Синтез и инсектицидная активность новых 1,2-диацил-1-алкилгидразинов, содержащих фрагменты 3,5-диметил- и галогенбензойных кислот

New 1,2-diacyl-1-alkylhydrazines containing fragments of halogenated benzoic acids and 3,5-dimethylbenzoic acid have been synthesized. These compounds are close structural analogues of known ecdysteroid agonists, methoxyfenozide and halofenozide, used in agriculture as hormonal biorational insecticides. Primary screening of new organic compounds for insecticidal activity has been performed. It has been discovered that two of the synthesized compounds are more toxic for Colorado potato beetle than methoxyfenozide.Разработаны методы синтеза новых 1,2-диацил-1-алкилгидразинов - близких структурных аналогов известных экдистероидных агонистов галофенозида и метоксифенозида, используемых в сельском хозяйстве в качестве биорациональных инсектицидов гормонального действия. Характерной особенностью строения целевых соединений является наличие 3,5-диметилбензоильной группировки при N-1 и галогенбензоильных остатков при N-2 трет- бутилгидразинового фрагмента. Обнаружено, что два из синтезированных веществ по токсичности для колорадского жука превосходят известный экдистероидный агонист метоксифенозид

Синтез и инсектицидная активность новых 1,2-диацил-1-алкилгидразинов, содержащих фрагменты метил- и метоксибензойных кислот

The methods for synthesis of new 1,2-diacyl-1-alkylhydrazines, close structural analogues of a known ecdysteroid agonist, methoxyfenozide, containing tert-butyl group at N-1 of the hydrazine moiety and 3,5-dimethyl benzoic acid fragment (as in the methoxyfenozide molecule) have been developed. The insecticidal activity of compounds prepared have been studied on the Colorado potato beetle larvae of second age. Among the synthesized compounds, sufficiently active insecticides have been found, that are promising for further study in order to clarify their possible use as active ingredients in modern formulations of biorational pesticides.Разработаны методы синтеза новых 1,2-диацил-1-алкилгидразинов - близких структурных аналогов известного экдистероидного агониста метоксифенозида, используемого в сельском хозяйстве в качестве биорационального инсектицида гормонального действия. Синтезированные соединения имеют при N-1 гидразинового фрагмента трет-бутильную группу и, как правило, остаток 3,5-диметилбензойной кислоты. При N-2 в целевых соединениях содержатся главным образом остатки разнообразных метил- и метоксибензойных кислот. Обнаружено, что два из синтезированных веществ по токсичности для колорадского жука превосходятметоксифенозид

CP Studies and Non-Standard Higgs Physics

There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce new sources of CP violation, and there may be mixing between multiple Higgs bosons or other new scalar bosons. Alternatively, the Higgs may be a composite state, or there may even be no Higgs at all. These non-standard Higgs scenarios have important implications for collider physics as well as for cosmology, and understanding their phenomenology is essential for a full comprehension of electroweak symmetry breaking. This report discusses the most relevant theories which go beyond the Standard Model and its minimal, CP-conserving supersymmetric extension: two-Higgs-doublet models and minimal supersymmetric models with CP violation, supersymmetric models with an extra singlet, models with extra gauge groups or Higgs triplets, Little Higgs models, models in extra dimensions, and models with technicolour or other new strong dynamics. For each of these scenarios, this report presents an introduction to the phenomenology, followed by contributions on more detailed theoretical aspects and studies of possible experimental signatures at the LHC and other colliders.Comment: Report of the CPNSH workshop, May 2004 - Dec 2005, 542 pages.

Pre-master programs for foreign citizens

This paper considers actuality, scientific and methodological principles of the Pre-Master program design for foreign citizens, as well as educational technology for its realization. According to the analysis of the experience realization of the Pre-Bachelor and Pre-Master programs for foreign citizens in foreign and Russian universities, the differences betweenthese programs and the specific features of the Pre-Master programs are shown. The results of the initial monitoring of the Pre-Master program realization in Tomsk Polytechnic University are analyzed and proposals for its further development are presented
