Studies using roentgen stereophotogrammetric analysis (RSA) have shown that the femoral components of cemented total hip replacements (THR) migrate distally relative to the bone, but it is not clear whether this occurs at the cement-implant or the cement-bone interface or within the cement mantle. Our aim was to determine where this migration occurred, since this has important implications for ...

The referential analysis of conditionals has recently been put forth as an alternative the Kratzer-style restrictor (Schein 2001, Schlenker 2004, among others). Under this analysis, conditional antecedents are definite descriptions worlds/situations. This paper explores a widely accepted assumption namely that refer to plural objects. I show singularity/plurality can correlate with whether expr...

En este trabajo se defiende una postura intermedia acerca de la racio-nalidad en toma decisiones un juez constitucional, ello, a través del desarrollo modelo teórico denominado tesis restrictor cognitivo, el cual caracteriza por serie parámetros objetivos que constriñen y orientan cognitivamente proceso decisión sede con finalidad establecer racionalidad procedi-mental reduzca los espacios subj...

Cement restriction and pressurisation are helpful technical points in achieving a good cement mantle in cemented hip replacement. In this prospective study, we compared 39 cases where a Hardinge polyethylene restrictor was used and 33 cases where a bone block restrictor was used during Charnley hip replacement. The preoperative radiographs were templated, calibrated holders for the cement restr...

Identification of the specific HLA locus and allele presenting an epitope for recognition by specific TCRs (HLA restriction) is necessary to fully characterize the immune response to Ags. Experimental determination of HLA restriction is complex and technically challenging. As an alternative, the restricting HLA locus and allele can be inferred by genetic association, using response data in an H...

Downward entailing linguistic environments license inferences from sets to their subsets. These environments also determine the interpretation of disjunction: Disjunction licenses a conjunctive entailment in the scope of downward entailing operators (Crain 2008, 2012). This leads to a striking asymmetry across languages in the interpretation of disjunction when it appears in the restrictor (dow...

Elbow arthroplasty is performed less often than hip or knee arthroplasty. The most common reason for patients requiring elbow arthroplasty is chronic inflammatory joint disease, usually rheumatoid arthritis.1 Two main types of prostheses exist, linked and nonlinked. Prosthesis fixation in bone is achieved with bone cement in almost all linked and non-linked prostheses.2 Cement restrictors preve...
