The principal objective of this study was to determine the optimal liquid culture conditions in shake flasks for maximal sporulation of Beauveria bassiana. The optimal initial pH for the spore production of B. bassiana using Potato Dextrose Broth was 5.2. The screening in shake flasks of carbon and nitrogen sources resulted in the identification of an(More)
INTRODUCTION Improving patient identification (ID), by using two identifiers, is a Joint Commission safety goal. Appropriate identifiers include name, date of birth (DOB), or medical record number (MRN). OBJECTIVES The objectives were to determine the frequency of verifying patient ID during computerized provider order entry (CPOE). METHODS This was a(More)
Spores of Aspergillus sp. SU14 were treated repeatedly and sequentially with Co(60) γ-rays, ultraviolet irradiation, and N-methyl-N'-nitro-N-nitrosoguanidine. One selected mutant strain, Aspergillus sp. SU14-M15, produced cellulase in a yield 2.2-fold exceeding that of the wild type. Optimal conditions for the production of cellulase by the mutant fungal(More)
Texture features extraction algorithms are key functions in various image processing applications such as medical images, remote sensing, and content-based image retrieval. The most common way to extract texture features is the use of Gray Level Co-occurrence Matrices (GLCMs). The GLCM contains the second-order statistical information of spatial(More)
A fungal strain producing a high level of cellulase was selected from 320 fungal isolates and identified as Aspergillus sp. This strain was further improved for cellulase production by sequential treatments by two repeated rounds of γ-irradiation of Co(60), ultraviolet treatment and four repeated rounds of treatment with(More)
Business process modeling has become a popular method for improving organizational efficiency and quality. Automatic validation of process models is one of the most valuable features of modeling tools, in face of the increasing complexity of enterprise business processes and the richness of modeling languages. This paper proposes a formal language,(More)
The semantic geometric crossover (SGX) proposed by Moraglio et al. has achieved very promising results and received great attention from researchers, but has a significant disadvantage in the exponential growth in size of the solutions. We propose a crossover operator named subtree semantic geometric crossover (SSGX), with the aim of addressing this issue.(More)
The early detection of flaws and errors has become a significant feature of a business process modeling tool. This paper proposes an ontology-based approach for business process compliance checking. The business processes and the business rules are represented in a machine understandable form, a reasoner is used to reason on this knowledge base for(More)
Motivation – The complex nature of health care processes requires new methods for describing, capturing and improving these processes. Research approach – We deployed a novel combination of methods-formal process modeling using a language called Little-JIL, simulations with embedded errors, observations, and eye tracking technology-to gauge how health care(More)
