Abstract

Permanent magnet synchronous motors (PMSM) are a type of motors that have permanent magnets mounted on the rotors instead of the rotor windings. This particular design gives the motor a few advantages over ordinary induction synchronous motors. The magnets attached to the rotor do not require excitation, which reduces the power consumption in PMSM. This gives the motor high operational efficiency and reduces the motor active diameter. PMSM are therefore associated with applications that require high torque but have limited operation space. The permanent magnets suffer from flux leakage and are therefore aligned in a pattern that minimizes flux ...

The Relationship of Beauty and Death in Yukio Mishima’s “The Temple of the Golden Pavilion”

Introduction The novel written by Yukio Mishima represents a true incident happened in Japan in 1950, when a boy set fire to one of the most beautiful and well-known Zen temples. This event caused shock among the public and raised serious and controversial questions regarding the cultural and social issues in the country. In the trial, the boy claimed: “I hate myself, my evil, ugly, and stammering self”. In the result, it was concluded that the boy has burnt down the temple due to self-hate and obsession with everything beautiful. He could not help to remain calm when he ...

Introduction

In the last few centuries, our understanding of universe has grown by leaps and bounds. Before seventeenth century, people generally believed that the Earth is at centre of the universe and all heavenly bodies move around the Earth. Galileo challenged the idea and published his papers in support of Copernican heliocentric theory that the Earth and other planets move around the Sun. Our understanding of universe grew further. We realized that the Sun is not unique and there are hundreds of billions of stars in the galaxy, which are brighter ...

Introduction to proteins

Proteins are polypeptides made up of amino acids joined together by polypeptide bonds. The number of amino acids in a protein molecule can vary from several amino acids to thousands of amino acids. Proteins are made of a combination of several of the 20 naturally occurring amino acids as well as other minor amino acids. Proteins are very important molecules in the body .They form the structural components of animal and human tissue (Yildiz, 2009).

The primary structure of proteins is determined by the sequence of the amino acids in the protein. A functional amino acid must contain the correct sequence ...
