a module is said to be $pi$-extending provided that every projection invariant submodule is essential in a direct summand of the module. in this paper, we focus on direct summands and indecomposable decompositions of $pi$-extending modules. to this end, we provide several counter examples including the tangent bundles of complex spheres of dimensions bigger than or equal to 5 and certain hyper ...

Commodity bundling is studied in an environment where the dispersion of valuations unambiguously decreases when two or more goods are sold as a bundle only. Bundling is more likely to dominate separately selling the goods if marginal costs are low relative to the average valuation, or if the distribution of valuations is very peaked around the mean. ∗This note unbundles results previously provi...

conclusions the intervention bundle prompted increased administration of psdivc and documentation. similar centres may benefit from an intervention to improve compliance. results sixty-four patients in group a underwent turbt prior to introduction of the intervention bundle. fifty-four patients had non-muscle invasive bladder cancer (nmibc), which would have been eligible for psdivc. fifteen (2...

acute yew (taxus baccata) intoxication was induced in 7 adult sheep by oral administration of the plant materials at the dose of 2.5g/kg body weight. blood samples for hematology and serum biochemistry were collected before and after the induced intoxication.electrocardiography was performed using a base-apex lead. intoxicated animals displayed lethargy, depression, bradycardia and varying inte...

PURPOSE The purpose of this study was to compare the bundle tension curves and resultant knee kinematics between 2 tensioning protocols in anatomic double-bundle anterior cruciate ligament (ACL) reconstruction. METHODS Anatomic double-bundle ACL reconstruction was performed in 7 male cadaveric knees. Each graft was tensioned to 22 N under 2 conditions: (1) both bundles tensioned at 20 degrees...

  The anterior cruciate ligament (ACL) is composed of two bundles, which work together to provide both antero-posterior and rotatory stability of the knee. Understanding the anatomy and function of the ACL plays a key role in management of patients with ACL injury. Anatomic ACL reconstruction aims to restore the function of the native ACL. Femoral and tibial tunnels should be placed in their an...
