As one of the fast-growth wood species, hybrid yellow poplar (YP-h, Liriodendron sino-americanum) has been extensively planted throughout China, however, little is known about its properties and applicability in structural nonstructural applications such as construction furniture. The aim this study was to evaluate YP-h examine differences with (YP, tulipifera). average vessel diameter (55 μm)...

where D−y is the Liouville right-sided fractional derivative of order a Î (0,1) of y and h >0 is a quotient of odd positive integers. We establish some oscillation criteria for the equation by using a generalized Riccati transformation technique and an inequality. Examples are shown to illustrate our main results. To the best of author’s knowledge, nothing is known regarding the oscillatory beh...

The essential oil of locally available Trachyspermumammi(ajowan) seeds was obtained through hydrodistillation. Its chemical composition analysed by gas chromatography mass spectrometry (GC-MS). Twenty - two compounds EO were identified with the help NIST library. Thymol (38.5%), ρ-cymene (27.2%) and γ-terpinene (26.8%) as major components. Furthermore, its antioxidant power IC50 value 65.3 μ...

— We prove Jtn {D[*) £ M (£>!*), where I>î* is the one-sided Dyck language, and discuss some old and new resuits concerning Pétri net languages. The above resuit shows that Pétri nets without X-labeled transitions are less powerful thon gênerai nets as regards their firing séquences since the class S£\ of gênerai Pétri net languages {Hack [13]) is identical with Aî^D'?), and the class ^Sf^ of c...
