This report presents the main results of the project. The project has been started at the end of 2007 and has been successfully finished in December 2008. The present project of ALE AirLight Energy aims at the engineering investigation and design of a novel concept of a solar collector system for efficient and cost-effective solar thermal power generation. The technology exploits an air-inflated reflective structure to concentrate solar radiation. This new arrangement reduces investment costs of the collector field and promises to be economically competitive. A first prototype, built in 2007, has been redesigned and heavily modified during this project. In the new configuration, by using secondary mirrors, the focal area is located close to the main structure and allows the integration of the receiver into the inflated structure. The topics developed in this document are as follows: (i) Design solutions for the concentrated energy receiver suitable for the revised SolAir concentrator concept. (ii) Solar flux simulation via Monte Carlo method. (iii) New version of the ALE AirLight Energy concentrator prototype. (iv) Prototype radiative flux measurements. (author)

Building codes as barriers to solar heating and cooling of buildings

Energy Technology Data Exchange (ETDEWEB)

Meeker, F.O. III

1978-04-01

The application of building codes to solar energy systems for heating and cooling of buildings is discussed, using as typical codes the three model building codes most widely adopted by states and localities. Some potential barriers to solar energy systems are found, federal and state programs to deal with these barriers are discussed, and alternatives are suggested. To remedy this, a federal program is needed to encourage state adoption of standards and acceptance of certification of solar systems for code approval, and to encourage revisions to codes based on model legislation prepared for the federal government by the model codes groups.

Building Design Guidelines for Solar Energy Technologies

Givoni, B.

1989-01-01

There are two main objectives to this publication. The first is to find out the communalities in the experience gained in previous studies and in actual applications of solar technologies in buildings, residential as well as nonresidential. The second objective is to review innovative concepts and products which may have an impact on future developments and applications of solar technologies in buildings. The available information and common lessons were collated and presented in a form which, hopefully, is useful for architects and solar engineers, as well as for teachers of "solar architecture" and students in Architectural Schools. The publication is based mainly on the collection and analysis of relevant information. The information included previous studies in which the performance of solar buildings was evaluated, as well as the personal experience of the Author and the research consultants. The state of the art, as indicated by these studies and personal experience, was summarized and has served as basis for the development of the Design Guidelines. In addition to the summary of the state of the art, as was already applied in solar buildings, an account was given of innovative concepts and products. Such innovations have occurred in the areas of thermal storage by Phase Change Materials (PCM) and in glazing with specialized or changeable properties. Interesting concepts were also developed for light transfer, which may enable to transfer sunlight to the core areas of large multi story nonresidential buildings. These innovations may have a significant impact on future developments of solar technologies and their applications in buildings.

The first conference organized by the newly established Canadian Solar Buildings Research Network (SBRN) was held in conjunction with the thirty-first annual conference of the Solar Energy Society of Canada Inc (SESCI). The conference was attended by top researchers from 10 Canadian Universities to promote innovative research and development in solar energy applications and to advance the awareness of solar energy in Canada. It featured special events such as trade shows, photovoltaic workshops, a course in ESP-r simulation, tours of solar houses and other events focused on the economic, environmental and socio-economic benefits of solar technology, including the potential to reduce greenhouse gas emissions. SBRN was founded on the premise that university researchers should focus on solar energy applications for buildings. Several presentations proposed action plans to accelerate the implementation of solar energy through the use of innovative building technologies and sustainable energy policies. Other major issues of interest were also discussed, including the development of the net-zero energy solar home and grid-connection issues. The sessions of the conference were entitled: solar thermal systems; solar electricity; building integrated photovoltaic systems; design issues and tools; integrating PV and solar thermal in buildings; daylighting and solar radiation modeling; fenestration and shading; PV manufacturing and solar electricity resources. The proceedings featured 41 refereed papers and 13 poster presentations, all of which have been catalogued separately for inclusion in this database. refs., tabs., figs

Application of Sol-Gel Method as a Protective Layer on a Specular Reflective Surface for Secondary Reflector in a Solar Receiver

Energy Technology Data Exchange (ETDEWEB)

Afrin, Samia; Dagdelen, John; Ma, Zhiwen; Kumar, Vinod

2017-01-01

Highly-specular reflective surfaces that can withstand elevated-temperatures are desirable for many applications including reflective heat shielding in solar receivers and secondary reflectors, which can be used between primary concentrators and heat collectors. A high-efficiency, high-temperature solar receiver design based on arrays of cavities needs a highly-specular reflective surface on its front section to help sunlight penetrate into the absorber tubes for effective flux spreading. Since this application is for high-temperature solar receivers, this surface needs to be durable and to maintain its optical properties through the usable life. Degradation mechanisms associated with elevated temperatures and thermal cycling, which include cracking, delamination, corrosion/oxidation, and environmental effects, could cause the optical properties of surfaces to degrade rapidly in these conditions. Protected mirror surfaces for these applications have been tested by depositing a thin layer of SiO2 on top of electrodeposited silver by means of the sol-gel method. To obtain an effective thin film structure, this sol-gel procedure has been investigated extensively by varying process parameters that affect film porosity and thickness. Endurance tests have been performed in a furnace at 150 degrees C for thousands of hours. This paper presents the sol-gel process for intermediate-temperature specular reflective coatings and provides the long-term reliability test results of sol-gel protected silver-coated surfaces.

Feasibility study on the sol-gel deposition of nanostructured materials based on oxides and fluorides for coatings on solar collector glazing

Energy Technology Data Exchange (ETDEWEB)

Schueler, A.; Chambrier, E. De

2005-10-15

This illustrated annual report reviews work done at the Federal Institute of Technology (EPFL) in Lausanne, Switzerland, on the architectural integration of thermal solar collectors into buildings. This is often limited by their black colour and the visibility of the tubes and corrugations of the absorber sheets. Although a certain freedom in the choice of colour would be desirable, the coloured appearance should not cause excessive performance degradation. Multi-layered thin film interference filters on the collector glazing can produce a coloured reflection while transmitting the non-reflected radiation entirely to the absorber. The paper describes suitable optical interference filters which have been designed and optimised by numerical simulation and that will be manufactured by the sol-gel dip-coating process. Light scattering has to be avoided, which implies a need for particle sizes much smaller than the wavelengths of the incoming light. The paper proposes that corresponding thin films should therefore consist of nano-structured materials. The sol-gel deposition of all proposed materials has been demonstrated successfully. The paper presents the results of the work using various materials including titanium-silicon mixed oxides, gold-silicon dioxide, porous silicon dioxide, magnesium fluoride and quaternary films.

2017-12-01

In the context of the construction of low-carbon cities, green cities and eco-cities, the ability of the airborne and mobile LiDAR should be explored in urban renewable energy research. As the main landscape in urban environment, buildings have large regular envelopes could receive a huge amount of solar radiation. In this study, a relatively complete calculation scheme about building roof and façade solar utilization potential is proposed, using building three-dimensional geometric feature information. For measuring the city-level building solar irradiance, the precise three-dimensional building roof and façade models should be first reconstructed from the airborne and mobile LiDAR, respectively. In order to obtaining the precise geometric structure of building facades from the mobile LiDAR data, a new method for structure detection and the three-dimensional reconstruction of building façades from mobile LiDAR data is proposed. The method consists of three steps: the preprocessing of façade points, the detection of façade structure, the restoration and reconstruction of building façade. As a result, the reconstruction method can effectively deal with missing areas caused by occlusion, viewpoint limitation, and uneven point density, as well as realizing the highly complete 3D reconstruction of a building façade. Furthermore, the window areas can be excluded for more accurate estimation of solar utilization potential. After then, the solar energy utilization potential of global building roofs and facades is estimate by using the solar irradiance model, which combine the analysis of the building shade and sky diffuse, based on the analysis of the geometrical structure of buildings.

The architectural integration of thermal solar collectors into buildings is often limited by their black color, and the visibility of tubes and corrugations of the absorber sheets. A certain freedom in color choice would be desirable, but the colored appearance should not cause excessive performance degradation. Multilayered thin film interference filters on the collector glazing can produce a colored reflection, hiding the corrugated metal sheet, while transmitting the non-reflected radiation entirely to the absorber. These interference filters are designed and optimized by numerical simulation and shall be manufactured by the sol-gel dip-coating process. The proposed colored glazed solar collectors will be ideally suited for architectural integration into buildings, e.g. as solar active glass facades. The availability of thin film materials with a refractive index lower than that of silicon favors a higher solar transmission at a given value of visible reflectance. The feasibility of the sol-gel deposition of such low refractive index materials has been demonstrated. For the development of nanostructured materials, analytical methods such as electron microscopy are extremely helpful. Important techniques of substrate pretreatment, sample cleaving, polishing, mounting, and microscope handling have been acquired. First measurements yield images of nanostructures produced by the sol-gel dip-coating process. Nanocomposite Ti{sub x}Si{sub 1-x}O{sub 2} thin films provide a large range of refractive indices. Aiming a high efficiency of the colored reflection, Ti{sub x}Si{sub 1-x}O{sub 2} based multilayered coatings have been designed and subsequently prepared by sol-gel dip-coating. The energy efficiency M = R{sub VIS}/(100%-T{sub sol}) of the obtained colored reflection amounts up to 2.4. For a convincing demonstration sufficiently large samples of high quality are imperatively needed. An infrastructure for the handling of A4 sized samples has been established

2012-07-01

Full Text Available The aim of this study is the estimation of solar irradiance on building roofs in complex Alpine landscapes. Very high resolution geometric models of the building roofs are generated by means of advanced automated image matching methods. Models are combined with raster and vector data sources to estimate the incoming solar radiation hitting the roofs. The methodology takes into account for atmospheric effects, site latitude and elevation, slope and aspect of the terrain as well as the effects of shadows cast by surrounding buildings, chimneys, dormers, vegetation and terrain topography. An open source software solution has been developed and applied to a study area located in a mountainous site and containing some 1250 residential, commercial and industrial buildings. The method has been validated by data collected with a pyranometer and results made available through a prototype WebGIS platform.

Solar energy conscious allotting and building

International Nuclear Information System (INIS)

Moor, R.; Winter, R.

1992-10-01

In order to use solar energy now and in the future several measures should be taken in the field of urban development and housing construction. A number of policy instruments is available to the local governments to stimulate the use of solar energy. However, little use is made of these possibilities so far. In many municipalities there are uncertainties about the financial consequences of solar energy conscious building. In practice it appears that there are hardly any extra costs for the infrastructure if building blocks and roofs are designed and built with south orientation. Also possibilities to minimize the investment barrier for the occupants of the houses are available. An overview is presented of the policy instruments and practical examples are given for the Dutch municipalities Gouda, Schiedam, Heerhugowaard, Delft and Haarlemmermeer. 2 tabs., 2 appendices, 6 refs

Parkin, B.; Allen, D.

1981-01-01

The homebuilding industry can open the way to wide-scale residential use of solar energy. Under the Northwest Power Act, the Department of Energy's Bonneville Power Administration, Western Solar Utilization Network and the Solar Energy Research Institute are working together with the Home Builders Association of Metropolitan Portland and the Portland chapter of the American Institute of Architects on a program that will affect 7 cities in the Pacific Northwest. Modeled after the successful Denver Metro Homebuilders Program, the project is being implemented in 3 cities in 1981 and three additional cities in 1982. In each of the 7 cities builders and developers will be provided with design, performance monitoring and marketing assistance for constructing passive solar prototypes. The result is ten passive solar homes of superior design and of an affordable price in each city. The secondary result of this program is expected to be a total of 2700 solar homes produced outside the program by builders from 1981-1985. Builders influenced to build passive solar homes outside the program could result in as many as 500,000 homes produced by the year 2000.

Research and Development of solar cell frame. Study on solar cell array solid with building material-business building

Energy Technology Data Exchange (ETDEWEB)

1986-08-01

This is a NEDO annual report for 1985. A feasibility study was carried out from the viewpoints demanded both from the building material side and the solar cell. Evaluation from the technical, institutional, and economical viewpoints indicated the possibility of using a roof material solid with carbon-fiber-reinforced concrete and a curtain wall. The solar cell module was verified as a building material to be resistant against the external force, water, and heat. A problem left is how to enlarge the module. Integrated use of CFRC (Carbon Fiber Reinforced Concrete) and a cell of maximum size (1,240 x 700 mm), which is industrially available, can be expected. Present solar cell array can be utilized as a building material as it is for a curtain wall. Cost calculation of the CFRC solid roofing material indicates 276 yen/KWH for 15 years depreciation, 10 % residual value, and 8% annual interest, which is a little expensive, but this cost may be applicable to the use as a curtain wall.

Knowles, R.L.; Berry, R.D.

1980-04-01

Solar energy utilization in urban areas requires public guarantees that all property owners have direct access to the sun. The study examines the implications of this premise in relation to the need for cities to also encourage or accommodate rebuilding and future development. The public policy mechanism for guaranteeing solar access is conceptualized as a solar zoning envelope that allows the largest possible building bulk on a land parcel without shadowing neighboring properties during specified times. Step-by-step methods for generating solar envelopes are described with extensive drawings, showing a variety of urban platting and lot configurations. Development and design possibilities are examined on a selected set of Los Angeles sites with typically diverse urban characteristics. Envelope attributes suitable for encouraging moderate-density commercial and residential building are examined in the context of two hypothetical but realistic development programs: one for speculative office buildings and one for condominium housing. Numerous illustrations of envelope forms and prototypical building designs are provided. The results of development simulation studies on all test sites are tabulated to show building bulk, density, land-coverage and open space characteristics obtainable under the hypothesized envelopes.

First measurements yield images of nanostructures produced by the sol-gel dip-coating process. Nanocomposite Ti{sub x}Si{sub 1-x}O{sub 2} thin films provide a large range of refractive indices. Aiming a high efficiency of the colored reflection, Ti{sub x}Si{sub 1-x}O{sub 2} based multilayered coatings have been designed and subsequently prepared by sol-gel dip-coating. The energy efficiency M = R{sub VIS}/(100%-T{sub sol}) of the obtained colored reflection amounts up to 2.4. For a convincing demonstration sufficiently large samples of high quality are imperatively needed. An infrastructure for the handling of A4 sized samples has been established

Blade-coated sol-gel indium-gallium-zinc-oxide for inverted polymer solar cell

Directory of Open Access Journals (Sweden)

Yan-Huei Lee

2016-11-01

Full Text Available The inverted organic solar cell was fabricated by using sol-gel indium-gallium-zinc-oxide (IGZO as the electron-transport layer. The IGZO precursor solution was deposited by blade coating with simultaneous substrate heating at 120 °C from the bottom and hot wind from above. Uniform IGZO film of around 30 nm was formed after annealing at 400 °C. Using the blend of low band-gap polymer poly[(4,8-bis-(2-ethylhexyloxy-benzo(1,2-b:4,5-b’dithiophene-2,6-diyl-alt- (4-(2-ethylhexanoyl-thieno [3,4-b]thiophene--2-6-diyl] (PBDTTT-C-T and [6,6]-Phenyl C71 butyric acid methyl ester ([70]PCBM as the active layer for the inverted organic solar cell, an efficiency of 6.2% was achieved with a blade speed of 180 mm/s for the IGZO. The efficiency of the inverted organic solar cells was found to depend on the coating speed of the IGZO films, which was attributed to the change in the concentration of surface OH groups. Compared to organic solar cells of conventional structure using PBDTTT-C-T: [70]PCBM as active layer, the inverted organic solar cells showed significant improvement in thermal stability. In addition, the chemical composition, as well as the work function of the IGZO film at the surface and inside can be tuned by the blade speed, which may find applications in other areas like thin-film transistors.

Full Text Available Solar technology is becoming increasingly popular. For example, the production of solarcells quadrupled in the 1999-2004 period, with a capacity of four gigawatts worldwide. Renewableenergy including solar power produces few or no harmful emissions and it is becoming increasinglyimportant to exploit it in the future. This paper presents a literature review of the application ofnumerous types of solar technology in buildings in Malaysia and identifies the challenges faced.Although several newly constructed green buildings use solar technology, Malaysia has yet to acceptit wholesale. If solar technology is to be adopted widely, then both public and private sectors mustcooperate to provide large-scale financial incentives and produce specialists in solar technology. Asthe first step, the government has established the Low Energy Office and the Green Energy Office,which use passive solar design and photovoltaic systems in their own buildings. However, the privatesector has yet to follow suit. It is anticipated that the application of solar technology in buildings willencourage sustainable development when all non-renewable energy sources decrease significantly. Ifpeople do not recognise the potential of such technology in daily life, it will soon be too late.

A deep learning pipeline for Indian dance style classification

Science.gov (United States)

Dewan, Swati; Agarwal, Shubham; Singh, Navjyoti

2018-04-01

In this paper, we address the problem of dance style classification to classify Indian dance or any dance in general. We propose a 3-step deep learning pipeline. First, we extract 14 essential joint locations of the dancer from each video frame, this helps us to derive any body region location within the frame, we use this in the second step which forms the main part of our pipeline. Here, we divide the dancer into regions of important motion in each video frame. We then extract patches centered at these regions. Main discriminative motion is captured in these patches. We stack the features from all such patches of a frame into a single vector and form our hierarchical dance pose descriptor. Finally, in the third step, we build a high level representation of the dance video using the hierarchical descriptors and train it using a Recurrent Neural Network (RNN) for classification. Our novelty also lies in the way we use multiple representations for a single video. This helps us to: (1) Overcome the RNN limitation of learning small sequences over big sequences such as dance; (2) Extract more data from the available dataset for effective deep learning by training multiple representations. Our contributions in this paper are three-folds: (1) We provide a deep learning pipeline for classification of any form of dance; (2) We prove that a segmented representation of a dance video works well with sequence learning techniques for recognition purposes; (3) We extend and refine the ICD dataset and provide a new dataset for evaluation of dance. Our model performs comparable or better in some cases than the state-of-the-art on action recognition benchmarks.

2015-01-01

Artificial lighting in office buildings accounts for about 30% of the total building energy consumption. Lighting energy is important to reduce building energy consumption since artificial lighting typically has a relatively large energy conversion factor. Therefore, previous studies have proposed a dimming control using daylight. When applied dimming control, method based on building modeling does not need illuminance sensors. Thus, it can be applied to existing buildings that do not have illuminance sensors. However, this method does not accurately reflect real-time weather conditions. On the other hand, solar power generation from a PV (photovoltaic) panel reflects real-time weather conditions. The PV panel as the sensor improves the accuracy of dimming control by reflecting disturbance. Therefore, we compared and analyzed two types of sensorless dimming controls: those based on the building modeling and those that based on solar power generation using PV panels. In terms of energy savings, we found that a dimming control based on building modeling is more effective than that based on solar power generation by about 6%. However, dimming control based on solar power generation minimizes the inconvenience to occupants and can also react to changes in solar radiation entering the building caused by dirty window. - Highlights: • We conducted sensorless dimming control based on solar power generation. • Dimming controls using building modeling and solar power generation were compared. • The real time weather conditions can be considered by using solar power generation. • Dimming control using solar power generation minimizes inconvenience to occupants

Solar on the brink : more and more engineers are being asked to integrate solar technologies into building designs

International Nuclear Information System (INIS)

Sinclair, I.

2010-01-01

Methods of integrating solar technologies into building designs were discussed in this article. Ontario's feed-in-tariff (FIT) program will make Ontario a centre for solar technology and is expected to generate new jobs in the alternative energy industry. While photovoltaic (PV) systems eliminate the need for building new electricity and distribution networks, PV systems are the least efficient solar technology in relation to economics, carbon dioxide (CO 2 ) offsets, and energy generation. Many buildings in Canada have significant ventilation air heating loads that are not best served by heat recovery technologies. The economic performance of solar thermal systems can only be understood in relation to the operational efficiency of a building's heating plant. Solar PV systems can provide returns on investment when considered alongside Ontario's FIT program tariffs. Without the tariffs, many payback periods are in excess of PV system product lifetimes. Maintenance contracts and budgets must be carefully considered when commissioning solar energy projects. 3 figs.

TiO2-SiO2 Coatings with a Low Content of AuNPs for Producing Self-Cleaning Building Materials

Directory of Open Access Journals (Sweden)

Manuel Luna

2018-03-01

Full Text Available The high pollution levels in our cities are producing a significant increase of dust on buildings. An application of photoactive coatings on building materials can produce buildings with self-cleaning surfaces. In this study, we have developed a simple sol-gel route for producing Au-TiO2/SiO2 photocatalysts with application on buildings. The gold nanoparticles (AuNPs improved the TiO2 photoactivity under solar radiation because they promoted absorption in the visible range. We varied the content of AuNPs in the sols under study, in order to investigate their effect on self-cleaning properties. The sols obtained were sprayed on a common building stone, producing coatings which adhere firmly to the stone and preserve their aesthetic qualities. We studied the decolourization efficiency of the photocatalysts under study against methylene blue and against soot (a real staining agent for buildings. Finally, we established that the coating with an intermediate Au content presented the best self-cleaning performance, due to the role played by its structure and texture on its photoactivity.

Highlights: • Acid boric can thoroughly leads to the hierarchical porous titania structure. • Boron is introduced into titania lattice which causes slight blueshift of bandgap. • The optimized sol parameters are H{sub 3}BO{sub 3}/TTiP = 0.45, DI/TTiP = 4.5, and 0.17 M. • Optimized paste parameters is not changed compared to conventional pastes. • The DSSC based on H{sub 3}BO{sub 3} catalyzed sol shows promising efficiency of 2.91%. - Abstract: The hierarchical porous photoanode of the dye sensitized solar cell (DSSC) is synthesized through non-aqueous sol-gel method based on H{sub 3}BO{sub 3} as an acid catalyst and the efficiencies of the fabricated DSSC based on these photoanodes are compared. The sol parameters of 0.17 M, water mole ratio of 4.5, acid mole ratio of 0.45, and solvent type of ethanol are introduced as optimum parameters for photoanode formation without any detectable cracks. The optimized hierarchical photoanode mainly contains anatase phase with slight shift toward higher angles, confirming the doping of boron into titania structure. Moreover, the porous structure involves two ranges of average pore sizes of 20 and 635 nm. The diffuse reflectance spectroscopy (DRS) shows the proper scattering and blueshift in band gap. The paste parameters of solid:liquid, TiO{sub 2}:ethyl cellulose, and terpineol:ethanol equal to 11:89, 3.5:7.5, and 25:64, respectively, are assigned as optimized parameters for this novel paste. The photovoltaic properties of short circuit current density, open circuit voltage, fill factor, and efficiency of 5.89 mA/cm{sup 2}, 703 mV, 0.7, and 2.91% are obtained for the optimized sample, respectively. The relatively higher short circuit current of the main sample compared to other samples is mainly due to higher dye adsorption in this sample corresponding to its higher surface area and presumably higher charge transfer confirmed by low R{sub S} and R{sub ct} in electrochemical impedance spectroscopy data.

A new solar collection system integrated on the façade of a building is investigated for Dutch climate conditions. The solar collection system includes a solar façade, a receiver tube and 10 Fresnel lenses. The Fresnel lenses Fresnel lenses considered were linear, non-imaging, line – focused with a system tracking the position of the sun that ensures vertical incidence of the direct solar radiation on the lenses. For the heating system a double-effect absorption heat pump, which requires high temperature of the heating fluid, was used, working with water and lithium-bromide as refrigerant and solution respectively. The Fresnel lens system is connected with the absorption heat pump through a thermal energy storage tank which accumulates the heat from the Fresnel lens system to provide it to the high pressure generator of the absorption heat pump. - Highlights: • The integration of Fresnel lenses in solar thermal building façades is investigated. • Using building integrated Fresnel lenses, 43% heating energy can be saved. • Energy savings in Mediterranean countries are significantly larger. • The absorption heat pump could make great contribution to energy savings for Dutch climate conditions

Lee, T. G. [Calgary Univ., Faculty of Environmental Design, AB (Canada)

1999-11-01

Education and training of students of architecture, industrial design, planning and environmental sciences in solar energy utilization, as practiced at the University of Calgary, is described. Classes are relatively small, which allows for considerable flexibility in terms of the different modes of instruction. Lectures, case studies, field trips and workshops all have their place, although the most effective and most popular mode of instruction is the hands-on approach in building and installing a solar heating system. During the course, the students build various types of solar cookers and concentrating solar collectors, including air-type and water-type flat plate collectors. Usually one solar component is built by each class, but previous projects are available for examination and monitoring. This paper elaborates upon the pedagogical basis of shop experience for architectural students. In this context it addresses issues related to shop space, materials, construction, installation testing and monitoring, as well as safety and performance of the student-constructed solar systems. 3 refs., 9 figs.

2017-01-01

Dance - as a ritual, therapy, and leisure activity - has been known for thousands of years. Today, dance is increasingly used as therapy for cognitive and neurological disorders such as dementia and Parkinson's disease. Surprisingly, the effects of dance training on the healthy young brain are not well understood despite the necessity of such information for planning successful clinical interventions. Therefore, this study examined actively performing, expert-level trained college students as a model of long-term exposure to dance training. To study the long-term effects of dance training on the human brain, we compared 20 young expert female Dancers with normal body mass index with 20 age- and education-matched Non-Dancers with respect to brain structure and function. We used diffusion tensor, morphometric, resting state and task-related functional MRI, a broad cognitive assessment, and objective measures of selected dance skill (Dance Central video game and a balance task). Dancers showed superior performance in the Dance Central video game and balance task, but showed no differences in cognitive abilities. We found little evidence for training-related differences in brain volume in Dancers. Dancers had lower anisotropy in the corticospinal tract. They also activated the action observation network (AON) to greater extent than Non-Dancers when viewing dance sequences. Dancers showed altered functional connectivity of the AON, and of the general motor learning network. These functional connectivity differences were related to dance skill and balance and training-induced structural characteristics. Our findings have the potential to inform future study designs aiming to monitor dance training-induced plasticity in clinical populations.

Initial operation of a solar heating and cooling system in a full-scale solar building test facility

The Solar Building Test Facility (SBTF) located at Hampton, Virginia became operational in early summer of 1976. This facility is a joint effort by NASA-Lewis and NASA-Langley to advance the technology for heating and cooling of office buildings with solar energy. Its purposes are to (1) test system components which include high-performing collectors, (2) test performance of complete solar heating and cooling system, (3) investigate component interactions and (4) investigate durability, maintenance and reliability of components. The SBTF consists of a 50,000 square foot office building modified to accept solar heated water for operation of an absorption air conditioner and for the baseboard heating system. A 12,666 square foot solar collector field with a 30,000 gallon storage tank provides the solar heated water. A description of the system and the collectors selected is given here, along with the objectives, test approach, expected system performance and some preliminary results.

Dance and Music in "Gangnam Style": How Dance Observation Affects Meter Perception.

