Summary On the basis of wellbore and reservoir heat-transfer process during deepwater drilling, a model between formation is built up for two different conditions: without riser with riser. Wellbore temperature distributions under drilling-fluid-injection temperatures, flow rates, circulating times, drilling depths are simulated by use this model. Taking hydrate-phase equilibrium into consideration, possible region hydrate-formation dissociation analyzed, effective methods proposed to...
Sensitive and simplified detection of a mycotoxin such as deoxynivalenol (DON) is crucial for food safety. In recent years, the CRISPR/Cas technology has demonstrated significant potential in detecting non-nucleic acids. Herein, we present triple enzyme-assisted fluorescence immunoassay (TEFIA) that integrates alkaline phosphatase (ALP)-regulated DNAzyme cleavage with CRISPR/Cas12a assay accurate mycotoxin. By employing this method DON, exhibit low limit 0.05 ng/mL satisfactory linear...
Occurrences of mycotoxins in cereals are widespread throughout the world. However, lack efficient and ultrasensitive tests has largely impeded identification these substances actual samples. Herein, a novel one-pot isothermal assay that integrates rolling-circle amplification (RCA) CRISPR/Cas12a to detect aflatoxin B
The gas–liquid–solid phase transition of hydrates is complex and has effects that are coupled with the heat-mass transfer in reservoirs; thus, this related to determination flow assurance production efficiency. microfluidic technology applied research can simulate a porous medium an alternative conventional sand-packing approach, encompassing real characteristics interfaces between multiple phases, reducing randomness pore shape, mastering distribution channels. hydrate was observed...
Polarized Scanning Atmospheric Corrector (PSAC) onboard the Huanjing Jianzai (HJ)-2 A/B satellites is a cross-track scanning polarimetric remote sensor that measures intensity and direction of light reflected by Earth its atmosphere 9 full polarized spectral bands from near-ultraviolet (near-UV) to shortwave infrared (SWIR). In particular, geolocation accuracy an important factor for polarization observations. An automatic coastline inflection method (CIM) implemented PSAC error estimation....
摘要: 高砷地下水在我国广泛分布,开发绿色高效的除砷材料对于促进地区发展和保障居民饮用水安全具有重要意义.采用共沉淀法结合NaOH水热处理技术制备了二氧化锰改性粉煤灰吸附材料MFA150,并研究其对地下水中As(Ⅲ)和As(Ⅴ)的吸附特性.结果表明,NaOH水热处理破坏了原始粉煤灰的玻璃体结构,且在这一过程中生成沸石相,粉煤灰比表面积由1.30 m2/g增加至40.26 m2/g.在负载MnO2后,MFA150比表面积达到148.82 m2/g.此外,吸附材料表面-OH的含量显著增加,为As(Ⅲ)和As(Ⅴ)提供了更多的吸附活性位点.MFA150对As(Ⅲ)和As(Ⅴ)的吸附过程符合Elovich模型和Freundlich模型.在中性条件下MFA150对As(Ⅴ)和As(Ⅲ)的吸附量分别达到2.55 mg/g和9.71...
Abstract During deep water oil well testing, the low temperature environment is easy to cause wax precipitation, which affects normal operation of test and increases operating costs risks. Therefore, a numerical method for predicting precipitation region in strings was proposed based on pressure fields string calculation model. And factors affecting were analyzed. The results show that: decreases with increase production rate, decrease geothermal gradient, depth drop water-cut produced...
