Assessment of Neighbor‐Initiated Risks in an Integrated Air Separation Unit‐Gasification Facility
Authors: Cialkowski Edward J , Li Yuqiang 
Published: January 2019

Gasification facility operators increasingly find it cost effective to outsource the supply of industrial gases, such as oxygen and nitrogen, to companies with a proven track record for designing and operating safe and reliable air separation unit (ASU) equipment. Air Products have built & operated many such ASU facilities in recent years and supplied industrial gases to customers directly by pipeline, with long term supply partnerships. Most of these ASU facilities are located within the customer boundary and are effectively integrated with customer gasification facilities. In addition to any risks that the ASU may pose to the customer's operations or personnel, there may be significant hazards originating with the customer's equipment or processes that pose a risk to the ASU personnel.Air Products developed an approach to assessing risks from neighboring facilities to the ASU equipment and personnel. The focus of this article is on the work process and sequence of steps used to develop a risk assessment and mitigation plan. Overall safety and risk management is improved by sharing hazard information between the industrial gas supplier and the customer, as well as developing a joint emergency response program. © 2019 American Institute of Chemical Engineers Process Saf Prog 38: e12032, 2019
Transverse function control with prescribed performance guarantees for underactuated marine surface vehicles
Authors: Dai Shi‐Lu , He Shude , Lin Hai 
Published: January 2019

SummaryThis paper studies the problem of stabilizing reference trajectories (also called as the trajectory tracking problem) for underactuated marine vehicles under predefined tracking error constraints. The boundary functions of the predefined constraints are asymmetric and time‐varying. The time‐varying boundary functions allow us to quantify prescribed performance of tracking errors on both transient and steady‐state stages. To overcome difficulties raised by underactuation and nonzero off‐diagonal terms in the system matrices, we develop a novel transverse function control approach to introduce an additional control input in backstepping procedure. This approach provides practical stabilization of any smooth reference trajectory, whether this trajectory is  feasible or not. By practical stabilization, we mean that the tracking errors of vehicle position and orientation converge to a small neighborhood of zero. With the introduction of an error transformation function, we construct an inverse‐hyperbolic‐tangent‐like barrier Lyapunov function to show practical stability of the closed‐loop systems with prescribed transient and steady‐state performances. To deal with unmodeled dynamic uncertainties and external disturbances, we employ neural network (NN) approximators to estimate uncertain dynamics and present disturbance observers to estimate unknown disturbances. Subsequently, we develop adaptive control, based on NN approximators and disturbance estimates, that guarantees the prescribed performance of tracking errors during the transient stage of on‐line NN weight adaptations and disturbance estimates. Simulation results show the performance of the proposed tracking control.
Biofilm modeling in evolving porous media with Beavers‐Joseph condition
Authors: Schulz Raphael 
Published: January 2019

AbstractIn this article, we derive an effective model for biofilm growth in a saturated porous medium. Several experimental investigations found out that biomass is in general very heterogeneous and contains in particular channels filled with fluid. These channels facilitate the transport of nutritive substances within the biofilm by advection. Referring to this, we model the biofilm itself at the pore‐scale as a porous medium. Hence the starting point at the pore‐scale is a Darcy‐Stokes system, where the Beavers‐Joseph boundary condition at the corresponding interface is proposed. By formal periodic homogenization we derive an averaged model describing the process via Darcy's law and upscaled transport equations with effective coefficients given by the evolving microstructure. Based on the assumption of uniform evolve of the underlying pore geometry, solvability in a weak sense global in time or at least up to a possible clogging phenomenon is stated.
The Place of the Holy Man in the Later Roman Empire
Authors: MacMullen Ramsay 
Published: January 2019

