Investigation of CO2 Sequestration for the Assessment of the Impact on Resource Storage with Co-production of Brine

In order to reduce Green House Gases, Carbon-dioxide (CO2) storage in deep saline aquifers is a viable commercial application for minimizing emissions. It is important to understand surface area needed to predict large scale CO2 storage while fully utilizing injection capacity. This study presents results from varying Injection pressure and well spacing to find minimal-effective well spacing required to store CO2. The study shows pressure management to manipulate hydrodynamic behavior of CO 2 in saline formations system. In conjunction, understanding the interplay of CO2 dissolution, buoyancy flow, and capillary forces in regulating the behavior of the injected CO2 plume are important. Pressure manipulated by changing injection pressure with selected brine co-production, a technique known as CO2 sequestration.;A 3-D reservoir model has been utilized to model CO2 sequestration behavior in a compositional simulator, CMG Builder. Mount Simon Sandstone (Cambrian) was selected as a \u27base case model\u27 for its recognition as an important deep saline reservoir with potential to serve as a largescale commercial CO2 storage field in the Midwestern United States.;The study shows the impact of selected injection pressure on the utilization of brine aquifer. It is recommended to store CO2 with 4000 -- 4500 psi injection pressure range for optimum storage and production conditions

Electrochemical Corrosion Properties of Ternary Al and Quaternary Zr Added Bell Metal in 0.1M NaCl Solution

The electrochemical corrosion property of ternary Al and quaternary Zr added Bell metal in 0.1M Sodium Chloride solution has been experimentally conducted at room temperature. Electrochemical impedance spectroscopy (EIS) method and Potentiodynamic polarization technique are used to carry out the electrochemical investigation. Microhardness test is also conducted for all three alloys and it reveals that Al addition increases the hardness of bell metal due to the formation of different intermetallic precipitates of Cu and Al. Optical Micrograph as well as Scanning Electron Micrograph have also been studied to characterize their surface condition. It is found that Zr addition refines the grain structure of the alloy and results in increase of hardness. The EIS study reveals that the corrosion resistance is seem to be augmented with the addition of ternary Al and quaternary Zr to bell metal. The potentiodynamic polarization curves disclose that both ternary Al added and quaternary Zr added alloy show better corrosion performance than the base bell metal alloy due to the formation of stable aluminium oxide film. The currentdensity (Icorr) of base bell metal showed higher value than both ternary Al added and quaternary Zr added bell metal alloys. The corrosion potential (Ecorr) and the open circuit potential (OCP) were seen to be moved to the more positive direction for the Al and Zr added alloys. Microstructure and SEM study of the alloys after corrosion revealed a formation of an oxide film on the surface of the ternary A and quaternary Zr added alloys, the probable cause of which is the presence of Al in the respective alloys

Optimization of Polyacrylic Acid Coating on Graphene Oxide-Functionalized Reverse-Osmosis Membrane Using UV Radiation through Response Surface Methodology

Reverse osmosis (RO) is affected by multiple types of fouling such as biofouling, scaling, and organic fouling. Therefore, a multi-functional membrane capable of reducing more than one type of fouling is a need of the hour. The polyacrylic acid and graphene oxide (PAA-GO) nanocomposite functionalization of the RO membrane has shown its effectiveness against both mineral scaling and biofouling. In this research, the polyacrylic acid concentration and irradiation times were optimized for the PAA-GO-coated RO membrane using the response surface methodology (RSM) approach. The effect of these parameters on pure water permeability and salt rejection was investigated. The models were developed through the design of the experiment (DoE), which were further validated through the analysis of variance (ANOVA). The optimum conditions were found to be: 11.41 mg·L−1 (acrylic acid concentration) and 28.08 min (UV activation times) with the predicted results of 2.12 LMH·bar−1 and 98.5% NaCl rejection. The optimized membrane was prepared as per the model conditions, which showed an increase in both pure water permeability and salt rejection as compared to the control. The improvement in membrane surface smoothness and hydrophilicity for the optimized membrane also helped to inhibit mineral scaling by 98%.This publication was made possible by NPRP13S-0207-200289 from the Qatar National Research Fund (a member of the Qatar Foundation).

