    To understand the cross-talk and specificity of the early responses of plants to salt and drought, we performed physiological and proteome analyses of Brassica napus seedlings pretreated with 245 mM NaCl or 25% polyethylene glycol (PEG) 6000 under identical osmotic pressure (-1.0 MPa). Significant decreases in water content and photosynthetic rate and excessive accumulation of compatible osmolytes and oxidative damage were observed in response to both stresses. Unexpectedly, the drought response was more severe than the salt response. We further identified 45 common differentially expressed proteins (DEPs), 143 salt-specific DEPs and 160 drought-specific DEPs by isobaric tags for relative and absolute quantitation (iTRAQ) analysis. The proteome quantitative data were then confirmed by multiple reaction monitoring (MRM). The differences in the proteomic profiles between drought-treated and salt-treated seedlings exceeded the similarities in the early stress responses. Signal perception and transduction, transport and membrane trafficking, and photosynthesis-related proteins were enriched as part of the molecular cross-talk and specificity mechanism in the early responses to the two abiotic stresses. The Ca2+ signaling, G protein-related signaling, 14-3-3 signaling pathway and phosphorylation cascades were the common signal transduction pathways shared by both salt and drought stress responses; however, the proteins with executive functions varied. These results indicate functional specialization of family proteins in response to different stresses, i.e., CDPK21, TPR, and CTR1 specific to phosphorylation cascades under early salt stress, whereas STN7 and BSL were specific to phosphorylation cascades under early drought stress. Only the calcium-binding EF-hand family protein and ZKT were clearly identified as signaling proteins that acted as cross-talk nodes for salt and drought signaling pathways. Our study provides new clues and insights for developing strategies to

    Brassinosteroids (BRs) are steroid plant hormones that have been shown to be involved in the response to salt stress in cross-talk with other plant growth regulators such as polyamines (PAs). In addition, BRs are involved in the regulation of the nodulation in the rhizobium-legume symbiosis through the alteration of the PAs content in leaves. In this work, we have studied the effect of exogenous 24-epibrassinolide (EBL) in the response to salinity of nitrogen fixation in the symbiosis Medicago truncatula-Sinorhizobium meliloti. Foliar spraying of EBL restored the growth of plants subjected to salt stress and provoked an increment of the nitrogenase activity. In general, PAs levels in leaves and nodules decreased by the salt and EBL treatments, however, the co-treatment with NaCl and EBL augmented the foliar spermine (Spm) concentration. This increment of the Spm levels was followed by a reduction of the membrane oxidative damage and a diminution of the proline accumulation. The effect of BRs on the symbiotic interaction was evaluated by the addition of 0.01, 0.1 and 0.5 μM EBL to the growing solution, which provoked a reduction of the nodule number and an increment of the PAs levels in shoot. In conclusion, foliar treatment with EBL had a protective effect against salt stress in the M. truncatula-S. meliloti symbiosis mediated by an increment of the Spm levels. Treatment of roots with EBL incremented PAs levels in shoot and reduced the nodule number which suggests a cross-talk between PAs and BRs in the nodule suppression and the protection against salt stress.

    A standard way to realize communication in microgrid control is to use an external communication network, such as modems for wireless or power-line communication, whose implementation may be inefficient in terms of deployment cost, complexity, and system stability. In this chapter we present...... a communication solution, denoted as power talk, which is solely based on the use of the existing microgrid power equipment (i.e., power electronics and buses). The pivotal idea is to modulate information in the power-related parameters of the microgrid buses by use of the flexibility of power electronic...... interfaces. The focus of the chapter is on the design of power talk solutions for DC microgrids with droop control. Specifically, the chapter presents the power talk implementation through modification of the droop parameters of the primary control loop, and investigates the design of modulation schemes...

    1986-09-01

    Full Text Available This essay investigates the fragile intersection where rumor and a more "authentic" modality of language can be shown to cross over into one another. Treating the relationship of Benjamin, Heidegger and Rousseau to rumoro-logical paranoia, "Street-Talk" interprets the epistemological teetering between the knowing and not-knowing around which Fama articulates her power. All three of these thinkers are shown to be exemplarily afflicted by rumorous utterances and share a drive to create, in their works, a rumor control center. Often these controls take over the features which they attempt to disown; thus the greatest moment of truth-telling appropriates the form of inferential small-talk. The essay analyzes a temporality of writing disclosed by Rousseau's Promenades in terms of an après-ma-mort structure. Finally, guided by Blanchot's insights and Huet's notion of monsterized publicity, the essay addresses the rapport of rumor to oeuvre: Ecce Fama .

    We introduce a novel communication strategy for DC Micro Grids (MGs), termed power talk, in which the devices communicate by modulating the power levels in the DC bus. The information is transmitted by varying the parameters that the MG units use to control the level of the common bus voltage......, while it is received by processing the bus measurements that units perform. This implies that the communication does not require a dedicated modem, but instead it is piggybacked on top of the power electronics. The communication is challenged by the random fluctuations of the voltage level due...

    In this paper, a novel communication strategy called Power Talk is introduced to realize the power line communication among the Voltage Source Converters (VSC) of DC MicroGrids (MGs). Each VSC transmits information by changing the control parameters, and receives information by observing the local...... output power. By using common coding schemes, which transform the DC MGs in some familiar communication channels, some important communication challenges can be addressed, such as random load variations and VSCs switching, as it do not need a separate communication channel.

    Full Text Available The poem Small talk conjures up a communicative situation in which the main character, a newcomer from Poland, answers conventional questions related to their country. Bearing in mind the fact that this poem is set during a military dictatorship, superficial interest in his homeland may trigger a feeling of impatience. This is at least the impression formed if we adopt the perspective defined within the romantic tradition, and when taking into account the conventional poetry of martial law in Poland. Nevertheless, Barańczak retains an ironic distance towards such communicative situations and, as a consequence, does not create poetry that meets most readersʼ expectations. His poetic imperative for verbal art to be the expression of mistrust remains valid.

    Directory of Open Access Journals (Sweden)

    Johann-Albrecht Meylahn

    2015-03-01

    Full Text Available Maybe, before we speak of time, or maybe whilst we are speaking of time, or maybe after we have spoken of time, in the various modes of time’s insistence to exist, one should give time to the talk of time. There are various different modes of time’s insistence to exist, such as quantum physics in conversation with relativity theory where time is constructed as a fourth dimension of space. Or there are the modes of time in history, religion, psychology and philosophy, and each of these modes is composed, and composes its own specific object called time, and a particular subject who understands and interprets time in that particular mode. Yet, before, whilst or after these modes of time’s insistence to exist, one should maybe give time to time’s time. Give time for the various times to articulate themselves in the various modes of existence, thereby creating both a whole plurality of differing subjects, as well as plurality of differing objects, all called ‘time’. Once time has been given time to talk its talk, to articulate itself within the various modes, it will be interrupted by the articulations of time in various modes of time still to come. These disruptions of time by time always still to come opens the door for a theological narrative – a narrative on time, but created by the coming of messianic times, interpreted in the mode of hope but also in the mode of a promise from the past.

    Taking as its starting point the Nordic cultural policy debates surrounding audience development, which concentrate either on reaching out to new target groups or on artistic quality, this article suggests that the focus on the audience’s experience of theatre performances has thus far been...... underdeveloped. Through qualitative audience investigations, this article shows how talking about theatre offers a method by which to explore theatre experiences from an audience perspective, and thus provides invaluable knowledge for theatres and cultural politicians in search of larger and broader audiences...

    2007-01-01

    The aim of this paper is to shed light on euphemism in two different senses: sweet talking and deception. I shall treat euphemism from two different perspectives: the usual use of euphemism, sweet talking, in which it is used to maintain one's face and the orthophemistic sense, deception, where 'torture' is referred to as "enhanced interrogation techniques". I shall analyze examples, taken from religious, cultural, political backgrounds, on each case. Moreover, I shall talk about taboo since ...

    2017-01-01

    The interest in teachers’ discourses and vocabularies has for a long time been studied under the rubric of knowledge, most notably teachers’ professional knowledge. This interest can be traced back to Shulman’s distinction between different kinds of teacher knowledge and Schwab’s interest...... in the role of practical reasoning and judgement in teaching. Within the research, a distinction can be found between a more narrow approach that focuses on teachers’ propositional or theoretical knowledge and a more encompassing approach in which teachers’ knowledge is not only the knowledge for teachers...... generated elsewhere, but also the knowledge of teachers. This is the ‘stock of knowledge’ gained from a range of sources and experiences, including teachers’ ongoing engagement with the practice of teaching itself. In this paper, we focus on the role of teachers’ talk in their achievement of agency. We...

  16. Is talking to yourself thinking?

    Science.gov (United States)

    Rachlin, Howard

    2017-08-03

    The question whether talking to yourself is thinking is considered from two viewpoints: radical behaviorism and teleological behaviorism. For radical behaviorism, following Skinner (1945), mental events such as 'thinking' may be explained in terms of private behavior occurring within the body, ordinarily unobservable by other people; thus, radical behaviorism may identify talking to yourself with thinking. However, to be consistent with its basic principles, radical behaviorism must hold that private behavior, hence thinking, is identical with covert muscular, speech movements (rather than proprioception of those movements). For teleological behaviorism, following Skinner (1938), all mental terms, including 'thinking,' stand for abstract, temporally extended patterns of overt behavior. Thus, for teleological behaviorism, talking to yourself, covert by definition, cannot be thinking. © 2017 Society for the Experimental Analysis of Behavior.

  15. Thermodynamics of salt-doped polymers

    Science.gov (United States)

    Wang, Zhen-Gang

    2013-03-01

    There is much current interest in salt-doped polymers as materials for energy applications. For example, a promising system for rechargeable battery applications consists of diblock copolymers of an ion-dissolving block, such as polyethylene oxide (PEO) and a nonconducting block such as polystyrene. Experimentally, it has been shown that the addition of lithium salts significantly alters the order-order and order-disorder transition (ODT) temperatures. In particular, the ODT temperature can increase substantially upon adding even a small amount of lithium salt, and the domain spacing in the ordered phases also increases significantly. Both changes are found to depend on the anion type. In this talk, I describe a simple theory for explaining these phenomena. A key effect is the solvation energy of the anions by the polymers, which we approximate using the Born solvation model. The difference in the Born energy between different polymers provides a driving force towards phase separation. By studying the shift in the mean-field spinodal of the disordered phase, we can identify an effective χ parameter, with a systematic dependence on the anion radius, in agreement with available experimental data. Furthermore, by studying the behavior of the domain spacing with salt concentration, we clarify the relationship between different definitions of the effective χ parameter. We propose that the effective χ parameter determined from the structure factor of the disordered phase is a more robust measure of the change in miscibility between the two blocks. Finally, we demonstrate that salt doping induces a strongly first-order transition from the disordered phase to the lamellar phase, with different salt concentrations in the two phases.

    In this paper we discuss a particular perspective on interactivity and sociability in the design of new TV technologies for social interaction. We will argue that current research on Social TV builds on a too narrow conception of interaction in everyday social life. In consequence, rather than...... on a moment-to-moment basis throughout everyday life beyond the TV screens. We take the phenomenon of ticket-to-talk as our point of departure when analyzing observations made during a study of the ways senior citizens go about socializing in everyday face-to-face situations. We then discuss how this analysis...... turning the TV media itself into an arena for peer-to-peer synchronous interaction amongst TV viewers we will discuss the idea of Social TV as a resource that when part of a larger socio-material fabric can help accommodate the circumstantial nature of social interactions as they emerge and play out...

  3. Submarine Salt Karst Terrains

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Karst terrains that develop in bodies of rock salt (taken as mainly of halite, NaCl are special not only for developing in one of the most soluble of all rocks, but also for developing in one of the weakest rocks. Salt is so weak that many surface-piercing salt diapirs extrude slow fountains of salt that that gravity spread downslope over deserts on land and over sea floors. Salt fountains in the deserts of Iran are usually so dry that they flow at only a few cm/yr but the few rain storms a decade so soak and weaken them that they surge at dm/day for a few days. We illustrate the only case where the rates at which different parts of one of the many tens of subaerial salt karst terrains in Iran flows downslope constrains the rates at which its subaerial salt karst terrains form. Normal seawater is only 10% saturated in NaCl. It should therefore be sufficiently aggressive to erode karst terrains into exposures of salt on the thousands of known submarine salt extrusions that have flowed or are still flowing over the floors of hundreds of submarine basins worldwide. However, we know of no attempt to constrain the processes that form submarine salt karst terrains on any of these of submarine salt extrusions. As on land, many potential submarine karst terrains are cloaked by clastic and pelagic sediments that are often hundreds of m thick. Nevertheless, detailed geophysical and bathymetric surveys have already mapped likely submarine salt karst terrains in at least the Gulf of Mexico, and the Red Sea. New images of these two areas are offered as clear evidence of submarine salt dissolution due to sinking or rising aggressive fluids. We suggest that repeated 3D surveys of distinctive features (± fixed seismic reflectors of such terrains could measure any downslope salt flow and thus offer an exceptional opportunity to constrain the rates at which submarine salt karst terrains develop. Such rates are of interest to all salt tectonicians and the many

  5. Talk talk talk …’ Virginia Woolf, Ireland and Maria Edgeworth

    Directory of Open Access Journals (Sweden)

    Paul E. H. Davis

    2006-03-01

    Full Text Available This article considers Woolf’s only visit to Ireland and her attitude to the country as revealed in her diary and in a review of a book about Maria Edgeworth. She considered the fault of the Irish to be their loquaciousness. Her diary reveals her belief that Irish literature had declined since Dean Swift. Woolf, both in her twenties and when she visited Ireland in 1934, revealed a certain antipathy to the country. She asserted, for example, that the Irish propensity to talk had prevented the production of literature of any quality after the eighteenth century. In the 1909 review, Woolf, while criticising the author of a book about Maria Edgeworth, attacks Edgeworth herself. But her words imply that she had not read Maria’s Irish novels. Bloomsbury’s ‘snobbery’ and Woolf’s Feminism throughout the essay are evident in her implicit criticism of the way that Edgeworth sacrificed love for duty. In dismissing Edgeworth’s achievement, Woolf betrays a degree of ignorance that is worth considering.

    2008-02-01

    Full Text Available Sixteen 4 to 6-year-old Danish children were video-recorded, while interacting spontaneously with their family in their homes. The mental state talk of the children was identified and analysed with respect to three mental domains: desire, feeling and cognition, and was compared to data from a similar study carried out with Canadian families (Jenkins et al., 2003. Our results suggest some cross-cultural differences in children’s mental state talk. First, Danish children produce a larger variation of mental state talk words than Canadian children do, and second, the distribution of mental state talk across the three domains differed for the two language groups. Semantic variation between Danish and English was identified in the study, which may partly explain the findings. Furthermore we present a usage-based approach to the investigation of children’s development of psychological categories in language as well as cross-linguistically.

    Science.gov (United States)

    Engeln, Renee; Sladek, Michael R; Waldron, Heather

    2013-06-01

    Though researchers are beginning to examine body-related talk in women (often referred to as fat talk), little work has examined how men talk about their bodies with peers. The two studies presented in this article explore body talk among U.S. college men. First, an online survey examined the frequency with which college men engage in negative body talk, the content of these conversations, and the body image variables associated with engaging in this type of talk. Negative body talk in men was associated with drive for muscularity, eating disordered behavior, and appearance investment. Study 2 experimentally examined the effects of hearing male peers engage in negative body talk. Hearing muscle talk or fat talk caused decreased state appearance self-esteem and increased state body dissatisfaction. The correlates and consequences of negative body talk among men appear no less troubling than those identified among women. Copyright © 2013 Elsevier Ltd. All rights reserved.

  14. Resedimented salt deposits

    Energy Technology Data Exchange (ETDEWEB)

    Slaczka, A.; Kolasa, K. (Jagiellonian Univ., Krakow (Poland))

    1988-08-01

    Carparthian foredeep's Wieliczka salt mine, unique gravity deposits were lately distinguished. They are mainly built of salt particles and blocks with a small admixture of fragments of Miocene marls and Carpathian rocks, deposited on precipitated salt. The pattern of sediment distribution is similar to a submarine fan. Gravels are dominant in the upper part and sands in lower levels, creating a series of lobes. Coarse-grained deposits are represented by disorganized, self-supported conglomerates passing into matrix-supported ones, locally with gradation, and pebbly sandstones consisting of salt grains and scattered boulder-size clasts. The latter may show in the upper part of a single bed as indistinct cross-bedding and parallel lamination. These sediments are interpreted as debris-flow and high-density turbidity current deposits. Salt sandstones (saltstones) which build a lower part of the fan often show Bouma sequences and are interpreted as turbidity-current deposits. The fan deposits are covered by a thick series of debrites (olistostromes) which consist of clay matrix with salt grains and boulders. The latter as represented by huge (up to 100,000 m{sup 3}) salt blocks, fragments of Miocene marls and Carpathian rocks. These salt debrites represent slumps and debris-flow deposits. The material for resedimented deposits was derived from the southern part of the salt basin and from the adjacent, advancing Carpathian orogen. The authors believe the distinct coarsening-upward sequence of the series is the result of progressive intensification of tectonic movements with paroxysm during the sedimentation of salt debrites (about 15 Ma).

    To identify individual therapist behaviors which elicit client change talk or sustain talk in motivational interviewing sessions. Motivational interviewing sessions from a single-session alcohol intervention delivered to college students were audio-taped, transcribed, and coded using the Motivational Interviewing Skill Code (MISC), a therapy process coding system. Participants included 92 college students and eight therapists who provided their treatment. The MISC was used to code 17 therapist behaviors related to the use of motivational interviewing, and client language reflecting movement toward behavior change (change talk), away from behavior change (sustain talk), or unrelated to the target behavior (follow/neutral). Client change talk was significantly more likely to immediately follow individual therapist behaviors [affirm (p=.013), open question (pquestion (pquestions (pquestions (p<.001). Certain individual therapist behaviors within motivational interviewing can either elicit both client change talk and sustain talk or suppress both types of client language. Affirm was the only therapist behavior that both increased change talk and also reduced sustain talk. Copyright © 2015 Elsevier Inc. All rights reserved.

  20. Talking Cure Models: A Framework of Analysis.

    Science.gov (United States)

    Marx, Christopher; Benecke, Cord; Gumz, Antje

    2017-01-01

    Psychotherapy is commonly described as a "talking cure," a treatment method that operates through linguistic action and interaction. The operative specifics of therapeutic language use, however, are insufficiently understood, mainly due to a multitude of disparate approaches that advance different notions of what "talking" means and what "cure" implies in the respective context. Accordingly, a clarification of the basic theoretical structure of "talking cure models," i.e., models that describe therapeutic processes with a focus on language use, is a desideratum of language-oriented psychotherapy research. Against this background the present paper suggests a theoretical framework of analysis which distinguishes four basic components of "talking cure models": (1) a foundational theory (which suggests how linguistic activity can affect and transform human experience), (2) an experiential problem state (which defines the problem or pathology of the patient), (3) a curative linguistic activity (which defines linguistic activities that are supposed to effectuate a curative transformation of the experiential problem state), and (4) a change mechanism (which defines the processes and effects involved in such transformations). The purpose of the framework is to establish a terminological foundation that allows for systematically reconstructing basic properties and operative mechanisms of "talking cure models." To demonstrate the applicability and utility of the framework, five distinct "talking cure models" which spell out the details of curative "talking" processes in terms of (1) catharsis, (2) symbolization, (3) narrative, (4) metaphor, and (5) neurocognitive inhibition are introduced and discussed in terms of the framework components. In summary, we hope that our framework will prove useful for the objective of clarifying the theoretical underpinnings of language-oriented psychotherapy research and help to establish a more comprehensive understanding of how curative

    Universal salt iodization is considered the best strategy for controlling iodine deficiency disorders in Nepal. This study was done to find iodized salt use among Nepalese population and the iodine content of household salts. Six districts (Siraha, Saptari, Jhapa, Udayapur, Ilam and Panchthar) were chosen randomly from 16 districts of eastern Nepal for the study. In each district, three schools (private and government) were chosen randomly for sample collection. A total of 1803 salt samples were collected from schools of those districts. For sample collection a clean air tight plastic pouch was provided to each school child and was asked to bring approximately 15 gm of their kitchen salt. The information about type of salt used; 'two child logo' iodized salt or crystal salt was obtained from each child and salt iodine content was estimated using iodometric titration. At the time of study, 85% (n=1533) of Nepalese households were found to use iodized salt whereas 15% (n=270) used crystal salt. The mean iodine content in iodized and crystal salt was 40.8±12.35 ppm and 18.43±11.49 ppm respectively. There was significant difference between iodized and crystal salts use and salt iodine content of iodized and crystal salt among different districts (p value <0.001 at confidence level of 95%). Of the total samples, only 169 samples (9.4% of samples) have iodine content<15 ppm. Most Nepalese households have access to iodized salt most salt samples have sufficient iodine content.

    Excessive dietary salt intake is related to cardiovascular morbidity and mortality. Although dietary salt restriction is essential, it is difficult to achieve because of salt palatability. However, the association between salt perception or salt eating habit and actual salt intake remains uncertain. In this study, we recruited 74 healthy young individuals. We investigated their salt-eating habits by questionnaire and salt taste threshold through a rating scale that used serial dilution of a sodium chloride solution. Predicted 24-hr urinary salt excretions using Kawasaki's and Tanaka's equations estimated dietary salt intake. Participants' mean age was 35 yr, and 59.5% were male. Salt sense threshold did not show any relationship with actual salt intake and a salt-eating habit. However, those eating "salty" foods showed higher blood pressure (P for trend=0.048) and higher body mass index (BMI; P for trend=0.043). Moreover, a salty eating habit was a significant predictor for actual salt intake (regression coefficient [β] for Kawasaki's equation 1.35, 95% confidence interval [CI] 10-2.69, P=0.048; β for Tanaka's equation 0.66, 95% CI 0.01-1.31, P=0.047). In conclusion, a self-reported salt-eating habit, not salt taste threshold predicts actual salt intake.

