Abstract Sub-Neptunes with radii of 2–3 R ⊕ are intermediate in size between rocky planets and Neptune-sized planets. The orbital properties and bulk compositions of transiting sub-Neptunes provide clues to the formation and evolution of close-in small planets. In this paper, we present the discovery and follow-up of four sub-Neptunes orbiting M dwarfs (TOI-782, TOI-1448, TOI-2120, and TOI-2406), three of which were newly validated by ground-based follow-up observations and statistical analyses. TOI-782 b, TOI-1448 b, TOI-2120 b, and TOI-2406 b have radii of R p = 2.740 − 0.079 + 0.082 R ⊕ , 2.769 − 0.068 + 0.073 R ⊕ , 2.120 ± 0.067 R ⊕, and 2.830 − 0.066 + 0.068 R ⊕ and orbital periods of P = 8.02, 8.11, 5.80, and 3.08 days, respectively. Doppler monitoring with the Subaru/InfraRed Doppler instrument led to 2σ upper limits on the masses of <19.1 M ⊕, <19.5 M ⊕, <6.8 M ⊕, and <15.6 M ⊕ for TOI-782 b, TOI-1448 b, TOI-2120 b, and TOI-2406 b, respectively. The mass–radius relationship of these four sub-Neptunes testifies to the existence of volatile material in their interiors. These four sub-Neptunes, which are located above the so-called “radius valley,” are likely to retain a significant atmosphere and/or an icy mantle on the core, such as a water world. We find that at least three of the four sub-Neptunes (TOI-782 b, TOI-2120 b, and TOI-2406 b), orbiting M dwarfs older than 1 Gyr, are likely to have eccentricities of e ∼ 0.2–0.3. The fact that tidal circularization of their orbits is not achieved over 1 Gyr suggests inefficient tidal dissipation in their interiors.

We construct a renormalizable [Formula: see text] model with [Formula: see text] symmetry accommodating the observed pattern of fermion masses and mixings with Dirac CP violation phase. The smallness of the active neutrino masses arises from a combination of type I and type II seesaw mechanisms. Both normal and inverted neutrino mass ordering are viable in our model in which the obtained physical observables of the lepton sector are well consistent with the global fit of neutrino oscillation data [P. F. de Salas et al., Phys. Lett. B 782, 633 (2018)] while the CKM matrix is unity at tree level and the quark masses are in good agreement with the experimental data [Particle Data Group (M. Tanabashi et al.), Phys. Rev. D 98, 030001 (2018)]. Furthermore, the model also predicts an effective Majorana neutrino mass parameter of [Formula: see text] eV for normal hierarchy and [Formula: see text] for inverted hierarchy which are consistent with the constraints given in [P. F. de Salas et al., Phys. Lett. B 782, 633 (2018)].

ABSTRACT Introduction Every patient needs a comprehensive treatment planning. Dentists must consider the advantages and disadvantages of the available implant prosthetic options and match them to patient's expectations. Hybrid denture prosthesis is one, i.e., fabricated and retained by screw threaded into implant abutments, most of the time on four implants. Sometimes due to failure of an implant, the prosthesis needs to be replaced with a newer casting to accommodate the existing implants. Clinical consideration This article presents a novel technique, wherein the existing framework of the fixed prosthesis can be used to convert the fixed prosthesis to removable prosthesis on the existing implants, without recasting. Clinical significance The implant is economical and easily convertible from a fixed-fixed to a fixed-removable prosthesis. Hence, there is reduced morbidity, reduced cost, and an increased psychological comfort for the patient. How to cite this article Shetty PP, Gangaiah M, Chowdhary R.

Megophrys Kuhl and Van Hasselt are an Asian radiation of terrestrial frogs which are usually associated with montane forest (Mahony et al. 2017). The Annam horned frog (Megophrys intermedia) is reported from montane evergreen forest in Vietnam and Lao People’s Democratic Republic (Stuart 2005; Hendrix et al. 2008; Nguyen et al. 2009; Tran 2013; Orlov et al. 2015; IUCN 2017; Mahony et al. 2017). The IUCN Red List assessment for the species reports an elevational range of 782–1500 m asl (IUCN 2017) although the type locality was reported to be above 1500 m asl (Smith 1921), and Tran (2013) collected a specimen at 1515 m asl. Megophrys intermedia is assessed as Least Concern (IUCN 2017) and little is known about the reproductive behaviour and life history of the species. In Lam Dong Province (Vietnam), male M. intermedia call in March (Tran 2013); on the Langbian Plateau (Vietnam), male specimens are reported to call by day and by night from March to May and specimens called from within deep crevices between boulders in streams (Smith 1921); in Xe Kong Province (Laos), males call or guard egg clutches that are laid in water in July (Stuart 2005).

Full textAbstract:
ABSTRACT The FoxO forkhead transcription factors FoxO4 (AFX), FoxO3a (FKHR.L1), and FoxO1a (FKHR) represent important physiological targets of phosphatidylinositol-3 kinase (PI3K)/protein kinase B (PKB) signaling. Overexpression or conditional activation of FoxO factors is able to antagonize many responses to constitutive PI3K/PKB activation including its effect on cellular proliferation. It was previously shown that the FoxO-induced cell cycle arrest is partially mediated by enhanced transcription and protein expression of the cyclin-dependent kinase inhibitor p27kip1 (R. H. Medema, G. J. Kops, J. L. Bos, and B. M. Burgering, Nature 404:782-787, 2000). Here we have identified a p27kip1-independent mechanism that plays an important role in the antiproliferative effect of FoxO factors. Forced expression or conditional activation of FoxO factors leads to reduced protein expression of the D-type cyclins D1 and D2 and is associated with an impaired capacity of CDK4 to phosphorylate and inactivate the S-phase repressor pRb. Downregulation of D-type cyclins involves a transcriptional repression mechanism and does not require p27kip1 function. Ectopic expression of cyclin D1 can partially overcome FoxO factor-induced cell cycle arrest, demonstrating that downregulation of D-type cyclins represents a physiologically relevant mechanism of FoxO-induced cell cycle inhibition.

