Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. In search of efficient PGPR strains with multiple activities, a total of 150 bacterial isolates belonging to Bacillus, Pseudomonas, Azotobacter and Rhizobium were isolated from different rhizospheric soil of chick pea in the vicinity of Allahabad. These test isolates were bi...

An optimal scheduling approach has been developed for coordinating product delivery activities using fuzzy mathematics. In this approach, optimal delivery scheduling is carried out at three different levels, for situations involving: (1) one driver and one load, (2) one driver and multiple loads, and (3) multiple drivers and multiple loads. Fuzzy-based clustering methods are employed to classif...

This paper presents three-dimensional tongue surfaces reconstructed from multiple coronal cross-sectional slices of the tongue. Surfaces were reconstructed for sustained vocalizations of the American English sounds [symbol: see text]. Electropalatography (EPG) data were also collected for the sounds to compare tongue surface shapes with tongue-palate contact patterns. The study was interested a...

NASA’s Mars Exploration Rovers have set the standard for autonomous robotic exploration of planetary surfaces. Their abilities to detect and avoid geometric hazards, and measure and compensate for slip or heading changes, have made it possible to drive farther and in highly sloped areas, increasing the science return of the mission. Software updates that took place during the more than three ye...

This study investigated the effects of corrective feedback (CF) on the acquisition of English prepositions to find out which one would be more effective for third-grade high school learners in their grammar performance. This study also examined declarative and interrogative recasts to see which one the participants preferred to improve their grammar performance. To this end,75 out of 130 female...

in this paper, we consider locally graded groups in which every non-permutable subgroup is soluble of bounded derived length.
