Full textAbstract:
Access control models are often an orthogonal activity when designing, implementing, and deploying software applications. Role-based access control (RBAC) which targets privileges based on responsibilities within an application and mandatory access control (MAC) that emphasizes the protection of information via security tags are two dominant approaches in this regard. The integration of access control into software modeling and analysis is often loose and significantly lacking, particularly when security is such a high-priority concern in applications. This article presents an approach to integrate RBAC and MAC into use-case, class, and sequence diagrams of the unified modeling language (UML), providing a cohesive approach to secure software modeling that elevates security to a first-class citizen in the process. To insure that a UML design with security does not violate RBAC or MAC requirements, design-time analysis checks security constraints whenever a new UML element is added or an existing UML element is modified, while post-design analysis checks security constraints across the entire design for conflicts and inconsistencies. These access control extensions and security analyses have been prototyped within a UML tool.

In the process of requirements modeling based on ontology, the obtained model description is based on application ontology; which is not easy for designer to understand and cannot be converted into requirements specification documents for design. UML is actual standard for object-oriented modeling. For this issue, this paper creates the UML meta-model, and establishes mapping rules description language for application ontology to UML meta-element, which implements the generation of UML class diagrams based on rule, use case diagrams, state transition diagram models and requirements specification documents based on UML.

Full textAbstract:
Role of UML Class Diagram in Object-Oriented Software DevelopmentUML is an industrial standard for object-oriented software specification which offers a notation for class modeling during object oriented software development. Since the UML class diagram is a so-called "bridge" between software specification at the user side and software realization at the developer side, it requires strong guidelines for identification of class objects from the problem domain and notational conventions for modeling of the class diagram for its further usage in system coding. This paper presents a discussion on problematic stages and possible element transformations into software components. Several conclusions are drawn on potential usage of the class diagram in industry.

The growing interest of companies in integration and interoperability between information systems has caused increase in significance of Service-Oriented Architecture which provides tools for Enterprise Application Integration. In that architecture, Enterprise Service Bus provides technical possibilities of communication between IT systems. A key element in the communication are integration flows. Objective: The aim of this article is to present a new transformation Integration2BPEL, which automates the development of executable integration flow expressed in the Web Services Business Process Execution Language (WS-BPEL) based on the model of the integration flow presented in the Unified Modelling Language (UML) activity diagram. Method: The author proposes a transformation of the type of model-to-code type which generates integration flow expressed in WS-BPEL, which can be executed in any BPEL-compliant process engine. The integration flow is modelled using UML activity diagram with stereotypes from ‘UML Profile for Integration Flows’ profile in an IBM Rational Software Architect (RSA). Using Integration2BPEL transformation a complete, executable integration flow is generated, which is composed of many mediation mechanisms. Generated integration flows have been executed on OpenESB. Results: The ability to generate a complete integration flow in BPEL, which without any additions can be run on enterprise service bus. Implementation phase of an integration flow construction was automated. Each of integration flows is implemented according to the same rules. In addition, it allows to avoid mistakes made by designers and programmers. Conclusions: Model-Driven Development is an approach that leads to the automation of the design and programming phases. Integration2BPEL transformation is a uniform mechanism to design integration flow. Potentially, it also allows to avoid implementation errors. Keywords: Web Services Business Process Execution Language (BPEL), Enterprise Service Bus (ESB), Unified Modelling Language (UML), UML activity diagram, Model-Driven Development (MDD), Transformation. null

Design plays a key role in the development of software. The quality of design is crucial and is a fundamental decision element in assessing the software product. The early availability of design quality evaluation provides a better way to decide the quality of the final product. This avoids presumption in the quality evaluation process. Hence Software Metrics provide a valuable and objective insight of enhancing each of the software quality characteristics. This paper proposes a quality model to assess the design phase of any object-oriented system based on the works of Chidamber, Kemrer and Basili and suggests two new metrics. The research focuses on analyzing a set of metrics, which has direct influence on the quality of the software and creating a metrics tool based on Java that can be used to validate the object-oriented projects against these metrics. The analysis is carried out on a set of real world projects designed using Unified Modeling Language, which are used as test cases. These metrics and models are proposed to add more quality information in refining any object-oriented system during the early stages of design itself.