Lee, Kyung Myun; Barrett, Karen Chan; Kim, Yeonhwa; Lim, Yeoeun; Lee, Kyogu

2015-01-01

Dance and music often co-occur as evidenced when viewing choreographed dances or singers moving while performing. This study investigated how the viewing of dance motions shapes sound perception. Previous research has shown that dance reflects the temporal structure of its accompanying music, communicating musical meter (i.e. a hierarchical organization of beats) via coordinated movement patterns that indicate where strong and weak beats occur. Experiments here investigated the effects of dance cues on meter perception, hypothesizing that dance could embody the musical meter, thereby shaping participant reaction times (RTs) to sound targets occurring at different metrical positions.In experiment 1, participants viewed a video with dance choreography indicating 4/4 meter (dance condition) or a series of color changes repeated in sequences of four to indicate 4/4 meter (picture condition). A sound track accompanied these videos and participants reacted to timbre targets at different metrical positions. Participants had the slowest RT's at the strongest beats in the dance condition only. In experiment 2, participants viewed the choreography of the horse-riding dance from Psy's "Gangnam Style" in order to examine how a familiar dance might affect meter perception. Moreover, participants in this experiment were divided into a group with experience dancing this choreography and a group without experience. Results again showed slower RTs to stronger metrical positions and the group with experience demonstrated a more refined perception of metrical hierarchy. Results likely stem from the temporally selective division of attention between auditory and visual domains. This study has implications for understanding: 1) the impact of splitting attention among different sensory modalities, and 2) the impact of embodiment, on perception of musical meter. Viewing dance may interfere with sound processing, particularly at critical metrical positions, but embodied familiarity with

The architectural integration of thermal solar collectors into buildings is often limited by their black color, and the visibility of tubes and corrugations of the absorber sheets. A certain freedom in color choice would be desirable, but the colored appearance should not cause an excessive degradation of the collector efficiency. Multilayered thin film interference filters on the collector glazing can produce a colored reflection, hiding the corrugated metal sheet, while transmitting the non-reflected radiation entirely to the absorber. These interference filters are designed and optimized by numerical simulation, and are manufactured by sol-gel dip-coating or magnetron sputtering. The novel colored glazed solar collectors will be ideally suited for architectural integration into buildings, e.g. as solar active glass facades. Due to the tunability of the refractive index, nanostructured materials such as SiO{sub 2}:TiO{sub 2} composites and porous SiO{sub 2} are very useful for application in multilayer interference stacks. Novel quaternary Mg-F-Si-O films exhibit a surprisingly low refractive index and are therefore promising candidates for highly transparent coatings on solar collector glazing. The nanostructure of these thin films is studied by transmission electron microscopy, while the optical constants are measured precisely by ellipsometry. For a convincing demonstration, sufficiently large samples of high quality are imperatively needed. The fabrication of nanocomposite SiO{sub 2}:TiO{sub 2} films has been demonstrated by sol-gel dip-coating of A4-sized glass panes. The produced coatings exhibit a colored reflection in combination with a high solar transmittance, a homogenous appearance, and are free of visible defects. Film hardening by UV exposure will result in speeding up the sol-gel process and saving energy, thereby reducing costs significantly. The infrastructure for UV-curing has been established. A UV C radiation source can now be attached to the

The 1.6 m resolution DEM has been processed into global radiation input, solar energy output and production....... The continuous assessment of solar electricity generation potentials by marginal costs, ownership and plant type presented in the paper may be used for defining long term policies for the development of photovoltaic energy, as well as political instruments such as a multi-tier feed-in tariff....

Nanostructured Mesoporous Titanium Dioxide Thin Film Prepared by Sol-Gel Method for Dye-Sensitized Solar Cell

2011-01-01

Full Text Available Titanium dioxide (TiO2 paste was prepared by sol-gel and hydrothermal method with various precursors. Nanostructured mesoporous TiO2 thin-film back electrode was fabricated from the nanoparticle colloidal paste, and its performance was compared with that made of commercial P25 TiO2. The best performance was demonstrated by the DSSC having a 16 μm-thick TTIP-TiO2 back electrode, which gave a solar energy conversion efficiency of 6.03%. The ability of stong adhesion on ITO conducting glass substrate and the high surface area are considered important characteristics of TiO2 thin film. The results show that a thin film with good adhesion can be made from the prepared colloidal paste as a result of alleviating the possibility of electron transfer loss. One can control the colloidal particle size from sol-gel method. Therefore, by optimizing the preparation conditions, TiO2 paste with nanoparticle and narrow diameter distribution was obtained.

Project Outpost is a manned Earth-Sol/Mars-Sol platform that enables permanent occupation in deep space. In order to develop the program elements for this complex mission, Project Outpost will rely primarily on existing/nearterm technology and hardware for the construction of its components. For the purposes of this study, four mission requirements are considered: 1. Outpost - Man's 1st purpose-produced effort of space engineering, in which astructure is developed/constructed in an environment completely alien to currentpractices for EVA guidelines. 2. Newton - a concept study developed at StarGate Research, for the development ofa modified Hohmann personnel orbital transport operating between Earth andMars. Newton would serve as the primary crew delivery apparatus throughrepeatable transfer scheduling for all Earth-Lpoint-Mars activities. Thispermanent "transit system" would establish the foundations for Solar systemcolonization. 3. Cruis - a concept study developed at StarGate Research, for the development of amodified Hohmann cargo orbital transport operating between Earth and Mars.Cruis would serve as the primary equipment delivery apparatus throughrepeatable transfer scheduling for all Earth-Lpoint-Mars activities. Thispermanent "transit system" would establish the foundations for Solar systemcolonization, and 4.

Full Text Available Dance – as a ritual, therapy, and leisure activity – has been known for thousands of years. Today, dance is increasingly used as therapy for cognitive and neurological disorders such as dementia and Parkinson’s disease. Surprisingly, the effects of dance training on the healthy young brain are not well understood despite the necessity of such information for planning successful clinical interventions. Therefore, this study examined actively performing, expert-level trained college students as a model of long-term exposure to dance training. To study the long-term effects of dance training on the human brain, we compared 20 young expert female Dancers with normal body mass index with 20 age- and education-matched Non-Dancers with respect to brain structure and function. We used diffusion tensor, morphometric, resting state and task-related functional MRI, a broad cognitive assessment, and objective measures of selected dance skill (Dance Central video game and a balance task. Dancers showed superior performance in the Dance Central video game and balance task, but showed no differences in cognitive abilities. We found little evidence for training-related differences in brain volume in Dancers. Dancers had lower anisotropy in the corticospinal tract. They also activated the action observation network (AON to greater extent than Non-Dancers when viewing dance sequences. Dancers showed altered functional connectivity of the AON, and of the general motor learning network. These functional connectivity differences were related to dance skill and balance and training-induced structural characteristics. Our findings have the potential to inform future study designs aiming to monitor dance training-induced plasticity in clinical populations.

Full Text Available This paper traces successful and unsuccessful attempts to shape the meanings of the video game Dance Dance Revolution, specifically with reference to what "dancing" means in this context, as the game moves between various interested parties - game developers, players, Internet forum participants, and other media producers. Drawing on Actor-Network Theory and the network analyses of Manuel Castells, the paper reconstructs the forces shaping players' stylistic decisions through an analysis of dance game machines and software, and of a single forum thread on DDRFreak.com, a major website in the dance game community. The paper asks who decides how DDR players dance and at what times? Are the decisions about play made in the development meeting, the arcade, competitions, online or around the home console? Globally, how do some regions or groups emerge as experts or leaders in play style? Analysis indicates that within the United States, Californian players from major cities dominate discussion, supported by the global flows of people, resources, and capital through the state. The dominant players support their stated norms for play through recourse to mainstream conceptions of masculinity, rap music and associated styles of dance.

Economic analysis of solar assisted absorption chiller for a commercial building

Science.gov (United States)

Antonyraj, Gnananesan

Dwindling fossil fuels coupled with changes in global climate intensified the drive to make use of renewable energy resources that have negligible impact on the environment. In this attempt, the industrial community produced various devices and systems to make use of solar energy for heating and cooling of building space as well as generate electric power. The most common components employed for collection of solar energy are the flat plate and evacuated tube collectors that produce hot water that can be employed for heating the building space. In order to cool the building, the absorption chiller is commonly employed that requires hot water at high temperatures for its operation. This thesis deals with economic analysis of solar collector and absorption cooling system to meet the building loads of a commercial building located in Chattanooga, Tennessee. Computer simulations are employed to predict the hourly building loads and performance of the flat plate and evacuated tube solar collectors using the hourly weather data. The key variables affecting the economic evaluation of such system are identified and the influence of these parameters is presented. The results of this investigation show that the flat plate solar collectors yield lower payback period compared to the evacuated tube collectors and economic incentives offered by the local and federal agencies play a major role in lowering the payback period.

Complete systems for utilizing solar energy both for hot water preparation and for space heating are available in the FRG today. However, solar technology is unlikely to prevail without governmental support since the plants are still too expensive although there is a principal positive attitude towards solar energy. More knowledge of the process of solar energy utilization is necessary both in the field of building laws, and for building enterprises, architects and planners, if this new form of energy is to succeed.

Project 'Colored solar collectors' - Annual report 2004

Energy Technology Data Exchange (ETDEWEB)

Schueler, A.; Chambrier, E. De; Roecker, Ch.; Scartezzini, J.-L.

2004-12-15

The architectural integration of thermal solar collectors into buildings is often limited by their black color, and the visibility of tubes and corrugations of the absorber sheets. A certain freedom in color choice would be desirable, but the colored appearance should not cause excessive performance degradation. Multilayered thin film interference filters on the collector glazing can produce a colored reflection, hiding the corrugated metal sheet, while transmitting the non-reflected radiation entirely to the absorber. These interference filters are designed and optimized by numerical simulation and shall be manufactured by the sol-gel dip-coating process. The proposed colored glazed solar collectors will be ideally suited for architectural integration into buildings, e.g. as solar active glass facades. The sol-gel fabrication of interference stacks of up to five layers of silicon and titanium oxide films could be demonstrated in the laboratory, in the first step on microscope slides. Optical measurements are used to determine film thicknesses and optical constants of the individual layers, and to measure color coordinates and solar transmission for the multilayer stacks. The solar transmission of such samples can be improved by titanium silicon mixed oxides, which could have been synthesized by the sol-gel method. Hereby the compatibility problems of the originally used solution have been solved, and the refractive index of the resulting mixed oxide can be perfectly controlled by tuning the atomic concentration ratio of silicon and titanium. One of the main technical risks is related to the fact that for a convincing demonstration of the idea high quality coatings are absolutely necessary. Therefore, visible defects induced during the dip-coating process by dust particles in the atmosphere or in the used solutions must be imperatively avoided, as well as thickness variations due to vibrations. After optimizing various aspects of sample preparation, processing and

Analysis of the waggle dance motion of honeybees for the design of a biomimetic honeybee robot.

Directory of Open Access Journals (Sweden)

Tim Landgraf

Full Text Available The honeybee dance "language" is one of the most popular examples of information transfer in the animal world. Today, more than 60 years after its discovery it still remains unknown how follower bees decode the information contained in the dance. In order to build a robotic honeybee that allows a deeper investigation of the communication process we have recorded hundreds of videos of waggle dances. In this paper we analyze the statistics of visually captured high-precision dance trajectories of European honeybees (Apis mellifera carnica. The trajectories were produced using a novel automatic tracking system and represent the most detailed honeybee dance motion information available. Although honeybee dances seem very variable, some properties turned out to be invariant. We use these properties as a minimal set of parameters that enables us to model the honeybee dance motion. We provide a detailed statistical description of various dance properties that have not been characterized before and discuss the role of particular dance components in the commmunication process.

WHEN PROSE DANCES AND DANCE WALKS

Directory of Open Access Journals (Sweden)

Ana Marques Gastão

2011-04-01

Full Text Available To Paul Valéry, prose follows the less action path, as in marching in a straight line, and poetry, as in dancing – in as much as it is a «system of acts» – it not only intends to go nowhere but it remains in its own realisation, creating its own purpose. Why then does his prose contain this commanded impulse, led by desire, and his poetry does not, since they are so often one and the same? In this essay, looking at works by Rainer Marie Rilke, Fernando Pessoa, António Vieira and Yvette K. Centeno, I develop the idea that, very often, to establish a distinction between genres can be impractical and useless, if one considers concepts such as march/walk and dance from a choreographic perspective. Even if it be a possible question and since it has nevertheless been the object of study by scholars of all times, why is it undertaken? Why can’t prose be danced to, and poetry marched to? Can the walking essence unconsciously dance?

China is the second largest country in energy consumption. More and more energy demand pressures cause the Chinese government to review its economy and energy policies in order to support the sustainable development. In China, the building sector amounts to 27.8% total energy consumption, which is only behind the industry sector. China has abundant solar energy resource, which is extensively applied to buildings. Therefore, solar energy utilization in buildings has become one of the most important issues to help China optimize the energy proportion, increasing energy efficiency and protecting the environment. Solar energy resource and its district distribution in China are introduced in detail in this paper, and the representative solar energy application to the building sector is highlighted as well. The solar energy utilization obstacles, especially policy disadvantages in building sector in China, are reviewed. Moreover, the application prospects of solar energy in building sector are presented in combination with the China economic and household industry growth

Exergoeconomic Assessment of Solar Absorption and Absorption–Compression Hybrid Refrigeration in Building Cooling

Directory of Open Access Journals (Sweden)

Yue Jing

2018-02-01

Full Text Available The paper mainly deals with the match of solar refrigeration, i.e., solar/natural gas-driven absorption chiller (SNGDAC, solar vapor compression–absorption integrated refrigeration system with parallel configuration (SVCAIRSPC, and solar absorption-subcooled compression hybrid cooling system (SASCHCS, and building cooling based on the exergoeconomics. Three types of building cooling are considered: Type 1 is the single-story building, type 2 includes the two-story and three-story buildings, and type 3 is the multi-story buildings. Besides this, two Chinese cities, Guangzhou and Turpan, are taken into account as well. The product cost flow rate is employed as the primary decision variable. The result exhibits that SNGDAC is considered as a suitable solution for type 1 buildings in Turpan, owing to its negligible natural gas consumption and lowest product cost flow rate. SVCAIRSPC is more applicable for type 2 buildings in Turpan because of its higher actual cooling capacity of absorption subsystem and lower fuel and product cost flow rate. Additionally, SASCHCS shows the most extensive cost-effectiveness, namely, its exergy destruction and product cost flow rate are both the lowest when used in all types of buildings in Guangzhou or type 3 buildings in Turpan. This paper is helpful to promote the application of solar cooling.

This document is the Final Report of the Solar Energy System Installed at the First Solar Heated Office Building, One Solar Place, Dallas, Texas. The Solar System was designed to provide 87 percent of the space heating needs, 100 percent of the potable hot water needs and is sized for future absorption cooling. The collection subsystem consists of 28 Solargenics, series 76, flat plate collectors with a total area of 1596 square feet. The solar loop circulates an ethylene glycol-water solution through the collectors into a hot water system heat exchanger. The hot water storage subsystem consists of a heat exchanger, two 2300 gallon concrete hot water storage tanks with built in heat exchangers and a back-up electric boiler. The domestic hot water subsystem sends hot water to the 10,200 square feet floor area office building hot water fixtures. The building cold water system provides make-up to the solar loop, the heating loop, and the hot water concrete storage tanks. The design, construction, cost analysis, operation and maintenance of the solar system are described. The system became operational July 11, 1979.

Comparative study of solar cooling systems with building-integrated solar collectors for use in sub-tropical regions like Hong Kong

Highlights: ► Performance of building-integrated solar collectors analyzed. ► Comparisons made with solar collectors installed on roof. ► Use of building-integrated solar collectors increased the total primary consumption. ► Reduction in the building load could not compensate drop in solar collector output. ► Building-integrated solar collectors only used when roof space insufficient. -- Abstract: The performance of solar cooling systems with building-integrated (BI) solar collectors was simulated and the results compared with those having the solar collectors installed conventionally on the roof based on the weather data in Hong Kong. Two types of solar collectors and the corresponding cooling systems, namely the flat-plate collectors for absorption refrigeration and the PV panels for DC-driven vapour compression refrigeration, were used in the analysis. It was found that in both cases, the adoption of BI solar collectors resulted in a lower solar fraction (SF) and consequently a higher primary energy consumption even though the zone loads were reduced. The reduction in SF was more pronounced in the peak load season when the solar radiation was nearly parallel to the solar collector surfaces during the daytimes, especially for those facing the south direction. Indeed, there were no outputs from the BI flat-plate collectors facing the south direction between May and July. The more severe deterioration in the system performance with the BI flat-plate type collectors made them technically infeasible in terms of the energy-saving potential. It was concluded that the use of BI solar collectors in solar cooling systems should be restricted only to situations where the availability of the roof was limited or insufficient when applied in sub-tropical regions like Hong Kong.

This article mainly uses the literature material law to carry on the detailed analysis to the sports dance constitution, elaborated in detail the sports dance artistic expression. The composition of sports dance elements; sports dance is a form of dance art show; sports dance through the dance art can be divided into three aspects, namely, form, music, shape of the expressive force. In this paper, the study will be more in-depth excavation of the cultural connotation of sports dance, and promote the development of sports dance can be more comprehensive. In 20s of last century, Chinese Sports Dance Association officially joined the International Sports Dance Association, which also makes our country’s sports dance and international exchange more frequent. However, due to China’s sports dance sports dance learning time is not long, while learning is influenced by Chinese traditional culture, the sports dance movements are too conservative, there is a very large gap and international enthusiasm, bold and unrestrained, the pursuit of individual sports dance in the dance style, music and performance hand. Sports dance originated from abroad, it is produced in the daily life of people in foreign countries. China’s domestic sports dance players in learning dance at the same time, the production and the connotation of dance is not very understanding, therefore, it is difficult to better reflect the emotional expression of sports dance. Although the sports dance is a kind of similar to the competitive projects, but it is also a kind of dance culture, and to constitute a force from the dance art show a detailed study, detailed mining playing officer of sports dance performance further, reducing China’s sports dance and international sports dance gap.

Smiljana Mandukic (1908-1992 Beginning of Modern Dance and Dance Expressionism in Europe

Full Text Available Smiljana Mandukić (1908-1992 a dancer, choreographer, and teacher, was among those dancers who pioneering the modern dance in Serbia. The beginning of the 20th century brought new forms of art as the old ones were not sufficient to express new feelings and experiences, in that era of rapid technological progress. Mandukic was educated as a dancer in interwar Vienna, so she happened to be at the centre of Central European expressionist dance, free dance, at the time of her formation as a dancer. Smiljana acquired dance knowledge from her teachers, famous dancers and choreographers, Gertrud Bodenwieser, who developed her own style of modern expressionist dance, known as “Bodenwieser Viennise Style”, and Grete Wiesenthal, who was a member of the corps de ballet of the Hofoper in Vienna (Vienna Court Opera Ballet. Both her teachers were the representatives of “Ausdrukstanz” or “Neur Tanz”, and were rejected formalism and virtuosity of classical dance in favour of more natural movements. Like her pair, Maga Magazinovic (1882-1968, who introduced expressionist dance in Serbia, established the first school of modern dance in 1910, and founded the first modern dance group consisted of female dancers, Mandukic advocated for the importance of dance in education of female population. In the traditional, patriarchal Serbian society, she opened the second school of modern dance in 1931, and was the first artist who established a professional group of modern dance. Her greatest achievement was the creation of “epic-patriotic choreodrama”. The main goal of this article is to confirm that Smiljana Mandukic’s pioneer work in establishing modern dance in Serbia was the part of the European expressionist modern dance movement of the equal importance and significance not only when considering the Western Balkans but the broader European context.

D. Regonini

2014-01-01

Full Text Available This work has focused on the investigation of a non-aqueous based sol-gel process to produce TiO2 based photoelectrodes for solar water splitting. In particular, the effect of the aging time of the sol and TiO2 film thickness on the photoelectrochemical properties of the photoanodes has been investigated. In order to achieve optimal performances (i.e., photocurrent density up to 570 µA/cm2 and IPCE of 26% at 300 nm, the sol needs to be aged for 3 to 6 h, before being dip-coated to produce the photoanodes. The importance of the aging time can also be appreciated from the optical properties of the TiO2 films; the absorbance threshold of the sol-gel aged for 3–6 h is slightly shifted towards longer wavelenghts in comparison to 0 h aging. Aging is necessary to build up a well-interconnected sol-gel network which finally leads to a photoelectrode with optimized light absorption and electron collection properties. This is also confirmed by the higher IPCE signal of aged photoelectrodes, especially below 340 nm. Among thicknesses considered, there is no apparent significant difference in the photoresponse (photocurrent density and IPCE of the TiO2 sol-gel films.

In an effort to encourage the design, construction, and marketing of moderately priced passive solar homes in Washington state, the Western Solar Utilization Network (Western SUN) recently sponsored the Washington Passive Solar Design/Build Competition. The competition drew an overwhelming response from designers and builders throughout Washington. Thermal performance of the designs was evaluated by a technical review committee, and final selections were made by the Competition Jury in accordance with the following criteria: perceived market acceptance, thermal performance, cost effectiveness, simplicity of design and operation, and completeness of the passive concept. Design contract awards totaling $50,000 were made available to winners in four categories, including single and multi-family, new and remodeled residences. In order to receive the award in its entirety, winning design/build teams are required to construct their design by April, 1983. As a result of the competition, a great deal was learned about the attitudes and knowledge of professionals and the general public regarding the use of solar energy in Washington state. Among the points that will be highlighted in this paper are the following: (1) a design/build competition is an effective vehicle for promoting solar energy among professionals in the housing community as well as the general public; (2) passive solar techniques can contribute significantly to the heating and cooling needs of residential housing throughout the state of Washington; (3) there is a great deal of interest and talent among the designers and builders of solar residences in Washington; and (4) follow-up activities, including the promotion of winning designs, the systematic collection of performance data, and identification of the major obstacles confronting designers and builders of solar homes, are critical to the success of the program in achieving both its short-term and long-term goals.

The Negro Dance

2016-12-01

Full Text Available Katherine Dunham’s The Negro Dance (1941 focuses on dances in the West Indies and on their similarities with North American dance forms rooted in African culture. Though backed up by the New Negro arguments of the time, it shows Dunham’s prominent elaboration of a dignified African-American art based on syncretic bodily practices, which anticipated theorizations in dance and cultural studies. By uniting a theoretical approach and performance ability, she also made methodological choices which, decades later, became standard practices in the field of dance anthropology. Moreover, she is now considered an ante litteram exponent of public or applied anthropology due to the fact that, by using various strategies, she managed to take anthropological knowledge out of the academic world and use it as an instrument for social transformation. The Negro Dance is introduced by Rossella Mazzaglia and followed by an afterword by Cristiana Natali and a biographical note by Marie-Christine Dunham Pratt.

Highlights: • Models of Solar thermal, Photovoltaic and Photovoltaic/thermal systems are developed. • Experiments are performed to validate the simulation results. • Annual performances of the three solar systems used in china are predicted. • Energy comparison between the three solar systems is analyzed. - Abstract: Buildings need energy including heat and electricity, and both of them can be provided by the solar systems. Solar thermal and photovoltaic systems absorb the solar energy and can supply the heat and electricity for buildings, respectively. However, for the urban residential buildings, the limited available area makes installation of the solar thermal collectors and photovoltaic modules together impossible. A hybrid photovoltaic/thermal system can simultaneously generate heat and electricity, which is deemed to be quite suitable for the urban residential buildings application. And yet, for a rural house of China, the available area for installation of the solar collectors is large but daily domestic hot water demand of a rural family is generally not exceeded 300 L. If only the hybrid photovoltaic/thermal collectors are installed on the whole available area, this will lead to an overproduction of the thermal energy, especially in summer. Moreover, buildings requiring for the heat and electricity are different in different regions and different seasons. In this paper, simulation models of the solar thermal, photovoltaic and hybrid photovoltaic/thermal systems are presented, and experiments are also performed to validate the simulation results. Using the validated models, performances of the three solar systems for residential applications were predicted.

Maraz, Aniko; Király, Orsolya; Urbán, Róbert; Griffiths, Mark D; Demetrovics, Zsolt

2015-01-01

Dancing is a popular form of physical exercise and studies have show that dancing can decrease anxiety, increase self-esteem, and improve psychological wellbeing. The aim of the current study was to explore the motivational basis of recreational social dancing and develop a new psychometric instrument to assess dancing motivation. The sample comprised 447 salsa and/or ballroom dancers (68% female; mean age 32.8 years) who completed an online survey. Eight motivational factors were identified via exploratory factor analysis and comprise a new Dance Motivation Inventory: Fitness, Mood Enhancement, Intimacy, Socialising, Trance, Mastery, Self-confidence and Escapism. Mood Enhancement was the strongest motivational factor for both males and females, although motives differed according to gender. Dancing intensity was predicted by three motivational factors: Mood Enhancement, Socialising, and Escapism. The eight dimensions identified cover possible motives for social recreational dancing, and the DMI proved to be a suitable measurement tool to assess these motives. The explored motives such as Mood Enhancement, Socialising and Escapism appear to be similar to those identified in other forms of behaviour such as drinking alcohol, exercise, gambling, and gaming.

No Simple Answers: A Holistic Approach to Issues Concerning Obesity and African Dance

Directory of Open Access Journals (Sweden)

Maxwell Xolani Rani

2017-02-01

Full Text Available Obesity is a growing health issue in South Africa that carries health risk detrimental to those living in Black townships. The author will argue that the use of South African traditional urban dances may be permissible option for replacing aerobics to help prevent and combat obesity. Christian missionaries, colonizers, Western education, urbanization, and apartheid have had negative impacts on South African traditional rural dances; however, South Africans who migrated to urban environments in the nineteenth and twentieth centuries transformed traditions under spatial and ideological constraints and created new South African traditional urban social dances. South African traditional urban social dances were created in urban environments, in slum yards and townships, and do not reach the same level of sacred ritual that South African traditional rural social dances do; thus, their use in Black townships to help fight obesity is a possibility that must be further researched. The use of South African traditional urban social dances may not only help prevent and reduce obesity, but also help build community, teach history, facilitate self-exploration in a holistic manner, and open doors for the youth of today to continue to transform traditional urban social dances to reflect the current realities they are experiencing in Black townships.

1995-08-01

A total of 98 dancing students from a collegiate school of dancing were studied through interview using a highly structured questionnaire to elicit details of the duration and intensity of dance training, menstrual patterns and musculoskeletal injuries sustained during training; 70 (72%) of these dancing students were eumenorrhoeic, while 15 (15.4%) had oligomenorrhoea. Thirteen (13.4%) either had amenorrhoea for over 90 days at the time of the study, or were on hormonal treatment because of amenorrhoea for over 3 months in the past 1 year. Those who were amenorrhoeic had longer training hours per week when compared with eumenorrhoeic and oligomenorrhoeic students. Both oligomenorrhoeic and amenorrhoeic students had a lower body mass index (18.25 kg/m2 and 18.26 kg/m2 versus 19.45 kg/m2, p dance, modern dance and musical theatre dance students as well as a significantly lower average body mass index. These data suggest a proportional correlation between menstrual dysfunction and proneness to musculoskeletal injuries in training, which could be explained by a hormonal mechanism.

Dance and sexuality: many moves.

