A new vertebrate fauna from the Triassic of the Deccan, India

Recent work on the Upper Gondwana Maleri Formation has enabled a more accurate and extended faunal list to be given, consisting of various kinds of fishes (dipnoans, subholostean, pleuracanth), reptiles (especially rhynchosaur, phytosaur, and aetosaurid), and a metoposaurid amphibian. A better estimate can thus be made of the age of the Maleri Formation as Upper Triassic, equivalent to the Carnian–Middle Norian Zones (inclusive) of the standard marine Triassic sequence. An Upper Gondwana inlier south-southeast of the main Maleri outcrop contains fossiliferous Maleri red clays and also a second red clay belt with a different vertebrate fauna, the Yerrapalli fauna, consisting of reptiles (including a large dicynodont and probably a theriodont and an erythrosuchoid) and amphibians, one of which may be a very large capitosaur. The new fauna seems similar in age to that of the South African Cynognathus Zone, i.e. late Lower Triassic. A fauna of this age has not previously been found in the continental Gondwana rocks of India, and if the preliminary results are confirmed it will be necessary to recognize a separate Yerrapalli Formation within the Gondwana sequence.
MgO-based cements – Current status and opportunities

The cement industry is a major contributor to the anthropogenic CO2 emissions, with about 8% of all emissions coming from this sector. The global cement and concrete association has set a goal to achieve net-zero CO2 concrete by 2050, with 45% of the reduction coming from alternatives to Portland cement, substitution, and carbon capture and utilization/storage (CCU/S) approaches. Magnesia-based cements offer a conceivable solution to this problem due to their potential for low-to-negative CO2 emissions (CCU/S) but also being alternatives to Portland cement. The sources of magnesia can come from magnesium silicates or desalination brines which are carbon free for raw-material-related emissions (cf. carbonated rocks). This opens up possibilities for low or even net-negative carbon emissions. However, research on magnesia-based cements is still in its early stages. In this paper, we summarize the current understanding of different MgO-based cements and their chemistries: magnesia oxysulfate cement, magnesia oxychloride cement, magnesia carbonate cement, and magnesia silicate cement. We also discuss relevant research needed for MgO-based cements and concretes including the issues relating to the low pH of these cements and suitability of steel reinforcement. Alternatives reinforcements, suitable admixtures, and durability studies are the most needed for the further development of MgO-based concretes to achieve a radical CO2 reduction in this industry. Additionally, techno-economic and life cycle assessments are also needed to assess the competition of raw materials and the produced binder or concrete with other solutions. Overall, magnesia-based cements are a promising emerging technology that requires further research and development to realize their potential in reducing CO2 emissions in the construction industry.
Unforced Surface Air Temperature Variability and Its Contrasting Relationship with the Anomalous TOA Energy Flux at Local and Global Spatial Scales

AbstractUnforced global mean surface air temperature () is stable in the long term primarily because warm anomalies are associated with enhanced outgoing longwave radiation () to space and thus a negative net radiative energy flux (, positive downward) at the top of the atmosphere (TOA). However, it is shown here that, with the exception of high latitudinal and specific continental regions, warm unforced surface air temperature anomalies at the local spatial scale [T(θ, ϕ), where (θ, ϕ) = (latitude, longitude)] tend to be associated with anomalously positive N(θ, ϕ). It is revealed that this occurs mainly because warm T(θ, ϕ) anomalies are accompanied by anomalously low surface albedo near sea ice margins and over high altitudes, low cloud albedo over much of the middle and low latitudes, and a large water vapor greenhouse effect over the deep Indo-Pacific.It is shown here that the negative versus relationship arises because warm anomalies are associated with large divergence of atmospheric energy transpo.
SOCIAL SUPPORT IN ACCESSING ADOLESCENTS MENTAL HEALTH SERVICES

