BACKGROUND The two-incision technique and the modified Watson-Jones technique use muscular intervals and avoid muscle cutting in total hip arthroplasty (THA). However these two techniques have not been compared. METHODS A prospective randomized study of clinical outcomes and patient preferences was performed in 20 patients who had a two-incision THA in one hip and a modified Watson-Jones THA ...

BACKGROUND Few studies have provided evidence to verify that bottle-feeding has negative effects on breastfeeding. There is insufficient evidence to support the practice of cup-feeding to supplement breastfeeding. However, it has been applied as a substitute for bottle-feeding to promote breastfeeding. The aims of this study were to explore the differences in infant sucking competence, infant s...

purpose : to investigate the impact of socioeconomic factors on presenting severity of glaucoma methods : in a cross-sectional study at farabi eye hospital, and during 12 months study period, 258 patients with newly diagnosed glaucoma were enrolled and socioeconomic status of the patients were evaluated. results : lower socioeconomic score was associated with higher intraocular pressure (r=-0.3...

surface roughness is a significant parameter which determines the efficiency of optical components. surface damages induced by grinding strongly influence the mechanical strength and optical quality of optical glasses. it is meaningful to rapid evaluate the surface roughness through the measurement of different grinding parameters. in this study, a cup diamond wheel (d64) is used in grinding pr...

Abstract In the present research, the behavior of 304L austenitic stainless steel in the deep drawing process has been studied at the room temperature through experimental and finite element simulation method. Magnetic method calibrated by XRD was used to measure induced-martensite. Martensite volume fraction in the various portion of the deep drawn cup under optimum Blank Holder Force (BHF) a...

peltier technology opens new opportunities for specialapplications. in the current project, this technology was appliedto design and fabricate a portable thermoelectric beveragecooler and thermoelectric cup. the simulation and results of theexperiment showed that the common beverage cooler is not asuitable design for ignoring the effect of natural convection incooling. in our thermoelectric cup...

PURPOSE To use novel confocal scanning ophthalmoscopy technology to test hypothesis that HIV-seropositive patients without history of retinitis with a history of a low CD4 count are more likely to have damage to their retinal nerve fiber layer (RNFL) when compared to patients with high CD4 count. In addition, we compared optic disc morphologic changes with glaucoma. DESIGN Cross-sectional stu...

OBJECTIVES To examine the quality and cost of lunches brought from home by elementary and intermediate school students. DESIGN, SETTING, AND PARTICIPANTS An observational study was conducted in 12 schools (8 elementary and 4 intermediate) in one Ho...

In this paper, we present the Smart Dice Cup, a novel interaction device aimed at gaming applications in smart home environments. The Smart Dice Cup is used in a similar way as a traditional leather dice cup to generate random numbers. Integrated accelerometers relate the shaking of the device to the resulting rolls of the dice. In addition to an autonomous stand-alone mode, where the Smart Dic...
