A simple and inexpensive method was developed using liquid - liquid extraction, together with high performance chromatographic method for determination of methoxyfenozide residues in grapes. The evaluated parameters include the extracts by distilled water and acetonitrile solvents. The method was validated using grapes samples spiked with methoxyfenozide at different fortification levels (0.05, 0.1 and 0.5 µg/g). Average recoveries (using each concentration three replicates) ranged 86-95 %, with relative standard deviations less than 5%, calibration solutions concentration in the range 0.

In this paper, we will make explicit the error in the mean value and the standard deviation when using different types of distribution laws. We also employ the principle of maximum entropy as a criterion to choose among the truncated Gaussian, the fitted Gaussian and the lognormal distribution.

Trong các tập san y học, chúng ta thường thấy những cột số dưới hình thức x ± y, trong đó x là số trung bình, còn y thì có khi là độ lệch chuẩn (standard deviation – SD) hay sai số chuẩn (standard error – SE). Cũng có tác giả viết SEM (viết tắt từ cụm từ standard error of the mean).

The transport of oxygen in the hemolymph of many arth-ropod and mollusc species is mediated by large copper-proteins that are referred to as hemocyanins. Arthropod hemocyanins are composed of hexamers and oligomers of hexamers. Arachnid hemocyanins usually form 4·6-mers consisting of seven distinct subunit types (termed a–g), although in some spider taxa deviations from this standard scheme have been observed.

HUMAN CAPITAL INVESTMENT BY PRIVATE EMPLOYERS IN BLAIR COUNTY, PENNSYLVANIA, AS MEASURED A one standard deviation (0.28) increase in the choice index corresponds with a reduction in mean scores of only about four points, about one-eighth of an MSA-level standard deviation. Moreover, in some alternative specifications not reported here, the coefficient estimate is statistically insignificant, though still negative.

a a For a 0, let W1 (t) and W2 (t) be the a-neighbourhoods of two independent standard Brownian motions in Rd starting at 0 and observed until time t. We prove that, for d ≥ 3 and c 0, t→∞ t(d−2)/d lim 1 κ a a log P |W1 (ct) ∩ W2 (ct)| ≥ t = −Id a (c) κ and derive a variational representation for the rate constant Id a (c). Here, κa is the Newtonian capacity of the ball with radius a. We show that the optimal a a strategy to realise the above large deviation is for...

Abstract X-ray crystal structure determination of agglutinin from abrus precatorius in Taiwan is presented. The crystal structure of agglutinin, a type II ribosome-inactivating protein (RIP) from the seeds of Abrus precatorius in Taiwan, has been determined from a novel crystalline form by the molecular replacement method using the coordinates of abrin-a as the template. The structure has space group P41212 with Z = 8, and been refined at 2.6 Å to R-factor of 20.4%. The rootmean-square deviations of bond lengths and angles from the standard values are 0.009 Å and 1.3°.
