How does it work

A basic assumption is that the organic grower will harvest at worst two-thirds of the yield obtained by the conventional grower. The economics of using chemical inputs depend on prices high enough to justify the use of those chemicals. Table 1.1, using 

At EU prices, the non-organic farmer is at a 40 per acre disadvantage. The organic price premium seeks to restore the balance, and if the organic farmer receives an extra 20 per tonne for his output then he is on a par with his conventional counterpart. If there were no price supports, both farmers would be worse off, but the organic farmer would be the better off of the two, and the consumer and the environment would benefit. 

The cost to society and the consumer of the European Union price subsidy is huge  

If farmers were paid to be custodians of the countryside, with a payment based on acreage 

The aesthetic and amenity value of the countryside would be enhanced.

Reik It is sort of the wrong way round. If stem cells proliferate and CLV3 is a short range factor, they move away from this signal and lose it. This should then activate WUS. If you say that this is some kind of feedback system to regulate the size of the stem cell pool, how does it work ...

The origin of the idea that a ribosome might be a ribozyme is derived from the experiment in which peptidyl transferase activity was observed even after digestion of protein components of the ribosome [15]. This was surprising because the most important biological function involved in the synthesis of proteins is catalyzed by RNA. Recently, a large ribosomal subunit from Haloarcula marismortui was determined at a resolution of 2.4 A [16, 155]. Importantly, because of the absence of proteins at the active site, it was concluded that the key peptidyl transferase reaction is accomplished by the ribosomal RNA (rRNA) itself, not by proteins. How does it work ... 

It is as if our consciousness were stabilized—in the domain of adaptive optimism—by a host of factors impinging on the brain-mind. These factors range all the way from raw energy (in the forms of photons and heat) up to the most abstract internal constructs about our self-worth and our place in our social world. This makes all kinds of sense. But how does it work What makes it fail And if it does fail, how can we establish a new equilibrium ... 

In the first case, a literature review provides a large set of available and applied techniques, both at the conceptual level (e.g., how does it work, what does it do, how is the technique founded in science, and how well is a technique validated ) and in the technical details. When no validated technique is available, general scientific knowledge, such as deriving a novel type of specific extrapolation model from specific data, can be developed.

As we have already mentioned, a monitor contains a CRT. But how does it work Basically, a device called an electron gun shoots electrons toward the back side of the monitor screen (see Figure 6.19). The back of the screen is coated with special chemicals (called phosphors) that glow when electrons strike them. This beam of electrons scans across the monitor from left to right and top to bottom to create the image. 

These examples demonstrate clearly that charge densities of uranyl-based sheets are in general smaller than charge densities of metal phosphate and vanadate units in lamellar compounds. However, the very existence of nanocomposite vanadates and metal phosphates means that the charge-density matching principle in these compounds is observed. Then how does it work for...

Alum has another Important use it helps purify water, making it clean and safe for you to drink. How does it work When we add alum to a tank of dirty water, it sticks to the dirt and mud. This helps form globs that sink to the bottom. Then the clean water flows off the top. 

How does it work from the mechanistic point of view Contrary to common trypsin substrates, the acyl residues of these enzyme-substrate mimetic arrangements bind to the S -subsite of trypsin (Fig. 12.5-18). For this reason, all binding sites beyond Si are only of minor importance for the substrate mimetics. Furthermore, the acyl residues of the substrate mimetics do not reflect the specificity of the S-...