Science.gov (United States)

Hanna, Judith Lynne

2010-03-01

This literature review of dance and sexual expression considers dance and religion, dance and sexuality as a source of power, manifestations of sexuality in Western theater art and social dance, plus ritual and non-Western social dance. Expressions of gender, sexual orientation, asexuality, ambiguity, and adult entertainment exotic dance are presented. Prominent concerns in the literature are the awareness, closeting, and denial of sexuality in dance; conflation of sexual expression and promiscuity of gender and sexuality, of nudity and sexuality, and of dancer intention and observer interpretation; and inspiration for infusing sexuality into dance. Numerous disciplines (American studies, anthropology, art history, comparative literature, criminology, cultural studies, communication, dance, drama, English, history, history of consciousness, journalism, law, performance studies, philosophy, planning, retail geography, psychology, social work, sociology, and theater arts) have explored dance and sexual expression, drawing upon the following concepts, which are not mutually exclusive: critical cultural theory, feminism, colonialism, Orientalism, postmodernism, poststructuralism, queer theory, and semiotics. Methods of inquiry include movement analysis, historical investigation, anthropological fieldwork, autoethnography, focus groups, surveys, and self-reflection or autobiographical narrative. Directions for future exploration are addressed.

Luminescent solar concentrators for building-integrated photovoltaics

Meinardi, Francesco; Bruni, Francesco; Brovelli, Sergio

2017-12-01

The transition to fully energetically sustainable architecture through the realization of so-called net zero-energy buildings is currently in progress in areas with low population density. However, this is not yet true in cities, where the cost of land for the installation of ground photovoltaic (PV) is prohibitively high and the rooftop space is too scarce to accommodate the PV modules necessary for sustaining the electrical requirements of tall buildings. Thus, new technologies are being investigated to integrate solar-harvesting devices into building façades in the form of PV windows or envelope elements. Luminescent solar concentrators (LSCs) are the most promising technology for semi-transparent, electrodeless PV glazing systems that can be integrated 'invisibly' into the built environment without detrimental effects to the aesthetics of the building or the quality of life of the inhabitants. After 40 years of research, recent breakthroughs in the realization of reabsorption-free emitters with broadband absorption have boosted the performance of LSCs to such a degree that they might be commercialized in the near future. In this Perspective, we explore the successful strategies that have allowed this change of pace, examining and comparing the different types of chromophores and waveguide materials, and discuss the issues that remain to be investigated for further progress.

2015-03-01

Dance is a universal form of human expression that offers a rich source for scientific study. Dance provides a unique opportunity to investigate brain plasticity and its interaction with behavior. Several studies have investigated the behavioral correlates of dance, but less is known about the brain basis of dance. Studies on dance observation suggest that long- and short-term dance training affect brain activity in the action observation and simulation networks. Despite methodological challenges, the feasibility of conducting neuroimaging while dancing has been demonstrated, and several brain regions have been implicated in dance execution. Preliminary work from our laboratory suggests that long-term dance training changes both gray and white matter structure. This article provides a critical summary of work investigating the neural correlates of dance. It covers functional neuroimaging studies of dance observation and performance as well as structural neuroimaging studies of expert dancers. To stimulate ongoing dialogue between dance and science, future directions in dance and brain research as well as implications are discussed. Research on the neuroscience of dance will lead to a better understanding of brain-behavior relationships and brain plasticity in experts and nonexperts and can be applied to the development of dance-based therapy programs. © 2014 New York Academy of Sciences.

Optimal topology of urban buildings for maximization of annual solar irradiation availability using a genetic algorithm

International Nuclear Information System (INIS)

Conceição António, Carlos A.; Monteiro, João Brasileiro; Afonso, Clito Félix

2014-01-01

An approach based on the optimal placement of buildings that favors the use of solar energy is proposed. By maximizing the area of exposure to incident solar irradiation on roofs and facades of buildings, improvements on the energy performance of the urban matrix are reached, contributing decisively to reduce dependence on other less environmentally friendly energy options. A mathematical model is proposed to optimize the annual solar irradiation availability where the placement of the buildings in urban environment favors the use of solar energy resource. Improvements on the solar energy potential of the urban grid are reached by maximizing the exposure of incident solar irradiation on roofs and facades of buildings. The proposed model considers predominant, the amount of direct solar radiation, omitting the components of the solar irradiation diffused and reflected. The dynamic interaction of buildings on exposure to sunlight is simulated aiming to evaluate the shadowing zones. The incident solar irradiation simulation and the dynamic shading model were integrated in an optimization approach implemented numerically. The search for optimal topological solutions for urban grid is based on a Genetic Algorithm. The objective is to generate optimal scenarios for the placement of buildings into the urban grid in the pre-design phase, which enhances the use of solar irradiation. - Highlights: • A mathematical model is proposed to optimize annual solar irradiation availability. • Maximization of incident solar irradiation on roofs and facades of buildings. • Dynamic interaction of buildings is simulated aiming to evaluate shadowing zones. • Search for optimal topological solutions for urban grid based on genetic algorithm. • Solutions are compared with the conventional configurations for urban grid

The Dancing Picture - The Ritual Dance of Native Australians

Directory of Open Access Journals (Sweden)

Monica Engelhart

1996-01-01

Full Text Available What kind of message does -or did — the dance convey to the Native Australians? Several types of communication can be distinguished in ritual dance. There is the narrative aspect, i.e., the dramatization of a myth, or of certain social relations, there is an aspect of explanation, i.e., the visual performance of significant conditions, an expressive aspect of worship, and even an aspect of transmission, as when the body of the dancer is thought to mediate divine power to the audience. When a dancer is considered possessed, the boundaries between his human identity and the divine are wiped out. This last aspect leads us to the second item of interest regarding the ritual dance in Australia, an issue that has been discussed at length regarding masked dancers in other societies, i.e., the question of whether the dancer is identified with the being represented, or merely performs as an actor in a play. In this discussion, the very technique of dancing may have some explanatory faculty, at least as long as we are dealing with Native Australian ritual dance.

Numerical investigation on thermal and fluid dynamic behaviors of solar chimney building systems

Full text: Buildings as big energy-consuming systems require large amount of energy to operate. Globally, buildings are responsible for approximately 40% of total world annual energy consumption. Sustainable buildings with renewable energy systems are trying to operate independently without consumption of conventional resources. Renewable energy is a significant approach to reduce resource consumption in sustainable building. A solar chimney is essentially divided into two parts, one - the solar air heater (collector) and second - the chimney. Two configurations of solar chimney are usually used: vertical solar chimney with vertical absorber geometry, and roof solar chimney. For vertical solar chimney, vertical glass is used to gain solar heat. Designing a solar chimney includes height, width and depth of cavity, type of glazing, type of absorber, and inclusion of insulation or thermal mass. Besides these system parameters, other factors such as the location, climate, and orientation can also affect its performance. In this paper a numerical investigation on a prototypal solar chimney system integrated in a south facade of a building is presented. The analysis is carried out on a three-dimensional model in air flow and the governing equations are given in terms of k-s turbulence model. Two geometrical configurations are investigated: 1) a channel with vertical parallel walls and 2) a channel with principal walls one vertical and the other inclined. The problem is solved by means of the commercial code Ansys-Fluent and the results are performed for a uniform wall heat flux on the vertical wall is equal to 300 and 600 W/m2. Results are given in terms of wall temperature distributions, air velocity and temperature fields and transversal profiles in order to evaluate the differences between the two base configurations and thermal and fluid dynamic behaviors. Further, the ground effect on thermal performances is examined. key words: mathematical modeling, solar chimney

Full Text Available The residential and commercial buildings demand increase with rapidly growing population. It leads to the vertical growth of the buildings and needs proper ventilation and day-lighting. The natural air ventilation system is not significantly works in conventional structure, so fans and air conditioners are mandatory to meet the proper ventilation and space conditioning. Globally building sector consumed largest energy and utmost consumed in heating, ventilation and space conditioning. This load can be reduced by application of solar chimney and integrated approaches in buildings for heating, ventilation and space conditioning. It is a sustainable approach for these applications in buildings. The authors are reviewed the concept, various method of evaluation, modelings and performance of solar chimney variables, applications and integrated approaches.

M. A. Rutkowski

2017-01-01

Full Text Available Solar systems are actively applied for heat supply of buildings in Europe. Usage of solar energy for heat supply of residential buildings is considered as rather efficient for the Republic of Belarus because total amount of direct and scattered solar radiation entering horizontal surface is equivalent to an average European index for the climate of Belarus. The paper analyzes an existing dependence on determination of solar system efficiency and proposes an amended formula for calculations while designing solar consumption systems and its legitimacy has been experimentally proved. A scheme of an experimental unit with explanations and a brief description for execution of experiments and main results of the completed investigations have been presented in the paper. Experiments have been carried out for solar systems with natural and forced coolant circulation. Attention has been paid to obtaining maximum possible temperature potential of the coolant during operation of the solar system within periods of high and low solar radiation intensity. Recommendations on practical application of solar systems for multi-storey residential buildings houses and mansion-type houses have been given in the paper. The paper presents technological principles of constructing “passive” solar heating devices. A comparison of traditionally applied and proposed alternative solar systems has been made for operational conditions in Belarus. The paper proposes a solar system for hot water supply of multi-storey buildings. The proposed system has found its first realization in the Republic while designing and constructing an energy-efficient demonstration 10-storey residential building in Mogilev within the framework of the UN Development Program project and Global Environment Fund “Improvement of energy efficiency for residential buildings in the Republic of Belarus”

In the current energy and environmental context it is imperative to implement systems based on renewable energy sources in order to reduce energy consumptions worldwide. Solar collectors are studied by many years and many researchers are focusing their attention in order to increase their efficiency and cost-effectiveness. Water solar collectors are often implemented for domestic hot water, heating or industrial processes and already have a place on the market. A promising system which is not yet widely known is represented by air solar collectors that could represent an efficient way to use the solar energy with a lower investment cost, a system that can be used in order to preheat the fresh air required for heating, drying, or to maintain a minimum temperature during winter. This paper presents a comprehensive literature review on air solar collectors used mainly in buildings, acting as a solar wall. Air solar collectors are roughly classified into two types: glazed and opaque. The present study comprises the solar collector classification, applications and their main parameters with a special focus on opaque solar collectors.

Full Text Available Jeffrey A Russell Division of Athletic Training, School of Applied Health Sciences and Wellness, Ohio University, Athens, OH, USA Abstract: Dancers are clearly athletes in the degree to which sophisticated physical capacities are required to perform at a high level. The standard complement of athletic attributes – muscular strength and endurance, anaerobic and aerobic energy utilization, speed, agility, coordination, motor control, and psychological readiness – all are essential to dance performance. In dance, as in any athletic activity, injuries are prevalent. This paper presents the research background of dance injuries, characteristics that distinguish dance and dancers from traditional sports and athletes, and research-based perspectives into how dance injuries can be reduced or prevented, including the factors of physical training, nutrition and rest, flooring, dancing en pointe, and specialized health care access for dancers. The review concludes by offering five essential components for those involved with caring for dancers that, when properly applied, will assist them in decreasing the likelihood of dance-related injury and ensuring that dancers receive optimum attention from the health care profession: (1 screening; (2 physical training; (3 nutrition and rest; (4 specialized dance health care; and (5 becoming acquainted with the nature of dance and dancers.

Passive solar design studies for non-domestic buildings. Case studies

Energy Technology Data Exchange (ETDEWEB)

1988-01-01

Of the passive solar designs reported, those for a light industrial building, a nurses hostel and a low rise office block were considered to be clearly cost effective. A retrofit study of a secondary school showed that incorporating passive solar measures into refurbishment could be cost effective. Designs for a sports hall and medium rise office block were considered to be only marginally cost effective and those for a hotel bedroom block and DIY superstore were judged not to be cost effective. The maximization of daylight penetration coupled with controls on the lighting systems produced the main energy saving. This orientation, built form, fenestration, window shape, perimeter (and overhead) daylight and atria were primary solar features. Direct gain considered in conjunction with building weight/response factor could contribute to a lesser degree. Trombe walls were shown to be generally uneconomic for this type of building and conservatories contributed to amenity value more than to savings.

The main objective of the research 'Zero Emission Buildings' ZEB is to develop products and solutions that provide buildings with zero greenhouse gas emissions associated with the production, operation and disposal. Can we make this happen must the building produce more energy than it needs to compensate for greenhouse gas emissions from the production of materials and the actual construction.To build up knowledge on experience with building integrated solar collectors in Norway, we have in this study made interviews with suppliers and manufacturers of solar collectors and some building owners. Since the focus is on climate shell, we have limited the study to include solar collectors to replace a part of the cladding or roofing. Construction upstairs roofing, outside facade or freestanding rack is not considered as building integrated in this context. The providers we have been in contact with appeals to slightly different parts of the market. This is reflected in the product's development, assembly and approach to the calculation of energy delivery. Overall, providers may offer a range of products suitable for both the professional and skilled carpenter, the interested 'man in the street' . The feedback we have received shows generally good experiences with the product and the installation. Because of the preliminary short operating periods of the investigated plants we have little data on energy supply from these plants. In summary, we can say that the knowledge and the products are available and it is up to use to use them.(Author)

A collaborative approach to communicating our amazing science. RAL Space at the Rutherford Appleton Lab, has initiated a unique collaboration with a team of award-winning performing artists with the aim of making space science research engaging and accessible to a wide audience. The collaboration has two distinct but connected strands one of which is the development of a contemporary dance work inspired by solar science and including images and data from the Space Physics Division of STFC RAL Space. The work has been commissioned by Sadler's Wells, one of the world's leading dance venues. It will be created by choreographer Alexander Whitley, video artist Tal Rosner and composers Ella Spira and Joel Cadbury and toured throughout the UK and internationally by the Alexander Whitley Dance Company (AWDC). The work will come about through collaboration with the work of the scientists of RAL Space and in particular the SOHO, CDS and STEREO missions, taking a particular interest in space weather. Choreographer Alexander Whitley and composers Ella Spira and Joel Cadbury will take their inspiration from the images and data that are produced by the solar science within RAL Space. Video artist Tal Rosner will use these spectacular images to create an atmospheric backdrop to accompany the work, bringing the beauty and wonder of space exploration to new audiences. Funding for the creation and touring of the work will be sought from Arts Council England, the British Council, partner organisations, trusts and foundations and private donors.The world premiere of the work will take place at Sadler's Wells in June 2017. It will then tour throughout the UK and internationally to theatres, science conferences and outreach venues with the aim of bringing the work of STFC RAL Space and the science behind solar science and space weather to new audiences. An education programme will combine concepts of choreography and space science aimed at young people in year 5 Key Stage 2 and be

Enhancement of Pleasure during Spontaneous Dance

Bernardi, Nicolò F.; Bellemare-Pepin, Antoine; Peretz, Isabelle

2017-01-01

Dancing emphasizes the motor expression of emotional experiences. The bodily expression of emotions can modulate the subjective experience of emotions, as when adopting emotion-specific postures and faces. Thus, dancing potentially offers a ground for emotional coping through emotional enhancement and regulation. Here we investigated the emotional responses to music in individuals without any prior dance training while they either freely danced or refrained from movement. Participants were also tested while imitating their own dance movements but in the absence of music as a control condition. Emotional ratings and cardio-respiratory measures were collected following each condition. Dance movements were recorded using motion capture. We found that emotional valence was increased specifically during spontaneous dance of groovy excerpts, compared to both still listening and motor imitation. Furthermore, parasympathetic-related heart rate variability (HRV) increased during dance compared to motor imitation. Nevertheless, subjective and physiological arousal increased during movement production, regardless of whether participants were dancing or imitating. Significant correlations were found between inter-individual differences in the emotions experienced during dance and whole-body acceleration profiles. The combination of movement and music during dance results in a distinct state characterized by acutely heightened pleasure, which is of potential interest for the use of dance in therapeutic settings.

Moe, Angela M

2014-01-01

Disempowering stereotypes plague public perceptions of older women's bodies, particularly within Western contemporary societies. Consequently, as women age, their bodies often become sources of shame, discomfort, and ridicule. Belly dance, as a form of recreative leisure, provides a unique and somewhat unexpected space for women to subvert such perceptions. Based on qualitative interviews with older American women who belly dance, this article examines the ways in which this form of recreation provides participants a means of (re)gaining mobility, (re)claiming social space, (re)building social support, and (re)defining what it means to be sensual later in life.

Full Text Available This article focuses on dance teaching in K-12 basic education from a reflection about the relevant adoption of elements from post 1950’s artistic movement on dancing creative processes in a dialogue with authors as Hassan (1985, Silva (2005, and Rengel (2008. On this perspective, changes on dance teaching and learning practical attitudes are considered, resulting from postmodern dance transformations, such as: the reformulation of body concept, the conception of dance as a democratic, collective, and creative process and the progressively narrowed bounds between school artistic approaches and art forms developed outside of the school environment

HCI challenges in Dance Education

Directory of Open Access Journals (Sweden)

2016-08-01

Full Text Available Dance learning is by nature multimodal, while dance practice presents a wide diversity across genres and contexts. Choreography and artistic contemporary dance performances have been using interactive technologies to support their creative process for several decades. Nevertheless the use of interactive technologies to support dance learning and education is still relatively immature and raises many challenges and interesting questions when it comes to choosing the appropriate human computer interaction methods. In this paper, we present the characteristics of dance teaching and learning in relation to interactive technology and we highlight the points/feedback that dance, as a field of mastering expressive movement, can bring to the design of whole-body interaction experiences.

A dance floor is often the only support of movements in dance. A dance floor surface that shows deficiencies, can result in acute injuries and chronic problems. Although the significance of an adequate dance floor is well known, there is still a lack of differentiated analyses of dance floor-related acute injuries. This study presents data on acute injuries exclusively caused by the dance floor. The data were obtained from standardized work accident reports from consultants (F 1000), documentary accident records from all Berlin theatres, a state ballet school (n=2,281), and case records from the Berlin State Accident Insurance (UKB) covering a period of 17 years. All analyses and descriptive statistics were conducted with Excel 2007 and SPSS 18. Dance floor surfaces were the causative factor in 12.8% of all accidents (n=291, female 183, male 108). Almost two thirds (62.6%) of all accidents in professional dancers happened on stage, and almost half (49.5%) occurred during performances. As for causative factors, 53.1% of the professional dancers (P) and 42.5% of the dance students (S) claimed that the floor had been "too slippery," with "getting stuck" or (tripping) as the second most common problem (P 18.4%, S 11.3%). Of the injured dancers, 41.8% were older than 30 years and can therefore be categorized as experienced. Dance floors play a significant role in the occurrence of acute injuries, even in experienced dancers. Performances on stage seem to be a particular risk. However, injury prevention measures should include all work locations (P) as well as non-dance-specific locations (S).

Psychophysiological responses to Salsa dance.

Directory of Open Access Journals (Sweden)

Laura Guidetti

Full Text Available Speculation exists whether dance provides physiological stimuli adequate to promote health and fitness benefits. Unfortunately, research to date has not addressed the affective and exertional responses to dance. These responses are of interest as positive affective and exertional responses experienced during physical activity may play an important role in predicting adherence. The present study aims to examine the psychophysiological responses of different Salsa dance styles. Ten pairs of dancers performed two different structured lessons of Salsa dance, including Typical Salsa and Rueda de Casino lessons, and a non-structured Salsa dance at a night club. Physiological responses (i.e., percent of heart rate reserve; %HRR were continuously assessed and perceived exertion and affective valence were rated every 15 min throughout the trials. %HRR responses differed between the Salsa dance styles (%HRR from 41.3 to 51.9%, and participants were dancing at intensities near their ventilatory threshold. Specifically, Typical Salsa lesson elicited lower %HRR responses than Rueda de Casino lesson (p 0.05. Surprisingly, exertional (from 8 to 11 and affective (from +3 to +5 responses were unaffected by Salsa dance styles (p > 0.05. These data support that different Salsa dance styles provide physiological stimuli adequate to promote health and fitness benefits, and perhaps more importantly, produce pleasurable experiences, which in turn might lead to an increase in adherence to Salsa dancing which likely provides exercise-like health benefits.

Dance is more than therapy: Qualitative analysis on therapeutic dancing classes for Parkinson's.

Science.gov (United States)

Rocha, Priscila A; Slade, Susan C; McClelland, Jodie; Morris, Meg E

2017-10-01

To understand the benefits and limitations of therapeutic dancing classes for people with Parkinson's disease (PD) and how best to design and implement classes. A stakeholder forum explored the opinions of 18 allied health clinicians, dance instructors, people with PD and caregivers. Data were thematically analysed and interpreted within a grounded theory framework. Four main themes were identified: (1) the need to consider the stage of disease progression when designing classes; (2) recognition that dance is more than just therapy; (3) the benefits of carefully selecting music to move by; (4) ways to design classes that are both feasible and engaging. These themes give rise to the theory that dancing classes can provide more than just therapeutic benefits. Dance affords creative expression and enables people to immerse themselves in the art-form, rather than focussing on the disease. The results highlight the benefits of enabling individuals with PD to be able to express themselves in a supportive environment that does not see them solely through the lens of Parkinson's. The feasibility of dance programs can be increased by educating dancing teachers about PD and the unique needs of people living with this condition. Well-structured dance classes can promote social-connectedness and joy, in addition to facilitating movement to music and physical activity. Consumers advised that careful planning of the classes and tailoring them to participant needs optimizes outcomes. Copyright © 2017 Elsevier Ltd. All rights reserved.

Using Solar Hot Water to Address Piping Heat Losses in Multifamily Buildings

Energy Technology Data Exchange (ETDEWEB)

Springer, David [Alliance for Residential Building Innovation, Davis, CA (United States); Seitzler, Matt [Alliance for Residential Building Innovation, Davis, CA (United States); Backman, Christine [Alliance for Residential Building Innovation, Davis, CA (United States); Weitzel, Elizabeth [Alliance for Residential Building Innovation, Davis, CA (United States)

2015-10-01

Solar thermal water heating is most cost effective when applied to multifamily buildings and some states offer incentives or other inducements to install them. However, typical solar water heating designs do not allow the solar generated heat to be applied to recirculation losses, only to reduce the amount of gas or electric energy needed for hot water that is delivered to the fixtures. For good reasons, hot water that is recirculated through the building is returned to the water heater, not to the solar storage tank. The project described in this report investigated the effectiveness of using automatic valves to divert water that is normally returned through the recirculation piping to the gas or electric water heater instead to the solar storage tank. The valves can be controlled so that the flow is only diverted when the returning water is cooler than the water in the solar storage tank.

International Nuclear Information System (INIS)

Feng, Chaoqing; Zheng, Hongfei; Wang, Rui; Yu, Xu; Su, Yuehong

2015-01-01

Highlights: • A novel transparent roof combines the solar PV/T/D system with green building design. • Novel photovoltaic-thermal roofing design can achieve excellent light control at noon. • The roof has no obvious influence on indoor light intensity in morning and afternoon. • Higher efficiency of solar energy utilization could be achieved with new roofing. - Abstract: A novel transparent roof which is made of solid CPC (Compound Parabolic Concentrator) PV/T/D (Photovoltaic/Thermal/Day lighting) system is presented. It combines the solar PV/T/D system with green building design. The PV/T/D system can achieve excellent light control at noon and adjust the thermal environment in the building, such that high efficiency utilization of solar energy could be achieved in modern architecture. This kind of roof can increase the visual comfort for building occupants; it can also avoid the building interior from overheating and dazzling at noon which is caused by direct sunlight through transparent roof. Optical simulation software is used to track the light path in different incidence angles. CFD (Computational Fluid Dynamics) simulation and steady state experiment have been taken to investigate the thermal characteristic of PV/T/D device. Finally, the PV/T/D experimental system was built; and the PV efficiency, light transmittance and air heating power of the system are tested under real sky conditions

Implementing Solar PV Projects on Historic Buildings and in Historic Districts

Energy Technology Data Exchange (ETDEWEB)

Kandt, A.; Hotchkiss, E.; Walker, A.; Buddenborg, J; Lindberg, J.

2011-09-01

Many municipalities, particularly in older communities of the United States, have a large amount of historic buildings and districts. In addition to preserving these historic assets, many municipalities have goals or legislative requirements to procure a certain amount of energy from renewable sources and to become more efficient in their energy use; often, these requirements do not exempt historic buildings. This paper details findings from a workshop held in Denver, Colorado, in June 2010 that brought together stakeholders from both the solar and historic preservation industries. Based on these findings, this paper identifies challenges and recommends solutions for developing solar photovoltaic (PV) projects on historic buildings and in historic districts in such a way as to not affect the characteristics that make a building eligible for historic status.

Genetic control of the honey bee (Apis mellifera) dance language: segregating dance forms in a backcrossed colony.

Science.gov (United States)

Johnson, R N; Oldroyd, B P; Barron, A B; Crozier, R H

2002-01-01

We studied the genetic control of the dance dialects that exist in the different subspecies of honey bees (Apis mellifera) by observing the variation in dance form observed in a backcross between two lines that showed widely different dance dialects. To do this we generated the reciprocal of the cross performed by Rinderer and Beaman (1995), thus producing phenotypic segregation of dance forms within a single colony rather than between colonies. Our results are consistent with Rinderer and Beaman (1995) in that inheritance of the transition point from round dancing --> waggle dancing is consistent with control by a single locus with more than one allele. That is, we found one dance type to be dominant in the F(1), and observed a 1:1 segregation of dance in a backcross involving the F(1) and the recessive parent. However, we found some minor differences in dance dialect inheritance, with the most significant being an apparent reversal of dominance between our cross (for us "black" is the dominant dialect) and that of Rinderer and Beaman (1995) (they report "yellow" to be the dominant dialect). We also found that our black bees do not perform a distinct sickle dance, whereas the black bees used by Rinderer and Beaman (1995) did perform such a dance. However, our difference in dominance need not contradict the results of Rinderer and Beaman (1995), as there is no evidence that body color and dominance for dance dialect are linked.

Design of an atrium for a passive-solar retrofit of an office buildings

Energy Technology Data Exchange (ETDEWEB)

Peterson, J.L.; Hunn, B.D.

1980-01-01

The Los Alamos Scientific Laboratory (LASL) has proposed to retrofit one of its administrative office buildings with a solar atrium. A 334 m/sup 2/ courtyard will be enclosed with a roof-mounted system of clerestory windows to maximize winter solar gain. This sunspace will thermally buffer the adjoining offices and also will preheat air supplied to the building's conventional heating, ventilating, and air-conditioning (HVAC) system. The use of the DOE-2 building energy analysis computer program in the design of the solar atrium is described. The results of a series of simulations are reported detailing the tradeoffs inherent in the selection of an optimal glazing area, the maintenance of acceptable comfort levels within the sunspace, and intergration of passive-solar devices with the conventional HVAC system. Potential energy savings are also discussed.

Solar cooling - comparative study between thermal and electrical use in industrial buildings

Science.gov (United States)

Badea, N.; Badea, G. V.; Epureanu, A.; Frumuşanu, G.

2016-08-01

The increase in the share of renewable energy sources together with the emphasis on the need for energy security bring to a spotlight the field of trigeneration autonomous microsystems, as a solution to cover the energy consumptions, not only for isolated industrial buildings, but also for industrial buildings located in urban areas. The use of solar energy for cooling has been taken into account to offer a cooling comfort in the building. Cooling and air- conditioned production are current applications promoting the use of solar energy technologies. Solar cooling systems can be classified, depending on the used energy, in electrical systems using mechanical compression chillers and systems using thermal compression by absorption or adsorption. This comparative study presents the main strengths and weaknesses of solar cooling obtained: i) through the transformation of heat resulted from thermal solar panels combined with adsorption chillers, and ii) through the multiple conversion of electricity - photovoltaic panels - battery - inverter - combined with mechanical compression chillers. Both solutions are analyzed from the standpoints of energy efficiency, dynamic performances (demand response), and costs sizes. At the end of the paper, experimental results obtained in the climatic condition of Galafi city, Romania, are presented.

