A piezoelectrically actuated ball valve

Bimorph strip composed of two layers of poled piezoelectric ceramic material closes and opens valve. Strip performs like capacitator, allowing initial inrush of current when valve is energized and then only small leakage current flows as valve remains energized

Simultaneous fine structure observation of wind and temperature profiles by the Arecibo 430-MHz radar and in situ measurements

A simultaneous campaign of balloon and radar measurements took place on March 14 to 16, 1984, above the Arecibo 430-MHz radar. This radar was operating with a vertical resolution of 150 m following two antenna beam directions: 15 deg. from the zenith, respectively, in the N-S and E-W directions. The main results concerning the comparison between the flight and simultaneous radar measurements obtained on March 15, 1984 are analyzed. The radar return power profile (S/N ratio in dB) exhibits maxima which are generally well correlated with step-like structures in the potential temperature profile. These structures are generally considered as the consequence of the mixing processes induced by the turbulence. A good correlation appears in the altitude range 12.5 to 19 km between wind shears induced by a wave structure observed in the meridional wind and the radar echo power maxima. This wave structure is characterized by a vertical wavelength of about 2.5 km, and a period in the range 30 to 40 hours. These characteristics are deduced from the twice daily rawinsonde data launched from the San Juan Airport by the National Weather Service. These results pointed out an example of the interaction between wave and turbulence in the upper troposphere and lower stratosphere. Turbulent layers are observed at locations where wind shears related to an internal inertia-gravity wave are maxima

The Devolution of Managed Care Contractor Duties: Analysis and Implications for Public Policy in Managed Behavioral Health Care

This Issue Brief analyzes the devolution of the legal duties assumed by managed care organizations (MCOs) in their contracts with group purchasers. Specifically, this brief examines the delegation of MCO contractual duties related to member care and services to individual network providers by comparing the language used in master contracts between purchasers and MCOs with the language contained in agreements with network health care providers who serve members covered under the master contract

Missing Links: Politics and the Misrecognition of the Sweden Democrats

ABSTRACT: This article critiques prevailing approaches to the study of the Sweden Democrats political party. It argues that political agendas motivate academic and journalistic commentators to adopt a limited definition of the party in their analyses. More specifically, the article examines a recurring question in studies of the party, namely, to what extent it can be linked to openly race ideological and other right-wing extremist forces in Swedish society. It shows that while ideological connections between the party and other radical nationalists are weak, sociocultural connections are strong. Concluding that these connections are overlooked by scholars because they are less politically incriminating, the article calls for a paradigm shift in the study of the Sweden Democrats, one that addresses the party as the dynamic movement it is
