Range Expansion and First Observation of Tridacna noae in American Sāmoa
Authors: Marra-Biggs Paolo , Fatherree James , Green Alison , Toonen Rob
Published: May 2022

Giant clams are keystone species on coral reefs, but global demand for
their harvest has decimated populations and resulted in all Tridacnids
being listed on both CITES and IUCN lists. However, giant clams are
notoriously difficult to identify, and recent molecular work has
revealed that morphological misidentification of giant clams have
confounded current population assessments and extinction risk. The most
recent study of the status of giant clams in the Samoan Archipelago was
published over 20 years ago, without molecular corroboration of visual
identifications. Using morphologic characteristics and ez-RAD genetic
techniques, we identify the existence of Tridacna noae in the Samoan
archipelago, presenting the first observation and a resulting range
expansion. Accurately identifying the extant species in the archipelago
is the first step towards a much-needed population status assessment to
effectively manage these long-lived species.

Published: May 2022

To improve sresponse performance of the magnetically suspended
gimballing flywheel in wide frequency range, a spherical magnetic
bearing with dual-winding structure is proposed. Working principle of
dual-winding structure is introduced, and electromagnetic
characteristics of the rotor in wideband range are analyzed by using
equivalent magnetic circuit method and finite element simulation method.
Simulation errors of the maximum electromagnetic force under
low-frequency and high-frequency suspension are only 0.085 and 0.054
respectively. Experimental results show that the response time of the
rotor from low frequency to high frequency is only 40ms. Simulation and
experimental results is much better than those of the single winding
structure.

Authors: Hashmi Dr Kiran , Fayyaz Humera Naz
Published: May 2022

This paper addresses an investigation into the relationship between adolescence and academic well-being. It explores teachers, parents, and students’ perceptions on adolescents’ understanding about emotions and academic development. In adolescence, the students are engaged in both incidental and formal learning, they learn new experiences, and strives to become independent, self-reliant, and confident.  Adolescents prefers to talk more about themselves, their lives, their decisions, their thinking and their ways of approaching solutions.  At this stage, adolescents may get hurt easily, which may lead to dissatisfaction or develop adverse behaviors. These emotional disorders or behaviours need immediate identification by parents, teachers and peers to avoid an effect on their academic performance. Using phenomenological research approach, the study gathered perceptions of teachers, parents and students through three focused group discussions. The data were analysed through thematic analysis techniques. The findings show that there is a relationship between adolescents’ emotions and their academic wellbeing.

Authors: Kalajžić Vesna , Ražnjević Zdrilić Marijana , Jontes Dejan
Published: May 2022

The phenomenon of global warming and its consequences are challenges we face in modern society. In addition to these issues, the paper is motivated by media reports on the 2019 worldwide climate strikes and the UN Climate Action Summit, held in New York in September of the same year. Swedish climate activist Greta Thunberg, whose performance at the Summit sparked a lot of interest in the media worldwide, found herself in the centre of media attention. The goal of this paper is to explore the image of climate change presented on Croatian and Slovenian online portals, which were selected based on their readership (tracked using Alexa.com). These included Croatian online portals: 24sata.hr, Index.hr, Net.hr, Narod.hr, Vecernji.hr. Net.hr, and Slovenian online portals: 24ur.com, nova 24TV, SIOL.net, Slovenske novice, Svet24, TV SLO. The paper applies the method of qualitative and quantitative content analysis. The research corpus consisted of 194 articles published in Croatian and Slovenian online media (136 and 58 respectively). The research focuses on the scope of reporting on climate change, identification of the main topics and attitudes, and the question of celebritization of the issue itself. Research results showed that there are significant differences when it comes to the framing of climate change issues, particularly Greta Thunberg’s activism, in Croatian and Slovenian online media.
Anthropogenic ecosystem of green roofs from the perspective of rainwater management
Authors: Agnieszka Boas Berg  , Erika Hurajová  , Martin Černý  , Jan Winkler
Published: May 2022