Evaluating solar irradiance over facades in high building cities, based on LiDAR technology

International Nuclear Information System (INIS)

Martínez-Rubio, A.; Sanz-Adan, F.; Santamaría-Peña, J.; Martínez, Araceli

2016-01-01

Highlights: • A method for evaluating solar irradiance over façades in building cities with mutual shading. • It calculates irradiance curves in all building façades, using LiDAR and irradiance information. • Solar irradiation maps of the city buildings are really important for urban planning. • It allows to selection BIPV elements depending of the irradiation in each façade point. • The model can be extrapolated to all the building envelope. - Abstract: Arranging a solar irradiation map of the buildings of a city is a valuable tool for sustainable urban planning in regard to non-carbonized criteria in important applications. Such applications may include: selection of materials for the building envelope and insulation according to the irradiation received at each point; monitoring the installation of photovoltaic systems to ensure that they are located in the optimal irradiance zones; or building restoration to improve the energy efficiency and electric generation. The proposed method enables to estimate the incidence of the solar irradiance as well as to visualize the effect it produces in every region of the buildings that compose the urban area of a city. The process includes the use of Laser Imaging Detection and Ranging (LiDAR) information along with 5-min horizontal irradiance data. This developed algorithm has been verified through being applied to different building envelopes distributed in different geographical areas. The results demonstrate a satisfied performance which makes that the methodology can be extrapolated to any city where the LiDAR Data and irradiance information are available, permitting an accurate analysis of the solar irradiance over the building envelopes. The algorithm succeeds in obtaining a map of solar radiation captured by the envelope of any urban building that estimates the photovoltaic power generation depending on the geographic location and on the influence of shading caused by adjacent buildings.

Stein, Cynthia J; Tyson, Kesley D; Johnson, Victor M; Popoli, David M; d'Hemecourt, Pierre A; Micheli, Lyle J

2013-12-01

Irish dance is growing in popularity and competitiveness; however, very little research has focused specifically on this genre of dance. The purpose of this study was to analyze the types of dance injuries incurred by Irish dancers. A chart review was performed to identify all injuries associated with Irish dance seen in the sports medicine or orthopaedic clinics at the investigators' hospital over an 11-year period. "Injury" was defined as any dance-related pain or disorder that led to evaluation in the clinics. Survey data were also collected from study participants. Ultimately, 255 patients from over 30 different schools of dance were seen with injuries directly related (726 clinic visits) or partially related (199 visits) to Irish dance. Participants ranged in age from 4 to 47, with 95% (243/255) under the age of 19. These 255 patients received 437 diagnoses. Almost 80% of the injuries (348/437) were attributable to overuse, and 20.4% were acute and traumatic injuries (89/437). Ninety-five percent (95.9%) of injuries involved the hip or lower extremity. The most common sites were the foot (33.2%), ankle (22.7%), knee (19.7%), and hip (14.4%). Typical diagnoses were tendon injury (13.3%), apophysitis (11.4%), patellofemoral pain and instability (10.8%), stress injury (10.1%), and muscle injury (7.8%). The majority of traumatic injuries were seen in clinic within 3 weeks, but less than a quarter of overuse injuries were seen that quickly. The most common treatment, prescribed to 84.3% of patients, was physical therapy and home exercises, and the majority of dancers (64.3%) were able to return to full dance activity after injury.

The evolution of dance.

Science.gov (United States)

Laland, Kevin; Wilkins, Clive; Clayton, Nicky

2016-01-11

Evidence from multiple sources reveals a surprising link between imitation and dance. As in the classical correspondence problem central to imitation research, dance requires mapping across sensory modalities and the integration of visual and auditory inputs with motor outputs. Recent research in comparative psychology supports this association, in that entrainment to a musical beat is almost exclusively observed in animals capable of vocal or motor imitation. Dance has representational properties that rely on the dancers' ability to imitate particular people, animals or events, as well as the audience's ability to recognize these correspondences. Imitation also plays a central role in learning to dance and the acquisition of the long sequences of choreographed movements are dependent on social learning. These and other lines of evidence suggest that dancing may only be possible for humans because its performance exploits existing neural circuitry employed in imitation. Copyright © 2016 Elsevier Ltd.

Kolosov, Alexander; Chudinov, Dmitry; Yaremenko, Sergey

2018-03-01

Nowadays, the renovation program is being implemented in the megapolises of Russia. Innovative high-rise buildings are built instead of morally and physically obsolete houses, where non-traditional renewable energy sources are used to the fullest extent, under the effect of which they are located. The possibility to use solar systems with variation of their design parameters is considered. It is established that solar systems have high technical potential. The share of heat load, that is provided by using solar energy, varies from 4 to 84% depending on the time of the year. Economic indicators restrain the use of such panels. The payback period is about 8 years at the current cost for thermal energy.

Between the Dance Studio and the Social Dance Floor: On Solidarity and Practices of Mutuality in Swing Dance Communities

Directory of Open Access Journals (Sweden)

Boštjan Kravanja

2014-07-01

Full Text Available This article discusses the dynamics of actualization of solidarity and hierarchical relations in contemporary swing dance communities. It shows how these communities are based on a specific solidarity ideology, at least it terms of dealing with processes of their institutionalization, commercialization and establishing of formal dance hierarchies. However, when we take into view the swing dancers themselves, diverse practices of mutuality become evident. In contrast to the formal solidarity discourses and practices, the latter are much more heterogeneous and as such more interesting for anthropological discussion, for they establish solidarity and hierarchical relations apart from wider mobilization movements of the swing dance industry, and many of them implicitly resist institutionalization. The thesis arising from this case study is that the practices of mutuality are not always in complementary relation with discourses of solidarity. On the contrary, they often bypass the major solidarity flows and, paradoxically, contribute most efficiently to the actual solidarity of vital parts of the swing communities. The author discusses the subject on the basis of six years of active participation in different Slovene swing dance scenes and occasional presence at international swing dance events in different European cities.

Lapum, Jennifer L; Bar, Rachel J

2016-03-01

The movement and music associated with dance plays an important role in many individuals' lives and can become imprinted upon the body and mind. Dance is thus closely associated with memory because of these deep connections. Without conscious thought, dance has the potential to be initiated as individuals age. In the current article, the authors share narrative reflections about their experiences with, and the potential of, dance as an intervention for aging populations diagnosed with dementia-related diseases. They draw upon their experiences in working with the aging population and a dance program currently being developed by Canada's National Ballet School and Baycrest Health Sciences for individuals with dementia-related diseases in long-term care. The current article is structured as dialogue between the authors because it mimics dance as a dialogical encounter between movement and music, and/or between individuals.

Lesté, A; Rust, J

1984-06-01

The study investigated the effects of modern dance on anxiety. State anxiety was assessed before and after a 3-mo. education programme, using the Spielberger State-Trait Anxiety Inventory. The target group followed a class in modern dance. Control groups were (1) a physical education group to control for the effects of exercise, (2) a music group to control for aesthetic sensitivity training, and (3) a mathematics group. Several concomitant variables were measured: age, sex, attitude towards dance, and previous experience in sport, dance, and relaxation. Dance training significantly reduced anxiety, but no control activities did so. Examination of the concomitant variables showed that the result could not be accounted for by any obvious artifacts.

As nursing and health care practice enter the new Millennium, practitioners are increasingly urged to pay attention to evidenced based practice to justify what they do. Yet the truth is, that within the caring dance, practitioners need to connect with more ancient sources of wisdom. Failure to do so leads to a life out of balance and a failure to dance well and fulfil the fundamental role of being a nurse. The paper draws exclusively on the work of Blackwolf and Gina Jones, as an example of such ancient wisdom to inform and inspire the caring dance.

Increasingly good evidence emerges of the positive benefits of sport, exercise, music, dance and mindfulness-based stress reduction in the building of the mental strength necessary to overcome these troubled times. The integrity of our mental health is challenged as each of us is threatened by calamity. Groups and teams, community’s and clubs are effective means of collective support. And positive mental health skills and attitudes are associated with greater individual wellbeing and with longer and happier life. Mental health is the resource which will empower recovery in us and in our economy. Modern neuroscience is proving the centrality of the brain in positive wellbeing. The evidence shows that human recovery is enhanced by music and dance and by song and by exercise, and by mindfulness. That is why we mustn’t wait any longer to lead mentally healthy lives. In Ireland we must not wait any longer to be happy.\\r\

We searched databases including CINHAL (1982–2015, Medline (1922–2015, Scopus (1996–2015, Web of Science (2002–2015, Embase (2007–2015, PEDro (1999–2015 and the Cochrane Library (1996–2015. The key words were: Parkinson's disease, Parkinson*, Parkinsonism, dance, dance therapy, dance genres, safety, feasibility, and quality of life. Two independent investigators reviewed the texts. Only randomized controlled trials, quasirandomized controlled trials, and case series studies were included. There was emerging evidence that therapeutic dance can be safe and feasible for people with mild to moderately severe PD, with beneficial effects on walking, freezing of gait, and health related quality of life.

2010-01-01

On Sunday 29 August, the Bulgarian folklore dance group Rhythm visited CERN. After their visit to the ATLAS visitor centre and the SM18 hall, they performed a show in the Pump Room, introducing CERN people to the musical traditions of their country.   The visit of the Bulgarian dance group was organized by Zornitsa Zaharieva, a member of the Beams Department, and Svejina Dimitrova, Director of the Varna Astronomical Observatory. “The students were enthusiastic about the opportunity to visit CERN”, says Zornitsa. “The idea of the performance came from the dance group itself, who wanted to express their gratitude for being given this chance”. The group, comprising around 25 children aged between 11 and 16 from the city of Varna, was hosted by the CERN Dancing Club. For their show, the young dancers, choreographed by Tashka Pavlova, performed traditional dances and songs from different Bulgarian regions. “As a member of the CERN Dancing Club com...

Poikonen, Hanna; Toiviainen, Petri; Tervaniemi, Mari

2018-03-01

When watching performing arts, a wide and complex network of brain processes emerge. These processes can be shaped by professional expertise. When compared to laymen, dancers have enhanced processes in observation of short dance movement and listening to music. But how do the cortical processes differ in musicians and dancers when watching an audio-visual dance performance? In our study, we presented the participants long excerpts from the contemporary dance choreography of Carmen. During multimodal movement of a dancer, theta phase synchrony over the fronto-central electrodes was stronger in dancers when compared to musicians and laymen. In addition, alpha synchrony was decreased in all groups during large rapid movement when compared to nearly motionless parts of the choreography. Our results suggest an enhanced cortical communication in dancers when watching dance and, further, that this enhancement is rather related to multimodal, cognitive and emotional processes than to simple observation of dance movement. © 2018 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

Verbal Auditory Cueing of Improvisational Dance: A Proposed Method for Training Agency in Parkinson’s Disease

Science.gov (United States)

Batson, Glenna; Hugenschmidt, Christina E.; Soriano, Christina T.

2016-01-01

Dance is a non-pharmacological intervention that helps maintain functional independence and quality of life in people with Parkinson’s disease (PPD). Results from controlled studies on group-delivered dance for people with mild-to-moderate stage Parkinson’s have shown statistically and clinically significant improvements in gait, balance, and psychosocial factors. Tested interventions include non-partnered dance forms (ballet and modern dance) and partnered (tango). In all of these dance forms, specific movement patterns initially are learned through repetition and performed in time-to-music. Once the basic steps are mastered, students may be encouraged to improvise on the learned steps as they perform them in rhythm with the music. Here, we summarize a method of teaching improvisational dance that advances previous reported benefits of dance for people with Parkinson’s disease (PD). The method relies primarily on improvisational verbal auditory cueing with less emphasis on directed movement instruction. This method builds on the idea that daily living requires flexible, adaptive responses to real-life challenges. In PD, movement disorders not only limit mobility but also impair spontaneity of thought and action. Dance improvisation demands open and immediate interpretation of verbally delivered movement cues, potentially fostering the formation of spontaneous movement strategies. Here, we present an introduction to a proposed method, detailing its methodological specifics, and pointing to future directions. The viewpoint advances an embodied cognitive approach that has eco-validity in helping PPD meet the changing demands of daily living. PMID:26925029

Sustainable pathways of land use for energy are necessary to mitigate climate change and limit conversion of finite land resources needed for conservation and food production. Large, commercial buildings (LCBs) are increasing in size and number throughout the United States (US) and may serve as suitable recipient environments for photovoltaic (PV) solar energy infrastructure that may support a low carbon, low land footprint energy transition. In this study, we identified, characterized, and evaluated the technical potential of the largest, commercial building rooftops (i.e., exceeding 110,000 m2) and their associated parking lots in the US for PV solar energy systems using Aurora, a cloud-based solar optimization platform. We also performed a case study of building-specific electricity generation: electricity consumption balance. Further, we quantified the environmental co-benefit of land sparing and associated avoided emissions (t-CO2-eq) conferred under the counterfactual scenario that solar development would otherwise proceed as a ground-mounted, utility-scale PV installation of equal nominal capacity. We identified and mapped 37 LCBs (by rooftop area) across 18 states in the US, spanning from as far north as the state of Minnesota to as far south as Florida. Rooftop footprints range from 427,297 to 113,689 m2 and have a cumulative surface area of 99.8 million ft2. We characterize the LCBs as either: distribution/warehouse, factory, shopping center, or administrative office/facility. Three of the 37 LCBs currently support rooftop PV and the numbers of associated, detached buildings number up to 38. This study elucidates the extent to which LCBs and their respective parking lots can serve as suitable sites for PV solar energy generation. Lastly, this study demonstrates research-based applications of the Aurora energy modeling platform and informs decision-making focused on redirecting energy development towards human-modified landscapes to prioritize land use for

MUNI Ways and Structures Building Integrated Solar Membrane Project

Energy Technology Data Exchange (ETDEWEB)

Smith, Randall

2014-07-03

The initial goal of the MUNI Ways and Structures Building Integrated Solar Membrane Installation Project was for the City and County of San Francisco (CCSF) to gain experience using the integrated higher efficiency solar photovoltaic (PV) single-ply membrane product, as it differs from the conventional, low efficiency, thin-film PV products, to determine the feasibility of success of larger deployment. As several of CCSF’s municipal rooftops are constrained with respect to weight restrictions, staff of the Energy Generation Group of the San Francisco Public Utilities Commission (SFPUC) proposed to install a solar PV system using single-ply membrane The installation of the 100 kW (DC-STC) lightweight photo voltaic (PV) system at the MUNI Ways and Structures Center (700 Pennsylvania Ave., San Francisco) is a continuation of the commitment of the City and County of San Francisco (CCSF) to increase the pace of municipal solar development, and serve its municipal facilities with clean renewable energy. The fourteen (14) solar photovoltaic systems that have already been installed at CCSF municipal facilities are assisting in the reduction of fossil-fuel use, and reduction of greenhouse gases from fossil combustion. The MUNI Ways & Structures Center roof has a relatively low weight-bearing capacity (3.25 pounds per square foot) and use of traditional crystalline panels was therefore rejected. Consequently it was decided to use the best available highest efficiency Building-Integrated PV (BIPV) technology, with consideration for reliability and experience of the manufacturer which can meet the low weight-bearing capacity criteria. The original goal of the project was to provide an opportunity to monitor the results of the BIPV technology and compare these results to other City and County of San Francisco installed PV systems. The MUNI Ways and Structures Center was acquired from the Cookson Doors Company, which had run the Center for many decades. The building was

Solar energy modelling is increasingly popular, important, and economic significant in solving energy crisis for big cities. It is a clean and renewable resource of energy that can be utilized to accommodate individual or group of buildings electrical power as well as for indoor heating. Implementing photovoltaic system (PV) in urban areas is one of the best options to solve power crisis over expansion of urban and the growth of population. However, as the spaces for solar panel installation in cities are getting limited nowadays, the available strategic options are only at the rooftop and façade of the building. Thus, accurate information and selecting building with the highest potential solar energy amount collected is essential in energy planning, environmental conservation, and sustainable development of the city. Estimating the solar energy/radiation from rooftop and facade are indeed having a limitation - the shadows from other neighbouring buildings. The implementation of this solar estimation project for Istanbul uses CityGML LoD2-LoD3. The model and analyses were carried out using Unity 3D Game engine with development of several customized tools and functionalities. The results show the estimation of potential solar energy received for the whole area per day, week, month and year thus decision for installing the solar panel could be made. We strongly believe the Unity game engine platform could be utilized for near future 3D mapping visualization purposes.

As the number of people diagnosed with Parkinson's disease increases, there is a need to develop initiatives that promote health and wellbeing and support self-management. Additionally, as exercise may slow physical decline, there is a need to develop methods that facilitate greater engagement with community-based exercise. The aim of this study is to examine the needs of (1) people with Parkinson's disease and (2) set dancing teachers to enable the development of participant-centred community set dance classes. A mixed methods study design was used. Two consensus group discussions using nominal group technique were held to (1) identify factors pertaining to the needs of people with Parkinson's disease from a set dance class and (2) the educational needs of set dancing teachers to enable them to teach set dancing to people with Parkinson's disease. Group discussions began with silent generation of ideas. A round-robin discussion and grouping of ideas into broader topic areas followed. Finally, participants ranked, by order of priority (1-5), the topic areas developed. Final data analysis involved summation of participants' ranking scores for each topic area. Rich information on the needs of people with Parkinson's disease from a dance class and the educational guidance sought by set dancing teachers was gathered. Topic areas developed include "teaching method" for set dances and "class environment". Accessing community exercise programmes is important for this population. The results of this study will inform the development of an educational resource on Parkinson's disease for set dancing teachers. This resource may facilitate a larger number of teachers to establish sustainable community set dancing classes for people with Parkinson's disease. Copyright © 2016 Elsevier Ltd.

We present a comparison of solar thermal and solar electric cooling for a typical small office building exposed to two different European climates (Freiburg and Madrid). The investigation is based on load series for heating and cooling obtained previously from annual building simulations in TRNSYS. A conventional compression chiller is used as the reference system against which the solar options are evaluated with respect to primary energy savings and additional cost. A parametric study on collector and storage size is carried out for the solar thermal system to reach achieve the minimal cost per unit of primary energy saved. The simulated solar electric system consists of the reference system, equipped with a grid connected photovoltaic module, which can be varied in size. For cost comparison of the two systems, the electric grid is assumed to function as a cost-free storage. A method to include macroeconomic effects in the comparison is presented and discussed. Within the system parameters and assumptions used here, the grid coupled PV system leads to lower costs of primary energy savings than the solar thermal system at both locations. The presumed macroeconomic advantages of the solar thermal system, due to the non-usage of energy during peak demand, can be confirmed for Madrid. (author)

To understand why individuals with Parkinson's disease (PD) participate in a community-based therapeutic dance program and to explore its influence on perceived physical, social and emotional well-being of participants. A qualitative descriptive design was employed using one-on-one semi-structured interviews. Individuals with PD who participated in the Dancing with Parkinson's program were recruited from two locations. Interviews were audio-recorded, transcribed, de-identified and then placed into NVivo 10 software for analysis. A content analysis approach was used with an inductive analysis method to generate a coding scheme. Group discussion facilitated development of overarching themes. Ten participants' responses revealed that the dance program allows for self-improvement and regaining identity through disease self-management. Positive influences of socialization arose through the class, decreasing isolation and improving quality of life. Participants communicate through music and dance to enhance connection with others. Dancing with Parkinson's classes allow for re-development of the social self, which can increase sense of enjoyment in life. Dance programs provide opportunities for social interaction, non-verbal communication and self-improvement, reestablishing self-identity and a sense of usefulness. This study provides unique insight into the experience of participating in a dance program from the perspective of individuals with PD. Implications for rehabilitation Dance is emerging as a strategy to address the physical and psychosocial effects of Parkinson's disease (PD), but little is known regarding participants' perceptions of community-based therapeutic dance programs for PD. This study found that Dancing with Parkinson's (DWP) facilitated an improvement in social participation, resulting in decreased isolation and improved quality of life. Participation in the DWP program can facilitate a positive change in perspective and attitude toward a PD

Maes, Pieter-Jan; Amelynck, Denis; Leman, Marc

2012-12-01

In this article, a computational platform is presented, entitled "Dance-the-Music", that can be used in a dance educational context to explore and learn the basics of dance steps. By introducing a method based on spatiotemporal motion templates, the platform facilitates to train basic step models from sequentially repeated dance figures performed by a dance teacher. Movements are captured with an optical motion capture system. The teachers' models can be visualized from a first-person perspective to instruct students how to perform the specific dance steps in the correct manner. Moreover, recognition algorithms-based on a template matching method-can determine the quality of a student's performance in real time by means of multimodal monitoring techniques. The results of an evaluation study suggest that the Dance-the-Music is effective in helping dance students to master the basics of dance figures.

Solar radiation for buildings application: comparing reduced data set for mediterranean sites

La Gennusa, M.; Rizzo, G.; Scaccianoce, G.; Sorrentino, G.

2006-01-01

A growing diffusion of computer programs for the thermal simulation of buildings is occurring in the last year; they allow the description of the thermal behaviour of buildings during the year, in order to verify their energy efficiencies and to suggest eventual improvements, even at the design stage. These thermal simulation programs generally need a complete input data set and among these, information particularly referring to the climatic conditions of the site where the building will be built-up. As it is well known, a climatic issue, particularly important for the thermal energy balance, is the solar radiation. In this work we have updated a short reference year of the solar radiation, more precisely the Monthly Average Day (MAD) for a town of the Southern Italy (Palermo), which shows climatic features similar to other places in the Mediterranean basin. In addition, we have compared the climatic data of the MAD (for the global and diffuse solar radiations) obtained from hourly measures for seven years, with those obtained both from geo-astronomical parameters and from the monthly average of the daily global solar radiation, which is commonly adopted on purposes. The comparison does suggest a particular caution in the choice of the method used for generating reduced data sets of the solar radiation for these mediterranean.(Author)

Aesthetic experience of dance performances

Vukadinović Maja

2012-01-01

Full Text Available In this study the aesthetic experience of dance performances is investigated. The study includes construction of an instrument for measuring the aesthetic experience of dance performances and an investigation of the structure of both dancers’ and spectators’ aesthetic experience. The experiments are carried out during eight different performances of various dance forms, including classical ballet, contemporary dance, flamenco and folklore. Three factors of aesthetic experience of dance performances are identified: Dynamism, Exceptionality and Affective Evaluation. The results show that dancers’ aesthetic experience has a somewhat different factorial structure from that of the spectators’. Unlike spectators’ aesthetic experience, dancers’ aesthetic experience singles out the Excitement factor. The results are discussed within the context of dancers’ proprioception and spectators’ exteroception since these findings confirm the idea of a significant role of proprioception in dancers’ aesthetic experience.

Development of solar collector to integration in buildings; Udvikling af solfanger til integrering i bygninger

Energy Technology Data Exchange (ETDEWEB)

Holck, O.; Svendsen, S.

2000-07-01

A solar collector has been developed in the project. The development of the collector is based on knowledge from previous projects and the idea of combining existing exterior insulation systems with a solar collector part for renovation purpose. This solar collector especially focuses on the market, which is dedicated to concrete buildings. South heading gable/facade walls in concrete buildings have a potential for utilization of solar energy. With regards to commercial utilization of the results the project has building parts manufacturers and solar collector manufacturers in mind. Besides the housing stock the industry sector is an area where gable solar collectors can be used. To get the right link between the manufactured part and the building, an existing building is referred to in the project. A prefabricated insulation system from Paroc and a liquid heating absorber from Batec have been chosen as the basis of the project. 50 mm wide aluminium profiles from H.S. Hansen have been used, accomplishing a sliding joint to the adjacent building systems. A range of flashing, is available on the market, fits to the 50 mm profile. Based on these choices the concept of utilizing solar energy can be transferred without difficulties to be valid for other exterior insulation systems, absorber types and consumer systems. Technical details concerning profiles and assembling of solar collectors have been analysed in the project and can be seen from the technical drawings. The mounting of the solar collector will be done by crane so that the work can be done fast and efficiently. This is particularly important in narrow streets, as here is no need to establish building sites for a long period. Crane assembling is suitable when the walls have big areas without needs for many cuttings and projections. If there are windows in the gable a vertical assembling of the elements can be the solution as the windows are often placed in a straight line above each other. In the project

Potential application of a centralized solar water-heating system for a high-rise residential building in Hong Kong

2006-01-01

There is a growing, government-led trend of applying renewable energy in Hong Kong. One area of interest lies in the wider use of solar-energy systems. The worldwide fast development of building-integrated solar technology has prompted the design alternative of fixing the solar panels on the external facades of buildings. In Hong Kong, high-rise buildings are found everywhere in the urban districts. How to make full use of the vertical facades of these buildings to capture the most solar radiation can be an important area in the technology promotion. In this numerical study, the potential application of a centralized solar water-heating system in high-rise residence was evaluated. Arrays of solar thermal collectors, that occupied the top two-third of the south and west facades of a hypothetical high-rise residence, were proposed for supporting the domestic hot-water system. Based on typical meteorological data, it was found that the annual efficiency of the vertical solar collectors could reach 38.4% on average, giving a solar fraction of 53.4% and a payback period of 9.2 years. Since the solar collectors were able to reduce the heat transmission through the building envelope, the payback was in fact even shorter if the energy saving in air-conditioner operation was considered

Differences in Itself: Redefining Disability through Dance

Directory of Open Access Journals (Sweden)

Carolien Hermans

2016-11-01

Full Text Available This paper brings together two different terms: dance and disability. This encounter between dance and disability might be seen as an unusual, even conflicting, one since dance is traditionally dominated by aesthetic virtuosity and perfect, idealized bodies which are under optimized bodily control. However, recently there has been a growing desire within dance communities and professional dance companies to challenge binary thinking (beautiful-ugly, perfect-imperfect, valid-invalid, success-failure by incorporating an aesthetic of difference. The traditional focus of dance on appearance (shape, technique, virtuosity is replaced by a focus on how movement is connected to a sense of self. This notion of the subjective body not only applies to the dancer's body but also to disabled bodies. Instead of thinking of a body as a thing, an object (Körper that is defined by its physical appearance, dance is more and more seduced by the body as we sense it, feel it and live it (Leib. This conceptual shift in dance is illustrated by a theoretical analysis of The Cost of Living, a dance film produced by DV8.

Solar Assisted Ground Source Heat Pump Performance in Nearly Zero Energy Building in Baltic Countries

Januševičius, Karolis; Streckienė, Giedrė

2013-12-01

In near zero energy buildings (NZEB) built in Baltic countries, heat production systems meet the challenge of large share domestic hot water demand and high required heating capacity. Due to passive solar design, cooling demand in residential buildings also needs an assessment and solution. Heat pump systems are a widespread solution to reduce energy use. A combination of heat pump and solar thermal collectors helps to meet standard requirements and increases the share of renewable energy use in total energy balance of country. The presented paper describes a simulation study of solar assisted heat pump systems carried out in TRNSYS. The purpose of this simulation was to investigate how the performance of a solar assisted heat pump combination varies in near zero energy building. Results of three systems were compared to autonomous (independent) systems simulated performance. Different solar assisted heat pump design solutions with serial and parallel solar thermal collector connections to the heat pump loop were modelled and a passive cooling possibility was assessed. Simulations were performed for three Baltic countries: Lithuania, Latvia and Estonia.

