Published: May 2020

Introdução: A fibromialgia é uma síndrome reumática de etiologia desconhecida, que acomete predominantemente mulheres, caracterizada por dor musculoesquelética difusa e crônica, sítios anatômicos específicos dolorosos à palpação (tender points). A fisioterapia tem sido indicada no tratamento da FM, pois possibilita a análise e a intervenção na mobilidade humana, reintegrando o paciente ao meio onde vive e, promovendo assim, uma melhora na qualidade de vida. Objetivo: Revisar os estudos da literatura, a fim de verificar a eficácia das técnicas de cinesioterapia no tratamento de FM e ampliar as perspectivas sobre a terapêutica dessa patologia. Metodologia: Foram pesquisados estudos publicados entre os anos de 2002 a 2016, em português, na Biblioteca Virtual da Associação Evangélica de Ceres e nas bases de dados eletrônicos Scielo (Scientific Electronic Library Online), Pubmed (United States National Library of Medicine) e Google Acadêmico. Resultados e discussão: Em relação aos exercícios de alongamento muscular, observou-se uma melhora significativa no sono e uma diminuição da rigidez, tendo o alongamento estático, técnica mais comum e segura proporcionado aumento da flexibilidade, ganho de condicionamento físico, diminuição da dor e da fadiga muscular. Exercícios aeróbios por sua vez, trazem benefícios físicos como a diminuição da tensão muscular, disfunção física e dor. Conclusão: O exercício aeróbio tem ganhos mais diversificados do que os exercícios de alongamento. Portanto, se ambas forem executadas juntas ou simultaneamente, podem trazer mais resultados em menor tempo e com maior rendimento.
Networked Economic Value Creation in Event Tourism: An Exploratory Study of Towns and Smaller Cities in the UK
Authors: Norman Mark , Nyarko Nana
Published: May 2020

This study explores the role of networks in generating economic value for event tourism in towns and smaller cities in the UK. Although networks have been shown to create a wide range of value, research in this context is limited and little is understood of if or how economic value
is generated. The lens used in this study was the value creating side of the business model canvas with local government organizations as the focal node examining the flow of economic value from partners, activities, and resources. There were survey responses from 112 different town and city
organizations across the UK. The study found that only the "activities" element of the network contributed significantly to creating economic value in an event tourism context. The network components of "partners" and "resources" were not on their own significant to the creation of economic
value. The outcomes of this article suggest that practitioners in towns and cities should strategize their engagement with local networks through a formal event tourism strategy that clearly defines how they operationalize engagement activities within that network in order to facilitate economic
value creation. In addition, the article raises questions around what resources are needed at the focal node (local government organizations) in order to maximize the economic value created by the network.
The Role of Risk Factors (Onset - Hospitalization, Onset - Surgery, Increase in Pulse, Systolic Blood Pressure) on Death in Gastric Perforation
Authors: Lubis Faisal Amri , Singh Sarup
Published: May 2020

ABSTRACT

Introduction. Gastric perforation is the second most common complication due to peptic ulcer after bleeding where the risk of mortality in patients who have received surgical treatment is still high. The factors that have the greatest influence on the death of the patient are old age and the time span of handling more than 24 hours. This study aims to determine the relationship between risk factors (onset - hospitalization, onset - surgery, increased pulse, decreased systolic blood pressure) on the death of gastric perforation patients undergoing surgery at Dr. General Hospital Mohammad Hoesin Palembang.

Methods: An observational analytic study with a case-control study design was carried out from August to October 2017 at the Dr. General Central Hospital Mohammad Hoesin (RSMH) Palembang. There were 90 respondents consisting of 30 sample groups with death cases and 60 sample groups with life control. The relationship between independent and dependent variables was analyzed by Chi Square test while risk factors that play a role in death in gastric perforation patients who performed surgery were analyzed with the Logistic Regression test. Data analysis uses SPSS version 18.0.

Results. There was a significant relationship between increased pulse (OR = 11,227 CI95% 3,923-32,129; p = 0,000), onset - MRS (hospital admission) (OR = 4,125 CI95% 1,579-10,773; p = 0,006) and onset - surgery (OR = 3,786 CI95% 1,267-11,308; p = 0.029) on the death of a gastric perforation patient undergoing surgery. With the Logistic Regression test, an increase in pulse and onset - hospital admission was significantly related to the death of a gastric perforation patient undergoing surgery.

Conclusion. It can be concluded that the increase in pulse and onset of hospital admission are risk factors that contribute to the death of gastric perforation patients who undergo surgery.