AbstractThe early centuries in the history of Christian asceticism, and of monasticism to which it gave rise, invite a short and accessible overview. The present article aims to supply this. It relies on a very large sampling of texts, mostly hagiographic. As ascetics are there to be seen described by contemporaries and near-contemporaries, they share many traits which can be grouped under principal headings and frequency of mention. A statistical profile emerges, presented under numerous headings and totals which in turn indicates the ascetics’ most salient aims and acts, and helps to explain the course of development of their institutions. The findings challenge a still-famous and almost universally accepted overview offered by Peter Brown (1971). This the present article seeks to replace at the outset, through calling in question Brown’s methodological assumptions, and second, in its closing pages, through challenging Brown’s picture of the holy man in other, more factual points.
Parasites in Antarctic krill guts inferred from DNA sequences

Published: January 2019

AbstractThe keystone role of Antarctic krill,Euphausia superbaDana, in Southern Ocean ecosystems, means it is essential to understand the factors controlling their abundance and secondary production. One such factor that remains poorly known is the role of parasites. A recent study of krill diet using DNA analysis of gut contents provided a snapshot of the parasites present within 170E. superbaguts in a small area along the West Antarctic Peninsula. These parasites includedMetschnikowiaspp. fungi,Haptoglossasp. peronosporomycetes,LankesteriaandParalecudinaspp. apicomplexa,Stegophorussp. nematodes, andPseudocolliniaspp. ciliates. Of these parasites,Metschnikowiaspp. fungi andPseudocolliniaspp. ciliates had previously been observed inE. superba, as had other genera of apicomplexans, though notLankesteriaandParalecudina.In contrast, nematodes had previously only been observed in eggs ofE. superba, and there are no literature reports of peronosporomycetes in euphausiids.Pseudocolliniaspp., parasitoids which obligately kill their host, were the most frequently observed infection, with a prevalence of 12%. The wide range of observed parasites and the relatively high frequency of infections suggest parasites may play a more important role than previously acknowledged inE. superbaecology and population dynamics.

AbstractBullying has been understudied among preschool children, especially those from Chinese American families. Previous research has also neglected the dimensional effects of psychological control on child bullying development. This study examined two psychological control dimensions, love withdrawal and guilt induction, and their effects on children's bullying aggressive behavior using a longitudinal design. Participants were first-generation Chinese American mothers (N= 133; mean age [Mage] = 37.82) and their preschool children (Mage= 4.48). Chinese immigrant mothers reported their psychologically controlling parenting and teachers rated children's bullying aggressive behaviors in the school setting. Confirmatory factor analyses were conducted to establish the psychometric properties and cross-wave measurement equivalence of the study constructs. Cross-lagged structural equation modeling analysis indicated that maternal love withdrawal prospectively predicted more bullying aggressive behavior, whereas guilt induction predicted less bullying aggressive behavior in children 6 months later. These results held after controlling for the initial level of children's problem behaviors and demographic variables (child age, gender, and maternal education). For child effects, child bullying aggressive behavior predicted more maternal guilt induction over time but not love withdrawal. Our findings highlight the importance of construct specificity and cultural context in understanding associations between parenting and child development.

Published: January 2019

AbstractObjectiveGrief is intertwined with cultural and religious rituals that are highly appreciated in the quality standards of palliative care. Here, we aimed to investigate whether a cultural mourning ritual, the “First Feast,” can be used by palliative care teams to ease the grief response of the deceased patient's relatives.MethodA questionnaire with 23 questions about the prevalence of the First Feast tradition, the content, the pros and cons, and whether it would be useful for the grieving relatives of deceased patients was prepared and given to the palliative care patients’ relatives. The data were evaluated using the chi-square test.ResultA total of 427 participants were enrolled in the study; 60.7% were female and the mean age was 36 (±13.4). A total of 76.8% of the participants were from the Tokat region and 77.8% (n = 332) performed the First Feast tradition. A significant difference was observed among participants with Tokat origins and non-Tokat origins in terms of awareness of the tradition (84.8% and 69.7%, respectively; p = 0.001). Ninety-one percent of the participants acknowledged that the tradition helped to ease the grief response of the relatives.Significance of resultsThe First Feast, a mourning tradition performed in Tokat and other parts of Turkey, might be a useful auxiliary method for palliative care teams to help grieving families.
Bringing the Church Back In: Ecclesiastical Influences on the Rise of Europe
Authors: Møller Jørgen 
Published: January 2019

