Published: October 2019

ABSTRACT
Groundwater is one of the valuable resources and due to increase in the population, industrialization and agriculture practices, the groundwater stress has increased to a greater extent. Once the groundwater gets contaminated, remediation is very difficult. The steps to measure the groundwater vulnerability must be taken for sustainable groundwater protection and management planning. In this paper, the DRASTIC model is applied to find out and generate a small-scale map of groundwater vulnerability to assess the contamination in the upper Palar river basin, Tamil Nadu, India. A number of tanneries are located along the banks of the river basin. The quality of groundwater in and around river basin area has been affected very much due to the untreated effluent of the tanneries discharged directly to the river. The DRASTIC model consists of seven hydrogeological parameters including depth to water table, net recharge, aquifer media, soil media, topography, impact of vadose zone and hydraulic conductivity; each factor is assigned by weight and rating which depends upon the influence of the seven hydrological layers of the river basin area. The ArcGIS 10.3 software was used to create the groundwater vulnerability map by overlaying the seven layers, which is intended to show potential areas of groundwater contamination. The results of the study shows that, 50% of the study area falls under very high pollution potential zone, 20% under high pollution potential, 15% under moderate pollution potential, 10% under low pollution potential, and the remaining 5% of the area has no risk. The very high vulnerability class which is covered by the alluvium along the river course is most likely to pollution due to the very lower slope terrains in the direction of the central part, which allows better percolation of contaminants into the groundwater. The low vulnerability class lies in the area covered by the hard rock and clay loam soil in the upper reach of the Palar river which contains mountains and hard rock terrain.

Abstract
A new fossil wood of Hopeoxylon i.e. H. umarsarensis sp. nov. showing close resemblance with the modern wood of Sindora/Copaifera of the subfamily Detarioideae (family Fabaceae) is described from the Umarsar lignite mine of Kutch basin, Gujarat that belongs to the Naredi Formation of the early Eocene age. Detarioideae is one of the reinstated subfamilies of the Fabaceae with diversity much higher in tropical Africa than in South America or Asia. The relics of this subfamily are known from the Paleocene onwards from various horizons of America, Africa, Europe, India and Southeast Asia. This is the oldest fossil record of the genus Sindora/Copaifera which contributes towards the understanding of the origin and palaeo-dispersal pathways of this early-diverging subfamily within the early branching Fabaceae.

Abstract
Increasing interest focuses on utilizing wetlands to reduce nutrient loading to surface waters. The current study examines soil P storage capacity in three treatment wetlands designed to decrease N loading from an agricultural tile drainage system in Illinois. Adjacent farm field and restored floodplain wetland soils were also evaluated. Results demonstrate that wetland soils sequestered P; however, the magnitude of P retention varied significantly across treatment systems and floodplain wetlands related to differences in soil properties. Soil P storage capacity increased in the direction of water flow, but varied across treatment wetlands; soils ranged from P sinks (5.8 ± 1.5 mg P kg−1) to potential P sources (−17.2 ± 2.0 mg P kg−1). Farm fields displayed the highest water soluble P levels (11.3 ± 1.5 mg P kg−1) and represented the largest potential source of P with a mean storage capacity of −48.6 ± 6.8 mg P kg−1. A phosphorus saturation ratio threshold value of 0.10 differentiated between potential P sources and sinks. Findings suggest wetlands receiving P loadings from tile drainage accumulate soil P over time, but maintaining P removal efficiency in treatment wetlands may require periodic management to decrease soil P concentrations via nutrient removal and/or soil amendments.

