Opis:
Separation of particles from gas stream is of great importance in many areas of human life. Air filtering materials have wide applications. They are used inter alia in ventilation and air conditioning systems, in cars to reduce emission from diesel engines, in the device of everyday use (e.g. vacuum cleaner), as a personal protective equipment for example to avoid inhalation hazardous dust from industrial processes. Small airborne particles can cause a variety problems for human health. Long exposure to particles of submicron- and nano-sized has been related to higher death rates due to lung cancer and cardiopulmonary illness. The main object of this study was to investigate filtration efficiency of oil nanodroplets (DEHS di-ethylhexyl sebacate) and salt nanoparticles (KCl) from air using fibrous polypropylene media made by melt-blown technique. Fibrous filters are relatively inexpensive to fabricate and what is the most important they are high efficient with simultaneous low flow resistance. Three types of non-wovens having various morphology with different average fiber diameter were tested. The tests show that both KCl solid nanoparticles and DEHS nano oil-mist can be efficiently separate from the air using melt-blown fibrous materials. Moreover these filters have been also electrically charged by corona discharge. The filtration efficiency of charged filters (electrets) was compared with efficiency of uncharged (mechanicals) samples. Results showed significant increase in filtration efficiency for the filters with electric charge compared with uncharged ones.

Opis:
Celem badań było zmodyfikowanie włókien filtrów polipropylenowych prowadzące do zmiany ich zwilżalności oraz zwiększenia stopnia rozwinięcia powierzchni, aby podnieść efektywność usuwania olejowych nanokropel z powietrza. Wykorzystano włókninę o średniej średnicy włókien równej 11,1 μm, grubości 2,7 mm i gęstości upakowania 7,2%, wytworzoną metodą rozdmuchu pneumotermicznego. Najpierw poddano ją wyładowaniu plazmowemu, a następnie nanoszono dwa rodzaje nanocząstek krzemionki Orisil 200 oraz Ludox SK. Wykazano, iż zastosowane metody prowadzą do zwiększenia skuteczności separacji z powietrza nanokropel mgły olejowej.
The study results of modification of polypropylene filter fibers leading to a change of their wettability and increase of surface development degree to improve the efficiency of nanoparticles’ removal from air are presented. Non-woven fabric of average fiber diameter equal to 11.1 microns, thickness of 2.7 mm and packing density of 7.2% prepared by the melt-blown method was used. First, material was treated by plasma discharge and then two kinds of silica nanoparticles Orisil 200 and Ludox SK were applied. It was proven that those methods led to more effective separation of oil nanodroplets from air.

Opis:
Filtration of liquid aerosol (mist) is one of the most important challenges in many branches of chemical industry. One of the possible ways of filtering materials improvement is modification with aerogels. In this study aerogels based on methytrimethoxysilane (MTMS) which exhibit superhydrophobic, superoleophilic and sorptive (thanks to high porosity) properties were used. Modified filtering materials improve the general retention and fractional efficiency o f oil mist separation in micro- and nanoscale. Although the pressure drop during the filtration on modified filters has been higher, the presented results seem to be promising.
Filtracja aerozoli olejowych (mgły) jest jednym z wyzwań spotykanych w wielu gałęziach przemysłu chemicznego. Jedną z możliwych dróg poprawy właściwości włóknin filtracyjnych jest modyfikacja aerożelem. W niniejszej pracy został wykorzystany aerożel oparty na metyl-trimetoksysilanie (MTMS), który posiada właściwości hydrofobowe, olejofilowe i sorpcyjne względem olei (dzięki dużej porowatości). Modyfikacja włókniny dała poprawę wyników retencji oraz efektywności separacji mgły olejowej w skali mikro i nano. Pomimo wzrostu spadku ciśnienia na filtrach modyfikowanych, uzyskane rezultaty są obiecujące.

Opis:
Wytwarzanie elementów na obrabiarkach sterowanych numerycznie jest techniką bardzo prężnie rozwijającą się i wykorzystywaną do produkcji różnych komponentów w wielu gałęziach przemysłu. Produkowane współcześnie obrabiarki charakteryzują się konstrukcją umożliwiającą uzyskanie wysokiej dokładności geometrycznej maszyny. Niestety najlepiej skonstruowana i wykonana obrabiarka z powodu zmiennego środowiska pracy lub zużycia elementów współpracujących, często nie jest w stania stawić czoła wysokim wymaganiom dokładnościowym produkowanych elementów. W artykule zaprezentowana została metodyka off-line korekcji błędów obróbkowych Opracowana metoda korekcji pozwala na wykonanie komponentów z większą dokładnością niż w przypadku tradycyjnego podejścia.
The manufacture of components on numerically controlled machines is very rapidly developing technique and it is used for production of various components in many industrial sectors. Currently produced machine tools are characterized by construction that allow to achieve high geometrical accuracy. Unfortunately, best designed and constructed machine tool in addition to the variable work environment or wear of associated components, is unable to face the above-mentioned requirements. In this paper was presented off-line correction of machining errors methodology. The elaborated correction method allows to part manufacture with greater accuracy than in traditional approaches.