AbstractRecently, political scientists and economists have redoubled their attempts to understand the “Rise of Europe.” However, the role of the Catholic Church has been curiously ignored in most of this new research. The medieval West was shot through with Catholic values and institutions, and only by factoring in the Church can we understand the peculiar European development from the high Middle Ages onward. More particularly, the 11th century “crisis of church and state” set in train a series of developments that were crucial for the Rise of Europe. The Church was the main locale in which the development of representation, consent, and early bureaucratic institutions took place, and it contributed to creating, integrating, and maintaining the European multistate system. This note demonstrates that current scholarship has failed to factor in ecclesiastical influences and it shows how these gaps can be filled by a more careful reading of prior historical scholarship.

AbstractEnvironmental factors during perinatal life can lead to changes in the mammary gland, making it susceptible to cancer in adulthood. Breastfeeding has a special importance since it takes place at a critical period of growth and development of the newborn. We aimed to analyze if an appropriate lactation protects the offspring against mammary carcinogenesis during adult life and explore the mechanisms involved in the protective effect. One-day-old Sprague-Dawley female rats were randomly distributed in litters of three (L3), eight (L8) or 12 (L12) pups per dam, to induce a differential consumption of breast milk. At 55 days of age, the animals were treated with a single dose of dimethylbenzanthracene to study tumor latency, incidence and progression. Histological, immunohistochemical and Western blot studies were performed. We observed lower incidence and higher latency in L3 compared to the other groups. The mitotic index and expression of proliferating cell nuclear antigen (PCNA) was significantly augmented in tumors of L12 rats compared to L3 and L8, while the apoptotic index was augmented in tumors of L3 v. L12. Cleaved caspase 8 was significantly higher in tumors from L3 compared to L12. Tumors developed in L3 have a greater number of apoptotic bodies and a greater expression of caspase 8. These results demonstrate that the animals that maintained a higher intake of maternal milk (L3) presented lower incidence and greater tumor latency. Lower consumption of breast milk (L12) would increase tumor mitosis and the expression of PCNA, explaining the higher tumor incidence observed in this group.
The role of offspring’s birthweight on the association between pre-pregnancy obesity and offspring’s childhood anthropometrics: a mediation analysis

Published: January 2019

AbstractWhile birthweight of offspring is associated with pre-pregnancy body mass index (BMI) and later risk of obesity, its mediating effect between the association of maternal pre-pregnancy BMI and offspring’s childhood anthropometrics has rarely been investigated. This study aimed to examine whether offspring birthweight is a mediator in the association between pre-pregnancy BMI and offspring’s childhood anthropometrics. The study included 1,618 mother–child pairs from the Australian Longitudinal Study on Women’s Health and Mothers and their Children’s Health Study. Children’s anthropometrics [mean age 8.6 (s.d. =3.0) years] were calculated from the mothers’ self-reported child weight and height measures. G-computation was used to estimate the natural direct and indirect (via birthweight) effects of pre-pregnancy BMI. In the fully adjusted model for maternal sociodemographic and lifestyle factors, the natural direct effects of pre-pregnancy obesity on child BMI-for-age, height-for-age, weight-for-age and weight-for-height outcomes were, β (95% confidence interval, CI), 0.75 (0.55, 0.95), 0.13 (−0.07, 0.32), 0.62 (0.44, 0.80) and 0.57 (0.24, 0.90), respectively. The corresponding natural indirect effects were 0.04 (−0.04, 0.12), −0.01 (−0.09, 0.07), −0.01 (−0.08, 0.07) and 0.09 (−0.05, 0.23). Similar results were observed for pre-pregnancy overweight and pre-pregnancy BMI as a continuous scale. Most of the effect of pre-pregnancy obesity on childhood weight-related anthropometric outcomes appears to be via a direct effect, not mediated through offspring’s birthweight.
Networks of Resilience: Legal Precarity and Transborder Citizenship among the Karen from Myanmar in Thailand
Authors: Balčaitė Indrė 
Published: January 2019

