Along with the widespread application of the electronic commerce in the modern business, the logistic distribution has become increasingly important. More and more enterprises recognize that the logistic distribution plays an important role in the process of production and sales. A good routing for logistic distribution can cut down transport cost and improve efficiency. In order to cut down tr...

In generosity games, one agreement payoff is exogenously given, whereas the other is endogenously determined by the proposer’s choice of the ”pie” size. This has been shown to induce pie choices which are either efficiency or equality seeking. In our experiment, before playing the generosity game, participants are asked to buy their role via a random price mechanism. This should entitle them to...

BACKGROUND Aspiration can cause a diverse spectrum of pulmonary disorders some of which can lead to death but can be difficult to diagnose. PATIENTS AND METHODS The medical records and autopsy findings of 57 consecutive patients in whom aspiration was the immediate cause of death at Mayo Clinic (Rochester, MN, USA) over a 9-yr period, from January 1 2004 to December 31 2012 were analyzed. R...

BACKGROUND Limited information exists about the nature of and factors associated with oropharyngeal aspiration (OPA) and silent aspiration (SA) in children. A prospective study was undertaken to determine the factors associated with fluoroscopically identified OPA and SA. METHODS Three hundred children presenting with feeding difficulties underwent a videofluoroscopic swallow study (VFSS) for...

Due to the entry of Taiwan into WTO and the recently liberalized Petroleum Management Law, the oil market in Taiwan is liberalized and thus is becoming more competitive. However, the space limitation and the residents’ increasing awareness of environmental protection issues in the island make international vendors unavoidably have to rent tanks from domestic oil companies. In order to help the ...

Nebulizer drug output rate increases during the nebulization. For unvented jet nebulizers, a physical and mathematical model based on the efficiency of the nebulization process is presented for this phenomenon. Formulas are derived for the cumulative drug output and the drug output rate of the nebulization process. The model is compared with the model proposed by Coates et al. [J. Aerosol. Med....

Aspiration pneumonia and aspiration pneumonitis are associated with significant morbidity in veterinary and human medicine. A variety of medical conditions and medications can predispose patients to aspiration, and every precaution should be taken to prevent aspiration from occurring. For dogs that aspirate oral or gastric contents and subsequently develop pneumonia, monitoring and supportive c...

I analyze an economy with uncertainty in which a set of indivisible objects and a certain amount of money is to be distributed among agents. The set of intertemporally fair social choice functions based on envy-freeness and Pareto efficiency is characterized. I give a necessary and sufficient condition for its non-emptiness and propose a mechanism that implements the set of intertemporally fair...
