in order to improve the level of intelligence, availability, being on demand, convenience, information and humanization of rural public transportation systems, they are more willing to use modern information and communicative technologies. in addition to management services, intelligent transportation systems can provide passengers, drivers, travel agencies and other institutions with other ser...

PURPOSE To develop three-surface paraxial schematic eyes with different ages and sexes based on data for 7- and 14-year-old Chinese children from the Anyang Childhood Eye Study. METHODS Six sets of paraxial schematic eyes, including 7-year-old eyes, 7-year-old male eyes, 7-year-old female eyes, 14-year-old eyes, 14-year-old male eyes, and 14-year-old female eyes, were developed. Both refracti...

Retained intraocular graphite foreign bodies are uncommon. Although they are generally inert, they have been reported to cause severe inflammatory reaction and progressive damage to intraocular structures. We report a case of a six-year-old girl with a retained intraocular graphite pencil lead foreign body in the anterior chamber of the eye and discuss the various considerations in the manageme...

background: although the depth of the counting chamber is an important factor influencing sperm counting, no research has yet been reported on the measurement and comparison of the depth of the chamber. we measured the exact depths of six kinds of sperm counting chambers and evaluated their accuracy. materials and methods: in this prospective study, the depths of six kinds of sperm counting cha...

The University of Denver's remote sensor (FEAT) was used for an on-road motor vehicle carbon monoxide (CO) and hydrocarbon (HC) emissions survey in Australia during April and May, 1992. Twelve locations in Melbourne area were selected as the survey sites. Most of these locations were the on or off ramp of a freeway or a two way road divided by a solid or painted traffic island. The raw data fro...

this paper modeled heating air of a room through examining free convection in a 3d chamber. the chamber had cold and hot sources with tc and th temperatures, respectively. its other walls were adiabatic. this study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. to conduct the st...

In this we analyze measures Bank Russia stabilize situation in financial market, supporting businesses: general supportive conclusions Chamber Commerce and Industry Federation, for public interest entities...

PURPOSE To compare ocular component growth curves among four refractive error groups in children. methods Cycloplegic refractive error was categorized into four groups: persistent emmetropia between -0.25 and +1.00 D (exclusive) in both the vertical and horizontal meridians on all study visits (n = 194); myopia of at least -0.75 D in both meridians on at least one visit (n = 247); persistent hy...

PURPOSE To investigate the contribution of the individual ocular components, i.e. anterior chamber depth, lens thickness and vitreous chamber depth, to total axial length in patients with esotropic amblyopia. METHODS The study population consisted of 74 children, aged between 5 and 8 years: thirty-seven patients with esotropic amblyopia and 37 healthy volunteers (control group). The participa...

Myopia, or nearsightedness, is a worldwide common type of refractive error. It is a non-life-threatening disorder with huge social and economic consequences due to its increasing prevalence. Axial length (AL) is the primary determinant of non-syndromic myopia. It is a parameter representing the combination of anterior chamber depth, lens thickness and vitreous chamber depth of the eye. AL can a...
