Enforcing dynamic access control constraints in workflow management systems (WFMS) is a very important requirement with regard to security issues. However, respecting those constraints may prohibit the completion of a workflow instance in the case of the lack of authorized users. Such situation is known in the literature as a WSP (Workflow Satisfiability Problem). The ability of a WFMS to use d...

We describe the isolation and characterization of nwk (nervous wreck), a temperature-sensitive paralytic mutant that causes excessive growth of larval neuromuscular junctions (NMJs), resulting in increased synaptic bouton number and branch formation. Ultrastructurally, mutant boutons have reduced size and fewer active zones, associated with a reduction in synaptic transmission. nwk encodes an F...

Background. The grain coat plays a major role in the development of rye cultivars with low levels water-soluble pentosans (WSP). Grain thinness is diagnostic trait for WSP (arabinoxylans) content. To improve technology low-pentosan breeding, it becomes important to study effect changes anatomy grains on morphological characteristics. Materials and methods. Grains thin coats (transparent) were i...

Polyvinyl ester green composites were synthesized with walnut shell powder (WSP) by in-situ polymerization technique. The green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. Sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...

Ground-elutter breakthrough caused by anomalous propagation (AP}----ducting of the radar beam when passing through significant atmospheric temperature and/or moisture gradients-is a significant issue for air traffic controllers who use Airport Surveillance Radar (ASR) weather channel data to guide aircraft through the airport terminal area. At present, these data are often contaminated with AP,...

Low-level wind shear, especially a microburst, is very hazardous to aircraft departing or approaching an airport. The danger became especially clear in a series of fatal commercial airliner accidents in the 1970s and 1980s at U.S. airports. In response, the Federal Aviation Agency (FAA) developed and deployed three ground-based lowaltitude wind-shear detection systems: the Low Altitude Wind She...

Web services bring programmers a new way to develop advanced applications able to integrate any group of services on the Internet into a single solution. Web services procurement (WSP) is focussed on the acquisition of web services, including some complex tasks such as the specification of demands, the search for available offers, and the best choice selection. Although the technology to suppor...

Gastrointestinal (GI) mimic and organic solvent extracts of whole soybean powder (WSP), soy protein concentrate (SPC), and soy protein isolate (SPI) as well as soy isoflavone concentrate (SIC) were analyzed for total phenols; quinone reductase (QR) induction in hepa1c1c7 cells; antioxidant scavenging of DPPH, HOCl, ONOO(-), and O(2) (-.); and total antioxidant capacity via FRAP and ORAC assays....
