Field Performance of Heat Pump Water Heaters in the Northeast

Heat pump water heaters (HPWHs) are finally entering the mainstream residential water heater market. Potential catalysts are increased consumer demand for higher energy efficiency electric water heating and a new Federal water heating standard that effectively mandates use of HPWHs for electric storage water heaters with nominal capacities greater than 55 gallons. When compared to electric resistance water heating, the energy and cost savings potential of HPWHs is tremendous. Converting all electric resistance water heaters to HPWHs could save American consumers 7.8 billion dollars annually ($182 per household) in water heating operating costs and cut annual residential source energy consumption for water heating by 0.70 quads. Steven Winter Associates, Inc. embarked on one of the first in situ studies of these newly released HPWH products through a partnership with two sponsoring electric utility companies, National Grid and NSTAR, and one sponsoring energy efficiency service program administrator, Cape Light Compact. Recent laboratory studies have measured performance of HPWHs under various operating conditions, but publically available field studies have not been as available. This evaluation attempts to provide publicly available field data on new HPWHs by monitoring the performance of three recently released products (General Electric GeoSpring(TM), A.O. Smith Voltex(R), and Stiebelmore » Eltron Accelera(R) 300). Fourteen HPWHs were installed in Massachusetts and Rhode Island and monitored for over a year. Of the 14 units, ten were General Electric models (50 gallon units), two were Stiebel Eltron models (80 gallon units), and two were A.O. Smith models (one 60-gallon and one 80-gallon unit). « less
Diagnosing subsynchronous vibrations in turbomachinery - stable or unstable

Diagnosing Subsynchronous Vibrations in Turbomachinery – Stable or Unstable. (August 2007) Vinayaka Narayanan Rajagopalan, B.E. , R.V College of Engineering, India Chair of Advisory Committee: Dr. John M.Vance Rotordynamic instability, commonly observed as subsynchronous vibration, is a serious problem that can cause heavy damage to a turbomachine or make it incapable of operation because of high vibration levels. All subsynchronous vibrations, howver, are not necessarily unstable. If the amplitude of the subsynchronous vibration is large, it can cause damage to seals, bearings, or process wheels. If it is small, the question arises as to whether it has the potential to grow larger (“instability”) or whether it is benign and harmless. A way to know would be helpful. The objective of this study is to signal analyze subsynchronous vibrations in turbomachinery and distinguish benign subsynchronous vibration from the true potential instabilities. Effort is also made to identify unique signatures to a cause to aid in faster diagnosis. First, a computer simulation study is conducted on four rotors, including two gasreinjection compressors that went unstable, to examine the possibility of using the change in the synchronous phase angle as a possible indicator of impending instability. Results indicate that, phase angle can be used as an indicator of potential instability, provided that a judicious approach is used, as the synchronous phase angle, by itself,

Measurement and simulation of two-phase CO2 cooling in Micromegas modules for a Large Prototype of Time Projection Chamber

The readout electronics of a Micromegas (MM) module consume nearly 26 W of electric power, which causes the temperature of electronic board to increase upto 70 ̂C. Increase in temperature results in damage of electronics. Development of temperature gradient in the Time Projection Chamber (TPC) may affect precise measurement as well. Two-phase CO2 cooling has been applied to remove heat from the MM modules during two test beam experiments at DESY, Hamburg. Following the experimental procedure, a comprehensive study of the cooling technique has been accomplished for a single MM module by means of numerical simulation. This paper is focused to discuss the application of two-phase CO2 cooling to keep the temperature below 30 ̂C and stabilized within 0.2 ̂C.
A Potential Valorization Strategy of Wine Industry by-Products and Their Application in Cosmetics—Case Study: Grape Pomace and Grapeseed

