The use of high throughput molecular methods that allow for the study of bacterial communities in environmental samples is commonplace in microbial ecology. Until recently, fungal community ecology has
focused on isolation, collection of sporocarps, or collection of ectomycorrhizal roots. The techniques used to extract and amplify DNA from environmental...
Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...
The ability to integrate designs from board level, multi-chip modules to single process solutions is highly attractive in today's PC multimedia industry. Saving board area and chip count will decrease the production cost of personal computing hardware and increase profitability. The ability to integrate analog circuit capability and it's reference...
Nucleic acid estimates in tissues of marine macrophytes with the fluorochromes Hoechst 33258 and ethidium homodimer were severely impaired by high concentrations of interfering compounds. The isolation and extraction techniques used pointed towards compounds of low molecular weight and of polar characteristics that were insensitive to organic solvent extraction and...
Small amounts of carbon from glucose and leucine added at natural
concentrations to seawater were biologically transformed to higher
molecular weight (MW) dissolved materials which persisted through six
months of incubation. These materials were resistant to biological
utilization: only 1 to 17% of the higher MW carbon was respired when...
We developed a model to investigate the dielectric properties of the
BaTiO₃ − Bi(Zn₁/₂Ti₁/₂)O₃ (BT-BZT) solid solution, which is a relaxor ferroelectric and exhibits long range disorder. The model uses ab initio methods
to determine all polarization states for every atomic configuration of 2 x 2 x 2
supercells of...
The use of mobile bar code scanners is expanding to markets beyond popular manufacturing uses, such as healthcare, environmental testing and professional services. The successful interaction of users with mobile bar code scanners is of great importance from a business and technology perspective as well as from the user standpoint....
The market for Wireless Local Area Networks (WLANs) has experienced tremendous growth over the last few years and this trend is expected to continue in the future. This growth is due to the fact that wireless LANs provide several benefits including mobility, efficiency, and accuracy. In addition, the cost of...
