includingE. pyrifoliaeandE. tasmaniensis. Therefore, these data have led us to speculate that human activities related to antimicrobials, xenobiotics, heavy metals, or other compounds have a great potential to contribute to the transfer of these genes toE. amylovora, eventually conferring genetic div...
The invention provides a method of coating a substrate with a coating composition comprising at least two types of functional polysiloxane compounds selected from epoxy-functional polysiloxanes, amino-functional polysiloxanes, and particular adhesion promoting agents of the polysiloxane type. The present ...
A variety of anti-estrogenic substances have been examined for their direct and indirect effect on the binding of [ 3H]-estradiol with uterine cytoplasmic receptors. A distinct separation of the compounds into 2 classes of inhibitors was observed. The non-steroidal anti-estrogens and the C 19 st...
Characterisation of aroma active compounds in black truffles (Tuber melanosporum) and summer truffles (Tuber aestivum) by gas chromatography–olfactometry The aromatic composition of two different species of truffles (black and summer) was evaluated by gas chromatography–olfactometry (GC–O). Volatiles...
- Pure substances can be classified into two main types: elements and compounds. 3. Elements: - Elements are substances that consist of only one kind of atom. - They cannot be broken down into simpler substances by physical or chemical methods. - Examples of elements include: - Metals: ...
