this study was carried out to determine some mechanical properties of barley seed including deformation, rapture force, rapture energy and toughness as a function of moisture content (10.5%, 12.5%, 14.5% , 16.5%, db), loading rate (5, 15, 25, 35 mm.min-1) and grain size (small, medium, large). tests were performed at 7 replications by the means of a factorial base plot experiment. the results s...

Massively parallel sequencing has revolutionized many areas of biology but sequencing large amounts of DNA in many individuals is cost-prohibitive and unnecessary for many studies. Genomic complexity reduction techniques such as sequence capture and restriction enzymebased methods enable the analysis of many more individuals per unit cost. Despite their utility, current complexity reduction met...

Background: Premature rupture of the membrane (PROM) is a major cause of preterm birth, and the mechanisms still not fully defined. However, the mechanisms for PROM still not fully defined. This study investigated the roles of p38 in regulation the expression of MMP-9 and TIMP-1 in fetal membranes of patients with preterm premature rupture of membrane (PPROM) and full-term premature rupture of ...

OBJECTIVE Iatrogenic preterm premature rupture of membranes (iPPROM), the main complication of invasive interventions in the prenatal period, seriously limits the benefit of diagnostic or surgical prenatal procedures. This study aimed to evaluate preventive plugging of punctured fetal membranes in an ex vivo situation using a new mussel-mimetic tissue adhesive (mussel glue) to inhibit leakage. ...

Preterm birth is defined as birth before the completion of 37 weeks of gestation. The frequency of preterm birth in the United States increased from 10.7% in 1992 to 12.3% in 2003. 1 Preterm births can be categorized as those undertaken because of a specific indication or as spontaneous preterm births. Indicated preterm births occur when a health care provider delivers a baby because of medical...

This paper describes Rapture | a system for revising probabilistic knowledge bases that combines connectionist and symbolic learning methods. Rapture uses a modi ed version of backpropagation to re ne the certainty factors of a probabilistic rule base and it uses ID3's information-gain heuristic to add new rules. Results on re ning three actual expert knowledge bases demonstrate that this combi...

This paper describes RAPTURE a system for revising probabilistic knowledge bases that combines neural and symbolic learning methods. RAPTURE uses a modified version of backpropagation to refine the certainty factors of a MYCIN-style rule base and uses ID3's information gain heuristic to add new rules. Results on refining two actual expert knowledge bases demonstrate that this combined approach ...
