Creating a low-cost, low-particulate emissions corn cob charcoal grinder for use in Peru
Indoor air pollution is a serious health risk in developing countries, and is the leading cause of death for children under five. By replacing traditional cooking fuels with charcoal, one can significantly reduce a user's exposure to the particulate matter responsible for the detrimental health …

Development of a Cost Oriented Grinding Strategy and Prediction of Post Grind Roughness using Improved Grinder Models
… Another drawback with SAM exists in the built-in grinder models that do not factor in the effect of speed and depth of cut on the grinding head. High speeds or deep cuts will result in the grinding head riding out the cut and likely worsening the roughness. A constrained grinding strategy …

Elements for the design of precision machine tools and their application to a prototype 450mm Si-wafer grinder
Next generation precision machines will require ever more rigid elements to achieve the required machining tolerances. The presented work focuses on the application of ultra stiff servo-controllable kinematic couplings and hydrostatic bearings to minimize the structural loop of multi-axis precision …

Genetic Analysis of Grinder Formation in Caenorhabditis Elegans: Regulation by RAB-6.2 and Its GTPase Activating Protein EAT-17
The C. elegans grinder is an intricately designed, macromolecular structure located in the terminal bulb of the pharynx. It acts as the teeth of C. elegans, crushing bacteria before they are passed to the intestine. The grinder is a specialized cuticular structure and is shed and rebuilt at each …

Effect of Poor Sanitation Procedures on Cross-Contamination of Animal Species in Ground Meat Products
… Pork (13.6 kg) was processed using a commercial grinder, then one of three sanitation treatments was completed (“no cleaning”, “partial cleaning”, or “complete cleaning”). Next, beef (13.6 kg) was ground using the same equipment. For “no cleaning,” beef was ground immediately after pork without …

A determination of the extent to which a predominant representational system can be identified through written and verbal communication and eye scanning patterns.
… as hypothesized by Richard Bandler and John Grinder, could be identified through written, verbal, and eye scanning patterns as the instruments of measurement. A second purpose was to determine if the results obtained through the three measures were consistent.

Experiments and modeling of size reduction of switchgrass in laboratory rotary knife mill
… was applied to switchgrass size reduction by a grinder. Two population balance parameters, grinding rate (s⁻¹) and breakage distribution function (dimensionless) were estimated using experimental grinding data. The time dependent balance equations were solved using the Euler technique. The …

The Relationships of Three Aspects of Eye Movements to Internal Sensory Modes During Three Response Situations
… represent information. In addition to examining Grinder and Bandler's claim that the direction of first eye movement is related to internal sensory mode (visual, auditory, or kinesthetic), dominant position (where the eyes stayed longest), and activity rate (distance moved divided by time) were …

Modeling the lubrication of the piston ring pack in internal combustion engines using the deterministic method
… plateau part of the liner finish using a random grinder. The model successfully captures the statistic topological features of the worn liner roughness. Combining the piston ring pack model and the liner finish wear model, one can potentially predict the long term ring pack friction loss. Finally …
