The first telegraph had been in operation only a short time when a code was made available to the users of the new instrument. From that time to the present, codes for use in electrical communications have appeared in ever-increasing number. Two principal objects have been sought and achieved by their use: secrecy and economy. To the business man, the second of these objects is paramount; and code-makers have constantly endeavored to express an increasing amount of information in a given number of letters.

At the present time, thanks to the fact that the world works in the information space with a large amount of information, it has become one of the most important measures for that, in a short time, for a short period of time. Therefore, for informing the world, only one computer connection became insufficient, it is very important to expand the connection through mobile devices, to use and develop mobile applications. Necessary information technologies for the integration of mobile communications are actively developing. This article discusses the widespread use of mobile applications for the development of mobile communications and their classification by structure and composition. Consider the features

Abstract In listening and reading, the foreign language learner must be able to process a tremendous amount of information in a short time. In order to do this, he must develop a strategy for choosing those items that help in recovering that information. One way of doing this is to concentrate on focal words: words containing key elements of meaning in the sentence. These words may then be used - in speech and writing - to reconstruct the original message. This paper explores the relationship of focel words to other sentence elements and describes various focal word exercises for listening and reading.

The article is devoted to the problem of finding productive pedagogical and psychological techniques that help to structure a large amount of information in a short time. As a solution to this issue, it is proposed to use methods of mnemotechnics for students to master complex biological material. The paper presents the results of a study by the authors, which showed that the most difficult for students of the course of cytology are associated with a large amount of memorization units, and the most effective technique used to study this topic is the letter code.

Every powerful critical idea is the product of a particular interpretive situation: we could even say, with considerable simplification, that it is the product of a prejudice. Every cultural moment develops its own critical myth (or prejudice), and reasons and interprets within the limits of this horizon. Often it needs only a short time for the myth to wither, the prejudice to decay; we realize that its claims, born of a particular historical perspective and valid only in part, were too high, and that it was not content to accept only this partial validity.But when a critical myth fades away, not everything is doomed to disappear. There are still positive traces, still a residual value which, once appropriately adjusted and corrected, can be recuperated. To achieve this, a more powerful interpretive system must arise which absorbs the error within a new perspective. Whatever survives the testing may become a new instrument of interpretation, perhaps one destined to last forever – or at least for a little longer (this is how progress is made).

To develop questionnaire and physical examination instruments that could be used by researchers and clinicians to undertake a detailed baseline assessment of professional orchestral musicians. METHODS: The final instruments were based on a combination of areas of interest to the musicians, areas of interest to the investigators, evidence-based approaches, and approaches in common use and so likely to have standardised results that can be used for comparison. RESULTS: The questionnaire content and length were found to be acceptable to the subjects. There did not appear to be any major problems with the subjects' interpretation of the questions. Most subjects found the physical examination protocol of suitable length, although some found it physically demanding. The multiple assessors were able to apply the protocol in a suitably standardised fashion and within an acceptably short time for use in large-scale studies. CONCLUSIONS: The questionnaire and physical examination protocol should prove useful to researchers working with professional musicians and provide a sound basis for the development of similar instruments by other researchers.

If we make a set of measurements, such as narrow-band or multicolour photo-electric measurements, which are designed to improve a scheme of classification, and in particular if they are designed to extend the number of dimensions of classification, i.e. the number of classification parameters, then some important problems of analytical procedure arise. First, it is important not to reproduce the errors of the classification scheme which we are trying to improve. Second, when trying to extend the number of dimensions of classification we have little or nothing with which to test the validity of the new parameters.Problems similar to these have occurred in other areas of scientific research (notably psychology and education) and the branch of Statistics called Multivariate Analysis has been developed to deal with them. The techniques of this subject are largely unknown to astronomers, but, if carefully applied, they should at the very least ensure that the astronomer gets the maximum amount of information out of his data and does not waste his time looking for information which is not there. More optimistically, these techniques are potentially capable of indicating the number of classification parameters necessary and giving specific formulas for computing them, as well as pinpointing those particular measurements which are most crucial for determining the classification parameters.

AbstractReplication failures were among the triggers of a reform movement which, in a very short time, has been enormously useful in raising standards and improving methods. As a result, the massive multilab multi-experiment replication projects have served their purpose and will die out. We describe other types of replications – both friendly and adversarial – that should continue to be beneficial.

AbstractWe present an analysis of short time-scale intensity variations in the coronal green line as obtained with high time resolution observations. The observed data can be divided into two groups. The first one shows periodic intensity variations with a period of 5 min. the second one does not show any significant intensity variations. We studied the relation between regions of coronal intensity oscillations and the shape of white-light coronal structures. We found that the coronal green-line oscillations occur mainly in regions where open white-light coronal structures are located.

We have studied the destruction of rabbit muscle actin filaments by osmium tetroxide (OSO4) to develop methods which will preserve the structure of actin filaments during preparation for transmission electron microscopy.Negatively stained F-actin, which appears as smooth, gently curved filaments in control samples (Fig. 1a), acquire an angular, distorted profile and break into progressively shorter pieces after exposure to OSO4 (Fig. 1b,c). We followed the time course of the reaction with viscometry since it is a simple, quantitative method to assess filament integrity. The difference in rates of decay in viscosity of polymerized actin solutions after the addition of four concentrations of OSO4 is illustrated in Fig. 2. Viscometry indicated that the rate of actin filament destruction is also dependent upon temperature, buffer type, buffer concentration, and pH, and requires the continued presence of OSO4. The conditions most favorable to filament preservation are fixation in a low concentration of OSO4 for a short time at 0°C in 100mM sodium phosphate buffer, pH 6.0.

A New High Excitation Objective Lens (Second-Zone Objective Lens) was discussed at Twenty-Sixth Annual EMSA Meeting. A new commercially available Transmission Electron Microscope incorporating this new lens has been completed.Major advantages of the new instrument allow an extremely small beam to be produced on the specimen plane which minimizes specimen beam damages, reduces contamination and drift.
