Mineral Fertilization and Maize Cultivation as Factors Which Determine the Content of Trace Elements in Soil

open access: yesAgronomy, 2022
This study has been carried out in order to determine the effect of increasingly intensive fertilization with potassium, applied in combination with nitrogen, on the content of trace elements in soil after the harvest of maize (Zea mays L.).

Simulating the long term impact of nitrate mitigation scenarios in apilot study basin [PDF]

open access: yes, 2013
The agro-hydrological model TNT2 was used to explore for a period of 14 years (1987–2001) the likelyconsequences of mitigation scenarios on nitrate contamination of the stream water in a small agriculturalcatchment.

Nitrogen Fertilization

open access: yesHortScience, 1987
Abstract In the Feb. 1987 issue of HortScience 22:34-36, I was interested in the paper by Charles A. Mullins entitled “Effects of Nitrogen Fertilization on Production of Mechanically Harvested Snap Beans”. However, I found that two very important items of significance were not given: The form of N applied was not given.

Poly(lactic‐co‐glycolic acid) Nanoparticles for IL‐12 Self‐Amplifying RNA Delivery in Glioblastoma Models

open access: yesAdvanced Functional Materials, EarlyView.
xxxx. ABSTRACT Glioblastoma (GBM) remains one of the most lethal brain cancers, with median survival rarely exceeding 15 months after diagnosis. Interleukin‐12 (IL‐12) is a potent immunostimulatory cytokine capable of reshaping the tumor microenvironment (TME), yet its clinical translation is hindered by systemic toxicity and short half‐life. RNA‐based