  8. Effect of Low Salt Diet on Insulin Resistance in Salt Sensitive versus Salt Resistant Hypertension

    2014-01-01

    Accumulating evidence shows an increase in insulin resistance on salt restriction. We compared the effect of low salt diet on insulin resistance in salt sensitive versus salt resistant hypertensive subjects. We also evaluated the relationship between salt sensitivity of blood pressure and salt sensitivity of insulin resistance in a multivariate regression model. Studies were conducted after one week of high salt (200 mmol/day Na) and one week of low salt (10 mmol/day Na) diet. Salt sensitivity was defined as the fall in systolic blood pressure >15mmHg on low salt diet. The study includes 389 subjects (44% Females, 16% Blacks, BMI 28.5±4.2 Kg/m2). As expected, blood pressure was lower on low salt (129±16/78±9 mmHg) as compared to high salt diet (145±18/86±10 mmHg). Fasting plasma glucose, insulin and HOMA were higher on low salt diet (95.4±19.4 mg/dl, 10.8±7.3 mIU/L and 2.6±1.9) as compared to high salt diet (90.6±10.8 mg/dl, 9.4±5.8 mIU/L and 2.1±1.4) (p salt sensitive (N=193) versus salt resistant (N=196) subjects on either diet. Increase in HOMA on low salt diet was 0.5±1.4 in salt sensitive and 0.4±1.5 in salt resistant subjects (p=NS). On multivariate regression analysis, change in systolic blood pressure was not associated with change in HOMA after including age, BMI, sex, change in serum and urine aldosterone and cortisol into the model. We conclude that the increase in insulin resistance on low salt diet is not affected by salt sensitivity of blood pressure. PMID:25185125

    This document is intended as a source of general information and facts about Great Salt Lake, Utah. This U.S. Geological Survey information sheet answers frequently asked questions about Great Salt Lake. Topics include: History, salinity, brine shrimp, brine flies, migratory birds, and recreation. Great Salt Lake, the shrunken remnant of prehistoric Lake Bonneville, has no outlet. Dissolved salts accumulate in the lake by evaporation. Salinity south of the causeway has ranged from 6 percent to 27 percent over a period of 22 years (2 to 7 times saltier than the ocean). The high salinity supports a mineral industry that extracts about 2 million tons of salt from the lake each year. The aquatic ecosystem consists of more than 30 species of organisms. Harvest of its best-known species, the brine shrimp, annually supplies millions of pounds of food for the aquaculture industry worldwide. The lake is used extensively by millions of migratory and nesting birds and is a place of solitude for people. All this occurs in a lake that is located at the bottom of a 35,000-square-mile drainage basin that has a human population of more than 1.5 million.

  10. Fundamental Properties of Salts

    Energy Technology Data Exchange (ETDEWEB)

    2012-11-01

    Thermal properties of molten salt systems are of interest to electrorefining operations, pertaining to both the Fuel Cycle Research & Development Program (FCR&D) and Spent Fuel Treatment Mission, currently being pursued by the Department of Energy (DOE). The phase stability of molten salts in an electrorefiner may be adversely impacted by the build-up of fission products in the electrolyte. Potential situations that need to be avoided, during electrorefining operations, include (i) fissile elements build up in the salt that might approach the criticality limits specified for the vessel, (ii) electrolyte freezing at the operating temperature of the electrorefiner due to changes in the liquidus temperature, and (iii) phase separation (non-homogenous solution). The stability (and homogeneity) of the phases can be monitored by studying the thermal characteristics of the molten salts as a function of impurity concentration. Simulated salt compositions consisting of the selected rare earth and alkaline earth chlorides, with a eutectic mixture of LiCl-KCl as the carrier electrolyte, were studied to determine the melting points (thermal characteristics) using a Differential Scanning Calorimeter (DSC). The experimental data were used to model the liquidus temperature. On the basis of the this data, it became possible to predict a spent fuel treatment processing scenario under which electrorefining could no longer be performed as a result of increasing liquidus temperatures of the electrolyte.

    Full Text Available Psychotherapy is commonly described as a “talking cure,” a treatment method that operates through linguistic action and interaction. The operative specifics of therapeutic language use, however, are insufficiently understood, mainly due to a multitude of disparate approaches that advance different notions of what “talking” means and what “cure” implies in the respective context. Accordingly, a clarification of the basic theoretical structure of “talking cure models,” i.e., models that describe therapeutic processes with a focus on language use, is a desideratum of language-oriented psychotherapy research. Against this background the present paper suggests a theoretical framework of analysis which distinguishes four basic components of “talking cure models”: (1 a foundational theory (which suggests how linguistic activity can affect and transform human experience, (2 an experiential problem state (which defines the problem or pathology of the patient, (3 a curative linguistic activity (which defines linguistic activities that are supposed to effectuate a curative transformation of the experiential problem state, and (4 a change mechanism (which defines the processes and effects involved in such transformations. The purpose of the framework is to establish a terminological foundation that allows for systematically reconstructing basic properties and operative mechanisms of “talking cure models.” To demonstrate the applicability and utility of the framework, five distinct “talking cure models” which spell out the details of curative “talking” processes in terms of (1 catharsis, (2 symbolization, (3 narrative, (4 metaphor, and (5 neurocognitive inhibition are introduced and discussed in terms of the framework components.

  10. Gas releases from salt

    1998-06-01

    The occurrence of gas in salt mines and caverns has presented some serious problems to facility operators. Salt mines have long experienced sudden, usually unexpected expulsions of gas and salt from a production face, commonly known as outbursts. Outbursts can release over one million cubic feet of methane and fractured salt, and are responsible for the lives of numerous miners and explosions. Equipment, production time, and even entire mines have been lost due to outbursts. An outburst creates a cornucopian shaped hole that can reach heights of several hundred feet. The potential occurrence of outbursts must be factored into mine design and mining methods. In caverns, the occurrence of outbursts and steady infiltration of gas into stored product can effect the quality of the product, particularly over the long-term, and in some cases renders the product unusable as is or difficult to transport. Gas has also been known to collect in the roof traps of caverns resulting in safety and operational concerns. The intent of this paper is to summarize the existing knowledge on gas releases from salt. The compiled information can provide a better understanding of the phenomena and gain insight into the causative mechanisms that, once established, can help mitigate the variety of problems associated with gas releases from salt. Outbursts, as documented in mines, are discussed first. This is followed by a discussion of the relatively slow gas infiltration into stored crude oil, as observed and modeled in the caverns of the US Strategic Petroleum Reserve. A model that predicts outburst pressure kicks in caverns is also discussed.

  11. Mechanism for salt scaling

    Science.gov (United States)

    Valenza, John J., II

    Salt scaling is superficial damage caused by freezing a saline solution on the surface of a cementitious body. The damage consists of the removal of small chips or flakes of binder. The discovery of this phenomenon in the early 1950's prompted hundreds of experimental studies, which clearly elucidated the characteristics of this damage. In particular it was shown that a pessimum salt concentration exists, where a moderate salt concentration (˜3%) results in the most damage. Despite the numerous studies, the mechanism responsible for salt scaling has not been identified. In this work it is shown that salt scaling is a result of the large thermal expansion mismatch between ice and the cementitious body, and that the mechanism responsible for damage is analogous to glue-spalling. When ice forms on a cementitious body a bi-material composite is formed. The thermal expansion coefficient of the ice is ˜5 times that of the underlying body, so when the temperature of the composite is lowered below the melting point, the ice goes into tension. Once this stress exceeds the strength of the ice, cracks initiate in the ice and propagate into the surface of the cementitious body, removing a flake of material. The glue-spall mechanism accounts for all of the characteristics of salt scaling. In particular, a theoretical analysis is presented which shows that the pessimum concentration is a consequence of the effect of brine pockets on the mechanical properties of ice, and that the damage morphology is accounted for by fracture mechanics. Finally, empirical evidence is presented that proves that the glue-small mechanism is the primary cause of salt scaling. The primary experimental tool used in this study is a novel warping experiment, where a pool of liquid is formed on top of a thin (˜3 mm) plate of cement paste. Stresses in the plate, including thermal expansion mismatch, result in warping of the plate, which is easily detected. This technique revealed the existence of

    Abiotic stresses, especially cold, salinity and drought, are the primary causes of crop loss worldwide. Plant adaptation to environmental stresses is dependent upon the activation of cascades of molecular networks involved in stress perception, signal transduction, and the expression of specific stress-related genes and metabolites. Plants have stress-specific adaptive responses as well as responses which protect the plants from more than one environmental stress. There are multiple stress perception and signaling pathways, some of which are specific, but others may cross-talk at various steps. In this review article, we first expound the general stress signal transduction pathways, and then highlight various aspects of biotic stresses signal transduction networks. On the genetic analysis, many cold induced pathways are activated to protect plants from deleterious effects of cold stress, but till date, most studied pathway is ICE-CBF-COR signaling pathway. The Salt-Overly-Sensitive (SOS) pathway, identified through isolation and study of the sos1, sos2, and sos3 mutants, is essential for maintaining favorable ion ratios in the cytoplasm and for tolerance of salt stress. Both ABA-dependent and -independent signaling pathways appear to be involved in osmotic stress tolerance. ROS play a dual role in the response of plants to abiotic stresses functioning as toxic by-products of stress metabolism, as well as important signal transduction molecules and the ROS signaling networks can control growth, development, and stress response. Finally, we talk about the common regulatory system and cross-talk among biotic stresses, with particular emphasis on the MAPK cascades and the cross-talk between ABA signaling and biotic signaling.

  13. Oxygen sparging of residue salts

    1993-03-01

    Oxygen sparge is a process for treating salt residues at Los Alamos National Laboratory by sparging oxygen through molten salts. Oxygen reacts with the plutonium trichloride in these salts to form plutonium dioxide. There is further reaction of the plutonium dioxide with plutonium metal and the molten salt to form plutonium oxychloride. Both of the oxide plutonium species are insoluble in the salt and collect atthe bottom of the crucible. This results in a decrease of a factor of 2--3 in the amount of salt that must be treated, and the amount of waste generated by aqueous treatment methods.

  4. Salt ingestion caves.

    2006-01-01

    Full Text Available Large vertebrate herbivores, when they find a salt-bearing layer of rock, say in a cliff face, can produce sizable voids where, overgenerations, they have removed and consumed salty rock. The cavities formed by this natural animal process constitute a uniqueclass of caves that can be called salt ingestion caves. Several examples of such caves are described in various publications. Anexample in Mississippi U.S.A., Rock House Cave, was visited by the authors in 2000. It seems to have been formed by deer orbison. Perhaps the most spectacular example is Kitum Cave in Kenya. This cave has been excavated to a length over 100 metersby elephants. An ancient example is La Cueva del Milodon in Chile, which is reported to have been excavated by the now extinctmilodon, a giant ground sloth. Still other possible examples can be cited. This class of caves deserves a careful definition. First, thecavity in rock should meet the size and other conventions of the locally accepted definition of a cave. Of course this requirement differsin detail from country to country, particularly in the matter of size. The intent is to respect the local conventions. The characteristicthat human entry is possible is judged to be a crucial property of any recognized cave definition. Second, the cavity should besignificantly the result of vertebrate animal consumption of salt-bearing rock. The defining process is that rock removed to form thecave is carried away in the digestive track of an animal. While sodium salts are expected to be the norm, other salts for which thereis animal hunger are acceptable. Also some other speleogenesis process, such as solution, should not be excluded as long as it issecondary in formation of a cave in question.

    Why didn't we all just stay home today? Partly, we like to hear people talk. It’s more fun than reading. Podcasts (downloadable audio files created on a computer) allow us to easily become radio producers and exploit the power of audio. The listener may relate on an intimate level to discussions, conversations, and stories that are communicated through this medium. Therefore, science topics with strong societal or human connections are ideal candidates for podcasting. Nanotechnology has the potential to change the world through advances in medicine, computing, environmental sensing, renewable energy, fuel, and more. The public remains largely uninformed, however, about nanotechnology, and its potential benefits and risks. I will show you how we have used podcasts to broadcast conversations with researchers about nanotechnology. I will also talk about other public programs at the Exploratorium which engage the public in discussions about this emerging science. (See http://www.nisenet.org/)

    Importance Physicians may be important sources of sexuality information and preventive services, and one-on-one confidential time during health maintenance visits is recommended to allow discussions of sexual development, behavior, and risk reduction. However, little is known about the occurrence and characteristics of physician-adolescent discussions about sexuality. Objective To examine predictors of time spent discussing sexuality, level of adolescent participation, and physician and patient characteristics associated with sexuality discussions during health maintenance visits by early and middle adolescents. Design, Setting, and Participants Observational study of audio-recorded conversations between 253 adolescents (mean age, 14.3 years; 53% female; 40% white; 47% African American) and 49 physicians (82% pediatricians; 84% white; 65% female; mean age, 40.9 years; mean [SD] duration in practice, 11.8 [8.7] years) coded for sexuality content at 11 clinics (3 academic and 8 community-based practices) located throughout the Raleigh/Durham, North Carolina, area. Main Outcomes and Measures Total time per visit during which sexuality issues were discussed. Results One hundred sixty-five (65%) of all visits had some sexual content within it. The average time of sexuality talk was 36 seconds (35% 0 seconds; 30% 1-35 seconds; and 35% ≥36 seconds). Ordinal logistic regression (outcome of duration: 0, 1-35, or ≥36 seconds), adjusted for clustering of patients within physicians, found that female patients (odds ratio [OR] = 2.58; 95% CI, 1.53-4.36), older patients (OR = 1.37; 95% CI, 1.13-1.65), conversations with explicit confidentiality discussions (OR = 4.33; 95% CI, 2.58-7.28), African American adolescents (OR = 1.58; 95% CI, 1.01-2.48), and longer overall visit (OR = 1.07; 95% CI, 1.03-1.11) were associated with more sexuality talk, and Asian physicians were associated with less sexuality talk (OR = 0.13; 95% CI, 0.08-0.20).

    The main purpose of this investigation was to study the mechanisms of mixed salt crystallisation fouling on heat transfer surfaces during convective heat transfer and sub-cooled flow boiling conditions. To-date no investigations on the effects of operating parameters on the deposition of mixtures of calcium sulphate and calcium carbonate, which are the most common constituents of scales formed on heat transfer surfaces, have been reported. As part of this research project, a substantial number of experiments were performed to determine the mechanisms controlling deposition. Fluid velocity, heat flux, surface and bulk temperatures, concentration of the solution, ionic strength, pressure and heat transfer surface material were varied systematically. After clarification of the effect of these parameters on the deposition process, the results of these experiments were used to develop a mechanistic model for prediction of fouling resistances, caused by crystallisation of mixed salts, under convective heat transfer...

  12. Thermochemical Properties of Nicotine Salts

    Directory of Open Access Journals (Sweden)

    Riggs DM

    2014-12-01

    Full Text Available The thermal gravimetric analysis (TGA and differential scanning calorimetry (DSC results presented in this report clearly show that the thermal stability and the endothermic peak nicotine release temperatures are different for different nicotine salts and these temperatures appear to be linked to the general microstructural details of the salt itself. In addition, the peak nicotine release temperatures are highly dependent upon the sample size used. The heat of vaporization for neat (non-protonated nicotine is also sample-size dependent. The TGA data showed that the least stable of the salts tested at elevated temperatures was the liquid salt nicotine triacetate followed by the crystalline materials (e.g., nicotine gallate and finally, the amorphous salts (e.g., nicotine alginate. The DSC results revealed that the liquid and crystalline salts exhibit nicotine release endotherms that are strongly related to the sample weight being tested. The amorphous salts show nicotine endotherm peak temperatures that are nearly independent of the sample weight. The range of peak nicotine release temperatures varied depending upon the specific salts and the sample size from 83 oC to well over 200 oC. Based on these results, the evolution of nicotine from the nicotine salt should be expected to vary based on the composition of the salt, the details of its microstructure, and the amount of nicotine salt tested.

  13. Molecular genetic perspectives on cross-talk and specificity in abiotic stress signalling in plants.

    Science.gov (United States)

    Chinnusamy, Viswanathan; Schumaker, Karen; Zhu, Jian-Kang

    2004-01-01

    The perception of abiotic stresses and signal transduction to switch on adaptive responses are critical steps in determining the survival and reproduction of plants exposed to adverse environments. Plants have stress-specific adaptive responses as well as responses which protect the plants from more than one environmental stress. There are multiple stress perception and signalling pathways, some of which are specific, but others may cross-talk at various steps. Recently, progress has been made in identifying components of signalling pathways involved in salt, drought and cold stresses. Genetic analysis has defined the Salt-Overly-Sensitive (SOS) pathway, in which a salt stress-induced calcium signal is probably sensed by the calcium-binding protein SOS3 which then activates the protein kinase SOS2. The SOS3-SOS2 kinase complex regulates the expression and activity of ion transporters such as SOS1 to re-establish cellular ionic homeostasis under salinity. The ICE1 (Inducer of CBF Expression 1)-CBF (C-Repeat Binding Protein) pathway is critical for the regulation of the cold-responsive transcriptome and acquired freezing tolerance, although at present the signalling events that activate the ICE1 transcription factor during cold stress are not known. Both ABA-dependent and -independent signalling pathways appear to be involved in osmotic stress tolerance. Components of mitogen-activated protein kinase (MAPK) cascades may act as converging points of multiple abiotic as well as biotic stress signalling pathways. Forward and reverse genetic analysis in combination with expression profiling will continue to uncover many signalling components, and biochemical characterization of the signalling complexes will be required to determine specificity and cross-talk in abiotic stress signalling pathways.

    2012-01-01

    Full Text Available Abstract: The use of constructive teacher talk (TT is very important and effective in scaffolding young learners to improve their skill in target language. Nevertheless, there is an argument that too much teacher talk can even decrease students’ motivation. The present study tries to reveal the suitable amount and the students’ perception of teacher talk. Apart from that, there is an attempt to find out the features of teacher talk, the frequency of either display and referential questions or teachers’ assessments and ways in giving feedback. This descriptive study is conducted to find out how teachers make use of their teacher talk naturally in classroom settings. To gain deeper insight and understanding, both qualitative and quantitative research design were employed. The qualitative data were obtained through direct observation and teachers – students’ interview. Moreover, the teachers – students’ questionnaire, video recording and field notes also added significant value towards the findings of this study. Quantitative data, on the other hand, were gained from the calculation of students’ questionnaire scores which are represented in percentage. Both qualitative and quantitative data were coded, categorized, interpreted, descriptively described and finally displayed in the form of tables. The research findings show that despite the teacher talk’s capability to be good model for young learners,  most students found the class more motivating, interesting, and challenging when the teachers minimized their teacher talk  and made use not only more constructive teacher talk but also  interesting activities. In conclusion, since teacher talk serves not only as a medium to achieve young learners’s learning objectives but also as a tool to build better dynamic interaction between teacher and students in classroom settings, it is advisable for all EFL teachers to improve their effective constructive talk towards their students

Droplets are an ideal confining geometry because the length scales can be easily controlled and it is possible to arrange the system such that each droplet acts as an independent experiment. The talk will focus on some recent examples where we have used the droplet geometry to learn about material properties. It will become apparent in the presentation that the deviations from the ``expected'' behaviour in confined systems are far from subtle!

    Many of us have to create software as part of our work, if you do probably you asked yourself some of the following: How other people at CERN develop? What technologies have they used? What worked and what didn't for them? Am I reinventing the wheel? What CERN services can make my life easier? What other services I miss that would be useful to have? How can I integrate my system with XXYY at CERN? Unfortunately there is little communication between us and we need to fix that, let's find initiatives to improve and share experiences between software engineers... let's talk!

    OpenAIRE

    Tournier, Carole; Knoop, Janine E.; Kooyman, Gonnie; Smit, Gerrit

    2009-01-01

    The impact of salt delivery in mouth on salt perception was investigated. It was hypothesized that fast concentration changes in the delivery to the receptor can reduce sensory adaptation, leading to an increased taste perception. Saltiness ratings were scored by a panel over time during various stimulation conditions involving relative changes in NaCl concentration of 20% and 38%. Changes in salt delivery profile had similar effect on saltiness perception when delivered either by a sipwise m...

  1. Rheology of rock salt for salt tectonics modeling

    2016-10-01

    Full Text Available Abstract Numerical modeling of salt tectonics is a rapidly evolving field; however, the constitutive equations to model long-term rock salt rheology in nature still remain controversial. Firstly, we built a database about the strain rate versus the differential stress through collecting the data from salt creep experiments at a range of temperatures (20–200 °C in laboratories. The aim is to collect data about salt deformation in nature, and the flow properties can be extracted from the data in laboratory experiments. Moreover, as an important preparation for salt tectonics modeling, a numerical model based on creep experiments of rock salt was developed in order to verify the specific model using the Abaqus package. Finally, under the condition of low differential stresses, the deformation mechanism would be extrapolated and discussed according to microstructure research. Since the studies of salt deformation in nature are the reliable extrapolation of laboratory data, we simplified the rock salt rheology to dislocation creep corresponding to power law creep (n = 5 with the appropriate material parameters in the salt tectonic modeling.

    Metal complex salts may be used in lithium ion batteries. Such metal complex salts not only perform as an electrolyte salt in a lithium ion batteries with high solubility and conductivity, but also can act as redox shuttles that provide overcharge protection of individual cells in a battery pack and/or as electrolyte additives to provide other mechanisms to provide overcharge protection to lithium ion batteries. The metal complex salts have at least one aromatic ring. The aromatic moiety may be reversibly oxidized/reduced at a potential slightly higher than the working potential of the positive electrode in the lithium ion battery. The metal complex salts may also be known as overcharge protection salts.

    2018-02-01

    In accord with articles 19 and 27 of the Universal Declaration of Human Rights, people with speech and language disorders have the right to receive maximal benefit from academic research on speech and language acquisition and disorders. To evaluate the diverse nature of speech and language disorders, this research must have access to large datasets, as well as to refined tools for the systematic analysis of these datasets. The TalkBank system addresses this need by providing researchers with thousands of hours of open-access database archives of digital audio, video and transcript files documenting typical and disordered language use in dozens of languages and cultures. In this paper, we review the TalkBank system, with an emphasis on the AphasiaBank, PhonBank and FluencyBank databases. We describe how specialised assessment tools can be used to study issues in speech and language acquisition and disorders recorded within these databases. We then provide illustrations of how assessments support the needs of researchers, clinicians, developers, and educators, whose combined work contributes solutions for people with speech, language and language learning disorders worldwide.

  13. Salt fluoridation and oral health

    Full Text Available The aim of this paper is to make known the potential of fluoridated salt in community oral health programs, particularly in South Eastern Europe. Since 1922, the addition of iodine to salt has been successful in Switzerland. Goiter is virtually extinct. By 1945, the cariesprotective effect of fluorides was well established. Based on the success of water fluoridation, a gynecologist started adding of fluoride to salt. The sale of fluoridated salt began in 1956 in the Swiss Canton of Zurich, and several other cantons followed suit. Studies initiated in the early seventies showed that fluoride, when added to salt, inhibits dental caries. The addition of fluoride to salt for human consumption was officially authorized in 1980-82. In Switzerland 85% of domestic salt consumed is fluoridated and 67% in Germany. Salt fluoridation schemes are reaching more than one hundred million in Mexico, Colombia, Peru and Cuba. The cost of salt fluoridation is very low, within 0.02 and 0.05 € per year and capita. Children and adults of the low socio-economic strata tend to have substantially more untreated caries than higher strata. Salt fluoridation is by far the cheapest method for improving oral health. Conclusions. Salt fluoridation has cariostatic potential like water fluoridation (caries reductions up to 50%. In Europe, meaningful percentages of users have been attained only in Germany (67% and Switzerland (85%. In Latin America, there are more than 100 million users, and several countries have arrived at coverage of 90 to 99%. Salt fluoridation is by far the cheapest method of caries prevention, and billions of people throughout the world could benefit from this method.

