This paper investigates the extent of the holdup underinvestment problem in a buyer-seller relationship in which the seller has private information about his alternative trading opportunities. Theory predicts that, compared with a situation in which outside options are publicly observed, the seller obtains an informational rent while the buyer bears an informational loss. As a result the seller...
The gas–liquid hydrodynamics and mass transfer were studied in a concentric tube internal jet-loop airlift reactor with conical bottom. Comparing standard design, the gas separator was equipped an adjustable deflector placed above riser. effect of riser superficial velocity uSGR on total holdup ?GT, homogenization time tH, overall volumetric liquid-phase coefficient kLa investigated laboratory ...
A model of non-catalytic fast fluidized bed pyrolysis biomass has been developed with the aim investigating relevance secondary heterogeneous reactions between primary products decomposition and char accumulated in bed. The fate extent holdup pyrolyzer have modeled by considering entrainment elutriation particles, attrition, as well drain/regeneration. kinetics pyrolitic is according to a semi-...
The maximum volume of liquid bridge left between two vertically mounted spherical particles has been theoretically determined and experimentally measured. As the gravitational effect has not been neglected in the theoretical model, the liquid interface profile is nonsymmetrical around the X-axis. Symmetry in the interface profile only occurs when either the particle size ratio or the gravitatio...
AIM As transcutaneous electrical stimulation (TES) increased defecation in children and adults with Slow-Transit Constipation (STC), we performed a pilot study to test if TES can improve symptoms (defecation and soiling) in children with chronic constipation without STC and transit delay in the anorectum. METHODS Children with treatment-resistant constipation presenting to a tertiary hospital...
Some recent literature has concluded that patent remedies result in systematically excessive royalties because of holdup and stacking problems. This article shows that this literature is mistaken. The royalty rates predicted by the holdup models are often (plausibly most of the time) below the true optimal rate. Further, those predicted royalty rates are overstated because of incorrect assumpti...