Opis:
The paper is devoted to topic related with machining error correction for objects bounded by curvilinear surfaces manufactured on numerically controlled milling machine. Currently it is realized by two techniques. The first of them is called on-line and requires continuous correction of toolpath during the machining process. This approach requires expanded adaptive control systems. The second method called off-line is based on correction of machining control system outside the machine (on the basis of control measurement results). This paper shows methodology of machining shape error correction with off-line technique (with no constant and direct connection to CNC machine tool). This method is based on usage of CAD/CAM systems, numerically controlled milling machine and coordinate measuring machine. Manner of procedure proposed in this paper was verified on the example of ruled surface profile described with NURBS technique. Realization of this proposed methodology of machining error correction has shown significant accuracy correction of manufactured element.

Opis:
Ligament reconstruction is one of the surgical methods for treatment of anterior cruciate ligament injury. The main purpose of rehabilitation after surgical ligament reconstruction is to obtain maximal efficiency of knee joint, their stability and appropriate lower limbs encumbrance. Static posturography is one of the control, rehabilitative and diagnostic tools in such treatment. The purpose of the study was to evaluate the posture stability differences between healthy people and patients after anterior cruciate ligament reconstruction. The centre of pressure sway was registered using the standard posturography platform (Pro-med). During the test, the subject stood freely with eyes open and closed. In order to determine the stability of the subject, the average velocity of the centre of pressure sway, and the average accretion rate of surface area encircled by centre of pressure, a mean radius of centre of pressure and amount of its displacement were calculated. Parameters measured for the eyes closed posture were significantly greater for people after anterior cruciate ligament reconstruction, while differences between groups for eyes open test were statistically insignificant. This indicates impairment of the somatosensoric posture control system. It should be noted that selected stability indicators: an average velocity of the centre of pressure sway, its anterior-posterior and mediolateral components, a mean radius of centre of pressure and a mean accretion rate of surface area encircled by centre of pressure varied in both groups.

Opis:
It is essential to know the movement of droplets in time and space (i.e. flux) when measuring and/or predicting spray drift in agricultural application. A study was performed to assess the flux measurements of a phase Doppler system against a standard monofilament system in a wind tunnel. The primary objectives of the study were to compare flux from a new phase Doppler system against 1.7 mm cotton and 2.0 mm nylon strings at varying wind speeds (1.4, 4.2, 8.3, 12.5, and 16.7 m ⋅ s–1) and spray exposures times (5, 10, 15, 30, and 60 s) with an overarching hypothesis that the active, phase Doppler is able to accurately measure the flux regardless of exposure and spray mass whereas the static string samplers are limited to a maximum retention. The phase Doppler did measure linearly as expected, however strings did not reach a point in which they loss mass; conversely, they appeared to overload with saturation. These findings are believed to be among many variables which influence the variability of previous mass balance studies.

Opis:
Complex perovskite oxides exhibit a rich spectrum of functional responses such as: superconductivity, magnetism etc. Combination of different oxides in multilayered structures increases the number of physical responses. Heterogeneous oxide structures represent a new class of nanostructures. They consist of ferromagnetic $La_{0.67}Sr_{0.33}MnO_3$ (F-LSMO) manganite and superconducting $YBa_2Cu_3O_7$ (Sc-YBCO) cuprate. The interaction between the two order parameters gives rise to new physical effects. In this review we will discuss various physical effects obtained in the bilayer and trilayer heterostructures. For example, the LSMO/YBCO bilayer structures are used to study the mechanism of magnetic pinning. The other possibility is the fabrication of spin valve-like structures LSMO/YBCO/LSMO. The spin dependent transport in trilayer structure was studied taking into account crossed Andreev reflection and electron co-tunneling processes.

