Reynolds number dependence of scalar fluctuations in a high Schmidt number turbulent jet

The scalar rms fluctuations in a turbulent jet were investigated experimentally, using high-resolution, laser-induced fluorescence techniques. The experiments were conducted in a high Schmidt number fluid (water), on the jet centerline, over a jet Reynolds number range of 30003000 or 6500

Groaning with Creation: ecological spirituality in Laudato Sì

In this sequel to his overview of Pope Francis’ second encyclical in the August issue of Open House, an environmental engineer reflects on the spirituality it advocates

Tropical component of the moss Flora of China

In many ways, it is presumptuous for me to speak on the mosses of the tropical regions of China. Many consider the knowledge about the taxonomy, ecology, and geography of tropical bryophytes inadequate (Pócs 1982; Schuster 1983; Richards 1984), and this is certainly the case for the bryophytes of the tropical regions of China. The taxonomy of Chinese taxa is generally in a state of disarray. Early workers, both Chinese and others, have tended to describe new species based upon minor or inconsequential morphological characters and without apparent reference to related taxa found outside of China. This is clear from recent monographic studies that compared Chinese taxa with taxa throughout the world

First personal modes of presentation and the structure of empathy

I argue that we can understand the de se by employing the subjective mode of presentation or, if one’s ontology permits it, by defending an abundant ontology of perspectival personal properties or facts. I do this in the context of a discussion of Cappelen and Dever’s recent criticisms of the de se. Then, I discuss the distinctive role of the first personal perspective in discussions about empathy, rational deference, and self-understanding, and develop a way to frame the problem of lacking prospective access to your future self as a problem with your capacity to imaginatively empathize with your future selves

Merchant Transmission Investment

We examine the performance attributes of a merchant transmission investment framework that relies on �market driven� transmission investment to provide the infrastructure to support competitive wholesale markets for electricity. Under a stringent set of assumptions, the merchant investment model appears to solve the natural monopoly problem and the associated need for regulating transmission companies traditionally associated with electric transmission networks. We expand the model to incorporate imperfection in wholesale electricity markets, lumpiness in transmission investment opportunities, stochastic attributes of transmission networks and associated property rights definition issues, the effects of the behaviour system operators and transmission owners on transmission capacity and reliability, co-ordination and bargaining considerations, forward contract, commitment and asset specificity issues. This significantly undermines the attractive properties of the merchant investment model. Relying primarily on a market driven investment framework to govern investment is likely to lead to inefficient investment decisions and undermine the performance of competitive markets

Robinson v. Cahill: The “Thorough and Efficient” Clause

In Robinson V. Cahill, the New Jersey Supreme Court unanimously affirmed a trial court invalidation of the state\u27s school finance statute on the basis of the thorough and efficient education clause of the state constitution. This article reviews this case in detail, its genesis, its legal theories, its constitutional guidelines, and its implications for New Jersey and possibly other states

Non-conventional superconducting fluctuations in Ba(Fe1-xRhx)2As2 iron-based superconductors

We measured the static uniform spin susceptibility of Ba(Fe$_{1-x}$Rh$_x$)$_2$As$_2$ iron-based superconductors, over a broad range of doping ($0.041\leq x\leq 0.094$) and magnetic fields. At small fields ($H \le$ 1 kOe) we observed, above the transition temperature $T_c$, the occurrence of precursor diamagnetism, which is not ascribable to the Ginzburg-Landau theory. On the contrary, our data fit a phase fluctuation model, which has been used to interpret a similar phenomenology occurring in the high-$T_c$ cuprate superconductors. On the other hand, in presence of strong fields the unconventional fluctuating diamagnetism is suppressed, whereas 3D fluctuations are found, in agreement with literature