    Families discuss food and eating in many ways that may shape child eating habits. Researchers studying how families talk about food have examined this process during meals. Little work has examined parent-child food-related interactions outside of mealtime. We assessed family food talk at home outside of mealtime and tested whether food talk was associated with obesogenic child eating behaviors, maternal feeding practices, or child weight. Preschool and school-aged mother-child dyads (n = 61) participated in naturalistic voice recording using a LENA (Language ENvironment Analysis) recorder. A coding scheme was developed to reliably characterize different types of food talk from LENA transcripts. Mothers completed the Children's Eating Behavior Questionnaire (CEBQ) and Child Feeding Questionnaire (CFQ) to assess child eating behaviors and maternal feeding practices. Child weight and height were measured and body mass index z-score (BMIz) calculated. Bivariate associations among food talk types, as a proportion of total speech, were examined and multivariate regression models used to test associations between food talk and child eating behaviors, maternal feeding practices, and child BMIz.

  16. Dietary Salt Intake and Hypertension

    Science.gov (United States)

    2014-01-01

    Over the past century, salt has been the subject of intense scientific research related to blood pressure elevation and cardiovascular mortalities. Moderate reduction of dietary salt intake is generally an effective measure to reduce blood pressure. However, recently some in the academic society and lay media dispute the benefits of salt restriction, pointing to inconsistent outcomes noted in some observational studies. A reduction in dietary salt from the current intake of 9-12 g/day to the recommended level of less than 5-6 g/day will have major beneficial effects on cardiovascular health along with major healthcare cost savings around the world. The World Health Organization (WHO) strongly recommended to reduce dietary salt intake as one of the top priority actions to tackle the global non-communicable disease crisis and has urged member nations to take action to reduce population wide dietary salt intake to decrease the number of deaths from hypertension, cardiovascular disease and stroke. However, some scientists still advocate the possibility of increased risk of CVD morbidity and mortality at extremes of low salt intake. Future research may inform the optimal sodium reduction strategies and intake targets for general populations. Until then, we have to continue to build consensus around the greatest benefits of salt reduction for CVD prevention, and dietary salt intake reduction strategies must remain at the top of the public health agenda.

    Chrysanthemum lavandulifolium (Fisch. ex Trautv.) Makino is a halophyte species that belongs to the Asteraceae family, and the genus Chrysanthemum. It is one of the ancestors of C.×morifolium Ramatella. Understanding the tolerance mechanism associated with salt stress in C. lavandulifolium could provide important information for explaining the salt tolerance of higher plants and could also help enhancing breeding programs of cultivated Chrysanthemum. In this study, cDNA amplified fragment length polymorphism (cDNA-AFLP) was used to detect differential gene expression in leaves of C. lavandulifolium in response to NaCl treatment. The determination of membrane permeablility, peroxidase activity (POD), malon-dialdehyde (MDA), as well as proline and leaf chlorophyll contents under different NaCl concentrations showed that a 200 mM NaCl treatment was an optimal condition for the cDNA-AFLP experiment. Using this concentration during different times (0, 3 h, 12 h, 24 h and 48 h), we obtained 1930 cDNA fragments using 64 primers. After sequencing 234 randomly chosen cDNA clones and BLASTx analyzing, we got 129 expressed sequence tags (ESTs) which had no significant homology with other sequences, 85 ESTs were homologous to genes with known functions, whereas the rest of ESTs showed homology to unclassified or putative proteins. 25 ESTs that were similar to known functional genes involved in several abiotic and biotic stresses were confirmed by semi-quantitative RT-PCR and qRT-PCR. The expression patterns of these salt-responsive genes not only responded to salt stress but also to plant hormones, such as abscisic acid (ABA), and to other abiotic stresses such as drought and cold. These results indicate an extensive cross-talk among several stresses. Our results provide interesting information for further understanding the molecular mechanisms of salt tolerance in C. lavandulifolium. Copyright © 2011 Elsevier GmbH. All rights reserved.

    1977-02-01

    The bile salts secretion was studied in ten normal subjects and sixteen patients with alcoholic cirrhosis, in a basal period and during 60 minutes after Secretin injection. Total bile salts were measured by a modification of the enzymatic method of Iwata and Yamasaki and the individual bile salts were separated by silica gel thin-layer chromatography. During the 60 minutes after Secretin the mean concentration was 2.88 +/- 2.58 muM/ml in normals and 1.96 +/- 1.25 muM/ml in cirrhotics. The difference is not significant. During the first 20 minutes however the concentration was higher than 3 muM/ml in 8 out of 10 normals and lower than 2 muM/ml in 10 out 16 cirrhotics. The ratios of tri-to dihydroxy bile salts was similar in both groups. The ratios between bile salts conjugated with glycine and with taurine was higher in normals, and the ratio between free to conjugated bile salts was higher in cirrhotics. The lower concentration of total bile salts immediatly after Secretin, the higher proportion of taurin conjugates and of free bile salts could be important factors in the difficulties of fact digestion and absorption frequently found in patients with alcoholic cirrhosis.

    Soil salinity is a major constraint to agriculture. To improve salinity tolerance of crops, various traits can be incorporated, including ion exclusion, osmotic tolerance and tissue tolerance. We review the roles of a range of genes involved in salt tolerance traits. Different tissues and cells are adapted for specific and often diverse function, so it is important to express the genes in specific cell-types and to pyramid a range of traits. Modern biotechnology (marker- assisted selection or genetic engineering) needs to be increasingly used to introduce the correct combination of genes into elite crop cultivars. Importantly, the effects of introduced genes need to be evaluated in the field to determine their effect on salinity tolerance and yield improvement.

    These plots, or spectra, show that a rock dubbed 'McKittrick' near the Mars Exploration Rover Opportunity's landing site at Meridiani Planum, Mars, has higher concentrations of sulfur and bromine than a nearby patch of soil nicknamed 'Tarmac.' These data were taken by Opportunity's alpha particle X-ray spectrometer, which uses curium-244 to assess the elemental composition of rocks and soil. Only portions of the targets' full spectra are shown to highlight the significant differences in elemental concentrations between 'McKittrick' and 'Tarmac.' Intensities are plotted on a logarithmic scale.A nearby rock named Guadalupe similarly has extremely high concentrations of sulfur, but very little bromine. This 'element fractionation' typically occurs when a watery brine slowly evaporates and various salt compounds are precipitated in sequence.

    Salt is condition for the survival of the human race, and holds a special place in the exploitation of mineral resources. It is the only mineral raw material used in direct feeding, and therefore has its own specialty. Salt is a crystalline mineral that is found in seawater, as well as in underground areas where it is formed by deposition of salt sediments. Occurrences of salt water near Tuzla and Gornja Tuzla have been known since the time of the Romans as "ad salinas". The name itself connects Bosnia with its richness in salt, because the word barefoot, which is preserved in a north-Albanian dialect, means a place where boiling salted water are obtained. At the time of the Bosnian kings, these regions are named Soli, which is in connection with occurences of saline sources. Geological studies of rock salt in the area of Tuzla basin are practically began after the annexation of Bosnia and Herzegovina by the Austro-Hungarian Empire, in the period from 1878 to 1918. Geological field work was conducted K. Paul, H. Hefer, E. Tietze and F. Katzer. Monomineral deposit of rock salt Tetima is made of halite and anhydrite mixed with marl belt, while the bay of salt in Tuzla is polymineral and contains a considerable amount of thenardite (Na2SO4) and rare minerals: nortupit, nahkolit, bradleit, probertit, glauberite and others. Both salt deposits were created as a product of chemical sedimentation in the lower Miocene Badenian sediments. The main objective of this paper is to show the genesis of the deposits and the spatial and genetic connection. In addition, genesis of geological research in the areas of Tuzla basin will be presented.

  9. Molten Salt Promoting Effect in Double Salt CO2 Absorbents

    Energy Technology Data Exchange (ETDEWEB)

    Zhang, Keling; Li, Xiaohong S.; Chen, Haobo; Singh, Prabhakar; King, David L.

    2016-01-01

    The purpose of this paper is to elaborate on the concept of molten salts as catalysts for CO2 absorption by MgO, and extend these observations to the MgO-containing double salt oxides. We will show that the phenomena involved with CO2 absorption by MgO and MgO-based double salts are similar and general, but with some important differences. This paper focuses on the following key concepts: i) identification of conditions that favor or disfavor participation of isolated MgO during double salt absorption, and investigation of methods to increase the absorption capacity of double salt systems by including MgO participation; ii) examination of the relationship between CO2 uptake and melting point of the promoter salt, leading to the recognition of the role of pre-melting (surface melting) in these systems; and iii) extension of the reaction pathway model developed for the MgO-NaNO3 system to the double salt systems. This information advances our understanding of MgO-based CO2 absorption systems for application with pre-combustion gas streams.

    2015-03-01

    Full Text Available Iodized salt has been an important source of dietary iodine, a trace element important for regulating human growth, development, and metabolic functions. This analysis identified iodized table salt sales as a percentage of retail salt sales using Nielsen ScanTrack. We identified 1117 salt products, including 701 salt blends and 416 other salt products, 57 of which were iodized. When weighted by sales volume in ounces or per item, 53% contained iodized salt. These findings may provide a baseline for future monitoring of sales of iodized salt.

  11. Does stress induce salt intake?

    Torres, Susan J; Turner, Anne I; Nowson, Caryl A

    2010-06-01

    Psychological stress is a common feature of modern day societies, and contributes to the global burden of disease. It was proposed by Henry over 20 years ago that the salt intake of a society reflects the level of stress, and that stress, through its effect on increasing salt intake, is an important factor in the development of hypertension. This review evaluates the evidence from animal and human studies to determine if stress does induce a salt appetite and increase salt consumption in human subjects. Findings from animal studies suggest that stress may drive salt intake, with evidence for a potential mechanism via the sympatho-adrenal medullary system and/or the hypothalamo-pituitary-adrenal axis. In contrast, in the few laboratory studies conducted in human subjects, none has found that acute stress affects salt intake. However, one study demonstrated that life stress (chronic stress) was associated with increased consumption of snack foods, which included, but not specifically, highly salty snacks. Studies investigating the influence of chronic stress on eating behaviours are required, including consumption of salty foods. From the available evidence, we can conclude that in free-living, Na-replete individuals, consuming Na in excess of physiological requirements, stress is unlikely to be a major contributor to salt intake.

  12. Dietary Salt Exacerbates Experimental Colitis.

    2017-08-01

    The Western diet is characterized by high protein, sugar, fat, and low fiber intake, and is widely believed to contribute to the incidence and pathogenesis of inflammatory bowel disease (IBD). However, high sodium chloride salt content, a defining feature of processed foods, has not been considered as a possible environmental factor that might drive IBD. We set out to bridge this gap. We examined murine models of colitis on either a high salt diet (HSD) or a low salt diet. We demonstrate that an HSD exacerbates inflammatory pathology in the IL-10-deficient murine model of colitis relative to mice fed a low salt diet. This was correlated with enhanced expression of numerous proinflammatory cytokines. Surprisingly, sodium accumulated in the colons of mice on an HSD, suggesting a direct effect of salt within the colon. Similar to the IL-10-deficient model, an HSD also enhanced cytokine expression during infection by Salmonella typhimurium This occurred in the first 3 d of infection, suggesting that an HSD potentiates an innate immune response. Indeed, in cultured dendritic cells we found that high salt media potentiates cytokine expression downstream of TLR4 activation via p38 MAPK and SGK1. A third common colitis model, administration of dextran sodium sulfate, was hopelessly confounded by the high sodium content of the dextran sodium sulfate. Our results raise the possibility that high dietary salt is an environmental factor that drives increased inflammation in IBD. Copyright © 2017 by The American Association of Immunologists, Inc.

    Although "fat talk" is associated with increased eating disorder risk, the predictors of fat talk engagement and viable alternatives to these pervasive conversations remain unclear. The current experiment examined responses to fat talk versus feminist-oriented challenging fat talk scenarios. Undergraduate women (N=283) completed baseline questionnaires assessing body dissatisfaction, fat talk engagement, and positive impression management. One week later, they were randomized to view one of the two scenarios, followed by assessment of mood, fat talk engagement, social acceptability, and social likeability. Results indicated that the challenging fat talk vignette (versus the fat talk vignette) yielded less negative affect and fat talk and was perceived as more socially attractive with a more likeable target character. Baseline body dissatisfaction, baseline fat talk tendencies, and momentary negative affect predicted post-exposure fat talk engagement. Current findings highlight possibilities for implementing feminist language and psychoeducation in fat talk prevention efforts. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2009-05-01

    The impact of salt delivery in mouth on salt perception was investigated. It was hypothesized that fast concentration changes in the delivery to the receptor can reduce sensory adaptation, leading to an increased taste perception. Saltiness ratings were scored by a panel over time during various stimulation conditions involving relative changes in NaCl concentration of 20% and 38%. Changes in salt delivery profile had similar effect on saltiness perception when delivered either by a sipwise method or by a gustometer. The impact of concentration variations and frequency of concentration changes was further investigated with the gustometer method. Five second boosts and 2 s pulses were delivered during 3 sequential 10-s intervals, whereas the delivered total salt content was the same for all conditions. Two second pulses were found to increase saltiness perception, but only when the pulses were delivered during the first seconds of stimulation. Results suggest that the frequency, timing, and concentration differences of salt stimuli can affect saltiness. Specifically, a short and intense stimulus can increase salt perception, possibly through a reduction of adaptation.

  15. Salt intake, plasma sodium, and worldwide salt reduction.

    He, Feng J; Macgregor, Graham A

    2012-06-01

    There is overwhelming evidence that a reduction in salt intake from the current level of approximately 9-12 g/d in most countries of the world to the recommended level of 5-6 g/d lowers blood pressure (BP) in both hypertensive and normotensive individuals. A further reduction to 3-4 g/d has a greater effect. Prospective studies and outcome trials have demonstrated that a lower salt intake is related to a reduced risk of cardiovascular disease. Cost-effectiveness analyses have documented that salt reduction is more or at the very least just as cost-effective as tobacco control in reducing cardiovascular disease, the leading cause of death and disability worldwide. The mechanisms whereby salt raises blood pressure and increases cardiovascular risk are not fully understood. The existing concepts focus on the tendency for an increase in extracellular fluid volume. Increasing evidence suggests that small increases in plasma sodium may have a direct effect on BP and the cardiovascular system, independent of extracellular volume. All countries should adopt a coherent and workable strategy to reduce salt intake in the whole population. Even a modest reduction in population salt intake will have major beneficial effects on health, along with major cost savings.

    In the last issue of Healthcare Executive, we introduced the first in a two-part series on quality in healthcare. The series, which is predicated on a five-hour roundtable discussion among eight healthcare leaders, was moderated by Thomas C. Dolan, Ph.D., FACHE, CAE, ACHE's president and chief executive officer, and jointly sponsored by ACHE and the Bayer Quality Network, an educational forum for sharing innovative and effective continuous quality improvement methods with healthcare executives. In Part I, participants spoke about current issues as they relate to quality. They discussed the reliability of existing quality data and expressed a need for more practical indicators and measurement systems. The consumer mindset was discussed, as leaders debated the value of customer satisfaction surveys and ways to create more realistic consumer expectations. In terms of employers and third parties, participants suggested tailoring quality information and presenting it in a simplified fashion. Finally, leaders emphasized the need for better performance information, as well as the use of outcomes data for both educational and quality improvement purposes. In Part II, the dialogue remains compelling. Participants cover new ground as they talk about the role of accreditors in regulating quality, of governance teams and senior management in creating an organizational culture to support quality, and of physicians in attracting both business partners and patients based on quality. Following is the second in our two-part series.

  18. Salting-in and salting-out of water-soluble polymers in aqueous salt solutions.

    Sadeghi, Rahmat; Jahani, Farahnaz

    2012-05-03

    To obtain further experimental evidence for the mechanisms of the salting effect produced by the addition of salting-out or sating-in inducing electrolytes to aqueous solutions of water-soluble polymers, systematic studies on the vapor-liquid equilibria and liquid-liquid equilibria of aqueous solutions of several polymers are performed in the presence of a large series of electrolytes. Polymers are polyethylene glycol 400 (PEG400), polyethylene glycol dimethyl ether 250 (PEGDME250), polyethylene glycol dimethyl ether 2000 (PEGDME2000), and polypropylene glycol 400 (PPG400), and the investigated electrolytes are KCl, NH(4)Cl, MgCl(2), (CH(3))(4)NCl, NaCl, NaNO(3), Na(2)CO(3), Na(2)SO(4), and Na(3)Cit (tri-sodium citrate). Aqueous solutions of PPG400 form aqueous two-phase systems with all the investigated salts; however, other investigated polymers form aqueous two-phase systems only with Na(2)CO(3), Na(2)SO(4), and Na(3)Cit. A relation was found between the salting-out or sating-in effects of electrolyte on the polymer aqueous solutions and the slopes of the constant water activity lines of ternary polymer-salt aqueous solutions, so that, in the case of the salting-out effect, the constant water activity lines had a concave slope, but in the case of the salting-in effects, the constant water activity lines had a convex slope. The effect of temperature, anion of electrolyte, cation of electrolyte, and type and molar mass of polymers were studied and the results interpreted in terms of the solute-water and solute-solute interactions. The salting-out effect results from the formation of ion (specially anion)-water hydration complexes, which, in turn, decreases hydration, and hence, the solubility of the polymer and the salting-in effect results from a direct binding of the cations to the ether oxygens of the polymers.

    2012-01-01

    Full Text Available The use of constructive teacher talk (TT is very important and effective in scaffolding young learners to improve their skill in target language. Nevertheless, there is an argument that too much teacher talk can even decrease students’ motivation. The present study tries to reveal the suitable amount and the students’ perception of teacher talk. Apart from that, there is an attempt to find out the features of teacher talk, the frequency of either display and referential questions or teachers’ assessments and ways in giving feedback. This descriptive study is conducted to find out how teachers make use of their teacher talk naturally in classroom settings. To gain deeper insight and understanding, both qualitative and quantitative research design were employed. The qualitative data were obtained through direct observation and teachers – students’ interview. Moreover, the teachers – students’ questionnaire, video recording and field notes also added significant value towards the findings of this study. Quantitative data, on the other hand, were gained from the calculation of students’ questionnaire scores which are represented in percentage. Both qualitative and quantitative data were coded, categorized, interpreted, descriptively described and finally displayed in the form of tables. The research findings show that despite the teacher talk’s capability to be good model for young learners, most students found the class more motivating, interesting, and challenging when the teachers minimized their teacher talk and made use not only more constructive teacher talk but also interesting activities. In conclusion, since teacher talk serves not only as a medium to achieve young learners’s learning objectives but also as a tool to build better dynamic interaction between teacher and students in classroom settings, it is advisable for all EFL teachers to improve their effective constructive talk towards their students.

    Cross-talk is broadly defined as endogenous homeostatic signaling between vital organs such as the heart, kidneys and brain. Kidney-brain cross-talk remains an area with excitingly few publications despite its purported clinical relevance in the management of currently undertreated conditions such as resistant hypertension. Therefore, this review aims to establish an organ-specific definition for kidney-brain cross-talk and review the available and forthcoming literature on this topic.

    Solar salt ponds are shallow ponds of brines that range in salinity from that of normal seawater (3.4 percent) through NaCl saturation. Some salterns evaporate brines to the potash stage of concentration (bitterns). All the brines (except the bitterns, which are devoid of life) harbor high concentrations of microorganisms. The high concentrations of microorganisms and their adaptation to life in the salt pond are discussed.

    1991-12-01

    The secondary aluminum industry generates more than 110 {times} 10{sup 3} tons of salt-cake waste every year. This waste stream contains about 3--5% aluminum, 15--30% aluminum oxide, 30--40% sodium chloride, and 20--30% potassium chloride. As much as 50% of the content of this waste is combined salt (sodium and potassium chlorides). Salt-cake waste is currently disposed of in conventional landfills. In addition, over 50 {times} 10{sup 3} tons of black dross that is not economical to reprocess a rotary furnace for aluminum recovery ends up in landfills. The composition of the dross is similar to that of salt cake, except that it contains higher concentrations of aluminum (up to 20%) and correspondingly lower amounts of salts. Because of the high solubility of the salts in water, these residues, when put in landfills, represent a potential source of pollution to surface-water and groundwater supplies. The increasing number of environmental regulations on the generation and disposal of industrial wastes are likely to restrict the disposal of these salt-containing wastes in conventional landfills. Processes exist that employ the dissolution and recovery of the salts from the waste stream. These wet-processing methods are economical only when the aluminum concentration in that waste exceeds about 10%. Argonne National Laboratory (ANL) conducted a study in which existing technologies were reviewed and new concepts that are potentially more cost-effective than existing processes were developed and evaluated. These include freeze crystallization, solvent/antisolvent extraction, common-ion effect, high-pressure/high-temperature process, and capillary-effect systems. This paper presents some of the technical and economic results of the aforementioned ANL study.

    2016-01-01

    This study investigated the impact of salt reduction on liking, salt taste perception, and use of table salt when consuming chicken stew in light of South Africa's new salt recommendations. In total, 432 South-African consumers (aged 35.2 ± 12.3 years) consumed a full portion of a chicken stew meal once at a central location. Four stock cube powders varying in salt content were used to prepare chicken stews: 1) no reduction - 2013 Na level; regular salt level as currently available on the South African market (24473 mg Na/100 g), 2) salt reduction smaller than 2016 level, i.e. 10%-reduced (22025 mg Na/100 g), 3) 2016 salt level, as per regulatory prescriptions (18000 mg Na/100 g), 4) 2019 salt level, as per regulatory prescriptions (13000 mg Na/100 g). Consumers were randomly allocated to consume one of the four meals. Liking, salt taste perception, and use of table salt and pepper were measured. Chicken stews prepared with reduced-salt stock powders were equally well-liked as chicken stews with the current salt level. Moreover, a gradual reduction of the salt in the chicken stews resulted in a reduced salt intake, up to an average of 19% for the total group compared to the benchmark 2013 Na level stew. However, 19% of consumers compensated by adding salt back to full compensation in some cases. More salt was added with increased reductions of salt in the meals, even to the point of full compensation. Further investigation into the impacts of nutrition communication and education about salt reduction on salt taste perception and use is needed. This research provides new consumer insights on salt use and emphasises the need for consumer-focused behaviour change approaches, in addition to reformulation of products.

  7. Identifying and Supporting Productive Collaborative Teacher Talk

    Science.gov (United States)

    Flarend, Alice M.

