The article is devoted to the unknown prayer to St. John Damascene preserved on the margins of the oldest Russian 12th century copy of the “Theology” by this Orthodox thinker. Its text is badly damaged and almost not readable. It has been visualized by the multispectral method with subsequent digital processing and published in this work. The text of the prayer was written in a unique type of ligature writing, which has only survived in one more codex. On the basis of codicological, paleographic and historical data, both texts have been dated to the last third of the 14th century and localized in Moscow. The article puts forward a hypothesis about the connection of the unusual ligature writing with the metropolitan scriptorium at the Moscow Chudov Monastery where there were Greek manuscripts at that time and new translations of liturgical texts were underway. Its appearance was probably due to the need of creating a new book letter design instead of the “ustav” (majuscule) in order to speed up the scribe’s work and save parchment. The original solution was inspired by the Greek ligature script and minuscule. However, this artificial style of writing did not spread out; the “ustav” was soon replaced by the “poluustav” letter form.

The earliest books in the early Piast state in the second half of the 10th century were likely imported from the Benedictine scriptoria in Bavaria, Saxony, Rhineland, and Lorraine. These manuscripts contained Biblical texts and liturgical books indispensible for celebrating the Mass. The 12th-century precepts determining the establishment of new Cistercian cloisters necessitated the parent monastery to provide the monks delegated to the new coenobium with at least nine basic and indispensible books: the Missal, the Epistolary, the Gospels, the Gradual, the Antiphonary, the Hymnal, the Psalter, the Lectionary, and the Calendar. The said regulations rendered the work of copyists particularly important. One testament to the weight of the Cistercian cloister scribes was their exemption by the General Chapter from other monastic duties performed for their respective monasteries, coupled with dispensation from prescribed rest in favor of additional work (if so required). Apart from the reproduction of liturgical texts and memorative libri vivorum et mortuorum, the Cistercian scriptoria also saw the edition of the running administrative and economic records of a given monastery. Working in the silence of the scriptorium, monks would edit the cloistral yearbooks, obituaries, monastery chronicles, and rhymed epitaphs. They contained notes of daily life outside the enclosure, the names and functions of individual friars, notes of watershed events taking place away from the monastery, and mentions of natural disasters (floods, fires, epidemics) in the surrounding areas, along with the incurred losses. The surviving monastery chronicles provide invaluable insight to the sensibilities and interpersonal relations of cloistered communities, as well as their relations with the immediate surroundings, and manifestations of medieval worldviews.

The orthodox liturgy was finally established during the 8th and 9th centuries. The two stepbrothers and eminent Byzantine poets St. Cosmas of Maiuma and St. John of Damascus greatly contributed to its development. They composed the majority of the irmi and troparia that are still performed during the liturgy today. During their lives, however, worshippers were facing certain difficulties in understanding the meaning of church odes. This is also true today when orthodox liturgy occasionally becomes an obstacle on the path to God for the worshippers. Greater efforts are also required in order to understand the liturgy and this is not always easy. One of the reasons for this is an incorrect translation of many odes into Russian and Slavonic. Comments from 12th century Byzantine writers and poets can help us clarify their meaning. Gregory of Corinth and his 23 commentaries on the liturgical canons are particularly noteworthy. In the current article, a philological analysis is conducted of two complex, “obscure” and unclear passages from the Canon of Pentecost. At the same time, Metropolitan Gregory’s exegeses of these extracts, which can help us better understand the meaning not only of these passages but also of the whole celebration, are cited.

