Abstract:
Universally practiced across the disciplines, description is also consistently devalued or overlooked. In this introduction to the special issue “Description Across Disciplines,” Sharon Marcus, Heather Love, and Stephen Best propose that description is a critical practice more complex (and less contradictory) than its detractors have taken it to be. They argue that turning critical attention toward description’s nuances gives us access to the ways that scholars conventionally assign and withhold value and prestige. The authors set forth a number of principles (using their contributors’ essays as a guide) toward the end of “building a better description.”

Abstract:
In this article, Anthony Bryk, Heather Harding, and Sharon Greenberg report on a roundtable jointly sponsored by Teach For America and the Carnegie Foundation for the Advancement of Teaching. The authors brought together a group of scholars and practitioners with a broad range of perspectives and asked them to explore several questions related to the emerging national narrative on effective teachers: What is an effective teacher? How do we leverage this moment of enormous energy in producing more effective teaching to advance meaningful improvements at scale? Where are the current sites of success? What can we learn from what is working? The article is organized around the edited transcript of the roundtable discussion and is supplemented by author commentaries. The authors seek to illuminate and reimagine the current “nonsystem” in order to accelerate progress toward a wholly new approach to developing the teaching force our nation and our children need.

Abstract:
Human organism is exposed to harmful action of free radicals which are produced as well endogenically as egzogenically. The oxidation activity of free radicals can lead to the conversion of systemic biomolecules. As a consequence, there is a threat of, many severe diseases. Antioxidative agents which occur in natural products (also in honey) raise a possibility of protection against the harmful action of above mentioned radicals. Polyphenolic compounds - flavonoids, phenolic acids and ascorbic acid - are the most important antioxidative agents. The research of many authors proves that honey, given orally, shows an antioxidative activity. The level of antioxidative agents in serum after the consumption of honey is high and surpasses the antioxidative activity of tea. Dark honeys (honeydew and heather) have considerably higher antioxidative activity in comparison to light ones (acacia, lime, polyfloral).

Abstract:
Studying the socio-ecological systems which produce food highlights the entangled nature of humans, other species and ecosystems near and far. The three texts discussed in this essay have this awareness in the foreground. Participants in the solidarity economy and artisan cheesemakers know this, and the three authors do as well, demonstrating an integration of ecological awareness in their research and the pursuit of new knowledge. Cristina Grasseni, Heather Paxson and Anna Tsing trace connections and describe flows of organisms, food, skills and ideas, from the microbial community on the surface of a maturing cheese to global trade networks shaping mushrooms, mushroom pickers and forests. Each demonstrates the tight synergies of human culture and more-than-human nature that shape ecosystems and produce food beyond increasingly fragile capitalist industrial food production systems.

Full text
Abstract:
Abstract In spite of the rainbow flag’s importance as a symbol for transnational queer belonging and its meanings for the survival of queers all over the world, much critical queer Anglo-Saxon research and activism concerning the rainbow flag and the celebration of Pride claims that it has lost its radical potential through processes of normalisation, mainstreaming, homonationalism and commercialisation. In order to address other queer political issues, alternative Pride events are organized in parallel with conventional Pride celebrations. This chapter will discuss two Pride events held in Gothenburg, Sweden, in 2019, Reclaim Pride and Öckerö Pride, drawing on auto-ethnographic methods. It will reflect on two connected questions: What meanings, emotions, actions and temporalities are (re)produced as a result of the relationship between the events, the rainbow flag, the concept of Pride and the activists/participants—including the author? In what ways do the rainbow flag and the concept of Pride work as co-producers of belongings as well as disbelongings—and how does the author’s position as a Swedish, middle-class, white, lesbian, feminist, mother, former activist and now sociologist affect her feelings of belonging and disbelonging? It is shown that the rainbow flag is a very topical and heated cultural artefact in the Swedish political arena, in which racism, homophobia and Islamophobia are growing. The author’s experiences and emotions at the two Pride events reflect the ambivalent struggle that takes place at the borders of belonging and disbelonging. Temporality and space are important aspects of the contextualisation that needs to be applied in order to grasp the different effects that processes of inclusion and exclusion have on queer people in different places and situations.

