An active/resilient grinding media inside a tube containing a sample is oscillated rapidly by a homogenizer so that the active media is driven in a first direction until it impacts a first end of the tube, which causes it to deform and store an energy charge as it decelerates and stops, and it then accelerates rapidly in the second opposite direction under the discharging force of the stored energy toward the opposite second end of the tube. This cycle of the active media decelerating/charging and then discharging/accelerating is repeated throughout the entire oscillatory processing of the sample. The result is much higher velocities of the active media and therefore much greater impact forces when the sample and active media collide, producing increased efficiency in disruption and size-reduction of the sample particles.

Systems, apparatuses, and methods enable rapid, repeatable, and accurate dissection of arthropods. Arthropod dissection apparatuses includes a shear dissection mechanism having a primary shear body and a secondary shear body. The primary shear body includes at least an inlet channel, a first outlet channel, and a second outlet channel formed therein. The secondary shear body is disposed in an aperture of the primary shear body and has a dissection chamber formed therein. The secondary shear body is movable between a first position and a second position relative to the primary shear body, which causes a shearing action at a shearing interface between the secondary shear body and the primary shear body.

An intelligent lithology identification system and method based on images and spectrum technology. The intelligent lithology identification system includes a rock shape analysis system, an image identification system, a sample processing system, a spectrum analysis system, and a central analysis and control system; wherein the central analysis and control system determines the final lithology of a sample according to the rock identification results from the image identification system and the analysis results from the spectrum analysis system. The technical solution further identifies the content and type of minerals by using spectrum technology, integrates and analyzes the results of spectrum analysis and image identification, and finally gives the lithology of the rock, which greatly improves the accuracy of lithology identification.

An open system pyrolysis of a first hydrocarbon source rock sample obtained from a natural system is performed within a pyrolysis chamber by maintaining the pyrolysis chamber at a substantially constant temperature. Hydrocarbons are recovered from the pyrolysis chamber released by the first hydrocarbon source rock sample. A thermo-vaporization is performed within the pyrolysis chamber on the pyrolyzed sample at a substantially constant temperature. A first hydrocarbon expulsion efficiency of hydrocarbon source rock is determined. A second hydrocarbon rock sample is ground to a grain size less than or equal to or less than 250 micrometers. A second pyrolysis is performed on the ground hydrocarbon source rock sample by maintaining the chamber at a substantially constant temperature. A second hydrocarbon expulsion efficiency of the hydrocarbon source rock in the natural system is determined. The first hydrocarbon expulsion efficiency is verified using the second hydrocarbon expulsion efficiency.

A method of analysing granular material in a slurry, the method comprising: compacting the granular material in the slurry to form one or more pucks; irradiating said pucks with X-Ray radiation and detecting X-ray energy transmitted through said one or more irradiated pucks; irradiating a reference material with X-Ray radiation, said reference material having known material characteristics and detecting X-ray energy transmitted through said reference material; comparing X-ray energy transmission through said one or more pucks with the reference material to compute, using a processing unit, one or more particle characteristics of the granular material in the one or more pucks.

A system for treating cancer and evaluating chemo-preventive potential of PHC and its prepared chitosan nanoparticles is described. The rats are divided into eight groups, from which group 1 is served as normal control, and group 2-8 are given single dose of DEN and repeated dose of CCl.sub.4, wherein freshly prepared solution of DEN in normal saline is used for the induction of HCC in rats by administering 200 mg/kg, i.p., PHC (2:1:1) in normal saline suspension to administer at doses of 900 mg/kg, wherein serum and tissue samples are collected after anesthetizing overnight fasted rats using intraperitoneal administration of thiopentone sodium at a dose of 40 mg/kg, wherein the collected serum and tissue samples is treated and thereby the chemo-preventive potential of PHC (2:1:1) and its prepared chitosan nanoparticles is evaluated upon determining liver markers, antioxidant parameters, total bilirubin, protein, lipid peroxidation, and liver cancer biomarkers.

The apparatus for measuring performance of a suspension for cooling a computer processing unit is a measurement and testing tool allowing for the fabrication of new suspensions, and measuring and testing their short-term and long-term thermal performance in real time on any liquid-cooled computer processing unit. The suspension is prepared in a sample receiving reservoir and pumped across the unit, and then input to an air-cooled heat exchanger for recirculation back to the sample receiving reservoir. Temperatures of the working fluid are measured between the sample receiving reservoir and the computer processing unit, between the unit and the heat exchanger, and after output from the heat exchanger. Pressure differentials of the working fluid is measured across the computer processing unit and across the heat exchanger.