    As improvements and changes in science education are promulgated, science teachers must be educated about these changes. Professional development programs are central to promoting teacher learning. Although the field seems to have agreed upon large-scalepedagogical features of high quality professional development with an emphasis on building a collaborative community of learners, effective implementation of these features is still problematic. The connections between these collaborative features and actual teacher work during the professional development remain unclear. This qualitative discourse study investigated how teachers engaged in small group discussions use discourse to collaborate during a weeklong professional development program that employed these useful pedagogical features. Small group discussions among the forty-two participants, diverse in their demographics and teaching experiences, were video and audio recorded. A collaborative discourse framework is developed and applied to the discussions, successfully categorizing episodes of discourse according to their productive potential for learning. The structure of the PD activities is then investigated to determine characteristics encouraging to these productive learning conversations. The analysis in this study indicated requiring groups to come to a consensus helps groups dig deeper into the content, promoting a more productive negotiation of concepts. Building consensus around an artifact such as a graph strengthened the need for consensus and thereby strengthened the opportunities for productive conversation. In addition, professional development activities that target building and using specific language were also opportunities for productive learning talk, providing opportunities to negotiate the deep meaning of words and concepts rather then leaving them unexamined. When viewed through the lens of Wenger's Community of Practice (1998) these findings are ways of strengthening the community

  8. Endogenous cross-talk of fungal metabolites.

    Directory of Open Access Journals (Sweden)

    Kevin J Sheridan

    2015-01-01

    Full Text Available Non-ribosomal peptide synthesis in fungi requires a ready supply of proteogenic and non-proteogenic amino acids which are subsequently incorporated into the nascent non-ribosomal peptide via a thiotemplate mechanism catalysed by non-ribosomal peptide synthetases. Substrate amino acids can be modified prior to or during incorporation into the non-ribosomal peptide, or following incorporation into an early stage amino acid-containing biosynthetic intermediate. These post-incorporation modifications involve a range of additional enzymatic activities including but not exclusively, monooxygenases, methyltransferases, epimerases, oxidoreductases and glutathione transferases which are essential to effect biosynthesis of the final non-ribosomal peptide. Likewise, polyketide biosynthesis is directly by polyketide synthase megaenzymes and cluster-encoded ancilliary decorating enzymes. Additionally, a suite of additional primary metabolites, for example: CoA, acetyl CoA, S-adenosylmethionine, glutathione, NADPH, malonyl CoA and molecular oxygen, amongst others are required for non-ribosomal peptide and polyketide synthesis. Clearly these processes must involve exquisite orchestration to facilitate the simultaneous biosynthesis of different types of non-ribosomal peptides, polyketides, and related metabolites requiring identical or similar biosynthetic precursors or co-factors. Moreover, the near identical structures of many natural products within a given family (e.g., ergot alkaloids, along with localization to similar regions within fungi (e.g., conidia suggests that cross-talk may exist, in terms of biosynthesis and functionality. Finally, we speculate if certain biosynthetic steps involved in non-ribosomal peptide and polyketide synthesis play a role in cellular protection or environmental adaptation, and wonder if these enzymatic reactions are of equivalent importance to the actual biosynthesis of the final metabolite.

    Power talk is a novel concept for communication among control units in MicroGrids (MGs), carried out without a dedicated modem, but by using power electronics that interface the common bus. The information is transmitted by modulating the parameters of the primary control, incurring subtle power deviations that can be detected by other units. In this paper, we develop power talk communication strategies for DC MG systems with arbitrary number of control units that carry out all-to-all communi...

  20. Parents' perspectives on talking to preteenage children about sex.

    2010-03-01

    Although parent-child communication about sex can significantly affect children's sexual behavior, many parents do not talk to their children about sex. Qualitative research can elucidate parents' attitudes toward and experiences with communicating with their children about sex. In 2007, 16 focus groups were conducted with 131 mothers and fathers of children aged 10-12 in three cities in different regions of the United States. Separate groups were conducted for mothers and fathers, and for black, white and Hispanic parents. Content analysis was used to identify core themes and patterns. Parents believed it is important to talk to their children about sex and believed that doing so can be effective, but many had not done so. Primary barriers were parents' perception that their children are too young and not knowing how to talk to their children about the subject. Parents found it easiest to talk to their children about sex if they had a good parent-child relationship, took advantage of opportunities to talk and began having the discussions when their children were very young. Some differences were noted by parents' race, ethnicity, gender and location. Interventions aimed at encouraging parents to talk to their children about sex should enhance parents' understanding of the stages of children's sexual development and focus on the parents of young children. In addition, interventions should support parents in a range of strategies that complement discussions about sex.

  1. Modelling and Analysis of Biochemical Signalling Pathway Cross-talk

    Directory of Open Access Journals (Sweden)

    Robin Donaldson

    2010-02-01

    Full Text Available Signalling pathways are abstractions that help life scientists structure the coordination of cellular activity. Cross-talk between pathways accounts for many of the complex behaviours exhibited by signalling pathways and is often critical in producing the correct signal-response relationship. Formal models of signalling pathways and cross-talk in particular can aid understanding and drive experimentation. We define an approach to modelling based on the concept that a pathway is the (synchronising parallel composition of instances of generic modules (with internal and external labels. Pathways are then composed by (synchronising parallel composition and renaming; different types of cross-talk result from different combinations of synchronisation and renaming. We define a number of generic modules in PRISM and five types of cross-talk: signal flow, substrate availability, receptor function, gene expression and intracellular communication. We show that Continuous Stochastic Logic properties can both detect and distinguish the types of cross-talk. The approach is illustrated with small examples and an analysis of the cross-talk between the TGF-b/BMP, WNT and MAPK pathways.

  2. Why do women engage in fat talk? Examining fat talk using Self-Determination Theory as an explanatory framework.

    2017-03-01

    This study used Self-Determination Theory to examine the motivational processes involved in individuals' engagement in fat talk and its association with unhealthy eating behaviors. Female undergraduate students (N=453) completed an online questionnaire, which assessed general and contextual motivation, importance placed on goals, fat talk, and unhealthy eating behaviors. Structural equation modeling revealed that being generally non-self-determined and placing more importance on extrinsic goals, such as thinness, was associated with fat talk. Fat talk was further associated with non-self-determined motivation for eating regulation, which in turn was associated with unhealthy eating. General self-determination and placing more importance on intrinsic goals, such as health, were not associated with fat talk, but instead, were associated with more adaptive forms of eating regulation and diet quality. Findings further current knowledge on the respective roles of motivation and goals on the engagement in fat talk, and its consequences on eating regulation and behavior.

  6. Salt splitting with ceramic membranes

    Energy Technology Data Exchange (ETDEWEB)

    Kurath, D. [Pacific Northwest National Lab., Richland, WA (United States)

    1996-10-01

    The purpose of this task is to develop ceramic membrane technologies for salt splitting of radioactively contaminated sodium salt solutions. This technology has the potential to reduce the low-level waste (LLW) disposal volume, the pH and sodium hydroxide content for subsequent processing steps, the sodium content of interstitial liquid in high-level waste (HLW) sludges, and provide sodium hydroxide free of aluminum for recycle within processing plants at the DOE complex. Potential deployment sites include Hanford, Savannah River, and Idaho National Engineering Laboratory (INEL). The technical approach consists of electrochemical separation of sodium ions from the salt solution using sodium (Na) Super Ion Conductors (NaSICON). As the name implies, sodium ions are transported rapidly through these ceramic crystals even at room temperatures.

    From Albian to end Cretaceous times, the inboard part of the Santos Basin in Brazil was affected by extension as salt flowed basinwards under the effect of gravity. Salt rollers, flip-flop salt diapirs and the famous Albian Gap were all formed by this process. Outboard of these extensional structures, contraction was taken up in a wide zone of thickened salt where salt collected. The overburden was carried on top of the salt as it flowed down-dip, with up to 40 km of translation recorded in Albian strata. (author)

    Jooste, Pieter L

    2005-01-01

    Marketing of non-iodized salt through unconventional distribution channels is one of the factors weakening the national salt iodization program in South Africa. The aim of this study was therefore to quantify the various sources of household salt, and to relate this information to socio-economic status. Questionnaire information was collected by personal interview during home visits from a multistage, cluster, probability sample of 2164 adults representative of the adult population. Nationally 77.7% of households obtained their table salt from the typical food shops distributing iodized salt. However, in the nine different provinces between 8 and 37.3% of households used unconventional sources, distributing mainly non-iodized salt, to obtain their household salt. These alternative sources include distributors of agricultural salt, small general dealer shops called spaza shops, in peri-urban and rural townships, street vendors and salt saches placed in the packaging of maize meal bags. Country-wide around 30% of low socio-economic households obtained their salt from unconventional sources compared to less than 5% in high socio-economic households, emphasizing the vulnerability of low socio-economic groups to the use of non-iodized salt. Intervention strategies should mobilize all role players involved in unconventional marketing channels of household salt to provide only iodized salt to consumers, as required by law.

    Salting process plays a key role in the preservation and quality of dry-cured meat products. Therefore, an adequate monitoring of salt content during salting is necessary to reach high quality products. Thus, the main objective of this work was to test the ability of low intensity ultrasound to monitor the salting process of pork meat. Cylindrical samples (diameter 36 mm, height 60±10 mm) of Biceps femoris were salted (brine 20% NaCl, w/w) at 2 °C for 1, 2, 4 and 7 days. During salting and at each experimental time, three cylinders were taken in order to measure the ultrasonic velocity at 2 °C. Afterwards, the cylinders were split in three sections (height 20 mm), measuring again the ultrasonic velocity and determining the salt and the moisture content by AOAC standards. In the whole cylinders, moisture content was reduced from 763 (g/kg sample) in fresh samples to 723 (g/kg sample) in samples salted for 7 days, while the maximum salt gain was 37.3 (g/kg sample). Although, moisture and salt contents up to 673 and 118 (g/kg sample) were reached in the sections of meat cylinders, respectively. During salting, the ultrasonic velocity increased due to salt gain and water loss. Thus, significant (pmeat salting processes carried out in the food industry.

    2016-04-01

    This study examined men's perceptions of women engaging in "Fat Talk," a style of conversation that expresses discontent towards one's physical appearance, especially focusing on and criticizing body fat, shape, and weight. Male undergraduates were shown a vignette illustrating a courting scenario wherein the target female's body size was manipulated to be "sexy" and: (a) "lean," (b) "average," or (c) "larger." And to another woman, the men overheard the target female either: (a) self-degrade herself (fat talk) or (b) self-accept herself. As a third independent variable, participants' self esteem was divided into high and low with a median split. Dependent variables included self-created Likert items on his attraction towards the target and perceptions of her health and popularity. Men found the target female to have poorer mental health when he overheard her fat talking versus self-accepting. Further, his desire for a more exclusive committed relationship was stronger when she was described as leaner, especially for the lower self-esteemed men. As a pilot study, this has implications for interventions to decrease women's fat talk and begins research on the dynamic interplay between women's fat talk and heterosexual courtships.

    2016-09-01

    Although past studies have highlighted fat talk as relevant to body image disturbance, the majority of these have only investigated the link between fat talk and body esteem, to the exclusion of other body image constructs. One hundred and ninety-nine women completed an online survey measuring levels of appearance-based comparisons, body surveillance, thin ideal internalization, body esteem, and fat talk (FT-body concerns and FT-body comparisons). Results showed that fat talk made a significant contribution in explaining additional variance in body esteem above the other three body image factors, with FT-body concerns in particular making the highest unique contribution. Hierarchical regression analyses suggest that fat talk should be viewed as an independent psychosocial predictor of body esteem in both theoretical and therapeutic contexts. Future research should explore these relationships from a longitudinal perspective, and also clarify the nuances in the relationships by investigating the nature of women's everyday body image experiences.

    Full Text Available In developed as well as developing countries, the four main factors affecting blood pressure are high salt intake, low potassium intake, overweight, and low physical activity level. This is also true for the increase in blood pressure with advancing age, occurring in all societies. It is now accepted that excess dietary salt raises blood pressure levels, whereas dietary salt reduction reduces blood pressure and prevents vascular complications.(1 The effect of salt on blood pressure is presumably due to the inability of the kidneys to excrete large amounts of salt, as humans are evolutionary adapted to ingest and excrete less than 1 gram of salt per day.(2 In this connection it should be noted that the more important element in common salt (sodium chloride is the sodium ion, and any restrictions applying to common salt also apply to all food items that contain sodium ions, such as sodium glutamate and baking soda.

Thirty-three undergraduate English major students studying at the University of Guilan were assigned to design a composite photographic image by combining images from separate photographic sources, and use it as the stimulus to initiate talking in class. Students’ talks based on their own self-generated photomontage and their peers’ feedback in all classes were video recorded and the transcription was coded for words, syllables, T-units, content and function words. This transcription was used as the basis for analyzing the change in learners’ oral repertoire prior to, and after the experiment with regard to three areas of complexity, accuracy and fluency (CAF triad. The results of repeated measures analysis of variance and also paired samples t-test showed that photomontage had appealing potentials for fluency and accuracy but not for complexity.

  19. Reconsolidated Salt as a Geotechnical Barrier

    2015-11-01

    Salt as a geologic medium has several attributes favorable to long-term isolation of waste placed in mined openings. Salt formations are largely impermeable and induced fractures heal as stress returns to equilibrium. Permanent isolation also depends upon the ability to construct geotechnical barriers that achieve nearly the same high-performance characteristics attributed to the native salt formation. Salt repository seal concepts often include elements of reconstituted granular salt. As a specific case in point, the Waste Isolation Pilot Plant recently received regulatory approval to change the disposal panel closure design from an engineered barrier constructed of a salt-based concrete to one that employs simple run-of-mine salt and temporary bulkheads for isolation from ventilation. The Waste Isolation Pilot Plant is a radioactive waste disposal repository for defense-related transuranic elements mined from the Permian evaporite salt beds in southeast New Mexico. Its approved shaft seal design incorporates barrier components comprising salt-based concrete, bentonite, and substantial depths of crushed salt compacted to enhance reconsolidation. This paper will focus on crushed salt behavior when applied as drift closures to isolate disposal rooms during operations. Scientific aspects of salt reconsolidation have been studied extensively. The technical basis for geotechnical barrier performance has been strengthened by recent experimental findings and analogue comparisons. The panel closure change was accompanied by recognition that granular salt will return to a physical state similar to the halite surrounding it. Use of run-of-mine salt ensures physical and chemical compatibility with the repository environment and simplifies ongoing disposal operations. Our current knowledge and expected outcome of research can be assimilated with lessons learned to put forward designs and operational concepts for the next generation of salt repositories.

  1. Can COSMOTherm Predict a Salting in Effect?

    Toivola, Martta; Prisle, Nønne L; Elm, Jonas; Waxman, Eleanor M; Volkamer, Rainer; Kurtén, Theo

    2017-08-24

    We have used COSMO-RS, a method combining quantum chemistry with statistical thermodynamics, to compute Setschenow constants (K S ) for a large array of organic solutes and salts. These comprise both atmospherically relevant solute-salt combinations, as well as systems for which experimental data are available. In agreement with previous studies on single salts, the Setschenow constants predicted by COSMO-RS (as implemented in the COSMOTherm program) are generally too large compared to experiments. COSMOTherm overpredicts salting out (positive K S ), and/or underpredicts salting in (negative K S ). For ammonium and sodium salts, K S values are larger for oxalates and sulfates, and smaller for chlorides and bromides. For chloride and bromide salts, K S values usually increase with decreasing size of the cation, along the series Pr 4 N + salting in is predicted only for oxalic acid in sodium and ammonium oxalate, and sodium sulfate, solutions. COSMOTherm was thus unable to replicate the experimentally observed salting in of glyoxal in sulfate solutions, likely due to the overestimation of salting out effects. By contrast, COSMOTherm does qualitatively predict the experimentally observed salting in of multiple organic solutes in solutions of alkylaminium salts.

    Accumulating evidence shows an increase in insulin resistance on salt restriction. We compared the effect of low salt diet on insulin resistance in salt-sensitive versus salt-resistant hypertensive subjects. We also evaluated the relationship between salt sensitivity of blood pressure and salt sensitivity of insulin resistance in a multivariate regression model. Studies were conducted after 1 week of high salt (200 mmol per day sodium) and 1 week of low salt (10 mmol per day sodium) diet. Salt sensitivity was defined as the fall in systolic blood pressure>15 mm Hg on low salt diet. The study includes 389 subjects (44% women; 16% blacks; body mass index, 28.5±4.2 kg/m2). As expected, blood pressure was lower on low salt (129±16/78±9 mm Hg) as compared with high salt diet (145±18/86±10 mm Hg). Fasting plasma glucose, insulin, and homeostasis model assessment were higher on low salt diet (95.4±19.4 mg/dL; 10.8±7.3 mIU/L; 2.6±1.9) as compared with high salt diet (90.6±10.8 mg/dL; 9.4±5.8 mIU/L; 2.1±1.4; Psalt-sensitive (n=193) versus salt-resistant (n=196) subjects on either diet. Increase in homeostasis model assessment on low salt diet was 0.5±1.4 in salt-sensitive and 0.4±1.5 in salt-resistant subjects (P=NS). On multivariate regression analysis, change in systolic blood pressure was not associated with change in homeostasis model assessment after including age, body mass index, sex, change in serum and urine aldosterone, and cortisol into the model. We conclude that the increase in insulin resistance on low salt diet is not affected by salt sensitivity of blood pressure. © 2014 American Heart Association, Inc.

    Reconsolidated crushed salt is being considered as a backfilling material placed upon nuclear waste within a salt repository environment. In-depth knowledge of thermal and mechanical properties of the crushed salt as it reconsolidates is critical to thermal/mechanical modeling of the reconsolidation process. An experimental study was completed to quantitatively evaluate the thermal conductivity of reconsolidated crushed salt as a function of porosity and temperature. The crushed salt for this study came from the Waste Isolation Pilot Plant (WIPP). In this work the thermal conductivity of crushed salt with porosity ranging from 1% to 40% was determined from room temperature up to 300°C, using two different experimental methods. Thermal properties (including thermal conductivity, thermal diffusivity and specific heat) of single-crystal salt were determined for the same temperature range. The salt was observed to dewater during heating; weight loss from the dewatering was quantified. The thermal conductivity of reconsolidated crushed salt decreases with increasing porosity; conversely, thermal conductivity increases as the salt consolidates. The thermal conductivity of reconsolidated crushed salt for a given porosity decreases with increasing temperature. A simple mixture theory model is presented to predict and compare to the data developed in this study.

  16. Talking Circles for Adolescent Girls in an Urban High School

    Ann Schumacher

    2014-10-01

    Full Text Available Restorative Practices (RP in schools is a new and emerging field. Meeting in Circles to build friendships, develop emotional literacy skills, resolve conflict, or learn interactively are some of the core components of these programs. This article describes a 2-year study of 12 weekly Talking Circles organized under the auspices of a RP program in an urban high school with 60 adolescent girls. Primary data sources included 257 hr of participant observations in Talking Circles and individual, semi-structured interviews with 31 students. The Relational Cultural model, rooted in the work of Jean Baker Miller, served as the conceptual framework for understanding teens’ interactions within the Circle’s unique set of social conditions in a school environment. Findings demonstrated that Talking Circles provided a safe space for peers helping peers, and that the girls improved their listening, anger management, and empathic skills, which led to greater self-efficacy. It appears that Talking Circles could provide another venue for developing social-emotional literacy skills and growth-fostering relationships in schools.

  18. Suprasegmental information affects processing of talking faces at birth.

    Science.gov (United States)

    Guellai, Bahia; Mersad, Karima; Streri, Arlette

    2015-02-01

    From birth, newborns show a preference for faces talking a native language compared to silent faces. The present study addresses two questions that remained unanswered by previous research: (a) Does the familiarity with the language play a role in this process and (b) Are all the linguistic and paralinguistic cues necessary in this case? Experiment 1 extended newborns' preference for native speakers to non-native ones. Given that fetuses and newborns are sensitive to the prosodic characteristics of speech, Experiments 2 and 3 presented faces talking native and nonnative languages with the speech stream being low-pass filtered. Results showed that newborns preferred looking at a person who talked to them even when only the prosodic cues were provided for both languages. Nonetheless, a familiarity preference for the previously talking face is observed in the "normal speech" condition (i.e., Experiment 1) and a novelty preference in the "filtered speech" condition (Experiments 2 and 3). This asymmetry reveals that newborns process these two types of stimuli differently and that they may already be sensitive to a mismatch between the articulatory movements of the face and the corresponding speech sounds.

  1. Representasi Pembawa Acara Program Talk Show di Televisi Indonesia

    2013-10-01

    Full Text Available Presentation of talk show host program has been known to be intelligent, smart, and is able to direct the conversation in the program well. The presentation is in line with the view of talk show programs packed seriously as a journalistic genre program with emphasis on the truth of the facts or information conveyed. However, in recent years there are different representations associated with the talk show host of the program. The representation shows that a talk show host is not such intelligent and smart, and is not able to direct the conversation in the program properly. The existence of this representation is consistent with the theory of social construction assuming that mass media play a major role in shaping the social reality in the society. As of this writing, the audience receives social reality as a representation. Like the previous presentation, as the television has broadcasted for a long time, people feel that the reality is normative and ideal conditions for them. Public realize that the social reality was only the reconstruction of the television when TV presents a representation of another social reality. Nevertheless, whatever the social reality that is deliberately made or reconstructed by the media, including television, in fact everything is a reality that is deliberately created just for the sake of the manager or owner of the television station.

  5. Early Holocene Great Salt Lake

    Science.gov (United States)

    Oviatt, Charles G.; Madsen, David B.; Miller, David; Thompson, Robert S.; McGeehin, John P.

    2015-01-01

    Shorelines and surficial deposits (including buried forest-floor mats and organic-rich wetland sediments) show that Great Salt Lake did not rise higher than modern lake levels during the earliest Holocene (11.5–10.2 cal ka BP; 10–9 14C ka BP). During that period, finely laminated, organic-rich muds (sapropel) containing brine-shrimp cysts and pellets and interbedded sodium-sulfate salts were deposited on the lake floor. Sapropel deposition was probably caused by stratification of the water column — a freshwater cap possibly was formed by groundwater, which had been stored in upland aquifers during the immediately preceding late-Pleistocene deep-lake cycle (Lake Bonneville), and was actively discharging on the basin floor. A climate characterized by low precipitation and runoff, combined with local areas of groundwater discharge in piedmont settings, could explain the apparent conflict between evidence for a shallow lake (a dry climate) and previously published interpretations for a moist climate in the Great Salt Lake basin of the eastern Great Basin.

  6. Cross-talk between Phosphate Starvation and Other Environmental Stress Signaling Pathways in Plants.

    Science.gov (United States)

    Baek, Dongwon; Chun, Hyun Jin; Yun, Dae-Jin; Kim, Min Chul

    2017-10-01

    The maintenance of inorganic phosphate (Pi) homeostasis is essential for plant growth and yield. Plants have evolved strategies to cope with Pi starvation at the transcriptional, post-transcriptional, and post-translational levels, which maximizes its availability. Many transcription factors, miRNAs, and transporters participate in the Pi starvation signaling pathway where their activities are modulated by sugar and phytohormone signaling. Environmental stresses significantly affect the uptake and utilization of nutrients by plants, but their effects on the Pi starvation response remain unclear. Recently, we reported that Pi starvation signaling is affected by abiotic stresses such as salt, abscisic acid, and drought. In this review, we identified transcription factors, such as MYB, WRKY, and zinc finger transcription factors with functions in Pi starvation and other environmental stress signaling. In silico analysis of the promoter regions of Pi starvation-responsive genes, including phosphate transporters, microRNAs, and phosphate starvation-induced genes, suggest that their expression may be regulated by other environmental stresses, such as hormones, drought, cold, heat, and pathogens as well as by Pi starvation. Thus, we suggest the possibility of cross-talk between Pi starvation signaling and other environmental stress signaling pathways.

