LONG TEMPORAL VARIATION OF SEISMIC PARAMETERS FOR SEISMIC PATTERNS IDENTIFICATION IN GREECE
Authors: Baskoutas I. , Panopoulou G. , Papadopoulos G.
Published: July 2018

A new approach of detailed spatio-temporal variation analysis of seismic data is proposed by means of FastBEE (Fast estimation of Big Expected Earthquake) aiming at the regional monitoring of seismic activity for premonitory seismic patterns identification. For the investigation of temporal variation, a set of seismic parameters is used, like the logarithm of the number of earthquakes logN, estimates of 6-value obtained by the maximum likelihood estimation model, time clustering of seismic activity AR(t) and of energy released EM, since they can be considered as precursory seismological indicators. Earthquake catalog data, used in this approach, were elaborated in order to construct the time series for each parameter within a time window, large enough, as to guarantee statistical meaningful result. The Hellenic trench-arc region under investigation is chosen in the basis of its seismotectonic characteristics, in relation to the spatial extent of the seismogenic zone. The tools were tested, for long temporal variation features in the Ionian Islands Sea and the North Aegean Sea regions and its successful applicability is presented. The rise of irregularity, along these temporal profiles, was formulated in specific quantitative premonitory seismic pattern. In most of the cases, FastBEE premonitory pattern found shows significant changes from the background values of each parameter. Parameter logN shows a valley form curve, which start to increase before the expected earthquake occurrence, as well as the energy parameter E273, while b-value temporal estimates are forming a mountain shape curve, before the occurrence of a big earthquake. Instead, parameter ÙR(t) present a rapid fluctuation, without any kind of premonitory character

Coda decay rates of 538 vertical components corresponding to local earthquakes which occurred in Greece during the period 1998 to 1999 were used to deduce the coda quality factor (Qc) characteristics in the Hellenic area. The seismograms have been selected from a broader sample of 776 records obtained at 8 stations of the National Seismographic Network operated by the Institute of Geodynamics of the National Observatory of Athens. Earthquake magnitudes range from 2.5 to 4.0; epicentral distances and depths are smaller than 100 km and 40 km, respectively. Using the Single Back Scattering model, the dependence of Qc on frequencies between 1 and 10 Hz has been investigated at each station and the usual Qc =Qo f relationships have been deduced. The spatial distribution of Qo has been drawn using waves that sample approximately equivalent ellipsoidal volumes with semiminor axis up to 100 km. The corresponding map shows a decreasing trend in SN direction.
APPLICATION OF 3-D VELOCITY MODELS AND RAY TRACING IN DOUBLE DIFFERENCE EARTHQUAKE LOCATION ALGORITHMS: APPLICATION TO THE MYGDONIA BASIN (NORTHERN GREECE)
Authors: Galanis O. C. , Papazachos C. B. , Hatzidimitriou P. M. , Scordilis E. M.
Published: July 2018

In the past years there has been a growing demand for precise earthquake locations for seismotectonic and seismic hazard studies. Recently this has become possible because of the development of sophisticated location algorithms, as well as hardware resources. This is expected to lead to a better insight of seismicity in the near future. A well-known technique, which has been recently used for relocating earthquake data sets is the double difference algorithm. In its original implementation it makes use of a one-dimensional ray tracing routine to calculate seismic wave travel times. We have modified the implementation of the algorithm by incorporating a three-dimensional velocity model and ray tracing in order to relocate a set of earthquakes in the area of the Mygdonia Basin (Northern Greece). This area is covered by a permanent regional network and occasionally by temporary local networks. The velocity structure is very well known, as the Mygdonia Basin has been used as an international test site for seismological studies since 1993, which makes it an appropriate location for evaluating earthquake location algorithms, with the quality of the results depending only on the quality of the data and the algorithm itself. The new earthquake locations reveal details of the area's seismotectonic structure, which are blurred, if not misleading, when resolved by standard (routine) location algorithms.

