AbstractThis study evaluated the effect of gestational low protein diet (LPD) and/or postnatal bisphenol A (BPA) exposure on mammary gland development and carcinogenesis in female offspring. Pregnant Sprague‐Dawley rats were fed a normal protein diet (NPD, 17% protein) or LPD (6% protein). At weaning, female offspring were distributed in four groups (NPD, LPD, NPD + BPA, and LPD + BPA) and received vehicle or BPA in drinking water (0.1%), during postnatal day (PND) 21 to 51. On PND 51, some female offspring were euthanized or received a single dose of 7,12‐dimethylbenzoanthracene (DMBA, 30 mg/kg, i.g.) and were euthanized on PND 250. On PND 51, neither gestational LPD nor postnatal BPA exposure, individually or in combination, significantly altered the development of mammary gland tree, mean number of terminal structures or estrogen receptor beta (ER‐β), proliferating cell nuclear antigen (PCNA) or caspase‐3 protein expression in the mammary tissue. A significant reduction in mammary epithelial area (%) was observed in both LPD groups and a significant increase in ER‐α protein expression was detected only in LPD group. In LPD + BPA group was observed a significant increase in both fat pad area (%) and in mean number of mammary epithelial cells positive for progesterone receptor (PR). On PND 250, the groups that received BPA presented lower latency and higher tumor incidence and tumor multiplicity and LPD + BPA group more aggressive tumors. These findings suggest that postnatal BPA exposure associated with gestational LPD is able to induce morphological changes in the mammary gland and increase susceptibility to mammary carcinogenesis.

AbstractMany studies have found that married people have higher subjective well-being than those who are not married. Yet the increase in cohabitation raises questions as to whether only marriage has beneficial effects. In this study, we examine differences in subjective well-being between cohabiting and married men and women in midlife, comparing the United Kingdom, Australia, Germany, and Norway. We apply propensity score–weighted regression analyses to examine selection processes into marriage and differential treatment bias. We find no differences between cohabitation and marriage for men in the United Kingdom and Norway, and women in Germany. However, we do find significant differences for men in Australia and women in Norway. The differences disappear after we control for selection in Australia, but they unexpectedly persist for Norwegian women, disappearing only when we account for relationship satisfaction. For German men and British and Australian women, those with a lower propensity to marry would benefit from marriage. Controls eliminate differences for German men, although not for U.K. women, but relationship satisfaction reduces differences. Overall, our study indicates that especially after selection and relationship satisfaction are taken into account, differences between marriage and cohabitation disappear in all countries. Marriage does not lead to higher subjective well-being; instead, cohabitation is a symptom of economic and emotional strain.

Published: July 2019

AbstractOrganic pollutants are widespread and a known problem for the environment. p-nitrophenol (PNP) is one such pollutant found in effluents from various industries involved with pesticides, pharmaceuticals, petrochemicals, plastic, paper, and other materials. The objective of this research was to prepare and test organically modified clays using four different surfactants and to evaluate the removal efficiency of PNP from aqueous solutions. Organically modified clays have attracted great interest due to their wide applications in industry and environmental protection as sorbents for organic pollutants. Two natural smectite-dominated clay types from outcrops in Latvia and Lithuania as well as industrially manufactured montmorillonite (Mt) clay were modified using different nonionic (4-methylmorpholine N-oxide (NMO) and dimethyldodecylamine N-oxide (DDAO)) and cationic (benzyltrimethyl ammonium chloride (BTMAC) and dodecyltrimethyl ammonium chloride (DTAC)) surfactants. Modified clay materials were characterized by Fourier-transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and the Brunauer-Emmett-Teller method (BET) for surface area analysis. Sorption of PNP was investigated under various conditions, e.g. surfactant loading, initial PNP concentration, contact time, and pH. The novelty of the present study was to prepare innovative organo-sorbents based on manufactured as well as natural clay samples using cationic surfactants and nonconventional nonionic surfactants as modifiers. The sorption data combined with FTIR and XRD supplementary results suggests that nonionic organo-clay (Mt-DDAO_2) is the most effective sorbent and may serve as a low-toxicity immobilizer of pollutants such as phenols.

