Renormalization and ∗-product of the Horseshoe maps
… find the renormalization and star-product of the horseshoe maps. And to prove that the star-product of two horseshoe admissible pairs is a horseshoe admissible pair. Then to find the relationship between the zeta function of the star-product of two L(n, m) admissible pairs and the zeta function of …

A Horseshoe Crab (Limulus polyphemus) Demographic Study
We examined various aspects of horseshoe crab populations in conjunction with BioWhittaker, a biomedical company that bleeds horseshoe crabs (Limulus polyphemus) and utilizes their blood for biomedical purposes. We examined mortality rates of bled and unbled crabs by holding crabs in tanks for …

Dynamic Emission Baffle Inspired by Horseshoe Bat Noseleaves
… in bats with nasal pulse emission such as horseshoe bats and can undergo non-rigid deformations large enough to affect their acoustic properties significantly. Behavioral studies have shown that these movements are not random byproducts, but are due to specific muscular action. To …

Geoarchaeological Assessment of Horseshoe Cave (24RB1094, Rosebud County, Montana
Horseshoe Cave is located south of Ashland, Montana and at the northern end of the Powder River Basin. Its earliest documented human use and occupation dates to 2,000 years before the present. Evidence of that past use and occupation includes diagnostic bone and stone tools, hearth features and …

Mass ratios in stellar triple systems that admit horseshoe orbits
… of stellar triple systems that give rise to "horseshoe orbits" in the smallest body. Several configurations are tested according to the initial parameters of mass for each of three bodies and position and velocity for the smallest body. The masses are arranged hierarchically, so as to mimic …

Measurement of three-dimensional horseshoe vortex flow in a duct
… of the three-dimensional flow due to the horseshoe vortex formed at the junction of a flat wall and the leading edge of a Rankine half body. The half body is located between the parallel end walls of a duct to model the situation in turbomachinery where struts and vanes, which generate …

LECTINS FROM THE HORSESHOE CRAB, LIMULUS POLYPHEMUS, REACTIVE WITH BACTERIAL LIPOPOLYSACCHARIDE
… sialic acid-binding lectin from the serum of the horseshoe crab, Limulus polyphemus, was isolated by preparative polyacrylamide slab gel electrophoresis and by ion-exchange chromatography on a column of diethylaminoethyl (DEAE)-Sephadex. The purified lectin precipitates the lipopolysaccharide …

The function of modified echolocation pulses in horseshoe bats (Family: Rhinolophidae)
… in communication. In one of these studies, the horseshoe bat, Rhinolophus clivosus, was found to emit echolocation pulses with an unusual and pronounced upsweep at the end of the echolocation pulse (at the FM component). It was hypothesized that these “modified echolocation pulses” may serve a …

Design and Model-based Approaches for Estimating Abundance of American Horseshoe Crab
The American horseshoe crab (HSC), Limulus polyphemus, is one of four species of horseshoe crabs found throughout the world, and the only one found in North America. It is an economically and ecologically important species throughout its native range from Maine to the Yucatan Peninsula. Harvested …

Selection of Spawning Habitats by Horseshoe Crabs (Limulus polyphemus) along the Complex Connecticut Coast
<p>The Atlantic horseshoe crab (<em>Limulus polyphemus</em>) is a multiple-use resource that has recently come under environmental conflict. This research focused on the Long Island Sound population of horseshoe crabs and aimed to characterize the coastal habitats of Connecticut by various traits …

Subsurgace Correlation of the Snow School Formation, Horseshoe Valley Formation, and Medicine Hill Formation
In this paper, the Medicine Hill Formation, Horseshoe Valley Formation, and Snow School Formation will be correlated using lithology of the very coarse sand. Suggestions will be made for other useful methods of physical correlation.

Geographic variation in the phenotypes of two sibling horseshoe bats Rhinolophus simulator and R.swinnyi
… mechanisms to population divergence in African horseshoe bats (genus Rhinolophus). The two species were sampled from their distributional ranges within southern Africa and several morphometric and echolocation parameters were taken. The relative contributions of adaptation and drift were first …

Molecular phylogenetics and the evolution of high-frequency echolocation in horseshoe bats (Genus Rhinolophus)
Horseshoe bats (genus Rhinolophus) belong to the Old World family Rhinolophidae. They are high-duty cycle bats and many species use echolocation calls dominated by high frequencies (above 60 kHz). Much is known about how they use their echolocation calls, but very little is known about why these …

Reducing post-bleeding mortality of horseshoe crabs (Limulus polyphemus) used in the biomedical industry
… effects of blood extraction on the survival of horseshoe crabs and performed a preliminary investigation into amebocyte maintenance in vitro. Hemolymph volume of L. polyphemus was estimated over a representative size range of adults. Hemolymph volume expressed as a percentage of wet body weight …

Finding the horseshoe nail: Colonization, de-colonoization and counter-colonization in Adult and Community Education.
As the ‘Occupy’ camps have sprung up around the world, there has been a growing understanding of neo-liberalism as a hegemonic global political discourse in which the values of the market have come to dominate all aspects of human endeavour. At the same time, concerns have been expressed about the …
