Suitability of Selenate Containing Silage Additives for the Supply of Beef Cattle [PDF]
, 2023 Selenium concentrations in herbage are frequently insufficient (\u3c 100 μg Se/kg dry matter (DM)) to meet the requirements of ruminants. Whereas increasing Se supply by feeding mineral mixtures is a reliable method to prevent Se deficiencies for dairy ...

Indian Journal of Ophthalmology, 2018 A 64-year-old male patient presented to the clinic with diminished vision in his right eye for the past 2 years. Examination revealed a best-corrected visual acuity (BCVA) of counting fingers at 1 m with a scarred choroidal neovascular membrane (CNVM) in the right eye while the left eye had a BCVA of 20/20 with a small peripapillary subretinal ...

Longitudinal Laser Shaping in Laser Wakefield Accelerators [PDF]
Phys.Lett.A296:125-130,2002, 2000 We study the energetics of wake excitation during the laser-plasma interaction in application to laser wakefield accelerators. We find that both the wake amplitude and the accelerating efficiency (transformer ratio) can be maximized by properly shaping the longitudinal profile of the driving laser pulse.

Unresonant interaction of laser beams with microdroplets [PDF]
Journal of the European Optical Society-Rapid Publications, 2012 The interaction of distilled water droplets (volumes of 3-4 µl) with pulsed laser beams emitted at 532 nm is described. At 532 nm the distilled water absorption is very low and the interaction of a water droplet with the laser radiation is dominated by ...

Thermal photon statistics in laser light above threshold [PDF]
Phys.Rev. A62 (2000) 063807, 1999 We show that the reduction in photon number fluctuations at laser threshold often cited as a fundamental laser property does not occur in typical semiconductor lasers such as the ones commonly used in modern technological applications today. Indeed, such lasers may still exhibit thermal intensity fluctuations far above threshold.

Rethinking Patent Law\u27s Exclusive Appellate Jurisdiction [PDF]
, 2022 The United States Court of Appeals for the Federal Circuit was created in 1982 to unify and clarify patent law, inter alia. It was built from political compromise after the Hruska Commission, which studied the caseload crisis in the federal appellate ...

Rod Laser – The first laser was a rod laser [PDF]
Laser Technik Journal, 2005 Laser technology is relatively young. The first laser was built in 1960 by Maiman at AT&T Labs in the USA. It was a rod-shaped ruby laser, this arrangement having been chosen for its favourable symmetry (Fig. 1). Starting from this device, the technology of solid-state lasers developed rapidly.
