EDI is an important type of B2B electronic commerce practices. Basing on the result of a successful national research program on EDI, the paper presents the development philosophy and applications of an EDI system focusing on domestic trading. The techniques utilized to achieve high adaptability and flexibility, and the measures adopted to insure high security are discussed in detail.

BAN estimators generally admit first order representations which insure them to be also asymptotically Pitman closest. For AN estimators admitting a first order representation, an ordering under the Pitman closeness measure is established and is shown to be isomorphic to the one under 'the usual quadratic norm. Multiparameter problems are also treated in the same vein.

Three models of plant phyllotaxis are presented. Phyllotaxis is shown to be governed by subtle properties of number which insure that the florets are arranged so as to have the most space and therefore have the greatest access to sunlight. The mathematical tools discussed are Farey series, Wythoff’s game, continued fractions, and a Fibonacci number system called Zeckendorf notation.

BACKGROUND In addition to surfactant deficiency, increase of lung fluid content and secretion of fluid derived from the blood participate in the pathogenesis of RDS in newborns. We hypothesized that the administration of salbutamol (β-agonist) to increase lung fluid absorption would decrease the INSURE failure rate in newborns with respiratory distress syndrome (RDS) treated with intratracheal ...

BACKGROUND In recent years, various noninvasive respiratory support (NRS) of ventilation has been provided more in neonates. The aim of this study was to compare the effect of HFNC with NCPAP in post-extubation of preterm infants with RDS after INSURE method (intubation, surfactant, extubation). METHODS A total of 54 preterm infants with RDS (respiratory distress syndrome) were enrolled in th...

Agriculture is an important sector in Ghana's economy, however, with high risk due to natural factors like climate change, pests and diseases and bush fires among others. Farmers in the Brong-Ahafo region of Ghana which is known as one of the major cocoa producing regions, face these risks which sometimes results in crop failure. The need for farmers to therefore insure their farms against crop...
