    Opis:
    Introduction and objective. There is a significantly higher risk of lipid disorders occurrence, including atherogenic dyslipidemia in women after menopause than it is in general population. The aim of the work was to investigate the correlation between health behaviours and the occurrence of lipid disorders in women after menopause working in agriculture. Material and methods. The study was conducted in years 2015–2016 and included 843 post-menopausal women working in agriculture. The following were used: a questionnaire including socio-demographic data, laboratory lipid tests, inventory of health behaviours. The following were estimated: logistic regression models for serum lipids concentration versus frequency of health behaviours in the examined women. Results. Adverse lipid profile was found in over a half of post-menopausal women working in agriculture, whereas the frequency of health behaviours were estimated at the average level, although the frequency of correct eating habits and health practices was significantly lower than preventive behaviours and positive psychological attitudes. A correlation was found between the frequency of health behaviours and the occurrence of lipid disorders in women after menopause working in agriculture: more frequent health practices co-existed with the lower concentration of total cholesterol and a higher concentration of HDL-cholesterol, more frequent preventive behaviours co-existed with lower concentration of LDL-cholesterol. Women with higher concentration of triglycerides undertook pro-health practices relatively more often. Conclusions. The study revealed a high prevalence of lipid disorders in postmenopausal women working in agriculture. More effective health education programmes are necessary in the area of reduction the risk factors of CVD in the population of women working in agriculture.

    Opis:
    Introduction and objective. Stress at the work place reduces efficiency, as well as increasing accidents and absences, which may cause various diseases, including cardiovascular diseases. The aim of the study is an analysis of the prevalence and causes of stress in intellectual work, and its correlation with the prevalence of cardiovascular diseases in women at non-mobility working age. Materials and method. The study was conducted in 2016–2017 in a group of 300 women aged 45–60 in non-manual employment. A questionnaire for subjective job evaluation was used. Logistic regression models for the occurrence of CVDs versus frequency of occurrence of individual causes of work stress among the respondents were estimated. Results. Women at non-mobility working age with non-manual employment are especially exposed to stress, half of them experience high level of stress at work, most often caused by social contacts and lack of rewards and support. Cardiovascular diseases were found in 26.5% of the women studied who were also significantly higher exposed to the occurrence of health hazards due to exposure to harmful factors, or due to an accident at work, changes in the workplace, the need to compete with others,and the need to perform the task despite the lack of appropriate material resources, compared with women without such diseases. Conclusions. The study revealed a high prevalence of occupational stress in non-manual employment, indicated its main causes that correlated with the alence of cardiovascular diseases. Actions are needed to reduce the level of stress in the work of women at non-mobility working age, to maintain their work ability and quality of life.

    Opis:
    Introduction. Cessation of tobacco use has the potential to provide the greatest immediate benefits for tobacco control. Understanding the social determinants of smoking cessation is an essential requirement for increasing smoking cessation at the population level. The purpose of this study was to analyze the socio-economic dimensions associated with cessation success among adults in Argentina and Uruguay. Materials and methods. Data from the Global Adult Tobacco Survey (GATS), a cross-sectional, population-based, nationally representative survey conducted in Argentina (n=5,383) and Uruguay (n=4,833) was utilized. Univariable and multivariable logistic regression analyses with results being presented as odds ratios (OR) with 95% confidence intervals were applied to study differences among those respondents who sustained smoking abstinence (≥1 year) and those who continued smoking. Results. The GATS study revealed that social gradients in tobacco quitting exist in Argentina and Uruguay. Being aged 25–34, particularly men in Uruguay, women in Argentina, low educated men in Argentina and having a lower asset index were associated with reduced odds for quitting. Conclusion. Factors that are driving differences in smoking cessation between diverse social groups in Latin America countries need to be considered when implementing relevant interventions to ensure tobacco control strategies work effectively for all population segments.

    Opis:
    Przedstawiono wyniki oznaczania zawartości miedzi w strumieniach technologicznych pochodzących z procesu otrzymywania poli(tlenku fenylenu) (PPO) metodą polimeryzacji strąceniowej 2,6-dimetylofenolu z użyciem soli miedzi(II) jako kokatalizatora. Techniką FAAS (płomieniowa absorpcyjna spektrometria atomowa) badano mineralizaty próbek pochodzących z węzła odzysku rozpuszczalników (metanol lub etanol, toluen) i z węzła odzysku składników układu katalitycznego [jony miedzi(II), morfolina]. Zaproponowano procedurę analityczną obejmującą, na etapie przygotowania roztworów do badań, mineralizację próbek za pomocą nowoczesnego systemu do roztwarzania mikrofalowego Ultra WAVE (Milestone). Metoda ta (w połączeniu z techniką FAAS) pozwala na szybkie i sprawne oznaczanie zawartości miedzi w ciekłych próbkach z matrycą organiczną (metanol/etanol – toluen, morfolina) i wodno-organiczną.
    Results of copper determination in process streams coming from the poly(phenylene oxide) (PPO) production by precipitation polymerization of 2,6-dimethylphenol using the copper(II) salt as a co-catalyst have been presented. A microwave-assisted sample preparation analytical procedure for the determination of copper in stream samples from the organic solvents (methanol or ethanol, toluene) and the catalyst components [copper(II) ions, morpholine] recovery nodes using a modern Milestone Ultra WAVE digestion system combined with the FAAS technique has been proposed. The method is useful for quick and efficient determination of copper in liquid samples with organic (methanol/ethanol – toluene, morpholine) mixtures and aqueous-organic matrix.

    Opis:
    Prace badawcze dotyczyły otrzymywania i przetestowania katalizatorów do syntezy 2,6-dimetylofenolu, które mogłyby pracować jako złoże fluidalne. Zsyntezowano tlenek krzemu, na który nanoszono w różnych wariantach tlenki: żelaza(III), magnezu(II), chromu(III) i miedzi(II). Ponadto przebadano katalizator TZC-3/1 produkowany przez Grupę Azoty S.A. Tlenek krzemu z naniesionym na powierzchnię tlenkiem magnezu umożliwił prawie 100% przereagowanie fenolu w temp. 733K, przy selektywności w stosunku do 2,6-dimetylofenolu bliskiej 60%. Podobny stopień przereagowania fenolu otrzymano dla katalizatora przemysłowego TZC-3/1, ale jego selektywność względem 2,6-dimetylofenolu wynosi 90%. Wyniki eksperymentów wskazują, że najlepszym spośród badanych katalizatorów jest przemysłowy katalizator TZC-3/1 pozwalający otrzymać najlepsze wyniki w najniższej temperaturze.
    Research works were focused on obtaining and testing of catalysts for 2,6-dimethylphenol synthesis that could be used as fluidized bed. Silicon oxide was synthesized, on which subsequently various variants of iron (III), magnesium (II), chrome (III) and copper (II) oxides were deposited. Moreover, catalyst TZC-3/1 produced by Grupa Azoty SA was tested. Silicon oxide with deposited magnesium oxide allowed almost 100% conversion of phenol at 733K with selectivity towards 2,6-dimethylphenol equal to 60%. Similar degree of conversion for phenol was obtained for industrial catalyst TZC-3/1, but its selectivity towards 2,6-dimethylphenol was equal to 90%. Experimental results indicate that the best one among examined catalyst is the industrial catalyst TZC-3/1 that allows obtaining best results at lowest temperature.
