    The application of biochar (BC) as a filler in polymers can be viewed as a sustainable approach that incorporates pyrolysed waste based value-added material and simultaneously mitigate bio-waste in a smart way. The overarching aim of this work was to investigate the electrical, mechanical, thermal and rheological properties of biocomposite developed by utilizing date palm waste-derived BC for the reinforcing of polypropylene (PP) matrix. Date palm waste derived BC prepared at (700 and 900°C) were blended at different proportions with polypropylene and the resultant composites (BC/PP) were characterized using an array of techniques (scanning electron microscope, energy-dispersive X-ray spectroscopy and Fourier transform infra-red spectroscopy). Additionally the thermal, mechanical, electrical and rheological properties of the BC/PP composites were evaluated at different loading of BC content (from 0 to15% w/w). The mechanical properties of BC/PP composites showed an improvement in the tensile modulus while that of electrical characterization revealed an enhanced electrical conductivity with increased BC loading. Although the BC incorporation into the PP matrix has significantly reduced the total crystallinity of the resulted composites, however; a positive effect on the crystallization temperature (T c ) was observed. The rheological characterization of BC/PP composites revealed that the addition of BC had minimal effect on the storage modulus (G') compared to the neat (PP). Copyright © 2017 Elsevier B.V.

    The electricity system in the United States is a complex mechanism where different technologies, jurisdictions and regulatory designs interact. Today, two major models for electricity commercialization operate in the United States. One is the regulated monopoly model, in which vertically integrated electricity providers are regulated by state commissions. The other is the competitive model, in which power producers can openly access transmission infrastructure and participate in wholesale electricity markets. This paper describes the origins, evolution, and current status of the regulations that enable competitive markets in the United States.

    Dating aggression occurs frequently in early to mid-adolescence and has negative repercussions for psychosocial adjustment and physical health. The patterns of behavior learned during this developmental timeframe may persist in future dating relationships, underscoring the need to identify risk factors for this outcome. The current study examined longitudinal relations between beliefs supporting aggression, anger regulation, and dating aggression. Participants were 176 middle school students in sixth, seventh, and eighth grade (50 % female; 82 % African American). No direct effects were found between beliefs supporting reactive or proactive aggression and dating aggression. Beliefs supporting reactive aggression predicted increased rates of anger dysregulation, and beliefs supporting proactive aggression led to subsequent increases in anger inhibition. Anger dysregulation and inhibition were associated with higher frequencies of dating aggression. An indirect effect was found for the relation between beliefs supporting reactive aggression and dating aggression via anger dysregulation. Another indirect effect emerged for the relation between beliefs supporting proactive aggression and dating aggression through anger inhibition. The study's findings suggested that beliefs supporting proactive and reactive aggression were differentially related to emotion regulation processes, and identified anger dysregulation and inhibition as risk factors for dating aggression among adolescents.

    This report is about the design of economic regulation of electricity companies in the Nordic countries. The purpose is to inform the interested reader on how the regulation of tariffs is designed. The intention is to give a short overview on the current economic regulation with an ambition to focus on differences and similarities. A common feature of the electricity distribution sector is that the industry structure consists of many independent companies with great differences in size and density of customers. This is contrary to what is common in other countries. The regulatory task can be more challenging with many separate utilities to regulate, especially if the industry is very heterogenous. In the appendices, the economic regulation of each country is presented in more detail. In the main text the focus is on differences and similarities. When comparing the regulations one can make two observations. On a superior level there are great similarities. All Nordic countries regulate the network companies by setting revenue caps. The legislation, the goals given to the regulators and the regulators general interpretation of the rules are to a great extent the same. The primary purposes are to prevent the monopolist to overcharge customers and to create a rational network industry. The regulation shall stimulate an effective management resulting in productivity development and optimal quality of the services. The differences in the Nordic economic regulations are in the details - in the setup of the regulatory models and choice of parameters. For instance; the assessment of a reasonable rate-of-return is done in all the regulations. When deciding this rate-of-return some countries use the method of weighted cost of capital (WACC) and capital asset pricing model (CAPM), other do not. Even when using the same method, the inputs in the model are not the same. Common for the regulatory models are the division of costs related to capital costs and operating costs. The

  18. Phosphorylation of connexin43 on serine 306 regulates electrical coupling

    DEFF Research Database (Denmark)

    Procida, Kristina; Jørgensen, Lone; Schmitt, Nicole

    2009-01-01

    BACKGROUND: Phosphorylation is a key regulatory event in controlling the function of the cardiac gap junction protein connexin43 (Cx43). Three new phosphorylation sites (S296, S297, S306) have been identified on Cx43; two of these sites (S297 and S306) are dephosphorylated during ischemia....... The functional significance of these new sites is currently unknown. OBJECTIVE: The purpose of this study was to examine the role of S296, S297, and S306 in the regulation of electrical intercellular communication. METHODS: To mimic constitutive dephosphorylation, serine was mutated to alanine at the three sites...... and expressed in HeLa cells. Electrical coupling and single channel measurements were performed by double patch clamp. Protein expression levels were assayed by western blotting, localization of Cx43, and phosphorylation of S306 by immunolabeling. Free hemichannels were assessed by biotinylation. RESULTS...

  19. Emotion Regulation Difficulties Moderate the Association Between Heavy Episodic Drinking and Dating Violence Perpetration Among College Men.

    2016-01-01

    Because of high rates of heavy drinking and dating violence (psychological or physical aggression toward a dating partner) among college men, we examined whether emotion regulation difficulties moderated the association between heavy drinking and dating violence perpetration. One hundred and fifty-eight men were recruited from a large northwestern US university between April 2014 and August 2014. Participants completed an online survey that assessed their emotion regulation difficulties as well as their past year history of heavy episodic drinking (HED; consuming 5+ drinks in 2 hours) and dating violence perpetration. Generalized linear models revealed that the positive association between HED and dating violence perpetration was stronger for men with greater impulse control difficulties and for those who reported limited access to emotion regulation strategies. In addition to continued efforts to reduce heavy drinking among college men, interventions targeting emotion regulation difficulties should be incorporated into standard dating violence intervention and prevention efforts to further reduce the likelihood of dating violence perpetration in this population.

  20. Assessment of Drought Stress and Planting Date Effects Applied on Original Plant, on its Seed Electrical Conductivity Rate

    2012-02-01

    Full Text Available In order to assess drought stress and planting date effects applied on original plant, on the electrical conductivity rate of the subsequent seeds, this research was performed in two parts at the Research Field and Laboratory during spring 2008. The field experiment was performed as a completely randomized block design (CRBD with 20 treatments and three replications. Treatments included the seeds of five cultivars of canola, two planting dates and two levels of irrigation, which in previous year (2006-2007 had been cultivated as a factorial split plot based on CRBD. In the field experiment the characteristics measured including: Final Emergence Percentage (FEP, Mean Time of Emerging (MTE, Mean Daily Emerging (MDE, Daily Emerging Speed (DES, and at the laboratory Electrical Conductivity (EC of the seed leakages was measured. Results indicated that there is no correlation between FEP and EC and so EC test cannot be used for predication the number of emerging plants in the field. In the results of variance analysis laboratory, the cultivar of Modena due to high level of EC had the lowest quality and other cultivars had no significant difference. The interaction between the time of exertion the stress × canola cultivars two cultivars, Opera and Modena had the lowest and the highest in after cutting off the irrigation during stem elongation and in normal irrigation, Sarigol had the lowest EC. The interaction between planting date × Canola cultivars, Modena cultivar in planting date two had highest EC and other cultivars had no significant difference with each other. Based on variance analysis field data planting date and drought stress had no significant effect on measured characteristics.

  6. An Examination of Emotion Regulation and Alcohol Use as Risk Factors for Female-Perpetrated Dating Violence.

    Science.gov (United States)

    Ortiz, Edwin; Shorey, Ryan C; Cornelius, Tara L

    2015-01-01

    Dating violence is a serious problem among college students. Research indicates that females perpetrate as much, if not more, psychological and physical aggression against their dating partners relative to their male counterparts. Unfortunately, there is considerably less research on risk factors for female-perpetrated dating violence, hindering efforts aimed at preventing violence in their relationships. This study examined 2 risk factors for female-perpetrated dating violence, namely alcohol use and emotion regulation, within a sample of undergraduate female college students (N = 379). Using structural equation modeling, results demonstrated that emotion regulation was associated with psychological aggression perpetration, and this was partially mediated by alcohol use. Moreover, a 2-chain mediation was present, such that emotion regulation deficits predicted alcohol use, which in turn predicted psychological aggression, which finally predicted physical aggression. These findings are consistent with theoretical models of dating violence and indicate that intervention programs should focus their efforts on increasing adaptive emotion regulation, decreasing alcohol use, and reducing psychological aggression.

    2013-01-01

    Verbal and physical dating aggression is prevalent among college-aged men and women, especially a pattern of mutual aggression in which both partners engage in aggression. Alcohol intoxication and anger arousal have both been implicated in the occurrence of aggression, and the ability to regulate one’s emotions may interact with both alcohol intoxication and emotional arousal to predict dating aggression. The current study is the first known experimental investigation to examine the effects of alcohol intoxication, alcohol expectancies, emotion regulation, and emotional arousal on dating aggression. Participants were randomized to receive alcohol (n=48), placebo (n=48), or no alcohol (n=48). Intoxicated men and women expressed more verbal and physical aggression intentions than those in the no alcohol condition, and individuals in the placebo condition did not significantly differ from those in the alcohol and no alcohol conditions. These results suggest that the pharmacological effects of alcohol were important to the occurrence of dating aggression, whereas the effects of expectancy are less clear. Among those less able to engage in cognitive reappraisal, individuals who consumed alcohol or believed they consumed alcohol expressed more verbal and physical aggression intentions than those who received no alcohol. Those with higher arousal who were better able to suppress their emotions expressed fewer verbal and physical aggression intentions than those with lower arousal. In addition to reducing alcohol consumption, interventions to prevent dating aggression might incorporate emotion regulation skills, with a focus on understanding the circumstances in which cognitive reappraisal and emotion suppression are relatively more effective.

    Full Text Available Nowadays the work is in progress to develop wheeled and caterpillar tractors with electromechanical transmission. Range of changes in transmission gear ratio while using propulsion electric motor depends on mechanical characteristics of a tractor propulsion electric motor which is equipped with electromechanical transmission. In case when the range is rather high then it is possible to minimize number of gearings in the tractor gearing box or exclude its usage at all. Type of the applied propulsion electric motor and regulation method specify type of mechanical characteristics (characteristics family of the propulsion electric motor.The paper considers a propulsion asynchronous electric motor with frequency control. While using frequency control it is possible to regulate electric motor revolutions by mutual changes in voltage and voltage frequency. There are various laws of mutual changes in voltage and frequency (regulation laws. Selection of a regulation law influences on type of mechanical characteristics of a propulsion electric motor. Application of any law can be admissible only for some specific range of voltage frequency otherwise it is possible to exceed some parameters (for example, admissible voltage in the winding of electric motor stator. It is necessary to ensure the required moment within wide range for a tractor propulsion electric motor. In this case losses in the electric motor must be minimal. Losses in the rotor of the propulsion asynchronous electric motor are directly proportional to its sliding and its best propulsion and mechanical properties of a mobile machine will be ensured in the case when sliding is preserved at a constant value. According to these reasons selection of regulation laws has been carried out for operation of the propulsion asynchronous electric motor with nominal sliding and mechanical characteristics at nominal sliding is conventionally called a nominal characteristics.The paper analyzes the possible

    In this contribution the authors provide an overview of regulatory issues and conflicts regarding electricity interconnectors between the Netherlands and its neighbours. The Electricity Act 1998 has assigned management of the Dutch part of the interconnectors to exclusively TenneT, the national transmission system operator in the Netherlands. The authors conclude that the dust of many regulatory problems and conflicts concerning existing interconnectors has settled down. The preliminary proceedings regarding the long Sep priority which are pending with the EU Court of Justice must still produce an answer as to the compatibility of this priority with community law. Regarding construction and management of new interconnectors many regulatory and commercial challenges lie ahead. As regards congestion management on existing interconnectors the authors raise the question whether concentration on increasing physical interconnector capacity is the right approach. Interconnector capacity, even if substantially expanded, will continue to be liable to falling short of demand due to price differences and volatility of prices in the various national markets. Perhaps more effort should be put into attaining conditions for non-transaction based congestion management. The combined UCTE (Union for the Co-ordination of Transmission of Electricity) grid is, technically speaking, a 'copper plate'. If it were only managed as such by the various national transmission system operators through co-ordinated control of production and load, almost all transports on this copper plate could be secured, irrespective of underlying commercial flows.

    Full Text Available With the antimonopoly regulation in the domestic economy getting more stringent an analysis of the current measures of antimonopoly regulation in terms of their efficiency is now becoming ever more relevant. The aim of the study - analyze how the measures of antimonopoly regulation affect competitive relationships in the electric power industry. The following methods have been used in this work: empirical method, cause-effect method and scientific abstraction method. The article sets out an analysis of the antimonopoly regulation measures that the antimonopoly authority applies. It also provides an assessment of consequences that follow from such methods being applied for the promotion of competitive relationships on the market of electric power and capacity. A conclusion has been reached that the antimonopoly regulation measures being applied impede the progress of competitive relationships on the market of electric power and capacity. The continuing process of reformation in electric power industry aims to liberalize relationships in the area of electric power production. Yet, as a result of this process, generating capacities are becoming increasingly more concentrated mainly around state companies. This is mainly caused by the lack of certainty regarding the results of the industry reformation and a more stringent state regulation over the last years of the reforms. At the same time, for the purposes of limiting the market force, measures of antimonopoly regulation are being applied to generating companies. Such measures have an adverse effect on competitive relationships and stimulate further concentration.

    Axonal growth cones are responsible for the correct guidance of developing axons and the establishment of functional neural networks. They are highly motile because of fast and continuous rearrangements of their actin-rich cytoskeleton. Here we have used live imaging of axonal growth cones of hippocampal neurons in culture and quantified their motility with a temporal resolution of 2 s. Using novel methods of analysis of growth cone dynamics, we show that transient activation of kainate receptors by bath-applied kainate induced a fast and reversible growth cone stalling. This effect depends on electrical activity and can be mimicked by the transient discharge of action potentials elicited in the neuron by intracellular current injections at the somatic level through a patch pipette. Growth cone stalling induced by electrical stimulation is mediated by calcium entry from the extracellular medium as well as by calcium release from intracellular stores that define spatially restricted microdomains directly affecting cytoskeletal dynamics. We propose that growth cone motility is dynamically controlled by transient bursts of spontaneous electrical activity, which constitutes a prominent feature of developing neural networks in vivo.

    Lipid nanotubes have great potential in biology and nanotechnology. Here we demonstrate a method to form lipid nanotubes using space-regulated AC electric fields above coplanar interdigitated electrodes. The AC electric field distribution can be regulated by solution height above the electrodes. The ratio of field component in x axis (Ex) to field component in z axis (Ez) increases dramatically at solution height below 50 μm; therefore, at lower solution height, the force from Ex predominantly drives lipids to form lipid nanotubes along with the electric field direction. The forces exerted on the lipid nanotube during its formation were analyzed in detail, and an equation was obtained to describe the relationship among nanotube length and field frequency, amplitude, and time. We believe that the presented approach opens a way to design and prepare nanoscale materials with unique structural and functional properties using space-regulated electric fields.

  10. From franchise to state commission: Regulation of the electric utility industry, 1907 to 1932

    Reutter, Keith Alan

    1997-09-01

    Empirical research into the effects of regulation on industry has been around since the early 1960s. Over the last thirty plus years a number of interesting results have been brought to the fore. For instance, it has been found that regulation of the trucking industry limits entry and increases prices. A similar result has been pointed to in other industries such as commercial airlines and banking. The effect of the state commission form of regulation on the electric utility industry has been less conclusive. State commissions became dominant during the period 1910-1930, replacing local franchising as a method of regulating the electric utility industry. Two competing theories suggest why this transformation took place, the "capture" and "public interest" theories of regulation. The capture theory of regulation suggests that the electric utility industry demanded state regulation as a way to earn above normal profits and reduce competition. The public interest theory suggests the purpose of regulation by state commissions was to benefit the general public by forcing the industry to be competitive. Few studies have tried to determine which theory more aptly describes the actual events that took place. The empirical model developed in Chapter V, is an extension of the current literature. A set of simultaneous equations describing the natural gas and electricity markets is estimated using cross-sectional time-series data from 1907 to 1932. The effect of regulation on the electric utility industry is modeled with a dummy variable taking on a value of one to designate that a state commission had been established. The results suggest the capture theory of regulation best describes the period under study. The empirical estimates indicate that state commissions (1) reduced the rate at which the real price of electricity was falling, (2) had a negative impact on firms entering the industry, (3) had a positive influence on the cost of producing a kwh of electricity, and (4

    Full Text Available The article identifies tendencies of development of international electric energy markets. It marks out the role of well-organised functioning of the electric energy market for maintaining the energy security of the country under complex conditions of Ukrainian economy transformation under the influence of geopolitical changes, financial, economic and social factors. It justifies important role of the state in realisation of the regulating impact through mechanisms of institutional support of production, transportation and supply of electric energy; it focuses on imperfection of the existing system of institutes of this sphere, which determine harmonicity of the electric energy buy and sell process. Based on the system analysis of the institutional foundation, which reflects principles and essence of regulation of the electric energy market and interrelations of its subjects, the article generalises problems of the modern regulatory and legal base and realisation of strategic programmes of development in the context of formation of relations between the energy market participants, which would facilitate renovation of state regulation. The article marks out key directions of solution of topical issues of institutional support of activity of electric energy market participants, the most urgent of which are problems of the tariff policy, alternative energy development, financial discipline and technical state of fixed assets of the electric energy complex. The article puts in order the system of contractual relations of subjects of the electric energy market, which allows formation of the scientifically justified approaches in the direction of improvement of the organisational structure of the energy market and introduction of measures on increase of efficiency of regulating actions by the state.

  17. Electrical signals as mechanism of photosynthesis regulation in plants.

    Science.gov (United States)

    Sukhov, Vladimir

    2016-12-01

    This review summarizes current works concerning the effects of electrical signals (ESs) on photosynthesis, the mechanisms of the effects, and its physiological role in plants. Local irritations of plants induce various photosynthetic responses in intact leaves, including fast and long-term inactivation of photosynthesis, and its activation. Irritation-induced ESs, including action potential, variation potential, and system potential, probably causes the photosynthetic responses in intact leaves. Probable mechanisms of induction of fast inactivation of photosynthesis are associated with Ca(2+)- and (or) H(+)-influxes during ESs generation; long-term inactivation of photosynthesis might be caused by Ca(2+)- and (or) H(+)-influxes, production of abscisic and jasmonic acids, and inactivation of phloem H(+)-sucrose symporters. It is probable that subsequent development of inactivation of photosynthesis is mainly associated with decreased CO2 influx and inactivation of the photosynthetic dark reactions, which induces decreased photochemical quantum yields of photosystems I and II and increased non-photochemical quenching of photosystem II fluorescence and cyclic electron flow around photosystem I. However, other pathways of the ESs influence on the photosynthetic light reactions are also possible. One of them might be associated with ES-connected acidification of chloroplast stroma inducing ferredoxin-NADP(+) reductase accumulation at the thylakoids in Tic62 and TROL complexes. Mechanisms of ES-induced activation of photosynthesis require further investigation. The probable ultimate effect of ES-induced photosynthetic responses in plant life is the increased photosynthetic machinery resistance to stressors, including high and low temperatures, and enhanced whole-plant resistance to environmental factors at least during 1 h after irritation.

    2003-11-01

    The regulation of distribution utilities is evolving from the traditional approach based on a cost of service or rate of return remuneration, to ways of regulation more specifically focused on providing incentives for improving efficiency, known as performance-based regulation or ratemaking. Modern regulation systems are also, to a higher degree than previously, intended to simulate competitive market conditions. The Market Design 2003-conference gathered people from 18 countries to discuss 'Methods to regulate unbundled transmission and distribution business on electricity markets'. Speakers from nine different countries and backgrounds (academics, industry and regulatory) presented their experiences and most recent works on how to make the regulation of unbundled distribution business as accurate as possible. This paper does not claim to be a fully representative summary of everything that was presented or discussed during the conference. Rather, it is a purposely restricted document where we focus on a few central themes and experiences from different countries.

    This report estimates the effects of regulated trade among the Scandinavian countries in a socio-economic perspective. Model simulations indicate that free trade is advantageous to Norway. In the short term foreign trade serves first of all to even out the effects of a variable supply of water to the hydroelectric power plants. In the long term trade with the other countries is connected primarily with peak load export/low load import. Free trade is advantageous to Denmark and Finland as well. In the short term free trade is essential for achieving a reasonably effective competition in the Swedish market. Simulations indicate, however, that in the long term Sweden may profit from trade regulations. 19 refs., 41 figs., 7 tabs.

    Full Text Available The game models were used to study the mechanism of coal-electricity price conflict under conditions of double price regulations of coal and electricity. Based on this, the peak shaving reserve mechanism was designed to probe into the countermeasures against the coal-electricity price conflicts. The study revealed that in the boom seasons of coal demand, the initiatives of the coal enterprises to supply thermal coal and the electricity enterprises to order thermal coal are reduced under conditions of double price regulations. However, under the circumstances of coal price marketization, in the boom seasons of coal demand the thermal coal price may go up obviously, the initiatives of the coal enterprises to supply thermal coal are increased, and meanwhile the initiatives of the power enterprises to order thermal coal are decreased dramatically. The transportation capacity constraint of coal supply leads to the evident decrease of the initiatives of coal enterprises for the thermal coal supply. The mechanism of peak shaving reserve of thermal coal may not only reduce the price of coal market but also increase the enthusiasm of the power enterprises to order more thermal coal and the initiatives of the coal enterprises to supply more thermal coal.

    Electricity has a long history of being used as an alternative clinical treatment and as an effective approach to modifying cellular behaviours in vitro. It has been difficult, however, to take advantage of this modality in tissue generation because of the lack of suitable conductive, biocompatible scaffolding materials. In this study, in order to electrically regulate cell activities, a largely biodegradable conductor made of 5% conductive polypyrrole and 95% biodegradable poly(L-lactide) (PPy/PLLA) was prepared. Human cutaneous fibroblasts were cultured on the conductors in the presence or absence of a direct current (DC) electrical field (EF) of 50 mV/mm. The growth of the cells was characterized using fluorescent staining, SEM, and a MTT assay. The RNA expressions of interleukin-6 (IL-6) and interleukin-8 (IL-8) were assayed by RT-PCR. The amounts of IL-6 and IL-8 secreted by the fibroblasts were quantified by ELISA. The results showed that the PPy/PLLA conductors supported cell adhesion, spreading, and proliferation in both the presence and absence of the EF. Electrical stimulation (ES) applied through PPy/PLLA conductors dramatically enhanced cytokine secretion approximately 10-fold when compared to the non-ES controls. This effect lasted several days after the end of the ES. These findings highlight for the first time the possibility of a potent, effective approach to regulating tissue regeneration in conductive scaffolds through ES-modulated cytokine secretion, and to increasing cytokine productivity for biotechnological applications.

