Miscanthus biomass can be used to produce lightweight concrete. However, cell wall polymers leached in the alkaline cementitious medium disturb cement setting. This is case for grass lignin and arabinoxylan due their specific alkali solubility. The main objective of this paper was study impact from miscanthus on hydration Portland by electrical conductivity. To end, dioxan (DL) (AX) were extrac...

In the deca-hydro-phenanthrenone ring system of the title compound, C(27)H(44)O, the two cyclo-hexane rings adopt chair conformations, whereas the cyclo-hexene ring adopts an envelope conformation. The cyclo-pentane ring is twisted. In the crystal structure, mol-ecules are stacked along the a axis, but no significant inter-molecular inter-actions are observed.

Having a sense of self is an explicit and high level-functional specialization of the human brain. The anatomical localization of self-awareness and the brain mechanisms involved in consciousness were investigated by functional neuroimaging different emotional mental states of core consciousness in patients with multiple personality disorder, i.e. dissociative identity disorder (DID). We demons...

In the title compound, C(17)H(15)NO, the dihedral angle between the phenyl rings is 80.1 (2)°. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers.

In the title compound, C(9)H(15)N(3)O(4), the 1,3-dioxane ring displays a chair conformation and the five-membered ring is close to planar (r.m.s. deviation = 0.054 Å). An intra-molecular N-H⋯O hydrogen bond to one of the nitro-group O atoms generates an S(6) ring. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into C(6) chains propagating in [010] and a C-H⋯O link als...

In the title compound, C13H19NO3, the dioxane ring adopts a chair conformation. Its mean plane is inclined to the 4-meth-oxy-phenyl ring by 70.34 (9)°. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds, forming inversion dimers with an R (2) 2(16) ring motif. The dimers are linked via C-H⋯π inter-actions, forming two-dimensional networks lying parallel to the ac plane.