Dancing Intercorporeality: A Health Humanities Perspective on Dance as a Healing Art.

Science.gov (United States)

Purser, Aimie

2017-12-20

As a contribution to the burgeoning field of health humanities, this paper seeks to explore the power of dance to mitigate human suffering and reacquaint us with what it means to be human through bringing the embodied practice of dance into dialogue with the work of the French philosopher Maurice Merleau-Ponty. Merleau-Ponty's conceptualisation of subjectivity as embodied and of intersubjectivity as intercorporeality frees us from many of the constraints of Cartesian thinking and opens up a new way of thinking about how dance functions as a healing art through its ability to ground and reconnect us with self, world, and others--with our humanity. It is argued that through a Merleau-Pontian framework, we can come to appreciate the true potential of dance as a positive and deeply humanising experience, demonstrating how expressive arts practice understood through the lens of philosophical theory can open up new dimensions of understanding and experience in relation to well-being and self- (and other-) care.

Argiriou, Athanassios A; Bellas-Velidis, Ioannis; Kummert, Michaël; André, Philippe

2004-04-01

An artificial neural network (ANN)-based controller for hydronic heating plants of buildings is presented. The controller has forecasting capabilities: it includes a meteorological module, forecasting the ambient temperature and solar irradiance, an indoor temperature predictor module, a supply temperature predictor module and an optimizing module for the water supply temperature. All ANN modules are based on the Feed Forward Back Propagation (FFBP) model. The operation of the controller has been tested experimentally, on a real-scale office building during real operating conditions. The operation results were compared to those of a conventional controller. The performance was also assessed via numerical simulation. The detailed thermal simulation tool for solar systems and buildings TRNSYS was used. Both experimental and numerical results showed that the expected percentage of energy savings with respect to a conventional controller is of about 15% under North European weather conditions.

Guide for a building energy label. Promoting bio-climatic and solar construction and renovation

Energy Technology Data Exchange (ETDEWEB)

NONE

2004-07-01

Technically speaking, building experts have the knowledge to deal with thermal inertia of buildings, solar gains, insulation, efficient ventilation, and daylighting... to get low energy buildings that provide comfort for the users. Buildings should always be designed according to the specificities of the local climate, according to a ''solar and bio-climatic construction'' approach. It is not always possible to fully apply these principles, particularly in urban areas with high density. However, this is unacceptable to keep building with such errors as insufficient insulation and direct electrical heating, single glazing, thermal bridges, low efficiency heating systems. This guide aims at encouraging the building experts to take into account the energy efficiency. Implementing a building energy label will allow general public to be aware of this issue and then, and will then lead to develop better practices. (author)

To examine the feasibility of a randomized controlled study design and to explore the benefits of a set dancing intervention compared with usual care. Randomized controlled design, with participants randomized to Irish set dance classes or a usual care group. Community based. Individuals with idiopathic Parkinson disease (PD) (N=90). The dance group attended a 1.5-hour dancing class each week for 10 weeks and undertook a home dance program for 20 minutes, 3 times per week. The usual care group continued with their usual care and daily activities. The primary outcome was feasibility, determined by recruitment rates, success of randomization and allocation procedures, attrition, adherence, safety, willingness of participants to be randomized, resource availability, and cost. Secondary outcomes were motor function (motor section of the Unified Parkinson's Disease Rating Scale), quality of life (Parkinson's Disease Questionnaire-39), functional endurance (6-min walk test), and balance (mini-BESTest). Ninety participants were randomized (45 per group). There were no adverse effects or resource constraints. Although adherence to the dancing program was 93.5%, there was >40% attrition in each group. Postintervention, the dance group had greater nonsignificant gains in quality of life than the usual care group. There was a meaningful deterioration in endurance in the usual care group. There were no meaningful changes in other outcomes. The exit questionnaire showed participants enjoyed the classes and would like to continue participation. For people with mild to moderately severe PD, set dancing is feasible and enjoyable and may improve quality of life. Copyright © 2016 American Congress of Rehabilitation Medicine.

Highlights: • A new water purification system with solar and UV-LED powered by PV was proposed. • UV-LED was driven by PV directly without any transformation. • More than 92% of P_m generated by PV was used to drive UV-LED array. • Visible and near-infra light was converted to UV via PV and UV-LED. • The flowing water makes PV and LED work at lower temperature. - Abstract: To increase the photocatalytic reaction rate and make full use of electricity generated by photovoltaics (PV), a water purification system (SOL&PID) with solar and ultraviolet-light emitting diode (UV-LED) powered by a hybrid PV photocatalytic reactor was designed and tested in this paper. The SOL&PID system is based on Solar Water Purification and Renewable Electricity Generation system (SOLWAT). Photovoltaic and photocatalytic performances of SOL&PID system were evaluated in comparison with SOLWAT by the degradation of Acid Red 26 (AR 26) and 4-chlorophenol (4-CP) using suspended TiO_2. To assess the directly-coupled performance between PV and UV-LED array, the power consumption percentage of UV-LED array from the maximum output power of PV was analyzed. The results show an adequate coupling between the UV-LED array and the photovoltaics. More than 92% of the maximum output power generated by PV modules is used to drive the LED array. The photocatalytic reaction rate constants in SOL&PID system increase respectively 29–37% and 31–78% during AR 26 and 4-CP experiments, in comparison with SOLWAT system. Besides, the SOL&PID system achieved lower solar module temperature and lower UV-LED pin temperature than the reference systems by the addition of flow channel.

Building America Case Study: Addressing Multifamily Piping Losses with Solar Hot Water, Davis, California

Energy Technology Data Exchange (ETDEWEB)

2016-12-01

Solar thermal water heating is most cost effective when applied to multifamily buildings and some states offer incentives or other inducements to install them. However, typical solar water heating designs do not allow the solar generated heat to be applied to recirculation losses, only to reduce the amount of gas or electric energy needed for hot water that is delivered to the fixtures. For good reasons, hot water that is recirculated through the building is returned to the water heater, not to the solar storage tank. The project described in this report investigated the effectiveness of using automatic valves to divert water that is normally returned through the recirculation piping to the gas or electric water heater instead to the solar storage tank. The valves can be controlled so that the flow is only diverted when the returning water is cooler than the water in the solar storage tank.

Karkou, Vicky; Meekums, Bonnie

2017-02-03

Dementia is a collective name for different degenerative brain syndromes which, according to Alzheimer's Disease International, affects approximately 35.6 million people worldwide. The latest NICE guideline for dementia highlights the value of diverse treatment options for the different stages and symptoms of dementia including non-pharmacological treatments. Relevant literature also argues for the value of interventions that acknowledge the complexity of the condition and address the person as a whole, including their physical, emotional, social and cognitive processes. At the same time, there is growing literature that highlights the capacity of the arts and embodied practices to address this complexity. Dance movement therapy is an embodied psychological intervention that can address complexity and thus, may be useful for people with dementia, but its effectiveness remains unclear. To assess the effects of dance movement therapy on behavioural, social, cognitive and emotional symptoms of people with dementia in comparison to no treatment, standard care or any other treatment. Also, to compare different forms of dance movement therapy (e.g. Laban-based dance movement therapy, Chacian dance movement therapy or Authentic Movement). Searches took place up to March 2016 through ALOIS, Cochrane Dementia and Cognitive Improvement's Specialized Register, which covers CENTRAL, a number of major healthcare databases and trial registers, and grey literature sources. We checked bibliographies of relevant studies and reviews, and contacted professional associations, educational programmes and experts from around the world. We considered randomised controlled trials (RCTs) in any language, including cross-over design and cluster-RCTs for inclusion. Studies considered had to include people with dementia, in any age group and in any setting, with interventions delivered by a dance movement therapy practitioner who (i) had received formal training (ii) was a dance movement

Navigating a Precarious Balance: The Noel Garovillo Dance Center's Contemporary Dance as a Commitment to the Community

Full Text Available If it is difficult to picture a ballet school located in Koronadal, South Cotabato, then perhaps it will even take more than a stretch of the imagination to conceive of how contemporary dance survives in Southern Philippines. The story behind the KAHAYAG Community Dance and Theater Company, later reorganized and renamed as the Noel Garrovillo Dance Center, is a narrative of how, notwithstanding the obstacles faced by dance in the regions, sheer conviction and commitment could keep the art form alive. It is also a story of how a dance director and his company had to resolve their contradictions as Christian artist settlers in Mindanao. This paper discusses how contemporary dance as a flexible and dynamic dance form has allowed them to create pieces that they could consider their “own.” From their initial works that borrowed movements from the T’bolis and B’laans, to their current choreographies based on their realities as settlers in Koronadal, Garrovillo’s company has continuously worked to make dance part of the local government’s agenda on cultural and the arts. As cultural brokers, they are faced with both choreographic and intellectual imperatives. Garrovillo believes that there is a need to strengthen the country’s creative industry so that choreographers will have opportunities to create works which are crucial to the life of the nation.

Performative building envelope design correlated to solar radiation and cooling energy consumption

Climate change as an ongoing anthropogenic environmental challenge is predominantly caused by an amplification in the amount of greenhouse gases (GHGs), notably carbon dioxide (CO2) in building sector. Global CO2 emissions are emitted from HVAC (Heating, Ventilation, and Air Conditioning) occupation to provide thermal comfort in building. In fact, the amount of energy used for cooling or heating building is implication of building envelope design. Building envelope acts as interface layer of heat transfer between outdoor environment and the interior of a building. It appears as wall, window, roof and external shading device. This paper examines performance of various design strategy on building envelope to limit solar radiation and reduce cooling loads in tropical climate. The design strategies are considering orientation, window to wall ratio, material properties, and external shading device. This research applied simulation method using Autodesk Ecotect to investigate simultaneously between variations of wall and window ratio, shading device composition and the implication to the amount of solar radiation, cooling energy consumption. Comparative analysis on the data will determine logical variation between opening and shading device composition and cooling energy consumption. Optimizing the building envelope design is crucial strategy for reducing CO2 emissions and long-term energy reduction in building sector. Simulation technology as feedback loop will lead to better performative building envelope.

To explore the views of people with Parkinson's and their dance partners on the influence and issues surrounding dancing with an able-bodied dance partner during partnered ball room dance classes. In depth, semi-structured interviews explored purposively selected participants' experiences and views about dance classes. Fourteen people with Parkinson's and their dance partners (six spouses, two friends/relatives, five volunteers) were interviewed within a month of completing the 10-week dance class program. Data were analyzed thematically. Generally, those partnered with a spouse or an experienced dancer, or when dance couples were able to develop good rapport, gained greater enjoyment and sense of achievement from dance classes in comparison to couples who did not enjoy dancing together or had clashing approaches to dance. Managing and negotiating who would "lead" in a dance was challenging for dance couples particularly among male people with Parkinson's. People with Parkinson's experience of the dance classes were influenced by the relationship and compatibility with their dance partner. Dance partnerships may impact on recruitment, enjoyment, outcome and continued participation in dance classes. Potential effects of partnerships should be analyzed and reported in studies evaluating the outcomes of dance classes. Implications for rehabilitation We recommend that health professionals consider involving spouses in Parkinson's dance classes as this may improve recruitment, adherence, enjoyment and overall outcome of the dance classes. If volunteers are needed, aim to recruit those who already have good dancing ability, convey a love of dancing and have the sensitivity and social skills to interact positively with the person with Parkinson's. Consider dance partnership issues when advertising and promoting dance classes. Address partnership issues through open communication and by changing partners if the dance partnership is not working well.

2005-01-01

Air-fall dust accumulates on the solar panels of NASA's Mars Exploration Rovers, reducing the amount of sunlight reaching the solar arrays. Pre-launch models predicted steady dust accumulation. However, the rovers have been blessed with occasional wind events that clear significant amounts of dust from the solar panels. This graph shows the effects of those panel-cleaning events on the amount of electricity generated by Spirit's solar panels. The horizontal scale is the number of Martian days (sols) after Spirit's Jan. 4, 2005, (Universal Time) landing on Mars. The vertical scale indicates output from the rover's solar panels as a fraction of the amount produced when the clean panels first opened. Note that the gradual declines are interrupted by occasional sharp increases, such as a dust-cleaning event on sol 420.

Projects which relate to the current national thrust toward demonstrating applied solar energy are discussed. The first project has as its primary objective the application of a system comprised of a flat plate collector field, an absorption air conditioning system, and a hot water heating system to satisfy most of the annual cooling and heating requirements of a large commercial office building. The other project addresses the application of solar collector technology to the heating and hot water requirements of a domestic residence. In this case, however, the solar system represents only one of several important technology items, the primary objective for the project being the application of space technology to the American home.

Dance/movement therapy may be defined as a psychosocial and body-oriented art therapy, which uses dance for the expression of emotional and cognitive issues. Dance/movement therapy is an important intervention for cancer patients to enhance coping strategies. There are only few studies investigating dance therapy with cancer patients. The present study investigates effects of dance/movement therapy (n = 115) in the setting of inpatient rehabilitation based on a pre-post design with a control group as well as a follow-up 3 months later. Standardized questionnaires measuring quality of life, anxiety and depression, and self-concept (EORTC QLQ-C30, HADS, FSKN) were used. In addition, at the end of the inpatient rehabilitation program subjective expectations of the dance/movement therapy and the patients' subjective evaluation of the benefits of the intervention were measured by a new developed questionnaire. As process factors of dance/movement therapy, expression of emotions, enhancement of self-esteem, development of the personality, vitality, getting inner balance, and getting in touch with the body have been identified. In terms of quality of life and psychological well-being, the results showed significant improvements with medium to large effect sizes. Even though those effects may not be attributed to the intervention alone, the analysis of the data and the patients' subjective statements help to reveal therapeutic factors and process characteristics of dance/movement therapy within inpatient rehabilitation.

Highlights: • A model for optimal component sizes of hybrid energy system (HES) is presented. • The techno-economic feasibility of PV for building in context of China is studied. • The use of PV reduces COE by 46% for customers in the commercial building. • The use of PV increases COE by 9.55% for customers in the residential building. - Abstract: The Building Added PV (BAPV) plays an important role for developing green buildings. This work conducts a techno-economic feasibility study of BAPV for commercial and residential building hybrid energy systems (HES). A component sizing model based on the optimal power dispatch simulations with the objective of minimum cost of energy (COE) is used to determine the component sizes of HES. The techno-economic performances of two HES composed of BAPV and batteries for residential and commercial buildings are investigated. The results show that the use of BAPV in the commercial building HES can reduce the electricity bill for customers owing to the government subsidies on PV as well as due to the similar characteristics of the load profile as to the solar radiation profile. However, due to temporal dislocation between the load and solar radiation patterns, the use of PV in the residential building HES may significantly increase the initial capital cost and replacement cost of battery, resulting in the COE of the residential building HES with BAPV even higher than the residential electricity price. The techno-economic performances of battery (e.g., the lifetime and capital cost) have more effect on the COE of the residential building HES than that of PV.

Full Text Available The function of the honey bee tremble dance and how it attracts signal receivers is poorly understood. We tested the hypothesis that tremble followers and waggle followers exhibit the same dance-following behavior. If correct, this could unify our understanding of dance following, provide insight into dance information transfer, and offer a way to identify the signal receivers of tremble dance information. Followers showed similar initial attraction to and tracking of dancers. However, waggle dancers were faster than tremble dancers, and follower-forward, -sideways, and -angular velocities were generally similar to the velocities of their respective dancers. Waggle dancers attracted followers from 1.3-fold greater distances away than tremble dancers. Both follower types were attracted to the lateral sides of dancers, but tremble followers were more attracted to the dancer's head, and waggle followers were more attracted to the dancer's abdomen. Tremble dancers engaged in 4-fold more brief food exchanges with their followers than waggle dancers. The behaviors of both follower types are therefore relatively conserved. Researchers can now take the next steps, observing tremble followers to determine their subsequent behaviors and testing the broader question of whether follower attraction and tracking is conserved in a wide range of social insects.

Dancing for Healthy Aging: Functional and Metabolic Perspectives.

Science.gov (United States)

Rodrigues-Krause, Josianne; Krause, Mauricio; Reischak-Oliveira, Alvaro

2018-02-10

Context • Dancing has been used as a form of exercise to improve functional and metabolic outcomes during aging. The field lacks randomized, clinical trials (RCTs) evaluating metabolic outcomes related to dance interventions, but dancing may be a form of exercise that could induce positive effects on the metabolic health of older adults. However, primary studies seem very heterogonous regarding the trial designs, characteristics of the interventions, the methods for outcomes assessments, statistical powers, and methodological quality. Objective • The current research team intended to review the literature on the use of dance as a form of intervention to promote functional and metabolic health in older adults. Specifically, the research team aimed to identify and describe the characteristics of a large range of studies using dance as an intervention, summarizing them and putting them into perspective for further analysis. Design • The research team searched the following data sources-MEDLINE, Cochrane Wiley, Clinical Trials.gov, the Physiotherapy Evidence Database (PEDRO), and the Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS)-for RCTs, quasi-experimental studies, and observational trials that compared the benefits of any style of dancing, combined with other exercises or alone, to nonexercising controls and/or controls practicing other types of exercise. Setting • The study took place at the Federal University of Rio Grande do Sul (Porto Alegre, Brazil). Participants were aging individuals, >55 y, both with or without health conditions. Interventions • Interventions should be supervised, taking form as group classes, in a dance setting environment. Dance styles were divided into 5 categories for the review: (1) cultural dances developed by groups of people to reflect the roots of a certain region, such as Greek dance; (2) ballroom dance (ie, dances with partners performed socially or competitively in a ballroom, such as foxtrot

Rietveld, Boni; van de Wiel, Albert

2011-01-01

Professional theatre dance has high and specific physical demands, comparable to top sport. Dance injuries are often caused by faulty technique due to compensation for physical limitations. Knowledge of these limitations and professional teaching can prevent many problems. Dance injuries mostly involve the lower limbs, especially the ankles and knees. Dance injuries require that the medical professional has knowledge of dance technique and respects the passion of the dancer. The advice to stop dancing has hardly ever to be given. Scientific, prospective dance medical research is recommended.

Review of the Department of Trade and Industry passive solar programme. Pt. 2: non-domestic buildings. Final report

International Nuclear Information System (INIS)

1997-06-01

The aim of the Passive Solar Programme (PSP) was to quantify the nature, size and timing of passive solar contribution to the UK building stock and the energy savings; to determine the best and most cost effective methods of achieving savings; to explore and develop better techniques; and to transfer the information to the appropriate people. There are over 1.25 million non-domestic buildings in the UK. It has been calculated that it is technically and economically possible to use passive solar design along with improved efficiency measures to reduce energy consumption in the UK by 25% in most existing non-domestic buildings and over 50% in new buildings. From the UK Government's point of view the savings are potentially very significant, and initiatives are aimed at bringing passive solar design into wide use at the earliest possible date. The PSP was intended to encourage the use of passive solar design and displace other forms of energy consumption. The earlier passive solar programme was focused on the domestic sector, where the primary concern was to reduce energy consumed in space heating. Its extension to non-domestic buildings demanded a broader definition of the potential benefits. (author)

'Shall We Dance'? Older Adults' Perspectives on the Feasibility of a Dance Intervention for Cognitive Function.

Science.gov (United States)

Thøgersen-Ntoumani, Cecilie; Papathomas, Anthony; Foster, Jonathan; Quested, Eleanor; Ntoumanis, Nikos

2017-12-28

We explored perceptions of social dance as a possible intervention to improve cognitive functioning in older adults with subjective memory complaints. Thirty participants (19 female; M age = 72.6; SD=8.2) took part in the study. This included 21 participants who had self-reported subjective memory complaints and 9 spouses who noticed spousal memory loss. Semi-structured interviews were conducted and thematic analysis was used to analyze the data. Three main themes were constructed: 1) dance seen as a means of promoting social interaction; 2) chronic illness as a barrier and facilitator to participation; 3) social dance representing nostalgic connections to the past. Overall, the participants were positive about the potential attractiveness of social dance to improve cognitive and social functioning and other aspects of health. It is important in future research to examine the feasibility of a social dance intervention among older adults with subjective memory complaints.

Conditioning Methodologies for DanceSport: Lessons from Gymnastics, Figure Skating, and Concert Dance Research.

Science.gov (United States)

Outevsky, David; Martin, Blake Cw

2015-12-01

Dancesport, the competitive branch of ballroom dancing, places high physiological and psychological demands on its practitioners, but pedagogical resources in these areas for this dance form are limited. Dancesport competitors could benefit from strategies used in other aesthetic sports. In this review, we identify conditioning methodologies from gymnastics, figure skating, and contemporary, modern, and ballet dance forms that could have relevance and suitability for dancesport training, and propose several strategies for inclusion in the current dancesport curriculum. We reviewed articles derived from Google Scholar, PubMed, ScienceDirect, Taylor & Francis Online, and Web of Science search engines and databases, with publication dates from 1979 to 2013. The keywords included MeSH terms: dancing, gymnastics, physiology, energy metabolism, physical endurance, and range of motion. Out of 47 papers examined, 41 papers met the inclusion criteria (validity of scientific methods, topic relevance, transferability to dancesport, publication date). Quality and validity of the data were assessed by examining the methodologies in each study and comparing studies on similar populations as well as across time using the PRISMA 2009 checklist and flowchart. The relevant research suggests that macro-cycle periodization planning, aerobic and anaerobic conditioning, range of motion and muscular endurance training, and performance psychology methods have potential for adaptation for dancesport training. Dancesport coaches may help their students fulfill their ambitions as competitive athletes and dance artists by adapting the relevant performance enhancement strategies from gymnastics, figure skating, and concert dance forms presented in this paper.

Energy balance in a passive solar building. An attempt at economic assessment

Directory of Open Access Journals (Sweden)

Sobczyk Wiktoria

2016-01-01

Full Text Available The paper emphasizes possibilities for substantially reducing energy consumption with modern ecofriendly buildings. Passive building construction is a sector of the construction industry that has extremely low demand for the energy for heating house interiors. A passive house requires a small amount of energy to provide thermal comfort, but it requires proper systems (HRU, heat pumps, solar collectors to accomplish that effect. The modification proposal presented in the paper has dramatically reduced the demand for heat capacity of the building. Unfortunately the passive standard has not been reached, but thermomodernisation would allow for a significant reduction of heating costs. The demand per 1 m2 of heated surface area in a traditional building was 41.9 W/m2, while after the modification – only 15.01 W/m2. The tested building, if located in a warmer climate, with an average outside temperature of ≥ -10ºC would certainly perform its function. The use of modern technology ensures high energy savings. Such solutions, however, are not the cheapest on the market, and therefore are less available. The construction of a passive solar buildings is a “green” investment with tangible environmental results. By ensuring the thermomodernisation of a traditional building we can enjoy real environmental and economic benefits.

Coloured solar collectors. Phase II : from laboratory samples to collector prototypes. Final report

Energy Technology Data Exchange (ETDEWEB)

Schueler, A; Roecker, Ch; Chambrier, E de; Munari Probst, M

2007-07-01

This illustrated final report for the Swiss Federal Office of Energy (SFOE) deals with the second phase of a project concerning the architectural integration of glazed solar collectors into the facades of buildings for heat production. The factors that limit the integration of photovoltaic panels in facades are discussed. The authors state that, for a convincing demonstration, sufficiently large samples and high quality levels are needed. The sol-gel deposition of the multi-layered coatings on A4-sized glass panes demonstrated in the laboratory by EPFL-LESO are discussed. The coatings produced exhibit a coloured reflection in combination with a high solar transmittance, a homogenous appearance, and are free of visible defects. Film hardening by UV exposure is discussed: This should result in the speeding up of the sol-gel process and thus save energy, thereby significantly reducing costs. Collaboration with industry is discussed in which full-scale glass panes are to be coated with novel multiple layers. The novel glazing is to be integrated into first prototype collectors. The manufacturing and test processes for the prototypes manufactured are discussed in detail.

The dancing plague: a public health conundrum.

Science.gov (United States)

Donaldson, L J; Cavanagh, J; Rankin, J

1997-07-01

The phenomenon of mass, frenzied dancing affected large populations in various parts of Europe from the thirteenth century and lasted, on and off, for three centuries. The exact aetiology of the Dancing Plague (or Dancing Mania) is still unclear. Retrospective historical review of this public health problem reveals claims for causative factors including demonic possession, epilepsy, the bite of a tarantula, ergot poisoning and social adversity. It seems unlikely that Dancing Mania resulted from a single cause but rather resulted from multiple factors combining with a predisposing cultural background and triggered by adverse social circumstances. Dancing Mania remains one of the unresolved mysteries of public health.

Full Text Available Aligned ZnO Nanorod arrays are deposited on the Sn-doped ZnO thin film via sonicated sol-gel immersion method. The structural, optical, and electrical properties of the Sn-doped ZnO thin films were investigated. Results show that the Sn-doped ZnO thin films with small grain size (~20 nm, high average transmittance (96% in visible region, and good resistivity 7.7 × 102 Ω·cm are obtained for 2 at.% Sn doping concentration. The aligned ZnO nanorod arrays with large surface area were also obtained for 2 at.% Sn-doped ZnO thin film. They were grown on sol-gel derived Sn-doped ZnO thin film, which acts as a seed layer, via sonicated sol-gel immersion method. The grown aligned ZnO nanorod arrays show high transmittance at visible region. The fabricated dye-sensitised solar cell based on the 2.0 at.% Sn-doped ZnO thin film with aligned ZnO nanorod arrays exhibits improved current density, open-circuit voltage, fill factor, and conversion efficiency compared with the undoped ZnO and 1 at.% Sn-doped ZnO thin films.

Augmenting a Ballet Dance Show Using the Dancer's Emotion: Conducting Joint Research in Dance and Computer Science

Science.gov (United States)

Clay, Alexis; Delord, Elric; Couture, Nadine; Domenger, Gaël

We describe the joint research that we conduct in gesture-based emotion recognition and virtual augmentation of a stage, bridging together the fields of computer science and dance. After establishing a common ground for dialogue, we could conduct a research process that equally benefits both fields. As computer scientists, dance is a perfect application case. Dancer's artistic creativity orient our research choices. As dancers, computer science provides new tools for creativity, and more importantly a new point of view that forces us to reconsider dance from its fundamentals. In this paper we hence describe our scientific work and its implications on dance. We provide an overview of our system to augment a ballet stage, taking a dancer's emotion into account. To illustrate our work in both fields, we describe three events that mixed dance, emotion recognition and augmented reality.

Intra-dance variation among waggle runs and the design of efficient protocols for honey bee dance decoding

Directory of Open Access Journals (Sweden)

Margaret J. Couvillon

2012-03-01

Noise is universal in information transfer. In animal communication, this presents a challenge not only for intended signal receivers, but also to biologists studying the system. In honey bees, a forager communicates to nestmates the location of an important resource via the waggle dance. This vibrational signal is composed of repeating units (waggle runs that are then averaged by nestmates to derive a single vector. Manual dance decoding is a powerful tool for studying bee foraging ecology, although the process is time-consuming: a forager may repeat the waggle run 1- >100 times within a dance. It is impractical to decode all of these to obtain the vector; however, intra-dance waggle runs vary, so it is important to decode enough to obtain a good average. Here we examine the variation among waggle runs made by foraging bees to devise a method of dance decoding. The first and last waggle runs within a dance are significantly more variable than the middle run. There was no trend in variation for the middle waggle runs. We recommend that any four consecutive waggle runs, not including the first and last runs, may be decoded, and we show that this methodology is suitable by demonstrating the goodness-of-fit between the decoded vectors from our subsamples with the vectors from the entire dances.

