    Opis:
    Introduction: The article presents a selected part of an analysis of health- and lifestyle-related determinants of the longevity of male residents of the city of Łódź. The WHO strategy for the European region assumes that the term ‘lifestyle' refers to the way of life based on the association between conditions of life understood in a broad sense and individual patterns of behaviour determined by socio-cultural factors and individual features. On this basis, the aim of this study is to identify the multiple statistical relationships on the mortality of men living in Łódź, particularly the influence of the following variables on the probability of survival: age, subjective health assessment, nutritional habits, alcohol consumption and tobacco smoking. Materials and Methods: The study sample (1004 respondents) was selected, and the study was carried out, based on the standards of the CINDI WHO Programme. The investigations included socio-demographic data, health status, lifestyle and anthropometric measurements. Results: From the results of the first- study performed in Poland of the longevity of men with identified risk factors of cardiovascular diseases, it has been found that: 1) Tobacco smoking has a negative influence on male longevity; 2) Alcohol consumed in moderate amounts favours male longevity; 3) The level of physical activity observed among the studied men was too low to affect longevity; 4) A diet rich in fish and consumption of yellow cheese are positive predictors of longevity, while additional use of table salt at meals and consumption of sweets (cakes) are negative ones. Conclusions: Risky lifestyles and a reluctance to abandon them are responsible for a shorter lifespan among men in Poland. Reducing this difference between women and men is a real challenge for public health professionals and preventive medicine specialists.

    Opis:
    The paper presents a low noise voltage FET amplifier for low frequency noise measurements. It was built using two stages of an op amp trans impedance amplifier. To reduce voltage noise, eight-paralleled low noise discrete JFETs were used in the first stage. The designed amplifier was then compared to commercial ones. Its measured value of voltage noise spectral density is around 24 nV/√Hz, 3 nV/√Hz, 0.95 nV/√Hz and 0.6 nV/√Hz at the frequency of 0.1, 1, 10 and 100 Hz, respectively. A -3dB frequency response is from ~20 mHz to ~600 kHz.

    Opis:
    The paper presents noise measurements in low-resistance photodetectors using a crosscorrelation-based transimpedance amplifier. Such measurements usually apply a transimpedance amplifier design to provide a current fluctuation amplification. In the case of low-resistance sources, the measurement system causes additional relevant system noise which can be higher than noise generated in a tested detector. It mainly comes from the equivalent input voltage noise of the transimpedance amplifier. In this work, the unique circuit and a three-step procedure were used to reduce the floor noise, covering the measured infrared detector noise, mainly when operating with no-bias or low-bias voltage. The modified circuit and procedure to measure the noise of unbiased and biased detectors characterized by resistances much lower than 100 Ω were presented. Under low biases, the reference low-resistance resistors tested the measurement system operation and techniques. After the system verification, noise characteristics in low-resistance InAs and InAsSb infrared detectors were also measured.

    Opis:
    W pracy przedstawiono wyniki pomiarów gęstości widmowej napięcia szumów detektorów fotonowych o małych rezystancjach przy użyciu specjalnie opracowanego stanowiska pomiarowego. Badania tych detektorów mają duże znaczenie dla wielu aplikacji. Są one szczególnie istotne dla układów laserowej spektroskopii absorpcyjnej do wykrywania śladowych ilości gazów. Uzyskiwana w nich granica wykrywalności jest bezpośrednio związana nie tylko z szumami źródeł promieniowania i szumem tła, lecz także z szumami detektora oraz kolejnych stopni fotoodbiornika. Zastosowanie w opracowanym systemie specjalnie zaprojektowanych ultramałoszumowych torów pomiarowych (wzmacniacze o napięciu szumów 3,6 × 10⁻¹⁹ V² /Hz dla f > 1 kHz) oraz operacji korelacji sygnałów w czasie 10 minut umożliwiło uzyskanie szumu tła poniżej 10⁻¹⁸ V² /Hz dla f > 10 Hz oraz poniżej 10⁻¹⁹ V² /Hz dla f > 1 kHz. Efektywność systemu zweryfikowano poprzez pomiary referencyjnych rezystorów, a następnie detektora z supersieci drugiego rodzaju (T2SL) wykonanego z InAs/InAsSb.
    The paper presents noise measurements of low-resistance photon detectors with a specially developed system. These measurements are significant for many applications. This issue is particularly critical for laser absorption spectroscopy systems to detect trace amounts of gases. In these systems, the detection limit is determined by noise origins, e.g., light source, background, and detector noise and its readout electronics. The use of some specially designed components of the system (low-noise - 3.6 × 10⁻¹⁹ V² /Hz for f >1 kHz) cross-correlation signal processing provides to obtain a measuring floor noise below 10⁻¹⁸ V² /Hz for f > 10 Hz and below 10⁻¹⁹ V² /Hz for f > 1 kHz after ten minutes’ analysis. Measurements of some reference resistors have verified the system’s performance. Finally, the system was also applied to determine the spectral noise density of the II-Type SuperLattice photodetector made of InAs/InAsSb.

