CO2 and H2S Degassing at Fangaia Mud Pool, Solfatara, Campi Flegrei (Italy): Origin and Dynamics of the Pool Basin

The Fangaia mud pool provides a “window” into the hydrothermal system underlying the degassing Solfatara crater, which is the most active volcanic centre inside the restless Campi Flegrei caldera, Southern Italy. The present study aimed at unravelling the degassing dynamics of CO2 and H2S flushing through the pH 1.2 steam-heated Fangaia mud pool, an ideal field laboratory as a proxy of an active crater lake. Our results from MultiGAS measurements above Fangaia’s surface show that H2S scrubbing, demonstrated by high CO2/H2S ratios, was most efficient in the portions of the basin affected by diffusive degassing. Convective bubbling degassing instead was the most effective mechanism to release gas in quantitative terms, with lower CO2/H2S ratios, similar to the Solfatara crater fumaroles, the high-T end member of the hydrothermal system. Unsurprisingly, total estimated CO2 and H2S fluxes from the small Fangaia pool (~184 m2 in June 2017) were at least two orders of magnitude lower (CO2 flux < 64 t/d, H2S flux < 0.5 t/d) than the total CO2 flux of the Campi Flegrei caldera (up to 3000 t/d for CO2), too low to affect the gas budget for the caldera, and hence volcano monitoring routines. Given the role of the rising gas as “sediment stirrer”, the physical and chemical processes behind gas migration through a mud pool are arguably the creating processes giving origin to Fangaia. Follow-up studies of this so far unique campaign will help to better understand the fast dynamics of this peculiar degassing feature.
SPATIAL DEPENDENCE AND RELATIONSHIPS OF ELECTRICAL CONDUCTIVITY TO SOIL ORGANIC MATTER, PHOSPHORUS, AND POTASSIUM

Apparent electrical conductivity (ECa) can be an indirect indicator of soil nutrient concentrations, and strong relationships between ECa and nutrients may help delineate fertility management zones. The objectives of this study were to determine the relationships among ECa, organic matter (OM), P, and K and to assess the spatial dependency and correlation components of such relationships. Spatial correlations and relationships of ECa with OM, P, and K were determined using geostatistical and regression analyses. ECa was measured in parallel transects 4.6 m apart in adjacent Indiana (United States) fields with multiple soil series in 2001, 2002, and 2003. Electrical conductivity, OM, P and K were strongly spatially dependent. Spatial correlations between ECa and these variables were cyclic: positive at distances of <40 m, but negative at distances <70 m. Organic matter, P, and K showed relatively low but significant correlations with ECa in all the 3 years of study. Maximum correlations were obtained with OM, P, and K (r = 0.55, 0.50, 0.53, respectively) when soil moisture content was relatively higher in 2003. Data separation by soil series improved correlations between ECa and soil chemical attributes when the soil was a Mollisol, but not for an Alfisol. Regression models showed that ECa was significantly related to the variables but that ECa failed to detect concentration changes and explained <7% of the variability of these nutrients. The results suggested that ECa has limited usefulness in estimating soil chemical properties or in defining possible management zones for OM, P, and K in these soils.
Teachers’ orientations to educational research and data in England and Australia: implications for teacher professionalism

ABSTRACT Teachers’ engagement with and understanding of educational research and data is an increasing concern for policy-makers around the globe. With unprecedented access to, and new forms of, ‘data’ in schools, concerns for its ‘best practice’ use in classroom decision-making have come to the fore. In academic spaces, these developments have also been of concern due to what such pushes for ‘evidence-based practice’ may elide in terms of teacher knowledge and professionalism. In this article, we present findings from two national contexts, England and Australia, in order to explore how teachers understand themselves and their work in relation to educational data and research. We find that, despite highly engaged samples across contexts who place considerable importance on such research and data, respondents do not report an equal sense of capacity across the various forms which they may take. Particular limitations are identified in relation to action research. We argue that these results have consequences for the development of a ‘mature’ profession that goes beyond performative forms of professionalism and towards those of a ‘research-rich’ culture of trust.
A chain is no stronger than its weakest link: Weathering resistance of water-based intumescent coatings for steel applications

