Recommendations for applying nitrogen (N) fertilizer in autumn involve delaying applications until daily soil temperature at 10-cm depth is #10 C. Daily soil temperature data during autumn were examined from 26 sites along a transect from 36 to 49 N latitude in mid-continent USA. After soils first cooled to #10 C (First10), temperatures usually rebounded for varying amounts of time before the f...

Robert W. Johnson Alphawave Research, Atlanta, GA 30238, USA (Dated: December 26, 2009) Abstract To investigate the relation between observations of the 10.7 cm flux and the international sunspot number so that a physical unit may be ascribed to historical records, both polynomial and power law models are developed giving the sunspot number as a function of flux and vice versa. Maximum likeliho...

Experiments have been performed on a corona preionization type 10 cm aperture TEA CO2 laser. For a CO2 : N2 : He = 1 : 1 : 7 mixture an output energy of 34 joule per liter and for a 1 : 1 : 10 mixture 40 joule per liter could be obtained. The overall efficiency is about 18%. The time behaviour of the current and voltage of the system shows a delay of several hundreds of nanoseconds after the pr...

A high-resolution accelerometer with a bulk-micromachined silicon proof mass and an interferometric position sensor was developed for measuring vibratory accelerations. The interferometer consists of interdigitated fingers that are alternately attached to the proof mass and support substrate. Illuminating the fingers with coherent light generates a series of diffracted beams. The intensity of a...

Gastrointestinal stromal tumor (GIST) is a relatively rare type of cancer that affects an estimated 5000 to 10,000 new people each year in the US. Most GIST tumors develop in the stomach; but they can also arise in the small intestine, colon and rectum, esophagus or abdominal cavity. Gastrointestinal stromal tumors are the most common mesenchymal, nonepithelial tumors of the gastrointestinal tr...

Sufficient (almost necessary) conditions are given on the weight functions u(·), v(·) for Φ−1 2 [ ∫ Rn Φ2 ( C2(Msf)(x) ) u(x)dx ] ≤ Φ−1 1 [ C1 ∫ Rn Φ1(|f(x)|)v(x)dx ] to hold when Φ1, Φ2 are φ-functions with subadditive Φ1Φ 2 , and Ms (0 ≤ s < n), is the usual fractional maximal operator. §

We review recent progress in the gauging of maximal supergravity theories.

Let X be a Tychonoff space and A a subalgebra of C(X) containing C∗(X). Suppose that CK(X) is the set of all functions in C(X) with compact support. Kohls has shown that CK(X) is precisely the intersection of all the free ideals in C(X) or in C∗(X). In this paper we have proved the validity of this result for the algebra A. Gillman and Jerison have proved that for a realcompact space X, CK(X) i...