Introduction: The survey reported that adolescents experienced severe depression (15.6%) and extreme stress (6.3%) in Warungboto, Yogyakarta, Indonesia. In fact, with this condition, they are reluctant to access mental health services. Adolescents' skills still lacking in problem-solving and inadequate social support are thought to be the triggering factors for low access to health services. Aims: to determine the social support for adolescents in accessing mental health services. Methods: This type of research is quantitative research with a cross-sectional approach. The unit of analysis is adolescents (15-24 years) who are identified as having stress and depression based on the results of early detection of mental health. The sample size is 36 teenagers, with a total sampling technique. The variables are family support, peer support, mental health status, problem-solving, and self-control measured in the questionnaire. Meanwhile, mental health status was assessed using DASS-21 and PSS-10. Results: There was a significant relationship between social support from family (p-value 0.001, 95% CI 1.581-76.551) and peers (p-value 0.018, 95% CI 1.108 – 2.608) with adolescent mental health status. Adolescents with depression and stress are very few who get good social support from their families in accessing mental health services. This study proves that family social support is a significant factor in accessing mental health services. Conclusion: Family involvement in overcoming adolescent mental health problems is crucial. However, health providers can also provide community-based mental health services with a peer approach.
Moderating Effect of Performance Evaluation Behavior Linking Perceived Risk Return Analysis of Selected Large Cap and Flexi Cap Mutual Funds in India

Aim - The study aims to understand the impact of risk and return on the performance evaluation of Large Cap and Flexi-Cap Mutual Funds in India. This study further evaluates the moderating role of fund rating about performance evaluation behavior of Large Cap and Flexi-Cap Mutual Fund schemes in India. Methods-The portfolio evaluation of Large Cap and Flexi-Cap Mutual Fund schemes in India using volatility measures such as quantitative factors like Total Risk (Standard Deviation), Beta, systematic risk and unsystematic risk the ratios such as Sharpe and Jensen’s Alpha. Data for research are collected from the secondary data sources and selected from 25 Large Cap Mutual Fund schemes and 30 Flexi-Cap Mutual Fund schemes in India. The collected data were examined using a Partial Least Squares (PLS) Structural Equation Modeling (SEM) modeling approach was employed for fulfilling the objective of study. Results/Findings – According to the data, the reliability indicator displays values for all indicators with loading factors more than 0.70 and Average Variance Extracted (AVE) values greater than 0.50. The composite dependability has a Cronbach alpha score of 0.70 or above for internal consistency reliability. Exogenous variables such as risk and return can be utilized to predict the endogenous variable of risk adjusted return (85%), with the remaining 20% influenced by factors outside the scope of this study. The predictive modeling power of the endogenous risk adjusted return variable is high (0.855). Exogenous variables such as risk and return can be utilized to predict the endogenous variable of risk adjusted return (85%), with the remaining 20% influenced by factors outside the scope of this study. Risk behaviour has been shown to operate as a moderator of the link between risk and return components and risk adjusted returns. According to the criteria (0.02 = weak/low, 0.15 = moderate, and 0.35 = strong/high), external latent factors have a significant impact on endogenous variables. Conclusion - The moderating role of Performance Evaluation Behavior (PEB) for decision making regarding Risk adjusted returns provides important insights for the investing sector. Therefore, it can be said that the Performance Evaluation Behavior (PEB) moderation is higher in the Risk than Return when analyzing the relationship with Risk adjusted returns.
Exploring and Evaluating the Consequences of Vector-to-Raster and Raster-to-Vector Conversion

Spatial data can be represented in two formats, raster (grid cell) or vector (polygon). It is inevitable that conversion of the data between these two formats be essential to the best use of the data. Most geographic information systems (GIS) now provide software for such a conversion. The objective of this study was to explore and evaluate the consequences of data conversion on the accuracy of the resulting data layer. Simple shapes were chosen to document the results of the raster-to-vector and vector-to-raster conversion processes. These shapes included a square, a triangle (not aligned with the grid), a circle, a hole within the circle, and a non-convex shape. Error matrices were employed to represent the changes in area through the conversion process. A second set of data including a circle, a thin rectangle, and a wide rectangle were used to examine the effect of grid cell size on both presence/absence of a feature as well as to maintain the feature's shape. Finally, recommendations for continuing this work and its application to information derived from remotely sensed data were presented.
Determination of Potential Evapotranspiration Using the Fuzzy Regression Method

