The High Energy Stereoscopic System (H.E.S.S.) is a system of four, imaging, atmospheric Cherenkov telescopes in Namibia, designed to detect very-high-energy γ rays above ∼ 100 GeV. During 2002–2003, H.E.S.S. collected data from two, young and energetic radio pulsars: the Crab and PSR B1706−44. We searched for pulsations at the lowest energies that H.E.S.S. is capable of detecting, aiming at a ...

A solution to the σ problem — that of finding a mechanism capable of converting Poynting energy flux to particle-borne energy flux in a pulsar wind — was proposed several years ago by Coroniti and Michel who considered a particular prescription for magnetic reconnection in a striped wind. This prescription was later shown to be ineffective. In this paper, we discuss the basic microphysics of th...

The diet of tripletail, Lobotes .I'urinamellsis, collected from the Mississippi Sound and Mississippi's offshore waters of the Gulf of Mexico between April and September 1995-1997, was investigated through analysis of stomach contents. Of 178 tripJctail stomachs examined, 136 (76%) contained prey items, and 42 (24%) were empty. TripletaiJ with prey in their stomachs ranged from 183 to 787111111...

HIGHLIGHTS Crab apples that could not be consumed were evaluated. Turkish delight is colored with crab apple anthocyanins instead of synthetic colorants. phenolics have added functional properties to Rose-flavored delight.

In order to improve the luminosity, two crab cavities have been installed in KEKB HER and LER [1]. Since there is only one crab cavity in each ring, the crab cavity generates a horizontally titled bunch along the whole ring. The achieved specific luminosity with crabbed bunch is higher, but it is not as high as that from beam-beam simulation [2]. One of the suspicions is the electron cloud. The...

The International Linear Collider (ILC) has a 14 mrad crossing angle in order to aid extraction of spent bunches. As a result of the bunch shape at the interaction point, this crossing angle at the collision causes a large luminosity loss which can be recovered by rotating the bunches prior to collision using a crab cavity. The ILC baseline crab cavity is a 9-cell superconducting dipole cavity ...

In a field experiment, the bumblebee, B. ternarius, visited milkweed patches harboring crab spiders, Misumena atia, at a lower frequency than patches free of crab spiders, and honeybees showed a similar but non-significant trend. Two other bumblebee species, B. terricola and B. agans, did not avoid the spider patches. The latter two species are larger than B. ternarius and honeybees and suffer ...

Cadmium, a metal widely used in industrial processes, has been recognized to be a highly toxic and dangerous environmental pollutant. These excess amounts in addition to naturally occurring levels gradually build up to toxic levels causing damages to the biota of the aquatic ecosystem. The fresh water field crab, Paratelphusa hydrodromous is an important human food source in parts of South Indi...

Chemical cancer risk assessment is a literature-dependent task which could greatly benefit from text mining support. In this paper we describe CRAB – the first publicly available tool for supporting the risk assessment workflow. CRAB, currently at version 2.0, facilitates the gathering of relevant literature via PubMed queries as well as semantic classification, statistical analysis and efficie...

-. The beam-beam interaction with a crossing angle and with a compensating crab angle is simulated and treated partially analytically. The crab angle is obtained by transversely deflecting cavities in one case and by a dispersion in the accelerating cavities in another case. Resonances which are excited by the action of the crab cavities are investigated. Tolerances for the cavity voltage and f...