AbstractThis study probes the relationship between legal precarity and transborder citizenship through the case of the Karen from Myanmar in Thailand. Collected through ethnographic multi-sited fieldwork between 2012 and 2016, interconnected individual life stories evolving across the Myanmar-Thailand border allow the critical interrogation of the political and legal categories of ‘migrancy’, ‘refugeeness’, and ‘citizenship’, teasing out their blurry boundaries in migrants’ experience. Following the recent critical research in legal ethnography, this study demonstrates that legal precarity is not simply an antithesis to citizenship. The social and legal dimensions of citizenship may diverge, creating in-between areas of not-yet-full-citizenship with varying levels of heft (Macklin 2007). The article consists of three parts. First, it offers a theoretical framework to reconcile the Karen legal precarity (even de facto statelessness) and citizenship, even on both sides of the border (legally impossible). Second, it presents the three groups of Karen in Thailand, produced by the interaction of three major waves of Karen eastward migration and tightening Thai citizenship and migration regulations: Thai Karen, refugees, and migrant workers. All three face varying levels of legal precarity of temporary status without full citizenship. However, the last part demonstrates the intertwined nature of those groups. A grassroots transborder perspective reveals the resilience of the Karen networks when pooling together resources of the hubs established on Thai soil by the three waves. Even the most recent arrivals in Thailand use those resources to move from one precarious legal status to another and even to clandestinely obtain citizenship.
Seed Germination Ecology of Soldier Thistle (Picnomon acarna): An Invasive Weed of Rainfed Crops in Iran
Authors: Nosratti Iraj , Almaleki Sajad , Chauhan Bhagirath S. 
Published: January 2019

AbstractSoldier thistle [Picnomon acarna(L.) Cass.] is widely distributed throughout rainfed fields across western Iran, where it decreases crop yields and interferes with harvest operations. This study was conducted to determine the influence of different factors on seed germination and seedling emergence ofP. acarna. Freshly harvested seeds were dormant and required an after-ripening period for breaking dormancy. Seed germination was greatly promoted by light. Germination occurred over a wide spectrum of constant and fluctuating temperature regimes, ranging from 5 to 35 C, with highest germination at constant (74%) and fluctuating (94%) temperatures of 20 and 20/10 C. Seed germination ofP. acarnawas tolerant to osmotic potential, while salt stress significantly inhibited its germination percentage. pH was not an inhibiting factor for germination ofP. acarnaseeds. Seedling emergence decreased exponentially with an increase in seed burial depth in the soil; at soil burial depths of 4 cm or greater, no seedlings were able to reach the soil surface. The results suggest that significant seed germination ofP. acarnain rainfed fields is possible, and the weed has great potential to spread throughout rainfed systems in western Iran. Based on these results, effective control ofP. acarnacan be achieved by applying interrow cultivation in row crops and deep tillage at seedbed preparation.

Published: January 2019

AbstractObservations of Jovian broadband kilometric (bKOM) radiation and ultraviolet (UV) auroras were acquired with the Waves and Juno‐UVS instruments for ∼2 hr over the northern and southern polar regions during Juno's perijoves 4, 5, and 6 passes (PJ4, PJ5, and PJ6). During all six time periods, Juno traversed auroral magnetic field lines connecting to the UV main auroral ovals, matching the estimates of bKOM radio source footprints. The localized bKOM radio sources for the PJ4 north pass map to magnetic field lines having distances of 10 to 12 Jovian radii (RJ) at the magnetic equator, whereas the extended bKOM radio sources for the other events map to field lines extending to 20–61 RJ. We found the peak bKOM intensities during Juno's potential radio source crossings show positive, negative, and no correlations with the UV main oval brightness and color ratio. Only the positive correlations suggest wave‐particle energy transport.
Magnetodisk Coordinates for Saturn
Authors: Carbary J. F. 
Published: January 2019

