"The Interdecadal Reverse of the Relationship and Feedback Mechanism between Sea Surface Temperature and Evaporation over the Indian Ocean during Boreal Autumn". Journal of Climate 33, n.º 23 (1 de dezembro de 2020): 10205–19. http://dx.doi.org/10.1175/jcli-d-20-0009.1.

AbstractThe linkage between sea surface temperature (SST) and evaporation (EVP) plays an important role in air–sea interactions. In this study, the interaction mechanism of SST and EVP during boreal autumn was studied using correlation analysis, composite analysis, the EVP decomposition method, and singular value decomposition. The results showed that the correlation between SST and EVP in the Indian Ocean was reversed from positive to negative in the late 1990s. The significant positive SST–EVP relationship was attributed to the Indian Ocean basin mode forcing upon EVP during 1980–90. The decrease in wind speed–induced EVP and SST warming led to a significant negative SST–EVP relationship during 2005–15. Moreover, the negative SST–EVP correlation occurred when the Indian Ocean dipole (IOD) and subtropical Indian Ocean dipole (SIOD) exhibited inverse phases. The low-level moisture–EVP–SST feedback dominated the negative SST–EVP correlation in the negative IOD and positive SIOD (nIOD–pSIOD) pattern, whereas the wind–EVP–SST feedback played the leading role in the positive IOD and negative SIOD (pIOD–nSIOD) pattern. The EVP anomalies induced by the low-level anomalous anticyclone and cyclone were the main causes of the SST anomalies with inverse phases of the IOD and SIOD. The correlation between the SST and EVP reversal from positive to negative implies that the effect of the atmosphere on the ocean is as important as the external forcing of the ocean on the atmosphere.

In a competitive global market, organizations are striving to retain the best talent by providing sustainable employer value proposition (EVP); ‘value proposition' employees perceive or expect from their employer. Although EVP is conceptually appealing, there has been little systematic effort to empirically examine the dimensions of EVP. Information technology companies are adopting strategies to provide proposition that attract and retain employees. This paper identifies the attributes of EVP from the perspective of employees working in Information Technology companies in India. A scale is developed and validated to measure EVP on a sample size of 474. EVP scale was tested for its factor structure, reliability and validity. The results indicated that EVP scale comprised of five attributes; developmental value, inspirational value, work environment value, work value, and work life balance. The finding of the research is discussed; limitations noted; recommendations for enhancing EVP in IT companies, and future research directions.

Yu, Lisan. "Global Variations in Oceanic Evaporation (1958–2005): The Role of the Changing Wind Speed". Journal of Climate 20, n.º 21 (1 de novembro de 2007): 5376–90. http://dx.doi.org/10.1175/2007jcli1714.1.
Texto completo da fonteResumo:
Abstract Global estimates of oceanic evaporation (Evp) from 1958 to 2005 have been recently developed by the Objectively Analyzed Air–Sea Fluxes (OAFlux) project at the Woods Hole Oceanographic Institution (WHOI). The nearly 50-yr time series shows that the decadal change of the global oceanic evaporation (Evp) is marked by a distinct transition from a downward trend to an upward trend around 1977–78. Since the transition, the global oceanic Evp has been up about 11 cm yr−1 (∼10%), from a low at 103 cm yr−1 in 1977 to a peak at 114 cm yr−1 in 2003. The increase in Evp was most dramatic during the 1990s. The uncertainty of the estimates is about ±2.74 cm yr−1. By utilizing the newly developed datasets of Evp and related air–sea variables, the study investigated the cause of the decadal change in oceanic Evp. The decadal differences between the 1990s and the 1970s indicates that the increase of Evp in the 1990s occurred over a global scale and had spatially coherent structures. Larger Evp is most pronounced in two key regions—one is the paths of the global western boundary currents and their extensions, and the other is the tropical Indo-Pacific warm water pools. It is also found that Evp was enlarged primarily during the hemispheric wintertime (defined as the mean of December–February for the northern oceans and June–August for the southern oceans). Despite the dominant upward tendency over the global basins, a slight reduction in Evp appeared in such regions as the subtropical centers of the Evp maxima as well as the eastern equatorial Pacific and Atlantic cold tongues. An empirical orthogonal function (EOF) analysis was performed for the yearly winter-mean time series of Evp and the related air–sea variables [i.e., wind speed (U) and air–sea humidity differences (dq)]. The analysis suggested a dominant role of the wind forcing in the decadal change of both Evp and dq. It is hypothesized that wind impacts Evp in two ways. The first way is direct: the greater wind speed induces more evaporation by carrying water vapor away from the evaporating surface to allow the air–sea humidity gradients to be reestablished at a faster pace. The second way is indirect: the enhanced surface wind strengthens the wind-driven subtropical gyre, which in turn drives a greater heat transport by the western boundary currents, warms up SST along the paths of the currents and extensions, and causes more evaporation by enlarging the air–sea humidity gradients. The EOF analysis performed for the time series of the global annual-mean Evp fields showed that the first three EOF modes account for nearly 50% of the total variance. The mode 1 variability represents the upward trend in Evp after 1978 and is attributable to the increased U, and the mode 2 variability explains much of the downward trend in Evp before 1978 and is correlated to the global dq variability. The EOF mode 3 of Evp captures the interannual variability of Evp on time scales of the El Niño–Southern Oscillation, with the center of action over the eastern equatorial Pacific.

The purpose of this article is to obtain a better understanding of the extended variational principle (EVP). The EVP is a formula for the thermodynamic pressure of a statistical mechanical system as a limit of a sequence of minimization problems. It was developed for disordered mean-field spin systems, spin systems where the underlying Hamiltonian is itself random, and whose distribution is permutation invariant. We present the EVP in the simpler setting of classical mean-field spin systems, where the Hamiltonian is non-random and symmetric. The EVP essentially solves these models. We compare the EVP with another method for mean-field spin systems: the self-consistent mean-field equations. The two approaches lead to dual convex optimization problems. This is a new connection, and it permits a generalization of the EVP.

