Bento Almeida d’Eça: Hydraulic Agriculture under the umbrella of Engineers in Nineteenth Century Portugal

In mid-nineteenth century Portugal, the practice of irrigation was deemed to be completely backwards in comparison with the prevailing European standards. Distant were the times of Al-Andalus, when a so-called green revolution occurred on the Iberian Peninsula. Within this context, Agricultural Hydraulics gained momentum as a scientific field. Although water governance had a long run, the ‘politicisation’ of water issues clearly intensified in the Regeneration political regime. From 1851 onwards, the stability required for national material progress was ensured. The country had been struggling to build roads, railways, telegraphs, ports and, therefore, the Ministry of Public Works was established in 1852 to undertake these architectural and engineering projects. This paper argues that not only due to rivers’ manipulation for agriculture, but also to the rising status of engineers, Agricultural Hydraulics was under the Ministry of Public Works and, consequently, on the sphere of engineers rather than agronomists. Focusing on the making of a military engineer as an expert on Agricultural Hydraulics by sending him abroad and fostering his literary education, this paper reveals how this knowledge was appropriated and transformed into new projects for the Tagus River. Moreover, contrary to recent review that Hydraulic Services were launched in Portugal by 1884, based on the “Plan for Organization of Hydrographic Services on the mainland of Portugal”, this paper highlights the crucial role played by the Portuguese engineer Bento Fortunato Almeida d’Eça through his work as Superintendent of the Tagus River and its Tributaries, twenty years earlier.

Effect of the Advanced Cranial and Craniofacial Implant Fabrication on Their Degradation Affinity.

Biodegradable craniofacial and cranial implants are a new aspect in terms of reducing potential complications, especially in the long term after surgery. They are also an important contribution in the field of surgical reconstructions for children, for whom it is important to restore natural bone in a relatively short time, due to the continuous growth of bones. The aim of this study was to verify the impact of the technology on biodegradability and to estimate the risk of inappropriate implant resorption time, which is an important aspect necessary to select prototypes of implants for in vivo testing. Prototypes of implants were made using two technologies: 3D printing using a PLDLA: poly(L-co-D,L lactide) (PLDLA) filament containing hydroxyapatite nanoparticles, and injection using PLDLA. After the radiation sterilization process, they were subjected to in vitro degradation under accelerated conditions. As part of this study, the in vitro degradation of newly developed biodegradable implant technologies was assessed in accordance with the guidelines of European standards. It was found that the implant manufacturing process had a significant impact on the degradation time under simulated conditions in various media. Implants made using the injection technique were characterized by lower susceptibility to degradation media compared to the 3D-printed implant under accelerated conditions.

The conclusion of the article states that the introduction of European standards of higher education in Ukraine is an important step in the direction of reforming the system of higher education and bringing it in line with the requirements of the modern world. Key words: European standards, higher education, culture of education quality, student-centered learning, tutor, autonomy of universities, challenges, opportunities, competitiveness.

Changes to the lambda model for fatigue loads on steel railway bridges in Europe

AbstractFor the fatigue design of steel railway bridges in Europe, the European standards EN 1991‐2 and EN 1993‐2 provide a factored Load Model '71, called the lambda model. The stress range in the fatigue detail of study should be determined with this model. Engineers can easily verify their structural design for fatigue by comparing this stress range to the fatigue reference strength of the detail.This paper compares the load effect caused by the lambda model with the load effect of actual trains measured with ‘Weigh In Motion’ systems during 7 years at 81 locations in the rail network of The Netherlands. Locations with heavy loads are selected and their load effects in terms of stress ranges and fatigue damage are determined for various influence lines, including one, two and three span beams with spans ranging between 1 and 150 m. The design (i.e. elastic section modulus) is optimized such that the calculated fatigue damage using the damage accumulation rule of Palmgren Miner equals 1 for a 100 years design life for these locations. This elastic section modulus is compared to the elastic section modulus obtained by designing according to the lambda model.Improvements are proposed to the lambda model based on this comparison, such that the resulting design gives a reasonable agreement with the design based on measured loads, while maintaining the current ease of use of the lambda model. Uncertainties such as possible changes in axle loads and train speeds in future are taken into account.

