Irrigation and Drainage, EarlyView.ABSTRACT Irrigation scheduling is crucial for ensuring precise water delivery to crops. However, in many sub‐Saharan African irrigation schemes, water is applied without considering crop water needs, resulting in low crop water productivity and low yields. Solar‐powered irrigation systems can automatically meet these needs by utilizing solar radiation,

Devastating Rio Doce mining disaster sends shockwaves through earthworm populations
Journal of Environmental Quality, EarlyView.Abstract The Fundão dam breach is considered one of the most severe environmental mining disasters globally, causing widespread changes to the soils of the Rio Doce watershed, one of Brazil's most important catchments. Given the ecological importance of earthworms to soil structure and dynamics, we investigated the richness, abundance, and biomass of ...

Orthodontic movement in deciduous teeth [PDF]
Dental Press Journal of Orthodontics, 2015 Deciduous teeth exfoliate as a result of apoptosis induced by cementoblasts, a process that reveals the mineralized portion of the root while attracting clasts. Root resorption in deciduous teeth is slow due to lack of mediators necessary to speed it up; however, it accelerates and spreads in one single direction whenever a permanent tooth pericoronal ...

Defining stream riparian zones across multidimensional environmental gradients
Journal of Environmental Quality, EarlyView.Abstract Riparian zones are a critical terrestrial‐aquatic ecotone. They play important roles in ecosystems including (1) harboring biodiversity, (2) influencing light and carbon fluxes to aquatic food webs, (3) maintaining water quality and streamflow, (4) enhancing aquatic habitat, (5) influencing greenhouse gas production, and (6) sequestering ...

Bilateral fusion of permanent maxillary incisors
Indian Journal of Dental Research, 2011 Dental fusion is a rare developmental anomaly, which is included in the anomalies of tooth morphology or shape. Fusion can occur at the level of enamel or enamel and dentin, which results in the formation of a single tooth with enlarged clinical crown ...

Accommodation of Dental Variations During Jaw Growth in Ungulate Mammals
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.Using geometric morphometrics, we compared the covariation pattern of the dentition and the palate during growth in 23 ungulate species. ABSTRACT The growth of teeth and jaw bones is intimately linked in vertebrates, especially in mammals due to their specialized dentition and limited body growth.

Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Over half of global soil organic carbon (SOC) stocks are stored in subsoil. A larger fraction of carbon (C) input may be retained and stabilized in subsoil as compared to topsoil. This retained fraction determines C sequestration efficiency, which may also depend on the amount of C input.