The growing demand for ESP courses, due not only to the use of English as a lingua franca in a globalized professional world but also to the relatively recent requirements of “internationalized” university degrees, has made the teaching of English for Special Purposes, with the areas and the language teaching approaches (EOP, EAP, EVP) it has come to include, increasingly reliant on the use of specialized EFL textbooks. However, the ESP books available in the market still might not cover all the non-linguistic specialized university disciplines, or they might be too costly and time-consuming for short, elective, and pass/fail EFL courses worth few ECTS credits.This paper will report on the author’s experience of teaching a University Business Communication course without the use of textbooks, and with significant resort to online free educational resources and “non-desktop” technologies, materials and tools, which have also been exploited to involve students in the preparation of flipped lessons and the creation of their own educational material. The course-specific features and students’ outcomes, especially in terms of competence and skill development, will be described with a brief analysis of the pros and cons of transforming a formal educational setting in an informal language learning experience.

The Nerang Broadbeach Roadway (NBR) embankment in Australia is founded on soft clay deposits. The embankment sections were preloaded and surcharged-preloaded to limit the post-construction deformation and to avoid stability failure. In this paper, we discuss the NBR embankment’s geology, geotechnical properties of the subsurface, and long-term field monitoring data from settlement plates and piezometers. We demonstrate a comparison of cone penetration test (CPT) and piezo cone dissipation test (CPT-u) interpreted geotechnical properties and the NBR embankment’s foundation stratification with laboratory and field measured data. We also developed two elasto-viscoplastic (EVP) models for long-term performance prediction of the NBR embankment. In this regard, we considered both the associated and the non-associated flow rule in the EVP model formulation to assess the flow rule effect of soft clay. We also compared EVP model predictions with the Modified Cam Clay (MCC) model to evaluate the effect of viscous behavior of natural Estuarine clay. Both EVP models require six parameters, and five of them are similar to the MCC model. We used the secondary compression index of clay in the EVP model formulations to include the viscous response of clay. We obtained numerical models’ parameters from laboratory tests and interpretation of CPT and CPTu data. We observed that the EVP models predicted well compared with the MCC model because of the inclusion of soft clay’s viscosity in the EVP models. Moreover, the flow rule effect in the embankment’s performance predictions was noticeable. The non-associated flow rule EVP model predicted the field monitoring settlement and pore pressure better compared to the MCC model and the associated flow EVP model.

Purpose The purpose of this paper is to examine the link between employee value proposition (EVP) dimensions, employee commitment and organisational citizenship behaviours (OCBs) in organisations. Design/methodology/approach This cross-sectional study collected data from 134 employees of a government department using a survey method. The collected data were analysed with a regression method using Statistical Package for Social Sciences version 24. Findings The regression analysis shows that perceived organisational support, and work environment (WE) influence employee commitment. Also, the relationship between organisational commitment (OC) and OCB was found to be significant. The analysis also confirms that OC mediates the relationship between the EVP variables and OCB. Research limitations/implications This study is cross-sectional research, future studies may adopt a longitudinal method or multi-sourced data for further research insights. Due to the adopted research design, the findings should be interpreted with this in mind. Practical implications This study helps to understand the impact of EVP attributes on employee commitment in organisations. The finding would benefit organisations on the need to enhance EVP fulfilment, and its benefits findings from the study show perceived organisation support and WE affects OC while OC affects OCB. It is crucial for organisations to consider and align EVP strategies in their people management strategies. Originality/value This study contributes to the EVP theory by analysing the role of affiliation dimension of the EVP on employee commitment. Prior research appears to have neglected the influence of the EVP on employee commitment.

The institution compete smartly to attract the generation Y talent from workforce market. After they get the best talent, they face significant challenges to retain them by boosting their motivation, job satisfaction, and engagement in order to achieve outstanding performance. On the other hand, employee value proposition (EVP) is one of the factors to improve the employee’s commitment. The institution with the clear EVP will enhance the employee’s commitment. Many literatures describe about the characteristic of generation Y and also with EVP. But, only few researcher explain about the EVP in the perspective of generation Y. This journal is trying to research what are the dominant factors of employee value proposition (EVP) from the perspective of generation Y. The respondents are the generation Y who work at the one of the institution in Indonesia.

Texto completo da fonteResumo:
We develop a non-associated flow rule (NAFR)-based elasto-viscoplastic (EVP) model for isotropic clays. For the model formulation, we introduce the critical state soil mechanics theory (CSSMT), the bounding surface theory and Perzyna’s overstress theory. The NAFR based EVP model comprises three surfaces: the potential surface, the reference surface and the loading surface. Additionally, in the model formulation, assuming the potential surface and the reference surface are identical, we obtain the associated flow rule-based EVP model. Both EVP models require seven parameters and five of them are identical to the Modified Cam Clay model. The other two parameters are the surface shape parameter and the secondary compression index. Moreover, we introduce the shape parameter in the model formulation to control the surface shape and to account for the overconsolidation state of clay. Additionally, we incorporate the secondary compression index to introduce the viscosity of clay. Also, we validate the EVP model performances for the Shanghai clay, the San Francisco Bay Mud (SFBM) clay and the Kaolin clay. Furthermore, we use the EVP models to predict the long-term field monitoring measurement of the Nerang Broadbeach roadway embankment in Australia. From the comparison of model predictions, we find that the non-associated flow rule EVP model captures well a wide range of experimental results and field monitoring embankment data. Furthermore, we also observe that the natural clay exhibits the flow rule effect more compared to the reconstituted clay.

Los espacios verdes públicos (EVP) brindan servicios sociales y ambientales a la comunidad urbana. Se diagnostica y analiza la presencia, superficie y distribución de los EVP del municipio de Santa Fe (Argentina), en relación con cuatro áreas de calidad de vida establecidas en un estudio previo. Esta aproximación se apoya en una serie de indicadores que toman datos de fuentes secundarias y primarias. Los resultados muestran que en Santa Fe la oferta, extensión, presencia y densidad de los EVP difieren entre las distintas áreas de calidad de vida, donde la mayor disponibilidad de estos espacios se encuentra en los lugares con mayor calidad de vida. La normativa municipal habría favorecido la proliferación de EVP de tamaño pequeño.

