<em>This article describes the principles of developing a structural model of the concept. Semantic structure is determined by a comprehensive analysis of dictionary definitions and scientific tokens, which calls the concept. The differences between the objectification of the concept of lexical and phraseological units are indicated. The author draws attention to the need for analysis of internal forms of phraseology, which are the carriers of ethnic and cultural information. This article contains comments on the concept of dividing the structure into the nucleus - the propositional zone and t

Abstract:

The rheology of the metamorphosed oceanic crust may be a critical control on megathrust strength and deformation style. However, little is known about the strength and deformation style of metamorphosed basalt. Exhumed megathrust shear zones exposed on Kyushu, SW Japan, contain hydrous metabasalts deformed at temperatures between ~300° and ~500°C, spanning the inferred temperature-controlled seismic-aseismic transition. Field and microstructural observations of these shear zones, combined with quartz grain-size piezometry, indicate that metabasalts creep at shear stresses <100 MPa at ~370°C

Abstract The meridional mode provides a source of predictability for the tropical climate variability and change on seasonal and longer time scales by transporting extratropical climate signals into the tropics. Previous research shows that the tropical imprint of the meridional mode is constrained by the interhemispheric asymmetry of the tropical mean climate state. In this study the constraint of the zonal asymmetry is investigated in an AGCM thermodynamically coupled with an aquaplanet slab ocean model. The strategy is to modify the zonal asymmetry of the mean climate state and examine the

Weak zones in the lithosphere thicken and act as loads that pull down the lithosphere in regions around the weak zones. Strong zones are subjected to less lithospheric thickening than the surroundings and produce surface depressions and uplift in the surrounding areas. The model is used to study the Late Cretaceous and Paleocene differential vertical movements in the eastern North Sea area. The Sorgenfrei-Tornquist Zone is assumed to be a pre-

In northern U.S. vegetable cropping systems, attempts at no-till (NT) production have generally failed because of poor crop establishment and delayed crop maturity. Strip tillage (ST) minimizes these problems by targeting tillage to the zone where crops are planted while maintaining untilled zones between crop rows, which foster improvements in soil quality. ST has been shown to maintain crop yields while reducing energy use and protecting soils in vegetable crops, including sweet corn, winter squash, snap bean, carrot, and cole crops.

SUMMARY This study explores the geomorphological expression and geological context of a normal fault scarp in a stable continental region (SCR) which we interpret as having failed in large (Mw &gt;7) earthquakes. Records of such large normal faulting events in an SCR (or even in more rapidly deforming regions) are extremely rare, and so understanding this feature is of international interest. The scarp is exceptionally well-preserved due to the extensive calcrete/silcrete cementation. In areas where this cementation is reduced or absent the scarp is more diffuse, as expected for a feature

Abstract:

Fractures, which are related to tectonic activity and lithology, have a significant impact on the storage and production of oil and gas in shales. To analyze the impact of lithological factors on fracture development in shales, we selected the shale formation from the Da’anzhai member of the lower Jurassic shales in a weak tectonic deformation zone in the Sichuan Basin. We defined a lithology combination index (LCI), that is, an attribute quantity value of some length artificially defined by exploring the lithology combination. LCI contains information on shale content at a certain depth, the

Abstract:

Abstract A suite of high-resolution two-dimensional ensemble simulations are used to investigate the predictability of mountain waves, wave breaking, and downslope windstorms. For relatively low hills and mountains, perturbation growth is weak and ensemble spread is small. Gravity waves and wave breaking associated with higher mountains exhibit rapid perturbation growth and large ensemble variance. Near the regime boundary between mountain waves and wave breaking, a bimodal response is apparent with large ensemble variance. Several ensemble members exhibit a trapped wave response and others re

Using a sample of students ( N = 118) engaged in an 8-week project to build an e-book chapter, this study finds that cognitive absorption impacts interpersonal conflict and team performance. In particular, virtual teams with aggregated higher levels of focus immersion and temporal dissociation (dimensions of cognitive absorption) demonstrate higher levels of performance and interpersonal conflict. Furthermore, there is an interaction effect between focus immersion and temporal dissociation that moderates the impact on performance and interpersonal conflict. The teams with aggregated high level

The Mulcahy Gabbro (2.73 Ga) is an exceptionally well-preserved tholeiitic layered intrusion located in the Wabigoon Subprovince of the Superior Province. The intrusion has a 900 m thick marginal zone of weakly layered gabbronoritic cumulate rocks characterized by a trend of upward Mg-enrichment. The overlying 1100 m thick lower zone consists of well-layered cumulate rocks that display a prominent trend of upward Fe-enrichment. The order of appearance of cumulus minerals in the lower zone is orthopyroxene + plagioclase, augite, apatite, pigeonite, Fe-rich olivine, magnetite.The upward increase

Purpose: The aim of the study was to improve the hardness and tribological properties of austenitic 316L steel by laser alloying with boron and nickel. Design/methodology/approach: The relatively low wear resistance of austenitic 316L steel could be improved by an adequate surface treatment. Laser alloying was developed as an alternative for time- and energy-consuming thermo-chemical treatment, e.g. diffusion boriding. In the present study, laser alloying of 316L steel with boron and nickel was carried out as the two-stage process. Firstly, the outer surface of the sample was coated with the p

When climate was warm and humid, sea-level rose, the sedimentary environmental salinity increased and ability of element eluviate-leaching were weak, geochemical elements can not b

Abstract:

Aim: Many studies support an inverse relationship between benign prostate hypertrophy (BPH) size and incidence of prostate cancer (PCa), but the causal link between these conditions is poorly understood. Recent studies suggest that a growing transition zone (TZ) in the prostate may induce pressure on the outer peripheral zone (PZ), leading to atrophy of the glandular tissue where PCa often originates, providing a possible explanation for this interaction. To further investigate this phenomenon, our pilot study uses magnetic resonance imaging (MRI) to examine quantitative zonal changes in a con

This exploratory study investigated the experiences of seven bilingual school psychology graduate students’ participation in a two-week cultural immersion experience at the Texas–Mexico border. Findings revealed five significant themes related to their experience: (1) pushed out of comfort zone, (2) bonding with peers, (3) language, culture, and identity, (4) awareness of unique challenges, and (5) changes needed in the immersion program. Implications for school psychology programs and future research directions are discussed.

Abstract. Although many geophysical models have been proposed in the Longmenshan fault zone (LFZ) and its surrounding areas, the deep structure of the seismic gap and its constraint of the Wenchuan and Lushan earthquakes remain uncertain. Based on the compiled aeromagnetic data and Bouguer gravity data, we have tried to create a more detailed and reasonable magnetic and density model using 2D forward modeling and 3D inversion and made the deep structure of the LFZ visible. The research shows that structure is heterogenous across the LFZ. The earthquake epicenters are located in regions with hi

The total phosphorus (TP)–biomass relationship curves showed that the increment of biomass with TP is weak at high TP levels. The decrease in biomass at the high end of the curves might be a synthesis of the pattern of responses of the major taxonomic groups (except cyanobacteria) to environmental
