Crosses between Gossypium barbadense L and Gossypium hirsutum L. (Upland cotton) have produced limited success in introgressing fiber quality genes into the latter. Chromosome substitution lines (CSBL) have complete chromosomes or chromosome arms from G. barbadense, line 3-79, substituted for the corresponding chromosome or arms in G. hirsutum in a near(More)
Cotton (Gossypium hirsutum L) cultivars highly resistant to the southern root-knot nematode (RKN) [Meloidogyne incognita (Kofoid and White) Chitwood] are not available. Resistant germplasm lines are available; however, the difficulty of selecting true breeding lines has hindered applied breeding and no highly resistant cultivars are available to growers.(More)
The successful operation of buried infrastructure within urban environments is fundamental to the conservation of modern living standards. Open-cut methods are predominantly used, in preference to trenchless technology, to effect a repair, replace or install a new section of the network. This is, in part, due to the inability to determine the position of(More)
IEEE FEBRUARY determinantal equation for 8 is easily found. In general, the solution is quite complex; however, for some practical semiconductor parameters , the solution becomes simple. For oo<lWrn-l and ~>1011, it is found that the terms in (8) containing uo and D, can be neglected. Then, the determinantal equation yields the approximate results 8-f k ,(More)
— This paper presents a simulation analysis of distributed Bragg reflectors (DBR's) and their affect on the characteristics of vertical-cavity surface-emitting lasers (VCSEL's). The SimWindows semiconductor device simulator models the close interaction between electrical, optical, and thermal processes present in VCSEL's. This simulator is used to examine(More)
^ but chose to equate it with a postulated Gaskiers-related d 13 C excursion from circa 580 Ma (35). Instead, our data indicate that this globally correlated negative d 13 C excursion is not related to any known glaciation (36). The duration of this excursion is unconstrained; however, given that it is captured within over 100 m of section in Oman (Fig. 1)(More)