Published: July 2019

ABSTRACT:Background:MR perfusion imaging is a relatively new technique that may aid in identifying recurrent tumor (RT) in those with radically treated high-grade gliomas (HGG). We aim to assess the relationship between dynamic susceptibility contrast-enhanced MR perfusion (DSC-MRP) and overall survival to establish a baseline for future research and to determine the utility of DSC-MRP as a clinical decision-making and prognostic tool.Methods:We conducted a retrospective cohort study. Adults with pathologically confirmed HGG at the Juravinski Cancer Centre, Ontario between January 2011 and April 2014 with at least one post-treatment DSC-MRP were included. DSC-MRP was interpreted as positive or negative for tumor recurrence by experienced radiologists. The primary outcome was overall survival.Results:Sixty-one patients were enrolled. Median survival for patients with a positive DSC-MRP scan was 4.5 months compared with 10.2 months for those with a negative DSC-MRP scan (hazard ratio [unadjusted] = 2.51; 95% confidence interval = 1.10–5.67; p-value = 0.03). Multivariable modeling (adjusted) that included all pre-selected variables showed similar results.Conclusion:Survival time in patients with HGG is generally low, and almost all patients will demonstrate RT. Our data suggest a positive DSC-MRP correlates with lower overall survival and may signify the presence of highly active RT. These results generate a hypothesis that there may be a prognostic role for the use of serial DSC-MRP for tumor surveillance. More importantly, this biomarker may aid in decision making for treatment plans and palliation.

Published: July 2019

ABSTRACTIn November 2017, a disruptive earthquake occurred in Western Iran. After the major earthquake in Kermanshah, most affordable buildings such as a hospital in Islamabad and a dozen schools were destroyed. According to experts, a dangerous location (construction on the fault), poor quality of concrete, inappropriate connection of the facade to the structure, the use of undesirable construction materials, and low quality of non-structural components are considered as the main reasons for these damages. Regarding the role of government in the developing countries, construction policies should be modified and new policies should be implemented to enhance the structural and non-structural resilience in the buildings.

AbstractRecent studies have increasingly suggested leadership as a major antecedent to corporate social responsibility (CSR), empirical studies, which investigated the influence of various leadership aspects such as style and ethics on CSR and unraveled the mechanism through which leadership exerts its impact on CSR were restricted. Thus, the purpose of this research was to study the relationship between CEO ethical leadership and CSR by focusing on the mediating role of ethical culture and the intellectual capital facets (human capital and social capital) of the organization. Data for current research were collected through personally administered questionnaire through survey. Based on a sample of 250 respondents, the current study instituted that CEO ethical leadership positively affected CSR. Intellectual capital facets (human and social) and organizational ethical culture were observed to have a mediating effect on CEO ethical leadership and CSR relationship. Practical implications of the results are also given in the current study. Moreover, study limitations and directions for future study have also been presented.

AbstractAge and growth of the little Indian squid Loliolus hardwickei (Gray, 1849) were studied using samples collected in the coastal waters of Arabian Sea. Statolith increment counts demonstrated that L. hardwickei has a fast growth rate (dorsal mantle length: 0.31–0.73 mm day−1 in females and 0.27–0.56 mm day−1 in males) and a short lifespan of less than 6 months. Females are the larger sex and their daily growth rates were higher than in males. The oldest male and female were 110 and 130 days old; the youngest mature female and male were 62 and 52 days old respectively. The oviducal fecundity ranged from 104–480 eggs, mean = 360 eggs (14–23 eggs g−1 body weight).
Do bilingual children lag behind? A study of morphological encoding using ERPs
Authors: CLAHSEN Harald , JESSEN Anna 
Published: July 2019

AbstractThe current study investigates how bilingual children encode and produce morphologically complex words. We employed a silent-production-plus-delayed-vocalization paradigm in which event-related brain potentials (ERPs) were recorded during silent encoding of inflected words which were subsequently cued to be overtly produced. The bilingual children's spoken responses and their ERPs were compared to previous datasets from monolingual children on the same task. We found an enhanced negativity for regular relative to irregular forms during silent production in both bilingual children's languages, replicating the ERP effect previously obtained from monolingual children. Nevertheless, the bilingual children produced more morphological errors (viz. over-regularizations) than monolingual children. We conclude that mechanisms of morphological encoding (as measured by ERPs) are parallel for bilingual and monolingual children, and that the increased over-regularization rates are due to their reduced exposure to each of the two languages (relative to monolingual children).
Acknowledgment Deeds (iqrārs) in Early New Persian from the Area of Bāmiyān (395–430ah/1005–1039ce)
Authors: HAIM OFIR 
Published: July 2019