Full textAbstract:
This study examined the relationship of sports experience with ego development. A questionnaire was used to assess experience of Crisis, Exploration, and Commitment in the issues of Athletic Performance and of Being a Teammate in 782 adolescent Japanese athletes (423 boys, M age = 15.2 yr.; 359 girls, M age = 15.0 yr.). Their Ego Levels were assessed using the Washington University Sentence Completion Test. Correlations indicated that scores on Crisis, Exploration, and Commitment in the issues of Athletic Performance and Being a Teammate were generally associated with Ego Development. Multiple regression analyses indicated that, for boys, the issue of Athletic Performance was closely associated with Ego Development, while for girls, the issue of Being a Teammate was closely associated with Ego Development. Sports experience with crisis, exploration, and commitment may be related to accommodation, which is, in turn, related to ego development. The sex differences on issues related to ego development may be associated with differences in sex-role development for boys and girls.

Williams, Jeremy Huw. "Serialism, modality and poetic rhetoric in Alun Hoddinott's Five Poems of Gustavo Adolfo Bécquer, Op. 152 no. 2 (1994)." Thesis, Cardiff University, 2013. http://orca.cf.ac.uk/49267/.
Full textAbstract:
The last fifteen years of Alun Hoddinott’s life witnessed an unprecedented outpouring of works for solo voice, which seemed to coincide with a notable change of style – towards simpler textures, melodic lyricism and a greater concision of musical thought. This thesis examines the context and nature of this apparent change of style, focusing on text setting, poetic rhetoric, and harmonic and rhythmic vocabulary, with particular reference to the song cycle Five Poems of Gustavo Adolfo Bécquer, Op. 152 no. 2 (1994). Chapter 1 contextualizes the vocal music since 1994 within Hoddinott’s oeuvre, considering whether the later songs mark a genuine ‘late style’ or merely a shift of emphasis within an already established compositional approach. Chapter 2 examines in detail the rhetoric and structure of the poetry chosen by Hoddinott and the reflection of these poetic devices in the musical settings. Chapter 3 investigates the combination of modality and serialism in Hoddinott’s harmonic language, concluding with an analysis of the opening Andante of the Trio for violin, cello and piano, Op. 77 (1970). This chapter assesses his acknowledged debt to the modal writing of Bartók and the serial practices of Berg, manifested in Hoddinott’s use of whole-tone and octatonic scales as a basis for hexachordal structure. All these elements are then brought together in Chapter 4, an analysis of the Bécquer settings, which assesses the interaction of text and music. While the underlying structure of Hoddinott’s later music remains serial, its reduced rate of chromatic circulation means that the modal elements long present in his note rows now come clearly to the fore, contributing to the songs’ often striking changes of colour and texture. The appendices contain translations of the texts for the late solo baritone works (with original punctuation restored), along with a full works list, bibliography and discography.

Rowden, Clair. "Massenet, Marianne and Mary : Republican morality and Catholic tradition at the opera." Thesis, City University London, 2001. http://openaccess.city.ac.uk/7611/.
Full textAbstract:
The social and political practice of the French Third Republic resonated with a variety of contrasting ideologies which were reflected in cultural products and their reception, including opera. The operas of Jules Massenet, the most successful Parisian opera composer of his time, provide a good example of this kind of cultural mediation. A close examination of Massenet's operas will thus allow a re-evaluation of the complex interaction between art and society in musical culture at the end of the nineteenth century in France. Representative case-studies have been chosen, and the works are read in the contemporary Parisian context of moral and political debate. I examine the operas with respect to the choice of subject matter, the libretto and its genesis (especially transformations made in the process of creating a libretto), the music (both in it srelation to the specific drama and musical convention of the time), the staging and its messages, and the critical reception in the press. The main chapters are dedicated to the following issues: 1. Mary or Marianne? The social, moral and cultural context, particularly regarding women, is explored via a close reading of sources from the second half of the nineteenth century. 2. Le Pretre, la Femme et la Familie. Anticlericalism and Republicanism as reflected in Massenet's opera Herodiade and its reception history are addressed. Also discussed is the icon of the Republican mother, sexual desire and the question of divorce (hotly debated at the time of the opera's premiere). 3. Dreams of Decadence, or the Death of Positivism. Viewing the medium of the dream scene in Massenet's operas Herodiade and then Thai's, this chapter allows an exploration of the significance of the dream world and degeneracy in the'decadent and symbolist aestheticso f the last two decadeso f the nineteenthc entury in France, and their implications for the reigning Third-Republican positivist ideology. 4. La Pornocratie. This reading of the opera Thais addresses the way in which French fin-de-siecle art and society dealt with the `femme nouvelle'. Programmatic orchestral music in opera and its capacity to translate human passions and voice is examined.

