RAX-2 is a 3U CubeSat that is studying the formation of plasma irregularities in the ionosphere. The primary payload is a UHF radar receiver which is used in conjunction with ground-based incoherent scatter radar stations to characterize the irregularities. RAX is the first CubeSat funded by the United States National Science Foundation’s Small Satellite Program for Space Weather Research. The ...

[1] Small-scale ionospheric irregularities and auroral precipitation are common features of the auroral ionosphere, but their spatial association has not been examined on global scales. In this paper, we compare electron and ion precipitation from individual passes of the Defense Meteorological Satellite Program (DMSP) spacecraft with concurrent observations of ionospheric irregularities and pl...

the oil and protein content of three varieties of water melon seeds namely, chillian black, dixy queen and charlston gray were determined. the soluble proteins were studied and measured by paper chromatography and amino acid analyzer. the results indicated that oil content of the seeds was 43, 53 and 45% and protein content was 27, 23, and 34% respectively. the soluble proteins contained all th...

The subject of irregularities of distribution arises from uniform distribution, but is of independent interest, and owes its current prominance to the fundamental contribution of K.F. Roth [23–27] and W.M. Schmidt [28–38]. While the theory of uniform distribution may be described as qualitative, the theory of irregularities of distribution is definitely quantitative in nature, as one seeks to m...

Marked anomalies, previously unresolved, exist in the CD spectra of oligoadenylates and oligouridylates at the pentamer or tetramer stage, indicating that these molecules differ in conformation from the preceding and the following member of the series. The CD of oligoadenylates retains a positive Cotton effect even at 80 degrees C. Caution must be exerted when predicting oligonucleotide structu...

Let d ≥ 0 be a fixed integer. Suppose X = (x1, x2, x3, . . .) is a sequence in [0, 1) with the property that for every n ≤ N , each of the intervals [ k−1 n , k n ), 1 ≤ k ≤ n, contains at least one xi with 1 ≤ i ≤ n+d. We show that this implies that N = O(d). This is a generalization of a question raised by Steinhaus some 50 years ago.

The long-term goal of this project is to study waves, irregularities, and propagation in the earth's ionosphere, particularly with respect to GPS. The project has two foci: first, to understand how the ionosphere affects GPS signals and second, how GPS can be used for remote sensing of the ionosphere. In association with these goals, we additionally conduct in situ experiments on satellites and...
