X-ray diffraction was utilized to follow the transformation from β-SiC (3C) to the various α-SiC polytypes in the presence of AlN and Al2O3 additives after hot pressing from 1700 to 2100 ◦C. The 2Hand 6H-polytypes of α-SiC were the predominate polytypes with additions of only AlN or Al2O3, respectively. The amount of 2Hand 6H-polytypes, and subsequently the microstructural morphology of the SiC...

Carin-ALN is an interesting new rule learning bias for ILP. By allowing description logic terms as predicates of literals in datalog rules, it extends the normal bias used in ILP as it allows the use of all quantified variables in the body of a clause. It also has at-least and at-most restrictions to access the amount of indeterminism of relations. From a complexity point of view Carin-ALN allo...

Background and objectives Few studies have evaluated the effect of the topical application of sodium alendronate (ALN) on the treatment of intrabuccal bone defects, especially those caused by periodontitis. This 6-month randomized placebo controlled clinical trial aimed at evaluating the effect of non-surgical periodontal treatment associated with the use of 1% ALN, through clinical evaluations...

AlN thin film was prepared over different metal substrates using DC sputtering at various sputtering parameters. The XRD spectra revealed the presence of mixed (cubic and hexagonal) phases for all samples other than samples prepared at 300W with Ar:N2 gas ratio of 14:6. The intensities of cubic phases observed at copper (Cu) substrates increased drastically with high sputtering power and N2 gas...

Learning in an ALN mode is modeled by a set of educational processes. The group is modeled by an abstract entity that provides services to the learners via its group educational processes. The learners reciprocate by their corresponding educational processes. Following findings of the Social Interdependence Theory of Cooperative Learning, we conjecture that the ALN is Cooperative Learning enhan...

PURPOSE The purposes our study was to find out any histologic factors associated with negative conversion of axillary lymph node (ALN) after neoadjuvant chemotherapy (NAC). We also evaluated the association between the decrease in size of primary breast tumor and negative conversion of ALN. METHODS From January 2012 to November 2014, we included 133 breast cancer patients who underwent NAC an...

CONTEXT Information on the use of oral bisphosphonate agents to treat pediatric osteogenesis imperfecta (OI) is limited. OBJECTIVE The objective of the investigation was to study the efficacy and safety of daily oral alendronate (ALN) in children with OI. DESIGN AND PARTICIPANTS We conducted a multicenter, double-blind, randomized, placebo-controlled study. One hundred thirty-nine children ...

This analysis of research literature seeks to gain insight into the study of the effectiveness of Asynchronous Learning Networks (ALN). A database of material gathered from the papers reporting the studies is described. The current picture of that data is highlighted and discussed. A framework of three sets of factors related to ALN effectiveness is described. Within this framework an analysis ...

The synthesis of AlN and TiB2 by spark plasma sintering (SPS) and the effect of Nb2O5, Y2O3 and ZrO2 additions on the mechanical properties and densification of the produced composites is reported and discussed. After the SPS process, dense AlN and TiB2 composites with Nb2O5, Y2O3 and ZrO2 were successfully prepared. X-ray diffraction analysis showed that in the AlN composites, the addition of ...
