Opis:
Introduction and objectives. Insect stings are the second trigger of anaphylaxis in children and adolescents, causing a potentially life-threatening reactions. Hence health-related quality of life (HRQoL) is an important issue for Hymenoptera venom allergy (HVA) patients. The aim of this cross-sectional study was to evaluate the impact of HVA on young patients’ HRQoL, including their socio-demographic characteristics. Materials and method. The study sample included 102 patients aged 8–17 (Mean 12.5 years, SD=3.0), who were under diagnosis or venom immunotherapy due to systemic reaction after an insect sting in one of the tertiary referential centers in Poland. They were mostly boys (70%), and mainly from rural areas (63%). HRQoL of studied patients was measured with the Children’s Hymenoptera Venom Allergy Quality of Life Scale, a questionnaire covering 6 dimensions: anxiety, caution, limitations, discomfort, support received from parents and a feeling of safety, each measured from 1 to 5. Independent predictors of HRQoL were estimated using the Generalized Linear Model. Results. In the group of children being dermal reactors, girls reported a higher level of anxiety (B=1.17, 95%CI=(0.30;2.03), p=0.008). In the group of children with grade 2 it was the girls who reported lower anxiety (B=-1.33, 95%CI=(-2.38;-0.29), p=0.013). Boys treated longer than 3 years had their level of anxiety significantly lower than those studied at diagnosis (B=-0.65, 95%CI=(-1.23;-0.07), p=0.028). The feeling of safety was higher in children living in villages than in those living in towns (B=0.30, 95%CI=(0.03;0.56), p=0.031). Conclusions. The gender, treatment duration and stage of anaphylactic reaction influenced level of anxiety. The level of feeling of safety was related to the place of living.

Opis:
Introduction. Air pollution is one of the most important issues of our times. Air quality assessment is based on the measurement of the concentration of substances formed during the combustion process and micro-particles suspended in the air in the form of an aerosol. Microscopic atmospheric particulate matters (PM) 2.5 and 10 are mixtures of organic and inorganic pollutants smaller than 2.5 and 10 μm, respectively. They are the main cause of negative phenomena in the earth’s atmosphere of Earth and human health, especially on the respiratory and cardiovascular systems. Particulates have the ability to cause permanent mutations of tissue, leading to neoplasms and even premature deaths. Nitrogen dioxide (NO2) is one of the main pollutants which arises mainly during the burning of fossil fuels. Based on numerous scientific researches, it has been proved that long-term exposure to NO2 could increase morbidity of cancer due to inflammatory processes increasing abnormal mutations. Materials and method. Data available in the Polish National Cancer Registry, Chief Inspectorate for Environmental Protection and Map of Health Needs in the Field of Oncology for Poland, WHO Air Quality Guidelines 2005 were analyzed. Air pollution was also evaluated: PM2.5, PM10, NO2, and compared with lung cancer morbidity. Results and conclusions. Based on the available data and literature, it can be concluded that in 2009–2017, on average, each Pole smoked ten cigarettes a day +/- 2. Therefore, it can be estimated that after 60 years everyone had 30 package-years of smoking, leading to a high risk of lung cancer and other smoking related diseases. Additionally air quality in Poland is not satisfactory, exceeding the standards presented in the WHO Guidelines 2005. It can be assumed that this may translate into an additional, independent continuous increase in morbidity and mortality dependent on smoking.

Opis:
Introduction and objectives. The study aimed at evaluating the impact of Hymenoptera venom allergy (HVA) in children and adolescents, on their parents’ QoL, taking into account their socio-demographic characteristics. Materials and method. The study sample consisted of 101 parents of children and adolescents aged 9–17 years, with a history of systemic reaction after insect sting who were referred for consultations in the tertiary level allergology department. The mean age of the parents was 39 years (SD=8.1; range 25–65 years); the majority were mothers (68%) and rural inhabitants (62%). QoL in parents of HVA children and adolescents was measured with the Parents of Children with Hymenoptera Venom Allergy Quality of Life Scale, a questionnaire covering 5 dimensions: anxiety, caution, limitations and discomfort, support provided to the child and feeling of safety, each measured on the scale ranging from 1 to 5. Independent predictors of QoL were estimated using the Generalized Linear Model. Results. Parents of urban children and adolescents treated with venom immunotherapy (VIT) up to 3 years (B=-1.37, 95CI= (-2.22;-0.53); p=0.001) and of rural children treated for more than 3 years (B=-0.94, 95CI=(-1.55;-0.33); p=0.003) reported lower anxiety than parents studied at diagnosis. In urban parents, individuals studied at VIT beginning reported a lower feeling of safety (B=-0.63, 95CI=(-1.11;-0.15); p=0.010); those studied up to 3 years of treatment reported a higher feeling of safety (B=0.64, 95CI=(0.11;1.16); p=0.018) than those studied at diagnosis. Contrariwise, in rural parents, those studied at the beginning of immunotherapy reported a higher feeling of safety than those studied at diagnosis (B=0.51, 95CI=(0.13;0.88); p=0.008). Conclusions. The longest VIT duration in children and adolescents with HVA is related to the decreased anxiety of their parents. Parent’s feeling of safety depends on the stage of treatment and place of residence.

