Characterization of two, desiccation linked, Group 1 LEA proteins from the resurrection plant Xerophyta humilis
Studies 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
Thanks 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
The River Lea 1571-1767: a river navigation prior to canalisation
PhDIn 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

(Multi-)strange hadron and light (anti-)nuclei production with ALICE at the LHC
Thanks to its excellent tracking performance and particle identification capabilities, the ALICE detector allows for the identification of light (anti-)(hyper)nuclei and for the measurement of (multi-)strange particles over a wide range of transverse momentum. Deuterons, 3He and 4He and their corresponding anti-nuclei are identified via their specific energy loss in the Time Projection Chamber and the velocity measurement provided by the Time-Of-Flightdetector. Strange and multi-strange baryons and mesons as well as (anti-)hypertritons are reconstructed via their topological decays.Detailed measurements of (multi-)strange hadron production in pp, p–Pb and Pb–Pb collision and of light (anti-)nuclei and (anti-)hypertritons in Pb–Pb collisions with ALICE at the LHC are presented.The experimental results will be compared with the predictions of both statistical hadronization and coalescence models
(Anti-)deuteron production and anisotropic flow measured with ALICE at the LHC
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 () 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.
