All you can drink” specials are forbidden by law in several places. Authorities claim that establishments tend to offer low quality drinks when they use this type of promotion. In this paper, I elaborate a model to determine whether a monopolist produces higher or lower quality goods when using buffet pricing (all you can drink) instead of a two-part tariff. I find that the more profitable stra...

Besides its original purpose of reducing wave drag at transonic speed it has been shown that shock control bumps (SCB) can additionally be used for buffet alleviation. Considering 3-D-SCBs as a novel sort of vortex generators these bumps introduce, when carefully designed, streamwise vorticity into the flow and thereby prevent the boundary layer (BL) from early separation. The current paper pre...

Centrally administered glucagon-like peptide-1 (GLP-1) inhibits feeding in fasted rats, but its role in human satiety has been largely unexplored. The present study investigated the effect of peripheral GLP-1 infusion on gastric emptying and satiety in man. Ten non-obese male subjects were infused in a randomized single-blind within-subject crossover study using saline infusion as control. They...

Previous cross-sectional studies have shown that sedentary males, unlike their active counterparts, are unable to compensate for previous energy intake (EI). The present study therefore investigated the effects of a 6-week moderate exercise programme (4 times per week, 65-75 % maximal heart rate) on appetite regulation in healthy sedentary volunteers using a longitudinal design. EI at a buffet ...

Background: Prebiotics have been shown to improve satiety in adults with overweight and obesity; however, studies in children are limited.Objective: We examined the effects of prebiotic supplementation on appetite control and energy intake in children with overweight and obesity.Design: This study was a randomized, double-blind, placebo-controlled trial. Forty-two boys and girls, ages 7-12 y, w...

The present study aimed to investigate whether substrate metabolism, appetite and feeding behaviour differed between high and low energy turnover conditions. Thirteen overweight premenopausal women completed two 1 d trials: low energy turnover (LET) and high energy turnover (HET), in a randomised, cross-over design. In LET, subjects consumed a test breakfast (49% carbohydrate, 37% fat, 14% prot...

OBJECTIVES In July 2 2010, a diarrhea outbreak occurred among the workers in a company in Gyeungju city, Korea. An epidemiological investigation was performed to clarify the cause and transmission route of the outbreak. METHODS We conducted a questionnaire survey among 193 persons, and we examined 21 rectal swabs and 6 environmental specimens. We also delegated the Daegu Bukgu public health c...

In this work, computational fluid dynamics simulations are carried out to assess the ability of control surfaces alleviate or suppress transonic buffet. Among available surfaces, upper trailing edge flaps were considered since they modify aerofoil pressure distribution and fix shock at an upstream position. Spoilers also studied as produce a similar effect by interfering with disturbance propag...

Recent work on proof-based verifiable computation has resulted in built systems that employ tools from complexity theory and cryptography to address a basic problem in systems security: allowing a local computer to outsource the execution of a program while providing the local computer with a guarantee of integrity and the remote computer with a guarantee of privacy. However, support for progra...
