Published: August 2019

Understanding the impacts of climate on insect pest population dynamics is crucial in forecasting pest outbreaks and developing a sustainable pest management strategy. The orange wheat blossom midge, Sitodiplosis mosellana (Géhin), is a chronic winter wheat (Triticum aestivum L.) pest in China, and its population density can strongly fluctuate. We analyzed climate factors (temperature and precipitation) associated with population dynamics of S. mosellana in a large-scale field trial in central China from 1984 to 2013 using Generalized linear mixed effects models. We found total precipitation during January–March was significantly positively correlated with population density of S. mosellana, whereas temperature parameters were not correlated with the population levels. Moreover, S. mosellana population size was significantly negative effected by interaction between temperature and precipitation, which showed that high precipitation with low temperature in spring also reduced the population density. This suggests that annual population size of S. mosellana in Central China is determined by soil moisture in early spring. These results provide basic information that will help in forecasting population levels and in developing a sound pest management strategy for S. mosellana.

To determine whether an intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) in eyes with diabetic macular edema (DME) affects the vascular infarction-related molecules (VIRMs). Nineteen eyes with DME were treated with 0.5 mg of intravitreal ranibizumab (IVR), and 22 eyes with DME were treated with 2 mg of intravitreal aflibercept (IVA). Blood was collected before, 1 week and 1 month after the injections. Aqueous humor was collected before and 1 month after the injections. The concentration of the VIRMs (cardiac myoglobin, cardiac troponin, intercellular adhesion molecule, monocyte chemotactic protein-1, matrix metalloproteinase-8, placental growth factor [PlGF], tenascin-C, tissue inhibitor of metalloproteinase-1, thrombospondin-2, vascular cell adhesion molecule-1, and VEGF) were determined by the multiplex assay. After the single injection of both types of anti-VEGF agents, the concentration of aqueous VEGF decreased significantly (P < 0.01). The plasma VEGF was reduced significantly at 1 week after the IVA (93.7 ± 17.6 to 39.5 ± 11.6 pg/ml; P < 0.01) but no significant change was seen after IVR (120.2 ± 11.3 to 137.4 ± 17.7 pg/ml). No significant changes were detected for the other VIRMs in the plasma and aqueous. A single intravitreal injection of anti-VEGF for DME does not significantly affect the concentration of several VIRMs.

Published: August 2019

Deficiency of propionyl-CoA carboxylase causes propionic acidemia and deficiencies of methylmalonyl-CoA mutase or its cofactor adenosylcobalamin cause methylmalonic acidemia. These inherited disorders lead to pathological accumulation of propionyl-CoA which is converted in Krebs cycle to methylcitrate (MCA) in a reaction catalyzed by citrate synthase. In healthy individuals where no propionyl-CoA accumulation occurs, this enzyme drives the condensation of acetyl-CoA with oxaloacetate to produce citric acid (CA), a normal Krebs cycle intermediate. The competitive synthesis of CA and MCA through the same enzymatic mechanism implies that increase in MCA production is accompanied by decrease in CA levels. In this study, we assessed MCA concentration and the ratio of MCA/CA as plausible markers for propionic and methylmalonic acidemias. We measured MCA and CA in dried blood spots using liquid chromatography tandem mass spectrometry. The reference ranges of MCA, CA and MCA/CA in 123 healthy individuals were ≤0.63 µmol/L, 36.6–126.4 µmol/L and 0.0019–0.0074, respectively. In patients with propionic and methylmalnic acidemias (n = 7), MCA concentration ranged between 1.0–12.0 µmol/L whereas MCA/CA was between 0.012–0.279. This is the first report to describe the potential role of MCA and MCA/CA in dried blood spots as diagnostic and monitoring biomarkers for inherited disorders of propionyl-CoA metabolism.
Speeded-Up Focus Control of Electrically Tunable Lens by Sparse Optimization
Authors: Iwai Daisuke , Izawa Hidetoshi , Kashima Kenji , Ueda Tatsuyuki , Sato Kosuke
Published: August 2019

