Organic grains may be contracted prior to planting. Contracts vary considerably, some make producers responsible for grain cleaning or shipping charges or both, while others do not make the producer responsible for either. 

Chlorine gas is produced by the electrolysis of brine (sodium chloride) in Castner-Kellner cells (first operated in 1886), the main purpose of which is the production of sodium hydroxide solution. Williams (1972, p98) reports that the extent to which the Castner-Kellner process was worked in Britain depended on the ability to dispose of the chlorine. In this light the production of chlorinated organic compounds can be seen as a response to the need to use chlorine. The argument that we need to produce chlorinated organic compounds to use up chlorine was indeed put to me by manufacturers of polyvinyl chloride (PVC) at a DETR-organized seminar on the lifecycle assessment of PVC in July 2001 PVC is the only product made in sufficient quantities to use up all the chlorine produced by other processes. This suggests that if a particular use of a chemical is stopped, because there is a better (less hazardous) way of achieving that purpose, it will have knock-on effects on the availability of chemicals that are co-produced... 

On the other hand, a variety of linkages has been detected in microbial galactomannans,l2,13-16,17 and, in addition, the sugar residues are frequently present in the furanoid form.12-14 These polysaccharides are produced by organisms responsible for a number of skin diseases, including, amongst others, the dermatophytes 17 the galac-... 

A recent survey in Scotland indicated that consumers appeared to delegate responsibility for ethical issues in meat production to the meat retailer or the government (Andersen et al., 2005). This was attributed to the fact that consumers did not seem to wish to be reminded about issues connected with the animal when choosing conventionally produced or organic meat (McEachern and Schroder, 2002). Moreover, organic meat was perceived as expensive, especially when consumers did not perceive a positive difference in quality. This resulted in some consumers being more interested in conventional meats with added-value features or from animals housed under improved welfare conditions rather than organic meat. 

OTA is an organic compound that does have IR absorbance however, it is present in concentrations (some p.g/L) that are too low to permit its direct determination. In this particular case it has been demonstrated that Aspergillus carbonarius, the organism responsible for the production of OTA, also produces other organic... 

Advances include radioprotective drugs applied during radiotherapy of neoplastic diseases. Effects similar to the enzyme superoxide dismutase have been found in copper complexes of Schiffs bases (derived from different amino acids and salicylaldehyde). Activity of complexes is dependent on their structures. The structural changes of their chelate rings are responsible for their effects on free radicals produced in organisms during radiation. Complexes have square pyramidal pentacoordination, which is similar to the coordination polyhedron in the active center of the Cu-dependent superoxide dismutase. The complexes used as radio-protective drugs play an important role in radiotherapy. They protect healthy tissues and cells from injurious radiation. ° ... 

In contrast a number of isolated organ preparations have been used as bioassay systems. Historically bioassay systems were developed when the nature of the chemicals themselves were often unknown and/or the sensitivity of chemical methods was insufficient to measure the extremely small concentrations of chemicals necessary to produce responses in bioassay systems. Thus, these systems could be used not only to measure the effect of the chemical on the system, but once the system was calibrated the concentration of a solution of the chemical could be determined based on the response it produced in the system. Furthermore, bioassay systems allowed for the demonstration of specific principles. For example, the desionstration by Loewi... 

Antibodies (ab) are high-molecular weight soluble proteins (immunoglobulins) produced by organisms in response to foreign substances (antigens, ag), with whom they form immunochemical complexes ... 

Due to the abundance and the nature of the primary compounds involved in these reactions, Cl chemistry has become a major area of research interest. CH4 (main component of natural gas) may be considered as a raw material for the next decades to produce various organic intermediates (chemicals, liquid fuels), as well as a principal source of energy. CO2 is the largest by-product emitted to the atmosphere and partially responsible for the green house effect. For this latter reason, its reutilisation is strongly desirable. CH3OH is a synthetic compound that allows numerous chemical transformations of great interest in the production of intermediates for the chemicals industry. Also CO (or CO + H2 mixture, usually called synthesis...