PROCEDURE FOR EVALUATION OF THE APPLICATION’S EFFICIENCY OF THE PARACHUTE SYSTEMS FOR THE AIR DROPPING
Authors: Dmytriiev V.
Published: May 2020

The article proposes a procedure for evaluation of the application’s efficiency (AE) of parachute systems (PS) for the air dropping (AD). Based on the analogy with the index of combat effectiveness of armament and military equipment, the AE of PS can be evaluated by using the typical mission performance probability of AD - personnel or cargo positioning to site, while maintaining their combat capability to accomplish a mission of the parachute assault force.

In this formulation, the process of accomplishing the typical mission of AD consists of the following stages: delivery of cargo to the airborne objective area, the exit of the aircraft to the computed air release point, the actual air dropping. Further analysis showed that the most influential factors affecting successful accomplishment of the typical mission of AD by the stages are: the reliability of the aircraft, the ability to overcome the enemy air defense without consequences for the accomplishment of AD, the property retention of PS while in flight considering flying conditions of the aircraft to the area of ​​the AD, problem solving of determining of the computed air release point under the actual conditions, the accuracy of the aircraft's exit to the computed air release point, the reliability of the PS, the covertness of the AD, the accuracy of cargo’s landing to the size-defined site, speed of the cargo’s landing. For each of the factors, the calculating formulas were defined in the article in the form of the probability of a positive influence on the successful accomplishment of the mission of the AD. The product of all these probabilities is evaluation of the AE of PS.

For example, the calculations of the AE of PS DPS and Status-CH types in equal conditions of AD and Status-CH by using various tactical techniques of AD were made. The results of the calculations are completely consistent with the logical considerations and practice of the PS application, which testifies to the adequacy of the proposed procedure and the feasibility of its application.
THE BEHAVIOURAL CONSEQUENCES OF PERCEIVED SERVICE QUALITY: A STUDY OF THE INDIAN TELECOMMUNICATION INDUSTRY
Authors: Jhamb Deepika , Mittal Amit , Sharma Pankaj
Published: May 2020

The telecom industry in India has witnessed substantial growth over the last decade.
Rapid growth of telecommunications is opening up the doors for many telecom players from Europe, Asia and
other parts of the world, resulting in increased competition and tariff reductions. In the present competitive
environment, the services perceived by the customers and their behavioural intentions play a pivotal role
in the customer switching process among service providers. With the changing expectations of service quality,
it becomes imperative to discover the gap between customer expectations and customer perception. In this context,
the aim of the present study is to identify the existing gap between customer expectations and perceptions
and investigate the relationship between post-experience perception of service quality and customers’
behavioural intentions. The data was collected from 500 customers in Delhi NCR, India. Paired sample t-test
and multiple correlation analysis were performed. The results of the study points out the key areas wherein
the service gaps are considerably high such as reliability and responsiveness. The customer behavioural
intentions, such as “Complain to customer service if a problem occurs”, “Switch to another service provider”
and “Reducing the usage with a particular service provider”, have shown a strong relationship with quality
of service. The findings of the study confirm that the perceptions of customers regarding the quality of
service received definitely have an impact on their behaviour.

Published: May 2020

Hydatid disease is one of the most common parasitic diseases caused by Echinococcus granulosus worm. In this disease, involvement of all organs is likely. However, primary hydatid cysts of muscle tissue are so rare that occasionally in differential diagnosis, cystic masses are not placed in endemic areas. Timely and accurate diagnosis is crucial to prevent unnecessary biopsy. In this case-series study conducted in hospitals of Semnan and Tehran, Iran, from 2009 to 2014, 15 patients with musculoskeletal problems due to hydatid cyst were evaluated. In each case, information about the patientâ€™s clinical manifestations, including initial complaint, cyst location, treatment method, location of involvement organ, duration, dose of drug used and diagnostic method was evaluated. According to results of the present study, the prevalence of musculoskeletal system involvement was 7.21%. The most common site of involvement was spine and paravertebral muscles (7 cases) and the most common symptom was compressive symptoms on the spinal canal. Magnetic resonance imaging was the most commonly used diagnostic method and only in 1 case a wrong pre-operative diagnosis was made. Eleven patients reported a history of recurrence at the site of previous surgery (3 cases of hip involvement and 6 cases of spine involvement). There were 5 cases of recurrence following recent treatment, 2 of which were hip involvement and 2 cases of spine involvement. Furthermore, most patients (12 cases) underwent cyst resection surgery. The results of this study showed that although hydatid cystic skeletal muscle is rare, due to the possibility of repeated recurrence, especially in cases of spine and bone involvement, endemic areas should be considered in the differential diagnosis of each cystic mass of muscle and bone.
Conceptual Model and Design of Semantic Trajectory Data Warehouse
Authors: Kwakye Michael Mireku
Published: May 2020

