The Middle Ages

AbstractThis paper addresses the changes and continuities within the wide range of cartographic practices that existed in the Middle Ages. Following introductory thoughts on methodological issues, the text focuses on three different types of maps, all of which represent the world in its entirety: schematic maps, world maps and nautical charts. Within different texts, as independent artifacts or as atlases, these maps were employed for diverse purposes, such as the representation of fundamental principles, of encyclopaedic knowledge or of nautical surveys. At least from the twelfth century on, the different genres existed side by side – with adjustments of content and form occurring in each. By relating spacial order and historical content medieval maps produce meaning and assert the significance of the knowledge they display. The literal and philosophical world-views they provide make them valuable sources in modern education.

In September 2021, 126 km of 6-10 kV power lines were surveyed in Altai Kray, Russia. The survey encompassed different types of habitat from pine forests to the foothills of Altai mountains. Out of 126 km, 27.94 km of power lines were equipped with bird-protection devices to prevent bird death from electrocution. We uncovered 515 cases of bird death on unsafe lines. Raptors make 21% and endangered species – 1.94%. The density of dead birds was equal to 5.6 ind./km of non-safe power lines, and of raptors – 1.18 ind./km. The observed damage to the ecosystem was estimated as 6.1 million of Rub (equal to $83 350 or € 73 600), and the damage calculated per one electric pole was 3 925 Rub. The estimation of the death rate of birds on the observed length of power lines through the whole migration and breeding seasons makes 8.63 ind./km. Approximation to the presumptive total length of bird unsafe power lines in the Altai Kray makes 50 700 birds possibly die every year in the region from April till October. The highest level of bird mortality was observed on power lines stretching through open undisturbed habitats (i.e. steppe biotope). We also noted 2.9 times higher mortality on push brace poles compared with intermediate ones for all species, and 4.9 times higher for raptors only.

Necessary And Sufficient

The Laplace transform of the extinction time is determined for a general birth and death process with arbitrary catastrophe rate and catastrophe size distribution. It is assumed only that the birth rates satisfyλ0= 0,λj> 0 for eachj> 0, and. Necessary and sufficient conditions for certain extinction of the population are derived. The results are applied to the linear birth and death process (λj=jλ, µj=jμ) with catastrophes of several different types.

Abstract We argue that Tomasello's account overlooks important psychological distinctions between how humans judge different types of moral obligations, such as prescriptive obligations (i.e., what one should do) and proscriptive obligations (i.e., what one should not do). Specifically, evaluating these different types of obligations rests on different psychological inputs and has distinct downstream consequences for judgments of moral character.

Complete Interpretation

Previous freeze fracture results on the intact giant, amoeba Chaos carolinensis indicated the presence of a fibrillar arrangement of filaments within the cytoplasm. A complete interpretation of the three dimensional ultrastructure of these structures, and their possible role in amoeboid movement was not possible, since comparable results could not be obtained with conventional fixation of intact amoebae. Progress in interpreting the freeze fracture images of amoebae required a more thorough understanding of the different types of filaments present in amoebae, and of the ways in which they could be organized while remaining functional.The recent development of a calcium sensitive, demembranated, amoeboid model of Chaos carolinensis has made it possible to achieve a better understanding of such functional arrangements of amoeboid filaments. In these models the motility of demembranated cytoplasm can be controlled in vitro, and the chemical conditions necessary for contractility, and cytoplasmic streaming can be investigated. It is clear from these studies that “fibrils” exist in amoeboid models, and that they are capable of contracting along their length under conditions similar to those which cause contraction in vertebrate muscles.

Different Cell Types

Various types of intermediate-sized (10-nm) filaments have been found and described in many different cell types during the past few years. Despite the differences in the chemical composition among the different types of filaments, they all yield common structural features: they are usually up to several microns long and have a diameter of 7 to 10 nm; there is evidence that they are made of several 2 to 3.5 nm wide protofilaments which are helically wound around each other; the secondary structure of the polypeptides constituting the filaments is rich in ∞-helix. However a detailed description of their structural organization is lacking to date.

Different Types

In polyethylene single crystals pairs of black and white lines spaced 700-3,000Å apart, parallel to the [100] and [010] directions, have been identified as microsector boundaries. A microsector is formed when the plane of chain folding changes over a small distance within a polymer crystal. In order for the different types of folds to accommodate at the boundary between the 2 fold domains, a staggering along the chain direction and a rotation of the chains in the plane of the boundary occurs. The black-white contrast from a microsector boundary can be explained in terms of these chain rotations. We demonstrate that microsectors can terminate within the crystal and interpret the observed terminal strain contrast in terms of a screw dislocation dipole model.

Fibers composed of different types of collagen cannot be differentiated by conventional electron microscopic stains. We are developing staining procedures aimed at identifying collagen fibers of different types.Pt(Gly-L-Met)Cl binds specifically to sulfur-containing amino acids. Different collagens have methionine (met) residues at somewhat different positions. A good correspondence has been reported between known met positions and Pt(GLM) bands in rat Type I SLS (collagen aggregates in which molecules lie adjacent to each other in exact register). We have confirmed this relationship in Type III collagen SLS (Fig. 1).

Investigation of the particulate matter contained in the water sample, revealed the presence of a number of different types and certain of these were selected for analysis.An A.E.I. Corinth electron microscope was modified to accept a Kevex Si (Li) detector. To allow for existing instruments to be readily modified, this was kept to a minimum. An additional port is machined in the specimen region to accept the detector, with the liquid nitrogen cooling dewar conveniently housed in the left hand cupboard adjacent to the microscope column. Since background radiation leads to loss in the sensitivity of the instrument, great care has been taken to reduce this effect by screening and manufacturing components that are near the specimen from material of low atomic number. To change from normal transmission imaging to X-ray analysis, the special 4-position specimen rod is inserted through the normal specimen airlock.
