Hot Corrosion Behavior of Graded Thermal Barrier Coatings Formed by Plasma Spraying Process
Authors: Mifune N. , Harada Y. , Doi T. , Yamasaki R.
Published: September 2022

Hot corrosion behavior of Thermal Barrier Coatings (TBCs) has been studied by comparison between double layer coatings and graded coatings. Two types of oxide ceramics, 8 mass % Y2O3-ZrO2(8YZ) and 2CaOSiO2-15mass% CaOZrO2 (C2S-15 CZ), with a bond coating of NiCrAlY were applied to metallic substrates in this study. After a hot corrosion test by V2O5-Na2SO4 corrosive ashes, hot corrosion behavior of TBC has been investigated by visual inspection, metallography, X-ray diffraction and EPMA. The C2S-15%CZ coating reacted with V2O5 only where it was in direct contact with the material. The affected area from the reaction was limited to the coating surface where V2O5 existed. The coating showed adequate hot corrosion-resistance. It was found on the 8YZ coating that Y2O3, the stabilizing component, particularly reacts with V2O5 and loses its function; this led to partial spalling of the coating. It was observed that the durability of the double layer TBC was largely influenced by the performance of a corrosion resistant NiCrAlY undercoat which provided protection against corrosive components penetrating through the ceramic topcoat. It was observed that the graded coating degraded due to oxidation of NiCrAlY particles which independently existed near the coating surface and affected the durability of TBC.

Published: September 2022

Quantitative characterization of microstructures of plasma sprayed coatings, that accounts for their anisotropic and “irregular” character, is developed. An important finding is that “islands” of partial contacts along microcrack faces –even if they are very small - produce a strong effect on both elasticity and conductivity, thus reducing the “effective” microcrack density. Theoretical results are twofold: (1) conductive/elastic properties of the coatings in terms of the microstructure, and (2) conductive–elastic cross-property connections, that interrelate the anisotropic overall conductive and elastic constants. They can be utilized for “mapping” possible combinations of the two properties and, thus, for optimization of the microstructure for the combined conductive/elastic performance. Testing of the model against experimental data on YSZ coatings produces a good agreement.

Published: September 2022

In thermal spraying, the knowledge of process basic input parameters and their influence on the final coating properties is crucial. The optimization and reliability of atmospherically sprayed (APS) coatings, especially highly porous thermal barrier coatings (TBC), is closely linked to process understanding. This investigation aims to elucidate the correlation between the basic plasma spraying parameters (like current, plasma gas, stand-off distance, etc.) and the deduced physical dimensions like particle temperatures and velocities and the coating mechanical properties. Within this project, a large range of parameter field was chosen as long as stable plasma working conditions permitted. The influence of preparation on the microstructure analysis and data of mechanical coating measurements are shown.

Published: September 2022

Several studies have been undertaken recently to adapt Yttria Partially Stabilized Zirconia (Y-PSZ) thermal barrier coating (TBC) characteristics during their manufacturing process. Thermal spraying implementing laser irradiation appears as one of these possibilities to modify the coating morphology. This study aims at presenting the results concerning in situ (i.e., simultaneous treatment) and a posteriori (i.e., posttreatment) laser treatments implementing a high power laser diode. In both cases, the coatings were atmospheric plasma sprayed (APS). Laser irradiation was achieved using a 3 kW, average power, laser diode, exhibiting an 848 nm wavelength. Experiments were performed to reach two goals. First, laser post-treatments aimed at building a map of the laser processing parameter effects on the coating microstructure, in order to estimate the laser processing parameters, which seem to be suited to the change into in situ coating remelting. Second, in situ coating remelting aimed at quantifying the involved phenomena. In that case, the coating was treated layer by layer as it was manufactured. The input energy effect was studied by varying the scanning velocity (i.e., between 35 and 60 m.min-1), and consequently the irradiation time (i.e., between 1.8 and 3.1 ms, respectively).