AbstractThe article provides an edition and translation of eight early Islamic acknowledgment(iqrār)deeds written in Early New Persian, which are preserved in the National Library of Israel. The acknowledgment deeds are part of a rich trove of manuscripts known as the “Afghan Genizah”, reportedly found in the area of Bāmiyān in central Afghanistan. Dated between the years 395–430/1005–1039, the eight discussed acknowledgment deeds are probably the earliest extant legal documents written in New Persian. This implies that Islamic legal documents were drawn up in New Persian in the area of Bāmiyān—and perhaps in other eastern Iranian territories—as early as the beginning of the 5th/11thcentury. Furthermore, a thorough examination of the formulaic structure of these acknowledgment deeds reveals their reliance on Arabic legal formulae, which may reflect an early stage of legal writing in New Persian.

Published: July 2019

AbstractIn the context of the negative consequences of psychological abuse, a scale was developed to specifically assess the emotional disturbances in individuals who had experienced abusive behaviors over a period of time within a cultic group. The Emotional Distress Scale in Survivors of Abusive Groups (EDS-SAG) was administered, along with other relevant measures of group psychological abuse and psychopathological symptoms, to 706 Spanish-speaking former members of different groups, distributed into two samples according to whether they had experienced group psychological abuse (n = 413) or not (n = 293). Analyses supported a unidimensional structure of the 18 items on the EDS-SAG, explaining 50.7% of the total variance. This factorial solution was found to be stable when the sample of victims was split by sex and by the age of involvement in the group. Results also showed adequate reliability of the scores and significant associations between the scores on the EDS-SAG and the scores on measures of group psychological abuse (PAEGS: .86, p &lt; .001) and psychopathological symptoms (BSI: .30, p &lt; .001; PTCI: .46, p &lt; .001). The results obtained reveal that this new scale is a suitable tool for measuring emotional distress in Spanish-speaking survivors of abusive groups. In the research field, it would be possible to evaluate the antecedents of emotional distress or their protective factors. In applied contexts, it would be possible to rigorously evaluate the emotional difficulties of abuse victims, allowing a better diagnosis and therapeutic approach. All of this will contribute to the assessment and understanding of the long-term consequences of group psychological abuse.
Recurrent Snowmelt Pattern Synthesis Using Principal Component Analysis of Multiyear Remotely Sensed Snow Cover
Authors: Woodruff Craig D. , Qualls Russell J. 
Published: July 2019

AbstractSnow acts as a vital source of water especially in areas where streamflow relies on snowmelt. The spatiotemporal pattern of snow cover has tremendous value for snowmelt modeling. Instantaneous snow extent can be observed by remote sensing. Cloud cover often interferes. Many complex methods exist to resolve this but often have requirements which delay the availability of the data and prohibit its use for real‐time modeling. In this research, we propose a new method for spatially modeling snow cover throughout the melting season. The method ingests multiple years of MODerate Resolution Imaging Spectroradiometer snow cover data and combines it using principal component analysis to produce a spatial melt pattern model. Development and application of this model relies on the interannual recurrence of the seasonal melting pattern. This recurrence has long been accepted as fact but to our knowledge has not been utilized in remote sensing of snow. We develop and test the model in a large watershed in Wyoming using 17 years of remotely sensed snow cover images. When applied to images from 2 years that were not used in its development, the model represents snow‐covered area with accuracy of 84.9–97.5% at varied snow‐covered areas. The model also effectively removes cloud cover if any portion of the interface between land and snow is visible in a cloudy image. This new principal component analysis method for modeling the interannually recurring spatial melt pattern exclusively from remotely sensed images possesses its own intrinsic merit, in addition to those associated with its applications.