Published: July 2018

This paper deals with the printed educational material, created to accompany as study guide the videotape: " our geological heritage- Itinerary to geotopes of Macedonia and Thrace, in Northern Greece", IGME 1997 production. This printed document aims on the one hand, to support the videotape in order that the later, becomes interactive and flexible, while on the other gives the opportunity to candidate student of this independent educational cycle to be trained without the physical presence of educator. It is addressed to distance learning students of geosciences or environment or in persons interested in geology and geological heritage, as well as teachers dealing with environmental education, in tourist guides, land use planners etc. There is no ambition to prepare specialists in geology with this. It simply aims to help in understanding that rocks and subsoil are integral part of the natural world and contain significant information for the past of the Earth, our past. It also aims to help in understanding some meanings of geoconservation, the relevant new terminology of this concept, and to create a communication code with the specialists in order to facilitate the cooperation. The videotape, half an hour duration, aims to give the necessary images and script.
THE DEPOSITIONAL PALAEOENVIRONMENT OF LIGNITE OF BOREHOLE #53 IN THE NEOGENE ALMYROS BASIN, CENTRAL GREECE
Authors: Μπουζίνος Α. , Ιωακείμ Χρ.
Published: July 2018

The aim of the present study is to reconstruct the depositional palaeoenvironment of the Almyros lignite seam cored at site #53, in Almyros Basin, Central Greece. Based on palynological and coal-petrographic data we obtained information concerning the coal-depositional environment, as well as the palaeoclimatic conditions in the surrounding area. At the above site, a peatland was developed in Upper Miocene - Lower Pliocene under limnotelmatic conditions. The climate was relatively wet and warm. Angiosperm herbaceous vegetation dominated in the fen, while Gymnosperms were sparse. The high content of detrohuminite suggests that peat was formed under reducing conditions, which favoured bacterial activity and humification of the organic matter.
GENESIS AND PHYSICAL CHARACTERISTICS OF THE NEOGENE RED BEDS FROM THE CEDARHILS OF THESSALONIKI, MACEDONIA , GREECE
Authors: Tsirambides A.
Published: July 2018

The genesis and the physical characteristics of the Neogene red beds of the cedar hills surrounding Thessaloniki are studied in this paper. The peri-urban forest, which covers these hills, has a 3,022 ha area. The topographic relief is smooth and is divided in eight small drainage basins, tapped through small creeks. The elevation of the surrounding hills varies between 85 and 560 m. The dominant land slopes vary between 20 and 55%. All the samples are coarse grained, poorly sorted and friable and present earthy lustre and red colour because of the extensive presence of iron oxides. Angular to sub-angular rock fragments derived from the metamorphic bedrock are very common. Petrographically, the studied red beds belong to the clayey sands. The extended presence (41-66%) of coarse silt and sand size grains (>20 pm) in the samples suggests a mild intensity of in situ weathering of the bedrock. X-ray diffraction analysis of the coarsest fractions 250-20 pm and 20-2 μιτι revealed in decreasing abundance the presence of quartz, feldspars, epidote, micas, chlorite, pyroxenes, amphiboles, and talc. These fractions contain the 2M polytype of mica, while in the fraction <2 pm the 1Μα polytype of illite predominates. In the clay fraction (<2 pm) illite, smectite, and chlorite predominate. The presence of mixed-layer minerals is limited, testifying the almost complete character of hydrolysis of the primary minerals. The formation of red beds took place on low relief land under alternating wet and dry seasons, which prevail in the eastern Mediterranean region since Neogene. The clay minerals are the in situ weathering products of the primary minerals of the greenschists, gneisses and gabbros predominating in the studied area. The extensive presence of clay size grains (11-26%) in the samples, their poor sorting, and their sub-angular morphology, indicate that the red beds are texturally immature. In addition, the abundance of feldspars and Fe-Mg minerals reflects mineralogical immaturity. The low relief and the long-lasting tectonic stability in the Thessaloniki district were essential for the significant thickness of the red beds. The oxygen isotope data of the <0.2 pm fraction (+18.2 to +18.8%o) confirm the pedogenic origin of the clay minerals present. The red beds studied present low plasticity with liquid limit (WÏ) 26.9 to 33.4% and plasticity index (lp) 9.1 to 17.3%. In addition, they have high consolidation index (lc) values (1.03 to 2.28). The swelling potential is low to medium and the activity varies between 0.5 and 1.0. The consolidation and induration degree of the samples analyzed is low, because of the great range of their mineralogical composition and the mild conditions of pressure and temperature to which they have been submitted. The studied red beds are not considered problematic for the foundation of various constructions on them.
THE OCCURRENCE OF THE METAXYTHERIUM CUVIERI CHRISTOL IN THE LATE MIOCENE SEDIMENTS OF SITIA, CRETE
Authors: Μαρκοπούλου-Διακαντώνη Α. , Λόγος Ε.
Published: July 2018

