Statistička analiza rezultata ispitivanja fizičko-mehaničkih svojstava kontrolnih betonskih kocki

Cilj ovog istraživanja je prikupljanje, obrada i statistička analiza rezultata ispitivanja uzoraka betonskih kocki koji su ispitani u Laboratoriji za materijale Građevinskog fakulteta u Beogradu prema standardu SRPS ISO 4012:2000 u periodu od 2012. do 2017. godine. Za potrebe analize, preuzeti su podaci iz Izveštaja o ispitivanju kontrolnih betonskih kocki, prepoznate su i klasifikovane osnovne karakteristike očvrslog betona. Izvršena je statistička analiza datuma betoniranja, starosti uzoraka, sastava betona, zapreminske mase, čvrstoće pri pritisku, zahtevane marke betona itd. Statistika je pokazala da su najčešće upotrebljavani cementi sledećih oznaka: CEM II A-M (V-L), CEM II A-M (S-L), CEM II A-S, a da najveće učešće imaju marke betona MB 30 sa 66,8% i MB 40 sa 14,3% udela

Quality of life and dermatovenerology

Quality of life (QoL) is used in the natural and social sciences as a relatively new category which deserves more attention in research. Quality of life related to health is a term commonly used when QoL on health. An increasing number of research studies that are based on an examination of the QoL. This paper analyzes the concept of the QoL, the possibilities of measuring the QoL, a special emphasis is placed on measuring QoL in dermatovenereology. Given that the skin disease are of particular significance for the patient, the said indices are dermatologically quality of life, especially the quality of life of patients dermatological (DLQI)

Smart DFT Based PMU Prototype

This paper presents recent innovation in the field of the Synchronized Measurement Technology. An advanced, low complexity algorithm for synchrophasor estimation and the processing platform running embedded Linux are used to develop a cost-efficient Phasor Measurement Unit (PMU) prototype. The Smart Discrete Fourier Transform (SDFT) is adapted for the purpose of synchrophasor estimation, being implemented by using Python programming language. The developed prototype sends synchro-measurements according to the IEEE Standard C37.118 specifications. The prototype performance characteristics are evaluated by using RTDS power system simulator as hardware-in-the-loop. The obtained results suggest further algorithm improvements to fully comply with the IEEE Standard C37.118.1a-2014 specified requirements. The developed prototype offers an affordable PMU solution for improving the grid observability.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Intelligent Electrical Power Grid

Difference in influence of commercial industrial paints on microbial biofilms and planktonic cells

This study compares the effect of commercial industrial paints on the Escherichia coli PMFKG-F2, Proteus mirabilis PMFKG-F4 and Saccharomyces cerevisiae PMFKG-F6 planktonic cells and biofilms. A MBECTM-HTP assay and standard 96 microtiter plate assay were used to test the levels of resistance of planktonic cells and biofilms. The minimum inhibitory concentration (MIC) and minimum lethal concentration (MLC) of the tested substances, which affects planktonic cells and biofilms, were determined and the results were confirmed by fluorescence microscopy. Results obtained for planktonic cells were compared between them and with the results obtained for biofilms. Noticeable difference in the resistance between the biofilms and the planktonic cells on paints, was observed. The E. coli PMFKG-F2 planktonic cells showed the highest resistance in the presence of the tested substance 2 (MICp 2.5 μl/ml), while the P. mirabilis PMFKG-F4 planktonic cells showed the highest resistance in the presence of the tested substance 2 (MICp 5 μl/ml). The S. cerevisiae PMFKG-F6 planktonic cells showed the same level of resistance in the presence of the tested substances 1, 2 and 5 (MICp 0.62 μl/ml). The E. coli PMFKG-F2, P. mirabilis PMFKGF4 and S. cerevisiae PMFKG-6 biofilms showed the highest resistance in the presence of the tested substance 5 (MICb 125 μl/ml, MICb 125 μl/ml and MICb 62.5 μl/ml). The obtained results suggest that the biofilm may have a potential to be used in bioremediation of wastewater contaminated with industrial paints

The efficacy of moxifloxacin in patients with bacterial keratitis

Background/Aim. Keratitis is a sociomedical problem of moderately developed countries. including Serbia, too. The incidence of bacterial keratitis in the world is about 20% in relation to all keratitis, but its frequency in Serbia is still not known. Bearing in mind the complications in the front segment of the eye after bacterial keratitis (ulcer, neovascularization, fibrosis) and decline in visual acuity, it was necessary to assess the efficacy of local therapy by moxifloxacin which will shorten the healing time and reduce complications. The aim of the study was to analyze the efficiency of shortening the treatment of bacterial keratitis with moxifloxacin. Methods. The study was designed as prospective, randomized, double-blind study. The study included 30 patients with diagnosed keratitis and locally applied antibiotic moxifloxacin, and 60 patients in a control group, with locally applied artificial tears. All participants were subjected to complete clinical ophthalmologic analysis (2015/16), for a period of 1–15 days after the application of therapies (healing time of corneal pathology). The following was determined in all patients: degree of hyperemia, degree of epithelial defect, level of corneal sensitivity, level of tear secretion and tear quality, degree of conjunctival secretion, degree of neovascularisation and corneal scarring, degree of visual acuity, score of subjective symptomatology and correlation of ophthalmological findings and subjective symptoms. Results. There was a statistically significant difference in times of therapeutic efficacy/clinical response between the study group patients who received moxifloxacin and the control group patients who received arteficial tears. Conclusion. Local application of moxifloxacin had therapeutic effect (total benefit) both in terms of the effective shortening of the healing time and also the reduction of the complications of bacterial keratitis, without unwanted effects

The influence of sociodemographic factors on the use of antihypertensive drugs among adults in Serbia: Cross-sectional study

Background: Despite the knowledge that they have high blood pressure, which can be controlled with medicines, one portion of the patients still ignores doctor's advice. The aim of the research was to examine the impact of socio-demographic factors for treatment of hypertension among adults in Serbia. Subjects and methods: In the study, we used data from the National Health Survey of the Republic of Serbia in 2013. The sample consisted of respondents who had diagnosed hypertension, 5073 of them. The dependent variable in the study was binary (treatment, or no treatment of hypertension) and independent was socio-demographic characteristics of respondents. Logistic regression was used to determine sociodemographic predictors associated with blood pressure control. Results: From a total of 5073 diagnosed hypertensive patients, 91.3% of them cures high blood pressure. Women, older, medium rich patients, those who follow health topics on television and those who do not follow them on the Internet, who, in the past year, have been hospitalized or used the services of daily care significantly more often treat hypertension. The results of binary logistic regression in which the dependent variable is the treatment of high blood pressure, showed that a statistically significantly predictors are: age, gender, the wealth index and monitoring topics related to health through television and the Internet. In the treatment of hypertension, the strongest predictor was the index of well-being. Thus, people who are medium rich are almost three times more likely to treat high blood pressure compared to the richest (OR=2.94, 95%CI=1.54-5.59). A statistically significant difference in treatment is not recorded between the richest and the poorest (p> 0.05). Men are 1.5 times more likely to treat their tension as compared to women (OR=1.54, 95%CI=1.02-2.32). People following itopics related to the health via the internet are1.7 times more likely to treat hypertension in comparison to subjects who do not follow these topics via the Internet (OR=1.72, 95%CI=1.07-2.76). Conclusion: Analysis of the impact of sociodemographic characteristics on the awareness of patients about the importance of treatment of hypertension is an important step in defining the strategies for treatment of patients