    Opis:
    Introduction: It is still uncertain if having at least moderate physical fitness is a necessary and sufficient condition for lowering the risk of death. The aforementioned statement constituted the basis for undertaking the study concerning the effect of particular health-related behaviours on the likelihood of survival in subjects with a moderate and high physical fitness. Materials and Methods: The study sample, i.e. 204 men aged 30-59 years living in Łódź, Poland, was selected within the CINDI WHO Programme and examined over the years 1980-1990 and 2003-2004. In each subject approximate values of one week energy expenditures associated with performing physical exercise of at least moderate intensity (> 1000 kcal/week) were estimated. Physical efficiency in the study group was evaluated basing on the results of the submaximal effort test. Information about selected socio-demographic characteristics, consumption of alcohol, cigarette smoking and diet was gathered. The vital status of the examined sample was checked in 2009. The Cox proportional hazards regression model was used to identify factors which influence the survival of examined population. Results: The probability of death was more than fourfold higher in the case of individuals who eat "beef or pork meat", as compared to those who consumed these products rarely or never. On the other hand, the subjects who declared regular consumption of yellow cheese had nearly fourfold lower death probability. Current smoking was found to be a significant negative risk factor while moderate consumption of beer a protective one. The level of physical fitness ($\text{V}_\text{O2max}$) did not significantly influence mortality. Conclusions: The results of the performed analyses indicate negative effect associated with consumption of beef/pork meat and smoking. Furthermore, the data pertaining to the consumption of yellow cheese as a potent protective factor for men's health requires further verification. The possibility that it is some lifestyle proxy rather than a causal factor can not be excluded.

    Opis:
    The paper is a review of analog and digital electronics dedicated to monitor nanosecond pulses. Choosing the optimal peak detector construction depends on many factors for example precision, complexity, or costs. The work shows some virtues and limitations of selected peak detection methods, for example standard peak detector with rectifier, sample and hold circuit with triggering units and ADC fast acquisition. However, the main attention is paid to problems of results from effective triggering signal for sample and hold operation. The obtained results allow for designing a peak detector construction as an alternative for costly and very complex fast acquisition systems based on ADC and FPGA technologies.

    Opis:
    The paper presents verification of a peak detection method cooperating with infrared radiation detector module applications. The work has been divided into parts including SPICE simulations and presentation of results obtained with the constructed prototype. The design of the peak detector dedicated to applications with very short pulses requires a different approach than that for standard solutions. It is mainly caused due to the ratio of pulse width and time period. In the described application this ratio is less than 10%. The paper shows testing of an analogue circuit which is capable to be inserted in these applications.

Opisano detektory stosowane w LAS i pomiar szumów. Zwrócono uwagę na trudność w przeprowadzeniu dokładnych pomiarów szumów w zakresie małych częstotliwości, szczególnie dla detektorów IR o małych rezystancjach, dlatego też opracowano specjalny system pomiarowy. Następnie przedstawiono opis systemu pomiarowego i wyniki pomiarów. Wykazano, że uzyskany poziom szumów własnych umożliwia pomiar szumów termicznych rezystancji o wartości powyżej 10 Ω. Badania te są istotne dla układów laserowej spektroskopii absorpcyjnej do wykrywania śladowych ilości gazów.

