Acoustic emissions from transpiring plants – new results and conclusions
Using Ulmus glabra as an example we revealed that acoustic emissions from plants do not necessarily occur in conjunction with water stress. The waveforms in the various signals show that acoustic emissions may possibly be generated by still unknown hydraulic events, more complex than cavitation. Using a special microscopic technique we established the presence of minute gas bubbles attached fir...
متن کاملFluoride release from three glass ionomers after exposure to sodium fluoride and acidulated phosphate fluoride gels
BACKGROUND Glass ionomer (GI) restorations exposed to fluoride have the ability to slowly release fluoride. Therefore, the aim of this study was to investigate fluoride release from three GIs before and after exposure to sodium fluoride (NaF) and acidulated phosphate fluoride (APF). MATERIALS AND METHODS Fifteen disc-shaped samples (6 mm in diameter and 2 mm in thickness) from three GIs (Fuji...
متن کاملFour new Fusarium taxa isolated from gramineous plants in Iran
In the course of a survey during growing seasons of 2002-04, various fields and pastures in 23 Iranian provinces were sampled. Some 1200 isolates of Fusarium from root, crown, stem and spike of various plants belonging to the family Poaceae were recovered using Nash-Snyder selective medium and purified on potato dextrose agar (PDA). Based on morphological characters, 35 Fusarium species were id...

متن کاملSome New Developments in Small Area Estimation
Small area estimation has received a lot of attention in recent years due to growing demand for reliable small area statistics. Traditional area-specific estimators may not provide adequate precision because sample sizes in small areas are seldom large enough. This makes it necessary to employ indirect estimators based on linking models. Basic area level and unit level models have been extensiv...
