Scalloped cell xanthogranuloma

Histopathology, 1998
Aims:We describe nine cases of scalloped cell xanthogranuloma, a distinct solitary variant of non‐Langerhans cell histiocytoses.Methods and results:In this retrospective clinicopathological study scalloped cell xanthogranuloma mostly occurred on the back or head and neck of young adult males diagnosed as a xanthogranuloma, naevus, or basal cell ...

VERTEBRAL SCALLOPING IN ACROMEGALY

American Journal of Roentgenology, 1971
Roentgenograms of the thoracic and lumbar spine of 38 acromegalic patients were evaluated to determine the frequency of posterior vertebral body scalloping.Scalloping was found in a significant number of patients, particularly in the lumbar region. The occurrence of this sign has not been adequately emphasized in the past.Possible pathogenic mechanisms

Scallops and Scallop Aquaculture in China

2016
Abstract A large number of Pectinid scallops are found along the coast of China, and scallops are among the most important marine resources for China. China leads the world in scallop aquaculture. Scallop aquaculture in China began in the late 1960s and has gone through rapid growth since the 1980s.

Scalloped beam amplification

IRE Transactions on Electron Devices, 1954
Scalloped beam amplification occurs when an rf signal propagates along an electron beam of periodically varying diameter whose scallop wavelength is adjusted to be one-half the effective plasma wavelength in the beam. The dependence of this gain mechanism on frequency, magnetic field, voltage, and current has been investigated experimentally, and over ...

The ‘acoustic scallop’: a bubble-powered actuator

Journal of Micromechanics and Microengineering, 2006
The device described here consists of a millimeter-size tube immersed in a liquid, closed at one end, and partially filled with gas. A sound field in the liquid causes the gas volume to pulsate alternately expelling and drawing liquid through the open end of the tube. According to general fluid mechanical principles, the liquid exits the tube as a jet,

Mortality of Scallops on a Manx Scallop Bed Due to Fishing

Journal of the Marine Biological Association of the United Kingdom, 1972
Mortality resulting from fishing of scallops (Pecten maximus L.) can be divided into the loss caused by their removal for marketing and the indirect damage inflicted during the operation both by the dredges on the sea bed and the rough handling of undersized discards on board the boat (Medcof & Bourne, 1964; Caddy, 1968).

Swimming in Scallops

2016
Abstract Pectinids are among the few bivalves that swim, with the prime motivation of escaping their predators. Swimming engages the large adductor muscle to close the valves, the hinge ligament to open them after muscle relaxation and the muscular mantle to direct the jets.