AbstractFrom 17–22 August 2017 simultaneous enhancements of ammonia (NH3), carbon monoxide (CO), hydrogen cyanide (HCN), and ethane (C2H6) were detected from ground‐based solar absorption Fourier transform infrared (FTIR) spectroscopic measurements at two high‐Arctic sites: Eureka (80.05°N, 86.42°W) Nunavut, Canada, and Thule (76.53°N, 68.74°W), Greenland. These enhancements were attributed to wildfires in British Columbia and the Northwest Territories of Canada using FLEXPART back‐trajectories and fire locations from Moderate Resolution Imaging Spectroradiometer (MODIS) and found to be the greatest observed enhancements in more than a decade of measurements at Eureka (2006–2017) and Thule (1999–2017). Observations of gas‐phase NH3 from these wildfires illustrate that boreal wildfires may be a considerable episodic source of NH3 in the summertime high Arctic. Comparisons of GEOS‐Chem model simulations using the Global Fire Assimilation System (GFASv1.2) biomass burning emissions to FTIR measurements and Infrared Atmospheric Sounding Interferometer (IASI) measurements showed that the transport of wildfire emissions to the Arctic was underestimated in GEOS‐Chem. However, GEOS‐Chem simulations showed that these wildfires contributed to surface layer NH3 and NH
enhancements of 0.01–0.11 ppbv and 0.05–1.07 ppbv, respectively, over the Canadian Archipelago from 15–23 August 2017.

AbstractDissimilatory nitrate/nitrite reduction processes play an important role in controlling nitrogen loading in river environments. However, the relative importance of climatic temperature regime and biogeochemical controls to dissimilatory nitrate/nitrite reduction processes remains unclear. We used nitrogen isotope tracer approach to investigate geographical variabilities of denitrification, anaerobic ammonium oxidation (anammox), and dissimilatory nitrate reduction to ammonium (DNRA) in river sediments from temperate to tropical climates of China. Denitrification, anammox, and DNRA varied greatly across the climatic gradient, with potential rates of 1.47–25.7, 0.54–3.4, and 0.15–7.17 nmol N g−1 h−1, respectively. Mean measured rates throughout the sampling sites were 9.73 nmol N g−1 h−1 for denitrification, 1.29 nmol N g−1 h−1 for anammox, and 1.61 nmol N g−1 h−1 for DNRA. Denitrification and DNRA rates increased significantly from temperate to tropical climates, while no significantly spatial difference was observed for anammox rates along the climatic gradient. Mean annual temperature, total organic carbon, dissolved organic carbon, pH, NH4+, NO3–, C/N, Fe2+, and functional genes were the crucial factors affecting denitrification, anammox, and DNRA. High dissolved organic carbon and NO3– availability determined nitrogen removal capacity in river sediments. Mean annual temperature was the most important factor explaining the geographical variances of denitrification and DNRA, while the critical predictor of anammox variance was sediment pH along the climatic gradient. Our results highlight that biogeochemical controls and climatic temperature regime are important coregulators affecting the geographical variabilities of dissimilatory nitrate/nitrite reduction processes in river sediments at the continental‐scale variation.
Statistical Analysis of the Correlation Between Anomalies in the Czech Electric Power Grid and Geomagnetic Activity
Authors: Výbošt’oková Tatiana , Švanda Michal 
Published: July 2019

AbstractEruptive events on the Sun have an impact on the immediate surroundings of the Earth. Through induction of electric currents, they also affect Earth‐bound structures such as the electric power transmission networks. Inspired by recent studies we investigate the correlation between the disturbances recorded in 12 years in the maintenance logs of the Czech electric power distributors with the geomagnetic activity represented by the K index. We find that in case of the data sets recording the disturbances on power lines at the high and very high voltage levels and disturbances on electrical substations, there is a statistically significant increase of anomaly rates in the periods of tens of days around maxima of geomagnetic activity compared to the adjacent minima of activity. There are hints that the disturbances are more pronounced shortly after the maxima than shortly before the maxima of activity. Our results provide indirect evidence that the geomagnetically induced currents may affect the occurrence rate of anomalies registered on power‐grid equipment even in the midlatitude country in the middle of Europe. A follow‐up study that includes the modeling of geomagnetically induced currents is needed to confirm our findings.
