An accurate description of visual symptoms is the key to diagnosis. Patients with static or progressive deficits can be examined while symptoms are present. It is helpful to instruct patients that if they have more episodes in the future they should cover each eye in turn during the episodes and pay careful attention to how this affects their symptoms.

In commencing the paper which I am about to read I would like, first of all, to make a few remarks as to what has been done towards solving the difficult, yet extremely fascinating problem of aerial flight.In recent years much has been attempted, but, when all is weighed in the balance, I venture to think that comparatively nothing of any value has yet been accomplished, and the successful flying machine has yet to come. A debt of gratitude is due to M. Santos Dumont. M. Lebaudy, and other pioneers, for breaking down, as they have, prejudice against the subject; but, after all, do his or their machines embody any new principle ? Only by careful attention to certain mechanical details and a combination of mechanism already in existence have they accomplished what they have.It is unnecessary for me to go into details of the defects of navigable air-ships. Most students of aeronautics are, I think, agreed that the flying machine of the future will be one which is heavier than the atmosphere and presents the least surface of resistance when travelling horizontally.

Conventional Expression

In Ancient Greek, an impolite order can be uttered by means of a negative interrogative in the future tense (οὐκ ἐρεῖς; ‘Won’t you talk?’). The aim of this paper is to understand to what extent this type of utterance is impolite, and to explain how such a conventional and indirect order can frequently take on an impolite meaning. For this purpose, data are taken from classical drama (Aristophanes’ and Euripides’ plays). Drawing on criteria put forward by recent work on impoliteness, this study provides an accurate description of uses in discourse, in order to establish that this conventional order is never used with a polite intention, but regularly as an impolite order. Impoliteness can be explained by the locutionary form which gives an orientation to the interpretation of the utterance: an indirect and conventional expression cannot be polite if the locutionary meaning is opposed to it.

In this paper, were using moving averages to pave the Neutrosophic time series. similar to use moving averages to pave the classical time series. the difference, here were dealing with inaccurate data and values of the time series.in the Neutrosophic time series, each unit of time(t) corresponds to a range of values instead of a single value. Finally, we find that the Neutrosophic time series provide an accurate description of the behavior of the series better than in the classic. Therefore, can predict the future of the series as accurately as possible.

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).

Second-epoch photographs have now been obtained for nearly 850 of the 1246 fields of the proper motion program with centers at declination -20° and northwards. For the sky at 0° and northward only 130 fields remain to be taken in the next year or two. The 270 southern fields with centers at -5° to -20° remain for the future.

Human And Mouse

Metaphase chromosomes from human and mouse cells in vitro are isolated by micrurgy, fixed, and placed on grids for electron microscopy. Interpretations of electron micrographs by current methods indicate the following structural features.Chromosomal spindle fibrils about 200Å thick form fascicles about 600Å thick, wrapped by dense spiraling fibrils (DSF) less than 100Å thick as they near the kinomere. Such a fascicle joins the future daughter kinomere of each metaphase chromatid with those of adjacent non-homologous chromatids to either side. Thus, four fascicles (SF, 1-4) attach to each metaphase kinomere (K). It is thought that fascicles extend from the kinomere poleward, fray out to let chromosomal fibrils act as traction fibrils against polar fibrils, then regroup to join the adjacent kinomere.

Detailed Nature

Ever since Habraken and Economopoulos first employed the term granular bainite to classify certain unconventional transformation products in continuously cooled steels, the term has been widely accepted and used, despite the lack of a clear consensus as to the detailed nature of the transformation products which constitute granular bainite. This paper presents the preliminary results of a TEM investigation of an 0.04 wt% C, copper-containing steel (designated HSLA-100). It is suggested that the term granular ferrite rather than granular bainite is a more accurate description of this multiphase reaction product.Figure 1 is a light micrograph of a sample which had been air-cooled from 900°C to room temperature. The microstructure is typical of that which has been termed granular bainite in the past and appears to consist of equiaxed ferritic grains together with other minor transformation products. In order to examine these structures in more detail, both continuously cooled and isothermally transformed and quenched materials have been examined with TEM. Granular bainite has been found in virtually all samples.

It is possible to exceed the guaranteed resolution on most electron microscopes by careful attention to microscope parameters essential for high resolution work. While our experience is related to a Philips EM-200, we hope that some of these comments will apply to all electron microscopes.The first considerations are vibration and magnetic fields. These are usually measured at the pre-installation survey and must be within specifications. It has been our experience, however, that these factors can be greatly influenced by the new facilities and therefore must be rechecked after the installation is completed. The relationship between the resolving power of an EM-200 and the maximum tolerable low frequency interference fields in milli-Oerstedt is 10 Å - 1.9, 8 Å - 1.4, 6 Å - 0.8.

Freeze Etching

In his pioneering demonstration of the potential of freeze-etching in biological systems, Russell Steere assessed the future promise and limitations of the technique with remarkable foresight. Item 2 in his list of inherent difficulties as they then stood stated “The chemical nature of the objects seen in the replica cannot be determined”. This defined a major goal for practitioners of freeze-fracture which, for more than a decade, seemed unattainable. It was not until the introduction of the label-fracture-etch technique in the early 1970s that the mould was broken, and not until the following decade that the full scope of modern freeze-fracture cytochemistry took shape. The culmination of these developments in the 1990s now equips the researcher with a set of effective techniques for routine application in cell and membrane biology.Freeze-fracture cytochemical techniques are all designed to provide information on the chemical nature of structural components revealed by freeze-fracture, but differ in how this is achieved, in precisely what type of information is obtained, and in which types of specimen can be studied.
