Biomass Char Steam Gasification in Fluidized Reactor Using Nuclear Heat

Abdelhamid BELGHIT
The energy resources diversification has been increased with the energy crisis, in particular, the renewable energies and optimal management have become essential in the context of sustainable development. The conventional auto-thermal gasification processes burn part of the carbonaceous compound in order to supply the energy necessary to enhance gasification reactions. This energy could be provided as well by a nuclear reactor of IV generation. The nuclear heat is transferred from the VHTR to a...

Electrocoagulation Process in the Context of Disinfection Mechanism

Djamel Ghernaout, Noureddine Elboughdiri
During the last three decades, the electrocoagulation (EC) process has known an exemplary renaissance in the field of water and wastewater treatment. Sev-eral researchers focused on applying this electrochemical technology in re-moving diverse pollutants such as pathogens. During EC method, the coagulant is furnished via solubilizing sacrificial electrodes upon an applied electric field. The easiness of the technology and the side phenomena involving the genera

AVO Didactic Analysis from Simplified Modeling of Seismic Data in Libra Oil Field of the Pre-Salt Region, Brazil

Kaio da Silva Pimentel Figueiredo, Kaendra Williams Temoteo, Rafael Ximenes Goncalves, Yasmim Monteiro Cordeiro, Rogério Manhaes Soares, Hans Schmidt Santos, Claudiomar Rodrigues Franco, Felipe Barbosa Venancio de Freitas, Christyne Barros de Sá
In this study, a certain zone of Libra oil field of the pre-salt region was se-lected to be analyzed for didactic purposes in order to simulate AVO re-sponses. The region was modeled using seismic data, setting up a typical oil system with source rock (shale), reservoir rock (sandstone), and seal rock (salt). Thus, a set of parameters such as seismic wave velocity, density and Poisson’s ratio for the studied zone w

Assessing the Floristic Biodiversity and Carbon Stock in a Republic of Congo’s Forest Ecosystem

Donatien Nzala, Romeo Ekoungoulou, Bernadin Y. Ngoumba
Reforestation management goes through the knowledge of the tired out evolution after a forestry rest. The aim of this study was to assess biodi-versity concerning Terminalia superba Engl. & Diels and its undergrowth, and then quantify sequestered carbon stocks to appreciate the impact of reforestation on forest recovery and the enhancement of carbon stocks. The study was conducted at Bilala artificial forest in southeastern Re

Carbon Stocks in Aboveground and Belowground Biomass of Sub-Humid Tropical Forest in Southwestern Nigeria

Habeeb Ajibola Yusuf, Jesumbo Joseph Oludipe, Oluwatoyin Olajumoke Adeoye, Idowu Ezekiel Olorunfemi
This study aimed at estimation of carbon stocks in aboveground and below-ground biomass of sub-humid young forest land in south-western Nigeria. Different species of trees were analysed. Results gathered indicated that the forest studied had an average aboveground carbon stock of live trees as 0.00407 t. Terminalia superba (0.00698 t C) has the highest carbon stocks and diameter at breast height (Dbh) of 5.80 cm while Triplochiton

Identification of Petroleum Degrading Bacteria and Construction of Petroleum Degrading Agent

Xingling Tao, Yabin Zhan, Tao Jiang, Chuanjiong Hu
The aim of this study is to construct petroleum degrading agent (PDA) which can effectively degrade oil. By enrichment, domestication, and separation of culture from the soil sample of Qianjiang Guanghua Oilfield, the pure culture of three petroleum degrading bacteria G-40, G-53, and G-94 was identified from the medium supplemented with oil, which served as the sole source of carbon. The species of G-40 and G-53 were preliminarily

Research on the Microbial Community Structure of Wooden Relics and the Preservation of Water Environment: Illumina MiSeq Sequencing

Liu Tang, Jingjing Xing, Qiong Lei, Zuming Qiu, Jun Zhang, Li’an Ma
[Objective] Microorganisms are an important disease in archaeological wood lacquer. The effect of single microorganism on the erosion of wooden relics is small, but the microbial community is more harmful to the wooden relics. Therefore, it is very important to acquaint the microbial community structure of wooden relics and their preservation environment. [Methods] Illumina MiSeq sequencing method was used in this study to explore

Case Study of Baiyun and Caohai Lakes Implies How to Implement Wetland Restoration/Creation

Lin Xiao, Qun Zhang, Guifeng Wei, Sixi Zhu, Fanyang Yu, Boping Han
This work discusses how to implement wetland restoration/creation from the viewpoint that wetland aquatic plants are divided into four life forms: emergent, submergent, floating and floating leaf plants. Caohai Lake and Baiyun Lake were selected to discuss the difference of the species richness changes during the creation/restoration process. Baiyun Lake and eight surrounding wetlands have been selected to discuss how the species

Impact of Climate Change on the Global Environment and Associated Human Health

Zhiying Shi
As an important part of the natural environment on which human beings live, any change in climate will affect the natural ecosystem, social economy and human health. The impact of global climate change on human beings will be comprehensive, multi-scale and multi-layered. This paper mainly explores the research progress on the direct and indirect impacts of climate change on human health. It considers that

Bioremediation of Refinery Oil Contaminated Soil

Xingling Tao, Li-An Ma
Objective: In order to study low activity of petroleum-degrading strains. Methods: We added oil degrading strains to compost, the compost is made of soybean meal, corn flour, bran and sawdust, in the last, we added the oil degrading strains-compost contaminated soil. Result: The oil removal rates were determinated by gravimetric method. The oil removal rates of control group, oil contaminated soil compost grou