In Bielsko-Biała (Poland), thanks to the initiative of the originator and architect, a green intensive roof was created on a shopping centre. This roof primarily serves as a garden that enhances the qualities of the residential area, but also as a means of absorbing some rainwater and slowing down the runoff. The water collects in the rainwater retention tank located under the building. Rainwater also evaporates, and its surface runoff is slowed down as it passes through the vegetation on the green intensive roof. This paper addresses some of the operational problems of a selected green roof. The Water Law introduces the obligation to pay chargesfor the reduction of natural terrain retention. Shopping centres usually occupy large areas of land, but their roofs are rarely used for rainwater management and the installation of biologically active surfaces. Green roofs undoubted advantage is the increase of biologically active surface in urban areas. It is also an oxygen--producing surface as well as reducing urban heat islands and attractive place for honeybees and butterflies. The roof in question meets the requirements of a retention facility mentioned in the Water Law Act. It isa multifunctional system for rainwater management. The analysis suggests that the roof under study is nota self-sustaining ecosystem and requires human intervention.
Clayey sand–nonwoven geotextile interface characterisation through gradient ratio test
Authors: Anna Markiewicz
Published: May 2022

Nonwoven geotextiles have been widely used as a substitute for mineral materials to provide filtration functions in civil engineering. However, in filter systems, geotextiles are the first to be in contact with soft, saturated, and fine soils. For that reason, the selection of a geotextile filter depends on the characteristics of the geosynthetics and the base soil (e.g. grain size distribution, internal stability, permeability) and on the design and boundary conditions such as continuity of the soil–geotextile filter contact interface. The geotextile filter must be properly designed to avoid clogging. The most commonly method used for measuring filtration compatibility of soil–geotextile systems is the gradient ratio test. This paper presents the gradient ratio test program for needle-punched nonwoven geotextile used as a filter layer and internally unstable soil. Laboratory tests were conducted in a modified gradient ratio test apparatus. Test results show that gradient ratio increases with time due to clogging. Also the need for a measurement of water heads very close to the geotextile to measurement of water heads very close to the geotextile to provide additional information on the soil–geotextile system behaviour were presented.

Authors: Mohd Rusdi , Isa Siti Suzilliana Putri Mohamed , Arifin Norihan , Bachok Norfifah
Published: May 2022

The thermal properties of radiating water-based hybrid nanofluid with nanoparticles Cu-Al2O3 over an inclined shrinking plane are investigated. The govern?ing equations in this model are transformed into similarity equations. Then, the boundary value problem solver (bvp4c) in MATLAB software is used numerically to solve these similarity equations. It has been discovered that utilizing MATLAB software the dual numerical solution occurs for certain values of the nanoparticle volume fraction and the suction parameter. Therefore, the skin friction coefficient and Nusselt number increase due to the effect of radiation and suction parameter. As a result of the findings, we were able to identify that the increasing nanoparticle volume fraction and the suction parameter cause the reliable numerical findings for velocity profile to enhance. When the first solution of suction parameter is increased, the skin friction coefficient and the local Nusselt number increase. Meanwhile, in the presence of the radiation parameter, the temperature of both solutions rises.
Coupling selective catalytic reduction process inside a coke oven regenerator: The influence of mixing parameters on NO reduction
Authors: Bai Wei , Feng Jun-Xiao , Zhao Yu-Jie , Fan Huan-Bao
Published: May 2022

Many coking plants have adopted the process of preheating flue gas to apply medium and low temperature selective catalytic reduction (SCR) denitrification technology, which increases the NOx treatment cost, fuel consumption, and generates secondary pollutants. Based on the unique temperature distribution characteristics of the coke oven regenerator, this work proposes a method for synergizing SCR inside the regenerator to remove NOx. A 3-D numerical model of the synergy between heat storage and SCR reaction was constructed to study the influence of mixing parameters (atomization angle, injection velocity, nozzles number) on the NO reduction and NH3 distribution. The validity of the model was verified. The results showed that the uneven distribution of NH3 near the catalytic layer and the small SCR coating area limited the NO reduction efficiency. Increasing the number of nozzles was more beneficial than the injection velocity and atomization angle for improving the NH3 distribution uniformity and NO reduction efficiency, achieving a maximum NO reduction efficiency of 37.1% (reduced to 251.6 mg/m3). Further research found that the NO reduction capacity of the co-operative SCR model cannot exceed 36% without changing the thermal storage brick structure. When the inlet NO concentration is less than 235 mg/m3, the reaction model ensures that the outlet NO concentration meets the national emission standards.
Numerical study on Nusselt number of moving phase interface during wax melting in tube using lattice Boltzman method
Authors: Zhou Zheng , Liu Xiao-Yan , Li Xiao-Qing , Xu Ying , Wang Zhi-Zhuang
Published: May 2022

