2008-01-01

Full Text Available A floor mosaic's substrate is composed of a variety of preparatory layers of mortar built on natural levelled ground or on top of a previous pavement. Mosaics' substrates differ one from the other in number, thickness and nature of the mortar layers. In this sense, it has been considered relevant to state how these differences are related with historical period, geographical position, function of the pavements within the building, technology of the substrates. A number of floor mosaics' substrates of Hellenistic and Roman period from archaeological sites in Greece and Italy are under study. The stratigraphy of substrates is recorded in situ, and samples from each mortar layer are analysed in the laboratory by means of different techniques. Results obtained so far indicate that characteristics of the Roman substrates mortar layers are clearly dependant on their position in the substrate stratigraphy, whereas in the case of the Hellenistic substrates, characteristics of the mortar layers are less varying with the stratigraphic position. Furthermore results show that floor mosaics' substrates are different according to the function of the pavement in the building.

A full size TESSERA shade tolerant module has been made and was tested under various shadow conditions. The results show that the dedicated electrical interconnection of cells result in an almost linear response under shading. Furthermore, the voltage at maximum power point is almost independent of the shadow. This decreases the demand on the voltage range of the inverter. The increased shadow linearity results in a calculated increase in annual yield of about 4% for a typical Dutch house.

The Formation and Evolution of Tessera and Insights into the Beginning of Recorded History on Venus: Geology of the Fortuna Tessera Quadrangle (V-2)

Head, J. W.; Ivanov, M. A.

2010-01-01

Today, and throughout its recorded history, Venus can be classified as a "one-plate planet." The observable geological record of the planet comprises only the last 1/4 or less of its overall geologic history. As shown by many authors, it started with intensive deformation in broad regions to form tessera [1-6] during the Fortunian period of history [7]. The period of tessera formation quickly changed to numerous zonal deformational belts of ridges and grooves that were followed by emplacement of vast volcanic plains (shield plains, regional plains) [7,8]. During the final epoch of the geologic history of Venus, large but isolated centers of volcanism formed extensive fields of lavas, with tectonics concentrated within fewer very prominent rift zones [8,9]. The observable changes in intensity and character of volcanism and tectonics suggest progressive changes from thin lithosphere early in the geologic history to thick lithosphere during later epochs [6,10]. We have little idea of the character of the first 3/4 of Venus' history. So, what does the earliest period of recorded history tell us about the transition from the Pre-Fortunian to the Fortunian period and what insight does this give us into this earlier period?

Thermally and optically stimulated luminescence of early medieval blue-green glass mosaics

Energy Technology Data Exchange (ETDEWEB)

Galli, A. E-mail: anna.galli@mater.unimib.it; Martini, M.; Montanari, C.; Sibilia, E

2004-12-01

The preliminary results of a study related to luminescent mechanisms in glass mosaic tesserae are presented. The samples came from a medieval glass deposit found during archaeological excavations in the S. Lorenzo Church in Milan. Energy Dispersive X-rays Fluorescence (EDXRF) measurements were performed to obtain information on the elemental composition of the materials. Thermally Stimulated Luminescence (TSL, both conventional and wavelength resolved) and Optically Stimulated Luminescence (OSL) analyses allowed to get information about traps and luminescence centres. The observed luminescence characteristics were close to that of quartz, showing the presence of an easy to bleach trap (300 deg. C, 1.95 eV) and of a hard to bleach trap (350 deg. C, 2.20 eV); charge transfer phenomena, involving the low-temperature peaks have been observed. There is a strong indication that the easy to bleach traps are responsible for both OSL and TSL emission at 300 deg. C.

Full Text Available Mosaic floors of surviving buildings in Ostia have been mainly recorded in photographs. From 2008, Japanese research group carries out a project of 3d measuring of the whole structure of ancient Roman city Ostia using laser scanners, including its landscape, city blocks, streets, buildings, wall paintings and mosaics. The laser scanner allows for a more detailed analysis and a greater potential for recording mosaics. We can record the data of mosaics, which are described piece by piece. However it is hard to acquire enough high dense point cloud and the internal camera of the laser scanner produce low quality images. We introduce a possible technology of 3D recording of mosaics with high-quality colour information; SFM. The use of this technique permits us to create 3D models from images provided from a CCD camera without heavy and large laser scanners. We applied SFM system to different three types of the mosaics laid down on the floors of "the House of the Dioscuroi", "the Insula of the Muse" and "the House of Jove and Ganymede", and created high resolution orthographic images. Then we examined to compare these orthographic images with that are created from the point cloud data. As a result, we confirmed that SFM system has sufficient practical utility for the mosaic research. And we present how much of density of point cloud or ground resolution are required for the documentation of mosaics accurately.

Near Infrared Multispectral Mapping of Venus Supports the Hypothesis that Tessera Plateau Material was Formed in the Presence of Surface Water

The VIRTIS instrument on Venus Express observed surface thermal emission from the surface. Studies of 1020nm data showed that tessera plateaus, intensely tectonically deformed highlands that predate most other terrains, have significantly lower thermal emission than other highlands. Lower thermal emission could be due either to lower surface emissivity, supporting the hypothesis that tessera are analogous to continental crust on Earth, or to a bias of Magellan altimetry, which does not fully resolve the topographic relief of tessera terrain. To eliminate this ambiguity, we additionally investigate the spectral windows at 1100 and 1180nm. Data are reduced to surface emissivity using an atmospheric radiative transfer model to account for atmospheric scattering and absorption/emission. Magellan altimetry was used to model atmospheric column height and surface temperature. The model uses a binary (collision-induced) absorption coefficient for each window. It fits absolute radiance and gradient with surface elevation reasonably well, although there are indications that the assumed adiabatic temperature lapse rate is not appropriate globally. The 1100nm band has a relatively low signal-to-noise ratio at the latitudes of the tessera plateaus, but Alpha Regio is visible in both the 1020 and the 1180nm band. The difference in emissivity between Alpha and the adjacent corona Eve, which has a similar elevation as Alpha, is 3.6% at 1020nm, but only 2% at 1180nm. The altimetry bias equivalent to the 1020nm deviation is 230 m, while the equivalent is only 70m at 1180nm. An altimetry bias therefore cannot fully explain the observations, and there must be a real difference in emissivity. The observations are consistent with the hypothesis that Alpha Regio has a more felsic composition. The emissivity spectra of granites at Venus temperatures are lower than those of basalt at 1020nm, but the difference decreases or vanishes towards the 1180nm window. The most plausible explanation

Beyond Romanization: The creolization of food. A framework for the study of faunal remains from Roman sites.

Directory of Open Access Journals (Sweden)

Gillian Hawkes

1999-11-01

Full Text Available The effects of the Roman conquest of Britain and the ensuing processes of Romanization have been studied for many years. The historical background to the development of the theory of Romanization has been widely discussed elsewhere (see Hingley 1996. Haverfield’s (1906 treatment of the topic was a major landmark in this development. He considered that the Roman conquest was a ‘good’ thing as it brought civilisation to the ‘natives’ who, recognising the superiority of Roman culture, willingly embraced `Roman-ness`. The theory of Romanization was further refined by Millett (1990 in The Romanization of Britain. The assumption that underlies Millett’s model is that cultural artefacts which to archaeologists look ‘Roman’ were perceived in the same way in the past. But need this be so? This paper will concern itself with looking at new approaches to culture change, especially relating to food, following the Roman conquest in Britain. It will aim to suggest methods of applying these new approaches to faunal remains, which will enable us to evolve a more subtle understanding of food in the Roman period.

On The Roman Domination Stable Graphs

Full Text Available A Roman dominating function (or just RDF on a graph G = (V,E is a function f : V → {0, 1, 2} satisfying the condition that every vertex u for which f(u = 0 is adjacent to at least one vertex v for which f(v = 2. The weight of an RDF f is the value f(V (G = Pu2V (G f(u. The Roman domination number of a graph G, denoted by R(G, is the minimum weight of a Roman dominating function on G. A graph G is Roman domination stable if the Roman domination number of G remains unchanged under removal of any vertex. In this paper we present upper bounds for the Roman domination number in the class of Roman domination stable graphs, improving bounds posed in [V.

Greek and Roman thought had a profound influence upon Western medical practice. From the fall of the Greek civilization to the fall of the Roman, remarkable progress of our understanding of human anatomy and physiology occurred. Here we review the attempts of Greek and Roman thinkers to develop the first understanding of the pathophysiology of urolithiasis, its epidemiology, differential diagnosis of renal versus bladder stones, medications for both colic and prevention, the role of familial syndromes, and dietary management.

"Roman Baths" in Contemporary Spa Tourism

Directory of Open Access Journals (Sweden)

Vesna Merc

2005-07-01

Full Text Available The commercialisation of images and symbols from antiquity, so characteristic of Slovenia since its independence, has been reflected over the last decade in spa tourism as well. Since the great crises in the sixties, and especially since the eighties, fifteen Slovene natural health resorts have concentrated on developing wellness and activities programs. This change in orientation has been accompanied by renovations, an expansion of the water surfaces and capacities, and new wellbeing, wellness, spirituality and beauty programs. An analysis of Slovene spas, wellness centres and hotel web pages shows that they frequently offer rooms, usually saunas, which are imitations of the Roman baths. These rooms are usually called "Roman saunas", "Tepidarium", "Caldarium", and "Roman-Irish baths". At Terme Ptuj, Zdravilišče Laško, Šmarješke Toplice, Grand Hotel Palace in Portorož, and Terme Čatež, saunas have been built or renovated in the Roman style. This trend of Roman rooms is a novelty, less than a decade old in Slovenia. The first sauna with a Roman theme, a Roman-Irish bath, was opened in 1997 in the Health and Beauty Centre at Terme Čatež. Modern Roman saunas are very popular, found not only in Slovenia but also in other parts of Europe, especially Germany and Austria. Their popularity has spread from the areas formerly occupied by the Romans to other parts of world, for example the USA and the Republic of South Africa. An analysis of Slovene saunas and wellness centres reveals a well-established trend to recreate certain parts of the Roman baths. This is attempted not only through Roman-style decorations, but also through certain structures particular to the Roman baths, such as the caldarium, tepidarium, and in one case even a laconicum. The approach, however, is highly eclectic, blending Roman, Greek and, above all, modern elements. The purpose of such rooms is to increase the appeal of the spas, while their design is mostly based on

THE EVOLUTION OF ROMAN FRONTIER CONCEPT AND POLICY

Directory of Open Access Journals (Sweden)

George Cupcea

2015-03-01

Full Text Available The Roman power is, ideologically, infinite in time and space. Nevertheless, the Roman state had experienced a wide variety of territorial limits, evolving in time and space, more or less throughout a millennium. If at first the Roman state, limited to Rome metropolitan area, later to the Italian peninsula, was easily defensible, beginning with the heavy expansion, also came trouble. The Romans, always innovating, find solutions for the fortification of the contact zones with the Barbarians. The Roman frontier concept was fundamentally different from the modern one. If the defence of Roman possessions was obviously priority, the border should remain an open ensemble, allowing for the free circulation of people and goods, some of the fundamental Roman rights. The peak of Roman expansion, 2nd century A.D. brings also the maximum development of the Empire frontier. Dacia overlaps widely chronologically on this trend, this being one of the reasons for one of the most complex frontier system in the Empire.

How to romanize Korean characters in international journals

Sun Huh

2017-08-01

Full Text Available For editors and manuscript editors, the romanization of Korean characters is a topic that should be understood thoroughly, because Korean proper nouns have become more widely used worldwide due to phenomena such as Hallyu (the Korean wave. In this report, I describe the 2 major romanization systems used in Korea: the Korean government’s romanization system and the McCune-Reischauer system. I also describe the transliteration guidelines presented in a variety of reference styles, such as the CSE (Council of Science Editors, ACS (American Chemical Society, AMA (American Medical Association, APA (American Psychological Association, IEEE (Institute of Electrical and Electronics Engineers styles and the NLM (National Library of Medicine style guide. I found that 2 journals have adopted the Korean government’s romanization system, while 10 use the McCune-Reischauer system. Other journals do not specifically mention a romanization system. Editors should select a romanization system and use it consistently. When presenting a reference that includes romanized text, the journal’s house style should be followed, based on international reference citation styles. Chinese characters in documents published in Korea should be romanized according to the Korean pronunciation.

Full Text Available This paper is based on the study of Roman silver coins, from archaeological sites located in Roman Dacia and Pannonia. Initially centred on the record of hybrid silver coins, the paper expanded its analysis on counterfeit pieces as well in order to fully understand all problems of roman silver coinage from the 1stto the 3rd centuries AD.The new and larger area of research had more than one implications, coin distribution on the studied sites, influx of coin in the province, quantity of recorded counterfeited pieces being just some of them. Thus every situation was discussed in different chapters, first presenting the coins and the laws that protected them, the studied sites and the analyse of the silver coins on these sites, the general and compared situation between the provinces, interpretation of the counterfeited and hybrid pieces and finally, conclusions on the subject.All these tasks have been achieved one step at a time, each archaeological site providing precious data which piled up and was finally pressed in order to present the correct historical situation.

2011-01-01

This study deals with the characterization of mortars collected from bath complex of the Roman villa rustica from an archeological site near Mosnje (Slovenia). The mortar layers of the mosaics, wall paintings and mortar floors were investigated. A special aggregate consisting of brick fragments was present in the mortars studied. The mineralogical and petrographic compositions of the mortars were determined by means of optical microscopy, X-ray powder diffraction and FTIR spectroscopy. Analysis of aggregate-binder interfaces using SEM-EDS revealed various types of reactivity rims. In order to assess the hydraulic characteristics of the mortars, the acid-soluble fractions were determined by ICP-OES. Furthermore, the results of Hg-porosimetry and gas sorption isotherms showed that mortars with a higher content of brick fragments particles exhibited a higher porosity and a greater BET surface area but a lower average pore diameter compared to mortars lacking this special aggregate. - Highlights: → Mineral and microstructural characterizations of brick-lime mortars. → Hydraulic character of mortars in Roman baths complex. → Reaction rims were observed around brick fragments and dolomitic grains. → Higher content of brick particles yielded a higher BET surface area. → Addition of brick particles increased porosity and diminished pore size diameter.

THEMIS Global Mosaics

Science.gov (United States)

Gorelick, N. S.; Christensen, P. R.

2005-12-01

We have developed techniques to make seamless, controlled global mosaics from the more than 50,000 multi-spectral infrared images of the Mars returned by the THEMIS instrument aboard the Mars Odyssey spacecraft. These images cover more than 95% of the surface at 100m/pixel resolution at both day and night local times. Uncertainties in the position and pointing of the spacecraft, varying local time, and imaging artifacts make creating well-registered mosaics from these datasets a challenging task. In preparation for making global mosaics, many full-resolution regional mosaics have been made. These mosaics typically cover an area 10x10 degrees or smaller, and are constructed from only a few hundred images. To make regional mosaics, individual images are geo-rectified using the USGS ISIS software. This dead-reckoning is sufficient to approximate position to within 400m in cases where the SPICE information was downlinked. Further coregistration of images is handled in two ways: grayscale differences minimization in overlapping regions through integer pixel shifting, or through automatic tie-point generation using a radial symmetry transformation (RST). The RST identifies points within an image that exhibit 4-way symmetry. Martian craters tend to to be very radially symmetric, and the RST can pin-point a crater center to sub-pixel accuracy in both daytime and nighttime images, independent of lighting, time of day, or seasonal effects. Additionally, the RST works well on visible-light images, and in a 1D application, on MOLA tracks, to provide precision tie-points across multiple data sets. The RST often finds many points of symmetry that aren't related to surface features. These "false-hits" are managed using a clustering algorithm that identifies constellations of points that occur in multiple images, independent of scaling or other affine transformations. This technique is able to make use of data in which the "good" tie-points comprise even less than 1% of total

The aim of this study is to investigate the archaeological finds to enlighten the medical methods of treatments and operations applied in Balkans during Roman Period. Some independent local and regional find groups, taken from existing publications will be grouped together and a holistic point-of-view will be taken against medicine in Balkan Geography during Roman Period. Due to basic differences it contained, the data before Roman Period are excluded. Most of Greece and Aegean Islands are also excluded since the topic selected is "Medicine of Roman Period." Greece and Aegean Islands should be evaluated in another study in connection with West Anatolia which is closer than the Balkan Geography in terms of social relations. The spread of medical tools in Balkans during Roman Period is concentrated around military garrisons, and in settlements built around military pathways, and in settlements containing an amphitheater associated with gladiators. This spread is verified by the studies on Bulgaria in general. The data is also compatible with the assertion suggesting that the amount of application of pharmaceutical treatment increases when one moves away from the military centres.

Full Text Available Alors que les développements structuralistes et post-structuralistes ont favorisé la “textualisation” de la littérature médiévale, l’auteur suggère que la recontextualisation de la réception du roman médiéval passe par un retour aux manuscrits. Appliquée au manuscrit du Vatican, Regina Latina 1725, cette hypothèse de recherche révèle une technique de contrepoint que permet la juxtaposition de différents romans et dont, en dernier recours, le lecteur est toujours un peu juge.

Abdel Khalek, S.

2016-11-23

The ATLAS Roman Pot system is designed to determine the total proton-proton cross-section as well as the luminosity at the Large Hadron Collider (LHC) by measuring elastic proton scattering at very small angles. The system is made of four Roman Pot stations, located in the LHC tunnel in a distance of about 240~m at both sides of the ATLAS interaction point. Each station is equipped with tracking detectors, inserted in Roman Pots which approach the LHC beams vertically. The tracking detectors consist of multi-layer scintillating fibre structures readout by Multi-Anode-Photo-Multipliers.

Full Text Available Celtiberian metrology has scarcely been investigated until now, with the exception of coin weights. On the basis of measurements of pre-Roman mud bricks, a Celtiberian foot of 24 cm is proposed. With regard to weights, we can accept a module of 9 g for silver jewelry and some bronze coins; however, loom weights do not conform to any metrological system. Over time, Roman measures of length (as indicated by the dimensions of bricks, tiles and architectural monuments and weight were adopted.

Biopolitics rudiments in Roman Law

Full Text Available This article proposes a jurisprudential and philosophical reflection on Biopolitics in Roman Law, based on juridical figures such as sacred men, aliens, slaves and iustitium. Working at the edge of roman society, they represent a relation of inclusion or tolerance in a World centred on its citizens, which led to a state of exception or to integration modes of this marginality. Lessons for the present time can still be learned from this dynamic, when a new ius commune is proposed.http://dx.doi.org/10.14195/2183-1718_66_11

Full Text Available Les notes de lectures de Flaubert dans sa correspondance permettent de dégager deux types de romans historiques : le roman à sujet ancien, qui se doit, pour être vraisemblable, d'éloigner les personnages en réduisant la part d'explications psychologiques, et le roman à sujet contemporain, qui au contraire allie prise de distance (historique ou sociale et rapprochement (psychologique. Victor Hugo excellerait dans le premier mais pas dans le second. Quant à Flaubert, son obsession sera de réussir dans les deux.Flaubert’s reading notes in his correspondence allow us to identify two types of historical novels: the novel with an ancient subject, which, to be plausible, must keep characters at a distance and limit psychological explanations, and the novel with a contemporary subject which, on the contrary, both keeps aloof from historical or social questions and draws nearer to psychological questions. Victor Hugo excelled in the first but not in the second posture.  As for Flaubert, his obsession was be to be successful in both.

2011-01-01

Roman glasses that have been in the sea or underground for about 1800 years can serve as the independent “experiment” that is needed for validation of codes and models that are used in performance assessment. Two sets of Roman-era glasses have been obtained for this purpose. One set comes from the sunken vessel the Iulia Felix; the second from recently excavated glasses from a Roman villa in Aquileia, Italy. The specimens contain glass artifacts and attached sediment or soil. In the case of the Iulia Felix glasses quite a lot of analytical work has been completed at the University of Padova, but from an archaeological perspective. The glasses from Aquileia have not been so carefully analyzed, but they are similar to other Roman glasses. Both glass and sediment or soil need to be analyzed and are the subject of this analytical plan. The glasses need to be analyzed with the goal of validating the model used to describe glass dissolution. The sediment and soil need to be analyzed to determine the profile of elements released from the glass. This latter need represents a significant analytical challenge because of the trace quantities that need to be analyzed. Both pieces of information will yield important information useful in the validation of the glass dissolution model and the chemical transport code(s) used to determine the migration of elements once released from the glass. In this plan, we outline the analytical techniques that should be useful in obtaining the needed information and suggest a useful starting point for this analytical effort.

Systems considerations in mosaic focal planes

White, K. P., III

1983-08-01

Two key reasons for pursuing the development of mosaic focal planes are reviewed and it is shown that rapid frame repetition rate is the only requirement that can be solved no other way than through mosaic focal planes. With the view that spaceborne mosaic focal plane sensors are necessarily 'smart sensors' requiring a lot of onboard processing just to function, it is pointed out that various artificial intelligence techniques may be the most appropriate to incorporate in the data processing. Finally, a novel mosaic focal plane design is proposed, termed a virtual mosaic focal plane, in response to other system constraints.

The seamless image is a mosaic of Landsat 7 scenes; geographically-accurate with 30 and 15 meter resolutions. By using the OpenGIS Web Map Service (WMS) interface, any organization can use the global mosaic as a layer in their geospatial applications. Based on a trade study, an implementation approach was chosen that extends a previously developed WMS hosting a Landsat 5 CONUS mosaic developed by JPL. The WMS Global Mosaic supports the NASA Geospatial Interoperability Office goal of providing an integrated digital representation of the Earth, widely accessible for humanity's critical decisions.

Characterization of the Roman curse tablet

Science.gov (United States)

Liu, Wen; Zhang, Boyang; Fu, Lin

2017-08-01

The Roman curse tablet, produced in ancient Rome period, is a metal plate that inscribed with curses. In this research, several techniques were used to find out the physical structure and chemical composition of the Roman curse tablet, and testified the hypothesis that whether the tablet is made of pure lead or lead alloy. A sample of Roman Curse Tablet from the Johns Hopkins Archaeological Museum was analyzed using several different characterization techniques to determine the physical structure and chemical composition. The characterization techniques used were including optical microscopy, scanning electron microscopy (SEM), atomic force microscopy (AFM), and differential scanning calorimetry (DSC). Because of the small sample size, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and X-ray fluorescence (XRF) cannot test the sample. Results from optical microscopy and SEM, enlarged images of the sample surface were studied. The result revealed that the sample surface has a rough, non-uniform, and grainy surface. AFM provides three-dimensional topography of the sample surface, studying the sample surface in atomic level. DSC studies the thermal property, which is most likely a lead-alloy, not a pure lead. However, none of these tests indicated anything about the chemical composition. Future work will be required due to the lack of measures finding out its chemical composition. Therefore, from these characterization techniques above, the Roman curse tablet sample is consisted of lead alloy, not pure lead.

"Roman Pot" at the ISR

CERN Multimedia

CERN PhotoLab

1980-01-01

"Roman pots" are stainless steel containers, which can be moved from outside the vacuum chamber towards the beam. They house detectors which are conveniently at atmospheric pressure and can still be brought close to the limit of the circulating beam, to detect particles emanating at very small angles from the intersection of two colliding beams. Eifionydd Jones was the inventor of this device, highly successful at the ISR and now used again at the TOTEM experiment at the LHC. This particular Roman Pot, with a thickness of 0.2 mm, was built in 1980 for experiment R210 in intersection I-2, in preparation for proton-antiproton collisions in 1981. See also 7501065.

Putting Roman Dams in Context: a Virtual Approach

Science.gov (United States)

Decker, M. J.; Du Vernay, J. P.; Mcleod, J. B.

2017-08-01

Water resources and management have become a critical global issue. During the half-millennium of its existence, the Roman Empire developed numerous strategies to cope with water management, from large-scale urban aqueduct systems, to industrial-scale water mills designed to cope with feeding growing city populations. Roman engineers encountered, adopted, and adapted indigenous hydraulic systems, and left lasting imprints on the landscape of the Mediterranean and temperate Western Europe by employing a range of water technologies. A recent academic study has enabled the identification of remains of and references to seventy-two dams from the Roman era, constructed in Spain between the 1st and 4th century AD. Such unique heritage, without comparisons in the Mediterranean makes Spain an emblematic case study for the analysis of Roman hydraulic engineering and water management policies. Fifty dams have been located and detailed. The twenty-two outstanding, although identified on the ground, have not been able to be acceptably characterized, due in some cases to their being ruins in a highly degraded state, others due to their being masked by repairs and reconstructions subsequent to the Roman era. A good example of such neglected dams is the buttress dam of Consuegra , in Toledo province (Castilla-La Mancha). Dating to the 3rd - 4th century AD, the Dam of Consuegra, on the basin of the Guadiana, with its over 600 metres length and 4,80 metres height, is a remarkable case of Roman engineering mastery. It had a retaining wall upstream, numerous buttresses and perhaps an embankment downstream, of which no remains are left. The application of 3D digital imaging technique to create a high quality virtual model of such monuments has proved to be successful especially for the study of the technological aspects related its construction. The case study of the Roman dam of Muel (Zaragoza) has shown, in fact, as best practices in digital archaeology can provide an original and

Woman in Roman law: Subject or object of the law?

Directory of Open Access Journals (Sweden)

Bogunović Mirjana

2012-01-01

Full Text Available In Rome, legal status of woman and her factual possibilities of impact on public life were in serious discrepancy. General attitude of the legal status of woman in time of Romans is best shown by Papinian, 'In many provisions of our law, the position of woman is worse than of man (D.9.1.5.'. Every free Roman woman was considered a subject of law, according to classical Roman law. Nevertheless, there were extensive legislations that limited her legal and business capacity. Naturally, woman did not have legal personality in all periods of Roman state and her legal status was adjusted to the factual changes that had occurred in Roman society. What makes her position specific in Rome is progressive social role that did not exist in Greek-Asian world. From these previously mentioned views, which were confronting, it is possible to draw some doubts. Was woman really on the margins of political happenings, or was she an actual actor, even initiator, of some political events?.

Astronomy in towns? An archaeoastronomical approach to the Roman urbanism

Science.gov (United States)

Rodríguez-Antón, A.; Belmonte, J. A.; González-García, A. C.

2017-03-01

Although the final definition of Archaeoastronomy is still under debate, what is clear is that this discipline offers a different approach to the knowledge of ancient cultures than traditional archaeology has done so far. Archaeoastronomy considers the sky as an inseparabe part of the environment and thus an element of the transformed landscape with highly symbolic content. In the case of the Roman culture, the great colonizing activity involved continuous spatial transformations and the skyscape should be considered as a piece of the created urbanized spaces. For this reason, a number of fieldwork campaigns were conducted in several Roman cities across different regions of the ancient Roman Empire in order to study the configuration of those landscapes and the possible integration of the sky during the buiding processes. At the present, our group has the largest sample of orientations of Roman settlements so far, and here it is shown the preliminary results of an statistical analysis which may offer new answers to the various still open questions in Roman urbanism, often faced from conservative views.