Two Sirenian skulls with their upper jaws coming from the Upper Miocene area of the village Achladia determined as Metaxytherium cuvieri Christol have been studied. This species is known up today from the M. Miocene of France (Cottreau, 1928). One skull of Metaxytherium cuvieri Chritol is found at the locality «Tympana» of Achladia village, within the formation of marls- gray marls, at an height of 170 m ca., while the second one is found in the locality «Kefala» of Achladia village within the formation of the gray marls at an altitude of 196 m c a . Metaxytherium cuvieri Christol is an intermediate type between Dugongs and Recent Lamantins (=Manatees). The occurrence of Metaxytherium cuvieri Christol in the Hellenic area contributes to our knowledge of its geographical and stratigraphical distribution in this eastern region of the Mediterranean basin during the Upper Miocene
DIVERSITY AND ABUNDANCE TRENDS OF BENTHIC FORAMINIFERA FROM THE SOUTHERN PART OF THE IRAKLION BASIN, CENTRAL CRETE
Authors: Drinia H. , Antonarakou A. , Tsaparas N.
Published: July 2018

Benthic foraminiferai fossil assemblages of the Roufas Section, southern Iraklion Basin, central Crete, were analyzed for the first time. Taxonomic and quantitative analyses were made in order to obtain paleoenvironmental (physical as well biological) information. A data set has been subjected to R- and Q-mode cluster analyses in order to demonstrate the linkage between taxa distribution and paleoenvironmental gradients. Our results suggest that oxygenation and trophic conditions of the near-surface sediments are the most important factors that control the community structure of the benthic foraminiferai fauna. The application of the oxygen transfer function - based on the use of benthic foraminiferai taxa from oxyphilic habitats - to the benthic faunas of the Roufas Section, allows the reconstruction of the oxygen contents of the bottom waters. Apart from the middle part of the section, no severe disturbances are recorded, pointing to the fact that we are dealing with an overall rather well ventilated water column during most of the part of the sequence.
LOFTUSIA CF. ANATOLICA HORIZON IN UPPER MAASTRICHTIAN LIMESTONES OF THE EASTERN GREECE PLATFORM (MOUNT PTOON, BOEOTIA, GREECE): PALAEOBIOGEOGRAPHICAL REMARKS
Authors: Zambetakis - Lekkas A. , Kemeridou A.
Published: July 2018

Researches on upper Cretaceous limestones from the Eastern Greece platform in the area between Kokkinon and Akrefnion (Boeotia, Greece) revealed the presence of a horizon rich in Loftusia cf. anatolica (foraminifer). In this horizon, of late Maastrichtian age, L. cf. anatolica is associated with debris of Rudists, Orbitoides media, O. apiculata, O. gensacicus, Siderolites calcitrapoides, Omphalocyclus macroporus, Hellenocyclina beotica, Miliolidae, Dasycladaceae and echinoderms. It is found in an undisturbed sequence of limestones, where both the underlying and the overlying horizons are of the same facies and contain debris of Rudists, Hellenocyclina beotica, Orbitoides media, Siderolites calcitrapoides, Sulcoperculina sp., Rotaliidae, Mélobesiées,Nummofallotia sp., echinoderms. L. cf. anatolica is confined in the above mentioned horizon and it is found neither in the underlying nor in the overlying beds. This fades reflects an outer shelf environment in front of the rudist reefs. It is the first time that this species is reported in situ in Greece in an undisturbed stratigraphie sequence of upper Cretaceous limestones up to Paleocene flysch.