Pengembangan Rekayasa Perangkat Lunak berorientasi Objek, saat ini menggunakan tools pemodelan desain yang sesuai dengan model perancangan aplikasi sistem berorientasi objek. Dalam membangun suatu aplikasi sistem berorientasi objek atau berorientasi langsung dengan para pengguna (Users), maka tools yang tepat untuk di gunakan sebagai tools perancangan aplikasi sistem berorientasi objek yang dapat menggambarkan model proses (blueprint) dari suatu Rekayasa Perangkat Lunak Berorientasi Objek ialah Unified Modeling Language (UML). Unified Modelling Language (UML) adalah suatu metode dalam pemodelan secara visual yang digunakan sebagai sarana perancangan sistem berorientasi objek. Awal mulanya, UML diciptakan oleh Object Management Group dengan versi awal 1.0 pada bulan Januari 1997 [13]. Pada September 1997 lahirlah Unified Modeling Language (UML) versi 1.1 dengan 8 buah diagram, Pada tahun 1999 lahirlah Unified Modeling Language (UML) versi 1.3, menjadi 9 buah diagram, dengan penambahan “Business use case Diagram”, Pada bulan Mei 2001 lahirlah Unified Modeling Language (UML) versi 1.4, menjadi 10 buah diagram, dengan penambahan “Object Diagram”, Pada tahun 2002 lahirlah Unified Modeling Language (UML) versi 2.0, menjadi 13 buah diagram, dengan penambahan menjadi 13 buah diagram [1]-[3]. Model diagram proses yang dapat di kembangkan atau dibangun menggunakan Unified Modeling Language (UML) ialah Use Case Diagram, Business Use Case Diagram, Activity Diagram, Sequence Diagram, Object Diagram, Class Diagram, StateChart Diagram, Collaboration Diagram, Component Diagram, Deployment Diagram, Composite Structure Diagram, Interaction Overview Diagram, Package Diagram, Timing Diagram. Unified Modeling Language (UML) diharapkan mampu mempermudah pengembangan perangkat lunak serta memenuhi semua kebutuhan pengguna dengan efektif, lengkap, dan tepat. Hal itu termasuk faktor-faktor scalability, robustness, security. Adapun tujuan dan fungsi perlu adanya Unified Modeling Language (UML) yakni (1) Dapat memberikan bahasa pemodelan visual atau gambar kepada para pengguna dari berbagai macam pemrograman maupun proses umum rekayasa, (2) Menyatukan informasi-informasi terbaik yang ada dalam pemodelan, (3) Memberikan suatu gambaran model atau sebagai bahasa pemodelan visual yang ekspresif dalam pengembangan sistem, (4) Tidak hanya menggambarkan model sistem software saja, namun dapat memodelkan sistem berorientasi objek, (5) Mempermudah pengguna untuk membaca suatu sistem. Dan Unified Modeling Language (UML) berguna sebagai blueprint dalam perancangan berupa coding suatu program. Software yang dapat menggambarkan Unified Modeling Language (UML) ialah Aplikasi StarUML. Aplikasi StarUML dapat digunakan untuk membuat suatu alur atau proses dari suatu prosedur program yang ingin dibuat dengan cara menggambarkan model perangkatnya. Didalam StarUML terdapat beberapa bagian utama dari Unified Modeling Language (UML) yaitu view, diagram, model element, dan general mechanism.

Full textAbstract:
The development of code for finite elements-based field computation has been going on at a pace since the 1970s, yielding code that was not put through the software lifecycle – where code is developed through a sequential process of requirements elicitation from the user/client to design, analysis, implementation and testing and release and maintenance. As a result, today we have legacy code running into millions of lines, implemented without planning and not using proper state-of-the-art software design tools. It is necessary to redo this code to exploit new object oriented facilities and make corrections or run on the web with Java. Object oriented code’s principal advantage is reusability. Recent advances in software make such reverse engineering/re-engineering of this code into object oriented form possible. The purpose of this paper is to show how existing finite element code can be reverse/re-engineered to improve it. Taking sections of working finite element code, especially matrix computation for equation solution as examples, we put it through reverse engineering to arrive at the effective UML design by which development was done and then translate it to Java. This then is the starting point for analyzing the design and improving it without having to throw away any of the old code. Using auto-translators and then visually rewriting parts by the design so revealed, has no match in terms of speed and efficiency of re-engineering legacy code.

This paper gives the Petri net ontology as the most important element in providing Petri net support for the Semantic Web. Available Petri net formal descriptions are: metamodels, UML profiles, ontologies and syntax. Metamodels are useful, but their main purpose is for Petri net tools. Although the current Petri-net community effort Petri Net Markup Language (PNML) is XML-based, it lacks a precise definition of semantics. Existing Petri net ontologies are partial solutions specialized for a specific problem. In order to show current Petri net model sharing features we use P3 tool that uses PNML/XSLT-based approach for model sharing. This paper suggests developing the Petri net ontology to represent semantics appropriately. This Petri net ontology is described using UML, Resource Description Framework (Schema) RDF(S) and the Web Ontology Language-OWL.

Full textAbstract:
The issues of possibility of application of the code reuse mechanism in the process of designing and developing software of knowledge-oriented systems have been considered. The necessity of an individual research on the development of software for analytical and information resources that provide support to all participants in the process of knowledge-oriented systems software development has been proved. The necessity of using the mechanisms of reuse of previously developed and verified program code as an element of the information resource has been shown. In frame of the developed method of improving the reliability of knowledge-oriented systems software through the of code reuse mechanisms, a new visual form of function libraries representation in the shape of a single software shell has been proposed. As a basic framework for solving the problem of information resource development, usage of Unified Modeling Language (UML), which is based on the paradigm of object-oriented programming has been proposed. Mentioned choice is justified by the fact that UML is an integral part of a unified software development process and is essentially an open standard that uses graphical notation to create an abstract model of the system. The obtained theoretical provisions are imaged into a running example, which shows one of the possible options for organizing libraries of functions as an element of the information resource. The use case diagrams, interaction diagrams, sequence diagrams, class diagrams have been developed and justified. Based on the obtained practical results, a block diagram of the method, which, in contrast to existing solutions, includes a procedure for generating of proofreads for basic UML-diagrams in accordance with requirements of the programming environments has been proposed.