Opis:
Artykuł omawia proces tworzenia trójwymiarowego modelu ostańca jako metody inwentaryzacji pomników przyrody nieożywionej. Przedmiotem badań był jeden z najbardziej znanych pomników przyrody nieożywionej w Polsce, jakim jest Maczuga Herkulesa znajdująca się w Ojcowskim Parku Narodowym. Model 3D skałki powstał na podstawie danych geometrycznych, które pozyskano przy wykorzystaniu naziemnego skaningu laserowego (TLS). Technologia ta jest z powodzeniem stosowana między innymi do dokumentacji zabytków, zarówno pochodzenia antropogenicznego (budowli, dzieł sztuki), jak i pomników przyrody. W celu stworzenia modelu Maczugi Herkulesa zaplanowano i przeprowadzono pomiar skanerem laserowym Leica Scan-Station C10. Dodatkowo podczas prac terenowych założono i pomierzono osnowę geodezyjną przy wykorzystaniu metody tachimetrycznej i satelitarnej. Miało to na celu dokładne zlokalizowanie obiektu w państwowym systemie odniesień przestrzennych oraz późniejsze nadanie punktom modelu współrzędnych w geodezyjnych układach odniesienia. Prace kameralne obejmowały stworzenie modelu 3D ostańca na podstawie pozyskanej chmury punktów reprezentującej cały obiekt. Wynikowa chmura punktów i utworzony model 3D mogą w przyszłości służyć jako dane pierwotne potrzebne do badania okresowych zmian geometrii ostańca. W artykule wykazano, że zastosowana metodyka pozyskiwania danych przestrzennych przy wykorzystaniu naziemnego skaningu laserowego pozwala na zarówno szybkie, jak i wierne odwzorowanie geometrii rzeczywistego obiektu w postaci trójwymiarowego modelu numerycznego.
This article discusses the process of creating a three-dimensional model of a rock as an inventory method of inanimate nature monuments. The subject of the research was one of the best-known monuments of inanimate nature in Poland, namely the Maczuga Herkulesa situated in the Ojcowski National Park. The 3D model of the rock was created on the basis of geometric data which was acquired with the usage of Terrestrial Laser Scanning. This technology has been successfully applied, among others things, to document monuments, both of anthropogenic (buildings, works of arts) and natural origin. In order to create a model of the Maczuga Herkulesa rock, the measurements by means of Leica ScanStation C10 laser scanner was planned and conducted. Additionally, a control network was created and measured during field works by means of tacheometric and satellite methods. It was aimed at the precise localisation of the object in the National Spatial Reference System, as well as at marking the points of the model with coordinates in the current reference systems. The analysis included the creation of a 3D model of the rock on the basis of the obtained point cloud representing the whole object. In the future, the point cloud and the created 3D model can serve as initial data, which are necessary in order to define periodic changes in monadnock geometry. It was proved in the article that the applied method of acquiring spatial data by means of terrestrial laser scanning enables both fast and accurate transfer of the real object’s geometry to a three-dimensional numeric model.

Opis:
Various types of waste materials containing zinc (e.g. dusts and sludges from gas dedusting process) are obtained in steel industry. The contents of Zn in these materials may vary considerably. Even a low concentration of zinc in recirculated products precludes their recycling in ferrous metallurgy aggregates. Long storage of this type of material can lead to contamination of soil and water by zinc compounds which can be leached out by acid rain, for example. This paper focuses on research involving alkaline leaching tests of low zinc content iron-bearing materials. These tests were preceded by the analysis of the elemental, phase and grain size composition, and analysis of the thermodynamic conditions of the leaching process. The main aim of research was to decrease the content of the zinc in the sludge to the level where it is suitable as an iron-bearing material for iron production (~1% Zn). Leaching at elevated temperatures (368 K, 60 min) has led to a decrease in the zinc content in the sludge of about 66%. The research revealed that long hour leaching (298 K, 100 hours) carried out at ambient temperatures caused a reduction in zinc content by 60% to the value of 1.15-1.2% Zn.

In modern machining industry, the use of computer software is an integral element in the design of technological processes. This work aims to present possibilities for optimization of milling operations with the use of commercial software designed especially for that use. A face milling operation of an aluminium flange was chosen for this study. Several different optimization strategies were described and their results shown, analysed and discussed. The effect of variable radial depth of cut on cutting force values in milling processes was reflected upon. Additionally, further research involving comparison of experiment results with simulation was proposed. It was proven that correct optimization strategy can reduce machining time for the analysed face milling operation about 37% without exceeding imposed process parameter constraints.

