Recently, sustainable energy consumption has been a significant factor in reducing environmental degradation due to the high economic growth, and this phenomenon demands more attention of scholars policymakers. Thus, current literature examines impact factors such as foreign direct investment (FDI), inflation, population growth on (SEC), particularly renewable (REC) China. This study used secon...

drying properties of high moisture potato slices with initial moisture content of about 4.06 (db) under thin layer fixed, semi fluidized and fluidized bed conditions were studied. drying air temperatures of 40, 50, 60 and 70°c were applied in experiments using a laboratory fluidized bed convective dryer. in order to predict the drying behavior of potato slices, seven thin layer drying models we...

Accurate prediction on energy consumption in machining is helpful to evaluate process energy characteristics and choose process methods for energy saving. Specific energy consumption expresses the required energy consumption when cutting unit volume material. The Back Propagation (BP) neural network prediction method for specific energy consumption in machining is set up in the paper. The predi...

the our purpose of objective is evaluation and comparison the energy flow in wheat lands of cities in alborz province. we try to calculate the indexes of energy ratio, gross energy, specific energy, energy efficiency, energy intensity, total input and output energy. population of the study consisted of farmers of cities in alborz province in the year of 1391-92. it was a best way that we use po...

densification of biomass material that usually has a low density is proper way to increasing density,reduce transportation cost and simplify storage and distribution of these materials. pellet productionusing extrusion process is a common method for densification. the goal of this research isoptimization of specific energy consumption for extrusion process considering its effect on pelletdensit...

For improving energy efficiency of machining process, extensive studies focused on how to establish consumption model and optimize cutting parameters. However, the existing methods lack a systematic method promote widespread use in industry. This paper proposes integrating model, experiment design, multi-objective optimization model. Firstly, is established considering non-cutting energy. Then,...

in this paper, non parametric data envelopment analysis (dea) was subjected to the energy data of wheat producers in punjab state, india, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. the main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...

Access to clean water and sanitation is one of the Sustainable Development Goals (SDGs), a global action plan agreed upon by world leaders. Water demand increasing every year. As much as 97% on earth seawater, which requires desalination technology convert seawater into freshwater that will be used meet daily human needs. It necessary continue develop environmentally friendly treatment overcome...

Economic and environmental costs are assessed for four different plastics manufacturing processes, including cold hot runner molding as well stock upgraded material extrusion three dimensional (3D) printers. A larger 3D printer was found to provide a melting capacity of 14.4 ml/h, while smaller with an extruder had 36 ml/h. printing at these maximum capacities resulted in specific energy consum...