Bohrer, Joceli Cirilo Soares. "Intonational strategies in ensemble singing." Thesis, City University London, 2002. http://openaccess.city.ac.uk/7645/.
Full textAbstract:
The aim of the research was to find out about intonational strategies in the performance situation. The singing voice was chosen as the appropriate subject for experimental work, due to its superior capability to define pitch as compared to other musical instruments. Ensemble singing was also required, as harmonic context may be important in the clarification of the issue, Chapter One, as an introduction to the subject, considers tuning systems and temperaments and briefly reviews the experimental literature on the subject. It also states the aim of the research. Chapter Two focuses on the theoretical aspects of the research, considering sonic relevant phenomena of psychoacoustics to the legacy of tuning systems and temperaments. Some thoughts on intonational strategies, reference frequencies and flexible temperament as desirable components of a sound intonational strategy are elaborated. An analysis of the motet Ave Veruin Corpus, by Mozart, as the chosen music piece for experimental work is carried out. Chapter 11ree deals with the delineation of experimental procedures for the evaluation of the intonational strategies adopted by singers in the performance situation. The recording sessions environment and the technical tools utilised in the experiments are described, as well as the technical procedures to carry out the measurements of the acquired data. As strict criteria had to be met regarding the performance situation, simultaneity of performance and the need to acquire individual data for analytical work, electrodes were attached to the neck of the singers, near the larynx, in order to carry out the recording sessions with the help of I-uyngogr2ph devices. Analytical issues arc also considered in the chapter, namely technical problems, errors and mistakes, as well as the implementation of intonational analyses and reference frequency calculations. Chapter Four presents a discussion on data measurements procedures, including guidelines for the determination of errors and mistakes and their symbology. Four recording sessions were carded out; two of them fulfilled 211th e necessary requirements. The singers' results are presented in chronological order. firstly, a quartet of singers from the Royal Academy of Music, and secondly, sixteen of the BBC Singers. Reference frequency results are also presented and discussed. Chapter Five deals with the intonational strategies as defined by the experimental work. It was discovered that no lbeorr&d modewl as followed throughout the music piece, but instead international procedures were guiding the singers while performing. Also, the two groups adopted different intonational strategies regarding reference frequencies. Alongside with the main issues of the research - intonational strategies regarding pitch behaviour and reference frequencies,p itch equalization within a choir section and text-related issues that amongst the most important topics that have been revealed by the results. Chapter Six comments on the new concepts brought about by the research. It also delineates some possibilities for future research work on the subject and related issues, especially vibrato singing & text articulation and absolute pitch. The Appendices contain images of the experimental work, diagrams of studio disposition for recording sessions, and analytical scores alongside with tuning tables that make it possible to represent graphically analytical values. They also provide means of performing acoustical replications of the results of analysis and singers. The core of the appendices volume is formed by the results of the singers' fundamental frequencies results and their graphical representation.

Groves, Stephen. "The sound of the English picturesque in the late eighteenth century : native vocal music and Haydn's The Seasons." Thesis, University of Southampton, 2011. https://eprints.soton.ac.uk/367391/.
Full textAbstract:
In eighteenth-century England, the art-forms of painting, poetry and gardening were often collectively labelled, the ‘sister arts’. The increasing interest taken in the apprehension and appraisal of scenes of English landscape by artists in these fields, alongside an emerging taste for nature ‘tourism’, gave rise to the term, the ‘picturesque movement’. English music was seldom considered as belonging to this ‘sisterhood’ or discussed as a medium for conveying artistic expressions of national scenic beauty. When the picturesque was discussed alongside music it was adopted as an analogy to explain the tactics of novelty and surprise deployed by contemporaneous German composers of instrumental music; these ‘plays’ with regularity and expectation were felt to be similar to the techniques of landscape gardeners who had studied and adopted the elements of surprise and irregularity observed in picturesque ‘beauty spots’. Recent musicological references to the picturesque have also preferred to employ it in this way in order to problematize the subversion of formal characteristics in the fantasias and unconventional symphonies by German composers. This thesis addresses the silent aporia in these discourses – namely the apparent absence of any participation in the picturesque by English composers, natives of the country most associated with the picturesque sensibility. Revealing the connections between the veneration of national landscape and eighteenth-century English vocal music, it is the ‘pictorialisms’ present in their texts, and their musical treatment, which are the focus of this project. In the process, secular song, the glee and national theatre music are positioned as appropriate sites for expressions of a uniquely English, painterly engagement with national landscapes, making possible reclamation of a neglected repertoire through the lens of the picturesque. And at the end of the project, Haydn’s oratorio, The Seasons, is shown to be as much a part of the English picturesque expression as a product of the German Enlightenment.

Meredith, Sharon. "Tuk in Barbados : the history, development and recontextualisation of a musical genre." Thesis, University of Warwick, 2002. http://wrap.warwick.ac.uk/91318/.
Full textAbstract:
This thesis is the first major investigation of tuk and documents an important part of Barbados' heritage. It also opens up opportunities for further research to be undertaken in Barbadian music and in related fields elsewhere in the Caribbean region. This thesis explores the history, development and recontextualisation of Barbadian tuk music. The history of Barbados is examined before considering Barbadian culture and how a Barbadian national identity was increasingly sought during the twentieth century, particularly after Independence. Music during the period of slavery, African music and British military music, the major influences on tuk, are explored before a study of the instruments, rhythms and repertoire of tuk. Types of tuk, and tuk-type musics elsewhere are examined and tuk is compared with other musics. Modern tuk musicians, their treatment of tuk, and how tuk has been, and continues to be, recontextualised is explored. The history, organisation and roles of the Barbados Landship, an organisation modelled on the British Royal Navy, but which never goes to sea, are considered together with the Landship's relationship with the tuk band. Finally, an overview of music and festivals in Barbados today places tuk in the country's musical scene. This thesis argues that tuk is predominantly a music that originated from imitating European military fife and drum bands, and that the African elements of it are to be found in rhythmic improvisation and some African retentions that have direct parallels with military fife and drum bands. It also argues that tuk exhibits characteristics similar to musics found elsewhere that can be attributed to the effects of the slave trade, colonialism and migration. In addition, the thesis argues that the Landship's relationship with the tuk band is a continuation of a naval tradition.

Full textAbstract:
We observed 82 healthy subjects, from both sexes, aged between 19 and 77 years. All subjects
performed two different tests: for being scientifically acknowledged, the first one was used as a
reference and it was a stress test (CPX). During the entire test, heart rate and gas exchange were
recorded continuously; the second, the actual object of this study, was a submaximal test (TOP).
Only heart rate was recorded continuously.
The main purpose was to determinate an index of physical fitness as result of TOP.
CPX test allowed us to individuate anaerobic threshold. We used an incremental protocol of 10/20
Watt/min, different by age.
For our TOP test we used an RHC400 UPRIGHT BIKE, by Air Machine. Each subject was
monitored for heart frequency. After 2 minutes of resting period there was a first step: 3 minutes of
pedalling at a constant rate of 60 RPM, (40 watts for elder subjects and 60 watts for the younger
ones). Then, the subject was allowed to rest for a recovery phase of 5 minutes. Third and last step
consisted of 3 minutes of pedalling again at 60 RPM but now set to 60 watts for elder subjects and
80 watts for the young subjects. Finally another five minutes of recovery.
A good correlation was found between TOP and CPX results especially between punctua l heart rate
reserve (HRR’) and anaerobic threshold parameters such as Watt, VO2, VCO2 .
HRR’ was obtained by subtracting maximal heart rate during TOP from maximal theoretic heart
rate (206,9-(0,67*age)).
Data were analyzed through cluster analysis in order to obtain 3 homogeneous groups. The first
group contains the least fit subjects (inactive, women, elderly). The other groups contain the
“average fit” and the fittest subjects (active, men, younger).
Concordance between test resulted in 83,23%.
Afterwards, a linear combinations of the most relevant variables gave us a formula to classify
people in the correct group.
The most relevant result is that this submaximal test is able to discriminate subjects with different
physical condition and to provide information (index) about physical fitness through HRR’.
Compared to a traditional incremental stress test, the very low load of TOP, short duration and
extended resting period, make this new method suitable to very different people.
To better define the TOP index, it is necessary to enlarge our subject sample especially by
diversifying the age range.

