Jones method

Figure 18.12 The electron-density map is interpreted by fitting into it pieces of a polypeptide chain with known stereochemistry such as peptide groups and phenyl rings. The electron density (blue) is displayed on a graphics screen in combination with a part of the polypeptide chain (red) in an arbitrary orientation (a). The units of the polypeptide chain can then be rotated and translated relative to the electron density until a good fit is obtained (b). Notice that individual atoms are not resolved in such electron densities, there are instead lumps of density corresponding to groups of atoms. [Adapted from A. Jones Methods Enzym. (eds. H.W.

Upon completion of data collection, estimation of values for the remaining compounds was performed. The estimates are primarily based on the methods of Shebeko (16) and Jones (2). The Jones method (regression of the stoichiometric concentrations for volume % fuel in fuel plus air) is shown below ... 

The bromination-dehydrobromination route is in many cases preferable [Scheme 2 80JCS(P1)2081], using bromine, N-bromosuceinimide (NBS), or phenyltrimethylammonium tribromide (PTAB). The resulting mono-bromo, geminal, or vicinal dibromo and tribromo derivatives (e.g., 5a,b) are often preferentially dehydrobrominated by Jones method [73JCS(P1)968] using lithium salts in dimethylformamide (DMF). Bases such as triethyla-mine, sodium methoxide, and l,8-diazabicyclo[5.4.0]undec-7-ene (DBU) were also used. 

Another important advantage of using a response surface methodology based method, like Jones method, is that a mathematical model is used to describe the response as a function of the product design and environmental variables. Using this model, interpolations of the product...

The particular case of the hardness of rollers is covered by ISO 726734 36 which is in three parts dealing with the normal dead load method, Shore durometer and the Pusey Jones methods respectively. This last method is a very old hardness test which is now virtually never seen, although it is understood to still be popular in some circles for rollers. It is an amazing brass and chain contraption that uses a 3.175 mm indentor acting under a load of 1kg and without a surrounding foot. 

The two most common methods used to correct resolved peak profiles for the broadening imposed by the finite width of the X-ray beam in the diffractometer, are due to Jones (15) and Stokes (16). Both are essentially unfolding or deconvolution methods, but the Jones method defines specific functions for both the uncorrected and the instrumental broadening profile. If the uncorrected profile is Gaussian, then... 

The methods in general use for separating the size and distortion broadening components of the resolved and corrected peak profiles can be separated into two groups, non-transform and transform methods. The non-transfona methods are essentially similar to the Jones method, being approximations to a convolution. The transform method discussed here makes use of the Fourier coefficients found after the Stokes correction.

This mixture was saponified with methanolic potassium hydroxide to give the two epimers of 267 in quantitative yield. By enol acetylation, 267 was converted to 268 which in turn was oxidized by osmium tetroxide and periodate to the noraldehydes 269. The mixture 269 was converted to 270 via oxidation, esterification, and mild alkaline hydrolysis. The hydroxyesters 270 were oxidized by the Jones method to afford the single crystalline diketoester 271. Ketalization of 271 yielded the ketal 272 in quantitative...

The Jones method is rapid and the yields high. The main limitation is the low solvent power of acetone. However, the method was used successfully by Eisen-braun for oxidation of cyclooctanol to cyclooctanone on a fairly large scale. 

Other oxidation procedures were used, e.g., pyrldinium chlorochromate (Corey s reagent), and dipyridine Cr(VI) oxide (Collins reagent), but did not produce yields comparable to the Jones method.