The trajectory patterns of a moving object in a spatio-temporal domain offers varied information in terms of the management of the data generated from the movement. The query results of trajectory objects from the data warehouse are usually not enough to answer certain trend behaviours and meaningful inferences without the associated semantic information of the trajectory object or the geospatial environment within a specified purpose or context. This article formulates and designs a generic ontology modelling framework that serves as the background model platform for the design of a semantic data warehouse for trajectories. The methodology underpins on higher granularity of data as a result of pre-processed and extract-transformed-load (ETL) data so as to offer efficient semantic inference to the underlying trajectory data. Moreover, the modelling approach outlines the thematic dimensions that offer a design platform for predictive trend analysis and knowledge discovery in the trajectory dynamics and data processing for moving objects.

Published: May 2020

Building information modeling (BIM) is a revolutionary technology that provides all the necessary mechanisms to achieve end-to-end communication, data exchange and information sharing between project actors, leading to smarter outcomes for communities and more efficient projects for AEC service providers. 3D models generated in the context of engaging in the BIM process and as-delivered physical assets through building management systems (BMS) adopt Internet of Things (IoT) architectures and services. However, the orchestration of IoT devices in a highly modular environment with many moving parts and inter-dependencies between the stakeholders of this environment, lead to many security issues. This article focuses on applying novel technologies in the construction industry, such as BIM, IoT, and Blockchain, but also on examining their interconnection and interoperability on a proposed system architecture on a case of a building (museum), where efficient security, management and monitoring are considered crucial factors for the unobstructed operation of the organization that hosts.
A Novel Trust Model for Secure Group Communication in Distributed Computing
Authors: Ramu Naresh , Pandi Vijayakumar , Lazarus Jegatha Deborah , Radhakrishnan Sivakumar
Published: May 2020

Distributed networks are networks in which each node can act as a server or client and hence any node can provide service to any other node. In such a scenario, establishing a trust model between the service providing user and the service utilizing user is a challenging task. At present, only a few approaches are available in the past literature to provide this facility. Moreover, the existing approaches do not provide high trust accuracy. Therefore,a novel efficient trust model has been proposed in this article to support the secure dynamic group communication in distributed networks. The main advantage of the proposed work is that it provides higher trust accuracy. Moreover, the proposed work takes less memory for maintaining the trust values and increases the packet delivery ratio in comparison with other existing works which are in the literature.

Published: May 2020

Mobile botnets are gaining popularity with the expressive demand of smartphone technologies. Similarly, the majority of mobile botnets are built on a popular open source OS, e.g., Android. A mobile botnet is a network of interconnected smartphone devices intended to expand malicious activities, for example; spam generation, remote access, information theft, etc., on a wide scale. To avoid this growing hazard, various approaches are proposed to detect, highlight and mark mobile malware applications using either static or dynamic analysis. However, few approaches in the literature are discussing mobile botnet in particular. In this article, the authors have proposed a hybrid analysis framework combining static and dynamic analysis as a proof of concept, to highlight and confirm botnet phenomena in Android-based mobile applications. The validation results affirm that machine learning approaches can classify the hybrid analysis model with high accuracy rate (98%) than classifying static or dynamic individually.

Published: May 2020

In this report, the effects of homogeneous-heterogeneous autocatalytic chemical reaction together with the variable thermal conductivity in the Maxwell fluid flow due to nonlinear surface of variable thickness are investigated. Thermal radiation and heat generation / absorption effects are also incorporated in the analysis. Appropriate scaling analysis is implemented to reduce the mathematical model describing the physics of the problem in to a set of nonlinear differential equations and are subsequently solved computationally. Graphical illustrations indicating the effect of pertinent parameters on momentum, thermal and solutal boundary layers are presented and discussed. The study reveals that velocity distribution shows a decreasing (increasing) tendency for larger values of wall thickness parameter when the velocity power law index is less (greater) than unity. The concentration of the homogeneous bulk fluid with catalyst at the surface decreases with increasing chemical reaction rate parameters.
Machine learning applied to geoscience: Geo-referenced character recognition

