Biochar with nitrapyrin reduces ammonia volatilization and increases nitrogen use efficiency of cabbage: A 15N tracer study
Nitrogen use efficiency (NUE) in subtropical crop** systems is low causing a large quantity of reactive N loss to the environment. However, the mechanisms and pathways of such losses are poorly understood. T...

Open AccessTerbium-149 production: a focus on yield and quality improvement towards preclinical application
Terbium-149 (T1/2 = 4.1 h, Eα = 3.98 MeV (16.7%), 28 µm range in tissue) is a radionuclide with potential for targeted alpha therapy. Due to the negligible emission of α-emitting daughter nuclides, toxicity to he...

Open AccessThe effect of mycophenolate mofetil on podocytes in nephrotoxic serum nephritis
Mycophenolate mofetil (MMF) is applied in proteinuric kidney diseases, but the exact mechanism of its effect on podocytes is still unknown. Our previous in vitro experiments suggested that MMF can ameliorate p...

Open AccessComparison of surgical techniques for optimal lead placement in sacral neuromodulation: a cadaver study
Sacral neuromodulation (SNM) is a common treatment for patients with urinary and faecal incontinence. A close contact of the tined lead electrode with the targeted nerve is likely to improve functional outcome.

Open AccessLinking long-term soil phosphorus management to microbial communities involved in nitrogen reactions
The influence of soil phosphorous (P) content on the N-cycling communities and subsequent effects on N2O emissions remains unclear. Two laboratory incubation experiments were conducted on soils collected from a l...

Open AccessA dilatant, two-layer debris flow model validated by flow density measurements at the Swiss illgraben test site
We propose a dilatant, two-layer debris flow model validated by full-scale density/saturation measurements obtained from the Swiss Illgraben test site. Like many existing models, we suppose the debris flow con...

Herbivore-induced plant volatiles, not natural enemies, mediate a positive indirect interaction between insect herbivores
Many insect herbivores engage in apparent competition whereby two species interact through shared natural enemies. Upon insect attack, plants release volatile blends that attract natural enemies, but whether t...
