It was determined that the thicknesses used for the ash powders are opaque for infrared radiation for thicknesses in the order of a millimeter.
Test results indicated that TFOT has a severer effect than UV radiation when bitumen thickness is 3 mm and bitumen thickness has a great influence on the ageing degree.
The direct-gap semiconductor can absorb solar radiation with a thickness, which is about 102 times less than the thickness of the mono- or polysilicon wafer.
The investigated parameters were radiation intensity, slice thickness and processing time.
When the potential was stepped to −0.3 V, the film grown absorbed the ellipsometer radiation once a thickness of 86 nm was reached.
This results can be used during the designing of high-temperature X-ray and gamma-radiation detectors for radiation hot rolling thickness gauges which are widely used in the metallurgy.
Since the direct-gap semiconductor can absorb solar radiation at its thickness much smaller than that of the Si wafer (or ribbon), the requirements for chemical purity and crystalline perfection of the absorber layer become much weaker.
Yet geological information seems possible to interpret from the gamma log, because at least the uppermost 100 m of the sandstone might be subdivided into four sequences each having on average, a downward decreasing gamma radiation and a thickness of, respectively, 30, 30, 20, and 20 m.
Following radiation therapy, the thickness of the subcutaneous fat increases whereas the muscle size tends to decrease 27.
It should consider the effects of variations in object/attenuator thickness and radiation beam quality.
