Speech compredon is widely used in tel-dons, espedally in cellular telephony and voice over packet networks. Traditional network speech enhancement techniques, which operate on mded speech, q u i r e that the compresed speechbe demded. After perForming echo caudation and noise dudion, the speed^ is recylooded for M e r transport Due to the need for reencoding the speech, Such proceaing is coqutalionally iuhlsivq and gpeciany prone to additional quantization wise FurthermDre, additional delay is incurred. In this paper, a dim3 compresed domain signal p q approarh to speech enhancemnt is intt.oduced. Me4hods for mplmenting acoustic echo control and noise d u d i o n are discussed. The compmsed domain approach is athadive due to lpduced computational oasts, delay and quantization noise.

A field study conducted to evaluate the efficacy of new molecules against okra shoot and fruit borer, Earias vitella (Fb.) during rabi and summer season revealed that Chlorantraniliprole 8.8% + Thiamethoxam17.5% SC @ 0.7 ml/l significantly reduced the percentage of shoot and fruit damage. No shoot and fruit infestation was recorded at seven and fourteen days after treatment. It was on par with the standard check Chlorantraniliprole 18.5 SC @ 0.3 ml/l followed by Novaluron 10 EC @ 2 ml/l and Lamdacyhalothrin 4.6% + Chlorantraniliprole 9.3% ZC. Chlorantraniliprole 8.8% + Thiamethoxam17.5% SC treated plots recorded highest total yield of 469.86 and 594.31 g/plant respectively. Maximum marketable yield was also recorded from Chlorantraniliprole 8.8% + Thiamethoxam17.5% SC treated plots respectively. Chlorantraniliprole 8.8% + Thiamethoxam17.5% SC also showed high benefit-cost ratio of 2.42 and 3.12 during rabi and summer season respectively.