Electrically tunable lenses (ETL), also known as liquid lenses, can be focused at various distances by changing the electric signal applied on the lens. ETLs require no mechanical structures, and therefore, provide a more compact and inexpensive focus control than conventional computerized translation stages. They have been exploited in a wide range of imaging and display systems and enabled novel applications for the last several years. However, the optical fluid in the ETL is rippled after the actuation, which physically limits the response time and significantly hampers the applicability range. To alleviate this problem, we apply a sparse optimization framework that optimizes the temporal pattern of the electrical signal input to the ETL. In verification experiments, the proposed method accelerated the convergence of the focal length to the target patterns. In particular, it converged the optical power to the target at twice the speed of the simply determined input signal, and increased the quality of the captured image during multi-focal imaging.
Local light-activation of the Src oncoprotein in an epithelial monolayer promotes collective extrusion

Published: August 2019

Transformed isolated cells are usually extruded from normal epithelia and subsequently eliminated. However, multicellular tumors outcompete healthy cells,  highlighting the importance of collective effects. Here, we investigate this situation in vitro by controlling in space and time the activity of the Src oncoprotein within a normal Madin–Darby Canine Kidney (MDCK) epithelial cell monolayer. Using an optogenetics approach with cells expressing a synthetic light-sensitive version of Src (optoSrc), we reversibly trigger the oncogenic activity by exposing monolayers to well-defined light patterns. We show that small populations of activated optoSrc cells embedded in the non-transformed monolayer collectively extrude as a tridimensional aggregate and remain alive, while the surrounding normal cells migrate towards the exposed area. This phenomenon requires an interface between normal and transformed cells and is partially reversible. Traction forces show that Src-activated cells either actively extrude or are pushed out by the surrounding cells in a non-autonomous way.

We develop and analyze a model for the interaction of a quasi-Newtonian free fluid with a poroelastic medium. The flow in the fluid region is described by the nonlinear Stokes equations and in the poroelastic medium by the nonlinear quasi-static Biot model. Equilibrium and kinematic conditions are imposed on the interface. We establish existence and uniqueness of a solution to the weak formulation and its semidiscrete continuous-in-time finite element approximation. We present error analysis, complemented by numerical experiments.
Envisioning ambiances: Representing (past,present and future) atmospheres for architecture and the built environment
Authors: Lescop Laurent , Kępczyńska-Walczak Anetta
Published: August 2019

The concept of “ambiance” has been shaped over the years by questioning the interactions between three attractors: architecture and the city, climatic and sound phenomena, uses and perception. Studied in pairs, each of these attractors refers to very different disciplinary fields; architecture and phenomena concern the physics of the city, architecture and uses interest sociology and uses and phenomena are rather turned to comfort. Studies concerning ambiances are therefore highly interdisciplinary and raise many questions: living spaces, urban renewal and heritage, urban prospective and the city as a stage. For this, many conceptual and technical tools are mobilized: digital tools for simulation and immersion, investigation, surveys and storytelling, prototyping, field action. What may be new in the field of academic studies is the awareness of artistic creation as a resource for the use of digital tools, storytelling and the representation of complexity through original means.
Traditional and Digital Representations of Atmosphere in Architecture. A first systematisation
Authors: Di Mascio Danilo , Putra Yvette
Published: August 2019

