detection can be substituted for the GHB analysis, but comparatively poor sensitivity towards GBL and 1,4-butanediol is observed. Note that GHB (as GHB ) shows no column retention with this buffer system. Standard Solution Preparation: Prepare a mixed standard of GHB sodium salt (1-10 mg per mL), GBL (5-10 mg/mL), and 1,4-butanediol (1-10

tiveness of the six influence strategies and the conditions under which certain influence strategies are more likely to be used. The concepts of power and influence have been the focus of scholarly attention for several decades (cf. French and Raven 1959; Spekman 1979). In contrast, research on influence strategies that people use to translate
10 The general influence of Horace Bushnell on Olmsted and the influence of his sermon, "Unconscious Influence"11 is also well documented.12 However, further examina tion of Bushnell's writings revealed more evidence of the direct influence of Bushnell on Olmsted, including Olmsted's practice of landscape design and theories of city .
More specifically, the study aims to understand the influence of Family, Friends and community on individuals' intention to adopt Bitcoin, which is the world's most popular virtual currency. 3.

diphenylmethane diisocyanate, and 1,4-butanediol, the prepoly-mer method was used. The increase of the HS content increased the contribution of the associated by hydrogen bond urethane groups and decreased the degree of micro-phase separation in the PUs synthetized with PPGþPTHF blends, an increase of the thermal stability was also obtained.

The graphical representation of the moment effect generated by the movement of a unit load on the beam is known as the influence line. Influence lines and influence surfaces are commonly used to calculate maximum and minimum force effects at a specified point on a
