A pyrometer system is an optically passive, non-intrusive method that uses thermal radiation law to determine temperature. It combines electronic and optical instruments to detect low-level signals of radiation measurements. Surface high-temperature measurements are successfully obtained using a two-wavelength pyrometer system.

Ethylene Glycol (EG) and diethylene Glycol (DEG) are two contaminants known to cause various human health problems. These glycols might be present in drug syrups that are based on glycerol, sorbitol, or polyethylene glycol. In late 2022, several batches of cough, antipyretics, and antihistamine syrups were reported to contain toxic levels of EG and DEG in multiple countries; this incident concerned the World Health Organization (WHO).

Carbon fiber-reinforced polymers are considered a promising composite for many industrial applications including in the automation, renewable energy, and aerospace industries. They exhibit exceptional properties such as a high strength-to-weight ratio and high wear resistance and stiffness, which give them an advantage over other conventional materials such as metals. Various polymers can be used as matrices such as thermosetting, thermoplastic, and elastomers polymers.

Objectives: To explore implicit stereotyping among primary healthcare (PHC) physicians and to identify determinants of physicians' stereotyping of patients based on the patients' characteristics and appearance.

Methods: This study followed an analytical cross-sectional design conducted between October 2019 and December 2019, and included 250 primary healthcare (PHC) physicians in Aseer Region, Kingdom of Saudi Arabia. Data was collected using a self-administered questionnaire, which included items concerning physicians' sociodemographic characteristics, and their attitudes toward patient characteristics and patient appearance.

Hypothesis: For a wide range of subsurface engineering processes, such as geological carbon sequestration and enhanced oil recovery, it is critical to understand multiphase flow at a fundamental level. To this end, geomaterial microfluidic devices provide visual data that can be quantified to explain the physics of multiphase flow at the length scale of individual pores in realistic rock structures. For surfactant enhanced oil recovery, it is the underlying geometrical states of the capillary trapped oil that dictates the recovery process and the degree to which oil is recovered through either mobilization or solubilization during in situ emulsification.
