Lead-cooled fast reactors have multilayered designs and large internal temperature differences, which cause challenges in simulating reactor physics. SuperMC, a large-scale integrated software system for neutronics design, is inherently able to address complex geometries and multi-temperature problems. The purpose of this study is to verify the applicability of SuperMC to the lead-bismuth-cooled fast reactor RBEC-M. The multi-temperature cross-section generation function of SuperMC was employed and showed good performance. Based on the ENDF/B-VII.1 library, the effective multiplication factor keff obtained by SuperMC showed good agreement with those from previous works. The relationship of keff and 15N enrichment applied to the fuel material was also studied, with the results showing that in creased 15N could significantly improve keff. The axial power profile and kinetics parameters for the bench mark were then calculated and analyzed. This work thus verified the applicability of SuperMC for comprehensive neutronics simulations for lead-bismuth-cooled fast reactors.

Purpose The purpose of this paper is to investigate the effects of values of materialism on cognitive and affective impulsiveness and responsible financial behavior among young adults. Design/methodology/approach A large-scale study (n = 483) was conducted on a sample of young adults 18 to 25 years of age in Croatia. Findings The research found that materialism has no direct effect on responsible financial behaviour (RFB), however, cognitive impulsiveness fully mediates the relationship of all three there three elements of materialism, centrality, success and happiness and RFB. Affective impulsiveness has no effect on the relationship. Furthermore, only materialism as centrality strongly and positively influences cognitive and affective impulsiveness. Practical implications Presented conclusions could be used by policymakers as guidelines for developing educational plans and curriculum to build financial capability and consumer protection among young adults and could be helpful for brand management activities targeting young people purchase decisions. Originality/value This paper’s ultimate purpose is to uncover the mechanism and the power of materialism on impulsiveness and responsible financial behavior. The paper’s originality is established by the focus on the investigation of materialism as an antecedent factor of impulsiveness and by questioning the nature of the relationship between materialism and responsible financial behavior through the mediating effect of impulsiveness.

This study examines the connection between governance, financial performance, and financial difficulties of 27 conventional private banks during the pe3riod of 2015-2018. In order to meet the accuracy of the model in the regression analysis, the Lagrange Multiplier test was previously performed so that the Fixed Effects model was chosen. The relationship of insider ownership with ROA tends to be in the shape of inversed-U and the relationship between institutional ownership and ROA is significantly positive. The relationship between ROA and financial difficulties is significantly negative. Older or established large scale banks tend to have high ROA. This happens because the greater the assets, the healthier the cash flow of the bank, so that the potential for return of asset is quite high and financial difficulties tend to be low or avoidable.

In the decade and a half since economic liberalization began in Jordan, a little noticed but large-scale organizing trend has taken over the formal provision of social welfare, redefining the institutional conception of familial identity in the process. For over one third of the population, kin solidarities have been reorganized, formalized, and registered as nongovernmental organizations in an attempt to cope with the removal of basic social provisioning by the state. Although kinship clearly has been a major element in Jordan's history, the present phenomena alter traditional familial institutions, change kin lineages, and institutionalize the economic salience of family relations. In turn, the relationship of the populace to the state has changed, marginalizing previously regime-supporting groups and facilitating the implementation of economic neoliberalism without significant protest. Repackaged as charitable elements of civil society, these family associations are sanctioned and encouraged by the state and international community. Although they are not regime creations, family associations reinforce the Jordanian regime's efforts at political deliberalization. The new elites who head the organizations have been placated through indirect incorporation into the regime; they now wield significant economic power over fellow kin and have enhanced social status backed by the new group. Furthermore, the trend mainly consists of families without immediate ambitions of entering national politics. These are not the traditional elite families.

A large-scale, community-based survey was done to assess the frequency of a wide variety of sexual behaviors in normal preadolescent children and to measure the relationship of these behaviors to age, gender, and socioeconomic and family variables. A sample of 880 2-through 12-year-old children screened to exclude those with a history of sexual abuse were rated by their mothers using several questionnaire measures. The frequency of different behaviors varied widely, with more aggressive sexual behaviors and behaviors imitative of adults being rare. Older children (both boys and girls) were less sexual than younger children. Sexuality was found to be related to the level of general behavior problems, as measured by the Achenbach Internalizing and Externalizing T scores and to a measure of family nudity. It was not related to socioeconomic variables.

Equilibrium and kinetics parameters have been evaluated at 25.0 °C for the heterogeneous catalysis of atrazine hydrolysis in slurries of a chemically characterized mineral soil. The fraction of acidic sites that accounts for sorption capacity, and the sorption equilibrium function resemble those for humic acid and organic soil. Sorption and desorption half-lives increased with increasing coverage of sorption sites. The sorption half-lives ranged from 3.6 to 735 days. The desorption half-lives ranged from 1 to 11 days. The hydrolysis half-lives ranged from 9.6 to 168 days and are consistent with Brönsted acid catalysis theory. The relationship of independent variables to data scatter has been analyzed. The information obtained should be useful for water and solute transport models.

Gold mineralization on the Marn property, Yukon, occurs in two pyroxene skarn bodies, which are adjacent to the Mount Brenner Stock in the Ogilvie Mountains. The skarns are separated by a 600 m wide monzonite intrusion and show contrasting mineralogical and geochemical characteristics in addition to quite different metal values. Significant but uneconomic Au, Ag, W, and Cu mineralization is found in skarn on the north side of the intrusion, while very low Au grades (0.052 g/t) occur at the southern contact. The mineral assemblages of both skarns are dominated by iron-rich pyroxenes. The iron content of the pyroxenes varies between Hd40 and Hd80 in the northern location and Hd80 and Hd100 in the southern skarn. A well-developed sequence of retrograde alteration affected only the northern skarn. This was probably the result of porosity and permeability differences in the early, high-temperature pyroxene skarn, which permitted greater fluid–rock interaction in the northern skarn during cooling. A small volume of diopsidic, aluminous, wollastonite-bearing skarn occurs in both the northern and southern localities. The relationship of this type of skarn to the hedenbergitic skarn is ambiguous, since there is no large-scale mineralogical zoning. The Marn is similar to hedenbergitic, auriferous skarns of Japan, where the oxidation state of the intrusive rocks is believed to be the controlling factor in the development of skarn mineralogy.

The importance of the Clear Fork Focus as a pre-pottery archaeological complex of north-central Texas has become generally known to archaeologists through the industry of its discoverer and principal proponent, Dr. Cyrus N. Ray, of Abilene, Texas. Unfortunately, the relationship of this complex to other and comparable archaeological cultures of Texas has been largely neglected and some regrettable misinformation in regard to its chronological position has been widely disseminated. In this paper the cultural affiliations and age of the Clear Fork Focus will be discussed in terms of the evidence presented by its discoverers and from the standpoint of new data derived from large scale excavations completed by the University of Texas in the terraces of the Colorado River near Austin, Texas. Additional information obtained by the writer through study of some twelve thousand projectile points from central, south, and western Texas, and their geographic and temporal distribution also is used.

The relationship of the metopes to the architecture of the peristasis of the Hephaisteion and the Parthenon is examined in order to ascertain the extent of planning which took place before the erection of a Classical Greek temple. All relevant published measurements are taken into consideration and critically compared. On the basis of the discrepancies of the corresponding architectural and sculptural members, it is argued that the working-out of the details of the plan was not the result of large-scale drawings, but was affected after the commencement of construction. While the Hephaisteion is built largely in accordance with the conventions of a Classical Doric temple, the Parthenon, due to its unique plan, provides indications of experimentation inferred from the extensive inconsistencies at its eastern end.
