The River Lea 1571-1767: a river navigation prior to canalisation
No full textPhDIn pre-industrial England river navigations were subject
to improvement by canalisation, the introduction of
artificial navigation cuts and pound locks. Along the Lea
this did not happen until 1767. Before that the navigation,
except for one short period, relied upon a less efficient
technology, the provision of flashes from fishing weirs,
turnpikes and mills. Yet the river was still an important
transport route, particularly for the supply of grain, meal
and malt to London. It had been this during the mediaeval
period, but not by the middle of the sixteenth century. Then
in 1571 the City of London sponsored legislation to construct
a canal from the Lea to London. Parliamentary opposition
thwarted the original ambitious scheme, so two cheaper,
shorter canals were considered, but never built. Instead
an ambitious and unique river improvement scheme was
successfully implemented. This experimental navigation
(reducing reliance on flashes to a minimum) survived 20
years, before persistent and violent opposition from land
carriers closed it. A Star Chamber case upheld the rights
of the bargemen, but the experimental navigation was not
restored. Instead the traditional flash-lock navigation
re-appeared, and was to last, with only minor improvementg
until 1767. In the intervening years the navigation
continued to expand and prosper., This despite the admitted
problems of relying on flashes and tides, and despite a
series of major disputes with the New River Companyq the
millers, fishermen and riparian land-owners. Conflict there
certainly was, but also compromise. Ultimately all parties
were prepared to accept the conflicting rights of other
users, provided they could defend their own. commissions
of Sewers provided an effective administrative forum to
effect and authorise such compromise, even after the
appointment of a body of Trustees in 1739. That the Lea
was an adequate navigation before canalisation, despite
a 'second-best' technology and an unpaid part-time administrative
structure means' that a valid comparison with the
concept of Appropiate Technology, discussed in modern-day
development theory, is possible
Characterization of two, desiccation linked, Group 1 LEA proteins from the resurrection plant Xerophyta humilis
No full textStudies on resurrection plants and other anhydrobiotic organisms show expression of Late Embryogenesis Abundant (LEA) proteins associated with desiccation tolerance. However, the precise role of these proteins has not been described. This study was undertaken to investigate expression, structure and function of XhLEA1-4S1 and XhLEA1-1S2, Group 1 LEA proteins from Xerophyta humilis, in order to shed light on their role in desiccation tolerance. Complementary DNA (cDNA) of these XhLEAs were cloned into bacterial expression vectors and the recombinant proteins expressed in E. coli. Antibodies were generated and used in determination of expression conditions and immunolocalization studies

Nuclear modification of light flavour and strangeness at LHC energies with ALICE
No full textThanks to its unique particle identification capabilities the ALICE detector is able to identify light-flavour, strange and multi-strange hadrons, including π, K, p, , Λ, Ξ and Ω, over a wide range of transverse momentum, from pp and p–Pb interactions up to central Pb–Pb collisions. The latest results on the nuclear modification factor, R (AA), as a function of the Pb–Pb collision centrality, is shown for various particle specie at centre-of-mass energy. For each particle specie, the R (AA) is compared with the nuclear modification factors R (pA) in p-Pb collisions to asses the presence of hot nuclear matter effects affecting the high-p (Τ) particle production in Pb–Pb collisions. The results on the R (AA) of charged hadrons at , the highest energy ever reached in the laboratory for heavy-ion collisions, is also shown
ER5, a tomato cDNA encoding an ethylene-responsive LEA-like protein: characterization and expression in response to drought, ABA and wounding
No full textWe report the isolation by differential display of a novel tomato ethylene-responsive cDNA, designated ER5. RT-PCR analysis of ER5 expression revealed an early (15 min) and transient induction by ethylene in tomato fruit, leaves and roots. ER5 mRNA accumulated during 2 h of ethylene treatment and thereafter underwent a dramatic decline leading to undetectable expression after 5 h of treatment. The full-length cDNA clone of 748 bp was obtained and DNA sequence analysis showed strong homologies to members of the atypical hydrophobic group of the LEA protein family. The predicted amino acid sequence shows 67%, 64%, 64%, and 61%sequence identity with the tomato Lemmi9, soybean D95-4, cotton Lea14-A, and resurrection plant pcC27-45 gene products, respectively. As with the other members of this group, ER5 encodes a predominantly hydrophobic protein. Prolonged drought stress stimulates ER5 expression in leaves and roots, while ABA induction of this ethylene-responsive clone is confined to the leaves. The use of 1-MCP, an inhibitor of ethylene action, indicates that the drought induction of ER5 is ethylene-mediated in tomato roots. Finally, wounding stimulates ER5 mRNA accumulation in leaves and roots. Among the Lea gene family this novel clone is the first to display an ethylene-regulated expression
(Anti-)deuteron production and anisotropic flow measured with ALICE at the LHC
No full textThe high abundance of (anti-)deuterons in the statistics gathered in Run 1 of the LHC and the excellent performance of the ALICE setup allow for the simultaneous measurement of the elliptic flow and the deuteron production rates with a large transverse momentum () reach. The (anti-) deuterons are identified using the specific energy loss in the time projection chamber and the velocity information in the time-of-flight detector. The elliptic flow of (anti-)deuterons can provide insight into the production mechanisms of particles in heavy-ion collisions. Quark coalescence is one of the approaches to describe the elliptic flow of hadrons, while the production of light nuclei can be also depicted as a coalescence of nucleons. In these proceedings, the measured of deuterons produced in Pb--Pb collisions at =2.76TeV will be compared to expectations from coalescence and hydrodynamic models.The high abundance of (anti-)deuterons in the statistics gathered in Run 1 of the LHC and the excellent performance of the ALICE setup allow for the simultaneous measurement of the elliptic flow and the deuteron production rates with a large transverse momentum ( p T ) reach.
