EJ201 and EJ202 Subaru Engines

The EJ201 and EJ202 engines had an aluminium alloy cylinder head with cross-flow cooling. Unlike the EJ20 engine, the intake ports for the EJ201 and EJ202 engines created a 'tumble swirl' motion for air as it entered the cylinder for better mixing of the air and fuel for more uniform flame travel and faster combustion.

Determination of minimum inhibitory concentrations

Minimum inhibitory concentrations (MICs) are defined as the lowest concentration of an antimicrobial that will inhibit the visible growth of a microorganism after overnight incubation, and minimum bactericidal concentrations (MBCs) as the lowest concentration of antimicrobial that will prevent the growth of an organism after subculture on to antibiotic-free media.

Chemistry of Iron in Natural Water

The ferrous oxidation state, less strong in its complexing properties than the ferric, forms few inorganic complexes. Ferrous hydroxide, Fe(OH)2, is a stronger base than ferric hydroxide. The ionization products include FeOH+ and Fe++. Ferrous anions such as hypofer- rite, FeO2, form in strongly alkaline solutions.

Iron (Fe) and water

Green plants apply iron for energy transformation processes. Plants that are applied as animal feed may contain up to 1000 ppm of iron, but this amount is much lower in plants applied for human consumption. Generally plants contain between 20 and 300 ppm iron (dry mass), but lichens may consist up to 5.5% of iron.

Ecological Soil Screening Level for Iron

The divalent state (or ferrous state) can be oxidized to the trivalent state (or ferric state), where it may form oxide or hydroxide precipitates, and become unavailable to plants as a micronutrient (Thompson and Troeh, 1973). Roots of some plants are able to reduce iron from the ferric to the ferrous state, and allow iron uptake into the

SL353/SS555: Iron (Fe) Nutrition of Plants

In aerobic soils, the oxide, hydroxide, and phosphate forms control the concentration of Fe in solution and its availability to plants. In typical aerated plant production systems of acceptable reaction (pH) of +/- 6.0, the concentrations of ferric (Fe +++ ) and ferrous Fe ++ iron are on the order of 10 -15 molar (very low concentration).

Iron Nutrition Management in Plants - Smart Fertilizer

Plants uptake iron in its oxidized forms, Fe 2 + (ferrous form) or Fe 3+ (ferric form). Plants use various iron uptake mechanisms. One of these is the chelation mechanism – the plant releases compounds called siderophores which bind iron and enhance its solubility. This mechanism also involves bacteria.
