Role and procedures of natural resources accounting (NRA) : an NRA framework for Botswana
This paper aims to show the role that NRA can play in environmental and economic accounting, and the procedures that need to be followed when carrying out natural resources accounting. The paper first reviews the SNA and its shortcomings regarding the treatment of the environment and natural …

Representing the American rifleman: how the NRA built and maintained a national community of gun owners
… as the National Rifle Association of America (NRA). The NRA is a powerful force in conservative politics, “gun rights” lobbying, and the wider “gun culture.” It makes meaning and provides political access for millions of American gun owners. Previous scholarship on the NRA has tended to neglect …

Divergent Phenotypic Recurrent Selection for Nitrate Reductase Activity and Correlated Responses in Maize
… for post anthesis nitrate reductase activity (NRA) in maize was conducted through three cycles. The original material (C(,0)) was the maize (Zea mays L.) synthetic, Super Stiff Stalk Synthetic. The primary objectives were to determine: the selection response of NRA and the correlated responses …

Nitrate Reductase Activity, Nitrate Uptake and Iodine Speciation in the Marine Environment
… by measuring the activity of nitrate reductase (NRA). In addition, because it has long been suspected that the biological reduction of IO<sub>3</sub><sup>–</sup> to I<sup>–</sup> may be mediated by nitrate reductase (NR), this research investigated the ability of NR to catalyze the reduction of …

Leaf Lamina Reduced Nitrogen Concentration and Nitrate Reductase Activity as Criteria for the Identification of Productive Maize Genotypes
Leaf lamina nitrate reductase activity (NRA), and total reduced nitrogen concentration (TRNC) in maize (Zea mays L.) were examined for relationships to grain yield, yield components, grain protein, maturity, and soil nitrogen fertility (N). Genotypes were classed as high and low for NRA (HNRA and …

Design and analysis of pattern null reconfigurable antennas
… of pattern null reconfigurable antennas (NRAs). Unlike conventional pattern reconfigurable antennas, NRAs possess the ability to steer their pattern nulls, yielding interference rejection capabilities. While various NRAs exist, the current state of the art has two significant drawbacks, …

Economic Revolution From Within: Herbert Hoover, Franklin Delano Roosevelt And The Emergence Of The National Industrial Recovery Act Of 1933
… to place the National Recovery Administration (NRA), a central agency of Franklin D. Roosevelt’s New Deal, in historical context. It explores the NRA’s origins in the political agendas and ideological arguments of presidents Herbert Hoover and Franklin Delano Roosevelt as they reshaped the …

Reluctant realists: the Pacific Northwest lumber industry, federal labor standards and union legislation during the New Deal
… structure. The National Recovery Administration (NRA) similarly failed to provide a disciplined framework for competition in the region because the federal government failed to fulfill its role as an enforcement agent, although the experience of the NRA did suggest to the industry the potential …

The Effect of the Site of Nitrogen Assimilation on Plant Growth
… tobacco gene resulted in greater alterations in NRA than the transformation of the corresponding double mutant. Changes in growth and co-suppression-like leaf chlorosis was the most frequent outcome, often causing a lowering or disappearance of NRA. A negative correlation between the ratio of …

Interactive Learning and Generalization in Repeated Games: Theories, Models, and Experiments
… I propose the concept of Net Reward Attractions (NRA) equilibrium and test its predictive accuracy on data from experiments on 26 repeated, completely mixed games run under full-feedback condition. Moreover, I compare NRAâ€TMs predictive power with that of other five equilibrium concepts and …

A novel measurment of net erosion and plasma-material interaction in plasma thrusters
… wall material. Nuclear Reaction Analysis (NRA) on the implanted material gives net erosion measurements while simultaneous Rutherford Backscattering Spectroscopy (RBS) quantifies the plasma retention and contamination in the surface layers. This insight into the surface composition and PMI …