A systematic approach was used to investigate the weathering-induced degradation of a common water–based intumescent coating. In this study, the coatings are intended for humid indoor applications on steel substrates. The coating contains ammonium polyphosphate, pentaerythritol, melamine, and polyvinyl acetate. By replacing each ingredient with a less water-soluble substance, the most vulnerable substances, polyvinyl acetate and pentaerythritol, were identified. Furthermore, the weathering resistance of the system was improved by exchanging the ingredients. The coatings were stressed by artificial weathering tests and evaluated by fire tests. Thermogravimetry and Fourier-transform infrared spectroscopy were used to study the thermal decomposition. This study lays the foundation for the development of a new generation of water-based intumescent coatings.
A New Approach in the Induction of Labor with Misoprostol Vaginal Insert in High-Risk Pregnancy Obese Women

Background and objectives: Induction of labor (IOL) is an event that occurs in up to onequarter of pregnancies; less is known about the outcomes and safety of IOL in obese pregnant woman; no data is available on misoprostol vaginal insert (MVI) IOL in high-risk pregnancy obese women. Objectives: (1) to evaluate the rate of successful IOL with 200 μg MVI in obese (Body Mass Index BMI over 30 kg/m2) high-risk pregnant women: late-term pregnancy, hypertension or diabetes, compared to obese non-high-risk ones; (2) to evaluate the safety profile of MVI in high-risk pregnancy obese patients. Study design: We conducted a cross-sectional study in "Filantropia" Clinical Hospital, Bucharest, Romania, from June 2017 to September 2019 (28 months). From a total of 11,096 registered live births, IOL was performed in 206 obese patients; 74 obese high-risk pregnant patients matched the inclusion criteria; of these, 33.8% pregnancies (n=25) were late-term (41 – 41+6 weeks), 43.2% (n=32) had associated pathologies (hypertension and diabetes); labor induction was guided using a standardized protocol. We evaluated the maternal and gestational age, parity, fetal tachysystole, hyper-stimulation, initial cervical status, time from induction to delivery, drug side effects, mode of delivery, and neonatal outcomes. Results: (a) The overall successful labor induction rate, evaluated by the vaginal delivery rate, was 71.6% (n=53), spontaneously or instrumentally assisted; 28.4% (n=21) births were unsuccessful MVI IOL, converted into caesareans. (b) No significant differences were found regarding the maternal outcomes; in terms of perinatal outcomes of safety, four cases of high-risk pregnancies vaginally delivered were associated with neonatal intensive care unit (NICU) admissions and a one-minute Apgar score under seven (5.4%). Most cases with adverse effects of misoprostol have been managed by vaginal delivery, except three cases of emergency Csection. Conclusions: Misoprostol vaginal insert is a safe choice in IOL in obese high-risk pregnancies with good maternal and perinatal outcomes.
Developing Competencies for Emotional, Instrumental, and Informational Student Support During the COVID-19 Pandemic: A Human Relations/Human Resource Development Approach

The Problem The COVID-19 pandemic required many college and university faculty members to transition quickly from traditional classroom instruction to virtual, online learning. Aside from mastering technical skills needed to maintain an uninterrupted learning environment, faculty were challenged with mastering social-emotional competencies for maintaining continuity in relationships (e.g. student/peer, student/instructor). This dilemma highlights transdisciplinary relationships between the fields of human relations (HRL) and human resource development (HRD). The Recommendation In this article, a framework is introduced and recommended for understanding the experiences of a university faculty member who, in addition to mastering technical competencies (e.g., coaching, care, collaboration), was also challenged with developing social-emotional support behaviors (e.g., emotional, instrumental, informational) while maintaining continuity in established relationships as a transdisciplinary HRL/HRD response to the pandemic. The Stakeholders This article offers faculty, higher education administrators, human relations professionals, and human resource development scholars/practitioners a model for ways in which to work professionally within the “new normal. ”
Prior Discipline and Performance among Police Officers: Does Organizational Fairness Matter?

