In some spans, however, conductors are connected to the tower by means of special tension equipment which may influence the efficiency of the mounted standard damper.
The paper, combining evidence of driftwood accumulation and beach formation in northern Greenland with evidence of past sea-ice extent in parts of Canada, concludes that Arctic sea ice appears to have retreated far more in some spans since the end of the last ice age than it has in recent years.
To measure the net exchange of C between land ecosystems and the atmosphere (net ecosystem exchange, NEE, with -NEE referred to as net ecosystem productivity, NEP), a global network of over 400 eddy-covariance (EC) flux stations has been established across a range of ecosystems, building an extensive data record of NEP, in some cases spanning up to two decades.
Primers were designed to adjacent constitutively expressed exons, in some cases spanning a few flanking exons.
This surprising finding of expression across the joint region of a gene normally restricted to cells within cartilage rudiments is complimented by detection of COL2A1 transcripts in some cells spanning the interzone in immobilised individuals (n = 7/7), similar to the expression of PTHLP (Figure 6C, D, C' D').
This paper expands this subdominant ultrametric perspective by studying ultrametric networks, consisting of the collection of all edges involved in some minimum spanning tree.
In order to empirically assess the presence or absence of putatively spliced exons, PCR primers were designed on adjacent constitutively expressed exons, in some cases spanning several target exons.
In this paper, we extend the approach based on the construction of subdominant ultrametric trees by studying ultrametric networks, consisting of the collection of all edges involved in some minimum spanning tree.
DOI: http://dx.doi.org/10.7554/eLife.03700.007 The SeqZip design requires efficient ligation of multiple DNA oligos (ligamers), some spanning loops in the RNA template.
Robotic missions to Mars shall meet planetary protection specifications, currently well documented, and planetary protection programs are implemented in a very reliable manner given that experience in the field spans some 40 years.
