The Medical Simulation Center at the Medical University of Białystok was created as part of a broader project. Throughout Poland there are 12 such centers, and each with a somewhat different concept. The common denominator is that they help medical, nursing, and obstetrics students test their knowledge and skills in practice. The Medical Simulation Center in Białystok boasts a sizeable set of simulation facilities, including an operating room, ambulance, emergency ward, labor ward, and nurse’s station. The technicians devise scenarios for students to enable them to practice reacting to specific cases. All the facilities are equipped with state-of-the-art audio-video equipment to record lessons for later review and analysis.

Simulation-based models standing in for the real world are unfettered by any biological, emotional, historical, logical, or practical limitations.

Dr. Takao Ishikawa from the University of Warsaw talks about why perhaps not all scientists should aim to become professors, and explains what we can learn from yeast proteins.

This article presents a sequential model of the heating-remelting-cooling of steel samples based on the finite element method (FEM) and the smoothed particle hydrodynamics (SPH). The numerical implementation of the developed solution was completed as part of the original DEFFEM 3D package, being developed for over ten years, and is a dedicated tool to aid physical simulations performed with modern Gleeble thermo-mechanical simulators. Using the developed DEFFEM 3D software to aid physical simulations allows the number of costly tests to be minimized, and additional process information to be obtained, e.g. achieved local cooling rates at any point in the sample tested volume, or characteristics of temperature changes. The study was complemented by examples of simulation and experimental test results, indicating that the adopted model assumptions were correct. The developed solution is the basis for the development of DEFFEM 3D software aimed at developing a comprehensive numerical model allows the simulation of deformation of steel in semi solid state.

The hulls of naval ships are exposed to forces and moments coming from internal and external sources. Usually, these are interactions that can be described mathematically by harmonic and polyharmonic functions. The shock of UNDEX type (underwater explosion) works completely differently and its time waveform is difficult to describe with mathematical functions as pressure vs. time. The paper presents a simplification of physical and mathematical models of 1-D kickoff pressure whose aim is performance the simulation of the external force of the detonation wave. The proposed models were verified and tuned on naval, sea trials. The main goals of the proposed models are to perform simulation calculations of the detonation pressure for different explosion charge weights from different distances of the UNDEX epicentre for the design process of machine foundation. The effects of pressure are transformed as impulses exposed on shock absorber mounted at light shock machine.

Antarctica is a land of surprises. How low are the lowest temperatures ever recorded there? Is there life at –50°C? Is there anywhere on the continent tourists can actually enjoy swimming?

Safe mine operations and optimal economical decision making in the context of lignite resources require an adequate level of knowledge about the spatial distribution of critical attributes in terms of geometry and quality in the deposit. Therefore, ore body models are generated using different approaches in geostatistics, depending on the problem to be solved. In this article the analysis of geostatistical methods used for deposits modeling has been presented. Based on exploration data concerning caloric value Q, models of one exemplary lignite deposit has been made. Two models of deposit were prepared using two different methods: ordinary kriging (OK) and sequential Gaussian conditional simulation (SGSIM). Different models of the same deposit were analyzed and compared with source data using criterion of fidelity to statistical attributes like: mean value, variance, statistical distribution. Models, which have been created based on exploration data, were compared with in-situ data gained from survey activities in the exploitation process. As a result of comparison correlation factor and measures of deviations were computed: average relative error, absolute relative error. Models were compared with in situ data, considering statistical features and local variability as well. In conclusion, the study gives valuable information into the benefits of using certain geostatistical approaches for variable tasks and problems in the lignite deposits design process. For the assessment of average values of deposit parameters ordinary kriging provides appropriate effects. Geostatisical simulation (e.g. sequential Gaussian simulation - SGSIM) provides much more relevant information for tasks connected to probability (or risk) of defined threshold exceedences than ordinary kriging. Models made with simulation method are characterized by high fidelity of spatial distribution in comparison to source data.

Optical coherence tomography (OCT) – a kind of optical counterpart of ultrasound imaging – is continually being improved as image contrast boosting techniques are developed.

Prof. Przemysław Perlikowski, a mechanical engineer, and his wife Asst. Prof. Renata Perlikowska, who studies opioid peptides used in medicine, discuss the challenges of research work and life.

Weather forecasting requires knowledge of the laws of atmospheric movement. Apart from classic fluid mechanics, we must consider the rotational motion of our planet, the differential heating of its surface through the absorption of solar radiation, as well as water evaporation and condensation processes.

Polish-Belgian relations are not just about economics or joint membership in European institutions. Rather, they are a story of centuries-old friendship between two nations that cherish freedom. This was the leitmotif of a conference held on the occasion of the 100th anniversary of the establishment of diplomatic relations between the two countries. The conference took place at the headquarters of the Belgian Ambassador in Poland on 11 April 2019, with Polish Senator Anna Maria Anders in attendance.

They are unfairly regarded as junk protein, but the truth is they have not been properly studied due to a lack of suitable tools. So how much do we really know about non-globular proteins?
