This article discusses the Hebrew word מָאוֹר, which is often rendered by `light, lamp'. It is suggested to render the word consistently as `light', whereas it may be interpreted in several cases as an abstractum pro concreto, thus `light source'. The paper is published at the website of the Semantics of Ancient Hebrew Database (SAHD): http://sahd-online.com/.
This work presents the results of a two-stage (carbon fixation and hydrogen production) experimental study for hydrogen production from microalgae using optical fiber as an internal light source. Effect of absence and presence of light on... more

On one hand, urban lighting expresses itself in a complex visual environment made by the interplay by between many separate lighting schemes, as street lighting, shop lighting, luminous commercials etc. On the other, a noticeable order of patterns occurs, when lighting is observed as luminous formation and rhythm. When integrated into an architectural concept, electrical lighting non-intended for poetic composition has the ability to contribute to place, time, and function-telling aspects of places in urban contexts. Urban environments are information wise challenging to pre-historic human instincts, but they can be met by careful selection and adjustment of existing light situations.

The project drew on Argonne's experience building and operating superconducting undulators and Berkeley and Fermilab's knowledge of niobium-3 tin. [37] Researchers from Würzburg and London have succeeded in controlling the coupling of light and matter at room temperature. [36] Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging and Light Detection and Ranging (LIDAR) systems that scan the surroundings of self-driving cars and trucks. [35] The unique platform, which is referred as a 4-D microscope, combines the sensitivity and high time-resolution of phase imaging with the specificity and high spatial resolution of fluorescence microscopy.

La luz es omnipresente en nuestras vidas. Con la luz vemos, ya sea gracias a la luzdel sol o gracias a la luz producida artificialmente mediante aparatos creados por el ser humano. Con la luz estáis leyendo estas palabras. Mirad a vuestro alrededor: si es de día, estará todo inundado por la luz del sol; si es de noche,veréis incontables aparatos que también producen luz. ¿Cómo se produce todaesta luz? Esta es la pregunta que quiere responder este libro. Pretende explicar cuáles son los mecanismos físicos por los cuales se puede producir luz y cómo funcionan las diversas fuentes de luz que existen, haciendo especial hincapié en el láser, por sus especiales características.