Grape pomace and grapeseed are agro-industrial by-products, whose inadequate treatment generates socioeconomic and environmental concerns. Nevertheless, it is possible to valorize them by extracting their bioactive compounds, such as antioxidants (phenolic compounds), vitamin E and fatty acids. The bioactive compounds were extracted using solid-liquid extraction. The yields for phenolic compounds were 18.4 ± 0.4% for grape pomace, and 17.4 ± 0.4%, for grapeseed. For the oil, the yields were 13.3 ± 0.2% and 14.5 ± 0.3% for grape pomace and grapeseed. Antioxidant capacity was assessed by the assay with 2,2-diphenyl-1-picrylhydrazyl (DPPH), and showed that phenolic extract has higher antioxidant capacity than the oils. Grape pomace and grapeseed extracts exhibit, correspondingly, values of 90.8 ± 0.8 and 87.5 ± 0.5 of DPPH inhibition and IC50 of 48.9 ± 0.5 and 55.9 ± 0.7 μgextract·mLDPPH−1. The antimicrobial capacity was assessed by the disk diffusion test, and revealed that, phenolic extracts inhibit the growth of Staphylococcus aureus and Staphylococcus epidermidis. The obtained extracts were incorporated in 10 face cream formulations, with slight modifications in quantities of formulation stabilizers. Their stability was studied for 35 days, and this revealed the possibility of incorporating extracts and oils obtained from by-products as antioxidants in cosmetics, and replacing synthetic ones. As a future recommendation, microencapsulation of the extracts should be performed, in order to increase their stability.
Cloning and expression analysis of the HSL gene in Whitmania pigra (Annelida: Hirudinea)

ABSTRACT Hormone-sensitive lipase (HSL) is the rate-limiting enzyme of lipolysis, which has a certain effect on the reproductive development of parthenogens. To study the effect of HSL on gonad development in Whitmania pigra, a synchronous hermaphrodite, the Whitmania pigra HSL gene was cloned. The cloned Wpi-hsl has a total length of 2492 bp, and the ORF encodes a protein of 787 aa. It is predicted that the Wpi-HSL protein has 98 phosphorylation modification sites on serine, threonine and tyrosine residues. Domain prediction and multiple sequence comparison revealed that Wpi-HSL contains 3 HSL conserved domains, which are closely related to Helobdella robusta, and the amino acid sequence similarity and sequence identity are 49% and 39%, respectively. Fluorescence quantitative PCR results showed that in the mature period, the expression of Wpi-hsl in the male gonads was significantly higher than that in the female gonads. Wpi-hsl may play an important role in the development of W. pigra, especially the development of male gonads. The results of our study provide references for not only further research on leech gonadal development but also the study of reproductive development mechanisms.
Investigating differential teacher effectiveness: searching for the impact of classroom context factors

ABSTRACT This study investigates differential effectiveness of teacher behaviour in relation to classroom composition by searching for the extent to which teachers exhibit the same teaching skills when they teach mathematics in different classrooms within a school year. Twenty-six teachers who taught mathematics in more than one classroom of the same age group of students participated in this study. Quality of teaching was measured through external observations and student questionnaires. Student achievement in mathematics at the beginning and at the end of the school year was measured. Data about each teacher factor of the dynamic model but orientation and dealing with student misbehaviour were generalizable at the teacher level. Multilevel structural equation modelling analysis revealed that all teacher factors had an effect on student achievement. Prior achievement (aggregated at classroom level) had an effect on the functioning of two factors (orientation and dealing with misbehaviour). Implications of findings are drawn.
Millennials’ Self-Identity and Intention to Purchase Sustainable Products

With the rising challenges related to social, economic, and climatic factors, the focus toward adoption of sustainable products is rising. Increasing focus on sustainable products, has influenced the consumer shopping behavior toward greener products. The consumers’ participation showntoward sustainable products is what defines their behavior toward its purchase. Understanding of sustainable consumption in emerging markets is still unexplored which calls for further research. A structured questionnaire was used to collect data from the millennials who belong to the working population of India and have awareness regarding sustainable products and its impact on the environment. The results show that there is a direct relationship between environment self-identity (ESI) and the intention to purchase a sustainable product (PI). Psychological ownership (PO) also plays a role of a partial mediator for the relationship between SI and PI. Environment Concern (EC) and social influence (Soc) are critical factors; their relationship also matters to comprehend the results concretely
Constitutive Model for Timber Fracture under Tensile and Shear Loads

A 2D homogeneous orthotropic constitutive model of tensile and shear fracture in timber based on fixed smeared crack approach has been developed and implemented in ATENA® finite element software. The model captures (1) elastic and inelastic behavior in small deformations range, (2) material orthotropy, both in linear and non-linear range, (3) cracking across or along fibers, and (4) behavior under unloading/reloading. In this contribution we present model validation through numerical simulations of compact tension shear (CTS) tests of Radiata Pine timber.
What Experts Tell about Integrated Marketing Communication for Effective Business Promotion and Sale Strategy

