We value process in writing instruction. How, then, can we communicate an appreciation for process as much as results to our colleagues To administrators How can process be as visible as bar graphs and pie charts Context-sensitive assessment highlights process as a generative, productive stage. 

The user-interface for the operators was based on the formalized ontology for the production process, as developed so far. The various tasks, interventions, error categories and error details and the available counter measures were all retrieved from this ontology. This allowed to record the user activities during production, and to store this data with its appropriate context to enable context-sensitive data-mining across all available data sources. To-... 

Note that all context sensitive productions are of type 0, all context free productions are context sensitive, and all regular productions are context free. 

Once the production resources have been selected, it is necessary to select the appropriate values for controllable parameters in manufacturing operations, hi product manufacturing scenarios, parameters such as cutting speed, feed, and depth of cut or width of cut need to be selected for each feature. In provision of services, parameters are more context sensitive. For example, in providing a helpdesk to technically support a software system, the number of persormel is a parameter that needs to be chosen. Various models are used for selection of operational parameters including the minimum cost models that seek to minimize the overall resource cost of the operation, maximum production rate models that aim to realize the highest possible throughput and lead time- oriented models that strive to lower the production s time to market. 

Detection by LDMS and structural elucidation of other secondary metabolite products, generated in the host during the onset of the parasite disease, is discussed. These molecules may serve as additional biomarkers for rapid malaria diagnosis by LDMS. For instance, choline phosphate (CP) is identified as the source of several low-mass ions observed in parasite-infected blood samples in addition to heme biomarker ions. The CP levels track the sample parasitemia levels. This biomarker can provide additional specificity and sensitivity when compared to malaria detection based on heme ion signals alone. Furthermore the observed elevated CP levels are discussed in the context of Plasmodium metabolism during its intra-erythrocytic life cycle. These data can... 

Though the triplet sensitized photolysis of isoprene (159) does, as noted above, produce a complex mixture of products, one of these adducts has been used in the context of complex molecule synthesis (equation 5)71. Cyclobutane 160, which was formed in ca 20% yield by the benzophenone sensitized photolysis of 159, could be easily transformed into fragrantolol, 161, an isomer of grandisol isolated from the roots of the Artemisia fragrans, by simple hydroboration/oxidation of the less hindered double bond. 

The most problematic obstacles in this context are the limited in vivo production activities of the conventional algal cultures and the 02 sensitivity of the known chlorophycean [Fe]-hydrogenases. Therefore it is important to find or develop alternative strains, with a higher physiological productivity and a reduced oxygen sensitivity. In this article we presented two different strategies which in combination could sooner or later lead us to this aim. 

The hydrogen production mix is very sensitive to the country-specific context and strongly influenced by the assumed feedstock prices resource availability and policy support also play a role, in particular for hydrogen from renewable and nuclear energy. 

Reaction-based indicators which are catalytically transformed by the analyte of interest are an attractive alternative due to the simple reason mentioned in the context of enzymes at the beginning of Sect. 4 one analyte molecule is qualified to produce a lot of fluorophores, increasing sensitivity dramatically. For an actual quantitative determination, however, the same conditional constraints are relevant like in enzyme-based methods, i.e., reproducible and defined incubation times, temperature, pH, etc. Up to now, transition metal cations have been mostly shown to be detectable by catalytic fluorophore production. 

As the enzyme itself is usually the focus of interest, information on the behavior of that enzyme can be obtained by incubating the enzyme with a suitable substrate under appropriate conditions. A suitable substrate in this context is one which can be quantified by an available detection system (often absorbance or fluorescence spectroscopy, radiometry or electrochemistry), or one which yields a product that is similarly detectable. In addition, if separation of substrate from product is necessary before quantification (for example, in radioisotopic assays), this should be readily achievable. It is preferable, although not always possible, to measure the appearance of product, rather than the disappearance of substrate, because a zero baseline is theoretically possible in the former case, improving sensitivity and resolution. Even if a product (or substrate) is not directly amenable to an available detection method, it maybe possible to derivatize the product with a chemical species to form a detectable adduct, or to subject a product to a second enzymatic step (known as a coupled assay, discussed further later) to yield a detectable product. But, regardless of whether substrate, product, or an adduct of either is measured, the parameter we are interested in determining is the initial rate of change of concentration, which is determined from the initial slope of a concentration versus time plot.