In this article, a novel approach to computer optimization of CNC toolpaths by adjustment of cutting speed vcand depth of cut apis presented. Available software works by the principle of adjusting feed rate on the basis of calculations and numerical simulation of the machining process. The authors wish to expand upon this approach by proposing toolpath optimization by altering two other basic process parameters. Intricacies and problems related totheadjustment of apand vcwere explained in the introductory part. Simulation of different variant of the same turning process with different parameter values were conducted to evaluate the effect of changes in depth of cut and cutting speed on process performance. Obtained results were investigated on the account of cutting force and tool life. The authors have found that depth of cut substantially affects cutting force, while the effect of cutting speed on it is minimal. An increase in both depth of cut and cutting speed affects tool life negatively, although the impact of cutting speed is much more severe. An increase in depth of cut allows for a more significant reduction of machining time, while affecting tool life less negatively. On the other hand, the adjustment of cutting speed helpsto reduce machining time without increasing cutting force component values and spindle load.

Opis:
Currently, process optimization is an important part of design of CNC toolpath, allowing overall process improvement in accordance to a range of criteria. Available CAE software for CNC toolpath optimization works only by changing the feed rate value specified in the base toolpath. The authors are planning to devise a solution allowing for optimization of other process parameters, including depth of cut. In some cases, it would be important for surface roughness to remain unaltered after optimization by means of increasing depth of cut. In this work, the effect of depth of cut on surface roughness was investigated. Depth of cut was altered for the roughing pass, while technological parameters for the finish pass remained constant. Roughness measurements were performed on-machine after rough turning and finish turning. The authors have found that depth of cut has a noticeable effect on investigated roughness parameters, both in the case of rough turning and subsequent finish turning operations.

Studies conducted in the years 2014-2015 were designed to evaluate of soil fertility from 22 organic farms specializing in the cultivation of strawberries and raspberries from the south-eastern Poland. Evaluated soil sampled in 56 different plantation of strawberries and raspberries. Soil pH was determined in distilled water (pHH2O). Soil fertility determined in the extract of 0.03 M CH3COOH and the content of available forms of nitrate nitrogen (N-NO3), phosphorus (P-PO4), potassium (K), calcium (Ca) and magnesium (Mg) were expressed in mg dm-3 as well as in mg 100g-1 dry soil. In addition in soil samples salinity was determined expressed as g NaCl dm-3. Analysis of the results obtained in the studies showed that the pH of the soils studied (pHH2O) was in the range 4.60-7.60. The content of macronutrients in the soils contained in compartments (mg dm-3): ˂10.0-19.8 N-NO3, 2.0-33.0 P-PO4, 10.0-239.0 K, 107.0-3930.0 Ca, 26.0-134.0 Mg.
Badania przeprowadzone w latach 2014-2015 miały na celu ocenę zasobności gleb w 22 gospodarstwach ekologicznych specjalizujących się w uprawie truskawki i maliny, zlokalizowanych w południowo-wschodniej Polsce. Badaniom poddano 56 prób glebowych z plantacji truskawki i maliny. Odczyn gleby (pH) oznaczono w wodzie destylowanej (pH H2O). Zasobność gleby określano w ekstrakcie 0,03 M CH3 COOH, a zawartości dostępnych form azotu azotanowego (N-NO3), fosforu (P-PO4), potasu (K), wapnia (Ca) i magnezu (Mg) wyrażono w mg∙dm-3, jak również w mg∙100g-1suchej gleby. Ponadto w próbkach glebowych określono poziom zasolenia wyrażony jako g NaCl dm-3. Analiza wyników uzyskanych w badaniach wykazała, że odczyn badanych gleb (pH H2O) zawierał się w zakresie od 4,60 do 7,60. Zawartość makroskładników w badanych próbkach gleb zawierała się w przedziale (mg∙dm-3): ≤10,0-19,8 N-NO3, 2,0-33,0 P-PO4, 10,0-239,0 K, 107,0-3930,0 Ca, 26,0-134,0 Mg.

Opis:
Apart from accuracy, one of the parameters describing industrial robots is positioning accuracy. The parameter in question, which is the subject of this paper, is often the decisive factor determining whether to apply a given robot to perform certain tasks or not. Articulated robots are predominantly used in such processes as: spot welding, transport of materials and other welding applications, where high positioning repeatability is required. It is therefore essential to recognise the parameter in question and to control it throughout the operation of the robot. This paper presents methodology for robot positioning accuracy measurements based on vision technique. The measurements were conducted with Phantom v2511 high-speed camera and TEMA Motion software, for motion analysis. The object of the measurements was a 6-axis Yaskawa Motoman HP20F industrial robot. The results of measurements obtained in tests provided data for the calculation of positioning accuracy of the robot, which was then juxtaposed against robot specifications. Also analysed was the impact of the direction of displacement on the value of attained pose errors. Test results are given in a graphic form.