<p>Bakgrund: Finansiella mått har i alla tider använts av företag för att avläsa resultat. På senare tid har även vikten av mått på icke finansiella faktorer uppmärksammats. Som en följd har resultatmätningssystemet Balanced Scorecard vuxit fram. Balanced Scorecard sägs bland annat leda till förbättrad kommunikation och information inom organisationerna samt en ökad grad av måluppfyllelse. Trots den stora litteraturmängden rörandes Balanced Scorecard saknas information om vad som krävs för att organisationer skall kunna utvärdera om de väntade effekterna uppstår vid införandet av ett styrkort. Därför har vi valt att undersöka detta problem närmare. </p><p>Syfte: Syftet med uppsatsen är att identifiera de kriterier som krävs för att effekterna av Balanced Scorecard skall kunna utvärderas. </p><p>Genomförande: För att kunna identifiera de kriterier som krävs för att en utvärdering av effekter av Balanced Scorecard skall kunna genomföras, har vi valt att utföra intervjuer med organisationer som har använt sig av BSC under ett par år.

Full textAbstract:
This commentary will consider how I have developed and applied a number of compositional techniques, particularly in the area of rhythm and pulse, which I situate in relationship to postminimalism. In chapter 1 I contextualise my music by considering some manifestations of postminimalism, give the background to the development of my present aesthetic approach, and look at some definitions of postminimalism in order to clarify my own position in relation to both American and European (primarily Dutch) postminimal composition. In chapter 2 I examine the main aspects of my musical language, focussing on technical considerations in relation to the wider aesthetic context. In chapter 3, I will demonstrate how specific techniques, particularly rhythmic and permutational techniques, are applied in particular compositions, and how these techniques have developed over the last four years. Additionally, I consider how my work is informed by a social/political awareness, and how this has informed my choice of particular compositional strategies.

Parsons, John Lewis. "Stylistic change in violin performance 1900-1960 : with special reference to recordings of the Hungarian violin school." Thesis, Cardiff University, 2005. http://orca.cf.ac.uk/55396/.
Full textAbstract:
This thesis describes and analyses stylistic change in violin performance (c. 1900-1960) by examining the so-called Hungarian violin school as an exemplar of stylistic change in this period. The thesis uses examples from both written and recorded sources to examine shifts in the use of expressive fingering, vibrato and flexibility of rhythm and tempo. The sources used include: performing editions; treatises; and recordings. In respect of the study of stylistic change, the thesis argues that recordings provide a valuable research resource for assessing the theoretical use of expressive devices, as well as the prominence, character and actual application in performance of such devices. The thesis focuses on the relationship between a player's formal training and the cultural-aesthetic influences to which he/she was subsequently exposed, and also considers the relationship between performing theory and performing practice. Chapter one explores nineteenth-century French and German antecedents to the Hungarian school, before discussing the syllabus and pedagogy of Jeno Hubay in Budapest. The cheaper concludes with a case study of the changing approaches to technique and expression of Hubay's pupil, Josef Szigeti. Chapters two, three and four concentrate on the expressive devices used in the performances of violinists in the twentieth century: chapter two explores fingering; chapter three concerns vibrato; and chapter four addresses rhythm and tempo. The thesis shows that, in the case of the Hungarian school, players retained aspects of their initial training, but that other influences played a more decisive role in their evolution as mature artists. The thesis concludes by arguing that recorded sources have a vital and significant contribution to make to the field of twentieth-century performance practice.

Full textAbstract:
Abstract Indian mustard (Brassica juncea L.) is the most important oilseed crop of the state of Jharkhand in India, where 78% of the cultivable soil is acidic, causing a sizeable yield reduction. Potential seed yield from such soils cannot be realized within existing varieties and therefore a mutation breeding approach has been followed to isolate mutants tolerant to acidic soil. Three doses of gamma-rays (900 Gy, 1000 Gy and 1100 Gy) and a combined treatment of gamma irradiation and 0.3% EMS were used for induction of mutation in the varieties 'Shivani' and 'Pusa Bold'. A total of 139,720 M<sub>2</sub> plants (75,760 of 'Shivani' and 63,960 of 'Pusa Bold') were screened under acidic soil conditions (pH 4.8). A wide spectrum of variability for tolerance to soil acidity, earliness, seed colour, seed yield and yield components, and morphological traits was observed in the M<sub>2</sub> generation. True-breeding mutants for different traits were confirmed in the M<sub>3</sub> generation. Mutations were recorded in 'Shivani' and 'Pusa Bold', respectively, for secondary branch number (38 and 24), siliquae per plant (1223 and 562) and single plant seed yield (45.49 g and 34.84 g). In addition, a large spectrum of variability for morphological characters was identified.