Potential evapotranspiration (ET 0) rates are needed for irrigation scheduling. ET 0 rates are commonly from weather parameters. The Penman-Monteith, is now accepted for computation of ET 0. It requires several input parameters, some of which have no actual measurements but are estimated from measured weather parameters. In this study, the suitability of fuzzy regression was examined fo r estimating daily potential evapotranspiration with grass reference crop and compared with Artificial Neural Networks (ANN) and Penman-Monteith methods.The daily climatic data of the Ekbatan station in Hamadan, including maximum and minimum temperature, maximum and minimum relative humidity, wind speed and sunny hours are introduce d as input data and ET 0 as output data. ET 0 values estimated from the fuzzy regression method were compared with direct ET 0 measurements from lysimeters, and with ET 0 estimations obtained using the Penman-Manteith equation and the ANN method. The estimated ET 0 values from a fuzzy regression model using five input parameters, including maximum and minimum temperature, mean relative humidity, wind speed and sunny hours were obtained with RMSE=0.69mm/day, 2 R =0.88. The estimated ET 0 values from a artificial neural networks model using the same input parameters were obtained with RMSE=0.74mm/day, 2 R =0.84. The estimated ET 0 values from Penman-Monteith model were obtained with RMSE=1.21mm/day, 2 R =0.84. Thus, in this study the fuzzy regression is the best method.
Wideband Stacked Tightly Coupled Patch Array With Parasitic Strips

A low-profile wideband stacked tightly coupled patch array (TCPA) with parasitic strips is presented in this brief. Analyzed via a two-port network and originated from the traditional TCPA, the evolution of TCPA element is conducted by gradually introducing superstrate, parasitic patch and parasitic strips, and the ultimate one can exhibit an impedance bandwidth of 131.9%. Then, employing a practical feeding structure enables the implementation of the element to operate in a 102.0% band. Eventually, a $6\times 6$ prototype is constructed to verify the design correctness, and the results reveal that the working band is 2.4-6.8 GHz (94.6%) with VSWR less than 2, while the TCPA can respectively scan from −60° to 60° and from −40° to 40° in the E-plane and H-plane with VSWR<3. On account of its compact size, wide band, ascendant radiation characteristics and scanning performance, the proposed TCPA is promising in the application of large-scale arrays and communication systems.

Using Naïve Forecasts to Assess Limits to Forecast Accuracy and the Quality of Fit of Forecasts to Time Series Data

Naive 1 forecasts are often used as a benchmark when assessing the accuracy of a set of forecasts. A ratio is obtained to show the upper bound of a forecasting method's accuracy relative to naive 1 forecasts when the mean squared error is used to measure accuracy. Formulae for the ratio are presented for several exemplar time series processes. The practical use of the ratio as a warning that forecasts have failed to adequately filter the time series signal from the noise is demonstrated.
An efficient spectral minimization of the Dai-Yuan method with application to image reconstruction

In this paper, a spectral Dai and Yuan conjugate gradient (CG) method is proposed based on the generalized conjugacy condition for large-scale unconstrained optimization, in which the spectral parameter is motivated by some interesting theoretical features of quadratic convergence associated with the Newton method. Accordingly, utilizing the strong Wolfe line search to yield the step-length, the search direction of the proposed spectral method is sufficiently descending and converges globally. By applying some standard Euclidean optimization test functions, numerical results reports show the advantage of the method over some modified Dai and Yuan CG schemes in literature. In addition, the method also shows some reliable results, when applied to solve an image reconstruction model.
Flipped classroom in EFL: a teaching experience with pre-service teachers

This research aims to test a flipped classroom model to improve students’ English proficiency. To achieve this goal, two research questions were posed: RQ1 “Does the suggested model of flipped classroom teaching strategy increase the learners’ accuracy in the use of grammar in the target language more than the non-flipped active-learning strategy used? ” and RQ2 “Does the suggested model of Flipped Classroom teaching strategy increase learners’ listening skills in the target language more than the non-flipped active-learning strategy used? ” The participants involved in the study were 55 students from the Faculty of Education, University of Trnava (Slovakia), comprising 45 females and 10 males. All participants were pre-service teachers of English language and literature in their first year of undergraduate studies. The research had a semi-experimental pre-test/post-test design which was given to the control and the experimental group. The results show that students in the flipped classroom had a statistically significant positive effect on the participants’ listening skills. As for grammar, both the control and the research group improved, but the results were not statistically significant. These findings partially match former studies, where language accuracy was also an indicator of flipped classroom success. The implications of this research are high since listening, often referred to as the “Cinderella” of language skills, has frequently been overlooked in EFL classes, leading to students not reaching expected proficiency levels.

