With the development of hypersonic air-breathing propulsion systems, such as supersonic combustion ramjet (Scramjet) and rocket-based combined cycle (RBCC) engines, mixing process airstream with fuel in engine combustor has been drawing more attention. Due to compressibility effects, a condition is significantly inhibited. In present paper, novel strategy wall-jet induced shock waves (WJISW) pu...

Great apes sometimes feed on items of low nutritional value with bioactive secondary compounds. These molecules may be toxic and neophobia is presumed to be an essential factor in avoiding the ingestion of noxious items. The aim of this study is to investigate, in captive orangutans, individual and social learning involved in the discovery and ingestion of new items. We presented novel aromatic...

1. An experiment was done with rats (body-weight 160 g) to study the effects on fat metabolism and body composition of low (10 g/kg)- or high (140 g/kg)- fat diets fed as one meal for one 4 h period/d (meal-feeders) or as six spaced meals/d (nibblers). The daily energy intake/unit metabolic body-weight (body-weight 0.73) was the same for all four groups, and this level of intake was about 80% o...

OBJECTIVE Little is known about human postprandial increase of energy expenditure and satiety-associated hormones in relation to both meal frequency and macronutrient composition. DESIGN Randomized cross-over study with four conditions for each participant. METHODS Seven men and seven women (mean age 23±1.5years) were randomly assigned to the order of intake of a 750kcal drink with the same...

Internet auctions have gained widespread appeal as an efficient and effective means of buying and selling goods and services. This study examines buyer behavior on eBay, one of the most wellknown Internet auction Web sites. eBay’s auction format is similar to that of a second-price, hardclose auction, which gives a rational participant an incentive to submit a bid that is equal to his or her ma...

The pre-B cell receptor (preBCR) plays critical roles in early B cell differentiation. It has been shown that not all muH chains are capable of pairing with surrogate light (SL) chains to form preBCR. Here, we established a novel system to differentially identify two types of early pre-B cell populations in bone marrow and fetal liver of mice, one producing SL-pairing muH chains and the other p...

Lagrangian statistics from millions of particles are used to study the turbulent entrainment mechanism in a direct numerical simulation of a turbulent plane jet at Re(λ) ≈ 110. The particles (tracers) are initially seeded at the irrotational region of the jet near the turbulent shear layer and are followed as they are drawn into the turbulent region across the turbulent-nonturbulent interface (...

Entamoeba histolytica ingests fragments of live host cells in a nibbling-like process termed amebic trogocytosis. Amebic trogocytosis is required for cell killing and contributes to tissue invasion, which is a hallmark of invasive amebic colitis. Work done prior to the discovery of amebic trogocytosis showed that acid vesicles are required for amebic cytotoxicity. In the present study, we show ...
