Cogging torque is the major limitation of axial flux permanent magnet motors. The reduction of cogging torque during the design process is highly desirable to enhance the overall performance of axial flux permanent magnet motors. This paper presents a double-layer magnet design technique for cogging torque reduction of axial flux permanent magnet motor. Initially, 250 W, 150 rpm axial flux brus...

excessive production and stockpile of scrap tires cause some environmental and sanitary risks throughout the world. to manage these materials, possible use of soil-tire mixtures has been recently propounded in civil engineering projects. a few studies previously have been conducted to evaluate behavior of clay-tire mixtures, while swelling properties, consolidation and settlement characteristic...

this experiment was conducted with broiler chickens to evaluate the effects of high and low swelling bentonite (natural and processed by cuso4) supplementation in diets on performance and carcass traits. a total of 300 day-old aryan broiler’s chicks were used in a completely randomized design with 5 dietary treatments. six pen replicates of 10 chicks were assigned to each of five dietary treatm...

The physical properties of fish liver and rat liver mitochondria were compared as a function of temperature and osmotic pressure. The data indicate that fish mitochondria are more flexible and swell at a more rapid rate over a 0 to 30 degrees C temperature range, whereas the rates of swelling at 30 to 40 degrees C are comparable. The swelling rates of both fish and rat mitochondria vary with te...

By means of computerized tomography (CT) diffuse cerebral swelling has been shown to exist in the early stages of severe acute head injury. But, to our knowledge, it has not been intensively studied in blunt head trauma. The purpose of this study is to elucidate the clinical features, pathogenesis and outcome of the patients with diffuse cerebral swelling occurring in the case of blunt head tra...

he association of inflammation with tumors was first noted nearly 2,000 years ago by Galen. Today, chronic inflammation caused by intestinal diseases such as colitis is known to be a major contributing factor to the onset of colon cancer. In a new report by Florian Greten, Michael Karin (University of California, San Diego, CA), and colleagues, NFB, an inflammation-inducing transcription factor...

The swelling of mitochondria isolated from leaves, roots, and callus tissues of Nicotiana tabacum, L, var. White Gold, was measured by following changes in optical density at 520 mjt in buffered 025 M sucrose or 0.125 M KCI. Ozone induced rapid swelling of the isolated mitochondria and increased the permeability of mitochondrial membranes. The extent of mitochondrial swelling and the amount of ...

A 56 year old female presented to her primary care physician with a painless finger mass. She first noticed the mass about 7 years ago and it had been growing slowly since that time. Her former primary care physician had removed the mass about 5 years prior. She recalled being told at that time that it was a “ganglion cyst.” The mass had since returned and grown back to its former size. It was ...

The phenomenon of steam–water direct contact condensation has significance in a wide range industrial applications. Superheated steam was injected upward into cylindrical water vessel. Visual observations were conducted on turbulent jet to determine the dimensionless length compared nozzle exit diameter and maximum swelling ratio as function mass flux at exit, with gas ranging from 295–883 kg/m...
