The CFD simulation of heat transfer characteristics of a nanofluid ina circular tube under convective heat transferwas considered using the fluentsoftware (version 6.3.26) in the laminar flow. Al2O3nano- particles in water with concentrations of 0.5, 1.0, 1.5, 2 and 2.5% were studied in the simulation. All thermo-physical properties of nanofluids were temperature independent. It was concluded t...

Names as markers of identity are a source of a wide variety of information. This paper explores the names of characters to show the sociocultural factors which influence the choice of names and the effects that the names of these characters have on the roles they play. Using a variety of personal names from Ayi Kwei Armah’s Fragments, Buchi Emecheta’s The Joys of Motherhood, a...

background: corneal collagen cross-linking with riboflavin, also known as collagen cross-linking (cxl), involves the application of riboflavin solution to the eye that is activated by illumination with ultraviolet a (uva) light. we survey here the topographic corneal changes one year after cxl in patients with corneal keratoconus. materials and methods: this prospective randomized clinical tria...

conclusions within the limitations of this study, disinfectants were able to completely eliminate microorganisms carried by the alginate impressions. however, more efficient disinfection methods are needed to eliminate the risk of cross contamination by condensational silicone impressions. background dental impressions often carry microorganisms that may cause cross-infection from patients to d...

children need to learn to use the roads safety. road safety is essential for children’s freedom, development and exercise. when walking near a road it is a good idea to: 1. hold your child's hand. 2. don't let them run ahead. 3. look out for and encourage your child to be aware of hidden entrances or driveways crossing the pavement. 4. put reins on a younger child if they're not ...

purpose: to compare the efficacy and safety of xalatan(r) with generic latanoprost (xalabiost) in glaucoma. methods: in this randomized crossover study, 17 patients with primary open angle glaucoma or ocular hypertension were randomized into 2 groups. group a received xalatan for 6 weeks followed by xalabiost for 10 weeks. group b received xalabiost for 6 weeks which was then crossed over to xa...
