Great Mortality

The aim of this article was to describe how were plagues and illnesses perceived by the authors of the Liber Pontificalis. In the first part circumstances in which the first draft of the Liber Pontificalis was composed were analysed. Attention was given particularly to disadvantages that affected the population of Italy in the 6th century. The second part was devoted to plagues recorded in the Liber Pontificalis. When dealing with the plague the authors of the Liber Pontificalis used several terms like: pestilentia, clades, mors. Usually plagues were presented as caused by natural factors, but there was also a fragment attributing the eruption of the pestilence to divine disfavor. The third part was concerned with diseases that had affected individuals. The majority of cases where  diseases were mentioned in the Liber Pontificalis referred to the health of the popes. In the collection of papal biographies there were also descriptions of diseases that had affected other people: an emperor, bishop, soldier, clerk. Some of the illnesses appeared terminal but all of them affected the person`s life.

In Gaoyao Region in Guangdong Province there are several gatherings of Eight-trigram form, which are extremely consistent with Eight-trigram pattern. Over the years, some scholars, as well as in the official publicity materials, hold that these gatherings are created based on the concept deriving from Taiji and Eight-trigram Thinking. However, after research on several typical Eight-trigram form gatherings, the author holds that the Eight-trigram form is only external manifestation of the gathering, it also has more important intrinsic causes. The first is the adaptability to natural factors, followed by defense considerations, and the third is the social organizational forms.

The investigations described in this series of papers were partly experimental and partly observational. The first two papers will deal with the experimental work, and the third with the observational. The observational work has shown that Microtus agrestis has a definite breeding season in the British Isles, extending roughly from March till September. This species appeared to be a suitable one on which to experiment for the purpose of finding the factors which control the breeding season, a subject on which so little is known in any mammal. Our immediate object has been to find the factors, and not to find how they work. There seem to be two sorts of way in which they might work. Firstly, one could imagine that it might be physiologically impossible for an animal like Microtus to breed below a certain temperature, or in the absence of a certain foodstuff. There is, however, a second, quite different way in which such factors might act. It is possible that during the course of evolution Microtus might have evolved an adaptive response of stopping and starting reproduction when the temperature and food altered with the seasons beyond certain limits. One could imagine the natural selection of the offspring of those individuals which responded to the environment by breeding only at the most appropriate time for the rearing of the young. In our preliminary investigations we have not attempted to distinguish between these two possible modes of action of factors controlling the breeding season. Our object has been to find the factors, irrespective of the way in which they work. We have regarded the problem from the biological rather than the physiological point of view. No doubt we could stop Microtus from breeding by depriving it of vitamin E, or subjecting it to extremes of temperature ; but our experiments were planned in such a way that our animals were never subjected to unnatural conditions. They were never fed on unnatural foods, nor kept at higher or lower temperatures than occur naturally in Great Britain, nor given longer or shorter periods of light, nor more intense light. We were not anxious simply to stop and start the reproduction of Microtus at will, but to find what are the natural factors which control its breeding season in a state of nature.

In the course of several 21-cm observing programmes being carried out by the Leiden Observatory with the 25-meter telescope at Dwingeloo, a fairly complete, though inhomogeneous, survey of the regionl11= 0° to 66° at low galactic latitudes is becoming available. The essential data on this survey are presented in Table 1. Oort (1967) has given a preliminary report on the first and third investigations. The third is discussed briefly by Kerr in his introductory lecture on the galactic centre region (Paper 42). Burton (1966) has published provisional results of the fifth investigation, and I have discussed the sixth in Paper 19. All of the observations listed in the table have been completed, but we plan to extend investigation 3 to a much finer grid of positions.

The paper presents a summary of the results obtained by C. J. Cohen and E. C. Hubbard, who established by numerical integration that a resonance relation exists between the orbits of Neptune and Pluto. The problem may be explored further by approximating the motion of Pluto by that of a particle with negligible mass in the three-dimensional (circular) restricted problem. The mass of Pluto and the eccentricity of Neptune's orbit are ignored in this approximation. Significant features of the problem appear to be the presence of two critical arguments and the possibility that the orbit may be related to a periodic orbit of the third kind.

AbstractClosed expressions for the first, second, and (in some cases) the third moment of atomic transition arrays now exist. Recently a method has been developed for getting to very high moments (up to the 12th and beyond) in cases where a “collective” state-vector (i.e. a state-vector containing the entire electric dipole strength) can be created from each eigenstate in the parent configuration. Both of these approaches give exact results. Herein we describe astatistical(or Monte Carlo) approach which requires onlyonerepresentative state-vector |RV> for the entire parent manifold to get estimates of transition moments of high order. The representation is achieved through the random amplitudes associated with each basis vector making up |RV>. This also gives rise to the dispersion characterizing the method, which has been applied to a system (in the M shell) with≈250,000 lines where we have calculated up to the 5th moment. It turns out that the dispersion in the moments decreases with the size of the manifold, making its application to very big systems statistically advantageous. A discussion of the method and these dispersion characteristics will be presented.

Probe Size

A small electron probe has many applications in many fields and in the case of the STEM, the probe size essentially determines the ultimate resolution. However, there are many difficulties in obtaining a very small probe.Spherical aberration is one of them and all existing probe forming systems have non-zero spherical aberration. The ultimate probe radius is given byδ = 0.43Csl/4ƛ3/4where ƛ is the electron wave length and it is apparent that δ decreases only slowly with decreasing Cs. Scherzer pointed out that the third order aberration coefficient always has the same sign regardless of the field distribution, provided only that the fields have cylindrical symmetry, are independent of time and no space charge is present. To overcome this problem, he proposed a corrector consisting of octupoles and quadrupoles.

Turkish dermatologist, H. Beheet described the disease as recurrent triad of iritis, oral aphthous lesions and genital ulceration. Auto immune disease is the recent focus on the unknown etiology which is still being discussed. Among the other immunosupressive drugs, CyA included in it's treatment newly. One of the important side effects of this drug is gingival hyperplasia which has a direct relation with the presence of teeth and periodontal tissue. We are interested in the ultrastructure of immunocompetent target cells that were affected by CyA in BD.Three groups arranged in each having 5 patients with BD. Control group was the first and didn’t have CyA treatment. Patients who had CyA, but didn’t show gingival hyperplasia assembled the second group. The ones displaying gingival hyperplasia following CyA therapy formed the third group. GMC of control group and their granules are shown in FIG. 1,2,3. GMC of the second group presented initiation of supplementary cellular activity and possible maturing functional changes with the signs of increased number of mitochondria and accumulation of numerous dense cored granules next to few normal ones, FIG. 4,5,6.

The effects of training in letter-sound correspondences and phonemic decoding (segmenting and blending skills) on three kindergartners' word recognition abilities were examined using a single-subject multiple-baseline design across behaviors and subjects. Whereas CVC pseudowords were trained, generalization to untrained CVC pseudowords, untrained CVC real words, untrained CV and VC pseudowords, and untrained CV and VC real words were assessed. Generalization occurred to all of the untrained constructions for two of the three subjects. The third subject did not show the same degree of generalization to VC pseudowords and real words; however, after three training sessions, this subject read all VC constructions with 100% accuracy. Findings are consistent with group training studies that have shown the benefits of decoding training on word recognition and spelling skills and with studies that have demonstrated the effects of generalization to less complex structures when more complex structures are trained.
