the paper describes an investigation about the application of the new multiple-impedance discontinuities model for optimizing profile diffuser barriers. the new multiple-impedance discontinuities model is much faster than the numerical method, thus it is used in an optimization process. the a-weighted insertion loss was used for the traffic noise spectrum. the result of optimization, which is d...

the current study aims to identify the effective factors and barriers to loyalty in electronic banking services in the private banks customers. for this purpose, a survey was done with a questionnaire sampling from 420 customers of private banks in golestan province, who have used electronic banking services in 2011. the results indicated that seven factors including preference, customer satisf...

Palliative care is a series of actions aiming to offer support to parents and their infants in order to improve their quality of life. Despite optimal outcomes, the provision of palliative care for infants and achieving these outcomes may be hardly feasible. The present study aimed to investigate the barriers to palliative care and gain insight into the solutions. Accordingly, the obstacles wer...

Effects of d-doping on barriers effective heights and series resistance of highly doped n-type GaAs/AIAs/GaAs/AlAs/GaAs heterostructures, grown by molecular beam epitaxy (MBE) at 400?°C, have been studied. As it was expected, inclusion of an n+ d-doped layer at each hetero-interface has reduced the barriers heights and series resistance of the structure significantly, while p+ d-doped layers ha...

conclusions results showed that whereas knowledge by itself cannot guarantee men’s participation in prostate cancer screenings, perceived barriers can play an important role in discouraging men from cancer screening participation. therefore, designing programs to address these barriers is very important. results the most common barriers to screening for prostate cancer were a lack of knowledge ...

A key feature of recent work on barriers to technology adoption is the assumption that monopoly rights of insiders are limited by the ability of industry outsiders to enter. This paper endogenizes the decision of a government to provide barriers to technology adoption alone or in combination with barriers to entry of outsiders. Using a political economy model, we find that a government provides...

background: metabolic syndrome (ms) is defined as a pattern of metabolic disorders including central obesity, insulin resistance or hyperglycemia, high blood pressure, and dyslipidemia. many studies show a clear relationship between diet and components of ms. the aim of the current study was to identify barriers to adherence to dietary recommendations among iranian ms patients. methods: the the...

objectives: the purpose of this study was to determine barriers and motivators of physical activity in older adults. methods & materials: in this cross sectional study 153 older adults were participated through classified randomized clustering method. the questionnaires were completed in face to face interview. descriptive statistics and u mann whitney test were used to analyzing data. results:...

today, all over the word, we see the scientists, thinkers, politicians, consumers, producers and ecologists (who support the environment) pretest against the method of agriculture, because trying to increase the crop outcome to its maximum rate for hectare through the irregular use of chemical input in industrial agriculture lead to a disaster in human life which will endanger the whole life on...

there have been increasing interests in finding new and innovative solution for removal of contaminants from soils recently. in the present investigation, electro kinetic (ek) process coupled with activated carbon barrier to remove nickel from kaolinite clayey soil is investigated. laboratory tests were performed by applying a constant voltage to nominal electric field strength of 1 and 1.25 v/...
