We study the identity-based solution of Witten’s cubic bosonic open string field theory constructed by Takahashi and Tanimoto, which is claimed to describe the tachyon vacuum. We argue that the observables of the solution coincide with those of the tachyon vacuum using the method proposed by Kishimoto and Takahashi. We also discuss how to treat the kinetic term of the string field theory expand...

The main insect pests vary in different geographical areas. Studies have shown that the pomegranate biocenosis is dominated by such as Euzophera punicaella Mooze, Aphis punicae Theob, Pseudococcus komstoci Kuw, common spider (Tetranychus urticae Koch) damage was detected. Pomegranate juice gives 10-12 generations of pomegranates a year. These mainly orchards Tashkent region.

in several parts of the world, important yield losses are caused to faba bean due to attack by the black bean aphid aphis fabae scopoli. although resistance could be a good alternative to chemical control, its genetic basis is still largely unknown; and its phenotypic expression is still poorly described, making crucial the permanent evaluation of genetic resources available in different countr...

Aphids are serious pests of a wide range agricultural crops, including pomegranates and grapevines. In addition, due to the negative environmental impacts chemical insecticides, these developing important resistance against aphicides. Therefore, one alternative method control aphids is use essential oils (EO). The present study aimed evaluate insecticidal activity Citrus aurantium C. reticulata...

Plant-parasitic nematodes (PPNs) are important pests that cause an estimated ten billion dollars of crop loss each year in the United States and over 100 globally. The Animal Plant Health Inspection Service (APHIS) within U.S. Department Agriculture maintains updates Regulated Pest list. Currently, number PPNs regulated by APHIS includes more than 60 different species. This review focuses on to...