    When one leaf of a tomato plant is electrically-stimulated or heat-wounded, proteinase inhibitor genes are rapidly up-regulated in distant leaves. The identity of the systemic wound signal(s) is not yet known, but major candidates include hormones transmitted via the phloem or the xylem, the electrically-stimulated self-propagating electrical signal in the phloem (the action potential, AP), or the heat-wound-induced surge in hydraulic pressure in the xylem evoking a local change in membrane potential in adjacent living cells (the variation potential, VP). In order to discriminate between these signals we have adopted two approaches. The first approach involves applying stimuli that evoke known signals and determining whether these signals have similar effects on the "model" transcripts for proteinase inhibitors (pin) and calmodulin (cal). Here we show that a heat wound almost invariably evokes a VP, while an electrical stimulation occasionally evokes an AP, and both of these signals induce accumulation of transcripts encoding proteinase inhibitors. The second approach involves identifying the array of genes turned on by heat-wounding. To this end, we have constructed a subtractive library for heat-wounded tissue, isolated over 800 putatively up-regulated clones, and shown that all but two of the fifty that we have analyzed by Northern hybridization are, indeed, up-regulated. Here we show the early kinetics of up-regulation of three of these transcripts in the terminal (4th) leaf in response to heat-wounding the 3rd leaf, about 5 cm away. Even though these transcripts show somewhat different time courses of induction, with one peaking at 30 min, another at 15 min, and another at 5 min after flaming of a distant leaf, they all exhibit a similar pattern, i.e., a transient period of transcript accumulation preceding a period of transcript decrease, followed by a second period of transcript accumulation.

    There is a growing need to understand muscle cell behaviors and to engineer muscle tissues to replace defective tissues in the body. Despite a long history of the clinical use of electric fields for muscle tissues in vivo, electrical stimulation (ES) has recently gained significant attention as a powerful tool for regulating muscle cell behaviors in vitro. ES aims to mimic the electrical environment of electroactive muscle cells (e.g., cardiac or skeletal muscle cells) by helping to regulate cell-cell and cell-extracellular matrix (ECM) interactions. As a result, it can be used to enhance the alignment and differentiation of skeletal or cardiac muscle cells and to aid in engineering of functional muscle tissues. Additionally, ES can be used to control and monitor force generation and electrophysiological activity of muscle tissues for bio-actuation and drug-screening applications in a simple, high-throughput, and reproducible manner. In this review paper, we briefly describe the importance of ES in regulating muscle cell behaviors in vitro, as well as the major challenges and prospective potential associated with ES in the context of muscle tissue engineering.

  11. Plug-in hybrid electric vehicles as a source of distributed frequency regulation

    Mullen, Sara Kathryn

    The movement to transform the North American power grid into a smart grid may be accomplished by expanding integrated sensing, communications, and control technologies to include every part of the grid to the point of end-use. Plug-in hybrid electric vehicles (PHEV) provide an opportunity for small-scale distributed storage while they are plugged-in. With large numbers of PHEV and the communications and sensing associated with the smart grid, PHEV could provide ancillary services for the grid. Frequency regulation is an ideal service for PHEV because the duration of supply is short (order of minutes) and it is the highest priced ancillary service on the market offering greater financial returns for vehicle owners. Using Simulink a power system simulator modeling the IEEE 14 Bus System was combined with a model of PHEV charging and the controllers which facilitate vehicle-to-grid (V2G) regulation supply. The system includes a V2G controller for each vehicle which makes regulation supply decisions based on battery state, user preferences, and the recommended level of supply. A PHEV coordinator controller located higher in the system has access to reliable frequency measurements and can determine a suitable local automatic generation control (AGC) raise/lower signal for participating vehicles. A first step implementation of the V2G supply system where battery charging is modulated to provide regulation was developed. The system was simulated following a step change in loading using three scenarios: (1) Central generating units provide frequency regulation, (2) PHEV contribute to primary regulation analogous to generator speed governor control, and (3) PHEV contribute to primary and secondary regulation using an additional integral term in the PHEV control signal. In both cases the additional regulation provided by PHEV reduced the area control error (ACE) compared to the base case. Unique contributions resulting from this work include: (1) Studied PHEV energy systems

    A mandatory condition to ensure normal operation of a power system and efficiency in the sector is standardization and legal regulation of technological activities of electric power engineering entities and consumers. Compared to the times of USSR, the present-time technical guidance documents are not mandatory to follow in most cases, being of an advisory nature due to the lack of new ones. During the last five years, the industry has been showing a deterioration of the situation in terms of ensuring reliability and engineering controllability as a result of the dominant impact of short-term market stimuli and the differences in basic technological policies. In absence of clear requirements regarding the engineering aspects of such activities, production operation does not contribute to the preserving of technical integrity of the Russian power system, which leads to the loss of performance capability and controllability and causes disturbances in the power supply to consumers. The result of this problem is a high rate of accident incidence. The dynamics of accidents by the type of equipment is given, indicating a persisting trend of growth in the number of accidents, which are of a systematic nature. Several problematic aspects of engineering activities of electric power engineering entities, requiring standardization and legal regulation are pointed out: in the domestic power system, a large number of power electrotechnical and generating equipment operate along with systems of regulation, which do not comply with the principles and technical rules representing a framework where the Energy System of Russia is built and functioning

    2016-01-01

    Full Text Available In order to improve the power indices and to simplify the system of frequency speed control the scope of application of synchronous variable-frequency electric drives with independent frequency setting is being expanded. The synchronous motors with electromagnetic excitation and permanent magnet excitation in various industrial settings, including load-lifting machines and mechanisms, are used. As compared with the asynchronous frequency-regulated electric drives the synchronous ones have lower power loss, harder mechanical characteristic without feedback for speed and the simplest law of frequency control, i. e., a proportional one that, however, provides the maximum electromagnetic torque of the motor constant at all frequencies, due to the constant magnetic flux. The article concerns an analytical study of transient processes of synchronous electric drive with consideration of the influence of damping winding when the motor supply voltage frequency varies linearly during the transient time. As a result of the analysis the formulas have been obtained that make it possible to calculate the angular velocity of the rotor and the electromagnetic torque of the motor at start-up, braking, and impingement and discharge of loads, evaluating the quality of the transition process and tracking the maximum value of the electromagnetic torque, that must not exceed the permissible value. Validation of the developed technique of calculation of transient processes of synchronous electric drive has been obtained by comparison of calculations according to the formulas with the simulation results of the electric drive on the basis of the synchronous motor of the SD3 13-34-6 type (power of 500 kW and voltage of 6 kV.

    Merger analysis is usually drawing on concepts derived from competitive horizontal markets, such as market concentration, predatory foreclosure and economies of scale in marketing. In evaluating horizontal mergers among energy network operators, regulators must use different tools to evaluate...... the attractiveness of mergers. Norway is one country having implemented an ex ante regulation for mergers among electricity distribution operators (DSOs). We investigate whether the actual mergers of Norwegian DSOs in the period 1995-2004 can be rationalized as cost saving exercises or whether they should...... be interpreted in other ways. We use Data Envelopment Analysis (DEA) to estimate the potential cost savings from mergers ex ante, and we decompose the gains into gains from learning best practice and from improving economies of scale and scope. Moreover, we compare the sources of post merger performance...

    The paper is an analysis of two-positions (hysteresis) regulators, self-tuned PID controller and PID controller for temperature control used for indirect heat resistance furnaces. For PID controller was used three methods of tuning: Ziegler-Nichols step response model, Cohen-Coon tuning rules and Ziegler-Nichols tuning rules. In experiments it used an electric furnace with indirect heating with active power of resistance of 1 kW/230V AC and a numerical temperature regulator AT-503 type (ANLY). It got a much better temperature control when using the Cohen-Coon tuning rules method than those of Ziegler-Nichols step response method and Ziegler-Nichols tuning rules method.

    Electric utilities today must contain costs at a time when many need to modernize aging systems and all face major changes in technologies, customer preferences and competitive pressures.Most U.S. electric utility facilities are investor-owned, subject to rate and service regulation by state public utility commissions. Regulatory systems under which these utilities operate affect their performance and ability to meet these challenges. In this business environment, multiyear rate plans have some advantages over traditional rate regulation.The report focuses on key design issues and provides case studies of the multiyear rate plan approach, applicable to both vertically integrated and restructured states. Mark Newton Lowry and Matt Makos of Pacific Energy Group Research and Jeff Deason of Berkeley Lab authored the report; Lisa Schwartz, Berkeley Lab, was project manager and technical editor.The report is aimed primarily at state utility regulators and stakeholders in the state regulatory process. The multiyear rate approach also provides ideas on how to streamline oversight of public power utilities and rural electric cooperatives for their governing boards.Two key provisions of multiyear rate plans strengthen cost containment incentives and streamline regulation: 1. Reducing frequency of rate cases, typically to every four or five years 2. Using an attrition relief mechanism to escalate rates or revenue between rate cases to address cost pressures such as inflation and growth in number of customers, independently of the utility’s own cost Better utility performance can be achieved under well-designed multiyear rate plans while achieving lower regulatory costs. Benefits can be shared between utilities and their customers. But plans can be complex and involve significant changes in the regulatory system. Designing plans that stimulate utility performance without undue risk and share benefits fairly can be challenging.This report discusses the rationale for multiyear

  20. The homeobox transcription factor Even-skipped regulates acquisition of electrical properties in Drosophila neurons

    Directory of Open Access Journals (Sweden)

    2006-11-01

    Full Text Available Abstract Background While developmental processes such as axon pathfinding and synapse formation have been characterized in detail, comparatively less is known of the intrinsic developmental mechanisms that regulate transcription of ion channel genes in embryonic neurons. Early decisions, including motoneuron axon targeting, are orchestrated by a cohort of transcription factors that act together in a combinatorial manner. These transcription factors include Even-skipped (Eve, islet and Lim3. The perdurance of these factors in late embryonic neurons is, however, indicative that they might also regulate additional aspects of neuron development, including the acquisition of electrical properties. Results To test the hypothesis that a combinatorial code transcription factor is also able to influence the acquisition of electrical properties in embryonic neurons we utilized the molecular genetics of Drosophila to manipulate the expression of Eve in identified motoneurons. We show that increasing expression of this transcription factor, in two Eve-positive motoneurons (aCC and RP2, is indeed sufficient to affect the electrical properties of these neurons in early first instar larvae. Specifically, we observed a decrease in both the fast K+ conductance (IKfast and amplitude of quantal cholinergic synaptic input. We used charybdotoxin to pharmacologically separate the individual components of IKfast to show that increased Eve specifically down regulates the Slowpoke (a BK Ca2+-gated potassium channel, but not Shal, component of this current. Identification of target genes for Eve, using DNA adenine methyltransferase identification, revealed strong binding sites in slowpoke and nAcRα-96Aa (a nicotinic acetylcholine receptor subunit. Verification using real-time PCR shows that pan-neuronal expression of eve is sufficient to repress transcripts for both slo and nAcRα-96Aa. Conclusion Taken together, our findings demonstrate, for the first time, that Eve

    Leptin, a peptide hormone produced by adipocytes, is recognized as one of the signals involved in the onset of reproductive activity. The leptin receptor has been found in hypothalamic neurons and pituitary gonadotropes, suggesting that the hormone may act at both sites to stimulate the secretion of GnRH and consequently, FSH and LH. In response to a stimulus such as a hypothalamic secretagogue, gonadotropes respond with changes in electrical activity, intracellular Ca(2+) and hormone release. The main aim of this report was to investigate whether leptin promotes a change in the electrical and secretory activities of bovine gonadotropes. After 48 h of treatment with leptin (10 nM) significant changes in the action potential properties were observed in gonadotropes, which included an increase in amplitude, time-to-pike and post-hyperpolarization, as well as a decrease in firing threshold. Likewise, leptin induced a significant (∼1.3-fold) up-regulation of voltage-gated Na(+) channel current density, and a selective increase (∼2.1-fold) in Ca(2+) current density through high voltage-activated channels. Consistent with this, leptin enhanced GnRH-induced secretion of LH measured by ELISA. We suggest that leptin enhances membrane expression of voltage-gated Na(+) and Ca(2+) channels, which results in a modulation of the action potential properties and an increase in hormone release from gonadotropes.

    The disposal and recovery of plastics from waste electrical and electronic equipment (WEEE) are of considerable importance, both from an environmental and an economic perspective. This paper presents the results of a study investigating current concentrations of hazardous substances in mixed plastics from WEEE and their implications for an environmentally sound recovery. The study included 53 sampling campaigns for mixed plastics from WEEE. The samples were analyzed with regard to heavy metals (cadmium, chromium, mercury, and lead) and flame retardants (PentaBDE, OctaBDE, DecaBDE, DecaBB) regulated in the RoHS Directive. Besides these substances, other brominated flame retardants known to occur in electronics (HBCD, TBBPA) as well as the total bromine and phosphorus contents were considered. Results show that no mixed plastics fraction from WEEE is completely free from substances regulated in the RoHS Directive. The lowest number and average concentrations were found in flat screen monitors. The highest concentrations were found in mixed plastics from CRT monitors and TVs. Mixed plastics fractions with high average concentrations of heavy metals originate from the treatment of small household appliances (cadmium), ICT equipment (lead), and consumer equipment (lead). Mixed plastics fractions with high average concentrations of brominated flame retardants mainly originate from the treatment of small household appliances for high temperature applications (DecaBDE), CRT monitors (OctaBDE and DecaBDE) and consumer equipment (DecaBDE), in particular CRT TVs (DecaBDE). To avoid a dissipation of hazardous substances into plastics and the environment, it is recommended that mixed plastics from WEEE are subject to a strict quality management.

  13. Acceleration Slip Regulation Strategy for Distributed Drive Electric Vehicles with Independent Front Axle Drive Motors

    Directory of Open Access Journals (Sweden)

    Lingfei Wu

    2015-05-01

    Full Text Available This paper presents an acceleration slip regulation strategy for distributed drive electric vehicles with two motors on the front axle. The tasks of the strategy include controlling the slip ratio to make full use of the road grip and controlling the yaw rate to eliminate the lateral movement due to the difference between motor torques. The rate of the slip ratio change can be controlled by controlling the motor torque, so that the slip ratio can be controlled by applying a proportional-integral control strategy to control the rate of the slip ratio change. The yaw rate can be controlled to almost zero by applying torque compensation based on yaw rate feedback. A coordination control strategy for the slip ratio control and yaw rate control is proposed based on analysis of the priorities and features of the two control processes. Simulations were carried out using MATLAB/Simulink, and experiments were performed on a hardware-in-loop test bench with actual motors. The results of the simulations and experiments showed that the proposed strategy could improve the longitudinal driving performance and straight line driving stability of the vehicle.

  15. A minimal dose of electrically induced muscle activity regulates distinct gene signaling pathways in humans with spinal cord injury.

    Directory of Open Access Journals (Sweden)

    Michael A Petrie

    Full Text Available Paralysis after a spinal cord injury (SCI induces physiological adaptations that compromise the musculoskeletal and metabolic systems. Unlike non-SCI individuals, people with spinal cord injury experience minimal muscle activity which compromises optimal glucose utilization and metabolic control. Acute or chronic muscle activity, induced through electrical stimulation, may regulate key genes that enhance oxidative metabolism in paralyzed muscle. We investigated the short and long term effects of electrically induced exercise on mRNA expression of human paralyzed muscle. We developed an exercise dose that activated the muscle for only 0.6% of the day. The short term effects were assessed 3 hours after a single dose of exercise, while the long term effects were assessed after training 5 days per week for at least one year (adherence 81%. We found a single dose of exercise regulated 117 biological pathways as compared to 35 pathways after one year of training. A single dose of electrical stimulation increased the mRNA expression of transcriptional, translational, and enzyme regulators of metabolism important to shift muscle toward an oxidative phenotype (PGC-1α, NR4A3, IFRD1, ABRA, PDK4. However, chronic training increased the mRNA expression of specific metabolic pathway genes (BRP44, BRP44L, SDHB, ACADVL, mitochondrial fission and fusion genes (MFF, MFN1, MFN2, and slow muscle fiber genes (MYH6, MYH7, MYL3, MYL2. These findings support that a dose of electrical stimulation (∼10 minutes/day regulates metabolic gene signaling pathways in human paralyzed muscle. Regulating these pathways early after SCI may contribute to reducing diabetes in people with longstanding paralysis from SCI.

  3. Measurement of Heat Losses on The Milking Machine Electric Motor at Various Regulations of Vacuum Using Methods of Thermal Imagery

    Directory of Open Access Journals (Sweden)

    Jan Kudělka

    2014-01-01

    Full Text Available To ensure the desirable vacuum in the milking machines, use is currently made predominantly of rotary vacuum pumps. These vacuum pumps are driven by a squirrel-cage induction motor. Until recently, the vacuum in the system to achieve the required value was controlled by a main control valve sucking in ambient air into the system. During the milking process itself and during other activities (flushing, sanitation, this control method consumed a large amount of electricity. The technical solution to electricity demand reduction was introduced with the emergence and development of frequency converters. The frequency converters control the operation of the asynchronous electric motor so that the actual delivery of the vacuum pumps equals the volume of air sucked into the vacuum pipe. The motor supply by the frequency converter brings about a host of adverse phenomena. This paper is dedicated to motor heating and heat losses on the surface of the electric motor at different regulations of vacuum in milking machines. The objective of the paper is to determine the immediate specific heat flows along the surface of the electric motor of the milking machine during milking using a control valve regulation and a control using the frequency converter, and compare the resulting value. The specific heat flows were determined by means of a non-traditional method of temperature field measurement using a system of thermal imagery. The calculated and measured data obtained from both these systems were statistically evaluated and compared. Use was made of a milking machine located in the cooperative Hospodářské obchodní družstvo (HOD Jabloňov.

    In the biological nervous system, synaptic plasticity regulation is based on the modulation of ionic fluxes, and such regulation was regarded as the fundamental mechanism underlying memory and learning. Inspired by such biological strategies, indium-gallium-zinc-oxide (IGZO) electric-double-layer (EDL) transistors gated by aqueous solutions were proposed for synaptic behavior emulations. Short-term synaptic plasticity, such as paired-pulse facilitation, high-pass filtering, and orientation tuning, was experimentally emulated in these EDL transistors. Most importantly, we found that such short-term synaptic plasticity can be effectively regulated by alcohol (ethyl alcohol) and salt (potassium chloride) additives. Our results suggest that solution gated oxide-based EDL transistors could act as the platforms for short-term synaptic plasticity emulation.

    Full Text Available The power sector is critical to the development of any country and Nigeria is no exception, incessant power outrage has been the bane of economic development in the country. For the past three decades, the power sector of the country has been plagued by a lot of problems ranging from low power generation and distribution, decaying facilities most of which were commissioned before and shortly after the country’s independence. The interaction of the electric power industry with climate is manifested both in the effect that severe weather has on the power system and through the contribution of electric power to the production of greenhouse gas (GHG and other pollutants.The paper examines and provides answers to (i the nature of consumers’ attitudes towards power consumption and (ii suggest ways of informing the consumers on the need to conserve power when not in use. This study was carried out in Alimosho Local Government Area of Lagos State, south-west Nigeria. The findings show that 61 percent of electricity consumers’ agreed that rationing of electricity consumption would stabilized the electricity distribution, whereas 39 percent were not in agreement. The study also shows that about 90 percent of the consumers were not satisfied with the services being offered by the Government owned company, while the remaining 10 percent were satisfied. We suggest the authority take to prepaid method of electricity consumption and also intensify efforts to enlighten the public on the need to conserve power.

    Companies that hope to succeed in converging energy service business must plan to trade bundled and unbundled energy commodities in paper as well as physical markets. The winners will be those who realize the immensity and crucial importance of the former. Many traditional electric utilities are spending most of their time defensively on stranded asset issues, and only token amounts of time proactively on how to become a Btu company. The vacuum they are creating is being filled by those companies - Enron, UtiliCorp United, Duke Power, and a few others who have made preparing for the future their core mission rather than a sideshow. Important as the stranded asset issue is - and it is especially critical in nuclear-heavy regions like New England - the author believes that senior executives of all electric utilities must immediately relegate this {open_quotes}work of the past{close_quotes} to second place. It is urgent that they now begin to do what Enron decided to do almost ten years ago: acknowledge that an enormous paradigm shift has taken place in the energy industry and devote all available brainpower to preparing for that change. Electric utilities are on the threshold of an era in which electricity prices will be determined, not only by supply and demand as traditionally understood, but by the supply and demand for electricity in paper markets. In traditional market nomenclature, prices are determined by supply and demand. In paper markets, while the analytical metaphor is identical, the language and dynamics are different: Prices will emerge from the interplay of those who are {open_quotes}short{close_quotes} (i.e., willing to sell in the power futures markets at given prices). Electric utilities must master the dynamics of both markets. No less than their corporate survival is at stake.

  15. Real option valuation of a decremental regulation service provided by electricity storage.

    Science.gov (United States)

    Szabó, Dávid Zoltán; Martyr, Randall

    2017-08-13

    This paper is a quantitative study of a reserve contract for real-time balancing of a power system. Under this contract, the owner of a storage device, such as a battery, helps smooth fluctuations in electricity demand and supply by using the device to increase electricity consumption. The battery owner must be able to provide immediate physical cover, and should therefore have sufficient storage available in the battery before entering the contract. Accordingly, the following problem can be formulated for the battery owner: determine the optimal time to enter the contract and, if necessary, the optimal time to discharge electricity before entering the contract. This problem is formulated as one of optimal stopping, and is solved explicitly in terms of the model parameters and instantaneous values of the power system imbalance. The optimal operational strategies thus obtained ensure that the battery owner has positive expected economic profit from the contract. Furthermore, they provide explicit conditions under which the optimal discharge time is consistent with the overall objective of power system balancing. This paper also carries out a preliminary investigation of the 'lifetime value' aggregated from an infinite sequence of these balancing reserve contracts. This lifetime value, which can be viewed as a single project valuation of the battery, is shown to be positive and bounded. Therefore, in the long run such reserve contracts can be beneficial to commercial operators of electricity storage, while reducing some of the financial and operational risks in power system balancing.This article is part of the themed issue 'Energy management: flexibility, risk and optimization'. © 2017 The Author(s).