In architecture, atmosphere and its many implications have, in recent years, received increased attention. This paper considers atmosphere in architectural representation, and begins with an exploration of different definitions of these atmospheric representations. This paper then identifies and summarises representations of atmosphere in architecture and their key aspects, and proposes, in the form of a timeline, a preliminary systematisation of these aspects. This paper considers both traditional and digital representations of atmosphere in architecture, and focuses on aesthetic and emotional qualities of atmosphere. Thus, this paper is not limited to realistic and scientific approaches of atmosphere as meteorological conditions, but extends to atmosphere as emotions and mood. This paper also suggests cross-fertilisation, in the representation of atmosphere, between architecture and other fields. Therefore, while this paper explores atmospheric representations in architecture, it establishes its discussions by crossing disciplinary boundaries. It is anticipated that this paper will encourage further research, including recommendations for negotiating the apparent incompatibility of traditional and digital representations, to maintain qualities characterising well-known examples from the past.
Mixed Robotic Interface Г : Searching for a hybrid cyber-physical design/experience interface using virtual/actual robots
Authors: Poustinchi Ebrahim
Published: August 2019

Mixed Robotic Interface is a project-based design-research investigation, studying new ways of creating hybridized cyber-physical design and experience interfaces, at the intersection of robotics—as its core component, and augmented reality, game design, projection mapping, and digital fabrication. Mixed Robotic Interface Г—as part of Mixed Robotic Interface series of research projects, focuses on using “actual” and “virtual” robot arms as a possible creative medium and extensions of design/gaming environment creating immersive atmospheres for “experiencing” design. This research questions the possibilities of creating an architectural/spatial atmosphere through digitally enhanced experiences. Different from some of the current experiments with augmented reality (AR), virtual reality (VR) and projection-mapping in architecture, Mixed Robotic Interface Г is not looking into “immersive” experience as a way to “blur” the boundaries of digital and physical—similar to virtual reality experience with headsets. Instead, Mixed Robotic Interface Г creates a recognizable gap between real and virtual to open up a creative space for the user/audience to be involved between these two mediums. Mixed Robotic Interface Г uses para-fictional storytelling as a way to engage the audience with the experience and to create continues atmospheric qualities.
Building the city as a stage, the example of Nantes
Authors: Gangloff Emmanuelle
Published: August 2019

At a time when cities try to stand out from one another, the construction of ambiances is brought back to the foreground of urban, social and cultural dynamics in metropolises. With this contribution, we aim at taking the example of Nantes and the Machines of the Isle of Nantes to show the transformations of an industrial territory into a cultural open stage with cultural practices. Indeed, following the shutdown of the shipyards in the 1990s, the city pursued a major cultural policy to make the industrial wastelands attractive. In successive steps, the temporary artistic practices changed urban ones, based on the question of ambiances and their narrative. Favouring the implementation of projects taking place in public spaces, the city became a 360°-urban scene. As opposed to a generic city, Nantes turned urban scenography into a way to single itself out, by accompanying the creation of plots and narratives around its territory. Between artistic experiments and narrative, Nantes thus appears as a stage-city that invites to include user experiences.
Temporal Sections Conceptual Tool: Articulating Space and Time in Representing Urban Ambiances
Authors: Gamal Said Noha
Published: August 2019

This article aims to present a new methodological protocol and a representation tool that articulates both space and time in understanding urban ambiances: temporal sections. The elaboration of this conceptual tool is based on a theoretical background dealing with the palimpsest of urban ambiances. The urban palimpsest is a metaphor underlying the dynamic of the formation process of the territory resulting from a temporal, spatial and social stratification that manifests in the lived experience. Combining urban transect, a geographical tool, and stratigraphy, a geological one, temporal sections represent the sensory experience as a palimpsest that integrates the different pasts and projects on the future. This tool provides a very specific way of immersion and opens new realm in constructing a storytelling; it proposes a rereading and writing the ambiance in depth.

