Regulation of supply for Cheese with a protected designation of origin or protected geographical indication
No full textSince 2007, the agri-food market has registered high price volatility, which has led to significant problems, particularly for farmers. At the same time, the European Union is completing the dismantling of the old market policy, which is based on the direct tools of agricultural policy (e.g., quotas and guaranteed prices), and is increasing the adoption of indirect tools1, which do not act directly on the market but on the actors of the market. One of these tools, which is the latest to be adopted, is the regulation of supply with a protected designation of origin and a protected geographical indication (DOP and IGP), which was introduced in 2012 with the approval of the “Milk package”. This article, following an introductory overview, focuses on an assessment of the effect of the regulation of the supply of cheese with a protected designation of origin or a protected geographical indication through the case study of a Grana Padano Dop dairy farm. This is a preliminary work without extendable research results but is useful to understand the potentiality of this new tool of agricultural policy
La diversificazione delle attività agricole
No full textIl capitolo è dedicato alla descrizione della situazione e delle condizioni strutturali delle aziende agricole umbre che hanno adottato percorsi di diversificazione.
In particolare, dopo aver descritto il concetto di diversificazione, si analizzeranno le attività remunerative connesse all’azienda agricola, l’importanza del contoterzismo, la presenza di impianti per la produzione di energia nelle aziende, l’entità delle superfici soggette a contratto di coltivazione per la realizzazione di coltivazioni energetiche e, infine, la presenza di ricavi dalle attività diversificate
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Search for direct scalar top pair production in final states with two tau leptons in pp collisions at sqrt(s) = 8 TeV with the ATLAS detector
No full textA search for direct pair production of the supersymmetric partner of the top quark, decaying via a scalar tau to a nearly massless gravitino, has been performed using 20 fb−1 of proton-proton collision data at sqrt(s) = 8 TeV. The data were collected by the ATLAS experiment at the LHC in 2012. Scalar top candidates are searched for in events with either two hadronically decaying tau leptons, one hadronically decaying tau and one light lepton, or two light leptons. No significant excess over the Standard Model expectation is found. Exclusion limits at 95% confidence level are set as a function of the scalar top and scalar tau masses. Depending on the scalar tau mass, ranging from the 87 GeV LEP limit to the scalar top mass, lower limits between 490 GeV and 650 GeV are placed on the scalar top mass within the model considered
Searches for scalar leptoquarks in pp collisions at sqrt(s) = 8 TeV with the ATLAS detector
No full textSearches for pair-produced scalar leptoquarks are performed using 20 fb-1 of proton-proton collision data provided by the LHC and recorded by the ATLAS detector at sqrt(s) = 8 TeV. Events with two electrons (muons) and two or more jets in the final state are used to search for first (second)-generation leptoquarks. The results from two previously published ATLAS analyses are interpreted in terms of third-generation leptoquarks decaying to b?tb ̄?t ̄ and t?tt ̄?t ̄ final states. No statistically significant excess above the Standard Model expectation is observed in any channel and scalar leptoquarks are excluded at 95% CL with masses up to mLQ1 < 1050 GeV for first-generation leptoquarks, mLQ2 < 1000 GeV for second-generation leptoquarks, mLQ3< 625 GeV for third-generation leptoquarks in the b?tb ̄?t ̄ channel, and 200 <mLQ3< 640 GeV in the t?tt ̄?t ̄ channel
Search for heavy long-lived charged R-hadrons with the ATLAS detector in 3.2 fb−1 of proton-proton collision data at sqrt(s) = 13 TeV
Full text linkA search for heavy long-lived charged R-hadrons is reported using a data sample corresponding to 3.2−1 of proton--proton collisions at sqrt(s) = 13 TeV collected by the ATLAS experiment at the Large Hadron Collider at CERN. The search is based on observables related to large ionisation losses and slow propagation velocities, which are signatures of heavy charged particles travelling significantly slower than the speed of light. No significant deviations from the expected background are observed. Upper limits at 95% confidence level are provided on the production cross section of long-lived R-hadrons in the mass range from 600 GeV to 2000 GeV and gluino, bottom and top squark masses are excluded up to 1580 GeV, 805 GeV and 890 GeV, respectively
Z boson production in p+Pb collisions at sqrt(s_NN)=5.02 TeV measured with the ATLAS detector
No full textThe ATLAS Collaboration has measured the inclusive production of Z bosons via their decays into electron and muon pairs in p+Pb collisions at sqrt(sNN)=5.02 TeV at the Large Hadron Collider. The measurements are made using data corresponding to integrated luminosities of 29.4 nb-1 and 28.1 nb-1 for Z?ee and Z?μμ, respectively. The results from the two channels are consistent and combined to obtain a cross section times the Z?ll branching ratio, integrated over the rapidity region |y*Z|<3.5, of 139.8 ± 4.8 (stat.) ± 6.2 (syst.) ± 3.8 (lumi.) nb. Differential cross sections are presented as functions of the Z boson rapidity and transverse momentum, and compared with models based on parton distributions both with and without nuclear corrections. The centrality dependence of Z boson production in p+Pb collisions is measured and analyzed within the framework of a standard Glauber model and the model's extension for fluctuations of the underlying nucleon-nucleon scattering cross section
Charged-particle distributions at low transverse momentum in sqrt(s) = 13 TeV pp interactions measured with the ATLAS detector at the LHC
Full text linkMeasurements of distributions of charged particles produced in proton-proton collisions with a centre-of-mass energy of 13 TeV are presented. The particles are required to have a transverse momentum greater than 100 MeV and an absolute pseudorapidity less than 2.5. The charged-particle multiplicity, its dependence on transverse momentum and pseudorapidity and the dependence of the mean transverse momentum on multiplicity are measured in events containing at least two charged particles satisfying the above kinematic criteria. The data were recorded by the ATLAS detector at the LHC and correspond to an integrated luminosity of 170 μb−1. The results are corrected for detector effects and compared to the predictions from several Monte Carlo event generators