The ecclesiastical situation of the first generation Roman Christians

Directory of Open Access Journals (Sweden)

A. B. du Toit

1997-12-01

Full Text Available Forming pan of a trilogy about the first generation Roman Christians, this anicle concentrates on the ecclesiastical aspect. From some scattered and relatively small groups, the numbers of Roman Christians increased markedly in the second half of the first century. According to Romans 16, Jewish Christians played a significant role in the initial period, although Gentile Christians were in the majority. Friction between these groups may have been a problem, but was not Paul's main concern. The Gentile Christians were mainly from a foreign background. Thus the first Christian community had a strongly cosmopolitan character. The plurality of house-churches was mainly due to practical factors, but social differentiation might have played a role. Meetings most probably took place in the ordinary rented apanments of insulae. Romans 16 renders a vivid picture of the leadership activities of Christian women and of Paul's enlightened position in this regard.

The Gate of Heaven: Revisiting Roman Mithraic Cosmology

Science.gov (United States)

Assasi, R.

2016-01-01

The definition and origins of Roman Mithraism remain highly problematic and controversial among modern scholars. The majority of research on Roman Mithraism focuses on interpreting the physical evidence because no considerable written narratives or theology from the religion survive. The most important Mithraic artifact is a repeated bull-slaying scene, which leaves no doubt that this figure conveys the core divine message of the cult. There is also another important Mithraic character that seems to be as important as the bull-slayer. This figure is a lion-headed man entwined by a snake. The author suggests that these figures represent the north ecliptic pole and argues for the importance of this astronomical reference in the Mithraic iconography and mythology. The author also demonstrates the possible relation of his proposed astrological model to the geocentric understanding of the axial precession around the ecliptic pole, where the Roman bull-slaying Mithras could be visualized in the form of a Mithraic constellation. This astrological model also is proposed to be the architectural design concept of Roman Mithraeum. The author also points to the core Christian symbols as possible contemporaneous parallels or derivatives of the Mithraic iconography and theology.

The term origo in Roman epigraphy

Directory of Open Access Journals (Sweden)

Rafael GONZÁLEZ FERNÁNDEZ

2012-03-01

Full Text Available It is sometimes very difficult to interpret the term origo, since it can refer to different elements such as birth, place of origin, family or tribe. From the Republican period the Romans used to include this type of information in their inscriptions after the mention of the name, although, curiously, they did not employ the term origo itself, but other forms of expression. In this work we suggest that in Roman epigraphy this term was used, from the end of the Second Century and during the first half of the Third Century A. D., mainly in the times of the Severan Dynasty.

Creating a provincial landscape: roman imperialism and rural change in Lusitania

Directory of Open Access Journals (Sweden)

J. C Edmondson

2010-02-01

Full Text Available SUMMARY: This paper suggests some general approaches and raises some problems in studying the impact of Rome on the rural landscape in Lusitania. It concentrates on three crucial ways in which the landscape was transformed under Roman rule: (a changes in the pattern of rural settlement; (b changes in the nature of land use and agrarian exploitation; and (c changes in the ways in which the inhabitants of Lusitania perceived and thought about their world. It argues that a synthesis is needed of archaeological evidence from across the province, so that the impact of Rome on rural settlemet patterns may be compared in differing environmental regions. Further intensive field survey should also help to resolve some current problems in reconstructing the pattern of Iron Age and Roman rural settlement. Increased collection and analysis of pollen samples, carbonised wood, seeds, agricultural implements and animal bones is needed to assess more precisely the extent to which the Romans caused major changes in the nature of land use and agrarian exploitation. When accounting for change, it is essential to consider a wide variety of factors and to remember that rural change continued to occur throughout the Roman period. Finally, it was in forcing the inhabitants of Lusitania to perceive their world in radically new ways that the Romans made a lasting impact on the provincial landscape. First, the Romans created broad ethnic identities for their opponents, ignoring the complex, highly fragmented ethnic and regional geography of the area. Then by dividing the region into clearly defined civitates, they forced the inhabitants of Lusitania to envisage the landscape in a very different manner than before. Finally, a series of rituals emphasising Roman power (the census, the holding of judicial assizes, and the activities of the provincial council regularly reinforced these radically new mental maps of the new Roman provincial landscape.

Roman mural green pigment painting fragments from three Roman sites in the north of the Roman province Germania Superior: Koblenz Stadtwald Remstecken (KOSR), Weißenthurm " Am guten Mann" (WEIS) and Mendig Lungenkärchen (MELU), dating from second and third centuries AD were analyzed. The experiments were performed nondestructively using synchrotron-based scanning macro-X-ray fluorescence (SR-MA-XRF), synchrotron-based scanning micro-X-ray fluorescence (SR-μ-XRF), synchrotron-based X-ray diffraction (SR-XRD) and Raman spectroscopy. Correlation between SR-MA-XRF, SR-μ-XRF elemental map distributions and optical images of scanned areas was mainly found for the elements Ca, Fe and K. With XRF, Fe and K were identified correlated with green pigment, but in samples from two sites, Mendig Lungenkärchen and Weißenthurm " Am guten Mann", also Cu was detected in minor concentration. The results of SR-XRD and Raman spectroscopy were limited to one sample from Weißenthurm " Am guten Mann". In this sample, green earth and calcium carbonate were identified by SR-XRD and, additionally, malachite by Raman spectroscopy.

The Contribution of Mosaic Variants to Autism Spectrum Disorder.

Science.gov (United States)

Freed, Donald; Pevsner, Jonathan

2016-09-01

De novo mutation is highly implicated in autism spectrum disorder (ASD). However, the contribution of post-zygotic mutation to ASD is poorly characterized. We performed both exome sequencing of paired samples and analysis of de novo variants from whole-exome sequencing of 2,388 families. While we find little evidence for tissue-specific mosaic mutation, multi-tissue post-zygotic mutation (i.e. mosaicism) is frequent, with detectable mosaic variation comprising 5.4% of all de novo mutations. We identify three mosaic missense and likely-gene disrupting mutations in genes previously implicated in ASD (KMT2C, NCKAP1, and MYH10) in probands but none in siblings. We find a strong ascertainment bias for mosaic mutations in probands relative to their unaffected siblings (p = 0.003). We build a model of de novo variation incorporating mosaic variants and errors in classification of mosaic status and from this model we estimate that 33% of mosaic mutations in probands contribute to 5.1% of simplex ASD diagnoses (95% credible interval 1.3% to 8.9%). Our results indicate a contributory role for multi-tissue mosaic mutation in some individuals with an ASD diagnosis.

Full Text Available De novo mutation is highly implicated in autism spectrum disorder (ASD. However, the contribution of post-zygotic mutation to ASD is poorly characterized. We performed both exome sequencing of paired samples and analysis of de novo variants from whole-exome sequencing of 2,388 families.

We study the Greek and Roman mythology using the network theory. We construct a directed network by using a dictionary of Greek and Roman mythology in which the nodes represent the entries listed in the dictionary and we make directional links from an entry to other entries that appear in its explanatory part. We find that this network is clearly not a random network but a directed scale-free network. Also measuring the various quantities which characterize the mythology network, we analyze t...

Full Text Available The Second Vatican Council (1962–1965 is regarded as one of the most significant processes in the ecumenical church history of the 20th century. At that time, a younger generation of Roman Catholic theologians began to make their mark in the church and within the ecumenical theological scene. Their work provided an ecumenical bridge between the Reforming and the Roman Catholic ecclesiastical traditions, notwithstanding the subsequent negative response of the Roman church hierarchy. Despite important advances, recent pontificates significantly altered the theological landscape and undermined much of the enthusiasm and commitment to unity. Roman Catholic theological dissent provided common ground for theological reflection. Those regarded as the ‘enemy within’ have become respected colleagues in the search for truth in global ecclesiastical perspective. This article will use the distinction between the history and the narratives of Vatican II.

Full Text Available We present three cases of trisomy 9 mosaicism diagnosed by amniocentesis with ongoing pregnancies after referral to our center due to fetal abnormalities. Two cases were associated with severe fetal growth restriction (FGR, each of which resulted in an intrauterine fetal demise (IUFD in the third trimester. The other case involved mild FGR with a congenital diaphragmatic hernia and resulted in a live birth with severe development delay. A major prenatal finding of trisomy 9 mosaicism is FGR. Fetuses with trisomy 9 mosaicism can rarely survive in the case of severe FGR.

On the acoustics of ancient Greek and Roman theaters.

Farnetani, Andrea; Prodi, Nicola; Pompoli, Roberto

2008-09-01

The interplay of architecture and acoustics is remarkable in ancient Greek and Roman theaters. Frequently they are nowadays lively performance spaces and the knowledge of the sound field inside them is still an issue of relevant importance. Even if the transition from Greek to Roman theaters can be described with a great architectural detail, a comprehensive and objective approach to the two types of spaces from the acoustical point of view is available at present only as a computer model study [P. Chourmouziadou and J. Kang, "Acoustic evolution of ancient Greek and Roman theaters," Appl. Acoust. 69, re (2007)]. This work addresses the same topic from the experimental point of view, and its aim is to provide a basis to the acoustical evolution from Greek to Roman theater design. First, by means of in situ and scale model measurements, the most important features of the sound field in ancient theaters are clarified and discussed. Then it has been possible to match quantitatively the role of some remarkable architectural design variables with acoustics, and it is seen how this criterion can be used effectively to define different groups of ancient theaters. Finally some more specific wave phenomena are addressed and discussed.

Healing Gods, Heroes and Rituals in the Graeco-Roman World

Full Text Available This editorial introduces the articles published within the OLH Special Collection, ‘Healing Gods, Heroes and Rituals in the Graeco-Roman World’. The first two articles in this collection interrogate the figures of specific healing gods. Olympia Panagiotidou’s article ‘Asclepius’ Myths and Healing Narratives: Counter-Intuitive Concepts and Cultural Expectations’ focuses on the curative features that defined the image of Asclepius, the most famous of the healing gods. The next article in the collection, ‘The Fate of a Healing Goddess: Ocular Pathologies, the Antonine Plague, and the Ancient Roman Cult of Bona Dea’ by Leonardo Ambasciano, interrogates the religious figure of another healing agent: the Italian goddess Bona Dea who was particularly venerated in Rome and in the region of Latium and whose cult reveals the way in which ancient Roman androcentric control over women was institutionalised through religious figures.  The third article in the collection, Audrey Ferlut’s ‘Goddesses as Consorts of the Healing Gods in 'Gallia Belgica' and the 'Germaniae': Forms of Cult and Ritual Practices’ considers the impact that cults dedicated to gods and goddesses had on populations in the wider area of the Roman Empire, focusing on the Northern provinces of the Western Roman Empire ('Gallia Belgica' and the 'Germaniae'. The collection’s final article, ‘From Textual Reception to Textual Codification: Thessalos and the Quest for Authenticity’ by Spyros Piperakis, moves the discussion from the question of cult practices to ‘alternative’ healing therapies in antiquity. Piperakis deals with astrological medicine, one of many alternative therapeutic methods that became popular during the Hellenistic and Roman period.  Taken together, the articles in ‘Healing Gods, Heroes and Rituals in the Graeco-Roman World’ demonstrate that we need to approach the study of ancient myths and cults within their socio-cultural context

Health Profiles of Mosaic Versus Non-mosaic FMR1 Premutation Carrier Mothers of Children With Fragile X Syndrome

Directory of Open Access Journals (Sweden)

Marsha R. Mailick

2018-05-01

Full Text Available The FMR1 premutation is of increasing interest to the FXS community, as questions about a primary premutation phenotype warrant research attention. 100 FMR1 premutation carrier mothers (mean age = 58; 67–138 CGG repeats of adults with fragile X syndrome were studied with respect to their physical and mental health, motor, and neurocognitive characteristics. We explored the correlates of CGG repeat mosaicism in women with expanded alleles. Mothers provided buccal swabs from which DNA was extracted and the FMR1 CGG genotyping was performed (Amplidex Kit, Asuragen. Mothers were categorized into three groups: Group 1: premutation non-mosaic (n = 45; Group 2: premutation mosaic (n = 41, and Group 3: premutation/full mutation mosaic (n = 14. Group 2 mothers had at least two populations of cells with different allele sizes in the premutation range besides their major expanded allele. Group 3 mothers had a very small population of cells in the full mutation range (>200 CGGs in addition to one or multiple populations of cells with different allele sizes in the premutation range. Machine learning (random forest was used to identify symptoms and conditions that correctly classified mothers with respect to mosaicism; follow-up comparisons were made to characterize the three groups. In categorizing mosaicism, the random forest yielded significantly better classification than random classification, with overall area under the receiver operating characteristic curve (AUROC of 0.737. Among the most important symptoms and conditions that contributed to the classification were anxiety, menopause symptoms, executive functioning limitations, and difficulty walking several blocks, with the women who had full mutation mosaicism (Group 3 unexpectedly having better health. Although only 14 premutation carrier mothers in the present sample also had a small population of full mutation cells, their profile of comparatively better health, mental health, and executive

Ritter, C L; Steele, M W; Wenger, S L; Cohen, B A

1990-01-01

Our finding of chromosome mosaicism with a ring 22 in a retarded black boy with hypomelanosis of Ito prompted a review of this "syndrome." Most patients have a variety of non-dermal defects, particularly those affecting CNS function. Among karyotyped patients, most are chromosome mosaics of one sort or another. Hypomelanosis of Ito turns out to be a causable non-specific phenotype, i.e., a clinical marker for chromosome mosaicism of all different types in individuals with a dark enough skin to show lighter patches. Consequently, cytogenetic evaluation is indicated in all patients with this skin finding.

Full Text Available The creation and cohesion of the Roman empire owed much to the spread of literacy through the provinces and the use of texts as an instrument of government. An important manifestation of this is the role of the written word in the Roman army, exemplified by the diplomas that granted Roman citizenship and other privileges to auxiliary soldiers on completion of their military service. Margaret Roxan, one of the Institute's honorary research fellows, has studied these diplomas for many years, and her achievement was honoured at an international conference in London in May 2002.

Change in silica sources in Roman and post-Roman glass

2003-01-01

Although Roman and post-Empire glasses found in Europe are reputed to have a very constant composition and hence source of components, it appears that some 4-5th century and later specimens show evidence of a different source of silica (sand) component. Zirconium and titanium are the discriminating elements. Data presented here for 278 specimens from 1st to 4th century German and Belgian samples indicate a strongly homogeneous Zr and Ti content; N: number of analyzed samples while 62 samples from Maastricht show low Zr-Ti contents from 1st to 3rd century samples while 4-5th century samples show a strong trend of concomitant Ti and Zr increase. If the high values of Zr-Ti represent a new source of silica (sand) the trend from low to high content suggests that a significant amount of low Zr-Ti glass was recycled to form these glass objects. Similar high Ti content can be seen in analysis results reported for other but not all 4-5th century samples found in northern Europe while earlier productions show typical low Ti contents. Although the fusing agent for these glasses seems to have always been natron (a mineral deposit in the Nile delta) from Hellenistic times to the 9th century, a change in the silica source, indicated by variation of the Ti and Zr content, could very well reflect the results of political instability of the 4-5th century exemplified by the fragmentation of the Roman Empire into two parts

Sex mosaics in a male dimorphic ant Cardiocondyla kagutsuchi

2009-01-01

Gynandromorphy, or the development of organisms with a combination of male and female morphological features, is common in Hymenoptera. The underlying mechanism is likely associated with the sex-determination system, and studying this phenomenon should lead to a deeper understanding of both embryonic development and sex determination. The reproductive capabilities of gynandromorphs (hereafter, sex mosaics) remain unclear. We studied gynandromorphy in the Malaysian ant Cardiocondyla kagutsuchi, which has sex mosaics of queens (gynandromorphs; mosaic of queens and winged male) and workers (ergatandromorphs; mosaic of worker and wingless ergatoid male). These sex mosaics were classified into seven morphological categories. Most individuals had more male than female body areas. Behavioral observations revealed that sex mosaics behave more in accordance with the “sex” of their brain than that of the reproductive organs (gaster). Relative DNA quantities showed that both female and male regions contained haploid and diploid nuclei, irrespective of their phenotypic appearance, indicating that external appearance did not reflect internal tissues. Nearly one third of the adults were sex mosaics and they were not infected with Wolbachia. Our results suggest that the production of sex mosaics in this species does not pose a substantial cost to colonies and that the underlying causes are therefore not strongly selected against.

Magnetic and electromagnetic prospections at the Roman city of Hadrianopolis, southern Albania

We report on a combined magnetic-GPR survey performed in 2015-2017 at the ancient Roman city of Hadrianopolis, located in southern Albania, in the context of the project Teatri Antichi Riuniti (TAU). The collected data supplemented previous archaeological surveys performed by the University of Macerata with the aim of promoting the valley and starting the realization of an archaeological park. Hadrianopolis was founded through a reorganization of a previous Hellenistic settlement. Starting from 2015, magnetic and GPR surveys were carried out in Hadrianopolis in order to determine the urban framework. The collected data revealed the existence of structures organized along two main different patterns, which have been interpreted as due to the superposition of Roman buildings and Late Antiquity structures. In fact, the arrangement of structures in the studied area shows a regular urban organization of Roman type separated by a less regular disposition of the buildings that can be attributed to the Byzantine age. The latter arrangement is superimposed on the previous Roman structures. A stone wall, clearly identified by the combination of magnetic anomalies and GPR images, separates the Byzantine seattlement from the genuine Roman sector.

Human parasites in the Roman World: health consequences of conquering an empire.

Science.gov (United States)

Mitchell, Piers D

2017-01-01

The archaeological evidence for parasites in the Roman era is presented in order to demonstrate the species present at that time, and highlight the health consequences for people living under Roman rule. Despite their large multi-seat public latrines with washing facilities, sewer systems, sanitation legislation, fountains and piped drinking water from aqueducts, we see the widespread presence of whipworm (Trichuris trichiura), roundworm (Ascaris lumbricoides) and Entamoeba histolytica that causes dysentery. This would suggest that the public sanitation measures were insufficient to protect the population from parasites spread by fecal contamination. Ectoparasites such as fleas, head lice, body lice, pubic lice and bed bugs were also present, and delousing combs have been found. The evidence fails to demonstrate that the Roman culture of regular bathing in the public baths reduced the prevalence of these parasites. Fish tapeworm was noted to be widely present, and was more common than in Bronze and Iron Age Europe. It is possible that the Roman enthusiasm for fermented, uncooked fish sauce (garum) may have facilitated the spread of this helminth. Roman medical practitioners such as Galen were aware of intestinal worms, explaining their existence and planning treatment using the humoural theory of the period.

Behavioral Variability and Somatic Mosaicism: A Cytogenomic Hypothesis.

Science.gov (United States)

Vorsanova, Svetlana G; Zelenova, Maria A; Yurov, Yuri B; Iourov, Ivan Y

2018-04-01

Behavioral sciences are inseparably related to genetics. A variety of neurobehavioral phenotypes are suggested to result from genomic variations. However, the contribution of genetic factors to common behavioral disorders (i.e. autism, schizophrenia, intellectual disability) remains to be understood when an attempt to link behavioral variability to a specific genomic change is made. Probably, the least appreciated genetic mechanism of debilitating neurobehavioral disorders is somatic mosaicism or the occurrence of genetically diverse (neuronal) cells in an individual's brain. Somatic mosaicism is assumed to affect directly the brain being associated with specific behavioral patterns. As shown in studies of chromosome abnormalities (syndromes), genetic mosaicism is able to change dynamically the phenotype due to inconsistency of abnormal cell proportions. Here, we hypothesize that brain-specific postzygotic changes of mosaicism levels are able to modulate variability of behavioral phenotypes. More precisely, behavioral phenotype variability in individuals exhibiting somatic mosaicism might correlate with changes in the amount of genetically abnormal cells throughout the lifespan. If proven, the hypothesis can be used as a basis for therapeutic interventions through regulating levels of somatic mosaicism to increase functioning and to improve overall condition of individuals with behavioral problems.

Full Text Available The archaeological traces of the Roman mining and metallurgy in eastern Serbia are rather frequent but insufficiently studied and published. Three mining-metallurgical regions abounding in gold, silver, copper, iron and lead could be distinguished there: 1. the upper course of the Pek river, metalla Pincensia, 2. the area between Bor, Zlot, Crna Reka and Rgotina and 3. the area in the river basin of Beli Timok, two latter ones had been organized as territoria metallorum. The archeometallurgical sites confirmed by investigations are: Kraku lu Jordan at the confluence of the Brodica river and the Pek river, Rudna Glava, Tilva Roš in Bor, Gamzigrad - Romuliana, Rgotina near Zaječar and Timacum Minus in the village Ravna near Knjaževac. Roman mining-metallurgical activities in eastern Serbia flourished from the end of the 3rd century, were interrupted by the invasion of Huns in AD 441. and restored in the time of emperors Anastasius and Justin I, in the end of the 5th - beginning of the 6th centuries. The Roman mining-metallurgical centers functioned in the 6th century until the Slav invasion in the beginning of the 7th century.

PIXE and XRF Analysis of Roman Denarii

2017-09-01

A set of Roman Denarii from the republican to the imperial period (140BC-240AD) has been studied using X-ray fluorescent (XRF) scanning and proton induced x-ray emission (PIXE) techniques. XRF and PIXE are commonly used in the study of cultural heritage objects because they are nondestructive. The combination of these two methods is also unique because of the ability to penetrate the sample with a broader spectrum of depths and energies than either could achieve on its own. The coins are from a large span of Roman history and their analysis serves to follow the economic and political change of the era using the relative silver and copper contents in each sample. In addition to analyzing the samples, the study sought to compare these two common analysis techniques and to explore the use of a standard to examine any shortcomings in either of the methods. Data sets were compared and then adjusted to a calibration curve which was created from the analysis of a number of standard solutions. The concentrations of the standard solutions were confirmed using inductively coupled plasma spectroscopy. Through this we were able to assemble results which will progress the basis of understanding of PIXE and XRF techniques as well as increase the wealth of knowledge of Ancient Roman currency.

Udayakumar, Achandira M; Al-Kindy, Adila

2013-12-01

Trisomy 8 mosaicism (Warkany syndrome) is a rare viable condition with variable phenotypes, ranging from mild dysmorphic features to severe malformations. Karyotyping and fluorescence in-situ hybridization potentially help detecting this low mosaic clone to confirm the diagnosis of patients with classical and unusual clinical presentations. This report reviews few previous cases to describe our case - a boy who had trisomy 8 mosaicism with severe dysmorphic features, born to a consanguineous Arabic couple. This study concludes that careful cytogenetic diagnoses of trisomy 8 mosaicism is essential for appropriate management and follow up of this rare disorder.

Tourist valorization of roman imperial city Felix Romuliana

2012-01-01

Full Text Available The tourism industry is a great potential for the development of Serbia. The main characteristics of the existing and potential tourist offer of Serbia are interesting and diverse natural resources and cultural and historical heritage. Felix Romuliana, established palace of the Roman emperor Galerius, is located in the valley of the Black Timok, near Zaječar and the village of Gamzigrad in eastern Serbia. The palace was built in the late third and early fourth century, as a testamentary construction. This is where the Roman emperor was buried and included among the gods. It is the best preserved example of Roman palatial architecture which in 2007 was added to the List of World Heritage of UNESCO. One of the key tasks of this paper is to point out ways of promoting and popularizing this tourism potential that can be used as a resource for the development of cultural tourism and as such strengthen the position of Serbia''s tourist offer in Europe. The aim of this paper is contained in the presentation of the site Felix Romuliana and extraction of the most important attractiveness through valorization, which on the bases of historical and cultural significance may be activated for tourism purposes.

Mortar from the Roman Colosseum and a Roman cistern from Albano Laziale were characterized with optical microscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and thermal analysis (differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA)). The different techniques provided consistent results that the mortar of the Colosseum is mainly calcareous lime, while the mortar of the cistern is pozzolanic siliceous material. The study highlights the capabilities of the different methods for the analysis of cement. For routine analysis XRD is adequate but for characterization of poorly crystalline phases FT-IR and TGA have definite advantages.

1988-01-01

A method has been established for determination of the crystal mosaic spread. The method is based on recording all neutron-reflected, under bragg condition, from a certain crystal plane. A computer code was developed especially in order to fit the measured wavelength's distribution of the reflected neutrons with the calculated one, assuming that the crystal mosaic spread has a Gaussian shape. The code accounts for the parameters of the time of flight spectrometer used during the present measurements, as well as divergence of the incident neutron beam. The developed method has been applied for determination of the mosaic spread of both zinc and pyrolytic graphite (P.G.) crystals. The mosaic spread values deduced from the present measurements, are 10'+-6' and 3.60 0 +-0.16 0 respectively for Zn and P.G. crystals

1. Leaf extracts of Sudan grass, Hippeastrum equestre Herb., lily, and Abutilon striatum Dicks. (A. Thompsoni hort.), each affected with its respective mosaic disease, and peach affected with yellows disease, were tested for their ability to precipitate antiserum for virus extract of tobacco mosaic disease. No precipitate occurred. 2. Nicotiana glutinosa L., N. rustica L., and Martynia louisiana Mill. were added to the list of hosts of tobacco mosaic virus which have been tested with antiserum for the same virus in N. tabacum L. var. Turkish. The object was to determine the presence or absence of material reacting with the specific precipitins such as that already demonstrated in extracts of tomato, pepper, and petunia affected with the same virus. The presence of specific substances was demonstrated in every case. 3. The viruses of ringspot and cucumber mosaic diseases were multiplied in Turkish tobacco and leaf extracts of the affected plants were used in turn as antigens in precipitin tests with antiserum for tobacco mosaic virus extract of Turkish tobacco. A slight precipitation resulted in the tubes containing undiluted antiserum and virus extract such as occurs when juice from normal tobacco is used with undiluted antiserum. No precipitate was demonstrable that was specific for virus extracts of tobacco affected with either ringspot or cucumber mosaic disease. 4. The results favor the interpretation that the specific antigenic substance in virus extract of tobacco mosaic disease is foreign antigenic material, possibly virus itself, not altered host protein.

Full Text Available Infection of viruses on Cucurbitaceae may cause high yield and economic losses. Squash mosaic virus is a seed borne virus and among the most important virus infecting Cucurbitaceae. The aims of these research was to detect infection of several viruses on Cucurbitaceae and to examine seed transmission efficiency of SqMV. Detection of Cucumber mosaic virus (CMV, Squash mosaic virus (SqMV, Watermelon mosaic virus-2 (WMV-2, Zucchini yellow mosaic virus (ZYMV, and Tobacco ringspot virus (TRSV from field samples and seeds was conducted using Indirect-ELISA method. Infection of CMV, SqMV and ZYMV was detected from field samples. Seed transmission of SqMV on commercial seeds of bottle gourd, watermelon, zucchini, cabocha, cucumber, and melon was 13, 13, 33, 73, 100, and 100%, respectively. Seed transmission of ZYMV was only occurred on bottle gourd and zucchini, i.e. 13.3% and 26.67%, respectively. Infection of SqMV through F2 seed was determined from cucumber, bottle gourd, and melon, i.e. 93, 100, and 100%, respectively. Therefore, the status of SqMV as quarantine pest should be evaluated since SqMV was already found in West Java.

The Roman Catholic position on abortion.