Paraffin melting is widely applied to the fields of PCM energy storage, gathering and transportation pipe-line paraffin removal, etc. Natural-convection is the main heat transfer mode during paraffin melting, and Rayleigh number is an important factor affecting the change of natural-convection intensity. Nusselt number variation can reflect the influence of natural-convection on heat transfer. The conventional Nusselt number of hot wall surface reflects only the convective heat transfer intensity of the fixed wall, while it does not take into account that the phase change interface has the characteristics of moving in the phase change process. A double distribution model of paraffin phase transformation in circular tube based on lattice Boltzmann method is established in this paper. The influence of Rayleigh number on the temperature field and flow field of wax in circular tube is analyzed. The heat transfer process is reflected by Nusselt number of moving phase interface. The relation between Nusselt number of moving interface and Nusselt number of hot wall surface is also presented. The results show that the Nusselt number of moving phase interface can reflect the complex non-linear characteristics of natural-convection and describe the phase change heat transfer process of wax more accurately. Calculation formula of Nusselt number of moving phase interface and hot wall during wax phase change is proposed. Increasing Rayleigh number can quicken the melting of wax to meet the actual engineering requirements.
Heat transfer enhancement by sinusoidal wavy tape insert in two-pass ribbed channels
Authors: Jiang Wei , Mei Ziyue , Wu Fan , Hou Youmin , Xie Danmei
Published: May 2022

The turbine inlet temperature is one of the most critical parameter that determines the thermal efficiency and thrust-weight ratio of the gas turbine. However, the higher gas turbine inlet temperature significantly increases the thermal stress on the blade, which necessitates effective cooling strategy to reduce the blade temperature. In this study, a united blade cooling strategy was developed by adopting a two-pass ribbed cooling channel with wavy tape for the reason that ribs are near-wall turbulence promoters while the wavy tape is core-region promoter with relatively lower pressure-drop penalty. Ribs and wavy tape may complement each other in the cooling channel. The synergistic effect of the combined near-wall and core-region heat transfer promoter was numerically studied for Reynolds numbers from 6000 to 30000. Two key geometrical factors, namely rib to wave crest phase shift and relative wave amplitude, have significant effect on the thermal performance. The results demonstrate that wavy tape with different phase shift configurations can eliminate the lower heat transfer areas and produce more uniform heat transfer. The 0? phase shift achieved best overall thermal performance, which provided 1.07-1.08 times the flat tape heat transfer enhancement with 1.09-1.11 times the pressure drop penalty. The better heat performance is due to the secondary flow induced by wavy tape, which enhances the fluid mixing between near-wall and core-region.
HIF-2α Preserves Mitochondrial Activity And Glucose Sensing in Compensating Beta Cells in Obesity
Authors: Moon Jae-Su , Riopel Matthew , Seo Jong Bae , Herrero-Aguayo Vicente , Isaac Roi , Lee Yun Sok
Published: May 2022

In obesity, increased mitochondrial metabolism with the accumulation of oxidative stress leads to mitochondrial damage and beta cell dysfunction. In particular, beta cells express anti-oxidant enzymes at relatively low levels and are highly vulnerable to oxidative stress. Early in the development of obesity, beta cells exhibit increased GSIS, in order to compensate for insulin resistance. This increase in beta cell function under the condition of enhanced metabolic stress suggests that beta cells possess a defense mechanism(s) against increased oxidative damage, which may become insufficient or decline at the onset of type 2 diabetes. Here, we show that metabolic stress induces beta cell HIF-2a, which stimulates anti-oxidant gene expression (e.g. Sod2 and Cat) and protects against mitochondrial ROS and subsequent mitochondrial damage. Knockdown of HIF-2a in Min6 cells exaggerated chronic high glucose-induced mitochondrial damage and beta cell dysfunction by increasing mitochondrial ROS levels. Moreover, inducible beta cell HIF-2a KO mice developed more severe beta cell dysfunction and glucose intolerance on high fat diet, along with increased ROS levels and decreased islet mitochondrial mass. Our results provide a previously unknown mechanism for how beta cell defends against increased metabolic stress to promote beta cell compensation in obesity.