Dance movement therapy and falls prevention.

Science.gov (United States)

Veronese, Nicola; Maggi, Stefania; Schofield, Patricia; Stubbs, Brendon

2017-08-01

Falls are a leading cause of morbidity, healthcare use and mortality. Dance is a popular form of physical activity among older people and previous research has suggested that it may improve various health outcomes in this population, including balance, gait and muscle performance. A systematic review of the potential benefits of dance on falls and fear of falling is lacking. Thus, we conducted a systematic review considering all randomized controls trials (RCTs) investigating if dance can reduce falls and improve fear of falling in older adults. Major databases were searched from inception until 1 March 2017 and a total of 10 RCTs were identified, which included a total of 680 people (n=356 dance, n=324 control). Overall, the mean age of the samples was 69.4 years, and 75.2% were female. Across four RCTs, dance therapy reduced falls versus usual care in only one study. Dance therapy improved fear of falling in two out of three included RCTs. There were no serious adverse events reported in the RCTs. In summary, we found a paucity of studies investigating the effect of dance on falls and fear of falling and the evidence base is preliminary and equivocal. Given the heterogeneity of the included samples and interventions, in addition to the short-term follow-up, no firm conclusions can be drawn. However, dance appears to be safe and, given its popularity and demonstrated benefits on other health/wellbeing outcomes in older adults, it is important that future research considers its potential benefits on falls/fear of falling in older age.

Nanocrystalline semiconductor metal oxides have achieved a great importance in our industrial world today. They may be defined as metal oxides with crystal size between 1 and 100 nm. TiO2 nanosize particles have attracted significant interest of materials scientists and physicists due to their special properties and have attained a great importance in several technological applications such as photocatalysis, sensors, solar cells and memory devices. TiO2 nanoparticles can be produced by a variety of techniques ranging from simple chemical to mechanical to vacuum methods, including many variants of physical and chemical vapour deposition techniques. In the present research work we report the synthesis of TiO2 nanoparticles by Sol-Gel technique. The characterization of particles was carried out by XRD and XRF techniques. The importance and applications of these nanoparticles for solar cells are also discussed in this work.

Occupational therapy's dance with diversity.

Science.gov (United States)

Black, Roxie M

2002-01-01

As the demographics of the United States continue to change and we become a more pluralistic society, the increased diversity of the occupational therapy workforce and our consumers calls for an examination of the profession's stance on multiculturalism and diversity. Using the metaphor of dance, this article identifies the dance partners as the organization's leaders and its members. A historical review of the profession from the 1940s to the present traces the partners' steps to determine which led the dance of diversity during the profession's development. In this review, I discovered that the period when the profession most effectively and productively explored issues of diversity was during the early- to mid-1990s--a time when the organization and its members worked in harmony. At that time, occupational therapy's dance with diversity flowed with rhythm and synchronicity.

Alternative for Summer Use of Solar Air Heaters in Existing Buildings

Directory of Open Access Journals (Sweden)

Sergio L. González-González

2017-07-01

Full Text Available Among solar thermal technologies for indoor heating, solar air heaters (SAH are appealing for implementation on existing buildings due to their simplicity, fewer risks related to the working fluid, and possible independence from the building structure. However, existing research work mainly focuses on winter use and still fails in providing effective solutions for yearly operation, which would enhance their interest. With the aim of analysing an alternative summer use, this work firstly characterises a double channel-single pass solar air collector through experimentation. From the obtained results, modelling and simulation tasks have been conducted to evaluate the possibilities of using hot air, provided by the SAH, while operating under summer conditions within a closed loop, to feed an air-to-water heat exchanger for domestic hot water (DHW production. The system is studied through simulation under two different configurations for a case study in Valladolid (Spain, during the period from May to September for different airflows in the closed loop. Results show that daily savings can vary from 27% to 85% among the different operating conditions; a configuration where make-up water is fed to the heat exchanger being preferable, with a dedicated water tank for the solar heated water storage of the minimum possible volume. The more favourable results for the harshest months highlight the interest of extending the use of the solar air heaters to the summer period.

On the Evaluation of Solar Greenhouse Efficiency in Building Simulation during the Heating Period

Directory of Open Access Journals (Sweden)

Francesco Asdrubali

2012-06-01

Full Text Available Among solar passive systems integrated in buildings, sunspaces or solar greenhouses represent a very interesting solution. A sunspace is a closed, southbound volume, constituted by transparent surfaces, adjacent to a building, which reduces winter energy demand thanks to the use of solar gains. The effect of a typical solar greenhouse on the energy balance of a building was evaluated during the heating period with two stationary procedures (Method 5000 and EN ISO 13790 and with a dynamic tool (TRNSYS. After the analysis of the greenhouse alone, the behavior of an entire house was simulated; a flat equipped with a sunspace, recently built thanks to public contributions provided by the Umbria Region in Italy to widespread bio-climatic architecture, was used as case-study. Simulations were carried out for the examined flat, both with a steady-state tool and with a dynamic one; the contribution of the sunspace was estimated thanks to the various methods previously mentioned. Finally, the simulated data were satisfactorily compared with the real energy consumptions (natural gas for heating of the flat; the sunspace allows a reduction of winter energy demand of the flat of about 20%.

Building-Integrated Solar Energy Devices based on Wavelength Selective Films

Science.gov (United States)

Ulavi, Tejas

A potentially attractive option for building integrated solar is to employ hybrid solar collectors which serve dual purposes, combining solar thermal technology with either thin film photovoltaics or daylighting. In this study, two hybrid concepts, a hybrid photovoltaic/thermal (PV/T) collector and a hybrid 'solar window', are presented and analyzed to evaluate technical performance. In both concepts, a wavelength selective film is coupled with a compound parabolic concentrator (CPC) to reflect and concentrate the infrared portion of the solar spectrum onto a tubular absorber. The visible portion of the spectrum is transmitted through the concentrator to either a thin film Cadmium Telluride (CdTe) solar panel for electricity generation or into the interior space for daylighting. Special attention is given to the design of the hybrid devices for aesthetic building integration. An adaptive concentrator design based on asymmetrical truncation of CPCs is presented for the hybrid solar window concept. The energetic and spectral split between the solar thermal module and the PV or daylighting module are functions of the optical properties of the wavelength selective film and the concentrator geometry, and are determined using a Monte Carlo Ray-Tracing (MCRT) model. Results obtained from the MCRT can be used in conjugation with meteorological data for specific applications to study the impact of CPC design parameters including the half-acceptance angle thetac, absorber diameter D and truncation on the annual thermal and PV/daylighting efficiencies. The hybrid PV/T system is analyzed for a rooftop application in Phoenix, AZ. Compared to a system of the same area with independent solar thermal and PV modules, the hybrid PV/T provides 20% more energy, annually. However, the increase in total delivered energy is due solely to the addition of the thermal module and is achieved at an expense of a decrease in the annual electrical efficiency from 8.8% to 5.8% due to shading by

An analysis is performed to show that a utility solar-passive strategy can be used rather effectively in aiding the utility to obtain more efficient load factors and lower costs. The objectives are to determine the impact of active and passive solar energy designs for space conditioning and hot water heating for the residential sector upon the diurnal and annual load curves for several utilities, to assess the effect of present utility pricing policies, and to examine alternative pricing schemes, as well as Federal and state tax credits, as they may affect the optimal sizing and configuration of active solar and passive solar building components. The methodology, the systems model, an overall building design, building cost determination, and a description of TRNSYS are presented. The major parameters discussed that distinguish variation in the cost-effectiveness of particular building design fall into 5 categories: the weather, building configurations, building costs, utility costs and rates, and financial parameters (inclusive of tax credits for solar and energy conservation investment). Five utilities are studied: Colorado Springs Department of Public Utilities; Public Service Co. of New Mexico; New England Electric System; Pacific Gas and Electric; and Georgia Power Co.

The commercial sector offers strong potential for solar photovoltaics (PV) owing to abundant available roof space suitable for PV and the opportunity to offset the sector's substantial retail electricity purchases. This report evaluated the breakeven price of PV for 15 different building types and various financing options by calculating electricity savings based on detailed rate structures for most U.S. utility territories (representing approximately two thirds of U.S. commercial customers). We find that at current capital costs, an estimated 1/3 of U.S. commercial customers break even in the cash scenario and approximately 2/3 break even in the loan scenario. Variation in retail rates is a stronger driver of breakeven prices than is variation in building load or solar generation profiles. At the building level, variation in the average breakeven price is largely driven by the ability for a PV system to reduce demand charges.

Physics and the Art of Dance - Understanding Movement

Science.gov (United States)

Swope, Kenneth Laws

2005-03-01

Written by a physicist with professional dance training, Physics and the Art of Dance explains how dancers can achieve better, safer performances through an understanding of physics in motion. Using simple, non-technical terms, Kenneth Laws combines his knowledge of both physics and dance to describe how the laws of gravity, momentum, and energy affect dancing bodies. The book explores the natural laws that govern the subtleties of balance, the techniques of leaps and pirouettes, and the impressive lifts and turns executed by ballet partners. Finally, Laws offers insight into two current discussions in the dance world--the effect of body size on ballet technique, and the relationship between science and the art of dance. Beautiful, original stop-action photographs by Martha Swope, along with clear diagrams, illustrate the concepts described in the text. Plus, an intriguing "puzzler" at the beginning of each chapter provides an engaging entree into the topics presented. For those who want a more advanced understanding of the physics, extensive appendices are provided. This new book combines the best features of Laws's widely acclaimed The Physics of Dance and Physics, Dance, and the Pas de Deux by Laws and Cynthia Harvey. Its expert application of the basic principles of physics to the art of dance will be an invaluable resource for dancers and dance instructors and will open a new level of appreciation for lovers of the form. It will also appeal to physicists who seek to include the arts in their scientific pursuits.

SSRI Facilitated Crack Dancing

Directory of Open Access Journals (Sweden)

Ravi Doobay

2017-01-01

Full Text Available Choreoathetoid movement secondary to cocaine use is a well-documented phenomenon better known as “crack dancing.” It consists of uncontrolled writhing movements secondary to excess dopamine from cocaine use. We present a 32-year-old male who had been using cocaine for many years and was recently started on paroxetine, a selective serotonin reuptake inhibitor (SSRI for worsening depression four weeks before presentation. He had been doing cocaine every 2 weeks for the last three years and had never “crack danced” before this episode. The authors have conducted a thorough literature review and cited studies that suggest “crack dancing” is associated with excess dopamine. There has never been a documented case report of an SSRI being linked with “crack dancing.” The authors propose that the excess dopaminergic effect of the SSRI lowered the dopamine threshold for “crack dancing.” There is a communication with the Raphe Nucleus and the Substantia Nigra, which explains how the SSRI increases dopamine levels. This is the first documented case of an SSRI facilitating the “crack dance.”

DANCE MUSIC: GENDER ISSUES AND EMBODIMENT OF NATIONAL IDENTITY

Full Text Available Drawing on research of contemporary dance music this study analyzes how practices of, and discourse about, contemporary dance music contribute to the performance and embodiment of gender, and national identities. This article examines the articulation of gender and national identity in performance in the specific context of Russian contemporary male national dance. Dance in particular is a very interesting research setting for a subject as identity. Dance is located mostly outside of the daily life setting, therefore it enables another social framework with different social norms and rules than the ones applicable in daily life. Especially the identity axes of gender and national identity are provoked by national dances. To create insight and to understand the background and discourse of her research, the author presents the theoretical framework at first. Next her argument will be elucidated by the empirical chapters, which represent her findings in the field. At the end the author answers her research questions, as well as evaluating some existing theories on the topic, in her conclusion. The conclusion is that the bodies of dancers are cultural bodies and dance movements can be seen as scripts, which are culturally encoded and part of daily life. The body is the materialization of cultural definitions of femininity and masculinity, maleness and femaleness, and also materializes the dancer’s interpretation of them, as was stated by Aalten (1997. Namely, dancers create and recreate their gender and national identity inter-subjectively while dancing. Dance allow people to reclaim their humanity and is inscribed within the realm of feeling and emotion, The dancing body is a symbolic expression that may embody many notions of desire, hate, romance, anger, sexual climax. Dance, dance music and culture are intrinsically connected. Dancers and their dance practices reflect what exist in a society and culture, like how sexuality and gender are

Full Text Available The Wa nationality, a typical ethnic group in Yunnan province, is an ancient one lives across Yunnan. The main residences of it are border area beside northern Yunnan and the Wa States in Burma. Among all the Wa dances, Wooden Drum Dancing leads a vital position, and it is also a symbolic dancing in the culture of Wa people. The feature of Wooden Drum Dancing is that every action expending by the beats of wooden drum, namely, first the wooden drum, then the Wooden Drum Dancing. Dancing is an important content in the life of Wa people, and the aesthetics of life comes from dancing, so they present their value on worship by the form of dancing. This article is going to interpret the aesthetic standard on Wa people’s Wooden Drum Dancing by the view of aesthetics, and come into a conclude that the inspiration of such dancing came from practice and their worship to nature and ancestor. The Wooden Drum Dancing displays totally the tough air and solidarity of Wa people, which also presents the fair society of them. The Wooden Drum Dancing is an enriched art that Wa People took from particle life, so dancing of Wa is often classified into the aesthetic area of plain. The information of people’s living situation displayed by Wa dancing also conveys their rich emotions. The sense of beauty within Wooden Drum Dancing will give others a solemn feeling. The formal beauty is displayed by the rhythm of upper part of body, and the power beauty is displayed by the rhythm of the lower part of body.

Full Text Available This is a qualitative investigation to analyse native dance in North-eastern Thailand. There were three objectives for this investigation, which were to study the history of Isan folk dance, current dance postures and ways to conserve the current dance postures of Isan folk artists. Research tools were interview, observation, participation, focus group discussion and workshop. The purposively selected research sample was composed of 3 groups of national artists. The findings show that Isan folk dancer shave their own unique dancing styles. Each artist has his or her own identity, which is constructed based on personal experience of dancing and singing. Mor lam is a dance used to accompany traditional Isansung poetry. Modern dance postures have been adapted from the traditional forms. Dance postures have been adapted from three primary sources: traditional literature, the ethnic and Lanchang dancing in the Lao People’s Democratic Republic and rhythmic Khon Kaen compositions. The conclusions of this investigation suggest that preservation of the dancing arts and postures should centre on the incorporation of new knowledge, as well as the continuation of traditional dance postures. Further research is required for people interested in performing arts conservation in other provinces and other traditional performing arts.

Integration of phase-change materials (PCMs) into building fabrics is considered to be one of the potential and effective ways of minimising energy-consumption and CO{sub 2}-emissions in the building sector. In order to assess the thermal effectiveness of this concept, composite PCM drywall samples (i.e., randomly mixed and laminated PCM drywalls) have been evaluated in a model passive-solar building. For a broader assessment, the effects of three phase-change zones (narrow, intermediate and wide) of the PCM sample were considered. The results showed that the laminated PCM sample with a narrow phase-change zone was capable of increasing the minimum room temperature by about 17% more than the randomly mixed type. Even though there was some display of a non-isothermal phase-change process, the laminated system proved to be thermally more effective in terms of evolution and utilisation of latent heat. A further heat-transfer enhancement process is, however, required for the development of the laminated system. . (author)

In his recent works on daily face-to-face encounters, Zahavi claims that the phenomenon of sharing involves reciprocity. Following Zahavi’s line of thought, we wonder what exactly reciprocity amounts to and how the shared experience emerges from the dynamic process of interaction. By turning...... to the highly specialized field of elite sports dance, we aim at exploring the way in which reciprocity unfolds in intensive deliberate practices of movement. In our analysis, we specifically argue that the ongoing dynamics of two separate flows of movement constitute a shared experience of dancing together...

Dynamic window daylighting systems: electropolymeric technology for solar responsive building envelopes

Science.gov (United States)

Krietemeyer, Elizabeth A.; Smith, Shane I.; Dyson, Anna H.

2011-04-01

Human health and energy problems associated with the lack of control of sunlight in contemporary buildings have necessitated research into dynamic windows for energy efficient buildings. Existing window technologies have made moderate progress towards greater energy performance for facades but remain limited in their response to dynamic solar conditions, building energy requirements, and variable user preferences for visual comfort. Recent developments in electropolymeric display technology provide opportunities to transfer electroactive polymers to windows that can achieve high levels of geometric and spectral selectivity through the building envelope in order to meet the lighting, thermal and user requirements of occupied spaces. Experimental simulations that investigate daylight quality, energy performance, and architectural effects of electropolymeric glazing technology are presented.

Full Text Available The building sector accounts for more than 40% of the global energy consumption. This consumption may be lowered by reducing building energy requirements and using renewable energy in building energy supply systems. Therefore, a nearly zero-energy building, incorporating a solar heating and cooling system, was designed and built in Beijing, China. The system included a 35.17 kW cooling (10-RT absorption chiller, an evacuated tube solar collector with an aperture area of 320.6 m2, two hot-water storage tanks (with capacities of 10 m3 and 30 m3, respectively, two cold-water storage tanks (both with a capacity of 10 m3, and a 281 kW cooling tower. Heat pump systems were used as a backup. At a value of 25.2%, the obtained solar fraction associated with the cooling load was close to the design target of 30%. In addition, the daily solar collector efficiency and the chiller coefficient of performance (COP varied from 0.327 to 0.507 and 0.49 to 0.70, respectively.

Example-Based Automatic Music-Driven Conventional Dance Motion Synthesis

Energy Technology Data Exchange (ETDEWEB)

Xu, Songhua [ORNL; Fan, Rukun [University of North Carolina, Chapel Hill; Geng, Weidong [Zhejiang University

2011-04-21

We introduce a novel method for synthesizing dance motions that follow the emotions and contents of a piece of music. Our method employs a learning-based approach to model the music to motion mapping relationship embodied in example dance motions along with those motions' accompanying background music. A key step in our method is to train a music to motion matching quality rating function through learning the music to motion mapping relationship exhibited in synchronized music and dance motion data, which were captured from professional human dance performance. To generate an optimal sequence of dance motion segments to match with a piece of music, we introduce a constraint-based dynamic programming procedure. This procedure considers both music to motion matching quality and visual smoothness of a resultant dance motion sequence. We also introduce a two-way evaluation strategy, coupled with a GPU-based implementation, through which we can execute the dynamic programming process in parallel, resulting in significant speedup. To evaluate the effectiveness of our method, we quantitatively compare the dance motions synthesized by our method with motion synthesis results by several peer methods using the motions captured from professional human dancers' performance as the gold standard. We also conducted several medium-scale user studies to explore how perceptually our dance motion synthesis method can outperform existing methods in synthesizing dance motions to match with a piece of music. These user studies produced very positive results on our music-driven dance motion synthesis experiments for several Asian dance genres, confirming the advantages of our method.

Global optimization framework for solar building design

Silva, N.; Alves, N.; Pascoal-Faria, P.

2017-07-01

The generative modeling paradigm is a shift from static models to flexible models. It describes a modeling process using functions, methods and operators. The result is an algorithmic description of the construction process. Each evaluation of such an algorithm creates a model instance, which depends on its input parameters (width, height, volume, roof angle, orientation, location). These values are normally chosen according to aesthetic aspects and style. In this study, the model's parameters are automatically generated according to an objective function. A generative model can be optimized according to its parameters, in this way, the best solution for a constrained problem is determined. Besides the establishment of an overall framework design, this work consists on the identification of different building shapes and their main parameters, the creation of an algorithmic description for these main shapes and the formulation of the objective function, respecting a building's energy consumption (solar energy, heating and insulation). Additionally, the conception of an optimization pipeline, combining an energy calculation tool with a geometric scripting engine is presented. The methods developed leads to an automated and optimized 3D shape generation for the projected building (based on the desired conditions and according to specific constrains). The approach proposed will help in the construction of real buildings that account for less energy consumption and for a more sustainable world.

Traces across the body: influence of music-dance synchrony on the observation of dance.

Science.gov (United States)

Woolhouse, Matthew Harold; Lai, Rosemary

2014-01-01

In previous studies investigating entrainment and person perception, synchronized movements were found to enhance memory for incidental person attributes. Although this effect is robust, including in dance, the process by which it is actuated are less well understood. In this study, two hypotheses are investigated: that enhanced memory for person attributes is the result of (1) increased gaze time between in-tempo dancers; and/or (2) greater attentional focus between in-tempo dancers. To explore these possible mechanisms in the context of observing dance, an eye-tracking study was conducted in which subjects watched videos of pairs of laterally positioned dancers; only one of the dancers was synchronized with the music, the other being asynchronous. The results were consistent with the first hypothesis-music-dance synchrony gives rise to increased visual inspection times. In addition, there was a preference for upper-body fixations over lower-body fixations across both synchronous and asynchronous conditions. A subsequent, single-dancer eye-tracking study investigated fixations across different body regions, including head, torso, legs and feet. Significantly greater dwell times were recorded for head than torso and legs; feet attracted significantly less dwell time than any other body region. Lastly, the study sought to identify dance gestures responsible for torso- and head-directed fixations. Specifically we asked whether there are features in dance that are specially designed to direct an observer's gaze towards the face-the main "communicative portal" with respect to the transmission of intent, affect and empathy.

Genic control of honey bee dance language dialect.

Science.gov (United States)

Rinderer, T E; Beaman, L D

1995-10-01

Behavioural genetic analysis of honey bee dance language shows simple Mendelian genic control over certain dance dialect differences. Worker honey bees of one parent colony (yellow) changed from round to transition dances for foraging distances of 20 m and from transition to waggle dances at 40 m. Worker bees of the other parent colony (black) made these shifts at 30 m and 90 m, respectively. F1 colonies behaved identically to their yellow parent, suggesting dominance. Progeny of backcrossing between the F1 generation and the putative recessive black parent assorted to four classes, indicating that the dialect differences studied are regulated by genes at two unlinked loci, each having two alleles. Honey bee dance communication is complex and highly integrated behaviour. Nonetheless, analysis of a small element of this behaviour, variation in response to distance, suggests that dance communication is regulated by subsets consisting of simple genic systems.

Full Text Available In this research paper, the author addresses the following four questions: 1 What are the implications of bringing pole dancing into concert dance, not as a caricature or theatrical version of what is performed in strip clubs, but as its own, free-standing art form? 2 In what ways will years of ballet and modern dance training influence the type of dancing that emerges from dancers when poles and other apparatuses are introduced? 3 How can the author create an original pole dancing style and pedagogical methods for teaching it? 4 Who participates in pole fitness classes and how does the demographic change based on location? What about when pole fitness classes are offered in an academic setting? The author shares first-hand experiences of investigating pole dancing in fitness classes, attending performances, engaging in a rehearsal process with highly trained dancers, and teaching pole dancing to movers with a wide range of abilities. The author addresses how research plans changed as she encountered limitations of budget and time constraints. The author also elaborates on the creative process that she engaged in with her thesis cast, collaborators, and supporting designers in the making of Super-beneath, a theatrical dance work that uses five, free-standing poles. She outline the vignettes, overall structure, and narrative of the work. The author then discusses where this research fits into the larger field of pole dancing, and the even larger field of dance. In the final sections of this paper, the author describes her pedagogical practices relating to pole classes, what “practice as research” means to her, and how she would like to continue on this research trajectory in the future.

2010-01-01

Irradiation processing by accelerated electrons is considering one of the most important and useful industrial irradiation treatments. It is depending on two principle attachment elements which are architecture of irradiation building and the accelerator characteristic that was arranged inside irradiation building. Negative environmental measurements were recorded inside the main building and were exceeded the international standards (humidity, air speed, high thermal effects and ozone concentration). The study showed that it is essential to improve the natural environmental standards inside the main irradiation building in order to improve the work environment and to reduce ozone concentration from 220 ppb to international standard. The main goals and advantages were achieved by using environmental architecture (desert architecture) indoor the irradiation building. The work depends on passive solar system which is economic, same architectural elements, comfort / health, and radiation safety, and without mechanical means. The experimental work was accomplished under these modifications. The registered results of various environmental concentrations have proved their normal standards.

2012-01-01

On Tuesday 31 July, CERN’s Restaurant 1 transformed into a dance studio for the duration of a public rehearsal. The performers from the dance troupe of Geneva choreographer Gilles Jobin, CERN’s current artist in residence, presented their 2011 creation, Spider Galaxies. The result: a voyage of bodies suspended between art and science.   Just two months after the choreographer’s “Strangels” invaded the library, the same bodies returned to take over another iconic CERN space: Restaurant 1. While a black floor covering was spread over the dance floor, bordered on three sides by the glass partitions overlooking the terrace, the four dancers warmed up. Gilles Jobin, the first prize winner of the “Collide@CERN” competition held last March in the dance/performance category, briefly introduced the dance that would follow, called Spider Galaxies. The piece, created in 2011, features four dancers moving to music...

Kapoera, a combination of acrobatics and coordinated athletic movement, is believed to have been introduced to South America during the 19th century by transported African slaves. The dance does not involve intentional physical contact, but during 6 months, 3 patients were admitted here for injuries induced by the forceful movements of this dance. 2 underwent exploratory laparotomy that revealed bowel perforations and 1 suffered a comminuted nasal bone fracture. Medical personnel should be familiar with the potential hazards of this dance and martial art.

Sol-gel-processed yttrium-doped NiO as hole transport layer in inverted perovskite solar cells for enhanced performance

2018-05-01

In this work, high-performance inverted planar perovskite solar cells (PSCs) using sol-gel processed Y-doped NiO thin films as hole transport layer (HTL) were demonstrated. Y-doped NiO thin films containing different Y doping concentrations were successfully prepared through a simple sol-gel process. The Y doping could significantly improve the electrical conductivity of NiO thin film, and the photovoltaic performance of Y-doped NiO HTL-based PSC devices outperformed that of the pristine NiO HTL-based device. Notably, the PSC using a 5%Y-NiO HTL exhibited the champion performance with an open-circuit voltage (Voc) of 1.00 V, a short circuit current density (Jsc) of 23.82 mA cm-2, a fill factor (FF) of 68% and a power conversion efficiency (PCE) of 16.31%, resulting in a 27.62% enhancement in PCE in comparison with the NiO device. The enhanced performance of the Y-doped NiO device could be attributed to the improved hole mobility, the high quality compact active layer morphology, the more efficient charge extraction from perovskite absorber as well as the lower recombination probability of charge carriers. Thus, this work provides a simple and effective approach to improve the electrical conductivity of p-type NiO thin films for use as a promising HTL in high performance PSCs.

Intensive practise of sensorimotor skills, such as music and dance, is associated with brain structural plasticity. While the neural correlates of music have been well-investigated, less is known about the neural correlates of dance. Additionally, the gray matter structural correlates of dance versus music training have not yet been directly compared. The objectives of the present study were to compare gray matter structure as measured by surface- and voxel-based morphometry between expert dancers, expert musicians and untrained controls, as well as to correlate gray matter structure with performance on dance- and music-related tasks. Dancers and musicians were found to have increased cortical thickness compared to controls in superior temporal regions. Gray matter structure in the superior temporal gyrus was also correlated with performance on dance imitation, rhythm synchronization and melody discrimination tasks. These results suggest that superior temporal regions are important in both dance- and music-related skills and may be affected similarly by both types of long-term intensive training. This work advances knowledge of the neural correlates of dance and music, as well as training-associated brain plasticity in general. Copyright © 2016 Elsevier B.V. All rights reserved.

