Wastewater quality indicators are laboratory test methodologies to assess suitability of wastewater for disposal, treatment or reuse. The main parameters in sewage that are measured to assess the sewage strength or quality as well as treatment options include: solids, indicators of organic matter, nitrogen, phosphorus, indicators of fecal ...
Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter.
Thermal desorption spectroscopy Temperature programmed desorption (TPD) is the method of observing desorbed molecules from a surface when the surface temperature is increased. When experiments are performed using well-defined surfaces of single-crystalline samples in a continuously pumped ultra-high vacuum (UHV) chamber, then this experimental technique is often also referred to as thermal ...
TPS report. A mock-up of a TPS report cover sheet, created for the movie Office Space. A TPS report (" test procedure specification ") is a document used by a quality assurance group or individual, particularly in software engineering, that describes the testing procedures and the testing process.
Increasingly, researchers are looking to develop blood tests that could help make Alzheimer's diagnosis faster, more accurate, and less invasive. But how far have researchers actually come with ...

Typical pulse as measured with THz-TDS. In physics, terahertz time-domain spectroscopy (THz-TDS) is a spectroscopic technique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitude and the phase of the terahertz radiation.
