Analysis of Acoustic Absorption Coefficients and Characterization of Epoxy Adhesive Compositions Based on the Reaction Product of Bisphenol A with Epichlorohydrin Modified with Fillers.

Material development in acoustic engineering plays a significant role in various applications, such as industrial noise control. It is important and relevant to consider alternative materials capable of reducing noise levels in different frequency ranges. One commonly used material in engineering structures is epoxy adhesive compositions.

The Effect of Artificial Ageing on the Changes in Selected Properties of Organic Coated Sheets.

This contribution presents the results of research focused on changes in selected properties of organic-coated steel sheets in a corrosive environment of salt mist. The aim of this study was to characterise coated sheets and to analyse the influence of elevated temperature on changes in their selected properties. The methodology and experiments were chosen to simulate the accelerated ageing and to evaluate the surface of organic-coated steel sheets.

A Case Study of Ergonomic Risk Assessment in Slovakia with Respect to EU Standard.

Attention on work-related musculoskeletal disorders (WMSDs) involves statistical surveys showing an increasing trend in the incidence of WMSDs. Technological development has led to new tools and methods for the assessment of physical load at work. These methods are mostly based on the direct sensing of appropriate parameters, which allows more precise quantification.

New Findings in the Field of Thermal Drilling of Aluminum Alloys.

This paper explores the joining of materials by a new progressive method of thermal drilling. Many types of joints are utilized in industrial production, especially in the automotive industry, which requires the joining of different types of materials with different thicknesses. For these needs, it will be appropriate to apply the joining method of thermal drilling technology.

Community response to environmental noise and the impact on cardiovascular risk score.

Objective: The objective of our study was to investigate and evaluate the relationship between road traffic noise and cardiovascular risk.

Methods: The study sample (n=659; 36.9% male, 63.

Household exposure to secondhand smoke is associated with decreased physical and mental health of mothers in the USA.

Secondhand smoke is one of the most common toxic environmental exposures to children, and maternal health problems also have substantial negative effects on children. We are unaware of any studies examining the association of living with smokers and maternal health. To investigate whether non-smoking mothers who live with smokers have worse physical and mental health than non-smoking mothers who live in homes without smokers.

Positive and negative trends in university students' food intake.

In the time period 1992-2004 the food intake data (24 hour recall, frequency questionnaire) in 3 417 students of Medical Faculty Comenius University in Bratislava (1257 men and 2160 women, the mean age 22.38 +/- 1.34) were obtained.

Community noise annoyance assessment in an urban agglomeration.

In urban areas community noise is one of the important factors in producing deterioration of both well-being and the quality of life. The aim of the study was to compare two noise annoyance surveys and two noise annoyance scales in the period of 15 years in selected areas of Slovak capital Bratislava, to calculate risks of community noise annoyance and disturbance in the observed samples. Noise annoyance risks were calculated by bivariate and stratified analysis in the form of odds ratio and Mantel-Haenszel weighted odds ratio from 2x2 and 2xn tables.

Did the nutrition of Slovak medical students change? A comparison after 15 years.

Objective: Authors aimed at positive and negative changes evaluation in nutrition and nutritional status of university-medical students comparing the situation in years 1984 and 1999. They were trying to determine, how was the nutrition of current medical students influenced by food consumption changes in the Slovak population and price liberalization of the food-stuffs as well.

Material And Methods: Seven day reports from the year 1984 (199 students) and from the year 1999 (228 students) were processed using Food Research Institute, Food Composition Database and Programme.

A comparison of self-reported hearing loss and audiometry in a cohort of New York farmers.

The New York State Farm Family Health and Hazard Surveillance was conducted to assess the health status and safety practices among year-round adult farmers and farm residents in New York State and included a telephone interview survey of 1,727 persons from 552 farms. To determine the extent to which self-reported hearing loss is in agreement with audiometry, a subset of 376 participants who completed a hearing loss interview and pure-tone audiometry was analyzed. Thirty-six percent of the participants had self-reported hearing loss, defined as at least some difficulty hearing in one or both ears.

Community noise annoyance risk in two surveys.

Two noise annoyance surveys were performed in Bratislava, the capital of the Slovak Republic, in a ten-year interval (1989-1999). This was a period of political and socioeconomic transformation as well as of changes in traffic management. Equivalent noise levels were assessed at the dormitory (exposed group) and in the residential areas (100 measuring stations) where another group of students (control group) lived.

Predictors of hearing loss in New York farmers.

Background: Data from the telephone interview portion of the New York Farm Family Health and Hazard Surveillance were used to study self-reported hearing loss in New York farmers.

Methods: One thousand six hundred and twenty-two persons completed the hearing loss and noise exposure interview. Hearing loss was defined as at least some trouble hearing in one or both ears.
