Opuntia ficus-indica (Prickly pear cactus) is a large succulent cactus species that has a long history of agricultural production for carmine dye, fruits, and edible young cladodes. As a CAM plant O. ficus-indica uses crassulacean acid metabolism (CAM) which is characterized by …

Public concern over groundwater quality has grown significantly in recent years and has focused increasingly on agriculture as a source of groundwater quality problems. Increasing evidence of nitrate contamination of groundwater beyond the maximum contaminant level has intensifi…
Nitrate contamination of surface and groundwater has become a serious concern in many agricultural areas throughout the world. The major source of nitrate contamination is believed to be nitrogen fertilizer from agricultural fields. Best Management Practices have been developed …
Introduction and aim: Increases in the bioavailability of nitric oxide have been shown to reduce the oxygen (O2) cost of exercise, improve exercise performance, alter gastric blood flow and mediate glucose uptake in healthy individuals. Aim: Does dietary nitrate reduce the O2 co…
Membrane proteins play an integral role in the control of ion transport across the cell membrane in biological systems. However, due to experimental constraints, structural and functional data available for these proteins is limited, especially considering their importance. In t…
The presented research includes analysis and interpretation of the upper 50 m of a deep ice core which was drilled at 49°48'22"N, 86°33'52" (4115 m.a.s.l.) on the Belukha Plateau, Altai, in southwestern Siberia. The main goal was to examine variability of geochemical records pre…
Increased atmospheric deposition of nitrate and ammonium is a consequence of the anthropogenic creation of reactive nitrogen. The impacts of elevated nitrogen deposition to Earth's temperate forests are of particular interest due to their economic importance and the disproportio…
A number of methods are currently in use for attenuating nitrates from wastewater with varying degrees of efficiency. Bioremediation using bacteria may be an efficient and cost effective method. In an anaerobic bioremediation system, nitrate can replace carbon dioxide as an elec…