SHORT PERIOD CHANGE DETECTION OF SPERCHIOS LOWER DELTA AREA USING SPACE RADAR IMAGES
Authors: Psomiadis Em. , Migiros G. , Parcharidis Is. , Poulos S.
Published: July 2018

Being highly dynamic by nature, due to their changing hydrological regime and to the encroachment of urbanization, industrialization and changing patterns in agriculture, reliable and timely information of coastal areas is a prerequisite for their effective management. The aim of this paper is to assess the use of ERS-2 SAR satellite data to detect short period changes in the case of the R. Sperchios coastal area that is located at the eastern part of the Maliakos Gulf (near the middle of the east coast of the Greek mainland). A Landsat 7 (ΕΤΜ+) image served as a reference for the interpretation of the ERS images. In order to highlight and detect the changes occurred in the study area two methods were applied. The first method is based on the creation of a Temporal Differentiate Image, consisted of the three ERS-2 images (Figure 1). The second method concerns the implementation of Principal Component Transform (PCT) on the three multitemporal scenes. The final images derived from the two different methods were compared and evaluated. Both methods didn't show any significant change along the coastline. PCT method illustrates more clearly the seasonal changes of crops in the lower delta area. Eventually, radar technology gave the opportunity to discriminate shallow areas, which does not appear in satellite optical data. Concurrently, the effect of wind direction was investigated.

Palamari bay is loceted on the northeastern coast of Skyros island (Sporades islands, Aegean sea). The area is of fundamental archaeological interest because of a prehistoric archaeological site, located at the northern part of the bay. In order to investigate the geomorphic evolution of the broader area a detailed geomorphological mapping of the coastal and submarine area of the bay at a scale 1:5000 was carried out. Additionally the stratigraphy of the late Holocene sediments was studied and micropaleontological and palynological study of collected samples from the deposits of the coastal alluvial plain as well as radiocarbon dating of selected layers rich in organic material were done. The main morphological features of the coastal zone are two beachrock formations with the first one extending along the coastline reaching a depth of-1.70 m and the second one occupying the southern part of the bay lying between -1.90 and -2.90 m below sea level. Microfaunal and palynological analysis of collected samples identified two main sedimentary sequences. The uppermost sedimentary unit represents a terrestrial depositional environment dominated by aeolian wellsorted sands and fluvial sediments. The underlying sequence showed a lagoonal depositional environment, implying a protected lagoon connected to the sea, which was periodically supplied with fresh water. This lagoon existed between 3700 years BP and 700 years BP as radiocarbon dating showed. The existence of this lagoon after that period is possible.
STUDY OF THE DISTRIBUTION OF PRECIPITATION IN DISTRICT OF EASTERN MACEDONIA AND THRACE FOR THE PERIOD 1964 -1998
Authors: Πεταλάς Χ. , Πλιάκας Φ. , Διαμαντής Ι. , Καλλιώρας Α.
Published: July 2018

This paper refers to the distribution and the quantitative approach of the precipitation of the Region of Eastern Macedonia and Thrace for the period 1964 - 1998 and it is based on data from 64 meteorological stations. The distribution of the precipitation varies significantly according to each different location. The mountainous terrain plays a significant role on the distribution of precipitation while the low height of precipitation is easily observed within the coastal zone. The dense forested areas are characterized by high precipitation heights and flood events. The mean precipitation for the period 1964-1998 is 660 mm. The elaboration of the rainfall data shows a distinct reduction during 1964-1998 with a drought period between 1981 and 1993. December and November are found to be the most wet months, while it is observed that 70.2% of the precipitation occurs between October and March. It is estimated that 76% to 80% of the precipitation are lower than 10 mm. The percentage of annual precipitation which outflows and/or infiltrates ranges between 23.5% to 42.5%.
CURRENT ACTIVITY IN THE THERMAIKOS GULF CONTINENTAL MARGIN , IN RELAÏJON TO MODERN SEDIMENTATION PROCESSES
Authors: Poulos S. E. , Drakopoulos P. G.
Published: July 2018

The area under investigation represents the NW continental margin of the Aegean Sea i.e. the Thermaikos Gulf and the associated NW Sporades Basin. Surficial seabed sediments are of terrigenous origin whilst in terms of grain size, offshore sediments maybe distinguished into silty sediments that cover the northern and western part of the Gulf; clayey that cover the floor of the Sporades basin and relict sands that cover mainly the central and eastern part of the self. Current meter measurements from different water depths were obtained from 10 stations on the shelf, shelf/break, within canyons and in the Sporades Basin. Surface currents over the period of the investigation are dominated by inertial currents generated by wind events. Inertial period currents also dominate the near-bed currents on the continental shelf and in Sporades Basin. On the canyon slope, however, tidal currents are the dominant ones; these relate to the amplification of the internal tide, within the submarine canyon. Measured near-bed currents are below the threshold for sediment movement in the case of flat seabeds, although they are capable to inhibit deposition of the settling clayey particles. This contributes also to a further offshore dispersal of riverine sediments. Moreover, increased bed roughness due to benthic activity can cause resuspension for lower current speeds.