The article was written to illustrate the difficulties we encounter when at­tempting to convey the biography of Aelred, a famous 12th century English abbot of Rievaulx. The difficulties are linked with the fact that Aelred lived in medieval times and his biography was written in the form of a hagiography. This style of writing was very popular in the middle ages and usually served to emphasize the holiness of a person’s life, i.e. to demonstrate an exemplary life of Christian vir­tues rather than as an attempt to concentrate on biographical details. The latter ra­ther served as points of reference to the person in question and were expressed in hagiographic style, i.e. with focus on models of behavior, achievements and mira­cles that fit the style, based on examples taken from the Bible and the lives of other popular saints. Written in monastic circles, such works took on the form of biogra­phies of saints and were often written to satisfy a specific cause (T.J. Heffernan). This is the type of biography we are dealing with here. When attempting to con­vey Aelred’s biography in the contemporary meaning of the term, we must first sift through its hagiographic form and supplement information contained therein with other historical and literary sources. In our case, the attempt was carried out in six points, with focus on: the primary source of Aelred of Rievaulx’s biography, Vita Aelredi (1); its author, Walter Daniel (2); the reasons why this work was writ­ten (3); its hagiographic form (4); the work’s internal sources, i.e. sources linked with the author’s own circles (5); as well as outside historical and literary sources of information concerning Aelred (6).

INTRODUCTION.- The physical properties of rock masses are greatly influenced by their internal discontinuities, like pores and fissures. So, these need to be measured as a basis for interpretation. To avoid the basic difficulties of measurement under optical microscopy and analogic image systems, the authors use S.E.M. and multiband digital image processing. In S.E.M., analog signal processing has been used to further image enhancement (1), but automatic information extraction can be achieved by simple digital processing of S.E.M. images (2). The use of multiband image would overcome difficulties such as artifacts introduced by the relative positions of sample and detector or the typicals encountered in optical microscopy.DIGITAL IMAGE PROCESSING.- The studied rock specimens were in the form of flat deformation-free surfaces observed under a Phillips SEM model 500. The SEM detector output signal was recorded in picture form in b&w negatives and digitized using a Perkin Elmer 1010 MP flat microdensitometer.

We have assembled an image processing system for use with our high resolution STEM for the particular purpose of working with low dose images of biological specimens. The system is quite flexible, however, and can be used for a wide variety of images.The original images are stored on magnetic tape at the microscope using the digitized signals from the detectors. For low dose imaging, these are “first scan” exposures using an automatic montage system. One Nova minicomputer and one tape drive are dedicated to this task.The principal component of the image analysis system is a Lexidata 3400 frame store memory. This memory is arranged in a 640 x 512 x 16 bit configuration. Images are displayed simultaneously on two high resolution monitors, one color and one black and white. Interaction with the memory is obtained using a Nova 4 (32K) computer and a trackball and switch unit provided by Lexidata.The language used is BASIC and uses a variety of assembly language Calls, some provided by Lexidata, but the majority written by students (D. Kopf and N. Townes).

A relatively new entry, in the field of microscopy, is the Scanning X-Ray Fluorescence Microscope (SXRFM). Using this type of instrument (e.g. Kevex Omicron X-ray Microprobe), one can obtain multiple elemental x-ray images, from the analysis of materials which show heterogeneity. The SXRFM obtains images by collimating an x-ray beam (e.g. 100 μm diameter), and then scanning the sample with a high-speed x-y stage. To speed up the image acquisition, data is acquired "on-the-fly" by slew-scanning the stage along the x-axis, like a TV or SEM scan. To reduce the overhead from "fly-back," the images can be acquired by bi-directional scanning of the x-axis. This results in very little overhead with the re-positioning of the sample stage. The image acquisition rate is dominated by the x-ray acquisition rate. Therefore, the total x-ray image acquisition rate, using the SXRFM, is very comparable to an SEM. Although the x-ray spatial resolution of the SXRFM is worse than an SEM (say 100 vs. 2 μm), there are several other advantages.

