Special tool kit aids heavily garmented workers

Triangular aluminum tool kit, filled with polyurethane is constructed to receive various tools and hold them in a snug but quick-release fit as an aid to heavily gloved workers. The kit is designed to allow mounting within easily accessable reach and to provide protection of the tools during storage

Psychiatric illness predicts poor outcome after surgery for hip fracture: a prospective cohort study

Background. Hip fracture is common in the elderly. Previous studies suggest that psychiatric illness is common and predicts poor outcome, but have methodological weaknesses. Further studies are required to address this important issue. Methods. We prospectively recruited 731 elderly participants with hip fracture in two Leeds hospitals. Psychiatric diagnosis was made within 5 days of surgery using the Geriatric Mental State schedule and other standardized instruments, and data on confounding factors was collected. Main study outcomes were length of hospital stay, and mortality over 6 months after fracture. Results. Fifty-five per cent of participants had cognitive impairment (dementia in 40% and delirium in 15%), 13% had a depressive disorder, 2% had alcohol misuse and 2% had other psychiatric diagnoses. Participants were likely to remain in hospital longer if they suffered from dementia, delirium or depression. The relative risks of mortality over 6 months after hip fracture were increased in dementia and delirium, but not in depression. Conclusions. Psychiatric illness is common after hip fracture, and has significant effects on important outcomes. This suggests a need for randomized, controlled trials of psychiatric interventions in the elderly hip fracture population

Concepts for the development of light-weight composite structures for rotor burst containment

A set of hypotheses is established as to what variables might control the design of a weight-efficient protective device. A particular experiment for evaluating the hypotheses and materials was designed. The design and methods for the analysis of results are described

Isospin quantum number of D_{s0}^+(2317)

The D_s^+ pi^0 and D_s^{*+} gamma decays of the D_{s0}^+(2317) are studied by assigning it to various charmed strange scalar mesons. As a result, it is found that its assignment to an iso-triplet four-quark meson is favored by the severest experimental constraint on the ratio of the rates for these decays, while assigning it to an I=0 state (a four-quark or a conventional {c\bar{s}}) is inconsistent with this constraint.Comment: 6 pages, no figure, RevTeX4, references added and clarification of tex

Attention modulates the processing of emotional expression triggered by foveal faces

To investigate whether the processing of emotional expression for faces presented within foveal vision is modulated by spatial attention, event-related potentials (ERPs) were recorded in response to stimulus arrays containing one fearful or neutral face at fixation, which was flanked by a pair of peripheral bilateral lines. When attention was focused on the central face, an enhanced positivity was elicited by fearful as compared to neutral faces. This effect started at 160 ms post-stimulus, and remained present for the remainder of the 700 ms analysis interval. When attention was directed away from the face towards the line pair, the initial phase of this emotional positivity remained present, but emotional expression effects beyond 220 ms post-stimulus were completely eliminated. These results demonstrate that when faces are presented foveally, the initial rapid stage of emotional expression processing is unaffected by attention. In contrast, attentional task instructions are effective in inhibiting later, more controlled stages of expression analysis