Published: May 2022

Objective: Patients with diabetes have an increased risk for lower-limb amputation (LLA) but biomarkers to assess risk of LLA are lacking. Adrenomedullin (ADM) is a vasodilator peptide that also plays a role on fluid and electrolyte homeostasis in the kidney, increasing natriuresis and diuresis. ADM was shown to be associated with cardiovascular and renal events in diabetes, but it was not investigated in terms of LLA risk. We investigated the hypothesis that ADM is associated with LLA in people with type 2 diabetes.

Research Design and Methods: We studied 4375 participants of DIABHYCAR and SURDIAGENE cohorts (men 68%, mean age 66 years, mean duration of diabetes 12 years, median follow-up 5.3 years). Plasma MR-proADM (a surrogate for ADM) was measured by immunofluorescence. Five SNPs in the ADM gene region were genotyped.

Results: LLA requirement during follow-up by increasing tertiles of plasma MR-proADM distribution was 1.0% (T1), 2.3% (T2) and 4.4% (T3) (p<0.0001). In Cox multivariate analysis, adjusted hazard ratio (95%CI) for LLA was 4.40 (2.30–8.88; p<0.0001) for T3 vs. T1. Moreover, MR-proADM significantly improved indices for risk stratification of LLA. Four SNPs were associated with plasma MR-proADM concentration at baseline and with LLA during follow-up. Alleles associated with higher MR-proADM were associated with increased LLA risk.

Conclusions: We observed associations of plasma MR-proADM with LLA and of ADM SNPs with plasma MR-proADM and with LLA in people with type 2 diabetes. This pattern of Mendelian randomization supports the causality of the association of ADM with LLA.

Published: May 2022

Objective: To synthesize available evidence from case reports regarding the efficacy of knee–ankle–foot orthosis (KAFO) on functional mobility and activities of daily living (ADL) in patients with stroke. Methods: The following databases were searched, based on the Population Intervention Comparison Outcome (PICO) model: PubMed, CINAHL, Sco- pus, Cochrane Central Register of Controlled Trials, PEDro, Web of Science, and Igaku Chuo Zassi (in Japanese). Methodological quality was assessed using the CARE checklist.Results: A total of 14 articles, including 15 cases, were selected. Clinically meaningful improvement in functional mobility was reported in 10 of 15 cases, measured using the Functional Ambulatory Category, Trunk Control Test, walking speed, and Berg Balance Scale. Clinically meaningful improvement in ADL was reported in 9 of 15 cases, measured using the Barthel Index and Functional Independent Measure. However, the methodological quality of the reviewed articles was low, with missing information on limitations of management, adverse events, and patient-reported outcomes.Conclusion: This systematic review of case reports found a low level of evidence of the efficacy of KAFO in terms of improvement in functional mobility and ADL. Of value, this study revealed the optimal outcomes for measuring the efficacy of KAFO.
LAY ABSTRACTFor many years, rehabilitation experts have considered knee–ankle–foot orthosis (KAFO) therapy to be effective for patients with stroke. However, evidence regarding the efficacy of KAFO is unclear, since there is a lack of published high-quality studies. Recently, some case reports have been published claiming the efficacy of KAFO therapy. A systematic review was performed, which reviewed 14 case reports involving 15 patients. Improvements of functional mobility and activities of daily living were shown in 10 and 9 of the 15 patients, respectively. However, the methodological quality of the reviewed case reports was low. These findings present the current evidence from case reports regarding KAFO therapy in patients with stroke; however, the findings are insufficient to draw clear conclusions about the efficacy of such therapy. Of value, the study revealed the optimal outcome measures for use in measuring the effect of KAFO therapy, which can be used to facilitate high-quality future studies.

Published: May 2022

Aim

The study evaluated the efficacy and potential erosion of non-peroxide strips compared to hydrogen peroxide (HP) whitening strips (WSs).

Methods

Color evaluation samples (N=64) were distributed into four groups and treated according to manufacturer’s directions. NC: Negative control treated with water; BT: Non-peroxide Brilliant Dissolving Strips; FM: Non-peroxide Fancymay Teeth WSs; WS: Crest 3D Brilliance HP White Strips. A contact-type spectrophotometer was used to measure color at baseline (T1), 1-day posttreatment (T2), and 1-week posttreatment (T3). Teeth were cut to a rectangular block for micro-CT erosion assessment. The samples (N=30) were divided into five groups. In addition to the four groups for color assessment, a positive control (PC) treated with 0.25% citric acid was added. The samples were scanned, reconstructed, and measured for erosion depth using a micro-CT analysis program software. Kruskal-Wallis test was used to determine differences in color change and erosion depth among the groups. Tests of hypotheses were two-sided with an alpha level of 0.05.