Opis:
Almost entire fleet of steam turbines in Poland was designed between 1950_1980 with the use of the so-called zero-dimensional (0D) calculation tools. For several years, design and modernization of the turbines occur in assistance with the state-of-the-art methods that describe working fluid flow field based on three-dimensional (3D) models and computational fluid dynamics (CFD) codes. This cooperation between 0D and 3D codes requires exchange of overall, integral information such as: power, efficiency, heat and mass fluxes. In consequence the question arises regarding the cohesion of definitions, and particularly regarding the correctness of the definition for internal efficiency of the turbine's stage and the turbine as a whole. In the present paper we formulate basic definitions reason of efficiency that are naturally adapted to the numerical 0D and 3D models. We show that the main reason of differences between the definitions in 0D and 3D is the definition of the theoretical work of the stage lt. In the classical 0D models, mostly employed is the isentropic approach, and hence the isentropic efficiency occurs. Meanwhile, in the increasingly common 3D approach (most likely by CFD), we use more physically correct pathway by subtracting energy loss from the available energy, that leads to the polytropic definition of efficiency. We show an example of computing the efficiency and the 3D losses, denoted with additional subscript CFD, we also discuss benefits of this definition in comparison with the isentropic classical definition in 0D.

Opis:
The paper presents the results of experiments on modification of pure iron by high-intensity nitrogen pulsed-plasma treatment. The duration of nitrogen plasma pulses is approximately 1 mi s, and the energy density amounts to about 5 J/cm2. Such pulses are capable to melt the surface layer of the substrate (1- 2 mi m) and to introduce a significant concentration of nitrogen into the molten layer. Nuclear reaction analysis (NRA), X-ray diffraction (XRD) and conversion electron Mössbauer spectroscopy (CEMS) were used for characterisation of the treated samples. The main results of the data analysis are as follows: it has been stated that such treatment leads to gradual transformation of initial alfa-phase into austenitic gamma structure in which expanded austenite gammaN is present. Treatment with 20 pulses results in almost complete transformation and introduces a retained dose of nitrogen estimated as 5.5 × 1017 N/cm2. The susceptibility for expansion of the lattice transformed to austenite in this way is smaller than in the case when the steel subjected to conventional nitriding is originally of austenite type. The analysis of the ratio of alfa to gammaN as a function of the nitrogen content provides a firm evidence that strong repulsion forces act between the first and the second nearest-neighbour nitrogen atoms in the fcc austenitic structure formed as a result of nitriding of pure iron by intense nitrogen plasma pulses.

Opis:
Thin layers of $MgB_x$ were studied in order to define evolution of superconducting phase after Mg ions implantation into boron substrate. Three fluencies of energies 140, 80, and 40 keV were used to establish proper stoichiometry to synthesize homogeneous $MgB_2$ film. Additionally, the annealing processes were carried out at temperatures 400, 500, and 600°C in a furnace in an atmosphere of flowing $Ar-4%H_2$ gas mixture. The quality of the superconducting material was examined by magnetically modulated microwave absorption, and magnetic and resistivity measurements. The results showed that $T_c$ becomes higher with increasing annealing temperature. However, the fraction of superconducting phase decreases, due to partial evaporation of Mg ions and their deeper migration into boron substrate.

Opis:
A new borehole in Rożce (SW Mazovian Lowland) drilled in 2012, combined with a wide variety of research methods (palaeomagnetism, palynological analysis, studies of plant macroremains and textural features of deposits) shed new light on the age and stratigraphic position of the Early Pleistocene deposits, formerly assigned as the Lower Pleistocene. The study focuses on the deposits from 50.7-104.0 m depth, between glacial till of the Nidanian Glaciation (ca. 0.9 Ma) and the Poznań Clays (ca. 5.322 Ma). The deposits situated directly underneath the till (50.7-60.2 m) are related to the Nidanian Glaciation and show a reversed polarity and correlate with the end of the Matuyama Epoch. The deposits from 60.2-104.0 m depth were accumulated during the Early Pliocene, i.e. approximately 5.332-4.6 million years ago. They appear to correlate with the middle part of the Gilbert Palaeomagnetic Epoch and thus they are considerably older than previously thought. The cored section indicates a stratigraphic gap of about 3.5 Ma from the Lower Pliocene to the first advance of the Scandinavian ice sheets into Poland, which are thought to have occurred in the early Middle Pleistocene. The analysed deposits accumulated under variable climatic conditions showing two periods with significant aridity alternated with two periods of increased humidity. Deposits of the arid periods contain no pollen, butaeolian sand quartz grains are found. During periods of more humid climate the area was covered by various types of mixed forest.

The results of investigation of the MgB$\text{}_{2}$ inter-metallic compound with the use of boron ions implantation and plasma pulse treatment are presented. The samples were characterized by: four-probe electric conductivity measurements, magnetically modulated microwave absorption, and magnetic measurements. For hydrogen and argon pulsed plasma treatment the samples with T$\text{}_{c}$ ranging from 10 K to 32 K were obtained. The superconducting phase does not form a continuous layer since the resistivity does not fall down to zero. Apparently, separate islands of superconducting phase are connected through metallic Mg paths. All samples are still below the percolation threshold.
