We have observed coherent time evolution between two quantum states of a superconducting flux qubit comprising three Josephson junctions in a loop. The superposition of the two states carrying opposite macroscopic persistent currents is manipulated by resonant microwave pulses. Readout by means of switching-event measurement with an attached superconducting quantum interference device revealed ...

The coordinated development of the environment and economy is core sustainable development. This research investigated water-quality management by exploring impact socioeconomic activities on water quality associated with a major global city. To achieve this goal, system dynamics (SD) model was developed to capture feedback processes interactions between quality; population; resource; primary, ...

We investigated the spatial distribution of heavy metal above-background (anthropic) contents of Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb, Ti, V, and Zn in Baltimore City surface soils and related these levels to potential contaminating sources. Composite soil samples (0-10 cm depth) were digested using a nitric and hydrochloric extraction technique. Slightly more than 10% of plots exceeded United States...

OBJECTIVE To compare the Better Access to Psychiatrists, Psychologists and General Practitioners through the MBS initiative with the Better Outcomes in Mental Health Care initiative, to test contentions that Better Access is used more often by advantaged major city patients and that the role of GPs has been reduced to that of referrers. DESIGN AND SETTING Analysis of Bettering the Evaluation ...

Th ree contemporary leadership challenges face local governments today. Th e fi rst encourages department heads to more actively work the intersection between political and administrative arenas. Th e second promotes collaborative work, synchronizing city and county boundaries with problems that have no jurisdictional homes. Th e third argues that citizen engagement is no longer optional—it is ...

The objective of the study was to assess the use of helmets in a community where helmet use is mandatory but low as there is no police enforcement. A sample comprising 451 motorcyclists in the city of Mar del Plata, Argentina, was studied in 2006. The following variables were studied: gender, type of motorcycle, weather conditions, time of the day, city area and type of road where motorcyclists...

Active emergency department-based surveillance was conducted to determine the incidence of fatal and nonfatal injuries in an urban, female African American population from 1987 through 1990. Nearly 40% of the women studied sustained one or more injuries that required emergency care or resulted in death. By 1989, violence had surpassed falls as the leading cause of injuries, the rate increased b...

With hospital services comprising an important part of care related to acquired immunodeficiency syndrome (AIDS), and all Medicaid programs becoming major payers of these services, Medicaid policies affect the care that Medicaid recipients with AIDS receive. Many States pay hospitals on the basis of prospective payments that do not vary with patient diagnosis. In contrast, Medicaid programs usi...

The energy master planning process for districts requires an analysis of different scenarios, which include new construction to levels efficiency, major renovation all or some buildings comprising building stock under consideration with Deep Energy Retrofit these buildings, minor renovations energy-related scope work, demolition old buildings. Such modeling Different baselines and constraints w...
