Background Amomum compactum is one of the basic species of the traditional herbal medicine amomi fructus rotundus, with great pharmacology effect. The system position of A. compactum is not clear yet, and the introduction of this plant has been hindered by many plant diseases. However, the correlational molecular studies are relatively scarce. Methods The total chloroplast (cp) DNA was extrac...

We define a compactum X to be AB-compact if the cofinality of the character χ(x, Y ) is countable whenever x ∈ Y and Y ⊂ X. It is a natural open question if every AB-compactum is necessarily first countable. We strengthen several results from [Arhangel’skii and Buzyakova, Convergence in compacta and linear Lindelöfness, Comment. Math. Univ. Carolin. 39 (1998), no. 1, 159–166] by proving the fol...

Teleost fish skin is a multifunctional natural material with high penetration resistance owing to specialized puncture mechanisms of both the individual scale and the intact scaled integument. In this paper, we explore the possible additional role of the skin in fish undulatory locomotion by examining the structural and mechanical properties of the dermal stratum (s.) compactum layer of striped...

(+)-cis-Sabinene hydrate and (+)-trans-sabinene hydrate are the main monoterpenes found in marjoram (Origanum majorana), but can also be found in other Origanum species as well, as in e.g. Melaleuca alternifolia. The synthesis of sabinene hydrate in marjoram (Origanum majorana) is performed by sabinene hydrate synthase. It is claimed, that both, (+)-cis- and (+)-trans-sabinene hydrate are produ...

Let X be a compactum such that dimQ X ≤ n, n ≥ 2. We prove that there is a Q-acyclic resolution r : Z −→ X from a compactum Z of dim ≤ n. This allows us to give a complete description of all the cases when for a compactum X and an abelian group G such that dimGX ≤ n, n ≥ 2 there is a G-acyclic resolution r : Z −→ X from a compactum Z of dim ≤ n.

Plants constitute a major resource used for subsistence by people. Ethnobotany plays an important role in preserving plant diversity and understanding interpreting the knowledge that allows plants to be effectively sustainably meet people's needs. Indeed, medicinal are therapeutic is frequently mobilized populations treatment of various diseases physiotherapy. In this study, based on 394 questi...