Web Bearing Test of Cold‐Formed Austenitic Stainless‐Steel Channels Under Interior Loading

AbstractDuctility, durability and high corrosion resistance of stainless steels make them appealing to use in construction industry. When used as structural sections, they are, however, subjected to localised failure in the web. This study aims to examine the structural behaviour of cold‐formed austenitic stainless steel channels under localised interior bearing loads. The results of 21 tests on unlipped channels with different cross section sizes and thicknesses are presented. Nonlinear quasi‐static Finite Element (FE) model is then developed. The FE model is validated against experimental test results and demonstrated good agreement in terms of bearing strength and failure modes. In addition, the experimental and FE results are used to compare the results against the results predicted in accordance with the American specification SEI/ASCE 8:2002 and European Standard EN 1993‐1‐4:2006. It is found that the current design equations are unreliable and too unconservative to use for cold‐formed austenitic stainless steel unlipped channels, especially when compared to SEI/ASCE 8:2002, as much as 41%.

Influence of Profiled Faces on the Overall Shear Performance of Strongly Profiled Sandwich Panel with Mineral Wool Core

AbstractThe total shear force induced on a profiled sandwich panel by an external load is distributed between the profiled face and core. Sandwich panel with a discrete core material such as mineral wool consists of multiple transverse lamella joints across the full width of the panel, affecting the overall shear performance of the panel as these joints have negligible resistance to shear. Additionally, in some cases the core material is partially bonded only to the lower flange of the profiled face which increase the concentration of stresses in the bonded area leading to the crushing of the core on the support. This work studies the distribution of shear force in mineral wool core sandwich panels with one profiled face utilizing a shear beam test on a specimen cut from the panel including the profiled part. Based on the results and failure modes obtained, this work investigates the behavior and role of the profiled face on the shear resistance of profiled sandwich panels. The distributed shear force between the core and profiled part obtained from the shear beam tests are compared with full‐scale tests suggested by the European Standard EN 14509:2013, thus, exploring the applicability of the devised shear beam test method for assessing the shear properties of profiled sandwich panel.

Lipidomic analysis of differently prepared platelet concentrates in additive solution during storage.

Structural and biochemical changes in stored platelets are influenced by collection and processing methods. Lesions may appear during platelet concentrate storage, some of which may be involved in adverse transfusion reactions. The preparation and storage of platelet concentrates (PC) may modify and even damage the lipid mediator content. The aim of this study was to investigate the lipidomic profile identified in the supernatants of PCs according to processing and storage conditions, both after leukocyte filtration and contained in platelet additive solution (PAS), comparing single donor apheresis (SDA) products with pooled buffy coat (BC) products. We investigated the accumulation of various lipid mediators including lysophospholipids (LP) and eicosanoids in SDA and BC products stored for 0-5 days. All products were processed following French Blood Establishment (EFS) procedures in accordance with EDQM/GTS European Standards. Both SDA and BC were leukocyte reduced and conserved in 35% autologous donor plasma and 65% platelet additive solution. Lipidomic analysis was performed on PC supernatants using LS/MS spectrometry. Our data demonstrate that lysophosphatidylcholine (LPC) levels were higher in BCs compared to SDAs, with no difference in lysophosphatidic acid (LPA) expression between the two preparation methods. Results for other eicosanoids showed greater similarity; indeed, no clear pattern emerged from analysis of eicosanoids in terms of storage time and process. In general, we observed longitudinal lipid mediator modulation for both SDAs and BCs, particularly at later time points. The expression of LPC and some eicosanoids in BCs could be used as novel biomarkers of PC quality. Future studies are needed to explore their impact on adverse transfusion reactions.

