These individuals, who had already contracted the disease, recovered and became “immune” or “exempt.” However, the earliest recognized attempt to intentionally induce immunity to an infectious disease was...

Using Fluorescence Spectrometer Lumina, fluorescence spectra of surface slices apples and potatoes were measured. Some the samples healthy, some infected: had scabs, rot mechanical damage. For apples, two zones found where emission healthy scab-affected differed significantly from each other. This is region 400–450 nm with excitation 300–350 nm, as well 680–750 nm. potatoes, differences between...

This paper provides a case study of the effect of labor relations on product quality. We consider whether a long, contentious strike and the hiring of replacement workers at Bridgestone/Firestone’s Decatur plant in the mid-1990s contributed to the production of defective tires. Using several independent data sources, and looking before and after the strike and across plants, we find that labor ...

This is mainly evident at the level of the epidermis and the upper papillary dermis, with a tissue laxity and skin that appears more lined, often accompanied by telangiectasias, wrinkles, and dark spots. Resurfacing with ultra-pulsed CO2 ...