Published: September 2022

Ceramic / plastic composite powder (ceraplas powder) has been produced by Fluidized-bed granulation process (FG process) by varying the binder. Alumina (Al2O3) has been used as ceramics and Polyphenylene-sulfide (PPS) has been used as plastics. PPS has high heat and corrosion-resistant performance. Moreover, sprayed composite coatings have been evaluated by the observation of the coating microstructure, the thermal analysis, the corrosion test and the abrasive wear test. It has been recognized that sprayed composite coatings produced by FG powder have high corrosion-resistance and good wear resistance

Published: September 2022

It is well known that residual stresses in plasma-sprayed coatings play a prominent role on coating-substrate adhesion in particular. This is all the more prominent because the coating is thick and adhesion intricate. The control and measurements of residual stresses in plasma-sprayed coatings onto organic-based substrates result in an issue of very high concern, even though very little (not to say nil) was published in this specific area. In this work, thick coating of a polyurethane resin with Inconel 625 was achieved by plasma spraying coupled with Atmosphere and Temperature Control (ATC), i.e. using cryogenic cooling to limit thermal degradation of the substrate when spraying. Residual stresses were determined by X-ray diffraction at the coating surface due to low X-ray penetration in nickel. In addition, residual stress in-depth profiles were obtained using the incremental hole drilling method. The investigation mainly focused on the measurement of residual stresses. In this paper, residual stresses were studied as a function of plasma spraying conditions. Results are discussed in the light of the coating microstructure. Residual stress measurements resulted in optimizing and controlling coating deformation and adhesion which are crucial for applications.

Published: September 2022

High velocity oxy-fuel (HVOF) sprayed, functionally graded polyimide/WC-Co composite coatings on polymer matrix composites (PMC's) are being investigated for applications in turbine engine technologies. This requires that the polyimide, used as the matrix material, be fully crosslinked during deposition in order to maximize its engineering properties. The rapid heating and cooling nature of the HVOF spray process and the high heat flux through the coating into the substrate typically do not allow sufficient time at temperature for curing of the thermoset. It was hypothesized that external substrate preheating might enhance the deposition behavior and curing reaction during the thermal spraying of polyimide thermosets. An additional difficulty arises from the low thermal conductivity and low specific heat capacity of the PMC substrate, which prevent effective substrate preheating by the HVOF jet as in the case of metallic substrates. A simple analytical process model for the deposition of thermosetting polyimide onto polymer matrix composites by HVOF thermal spray technology has been developed. The model incorporates various heat transfer mechanisms and enables surface temperature profiles of the coating to be simulated, primarily as a function of substrate preheating temperature. Four cases were modeled: (i) no substrate preheating; (ii) substrates electrically preheated from the rear; (iii) substrates preheated by hot air from the front face; and (iv) substrates electrically preheated from the rear and by hot air from the front. Thermal properties of the polyimide needed for the simulations were determined by Differential Scanning Calorimetry (DSC) and Thermo-Gravimetric Analysis (TGA). Microstructural characterization of the coatings and the morphology of polyimide splats sprayed both with and without substrate preheating were analyzed using standard metallographic techniques. Coating temperature in cases (iii) and (iv) never dropped below the crosslinking temperature of the polyimide feedstock. This was the critical condition required for the curing reaction and successful deposition of thermosets by HVOF thermal spraying.

Published: September 2022

A partir da obra de Gilles Deleuze e Félix Guattari, intitulada "O que é a filosofia", propõe-se neste artigo fazer uma reflexão e uma descrição minuciosa na procura de desvendar os pressupostos de Deleuze na trama da arte de conceituar. A partir desses filósofos é possível ter uma atitude diante do pensamento filosófico, problematizar sobre o campo filosófico que nos permeia. Este artigo tem uma abordagem de estudos de natureza bibliográfica, auxiliada pela obra em destaque, bem como de outros autores que se propuseram a fomentar a discussão em torno de tal questão. A Filosofia é um movimento intelectual do pensamento humano, estabelecendo reflexões e arte de conceituar nos pressupostos de Deleuze, e de sabedoria segundo os clássicos filósofos gregos. Entretanto, as inquietações de enveredar  no campo filosófico são complexas, mas refletir faz parte do campo filosófico.

