Dental caries is a multifactorial disease with high prevalence around the world. Various strategies have been developed and proved beneficial in managing the disease; however, novel techniques have also been investigated. One of such strategies involves the administration of polyclonal antibodies (passive immunization), usually in the form of an oral mouthwash. While many studies have […]
In response to the problems of high energy consumption, high maintenance costs, and significant environmental impact in traditional sludge treatment schemes, strict control of conditions is required. This study investigates the effect of different raw materials, water temperatures, additives, and physicochemical pretreatments on the hydrothermal carbonization and tempering of sludge through hydrothermal reactions. The experimental […]
Ethanol steam reforming was studied over Ni/MgAl2O4–CeO2 catalysts. The catalysts were prepared using different impregnation media (ethanol or water) and Ni precursors (nitrate or acetate). The use of an alcoholic solution did not affect the specific surface area, but promoted the NiO formation reducible at lower temperature affecting the Ni-support interactions and the Ce3+/Ce4+ initial ratios. All […]
This study aims to probe the clinical efficacy of the nursing intervention of ceftazidime tazobactam sodium combined with Levofloxacin in treating heart failure complicated with lung infection in elderly patients. Patients in the control group (n = 59) accepted ceftazidime tazobactam sodium injection (3:1). Patients in the observation group (n = 59) were given levofloxacin […]
Objective: To investigate the effect of metformin treatment on multiple cytokines and oxidative stress in type 2 diabetes mellitus (T2DM) patients. Methods: The 130 newly diagnosed T2DM patients were randomly divided into an observation group and a control group, with 40 cases in each group. The patients in the control group was treated conventionally, and […]
In this research, photocatalysis single AlF3, Ternary PVC/Al2O3/AlF3 (PNA) and polyaniline (PAI) supported PNA nanocomposite were synthesized by co-precipitation method. Surface area and morphological structure of the synthesized photocatalysts were characterized by X-ray Diffractometer (XRD), Brunauer-Emmett-Teller (BET), and Scanning Electron Microscopy (SEM). With the best conditions, the response in the glassy carbon electrode (GCE) showed […]
Due to the lack of phenol hydroxylation activity of common catalysts, the conversion rate is low, which cannot meet the application requirements. The effect of magnesium ferrite on the high selective phenol hydroxylation catalyst is proposed. Based on the analysis of the synthesis route of phenol, the related mechanism and influencing factors are obtained according […]
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 […]
