Opis:
Introduction: The preparation of the patient for the collection of biological material for laboratory tests is one of the main factors determining the reliability of the results obtained. The values of the analyzed parameters are a source of information about their health and the basis for making therapeutic decisions on which the patient's health and life often depend. Aim: The aim of the study was to analyze knowledge of the comprehensive preparation for collecting biological material for laboratory tests and proceeding during and after this procedure. Material and method: The study was conducted on a group of 205 people (142 women and 63 men) in the period from October to December at one of Krakow ALAB Laboratories. A diagnostic survey method was used, using the author’s own questionnaire. Results: It was shown that the highest percentage of respondents presentend konwledge at a satisfactory level (48,8%). The general level of knowledge of the whole group was assesed as average with a significant part of people showing an unsatisfactory level of knowledge. The patients' self-assessment differed from the relatively low results of the knowledge test carried out and only patients with the lowest knowledge showed criticism of their assessment. Blood and urine tests were best known to patients as these tests were most often done by them. Conclusions: The conducted study showed that respondents, despite declaring knowledge of the procedures for preparing for research, to a large extent did not show sufficient knowledge on this subject. Thus there is a need to supplement knowledge deficits and broader interest in the issues discussed, as the level of patient knowledge depends to a large extent on the reliability of the results obtained.
Wstęp: Przygotowanie pacjenta do pobrania materiału biologicznego do badań laboratoryjnych jest jednym z głównych czynników warunkujących wiarygodność otrzymanych wyników. Wartości analizowanych parametrów są źródłem informacji o jego stanie zdrowia i podstawą do podejmowania decyzji terapeutycznych od których często zależy zdrowie i życie pacjenta. Cel: Celem pracy było zbadanie wiedzy pacjentów na temat prawidłowego przygotowania do pobrania materiału biologicznego do badań oraz postępowania w czasie i po zakończeniu tej procedury. Materiał i metoda: Badania przeprowadzono w grupie 205 osób (142 kobiet i 63 mężczyzn) w okresie od października do grudnia 2019 roku w jednym z krakowskich Punktów Pobrań ALAB Laboratoria. Zastosowano metodę sondażu diagnostycznego z wykorzystaniem autorskiego kwestionariusza ankiety. Wyniki: Wykazano, że największy odsetek respondentów prezentował wiedzę na poziomie zadowalającym (48,8%). Ogólny poziom wiedzy w całej grupie został oceniony jako średni, ze znacznym udziałem osób wykazujących niezadowalający jej poziom. Samoocena pacjentów odbiegała od stosunkowo niskich wyników przeprowadzonego testu wiedzy i jedynie pacjenci z wiedzą najniższą wykazali się krytycyzmem przy jej ocenie. Najlepiej poznanymi przez pacjentów były badania krwi i moczu i te rodzaje badań były przez nich najczęściej wykonywane. Wnioski: Respondenci pomimo deklarowania znajomości procedur przygotowania się do badań w dużej mierze nie wykazali się wystarczającą wiedzą na ten temat. Istnieje konieczność uzupełnienia deficytów wiedzy oraz szerszego zainteresowania omawianą problematyką, ponieważ od poziomu wiedzy pacjentów w dużym stopniu zależy wiarygodność otrzymanych wyników.

Opis:
In elements of steel structures working at low temperatures, there is a risk of appearance of brittle fracture. This risk is reduced through the use of certified materials having guaranteed strength at a given temperature. A method which is most frequently used to determine brittle fracture toughness is the Charpy impact test, preformed for a given temperature. For offshore structures intended to work in the arctic climate, the certifying institutions more and more often require Crack Tip Opening Displacement (CTOD) tests instead of conventional impact tests, especially for steel and welded joints of more than 40 mm in thickness in the case of high-strength steel, and more than 50 mm for the remaining steels. The geometry of specimens and the test procedure are standardised; however, these standards provide some margin for specimen notch depth. The paper analyses the effect of notch depth difference, within the range permitted by the standards, on the recorded CTOD values of a given material. The analysis was performed via numerical modelling of destruction of specimens with different notch geometries and further verification of the obtained numerical results in laboratory tests. The calculations were carried out at the Academic Computer Centre in Gdansk.

Opis:
Landing gears are one of the main components of an aircraft. The landing gear is used not only during take-off and landing but also, in most cases, during ground manoeuvres. Due to its function, the landing gear is also one of the key safety components of the aircraft due to dissipating landing loads acting on the aircraft. The mentioned loads come from both the vertical and horizontal speeds during touchdown and by the aircraft’s losing the speed by braking. The landing gear is then loaded with constantly changing forces acting in various directions during every landing, with the only difference coming from their magnitude. The repeatable loading conditions cause significant wear of the landing gear. This wear can be divided into two categories, one is the wear of consumable parts such as the brake linings and the other is the fatigue wear of the structural components. The latter type of wear is much more dangerous due to its slow, and in many cases, unnoticeable progression. Fatigue wear can be estimated by numerical analyses - this method works with a great degree of probability on single components but due to the complexity of the landing gear as a whole it is not precise enough to be applied to the full structure. In order to evaluate the fatigue of the whole landing gear the best method accepted by regulations is the laboratory testing method. It involves a series of various drop tests resembling the real landing condition distribution. The aim of the tests is to check the fatigue wear of the landing gear and to prove its reliability for certification and/or operational purposes. In this paper the author describes the basics of the landing gear fatigue wear, possibilities of its evaluation and presents laboratory dynamic method used for extensive tests in life-like operation conditions.