Traversing and sculpting scape through pattern development: Blending the natural and the built to promote ambiance in early architectural education
Authors: Barry Kristin , Burns Sean
Published: August 2019

In the formative years of their education, beginning design students are often equipped with several predetermined biases and stereotypical notions about architecture, with specific design intentions centered around how architecture should look, rather than how it should perform. The intent of this paper is to dispel these preconceptions by addressing the iterative design process through conceptual parameters of pattern and module creation, population, and manipulation in an effort to provide students with an alternative perspective for how architecture can create a dialogue with its environment and facilitate the transition from “thing seeing” to “pattern seeing.” In two projects examined in this paper, students were asked to initiate the design process by exploring and testing the inherent strengths and constraints of pattern formations through the lens of a scape and constructed assembly, each of which would focus on principles of ambiance and spatial qualities, rather than relying on traditional architectural typologies. By developing these conceptual projects, students were able to break away from their preconceptions of what architecture is, and instead focus on what architecture could be with a reinvention of the design process.
Experiments with visible and invisible materials: designing and building an ambiance
Authors: Drozd Céline , Meunier Virginie , Mabire Antoine
Published: August 2019

This article relies on a workshop called “materials of ambiances” that is taking place at the Graduate School of Architecture of Nantes. It aims for the students to question the qualities of ambiances within spaces with an approach through the concept of material, making them aware of invisible materials (ambiances) from the manipulation of visible materials (building materials). The experimentation with materials holds a significant place: the students are asked to build an ambiance device to create a sensory experience in order to highlight every sensory quality of a material capable of producing an ambiance. The materials used for this experiment are mostly from fields beyond architecture as to think of potential misappropriations. It is about making sure that the student tests by himself the materials and recreates the connection between data from the experiment, and the physical characteristics given by the manufacturers and industrialists. The pedagogical experience that we present aims at creating within students an interest for the built material, to develop ambiance intentions to qualify projected spaces, which are not always measurable but always noticeable. This article proposes to turn back to the way the qualities of ambiances are felt, the misappropriations of materials are perceived, as well as the perspectives on the evolution of the architectural design process. This contribution is illustrated by an ambiance device whose the name is “Cosmic dream” built in 2018/2019 by Marilou Bach, Hugo Falaise, Carole Lyssandre and Charlotte Say.
A network as a source of knowledge for the education of an architect
Authors: Asut Melis Baloglu , Demir Yüksel
Published: August 2019

In a learning space, whether it is surrounded by digital tools or not, the way a tutor represents the information is usually in a linear fashion. However, e-learning platforms have already started to support the learner and a new paradigm for learning. In light of these thoughts and concerns, this paper is focused on the education of an architect and examines potential e-learning platforms including BlackBoard, Facebook in the case of an architectural course, EdX, and Khan Academy Knowledge Map based on the types of visual narrative, the aim of the platform, the information visualization quality, and data types. As an output, this study creates a comparative visualization to see and discuss the potentials of the tools for the education of an architect. After the analysis of e-learning platforms, this study concludes that (1) an education model based on a network can help architects to see the big picture, however it also causes data reduction and loss, (2) an education model based on a network allows architects to create their own learning paths and share it with their colleagues, (3) an education model based on a network may be a sustainable platform for architects from different experience levels and enhance the communication between them to support the youngers’ education, 4) an education model based on network decentralizes the process of learning and enriches it through the interaction between other learners, concepts, thoughts, and objects, (5) an education model based on network bridges the gap between what one already knows and what one needs to know to understand the whole picture, (6) an education model based on network gives the opportunity to compare previous years’ feedbacks, concepts, and thought in one medium.
360° VR for Qualifying Daylight Design
Authors: Kreutzberg Anette , Naboni Emanuele
Published: August 2019

