this study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by azolla caroliniana.  the experimental investigations have been carried out using azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), ph (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). the maximum removal ...

The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill. Genetic Algorithm is used to estimate the unknown parameters that are used in the model validation. The advantage is that the raw data used in modeling can be obtaine...

Pulp and paper mill situated in the complex terrain of northern Slovakia, in the close vicinity of the city of Ružomberok, continuously releases to atmosphere 30 kg of water vapor per second. Impressive clouds above the industrial complex have given rise to concerns from the side of local citizens, suspecting the emissions to be responsible for the local increase in precipitation. Therefore, a ...

An empirical study of the bivariate probability distribution characterizing a full set of two consecutive price increments x and y for a group of stocks at time scales ranging from one minute to thirty minutes reveals asymmetric structures with respect to the axes y = 0, y = x, x = 0 and y = −x. All four asymmetry patterns remarkably resemble a four-blade mill called market mill pattern. The fo...

A huge number of workers are employed in traditional rice mills where they are potentially exposed to dust. In this study a dust collection system was developed to capture the airborne dust in the rice mill. The feeding and sieving section of the mill was identified as major dust creating zone. The dust was captured by creating suitable air stream at feeding and sieving sections of the mill and...

Phasically active sensory systems commonly influence rhythmic motor activity via synaptic actions on the relevant circuit and/or motor neurons. Using the crab stomatogastric nervous system (STNS), we identified a distinct synaptic action by which an identified proprioceptor, the gastropyloric muscle stretch receptor (GPR) neuron, regulates the gastric mill (chewing) motor rhythm. Previous work ...

Melatonin (MT) is considered as a plant growth regulator, has extensive functions and plays prominent role in ripening fruit senescence. However, there been no report regarding the influence of melatonin on biochemical changes avocado (Persea americana Mill.) during ripening. In this study, cultivar “034” was treated with MT at 0.1 mM 0.5 to evaluate relating quality storage 22 oC ± 1 75–80% re...

Reliable measurements of ball mill load parameters and reorganization of the operating statuses are the key factors for saving energy and optimization control. Empirical mode decomposition (EMD) and partial least squares (PLS) are used to analyze shell vibration signal and monitor mill load parameters of ball mill. The shell vibration signal is decomposed into several intrinsic mode functions (...

A customer who places a tentative order at a steel mill customarily receives a due-date quotation, namely the date by which the mill says that it will ship the order. The steel mill wants the due date to be early enough so that the customer won’t balk (withdraw the order), but late enough so that the probability of tardiness is low. This note obtains expressions for the tardiness probability at...
