Expectations three categories

It is important to identify areas in accordance with the expected degree of fire hazard to facilitate an appropriate and economical selection of electric motors. These areas, according to lEC 60079-10, are classified into three categories as follows. 

As seen from Table III, two-thirds of the pesticides found In ground water from agricultural uses fall In one of the following three categories carbamates, trlazlnes, and low molecular weight halogenated hydrocarbons. It can be expected that another class which will be found In this evolving field Is... 

Table 4-7 shows observed deaths in the three categories compared with age-specific expected numbers based on mortality data on U.S. white males born in 1891. In general, the observed expected ratios are lower than 1, apparently because the preinduction medical examinations excluded men not in good health. Deaths did increase sharply in the mustard-gas roster for 1930-1939. 

Because so many factors determine the response obtained for a chemical substance in a sample, it is usually not possible to derive directly the concentration from the measured response. The relationship between signal, or response and concentration has to be determined experimentally, a step which is called calibration. The complexity of the calibration depends upon the type of expected problems. These are roughly divided into three categories interferences, matrix effects or interactions and a combination of both, a so-called interacting interference. 

There appears to be some preference for leaflet B, but we need a formal statistical test to see if the trend is significant. Our null hypothesis is that all leaflets are equally likely to be selected and so our expected outcome is that each leaflet will be selected by90/3 = 30 patients. We then calculate y2 in the usual way (Table 15.6). Notice that Yates correction has not been applied as there are more than two categories. According to Table 15.3 (three categories), y2 would need to achieve a value of at... 

It must be clear for the control authorities that Article 17 represents a challenge for the operators of the food contact materials and articles chain not only to align, harmonise and deepen their internal and inter-chain system of product tracing and recall, but also to control appropriately, identify and penalise illegal behaviour. As outlined in section 4.2.1, there are three types of food contact materials and articles for which traceability must be ensured (i) materials and articles already in contact with food, (ii) those manufactured for food use but not yet in contact with food at the retail stage, and (iii) those that can reasonably be expected to be brought into contact with food or to transfer their constituents to food under foreseeable conditions of use. The traceability for these three categories can be different, in particular in relation to the traceability of food set forth by Article 18 of 178/2002/EC. 

The whole issue of BSE or mad cow disease has had a profound effect on the global rendering industry. Eor example, the North American exports of tallow into the European Union dropped from about 350,000 tons per year to less than 70,000 tons prior to 2003 and were expected to be further reduced after the EU s Animal Byproducts Regulations (ABPR) were put into effect in late 2003. The EU has maintained that feed-borne food crises such as BSE all point to control deficiencies in the animal feed sector. The new regulation builds on previous EU measures that required the exclusion of dead animals, specified risk materials (SRMs), and other condemned materials from feed, and the pressure treatment of mammalian materials intended for use in feed. It also bans intraspecies feeding of farmed animals. It classifies animal byproducts into three categories based on their potential risk to animals, the public, or the environment, and sets out how each category must or may be disposed of. 

The processes that control the diagenesis and redistribution of metals in the ocean are classified into three categories in this chapter (see Fig. 12.18) (A) oxic diagenesis, which includes adsorption onto deep-sea clays and onto iron-rich particles from active hydrothermal areas, (B) sedimentary anaerobic processes that occur primarily in continental margin sediments where oxygen is replete in bottom waters but depleted in porewaters near the sediment-water interface, and (C) diagenesis in fully anoxic sediments in areas where the bottom waters are anoxic. Each of these categories refers to reactions that alter trace metal concentrations in marine sediments from those to be expected on particles that enter the ocean via rivers. Thus, the concentrations or metal A1 ratios in marine sediments are often... 

Question 1. Would you normally have requested this determination on this patient had to be answered on all the tests. In the second question the clinician was asked, if the result was abnormal (that is, outside the limits listed in Table 1), to place it in one of three categories (1) an expected abnormal result (2) an unexpected abnormal result leading to a new or additional diagnosis (3) an abnormal result, unexpected and unexplained at the time of completing the questionnaire. 

We are going to shortly summarize the results of all three categories. The reuse aspect of tool construction is summarized later in this section after we have discussed how modeling has influenced tool construction and how general/specific the investigated tools are. It should be remarked again that the tool construction activities are not finished, the ongoing transfer projects are expected to produce further results. 

Rather than allow the unknown to keep them totally unprepared, however, they answer these questions by formulating three categories of expectations to increase their sense of confidence with foresight and to reduce their fear from ignorance with information ... 

We expect from this over-all exercise that there will emerge a number of carefully tailored, sharply focused options which the President will direct to come into being. We foresee at this time that the Presidential actions can fall into three categories. Those which will require legislation in which it will be necessary to enlist the aid of the Congress. Those which will require Presidential directive in the form of executive orders and... 

After this we should consider whether there have been any compositional changes In the pectin. This Is best determined by using column techniques to fractionate the three categories of pectlc material, and also by further analysing the pectins. If any changes are taking place as a consequence of processing, we would expect to see them reflected In at least some of these results. 

Light-induced electron transfer from an indole to an alkyl, vinyl, or aryl halide would be expected to yield a radical anion which can ionize by loss of halide ion. This would give a radical that can attack an indole and so lead to products of substitution. Examples of this reaction for all three categories of halide have been observed. Photolysis of an aqueous methanol solution of indole with methyl chloroacetate gives a mixture of all the possible isomers of methyl indolylacetate in low yield. The 4-substituted isomer is formed in greatest amount (6.2%) and the yields of the six other isomers vary from 0.24 to 2.55% [62]. Photolysis... 

Polymer blends are expected to create many useful novel materials with specific properties that cannot be achieved by individual polymers in the future. And blending is an easy and inexpensive method of modifying various properties of polymer. A polymer blend or polymer mixture is a kind of material analogous to metal alloys, in which at least two polymers are blended together to create a new material with tailored physical properties, which can be broadly divided into three categories immiscible, compahble, and miscible polymer blends. The immiscible blends are made of two polymers, and two glass transition temperatures will be observed. Compatible polymer blends are immiscible polymer blends that exhibit macroscopically uniform physical properties. The macroscopically uniform properties are usually... 

Helical polymer stmctures can be classified into three categories. The first is a rigid helix having a stable existence at room temperature. In this case, one may expect to obtain an optically active polymer with an excess of a screw sense through the polymerization process using a chiral initiator or catalyst. This kind of polymerization has been called helix-sense-selective polymerization (lUPAG nomenclature asymmetric...