Science.gov (United States)

Barry, R

1997-01-01

This article presents the history and grounds of the official position of the Roman Catholic Church that abortion under any circumstances, including abortion to save the life of the mother, should be prohibited. After an introduction that deplores the lack of mercy shown to killers of abortionists while Catholic priests threatened by pro-abortion forces are not offered protection, the article traces the historic development of the Catholic abortion policy and rebuts arguments that abortion was permitted in the early Christian Church. The next section explains Catholic views on the personhood of a conceptus and refutes the contentions of Joseph Donceel that early abortion should be permitted because of uncertainty about the nature of the conceptus and the possibility of delayed animation. The fourth section of the paper debates the points raised by Susan Teft Nicholson who maintains that the Catholic position regarding abortion rests on the Church's animosity towards sexual pleasure. The paper goes on to criticize Nicholson's claims that the Roman Catholic position on abortion is inconsistent with the Church's own understanding of the Principle of Double Effect because the Church fails to allow abortion in many cases where it would be permissible under the Principle. Section 6 describes the underlying motive of the Roman Catholic Church's abortion position as an attempt to protect the innocent fetus from deliberate death and to justify the Church's application of protection from deliberate killing to those who are innocent of aggressive action. This discussion is followed by a justification of the Church's prohibition of abortion in cases of aggression, such as the aggression ascribed to a fetus when a pregnancy imperials the life of a mother. It is concluded that the US will likely legalize suicide and mercy killing as it has the killing of innocent fetuses who are probably ensouled with personhood and are not formal aggressors.

Comparative Comparison of City and Urbanism during Sassanid Period in Iran and the Ancient Roman

Zohre Moqimizade

2017-02-01

Full Text Available Sassanid replaced migrating nomads and tribes with urbanization system and concentration of population. Sassanid desire to increase the population was due to the fact that population is the core of urban systems and focus-oriented system. Sassanid tried marching to Syria and Asia Minor to gain population. Immigrant Roman population was accommodated in newly established cities. Romans had structured and deep thinking about urban development, such that their territory was made up of urban units which were connected through a system of roads and bridges. Romans innovation in urban development can be summed up in creating military cities. Sassanid urbanization after the Parthians was influenced by Roman urbanization which is most visible in the shape of Sassanid cities. In this study, while examining cities and urbanization in Sassanid reign and Roman Empire, their influence on each other and their similarities and differences in their urbanization methods were also investigated.

Full Text Available Based on Big Three referecing styles guides, namely APA, Chicago (Turabian and MLA Style, this study discusses the citation formats in which have been applied and specified for scholarly references in non-English languages, especially in Chinese language scholarly writing. This study targets on those Taiwan journals, indexed by TSSCI, THCI Core, A&HCI, SSCI and Scopus, that use the Romanization of references in Chinese journal. By analyzing their notes for contributors and the real situation of application in the Chinese cited works. In respect of the aforementioned three major referencing styles and the rules made by journals themselves, the findings are as follows: the APA, Chicago, and MLA Styles should be revised according to the practical needs of citing non-English references; academic journal publishers need to specify and provide the guidelines and templates of romanizing references in respect of contributed articles; international citation index databases providers should stipulate and provide their description style for romanizing references, and the government and major academic institutes should put more efforts to assist local scholarly journals to cope with the reference romanization problems, even at promoting a kind of consistent Pinyin principle for referencing styles for Chinese journal publishing in Taiwan.

Real-time image mosaicing for medical applications.

Science.gov (United States)

Loewke, Kevin E; Camarillo, David B; Jobst, Christopher A; Salisbury, J Kenneth

2007-01-01

In this paper we describe the development of a robotically-assisted image mosaicing system for medical applications. The processing occurs in real-time due to a fast initial image alignment provided by robotic position sensing. Near-field imaging, defined by relatively large camera motion, requires translations as well as pan and tilt orientations to be measured. To capture these measurements we use 5-d.o.f. sensing along with a hand-eye calibration to account for sensor offset. This sensor-based approach speeds up the mosaicing, eliminates cumulative errors, and readily handles arbitrary camera motions. Our results have produced visually satisfactory mosaics on a dental model but can be extended to other medical images.

Roman sophisticated surface modification methods to manufacture silver counterfeited coins

Ingo, G. M.; Riccucci, C.; Faraldi, F.; Pascucci, M.; Messina, E.; Fierro, G.; Di Carlo, G.

2017-11-01

By means of the combined use of X-ray photoelectron spectroscopy (XPS), optical microscopy (OM) and scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS) the surface and subsurface chemical and metallurgical features of silver counterfeited Roman Republican coins are investigated to decipher some aspects of the manufacturing methods and to evaluate the technological ability of the Roman metallurgists to produce thin silver coatings. The results demonstrate that over 2000 ago important advances in the technology of thin layer deposition on metal substrates were attained by Romans. The ancient metallurgists produced counterfeited coins by combining sophisticated micro-plating methods and tailored surface chemical modification based on the mercury-silvering process. The results reveal that Romans were able systematically to chemically and metallurgically manipulate alloys at a micro scale to produce adherent precious metal layers with a uniform thickness up to few micrometers. The results converge to reveal that the production of forgeries was aimed firstly to save expensive metals as much as possible allowing profitable large-scale production at a lower cost. The driving forces could have been a lack of precious metals, an unexpected need to circulate coins for trade and/or a combinations of social, political and economic factors that requested a change in money supply. Finally, some information on corrosion products have been achieved useful to select materials and methods for the conservation of these important witnesses of technology and economy.

The Roman-Irish Bath: Medical/health history as therapeutic assemblage.

Science.gov (United States)

Foley, Ronan

2014-04-01

The invention of a new form of hot-air bath in Blarney, Ireland in 1856, variously known in its lifetime as the Roman-Irish or Turkish Bath, acted as the starting point for a the production of a globalised therapeutic landscape. Tracking the diffusion of the Roman-Irish bath template from its local invention in Ireland to a global reach across the Victorian world and recognizing its place within a wider hydrotherapeutic history, this paper frames that diffusion as a valuable empirical addition to assemblage theory. The specific empirical history of the spread of the Roman-Irish/Turkish bath idea is drawn from primary archival and secondary historical sources. It is then discussed and, drawing from work on assemblage theory, analyzed against three broad themes: mobile networks, socio-material practices and contested emergence. The emergent relational geographies of the Roman-Irish Bath identify important roles for the diffusion and transformation of specific medical settings, identities and functions. These were linked in turn to competing social-healing pathways wherein bodies were technologically and morally managed, to produce a more inhabited form of therapeutic assemblage. In all cases the differential diffusion of the bath idea, it's shifting and fractured material forms and multiple inhabitations and discourses were contested and mobile and spoke to an assemblage approach which has ripe potential for exploration across a range of medical/health geography settings.

Laser cleaning on Roman coins

Science.gov (United States)

Drakaki, E.; Karydas, A. G.; Klinkenberg, B.; Kokkoris, M.; Serafetinides, A. A.; Stavrou, E.; Vlastou, R.; Zarkadas, C.

Ancient metal objects react with moisture and environmental chemicals to form various corrosion products. Because of the unique character and high value of such objects, any cleaning procedure should guarantee minimum destructiveness. The most common treatment used is mechanical stripping, in which it is difficult to avoid surface damage when employed. Lasers are currently being tested for a wide range of conservation applications. Since they are highly controllable and can be selectively applied, lasers can be used to achieve more effective and safer cleaning of archaeological artifacts and protect their surface details. The basic criterion that motivated us to use lasers to clean Roman coins was the requirement of pulsed emission, in order to minimize heat-induced damages. In fact, the laser interaction with the coins has to be short enough, to produce a fast removal of the encrustation, avoiding heat conduction into the substrate. The cleaning effects of three lasers operating at different wavelengths, namely a TEA CO2 laser emitting at 10.6 μm, an Er:YAG laser at 2.94 μm, and a 2ω-Nd:YAG laser at 532 nm have been compared on corroded Romans coins and various atomic and nuclear techniques have also been applied to evaluate the efficiency of the applied procedure.

Full Text Available The Ancient Egyptians were close observers of the heavenly bodies behavior from prehistoric times, which evidenced by the numerous astronomical tools and scenes they left. Throughout the Egyptian history, images of night sky decorated coffins, tombs, temples and some other different kinds of monuments. These images served as a theoretical and visual tribute to the solar cycle and bore strong renewing associations. This article investigates the function of the serpent within a various collection of ancient Egyptian zodiacs dating back to the Greco-Roman Period, which was readily incorporated into the existing tradition of astronomical iconography. In order to explain the adoption of the serpent, this article examines its role in the astronomical images. There are no actual evidences for serpent iconography found in ancient astronomical scenes before the Greco-Roman Period, I ample to prove that knowledge of those creatures existed from the earliest time, and pervade the Egyptian symbolism. The details of the serpent picture have sketched and valid for the Greco-Roman Egypt, starting from the Third Century B.C.

Literacy and recitation in the Roman Empire

Letícia Fantin Vescovi

2010-12-01

Full Text Available In our modern societies, the paradigm of reading is individual and silent. However, far from being the only one possible, this wasn’t even the main form of reading in the Ancient times. The text doesn’t exist outside its materiality, and, if the current standard is the printed object, it was, for a long time, a form of transmission connected to practices of orality. In the Roman world, the main form of circulation of the literary text was the recitation, which happened in various ways: public or private recitations, literary contests where the text was judged from an oral performance, and even recitation when the text was been produced. We aim at observing the reading practices of the Roman society through poetic texts and at getting to know the reading protocols of that society at the moment when the maximum expansion of the written culture is achieved, i.e., the first and second centuries AD. 

Wine vessels (Vasa vinaria in roman law

Aličić Samir

2017-01-01

Full Text Available The notion of 'wine vessels' in Roman law comprises all the winecontaining recipients. There is no legal standardization of wine vessels by means of volume, and although the terms amphora, urna and culleus are used to designate both the vessels and the units of measure, these are two different meanings of the terms. In regard of the question, whether the vessels make appurtenance of the wine, jurisprudents of proculean school divided them in two categories. In the first category are those that follow legal status of wine, usually amphoras and other jars (cadi which are used for 'packaging', i. e. 'bottling' of the wine. The second category make mostly vats (cuppae and ceramic cisterns (dolia, which don't follow legal status of wine, making instead part of farming equipment of a landed property (instrumentum fundi and it's appurtenance. But, the roman jurists are not consistent regarding criteria for distinguishing these two categories.

Mosaic trisomy 8 detected by fibroblasts cultured of skin

Science.gov (United States)

Gómez, Ana M; Mora, Lina; Suarez-Obando, Fernando; Moreno, Olga

2016-01-01

Introduction: Mosaic trisomy 8 or "Warkany's Syndrome" is a chromosomopathy with an estimated prevalance of 1:25,000 to 1:50,000, whose clinical presentation has a wide phenotypic variability. Case Description: Patient aged 14 years old with antecedents of global retardation of development, moderate cognitive deficit and hypothyroidism of possible congenital origin. Clinical Findings: Physical examination revealed palpebral ptosis, small corneas and corectopia, hypoplasia of the upper maxilla and prognathism, dental crowding, high-arched palate, anomalies of the extremities such as digitalization of the thumbs, clinodactyly and bilateral shortening of the fifth finger, shortening of the right femur, columnar deviation and linear brown blotches that followed Blaschko's lines. Cerebral nuclear magnetic resonance revealed type 1 Chiari's malformation and ventriculomegaly. Although the karyotype was normal in peripheral blood (46,XY), based on the finding of cutaneous mosaicism the lesions were biopsied and cytogenetic analysis demonstrated mosaic trisomy 8: mos 47,XY,+8[7]/46,XY[93]. Clinical Relevance: Trisomy 8 is clinically presented as a mosaic, universal cases being unfailingly lethal. In this particular case, cutaneous lesions identified the mosaic in tissue, although the karyotype was normal in peripheral blood. The cutaneous mosaicism represented by brown linear blotches which follow Blaschko's lines is a clinical finding that has not previously been described in Warkany's syndrome. PMID:27546932

Roman Travertine is one of the most long-standing and famous stones, used since the times of the Roman Empire. Together with Carrara and Botticino marbles, it is probably the most worldwide well-known and diffused Italian dimension stone. Travertine derives its name from the former town, known as Tibur in ancient Roman times; the ancient name for the stone was Lapis Tiburtinus, meaning Tibur Stone, which was gradually corrupted to Travertino (travertine). The Roman Travertine is geographically located circa 25 km to the east of Rome, Central Italy, in the hilly area of Guidonia-Montecelio and Tivoli. Its deposit, formed during late Pleistocene time over an active strike-slip fault nearby the Colli Albani quiescent volcano, is about 20 km2 wide and 60 m thick on average; the thickness is over 85 m toward its western N-S-elongated side, where thermal springs and large sinkholes occur in an aligned pattern. The first quarries date back to pre-Roman times; nowadays three main productive sub-zones can be recognized within the extractive basin: "Valle Pilella", "Barco" and "Le Fosse", where more than fifty quarries are in operation, together with a relevant number of processing plants and artisanal laboratories. Lithological and stratigraphical features allow the distinction of an extensive number of commercial varieties, being the most renowned the Classic, the Bianco, the Noce, the Paglierino, the Navona. Used since more than 2.500 years, the Roman Travertine has deeply characterized the architecture of Rome and its history, with the realization of villas, palaces, artistic and monumental buildings, and masterpieces with unmistakable features, such as the Anfiteatro Flavio (the Colosseum), the Theatre of Marcellus, the St. Peter's Basilica and Colonnade, the Tritone Fountain, the Adriana Villa, the Trevi Fountain, and many others. From Renaissance times on, the travertine has been extensively used to build an innumerable amount of churches, common buildings and houses

An interdisciplinary study of the archaeological landscape of the Trieste area (northeastern Italy), mainly based on airborne light detection and ranging (LiDAR), ground penetrating radar (GPR), and archaeological surveys, has led to the discovery of an early Roman fortification system, composed of a big central camp (San Rocco) flanked by two minor forts. The most ancient archaeological findings, including a Greco-Italic amphora rim produced in Latium or Campania, provide a relative chronology for the first installation of the structures between the end of the third century B.C. and the first decades of the second century B.C. whereas other materials, such as Lamboglia 2 amphorae and a military footwear hobnail (type D of Alesia), indicate that they maintained a strategic role at least up to the mid first century B.C. According to archaeological data and literary sources, the sites were probably established in connection with the Roman conquest of the Istria peninsula in 178-177 B.C. They were in use, perhaps not continuously, at least until the foundation of Tergeste, the ancestor of Trieste, in the mid first century B.C. The San Rocco site, with its exceptional size and imposing fortifications, is the main known Roman evidence of the Trieste area during this phase and could correspond to the location of the first settlement of Tergeste preceding the colony foundation. This hypothesis would also be supported by literary sources that describe it as a phrourion (Strabo, V, 1, 9, C 215), a term used by ancient writers to designate the fortifications of the Roman army.

The smooth functioning of an ordered society depends on the possession of a means of regularising its activities over time. That means is a calendar, and its regularity is a function of how well it models the more or less regular movements of the celestial bodies - of the moon, the sun or the stars. Greek and Roman Calendars examines the ancient calendar as just such a time-piece, whose elements are readily described in astronomical and mathematical terms. The story of these calendars is one of a continuous struggle to maintain a correspondence with the regularity of the seasons and the sun, d

Sinkholes are a well-known geologic hazard but their past occurrence, useful for subsidence risk prediction, is difficult to define, especially for ancient historic times. Consequently, our knowledge about Holocene carbonate landscapes is often limited. A multidisciplinary study of Trieste Karst (Italy), close to early Roman military fortifications, led to the identification of possible ancient road tracks, cut by at least one sinkhole. Electrical Resistivity Tomography through the sinkhole has suggested the presence of a cave below its bottom, possibly responsible of the sinkhole formation, while Ground Penetrating Radar has detected no tectonic disturbances underneath the tracks. Additionally, archaeological surveys led to the discovery of over 200 Roman shoe hobnails within or close to the investigated route. According to these data, the tracks are interpreted as the remains of a main Roman road, whose itinerary has been reconstructed for more than 4 km together with other elements of ancient landscape. Our results provide the first known evidence of a Roman main road swallowed by sinkholes and suggest that Holocene karst landscapes could be much different from what previously believed. In fact, sinkholes visible nowadays in the investigated region could have been flat areas filled by sediments up to the Roman time.

The barbarians within. Illyrian colonists in roman Dacia

Irina NEMETI

2011-03-01

Full Text Available The present study attempts at grasping, as encompasing as possible, the process of acculturation undergone by peregrins from the Illyrian territories, a process that continued after their colonization in Dacia. The analysis follows the specific forms of organization of the various gentes arrived from Dalmatia (kastella, vicus, principes, noting the organized character of the colonization of these dalmatians, specialists in gold extraction. They were brought in compact groups and had their own institutions. The onomastic study took into consideration all persons who, through their names, relatives or origin, can be identified as illiri. Four groups of people have been identified, each illustrating a stage in their acculturation reflected in the onomastic system. In the field of religious life, one can note a continuous oscillation between the preservation of ancient values and the borrowing of new religious forms, which eventually lead to the colonized Illyrians assuming a new cultural identity. Learning Latin, acquiring Latin names, and adopting Roman gods indicates in historical terms their Romanization. In the funerary field, they were more conservative. As a funerary phenomenon, incineration with the deposition of calcined remains in ritually burnt pits is attributed to populations colonized in Dacia from the Dalmatian area. As for the inventory of their tombs and their funerary monuments on the other hand, one notes that they took over Roman material culture and used monuments that follow the canons of provincial art.

To investigate large structural clonal mosaicism of chromosome X, we analysed the SNP microarray intensity data of 38,303 women from cancer genome-wide association studies (20,878 cases and 17,425 controls) and detected 124 mosaic X events >2 Mb in 97 (0.25%) women. Here we show rates for X-chromosome mosaicism are four times higher than mean autosomal rates; X mosaic events more often include the entire chromosome and participants with X events more likely harbour autosomal mosaic events. X mosaicism frequency increases with age (0.11% in 50-year olds; 0.45% in 75-year olds), as reported for Y and autosomes. Methylation array analyses of 33 women with X mosaicism indicate events preferentially involve the inactive X chromosome. Our results provide further evidence that the sex chromosomes undergo mosaic events more frequently than autosomes, which could have implications for understanding the underlying mechanisms of mosaic events and their possible contribution to risk for chronic diseases.

Image mosaic has widely applications value in the fields of medical image analysis, and it is a technology that carries on the spatial matching to a series of image which are overlapped with each other, and finally builds a seamless and high quality image which has high resolution and big eyeshot. In this paper, the method of grayscale cutting pseudo-color enhancement was firstly used to complete the mapping transformation from gray to the pseudo-color, and to extract SIFT features from the images. And then by making use of a similar measure of NCC (normalized cross correlation - Normalized cross-correlation), the method of RANSAC (Random Sample Consensus) was used to exclude the pseudofeature points right in order to complete the exact match of feature points. Finally, seamless mosaic and color fusion were completed by using wavelet multi-decomposition. The experiment shows that the method we used can effectively improve the precision and automation of the medical image mosaic, and provide an effective technical approach for automatic medical image mosaic.

A quasi mosaic bent crystal for high-resolution diffraction of X and γ rays has been realized. A net curvature was imprinted to the crystal thanks to a series of superficial grooves to keep the curvature without external devices. The crystal highlights very high diffraction efficiency due to quasi mosaic curvature. Quasi mosaic crystals of this kind are proposed for the realization of a high-resolution focusing Laue lens for hard X-rays.

Mosaic boreal landscapes with open and forested wetlands

International Nuclear Information System (INIS)

Sjoeberg, K.; Ericson, L.

1997-01-01

We review patterns and processes important for biodiversity in the Fennoscandian boreal forest, describe man's past and present impact and outline a strategy for conservation. The boreal landscape was earlier characterized by a mosaic of open and forested wetlands and forests. Drainage and felling operation have largely changed that pattern. Several organisms depend upon the landscape mosaic. Natural ecotones between mire and forest provide food resources predictable in space and time contrasting to unpredictable edges in the silvicultured landscape. The mosaic is also a prerequisite for organisms dependent on non-substitutable resources in the landscape. The importance of swamp forests has increased as they function as refugia for earlier more widespread old-growth species. Programmes for maintaining biodiversity in the boreal landscape should include the following points. First, the natural mosaic with open and forested wetlands must be maintained. Second, swamp forests must receive a general protection as they often constitute the only old-growth patches in the landscape. Third, we need to restore earlier disturbance regimes. Present strategy plans for conservation are insufficient, as they imply that a too large proportion of boreal organisms will not be able to survive outside protected areas. Instead, we need to focus more on how to preserve organisms in the man-influenced landscape. As a first step we need to understand how organisms are distributed in landscapes at various spatial scales. We need studies in landscapes where the original mosaic has faced various degrees of fragmentation. (au) 124 refs

Roman capitals from Sirmium (Sremska Mitrovica, Serbia

2009-01-01

Full Text Available The article brings a detailed formal analysis of the Roman capitals from Sirmium, in the light of the stone analysis conducted on the material at the Museum of Srem and elsewhere in Sremska Mitrovica. The capitals dot the historical development of the town from the first half of the 2nd century until the 4th century. First made of regional limestone, they were later joined by those of limestone and marbles of distant source, whereby different stones in capitals coexisted almost throughout the town’s development. This was certainly the situation during the flourishing times of the late 3rd and the 4th century, when Sirmium, as one of the four capitals of the Roman Empire, stood within several formal circles of capitals. The plain-leaved capitals tie it to the rest of Pannonia, the Corinthianizing capitals to the provinces to the east and south, while part of the Asiatic capitals, the largest group, tie it to the wider area of the Mediterranean.

Tissue differences in fragile X mosaics: Mosaicism in blood cells may differ greatly from skin

The fragile X mutation is diagnosed from the structure of the FMR1 gene in blood cell DNA. An estimated 12 to 41% of affected males are mosaics who carry both a {open_quotes}full mutation{close_quotes} allele from which there is no gene expression and a {open_quotes}premutation{close_quotes} allele which has normal gene expression. We compared the DNA in blood cells and skin fibroblasts from four mosaic fragile X males to see if there was a difference in the relative amounts of premutation and full mutation alleles within the tissues of these individuals. Two of these males showed striking differences in the ratio of premutation to full mutation in different tissues while the other two showed only slight differences. These observations conform with the widely accepted hypothesis that the fragile X CGG repeat is unstable in somatic tissue during early embryogenesis. Accordingly, the mosaicism in brain and skin, which are both ectodermal in origin, may be similar to each other but different from blood which is not ectodermal in origin. Thus, the ratio of full mutation to premutation allele in skin fibroblasts might be a better indicator of psychological impairment than the ratio in blood cells. 24 refs., 4 figs., 1 tab.

Location of quarries of magnesian lime used as raw material of Roman plasters in western Lombardy (Italy

Full Text Available Lime as building material was widely diffused in Roman architecture of western Lombardy. The presence of magnesite (magnesium carbonate was detected in painted plasters coming from roman sites of Milano: magnesite indicates the use of dolomite to make the lime. Dolomite rocks widely outcrop in the Lombard Prealps: light grey dolomites and dolomitic limestones (Dolomia del Salvatore, Ladinian-Anisian; grey dolomites, sometimes with cyclothemes (Dolomia Principale, Norian. There is no evidence of Roman lime quarries or kilns in this area; the Romans probably exploited the same dolomite outcrops, located along the eastern shore of lake Maggiore, where lime was produced from the Middle Ages onwards. The glacio-fluvial deposits of the middle course of the river Adda (cobbles, pebbles of siliceous limestone together with limestone and dolomite outcropping in the river basin were another medieval and modern source of raw material, mainly to make a moderately hydraulic lime (called “calce forte”, but this kind of lime is lacking in Roman plasters.

Incentive loss and hippocampal gene expression in inbred Roman high- (RHA-I) and Roman low- (RLA-I) avoidance rats.

2013-11-15

Two recent microarray and qRT-PCR studies showed that inbred Roman high- (RHA-I, low anxiety and frustration vulnerability) and low-avoidance (RLA-I, high anxiety and frustration vulnerability) rats, psychogenetically selected on the basis of their divergence in two-way avoidance performance, differed in basal whole-brain and hippocampal expression of genes related to neurotransmission, emotion, stress, aversive learning, and drug seeking behavior. We have extended these studies by analyzing strain differences in hippocampal gene expression following a frustrative experience involving reward downshift, i.e. instrumental successive negative contrast (iSNC), a phenomenon in which the sudden reduction of an expected reward induces frustration/anxiety. Food-deprived male Roman rats were exposed to a reduction in the amount of solid food presented in the goal of a straight alley (from 12 pellets in "training" trials - i.e. preshift trials- to 2 pellets in "frustration testing" trials - i.e. postshift trials-). The iSNC effect, as measured by response latencies in the "postshift" trials, appeared only in RLA-I rats (i.e. higher response latencies in the 12-2 RLA-I group as compared to the 2-2 RLA-I control group in postshift trials). Two and a half hours after the "postshift" behavioral test, hippocampi were removed and stored (-80°C) until analysis. Microarray analysis of these hippocampi showed that four differentially-expressed, and qRT-PCR-validated genes (TAAR2, THAP1, PKD2L1, NANOS), have relevance for brain function and behavior, including schizophrenia, depression, anxiety, and drug addiction, thus showing the usefulness of Roman strains as a genetic model for research on the neurogenetic basis of frustration.

Locating the timacum maius station on the roman road lissus-naissus-ratiaria: New archaeological research

Directory of Open Access Journals (Sweden)

Petrović Vladimir P.

2008-01-01

Full Text Available As the exact location of two Timacum stations remains an open issue, the results of the latest archaeological investigations in the environs of Svrljig, southeast Serbia, seem to offer some corroborative evidence for the hypothesis proposed in our previous contribution that this might be the location of Roman Timacum Maius. A small-scale trial excavation was undertaken on the Roman site at Kalnica in the Niševac village area in July 2008. A trench 4 by 2m was opened in the zone of the site that had yielded plentiful fragments of building debris as well as small finds. A massive wall over 1m thick was found immediately beneath the surface. Built of bro­ken limestone and pebbles bound with lime mortar, it obviously was part of a larger structure. To the northeast of the wall was an area covered with fragmented roof tiles. The discovery of two ceramic tumuli embedded in the wall, indicating a wall-heating system so far unregistered on the representative Roman urban and settlement sites in Serbia, gives additional grounds to presume that this was a larger Roman settlement extending over an area of more than 5ha, possibly Timacum Maius, a station on the Roman road Lissus-Ratiaria-Naissus.

The plague under Marcus Aurelius and the decline and fall of the Roman Empire.

Science.gov (United States)

Fears, J Rufus

2004-03-01

The Roman Empire of the second century was a superpower that, in relative terms, dominated its world as much as the United States does today. In 166 AD, a plague broke out od pandemic proportions. The pandemic ravaged the entire extent of the Roman Empire, from its eastern frontiers in Iraq to its western frontiers on the Rhine River and Gaul, modern France, and western Germany. The disease is identified most often as smallpox, but it may have been anthrax. The study of bacterial DNA may enable identification of this plague that ravaged the Roman Empire at recurrent intervals for more than 100 years and that had a significant role in the decline and fall of this great superpower.