Opis:
This article presents selected issues related to the selection methodology of the brake linings during the research process. It is a very important issue due to effect on the vehicle safety. Safety concerns are applicable to both road/track vehicles and aircraft. Scientific institutions and research centers make continuous efforts in order to improve brake lining materials and full-scale brakes. Analytical prediction of the friction material properties and behavior is not accurate enough due to complexity of the physical phenomena. Analysis of the friction materials is difficult due to scarce of data given by the manufacturers. Every friction material needs to be tested in order to prove its properties. First stage of the selection is the tests made in laboratory using both model and full-scale techniques. Because of the laboratory tests, following parameters are obtained: weight and geometrical brake wear, braking torque, friction coefficient and brake temperature. All of these factors must be taken into account for linings selection and design a prototype of the brake. Selection of the friction material can be performed in consideration of various requirements of the brake system users and law defined factors. Authors of the paper base on the extensive experience of the Institute of Aviation, Landing Gear Laboratory tests of brake linings.

Opis:
This article presents the execution and results of tests of the loading efficiency of wormtype cutting drums as a function of the slope of a longwall working. The tests were carried out at various angles of longitudinal inclination of a longwall within a range of 0 degrees to 9 degrees along the strike. In real conditions, the separation of the two basic processes that take place during operation of a longwall shearer (i.e., milling and loading) is not possible; therefore, the research was carried out under laboratory conditions at the Department of Mining, Dressing, and Transport Machines at AGH University of Science and Technology in Krakow. The tests were carried out on a special station that allowed for the gradual change of the longitudinal and transverse slope of a longwall working. Based on the conducted tests, it was found that the inclination of a longwall working influences the loading efficiency; i.e., that, along with an increase in the angle of the longitudinal inclination, loading resistance increases while the loading efficiency decreases.

Opis:
Laboratory tests are the cheapest and easily accessible source of medical information about a patient. Although they make an important and frequently decisive element of the diagnostic and therapeutic process, the expenditure on tests in Poland is many times lower than that in other countries of the European Union. The Supreme Audit Office, in accordance with its work plan and guided by the suggestions of the Parliamentary Health Committee, has conducted an audit to evaluate the organisation, quality, access to and financing of the activities related to laboratory diagnostics. The audit comprised: the Ministry of Health, medical entities and laboratory diagnostics subcontractors, including medical diagnostic laboratories in six regions of Poland.

Opis:
This paper discusses the pull-out laboratory tests and the monitoring of expansion-shell bolts with a length of 1.82 m. The bolts comprised the KE-3W expansion shell, a rod with a diameter of 0.0183 m and a profiled, circular plate with a diameter of 0.14 m, and a gauge of 0.006 m. The bolts were installed in a concrete block with a compressive strength of 75 MPa. The tests were conducted on a state-of-the-art test stand owned by the Department of Underground Mining of the AGH University of Science and Technology. The test stand can be used to test roof bolts on a geometric scale of 1:1 under static and rapidly varying loads. Also, the stand is suitable for testing rods measuring 5.5 m in length. The stand has a special feature of providing the ongoing monitoring of bolt load, displacement and deformation. The primary aim of the study was to compare the results recorded by two different measurement systems with the innovative Self-Excited Acoustic System (SAS) for measuring stress variations in roof bolts. In order to use the SAS, a special handle equipped with an accelerometer and exciter mounted to the nut or the upset end of the rod was designed at the Faculties of Mining and Geoengineering and Mechanical Engineering and Robotics of the AGH University of Science and Technology. The SAS can be used for non-destructive evaluation of performance of bolts around mining workings and in tunnels. Through laboratory calibration tests, roof bolt loads can be assessed using the in-situ non-destructive method.

Opis:
Assigning transported material with a supplementary information is becoming relevant for the needs of improving the efficiency of industrial processes. In the mining industry annotating the mined ore could bring benefits due to expected decrease of the processing energy consumption and increase of productivity. DISIRE project was focused on the implementation of e-pellets for various raw material processing and transportation processes. The paper presents laboratory tests of altern ative RFID equipment for annotating ore with marked tags. Several aspects of tags traceability were investigated for the needs of the industrial tests that were eventually done in the underground mine environment. The laboratory tests results were compared with the similar tests described in the literature, that were done in the different conditions.
