Automation of a plane grating spectrograph
A Zeiss model PGS-2 plane grating spectrograph was automated by replacing its photograph film detection system with an EGG-Reticon 1024S photodiode array (PDA) and by controlling the main instrument functions through the use of a home-made interface connected to a microcomputer. The array was cooled by four Peltier elements to allow integration of the emitted light for up to 40 s. The interface...
متن کاملA slit grating spectrograph for quantitative soft x-ray spectroscopy
In this article we describe a new slit grating spectrograph which is based on an e-beam written 10 000 linepairs/mm freestanding transmission diffraction grating. In combination with a thinned, back-illuminated charge coupled device ~CCD!, the spectrograph allows for real-time spectroscopy of laser-produced plasma x-ray sources within the wavelength region l51–20 nm. Calibration of grating and ...
متن کاملNonruminant Nutrition: Mineral-Mineral Interactions: Implications for Nutrition
Inorganic elements (metals, non-metals, transition elements, and electrolytes commonly called “minerals” in nutrition science) are critical to all life processes as enzyme cofactors, stabilizers of proteins, structural components of tissues, second messengers, regulators of acid-base balance, participants in redox reactions, and for the maintenance of cellular electrical potential. For this rea...
متن کاملNonruminant Nutrition: Mineral Nutrition
Calcium formate (CaFo; Rovelan–Lanxess Corporation, Germany) is a commonly used source of calcium in poultry and swine feed in the EU. Due to increased cost, US interest in alternate feedstuffs has grown. The objective of this study was to evaluate CaFo in broiler diets as an alternate calcium source during a 49d pen trial. A total of 2,160 male Cobb 500 broilers were randomized and placed in 4...

F or normal growth and optimum production, fruit the quantities that they are in certain annual crops. Generally, nitrogen is the only macronutrient that must be consistently supplied to fruit trees in California. Under certain conditions, other nutrient deficiencies can develop. Toxicities can also become a problem. These will be discussed in the sections for individual nutrients. trees requir...
