Dietary phosphorus requirement of pejerrey fingerlings (Odontesthes bonariensis)

Revista Brasileira de Zootecnia, 2014
To determine the available phosphorus requirement of pejerrey fish, four semi-purified diets were formulated to contain increasing available phosphorus levels (0.90, 2.7, 5.7 and 8.3 g/kg).

Equilibrium of Blockchain Miners with Dynamic Asset Allocation [PDF]

arXiv, 2020
We model and analyze blockchain miners who seek to maximize the compound return of their mining businesses. The analysis of the optimal strategies finds a new equilibrium point among the miners and the mining pools, which predicts the market share of each miner or mining pool.

MiNet: A Convolutional Neural Network for Identifying and Categorising Minerals [PDF]

Agangiba, M.A., Asiedu, E.B. and Aikins, D., 2020. MiNet: A Convolutional Neural Network for Identifying and Categorising Minerals. Ghana Journal of Technology, 5(1), pp.86-92, 2021
Identification of minerals in the field is a task that is wrought with many challenges. Traditional approaches are prone to errors where there is no enough experience and expertise. Several existing techniques mainly make use of features of the minerals under a microscope and tend to favour a manual feature extraction pipeline.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...