Neutron Star Constraints on Neutron Dark Decays

Motivated by the neutron lifetime puzzle, it is proposed that neutrons may decay into new states yet to be observed. We review the neutron star constraints on dark fermions carrying unit baryon number with masses around 939 MeV, and discuss the interaction strengths required for the new particle. The possibility of neutrons decaying into three dark fermions is investigated. While up to six flavors of dark quarks with masses around 313 MeV can be compatible with massive pulsars, any such exotic states lighter than about 270 MeV are excluded by the existence of low-mass neutron stars around ∼1.2M⊙. Light dark quarks in the allowed mass range may form a halo surrounding normal neutron stars. We discuss the potential observable signatures of the halo during binary neutron star mergers.
Toward Understanding the Spectroscopic Performance and Charge Transport Mechanisms of Methylammonium Lead Tribromide Perovskite X- and γ-Rays Detectors

Organic–inorganic perovskites have shown to be promising materials with great potential for use in radiation detection, in which higher energy photons or heavy charged alpha particles need to be detected. Their superior characteristics, such as relatively high atomic number and larger density, tunable bandgap, high resistivity, and large carrier mobility-lifetime product, provide higher stopping power for X-rays and high detection efficiency, combined with a facile preparation and lower costs. In this study, p-i-n-type devices based on high-resistivity MAPbBr3 single crystals are investigated as detectors of X- and $\gamma $ -rays. The analysis of current–voltage characteristics and spectrometric properties of the detectors allowed to determine the main parameters of the MAPbBr3 crystal. The voltage-dependent charge transport mechanisms of the investigated p-i-n-type devices can be well described in terms of well-known theoretical models. The obtained electrical performance parameters indicate that the MAPbBr3 single crystals satisfy requirements for radiation detection applications. However, the MAPbBr3 crystal quality as well as the device architecture need optimization to decrease the leakage current and enhance the transport properties of charge carriers and thus to improve the energy resolution of the detectors.
PCAS 15 (2012/2013) Critical Literature Review (ANTA602) Tourism in Antarctica: Finding a Balance for the Future

Antarctic Tourism has increased significantly over the past fifty years, as has global tourism. This review sets out to consider how this increase in tourist numbers, which appears to be inevitable, is impacting on Antarctica. Is the current legislation sufficient for management of the negative impacts of tourism? If not, what is being suggested as a possible way to mitigate these impacts? Tourism has positive impacts as well, and the future for Antarctica appears to be finding a way forward by recognizing the value tourists bring and balancing this alongside manageable regulations to mitigate the negative impacts.
The changing nature of flood risk: Portsmouth, Hampshire

The nature of flood risk is affected by numerous factors both natural and anthropogenic, these factors are constantly changing and so with it the nature of flood risk throughout the UK. The City of Portsmouth was recently identified as one of the most vulnerable urban areas to storm surge risk and has a recent history of urban flood events. This report assess how the 'risk' of flooding is set to change in the future, this has been conducted within the framework that risk consists of two elements; the hazard and vulnerability towards it. A combination of desktop research, analysis of observational and collection of primary data allowed for confident assertions to be made. Observational data pertaining to both sea surface and rainfall data in Portsmouth was analysed to identify changes in the flood hazards and determine trends and make future predictions in order to make risk reduction recommendations. The report also analyses the awareness and attitudes of flood risk of a sample group of Portsmouth residents. It was discovered that the risk of both flood hazards is on the increase and the awareness of these hazards is low. The information collected has allowed for several key recommendations to be made to reduce and manage the risk effectively.