Dancing in the 'Contact Zone'

Monica Wulff

2006-09-01

Full Text Available In October 2002 I performed and exhibited Troppo Obscura: A Peepshow of Historical Perversity at the Performance Space as part of the multicultural Arts festival, Carnivale, in Sydney, Australia. Troppo Obscura is a multimedia installation that explores some aspects of the complex relationships between the West and Asia. The work looks at a large range of possibilities, from the colonial gaze through to personal relationships forged through artistic endeavor. This paper—the first of two extended mediations on the topic—focuses on one such personal relationship addressed in the installation, namely that between traditional master mask dancer Ibu Sawitri from Cirebon on the West coast of Java, Indonesia and myself, a Sydney based contemporary dancer and performance artist. Between 1992 and 1999, the year Ibu Sawitri passed away, I spent many long-term visits learning dance and living in Ibu Sawitri’s house in Losari. This essay focuses on Ibu Sawitri’s family and dance background and how she, the younger generation of dancers, the dance context, and the dance itself, have been transformed over time as a result of rapidly changing socio-historical conditions. In the second half of this paper I move the discussion to the broader issues of cross-cultural encounters in what Pratt terms the ‘contact zone’ (1992. This includes looking at dance as an embodied practice and its function in the ‘contact zone’ as well as dealing with Spivak’s debates about the subaltern voice in reference to my telling of Ibu Sawitri’s story, both in the installation and in text. A closer analysis of the dynamics of my dance with Ibu Sawitri in the ‘contact zone’ is addressed here.

Mayers, Lester; Bronner, Shaw; Agraharasamakulam, Sujani; Ojofeitimi, Sheyi

2010-01-01

Tap dance is a unique performing art utilizing the lower extremities as percussion instruments. In a previous study these authors reported decreased injury prevalence among tap dancers compared to other dance and sports participants. No biomechanical analyses of tap dance exist to explain this finding. The purpose of the current pilot study was to provide a preliminary overview of normative peak kinetic and kinematic data, based on the hypothesis that tap dance generates relatively low ground reaction forces and joint forces and moments. Six professional tap dancers performed four common tap dance sequences that produced data captured by the use of a force platform and a five-camera motion analysis system. The mean vertical ground reaction force for all sequences was found to be 2.06+/-0.55 BW. Mean peak sagittal, frontal, and transverse plane joint moments (hip, knee, and ankle) ranged from 0.07 to 2.62 N.m/kg. These small ground reaction forces and joint forces and moments support our hypothesis, and may explain the relatively low injury incidence in tap dancers. Nevertheless, the analysis is highly complex, and other factors remain to be studied and clarified.

Current cancer care increasingly incorporates psychosocial interventions. Cancer patients use dance/movement therapy to learn to accept and reconnect with their bodies, build new self-confidence, enhance self-expression, address feelings of isolation, depression, anger and fear and to strengthen personal resources. To update the previously published review that examined the effects of dance/movement therapy and standard care versus standard care alone or standard care and other interventions on psychological and physical outcomes in patients with cancer. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 6), MEDLINE (OvidSP, 1950 to June week 4, 2014), EMBASE (OvidSP, 1980 to 2014 week 26), CINAHL (EBSCOhost, 1982 to July 15 2014), PsycINFO (EBSCOhost, 1806 to July 15 2014), LILACS (Virual Health Library, 1982 to July 15 2014), Science Citation Index (ISI, 1974 to July 15 2014), CancerLit (1983 to 2003), International Bibliography of Theatre and Dance (1989 to July 15 2014), the National Research Register (2000 to September 2007), Proquest Digital Dissertations, ClinicalTrials.gov, and Current Controlled Trials (all to July 15 2014). We handsearched dance/movement therapy and related topics journals, reviewed reference lists and contacted experts. There was no language restriction. We included all randomized and quasi-randomized controlled trials of dance/movement therapy interventions for improving psychological and physical outcomes in patients with cancer. We considered studies only if dance/movement therapy was provided by a formally trained dance/movement therapist or by trainees in a formal dance/movement therapy program. Two review authors independently extracted the data and assessed the methodological quality, seeking additional information from the trial researchers when necessary. Results were presented using standardized mean differences. We identified one new trial for inclusion in this update. In

Falls are one of the most common health problems among older people and pose a major economic burden on health care systems. Exercise is an accepted stand-alone fall prevention strategy particularly if it is balance training or regular participation in Tai chi. Dance shares the 'holistic' approach of practices such as Tai chi. It is a complex sensorimotor rhythmic activity integrating multiple physical, cognitive and social elements. Small-scale randomised controlled trials have indicated that diverse dance styles can improve measures of balance and mobility in older people, but none of these studies has examined the effect of dance on falls or cognition. This study aims to determine whether participation in social dancing: i) reduces the number of falls; and ii) improves cognitive functions associated with fall risk in older people. A single-blind, cluster randomised controlled trial of 12 months duration will be conducted. Approximately 450 participants will be recruited from 24 self-care retirement villages that house at least 60 residents each in Sydney, Australia. Village residents without cognitive impairment and obtain medical clearance will be eligible. After comprehensive baseline measurements including physiological and cognitive tests and self-completed questionnaires, villages will be randomised to intervention sites (ballroom or folk dance) or to a wait-listed control using a computer randomisation method that minimises imbalances between villages based on two baseline fall risk measures. Main outcome measures are falls, prospectively measured, and the Trail Making cognitive function test. Cost-effectiveness and cost-utility analyses will be performed. This study offers a novel approach to balance training for older people. As a community-based approach to fall prevention, dance offers older people an opportunity for greater social engagement, thereby making a major contribution to healthy ageing.

Significant progress has been made on maximising passive solar heat gains to building spaces in winter. Control of the space heating in these applications is complicated due to the lagging influence of the useful solar heat gain coupled with the wide range of construction materials and heating system choices. Additionally, and in common with most building control applications, there is a need to develop control solutions that permit simple and transparent set-up and commissioning procedures. This paper addresses the development and testing of a quasi-adaptive fuzzy logic control method that addresses these issues. The controller is developed in two steps. A feed-forward neural network is used to predict the internal air temperature, in which a singular value decomposition (SVD) algorithm is used to remove the highly correlated data from the inputs of the neural network to reduce the network structure. The fuzzy controller is then designed to have two inputs: the first input being the error between the set-point temperature and the internal air temperature and the second the predicted future internal air temperature. The controller was implemented in real-time using a test cell with controlled ventilation and a modulating electric heating system. Results, compared with validated simulations of conventionally controlled heating, confirm that the proposed controller achieves superior tracking and reduced overheating when compared with the conventional method of control.

Full Text Available Space cooling and heating always tends to be a major part of the primary energy usage. By using fossil fuel electricity for these purposes, the situation becomes even worse. One of the major electricity consumptions in India is air conditioning. There are a lot of different technologies and few researchers have come up with a debate between solar absorption cooling and PV electric cooling. In a previous paper, PV electric cooling was studied and now as a continuation, this paper focuses on solar thermal absorption cooling systems and their application in commercial/office buildings in India. A typical Indian commercial building is taken for the simulation in TRNSYS. Through this simulation, the feasibility and operational strategy of the system is analysed, after which parametric study and economic analysis of the system is done. When compared with the expenses for a traditional air conditioner unit, this solar absorption cooling will take 13.6 years to pay back and will take 15.5 years to payback the price of itself and there after all the extra money are savings or profit.  Although the place chosen for this study is one of the typical tropical place in India, this payback might vary with different places, climate and the cooling demand.

Degradation of historical stained glass windows is mainly caused by acid attack enhanced by humidity and pollutants. Accordingly, their preventive conservation should include environmental evaluation. Maumejean's stained glass windows (c 1940) of two buildings located at downtown Madrid have been monitored by sol-gel sensors of acidity and temperature. The philosophy was the application of innovative glassy sol-gel sensors to assess the conservation conditions of stained glass windows, i.e. modern materials for preservation of historical materials. Conservation conditions (environmental acidity and temperature) of restored and non-restored stained glass windows have been recorded throughout 13 months. The main contributing parameter to outdoor acidity is proximity to road traffic, which produces acid species able to diminish two units of pH with respect to neutral conditions. This acid environment affects both sides of stained glass windows, even in those protected with a glazing system, which allows natural ventilation. Other contributing parameters to increase the air acidity were facade orientation, sensor position, distance to pollutants sources, human interaction and uncontrolled ventilation. (Author)

Why, when and where did honey bee dance communication evolve?

Directory of Open Access Journals (Sweden)

Robbie eI'Anson Price

2015-11-01

Full Text Available Honey bees (Apis sp. are the only known bee genus that uses nest-based communication to provide nest-mates with information about the location of resources, the so-called dance language. Successful foragers perform waggle dances for high quality food sources and suitable nest-sites during swarming. However, since many species of social insects do not communicate the location of resources to their nest-mates, the question of why the dance language evolved is of ongoing interest. We review recent theoretical and empirical research into the ecological circumstances that make dance communication beneficial in present day environments. This research suggests that the dance language is most beneficial when food sources differ greatly in quality and are hard to find. The dances of extant honey bee species differ in important ways, and phylogenetic studies suggest an increase in dance complexity over time: species with the least complex dance were the first to appear and species with the most complex dance are the most derived. We review the fossil record of honey bees and speculate about the time and context (foraging vs. swarming in which spatially referential dance communication might have evolved. We conclude that there are few certainties about when the dance language first appeared; dance communication could be older than 40 million years and, thus, predate the genus Apis, or it could be as recent as 20 million years when extant honey bee species diverged during the early Miocene. The most parsimonious scenario assumes it evolved in a sub-tropical to temperate climate, with patchy vegetation somewhere in Eurasia.

Traces across the body: influence of music-dance synchrony on the observation of dance

Science.gov (United States)

Woolhouse, Matthew Harold; Lai, Rosemary

2014-01-01

In previous studies investigating entrainment and person perception, synchronized movements were found to enhance memory for incidental person attributes. Although this effect is robust, including in dance, the process by which it is actuated are less well understood. In this study, two hypotheses are investigated: that enhanced memory for person attributes is the result of (1) increased gaze time between in-tempo dancers; and/or (2) greater attentional focus between in-tempo dancers. To explore these possible mechanisms in the context of observing dance, an eye-tracking study was conducted in which subjects watched videos of pairs of laterally positioned dancers; only one of the dancers was synchronized with the music, the other being asynchronous. The results were consistent with the first hypothesis—music-dance synchrony gives rise to increased visual inspection times. In addition, there was a preference for upper-body fixations over lower-body fixations across both synchronous and asynchronous conditions. A subsequent, single-dancer eye-tracking study investigated fixations across different body regions, including head, torso, legs and feet. Significantly greater dwell times were recorded for head than torso and legs; feet attracted significantly less dwell time than any other body region. Lastly, the study sought to identify dance gestures responsible for torso- and head-directed fixations. Specifically we asked whether there are features in dance that are specially designed to direct an observer’s gaze towards the face—the main “communicative portal” with respect to the transmission of intent, affect and empathy.

Full Text Available Dye-sensitized solar cell (DSSC is one of the very promising alternative renewable energy sources to anticipate the declination in the fossil fuel reserves in the next few decades and to make use of the abundance of intensive sunlight energy in tropical countries like Indonesia. In the present study, TiO2 nanoparticles of different nanocrystallinity was synthesized via sol−gel process with various water to inorganic precursor ratio (Rw of 0.85, 2.00 and 3.50 upon sol preparation, followed with subsequent drying, conventional annealing and post-hydrothermal treatments. The resulting nanoparticles were integrated into the DSSC prototype and sensitized with an organic dye made of the extract of red onion. The basic performance of the fabricated DSSC has been examined and correlated to the crystallite size and band gap energy of TiO2 nanoparticles. It was found that post-hydrothermally treated TiO2 nanoparticles derived from sol of 2.00 Rw, with the most enhanced nanocrystalline size of 12.46 nm and the lowest band gap energy of 3.48 eV, showed the highest open circuit voltage (Voc of 69.33 mV.

The influence of sensorimotor experience on the aesthetic evaluation of dance across the life span.

Science.gov (United States)

Kirsch, Louise P; Cross, Emily S

2018-01-01

Understanding how action perception, embodiment, and emotion interact is essential for advancing knowledge about how we perceive and interact with each other in a social world. One tool that has proved particularly useful in the past decade for exploring the relationship between perception, action, and affect is dance. Dance is, in its essence, a rich and multisensory art form that can be used to help answer not only basic questions about social cognition but also questions concerning how aging shapes the relationship between action perception, and the role played by affect, emotion, and aesthetics in social perception. In the present study, we used a 1-week physical and visual dance training paradigm to instill varying degrees of sensorimotor experience among non-dancers from three distinct age groups (early adolescents, young adults, and older adults). Our aim was to begin to build an understanding of how aging influences the relationship between action embodiment and affective (or aesthetic) value, at both brain and behavioral levels. On balance, our results point toward a similar positive effect of sensorimotor training on aesthetic evaluations across the life span on a behavioral level, but to rather different neural substrates supporting implicit aesthetic judgment of dance movements at different life stages. Taken together, the present study contributes valuable first insights into the relationship between sensorimotor experience and affective evaluations across ages, and underscores the utility of dance as a stimulus and training intervention for addressing key questions relevant to human neuroscience as well as the arts and humanities. © 2018 Elsevier B.V.

MAGA MAGAZINOVIC: THE MAIN CONCEPTS OF MODERN DANCE

Directory of Open Access Journals (Sweden)

Milos Marijan

2018-02-01

Full Text Available Marija Maga Magazinovic (Užice,1882- Belgrade, 1968, a choreographer, dancer, modern dance theorist, philosopher, feminist, librarian and journalist, was the founder of modern dance in Serbia. In her efforts to introduce modern dance, Magazinovic demanded emancipation of art, “pure” dance, a beauty of simple movements, which had no need for story, scenography, costume, even music, nothing but naked dancer’s body. Maga, who graduated philosophy at the Belgrade University in 1904, and was a journalist by vocation, working as the first woman journalist in the daily newspaper “Politica” as a columnist, also fought for women’s rights and emancipation. By bringing modern artistic view into the patriarchal Serbian society, she contributed to the social and cultural development, and to the understanding and adopting of the modern dance at the very time when it was developed and brought on stage in the West. Stemmed from the schools of Max Reinhardt and ballet school of Isadora Duncan, she brought their views and pedagogical methods to Serbia when she returned from Berlin and Munich to Belgrade, where she opened the first school of modern dance in 1910. She was the first to advocate for the necessity of female education, particularly of engaging girls in doing rhythmic gymnastics and dance as a form of bodily and spiritual education. Given that Marija Maga Magazinovic was the first who opened the door for the progress and changes in the fields of dance and women’s rights by bringing concepts of those movements, in which she directly participated, to Serbia, these concepts had to be explained. Therefore, the main goal of the paper is to examine these concepts, such as modern dance, rhythmic gymnastic, body culture, Ausdruckstanz, expressionism, and women emancipation, which is crucial if we want to understand early period of modern dance development, and to understand Magazinovic’s efforts and achievements and her place and historical

FORMING PROFESSIONAL SKILLS OF THE PROSPECTIVE HEADS OF CHILDREN'S DANCE GROUPS DURING THE CHOREOGRAPHIC ACTIVITIES IN THE COURSE "FOLK DANCE THEORY AND METHODOLOGY"

Full Text Available The article highlights the urgent problem of contemporary art pedagogy – involvement to training future professional choreographic traditions of different nations. Addressing to this problem is caused by a number of socio-political events in Ukraine, mainstreaming of national and international education, integration of Ukrainian education with the European educational space, intensive development of domestic students’ intercultural communication with young people from different countries, which is the basis for updating national art education. Prospective choreographers, who are being training at pedagogical universities to manage children's dance groups, should actively be involved into creating their own productions of folk dance various genres. It promotes the formation of choreographers’ professional competence and pedagogical skills. The development of Georgian "Lezginka" is proposed – a joint creative work of the teacher and students who get higher education degree in SHEE “Donbass State Pedagogical University” (Bachelor's Degree. Development of the dance contains schematic drawings of dance figures, it is recommended for use in forming choreographers’ professional skills while studying the course "Folk Dance Theory and Methodology". The author admits that folklore material requires a cautious, respectful attitude. Therefore, modern folk stage dances are integrally to combine traditional choreographic manner with its new interpretations. The author believes the actual capture of different nations’ choreographic culture improves intercultural youth communication; involves future professionals into the traditions of different nations; form professional skills of managers of children’s dance groups. The author concluded that a dance always reflects consciousness of different nations; future choreographers should be aware of characteristic features of dances of different world nations so that on the basis of traditional

Full Text Available The fabrication of environmental-friendly Cu2ZnSnS4 (CZTS thin films with pure kesterite phase is always a challenge to researchers in the field of solar cells. We introduce a simple non-vacuum sol-gel method to fabricate kesterite CZTS films. Ethylenediamine is used as the chelating agent and stabilizer and plays an important role in preparing stable precursor. X-ray diffraction, Raman and scanning electron microscopy studies suggest that the microstructure and optical properties of CZTS films depend strongly on annealing temperatures. The temperature dependence of conductivity of 500 °C annealed CZTS film shows that the Mott law dominates in the low temperature region and thermionic emission is predominant at high temperatures.

Bernardi, Nicolò F; Bellemare-Pepin, Antoine; Peretz, Isabelle

2018-05-06

We investigated whether dancing influences the emotional response to music, compared to when music is listened to in the absence of movement. Forty participants without previous dance training listened to "groovy" and "nongroovy" music excerpts while either dancing or refraining from movement. Participants were also tested while imitating their own dance movements, but in the absence of music as a control condition. Emotion ratings and ratings of flow were collected following each condition. Dance movements were recorded using motion capture. We found that the state of flow was increased specifically during spontaneous dance to groovy excerpts, compared with both still listening and motor imitation. Emotions in the realms of vitality (such as joy and power) and sublimity (such as wonder and nostalgia) were evoked by music in general, whether participants moved or not. Significant correlations were found between the emotional and flow responses to music and whole-body acceleration profiles. Thus, the results highlight a distinct state of flow when dancing, which may be of use to promote well-being and to address certain clinical conditions. © 2018 New York Academy of Sciences.

Spirit Near 'Stapledon' on Sol 1802

Science.gov (United States)

2009-01-01

NASA Mars Exploration Rover Spirit used its navigation camera for the images assembled into this full-circle view of the rover's surroundings during the 1,802nd Martian day, or sol, (January 26, 2009) of Spirit's mission on the surface of Mars. South is at the center; north is at both ends. Spirit had driven down off the low plateau called 'Home Plate' on Sol 1782 (January 6, 2009) after spending 12 months on a north-facing slope on the northern edge of Home Plate. The position on the slope (at about the 9-o'clock position in this view) tilted Spirit's solar panels toward the sun, enabling the rover to generate enough electricity to survive its third Martian winter. Tracks at about the 11-o'clock position of this panorama can be seen leading back to that 'Winter Haven 3' site from the Sol 1802 position about 10 meters (33 feet) away. For scale, the distance between the parallel wheel tracks is about one meter (40 inches). Where the receding tracks bend to the left, a circular pattern resulted from Spirit turning in place at a soil target informally named 'Stapledon' after William Olaf Stapledon, a British philosopher and science-fiction author who lived from 1886 to 1950. Scientists on the rover team suspected that the soil in that area might have a high concentration of silica, resembling a high-silica soil patch discovered east of Home Plate in 2007. Bright material visible in the track furthest to the right was examined with Spirit's alpha partical X-ray spectrometer and found, indeed, to be rich in silica. The team laid plans to drive Spirit from this Sol 1802 location back up onto Home Plate, then southward for the rover's summer field season. This view is presented as a cylindrical projection with geometric seam correction.

Evaluating Different Green School Building Designs for Albania: Indoor Thermal Comfort, Energy Use Analysis with Solar Systems

Science.gov (United States)

Dalvi, Ambalika Rajendra

Improving the conditions of schools in many parts of the world is gradually acquiring importance. The Green School movement is an integral part of this effort since it aims at improving indoor environmental conditions. This would in turn, enhance student- learning while minimizing adverse environmental impact through energy efficiency of comfort-related HVAC and lighting systems. This research, which is a part of a larger research project, aims at evaluating different school building designs in Albania in terms of energy use and indoor thermal comfort, and identify energy efficient options of existing schools. We start by identifying three different climate zones in Albania; Coastal (Durres), Hill/Pre-mountainous (Tirana), mountainous (Korca). Next, two prototypical school building designs are identified from the existing stock. Numerous scenarios are then identified for analysis which consists of combinations of climate zone, building type, building orientation, building upgrade levels, presence of renewable energy systems (solar photovoltaic and solar water heater). The existing building layouts, initially outlined in CAD software and then imported into a detailed building energy software program (eQuest) to perform annual simulations for all scenarios. The research also predicted indoor thermal comfort conditions of the various scenarios on the premise that windows could be opened to provide natural ventilation cooling when appropriate. This study also estimated the energy generated from solar photovoltaic systems and solar water heater systems when placed on the available roof area to determine the extent to which they are able to meet the required electric loads (plug and lights) and building heating loads respectively. The results showed that there is adequate indoor comfort without the need for mechanical cooling for the three climate zones, and that only heating is needed during the winter months.

Dance therapy is a physical activity that can lead to balance improvement in older adults. The aim of the study was to evaluate the effects of dance therapy on balance and risk of falls in older women. Twenty-four older women (mean age 66.4 years old) attended dance sessions for three months. Pretest/posttests were completed using the Postural Stability Test, the Limits of Stability Test, and the Fall Risk Test M-CTSIB. Results showed the Limits of Stability Test was significantly higher (17.5%) after dance classes. Regular use of dance therapy shows promise in improving balance by increasing the limits of stability.

Hip Hop Dance Experience Linked to Sociocognitive Ability.

Bonny, Justin W; Lindberg, Jenna C; Pacampara, Marc C

2017-01-01

Expertise within gaming (e.g., chess, video games) and kinesthetic (e.g., sports, classical dance) activities has been found to be linked with specific cognitive skills. Some of these skills, working memory, mental rotation, problem solving, are linked to higher performance in science, technology, math, and engineering (STEM) disciplines. In the present study, we examined whether experience in a different activity, hip hop dance, is also linked to cognitive abilities connected with STEM skills as well as social cognition ability. Dancers who varied in hip hop and other dance style experience were presented with a set of computerized tasks that assessed working memory capacity, mental rotation speed, problem solving efficiency, and theory of mind. We found that, when controlling for demographic factors and other dance style experience, those with greater hip hop dance experience were faster at mentally rotating images of hands at greater angle disparities and there was a trend for greater accuracy at identifying positive emotions displayed by cropped images of human faces. We suggest that hip hop dance, similar to other more technical activities such as video gameplay, tap some specific cognitive abilities that underlie STEM skills. Furthermore, we suggest that hip hop dance experience can be used to reach populations who may not otherwise be interested in other kinesthetic or gaming activities and potentially enhance select sociocognitive skills.

Orfi J.

2012-10-01

Full Text Available Energy needed for cooling residential and industrial buildings in hot weather countries is the major issue. The period needed for cooling or comfort conditions in those countries exceeds five months and outdoor temperature reaches more than 40 °C. Also, the solar intensity usually high and can reach about one kW per m2. Hence, any attempt to reduce the effect of solar energy on the cooling load is worthy to investigate. The present work analyzes using artificial, naturally ventilated, shading covers to reduce the effect of solar energy. Analytical and numerical analyzes were performed on the effect of adding a ventilated cover to walls and roof exposed to the solar energy.

Musical meaning and social significance : techno triggers for dancing

OpenAIRE

Gadir, Tami Ester

2014-01-01

Electronically-produced dance music has only recently achieved as much visibility in the global pop music industry as ‘live’ or instrumental pop. Yet the fascination of cultural scholars and sociologists with dance music predates its rise as a product of mass culture. Much of this interest derives from early associations of dance music with marginalised groups and oppositional ideologies. It therefore follows that many explorations of dance music focus on the ways in which tech...

French Society Abroad: The Popularization of French Dance throughout Europe, 1600-1750

Directory of Open Access Journals (Sweden)

Adam Paul Rinehart

2017-09-01

Full Text Available This paper explores the dissemination of French dance, dance notation, and dance music throughout Europe, and it explains the reasons why French culture had such an influence on other European societies from 1600-1750. First, the paper seeks to prove that King Louis XIV played a significant role in the outpour of French dance and the arts. Next, the paper discusses prominent French writers of dance notation who influenced the spread of French dance literature and training throughout Europe. Finally, the paper delineates European composers and their involvement in the development and production of French dance music. Using academic, peer-reviewed journal articles, books, and other scholarly sources, this paper seeks to accurately present the information in an orderly fashion. The paper contains visual evidence of dance and music notation to assist the reader in understanding the subject matter. Additionally, theories of contemporary authors as well as authors from the time period are discussed to present concrete evidence. The two main types of dance discussed in the paper are ballroom and court dances, which were prominent within the French royal court. One major finding of the research is the fact that French court and ballroom dances were specifically designed to communicate the power and prestige of King Louis XIV; consequently, other European countries were influenced to strive for similar prestige. Another finding is that many forms of French dance notation were translated and published in other countries, which increased the use of French dance throughout Europe. Musically, European composers such as Handel and Mozart included elements of French dance music in their compositions, and thus played a significant role in prevalence of French dance music throughout Europe. Overall, this paper proves that French dance received wide recognition due to political influence, availability of dance notation, and the involvement of prominent composers.

During the last three years under the sponsorship of the DOE Solar Passive Division, the University of Dayton Research Institute (UDRI) has investigated four phase change material (PCM) systems for utility in thermal energy storage for solar passive heating and cooling applications. From this research on the basis of cost, performance, containment, and environmental acceptability, we have selected as our current and most promising series of candidate phase change materials, C-15 to C-24 linear crystalline alkyl hydrocarbons. The major part of the research during this contract period was directed toward the following three objectives. Find, test, and develop low-cost effective phase change materials (PCM) that melt and freeze sharply in the comfort temperature range of 73--77{degree}F for use in solar passive heating and cooling of buildings. Define practical materials and processes for fire retarding plasterboard/PCM building products. Develop cost-effective methods for incorporating PCM into building construction materials (concrete, plasterboard, etc.) which will lead to the commercial manufacture and sale of PCM-containing products resulting in significant energy conservation.

Neurological implications and neuropsychological considerations on folk music and dance.

