Low-Intensity Neutron Emission from TiDx Samples Under Nonequilibrium Conditions

2001

Several experiments were performed that loaded titanium samples with deuterium from the gas phase, changed the temperature of the samples over a wide range, and monitored the neutron emission. Neutron emissions in very low intensity bursts, still significantly above the background, were recorded, revealing that low-energy nuclear reactions in condensed matter can be produced at a very low rate, which occasionally can be high enough to become detectable.

Measurement of the low-energy antideuteron inelastic cross section

2020

In this Letter, we report the first measurement of the inelastic cross section for antideuteron-nucleus interactions at low particle momenta, covering a range of $0.3 \leq p < 4$ GeV/$c$. The measurement is carried out using p-Pb collisions at a center-of-mass energy per nucleon-nucleon pair of $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV, recorded with the ALICE detector at the CERN LHC and utilizing the detector material as an absorber for antideuterons and antiprotons. The extracted raw primary antiparticle-to-particle ratios are compared to the results from detailed ALICE simulations based on the GEANT4 toolkit for the propagation of antiparticles through the detector material. The analysis of th…

Exclusive measurement of quasi-free η-photoproduction from deuterium

2003

Quasi-free photoproduction of eta-mesons from the deuteron has been measured at the tagged photon facility of the Mainz microtron MAMI with the photon spectrometer TAPS for incident photon energies from the production threshold at 630 MeV up to 820 MeV. In a fully exclusive measurement eta-mesons and recoil nucleons were detected in coincidence. At incident photon energies above the production threshold on the free nucleon, where final state interaction effects are negligible, an almost constant ratio of sigma(n)/sigma(p)=0.66+/-0.10 was found. At lower incident photon energies the ratio rises due to re-scattering effects. The average ratio agrees with the value extracted from a comparison …

Indijas klimata migrācijas analīze. Feminisma perspektīva

2021

Klimata pārmaiņas turpinās atstāt postošas sekas ne tikai uz ekosistēmām, bet arī cilvēkiem visur pasaulē. Jau šobrīd to ietekmē marginalizētajām grupām globālajos Dienvidos nākas migrēt. Tomēr šo grupu sociālajām identitātēm mijiedarbojoties, veidojas unikālas pieredzes, kā rezultātā attiecības ar migrāciju nevar uzskatīt par viennozīmīgām. Feminisma perspektīva palīdz izprast to attiecības ar migrāciju, veidus, kādos konkrētas sabiedrības grupas piedzīvo klimata pārmaiņas. Intersekcionālais feminisms piedāvā sociālo nevienlīdzību mijiedarbību, varas attiecību analīzi un var palīdzēt turpmāk veidot imigrācijas politiku, kas iekļauj sociālo klimata pārmaiņu aspektu. Darbā veikta Indijas kli…

Incidence and Management of Recurrence in Patients with Crohn's Disease Who Have Undergone Intestinal Resection: The Practicrohn Study.

2017

Background: More than 50% of patients with Crohn's disease require intestinal resection at least once. Postoperative recurrence (POR) is almost uniform if prophylactic treatment is not started early. Endoscopic monitoring is generally advised. We studied the incidence and management of recurrence in patients who had undergone intestinal resection. Methods: Practicrohn was an observational retrospective study performed in 26 Spanish hospitals including patients aged >= 18 years who underwent Crohn's disease-related ileocolonic resection between January 2007 and December 2010. We recorded preventive treatments, the incidence of clinical recurrence in daily practice, and associated risk factor…