Salquisa and Alttoglass have developed a very innovative product : the retro reflective glass mosaic. This new product can be used in both horizontal and vertical signposting and also in interior design and architecture. This particular product has many advantages compare to the traditional methods used for signposting, design or architecture. One of them is that the product is mainly made of glass therefore it can last much longer than paints for example. The used of glass mosaic for civil engineering it is opened up especially for signposting and it contributes to improve visibility at night not only in standard conditions but also in the hard ones such as wind, fog or rain at nighttimes. Higher visibility = higher security. We should remember that a high percentage of accidents occur under rain conditions at night. The glass mosaic is presented in a mesh which allows the use in both plane and curve surfaces in signposting, interior design and architecture. The retro reflective effect last under the water therefore the mosaic can be fixed in ornamental and decorative fountains, swimming pools, etc. Furthermore, the retro reflective effect can also be applied on big size ceramic tiles. This project was developed along with the Institute of Ceramic Technology (ITC), it was supported by the Center for Industrial Technological Development (CDTI) and it is also patented. (Author)

Mas Gusó: a Roman military Settlement in the suburbium of Emporiae

2016-11-01

Full Text Available Although the site of Mas Gusó (province of Girona has been interpreted as a Roman uilla, this is actually a public building. Its existence have to be contextualized within the frame of the structures established by the Roman authority for territorial control closely linked to the creation of a new road network and a tax collection system. We also analyse its survival until the 3rd century AD, which are closely related to the nearby city of Emporiae.

Sewerage system (cloaca), which implies any cavity through which waste water flows, has in Roman law a special legal protection due to its importance for public health preservation and safety of citizens. In Praetorian Edict, two interdicts are envisaged; one prohibitory, by which private sewerage system is protected and one restitutory, by which public sewerage system is protected. It is possible that a restitutory interdict about private sewerage system existed. By the public sewerage inter...

Bekker-Nielsen, Tønnes

2016-01-01

The reorganisation of Pontos that Pompey carried out after defeating Mithradates VI Eupator has traditionally been seen as an example of enlightened Roman policy towards the provincials, which included the introduction of civic self-government and the promotion of commercial life. These goals...... Pompey attempted to achieve by establishing five urban communities along an existing east-west artery known as the “Pontic road”. A closer examination of the textual evidence and the actual remains of the “Pontic road”, however, indicate that the road had not been a trade route of any significance before...... the Roman conquest and that the motives behind Pompey’s dispositions were of a strategic, rather than a commercial, nature....

Analysis of Roman glass from Albania by PIXE–PIGE method

International Nuclear Information System (INIS)

Šmit, Ž.; Tartari, F.; Stamati, F.; Vevecka Priftaj, A.; Istenič, J.

2013-01-01

A series of 31 Roman glasses dated to the 1st–4th c. AD from the present Albania was analyzed by the combined PIXE–PIGE method. The analysis shows typical natron-based glass of the Roman period, though statistical treatment using principal component analysis and bivariate plots reveals four distinct groups, which are qualified by increased levels of potassium, magnesium and titanium–manganese–iron oxides, respectively. MgO content may exceed 2% and reach the level commonly accepted for halophytic plant-ash glass. The groups are formed on account of mineral impurities in the sand, which gives support to the thesis of multiple production centers of raw glass in the imperial age

Roman primacy and the development of the synodal institution in the period of the Arian controversy

Zakharov Georgii

2015-01-01

Full Text Available The object of this study is process of evolution of church organization in the 4th century, especially the relationships between Roman primacy and synodal institution in the epoch of the Arian controversy. The author examines evolution of the institution of the Roman synod and practice of participation of the Roman See in church councils outside Rome, focusing on the unsuccessful attempt to convene the general council in Rome in 382. Analysis of historical data shows that the ability of the Roman see to organize in a short time a representative council (mainly of the Italian bishops allowed Rome to claim for a special status within the church communion. In the same time the Roman See did not become in the 4th century the center of conciliar activity at the universal level. Participation of Rome in Ecumenical and Western councils was quite passive. In the second part of the paper the author attempts to reconstruct various models of church organization, which were typical for the western and the eastern episcopate in the 4th century. The author concludes that the real initiator of the development of universal primacy of Rome was not originally the pope, but the western episcopate (council of Serdica, 343. In the second part of the 4th century pope Damasus developed this conception, putting the principle of primacy of the Roman See as the chair of Peter above principle of synodal consensus. At the same time eastern bishops considered the Roman chair as the center of the West, rather than the head of the whole Church. Sometimes they invited bishop of Rome and other western bishops to act as arbiters in the eastern conflicts, but more often they defended the idea of full autonomy of the East.

Reassessing Jacob Strauss and the Mosaic Code

2012-01-01

Full Text Available This article reviewed claims made by modern scholars Ford Lewis Battles, G.H. Williams, and Theodore Tappert concerning the views of Jacob Strauss (1480–1530, court preacher at Eisenach, particularly in regard to the imposition of Mosaic Law upon the civil realm. Most pointedly, Battles claims Strauss proposed to replace European civil law completely with the ‘entire Mosaic code’. This study examined Strauss’s relevant writings to determine his position on Mosaic Law and civil law and demonstrated that the claims of Battles, Williams, and Tappert were not supported by the primary source evidence. Selections from Strauss’ 51 theses on usury are translated into English for the first time. To a much lesser degree, this study addressed the issue in regard to the Weimar court preacher Wolfgang Stein, against whom the same claims were made. A paucity of evidence rendered those claims dubious in his case. In the end we were left only with unsubstantiated second-hand claims against these men.

A MULTI-CORE PARALLEL MOSAIC ALORITHM FOR MULTI-VIEW UAV IMAGES

Directory of Open Access Journals (Sweden)

X. Pan

2017-09-01

Full Text Available As the spread of the error and accumulation often lead to distortion or failure of image mosaic during the multi-view UAV (Unmanned Aerial Vehicle images stitching. In this paper, to solve the problem we propose a mosaic strategy to construct a mosaic ring and multi-level grouping parallel acceleration as an auxiliary. First, the input images will be divided into several groups, each group in the ring way to stitch. Then, use SIFT for matching, RANSAC to remove the wrong matching points. And then, calculate the perspective transformation matrix. Finally weaken the error by using the adjustment equation. All these steps run between different groups at the same time. By using real UAV images, the experiment results show that this method can effectively reduce the influence of accumulative error, improve the precision of mosaic and reduce the mosaic time by 60 %. The proposed method can be used as one of the effective ways to minimize the accumulative error.

Roman Ways: The Endurance of Patterns in Travel and Hospitality from Antiquit

Full Text Available Although it seems clear that multi-unit hotel and restaurant brands proliferated in the United States during the twentieth century, historical research demonstrates that the phenomenon is actually much older. The origins of hospitality chains can be traced back to the Roman Empire. Organizational systems and travel behaviors have remained remarkably similar throughout Western civilization during the past two millennia. The Roman relay station, the medieval post house, the New England inn, the railroad restaurant, and the highway hotel all share a common heritage.

Remo cum fratre Quirinus: Metamorphoses of the Roman Foundation Myth from its Beginnings to Horace

Directory of Open Access Journals (Sweden)

Špela Tomažinčič

2008-07-01

Full Text Available From the first reference to Romulus by Alcimus, a historian from the mid-fourth century BC, where the hero appears alone, down to the age of Augustus, the story of the foundation of Rome underwent considerable plot changes. The two most important are, firstly, Romulus' later role not merely as a conditor urbis, but – in keeping with the Hellenistic tradition of ktiseis poleon – mainly as a creator gentis and a model of the new Roman, who can subsequently embody a new ethnic identity; and, secondly, the later dichotomy of the founders. The interpretation of the Roman foundation myth must be therefore closely associated with the symbolism of numbers – one founder as opposed to twin founders – as it is reflected in different socio-political and historical contexts. In addition to shaping society, myth also documents all its changes. In the context of replacing a single founder with twin founders, Romulus and Remus, the first critical change is the introduction of Remus. The twin founders imply a double community, a notion which becomes meaningful in Rome only after the plebeian achievement of political equality between 367 and 342 BC. The second significant change is the death of Remus, involving the notion of a foundation sacrifice, for which the evidence points to the crisis of 296 BC. The foundation story also serves as an explanation model for the events in the Late Roman Republic. Horace's pessimistic Seventh Epode evokes the foundation crime of fratricide to explain the tragic pattern of civil wars. As Romulus' successors, the Romans are also heirs to his crime, to the scelus fraternae necis, from which they cannot escape. Moreover, Romulus as a creator gentis represents a potential source for the Roman change of identity, which was regarded as coincidental with the foundation act. This recurring theme is elaborated first in Ennius' Annals and later in Vergil's Aeneid and Horace's Third ‘Roman Ode’. The central motif is Ennius�

Mosaic Pattern of Lung Attenuation on Chest CT in Patients with Pulmonary Hypertension

Full Text Available A mosaic pattern of lung attenuation on chest computed tomography (CT may be due to various etiologies. There is limited published data on CT results when used to evaluate pulmonary hypertension (PH. We retrospectively studied the frequency of mosaic pattern in patients with PH and the cause of the PH by diagnostic group, as well as the correlation between the mosaic pattern and the following: demographics, severity of the PH, main pulmonary artery (PA size, PA/aorta (PA/Ao ratio, pulmonary function tests (PFT, and ventilation perfusion scan results. Overall, 18% of the cohort had CT mosaic pattern (34/189. Mosaic pattern was present in 17/113 (15% in Group 1 pulmonary arterial hypertension, 5/13 (28% in Group 2 pulmonary venous hypertension and 8/50 (16% in Group 3 PH. Conversely, Group 4 chronic thromboembolic PH was more prevalent in 4/8 (50%. Main PA size, PA/Ao ratio, and segmental perfusion defect were positively associated with mosaic pattern. In contrast, factors such as age, gender, body mass index, functional class, hemodynamic data, and PFT values were not associated with mosaic pattern. Mosaic pattern is not specific as an isolated finding for distinguishing the subtype of PH.

AUTOMATIC AND GENERIC MOSAICING OF MULTISENSOR IMAGES: AN APPLICATION TO PLEIADES HR

Directory of Open Access Journals (Sweden)

F. Bignalet-Cazalet

2012-07-01

Full Text Available In the early phase of the Pleiades program, the CNES (the French Space Agency specified and developed a fully automatic mosaicing processing unit, in order to generate satellite image mosaics under operational conditions. This tool can automatically put each input image in a common geometry, homogenize the radiometry, and generate orthomosaics using stitching lines. As the image quality commissioning phase of Pleiades1A is on-going, this mosaicing process is being tested for the first time under operational conditions. The French newly launched high resolution satellite can acquire adjacent images for French Civil and Defense User Ground Segments. This paper presents the very firsts results of mosaicing Pleiades1A images. Beyond Pleiades’ use, our mosaicing tool can process a significant variety of images, including other satellites and airborne acquisitions, using automatically-taken or external ground control points, offering time-based image superposition, and more. This paper also presents the design of the mosaicing tool and describes the processing workflow and the additional capabilities and applications.

New radiocarbon data to study the history of roman and medieval Florence

Florence is a town worldwide known for its Renaissance masterpieces. It is often forgotten that it was founded during Roman times and remained a small village until the end of the early Middle Ages, practically confined within the ancient Roman boundaries. Since 2003, an extended archaeological research executed by the University of Sienna has studied the most ancient layers in the centre of Florence with the aim to enhance both the archaeological and paleo-environmental reconstruction of this area. One of the peculiarities of these excavations is that the early medieval layers were poor in datable ceramics, thus charcoals were sampled from different stratigraphic layers in order to contribute to the dating. Several data have already been published; here we focus on the excavation site of Palazzo Vecchio, now the seat of the municipality of Florence. This area is located close to the Arno river, along the eastern margin of the slightly elevated height upon which the Roman town was founded; actually, in the layers beneath the surface, the Roman theatre is still preserved. Radiocarbon dating of charcoals was performed in the LABEC laboratory in Florence, at the AMS beam line of the AMS-IBA 3 MV Tandetron accelerator. Comparison of these new data with the former ones and with the archaeological and geological data adds new information especially on natural phenomena like floods and on the human occupation of this area in the past.

Relating 2-Rainbow Domination To Roman Domination

Full Text Available For a graph G, let R(G and yr2(G denote the Roman domination number of G and the 2-rainbow domination number of G, respectively. It is known that yr2(G ≤ R(G ≤ 3/2yr2(G. Fujita and Furuya [Difference between 2-rainbow domination and Roman domination in graphs, Discrete Appl. Math. 161 (2013 806-812] present some kind of characterization of the graphs G for which R(G − yr2(G = k for some integer k. Unfortunately, their result does not lead to an algorithm that allows to recognize these graphs efficiently. We show that for every fixed non-negative integer k, the recognition of the connected K4-free graphs G with yR(G − yr2(G = k is NP-hard, which implies that there is most likely no good characterization of these graphs. We characterize the graphs G such that yr2(H = yR(H for every induced subgraph H of G, and collect several properties of the graphs G with R(G = 3/2yr2(G.

Apple Latent Spherical Virus Vector as Vaccine for the Prevention and Treatment of Mosaic Diseases in Pea, Broad Bean, and Eustoma Plants by Bean Yellow Mosaic Virus

Full Text Available We investigated the protective effects of a viral vector based on an Apple latent spherical virus (ALSV harboring a segment of the Bean yellow mosaic virus (BYMV genome against mosaic diseases in pea, broad bean, and eustoma plants caused by BYMV infection. In pea plants pre-inoculated with the ALSV vaccine and challenge inoculated with BYMV expressing green fluorescence protein, BYMV multiplication occurred in inoculated leaves, but was markedly inhibited in the upper leaves. No mosaic symptoms due to BYMV infection were observed in the challenged plants pre-inoculated with the ALSV vaccine. Simultaneous inoculation with the ALSV vaccine and BYMV also prevented mosaic symptoms in broad bean and eustoma plants, and BYMV accumulation was strongly inhibited in the upper leaves of plants treated with the ALSV vaccine. Pea and eustoma plants were pre-inoculated with BYMV followed by inoculation with the ALSV vaccine to investigate the curative effects of the ALSV vaccine. In both plant species, recovery from mosaic symptoms was observed in upper leaves and BYMV accumulation was inhibited in leaves developing post-ALSV vaccination. These results show that ALSV vaccination not only prevents mosaic diseases in pea, broad bean, and eustoma, but that it is also effective in curing these diseases.

Roman concept of mental capacity to make end-of-life decisions.

Science.gov (United States)

Mendelson, Danuta

2007-01-01

When assessing decisional competence of patients, psychiatrists have to balance the patients' right to personal autonomy, their condition and wishes against principles of medical ethics and professional discretion. This article explores the age-old legal and ethical dilemmas posed by refusal of vital medical treatment by patients and their mental capacity to make end-of-life decisions against the background of philosophical, legal and medical approaches to these issues in the time of the Younger Pliny (c62-c113 CE). Classical Roman discourse regarding mental competency and "voluntary death" formed an important theme of the vast corpus of Greco-Roman writings, which was moulded not only by legal permissibility of suicide but also by philosophical (in modern terms, moral or ethical) considerations. Indeed, the legal and ethical issues of evaluating the acceptability of end of life decisions discussed in the Letters are as pertinent today as they were 2000 years ago. We may gain valuable insights about our own methodologies and frames of reference in this area of the law and psychiatry by examining Classical Roman approaches to evaluating acceptability of death-choices as described in Pliny's Letters and the writings of some of his peers.

In the frame of an ongoing archeological study on the Sabina area, a countryside close to Rome, white and red samples of roman wall paintings have been investigated by combining X-ray diffraction and different spectroscopic methodologies, namely laser induced breakdown spectroscopy, μ-Raman and Fourier transform infrared attenuated total reflectance spectroscopy. The used multi-technique approach has allowed the unambiguous identification of the red pigment as red ochre and has provided insight on the provenance of both the pigment and the material used for the realization of the wall paintings. The experimental results have confirmed some assumptions on the use of local materials in roman rural architecture.

Analyses of genome-wide association study (GWAS) data have revealed that detectable genetic mosaicism involving large (>2 Mb) structural autosomal alterations occurs in a fraction of individuals. We present results for a set of 24,849 genotyped individuals (total GWAS set II [TGSII]) in whom 341 large autosomal abnormalities were observed in 168 (0.68%) individuals. Merging data from the new TGSII set with data from two prior reports (the Gene-Environment Association Studies and the total GWAS set I) generated a large dataset of 127,179 individuals; we then conducted a meta-analysis to investigate the patterns of detectable autosomal mosaicism (n = 1,315 events in 925 [0.73%] individuals). Restricting to events >2 Mb in size, we observed an increase in event frequency as event size decreased. The combined results underscore that the rate of detectable mosaicism increases with age (p value = 5.5 × 10−31) and is higher in men (p value = 0.002) but lower in participants of African ancestry (p value = 0.003). In a subset of 47 individuals from whom serial samples were collected up to 6 years apart, complex changes were noted over time and showed an overall increase in the proportion of mosaic cells as age increased. Our large combined sample allowed for a unique ability to characterize detectable genetic mosaicism involving large structural events and strengthens the emerging evidence of non-random erosion of the genome in the aging population.

Analyses of microsamples collected from Roman catacombs and samples of lime-pozzolana mortars hardened in the laboratory display higher contents in carbonated binder than other subaerial Roman monuments. The measured environmental data inside the Saint Callistus and Domitilla catacombs show a constant temperature of 15-17 deg C, a high CO 2 content (1700 to 3500 ppm) and a relative humidity close to 100%. These conditions and particularly the high CO 2 concentration speed-up the lime calcitization roughly by 500% and reduce the cationic diffusion to form hydrous calcium aluminosilicates. The structure of Roman catacomb mortars shows (i) coarser aggregates and thicker beds on the inside, (ii) thin, smoothed, light and fine-grained external surfaces with low content of aggregates and (iii) paintings and frescoes on the outside. The observed high porosity of the mortars can be attributed to cracking after drying linked with the high binder content. Hardened lime lumps inside the binder denote low water/mortar ratios for slaking. The aggregate tephra pyroclasts rich in aluminosilicate phases with accessorial amounts of Ba, Sr, Rb, Cu and Pb were analysed through X-ray diffraction (XRD), electron microprobe analysis (EMPA) and also by environmental scanning electron microscopy (ESEM) to identify the size and distribution of porosity. Results support procedures using local materials, special mortars and classic techniques for restoration purposes in hypogeal backgrounds

The historiography of the Later Roman Empire: from maximal state to minimal state, and back again

Directory of Open Access Journals (Sweden)

Uiran Gebara da Silva

2017-11-01

Full Text Available The paper analyses the conceptual models of state used by the scholarship of the later Roman Empire. The argument here developed is that it is possible to identify an oscillation between opposing conceptions of state, sometimes maximalist, sometimes minimalist, and that such conceptions have almost always served as an explanatory structure of the later Roman Empire historical developments, with the greater or smaller size of that State seen alternately as the cause for either the disarticulation or maintenance of the Roman system in the Mediterranean. The paper presents an historical review of those conceptions, elaborates on their connections with the debate between modernism and primitivism in the ancient economy and deals with their structuring ideological assumptions and the almost ubiquitous presence of liberal ideological categories and assumptions (even among Marxist authors. The paper concludes by reflecting on how this historiographical opposition between minimalist and maximalist conceptions obscures our understanding of the class relations of the later Roman imperial system of government.

Zaim, Mohammad; Kumar, Yogesh; Hallan, Vipin; Zaidi, A A

Velvet bean [Mucuna pruriens (L.) DC] is one of the most important medicinal plants. It is used to treat many ailments, but is widely used for the treatment especially for Parkinson's disease because of the presence of 3,4-dihydroxyphenylalanine (L-dopa) in it. It was noticed in last 5 years that the plants in the field showed severe mosaic, downward curling of the leaves, stunting, etc. This is consistently observed over the years in India. The disease was transmitted by whiteflies and by grafting and the causal agent was found to be a bipartite begomovirus. The whole genome was amplified by rolling circle amplification (RCA) using ϕ-29 DNA polymerase and characterized. DNA-A and DNA-B shared a 124-nucleotide (nt) long highly conserved (98%) common region (CR). Comparisons with other begomovirus showed that DNA-A sequence has highest identity (76%) with an isolate of Mungbean yellow mosaic India virus (MYMIV; AY937195) reported from India. This data suggested that the present isolate is a new species of genus Begomovirus for which the name "Velvet bean severe mosaic virus" (VbSMV) is proposed. DNA-B has a maximum sequence identity of 49% with an isolate of Horsegram yellow mosaic virus (HgYMV; AM932426) reported from India. Infectious clones consisting of a 1.7 mer partial tandem repeat of DNA-A and a dimer of DNB-B were constructed and agro-inoculated to Macuna pruriens (L.) DC plants, which showed field observed symptoms 24 days post-infiltration (dpi). In phylogenetic analysis, DNA-A and DNA-B of the present isolate grouped with DNA-A of different begomoviruses reported from fabaceous crops. The study presents first ever molecular evidence of any disease in velvet bean and whole genome analysis of the causative virus which is a distinct bipartite species of Begomovirus.

Performance Evaluations for Super-Resolution Mosaicing on UAS Surveillance Videos

Directory of Open Access Journals (Sweden)

Aldo Camargo

2013-05-01

Full Text Available Abstract Unmanned Aircraft Systems (UAS have been widely applied for reconnaissance and surveillance by exploiting information collected from the digital imaging payload. The super-resolution (SR mosaicing of low-resolution (LR UAS surveillance video frames has become a critical requirement for UAS video processing and is important for further effective image understanding. In this paper we develop a novel super-resolution framework, which does not require the construction of sparse matrices. The proposed method implements image operations in the spatial domain and applies an iterated back-projection to construct super-resolution mosaics from the overlapping UAS surveillance video frames. The Steepest Descent method, the Conjugate Gradient method and the Levenberg-Marquardt algorithm are used to numerically solve the nonlinear optimization problem for estimating a super-resolution mosaic. A quantitative performance comparison in terms of computation time and visual quality of the super-resolution mosaics through the three numerical techniques is presented.

Counselling considerations for chromosomal mosaicism detected by preimplantation genetic screening.

Besser, Andria G; Mounts, Emily L

2017-04-01

The evolution of preimplantation genetic screening (PGS) for aneuploidy to blastocyst biopsy and more sensitive 24-chromosome screening techniques has resulted in a new diagnostic category of PGS results: those classified as mosaic. This diagnosis presents significant challenges for clinicians in developing policies regarding transfer and storage of such embryos, as well as in providing genetic counselling for patients prior to and following PGS. Given the high frequency of mosaic PGS results and the wide range of possible associated outcomes, there is an urgent need to understand how to appropriately counsel patients regarding such embryos. This is the first commentary to thoroughly address pre- and post-test genetic counselling recommendations, as well as considerations regarding prenatal screening and diagnosis. Current data on mosaic PGS results are summarized along with embryo selection considerations and potential outcomes of embryos diagnosed as mosaic. Copyright © 2017 Reproductive Healthcare Ltd.

FOXG1-related disorders are caused by heterozygous mutations in FOXG1 and result in a spectrum of neurodevelopmental phenotypes including postnatal microcephaly, intellectual disability with absent speech, epilepsy, chorea, and corpus callosum abnormalities. The recurrence risk for de novo mutations in FOXG1-related disorders is assumed to be low. Here, we describe three unrelated sets of full siblings with mutations in FOXG1 (c.515_577del63, c.460dupG, and c.572T > G), representing familial recurrence of the disorder. In one family, we have documented maternal somatic mosaicism for the FOXG1 mutation, and all of the families presumably represent parental gonadal (or germline) mosaicism. To our knowledge, mosaicism has not been previously reported in FOXG1-related disorders. Therefore, this report provides evidence that germline mosaicism for FOXG1 mutations is a likely explanation for familial recurrence and should be considered during recurrence risk counseling for families of children with FOXG1-related disorders. © 2015 Wiley Periodicals, Inc.

A fast and automatic mosaic method for high-resolution satellite images

Science.gov (United States)

Chen, Hongshun; He, Hui; Xiao, Hongyu; Huang, Jing

2015-12-01

We proposed a fast and fully automatic mosaic method for high-resolution satellite images. First, the overlapped rectangle is computed according to geographical locations of the reference and mosaic images and feature points on both the reference and mosaic images are extracted by a scale-invariant feature transform (SIFT) algorithm only from the overlapped region. Then, the RANSAC method is used to match feature points of both images. Finally, the two images are fused into a seamlessly panoramic image by the simple linear weighted fusion method or other method. The proposed method is implemented in C++ language based on OpenCV and GDAL, and tested by Worldview-2 multispectral images with a spatial resolution of 2 meters. Results show that the proposed method can detect feature points efficiently and mosaic images automatically.

2005-04-01

Mosaic autosomal duplications are rare and often result in mental retardation and congenital anomalies. Phenotype is not predictable depending on the chromosomal imbalance involved and the percentage and tissues distribution of unbalanced cells. We report on a young woman carrying a mosaic duplication of chromosome 4p, evaluated because of three abortions due to IUGR and fetal malformation. Mosaic dup(4p) was detected by standard and molecular cytogenetics. Unbalanced cells accounted for about 20 to 30% of nuclei in four examined tissues and did not cause any obvious phenotypic effect. It is likely that mosaic duplications are underascertained because they are not associated with obvious clinical effects in some individuals. Prenatal diagnosis is the method of choice to predict the karyotype in the offspring of subjects carrying mosaic chromosome imbalances.

2011-08-15

An archaeometallurgical analysis of samples of lead sheathing from five ships of the Roman period was carried out in order to determine their composition and microstructure, and to obtain a better understanding of their manufacturing processes. The examinations included optical microscopy of metallographic cross-sections, microhardness tests, scanning electron microscopy, including energy dispersive spectroscopy, and X-ray photoelectron spectroscopy. The results show that the samples were all composed of lead covered with an oxide layer. The sheet thicknesses, microhardness values and microhardness distribution, as well as the grain size distribution, led to the conclusion that all of the sheets were produced by the same technology, using hammering, and were probably used for the same purpose. The presence of antimony was observed in the sample from the Roman ship from Caesarea, which may hint at an Italian (Sardinian) origin of the material, and perhaps of the ship. - Research Highlights: {yields} During the Roman period ship hulls were sheathed with lead. {yields} Five samples have been analysed for their characteristics and manufacturing process. {yields} The process was cold-working (strain-hardening) using hammering. {yields} The lead was open-casted on a flat stone, and later hammered at room temperature. {yields} Antimony in the Caesarea shipwreck may indicate an Italian origin of construction.

