Soil displacement and soil bulk density changes as affected by tire size [PDF]

open access: yes, 2013
The selection of the appropriate tire size and inflation pressure for a particular load and soil condition is a critical consideration to ensure that the effects of vehicle traffic on soil compaction are minimized and that agricultural soils are managed ...

Physical properties of kernels from modern maize hybrids used in Croatia [PDF]

open access: yesJournal of Central European Agriculture, 2020
The physical properties of maize are a result of kernel structure, they indicate chemical properties of the kernel, and hence, its nutritive value. This research aimed to explore the physical traits of kernels of 80 commercial maize hybrids from nine ...

Modeling the Impact of Rhizosphere Bulk Density and Mucilage Gradients on Root Water Uptake

open access: yesFrontiers in Agronomy, 2021
In models of water flow in soil and roots, differences in the soil hydraulic properties of the rhizosphere and the bulk soil are usually neglected. There is, however, strong experimental evidence that rhizosphere and bulk soil hydraulic properties differ

Soil compaction caused by 450C Timber Jack wheeled skidder (Shefarood forest, northern Iran)

open access: yesJournal of Forest Science, 2007
In forest harvesting operations usually after using skidding machinery (skidders), traces of soil damage in the form of soil compaction and wheel and logs ruts can be seen in the forest soil. Soil bulk density, which represents soil compaction, decreases

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

Optical Properties of Neutral F Centers in Bulk MgO with Density Matrix Embedding [PDF]

open access: yes, 2023
The optical spectra of neutral oxygen vacancies ($F^0$ centers) in the bulk MgO lattice was investigated using density matrix embedding theory. The impurity Hamiltonian was solved with the complete active space self-consistent field (CAS-DMET) and second-

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...