    1999-03-01

    Wind power is facing the dual challenge of entering a liberated electricity market and at the same time being one of the main contributors to the reduction of greenhouse gas emissions. The paper analyses the importance of the existing standard payment schemes in the development of wind power, and how this might be affected by the introduction of a liberated electricity market. The existing Danish standard payment scheme has strongly encouraged investments in wind turbines. It has been and still is very effective in promoting a high wind power capacity development, but at a high economic cost to the Danish Government. Different models of conditions for wind power at an electricity exchange do exist, but all seem to introduce a higher risk to the individual wind turbine owner than seen with the present payment scheme. In short it might be stated that going from the existing standard payment system to a market based system, the political uncertainty is converted to a market risk for the individual wind turbine owner.

    Directory of Open Access Journals (Sweden)

    Anastasiia Koliesnichenko

    2017-11-01

    Full Text Available The article presents the problems of current trends in the development of the electric power industry in conditions of increasing capital concentration, informing the economy and increasing the dynamics of the movement of significant amounts of cash flows which require a permanent analysis of the current situation and the necessary adjustment and / or modification of the parameters for the regulation of energy markets. From this article it can be concluded that the task of constructing forecasts acquires high relevance in many subject areas. It is an integral component of the daily work of modern social and economical systems. The interrelations of the subjects of the electric energy market are the one of the its most important institutions. The purpose of this article is to study the theoretical basis for the adaptive application of forecasting methods in the functioning of energy markets. In order to avoid the dominance of commercial interests of certain groups of participants in the energy market, the emergence of price distortions in the market that have a destructive effect on obtaining potential benefits from the introduction of competitive mechanisms, the key to finding the most effective and economical way to solve these problems is the use of systemic regulation of emerging deviations in achieving target milestones especially in the context of reform. The informational and analytical support formation for the performance of the functions assigned to the regulatory apparatus requires the use of forecasting methods and approaches to preserve the dynamic development of the electric energy market and to maintain the balance of interests of all its subjects in the conditions of reform. The article uses a number of methods: classification and systematization in the analysis of scientific methods for forecasting and planning social and economic processes, logical generalization when reviewing existing modeling methods and assessing their

    2000-12-01

    So far the results of the electricity reform in April 1999 have fallen short of expectations, since the spaces for free market and competition are still very thin in our power system. The regulator's activity has to be appraised within these spaces. An early, though difficult and approximate, analysis indicates that there are at least two major objections to the Electric Authority's activity: the excessive pervasiveness of regulation and the long times required for its implementation. [Italian] La riforma elettrica dell'aprile 1999 ha sortito sinora risultati ben lontani da quelli attesi, creando solo esigui spazi di libero mercato e di concorrenza nel nostro sistema elettrico. All'interno di questi spazi, come valutare l'operato del regolatore? Da un primo, seppur difficoltoso e approssimativo, bilancio paiono potersi muovere almeno due principali critiche all'operato dell'Autorita' elettrica: l'eccesso di pervasivita' della regolazione e la lunghezza dei tempi di attuazione della stessa.

    This paper is based on the Brazilian electric sector to outline parallels for introduction of hydrogen as energetic vector in Brazilian matrix. For this purpose it was achieved an analysis of regulation theory, of electric sector reorganization, the new model of energy trade and the NOS role. In face of this analysis, hydrogen regulation may be established through a mix of four models: tariff model by return tax; tariff by marginal cost; regulation by performance and price cap. This new industrial sector should start vertical and with its maturity become non vertical as electric sector after its reorganization. Regarding the market, advanced purchase of hydrogen should be established enabling the reduction of incertitude in trade as well as reduction of implantation costs. NOS should pursue electric energy generation from hydrogen as this may carry impacts in transmission networks as well as in distribution network depending on how hydrogen was generated, whether in large scale or for local consumption supply.

  3. Two essays on electricity markets: Entry into hydroelectric generation industry and the political cycle of regulated prices

    Science.gov (United States)

    Moita, Rodrigo Menon Simoes

    This dissertation is about the electricity industry and the problems that arise with the liberalization and de-regulation of the industry. Characteristics intrinsic to the electricity market create problems that can compromise an efficient functioning of this market. Each of the two chapters of this dissertation focus on a specific aspect of this industry. The first chapter analyzes entry in the hydroelectric generation industry. The operation of a generator upstream regularizes the river flow for generators located downstream on the same river, increasing the production capacity of the latter. This positive externality increases the attractiveness of the locations downstream whenever a generator decides to enter upstream. Therefore, the entry decision of a generator in a given location may affect all entry decisions in potential locations for plants located downstream. I first model the problem of generators located in cascade on the same river and show the positive effect of the externality. Second, I use a panel of data on investment decisions of hydro-generation firms to estimate an entry model that takes into account the effect of the externality generated by entry upriver. The results show a positive incentive to locate downstream from existing plants and from locations where entry is likely to occur. Location characteristics also play an important role on the entrants' decisions. The model provides estimates of the average expected market price across the different years covered by the sample and shows that it rose one year before the energy crisis of 2001, evidencing that the market anticipated the crisis. This result has important implications on the evaluation of the Brazilian market design. It shows that entry responded to a rise in expectations about excess demand in the future, contradicting the argument that the crisis was a consequence of mis-designed market institutions. The second chapter deals with the problem of the political cycle in regulated

    2016-01-01

    Full Text Available Pudendal nerve plays an important role in urine storage and voiding. Our hypothesis is that a neuroprosthetic device placed in the pudendal nerve trunk can modulate bladder function after suprasacral spinal cord injury. We had confirmed the inhibitory pudendal-to-bladder reflex by stimulating either the branch or the trunk of the pudendal nerve. This study explored the excitatory pudendal-to-bladder reflex in beagle dogs, with intact or injured spinal cord, by electrical stimulation of the pudendal nerve trunk. The optimal stimulation frequency was approximately 15-25 Hz. This excitatory effect was dependent to some extent on the bladder volume. We conclude that stimulation of the pudendal nerve trunk is a promising method to modulate bladder function.

  7. Transcutaneous electrical nerve stimulation regulates organ blood flow and apoptosis during controlled hypotension in dogs.

    Directory of Open Access Journals (Sweden)

    Lele Zhang

    Full Text Available Transcutaneous electrical nerve stimulation (TENS is commonly used in clinical practice for alleviating pains and physiological disorders. It has been reported that TENS could counteract the ischemic injury happened in some vital organs. To determine the protective effect of TENS on internal organs during CH in dogs, target hypotension was maintained for 60 min at 50% of the baseline mean arterial pressure (MAP. The perfusion to the brain, liver, stomach, and kidney was recorded and apoptosis within these organs was observed. Results showed that when arriving at the target MAP, and during the maintaining stage for 10 min, perfusion to the stomach and liver in the CH+TENS group was much higher than in the CH group (P<0.05. Perfusion to the cerebral cortex greatly declined in both the controlled pressure groups when compared with the general anesthesia (GA group (P<0.05. After withdrawing CH, the hepatic blood flow in both the CH and CH+TENS groups, and the gastric and cerebral cortical blood flow in the CH+TENS group, were rapidly increased. By the end of MAP restoration, gastric blood flow in the CH group was still low. At 72 h after applying CH, terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL-positive cells in stomach and kidney tissue from the CH group were significantly increased compared with those in the GA group (P<0.05. There was no significant difference in TUNEL-positive cells in the liver and hippocampus among the three groups. Our results demonstrated that CH with a 50% MAP level could cause lower perfusion to the liver, stomach, cerebral cortex, and kidney, with apoptosis subsequently occurring in the stomach and kidney. TENS combined GA is able to improve the blood flow to the liver, stomach, and reduce the apoptosis in the stomach and kidney.

    The objective of this study was to investigate the effects and mechanism of Transcutaneous Electrical Nerve Stimulation (TENS) on the diabetic cytopathy (DCP) in the diabetic bladder. A total of 45 rats were randomly divided into diabetes mellitus (DM)/TENS group (n=15), DM group (n=15) and control group (n=15). The rats in the DM/TENS and TENS groups were electronically stimulated (stimulating parameters: intensity-31 V, frequency-31 Hz, and duration of stimulation of 15 min) for three weeks. Bladder histology, urodynamics and contractile responses to field stimulation and carbachol were determined. The expression of calcitonin gene-related peptide (CGRP) was analyzed by RT-PCR and Western blotting. The results showed that contractile responses of the DM rats were ameliorated after 3 weeks of TENS. Furthermore, TENS significantly increased bladder wet weight, volume threshold for micturition and reduced PVR, V% and cAMP content of the bladder. The mRNA and protein levels of CGRP in dorsal root ganglion (DRG) in the DM/TENS group were higher than those in the DM group. TENS also significantly up-regulated the cAMP content in the bladder body and base compared with diabetic rats. We conclude that TENS can significantly improve the urine contractility and ameliorate the feeling of bladder fullness in DM rats possibly via up-regulation of cAMP and CGRP in DRG.

    Gap junction (GJ) channels have been recognized as an important mechanism for synchronizing neuronal networks. Herein, we investigated the participation of GJ channels in the pilocarpine-induced status epilepticus (SE) by analyzing electrophysiological activity following the blockade of connexins (Cx)-mediated communication. In addition, we examined the regulation of gene expression, protein levels, phosphorylation profile and distribution of neuronal Cx36, Cx45 and glial Cx43 in the rat hippocampus during the acute and latent periods. Electrophysiological recordings revealed that the GJ blockade anticipates the occurrence of low voltage oscillations and promotes a marked reduction of power in all analyzed frequencies.Cx36 gene expression and protein levels remained stable in acute and latent periods, whereas upregulation of Cx45 gene expression and protein redistribution were detected in the latent period. We also observed upregulation of Cx43 mRNA levels followed by changes in the phosphorylation profile and protein accumulation. Taken together, our results indisputably revealed that GJ communication participates in the epileptiform activity induced by pilocarpine. Moreover, considering that specific Cxs undergo alterations through acute and latent periods, this study indicates that the control of GJ communication may represent a focus in reliable anti-epileptogenic strategies.

    Full Text Available The relevance of the electronics industry requires its transition to sustainable production patterns, as defined by the European directives WEEE, RoHS, and the National Policy on Solid Waste. In 2010, the group began a national project whose purpose is to support sustainability with a focus on the triple bottom line Brazilian electronics industry. The implementation of these proposals began with the implementation of a pilot project with nine companies of electromedical equipment, chosen because they are technology intensive, and require exporters suit environmental regulations. This paper aims to present the main results obtained in the studies with these nine companies in the period Apr/2011 Mar/2012 regarding the suitability of its products, processes, management systems and supply chains. The study was divided into three stages: an assessment to identify general aspects of each organization, a thorough assessment to understand the characteristics of each organization ahead of the general characteristics of the group analyzed and a detailed diagnosis, performed individually during visits in companies. The main findings were that the waste management and reverse logistics associated are still incipient, the products still have dangerous substances and supply chain is still very poorly prepared for the challenges. The level of employment of employees and costs associated with the adequacy of its products and processes, constitute the two biggest problems for companies fit the relevant environmental legislation.

    1992-12-01

    Integrated resource planning helps utilities and state regulatory commissions consistently assess a broad range of demand and supply resources to meet customer energy-service needs cost-effectively. Key characteristics of this planning approach include: explicit consideration and fair treatment of a wide variety of demand and supply options, consideration of the environmental and other social costs of providing energy services, public participation in the development of the resource plan, and analysis of the uncertainties associated with different external factors and resource options. Integrated resource planning differs from traditional planning in the types and scope of resources considered, the owners of the resources, the organizations involved in resource planning, and the criteria for resource selection. This report presents suggestions to utilities on how to conduct such planning and what to include in their resource-planning reports. These suggestions are based on a review of about 50 resource plans as well as discussions with and presentations to regulators and utilities. The suggestions cover four broad topics; the technical competence with which the plan was developed; the adequacy, detail, and consistency (with the long-term plan) of the short-term action plan; the extent to which the interests of various stakeholders was considered, both in public participation in plan development and in the variety of resource plans developedand assessed; and the clarity and comprehensiveness of the utility`s report on its plan. Technical competence includes energy and demand forecasts, assessment of supply and demand resources, resource integration, and treatment of uncertainty. Issues associated with forecasts include forecasting approaches; links between the forecasts of energy use and peak demands; and links between the forecasts and the effects of past, present, and future demand-side management programs.

  4. Development of Voltage Regulation Plan by Composing Subsystem with the SFES for DC On-line Electric Vehicle

    Science.gov (United States)

    Jung, S.; Lee, J. H.; Yoon, M.; Lee, H.; Jang, G.

    The study of the application process of the relatively small size 'Superconducting Flywheel Energy Storage (SFES)' system is conducted to regulate voltage fluctuation of the DC On-Line Electric Vehicle (OLEV) system, which is designed by using DC power system network. It is recommended to construct the power conversion system nearby the substation because the charging system is under the low voltage. But as the system is usually built around urban area and it makes hard to construct the subsystems at every station, voltage drop can occur in power supply inverter that is some distance from the substation. As the alternative of this issue, DC distribution system is recently introduced and has possibility to solve the above issue. In this paper, SFES is introduced to solve the voltage drop under the low voltage distribution system by using the concept of the proposed DC OLEV which results in building the longer distance power supply system. The simulation to design the SFES by using DC power flow analysis is carried out and it is verified in this paper.

  5. Federal regulations needing amendment to stimulate the production and introduction of electric/solar vehicles. A report to Congress, January 1990

    Energy Technology Data Exchange (ETDEWEB)

    1990-01-01

    The categories of federal regulations considered for the report were safety, emissions, and consumer protection. It was found that no current regulations act as a barrier to the introduction of electric vehicles (EVs) into commerce. The present stimulatory regulation, the Corporate Average Fuel Economy (CAFE) credit for EVs, is not sufficient to bring EVs into production, but should be maintained. The petroleum-equivalency factors in this regulation expired in 1987, but are currently being updated by the Department of Energy. There is a strong consensus among the various groups engaged in EV development and research, that automobile manufacturers retain the option to include equivalent petroleum-based fuel economy values for EVs in their CAFE (10 CFR Part 474), provided EVs are not used to determine the manufacturer's capability for purposes of establishing a fuel-economy standard. No future regulations which could be promulgated under standing legislations would be sufficient to accelerate the introduction of EVs.

  8. Learned EEG-based regulation of motor-related brain oscillations during application of transcranial electric currents: feasibility and limitations

    Directory of Open Access Journals (Sweden)

    Surjo R Soekadar

    2014-03-01

    Full Text Available Objective: Transcranial direct current stimulation (tDCS improves motor learning and can influence emotional processing or attention. However, it remained unclear whether learned electroencephalography (EEG-based brain-machine interface (BMI control during tDCS is feasible and how application of transcranial electric currents during BMI control would interfere with feature-extraction of physiological brain signals. Here we tested this combination and evaluated stimulation-dependent artifacts across different EEG frequencies and stability of motor imagery-based BMI control. Approach: Ten healthy volunteers were invited to two BMI-sessions, each comprising two 60-trial blocks. During the trials, modulation of mu-rhythms (8-15Hz associated with motor imagery recorded over C4 was translated into online cursor movements on a computer screen. During block 2, either sham (session A or anodal tDCS (session B was applied at 1mA with the stimulation electrode placed 1cm anterior of C4. Main results: tDCS was associated with a significant signal power increase in the lower frequencies most evident in the signal spectrum of the EEG channel closest to the stimulation electrode. Stimulation-dependent signal power increase exhibited a decay of 12dB per decade, leaving frequencies above 9Hz unaffected. Analysis of BMI control performance did not indicate a difference between blocks and tDCS conditions. Conclusion: Application of tDCS during learned EEG-based self-regulation of brain oscillations above 9Hz is feasible and safe, and might improve applicability of BMI systems in patient populations.

  12. Electric fields generated by synchronized oscillations of microtubules, centrosomes and chromosomes regulate the dynamics of mitosis and meiosis

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available Abstract Super-macromolecular complexes play many important roles in eukaryotic cells. Classical structural biological studies focus on their complicated molecular structures, physical interactions and biochemical modifications. Recent advances concerning intracellular electric fields generated by cell organelles and super-macromolecular complexes shed new light on the mechanisms that govern the dynamics of mitosis and meiosis. In this review we synthesize this knowledge to provide an integrated theoretical model of these cellular events. We suggest that the electric fields generated by synchronized oscillation of microtubules, centrosomes, and chromatin fibers facilitate several events during mitosis and meiosis, including centrosome trafficking, chromosome congression in mitosis and synapsis between homologous chromosomes in meiosis. These intracellular electric fields are generated under energy excitation through the synchronized electric oscillations of the dipolar structures of microtubules, centrosomes and chromosomes, three of the super-macromolecular complexes within an animal cell.

    Full Text Available El artículo analiza la evolución de la regulación del sector eléctrico en Argentina y Brasil entre 1890 y 1960. Desde la instalación de las primeras usinas eléctricas a fines del siglo diecinueve hasta los años treinta, el control de las empresas concesionarias estuvo a cargo de las autoridades municipales en ambos países. No obstante, la similar estructura de los sistemas eléctricos en Argentina y en Brasil, la participación del estado en la regulación de este sector estratégico para el desarrollo económico, se produjo en diferentes coyunturas. Como resultado de la crisis de 1930, el gobierno brasileño transformó los principios jurídicos que reglamentaban la gestión de la electricidad aplicando un criterio de regulación discrecional; mientras que el estado argentino intervino una década más tarde, nacionalizando las empresas. Mediante la comparación de las trayectorias regulatorias en ambos países, se identifican las divergencias en las políticas eléctricas y su impacto en los sistemas eléctricos en los años de la segunda posguerra.This article compares the evolution of electric utility regulation in Argentina and Brazil between 1890 and 1960. From the installation of electrical systems in the 19th century until the 1930s, electrical utility companies were controlled by the local authorities in both countries. The structure of electrical systems was similar in Argentina and Brazil, however the state regulation of electric utilities took place at different times. As a result of the 1930's crisis, the Brazilian government introduced a new legal approach by applying a discretionary regulation. On the other hand, the Argentinean government intervened one decade later, nationalizing the companies. By comparing both regulatory trajectories, the divergences as well as the effects of each policy on the electrical utility systems in the second postward period, are identified.

  20. Constructing nanoporous carbon nanotubes/Bi2Te3 composite for synchronous regulation of the electrical and thermal performances

    Porous nanograined thermoelectric materials exhibit low thermal conductivity due to scattering of phonons by pores, which are favorable for thermoelectric applications. However, the benefit is not large enough to overcome the deficiency in the electrical performance. Herein, an approach is presented to reduce the thermal conductivity and synchronously enhance the electrical conductivity through constructing a nanoporous thermoelectric composite. Carbon nanotubes (CNTs) are truncated and homogeneously dispersed within the Bi2Te3 matrix by a cryogenic grinding (CG) technique for the first time, which efficiently suppress the Bi2Te3 grain growth and create nanopores with the size ranging from dozens to hundreds of nanometers. The lattice thermal conductivity is substantially decreased by broad wavelength phonon scattering resulting from nanopores, increased grain boundaries, and newly formed interfaces. Meanwhile, the electrical conductivity is improved due to the enhanced carrier mobility, which may originate from the bridging effect between the Bi2Te3 grains and CNTs. The maximum ZT is improved by almost a factor of 2 due to the simultaneous optimization of electrical and thermal performances. Our study demonstrates the superiority of constructing a bulk thermoelectric composite with nanopores by the uniform dispersion of CNTs through a CG technique for enhanced thermoelectric properties, which provides a wider approach to thermoelectric nanostructure engineering.

    Leck, Kira

    2006-10-01

    Researchers have associated minimal dating with numerous factors. The present author tested shyness, introversion, physical attractiveness, performance evaluation, anxiety, social skill, social self-esteem, and loneliness to determine the nature of their relationships with 2 measures of self-reported minimal dating in a sample of 175 college students. For women, shyness, introversion, physical attractiveness, self-rated anxiety, social self-esteem, and loneliness correlated with 1 or both measures of minimal dating. For men, physical attractiveness, observer-rated social skill, social self-esteem, and loneliness correlated with 1 or both measures of minimal dating. The patterns of relationships were not identical for the 2 indicators of minimal dating, indicating the possibility that minimal dating is not a single construct as researchers previously believed. The present author discussed implications and suggestions for future researchers.

    Scientists involved in ice core dating are well familiar with the problem of identification and recording the depth of annual signals using stable isotopes, glaciochemistry, ECM (electrical conductivity), DEP (dielectric properties) and particle counter data. Traditionally all parameters used for ice core dating were plotted as a function of depth, printed and after years were marked on the paper, converted to depth vs. age time scale. To expedite this tedious and manual process we developed interactive computer software, Ice core Dating (ICD) program. ICD is written in Java programming language, and uses GPL and GPL site licensed graphic libraries. The same 3.5 Mb in size pre-compiled single jar file, that includes all libraries and application code, was successfully tested on WinOS, Mac OSX, Linux, and Solaris operating systems running Java VM version 1.4. We have followed the modular design philosophy in our source code so potential integration with other software modules, data bases and server side distributed computer environments can be easily implemented. We expect to continue development of new suites of tools for easy integration of ice core data with other available time proxies. ICD is thoroughly documented and comes with a technical reference and cookbook that explains the purpose of the software and its many features, and provides examples to help new users quickly become familiar with the operation and philosophy of the software. ICD is available as a free download from the Climate Change Institute web site ( under the terms of GNU GPL public license.