    This paper presents some construction analysis and test results of a Free Space Optics system operating at the wavelength of 9.35 μm. In the system, a quantum cascade laser and a photoreceiver with mercury cadmium telluride photodetectors were used. The main parameters of these elements were discussed taking into account a data link operation. It also provides to determine a data range for various weather conditions related to scattering and scintillation. The results of numerical analyses defined the properties of currently available FSO technologies working in the near infrared or in the short infrared range of spectrum versus the performances of the developed system. The operation of this system was verified in three different test environments. The obtained results may also contain important issues related to the practical application of any FSO system.

    Opis:
    The review includes results of analyses and research aimed at standardizing the concepts and measurement procedures associated with photodetector parameters. Photodetectors are key components that ensure the conversion of incoming optical radiation into an electrical signal in a wide variety of sophisticated optoelectronic systems and everyday devices, such as smartwatches and systems that measure the composition of the Martian atmosphere. Semiconductor detectors are presented, and they play a major role due to their excellent optical and electrical parameters as well as physical parameters, stability, and long mean time to failure. As their performance depends on the manufacturing technology and internal architecture, different types of photodetectors are described first. The following parts of the article concern metrological aspects related to their characterization. All the basic parameters have been defined, which are useful both for their users and their developers. This allows for the verification of photodetectors’ workmanship quality, the capabilities of a given technology, and, above all, suitability for a specific application and the performance of the final optoelectronic system. Experimentally validated meteorological models and equivalent diagrams, which are necessary for the correct analysis of parameter measurements, are also presented. The current state of knowledge presented in recognized scientific papers and the results of the authors’ works are described as well.

    Objectives The role of leisure-time physical activity in reducing all-cause and cardiovascular mortality is well explored. The knowledge on occupational and commuting physical activity continues to be ambiguous and misleading. The aim of the study is to assess the influence of different kinds of physical activity on cardiovascular mortality risk in men. Material and Methods Data analysis on physical activity level and other selected cardiovascular risk factors acquired from 3577 men in the age between 50–80 years who participated in the National Multicenter Health Survey WOBASZ (Wieloośrodkowe Ogólnopolskie Badanie Stanu Zdrowia), Poland (2003–2005) was linked with male mortality in 2004–2009. Data about causes of deaths were obtained from the Central Statistical Office and the Population Electronic Register. Results Among males aged 50–59 years, the strongest risk factor was living in large settlements and provincial capitals as a place of residence and the most protective factor was occupational physical activity. In the age group 60–69 years and 70–80 years, the strongest protective effect was observed for leisure-time physical activity. In men aged between 70–80 years (unlike in the 50–59 years age group), the protective effect of large settlements and provincial capitals as a place of residence was noted. Conclusions Occupational physical activity significantly reduced cardiovascular mortality in men aged 50–69 years, while for leisure-time activity the positive effect was observed in age group 60–69 years and 70–80 years. On the other hand, for the inhabitants of large settlements and provincial capitals, significantly higher risk of cardiovascular mortality in the age group 50–69 years and lower risk in the age group ≥ 70 years was noted, both in comparison with smaller places of residence.

    Abstract. An elevation in plasma cardiac troponins is an indicator of increased perioperative risk in orthopaedic and vascular surgery, however, data on liver transplantation (LTx) are scarce. The aim of the study was to evaluate the prevalence of cardiac troponin I (cTnI) elevation in the perioperative period of LTx, and its potential relationship with 1-year mortality. Material and methods. Analysis included 79 patients with liver cirrhosis. During LTx all patients underwent hemodynamic measurements. cTnI level was determined before the operation, 24, 48 and 72 hours afterwards. One-year mortality was assessed. Results. 12.7% patients died, all during in-hospital period. cTnI level on day 1. was identified as the most promising marker of increased death risk with optimal cut-off value of 0.215 ng/mL (the sensitivity of 60.0%, specificity of 87.0%, positive predictive value of 40.0%, negative predictive value of 93.8%). The most important predictor of cTnI increase was the duration of the LTx procedure followed by amount of packed red blood cells transfused, basic stroke volume index, and cardiac output index. In conclusion: value of cTnI level assessed 24 hours post-surgery was a reliable predictor of death following LTx with optimal cut-off value of 0.215 ng/mL. The surgery time was the most important predictor of cTnI elevation.
