Quantum seaweed algebras and quantization of affine Cremmer-Gervais r-matrices [PDF]

arXiv, 2006
We propose a method of quantization of certain Lie bialgebra structures on the polynomial Lie algebras related to quasi-trigonometric solutions of the classical Yang--Baxter equation. The method is based on an affine realization of certain seaweed algebras and their quantum analogues.

Macroalgae detritus decomposition and cross‐shelf carbon export from shallow and deep reefs

Limnology and Oceanography, EarlyView.
Abstract Macroalgal forests have been suggested to export substantial amounts of carbon to deep ocean sinks and could account for 27–34% of annual blue carbon sequestered in Australia. However, a major knowledge gap concerns how carbon in the detrital tissue of the dominant seaweed species is remineralized as it is exported offshore.

Opportunities and limitations for the introduction of circular economy principles in EU aquaculture based on the regulatory framework

Journal of Industrial Ecology, Volume 26, Issue 6, Page 2033-2044, December 2022., 2022
Abstract EU aquaculture produces only a small fraction of the internal demand of aquatic foods, but boosting this activity must be done in compliance with high standards of environmental protection and social benefits, as fostered by the policies on circular economy recently launched by the EU.

The unbroken spectrum of type-A Frobenius seaweeds [PDF]

arXiv, 2016
If $\mathfrak{g}$ is a Frobenius Lie algebra, then for certain $F\in \mathfrak{g}^*$ the natural map $\mathfrak{g}\longrightarrow \mathfrak{g}^* $ given by $x \longmapsto F[x,-]$ is an isomorphism. The inverse image of $F$ under this isomorphism is called a principal element. We show that if $\mathfrak{g}$ is a Frobenius seaweed subalgebra of $A_{n-1}=\

Moderate ocean alkalinity enhancement likely to have minimal effects on a habitat‐forming kelp across multiple life stages

Limnology and Oceanography, EarlyView.
Abstract Ocean alkalinity enhancement (OAE) is a widely considered marine CO2 removal method. Ocean alkalinity enhancement works by converting seawater CO2 into HCO3−$$ {\mathrm{HCO}}_3^{-} $$ and CO32−$$ {\mathrm{CO}}_3^{2-} $$ by electrochemical methods or the addition of alkaline minerals.

Life cycle assessment of Indonesian canned crab (Portunus pelagicus)

Journal of Industrial Ecology, Volume 26, Issue 6, Page 1947-1960, December 2022., 2022
Abstract Indonesia is an archipelagic country with abundant marine wealth that makes it the world's second largest producer of fish after China. While most of Indonesia's capture marine fisheries (80%) are consumed domestically, around 90% of blue swimming crab (BSC) products are exported, mainly in cans.

Structure, Conduct and Performance of Value Chain in Seaweed farming in India [PDF]

Among the three types of technologies available in the fisheries sector in India, seaweed farming, initially promoted as a livelihood option, has emerged as the one area which probably has the maximum potential for up-scaling. This paper has examined the

The fisheries of Zanzibar: potential for new investments [PDF]

, 2005
Zanzibar, one of the poorest areas of sub-Saharan Africa, has a good potential for foreign investment in offshore (EEZ) marine capture fisheries, in aquaculture and in fi sheries infrastructure.

On compositions associated to seasweed subalgebras of sl(n) [PDF]

arXiv, 2018
A standard seaweed subalgebra of $A_{n-1}=\mathfrak{sl}(n)$ may be parametrized by a pair of compositions of the positive integer $n$. For all $n$ and certain $k(n)$, we provide closed-form formulas and the generating functions for $C(n,k)$ -- the number of parametrizing pairs which yield a seaweed subalgebra of $\mathfrak{sl}(n)$ of index $k$.

Effects of incremental increases in grass silage proportions from different harvest years on methane emissions, urinary nitrogen losses, and protein and energy utilisation in dairy cows

Journal of Animal Physiology and Animal Nutrition, Volume 107, Issue 1, Page 37-52, January 2023., 2023
Abstract Dairy cows, methane and global warming have become publicly related terms. However, appropriate dairy cow management may in fact be part of the climate solution when viewed as part of the biogenic carbon cycle. Accordingly, governments and consumers are encouraging more sustainable, locally produced, climate friendly dairy production that ...