  8. Comparative physiology of salt and water stress.

    Science.gov (United States)

    Munns, R.

    2002-02-01

    Plant responses to salt and water stress have much in common. Salinity reduces the ability of plants to take up water, and this quickly causes reductions in growth rate, along with a suite of metabolic changes identical to those caused by water stress. The initial reduction in shoot growth is probably due to hormonal signals generated by the roots. There may be salt-specific effects that later have an impact on growth; if excessive amounts of salt enter the plant, salt will eventually rise to toxic levels in the older transpiring leaves, causing premature senescence, and reduce the photosynthetic leaf area of the plant to a level that cannot sustain growth. These effects take time to develop. Salt-tolerant plants differ from salt-sensitive ones in having a low rate of Na+ and Cl-- transport to leaves, and the ability to compartmentalize these ions in vacuoles to prevent their build-up in cytoplasm or cell walls and thus avoid salt toxicity. In order to understand the processes that give rise to tolerance of salt, as distinct from tolerance of osmotic stress, and to identify genes that control the transport of salt across membranes, it is important to avoid treatments that induce cell plasmolysis, and to design experiments that distinguish between tolerance of salt and tolerance of water stress.

  10. Salt splitting using ceramic membranes

    Energy Technology Data Exchange (ETDEWEB)

    Kurath, D.E. [Pacific Northwest National Lab., Richland, WA (United States)

    1997-10-01

    Many radioactive aqueous wastes in the DOE complex have high concentrations of sodium that can negatively affect waste treatment and disposal operations. Sodium can decrease the durability of waste forms such as glass and is the primary contributor to large disposal volumes. Waste treatment processes such as cesium ion exchange, sludge washing, and calcination are made less efficient and more expensive because of the high sodium concentrations. Pacific Northwest National Laboratory (PNNL) and Ceramatec Inc. (Salt Lake City UT) are developing an electrochemical salt splitting process based on inorganic ceramic sodium (Na), super-ionic conductor (NaSICON) membranes that shows promise for mitigating the impact of sodium. In this process, the waste is added to the anode compartment, and an electrical potential is applied to the cell. This drives sodium ions through the membrane, but the membrane rejects most other cations (e.g., Sr{sup +2}, Cs{sup +}). The charge balance in the anode compartment is maintained by generating H{sup +} from the electrolysis of water. The charge balance in the cathode is maintained by generating OH{sup {minus}}, either from the electrolysis of water or from oxygen and water using an oxygen cathode. The normal gaseous products of the electrolysis of water are oxygen at the anode and hydrogen at the cathode. Potentially flammable gas mixtures can be prevented by providing adequate volumes of a sweep gas, using an alternative reductant or destruction of the hydrogen as it is generated. As H{sup +} is generated in the anode compartment, the pH drops. The process may be operated with either an alkaline (pH>12) or an acidic anolyte (pH <1). The benefits of salt splitting using ceramic membranes are (1) waste volume reduction and reduced chemical procurement costs by recycling of NaOH; and (2) direct reduction of sodium in process streams, which enhances subsequent operations such as cesium ion exchange, calcination, and vitrification.

  19. I'm not just fat, I'm old: has the study of body image overlooked "old talk"?

    Research indicates that body dissatisfaction is correlated with and often predictive of both physical and mental health problems. "Fat talk," a well-studied form of body image talk in adolescents and university-aged women, has been implicated as contributing to body dissatisfaction and mediating the relationship between body dissatisfaction and other mental health problems. Limited research, however, has investigated fat talk across the female lifespan. Further, consistent with most body image research, fat talk research solely focuses on the thin dimension of idealized female attractiveness, even though other dimensions may contribute to body dissatisfaction in women. The current study investigated whether or not "old talk," a hereto un-described form of body image talk, appears to be a parallel, but distinct, form of body image talk that taps into the young dimension of the thin-young-ideal standard of female beauty. An international, internet sample of women (aged 18-87, N = 914) completed questionnaires aimed at assessing fat talk, old talk, body image disturbance, and eating disorder pathology. Results indicated that both fat talk and old talk were reported by women across the lifespan, although they evidenced different trajectories of frequency. Like fat talk, old talk was significantly correlated with body image disturbance and eating disorder pathology, albeit at a lower rate than fat talk in the total sample. Old talk was more highly correlated with ageing appearance anxiety than fat talk, and the correlation between old talk and body image disturbance and ED pathology increased with women's ages. Results suggest that old talk is a form of body image talk that is related to but distinct from fat talk. Old talk appears to be similarly problematic to fat talk for women whose age increases their deviation from the thin-young-ideal. Further research into the phenomenon of old talk is warranted as is increased attention to fat talk across the full lifespan

    The Makgadikgadi Salt Pan of Botswana, an ancient lake bed, (19.0S, 26.0E) is one of the largest features in Botswana visible from orbit. Any water that spills out of the Okavango Swamplands flows into the Makagadikgadi where it evaporates. An ancient beach line can be seen as a smooth line around the west side of the pan and to the south, the Orapa diamond mine is seen as a small rectangle. Far to the east, can be seen the Great Dike of Zimbabwe.

  1. Osteopontin activates the diabetes-associated potassium channel TALK-1 in pancreatic β-cells.

    Directory of Open Access Journals (Sweden)

    Matthew T Dickerson

    Full Text Available Glucose-stimulated insulin secretion (GSIS relies on β-cell Ca2+ influx, which is modulated by the two-pore-domain K+ (K2P channel, TALK-1. A gain-of-function polymorphism in KCNK16, the gene encoding TALK-1, increases risk for developing type-2 diabetes. While TALK-1 serves an important role in modulating GSIS, the regulatory mechanism(s that control β-cell TALK-1 channels are unknown. Therefore, we employed a membrane-specific yeast two-hybrid (MYTH assay to identify TALK-1-interacting proteins in human islets, which will assist in determining signaling modalities that modulate TALK-1 function. Twenty-one proteins from a human islet cDNA library interacted with TALK-1. Some of these interactions increased TALK-1 activity, including intracellular osteopontin (iOPN. Intracellular OPN is highly expressed in β-cells and is upregulated under pre-diabetic conditions to help maintain normal β-cell function; however, the functional role of iOPN in β-cells is poorly understood. We found that iOPN colocalized with TALK-1 in pancreatic sections and coimmunoprecipitated with human islet TALK-1 channels. As human β-cells express two K+ channel-forming variants of TALK-1, regulation of these TALK-1 variants by iOPN was assessed. At physiological voltages iOPN activated TALK-1 transcript variant 3 channels but not TALK-1 transcript variant 2 channels. Activation of TALK-1 channels by iOPN also hyperpolarized resting membrane potential (Vm in HEK293 cells and in primary mouse β-cells. Intracellular OPN was also knocked down in β-cells to test its effect on β-cell TALK-1 channel activity. Reducing β-cell iOPN significantly decreased TALK-1 K+ currents and increased glucose-stimulated Ca2+ influx. Importantly, iOPN did not affect the function of other K2P channels or alter Ca2+ influx into TALK-1 deficient β-cells. These results reveal the first protein interactions with the TALK-1 channel and found that an interaction with iOPN increased

  2. Impact of slope inclination on salt accumulation

    2017-04-01

    Field measurements indicated on high variability in salt accumulation along natural and cultivated slopes, even for relatively homogeneous soil conditions. It was hypothesised that slope inclination has an impact on the location of salt accumulation along the slope. A set of laboratory experiments and numerical models were used to explore the impact of slope inclination on salt accumulation. It was shown, experimentally, that for conditions of saline water source at the lower boundary of the slope - salt accumulates in low concentrations and homogeneously along the entire slope, for moderate slopes. However, as inclination increases high salt concentrations were observed at the upper parts of the slope, leaving the lower parts of the slope relatively free of salt. The traditional flow and transport models did not predict the experimental observations as they indicated also for the moderate slopes on salt accumulation in the elevated parts of the slope, away of the saline water source. Consequently - a conceptual model was raised to explain the laboratory observations. It was suggested that the interactions between slope angle, evaporation rates, hydraulic conductivity of the medium and distribution of wetness along the slope affect the saline water flow path through the medium. This lead to preferential flow path close to the soil-atmosphere interface for the steep slopes, which leads to constant wash of the salts from the evaporation front upward towards the slope upper parts, whereas for the moderate slopes, flow path is below the soil-atmosphere interface, therefore salt that accumulates at the evaporation front is not being transported upward. Understanding of salt dynamics along slopes is important for agricultural and natural environments, as well as for civil engineering purposes. Better understanding of the salt transport processes along slopes will improve our ability to minimize and to cope with soil salinization processes. The laboratory experiments and

    Great Salt Lake is the largest hypersaline lake in the Western Hemisphere and the fourth largest terminal lake in the world (Figure 1). The open water and adjacent wetlands of the Great Salt Lake ecosystem support millions of migratory waterfowl and shorebirds from throughout the Western Hemisphere [Aldrich and Paul, 2002]. In addition, the area is of important economic value: Brine shrimp (Artemia franciscana) residing in Great Salt Lake support an aquaculture shrimp cyst industry with annual revenues as high as $60 million.

  4. Macroevolutionary patterns of salt tolerance in angiosperms

    Science.gov (United States)

    Bromham, Lindell

    2015-01-01

    Background Halophytes are rare, with only 0·25 % of angiosperm species able to complete their life cycle in saline conditions. This could be interpreted as evidence that salt tolerance is difficult to evolve. However, consideration of the phylogenetic distribution of halophytes paints a different picture: salt tolerance has evolved independently in many different lineages, and halophytes are widely distributed across angiosperm families. In this Viewpoint, I will consider what phylogenetic analysis of halophytes can tell us about the macroevolution of salt tolerance. Hypothesis Phylogenetic analyses of salt tolerance have shown contrasting patterns in different families. In some families, such as chenopods, salt tolerance evolved early in the lineage and has been retained in many lineages. But in other families, including grasses, there have been a surprisingly large number of independent origins of salt tolerance, most of which are relatively recent and result in only one or a few salt-tolerant species. This pattern of many recent origins implies either a high transition rate (salt tolerance is gained and lost often) or a high extinction rate (salt-tolerant lineages do not tend to persist over macroevolutionary timescales). While salt tolerance can evolve in a wide range of genetic backgrounds, some lineages are more likely to produce halophytes than others. This may be due to enabling traits that act as stepping stones to developing salt tolerance. The ability to tolerate environmental salt may increase tolerance of other stresses or vice versa. Conclusions Phylogenetic analyses suggest that enabling traits and cross-tolerances may make some lineages more likely to adapt to increasing salinization, a finding that may prove useful in assessing the probable impact of rapid environmental change on vegetation communities, and in selecting taxa to develop for use in landscape rehabilitation and agriculture.

We show that the coefficients of the linear combinations, representing equivalent channel gains, depend on the virtual resistances of the primary control loops......, implying that they can be modified such that effective received signal-to-noise ratio (SNR) is increased. On the other hand, we investigate the constraints that power talk incurs on the supplied power deviations.

In this regard, we develop an optimization approach to find the set of controllable virtual resistances that maximize SNR under the constraints on the supplied power deviations....

    Liao, Yun; Han, Zhu

    2016-01-01

    This brief focuses on the use of full-duplex radio in cognitive radio networks, presenting a novel spectrum sharing protocol that allows the secondary users to simultaneously sense and access the vacant spectrum. This protocol, called “Listen-and-talk” (LAT), is evaluated by both mathematical analysis and computer simulations in comparison with other existing protocols, including the listen-before-talk protocol. In addition to LAT-based signal processing and resource allocation, the brief discusses techniques such as spectrum sensing and dynamic spectrum access. The brief proposes LAT as a suitable access scheme for cognitive radio networks, which can support the quality-of-service requirements of these high priority applications. Fundamental theories and key techniques of cognitive radio networks are also covered. Listen and Talk: Full-duplex Cognitive Radio Networks is designed for researchers, developers, and professionals involved in cognitive radio networks. Advanced-level students studying signal pr...

    The United States has the highest incarceration rate of any nation in the world-more than 700 people per 100,000. For this reason alone, clinicians practicing in the US should be aware of the numerous ways in which incarceration adversely affects the health of individuals, their families, and communities. While we clinicians are taught how to discuss ways that culture, religion, or sexuality can affect health outcomes, we are not instructed on how to talk about incarceration history with patients when it might be affecting their health, as highlighted in the case scenario. Here I present a "structural vulnerability" screen, a theoretical approach that clinics or individuals can take to better understand how structures of power (i.e., mass incarceration) directly and indirectly affect our patients. I also offer practical tips on how to talk to patients about incarceration history and why it matters for good health. © 2017 American Medical Association. All Rights Reserved.

    Disturbed Wnt signaling has been implicated in numerous diseases, including type 2 diabetes and the metabolic syndrome. In the present study, we have investigated cross-talk between insulin and Wnt signaling pathways using preadipocytes with and without knockdown of the Wnt co-receptors LRP5...... are insulin/IGF-1 receptor-dependent and are lost in insulin/IGF-1 receptor double knock-out cells. Conversely, in LRP5 knockdown preadipocytes, insulin-induced phosphorylation of IRS1, Akt, GSK3β, and ERK1/2 is highly reduced. This effect is specific to insulin, as compared with IGF-1, stimulation...... and appears to be due to an inducible interaction between LRP5 and the insulin receptor as demonstrated by co-immunoprecipitation. These data demonstrate that Wnt and insulin signaling pathways exhibit cross-talk at multiple levels. Wnt induces phosphorylation of Akt, ERK1/2, and GSK3β, and this is dependent...

  10. Optimization of an Image-Based Talking Head System

    Directory of Open Access Journals (Sweden)

    Kang Liu

    2009-01-01

    Full Text Available This paper presents an image-based talking head system, which includes two parts: analysis and synthesis. The audiovisual analysis part creates a face model of a recorded human subject, which is composed of a personalized 3D mask as well as a large database of mouth images and their related information. The synthesis part generates natural looking facial animations from phonetic transcripts of text. A critical issue of the synthesis is the unit selection which selects and concatenates these appropriate mouth images from the database such that they match the spoken words of the talking head. Selection is based on lip synchronization and the similarity of consecutive images. The unit selection is refined in this paper, and Pareto optimization is used to train the unit selection. Experimental results of subjective tests show that most people cannot distinguish our facial animations from real videos.

    2006-01-01

    This study examined the relation between the amount of mathematical input in the speech of preschool or day-care teachers and the growth of children's conventional mathematical knowledge over the school year. Three main findings emerged. First, there were marked individual differences in children's conventional mathematical knowledge by 4 years of age that were associated with socioeconomic status. Second, there were dramatic differences in the amount of math-related talk teachers provided. Third, and most important, the amount of teachers' math-related talk was significantly related to the growth of preschoolers' conventional mathematical knowledge over the school year but was unrelated to their math knowledge at the start of the school year.

    2012-05-01

    Defining and describing health has traditionally been the role of medical experts. Although a rich literature has recently established the importance of lay accounts of health, one important gap relates to gay men's accounts of health. Data from 11 focus groups involving 45 gay men were thematically analyzed to investigate gay men's views of health. Two contrasting positions on a possible relationship between sexuality and health-there is no link or there is a definite link-were identified. In addition, five key ways gay men talked about health were identified: health is the absence of disease, is functional ability, is fitness and exercise, is psychological, and is multifaceted. Although there are similarities in the ways gay and other men talk about health, important differences exist, which suggest that issues of sexuality need to be considered by health policy and service planners so that responsive health services can be provided.

    To gain confidence in the predictive capability of numerical models, experimental validation must be performed to ensure that parameters and processes are correctly simulated. The laboratory investigations presented herein aim to address knowledge gaps for heat-generating nuclear waste (HGNW) disposal in bedded salt that remain after examination of prior field and laboratory test data. Primarily, we are interested in better constraining the thermal, hydrological, and physicochemical behavior of brine, water vapor, and salt when moist salt is heated. The target of this work is to use run-of-mine (RoM) salt; however during FY2015 progress was made using high-purity, granular sodium chloride.

    2012-04-01

    The amounts of sodium chloride in the formulation of a variety of foods like bakery, meats and dairy foods, ready meals, sauces and snacks, are relatively large and thus, have a strong contribution on the salt dietary intake. There is a clear demand by the consumers and medical associations to reduce the salt content in foods. Different strategies have been proposed and most of them consist of the replacement of sodium chloride by other salts and the addition of other substances for an acceptable sensory quality. The recent patents for salt reduction and their applications in foods are reviewed in this manuscript.

    2011-06-01

    To provide an overview of national salt reduction initiatives around the world, describe core characteristics and develop a framework for future strategy development. National strategies were identified from existing reviews and from searches of the literature and relevant websites. Standardized information was extracted about governance and strategy development, baseline assessments and monitoring and implementation. Thirty-two country salt reduction initiatives were identified. The majority of activity was in Europe (19 countries). Most countries (27) had maximum population salt intake targets, ranging from 5 to 8 g/person per day. Twenty-six of the 32 strategies were led by government, five by nongovernment organizations and one by industry. Twenty-eight countries had some baseline data on salt consumption and 18 had data on sodium levels in foods. Twenty-eight countries were working with the food industry to reduce salt in foods, 10 had front-of-pack labelling schemes and 28 had consumer awareness or behaviour change programs. Five countries had demonstrated an impact, either on population salt consumption, salt levels in foods or consumer awareness. These strategies were led by government and were multifaceted including food reformulation, consumer awareness initiatives and labelling actions. This is the first review to concisely summarize the most important elements of the many existing salt reduction programmes and highlight the characteristics most likely to be important to programme efficacy. For most countries, implementing a national salt reduction programme is likely to be one of simplest and most cost-effective ways of improving public health.

    Plants exhibit a variety of responses to abiotic stresses that enable them to tolerate and survive adverse conditions. As we learn more about the signalling pathways leading to these responses, it is becoming clear that they constitute a network that is interconnected at many levels. In this article, we discuss the 'cross-talk' between different signalling pathways and question whether there are any truly specific abiotic stress signalling responses.

  6. Positioning Guests in a Maybrit Illner Talk Show

    Directory of Open Access Journals (Sweden)

    Reinhold Schmitt

    2015-12-01

    Full Text Available In this paper we analyze techniques applied by the producers of a talk show in order to position the talk show guests as relevant participants with respect to the subject of fiscal evasion by celebrities. We analyze how the producers succeed in positioning their guests right from the beginning as prototypical representatives. This positioning is achieved through the coordination of a voice from offstage and the management of the cameras when the guests first appear on screen. Two of five guest introductions are analyzed in detail. The two presented guests demonstrate a clearly antagonistic relationship and their introduction is immediately consecutive. We have reconstructed the introduction of all five guests in detail which resulted in the identification of a network of positions. Unfortunately we cannot present all of our analyses here due to the lack of space. At the positional network's center lies the thematic and personal "antagonism" which we reconstructed. At the periphery we have four representatives of societally relevant positions who contribute to the topic of the talk show. The four guests respectively represent jurisdiction, politics, and ethics via a lay perspective, psychology and theology. The analysis is theoretically framed by the multimodal notion of "positioning" and "recipient design", while the applied methodology is multimodal interaction analysis.

  7. Host-pathogen interactions: the seduction of molecular cross talk.

    Science.gov (United States)

    Sansonetti, P

    2002-05-01

    Bacterial pathogens have evolved two major strategies to colonise the intestinal epithelium. Adherent microorganisms bind to the apical pole of the intestinal epithelium, whereas invasive microorganisms disrupt and invade the epithelium. Recognition of the genetic bases of bacterial pathogenicity and analysis of the molecular cross talks established between pathogens and their mammalian target cells have illuminated this diversity of interactions. We have compared the strategies of enteroinvasive pathogens, with emphasis on bacterial species such as Shigella, Yersinia, and Salmonella, that represent paradigms of interaction. Cross talks leading to alteration of the epithelial cell actin cytoskeleton appear as a recurrent theme during entry and dissemination into epithelial cells. Other cross talks alter the trafficking of cellular vesicles and induce changes in the intracellular compartment in which they reside, thus creating niches favourable to bacterial survival and growth. Finally, a variety of strategies also exist to deal with other components of the epithelial barrier, such as macrophages. Pro-phagocytic, anti-phagocytic, and pro-apoptotic processes appear to be of particular importance.

  8. Effects of salting-in interactions on macromolecule diffusiophoresis and salt osmotic diffusion.

    Science.gov (United States)

    McAfee, Michele S; Annunziata, Onofrio

    2015-02-03

    Macromolecule diffusiophoresis (i.e., macromolecule migration induced by a salt concentration gradient) in water and salt osmotic diffusion (i.e., salt migration induced by a macromolecule concentration gradient) are two cross-diffusion mechanisms caused by macromolecule-salt interactions. We investigated the effect of salting-in interactions on the behavior of these two cross-diffusion mechanisms. Our results are distinct from those previously obtained in the case of salting-out interactions. Cross-diffusion was experimentally characterized by Rayleigh interferometry at 25 °C. Specifically, multicomponent diffusion coefficients were measured for a neutral polymer, polyethylene glycol (molar mass, 20 kg/mol), in aqueous solutions of three thiocyanate salts (NaSCN, KSCN, and NH₄SCN) as a function of salt concentration at low polymer concentration (0.5% w/w). Our results on salt osmotic diffusion, which were qualitatively different from those previously obtained for salting-out salts, were used to quantitatively characterize the strength of salting-in interactions. The behavior of polymer diffusiophoresis as a function of salt concentration and cation type reveals that polymer chains have an extrinsic negative charge, consistent with anion binding being the cause of salting-in interactions. To quantitatively examine the effect of anion binding on salt osmotic diffusion and polymer diffusiophoresis, we developed a theoretical model based on the linear laws of nonequilibrium thermodynamics for diffusion, the Scatchard binding model, and particle electrophoresis. This work contributes to the understanding of the multifaceted effects of molecular interactions on cross-diffusion mechanisms, salting-in interactions, and the Hofmeister series.

    The 2002 Winter Olympics are hosted by Salt Lake City at several venues within the city, in nearby cities, and within the adjacent Wasatch Mountains. This anaglyph image provides a stereoscopic map view of north central Utah that includes all of these Olympic sites. In the south, next to Utah Lake, Provo hosts the ice hockey competition. In the north, northeast of the Great Salt Lake, Ogden hosts curling and the nearby Snowbasin ski area hosts the downhill events. In between, southeast of the Great Salt Lake, Salt Lake City hosts the Olympic Village and the various skating events. Further east, across the Wasatch Mountains, the Park City ski resort hosts the bobsled, ski jumping, and snowboarding events. The Winter Olympics are always hosted in mountainous terrain. This view shows the dramatic landscape that makes the Salt Lake City region a world-class center for winter sports.The stereoscopic effect of this anaglyph was created by first draping a Landsat satellite image over a Shuttle Radar Topography Mission digital elevation model and then generating two differing perspectives, one for each eye. When viewed through special glasses, the result is a vertically exaggerated view of Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and will substantially help in analyzing the large and growing Landsat image archive, managed by the U.S. Geological Survey (USGS).Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994.