Results

The mean ΔE*ab at 1-day/1-week posttreatment were 2.4/2.5, 2.8/2.9, 2.8/3.2, and 8.6/11.0 for NC, BT, FM, and WS, respectively. There was a statistically significant difference for ΔE*ab at 1-day and 1-week posttreatment (p<0.001). Group WS had the highest color change, while the other three groups did not differ from each other (p>0.05). Mean erosion depths in microns were 0.52, 0.58, 0.42, 0.49, and 29.55 for NC, BT, FM, WS, and PC, respectively. There was a statistically significant difference among the groups (p=0.004). Group PC had the greatest erosion, while the other groups had negligible erosion that did not differ from each other (p>0.05).

Conclusion

Peroxide WSs had superior whitening efficacy compared to non-peroxide strips. None of the tested products compromised tooth structure integrity through enamel erosion.

Published: May 2022

The aim of this study was to evaluate the masking ability of a combined application of opaquers and resin composite over discolored backgrounds: A3, A3.5, C2, C3, and C4.

The groups were divided according to the opaquer brand, the number of opaquer coats (one or two), and the thickness of the resin composite layer (0.5 or 1.0 mm). The color measurements were made by a reflectance spectrophotometer (SP60, EX-Rite). The color difference between the opaquer + resin composite + background and a reference background was calculated using the CIEDE2000 formula. ANOVA and Tukey’s post hoc test (α=0.05) were used to analyze the ΔE00 mean values. A bivariate analysis was used to determine the association between dependent and independent variables. The masking ability was rated by the ΔE00 visual thresholds of acceptability and perceptibility (Excellent Match: ΔE00 ≤ 0.8; Acceptable Match: 0.8 < ΔE00 ≤1.8; Moderately Unacceptable Mismatch: 1.8 < ΔE00 ≤ 3.6; Clearly Unacceptable Mismatch: 3.6 < ΔE00 ≤ 5.4; Extremely Unacceptable Mismatch: ΔE00 > 5.4).

The mean ΔE00 values ranged from 0.5 to 5.52. Masking ability was affected by the opaquer brand, thickness of the resin composite layer, and background shades. Most of the combinations that achieved either excellent or acceptable masking ability were obtained with combinations composed of one or two coats of opaquer and a 1.0-mm-thick resin composite layer for all backgrounds except C4. Acceptable results were also obtained for combinations with 0.5-mm-thick resin composite over C2, A3, and A3.5 backgrounds.

Published: May 2022

Shallot cultivation in Lampung faces challenges because the land is dominated by ultisol soils, which have low nutrients. Therefore, soil improvement materials such as biochar and fertilizers are needed. This study aims to determine the effect of coconut shell biochar addition on the effectiveness of NPK fertilizer in the production of shallots. The study was arranged in a Factorial Completely Randomized Design consisting of 2 factors, namely the dose of biochar (0, 40, 80, and 120 g/pot) and the dose of NPK fertilizer (0, 0,8, 1,6, and 2,4 g/pot). Each treatment combination was repeated 3 times. Parameters included soil characteristics (pH, soil volume shrinkage) and plant parameters (plant height, number of leaves, canopy area, buld number and diameter, evapotranspiration, fresh root weight, bulb air dry weight, and water productivity. The results showed that coconut shell biochar had a significant effect (α = 0.05) in increasing soil pH and decreasing soil shrinkage. The dose of biochar 80 g/pot (B2) with a dose of NPK 1.6 g/pot (N3) was the best treatment. In this treatment combination, shallots produced an average weight of 120.54 g/pot of fresh stover, 14 bulbs with diameter of 2.05 cm and air dry bulb weight of 70.17 g/pot, and the water productivity of 18.22 kg/m3. Keyword: Canopy area, Fertilizer dose, pH, Soil shrinkage, Water productivity