Published: May 2020

Significant quantities of non-digital geoscience data exists on maps. In many cases this information has been scanned and is available in a raster format, but remains irretrievable for digital operations. This information may be in both a text and symbol format
and it is also necessary to capture the georeferenced location. In many cases this data may also consist of handwritten characters, which have much greater variability than typed characters. An example of such a dataset is handwritten depth soundings that are a common aspect of Canadian Hydrographic
Service (CHS) field sheets. CHS maintains a collection of scanned and georeferenced digital image files with handwritten depth soundings recorded directly on lake maps. To make use of this data for digital 3-D modelling, it needed to be converted to geo-referenced vector data. To avoid the
time-consuming process of entering thousands of data points, a machine-learning algorithm was applied to automate the digitization process using open-source software. Robust machine-learning libraries available in Python were integrated within a custom work environment for this application. This is
an example of how analogue geoscience datasets can be captured in a cost effective, timely and reliable manner.
Improved analysis of horizontal-to-vertical spectral ratio measurements for groundwater investigations
Authors: Dietiker B , Hunter J A , Pugin A J -M
Published: May 2020

Ambient seismic noise, and specifically the Horizontal-to-Vertical Spectral Ratio (HVSR), is routinely used for seismic microzonation, assessment of earthquake site characteristics and bedrock depth information for hydrogeological studies. These measurements not
only provide peak frequency or period of a seismic resonator, but the shape of the spectral ratio can also give insight into the architecture of subsurface structure. For example a dipping resonator decreases the peak amplitude and increases the peak frequency of the spectrum. Effects of
two-dimensional (2-D) subsurface structure (non-horizontal layering) have been successfully modelled and can be observed on the orthogonal Horizontal-to-Vertical Spectral Ratios, where N-S/V and E-W/V have different peak frequencies and peak amplitudes. By analysis of both horizontal spectral ratios
the practitioner is able to determine whether one-dimensional (1-D) subsurface layering is present and hence 1-D assumptions are appropriate, e.g. inverting shear-wave velocities (Vs), calculating average Vs and depth to the resonator. HVSR measurements collected along seismic reflection profiles
with known resonator topography, e.g. over steeply dipping bedrock resonators, are used to investigate both orthogonal horizontal components separately. Differences between the orthogonal H/V components are able to identify 2-D subsurface structure. Results demonstrate that extending analysis beyond
the peak frequency to include orthogonal Horizontal-to- Vertical Spectral Ratios adds important information related to dipping surfaces and their orientations. Due to the ease and rapidity of HVSR data collection, the technique is ideally suited for reconnaissance scale survey work but also for
infill where other data is sparse.

Published: May 2020

A prototype groundwater- surface-water model for southern Ontario has been developed with HydroGeoSphere (HGS), which provides a three-dimensional (3-D), physics-based simulation of fully integrated groundwater-surface-water flow. To-date, the model has been
tested for its ability to reproduce average monthly surface-water flow rates and groundwater levels, and its sensitivity to spatial and temporal resolution. Model utility has been demonstrated through an assessment of groundwater extraction influences on regional groundwater levels, which
demonstrates how it could be used to address water resources and hydrologic questions. The model domain encompasses 109,565 km2, with approximately 79,000 km2 being land area and the remainder being area within the Great Lakes. To assess sensitivity to spatial resolution, low- and high- resolution
model versions have been constructed, with surface water features resolved to Strahler order 4 and Strahler order 3, respectively. The hydrostratigraphy is based on 3-D Paleozoic and Quaternary geological models, along with mapping of depth to the base of high-sulphur content groundwater. The low-
and high- resolution models consist of 21 and 16 layers, and 874,398 and 2,127,760 3-D finite element mesh nodes. Both models incorporate spatially distributed soil, landcover, and spatially and temporally distributed evapotranspiration. To assess model performance, 321 wells from the Provincial
Groundwater Water Monitoring Network and 29 hydrometric stations from the Water Survey of Canada were incorporated as validation targets. Simulation results show that both the low- and high- resolution versions of the model were able to capture the magnitude and seasonal variation in both
groundwater levels and surface water flow rates. As the model was subjected to minimal calibration, this is a meaningful validation of its performance. Differences in performance between the low- and high- resolution model versions were minimal for both the surface-water flow rates and groundwater
level results. Results demonstrate the utility of a regional scale, fully integrated hydrologic model for investigating water resources issues of southern Ontario. The model could evolve into a multi-objective groundwater/surface-water simulation tool for southern Ontario, wherein seasonal water
balances and general trends in groundwater and surface water availability under climate change and anthropogenic influences within the Great Lakes Region can be assessed.
The extinction of the Ukrainian culture of the Polish-Ukrainian-Slovak borderland and the image of the “Ukrainian Banderite” in Polish and Czechoslovak literature, journalism and cinematography, mid-1940s–1980s
Authors: Drozd Roman , Šmigeľ Michal
Published: May 2020

