Many people who live in the low altitude areas are often suffered from hypoxia when they entered the high plateau. This problem may seriously influence the physical and mental state and work efficacy for the travelers and workers. Oxygen enrichment of a small space air at high altitude is considered as a simple way to provide lowlanders enriched oxygen for sleeping and resting, improving work e...
0 Ts|Bt| dt t ) 1 2 ||L∞(Ω). for any family (At)t≥0 ∈ L(Ω, μ), (Bt)t≥0 ∈ L∞(Ω, μ) provided (Tt)t≥0 does not increase or decrease “too fast”. As an application, we prove a duality inequality for H − BMO spaces associated with general subordinated Poisson semigroups. All the results are proved in a more general setting, that is for (Bt)t≥0 and (At)t≥0 being families of elements of a semifinte von...
We study tent spaces on general measure spaces (Ω, μ). We assume that there exists a semigroup of positive operators on Lp(Ω, μ) satisfying a monotone property but do not assume any geometric/metric structure on Ω. The semigroup plays the same role as integrals on cones and cubes in Euclidean spaces. We then study BMO spaces on general measure spaces and get an analogue of Fefferman’s H1-BMO du...
Background. On October 17, 2007, a severe weather event collapsed two large tents and several smaller tents causing 23 injuries requiring evacuation to emergency departments in Tulsa, OK. Methods. This paper is a retrospective analysis of the regional health system's response to this event. Data from the Tulsa Fire Department, The Emergency Medical Services Authority (EMSA), receiving hospitals...