This paper describes the initial findings in an ongoing project aimed at bridging the gap between quantitative daylight simulations and visually perceived daylight quality, using 360° rendered panoramas and animations displayed in virtual reality. A daylight studio equipped with a simple façade pattern for a simultaneous Thermal Delight study was used as case study and test room. The test room was recorded with a 360° camera in sequential image series on days with different weather conditions. The resulting 360° VR time-lapse recordings were proposed for visual diurnal daylight analysis as supplement to thermal measurements used for calibrating and varying the façade pattern on site and in a corresponding thermal simulation model. A comparative experiment was set up to calibrate the perceived visual qualities and ambiance of daylight in 360° photographic panoramas viewed in VR, compared to the perceived visual qualities and ambiance of the real world site. Subjective visual evaluations of the virtual as well as the real space were recorded based on 15 people answering to a questionnaire. Results from the comparative experiment indicate a variety in perception of daylight quality and ambiance but a rather uniform perception of daylight brightness in 360° photographs that can be transferred to 360° rendered panoramas.
Maintaining the ambiance of regenerated postmilitary complexes − current and emerging possibilities
Authors: Rudnicka-Bogusz Marta Małgorzata
Published: August 2019

Ambiance provides scholarly value to historic architectural precincts and complexes. Through it, the built environment − a corpus of buildings − becomes an environment with its own unique narrative. It grants us the possibility of interacting with the atmosphere of the place as it was in the epoch. However, due to the nature of modern development, living historic cities are changing dynamically. To stay in use, and thus continue their scholastic mission, historic urban areas need to be integrated into local development through either within-use adaptation or conversion to new functions. For historic barrack complexes, this usually means extensive redevelopment. The difficulty comes from accommodating quotidian use while maintaining its historiographic values, especially with historically sensitive sites. This means the designers should take the legibility of the original complex into consideration in their designs and provide suitable aids to visitors. As it turns out there is not a universal approach, instead different approaches allow preservation of various degrees of the original ambiance.

Acoustic comfort in the living environment and its association with noise representation: A systematic review
Authors: Jahangeer Farrah
Published: August 2019

Noise is commonly known to have adverse health effects on residents in urban living environment. In the past, great focus has been placed on the impact of external traffic noise on residents’ health and the development of urban noise mapping. On the other hand, neighbourhood noise − a combination of noise generated from outside residences and noise generated from within residences − are also considered to be as detrimental as external traffic noise and are yet to be widely investigated. This paper focuses on the systematic review of studies assessing neighbourhood noise with the intention of determining the presence of architectural variables and methods of noise representation for micro-scale areas. 153 articles are retrieved from specific research databases and out of which 12 were considered to be relevant to the study. The results indicate that architectural variables present in the studies were mostly related to the analysis of external traffic noise and that representation of noise in analyses were rarely devised which highlights the need for further investigation in this area.

Authors: Freitas Anderson , Ramos Lucas S. , Dantas Érgon LAB , Giordano Neto Vincenzo , Godinho Patrick F. , Shimano Antônio C.
Published: August 2019

Objetivo Avaliar, por meio de ensaio biomecânico, a resistência e a energia necessária para ocorrência de fratura do fêmur proximal em osso sintético após retirada de parafusos canulados em forma de triângulo invertido e comparar os resultados obtidos com técnica de reforço utilizando polimetilmetacrilato (PMMA).

Métodos Foram utilizados 20 ossos sintéticos: 10 unidades para o grupo controle; 5 o grupo teste sem reforço, sem preenchimento após a retirada dos parafusos canulados, e 5 o para grupo teste com reforço com PMMA. A análise biomecânica foi realizada simulando queda sobre o grande trocânter utilizando máquina servo-hidráulica.

Resultados Todos os corpos de prova dos grupos controle e sem cimento apresentaram fratura baso-cervical. No grupo teste com preechimento, três corpos de prova apresentaram fratura baso-cervical, enquanto que dois deles apresentaram fratura na parte próxima ao ponto de fixação no dispositivo (região diafisária do fêmur), sendo um deles associado a fratura do colo femoral. Foi utilizada uma média de 8.2 ml de polimetilmetacrilato no preenchimento dos três pertuitos do grupo com preenchimento. Segundo a análise de variância (ANOVA, na sigla em inglês) para um fator e o teste de comparações múltiplas de Tukey, ao nível de 5%, o grupo com cimento apresentou diferença significativa em relação aos outros grupos em todos os parâmetros.

