  • A processing department is an organizational unit where work is performed on a prod- uct and where materials, labor, or overhead costs are added to the product. For example, a Nalley’s potato chip factory might have three processing departments—one for preparing potatoes, one for cooking, and one for inspecting and packaging. A brick factory might have two processing departments—one for mixing and molding clay into brick form and one for firing the molded brick. Some products and services may go through a number of processing departments, while others may...

  • Natural variations in pH and oxygen status are also important and are not restricted to deep environments. Many groundwaters in tropical regions in weathered basement aquifers and alluvial sequences have low pH, and the reducing conditions which prevail can promote the mobilisation of metals and other parameters of health significance such as arsenic.

  • More important, this abstraction separates different Organizations from each other. Even if they happen to be assigned common networks, datastores, or resource pools, they cannot modify or even see each other’s vApps without explicitly sharing them. (The exception is vApps connected to the same External Network, as they’re sharing the same vSwitch.) Providing Organizations with unique datastores, networks, and resource pools enforces even greater separation between the Organizations through the quotas you can set in those abstractions.

  • Collection of similar entities or concepts into a higher level concept. EMPLOYEE class collects all employees into one class A class has properties called “class properties”. EMPLOYEE class has class properties - e.g., average salary, total number of employees. Each member has values for own properties (e.g. name, address, salary): called member properties.

  • Abstract Amulti-attribute group decisionmakingmethod composed of intuitionistic fuzzy set and TOPSIS will be introduced into project material bidding procurement. First, the opinions of experts about bidders and indicators’ attributes are expressed by linguistic terms, and then turned into intuitionistic fuzzy numbers, which can be used to obtain the weights of the indicators’ attributes and experts. Based on the opinions of decision makers and IFWA operators, an aggregated intuitionistic fuzzy decision matrix is formulated. In the end, the bidders are ranked by TOPSIS method....

  • Computational Grids [1, 2] are large collections of resources such as computers, networks, on-line instruments, or storage archives, and they are becoming popular platforms for running large-scale, resource-intensive applications. Many challenges exist in providing the necessary mechanisms for accessing, discovering, monitoring, and aggregating Grid resources. Consequently, a tremendous effort has been made to develop middleware technology to establish a Grid software infrastructure (GSI) [2–4].

Nanoscale Research Letters 2011, 6:248 http://www.nanoscalereslett.com/content/6/1/248 NANO EXPRESS Open Access Viscosity affected by nanoparticle aggregation in Al2O3-water nanofluids Fei Duan*, Dingtian Kwek, Alexandru Crivoi Abstract An investigation on viscosity was conducted 2 weeks after the Al2O3-water nanofluids having dispersants were prepared at the volume concentration of 1-5%. The shear stress was observed with a non-Newtonian behavior. On further ultrasonic agitation treatment, the nanofluids resumed as a Newtonian fluids.

  • At the present day no clear and consistent opinion seems to be held regarding Classical Philology. We are conscious of this in the circles of the learned just as much as among the followers of that science itself. The cause of this lies in its many-sided character, in the lack of an abstract unity, and in the inorganic aggregation of heterogeneous scientific activities which are connected with one another only by the name "Philology.
