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...

A 58-year-old female presented with renal colic and was found to have renal transitional cell carcinoma at the time of percutaneous surgery. She developed percutaneous tract seeding that clinically presented as subcutaneous skin nodules. After local treatment with surgical excision and radiation treatment, the patient developed retroperitoneal recurrence 5 years later. Percutaneous tract seedin...

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...

Operational cloud seeding programs have been increasingly deployed in several countries to augment natural rainfall amounts, particularly over water-scarce and arid regions. However, evaluating operational by quantifying impacts remains a challenging task subject complex uncertainties. In this study, we investigate using both long-term rain gauge records event-based weather radar retrievals wit...

Rangelands are the main source of forage production whose degradation is being accelerated due to improper utilities. Furthermore, re-vegetation of palatable plants like Vicia variabilis is more limited in overgrazed rangelands. The objective of this study was to improve degraded rangelands in Meleh-Kabud (Kermanshah, Iran) through planting Vicia variabilis. The research was conducted at experi...

In Genetic Algorithm (GA), the fitness or quality of individual solutions in the initial population plays a significant part in determining the final optimal solution. The traditional GA with random population seeding technique is simple and proficient however the generated population may contain poor fitness individuals, which take long time to converge to the optimal solution. On the other ha...

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...
