The western black-legged tick, Ixodes pacificus, was collected from Huff Canyon in the Sutter Buttes in north central California, Sutter County. The Sutter Buttes are within the Sacramento Valley and outside the normal distribution of I. pacificus in California. Adult I. pacificus were collected via flagging as they quested along deer trails; subadult life stages were collected from three speci...

The spatial distribution pattern of hospitals in Wuhan indicates a core in the central urban areas and a sparse distribution in the suburbs, particularly at the center of suburbs. This study aims to improve the gravity and Huff models to analyze healthcare accessibility and resources. Results indicate that healthcare accessibility in central urban areas is better than in the suburbs, where it i...

Business strategy represents the choice of how to compete for competitive advantage (Porter, 1980, Porter, 1985). And Strategic Information Systems (SIS) shape (Rackoff et al., 1985, Wiseman, 1985) and enable (Bensaou and Venkatraman, 1995) that business strategy. SIS has been the focus of a large body of research and anecdotal descriptions (Chan and Huff, 1992, Porter and Millar, 1985, Wiseman...

In this paper we empirically analyze several algorithms for solving a Huff-like competitive location and design model for profit maximization in the plane. In particular, an exact interval branch-and-bound method and a multistart heuristic already proposed in the literature are compared with uego (Universal Evolutionary Global Optimizer), a recent evolutionary algorithm. Both the multistart heu...

Heat extraction from deep, hot rocks for energy production is based on water circulation through a man made fracture or natural fractures. As multiple and non-planar fractures in a stress field affect the geothermal reservoir behavior, so the capability to simulate multiple fractures and joints is needed to help reservoir design and operation. A 3D model is developed in this work to simulate an...

The reported incidence of gout and hyperuricaemia in polycythaemia vera has varied in different series. Thus Tinney, Polley, Hall, and Giffin (1945) reported clinical gout in 4 7 per cent. of 168 cases, Videbaek (1950) in 9 per cent. of 125 cases, and Lawrence, Berlin, and Huff (1953) in 7 per cent. of 159 patients, and unspecified arthritis in a further 14 per cent. On the other hand, Wasserma...

That most of the vitamin B6 taken in the body is excreted in the urine as 4-pyridoxic acid (PIC), has been reported by Huff (1), Sarett (2), Butler (3) and MƒÓller (4), and its simple method of estimation has been discussed from various angles. It has also been found that of the three forms of vitamin B6, PIC excretion from pyridoxal (PAL) is most rapid and large in amount, possibly due to the ...
