In a device for transporting liquid, liquid to be transported is enclosed by an oil droplet, which is fractionated with air, for manipulation. Moreover, as a method for supplying liquids wherein a plurality of liquids are enclosed by an oil droplet sequentially and treated, liquid enclosed by an oil droplet is formed by associating one oil with one liquid in a liquid introducing section. According to the present invention, even in the case where a plurality of liquids are manipulated, it is possible to manipulate stably without affecting other liquids. Moreover, it is possible to treat as a liquid enclosed by an oil droplet successively in the device for transporting liquid, thereby allowing the invention to be applied to a system for analyzing easily.

Various apparatus and associated methods involve a light source that provides light at wavelengths that substantially correlate to local maxima in the spectral sensitivity of a diurnal avian. In an illustrative example, the light source may output light primarily in wavelength bands that are not substantially absorbed by colored oil droplets and / or visual pigment in at least one type of cone in the eye of a diurnal avian. In some embodiments, the light source may include a light-emitting diode (LED) light source. Exemplary light sources may output spectral components to illuminate diurnal avians with local maxima of intensity at wavelengths that substantially correspond to local maxima in a spectral sensitivity visual response characteristic of the diurnal avians.

Using an homogenizer operating at higher pressures (ca. 2000 bar) than those conventionally used in ice cream manufacturing, it is possible to generate smaller oil droplet sizes (ca. 0.3 mum) in an ice cream premix. It allows stabilization of a larger air:water interface, leading to smaller discrete gas cells which in turn modify the organoleptic quality of the ice cream.

Fluids viscosified with viscoelastic surfactants (VESs) may have their viscosities reduced (gels broken) by the direct or indirect action of a breaker composition that contains at least one mineral oil, at least one polyalphaolefin oil, and / or at least one saturated fatty acid. The breaker may initially be dispersed oil droplets in an internal, discontinuous phase of the fluid. In one non-limiting embodiment, the breaker, e.g. mineral oil is added to the fluid after it has been substantially gelled. The breaking composition is believed to act possibly by rearranging, disaggregating or otherwise attacking the micellar structure of the VES-gelled fluid in a non-spontaneous, rate controlled manner at elevated fluid temperatures. In a specific, non-limiting instance, a brine fluid gelled with an amine oxide surfactant can have its viscosity broken with a light, low viscosity paraffinic mineral oil.

A damped steel baffle for an engine cam cover aids in separation of oil mist entrained in a flow of crankcase air vented through the cam cover, and directs the air to a PCV valve atop the cover. The baffle forms a channel for the air, and effectively absorbs noise generated within the cover. Oil droplets condense on channel and baffle surfaces, and drain to an engine oil sump. The interface between baffle and cam cover is sealed with a foam gasket layer or RTV sealant. The baffle is constructed of two metal layers joined together by a thin layer of viscoelastic adhesive that converts vibrational energy into heat to dampen resonant vibrations. Amplitudes of vibration are significantly lower than for plain steel baffles, hence lower sound radiation is achieved. The individual steel layers are 0.2 to 0.6 mm thick; the viscoelastic layer has a thickness up to 0.15 mm.

A process for removing hydrocarbons such as oil from produced water entrains high concentrations of very small gas bubbles within produced water inside a vertically-oriented primary separation tank by means of aerators immersed in the water inside the tank. Oil droplets coat the gas bubbles which form a buoyant oil-rich froth phase overlying a gas-rich liquid phase. The froth phase flows out through a discharge port in a preferably conical upper section of the primary tank, for disposal or recovery of oil as appropriate. Solid contaminants not borne by the froth phase may be intermittently settled out of the liquid phase and removed for treatment or disposal through a discharge port in a preferably conical lower section of the primary tank. Clean processed water is drawn a medial region of the primary tank for re-use as appropriate. In a preferred embodiment, the froth phase passes into a secondary separation tank for further separation of contaminants by means of gravity and / or supplemental aeration.

A short tandem repeat (STR) typing method and system are developed for forensic identification of individual cells. Agarose-in-oil droplets are produced with a high frequency using a microfluidic droplet generator. Statistically dilute single cells, along with primer-functionalized microbeads, are randomly compartmentalized in the droplets. Massively parallel single-cell droplet PCR is performed to transfer replicas of desired STR targets from the single-cell genomic DNA onto a coencapsulated microbead. These DNA-conjugated beads are subsequently harvested and reamplified under statistically dilute conditions for conventional capillary electrophoresis STR fragment size analysis. The methods and systems described herein are valuable for the STR analysis of samples containing mixtures of cells / DNA from multiple contributors and for low concentration samples.
