Abstract Prevalence of atopic dermatitis (AD) is increasing worldwide. Up to date, there has been no face-to-face nation-wide study in China. We aim explore the prevalence clinical diagnosed AD children aged 1–7 ys Twelve metropolises were chosen from different areas In each region, we selected 4–10 kindergartens and 2–5 vaccination clinics randomly. A complete history-taking skin examination performed by dermatologists. The definite diagnosis severity determined two or three All criteria...
The discovery of a methanogen that can conserve energy to support growth solely from the oxidation organic carbon coupled reduction an extracellular electron acceptor expands possible environments in which methanogens might thrive. potential importance c -type cytochromes for transfer syntrophic bacterial partners and/or Fe(III) minerals some Archaea was previously proposed, but these studies with Methanosarcina acetivorans provide first genetic evidence cytochrome-based . results suggest...
The tremendous acoustic impedance difference between the piezoelectric composite and air prevents ultrasonic transition, resulting in low amplitude for received signal defect detection using an air-coupled transducer. matching system, which includes layers bonding attached to composite, can reduce benefit transition. In this paper, fabrication method modeling are proposed optimize transducer performance. effects of layer material on performance also discussed. Experiments were conducted...
Graphene/Aluminum (Gr/Al) composites with different graphene chirality and distribution patterns were established. The contribution of interfaces to the mechanical properties was investigated by using molecular dynamics methods. strengthen about 10% Young's modulus 5% tensile yield strength compared aluminum. Influenced chiral structures graphene, fracture strain zigzag composite is larger, stress armchair higher. Folding deformation promotes yielding under compressive loading. Even if...
It is known that the physiology of
Impact statement Methane‐producing microorganisms accelerate the corrosion of iron‐containing metals. Previous studies have inferred that some methanogens might directly accept electrons from Fe(0), but when this possibility was more intensively investigated, H 2 shown to be an intermediary electron carrier between Fe(0) and methanogens. Here, we report Methanosarcina acetivorans catalyzes direct metal‐to‐microbe transfer support methane production. Deletion gene for multiheme, outer‐surface...

In this paper, we use MD to simulate the crack propagation behavior of GNG copper models with different grain size gradients, analyze microstructural variations each model and its mechanism.
Klebsiella pneumoniae is one of the most common nosocomial opportunistic pathogens and usually exhibits multiple-drug resistance. Phage therapy, a potential therapeutic to replace or supplement antibiotics, has attracted much attention. However, very few phages have been well characterized because lack efficient genome-editing tools. Here, Cas9 from Streptococcus pyogenes single guide RNA (sgRNA) were used modify virulent bacteriophage, phiKpS2. We first evaluated distribution sgRNA activity...
Waste cooking oil (WCO) is a sustainable alternative to raw vegetable oils and fats for biodiesel production considering both environmental economic benefits. Raw glycerol from WCO-based (GWCO) difficult utilize via biological method, as multiple toxic impurities have inhibitory effects on microbial growth especially pure cultures. In this work, four consortia were selected activated sludge by 30 serial transfers under different conditions. The obtained exhibited lower diversity species...
Nickel-based single crystal alloys have excellent mechanical properties due to its unique two-phase structure and interface. Therefore, molecular dynamics methods were used simulate nanoindentation microstructural evolution. We found the indenter reaction force hardness of Ni3Al phase is largest. The pop-in event in more obvious than that Ni Ni/Ni3Al phase. Because lots dislocations break through barrier interface cut into phase, while only slip inside Moreover, we position starting point...
