Automated Grease Dispenser
… were tasked with replacing the current system of grease lubrication currently in use during forging at Arconic Engines in Verdi, Nevada. The senior project established a design for which the current method of swabbing grease onto the drive roll of the mill could be replaced with an automated …

Grease removal by a completely mixed activated sludge plant and methods for enhancing grease removal
Various concentrations of grease were fed to a completely mixed activated sludge laboratory plant and the effects of blending and the addition of a surfactant on removal efficiencies were determined. Blended and unblended raw sewage containing grease was studied to obtain a comparison between the …

Grease particle deposition measurements in a kitchen exhaust duct for the development of low cost grease sensors.
Grease deposition in kitchen exhaust ducts is an imminent fire hazard. There exists the need to quantize and measure the amount of grease deposition in a commercial kitchen exhaust duct in a cheap and efficient manner. Results from a real cooking emission study (ASHRAE 1375-RP) were used to model …

Kinetics of the electrocoagulation of oil and grease
<p>Research on the electrocoagulation (EC) of hexane extractable materials (HEM) has been conducted at the University of New Orleans using a proprietary bench-scale EC reactor. The original reactor configuration forced the fluid to follow a vertical upward-downward path. An alternate electrode …

Studies on the natural fluorescence of wool and wool grease
… intense at the roots. The fluorescence of wool grease consists of two components - 'grease' and chlorophyll. The 'grease' fluorescence reveals the presence of a number of chromophores/components. An attempt to isolate these was only partly successful. Chlorophyll could be detected in all the …

Warburg studies of the oxidative activities of activated sludge subjected to varied concentrations of grease
… of varied concentrations of a natural sewage grease on the oxidative activities of activated sludge were investigated in an effort to determine the feasibility of using activated sludge as a treatment method for wastes high in grease content. The method employed to measure the oxidative …

Trust in science is not the answer to conspiracies: It’s throwing water on a grease-fire
Conspiracy theories can be quite dangerous and have risen in prevalence. The rise of conspiracy theories has been met with an outcry to increase public trust in science. However, using trust in science to stop conspiracy theories may have unintended negative consequences. Trust in science entails …

Green Diesel Production Via Catalytic Hydrogenation/decarboxylation Of Triglycerides And Fatty Acids Of Vegetable Oil And Brown Grease
… diesel, vegetable oil/animal fat/waste oil and grease derived hydrocarbons in diesel boiling range, has become an attractive alternative to biodiesel— a mixture of fatty acid methyl esters, particularly due to its superior fuel properties that are similar to petroleum diesel. Hence, green diesel …

Development of a Novel Grease Resistant Functional Coatings for Paper-based Packaging and Assessment of Application by Flexographic Press
… materials and methods for imparting oil/grease resistance to paper and/or paperboard used in packaging. The performance of a novel grease resistant functional coating comprised of polyvinyl alcohol (PVA), sodium tetraborate pentahydrate (borate) and acetonedicarboxylic acid (ACDA) and the …

Enhanced degradation of fats, oils and greases in domestic wastewater sewer networks and grease interception systems using peat humic substances
… in enhancing the degradation of fats, oils and greases (FOG) was investigated under controlled laboratory conditions using bench scale well-mixed bioreactors. An experimental design was used to evaluate the effects of temperature and peat humic substance (PHS) concentration on FOG degradation in …

The measurement of the running torque of oil and grease lubricated instrument ball bearings under combined radial and axial loads
… By comparing lubricants, it was concluded that grease lubricated ball bearings demonstrate running torques approximately twice as great as bearings lubricated with a similar weight of oil.

Exogenous enzymes and irradiation of barley reduce the anti-nutritional activity of non-starch polysaccharides in broilers
… By adding either 10% soya oil or yellow grease (fat) as the lipid source, sub groups were created which differed in fatty acid profile. Lastly, these treatments were further subdivided by supplementing one of the two diets from each subgroup with a commercially available combination of …

Computational modelling of ice floe dynamics in the Antarctic marginal ice zone.
… considering separately ice floes and grease ice with their distinct properties. The material behaviour of ice floes is implemented using a Hookean-like flow rule, whereas grease ice is governed by a viscous-plastic material law. The small-scale model assumes that sea ice is isothermal, …

Investigating Tempo-Oxidized Cellulose Nanofiber Lubricating Greases Using Microscopy, Rheology, and Tribology
Lubricating grease plays a significant role limiting the negative effects of friction and wear present in moving components across a multitude of industries and applications. However, current materials commonly used to formulate greases often pose environmental risks during operation and disposal …

A study on wool characters
… influence clean yield were staple length and grease fleece weight. When staple length or grease fleece weight increased the clean yield also increased due to: (1) the material increase from the increased staple-length and the increased grease fleece weight; (2) the decrease of shrinkage …

Friction and Wear Performance of Lifeboat Launch Slipways
… such that it is usual to line the slipway with grease before every launch and recovery. This adds to the number of operations involved in a launch and has safety implications. The use of grease to line the slipway results in the grease being washed out to sea with effects on the surrounding …

PAH and PCB distribution in sediment fractions and sorptive phases
… Bioavailability of contaminants in oil and grease, soot and organic carbon, components of sediment total organic carbon (TOC), may be vastly different. Physical properties are also different and determine fate during treatment. This study focused on the relative distribution of PAHs and PCBs …
