Objective: To evaluate the clinical and functional results of two surgical treatments of patellar dislocation in children. Material and Methods: A prospective study was undertaken from January 1995 to December 2009. Pre-postoperatively, the clinical and roentgenographic examinations were performed. Patellar dislocation was classified according to Bensahel’s criteria. There were two surgical techniques performed: 1) the iliotibial tract passing through patella (ITT), and 2) transferring vastus me...

In psychological terms personality is defined as the particular combination of emotional, attitudinal, and behavioral response patterns of an individual. It is believed philosophically that the personality of an individual is determined by following factors namely: 1) freedom vs determinism, 2) heredity vs environment, 3) uniqueness vs universality, 4) activeness vs reactiveness, 5) optimism vs pessimism. The paper work focuses on finding how teacher’s personality is reflected by being intuitive...

Bangladesh is one of the countries with a high rate of infant malnutrition and the major cause is inappropriate breastfeeding and complementary feeding practices. To improve the situation, both GO/NGO organizations are working intensively on the issue. In pursuance of this, AED and BRAC became partners in the Alive and Thrive project (A&T) for improving infant and young child feeding (IYCF) practices through motivation and counseling by BRAC’s volunteer commu

A convenient, environmentally friendly and mild green synthesis of imidazolidine-2-thiones, hydantoin and thiohydantoin derivatives was developed by the one-pot reaction of benzils, urea or thiourea derivatives, and strong base at with grinding. The key advantages are the short reaction times, excellent yields, simple workup, and easy purification in the solvent-free condition. The present method aimed to overcome the limitations and drawbacks of the reported methods such as hard work-up, low yi...

This paper presents an application of the gravimetric method using terrestrial and aerial data collected in one sector of the Parecis Basin, Brazil. The data received latitude and elevation corrections and also the Eotvos correction in the aerial survey case. Maps of Free-Air anomaly and Bouguer anomaly were obtained. These maps allowed us to identify the Pimenta Bueno Graben, which is an attractive region for oil and gas prospecting. Finally, the maps were compared and correlated to tectonic do...

Particle swarm optimization (PSO) is an evolutionary computation technique; it has shown its effectiveness as an efficient, fast and simple method of optimization. In this paper, the mathematical model represents NP-hard in the strong sense; since any instance of the quadratic assignment problem (QAP), I will implement the particle swarm optimization (PSO) for the quadratic assignment problem (QAP). The results show that the PSO is an appropriate optimization tool for use in determining the trai...

The impossibility of cloning an unknown quantum state is one of the basic rules governing quantum physics. This statement, known as the “no-cloning theorem”, prohibits perfect cloning, but doesn’t oppose approximate copying. In this paper, we will prove that, due to the uncontrollable quantum fluctuations, no perfect cloning can be achieved. Such a situation allows us to treat the no-cloning theorem as an equivalent one to Leibniz’s principle, and further unify them under the notion of uniquenes...

This work studies the effect of earthward electron beam on kinetic Alfven wave in plasma sheet boundary layer (PSBL). The particle aspect approach is adopted to investigate the trajectories of charged particles in the electromagnetic field of kinetic Alfven wave. Expressions are found for the dispersion relation, growth/damping-rate and associated currents in the presence of electron beam in homogenous plasma. Kinetic effects of electrons and ions are included to study kinetic Alfven wave becaus...

The use of polyamide coatings for electrical applications is restricted mainly because of its inadequate flame retardant behaviour. In order to improve its flame retardant behaviour, polyamide is modified by incorporating phosphorus moiety in its backbone. The structure of the phosphorus and poly amide was confirmed by infrared spectroscopy (FT-IR), NMR, thermo gravimetric analysis (TGA), differential scanning calorimetry (DSC), UL-94 vertical burning tests and char residue tests. From the resul...

Down syndrome (DS) is a genetic disease which has a set of characteristics that result in delays of basic motor skills. Physiotherapy aims to reduce delays in gross and fine motor skills. It also aims to prevent joint instabilities and deformities of the bones. A feature that has drawn the attention of therapists includes virtual reality as a method of rehabilitation. The goal of this study is to analyze the degree of effectiveness of the usage of the game in the rehabilitation of patients with ...