Authors: PASICHNYI VASYL , SHUBINA YEVHENIIA , SVYATNENKO ROMAN , MOROZ OLENA
Published: September 2022

The relevance of this study is conditioned upon the increasing interest in alternative sources of protein, to solve the problem of providing the population with biologically complete food products of a combined composition. The purpose of this study was to investigate the effect of freezing on the stability of the moisture content of semifinished products in the dough covering using several types of meat raw materials, protein, and flour from hemp seed processing products. For the study, eight recipes of minced meat were prepared using beef, pork, red and white meat of broiler chickens with flour and protein from hemp seeds in the amount of 20% to the total mass of minced meat. In the samples, indicators of moisture content, moisture binding, emulsifying ability of products before freezing and after defrosting, and activity of water in defrosted products were determined. In the experimental samples, a substantial difference was found in the stability of the moisture content of semifinished products, depending on the combination of flour and hemp seed protein in the recipes of semifinished products and conventional types of meat raw materials under the influence of freezing. It was found that the best combination of hemp seed flour with beef and pork meat, while protein with broiler chicken meat is the best combination in terms of emulsifying ability. All model samples of minced meat had values above 40%, and all samples, except the combination of hemp protein with pork, were higher than the control. Studies of water activity values in defrosted dumplings were within the normal range of up to 0.970 Aw, and the sample using hemp seed protein and pork had the lowest – at 0.951 Aw. The conducted studies indicate the expediency of selective combination of hemp seed processing products with various types of meat raw materials in the composition of semifinished products in a dough covering. The combination of several types of non-conventional protein-containing raw materials in the composition of frozen semifinished products in the dough covering requires considering their technological compatibility to ensure the possibility of implementing the developed recipes in the production of dumplings in industrial production conditions

Published: September 2022

The relevance of this study is conditioned upon the active introduction of prebiotic preparations into the practice of feeding poultry and the need to determine the impact of their use on quantitative and qualitative indicators of productivity. In this regard, this study is aimed at determining the effect of the introduction of the prebiotic preparation Actigen in the diet of laying hens on their level of productivity and morphological parameters of eggs. Using an integrated approach, the level of egg productivity of chickens was investigated for the introduction of the preparation into the mixed feed in the amount of 500 g/t for 6 weeks. Assessment of poultry at 52 weeks of life indicates a slightly higher level of egg production of chickens of the experimental group – 198.6 pcs against 196.2 pcs in the control group (the difference is 1.22%) and the safety of livestock – 97.50% against 97.00% in the control group. It was found that the mass of eggs obtained from chickens of the experimental group was higher by 1.09 g (p<0.05). A lower level of variation (Cv) of the “egg mass” trait of the poultry of the experimental group (3.05%) than in the control group (3.51%) is positive, and indirectly indicates the level of uniformity of the herd in live weight. It was established that the weight of egg white and yolk of hens in the experimental group was 1.04 g and 0.37 g higher, respectively, than in the control group. The difference between groups is not statistically significant, but it shows the direction of their changes. In the eggs of the experimental group, the large diameter of the egg white was smaller compared to the control group by 1.93%, and the small diameter by 3.56%. The height of the dense layer of white and yolk, which are objective indicators of egg quality, were greater in the experimental group (p<0.001) compared to the control group, which is positive, this difference was 21.54% and 20.00%, respectively. According to the indicators of the energy value of eggs, no substantial differences were found between the experimental groups. The obtained data (increase in the level of egg production of poultry, preservation of livestock, egg weight, improvement of egg quality indicators of chickens of the experimental group) indicate a positive effect of the introduction of the prebiotic preparation Actigen on the level of egg productivity of poultry. The materials of this paper are of practical value for the work of poultry enterprises specialising in the production of food-grade chicken eggs