To explore the anatomic correlation of the retinal cone mosaic on adaptive optics images. Retrospective nonconsecutive observational case series. A retrospective review of the multimodal imaging charts of 6 patients with focal alteration of the cone mosaic on adaptive optics was performed. Retinal diseases included acute posterior multifocal placoid pigment epitheliopathy (n = 1), hydroxychloroquine retinopathy (n = 1), and macular telangiectasia type 2 (n = 4). High-resolution retinal images were obtained using a flood-illumination adaptive optics camera. Images were recorded using standard imaging modalities: color and red-free fundus camera photography; infrared reflectance scanning laser ophthalmoscopy, fluorescein angiography, indocyanine green angiography, and spectral-domain optical coherence tomography (OCT) images. On OCT, in the marginal zone of the lesions, a disappearance of the interdigitation zone was observed, while the ellipsoid zone was preserved. Image recording demonstrated that such attenuation of the interdigitation zone co-localized with the disappearance of the cone mosaic on adaptive optics images. In 1 case, the restoration of the interdigitation zone paralleled that of the cone mosaic after a 2-month follow-up. Our results suggest that the interdigitation zone could contribute substantially to the reflectance of the cone photoreceptor mosaic. The absence of cones on adaptive optics images does not necessarily mean photoreceptor cell death. Copyright © 2015 Elsevier Inc. All rights reserved.

Germline variants in the APC gene cause familial adenomatous polyposis. Inherited variants in MutYH, POLE, POLD1, NTHL1, and MSH3 genes and somatic APC mosaicism have been reported as alternative causes of polyposis. However, ~30-50% of cases of polyposis remain genetically unsolved. Thus, the aim of this study was to investigate the genetic causes of unexplained adenomatous polyposis. Eight sporadic cases with >20 adenomatous polyps by 35 years of age or >50 adenomatous polyps by 55 years of age, and no causative germline variants in APC and/or MutYH, were enrolled from a cohort of 56 subjects with adenomatous colorectal polyposis. APC gene mosaicism was investigated on DNA from colonic adenomas by Sanger sequencing or Whole Exome Sequencing (WES). Mosaicism extension to other tissues (peripheral blood, saliva, hair follicles) was evaluated using Sanger sequencing and/or digital PCR. APC second hit was investigated in adenomas from mosaic patients. WES was performed on DNA from peripheral blood to identify additional polyposis candidate variants. We identified APC mosaicism in 50% of patients. In three cases mosaicism was restricted to the colon, while in one it also extended to the duodenum and saliva. One patient without APC mosaicism, carrying an APC in-frame deletion of uncertain significance, was found to harbor rare germline variants in OGG1, POLQ, and EXO1 genes. In conclusion, our restrictive selection criteria improved the detection of mosaic APC patients. In addition, we showed for the first time that an oligogenic inheritance of rare variants might have a cooperative role in sporadic colorectal polyposis onset.

Mosaic serine proteases in the mammalian central nervous system.

Mitsui, Shinichi; Watanabe, Yoshihisa; Yamaguchi, Tatsuyuki; Yamaguchi, Nozomi

2008-01-01

We review the structure and function of three kinds of mosaic serine proteases expressed in the mammalian central nervous system (CNS). Mosaic serine proteases have several domains in the proenzyme fragment, which modulate proteolytic function, and a protease domain at the C-terminus. Spinesin/TMPRSS5 is a transmembrane serine protease whose presynaptic distribution on motor neurons in the spinal cord suggests that it is significant for neuronal plasticity. Cell type-specific alternative splicing gives this protease diverse functions by modulating its intracellular localization. Motopsin/PRSS12 is a mosaic protease, and loss of its function causes mental retardation. Recent reports indicate the significance of this protease for cognitive function. We mention the fibrinolytic protease, tissue plasminogen activator (tPA), which has physiological and pathological functions in the CNS.

Full Text Available This article displays a chronological journey of some of the sources of Roman Law that allows us to establish the concept of the “due performance” in Rome. To this extent, we proceed to a reflection of the modifications and adjustments occurred regarding the concept of solutio, during archaic and classical Roman law. Therefore, we will focus on the exegetical study of some other Roman sources, which contains references to solutio, solvere and satisfactio, in order to establish through this path, the structural antecedent of the current notion of “due performance of obligations”.

Sensitive radioimmunosorbent assay for the detection of plant viruses. [Cauliflower mosaic virus, lettuce mosaic virus

1980-06-01

A simple and highly sensitive radioimmunosorbent assay (RISA) for the detection of plant viruses is described. The RISA procedure is a microplate method based on the principle of 'double-antibody sandwich' and follows essentially the protocol of the enzyme-linked immunosorbent assay (ELISA) (Clark and Adams, 1977), with the exception that /sup 125/I-labelled ..gamma..-globulin is substituted for the ..gamma..-globulin enzyme conjugate; the bound /sup 125/I-..gamma..-globulin is dissociated by acidification from the double-antibody sandwich. The radioactivity is proportional to virus concentration, and cauliflower mosaic virus (CaMV) and lettuce mosaic virus (LMV) could be detected at concentrations as low as 5 and 2 ng/ml, respectively. Direct evidence of the adverse effects of conjugation with enzyme on the binding abilities of antibodies is presented. The RISA procedure should prove valuable with viruses for which the ELISA values are too low to be dependable.

Collagen 6-related dystrophies and myopathies (COL6-RD) are a group of disorders that form a wide phenotypic spectrum, ranging from severe Ullrich congenital muscular dystrophy, intermediate phenotypes, to the milder Bethlem myopathy. Both inter- and intrafamilial variable expressivity are commonly observed. We present clinical, immunohistochemical, and genetic data on four COL6-RD families with marked intergenerational phenotypic heterogeneity. This variable expression seemingly masquerades as anticipation is due to parental mosaicism for a dominant mutation, with subsequent full inheritance and penetrance of the mutation in the heterozygous offspring. We also present an additional fifth simplex patient identified as a mosaic carrier. Parental mosaicism was confirmed in the four families through quantitative analysis of the ratio of mutant versus wild-type allele (COL6A1, COL6A2, and COL6A3) in genomic DNA from various tissues, including blood, dermal fibroblasts, and saliva. Consistent with somatic mosaicism, parental samples had lower ratios of mutant versus wild-type allele compared with the fully heterozygote offspring. However, there was notable variability of the mutant allele levels between tissues tested, ranging from 16% (saliva) to 43% (fibroblasts) in one mosaic father. This is the first report demonstrating mosaicism as a cause of intrafamilial/intergenerational variability of COL6-RD, and suggests that sporadic and parental mosaicism may be more common than previously suspected. © 2014 WILEY PERIODICALS, INC.

New Multibeam Bathymetry Mosaic at NOAA/NCEI

Varner, J. D.; Cartwright, J.; Rosenberg, A. M.; Amante, C.; Sutherland, M.; Jencks, J. H.

2017-12-01

NOAA's National Centers for Environmental Information (NCEI) maintains an ever-growing archive of multibeam bathymetric data acquired from U.S. and international government and academic sources. The data are partitioned in the individual survey files in which they were originally received, and are stored in various formats not directly accessible by popular analysis and visualization tools. In order to improve the discoverability and accessibility of the data, NCEI created a new Multibeam Bathymetry Mosaic. Each survey was gridded at 3 arcsecond cell size and organized in an ArcGIS mosaic dataset, which was published as a set of standards-based web services usable in desktop GIS and web clients. In addition to providing a "seamless" grid of all surveys, a filter can be applied to isolate individual surveys. Both depth values in meters and shaded relief visualizations are available. The product represents the current state of the archive; no QA/QC was performed on the data before being incorporated, and the mosaic will be updated incrementally as new surveys are added to the archive. We expect the mosaic will address customer needs for visualization/extraction that existing tools (e.g. NCEI's AutoGrid) are unable to meet, and also assist data managers in identifying problem surveys, missing data, quality control issues, etc. This project complements existing efforts such as the Global Multi-Resolution Topography Data Synthesis (GMRT) at LDEO. Comprehensive visual displays of bathymetric data holdings are invaluable tools for seafloor mapping initiatives, such as Seabed 2030, that will aid in minimizing data collection redundancies and ensuring that valuable data are made available to the broadest community.

The nonagon as a tool for the drawing of the Roman Theatre of Lecce

Giampiero Mele

2015-07-01

Full Text Available  The signs of the Roman city of Lupiae, current Lecce, are many and among them the most noteworthy is the Roman Theatre. The monument has been accidentally discovered during the excavations for the foundations of a house in 1929  and it is located short distance from another landmark of the Roman Lecce: the amphitheatre. The chance of utilizing a the latest threedimensional technology for the detection of the  ruins was an opportunity to study the model of the survey obtained. The analysis of the latter reveals a mismatch with the instructions in “De Architectura” by Vitruvius and shows a particular use of the nonagon for the  design of its iconography. This study aims to compare the hypothesis obtained from the analysis of the metrological survey with the rules explained in the work of Vitruvio to underline similarities and differences between theory and practice.

Fire mosaics and reptile conservation in a fire-prone region.

2013-04-01

Fire influences the distribution of fauna in terrestrial biomes throughout the world. Use of fire to achieve a mosaic of vegetation in different stages of succession after burning (i.e., patch-mosaic burning) is a dominant conservation practice in many regions. Despite this, knowledge of how the spatial attributes of vegetation mosaics created by fire affect fauna is extremely scarce, and it is unclear what kind of mosaic land managers should aim to achieve. We selected 28 landscapes (each 12.6 km(2) ) that varied in the spatial extent and diversity of vegetation succession after fire in a 104,000 km(2) area in the semiarid region of southeastern Australia. We surveyed for reptiles at 280 sites nested within the 28 landscapes. The landscape-level occurrence of 9 of the 22 species modeled was associated with the spatial extent of vegetation age classes created by fire. Biogeographic context and the extent of a vegetation type influenced 7 and 4 species, respectively. No species were associated with the diversity of vegetation ages within a landscape. Negative relations between reptile occurrence and both extent of recently burned vegetation (≤10 years postfire, n = 6) and long unburned vegetation (>35 years postfire, n = 4) suggested that a coarse-grained mosaic of areas (e.g. >1000 ha) of midsuccessional vegetation (11-35 years postfire) may support the fire-sensitive reptile species we modeled. This age class coincides with a peak in spinifex cover, a keystone structure for reptiles in semiarid and arid Australia. Maintaining over the long term a coarse-grained mosaic of large areas of midsuccessional vegetation in mallee ecosystems will need to be balanced against the short-term negative effects of large fires on many reptile species and a documented preference by species from other taxonomic groups, particularly birds, for older vegetation. © 2012 Society for Conservation Biology.

Extended image differencing for change detection in UAV video mosaics

Science.gov (United States)

Saur, Günter; Krüger, Wolfgang; Schumann, Arne

2014-03-01

Change detection is one of the most important tasks when using unmanned aerial vehicles (UAV) for video reconnaissance and surveillance. We address changes of short time scale, i.e. the observations are taken in time distances from several minutes up to a few hours. Each observation is a short video sequence acquired by the UAV in near-nadir view and the relevant changes are, e.g., recently parked or moved vehicles. In this paper we extend our previous approach of image differencing for single video frames to video mosaics. A precise image-to-image registration combined with a robust matching approach is needed to stitch the video frames to a mosaic. Additionally, this matching algorithm is applied to mosaic pairs in order to align them to a common geometry. The resulting registered video mosaic pairs are the input of the change detection procedure based on extended image differencing. A change mask is generated by an adaptive threshold applied to a linear combination of difference images of intensity and gradient magnitude. The change detection algorithm has to distinguish between relevant and non-relevant changes. Examples for non-relevant changes are stereo disparity at 3D structures of the scene, changed size of shadows, and compression or transmission artifacts. The special effects of video mosaicking such as geometric distortions and artifacts at moving objects have to be considered, too. In our experiments we analyze the influence of these effects on the change detection results by considering several scenes. The results show that for video mosaics this task is more difficult than for single video frames. Therefore, we extended the image registration by estimating an elastic transformation using a thin plate spline approach. The results for mosaics are comparable to that of single video frames and are useful for interactive image exploitation due to a larger scene coverage.

Full Text Available Characterization ofCymbidium mosaic virus (CymMV on Orchid Plant Orchids are affected by more virus disease problems than most crops, reducing their commercial values considerably. Orchid viruses are widespread in cultivated orchids, withCymbidium mosaic potexvirus (CymMV being the most prevalent. CymMV high incidence in cultivated orchids has been attributed to the stability and ease of transmission of this virus through cultural practices. CymMV induces floral and foliar necrosis. The virus also reduce plant vigor and lower flower quality, which affect their economic value. The objective of the research is to characterize the virus causing mosaic or chlorotic and necrotic on orchids in West Java. A reverse transcription-polymerase chain reaction (RT- PCR assays using oligonucleotide primers specific to CymMV were also successfully amplified the regions of the coat protein (CP gene of the virus. Analysis by using sodium dodecyl sulphate- polyacrylamide gel electrophoresis (SDS-PAGE revealed that the virus have a major structural protein with an estimated molecular weight of 28 kDa. Aligments of partial nucleotide sequences of the CP gene displayed 86 to 92% homology to CymMV isolates from other countries.

Full Text Available Cultural routes appear as a new concept that turned to be very beneficial in terms of the revitalization and presentation of cultural heritage in its broader sense - from archaeological sites to landscapes. These trails provide a unique purview into the spirit of modern countries and their inextricable connection to contemporary time. On the territory of present day Serbia 17 Roman emperors were born, which is one fifth and largest number of Roman emperors born anywhere in the world, outside of Rome. That was a good basis for developing idea of forming cultural route and starting the project „The Trail of the Roman Emperors“ in Serbia. It can be one of the most important topics in the field of cultural tourism in Serbia, and the main goal of this paper is to give a proposal for its valorization and promotion for the tourism purposes. This will be achieved through the evaluation of all elements of tourist valorization on the basis of which general tourist assessment will be formed, while the purpose of SWOT analysis was to detect existing strengths and weaknesses, and provide real opportunities and risks for this cultural route

Full Text Available As from the 6th century BC Graeco-Roman medical therapy comprised three components, viz. diet and healthy lifestyle (regimen, surgery and medicaments (pharmacotherapy, of which the latter was the oldest. Although the Corpus Hippocraticum (5th century BC, with minor Egyptian influence, contained no text of medicines as such, and seemed to prefer regimen to medicaments, it nevertheless laid the foundation for the empirical use of pharmacotherapy (free of superstition and magic for the next millennium. The first Greek herbal was produced by Diocles in the 4th century BC, when the botanist Theophrastus also wrote his classic works on plants which contained a significant contribution on herbal medicines. The Alexandrian Medical School systematized and expanded Hippocratic medicine, and Herophilus introduced compound preparations. The concept that medicaments cure illness by restoring the bodily balance of humours and primary properties was largely perpetuated, but new views on physiology were gradually emerging. Unfortunately the bulk of original contributions from Hellenistic doctors are lost to posterity and only known to us through the writings of for example Celsus and Galen in Roman times. The interesting history of theriac, the so-called universal antidote, is reviewed. In the 1st century Dioscorides produced his Materia Medica which remained an authoritative pharmacopoeia up to modern times. Galen’s empiric views on pharmacotherapy (2nd century, still largely based on Hippocrates, became dogma in Medieval times, but mysticism and superstition gradually swept back into medicine. Retrospectively it is clear that with the exception of certain analgesics and narcotics like opium, Graeco-Roman medicaments were pharmacologically inert (even toxic and obtained positive results largely through a placebo effect.

Image Mosaic Method Based on SIFT Features of Line Segment

Directory of Open Access Journals (Sweden)

Jun Zhu

2014-01-01

Full Text Available This paper proposes a novel image mosaic method based on SIFT (Scale Invariant Feature Transform feature of line segment, aiming to resolve incident scaling, rotation, changes in lighting condition, and so on between two images in the panoramic image mosaic process. This method firstly uses Harris corner detection operator to detect key points. Secondly, it constructs directed line segments, describes them with SIFT feature, and matches those directed segments to acquire rough point matching. Finally, Ransac method is used to eliminate wrong pairs in order to accomplish image mosaic. The results from experiment based on four pairs of images show that our method has strong robustness for resolution, lighting, rotation, and scaling.

CRISPR-Cas9 is a powerful new tool for genome editing, but this technique creates mosaic mutations that affect the efficiency and precision of its ability to edit the genome. Reducing mosaic mutations is particularly important for gene therapy and precision genome editing. Although the mechanisms underlying the CRSIPR/Cas9-mediated mosaic mutations remain elusive, the prolonged expression and activity of Cas9 in embryos could contribute to mosaicism in DNA mutations. Here we report that tagging Cas9 with ubiquitin-proteasomal degradation signals can facilitate the degradation of Cas9 in non-human primate embryos. Using embryo-splitting approach, we found that shortening the half-life of Cas9 in fertilized zygotes reduces mosaic mutations and increases its ability to modify genomes in non-human primate embryos. Also, injection of modified Cas9 in one-cell embryos leads to live monkeys with the targeted gene modifications. Our findings suggest that modifying Cas9 activity can be an effective strategy to enhance precision genome editing. PMID:28155910

Mosaic Turner syndrome and hyperinsulinaemic hypoglycaemia

DEFF Research Database (Denmark)

Alkhayyat, H.; Christesen, Henrik Thybo; Steer, J.

2006-01-01

BACKGROUND: A common and well recognised feature of Turner's syndrome (partial or total monosomy X) is impaired glucose tolerance or type 2 diabetes mellitus. A small percentage of patients with Turner's syndrome have a complex mosaic karyotype with atypical clinical features and mental retardation....... METHODS/PATIENT: We report the first case of a child with a complex mosaic Turner genotype and hyperinsulinaemic hypoglycaemia responsive to diazoxide therapy. RESULTS: Cytogenetic analysis showed four cell lines: one with 45,X; the others with an additional small ring chromosome, a small marker...... chromosome, and both the ring and marker chromosomes, respectively. FISH studies showed the abnormal chromosomes to originate from an X. The X inactivation locus (XIST) was present in the ring, but not in the marker chromosome. CONCLUSIONS: The recognition of hypoglycaemia in children with atypical Turner...

Mosaic Turner syndrome associated with schizophrenia.

Turner syndrome is a sex-chromosome disorder; occurring in 1 in 2,500 female births. There are sporadic few case reports of concomitant Turner syndrome with schizophrenia worldwide. Most Turner females had a 45,X monosomy, whereas the majority of comorbidity between Turner syndrome and schizophrenia had a mosaic karyotype (45,X/46,XX). We present a case of a 21-year-old woman with Turner syndrome, mosaic karyotype (45,X/46,XX), showing mental retardation, hypothyroidism, and schizophrenia. HOPA gene within Xq13 is related to mental retardation, hypothyroidism, and schizophrenia. Our case may be a potential clue which supports the hypothesis for involvement of genes on X chromosome in development of schizophrenia. Further studies including comorbid cases reports are need in order to discern the cause of schizophrenia in patients having Turner syndrome.

Towards Luminescence Dating Of Mosaic Glass

Science.gov (United States)

Galli, A.; Martini, M.; Sibila, E.; Villa, I.

The possibility of dating archaeological glass by means of luminescent techniques has been investigated in recent years, despite the difficulties of this application, mainly linked to the amorphous structure of the material. We focused in particular on mosaic glass, after the encouraging results obtained on byzantine and medieval samples. Further studies were devoted to the comprehension of the luminescent mechanisms in silica glasses, and to the investigation of the relationships between luminescence, colouring or opacifier ions and crystalline phase of the vitreous matrix. The results of a study on the dosimetric characteristics of thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) of a few medieval blue-green mosaic glasses from the San Lorenzo church (Milan) are presented, and the experimental protocols established to identify their suitability for dating are discussed.

We have demonstrated advances in mosaic hybridization that will enable very large format far-infrared detectors. Specifically we have produced electrical detector models via mosaic hybridization yielding superconducting circuit paths by hybridizing separately fabricated sub-units onto a single detector unit. The detector model was made on a 100mm diameter wafer while four model readout quadrant chips were made from a separate 100mm wafer. The individually fabricated parts were hybridized using a flip-chip bonder to assemble the detector-readout stack. Once all of the hybridized readouts were in place, a single, large and thick silicon substrate was placed on the stack and attached with permanent epoxy to provide strength and a Coefficient of Thermal Expansion match to the silicon components underneath. Wirebond pads on the readout chips connect circuits to warm readout electronics; and were used to validate the successful superconducting electrical interconnection of the model mosaic-hybrid detector. This demonstration is directly scalable to 150 mm diameter wafers, enabling pixel areas over ten times the area currently available.

LANDSAT M. S. S. IMAGE MOSAIC OF TUNISIA.

The Landsat mosaic of Tunisia funded by USAID for the Remote Sensing Laboratory, Soils Division, Ministry of Agriculture, Tunisia, was completed by the USGS in September 1983. It is a mixed mosaic associating digital corrections and enhancements to manual mosaicking and corresponding to the Tunisian request for high resolution and the limited available funds. The scenes were processed by the Environmental Research Institute of Michigan, resampling the data geodesically corrected to fit the Universal Transverse Mercator projection using control points from topographic maps at 1:50,000 and 1:100,000 scales available in the U. S. The mosaicking was done in the Eastern Mapping Center under the supervision of the Graphic Arts System Section. The three black and white mosaics were made at the 1:1,000,000 scale and various products generated. They included color film positives at 1:2,000,000 and 1:4,000,000 scales reproducible in the Remote Sensing Laboratory in Tunis and corresponding color prints as well as tricolor prints at various scales from 1:500,000 to 1:2,000,000.

Haploinsufficiency of SOX9, a master gene in chondrogenesis and testis development, leads to the semi-lethal skeletal malformation syndrome campomelic dysplasia (CD), with or without XY sex reversal. We report on two children with CD and a phenotypically normal father, a carrier of a somatic mosaic SOX9 deletion. This is the first report of a mosaic deletion of SOX9; few familial CD cases with germline and somatic mutation mosaicism have been described. Our findings confirm the utility of aCGH and indicate that for a more accurate estimate of the recurrence risk for a completely penetrant autosomal dominant disorder, parental somatic mosaicism should be considered in healthy parents.

The Hellenistic Epigram and the Roman Poets of the Augustan Period

Directory of Open Access Journals (Sweden)

Jelena Isak Kres

2010-07-01

Full Text Available The paper surveys »Greece through Roman eyes« by searching individual Hellenistic literary epigrams for traces of their impact on the Augustan poets, especially on Vergil, but also on Horace, Propertius, Tibullus, and Ovid. The first section focuses on those passages which echo the poetry of the older generation of epigrammatists (4th—3rd century B.C., particularly Callimachus, Posidippus, and Asclepiades, and the second on those which allude to epigrams composed by the younger generation of Greek authors from the archaic and classical periods of Latin literature, such as Damagetus, Dioscorides, Philodemus, and Crinagoras. Besides the echoes of Greek poetry in the Roman poets’ passages, the paper examines in what ways and to what degree Roman history and Roman authors marked such Greek epigrammatists as Antipater of Sidon or Philip of Thessalonica. A key observation seems to be that Roman authors, albeit they may have written epigrams themselves, nevertheless preferred to embed fragments of epigrammatic poetry (or allusions to it in their longer works, as Vergil did in his Eclogues or the Aeneid. One way in which Vergil played on epigrammatic discourse was to include in the Aeneid recognisable motifs from the Hellenistic literary epigram (e.g. by Anyte and Damagetus, and to treat implicitly through these motifs, embedded in a new context, the same thematic problems as the model epigrams did. Another interesting observation is that the (supposed allusions do not refer exclusively to Greek epigrams but sometimes even to epigrammatic discourse within other poetry genres. An example is Vergil’s passage on Daphnis’ death in the Eclogues, which continues, and alludes to, Theocritus’ episode in the Idylls. While Theocritus’ passage on Daphnis’ death imitates the discourse of funerary epigrams in the voice of Thyrsis or Daphnis himself, Vergil’s passage actually contains a kind of rounded-off, spoken mythological epitaph.

Astrology in Ancient Greek and Roman Culture

Campion, Nicholas

2018-04-01

This article deals with astrology in Greek and Roman culture. It considers astrology's theoretical background, technical basis, interpretative conventions, social functions, religious and political uses, and theory of fate, as well as critiques of it. Astrology is the name given to a series of diverse practices based in the idea that the stars, planets, and other celestial phenomena possess significance and meaning for events on Earth. It assumes a link between Earth and sky in which all existence—spiritual, psychological, and physical—is interconnected. Most premodern cultures practiced a form of astrology. A particularly complex variety of it evolved in Mesopotamia in the first and second millennia BCE from where it was imported into the Hellenistic world from the early 4th century BCE onward. There it became attached to three philosophical schools: those pioneered by Plato, Aristotle, and the Stoics, all of which shared the assumption that the cosmos is a single, living, integrated whole. Hellenistic astrology also drew on Egyptian temple culture, especially the belief that the soul could ascend to the stars. By the 1st century CE the belief in the close link between humanity and the stars had become democratized and diversified into a series of practices and schools of thought that ranged across Greek and Roman culture. It was practiced at the imperial court and in the street. It could be used to predict individual destiny, avert undesirable events, and arrange auspicious moments to launch new enterprises. It could advise on financial fortunes or the condition of one's soul. It was conceived of as natural science and justified by physical influences, or considered to be divination, concerned with communication with the gods and goddesses. In some versions the planets were neither influences nor causes of events on Earth, but timing devices, which indicated the ebb and flow of human affairs, like the hands on a modern clock. Astrology had a radical view of

Generation of High-Resolution Geo-referenced Photo-Mosaics From Navigation Data

Optical images of the ocean floor are a rich source of data to understand biological and geological processes. However, due to the attenuation of light in sea water, the area covered by the optical systems is very reduced, and a large number of images are then needed in order to cover an area of interest, as individually they do not provide a global view of the surveyed area. Therefore, generating a composite view (or photo-mosaic) from multiple overlapping images is usually the most practical and flexible solution to visually cover a wide area, allowing the analysis of the site in one single representation of the ocean floor. In most of the camera surveys which are carried out nowadays, some sort of positioning information is available (e.g., USBL, DVL, INS, gyros, etc). If it is a towed camera an estimation of the length of the tether and the mother ship GPS reading could also serve as navigation data. In any case, a photo-mosaic can be build just by taking into account the position and orientation of the camera. On the other hand, most of the regions of interest for the scientific community are quite large (>1Km2) and since better resolution is always required, the final photo-mosaic can be very large (>1,000,000 × 1,000,000 pixels), and cannot be handled by commonly available software. For this reason, we have developed a software package able to load a navigation file and the sequence of acquired images to automatically build a geo-referenced mosaic. This navigated mosaic provides a global view of the interest site, at the maximum available resolution. The developed package includes a viewer, allowing the user to load, view and annotate these geo-referenced photo-mosaics on a personal computer. A software library has been developed to allow the viewer to manage such very big images. Therefore, the size of the resulting mosaic is now only limited by the size of the hard drive. Work is being carried out to apply image processing techniques to the navigated

The Keeling Curve and The Coral Reef Mosaic Project - Introducing the Realities of Climate Change to Educators and Scholars using Mosaic Arts.

Lueker, T.; Chinn, P. W. U.

