An elongate device for dispensing a measured quantity of a paste-like resinous nutritional substance for consumption, injection, or topical use has an integral, outwardly directed hook at a first end. In one case, the elongate device is curved along its length from the hook to a second end and has a concave front face and a convex rear face, with a metered end portion on the front face or on both faces extending from the second end and having one or more scale markings for indicating an amount of paste-like substance adhered to the end portion between a scale marking and the second end. The dispensing device may alternatively be used for dissolving a measured quantity of the material in a liquid by engaging the hook over the rim of a container to suspend the device into the container with the metered end portion submerged in liquid in the container.

A microfluidic chip is disclosed. According to an embodiment, a microfluidic chip including an inlet part in which a first inlet is provided into which a first fluid is injected; a middle part in which a first flow path is provided in which the first fluid can flow, wherein on the first flow path, a raw material storage part may be provided for storing a mixed raw material which can be mixed with the first fluid.

A continuous process for enhanced oil recovery (EOR) to be used in heavy and extra heavy oil wells, where low and/or non-profitable production rates occur is presented. The process is named Hot Crude Gravity Drainage (HCGD), and HCGD may include different components to support the heating of crude produced in the oil well that is later going to be injected at the same volumes as heated crude. The crude may be injected in the sand from which it was produced, in order to continuously supply the required energy to significantly lower the viscosity, which in turn increases mobility in the pores of the producing sand and allows for an increment (e.g., of more than 100%) in production as regards the base or initial production of the oil well, in a 45 consecutive day period. The process unit may be simple, compact, modular and skid mounted.

Provided is a mixing system to mix different types of fluids more efficiently. The mixing system installed in a piping in which a first fluid is supplied includes a mixing part including a plurality of mixing members each having a front end and a rear end rotated by a predetermined angle to form a curved surface and disposed to be spaced apart from each other and a supply part supplying a second fluid to a space between adjacent mixing members.
