The carbon cycle explains how carbon is made available to life forms. The main processes of the carbon cycle are photosynthesis, respiration, decomposition, natural weathering of rocks and burning fossil fuels. Plants absorb it from the atmosphere in the form of carbon dioxide.
This idea can be very useful when working with big numbers, such as in cryptography. Prime factorization is very important to people who try to make (or break) secret codes based on numbers.
The primary byproducts of aerobic decomposition — the “waste products” of the process — are carbon dioxide and water. In healthy soils or aerobically decomposed animal waste, there exists an entire food chain of bacteria feeding on other bacteria, and larger organisms feeding on the smaller.

The decomposition of an ideal into primary ideals is a traditional pillar of ideal theory. It provides the algebraic foundation for decomposing an algebraic.
Hence, decomposition is a metabolic process, taking up raw materials in the form of complex compounds, processing it and then converting it into simpler compounds. Bacteria, fungi and a few other microorganisms initiate the process of decomposition and are known as decomposers.

Decomposition is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere.
A new algorithm is presented for computing primary decomposition of zero- dimensional ideals over finite fields.
The primary decomposition is a result of a heat flux at the propellant surface which is sufficiently high so that only a very thin layer of propellant is affected before ig- niticn occurs. In this case heat generation by solid phase reaction need not be consiaerea.
One important result of this generalization that we will see is that in a special class of rings called noetherian rings, every ideal has a primary decomposition.
Abstract:the numerical simulation of biomass combustion requires a model that must contain, on one hand, sub-models for biomass conversion to primary products, which involves calculations for heat transfer, biomass decomposition rate, product fractions, chemical composition, and material properties, and on the other hand, sub-models for volatile products transport inside and outside of the biomass particle, their combustion, and the char reduction/oxidation.

One way to approach this is to start with primary decomposition. Properties (i) and (iii) are enough to show that every proper ideal is uniquely a product of primary ideals with distinct radicals. Then condition (ii) is brought in to show that the only primary ideals are powers of primes.
Decomposition in plants the primary decomposers of most dead plant material are fungi. Dead leaves fall from trees and herbaceous plants collapse to the ground after they have produced seeds.
Decomposition of organic material in the compost pile depends on maintaining microbial activity. Any factor which slows or halts microbial growth also impedes the composting process. Efficient decomposition occurs if aeration, moisture, particle size, and a sufficient source of carbon and nitrogen are in evidence.
During pyrolysis the primary decomposition products may participate in further chemical reactions, depending on their residence time within the high temperature zone. The hot charcoal is said to catalyze secondary pyrolysis reactions which are very exothermio.
Primary decomposition products are mg(g) and o(g), with only a very small amount of mgo(g). 17 we were unable to find data on how activity of mgo changes in solution. In order to estimate an upper limit, we shall use the value of a(mgo) along the mgo-rich cubic phase boundary. Since this is in equilibrium with essentially pure mgo, the activity.
One major application of decomposition reactions is in the extraction of metals from their ores. For example, zinc can be obtained from calamine by subjecting it to a decomposition reaction. In a similar manner, sodium can be obtained from sodium chloride (nacl).