    Souza, Fabio Cavaliere de

    2008-11-15

    This thesis analyses the dynamics of risk management in the regulated contracting environment of the Brazilian electrical sector. As in the new model the distribution utilities are obliged to ensure energy contracting to supply their whole markets, these companies became exposed to volume risks related to the demand uncertainties. So the new model following similar directives from the first phase developed management tools to mitigate the new risks mentioned above. As in a well structured market it is expected that the risks should be evenly shared or that risk management tools should be provided for all, this work intended to analyze the dynamics of the designed mechanisms and their impacts over the regulated market. In this work the risks of the electricity markets are studied and the management tools devised for the Brazilian market are identified. Finally for understanding the dynamics a thorough analysis of the auctions, of the mechanism for compensation of surplus and deficits and tariffs are carried on. The results show that the management tools were regularly employed by distribution companies, but the risks were merely transferred to the captive customers leading to distortions and asymmetries that conflict with the basis that guided the second phase of the reform. The work proposes remedial actions to mitigate the observed impacts and to provide risk management tools to the captive customer. (author)

    The European Energy Policy promotes renewable energy sources and energy efficiency as means to mitigate environmental impact, increase security of supply and ensure economic competitiveness. As a result, the penetration levels of distributed generation (DG) in electricity networks are bound to increase. Distribution networks and distribution system operators (DSOs) will be especially affected by growing levels of DG. This paper reviews the current regulation of distribution in the European Union Member States, focusing on those aspects that might hinder the future integration of DG. Several regulatory issues that may hinder a successful integration of DG have been identified. Recommendations to improve the current situation are proposed. Regarding economic signals sent to DG, connection charges and cost-reflective use-of-system charges together with incentives to provide ancillary services are the key aspects. Concerning DSOs regulation, unbundling from generation and supply according to the European Electricity Directive, incentives for optimal planning and network operation considering DG, including energy losses and quality of service, and innovation schemes to migrate to active networks are the most relevant topics.

    The decision to introduce competition into regulated industries is a key issue in economics. Provided that the demand is sufficiently inelastic, competition assures lower allocative distortions at the cost of weaker cost-reducing investment incentives via lower profits. Hence, deregulation is more

    Innovative photoresponsive materials are needed to address the complexity of optical control systems. Here, we report a new type of photoresponsive nanomaterial composed of graphene and a form-stable phase change material (PCM) that exhibited a 3 orders of magnitude change in electrical resistivity upon light illumination while retaining its overall original solid form at the macroscopic level. This dramatic change in electrical resistivity also occurred reversibly through the on/off control of light illumination. This was attributed to the reversible phase transition (i.e., melting/recrystallization) behavior of the microscopic crystalline domains present in the form-stable PCM. The reversible phase transition observed in the graphene/PCM nanocomposite was induced by a reversible temperature change through the on/off control of light illumination because graphene can effectively absorb light energy and convert it to thermal energy. In addition, this graphene/PCM nanocomposite also possessed excellent mechanical properties. Such photoresponsive materials have many potential applications, including flexible electronics.

    Activation of extracellular signal-regulated kinase-1/2 (ERK1/2) and its involvement in regulating gene expression in spinal dorsal horn, cortical and subcortical neurons by peripheral noxious stimulation contribute to pain hypersensitivity. Transcutaneous electrical nerve stimulation (TENS) is a treatment used in physiotherapy practice to promote analgesia in acute and chronic inflammatory conditions. In this study, a total number of 114 rats were used for three experiments. Effects of complete Freund's adjuvant (CFA)-induced inflammatory pain hypersensitivity and TENS analgesia on ERK1/2 phosphorylation and c-Fos protein expression were examined by using behavioral test, Western blot, and immunostaining methods. We found that CFA injection caused an area of localized swelling, erythema, hypersensitivity to thermal stimuli, the decreased response time of hind paw licking (HPL), as well as upregulation of c-Fos protein expression and ERK2 phosphorylation in the ipsilateral spinal dorsal horn and the contralateral primary somatosensory area of cortex and the amygdala of rats. TENS on Yongquan acupoint for 20 min produced obvious analgesic effects as demonstrated with increased HPL to thermal stimuli of CFA-treated rats. In addition, TENS application suppressed the CFA-induced ERK2 activation and c-Fos protein expression. These results suggest that down-regulation of ERK2 phosphorylation and c-Fos expression were involved in TENS inhibition on CFA-induced thermal hyperalgesia of rats.

    An efficient-price mechanism for electricity transmission is very hard to find, essentially because of the natural monopoly condition of the grid and its peculiar interactions with generation. The use of Optimal Power Flow Models is difficult to implement and could be easily distorted by strategical behaviour of generators. These models, however, could became a valuable efficiency-test for actual transmission charges and codes. [Italiano] Il prezzo efficiente della trasmissione di energia elettrica e` molto difficile da determinare, sia per le condizioni di monopolio naturale, sia per le strette interazioni con la generazione. I modelli di ottimizzazione che cercano di rappresentare queste interazioni, d`altra parte, non sono semplici da implementare e potrebbero indurre comportamenti strategici, ma possono diventare un utile strumento per giudicare le effettive modalita` tecniche ed economiche di accesso alla rete di trasmissione.

    Full Text Available The authors present the experimental performance of the heat of wetting depending on the number of functional groups on the surface of quartz sand. It is established that in the process of increase of specific surface of fine ground quartz filler naturally there is an increase in the total number of active centers, but their number does not change per unit of surface. The calorimetric method of analysis established that the mechanical activation increases the reactivity centers. This is the result of chemical reactions occurring on the surface, for example, under the influence of water present in the air. The authors observed hydration of surface groups and change in their reactivity. A method of regulation of rheological characteristics of pastes with plasticizing additives in the system ”cement - quartz sand - graphite“ was developed, which was aimed to reduce the ultimate shear stress up to 0.5...1.3 PA and water-composite relationship of a sand mix by 15...25 % while maintaining the viscosity of the paste that provides a uniform application of the composite in screed floors technology possessing electrical conductivity. Polycarboxylate is an efficient plasticizing additive which maintains self-levelling effect of the mixture at optimum water-cement ratio. It was determined that the threshold concentration of electrical current flow in the studied system is 0.15 (wt., at which the aggregation of contacting graphite particles with the formation of a continuous three-dimensional mesh a conducting current is observed in the structure of the composite. The change in the concentration of the graphite allows ensuring the stability of the electrophysical parameters of the resistive materials and structures based on them. In order to increase the electrical conductivity of graphite dispersions in a model system a plasticizer was added, which reduces water-composite ratio in the formation of pastes. Chemical-based plasticizer has no significant

    Full text: Opal phytoliths are microscopic silica bodies formed by the precipitation of hydrated silica dioxide (SiO{sub 2}nH{sub 2}0) in, around and between cell walls. They are relatively resistant to degradation in most environments and thus, can occur in large quantities in palaeosediments. Consequently, they are valuable tools for environmental reconstruction. Furthermore, phytoliths are often the only recoverable organic material in well oxidised sediments, the occluded carbon provides the opportunity for dating sediment whose ages have previously been difficult to determine, and thus, increase the potential for fine resolution determination of environmental change. This poster describes the results of an investigation assessing the viability of AMS radiocarbon dating of fossil phytolith inclusions using samples from Garua Island, West New Britain, PNG. Thirteen phytolith samples, isolated from sediments previously dated using tephrastratigraphy and C14 dating of macroremains of nutshells and wood charcoal, were used in the analysis. As a control measure, thirteen parallel samples of microscopic charcoal were also dated using AMS. The results show that the AMS dates for the microscopic charcoal samples are consistent with ages anticipated from the other dating methods, for all but one sample. However, the dates for eight of the thirteen phytolith samples are considerably younger than expected. This bias could be explained by several factors, including downwashing of phytolith through soils, bioturbation, carbon exchange through the siliceous matrix of the phytolith bodies, and contamination from extraneous sources of modern carbon retained in the samples. Research is currently focusing on the investigation of these issues and selected samples are in the process of being retreated with strong oxidising agents to clear contaminants prior to re-dating. Further to this, a full investigation of one profile with a long sequence is underway. High concentrations of

  11. A Bi-Level Optimization Approach to Charging Load Regulation of Electric Vehicle Fast Charging Stations Based on a Battery Energy Storage System

    Directory of Open Access Journals (Sweden)

    Yan Bao

    2018-01-01

    Full Text Available Fast charging stations enable the high-powered rapid recharging of electric vehicles. However, these stations also face challenges due to power fluctuations, high peak loads, and low load factors, affecting the reliable and economic operation of charging stations and distribution networks. This paper introduces a battery energy storage system (BESS for charging load control, which is a more user-friendly approach and is more robust to perturbations. With the goals of peak-shaving, total electricity cost reduction, and minimization of variation in the state-of-charge (SOC range, a BESS-based bi-level optimization strategy for the charging load regulation of fast charging stations is proposed in this paper. At the first level, a day-ahead optimization strategy generates the optimal planned load curve and the deviation band to be used as a reference for ensuring multiple control objectives through linear programming, and even for avoiding control failure caused by insufficient BESS energy. Based on this day-ahead optimal plan, at a second level, real-time rolling optimization converts the control process to a multistage decision-making problem. The predictive control-based real-time rolling optimization strategy in the proposed model was used to achieve the above control objectives and maintain battery life. Finally, through a horizontal comparison of two control approaches in each case study, and a longitudinal comparison of the control robustness against different degrees of load disturbances in three cases, the results indicated that the proposed control strategy was able to significantly improve the charging load characteristics, even with large disturbances. Meanwhile, the proposed approach ensures the least amount of variation in the range of battery SOC and reduces the total electricity cost, which will be of a considerable benefit to station operators.

  20. Solvent Role in the Formation of Electric Double Layers with Surface Charge Regulation: A Bystander or a Key Participant?

    2016-01-01

    The charge formation at interfaces involving electrolyte solutions is due to the chemical equilibrium between the surface reactive groups and the potential determining ions in the solution (i.e., charge regulation). In this Letter we report our findings that this equilibrium is strongly coupled to the precise molecular structure of the solution near the charged interface. The neutral solvent molecules dominate this structure due to their overwhelmingly large number. Treating the solvent as a structureless continuum leads to a fundamentally inadequate physical picture of charged interfaces. We show that a proper account of the solvent effect leads to an unexpected and complex system behavior that is affected by the molecular and ionic excluded volumes and van der Waals interactions.

    A new, high-energy-efficiency charging operation with as little amount of overcharge as possible is proposed to improve the energy efficiency and the cycle life for an EV valve-regulated lead-acid battery. Under this operation, the EV battery system is charged with 105% of amount of the preceding discharge five out of six times and once with 115% in order that it is fully charged. The cycle lives were estimated using a valve-regulated lead-acid battery system of 12 modules connected in series, by SFUDS79 pattern discharging and measurement of the amount of discharge every 50 cycles. Three-step constant current charging with 115% of amount of the preceding discharge required more than 5 h with the final charging step of more than 210 min, with coulomb efficiency of only 87% and energy efficiency of 74%. On the other hand, under the high-energy-efficiency charging operation, three-step charging with 105% shortens the final charging time to 132 min. It was completed in less than 4 h with coulomb and energy efficiency of 95% and 84%, respectively. This operation increased the energy efficiency from 74% to 83% on average in six charging, and extended the cycle life by about 30% to more than 400 cycles. Decreasing the amount of charge by as much as possible suppressed the corrosion of the grids in the positive plate and the heat evolution in batteries due to shortening of the final charging step. Although the high-energy-efficiency charging operation led to the accumulation of inactive PbSO{sub 4} at the upper part of the negative plate, possibly due to the decreasing amount of overcharge, this operation could prolong the cycle life. Full charging once every six times is though to be effective in suppressing degradation caused by the accumulation of inactive PbSO{sub 4} in the negative plate due to the shortage of charge.

    What is the central question of this study? The aim was to investigate the roles of extracellular chloride in electrical slow waves and resting membrane potential of mouse jejunal smooth muscle by replacing chloride with the impermeant anions gluconate and isethionate. What is the main finding and its importance? The main finding was that in smooth muscle cells, the resting Cl - conductance is low, whereas transmembrane Cl - movement in interstitial cells of Cajal (ICCs) is a major contributor to the shape of electrical slow waves. Furthermore, the data confirm that ICCs set the smooth muscle membrane potential and that altering Cl - homeostasis in ICCs can alter the smooth muscle membrane potential. Intracellular Cl - homeostasis is regulated by anion-permeable channels and transporters and contributes to excitability of many cell types, including smooth muscle and interstitial cells of Cajal (ICCs). Our aims were to investigate the effects on electrical activity in mouse jejunal muscle strips of replacing extracellular Cl - (Cl - o ) with the impermeant anions gluconate and isethionate. On reducing Cl - o , effects were observed on electrical slow waves, with small effects on smooth muscle membrane voltage (E m ). Restoration of Cl - hyperpolarized smooth muscle E m proportional to the change in Cl - o concentration. Replacement of 90% of Cl - o with gluconate reversibly abolished slow waves in five of nine preparations. Slow waves were maintained in isethionate. Gluconate and isethionate substitution had similar concentration-dependent effects on peak amplitude, frequency, width at half peak amplitude, rise time and decay time of residual slow waves. Gluconate reduced free ionized Ca 2+ in Krebs solutions to 0.13 mm. In Krebs solutions containing normal Cl - and 0.13 mm free Ca 2+ , slow wave frequency was lower, width at half peak amplitude was smaller, and decay time was faster. The transient hyperpolarization following restoration of Cl - o was not observed

    Aim: To document the timing of the appearance of the radiological features of fracture healing in a group of infants in which the date of injury was known and to assess the degree of interobserver agreement. Materials and methods: Three paediatric radiologists independently assessed 161 images of 37 long bone fractures in 31 patients aged 0-44 months. The following features were assessed: soft-tissue swelling, subperiosteal new bone formation (SPNBF), definition of fracture line, presence or absence of callus, whether callus was well or ill defined, and the presence of endosteal callus. Results: Agreement between observers was only moderate for all discriminators except SPNBF. SPNBF was invariably seen after 11 days but was uncommon before this time even in the very young. In one case SPNBF was seen at 4 days. Conclusion: With the exception of SPNBF, the criteria relied on to date fractures are either not reproducible or are poor discriminators of fracture age.

    The development of wholesale electricity prices showed in recent years a very fluctuating course. The starting point for ensuring competitive compliant electricity prices have uniform rules that establish effective competition in the overall wholesale electricity, ensure greater transparency in the market and prohibit market abuse influence exercised on the wholesale price. The REMIT regulation creates a first union-law rules to this standardized specifications. The volume first examines the transparency, competitiveness, and supervisory structures in the wholesale electricity before legislating a regulation. It is clear, as the transparency and supervisory structures should be designed from the wholesale electricity ideally. On this basis, the work is dealing with the REMIT regulation. The author works out to market participants relevant notification and publication requirements, the follow-up demands on the company as well as the now existing prohibitions on market abuse and the related penalty catalog and analyze the supervisory structures newly created in the wholesale electricity. Here, the work also identified the weaknesses of the regulation and shows suitable solution approaches. [German] Die Entwicklung der Stromgrosshandelspreise zeigte in den letzten Jahren einen sehr schwankenden Verlauf. Ausgangspunkt fuer die Gewaehrleistung wettbewerbskonformer Strompreise sind einheitliche Bestimmungen, die im gesamten Stromgrosshandel einen funktionierenden Wettbewerb etablieren, fuer mehr Transparenz am Markt sorgen und marktmissbraeuchliche Einflussnahmen auf den Grosshandelspreis verbieten.

  13. Application of valve-regulated lead-acid batteries for storage of solar electricity in stand-alone photovoltaic systems in the northwest areas of China

    Science.gov (United States)

    Hua, Shounan; Zhou, Qingshen; Kong, Delong; Ma, Jianping

    Photovoltaic (PV) installations for solar electric power generation are being established rapidly in the northwest areas of China, and it is increasingly important for these power systems to have reliable and cost effective energy storage. The lead-acid battery is the more commonly used storage technology for PV systems due to its low cost and its wide availability. However, analysis shows that it is the weakest component of PV power systems. Because the batteries can be over discharged, or operated under partial state of charge (PSOC), their service life in PV systems is shorter than could be expected. The working conditions of batteries in remote area installations are worse than those in situations where technical support is readily available. Capacity-loss in lead-acid batteries operated in remote locations often occurs through sulfation of electrodes and stratification of electrolyte. In northwest China, Shandong Sacred Sun Power Sources Industry Co. Ltd. type GFMU valve-regulated lead-acid (VRLA) batteries are being used in PV power stations. These batteries have an advanced grid structure, superior leady paste, and are manufactured using improved plate formation methods. Their characteristics, and their performance in PV systems, are discussed in this paper. The testing results of GFMU VRLA batteries in the laboratory have shown that the batteries could satisfy the demands of the International Electrotechnical Commission (IEC) standards for PV systems.

  14. Control Performance of General Electric Fuel and Torque Regulator Operating on T31-3 Turbine-Propeller Engine in Sea-Level Test Stand

    Oppenheimer, Frank L.; Lazar, James

    1951-01-01

    A .General Electric fuel and torque regulator was tested in conjunction with a T31-3 turbine-propeller engine in the sea-level static test stand at the NACA Lewis laboratory. The engine and control were operated over the entire speed range: 11,000 rpm, nominal flight idle, to 13,000 rpm, full power. Steady-state and transient data were recorded and are presented with a description of the four control loops being used in the system. Results of this investigation indicated that single-lever control operation was satisfactory under conditions of test. Transient data presented showed that turbine-outlet temperature did overshoot maximum operating value on acceleration but that the time duration of overshoot did not exceed approximately 1 second. This temperature limiting resulted from a control on fuel flow as a function of engine speed. Speed and torque first reached their desired values 0.4 second from the time of change in power-setting lever position. Maximum speed overshoot was 3 percent.

  15. 210Pb dating

    Swarzenski, Peter W.

    2014-01-01

    Roughly fifty years ago, a small group of scientists from Belgium and the United States, trying to better constrain ice sheet accumulation rates, attempted to apply what was then know about environmental lead as a potential geochronometer. Thus Goldberg (1963) developed the first principles of the 210Pb dating method, which was soon followed by a paper by Crozaz et al. (1964), who examined accumulation history of Antarctic snow using 210Pb. Shortly thereafter, Koide et al. (1972, 1973) adapted this technique to unravel sediment deposition and accumulation records in deep-sea environments. Serendipitously, they chose to work in a deep basin off California, where an independent and robust age model had already been developed. Krishanswami et al. (1971) extended the use of this technique to lacustrine deposits to reconstruct depositional histories of lake sediment, and maybe more importantly, contaminant inputs and burial. Thus, the powerful tool for dating recent (up to about one century old) sediment deposits was established and soon widely adopted. Today almost all oceanographic or limnologic studies that address recent depositional reconstructions employ 210Pb as one of several possible geochronometers (Andrews et al., 2009; Gale, 2009; Baskaran, 2011; Persson and Helms, 2011). This paper presents a short overview of the principles of 210Pb dating and provides a few examples that illustrate the utility of this tracer in contrasting depositional systems. Potential caveats and uncertainties (Appleby et al., 1986; Binford, 1990; Binford et al., 1993; Smith, 2001; Hancock et al., 2002) inherent to the use and interpretation of 210Pb-derived age-models are also introduced. Recommendations as to best practices for most reliable uses and reporting are presented in the summary.

    We consider whether the long term perturbation of radiocarbon dates, which is known to be approximately a sin function of period about 8000 years and amplitude of about 8% peak-to-peak, could have been caused in any major part by vulcanism. We conclude that this is not the case. On the contrary, present day volcanoes are a far less important source of inert CO{sub 2} (about 100 fold less) than is man's burning of fossil fuels which has caused the Suess dilution of about 2%.

    1998-01-01

    Increased competition in bulk power and retail electricity markets is likely to lower electricity prices, but will also result in greater price volatility as the industry moves away from administratively determined, cost-based rates and encourages market-driven prices. Price volatility introduces new risks for generators, consumers, and marketers. Electricity futures and other derivatives can help each of these market participants manage, or hedge, price risks in a competitive electricity market. Futures contracts are legally binding and negotiable contracts that call for the future delivery of a commodity. In most cases, physical delivery does not take place, and the futures contract is closed by buying or selling a futures contract on or near the delivery date. Other electric rate derivatives include options, price swaps, basis swaps, and forward contracts. This report is intended as a primer for public utility commissioners and their staff on futures and other financial instruments used to manage price risks. The report also explores some of the difficult choices facing regulators as they attempt to develop policies in this area.

    Due to its simple production and transport processes in the terrestrial environment, the long-lived noble-gas isotope 81Kr (half-life = 230 kyr) is the ideal tracer for studying old water and ice in the age range of 10^5-10^6 years, a range beyond the reach of 14C. 81Kr dating, a concept pursued in the past four decades by numerous laboratories employing a variety of techniques, is now available for the first time to the earth science community at large. This is made possible by the development of ATTA-3 (Jiang et al., GCA 91, 1-6; 2012), an efficient and selective atom counter based on the Atom Trap Trace Analysis method (Chen et al., Science 286, 1139-1141; 1999). The instrument is capable of measuring both 81Kr/Kr and 85Kr/Kr ratios of environmental samples in the range of 10^-14-10^-10. For 81Kr-dating in the age range of 150 - 1,500 kyr, the required sample size is 5 - 10 micro-L STP of krypton gas, which can be extracted from approximately 100 - 200 kg of water or 40 - 80 kg of ice. For 85Kr/Kr analysis, the required sample size is generally smaller by an order of magnitude because of the isotope's higher initial abundance in the atmosphere. The Laboratory for Radiokrypton Dating is currently equipped to analyze up to 120 samples per year. With future equipment upgrades, this limit can be increased as demand grows. In the period since November 2011, the Laboratory has measured both 81Kr/Kr and 85Kr/Kr ratios in over 50 samples that had been extracted by collaborators from six different continents. The samples were from groundwater wells in the Great Artesian Basin (Australia), Guarani Aquifer (Brazil), and Locust Grove (Maryland); from brine wells of the Waste Isolation Pilot Plant (New Mexico); from geothermal steam vents in Yellowstone National Park; from near-surface ice at Taylor Glacier, Antarctica; and from deep mines in South Africa.

    For the popularization of electric vehicles (EVs), the conditions for charging EV batteries with available current patterns should allow complete charging in a short time, i.e., less than 5 to 8 h. Therefore, in this study, a new charging condition is investigated for the EV valve-regulated lead/acid battery system, which should allow complete charging of EV battery systems with multi-step constant currents in a much shorter time with longer cycle life and higher energy efficiency compared with two-step constant-current charging. Although a high magnitude of the first current in the two-step constant-current method prolongs cycle life by suppressing the softening of positive active material, too large a charging current magnitude degrades cells due to excess internal evolution of heat. A charging current magnitude of approximately 0.5 C is expected to prolong cycle life further. Three-step charging could also increase the magnitude of charging current in the first step without shortening cycle life. Four-or six-step constant-current methods could shorten the charging time to less than 5 h, as well as yield higher energy efficiency and enhanced cycle life of over 400 cycles compared with two-step charging with the first step current of 0.5 C. Investigation of the degradation mechanism of the batteries revealed that the conditions of multi-step constant-current charging suppressed softening of positive active material and sulfation of negative active material, but, unfortunately, advanced the corrosion of the grids in the positive plates. By adopting improved grids and cooling of the battery system, the multistep constant-current method may enhance the cycle life. (orig.)