Full textAbstract:
AbstractUrban Green Spaces (UGS) have several positive effects on Public Health, environmental quality, and cities’ resilience to climate change; UGS are crucial in urban regeneration actions and urban health purposes. Moreover, to better define the UGS’ health impacts, it is important to define and guarantee UGS’ proximity, accessibility, and quality. Aim of the research is a quali-quantitative assessment of the UGS in Italian metropolitan cities, taking Milan, Turin, Florence, and Bologna as preliminary case studies. One of the 1st phases was to draw up dynamic and descriptive GIS-based maps of the relationships between density of population and of urban fabric, UGS’ availability, and their accessibility. Only the areas with a size greater than 15,000 square meters were considered; three buffer zones of proximity were defined: 250, 500, and 750 m. By combining the UGS’ availability with the population’s density, it was possible to quantify the citizens included in the three buffer zones. From the 1st analysis, it is observed that about 90% of the population is served by a quality green area within a buffer area of 750 m; 78% by the buffer zone of 500 m; 49% by the buffer zone of 250 m. Both the elaborated maps and graphs obtained show how population is not equally served by close and accessible UGS. Their geo-localization it’s a preliminary quantitative step (process started in Italy with the introduction of regulations like green areas’ census, mapping, maintenance legislation, and strategic plans), but it’s even more crucial to evaluate the UGS’ quality in terms of accessibility, safety and security features, provision of services and paths.

Full textAbstract:
AbstractThis chapter assesses human health risks of inorganic arsenic (As) from drinking well water and consumption of rice irrigated by high-As groundwater in the Mekong River Delta. Geogenic inorganic As (iAs) occurring at elevated levels in groundwater has been detected in more than 70 countries. Among mostly rural residents relying on groundwater for drinking, this exposure has resulted in negative health consequences including visible skin lesions, multiple internal organ cancers, numerous invisible non-cancer health effects such as cardiovascular diseases, and premature deaths. In the Mekong River Delta (MRD, defined by elevation <10 m above sea level in this book), As issues in groundwater have been documented as early as 1999 in Cambodia, with literature reporting its occurrence in Vietnam since 2005. Since the early 2000s, efforts have been made to test for As in about 100,000 wells from Cambodia, Laos, Vietnam and Thailand. Here, a combined dataset with a total of 94,768 unique As tests was analyzed to illustrate the spatial patterns and to assess the health risks of drinking well water As in Cambodia and in southern Vietnam. Although knowledge is far more limited, an attempt was also made to examine the potential health risks associated with iAs exposure from rice, a major staple for the MRD. Here, irrigation using highly As enriched groundwater for rice cultivation has expanded this environmental health problem from the hydrosphere (water) to the geosphere (soil) and, in turn, the biosphere (rice, and ultimately humans). Of 41,928 tests in Cambodia, 35.8% exceeded 10 μg/L, the WHO guideline value for drinking water As, while 21.5% exceeded 50 μg/L, the Cambodian drinking water standard. Of 52,858 tests in Vietnam, the exceedance rate for 10 μg/L, which is also the Vietnamese drinking water standard, is 10.0%. High As wells, regardless of whether it is relative to 10 or 50 μg/L, are located in proximity to the main course of the Mekong-Bassac Rivers, especially within a 5 km distance. The vast majority (>98%) of high-As wells are located in low-lying areas, i.e. <25 m elevation in Cambodia and <10 m elevation in Vietnam. High-As wells occur frequently at shallow depths (<70 m) across the MRD but also at deeper depths (300–500 m) in Vietnam. Due to the clustering of high As wells along the Mekong-Bassac Rivers, extreme human health tolls are identified in 11 districts of Cambodia and 3 districts of Vietnam with a population attributable fraction exceeding 0.1, meaning that >1 in every 10 adult deaths is solely due to drinking water As exposure. The annual excess deaths attributable to arsenic exposure alone is 1204 in Cambodia and 1486 in Vietnam, or 1 in every 27 adult deaths and 1 in every 78 adult deaths, respectively. In addition to uncertainties in bioavailability and toxicity of iAs in rice grains, soil and rice As data, especially rice As speciation data needed for risk assessment, are still limited in the MRD.

Full textAbstract:
The Coweeta LTER Program represents the eastern deciduous forests of the southern Appalachian Mountains in the United States. Coweeta Hydrologic Laboratory was established in 1934 and hence has a long record of climate measurement and vegetation response to both natural and human disturbance (Swank and Crossley 1988). The general climate of the area is classified as marine humid temperate because of high moisture and mild temperatures (Critchfield 1966; Swift et al. 1988). These conditions have favored the evolution of high species diversity in organisms in the southern Appalachians at many levels. In recent years, however, Coweeta has experienced several droughts that have caused significant tree growth reduction and increased mortality rates (Swift et al. 1990; Clinton et al. 1993; Vose and Swank 1994; McNulty and Swank 1995). In this chapter, we describe the general climate and features of Coweeta as well as the impact of droughts on tree growth and mortality. The timescale of this climate variability is annual, with the potential for preexisting soil moisture conditions either providing a buffer or further exacerbating the drought conditions. Mean annual precipitation at Coweeta Hydrologic Laboratory (latitude 35º14' N, longitude 83º26' W) varies from 1798 mm at the base climate station (686 m) to 2373 mm at the high-elevation Mooney Gap climate station (1364 m). Mean annual growing season precipitation, defined as May to October, is 782 mm at the base climate station (figure 3.1). Mean annual streamflow from watershed 18, a low-elevation reference watershed, is 1011 mm or 56% of precipitation (figure 3.1). Short-duration thundershowers at Coweeta are typical for midsummer and fall with occurrences of large rainfalls stimulated by tropical disturbances near the Atlantic or Gulf coasts. Forty-nine percent of the 133 storms each year have a total precipitation amount less than 5 mm, and 69% of the annual precipitation falls with an intensity less than 10 mm per hour. Snow is a minor part of the annual precipitation, averaging 2–5% depending on elevation. Snow cover rarely lasts for more than 3 or 4 days, even on the upper slopes.

