the hydrodynamic behavior of approaching flow and the amount of sediment entry into right-angled lateral intakes in diversion dams were investigated using a laboratory channel by experimental measurement and observation. the velocity field upstream of the intake in the main channel and before it at the sluice gate was measured at different elevations of flow at different discharge rates of the ...
Products of cytochrome P-450 enzymes may play a role in capacitative Ca2+ entry in endothelial cells, which can promote a rise in vascular permeability. Thapsigargin (150 nM) stimulated capacitative Ca2+ entry and increased the capillary filtration coefficient ( K f,c) in isolated normal canine lung lobes. Pretreatment of the lobes with cytochrome P-450 inhibitors clotrimazole (10 μM) or 17-oct...
BACKGROUND Although prevalence of heart failure (HF) is similar in women and men, more men are admitted to specialized HF clinics, possibly owing to a perception that men benefit more. Our aim was to describe 1-year outcomes in men and women attending specialized HF clinics. METHODS AND RESULTS We enrolled 531 newly referred patients (mean age 66 years, 26% women) to 1 of 6 HF multidisciplina...
BACKGROUND The independent prognostic value of elevated jugular venous pressure or a third heart sound in patients with heart failure is not well established. METHODS We performed a retrospective analysis of the Studies of Left Ventricular Dysfunction treatment trial, in which 2569 patients with symptomatic heart failure or a history of it were randomly assigned to receive enalapril or placeb...
In a screen for early developmental mutants of the zebrafish, we have identified mutations specifically affecting the internal organs. We identified 53 mutations affecting the cardiovascular system. Nine of them affect specific landmarks of heart morphogenesis. Mutations in four genes cause a failure in the fusion of the bilateral heart primordia, resulting in cardia bifida. In lonely atrium, n...
HCN channels are the molecular subunits of native funny (f-) channels of cardiac pacemaker cells and neurons. Although funny channels were first functionally described in cardiac cells in the late 1970s, cloning of HCN channels, of which four subunits are known today (HCN1-4), had to wait some 20 years to be accomplished, which delayed the investigation of HCN-related channelopathies. In cardia...
This paper reconsiders the well known comparison of equilibrium entry levels into a Cournot industry under free entry and under the two commonly used socially optimal schemes. Allowing for the possibility of increasing returns to scale in production, this paper generalizes the conclusion of [Mankiw and Whinston, Rand J. 1986], that free entry yields more rms than the second-best socially optim...
We show that an auctioneer may prefer to restrict entry by exacting an admission fee to having an extra potential bidder in an auction setting with endogenous bidder entry. We also highlight that admission fees and reserve prices are different instruments in a setting with uncertainty over entry costs, and that optimal mechanisms in such settings may be higher-dimensional than in Myerson (1981)...
