Below the Salt Marsh Surface: Visualization of Plant Roots by Computer-Aided Tomography
Computer-Aided Tomography Salt Marsh Surface
font style='font-size:12px;'>
2015/7/16
As sea level rises, salt marshes become subtidal mudflats unless soil surface accretion occurs at rates fast enough to keep the marsh from being submerged (Brinson et al., 1995). The individual proces...

2015/7/14
Let G be a compact separable topological group. When does there exist a
probability P such that P P = U ,where U is Haarmeasure and P + U? We show
that such square roots exist if and only if G is ...
Ethylene negatively regulates aluminium-induced malate efflx from wheat roots and tobacco cells transformed with TaALMT1
Ethylene aluminium tolerance malate efflx ALMT1 wheat (Triticum aestivum L.)