Published: September 2022

Вступ. Однією з проблем функціону­вання та розвитку портової галузі є низька якість ван­тажно-розвантажувальних робіт, непослі­дов­ність дій щодо збільшення перевантажу­вальних потужностей, що призводить до недобросо­віс­ної конкуренції вітчизняних морських портів. Проблема. Вибір перевантажувальних кон­тейнерних терміналів, на який впливає багато факторів, стає дуже важливим для транс­порт­них компаній. Тому якість перевантажу­валь­них послуг на контейнерних терміналах слід вра­ховувати поряд з факторами, як-от доступ­ність, потужність та інформаційні технології. Метою статті є багатокритеріальна оцінка якості обслуговування перевантажувальних операцій на контейнерних терміналах мор­ських портів України з використанням теорії нечіткої логіки. Методи. У цьому дослідженні викорис­тано метод CFPR (Consistent Fuzzy Preference Rela­tion) – узгоджений нечіткий баланс пе­ре­ваг, який широко застосовується при оцінці якості обслуговування, що характери­зується багатокритеріальною проблемою прий­няття рішень (як кількісних, так і якісних даних). Результати дослідження. За допомогою методу CFPR з використанням реальних даних, а також висновків експертів проведено ком­плексний якісний та кількісний аналіз 5 най­більших перевантажувальних контейнерних терміналів. Результати дослідження показали, що найважливішим фактором є доступність термінала, а найбільшим субфактором – близь­кість до головної магістралі. Висновки. Проведення комплексного якіс­ного та кількісного аналізу допомагає опера­торам контейнерних терміналів краще розу­міти вимоги клієнтів і приймати стратегічні управлінські рішення для підвищення якості їх обслуговування; скоротити витрати та забезпечити кращий сервіс своїм клієнтам; розробити відповідну політику й стратегію для зростання галузі судноплавства.

Authors: ПОЛЮГА Валентина , ЗОЛОТАРЬОВА Оксана , ЖАЛДАК Марина
Published: September 2022

Вступ. Зважаючи на активний розвиток будівельної промисловості, виникає потреба у будівельних матеріалах з певними тепло­ізоляційними властивостями, які потребують використання сучасних в’яжучих із необ­хідним комплексом заданих властивостей. Проблема. Розв’язання проблеми вико­рис­тання вітчизняних зольних мікросфер як наповнювачів будівельних матеріалів має значний науково-практичний інтерес. Метою статтіє оцінка властивостей золь­них мікросфер як товару, що використо­вується для наповнення будівельних матеріалів. Методи. Досліджено зольні мікросфери Курахівської, Придніпровської, Криворізької, Бурштинської та Трипільської ТЕС. Визна­чення складу мікросфер проведено ІЧ-спек­троскопічним аналізом, кристалічної струк­тури – рентгенофазовим,гранулометричного складу – ситовим методом. Результати дослідження. Положення мак­симумів смуг, відповідальних за деформа­ційні коливання зв’язків Si-O зольних мікро­сфер, перебуває в межах 444.1–463.2 см-1.Ці матеріали мають показники інтенсивностей у межах 0.76–1.58. Стосовно енергетичної однорідності зв’язків Si-O мікросфери роз­мі­щуються у міру зменшення: Трипільська > Курахівська > Криворізька ТЕС. Зольні мікро­сфери Бурштинської та Придніпровської ТЕС мають порівняно вищий вміст адсор­бованої води, ніж решта. У складі досліджуваних мікросфер пере­важною є кристалофаза, за винятком Кура­хівської ТЕС, що представлена мулітом. Аналіз гранулометричного складу дослі­джуваних зразків зольних мікросфер пока­зав, що найбільший вміст має фракція 60–200 мкм. Найкрупніша фракція 400–630 мкм взагалі відсутня в усіх досліджуваних зразках. Висновки. Переважними компонентами хімічного складу досліджених зольних мікро­сфер є оксиди кремнію та алюмінію для Трипільської ТЕС, а для Придніпровської – тільки оксиди алюмінію. За ІЧ-спектроскопією визначено, що мікро­сфери Бурштинської та Придніпровської ТЕС мають порівняно вищий вміст води, а при їх використанні як наповнювача для будівельних матеріалів зменшується щіль­ність останніх. За гранулометричним складом зольних мікросфер доведено їхню дрібнодисперс­ність, що значно скорочує фінансові витрати при застосуванні їх як наповнювачів у буді­вельних матеріалах.

