Direct Reduced Iron - Open Source Ecology

Often abbreviated as DRI. Direct-reduced iron is a metallic material formed by the reduction removal of oxygen of iron oxide iron ore at temperatures below the melting point of iron. DRI is produced by the use of a reducing gas mostly a mixture of hydrogen and carbon monoxide .

Direct reduced iron - Wikipedia

Direct reduced iron DRI , also called sponge iron, is produced from the direct reduction of iron ore in the form of lumps, pellets, or fines to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting ...

Ecology - an overview ScienceDirect Topics

P. McManus, in International Encyclopedia of Human Geography, 2009. Ecology is the study of living organisms and the relationships between organisms and their environment. Ecology is also used in a nonscientific sense to highlight the importance of connections, rather than surrounds. It may also be used to describe different political or philosophical movements concerned with the environment ...

Journal of Applied Ecology : Vol 57, No 10

Long‐term grazing intensifi ion degrades the population structure of grasses, particularly in high‐aridity sites, where the forage provision is substantially reduced . These results refute the hypothesis that plant traits of dominant species adapted to high aridity allow them to resist herbivory.

We experimentally simulated drought, which reduced water content in alfalfa plants. While water stress in alfalfa had no direct effect on spotted aphids, it lowered the population growth rate of pea aphids, another common alfalfa pest.

Recruitment biology - Wikipedia

In behavioral ecology and studies of animal communi ion, recruitment is the process by which individuals in a social group direct other individuals to do certain tasks. This is often achieved through the use of recruitment pheromones that direct anywhere from one to several hundred individuals to important resources, like food or nesting sites. 2

Direct Reduced Iron and its Production Processes – …

Direct reduction can be defined as reduction in the solid state at O2 potentials which allow reduction of iron oxides, but not of other oxides MnO, and SiO2 etc. , to the corresponding elements. Since reduction is in the solid state, there is very little chance of these elements dissolving at low thermodynamic activity in the reduced iron, so the oxides which are more stable than iron ...

Intraspecific competition - Wikipedia

Intraspecific competition is an interaction in population ecology , whereby members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals, but the more fit individual survives and is able to reproduce. By contrast, interspecific competition occurs when members of different species compete for a shared resource.

Environmental impact of irrigation - Wikipedia

Direct effects. An irrigation scheme draws water from groundwater, rivers, lakes or overland flow, and distributes it over an area. Hydrological, or direct , effects of doing this include reduction in downstream river flow, increased evaporation in the irrigated area, increased level in the water table as groundwater recharge in the area is increased and flow increased in the irrigated area.

Recruitment biology - Wikipedia

When discussing population dynamics, behavioral ecology , and cell biology, recruitment can refer to several different biological processes. In population dynamics, recruitment is the process by which new individuals are added to a population, whether by birth and maturation or by immigration. When discussing behavioral ecology and animal communi ion, recruitment refers to communi ion that ...
