There are few high quality prognosis studies and none that have measured pain, disability and return to work over a 12 mon...
let r be a commutative ring with non-zero identity and m be a unital r-module. then the concept of quasi-secondary submodules of m is introduced and some results concerning this class of submodules is obtained
The built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. The built up layer (BUL) is formed in second deformation zone near the tool-chip interface in the back of the chip. This parameter influences the tool life and machined surface quality. This BUL should not be confused with the built up edge (BUE). The deformation of the BUL in...
OBJECTIVE The purpose of this study was to quantify rates of back pain among whitewater rafting guides and to look for correlations between the presence of back pain and specific activities associated with guiding. The secondary objective was to provide suggestions for outfitters according to the results of this study, which may be of assistance to their guide staff. METHODS A mail-out-mail-b...

Although most low back pain is nonspecific and self-limiting, a subset of patients develop chronic low back pain, defined as persistent symptoms for longer than three months. Low back pain is categorized as nonspecific low back pain without radiculopathy, low back pain with radicular symptoms...

Limited information in the literature combined with poor awareness across the specialty and among the primary care physicians leads to an extensive investigation and m...
Amprenavir is a protease inhibitor that has been shown to have secondary peaks postulated to be due to enterohepatic recycling. We propose a model to describe the pharmacokinetics of amprenavir which accommodates the secondary peak(s). A total of 82 healthy human immunodeficiency virus (HIV)-seronegative subjects were administered a single 600-mg dose of amprenavir as part of adult AIDS Clinica...
