The entomopathogenic Beauveria bassiana is a potential biopesticide. Fungicide-tolerant isolates of this fungus would have an added advantage of being compatible with the conventional chemical methods of pest control. Therefore, 30 isolates of the fungus were screened for tolerance to bavistin a commonly used benzimidazole fungicide containing methyl(More)
In non-irrigated agricultural fields in tropical zones, high temperature and water stress prevail during the main cropping season. Natural epizootics of Beauveria bassiana on lepidopteran pests occur during winter. Application of B. bassiana during hot months when pest populations are at their climax may prove an effective management strategy. Therefore, 29(More)
Direct differentiation of shoot buds in Coffea dewevrei was evident from the seedling shoots with collar region and also from collar region end of hypocotyl segments in presence of 40 μM AgNO3, 8.88 μM of BA and 2.85 μM of IAA. Apart from this, shoot end of hypocotyl explants mainly supported yellow friable callus or somatic embryos. Subsequent transfer to(More)
In Long term evaluation (LTE) systems advanced wireless communication technique is used to minimize the Multiple Access Interference (MAI). Both transmitter and receiver are responsible for the better throughput and minimum error rate. Transmitter plays the major role and needs little efficient modification in terms of transmission power and modulation(More)
The use of biopesticides compatible with chemical pesticides is recommended in pest management as an effective and ecologically sound strategy. The entomopathogenic fungus Beauveria bassiana (Balsamo) Vuill, which is used as a biopesticide, was found to exhibit and lose tolerance to two organophosphorus insecticides widely used in Indian fields. The pattern(More)
Cognitive radio is a paradigm for wireless communication, in which either a network or a wireless node changes its transmission or reception parameters to communicate efficiently avoiding interference with licensed or unlicensed users. The OFDM based cognitive radio system is used for detection of signals. But in OFDM systems the performance of the signal(More)
The end-to-end nature of Internet congestion control is an important factor in its scalability and robustness. However, end-to-end congestion control algorithms alone are incapable of preventing the congestion collapse and unfair bandwidth allocations created by applications that are unresponsive to network congestion. To address this flaw, we propose and(More)
Cafestol (caf) and kahweol (kah) are two diterpenes uniquely associated with the unsaponified lipid fraction of coffee brew and are reported to be responsible for an increase in serum cholesterol and triglyceride levels. The plant growth regulators (PGRs) indole-3-acetic acid (IAA), N 6-benzyladenine (BA), and thidiazuron (TDZ); the plant growth-promoting(More)
