the system and thus affects the spacetime inside the soliton. Whether it is described by Friedman or de Sitter metric depends on the prevailing parameter. The whole spacetime is devided by the surface of the soliton into the false vacuum region inside the soliton and the true vacuum region outside, the latter being described by the Schwarzschild line element. The aim of this paper is to study the equations of motion of the domain wall in two cases. In the first case the de Sitter metric describes the interior in the first case, and in the second case it is replaced by the Friedman metric. In both of them the Schwarzschild metric is outside the soliton. From the analysis of obtained equations one can draw conclusions concerning further evolution of a soliton star.
