New online ecology of adversarial aggregates: ISIS …

Online support for adversarial groups such as Islamic State (ISIS) can turn local into global threats and attract new recruits and funding. Johnson et al. analyzed data collected on ISIS-related websites involving 108,086 individual followers between 1 January 1 and 31 August 2015. They developed a statistical model aimed at identifying behavioral patterns among online supporters of ISIS and ...

Aggregates | Mines & quarries | MineralsUK

Aggregates account for approximately 85 per cent of the non–energy minerals extracted in the UK and, are critical for the national economy. The construction sector relies on the supply of construction aggregates, obtained from 1300 quarries in Britain, dredged from the sea bed by a fleet of 28 marine aggregate dredgers and through recycling.

Strategies for the expansion of human induced …

VWBRs allow the expansion of hiPSCs as aggregates. A protocol for expansion of hiPSCs as aggregates in the VWBRs was adapted from similar reports for other types of bioreactors [].For initial experiments, mTeSR1 was selected as the culture medium, due to being a feeder-free and serum-free medium, which has already been well-documented for the expansion of hiPSCs [28, 29].

Monetary Aggregates - St. Louis Fed

Robert H. Rasche, in articles from 1987 and 1990, produced monetary aggregates for 1948-1958 that are consistent with current Federal Reserve Board definitions. The official measures of the money stock in the United States currently published by the Board of Governors of the Federal Reserve System start with January, 1959.

Mechanisms and Rates of Bacterial Colonization of …

Quantifying the rate at which bacteria colonize aggregates is a key to understanding microbial turnover of aggregates. We used encounter models based on random walk and advection-diffusion considerations to predict colonization rates from the bacteria's motility patterns (swimming speed, tumbling frequency, and turn angles) and the hydrodynamic environment (stationary versus sinking aggregates).

Microstructural Analysis of Iberian Expanded Clay …

This article presents a detailed study of the microstructure of Iberian expanded clay lightweight aggregates (LWA). Other than more commonly used mercury porosimetry (MP) and water absorption methods, the experimental study involves optical microscopy, scanning electron microscopy (SEM), and microtomography (μ-CT).

Anaerobic Nitrogen Turnover by Sinking Diatom …

In the world's oceans, even relatively low oxygen levels inhibit anaerobic nitrogen cycling by free-living microbes. Sinking organic aggregates, however, might provide oxygen-depleted microbial hotspots in otherwise oxygenated surface waters. Here, we show that sinking diatom aggregates can host anaerobic nitrogen cycling at ambient oxygen levels well above the hypoxic threshold.

This is a very small acknowledgement by the Government to the very big and interlinked issues of aggregates sourcing, aggregates transportation and economic development. The chart below (fig. 1) helps to illustrate the situation across the regions of Great Britain (crushed rock is the predominant form of aggregate transported by rail, so sand and gravel has been excluded).

Protein aggregates encode epigenetic memory …

Author summary Since accurate protein folding is crucial for cellular viability, misfolded and aggregated proteins have typically been thought of as detrimental structures with potentially harmful physiological effects. In this report, we show that this general paradigm does not appear to hold in the model bacterium Escherichia coli. We find that the emergence of protein aggregates is mainly ...

Since their inception, human induced pluripotent stem cells (hiPSCs) have held much promise for pharmacological applications and cell-based therapies. However, their potential can only be realised if large numbers of cells can be produced reproducibly on-demand. While bioreactors are ideal systems for this task, due to providing agitation and control of the culture parameters, the common ...