    2007-12-01

    The current study examined the joint contributions of pubertal maturation, parental monitoring, involvement in older peer groups, peer dating, and peer delinquency on dating in a sample of early adolescent boys and girls. The sample consisted of 784 adolescents (394 boys, 390 girls) enrolled in grades 5, 6, and 7 who were followed for one year. In addition to measures of pubertal maturation and parental monitoring, adolescents and their peer group members completed indices of dating and delinquency. Average dating and delinquency scores for each participant's peer group network were computed. Results indicated that it was the combination of pubertal maturation, peer delinquency, and peer dating that explained increases in early dating. For boys only, parental monitoring was a significant predictor. The more knowledgeable parents were about their boys' activities, the lower the number of dating activities reported. These results highlight the importance of considering the joint effects of these biological and social predictors in understanding early dating. When rapid changes occur in all three domains, early dating is most likely to ensue. The findings of this study have practical importance. Parents and professionals who work closely with youth should attend to the special vulnerability of early maturing adolescents in the face of peer pressure and to the important role of parental monitoring in regulating dating activities.

    In this paper, radiocarbon dating of paintings using minimal sample sizes has been investigated, in an effort to address the problem of limited access to sample material in paintings. {sup 14}C analyses were conducted on signed and dated paintings from two Swiss artists of the twentieth century. The selected paintings dated from the 1930s and 1960s, provided the opportunity to evaluate the dating accuracy on paintings realized before and after 1950 AD when the {sup 14}C bomb peak was created, as a result of the nuclear tests conducted in the 1950/1960s. The work focused on the one hand on minimizing the size of the canvas sample required for accelerator mass spectrometer radiocarbon measurement on the gas ion source of the MICADAS and, on the other hand, on testing the possibility of dating the organic binder of the paint. Following careful characterization of the paint composition by X-ray fluorescence spectroscopy, Fourier transformed infrared spectroscopy, and Raman spectroscopy, paints containing no other carbon source than the natural organic binder were identified and dated.

  17. Radiocarbon dating of iron artefacts

    Energy Technology Data Exchange (ETDEWEB)

    Cresswell, R. [Australian National Univ., Canberra, ACT (Australia). Dept. of Nuclear Physics

    1997-12-31

    Iron artefacts are generally dated by association or on stylistic grounds. This may not give a true indication of the date of manufacture, or may not be possible if the piece is out of context, ambiguous in style, or a copy. Obtaining a direct date on the artefact would be preferable. During the processes of manufacture, carbon is incorporated into the iron from the fuel source. If the fuel is of a material containing contemporaneous carbon, i.e. has an ambient radiocarbon signature, e.g. charcoal, then we may reliably radiocarbon date the artefact by extracting this carbon. Care must be taken, however, to ensure that re-working has not introduced multiple sources of carbon that would give an erroneous date. Detailed chemical analysis must precede radiocarbon analysis. Sample size is determined by carbon content, and before the advent of accelerator mass spectrometry, several tens of grams of carbon were required for radiocarbon dating (van der Merwe, 1969), prohibiting this method except for high-carbon cast-irons and bulk samples, e.g. caches of nails. AMS permits the analysis of sub-gram pieces of iron (Cresswell, 1991), thereby permitting the analysis of museum pieces with only minimal loss of material, and small fragments of iron recovered from archaeological sites. A few examples are given to illustrate these points. Paper no. 41; Extended abstract. 6 refs.

    This report first presents the French regulated price system by recalling the legal bases for electricity and natural gas pricing, and by describing the progressive process of the electricity and natural gas market opening in France. It outlines that a reversibility principle has been introduced along with regulated pricing in most of the European Union countries. It also comments the complexity created on this issue by successive laws in France, the consequences of the soon coming law on the new organization of the electricity market. Then, the report comments the proposition which aims at authorizing electricity household users and small companies to go back to the regulated electricity price, thereby perpetuating the reversibility principle, while maintaining a criterion of installed electricity power, including natural gas prices and new consumption sites. A table proposes a comparison between existing texts, the present law project and this Commission proposition.

    This research sought to address the relationship between self-concept and customer satisfaction: can customer satisfaction with a major electric utility be explained in terms of the self-reported, self-concept of the utility's managers The population to which the results of this study were generalized consisted of customer service managers in public electric utilities across the United States. In order to represent this population, a sample was selected consisting of customer service managers at a midwestern electric utility based in a large metropolitan area. Participants in this study were managers of four direct customer contact service organizations within six geographic division organizations. The methodology included comparisons of these four customer contact service organizations on twelve independent, self-concept variables and six customer satisfaction dependent variables using Analysis of Variance (ANOVA), Scheffe' tests, Chi-Square, and Stepwise multiple regression. The groups were found not to be significantly different and knowledge of the self-concept scores for managers will not increase the ability to predict customer satisfaction over no knowledge of self-concept scores.

  10. ESR dating of fault rocks

    Lee, Hee Kwon [Kangwon National Univ., Chuncheon (Korea, Republic of)

    2002-03-15

    Past movement on faults can be dated by measurement of the intensity of ESR signals in quartz. These signals are reset by local lattice deformation and local frictional heating on grain contacts at the time of fault movement. The ESR signals then trow back as a result of bombardment by ionizing radiation from surrounding rocks. The age is obtained from the ratio of the equivalent dose, needed to produce the observed signal, to the dose rate. Fine grains are more completely reset during faulting, and a plot of age vs grain size shows a plateau for grains below critical size : these grains are presumed to have been completely zeroed by the last fault activity. We carried out ESR dating of fault rocks collected from the Yangsan fault system. ESR dates from the this fault system range from 870 to 240 ka. Results of this research suggest that long-term cyclic fault activity continued into the pleistocene.

    Highlights: • The work links the surface morphology of amorphous semiconductors with both their electric-thermal properties and current stability at the nanoscale (<1 μm). • Measured high correlation value between surface morphological spatial gradient and conductive electron energy spatial gradient or thermal gradient. • Unidirectional current stability is associated with asymmetric nanodomains along nanosize conductive paths. • Bidirectional current stability is inherent with either long conductive paths or nanosize conductive paths along symmetric nanodomains. • Conclusion: Surface design improves current stability across nanoelectonic junctions. - Abstract: A link between the morphological characteristics and the electric properties of amorphous layers is established by means of atomic, conductive, electrostatic force and thermal scanning microscopy. Using amorphous Ta{sub 2}O{sub 5} (a-Ta{sub 2}O{sub 5}) semiconductive layer, it is found that surface profile gradients (morphological gradient), are highly correlated to both the electron energy gradient of trapped electrons in interactive Coulombic sites and the thermal gradient along conductive paths and thus thermal and electric properties are correlated with surface morphology at the nanoscale. Furthermore, morphological and electron energy gradients along opposite conductive paths of electrons intrinsically impose a current stability anisotropy. For either long conductive paths (L > 1 μm) or along symmetric nanodomains, current stability for both positive and negative currents i is demonstrated. On the contrary, for short conductive paths along non-symmetric nanodomains, the set of independent variables (L, i) is spanned by two current stability/intability loci. One locus specifies a stable state for negative currents, while the other locus also describes a stable state for positive currents.

    For the waiting world, and indeed for most of us here at CERN, ‘the LHC schedule’ simply means the date that the LHC will restart - and we only take notice when that end-date changes. But in fact the schedule is a constantly evolving intricate document coordinating all the repairs, consolidation and commissioning in every part of the machine. So, what actually goes on behind the scenes in timing and planning all the work on one of the most complex scientific instruments ever built?

    An efficiency improvement parameter is an integrated part of a family of regulatory mechanisms often denoted as RPI-X. The present report examines what factors are to be included in the efficiency improvement factor. A theoretical derivation shows that the income growth in the regulated sector shall be limited to the price growth of the economy corrected for a factor-X that consists of four components: a productivity component, a price component, a component that accounts for differences in exogenic costs in the regulated sector and the rest of the economy, and a activity level component. The productivity component accounts for the differences in productivity changes between the two sectors, and the price component accounts for the differences in the prices of factor inputs.

    We explored the use of continuous waterborne electrical imaging (CWEI), in conjunction with fiber-optic distributed temperature sensor (FO-DTS) monitoring, to improve the conceptual model for uranium transport within the Columbia River corridor at the Hanford 300 Area, Washington. We first inverted resistivity and induced polarization CWEI data sets for distributions of electrical resistivity and polarizability, from which the spatial complexity of the primary hydrogeologic units was reconstructed. Variations in the depth to the interface between the overlying coarse-grained, high-permeability Hanford Formation and the underlying finer-grained, less permeable Ringold Formation, an important contact that limits vertical migration of contaminants, were resolved along ˜3 km of the river corridor centered on the 300 Area. Polarizability images were translated into lithologic images using established relationships between polarizability and surface area normalized to pore volume (Spor). The FO-DTS data recorded along 1.5 km of cable with a 1 m spatial resolution and 5 min sampling interval revealed subreaches showing (1) temperature anomalies (relatively warm in winter and cool in summer) and (2) a strong correlation between temperature and river stage (negative in winter and positive in summer), both indicative of reaches of enhanced surface water-groundwater exchange. The FO-DTS data sets confirm the hydrologic significance of the variability identified in the CWEI and reveal a pattern of highly focused exchange, concentrated at springs where the Hanford Formation is thickest. Our findings illustrate how the combination of CWEI and FO-DTS technologies can characterize surface water-groundwater exchange in a complex, coupled river-aquifer system.

    2015-11-01

    Full Text Available Traditionally believed to be the result of maladaptive development, bullying perpetration is increasingly being viewed as a potentially adaptive behavior. We were interested in determining whether adolescents who bully others enjoy a key evolutionary benefit: increased dating and mating (sexual opportunities. This hypothesis was tested in two independent samples consisting of 334 adolescents and 144 university students. The data partly supported our prediction that bullying, but not victimization, would predict dating behavior. The data for sexual behavior more clearly supported our hypothesis that bullying behavior predicts an increase in sexual opportunities even when accounting for age, sex, and self-reports of attractiveness, likeability, and peer victimization. These results are generally congruent with the hypothesis that bullying perpetration is, at least in part, an evolutionary adaptive behavior.

    This research work is focused on the competitive dynamics approach and rivalry studies between competitors. It develops theses recent perspectives and particularly multi-market competition (also called multipoint competition) in de-regulated industries (network utilities). Indeed, competitive behaviours in liberalized industries are still badly-known. To conduct this research, we decided to analyze a selection of companies (EDF, Electrabel, Endesa, Enel, Gaz de France, Poweo, Direct Energie..) settled on the French electricity market presently in the course of liberalization (1996 - 2006). This qualitative research, through longitudinal case studies, has been developed thanks to a CIFRE agreement (between the French Ministry of Research and the firm Electrabel France) including action research and participant observation. Using multidimensional strategic sequences, we identified two periods, the first one characterized by a confrontation movement and a second one by mutual forbearance. We argue that after learning the rules of a newly liberalized market (confrontation, diversification, internationalization), competitors rapidly and collectively shift there positions towards a focused European strategy based on the gas-electricity convergence. The development of multi-market competition has conducted to mutual forbearance, which was particularly profitable to the major participants. Integrated strategy (market and non-market) appears as an important driver for legitimizing theses behaviours. (author)

    2011-09-15

    After over 25 years, the use of electron spin resonance (ESR) is well-established in dating sites of geological, paleontological and archaeological interest. Like any scientific technique, there have been changes in understanding and in methodology. Improvements have not, however, changed the observation that external dose calculations are still a significant source of uncertainty in ages. Examples from Europe, Africa and the Americans illustrate this point. For Pradayrol Cave (France), the occupation age, 330 ka, is unchallenged, making this the oldest known Neanderthal site in France. For Roc de Marsal, also in France, on the other hand, discrepancies between TL and sedimentary dose rates imply substantial differences in interpretation. In the Western Egyptian Desert, where artifacts and datable material are not well-correlated, the dating results show consistency with expectations based on global climate change, even in deflated sites. Climate change is also the question in geological studies in the Bahamas where, despite concerns about cosmic dose history, ESR dates confirm other evidence for sea level changes. We show that an uncertain age is not the same as an impossible one.

Fine grains are more completely reset during faulting, and a plot of age vs. grain size shows a plateau for grains below critical size; these grains are presumed to have been completely zeroed by the last fault activity. We carried out ESR dating of fault rocks collected near the Gori nuclear reactor. Most of the ESR signals of fault rocks collected from the basement are saturated. This indicates that the last movement of the faults had occurred before the Quaternary period. However, ESR dates from the Oyong fault zone range from 370 to 310 ka. Results of this research suggest that long-term cyclic fault activity of the Oyong fault zone continued into the Pleistocene.

  10. Electric Guitar and Violin

    Science.gov (United States)

    Gough, Colin

    Almost all the instruments described in this book have their origins in historical cultures dating back over many centuries. In contrast, the electric guitar and violin are clearly twentieth-century innovations. They are products of the electronics age following invention of the rectifying thermionic valve (tube) by John Ambrose Fleming in 1904, the amplifying triode valve (tube) by Lee de Forest in 1907, and the vacuum-filled amplifying valve (tube) by Irving Langmuir in 1915. By 1916, such valves were already being used in radio receivers, and important advances were being made in microphone, amplifier, and loudspeaker design. This, and the increasingly wide distribution of mains electricity in the 1920s, provided the technology and infrastructure for the development of the electric guitar and violin and their lower-pitched relations - the bass guitar, viola, cello, and string-bass. Although we focus here on the electric guitar and violin, almost everything discussed in this chapter is also relevant to their lower-pitched relations.

  11. Electric generators: Roesel

    Energy Technology Data Exchange (ETDEWEB)

    Segaser, C.L.

    1977-04-01

    A new and unique type of electrical generator is described that will provide constant frequency output (within 0.01% or better) regardless of rotational speed variations. It accomplishes this with no added bulk over conventional generators, and with excellent efficiency. The same principle that permits constant frequency output also provides the means for output voltage regulation with varying drive speed and/or varying load. Onsite power generation aspects of the Integrated Community Energy Systems (ICES) concept include the requirement to follow community electric loads and the possible use of internal combustion piston engines with waste heat recovery to drive electric generators. The diesel engine is a prime candidate from commercially available technologies for which part-load shaft efficiency is better at reduced speed than for constant-speed operation required by conventional AC generators. The unique characteristics of the Roesel generator allow prime mover speed to decrease with load and offer improved engine-generator system efficiency in ICES applications.

  12. Etiology of Teen Dating Violence among Adolescent Children of Alcoholics.

    Livingston, Jennifer A; Eiden, Rina D; Lessard, Jared; Casey, Meghan; Henrie, James; Leonard, Kenneth E

    2018-03-01

    Family processes in early life have been implicated in adolescent involvement in teen dating violence, yet the developmental pathways through which this occurs are not well understood. In this study, etiological pathways from parental psychopathology and marital conflict in infancy to involvement in dating violence in late adolescence were examined in a sample of children at high-risk due to parental alcohol problems. Families (N = 227) recruited when the child was 12 months of age were assessed at 12-, 24-, 36-months, kindergarten, 6th, 8th, and 12th grades. Slightly more than half of the children were female (51%) and the majority were of European American descent (91%). Parental psychopathology in infancy was indirectly associated with teen dating violence in late adolescence via low maternal warmth and self-regulation in early childhood, externalizing behavior from kindergarten to early adolescence, and sibling problems in middle childhood. Marital conflict was also indirectly associated with teen dating violence via child externalizing behavior. Maternal warmth and sensitivity in early childhood emerged as an important protective factor and was associated with reduced marital conflict and increased child self-regulation in the preschool years as well as increased parental monitoring in middle childhood and early adolescence. Family processes occurring in the preschool years and in middle childhood appear to be critical periods for creating conditions that contribute to dating violence risk in late adolescence. These findings underscore the need for early intervention and prevention with at-risk families.

    Offering a concise but complete survey of the common features of the microstructure of electricity markets, this book describes the state of the art in the different proposed electricity price models for pricing derivatives and in the numerical methods used to price and hedge the most prominent derivatives in electricity markets, namely power plants and swings. The mathematical content of the book has intentionally been made light in order to concentrate on the main subject matter, avoiding fastidious computations. Wherever possible, the models are illustrated by diagrams. The book should allow prospective researchers in the field of electricity derivatives to focus on the actual difficulties associated with the subject. It should also offer a brief but exhaustive overview of the latest techniques used by financial engineers in energy utilities and energy trading desks.

    Energy Technology Data Exchange (ETDEWEB)

    Hurst, R.W.; Feltham, P. (eds.)

    2004-05-01

    This handbook outlines the important role that electric motors play in modern society. It covers the field of motor applications from various motor types to their use and repair. It also presents practical applications of electric motors and methods on motor efficiency. More than half of all electricity generated, and 75 per cent of all industrial electricity consumption is consumed by electric motors. Electrical personnel must be aware of all factors involved in electric motors in order to choose and apply the appropriate size of electric motor. These factors include efficiency, sizing and proper application. The efficient use and maximum life expectancy of electric motors depends on proper motor protection, control and maintenance. This handbook includes articles from leading experts on electric motors in modern electrical systems. The content includes: design considerations; proper electric motor sizing techniques; optimal electric motor application; electric motor protection technology; electric motor control principles; electric motor maintenance and troubleshooting; induction electric motors; electric motor bearing currents; electric motor bearing lubrication; electromagnetism; electric motor enclosures; electric motor testing; electric motor repair; DC electric motor; electric motor starters; electric motor brushes; industrial electric motors; electric motor diagrams; AC electric motors; electric motor wiring; electric motor service; electric motor rewinding; electric motor winding; diagram of electric motor wiring; electric motor kit; and, troubleshooting electric motors.

  19. Sexual assault in dating relationships.

    Science.gov (United States)

    Rhynard, J; Krebs, M; Glover, J

    1997-03-01

    This article focuses on acquaintance rape, which under Canadian law constitutes a form of sexual assault. Frequency of acquaintance rape often is underestimated due to under-reporting, resulting in a local perception that acquaintance rape rarely occurs in a small Canadian community. A survey was conducted to determine whether acquaintance rape does occur in this community. One hundred sixty-four male and female students from grades 8-12 completed a questionnaire. Twenty-six percent of respondents reported being forced into some type of sexual activity. Based on the survey, this article explores the type of force used, the relationship between acquaintance rape and use of alcohol and drugs, and the relationship between acquaintance rape and the ability to indicate to a partner to stop a behavior. Results confirmed a need to develop programs to prevent rather than merely respond to issues of sexual assault on a date.

  20. Retrospective Birth Dating of Cells

    Energy Technology Data Exchange (ETDEWEB)

    L.Spalding, K; Bhardwaj, R D; Buchholz, B A; Druid, H; Frisen, J

    2005-04-19

    The generation of cells in the human body has been difficult to study and our understanding of cell turnover is limited. Extensive testing of nuclear weapons resulted in a dramatic global increase in the levels of the isotope {sup 14}C in the atmosphere, followed by an exponential decrease after the test ban treaty in 1963. We show that the level of {sup 14}C in genomic DNA closely parallels atmospheric levels, and can be used to establish the time point when the DNA was synthesized and cells were born. We use this strategy to determine the age of cells in the cortex of the adult human brain, and show that whereas non-neuronal cells are exchanged, occipital neurons are as old as the individual, supporting the view that postnatal neurogenesis does not take place in this region. Retrospective birth dating is a generally applicable strategy that can be used to measure cell turnover in man under physiological and pathological conditions.

  1. Blind-date Conversation Joining

    Directory of Open Access Journals (Sweden)

    Luca Cesari

    2013-07-01

    Full Text Available We focus on a form of joining conversations among multiple parties in service-oriented applications where a client may asynchronously join an existing conversation without need to know in advance any information about it. More specifically, we show how the correlation mechanism provided by orchestration languages enables a form of conversation joining that is completely transparent to clients and that we call 'blind-date joining'. We provide an implementation of this strategy by using the standard orchestration language WS-BPEL. We then present its formal semantics by resorting to COWS, a process calculus specifically designed for modelling service-oriented applications. We illustrate our approach by means of a simple, but realistic, case study from the online games domain.

    This report aims at filling up some gaps in the French legislation relative to the determination of electricity and natural gas regulated tariffs and to the beneficiaries of these tariffs. It makes a synthesis of four proposals of law dealing with: the possibility for end-users and small companies to benefit again of the regulated electricity prices (proposals no 369 and 149), the permission of reversibility in the exercise of the rights relative to the eligibility for the purchase of electric power (proposal no 427), and the preservation of households' purchasing power by keeping up the regulated prices of electricity and natural gas (proposal no 462). The different articles are examined and some amendments are proposed by the commission. (J.S.)

    McAllister, Iain Wilson

    2002-01-01

    The adoption of a field-theoretical approach to problems arising in the framework of electrical insulation is discussed with reference to six main topics, which have been addressed over the last 30 years. These include uniform field electrodes, Green's differential equation, electrode surface...... roughness, induced charge, electrostatic probes, and partial discharge transients, together with several follow-on aspects. Each topic is introduced and thereafter the progress achieved through the use of a field-theoretical approach is reviewed. Because the topics cover a wide spectrum of conditions......, it is amply demonstrated that such an approach can lead to significant progress in many areas of electrical insulation....

    July 2007 was an important milestone for the liberalization of the Portuguese electricity sector. After this date, only two Power Purchase Agreements (PPA) are in force. REN Trading has to resale the energy generated by th two producers with a PPA in the market. The difference between the costs of the energy produced, which include costs resulting from the CO2 allowances, and the gains of reselling this energy in the market is transferred to the consumers through the regulated tariffs. In the autonomous regions of Azores and of Madeira, generation costs are regulated, including CO2 allowances costs. The Portuguese Energy Regulator (ERSE) created a regulatory mechanism which aims to give to the regulated companies an incentive to administrate the CO2 allowances in an efficient way. This mechanism is based on the profit and the losses sharing between the companies and the costumers resulting from the CO2 allowances trading. After one year of application, in a context of great uncertainty for the carbon market, like other markets, the main results of the incentive mechanism are presented in this paper.

    Full Text Available This paper investigates deregulation of electricity market focusing on electricity prices and drivers of demand for electrical energy in industry in Slovenia. The patterns in evolution of real electricity price developments and the three main components of the electricity price are calculated: liberalized market share for purchased electricity price, regulated infrastructure share for use of electricity network grids and mandatory state charges in the sale of electricity (duty, excise duty and value-added tax. To calculate the real value of electricity prices, producer price index of industrial commodities for electricity prices in industry is used as deflator and implicit deflator of gross domestic product for the size of the economy. In the empirical econometric part is used regression analysis for the amount electricity consumption in the industry depending on the real gross domestic product, direct and cross-price elasticity for natural gas prices in the industry. The results confirmed volatility in real electricity price developments with their increasing tendency and the increasing share of different taxes and state charges in the electricity prices for industry. Demand for electrical energy in industry is positively associated with gross domestic product and price of natural gas as substitute for electrical energy in industry use, and negatively associated with prices of electrical energy for industry.