2014-12-01

In May 2013, The, record of atmospheric CO2 at Mauna Loa, popularly known as "The Keeling Curve" reached 400 ppm for the first time in human history. Among the most sobering consequences of rising CO2 is Ocean Acidification, caused when the excess CO2 emitted from the burning of fossil fuels is absorbed by the surface oceans. The resulting reduction in pH harms stony corals (Scleractinia), and many other calcareous organisms. If civilization continues along the current trajectory of fossil fuel emissions, most coral reef ecosystems are expected to suffer extreme stress or mortality within the lifetime of the next generation. "If we do not reverse current trends in carbon dioxide emissions soon, we will cause the biggest and most rapid change in ocean chemistry since the extinction of the dinosaurs." (www.seaweb.org/getinvolved/oceanvoices/KenCaldeira.php). This looming tragedy is topical among marine scientists, but less appreciated or unknown to the general public, particularly among communities in the tropics where impacts to coral reef ecosystems will be severe. The Coral Reef Mosaic Project grew from my experiences leading education outreach in local schools. Making mosaics is an engaging way to enlighten educators and scholars on the pressing issues of climate change. When taking part in a mural project, students find mosaic art is a fun and rewarding experience that results in a beautiful depiction of a coral reef. Students explore the ecosystem diversity of coral reef inhabitants as they design the mural and piece together a representative environment. They work together as a team to learn the mosaic techniques and then build their own chosen creatures to inhabit the reef. The result is a beautiful and lasting mural for their school or community that provides an important message for the future. In a cooperative project with Dr. Pauline Chin at UH Manoa we traveled to Hawaii to train teachers on the Big Island in the art of mosaic and to convey the

The TOTEM collaboration has developed and tested the first prototype of its Roman Pots to be operated in the LHC. TOTEM Roman Pots contain stacks of 10 silicon detectors with strips oriented in two orthogonal directions. To measure proton scattering angles of a few microradians, the detectors will approach the beam centre to a distance of 10 sigma + 0.5 mm (= 1.3 mm). Dead space near the detector edge is minimised by using two novel "edgeless" detector technologies. The silicon detectors are used both for precise track reconstruction and for triggering. The first full-sized prototypes of both detector technologies as well as their read-out electronics have been developed, built and operated. The tests took place first in a fixed-target muon beam at CERN's SPS, and then in the proton beam-line of the SPS accelerator ring. We present the test beam results demonstrating the successful functionality of the system despite slight technical shortcomings to be improved in the near future.

Somatic mosaicism has been implicated as a causative mechanism in a number of genetic and genomic disorders. X-linked acrogigantism (XLAG) syndrome is a recently characterized genomic form of pediatric gigantism due to aggressive pituitary tumors that is caused by submicroscopic chromosome Xq26.3 duplications that include GPR101 We studied XLAG syndrome patients (n= 18) to determine if somatic mosaicism contributed to the genomic pathophysiology. Eighteen subjects with XLAG syndrome caused by Xq26.3 duplications were identified using high-definition array comparative genomic hybridization (HD-aCGH). We noted that males with XLAG had a decreased log2ratio (LR) compared with expected values, suggesting potential mosaicism, whereas females showed no such decrease. Compared with familial male XLAG cases, sporadic males had more marked evidence for mosaicism, with levels of Xq26.3 duplication between 16.1 and 53.8%. These characteristics were replicated using a novel, personalized breakpoint junction-specific quantification droplet digital polymerase chain reaction (ddPCR) technique. Using a separate ddPCR technique, we studied the feasibility of identifying XLAG syndrome cases in a distinct patient population of 64 unrelated subjects with acromegaly/gigantism, and identified one female gigantism patient who had had increased copy number variation (CNV) threshold for GPR101 that was subsequently diagnosed as having XLAG syndrome on HD-aCGH. Employing a combination of HD-aCGH and novel ddPCR approaches, we have demonstrated, for the first time, that XLAG syndrome can be caused by variable degrees of somatic mosaicism for duplications at chromosome Xq26.3. Somatic mosaicism was shown to occur in sporadic males but not in females with XLAG syndrome, although the clinical characteristics of the disease were similarly severe in both sexes. © 2016 Society for Endocrinology.

Approximately two-thirds of Duchenne muscular dystrophy (DMD) patients have a deletion in the dystrophin gene located at Xp21.1. Two PCR-based multiplex systems have been developed which detect 98% of deletions in affected males. Diagnosis of carrier females requires densitometry of PCR products following gel electrophoresis to calculate dosage of specific exons. We have developed a system in which fluorescently labelled PCR products are analysed using a GENESCANNER automated fragment analyser (ABI). Dosage is determined using computer-assisted laser densitometry (CALD). Recently, we diagnosed somatic mosaicism in the mother of an affected boy using this method. PCR analysis showed that the patient had a deletion that included exons 47-51 of his dystrophin gene. CALD analysis on the patient`s 36-year-old mother revealed a 29-34% reduction in the intensity of the bands corresponding to the deleted region of the gene rather than the 50% reduction normally seen in carrier females. A skin biopsy was obtain and monoclonal fibroblast colonies were tested by CALD for the deletion. Four of the twenty colonies screened were found to be deleted while the remaining colonies had two intact copies of the gene. We conclude that this patient is a somatic mosaic for DMD and that the mutation was the result of a post-zygotic event. This is the only case of somatic mosaicism detected among 800 women from 400 DMD families tested using CALD in our laboratory. At least one other case of possible somatic mosaicism has been reported but not confirmed. Germinal mosaicism is thought to occur in approximately 10% of mothers of sporadic DMD patients. Our findings indicate that somatic mosaicism is a much rarer condition among DMD carriers, thus suggesting that mitotic mutations in the dystrophin gene are more likely to occur later in embryogenesis after differentiation of the germline.

Full Text Available Leaves of twenties radish (Raphanus sativus L. inbred lines were mechanically inoculated with Turnip mosaic virus (TuMV strain HY to evaluate TuMV resistance of the radish inbred lines. The inoculated radish plants were incubated at 22°C±3°C and resistance assessment was examined using symptom development for 4 weeks. Based on the reactions of differential radish inbred lines, 16 radish lines were produced mild mosaic, mottling, mosaic and severe mosaic symptoms by TuMV infection. These results were confirmed by RT-PCR analysis of TuMV coat protein gene, suggesting that TuMV is responsible for the disease symptoms. Four resistant radish lines did not induce systemic mosaic symptoms on upper leaves and chlorosis in stem tissues for 4 weeks, showing they were symptomless by 8 weeks. Further examination of TuMV infection in the 4 radish lines showed no TuMV infection in all systemic leaves. These results suggest that the 4 radish lines are highly resistant to TuMV.

Bypass of lethality with mosaic mice generated by Cre-loxP-mediated recombination.

Betz, U A; Vosshenrich, C A; Rajewsky, K; Müller, W

The analysis of gene function based on the generation of mutant mice by homologous recombination in embryonic stem cells is limited if gene disruption results in embryonic lethality. Mosaic mice, which contain a certain proportion of mutant cells in all organs, allow lethality to be circumvented and the potential of mutant cells to contribute to different cell lineages to be analyzed. To generate mosaic animals, we used the bacteriophage P1-derived Cre-loxP recombination system, which allows gene alteration by Cre-mediated deletion of loxP-flanked gene segments. We generated nestin-cre transgenic mouse lines, which expressed the Cre recombinase under the control of the rat nestin promoter and its second intron enhancer. In crosses to animals carrying a loxP-flanked target gene, partial deletion of the loxP-flanked allele occurred before day 10.5 post coitum and was detectable in all adult organs examined, including germ-line cells. Using this approach, we generated mosaic mice containing cells deficient in the gamma-chain of the interleukin-2 receptor (IL-2R gamma); in these animals, the IL-2R gamma-deficient cells were underrepresented in the thymus and spleen. Because mice deficient in DNA polymerase beta die perinatally, we studied the effects of DNA polymerase beta deficiency in mosaic animals. We found that some of the mosaic polymerase beta-deficient animals were viable, but were often reduced in size and weight. The fraction of DNA polymerase beta-deficient cells in mosaic embryos decreased during embryonic development, presumably because wild-type cells had a competitive advantage. The nestin-cre transgenic mice can be used to generate mosaic animals in which target genes are mutated by Cre-mediated recombination of loxP-flanked target genes. By using mosaic animals, embryonic lethality can be bypassed and cell lineages for whose development a given target gene is critical can be identified. In the case of DNA polymerase beta, deficient cells are already

Ancient Topometry, the Tracing of Towns in the Roman Epoch: Ulpia Traiana Dacica Sarmizegetusa - Romania. Second Part

Science.gov (United States)

Stanescu, Florin

2015-05-01

While following the rituals and the ancient topometrical methods used by the Romans in tracing cities according to the Etruscan tradition, this paper presents the historical, anthropological and archaeological aspects, analyzing techniques being used and aims at determining the day when there was inaugurated after the 2nd Dacian-Roman war, 105-106 AD, the new capital, Colonia Ulpia Traiana Augusta Dacica Sarmizegetusa, of the new province of Roman Empire, "Dacia Felix". The aspects of the problem which require a special archaeoastronomical and archaeometrical analysis are the physical horizon and the sun's movement. The provisional results obtained so far lead to the conclusion that the capital might have been traced in the 15-18 september period, that coincided with Emperor Trajan's birthday.

Traditional and New Enhancing Human Cybernetic and Nanotechnological Body Modification Technologies: A Comparative Study of Roman Catholic and Transhumanist Ethical Approaches

Science.gov (United States)

Caligiuri, Michael J.

Advances in cybernetic and nanotechnological body modifications currently allow for enhancements to human physical and mental function which exceed human species-based norms. This thesis examines body modification and human enhancement from two perspectives---Roman Catholicism and Transhumanism--- in order to contribute to bioethical deliberations regarding enhancement technologies. Roman Catholicism has a longstanding tradition of bioethical discourse, informing the healthcare directives of Roman Catholic institutions. Transhumanism is more recent movement that endorses body modifications and human enhancements as a means of individual betterment and social evolution. The thesis first considers definitions of human enhancement and levels of normalcy in connection to cybernetic and nanotechnological bionic implants, and outlines a series of criteria to assess a technology's potential bioethical acceptability: implantability, permanency, power, and public interaction. The thesis then describes Roman Catholicism's response to non-enhancing decorative body modifications (cosmetic surgeries, common decorative modifications such as tattoos and piercings, and uncommon modifications such as scarifications and brandings) in order to establish a basis for possible Roman Catholic responses to enhancing cybernetic and nanotechnological modifications. This is followed by an analysis from a Roman Catholic perspective of the major social issues brought forward by enhancement technologies: commodification, eugenics, vulnerability, and distributive justice. Turning to Transhumanism, the thesis describes the origins and philosophy of the movement, and then discusses the bioethical principles it advances with regard to human enhancement. The thesis concludes by locating points of convergence between Transhumanism and Roman Catholicism that could be the basis of more widely accepted ethical guidelines regarding modification technologies.

In this study, we propose a novel "mosaic structure" for a SOFC (solid oxide fuel cell) cathode with high thermal expansion to improve the stability against thermal stress. Self-organizing mosaic-shaped cathode has been successfully achieved by controlling the amount of binder in the dip-coating solution. The anode-supported cell with mosaic-shaped cathode shows itself to be highly durable performance for rapid thermal cycles, however, the performance of the cell with a non-mosaic cathode exhibits severe deterioration originated from the delamination at the cathode/electrolyte interface after 7 thermal cycles. The thermal stability of an SOFC cathode can be evidently improved by controlling the surface morphology. In view of the importance of the thermal expansion properties of the cathode, the effects of cathode morphology on the thermal stress stability are discussed.

The protease encoded by the large (B) RNA segment of cowpea mosaic virus was tested for its ability to recognize the in vitro translation products of the small (M) RNA segment from the comoviruses squash mosaic virus, red clover mottle virus, and cowpea severe mosaic virus (CPsMV, strains Dg and Ark), and from the nepovirus tomato black ring virus. Like M RNA from cowpea mosaic virus, the M RNAs from squash mosaic virus, red clover mottle virus, CPsMV-Dg, and CPsMV-Ark were all translated into two large polypeptides with apparent molecular weights which were different for each virus and even for the two CPsMV strains. Neither the in vitro products from squash mosaic virus, red clover mottle virus, and CPsMV M RNAs nor the in vitro product from tomato black ring virus RNA-2 were processed by the cowpea mosaic virus-encoded protease, indicating that the activity of this enzyme is highly specific.

Full Text Available This paper presents the results of a multi-disciplinary provenance study of querns and millstones during the Roman period (1st-4th century CE in the northern part of the Roman Empire (provinces of Gallia Belgica and Germania Inferior. Comparative petrographical, mineralogical and geochemical analysis allowed an international team of archaeologists and geologists to identify the different raw materials used for the manufacturing of querns and millstones. As a result, (litho- stratigraphic assignments as well as geological-geographical provenances are suggested or corroborated for the broad spectrum of these natural geo-materials. We give evidence for the exploitation of at least seven different rock types. They include sedimentary rocks (fine- to coarse-grained quartzitic and arkosic sandstones, conglomerates, limestones and volcanic rocks (vesicular lavas derived from different geological strata in the following geological-geographical settings: the volcanic Eifel area (Pleistocene lava, the Ardennes Massif (Palaeozoic sedimentary rocks and the Paris and Northern Sea Basin (Cenozoic sedimentary rocks. Furthermore we show that a large diversity existed within different productions (different types of hand-mills and mechanical powered mills and distribution patterns. This paper provides new data which will lead to new insights into the socio-economics of the local “Gallo-Roman” communities and into their networks within the northern Roman Empire.

Prenatal diagnosis of a case of X/XXX mosaicism is presented. In spite of the fact that over 50% of the cells cultured from both ovaries were trisomic for the X chromosome, fetal öocytes were rarely found. This case illustrates that the presence of a triple-X cell line, even in a relatively high percentage of ovarian cells, does not necessarily protect the ovary from 'aöogenesis'. This observation might prove useful in the counselling of future cases involving the prenatal detection of sex chromosome mosaicism. Images PMID:856232

We report here a very unusual pelvic calcification recovered from the remains of a 30-40-year-old woman found at the late Roman period archeological site of La Fogonussa (Lleida, Catalonia). Although differential diagnoses for calcifications of the pelvis are complicated in archeological contexts, the precise localization, macroscopic features, and the presence of teeth along with part of a small bone led us to identify this case as an ovarian teratoma, based upon gross observations and computerized tomography (CT).

Hamidson, H.; Damiri, N.; Angraini, E.

2018-01-01

This research was conducted to study the effect of the application of several extracts of medicinal plants on the incidence of mosaic disease caused by Cucumber Mosaic Virus infection on the chili (Capsicum annuum L.) plantation. A Randomized Block Design with eight treatments including control was used throughout the experiment. Treatments consisted of Azadiracta indica (A), Piper bitle (B), Cymbopogon citrates (C), Curcuma domestica (D), Averroa bilimbi (E), Datura stramonium (F), Annona Muricata (G) and control (H). Each treatment consist of three replications. The parameters observed were the incidence of mosaic attack due to CMV, disease severity, plant height, wet and dry weight and production (number of fruits and the weight of total fruits) each plant. Results showed that the application of medicinal plant extracts reduced the disease severity due to CMV. Extracts of Annona muricata and Datura stramonium were most effective in suppressing disease severity caused by the virus as they significantly different from control and from a number of treatment. The plants medicinal extracts were found to have increased the plant height and total weight of the plant, fruit amount and fruit weight. Extracts of Curcuma domestica, Piper bitle and Cymbopogon citrates were the third highest in fruit amount and weight and significantly different from the control.

Real-time construction and visualisation of drift-free video mosaics from unconstrained camera motion

Directory of Open Access Journals (Sweden)

Mateusz Brzeszcz

2015-08-01

Full Text Available This work proposes a novel approach for real-time video mosaicking facilitating drift-free mosaic construction and visualisation, with integrated frame blending and redundancy management, that is shown to be flexible to a range of varying mosaic scenarios. The approach supports unconstrained camera motion with in-sequence loop closing, variation in camera focal distance (zoom and recovery from video sequence breaks. Real-time performance, over extended duration sequences, is realised via novel aspects of frame management within the mosaic representation and thus avoiding the high data redundancy associated with temporally dense, spatially overlapping video frame inputs. This managed set of image frames is visualised in real time using a dynamic mosaic representation of overlapping textured graphics primitives in place of the traditional globally constructed, and hence frequently reconstructed, mosaic image. Within this formulation, subsequent optimisation occurring during online construction can thus efficiency adjust relative frame positions via simple primitive position transforms. Effective visualisation is similarly facilitated by online inter-frame blending to overcome the illumination and colour variance associated with modern camera hardware. The evaluation illustrates overall robustness in video mosaic construction under a diverse range of conditions including indoor and outdoor environments, varying illumination and presence of in-scene motion on varying computational platforms.

In the era of the diseasomes and interactome networks, linking genetics with phenotypic traits in Turner syndrome should be studied thoroughly. As a part of this stratagem, mosaicism of both X and Y chromosome which is a common finding in TS and an evaluation of congenital heart diseases in the different situations of mosaic TS types, can be helpful in the identification of disturbed sex chromosomes, genes and signaling pathway actors. Here we report the case of a mosaic TS associated to four left-sided CHD, including BAV, COA, aortic aneurysms and dissections at an early age. The mosaicism included two cell lines, well-defined at the cytogenetic and molecular levels: a cell line which is monosomic for Xp and Xq genes (45,X) and another which is trisomic for pseudoautosomal genes that are present on the X and Y chromosomes and escape X inactivation: 45,X[8]/46,X,idic(Y)(pter→q11.2::q11.2→pter)[42]. This case generates two hypotheses about the contribution of genes linked to the sex chromosomes and the signaling pathways involving these genes, in left-sided heart diseases. The first hypothesis suggests the interaction between X chromosome and autosomal genes or loci of aortic development, possibly dose-dependent, and which could be in the framework of TGF-β-SMAD signaling pathways. The second implies that left-sided congenital heart lesions involve sex chromosomes loci. The reduced dosage of X chromosome gene(s), escaping X inactivation during development, contributes to this type of CHD. Regarding our case, these X chromosome genes may have homologues at the Y chromosome, but the process of inactivation of the centromeres of the isodicentric Y spreads to the concerned Y chromosome genes. Therefore, this case emerges as an invitation to consider the mosaics of Turner syndrome and to study their phenotypes in correlation with their genotypes to discover the underlying developmental and genetic mechanisms, especially the ones related to sex chromosomes.

Candidate mosaic proteins for a pan-filoviral cytotoxic T-Cell lymphocyte vaccine

The extremely high fatality rates of many filovirus (FILV) strains the recurrent but rarely identified origin of human epidemics, the only partly identified viral reservoirs and the continuing non-human primate epizootics in Africa make a broadly-protective filovirus vaccine highly desirable. Cytotoxic T-cells (CTL) have been shown to be protective in mice, guinea pigs and non-human primates. In murine models the cytotoxic T-cell epitopes that are protective against Ebola virus have been mapped and in non-human primates CTL-mediated protection between viral strains (John Dye: specify) has been demonstrated using two filoviral proteins, nucleoprotein (NP) and glycoprotein (GP). These immunological results suggest that the CTL avenue of immunity deserves consideration for a vaccine. The poorly-understood viral reservoirs means that it is difficult to predict what strains are likely to cause epidemics. Thus, there is a premium on developing a pan-filoviral vaccine. The genetic diversity of FILV is large, roughly the same scale as human immunodeficiency virus (HIV). This presents a serious challenge for the vaccine designer because a traditional vaccine aspiring to pan-filoviral coverage is likely to require the inclusion of many antigenic reagents. A recent method for optimizing cytotoxic T-cell lymphocyte epitope coverage with mosaic antigens was successful in improving potential CTL epitope coverage against HIV and may be useful in the context of very different viruses, such as the filoviruses discussed here. Mosaic proteins are recombinants composed of fragments of wild-type proteins joined at locations resulting in exclusively natural k-mers, 9 {le} k {le} 15, and having approximately the same length as the wild-type proteins. The use of mosaic antigens is motivated by three conjectures: (1) optimizing a mosaic protein to maximize coverage of k-mers found in a set of reference proteins will give better odds of including broadly-protective CTL epitopes in a vaccine

Mosaic nanocomposites composed of nickel and cobalt nanowires arranged in different configurations were investigated using Monte Carlo simulations and a simple model that considers single-domain structures including length corrections due to the shape anisotropy. Our results showed that for an ordered array both the coercivity and the remanence decrease linearly as a function of the concentration of nickel nanowires. Besides, we obtained that the magnetic properties of an array of a certain hard magnetic material (cobalt) will not change, unless we have more than 50% of nanowires of other soft magnetic material (nickel) in the array. In principle the second material could be other soft magnetic material, but could also be a nonmagnetic material or could even be a situation in which some of the pore arrays were not filled by electrodeposition. Therefore, our results allow us to predict the behavior of magnetic mosaic nanocomposites that are promising candidates for functional electrodes, sensors, and model catalysts. - Highlights: • Mosaic nanocomposites composed of magnetic nanowires were investigated. • Magnetic properties can be adjusted by varying the concentration of nanowires. • Our results allow us to predict the behavior of magnetic mosaic nanocomposites.

We describe the case of a ten-year-old girl with short stature and 45,X/47,XXX genotype. She also suffered from vesicoureteric reflux and kidney dysfunction prior to having surgery on her ureters. Otherwise, she does not have any of the characteristics of Turner nor Triple X syndrome. It has been shown that this mosaic condition as well as other varieties creates a milder phenotype than typical Turner syndrome, which is what we mostly see in our patient. However, this patient is a special case, because she is exceptionally short. Overall, one cannot predict the resultant phenotype in these mosaic conditions. This creates difficulty in counseling parents whose children or fetuses have these karyotypes.

Transparent 3D Visualization of Archaeological Remains in Roman Site in Ankara-Turkey with Ground Penetrating Radar Method Selma KADIOGLU Ankara University, Faculty of Engineering, Department of Geophysical Engineering, 06100 Tandogan/ANKARA-TURKEY kadioglu@eng.ankara.edu.tr Anatolia has always been more the point of transit, a bridge between West and East. Anatolia has been a home for ideas moving from all directions. So it is that in the Roman and post-Roman periods the role of Anatolia in general and of Ancyra (the Roman name of Ankara) in particular was of the greatest importance. Now, the visible archaeological remains of Roman period in Ankara are Roman Bath, Gymnasium, the Temple of Augustus of Rome, Street, Theatre, City Defence-Wall. The Caesar Augustus, the first Roman Emperor, conquered Asia Minor in 25 BC. Then a marble temple was built in Ancyra, the administrative capital of province, today the capital of Turkish Republic, Ankara. This monument was consecrated to the Empreror and to the Goddess Rome. This temple is supposed to have built over an earlier temple dedicated to Kybele and Men between 25 -20 BC. After the death of the Augustus in 14AD, a copy of the text of "Res Gestae Divi Augusti" was inscribed on the interior of the pronaos in Latin, whereas a Greek translation is also present on an exterior wall of the cella. In the 5th century, it was converted in to a church by the Byzantines. The aim of this study is to determine old buried archaeological remains in the Augustus temple, Roman Bath and in the governorship agora in Ulus district. These remains were imaged with transparent three dimensional (3D) visualization of the ground penetrating radar (GPR) data. Parallel two dimensional (2D) GPR profile data were acquired in the study areas, and then a 3D data volume were built using parallel 2D GPR data. A simplified amplitude-colour range and appropriate opacity function were constructed and transparent 3D image were obtained to activate buried

Ploidy mosaicism and allele-specific gene expression differences in the allopolyploid Squalius alburnoides

2011-12-01

Full Text Available Abstract Background Squalius alburnoides is an Iberian cyprinid fish resulting from an interspecific hybridisation between Squalius pyrenaicus females (P genome and males of an unknown Anaecypris hispanica-like species (A genome. S. alburnoides is an allopolyploid hybridogenetic complex, which makes it a likely candidate for ploidy mosaicism occurrence, and is also an interesting model to address questions about gene expression regulation and genomic interactions. Indeed, it was previously suggested that in S. alburnoides triploids (PAA composition silencing of one of the three alleles (mainly of the P allele occurs. However, not a whole haplome is inactivated but a more or less random inactivation of alleles varying between individuals and even between organs of the same fish was seen. In this work we intended to correlate expression differences between individuals and/or between organs to the occurrence of mosaicism, evaluating if mosaics could explain previous observations and its impact on the assessment of gene expression patterns. Results To achieve our goal, we developed flow cytometry and cell sorting protocols for this system generating more homogenous cellular and transcriptional samples. With this set-up we detected 10% ploidy mosaicism within the S. alburnoides complex, and determined the allelic expression profiles of ubiquitously expressed genes (rpl8; gapdh and β-actin in cells from liver and kidney of mosaic and non-mosaic individuals coming from different rivers over a wide geographic range. Conclusions Ploidy mosaicism occurs sporadically within the S. alburnoides complex, but in a frequency significantly higher than reported for other organisms. Moreover, we could exclude the influence of this phenomenon on the detection of variable allelic expression profiles of ubiquitously expressed genes (rpl8; gapdh and β-actin in cells from liver and kidney of triploid individuals. Finally, we determined that the expression patterns

Vroue, nasie en verwoording in Sharai Mukonoweshuro se Shona-romans

Full Text Available Die doel van hierdie artikel is om die fiktiewe voorstelling van vroue in twee van Sharai Mukonoweshuro se romans, naamlik Ndakagara Ndazviona en Akafuratidzwa Moyo, te verken. Tradisionele Shona verwagtinge van hoe ’n vrou moet optree, skryf die rolle voor wat van vroue verwag word om in die samelewing te speel. In ’n koloniale konteks soos die voormalige Rhodesië het kolonialisme wette in die gewoontereg bedink wat vroue verder gedegradeer het tot sosiale posisies soortgelyk aan dié van minderjariges. Hoewel die nasionalistiese stryd in wese bedoel was om vryheid te waarborg vir alle Swart mense, ongeag van geslag, het die manlike elites Swart vroue as hul minderwaardige ‘ander‘ gekonstrueer. In hierdie artikel word geargumenteer dat Sharai Mukonoweshuro se romans worstel met hierdie manlik-goedgekeurde stereotipes. Maar, soos getoon word, Mukonoweshuro se wyse van weerstand teen vroulike stereotipes is ambivalent; die skrywer skep jong vroue wat die patriargie aan die een kant uitdaag, en aan die ander kant, ou vroue wat die ondenkbare doen om hulle eie seuns te vergiftig.

Full Text Available A mosaic disease of pumpkin (Cucurbita maxima was spread widely in Sulawesi. Since the virus had not yet been identified, a study was conducted to identify the disease through mechanical inoculation, aphid vector transmission, host range, and electron microscopic test. Crude sap of infected pumpkin leaf samples was rubbed on the cotyledons of healthy pumpkin seedlings for mechanical inoculation. For insect transmission, five infective aphids were infected per seedling. Seedlings of eleven different species were inoculated mechanically for host range test. Clarified sap was examined under the electron microscope. Seeds of two pumpkin fruits from two different infected plants were planted and observed for disease transmission up to one-month old seedlings. The mosaic disease was transmitted mechanically from crude sap of different leaf samples to healthy pumpkin seedlings showing mosaic symptoms. The virus also infected eight cucurbits, i.e., cucumber (Cucumis sativus, green melon (Cucumis melo, orange/rock melon (C. melo, zucchini (Cucurbita pepo, pumpkin (Cucurbita maxima, water melon (Citrulus vulgaris, Bennicosa hispida, and blewah (Cucurbita sp.. Aphids  transmitted the disease from one to other pumpkin seedlings. The virus was not transmitted by seed. The mosaic disease of pumpkin at Maros, South Sulawesi, was associated with flexious particles of approximately 750 nm length, possibly a potyvirus, such as water melon mosaic virus rather than papaya ringspot virus or zucchini yellow mosaic virus.