  11. What help can you get talking to somebody?’ Explaining class differences in the use of talking treatments.

    Talking treatments are underused in England by working-class people: their higher rates of common mental disorders compared with their middle-class counterparts are not matched by an increased use of these treatments. Given that,overall, talking treatments are effective in tackling depression and anxiety,understanding their underuse is important. Based upon semi-structured interview data I argue that a framework centred on individuals' cultural dispositions towards treatment can help with this task. Following Bourdieu, such dispositions can be traced to social structural conditioning factors, together comprising the habitus. Four key dispositions emerge from the data: verbalisation and introspection, impetus for emotional health, relation to medical authority and practical orientation to the future. In turn, these dispositions are rooted in the material, health, occupational and educational characteristics of working-class circumstances. Tracing these circumstances offers suggestions for increasing the use of this service.

  12. Social likeability, conformity, and body talk: Does fat talk have a normative rival in female body image conversations?

    Tompkins, K Brooke; Martz, Denise M; Rocheleau, Courtney A; Bazzini, Doris G

    2009-09-01

    Fat talk, dialogues among women involving negative body-focused discussions, was studied as a function of conformity and social likeability through the use of four vignettes depicting young women in conversation. Using a 2 (body presentation style of the group: negative or positive)x2 (body presentation style of the target, Jenny: negative or positive) factorial design, 215 college women (92.1% non-Hispanic Caucasian) read one of four vignettes in a classroom setting and made ratings on a social likeability scale. Participants' personal ratings of Jenny's likeability were higher when she spoke positively about her body, whereas they expected the other group members in the vignette to like Jenny more when she conformed to the group's body presentation style. This study is the first to support two competing norms for women's body image-the existing norm to fat talk versus a newly documented norm that some women like others who express body acceptance.

    Within Western cultural traditions, the idea that parents should talk about the death of their child with each other is deeply rooted. However, across bereaved parent couples there are wide variations in communication about their grief with each other. In this study, we explored the experiences of bereaved couples related to the process of talking and not talking. We used a thematic coding approach to analyze 20 interviews with 26 bereaved parents (11 interviewed as couples, four as individuals). Four main meanings emerged out of our analysis: not talking because of the inadequacy and pointlessness of words in grief, not talking as a way to regulate emotions in daily life, not talking as an expression of a personal, intimate process, and not talking because the partner has the same loss but a different grief process. In addition, we found that the process of talking and not talking can partly be understood as an emotional responsive process on an intrapersonal and interpersonal level. In this process partners search for a bearable distance from their own grief and their partner's, and attune with their relational context. A better understanding of this process is sought in a dialectical approach, emphasizing the value of both talking and not talking in a tense relationship with each other. Implications for clinical work are described. © 2017 Family Process Institute.

  15. Who is most likely to fat talk? A social comparison perspective.

    Corning, Alexandra F; Gondoli, Dawn M

    2012-09-01

    Negative talk about food, weight, or the body that occurs commonly among women--fat talk--is gaining increasing attention. Whereas its negative eating pathology and body esteem correlates have received continued empirical validation, what is not yet known is who is most likely to fat talk. We propose that social comparison processes underlie and motivate much of fat talk. In a sample of 143 college women, we found evidence for the role of social comparison. First, having a stronger tendency to socially compare directly predicts fat talk. Second, as a woman's body image concerns increase, her likelihood of engaging in fat talk increases, and this is intensified if she has a greater tendency to socially compare. Finally, social comparison propensity begins to exert its exacerbating effects at surprisingly low levels of body image concern. Results are discussed in terms of the advantages of using a social comparison perspective to better understand fat talk. Copyright © 2012 Elsevier Ltd. All rights reserved.

    It is well known that salinity reduces cadmium toxicity in halophytes. However, the possible interference of Cd with the mechanisms of salt tolerance is poorly explored. The aim of this study was to see whether Cd affects salt tolerance mechanisms in the halophyte Sesuvium portulacastrum. S. portulacastrum plants obtained from cuttings were grown in hydroponics for 3 weeks and then exposed to low (0.09 mM) or moderate (200 mM) NaCl concentrations, alone or in combination with 25 μM CdCl 2 . Microscopy observation revealed two strategies of salt tolerance: euhalophytism and secretion of salt by bladder cells. Cadmium exposure hardly influenced the total leaf Na + concentrations. However, Cd supply delayed the salt-induced upregulation of AHA1 (plasma membrane H + -ATPase 1) and SOS1 (plasma membrane Na + transporter "Salt Overly Sensitive 1"), genes that are essential for salt tolerance. Moreover, Cd induced the activation of BADH, coding for betaine aldehyde dehydrogenase, indicating enhanced osmotic stress due to Cd. Sodium-green fluorescence in protoplasts from plants grown with low or high NaCl, alone or in combination with Cd, revealed higher Na + concentrations in the cytoplasm of Cd-exposed plants. Taken together the results indicate interference of Cd with salt tolerance mechanisms in S. portulacastrum. This may have consequences for the efficient use of halophytes in phytoremediation of Cd-contaminated saline soils. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

  6. Whitecaps, sea-salt aerosols, and climate

    Science.gov (United States)

    Anguelova, Magdalena Dimitrova

    Oceanic whitecaps are the major source of sea-salt aerosols. Because these aerosols are dominant in remote marine air, they control the radiative properties of the clean background atmosphere by scattering sunlight, changing cloud properties and lifetime, and providing media for chemical reactions. Including sea-salt effects in climate models improves predictions, but simulating their generation is first necessary. To make the sea-salt generation function currently used in climate models more relevant for aerosol investigations, this study proposes two modifications. First, the conventional relation between whitecap coverage, W, and the 10-meter wind speed, U10, used in typical generation functions is expanded to include additional factors that affect whitecaps and sea-salt aerosol formation. Second, the sea-salt generation function is extended to smaller sizes; sea-salt aerosol with initial radii from 0.4 to 20 mum can now be modeled. To achieve these goals, this thesis develops a new method for estimating whitecap coverage on a global scale using satellite measurements of the brightness temperature of the ocean surface. Whitecap coverage evaluated with this method incorporates the effects of atmospheric stability, sea-surface temperature, salinity, wind fetch, wind duration, and the amount of surface-active material. Assimilating satellite-derived values for whitecap coverage in the sea-salt generation function incorporates the effects of all environmental factors on sea-salt production and predicts realistic sea-salt aerosol loadings into the atmosphere. An extensive database of whitecap coverage and sea-salt aerosol fluxes has been compiled with the new method and is used to investigate their spatial and temporal characteristics. The composite effect of all environmental factors suggests a more uniform latitudinal distribution of whitecaps and sea-salt aerosols than that predicted from wind speed alone. The effect of sea-surface temperature, TS, is

    Heart failure (HF) is a complex syndrome that involves changes in behavioral, neural and endocrine regulatory systems. Dietary salt restriction along with pharmacotherapy is considered an essential component in the effective management of symptomatic HF patients. However, it is well recognized that HF patients typically have great difficulty in restricting sodium intake. We hypothesized that under HF altered activity in systems that normally function to regulate body fluid and cardiovascular homeostasis could produce an increased preference for the taste of salt. Therefore, this study was conducted to evaluate the perceived palatability (defined as salt preference) of food with different concentrations of added salt in compensated chronically medicated HF patients and comparable control subjects. Healthy volunteers (n=25) and medicated, clinically stable HF patients (n=38, NYHA functional class II or III) were interviewed and given an evaluation to assess their preferences for different amounts of saltiness. Three salt concentrations (0.58, 0.82, and 1.16 g/100 g) of bean soup were presented to the subjects. Salt preference for each concentration was quantified using an adjective scale (unpleasant, fair or delicious). Healthy volunteers preferred the soup with medium salt concentration (p=0.042), HF patients disliked the low concentration (p<0.001) and preferred the high concentration of salted bean soup (p<0.001). When compared to healthy volunteers, HF patients demonstrated a significantly greater preference for the soup with a high salt concentration (p=0.038). It is concluded that medicated, compensated patients under chronic treatment for HF have an increased preference for salt. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2007-10-01

    Two lab-scale coagulation/microfiltration membrane reactors were used to compare the arsenic removal from drinking water by ferric salt and aluminum salt coagulation/microfiltration process. FeCl3 and Al2(SO4)3 were appointed as the coagulants. The results show that the arsenic removal efficiency of the two processes are almost equal. Arsenic concentration can be lowered from about 100 microg/L to below 10 microg/L and the lowest is 1.68 microg x L(-1). All of the turbidity of the treated water is less than 0.1 NTU. The concentrations of ferric, aluminum and SO4(2-) of the treated water are entirely satisfied the standard of drinking water. After treated by ferric salt process, pH value of the treated water is increased about 0.5. However, aluminum salt process does not change pH of the drinking water. The concentration ratio of the ferric salt process is 1,791 which is about 2.54 times of the aluminum salt process. Arsenic concentration of the sludge of ferric salt process is also higher greatly than that of the aluminum salt process. Therefore, the volume of the sludge produced by the ferric salt process is smaller than that of the aluminum salt process when equal amount of drinking water was treated. Accordingly, ferric salt process should be used when only high concentration arsenic existed in drinking water. On the other hand, fluoride also can be removed simultaneously while arsenic was removed by aluminum salt process. The amount of coagulant needed is the amount of coagulant required to remove fluoride separately. Fluoride can not be removed from drinking water by the ferric salt process. It was concluded that aluminum salt process should be used to remove arsenic and fluoride simultaneously from high arsenic and high fluoride coexisted drinking water.

    Organic hazardous waste often contains some salt, owing to the widespread use of alkali salts during industrial manufacturing processes. These salts cause complications during the treatment of this type of waste. Molten salt oxidation is a flameless, robust thermal process, with inherent capability of destroying the organic constituents of wastes, while retaining the inorganic ingredients in the molten salt. In the present study, molten salt oxidation is employed for treating a typical organic hazardous waste with a high content of alkali salts. The hazardous waste derives from the production of thiotriazinone. Molten salt oxidation experiments have been conducted using a lab-scale molten salt oxidation reactor, and the emissions of CO, NO, SO2, HCl and dioxins are studied. Impacts are investigated from the composition of the molten salts, the types of feeding tube, the temperature of molten carbonates and the air factor. Results show that the waste can be oxidised effectively in a molten salt bath. Temperature of molten carbonates plays the most important role. With the temperature rising from 600 °C to 750 °C, the oxidation efficiency increases from 91.1% to 98.3%. Compared with the temperature, air factor has but a minor effect, as well as the composition of the molten salts and the type of feeding tube. The molten carbonates retain chlorine with an efficiency higher than 99.9% and the emissions of dioxins are below 8 pg TEQ g-1 sample. The present study shows that molten salt oxidation is a promising alternative for the disposal of organic hazardous wastes containing a high salt content.

  11. Origin and permeability of deep ocean salts

    Hovland, M.; Rueslåtten, H.

    2009-04-01

    Large, buried salt bodies occur in numerous offshore rift-related sedimentary basins, worldwide. For most practical purposes, the conventional evaporite (solar evaporation of seawater) theory is adequate for explaining these occurrences. However, a new model for their formation has now been published (Hovland et al., 2006; 2007, 2008). This model relies on the properties of supercritical water, a fluid which does not dissolve salt (within specific temperature and pressure ranges). The model predicts that some of the large volumes of salt occurring underground in the Red Sea and also in the Mediterranean Sea, formed by forced hydrothermal circulation of seawater down to depths where it became superctical (i.e., temperatures above 405°C, and pressures above 300 bars). Thus, salt precipitated under-ground and filled up cracks and crevices and also formed massive accumulations, which partly flowed upwards as dense, hot brines, precipitating more solid salts upon cooling. In addition, Holness and Lewis (1997) have shown experimentally that salt bodies subjected to high pressures and elevated temperatures, acquire a permeability comparable to sand. This is because the crystalline structure of salt (halite) attains dihedral angles between salt crystals less than 60° at higher temperatures and pressures, allowing water to form continuous strings around all salt crystals. This allows hot dense brines to migrate through the salt. Thus, the salt may act as conduits for flow of brines and salt slurries from previously accumulated salt in the subsurface. If these brines reach the sea floor, they can also form brine-pools and layered salt bodies on the sea floor. An IODP Pre-proposal (No. 741-pre) is now actively promoting drilling some targets in order of checking out this new theory against the conventional evaporite model. It is hoped that European scientists will take up this question and actively promote drilling into salt bodies, for example in the Red Sea (The

    The aim of this paper is to design initial salt screening procedures for manufacturing ibuprofen. Salt forms of a pharmaceutical acid racemic (R,S)-(+/-)-ibuprofen and their "developable" synthetic routes were ferreted out simultaneously through the screening of seven bases of sodium hydroxide, potassium hydroxide, L-arginine, L-histidine, L-lysine, diethanolamine, and tris(hydroxymethyl)aminomethane (THAM), and the match with the use of nine organic solvents of methanol, dimethyl sulfoxide, ethanol, N, N-dimethylformamide, acetonitrile, isopropyl alcohol, 1,4-dioxane, acetone, and tetrahydrofuran mainly in the presence of water in 20 mL scintillation vials. Racemic (R,S)-(+/-)-sodium ibuprofen dihydrate, a well-known ibuprofen salt and the newly discovered racemic (R,S)-(+/-)-THAM ibuprofen, appeared as white-squared powders with a molecular weight of 327.42 g/mol, a melting point of 160.17 degrees C, and the apparent solubility product, K'(sp), of 6.0 x 10(-4) M(2) at 25 degrees C were successfully synthesized by the initial salt screening methods. The new amine salt of ibuprofen was monoclinic and had a space group of P2(1)/c and lattice parameters of a = 17.578(8) degrees, b = 10.428(4) degrees, c = 9.991(4) A, alpha = 90.00 degrees , beta = 97.17(1) degrees, gamma = 90.00 degrees, and V = 1,817.05(244) A(3). The aspect ratio of the amine salt crystals of ibuprofen of approximately 1.0 implied that the crystals had a better flowability than the sodium salt counterparts. This amine salt of ibuprofen was more stable in moist or dried atmospheres and was more hydrophobic than the sodium salt of ibuprofen. Moreover, the slow dissolution of this amine salt of ibuprofen might have made it less bitter and more suitable as a sustained release drug than the sodium salt of ibuprofen. The future work is to search for the different polymorphs of this amine salt of ibuprofen and to extend the initial salt screening working logics to the formation of co-crystals.

    2013-04-01

    Pupil talk and discussion are seen as having important social and cognitive outcomes. In science classes, pupils' collaborative talk supports the construction of meaning and helps examine the status of evidence, theory and knowledge. However, pupil interactive talk in groups is rare in science lessons. The research reported is part of a project to increase the amount of pupil-pupil talk in primary schools through a programme of teaching and professional development. Pupils' self-reports of the frequency and learning efficacies of talk related activities in science lessons were collected before and after a programme of teaching in 24 schools in one of the most socially and educationally deprived areas of England. Findings showed pupils valued talking about their ideas over listening to those of other pupils. Science talk frequency (STF) was closely correlated with science talk efficacy (STE) and both were positively correlated with pupils' attitudes to school science. Analysis of covariance (ANCOVA) of the correlation of STF with STE showed values were independent of gender and ability but that school experience was a significant factor. After the teaching programme and, contrary to expectations, the frequency of talk activities in science lessons appeared to have decreased but varied according to class grades. The degree of correlation between STF and STE was stronger after the teaching in over half of the schools. Schools where STF/STE strengthened most as a result of teaching were those involved in an additional initiative to use modelled talk related to industrial contexts.

    The mechanism by which probiotic lactobacilli affect the immune system is strain specific. As the immune system is a multicompartmental system, each strain has its way to interact with it and induce a visible and quantifiable effect. This review summarizes the interplay existing between the host immune system and probiotic lactobacilli, that is, with emphasis on lactobacilli as a prototype probiotic genus. Several aspects including the bacterial-host cross-talk with the mucosal and systemic immune system are presented, as well as short sections on the competing effect towards pathogenic bacteria and their uses as delivery vehicle for antigens. © 2014 The Society for Applied Microbiology.

    This article describes methods for analysing classroom talk, comparing their strengths and weaknesses. Both quantitative and qualitative methods are described and assessed for their strengths and weaknesses, with a discussion of the mixed use of such methods. It is acknowledged that particular methods are often embedded in particular methodologies, which are based on specific theories of social action, research paradigms, and disciplines; and so a comparison is made of two contemporary methodologies, linguistic ethnography, and sociocultural research. The article concludes with some comments on the current state of development of this field of research and on ways that it might usefully progress.

    New technique for cancellation of nonlinear cross-talk in polychromatic parametric sampling gate is described and quantified. The method relies on a newly derived look-up table method that achieves equalization and suppresses nonlinear response associated with parametric sampling operation. The new cancellation scheme is implemented in a framework of a specific parametric photonics assisted analog-to-digital conversion (ADC) copy-and-sample-all (CaSA) architecture. A 20 dB improvement in total harmonic distortion is demonstrated experimentally.

    Salt formations hold promise for eternal removal of nuclear waste from our biosphere. Germany and the United States have ample salt formations for this purpose, ranging from flat-bedded formations to geologically mature dome structures. Both nations are revisiting nuclear waste disposal options, accompanied by extensive collaboration on applied salt repository research, design, and operation. Salt formations provide isolation while geotechnical barriers reestablish impermeability after waste is placed in the geology. Between excavation and closure, physical, mechanical, thermal, chemical, and hydrological processes ensue. Salt response over a range of stress and temperature has been characterized for decades. Research practices employ refined test techniques and controls, which improve parameter assessment for features of the constitutive models. Extraordinary computational capabilities require exacting understanding of laboratory measurements and objective interpretation of modeling results. A repository for heat-generative nuclear waste provides an engineering challenge beyond common experience. Long-term evolution of the underground setting is precluded from direct observation or measurement. Therefore, analogues and modeling predictions are necessary to establish enduring safety functions. A strong case for granular salt reconsolidation and a focused research agenda support salt repository concepts that include safety-by-design. Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.

    Full Text Available During drug development, it is important to have a suitable crystalline form of the active pharmaceutical ingredient (API. Mostly, the basic options originate in the form of free base, acid, or salt. Substances that are stable only within a certain pH range are a challenge for the formulation. For the prazoles, which are known to be sensitive to degradation in an acid environment, the formulation is stabilized with alkaline additives or with the application of API formulated as basic salts. Therefore, preparation and characterization of basic salts are needed to monitor any possible salinization of free molecules. We synthesized salts of omeprazole from the group of alkali metals (Li, Na, and K and alkaline earth metals (Mg, Ca. The purpose of the presented work is to demonstrate the applicability of vibrational spectroscopy to discriminate between the OMP and OMP-salt molecules. For this reason, the physicochemical properties of 5 salts were probed using infrared and Raman spectroscopy, NMR, TG, DSC, and theoretical calculation of vibrational frequencies. We found out that vibrational spectroscopy serves as an applicable spectroscopic tool which enables an accurate, quick, and nondestructive way to determine the characteristic of OMP and its salts.

    Suppression of ion intensity in the presence of high salt matrices is common in most mass spectrometry ionization techniques. Desorption electrospray ionization (DESI) is an ionization method that exhibits salt tolerance, and this is investigated. DESI analysis was performed on three different drug mixtures in the presence of 0, 0.2, 2, 5, 10, and 20% NaCl:KCl weight by volume from seven different surfaces. At physiological concentrations individual drugs in each mixture were observed with each surface. Collision-induced dissociation (CID) was used to provide additional confirmation for select compounds. Multiple stage experiments, to MS5, were performed for select compounds. Even in the absence of added salt, the benzodiazepine containing mixture yielded sodium and potassium adducts of carbamazepine which masked the ions of interest. These adducts were eliminated by adding 0.1% 7M ammonium acetate to the standard methanol:water (1:1) spray solvent. Comparison of the salt tolerance of DESI with that of electrospray ionization (ESI) demonstrated much better signal/noise characteristics for DESI in this study. The salt tolerance of DESI was also studied by performing limit of detection and dynamic range experiments. Even at a salt concentration significantly above physiological concentrations, select surfaces were effective in providing spectra that allowed the ready identification of the compounds of interest. The already high salt tolerance of DESI can be optimized further by appropriate choices of surface and spray solution.

    Miscanthus is a woody rhizomatous C4 grass that can be used as a CO2 neutral biofuel resource. It has potential to grow in marginal areas such as saline soils, avoiding competition for arable lands with food crops. This study explored genetic diversity for salt tolerance in Miscanthus and discovered mechanisms and traits that can be used to improve the yield under salt stress. Seventy genotypes of Miscanthus (including 57 M. sinensis, 5 M. sacchariflorus, and 8 hybrids) were evaluated for salt tolerance under saline (150 mM NaCl) and normal growing conditions using a hydroponic system. Analyses of shoot growth traits and ion concentrations revealed the existence of large variation for salt tolerance in the genotypes. We identified genotypes with potential for high biomass production both under control and saline conditions that may be utilized for growth under marginal, saline conditions. Several relatively salt tolerant genotypes had clearly lower Na+ concentrations and showed relatively high K+/Na+ ratios in the shoots under salt stress, indicating that a Na+ exclusion mechanism was utilized to prevent Na+ accumulation in the leaves. Other genotypes showed limited reduction in leaf expansion and growth rate under saline conditions, which may be indicative of osmotic stress tolerance. The genotypes demonstrating potentially different salt tolerance mechanisms can serve as starting material for breeding programs aimed at improving salinity tolerance of Miscanthus. PMID:28261243

    Several fast food companies have made commitments to reduce the levels of salt in the foods they serve, but technical issues are often cited as a barrier to achieving substantial reductions. Our objective was to examine the reported salt levels for products offered by leading multinational fast food chains. Data on salt content for products served by six fast food chains operating in Australia, Canada, France, New Zealand, the United Kingdom and the United States were collected by survey in April 2010. Mean salt contents (and their ranges) were calculated and compared within and between countries and companies. We saw substantial variation in the mean salt content for different categories of products. For example, the salads we included in our survey contained 0.5 g of salt per 100 g, whereas the chicken products we included contained 1.6 g. We also saw variability between countries: chicken products from the UK contained 1.1 g of salt per 100 g, whereas chicken products from the US contained 1.8 g. Furthermore, the mean salt content of food categories varied between companies and between the same products in different countries (e.g., McDonald's Chicken McNuggets contain 0.6 g of salt per 100 g in the UK, but 1.6 g of salt per 100 g in the US). The salt content of fast foods varies substantially, not only by type of food, but by company and country in which the food is produced. Although the reasons for this variation are not clear, the marked differences in salt content of very similar products suggest that technical reasons are not a primary explanation. In the right regulatory environment, it is likely that fast food companies could substantially reduce the salt in their products, translating to large gains for population health.

