Thickness influence on dielectric loss
Journal of Physics and Chemistry of Solids, 1976Abstract Dielectric loss is essentially a macroscopic property valid for sufficiently thick samples. However, if the sample has a defect structure which varies with thickness and takes part in a particular relaxation process, the dielectric loss is expected to become thickness dependent.

SCALP THICKNESS AND THE FAT-LOSS THEORY OF BALDING
Archives of Dermatology, 1954OF THE various hypotheses advanced to account for male pattern balding, most have been rendered untenable by the simple demonstration that testicular hormones are a prerequisite for the common patterned alopecia of the male. As shown by Hamilton, castrate or eunuchoid males are free from pattern balding, while testosterone can induce hair fall in ...

Hearing Loss in Children with Abnormal Corneal Thickness
International Journal of Audiology, 1982Corneometry, i.e. measurement of the thickness of the centre of cornea, has been introduced as an objective method for the diagnosis of ecto-mesodermal insufficiency. A group of children, between 4 and 18 years of age with different types of hearing defects has been examined by this method and the results were evaluated separately for conductive and ...

Energy Loss Straggling of Protons in Thick Absorbers
Nuclear Instruments and Methods, 1976The energy loss of charged particles transmitted through an absorber is subject to fluctuations due to the statistical nature of the excitation and ionization processes involved. For an initially monoenergetic beam of charged particles incident on an absorber of uniform thickness there will be an energy distribution function associated with the ...

Automated Measurement of Corrosion Thickness and Metal Loss
Offshore Technology Conference, 2022Abstract If not closely monitored, corrosion on the surface of offshore oil and gas platforms leads to the increased risk of unplanned shutdowns. On-site fabric maintenance inspections of corrosion defects are labor-intensive and require frequent travel offshore.

Thick Flames with Localised Heat Loss
Combustion Science and Technology, 1990Abstract The solution of the one-dimensional premixed flame equations is considered with Arrhenius kinetics, not only with the assumption of large activation energy, but also large heat release. Previous studies have shown that under these circumstances, the chemical zone widens considerably with the pre-heat zone no longer able to be modelled as a ...

Water loss and the origin of thick ultramylonites
Geology, 2016<p>Hydrolytic weakening has been suggested as a major process facilitating strain localisation, consistent with many studies that have found a positive correlation between water content and intensity of deformation. We examine the role of water in an unusually thick shear zone: the 1 km-thick ultramylonitic layer of the El Pichao shear ...

Thickness dependence of dielectric losses in TGSe
Ferroelectrics, 1996Abstract Dielectric losses in TGSe were measured in the frequency range from 20 Hz to 1 MHz for various thicknesses. Domain wall relaxation frequencies decrease with increasing sample thickness. Temperature dependence of the domain wall relaxation frequency was also analysed.

The Thickness Dependence of Energy Loss Spectra
Proceedings, annual meeting, Electron Microscopy Society of America, 1982One factor limiting energy loss analysis is the effect of multiple scattering on core loss edge shapes. Multiple scattering distorts fine structures, leads to incorrect quantitative analyses and even affects analysis of extended fine structure (EXELFS).

Transmission Loss of Thick-Film Microstriplines
IEEE Transactions on Microwave Theory and Techniques, 1982Thick-film microstripline transmission loss is measured and discussed, and an empirical formula for thick-film microstripline transmission loss is obtained. It is found that the transmission loss of copper thick film is nearly equal to that of thin film for frequencies up to 10 GHz.
