background : falls are important causes of mortality and morbidity in urban areas and put a high burden on societies. we investigated patterns of fall traumas and related factors in a referral trauma hospital in tehran, iran. methods: in this routine-data-based study, all documents of fall cases in hazrate-rasool hospital, tehran, iran, during october 2014-2015 were investigated. information on...
We investigate decaying D-branes as the origin of the thermal string gas of string gas cosmology. We consider initial configurations of low-dimensional branes and argue that they can time evolve to thermal string gas. We find that there is a range in the weak string coupling and fast brane decay time regimes, where the initial configuration could drive the evolution of the dilaton to values, wh...
Consider a globally hyperbolic cosmological spacetime. Topologically, the spacetime is then a compact 3-manifold in cartesian product with an interval. Assuming that there is an expanding direction, is there any relation between the topology of the 3-manifold and the asymptotics? In fact, there is a result by Michael Anderson, where he obtains relations between the long-time evolution in Genera...
BACKGROUND The aim of this study was to survey minor home help services provided by Swedish municipalities with the main purpose to prevent fall injuries. METHODS If minor home help services were presented on the homepage of a municipality, an initial telephone contact was taken. Thereafter a questionnaire was administered, including questions about target groups, aim with the services, tasks...
در این پروژه به مطالعه رفتار غیرمنتظره سطح مقطع های همجوشی در انرژی های پایین تر از سد کولنی پرداخته ایم. برای این منظور از واکنش همجوشی یون های سنگین، که در آن ها مقدارq منفی می باشد، استفاده کرده ایم. به طورکلی منظور از رفتار غیرمنتظره، کاهش ناگهانی مقادیرسطح مقطع آزمایشگاهی steep fall offنسبت به مدل های تئوری نظیر آکیوز- وینتر می باشد که دلیل آن را می توان ناشی از یک عامل بازدارنده همجوشی (f...
The reaction 28 Si + 181 Ta has been studied at E Lab =125 and 135 MeV. Coincidences between high energy particles and various X-and γ-rays from abnormally long-lived states were observed. e.g. 7.8-8.6 MeV α-particles with γ-rays of a superdeformed band, 5.1-5.5 MeV α-particles with X-and γ-rays of W, Re, and Pt, and 3.88 MeV particles (interpreted as protons) with 185.8 keV γ-rays. The data ar...
Artificial reverberation is an important music production tool with a strong but poorly understood perceptual impact. A literature review of the relevant works concerned with the perception of musical reverberation is provided, and the use of artificial reverberation in multisource mixes is studied. The perceived amount of total artificial reverberation in a mixture is predicted using relative ...
The semileptonic CP asymmetry in B-B̄ mixing, asl, is measured in proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb−1, recorded by the LHCb experiment. Semileptonic B decays are reconstructed in the inclusive final states D−μþ and D −μþ, where the D− meson decays into theKþπ−π− final state and theD − meson into the D̄0ð→ Kþπ−Þπ− final state. The asymmetry between t...