Science.gov (United States)

Sironi, Vittorio A; Riva, Michele A

2015-01-01

Neurological and neuropsychological aspects of folk music and traditional dance have been poorly investigated by historical and scientific literature. Some of these performances could be indeed the manifestation of latent pathological conditions or the expression of liberation rituals. This chapter aimed at analyzing the relationships between traditional dance, folk music, and neurological and psychiatric disorders. Since ancient times, dance has been used in the individual or collective as treatment of some diseases, including epilepsy and movement disorders (dyskinesia, chorea, etc.). Dionysia in Ancient Greece, St. Vitus dance in the Middle Age, tarantism and other traditional dances of southern Italy and of non-Western countries might be credited as curative rituals of these neurological and psychiatric conditions. During the nineteenth century, dance was also used for the treatment of psychiatric patients; the relationship between dance and insanity could also be reflected in classical ballets and music of that period. Nowadays, neuropsychiatric manifestations could also be evidenced in modern dances (mass fainting at rock concerts, flash mobs); some ballroom dances are commonly used for the rehabilitation of patients suffering from neurodegenerative and psychiatric conditions. Interdisciplinary research on these subjects (ethnomusicology and cultural anthropology, clinical neurology and dynamic psychology, neuroradiology and neurophysiology, and socioneurology and neuromusicology) should be increased. © 2015 Elsevier B.V.

Daylight and solar control in buildings. General evaluation and optimization of a new angle selective glazing facade

Energy Technology Data Exchange (ETDEWEB)

Frontini, Francesco

2011-07-01

Buildings account for almost 40% of the overall energy consumption in Europe. For the future energy scenarios, the building envelope, especially the facades, becomes really important as it provides the necessary area for the installation of PV modules or solar collectors to produce energy, using renewable energy sources. A new multifunctional building integrated photovoltaic (BIPV) glazed facade for this application is presented here. The new angle-selective see through facade combines four important tasks in one element: solar control, glare protection, visual contact and electricity generation. Mathematical analysis and complex simulations with the software Radiance are performed to optimize the geometry and to assess the visual impact and optical properties of the new window. In order to evaluate the impact of the new facade in building spaces a new method for modelling the total solar energy transmittance, in building energy simulations software, for complex glazing facades is presented. The new black-box-model (BBM) is implemented into ESP-r software and is validated. The BBM is used to assess the impact of modelling accurately the g-value of complex facade within building simulation. It is shown that the new method can significantly increase the accuracy of heating/cooling loads and room temperatures. (orig.)

Choreographing lived experience: dance, feelings and the storytelling body.

Although narrative-based research has been central to studies of illness experience, the inarticulate, sensory experiences of illness often remain obscured by exclusively verbal or textual inquiry. To foreground the body in our investigation of subjective and intersubjective aspects of eating disorders, we-a medical anthropologist and a contemporary dance choreographer-designed a collaborative project, in which we studied the experiences of women who had eating disorders, through eight weeks of integrating dance practice-based, discussion-based and interview-based research. Grounded in the participants' own reflections on choreographing, dancing and watching others perform solos about their eating disordered experiences, our analysis examines the types of knowledge the participants used in choreographing their dance works, and the knowledge that they felt the dance enabled them to convey. We find that the participants consistently spoke of feeling as guiding their choreographic processes; they also said the experiences they conveyed through their dance works were centred in feelings, rather than in practices or events. Through dance, the participants said they could communicate experiences that would have remained unspoken otherwise. Yet, notably, dance practice also enabled participants to begin defining and describing their experiences verbally. We suggest, therefore, that through engaging participants in contemporary dance practice, we can begin to identify and address embodied experiences of illness and recovery that may be silenced in speech or writing alone.

Traces Across the Body: The Influence of Music-Dance Synchrony on the Observation of Dance

Directory of Open Access Journals (Sweden)

Matthew Harold Woolhouse

2014-12-01

Full Text Available In previous studies investigating entrainment and person perception, synchronized movements were found to enhance memory for incidental person attributes. Although this effect is robust, including in dance, the process by which it is actuated are less well understood. In this study, two hypotheses are investigated: that enhanced memory for person attributes is the result of (1 increased gaze time between in-tempo dancers, and/or (2 greater attentional focus between in-tempo dancers. To explore these possible mechanisms in the context of observing dance, an eye-tracking study was conducted in which subjects watched videos of pairs of laterally positioned dancers; only one of the dancers was synchronized with the music, the other being asynchronous. The results were consistent with the first hypothesis—music-dance synchrony gives rise to increased visual inspection times. In addition, there was a preference for upper-body fixations over lower-body fixations across both synchronous and asynchronous conditions. A subsequent, single-dancer eye-tracking study investigated fixations across different body regions, including head, torso, legs and feet. Significantly greater dwell times were recorded for head than torso and legs; feet attracted significantly less dwell time than any other body region. Lastly, the study sought to identify dance gestures responsible for torso- and head-directed fixations. Specifically we asked whether there are features in dance that are specially designed to direct an observer’s gaze towards the face—the main communicative portal with respect to the transmission of intent, affect and empathy.

ESTIMATION OF SOLAR ENERGY ON VERTICAL 3D BUILDING WALLS ON CITY QUARTER SCALE

Directory of Open Access Journals (Sweden)

F. Jaugsch

2016-10-01

Full Text Available In urban areas, solar energy is one promising source of renewable energy to achieve the EU parliament’s goal of reducing CO2 emissions by 20 % compared to 1990. Although annual radiation on vertical walls is lower than that on roof surfaces, they are larger in area and, therefore may contribute to energy production. On the other hand, the modelling of shadowing effects is cost intensive in an complex urban environment. Here we present a method for the calculation of solar potential on vertical walls for simple 2D maps with additional building height information. We introduced observer point columns that enable a fast decision whether a whole vertical set of observer points is illuminated or not. By the introduction of a maximum shade length, we reduce processing time in ArcGIS. 206,291 points of 130 buildings have been analysed in time steps of 15 minutes resulting in 15 769 pairs of solar angles. Results disprove the potential of vertical walls serving to fill the winter gap of roof mounted solar energy plants. Best wall orientation for the deployment of solar panels are west and east in summer, whereas it is southeast in winter.

'Eco-house 99' - Full-scale demonstration of solar walls with building integrated heat storages

Energy Technology Data Exchange (ETDEWEB)

Hummelshoej, R.M.; Rahbek, J.E. [COWI Consulting Engineers and Planners AS (Denmark)

2000-07-01

A critical issue for solar systems in northern latitudes is the economic profitability. It is often said that the techniques for solar utilisation are expensive and unprofitable. This is, however, not always the case. A new project with 59 low energy terrace houses was carried out in Kolding, Denmark. The houses are designed as ecological buildings with emphasis on total economy based on low operation and maintenance costs, energy conservation and passive/hybrid solar utilisation. Besides direct solar gain through windows, each house has a solar wall of 6-8.5 m{sup 2} on the south facade. The solar walls are used both for heating of ventilation air and for space heating. The solar walls deliver heat to the dwellings during the heating season. To optimise the energy utilisation from the solar walls, the energy is stored internally in building integrated heat storages. Two different new types of prefabricated heat storages are built into the houses. One is an internal concrete wall with embedded ventilation pipes, and the other is a hollow concrete element with integrated stone bed. The heat storages are mainly designed to store solar energy from the day to the evening and the night. Because the solar walls and the heat storages have been a part of the design process from the start, the additional expenses are as low as 30-140 Euro/m{sup 2} solar wall compared with the alternative facade. This is far less than what it costs to add a solar wall on an existing building. Measurements over one year show that the yield of the solar walls is in the range of 115-125 kWh/m{sup 2}/year as expected. With the actual financing, the annual payment of the additional expenses for the solar systems is between 1-6 Euro/m{sup 2} solar wall, while the annual savings are about 5 Euro/year/m{sup 2} (with an energy price of 0.042 Euro/kWh). Dependent on which alternative facade construction the solar wall system is compared with, the profit of the system is in the range of 1 to +4 Euro

Performance advancement of solar air-conditioning through integrated system design for building

International Nuclear Information System (INIS)

Fong, K.F.; Lee, C.K.

2014-01-01

This study is to advance the energy performance of solar air-conditioning system through appropriate component integration from the absorption refrigeration cycle and proper high-temperature cooling. In the previous studies, the solar absorption air-conditioning using the working pair of water – lithium bromide (H 2 O–LiBr) is found to have prominent primary energy saving than the conventional compression air-conditioning for buildings in the hot-humid climate. In this study, three integration strategies have been generated for solar cooling, namely integrated absorption air-conditioning; integrated absorption-desiccant air-conditioning; and integrated absorption-desiccant air-conditioning for radiant cooling. To realize these ideas, the working pair of ammonia – water (NH 3 –H 2 O) was used in the absorption cycle, rather than H 2 O–LiBr. As such, the evaporator and the condenser can be separate from the absorption refrigeration cycle for the new configuration of various integrated design alternatives. Through dynamic simulation, the year-round primary energy saving of the proposed integration strategies for solar NH 3 –H 2 O absorption air-conditioning systems could be up to 50.6% and 25.5%, as compared to the conventional compression air-conditioning and the basic solar H 2 O–LiBr absorption air-conditioning respectively. Consequently, carbon reduction of building air-conditioning can be achieved more effectively through the integrated system design in the hot and humid cities. - Highlights: • Three integration strategies, IAAU, IADAU and IADAU-RC, are proposed to advance solar air-conditioning. • NH 3 –H 2 O is adopted for absorption refrigeration instead of H 2 O–LiBr. • Separate evaporator and condenser, desiccant cooling and radiant cooling are designed for IADAU-RC. • IADAU-RC can have 50.6% primary energy saving against the conventional air-conditioning

Analysis of potential energy, economic and environmental savings in residential buildings: Solar collectors combined with microturbines

International Nuclear Information System (INIS)

Suárez, I.; Prieto, M.M.; Fernández, F.J.

2013-01-01

Highlights: ► Centralization of energy systems for a group of buildings improves profitability. ► Thermal solar systems are economically interesting even in low radiation locations. ► Regulations currently in force determine the feasibility of high efficiency energy systems. - Abstract: This paper presents an analysis of a combined solar-cogeneration installation for providing energy services in a set of four residential buildings. Different configurations as regards the number of collectors and their orientation, the number of buildings grouped together, the type of microturbines used in the cogeneration system and their daily and annual operating period are studied from the legal, economic and environmental perspectives. The installation that fulfils the minimum requirements of the solar system coverage and the cogeneration system efficiency currently in force, and simultaneously leads to the highest energy, economic and environmental savings is the one that integrates both technologies and centralises the installation for the four buildings together. A payback period lower than 8 years is obtained that makes this investment recommendable, but it is also concluded that maintaining the existing subsidies for these technologies and lowering the costs of the equipment, are essential factors to ensure the feasibility of this type of installations

Tangled roots: Kalenda and other neo-African dances in the circum-Caribbean

Directory of Open Access Journals (Sweden)

Julian Gerstin

2004-01-01

Full Text Available Investigates descriptions of Afro-Caribbean dances in early chronicles and historical material. Author focuses on choreography, as well as on musical instruments and their use. He pays special attention to descriptions of the Martinican kalenda dance. He discusses descriptions from the 18th c. of black Caribbean dance in French and other colonies, by priests and others, of the kalenda as a couple dance within a ring, and descriptions of other widespread early dances in the Caribbean, such as chica. Author notes that in these early descriptions the authors focus obsessively on eroticism, thus simplifying and exaggerating the dances as sexual, and ignoring their variety. Further, he analyses early chronicles on other widespread dances in the circum-Caribbean, such as stick-fighting dances, bamboula, djouba, and belair, comparing with present-day Caribbean dances, and on "challenge dancing" involving a dance soloist "challenged" by a lead drummer, found, for instance, in kalenda and rumba. In addition, the author focuses on the dances' musical accompaniment by drums, and the drum types and methods, specifically transverse drumming and drumming with sticks on the side of the drum, found today in kalenda, and other Caribbean styles. He points at the inaccuracy of some chronicles, mixing up dance names, and recurring superficiality and stereotypes. He nonetheless concludes from them that slaves from the Congo/Angola region probably played a crucial role in forming these early dance styles, and that their spread was connected with French colonialism and slavery and migrations from (once French colonies. He describes probable Congolese/Angolan influences, such as pelvic isolation, challenge dances, couple dancing within a circle, and transverse drumming, but indicates that these are over time combined with other African and other influences.

Lastufka, Erica; Casadei, Diego

2017-08-01

Advances in the study of coronal electron-accelerating regions have so far been limited by the dynamic range of X-ray instruments. A quick and economical alternative to desirable focusing optics technology is stereo observation. The micro-satellite MiSolFA (Micro Solar-Flare Apparatus) is designed both as a stand-alone X-ray imaging spectrometer and a complement to the Spectrometer/Telescope for Imaging X-rays (STIX) mission. These instruments will be the first pair of cross-calibrated X-ray imaging spectrometers to look at solar flares from very different points of view. MiSolFA will achieve indirect imaging between 10 and 60 keV and provide spectroscopy up to 100 keV, equipped with grids producing moiré patterns in a similar way to STIX. New manufacturing techniques produce gold gratings on a graphite or silicon substrate, with periods ranging from 15 to 225 micrometers, separated by a distance of 15.47 cm, to achieve a spatial resolutions from 10" to 60" (as compared to RHESSI's separation of 150 cm and 1" resolution). We present the progress of the imager design, the performance of the first prototypes, and reach out to the community for further scientific objectives to consider in optimizing the final design.

2011-08-01

Full Text Available Abstract Background Structured physical activity (PA programs are well positioned to promote PA among youth, however, little is known about these programs, particularly dance classes. The aims of this study were to: 1 describe PA levels of girls enrolled in dance classes, 2 determine the contribution of dance classes to total moderate-to-vigorous physical activity (MVPA, and 3 compare PA between days with a dance class (program days and days without a dance class (non-program days. Methods Participants were 149 girls (11-18 years enrolled in dance classes in 11 dance studios. Overall PA was assessed with accelerometry for 8 consecutive days, and girls reported when they attended dance classes during those days. The percent contribution of dance classes to total MVPA was calculated, and data were reduced to compare PA on program days to non-program days. Data were analyzed using mixed models, adjusting for total monitoring time. Results Girls engaged in 25.0 ± 0.9 minutes/day of MVPA. Dance classes contributed 28.7% (95% CI: 25.9%-31.6% to girls' total MVPA. Girls accumulated more MVPA on program (28.7 ± 1.4 minutes/day than non-program days (16.4 ± 1.5 minutes/day (p Conclusions Dance classes contributed a substantial proportion (29% to girls' total MVPA, and girls accumulated 70% more MVPA and 8% less sedentary behavior on program days than on non-program days. Dance classes can make an important contribution to girls' total physical activity.

Solar building study. Final report. Spinney Gardens [Crystal Palace, London

Energy Technology Data Exchange (ETDEWEB)

Vaughan, N; Alexander, D; Jenkins, H; Jones, P; Drayton, R

1991-10-01

The performance of a two-storey terraced house with passive solar heating features is described. Total annual fuel use of 10896 kWh compared very favourably with that of a well insulated double glazed design. Fuel used for space heating was 80 kWh/m{sup 2}/year. The energy performance was substantially influenced by solar gains. Without such gains gas use for space heating would have been 30% higher. The solar performance was not at the expense of occupant comfort, for there was little reported overheating, due to the adequate isolation of the conservatory from the living areas. Although very comfortable the building was most valued for its character, which was strongly influenced, both indoors and out, by the conservatory. At Pound 518/m{sup 2} GFA (71m{sup 2}) (2nd 1/4 1989) Spinney Gardens, with a conservatory, was estimated to cost more than comparable traditional house Pound 506/m{sup 2} GFA (64m{sup 2}) without a conservatory.

Waldo Bustamante

2014-05-01

Full Text Available Overheating, glare, and high-energy demand are recurrent problems in office buildings in Santiago, Chile (33°27'S; 70°42'W during cooling periods. Santiago climate is warm and dry, with high solar radiation and temperature during most of the year. The objective of this paper is to evaluate the thermal and daylighting performance of office buildings transparent façades composed of three different complex fenestration systems (CFS. Each CFS contains a different external shading device (ESD: (1 external roller, (2 vertical undulated and perforated screens, and (3 tilted undulated and perforated screens. The study was carried out by in situ monitoring in three office buildings in Santiago, Chile. Buildings were selected from a database of 103 buildings, representing those constructed between 2005 and 2011 in the city. The monitoring consisted of measuring the short wave solar and daylighting transmission through fenestration systemsby means of pyranometers and luxometers, respectively. This paper shows measurements that were carried out during summer period. A good performance is observed in a building with the external roller system. This system—applied to a northwest façade—shows a regular and high solar and daylighting control of incoming solar radiation. The other two ESD systems evidence a general good performance. However, some deficiencies at certain times of the day were detected, suggesting a non-appropriated design.

Enache Lorette

2017-03-01

Full Text Available The substance of the spiritual and cultural life is the syncretism of the arts from the performer-spectator division, that was made concurrently with the “dance” segmentation into work and pleasure. Words were held in formulas, gestures and dance in rhythm. Today, dance is mostly seen as the art of gesture. However, it is remarkable to reflect at to what extent the dance, as an organic necessity, it could further develop into hermetic structures that would still require analyses and studies from researchers in the field. In today‟s theatrical landscape, this formula of artistic expression which was called theatre dance evolved so much so that gesticulations and body exploration became its core components.

Efficient energy use and solar building construction; Rationelle Energieverwendung und Solares Bauen

Energy Technology Data Exchange (ETDEWEB)

Ebert, H.P. [Bayerisches Zentrum fuer Angewandte Energieforschung e.V., Wuerzburg (Germany)

2007-06-15

Houses for the 21st century must be optimised in terms of energy saving and, particularly in our latitudes, thermal insulation in the winter. These requirements can be met using innovative heat insulation systems and heat storage components. Recent developments for opaque insulation include super-insulating vacuum insulation panels, while for transparent applications there is ongoing development work on vacuum glazing. Ensuring a high solar input during the cold season and efficient protection against overheating in the warm season falls within the scope of architectural design. It can be facilitated by the use of building components made of micro or macro-integrated latent heat storage materials.

A norming study and library of 203 dance movements.

Science.gov (United States)

Christensen, Julia F; Nadal, Marcos; Cela-Conde, Camilo José

2014-01-01

Dance stimuli have been used in experimental studies of (i) how movement is processed in the brain; (ii) how affect is perceived from bodily movement; and (iii) how dance can be a source of aesthetic experience. However, stimulus materials across--and even within--these three domains of research have varied considerably. Thus, integrative conclusions remain elusive. Moreover, concerns have been raised that the movements selected for such stimuli are qualitatively too different from the actual art form dance, potentially introducing noise in the data. We propose a library of dance stimuli which responds to the stimuli requirements and design criteria of these three areas of research, while at the same time respecting a dance art-historical perspective, offering greater ecological validity as compared with previous dance stimulus sets. The stimuli are 5-6 s long video clips, selected from genuine ballet performances. Following a number of coding experiments, the resulting stimulus library comprises 203 ballet dance stimuli coded in (i) 25 qualitative and quantitative movement variables; (ii) affective valence and arousal; and (iii) the aesthetic qualities beauty, liking, and interest. An Excel spreadsheet with these data points accompanies this manuscript, and the stimuli can be obtained from the authors upon request.

Managing of the sun in the architecture; Manejo del sol en la arquitectura

Energy Technology Data Exchange (ETDEWEB)

Gomez Azpeitia, Luis Gabriel [Facultad de Arquitectura y Diseno, Universidad de Colima (Mexico)

2005-07-01

The solar energy is the source responsible for most of the climatic processes that occur in the planet. From its magnitude, but mainly from its angle of incidence on the atmosphere and on the surface of the oceans and the Earth, depend the daily and seasonal fluctuations of temperature, and therefore the changes in the atmosphere's humidity content as well as pressure differentials that in their turn generate wind currents as well. The architecture, as an integral part of the earth surface, is interrelated with the sun since the relative position of the sun in respect to the buildings is fundamental to obtain energy efficiency as well as comfort in the inhabitants and adjustment to the surroundings. Hence the requirement that the architects formulate their projects in agreement to the sun path, to the different seasons of the year, either to avoid their radiation or to take advantage of it. In this presentation, it is intended to make a fast review of all the tools of support so that the architects recommend the practical use of some of them and so to demonstrate with a practical example the utility that they have in the process of architectural design. [Spanish] La energia solar es la fuente responsable de la mayor parte de los procesos climaticos que ocurren en el planeta. De su magnitud, pero sobre todo de su angulo de incidencia sobre la atmosfera y sobre la superficie de los oceanos y de la tierra, dependen las fluctuaciones de temperaturas diarias y estacionales, y por lo tanto cambios en el contenido de humedad de la atmosfera asi como diferencias de presion que a su vez generan las corrientes de viento. La arquitectura, como parte integral de la superficie terrestre esta interrelacionada con el sol, ya que la posicion relativa del sol con respecto a los edificios es fundamental para lograr eficiencia energetica, confort en los habitantes y adecuacion al entorno. De ahi la exigencia de que los arquitectos formulen sus proyectos en concordancia a la

The Dancing Manias: Psychogenic Illness as a Social Phenomenon.

Science.gov (United States)

Lanska, Douglas J

2018-01-01

The dancing mania erupted in the 14th century in the wake of the Black Death, and recurred for centuries in central Europe - particularly Germany, the Netherlands, and Belgium - finally abating in the early 17th century. The term "dancing mania" was derived from "choreomania," a concatenation of choros (dance) and mania (madness). A variant, tarantism, was prevalent in southern Italy from the 15th to the 17th centuries, and was attributed at the time to bites from the tarantula spider. Affected individuals participated in continuous, prolonged, erratic, often frenzied and sometimes erotic, dancing. In the 14th century, the dancing mania was linked to a corruption of the festival of St. John's Day by ancient pagan customs, but by the 16th century it was commonly considered an ordeal sent by a saint, or a punishment from God for people's sins. Consequently, during outbreaks in the 14th and 15th centuries, the dancing mania was considered an issue for magistrates and priests, not physicians, even though the disorder proved intractable to decrees and exorcisms. However, in the 16th century Paracelsus discounted the idea that the saints caused or interceded in the cure of the dancing mania; he instead suggested a psychogenic or malingered etiology, and this reformulation brought the dancing mania within the purview of physicians. Paracelsus advocated various mystical, psychological, and pharmacological approaches, depending on the presumptive etiologic factors with individual patients. Only music provided any relief for tarantism. Later authors suggested that the dancing mania was a mass stress-induced psychosis, a mass psychogenic illness, a culturally determined form of ritualized behavior, a manifestation of religious ecstasy, or even the result of food poisoning caused by the toxic and psychoactive chemical products of ergot fungi. In reality, dancing manias did not have a single cause, but component causes likely included psychogenic illness, malingering, and

This Solar Design Workbook presents solar building design applications for commercial buildir^s. The book is divided into four sections. The first section describes the variety of solar applications in buildings including conservation aspects, solar fundamentals, passive systems, active systems, daylighting, and other solar options. Solar system design evaluation techniques including considerations for building energy requirements, passive systems, active systems, and economics are presented in Section II. The third section attempts to assist the designer in the building design process for energy conservation and solar applications including options and considerations for pre-design, design, and post-design phases. The information required for the solar design proee^ has not been fully developed at this time. Therefore, Section III is incomplete, but an overview of the considerations with some of the design proces elements is presented. Section IV illustrates ease studies that utilize solar applications in the building design.

Demers, Marika; Thomas, Aliki; Wittich, Walter; McKinley, Patricia

2015-01-01

To identify clinicians' perceptions regarding the facilitators and barriers to the use of dance in rehabilitation. This study used a qualitative descriptive design. Three focus groups were conducted with clinicians across three purposively selected rehabilitation centers. Data were analyzed using thematic content analysis. Fourteen allied health-care professionals (six occupational therapists, six physical therapists, and two social workers) with previous dance experience participated in this study. Four main themes emerged from the analysis representing the personal and organizational factors influencing on the implementation of dance interventions: (1) Clinician's dance experience and training, (2) Interest and personal beliefs towards using dance as a potential intervention, (3) Support from the organization of the institution, and (4) Available resources. Although each site was different, the main factors acting as barriers and facilitators were similar for all three sites. The identification of the barriers and facilitators to implementing dance in rehabilitation is the first step to support the translation of knowledge about dance. A tailored approach designed for clinicians and managers should address the main barriers to knowledge use about dance, as a potential rehabilitation modality for individuals with disabilities. Personal and organizational factors can act simultaneously as barriers and facilitators to the implementation of a dance intervention. Lack of time for professional development and lack of support from the organization are the main barriers to the uptake of knowledge about dance in rehabilitation. A knowledge translation strategy addressing the barriers to knowledge use is helpful for clinicians and managers facilitating the implementation of dance in rehabilitation settings.

This paper describes building energy system production and usage monitoring using examples from the new RETScreen Performance Analysis Module, called RETScreen Plus. The module uses daily meteorological (i.e., temperature, humidity, wind and solar, etc.) over a period of time to derive a building system function that is used to monitor building performance. The new module can also be used to target building systems with enhanced technologies. If daily ambient meteorological and solar information are not available, these are obtained over the internet from NASA's near-term data products that provide global meteorological and solar information within 3-6 days of real-time. The accuracy of the NASA data are shown to be excellent for this purpose enabling RETScreen Plus to easily detect changes in the system function and efficiency. This is shown by several examples, one of which is a new building at the NASA Langley Research Center that uses solar panels to provide electrical energy for building energy and excess energy for other uses. The system shows steady performance within the uncertainties of the input data. The other example involves assessing the reduction in energy usage by an apartment building in Sweden before and after an energy efficiency upgrade. In this case, savings up to 16% are shown.

Aktas, Gurbuz; Ogce, Filiz

2005-01-01

Even though the field of medicine has developed tremendously, the wide variety of cancer is still among chronic and life threatening disease today. Therefore, the specialists constantly research and try every possible way to find cure or preventive ways to stop its further development. For this reason, studies concerning the chronic disease such as cancer have been spread to many different fields. In this regard, many other alternative ways besides medicine, are used in prevention of cancer. Nutritional therapy, herbal therapy, sportive activities, art therapy, music therapy, dance therapy, imagery, yoga and acupuncture can be given as examples. Among these, dance/movement therapy which deals with individuals physical, emotional, cognitive as well as social integration is widely used as a popular form of physical activity. The physical benefits of dance therapy as exercise are well documented. Studies have shown that physical activity is known to increase special neurotransmitter substances in the brain (endorphins), which create a state of well-being. And total body movement such as dance enhances the functions of other body systems, such as circulatory, respiratory, skeletal, and muscular systems. Regarding its unique connection to the field of medicine, many researches have been undertaken on the effects of dance/movement therapy in special settings with physical problems such as amputations, traumatic brain injury, and stroke, chronic illnesses such as anorexia, bulimia, cancer, Alzheimer's disease, cystic fibrosis, heart disease, diabetes, asthma, AIDS, and arthritis. Today dance/movement therapy is a well recognized form of complementary therapy used in hospitals as well as at the comprehensive clinical cancer centres.

In a spin: the mysterious dancing epidemic of 1518.

Science.gov (United States)

Waller, John C

2008-09-01

In 1518, one of the strangest epidemics in recorded history struck the city of Strasbourg. Hundreds of people were seized by an irresistible urge to dance, hop and leap into the air. In houses, halls and public spaces, as fear paralyzed the city and the members of the elite despaired, the dancing continued with mindless intensity. Seldom pausing to eat, drink or rest, many of them danced for days or even weeks. And before long, the chronicles agree, dozens were dying from exhaustion. What was it that could have impelled as many as 400 people to dance, in some cases to death?