Conclusão A simples retirada dos parafusos canulados não apresentou redução significativa da carga máxima e da energia necessárias para a ocorrência de fratura; porém, o reforço do fêmur proximal com polimetilmetacrilato aumentou significativamente esses parâmetros, causando mudanças no padrão fraturário.

Objective To compare the Latin American and European assisted reproductive technology (ART) registries regarding data accessibility and quality, treatment utilization, effectiveness, safety, and quality of services.

Methods We performed an ecological study using data from scientific publications of Latin American and European registries that report cycles initiated during 2013 (the most recent registries available until December of 2017). The summarized data are presented as frequencies, percentages, minimum-maximum values, and absolute numbers.

Results Reporting clinics and cycle treatments were unevenly distributed between the participating countries for both registries, although access to ART is 15 times greater in Europe. In Latin America, individual services participate voluntarily reporting started cycles until cancellation, birth or miscarriage, while in Europe it varied among countries. It makes the data available from Latin America more uniform, although lesser representative when compared with European ones, given that reporting is compulsory for most countries. The cumulative live birth rate was better in Latin America. Female age, use of intracytoplasmic sperm injection (ICSI), cycles with transfer of ≥ 3 embryos, as well as multiple pregnancy rates were greater in the Latin American Register of Assisted Reproduction (RLA, in the Portuguese acronym). Assisted reproductive technology complications, such as ovarian hyperstimulation syndrome, hemorrhage, and infections were also higher in Latin America, although they are extremely uncommon in both regions.

Conclusion Both regions have points to improve in the quality of their reports. Latin America has produced a more uniform reporting, their clinical results are generally comparable and sometimes higher than the European ones. In contrast, the safety of the treatment was higher in Europe, with lower rates of complications, especially multiple pregnancies.

Objetivo Avaliar e comparar a osteointegração dos enxertos ósseos congelados irradiados e não irradiados utilizados em 21 pacientes submetidos a revisão de prótese do quadril pela técnica Exeter.

Métodos Foi realizado estudo retrospectivo de 21 pacientes submetidos a revisão de artroplastia do quadril pela técnica Exeter com utilização de tecidos ósseos tratados ou não com radiação gama no período entre 2013 e 2014. Dividimos os pacientes em dois grupos, de acordo com o uso do enxerto tratado ou não com radiação ionizante (raios gama), que foram, portanto, classificados como: grupo irradiado e não irradiado. Os resultados da osteointegração por análise radiográfica destes enxertos foram comparados no pós-cirúrgico de 6 e 12 meses.

Resultados Quando comparamos a osteointegração dos enxertos no pós-cirúrgico de 6 e 12 meses de todos os pacientes, notamos que houve diferença significativa entre as avaliações radiográficas neste período (p = 0,031). Dos pacientes estudados, 7 pertenciam ao grupo irradiado, e 14, ao grupo não irradiado. Não foram observadas diferenças estatisticamente significativas (p = 0,804) quando a osteointegração entre os grupos irradiados e não irradiados foi comparada.

Conclusão Não houve diferença significativa no uso de enxerto irradiado e não irradiado nas revisões de artroplastias do quadril pela técnica Exeter.

Authors: Fante Júlia Ferreira , Silva Thais Daniel , Mateus-Vasconcelos Elaine Cristine Lemes , Ferreira Cristine Homsi Jorge , Brito Luiz Gustavo Oliveira
Published: August 2019

Objective We sought to investigate whether women present adequate knowledge of the main pelvic floor disorders (PFDs) (urinary incontinence – UI, fecal incontinence – FI, and pelvic organ prolapse – POP).

Data sources A systematic review was performed in the MEDLINE, PEDro, CENTRAL, and Cochrane databases for publications from inception to April 2018.

Selection of studies A total of 3,125 studies were reviewed. Meta-analysis was not possible due to the heterogeneity of primary outcomes and the diversity of instruments for measuring knowledge. The quality of the articles included in the analysis was evaluated with the Newcastle-Ottawa Scale (NOS) adapted for cross-sectional studies.