Carum carvi Modulates Acetaminophen-Induced Hepatotoxicity: Effects on TNF-α, NF-κB, and Caspases

Carum carvi is a well-known herb traditionally used as a spice in Asian countries. Acetaminophen is a known marketed drug mainly used as an analgesic. It has been scientifically proven that consumption of acetaminophen (paracetamol) is associated with liver toxicity if taken in high doses without medical supervision. The present study evaluated the in vivo antioxidant and hepatoprotective efficacy of Carum carvi against acetaminophen-induced hepatotoxicity in Wistar rats. Our results demonstrate that Carum carvi, at doses (mg/kg) of 100 (D1) and 200 (D2), showed inhibitory properties for DNA-sugar damage, lipid peroxidation, DPPH scavenging, and increased reducing potential in a concentration-dependent manner. Our results also confirm that liver toxicity associated with paracetamol, such as depletion of reduced glutathione and antioxidant enzyme levels, as well as induction of cytochrome P450, oxidative stress, apoptosis, and inflammatory cytokines, was efficiently restored by Carum carvi treatment in rats. Moreover, the expression of redox-sensitive transcription factors, namely, NF-κB and TNF-α levels, was also modulated by Carum carvi in the rats. In summary, our study confirms that Carum carvi inhibits inflammation and oxidative stress, thereby protecting liver cells from paracetamol prompted hepatotoxicity

Access to mass media and awareness of sexually transmitted diseases (STDs) among the truck drivers in Dhaka City : do mass media make them aware?

The major objective of the study is to determine the association between access to mass media such as television, newspaper, radio and internet and level of STDs awareness among the truck drivers in Dhaka city. This research utilized purposive sampling technique to select 250 respondents from the study areas. The results of the study demonstrate that a significant number of respondents (88%) had heard of STDs. However, most of them (70%) did not have the awareness of STDs. It again reveals that radio, newspaper and internet did not play significant role in making them aware of STDs. Bivariate results of the study indicate that respondents with higher degree of exposure to television were more likely to be aware of STD like HIV. This study concludes that mass media may play vibrant role in disseminating information about not only HIV but also other STDs such as Chlamydia, Herpes, Hepatitis B and Human Papilloma Virus (HPV)

Wearable Alcohol Monitoring Device for the Data-Driven Transcutaneous Alcohol Diffusion Model

Wearable alcohol monitoring devices demand noninvasive, real-time measurement of blood alcohol content (BAC) reliably and continuously. A few commercial devices are available to determine BAC noninvasively by detecting transcutaneous diffused alcohol. However, they suffer from a lack of accuracy and reliability in the determination of BAC in real time due to the complex scenario of the human skin for transcutaneous alcohol diffusion and numerous factors (e.g., skin thickness, kinetics of alcohol, body weight, age, sex, metabolism rate, etc.). In this work, a transcutaneous alcohol diffusion model has been developed from real-time captured data from human wrists to better understand the kinetics of diffused alcohol from blood to different skin epidermis layers. Such a model will be a footprint to determine a base computational model in larger studies. Eight anonymous volunteers participated in this pilot study. A laboratory-built wearable blood alcohol content (BAC) monitoring device collected all the data to develop this diffusion model. The proton exchange membrane fuel cell (PEMFC) sensor was fabricated and integrated with an nRF51822 microcontroller, LMP91000 miniaturized potentiostat, 2.4 GHz transceiver supporting Bluetooth low energy (BLE), and all the necessary electronic components to build this wearable BAC monitoring device. The %BAC data in real time were collected using this device from these volunteers’ wrists and stored in the end device (e.g., smartphone). From the captured data, we demonstrate how the volatile alcohol concentration on the skin varies over time by comparing the alcohol concentration in the initial stage (= 10 min) and later time (= 100 min). We also compare the experimental results with the outputs of three different input profiles: piecewise linear, exponential linear, and Hoerl, to optimize the developed diffusion model. Our results demonstrate that the exponential linear function best fits the experimental data compared to the piecewise linear and Hoerl functions. Moreover, we have studied the impact of skin epidermis thickness within ±20% and demonstrate that a 20% decrease in this thickness results in faster dynamics compared to thicker skin. The model clearly shows how the diffusion front changes within a skin epidermis layer with time. We further verified that 60 min was roughly the time to reach the maximum concentration, Cmax, in the stratum corneum from the transient analysis. Lastly, we found that a more significant time difference between BACmax and Cmax was due to greater alcohol consumption for a fixed absorption time
