Tree level decay amplitudes of near-BPS D-brane configurations are known to exactly reproduce Hawking radiation rates from corresponding black holes at low energies even though the brane configurations describe semiclassical black holes only when the open string couplings are large. We show that a large class of one (open string) loop corrections to emission processes from D-branes vanish at lo...

J. Med. Entomol, 24: 425-430 (1987) ABSTRACT In French Polynesia, the cyclopoid copepod Mesocyclops aspericornis was inoculated into burrows of the land crab Cardisoma carnifex and into tree holes, drums, wells, and tires. It successfully reduced larval populations of Aedes polynesiensis and/or Aedes aegypti by 91-99%. Mesocyclops aspericornis has persisted to date for 29 mo in crab holes and f...

-Data and observations from 1995, 1996 and 1997 wet season surveys of natural and artificial tree holes suggest that hole morphology and size are important predictors of the distribution and abundance of Microvelia cavicola Polhemus. The bugs occurred in 42% of the natural holes sampled and <3% of artificial hole censuses. The distribution of M. cavicola was not associated with holes in particu...

In this paper we present a new algorithm for filtering a grey-level image using as attribute the number of holes of its connected components. Our approach is based on the max-tree data structure, that makes it possible to implement an attribute filtering of the image with linear computational cost. To determine the number of holes, we present a set of diverse pixel patterns. These patterns are ...

Marmosets of the genus Callithrix are specialized in the consumption of tree exudates to obtain essential nutritional resource by boring holes into bark with teeth. However, marmoset preferences for particular tree species, location, type, and other suitable factors that aid in exudate acquisition need further research. In the current study, the intensity of exudate use from Anadenanthera pereg...

Four different conceptual models of metacommunities have been proposed, termed "patch dynamics," "species sorting", "mass effect", and "neutral". These models simplify thinking about metacommunities and improve our understanding of the role of spatial dynamics both in structuring communities and in determining local and regional diversity. We tested whether mosquito communities inhabiting water...

Octomyomermis troglodytis was found infecting Aedes sierrensis larvae in 14.5% of 165 tree holes sampled between 1982 and 1986. Mermithid infections were detected in tree hole waters that ranged in pH from 6.5 to 9.3 and electrical conductivities between 0.10 and 5.11 mmhos/cm. Third and fourth instar larvae were most frequently infected, and most immatures that succumbed to infections died whi...

The principal habitats of immature Orthopodomyia alba and Orthopodomyia signifera are tree holes, though they are occasionally encountered in artificial containers. We collected 929 Or. alba and 17 Or. signifera from 2 plastic trash cans, 2 scrap tires, and a tree hole. All collections were made in an urban residential area in central Illinois.

this research carried out in the rafsanjan pistachio orchard to investigate the effect of n form, manure, k and fe on yield, nut quality and leaf mineral nutrients concentrations of pistacia vera l. cv. fandoghi grafted on badami-riz zarand rootstock. the experiment was as factorial with four factors including; manure (without manure and 10 kg tree-1 sheep manure), n form (ammonium sulfate and ...