    Abahmane, Larbi

    2017-01-01

    A number of public and private laboratories are working on date palm micropropagation to meet the increasing worldwide demand for date palm planting material. A standardized direct organogenesis protocol exists for the production of date palm plantlets to maintain the genetic fidelity of regenerated plants. Organogenesis has the advantage of using low concentrations of plant growth regulators and avoiding the callus phase. In addition, direct regeneration of vegetative buds minimizes the risk of somaclonal variation among plant regenerants. However, in vitro multiplication cycles should be limited in duration by frequent renewal of plant material. This chapter describes a simple and routine organogenesis protocol for date palm multiplication using shoot tip explants.

With this background, we can define a cast of principles governing the behavior of an electronic administration. The leading roles will fall to those principles that aim to guarantee equality while prohibiting discrimination against the citizenry, thereby combating what has come to be known as the “digital divide.”Actualmente, nos encontramos inmersos en un proceso de globalización y tecnificación al que las Administraciones públicas, como parte integrante de la sociedad, no pueden permanecer ajenas.

  18. Electrical stimulation in exercise training

    Science.gov (United States)

    Kroll, Walter

    1994-01-01

    Electrical stimulation has a long history of use in medicine dating back to 46 A.D. when the Roman physician Largus found the electrical discharge of torpedo fishes useful in the treatment of pain produced by headache and gout. A rival Greek physician, Dioscorides, discounted the value of the torpedo fish for headache relief but did recommend its use in the treatment of hemorrhoids. In 1745, the Leyden jar and various sized electrostatic generators were used to treat angina pectoris, epilepsy, hemiplegia, kidney stones, and sciatica. Benjamin Franklin used an electrical device to treat successfully a young woman suffering from convulsive fits. In the late 1800's battery powered hydroelectric baths were used to treat chronic inflammation of the uterus while electrified athletic supporters were advertised for the treatment of male problems. Fortunately, such an amusing early history of the simple beginnings of electrical stimulation did not prevent eventual development of a variety of useful therapeutic and rehabilitative applications of electrical stimulation. Over the centuries electrical stimulation has survived as a modality in the treatment of various medical disorders with its primary application being in the rehabilitation area. Recently, a surge of new interest in electrical stimulation has been kindled by the work of a Russian sport scientist who reported remarkable muscle strength and endurance improvements in elite athletes. Yakov Kots reported his research on electric stimulation and strength improvements in 1977 at a Canadian-Soviet Exchange Symposium held at Concordia University in Montreal. Since then an explosion of new studies has been seen in both sport science and in medicine. Based upon the reported works of Kots and the present surge of new investigations, one could be misled as to the origin of electrical stimulation as a technique to increase muscle strength. As a matter of fact, electric stimulation has been used as a technique to improve

    2013-01-01

    Research over the last 20 years has provided an increased understanding of intimate relationships in later life; however, dating in later life remains largely unexplored. The purpose of this study was to examine the meanings of dating for women in later life. In this study, dating was examined through semistructured, in-depth interviews with 14 women ages 64 to 77 who had all dated in later life. Themes that emerged from an interpretative phenomenological analysis included multiple meanings of dating in later life, how dating in later life compared to earlier points in life, and dating in the future.

    The judge was driving back late one cold winter night. Entering the garage, the battery-charging indicator in his wirelessly powered electric car came on. "Home at last," crossed his mind. He swiped his personal smartcard on the front-door detector to be let in. He heard a "charging" beep from his mobile phone. The blinking cursor on the half-finished e-mail on the laptop had been waiting all day on the side table. He picked the computer up and walked towards his desk. "Good evening, your honour. Your wirelessly heated robe," said the butler-robot as it approached from the kitchen. Putting on the electric garment, he sat on the medical desk chair. His artificial heart was now beating faster.

    Colman, Steven M.; Pierce, K.L.; Birkeland, P.W.

    1987-01-01

    Classification of Quaternary dating methods should be based on the level of quantitative information and the degree of confidence contained in the age estimates produced by the dating methods. We recommend the use of the terms numerical-age, calibrated-age, relative-age, and correlated-age to describe these levels. We also classify dating methods by type into sideral, isotopic, radiogenic, chemical and biological, geomorphic, and correlation methods. The use of "absolute" is inappropriate for most dating methods, and should be replaced by "numerical." The use of "date" should be minimized in favor of "age" or "age estimate." We recommend use of the abbreviations ka and Ma for most ages; calender dates can be used where appropriate and yr B.P. can be used for radiocarbon ages. ?? 1987.

  4. Directing lineage specification of human mesenchymal stem cells by decoupling electrical stimulation and physical patterning on unmodified graphene

    The organization and composition of the extracellular matrix (ECM) have been shown to impact the propagation of electrical signals in multiple tissue types. To date, many studies with electroactive biomaterial substrates have relied upon passive electrical stimulation of the ionic media to affect cell behavior. However, development of cell culture systems in which stimulation can be directly applied to the material - thereby isolating the signal to the cell-material interface and cell-cell contracts - would provide a more physiologically-relevant paradigm for investigating how electrical cues modulate lineage-specific stem cell differentiation. In the present study, we have employed unmodified, directly-stimulated, (un)patterned graphene as a cell culture substrate to investigate how extrinsic electrical cycling influences the differentiation of naïve human mesenchymal stem cells (hMSCs) without the bias of exogenous biochemicals. We first demonstrated that cyclic stimulation does not deteriorate the cell culture media or result in cytotoxic pH, which are critical experiments for correct interpretation of changes in cell behavior. We then measured how the expression of osteogenic and neurogenic lineage-specific markers were altered simply by exposure to electrical stimulation and/or physical patterns. Expression of the early osteogenic transcription factor RUNX2 was increased by electrical stimulation on all graphene substrates, but the mature marker osteopontin was only modulated when stimulation was combined with physical patterns. In contrast, the expression of the neurogenic markers MAP2 and β3-tubulin were enhanced in all electrical stimulation conditions, and were less responsive to the presence of patterns. These data indicate that specific combinations of non-biological inputs - material type, electrical stimulation, physical patterns - can regulate hMSC lineage specification. This study represents a substantial step in understanding how the interplay of

    2017-09-01

    Full Text Available Electrical signaling in higher plants is required for the appropriate intracellular and intercellular communication, stress responses, growth and development. In this review, we have focus on recent findings regarding the electrical signaling, as a major regulator of the systemic acquired acclimation (SAA and the systemic acquired resistance (SAR. The electric signaling on its own cannot confer the required specificity of information to trigger SAA and SAR, therefore, we have also discussed a number of other mechanisms and signaling systems that can operate in combination with electric signaling. We have emphasized the interrelation between ionic mechanism of electrical activity and regulation of photosynthesis, which is intrinsic to a proper induction of SAA and SAR. In a special way, we have summarized the role of non-photochemical quenching and its regulator PsbS. Further, redox status of the cell, calcium and hydraulic waves, hormonal circuits and stomatal aperture regulation have been considered as components of the signaling. Finally, a model of light-dependent mechanisms of electrical signaling propagation has been presented together with the systemic regulation of light-responsive genes encoding both, ion channels and proteins involved in regulation of their activity. Due to space limitations, we have not addressed many other important aspects of hormonal and ROS signaling, which were presented in a number of recent excellent reviews.

  11. Topics on electricity trade

    Energy Technology Data Exchange (ETDEWEB)

    Skytte, K.

    2001-07-01

    The first chapter in this thesis is a survey of studies on electricity trade, which has been included in order to show how subjects in this thesis fit into this aspect of energy research. Transitions from centralised monopolies to liberalised electricity markets have been inaugurated in the northern European countries during the last decade. The backgrounds and speed of transitions differ within the countries. Where Norway liberalised its electricity market in order to stabilise the prices, EU urged a liberalisation in order to make the electricity supply industry more effective. Together with national liberalisation, the opening of the cross border trade between the countries is also urged. The first paper in this thesis describes those different liberalisation processes within northern Europe and discusses problems that may arise in a transition period for integrating the countries into a common electricity market with efficient cross-border competition. Before the liberalisation process started, the electricity generation was determined by a central load dispatch at known prices. The introduction of competition has necessitated the creation of new competitive markets, power exchanges and financial markets where generation and prices are determined by demand and supply on the markets. One implication of this is that investments in new plants shall be made under levels of uncertainty about future prices. The second paper in this thesis analyses the importance of introducing uncertainty in energy-economic modelling of the electricity supply sector. Another implication, which arises on introducing a new market structure and power exchanges, is that the design of the power exchanges influences the price setting on the markets. The third paper of this thesis analyses the price setting on the regulating power market on the Nordic power exchange Nord Pool. More precisely, the paper reveals the pattern of the prices on the regulating power market by analysing the cost of

    Holmes, Kristin; Sher, Leo

    2013-01-01

    The aim of this paper is to assess the possible consequences of adolescent physical, emotional and sexual dating violence through a review of the literature on the topic. An electronic search of major biomedical bibliographic databases (Pubmed, ISI, PsycINFO) was used to retrieve articles providing information on the prevalence rates, risk factors, associated consequences and possible preventive measures for adolescent dating violence across different populations. Currently, there have been few longitudinal studies conducted to identify potential risk factors for entering a violent dating relationship in adolescence. Risky behaviors such as early sexual intercourse may predispose someone for victimization. Dating violence itself is also a predictor of future dating violence. Adolescent dating violence was associated with an increase in other violence-related behaviors, substance use, depression, poorer educational outcomes, posttraumatic stress, unhealthy weight control and risky sexual behavior. The association between adolescent dating violence and an increase in suicidal behavior is a major public health concern. Future research should focus on longitudinal studies so that a causal relationship between dating violence and suicidality may be better understood.

  16. Electric industry restructuring review

    Energy Technology Data Exchange (ETDEWEB)

    Slocum Hollis, S. [Duane Morris LLP, Washington, DC (United States)

    2004-07-01

    Restructuring of the electric power industry began in the early 1990's in many jurisdictions in the United States. Restructuring was an attempt to offer large industrial customers lower rates and freedom from regulation for generators and traditional public utilities. The move has gained most attention in the past two years as some utilities report high profits while others, such as Pacific Gas and Electric Co., the largest investor-owned utility in the United States, is in bankruptcy. The August 2003 blackout in the Midwest and Northeast United States and Canada also raised questions regarding electric reliability. The question now remains whether markets should be allowed to determine the need for services and the prices to be charged, and who is in charge in the imperfect market. The Federal Energy Regulatory Commission's (FERC) Order 2000 led to the formation of a Regional Transmission Organizations which is still in the implementation stage. Its influence on precursor Order numbers 888 and 889 were discussed in this paper with reference to independent system operators; regional transmission organizations; standard market design; rates and pricing devices; congestion management; market monitoring; market investigations; reliability measures; OASIS and other information access; interconnection policy; jurisdiction; mergers and merger policy; standards of conduct; policing affiliates; municipal utilities; stranded costs; and, state restructuring scorecards. refs.

  17. Electric vehicle drive systems

    Appleyard, M.

    1992-01-01

    New legislation in the State of California requires that 2% of vehicles sold there from 1998 will be 'zero-emitting'. This provides a unique market opportunity for developers of electric vehicles but substantial improvements in the technology are probably required if it is to be successfully exploited. There are around a dozen types of battery that are potentially relevant to road vehicles but, at the present, lead/acid and sodium—sulphur come closest to combining acceptable performance, life and cost. To develop an efficient, lightweight electric motor system requires up-to-date techniques of magnetics design, and the latest power-electronic and microprocessor control methods. Brushless machines, coupled with solid-state inverters, offer the most economical solution for mass production, even though their development costs are higher than for direct-current commutator machines. Fitted to a small car, even the highest energy-density batteries will only provide around 200 km average range before recharging. Therefore, some form of supplementary on-board power generation will probably be needed to secure widespread acceptance by the driving public. Engine-driven generators of quite low power can achieve useful increases in urban range but will fail to qualify as 'zero-emitting'. On the other hand, if the same function could be economically performed by a small fuel-cell using hydrogen derived from a methanol reformer, then most of the flexibility provided by conventional vehicles would be retained. The market prospects for electric cars would then be greatly enhanced and their dependence on very advanced battery technology would be reduced.

    2012-08-01

    Little is known about dyadic processes that lead to adolescent dating violence. The purpose of this study was to examine the phenomenon of relationship ambiguity in adolescent dating relationships to better understand how ambiguity contributes to violence and aggression between dating partners. Data were drawn from 88 narratives of young adults who had participated in a study on adolescent dating violence. Interpretive phenomenology was used to produce an in-depth description of the phenomenon of relationship ambiguity. Relationship ambiguity results in differing expectations between partners regarding closeness and intimacy, fidelity, and obligation. These differences lead to conflicts that set the stage for violence and aggression in adolescent dating relationships. A series of recommendations for clinicians working with adolescents are presented. © 2012 Wiley Periodicals, Inc.

    Propulsion is required for satellite motion in outer space. The displacement of a satellite in space, orbit transfer and its attitude control are the task of space propulsion, which is carried out by rocket engines. Electric propulsion uses electric energy to energize or accelerate the propellant. The electric propulsion, which uses electrical energy to accelerate propellant in the form of plasma, is known as plasma propulsion. Plasma propulsion utilizes the electric energy to first, ionize the propellant and then, deliver energy to the resulting plasma leading to plasma acceleration. Many types of plasma thrusters have been developed over last 50 years. The variety of these devices can be divided into three main categories dependent on the mechanism of acceleration: (i) electrothermal, (ii) electrostatic and (iii) electromagnetic. Recent trends in space exploration associate with the paradigm shift towards small and efficient satellites, or micro- and nano-satellites. A particular example of microthruster considered in this paper is the micro-cathode arc thruster (µCAT). The µCAT is based on vacuum arc discharge. Thrust is produced when the arc discharge erodes some of the cathode at high velocity and is accelerated out the nozzle by a Lorentz force. The thrust amount is controlled by varying the frequency of pulses with demonstrated range to date of 1-50 Hz producing thrust ranging from 1 µN to 0.05 mN.

    Full Text Available Introduction: Agricultural prices are one of the most important tools for resource allocation in an economy. Evidence suggests that, agricultural prices in comparison with other goods prices have more volatility. If these volatility leads to asymmetric price transmission, this subject will be very important. In other words, if changes in the market price are not absolutely transferred between levels, asymmetric price transmission has occurred, which is leading to increased marketing margin. Price transmission in different market levels related to the marketing efficiency, which also affected the welfare of producers and consumers. Dates, among all horticultural crops, with a share of 10% of the planted area in our country, after the pistachios and grapes were located in the third highest level, and with 6.5 percent of the total horticulture products after grapes, apples and oranges, are in the fourth highest level. Iran Dates from global production share is 14% in 2012. Despite of important Dates, Dates producers, suffer from volatility and low price of this product. Dates owners considerable expenses for crop production, including purchasing, supply of fertilizers and pesticides, irrigation (water and electricity costs and the cost of labor in planting and harvesting spent, but in most cases they not only benefit from production, but also sell it below cost. According to the phenomena that Dates owners are not marketed through cooperatives, so farmers are the victims and intermediaries benefited. In such an environment, the marketing of dates, have a significant impact on how prices transmitted. In policy debates, asymmetric price transmission is a phenomenon that arises from imperfect competition in the market and it would be imposing additional costs to consumers. Having this information will help policy makers to adopt the correct policies. Materials and Methods: To achieve the aims of this study which determines the mechanism of price

    Electricity resource planning is the process of identifying longer-term investments to meet electricity reliability requirements and public policy goals at a reasonable cost. Resource planning processes provide a forum for regulators, electric utilities, and electricity industry stakeholders to evaluate the economic, environmental, and social benefits and costs of different investment options. By facilitating a discussion on future goals, challenges and strategies, resource planning processes often play an important role in shaping utility business decisions. Resource planning emerged more than three decades ago in an era of transition, where declining electricity demand and rising costs spurred fundamental changes in electricity industry regulation and structure. Despite significant changes in the industry, resource planning continues to play an important role in supporting investment decision making. Over the next two decades, the electricity industry will again undergo a period of transition, driven by technological change, shifting customer preferences and public policy goals. This transition will bring about a gradual paradigm shift in resource planning, requiring changes in scope, approaches and methods. Even as it changes, resource planning will continue to be a central feature of the electricity industry. Its functions — ensuring the reliability of high voltage (“bulk”) power systems, enabling oversight of regulated utilities and facilitating low-cost compliance with public policy goals — are likely to grow in importance as the electricity industry enters a new period of technological, economic and regulatory change. This report examines the future of electricity resource planning in the context of a changing electricity industry. The report examines emerging issues and evolving practices in five key areas that will shape the future of resource planning: (1) central-scale generation, (2) distributed generation, (3) demand-side resources, (4

    Dating violence is commonly perpetrated in adolescence, making it imperative to understand risk factors in order to inform prevention efforts. Although individual norms supporting dating violence are strongly related to its perpetration, few studies have examined their longitudinal impact. Moreover, the influence of class norms (i.e., norms for students in the same grade, cohort, and school) supporting dating violence on perpetration has rarely been studied. The current study examined longitudinal relationships between individual and class norms supporting dating violence and perpetration of physical and psychological dating violence. Participants were two cohorts of sixth graders from 37 schools who were in dating relationships at Wave 1 and 6 months later at Wave 2 (N = 2,022; 43% female; 52% African American, 21% Latino/a, 20% White, and 7% other). The analyses used a multilevel approach, with students represented at Level 1 and classes (n = 74) at Level 2. The models tested direct effects of Wave 1 individual and class norms supporting dating violence on subsequent changes in perpetration of dating violence at Wave 2 and the extent to which gender moderated these relationships. The findings indicated that greater individual norms supporting male dating violence predicted greater change in perpetration of physical and psychological dating violence and greater individual norms supporting female dating violence predicted greater change in perpetration of psychological dating violence. Greater class norms supporting male dating violence predicted greater change in perpetration of physical dating violence; whereas greater class norms supporting female dating violence predicted less change in perpetration of physical dating violence. These findings highlight the need to address norms in early adolescence.

    Recent global experiences in electricity restructuring were examined with particular emphasis on how policy decisions have contributed to the current uncertainties for investment in electricity generation and transmission. California, Ontario, Alberta, and the United Kingdom were among the jurisdictions mentioned. It was noted that improved public policies that reduce uncertainties would encourage and manage industry restructuring while achieving improved economics and environmental objectives. Reform of economic regulations has been characterized by the following 3 trends: (1) liberalization, in which prices are determined by competitive markets, (2) state retrenchment, in which activities previously restricted by regulatory barriers are returned to the private sector, and (3) new regulatory design, in which new regulations are introduced to motivate public interest in a more competitive framework. It was noted that electricity is unlike other commodities. It cannot be economically stored and the market is characterized by volatile spot prices. The supply is not inexhaustible either. The electricity market has been more difficult to restructure than any other market that was used as a model for deregulation. No one jurisdiction has been completely successful in electricity restructuring, but each has its own merits and drawbacks. This document also discussed the impact that electricity restructuring will have on the climate change challenge and Canada's commitment under the Kyoto Protocol. When a jurisdiction moves to competitive power generation, generators look for the least expensive generation options, which are not necessarily the most environmentally desirable ones. It was emphasized that there is a need for long-term, integrated planning that addresses policy objectives for market regulation, climate change, and air quality. 38 refs., 1 tab., 1 fig.

  8. Date palm micropropagation: Advances and applications

    Directory of Open Access Journals (Sweden)

    Jameel Mohammed Al-Khayri

    Full Text Available ABSTRACT Date palm (Phoenix dactylifera L. is a fruit tree resilient to adverse climatic conditions predominating in hot arid regions of the Middle East and North Africa. The date fruit contains numerous chemical components that possess high nutritional and medicinal values. Traditional propagation by offshoots is inefficient to satisfy current demands for date palm trees. Alternatively, micropropagation provides an efficient means for large-scale propagation of date palm cultivars. Both somatic embryogenesis and organogenesis, either directly or indirectly though the callus phase, have been demonstrated in date palm in vitro regeneration. Culture initiation commonly utilizes shoot-tip explants isolated from young offshoots. Recently, the immature inflorescences of adult trees were utilized as an alternative nondestructive source of explants. In addition to the nature of the explant used, successful plant regeneration depends on the cultivar, composition of the culture medium and physical status. Challenges of date palm micropropagation include long in vitro cycle, latent contamination, browning, somaclonal variation as well as ex vitro acclimatization and transplanting. A remarkable amount of research investigating these factors has led to optimized protocols for the micropropagation of numerous commercially important cultivars. This has encouraged the development of several international commercial tissue culture laboratories. Molecular characterization provides an assurance of genetic conformity of regenerated plantlets, a key feature for commercial production. This article describes date palm micropropagation protocols and also discusses recent achievements with respect to somaclonal variation, molecular markers, cryopreservation and future prospects.

    The intensity of thermoluminescence light emitted by a crystal is a function of radiation dose. The number of defects or of radicals in a crystal or organic substances is also a function of radiation dose. Since such defects or radicals present EPR signals, the EPR intensity is also a function of radiation dose. These facts are basis for radiation dosimetry and can be applied in dating of archaeological potteries or other materials, as well as in dating geological substances such as sediments, caves speleothemes, animal teeth and bones. Recent investigation on sensitized quartz based dosimeters and dating calcite covering ancient wall painting to find early settlers in Brazil will be presented. (Author)

    Electric vehicle has been developed through several decades as transportation mean, without paying sufficient attention of its utilization for other purposes. Recently, the utilization of electric vehicle to support the grid electricity has been proposed and studied intensively. This utilization covers several possible services including electricity storage, spinning reserve, frequency and voltage regulation, and emergency energy supply. This study focuses on theoretical and experimental analysis of utilization of electric vehicles and their used batteries to support a small-scale energy management system. Charging rate of electric vehicle under different ambient temperature (seasonal condition) is initially analyzed to measure the correlation of charging rate, charging time, and state-of-charge. It is confirmed that charging under warmer condition (such as in summer or warmer region) shows higher charging rate than one in colder condition, therefore, shorter charging time can be achieved. In addition, in the demonstration test, each five electric vehicles and used batteries from the same electric vehicles are employed and controlled to support the electricity of the office building. The performance of the system is evaluated throughout a year to measure the load leveling effect during peak-load time. The results show that the targeted peak-load can be shaved well under certain calculated peak-shaving threshold. The finding confirms that the utilization of electric vehicle for supporting the electricity of grid or certain energy management system is feasible and deployable in the future.

