Abstract We demonstrate coherent storage and retrieval of pulsed light using the atomic frequency comb protocol in a room temperature alkali vapor. We utilize velocity-selective optical pumping to prepare multiple velocity classes in the $F = 4$ hyperfine ground state of cesium.
The acute response profile of inflammatory and oxidative stress biomarkers in welders Abstract Objectives: Welding fume is an occupational hazard that can cause a variety of health effects. We aimed to investigate inflammatory response profile and oxidative stress level after acute welding fume exposure.
Total joint arthroplasty is associated with blood loss and a fall in the haemoglobin level. Need for blood transfusion postoperatively is associated with multiple hazards, including transfusion reactions resulting in potential lung injury or exposure to blood-borne pathogens and potential infection.1–4 Therefore, actions to reduce blood loss are important.
Alkali-resistant glass fibers (ARG) which are designed to reinforce cementitious and other alkali containing materials are coated with special sizings to provide superior alkali resistance. To determine how the environment affects the fiber surface properties and in turn mechanical behavior, two kinds of ARG fibers with different percentage of zirconia, namely NEG and CemFIL were subjected to various treatments and single fiber tensile tests.
