Opis:
Ship’s bridge simulators are very popular in the worldwide training and assessment of merchant navy deck officers. The examiners of simulator courses presently do not have a method to quantitatively assess the performance of a group or an individual. Some examiners use checklists and others use their gut feeling to grade competence. In this paper a novel methodology is established that uses the Evidential Reasoning algorithm to quantitatively assess the Non-Technical Skills (NTS) of merchant navy officers. To begin with, interviews were conducted with experienced deck officers to develop the taxonomy and behavioural markers that would be used in the assessment process. A random selection of students studying towards their Chief Officer’s Certificate of Competency were recruited to have their NTS to be observed in a ship’s bridge simulator. The participant’s behaviour was rated against five criteria and the subsequent data was entered into the Evidential Reasoning algorithm to produce a crisp number. The results that were generated demonstrate that this approach provides a reliable method to quantitatively assess the NTS performance of merchant navy officers in a simulated bridge environment.

Opis:
A review of maritime accidents conducted over the last decade confirms that human error is the main contributing factor in these incidents. Well‐developed Non‐Technical Skills (NTS) can reduce the effects of human error. NTS include both interpersonal and cognitive skills such as situation awareness, teamwork, decision‐making, leadership, managerial skills, communication and language skills. In a crisis situation good NTS allow a deck officer to recognise the problem quickly, take action to manage the situation, and utilise the available team members safely and effectively. This paper identifies the importance of NTS training for merchant navy deck officers. It also highlights room for improvement in the existing HELM training. Research has shown that at present the structure of HELM training is not very effective. The other safety critical domains’ efforts into NTS developments are investigated and examples of best practice are adapted into the maritime domain’s NTS training. Suggestions are given for improvements to the HELM course based on proven successful methods in other safety critical domains (aviation and anaesthesia). A subsequent Cost Benefit Analysis for improving deck officers’ NTS is also carried out through the use of Bayesian Networks and Decision Tree Modelling.

Opis:
This study deals with numerical modeling of passive autocatalytic hydrogen recombiners (PARs). Such devices are installed within containments of many nuclear reactors in order to remove hydrogen and convert it to steam. The main purpose of this work is to develop a numerical model of passive autocatalytic recombiner (PAR) using the commercial computational fluid dynamics (CFD) software ANSYS-FLUENT and tuning the model using experimental results. The REKO 3 experiment was used for this purpose. Experiment was made in the Institute for Safety Research and Reactor Technology in Julich (Germany). It has been performed for different hydrogen concentrations, different flow rates, the presence of steam, and different initial temperatures of the inlet mixture. The model of this experimental recombiner was elaborated within the framework of this work. The influence of mesh, gas thermal conductivity coefficient, mass diffusivity coefficients, and turbulence model was investigated. The best results with a good agreement with REKO 3 data were received for k-ε model of turbulence, gas thermal conductivity dependent on the temperature and mass diffusivity coefficients taken from CHEMKIN program. The validated model of the PAR was next implemented into simple two-dimensional simulations of hydrogen behavior within a subcompartment of a containment building.

Opis:
A lumped parameter type code, called HEPCAL, has been worked out in the Institute of Thermal Technology of the Silesian University of Technology for simulations of a pressurized water reactor containment transient response to a loss-of-coolant accident. The HEPCAL code has been already verified and validated against available experimental data, which in fact have been taken from separate effect tests mainly. This work is devoted to validation of the latest version of the HEPCAL code against experimental data from more complex tests. These experiments have been performed on three different test rigs (called TOSQAN,MISTRA and ThAI) and a part of them became the basis of the International Standard Problem No. 47 (ISP-47) dedicated to containment thermal-hydraulics. Selected experiments realized within the framework of the ISP-47 project have been simulated using the HEPCAL-AD code. The obtained results allowed for drawing of some important conclusions concerning heat and mass transfer models (especially steam condensation), two-phase flow model and buoyancy effects.

Opis:
The article presents results of research work which aim was development of solution for volatile organic compounds (VOCs) removal from vehicle indoor air. VOCs, especially benzene, toluene, and xylene (BTX), are air pollutants responsible for many civilizational diseases because of its carcinogenic and mutagenic properties. Concentration of those substances can be even few times higher in micro atmosphere of vehicle cabin than in other indoor atmospheres [1]. The aim of the scientific cooperation between Dr. Schneider Automotive Polska and the Wroclaw University of Science and Technology (WUST) is research on innovative (international range), product development – photocatalytic reactor characterized by Volatile Organic Compounds, especially BTX removal properties. The BTX reduction effectiveness, caused by photocatalytic reactor application in vehicle ventilation system, was subjected to in-depth analysis. The results showed difference on not only maximal benzene, toluene, and xylene reduction (separately) but also in the pattern of response surface. In some tested parameters, the hazardous compounds (as a BTX sum) were reduced for almost 70%. The photocatalytic reactor seems to be prospective solution for air quality improvement in any vehicle cabin.

Opis:
Passive autocatalytic recombiners (PAR) is the only used method for hydrogen removal from the containment buildings in modern nuclear reactors. Numerical models of such devices, based on the CFD approach, are the subject of this paper. The models may be coupled with two types of computer codes: the lumped parameter codes, and the computational fluid dynamics codes. This work deals with 2D numerical model of PAR and its validation. Gaseous hydrogen may be generated in water nuclear reactor systems in a course of a severe accident with core overheating. Therefore, a risk of its uncontrolled combustion appears which may be destructive to the containment structure.

