An autonomous nutrient analyzer for oceanic long-term in situ biogeochemical monitoring.
An autonomous nutrient analyzer in situ (ANAIS) has been developed to monitor nitrate, silicate, and phosphate concentrations while deployed at sea at pressure (down to 1000 m). Detection is made by spectrophotometry. The instrument uses solenoid-driven diaphragm pumps to propel the sample, the standards, and the reagents through a microconduit, flow injection-style thermostated manifold. The a...
متن کاملHealth technology assessment in Iran: Barriers and solutions
Background: Health technology assessment (HTA) is a tool utilized for efficient dissemination of technology. For the purpose of encouraging decision-makers to utilize this tool, at first, we need to identify the obstacles in the processes of preparation, utilization, and implementation of HTAs. This study aims to define these barriers and offer solutions for effective utilization of HTA reports...
متن کاملNutrient Solutions for Hydroponic Systems
Among factors affecting hydroponic production systems, the nutrient solution is considered to be one of the most important determining factors of crop yield and quality. This chapter aims to explain aspects related to plant nutrition and its effects on production of hydroponic crops, considering basic aspects such as nutrient solutions and their development through the years; components of nutr...
متن کاملChelation of Trace Metals in Nutrient Solutions.
Plant nutrition studies frequently require nearly complete elimination of trace metals from the nutrient media in which the plants are to be grown. Conventional methods of purification by recrystallization and precipitation have been used for this purpose in some studies. These have proved more difficult and less effective than the adsorption technique developed by STEINBERG (11) and improved b...
متن کاملMars In Situ Resource Utilization Technology Evaluation
We have examined the technologies required to enable Mars In-Situ Resource Utilization (ISRU) because our understanding of Mars resources has changed significantly in the last five years as a result of recent robotic missions to the red planet. Two major developments, (1) confirmation of the presence of near-surface water in the form of ice in very large amounts at high latitudes by the Phoenix...
