Laser assisted decay spectroscopy at the CRIS beam line at ISOLDE
2012
A new collinear resonant ionization spectroscopy (Cris)beam line has recently been installed at Isolde, Cern utilising lasers to combine collinear laser spectroscopy and resonant ionization spectroscopy. The combined technique offers the ability to purify an ion beam that is heavily contaminated with radioactive isobars, including the ground state of an isotope from its isomer, allowing sensitive secondary experiments to be performed. A new programme aiming to use the Cris technique for the separation of nuclear isomeric states for decay spectroscopy will commence in 2011. A decay spectroscopy station, consisting of a rotating wheel implantation system for alpha decay spectroscopy, and thre…
Invited Article: Ultra-broadband terahertz coherent detection via a silicon nitride-based deep sub-wavelength metallic slit
2018
We present a novel class of CMOS-compatible devices aimed to perform the solid-state-biased coherent detection of ultrashort terahertz pulses, i.e., featuring a gap-free bandwidth at least two decades-wide. Such a structure relies on a 1-µm-wide slit aperture located between two parallel aluminum pads, embedded in a 1-µm-thick layer of silicon nitride, and deposited on a quartz substrate. We show that this device can detect ultra-broadband terahertz pulses by employing unprecedented low optical probe energies of only a few tens of nanojoules. This is due to the more than one order of magnitude higher nonlinear coefficient of silicon nitride with respect to silica, the nonlinear material emp…
A real-time PCR quantitative detection assay for Pseudomonas savastanoi pv. nerii in Nerium oleander
2008
A real-time PCR assay based on TaqMan chemistry was developed for the detection of Pseudomonas savastanoi pathovars that cause bacterial knot disease on different plant species. Primers and probe sequences were based on the iaaL gene coding for (indole-3-acetyl)-L-lysine synthetase and previously used in conventional PCR tests. Assay specificity was tested with an extended range of strains of P. savastanoi from eight hosts, with 13 other Pseudomonas spp., and with other microorganisms naturally occurring on or in oleander plants. A pure culture cell suspension was quantifi ed over a seven log concentration range (108 to 102 cfu ml-1 ). Different protocols were developed for the detection an…
BEST-2K Method for Characterizing Dual-Permeability Unsaturated Soils with Ponded and Tension Infiltrometers
2019
This study presents a new method (BEST-2K) that extends the existing BEST methods for use in characterizing the water retention and hydraulic conductivity functions of matrix and fast-flow regions in dual-permeability soils. BEST-2K requires input information from two water infiltration experiments that are performed under ponded (Beerkan) and unsaturated (tension infiltrometer) conditions at the surface. Other required inputs include water content measurements and the traditional BEST inputs (particle size distribution and bulk density). In this study, first, a flowchart of the BEST-2K method was developed and illustrated with analytically generated data for a synthetic dual-permeability s…
Enhancing a Transition to a Circular Economy in the Water Sector: The EU Project WIDER UPTAKE
2021
A novel approach for resource recovery includes forward osmosis (FO) as a concentration step in municipal wastewater treatment. The current study investigates different pre-treatment strategies including biological treatment with a moving-bed bioreactor (MBBR) at different loading rates and particle removal by filtration and sedimentation. Membrane performance and recovery potential for energy and nutrients were investigated in laboratory-scale FO experiments in batch mode using pre-treated municipal wastewater as feed and 35 g/L NaCl as a draw solution. Initial water fluxes were in the range of 6.3 to 8.0 L/(m2·h). The baseline fluxes were modelled to account for flux decline due to concen…
Con li suoi vestimenti asciugare il morto viso della salata acqua, e bagnarlo di molte lagrime: la "Fiammetta" en el "Leànder y Hero" de Roís de Core…
2005
The «Elegia di madonna Fiammetta» has an evident impact of the story of Leandre and Hero, especially in the moments in which the lady suffers while waiting for her lover, who never comes. Fiammetta makes obvious this parallelism on several occasions, and manages to invent an end for the story loaded of pathos. Joan Roís de Corella realises about this relationship between both two works and makes the inverse path: he uses the tone and some narrative elements of the Elegia for writing his Leander and Hero. It is demonstrated that the so contreversial end of Corella’s story is not original of the Valencian, but it also depends on Boccaccio’s text
Soil Cadastre in Italy for Sustainable Development: the Urban Soil Cadastre (the Second Branch)
2020
The description of the second branch of the Land Cadastre concludes with the description of the structure of the new inventory Land Cadastre. The principles applied are always the same: computer node where all the information present in the various municipal, regional, state, reclamation consortia and research centres can be entered. The scheme used in each branch of the structure is that of the current Cadastre. In this work the guide is the Urban or Buildings with the two elements the Particle Map Sheet and the Cadastral Certificate. The cultural intensification is the first step and concerns both the cartographic part and the areas of the condominiums outside the buildings, and the parti…
Comparative ultrastructure and carbohydrate composition of gastroliths from Astacidae, Cambaridae and Parastacidae freshwater crayfish (Crustacea, De…
2012
21 pages; International audience; Crustaceans have to cyclically replace their rigid exoskeleton in order to grow. Most of them harden this skeleton by a calcification process. Some decapods (land crabs, lobsters and crayfish) elaborate calcium storage structures as a reservoir of calcium ions in their stomach wall, as so-called gastroliths. For a better understanding of the cyclic elaboration of these calcium deposits, we studied the ultrastructure of gastroliths from freshwater crayfish by using a combination of microscopic and physical techniques. Because sugars are also molecules putatively involved in the elaboration process of these biomineralizations, we also determined their carbohy…
Continuous Improvement on Detailed Design Phase : A Process Perspective
2020
The construction project being studied is a government investment related to the relocation of a biomedical institute delivering research-based knowledge and contingency support in the fields of animal health, fish health and food safety. The project covers a total of 63,000 square meters distributed over 10 buildings with a very high degree of complexity. The design alone has required 1 million hours, which relates to a client cost of about 100 million Euro. The purpose of this paper is to study the applied methodology for managing the detailed design to identify lessons learned from the project. The theory underlying the study is inspired by lean design management and design theory linked…
