Demands to Improvement of Mining Dump Truck Construction

open access: yesМеханика машин, механизмов и материалов, 2012
The paper analyzes the operationing conditions of the automobile transport in the open-pit minings. In the process of deepening open-pit minings steadily become more complex conditions of operation of mining dump trucks, which requires improvement of ...

Sustainable Hydrogel‐Forming Microneedle‐Reservoir Patches for Transdermal Delivery of Hydrophilic Macromolecules: Biopolymers, Green Manufacturing and Translation

open access: yesAdvanced Science, EarlyView.
Hydrogel‐forming microneedle (HFMN)‐reservoir patches provide a modular route for controlled transdermal delivery of hydrophilic biomacromolecules. The platform integrates skin‐barrier penetration, sustainable biopolymers, scalable green manufacturing, hydration‐driven transport, model‐cargo validation, and translational quality requirements.

Keeping Pace or Falling Behind? The Depth of Latin American Trade Agreements

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This article examines whether Latin American countries are keeping pace with global trends in trade agreement depth or falling behind. Using 681 agreements (1970–2019), we develop the Depth Index of Trade Agreements (DITA) to weight provisions endogenously through factor analysis based on co‐occurrence patterns.

Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Effects of AMF inoculation on accumulation of plant-soil nutrients and colonization of native DSE in eastern grassland opencast mining area

open access: yesMeitan xuebao
Different grasses in the eastern steppe have different proportions of living space, so the study on the relationship between the growth and competition of the grassland grasses is of great significance to reveal the 1ecological evolution of the grassland.

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

Spatial distribution of soil bulk density and its relationship with slope and vegetation allocation model in rehabilitation of dumping site in loess open-pit mine area

open access: yesEnvironmental Monitoring and Assessment, 2020
Studies of soil bulk density (BD) spatial variations of land reclaimed after mining have become a focus of land reclamation and ecological restoration research. However, there have been few studies on the relationship among the reconstructed BD, terrain conditions, and vegetation growth.

EBHIS Local Volume Galaxy Hi Survey (LVGHIS)

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Here, we present the “Local Volume Galaxy Hi Survey” (LVGHIS). It is based on the first data release of the Milky Way portion of the Effelsberg Bonn Hi‐Survey (EBHIS). We homogeneously measured the mass and dynamics of the local volume galaxies within the radial velocity limit of |vLSR|≤600kms−1$$ \mid {v}_{\mathrm{LSR}}\mid \le 600\kern0.6em \