Full textAbstract:
Employees as one element in a company have rights and obligations to the company. One of the rights for employees is leave or permission for a certain time. The obligation of a company is to provide such leave or permission. In the process of applying for leave or employee permits so far, many use conventional processes. Conventional here means still using a form in the form of a sheet of paper leave or permission and must be sent to various parties for approval. This will take a long time and is not in line with the Go Green Program that is being carried out by many companies. Reduce, Re-use, Recycle and Replace are the four concepts of the Go Green program. Replacing the application for leave or permission that has been using a form (paper) by using a web-based application program is a step forward by the company to implement the Go Green concept. Web-based application programs in addition to reducing paper usage also do not require large physical data storage areas. This can be realized by making a web-based leave application which is certainly easier in terms of access to all employees. Meanwhile, data storage can be stored in cloud storage media. In this study, an application design will be made using UML (Unified Modeling Language) to be used as a reference during development. UML provides many diagrams, but in this study only a few diagrams were used. The results of the study indicate that application design using UML can facilitate communication between stakeholders, can make it easier for programmers to translate into programming languages. Using UML can reduce application creation errors and speed up completion.

Full textAbstract:
The final executable code should no longer be considered as a central element in a software development process but rather a naturally important component that results from a model transformation. The objective of the MDA (Model Driven Architecture) approach is to lift the lock of software development automation from the CIM (Computation Independent Model) requirements until the code of an application is obtained. Therefore, we have proposed in the framework of MDA an approach that consists of automatically generating object-oriented code from the CIM model represented by ReLEL (Restructuring extended Lexical Elaborate Language). ReLEL is a natural language-oriented model that represents both the client requirements and the conceptual level of a system. However, the MDA framework does not recommend the type of UML model that corresponds to each business activity. Consequently, automating the software development process from the CIM model specified by ReLEL becomes a complex task. Our strategy in this paper includes the instantiation of the ReLEL model in the Praxeme methodology, which models each of the company's concerns, grouped in a homogeneous whole, using the UML (Unified Modeling Language) and which considers the articulation of these aspects by adopting the MDA principle. To do this, we propose to automate the articulation that covers the intentional, semantic, logical, and software aspects of Praxeme. To validate our approach, we measure the coupling and cohesion of the UML class diagram obtained from the Java code generated from this article using the slicing technique. The results show that the coupling is weak, and the cohesion is strong. It can be deduced that the method proposed in this paper can produce a more reliable and efficient system.

The project is devoted to calculating the number of losses of medieval armies using artificial intelligence methods. Several possible calculation methods have been considered, and historical sources have been analyzed. The analysis of factors that affected combat and non-combat losses and the analysis of scientific and popular science literature have been carried out, and the methods proposed by specialists have been translated into the language of formulas. The process of building neural networks, selecting their architecture, searching and synthesizing data for training samples have been considered, and the process of training and verifying the obtained data have been considered. Two models of neural networks and an information model in the form of UML diagrams of the future web application have been developed. Diagrams of use cases, classes, and components for each element of the web system have been described. The models have been implemented using the modern Django framework. A full-fledged web application with microblogging has been developed and tested. The conclusions have been drawn about the efficiency and scalability of the developed system, and the functionality of the system has been demonstrated using a real historical example.
The project has developed the models of an information system for analyzing the number of troops and calculating military losses of the remote past. Mathematical models have been described, historical sources have been analyzed, and detailed models of the application have been created using the UML modeling language, which allows you to understand its interface in detail at the modeling stage.
Based on the data obtained in the analysis of historical literature, the neural network architectures have been developed to determine non-combat losses in the medieval army and determine combat losses based on the data on the number of each branch’s soldiers of the armed forces who were involved during the battle.
Web applications for calculating combat and non-combat losses have been developed, interface design and mini-block for publishing system News have been developed either. The non-combat losses suffered by the Mongol army in the first month of the Western campaign (1236) have been calculated as the example.

