rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
Abstract Two different drying methods were applied for dehydration of apple, i.e., convective (CD) and microwave (MD). The process through divergent temperatures; 50, 60 70 °C at 1.0 m/s air velocity three levels power (90, 180, 360 W) studied. In the analysis performance our approach on moisture ratio (MR) apple slices, artificial neural networks (ANNs) was used to provide with a background fu...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
Abstract Grape pomace is a rich source of bioactive compounds and dietary fiber. This study aims to valorize the grape by microwave-vacuum-assisted drying extraction, which novel, green, clean label technology. The extraction from was optimized using response surface methodology. Box-Behnken design used for three process variables, i.e., time, power, vacuum levels. highest rate observed (5.53 g...
Simple innovations in temperature control during cocoa roasting can help improve the quality of chocolate made by small entrepreneurs Andean-Amazonian valleys Peru. The objective this research was to evaluate effect oven on beans (Theobroma cacao) roasting, using six mathematical models. Cocoa amounts 100 and 200 g were placed a tray conventional electric set at 250 °C. A K-type thermocouple wi...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
Drying paddy with low-pressure superheated steam (LPSS) can effectively increase the γ-aminobutyric acid content in paddy. This study aimed to investigate characteristics and mathematical models (MMs) of thin-layer drying LPSS. The experimentally obtained data were fitted by nonlinear regression 5 MMs commonly used for calculate goodness fit MMs. Then, LPSS was modeled two machine learning metho...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Performance of a tractor mounted solar-biomass hybrid dryer which utilise combined energy solar and biomass was investigated. Drying behaviour maize grains in the also investigated using 10 thin-layer mathematical models. The models were compared based on coefficient determination (R2) root mean square error (RMSE) values between experimental predicted moisture ratios. Moisture content (MC) red...
The effect of microwave and blanch pretreatments on the drying kinetics and quality of white yam (Dioscorea rotundata) was investigated. Yam cubes destined for hot air drying at temperatures 70-90°C were predried in a domestic microwave or blanched in hot water for 1-5 min. Microwave pretreatment time had a positive significant effect on drying rate but both pretreatments had a negative influen...