Published: May 2022

The purpose of this study was to observe the effect of extreme rainfall patterns in the DI Yogyakarta region on the growths of rawit/cayenne (Capsicum frutescens L.) and keriting/curly (Capsicum annum) chili peppers. The experimental design used was Randomized Complete Block Design (RCBD) with single factor consisting of three levels namely: maximum frequency index (P1), rainfall intensity index (P2), and control treatment (K).  The frequency and intensity indexes (P1 and P2) of May-June-July from each weather station were used as the bases of rainfall simulations applied in watering the rawit and keriting chili pepper cultivations. Whilst, control (K) was the watering on the basis of optimum crop water requirement. The growth parameters observed included plant height, number of leaves, age of flowering, age of fruiting, age of first harvest, final weight of biomass, and yield. The data sets were analyzed by using one-way Analysis of Variance (ANOVA) at α=0.05 for each species. The results showed that the three levels of treatments did not significantly affect the growth and yield based on all parameters observed for both of the two species. So even the potted media were flooded, the water easily drained through the holed base of pots, making plant growth undisturbed. This finding suggested that planting chili peppers in pots or elevated media could mitigate the effect of extreme rainfalls.Keywords: Extreme Precipitation, Extreme Indices, Plant Growth, chili pepper

O artigo apresenta o resultado de uma análise documental efetuada a 406 planificações da prática educativa de monitores de nove escolinhas de gestão comunitária da província de Niassa, em Moçambique. Estas escolinhas comunitárias constituem uma resposta educativa a crianças até aos 6 anos e enquadram-se num projeto desenvolvido pela Diocese de Lichinga que, com a parceria e apoio de outras organizações não governamentais, ao longo de mais de 20 anos, tem tido como intuito reforçar a oferta e a melhoria da qualidade do trabalho na área da educação pré-escolar. Esta análise permitiu caracterizar o modo de planificar dos monitores responsáveis pela prática educativa das escolinhas comunitárias, identificando aspetos formais e pedagógicos, nomeadamente no que diz respeito às intencionalidades, aos conteúdos, às atividades e experiências educativas que proporcionam, à organização do espaço e do tempo, ao papel destinado à criança nestes processos e à reflexão e avaliação sobre a intervenção. Os dados foram reveladores do trabalho de formação já realizado junto destes monitores permitindo equacionar melhorias ao nível da formação e intervenção destes profissionais, nomeadamente no que diz respeito à necessidade de assumirem, cada vez mais, uma atitude construtora do currículo.
Primer proyecto español de marca-país: la Exposición Iberoamericana de Sevilla, 1929
Authors: Martín Emparán Ainhoa
Published: May 2022

Los carteles y la información gráfica que se utilizaron para promocionar la Exposición Iberoamericana de Sevilla y la Exposición Universal de Barcelona de 1929 representan históricamente el primer plan estratégico de comunicación en el que un gobierno español intentó crear, aunque todavía de forma rudimentaria, lo que hoy en día se define como estrategia de "marca-país". A pesar de tener lugar en un contexto oficial muy conservador, el control no era estricto en el campo del diseño gráfico; Así, coexistían exposiciones muy tradicionales con expresiones de gran modernidad estética.
Codificación y decodificación visual de la letra en el Sistema de Identidad Corporativa
Authors: Raposo Daniel
Published: May 2022

Este artículo trata del recurso estratégico de los tipos como signos de la Identidad Visual Corporativa y, por tanto, como actores que intervienen en el fenómeno de la marca. Un tipo es un signo creado por la actividad humana y, al mismo tiempo, también puede ser un elemento estratégico que favorezca la Identidad Visual Corporativa. Este artículo forma parte de una tesis doctoral en curso sobre diseño que tiene por objeto explorar la capacidad de significación de los tipos como elemento del sistema de identidad visual corporativa.
Conectar ideas
Authors: Lopez Marín Enrique
Published: May 2022

Dos formas de entender la práctica del Diseño, su origen y justificación histórica. La metodología en el proceso de trabajo del Diseño. El talento, la intuición y la creatividad frente al método y el sistema. El Diseño como "práctica de resolución de problemas" y el Diseño como "práctica artística". La Escuela de Ulm y la etapa "postmoderna" del Diseño. Lo útil y funcional en la Modernidad frente a los valores emocionales en los productos. El descrédito de la autoría en las artes, en la literatura. La búsqueda de lo vernáculo y autóctono en una sociedad globalizada. La demanda de "creatividad" anónima como recurso comercial. El exceso de especialización frente al "saber ver" para entender.

