background: micropatterning is becoming a powerful tool for studying cells in vitro. this method not only uses very small amount of material but also mimic the microenvironment structure present in living tissues better than flask culturing techniques. in previous studies using micropatterning of extracellular matrix proteins on glass surfaces, the rate of protein detachment from the surface wa...

Elemental sulfur (ES) fertilizers have high S content but may not be effective in the year of application due to time required oxidize. Rapid oxidation possible if ES has a large surface area contact with soil. We evaluated efficacy Sulgro 70, micronized fertilizer that is sprayed onto soil surface, eight field trials southern and central Alberta over 2 yr period. Under dry conditions Alberta, ...

Rapeseed as one the most crops is the basic needs of human feeding in order to produce oil. A field experiment was conducted to study the effects of different tillage system, seeding method and rates on yield and its components, as well as, seed oil percentage of rapeseed (Brassica napus L. cv. Hyola-401) during 2011-12 growing season at Rice Research Institute of Iran-Department of Ma...

Based on a long-term introduction study of the species native to Russian Far East region, representative collection was collected, including wide range ecological groups. On basis conducted research, peculiarities preservation individual in fund (the ability persist culture for long time, vegetative renewal, self-seeding) are revealed. It is noted that number species, addition active overgrowth...

tillage and press wheel weight play an important role in seedling emergence, crop establishment and growth. an optimal combination of tillage implements and suitable press wheel weights should increase grain yield. this study investigated the effect of tillage systems and press wheel weights on dry land wheat (triticum aestivum l.) seedling emergence and grain yields in izeh, khuzestan province...

Seed availability and leaf litter limit plant establishment in some ecosystems. To evaluate the hypothesis that these factors limit understory plant recruitment in Pinus ponderosa forests, I conducted a seeding and litter removal experiment at six thinned sites in the Fort Valley Experimental Forest, northern Arizona. Experimental seeding of four native species (Penstemon virgatus, Erigeron for...

Seeding heuristics are the most widely used strategies to speed up sequence alignment in bioinformatics. Such strategies are most successful if they are calibrated, so that the speed-versus-accuracy trade-off can be properly tuned. In the widely used case of read mapping, it has been so far impossible to predict the success rate of competing seeding strategies for lack of a theoretical framewor...

The placement or seeding of stream surfaces in 3D flow fields faces a number of challenges. These challenges include perception, occlusion, and the appropriate representation of flow characteristics. A variety of streamline seeding approaches exist, little corresponding work is presented for stream surfaces. We present a novel automatic stream surface seeding and filtering algorithm. Our approa...

F nowadays are increasingly proactive in trying to strategically capitalize on consumer networks and social interactions. In this paper, we complement an emerging body of research on the engineering of wordof-mouth effects by exploring a different angle through which firms can strategically exploit the value-generation potential of the user network. Namely, we consider how software firms should...
