Our main aim in this paper is to contribute towards a better understanding of the epistemology of absence-based inferences. Many absence-based inferences are classified as fallacies. There are exceptions, however. We investigate what features make absence-based inferences epistemically good or reliable. In Section 2 we present Sanford Goldberg’s account of the reliability of absence-based infer...

OBJECTIVE This study aims to explore the risk factors, profiles and neonatal outcomes of Cesarean sections among selected women in Oman. METHODS In this hospital-based case-control study, a total of 500 participants (250 cases who had cesarean section and 250 controls who had spontaneous vaginal delivery), were randomly selected from four hospitals. Cases and controls were matched according t...

A method for determining the photo excitation reaction cross section of at gamma energy is investigated. HPCe detector used to measure absolute activity induced, producing a practical value calculating average section. Which found be (0.6683) ub matching expected theoretical value.
 This work may considered pioneer measurements such – section.

The neotropical genus Potamium as described by Mitten (1869) included species that had little more in common than a growth form adapted to a semi-aquatic habitat. Brotherus divided the genus in section Eu-Potamium and section Potamiopsis, based on peristome characters. This study shows that all species of section Eu-Potamium belong to Sematophyllum, including P. lonchophyllum which was designat...