AbstractAdsorption desulfurization is a potential new method for deep desulfurization of fuel oil. The development of adsorbents with high adsorption capacity and selectivity is the core of deep adsorption desulfurization. The adsorption behavior of thiophene in MCM-41 mesoporous materials modified by various metal ions was studied in order to understand the adsorption desulfurization process of molecular sieves. The Fe-, Co-, and Zn-modified MCM-41 materials were prepared using a one-step in situ hydrothermal synthesis method. The modified MCM-41 molecular sieves maintained the mesoporous structure, and the metal ions had specific dispersion on the surface of the molecular sieves. Adsorption of thiophene on the surfaces of molecular sieves had both physical and chemical characteristics. The adsorption desulfurization performance of the modified molecular sieve was superior to that of the pure silica molecular sieve. In the simulated gasoline with sulfur content of 220 μg/g, when the amount of adsorbent used was 100 mg, the adsorptive desulfurization performance tended to be in equilibrium, and the optimum adsorption temperature was 30°C. Fe-MCM-41 and MCM-41 molecular sieves reached adsorption equilibrium after ~60 min, but the desulfurization rate of Co-MCM-41 and Zn-MCM-41 still increased slightly. The kinetic simulation results indicated that the pseudo-second-order kinetics adsorption model described well the adsorption process of thiophene on molecular sieves. The molecular sieve Fe-MCM-41 had the best desulfurization performance with an equilibrium adsorption capacity of 14.02 mg/g and the desulfurization rate was ~90%.

Published: October 2019

ABSTRACTAlong many flight corridors, bodies of water serve as preferred emergency landing options. Thus, relevant scenarios must be investigated to improve aircraft crashworthiness in the event of an impact landing on water. Enhancing the damage tolerance of aircraft structures through repetitive experiments can, however, prove highly uneconomical. Such large-scale trials can be influenced by many factors of uncertainty adversely affecting the quality of the results. Therefore, the work presented in this study focuses in particular on evaluating a computational methodology perfected for aircraft water ditching using Coupled Lagrangian-Eulerian (CLE) that allows detailed prediction of structural response of a verified deformable fuselage section during such events. Validation of the fluid-structure interactive (FSI) strategy developed is conducted, thoroughly comparing the method against the analytical and experimental results of multiple wedge drop tests. Finally, the validated FSI strategy is applied to a high-fidelity fuselage section model impacting water to simulate and assess a realistic ditching scenario.
From spectator to spect-actor: The proactive involvement of chinese parents in their conflicts with adolescents through a forum theatre format

Published: October 2019

AbstractParent-adolescent conflict seems to be common when adolescents negotiate power with their parents. Forum theatre (FT), an interactive and participatory theatre form, is recommended as a community-based intervention to assist Chinese parents in managing the challenges of parent-adolescent interaction. FT proposes that solutions to daily struggles can be reached through concerted efforts of the participants. This article documents the impact of FT on parents who took on the role of ‘spect-actor’. The spect-actor is an active spectator who acts on stage to test solutions to a problem. The results indicate that parents gained more awareness of their children’s needs, which helped them to relax their control over their children. FT is recommended as a means of parent education in schools.
“Men Diggers and Women Carriers”: Gendered Work on Famine Public Works in Colonial North India
Authors: Jha Madhavi 
Published: October 2019

AbstractThe history of labour on public works construction is usually presented as a masculine experience, either because the workforce studied is mostly male, or because the labour of women remains unrecorded. Does the history of labour and wage on public works undergo change if we account for women labourers? This article examines this question in the context of famine public works in the second half of nineteenth-century India. State employment on public works was part of a famine relief programme and women, largely from agricultural labouring and small peasant families, worked on the construction of roads, railways, canals, and tanks. The article traces the development of task-gender association on famine public works both as a norm and in practice. Further, it analyses the evidence on negotiations made by women labourers themselves with the existing gendered notions of work and wage. This study contributes to the historiography of labour in a colonial context in two ways: first, it adds to the existing corpus on forms of labour extraction for construction work; and, second, it explores the question of women's work and remuneration outside factories, mills, and mines.
The Magic Lantern as a Lens for Observing the Eye in Tokugawa Japan: Technology, translation, and theRangakumovement
Authors: BREMNER LEWIS 
Published: October 2019

AbstractThis article explores the thoughts and ideas associated with magic-lantern technology in late eighteenth- and early nineteenth-century Japan. Its primary focus is on trends in Japanese thought from the 1770s until the 1820s, with specific reference to theRangaku(‘Dutch Studies’) movement. The article examines connections between the magic lantern and a wider discourse within Japan on epistemology, knowledge about nature, and the study of the human body, centring upon the device's vital role in the endeavour to understand the workings of the human eye. Through this lens, a fresh perspective is offered on the role of critical analysis in the translation and interpretation of European texts in Tokugawa Japan, as well as on the shifting prominence of empiricism and deductive reasoning in Japanese epistemology. In this way, the history of the magic lantern is used to look beyond the prevailing West-centred narrative of global technological and intellectual development.

