Vapor recompression and bottom flashing are among the developed technologies for enhancing energy efficiency of distillation processes. In this paper, a novel configuration of bottom flashing system is proposed for enhancing energy efficiency of dual columns such as direct distillation sequences. The system is designed to operate between two distillation columns. The proposed system engages […]
Currently, the spread of soil oil pollution has had adverse effects on human and the environment due to using fossil fuels in industrial zones. This study was conducted to identify indigenous bacteria from the soil polluted with petroleum com-pounds in order to reduce polluting hydrocarbon compounds. Agar culture medium was used for the growth of […]
The aim of this special was to explore the establishment of epidemic management system and the effect of epidemic prevention and control in general hospitals.The epidemiological data of emergency, outpatient, inpatient and hospital staff were selected as the study subjects. These data were divided into control group (n=7895) and observation group (n=4171) according to the […]
Asphalt pavement will inevitably face the problems of thermal aging and ultraviolet aging, so in order to improve the aging performance of asphalt and improve its service life, the modified asphalt based on nano organic monundedillonite and silica is proposed. Compared with the matrix asphalt, the penetration, ductility, softening temperature, and viscosity of modified asphalt […]
Zn0.3Fe0.45O3 bimetallic oxide nanoparticle (ZnFeBONp) was synthesized and characterized by FESEM, EDS, XRD, BET, TEM and FT-IR techniques with the aim of exploring its application for removing of Congo red dye from waste samples. The effects of pH, contact time, adsorbent dosage and dye concentration on the removal of dye were investigated and optimized as […]
This study aimed to probe the influence of dexmedetomidine in association with sevoflurane anesthesia on postoperative pain and recovery in elderly lower limb fractures patients. A total of 120 elderly lower limb fractures patients received surgery were chosen and separated into control group (CG) and observation group (OG) following the random stratified sampling method. The […]
Anorthite is a rare compositional variety of plagioclase. This mineral is a type of calcium-rich plagioclase feldspar which has great properties such as low thermal expansion coefficient and high modulus of rupture. Therefore, physical properties of hard porcelain bodies will be improved by creating anorthite phase. According to limitation of anorthite natural sources, various sources […]
Cerebral infarction is also called ischemic stroke, is caused by various causes of local brain tissue regional blood supply disorders, resulting in brain tissue ischemic hypoxic lesion necrosis. Pyroptosis has been demonstrated in recent years to be an inflammatory form of programmed cell death. However, the expression of pyroptosis-related genes in cerebral infarction is obscure. […]
Objective: To probe the impacts of whole-process health education based on self-management theory on self-efficacy as well as quality of life in lung cancer patients. Methods: One hundred lung cancer patients undergoing chemotherapy in our hospital from January 2021 to December 2022 were selected and allotted into two groups on the basis of the time […]
This study aimed to elucidate the effect and mechanism of Icariin (ICA) on brown adipose tissue (BAT) and to explore its influence on AS pathological environment in ApoE-/- mice. The primary brown adipocytes were isolated from C57BL/6J mice and treated with ICA in different dosages. ApoE-/- mice were divided to 3 groups: the ordinary diet […]