Full textAbstract:
A mobile coupon is a new form of sales promotion tool used by marketers to advertise their products or services. This chapter examines key factors in consumers’ intention to use mobile coupons (m-coupon). The authors considered several factors and developed the conceptual framework underpinned on an extended Technology Adoption Model (TAM). The data analysis was based on 781 valid responses from four locations in Malaysia. The results indicate that perceived usefulness, attitude, and social factors influence the behavioral intention of consumers to use mobile coupons. Consistent with prior studies, perceived usefulness, and perceived ease of use were found to be significant antecedents of the attitude towards using m-coupons. The results also indicate that gender, income, and price consciousness are significant moderating variables.

Full textAbstract:
Abstract This paper reports the steps of a cathodic protection upgrade of a three year old deep water platform (the Cognac structure, Mississippi Canyon 194A) installed in 1977/78. These steps include obtaining results from an ROV survey, using the survey data to calculate added currents needed to upgrade cathodic protection of the platform, achieving retrofit anode installation using then novel methods, and following-up with CP surveys showing the success of the upgrade. We calculated that 3,100 amperes of additional current applied at depths from 250' to 1,050' feet (76 m to 320 m) would be needed to achieve full cathodic protection of the well conductors and jacket of Cognac. Approximately 1100 additional aluminum anodes were installed during the early 1980's, using two novel installation methods. Installed cost was estimated at $5,4MM. Potentials since the time of the upgrade have been very satisfactory.

Full textAbstract:
Mixing is a critical operation in numerous industrial processes, traditionally performed in agitated tanks to ensure homogenization. Despite its importance, the design of tanks and impellers is often neglected during agitation system selection, resulting in excessive energy consumption and inefficient mixing. To mitigate these challenges, Computational Fluid Dynamics (CFD) serves as a powerful tool for analyzing tank hydrodynamics and quantifying mixing times. CFD employs mathematical models to simulate mass, heat, and momentum transport phenomena within fluid systems. Among the latest advancements in modeling stirred tank hydrodynamics is Smoothed Particle Hydrodynamics (SPH), a mesh-free Lagrangian approach that tracks individual particles characterized by properties such as mass, position, velocity, and pressure. SPH provides significant advantages over traditional mesh-based methods by accurately capturing fluid behavior through particle interactions. In this study, the performance of three impellers�double ribbon, paravisc, and hybrid�was evaluated based on hydrodynamics and mixing times during the homogenization of water and ethanol in a 0.5 L stirred tank. The tank and impellers were meticulously designed, operating at 70% capacity, with the fluids exhibiting the following rheological properties: ?1 = 1000 kg/m�, ?2 = 789 kg/m�, �1 = 1E-6 m�/s, and �2 = 1.52E-6 m�/s. The simulations were conducted under turbulent flow conditions (Reynolds number of 10,000) for a duration of 2 minutes using the DualSPHysics software. The stirring speed was set at 34 rpm, and the initial particle spacing was configured to 1 mm, generating 270,232 fluid particles and 187,512 boundary particles representing the tank and agitator. The analysis included velocity profiles, flow patterns, vorticity, divergence, and density fields to assess mixing performance. The Q-criterion was employed to discern the dominance of rotational or deformational motion and to identify stagnation zones. The results revealed that the double ribbon impeller exhibited superior performance, achieving 88.28% mixing within approximately 100 seconds, while the paravisc and hybrid impellers reached mixing efficiencies of 12.36% and 11.8%, respectively. These findings underscore the potential of SPH as a robust computational approach for linking hydrodynamic behavior with mixing efficiency and identifying key parameters to optimize mixing processes.

Full textAbstract:
Abstract The field Höflein is located 10 km NW of Vienna. Gas condensate is produced out of 9 wells at the dew point of 28.1 MPa and 78°C. The reservoir fluid is lean but contains more than 16% CO2. Lab test preceded the selection of the inhibitor for the carbon steel. Critical parts of the installations had 13% Cr steel. This paper describes the inhibitor testing procedures and the monitoring of the corrosion process by OMV Austria. The produced reservoir fluids and the critical components in the water (Cl, Fe, pH, inhibitor concentration) have been recorded over the years in various locations. Fluid analysis, corrosion coupon data, visual inspection and caliper measurements of field installation document a high degree of protection. Recently the reservoir underwent a reevaluation in which the reserves could be doubled. This gave the incentive to produce at higher rates (from 8 to probably 16 m/s). Inhibitors of the 3rd generation that work even under high velocities were applied. For this case a test loop in the laboratory is described which allows for emulating the high velocity flow conditions that are planned in the field and where the inhibitors can be tested and selected.

The intercritical heat treatment effect on the mechanical properties of the API 5L X65 steel, microalloyed with Ti and Nb, widely used in welded structures, was investigated. The embrittlement, observed by several authors in the intercritical region of the heat affected zone of welds performed in HSLA steels, is closely related to the volume fraction of M-A constituent, formed in the cooling. Just upon the homogenization and normalizing heat treatments, the specimens were submitted to different intercritical heat treatments, performed at 780 °C for 30 minutes and cooled with various Δt8/5 rates, with the purpose of varying the microstructure. High fracture toughness was obtained with the lower cooling rate. Also, it was verified that the low M-A constituent volume fraction was not enough to promote reduction on the fracture toughness.

Full textAbstract:
Beamforming in reverberant environments is important to locate and quantify noise sources in turbofan engine nacelles, automobile interiors, factories, and architectural settings. In order to validate and explore the limits of this approach, a beamforming experiment was conducted in a reverberation chamber using a 32 channel planar phased array and a B&K sound power source. In the reference configuration, the source was located 2 m from the 1.1 m diameter array, and neither was close to the chamber walls. A less-demanding case was constructed by adding some foam absorber to the room to reduce reverberation. A difficult case resulted when the source was placed 5 m from the array, about 1 m from a corner of the chamber. Conventional frequency-domain beamforming with diagonal deletion was applied. The sound source was accurately located at the 2 m distance, with and without the added absorber. In the 5 m case, the sound source could be located at only a few frequencies and only when the processing bandwidth was increased from 48.8 Hz to 781 Hz. Processing individual eigenvectors of the CSM separated the direct and reflected source in 5 m case. The error in the deduced broadband sound power was 0.72 dB in the baseline case, 1.47 dB with the added absorber, and 5.41 dB with the speaker in the corner. Application of CLEAN-SC did not improve the accuracy of the corner results. Use of a Green’s function that attempts to account for reflections was ineffective. It is concluded that beamforming in highly reverberant environment with the free space Green’s function is practical, provided the array is designed and positioned correctly for the environment and source location.

