In Sárközy (2001) the third author of this paper presented two conjectures on additive decomposability sequence ”smooth” (or ”friable”) numbers. Elsholtz and Harper (2015) proved (by using sieve methods) second (less demanding) conjecture. The goal is to extend sharpen their result in three directions by a different approach (based theory S-unit equations).

Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...

Three new hypogean species of the Iberian genus Roncocreagris Mahnert, 1974 are described from mainland Portugal: R. borgesi sp. nov. and R. gepesi sp. nov. from caves in the Sicó massif, and R. occidentalis sp. nov. from caves in the Montejunto and Cesaredas karst plateau. This brings to nine the number of known hypogean species of the mostly Iberian genus Roncocreagris: five from Portugal and...

A new species of freshwater crab of the genus Microthelphusa Pretzmann, 1968, from Guyana, South America is described. Microthelphusa meansi, new species, was collected from a remote isolated cloud forest in the Wokomung Massif, a tabletop mountain (tepui) in western Guyana at over 1,000 m above sea level. The conspicuous horseshoe-like marginal lobe and the dome-like auxiliar cephalic lobe of ...

nasogastric tube (ng) insertion is a usual technique in any neonatal intensive care unit. this procedure is undertaken for the children who are in need of invasive care. sometimes, the insertion of nasogastric tube in infants with esophagus friable anatomy tissues may have some dangerous side effect, but such problems are not very common. esophageal perforation is a rare but known complication ...

The Khanka Massif forms the easternmost part of Central Asian Orogenic Belt (CAOB) and represents an ideal location for examination timing processes involved in transition from Palaeo-Asian to Palaeo-Pacific Ocean tectonic systems. However, it is obstructed because late Palaeozoic attributes eastern margin this massif remain unclear. In paper, we provide zircon U-Pb ages Hf isotopic, as well wh...
