Food Chemistry International, EarlyView.Gac fruit's high carotenoid content, especially in the aril, makes it an excellent natural red pigment source for food applications, offering a safer alternative to synthetic dyes. Ethanol extraction achieved the highest overall pigment recovery (89.53%), whereas ethyl lactate extraction yielded the highest levels of total carotenoids, β‐carotene ...

FlexMat, EarlyView.A carbon‐quantum‐dots (CQDs)‐based programmable luminescent platform is proposed for multidimensional optical information encryption and high‐capacity data storage by leveraging wavelength‐division multiplexing. Furthermore, a prototype tri‐layer optical disk is demonstrated, where data written via laser ablation on different CQD layers are retrieved ...

A case of momentary exposure of the right hand to irradiation from a microwave oven is described. Transient paresthesias and a cold, pale hand resulted but resolved spontaneously in 60 minutes without treatment. Even momentary exposure can result in severe coagulation necrosis, with eventual loss of the exposed extremity.

The cosmic microwave background radiation
Reviews of Modern Physics, 1979Radio Astronomy has added greatly to our understanding of the structure and dynamics of the universe. The cosmic microwave background radiation, considered a relic of the explosion at the beginning of the universe some 18 billion years ago, is one of the most powerful aids in determining these features of the universe. This paper is about the discovery

Cosmic Microwave Background Radiation
Reviews of Modern Physics, 1999Most astronomers and physicists now believe that we live in an expanding universe that evolved from an early state of extremely high density and temperature. Measurements of the spectrum and anisotropy of the cosmic microwave background radiation (CMBR) provide strong evidence supporting this picture. Today, the spectrum of the CMBR matches that of a 2.

Radar was made possible by development of the magnetron oscillator tube. Radar was one of the closely guarded secrets during the war. Now, with the ending of hostilities, its field of usefulness has been extended into the field of medicine. The Raytheon microtherm, which generates energy in a continuous wave, air-cooled magnetron oscillator tube, is ...