Using a survey of police officers (n=1080) in a southern state of the USA, this study examines how overall performance is influenced by organizational fairness and prior disciplinary actions. In particular, this study focuses on the relationship between organizational treatment and officers’ self-acknowledged engagement in more innocuous forms of negative work-related behaviors, general task performance, and extra-role behaviors. Results suggest prior disciplinary actions and organizational treatment are related to officer performance. Our findings highlight fair treatment’s relationship to enhanced prosocial activities and reduced negative work behaviors. Of importance to police administrators, police officers’ fairness perceptions of the police organization appear to have a stronger influence on overall work performance among officers that have prior disciplinary actions, further underscoring the need for organizations to consider how officers are treated.
Discovering the Traits of Personality in Anesthesiologists at Different Stages of Emotional Burnout Syndrome

To date, intensive care medicine, anesthesiology, and resuscitation are medical spheres that deal with lifesaving issues, particularly the treatment of patients in critical or life-threatening situations. The profession of anesthesiologist-resuscitator is relatively new, although it has centuries-old prehistory. The study aims to identify personality traits that predispose to the formation of emotional burnout syndrome in anesthesiologists-resuscitators. The research was performed at the Anesthesiology and Resuscitation Departments of the regional healthcare facilities in Astana and Akmola cities. Findings obtained through this research confirm the hypothesis that personality traits in anesthesiologists-resuscitators are factors that facilitate the development of emotional burnout syndrome. Such a discovery necessitates the prevention of personality destructions as well as the establishment of conditions to reduce them in the case of occurrence. Proper arrangement of the work schedule and a favorable working environment allows preventing the emotional burnout among employees.
Size dependent thermodynamic properties of nanoparticles

Surface effect and crystal structure lead to formulating a theoretical model to study the influences of size on thermodynamic parameters, such as melting temperature, Debye temperature, melting entropy and specific heat capacity, of nanoparticles. The cohesive energy as a thermodynamic quantity was used to relate the ratio of surface area to volume of nanomaterial with thermodynamic properties which depend on size of the nanomaterial. In this contribution, Si and Au nanoparticles were considered to study due to their potential applications in science and technology. It was found that melting temperature, Debye temperature, melting entropy of nanoscale size material is decreased with decreasing the size up to their critical sizes. Whereas, the specific heat capacity tends to enhance with reduction in nanoparticle size. The present results for melting temperature, melting entropy and Debye temperature are compared with experimental and theoretical observations and adequate agreements are observed.
EFFECT OF CHLORIDE FERTILIZERS AND LIME ON WHEAT GRAIN YIELD AND TAKE-ALL DISEASE

One experiment was initiated in the fall of 1991 to evaluate the effect of chloride (Cl) fertilizers on the suppression of take-all disease (Gaeumannomyces graminis var. tritici Walker) in winter wheat (Triticum aestivum L.). Preplant and topdress rates of potassium chloride (KCl) and calcium chloride (CaCl2) (0, 34, 67 and 101 kg Cl ha−1) were applied each year. In 1995, plots were split in half whereby one half received 2.24 Mg of 76% ECCE lime ha−1 to elevate the pH and potentially increase disease incidence. Wheat grain yield was not affected by lime applications in any year (1995–1999). Plots exhibited visual symptoms of take-all in almost all years, however, grain yields increased in only two of eight years by the application of CaCl2 and KCl. Applied fertilizer Cl for take-all disease suppression was inconsistent, even following the application of lime where increased soil pH can increase disease severity.

