Blind spots

Muns ENDOR mvolves observation of the stimulated echo intensity as a fimction of the frequency of an RE Ti-pulse applied between tlie second and third MW pulse. In contrast to the Davies ENDOR experiment, the Mims-ENDOR sequence does not require selective MW pulses. For a detailed description of the polarization transfer in a Mims-type experiment the reader is referred to the literature [43]. Just as with three-pulse ESEEM, blind spots can occur in ENDOR spectra measured using Muns method. To avoid the possibility of missing lines it is therefore essential to repeat the experiment with different values of the pulse spacing Detection of the echo intensity as a fimction of the RE frequency and x yields a real two-dimensional experiment. An FT of the x-domain will yield cross-peaks in the 2D-FT-ENDOR spectrum which correlate different ENDOR transitions belonging to the same nucleus. One advantage of Mims ENDOR over Davies ENDOR is its larger echo intensity because more spins due to the nonselective excitation are involved in the fomiation of the echo. [Pg.1581]

Here we set out the arguments for, and provide examples of, simulations that complement rather than replace managerial judgment, making best use of whatever factual information is available to help managers make the necessary choices between possible futures. Such simulations are most needed in support of decisions where even experienced research leaders have blind spots in their judgment. [Pg.260]

Patients with severe disease progression may report loss of peripheral vision and may describe the presence of scotomata (blind spots) in their field of vision. [Pg.913]

While there is always this possibility of a blind spot, for discrete variables the one-at-a-time procedure is still frequently used. For continuous variables other procedures, which follow, should be used. [Pg.395]

The solution to access the invisible areas is readily copied from texture analysis tilt the sample by y and receive 1 data point on the meridian that corresponds to S3 = (2/A) sin y/. The result of the mapping is shown in Fig. 2.7. Thus by recording a series of images taken at different tilt angles of the fiber the blind area can be covered to a sufficient extent. Finally, the remnant blind spots may be covered by means of... [Pg.46]

The applicability of the ESE envelope modulation technique has been extended by two recent publications115,1161. Merks and de Beer1151 introduced a two-dimensional Fourier transform technique which is able to circumvent blind spots in the one-dimensional Fourier transformed display of ESE envelope modulation spectra, whereas van Ormondt and Nederveen1161 could enhance the resolution of ESE spectroscopy by applying the maximum entropy method for the spectral analysis of the time domain data. [Pg.47]

In general, charge cocomplexants exhibit dramatically different retention characteristics than the product of interest and will not reassociate spontaneously after a sample has been injected. The blind spot in this generalization is the potential for postelution reformation of complexes between the product and buffer components, chiefly phosphates and citrates with strongly alkaline proteins. If you are going to use such buffers, at least run a parallel control experiment with a monovalent buffer. [Pg.70]

To help with the constant monitoring, workers placed a video camera high in the opposite comer of the room, providing visual coverage of blind-spots. In addition, a hinged panel below the mirror became a small desk, ideal for administering paper and pencil tests or passing food and fluids to the volunteers. [Pg.71]

Other reported effects of exposure to carbon disulfide are ocular changes (blind spot enlargement, contraction of peripheral field, corneal anesthesia, diminished pupillary reflexes, nystagmus, and microscopic... [Pg.121]

Polymer science is underdeveloped in terms of descriptions of the structure and properties of stiff-chain polymers. The conducting polymers fall mostly within this blind spot. They also present a number of novel possibilities such as the conversion from a flexible-chain precursor to a rigid-chain polymer, and the conversion between doped and undoped states in the soluble polythiophenes. Likewise, solid-state physics has yet really to tackle the transport of electrons in, and between, disordered, twisted chains. For each of the disciplines involved, the explosion of interest in conducting polymers has brouht a host of new question and new ideas. The process is far from over. [Pg.90]

The information gathered by the receptors leaves the eye through the optic nerve. The optic nerve is formed by all the axons of retinal ganglion cells. Since these axons must leave the eye at some point, this causes a blind spot. There are no receptors at this blind spot. Even though a small area near the center of the image does not contain any sensors, we do not consciously perceive this lack of information. The human brain fills in the missing information. [Pg.16]

Periodic third-party reviews are an invaluable tool for identifying blind spots within an organization. Do not hesitate to augment the company s internal audit efforts with outside experts who are familiar with similar company operations. [Pg.638]

Advances in fabrication technology have made possible the production of very precisely aligned and spaced hollow fibers. Flow across such fiber arrays can thus be regulated to minimize boundary layer effects or blind spots very high mass transfer efficiencies have been achieved in this manner. [Pg.404]

A more serious flaw occurs because the neural wiring must poke directly through the wall of the retina to carry the nerve impulses produced by photoreceptor cells to the brain. The result is a blind spot in the retina—a region where thousands of impulse-carrying cells have pushed the sensory cells aside. [Pg.222]

A designer would have made the vertebrate eye without a blind spot. [Pg.224]

The electroplating of reflective surfaces for exterior mirrors is an important and growing application. Moulding is to a high standard of precision and the electroplated surface creates a mirror with excellent reflection. It will resist impact much better than glass so a longer life in service can be expected— hence, such mirrors are fitted extensively on commercial vehicles, buses, and lorries. ABS is moulded and electroplated also into small mirrors that can be fixed by adhesive on vehicle wing mirrors to cover blind spots . [Pg.185]

Industry uses benchmarking for everything costs, supply chain, all those kinds of things. Maybe that is where people need to go in hiring to benchmark departments in terms of what is or is not a good environment and to look for the blind spots. We heard from folks who have a proactive department they have a critical mass of women, yet it is still perceived to be a hostile environment. Where are the blind spots Benchmarking should be able to help. [Pg.102]

Steam baths are an inexpensive and useful way for heating mixtures up to 100 Celsius. Steam baths can also be used to heat mixtures from 50 to 90 Celsius. Steam baths are very easy to use and operate, and they heat mixtures without blind spots. Blind spots occur... [Pg.11]

As a result of equation (9), the Mims ENDOR signal is minimal ( blind ) at t = (n/Aiso), n = 0 (which is experimentally meaningless), 1,2,..., and is maximum at T = [(In -F l)/2Aiso]. Mims ENDOR spectra of a broad H pattern can clearly show the oscUlating blind spot pattern... [Pg.6547]