Abstract:
Education for sustainable development (ESD) initially emerged around the 1990s, and it has opened the possibility to re-think areas such as management education. Although the original purpose of inclusiveness and creativity has been gradually replaced by metrics, while keeping the idea of “development as growth” largely unquestioned, drawing upon the work of organisational researchers like Heather Hopfl, this chapter presents a critique of the evolution of ESD in the UK revealing a rationale that transforms guiding principles into metrics, emphasising “efficiency” over “care.” The researchers relate to the principles of humanistic management, in its consideration of social value generation linked to financial success. The authors propose to enhance the notion of “values” by revisiting the concept of “virtues,” particularly in the consideration of sustainability. Finally, the authors draw upon interest in aesthetics and praxis to propose an “aesthetic education for sustainability,” as a critical and purposeful approach of questioning and imagining hopeful ways of living and learning.

Abstract:
At agricultural facilities, the main attention is paid to the formation and maintenance of their microclimate parameters, and mechanization of storage processes. As world experience shows, it is necessary to develop and implement energy-saving systems and the use of renewable energy sources. The authors have developed energy-saving systems based on the heat pump, with upgraded electrical regulators. The developed system (patent 100873), uses thermoelectric elements and a low-potential energy source, to effectively maintain the temperature parameters of the microclimate during long-term storage of potatoes, but it requires a large amount of electricity consumption (30 to 35 kW), so the authors have developed an energy-saving system based on a heat pump (patent 123909). The temperature regime is achieved by using a thermoelectric cooler-heater and an electric heater. The humidifier allows for maintaining the necessary relative air humidity.

Abstract:
Measuring the performance of solar energy and heat transfer systems requires a lot of time, economic cost, and manpower. Meanwhile, directly predicting their performance is challenging due to the complicated internal structures. Fortunately, a knowledge-based machine learning method can provide a promising prediction and optimization strategy for the performance of energy systems. In this chapter, the authors show how they utilize the machine learning models trained from a large experimental database to perform precise prediction and optimization on a solar water heater (SWH) system. A new energy system optimization strategy based on a high-throughput screening (HTS) process is proposed. This chapter consists of: 1) comparative studies on varieties of machine learning models (artificial neural networks [ANNs], support vector machine [SVM], and extreme learning machine [ELM]) to predict the performances of SWHs; 2) development of an ANN-based software to assist the quick prediction; and 3) introduction of a computational HTS method to design a high-performance SWH system.

Abstract:
In recent years, social media have become an important avenue for self-expression. At the same time, the ease with which individuals disclose their private information has added to an already heated debate about the privacy implications of interactive media. This chapter investigates the relationship between disclosure of personal information in social media and two related trends: the increasing value of subjective or private experience as a social currency and the evolving nature of automated dataveillance. The authors argue that the results of the extended ability of individuals to negotiate their identity through social media are contradictory. The information revealed to communicate the complexity of one’s identity becomes an extensive source of data about individuals, thereby contributing to the functioning of a new regime of surveillance.

In 2016 24th International Conference on Nuclear Engineering. American Society of Mechanical Engineers, 2016. http://dx.doi.org/10.1115/icone24-60560.

Full text
Abstract:
Heat removal through pool boiling is limited by the phenomena of critical heat flux (CHF). CHF enhancement is vitally important in order to satisfy demand for the cooling technology with high heat flux in In Vessel Retention (IVR). Various surface modifications of the boiling surface, e.g., integrated surface structures and coating of a micro-porous have been proven to effectively enhance the CHF in saturated pool boiling. We have been proposed a novel method of attaching a honeycomb structured porous plate on a considerably large heater surface. Previous results, by the authors in [1] reported that CHF has been enhanced experimentally up to more than approximately twice that of a plain surface (approximately 2.0 to 2.5 MW/m2) with a diameter of 30 mm heated surface. However, it is necessary to demonstrate the method together with infinite heater surface within laboratory scale. It is important that cooling techniques for IVR could be applicable to a large heated surface as well as remove high heat flux. Objective of this study is to investigate the CHF of honeycomb porous plate and metal solid structure in nanofluid boiling or water boiling on a large heated surface. Water-based nanofluid offers good wettability and capillarity. While metal solid structure is installed on honeycomb porous plate to increase the number of vapor jet. Experimental results of honeycomb porous plate and combination of honeycomb porous plate and metal solid structure in water-based nanofluid boiling shows that CHF is increased up to twice [2] and thrice, respectively compared to plain surface in water boiling. To the best of the author’s knowledge, the highest value (3.1 MW/m2) was obtained for a large heated surface having a diameter of 50 mm which is regarded as infinite heated surface. This demonstrates potential for general applicability to have more safety margin in IVR method.