Analysis of the legal regulation of administrative conflict proceedings in European countries for the development of domestic legislation

The work proves that Ukraine’s integration into the European legal space requires a full-scale legal system reform based on the principles and standards formed at the pan-European level. It is extremely necessary to take into account international and European standards when carrying out reforms in public administration in Ukraine, as well as take into account theoretical provisions, doctrines, and positive practical experience of foreign states in the field of administrative conflict proceedings. The administrative-judicial reform announced by the President of Ukraine and the development of the normative framework for the regulation of administrative proceedings is taking place while considering international and European standards of administrative justice aimed at the settlement of conflict proceedings. The analysis of foreign doctrine and legislation in the field of administrative responsibility indicates the absence of a single model of legal regulation of this institution in foreign countries, where in some countries, it is part of criminal legislation, while in others, it is an entirely different sphere of legal regulation. In order to improve conflict legal proceedings, it is expedient to pay more attention to the international experience of regulating administrative proceedings. Despite the different attitudes to administrative and tort legislation in various countries, each country has its own important experience in conducting cases. It is possible to describe the following features of the systematization of legislation on administrative responsibility: some countries are focused on decodification, while others are moving toward adopting a single codified act. Also, quite often, we can observe differences in jurisdictional administrative procedures in foreign countries. However, the implementation of the experience of European countries in conflict proceedings will not only contribute to the improvement of domestic legislation but will also ensure close cooperation with the EU. The author proposes to use the experience of foreign countries regarding the expansion of the range of subjects of proceedings in cases of administrative offenses since, in most countries, legal entities can be brought to administrative responsibility on an equal basis with individuals. In this way, administrative justice would contribute to the strengthening of law and order in the state of Ukraine. Administrative justice is an integral feature of the rule of law state, and its creation is the task of every democratic state. Key words: administrative law, administrative process, administrative proceedings, conflicting administrative proceedings, simplified proceedings, administrative law of foreign countries, administrative law of EU countries, administrative tort law

Loadbearing versus non‐loadbearing fire walls

AbstractIn the last decades plenty of fire tests with wall constructions consisting of reinforced AAC elements were executed. Many of the test results have been transferred to European and national technical regulations. Also, theoretical methods to design reinforced AAC elements for fire impact are available. These provide temperature curves for the commonly used dry densities and procedures to calculate and rate the influence of fire stress on the functional capacity of the wall systems.In the last years additional fire tests took place to show the fulfilment of special requirements for buildings with high demands regarding fire safety. For example, tests with six hours of firing were performed which is highly above the definitions and solutions given in standards.Xella's R&D Center meanwhile has its own test stand to execute suitability checks for fire walls and is accredited for performing these tests.In the last years the question about how to rate the performance of fire walls on basis of test results came up, especially regarding load bearing walls. This is the result of different definitions in the relevant national and European standards. Possible approaches for solving this topic shall be presented at the AAC conference.

Economic assessment of corrosion prevention measures in new structures

AbstractChloride‐induced corrosion is a main cause of deterioration in reinforced concrete (RC). The premature deterioration of RC leads to unplanned repairs, hence elevating the direct and indirect costs of the RC infrastructure. The current prescriptive durability design approach has proven to be insufficient in assuring the durability of the RC exposed to chlorides. The objective of this study is an economical evaluation of several prevention measures for chloride‐induced corrosion following the performance‐based approach. A case study is inspired by a real set of RC columns, which suffered from chloride‐induced corrosion damage after 14 years in service. The considered prevention measures are the use of different binder systems, variation of the water/binder ratio, and changes in the concrete cover. To compare the obtained results, a reference design is set with a concrete mix and a cover thickness according to the requirements of the prescriptive approach described in the European standards. The results show that a balance between the binder type, concrete cover and water/binder ratio is necessary in order to optimize the costs while assuring the durability of the RC element.

Impact of Indoor Environmental Quality on Students’ Comfort in High School Buildings during the Summer Season in an Extreme Climate

