Cloud computing and web application-based remote real-time monitoring and data analysis: slurry injection case study, Onshore USA

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
Remote live monitoring of field operations, such as injection, has been very restricted, although real-time data are often collected at field sites. The difficulties lie in the data access and limitations to obtain computing resources for data analysis ...

Analysis of the waste selective collection at drop-off systems: Case study including the income level and the seasonal variation [PDF]

open access: yes, 2017
There are several factors which have an influence in the selective collection of the municipal waste. To define a selective collection system, the waste generation pattern should be firstly determined and these factors should be analyzed in depth.

Agricultural Waste [PDF]

open access: yesWater Environment Research, 2015
The management and disposal of agricultural waste are drawn more and more attention because of the increasing yields and negative effects on the environment. However, proper treatments such as converting abundant biomass wastes into biogas through anaerobic digestion technology, can not only avoid the negative impacts, but also convert waste into ...

Beryllium solubility and hydrolysis in dilute to concentrated CaCl2 solutions: thermodynamic description in cementitious systems

open access: yesFrontiers in Nuclear Engineering, 2023
The solubility and hydrolysis of Be(II) was investigated from undersaturation conditions in alkaline, dilute to concentrated CaCl2 solutions (0.05–3.5 M). Experiments were performed with α-Be(OH)2(cr) under Ar atmosphere at T = (22 ± 2)°C.
