DETERMINATION OF MICROSCOPIC OBJECTS DIMENSIONS USING DIGITAL IMAGES

The proposed method is less time consuming, since the microscope is needed only for obtaining the image of the measured object, as established of the object-micrometer or images of the Goryaev camera grid. Working with a scale ruler and an image is more comfortable and less difficult than working with a microscope, an ocular micrometer and a coordinate microscope table. Working with an image, unlike working with a microscope, is convenient for people using glasses as it reduces the burden on the researcher’s vision.</p

Co-consumption of vegetables and fruit, whole grains, and fiber reduces the cancer risk of red and processed meat in a large prospective cohort of adults from Alberta’s tomorrow project

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. We examined whether co-consumption of red and processed meat with key foods items and food constituents recommended for cancer prevention (vegetables and fruit, whole grains, and fiber) mitigates cancer incidence. In a prospective cohort of 26,218 adults aged 35–69 years at baseline, dietary intake was collected through 124-item past-year food frequency questionnaire. Incidence of all-cause and 15 cancers previously linked to red and processed meat intake was obtained through data linkage with a cancer registry (average follow-up 13.5 years). Competing risk Cox Proportional Hazard models estimated cancer risk and Accelerated Failure Time models estimated time-to-cancer occurrence for different combinations of intake levels while considering mortality from vital statistics and established confounders. Co-consumption of low vegetables and fruit intake with high processed meat was associated with higher incidence of all-cause and 15 cancers (men: HR = 1.85, 1.91; women: HR = 1.44, 1.49) and accelerated time-to-cancer occurrence (men: 6.5 and 7.1 years and women: 5.6 and 6.3 years, respectively), compared to high vegetables and fruit with low processed meat intake. Less pronounced and less consistent associations were observed for whole grains and fiber and for red meat. The findings provide initial evidence toward refining existing cancer prevention recommendations to optimize the intake and combination of foods in the general adult population

Exploring educational inequalities in hypertension control, salt knowledge and awareness, and patient advice : insights from the WHO STEPS surveys of adults from nine Eastern European and Central Asian countries

Objective: To inform strategies aimed at improving blood pressure (BP) control and reducing salt intake, we assessed educational inequalities in high blood pressure (HBP) awareness, treatment and control; physician’s advice on salt reduction; and salt knowledge, perceptions and consumption behaviours in Eastern Europe and Central Asia. Design: Data were collected in cross-sectional, population-based nationally representative surveys, using a multi-stage clustered sampling design. Five HBP awareness, treatment and control categories were created from measured BP and hypertension medication use. Education and other variables were self-reported. Weighted multinomial mixed-effects regression models, adjusted for confounders, were used to assess differences across education categories. Settings: Nine Eastern European and Central Asian countries (Armenia, Azerbaijan, Belarus, Georgia, Kyrgyzstan, Republic of Moldova, Tajikistan, Turkey and Uzbekistan). Participants: Nationally representative samples of 30 455 adults aged 25–65 years. Results: HBP awareness, treatment and control varied substantially by education. The coverage of physician’s advice on salt was less frequent among participants with lower education, and those with untreated HBP or unaware of their HBP. The education gradient was evident in salt knowledge and perceptions of salt intake but not in salt consumption behaviours. Improved salt knowledge and perceptions were more prevalent among participants who received physician’s advice on salt reduction. Conclusions: There is a strong education gradient in HBP awareness, treatment and control as well as salt knowledge and perceived intake. Enhancements in public and patient knowledge and awareness of HBP and its risk factors targeting socio-economically disadvantaged groups are urgently needed to alleviate the growing HBP burden in low- and middle-income countries

Korekciniai veiksniai, į kuriuos atsižvelgiama nustatant žemės sklypų nuomos mokestį, kaip biudžeto užpildymo įrankį savivaldybėje (Čeliabinsko miesto pavyzdys)

There is a lack of common and clear methods for calculating correction factors in determining the amount of rent for use of land plots located in the territory of the municipality on state property, and the rate of rent is therefore not delimited. Land plots which are under municipal ownership objectively necessitate the perfection of a technique of defining rent for use of land plots, taking into account the interests of both the tenants and the municipality as lessor. This often comes at the expense of correction coefficients which, on the one hand, can lead to the deterioration of the investment climate in the municipality due to the overestimated value of the coefficients. On the other hand, they can lead to a significant decrease in budgetary revenues due to the underestimated value of these coefficients in lease of land plots.Nėra bendrų ir aiškių korekcinių koeficientų apskaičiavimo metodų, kuriais remiantis būtų galima nustatyti savivaldybės teritorijoje esančių žemės sklypų nuomos mokesčio dydį. Neatriboti valstybei ir savivaldybei priklausantys žemės sklypai sukelia objektyvią būtinybę tobulinti žemės sklypų nuomos mokesčių nustatymo būdus. Reikalinga atsižvelgti į tiek nuomininkų, tiek savivaldybės, kaip nuomotojo, interesus per korekcinius koeficientus, kurie pablogina investicinį klimatą savivaldybėje, iš vienos pusės, dėl pervertintos apskaičiuotų koeficientų vertės, antrą vertus, dėl reikšmingo biudžeto pajamų sumažėjimo dėl žemės sklypų nuomos

Exploring near-border territories of Russia: peculiarities of ethnic identity of population

This article describes the results of exploring ethnic identity of population, residing in border regions of Russia. As a method, a binary regression model was built to evaluate the probability of inclusion in the group with apparent ethnic identity, which had been measured by means of one statement from cognitive component. In result, the model has confirmed the close relationship between different parts and manifestations of the ethnic identity. As a conclusion, the boundary area needs special approach to the management in the interethnic sphere and diversification of national strategies, taking into account all facets of ethno-cultural lifeEste artículo describe los resultados de la exploración de la identidad étnica de la población, que reside en las regiones fronterizas de Rusia. Como método, se construyó un modelo de regresión binaria para evaluar la probabilidad de inclusión en el grupo con identidad étnica aparente, que se había medido por medio de una declaración del componente cognitivo. Como resultado, el modelo ha confirmado la estrecha relación entre diferentes partes y manifestaciones de la identidad étnica. Como conclusión, el área límite necesita un enfoque especial para la gestión en la esfera interétnica y la diversificación de las estrategias nacionales, teniendo en cuenta todas las facetas de la vida etnocultura

SEPARATION, CONCENTRATION AND DETERMINATION OF METAL IONS IN STREAM WITH USE OF NON-COVALENT IMMOBILIZED COMPLEXING REAGENTS

The multifunctional flow system with sorption column permitting to perform the photometric determinations of the metal ions with on-line concentration, simultaneous determination of two components and to eliminate the influence of the preventing ions has been developed. The microwave flow sample-preparation procedure of the natural waters has been developed. The capillary columns with hydrophobic internal surface modified non-adequately with the organic reagents for substitution of the traditional sorption microcolumns have been proposed. The methods for modification of the sorption columns and concentrating chucks and also the methods for flow concentration of the metals have been developed. The procedure for production of the indicator powders and methods for flow detection of the metals with visual indication (method of indicator tubes) have been proposed. The work results have been recommended to the application at analysis of the sewage, technological solutions, atmospheric precipitations and soil extraction and require the widened use.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
