Berry's phase in noncommutative spaces
We introduce the perturbative aspects of noncommutative quantum mechanics.
Then we study the Berry's phase in the framework of noncommutative quantum
mechanics. The results show deviations from the usual quantum mechanics which
depend on the parameter of space/space noncommtativity.Comment: 7 pages, no figur
Dependency in Activities of Daily Living Following Limb Trauma in Elderly Referred to Shahid Beheshti Hospital, Kashan-Iran in 2013
Background: Activities of daily living (ADL) are an important indicator of health and independence in elderly. It provides useful information for proper planning in the field of elderly care. Trauma in elderly population is frequent and can negatively affect the independence in ADL.
Objectives: The purpose of the present study was to evaluate elderly independence in activities of daily living (ADL) following limb trauma and its related factors in patients referred to trauma emergency ward of Shahid Beheshti Hospital, Kashan, Iran, in 2013.
Patients and Methods: This descriptive study was conducted on 200 traumatic patients admitted to trauma emergency ward of Shahid Beheshti Hospital in 2013. The questionnaire used in this study had three parts as demographic data, information related to trauma and ISADL (independency scale of activities of daily living). ISADL was completed in emergency ward to declare pretraumatic status; it was also completed 1 and 3 months after trauma. Statistical analysis was conducted by Chi-square test, One-way and two-factor ANOVA, and Multiple regression analysis. Data analysis was conducted using SPSS software, version 16.
Results: The average age of participants was 70.57 ± 9.05 years. In total, 80.5% of the elderly were completely independent in ISADL before trauma; this decreased to 13.5% one month after trauma. Besides, 32% of the elderly were completely or relatively dependent three months after trauma. Two-factor ANOVA showed a significant association between the scores of ISADL, the time interval and the type and location of an injured organ, and having the surgery as a treatment.
Conclusions: More than three-quarters of the elderly were independent in ISADL before the trauma, but trauma in elderly patients had a substantial negative effect on patients' ability and ADL function
Bound of Noncommutativity Parameter Based on Black Hole Entropy
We study the bound of the noncommutativity parameter in the noncommutative
Schwarzschild black hole which is a solution of the noncommutative ISO(3,1)
Poincare gauge group. The statistical entropy satisfying the area law in the
brick wall method yields a cutoff relation which depends on the
noncommutativity parameter. Requiring both the cutoff parameter and the
noncommutativity parameter to be real, the noncommutativity parameter can be
shown to be bounded as .Comment: LaTeX 7 pages, references added, minor correction