<em>Service orientation is an approach in the field of enterprise architecture, business information systems and software application that its main element is the service. Shared services is an organization model of sharing, across an organization. It enables collaboration among the functions/departments. Main motivations for shared services are sharing, promote efficiency, reduce cost, and support scalability. Despite of the widespread use of these two approaches in information technology, there is no tool to optimize the management of them. The aim of this study is Ontological map of service oriented architecture based on zachman framework to adapt it in the reference enterprise architecture framework through implementation ontology views on system architect software and as well as equivalent ontology component with UML diagrams. After the implementation of the suggested model, the results showed that ontology is a formal description and explicit display of objects, concepts and other entities in the relationship between them. In other words, there is a model that describe all that is in fact in to understandable language for the system. Thus the proposed establishes have association between all aspects of zachman framework, also to create a clear description of business concepts in the management of shared services and is effective to provide a unified platform for enterprise modeling.</em>

Abstract Roost selection in mammals is an important selective pressure, and many animals find shelter in previously existing structures. Furthermore, the microclimate of roosts is a crucial element for bat survival, and modified leaves are used for roosting (“tents”) by 22 species of bats. Our objective was to determine whether the inverted boat tents used by Ectophylla alba and pinnate tents used by Uroderma bilobatum provide energetic benefits. We measured the ambient temperature under modified and unmodified leaves (UMLs) of Heliconia imbricata and Cocos nucifera . We also measured temperature with (simulated bat presence) and without a heat source, and finally we measured bat energy expenditure at different temperatures. Our results show that when a heat source is present tents conserve heat better than a UML. The energy expenditure of E. alba and U. bilobatum increased up to 55% and 48%, respectively, with a decrease of temperature from 25°C to 20°C. We concluded that since the temperature at our study site drops below 25°C every night and remains that way until mid-morning, using a “tent” that maintains a temperature higher than ambient temperature, or close to 25°C degrees, provides an energetic advantage. La selección del refugio en los mamíferos es una presión selectiva importante y muchos animales encuentran refugio en estructuras ya existentes. El microclima del refugio es un elemento crucial para la sobrevivencia de los murciélagos. Las hojas modificadas (tiendas) son utilizadas por 22 especies de murciélagos. Nuestro objetivo era determinar si la tienda de bote invertido utilizada por Ectophylla alba y tiendas pinnadas utilizadas por Uroderma bilobatum brindan un beneficio energético a los murciélagos. Se midió la temperatura bajo hojas modificadas y no modificadas de Heliconia imbricata y Cocos nucifera . Además se midió la temperatura con fuente (simulando la presencia de murciélagos) y sin fuente de calor, finalmente se midió el gasto energético de los murciélagos a diferentes temperaturas. Los resultados muestran que cuando hay una fuente de calor presente, la tienda conserva el calor mejor que una hoja no modificada. El gasto energético de E. alba y U. bilobatum puede incrementarse hasta 55% y 48%, respectivamente, cuando la temperatura decrece entre 25°C y 20°C. Concluimos que como la temperatura en este sitio de estudio baja de los 25°C cada noche y hasta media mañana, utilizar una tienda que mantiene la temperatura arriba o cerca de los 25°C, provee una ventaja energética.

This article focuses on the case of the city of Kortrijk, Belgium, which in 2017 received the title of Creative City of Design from Unesco, especially the MyMachine, SPEK, and 5X5® Projects. The objective was to identify the main elements responsible for winning the title. To meet this objective, we opted for descriptive exploratory research, through bibliographic research. Among the results, it was possible to show that the city has come over the years, developing socially and economically based on its actions and strategies in the design and education, creative projects, and entrepreneurship, even long before being part of Unesco's World Network of Creative Cities. It was observed that Kortrjik has a driving role, mainly because it manages to create an innovation ecosystem with all the social actors involved in this process, highlighting the MyMachine, SPEK and 5X5® Projects, articulated with governmental, private initiative and civil society, giving the city a potential for relevant social innovation.

Assessment of the degree of level of IT specialists professional competencies when performing tasks in practice-oriented disciplines is an actual problem. Defects in functional requirements models created by students in object-oriented analysis affect the rest of the information system modeling stages. The aim is to study defects in UCDs. The tasks are study of the distribution of the number of types of defects and their number in UCD with a low level of detail, created by IT-students at the stage of object-oriented analysis; study of the relationship between defects of various types over several academic years in order to detect the influence of pedagogical influence on the density of defects. Statistical analysis methods using relationship scales are applied. As a result of the study of a corpus of 247 models for the period from 2016–2017 to 2021–2022 academic year, 2585 defects were identified. Their classification is used: lexical, syntactic and semantic. Types of defects are identified in each class. The study used indicators: the number of defects types and the number of these defects. As a result, it was revealed that the distributions of UCD defects indicators are not normal distributions. The use of a teaching aid with examples of creating UCD in the educational process, starting from the 2019–2020 academic year, has led to a steady decrease in the number of defects. This is confirmed by a statistically significant 95 % difference in indicators for a pair of academic years 2018–2019 and 2019–2020 according to the Wilcoxon–Mann–Whitney criterion. A positive aver-age relationship was found between the number of defects in the lexical and semantic classes in 2016–2017, 2017–2018 and 2021–2022 academic years. A positive strong relationship was found in the class of lexical defects be-tween types that refer to the attributes of one element of the model. In all other cases, no connection has been iden-tified that can be taken into account. The approach used can be applied to analyze other types of student UML models.

