Understanding shallow water lakes is important because they are not only subjected to a number of natural and anthropogenic stressors but are also able to switch from clear states with high levels of biodiversity to dominance ...

The potential benefits of selection for efficient lean meat growth under restricted feeding have been indicated by selection experiments by McPhee et al. (1988) and Cameron and Curran (1995). The earlier selection experiment by McPhee et al. (1988) showed that scale feeding better exposed the genetic variation in partitioning of food into lean and fat deposition indicating that it might be the ...

in this work a rapid and selective procedure for separation and preconcentration of lead(pb2+) before determination by electrothermal atomic absorption spectrometry (etaas) wasdeveloped. the procedure is based on the electrodeposition on a graphite probe modified withpalladium. the lead was deposited from acetate buffer solution at ph 5.5. various parameters,such as ph of solutions, deposition ...

We recently introduced a method that allows the controlled deposition of nanoscale metallic patterns at defined locations using the tip of an atomic force microscope (AFM) as a "mechano-electrochemical pen", locally activating a passivated substrate surface for site-selective electrochemical deposition. Here, we demonstrate the reversibility of this process and study the long-term stability of ...

We investigated the morphological and structural change in silicon nanostructures embedded in the silicon oxynitride matrix. The study has been carried out on thin films thermally annealed at high temperature, after deposition at 400°C by Electron Cyclotron Resonance Plasma Enhanced Chemical Vapour Deposition (ECR‐ PECVD), under different deposition parameters. Our stud...

Conventional throughfall collection methods are labor intensive and analytically expensive to implement at broad scales. This study was conducted to test an alternative approach requiring infrequent sample collection and a greatly reduced number of chemical analyses. The major objective of the study was to determine the feasibility of using ion exchange resin (IER) to measure N deposition in th...