Visual-Graphic Design of a Unitary Constructive Model to Solve Analogues For Apollonius Problem Taking into Account Imaginary Geometric Images
Authors: Волошинов Д. , Voloshinov Denis
Published: July 2018

The Apollonius problem on construction of circles, tangent to three arbitrary given circles of a plane, is one of classical geometry’s well-studied problems. The presented paper’s materials are directed at development a unified theory for Apollonius problem solving, taking into account it’s not only real, but also invisible complex-valued images. In the paper it has been demonstrated, that fundamental geometric structures, on which Apollonius problem is based on, are applicable not only to real, but also to complex-valued data, that makes possible to eliminate many exceptions, currently existing in it. In this paper Apollonius problem’s fundamental nature and its strong correlation with projective and quadratic geometric transformations has been disclosed. It has been proved that Apollonius problem and its analogues have a single solution method, in contrast to the prevailing idea that these problems can be solved only by separate particular methods. A concept of geometric experiment proposed by the author has allowed find out many previously unknown and discussed in this paper common factors, due to the set of many computational tests in the system Simplex for visual design of geometric models. In this paper is considered an example for solving an analogue of Apollonian problem for three-dimensional space, but proposed algorithm’s operation is universal, and it can be equally applied to solving similar problems in spaces of arbitrary dimensions. Obtained results demonstrate capabilities of methods for constructive modeling and multidimensional descriptive geometry in application to solving of complex mathematical problems, and determine the trends in development for automation systems of constructive geometric modeling.

Published: July 2018

When studying the theory of contour construction in “Affine and Projective Geometry” course on educational program specializations “Computer-Aided Design Systems” and “Applied Informatics in Design” a unit of computational and graphic task "Contour Construction" is carrying out in structural design. In this computational and graphic task the contour constructions are carrying out by second-order curves (a circle — by the radius and graphical method; a hyperbola, an ellipse, a parabola — by means of Pascal curves, taking into account positions of engineering discriminant). The constructions of an arc of ellipse, hyperbola, and parabola are carried out based on Pascal theorem: in any hexagon, which vertices belong to a second-order series, three points of the opposite sides’ intersection lie on one straight line — the Pascal line. However, in construction of a conic (a second-order curve), it is necessary to draw students’ attention to the fact that the points belonging to a second-order series (a second-order curve, or a conic) make a geometrical locus of intersection of Pascal hexagon’s adjacent opposite sides. By this method students successfully construct conjugate arcs of an ellipse and a hyperbola with other conics. The construction of a parabola arc, conjugated with other conics, is carried out by the method of engineering discriminant (it is more convenient to divide line segments in halves: a median and a triangle side, which is opposite to its vertex lying on a parabola arc). It should be noted that theoretical and practical material on this subject corresponds to the assimilation of Study Plan’s necessary competences (in accordance with each educational program), however, some aspects of this subject are accepted by students simply by trust. The aim of this paper is research of construction methods for parabola, applied to contour simulation.
Igneous Rock Associations 22. Experimental Petrology: Methods, Examples, and Applications
Authors: Shaw Cliff S.J.
Published: July 2018

Experiments are an important source of basic information in petrology, from thermodynamic data used to develop predictive models to physical property data used to understand magma ascent and eruption. Since we all use experimental data in our work as geoscientists, it is important that we have a basic understanding of the methods used to prepare and perform experiments on rocks and minerals and their synthetic analogues. In this review I examine how the observational science of geology changed in the late 1800’s with the development of the interdisciplinary science of physical chemistry. The second part of the paper discusses what factors need to be considered in designing an experimental study; it focuses particularly on the problems of reaching equilibrium on the short timescales available in the laboratory. In the final section, I give four examples of geological problems that have been solved using experimental methods and make some suggestions about the directions that future experimental campaigns might take.RÉSUMÉL’expérimentation est une source importante d’information de base en pétrologie, qu’il s’agisse de données thermodynamiques pour développer des modèles prédictifs, ou des propriétés physiques utilisés pour comprendre la montée et l’éruption d’un magma.