Texto completo da fonteResumo:
Forming complex geometries using the casting process is a big challenge for bulk metallic glasses (BMGs), because of a lack of time of the window for shaping under the required high cooling rate. In this work, we open an approach named the “entire process vacuum high pressure die casting” (EPV-HPDC), which delivers the ability to fill die with molten metal in milliseconds, and create solidification under high pressure. Based on this process, various Zr-based BMGs were prepared by using industrial grade raw material. The results indicate that the EPV-HPDC process is feasible to produce a glassy structure for most Zr-based BMGs, with a size of 3 mm × 10 mm and with a high strength. In addition, it has been found that EPV-HPDC process allows complex industrial BMG parts, some of which are hard to be formed by any other metal processes, to be net shaped precisely. The BMG components prepared by the EVP-HPDC process possess the advantages of dimensional accuracy, efficiency, and cost compared with the ones formed by other methods. The EVP-HPDC process paves the way for the large-scale application of BMGs.

Texto completo da fonteResumo:
This paper presents a new framework for elastic viscoplastic (EVP) constitutive modelling. In developing the model, a general one-dimensional elastic viscoplastic (1D EVP) relationship is first derived for isotropic stressing conditions using an "equivalent-time" concept. This 1D EVP model is then generalized into a three-dimensional EVP model based on Modified Cam-Clay and viscoplasticity. Fitting functions are proposed for fitting data when model parameters are being determined. Using these functions, a specific EVP model is developed which describes the time-dependent stress-strain behaviour of soils under triaxial stress states. This model has been calibrated using data from a densely compacted sand-bentonite mixture. The calibrated model is used to compute time-dependent (or strain rate dependent) stress-strain curves from a multistage shear creep test and a step-changed, constant strain rate undrained triaxial compression test. Predictions from the EVP model are in general agreement with measured values. It is demonstrated that the model can simulate accelerating creep when deviator stresses are close to the shear strength envelope in a q creep test. It can also model the behaviour in unloading-reloading and relaxation. Limitations and possible improvements are also indicated.Key words: equivalent time, stress-strain, time dependent, elastic, viscoplastic, triaxial.

Organisations continuously seek opportunities to be more productive through the human capital they employ. A firm offering of the employee value proposition (EVP) and understanding of employee commitment could enable organisations to have committed employees that enjoy their work and are oriented towards a growth trajectory. This study sought to examine the effect of the EVP on normative commitment in a parastatal organisation. A quantitative research approach was selected to explore the research objectives. The research instruments comprised of value attributes scale and normative commitment scale. The population sample consisted of employees (N=251). Convenience sampling was used within the context of the study. Descriptive statistics, Factory analysis, Pearson correlation analysis, and Regression analysis were employed to interpret data collected and address the research objectives. A positive relationship between the variables was established. The three EVP factors (work, rewards, and opportunity) positively correlate with normative commitment. Recommendations are made to managers and HR Practitioners regarding the EVP and normative commitment of parastatal employees, which have the potential to employee commitment when implemented. The study provided insights on the factors, affecting EVP and normative commitment. The study also showed the relationship between the variables, enabling management, and HR practitioners to implement strategic interventions to influence employees' normative commitment and EVP experience.

Purpose Based on attribute research in marketing, importance-performance analysis (IPA) provides a useful analogy to examine employer branding concepts. The purpose of this paper is to use IPA to evaluate employees’ perceptions of important employer value proposition (EVP) attributes and their corresponding psychological contract fulfillment scores. IPA is applied to 40 EVP attributes and their corresponding EVP dimensions – “Economic Value”, “Development Value”, “Social Value”, “Work Value” and “Employer Reputation.” Further, the paper examines the difference between highly engaged and less engaged employees in their relationship to importance and fulfillment of the five EVP dimensions. Design/methodology/approach Data were drawn from information technology-business process management employees (n=520) in India through a questionnaire survey. The IPA matrix was used to plot the importance and fulfillment scores. Independent samples t-test was used to assess the difference between high and low engagement scores. Findings The results indicate that several EVP attributes fall within the “Concentrate Here” quadrant that requires more focus. With respect to EVP dimensions, social value needs focus; economic value received “Low Priority”; and work value and employer reputation are identified as “Potential Overkill.” The findings also suggest that, organizations should engage employees across all dimensions, by both prioritizing and fulfilling their obligations promptly. Practical implications The study highlights the need for HR practitioners and academicians to draw insights from attribute research in marketing to effectively devise the employer branding strategy of individual organizations. Originality/value This paper is the first of its kind to apply IPA to EVP attributes, which contributes to the growing literature on employer branding.

<p>Los espacios verdes públicos (EVP) son elementos fundamentales de sostenibilidad urbana. No obstante, su gestión y mantenimiento requieren de elevada capacidad institucional. Puntualmente, en el Área Metropolitana de Neuquén (AMN) han surgido estrategias innovadoras en materia de EVP a través de la consolidación de frentes fluviales. El objetivo de este trabajo es caracterizar espacios verdes públicos del frente fluvial del río Limay en las ciudades de Neuquén y Plottier, para el establecimiento de relaciones entre la gestión local y la calidad física de los EVP. Para tal fin se aplicó un análisis multidimensional en torno a cuatro variables de interés: programas de renovación urbana costera vigentes; ordenamiento territorial ambiental (OTA); grado de complejidad urbana del EVP y su calidad. Se hallaron diferencias entre las localidades en relación con los programas urbanos vigentes y con el OTA de los espacios costeros. Estas divergencias se reflejan en el nivel de planificación interna de los EVP y su calidad física en función de las variables de análisis abordadas. A partir de las conclusiones del estudio, surgen algunos aspectos a considerar: i) la gestión de los EVP requiere una labor institucional multiescalar; ii) es positivo que la creación de EVP se enmarquen en proyectos urbanos que se consoliden en ordenanzas de OTA; iii) se precisan mecanismos que regulen el cumplimento de lo dispuesto en las ordenanzas vigentes; iv) el aprovechamiento de espacios costeros para recreación debe acompañarse de sensibilización y educación ambiental activa a sus usuarios.</p>

