U Se of G Rowth R Etardants in W Heat
In general, lodging has been controlled by restricting nitrogen fertilizer application and/or using short cultivars. Growth retardants can also be used to solve this problem.The objective of this study was to evaluate the effect of rates and application times of three growth retardants on Pioneiro wheat cultivar. The trial was carried out in Viçosa-MG, from May to September 2005, in a factorial...
متن کاملW - symmetries on the Homogeneous Space G / U ( 1 ) r
A construction of W-symmetries is given only in terms of the nonlocal fields (parafermions ψ α), which take values on the homogeneous space G/U (1) r , where G is a simply connected compact Lie group manifold (its accompanying Lie algebra G is a simple one of rank r). Only certain restriction of the root set of Lie algebra on which the parafermionic fields take values are satisfied, then a cons...

Third-generation mobile communication systems will bring a wide range of new services with different quality of service requirements and will open the ability to exploit radio resource management functions to guarantee a certain target QoS, to maintain the planned coverage area and to offer a high-capacity while using the radio resources in an efficient way. RRM functions impact the overall sys...

sels, are employed as surveillanceorganisms for marine pollutants (artificially produced radionuclides, petroleum hydrocarbons, metals, and chlorinated hydrocarbons used industrially and as biocides in coastal waters). Varying degrees of contamination in US coastal waters have been indicated by the elevated levels of these substances in the soft parts of bivalves. [The Sd® indicates that this p...

Images of Mars obtained using the Planetary Camera on the Hubble Space Telescope during 1990 and 1991 are described and analyzed. Multi-spectral images of Mars record the martian season between L~ = 348 and 60 corresponding to late winter and spring in the northern hemisphere. The wavelengths of these observations varied between 230 nm in the ultraviolet and 890 nm in the near infrared. We use ...
