Barley fields reach 1.7 million hectares in Spain, of which 320,000 are used to produce malt, generating 450,000 tons crop residue from barley intended for malt production. One way treat this waste an environmentally sound, energy-sustainable and economically cost-effective manner is anaerobic digestion. The biogas generated can be as fuel a renewable source energy (providing solution the suppl...

Coming out from the growth kinetics, the Gompertz model has been developed and considered as the best one for simulating the biogas production from anaerobic digestion. However, the model has failed to describe the starting point of the process, and no-sense of lag phase constant has been pointed out. Thus, the goal of this study is to develop a new kinetic model of biogas production with meani...

We present first results of an experiment to combine data from Keck aperture masking and the Infrared-Optical Telescope Array (IOTA) to image the circumstellar environments of evolved stars with ∼20 milliarcsecond resolution. The unique combination of excellent Fourier coverage at short baselines and highquality long-baseline fringe data allows us to determine the location and clumpiness of the...

The recent widespread application of whole-genome sequencing (WGS) for microbial disease investigations has spurred the development of new bioinformatics tools, including a notable proliferation of phylogenomics pipelines designed for infectious disease surveillance and outbreak investigation. Transitioning the use of WGS data out of the research laboratory and into the front lines of surveilla...

We have established a compact and transportable I2-stabilized Nd:YAG laser for international comparisons of laser frequency. The root Allan variance of the portable laser has reached 3 9 10 14 when the integration time is longer than 200 s. The results of an international comparison between the National Research Laboratory of Metrology (NRLM), Tsukuba, Japan and the JILA (formerly the Joint Ins...

To assess the diagnostic accuracy of margin evaluation of melanocytic lesions using en face frozen sections compared with standard paraffin-embedded sections, we studied 2 sets of lesions in which en face frozen sections were used for analysis of surgical margins (13 from malignant melanomas [MMs] and 10 from nonmelanocytic lesions [NMLs]). Routine permanent sections were cut after routine proc...

Large robotics projects can no longer be done by a single person writing a monolithic piece of code. Projects are now composed of modules which can be libraries, threads of execution, or stand-alone processes. Di erent people will almost certainly work on di erent modules, with the module developers sometimes being geographically distant from each other. Thus, good interprocess communications t...

STUDY DESIGN Prospective, multicenter, international observational study. OBJECTIVE To evaluate motor neurologic outcomes in patients undergoing surgery for complex adult spinal deformity (ASD). SUMMARY OF BACKGROUND DATA The neurologic outcomes after surgical correction for ASD have been reported with significant variability and have not been measured as a primary endpoint in any prospecti...

We show that the normalized maximum likelihood (NML) distribution as a universal code for a parametric class of models is closest to the negative logarithm of the maximized likelihood in the mean code length distance, where the mean is taken with respect to the worst case model inside or outside the parametric class. We strengthen this result by showing that the same minmax bound results even w...
