A trace amount of carbon was determined by atmospheric-pressure helium microwave induced plasma atomic emission spectrometry (He-MIP-AES) with gas-phase sample introduction technique. This method was applied for the generation of a continuous flow of carbon dioxide by the acidification of carbonate ion and hydrogen carbonate ion for the determination of carbon. The generated carbon dioxide was ...
The relationship between temperature, high pH, desiccation, decomposition, pathogen destruction, and user operation in active double vault urine diverting (DVUD) composting latrines located in the Bocas del Toro region of Panama was assessed. Latrine samples were analyzed for temperature, pH, % moisture, carbon-to-nitrogen (C/N) ratio, and presence of specific pathogens. Surveys and visual insp...
The earliest studies in the late 19th century on Streptococcus pneumoniae (S. pneumoniae) carriage used saliva as the primary specimen. However, interest in saliva declined after the sensitive mouse inoculation method was replaced by conventional culture, which made isolation of pneumococci from the highly polymicrobial oral cavity virtually impossible. Here, we tested the feasibility of using ...
Low-cost drying technologies suitable for rural farming areas are presented. Some of the important considerations with regard to their suitability include: 1. Low initial capital; 2. easy-to-operate with no complicated electronic/ mechanical protocol, and 3. effective in promoting better drying kinetics. The drying technologies that were selected include fluidized bed, spouted bed, infrared, so...
As the freshwater crisis looms, metal-organic frameworks (MOFs) with stepped isotherms lie at forefront of desiccant development for atmospheric water harvesting (AWH). Despite numerous studies on sorption kinetics in MOF desiccants, AWH sorbents are a challenge to quantify. Here, we report that seven known MOFs and industry-standard Syloid limited by diffusion sorbent bed surface. A quantitati...
In this paper, an in-wheel vibration absorber for In-wheel-motor electric vehicle (IWM EV) is designed, and a comprehensive control strategy of in-wheel absorber and vehicle suspension is proposed to improve vehicle ride comfort. The proposed in-wheel vibration absorber, designed for suppressing the motor vibration, is composed of a spring and a controllable damper. The values of in-wheel sprin...
Annals of Chemical Science Research Recent Advances in Atmospheric Water Harvesting by Desiccant Materials Mahmoud Parvazinia* Iran Polymer and Petrochemical Institute, *Corresponding author:Mahmoud Parvazinia, Tehran, Submission: January 02, 2023;Published: 20, 2023 DOI: 10.31031/ACSR.2023.03.000564 Volume3 Issue3January,
In this paper, a new cascaded wheel-slip control strategy based on wheel slip and wheel acceleration measurements is presented. This new algorithm is able to stabilize globally and asymptotically the wheel slip around any prescribed setpoint, both in the stable and unstable regions of the tyre.
Rodents anticipate rewarding stimuli such as daily meals, mates, and stimulant drugs. When a single meal is provided daily at a fixed time of day, an increase in activity, known as food anticipatory activity (FAA), occurs several hours before feeding time. The factors affecting the expression of FAA have not been well-studied. Understanding these factors may provide clues to the undiscovered an...
Back and Forward Moving Scheme of Front Wheel Raising for Inverse Pendulum Control Wheel Chair Robot
A power assist wheel chair robot by which a patient can climb over steps/curbs without any helper's assistance is proposed. A patient can maintain inverse pendulum control of the wheel chair after raising its front wheels. Next, a patient can move to the step maintaining the inverse pendulum control, and can climb over the step being assisted by DC motor force. A light weight wheel chair system...
