Chloroplast DNA probes were used to deduce molecular systematics of 19 Malus species by RFLP analysis. Phylogenetic trees divided these genotypes into 3 groups of cytoplasmic relatedness depending upon the probe. The data indicated maternal inheritance of chloroplast DNA in apple. The species from one...
The maximum temperatures of thermocouples, temperature-sensitive paints, and calorimeters exposed to flames in wildland fires are often called AS Bova,MB Dickinson - 《Revue Canadienne De Recherche Forestière》 被引量: 97发表: 2008年 Thermal imaging by atomic force microscopy using thermocouple cantile...

DETROIT (AP) — Over 30 million air bags in more than 200 models from 20 car and truck makers are being investigated by a U.S. safety agency because they have the potential to explode and hurl shrapnel.
Semiconductor nanocrystals are used to functionalize atomic force microscope (AFM) tips. Such tips may be useful for fluorescence resonance energy transfer (FRET) microscopy. CdSe/ZnS nanocrystals are chemically bound to the surface of an AFM tip by three coating methods utilizing organosilane linker ...
and their isotopes are used to seek a simple explanation for the difference between the C-12/C-13 ratios observed in the interstellar medium and the solar system and for the spatial gradients exhibited by the N/H and N/O ratios in spiral galaxies that are not exhibited by the C-12/C-...
Implantable multi-channel microelectrode probes are the most widely used tool to record neural signals at single-neuron, single-spike resolution and have provided profound insights into neural information processing4,5,6. Combining optogenetic stimulation with multi-channel electrical recording can allow ...
The CellTracker fluorescent probes have been designed to freely pass through cell membranes; however, once inside the cell are transformed into cell-impermeant reaction products. The CellTracker fluorescence probes (except for CellTracker Deep Red) contain a chloromethyl or bromomethyl group that react...