Transcriptome sequencing of two phenotypic mosaic Eucalyptus trees reveals large scale transcriptome re-modelling.

Directory of Open Access Journals (Sweden)

Amanda Padovan

Full Text Available Phenotypic mosaic trees offer an ideal system for studying differential gene expression. We have investigated two mosaic eucalypt trees from two closely related species (Eucalyptus melliodora and E. sideroxylon, which each support two types of leaves: one part of the canopy is resistant to insect herbivory and the remaining leaves are susceptible. Driving this ecological distinction are differences in plant secondary metabolites. We used these phenotypic mosaics to investigate genome wide patterns of foliar gene expression with the aim of identifying patterns of differential gene expression and the somatic mutation(s that lead to this phenotypic mosaicism. We sequenced the mRNA pool from leaves of the resistant and susceptible ecotypes from both mosaic eucalypts using the Illumina HiSeq 2000 platform. We found large differences in pathway regulation and gene expression between the ecotypes of each mosaic. The expression of the genes in the MVA and MEP pathways is reflected by variation in leaf chemistry, however this is not the case for the terpene synthases. Apart from the terpene biosynthetic pathway, there are several other metabolic pathways that are differentially regulated between the two ecotypes, suggesting there is much more phenotypic diversity than has been described. Despite the close relationship between the two species, they show large differences in the global patterns of gene and pathway regulation.

Somatic mosaicism has been implicated as a causative mechanism in a number of genetic and genomic disorders. X-linked acrogigantism (XLAG) syndrome is a recently characterized genomic form of pediatric gigantism due to aggressive pituitary tumors that is caused by submicroscopic chromosome Xq26.3 duplications that include GPR101. We studied XLAG syndrome patients (N=18) to determine if somatic mosaicism contributed to the genomic pathophysiology. Eighteen subjects with XLAG syndrome were identified with Xq26.3 duplications using high definition array comparative genome hybridization (HD-aCGH). We noted males with XLAG had a decreased log2 ratio compared with expected values, suggesting potential mosaicism, while females showed no such decrease. As compared with familial male XLAG cases, sporadic males had more marked evidence for mosaicism, with levels of Xq26.3 duplication between 16.1-53.8%. These characteristics were replicated using a novel, personalized breakpoint-junction specific quantification droplet digital PCR (ddPCR) technique. Using a separate ddPCR technique we studied the feasibility of identifying XLAG syndrome cases in a distinct patient population of 64 unrelated subjects with acromegaly/gigantism and identified one female gigantism patient that had increased copy number variation (CNV) threshold for GPR101 that was subsequently diagnosed as having XLAG syndrome on HD-aCGH. Employing a combination of HD-aCGH and novel ddPCR approaches, we have demonstrated, for the first time, that XLAG syndrome can be caused by variable degrees of somatic mosaicism for duplications at chromosome Xq26.3. Somatic mosaicism was shown to occur in sporadic males but not in females with XLAG syndrome, although the clinical characteristics of the disease were similarly severe in both sexes. PMID:26935837

CHARGE syndrome is an autosomal dominant malformation syndrome caused by mutations in the CHD7 gene. The majority of cases are sporadic and only few familial cases have been reported. In these families, mosaicism in one parent, as well as parent- to-child transmission of a CHD7 mutation, has been described. In some further cases, germline mosaicism has been suggested. Here, we report the first case in which germline mosaicism could be demonstrated in a father of two affected children with CHARGE syndrome. The truncating mutation c.7302dupA in exon 34 of the CHD7 gene was found in both affected children but was not detected in parental lymphocytes. However, in DNA extracted from the father's spermatozoa, the c.7302dupA mutation could be identified. Furthermore, mutation analysis of DNA isolated from 59 single spermatozoa revealed that the c.7302dupA mutation occurs in 16 spermatozoa, confirming germline mosaicism in the father of the affected children. This result has a high impact for genetic counselling of the family and for their recurrence risk in further pregnancies.

Quantitative analyses of various silver coins from the firs century BC, found on current Romanian territory (Thasian tetradrachmae, Apollonia and Dyrrachium drachmae, Roman republican denarii) were performed using PIXE (3 MeV external proton beam) and XRF (1.1 GBq 241 Am source). The elemental analysis provided evidence of a great variety of monetary alloys and helped Romanian archaeologists to classify the coins, in terms of their provenance, as originals, copies or imitations minted in different areas of the Balkan-Carpathian region.

A sap transmissible virus, causing mosaic and leaf curl disease of Celosia argentea, was isolated at vegetable farms in Amuwo Odofin, Tejuoso, and Abule Ado, Lagos, Nigeria. The virus had a restricted host range confined to a few species of the Amaranthaceae, Chenopodiaceae and Solanaceae families. It failed to infect several other species of the Aizoaceae, Brassicaceae, Cucurbitaceae, Fabaceae, Lamiaceae, Malvaceae, Poaceae and Tiliaceae families. The virus was transmitted in a non-persistent manner by Aphis spiraecola and Toxoptera citricidus but not by eight other aphid species tested. There was no evidence of transmission by seeds of C. argentae varieties. The viral coat protein had a relative molecular mass (M(r)) of about 30.2 K. Electron microscopy of purified virus preparations revealed flexuous rod shaped particles of about 750 nm in length. Serological studies were performed using the enzyme-linked immunosorbent assay (ELISA), immunosorbent electron microscopy (ISEM) and Western blot analysis. The virus reacted positively with an universal potyvirus group monoclonal antibody (MoAb) and MoAb P-3-3H8 raised against peanut stripe potyvirus. It also reacted with polyclonal antibodies raised against several potyviruses including asparagus virus-1 (AV-1), turnip mosaic virus (TuMV), maize dwarf mosaic virus (MDMV), watermelon mosaic virus (WMV-2), plum pox virus (PPV), soybean mosaic virus (SoyMV), lettuce mosaic virus (LMV), bean common mosaic virus (BCMV) and beet mosaic virus (BMV) in at least one of the serological assays used. On the basis of host range, mode of transmission, and available literature data, the celosia virus seems to be different from potyviruses previously reported to infect vegetables in Nigeria. The name celosia mosaic virus (CIMV) has been proposed for this virus.

Age-associated bone loss and intraskeletal variability in the Imperial Romans.

Science.gov (United States)

Cho, Helen; Stout, Sam Darrel

2011-01-01

An Imperial Roman sample from the Isola Sacra necropolis (100-300 A.D.) offered an opportunity to histologically examine bone loss and intraskeletal variability in an urban archaeological population. Rib and femur samples were analyzed for static indices of bone remodeling and measures of bone mass. The Imperial Romans experienced normal age-associated bone loss via increased intracortical porosity and endosteal expansion, with females exhibiting greater bone loss and bone turnover rates than in males. Life events such as menopause and lactation coupled with cultural attitudes and practices regarding gender and food may have led to increased bone loss in females. Remodeling dynamics differ between the rib and femur and the higher remodeling rates in the rib may be attributed to different effective age of the adult compacta or loading environment. This study demonstrates that combining multiple methodologies to examine bone loss is necessary to shed light on the biocultural factors that influence bone mass and bone loss.

A double-voiced reading of Romans 13:1–7 in light of the imperial cult

Directory of Open Access Journals (Sweden)

Sung U. Lim

2015-03-01

Full Text Available Drawing on Mikhail Bakhtin’s theory of double-voicedness and James Scott’s theory of public and hidden transcripts, this essay investigates the colonial context of Romans 13:1–7 with particular attention to the Roman imperial cult. It is my contention that Paul attempts to persuade the audience to resist the imperial cult, whilst negotiating colonial power and authority. It is assumed that colonial discourse is, by nature, a double-voiced discourse in that the public transcript of the dominant and the hidden transcript of the suppressed coexist in a continued state of internal tension and conflict. Seen in this light, Paul as a colonised subject parodies the public transcript of the elites in his own hidden transcript. However, Paul’s doubled-voiced discourse finally turns out to be subversive against the dominant culture by suggesting that ultimate honour, fear, and authority should not be due to the rulers of the Roman Empire but to God.

Chromosomal mosaicism in mouse two-cell embryos after paternal exposure to acrylamide

Energy Technology Data Exchange (ETDEWEB)

Marchetti, Francesco; Bishop, Jack; Lowe, Xiu; Wyrobek, Andrew J

2008-10-14

Chromosomal mosaicism in human preimplantation embryos is a common cause ofspontaneous abortions, however, our knowledge of its etiology is limited. We used multicolor fluorescence in situ hybridization (FISH) painting to investigate whether paternally-transmitted chromosomal aberrations result in mosaicism in mouse 2-cell embryos. Paternal exposure to acrylamide, an important industrial chemical also found in tobacco smoke and generated during the cooking process of starchy foods, produced significant increases in chromosomally defective 2-cell embryos, however, the effects were transient primarily affecting the postmeiotic stages of spermatogenesis. Comparisons with our previous study of zygotes demonstrated similar frequencies of chromosomally abnormal zygotes and 2-cell embryos suggesting that there was no apparent selection against numerical or structural chromosomal aberrations. However, the majority of affected 2-cell embryos were mosaics showing different chromosomal abnormalities in the two blastomeric metaphases. Analyses of chromosomal aberrations in zygotes and 2-cell embryos showed a tendency for loss of acentric fragments during the first mitotic division ofembryogenesis, while both dicentrics and translocations apparently underwent propersegregation. These results suggest that embryonic development can proceed up to the end of the second cell cycle of development in the presence of abnormal paternal chromosomes and that even dicentrics can persist through cell division. The high incidence of chromosomally mosaic 2-cell embryos suggests that the first mitotic division of embryogenesis is prone to missegregation errors and that paternally-transmitted chromosomal abnromalities increase the risk of missegregation leading to embryonic mosaicism.

[Preliminary data of life and health insurance in the Roman Law (The collegium funeraticium and the collegium tenuiorum)].

Váradi, Agnes

2007-12-30

With the explosion of insurance contracts in the last two hundred years both in Europe and around the rest of the world, there is a temptation to think that the financing and insuring on projects on limited or non-recourse terms is a relatively novel concept. This is, however, far from being true. Indeed, there is an early evidence of project financing techniques and insurance contracts being actively used during the ancient times. The first examples come from the Roman law but there are similar legal institutions even in the ancient Greek legal system. - The essay analyses the legal history of assurances on lives and health in the Roman law, especially the question of the collegium tenuiorum and the collegium funeraticium. In the centre of the studies are the analyses of their legal personality, the changes in the regulation concerning their foundation, the purpose and the internal organisation. The treatment of the main topics begins with fragments from the material of the Corpus Iuris Civilis by Justinian. After that the views of the most important authors and the contemporary investigations in the Roman law found the statements of the paper. As a result of these analyses we can see the process of development in the ancient legal systems, especially in the Roman law. And although these results have no immediate influence on the present legal regulation, it can demonstrate original tendencies in the field of insurances. This way we can prove that the Roman law is a still existing basis for the development in contractual law.

Concurrent insulinoma with mosaic Turner syndrome: A case report.

2015-03-01

Turner syndrome is a chromosomal abnormality in which the majority of patients have a 45XO karyotype, while a small number have a 45XO/47XXX karyotype. Congenital adrenal hyperplasia has been previously reported in patients with Turner syndrome. Although insulinomas are the most common type of functioning pancreatic neuroendocrine tumor and have been reported in patients with multiple endocrine neoplasias, the tumors have not been reported in patients with mosaic Turner syndrome. The present study reports the first case of an insulinoma in a patient with 45XO/47XXX mosaic Turner syndrome. The patient suffered from recurrent hypoglycemia, which was relieved following ingestion of glucose or food. A 5-h glucose tolerance test was performed and the levels of glucose, C-Peptide and insulin were detected. In addition, computed tomography (CT) and ultrasound scanning were performed to evaluate the possibility of an insulinoma. Pathological examination and karyotyping were performed on a surgical specimen and a whole blood sample, respectively. The patient was found to suffer from premature ovarian failure, and a physical examination was consistent with a diagnosis of Turner syndrome. An ultrasound scan demonstrated streak ovaries and the patient was found to have a 45XO/47XXX karyotype. Furthermore, a lesion was detected in the pancreas following CT scanning, which was identified as an insulinoma following surgical removal and histological examination. In conclusion, the present study reports the first case of an insulinoma in a patient with mosaic Turner syndrome. Since mosaic Turner syndrome and insulinoma are rare diseases, an association may exist that has not been previously identified.

Learning and gaining knowledge of Roman history is an area of interest for students and citizens at large. This is an example of a subject with great sweep (with many interrelated sub-topics over, in this case, a 3,000 year history) that is hard to grasp by any individual and, in its full detail, is not available as a coherent story. In this paper, we propose a visual analytics approach to construct a data driven view of Roman history based on a large collection of Wikipedia articles. Extracting and enabling the discovery of useful knowledge on events, places, times, and their connections from large amounts of textual data has always been a challenging task. To this aim, we introduce VAiRoma, a visual analytics system that couples state-of-the-art text analysis methods with an intuitive visual interface to help users make sense of events, places, times, and more importantly, the relationships between them. VAiRoma goes beyond textual content exploration, as it permits users to compare, make connections, and externalize the findings all within the visual interface. As a result, VAiRoma allows users to learn and create new knowledge regarding Roman history in an informed way. We evaluated VAiRoma with 16 participants through a user study, with the task being to learn about roman piazzas through finding relevant articles and new relationships. Our study results showed that the VAiRoma system enables the participants to find more relevant articles and connections compared to Web searches and literature search conducted in a roman library. Subjective feedback on VAiRoma was also very positive. In addition, we ran two case studies that demonstrate how VAiRoma can be used for deeper analysis, permitting the rapid discovery and analysis of a small number of key documents even when the original collection contains hundreds of thousands of documents.

MOSAIC: An organic geochemical and sedimentological database for marine surface sediments

Modern ocean sediments serve as the interface between the biosphere and the geosphere, play a key role in biogeochemical cycles and provide a window on how contemporary processes are written into the sedimentary record. Research over past decades has resulted in a wealth of information on the content and composition of organic matter in marine sediments, with ever-more sophisticated techniques continuing to yield information of greater detail and as an accelerating pace. However, there has been no attempt to synthesize this wealth of information. We are establishing a new database that incorporates information relevant to local, regional and global-scale assessment of the content, source and fate of organic materials accumulating in contemporary marine sediments. In the MOSAIC (Modern Ocean Sediment Archive and Inventory of Carbon) database, particular emphasis is placed on molecular and isotopic information, coupled with relevant contextual information (e.g., sedimentological properties) relevant to elucidating factors that influence the efficiency and nature of organic matter burial. The main features of MOSAIC include: (i) Emphasis on continental margin sediments as major loci of carbon burial, and as the interface between terrestrial and oceanic realms; (ii) Bulk to molecular-level organic geochemical properties and parameters, including concentration and isotopic compositions; (iii) Inclusion of extensive contextual data regarding the depositional setting, in particular with respect to sedimentological and redox characteristics. The ultimate goal is to create an open-access instrument, available on the web, to be utilized for research and education by the international community who can both contribute to, and interrogate the database. The submission will be accomplished by means of a pre-configured table available on the MOSAIC webpage. The information on the filled tables will be checked and eventually imported, via the Structural Query Language (SQL), into

INTERCOMPRENSIONE: LA STRADA DEL DIALOGO INTERCULTURALE ATTRAVERSO L’ANALISI DI ITINERAIRES ROMANS

Full Text Available L'Unione Europea ha posto il multilinguismo come elemento centrale della propria politica linguistica e aspira al raggiungimento di una situazione in cui ciascun cittadino conosca almeno due lingue comunitarie oltre alla propria madrelingua. Per raggiungere questo obiettivo esiste una vasta gamma di modelli di educazione plurilingue. L'articolo prende in considerazione l'intercomprensione, ossia l'apprendimento  ricettivo di più lingue attraverso lo sviluppo di strategie che facilitino la trasferibilità di meccanismi cognitivi, conoscenze e abilità già acquisite da una lingua all'altra e analizza Itinéraires Romans un progetto realizzato dall'Unione latina, un'organizzazione fondata per valorizzare l'eredità culturale e le identità del mondo latino. Itinéraires Romans è un progetto didattico on line rivolto ai ragazzi della scuola primaria di secondo grado che riunisce una serie di sei moduli su tematiche diverse aventi come obiettivo la stimolazione dei giovani internauti a scoprire i legami che esistono tra le lingue neolatine. Le lingue coinvolte sono: il catalano, lo spagnolo, l'italiano, il francese, il portoghese e il rumeno.   The European Union has made multilingualism a central element of its linguistic policy and it aspires to create the conditions so that every citizen knows at least two EU languages besides their mother tongue.  To reach this goal, there is a vast range of models for plurilingual education. This paper focuses on intercomprehension, or the receptive learning of several languages through the development of strategies which facilitate the transferability of cognitive mechanisms, knowledge and skills already mastered from one language to another.  It analyzes Itinéraires Romans, a project implemented by the Latin Union.  This organization was founded to enhance the cultural inheritance and the identity of the Latin world. Itinéraires Romans is an on-line didactic project for 3rd,4th and 5th grade students

Identification of Prader-Willi Syndrome mosaicism by fluorescent in situ hybridization

Prader-Willi Syndrome (PWS) is a microdeletion syndrome involving an interstitial deletion of region q11-q13 on the paternal chromosome 15. We report 2 cases of PWS that were analyzed using FISH and were found to be mosaic for a normal cell line and a deleted cell line. Case 1 was diagnosed as an atypical PWS who was cytogenetically normal. She is a 38 y.o. white female displaying some but not all of the features of PWS. Case 2 is a 23 y.o. white male with a classical deletion of chromosome 15q11-q13. He displays very typical features of PWS. He was also noted to be albino. FISH analysis was performed on PHA stimulated lymphocytes. We examined four loci: D15S11, SNRPN, D15S10, and GABRB3. The number of cells examined for each locus ranged from 46 to 75. Case 1 was deleted at 3 of the 4 loci (D15S11, SNRPN and GABRB3) in 30% of her cells. The D15S10 locus was not deleted. This may account for the atypical features displayed by this patient. It also suggests that this chromosome is rearranged resulting in the retention of the interstitial locus. The exact nature of the rearrangement needs to be determined. Case 2 was deleted at all four loci in 60% of the cells analyzed. This result was unexpected because his deletion was identified cytogenetically, but mosaicism was not detected. These are the first reported cases of mosaic PWS diagnosed using FISH. The use of cytogenetics alone requires high resolution banding to accurately identify the deletion. This makes the detection of small deletions in every cell difficult and the determination of mosaicism almost impossible. Our results suggest that mosaicism may be occurring more frequently than previously thought and may account for some of the atypical cases. Studies are in progress to determine the effect of mosaicism on methylation at genes located within this region which are imprinted and are thought to be involved in the etiology of Prader-Willi Syndroms.

The Roman Synodal Letter Confi dimus Quidem in the Context of Relations Between the Churches of East and West (370–379

Directory of Open Access Journals (Sweden)

Zakharov Georgii

2016-08-01

Full Text Available The article is devoted to the reconstruction of the project of the Arian crisis’s resolution proposed by the Roman and Italian Churches to the local Churches of Illyricum and East (370(1. According to the author, this project was fixed in the letter of one of the Roman councils in the pontificate of Pope Damasus I (366–384, known as Confi dimus quidem. This text was originally perceived with little enthusiasm by eastern Neo-Nicene bishops and probably also by St. Athanasius the Great, because it attempted to supplement the Nicene creed by theological formula expressed in Latin theological categories. In particular, the letter used the concept of substantia, which could be translated into Greek, not only as οuσία, but also as uπόστασις, while the eastern Neo-Nicene bishops insisted on the distinction between these terms. In addition, in the text there were elements of the ecclesiological conception of Roman centralism. For example the letter proclaims the dependence of ecumenical council decisions’ authority from its reception by Roman bishop. The Church of Rome, apparently, regarded Confi dimus quidem as a document which had to endorse any bishop who wanted to be received in Roman communion. In 379, the Council of Antioch included Confi dimus quidem in the collection of approved Roman doctrinal fragments. This action probably helped to restore communion between the eastern and western Nicene bishops.

Parcours d’un roman postcolonial francophone en France et en Allemagne : Le Cœur des enfants léopards, de Wilfried N’Sondé

Full Text Available En 2007, Wilfried N’Sondé, Franco-congolais vivant à Berlin, publie en France son premier roman, Le Cœur des enfants léopards. Le livre rencontre un certain succès. Un an plus tard, la traduction allemande, Das Herz der Leopardenkinder semble faire une carrière comparable en Allemagne. On serait donc tenté de conclure qu’il n’y a pas tant de différence entre le lectorat français et le lectorat allemand. Un bon roman est un bon roman et il semble normal qu’il trouve son public des deux côtés du Rhin... Mais à y regarder de plus près, il apparaît que la réception du roman de Wilfried N’Sondé en France et en Allemagne suit des voies bien différentes. En France, les littératures postcoloniales sont essentiellement considérées à l’intérieur du cadre conceptuel de la francophonie et le roman de N’Sondé apparaît effectivement d’abord comme un roman francophone ; en Allemagne, il est plutôt rattaché à la littérature de la migration et est compris en fonction des traditions d’analyse qui s’y rattachent.2007 veröffentlicht der in Berlin lebende und aus Kongo stammende Franzose Wilfried N’Sondé, seinen ersten Roman, Le cœur des enfants léopards. Das Buch erfreut sich in Frankreich einer regen Aufmerksamkeit. Ein Jahr später scheint die deutsche Übersetzung, Das Herz der Leopardenkinder, am französischen Erfolg anzuknüpfen : ein guter Roman bleibt ein guter Roman und so scheint es nur normal dass, er auf beiden Seiten des Rheins sein Publikum findet. Dennoch wäre es falsch, daraus auf eine sehr ähnliche Leserschaft in den beiden Sprachräumen zu schließen. Bei genauerem Hinsehen zeigt sich, dass die Rezeption von Wilfried N’Sondés Roman in Frankreich und in Deutschland sehr unterschiedlich verläuft. Während der Roman in Frankreich im Kontext der postkolonialen Literatur in erster Linie als frankophones Werk rezipiert wird, konzentriert sich die deutsche Rezeption vornehmlich auf den

Early embryonic chromosome instability results in stable mosaic pattern in human tissues.

Directory of Open Access Journals (Sweden)

Hasmik Mkrtchyan

Full Text Available The discovery of copy number variations (CNV in the human genome opened new perspectives on the study of the genetic causes of inherited disorders and the aetiology of common diseases. Here, a single-cell-level investigation of CNV in different human tissues led us to uncover the phenomenon of mitotically derived genomic mosaicism, which is stable in different cell types of one individual. The CNV mosaic ratios were different between the 10 individuals studied. However, they were stable in the T lymphocytes, immortalized B lymphoblastoid cells, and skin fibroblasts analyzed in each individual. Because these cell types have a common origin in the connective tissues, we suggest that mitotic changes in CNV regions may happen early during embryonic development and occur only once, after which the stable mosaic ratio is maintained throughout the differentiated tissues. This concept is further supported by a unique study of immortalized B lymphoblastoid cell lines obtained with 20 year difference from two subjects. We provide the first evidence of somatic mosaicism for CNV, with stable variation ratios in different cell types of one individual leading to the hypothesis of early embryonic chromosome instability resulting in stable mosaic pattern in human tissues. This concept has the potential to open new perspectives in personalized genetic diagnostics and can explain genetic phenomena like diminished penetrance in autosomal dominant diseases. We propose that further genomic studies should focus on the single-cell level, to better understand the aetiology of aging and diseases mediated by somatic mutations.

Full Text Available Mapping archeological sites using digital cartography. Roman settlements from potaissa to Napoca. We aim to analyze and correct several archaeological and historical data regarding some settlements included in an official document, issued by the Ministry of Culture from Romania, entitled the List of Historical Monuments (Lista Monumentelor Istorice / LMI. We focused our attention on the Roman road from Potaissa to Napoca, the main imperial road of Dacia. We described the route of the Roman road and corrected the old information in the list of historical monuments regarding the discoveries within the territory of the village of Aiton. Methodologically, we used data from the old literature, the modern Austro-Hungarian maps from the XVIIIth and the XIXth centuries, information from regional gazetteers and different journals. We aimed to offer new insights regarding the accurate location of these settlements and to debate upon the spatial relations of these settlements and their position within the landscape of Dacia. At the beginning of the study, we presented the present situation concerning the databases in Romania covering archaeological sites. The second part of our study discusses how the archaeological sites are recorded in the list of historical monuments. Then we offered several case studies This type of methodological approach will be applied in the future for other areas, in order to reconstruct the former landscape of the province of Dacia, as accurately as possible, using digital tools and modern maps. Our contribution also improved the quality of the data sets used for the topographical descriptions of archaeological sites in Romania.

Causes of chromosomal nondisjunction is one of the remaining unanswered questions in human genetics. In order to increase our understanding of the mechanisms underlying nondisjunction we have performed a molecular study on trisomy 8 and trisomy 8 mosaicism. We report the results on analyses of 26 probands (and parents) using 19 microsatellite DNA markers mapping along the length of chromosome 8. The 26 cases represented 20 live births, four spontaneous abortions, and two prenatal diagnoses (CVS). The results of the nondisjunction studies show that 20 cases (13 maternal, 7 paternal) were probably due to mitotic (postzygotic) duplication as reduction to homozygosity of all informative markers was observed and as no third allele was ever detected. Only two cases from spontaneous abortions were due to maternal meiotic nondisjunction. In four cases we were not able to detect the extra chromosome due to a low level of mosaicism. These results are in contrast to the common autosomal trisomies (including mosaics), where the majority of cases are due to errors in maternal meiosis.

This paper describes the development of a digital spatial library based on mosaics of digital orthophotos, called Interactive Portugal, that will enable users both to retrieve geospatial information existing in the Portuguese National System for Geographic Information World Wide Web server, and to develop local databases connected to the main system. A set of navigation, interaction, and visualization tools are proposed and discussed. They include sketching, dynamic sketching, and navigation capabilities over the digital orthophotos mosaics. Main applications of this digital spatial library are pointed out and discussed, namely for education, professional, and tourism markets. Future developments are considered. These developments are related to user reactions, technological advancements, and projects that also aim at delivering and exploring digital imagery on the World Wide Web. Future capabilities for site selection and change detection are also considered.

Mosaic deletion of 20pter due to rescue by somatic recombination.

