- چکیده:
- چکیده انگلیسی: In this study, Ni/NiO nanocomposites were prepared using simple, environment-friendly and low-cost solid-state thermal decomposition method from nickel (II) Schiff base complex at 400 and 500°C for 3 hours. The Ni/NiO nanocomposites were characterized with Fourier transformed infra-red spectroscopy (FT-IR), X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and X-Ray fluorescence (XRF). Results of XRD and XRF confirmed that the nanocomposite products contain a mixture of nickel and nickel oxide. The Ni or NiO content varied with the temperature used for the synthesis. Upon increasing the temperature from 400 to 500°C, the amount of NiO was found to be increased due to a complete oxidation of Ni to NiO. The TEM images demonstrated that the composites were spherical with a distribution size of about 10-30 nm. In addition, the products displayed reasonable electrochemical performance.

- چکیده:
- چکیده انگلیسی: Second homes tourism is one of the patterns of tourism expansion especially in rural and mountainous areas that is achieved through the expansion of the ownership of second homes (upcountry or holiday homes). Despite the relatively long history of second homes in rural areas, second home tourism has recently experienced a resurgence, often due to new patterns of production and economic consumption. The purpose of this study was to investigate the second homes in tourism in Damavand. The city has been attracted by tourists, especially homeowners, due to its specific geographical location, such as the countryside, beautiful highlands and valleys, lack of pollution in the cities, and its terms of its easy access to this city. Descriptive and analytical research method and processing of 127 questionnaires in SPSS environment showed that there is a significant relationship between second homes and tourism development.

- چکیده:
- چکیده انگلیسی: In recent years, Partially Encased Composite columns are evaluated as new achievements in the field This paper presents a combined experimental and theoretical study on the mechanical performances of six octagonal PEC columns subjected to axial compressive and bending moment loading. The main difference between them was the details of concrete strengthening. In the experimental study, the parameters investigated were the sort of detail of strengthening and the mode of failure. The results were represented as load-deformation and moment-rotation curves. The test results were compared with the measurements of relations captures from CSA S16-14 and EN 1994-1-1 codes. The comparison of the code equations given in CSA S16-14 and EN 1994-1-1 revealed that the equation in CSA S16-14 underestimates the capacity. Also, the failure mode was similar for all three concentrated tests: concrete cracking coupled with the steel flange buckling.

- چکیده:
- چکیده انگلیسی: Background and Objectives: Prostate cancer was reported to be the second cause of cancer death in men in 2013.
Studies have shown that those with higher knowledge levels are much more likely to undergo prostate cancer screening.
The present study was aimed to determinate the effect of an educational program for prostate cancer prevention on
knowledge and prostate-specific antigen (PSA) testing in men over 50 years old in community areas of Shiraz. Methods:
This clinical trial was conducted among 93 men over 50 years old who were randomly divided into an intervention
(n=48) and a control (n=45) group. The intervention group took part in an educational program focusing on the
importance of prostate cancer prevention with emphasis on cultural and economic issues. Data were collected using
a demographic information form, the Weinrich questionnaire for measuring the knowledge level about prostate cancer
and screening, and also a researcher-made questionnaire covering reasons for not doing the test, before and 3 months
after the intervention. Additionally, participation in PSA testing was evaluated 3 months after the intervention. All data
were entered into the SPSS statistical software (version 14) and pFindings: The results showed that the intervention group’s participation in PSA testing increased from 6.12% to 36.4%
three months after the intervention. However, no significant change was observed in the control group. In addition,
the intervention group’s mean score of knowledge increased by about 2.69 points after the intervention, and a significant
difference was observed between the two groups in this regard (p<0.05). Conclusion: The results of the current study
revealed effectiveness of the educational program in increasing the knowledge about prostate cancer and participation
in PSA testing in men over 50 years of age. Hence, managers and authorities should execute plans to educate men
regarding prostate cancer screening and promote their health status.- انتشار مقاله: 06-05-1396
