The pH scale is used to determine whether a substance is acidic or basic, and to calculate how strong a chemical it is. A pH value is a number that ranges from 1 to 14 for most common chemicals, with seven being the middle or neutral point. Values below 7 are indicators of acidity, ...
, narrowrange, centre-zero meter, the scale changing means is arranged to alter the compensation to make it appropriate to the range being employed and the narrow-range is made adjustable so that its centre zero can occupy any point or one of a selected number of points in the pH scale....
Species’ vulnerability to extinction is strongly impacted by their geographical range size. Formulating effective conservation strategies therefore requires a better understanding of how the ranges of the world’s species have changed in the past, and h
In many species, the offspring of related parents suffer reduced reproductive success, a phenomenon known as inbreeding depression. In humans, the importance of this effect has remained unclear, partly because reproduction between close relatives is both
Distances of 1.5 to 8 nm in macromolecules and supramolecular assemblies can be measured by pulse electron paramagnetic resonance (EPR) experiments. In con... G Jeschke - 《Chemphyschem》 被引量: 74发表: 2015年 pH-Sensitive Radical-Containing-Nanoparticle (RNP) for the L-Band-EPR Imaging of ...
A mill-scale hydrometallurgical experiment (2700 m3 of effluent treated/day) was conducted for three months at the Rabbit Lake uranium mine site located in northern Saskatchewan, Canada, to determine the controls on the solubility of dissolved arsenic over a pH range of 1-11 and to develop a ...
An approach using a liquid-crystal spatial light modulator (LC-SLM) to enlarge the depth measuring range of the projected fringe profilometry is presented. This approach is especially applicable to detect dynamic objects with micro-scale sizes. Compared with a typical 2D image system, the LC-SLM...

Microbial niche breadth has been measured for specific aspects of the environment (for example, temperature15,16, pH17and nutrient dependence18,19). Niche breadth definitions that assess the fulln-dimensional niche space20have been based on occurrence in environmental samples. Rather than the theoreti...
We aimed to determine how the elevation gradient affect the nematode community structure, diversity and contribution to belowground carbon assimilation in the form of metabolic footprint. Our results showed that total nematode abundance and the abundance of different trophic groups (fungivores, herbivores...