The aim of this study is to outline the process of the extinction of Ukrainian culture in south-eastern Poland as a result of Polish resettlement actions and the activities of the Ukrainian underground movement (i.e., the Ukrainian Insurgent Army) in the post-war period (1944–1947). Concurrently, the study offers an analysis of the image of the “Ukrainian Banderite”, created by propaganda in Polish and Czechoslovak literature, journalism, and cinematography in the period from the mid-1940s to the end of the 1980s. The authors state that both in Poland and in Czechoslovakia the analysed topic has been subject to certain cyclical waves of interest, or current political demand or usefulness, but always according to an established and politically accepted template. The black-and-white reception of the issue, propaganda fictions, the concealment of facts, and the disproportionate highlighting of others, which were applied in the literary and film production of the real-socialist period, only distorted the historical objectivity of the issue and created a complicated stereotype in the collective memory.

The particular case analysed is the damages caused by earthquakes in the medieval fortifications of Almeria and the consequences on their conservation. Almeria is a zone of important seismic activity. This particularity has caused many problems to conserve its Islamic military architecture. Within this work, we include the most important earthquakes that have affected this heritage since the late fifteenth century and the constructions damaged –to a greater or lesser extent– by them, including their specific damages and an approach to their state of conservation. Due to its importance within the military constructions, we present the case study of the Alcazaba of Almeria and the wall of La Hoya, focusing on the second one. These paradigmatic constructions were widely affected by the earthquakes since the late fifteenth century. Beyond the analysis of the damages caused by the earthquakes and the different historical restorations to mitigate them, we include the emergency measures proposed in the framework of the PREFORTI Project for its better conservation against the different risks, as well as the microzonation mapping of the natural seismicity risk for the section of the wall of La Hoya in order to delve in the study of the vulnerability of this cultural asset against this natural risk, as a mechanism for its better preventive conservation.

Multidisciplinary integrations: history, survey and representations of the castle of Palmariggi in Terra d’OtrantoThe contribution integrates historical readings, conducted through archive documents and iconographic materials, with surveys and graphical analyzes carried out through direct knowledge of Palmariggi’s historic center in Salento. The imposing Aragonese castle of which today only the two cylindrical towers remain, joined together by a stretch of perimeter masonry, initially presented a quadrangular plan with four corner towers, of which three are cylindrical and one is square and was surrounded by an existing moat, until the middle of the twentieth century, with a wooden drawbridge on the eastern side. The fortress was part of a strategic defensive system, designed to protect the village and the productive Otranto’s land with which it was related. The fortified Palmeriggi’s center represented an important defensive bulwark placed within the network of routes and agricultural activities that led from the hinterland to the port of Otranto, where flourishing trade took place. The research examines the changes undergone by the defensive structure that has had several adaptations made initially in relation to changing military requirements, resulting from the use of firearms, the upgrades that were supposed to curb the repeated looting and the military reprisals against the inhabited coastal and inland centers of Salento peninsula, and later social that led to the expansion of fortified village with Palazzo Vernazza’s (eighteenth century) adjacent construction and the original parade ground’s elimination. Summing up, the contribution in addition to documenting the current situation with integrated surveys, the state of preservation of fortified structure with its village, of which it examines the urban evolution based on the construction, typological and morphological systems, relates to the surrounding territory by comparing the plant of the ancient nucleus with that of neighboring fortified Salento’s centers. Finally, digital study models allow fortified structure’s three-dimensional analysis, its construction techniques, assuming the original shape.
Architetture difensive nelle valli dello Ziz e del Todhra in Marocco

Published: May 2020

Defensive architecture in the Ziz and Todhra valleys in MoroccoThe earthen architecture of the Todhra and Ziz Valleys in Southern Morocco takes us back to the basic and archetypal forms of building in the Mediterranean. Architectural typology and language together form a cultural background that is strongly rooted in the territory and its inhabitants: the Berbers. The architectures, fragile and in constant decay, represent a treatise of living architecture in which the shapes, proportions and decorations are repeated over time with continuity.This research tries to verify, with data coming from direct and instrumental surveys, the quality and diffusion of the architectures that dot the valleys of the Todhra and the Ziz which, at same time, host the population and defend the most precious asset: water.  Along the valleys, united by the same language, we find: igherm, fortified citadels; tighremt, fortress houses.
The Aquila tower: a part of the Renaissance coastal defence system of Pučišća