PurposeThis study investigates the relationship between buyer-supplier top management team (TMT) demographic misalignment (defined as differences in TMT composition based on background, age and gender) and environmental performance (EVP).Design/methodology/approachThe empirical setting is publicly held US manufacturing firms that are present in both the Kinder, Lydenberg and Domini’s (KLD's) annual EVP ratings and Bloomberg's supply chain database. The study employs panel data regression methods on an unbalanced panel dataset of 7,493 dyad-year observations comprising 427 unique firms.FindingsThe research shows that misalignment in functional background and gender composition between TMTs have a negative outcome on both the buyer's and the suppliers' EVP. However, increasing presence of females across TMTs has a positive influence on EVP. Further, the research shows that misalignment based on age between the TMTs does not impact EVP in any significant way. On the contrary, increasing age across TMTs is a significant predictor of EVP.Originality/valueThis study builds on existing works in TMT heterogeneity and adds context to the heightening belief in the positive linkage between heterogeneity and performance through extension to a boundary spanning interfirm context.

Purpose This study aims to expand the emerging body of literature on employer branding from the current employee perspective. It proposes that effective integrated communication helps an organization fulfill its employer value proposition or employment value proposition (EVP). A firm that fulfills its brand promise in terms of EVP will derive employee-based brand equity (EBBE) benefits. Integrated communication is effective when employees experience coordination and consistency in brand communication. This influences their perception of psychological contract fulfillment (in terms of EVP attributes), which results in positive employee behavior in the form of EBBE benefits. Design/methodology/approach The study draws insights from the signaling theory and psychological contract literature which is based on the social exchange theory. The literature on integrated communication, employer branding and internal branding was reviewed to propose the relationships between the variables of interest. Data was collected using a questionnaire survey on 520 employees from the information technology (IT)-business process management industry in India, which is a customer-oriented industry known for its exemplary employer practices. Findings The findings suggest that integrated communication effectiveness impacts the perceived fulfillment of EVP attributes and EBBE. Again, the fulfillment of the relational value dimension of EVP attributes partially mediates the relationship between integrated communication effectiveness and EBBE. Originality/value This study is one of the first to explore employees’ perception of integrated communication effectiveness and fulfillment in terms of EVP attributes as antecedents to EBBE.

As an effective way for controlling emission of nitrogen oxide, EGR (Exhaust Gas Recirculation) has been widely used in automobiles. EVP (EGR valve position sensor) is a key component in EGR and functions as obtaining the accurate EGR valve opening position for governing the recirculation volume of exhaust gas. Its overall quality and working accuracy affect the performance of EGR directly and must be detected stringently before delivered from the factory. To solve the problems of labor intensity, low detecting efficiency, big deviation results with traditional EVP manual detection equipment in an automotive electronics company, an automatic detection system for EVP is developed based on PLC and industrial microcomputer. The working principle and structure of the system and design of EVP detection fixture are present, and hardware and software of its control system are developed in the paper. Three function modules, that are manual operation, automatic operation and data statistical analysis, are described in more detail. The practical application shows that the automatic detection system for EVP can achieve detection process flexibility, increase detection efficiency and accuracy greatly and solve the problems with traditional method effectively.

Abstract. The Finite-Element Sea Ice Model (FESIM), used as a component of the Finite-Element Sea ice Ocean Model, is presented.

The EVP part also includes a modified approach proposed recently by Bouillon et al. (2013), which is characterized by an improved stability compared to the standard EVP approach. The model is formulated on unstructured triangular meshes. It assumes a collocated placement of ice velocities, mean thicknesses and concentration at mesh vertices, and relies on piecewise-linear (P1) continuous elements. Simple tests for the modified EVP and VP solvers are presented to show that they may produce very close results provided the number of iterations is sufficiently high.

In this work, we investigate the modular version of the Ekeland variational principle (EVP) in the context of variable exponent sequence spaces ℓ p ( · ) . The core obstacle in the development of a modular version of the EVP is the failure of the triangle inequality for the module. It is the lack of this inequality, which is indispensable in the establishment of the classical EVP, that has hitherto prevented a successful treatment of the modular case. As an application, we establish a modular version of Caristi’s fixed point theorem in ℓ p ( · ) .

Abstract Human use of marine and coastal areas is increasing worldwide, resulting in conflicts between different interests for marine space, overexploitation of marine resources, and environmental degradation. In this study we developed a methodology that combines assessments of marine environmental vulnerability and cumulative human pressures to support the processes of ecosystem-based adaptive maritime spatial planning. The methodology is built on the spatially explicit marine environmental vulnerability profile (EVP) that is an aggregated product of the distribution of essential nature values (habitat-forming benthic macroalgal and invertebrate species, benthic species richness, birds and seals as top marine predators) and their sensitivities to disturbances. The marine environmental cumulative risk profile (ERP) combines the EVP and the HELCOM Baltic Sea Pressure Index (BSPI), the latter representing the spatial distribution of intensities of cumulative anthropogenic pressures. The ERP identifies areas where environmental risks are the highest due to both long recoveries of the biota and high intensities of human pressures. This methodology can be used in any other sea areas by modifying the list of nature values, their sensitivity to disturbances, and the intensities of human pressure.

Texto completo da fonteResumo:
Polishing, the last manufacturing procedure in the process of optics manufacturing, has been restricted by the existed contradictory propositions of efficiency and accuracy. As a result, a variety of new combined processing techniques put forward by researchers in many countries. While, elliptical vibration polishing (short as EVP) well considers efficiency and accuracy in machining. This paper focuses on the kinematics research of EVP tools, and proves the superiority of EVP through the vibration parameter optimization. Perfect tool path gets by the impact analysis of phase difference, frequency ratio and amplitude of the polishing tool. Meanwhile the optimum frequency for EVP is studied from the cost and efficiency perspective. The simulations reveal that the perfect tool path will be obtained in the following situations: phase difference at 90°, frequency ratio at 0.909, adjusts the tool vibration amplitude in consideration of minimum curvature radius in polishing area, and appropriately select the vibration frequency.

