ocean law in times of health emergency deep seabed mining contributions and its fear of overExploitation
Social Science Research Network, 2021Co-Authors: Laisa Branco De AlmeidaAbstract:Abstract: The deep seabed has one of the most enriched biodiverse places on Earth. Among seabed minerals, scientists have found some essential biomedical breakthroughs derived from hydrothermal vents, which are involved in treating disease outbreaks. Futuristic as it may sound, new pharmaceutical discoveries pressure the International Seabed Authority (ISA) into strengthening its global rules on mining Exploitation beyond areas of national jurisdiction (ABNJ), assessing the effects on the marine environment in the deep-sea floor beyond the continental shelf. This paper presents a general evaluation of the existing legal system of deep seabed mining. It highlights that, increasingly, pharmaceutical companies are shifting to ABNJ seabed areas for Exploitation, pressuring the international order for a more coherent and effective mining Exploitation system for the next decade. The analysis of international legal frameworks for the Law of the Sea is notable. However, there are still substantial gaps in deep seabed mining’s global governance, expected to commence soon, as ISA rushes to approve a new international mining code. The result supports a transparent mining Exploitation Process in ABNJ, facilitating cooperation between sectors and between countries, fostering equitable sharing, and preserving the fragile ecosystem.

eucalyptus globulus biomass residues from pulping industry as a source of high value triterpenic compounds
Industrial Crops and Products, 2010Co-Authors: Rui M A Domingues, G D A Sousa, Carmen S R Freire, Armando J D Silvestre, Pascoal C NetoAbstract:Abstract The chemical composition of the lipophilic extracts of Eucalyptus globulus harvesting residues and bark generated by the pulp industry was studied by gas chromatography–mass spectrometry. Triterpenoids, mainly triterpenic acids with lupane, ursane and oleanane skeletons (namely, betulonic, betulinic, ursolic, oleanolic, 3-acetylursolic and 3-acetyloleanolic acids) were the major components detected. Triterpenoids contents range from 1.2 g/kg to 121.1 g/kg in fruits and surface layers of branches bark residues, respectively, being the triterpenic acids highly concentrated in surface layers of E. globulus biomass. The results demonstrate that these biomass residues can be considered as promising sources of valuable bioactive chemicals, opening new strategies to up-grade the pulp industry residues, within an integrated biorefinery context. The Exploitation viability of the bark from an industrial pulp mill debarking Process was evaluated. The recovery of triterpenoids from bark samples collected along the industrial debarking line decreases substantially, showing that a successful Exploitation Process of these valuable compounds in an integrated way will require the development of modifications on the debarking systems.

an exergy based energy efficiency analysis on gas production from gas hydrates reservoir by brine stimulation combined depressurization method
Energy, 2021Co-Authors: Xiaohui Wang, Yun Chen, Jingyu Kan, Changyu Sun, Guangjin ChenAbstract:Abstract Before performing commercial scale production of natural gas hydrates (NGHs), it is inevitable to estimate the productivity, production period, optimal operation parameters, and further evaluate the technical and economic feasibilities of NGHs field production. The dissociation of gas hydrates is an endothermic Process. This needs to compensate additional energy, such as chemical energy, geothermal energy and electricity, etc., in order to keep high dissociation rate. Exergy is a basic parameter that used for various energy systems as a potential tool for design, analysis and optimization. This work provided an exergy analysis method to evaluate the economic efficiency of NGHs Exploitation Process by brine stimulation combined depressurization method. The input data including cumulative volume of gas production, mass of water production and gas-to-water ratio was obtained by the numerical simulation of TOUGH + HYDRATE. Through the exergy analysis, the total productivity and production period could be determined. These have rarely been reported. The influences of operation parameters, such as well spacing, injection temperature and injection rate of brine on net exergy production were investigated for guiding the set of optimal operating conditions. Since the cost may be one of the biggest challenges for NGHs production, this work suggests making full use of all kinds low-level energy sources to improve energy efficiency, such as brine with high concentration produced by desalination, tidal energy, wind energy, etc.