In this study, we examine potential temporal changes in coda Q values for two significant Canadian earthquakes in different tectonic environments: the 2017 (Mw 5.9) Barrow Strait earthquake along Canada's northern margin and the 2012 (Mw 7.8) Haida Gwaii subduction earthquake on Canada's west coast. Waveforms from 124 earthquakes (2.0 &amp;lt;/= M &amp;lt;/= 4.6) for ~30 years prior to the January 8, 2017 Barrow Strait earthquake and 66 events (mainly aftershocks of M 2.0-5.3) in about 4 years after the mainshock recorded by the closest seismic station (RES) of the Canadian National Seismograph Network (CNSN) were utilized in this study. Based on our analysis, overall average of Q0 (Q at 1 Hz) decreased from 92 (before the mainshock) to 81. The most significant decrease in the frequency range between 2 and 16 Hz is observed for areas corresponding to ellipse parameter a2 of 50, 70 and 80 mainly related to aftershock activity. Precursory Q changes could not be evaluated before the mainshock due to the lack of reported seismicity within 100 km of the recording seismic station for almost 2 years from April 2015 to January 2017. Coda Q values before and after the October 28, 2012 Haida Gwaii earthquake in British Columbia show a similar pattern. Waveforms from 249 earthquakes (2.0 &amp;lt;/= M &amp;lt;/= 4.9) in 2 years before the mainshock and 498 events (2.5 &amp;lt;/= M &amp;lt;/= 6.3) in 2 years after the mainshock recorded by the three closest seismic stations of the CNSN were utilized. Overall average of Q0 decreased from 89 (before the mainshock) to 69 (station BNB), from 90 to 79 (station DIB) and from 86 to 78 (station VIB). In general, these results are in agreement with other global studies that show a decrease in Q0 following a major earthquake, likely the result of increased fracturing and fluids in the epicentral region.

Current dam discharge patterns in Noxon Rapids Reservoir reduce concentration and exposure times (CET) of herbicides used for aquatic plant management. Herbicide applications during periods of low dam discharge may increase herbicide CETs and improve efficacy. Applications of rhodamine WT dye were monitored under peak (736 to 765 m³ s⁻¹) and minimum (1.4 to 2.8 m³ s⁻¹) dam discharge patterns to quantify water-exchange processes. Whole-plot dye half-life under minimal discharge was 33 h, a 15-fold increase compared with the dye treatment during peak discharge. Triclopyr concentrations measured during minimum discharge within the treated plot ranged from 214 ± 25 to 1,243 ± 36 μgL⁻¹ from 0 to 48 h after treatment (HAT), respectively. Endothall concentrations measured during minimum discharge in the same plot ranged from 164 ± 78 to 2,195 ± 1,043 μgL⁻¹ from 0 to 48 HAT, respectively. Eurasian watermilfoil (Myriophyllum spicatum L.) occurrence in the treatment plot was 66%, 8%, and 14% during pretreatment, 5 wk after treatment (WAT), and 52 WAT, respectively. Myriophyllum spicatum occurrence in the nontreated plot was 68%, 71%, and 83% during pre-treatment, 5 WAT, and 52 WAT, respectively. Curlyleaf pondweed (Potamogeton crispus L.) occurrence in the treatment plot was 29%, 0%, and 97% during pretreatment, 5 WAT, and 52 WAT, respectively. Potamogeton crispus increased from 24% to 83% at 0 WAT to 52 WAT, respectively, in the nontreated plot. Native species richness declined from 3.3 species per point to 2.1 in the treatment plot in the year of treatment but returned to pretreatment numbers by 52 WAT. Native species richness did not change during the study in the nontreated reference plot. Herbicide applications during periods of low flow can increase CETs and improve control, whereas applications during times of high-water flow would shorten CETs and could result in reduced treatment efficacy.

Heat production (HP) or energy expenditure for activity (EEa) is of fundamental nutritional importance for livestock because it determines the proportion of ingested nutrients available for productive functions. Previous estimates of EEa are unreliable and vary widely with different indirect methodologies. This leads to erroneous nutritional strategies, especially when intake on pasture does not meet nutritional requirements and supplementation is necessary for acceptable production. Therefore, the objective of this project was to measure EEa in different classes of livestock (beef cattle and goats) over a wide range of ecological and management conditions to develop and evaluate simple means of prediction. In the first study in Israel, small frame (SF) and large frame (LF) cows (268 and 581 kg) were monitored during spring, summer, and autumn. Feed intake by SF cows per unit of metabolic weight was greater (P < 0.001) than that by LF cows in both spring and summer and their apparent selection of higher quality herbage in spring was greater (P < 0.10) than that of LF cows. SF cows grazed more hours per day and walked longer distances than the LF cows during all seasons. The coefficient of specific costs of activities (kJ•kg BW-0.75•d-1) and of locomotion (J•kg BW-0.75•m-1) were smaller for the SF cows. In the second study, cows were monitored in March, May, and September when they grazed relatively large plots, 135 and 78 ha. Energy cost coefficients of standing, grazing, and horizontal locomotion derived were similar to those of the previous study based on data from smaller plots. However, the energy costs of walking idle and of vertical locomotion were greater than those found by Brosh et al. (2006) but similar to those found by Aharoni et al. (2009). In the third study, cows were monitored in February and May in a 78-ha plot with an average slope of 15.5°, whereas average plot slopes of the former studies ranged between 4.3 and 6.9°. Energy cost coefficients of standing, grazing, and walking idle were greater than those calculated in the previous studies. However, the estimated energy costs of locomotion were lower in the steeper plot. A comparison on a similar HP basis, i.e., similar metabolizable energy (ME) intake, shows that the daily energy spent on activities in relation to daily HP increased by 27% as the average plot slope increased from 5.8 and 6.02 to 15.5°. In the fourth study, cows grazing in a woodland habitat were monitored as in previous studies in December, March, and July. Data analysis is in progress. In the first US experiment, Boer and Spanish does with two kids were used in an experiment beginning in late spring at an average of 24 days after kidding. Two does of each breed resided in eight 0.5-ha grass/forb pastures. Periods of 56, 60, 63, 64, and 73 days in length corresponded to mid-lactation, early post-weaning, the late dry period, early gestation, and mid-gestation. EEa expressed as a percentage of the ME requirement for maintenance plus activity in confinement (EEa%) was not influenced by stocking rate, breed, or period, averaging 49%. Behavioral activities (e.g., time spent grazing, walking, and idle, distance traveled) were not highly related to EEa%, although no-intercept regressions against time spent grazing/eating and grazing/eating plus walking indicated an increase in EEa% of 5.8 and 5.1%/h, respectively. In the second study, animal types were yearling Angora doeling goats, yearling Boer wether goats, yearling Spanish wether goats, and Rambouilletwether sheep slightly more than 2 yr of age. Two animals of each type were randomly allocated to one of four pastures 9.3, 12.3, 4.6, and 1.2 ha in area. The experiment was conducted in the summer with three periods, 30, 26, and 26 days in length. EEa% was affected by an interaction between animal type and period (Angora: 16, 17, and 15; Boer: 60, 67, and 34; Spanish: 46, 62, and 42; sheep: 22, 12, and 22% in periods 1, 2, and 3, respectively (SE = 6.1)). EEa% of goats was predicted with moderate accuracy (R2 = 0.40-0.41) and without bias from estimates of 5.8 and 5.1%/h spent grazing/eating and grazing/eating plus walking, respectively, determined in the first experiment; however, these methods were not suitable for sheep. These methods of prediction are simpler and more accurate than currently recommended for goats by the National Research Council.

