soil and sludge samples based on it, in addition to the total elemental concentrations (Vercoutere et al., 1995; It is important to evaluate different digestion methods to accurately Quevauviller et al., 1993). In many countries (excluding determine elemental concentrations in soils. Three commonly used digestion procedures, hotplate aqua regia, microwave aqua regia, and the USA), this procedur...

Recently reported synthetic organic nanopore (SONP) can mimic a key feature of natural ion channels, i.e., selective ion transport. However, the physical mechanism underlying the K(+)/Na(+) selectivity for the SONPs is dramatically different from that of natural ion channels. To achieve a better understanding of the selective ion transport in hydrophobic subnanometer channels in general and SON...

Good software architecture is critically important for successful software development. The software architecture can be defined as a set of architectural design decisions. However, the effort for acquiring good software architecture currently lacks of interest and experience in architectural design decisions. For this reason, during acquiring good software architecture, it is difficult to eval...

The title compound, [Co(C3H7NO)(H2O)5]SO4·C3H7NO, contains five aqua ligands, a Co(II) atom, a sulfate ion and both a coordinating and a non-coordinating di-methyl-formamide (DMF) mol-ecule. The DMF solvent mol-ecule lies between the complex units, which are located along the b axis. The sulfate ion is for charge balance. The Co(II) atom has distorted octa-hedral coordination geometry, being li...

Air temperature is a key variable in wide range of environmental applications, including land–atmosphere interaction, climate change research and hydrology crop growth models, among others. The objective this study was to estimate daily maximum (Tmax) minimum (Tmin) temperatures, based on MODIS AQUA/TERRA land surface (LST), NDVI, extraterrestrial solar radiation precipitation data. Artificial ...

The asymmetric unit of the title compound, [Co(C(12)H(6)N(2)O(2))(H(2)O)(4)](NO(3))(2), consists of a Co(II) complex cation with twofold rotational symmetry and two nitrate anions. The Co(II) atom has a distorted octa-hedral geometry with the basal plane occupied by two 1,10-phenanthroline-5,6-dione N atoms and two aqua O atoms, with the other two aqua ligands in axial positions. The aqua ligan...

This study aimed to (a) identify factors that motivate older adults to participate in aqua-based exercise; (b) identify potential barriers; and (c) compare perceptions between older adults with and without osteoarthritis (OA). Fifteen adults above 60 years of age participated in one of three focus groups during which they discussed perceived benefits, motives, and barriers to aqua exercise. Pai...
