The insulin radioimmunoassay technique used for human insulin has been modified for measuring rabbit insulin (i) at lower concentrations of insulin in plasma, and (ii) more precisely. Eleven algebraic functions were fitted in turn to fifty-three data sets. The goodness-of-fit was assessed in each case. It was concluded that a quadratic equation was the best function for the standard curve of th...

The enzyme-linked immunosorbent assay (ELISA) is often used to measure protein levels in plasma and other solutions. In order for the assay to be quantitative, a standard curve must be prepared for each assay. Technical blunders in preparing the standard curve can render otherwise representative sample values useless. In order to recover these data, a protocol has been developed whereby a new s...

When rails are laid in a railway track, small gaps are left between the ends of adjoining rails to allow for the expansion of the rails when the temperature rises. Rail joints are provided to form a continuous rail path which are normally laid in standard lengths bolted together by fishplates. When two rail joints are exactly opposing each other, they are called square (side by side) joints...

in this paper, we give some characterizations for legendre spherical, legendre normal and legendre rectifying curves in the 3-dimensional sasakian space. furthermore, we show that legendre spherical curves are also legendre normal curves. in particular, we prove that the inverse of curvature of a legendre rectifying curve is a non-constant linear function of the arclength parameter.