Dans la présente étude, je me suis penché sur les changements survenus en science d’observation qu’est la géologie, à la fin des années 1800, avec le développement de la science interdisciplinaire de la chimie physique. La deuxième partie de l’article traite des facteurs à prendre en compte dans la conception d’une étude expérimentale; elle porte en particulier sur les problèmes d’atteinte d’un équilibre sur les temps courts du laboratoire. Dans la dernière section, je donne quatre exemples de problèmes géologiques qui ont été résolus à l’aide de méthodes expérimentales, et je fais des suggestions sur des orientations qui pourraient être adoptées lors de campagnes expérimentales à venir.

Inventory Control and Delivery Time Quotation for Assembly Supply Chains
Authors: Chen Shi , Moinzadeh Kamran
Published: July 2018

We study an inventory system involving a contractor, who provides quotations of delivery times to customers, and suppliers, who stock prefabricated modules that the contractor will use to complete orders. The customers’ decisions on whether to wait or leave depend on the quotations. This is an assembly system with partial lost sales, where the interaction between the quotation policy and the inventory policy is complicated. We consider either a uniform or an adaptive quotation policy and either an independent or a modified S policy to control the inventory. Under the independent S policy, we show that the multiple-supplier system can be converted into a one-supplier system, which enables us to devise an efficient simulation algorithm to identify the optimal parameters of this policy. Under the modified S policy, the suppliers can be rearranged into a serial system, but given the tedious computational nature of the modified S policy, we propose a dynamic programming–based heuristic, which is efficient and accurate, to identify the optimal parameters of this policy. Finally, we consider the decentralized setting, for which we propose a coordination mechanism that requires the contractor to impose a penalty for the suppliers’ stockouts and to provide a subsidy for the suppliers’ inventory.

Public Warnings in Counterterrorism Operations: Managing the “Cry-Wolf” Effect When Facing a Strategic Adversary
Authors: Bakshi Nitin , Pinker Edieal
Published: July 2018

Public warnings have the potential to mitigate the threat from terrorism: the public is alerted, and in response, the terrorist may defer his attack. Paradoxically, warnings can be a victim of their own success. The absence of an attack may be misconstrued by the warning recipients as a false alarm, leading to warning fatigue and a dampened response to future warnings—also referred to as the “cry-wolf” effect. To capture this phenomenon and examine its implications, we model the interaction between the defender and the terrorist using a dynamic game-theoretic framework. Our equilibrium results suggest that absent any political gamesmanship or incompetence, the prospect of false alarms can lead to either lengthy stretches of sustained warning, or more attacks at lower warning levels. Furthermore, we recommend that warnings and security deployment ought to be decoupled and treated as independent levers. By studying how the equilibrium shifts with changes to the parameter regime, we find that an increase in the terrorist’s “readiness” can result in a lower frequency of terrorist attacks; and a rise in the cost of issuing warnings can induce more frequent warnings.

Resumo: Recorrendo a um conjunto documental inédito presente na Biblioteca do Rio de Janeiro, este artigo pretende estudar a evolução da Casa dos Barretos da Quarteira nos séculos XV e XVI. Partindo das origens da linhagem e da Casa em Portugal, o artigo aborda a estratégia de consolidação patrimonial e de engrandecimento da Casa ao longo do século XV, procurando percepcionar as bases exactas do poder alcançado no século XVI. Esta análise permite compreender como os Barretos da Quarteira evoluíram de uma nobreza de serviço provincial algarvia a uma nobreza de serviço cortesã que foi crescentemente acumulando cargos no Império (Marrocos, Índia e Brasil) durante o século XVI. Neste contexto, procura-se debater as condições que tornaram viável a titulação de uma não titular da Casa, D. Francisca de Aragão, em 1599, como 1º condessa de Ficalho, como corolário de uma estratégia prosseguida anteriormente e que tinha como fito a titulação da Casa.Abstract: Departing from an unpublished documental series found at the Library of Rio de Janeiro, this article intends to study the evolution of the House of the Barretos of Quarteira in the XV and XVI centuries. Starting from the origins of the lineage in Portugal, the article approaches the patrimonial and ennoblement strategies of this House in the XV century in order to fully understand the exact basis of its power in the XVI century. This analysis enables to understand how the Barretos of Quarteira evolved from a provincial nobility from Algarve to a courtesan nobility that accumulated relevant offices in the Portuguese Empire (Morocco, India and Brazil) during the XVI century. This article also attempts to debate the conditions in which the entitlement of a non-titular of the House, D. Francisca de Aragão, as 1ª countess of Ficalho, in 1599, occurred as the consequence of a strategy perceived previously in order to achieve a title for the House.

