The research trends of metal-organic frameworks in environmental science: a review based on bibliometric analysis
No full textMetal-organic frameworks, an emerging class of porous material, have developed rapidly in recent years. In order to clarify the application of metal-organic frameworks in the field of environmental science, 1386 articles over the last 20 years were obtained from Scopus and analysed by the bibliometric method. And the collaboration between countries, institutions and authors and the co-occurrence of keywords were also conducted using VOS viewer. The results indicated that this area of research has entered a fast-developing stage. The number of articles published has grown from 7 articles in 1999 to 378 articles in 2018. The most productive country was China with 626 articles published. The most productive institution was the Chinese Academy of Sciences, and the most productive author was Jhung SH from Kyungpook National University of South Korea. Although metal-organic frameworks have been widely used in adsorption and catalytic degradation of pollutants from the environment, the removal mechanism of pollutants by MOFs, the stability improvement and the cost reduction of metal-organic frameworks are still the main challenges for their practical applications
Author Identification from Song Lyrics
No full textMachine Learning (ML) tools have been used extensively in a wide variety of domains
recently. Due the enormous amount of data being produced, machine learning techniques
are being heavily used to make sense of data & derive meaningful results. Using machine
learning tools, we can turn the data into knowledge.
Music is one of the truest forms of art. Bangladesh has a great history of music with a
great tradition of song writing over centuries. Authorship attribution is the way of
identifying the author from a linguistic corpus.
This paper demonstrates a guideline to identify the author of a Bengali song from the
lyrics of that song using machine learning. This research work presents the first work on
machine learning approach for author attribution from the lyrics of a song. Here six
methods of machine learning are used for the author identification and high accuracies
have been achieved from these methods. It is observed that Naïve Bayes method provides
higher accuracy in comparison with the other methods

Pilot-scale treatment of pharmaceutical berberine wastewater by Fenton oxidation
No full textFenton oxidation was used to treat the berberine finished mother liquor wastewater in pilot scale. To evaluate berberine and COD removal efficiency, the main factors, including pH, H2O2 dosage, Fe2+/H2O2 mass ratio and the water flow (Q), were optimized using response surface methodology (RSM). The results showed that under the optimal conditions, pH 3, H2O2/COD molar ratio of 1.25, Fe2+/H2O2 molar ratio of 0.1, Q 100 L/h [with hydraulic retention time (HRT) of 2.5 h], the COD and berberine removal efficiencies were 35.6 and 91.4 % at initial COD concentration of 4061 mg/L and berberine concentration of 709 mg/L, respectively. The (BOD5)/(COD) ratio (B/C) of the wastewater increased from 0 to 0.3, indicating significantly improved biodegradability of wastewater
Efficiency comparison for treatment of amantadine pharmaceutical wastewater by Fenton, ultrasonic, and Fenton/ultrasonic processes
No full textAmantadine wastewater is quite recalcitrant to biological treatment because of the quite stable adamantine backbone. To improve amantadine wastewater biodegradability, the combined advanced oxidation process, such as Fenton/ultrasonic process, was proposed to treat amantadine industrial wastewater. The efficiency comparisons for the treatment of amantadine wastewater using Fenton oxidation, ultrasonic process, and Fenton/ultrasonic process were conducted. The results of wastewater treatment with Fenton/ultrasonic process indicated that the TOC removal reached 65.6 %, showing almost 4 times of the degradation rate by individual oxidizing action of hydrogen peroxide. Kinetic study revealed that degradation of amantadine wastewater fitted first order kinetics for the three processes under investigation. The synergistic index (f) for the combined process was calculated as 2.24, indicating an obvious synergy effect. The energy consumption for hydrodynamic cavitation-based process has been analyzed on the basis of cavitational yield. Fenton and combined processes reduced the toxicity of wastewater by 50 and 55 %, respectively, while ultrasonic process showed no obvious effect on toxicity reduction. The monitoring of treated wastewater by EEM and GC–MS showed that the Fenton/ultrasonic process effectively removed the organic matters in the wastewater, especially the biodegradation-resistant matters containing benzene ring
The Singer or the Song? Developments in Performers' Rights from the Perspective of a Cultural Economist
No full textOver the last century, performers gradually acquired statutory protection of their economic and moral
rights. These rights are not copyright in the legal sense but neighboring rights and until recently, they
were mainly remuneration rights that are collectively administered. With the WPPT (WIPO
Performers and Phonograms Treaty), performers now have individual exclusive rights for digital
performances; this leads to the question: what has motivated this change – is it a change in the
perception of the value of performer or a change brought about by the changing technology of copying or,
indeed, a change that reflects different economic costs and benefits? The paper discusses the role of
copyright law as an incentive to performers and asks if the economic role of the performer is so different
from that of the author. The conclusion is that a complex interaction of the legal regulations, economic
conditions and institutional arrangements for administering these new rights will determine the outcome
Adsorption of berberine by polymeric resin H103: kinetics and thermodynamics
No full textResin adsorption is a promising technology for pharmaceutical removal from wastewater. In this study, polymeric adsorption resin H103 was studied for the removal of berberine from pharmaceutical wastewater. The effects of adsorption temperature, initial pH and equilibrium time on adsorption were investigated. It was found that the optimal temperature, pH and equilibrium time were 343 K, 7.0, and 8 h, respectively, for berberine removal by H103 adsorption. The adsorption kinetics of berberine by H103 could be simulated by first-order kinetic model. The results show that adsorption rate was dependent on both film diffusion and intra-particle diffusion, which limited the adsorption rate when the H103 dosage was less than 2.0 g. When H103 dosage was more than 2.0 g, the film diffusion became the only control factor of adsorption rate. The adsorption isotherms could be expressed by Freundlich model very well indicating that the adsorption of berberine by H103 was a spontaneous and endothermic process
Introduction to the Sustain H2O project
No full textIn the framework of the EU-China Environmental Sustainability Program, the SUSTAIN H2O project was launched in 2013 and ran over 36 months until 2016. Sustain H2O is an abbreviation which stands for “Demonstration of Pollution Discharge Management for Water Quality Improvement in the Songhuajiang-Liaohe River Basin (SLRB)”. The SLRB represents China’s old industrial base with a large number of water-polluting industries. It has been selected as it is a key river basin for water pollution control and water environment management with clearly defined challenges in terms of pollution emission reduction and water quality improvement. Some of these challenges/problems include excessive discharge of pollutants, no optimal load allocation mechanism of quantity control, poor water quality and severely damaged water ecology as well as high risk of environmental pollution accidental events that threaten the safety of drinking water sources. Moreover, the SLRB is a trans-national (transboundary) river catchment, flowing from China to Russia, and therefore is well suited as a joint Sino-EU action
River health assessment, ecological restoration and management system
No full textHealthy river ecosystems maintain an integrity of their structural composition (including physical, chemical and biological composition), ecological processes and ecosystem functions. They have the ability to resist disturbance and restore their structure and function, and also provide ecological services in accordance with natural and human needs. River health assessment can identify water bodies with poor health and their belonging watersheds, and provide possible causes affecting river ecological conditions. In Europe and the United States and other developed countries, river health assessment has turned out to be an effective method for environmental water management
