Skip furrow irrigation (SFI) can save water by irrigating every alternate furrow. Usually, irrigated furrows are alternated at each event under SFI. If fixed (permanent SFI, PSFI), more may be saved reducing the wetting area, and salts accumulate on dry side of ridge. Salt removal sheet, a method collecting sheet laid soil surface utilizing high evaporation demand in drylands, an efficient meas...

A new site-specific endonuclease, Sfi I, has been isolated from Streptomyces fimbriatus . This is the first report of a type II restriction endonuclease whose recognition specificity requires eight nucleotides. Sfi I cleaves the sequence, GGCCNNNN / NGGCC , symmetrically to produce a three base, 3' extension.

SFI Working Papers contain accounts of scientific work of the author(s) and do not necessarily represent the views of the Santa Fe Institute. We accept papers intended for publication in peer-reviewed journals or proceedings volumes, but not papers that have already appeared in print. Except for papers by our external faculty, papers must be based on work done at SFI, inspired by an invited vis...

BACKGROUND Sporadic fatal insomnia (sFI) and fatal familial insomnia (FFI) are rare human prion diseases. CASE PRESENTATION We report a case of a 33-year-old female who died of a prion disease for whom the diagnosis of sFI or FFI was not considered clinically. Following death of this patient, an interview with a close family member indicated the patient's illness included a major change in he...

BACKGROUND AND PURPOSE Shenfu injection (SFI), derived from the ancient traditional Chinese medicine (Red Radix Ginseng and Radix Aconitum Carmichaeli), has been widely used in the clinical for the treatment of cardiovascular diseases for more than 20 years. The present study aims to investigate the effects of SFI and its main components on the contraction of isolated rat thoracic aorta rings a...

Refinement calculus [1,5] is a formal framework for reasoning about program correctness and correctness preserving program refinements. It serves as the foundation for an object-oriented software architecture and construction method that we refer to as stepwise feature introduction (SFI) [3]. Characteristic for this approach is that each software module is described in terms of thin layers. Eac...

Recent improvement in technologies for measuring individual feed intake has made possible the collection of data suitable for breed-wide genetic evaluation. The goals of this research were to estimate genetic parameters for components of feed efficiency and develop a prototype system for conducting a genetic evaluation of Angus cattle for feed intake. Weaning weight (WWT), postweaning BW gain (...

BACKGROUND The Spine Functional Index (SFI) is a recently published, robust and clinimetrically valid patient reported outcome measure. OBJECTIVES The purpose of this study was the adaptation and validation of a Spanish-version (SFI-Sp) with cultural and linguistic equivalence. METHODS A two stage observational study was conducted. The SFI was cross-culturally adapted to Spanish through dou...
