Stable discharges with peak density fe =1.5xlQ15am-3 have been obtained in deuterium at BT =8.7T in the Alcator tokamak. Complete thermal equilibration between electrons and ions is observed, with peak temperatures of 900eV. The maximum value of fiTE is 3x1013cm-3.s. . Nearly classical behaviour, from the viewpoint of energy confinement, is observed. At the highest densities, a regime is attain...

We discuss the thermoelectric (TE) transport in billiard systems of interacting particles, coupled to stochastic particle reservoirs. Recently in [1], analytical exact expressions for the TE transport of noninteracting gases of polyatomic molecules were obtained, and a novel microscopic mechanism for the increase of thermoelectric efficiency described. After briefly reviewing the derivation of ...

considering the efficiency studies play a role in making available the revise in relative importance, policy reforms and resource management, this study has been accomplished in fish beach seine cooperative companies located in golestan province and used dea approach to measure the technical efficiency (te) and factor effects. the survey data were gathered from 20 farms, which selected via cens...

Operative temperature (Te) and standard operative temperature (Tes) models have been used to address ecological questions about the thermal biology of ectotherms and endotherms for over 25 years. This review focuses on the accuracy and use of Te and Tes models in ecological and physiological studies. The utility of Te and Tes models lie in the fact that they take a multivariate problem involvin...

Background/introduction MRI-guided high-intensity focused ultrasound (MRHIFU) therapy can relieve pain associated with metastatic and benign bone tumours in patients who fail to respond to conventional radiation therapy. However, since existing MR-thermometry techniques do not provide temperature information within the bone, HIFU exposures in bone are currently monitored using temperature chang...

Stem cell therapy is a new strategy for chronic ischaemic heart disease in patients. However, no consensus exists on the most optimal delivery strategy. This randomized study was designed to assess cell delivery efficiency of three clinically relevant strategies: intracoronary (IC) and transendocardial (TE) using electromechanical mapping guidance (NOGA) compared to surgical delivery in a chron...

Heat-flow sensing is expected to be an important technological component of smart thermal management in the future. Conventionally, the thermoelectric (TE) conversion technique, which is based on the Seebeck effect, has been used to measure a heat flow by converting the flow into electric voltage. However, for ubiquitous heat-flow visualization, thin and flexible sensors with extremely low ther...

We present a design principle to develop new categories of telluride-based thermoelectric nanowire heterostructures through rational solution-phase reactions. The catalyst-free synthesis yields Te-Bi(2)Te(3) "barbell" nanowire heterostructures with a narrow diameter and length distribution as well as a rough control over the density of the hexagonal Bi(2)Te(3) plates on the Te nanowire bodies, ...

OBJECTIVE Township hospitals (THs) are important components of the three-tier rural healthcare system of China. However, the efficiency and productivity of THs have been questioned since the healthcare reform was implemented in 2009. The objective of this study is to analyse the efficiency and productivity changes in THs before and after the reform process. SETTING AND PARTICIPANTS A total of...
