objective (s): scar formation in injured peripheral nerve bed causes several consequences which impede the process of nerve regeneration. several animal models are used for scar induction in preclinical studies which target prevention and/or suppression of perineural scar. this study evaluates the translational capacity of four of physical injury models to induce scar formation around the sciat...

conclusions our results indicated that an enormous proportion of k. pneumoniae isolated from sputum and surgical-wound swabs produced fully established biofilms. it is reasonable to assume the existence of a relationship between the site of infection and the formation of biofilm. a high level of genetic diversity among the k. pneumoniae strains was observed. results the distributions of the cli...

Crude bovine BMP was implanted into the thigh muscle pouch of mice. Tetracycline was injected 1 week and calcein was injected 2 weeks after implant. At 3 weeks after implant, the mice were sacrificed and reviewed histologically. Coexistence of calcified bone and osteoid was observed in Villanueva Goldner stained sections. Toluidine blue staining demonstrated cartilaginous matrix and adjacent lo...

Chondrules are significant indicators of processes occuring in the early solar nebula. However, the method of their formation is a continuing source of debate. There are a number of constraints on chondrule formation provided by careful chemical and isotopic analysis, as well as experiments undertaken in order to reproduce chondrules in the lab. Any proposed formation method must meet this wide...

Abstract—This paper presents the refinement method for two beams formation of wideband smart antenna. The refinement method for weighting coefficients is based on Fully Spatial Signal Processing by taking Inverse Discrete Fourier Transform (IDFT), and its simulation results are presented using MATLAB. The radiation pattern is created by multiplying the incoming signal with real weights and then...

PURPOSE To evaluate histological changes in the corneal stroma in pseudophakic bullous keratopathy. METHODS Twenty-eight patients (28 eyes) with pseudophakic bullous keratopathy underwent therapeutic penetrating keratoplasty at Shandong Eye Institute between January 2006 and November 2011. The patients were divided into two groups according to the duration of bullous keratopathy (<1.0 year gr...

The process of coalition formation, where distinct autonomous agents come together to act as a coherent group is an important form of interaction in multiagent systems. Previous work has focused on developing coalition formation algorithms which seek to maximize some coalition structure valuation function V (CS). However, for many real-world systems, evaluation of V (CS) must be done empiricall...

background : the aim of this study was to evaluate the performance of water ozonation on disinfection by-product formation. methods : experiments were carried out on samples taken from tajan river, mazandaran province, iran. samples of the pre-filtered raw water and from the 3.5-l water tank reservoir (wt) were analyzed for uv-254 absorbance, dissolved organic carbon (doc), hs and non-hs, chlor...

The probabilistic concept formation general problem in dealing with mixed-data scale environments is due to the use of different evaluation function for each attribute type. We claim that different behaviors for discrete and continuous evaluation functions are due to an unbalanced contribution for each attribute-type evaluation function inside the main evaluation function. This paper describes ...