Biologics and biosimilars in inflammatory bowel disease
Authors: Murphy Judith Anne
Published: July 2018

Although there is no cure for inflammatory bowel disease (IBD), its symptoms can be treated and remission induced using biological medicines, including the anti-TNF (tumour necrosis factor) drug infliximab. Biosimilars of infliximab have been made available in guidelines from the British Society of Gastroenterology and the National Institute for Health and Care Excellence, and they represent a considerable cost-saving opportunity for the NHS. The potential difficulties of switching infliximab to a biosimilar at a hospital can be overcome with a two-step implementation process. Emerging evidence on the factors influencing the variable effectiveness of these therapies is shaping best clinical practice, including studies on anti-TNF trough levels and anti-drug antibodies to infliximab, as well as the use of immunosuppressants. IBD nurse have the specialist knowledge and are in a unique position to measure progress, educate patients and encourage compliance, all of which helps optimise and prolong the effectiveness of biologic treatment.

Prescribing options for ulcerative colitis
Authors: Wakefield Benjamin , Stansfield Cath
Published: July 2018

Ulcerative colitis causes periodic, debilitating inflammation of the colon. Prescribers can induce and maintain remission of disease activity with a variety of drugs, including aminosalicylates (mesalazine), corticosteroids (prednisolone, hydrocortisone, budesonide) and immunosuppressants (thiopurines, methotrexate, ciclosporin). These have more recently been joined by biologics, including TNF antagonists (infliximab, adalimumab, golimumab) and adhesion molecule antagonists (vedolizumab). Guidelines are available to help prescribers match each patient to the most clinically effective and cost-efficient therapy.
Improving Academic Conferences – Criticism and Suggestions Utilizing Natural Language Processing
Authors: Eckhaus Eyal , Davidovitch Nitza
Published: July 2018

This study focuses on the evaluation of academic conferences and ways of improving them. The study includes a case study of one university in Israel. Sixty two academic faculty members from varied departments completed a questionnaire, including 61.7% women and 38.3% men. The research participants were asked a single open question: "What do you think could be improved at conferences?" In addition, age, seniority, and the number of times the respondents had initiated or served as a partner in initiating a conference were also examined. The main findings are as follows: Age predicts seniority. Seniority has a positive effect on the number of times the respondent organized or was a partner in organizing a conference. Seniority has a negative effect on time, i.e., the more senior the faculty member the more he or she would like conferences to be short and to the point. Moreover, the amount of initiatives to organize a conference or to be a partner in establishing a conference has a negative effect on interaction, i.e., the more initiating the faculty member the less he or she is interested in interpersonal interactions at conferences. The wish to space out sessions and lectures has a positive effect on the need to improve the quality of the lectures.

One of the central aspects of displacement and migration is resilience on behalf of the affected individuals. UNHCR reports that the number of displaced people around the world reached 65 million by the end of 2015. In another report UNHCR states that the number of Syrian refugees in Iraq is 233,224. While IOM reports that the number of the internally displaced persons in Iraq between 2014 and 2016 reached to 3.4 million. As it is crucial to communication and, thus, survival, language is vital to promoting resilience of such people. Nowadays, English language learning provides numerous opportunities for individuals to succeed; hence, it is essential in building resilience among displaced populations. The current study aimed to explore resilience level of the displaced adolescents in Iraq, also to verify the impact of English language learning on their lives. The study has been conducted in camp and non-camp schools via the delivery of a CD-RISC-25 questionnaire as quantitative method, followed by interviews as qualitative method. The results concluded that the participants had medium resilience level, and learning English plays different roles in building resilience of the participants.
