A mutant strain that secretes twice as much cellulase as its parent was obtained by irradiating conidia of Trichoderma viride QM 6a with a linear accelerator.

Background Subendocardial dark-rim artifact (DRA) continues to be a major issue that limits the diagnostic performance of first pass perfusion (FPP) CMR. Non-Cartesian approaches such as radial or spiral acquisition have been proposed to minimize DRAs. Among these approaches, those that can operate without the need for breath-holding typically require a time-consuming offline image reconstructi...

background: x-ray computed tomography (ct) examinations deliver a significant amount of radiation doses to patients comparing to conventional radiography examinations. the objective of the current study was to analyze and investigate the average patient received dose from axial and spiral ct exams in a medical imaging center. material and methods: in this study, the patient imaging technique, w...

J. Lee, J. M. Pauly Electrical Engineering, Stanford University, Stanford, CA, United States Introduction Balanced SSFP is known to be very sensitive to any magnetization disturbance since all gradients are fully refocused in every TR and the phase accrual between RF pulses solely comes from offresonance precession. One of the major sources for this magnetization disturbance is eddy currents th...

Allixin, a phytoalexin isolated from garlic, was induced by irradiating fresh garlic cloves with sunlight or UV light. Induced allixin was analyzed by HPLC, and the accumulated amounts of allixin were 3.1-6.3 microg/g under experimental conditions.

Using a low power green laser, we have demonstrated a rate acceleration of ~2-fold for the hydrolysis of methyl parathion by irradiating the plasmon absorption band of Au nanoparticles capped with a Cu(bpy) catalyst.

conclusions the automatic bolus-tracking method, results in higher contrast enhancement of the aorta and spleen at the portal phase, but has no effect on liver enhancement. however, bolus tracking is associated with reduced variability for liver enhancement among different patients. results forty-eight patients (23 male, 25 female, mean age=56.4±13.5 years) were included. the contrast enhanceme...

This paper concerns the so-called cosmological constant problem. In order to solve it, we propose a toy model providing an extension of the dimensionality of spacetime, with an additional spatial dimension which is macroscopically unobservable. The toy model introduces no corrections to most predictions of the “standard” general relativity regarding, among others, the so-called “five tests of g...

This article uses an evolutionary networking perspective to develop a Spiral Model of technological evolution for web technologies. This model is grounded in archival data concerning the creation and development of web browser and web search technologies (1994-2005). The Spiral Model posits that the evolutionary process for web technologies goes through four interconnected phases: network forma...
