TL;DR: The temperature elevation under the current guideline for occupational exposure is within the ranges of brain temperature variability for environmental changes in daily life and the effect of vasodilation is significant, especially at higher frequencies where skin temperature elevation is dominant.
Abstract: Two international guidelines/standards for human protection from electromagnetic fields define the specific absorption rate (SAR) averaged over 10 g of tissue as a metric for protection against localized radio frequency field exposure due to portable devices operating below 3–10 GHz. Temperature elevation is suggested to be a dominant effect for exposure at frequencies higher than 100 kHz. No previous studies have evaluated temperature elevation in the human head for local exposure considering thermoregulation. This study aims to discuss the temperature elevation in a human head model considering vasodilation, to discuss the conservativeness of the current limit. This study computes the temperature elevations in an anatomical human head model exposed to radiation from a dipole antenna and truncated plane waves at 300 MHz–10GHz. The SARs in the human model are first computed using a finite-difference time-domain method. The temperature elevation is calculated by solving the bioheat transfer equation by considering the thermoregulation that simulates the vasodilation. The maximum temperature elevation in the brain appeared around its periphery. At exposures with higher intensity, the temperature elevation became larger and reached around 40 °C at the peak SAR of 100 W/kg, and became lower at higher frequencies. The temperature elevation in the brain at the current limit of 10 W/kg is at most 0.93 °C. The effect of vasodilation became notable for tissue temperature elevations higher than 1–2 °C and for an SAR of 10 W/kg. The temperature at the periphery was below the basal brain temperature (37 °C). The temperature elevation under the current guideline for occupational exposure is within the ranges of brain temperature variability for environmental changes in daily life. The effect of vasodilation is significant, especially at higher frequencies where skin temperature elevation is dominant.

TL;DR: In this article, the authors comprehensively study assembly process design to handle variety and present a new approach to strategically manage manufacturing complexities because of product varieties, linking the chronological steps of APD to a general approach with a view to reduce both short and long term wastes.
Abstract: This paper comprehensively studies assembly process design (APD) to handle variety and presents a new approach to strategically manage manufacturing complexities because of product varieties. It links the chronological steps of APD to a general approach with a view to reduce both short and long term wastes. It synthesizes two strategic approaches, product and process-based, while exploiting the APD of an entire product family. A new evaluation method for measuring the complexities of an assembly system at different stages of design has been introduced by applying information entropy. The developed evaluation methodology explains the available techniques related to design, interprets them from a design for variety point of view, and leads to techniques to manage complexities in manufacturing. The suggested methodology has been applied to examples from automobile part manufacturers and has been found to be effective in understanding the complexities in manufacturing and leading to some strategies to manage variety.

TL;DR: In this paper, the dispersion relation for sound in rarefied polyatomic gases (hydrogen, deuterium and hydrogen deuteride gases) is studied based on the recently developed theory of extended thermodynamics (ET) of dense gases.
Abstract: We study the dispersion relation for sound in rarefied polyatomic gases (hydrogen, deuterium and hydrogen deuteride gases) basing on the recently developed theory of extended thermodynamics (ET) of dense gases. We compare the relation with those obtained in experiments and by the classical Navier–Stokes Fourier (NSF) theory. The applicable frequency range of the ET theory is proved to be much wider than that of the NSF theory. We evaluate the values of the bulk viscosity and the relaxation times involved in nonequilibrium processes. The relaxation time related to the dynamic pressure has a possibility to become much larger than the other relaxation times related to the shear stress and the heat flux.

TL;DR: Results indicate that the His-tag successfully controlled the orientation of the RC on the solid substrate, and that the RC produced photocurrent depending upon the orientation on the electrode.
