Potentialities of TEC topping: A simplified view of parametric effects [PDF]

open access: yes, 1980
An examination of the benefits of thermionic-energy-conversion (TEC)-topped power plants and methods of increasing conversion efficiency are discussed. Reductions in the cost of TEC modules yield direct decreases in the cost of electricity (COE) from TEC-

Severe B Cell Deficiency in Mice Lacking the Tec Kinase Family Members Tec and Btk [PDF]

open access: yes, 2000
The cytoplasmic protein tyrosine kinase Tec has been proposed to have important functions in hematopoiesis and lymphocyte signal transduction. Here we show that Tec-deficient mice developed normally and had no major phenotypic alterations of the immune ...

Thermomechanical Analysis of Various Solid-oxide-fuel-cell Components Using Simple Analog Micrometer Measurements

open access: yesMakara Journal of Science, 2020
The solid oxide fuel cell (SOFC) is a device that can convert the energy stored in gaseous chemicals such as hydrogen into electricity. Because SOFCs are operated at high temperatures, their structures must be stable and durable.

Estimativa e Propagação de Valores de DCB C1C-C2W de um Receptor GPS com Vistas a Correção de Ordem Superior do Efeito Ionosférico

open access: yesRevista Brasileira de Cartografia, 2020
Quando se almeja maior acurácia no posicionamento GNSS, é imprescindível a correção dos efeitos de ordem superior da refração ionosférica. O erro associado à ionosfera é diretamente proporcional ao conteúdo total de elétrons (Total Electron Content – TEC)
