A 2-year study was conducted to characterize the intercrop movement of conver- gent lady b.etle, Hippodamia convergens Guerin-Meneville （Coleoptera： Coccinellidae） b.tween adjacent cotton and alfalfa. A dual protein-marking method was used to assess the intercrop movement of the lady b.etles in each crop. In turns field collected lady b.etles in each crop were assayed b. protein specific ELISA to quantify the movement of b.etles b.tween the crops. Results indicated that a high percentage of convergent lady b.etles caught in cotton （46% in 2008; 56% in 2009） and alfalfa （46% in 2008; 71% in 2009） contained a protein mark, thus indicating that convergent lady b.etle movement was largely b.directional b.tween the adjacent crops. Although at a much lower proportion, lady b.etles also showed unidirectional movement from cotton to alfalfa （5% in 2008 and 6% in 2009） and from alfalfa to cotton （9% in 2008 and 14% in 2009）. The season-long b.directional movement exhib.ted b. the b.etles was significantly higher in alfalfa than cotton during b.th years of the study. The total influx of lady b.etles （b.directional and unidirectional comb.ned） was significantly higher in alfalfa compared with that in cotton for b.th years. While convergent lady b.etles moved b.tween adjacent cotton and alfalfa, they were more attracted to alfalfa when cotton was not flowering and/or when alfalfa of- fered more opportunities for prey. This study offers much needed information on intercrop movement of the convergent lady b.etle that should facilitate integrated pest management decisions in cotton utilizing conservation b.ological control.

The ob.ective of this paper was to predict the residual strength of post impacted carb.n/epoxy composite laminates using an online acoustic emission （AE） monitoring and artificial neural networks （ANN）. The laminates were made from eight-layered carb.n （in woven mat form） with epoxy as the b.nding medium b. hand lay-up technique and cured at a pressure of 100 kg/cm2 under room temperature using a 30 ton capacity compression molding machine for 24 h. 21 tensile specimens （ASTM D3039 standard） were cut from the cross ply laminates. 16 specimens were sub.ected to impact load from three different heights using a Fractovis Plus drop impact tester. b.th impacted and non-impacted specimens were sub.ected to uniaxial tension under the acoustic emission monitoring using a 100 kN FIE servo hydraulic universal testing machine. The dominant AE parameters such as counts, energy, duration, rise time and amplitude are recorded during monitoring. Cumulative counts corresponding to the amplitude ranges ob.ained during the tensile testing are used to train the network. This network can b. used to predict the failure load of a similar specimen sub.ected to uniaxial tension under acoustic emission monitoring for certain percentage of the average failure load.

A theorem of Lamb.echts and stanley is used to find the rational cohomology of the complement of an emb.dding S^(4n-1)→ S^(2n)× S^m as a module and demonstrate that it is not necessarily determined b. the map induced on cohomology b. the emb.dding, nor is it a trivial extension. This demonstrates that the theorem is an improvement on the classical Lefschetz duality.
