Dark matter results from 225 live days of XENON100 data

2012

We report on a search for particle dark matter with the XENON100 experiment, operated at the Laboratori Nazionali del Gran Sasso (LNGS) for 13 months during 2011 and 2012. XENON100 features an ultra-low electromagnetic background of (5.3 \pm 0.6) \times 10^-3 events (kg day keVee)^-1 in the energy region of interest. A blind analysis of 224.6 live days \times 34 kg exposure has yielded no evidence for dark matter interactions. The two candidate events observed in the pre-defined nuclear recoil energy range of 6.6-30.5 keVnr are consistent with the background expectation of (1.0 \pm 0.2) events. A Profile Likelihood analysis using a 6.6-43.3 keVnr energy range sets the most stringent limit o…

Cost Reduction in Irrigation Networks by an Efficient Use of Pressure Reducing Valves

1992

The cost effective design of hydraulic networks has been traditionally studied from the point of view of the relationship between hydraulic variables and economic parameters, with piping being the main element studied. The reason is clear: the piping is by far the most costly item of a projected network. However it is not usual to find an explicit consideration of the influence that pipe thickness has on the cost of the network because of the added difficulty that this aspect poses to formulating the problem of optimization. In irrigation networks, which are typically branched, it is advisable to place Pressure Reducing Valves (PRV’s) to fulfil three main goals: 1) to control the flow rate …

One-Counter Verifiers for Decidable Languages

2013

Condon and Lipton (FOCS 1989) showed that the class of languages having a space-bounded interactive proof system (IPS) is a proper subset of decidable languages, where the verifier is a probabilistic Turing machine. In this paper, we show that if we use architecturally restricted verifiers instead of restricting the working memory, i.e. replacing the working tape(s) with a single counter, we can define some IPS’s for each decidable language. Such verifiers are called two-way probabilistic one-counter automata (2pca’s). Then, we show that by adding a fixed-size quantum memory to a 2pca, called a two-way one-counter automaton with quantum and classical states (2qcca), the protocol can be spac…

Planktonic foraminifera in ODP Hole 160-963A

2006

New faunal and floral records from Ocean Drilling Project Hole 963A, resolved at ?80-year spacing, provide evidence of suborbital scale climate variability in the central Mediterranean Sea throughout Marine Isotope Stage (MIS) 5. Cold events in the central Mediterranean Sea, indicated by low abundances of warm species and high abundances of cold species, are also evident in a planktonic foraminifera paleoclimatic curve. They have been linked to NGRIP Greenland ice core “C” events and appear correlative with similar sub-millennial climate fluctuations identified in the North Atlantic region and in the Alboran Basin (Westernmost Mediterranean). Low-resolution benthic and planktonic Oxygen Iso…

The development of reflective learning in the context of health counselling and health promotion during nurse education.

2001

The development of reflective learning in the context of health counselling and health promotion during nurse education Aims and background. The purpose of this follow-up study was to describe the development of reflective learning of 16 student nurses in the context of health counselling and promotion during clinical training of a 3-year nursing education programme in two Finnish polytechnics. The first aim was to analyse the levels of reflectivity in the student nurses’ reflections on their videotaped counselling situations. The second aim was to explore the qualitative features of the reflective health counselling learning process in the context of health promotion. The theoretical backg…

Mining minerals and critical raw materials from bittern: Understanding metal ions fate in saltwork ponds

2022

Seawater represents a potential resource for raw materials extraction. Although NaCl is the most representative mineral extracted other valuable compounds such as Mg, Li, Sr, Rb and B and elements at trace level (Cs, Co, In, Sc, Ga and Ge) are also contained in this “liquid mine”. Most of them are considered as Critical Raw Materials by the European Union. Solar saltworks, providing concentration factors of up-to 20 to 40, offer a perfect platform for the development of minerals and metal recovery schemes taking benefit of the concentration and purification achieved along the evaporation saltwork ponds. However, the geochemistry of these elements in this environment has not been yet thoroug…

Ab initiocalculations of theHcenters in MgF2crystals

2012

MgF2 with rutile structure is important wide-gap optical material with numerous applications. We present and discuss the results of calculations for basic hole defects - interstitial F atoms (called also the colour H centres). This study is based on the large scale ab initio DFT calculations using hybrid B3PW exchange-correlation functional as implemented into CRYSTAL computer code. The electronic structure, atomic geometry, charge density distribution are calculated and discussed.

Producción de personas, reproducción de representaciones. Reflexiones sobre dos programas de capacitación en liderazgo

2020

The present paper addresses the question of the role Executive Education performs in the strengthening and reproduction of neoliberal ideology. It aims to critically reflect on the way selected contents and teaching activities operate jointly enabling or inhibiting certain perspectives regarding work in organizations. Two Leadership training programs are analyzed in this article, currently delivered by the two most prestigious business schools in Argentina: IAE Business School, and Torcuato Di Tella Business School. I begin with a general description of each one and proceed analyzing their educational proposals. Finally, the critical review reveals their consistency with a set of social rep…
