Measurements of the hemispherical-directional reflectance of snow at fine spectral and angular resolution [PDF]
Journal of Geophysical Research, 2004 We present 2 days' measurements of the hemispherical‐directional reflectance factor (HDRF) of snow made at fine spectral and angular resolution with the Automated Spectro‐Goniometer (ASG) for the range of solar zenith angles (θ0 = 40°–50°) and snow textures (surface grain size = 80–280 μm).

Foods, 2022 Food product packaging should block light to protect nutrients, color and active ingredients in functional food from degradation. Currently, packages are not optimized in terms of the solar radiation impact on the products they contain. The aim of this study was to develop a method of quantifying the interaction of food products with solar radiation ...

Applied Sciences (Switzerland)Sesame oil has been widely used for centuries. It is not only used as a kitchen ingredient, but it is also used to apply to the skin. Sesame oil contains natural compounds such as sesamol, sesamolin and sesamide, which have the ability to reflect or absorb certain UV rays.

Directional Hemispherical Reflectance as a Quick Method for Analysis of Degradation Processes in Commercial Effervescent Tablets [PDF]
ASEC 2022, 2022 In the present study, we aimed to evaluate the total directional hemispherical reflectance (THR) in expired and unexpired effervescent tablets. Expired tablets were stored in ambient conditions. The THR was measured using a SOC-410 Directional Hemispherical Reflectometer (Surface Optics Corporation, San Diego, CA, USA) in seven wavelength bands from ...

Clinical, Cosmetic and Investigational Dermatology, 2023 Infrared radiation (IR) has a wide spectrum of both positive and harmful effects on the human body. Negative properties, manifested by increasing the level of reactive oxygen species (ROS), affect the skin ageing acceleration. Other adverse effect of infrared exposure is related to its ability to significantly penetrate deep into the skin, between its ...

Normal-directional and normal-hemispherical reflectances of micron- and submicron-sized powder beds at 633 and 790nm [PDF]
Journal of Applied Physics, 2006 A conic pyroelectric detector is employed to measure the effective reflectances of powder beds of metals, SiC, WC, and graphite. The experimental results are compared with numerical solutions of the radiation transfer equation in a half-infinite homogeneous body with effective radiative properties.