The element of unlawful (UMH – Unsur Melawan Hukum) in the Criminal Act of Corruption in the criminal justice practice shows a varied view between the prosecutor and the judge in making the decision to the defendant. The object of this study is related to the element of unlawful in corruption by using normative juridical method. The result shows that there are variations of the view is caused by (1) UMH, both formal and material, especially formal UMH in the criminal act of corruption is always seen as a bestanddeel element that gives character to other elements, with no prove UMH then other elements are considered unnecessary to be proved again, (2) UMH is considered as a stilzwijgend element which views each delict contained in UMH regardless of written or not in the formulation of a criminal article, but this leads to further debate which is necessary or not to be proved by the public prosecutor if UMH is not expressly written (as in article 2 paragraph (1) UUTPK) in the formulation of a criminal article. However, this is channeled by the view that if it is not clearly stated in the criminal article as in article 3 of UUTPK, it can be understood by applying genus-species approach to UMH as meant in article 2 paragraph (1) UUTPK as genus of UMH in TPK, then UMH its species in article 3 of UUTPK is understood from the element of misusing authority, opportunity, and position that existed on the corruptor.

Resumo Este estudo investigou como ocorreram a formação e a interação de um sistema econômico alternativo na comunidade Noiva do Cordeiro-MG com as dinâmicas da Economia Mercantil. Para atingir este objetivo, realizou-se uma investigação qualitativa valendo-se de uma etnográfica desenvolvida na comunidade rural. Baseado nas teorias da sociologia econômica de Marcel Mauss e de Karl Polanyi, este trabalho sinaliza que os aspectos da dádiva e da reciprocidade nas relações produtivas foram fundamentais para a reprodução de uma forte lógica solidária. Mediante princípios, estruturas e instituições muito próprios, em que o dinheiro tem uma importância bem limitada, os achados apontam que a comunidade desenvolveu um sistema diferenciado reproduzindo múltiplas lógicas econômicas, a despeito da tensão resultante de uma economia de mercado.

CP 6011, CEP 13083-970, E-mail: pater@agr.unicamp.br 1 RESUMO Durante ensaios para verificação de eficiência de retenção de algas em filtros de discos 120 MESH, tela 120 MESH e manta sintética não tecida, foram avaliados o grau de obstrução de gotejadores de labirinto com fluxo turbulento e vazão nominal de 4 L.h-1 e 8 L.h-1. Para determinação da obstrução causada por impurezas não retidas no meio filtrante foram avaliadas a evolução da vazão e da uniformidade estatística dos gotejadores submetidos aos diferentes meios filtrantes durante um período de 22 semanas durante 4 horas diárias e comparadas com uma parcela testemunha sem elemento filtrante. Os resultados mostraram que houve diferença significativa entre o elemento de discos, que apresentou maior uniformidade estatística, os filtros de manta e tela com valores intermediários e a testemunha que apresentou menor uniformidade estatística. No entanto, para caracterizar de maneira definida a diferença no desempenho dos elementos filtrantes, estes valores deveriam vir acompanhados de uma redução contínua na vazão média dos tratamentos, o que foi observado apenas para o elemento de tela com o gotejador de 4 L.h-1. As demais variações da uniformidade estatística foram temporais, provavelmente devido a obstruções temporárias ocasionadas por variações da concentração de sólidos suspensos na água de irrigação. UNITERMOS: Filtragem, Gotejamento, Qualidade da água. PATERNIANI, J.E.S.; SCATOLINI, M.E. EFFICIENCY OF DIFFERENT FILTER ELEMENTS TO PREVENT TRICKLE CLOGGING 2 ABSTRACT This work aimed to verify the efficiency of algae removal in disks 120 mesh, screen 120 mesh, and non woven synthetic fabric filters. It was evaluated the degree of clogging of turbulent flow drippers on 4 L.h-1 and 8 L.h-1 outflow. For blockage determination the outflow evolution and statistics uniformity (Us) of the dripper have been evaluated when submitted to different filter media over 22 weeks, 4 daily hours compared to a control without the filter element. The results indicated significant differences among the elements. The disk element presented greater statistic uniformity. The screen filter and the non woven synthetic fabric element presented intermediate values whereas the parcel with no filter element (control) presented minor statistic uniformity. However, in order to characterize performance differences among them, values should be presented along with a continuous average outflow reduction in all treatments. This pattern was observed only for the screen filter and 4 L.h-1 drippers. The statistics uniformity variation has been probably caused by temporary blockages due to variation in suspended solid concentration in irrigation water. KEYWORDS: filtration, drip irrigation, water quality.

The polygonal scaled boundary finite element method (PSBFEM) is a novel method integrating the standard scaled boundary finite element method (SBFEM) and the polygonal mesh technique. This work discusses developing a PSBFEM framework within the commercial finite element software Abaqus. The PSBFEM is implemented by the User Element Subroutine (UEL) feature of the software. The details on the main procedures to interact with Abaqus, defining the UEL element, and solving the stiffness matrix by the eigenvalue decomposition are present. Moreover, we also develop the preprocessing module and the postprocessing module using the Python script to generate meshes automatically and visualize results. Several benchmark problems from two-dimensional linear elastostatics are solved to validate the proposed implementation. The results show that PSBFEM-UEL has significantly better than FEM convergence and accuracy rate with mesh refinement. The implementation of PSBFEM-UEL can conveniently use arbitrary polygon elements by the polygon/quadtree discretizations in the Abaqus. The developed UEL and the associated input files can be downloaded from https://github.com/hhupde/PSBFEM-Abaqus.

