Dynamics of the Employment Assimilation of First-Generation Immigrant Men in Sweden: Comparing Dynamic and Static Assimilation Models with Longitudinal Data [PDF]

open access: yes
We analyse the dynamics of employment assimilation of first-generation immigrant men in Sweden using a high-quality, register-based panel data set. It is discussed that when there are significant differences between employment status persistence of ...

Optimising Sulphur Fertilisation in Ryegrass–White Clover Swards Reduces Leached Nitrate Nitrogen Losses, While Increasing Plant Yield and Nitrogen Off‐Take

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
The inclusion of sulphur at two inorganic nitrogen rates (0 and 150 kg N ha−1) improves plant productivity in a ryegrass–white clover sward and reduces nitrate‐N loss to groundwater in a free‐draining sandy loam soil. ABSTRACT Background Reducing nitrogen (N) losses to water, lessening reliance on inorganic fertiliser and maintaining agricultural ...

Intra‐Plant Nitrogen Isotope Fractionation in Maize

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aim The natural abundance of nitrogen isotopes (δ15N) provides a powerful integrative tracer of nitrogen uptake and assimilation in plants, yet the internal partitioning of δ15N among plant tissues remains insufficiently understood.

Effects of Microplastic Pollution on Growth, Photosynthesis, and Nutritional Composition of Maize (Zea mays L.)

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Microplastic (MP) contamination in agroecosystems is an increasingly recognized environmental concern, whereas its polymer‐specific impacts on plant growth and nutritional composition remain poorly understood. Aim Our study aimed to evaluate how polymer type and concentration of MPs directly affect plant growth, physiological traits,

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Synergistic effects of maize defoliation and common bean relay cropping in Western Ethiopia

open access: yesJSFA reports, EarlyView.
Abstract Background Maize defoliation is practiced to enhance crop management by improving light penetration, nutrient allocation, controlling weeds, and providing supplementary feeds for livestock. A rapid decline in soil fertility and low crop yields associated with maize‐based monocropping has prompted the recent introduction of maize common bean ...

Effect of heavy metal stress in plant metabolism of solanaceous plant species with emphasis on nitrogen assimilation [PDF]

open access: yes, 2011
Several plant species are able to accumulate and withstand large quantities of heavy metals in their tissues without dramatic alterations in their growth usually observed in plants. Such metal accumulating plants are tested and used for remediation of