Maintaining a satisfactory indoor environmental quality (IEQ) is an integral element of improving occupant health and well-being. In particular, IEQ is an essential factor in some facilities, such as school buildings, to improve student academic performance. This study employed an objective and subjective measurement approach to assess IEQ in a government high school (GHS) and a private high school (PHS) located in Oman, which is characterized by its extreme hot climate. A total of 212 high school students were surveyed during the summer season across 10 different classrooms to ascertain their perception of IEQ situations. The results suggested that most of the observed IEQ factors, including air temperature, relative humidity, and lighting levels across the classrooms in GHS and PHS, satisfied the ASHRAE standard, except the indoor air temperature, which was slightly above the maximum threshold of the European Standard (EN). The average indoor sound levels (>60 dB) exceeded critical limits of 35 dB for school buildings, which may pose the risk of high annoyance (HA) to 30% of students. Satisfactory predicted mean vote (PMV) and predicted percentage of dissatisfied (PPD) scores were obtained from both schools when they were evaluated against the ASHRAE standard compared with the EN standard. The maximum proportion of the students reported their classroom’s air temperature (33%), relative humidity (25%), and air movement (47%) levels as not acceptable, and thermal comfort (33%), visual comfort (22%), and air quality (41%) as bad (P < 0.001). Multiple regression analysis revealed a strong linear relationship between indoor air temperature (R2 = 0.89) and other IEQ parameters, while PPD (R2 = 0.45) and PMV (R2 = 0.17) showed a weak relationship with outdoor environmental factors. Outdoor air temperature and humidity levels accounted for greater changes in indoor air temperature levels in the PHS than in the GHS. Providing increased urban vegetation, green façade, and retrofitting and the utilization of passive cooling could help improve IEQ in Oman schools.

Structural response and design of stainless steel hollow section columns at elevated temperatures

AbstractThis paper investigates the flexural buckling behaviour and design of stainless steel circular, elliptical, square and rectangular hollow section (CHS, EHS, SHS and RHS) columns at elevated temperatures through numerical modelling. Shell finite element models are utilised to perform numerical parametric studies whereby benchmark structural performance data are generated. A large number of cold‐formed and hot‐rolled austenitic, duplex and ferritic stainless steel CHS, EHS, SHS and RHS columns at elevated temperatures are taken into account, considering various cross‐section and member slendernesses. Since the fire design provisions provided in the European fire design standard EN 1993‐1‐2 for stainless steel columns are largely based on those originally developed for carbon steel columns, they typically lead to rather inaccurate ultimate resistance predictions for stainless steel columns at elevated temperatures. To address this, in the present study, a new flexural buckling design method for stainless steel hollow section columns at elevated temperatures is put forward. The accuracy, safety and reliability of the proposed design method and the provisions in EN 1993‐1‐2 are assessed. It is observed that the proposed fire design method leads to more accurate, safe‐sided and reliable flexural buckling resistance predictions for stainless steel hollow section columns at elevated temperatures relative to the provisions in EN 1993‐1‐2.

Local buckling response and design of stainless steel hollow sections at elevated temperatures

AbstractThe structural behaviour and design of stainless steel hollow sections in fire, including stainless steel (i) circular hollow sections (CHS), (ii) elliptical hollow sections (EHS), (iii) square hollow sections (SHS) and (iv) rectangular hollow sections (RHS), are explored in this paper. Shell finite element models of stainless steel CHS, EHS, SHS and RHS able to replicate their structural response at elevated temperatures are created. Numerical parametric studies are performed on cold‐formed and hot‐rolled austenitic, duplex and ferritic stainless steel CHS, EHS, SHS and RHS subjected to (i) pure compression, (ii) pure bending, (iii) combined axial compression and bending and (iv) combined bending and shear in fire, covering different cross‐section slendernesses and elevated temperature levels. Calibrated against the benchmark structural performance data obtained from the numerical parametric studies, the new design proposals for predicting the ultimate resistances of stainless steel CHS, EHS, SHS and RHS in fire put forward in Quan and Kucukler [1,2] are set out. It is demonstrated that relative to the design recommendations provided in the European structural steel fire design standard EN 1993‐1‐2, the proposed cross‐section design methods provide more accurate and safe‐sided ultimate resistance predictions for stainless steel CHS, EHS, SHS and RHS at elevated temperatures.

Resistance and behaviour of carbon steel and stainless steel columns with axial and rotational end‐restraints in fire

AbstractDue to the presence of neighbouring structural elements, carbon steel and stainless steel columns are typically axially and/or rotationally restrained at their ends in fire. Despite the significant influence of the axial and rotational end‐restraints on the behaviour, the fire design rules for steel columns provided in the European structural steel fire design standard EN 1993‐1‐2 were originally developed considering the structural response of axially unrestrained steel columns with pin‐ended support conditions. Thus, EN 1993‐1‐2 may provide inaccurate ultimate resistance predictions for axially and/or rotationally restrained steel and stainless steel columns in fire. Considering this, this paper investigates the behaviour and design of carbon steel and stainless steel columns with axial and/or rotational end‐restraints at elevated temperatures. A number of carbon steel and stainless steel I‐section columns are considered, taking into account different axial and rotational end‐restraint stiffnesses, room temperature loading ratios, member and cross‐section slendernesses. A new design method for the fire design of axially and/or rotationally restrained steel and stainless steel columns is put forward. The accuracy of the proposed new design method is extensively verified against the results from nonlinear shell finite element modelling.

