A new one-dimensional clarifier model was developed, including components of existing models, and extended with a height-dependent cross-sectional area and two flowrate-dependent dispersion coefficients. This model is evaluated using data from a detailed one-month measuring campaign on a full-scale wastewater treatment plant. The data included hourly sludge concentration profiles, sludge bed he...

Click trains were generated with first- and second-order statistics following Kaernbach and Demany [J. Acoust. Soc. Am. 104, 2298-2306 (1998)]. First-order intervals are between successive clicks, while second-order intervals are those between every other click. Click trains were generated with a repeating alternation of fixed and random intervals which produce a pitch at the reciprocal of the ...

Modified atmosphere packaging (MAP) was used to increase the shelf life of fresh in hull pistachio nuts (Pistacia vera L.), meeting the market demand for fresh high quality products. Fresh in hull pistachio nuts were stored at 5°C and three different gaseous conditions including 10% O2, 20% CO2 and 70% N2 (MAP1), 100% CO2 (MAP2) and ambient atmosphere for 42 days. The samples of 300 g of pistac...

in order to investigate the effects of super absorbent polymer application on reduction of drought stress to corn, a split plot arrangement based on randomized complete block design with three replications was conducted at research field of agriculture faculty of ferdowsi university of mashhad during growing season of 2010-11. the main plot treatments were 1) application of 40 kg.ha-1 super abs...

Motor operated valves (MOV) are one of the most numerous classes nuclear power plant components. An important issue concerned with MOV diagnostics is lack in-process (online) automated control for technical condition during full operation NPP unit. In this regard, a vital task that based on signals current and voltage consumed ‘opening’ ‘closing’ operations. The represent time series measured a...

We find a plethora of new analytic black holes and globally regular horizonless spacetimes in three dimensions. The solutions involve single real scalar field $\ensuremath{\phi}$ which always admits magneticlike expression proportional to the angular coordinate. metrics, satisfy ${g}_{tt}{g}_{rr}=\ensuremath{-}1$ represent continuous generalizations Ba\~nados-Teitelboim-Zanelli (BTZ) one, solve...
