TL;DR: A major problem with the Si-based MEMS technology is that Si has poor mechanical and tribological properties as discussed by the authors, which makes it unsuitable for MEMS devices, and therefore it is not suitable for them.

01 Jan 2000TL;DR: In this article, the authors proposed two principles related to the volumetric methods: the direct volume estimation of settled plankton and the measurement of the amount of water displaced by the plankton.
Abstract: Publisher Summary The determination of the total plankton biomass or biovolume is rapid compared with the enumeration and identification techniques. Many samples can be processed in parallel. These measurements are suitable for mixed samples as well as for samples of selected individual species. There is a wide variety of biovolume and biomass measurements. The effort involved in sample treatment increases within the conventional methods and is generally large in biochemical procedures. The methodological bias decreases stepwise: when the amount of excess and interstitial water is reduced by measuring displacement volume or wet mass instead of settled volume, when body fluids are totally removed during dry mass determination, and when the inorganic substances are subtracted. Volumetric methods are the only choice if the samples are to be used for species identification as well. Volumetric methods are also recommended as a quick-look procedure; that is, on board a ship, and in cases where no microbalance or other sophisticated equipment is available. There are two principles related to the volumetric methods: the direct volume estimation of settled plankton and the measurement of the amount of water displaced by the plankton. The first method is more gentle but less precise.

TL;DR: In this paper, the potential use of wood-based biochar (WB) for the removal of potentially toxic elements (PTEs) from water and wastewater has been discussed, and a review demonstrates the overarching scientific opportunities for a comprehensive understanding of using WB as an emerging biosorbent and a promising low-cost and effective material for the remediation of contaminated water.
Abstract: Recently, biochar has received significant attention, especially for the removal of potentially toxic elements (PTEs) from water and wastewater. No review has been focused on the potential use of wood-based biochar (WB) for the removal of PTEs in water and wastewater. Here, we have critically reviewed the (i) preparation and characterisation of WB; (ii) removal efficiency of WB for PTEs in water with respect to its physicochemical characteristics, biochar/water ratio, pH, and sorption system; (iii) removal mechanisms of PTEs by WB; (iv) fate of the sorbed PTEs onto WB; and (v) recovery of the sorbed PTEs from the resultant sludge of WB. We also discussed the removal of PTEs by engineered/designer WB as compared to pristine WB. This review demonstrates the overarching scientific opportunities for a comprehensive understanding of using WB as an emerging biosorbent and a promising low-cost and effective material for the remediation of PTEs contaminated water.

TL;DR: In this article, surface sediment samples from the eastern South Atlantic Ocean including the Walvis Ridge, the Angola and Cape basins, and the Southwest African continental margin were analysed for their benthic foraminiferal content to unravel faunal distribution patterns and ecological preferences.

TL;DR: A hypothesis on the physiological conditions of consciousness is presented and it is assumed that neural assemblies instantiate mental representations; hence consciousness depends on the rate at which large active assemblies are generated.