Reflections on the scientific basis of building-related acoustic standards

As with standards in other indoor-environmental quality, standards play also an important role in building and room acoustics field. They are typically expected to a) represent the state of the art in the respective area and b) arbitrate if a building's design and construction meets the mandated requirements. It is thus important to ensure that the standards' mandates are indeed based on sound scientific evidence. Given their utility as a source of guidance for practitioners, the standards of course need not be conceived as scientific treatises. Nonetheless, the respect for and trust in the standardization bodies and the documents they issue is arguably proportional to the strength of their underlying scientific basis. Given this presupposition, the main intention of the present contribution is to examine, via the review of 19 European, American, and international standards in the domain of building and room acoustic, if they provide, either directly or indirectly, evidence with regard to the included requirements and mandates. The results of this review suggest that the majority of the selected acoustic standards provide sparse references to the evidentiary basis of their mandates. Nonetheless, there are also contrary instances, where standards engage, to some degree, the experimental evidence underlying their mandates. A case study of such an instance displays the potential for future developments in developing explicitly evidence-based standards.

Performance Evaluation of a Novel Intrusion Detection System in Next Generation Networks

The integration of Internet of Things (IoT) with 5G simply creates additional threat landscape and any network infrastructure is more vulnerable. Severe attacks on networks potentially damage organization reputation, customers or tenants lose confidence, and impacts operational and maintenance cost. Intrusion detection systems (IDSs) are an effective approach to mitigate threats. We present a novel IDS mechanism in which the unique Radio Frequency (RF) features of IoT devices are used to create a learning model which is later used to identify the illegitimate devices in the network. Leveraging the Deep Autoencoder (DAE), the existing steady-state feature extraction is generalized. The performance evaluation is conducted using a real data set from different aspects including the mobility of the nodes. The proposed IDS is broken down into pluggable virtual network function (VNF) components and its evaluation is presented for its integration into the 5G network slicing ecosystem from the perspective of the European Telecommunications Standards Institute (ETSI) standards. A Proof of Concept (PoC) is presented using ETSI Open Source NFV Management and Orchestration (OSM-MANO) test bed, deployed on AWS cloud systems, to show how the proposed approach would fit in with a real-life MANO.

Evolution of EC 6—Influence on masonry constructions made from AAC

AbstractWithin the scope of developing a new generation of Eurocodes also the European masonry standards are subjected to an evolution. Thereby new drafts for all four parts of EN 1996 have been elaborated and the final versions are available. Aim of the evolution was to implement the application experiences of the actual version, improving the ease of use and reducing the number of National determined parameters. The most severe changes of the new versions of the standards are the modifications of the calculation methods in EN 1996 parts 1‐1 and 3. Especially for masonry walls with a compressive strength and for constructions with partly supported ceilings the new simplified calculation methods showed a significant difference in the maximum capacities. Basing on this finding the conditions and rules for the design of AAC masonry according to EN 1996‐3 were adapted and thus improved for the final draft. This was a result of a big number of comparing calculations which took into account the special properties and behaviour of AAC masonry especially the ratio between compressive strength and modulus of elasticity. Regarding fire resistance of masonry walls several new test results have been implemented in EN 1996‐1‐2 for revising the tabulated values. The new tables also provide clearer allocations in terms of minimum thicknesses of walls for fulfilling the conditions regarding the different periods of fire resistance.