Mineral nutrition for dairy cattle has advanced considerably in recent decades. The requirements, as well as the entire metabolism of each mineral element, have been demystified by science, attributing accuracy in the predictions of liquid requirements. These advances also allow us to understand the factors that influence absorption, metabolism and their impact on the animal's organism. Among the mineral elements, the macroelements represent the highest cost in the formulation of supplements and/or mineral cores, and often the excessive supplementation of these can cause serious damage to the cows, in addition to contamination of the environment. In this context, this review summarizes the main advances in mineral macroelements nutrition for dairy cattle, as well as their requirements, main sources, functions, absorption, excess and interactions with other mineral elements.

RESUMO Este artigo tem como objetivo demonstrar o caráter institucional do dinheiro e examinar as condições necessárias para preservá-lo como operador social. O dinheiro é uma instituição social, porque é central para a manutenção de práticas sociais necessárias para a criação de riqueza produtiva e, portanto, para a reprodução material das economias capitalistas modernas. Além disso, como o circuito produtivo é uma das esferas daquelas economias em que “paixões” privadas e “interesses sociais” podem ser reconciliados, o dinheiro é apresentado como um elemento de coesão social. Argumenta-se, no entanto, que somente se a confiança na manutenção da “unidade das funções do dinheiro” persistir, o dinheiro poderá ser preservado como instituição social. A confiança, em suma, mostra-se emergir de um processo cognitivo incorporado em padrões culturais específicos, nos quais as informações são geradas, transmitidas e reforçadas, gerando gradualmente hábitos e convenções a serem seguidos pelos agentes econômicos.

Full textAbstract:
An existing robust three dimensional finite element based on the strain approach is presented. This element is implemented, for the first time in the commercial computer code ABAQUS, by using the subroutine (UEL), for the static and dynamic analysis of isotropic plates, whatever thin or thick. It is Baptised SBH8 (Strain Based Hexahedral with 8 nodes) and has the advantage to overcome the problems involved in numerical locking, when the thickness of the plate tends towards the smallest values. The implementation is justified by the capacities broader than offers this code, especially, in the free frequencies computation. The results obtained by the present element are better than those given by elements used by ABAQUS code and the other elements found in the literature, having the same number of nodes.

Silicon nitride based ceramics have received considerable attention during the last decades due to their very good room and high-temperature properties. Ceramics such as silicon nitride (Si3N4) are acknowledged as first choice for modern bearing applications. The influence of grain bridging on the strength and toughness was found. The prediction of crack propagation through interface elements based on the fracture mechanics approach and cohesive zone model is investigated from amount damage models. Using cohesive models the behaviour of materials is realized by two types of elements. The former is the element for classical continuum and the latter is the connecting cohesive element. Within the standard finite element package Abaqus the new finite element has been developed; it is written via the UEL procedure. The shape of the traction separation law for experimental materials is estimated from macroscopic tests,J–Rcurve is predicted and stability of the bridging law is tested. The shape of the bridging law is verified using the microindentation test, where the maximum crack length not exceeded 150 μm. The scope of the bridging effect is verified using the standard XFEM elements implemented in Abaqus.

Introdução: A exploração do manganês no Amapá e o armazenamento inadequado dos rejeitos de minério na área portuária de Santana geraram impactos ambientais e sociais aos moradores locais. Objetivo: Avaliar a presença de elementos inorgânicos nas moradoras do bairro Elesbão expostas aos rejeitos de minérios. Método: Por meio da Espectrofotometria de Absorção Atômica de Chama (F-AAS), quantifcaram-se metais na água utilizada pela população e na matriz biológica urina, enquanto no cabelo utilizou-se Espectrometria de Massas com Plasma Indutivamente Acoplado (ICP-MS). Coletou-se o sangue de 67 mulheres expostas e de 99 não expostas, destas, coletou-se 65 amostras de urina e 18 de cabelo. Foram realizadas análises hematológica, bioquímica e de coagulação no sangue de todas as participantes que também responderam a um questionário socioeconômico. Resultados: Quanto à faixa etária, 60,0% das moradoras expostas estavam entre 18 e 42 anos e moravam na localidade entre 10 e 34 anos. Na água analisada, encontrou-se concentrações elevadas dos metais As, Cd, Cu, Fe, Mn e Pb. Na matriz urina, observou-se signifcância para o Mn e, no cabelo, para Pb e Mn. Dentre os parâmetros hematológicos signifcativos estavam Hb, Ht, VCM, HCM, monócitos, alterações morfológicas nas hemácias e plaquetas. Na avaliação bioquímica, observaram-se alterações nas enzimas fosfatase alcalina, bilirrubinas e creatinina. Conclusões: Há contaminação ambiental por elementos que podem comprometer a saúde da população exposta, quando em contato por tempo prolongado. Estudos mais aprofundados e direcionados à saúde da mulher precisam ser realizados, incluindo parâmetros como a análise de hormônios e marcadores genéticos, visando contribuir, assim, para uma ação das autoridades competentes em melhorar a saúde da população exposta.

