High-pressure injection gun (Grease-gun) injuries mainly occur with industrial labourers. Injuries associated with high pressure grease guns are very rare and frequently involve the hand and chest. The non-dominant hand is generally injured since the grease gun is usually held in the dominant hand. Even if high-pressure injection injury causes only a small lesion in the skin, it is still charac...

Bimbo – Ricolino candy manufacturing plant in Mexico City was discharging wastewater with high amount of fats oil and grease and dissolved sugars. Local regulatory agency requested that suspended solids, oil and grease and dissolved BOD be almost completely removed prior to discharge to municipal plant. The available real estate in Mexico City was very limited. A multistep treatment system was ...

Bearing fatigue life is calculated using a so called basic rating equation L10=CPp where the operating load translated into an equivalent P and divided by bearing capacity. This makes it possible to test capacity C under arbitrary therefore on almost any rig. For grease such concept does not exist. Grease specified number of hours running standardized rigs conditions. A similar as for introduce...

Abstract Lubricating greases are widely used in e.g. open gear drives and gearboxes with difficult sealing conditions. The efficiency heat balance of grease-lubricated depend strongly on the lubrication mechanisms channeling circulating, for which grease flow is causal. computational fluid dynamics opens up possibility to visualize understand more detail. In this study, a single-stage gearbox l...

An experiment was conducted to determine the effect of supplementing diets fed to growing pigs with fat sources differing in their composition of fatty acids on the apparent total tract digestibility (ATTD) of minerals. A diet based on corn, potato protein isolate, and 7% sucrose was formulated. Five additional diets that were similar to the previous diet with the exception that sucrose was rep...

Grease to grease - this is how one might begin to describe the tendency of hydrophobic stretches in protein amino acid sequences to form transmembrane domains. While this simple rule contains a lot of truth, the mechanisms of membrane protein folding, the insertion of hydrophobic protein domains into the lipid bilayer, and the apparent existence of highly polar residues in some proteins in the ...

Wastewater treatment for removal of organic matter, inorganic matter and heavy metals is becoming increasingly important area of research. The disposal of wastewater to sea and other reservoirs can cause serious environmental problems. Wastewater from petroleum and refineries contains organic matter in various forms. Biodegradable and nonbiodegradable pollutants call for different biological an...
