Across prehistoric Europe several techniques were used to produce salt, including solar evaporation and the briquetage method. Here, authors focus on a third technique in Romania western Ukraine. Building excavations at Băile Figa series of wooden troughs found there, conduct experiments elucidate how these objects may have been salt production: drip water onto rock surfaces break them up; or f...

Field trials of the dilution technique for measuring snow liquid water content show that the refined procedure is rapid and simple. Measurements of the liquid water mass fraction with an absolute error of --• 1.5% can be obtained by one operator at a rate of 10-15 samples per hour, but if the water content is low (0-2%), the relative error can be high. Electrolytic conductivity is the preferred...

A simplified procedure is described for the determination of inorganic phosphate in body fluids. The method employs two stable reagents and requires a minimum number of steps. Serum is deproteinized with trichioroacetic acid containing ferrous ion and thiourea. The supernatant is decanted and mixed with a small volume of molybdic acid. The phosphomolybdate formed is immediately reduced in situ ...

Since 1997, over 50,000 homes have been demolished to allow for the “renewal” of council estates in London. This has involved “decanting” short and long-term tenants, as well those leaseholders who bought their under “right buy” legislation. Often described “social cleansing”, racialized dimensions these displacements remain under-explored despite asizable literature documenting connections bet...

I describe a new method for the separation and counting of bound and free activity in radioimmunoassays. Particles containing a radiation-absorbing (attenuating) material are added to the assay. They shield the radiation from either the antibody-bound or the free radioligand. This obviates such manipulations conventionally involved in the separation and counting steps of radioimmunoassays as ce...

A whole world is presented in front of the eyes of a gamer. This world has shapes and colours. What do colours transmit? Is this considered in digital games? These are the main issues of this work. We are part of a culture which has been decanting meanings for ages, including those of colours. These coded meanings are shared connotations of feelings, sensations, atmosphere, thoughts, and moods....

Hyaluronic acid gel is a commonly used skin/soft tissue filler in cosmetic dermatology. Hyaluronic acid fillers are packaged in proprietary luer-lock syringes that can be injected via a 30-gauge, 27-gauge or larger diameter needle depending on the consistency of the gel. A method of decanting proprietary hyaluronic acid fillers into multiple 31-gauge insulin syringes for injection is described....

Mechanical separation of liquid animal manure can be an effective technique for production of a liquid and a nutrient-rich solid fraction. The efficiency of separators depends on the physical and chemical composition of the animal manure. Therefore, the particle size composition was measured for different types of manure before treatment with a decanting centrifuge and a screw press. Storage of...