Specific silicon nitride based materials are considered according to certain practical requirements of process, the influence of the grain size and orientation on the bridging mechanisms was found. Crack-bridging mechanisms can provide substantial increases in toughness coupled with the strength in ceramics. The prediction of the crack propagation through interface elements based on the fracture mechanics approach and cohesive zone model is investigated and from the amount of damage models the cohesive models seem to be especially attractive for the practical applications. Using cohesive models the behaviour of materials is realized by two types of elements. The former is the element for classical continuum and the latter is the connecting cohesive element. Within the standard finite element package Abaqus a new finite element has been developed; it is written via the UEL (users element) procedure. Its shape can be very easily modified according to the experimental data for the set of ceramics and composites. The new element seems to be very stable from the numerical point a view. The shape of the traction separation law for three experimental materials is estimated from the macroscopic tests, JR curve is predicted and stability of the bridging law is tested.

To accurately solve the fracture parameters of enamel, we have established computational nonhomogeneous enamel models and constructed the fracture element of enamel dumb nodes, based on the enamel mineral concentration, nonhomogeneous mechanical properties, and virtual crack closure technique. Through the commercial finite element software ABAQUS and the fracture element of the enamel dumb nodes, we have established the user subroutines UMAT and UEL, which enabled solving of the energy release rates of the nonhomogeneous enamel structure with cracks. The stress intensity factors of central cracks, three-point bend and compact stretched enamels, and double-edge notched stretched enamels are determined. By comparing them with analytical solutions, we have proved that the fracture element of the enamel dumb nodes is highly accurate, simple, and convenient. In addition, the cracks can be other elements rather than singular or special elements; they show versatility and other advantages. The stress intensity factor of the dental enamel can be solved more realistically. Thus, a new numerical method for prevention and treatment of dental diseases is provided.

Software models describe structures, relationships and features of the software system. Especially, in Model Driven Engineering (MDE), they are considered as first-class elements instead of programming code and all software development activities move around these models. In MDE, programming code is automatically generated by the models and models’ defects can implicitly transfer to the code. These defects can harder to discover and rectify. Model verification is a promising solution to the problem. The Unified Modelling Language (UML) class model is an important part of UML and is used in both analysis and design. However, UML only provides graphical elements without any formal foundation. Therefore, verification of formal properties such as consistency, satisfiability and consequences are not possible in UML. This paper mainly focuses on ontology-based transformation and verification of the UML class model elements which have not been addressed in any existing verification methods e.g. xor association constraint, and dependencies relationships. We validate the scalability and effectiveness of the proposed solution using various UML class models. The empirical study shows that the proposed approach scales in the presence of the large and complex model

Resumo O trabalho reconstrói a trajetória do Advocacy Coalition Framework (ACF), especialmente seu processo de aprendizado orientado à políticas públicas. Inicialmente, o texto contrasta os elementos contidos em Sabatier e Mazmanian (1980), nos quais são encontrados os primeiros esforços para desenvolver um modelo de análise com os argumentos encontrados em Sabatier (1987, 1988 e 1993). Posteriormente, a trajetória histórica de atualizações e versões do modelo é discutida com base nas análises de Sabatier e Jenkins-Smith (1999), Sabatier e Weible (2007) e Jenkins-Smith et al. (2018). Ao longo de mais de 30 anos de pesquisa, foi possível acompanhar as modificações presentes nas quatro versões do modelo, as principais hipóteses construídas, as críticas e seus desdobramentos Uma lacuna identificada nessa trajetória e consequente proposta para uma futura agenda de pesquisa apontam a influência dos atores internacionais e suas implicações nas modificações de políticas públicas, condição não explicitamente abordada pela ACF em suas diversas versões, conforme destacado por Jenkins-Smith et al. (2018).

