This paper presents the heat transfer and pressure drop characteristics of a primary surface heat exchanger (PSHE) with corrugated surfaces. The PSHE was experimentally investigated for a Reynolds number range of 156–921 under various flow conditions on the hot and cold sides. The inlet temperature of the hot side was maintained at 40 ̋C, while that of the cold side was maintained at 20 ̋C. A c...

In [k]n = [k]×[k]× · · ·×[k], a line consists of the collection of points where all but one coordinate is fixed and the unfixed coordinate varies over all possibilities. We consider the problem of marking (or designating) one point on each line in [k]n so that each point in [k]n is marked either a or b times, for some fixed a or b. This is equivalent to forming a strategy for a hat guessing gam...

Species–area relationships are amongst the most studied ecological phenomena (Connor & McCoy, 1979; Rosenzweig, 1995; Whittaker, 1998; Báldi & McCollin, 2003; HornerDevine et al., 2004; Martin & Goldenfeld, 2006). They encapsulate the general pattern that larger islands/areas contain more species than smaller ones (e.g. MacArthur & Wilson, 1967). Although there is strong evidence for the genera...

One of the most exciting results of the Spitzer era has been the ability to construct longitudinal brightness maps from the infrared phase variations of hot Jupiters. We presented the first such map in Knutson et al. (2007), described the mapping theory and some important consequences in Cowan & Agol (2008) and presented the first multi waveband map in Knutson et al. (2008). In these proceeding...

Eleven dogs with spontaneous neoplasms were Intensively treated with an ¡mmunoadsorption system consisting of a contin uous flow centrifuge, Protein A-Sepharose columns, and a semi automatic elution system. Despite consistent and substantial lowering of immunoglobulin G levels, tumor regression was noted in only one of 11 dogs. In contrast, infusion of small volumes of plasma after incubation ...

Let E(n) and T(m) for nonnegative integers n and m denote the Johnson–Wilson and the Ravenel spectra, respectively. Given a spectrum whose E(n)∗–homology is E(n)∗(T(m))/(v1, . . . , vn−1), then each homotopy group of it estimates the order of each homotopy group of LnT(m). We here study the E(n)–based Adams E2 –term of it and present that the determination of the E2 –term is unexpectedly comple...

We show that the Ginsparg-Wilson (GW) relation can play an important role to define chiral structures in finite noncommutative geometries. Employing GW relation, we can prove the index theorem and construct topological invariants even if the system has only finite degrees of freedom. As an example, we consider a gauge theory on a fuzzy two-sphere and give an explicit construction of a noncommut...
