Design of Wi-Fi-based new generation electricity meter for smart grids and smart building applications
No full textSmart meters are among the fundamental components of smart grids due to their features such as high-accuracy energy measurement, remote reading, and control. They are also utilized to reduce the rate of illegal electrical energy use in some distribution areas. This paper presents the development of a Wi-Fi smart meter and designing a smart plug-in device for customer-side energy management. In this way, a method that does not require additional infrastructure and extra investment for remotely reading the energy consumption in environments with common Wi-Fi networks, such as large shopping malls, business centers, community buildings, villa cities, and university campuses has been proposed. The Wi-Fi smart meter and smart energy metering module (SEMM) support various user-friendly applications in accordance with the infrastructure of the smart grid and smart building applications. The SEMM is capable of measuring, monitoring, and remotely managing each electrical device. Thanks to the developed mobile application, customers can monitor their Wi-Fi smart meter data and also the consumption of each electrical device through the SEMMs as well as remotely manage these devices. The application examples presented in this study are also aimed at increasing awareness of energy saving for customers
Endoscopic versus microscopic ossiculoplasty: Does the functional outcome vary according to the type of osciculoplasty?
No full textObjective: To compare functional outcome of microscopic and endoscopic approach regarding type of ossiculoplasty.Methods: In this retrospective study, cases who had undergone type-II and type-III tym-panoplasty between February 2007 to September 2019 were divided into two groups according to the type of approach as microscopic and endoscopic. In cases with type-II reconstruction; Partial Ossicular chain Replacement Prosthesis (PORP), incus interposition and bone cement were used in order of frequency. Whereas in cases with type-III reconstruction, only Total Ossicular chain Replacement Prosthesis (TORP) was used. The average Air Bone Gap (ABG) was deter-mined pre-and post-operatively for the calculation of Air Conductance Gain (ACG). The ACG, pre-and post-operative ABG values of each group were compared with regard to the type of ossiculoplasty.Results: A total of 79 cases consisting of 32 females and 47 males who had undergone type-II and type-III tympanoplasty were enrolled. No statistically significant difference between microscopic and endoscopic approach was found in terms of ACG (p = 0.42), pre-(p = 0.23) and postoperative ABG (p = 0.99). We did not find any significant difference in terms of ACG, pre-and postoperative ABG between two approaches for type-II and type-III reconstructions (p > 0.05).Conclusions: According to the current study, endoscopic approach in type-II and type-III reconstruction is at least reliable as microscopic approach regarding functional outcome. Since both techniques have similar functional results, other factors (anatomic characteristics, habitude of the surgeon and duration of the surgery) should be considered when choosing the technique. Level of evidence: In the current paper we present a retrospective comparative study of two different approaches of a particular type of otologic surgery. Level of evidence corresponds to level III
Mixed convection due to rotating cylinder in an internally heated and flexible walled cavity filled with SiO2-water nanofluids: Effect of nanoparticle shape
No full textIn this study, numerical investigation of mixed convection in a square cavity filled with SiO2 nanofluid and volumetric heat generation is performed under the effect of an inner rotating cylinder and a flexible side wall. The top wall of the cavity is kept at constant cold temperature while the bottom wall is at hot temperature and the other walls of the cavity and the cylinder surface are assumed to be adiabatic. The finite element method is utilized to solve the governing equations. The Arbitrary Lagrangian-Eulerian method is used to describe the fluid motion with the flexible wall of the cavity in the fluid-structure interaction model. The effects of external Rayleigh number (between 10(3) and 5 x 10(6)), internal Rayleigh number (between 10(4) and 10(6)), Young's modulus of the flexible wall (between 5 x 10(2) and 10(6)), angular rotational speed of the cylinder (between - 2000 and 2000) and nano particle volume fraction (between 0 and 0.03) on the fluid flow and heat transfer are numerically studied for different solid nanoparticle shapes (spherical, cylindrical, brick and blade). It is observed that as the value of external Rayleigh number increases, internal Rayleigh number and elastic modulus of the flexible wall decrease, the local and averaged heat transfer enhances. The averaged heat transfer enhances with cylinder rotation in both directions for all nanoparticle types. Among all nanoparticle shapes, cylindrical ones show the best performance and spherical ones show the worst performance for heat transfer enhancement. (C) 2015 Elsevier Ltd. All rights reserved

