An analytical toilet comprising: a bowl for collecting feces from a user; a comminutor that comminutes at least a portion of the feces; a processing fluid driver that causes a processing fluid to mix with and transport at least a portion of the comminuted feces to an analytical station in the toilet; a separator that separates a sample of the at least a portion of the comminuted feces to be analyzed; and a wash fluid driver that causes a wash fluid to wash the feces out of the bowl.

In a process for purifying fatty acid alkyl esters, particularly methyl and ethyl esters, by means of vacuum distillation in a distillation column, water or steam is introduced into the distillation column and, during distillation, brought into contact with the fatty acid alkyl esters in the gas phase. This results in a significant reduction in the sulphur content and in the acid number of the fatty acid alkyl ester.

A gas supply device for operation in an incubator allowing treatment of a culture within a shaker flask with gas independently of the composition and humidity of the gas atmosphere within the incubator individually supplies each shaker flask of the incubator with gas using a gas supply clamp detachably connected to the closure cap of each flask. The gas supply clamp has at least two elastic clamping jaws and a web connecting the clamping jaws to one another. The clamping jaws exert a clamping force on the side wall of the closure cap. The clamp is held in place by the elastic clamping jaws. Above a sterile filter in the closure cap, an individual gas atmosphere for treatment of the culture in the shaker flask is produced in a recess of the web above a gas passage in the closure cap.

An improved method for preparing squalene from a squalene-containing composition, said method comprising the steps of (a) a purification distillation carried out at a temperature T.sub.1 (b) a denaturing distillation carried out at a temperature T.sub.2; wherein steps (a) and (b) may be performed in either order; T.sub.1 and T.sub.2 are sufficient to cause squalene to boil; T.sub.2>T.sub.1; and T.sub.2>200° C.

The present invention relates to methods of preparing purified cyclopropylene (1-methylcyclopropylene) gas employing one or more non-reactive purification processes to purify substances including, without limitation, cyclopropene (1-methylcyclopropylene) gas and/or lithio-cyclopropene.

A method of processing finely divided reactive particulates (R.sub.Particulate) and forming a product comprising: providing a composite material comprising finely divided reactive particulates (R.sub.Particulate) dispersed in a protective matrix; at least partially exposing the finely divided reactive particulates (R.sub.Particulate); and forming the product.

Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During block operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. This can allow for formation of unexpected base stock compositions.
