Stone objects from the territory of ancient city Orgame / Argamum. Preliminary results

The preliminary results of a survey of ancient Hermione (epichoric Hermion) are presented in this paper. The survey was conducted during three short campaigns over the period 2015–2017, and focused on the urban layout and development of the ancient city. Because the ancient city area more or less coincides with modern Ermioni, the investigation was mainly restricted to the documentation and analysis of architectural remains that were both still visible above ground and accessible. However, the report also includes a thorough re-evaluation of previous scholarship, taking into consideration remains that are no longer visible. The author identifies three questions of particular interest, relating to the exact location, extent, and potential relocation of the ancient city, and points to the lack of a coherent interpretation. On the basis of present data, the author proposes that Hermione was indeed relocated to a new site, less than 1 km away from its original position, in the early 3rd century BC, and highlights the urban, social, and religious consequences of such an event. However, pending further evidence, the suggested scenario remains a hypothesis.

The report presents the preliminary results of the work of the Polish-Moroccan expedition in the region of the ancient city Volubilis in 2018. The research carried out in Morocco aims to answer the question of the appearance and functioning of the border defence system of the province Mauritania Tingitana. The topic is not sufficiently developed in existing publications. Field research has provided new data and interesting field observations. Recognition of the human activity from the Roman period in the region has allowed us to collect interesting ceramic material for preliminary dating of the sites.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

AbstractThe records of sunspot number, sunspot areas and sunspot locations gathered over the centuries by various observatories are reanalysed with the aim of finding as yet undiscovered connections between the different parameters of the sunspot cycle and the butterfly diagram. Preliminary results of such interrelationships are presented.

Right Ascension

Several outstanding problems affecting the existing parallaxes should be resolved to form a coherent system for the new General Catalogue proposed by van Altena, as well as to improve luminosity calibrations and other parallax applications. Lutz has reviewed several of these problems, such as: (A) systematic differences between observatories, (B) external error estimates, (C) the absolute zero point, and (D) systematic observational effects (in right ascension, declination, apparent magnitude, etc.). Here we explore the use of cluster and spectroscopic parallaxes, and the distributions of observed parallaxes, to bring new evidence to bear on these classic problems. Several preliminary results have been obtained.

Preliminary results reported last year on the ion etching of tobacco mosaic virus indicated that the diameter of the virus decreased more rapidly at 10KV than at 5KV, perhaps reaching a constant value before disappearing completely.In order to follow the effects of ion etching on TMV more quantitatively we have designed and built a second apparatus (Fig. 1), which incorporates monitoring devices for measuring ion current and vacuum as well as accelerating voltage. In addition, the beam diameter has been increased to approximately 1 cm., so that ten electron microscope grids can be exposed to the beam simultaneously.

Detailed Nature

Ever since Habraken and Economopoulos first employed the term granular bainite to classify certain unconventional transformation products in continuously cooled steels, the term has been widely accepted and used, despite the lack of a clear consensus as to the detailed nature of the transformation products which constitute granular bainite. This paper presents the preliminary results of a TEM investigation of an 0.04 wt% C, copper-containing steel (designated HSLA-100). It is suggested that the term granular ferrite rather than granular bainite is a more accurate description of this multiphase reaction product.Figure 1 is a light micrograph of a sample which had been air-cooled from 900°C to room temperature. The microstructure is typical of that which has been termed granular bainite in the past and appears to consist of equiaxed ferritic grains together with other minor transformation products. In order to examine these structures in more detail, both continuously cooled and isothermally transformed and quenched materials have been examined with TEM. Granular bainite has been found in virtually all samples.