Postinfectious coronavirus disease 2019 hemorrhagic cerebellitis: illustrative case
Authors: Chow Eric K. H. , Rabin Barry M. , Ruge John
Published: September 2022

BACKGROUND

Conditions that can mimic posterior fossa tumors are rare. Their identification is crucial to avoid unnecessary surgical intervention, especially when prompt initiation of medical therapy is critical.

OBSERVATIONS

The authors presented a case of pseudotumoral hemorrhagic cerebellitis in a 3-year-old boy who presented initially with headache, persistent vomiting, and decreased level of consciousness 9 weeks after severe acute respiratory syndrome coronavirus 2 infection. Magnetic resonance imaging showed a left cerebellar hemorrhagic mass–like lesion with edema and mild hydrocephalus. The patient responded to high-dose steroids and was discharged 2 weeks later with complete recovery.

LESSONS

When evaluating patients with possible tumor syndromes, it is important to also consider rarer inflammatory syndromes that can masquerade as neoplasms. Postinfectious hemorrhagic cerebellitis is one such syndrome.
The use of an endoscopic endonasal approach for a secondary intraorbital meningioma: illustrative case
Authors: Guedes Breno W. M. , de Souza Júnior Joilson F. , D’Avila Melo Nelson A. , de Menezes Neto João M. B. , Beer-Furlan André , Oliveira Arthur M. P.
Published: September 2022

BACKGROUND

Meningiomas are the most frequent primary tumors in the central nervous system (CNS), but intraorbital location is uncommon and accounts for only 0.2% to 4% of all CNS meningiomas. Lesions in this compartment could be classified as primary, secondary, or ectopic. The close relationship with the optic nerve sheath is a landmark to identify the tumor as primary, whereas secondary tumors commonly come from an extension of an intracranial meningioma, and ectopic meningioma is a concept not yet completely established.

OBSERVATIONS

The authors present a rare case of a secondary intraorbital meningioma operated through an endoscopic endonasal approach. Secondary meningiomas at the medial orbit are very uncommon, given their more common superior and lateral location as an extension of sphenoid meningiomas. The endoscopic endonasal route provides direct access to the medial orbit. The authors present an illustrative case of a meningioma located at the medial orbit and resected through an endoscopic endonasal approach that provided excellent visualization and anatomical exposure. Additionally, the authors review the concept and possible similarities between secondary and ectopic intraorbital meningiomas.

LESSONS

An endoscopic endonasal approach should be considered as a feasible treatment option for intraorbital meningiomas, especially if they are in the medial orbital wall.

Public space has become a relevant factor for cities since it increases people’s quality of life. These areas help reduce physical and mental problems that may arise in society, and in addition, they increase the sense of community and improve the development that children may have. The Covid-19 virus and confinement made this type of space necessary. Although public spaces are taken more into account in the city, they do not take place on the edges of the urban area, as is the case in the community of Paso del Norte in the city of Chihuahua in Mexico. The community has two spaces that can be considered recreation areas, but the reality is that they do not have adequate infrastructure to make them safe and formal places. These make us wonder what the people of this community do in their free time, how they use these public spaces, and how they have evolved over the years. So people in the community were surveyed to solve such unknowns, revealing that these spaces have changed in the last two decades. Especially with the arrival of the Covid-19 pandemic. These green areas added value to the areas where they are, plus many adapted the spaces for recreational, educational, commercial, and productive use. Design is a great tool that can take the detected weaknesses of a community and turn them into strengths to create a good quality public space.
Can I Get There? Can I Play? Can I Stay? Creating an Inclusive Playspace Guide in Australia
Authors: Bringolf Jane , Carnemolla Phillippa
Published: September 2022

