various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. the objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

conclusions approximately one quarter of premature neonates had early mortality, which can be predicted by low gestational age, low birth weight, low apgar score, need to intensive supports, postpartum complications, multiple gestation and history of maternal illnesses. objectives we aimed to determine mortality rate and its main indicators among premature neonates in our region with the aim of...

the acute intravenous toxicities of a selection of three potential long-acting local anaesthetics belonging to the series of2- phenoxyethyldialkylamine were determined in mice. two of the compounds were tertiary amines and the third a quaternary ammonium derivative.the i.v. median lethal dose, (ldso) of one of the tertiary compounds, 21a [n, n- diethyl-2- (2,6- diisopropyl) ethyl amine hydrochl...

Though economic growth has improved in recent years in Nigeria, there has been no evidence of significant manufacturing exports. A critical input that enables capacity for export is investment in technology especially at the firm-level. This study investigates investment in technology by firms in Southwest Nigeria and how technology investment related factors affect the export potential of firm...

We introduce average cost optimal adaptive policies in a class of discrete-time Markov control processes with Borel state and action spaces, allowing unbounded costs. The processes evolve according to the system equations xt+1 = F (xt, at, ξt), t = 1, 2, . . . , with i.i.d. R -valued random vectors ξt, which are observable but whose density ̺ is unknown.

The partnership between banks and non-banks is one of the oldest and most common lateral business partnerships. While banks are looking for new markets and for cost efficient ways to implement new business models, SMEs presumably have considerable efficiency potentials within their financial processes. Some of these potentials could be realized by embedding functionality provided by banks withi...