Development of pseudo interface element for modelling of reinforced brick masonryABSTRACTStrength of reinforced masonry is influenced by interfaces between brick, mortar and reinforcement. Experimental protocol has been defined to characterise the behaviour of reinforced brick masonry joint, with reinforcement steel embedded in cement mortar 1:6. This is applicable for low-strength, low-stiffness brick masonry found. Experimental investigations show that bond between masonry and steel is not perfect. Considering critical bond mechanisms, an attempt is made to put-forth a novel approach for development of a pseudo interface element representing three different materials (viz. brick, mortar and reinforcement) and two interfaces (reinforcement-mortar (RM) interface and brick-mortar (BM) interface). Principles of classical Reinforced Concrete (RC) design can therefore be directly applied to reinforced masonry with the introduction of the proposed pseudo interface element.Keywords: reinforced masonry joint; interface element; masonry reinforcement bond behavior; pseudo interface material; stiffness of interface elements. Desarrollo de un pseudo-elemento de interfaz para el modelado de mampostería de ladrillo reforzado RESUMENLa resistencia de la mampostería reforzada está influenciada por las interfaces entre el ladrillo, el mortero y el refuerzo. Se ha definido un protocolo experimental para caracterizar el comportamiento de la junta de mampostería de ladrillo reforzado, con acero de refuerzo incrustado en mortero de cemento 1: 6. Esto es aplicable para la albañilería con ladrillos de baja resistencia y baja rigidez encontrada. Las investigaciones experimentales demuestran que el vínculo entre la mampostería y el acero no es perfecto. Teniendo en cuenta los mecanismos de enlace críticos, se intenta presentar un nuevo enfoque para el desarrollo de un elemento de pseudo-interfaz que represente tres materiales diferentes (ladrillo, mortero y refuerzo) y dos interfaces (de refuerzo y mortero (RM) y de mortero (BM)). Por lo tanto, los principios del diseño de concreto armado (RC) clásico pueden aplicarse directamente a la mampostería reforzada con la introducción del pseudo-elemento de interfaz propuesto.Palabras clave: articulación de mampostería reforzada; elemento de interfaz; comportamiento de enlace de refuerzo de mampostería; pseudo-material de interfaz; rigidez de los elementos de la interfaz. Desenvolvimento de um elemento pseudo-interface para modelagem reforçada alvenaria de tijoloRESUMOA resistência de alvenaria reforçada é influenciada pelas interfaces entre o tijolo, argamassa e de reforço. Definido um protocolo experimental para caracterizar o comportamento da placa reforçada alvenaria de tijolo com aço de reforço embebido em argamassa de cimento 1: 6. Isso se aplica a alvenaria de tijolo com baixa resistência e baixa rigidez encontrados. A pesquisa experimental mostra que a ligação entre a alvenaria e aço não é perfeito. Dada a mecanismos de ligação crítica, tenta apresentar uma nova abordagem para o desenvolvimento de um elemento de pseudo-relação representando três diferentes materiais (tijolos, argamassa e reforço) e duas interfaces (reforço e argamassa (RM) e argamassa (BM)). Portanto, os princípios de concepção de betão armado (RC) pode ser aplicado directamente sobre a alvenaria reforçada clássico com a introdução do elemento pseudo-interface proposta.Palavras-chave: alvenaria armada conjunta; elemento de interface; vinculativo de reforço comportamento da alvenaria; material de pseudo-relação; rigidez dos elementos de interface.

The chemical composition of detrital minerals in sediments has become a powerful tool for provenance studies, particularly in the last decades with the improvement of analytical techniques for mineral grains. Major and trace element contents of igneous and metamorphic minerals can reveal the characteristics of their original sources, mainly with respect to their geochemical affinity, geotectonic setting and the physical parameters that controlled their crystallization. The proportions of major elements in pyroxenes and amphiboles can be used for the identification of their igneous or metamorphic origin, for the definition of their magmatic affiliation, and for the discussion of the probable tectonic setting where they were generated. Metamorphic and igneous zircons can be distinguished by REE patterns or U and Th contents. Magmatic zircons from different geotectonic settings can show different concentrations of REE, Nb, Hf and Y. Magmatic garnets from granites typically show high Mn contents, and can be distinguished from metamorphic ones or from garnets of ultramafic rocks mainly through their major element composition. Compositional zoning of garnets are indicative of their metamorphic or igneous character. Magmatic, metamorphic and hydrothermal epidotes can be distinguished by their chemical composition, as well. Several other minerals, such as apatite, tourmaline, rutile, titanite, and feldspars can indicate, through their chemical composition, the probable rock that could have produced them. The integration of geochemical data on detrital minerals with other usual tools of sedimentary petrology is certainly the most efficient approach for investigating the provenance of sediments.

Abstract This paper aims to retrace the trajectory of the Advocacy Coalition Framework (ACF), especially its policy-oriented learning process. Initially, we contrast the elements in Sabatier and Mazmanian (1980), where the first efforts to develop an analysis model are found, with the arguments found in Sabatier (1987, 1988, and 1993). Subsequently, the historical trajectory of updates and versions of the model is discussed based on the analyses in Sabatier and Jenkins-Smith (1999), Sabatier and Weible (2007), and Jenkins-Smith et al. (2018). It was possible to follow the modifications in the model, the main hypotheses built, the criticisms, and their unfoldings. As main findings, it was evident throughout the ACF construction trajectory: four versions of the model over almost 30 years and with the decisive participation of six prominent authors who contributed to its main developments since the first version, present in Sabatier and Jenkins-Smith (1993); and Sabatier and Jenkins-Smith (1999), the model gains greater analytical capacity with the intermediate variables between the external factors and the policy subsystem and analytically refines the categories internal to the subsystem. One gap identified in this trajectory, and consequent proposal for a future research agenda, is the influence of international actors and their implications on policy modifications, a condition not explicitly addressed by the ACF in its varied versions, as highlighted by Jenkins-Smith et al. (2018).
