Environmental managers and policymakers increasingly discuss trade-offs between ecosystem services (ESs). However, few studies have used nonlinear models to provide scenario-specific land-use planning. This study determined the effects of different future land use/land cover (LULC) scenarios on ESs in Yili River Valley, China, analyzed synergistic response characteristics. We simulated changes ...

Magnetic field effect on local entropy generation due to steady two-dimensional laminar forced convection flow past a horizontal plate was numerically investigated. This study was focused on the entropy generation characteristics and its dependency on various dimensionless parameters. The effect of various dimensionless parameters, such as Hartmann number (Ha), Eckert number (Ec), Prandtl numbe...

The paper is devoted to study the ultrasonic impact on the biomass of natural raw materials, which were used for the creation a nanoporous carbon material (NCM), which was used as electrode material for electrochemical capacitors (EC). The dry shells of apricot seeds were a feedstock, which were modified by the chemical treatment in the phosphoric acid and part of them were impacted by ultrason...

The objective of this study was to formulate and evaluate the drug-polymer interaction of mefenamic acid (MA) using two polymers with different characteristics as ethylcellulose (EC) and/or cellulose acetate phthalate (CAP). Microspheres were prepared by the modified emulsion solvent evaporation (MESE). The effect of drug-polymer interaction was studied for each of microspheres. Important param...

Although high mortality rates have been reported for emphysematous pyelonephritis (EP), information on emphysematous cystitis (EC), which is less common, is sparse. Here, we report one new case of severe EC and 136 cases of EC that occurred between 2007 and 2016, and review information about the characteristics, diagnosis, treatment and mortality of these patients, and the pathogens found in th...

In this paper, we analyze Engineering Changes (EC), which are modifications in forms, fits, functions, materials, or dimensions in components constituting the design. We propose a new approach for processing these changes within a Virtual Collaborative Design Environment. This environment, named Active Distributed Virtual Change Environment (ADVICE) offers an Engineering Change Management solut...

Engineering change (EC) processes often involve many functions and deal with dependencies inside and between products, organizations and production facilities. Therefore, it is complicated and sensitive to disturbances. Lean Product Development is a promising approach for reorganizing product development according to certain principles. The objective of this study was to find possibilities to i...

The concept of human nature played an important role in the Aristotelian attempt to characterize the specific difference of humans from other animals and serves as a normative guide. But with the positivistic turn in the modern conception of nature and the denaturalization of reason (typically since Kant), the essential characteristic of human beings can no more be thought of as "natural". The ...

Rapid prototyping and development of in-circuit and FPGA-based emulators as key accelerators for fast time-to-market has resulted in a need for fast error correction mechanisms. The fabricated or emulated prototypes upon error diagnosis require quick and as much as possible flexible engineering change (EC). However, this problem has recently initiated research activity mainly in the logic synth...