Velocità, pasión por el diseño del automóvil en el Centenario del Futurismo
Authors: García Garrido Sebastián
Published: May 2022

La velocidad es la cualidad más destacada de los automóviles, aunque sería el Movimiento Futurista (Marinetti, Milán 1909) el que inicialmente definiera y promover esta pasión por la velocidad: "el esplendor del mundo ha aumentado sustancialmente con un nuevo tipo de belleza: la pasión por la velocidad...". Estas palabras establecen el ideal del diseño italiano según el cual "un diseño bello se convierte al mismo tiempo en el más competitivo funcionalmente". La propia fábrica de FIAT (1923) se proyectó como una inmensa máquina de producir coches, y el edificio de Lingotto ha seguido siendo el icono de los futuristas desde entonces.
Design e territorio. Cuando l’oggetto progettuale del design e ’il capitale territoriale
Authors: Villari Beatrice
Published: May 2022

Partendo dal presupposto che il Design può contribuire al processo di sviluppo territoriale, i designer dovrebbero prendere in considerazione i fattori che definiscono sia il territorio che la pratica del design. L'ipotesi è che certe condizioni legate alla società in cui operiamo (società della conoscenza o società della rete) possono influenzare la qualità dei territori e quindi la natura della pratica del design. Dal punto di vista del design, queste condizioni possono influenzare la scelta della disciplina, così come gli approcci e gli strumenti che potrebbero essere applicati. L'autore delineerà un approccio progettuale per lo sviluppo locale che impiega concetti chiave (come reti, asset intangibili, condivisione della conoscenza) e che lavora a diverse scale di progetto: prodotto-servizio, comunicazione e visione strategica.
Desarrollo metodológico del Diseño en la cultura latina. Carta de Turín 2008
Authors: García Garrido Sebastián
Published: May 2022

El escenario y la ocasión de la celebración de la primera capital mundial del diseño ha sido el catalizador de una valiosa iniciativa de su promotor, el profesor Flaviano Celaschi, en el Politécnico de Turín en comisión de servicio desde su puesto en la Facultad de Diseño de Milán. Se trata de un destacado impulsor de lo que se entiende en Italia como Metaproyecto —una investigación rigurosa, multidisciplinar y pormenorizada que garantice la eficacia de los resultados— y de su orientación hacia sectores no materiales, como el ámbito de los Bienes Culturales y la valoración de cualquier tipo de referente o interés que lo demande.
Letras Latinas. Tipos Latinos
Authors: Balius Andreu
Published: May 2022

América Latina está viviendo un momento de enorme vitalidad en lo que refiere al diseño de tipografía. Un fenómeno totalmente nuevo y que recuerda lo vivido en España a comienzos de los años noventa. A diferencia de aquellos tempranos momentos en que la tecnología digital se encontraba en un estadio muy primario, los diseñadores latinoamericanos han sabido tomar con fuerza el avance de la tecnología y aplicarlo al diseño de tipografía. Prueba de ello es la calidad del material expuesto en la muestra Tipos Latinos que se pudo disfrutar durante los días en que tuvo lugar el Tercer Congreso de Tipografía, en Valencia.
Reseña de "De lo bello de las cosas. Materiales para una estética del diseño"
Authors: Rodríguez Ortega Nuria
Published: May 2022

Si entendemos por Estética la reflexión sobre lo bello, hablar de lo bello de las cosas es hablar de la dimensión estética de ese mundo objetual que nos rodea, en el que funcionalidad, emotividad, simbolismo, significatividad y forma se hibridan. La reflexión sobre lo bello de las cosas es también una reflexión sobre la dimensión estética del diseño, entendido éste como la praxis conformadora de los objetos.

Revisión de" La idea y la materia"
Authors: Ríos Moyano Sonia
Published: May 2022

Según puede observarse en nuestro entorno cotidiano, a nadie escapa cómo, desde hace unas décadas hasta hoy día, el término diseño se encuentra en un momento de gran popularidad. Un vocablo que ya de por sí es utilizado en nuestro léxico actual como sinónimo de snobismo y modernidad, incluso para quienes no tienen idea de la envergadura y complejidad que subyace en la historia de una de las palabras más polisémicas de nuestra reciente historia. No obstante, hasta llegar a este punto álgido en el que nos encontramos, la historia del diseño es la historia de diversas evoluciones paralelas de las sociedades modernas y posmodernas, desarrollos en ámbitos que van de lo industrial a lo cultural, en todas aquellas civilizaciones tendentes a la globalización y al control de los mercados desde diferentes aspectos.