AbstractBackgroundPositive symptoms are a useful predictor of aggression in schizophrenia. Although a similar pattern of abnormal brain structures related to both positive symptoms and aggression has been reported, this observation has not yet been confirmed in a single sample.MethodTo study the association between positive symptoms and aggression in schizophrenia on a neurobiological level, a prospective meta-analytic approach was employed to analyze harmonized structural neuroimaging data from 10 research centers worldwide. We analyzed brain MRI scans from 902 individuals with a primary diagnosis of schizophrenia and 952 healthy controls.ResultsThe result identified a widespread cortical thickness reduction in schizophrenia compared to their controls. Two separate meta-regression analyses revealed that a common pattern of reduced cortical gray matter thickness within the left lateral temporal lobe and right midcingulate cortex was significantly associated with both positive symptoms and aggression.ConclusionThese findings suggested that positive symptoms such as formal thought disorder and auditory misperception, combined with cognitive impairments reflecting difficulties in deploying an adaptive control toward perceived threats, could escalate the likelihood of aggression in schizophrenia.

AbstractBackgroundStudies investigating the link between depressive symptoms and inflammation have yielded inconsistent results, which may be due to two factors. First, studies differed regarding the specific inflammatory markers studied and covariates accounted for. Second, specific depressive symptoms may be differentially related to inflammation. We address both challenges using network psychometrics.MethodsWe estimated seven regularized Mixed Graphical Models in the Netherlands Study of Depression and Anxiety (NESDA) data (N = 2321) to explore shared variances among (1) depression severity, modeled via depression sum-score, nine DSM-5 symptoms, or 28 individual depressive symptoms; (2) inflammatory markers C-reactive protein (CRP), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α); (3) before and after adjusting for sex, age, body mass index (BMI), exercise, smoking, alcohol, and chronic diseases.ResultsThe depression sum-score was related to both IL-6 and CRP before, and only to IL-6 after covariate adjustment. When modeling the DSM-5 symptoms and CRP in a conceptual replication of Jokela et al., CRP was associated with ‘sleep problems’, ‘energy level’, and ‘weight/appetite changes’; only the first two links survived covariate adjustment. In a conservative model with all 38 variables, symptoms and markers were unrelated. Following recent psychometric work, we re-estimated the full model without regularization: the depressive symptoms ‘insomnia’, ‘hypersomnia’, and ‘aches and pain’ showed unique positive relations to all inflammatory markers.ConclusionsWe found evidence for differential relations between markers, depressive symptoms, and covariates. Associations between symptoms and markers were attenuated after covariate adjustment; BMI and sex consistently showed strong relations with inflammatory markers.
Crosstalk between mitochondrial metabolism and oxidoreductive homeostasis: a new perspective for understanding the effects of bioactive dietary compounds

Published: October 2019

AbstractMitochondria play an important role in a number of fundamental cellular processes, including energy production, biosynthetic pathways and cellular oxidoreductive homeostasis (redox status), and their dysfunction can lead to numerous pathophysiological consequences. As the biochemical mechanisms orchestrating mitochondrial metabolism and redox homeostasis are functionally linked, mitochondria have been identified as a potential therapeutic target. Consequently, considerable effort has been made to evaluate the efficacy of natural compounds that modulate mitochondrial function. Molecules produced by plants (for example, polyphenols and isothiocyanates) have been shown to modulate mitochondrial metabolism/biogenesis and redox status; however, despite the existence of a functional link, few studies have considered the combined efficacy of these mitochondrial functions. The present review provides a complete overview of the molecular pathways involved in modulating mitochondrial metabolism/biogenesis and redox status. Crosstalk between these critical mechanisms is also discussed, whilst major data from the literature regarding their antioxidant abilities are described and critically analysed. We also provide a summary of recent evidence regarding the ability of several plant-derived compounds to target these mitochondrial functions. An in-depth understanding of the functional link between mitochondrial metabolism/biogenesis and redox status could facilitate the analysis of the biological effects of natural compounds as well as the development of new therapeutic approaches.
The politics of blame avoidance in complex delegation structures: the public transport crisis in Berlin
Authors: Bach Tobias , Wegrich Kai 
Published: October 2019

