Picking out

Front air bags are important invention, saving human lives. However, front air bags are not the ideal solution and need improvements or a replacement by a better solution. You have a rare opportunity to save human lives and to make a fortune if you find a better safety measure than an air bag. It should work in all kinds of collisions. [Pg.224]

Students reacted with real interest, showing even emotional involvement (many had had relatives or friends killed in car accidents) and had many questions. After that they were ready to move to the next step in the brainstorming process. [Pg.224]


Determination of purity. The ultraviolet and visible absorption is often a fairly intensive property thus e values of high intensity bands may be of the order of 10 -10 . In infrared spectra e values rarely exceed 10 . It is therefore often easy to pick out a characteristic band of a substance present in small concentration in admixture with other materials. Thus small amounts of aromatic compounds can be detected in hexane or in cyclohexane. [Pg.1149]

Pick out the longest continuous carbon chain and find the lUPAC name m Table 2 2 that corresponds to the unbranched alkane having that number of carbons This is the parent alkane from which the lUPAC name is to be derived... [Pg.72]

Its linear geometry makes it easy to pick out a triple bond in a molecular model... [Pg.364]

At first glance splitting may seem to complicate the interpretation of NMR spectra In fact It makes structure determination easier because it provides additional information It tells us how many protons are vicinal to a proton responsible for a particular signal With practice we learn to pick out characteristic patterns of peaks associating them with particular structural types One of the most common of these patterns is that of the ethyl group represented m the NMR spectrum of ethyl bromide m Figure 13 15... [Pg.538]

Mass Spectrometry Aside from a peak for the molecular ion which is normally easy to pick out aliphatic carboxylic acids undergo a variety of fragmentation processes The dominant fragmentation m aromatic acids corresponds to loss of OH then loss of CO... [Pg.821]

Once c is known, the monolayer point is picked out by use of the relation... [Pg.255]

The analysis was performed by SRXRF at the XRF beam-line of VEPP-3, Institute of Nuclear Physics, Novosibirsk, Russia. For the accuracy control the different types of the International Certified Reference Materials were used. There were obtained all metrological characteristics, namely precision, accuracy and lower limits of detections. This is the SRXRF method, that allow to analyze the sample mass of 0.5 mg directly without the destruction. The puncture from patient may be picked out more than once. [Pg.387]

Naively, one might assume that it should be possible to scan the sequence and pick out regions with about 20 consecutive hydrophobic amino acids. However, no such regions occur in the reaction center proteins. Just as in soluble proteins there are hydrophobic side chains at the... [Pg.244]

Staeking faults and sometimes proper polytypism are found in many inorganic compounds - to pick out just a few, zinc sulphide, zinc oxide, beryllium oxide. Interest in these faults arises from the present-day focus on electron theory of phase stability, and on eomputer simulation of lattice faults of all kinds investigators are attempting to relate staeking-fault concentration on various measurable character-isties of the compounds in question, such as ionicity , and thereby to cast light on the eleetronic strueture and phase stability of the two rival structures that give rise to the faults. [Pg.121]

Bastenie and Zylberszac, in a general article on the former subject, point out that colchicine (1) brings into mitosis all cells which are in karyo-kinetic inuninence but which normally would slowly and successively reach mitosis, and (2) stops them at this stage. This has made possible a technique which picks out cell multiplication and can be used for detecting many types of hormonal stimulation, e.g., the action of follicular hormone and other oestrogens. ... [Pg.657]

Self-contained versus companywide. Third, pick out those management systems that are self-contained within a given business unit or department, versus those that apply throughout the company. For example, does each facility have its own system for safety training, or do all operations follow a corporate system ... [Pg.66]

The standard orientation for the molecule, and specifically the coordinates of the atoms of interest. Sometimes, the atomic numbers alone are enough to identify the atoms you want, but for larger systems, the center numbeis will be needed to pick out specific atoms within the standard orientation. Their coordinates will enable you to characterize the expected components of the displacement for the motion under investigation. [Pg.80]

In the following sections, I have tried to pick out some of the more familiar techniques and concepts that will form recurring themes throughout the text. [Pg.4]

In order to resolve the mixture melting at 135°, it should be dissolved in cold acetic ether to saturation, and allowed to stand so that the solvent evaporates very slowly. Two distinctly different forms of crystals separate which can be picked out and recrystallised separately, when the two semi-carbazones are obtained in a state of purity. [Pg.186]

In order to construct an expression representing an arbitrary Boolean function J-, we must therefore j)erform two simple steps (1) construct expressions of the above form for each occurrence of a 1 in J- s truth table, and (2) join each such expression by the OR operator. Since each term is explicitly constructed so as to pick out a particular input configuration yielding the value 1 under J-, no more than one such term in the resulting OR expansion can yield the value 1 for a given input. All other configurations are identically zero. [Pg.312]

It would take us too far out of our way to explore the territory opened up by this way of looking at Polya s Theorem, but we can take a quick look at the view and pick out some of the salient features. The cycle index, in its new clothes, is expressible in terms of -functions conversely, an 5-function can be regarded as a sort of cycle index. The 5-function for a partition can be defined by... [Pg.122]

Extraction and purification (Shimomura et al., 1978). Dr. Yata Haneda and Dr. Shoji Inoue kindly provided us with specimens of O. gracilirostris, which had been picked out one by one from large commercial catches of Sergestes lucens netted in Suruga Bay, Japan. The material was air-dried or freeze-dried before shipment to the U.S. [Pg.82]

This is a questionnaire. On the questionnaire are groups of statements. Please read the entire group of statements in each category. Then pick out the one statement in that group that best describes the way you feel today, that is, right now Circle the number beside the statement you have chosen. If several statements in the group seem to apply equally well, circle each one. [Pg.288]

Chromatograms demonstrating the simultaneous use of all three detector functions are shown in figure 22. It is seen that the anthracene is clearly picked out from the mixture of aromatics by the fluorescence detector and the chloride ion, not shown at all by the UV adsorption or fluorescence detectors, clearly shown by the electrical conductivity detector. [Pg.190]

The compounds of Mg with Ca, Sr and Ba are also simply prepared mixtures of different proportions are heated to above the liquidus temperature and cooled for examination under inert conditions. Single crystals can be picked out from those alloys that contain a distinct compound phase as detected by x-rays. ... [Pg.404]

Notice that by the inclusion of Tg, the mean is much more strongly influenced than the median. The value of such comparisons lies in the automatic processing of large numbers of small data sets, in order to pick out the suspicious ones for manual inspection. (See also the next Section.)... [Pg.15]
