Effects of nutrients on the primary production and determination of the restricting factors in primary production in the international wetland of Choghakhor (Iran)
Limitations in nutrients and physicochemical parameters play a key role in aquatic ecosystems. The present study aimed to determine the influential physicochemical factors in the chlorophyll-a content for wetland management by identifying the restricting factors in primary production. Sampling was conducted during March 2017-February 2018. Factors such as water salinity, temperature, pH, nitrat...
متن کاملRecovery of Methyl Acetoacetate from Antibiotic Production Plant\'s Waste Streams (TECHNICAL NOTE)
Chemical recovery of methyl acetoacetate from the amoxicillin plant’s waste stream was investigated. In process of amoxicillin production for activation of amoxicillin molecule, hydrolysis takes place at final stage. As a result methyl acetoacetate is formed. Liquid-liquid extraction was employed for the recovery of methyl acetoacetate from the waste stream. Diluted alkaline solution was used a...
متن کاملLaboratory medicine in primary health care.
A LTHOUGH simple laboratory tests have been performed At'1.in primary health care for many years, recent technological developments have made it possible to do a much wider range of tests nearer the patient ('near patient testing').'-3 Many of these tests require little equipment and a non-technical person such as a nurse can often obtain a result within a few minutes. In the United States at l...
متن کاملPrimary productivity in receiving reservoirs: links to influent streams
Primary productivity and chlorophyll a concentrations were measured in 8 reservoirs in New York City drinking-water-supply watersheds. The light-and-dark bottle O2-change procedure was used to measure gross primary productivity (GPP) once each summer from 2000 to 2002. GPP normalized for photosynthetically active radiation (PAR) in the Neversink and Schoharie averaged only 0.025 and 0.035 g O2/...
متن کاملPrimary Follicular Lymphoma of the Conjunctiva in a 12 Year-Old Male
Abstract Background Follicular lymphoma (FL) is the second most common adnexal lymphoma of the eye that almost all of them are reported in elderly patients. Primary FL of the eye has been reported in only two children. Pediatric FL appears to be biologically distinct from typical adult FL. In cases without other organ involvement excision alone with close monitoring is a treatment of choic...
