Predicting paper properties based on a limited number of measured variables can be an important tool for the industry. Mathematical models were developed to predict mechanical and optical properties from the corresponding paper density for some softwood papers using support vector machine regression with the Radial Basis Function Kernel. A dataset of different properties of paper handsheets pro...

– 8 – In 1993 and 1994, many crosses were made with the goal of developing rootstocks with broad and durable nematode resistance, while improving horticultural characters such as rooting ability and shoot length. The parents of these crosses included a number of grape species known to be highly resistant to both root-knot and dagger nematodes. They included several forms of Vitis arizonica, V. ...

Fungal endophytes and their grass hosts have attracted growing research interest as systems in which to examine the ecological and evolutionary consequences of maternally inherited symbioses. The lion’s share of research for these endophytic symbioses has been focused on Neotyphodium endophytes in three introduced agronomic grasses (but especially one, tall fescue; see Faeth and Saikkonen 2007;...

Recently, new brake pads have been developed using sustainable materials that are not harmful to the environment. In this study, effect of blue-colored Cupressus arizonica cones was determined as a friction modifier in pad composites. Four different samples were prepared by grinding cone material. The samples’ physical and chemical properties performances compared, finally, their microscopic an...

environmental pollution with heavy metals is a global struggle. phytoremediation is an effectiveand low-cost technology for refinement of polluted soils. this research was conducted in zanjan province(located in north west iran) where metallurgical industries are developed quickly. in this study, based on theheavy metals contamination of soil in the studied area six sampling sites were selected...