  5. Salt-bridge energetics in halophilic proteins.

    Full Text Available Halophilic proteins have greater abundance of acidic over basic and very low bulky hydrophobic residues. Classical electrostatic stabilization was suggested as the key determinant for halophilic adaptation of protein. However, contribution of specific electrostatic interactions (i.e. salt-bridges to overall stability of halophilic proteins is yet to be understood. To understand this, we use Adaptive-Poison-Boltzmann-Solver Methods along with our home-built automation to workout net as well as associated component energy terms such as desolvation energy, bridge energy and background energy for 275 salt-bridges from 20 extremely halophilic proteins. We then perform extensive statistical analysis on general and energetic attributes on these salt-bridges. On average, 8 salt-bridges per 150 residues protein were observed which is almost twice than earlier report. Overall contributions of salt-bridges are -3.0 kcal mol-1. Majority (78% of salt-bridges in our dataset are stable and conserved in nature. Although, average contributions of component energy terms are equal, their individual details vary greatly from one another indicating their sensitivity to local micro-environment. Notably, 35% of salt-bridges in our database are buried and stable. Greater desolvation penalty of these buried salt-bridges are counteracted by stable network salt-bridges apart from favorable equal contributions of bridge and background terms. Recruitment of extensive network salt-bridges (46% with a net contribution of -5.0 kcal mol-1 per salt-bridge, seems to be a halophilic design wherein favorable average contribution of background term (-10 kcal mol-1 exceeds than that of bridge term (-7 kcal mol-1. Interiors of proteins from halophiles are seen to possess relatively higher abundance of charge and polar side chains than that of mesophiles which seems to be satisfied by cooperative network salt-bridges. Overall, our theoretical analyses provide insight into halophilic

    Three constitutive models are recommended as candidates for describing the deformation of crushed salt. These models are generalized to three-dimensional states of stress to include the effects of mean and deviatoric stress and modified to include effects of temperature, grain size, and moisture content. A database including hydrostatic consolidation and shear consolidation tests conducted on Waste Isolation Pilot Plant (WIPP) and southeastern New Mexico salt is used to determine material parameters for the models. To evaluate the capability of the models, parameter values obtained from fitting the complete database are used to predict the individual tests. Finite element calculations of a WIPP shaft with emplaced crushed salt demonstrate the model predictions.

    2017-01-01

    Full Text Available This study analysed children’s Theory of Mind (ToM as assessed by mental state talk in oral narratives. We hypothesized that the children’s mental state talk in narratives has an underlying structure, with specific terms organized in clusters. Ninety-eight children attending the last year of kindergarten were asked to tell a story twice, at the beginning and at the end of the school year. Mental state talk was analysed by identifying terms and expressions referring to perceptual, physiological, emotional, willingness, cognitive, moral, and sociorelational states. The cluster analysis showed that children’s mental state talk is organized in two main clusters: perceptual states and affective states. Results from the study confirm the feasibility of narratives as an outlet to inquire mental state talk and offer a more fine-grained analysis of mental state talk structure.

    Full Text Available This study attempts to integrate a gender perspective in the research of children's conceptions about learning to write. We analyzed the individual interviews of 160 schoolchildren - equally distributed between boys and girls - in the eight grades from kindergarten to seventh grade in elementary school in Argentina, in order to explore gender-related patterns in their conceptions of learning to write. The lexicometric method was applied to the transcriptions of children's responses. Subsequent qualitative analysis of modal responses revealed distinctive gender differences regarding both the content and the form of responses. We describe and interpret such differences within a theoretical framework that distinguishes two different modes of discourse and thought: the gendered conversational styles studied by Tannen, and the two modes of cognitive functioning proposed by Bruner. Results show that boys tended to adopt a report talk style and to present traits that are close to those proposed by Bruner in his portrait of the logico-paradigmatic mode of thought. Girls, instead, tended to adopt a rapport talk style and to integrate to a greater extent a set of procedures characterizing a narrative modality, by speaking at length of human actions, intentions and feelings. These findings underscore the educational potential of considering gender as an important (and still unexplored aspect that influences children's(and most probably teachers' conceptions of how one learns.

    Chan, F Y; Khalid, H M

    Usability and affective issues of using automatic speech recognition technology to interact with an automated teller machine (ATM) are investigated in two experiments. The first uncovered dialogue patterns of ATM users for the purpose of designing the user interface for a simulated speech ATM system. Applying the Wizard-of-Oz methodology, multiple mapping and word spotting techniques, the speech driven ATM accommodates bilingual users of Bahasa Melayu and English. The second experiment evaluates the usability of a hybrid speech ATM, comparing it with a simulated manual ATM. The aim is to investigate how natural and fun can talking to a speech ATM be for these first-time users. Subjects performed the withdrawal and balance enquiry tasks. The ANOVA was performed on the usability and affective data. The results showed significant differences between systems in the ability to complete the tasks as well as in transaction errors. Performance was measured on the time taken by subjects to complete the task and the number of speech recognition errors that occurred. On the basis of user emotions, it can be said that the hybrid speech system enabled pleasurable interaction. Despite the limitations of speech recognition technology, users are set to talk to the ATM when it becomes available for public use.

    2015-04-01

    Dark sectors, consisting of new, light, weakly-coupled particles that do not interact with the known strong, weak, or electromagnetic forces, are a particularly interesting possibility for new physics. Nature may contain numerous dark sectors, each with their own beautiful structure, distinct particles, and forces. Examples of dark sector particles include dark photons, axions, axion-like particles, and dark matter. In many cases, the exploration of dark sectors can proceed with existing facilities and comparatively modest experiments. This talk summarizes the physics motivation for dark sectors and the exciting opportunities for experimental exploration. Particular emphasis will be given to the search for dark photons, the mediators of a broken dark U(1) gauge theory that kinetically mixes with the Standard Model hypercharge, with masses in the MeV-to-GeV range. Experimental searches include low-energy e+e- colliders, new and old high-intensity fixed-target experiments, and high-energy colliders. The talk will highlight the APEX and HPS experiments at Jefferson Lab, which are pioneering, low-cost experiments to search for dark photons in fixed target electroproduction. Over the next few years, they have the potential for a transformative discovery.

    Words such as language and behavior are frequently used to depict "quorum sensing" (QS) in the literature. Simplifying the concept, language and cross-talk between bacteria, and between bacteria and animal or plants hosts determine the behavior (e.g., beneficial or pathogenic effects). Genomics and transcriptomics were the principal approaches used to study the multiple mechanisms of QS. Nevertheless, sequencing of genomes paved the way for another approach which consists on comparative and functional proteomics. This review aims at describing how the proteomic dictionary translates: (i) the languages (N-acyl-L-homoserine lactones, AHL; autoinducing peptide, AIP; autoinducer-2, AI-2) used by bacteria to communicate; (ii) signals of QS which induce various phenotypes (e.g., virulence, biofilm maturation); (iii) cross-talk between lactic acid bacteria within various food ecosystems (e.g. sourdough and fermented milk); (iv) probiotic messages at intra- and inter-species and interkingdom levels; and (v) words for quorum quenching (QQ). Proteomics is an indispensible discipline to elucidate the mechanisms of regulation of the multitude of language signals which diffuse through different microbial communities.

    2017-07-01

    Full Text Available Background and objectives. High salt intake increases blood pressure and thereby the risk of chronic diseases. Food reformulation (or food product improvement may lower the dietary intake of salt. This study describes the changes in salt contents of foods in the Dutch market over a five-year period (2011–2016 and differences in estimated salt intake over a 10-year period (2006–2015. Methods. To assess the salt contents of foods; we obtained recent data from chemical analyses and from food labels. Salt content of these foods in 2016 was compared to salt contents in the 2011 version Dutch Food Composition Database (NEVO, version 2011, and statistically tested with General Linear Models. To estimate the daily dietary salt intake in 2006, 2010, and 2015, men and women aged 19 to 70 years were recruited through random population sampling in Doetinchem, a small town located in a rural area in the eastern part of the Netherlands. The characteristics of the study population were in 2006: n = 317, mean age 49 years, 43% men, in 2010: n = 342, mean age 46 years, 45% men, and in 2015: n = 289, mean age 46 years, 47% men. Sodium and potassium excretion was measured in a single 24-h urine sample. All estimates were converted to a common metric: salt intake in grams per day by multiplication of sodium with a factor of 2.54. Results. In 2016 compared to 2011, the salt content in certain types of bread was on average 19 percent lower and certain types of sauce, soup, canned vegetables and legumes, and crisps had a 12 to 26 percent lower salt content. Salt content in other types of foods had not changed significantly. Between 2006, 2010 and 2015 the estimated salt intake among adults in Doetinchem remained unchanged. In 2015, the median estimated salt intake was 9.7 g per day for men and 7.4 g per day for women. As in 2006 and 2010, the estimated salt intake in 2015 exceeded the recommended maximum intake of 6 g per day set by the Dutch Health Council

    Objectives To revise an existing three-talk model for learning how to achieve shared decision making, and to consult with relevant stakeholders to update and obtain wider engagement.Design Multistage consultation process.Setting Key informant group, communities of interest, and survey of clinical specialties.Participants 19 key informants, 153 member responses from multiple communities of interest, and 316 responses to an online survey from medically qualified clinicians from six specialties.Results After extended consultation over three iterations, we revised the three-talk model by making changes to one talk category, adding the need to elicit patient goals, providing a clear set of tasks for each talk category, and adding suggested scripts to illustrate each step. A new three-talk model of shared decision making is proposed, based on "team talk," "option talk," and "decision talk," to depict a process of collaboration and deliberation. Team talk places emphasis on the need to provide support to patients when they are made aware of choices, and to elicit their goals as a means of guiding decision making processes. Option talk refers to the task of comparing alternatives, using risk communication principles. Decision talk refers to the task of arriving at decisions that reflect the informed preferences of patients, guided by the experience and expertise of health professionals.Conclusions The revised three-talk model of shared decision making depicts conversational steps, initiated by providing support when introducing options, followed by strategies to compare and discuss trade-offs, before deliberation based on informed preferences.

    1987-09-01

    Elemental study and concentration determinations have been conducted on Jordanian crude salt using Rutherford Back-Scattering (RBS) and X-ray Fluorescence (SRF) spectrometry techniques. Analysis have also been carried out on different purified salt samples available in the local market. The concentration of some elements, in particular bromide, content and its significance on human health and nutrition is discussed. Results reveal relatively high traces of elemental concentrations in crude salt. For example, bromide concentration ranges from 178 to 384 ppm in comparison to a tolerance limit of 30 ppm set by the Unites States Food and Drug Administration (USDA) and other International Agencies like FAO/WHO. It is suggested that refining crude salt may result in a reduction of bromide concentration and other traces considerably, thus making it feasible for human consumption.

    Full Text Available Baia Verde – Slanic Prahova Lakes Complex have been formed by water accumulation resulted out of infiltrated salted water from bell shaped surface salt mines dated XVII century (1685. Such lakes, as per their method of formation, can be also found in other places from the SubCarpathians area (Telega – Prahova, Ocnele Mari – Valcea, Transilvanian Depression (Ocna Sibiului, Turda, Sovata, Ocna Dejului, etc.. Water contact with diapires, in the places where have always existed such mining explorations and exploitation, has determined the formation of salted lakes having balneary and therapeutically qualities and sometimes the development of a heliothermic / mezothermic bed. At Slanic – Prahova besides the three lakes known as Baia Verde 1, 2 and 3, there is also the lake Baia Baciului situated at the border of “Salt Mountain” which represented the first objective for capitalization of the balnear and therapeutically potential of the area.

    Post-translational modification (PTM)1 plays an important role in regulating the functions of proteins. PTMs of multiple residues on one protein may work together to determine a functional outcome, which is known as PTM cross-talk. Identification of PTM cross-talks is an emerging theme in proteomics and has elicited great interest, but their properties remain to be systematically characterized. To this end, we collected 193 PTM cross-talk pairs in 77 human proteins from the literature and then tested location preference and co-evolution at the residue and modification levels. We found that cross-talk events preferentially occurred among nearby PTM sites, especially in disordered protein regions, and cross-talk pairs tended to co-evolve. Given the properties of PTM cross-talk pairs, a naïve Bayes classifier integrating different features was built to predict cross-talks for pairwise combination of PTM sites. By using a 10-fold cross-validation, the integrated prediction model showed an area under the receiver operating characteristic (ROC) curve of 0.833, superior to using any individual feature alone. The prediction performance was also demonstrated to be robust to the biases in the collected PTM cross-talk pairs. The integrated approach has the potential for large-scale prioritization of PTM cross-talk candidates for functional validation and was implemented as a web server available at http://bioinfo.bjmu.edu.cn/ptm-x/.

    Communication errors can reduce patient safety, especially in emergency situations that require rapid responses by experts in a number of medical specialties. Talking to each other is crucial for utilizing the collective expertise of the team. Here we explored the functions of "team talk" (talking between team members) with an emphasis on the talk-work relationship in interdisciplinary emergency teams. Five interdisciplinary medical emergency teams were observed and videotaped during in situ simulations at an emergency department at a university hospital in Norway. Team talk and simultaneous actions were transcribed and analysed. We used qualitative discourse analysis to perform structural mapping of the team talk and to analyse the function of online commentaries (real-time observations and assessments of observations based on relevant cues in the clinical situation). Structural mapping revealed recurring and diverse patterns. Team expansion stood out as a critical phase in the teamwork. Online commentaries that occurred during the critical phase served several functions and demonstrated the inextricable interconnections between team talk and actions. Discourse analysis allowed us to capture the dynamics and complexity of team talk during a simulated emergency situation. Even though the team talk did not follow a predefined structure, the team members managed to manoeuvre safely within the complex situation. Our results support that online commentaries contributes to shared team situation awareness. Discourse analysis reveals naturally occurring communication strategies that trigger actions relevant for safe practice and thus provides supplemental insights into what comprises "good" team communication in medical emergencies.

    The discussion that occurs between a pediatric oncologist and a family when they first learn about their child's new diagnosis of cancer is known as the "Day One Talk." Few studies have addressed parent preferences when learning that their child has been diagnosed with cancer. The objective of this study is to assess what information parents of children with newly diagnosed cancer believe is important to learn during the Day One Talk. In this cross-sectional study, a survey tool based on expert opinion was created to assess parents' views of components of the Day One Talk including its content, length, and setting, as well as whether the child should be present for the initial talk and which staff should be present for the talk. Sixty-two parents of children with newly diagnosed cancer participated. Ninety-seven percent believed that the Day One Talk is extremely important. Ninety percent believed that the word "cancer" should be used during the Day One Talk. Seventy-seven percent believed that the pediatric oncologist should provide specific numbers regarding cure rates for the patient's diagnosis. Eighty-four percent of parents do not believe that children younger than 14 should be present. These results suggest that parents of children with cancer have certain preferences regarding the Day One Talk. When conducting the Day One Talk, providers should elicit parent preferences regarding these issues in order to best meet families' needs.

    DNA methylation has been referred as an important player in plant genomic responses to environmental stresses but correlations between the methylome plasticity and specific traits of interest are still far from being understood. In this study, we inspected global DNA methylation levels in salt tolerant and sensitive rice varieties upon salt stress imposition. Global DNA methylation was quantified using the 5-methylcytosine (5mC) antibody and an ELISA-based technique, which is an affordable and quite pioneer assay in plants, and in situ imaging of methylation sites in interphase nuclei of tissue sections. Variations of global DNA methylation levels in response to salt stress were tissue- and genotype-dependent. We show a connection between a higher ability of DNA methylation adjustment levels and salt stress tolerance. The salt-tolerant rice variety Pokkali was remarkable in its ability to quickly relax DNA methylation in response to salt stress. In spite of the same tendency for reduction of global methylation under salinity, in the salt-sensitive rice variety IR29 such reduction was not statistically supported. In ‘Pokkali’, the salt stress-induced demethylation may be linked to active demethylation due to increased expression of DNA demethylases under salt stress. In ‘IR29’, the induction of both DNA demethylases and methyltransferases may explain the lower plasticity of DNA methylation. We further show that mutations for epigenetic regulators affected specific phenotypic parameters related to salinity tolerance, such as the root length and biomass. This work emphasizes the role of differential methylome flexibility between salt tolerant and salt sensitive rice varieties as an important player in salt stress tolerance, reinforcing the need to better understand the connection between epigenetic networks and plant responses to environmental stresses.

    Despite the ecological and economic importance of Great Salt Lake, only limited water quality monitoring has occurred historically. To change this, new monitoring stations and networks—gauges of lake level height and rate of inflow, moored buoys, and multiple lake-bottom sensors—will provide important information that can be used to make informed decisions regarding future management of the Great Salt Lake ecosystem.

    A purification method that uses ion-selective ceramics to electrochemically filter waste products from a molten salt. The electrochemical method uses ion-conducting ceramics that are selective for the molten salt cations desired in the final purified melt, and selective against any contaminant ions. The method can be integrated into a slightly modified version of the electrochemical framework currently used in pyroprocessing of nuclear wastes.

    2014-11-01

    The need for speech-language pathologists (SLPs) to consider an academic talk (AT) register in addition to an everyday casual talk (CT) register of oral language with children beginning in the preschool years is presented, the AT and CT registers are distinguished in a comprehensive manner, ideas regarding AT language assessment are proposed, and suggestions for fostering children's skills with the AT register are offered. Extant research and scholarship from a wide variety of disciplines are integrated and organized. The author discusses the role of the SLP in supporting AT skills beginning in the preschool years and the added risk of difficulties with the AT register for children with language impairment who are from diverse backgrounds. Two broad categories-social-interactive and cognitive-that give rise to linguistic features that differentiate between the CT and AT registers are deduced from extant scholarship. SLPs should consider children's competence with the AT register as they work to prepare preschoolers and older children for the language demands of school.

  14. Talking about science: An interpretation of the effects of teacher talk in a high school science classroom

    Science.gov (United States)

    Moje, Elizabeth B.

    This paper builds on research in science education, secondary education, and sociolinguistics by arguing that high school classrooms can be considered speech communities in which language may be selectively used and imposed on students as a means of fostering academic speech community identification. To demonstrate the ways in which a high school teacher's language use may encourage subject area identification, the results of an interactionist analysis of data from a 2-year ethnographic study of one high school chemistry classroom are presented. Findings indicate that this teacher's uses of language fell into three related categories. These uses of language served to foster identification with the academic speech community of science. As a result of the teacher's talk about science according to these three patterns, students developed or reinforced particular views of science. In addition, talking about science in ways that fostered identity with the discipline promoted the teacher as expert and built classroom solidarity or community. These results are discussed in light of sociolinguistic research on classroom competence and of the assertions of science educators regarding social and ideologic implications of language use in science instruction.Received: 23 September 1993; Revised: 15 September 1994;

    The water and salt balance of Great Salt Lake primarily depends on the amount of inflow from tributary streams and the conveyance properties of a causeway constructed during 1957-59 that divides the lake into the south and north parts. The conveyance properties of the causeway originally included two culverts, each 15 feet wide, and the permeable rock-fill material.During 1980-86, the salt balance changed as a result of record high inflow that averaged 4,627,000 acre-feet annually and modifications made to the conveyance properties of the causeway that included opening a 300-foot-wide breach. In this study, a model developed in 1973 by Waddell and Bolke to simulate the water and salt balance of the lake was revised to accommodate the high water-surface altitude and modifications made to the causeway. This study, done by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of State Lands and Forestry, updates the model with monitoring data collected during 1980-86. This report describes the calibration of the model and presents the results of simulations for three hypothetical 10-year periods.During January 1, 1980, to July 31, 1984, a net load of 0.5 billion tons of dissolved salt flowed from the south to the north part of the lake primarily as a result of record inflows. From August 1, 1984, when the breach was opened, to December 31,1986, a net load of 0.3 billion tons of dissolved salt flowed from the north to the south part of the lake primarily as a result of the breach.For simulated inflow rates during a hypothetical 10-year period resulting in the water-surface altitude decreasing from about 4,200 to 4,192 feet, there was a net movement of about 1.0 billion tons of dissolved salt from the south to the north part, and about 1.7 billion tons of salt precipitated in the north part. For simulated inflow rates during a hypothetical 10-year period resulting in a rise in water-surface altitude from about 4,200 to 4

    The uptake, depuration and toxicity of environmental nitrite was characterized in Litopenaeus vannamei exposed in water containing low concentrations of artificial sea salt or mixed salts. In 2 g/L artificial sea salts, nitrite was concentrated in the hemolymph in a dose-dependent and rapid manner (steady-state in about 2 d). When exposed to nitrite in 2 g/L artificial sea salts for 4 d and then moved to a similar environment without added nitrite, complete depuration occurred within a day. Increasing salinity up to 10 g/L decreased uptake of environmental nitrite. Nitrite uptake in environments containing 2 g/L mixed salts (combination of sodium, potassium, calcium and magnesium chlorides) was similar to or lower than rates in 2 g/L artificial sea salt. Toxicity was inversely related to total dissolved salt and chloride concentrations and was highest in 2 g/L artificial sea salt (96-h medial lethal concentration = 8.4 mg/L nitrite-N). Animals that molted during the experiments did not appear to be more susceptible to nitrite than animals that did not molt. The shallow slope of the curve describing the relationship between toxicity and salinity suggests that management of nitrite toxicity in low-salinity shrimp ponds by addition of more salts may not be practical. ??

    Molten salt technology is a catchall phrase that includes some very diverse technologies; electrochemistry, heat transfer, chemical oxidation/reduction baths, and nuclear reactors. All of these technologies are linked by the general characteristics of molten salts that can function as solvents, have good heat-transfer characteristics, function like a fluid, can attain very high temperatures, can conduct electricity, and also may have chemical catalytic properties. The Janz molten salt database is the most comprehensive compilation of property data about molten salts available today and is widely used for both fundamental and applied purposes. Databases are traditionally viewed as “static” documents that are used in a “search and retrieval” mode. These static data can be transformed by informatics and data mining tools into a dynamic dataset for analysis of the properties of the, materials and for making predictions. While this approch has been successful in the chemical and biochemical sciences in searching for and establishing structure-property relationships, it is not widely used in the materials science community. Because the design of the original molten salt database was not oriented toward this informatics goal, it was essential to evaluate this dataset in terms of data mining standards. Two techniques were used—a projection (principal components analysis (PCA)) and a predictive method (partial least squares (PLS))—in conjunction with fundamental knowledge acquired from the long-term practice of molten salt chemistry.

    The phase stability of molten salts in an electrorefiner (ER) may be adversely affected by the buildup of sodium, fission products, and transuranics in the electrolyte. Potential situations that need to be avoided are the following: (1) salt freezing due to an unexpected change in the liquidus temperature, (2) phase separation or non-homogeneity of the molten salt due to the precipitation of solids or formation of immiscible liquids, and (3) any mechanism that can result in the separation and concentration of fissile elements from the molten salt. Any of these situations would result in an off-normal condition outside the established safety basis for electrorefiner (ER) operations. The stability (and homogeneity) of the phases can potentially be monitored through the thermal characterization of the salts, which can be a function of impurity concentration. This report describes the experimental results of typical salts compositions, which consist of chlorides of potassium, lithium, strontium, samarium, praseodymium, lanthanum, barium, cerium, cesium, neodymium, sodium and gadolinium chlorides as a surrogate for both uranium and plutonium, used for the processing of used nuclear fuels.

