Viability And Ecology Based Tools For Studying Antibiotic Resistance, Nicole Fahrenfeld 2019 Rutgers University

Viability And Ecology Based Tools For Studying Antibiotic Resistance, Nicole Fahrenfeld

Sustainability Seminar Series

Over 2 million people are sickened and at least 23,000 people die in the U.S. of antibiotic resistant infections each year. Community acquired infections in humans have been linked with environmental sources of antibiotic resistance. Mitigating the risk of environmental AR infections requires understanding hot spots for AR as well as the potential for horizontal gene transfer. A series of case studies will be presented towards understanding hot spots of antibiotic resistance genes in viable cells.

The Water/Energy Nexus: Climate, Consumption And Ecosystem Services, Hildegaard D. Link 2019 CUNY Graduate Center

The Water/Energy Nexus: Climate, Consumption And Ecosystem Services, Hildegaard D. Link

Dissertations, Theses, and Capstone Projects

Water and energy are drivers of living systems. This work provides an assessment of the Water Energy Nexus in the United States, comparing the well-watered north-east and the arid west. Electric grid systems are most stressed on hot summer afternoons. Grid stress can lead to cascading failures of electricity, water and wastewater treatment systems. (Zimmerman, 2017) Water for power generation and/or water supply depend on ecosystem services. The ecosystem services and resource trade-offs embedded in provision of a watt of power and an ounce of potable water, however, have yet to be comprehensively enumerated nor have the cost relationships been …


Effect Of Nmr Technology-Based Ultrasonic Frequency On Stimulated Cracking Of Coal, MA Huiteng, ZHAI Cheng, XU Jizhao, SUN Yong 2019 School of Safety Engineering, China University of Mining & Technology, Xuzhou 221116, China National; Engineering Research Center for Coal Mine Gas Control, Xuzhou 221116, China

Effect Of Nmr Technology-Based Ultrasonic Frequency On Stimulated Cracking Of Coal, Ma Huiteng, Zhai Cheng, Xu Jizhao, Sun Yong

Coal Geology & Exploration

In order to further study the effect of ultrasonic frequency on the stimulated cracking effect of coal, the paper conducted the crack experiment on the original coal samples by using the ultrasonic generation meter, and measured the coal by using the NMR equipment through analyzing the T2 curve, the changes of pore structure before and after coal sample cracking were deeply studied. The results show that the pore structure of coal can be effectively improved by the ultrasonic wave. After the crack induced by the ultrasonic wave, the pore quantity inside the coal increased and the total porosity, effective …

Advances On Geological-Geochemical Research Of Coal-Type Uranium In China, Zhou Xianqing, Qin Yong, Lu Lu

Coal Geology & Exploration

There is a huge gap in uranium resources in China. Only developing traditional uranium resources is unable to meet the increasing demand in energy and national defense construction. The exploitation and utilization of coal-type uranium resources can relieve the pressure of demand for uranium resources to a certain extent. By summarizing the research results of coal-type uranium in recent years, the ore location, uranium content range, formation time and distribution range of coal-bearing strata of major coal-type uranium deposits in China, and the definition criteria of coal-type uranium are given, which provides a basis for the classification of coal-type uranium …

Damage Mechanism And Countermeasures Of Reservoir With Abnormal Pickup Of Cbm Flow Pressure In Well, Jia Huimin, Hu Qiujia, Qi Kongjun, Qin Mengfu, Mao Chonghao, Zhang Guangbo

Coal Geology & Exploration

The reasonable control of the casing pressure and the bottom-hole pressure and the reasonable depressurization of reservoir pressure is the key technology for the CBM development. The pickup of the bottom-hole flow pressure(BHFP) will restrain CBM' desorption, lead to reservoir permeability damage and reduce the production of CBM wells. Based on production practice of Fanzhuang block in Qinshui basin, this paper puts forward the cause of a CBM abnormal well type, pickup of the BHFP, clarifies the damage mechanism of the pickup of the BHFP through theoretical research and field data analysis, and puts forward the evaluating method of the …

Analysis And Application Of Key Influencing Factors Of Cbm Well Fracturing Effects In Shizhuang Area, Qinshui Basin, Xue Haifei, Zhu Guanghui, Wang Wei, Lu Xiaoxia, Wang Minghao, Wang Yanbin

Coal Geology & Exploration

CBM fracturing effect has many influencing factors. Development effect with the same technology is different in different area. Based on a large amount of geological and engineering data in Shizhuang block, it was found that high geo-stress affects fracture extension and support in CBM fracturing, and difference between horizontal stress affects fracture direction and morphology. Coal seam with poor coal structure can produce large amount of gum during fracturing, which will block the diversion channel and result in poor fracturing effect. Engineering factors affecting fracturing effect mainly include the fracturing fluids performance, displacement, prepad fluid proportion and hole enlargement ratio. …

Influence Of Internal Friction Angle On Damage Constitutive Model Of Freeze-Thaw Rock, Yuan Chao, Zhang Huimei, Meng Xiangzhen, Yang Gengshe, Wu Luyuan

Coal Geology & Exploration

Based on Weibull random distribution and damage mechanics theory, starting from the characteristics of rock deformation process, the Drucker-Prager criterion was used to establish a damage constitutive model that can reflect the characteristics of rock various deformation stages. Through the conventional triaxial compression test of frozen-thawed sandstone, the Mohr stress circle was used to obtain the cohesion and internal friction angle of the sandstone under different freeze-thaw cycles. The model theoretical curve and the test curve of freeze-thaw sandstone were compared to verify the model rationality. By varying the internal friction angle, whether the friction angle has an effect on …