Full textAbstract:
The Jockey Hollow section and the New Jersey Brigade Area of Morristown National Historical Park (MORR) are predominantly comprised of upland oak-hickory forests that have regrown over the past 200 years from previous land uses. The forest is being damaged by two major stressors, a large population of white-tailed deer and an abundance of non-native, invasive shrubs and herbaceous species. This study explores changes to the forest over 26 years and suggests management techniques to avoid future degradation. The forest is typical of many upland stands in the region, and studies here would be applicable to many lands controlled by the National Park Service and to many public and private land owners. In 1995, 18 vegetation experimental plots were established in the forest, each 20 x 20 m. Ten plots were in areas that had no non-native, invasive plants. The other eight plots had invasive species. All trees, shrubs and a sampling of herbs were recorded in each of the 18 plots. At that time, no GPS technology was available and handwritten maps were used to record locations. The plots were revisited and resurveyed in 2001; however, only 13 plots were found. This 2021 study is a new survey of the plot conditions. The investigators were able to relocate 17 of the original plots. New GPS locations were recorded for these 17 plots to facilitate future studies. The goal of the study was to test if changes over 26 years in forest conditions differed between the original invaded plots as compared to the uninvaded plots. Also, these data will allow us to measure the progress of invasion into previously uninvaded areas. Together, these results will allow the forest managers to focus attention on the most aggressive plant invaders and to understand the fate of this forest type that is being challenged by deer and non-native plants. Over the last 26 years there has been no hunting for deer here. Also, the plots were not within the few deer exclosures at MORR; deer were able to enter the landscape from surrounding heavily wooded areas. Data were collected in four layers of vegetation – mature trees, saplings, shrubs, and herbaceous groundcovers. The mature trees in the invaded forest plots demonstrated declining trends. The species richness declined by 6%, the average number of trees declined by 30%, white ash and flowering dogwood had the most losses, and basal area did not increase over time because very few new saplings grew into mature tree sizes. The uninvaded plots’ mature trees also revealed a 20% declined in richness, number of trees declined by 18%, the greatest losses occurred for red maple and black birch, but basal area increased slightly due to growth of large persisting trees. Saplings in the invaded forest experienced declines over the 26 years. Species richness declined by 38%, number of native saplings decreased by 44%, and number of invasive saplings increased by 600%. In the uninvaded forest, the conditions and trends were variable. Richness decreased by 21%, no invasive saplings found, number of native saplings increased by 37% (due to increases in American beech). With American beech excluded, the number of native saplings decreased by 60%. In both forest types, the declining number of native saplings was primarily caused by excessive deer damage. For the shrub layer in invaded plots, Japanese barberry stems increased by 122% by 2001 and 276% by 2021. Barberry became the dominant species. Similarly, wineberry stands increased 486% in 2001 and 157% for 2021. It is now the second most common species. However, in the uninvaded plots there was no significant increase in the number of barberry stems and wineberry was not present in 1995 or 2001, and only averaged 1.5 stems per plot in 2021. Neither species has a significant presence now and eradication is possible. A major finding is that the process of invasion of these shrubs over 26 years is very slow. For the herbaceous plants, in the invaded plots there was a sharp decrease in cover by 2021 due to the competitive impact by the abundant invasive shrubs. The invasive Japanese stiltgrass declined 86% in cover and native Carex (sedge) species declined by 78%. In the uninvaded forest plots, stiltgrass was present in very low amounts and did not increase significantly over 26 years. The number of quadrats with any stiltgrass only increased from 3 to 5 over the 26 years. These data show that stiltgrass invades slowly in the uninvaded plots, but in the invaded plots it was greatly replaced by invasive shrubs. Overall, the rate of change of the native herb cover was slow. Together, these data suggest that currently uninvaded forest areas can be protected by monitoring and rigorously eliminating any initial invasions by non-native shrubs and herbs. Once these species reach a significant presence in number of stems or cover in a plot they explode in number. Early intervention when invasive plants first appear is the most practical management tool. Reduction of deer density will also increase the reproductive potential and sustainability of our main forest tree species. Planting of new young canopy tree species, with protection from deer, can retard the ability of invasive plants to begin new populations.
