A thrombelastography device, a heating apparatus, a blood coagulation analysis system, and a rotational angle measurement method are disclosed. The thrombelastography device consists of a plurality of thrombelastography device splits (2) that are horizontally arranged in parallel. The thrombelastography device split (2) comprises a worktable (4), a rack (5), a test bar (6), a tester (8), and a processor (9). The thrombelastography device overcomes the defect in the prior art that the measurement result of a thrombelastography device is inaccurate. The amount of reflected light is used as a reference for thrombelastographic evaluation, and thus the result is more accurate.

The present disclosure relates to the determination of the rheological behavior of a fluid.

A centrifugation approach used to accelerate current empirical methods used to investigate silicone drainage in syringes is disclosed. A siliconized syringe is placed into a holder of a centrifuge in a predefined orientation. Centrifugation of the syringe is activated at a predetermined G rate and for a period of intended simulation time and is ended as that time elapses. The time can be a function of intended simulation time, acceleration due to gravity, square of centrifuge revolution rate, and distance from center of rotor hub to matching point on the syringe barrel. One or more injection functionality parameters of the syringe is assessed after the elapsed period of time. A bucket fixture for retaining one or more syringes in the predefined orientation is also disclosed.

A computer-readable storage medium storing a multilayer fluid analysis program is provided for analyzing a multilayer fluid on a feed block type T-die as 2.5 dimensions in which each layer is divided into elements. The program causing a computer to execute: a layer thickness calculation process for calculating the layer thickness under a condition that stresses in a normal direction and a tangential direction equilibrate on an interface of each layer and a flow velocity on the interface is continuous, without considering a fluid flow in a thickness direction, considering a viscoelastic effect of a fluid to analyze an encapsulation phenomenon, and based on a shape of the feed block and a second normal stress difference of resin assuming that a layer thickness in a transverse direction fluctuates in a developmental state; and a display process of displaying a calculation result of the layer thickness calculation process.

A method for checking an oil as a lubricant for an internal combustion engine includes: performing a laboratory test in which, independently of the internal combustion engine, a three-dimensional temperature-viscosity-shear rate characteristic field which characterizes the oil is determined, which includes a plurality of viscosities, shear rates and temperatures of the oil determined experimentally by the laboratory test and in each case associates shear rates and viscosities with the temperatures; checking whether the temperature-viscosity-shear rate characteristic field meets at least one predeterminable first criterion; and if the temperature-viscosity-shear rate characteristic field meets the first criterion: performing at least one test bench trial in which, via the internal combustion engine, it is checked whether the oil meets at least one predeterminable second criterion.

Systems and methods are disclosed for providing virtual assays of an oil sample such as crude oil based on near infrared (NIR) spectroscopy carried out on the oil sample, and the density of the oil sample. The virtual assay provides a full range of information about fractions of the oil sample including naphtha, gas oil, vacuum gas oil, vacuum residue, and other information about the properties of the oil sample. Using the system and method herein, the virtual assay data pertaining to these several fractions of the oil sample and the oil sample itself are obtained without the need to fractionate the oil sample into the several components.
