    Opis:
    Background: Chronic rhinosinusitis (CRS) is one of the most common health complaints affecting 15% of the world’s population. Recent reports confirm the participation of sensory organs in the defense process against pathogenic microorganisms. The bitter taste receptor TAS2R38 is described to play a role in the upper airway defense system. Purpose: The purpose of this study was to assess the function of the bitter taste receptor in correlation with the severity of CRS, sensory organ disorders and allergic reaction. Material and method: The study contained 100 patients undergoing nasal surgery, divided into two groups: CRS with and without nasal polyps. The control group consisted of patients undergoing septoplasty after excluding rhinosinusitis. Sinus mucosa samples obtained during surgery were used to assess TAS2R38 expression using immunohistochemistry. The IgE level was indicated from blood samples collected from patients. The Sniffin’ Sticks Test was performed. Results: CRS patients had higher expression of TAS2R38 receptor compared to controls (p = 0.0175). A statistically significantly higher TAS2R38 H-score in nasal mucosa was found among patients with a higher inflammation process in CT scan (p = 0.001), higher IgE level (p = 0,04) and an abnormal result of the Sniffin’ Sticks Test. Conclusions: Patients with CRS had significant TAS2R38 receptor overexpression correlating with the severity of inflammatory changes in CT scans, abnormal perception of smells and higher IgE level. A cumulative impact was found between the inflammatory changes, smell disfunction and the severity of subjective symptoms of CRS (according to EPOS) and the intensity of cell staining (index H-score).

    Opis:
    Conditions for the indirect transesophageal atrial stimulation (TAS), useful for cardiac diagnosis and treatment, are optimized both by way of clinical experiment and a computer modelling. The paper demonstrates the results of comparison of electric current density, obtained on the surface of the left atrium during computer modelling, with the results of our own experiments. An evaluation was made with the use of spiral CT scanning of the distance between the esophagus and the posterior wall of the left atrium. The average distance in the tested group of 27 subjects was 4.7 ±σ = 1.1 mm. During transesophageal stimulation, we have determined the average excitation threshold of the left atrium, obtaining the value 5.5 ±σ = 1.8 mA in the examined group of 27 patients. The calculated average current density on the surface of left atrium for the selective electrode with point poles used in the experiment amounted to 39.6 μA/mm2. Electric current densities obtained by other researchers by means of computer modelling for omnidirectional and selective ring electrodes turned out to be much lower after adjustment to similar conditions, which was the result of electrically active larger sizes surfaces of the poles of electrodes used in the modelling.

    Opis:
    In recent years, the main macroeconomic problem of Turkey is current deficits. In order to realize sustainable growth, the balance of payment should be kept under control. This control system is directly depends on minimization of current deficits. One of the main reasons of Turkey’s current account deficits is energy imports. By applying the Johansen co-integrated analysis, this paper aims to identify the relationship between energy consumption and economic growth by using the data set between the years 1984–2012 with reference to VAR (Vector Auto Regression). Furthermore, unit root test was applied to the data which is the traditional unit root tests ADF (Augmented Dickey Fuller), PP (Phillip–Perron) and KPSS (Kwiatkowski–Phillips–Schmidt–Shin) and taking into account the structural break test was performed Zivot–Andrews. In addition to examining the long-term relationship between the two variables, taking into account the structural break in the cointegration test Engle–Granger and taking into account the structural break Hatemi-J cointegration test were applied. According to the results of the analysis, we reached that there is a relationship between energy consumption and economic growth.

    Opis:
    In this study, the effects of perlite addition on mechanical properties and wear resistance of alumina ceramics were investigated. Alumina powders including perlite 5%, 10%, 15%, 20% and perlite free were prepared. These powders were shaped as rectangular by using uniaxial pressing system under the load of 100 MPa. The samples were sintered at 1400°C-1550C for 2 h and were subjected to some mechanical tests such as hardness and fracture toughness. X-ray diffraction analysis was employed to determine the crystalline phases. Bulk densities of the samples were measured. In addition, erosive wear test was performed to investigate the erosive wear resistance of the samples. The wear test results were presented depending on different sliding speed and sintering temperature. These results showed that perlite addition has a positive effect on erosive wear resistance of the alumina ceramics, generally.

    The House of Wisdom (Bayt al-Hikmah) was built first as a library where the books on the sciences of the Ancients were kept. Under the sponsorship of the Caliph Al-Ma'mun (813-833), it developed into a scientific institute where the books on Ancient Greek philosophy were translated into Arabic. The Caliph acquired many Greek manuscripts and generously supported the translation activities in the House. By the end of the century, Arabic translation of the major works of the Greek philosophy and science had been completed. Thus, the Caliph and his House paved the way for the rise and flourish of Islamic philosophy and science.