Impact of telephonic interviews on persistence and daily adherence to insulin treatment in insulin-naive type 2 diabetes patients: dropout study
No full textObjective: The objective of this study is to evaluate the impact of sequential telephonic interviews on treatment persistence and daily adherence to insulin injections among insulin-naive type 2 diabetes patients initiated on different insulin regimens in a 3-month period. Methods: A total of 1,456 insulin-naive patients with type 2 diabetes (mean [standard deviation, SD] age: 56.0 [12.0] years, 49.1% were females) initiated on insulin therapy and consecutively randomized to sequential (n=733) and single (n=723) telephonic interview groups were included. Data on insulin treatment and self-reported blood glucose values were obtained via telephone interview. Logistic regression analysis was performed for factors predicting increased likelihood of persistence and skipping an injection. Results: Overall, 76.8% patients (83.2% in sequential vs 70.3% in single interview group, (P<0.001) remained on insulin treatment at the third month. Significantly higher rate for skipping doses was noted in basal bolus than in other regimens (27.0% vs 15.0% for premixed and 15.8% basal insulin, respectively, P<0.0001). Logistic regression analysis revealed sequential telephonic interview (odds ratio [OR], 1.531; 95% confidence interval [CI], 1.093-2.143; P=0.013), higher hemoglobin A1c levels (OR, 1.090; 95% CI, 0.999-1.189; P=0.049), and less negative appraisal of insulin therapy as significant predictors of higher persistence. Basal bolus regimen (OR, 1.583; 95% CI, 1.011-2.479; P=0.045) and higher hemoglobin A1c levels (OR, 1.114; 95% CI, 1.028-1.207; P=0.008) were the significant predictors of increased likelihood of skipping an injection. Conclusion: Our findings revealed positive influence of sequential telephonic interview, although including no intervention in treatment, on achieving better treatment persistence in type 2 diabetes patients initiating insulin
Vat Practices And Efficiency Analysis in Turkish Taxation System
No full textIndirect taxes, particularly in developing countries, have been deemed as essential for the finance of development. However, it has been widely known reality that this creates shrinking effect on the private sector savings. On the other hand, the efficiency and productivity of tax revenue are also important issues as well as taxation. Taxes such as Value Added Tax (VAT) and Private Consumption Tax (PCT) have been deemed as primary tools for modern taxation. In this study, we investigate the situation of tax revenues before and after 1985 in which VAT law was eacted. The further legal amendments across the years which have been made in order to improve the efficiency of VAT, have been evaluated together with relevant data
Adaptation and validation of the Turkish version of the Caring Culture Survey
No full textAim To assess the validity and reliability of the Caring Culture Survey in a sample of Turkish nurses. Background Health care institutions have increased their focus on the caring culture to improve the satisfaction of both employees and patients. However, there is a lack of valid and reliable tools in Turkish that measure nurses' perceptions of caring culture. Method This two-phase psychometric study was conducted by recruiting 240 nurses from one university hospital between August and October 2019. In phase 1, the scale's adaptation was implemented. In phase 2, construct validity was determined by confirmatory factor analysis. Reliability was tested by internal consistency and item-total correlation coefficients. Results Adaptation results showed that the Turkish version of the scale is adequate for linguistic and content validation. Confirmatory factor analysis indicated a significantly good fit for a three-factor model. Cronbach's alpha coefficient was 0.84 for the overall scale. Conclusion The Turkish version of the Caring Culture Survey showed consistently acceptable psychometric properties of reliability and validity. Implications for Nursing Management The Turkish version of the Caring Culture Survey can be used as an instrument to assess nurses' perceptions of caring culture by health care and nurse managers