The expert’s study about integrated marketing communications for promotion and sales strategies ineffective business activities is the main objective of this study. We address the core gap here through a literature review that addresses integrated marketing communications in sales and promotions in every business. We found data from more than 50 articles on the economics of marketing and business communications in sales and promotion. After we found the data, we studied it comprehensively under the phenomenological approach to finding findings or answers that were valid and believed to be valid. Because this study was carried out during the implementation of public mobility restrictions, we tried secondary data with a search system with the help of Google Scholar on several scientific publications such as Google book, Taylor, Sagepub, and Elsevier. Based on the existing data and discussion of the results, we conclude that a successful integrated marketing communication will establish a core message, emphasize the competitive advantage, address the right target market, and adapt the message to suit supporting media channels. The message is essentially the same across platforms, but the delivery mechanism varies.
Dental Patients’ Perspective on COVID-19: A Systematic Review

The COVID-19 epidemic has changed patients’ approach to dental treatments. While dentists worldwide have shown an excellent level of adaptability to face the new challenges presented by the unprecedented situation due to the rapid spread of COVID-19, dental patients have witnessed a sudden suspension of elective treatments and a slow resumption of dental care activities after several national lockdowns. In addition, the general climate of anxiety and fear due to the high COVID-19 risk and the high level of mortality has influenced the perception and attitudes of people towards dental activity, inducing many dental patients to avoid appointments to the dentist if not highly urgent. We present an overview of the current state of knowledge about dental patients’ perception, perspective, attitude, and expectations towards a full resumption of regular dental treatments.
Assessing the Impact of Aviation Noise on Housing Prices Using New Estimated Noise Value: The Case of Taiwan Taoyuan International Airport

Aviation noise at airports has a significant impact on nearby residents’ quality of life and residential property values. This study evaluated the impact of aviation noise based on house prices by using three different hedonic price models. Two novel independent noise variables, the estimated aviation noise value and noise reward fund are proposed for constructing effective hedonic price models. The real data of real estate transactions from the region defined by the Taoyuan International Airport’s 60–64 dB day-night average sound level (Ldn) and >=65 dB Ldn noise contours are adopted as empirical data. Empirical results showed that the double-log hedonic price model with the proposed estimated aviation noise variables is the most suitable model for this study. Based on the double-log model, this study found that aviation noise has a significant negative impact on house prices in both noise contour areas of 60–64 dB Ldn and >=65 dB Ldn. The rate of decline in house prices is approximately USD 2356.02/dB and USD 3622.78/dB in the 60–64 dB Ldn and >=65 dB Ldn contour areas, respectively. Our results also showed that the noise reward fund had no significant impact on the house prices which implies that the current subsidy method has been maintained at an appropriate level for Taoyuan International Airport.

Rainwater tanks and microbial water quality: Are the indications clear?

Abstract Deriving maximum economic and water savings benefits from rainwater harvesting in the urban environment requires the use of rainwater for internal applications, including showering/bathing, laundry and toilet flushing. Widespread use of rainwater for these applications has been hindered by uncertainty over quality and perceptions of health risk. This study examined the presence and abundance of the faecal indicators E. coli, enterococci and total coliform in over 100 water samples collected from rainwater tanks in eastern Australia. A large proportion of samples were compliant with the requirements of mains water drinking standards, especially among those collected via a hot water system, while almost universal compliance with bathing water quality standards was observed. Indicator species were found to represent a very small proportion of total bacterial contamination and no significant correlation between faecal indicator counts and heterotrophic plate counts was observed. Furthermore, enterococci were not significantly correlated with the other indicator groups. On average, heterotrophic counts were found to be dominated by Pseudomonas spp and several other widely distributed environmental organisms. The implications of these findings with regard to the scope of domestic rainwater use in the urban environment, and the difficulty in achieving reliable risk assessment, have been discussed.
Organic methods to control root rot of peas and spinach in north-central West Virginia

