Abstract
A diverse mixture of volatile headspace analytes containing compounds with boiling points covering a range from β196Β°c to 145Β°c can be separated in approximately 40 minutes by multidimensional HRGC. The described provisional MDβHRGC Systems employ cryogenic sample collection, four 0.53 mm FSOT columns, and multiβramp temperature programming of either one or two ovens. Enhanced sensitivity for organic species and minimal interference from water vapour in the samples can be obtained by a MDβHRGC configuration that uses separate ovens, appropriate column switching operations, and TCD + FID detection.

## Abstract This paper presents a 2D array design composed of rectangular slot antennas tuned with patch stubs. The 2D array of 32 Γ 32 elements for phasedβarray applications achieves a 38βdB gain, 60% impedance bandwidth, and 65Β° scanning angle without grating lobes. The return loss, radiation pat
Generalized correlations are evolved to predict friction factors and convective heat transfer coefficients with twisted tapes in a tube for a wide range of Reynolds numbers and Prandtl numbers. Satisfactory agreement between the present correlations and the data of others validate the proposed corre
achieved nowadays and the high complexity of modem control units, the test procedures have to cover a wider number of test items in less time. We realized a system which is able to perform the fail safe test by making the conditions automatically, as well as to confirm the ABS control by a real time