Playspaces bring children and adults together for fun and social interaction but are rarely designed for the inclusion of all community members. In Australia, local government authorities (councils) are responsible for parks and playspaces. The New South Wales state government launched their inclusive playspaces policy in 2017. A guideline document was proposed but a guideline does not guarantee implementation. Consequently, an inclusive design process for developing the guide became the strategy. The task was to develop a guide that explained the concepts of inclusion and universal design within the playspace context. The project took an iterative and collaborative approach to the design of the guide. Intended users were those involved in creating playspaces, not playspace users per se. The participatory governance structure involved three levels of collaboration: a small steering group of experts, a larger group with key stakeholders, and a wider group of stakeholders and interested persons. This collegial and participative process consisted of a series of meetings and workshops which fostered learning and ideation for all participants. Through this process three underpinning concepts emerged: Can I get there? Can I play? Can I stay? The process educated and informed stakeholders, encouraged participants to contribute to the outcomes and provided community-led guidance for those contracted to design the guideline. The result was an inclusive playspace guide that recognized the design guidance required by council personnel in the context of universal design. The process and governance structure provides a good working model to build on. The success of the guideline was recognized with a national award from the Institute of Landscape Architects for Community Contribution. The purpose of this paper is not to comment on or evaluate the outcome of the guidelines. Rather, it is to document the inclusive and participatory governance structure and iterative process from a professional participant perspective.
Policies and Processes for Accessibility from a UD Perspective: The Integrated Approach Supported by the Friuli Venezia Giulia Region (IT)
Authors: Burelli Amanda , Simone Consuelo
Published: September 2022

With Regional Law no. 10 of 19 March 2018 (General principles and implementing provisions on accessibility), the Autonomous Region of Friuli Venezia Giulia has set itself the objective of improving urban accessibility throughout the regional territory, in order to guarantee equal conditions for everyone to enjoy open spaces and the built environment. The improvement of accessibility is conceived as a long-term objective, to be implemented in stages, according to an incremental development project model. Still today, when work is carried out to eliminate architectural barriers, designers adopt an approach that looks at the “barrier/disability” binomial, identifying “dedicated” solutions and tackling the problem of accessibility in relation to specific targets of users whose ability to access and use spaces and environments is assessed in relation to the capability of a person generically defined as “normally able”. In contrast, in a barrier-free approach, designers are called upon to adopt a broader perspective, to look at the variety of people who make up a real community (extended user base), and to consider different physical conditions, ages, abilities and capacities (motor, sensory and cognitive), from the early stages of the project. In order to promote change and to impart this change of approach, the Autonomous Region of Friuli Venezia Giulia has envisaged integrated actions, aimed, as a whole, at accompanying the process that guides the project culture towards a progressive adherence to the methodological criteria of Universal Design, introducing, at the same time, support measures aimed at financing the Municipalities of the Region both for the preparation of barrier elimination plans (PEBAs) and the implementation of the interventions identified in those plans. Among the envisaged actions, the most important is a general accessibility mapping, which includes the adoption of a terminology system (accessibility ontology) integrated in a specific computer application, through which the municipalities will be able to detect architectural barriers, in a homogeneous way, over the entire regional territory.
Interpreting Inclusion for Sanitation Perspectives from India: A Contextual Approach to Universal Design
Authors: Purkayastha Divyang , Raheja Gaurav
Published: September 2022

