Miniature and model stone vessels of the Old Kingdom - Fromtypology to social and political background

Lucie Vendelová Jirásková - Miniature and model stone vessels of the Old Kingdom - From typology to social and political background Abstract The present dissertation thesis proposes a new systematic research in stone model and miniature vessels, which were used in the burial context in the Old Kingdom. The scope of work encompasses the limits of typology towards the social and political history. A detailed study of the preserved assemblages of stone model and miniature vessels and their characteristics in the context of the production and distribution of stone vessels in the Old Kingdom shows their specific social meaning. The changes, which can be detected on the assemblages, either from the point of view of their morphology or material, clearly point to particular key periods of social and political changes, which influenced the production and distribution of stone vessels, either in the miniature and model forms, or in the form of large size functional pieces.

Theory and Interpretation of Solar Decimetric Radio Bursts
Bárta, Miroslav ; Karlický, Marian (advisor)
Theory and Interpretation of Solar Decimetric Radio Bursts (doctoral thesis) Miroslav Bárta 2002 Abstract Solar radio emission represents an important source of direct information about many physical processes related to particle acceleration in the solar atmosphere. Namely, the radio bursts - intense and highly variable component of solar radio radiation - bear many signatures of underlying physics related to primary energy release in solar flares and eruptions. Indeed, decimetric (dm) radio bursts and their careful analysis provide the closest observational insight into the region of magnetic reconnection and the particle acceleration sites. On the other hand, emission mechanisms of solar dm radio bursts are typically non-thermal, involving various plasma micro-instabilities and wave-mode transformations. High non-linearity of the radio emission process thus put strong demands on correct physical interpretation of the observed bursts and on finding the relations between observed features (e.g., intensity, frequency profile and its dynamics) and underlying physics. This doctoral thesis addresses two particular areas of research in the solar radio bursts and their utilization in the flare plasma diagnostics: (1) Physical interpretation of two particular classes of radio bursts related to solar flares, and,...

The tomb of Unisankh at Saqqara and Chicago
Onderka, Pavel ; Bárta, Miroslav (advisor) ; Bareš, Ladislav (referee)
In 1908, Edward E. Ayer (1841-1927),1 the founding father of the Egyptian collection of the Field Museum of Natural History in Chicago, IL, purchased for the museum two chapels of Old Kingdom mastabas once located in the vicinity of the pyramid complex of Netjerykhet at central Saqqara. One of them belonged to Netjeruser (NTr-wsr),2 a high official from the later reign of Nyuserre till that of Menkauhor,3 the other to Unisankh (Wnjs-anx.w), who is generally considered to have been son of Unis, the last king of the Fifth Dynasty. The tomb of Unisankh was excavated in 1907 by James E. Quibell (1867-1935),4 then the chief inspector at Saqqara, for the purpose of its sale to the Field Columbian Museum in Chicago (the later Field Museum of Natural History).5 When Quibell started his excavations, the whole Unis Cemetery North- West was hidden under sand. In the course of excavating the site, Quibell cleared the tomb of Unisankh. He undoubtedly realized the existence of several other structures, in particular the tomb of Iynefert that was partly unearthed in the course of dismantling the neighboring tomb of Unisankh. One block from the mastaba of queen Nebet (Nbt), wife of Unis, was found as well.6

The Pyramid Complex of King Djoser - its placement in time and space
Koráb, Lenka ; Bárta, Miroslav (advisor) ; Krejčí, Jaromír (referee)
The pyramid complex of Djoser (Netjerikhet) who was a ruler of the 3rd Dynasty is considered to be a fundamental and unique set of buildings in the context of ancient Egyptian archaeology. The aim of the bachelor thesis is to present a comprehensive view of the archaeological form of the pyramid complex itself and its individual parts (Step pyramid, South tomb, South court, Heb-sed court, house of the south, house of the north, mortuary temple, serdab, enclosure wall etc.). Emphasis will also be put on the historical-religious situation that dwelled in Egypt during the 3rd Dynasty.

The Social Context of Copper in Ancient Egypt down to the end of Middle Kingdom
Odler, Martin ; Bárta, Miroslav (advisor) ; Altenmüller, Hartwig (referee) ; Lehner, Mark Edward (referee)
1 Odler, Martin 2020: The social context of copper in Ancient Egypt down to the end of Middle Kingdom. PhD thesis. Prague: Charles University, Faculty of Arts. Supervisor: Prof. Mgr. Miroslav Bárta, Dr. Abstract The subject of the doctoral thesis is a reconstruction of the chaîne opératoire of copper in ancient Egypt from its earliest occurrence in the fourth millennium BC until the end of the Middle Kingdom. As copper was the metal most widely used in ancient Egyptian society, its study can offer statistical "big data" otherwise rarely available for ancient cultures. Three large groups of sources are discussed successively: written and iconographic sources, archaeological sources (material culture, i.e. artefacts), and archaeometallurgical sources, divided into several consecutive stages of the chaîne opératoire. Copper was named bjA and read [byr] in the periods under study, while an interpretation as arsenical copper with a low and high content of arsenic, respectively, is proposed for so- called Asian copper and Hsmn. In the Middle Kingdom, the term Hsmn begun to be used also for tin bronze. The word for crucible was bD(.t) and the word for metalworker (incorporating both metallurgists and smiths) was bD.ty. There is no substantial Egyptian evidence from the periods under study for the current...

The social role and meaning of jewels in the Old Kingdom
Kovalovská, Soňa ; Bárta, Miroslav (advisor) ; Janák, Jiří (referee)
This work offers a view into the representation and function of the jewellery in the Old Kingdom. We can consider jewellery as a part of the cultural values of mankind, not only because of its aesthetic function. My purpose is a comprehensive insight of the importance and the representation of jewellery in the Old Kingdom, which is associated with a social role of the tomb owners. The primary source of knowledge of the meanings and functions of the jewellery are the iconographic sources in the Old Kingdom nonroyal tombs, including the scenes of the jewellery workshops and jewels as part of the funerary equipment.

Magnetic reconnection in the solar wind
Enžl, Jakub ; Přech, Lubomír (advisor) ; Bárta, Miroslav (referee) ; Kulhánek, Petr (referee)
Magnetic reconnection is a fundamental process that changes magnetic field configuration and converts a magnetic energy to flow energy and plasma heating. It can be found in a plasma with frozen magnetic field lines at boundaries where different magnetic field topologies encounter each other and thin current sheets are created as it is typical in the solar wind. In the thesis, we have used spacecraft measurements of solar wind plasma and magnetic field to found magnetic reconnection exhausts. We analyze and compare them with theoretical predictions. The results of the statistical analysis oriented on re-distribution of the magnetic energy in reconnection showed that both a portion of the energy deposited into heat as well as the energy spent on an acceleration of the exhaust plasma increase with the magnetic shear angle in accord with the increase of the magnetic flux available for reconnection. Moreover, we identify unusual events in the solar wind; we found magnetic reconnection exhausts accompanied by one or two side jets and explained their possible causes.
