Opis:
Introduction. The aim of presented study was comparison of urinary 1-hydroxypyrene concentration among coke plant workers (before and after working week) and among non-exposed individuals from the same area, taking smoking status into consideration. Materials and method. 647 coke plant workers and 206 individuals living in the same area were analysed with respect to urinary 1-OHP concentration and smoking status. Urinary samples were measured using high performance liquid chromatography (HPLC) with fluorescent detection. Concentrations were normalized with respect to creatinine concentration. For workers, two samples were collected before and after working week. Multiple regression was performed to distinguish and quantify the influence of cigarette smoking and occupational PAH exposition on the urinary 1-OHP levels. Results. Average urinary 1-OHP concentration of samples collected before the working week was: 1.07 μg/g; after the working week: 2.36 μg/g and for control: 0.74 μg/g. The samples collected at the beginning of the working week were not suitable for assessment of the workers’ background (non-occupational) exposition. Smoking cigarettes induced a rise in urinary 1-OHP level by 16%, on average (CI: 5% – 28%), and working for a whole working week at the coke plant made urinary 1-OHP levels, on average, 3.21 times higher (CI: 2.91 – 3.54). Conclusions. Working at the coke plant increases significantly urinary 1-OHP concentration in comparison to nonoccupationally exposed individuals, both for samples collected before and after the working week. Smoking remains a significant source of PAHs exposition, despite the fact that occupational exposure is greater. Health promotion programmes should address both the occupational health risks reduction and smoking prevention.

Opis:
We present an investigation of optical and electrical properties of mid-wavelength infrared (MWIR) detectors based on InAs/GaSb strained layer superlattices (SLs) with nBnN and pBnN design. The temperature-dependent behavior of the bandgap was investigated on the basis of absorption measurements. A 50% cut-off wavelength of around 4.5 μm at 80 K and increase of up to 5.6 μm at 290 K was found. Values of Varshni parameters, zero temperature bandgap E0 and empirical coefficients α and β were extracted. Arrhenius plots of dark currents of nBnN and pBnN detectors were compared with the p-i-n design. Dark current density reduction in nBnN and pBnN detectors is observed in comparison to the p-i-n device. This shows a suppression of Shockley-Read-Hall (SRH) processes by means of introducing barrier architecture.

Opis:
The paper presents the circular Hough transform in the process of detecting and counting coins. The issues of linear and circular Hough transform are discussed. An algorithm for counting coins in a three-dimensional image using the discrete Hough space is demonstrated. Moreover, the results of the application for detecting and counting coins in a static image and video stream are presented. Observations of histograms for HSV and RGB color palettes, for different camera resolutions and various parameters of image segmentation, edge detection and smoothing filter have been made.

Opis:
In the paper, there is presented the comparison of the quality of three-dimensional object measurement by scanning devices using a coherent light beam and a structured light field. Several selected issues from the fringe pattern analysis, as well as the characteristics of terrestrial laser scanning are also presented. The comparative analysis was performed to scan a crankshaft in order to assess the measurement accuracy of both scanners. By applying the appropriate software for the resulting point clouds we created a three-dimensional model of the crankshaft and made adequate comparative measures.