AbstractThe article analyses the public attribution of blame and the use of presentational strategies of blame avoidance in complex delegation structures. We theorize and empirically demonstrate that complex delegation structures result in the diffusion of blame to multiple actors so that a clear allocation of responsibility becomes more difficult. The article shows that public attribution of blame follows a distinct temporal pattern in which politicians only gradually move into the centre of the blame storm. We also find that blame-takers deploy sequential patterns of presentational management and use blame shifting to other actors as a dominant strategy. However, the analysis suggests that complex delegation structures impose limitations on blame-takers’ use of blame avoidance strategies, and that sequential presentational management becomes less useful over time. The article uses media content analysis to study blame games during a major crisis of the public transport system in Berlin, Germany.
Center frequency and bandwidth switchable substrate integrated waveguide filters
Authors: Cheng Fei , Lu Ping , Huang Kama 
Published: October 2019

AbstractThis paper presents center frequency and bandwidth switchable substrate integrated waveguide filters loaded with PIN diodes. The diodes are added in the slot on the surface of the resonators to switch the resonant frequencies and the coupling coefficients. Although the introduction of the slot causes extra radiation loss, it is small and acceptable. The proposed center frequency switchable filter has four center frequency switchable states of 1.78, 1.82, 1.88, and 1.91 GHz, while the bandwidth only changes ±0.64%. The bandwidth switchable filter has two states with 3 dB bandwidths of 70 and 103 MHz at a center frequency of 2.08/2.09 GHz. The measured performance of the fabricated filters shows good agreement with the simulation.

Published: October 2019

A splash experiment was carried out on a model soil–glass beads with a diameter of 425–600 μm using high‐speed cameras and sticky paper. Two different types of particles were involved in the process: droplets of water and glass beads. We argue that the result of splash of solid particles is best modeled as a stochastic point process, that is, a random number of randomly distributed points (beads) on a plane, and provide basic physical and statistical evidence that, in medium distance range (i.e., for our experiment, in the ranges of 29–64 mm), the splash may be modeled as the Poisson point process. We also argue that, in the range between 15 and 29 mm, a distribution different than Poisson is closer to reality. These two radically different types of distributions of numbers of beads in two regions reflect the fact that the solid phase of the splash involves two types of beads: those ejected in the early stage, traveling larger distances, and those ejected later, traveling shorter distances. Information on the distributions of and relations between the numbers of splashed particles in different regions may be instrumental in understanding mechanics and scale of the spread of pollutants/pathogens and plant diseases as a result of splash. Meanwhile, we describe the distributions of the total number of beads, the maximum range, and the average distance beads particles travel in a single experiment and discuss effectiveness of detection of beads by the cameras.

AbstractBuilding on an earlier study that confirmed the stability of the 405‐kyr eccentricity climate cycle and the timing of the Newark‐Hartford astrochronostratigraphic polarity time scale back to 215 Ma, we extend the magnetochronology of the Late Triassic Chinle Formation to its basal unconformity in scientific drill core PFNP‐1A from Petrified Forest National Park (Arizona, USA). The 335‐m‐thick Chinle section is imprinted with paleomagnetic polarity zones PF1r to PF10n, which we correlate to chrons E17r to E9n (~209 to 224 Ma) of the Newark‐Hartford astrochronostratigraphic polarity time scale. A sediment accumulation rate of ~34 m/Myr can be extended down to ~270 m, close to the base of the Sonsela Member and the base of magnetozone PF5n, which we correlate to chron E14n that onsets at 216.16 Ma. Magnetozones PF5r to PF10n in the underlying 65‐m‐thick section of the mudstone‐dominated Blue Mesa and Mesa Redondo members plausibly correlate to chrons E13r to E9n, indicating a sediment accumulation rate of only ~10 m/Myr. Published high‐precision U‐Pb detrital zircon dates from the lower Chinle tend to be several million years older than the magnetochronological age model. The source of this discrepancy is unclear but may be due to sporadic introduction of juvenile zircons that get recycled. The new magnetochronological constraint on the base of the Sonsela Member brings the apparent timing of the included Adamanian‐Revueltian land vertebrate faunal zone boundary and the Zone II to Zone III palynofloral transition closer to the temporal range of the ~215 Ma Manicouagan impact structure in Canada.