Diffraction intensities from intermetallic compounds are, in the kinematic approximation, proportional to the scattering amplitude from the element doing the scattering. More detailed calculations have shown that site symmetry and occupation by various atom species also affects the intensity in a diffracted beam. [1] Hence, by measuring the intensities of beams, or their ratios, the occupancy can be estimated. Measurement of the intensity values also allows structure calculations to be made to determine the spatial distribution of the potentials doing the scattering. Thermal effects are also present as a background contribution. Inelastic effects such as loss or absorption/excitation complicate the intensity behavior, and dynamical theory is required to estimate the intensity value.The dynamic range of currents in diffracted beams can be 104or 105:1. Hence, detection of such information requires a means for collecting the intensity over a signal-to-noise range beyond that obtainable with a single film plate, which has a S/N of about 103:1. Although such a collection system is not available currently, a simple system consisting of instrumentation on an existing STEM can be used as a proof of concept which has a S/N of about 255:1, limited by the 8 bit pixel attributes used in the electronics. Use of 24 bit pixel attributes would easily allowthe desired noise range to be attained in the processing instrumentation. The S/N of the scintillator used by the photoelectron sensor is about 106 to 1, well beyond the S/N goal. The trade-off that must be made is the time for acquiring the signal, since the pattern can be obtained in seconds using film plates, compared to 10 to 20 minutes for a pattern to be acquired using the digital scan. Parallel acquisition would, of course, speed up this process immensely.

The slowscan and TV signal of the Philips SEM 505 and the signal of a TV camera attached to a Leitz fluorescent microscope, were digitized by the data acquisition processor of a Masscomp 5520S computer, which is based on a 16.7 MHz 68020 CPU with 10 Mb RAM memory, a graphics processor with two frame buffers for images with 8 bit / 256 grey values, a high definition (HD) monitor (910 × 1150), two hard disks (70 and 663 Mb) and a 60 Mb tape drive. The system is equipped with Imaging Technology video digitizing boards: analog I/O, an ALU, and two memory mapped frame buffers for TV images of the IP 512 series. The Masscomp computer has an ethernet connection to other computers, such as a Vax PDP 11/785, and a Sun 368i with a 327 Mb hard disk and a SCSI interface to an Exabyte 2.3 Gb helical scan tape drive. The operating system for these computers is based on different versions of Unix, such as RTU 4.1 (including NFS) on the acquisition computer, bsd 4.3 for the Vax, and Sun OS 4.0.1 for the Sun (with NFS).

Digital computers are becoming widely recognized as standard accessories for electron microscopy. Due to instrumental innovations the emphasis in digital processing is shifting from off-line manipulation of electron micrographs to on-line image acquisition, analysis and microscope control. An on-line computer leads to better utilization of the instrument and, moreover, the flexibility of software control creates the possibility of a wide range of novel experiments, for example, based on temporal and spatially resolved acquisition of images or microdiffraction patterns. The instrumental resolution in electron microscopy is often restricted by a combination of specimen movement, radiation damage and improper microscope adjustment (where the settings of focus, objective lens stigmatism and especially beam alignment are most critical). We are investigating the possibility of proper microscope alignment based on computer induced tilt of the electron beam. Image details corresponding to specimen spacings larger than ∼20Å are produced mainly through amplitude contrast; an analysis based on geometric optics indicates that beam tilt causes a simple image displacement. Higher resolution detail is characterized by wave propagation through the optical system of the microscope and we find that beam tilt results in a dispersive image displacement, i.e. the displacement varies with spacing. This approach is valid for weak phase objects (such as amorphous thin films), where transfer is simply described by a linear filter (phase contrast transfer function) and for crystalline materials, where imaging is described in terms of dynamical scattering and non-linear imaging theory. In both cases beam tilt introduces image artefacts.

Children 6 and 10 years of age and adults were asked how fast a toy car had to be to catch up with another car, the latter moving with a constant speed throughout. The speed change was required either after half of the time (linear condition) or half of the distance (nonlinear condition), and responses were given either on a rating scale (judgment condition) or by actually producing the motion (action condition). In the linear condition, the data patterns for both judgments and actions were in accordance with the normative rule at all ages. This was not true for the nonlinear condition, where children’s and adults’ judgment and also children’s action patterns were linear, and only adults’ action patterns were in line with the nonlinearity principle. Discussing the reasons for the misconceptions and for the action-judgment dissociations, a claim is made for a new view on the development of children’s concepts of time and speed.
