For idealized (spherical, smooth) dark matter halos described by single-parameter density profiles (such as the Navarro–Frenk–White profile), there exists a one-to-one mapping between energy of halo and scale radius its profile. The therefore uniquely determines concentration parameter such halos. We exploit this fact to predict concentrations via random walk in space. Given full merger tree fo...

With the increasingly serious eutrophication of inland water, frequency and scope harmful cyanobacteria blooms are increasing, which affects ecological balance endangers human health. The aim this study was to propose an alternative method for quantification cyanobacterial concentrations in water by correlating multispectral data. research object Erhai Lake, Dali, China. Ten monitoring sites we...

The Çaygören Reservoir was sampled monthly from February 2007 to January 2009 at three stations to determine the relationships between the chlorophyll-a (Chl-a) dynamics and soluble reactive phosphorus (SRP), nitrate-nitrogen (NO3-N), ammonium-nitrogen (NH4-N), water discharge, water transparency, water temperature (T), specific conductance (SC) and pH. Thermal stratification occurred in the re...

24-hour samples of pm1 (submicron particles, aerodynamic diameters ≤1 μm) and pm2.5(fine particles, aerodynamic diameters ≤ 2.5 μm) were collected at a quasi-rural area in racibórz (1 january-30 june 2011). the samples were analysed for carbon (organic and elemental), water-soluble ions (na+,nh4 +, k+, mg2+, ca2+, cl-, no3 -, so4 2-) and concentrations of 21 elements with a carbon analyser (sun...