Abstract:
The temperature dependency of surface tension of aqueous solutions of some alcohol such as butanol and pentanol behaves in a nonlinear manner. Namely, the value of surface tension increases from some temperature when the solution is heated. Since this was discovered about 30 years ago, several experimental studies were done about the liquid motion focusing on the difference from the normal fluids. At the same time several ideas have been attempted in the application to heat pipes and so on to promote the heat transfer. The direction of thermocapillary force in liquid film of the nonlinear solution on a heated surface acts in the same direction to solute Marangoni force. This characteristic will be much marked in small scale systems such as mini/micro channels. In this talk the author surveys the research about the special aqueous solutions and their applications until now. Moreover, the author will report the new measurement results about the nonlinearity of the temperature dependency of the surface tension of the solutions. Also the author will present the result of flow boiling and the liquid motion when the nonlinear aqueous solution was used as test fluid for mini channel of 1 mm ID. The mini/micro channel was a single quartz tube with thin film heater coated on its outer surface. When the channel was mini channel of 1 mm ID, the dryout position was not much different from the case when pure water was used as test fluid. But the liquid motion was much different. The experiments when the channel was smaller micro channel (for example, 500 μm ID), are being done in the authors’ laboratory. Moreover, the author is also doing the experiments about the boiling heat transfer in regard to the increase of CHF when the nonlinear solution was used as test fluid.

Full text
Abstract:
Forced convection transient heat transfer coefficients were measured for helium gas and carbon dioxide gas flowing over a twisted heater due to exponentially increasing heat input (Q0exp(t/τ)). The twisted platinum plate with a thickness of 0.1 mm was used as test heater and heated by electric current. The heat generation rate was exponentially increased with a function of Q0exp(t/τ). The gas flow velocities ranged from 1 to 10 m/s, the gas temperatures ranged from 313 to 353 K, and the periods of heat generation rate ranged from 46 ms to 17 s. The surface temperature difference and heat flux increase exponentially as the heat generation rate increases with the exponential function. Transient heat transfer coefficients increase with increasing gas flow velocity. The geometric effect of twisted heater in this study shows an enhancement on the heat transfer coefficient. Empirical correlation for quasi-steady-state heat transfer was obtained based on the experimental data. The data for heat transfer coefficient were compared with those reported in authors’ previous paper.

Full text
Abstract:
A new a dual-service dehumidifier water heater (WHD) appliance is being researched and developed by the authors. Prior research on a similar appliance, a heat pump water heater (HPWH), has demonstrated the unit’s increased performance and energy saving, and through collaboration, significant progress has been made toward developing the WHD into a potentially marketable product. The primary energy use in residential households is space conditioning (49%), and the second major energy use is hot water consumption. In DOE’s 2004 Buildings Data Book, 15.5 percent of residential energy utilization is consumed by water heating (DOE 2004, Table 1.2.3). The two major types of residential water heaters are direct gas fired (~55%) and electric resistance (~45%) (DOE 2004, Appliance Magazine 2005). The maximum efficiency of a standard electric resistance water heater is 1 (100%), and progress has been made to increase the efficiency of the current standard heaters to approximately 95 percent (DOE 2004, Table 5.10.6), which is roughly the maximum available with today’s technology. However, if the standard system is replaced by a Heat Pump Water Heater (HPWH), the performance can be increased by 140 percent (Zogg and Murphy 2004). The WHD operates as a HPWH while heating water and as a dedicated dehumidifier when water heating is not necessary. This paper presents the general design and laboratory testing results of a WHD. Preliminary performance data reveal coefficient of performances (COP) of approximately 2.2 during water heating. Further, market analysis has revealed that a potential need for this new technology is in regions with high humidity (Ashdown et al. 2004). These regions are primarily in the Northeast, Southeast and some coastal areas of the U.S. Current HPWH units do not have dedicated dehumidification and have a very small share of the residential water heat market. Of the 9.55 million residential water heaters sold in 2003 only about 2,000 of them were HPWHs (DOE 2004, Table 5.10.15).

Abstract:
Slider with thermal fly height control (TFC) uses a thermal heater to produce localized thermal protrusion and adjust the vertical position of the read/write head. This paper reports authors’ efforts in exploring large protrusion stroke with minimal heater power input whilst preserving heater robustness in the TFC slider, with an optimized thermal nano-actuator design. Effects of both heater line width and line spacing on TFC slider performances are investigated. A novel ‘Stream-River’ heater design approach is proposed. Simulation results conclude that the “Stream-River” approach is of both high power-protrusion efficiency and high heater robustness.

