Previous work on the theoretical study of the intensity distribution in the emission spectrum of ScO is now extended and a comparison is made with some experimental spectrometric data, and some physical results such as the temperature of emission and the 'spin allowed' property of the A2Π → X2Σ transition are given and discussed. The great influence of the slight spin decoupling of the A2Π (case (a)) state on the intensity distribution is shown and is explained theoretically using the mixing coefficients obtained in a former rotational study of the spectrum.

Existing Data

The term “halogen molecule” is intended to include the interhalide compounds as well as the elementary molecules. The existence of three of the ten possible molecules of this type, namely, IF, BrF, and CIF, has not yet been established, and we have not attempted any spectroscopic search for them. For F 2 the data are meagre, only an emission spectrum being known, and we have therefore confined our attention to the other six molecules, namely, CI 2 , Br 2 , I 2 , BrCl, ICI, and IBr. The spectra of these, with the exception of BrCl, have been extensively investigated, and partially interpreted. There are certain features, however, notably the continua and diffuse bands observed in emission, which have not yet been satisfactorily explained, and we have set out to survey the existing data systematically and, where necessary, to obtain new data with the object of accounting for these features. The problem of obtaining satisfactory data of continua and diffuse bands is definitely different from that involved in the case of line and ordinary band spectra. Not only is it more difficult to make accurate visual settings for the purpose of wave-length determinations, but it becomes of much more importance to record the intensity distribution, which is often very characteristic and undoubtedly significant. For these reasons we have thought it essential to obtain and reproduce microphotometer records in all experiments, and to determine wave-lengths solely from these records. Quite low dispersion has been used, and appears very suitable for a general survey, although a more detailed investigation using higher dispersion may well prove profitable later. It seemed important to us to get strictly comparable data in all observations, and it has therefore been necessary to redetermine some of the existing data, which although numerous are seldom complete or homogeneous. A number of entirely new data are also presented. Some consideration must first be given to the known band systems of these molecules, since they provide evidence relating to the location and characteristics of molecular levels, some at least of which may be expected to be concerned in the emission of the continua and diffuse bands.

Collision Angle

Many researchers have studied the energy dissipation characteristics of two-jet collisions in air, but few have studied the related spatial rainfall distribution characteristics. In this paper, in combination with a model experiment and theoretical study, the spatial distributions of rainfall intensity of two-jet collisions, with different collision angles and flow ratios, are systematically studied. The experimental results indicated that a larger collision angle corresponds to a larger rainfall intensity distribution. The dimensionless maximum rainfall intensity sharply decreased with the flow ratio, while the maximum rainfall intensity slightly increased when the flow ratio was greater than 1.0. A theoretical equation to compute the location of maximum rainfall intensity is presented. The range of rainfall intensity distribution sharply increased with the flow ratio. When the flow ratio was greater than 1.0, the range of longitudinal distribution slightly increased, whereas the lateral distribution remained unchanged or slowly decreased. A formula to calculate the boundary lines of the x-axis is proposed.

Comparison With Experimental Data

A theoretical study of thin fluid film flows between rotating and stationary disks is presented. Inertia terms are included using an averaged method. It is assumed that inertia effects do not influence the shape of velocity profiles. The model is validated by comparison with experimental data and previous theoretical studies. A ThermoElastoHydroDynamic analysis of a hydrostatic seal is performed. The great influence of inertia terms on leakage rate prediction is shown.

Scientific Article

The article is focused on theoretical study of the principles of introduction of the institution of mediation in public law disputes in Ukraine. It has been determined that the introduction of mediation in the field of public administration should be carried out in accordance with the specifics of public law disputes. The current status of legal regulation of mediation in Ukraine has been analyzed. It has been emphasized that the main way to introduce the institution of mediation in resolving public law disputes is to create and continuously improve the administrative and legal regulation of mediation. The emphasis has been placed on the great influence of the principles of the mediation procedure on further formation of legal regulation of mediation. The article is focused on theoretical study of the principles of legal regulation of mediation as an element of the content of administrative and legal regulation of the social and legal institution of mediation, it considers scientific approaches to the concept of administrative and legal regulation and forms of its own definition. Administrative and legal regulation of mediation in the study has been understood as the purposeful influence of the state, its agencies and officials on relations arising in the field of mediation, in order to achieve stability, law and order through the use of legal means (legal norms, legal principles, legal facts, etc.) for establishing the extent of possible and necessary behavior of mediation subjects. The article illustrates the division of principles as legal means of administrative and legal regulation of mediation into general and special ones. The general principles of regulation of mediation in the administrative process correspond to the principles of administrative law. The basic principles of such regulation are the principles of the rule of law, legality, justice, priority of human and civil rights and freedoms, humanism, equality, non-discrimination, responsibility of the individual and the state, publicity, compliance with international standards, minimum state intervention, proportionality, etc.; the essence of each principle has been also clarified. Further research on the issues of the scientific article should be aimed at the possibility of practical application, implementation and realization of the principles of administrative and legal regulation of mediation.