    Opis:
    A metal-insulator transition, Mott transition, in layered materials 1T-TaS$\text{}_{x}$Se$\text{}_{2-x}$ was investigated by cryogenic scanning tunneling microscopy/ spectroscopy. At 77 K, tunneling spectra in the insulating phase showed a conduction band with almost half filling, which becomes narrower as x decreases. Around the transition point x≈1.4 at 77 K, we observed a sign of gap opening without an overshooting peak at zero bias, supporting the Mott localization picture in which a carrier number vanishes at the transition point. From the site-specified scanning tunneling spectroscopy measurements, furthermore, electrons were found to localize at the charge density wave crest positions. In 1T-TaS$\text{}_{2}$, we have also found that both metallic and insulating phases coexist in a nanometer scale just above the transition temperature, 180 K. >From the minimum size of the insulating region, the coherence length of Mott insulating state was evaluated to be≈5 nm.

    Purpose: This paper aims to present a fresh idea on how to model and examine the level of sustainable competitive advantage (SCA) with and without knowledge and /technology (K/T) effects in a case company’s operation by taking the manufacturing strategy’s development directions and the efficiency of resource allocation among its attributes into consideration. Design/Methodology/approach: In this paper, questionnaires are filled by two different managerial groups, company’s management team (G1) and company’s global directors (G2). The analyses based on G1, G2 and G1-G2 (mixed results) are performed and examined as well as the effect of knowledge and /technology rankings to observe the differences on how they effect on company’s operations strategy and what kind of strategy type that decision makers might follow. Besides, the effects of knowledge/technology rankings on SCA risk levels are examined on different case companies to perceive the similarities and differences with our case company. In this case study, the objectives are achieved based on several methodologies: manufacturing strategy index (MSI) [1] and sense and respond (S&R) methodology [2]. Findings: The achieved results through the model are found to be promising corresponding to the feedback from the respondents. Research limitations/implications: The model is applied only in a big sized B2B global company that produces power electronics products. Therefore, further tests need to be applied to the model in case of multiple companies from different sizes and areas to figure out the best formula in case of validation of strategic direction (MAPE, RSME or MAD). Practical implications: As a result of its wide applicability and its ease in arrangement the model has an enormous potential for strategic decision-making process and strategic analysis. Originality/Value:The model can provide a more dependable possibility of sustainable improvement to the corporate operational excellence and strategy.

    Opis:
    W artykule omówiono rozwiązania techniczne związane z projektem i budową budynku biurowego w Gdańsku. Przedstawiono problemy związane z głębokim posadowieniem na terenie zagrożonym podtopieniami, wymagającym wykonania poziomej przesłony przeciwfiltracyjnej połączonej z obudową ścianami szczelinowymi. Opisano sposób modularnego kształtowania konstrukcji z betonu architektonicznego i dochodzenia do efektu metodą prób na budynku wzorcowym (mock-up). W rozwiązaniach projektowych znalazły się nietypowe stropy monolityczne z zatopionym układem chłodzącym BKT i wbudowanymi profilami stalowymi dla podwieszenia oświetlenia oraz dach szedowy, indywidualizujący charakter budynku.
    In this paper, technical solutions, connected with the project and construction of the office building in Gdansk, have been discussed. Solutions and problems of waterproof barrier (horizontal jet-grouting diaphragm connected with slurry walls), required due to the deep foundation in the flood danger area, have been presented. Modular shaping of the RC structure of architectural concrete and testing the final effects on mock-up, have been described. In the design solutions there have been developed: non typical floor slabs with embedded cooling system BKT and build in steel profiles (due to suspended lighting) as well as the roof folded plate structure, which distinguishes the building form.

    Opis:
    This paper presents our research and development work on new circuits and topologies based on Magnetic RAM for use as configuration memory elements of reconfigurable arrays. MRAM provides non volatility with cell areas and with access speeds comparable to those of SRAM and with lower process complexity than FLASH memories. The new memory cells take advantage of the Thermal Assisted Switching (TAS) writing technique to solve the drawbacks of the more common Field Induced Magnetic Switching writing technique. The CMOS circuit structures to implement the main components for reading and writing the MTJ cells have been developed, characterized and evaluated. A scaled down prototype of a coarse grain reconfigurable array that employs the TAS-MRAM elements as configuration memory has been designed and electrically simulated pre- and post- layout. The results obtained for all the circuit elements, namely the storage cells and the current generators, indicate that the new configuration memory cells can provide a very promising technological solution for run-time reconfigurable hardware devices. The prototype has been manufactured using a standard process 0.35μm 4-Metal CMOS process technology and should be under test in the foreseeable future.
