Seeding has been critical for obtaining diffraction-quality crystals for many structures. In this article, applications and recommendations for seeding are presented based on examples from our laboratory and other groups. The implementation of seeding in high-throughput crystallization, robotics, and other emerging technologies is also discussed.

Several agronomic benefits can result from fall seeding of canola (Brassica spp.), but extensive research data are lacking on the potential impact of this practice on infestations of root maggots (Delia spp.) (Diptera: Anthomyiidae), which are major pests of the crop in western Canada. Field experiments making up 13 location by year combinations were conducted in central Alberta, Canada, from 1...

In order to improve the quality of corn sowing and fertilizer utilization, reduce labor costs, this paper aimed at traditional tillage machine improve. The seeding fertilizing with adjustable flow is designed by integrating particle sensor CAN bus transmission technology. It mainly composed seed discharging mechanism, ditch soil covering leakage blockage monitoring system. Fertilizer drop signa...

Information spreading in complex networks is often modeled as disseminating information with certain probability from nodes that possess it to their neighbors that do not. Information cascades are triggered when the activation of a set of initial nodes – seeds – results in diffusion to large number of nodes. Here, several novel approaches replacing the commonly used strategy of initiating all s...

Despite significant progress in our understanding and treatment of metastatic cancer, nearly all metastatic cancers are incurable. In this Review, we use breast cancer as a model to highlight the limitations and inconsistencies of our existing treatment paradigms for metastatic disease. In turn, we offer a new theory of metastasis, termed "self-seeding. " The self-seeding paradigm, well validat...

and nonpalpable breast lesions is a safe and effective alternative to fine-needle aspiration and needle-localized breast excisional biopsies (1, 2). It can reduce the need for a two-stage procedure and can improve the surgical and oncological outcomes (3). However, one disadvantage of this technique for sampling breast cancer is the possible seeding of malignant tumor cells along the needle tra...

The Provincial Government of Mendoza (Argentina), had protected the local crops from the hail damage during five seasons (1999-2004) by contracting an operational service. These operations consisted in silver iodide seeding (AgI) methodology by means of several aircrafts. The aircrafts were provided with meteorological instruments and probes, which allowed obtaining an important amount of data ...

We demonstrate the ability to generate ultra-high-frequency sequences of broadly wavelength-tunable, high-intensity laser pulses using a custom-built optical parametric oscillator pumped by the third-harmonic output of a "burst-mode" Nd:YAG laser. Burst sequences consisting of 6-10 pulses separated in time by 6-10 mus are obtained, with average total conversion efficiency from the 355 nm pump t...

OBJECT Chordomas have a high propensity for local recurrence and progression, as well as for systemic and cerebrospinal fluid metastasis. The authors identified and analyzed a series of patients with chordomas, focusing on an underrecognized entity--surgical seeding. METHODS In a retrospective analysis of 82 patients with chordomas treated over a 10-year period (1990-2000) the authors found s...

To identify, through a systematic literature review, the characteristics of neoplasm seeding in biopsy performed on the musculoskeletal system. We performed a search on PubMed, MEDLINE, LILACS and SciELO from August to October 2010. We included articles that addressed the neoplasm seeding in biopsy performed on the musculoskeletal system. The search was limited to English, Spanish and Portugues...