At the end of the fifteenth century the Ottoman Empire won the land at the middle of the eastern side of the Adriatic, between the town of Omiš and the Neretva River. Thus exposing the northern settlements of the island of Brač, which were under the Venetian Administration at the time, to immediate danger from the Turkish invasion. The settlement of Pučišća was particularly vulnerable. Therefore, the settlement was intensively fortified, and a series of thirteen individual small coastal towers was built, after which the entire settlement was named Castello Pucischia in 1600. One of these towers –the Aquila tower– had a key role in defending Pučišća during the Ottoman-Venetian War, also known as the War of Cyprus (1570-1573). The Aquila tower was built at the beginning of the sixteenth century and today it is a well-preserved detached building situated on the Pučišća coast. Despite all the damage and transformations endured in the past, all the tower elements have been sufficiently preserved to reconstruct its original appearance, including the residential character of the overall interior: a stone wardrobe and a built-in stone basin (Cro. pilo), a fireplace, stairs, as well as those of a defensive character: mechanisms for lifting the drawbridge, loopholes, cannon openings, channels for extracting gunpowder smoke. The wooden beams’ supports in the walls above the first floor have also been preserved, as well as the barrel vault over the ground floor and the groin vault over the second floor which are still intact even today. On the external of the tower, the original corbels of machicolations as well as the semi-circular cornice above the escarp are partially preserved. By analysing the remains of the tower and by studying historical and bibliographic sources, a reconstruction of the original appearance of the Aquila tower has been made, both for the external and internal part, including transformations that took place over the time, since its construction to the present day. This has contributed to the knowledge of the typology of Renaissance coastal fortifications as well as to providing basis for potential renovation and reconstruction of the Aquila tower.

From Diego de Vera to Juan Martín Zermeño: three centuries of alterations in the architecture of the old castle of Rosalcazar in Oran, AlgeriaThe ancient castle of Rosalcazar is a military architecture that is part of the Oran’s defensive system, in Algeria. His structure was built in the sixteenth century by Diego de Vera, and it reflects the approaches of the Spanish fortification of the reign of Ferdinand the Catholic. These constructions were increased with later alterations, until their consolidation during the term of the governor and engineer Juan Martín Zermeño. The architectural ensemble represented an interesting evolution of the Spanish fortification since the beginning of the sixteenth century until the middle of the eighteenth century, preserving each extension of the elements of the prior period that they are shown in the heritage ensemble of maximum interest.
The Citadel of Turin: geometric design and underground archaeological evidence
Authors: Spallone Roberta , Zannoni Fabrizio
Published: May 2020

The Citadel of Turin (1564) is one of the first pentagonal modern fortification. For over two centuries it was the fulcrum of Turin defences, finally unarmed and largely dismantled during the second half of the nineteenth century. However, the lower sections of main defences and detached works were spared and buried inside the filled ditches, as well as the underground countermine system. Significant historical drawings, documenting the building of external defences are selected aiming to recognize geometric criteria that rules the subsequent phases, and to relate the designed fortification with the archaeological evidence.
La forma original del Cubete del Alcázar Real de Carmona
Authors: Almagro Gorbea Antonio
Published: May 2020

The original shape of the Cubete of the Alcazar of CarmonaAmong the works of the so-called “transitional” military architecture from the last quarter of the fifteenth century, one of the most unique cases erected in the Iberian Peninsula is the Cubete of Carmona (Seville). This bastion built in the times of the Catholic Monarchs follows the new poliorcetic standards, but with forms, which are quite innovative and could be considered breakthrough. Conceived as a bastion external to the Alcázar Real, it has a moat in part connected with the moat of the main fortress. The bastion is open in the rear, and could be consider a ravelin, although its location is in an angle of the outer enclosure of the Alcazar, which preludes the subsequent pentagonal bastions. Its anomalous plan is a horseshoe shape that has been discussed by various authors, but so far, there has never been a fully detailed survey with elevations and sections, nor, above all, an attempt to address their hypothetical reconstruction. This paper presents new plans, sections, elevations and images that proves this work is unusual and truly revolutionary for its time.
