Abstract: Hitherto unobserved long-lived massive particles with electric and/or colour charge are predicted by a range of theories which extend the Standard Model. In this Letter a search is performed at the ATLAS experiment for slow-moving charged particles produced in proton–proton collisions at 7 TeV centre-of-mass energy at the LHC, using a data-set corresponding to an integrated luminosity of 34 pb−1. No deviations from Standard Model expectations are found. This result is interpreted in a framework of supersymmetry models in which coloured sparticles can hadronise into long-lived bound hadronic states, termed R-hadrons, and 95% CL limits are set on the production cross-sections of squarks and gluinos. The influence of R-hadron interactions in matter was studied using a number of different models, and lower mass limits for stable sbottoms and stops are found to be 294 and 309 GeV respectively. The lower mass limit for a stable gluino lies in the range from 562 to 586 GeV depending on the model assumed. Each of these constraints is the most stringent to date. [Copyright &y& Elsevier]

The requests for hospital-at-home palliative care are made by health professionals as well as by patients and their families. Nurse coordinators assess them in order to identify the limits and assure high-quality care. Team meetings enable professionals to decide on a joint approach and provide support to the caregivers where necessary., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

The risk/benefit ratio weighs up on the one hand the expected advantages and on the other the potential risks of a procedure. It is taken into consideration with every therapeutic decision, whether it concerns medication-based treatments, psychotherapy or any other type of treatment. The ethical dimension is a critical element which must be taken into account during team deliberations, whenever these are possible., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)
