Design and Optimization of a Double‐Column Vapor Recompression Heat Pump Distillation Process via NSGA‐II for Separating Ternary Wide‐Boiling Mixtures

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a novel double‐column vapor recompression heat pump (DCVRHP) distillation process for separating ternary wide‐boiling‐range mixtures under two different vapor conditions: n‐hexane/n‐heptane/n‐octane using low pressure steam and n‐hexanol/n‐octanol/n‐decanol using high pressure steam.

Exploring Influence of MgO/Na2O on Melting Characteristics and Viscosity–Temperature Characteristics of Coal Slags Under Entrained Flow Gasification Condition

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Characteristics of high alkali in Zhundong coal ash may cause ash‐related slag discharge problems at entrained‐flow‐bed (EFB) gasifier. In this study, through exploring melting characteristics and viscosity–temperature characteristics, it is found that MN05, MN14, and MN23 show low FTs (< 1160°C).

STUDIES ON PERFORMANCE OF AIR ENTRAINED CONCRETE INFLUENCED BY THE VARIATIONS OF CEMENT CONTENTS, THE WATER CEMENT RATIO AND THE AMOUNT OF ENTRAINED AIR

Transactions of the Japan Society of Civil Engineers, 1957
The measurements on heat of hydration and the observations of hydration process by microscopic picture have clarified the following points: the concrete with large water cement ratio (w/c) promoted the hydration up to the age 91 days, having a small increase of strength while the one with small water Cement ratio (w/c) contained a lot of unhydrated ...

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

Aberrant Neural Entrainment to Word‐Level Speech Patterns in Fragile X Syndrome: Evidence for a Statistical Learning Deficit

Autism Research, EarlyView.
ABSTRACT Fragile X syndrome (FXS), the most common inherited cause of intellectual disability and autism spectrum disorder, causes significant language and cognitive impairments. Statistical learning refers to the ability to extract patterns from sensory input through mere exposure and plays a central role in language acquisition.

Efficiency Evaluation of the Ejector Cooling Cycle using a New Generation of HFO/HCFO Refrigerant as a R134a Replacement

Energies, 2018
Theoretical investigations of the ejector refrigeration system using hydrofluoroolefins (HFOs) and hydrochlorofluoroolefin (HCFO) refrigerants are presented and discussed. A comparative study for eight olefins and R134a as the reference fluid was made on

Visual Responsivity in Autism: Measuring Visual Responses in Autistic and Non‐Autistic Adults Using Psychophysics, fMRI, and EEG

Autism Research, EarlyView.
ABSTRACT Autistic individuals frequently report heightened sensitivity to visual stimuli, often described as discomfort in environments with bright or flickering lights. These experiences are hypothesized to reflect underlying differences in sensory gain or neural hyperexcitability; however, findings across studies have yielded mixed results, likely ...

Entrainment characteristics of fine particles under high speed airflow

EPJ Web of Conferences, 2017
Fine silicon particles (mean size of 2.7 μm) are used as entrained materials, and the entrainment characteristics of fine particles are investigated in a cylindrical fluidized-bed (inner diameter of 28 mm and height of 1000 mm) under high speed airflow ...