Deep Thermohaline Circulation Across the Closure of the Central American Seaway

The closure of the Central American Seaway (CAS) resulted in changes of ocean‐climate dynamics since the late Miocene following the uplift of northern Andes. Reconstructing the bottom‐water temperatures (BWTs) of the Caribbean Sea illustrates feedbacks of the closure on the ocean‐climate system including deep‐water dynamics of the Caribbean Sea. Here, Mg/Ca‐derived BWTs of the Plio‐Pleistocene Caribbean Sea from the benthic foraminifer Cibicidoides wuellerstorfi are presented for the first time and interpreted along with Na/Ca and Sr/Ca as proxies of salinity and continental input, respectively. Our results highlight several warm (93, Gi15‐19, and N1) and cool (92, M2, Gi20, and CN4) marine isotope stages (MISs). Accordingly, changes in the circulation of deep‐water masses during the CAS closure developed in four main time intervals: (I) between 5.2 and 4.1 Ma (million years ago) BWT was ~1.1°C, (II) 4.1–3.2 Ma ~2.1°C, (III) 3.2–2.7 Ma ~2.7°C, and (IV) 2.7–2.2 Ma ~2.1°C. Relatively higher, gradually increased temperatures between 3.2 and 2.7 Ma correspond to late Pliocene warmth and restricted inflow of Pacific waters into the Caribbean due to shoaling of the CAS. In addition, Sr/Ca values reveal gradually escalating terrigenous input until 2.7 Ma most likely related to the increased river discharge in response to the Andean uplift. The gradual decrease of the BWTs from 2.7 Ma may have resulted from the onset of Northern Hemisphere Glaciation. Overall, BWTs match with previous sea surface temperatures from the planktic foraminifer Neogloboquadrina dutertrei. The BWTs presented here confirm intensified thermohaline circulation during the overall Pliocene warmth with increased bottom‐water Na/Ca values indicating enhanced salinity.
Employees’ Behavioral Intention to Adopt E-HRM System- An Approach to Extend Technology Acceptance Model

PurposeThis study aims to investigate the Information Technology (IT) sector employees’ behavioral intention towards the adoption of Electronic Human Resource Management (E-HRM) with the help of the Technology Acceptance Model (TAM) in the context of Bangladesh. Design/methodology/approachThe data for this study was collected through a structured questionnaire from 130 employees of IT sector in Bangladesh. The research model was developed based on the TAM theory with three external variables (organizational resources competency, organizational innovativeness and employee technical competency). The TAM theory extended by showing a direct relationship between organizational innovativeness and behavioral intention to adopt E-HRM. The data is analyzed by using SPSS 25. Multiple regression analysis was employed to examine the predictors and their relationships with behavioral intention to adopt E-HRM. FindingsThe results of the study showed that the respondents have a positive intention towards adopting E-HRM system. All three external variables have different effects on perceived usefulness and perceived ease of use. Most of the relationships are quite significant. Moreover, a strong direct relationship was found between organizational innovativeness and behavioral intention regarding EHRM adoption. Research limitationsThe dearth of empirical studies and to better understand the factors that influence the intention of employees towards E-HRM adoption in organizations is the main limitation of the study. Thus it is suggested to use more representative variables with a greater sample size in further studies. The study also had a geographical limitation. Practical implicationsThe research findings can provide an insight to all those business organizations who are planning to adopt E-HRM system and the human resource managers can use the results as an opportunity to develop HRM functions through E-HRM adoption. Originality/valueThis research contributes to the body of knowledge as it measures the employee intention towards E-HRM adoption by analyzing the influence of several factors thus enabling similar organizations to produce more vigorous proposals for E-HRM adoption.
Density Functional study of the photoactive yellow protein's chromophore

We have investigated the structural and electronic properties of p-coumaric acid, the chromophore of the photoactive yellow protein (PYP), by means of first-principles molecular dynamics based on density functional theory (DFT). We have studied the chromophore both in the vacuum and in an extended model which includes the nearest residues in the binding pocket of PYP, as derived from crystallographic data. We have characterized the ground state of the isolated chromophore in its protonated and deprotonated forms and computed the energy barrier involved in the trans to cis isomerization process around the carbon−carbon double bond. A comparison of the optimized structures of the chromophore in the vacuum and in the extended protein model, both in the trans (ground state of PYP in the dark) and cis (first light-activated intermediate) configuration, shows how the protein environment affects the chromophore in the first step of the photocycle. Our model gives an energy storage of 25 kcal/mol associated with .

