Strip-till as a means of decreasing spatial variability of winter barley within a field scale

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019
The tillage system, which joins soil tillage, fertilisation, and seed sowing in one pass of a machine, is rarely used in cereal cultivation. This research aimed to study whether strip-till and conventional tillage (post-harvest ripping and mixing of ...

Empirical Evidence for Decreasing Returns to Scale in a Health Capital Model [PDF]

SSRN Electronic Journal, 2012
We estimate a health investment equation, derived from a health capital model that is an extension of the well-known Grossman model. Of particular interest is whether the health production function has constant returns to scale, as in the standard Grossman model, or decreasing returns to scale, as in the Ehrlich-Chuma model and extensions thereof.

Decreased attention to object size information in scale errors performers [PDF]

Infant Behavior and Development, 2017
Young children sometimes make serious attempts to perform impossible actions on miniature objects as if they were full-size objects. The existing explanations of these curious action errors assume (but never explicitly tested) children's decreased attention to object size information.

The decreasing wind speed in southwestern China during 1969-2009,and possible causes [PDF]

, 2012
Daily wind speed data from 110 stations in southwestern China were analyzed to determine trends,spatial differences and possible causes. There was a statistically significant decrease of 0.24 m/s per decade in the annual mean wind speed during the period

Standardized Water Budget Index and Validation in Drought Estimation of Haihe River Basin, North China

Advances in Meteorology, 2016
The physical-based drought indices such as the self-calibrated Palmer Drought Severity Index (sc-PDSI) with the fixed time scale is inadequate for the multiscalar drought assessment, and the multiscalar drought indices including Standardized ...

Effect of a Scale‐Aware Convective Parameterization Scheme on the Simulation of Convective Cells‐Related Heavy Rainfall in South Korea

Journal of Advances in Modeling Earth Systems, 2022
In this study, the effect of a scale‐aware convective parameterization scheme (CPS) on the simulation of heavy precipitation in the gray‐zone was investigated using the Weather Research and Forecasting (WRF) model.

Development characteristics of multi-scale fracture network systems in metamorphic buried hills

Frontiers in Earth Science, 2023
Natural fractures are regarded as important reservoir spaces and effective seepage channels at metamorphic buried hills. Continuous networks associated with multi-scale fractures with good connectivity is critical for high-quality reservoirs as well as ...

Biotic homogenization can decrease landscape-scale forest multifunctionality [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance Numerous studies have demonstrated the importance of biodiversity in maintaining multiple ecosystem functions and services (multifunctionality) at local spatial scales, but it is unknown whether similar relationships are found at larger spatial scales in real-world landscapes.

Estimating the return to scale of an integer-valued data envelopment analysis model: efficiency assessment of a higher education institution

Arab Journal of Basic and Applied Sciences, 2019
The integer radial data envelopment analysis (IDEA) approach has been introduced by numerous efficiency studies to accurately measure various real life applications where some of their inputs and/or outputs are restricted to integer values.