Opis:
This paper studies the temperature dependences (2 < T < 300 K) of the DC conductivity σ(T) for the $(Co_{0.45}Fe_{0.45}Zr_{0.10})_x(Al_2O_3)_{1-x}$ nanocomposites (30 < x < 65 at.%) sputtered in Ar + $O_2$ atmosphere. It is shown that at temperatures lower than 100-150 K dependences of DC conductance on temperature for all the studied samples are due to the Shklovski-Efros variable range hopping mechanism. It was also observed that σ(x,T) dependences can be attributed to the formation of FeCo-based oxide "shells" around metallic alloy nanoparticles due to incorporation of oxygen in the vacuum chamber during the deposition procedure.

Opis:
Celem pracy jest przedstawienie możliwości programu komputerowego WIN-ESTIMATE, stworzonego w 1984 r. przez Keichi Maruyamę – ordynatora oddziału chirurgii w Narodowym Szpitalu Onkologicznym w Tokio, a następnie zmodyfikowanego i przystosowanego do środowiska Windows przez zespół Rüdigera Siewerta z Kliniki Chirurgii Uniwersytetu Technicznego w Monachium. Program ten w obecnej wersji 2.5 szacuje przedoperacyjną obecność przerzutów w węzłach chłonnych u poszczególnych chorych poprzez porównanie ich danych z informacjami zawartymi w bazie danych pacjentów leczonych w latach 1969-1989. W analizie retrospektywnej sprawdzono zastosowanie programu Maruyamy w polskim ośrodku chirurgicznym. Badaniami objęto 40 chorych na raka żołądka, w tym 9 kobiet i 31 mężczyzn. Wszyscy pacjenci przebyli resekcję żołądka z limfadenektomią w ówczesnej II Katedrze i Klinice Chirurgii Ogólnej Akademii Medycznej w Lublinie, a całość danych klinicznych i patologicznych wprowadzano do programu i poddano analizie statystycznej z zastosowaniem nieparametrycznego testu Kruskala- Wallisa. Analiza wykazała, że program ten umożliwia niezależnie od przyjętych standardów dokładną i indywidualną ocenę rozległości zabiegu operacyjnego.
The aim of the study is evaluation of possibilities of WINESTIMATE computer program application, created in 1984 by Keichi Maruyama, the head of the Surgery Department in National Cancer Center in Tokyo, and subsequently modified and Windows-adapted by Rüdiger Siewert’s team of the Surgery Department, Technical University of Munich. The upgraded 2.5 version of the program estimates preoperatively the presence of lymph nodes metastases in patients and compares data with records of patients who underwent surgical treatment between 1969 and 1989. Presented retrospective analysis shows how the application of Maruyama program complies with the situation of surgery centres in Poland. Forty gastric cancer patients (31 men and 9 women) were included in the study. All patients underwent stomach resection with lymphadenectomy in 2nd Department of General Surgery, Medical University of Lublin. The clinical and pathological data were introduced into the program. Kruskal and Wallis’ non-parametric test was used in the statistic analysis. Results evaluation proved that regardless of the adopted standards, computer program allows a thorough and individual estimation of the extent of the necessary surgical treatment.

Opis:
Introduction. Minimally invasive techniques in colorectal surgery have become increasingly popular and are considered a standard of care in most surgical cenres. Locating the tumour during laparoscopic procedure can be technically challenging. Incorrect localization of the primary lesion may lead to a non-radical resection margin. The technique of endoscopic tattooing (ET) prior to surgery or endoscopic treatment is considered a useful tool. Various dyes can be used for this purpose, such as: Indian ink, methylene blue, indigocarmine, toluidine blue, isosulfan blue, haematoxylin and eosin, indoxin green. This procedure is recommended by international scientific societies (ASGE and ESGE). Objective. The purpose of the study is to review the current literature on the use of ET in large intestine tumour lesions. Materials and method. A MEDLINE literature search of English language articles addressing the use of ET to enable intraoperative tumour localization in colorectal surgery was performed to evaluate and summarize the feasibility of this technique. Results. The use of ET enables the easy and safe localization of colorectal tumurs during minimally invasive colorectal procedures. The percentage of complications is insignificant. Conclusions. The available literature proves the safety and benefits of using the ET prior to surgical or endoscopic treatment. ASGE and ESGE recommend the use of ET in marking tumours before surgical treatment, and the area after endoscopic resection for further evaluation.

Opis:
In this work anisotropic magnetoresistance in nanogranular Ni films and Ni nanorods on Si(100) wafer substrates was studied in wide ranges of temperature and magnetic field. To produce Ni films and nanorods we used electrochemical deposition of Ni clusters either directly on the Si substrate or into pores in SiO₂ layer on the Si substrate. To produce mesopores in SiO₂ layer, SiO₂/Si template was irradiated by a scanned beam of swift heavy 350 MeV ¹⁹⁷Au²⁶⁺ ions with a fluence of 5×10⁸ cm¯² and then chemically etched in diluted hydrofluoric acid. Pores, randomly distributed in the template have diameters of 100-250 nm and heights about 400-500 nm. Comparison of temperature dependences of resistance and magnetoresistance in Ni films and n-Si/SiO₂/Ni structures with Ni nanorods showed that they are strongly dependent on orientation of magnetic field and current vectors relative to each other and the plane of Si substrate. Moreover, magnetoresistance values in n-Si/SiO₂/Ni nanostructures can be controlled not only by electric field applied along Si substrate but also by additionally applied transversal bias voltage.
