Opis:
The main practical problem in the Logistics Department at the company is overstaffing in the unit responsible for the flow of materials. Carried out by the authors of the article, some detailed research on the process analysis in the discussed company indicates that the main cause of such a situation is related to an increase in the amount of transported material and a lack of redesigning the material flow in spite of the increased levels of production and acquisition of new projects. At present, at the company the material is prepared and transported by eleven employees whose work is not standardized and impossible to control. Such a large number of people working at the same time at the warehouse and moving through the transport corridors seriously affects the level of safety in a negative way. Therefore, the authors of the publication have suggested three solutions which involve some logistic changes in the existing process in order to increase safety and to reduce the number of staff involved in the transport.

Opis:
The aim of the article is to present a concept related to the improvement of the logistics process at the company, by the modernization of the main railway siding of the terminal. The paper present the reasons for the decision that was once made in order to obtain the expected advantages after the modernization. The comparison of the incurred expenses and the profits that might be gained in the future allows us to state that the decision about the modernization was the right one. The decision about the modernization also referred to a trend towards an increase in cargo handling operations, which could be observed at the company at that time. The decision about modernization was made when the terminal operated using its full capacities of the railway siding. Therefore, the modernization was necessary in order to meet expectations expressed by the current and potential customers who might appear in the future.

Opis:
Spatial magnetization distribution of cobalt layer is studied by means of three-dimensional micromagnetic simulations in the range of cobalt thickness d from 21 to 249 nm. In this range, a spin-reorientation phase transition occurs, while the cobalt thickness increases, from a state with in-plane magnetization, to a state with out-of-plane components of magnetization. An infinite cobalt layer is modelled by the 750 nm × 750 nm × d structure consisting of cubic cells of size of 3 nm and the periodic boundary conditions. For larger thicknesses, a labyrinth, partially closed, stripe structure has been found.

Opis:
The calculation of the temperature dependence of the domain wall coercivity of ultrathin magnetic films with perpendicular anisotropy is reported. In this case, the magnetization reversal is supposed to occur through domain wall motion. The proposed model takes into account thermal bending fluctuations of the domain wall, which is pinned by crystal defects such as grain boundaries. A fitting procedure, applied to recently published experimental data on the field induced domain wall velocity in Au/Co films, allows us to find out realistic values of the involved parameters.

Opis:
30 keV $Ga^{+}$ irradiation-induced changes of magnetic and magneto-optical properties of sputtered Pt/Co/Pt ultrathin trilayers films have been studied as a function of the ion fluence. Out-of-plane magnetic anisotropy states with enhanced magneto-optical effects were evidenced for specific values of cobalt thickness and irradiation fluence. Results obtained after uniform or quasi-uniform focused ion beam irradiation on either out-of-plane or in-plane magnetized sputtered pristine trilayers are compared. Similar irradiation-induced magnetic changes are evidenced in quasi-uniformly focused ion beam or uniformly irradiated films, grown either by sputtering or molecular beam epitaxy. We discuss on plausible common mechanisms underlying the observed effects.

Opis:
Radiation induced changes in the luminescence spectrum under influence of UV light, γ-rays, electrons and protons for several concentrations of Ce$\text{}^{3+}$ ions as well as Mg$\text{}^{2+}$ ions in yttrium-aluminum garnet crystals were investigated. To irradiate with γ and electron as grown crystals were used while for proton irradiations the crystals were thermally annealed. For small concentrations of cerium ions (≈0.01 at.%) an increase in the luminescence (about 100%) was observed after gamma irradiation with a dose of 10$\text{}^{5}$ Gy. This increase was due to the growth in Ce$\text{}^{3+}$ ions concentration after γ-irradiation (≈50%), due to the Ce$\text{}^{4+}$ → Ce$\text{}^{3+}$ recharging reaction. For highly doped Ce:YAG crystals (0.1 at%, 0.2 at.%) also an increase, but much smaller (4%), for the Mg codoped crystals (0.1 at.%) was observed. After 1 MeV electron irradiation in the over-threshold type interaction a decrease in luminescence is observed due to the domination of the Ce$\text{}^{3+}$ → Ce$\text{}^{4+}$ ionization process. In the case of the proton irradiation, for small fluencies (≈10$\text{}^{13}$ particles/cm$\text{}^{2}$) an increase in luminescence is observed due to the domination of the recharging processes of Ce$\text{}^{4+}$ ions. For larger fluencies (>10$\text{}^{14}$ particles/cm$\text{}^{2}$) a decrease takes place due to a high level of radiation defects.