FLOCCULATION OF ASPHALTENES AT HIGH PRESSURE. II. CALCULATION OF THE ONSET OF FLOCCULATION

ABSTRACT The influence of pressure on the onset of flocculation of asphaltenes was calculated in the region from 1 to 300 bar and from 50 to 100°C. These calculations are the counterpart to our experimental data which, recently, have been reported in part 1 of an equally titled article [9]. As gas component methane and as precipitant i-octane were used. The asphaltene flocculation was considered to be a liquid–liquid equilibrium. For modelling the van der Waals equation of state (vdW-EOS) in the framework of continuous thermodynamics was applied. The composition of the crude oil was described by a continuous distribution function with respect to the solubility parameter δ of the Scatchard-Hildebrand theory. Within the distribution the asphaltenes represent the species with the highest δ-values. For oils with a very low content of asphaltenes the model developed describes the experimental flocculation data reasonably. In accordance to the experimental data the model predicts that, in the considered pressure range, without addition of i-octane asphaltene flocculation does not occur. However, on contrary to the experimental results, the model predicts the asphaltenes to show a higher flocculation tendency with increasing asphaltene content of the crude oil. For very high asphaltene contents the model even completely fails. Probably, the reason of this lack is the disregarding of asphaltene association.
Influence of Swept Blades on Low-Order Acoustic Prediction for Axial Fans

The low-speed fans used for automotive engine cooling contribute to a significant part of the global noise emitted by the vehicle. A low-order sound-prediction methodology is developed considering the blade sweep-angle effect on the acoustic predictions of the turbulence-impingement and the trailing-edge noise-generating mechanisms. We modeled these through the application of a semianalytical method based on Amiet’s airfoil theory, appropriately adapted via a strip-theory approach accounting for rotation and modified to include the blades forward curvature. Sweep was already shown in the literature to reduce the noise emitted by isolated airfoils, but its effect on rotating machines was not yet well understood. In this study, we show that the effect of the sweep-angle is to globally reduce the emitted noise by the fan and to change the sound distribution of the sources along the blade span. Thus, the sweep-angle must be considered not only because it yields a better comparison with experimental results but also because wrong conclusions on the dominating noise-generating mechanisms can be drawn when this effect is not taken into account. The investigation is finally complemented by a sensitivity analysis focusing on some of the key parameters characterizing the acoustic prediction.
Discontinuous noun phrases in Yucatec Maya

Languages differ in whether or not they allow discontinuous noun phrases. If they do, they further vary in the ways the nominal projections interact with the available syntactic operations. Yucatec Maya has two left-peripheral configurations that differ syntactically: a preverbal position for foci or wh-elements that is filled in by movement, and the possibility to adjoin topics at the highest clausal layer. These two structural options are reflected in different ways of the formation of discontinuous patterns. Subextraction from nominal projections to the focus position yielding discontinuous NPs is possible, but subject to several restrictions. It observes conditions on extraction domains, and does not apply to the left branch of nominal structures. The topic position also appears to license discontinuity, typically involving a non-referential nominal expression as the topic and quantifiers/adjectives that form an elliptical nominal projection within the clause proper. Such constructions can involve several morphological and syntactic mismatches between their parts that are excluded for continuous noun phrases, and they are not sensitive to syntactic island restrictions. Thus, in a strict sense, discontinuities involving the topic position are only apparent, because the construction involves two independent nominal projections that are semantically linked.