Data collection Two authors performed data extraction into a standardized spreadsheet.

Data synthesis Nineteen studies were included, comprising 11,512 women. About the methodological quality (NOS), most of the studies (n = 11) presented a total score of 6 out of 10. Validated questionnaires and designed pilot-tested forms were the most frequently used ways of assessing knowledge. Some studies were stratified by race, age, or group minorities. The most used questionnaire was the prolapse and incontinence knowledge questionnaire (PIKQ) (n = 5). Knowledge and/or awareness regarding PFD was low to moderate among the studies. Urinary incontinence was the most prevalent PFD investigated, and the most important risk factors associated with the lack of knowledge of the pelvic floor were: African-American ethnicity (n = 3), low educational level (n = 4), low access to information (n = 5) and socioeconomic status (n = 3).

Conclusion Most women have a gap in the knowledge of pelvic floor muscle dysfunctions, do not understand their treatment options, and are not able to identify risk factors for these disorders.
Tunnel magnetoresistance effect in a magnetic tunnel junction with a B2-Fe3Sn electrode
Authors: Goto Y. , Yanase T. , Shimada T. , Shirai M. , Nagahama T.
Published: August 2019

In magnetic tunnel junctions (MTJs), the tunnel resistance varies as a function of the relative magnetic configuration of the electrode, in an effect called tunnel magnetoresistance (TMR). The material of which the electrodes are composed is of great importance, because TMR is very sensitive to the electronic states of the electrodes. Additionally, structural defects at the interface also have a significant influence on TMR. In this study, we employ B2-Fe3Sn as the magnetic electrode of MTJs. The use of Fe3Sn could solve the problem of lattice mismatch between Fe and MgO. However, the presence of dissimilar atoms in the electrodes or interface oxidation could be a source of defects at the interface. We find that MTJs with Fe3Sn exhibit a TMR of 50% and an asymmetric bias dependence.
Nonlinear convection flow of Williamson nanofluid past a radially stretching surface
Authors: Ibrahim Wubshet , Gamachu Dachasa
Published: August 2019

In the current study, a non-linear convection flow of Williamson nanofluid past a radially stretching surface under the application of electric field has been inspected. The simplified joined non-linear ordinary differential equations are acquired from the partial differential equations which are formulated from the flow problems and then, are altered into dimensionless form employing appropriate resemblance transformation and also, the multivariate nonlinear terms are linearised with the help of Taylor series expansion technique. Then ensuing nonlinear ordinary partial differential equations with matching boundary conditions are solved numerically by utilizing spectral Quasilinearization method (SQLM). The influence of pertinent parameters on different flow fields are probed and conferred in depth by means of numerous plots and tables. The outcomes demonstrate that the velocity profile f′(η) enlarges as the value of electric field E1, buoyancy λ and nonlinear convection λ1 parameters are upgraded. Also, both temperature and concentration profiles augment with a boost in values of magnetic field and thermopherasis parameters. The results also signify that, for bigger values of magnetic field parameter M, the numerical value of local Nusselt number and Sherwood number are declined.
Solar thermophotovoltaics: Progress, challenges, and opportunities
Authors: Wang Yang , Liu Haizhou , Zhu Jia
Published: August 2019

Solar thermophotovoltaics (STPV), which utilizes the full spectrum of solar energy, possesses a high theoretical system efficiency of 85.4% that well beats the Shockley-Queisser limit of traditional photovoltaics. However, the experimental efficiency reported so far is still less than 10% due to a variety of optical and/or thermal losses. Based on the system efficiency analysis, we first summarize the key components of ideal STPV, which can be divided into the material/structure level and system level. We then introduce new types of solar powered thermophotovoltaics and hybrid STPV systems integrated with other energy conversion systems. A perspective is provided at the end to discuss the challenges and opportunities.
