A secular increase in continental crust nitrogen during the Precambrian [PDF]

Geochem. Persp. Let. (2017) 4, 24-28, 2017
Recent work indicates the presence of substantial geologic nitrogen reservoirs in the mantle and continental crust. Importantly, this geologic nitrogen has exchanged between the atmosphere and the solid Earth over time. Changes in atmospheric nitrogen (i.e. atmospheric mass) have direct effects on climate and biological productivity. It is difficult to

Corn cob pyrolysis: A systematic literature review of methods and applications

The Canadian Journal of Chemical Engineering, EarlyView.
Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.

Biofortification of oil quality, yield, and nutrient uptake in Indian mustard (Brassica juncea L.) by foliar application of boron and nitrogen

Frontiers in Plant Science, 2022
Indian mustard (Brassica juncea L.) is an essential oilseed crop that offers important nutrients to human beings. However, the concurrent micronutrient deficiencies including boron (B), sulfur (S), and nitrogen (N) could pose a significant threat to ...

Rethinking Chlorine: Essential Chemical or Replaceable Risk?

ChemSusChem, Accepted Article.
This review critically examines the dual nature of chlorine as both an indispensable base chemical and a potential risk. Chlorine and its by‐product hydrogen chloride play essential roles in the production of pharmaceuticals, plastics, agrochemicals, and disinfectants.

Impact of Indian Mustard (Brassica juncea) and Flax (Linum usitatissimum) Seed Meal Applications on Soil Carbon, Nitrogen, and Microbial Dynamics

Applied and Environmental Soil Science, 2012
There is a critical need to investigate how land application of dedicated biofuel oilseed meals affects soil ecosystems. In this study, mustard (Brassica juncea) and flax (Linum usitatissimum) seed meals and sorghum-sudangrass (Sorghum bicolor) were ...

Mercaptans in malodorants break disulfide bridges in human serum albumin and form adducts suitable as biomarkers of exposure in vitro

Drug Testing and Analysis, EarlyView.
Disulfide adducts of mercaptans with cysteine residues in human serum albumin were detected as tripeptides and dipeptides after proteolysis with proteinase K. All peptide adducts were detected simultaneously with a mass spectrometry‐based method working in the scheduled multiple reaction monitoring (sMRM) mode.

Connecting spatial and frequency domains for the quaternion Fourier transform [PDF]

arXiv, 2015
The quaternion Fourier transform (qFT) is an important tool in multi-dimensional data analysis, in particular for the study of color images. An important problem when applying the qFT is the mismatch between the spatial and frequency domains: the convolution of two quaternion signals does not map to the pointwise product of their qFT images.