AbstractThe magnetosphere of Saturn is known to be warped into a bowl shape, and the severity of the warping varies with the seasonal tilt of Saturn's spin axis in its orbital plane. This peculiar geometry complicates the analysis of many magnetospheric phenomena, because they are symmetric about the warped magnetodisk equator rather than the spin equator. To reorganize the Cassini data, a new coordinate system is proposed wherein a zA coordinate represents the perpendicular distance above or below the warped surface, and a ρA coordinate represents the arc length along the surface from the origin to where the perpendicular intersects the surface. Using the Cassini spacecraft trajectory, examples show how these disk coordinates (ρA, zA) significantly deviate from the standard spin‐equatorial coordinates (ρ, z), especially outside the orbit of Titan. Another example indicates that fluxes of energetic electrons are well organized in this new system. Supporting information tabulates the disk coordinates as a function of time during the Cassini mission.
New Diagnosis for Energy Flow From Solar Wind to Ionosphere During Substorm: Global MHD Simulation
Authors: Ebihara Y. , Tanaka T. , Kamiyoshikawa N. 
Published: January 2019

AbstractTo investigate the energy involved by a substorm, we performed global magnetohydrodynamics simulation for different solar wind conditions. The intensity of the auroral electrojet increases with the southward component of interplanetary magnetic field (IMF) and the solar wind velocity, which is consistent with observations. To evaluate the energy that enters the magnetosphere, we first defined a solar wind effective cross‐sectional area in which all the Poynting fluxes entering the magnetosphere pass through. We found that the solar wind magnetic energy is insufficient to provide the magnetic energy entering the magnetosphere (intake magnetic energy) for southward IMF. About 33–88% of the intake magnetic energy is converted from the solar wind kinetic energy. About 2–7% of the solar wind kinetic energy (passing through the effective area) is converted to the magnetic energy that enters the magnetosphere. Significant contribution from the solar wind kinetic energy makes the energy coupling function complicated. The effective area also depends on the solar wind parameters, also making it complicated. An interesting point is that the rates of energy stored and released in the lobe also depend on the solar wind parameters. The ionospheric Joule heating rate is well correlated with the intake magnetic energy at onset, and during the substorm expansion. The correlation coefficients between them are better than that of the ε parameter. These results imply that both the directly driven process (manifested by intake magnetic energy) and loading‐unloading process (manifested by stored/released energy in the lobe) are largely regulated by the solar wind condition.
Green Icebergs Revisited
Authors: Warren Stephen G. , Roesler Collin S. , Brandt Richard E. , Curran Mark 
Published: January 2019

AbstractIce crystals form in supercooled seawater beneath several Antarctic ice shelves; as they rise to the ice‐shelf base they scavenge particles from the water and incorporate them into the growing basal ice. The resulting marine ice can be ~100 m thick; it differs from sea ice in that it is clear, desalinated, and bubble‐free. Icebergs of marine ice vary in color from blue to green, depending on the nature and abundance of foreign constituents in the seawater that became trapped in the ice as it grew. A red or yellow material (i.e., one that absorbs blue light), in combination with the blue of ice, can shift the wavelength of minimum absorption to green. Previously, dissolved organic carbon (DOC) had been proposed to be responsible for the green color. Subsequent measurements of low DOC values in green icebergs, together with the recent finding of large concentrations of iron in marine ice from the Amery Ice Shelf, suggest that the color of green icebergs is caused more by iron‐oxide minerals than by DOC. These icebergs travel great distances from their origin; when they melt they can deliver iron as a nutrient to the Southern Ocean.
