In this article, the biodegradation process and bone formation of a mineralized collagen reconstruction rod embedding in necrosis of human femoral head were investigated by imageological and histological methods. Computed radiography (CR) computerized tomography (CT), common pathological section and hard tissue section analysis were used to evaluated the dynamics of imageological and histopatho...

In this experiment, κ, the thermal conductivity of a rod of brass, was measured by periodically heating one end of the rod. Turning the heater attached to the rod on and off with a 10 mHz square wave signal, waves of heat were sent along the length of the rod, measured by two thermistors a distance ∆x apart. Taking these temperatures as a function of time, a Fourier transform was applied to a 1...

In this paper, KENOV.a module of SCALE code system was used to perform Monte Carlo simulation of the TRIGA MARK II research reactor benchmark experiments [1,2] in steady state operation conditions. Robert Jeraj and his coworkers have presented a similar simulation of the TRIGA MARK II research reactor benchmark experiments via MCNP4A in 1997. [3] The core excess reactivity measurement experimen...

Continuous casting is used to mass produce basic metals into long, semi-finished shapes with constant cross section, which are later processed into over 800 million tons of steel, 20 million tons of aluminum, and 1 million tons of copper, nickel, and other metal products in the world each year. Cross-sections can be rectangular, for later rolling into plate or sheet, square for long products, c...

The article is devoted to solving an inverse boundary value problem for a rod consisting of composite materials. In the problem, it required, using information about temperature heat flow in media section, determine at one ends rod. paper presents method projection regularization, which made possible approximately estimate error obtained solution problem. To check computational efficiency this ...

Rod modulation of an annular surround can produce brightness contrast in a test field centered at 100 from the fovea. In our research, stimuli originated from a colorimeter that provided 4 primaries in both the circular test and the annular surround fields, and allowed independent modulation of the rods and each of the short (S)-, middle (M)-, and long (L)-wavelength-sensitive cone types. The c...

Modern aircraft need increased maneuverability to maintain a competitive position. One way improve this characteristic is use methods adjust the thrust vectors of jet engine nozzle. method controlling nozzle interceptors devices various shapes that extend into channel and cause an uneven distribution pressure along walls channel. The extension rod interceptor near critical section creates great...