    Introduction Theoretic models suggest that associations between substance use and dating violence perpetration may vary in different social contexts, but few studies have examined this proposition. The current study examined whether social control and violence in the neighborhood, peer, and family contexts moderate the associations between substance use (heavy alcohol use, marijuana, and hard drug use) and adolescent physical dating violence perpetration. Methods Adolescents in the eighth, ninth, and tenth grades completed questionnaires in 2004 and again four more times until 2007 when they were in the tenth, 11th and 12th grades. Multilevel analysis was used to examine interactions between each substance and measures of neighborhood, peer, and family social control and violence as within-person (time-varying) predictors of physical dating violence perpetration across eighth through 12th grade (N=2,455). Analyses were conducted in 2014. Results Physical dating violence perpetration increased at time points when heavy alcohol and hard drug use were elevated; these associations were weaker when neighborhood social control was higher and stronger when family violence was higher. Also, the association between heavy alcohol use and physical dating violence perpetration was weaker when teens had more-prosocial peer networks and stronger when teens’ peers reported more physical dating violence. Conclusions Linkages between substance use and physical dating violence perpetration depend on substance use type and levels of contextual violence and social control. Prevention programs that address substance use–related dating violence should consider the role of social contextual variables that may condition risk by influencing adolescents’ aggression propensity.

    Background: Date is one of the foodstuffs that are produced in tropical areas and used worldwide. Conventionally, methyl bromide and phosphine are used for date disinfection. The toxic side effects of these usual disinfectants have led food scientists to consider safer agents such as ozone for disinfection, because food safety is a top priority. The present study was performed to investigate the possibility of replacing common conventional disinfectants with ozone for date disinfection and microbial load reduction. Materials and Methods: In this experimental study, date samples were ozonized for 3 and 5 hours with 5 and 10 g/h concentrations and packed. Ozonized samples were divided into two groups and kept in an incubator which was maintained at 25°C and 40°C for 9 months. During this period, every 3 month, microbial load (bacteria, mold, and yeast) were examined in ozonized and non-ozonized samples. Results: This study showed that ozonization with 5 g/h for 3 hours, 5 g/h for 5 hours, 10 g/h for 3 hours, and 10 g/h for 5 hours leads to about 25%, 25%, 53%, and 46% reduction in date mold and yeast load and about 6%, 9%, 76%, and 74.7% reduction in date bacterial load at baseline phase, respectively. Appropriate concentration and duration of ozonization for microbial load reduction were 10 g/h and 3 hours. Conclusion: Date ozonization is an appropriate method for microbial load reduction and leads to an increase in the shelf life of dates. PMID:24124432

    The design of electricity markets, from pioneers like England and Wales, the Nordic countries, parts of the US, to the more recent additions in Eastern Europe, Africa and South America, carry a lot of similarities. At the same time, there are also distinct differences in the choices made. Is it possible at this stage to conclude that one design works better than the others? In that case - what seems to be working and what remains to be solved? Other important topics to study within this field are optimal investments in interconnection capacities, integration of electricity markets, market power and demand response. The following presentations from the conference are available at the conference web site: Session 1: Market and Politics - from a bird's eye perspective: How liberalised have liberalised electricity markets become?; What is Driving Investments in the Power Sector; Electricity Market Design in the U.S.A.: More Market Or More Politics?; Politics of Energy Policy and Marketing of Energy Markets in the EU - Driving Forces Behind EU Energy Policy and Market Development; Session 2: Experiences from Different Models of Market Design: Using Forward Markets to Improve Electricity Market Design: examples from USA and Colombia; The Texas Deregulated Electricity Market; The Nordic Market Design - A Model For Others?; Designing Wholesale Electricity Markets: Integration with System Operations; Are the British Electricity Trading and Transmission Arrangements Future-Proof?; Session 3: Aspects of Liberalization and its Consequences for - Investments in Interconnection Capacity: Optimal investments in interconnectors and transmission capacity: Lessons from NorNed and the East-West interconnector; Transmission regulation of an integrated energy market; - Integration of Electricity Markets: The Integration of Electricity Markets in Ireland; What would be the ideal support scheme for wind power, in the context of large-scale wind integration and a regional electricity

    This research has as objective the description of information management process in the State Agency of Public Services Regulation from Mato Grosso do Sul (AGEPAN), Brazil, with focus in the strategical decision making as source of competitive intelligence in the regulation of the electric energy distribution market in the state of Mato Grosso do Sul. In the external environment it had been identified the National Agency of Electric Energy, the State Agency of Public Services Regulation from Mato Grosso do Sul, the State, the concessionaires ENERSUL and Elektro and the Society, represented by the Supervision for Consumer's Orientation and Defence (PROCON), Public Prosecution Service, Self-Regulating Body of the Engineering and Architecture Profession, Brazilian |Lawyers Association- MS, as actors in the regulation process. The played roles per item of these actors had been described. The information used by AGEPAN had been defined from the interests and necessities for taking of strategical decision according to Agency's strategical planning. The stages of the management process from these information as source of competitive intelligence in the regulation had been described for the AGEPAN decision makers, from the collection of data by interview in depth with the members of the Decision Advice of the Agency. As referential theoretician for elaboration of the script from the interviews the model of information management proposed by Choo was used. According to the decision makers interviewed, the process of management of the described information did not present evidences that could characterize the decision taking as source of competitive intelligence in the stage of the relative management to the adaptive behavior.

    Cryopreservation is the technology of choice not only for plant genetic resource preservation but also for virus eradication and for the efficient management of large-scale micropropagation. In this chapter, we describe three cryopreservation protocols (standard vitrification, droplet vitrification, and encapsulation vitrification) for date palm highly proliferating meristems that are initiated from vitro-cultures using plant growth regulator-free MS medium. The positive impact of sucrose preculture and cold hardening treatments on survival rates is significant. Regeneration rates obtained with standard vitrification, encapsulation-vitrification, and droplet-vitrification protocols can reach 30, 40, and 70%, respectively. All regenerated plants from non-cryopreserved or cryopreserved explants don't show morphological variation by maintaining genetic integrity without adverse effect of cryogenic treatment. Cryopreservation of date palm vitro-cultures enables commercial tissue culture laboratories to move to large-scale propagation from cryopreserved cell lines producing true-to-type plants after clonal field-testing trials. When comparing the cost of cryostorage and in-field conservation of date palm cultivars, tissue cryopreservation is the most cost-effective. Moreover, many of the risks linked to field conservation like erosion due to climatic, edaphic, and phytopathologic constraints are circumvented.

    2015-10-01

    The relationship between reported bullying, reported dating violence, and dating relationship quality measured through couple observations was examined. Given past research demonstrating similarity between peer and dating contexts, we expected that bullying would predict negative dating experiences. Participants with dating experience (n = 585; 238 males, M(age) = 15.06) completed self-report assessments of bullying and dating violence perpetration and victimization. One month later, 44 opposite-sex dyads (M(age) = 15.19) participated in behavioral observations. In 10-min sessions, couples were asked to rank and discuss areas of relationship conflict while being video-recorded. Qualities of the relationship were later coded by trained observers. Regression analysis revealed that bullying positively predicted dating violence perpetration and victimization. Self-reported bullying also predicted observations of lower relationship support and higher withdrawal. Age and gender interactions further qualified these findings. The bullying of boys, but not girls, was significantly related to dating violence perpetration. Age interactions showed that bullying was positively predictive of dating violence perpetration and victimization for older, but not younger adolescents. Positive affect was also negatively predicted by bullying, but only for girls. These findings add to the growing body of evidence that adolescents carry forward strategies learned in the peer context to their dating relationships. © The Author(s) 2014.

    Date palm (Phoenix dactylifera) is widely cultivated in Kutch district of Gujarat and the fruits are harvested at immature stage before the onset of monsoon to prevent spoilage. The immature date fruits with less commercial value were used for processing into date juice concentrate. Immature dates were crushed and treated with 0.1% pectinase enzyme for 120 min to obtain maximum juice. Date juice was found to be rich in reducing sugars (16.1%) and total sugars (18.3%). Juice was pasteurized at 85°C to inactivate the enzyme, cooled and centrifuged at 3000 rpm to get clear juice. The juice was concentrated in a thin film evaporator to a total soluble solids (TSS) of 76°Brix in 2 passes. Chemical composition of date juice during different stages of concentration was determined. Date juice concentrate was packed in low density polyethylene bags of size (22 cm × 14 cm) and frozen in blast freezer at -40°C and stored at -20°C. Storage of date juice concentrate at -20°C for 6 months indicated no significant changes in TSS, acidity, ascorbic acid, total sugars and pH. Hunter colour lightness L, and redness a values of date juice concentrate decreased whereas b values increased during storage. Date juice concentrate was stable during 6 months storage could be reconstituted for preparing ready-to-serve beverages with acceptable sensory quality.

  14. Regulation of the power sector

    CERN Document Server

    2013-01-01

    Regulation of the Power Sector is a unified, consistent and comprehensive treatment of the theories and practicalities of regulation in modern power-supply systems. The need for generation to occur at the time of use occasioned by the impracticality of large-scale electricity storage coupled with constant and often unpredictable changes in demand make electricity-supply systems large, dynamic and complex and their regulation a daunting task. Conceptually arranged in four parts, this book addresses both traditional regulatory frameworks and also liberalized and re-regulated environments. First, an introduction gives a full characterization of power supply including engineering, economic and regulatory viewpoints. The second part presents the fundamentals of regulation and the third looks at the regulation of particular components of the power sector in detail. Advanced topics and subjects still open or subject to dispute form the content of the fourth part. In a sector where regulatory design is the key driver...

  17. Electric Field Generation in Martian Dust Devils

    Barth, Erika L.; Farrell, William M.; Rafkin, Scot C. R.

    2015-01-01

    Terrestrial dust devils are known to generate electric fields from the vertical separation of charged dust particles. The particles present within the dust devils on Mars may also be subject to similar charging processes and so likely contribute to electric field generation there as well. However, to date, no Marsin situ instrumentation has been deployed to measure electric field strength. In order to explore the electric environment of dust devils on Mars, the triboelectric dust charging physics from the MacroscopicTriboelectric Simulation (MTS) code has been coupled to the Mars Regional Atmospheric ModelingSystem (MRAMS). Using this model, we examine how macroscopic electric fields are generated within martian dust disturbances and attempt to quantify the time evolution of the electrodynamical system.Electric fields peak for several minutes within the dust devil simulations. The magnitude of the electric field is a strong function of the size of the particles present, the average charge on the particles and the number of particles lifted. Varying these parameters results in peak electric fields between tens of millivolts per meter and tens of kilovolts per meter.

    Full Text Available Electronic cash (e-cash is definitely one of the most popular research topics in the e-commerce field. It is very important that e-cash be able to hold the anonymity and accuracy in order to preserve the privacy and rights of customers. There are two types of e-cash in general, which are online e-cash and offline e-cash. Both systems have their own pros and cons and they can be used to construct various applications. In this paper, we pioneer to propose a provably secure and efficient offline e-cash scheme with date attachability based on the blind signature technique, where expiration date and deposit date can be embedded in an e-cash simultaneously. With the help of expiration date, the bank can manage the huge database much more easily against unlimited growth, and the deposit date cannot be forged so that users are able to calculate the amount of interests they can receive in the future correctly. Furthermore, we offer security analysis and formal proofs for all essential properties of offline e-cash, which are anonymity control, unforgeability, conditional-traceability, and no-swindling.

    We develop a Bayesian Markov chain Monte Carlo (MCMC) algorithm for estimating divergence times using sequentially sampled molecular sequences. This type of data is commonly collected during viral epidemics and is sometimes available from different species in ancient DNA studies. We derive the distribution of ages of nodes in the tree under a birth-death-sequential-sampling (BDSS) model and use it as the prior for divergence times in the dating analysis. We implement the prior in the MCMCtree program in the PAML package for divergence dating. The BDSS prior is very flexible and, with different parameters, can generate trees of very different shapes, suitable for examining the sensitivity of posterior time estimates. We apply the method to a data set of SIV/HIV-2 genes in comparison with a likelihood-based dating method, and to a data set of influenza H1 genes from different hosts in comparison with the Bayesian program BEAST. We examined the impact of tree topology on time estimates and suggest that multifurcating consensus trees should be avoided in dating analysis. We found posterior time estimates for old nodes to be sensitive to the priors on times and rates and suggest that previous Bayesian dating studies may have produced overconfident estimates.

    2015-07-01

    The number eight is considered lucky in Chinese culture, e.g. the Beijing Olympics began at 8:08 pm on 8/8/2008. Given the potential for discretion in selecting particular dates of labor induction or scheduled Cesarean section (C-section), we consider whether Chinese-American births in California occur disproportionately on the 8th, 18th, or 28th day of the month. We find 2.3% "too many" Chinese births on these auspicious birth dates, whereas Whites show no corresponding increase. The increase in Chinese births is driven by higher parity C-sections: the number of repeat C-sections is 6% "too high" on auspicious birth dates. Sons born to Chinese parents account for the entire increase; daughter deliveries do not seem to be timed to achieve "lucky" birth dates. We also find avoidance of repeat C-section deliveries on the 4th, 14th, and 24th of the month, considered unlucky in Chinese culture. Finally, we replicate earlier work finding that Friday the 13th delivery dates are avoided and document a particularly large decrease among Chinese. For Whites and Chinese in California, mothers with higher levels of education are particularly likely to avoid delivering on the 13th. Copyright © 2015 Elsevier B.V. All rights reserved.

  7. Using fleets of electric-drive vehicles for grid support

    Science.gov (United States)

    Tomić, Jasna; Kempton, Willett

    Electric-drive vehicles can provide power to the electric grid when they are parked (vehicle-to-grid power). We evaluated the economic potential of two utility-owned fleets of battery-electric vehicles to provide power for a specific electricity market, regulation, in four US regional regulation services markets. The two battery-electric fleet cases are: (a) 100 Th!nk City vehicle and (b) 252 Toyota RAV4. Important variables are: (a) the market value of regulation services, (b) the power capacity (kW) of the electrical connections and wiring, and (c) the energy capacity (kWh) of the vehicle's battery. With a few exceptions when the annual market value of regulation was low, we find that vehicle-to-grid power for regulation services is profitable across all four markets analyzed. Assuming now more than current Level 2 charging infrastructure (6.6 kW) the annual net profit for the Th!nk City fleet is from US 7000 to 70,000 providing regulation down only. For the RAV4 fleet the annual net profit ranges from US 24,000 to 260,000 providing regulation down and up. Vehicle-to-grid power could provide a significant revenue stream that would improve the economics of grid-connected electric-drive vehicles and further encourage their adoption. It would also improve the stability of the electrical grid.

    There are many examples of rock surfaces, rock art and stone structures whose ages are of great importance to the understanding of various phenomena in geology, climatology and archaeology. Optically stimulated luminescence (OSL) dating is a well-established chronological tool that has successfully...... determined the depositional age of a wide variety of fine-grained sediments, from several years to several hundred thousands of years. However, there is no routine OSL dating method applicable to larger clasts such as cobbles, boulders and other rock surfaces. Here the application of quartz OSL to the dating...... of rock surfaces is successfully tested by application to two different quartz-rich rock types (sandstone and quartzite). Together with the measurement of infrared stimulated luminescence (IRSL) signals as a function of depth into the surface of different granites it is clear that both OSL and IRSL can...

    An important piece of metadata for any astronomical image is the date and time at which it was observed (and the exposure time). Unfortunately, the values of the observation epoch found in the FITS headers of digitized photographic plates, for example, are not always accurate. There can be many different sources of error: mistakes in the original observation log, errors when converting between different dates and time format (calendar date, Julian days, decimal years, etc.). We present in this paper an analysis of the different values that can be found for the observation epoch of several image sets in various metadata sources. We show how the presence of known asteroids in the field of view can be used to recover the correct time values with a good accuracy.

In addition, EVs can reduce the usage of fossil fuels in the transport sector because EVs can be charged using electricity from renewable energy sources...... on all aspects of charging EVs, including integration with the electricity prices from a spot market. The proposed data warehouse is fully implemented and currently contains 2.5 years of charging data from 176 EVs. We describe the date warehouse model and the implementation including complex operations...... such as spatially identifying charging station usage patterns. Further, we give examples of novel analyses, e.g., how the free battery capacity in the fleet of EVs changes over the day and how users can save money by charging the EVs when the electricity price is the lowest....

    In previous Annual Energy Outlooks (AEO), international electricity trade was represented in the National Energy Modeling System (NEMS) Electricity Market Module (EMM) modeling framework as an exogenous input. The exception to this exogenous treatment was for firm power projections, i.e., new Canadian hydroelectric model builds. The AEO95 implementation of EMM allowed Canadian hydroelectric projects to be selected in the Electricity Capacity Planning (ECP) submodule on an annual basis and otherwise addressed as any other purchased power commitments. This technical memorandum addresses modifications to the Electricity Fuel Dispatch Submodule implemented in AEO96 to enhance the treatment of international electricity trade through the representation of economy imports from Canada.

  20. Dating Petroglyphs from Fugoppe Cave, Japan

    2014-01-01

    Full Text Available For over 20 years, I have tried to establish a relative date for petroglyphs in Fugoppe Cave, Japan. Unsuspected amidst debris accumulating from about 1300 years ago, the petroglyphs were rediscovered accidentally in 1950. From an analysis of petroglyphs on fallen rocks scattered randomly on the site floor, I argue that the artworks date from ca.1900 years ago. The cave itself, formed by wave action, saw its main occupation by pottery-making people from 1700–1500 years ago; although the petroglyphs on the rock walls predated their occupation, it seems unlikely that the occupants attached any meaning to them.

    New absolute dates have been obtained for the Bilzingsleben (D.D.R.) archaeological site, using uranium-series analyses of travertine, and electron spin resonance (ESR) analyses of travertine and tooth enamel of rhinoceros. The results indicate that the site was apparently occupied during interglacial isotope stages 9 or 11. The surrounding terrain has been subsequently dissected by at least three discrete stages of fluvial erosion during succeeding glacial stages. Bilzingsleben is thus shown to be significantly older than the Lower Travertine at the nearby site of Ehringsdorf, assigned to isotope stage 7 by uranium-series dating. The latter assignment is confirmed by new ESR data presented here.

    This slide-show presented an overview of the Constrained Progressive Reversal (CPR) method for computing decays, age dating, and spoof detecting. The CPR method is: Capable of temporal profiling a SNM sample; Precise (compared with known decay code, such a ORIGEN); Easy (for computer implementation and analysis). We have illustrated with real SNM data using CPR for age dating and spoof detection. If SNM is pure, may use CPR to derive its age. If SNM is mixed, CPR will indicate that it is mixed or spoofed.

  4. The electric Moho.

    2001-01-18

    Since Mohorovicić discovered a dramatic increase in compressional seismic velocity at a depth of 54 km beneath the Kulpa Valley in Croatia, the 'Moho' has become arguably the most important seismological horizon in Earth owing to its role in defining the crust-mantle boundary. It is now known to be a ubiquitous feature of the Earth, being found beneath both the continents and the oceans, and is commonly assumed to separate lower-crustal mafic rocks from upper-mantle ultramafic rocks. Electromagnetic experiments conducted to date, however, have failed to detect a corresponding change in electrical conductivity at the base of the crust, although one might be expected on the basis of laboratory measurements. Here we report electromagnetic data from the Slave craton, northern Canada, which show a step-change in conductivity at Moho depths. Such resolution is possible because the Slave craton is highly anomalous, exhibiting a total crustal conductance of less than 1 Siemens--more than an order of magnitude smaller than other Archaean cratons. We also found that the conductivity of the uppermost continental mantle directly beneath the Moho is two orders of magnitude more conducting than laboratory studies on olivine would suggest, inferring that there must be a connected conducting phase.

  5. NV energy electricity storage valuation :

    Energy Technology Data Exchange (ETDEWEB)

    Ellison, James F.; Bhatnagar, Dhruv; Samaan, Nader; Jin, Chunlian

    2013-06-01

    This study examines how grid-level electricity storage may benefit the operations of NV Energy, and assesses whether those benefits are likely to justify the cost of the storage system. To determine the impact of grid-level storage, an hourly production cost model of the Nevada Balancing Authority ("BA") as projected for 2020 was created. Storage was found to add value primarily through the provision of regulating reserve. Certain storage resources were found likely to be cost-effective even without considering their capacity value, as long as their effectiveness in providing regulating reserve was taken into account. Giving fast resources credit for their ability to provide regulating reserve is reasonable, given the adoption of FERC Order 755 ("Pay-for-performance"). Using a traditional five-minute test to determine how much a resource can contribute to regulating reserve does not adequately value fast-ramping resources, as the regulating reserve these resources can provide is constrained by their installed capacity. While an approximation was made to consider the additional value provided by a fast-ramping resource, a more precise valuation requires an alternate regulating reserve methodology. Developing and modeling a new regulating reserve methodology for NV Energy was beyond the scope of this study, as was assessing the incremental value of distributed storage.

    The continuance of agricultural production in regions of the world with chronic water shortages depends upon understanding how soil salinity is impacted by irrigation practises such as water salinity, irrigation frequency and amount of irrigation. A two-year field study was conducted in a Saharan oasis of Tunisia (Lazala Oasis) to determine how the soil electrical conductivity was affected by irrigation of date palms with high saline water. The study area lacked a saline shallow water table. Field results indicate that, under current irrigation practises, soil electrical conductivity can build up to levels which exceed the salt tolerance of date palm trees. The effects of irrigation practises on the soil electrical conductivity were also evaluated using model simulations (HYDRUS-1D) of various irrigation regimes with different frequencies, different amounts of added water and different water salinities. The comparison between the simulated and observed results demonstrated that the model gave an acceptable estimation of water and salt dynamics in the soil profile, as indicated by the small values of root mean square error (RMSE) and the high values of the Nash-Sutcliffe model efficiency coefficient (NSE). The simulations demonstrated that, under field conditions without saline shallow groundwater, saline irrigation water can be used to maintain soil electrical conductivity and soil water content at safe levels (soil electrical conductivity 0.04 cm(3) cm(-3)) if frequent irrigations with small amounts of water (90 % of the evapotranspiration requirements) were applied throughout the year.

