background: the aim of this study was to evaluate the results of amblyopia screening in ardabil province in three examination levels by kindergarten teacher, optometrist, and ophthalmologist. methods: in a cross‑sectional study, the results of the national amblyopic prevention program in 2–6 years old children in ardabil province were investigated in 2012. the results pertained to the examinati...
در این پایان نامه از نانولوله های کربنی به عنوان کاتد سرد در ساخت حسگر فشار گاز استفاده شده است. نانولوله ها به صورت عمودی به روش رسوب گذاری بخار شیمیایی-پلاسمایی روی زیر لایه سیلیکانی ریزماشینکاری شده رشد داده شده اند. رشد نانولوله ها در الگوهای ریزماشینکاری شده با استفاده از دستگاه sem بررسی شده است و تأثیر شرایط فرآیند رشد بر کیفیت لایه نانولوله ها بررسی شده است. حسگر فشار از غشاء سیلیکانی ا...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
background: screening mammography is an established intervention that leads to early breast cancer detection and reduced mortality. the lebanese ministry of health has initiated yearly awareness campaigns and provided free mammography in multiple centers around the country. methods: the study took place in two major areas of lebanon - beirut and south lebanon. this cross-sectional survey aimed ...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
A model and analytical method for solving a problem of coupled fluid flow in the reservoir/well system is presented. The 3-D drainage area is composed of three connected media: the tubing, the annuli (considered as a super conducting collector), and the reservoir itself. To couple the fluid flows in these areas a non-overlapping Dirichlet-Neumann domain decomposition method is developed theoret...
We evaluated antimicrobial exposure, discharge diagnoses, or both to identify surgical site infections (SSI). This retrospective cohort study in 13 hospitals involved weighted, random samples of records from 8,739 coronary artery bypass graft (CABG) procedures, 7,399 cesarean deliveries, and 6,175 breast procedures. We compared routine surveillance to detection through inpatient antimicrobial e...