Measurements of vibration reduction indices path over junctions AAC/CSU

AbstractIf the sound reduction index of a construction between rooms is to be calculated according to the European standard EN 12354‐1:2017‐11 “Airborne sound insulation between rooms,” the so‐called vibration reduction index is an important input variable, which can be determined both simplified according to Annex E of the standard or via measurements on the basis of EN ISO 10848‐1:2018‐02 and EN ISO 10848‐4:2018‐02. The vibration reduction index factor kij characterizes the transmission of a structure‐borne sound power and results from the direction‐averaged junction velocity level difference at the joint. The length and the equivalent absorption area of the components involved at the joint are standardized and thus made formally applicable for different construction situations. According to EN 12354‐1:2017‐11, in the simplified procedure, the vibration reduction index factor kij, which is determined mathematically via the logarithmic mass ratio of the components or via measurements, is included in the calculation of the flanking sound insulation as follows: urn:x-wiley:25097075:media:cepa2227:cepa2227-math-0001To date, only a few measurements have been carried out in sound laboratories to determine the size of kij. In general, the simplified determination of kij according to Annex E of EN 12354:2017‐11 is used. On behalf of Xella Germany, the Xella Technologie‐ und Forschungsgesellschaft measured the values for kij at a total of 8 joints (so‐called T‐joints). These joints are common component connections between AAC and CSU and occur predominantly at the connection between the load‐bearing exterior wall and a load‐bearing CSU interior wall.The joint insulation dimensions determined by measurement at the T‐joints of CSU and AAC masonry are in part significantly higher than the calculated values determined from the area‐related masses. For the transmission path along the flank (Ff along the walls), the values determined are only slightly above the predicted values at approx. 1–2 dB. On the transmission path from the separating wall to the flank (Df or Fd), the values determined by measurement are in some cases significantly higher (by up to 6 dB) than the values determined by calculation.The flank insulation of AAC is therefore usually underestimated with the simplified method for determining kij.

Robustness evaluation and design of steel and steel‐concrete buildings according to current standards and recent research results

AbstractIn terms of mitigation of progressive collapse, structural robustness is a specific safety consideration, which requires particular attention from all professionals involved in the construction industry, including architects, designers and constructors. The design of buildings considering robustness has evolved considerably over the last two decades, during which different research activities have been developed, leading to new methods and design processes. These practice‐oriented methods and concepts have been recently summarized in a design manual prepared in the framework of the FAILNOMORE RFCS project (grant No 899371), providing to the designer a general design strategy for robustness based on these methods as well as easy to follow worked examples. The proposed design strategy allows to ensure the global stability and the mitigation of progressive collapse of steel and composite structures when subjected to exceptional events, such as vehicle impact, explosion, cascading events involving localized fire or events which are not explicitly specified in the typical structural design process. In this paper, the application of these recommendations is demonstrated by means of realistic worked examples. Typical steel and steel‐concrete composite office buildings, designed according to the current European standards, are evaluated for robustness against identified and unidentified threats. The results obtained with simple and more advanced verification approaches are compared, and possible solutions to improve the robustness of the structures are provided.

Historiographic principles of interaction between civil society and the state

The article analyzes the historiographic principles of interaction between civil society and the state, which is expressed in the dialogue and opposition of public organizations with the state. Various approaches to the definition of civil society, its components and functions, as well as the role of the state in ensuring the development of civil society are considered. The article also includes a historical analysis of the interaction between public organizations and the state on the territory of Ukraine, which provides an opportunity to better understand the current situation in this area. The most important challenges and tasks for the further development of civil society in Ukraine and ways to solve them are outlined. The conclusions of the article may be useful for further research in the field of the theory of the state and law. Also, the nature and ultimate purpose of the existence of civil society is given and revealed in the article. Particular attention is paid to determining the opposition of such a society to the state and its apparatus. Theoretical approaches were also summarized, and the essence of such a society and its functions were determined based on them. The article contains an analysis of the concept of civil society, taking into account the modern interpretation. Some problems of the formation and development of civil society are highlighted through the prism of the necessity of such a society to ensure Ukraine as a democratic, social, legal state. Ways of establishing a civil society in accordance with the assumed duty of the state to citizens regarding the development of the country according to European standards are proposed. The retrospective method, which is used in various sciences such as history, law, psychology, and others, was chosen as the main research method. This method involves the analysis of past events that have occurred in the past in order to understand what causes led to their occurrence, as well as what consequences they had. Key words: state, civil society, civil organizations, self-regulation mechanism, territorial communities.
