The Subject

The subject of this article is to present the results of the analysis of the possibilities to create optimal third-degree Reference Graphs which may be used to model ICT networks. The first part discusses the causes for the interest in the subject of the thesis. Basic definitions and terms related to the analysed type of graphs describing ICT networks are given. The second part consists of the analysis of the possibilities to construct regular third-degree structures bases on the usage of one ring of the parameters typical for Reference Graphs. A method of conduct is presented and then used for checking the potential possibility to construct optimal graphs. In the subsequent chapter the results of analysis of the possibilities to create optimal third-degree graphs with a double ring is discussed. The paper is concluded by observations and conclusions resulting from the research.

The Subject

The ancient Egyptians were the first to use a wedding ring as a symbol of love and fidelity. Bands were usually made from grass or hemp and worn on the fourth finger of the left hand, which was believed to include the vein that led directly to the heart. The circular shape of the ring—with no beginning and no end—represented eternal love. Over the centuries, societies throughout the world adapted the tradition to fit their own cultures. It was once customary in the United States for only the bride to wear a ring, but this changed during and after the marriage boom that followed World War II. The number of men wearing wedding bands more than quadrupled, and today, double-ring marriage ceremonies are the norm. None of the men in the group had anticipated that “until death do you part” would occur so early in his marriage. After their wives died, what their wedding rings symbolized, and what should be done with them, was far from clear. One evening as the group settled in, Joe reached toward the center of the table to pick out his sub and bag of chips when one of us (Don) noticed something different about his left hand. “Joe, you took off your ring.” All eyes turned to Joe’s left hand. A strip of pale white skin that had been shielded from the sun for nearly twenty years circled the base of his fourth finger. Before that moment, the men had never discussed the subject of wedding rings. The prospect of dating again had compelled Joe to make the change. “It’s not that I’m interested in anyone in particular. In fact, even thinking about going out with someone right now is kind of overwhelming. But, damn, I don’t want to be lonely for the rest of my life. I hope that someday I’ll feel for someone else the way I felt for Joy.” Joe took off his ring because he wanted to believe that one day that time would come.

The Subject

Why did the length of the work day and work week decline in the nineteenth and early twentieth centuries? In this chapter, the author explores possible explanations for these declines, contrasting events and trends in Britain and America, including the activities of trade unions, employers, statutory legislation, and the workings of labor markets. Classical economists tended to support the position taken by many employers which was to resist both legislation on hours and the efforts of trade unions to reduce hours. In the few instances in which the Classical economists provided precise reasons for their view, they made assumptions about the manner in which hours enter a firm’s production function. These assumptions can be tested which is the subject of the subsequent chapter.

This article investigates the functioning of the metaoperator in the good sense of the word, which characterising words, abstracted characteristics of the subject (both animate and inanimate), and appearance. The second type includes utterances where the role of the metaoperator in the good sense of the word neutralises both common and individual negative connotations not included in the conceptual nexus of the word. This type lets the operator, on the one hand, release the individual negative connotations that have appeared in contemporary speech while, on the other hand, it de-ideologizes the lexeme. The article also demonstrates the results of an experiment made, first, to examine the potential possibility of axiological re-coding of any negative word, and second, to estimate a non-estimating word. The experiment gave positive results for both tasks, allowing the author to state that the naive axiology includes the entire world in its estimative perception. The idealised model of the world practically overlaps with the language worldview.

The Subject

THE germ of that which follows came into being many years ago in the days of my youth as a university instructor and assistant professor. It was generated by the then quite outspoken attitude of colleagues in the “exact sciences”; the sciences of which the subject-matter can be exactly weighed and measured and the force of its movements mathematically demonstrated. They assured us that the study of languages and literature had little or nothing scientific about it because: “It had no domain of concrete fact in which to work.” Ergo, the scientific spirit was theirs by a stroke of “efficacious grace” as it were. Ours was at best only a kind of “sufficient grace,” pleasant and even necessary to have, but which could, by no means ensure a reception among the elected.

Orbit Computation

In this paper an orbit computation program for artificial satellites is presented. This program is operational and it has already been used to compute the orbits of several satellites.After an introductory discussion on the subject of artificial satellite orbit computations, the features of this program are thoroughly explained. In order to achieve the representation of the orbital elements over short intervals of time a drag-free perturbation theory coupled with a differential correction procedure is used, while the long range behavior is obtained empirically. The empirical treatment of the non-gravitational effects upon the satellite motion seems to be very satisfactory. Numerical analysis procedures supporting this treatment and experience gained in using our program are also objects of discussion.

Rule: I'd like at this point to bring up the subject of cables and wireways around the telescope. We've touched upon this twice during previous sessions: the cable wrap up problem, the communications problem, and data multiplexing problem. I think we'll ask Bill Baustian if he will give us a brief run down on what the electrical run problems are, besides doubling the system every year.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

The Subject

The growth of Ag films deposited on various substrate materials such as MoS2, mica, graphite, and MgO has been investigated extensively using the in situ electron microscopy technique. The three stages of film growth, namely, the nucleation, growth of islands followed by liquid-like coalescence have been observed in both the vacuum vapor deposited and ion beam sputtered thin films. The mechanisms of nucleation and growth of silver films formed by ion beam sputtering on the (111) plane of silicon comprise the subject of this paper. A novel mode of epitaxial growth is observed to that seen previously.The experimental arrangement for the present study is the same as previous experiments, and the preparation procedure for obtaining thin silicon substrate is presented in a separate paper.

Extensive Damage

With the advent of the space age and the need to determine the requirements for a space cabin atmosphere, oxygen effects came into increased importance, even though these effects have been the subject of continuous research for many years. In fact, Priestly initiated oxygen research when in 1775 he published his results of isolating oxygen and described the effects of breathing it on himself and two mice, the only creatures to have had the “privilege” of breathing this “pure air”.Early studies had demonstrated the central nervous system effects at pressures above one atmosphere. Light microscopy revealed extensive damage to the lungs at one atmosphere. These changes which included perivascular and peribronchial edema, focal hemorrhage, rupture of the alveolar septa, and widespread edema, resulted in death of the animal in less than one week. The severity of the symptoms differed between species and was age dependent, with young animals being more resistant.

The interaction of electron beams with a large variety of materials for information storage has been the subject of numerous proposals and studies in the recent literature. The materials range from photographic to thermoplastic and magnetic, and the interactions with the electron beam for writing and reading the information utilize the energy, or the current, or even the magnetic field associated with the electron beam.
