Laboratory Determination Of Coal Dust Cleaning Efficacy Of A Fibrous Filter For Flooded-Bed Dust Scrubber, Neeraj Gupta, Ashish Ranjan Kumar, Steven Schafrik Mar 2021

Laboratory Determination Of Coal Dust Cleaning Efficacy Of A Fibrous Filter For Flooded-Bed Dust Scrubber, Neeraj Gupta, Ashish Ranjan Kumar, Steven Schafrik

Mining Engineering Faculty Publications

Fibrous-type dust filters are used in flooded-bed dust scrubbers to capture dust from underground room and pillar mining atmospheres. They have 10–30 layers of finely woven strands that trap particles through the interception and impaction process. A full-cone water spray is installed upstream of the filter, which floods the screen. A scrubber’s efficacy is usually measured and reported in terms of reduction in gravimetric dust concentration at a known location in a mine. This paper reports the particle-size-dependent dust removal efficiency of a fibrous filter obtained from an instrumented test-set up. A variable frequency drive and an inline flow control …

Center for Applied Energy Research Faculty and Staff Publications

This study evaluates the on use of crushed rocks (remineralizers) to increase soil fertility levels and which contributed to increase agricultural productivity, recovery of degraded areas, decontamination of water, and carbon sequestration. The use of these geological materials is part of the assumptions of rock technology and, indirectly, facilitates the achievement of sustainable development goals related to soil management, climate change, and the preservation of water resources. Research over the past 50 years on silicate rocks focused on soil fertility management and agricultural productivity. More recently, the combined use with microorganisms and organic correctives have shown positive results to mitigate …


On The Impact Of Gravity Compensation On Reinforcement Learning In Goal-Reaching Tasks For Robotic Manipulators, Jonathan Fugal, Hasan A. Poonawala, Jihye Bae Mar 2021

On The Impact Of Gravity Compensation On Reinforcement Learning In Goal-Reaching Tasks For Robotic Manipulators, Jonathan Fugal, Hasan A. Poonawala, Jihye Bae

Electrical and Computer Engineering Faculty Publications

Advances in machine learning technologies in recent years have facilitated developments in autonomous robotic systems. Designing these autonomous systems typically requires manually specified models of the robotic system and world when using classical control-based strategies, or time consuming and computationally expensive data-driven training when using learning-based strategies. Combination of classical control and learning-based strategies may mitigate both requirements. However, the performance of the combined control system is not obvious given that there are two separate controllers. This paper focuses on one such combination, which uses gravity-compensation together with reinforcement learning (RL). We present a study of the effects of gravity …


Challenges In Medicine: The Odyssey Of A Patient With Isolated Igg4-Related Eosinophilic Angiocentric Fibrosis Presenting As A Locally Destructive Sinonasal Mass, Snigdha Nutalapati, Richard O'Neal, William O'Connor, Brett T. Comer, Gerhard C. Hildebrandt Mar 2021

Challenges In Medicine: The Odyssey Of A Patient With Isolated Igg4-Related Eosinophilic Angiocentric Fibrosis Presenting As A Locally Destructive Sinonasal Mass, Snigdha Nutalapati, Richard O'Neal, William O'Connor, Brett T. Comer, Gerhard C. Hildebrandt

Otolaryngology--Head & Neck Surgery Faculty Publications

Eosinophilic angiocentric fibrosis (EAF) is an exceeding rare clinical entity and is considered a part of the spectrum of IgG4-related disease (IgG4RD). We hereby present such an unusual case of a 60-year-old female who presented to us with recurrent sinonasal mass, after a decade long haul of multiple clinical evaluations, biopsies, and debulking surgery without a definitive diagnosis. Over this period, the mass eroded through the ethmoid cells along with nasal septal destruction leading to saddle nose deformity, extended superiorly through the cribriform plates to right frontal lobe, and compressed the optic nerve leading to visual loss. Although initial biopsy …


Chronic Voluntary Alcohol Drinking Causes Anxiety-Like Behavior, Thiamine Deficiency, And Brain Damage Of Female Crossed High Alcohol Preferring Mice, Hong Xu, Hui Li, Dexiang Liu, Wen Wen, Mei Xu, Jacqueline A. Frank, Jing Chen, Haining Zhu, Nicholas J. Grahame, Jia Luo Mar 2021

Chronic Voluntary Alcohol Drinking Causes Anxiety-Like Behavior, Thiamine Deficiency, And Brain Damage Of Female Crossed High Alcohol Preferring Mice, Hong Xu, Hui Li, Dexiang Liu, Wen Wen, Mei Xu, Jacqueline A. Frank, Jing Chen, Haining Zhu, Nicholas J. Grahame, Jia Luo

Molecular and Cellular Biochemistry Faculty Publications

The central nervous system is vulnerable to chronic alcohol abuse, and alcohol dependence is a chronically relapsing disorder which causes a variety of physical and mental disorders. Appropriate animal models are important for investigating the underlying cellular and molecular mechanisms. The crossed High Alcohol Preferring mice prefer alcohol to water when given free access. In the present study, we used female cHAP mice as a model of chronic voluntary drinking to evaluate the effects of alcohol on neurobehavioral and neuropathological changes. The female cHAP mice had free-choice access to 10% ethanol and water, while control mice had access to water …

Generalized Fiducial Inference On The Mean Of Zero-Inflated Poisson And Poisson Hurdle Models, Yixuan Zou, Jan Hannig, Derek S. Young Mar 2021

Generalized Fiducial Inference On The Mean Of Zero-Inflated Poisson And Poisson Hurdle Models, Yixuan Zou, Jan Hannig, Derek S. Young

Statistics Faculty Publications

Zero-inflated and hurdle models are widely applied to count data possessing excess zeros, where they can simultaneously model the process from how the zeros were generated and potentially help mitigate the effects of overdispersion relative to the assumed count distribution. Which model to use depends on how the zeros are generated: zero-inflated models add an additional probability mass on zero, while hurdle models are two-part models comprised of a degenerate distribution for the zeros and a zero-truncated distribution. Developing confidence intervals for such models is challenging since no closed-form function is available to calculate the mean. In this study, generalized …

Fruits and vegetables are high in nutrients that are essential for a healthy lifestyle. However, they also harbor an extensive array of microorganisms such as bacteria, which can be beneficial, neutral, or pathogenic. Foodborne pathogens can contaminate produce at any stage from the farm to the consumer’s table. Appropriate washing techniques using sanitizers can reduce the risk of pathogen contamination. Issues related to maintaining concentration, efficacy, and other problems have been a challenge for the food industry and, when left unresolved, have led to different outbreaks of foodborne illnesses. In this study, the efficacy of a lytic bacteriophage cocktail was …