    2015-01-01

    Despite the many HIV/AIDS communication initiatives, combined with support and infrastructural support in South Africa, risky behaviour associated with the spread of the epidemic is increasing amongst many groups. This calls for a re-evaluation of endeavours aimed at curbing the spread of the epidemic. This article is only concerned with the communicational aspects of the epidemic, but does not negate the interaction of these with other measures taken to address the epidemic. As is the case with most health communication initiatives, HIV/AIDS communication initiatives have evolved to favour the participatory approach above one-directional transmission of information to the public. The participatory approach rests on the assumption that an HIV/AIDS communication initiative stands the best chance of resulting in behaviour change if members of the target community participate in the communication initiative. The assumption is that as many people as possible should be involved in the maximum number of phases of the communicative initiative (such as initial research, planning, implementation and evaluation of the project). Some research has recently started to explore new forms of community participation, including inviting community participation through, for example, internet-based platforms such as social media, and mobile phone platforms such as WhatsApp and BBM. However, the reality broadcast genre--more specifically, talk radio--has been neglected, as only a few research investigations focused on talk radio and most of these are not exclusively about HIV/AIDS communication but focus on other health topics. From a participatory communication perspective, two sets of critique against the existing HIV/AIDS communication projects hold water: firstly, they do not make the maximum use of participatory communication principles and, secondly, they are externally initiated projects and emanate from outside the target community. To address both of these concerns, this

    One of the common characteristics of planets Earth and Mars is that both host water (H2O) and large accumulations of salt. Whereas Earth’s surface-environment can be regarded as ‘water-friendly’ and ‘salt hostile’, the reverse can be said for the surface of Mars. This is because liquid water is stable on Earth, and the atmosphere transports humidity around the globe, whereas on planet Mars, liquid water is unstable, rendering the atmosphere dry and, therefore, ‘salt-friendly’. The riddle as to how the salt accumulated in various locations on those two planets, is one of long-lasting and great debate. The salt accumulations on Earth are traditionally termed ‘evaporites’, meaning that they formed as a consequence of the evaporation of large masses of seawater. How the accumulations on Mars formed is much harder to explain, as an ocean only existed briefly. Although water molecules and OH-groups may exist in abundance in bound form (crystal water, adsorbed water, etc.), the only place where free water is expected to be stable on Mars is within underground faults, fractures, and crevices. Here it likely occurs as brine or in the form of ice. Based on these conditions, a key to understanding the accumulation of large deposits of salt on both planets is linked to how brines behave in the subsurface when pressurized and heated beyond their supercritical point. At depths greater than about 3 km (P>300 bars) water will no longer boil in a steam phase. Rather, it becomes supercritical and will attain the phase of supercritical water vapor (SCRIW) with a specific gravity of typically 0.3 g/cm3. An important characteristic of SCRIW is its inability to dissolve the common sea salts. The salt dissolved in the brines will therefore precipitate as solid particles when brines (seawater on the Earth) move into the supercritical P&T-domain (T>400°C, P>300 bars). Numerical modeling of a hydrothermal system in the Atlantis II Deep of the Red Sea indicates that a

    "Fat talk" is the conversational phenomenon whereby people berate their bodies in social circles. This study assessed whether norms of fat talk differ for overweight versus average-weight women. Sixty-three women read a script depicting a fat talk situation during which an overweight or average-weight target woman engaged in positive or negative body talk. Regardless of the target's weight, participants perceived it to be more typical and less surprising if she engaged in negative body talk (fat talk) rather than positive body talk. Furthermore, fat talk from either weight group did not affect the likeability of the target, but women, overweight or of average weight, who engaged in positive talk were perceived to have more socially desirable personality characteristics.

    Provided are electrochemical cells and electrolytes used to build such cells. An electrolyte includes at least one salt having a molecular weight less than about 250. Such salts allow forming electrolytes with higher salt concentrations and ensure high conductivity and ion transport in these electrolytes. The low molecular weight salt may have a concentration of at least about 0.5M and may be combined with one or more other salts, such as linear and cyclic imide salts and/or methide salts. The concentration of these additional salts may be less than that of the low molecular weight salt, in some embodiments, twice less. The additional salts may have a molecular weight greater than about 250. The electrolyte may also include one or more fluorinated solvents and may be capable of maintaining single phase solutions at between about -30.degree. C. to about 80.degree. C.

  8. Brines formed by multi-salt deliquescence

    2005-11-04

    The FY05 Waste Package Environment testing program at Lawrence Livermore National Laboratory focused on determining the temperature, relative humidity, and solution compositions of brines formed due to the deliquescence of NaCl-KNO{sub 3}-NaNO{sub 3} and NaCl-KNO{sub 3}-NaNO{sub 3}-Ca(NO{sub 3}){sub 2} salt mixtures. Understanding the physical and chemical behavior of these brines is important because they define conditions under which brines may react with waste canister surfaces. Boiling point experiments show that NaCl-KNO{sub 3}-NaNO{sub 3} and NaCl-KNO{sub 3}-NaNO{sub 3}-Ca(NO{sub 3}){sub 2} salt mixtures form brines that transform to hydrous melts that do not truly 'dry out' until temperatures exceed 300 and 400 C, respectively. Thus a conducting solution is present for these salt assemblages over the thermal history of the repository. The corresponding brines form at lower relative humidity at higher temperatures. The NaCl-KNO{sub 3}-NaNO{sub 3} salt mixture has a mutual deliquescence relative humidity (MDRH) of 25.9% at 120 C and 10.8% at 180 C. Similarly, the KNO{sub 3}-NaNO{sub 3} salt mixture has MDRH of 26.4% at 120 C and 20.0% at 150 C. The KNO{sub 3}-NaNO{sub 3} salt mixture salts also absorb some water (but do not appear to deliquesce) at 180 C and thus may also contribute to the transfer of electrons at interface between dust and the waste package surface. There is no experimental evidence to suggest that these brines will degas and form less deliquescent salt assemblages. Ammonium present in atmospheric and tunnel dust (as the chloride, nitrate, or sulfate) will readily decompose in the initial heating phase of the repository, and will affect subsequent behavior of the remaining salt mixture only through the removal of a stoichiometric equivalent of one or more anions. Although K-Na-NO{sub 3}-Cl brines form at high temperature and low relative humidity, these brines are dominated by nitrate, which is known to inhibit corrosion at lower

    Full Text Available In this paper I discuss changing work practices in post-bureaucratic organisations (Heckscher and Donellon 1994, Iedema 2003 as a move from a focus on how those in control formulate what is to happen at the level of work, towards requiring workers to verbalise how they see themselves as being able to contribute to the organisation. Workers are increasingly asked to talk about their work, and to negotiate their understandings of their work with others in the workplace – they are becoming discourse workers. This discourse work is integral to the increasing textualisation of work. These work practices are imbued with tensions as workers try to make sense of, and learn, new ways of ‘being’ a worker, and an important site of this struggle and learning is working in teams.

  11. Mothers talk about their children with schizophrenia: a performance autoethnography.

    Science.gov (United States)

    Schneider, B

    2005-06-01

    This article presents the script for a performance autoethnography that explores how mothers of adults with schizophrenia talk about their children. The script draws on my own experience as a mother of a person with schizophrenia, interviews I conducted with mothers of people with schizophrenia, and written accounts by mothers of people with schizophrenia. Autoethnography refers to an approach to social science research in which the experience of the researcher is recognized as a salient part of the research process. Autoethnography typically uses non-traditional genres, such as this script, for presenting research to address ethical and political problems in the representation of research. These genres allow researchers to both break with and continue the ethnographic tradition of representing the lives and experiences of others.

    Walton, Chris; Coyle, Adrian; Lyons, Evanthia

    2004-09-01

    This study is concerned with men's talk about emotions and with how emotion discourses function in the construction and negotiation of masculine ways of doing emotions and of consonant masculine subject positions. A sample group of 16 men, who were recruited from two social contexts in England, participated in focus groups on 'men and emotions'. Group discussions were transcribed and analysed using discourse analysis. Participants drew upon a range of discursive resources in constructing masculine emotional behaviour and negotiating masculine subject positions. They constructed men as emotional beings, but only within specific, rule-governed contexts, and cited death, a football match and a nightclub scenario as prototypical contexts for the permissible/understandable expression of grief, joy and anger, respectively. However, in the nightclub scenario, the men distanced themselves from the expression of anger as violence, whilst maintaining a masculine subject position. These discursive practices are discussed in terms of the possibilities for effecting change in men's emotional lives.

    Many researchers within the social sciences, medicine, and humanities have examined the ways people talk and think about depression. In their research and published literature they have attempted to determine the theoretical frameworks and appropriate language for categorizing such concepts and understandings. Drawing from mental health and broader social science scholarship, in this article we examine three approaches to developing an inclusive understanding of depression experiences: explanatory models, exploratory maps, and illness narratives. Utilizing these terms in the analysis of a single dataset, we identified multiple conceptual terms with potential analytical validity. Furthermore, we argue that variable usage and meanings of these concepts among lay people might contribute to a shared understanding of depression between lay people and experts, and ultimately have positive consequences for clinical practice.

    Full Text Available The present study aims to investigate the use of discourse markers (DMs in non-native (Croatian EFL teachers´ talk with primary and secondary school students. The study concentrates on the occurrences and frequencies of DMs, but it also provides an account of the function distribution of the three most frequently used DMs (ok, so, and. The quantitative and qualitative analyses of the recorded transcriptions reveal that the teachers use a variety of DMs, almost exclusively the ones typical of classroom management and classroom discourse organization, with no significant differences in the patterns of DM use with the primary and secondary school students. The DMs fulfill a number of structural and interpersonal functions mainly aimed at providing coherent and stimulating classroom discourse. The findings of this study might contribute to raising awareness of the diversified functions of DMs, which could facilitate non-native EFL teachers´ overall lesson organization and structuring of particular teaching segments.

  18. Ethylene and Hormonal Cross Talk in Vegetative Growth and Development.

    Science.gov (United States)

    Van de Poel, Bram; Smet, Dajo; Van Der Straeten, Dominique

    2015-09-01

    Ethylene is a gaseous plant hormone that most likely became a functional hormone during the evolution of charophyte green algae, prior to land colonization. From this ancient origin, ethylene evolved into an important growth regulator that is essential for myriad plant developmental processes. In vegetative growth, ethylene appears to have a dual role, stimulating and inhibiting growth, depending on the species, tissue, and cell type, developmental stage, hormonal status, and environmental conditions. Moreover, ethylene signaling and response are part of an intricate network in cross talk with internal and external cues. Besides being a crucial factor in the growth control of roots and shoots, ethylene can promote flowering, fruit ripening and abscission, as well as leaf and petal senescence and abscission and, hence, plays a role in virtually every phase of plant life. Last but not least, together with jasmonates, salicylate, and abscisic acid, ethylene is important in steering stress responses. © 2015 American Society of Plant Biologists. All Rights Reserved.

    Herijgers, Mlc Marloes; Maat, Hlw Henk Pander

    2017-06-01

    Although institutional discourse is subject to a vast ensemble of constraints, its design is not fixed beforehand. On the contrary, optimizing the satisfaction of these constraints requires considerable discourse design skills from institutional agents. In this article, we analyze how Dutch banks' mortgage advisors navigate their way through the consultations context. We focus on what we call discourse design explications, that is, stretches of talk in which participants refer to conflicting constraints in the discourse context, at the same time proposing particular discourse designs for dealing with these conflicts. We start by discussing three forms of design explication. Then we will examine the various resolutions they propose for constraint conflicts and show how advisors seek customer consent or cooperation for the proposed designs. Thus our analysis reveals how institutional agents, while providing services, work on demonstrating how the design of these services is optimized and tailored to customers.

    Full Text Available RFID is a key which enables technology for the Internet of Things paradigm, allowing the virtualization of the physical objects into the Internet. There are uncountable applications whereby these connected objects can be a breakthrough for new business models, and this work shows a good example of that. We present the RFID Presenter as the evolution of a classical consumer electronic product to a novel connected Internet product with the addition of the RFID technology. It supposes a new way to manage the conference talks in a personalization way, improving the end-user interaction and providing services that were impossible before. The design, implementation, and validation of a real gadget are well explained in order to give a real example of how the Internet of Things can be integrated into daily objects and enhance the end-user experiences.

  1. What is the right way to talk about extreme events?

    Science.gov (United States)

    Sobel, A. H.

    2013-12-01

    Extreme weather events draw the attention of the public. By demonstrating the vulnerability of human society to climate, extreme events can cause nonscientists -government leaders as well as the broader population - to take the danger posed by anthropogenic global warming more seriously than they otherwise might. An extreme event that draws media attention can become a 'teachable moment'. But extreme events are difficult to talk about in a way that honors both the strengths and weaknesses of the underlying science. No single event can be attributed to climate change, and some types of events are not even clearly influenced by it (or not in any ways our science can yet demonstrate). Strong, media-friendly statements that closely connect specific events to climate - designed to make best use of the moment's teachability - can easily overstate the case. This will raise the hackles of one's colleagues, at a minimum, and at worst, may damage the credibility of the field more broadly. Yet talking too much about the uncertainties runs the risk of understating the basic truth that global warming is real and dangerous, and may lend inadvertent support to anti-scientific denialism. I will discuss this tension in the context of my own experiences in the media after 'Superstorm' Sandy. I will address arguments I have heard, from social scientists and media consultants, to the effect that climate scientists should adopt communications strategies that lead to stronger, more media-friendly statements, and learn to suppress the tendency, bred into us during our scientific training, to emphasize the uncertainties.

  3. Salt Sensitivity Determined From Capillary Blood

    Directory of Open Access Journals (Sweden)

    Hans Oberleithner

    2016-06-01

    Full Text Available Background/Aims: A significant rise of blood pressure in response to a given salt load is a weak indication of high salt sensitivity, supposed to foster the development of arterial hypertension and related diseases in later life. In search of an alternative method we recently developed the salt blood test (SBT, a new concept for quantifying salt sensitivity (SS. Based on this concept, namely that red blood cells (RBC report on salt sensitivity, the SBT-mini was developed. Methods: The SBT-mini utilizes a droplet of capillary blood mixed with a ‘smart' Na+ cocktail. Red blood cells (RBC of this mixture are allowed to sediment by gravity in a glass tube. SS is quantified by measuring RBC sedimentation rate. 90 healthy volunteers (39 males, 51 females; mean age: 23±0.5 years were evaluated and ‘standard values' for males and females were derived. Results: Sodium buffer capacity of female blood is about 20 % smaller as compared to male blood due to the lower hematocrit of females. SS of an individual is related to the mean standard value (set to 100 % of the respective male/female cohort. High SS (> 120 % has been found in 31 % of males and 28 % of females. Conclusions: SS can be estimated derived from the individual RBC sodium buffer capacity as measured by the SBT-mini. About one third of a healthy test cohort exhibits a high sensitivity to salt. Reduction of sodium consumption to at least two grams per day (equals five grams of NaCl per day as suggested by the WHO is recommended, particularly for individuals with high salt sensitivity.

    Mohamed, Ahmed A; Salmi, Zakaria; Dahoumane, Si Amar; Mekki, Ahmed; Carbonnier, Benjamin; Chehimi, Mohamed M

    This paper reviews the surface modification strategies of a wide range of nanomaterials using aryldiazonium salts. After a brief history of diazonium salts since their discovery by Peter Griess in 1858, we will tackle the surface chemistry using these compounds since the first trials in the 1950s. We will then focus on the modern surface chemistry of aryldiazonium salts for the modification of materials, particularly metallic, semiconductors, metal oxide nanoparticles, carbon-based nanostructures, diamond and clays. The successful modification of sp(2) carbon materials and metals by aryldiazonium salts paved the way to innovative strategies for the attachment of aryl layers to metal oxide nanoparticles and nanodiamonds, and intercalation of clays. Interestingly, diazotized surfaces can easily trap nanoparticles and nanotubes while diazotized nanoparticles can be (electro)chemically reduced on electrode/materials surfaces as molecular compounds. Both strategies provided organized 2D surface assembled nanoparticles. In this review, aryldiazonium salts are highlighted as efficient coupling agents for many types of molecular, macromolecular and nanoparticulate species, therefore ensuring stability to colloids on the one hand, and the construction of composite materials and hybrid systems with robust and durable interfaces/interphases, on the other hand. The last section is dedicated to a selection of patents and industrial products based on aryldiazonium-modified nanomaterials. After nearly 160 years of organic chemistry, diazonium salts have entered a new, long and thriving era for the benefit of materials, colloids, and surface scientists. This tempts us to introduce the terminology of "diazonics" we define as the science and technology of aryldiazonium salt-derived materials. Copyright © 2015 Elsevier B.V. All rights reserved.

  5. Effects of smell loss (hyposmia) on salt usage.

    Science.gov (United States)

    Henkin, Robert I

    2014-06-01

    Smell loss (hyposmia) inhibits flavor perception and influences food intake. To compensate for flavor loss, some patients with hyposmia appear to increase salt usage. The purpose of this study was to compare self-reported salt usage in patients with hyposmia with that in normal volunteers. Salt usage was compared in 56 patients with hyposmia but with normal taste function with that in 27 normal volunteers. Salt usage was formulated with respect to 1) a standard quantitative salt intake scale, 2) salt addition related to food intake, 3) intake of foods and beverages with high salt content, and 4) salt intake related to presence or absence of hypertension. Eighteen (32%) of the 56 patients self-reported increased salt usage; they were labeled "increased users." The other 38 hyposmic patients (68%) did not report increased salt usage; they were labeled "non-changers." Increased users estimated their salt usage rose an average 2.8 times that experienced before their hyposmia onset. They also reported adding salt to their food before tasting it and ate more highly salted foods than did the non-changers. Salt usage was not increased further among increased users with hypertension but was increased further among non-changers with hypertension. Salt usage is increased among some patients with hyposmia presumably to enhance flavor perception to compensate for diminished flavor perception related to loss of smell.

    In this study, we wished to determine the relationship between the Talk Test physiological and perceptual indicators and variables measured at the ventilatory and lactate thresholds, and if the Talk Test indicators were associated with a typical exercise prescription. Fifteen participants (13 males and 2 females; age 18-35 years) underwent a treadmill lactate threshold test followed by a VO2max (maximal oxygen consumption) test in which the ventilatory threshold was determined. On a separate day, a Talk Test was administered in which participants read a passage during exercise and rated speaking comfort: "comfortable" (+Talk Test), "not sure" (+/-Talk Test), or "not able to speak comfortably" (-Talk Test). Exercise prescriptions based on 65% and 80% of heart rate reserve and VO2 reserve were determined. Lactate threshold values were significantly higher than those at the ventilatory threshold (P ACSM exercise intensity guidelines. Therefore, the Talk Test can be used in this population to prescribe exercise, and Talk Test data are more strongly related to physiological and perceptual variables corresponding to the lactate threshold than to the ventilatory threshold.

    Science.gov (United States)

    May, Natalie; Plews-Ogan, Margaret

    2012-09-01

    The aim was to examine the role of talking (or remaining silent) in the physician's experience of coping with medical error. Sixty-one physicians participated in in-depth interviews about their experience of coping with a serious medical error. We analyzed verbatim transcripts to develop a taxonomic analysis of talking domains to capture the physician experience of talking and coping with error. Talking (or not talking) about a medical error was an important aspect of the physicians' experience. After an error, honest conversations with patients and families, the medical team, colleagues, mentors, and others were critical early steps toward healing. Talking with others was important for processing and finding meaning. Many physicians used their stories to teach and help others. Some types of conversation were unhelpful, such as those that were cruel, insensitive, self-serving, and dishonest. Talking with well-intentioned colleagues and family members was often unhelpful if they minimized the error. Physicians' opportunities to talk about their experience in a meaningful way is associated with their ability to recover after a serious medical error. This work may inform institutional policies, practices, and training to help physicians effectively prepare for and cope with medical error. Copyright © 2012 Elsevier Ireland Ltd.

  6. Light-hearted death talk in a palliative day care context.

    Science.gov (United States)

    Langley-Evans, A; Payne, S

    1997-12-01

    This paper reports on an ethnographic investigation of a palliative day care unit. The aim of the study was to explore communication processes amongst patients with terminal disease, in an 'open awareness' context. The research involved participant observation over a period of 7 weeks. Detailed field notes were written and documentary information gathered on site. Analysis of the data showed that in the day care environment, patients readily talked about cancer, illness and death. Five themes were identified in the content of such 'death talk': talk about illness, symptoms and treatment, stories about illness and death, talk about patient deaths, talk regarding bereavement, and talk concerning personal mortality. In addition to content, it is maintained that the form of the patients' talk is pertinent to an understanding of the discursive context of palliative day care. It is proposed that the light-hearted and humorous nature of patient 'death talk' serves an important psychological function in allowing patients to distance themselves from their own deaths whilst simultaneously permitting an acknowledgement of their terminal condition. This suggests that the provision of an appropriate 'social' environment for patients with terminal disease may be as important to patients as one-to-one counselling by clinical nurse specialists.

    The present study investigated how eating pathology and depressive symptoms were related to the dyadic dynamics of fat talk in mother-daughter relationships during adolescence. The current sample included 100 mother-daughter dyads who completed a survey on their fat talk disclosure, eating pathology, and depressive symptoms. The Actor-Partner Interdependence Model (APIM) was utilized for the dyadic data. Adolescent girls' and mothers' engagement in fat talk was related to their own eating pathology. Daughters, but not mothers, who engaged in more fat talk reported more depressive symptoms. When mothers and daughters both had high levels of fat talk, it was associated with a higher risk of daughters' eating pathology. Adolescent girls who engaged in fat talk reported higher depressive symptoms when their mothers did not reciprocate with more fat talk. This study highlights the importance of an interpersonal approach to fat talk research and clinical interventions addressing adolescents' eating disorders and depression.

  19. How Do Intimate Partner Violent Men Talk About Self-Control?

    This study investigates discourses that male perpetrators of intimate partner violence (IPV) use regarding self-control when talking about their IPV. Literature addressing the role of self-control in committing and avoiding using violence toward partners is discussed; however, it is shown that self-control has not been investigated from a discursive psychological perspective, in which the function of talk, rather than what this talk says about speakers' cognitions, is analyzed. Discourse analysis of interviews with six male perpetrators, currently attending treatment and selected for their recent and multiple uses of IPV, revealed that talk of lacking self-control was used to account for situations when individuals engaged in violence. Conversely, talk about having self-control was used to account for refraining from IPV. An improvement narrative in which perpetrators of violence talked about moving from lacking to gaining self-control was also evident. Talk about self-control however was not as simple as this suggests because of particular note is the situation where perpetrators offered varying levels of self-control within their accounts of violence where having and lacking self-control was presented simultaneously. This demonstrates that talk about self-control is a discursive device that is used flexibly by perpetrators to manage their accountability for acts of IPV. © The Author(s) 2015.