Texto completo da fonteResumo:
The use of electronic vapour products (EVPs) continues to increase worldwide and with advances in cell culture systems, molecular biology and the computational sciences there is also accumulating evidence of their potential reduced toxicity and reduced potential harm when compared to cigarette smoke. To further understand the potential risks and health effects associated with exposure to EVP aerosols we have assessed the cellular and transcriptomic response from a commercially available lung tissue culture system (MucilAirTM) following a single sub-cytotoxic exposure to cigarette smoke and the equivalent nicotine delivered dose of EVP aerosol. The transcriptomic, cellular (cilia beat frequency (CBF) and percent active area (%AA), trans epithelial electrical resistance (TEER), histology) and cytokine release were assessed at 4- and 48- hours following recovery from air, EVP aerosol (8.4% V/V: mybluTM blueberry flavour, 2.4% nicotine) and 3R4F smoke (3.5% V/V: exposure). No pathological changes were observed at either recovery time point from any exposure. Air and EVP aerosol exposure had no effect on CBF, %AA nor TEER at 48 hours. Exposure to cigarette smoke resulted in a decrease in TEER, an increase in CBF and the release of proinflammatory cytokines at both recovery time points. Although the number of significantly expressed genes was minimal following exposure to EVP aerosol, exposure to 3R4F smoke resulted in a significant upregulation of several disease relevant pathways. These data provide evidence that following an acute exposure to EVP aerosol there is significantly less damage to lung cells in culture than the equivalent, nicotine based, dose of cigarette smoke.

Texto completo da fonteResumo:
Research gaps exist in toxic metals characterization in e-cigarette, or vaping, products (EVPs) as these analytes typically have low concentrations and most standard aerosol trapping techniques have high metals background. An additional complication arises from differences in the EVP liquid formulations with nicotine products having polar properties and non-nicotine products often being non-polar. Differences in polar and non-polar matrices and the subsequent aerosol chemistries from various EVPs required modifications of our previously reported nicotine-based EVP aerosol method. Validation and application of the expanded method, suitable for both hydrophobic and hydrophilic aerosols, are reported here. The metals analyzed for this study were Al, Cr, Fe, Co, Ni, Cu, Cd, Sn, Ba, and Pb. The method limits of detection for the modified method ranged from 0.120 ng/10 puffs for Cd to 29.3 ng/10 puffs for Al and were higher than reported for the previous method. Results of the analyses for metals in aerosols obtained from 50 EVP products are reported. Cannabinoid based EVP aerosols were below reportable levels, except for one sample with 16.08 ng/10 puffs for Cu. Nicotine-based EVP results ranged from 6.72 ng/10 puffs for Pb to 203 ng/10 puffs for Sn. Results of the analyses for these metals showed that aerosols from only 5 of the 50 devices tested had detectable metal concentrations. Concentrations of toxic elements in the aerosols for nicotine-based EVP aerosol metal concentration ranges were consistent with previously published results of aerosol analyses from this class of devices.

Texto completo da fonteResumo:
This paper presents modelling of the consolidation of foundation soil under a wide embankment constructed over soft soil. An elastic–viscoplastic (EVP) constitutive model is used to represent the foundation soil for the coupled finite element analysis (FEA). A unit-cell analysis is carried out to capture the maximum settlement and the development of excess pore-water pressure with time below the centreline of the embankment for a long period (9 years). A new function for capturing the varying nature of the creep or secondary compression coefficient is proposed and used in association with the EVP model. The input material parameters for this study were determined from extensive laboratory experiments except for the equivalent horizontal permeability, which was systematically estimated by using vertical permeability data obtained from one-dimensional consolidation tests and by back-analysing the first 12 months of field settlement data. Comparisons are made among the predictions obtained adopting an elastoplastic modified Cam clay model and the EVP model with constant and varying creep coefficients for the foundation soil and the corresponding field data. The predictions with the EVP model are found to be better than those with the elastoplastic model and the use of a varying creep coefficient for the EVP model seems to further improve its predicting ability.

Texto completo da fonteResumo:
Muscle atrophy, a reduction of muscle mass, strength, and volume, results from reduced muscle use and plays a key role in various muscular diseases. In the microgravity environment of space especially, muscle atrophy is induced by muscle inactivity. Exposure to microgravity induces muscle atrophy through several biological effects, including associations with reactive oxygen species (ROS). This study used 3D-clinostat to investigate muscle atrophy caused by oxidative stressin vitro, and sciatic denervation was used to investigate muscle atrophyin vivo. We assessed the effect ofOenothera odorataroot extract (EVP) on muscle atrophy. EVP helped recover cell viability in C2C12 myoblasts exposed to microgravity for 24 h and delayed muscle atrophy in sciatic denervated mice. However, the expressions of HSP70, SOD1, and ceramide in microgravity-exposed C2C12 myoblasts and in sciatic denervated mice were either decreased or completely inhibited. These results suggested that EVP can be expected to have a positive effect on muscle atrophy by disuse and microgravity. In addition, EVP helped characterize the antioxidant function in muscle atrophy.

El artículo propone un análisis de la proximidad de la población adulta mayor a los espacios verdes públicos (EVP) de los municipios de Santa Fe y Rafaela (Argentina), con el objetivo de dimensionar qué tan próximos se ubican los EVP para los adultos mayores, e identificar en qué zonas urbanas están los déficits según los parámetros internacionales. El propósito es generar aportes en esta materia que puedan ser de utilidad para los planes urbanos, en dichas aglomeraciones de tamaño intermedio (ATI). La metodología se sustenta en datos del Censo Nacional de Población, Hogares y Viviendas (INDEC, 2010) y en relevamientos realizados por medios propios a partir de cartografías municipales. El estudio integra los EVP identificados en una matriz de datos espacial que posibilita cuantificar el área verde disponible, así como cartografiar e identificar las zonas urbanas desprovistas de estos espacios, a partir del trazado de un ‘área óptima de proximidad’, sugerida por la OMS. Los principales resultados señalan, respecto de la cantidad de área verde por habitante, que ambos centros urbanos se encuentran dentro de los estándares recomendados por la OMS, aunque la participación de los distintos EVP según ‘rangos de tamaño’ indica un predominio general de pequeños espacios, con escasa contribución en la superficie verde total. Por otra parte, los municipios analizados presentan una desigual proporción de adultos mayores residiendo dentro del ‘área óptima de proximidad’ a los EVP.

