Kinetics of Deposition of Oriented Superdisks

We use numerical Monte Carlo simulation to study kinetics of deposition of oriented superdisks, bounded by the Lame curves of the form $|x|^{2p}+|y|^{2p}=1$, on regular planar substrate. It was recently shown that the maximum packing density, as well as jamming density $\rho_{J}$, exhibit discontinuous derivative at $p=0.5$, when the shape changes from convex to concave form. By careful examination of the late-stage approach to the jamming limit, we find that the leading term in temporal development is also nonanalytic at $p=0.5$, and offer heuristic excluded-area arguments for this behavior

Self-trapped bidirectional waveguides in a saturable photorefractive medium

We introduce a time-dependent model for the generation of joint solitary waveguides by counter-propagating light beams in a photorefractive crystal. Depending on initial conditions, beams form stable steady-state structures or display periodic and irregular temporal dynamics. The steady-state solutions are non-uniform in the direction of propagation and represent a general class of self-trapped waveguides, including counterpropagating spatial vector solitons as a particular case.Comment: 4 pages, 5 figure

Bioethanol production from milling industry by-product in a laboratory-scale bioreactor

Bioethanol produced by biomass fermentation is a renewable and environmentally friendly energy source and has significant potential as a replacement for liquid fossil fuels. Due to the world moving toward more sustainable energy sources, the production of bioethanol has been steadily increasing. This research aims to investigate the efficiency of bioethanol fermentation from a milling industry by-product in a laboratory-scale bioreactor. Prior to fermentation in a bioreactor, for preparation of a milling industry by-product, two different thermo-enzymatic procedures were investigated and compared, and based on the obtained results the more efficient procedure was selected and used for the experiment in a bioreactor. The bioethanol fermentation was carried out in a 14-litre bioreactor in batch mode under anaerobic conditions at 30°C. The obtained results showed that this by-product can be used for the production of bioethanol but that further optimization is necessary to improve the overall efficiency of the bioprocess

Extra Dimensions: A View from the Top

In models with compact extra dimensions, where the Standard Model fields are confined to a 3+1 dimensional hyperplane, the $t \bar t$ production cross-section at a hadron collider can receive significant contributions from multiple exchange of KK modes of the graviton. These are carefully computed in the well-known ADD and RS scenarios, taking the energy dependence of the sum over graviton propagators into account. Using data from Run-I of the Tevatron, 95% C.L. bounds on the parameter space of both models are derived. For Run-II of the Tevatron and LHC, discovery limits are estimated.Comment: Typos corrected, references added. 12 pages, LaTeX, 2 ps figure

Seasonality of trichinellosis in patients hospitalized in Belgrade, Serbia

A retrospective study of the course and outcome of trichinellosis in a series of 50 patients hospitalized at the Institute for Infectious and Tropical Diseases in Belgrade between 2001 and 2008 was performed. Clinical diagnosis of trichinellosis was based upon the patients' clinical history, symptoms and signs, and eosinophilia. The occurrence of cases showed a strong seasonality (P lt 0.00011. The incubation period ranged between one and 33 days. The mean time between onset of symptoms and admission was nine days. Family outbreaks were the most frequent. Smoked pork products were the dominant source of infection (76 %). Fever was the most frequent clinical manifestation (90 %), followed by myalgia (80 %) and periorbital edema (76 %). 43 patients were examined serologically and 72 % of them had anti-Trichinella antibodies. Eosinophilia and elevated levels of serum CK and LDH were detected in 94, 50 and 56 % of the patients, respectively. All patients responded favorably to treatment with mebendazole or albendazole, but eight developed transient complications. Trichinellosis remains a major public health issue in Serbia
