Money Doctoring After World War II: Arthur I. Bloomfield and the Federal Reserve Missions to South Korea

2009

In this paper we analyse the scientific contributions of the New York Fed economist Arthur I. Bloomfield. A Canadian born economist, in 1941 Bloomfield took his PhD in economics at the University of Chicago, under the supervision of Jacob Viner and then joined the staff of the Federal Reserve Bank of New York as a Research Economist and stayed there until 1958. In this position, Bloomfield combined scholarly research on recent economic history and international financial and banking problems with active service as a member of various committees and commissions, both in the United States and abroad. While on leave from the Fed, he accepted appointments as a consultant and advisor to various …

Effect of cladode shading on growth and ripening of fruits of cactus pear (Opuntia ficus-indicaL. Miller)

1997

SummaryFruiting cladodes of O. ficus-indica were covered with shade nets at different stages of the fruit development period to study the effect of the time and duration of shade on fruit growth, ripening time and harvest quality. Shading the fruiting cladodes 0, 15 and 30 d after full bloom (DAB) for a period of 15, 30, 45, 60 or 75 d significantly reduced fruit growth and ultimate harvest size. The longer the shading period the greater was the reduction of harvest fruit size. The greatest reduction of fruit growth (30%) occurred when the fruiting cladodes were shaded from bloom to harvest. Differences in growth rate beween fruits on shaded or sunlit cladodes begun to appear at 30 DAB and …

Trophic Status of the South-Eastern Baltic Sea: A Comparison of Coastal and Open Areas

2001

Primary production, nutrient concentrations, phytoplankton biomass (incl. chlorophyll a) and water transparency (Secchi depth), are important indicators of eutrophication. Earlier basin-wide primary production estimates for the Baltic Sea, a shallow shelf sea, were based mainly on open-sea data, neglecting the fundamentally different conditions in the large river plumes, which might have substantially higher production. Mean values of the period 1993–1997 of nutrient concentrations (phosphate, nitrate, ammonium and silicate), phytoplankton biomass, chlorophyll a (chl a) concentration, turbidity and primary production were calculated in the plumes of the rivers Oder, Vistula and Daugava and …

Use of the preliminary Jedlice Reservoir for water protection in the Turawa Reservoir on the Mała Panew River

2009

Abstract Physico-chemical variables of water quality and benthic community structure were assessed in order to evaluate the need for reinstating the use of the preliminary Jedlice Reservoir. The waters of the Mała Panew River carry a significant load of nutrient compounds, particularly nitrates and phosphates. Deteriorating water quality results in permanent algal blooms and changes in the macrofauna structure. It was confirmed that the use of a preliminary reservoir could contribute to the protection of the Turawa Dam Reservoir against pollutants transported by the waters of the Mała Panew River.

Long-term land-based and internal forcing of the nutrient state of the Gulf of Riga (Baltic Sea)

2004

Abstract The long-term nutrient trends (N, P, Si) in the Gulf of Riga and their driving factors were studied based on monitoring data from 1974 to 2000. Each nutrient showed individual temporal behaviour. The nitrate-N pool peaked in 1989–1990, but after that, the increasing trend switched to a decrease. The P pool, in turn, constantly increased till the mid-1990s; afterwards, a tendency was unclear. The obvious depletion of the silicate-Si pool reversed after 1995. Algal growth limitation responded to the changes in the nutrient pool. P deficiency during the vernal phytoplankton bloom in 1979–1990 switched to further alternate P or N limitation or co-limitation. Since 1991, Si shortage set…

Gross Primary Production and false spring: a spatio-temporal analysis

2020

<p>Phenological information can be obtained from different sources of data. For instance, from remote sensing data or products and from models driven by weather variables. The former typically allows analyzing land surface phenology whereas the latter provide plant phenological information. Analyzing relationships between both sources of data allows us to understand the impact of climate change on vegetation over space and time. For example, the onset of spring is advanced or delayed by changes in the climate. These alterations affect plant productivity and animal migrations.</p><p>Spring onset monitoring is supported by the Extended Spring Index (…

Welfare status of cage farmed European sea bass (Dicentrarchus labrax): A comparison between submerged and surface cages

2011

Abstract Submersible sea-cages represent an alternative method to standard surface-based cages, and could help solve several production problems that exist in surface-based farming, such as heavy storms, algal and jellyfish blooms and attacks by predators. In this study, we investigated growth, haematological, biochemical and immunological parameters of European sea bass ( Dicentrarchus labrax ) farmed in surface and submersible cages, to compare the physiological status under different rearing conditions. In addition, we evaluated the use of erythrocyte HSP70 levels as a biomarker of fish welfare. The study was conducted in two submerged and two surface cages filled with D. labrax . No sig…
