Systems and methods corresponding with improved wellfield management are provided. In some examples, the system may initiate a step drawdown test of well efficiency to determine a cause of a decreased discharge rate of the wellfield site. The system may alter pumping of the wellfield site based on the step drawdown test, wherein a command signal is transmitted via a SCADA system to the wellfield site.

Provided are a physical property measurement method, a physical property measurement device, and a probe that can simply measure physical properties of a surface layer portion of an object. A physical property measurement method includes a step of bringing a probe into contact with a surface layer portion of a liquid or gel-like object and maintaining a contact state, a step of measuring a height of the object rising along the probe in contact with the object, and a step of calculating viscous properties or elastic properties of the surface layer portion of the object using the measured height of the object rising along the probe.

An automated batch sampling drilling mud management system (1) includes a portable mud measurement system (10) and a communications system (120). The portable mud measurement system (10) has one or more measurement devices (14) arranged to measure at least one property and/or characteristic of drilling mud; and a pumping system (16) arranged to pump a batch sample of drilling mud from a supply of drilling mud to the one or more measurement devices. The pumping system (16) is also able to subsequently flush the batch sample of drilling mud from the one or more measurement devices (14). The communications system (120) enables bidirectional communications between the mud management system (10) and a remote location to enable transfer of data therebetween and the exertion of control from the remote location to the mud management system (10).

A gravure coater test apparatus includes a gravure roll and a backup roll which are circumscribed to each other, a motor which drives the gravure roll partially submerged in a water-based pressure-sensitive adhesive for coating, a controller which adjusts the rotational speed of the motor, a doctor blade which is selected from a plurality of types to scrape the water-based pressure-sensitive adhesive from the surface of the gravure roll being rotated, and an infrared analyzer which allows at least one of the type of the water-based pressure-sensitive adhesive corresponding to the selected doctor blade, the uniformity of the coating surface, and the amount of the coated water-based pressure-sensitive adhesive to be confirmed.

The present invention relates to a method of deriving significant factors of rheological properties, which influence folding stability for developing an adhesive with excellent folding stability, and predicting folding stability through the same. It is possible to select an adhesive with excellent folding stability by measuring initial stress and a strain recovery rate as the significant factors, and measuring predicted folding stability (predicted number of times of folding) therefrom.

This invention relates to a method of evaluating a squeegeeing property of powder for lamination shaping by stable criteria. In this method, the squeegeeing property is evaluated using at least a satellite adhesion ratio of the powder and an apparent density of the powder. The satellite adhesion ratio is the ratio of the number of particles on which satellites are adhered to the number of all particles. If the satellite adhesion ratio is equal to or less than 50%, and the apparent density is equal to or more than 3.5 g/cm.sup.3, the squeegeeing property is evaluated as that the powder can be spread into a uniform powder layer in the lamination shaping. Furthermore, if the 50% particle size of a powder obtained by a laser diffraction method is 3 to 250 μm, the squeegeeing property is evaluated as that the powder can be spread into a uniform powder layer in the lamination shaping.
