Plant small RNAs are 3' methylated by the methyltransferase HUA1 ENHANCER1 (HEN1). In plant hen1 mutants, 3' modifications of small RNAs, including oligo-uridylation (tailing), are associated with accelerated degradation of microRNAs (miRNAs). By sequencing small RNAs of the wild type and hen1 mutants from Arabidopsis thaliana, rice (Oryza sativa), and maize (Zea mays), we found 3' truncation p...
The purpose of this study was to assess heavy metal contamination and health risks for residents in the vicinity of a tailing pond in Guangdong, southern China. Water, soil, rice, and vegetable samples were collected from the area in the vicinity of the tailing pond. Results showed that surface water was just polluted by Ni and As, while groundwater was not contaminated by heavy metals. The con...
The effect of rising damp on the Thermal-hydro-mechanical (THM) behavior Unstabilized Rammed Earth (URE) structures has been rarely studied in literature. To consider this effect, we use a validated theoretical framework implemented finite element code for THM URE materials. is then investigated and compared with same wall not influenced by damp. simulation results show that time plays positive...
Fungal infections and diseases predominantly affect patients with deregulated immunity. Compelling experimental and clinical evidence indicate that severe fungal diseases belong to the spectrum of fungus-related inflammatory diseases. Some degree of inflammation is required for protection during the transitional response occurring temporally between the rapid innate and slower adaptive response...
BACKGROUND Numerous studies confirm the association between exposure to indoor air dampness and molds and different health outcomes. Of these, upper respiratory tract problems are the most commonly reported work-related symptoms in damp indoor environments. The aim of this study was to describe a clinically investigated patient series with occupational rhinitis induced by molds. METHODS Nasal...
Cemented tailings backfill is widely used in worldwide mining areas, and its development trend increasing due to the technical economic benefits. However, there no reliable simple machine learning model for prediction of compressive strength. In present study, research process use artificial intelligence algorithms predict strength cemented tailing was conducted, overcoming shortcomings traditi...
The paper presents a new effective method to damp subsynchronous resonance (SSR) – shaft torsional oscillations for large synchronous generators. This is achieved by using a dynamic power filter and static compensator (DFC) scheme. The proposed scheme with a switched series capacitor compensation and a modulated Tuned-Arm-Filter can be used to damp SSR oscillation modes using a novel Tri-loop E...
In the flotation process, the concentrate grade and the tailing grade are crucial technical indices which reflect the product quality and efficiency. There are strong nonlinearity and uncertainty in such technical indices dynamic behaviors, which can hardly be described using accurate mathematical model. The technical indices which cannot be measured online continuously vary with boundary condi...
