The use of thioxopyrimidine derivatives for the regulation of vegetative growth of wheatThe work is devoted to the screening of new effective wheat plant growth regulators based on synthetic compounds, thioxopyrimidine derivatives. The wheat (Triticum aestivum L.) variety Oksamit Mironivskyi was used as the object of the study. Morphometric parameters (average length of shoots and roots (mm), and avAuxinerage biomass of 10 plants (g)) of 4-week-old wheat plants were measured. Treatment of wheat plants with thioxopyrimidine derivatives at a concentration of 10-6 M contributed to the growth and development of shoots and roots compared to control wheat plants treated with distilled water. The regulatory effect of thioxopyrimidine derivatives on the vegetative growth of wheat plants was similar to the regulatory effect of auxin IAA (1H-indol-3-yl)acetic acid) or synthetic compounds, derivatives of sodium and potassium salts of 6-methyl-2-mercapto-4-hydroxypyrimidine (Methyur, Kamethur) and N-oxide-2,6-dimethylpyridine (Ivin) used in the same concentration of 10-6 M. The correlation between the growth regulatory effect and the chemical structure of synthetic compounds, thioxopyrimidine derivatives was established. The selected most active synthetic compounds, thioxopyrimidine derivatives, are proposed to be used to improve the vegetative growth of wheat (T. aestivum L.) variety Oksamit Mironivskyi. KEYWORDS: Triticum aestivum L., Thioxopyrimidine derivatives, IAA, Methyur, Kamethur, Ivin
Despite Bharat's rich and diverse linguistic traditions, modern linguistics was introduced here as a colonial discipline. Three colonial narratives introduced modern linguistics in Bharat by the British orientalists Sir William Jones (1786 [1787]), Francis Whyte Ellis (1816) and Robert Caldwell (1856). Even after decades of independence, linguistics continues as a colonial discipline in Bharat. This lecture attempts to review colonial linguistics practices in Bharat and proposes areal linguistics as an alternate paradigm. In the first part, the decolonization of linguistics in Bharat is defined. In the second part, we will critically examine the colonial content of three narratives. The third part will discuss the Bharatiya potential of contact and convergence linguistics. Certain proposals are presented for the advancement of areal linguistics in Bharat. Further, how areal linguistics can decolonize linguistics in Bharat is discussed in the concluding part. In short, the contact and convergence study of languages in Bharat is proposed as the Bharatiya model of linguistics to describe and explain the convergence and divergence of languages in Bharat.

A laser radar system has been constructed. It is based on a commercial PC with digitizer, pulse delay instrument, National Instruments IO card and an optical head from a previous laser radar program. The laser radar was mounted on a gyro stabilized gimbal on the nose of a helicopter and flown in the Mojave Desert in September 2006. The collected data will be used to test algorithms for future precision lunar landers, which may be utilizing a laser radar as the primary landing sensor. This paper will describe the laser radar and PC based acquisition system used for the data collection, and provide an overview of the supporting test sensors and architecture. Preliminary data collected during the helicopter field testing will also be presented.
