Effect of combined nitrogen on symbiotic nitrogen fixation in pea plants [PDF]
The nitrogen-fixing activity of the symbiotic system of Pisum sativum with Rhizobium leguminosarum is adversely affected by combined nitrogen. Both ammonium chloride and potassium nitrate, when added to the roots, lower the nitrogenase activity ...

ABSTRACT Post‐transplant cyclophosphamide (PT‐CY) remains the standard of care for graft‐versus‐host disease (GvHD) prophylaxis in haploidentical hematopoietic cell transplantation (HCT), yet relapse, delayed immune reconstitution, infections, and organ toxicity represent persistent and clinically meaningful limitations.

Recent Applications of Propylene Carbonate as a Solvent in Sustainable Organic Synthesis
This review evaluates propylene carbonate (PC) as a non‐toxic green solvent in organic synthesis, highlighting its performance in key reactions including cross‐couplings, asymmetric hydrogenations, peptide synthesis and biocatalysis. Across these processes, PC delivers yields comparable to conventional and alternative green solvents.

Heavy metal pollution reduces soil health and threatens food safety by entering plants; however, the use of nanoparticles, biofertilizers, and organic fertilizers such as biochar offers a promising strategy for improvement and sustainable agriculture. ABSTRACT Heavy metal (HM) pollution, resulting from human activities such as mining and the excessive ...

X-Rays and Nitrogen Mustard Independent Action in Chinese Hamster Cells [PDF]
We have studied the combined effects of X-irradiation and nitrogen mustard treatment on the colony-forming ability of Chinese hamster cells. In contrast to X-irradiation, nitrogen mustard acting by itself yields an exponential dose-effect relationship ...

Crop sequencing effects of seven crops on grain yield, volunteers, and weeds in Saskatchewan
Abstract Every growing season, producers must decide which crops to grow and in what sequence to enhance returns and sustain productivity. However, when producers consider growing specialty crops like canary seed (Phalaris canariensis L.), coriander (Coriandrum sativum L.), hemp (Cannabis sativa L.), or quinoa (Chenopodium quinoa Willd.), data are ...

Abstract Compared with conventional tillage, no‐till reduces soil erosion and is considered a more sustainable practice in dryland cropping systems of the Pacific Northwest. However, weed management in these systems relies solely on herbicides, and the number of herbicide‐resistant weeds is increasing each year.

A note on the availability of organic nitrogen compounds in pot experiments
In the course of an investigation on the nitrification process in soils a series of pot experiments was set up to compare the manurial actions of some typical organic nitrogen compounds.
