On Phase-I monitoring of process location parameter with auxiliary information-based median control charts
(
MDPI AG
, 2020 , Article)
A control chart is often used to monitor the industrial or services processes to improve the quality of the products. Mostly, the monitoring of location parameters, both in Phase I and Phase II, is done using a mean control ...
On designing a sequential based EWMA structure for efficient process monitoring
(
Taylor and Francis Ltd.
, 2020 , Article)
Control chart is a popular technique that is widely used in statistical process control to identify any possible deviations from a stable state of a process. Shewhart charts are famous for identifying larger shifts, while ...
Microbially induced calcite precipitation in calcareous soils by endogenous Bacillus cereus, at high pH and harsh weather
(
Elsevier
, 2020 , Article)
Microbially induced calcite precipitation (MICP) improves the physical properties of soils by increasing the solid content, decreasing the pore sizes and improving the rigidity of the particle-to-particle contact ending ...
The use of principle component analysis and MALDI-TOF MS for the differentiation of mineral forming: Virgibacillus and Bacillus species isolated from sabkhas
(
Royal Society of Chemistry
, 2020 , Article)
Occurrence of mineral forming and other bacteria in mats is well demonstrated. However, their high diversity shown by ribotyping has not been explained, although it could explain the diversity of formed minerals. Common ...
Delineating the global plastic marine litter challenge: clarifying the misconceptions
(
Springer
, 2020 , Article)
Plastics, owing to their various beneficial properties (durability, flexibility and lightweight nature), are widely regarded as the workhorse material of our modern society. Being ubiquitously and increasingly present over ...
3D synchrotron computed tomography study on the influence of fines on gas driven fractures in Sandy Sediments
(
Elsevier
, 2020 , Article)
Production of methane from hydrate-bearing sediments requires hydrate dissociation for releasing
mobile methane gas in sediments prior to gas production operations. Fines may migrate through or
clog the pore space of ...
Discrepancy in the Critical State Void Ratio of Poorly Graded Sand due to Shear Strain Localization
(
American Society of Civil Engineers (ASCE)
, 2020 , Article)
The critical state (CS) concept is a theoretical framework that models the constitutive behavior of soils, including sand and other granular materials. It supports the notion of a unique postfailure state, where the soil ...
Enhancement of Naphthalene Degradation by a Sequential Sulfate Injection Scenario in a (Semi)-Arid Coastal Soil: a Flow-Through Reactor Experiment
(
Springer
, 2020 , Article)
Engineered sulfate injection has been introduced as an effective technology to enhance the remediation of soil and groundwater contaminated by petroleum hydrocarbons. While some studies indicate that sulfate injection is ...
A feasibility study of utilizing hydrothermal liquefaction derived aqueous phase as nutrients for semi-continuous cultivation of Tetraselmis sp.
(
Elsevier Ltd
, 2020 , Article)
The feasibility of substituting 50% nutrients by aqueous phase liquid (APL), derived from hydrothermal liquefaction of Tetraselmis sp. biomass, in a semi-continuous cultivation of Tetraselmis sp. was studied. Growth ...
Effects of dissolved organic phase composition and salinity on the engineered sulfate application in a flow-through system
(
Springer
, 2020 , Article)
Engineered sulfate application has been proposed as an effective remedy to enhance the rate-limited biodegradation of petroleum-hydrocarbon-contaminated subsurface environments, but the effects of dissolved organic phase ...
