The Test of Everyday Attention (TEA) is designed to measure attention in adults age 18 through 80 years. The test comprises 8 subsets that represent everyday tasks and has three parallel forms. [ 1 ] It assess three aspects of attentional functioning: selective attention , sustained attention , and mental shifting .
In cryptography, the Tiny Encryption Algorithm (TEA) is a block cipher notable for its simplicity of description and implementation, typically a few lines of code.It was designed by David Wheeler and Roger Needham of the Cambridge Computer Laboratory; it was first presented at the Fast Software Encryption workshop in Leuven in 1994, and first published in the proceedings of that workshop.
Techno-economic assessment or techno-economic analysis (abbreviated TEA) is a method of analyzing the economic performance of an industrial process, product, or service. The methodology originates from earlier work on combining technical, economic and risk assessments for chemical production processes. [ 1 ]
In cryptography, XTEA (eXtended TEA) is a block cipher designed to correct weaknesses in TEA. The cipher 's designers were David Wheeler and Roger Needham of the Cambridge Computer Laboratory , and the algorithm was presented in an unpublished technical report in 1997 (Needham and Wheeler, 1997).
Sbectel was first run in conjunction with ORACLE, the auxiliary teletext provider on Channel 4 in the 1980s. Sbectel occupied pages 410-499 within the page space. When ORACLE lost its licence and was replaced by Teletext Ltd. in 1993, Sbectel moved to its own page space on pages 300-399 and became directly run by S4C.
It occurs naturally in willow (), tea, hyacinth, zucchini (Cucurbita pepo). [3] It appears to attract bees as it has a powerful response in their antenna. [4] In a study in mice, Iranian scientists identified 1,4-dimethoxybenzene as the major psychoactive chemical in musk willow (Salix aegyptiaca) by its ability to cause somnolescence and depressed activity.
Triethylaluminium can be formed via several routes. The discovery of an efficient route was a significant technological achievement. The multistep process uses aluminium, hydrogen gas, and ethylene, summarized as follows: [4] 2 Al + 3 H 2 + 6 C 2 H 4 → Al 2 Et 6
The pK a of protonated triethylamine is 10.75, [4] and it can be used to prepare buffer solutions at that pH. The hydrochloride salt, triethylamine hydrochloride (triethylammonium chloride), is a colorless, odorless, and hygroscopic powder, which decomposes when heated to 261 °C. Triethylamine is soluble in water to the extent of 112.4 g/L at ...
