The primary ground-based instruments used to report total column ozone (TOC) are Brewer and Dobson spectrophotometers in separate networks. These instruments make measurements of the UV irradiances, and through a well-defined process, a TOC value is produced. Inherent to the algorithm is the use of a laboratory-determined crosssection data set. We used five ozone cross-section data sets: three ...

Alcohol ethoxylates (AEs) are a class of non-ionic surfactants widely used as detergents, emulsion stabilizers, foaming agents and wetting enhancers. These properties allow large industrial application as additives in the formulation of pesticides, pharmaceuticals, paints and cosmetics, as well as in mineral separation, biotechnology etc. Although there is no known toxic effect of AEs, their co...

Turkey osteomyelitis complex (TOC) is defined by the US Food Safety Inspection Service (FSIS) to include normal-appearing processed turkey carcasses that contain lesions including green discoloration of the liver, arthritis/synovitis, soft-tissue abscesses, and osteomyelitis of the proximal tibia. The lesions are associated with many different opportunistic organisms, mainly Staphylococcus aure...

Effluents from Baker's yeast production plant contain a high percentage of color and a large amount of organic load. In the present study, Baker's yeast wastewater (BYW) is treated with the electrocoagulation (EC) process using Al electrodes. Operating parameters (pH, current density, color intensity and operating time) are optimized by response surface methodology (RSM). Quadratic models are d...

The availability of a document’s logical structure in XML retrieval allows retrieval systems to return document portions (elements) instead of whole documents. This helps searchers focusing their attention to the relevant content within a document. However, other, e.g. sibling or parent, elements of retrieved elements may also be important as they provide context to the retrieved elements. The ...

Theory of constraints (TOC) is a management philosophy that seeks to increase throughput (efficiency or performance) of the system by identifying those processes that are constraining the system bottlenecks. There have been very few profound studies of TOC in health care systems. In order to fill this gap, this study was conducted to determine how healthcare systems are utilizing components of ...

Activity-based costing (ABC) and Theory of Constraints (TOC) are popular managerial tools for evaluating product mix decisions. A challenging aspect of the product mix problem involves evaluating joint products. These products involve complex interactions among resources and products and sequential decisions concerning producing joint products and their further processing. ABC and TOC assume th...

Protective Effects of α-tocopherol on the Activity and Antioxidant Profile of Bovine Spermatozoa Subjected to Ferrous Ascorbate-Induced Oxidative Stress. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(4): 1245–1255. As spermatozoa are highly vulnerable to oxidative stress development, in ...

Sediment records from Swamp Lake (SL) in the central Sierra Nevada, California, provide evidence of climatic change on millennial and centennial timescales over the lastw20,000 years. Total organic carbon (TOC) abundancevaried in concertwith elemental and isotopic tracers of organicmatter (C/N, dCorg, d15N), biogenic silica content, total magnetic susceptibility, and sediment lithology. We inte...