  7. Three essays on "making" electric power markets

    Science.gov (United States)

    Kench, Brian Thomas

    2000-10-01

    Technological change over the past three decades has altered most of the basic conditions in the electric power industry. Because of technical progress, the dominant paradigm has shifted from the provision of electric power by regulated and vertically integrated local natural monopolies to competition and vertical separation. In the first essay I provide a historical context of the electric industry's power current deregulation debate. Then a dynamic model of induced institutional change is used to investigate how endogenous technological advancements have induced radical institutional change in the generation and transmission segments of the electric power industry. Because the Federal Energy Regulatory Commission (FERC) ordered regulated utilities to provide open access to their transmission networks and to separate their generation and transmission functions, transmission networks have been used more intensively and in much different ways then in the past. The second essay tests experimentally the predictions of neoclassical theory for a radial electric power market under two alternative deregulated transmission institutions: financial transmission rights and physical transmission rights. Experimental evidence presented there demonstrates that an electric power market with physical transmission rights governing its transmission network generates more "right" market signals relative to a transmission network governed by financial transmission rights. The move to a greater reliance on markets for electric power is an idea that has animated sweeping and dramatic changes in the traditional business of electric power. The third essay examines two of the most innovative and complex initiatives of making electric power markets in the United States: California and PJM. As those markets mature and others are made, they must revise their governance mechanisms to eliminate rules that create inefficiency and adopt rules that work efficiently elsewhere. I argue that

  12. The False Security of Blind Dates

    Science.gov (United States)

    Cimino, J.J.

    2012-01-01

    Background The reuse of clinical data for research purposes requires methods for the protection of personal privacy. One general approach is the removal of personal identifiers from the data. A frequent part of this anonymization process is the removal of times and dates, which we refer to as “chrononymization.” While this step can make the association with identified data (such as public information or a small sample of patient information) more difficult, it comes at a cost to the usefulness of the data for research. Objectives We sought to determine whether removal of dates from common laboratory test panels offers any advantage in protecting such data from re-identification. Methods We obtained a set of results for 5.9 million laboratory panels from the National Institutes of Health’s (NIH) Biomedical Translational Research Information System (BTRIS), selected a random set of 20,000 panels from the larger source sets, and then identified all matches between the sets. Results We found that while removal of dates could hinder the re-identification of a single test result, such removal had almost no effect when entire panels were used. Conclusions Our results suggest that reliance on chrononymization provides a false sense of security for the protection of laboratory test results. As a result of this study, the NIH has chosen to rely on policy solutions, such as strong data use agreements, rather than removal of dates when reusing clinical data for research purposes.

    2013-08-01

    This is the first study on the prevalence of dating violence and threats of being forced to "come out of the closet" among Chinese gay men. Data on social demographic information and the experience of dating violence, including types of abuse, threats of "outing," and the gender of abusers were collected from 418 gay men and 330 heterosexual men by self-administered questionnaires. Mann-Whitney U test, χ(2) test, and multivariate logistic regression analyses were used to test group differences. Up to 32.8% of the gay men had experienced one abuse or more. Among those experiencing abuse, 83.9% of the gay men never told anyone about their abuse. The experience of any form of abuse by gay men was 5.07 times higher than the rate of abuse among heterosexual men controlling for age in logistic regression models. In addition, 12.4% of the gay men have experienced the threat of being outed. Overall, dating violence is more prevalent in gay men than in heterosexuals. Efforts to prevent dating violence, especially among gay men, should be made in China.

    2000-11-01

    In this study, 196 young adolescents who reported that they bullied their peers were identified out of a sample of 1,758 students in Grades 5 through 8. After selecting from the total sample a group of nonbullying youth who were matched on gender, school, and grade, a comparison was made of the groups' dating experiences, quality of friend and boyfriend or girlfriend relationships, and acts of physical and social aggression. The results indicated that bullies started dating earlier and engaged in more advanced dyadic dating than comparison adolescents. Bullies were highly relationship oriented, yet their views of their friends and boyfriends or girlfriends were less positive and less equitable than the comparison adolescents. Finally, bullies were more likely to report physical and social aggression with their boyfriends or girlfriends. Although the bullies reported more advanced pubertal development, this factor did not fully account for their dating precocity and negative romantic relationships. The results confirmed our hypotheses that adolescents whose peer relationships are characterized by bullying are at risk in their development of healthy romantic relationships.

  16. ESR dating of the fault rocks

    Energy Technology Data Exchange (ETDEWEB)

    Lee, Hee Kwon [Kangwon National Univ., Chuncheon (Korea, Republic of)

    2004-01-15

    Past movement on faults can be dated by measurement of the intensity of ESR signals in quartz. These signals are reset by local lattice deformation and local frictional heating on grain contacts at the time of fault movement. The ESR signals then grow back as a result of bombardment by ionizing radiation from surrounding rocks. The age is obtained from the ratio of the equivalent dose, needed to produce the observed signal, to the dose rate. Fine grains are more completely reset during faulting, and a plot of age vs, grain size shows a plateau for grains below critical size : these grains are presumed to have been completely zeroed by the last fault activity. We carried out ESR dating of fault rocks collected near the Ulzin nuclear reactor. ESR signals of quartz grains separated from fault rocks collected from the E-W trend fault are saturated. This indicates that the last movement of these faults had occurred before the quaternary period. ESR dates from the NW trend faults range from 300ka to 700ka. On the other hand, ESR date of the NS trend fault is about 50ka. Results of this research suggest that long-term cyclic fault activity near the Ulzin nuclear reactor continued into the pleistocene.

    2016-01-01

    Dates are a concentrated source of essential nutrients, vitamins, minerals, and carbohydrates (CHOs), which are necessary for the maintenance of optimum health. Most of the CHOs in dates come from sugars including glucose and fructose. Dates are commonly consumed in Saudi Arabia, particularly at the time of breaking the fast to provide instant energy and maintain blood sugar level. However, dates may cause hypoglycemia in a rare condition named as heredity fructose intolerance (HFI), and a few families have been to see us with a history of that nature. This is to report the preliminary results of an on-going study of a group of patients who get symptoms of hypoglycemia following the ingestion of dates and have suffered for years without an accurate diagnosis. This report is based on three patients, from the same family, living in a date growing region of the Kingdom of Saudi Arabia (KSA). The patients had been to several medical centers without getting any definite answers or diagnosis until they were referred to the Gastroenterology Clinic of King Fahd Hospital of the University, Al-Khobar, KSA. The data were obtained by careful history and laboratory investigations, and a final diagnosis of HFI made on fructose intolerance test (FIT). The patients reported that they had avoided eating dates because of various symptoms, such as bloating, nausea, and even hypoglycemia when larger amounts were consumed. Their other symptoms included sleepiness, sweating, and shivering. After full examinations and necessary laboratory tests based on the above symptoms, FIT was performed and the patients were diagnosed with HFI. They were referred to a dietitian who advised a fructose-free diet. They felt well and were free of symptoms. HFI may remain undiagnosed until adulthood and may lead to disastrous complications and even death. The diagnosis can only be suspected after a careful dietary history is taken supported by FIT. This can prevent serious complications. Restricting

    2017-06-28

    The primary aims of this study were to test whether perceived dating success would differ between offline and online zero-acquaintance dating contexts and to investigate the role that self-esteem might play in these evaluations. Participants were presented with the same photos of targets in either an offline or online dating scenario and rated their chances of dating success along with their perceptions of how attractive they thought the target would consider them. Higher self-esteem individuals believed they would be rated as more attractive. There was an overall perception that, irrespective of self-esteem level, meeting online would lead to better chances of dating success. These findings are considered in relation to an increased ability to more precisely manage impressions and develop an image of the self which would be evaluated more positively online.

  9. Internet dating as a project: the commodification and rationalisation of online dating

    Directory of Open Access Journals (Sweden)

    Tjaša Žakelj

    2015-04-01

    Full Text Available Based on qualitative empirical data from two studies on Internet dating in Slovenia, this paper discusses the social contexts of the Internet dating of heterosexual men and women and homosexual men. Special attention is given to different aspects of the commodification and rationalisation of dating in the process of forming potential (romantic partnerships. First, we discuss our respondents’ reasons for using the Internet to get in touch with potential (romantic partners. Second, we focus on the demands and strategies of targeted market- ing in personal profile writing and, finally, on the process of selecting potential partners. Our study shows that the primary understanding of Internet dating among people who engage in it is its economic nature. Together with targeted marketing and the predeter- mined criteria for choosing interesting others, Internet dating can thus be understood as a market that encourages rationalisation and commodification in the process of forming intimate relationships.

    We examined the association between witnessing interparental violence, attitudes about dating violence, and physical and psychological teen dating violence (TDV) victimization. Participants were 918 teens with dating experience. Witnessing interparental violence and acceptance of dating violence were significant predictors of TDV victimization. Acceptance of dating violence was also a partial mediator between witnessing interparental violence and TDV victimization. Witnessing mother-to-father violence and acceptance of female-perpetrated violence were the most consistent predictors. TDV programs aiming to prevent victimization could benefit from targeting youth exposed to father-to-mother and mother-to-father violence, targeting attitudes about violence, and tailoring interventions to gender-specific risk factors. © The Author(s) 2015.

    Electrical injuries in swimming pools are an important pediatric public health concern. We sought to (1) improve our understanding of the clinical presentation and outcomes following and (2) describe the epidemiology of swimming pool electrical injuries in the United States. We reviewed 4 cases of pediatric (public (23.9%) and sports facilities (19.1%). Electrical outlets or receptacles (39.8%) were most commonly implicated, followed by electrical system doors (18.2%), electric wiring systems (17.0%), thermostats (16.3%), hair dryers (4.6%), and radios (4.1%). Pediatric cases represented 48.4% of swimming pool-related electrical injuries reported to NEISS. Electrical injuries occurring in and around swimming pools remain an important source of morbidity and mortality. Although NEISS monitors sentinel events, current efforts at preventing such cases are less than adequate. All electrical outlets near swimming pools should be properly wired with ground fault circuit interrupter devices. Possible approaches to increasing safe electrical device installation are through strengthening public awareness and education of the potential for injury, as well as changes to current inspection regulations.

    Keltgen, James

    New innovations and technologies using unmanned aerial systems (UAS), or drones, have created unique opportunities for commercial applications. Electric utilities, likewise, realize the benefits of using UAS as a tool in electric utility operations. Although the opportunities exist, establishing a UAS program for electric utilities is largely an endeavor of trial and error or research and development with no clear path defined on how to establish a UAS program. By reviewing UAS use case examples and integrating lessons learned with Federal Aviation Administration (FAA) regulations, UAS best practices, unique electric utility values, legal and insurance perspectives, equipment selection, and thoughtful planning and preparation; a solution model is developed to establish a UAS program for electric utilities.

    Nuclear regulation and safety are discussed from the standpoint of a hypothetical country that is in the process of introducing a nuclear power industry and setting up a regulatory system. The national policy is assumed to be in favor of nuclear power. The regulators will have responsibility for economic, reliable electric production as well as for safety. Reactor safety is divided into three parts: shut it down, keep it covered, take out the afterheat. Emergency plans also have to be provided. Ways of keeping the core covered with water are discussed.

    The first book studies on the economics of electricity consumption. Compares the sector production functions with electricity and the commercial production functions with electricity. Introduces the global E-GDP function, the European E-GDP function and 12 national E-GDP functions. Presents the gene characters of EAI production functions and E-GDP functions for USA to see why USA's economy is entering an up-industrialization period. Discusses China's economic growth by production functions with electricity. Electricity Economics: Production Functions with Electricity studies the production output from analyzing patterns of electricity consumption. Since electricity data can be used to measure scenarios of economic performance due to its accuracy and reliability, it could therefore also be used to help scholars explore new research frontiers that directly and indirectly benefits human society. Our research initially explores a similar pattern to substitute the Cobb-Douglas function with the production function with electricity to track and forecast economic activities. The book systematically introduces the theoretical frameworks and mathematical models of economics from the perspective of electricity consumption. The E-GDP functions are presented for case studies of more than 20 developed and developing countries. These functions also demonstrate substantial similarities between human DNA and production functions with electricity in terms of four major characteristics, namely replication, mutation, uniqueness, and evolution. Furthermore, the book includes extensive data and case studies on the U.S., China, Japan, etc. It is intended for scientists, engineers, financial professionals, policy makers, consultants, and anyone else with a desire to study electricity economics as well as related applications.

    The work was aimed for the ascertainment of following question - whether Orexin-containing neurons of dorsal and lateral hypothalamic, and brain Orexinergic system in general, are those cellular targets which can speed up recovery of disturbed sleep homeostasis and accelerate restoration of sleep-wakefulness cycle phases during some pathological conditions - experimental comatose state and/or deep anesthesia-induced sleep. Study was carried out on white rats. Modeling of experimental comatose state was made by midbrain cytotoxic lesions at intra-collicular level.Animals were under artificial respiration and special care. Different doses of Sodium Ethaminal were used for deep anesthesia. 30 min after comatose state and/or deep anesthesia induced sleep serial electrical stimulations of posterior and/or perifornical hypothalamus were started. Stimulation period lasted for 1 hour with the 5 min intervals between subsequent stimulations applied by turn to the left and right side hypothalamic parts.EEG registration of cortical and hippocampal electrical activity was started immediately after experimental comatose state and deep anesthesia induced sleep and continued continuously during 72 hour. According to obtained new evidences, serial electrical stimulations of posterior and perifornical hypothalamic Orexin-containing neurons significantly accelerate recovery of sleep homeostasis, disturbed because of comatose state and/or deep anesthesia induced sleep. Speed up recovery of sleep homeostasis was manifested in acceleration of coming out from comatose state and deep anesthesia induced sleep and significant early restoration of sleep-wakefulness cycle behavioral states.

    Full Text Available The aim of the study is to analyze the youngest in the world competitive market of electric energy and power of Russia. The hypothesis that there is a significant time lag between the launch date regulated competitive energy market and the actual state of its transition to a stationary operation. To test the hypothesis covered the electric energy consumer’s reaction on tariffs changes in the UES of the Ural in the period of time after restructuring RJSC “UES of Russian Federation”. Factual data of UES of Russia’s System operator shows how indicator values of electric energy consumption elasticity changes: consuming turns from elastic to inelastic according to price. Proved that in 2014 the energy demand matches to a competitive market. As a methodical research tool used 5 types of regression analysis equations for time series of electricity consumption, in addiction by the rate of the day-ahead market for 2009-2014. The research found that the transition to a competitive market of electricity production in Russia in fact was didn’t carried out in 2008, but was carried in 2014. Research proved that the electricity market regression analysis applied in predicting short periods of time (day-ahead market, because by increasing the time interval of forecasting accuracy of the forecast is decreases. The research results have great practical significance for the power industry subjects, especially those with high energy intensity of production, as the increase in the accuracy of forecasting reduces fines and total costs for electricity.

    The electricity markets in the Nordic countries have undergone major changes since the electricity market reform work was started in the early 1990s. Sweden, Norway and Finland have had a common electricity market since 1996. The work of also reforming the Danish electricity market was begun in the year 2000. The objective of the electricity market reform is to introduce increased competition, to give the consumers greater freedom of choice and also, by open and expanded trade in electricity, create the conditions for efficient pricing. The Swedish National Energy Administration is the supervisory authority as specified in the Electricity Act, and one of the tasks entrusted to it by the Government is to follow developments on the electricity market and to regularly compile and report current market information. The purpose of the 'Electricity market 2001' publication is to meet the need for generalized and readily accessible information on the conditions on the Nordic market. Iceland is not included in the description. The publication also includes summaries of information from recent years concerning electricity generation and utilization in the Nordic countries, the structure of the electricity market from the players' perspective, trade in electricity in the Nordic countries and in Northern Europe, electricity prices in the Nordic and other countries, and the impact of the electricity sector on the environment. The publication contains data on electricity generation and use during the past years, structure of the electricity market, trade in electricity in the Nordic countries and northern Europe, electricity prices in the Nordic countries and other countries as well as impact of electricity generation system on the environment.

  10. Should precise numerical dating overrule glacial geomorphology?

    Science.gov (United States)

    Winkler, Stefan

    2016-04-01

    Numerical age dating techniques, namely different types of terrestrial cosmogenic nuclide dating (TCND), have achieved an impressive progress in both laboratory precision and regional calibration models during the past few decades. It is now possible to apply precise TCND even to young landforms like Late Holocene moraines, a task seemed hardly achievable just about 15 years ago. An increasing number of studies provide very precise TCND ages for boulders from Late Holocene moraines enabling related reconstruction of glacier chronologies and the interpretation of these glacial landforms in a palaeoclimatological context. These studies may also solve previous controversies about different ages assigned to moraines obtained by different dating techniques, for example relative-age dating techniques or techniques combining relative-age dating with few fixed points derived from numerical age dating. There are a few cases, for example Mueller Glacier and nearby long debris-covered valley glacier in Aoraki/Mt.Cook National Park (Southern Alps, New Zealand), where the apparent "supremacy" of TCND-ages seem to overrule glacial geomorphological principles. Enabled by a comparatively high number of individual boulders precisely dated by TCND, moraine ridges on those glacier forelands have been primarily clustered on basis of these boulder ages rather than on their corresponding morphological position. To the extreme, segments of a particular moraine complex morphologically and sedimentologically proven to be formed during one event have become split and classified as two separate "moraines" on different parts of the glacier foreland. One ledge of another moraine complex contains 2 TCND-sampled boulders apparently representing two separate "moraines"-clusters of an age difference in the order of 1,500 years. Although recently criticism has been raised regarding the non-contested application of the arithmetic mean for calculation of TCND-ages for individual moraines, this

    The biggest island in South Korea is Jeju Island, which lies 80 km south of the mainland and has one shield volcano, Mt. Halla. The volcanic island and its lava tubes were added to the world heritage list by UNESCO in 2007. Among the many lava tubes on the island, a unique cave had been accidentally found in 2005 while some workers were replacing a telephone pole. Until the discovery, it had been completely isolated from the outside by naturally-built sand blocks. Yongcheon cave is a lime-decorated lava tube showing both the properties of a volcanic lava tube and a limestone cave. This cave, about 3 km in length, is acknowledged to be the best of this type in the world and includes a large clean-water lake, lava falls, and richly developed speleothems inside it. Even though there is archaeological evidence from well preserved pottery that ancient people entered this place, the preservation of artifacts was ensured by a geological change that made later entrance difficult. We have collected charcoal samples scattered around the cave and dated them using AMS. Ages were in the range of ca. 1570-1260 BP (A.D. 340-880) and this corresponds to the Ancient Three Kingdoms and the Unified Silla era in Korean history. The {sup 14}C AMS measurement results presented in this paper on wood charcoal provide precise dates which will be very useful not only to clarify the nature of human activities in this cave but also to provide reference dates when comparing other dating methods.

    This study explores factors that influence matches of online dating participants' stated preference for particular characteristics in a potential partner and compares these with the characteristics of the online daters actually contacted. The nature of online dating facilitates exploration of the differences between stated preference and actual choice by participants, as online daters willingly provide a range of demographics on their ideal partner. Using data from the Australian dating website RSVP, we analyze 219,013 contact decisions. We conduct a multivariate analysis using the number of matched variables between the participants' stated preference and the characteristics of the individuals contacted. We find that factors such as a person's age, their education level, and a more social personality all increase the number of factors they choose in a potential partner that match their original stated preference. Males (relative to females) appear to match fewer characteristics when contacting potential love interests. Conversely, age interaction effects demonstrate that males in their late 60's are increasingly more selective (than females) regarding who they contact. An understanding of how technology (the Internet) is impacting human mating patterns and the psychology behind the participants informs the wider social science of human behavior in large-scale decision settings.

    Mezmaiskaya Cave has yielded more than 10,000 artifacts, thousands of very well preserved faunal remains, and hominin remains, found in seven Middle Paleolithic (Mousterian) and three Upper Paleolithic levels. A complete Neanderthal infant skeleton was preserved in anatomical juxtaposition lying on a large limestone block, overlain by the earliest Mousterian layer, Layer 3. Twenty-four skull fragments from a 1-2 year-old Neanderthal infant, showing post-mortem deformation, occurred in a pit originating in the Mousterian Layer 2 and penetrating into underlying layers 2A and 2B(1). Bone from Layer 2A was dated by AMS {sup 14}C at 35.8-36.3{+-}0.5 kyr BP. Direct dating of Neanderthal bone from Layer 3 gave an age of 29 kyr, but that is now considered to be due to contamination by modern carbon. Fourteen large mammal teeth from Layers 2 through 3 have been dated by standard electron spin resonance (ESR). Low U concentrations in both the enamel and dentine ensure that ESR ages do not depend significantly on the U uptake model, but do depend strongly on the sedimentary dose rates. Assuming a sedimentary water concentration equal to 20 wt%, ESR ages for the Mousterian layers range from 36.2 to 73.0{+-}5.0 ka.

  19. Workshop on dating old ground water

    Energy Technology Data Exchange (ETDEWEB)

    1978-01-01

    A workshop on methods which might be used to date very old ground water was held on March 16--18, 1978, in Tucson, Arizona. The workshop was sponsored by the Office of Waste Isolation of Union Carbide Corporation as part of studies supported by the United States Department of Energy which are designed to evaluate the safety of proposed subsurface repositories for nuclear waste. The workshop was convened by the College of Earth Sciences of the University of Arizona with the cooperation of other university departments, particularly the Department of Physics. The dating of ground water in the vicinity of nuclear repositories is a critical aspect of the safety evaluation of these repositories. The age of the water gives an indication of past rates of water movement which in turn will help evaluate the likelihood of future migration of radionuclides from a given repository. Despite this rather obvious practical application, most of the workshop time was devoted to difficult technical questions related to the actual dating of the water.

  20. Predictors of dating violence: a multivariate analysis.

    1992-01-01

    A multivariate approach was used to determine the pattern of predictors associated with engaging in dating violence. Predictors were selected whose relationship to dating violence has been established by earlier research: attitudes toward violence, sex-role attitudes, romantic jealousy, general levels of interpersonal aggression, verbal aggression, and verbal and physical aggression received from one's partner. Participants included 305 introductory psychology student volunteers (227 females and 78 males) who completed a set of scales related to dating relationships. Expecting different patterns of predictors to emerge for men and women, we performed separate multiple regression analyses for each. Of the set of predictors employed, receipt of physical violence from one's partner emerged as the largest predictor of expressed violence for both men and women. In addition, higher scores on attitudes toward violence and verbal aggression, and less traditional sex-role attitudes emerged as significant predictors of expressed violence for men. For women, less accepting attitudes toward violence, more traditional sex-role attitudes, feelings of romantic jealousy, higher general levels of interpersonal aggression, and verbal aggression were predictive of expressed violence. The implications of our findings for future research are discussed.
