Introduction: Concha bullosa is the most common variation of the middle turbinate of the paranasal sinuses. When it causes nasal obstruction, osteomeatal unit dysfunction, or rarely chronic infection, surgery is required. Case Report: We present a fungal infection of concha bullosa, which is a rare indication for surgery of the concha bullosa. A 59-year-old female patient presented with hemif...
interactions of rhizobia cultural filtrates with pseudomonas fluorescens on bean damping-off control
biotic as well as abiotic factors may influence the biocontrol activity and population density of pseudomonas fluorescens. however, limited studies have been carried out on the effects of extracellular metabolites of other competitor bacteria, especially on the biocontrol efficiency of p. fluorescens. a greenhouse experiment was conducted to evaluate the potential of the two p. fluorescens isol...
This paper presents the Fourier and wavelet characterization of vibratio...
Considering the strategic importance of coastal areas from various aspects, their protection against waves is a coast management necessity. Since long ago, strong coastal structures have protected coasts, but since they disturb the coastal ecosystem balance, effort has been made to use them less or make them more compatible with the coast. This research is specifically aimed to estimate the eff...
In this note, we show how to marginalize over the damping parameter of the PageRank equation so as to obtain a parameter-free version known as TotalRank. Our discussion is meant as a reference and intended to provide a guided tour towards an interesting result that has applications in information retrieval and classification.
In this article we consider an n-dimentional thermoelastic system with a viscoelastic damping localized on a part of the boundary. We establish an explicit and general decay rate result that allows a larger class of relaxation functions and generalizes previous results existing in the literature.
in this paper, a novel compensator based on magnetically controlled reactor with fixed capacitor banks (fc-mcr) is introduced and then power system stability in presence of this compensator is studied using an intelligent control method. the problem of robust fc-mcr-based damping controller design is formulated as a multi-objective optimization problem. the multi-objective problem is concocted ...
In this paper, the Unified Power Flow Controller (UPFC) is enhanced with a Chaotic Particle Swarm Optimization (CPSO) Damping Controller in order to mitigate the Low Frequency Oscillations (LFO) in a Single Machine Infinite Bus (SMIB) power system. The designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...
We study the neutrino oscillation problem in the framework of the wave packet formalism. The neutrino state is described by a packet located initially in a region S (source) and detected in another region D at a distance R from S. We examine how the oscillation probability as a function of variable R can be derived from he oscillation probability as a function of time t, the latter being found ...
A Cherenkov imaging camera was developed and installed in the second telescope of the CANGAROO-III project for observing gamma-rays having energies above 10eV. The camera consists of 427 pixels, arranged in a hexagonal shape at 0.17◦ intervals, each of which is a 3/4-inch diameter photomultiplier with a Winston-cone–shaped light guide. The camera discussed in this paper offers a wider field of ...
