Property graphs have reached a high level of maturity, witnessed by multiple robust graph database systems as well the ongoing ISO standardization effort aiming at creating new standard Graph Query Language (GQL). Yet, despite documented demand, schema support is limited both in existing and first version GQL Standard. It anticipated that second Standard will include rich DDL. Aiming to inspire...

We construct a new partial geometry with parameters pg(5,5,2), not isomorphic to the of van Lint and Schrijver.

Over fifty bacterial strains were isolated from seawater samples in the presence of naphthalene as a sole source of carbon and energy. Among them, three isolates with higher growth rate and naphthalene degradation ability were selected for further studies. Biochemical and molecular analysis revealed that two Persian Gulf isolates, strain PG-10 and strain PG-48 belonged to the group of hydrocarb...

Punica granatum (Pg), commonly known as pomegranate (Pg), is a member of the monogeneric family, Punicaceae, and is mainly found in Iran which is considered to be its primary centre of origin. Pg and its chemical components possess various pharmacological and toxicological properties including antioxidant, anti-inflammatory (by inhibiting pro-inflammatory cytokines), anti-cancer and anti-angiog...

We find all minimal blocking sets of size 32 ðpþ 1Þ in PGð2; pÞ for p < 41. There is one new sporadic example, for p 1⁄4 13. We find all maximal partial spreads of size 45 in PGð3; 7Þ. 1 Minimal nontrivial blocking sets in PG(2, p) A blocking set in a projective plane is a set of points meeting all lines. It is called nontrivial when it does not contain a line. An m-secant of a set is a line me...
