suckers are strong sinks of water and nutrients, thus they have intensive competition with plant vegetative parts like scion of budded seedlings. this is an enormous problem of citrus nurseries in north of iran. as far as vast input and time is spending on control of these unwanted suckers. this research, that carried out in design, compares 10 different sucker control methods in three citrus r...

A new pressure measurement technique for measuring the pressure over rotating blades of industrial axial flow fan is described in this paper. The new technique is called pressure sensitive foil (PS-Foil) technique. In this technique a very thin aluminum foil is coated with pressure sensitive paint using anodization method. The resulting PS-Foil can be stick over any existing blade using a very ...

‘THEUSE of heavy aluminum foil in our ashing procedure for PB1 (1), introduced 3 years ago, has proved extremely successful in preventing cross-contamination. A Temco double-door muffle furnace is used for which three steel buckets were made; small buckets, 4 in. wide, 6 in. long, and 6 in. deep, and one large bucket, 6 in. wide, 8 in. long, and 6 in. deep. A steel shovel was made to aid the te...

in this study, the performance of electro-coagulation in combination with aluminum sacrificial anode, in removal of zinc and copper has been investigated. several parameters, such as pollutant concentration, ph, electrical potential, cod, turbidity and contact time were studied to achieve a higher removal capacity. variable concentrations (5-50-500 ppm) of zinc and copper solutions were prepare...

From 1999 to 2006 the NASA Stardust mission collected cometary particles from the Wild 2 comet and interstellar dust from the interstellar medium in two collectors made from aerogel tiles and aluminum foil. By studying their isotopic compositions, these particles can provide us with information about nucleosynthetic processes in stars. Both collector trays are being studied for traces of these ...
