This thesis comprehensively analyse the issue of legal protection of inanimate nature. The thesis analyses the legal protection of inanimate nature only by Czech law and the primary source of this thesis is the Act No 114/1992 Coll., on the Protection of Nature and Landscape. The thesis is divided into two parts. The first part of thesis focuses on the specific legal protection of particular elements of inanimate nature in the Czech Republic, such as caves, paleontological resources and mineral resources. In this part, thesis analysis how these elements are protected by the law and how effective this protection is in practice. The second part of thesis focuses on territorial protection legal tools in the context of inanimate nature protection in terms of both general and special legal tools. It analysis legal protection of significant landscape elements and landscape character as well as inanimate nature protection through regulation of specially protected areas including Natura 2000 European protected areas. In this context the attention is also paid to protection of inanimate nature elements as protected habitats of animals and plants and their importance for the conservation of biodiversity. In addition to the comprehensive analysis of legal protection of inanimate nature in the Czech Republic...

This study is focused on the flow through the uppermost part of the unsaturated zone in karstified areas. The information about distribution of transit times and chemical reactions taking place in the unsaturated zone is based on isotopic and chemical composition of cave dripwaters, precipitations and water caught by gravitation lysimeters. The water balance was calculated using measurements of intensity of dripwaters and amounts of water caught by lysimeters and rain gauges. The velocity of a hydraulic shockwave between monitored objects was also estimated according to the delay between significant precipitation event and dripwater intensity increase. The field study took place in the Němcova 1 cave in the northern part of Moravian Karst, near the village Suchdol. It was carried out during the hydrological year 2010/2011. The cave is about 13 m under the surface. The information about composition of overlaying rock above the cave was obtained using geoelectrical and electromagnetic measurements. Studied geological environment is built of 0.5 - 1.5 m of soil, 0.5 - 3.5 m of epikarst and a layer of massive limestone as thick as 10 m. About 70 to 90 % of dripwaters have residence time over 4 years. The distribution of transit time of younger water can be described using the exponencial model (well...

Glass beads comprise the most frequently found evidence of trade between southern Africa and the greater Indian Oceanbetween the 7th and 16th centuries AD.  In this thesis beads recovered from southern African archaeological sites are organized into series, based on morphology and chemical composition determined by LA-ICP-MS analysis.  The results are used to interpret the trade patterns and partners that linked eastern Africa to the rest of the Indian Ocean world, as well as interconnections between southern Africa andEast Africa.   Comprehensive reports on bead assemblages from several archaeological sites are presented, including: Mapungubwe, K2 and Schroda in the Shashe-Limpopo Basin; Chibuene in southern Mozambique; Hlamba Mlonga in eastern Zimbabwe; Sibudu Cave in KwaZulu-Natal, Kaole Ruins in Tanzania and Mahilaka in northwest Madagascar.  The conclusions reached show that trade relationships and socio-political development in the south were different from those on the East Coast and that changes in bead series in the south demonstrate it was fully integrated into the cycles of the Eurasian and African world-system.

This dissertation is a study of appetite in Plato’s Timaeus, Republic and Phaedrus. In recent research is it often suggested that Plato considers appetite (i) to pertain to the essential needs of the body, (ii) to relate to a distinct set of objects, e.g. food or drink, and (iii) to cause behaviour aiming at sensory pleasure. Exploring how the notion of appetite, directly and indirectly, connects with Plato’s other purposes in these dialogues, this dissertation sets out to evaluate these ideas. By asking, and answering, three philosophically and interpretatively crucial questions, individually linked to the arguments of the dialogues, this thesis aims to show (i) that the relationship between appetite and the body is not a matter of survival, and that appetite is better understood in terms of excess; (ii) that appetite is multiform and cannot be defined in terms of a distinct set of objects; and (iii) that appetite, in Plato, can also pertain to non-sensory objects, such as articulated discourse. Chapter one asks what the universe can teach us about embodied life. It argues that Plato, in the Timaeus, works with an important link between the universe and the soul, and that the account of disorder, irrationality and multiformity identifying a pre-cosmic condition of the universe provides a key to understanding the excessive behaviour and condition of a soul dominated by appetite. Chapter two asks why the philosophers of the Republic’s Kallipolis return to the cave, and suggests that Plato’s notion of the noble lie provides a reasonable account of this. By exploring the Republic’s ideas of education, poetry and tradition, it argues that appetite – a multiform and appearance oriented source of motivation – is an essential part of this account. Chapter three asks why Socrates characterizes the speeches of the Phaedrus as deceptive games. It proposes that this question should be understood in the light of two distinctions: one between playful and serious discourse and one between simple and multiform. It argues that the speeches of the Phaedrus are multiform games, and suggests that appetite is the primary source of motivation of the soul addressed, personified by Phaedrus.

Il lavoro si occupa dell'evoluzione diacronica del sito incastellato di Monte Copiolo (Italia, regione Marche, provincia di Pesaro e Urbino) tra X e XVI secolo. / The work deals with the diachronic evolution of the Monte Copiolo’s castle, in Montefeltro (Italy, Marche region, province of Pesaro and Urbino) between X and XVI century.