Ellagic acid (EA), a natural polyphenol found in berries, has high antioxidant capacity. This study aimed to improve EA solubility by complex formation with urea (UR) using solvent an evaporation method and evaluate its solubility, antioxidant capacity, and physical properties. The solubility test (25 °C, 72 h) showed that the solubility of EVP (EA/UR = 1/1) was approximately two-fold higher than that of EA (7.13 µg/mL versus 3.99 µg/mL). Moreover, the IC50 values of EA and EVP (EA/UR = 1/1) (1.50 µg/mL and 1.30 µg/mL, respectively) showed higher antioxidant capacity of EVP than that of EA. DSC analysis revealed that the UR peak at 134 °C disappeared, and a new endothermic peak was observed at approximately 250 °C for EVP (EA/UR = 1/1). PXRD measurements showed that the characteristic peaks of EA at 2θ = 12.0° and 28.0° and of UR at 2θ = 22.0°, 24.3°, and 29.1° disappeared and that new peaks were identified at 2θ = 10.6°, 18.7°, and 26.8° for EVP (EA/UR = 1/1). According to 2D NOESY NMR spectroscopy, cross-peaks were observed between the -NH and -OH groups, suggesting intermolecular interactions between EA and UR. Therefore, complexation was confirmed in EA/UR = 1/1 prepared by solvent evaporation, suggesting that it contributed to the improvement in solubility and antioxidant capacity of EA.

E-vapor products (EVP) have become popular alternatives for cigarette smokers who would otherwise continue to smoke. EVP research is challenging and complex, mostly because of the numerous and rapidly evolving technologies and designs as well as the multiplicity of e-liquid flavors and solvents available on the market. There is an urgent need to standardize all stages of EVP assessment, from the production of a reference product to e-vapor generation methods and from physicochemical characterization methods to nonclinical and clinical exposure studies. The objective of this review is to provide a detailed description of selected experimental setups and methods for EVP aerosol generation and collection and exposure systems for their in vitro and in vivo assessment. The focus is on the specificities of the product that constitute challenges and require development of ad hoc assessment frameworks, equipment, and methods. In so doing, this review aims to support further studies, objective evaluation, comparison, and verification of existing evidence, and, ultimately, formulation of standardized methods for testing EVPs.

Texto completo da fonteResumo:
This paper presents a new three-dimensional elastic viscoplastic (3D EVP) constitutive model for the time-dependent stressstrain behaviour of both normally consolidated and overconsolidated clays. There are two major new developments in the 3D EVP model: (i) incorporation of a nonlinear creep function with a limit for the creep volume strain under isotropic stressing conditions; (ii) adoption of a new loading surface function with a smooth shape on the π plane. Based on the "equivalent time" concept of Yin and Graham, the formulation of the new 3D EVP model is derived using the new nonlinear creep function and loading surface function. A new approach to determining all model parameters is presented. The 3D EVP model is calibrated using data from one conventional isotropic stress creep test and consolidated-undrained triaxial tests on soft Hong Kong marine deposits (HKMD). The model is verified by comparing model results with those from both normally and overconsolidated triaxial tests on HKMD and a mixture of kaolin and bentonite.Key words: creep, time-dependent, viscoplastic, equivalent time, stressstrain, constitutive model, verification, clay.

Respondents were shown product images and asked about ever use, current (past 30 days) use and reasons for use. Weighted point estimates and adjusted ORs were assessed.ResultsIn 2018, 7.9% of participants had ever used flash drive-shaped EVPs, including 25.7% of current cigarette smokers and 45.9% of current EVP users. Moreover, 2.0% reported current use, including 6.8% of cigarette smokers and 34.3% of EVP users. Leading reasons for ever use were ‘to deliver nicotine’ (30.7%) and ‘friend or family member used them’ (30.2%).ConclusionsAbout one in 13 US adults have ever used flash drive-shaped EVPs, with use being highest among current EVP users. Nicotine content and friend/family use are drivers of ever use.Public health implicationsUnderstanding use of emerging EVP types can inform strategies to maximise any potential benefits for adult cessation and minimise risks of youth initiation.

Background: Factors that are known to cause lumbar epidural venous plexus (EVP) engorgement include inferior vena cava (IVC) obstruction, portal hypertension, vascular agenesis, morbid obesity, and/or hypercoagulable states. Here, we present a 32-year-old female admitted with the new onset of lumbar radiculopathy attributed to a gastric balloon causing compression of the IVC and engorgement of the EVP. Case Description: A 32-year-old female was admitted with a left L5 radiculopathy. She had a history of morbid obesity and had undergone intragastric balloon insertion 4 months ago. The abdominal/pelvic CT documented an intragastric balloon producing a voluminous gastric mass with resultant compression of the IVC. The lumbar MRI showed the resultant marked multilevel engorgement of the lumbar EVP. Here, following balloon removal, the patient was immediately symptom free and remained asymptomatic over the next postoperative year. Conclusion: An intragastric balloon can produce a voluminous gastric mass that can result in IVC occlusion and engorgement of the EVP, leading to lumbar radiculopathy. Removal of the balloon results in immediate and permanent resolution of the compressive symptoms.

Purpose Velopharyngeal (VP) ratios are commonly used to study normal VP anatomy and normal VP function. An effective VP (EVP) ratio may be a more appropriate indicator of normal parameters for speech. The aims of this study are to examine if the VP ratio is preserved across the age span or if it varies with changes in the VP portal and to analyze if the EVP ratio is more stable across the age span. Method Magnetic resonance imaging was used to analyze VP variables of 270 participants. For statistical analysis, the participants were divided into the following groups based on age: infants, children, adolescents, and adults. Analyses of variance and a Games–Howell post hoc test were used to compare variables between groups. Results There was a statistically significant difference ( p < .05) in all measurements between the age groups. Pairwise comparisons reported statistically significant adjacent group differences ( p < .05) for velar length, VP ratio, effective velar length, adenoid depth, and pharyngeal depth. No statistically significant differences between adjacent age groups were reported for the EVP ratio. Conclusions Results from this study report the EVP ratio was not statistically significant between adjacent age groups, whereas the VP ratio was statistically significant between adjacent age groups. This study suggests that the EVP ratio is more correlated to VP function than the VP ratio and provides a more stable and consistent ratio of VP function across the age span.