Abstract:
“Energy saving” and “environment protection” have been becoming key issues in the field of energy. A thermal power unit has a regenerative process, regardless the unit is reheating or non-reheating system, when the feedwater temperature and the stages of the regenerative cycle keep constant, there must have an optimum enthalpy rise assignment of the heater, which the turbine efficiency is the highest [1,3] .The optimum feedwater temperature is based on the optimum enthalpy assignment. However, at present, there is no better method to solve this problem. This paper presents a simple and effective method for the achievement of enthalpy rise of the heater. Industries can use this technology as a guide to achieve the enthalpy rise of the heater and improve the turbine efficiency and save the energy. The method is based on the theory of equivalent condensing steam loss investigated by the authors.

Abstract:
A literature review carried out by the authors reveals that that a CFD analysis has not been the focus of attention to evaluate the efficacy of turbulators for improving the thermal performance of solar air heaters. A three dimensional CFD analysis is carried out in the present work to augment the performance of solar air heater. Arc shaped wire turbulators (with forward and reverse curvature aligned with flow direction), V-shaped wire turbulators (with forward and reverse geometry with respect to the flow direction) and Straight turbulators are used in this study to improve the flow turbulence and thereby enhance the convective heat transfer to air. The numerical results are validated with experimental results for model without turbulator to calibrate the numerical methodology. The numerical results show that turbulators whether curved or straight are useful in enhancing the heat transfer rates. The Arc shaped turbulators have been found to provide better heat transfer coefficient value compared to that of straight and V-shape turbulators. Also interestingly, Reverse arc turbulators seems to provide better heat transfer coefficient value compared to forward arc turbulators. Further, V-angle has no significant effect for both forward and reverse V-turbulator configurations.

Abstract:
The authors have developed test beds heated green roofs in New York City and geothermal heated gardens in Iceland using waste heat. A thermoelectric generator developed by the authors for these gardens currently provides more than 6 watts of steady state power. This sustainable power source is independent from the grid and is used for web cameras. The test beds need a mobile, web-accessible robot platform for additional monitoring that is battery-charged by the thermoelectric generator. This robot’s power consumption must match the constraints of the thermoelectric generator’s output. This paper presents the design and construction of a low-power walking quadruped robotic platform with a specifically designed walking algorithm. The robot will eventually provide the needed web accessible remote monitoring and maintenance capabilities for the test beds. Remote supervision and control of multiple heated green roofs and heated gardens will be possible from a central location.

Abstract:
Modeling and unit-cost optimization of a water-heated humidification-dehumidification (HDH) desalination system were presented in previous work of the authors. The system controlled the saline water flow rate to prevent salts from precipitating at higher water temperatures. It was then realized that this scheme had a negative impact on condensation performance when the controlled flow rate was not sufficiently high. This work builds on the previous system by disconnecting the condenser from the saline water cycle and by introducing a solar air heater to further augment the humidification performance. In addition, improved models for the condenser and the humidifier were used to obtain more accurate productivity estimations. The Heuristic Gradient Projection (HGP) optimization procedure was also refactored to result in reduced number of function evaluations to reach the global optimum compared to Genetic Algorithms (GA’s). A case study which assumes a desalination plant on the Red Sea near the city of Hurghada is presented. The unit-cost of produced fresh water for the new optimum system is $0.5/m3 compared to $5.9/m3 for the HDH system from previous work and less than the reported minimum cost of reverse osmoses systems.

Abstract:
The authors develop a small and simple steam-reforming reactor in a home-use size for n-dodecane as a heavy-hydrocarbons fuel. Under the thermal condition controlled by electric heaters and a gas burner with a thermal diffuser, the authors measure the inside-temperature profile and the hydrogen-molecule ratio (concentration) RH2, together with the molecule ratios RCH4, RCO and RCO2 of other main gas components such as CH4, CO and CO2, respectively. Besides, the authors conduct numerical simulations based on a thermal-equilibrium theory, in addition to experiments. As a result, the authors successfully achieve suitable inside-temperature profiles. And, the effects of the liquid-hourly-space velocity LHSV upon RH2, RCH4, RCO and RCO2 are shown, experimentally. For LHSV ≤ 1, the experimental results agree well with the thermal equilibrium theory. This is in consistent with high conversion ratio XC12H26 ≳ 80%. Furthermore, the authors reveal the effects of the temperature T inside the reactor upon the molecule ratios, comparing with the thermal-equilibrium theory.