Organic methods to control root rot disease of peas and spinach in north central West Virginia Hannah Witten Schrum Root rot disease is a limiting factor in organic production of cool season crops for many growers in North central West Virginia. In attempt to control root rot and its devastating impact on crop stands we decided to study a number of environmental, cultural, and biological control methods. The purpose of this work was to study the effect of alterations of the seed environment on disease incidence (measured by crop emergence and survival 21 days after planting) and thereby define techniques which are suitable for small growers to adopt if they have root rot problems. We therefore explored four broadly defined methods of controlling the disease: the relationship between the amount of soil organic matter (OM) and disease incidence; the efficacy of soil pasteurization via solarization; the suppressive effects of cover crops on disease incidence; cultivation techniques and the influence of those techniques on the physical properties of the rhizosphere and disease incidence. Neither high nor low fertility treatments had an impact on crop emergence. In addition, regression analysis indicated that there was no correlation between the amount of organic matter and emergence of either peas or spinach. Results from solarization field experiments showed a strong (P<0.05) positive effect of solarization on the emergence of peas and spinach. Experiments with cover crops/ green manures clearly illustrated that common cover crops such as buckwheat or fieldpea serve no purpose in suppressing root rot pathogens, at least not in the short term. In that particular experiment, control plots (those left fallow) supported the highest emergence rates for both pea and spinach. In terms of disease control, the method with the best results in controlling root rot was transplanting. In addition this method is more practical, reliable and produces consistent results compared to the variety of other techniques and influences this project investigated.
Metals In Sediments of Sustainable Urban Drainage Structures In Scotland

Sustainable urban drainage solutions increasingly use structures, such as wetlands and ponds, to improve water quality. Previous studies have demonstrated the effectiveness of these structures in removing metals from runoff, but the fate of the captured contaminants has been neglected. Whilst organic contaminants and nutrients may biodegrade and be taken up by plants, metals are expected to accumulate in sediments. EDTA-extractable cadmium, chromium, copper, lead, nickel and zinc were measured in sediment sampled from three urban drainage structures (a wetland and two ponds receiving industrial and residential storm drainage) in Scotland, UK. Metal concentrations showed considerable variability within each structure, probably reflecting short-circuiting of flow. Zinc, chromium and cadmium concentrations were at very low levels at all sites, but copper, nickel and lead exceeded background concentrations for aquatic sediments. An index of metal contamination showed that the metal content of sediments increased with the age of the structure.
Constrained Consensus in Nonlinear Multiagent Systems Under Switching Topologies

Regarding constrained consensus in nonlinear systems, most of the currently available results require fixed communication topologies. We investigate constrained consensus without such requirements for a type of strict-feedback system. To approach the discontinuous nature associated with topology switching and output constraints, we tailor a novel dynamic feedback system based on a transformed function to yield a desired output. This auxiliary dynamics enables us to develop a distributed control strategy for each agent utilizing minimal information from neighboring agents, namely, the neighbors’ output information. It is shown that consensus can be reached without constraint transgressions and that the boundedness of all signals in the closed-loop system is preserved. A simulation study validates the efficacy of the proposed strategy.
What makes people willing to comment on social media posts? The roles of interactivity and perceived contingency in online corporate social responsibility communication

ABSTRACT Interactivity is an important concept in the study of online social processes. Two experiments tested how interactivity influenced people’s willingness to comment on social media and their perceptions of a company’s corporate social responsibility (CSR) efforts. Across two operationalizations of interactivity (presence/absence of replies, high/low degree of reference to earlier messages), interactivity led to greater perceived contingency, which led to greater willingness to comment and more positive CSR perceptions. Results advance the interactivity effects model by demonstrating that (a) perceived contingency plays a crucial role in interactivity effects, (b) language intensity moderates the relationship between perceived contingency and willingness to comment, and (c) perceived contingency is fostered only by companies’ interactive messages and not consumers’ interactive messages.
Is a Plant-Based Diet Associated with Relationship Aggression?

Examinations of links between plant-based diet and indices of physical and mental health have received increased attention in the scientific literature in recent years. However, there has been little to no published research examining associations between plant-based diet and use of aggressive behavior. The current study examined the link between a plant-based diet and partner aggression in a nationally representative United States sample of 1,763 individuals while controlling for childhood trauma and partner aggression victimization. Results indicated that while a plant-based diet was associated with greater use of relationship aggression at the bivariate level, this association did not remain significant when accounting for childhood trauma and aggression victimization. These results suggest the importance of considering the role of trauma and victimization when examining links between plant-based diet and aggression, and point to a number of possible avenues for additional investigation to better understand these associations.