Objectives External valvuloplasty (eVP) is a reconstructive surgical method to repair the function of the terminal and preterminal valves. We evaluated the 6-month outcomes of eVP regarding the diameter of the great saphenous vein (GSV). Methods Patients from five vein centres were included in this observational study. Follow-up involved detailed duplex sonography of the GSV. The venous clinical severity score (VCSS) and the C class of the clinical, aetiologic, anatomic and pathophysiologic (CEAP) classification were recorded. Results We enrolled 210 patients, with a follow-up rate of 58%; eVP was sufficient in 95.24% of the patients. The GSV diameters decreased significantly from 4.4 mm (standard deviation (SD): 1.39) to 3.9 (SD: 1.12), 4 cm distal to the saphenofemoral junction (SFJ); from 3.7 mm (SD: 1.10) to 3.5 mm (SD: 1.02) at the mid-thigh; from 3.6 mm (SD: 1.14) to 3.3 mm (SD: 0.94) at the knee and from 3.1 mm (SD: 0.99) to 2.9 mm (SD: 0.78) at the mid-calf. VCSS decreased significantly from 4.76 (SD: 2.13) preoperatively to 1.77 (SD: 1.57) 6 months postoperatively. Conclusions GSV function can be restored by eVP; diameters over the total length of the GSV decreased significantly.

Abstract The most important ecosystem service for sustainable crop production is pollination, the mutualistic interaction between plants and animals. Honeybees are being indispensable role in this process. The total economic value of crop pollination worldwide has been estimated at €153 billion annually. Animal pollination of agricultural crops is provided by both managed and wild pollinators. The aim of this study was to determine the economic value of pollination services and vulnerability of Ethiopian agriculture in the face of pollinator decline. An improved approach to determine the economic value of pollination (EVP) services is applied to multiply a crop’s total value by a coefficient between zero and one representing the crop’s dependency on pollination services for production. The potential production value loss due to lack of pollinators is also computed as the ratio of EVP to economic production value. Then EVP was $ 815.2 million dollars and vulnerability of Ethiopian agriculture due to lack of pollinators 16% in the 2015/16 crop production season. The regional state of Oromia benefited the most followed by the regional states of Amhara and South Nation Nationality People (SNPP). Coffee, the leading crop, has the highest EVP in the country followed by Faba beans and Nug (Guizotia abyssinica). Ethiopia has highly benefited from biological pollinators, so protecting them has significant role in the country’s economy. Most crops in Ethiopia have no pollination dependency ratio and some minor crop has no production data, incorporating them possible to better estimation of EVP service for the future.

In this paper, we develop an elasto-viscoplastic (EVP) model for clay using the non-associated flow rule. This is accomplished by using a modified form of the Perzyna’s overstressed EVP theory, the critical state soil mechanics, and the multi-surface theory. The new model includes six parameters, five of which are identical to those in the critical state soil mechanics model. The other parameter is the generalized nonlinear secondary compression index. The EVP model was implemented in a nonlinear coupled consolidated code using a finite-element numerical algorithm (AFENA). We then tested the model for different clays, such as the Osaka clay, the San Francisco Bay Mud clay, the Kaolin clay, and the Hong Kong Marine Deposit clay. The numerical results show good agreement with the experimental data.

In this paper, we give a graphical version of the Ekeland’s variational principle (EVP) for equilibrium problems on weighted graphs. This version generalizes and includes other equilibrium types of EVP such as optimization, saddle point, fixed point and variational inequality ones. We also weaken the conditions on the class of bifunctions for which the variational principle holds by replacing the strong triangle inequality property by a below approximation of the bifunctions.

Abstract. Non-structural carbohydrates (NSC) play a central role in the construction and maintenance of a tree's vascular system, but feedbacks between the NSC status of trees and wood formation are not fully understood. We aimed to evaluate multiple dependencies among wood anatomy, winter NSC, and phenology for coexisting temperate (Quercus robur) and sub-Mediterranean (Q. pyrenaica) oaks along a water-availability gradient in the NW Iberian Peninsula. Sapwood NSC concentrations were quantified at three sites in December 2012 (N = 240). Leaf phenology and wood anatomy were surveyed in 2013. Structural equation modelling was used to analyse the interplay among hydraulic diameter (Dh), winter NSC, budburst date, and earlywood vessel production (EVP), while the effect of Dh and EVP on latewood width was assessed by using a mixed-effects model. NSC and wood production increased under drier conditions for both species. Q. robur showed a narrower Dh and lower soluble sugar (SS) concentration (3.88–5.08 % dry matter) than Q. pyrenaica (4.06–5.57 % dry matter), but Q. robur exhibited larger EVP and wider latewood (1403 µm) than Q. pyrenaica (667 µm). Stem diameter and Dh had a positive effect on SS concentrations, which were related to an earlier leaf flushing in both species. Sapwood sugar content appeared to limit EVP exclusively in Q. pyrenaica. In turn, Dh and EVP were found to be key predictors of latewood growth. Our results confirm that sapwood SS concentrations are involved in modulating growth resumption and xylem production in spring. Q. pyrenaica exhibited a tighter control of carbohydrate allocation to wood formation than Q. robur, which would play a role in protecting against environmental stress in the sub-Mediterranean area.