Opis:
In this paper we report preliminary results of optical studies on Y$\text{}_{3}$Al$\text{}_{5}$O$\text{}_{12}$ (YAG) crystals codoped with Ce and Mg. By using measurements of luminescence, absorption, and luminescence excitation spectra we demonstrate that although the basic features introduced to the YAG host by the Ce-doping remain intact, the Mg-codoping imposes some significant changes on other properties of the material. These changes are potentially important for laser and/or scintillator applications of YAG:Ce and are due, most likely, to modifications of defect populations in the material. We characterize them by using the techniques of thermoluminescence and excited state absorption under excimer laser pumping. These techniques, interestingly, yield results that seem inconsistent. While the thermoluminescence signal of the Mg-doped sample is strongly reduced, suggesting that trap concentrations in the presence of Mg are suppressed, the excited state absorption signal, which we also relate to the traps, is higher. We offer a tentative explanation of this contradiction between the two experiments that involves a massive transfer of electrons from the Mg-related defects to the excited state absorption centers caused by the excimer pump itself.

Opis:
Introduction: Colorectal cancer (CRC) is one of the most common cancers in Poland. The aim of this study was to investigate the clinical significance of absolute monocyte count, neutrophil-to-monocyte ratio (NMR) and monocytetolymphocyte ratio (MLR) in pre- and postoperative blood samples of patients with CRC. Materials and Methods: We retrospectively reviewed medical records of 160 patients diagnosed with CRC who underwent surgery. Blood samples were obtained within 3 days before and after the surgical treatment. Venous blood samples were also obtained from 42 healthy controls. Results: Pre- and postoperative NMR were significantly higher than healthy controls (p<0.0001; p<0.0001). Moreover, MLR in pre-and postoperative blood samples were higher than voluntaries (p<0.001; p<0.001). The area under the ROC curve for pre and postNMR showed that the parameter exhibits strong diagnostic power (1.000). Pre- and postMLR had moderate diagnostic power amount 0.751 and 0.746. There is also correlation between monocyte count in samples obtained before and after surgery and, lymph node metastasis and size of lymph node metastasis in both cases. PreNMR value was significantly associated with venous and lymphatic invasion and the presence of cancer deposits. PostNMR was found to correlate with presence of distant metastasis and cancer cell deposits (R=0.633, p<0.001; R=0.158, p=0.040). Moreover, preMLR value was correlated with only perineural invasion. Conclusions: Analyzed hematologic markers may be useful as simply obtained parameters, next to histopathological examination, that determine a systemic immune response

Opis:
Introduction: Colorectal cancer (CRC) is the third most common cancer worldwide. At every phase of cancer development, the inflammatory process has an important impact. Accurate assessment inflammatory cells in the tumour environment in conjunction with clinico-pathologic features can be a relevant prognostic or predictive parameter. Purpose: To analyse inflammatory cell infiltration in CRC tumour mass and correlate with chosen clinico-pathologic parameters. Materials and methods: The study group consisted of 160 patients (64 women, 96 men) diagnosed with colorectal cancer who underwent surgery. Tissue material obtained from routine histopathological diagnosis was stained with H&E and used to assess the type of inflammatory cells in the invasive front and centre of the tumour. Results were subjected to statistical analysis with the age and gender of patients, tumour localization, tumour growth and size, TNM stage, adenocarcinoma type, fibrosis, necrosis, metastasis and tumour invasion (by the Spearman’s correlation coefficient test). Results: The presence of neutrophils in the invasive front of tumour mass was associated with fibrosis and inflammatory cell infiltration in the invasive front of tumour. Macrophages in the invasive front of tumour were found to correlate with tumour growth (expanding and infiltrate). Macrophages and eosinophils were associated with inflammatory cell infiltration in the invasive front and in the centre of tumour. Conclusions: The type of inflammatory cells in the invasive front or centre of the tumour may be useful to prognoses clinical features of colorectal cancer

The influence of He⁺ (10 keV) ion bombardment on magnetic properties of sputter deposited $Ni_{80}Fe_{20}$/Au/Co/Au layered films was studied. The variable parameters were the thickness of the Co layer or Au spacer and the ion dose. The magnetooptical Kerr measurements were performed on samples with wedge shaped Co or Au layers. With increasing dose of helium ions the following changes in magnetic properties were observed: (i) a decrease in the Co thickness range corresponding to the perpendicular anisotropy, (ii) a decrease in the coercive field $(H_C)$, (iii) an increase in the ferromagnetic coupling between ferromagnetic layers.