Access to water, sanitation, and hygiene (WASH) for all is fundamental for sustenance. Goal 6 of the UN’s Sustainable Development Goals urges that ’universal access to drinking water, sanitation and hygiene’ is fundamental as a response in the current post-COVID scenario. Despite Government of India’s efforts through programs like Swachh Bharat (Clean India) Mission, there is a long way to go to integrate equity and inclusion in the sanitation facilities of the public realm. This paper is an attempt to understand the aspect of inclusion in sanitation systems of urban public spaces of India, limiting the study to Delhi and Noida, which are in the National Capital Region (NCR). The aim is to explore the contextual challenges of universal design in public sanitation and develop an understanding of what makes a public toilet inclusive in the urban Indian context. A field-based, mixed methods approach is followed which begins with a literature review of government policies & schemes and theoretical understanding of inclusion as well as the role of universal design as an approach to achieve inclusion. This is followed by on-ground studies involving ethnographic surveys, analysis of imagery and field observations. The results show an analysis of the inclusive aspects of sanitation under the thematic domains of public perception, usage preferences and issues in the public toilet experience. The sanitation facilities in urban public spaces are used by a diverse population and the results showcase a collection of the qualitative experiences of a varied set of user groups. The subjective challenges of inclusive sanitation are highlighted through the various stages and components of the entire sanitation system – the design & infrastructure, operations & maintenance, and behavioural patterns. This paper tries to raise new grounded questions to further explore the highlighted marginal distinctions between inclusion and accessibility in the urban public sanitation experience of India.
Home-Based Primary Care: Adaptability Criteria for the Bedroom Layout and the Furnitures/Technological Equipments
Authors: Cellucci Cristiana
Published: September 2022

Within the past decade, advances in medical technology, the desires and complex care needs of an ageing population, and innovative care delivery models have initiated a shift from providing care in hospitals to outpatient settings. And more recently, the acceleration and amplification of these factors is pushing healthcare options even further from the traditional inpatient and outpatient settings towards acute and subacute care in the home. This has led the medical community to look toward providing more tools and methods of care that patients can access safely right from home and the designers to think as the homes of the future will be flexible to support both an array of devices to provide a healthcare delivery and the humanization and personalization of the domestic space. The paper identifies criteria for the flexible design of the physical environment (including the home, equipment, furniture, etc.) that support and facilitate safety, comfort, and healing, in relation to the various patient populations, at their own physical and psychosocial needs, at the range of equipment/technology (from chronic to acute care), at the caregiving and daily living activities.
A Pattern Language for Inclusive Design: A Set of Patterns for Designing Reusable Accessible Solutions
Authors: Valtolina Stefano , Sisto Alessandro Vivian
Published: September 2022

A common cause for inconsistent accessibility in the design of ICT applications is that designers work to develop optimal and satisfactory interfaces but they do not take care to comply with all users’ needs and possibilities to access. The study presented in this paper stems from a lack of published evidence able to support designs in developing accessible interfaces for websites, mobile apps or conversational Interfaces (chatbot or voicebot). This work aims at investigating accessible design patterns that can be used by designers to implement applications accessible by multiple devices. To solve this problem, we propose a design pattern language able to provide WCAG compliant design out-of-the-box solutions. The navigation through the design patterns allows designers to gather existing solutions based on solid evidence and examples to develop inclusive applications accessible by web, mobile devices or conversational agents.
NEAR PROJECT – Accessibility Plan for the Monumental Complex of the Opera di S. Maria del Fiore in Florence. Accessibility as an Element of Social
Authors: Vessella Luigi
Published: September 2022

Italy is the country with the highest number of sites recognised as World Heritage by UNESCO and one of the nations with the highest density of sites of cultural interest both in Europe and in the world. Unfortunately, only a small part of these are completely and easily accessible, and certain of the most fragile sections of society, for example disabled persons, are in fact excluded from the possibility of visiting and discovering the said places. The research presented here represents an “experiment” in the application of the methodology of the Accessibility Plan to the monumental complex of the Opera di Santa Maria del Fiore in Florence, in other words the attempt to increase the degree of accessibility of the complex through a medium and long-term innovative strategic planning tool that takes into consideration not only material aspects (physical and sensory accessibility) but also aspects of an intangible nature, thus making it possible for people to fully understand the cultural meanings of the places, and focusing on the “experiential dimension of the visit” [1].