Science.gov (United States)

Martin, Megan M; Vanzo, Rena J; Sdano, Mallory R; Baxter, Adrianne L; South, Sarah T

2016-01-01

We report on a unique case of a mosaic 20pter-p13 deletion due to a somatic repair event identified by allele differentiating single nucleotide polymorphism (SNP) probes on chromosomal microarray. Small terminal deletions of 20p have been reported in a few individuals and appear to result in a variable phenotype. This patient was a 24-month-old female who presented with failure to thrive and speech delay. Chromosomal microarray analysis (CMA) performed on peripheral blood showed a 1.6 Mb deletion involving the terminus of 20p (20pter-20p13). This deletion appeared mosaic by CMA and this suspicion was confirmed by fluorescence in situ hybridization (FISH) analysis. Additionally, the deletion interval at 20p was directly adjacent to 15 Mb of mosaic copy-neutral loss of heterozygosity (LOH). The pattern of SNP probes was highly suggestive of a somatic repair event that resulted in rescue of the deleted region using the non-deleted homologue as a template. Structural mosaicism is rare and most often believed to be due to a postzygotic mechanism. This case demonstrates the additional utility of allele patterns to help distinguish mechanisms and in this case identified the possibility of either a post-zygotic repair of a germline deletion or a post-zygotic deletion with somatic recombination repair in a single step. © 2015 Wiley Periodicals, Inc.

[A space for women in the Etruscan and Roman houses (VI-I cent. B.C.)?].

Science.gov (United States)

Jolivet, Vincent

2011-01-01

The article analyzes the scientific discussion about the existence of a domestic space reserved to women in Etruscan and Roman houses. The hypotesis regarding the existence of a 'gynaeceum' has been recently proposed for the Etruscan houses built on Palatino in Rome (VI cent. B.C.) and for the ancient phase of the Centaurus Protodomus in Pompei. Considering the specific role of Roman matronae as laniferae, and also a substantial equality of social role between Etruscan men and women, it is possible to advance the hypotesis of the existence of a room originally reserved to women (oecus) on one side of the tablinum, the symmetrical room being reserved to men (triclinium).

gmos: Rapid Detection of Genome Mosaicism over Short Evolutionary Distances.

Prokaryotic and viral genomes are often altered by recombination and horizontal gene transfer. The existing methods for detecting recombination are primarily aimed at viral genomes or sets of loci, since the expensive computation of underlying statistical models often hinders the comparison of complete prokaryotic genomes. As an alternative, alignment-free solutions are more efficient, but cannot map (align) a query to subject genomes. To address this problem, we have developed gmos (Genome MOsaic Structure), a new program that determines the mosaic structure of query genomes when compared to a set of closely related subject genomes. The program first computes local alignments between query and subject genomes and then reconstructs the query mosaic structure by choosing the best local alignment for each query region. To accomplish the analysis quickly, the program mostly relies on pairwise alignments and constructs multiple sequence alignments over short overlapping subject regions only when necessary. This fine-tuned implementation achieves an efficiency comparable to an alignment-free tool. The program performs well for simulated and real data sets of closely related genomes and can be used for fast recombination detection; for instance, when a new prokaryotic pathogen is discovered. As an example, gmos was used to detect genome mosaicism in a pathogenic Enterococcus faecium strain compared to seven closely related genomes. The analysis took less than two minutes on a single 2.1 GHz processor. The output is available in fasta format and can be visualized using an accessory program, gmosDraw (freely available with gmos).

The study area is located at S. Agata (Gera Lario), a small center at the northern end of Como Lake, near the junction of Valchiavenna and Valtellina Valleys. This site played a strategic role since ancient times, providing the control on the communications routes to both the Como Lake and the Spluga and Septimer alpine passes. Since the end of the last century archaeological findings are reported in literature, also supported, from the early XI century, by archival documents confirming the existence of the `Olonium' settlement, an administrative and fiscal center of primary importance, as well as a parish amongst the most influential in the Como Lake area. Within an area of 45,000 m 2 an electrical survey has been carried out in conjunction with magnetic and GPR investigations. These studies have indicated the presence of a number of sub-areas characterized by significant anomalies defined by the overlapping of the results obtained from two or more geophysical methods. In two of such sub-areas, excavation tests have been conducted, which have brought to light a number of archaeological findings of interest. In one of the two sub-areas, which is characterized by the superimposition of electrical and radar anomalies, a deposit of large pebbles has been found. The origin of this deposit has not been ascertained, whether it is of fluvial origin, related to the deviation of the Adda river in the Pian di Spagna region in Roman times, or it is part of reclamation works, still of Roman times, of paleolacustrine marshes. The overlapping stratigraphy, however, suggests the development of fluvial channels between Roman and Low-Medieval times. In the other sub-area, excavations were carried out on sites defined by electrical and radar anomalies, and confirmed by the results from magnetic survey. The excavations brought to light, below the fluvial deposits, a large medieval edifice, which could be identified as the S. Stefano church abandoned in 1444. The church is built on

[The Antonine Plague and the decline of the Roman Empire].

Science.gov (United States)

Sabbatani, S; Fiorino, S

2009-12-01

The Antonine Plague, which flared up during the reign of Marcus Aurelius from 165 AD and continued under the rule of his son Commodus, played such a major role that the pathocenosis in the Ancient World was changed. The spread of the epidemic was favoured by the occurrence of two military episodes in which Marcus Aurelius himself took part: the Parthian War in Mesopotamia and the wars against the Marcomanni in northeastern Italy, in Noricum and in Pannonia. Accounts of the clinical features of the epidemic are scant and disjointed, with the main source being Galen, who witnessed the plague. Unfortunately, the great physician provides us with only a brief presentation of the disease, his aim being to supply therapeutic approaches, thus passing over the accurate description of the disease symptoms. Although the reports of some clinical cases treated by Galen lead us to think that the Antonine plague was caused by smallpox, palaeopathological confirmation is lacking. Some archaeological evidence (such as terracotta finds) from Italy might reinforce this opinion. In these finds, some details can be observed, suggesting the artist's purpose to represent the classic smallpox pustules, typical signs of the disease. The extent of the epidemic has been extensively debated: the majority of authors agree that the impact of the plague was severe, influencing military conscription, the agricultural and urban economy, and depleting the coffers of the State. The Antonine plague affected ancient Roman traditions, also leaving a mark on artistic expression; a renewal of spirituality and religiousness was recorded. These events created the conditions for the spread of monotheistic religions, such as Mithraism and Christianity. This period, characterized by health, social and economic crises, paved the way for the entry into the Empire of neighbouring barbarian tribes and the recruitment of barbarian troops into the Roman army; these events particularly favoured the cultural and

Normal X-inactivation mosaicism in corneas of heterozygous FlnaDilp2/+ female mice--a model of human Filamin A (FLNA diseases

Directory of Open Access Journals (Sweden)

Douvaras Panagiotis

2012-02-01

Full Text Available Abstract Background Some abnormalities of mouse corneal epithelial maintenance can be identified by the atypical mosaic patterns they produce in X-chromosome inactivation mosaics and chimeras. Human FLNA/+ females, heterozygous for X-linked, filamin A gene (FLNA mutations, display a range of disorders and X-inactivation mosaicism is sometimes quantitatively unbalanced. FlnaDilp2/+ mice, heterozygous for an X-linked filamin A (Flna nonsense mutation have variable eye, skeletal and other abnormalities, but X-inactivation mosaicism has not been investigated. The aim of this study was to determine whether X-inactivation mosaicism in the corneal epithelia of FlnaDilp2/+ mice was affected in any way that might predict abnormal corneal epithelial maintenance. Results X-chromosome inactivation mosaicism was studied in the corneal epithelium and a control tissue (liver of FlnaDilp2/+ and wild-type (WT female X-inactivation mosaics, hemizygous for the X-linked, LacZ reporter H253 transgene, using β-galactosidase histochemical staining. The corneal epithelia of FlnaDilp2/+ and WT X-inactivation mosaics showed similar radial, striped patterns, implying epithelial cell movement was not disrupted in FlnaDilp2/+ corneas. Corrected stripe numbers declined with age overall (but not significantly for either genotype individually, consistent with previous reports suggesting an age-related reduction in stem cell function. Corrected stripe numbers were not reduced in FlnaDilp2/+ compared with WT X-inactivation mosaics and mosaicism was not significantly more unbalanced in the corneal epithelia or livers of FlnaDilp2/+ than wild-type Flna+/+ X-inactivation mosaics. Conclusions Mosaic analysis identified no major effect of the mouse FlnaDilp2 mutation on corneal epithelial maintenance or the balance of X-inactivation mosaicism in the corneal epithelium or liver.

The Roman Law of Talion and its correlative origin: antiquity and innovation

Directory of Open Access Journals (Sweden)

2017-09-01

Full Text Available The Law of Talion is usually understood as «an eye for an eye». However, Roman law is far from being as concise and strict as that of the Bible. Whilst not forgetting the option of membrum pro membro, the interpretation of Latin examples tells us that punishments tended to be comparable and not equal, materially speaking, to the harm caused. The linguistic analysis of talio, derived from the indefinite talis and the correlative structure (quale scelus, talis poena in which it appears, leads us to see this feminine substantive of action as a neologism of proportional reference that encouraged Roman law to evolve towards substitute punishments that were less gory. In order to understand the spirit of the Law of Talion, we must take into consideration its form, which above all is made up of the indefinite talis as a correlative of qualis referring to the damage or harm caused.

“Apostolic” and “Imperial” discourse in the development of the Roman Primacy in the 4th century

Directory of Open Access Journals (Sweden)

Zakharov Georgii

2016-07-01

Full Text Available The article is devoted to the evolution of the Roman primacy in the 4th century. The Christianization of the Empire accelerated the process of regional consolidation of the episcopate, but did not lead to the emergence of specific «imperial ecclesiology». At the same time in the 4th century, traditional apostolic ecclesiology has maintained its position both in the West and the East. We can distinguish two different types of the apostolic ecclesiology: locally-historical (the doctrine of St. Irenaeus and Tertullian and universally-hierarchical (the concept of St. Cyprian of Carthage. The first can be fi nd in the works of pope Julius, St. Athanasius and in the letter of the council of Constantinople (382, the second — in the texts of St. Basil the Great and Palladius of Ratiara. At the same time on the council of Serdica (343 Western bishops supported the new “Roman” ecclesiological model. They proclaimed the Roman See as the Chair of Peter the only center of catholic communion and invested it with special legal prerogatives. In fact, this model was the result of ecclesiological synthesis of two early conceptions of apostolicity: the idea of apostolic origins of the Roman Church was connected with the idea of the primacy of Peter as the basis of the Church’s unity. In the future, this conception was adopted by the bishop of Rome. Pope Damasus I (366–384, developing the doctrine of the Roman See as sedes apostolica, actually put principle of Roman primacy above the principle of synodal consensus. Eastern bishops did not support this interpretation of the church order, defending the autonomy of the Eastern Churches. They proclaimed Constantinople New Rome, in fact, denying the uniqueness of the status of the Church of Rome.

Translating Romans: some persistent headaches

Directory of Open Access Journals (Sweden)

A.B. du Toit

2010-07-01

Full Text Available Translating Romans: some persistent headaches Gone are the days when it was axiomatic that expertise in biblical languages automatically qualified one as a Bible translator. In 1949, Ronald Knox, who for nine years conscientiously struggled with translating the Bible for his generation, published a booklet under the title The trials of a translator. At that stage Bible translation as the subject of scientific study was still in its infancy. Since then, research into the intricacies of communicating the biblical message in an authentic but understandable manner, has made significant progress (cf. Roberts, 2009. However, the frustrations of Bible translators, first of all to really understand what the biblical authors wanted to convey to their original addressees, and then to commu-nicate that message to their own targeted readers in a meaningful way, have not disappeared. In fact, the challenge to meet the vary-ing requirements of the multiple kinds of translation that are present-ly in vogue, has only increased.

LHC Report: a Roman potpourri

CERN Multimedia

Mike Lamont for the LHC Team

2012-01-01

The last couple of weeks of operation have been a mixed bag, with time dedicated to TOTEM and ALFA, a floating machine development period and luminosity calibration runs. These special running periods were interleaved with some standard proton running where we’ve struggled a little to recover previous highs. The LHC has now returned to more routine operation.   The TOTEM and ALFA run required the development of special optics to produce large beam sizes and smaller angular spread at the interaction points in ATLAS and CMS. These special optics produce shallower angled proton-proton collisions than normal and thus allow experiments to probe the very small angle scattering regime.

The Roman Road System in the Golan: Highways, Paths and Tracks in Quotidian Life

Directory of Open Access Journals (Sweden)

Full Text Available Roman Imperial Roads (highways built, maintained and organized by the Roman army and provincial authorities were studied in the Golan Heights since Schumacher’s surveys in the 1880s. However, most of these were obliterated by building and agricultural activity since the beginning of the 20th century. Local ancient road system, linking individual communities and their agricultural land was never studied, since it barely leaves a trace in archaeological record. This paper presents reconstruction of inter-provincial highways passing through the southern Golan Heights, and local road system in GIS using cumulative focal mobility network (CFMN analysis. The CFMN provides outline of natural corridors of movement in the region. From CFMN it is possible to extract path with higher mobility potential which will be tested against present evidence for Roman Imperial Highways, since it is assumed that corridors with high mobility potential would be suitable place for construction of (inter-provincial road. Path with lower mobility potential might indicate local road system, so it would be possible to connect agricultural communities with the land they exploited; which in turn may have implications for site prediction and site-catchment analysis exploring quotidian movement of people and goods in the landscape. Two case studies in this respect are presented: the city of Hippos and settlement of es-Safuriyye.

Carbonation kinetics in roman-like lime mortar

Directory of Open Access Journals (Sweden)

Sánchez-Moral, S.

2004-09-01

Full Text Available The kinetic parameterisation of lime mortar carbonation is a useful technique for understanding ancient building methods and the long-lived physical-chemical stability of roman monuments. Portlandite (Ca(OH₂ binders harden in the air on contact with atmospheric CO₂, producing CaCO₃. Water evaporation and the presence of silicate aggregates have a three-fold effect: prompting the development of a pore system that permits CO₂, self-diffusion, reducing shrinkage and cracking during drying and (possibly giving rise to subsequent pozzolanic reactions. The present survey involved air-hardening a series of roman-like lime mortars which differed in terms of: (i type of aggregate, volcanic tephra and arkose; (ii aggregate/binder ratio, 1:2 as used in the catacombs and 1:4 as found in standard roman construction and (iii temperature, the 17 ºC prevailing in underground environments and the 30 ºC typical of warm Mediterranean areas. The analyses that provided the most useful information were performed in a classic X-ray diffractometer adapted to accommodate an author-designed chamber in which temperature control was achieved by an internal refrigerant and a PID-governed electrical heater Additional data were obtained with DTA and environmental scanning electron microscopy (ESEM. The tests conducted on the Roman-like lime mortars manufactured for the experiment showed that the hardening temperature is a critical factor in the initial phases of carbonation. Calcite precipitation rates and total mineral precipitation increased with temperature, but fell very quickly as calcite precipitated. In theoretical calculations assuming an open reactor with continuous CO₂, input, total calcitisation time was found to be 156 m in. at 30 ºC and 175 min. at 17 ºC, whilst in the mortars actually hardened in the experimental part of the study, calcitisation gradually blocked the flow or CO₂, gas into the

The primary skeletal tissue in elasmobranchs -sharks, rays and relatives- is cartilage, forming both embryonic and adult endoskeletons. Only the skeletal surface calcifies, exhibiting mineralized tiles (tesserae) sandwiched between a cartilage core and overlying fibrous perichondrium. These two tissues are based on different collagens (Coll II and I, respectively), fueling a long-standing debate as to whether tesserae are more like calcified cartilage or bone (Coll 1-based) in their matrix composition. We demonstrate that stingray (Urobatis halleri) tesserae are bipartite, having an upper Coll I-based 'cap' that merges into a lower Coll II-based 'body' zone, although tesserae are surrounded by cartilage. We identify a 'supratesseral' unmineralized cartilage layer, between tesserae and perichondrium, distinguished from the cartilage core in containing Coll I and X (a common marker for mammalian mineralization), in addition to Coll II. Chondrocytes within tesserae appear intact and sit in lacunae filled with Coll II-based matrix, suggesting tesserae originate in cartilage, despite comprising a diversity of collagens. Intertesseral joints are also complex in their collagenous composition, being similar to supratesseral cartilage closer to the perichondrium, but containing unidentified fibrils nearer the cartilage core. Our results indicate a unique potential for tessellated cartilage in skeletal biology research, since it lacks features believed diagnostic for vertebrate cartilage mineralization (e.g. hypertrophic and apoptotic chondrocytes), while offering morphologies amenable for investigating the regulation of complex mineralized ultrastructure and tissues patterned on multiple collagens.

2014-08-30

Blueberry mosaic disease (BMD) was first described more than 60 years ago and is caused by a yet unidentified graft transmissible agent. A combination of traditional methods and next generation sequencing disclosed the presence of a new ophiovirus in symptomatic plants. The virus was detected in all BMD samples collected from several production areas of North America and was thus named blueberry mosaic associated virus. Phylogenetic analysis, supported by high bootstrap values, places the virus within the family Ophioviridae. The genome organization resembles that of citrus psorosis virus, the type member of the genus Ophiovirus. The implications of this discovery in BMD control and blueberry virus certification schemes are also discussed. Copyright © 2014 Elsevier B.V. All rights reserved.

A set of Roman glass fragments, excavated at Sevilla and dated in the 5th century A.D., has been analysed by PIXE and PIGE techniques using the external beam set-up of the 3 MV tandem Pelletron accelerator of the CNA at the University of Sevilla. Using a simple quantification method, based on the indirect charge calculation on the sample by monitoring the X-ray induced by the proton beam on the exit window, the composition of the glasses has been determined. From the obtained results, the use of soda as flux has been inferred and colouring manufacture procedures have been identified.

Patients with Turner syndrome are generally characterized by having short stature with no secondary sexual characteristics. Some abnormalities, such as webbed neck, renal malformations (>50%) and cardiac defects (10%) are less common. The intelligence of these patients is considered normal. Non-mosaic monosomy X is observed in approximately 45% of postnatal patients with Turner syndrome and the rest of the patients have structural abnormalities or mosaicism involving 46,X,i(Xq), 45,X/46,XX, 45,X and other variants. The phenotype of 45,X/46,X,+mar individuals varies by the genetic continent and degree of the mosaicism. The gene content of the marker chromosome is the most important when correlating the phenotype with the genotype. Here we present an 11-year-old female who was referred for evaluation of her short stature and learning disabilities. Conventional cytogenetic investigation showed a mosaic 45,X/46,X,+mar karyotype. Fluorescence in situ hybridization showed that the marker chromosome originated from the X chromosome within the androgen receptor (AR) and X-inactive specific transcript (XIST) genes. Therefore, it is possible that aberrant activation of the marker chromosome, compromising the AR and XIST genes, may modify the Turner syndrome phenotype.

Full Text Available In the Festschrift zum 70. Geburtstag von Anthony R. Birley, Richard Talbert published an article about a map which, as the author affirms, skipped the attention of the historians. In fact, it is a set of nine maps, at a scale of approximately 1:3,400,000, illustrating, according to a modern representation, the Roman world. The geographical space represented starts from the Antonine Wall and Britain in the left side and ends to Hierasycaminos on the border between Egypt and Nubia. The maps are part of a two volume project, commissioned by Agricol Fortia d’Urban (1756-1843. The book, entitled Recueil des Itinéraires Anciens comprenant l’Itinéraire d’Antonin, la Table de Peutinger et un choix des périples grecs, avec dix cartes dressées par M. le Colonel Lapie, was published in 1845 by the Imprimerie Royale, Paris. The maps were created by one of the most famous French cartographer of the XIXth century, Pierre M. Lapie (1799-1850. Our study discusses the information from this maps regading Moesia and the accuracy of the cartographer during the process of mapping the Roman roads from the south-danubian province.

Partial genome segments of a begomovirus were previously amplified from Wissadula amplissima exhibiting yellow-mosaic and leaf-curl symptoms in the parish of St. Thomas, Jamaica and this isolate assigned to a tentative begomovirus species, Wissadula golden mosaic St. Thomas virus. To clone the complete genome of this isolate of Wissadula golden mosaic St. Thomas virus, abutting primers were designed to PCR amplify its full-length DNA-A and DNA-B components. Sequence analysis of the complete begomovirus genome obtained, confirmed that it belongs to a distinct begomovirus species and this isolate was named Wissadula golden mosaic St. Thomas virus-[Jamaica:Albion:2005] (WGMSTV-[JM:Alb:05]). The genome of WGMSTV-[JM:Alb:05] is organized similar to that of other bipartite Western Hemisphere begomoviruses. Phylogenetic analyses placed the genome components of WGMSTV-[JM:Alb:05] in the Abutilon mosaic virus clade and showed that the DNA-A component is most closely related to four begomovirus species from Cuba, Tobacco leaf curl Cuba virus, Tobacco leaf rugose virus, Tobacco mottle leaf curl virus, and Tomato yellow distortion leaf virus. The putative Rep-binding-site motif in the common region of WGMSTV-[JM:Alb:05] was observed to be identical to that of Chino del tomate virus-Tomato [Mexico:Sinaloa:1983], Sida yellow mosaic Yucatan virus-[Mexico:Yucatan:2005], and Tomato leaf curl Sinaloa virus-[Nicaragua:Santa Lucia], suggesting that WGMSTV-[JM:Alb:05] is capable of forming viable pseudo-recombinants with these begomoviruses, but not with other members of the Abutilon mosaic virus clade. Biolistic inoculation of test plant species with partial dimers of the WGMSTV-[JM:Alb:05] DNA-A and DNA-B components showed that the virus was infectious to Nicotiana benthamiana and W. amplissima and the cultivated species Phaseolus vulgaris (kidney bean) and Lycopersicon esculentum (tomato). Infected W. amplissima plants developed symptoms similar to symptoms observed under field

Spondyloepiphseal dysplasia congenita in siblings born to unaffected parents: ? germ line mosaicism

Germ line mosaicism has been used to explain the birth of more than one child affected with a dominantly inherited disorder born to unaffected parents. Furthermore, it has been confirmed clinically in families where recurrence in siblings was originally thought to be autosomal recessive, but were affected individuals have reproduced affected offspring. Firm evidence of germ line mosaicism using mutation analysis by molecular methods exists for some autosomal disorders. We present two siblings with spondyloepipheseal dysplasia congenita (SEDC) born to unaffected parents. This suggests the presence of germ line mosaicism in this entity. Patient 1 was born at 32 weeks gestation to a G1P1 Puerto Rican mother. The pregnancy was complicated by polyhydramnios. The neonate, a short-limbed dwarf, died at 15 hours of age from respiratory distress and a compromised thoracic cavity. Patient 2, the sibling of patient 1 was born at 37 weeks gestation after a pregnancy complicated by polyhydramnios and prenatal ultrasound diagnosis of short-limbed dwarfism. The diagnosis of SEDC was made and, after review of the sibling`s postmortem X-rays, it was felt that she was similarly affected. The family history reveals no history of dwarfism or consanguinity. The SEDC is described as an autosomal dominant form of dwarfism with variable presentation including some cases that have been lethal in the neonatal period. SEDC is now believed to represent a family of collagen II mutations. Sporadic cases that have arisen in families with no history have been ascribed to new heterozygous mutations. Other families in which SEDC and SEMD recurred without a family history most likely represent germ line mosaicism. In these cases molecular studies should be pursued to document a collagen II mutation. We believe that germ line mosaicism is the most plausible explanation for recurrence in our family.

Image mosaicking is the process of piecing together multiple video frames or still images from a moving camera to form a wide-area or panoramic view of the scene being imaged. Mosaics have widespread applications in many areas such as security surveillance, remote sensing, geographical exploration, agricultural field surveillance, virtual reality, digital video, and medical image analysis, among others. When mosaicking a large number of still images or video frames, the quality of the resulting mosaic is compromised by projective distortion. That is, during the mosaicking process, the image frames that are transformed and pasted to the mosaic become significantly scaled down and appear out of proportion with respect to the mosaic. As more frames continue to be transformed, important target information in the frames can be lost since the transformed frames become too small, which eventually leads to the inability to continue further. Some projective distortion correction techniques make use of prior information such as GPS information embedded within the image, or camera internal and external parameters. Alternatively, this paper proposes a new algorithm to reduce the projective distortion without using any prior information whatsoever. Based on the analysis of the projective distortion, we approximate the projective matrix that describes the transformation between image frames using an affine model. Using singular value decomposition, we can deduce the affine model scaling factor that is usually very close to 1. By resetting the image scale of the affine model to 1, the transformed image size remains unchanged. Even though the proposed correction introduces some error in the image matching, this error is typically acceptable and more importantly, the final mosaic preserves the original image size after transformation. We demonstrate the effectiveness of this new correction algorithm on two real-world unmanned air vehicle (UAV) sequences. The proposed method is

Diagnostics based on X-ray computed tomography (CT) are becoming increasingly important, not only in the medical field but in industry and cultural heritage. CT devices typical for medical applications, however, can seldom be used on art objects because both they are not easily transportable and they often present high X-ray absorption. It is therefore necessary to make use of portable instrumentation and/or to develop tomographic systems optimized to the characteristics of the objects under examination. This work describes the computed tomography of a first century A.D. Roman bronze statue of Cupid (96.AB.53) in the collection of the J. Paul Getty Museum, within the collaborative framework between the Getty Conservation Institute and the Department of Physics and Astronomy (DIFA) of the University of Bologna (Italy). The tomography performed at the Getty facilities employed a 450 kV X-ray tube and a detection system developed at DIFA. The study highlighted the casting and construction techniques used by Roman foundry workers and provided information on the status of conservation of the statue. A 3D virtual reconstruction allowed the user to define different cross-sections enabling the study of the internal features.

During a survey in June 2011, severe leaf yellow mosaic disease was observed on about 45 % plants of Jatropha curcas growing in the Katerniaghat wildlife sanctuary in India. An association of a begomovirus with disease was detected in 15 out of 20 samples by PCR using begomovirus genus-specific primers and total DNA isolated from symptomatic leaf samples. For identification of the begomovirus, the complete genome was amplified using a Phi-29 DNA-polymerase-based rolling-circle amplification kit and total DNA from five representative samples and then digested with BamHI. The linearized RCA products were cloned and sequenced. Their GenBank accession numbers are JN698954 (SKRK1) and JN135236 (SKRK2). The sequences of the two begomovirus isolates were 97 % identical to each other and no more than 86 % to those of jatropha mosaic India virus (JMIV, HM230683) and other begomoviruses reported worldwide. In phylogenetic analysis, SKRK1 and SKRK2 clustered together and showed distant relationships to jatropha mosaic India virus, Jatropha curcas mosaic virus, Indian cassava mosaic virus, Sri Lankan cassava mosaic virus and other begomoviruses. Based on 86 % sequence identities and distant phylogenetic relationships to JMIV and other begomoviruses and the begomovirus species demarcation criteria of the ICTV (curcas were identified as members of a new begomovirus species and provisionally designated as jatropha leaf yellow mosaic Katerniaghat virus (JLYMKV). Agroinfectious clones of the DNA molecule of the begomovirus isolate were also generated, and the fulfillment of Koch's postulates was demonstrated in J. curcas plants.
