Iowa's Living Roadway Plant Profiler, August 21, 2003 [PDF]

open access: yes, 2003
This publication is a guide to understanding the Iowa Department of Transportation’s roadside management programs. It offers descriptions of various landscape designs or planting styles used within or adjacent to Iowa’s highway rights-of-way, as well ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

SERS of plant material [PDF]

open access: yesJournal of Raman Spectroscopy, 2007
AbstractColloidal gold and silver were formed by the spontaneous reduction of metal salts by plant tissue—alfalfa seeds, green tea leaves, carrots and red cabbage. The colloids were analyzed using electron microscopy and spectroscopic tools. The reduction process yielded stable gold colloids, but for silver the colloidal particles were bigger and less ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

New concepts of plant nutrition in production of the planting material: Hazelnut planting material production [PDF]

open access: yes, 2006
U radu su predstavljeni rezultati ogleda u kome su ispitivani efekti primene novih vrsta đubriva i načina đubrenja u proizvodnji sadnog materijala leske. Ogled je postavljen na gajnjači đubrenoj pri meliorativnom đubrenju sa 100 t/ha stajnjaka. Kontrolna varijanta je bez primene mineralnih đubriva, dok je NPK (15:15:15) varijanta sa 600 kg/ha tretirana

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Use efficiency of nitrogen from biodigested plant material by ryegrass

open access: yes, 2010
Apparent nitrogen-use efficiency of the applied mineral N (NUE(min)) in effluent from biodigested plant material (BE; C : N(org) ratio 14:1; mineral N-to-total N ratio 0.5:1) and a nitrate-based inorganic fertilizer (IF), both applied at two rates was ...