Hydrogeologic investigations were conducted on the drainage systems of an area of the Pennyroyal sinkhole plain of south central Kentucky. The degree of karstification of five area streams was studied to develop an understanding of the evolution of drainage as the landscape changes from a sandstone caprock plateau to a limestone sinkhole plain. The Chester Upland, capped by the Big Clifty Sandstone, possesses predominantly surface drainage and the Pennyroyal Plain, formed on Mississippian limestones, possesses considerable subsurface drainage. As the Chester Upland Escarpment retreats and surface streams are onto the limestones, the streams evolve to become subsurface streams. The five streams observed in the study (all flowing on limestones) demonstrated less karst development close to the Chester Escarpment and more karst development with increasing distance from the escarpment. Sediments derived from the escarpment and plateau blanket the stream beds thus perching the streams and preventing chemically aggressive water from forming karst solution features in the limestones. The streams farther away from the escarpment are removed from the sediment source and are therefore able to downcut into the limestone and invade the subsurface to become cave streams. Lithologic investigation of limestones exposed in stream beds revealed that minor resistant units can act to diminish downcutting and maintain short sections of surface flow. The stream investigated was not flowing on a perching layer, but instead was held on the surface by a stratigraphic control (spillover layer) that prevented subterranean stream invasion. Dye traces conducted on groundwater flow in the sinkhole plain revealed that the area drainage pattern is changing as surface streams invade the subsurface and that integration between drainage basins is taking place. Stream piracy and stream diversion are occurring in the subsurface causing alteration of the existing topographic drainage divides that developed before the surface streams invaded the subsurface. A general model is presented which shows the evolution of surface drainage to subsurface drainage, as the Chester Escarpment continues its northwestward retreat.

The Lower Ordovician El Paso Group is a >400-m-thick carbonate succession exposed in the Franklin Mountains, El Paso, Texas. The El Paso Group contains multiple breccias related to collapsed-paleocave systems. These breccias have been documented as having formed during the top-Lower Ordovician Sauk depositional supersequence lowstand. Evidence presented in this study suggests that cave formation may have been as much as 350 million years younger and related to Laramide oblique right lateral compression. Regardless of the timing of formation, the breccias mapped in this study are of collapsed paleocave origin based on breccia clast organization and matrix content. Speleogenetic models are compared against observations of breccia distribution by direct field observations and mapping on sub-meter airborne light detection and ranging or lidar data. Point vectors were defined for every point within study area to highlight subtle changes in outcrop erosional profile for mapping geological features directly on the lidar point cloud. In addition, spectral data from airborne photography and hyperspectral image analysis were used assist in geological contact definition. A digital outcrop model was constructed from 3D geologic mapping results from which spatial statistic were extracted and used to reconstruct collapsed paleocave breccia bodies. The resultant breccia geometries were compared against laser-scanned modern cave dimensions, from Devil's Sinkhole, Rocksprings, Texas, and used in analysis of conceptual models for cave formation. The breccias of the southern Franklin Mountains follow linear trends that closely match Riedel shear fracture patterns predicted from right-lateral oblique compression. Stress orientations that match right-lateral oblique compression in the Phanerozoic of the El Paso region are related to the Laramide orogeny. The relationship of observed structures and the orientation of collapse breccias may indicate that southern Franklin Mountain breccia bodies are the result of a solution-enhanced tectonic karst system. / text

Cryptographic hash functions are an important tool in cryptography to achieve certain security goals such as authenticity, digital signatures, digital time stamping, and entity authentication. They are also strongly related to other important cryptographic tools such as block ciphers and pseudorandom functions. The standard and widely used hash functions such as MD5 and SHA-1 follow the design principle of Merkle-Damgard iterated hash function construction which was presented independently by Ivan Damgard and Ralph Merkle at Crypto'89. It has been established that neither these hash functions nor the Merkle-Damgard construction itself meet certain security requirements. This thesis aims to study the attacks on this popular construction and propose schemes that offer more resistance against these attacks as well as investigating alternative approaches to the Merkle-Damgard style of designing hash functions. This thesis aims at analysing the security of the standard hash function Cellular Authentication and Voice Encryption Algorithm (CAVE) used for authentication and key-derivation in the second generation (2G) North American IS-41 mobile phone system. In addition, this thesis studies the analysis issues of message authentication codes (MACs) designed using hash functions. With the aim to propose some efficient and secure MAC schemes based on hash functions. This thesis works on three aspects of hash functions: design, cryptanalysis and applications with the following significant contributions: * Proposes a family of variants to the Damgard-Merkle construction called 3CG for better protection against specific and generic attacks. Analysis of the linear variant of 3CG called 3C is presented including its resistance to some of the known attacks on hash functions. * Improves the known cryptanalytical techniques to attack 3C and some other similar designs including a linear variant of GOST, a Russian standard hash function. * Proposes a completely novel approach called Iterated Halving, alternative to the standard block iterated hash function construction. * Analyses provably secure HMAC and NMAC message authentication codes (MACs) based on weaker assumptions than stated in their proofs of security. Proposes an efficient variant for NMAC called NMAC-1 to authenticate short messages. Proposes a variant for NMAC called M-NMAC which offers better protection against the complete key-recovery attacks than NMAC. As well it is shown that M-NMAC with hash functions also resists side-channel attacks against which HMAC and NMAC are vulnerable. Proposes a new MAC scheme called O-NMAC based on hash functions using just one secret key. * Improves the open cryptanalysis of the CAVE algorithm. * Analyses the security and legal implications of the latest collision attacks on the widely used MD5 and SHA-1 hash functions.