Context: Current smartphone models have a very interesting set of sensors such as cameras, IMUs, GPS, and environmental variables. This combination of sensors motivates the use of smartphones in scientific and service applications. One of these applications is precision agriculture, specifically drone position estimation using computer vision in GPS-denied environments for remote crop measurements. Method: This work presents the development of EVP, a vision-based position estimation system using a modern smartphone and computer vision methods. EVP consists of two software applications: an Android app (mobile station) running on a smartphone capable of controlling the drone’s flight, acquiring images, and transmitting them through a wireless network; and another application (base station) running on a Linux-based computer capable of receiving the images, processing them and running the position estimation algorithms using the acquired images. In this work, the mobile station is placed in a quadcopter. Using EVP, users can configure the mobile and base station software, execute the vision-based position estimation method, observe position graph results on the base station, and store sensor data in a database. Results: EVP was tested in three field tests: an indoor environment, an open field flight, and a field test over the Engineering Department’s square at Universidad del Valle. The root mean square errors obtained in XY were 0,166 m, 2,8 m, and 1,4 m, respectively, and they were compared against the GPS-RTK measurements. Conclusions: As a result, a vision-based position estimation system called EVP was developed and tested in realworld experiments. This system can be used in GPS-denied environments to perform tasks such as 3D mapping, pick-up and delivery of goods, object tracking, among others.

Introduction. Pseudoexfoliation syndrome (PEX) is a relatively widespread generalized age-related disease, in which abnormal fibrillar extracellular material is produced and accumulates in many tissues including vessels. Glaucoma occurs more commonly in eyes with PEX than in those without it. Episcleral venous pressure (EVP) is an important determinant of intraocular pressure (IOP). It seems reasonable to evaluate episcleral venous pressure in patients with PEX. Purpose. To evaluate episcleral venous pressure in patients with PEX. Methods. 540 eyes of 270 patients were enrolled in the prospective study. We evaluated episcleral venous pressure. Results. EVP in total vein compression in lower-nasal quadrant (mmHg) in main group(with PEX) was 14.0±3.29, in control group No. 1 (non PEX, adults) - 14.38±3.77, in control group No. 2 (non PEX, young) - 10.91±2.34. EVP in total vein compression in lower-temporal quadrant (mmHg) in main group was 15.1±3.31, in control group No. 1 - 15.76±3.45, in control group No. 2 - 11.00±2.16. Difference in episcleral venous pressure between main group and age-matched control group No. 1 was not significant, and between main group and control group No. 2 was significant. Conclusion. EVP level is not influenced by PEX, but is influenced by age.

Abstract Introduction Real-world evidence regarding likely long-term health effects of e-vapor products (EVP) under actual use conditions relative to cigarette smoking is not well studied. Methods In this cross-sectional, observational study, biomarkers of exposure (BOE) to select harmful and potentially harmful constituents and biomarkers of potential harm (BOPH) relevant to smoking-related diseases were measured in exclusive adult EVP users (AEVP, n = 144) and exclusive adult cigarette smokers (AS, n = 73). AEVP used their own brand of EVP for 6+ months following 10+ years of cigarette smoking and AS smoked own brand of cigarettes for 10+ years. Subject recruitment and informed consent were obtained online and urine/blood samples were collected at local clinical laboratories, representing a new paradigm for collecting real-world evidence. Results The levels of total NNAL (NNK metabolite), 3-hydroxypropyl mercapturic acid (acrolein metabolite), and carboxyhemoglobin (carbon monoxide measure) were 46% to 86% lower in AEVP compared with AS (p ≤ .0001) as was nicotine equivalents (nicotine and its five metabolites; 36%, p < .01). The levels of some BOPH were significantly lower in AEVP compared with AS for 11-dehydrothromboxane-B2 (29%, p = .04; platelet activation), 8-epi-prostaglandin F2α (23%, p = .02; oxidative stress) and soluble intercellular adhesion molecule-1 (16%, p = .02; endothelial function). Conclusions This study demonstrates the feasibility of a new approach for collecting real-world evidence. Substantially lower levels of BOEs (NNK, nicotine, acrolein, carbon monoxide) and favorable differences in BOPHs (platelet activation, oxidative stress, endothelial function) suggest EVP users may have lower health risks than cigarette smokers. Implications Cigarette smoking causes serious diseases. Switching from a combustible tobacco product to a noncombustible product is a potential harm reduction pathway for adult smokers unable or unwilling to quit. Real-world evidence regarding the relative risk of EVP use compared with cigarettes is not well established. This study provides data specific to BOE to tobacco smoke constituents and biomarkers of potential harm collected under actual use conditions in a real-world setting. The totality of evidence suggests that exclusive EVP use may present lower health risk compared with smoking cigarettes.

The use of electronic vapor products (EVPs) has increased dramatically in the past decade. The objectives of our study were to examine the frequency of EVP use; to identify demographic characteristics, risk-taking behaviors, and beliefs about vaping; and to determine symptoms associated with EVPs among adolescents. A questionnaire addressing these objectives was administered to a convenience sample of subjects aged 12 to 23 years. Among 494 completed questionnaires, 80% of responders were considered experimenters/nonusers (never tried or tried one time) and 20% were considered frequent users (at least once a month). We identified demographic features and risk-taking behaviors associated with EVP use. In the previous 6 months, frequent users were more likely to report headache, cough, sleep disturbances, dehydration, weakness, racing heart, chest pain, and tremors. Our findings provide evidence to support efforts to decrease EVP use through screening, education, and preventative strategies.

ABSTRACT Edwardsiella tarda is a gram-negative enteric pathogen that causes hemorrhagic septicemia in fish and gastro- and extraintestinal infections in humans. A type III secretion system (TTSS) and a putative secretion system (EVP) have been found to play important roles in E. tarda pathogenesis. Our previous studies suggested that the TTSS and EVP gene clusters were regulated by a two-component system of EsrA-EsrB. In the present study, we characterized another regulator, EsrC, which showed significant sequence similarity to the AraC family of transcriptional regulators. Mutants with in-frame deletions of esrC increased the 50% lethal doses in blue gourami fish, reduced extracellular protein production, and failed to aggregate. Complementation of esrC restored these three phenotypes. Two-dimensional gel electrophoresis showed that EsrC regulated the expression of secreted proteins encoded by the TTSS (such as EseB and EseD) and EVP (EvpC) gene clusters. The expression of esrC required a functional two-component system of EsrA-EsrB. EsrC in turn regulated the expression of selected genes encoded in TTSS (such as the transcriptional unit of orf29and orf30, but not esaC) and genes encoded in the EVP gene cluster. The present study sheds light on the regulation of these two key virulence-associated secretion systems and provides greater insight into the pathogenic mechanisms of this bacterium.
