ballast for the single-lane, low-volume forest roads known as branches and spurs. 1 When road builders weigh the cost of producing and applying crushed aggregate against hard-to-quantify benefits such as improved road and vehicle maintenance costs and reduced log truck cycle times, it can be difficult to justify crushing. There are spe cific

The spread of aquatic invasive species through ballast water is a major ecological and economical threat. Because of this, the International Maritime Organization (IMO) set limits to the concentrations of organisms allowed in ballast water. To meet these limits, ballast water treatment systems (BWTSs) were developed.

Plant Capacity – For low-capacity facilities, producing up to 5,000 tons per year of formalin, the silver process is more economical. This process is less technical and requires fewer upfront costs, making it an attractive option for smaller operations. Larger plants producing up to 100,000 tons per year, however, likely should use the iron ...

T5 fluorescent tubes are not considered to be full-spectrum lighting. Fluorescent lighting is known for producing a broad spectrum of light, but it does not produce all wavelengths visible to the human eye. In particular, fluorescent lighting tends to be deficient in red and far-red wavelengths, which are important for plant growth and development.
