2018/11/10/ · The polarization resistance values were used to calculate the inhibition efficiency (η %) via the expression [60]: (1) η (%) = 1-R p 0 R p i × 100 where R p o is the polarization resistance of steel reinforcement (in Ω.cm 2) in the absence of EG/AgNPs and R p i is the polarization resistance of steel reinforcement (in Ω.cm 2) in the
2020/4/24/ · Livestock production residues are commonly used as substrates in agricultural biogas plants for energy recovery. Cattle and poultry manure can be converted to biogas in farm-scale or centralized biogas plants to produce heat and power. This study investigated batch anaerobic digestion of chicken manure coupled with a biological pre
2019/5/1/ · 1. Introduction. In Japan, the annual production of swine manure (or swine wastes) is around 22–23 million tons (MAFF, 2013).Most probably due to the environmental problems and energy crisis, anaerobic digestion (AD) has been applied as a cost effective and environmentally friendly method to recover bioenergy from organic solid wastes

Ruirong Li, a,b Wei Kong, a Yongsheng Chen, a, * Jie Cao, a Pengjun Wang, a Haoli Qu, a Baihe Han, a and Liang Cai b, * Rice straw bales and fresh pig manure were used as feedstock, and added microbial
2023/3/8/ · Livestock manure is a major carrier that stores and transmits antibiotic resistance genes (ARGs). The aim of this study was to identify the crucial environmental factors that result in the change in relative abundance of ARGs and MGEs to explore effective to reduce the occurrence of ARGs. The abundance of ten ARGs and
2014/10/6/ · Faeces from antibiotic-free cows helps resistant bacteria to flourish in soil, puzzling researchers. Pseudomonas bacteria in soil benefit from manure fertilizer
2023/8/1/ · Antibiotic resistance ontology (ARO) was the main means to identify ARGs in sequence database. 4177 genset were assembled and annotated to get 1018 subtypes of ARGs during composting from all the samples. 53 subtypes of ARGs against 22 types of antibiotics were found in samples from all three treatments throughout the composting
2024/3/10/ · The integration of a microbial electrolysis cell (MEC) is an effective strategy for enhancing the efficiency and stability of an anaerobic digestion (AD) system for energy recovery from waste-activated sludge (WAS). Typically, electrodes are arranged as separate components, potentially disrupting mixing and complicating the reactor configuration,
2020/2/1/ · The degradation rate of lignocellulose and methane (CH 4) content must be improved through anaerobic fermentation process engineering in order to promote the proper operation of anaerobic organic waste removal without secondary pollution and low cost.The present study investigates mesophilic anaerobic fermentation of dairy manure
2020/8/1/ · The emergence and spread of antimicrobial-resistant bacteria (ARB) and antimicrobial resistance genes (ARGs) are a global public health concern. ARB are transmitted directly or indirectly from
2022/1/20/ · Corrosion resistance. The representative cyclic potentiodynamic polarization (CPP) curves of W-316L, SLM-316L, and SLM-316L/CrN in 3.5 wt% NaCl are presented in Fig. 5a–c.The breakdown potential
2018/1/29/ · This work presents an experimental validation that an ultrafine grained (UFG) structure of binary Fe-Cr alloys fabricated by severe plastic deformation (SPD) can bring about dramatic improvements in the corrosion resistance. More specifically, UFG Fe-Cr alloys with subcritical chromium content for passivation (8% and 10% Cr) was found to …
2024/6/1/ · The absorption band at 3747 cm −1 refers to stretching the non-bonded -OH group. This also signifies the alcoholic and phenolic -OH stretching. The strong and broad spectra that appeared around 3387 cm −1 confirm the presence of -NH 2 (amine) and -OH (alcohol) groups (Muthulakshmi et al., 2023).The weak band at 2910 cm −1 refers to the …
