В статье описаны исследования почв первого участка питомника Уральского учебно-опытного лесхоза. Полевые работы осуществлялись в сентябре 2020 г. Исследования были начаты в связи с необходимостью составления проекта реконструкции питомника. В ходе почвенной съемки была заложена сеть из 22 точек исследования на площади 2,8 га. Схема размещения точек исследования приведена в статье. Всего было заложено 2 разреза, 8 полуразрезов, 12 прикопок. Описание морфологических признаков почвы заложен- ных разрезов также приводится в данной статье. Установлено, что средняя мощность пахотного горизон- та исследуемого участка составила 29,8 ± 1,4 см при минимальной мощности 18 см и максимуме 44 см. В точках исследования было отобрано 36 почвенных образцов в двух повторностях. Почва питомника была отнесена к типу дерново-подзолистые окультуренные и виду дерново-слабоподзолистые. По мощности пахотного слоя исследуемые почвы классифицированы как среднепахотные с признаками средне- и силь- ноокультуренных почв. В одном из заложенных разрезов было зафиксировано, что подзолистый горизонт полностью перепахан и даже в горизонте В видны следы трансформации. Во втором разрезе горизонт А2 вовлечён в пахотный слой не полностью, а подпахотный горизонт (А2В) имеет белесовато-бурую окраску. Исследования почв питомника Уральского учебно-опытного лесхоза будут продолжены в лаборатории ка- федры лесоводства УГЛТУ. На основании данных исследований планируется составить почвенную карту и оценить почвы питомника на предмет пригодности для выращивания декоративного и лесного поса- дочного материала. Работы по почвенной съемке на втором и третьем участках исследуемого питомника запланированы на лето 2021 г. Field work was carried out in September 2020. Research was begun in connection with the need to draw up a project for the reconstruction of the nursery. During the soil survey, a network of 22 study points was laid on an area of 2. 8 hectares. The diagram of study point displacement is given in the article. In total, 2 cuts, 8 half-cuts, 12 traps were laid. A description of the morphological signs of the soil of the laid sections is also given in this article. It was established that the average power of the arable horizon of the study site was 29.8 ± 1.4 cm, with a minimum power of 18 cm and a mac-simum of 44 cm. At the points of study, 36 soil samples in two repetitions were selected. The soil of the nursery was classifi ed as der-new-podzolic cultivated and sod-slightly podzolic. According to the capacity of the arable layer, the studied soils are classifi ed as medium-arable with signs of medium and highly cultured soils. In one of the laid cuts, it was recorded that the podzolic gori-umbrella was completely swamped, and even in horizon B there are signs of transfer. In the second section, the horizon А2 not involved in the arable layer by half, but the under-arable horizon (А2В) has a whitish-brown color. Soil studies of the nursery of the Ural Educational and Experimental Forestry will be continued in the laboratory of the Department of Forestry of USFEU. Based on these studies, it is planned to draw up a soil map and evaluate the nursery soils for suitability for growing ornamental and forest planting material. Soil survey work on the WTO and the third section of the studied nursery is planned for the summer of 2021.

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.

Resonance Relation

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.

Letter Sound

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.

General Linguistic

As a general index of language development, the recall of first through fourth order approximations to English was examined in four, five, six, and seven year olds and adults. Data suggested that recall improved with age, and increases in approximation to English were accompanied by increases in recall for six and seven year olds and adults. Recall improved for four and five year olds through the third order but declined at the fourth. The latter finding was attributed to deficits in semantic structures and memory processes in four and five year olds. The former finding was interpreted as an index of the development of general linguistic processes.

Two experiments investigated the information conveyed by intonation from speaker to listener. A multiple-choice test was devised to test the ability of 48 adults to recognize and label intonation when it was separated from all other meaning. Nine intonation contours whose labels were most agreed upon by adults were each matched with two English sentences (one with appropriate and one with inappropriate intonation and semantic content) to make a matching-test for children. The matching-test was tape-recorded and given to children in the first, third, and fifth grades (32 subjects in each grade). The first-grade children matched the intonations with significantly greater agreement than chance; but they agreed upon significantly fewer sentences than either the third or fifth graders. Some intonation contours were matched with significantly greater frequency than others. The performance of the girls was better than that of the boys on an impatient question and a simple command which indicates that there was a significant interaction between sex and intonation.
