PHYTOPLANKTON PRIMARY PRODUCTIVITY
Ukrainian Journal of Natural Sciences, 2023Primary productivity is an important integral parameter describing energy potential of aquatic organisms’ vital activity. Primary productivity determines the quality of water environment, its selfpurifying capacity – from the Global Ocean to various continental ecosystems (Odum 1953, Williams et al. 2002, Bott et al.

Primary Productivity in the Golden Horn
Environmental Monitoring and Assessment, 2005The shores of the Golden Horn--once most important seaport of the region--represented throughout history a romantic and recreational venue. This tributary to the Bosphorus, however, became seriously polluted with the extensive industrialization and rapid population growth in Istanbul over the past century.

Primary production and primary producers
1996The distribution of plant species and their productivity in a fluvial hydro-system is dependent on the complex interactions between hydrodynamic processes (e.g. flow velocity, shear stress, the nature and stability of the substrate etc.), hydrochemical processes (e.g.

The production of biomass by plants is of central importance to energy, carbon, and nutrient fluxes in ecosystems. Knowledge of the spatial and temporal variation of production and the underlying biotic and physical controls on this variation are central themes in ecosystem science.

Natural Product Primary Sulfonamides and Primary Sulfamates
Journal of Natural Products, 2015Primary sulfonamide and primary sulfamate functional groups feature prominently in the structures of U.S. FDA-approved drugs. However, the natural product chemical space contains few examples of these well-known zinc-binding chemotypes, with just two primary sulfonamide and five primary sulfamate natural products isolated and characterized to date. One

Primary production in the Patuxent River
Chesapeake Science, 1965Rates of production were measured at 22 stations located in a 29-mile segment of the Patuxent River Estuary. The river was sampled in mid-stream at 12 stations which were distributed from a point near solomons, Maryland, to Milltown Landing upstream. Thirteen of the stations were arranged in three transects, which spanned the river in the vicinity of ...

The primary production of the phytoplankton is one of the most important sources of the energy input in freshwater ecosystems (Moss 1980). A broad knowledge of endogenous and exogenous control mechanisms of phytoplanktonic primary production is necessary to obtain basic information on the energy flow in the ecosystem of Lake Stechlin.

Interferon production in primary immunodeficiencies
Journal of Clinical Immunology, 1984Alpha- and gamma-interferon (IFN) production by peripheral blood mononuclear cells (PBMC) from 18 patients affected by primary immunodeficiency syndromes was examined and compared with that of 20 normal donors. Patients included 8 with common variable immunodeficiency (CVI), 2 with congenital agammaglobulinemia, 4 with ataxia-telangiectasia, 2 with ...

The primary acid product of DPNH
Biochemical and Biophysical Research Communications, 1973Abstract Analysis of the proton magnetic resonance spectra obtained at 220 MHz confirms the axial conformation of the C-6 hydroxyl in the model primary acid product 1-n-(2,6-dichlorobenzyl)-6-hydroxy-1,4,5,6-tetrahydronicotinamide. In the primary acid product of DPNH however the reaction occurs stereospecifically with the substitution at the C-6 ...
