Abstract Arising out of the challenge for Local Authorities (LAs) to operate sustainable systems work, is avoid creation ill-health including most significant causes physical absence, musculoskeletal disorders (MSDs). The study's aim was compare reliability manual handling element Health and Safety Executives (HSEs) risk comparator tool different domestic waste collection methods with self-repo...
Assume V = L. Let k be a regular cardinal and for X Qk let a(X) denote the least ordinal a such that ¿„[A"] is admissible. In this paper we characterize those ordinals of the form <x{X) using forcing and fine structure of L techniques. This generalizes a theorem of Sacks which deals with the case k = w. Forcing has proved to be an extremely valuable tool for the recursion-theorist. Generic sets...
Under Martin’s axiom, collapsing of the continuum by Sacks forcing S is characterized by the additivity of Marczewski’s ideal (see [4]). We show that the same characterization holds true if d = c proving that under this hypothesis there are no small uncountable maximal antichains in S. We also construct a partition of 2 into c perfect sets which is a maximal antichain in S and show that s-sets ...
Libman-Sacks endocarditis (LSE) is a common manifestation of valve disease in antiphospholipid syndrome. Mitral valve LSE is characterized by verrucous vegetations on the atrial surfaces of valve leaflets. In this report, mitral valve LSE was visualized by real time 3D transesophageal echocardiography (TEE). 3D TEE provides a unique en face view of the mitral valve akin to a surgical or autopsy...
We will present a collection of guessing principles which have a similar relationship to ♦ as cardinal invariants of the continuum have to CH. The purpose is to provide a means for systematically analyzing ♦ and its consequences. It also provides for a unified approach for understanding the status of a number of consequences of CH and ♦ in models such as those of Laver, Miller, and Sacks.
