This study investigated the impacts of oral health-related quality of life (OHRQoL) on daily activities and work productivity in adults. A cross-sectional study was conducted in a supermarket chain in the state of São Paulo, which included 386 workers, age-range 20 - 64 years. Participants were examined for oral disease following WHO recommendations, and the oral health impact profile (OHIP) as...

Objective: The present study aimed to investigate the impact of the oral health status on the quality of life of groups of elderly adults in urban and rural regions of Greece with different educational backgrounds. Background: Health-Related Quality of Life (HRQoL) is significantly affected by an individual’s oral health status. Methods: A total of 501 elderly Greeks, 65–74 years (mean 71±5), w...

Precision forging process is widely used for the production of spur gears due to its advantages such as improved strength and surface finish, little waste of materials and reduction in the machining time of the gear. An important aspect of precision forging process is the load required to perform the process successfully and design the forging tools. In this research, a new kinematically admiss...

BACKGROUND To evaluate oral health related quality of life (OHQoL) in edentulous patients treated with immediately loaded implants in the maxilla. METHODS Fifty-one edentulous patients in two centers received six maxillary implants each were loaded within 24 h with provisional restoration. Definitive restoration was delivered 20-24 weeks later. OHQoL was evaluated preoperatively with the Oral...

the shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. in reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a s-shape profile. the pr...

The batch-to-batch model-based iterative optimal control strategy for batch processes is realized based on multilayer recurrent fuzzy neural network (MRFNN) and chaotic search. MRFNNs are used to model batch processes. Modeling and optimization problems are mainly solved by chaotic search. Due to model-plant mismatches and disturbances, the calculated optimal control profile may not be optimal ...

in thermal cracking plants, it is desired to apply an optimal temperature profile along the reactor to minimize the operation cost. in this article a simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking pilot plant. the model is used to predict the steady state profiles of the gas temperature and product yields. using a dy...

In this paper, the Cramér Rao bound (CRB) for range estimate between two underwater nodes is calculated. The nodes are equipped with Conductivity-Temperature-Density (CTD) sensors to measure their depths, and the sound speed at different depths, and an acoustic modem to measure their mutual time of flight. The measurement noise is assumed to be Gaussian distributed. We show how much the CRB get...

In arid and semi-arid regions, soil surface warming is a considerable phenomenon causing a high thermal gradient which makes water flow intensely. The degree of soil temperature is effective on crop production, plant growth and soil microorganisms. In recent years, the ascending trend of temperature has been substantially noticed by researchers in the issues of pointwise climate change and at w...

Measurements of the Hubble constant to distant galaxy clusters using the Sunyaev-Zeldovich effect are systematically low in comparison to values obtained by other means. These measurements usually assume a spherical isothermal β model for the intracluster medium (ICM). Formation processes and recent mergers guarantee that real clusters are neither spherical nor isothermal. We present the result...
