Histological evaluation of pulp tissue from second primary molars correlated with clinical and radiographic caries findings

Dental Research Journal, 2014
Background: Managing dental caries in young children is demanding due to the elusions present on the right diagnostic criteria for treatment. The present study evaluated the histological status of pulp tissues extracted from primary second molar with ...

Multidecadal Changes and Interannual Variation in Springtime Phenology of North American Temperate and Boreal Deciduous Forests

Geophysical Research Letters, 2018
The timing of leaf emergence is an important diagnostic of climate change impacts on ecosystems. Here we present the first continental‐scale analysis of multidecadal changes in the timing of spring onset across North American temperate and boreal forests

Human–Wildlife Conflict or Human–Human Conflict? Social Constructions of Stakeholder Groups Involved in Wildlife Management in Northern Zimbabwe 人兽冲突抑或人际冲突？津巴布韦北部野生动物管理之利益相关方的社会建构研究

Integrative Conservation, EarlyView.
The study investigated how stakeholder groups involved in wildlife management constructed images of each other. Stakeholder groups socially constructed each other as: powerful outsiders; ignorant and inconsiderate; habitat destroyers and poachers; and uncaring, greedy and selfish.

Long-term experimental warming and nutrient additions increase productivity in tall deciduous shrub tundra

, 2014
Warming Arctic temperatures can drive changes in vegetation structure and function directly by stimulating plant growth or indirectly by stimulating microbial decomposition of organic matter and releasing more nutrients for plant uptake and growth.

Can Solar‐Powered Irrigation Systems Naturally Meet Crop Water Requirements? Proof of Concept From a Case Study in Sub‐Saharan Africa

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,

Variability of radio signal attenuation by single deciduous tree versus reception angle at 80 GHz [PDF]

2025 19th European Conference on Antennas and Propagation (EuCAP), Stockholm, Sweden, 30 Mar.-4 Apr. 2025, pp. 1-5
Vegetation significantly affects radio signal attenuation, influenced by factors such as signal frequency, plant species, and foliage density. Existing attenuation models typically address specific scenarios, like single trees, rows of trees, or green spaces, with the ITU-R P.833 recommendation being a widely recognized standard.

Utility of near‐surface phenology in estimating productivity and evapotranspiration across diverse ecosystems

Journal of Environmental Quality, EarlyView.
Abstract Agroecosystems, which include row crops, pasture, and grass and shrub grazing lands, are sensitive to changes in management, weather, and genetics. To better understand how these systems are responding to changes, we need to improve monitoring and modeling carbon and water dynamics.
