natural rubber/fiber composites were prepared in a laboratory mixer using new and waste short nylon fiber by a one-step mixing process. fiber loading and bonding agent effects on the microstructure and mechanical properties of the composites were studied. the cure characteristics of composites were investigated by using rheometer. cure and scorching times of the composites decreased while maxim...

employees’ satisfaction based on their physical environment is an important factor that can improve employees’ performance, job satisfaction, and organizational productivity in office buildings. occupants’ environmental satisfaction are related to 10 different characteristics, including thermal comfort, air quality, lighting, acoustic quality, office layout, workspace furnishing, cleanliness an...

Beet pulp as component of cattle feed can be processed in different way. Tis study was performed to characterize the physical properties of so called fine beet pulp (FBP); normal beet pulp (NBP) and pelleted beet pulp (PBP). The following parameters were determined: bulk density, kinetics of hydration, functional specific gravity (FSG), water holding capacity (WHC), soluble dry matter and intri...
