Although nitrogen (N) deposition is a significant threat to herbaceous plant biodiversity worldwide, it is not a new stressor for many developed regions. Only recently has it become possible to estimate historical impacts nationally for the United States. We used 26 years (1985-2010) of deposition data, with ecosystem-specific functional responses from local field experiments and a national cri...

Cattle consuming bahiagrass pastures in Florida are often deficient in crude protein. The purpose of this study was to observe the effects of two protein supplements (Urea and Optigen) as compared to cows receiving no protein supplementation (Control) while consuming bahiagrass hay. Optigen II® (Alltech, Inc., Nicholasville, KY) is a slow-release nitrogen source. The delayed availability of nit...

BACKGROUND AND AIM Data on quantitative metabolic liver functions in the life-threatening disease alcoholic hepatitis are scarce. Urea synthesis is an essential metabolic liver function that plays a key regulatory role in nitrogen homeostasis. The urea synthesis capacity decreases in patients with compromised liver function, whereas it increases in patients with inflammation. Alcoholic hepatiti...

To evaluate the effects of treating or supplementing common reed (Phragmites australis) with 2% urea on intake, nutrient apparent digestibility, and blood metabolites, fifteen Baluchi rams (35.4±2.3 kg body weight) were used in a completely randomized design. Treatments were as follows: 1) common reed, 2) common reed supplemented with 2% urea solution at feeding, and 3) common reed tre...

INTRODUCTION The manure policy is one of the most important environmental policies in the Flemish agricultural sector. The first version of the manure decree was introduced in 1991 as a result of the introduction of the European Nitrate directive (91/676/EEC). The goal is to protect groundand surface water against nitrogen pollution out of agricultural sources. Since its introduction, the manur...

We describe a one-step, deterministic and scalable scheme for creating macroscopic arbitrary entangled coherent states (ECSs) of separate nitrogen-vacancy center ensembles (NVEs) that couple to a superconducting flux qubit. We discuss how to generate the entangled states between the flux qubit and two NVEs by the resonant driving. Then the ECSs of the NVEs can be obtained by projecting the flux...

We propose a method to achieve coherent coupling between nitrogen-vacancy (NV) centers in diamond and superconducting (SC) flux qubits. The resulting coupling can be used to create a coherent interaction between the spin states of distant NV centers mediated by the flux qubit. Furthermore, the magnetic coupling can be used to achieve a coherent transfer of quantum information between the flux q...

Transition metal catalyzed denitrogenative transannulation of a triazole ring has recently received considerable attention as a new concept for the construction of diverse nitrogen-containing heterocyclic cores. This method allows a single-step synthesis of complex nitrogen heterocycles from easily available and cheap triazole precursors. In this Minireview, recent progress of the transition me...
