Opis:: Introduction: The mycological literature currently devotes much attention to the issue of reduced fungal susceptibility to commonly used antifungal drugs. Purpose: To assess drug susceptibility of Candida strains isolated from samples collected from the surfaces of mobile phones and the hands of their owners. A total of 175 mobile telephones belonging to students and lecturers of the Medical University of Bialystok and University Hospital personnel as well as 175 hands of these phone owners were included in the mycological evaluation. Results: The rate of Candida contamination of personal mobile phones was more than 70.0%. C. glabrata strains were primarily isolated from the collected material (89.1% - hands; 74.9% - mobile phones). C. albicans strains showed susceptibility to most antimycotics, with the highest susceptibility to 5-fluorocytosine, and the lowest to fluconazole. C. glabrata showed the lowest susceptibility to fluconazole and miconazole, and the highest to ketoconazole. C. krusei were relatively very sensitive to antibiotics, except for fluconazole. None of the isolated strains showed resistance to more than three types of drugs. Conclusion: This study demonstrated that mobile phones are potentially vehicles for pathogenic Candida strains in a university and hospital settings.

Tematy:: isolated speech recognition

resources estimation
Opis:: In recent years, speech recognition functionality is increasingly being added in embedded devices. Because of limited resources in these devices, there is a need to assess whether the defined speech recognition system is feasible within given constraints, as well as estimating how many resources the system needs. In this paper, an attempt has been taken to define a technique for estimating hardware resources usage in the speech recognition task. To determine the parameters and their dependencies in this task, the two systems were tested. The first system utilized Dynamic Time Warping pattern matching technique, the second used Hidden Markov Models. For each case, the measurement of recognition rate and time, vocabulary database size and learning time has been performed. Obtained results have been exploited to define linear and polynomial regression models, and finally, an estimation algorithm has been developed using these models. After testing proposed approach, it was observed that even low-end mobile phones have sufficient hardware resources for realisation of isolated speech recognition system.

sphenoid fungal sinusitis
Opis:: Invasive fungal sphenoid sinusitis is a rare and potential life threating disease. An incidence rate of fungal sphenoiditis among patients with isolated sphenoid disease varies from 4.5% to 26.8%. Generally the symptoms of sphenoid sinusitis are non-specific and include headaches, visual disorder, post nasal drip, nasal obstruction and paralysis or paresis of single or multiplicitous cranial nerves. In this study, a case of isolated invasive fungal left sphenoiditis in immunocompetent 56-year-old woman is described. The first sinus computed tomography (CT) examination revealed complete opacification of the left sphenoid sinus, she second CT scans showed also erosions of the sphenoid sinus bony walls. Endoscopic sinus surgery was performed and intraoperatively fixed and dilated left pupil was observed thus surgery team decided to finish an operation immediately. Ophthalmologist diagnosed the left oculomotor nerve paresis. Pathologic analysis demonstrated fungal hyphae morphologically identical to Aspergillus spp. Due to suspicion of cerebrospinal fluid (CSF) leak, increasing pneumocephalus and manifestation of mental changes in our subject, endoscopic reoperation with CFS fistula closure was done nine days after the first operation. The patient was treated with intravenous voriconazole and ceftriaxone for one month, and after discharge with itraconazole for 3 months. The full recovery of the left oculomotor nerve function ensued 4 months after surgery and no signs of recurrence of the fungal disease were present up to date.
Inwazyjne grzybicze zapalenie zatoki klinowej jest rzadką ale potencjalnie zagrażającą życiu chorobą. Częstość występowania grzybiczego zapalenia zatok wśród pacjentów z izolowanym zapaleniem zatoki klinowej wynosi 4.5% do 26.8%. Najczęściej objawy zapalenia zatok klinowych są niespecyficzne i obejmują bóle głowy, zaburzenia widzenia, spływanie po tylnej ścianie gardła, niedrożność nosa oraz pojedyncze lub mnogie porażenie bądź niedowład nerwów czaszkowych. W tej pracy opisany został przypadek izolowanego, inwazyjnego zapalenia lewej zatoki klinowej u 56-letniej pacjentki bez zaburzeń odporności. Pierwsze badanie tomografii komputerowej zatok (TK) ujawniło całkowite zacienienie lewej zatoki klinowej, a drugie badanie TK wykazało również erozję ścian zatoki klinowej. Przeprowadzono endoskopowy zabieg zatok i śródoperacyjnie zaobserwowano nieruchomą i poszerzoną lewą źrenicę, z tego powodu zespół chirurgiczny zdecydował o natychmiastowym przerwaniu zabiegu. Okulista rozpoznał niedowład lewego nerwu okoruchowego. Badanie histopatologiczne wykazało obecność strzępków grzybni, podobnych do Aspergillus spp. Ze względu na podejrzenie wycieku płynu mózgowo-rdzeniowego (PMR), nasilenie odmy śródczaszkowej i pojawienie się zmian psychicznych u naszej pacjentki, endoskopowa reoperacja z zamknięciem przetoki PMR została wykonana dziewięć dni po pierwszej operacji. Pacjentka była leczona dożylnie worykonazolem i ceftriaksonem przez miesiąc, a po wypisie do domu - itrakonazolem przez 3 miesiące. Pełny powrót funkcji lewego nerwu okoruchowego nastąpił po 4 miesiącach od operacji i do tej pory pacjentka nie ma objawów nawrotu choroby grzybiczej.

Opis:: Stratigraphic slope wetlands result from discharging ground water and can be found anywhere in dissected landscapes. Both seeps and fens are stratigraphic slope wetlands and the difference between the two in the Midwestern USA is not always clearly defined. Geomorphic features of 30 stratigraphic slope wetlands in Muscatine County, Iowa were measured using global positioning system and geographic information system technology. One-way ANOVA was used to test the hypotheses that the area, elevation, and/or slope would be significantly different between seeps and fens of differing parent material. The results suggest that fens and seeps are geomorphically indistinguishable from one another.

Tytuł:: Isomorphism as generalization tool (in combinatorics)
Autorzy:: Krpec, Radek
Powiązania:: https://bibliotekanauki.pl/articles/748914.pdf
Data publikacji:: 2016
Wydawca:: Polskie Towarzystwo Matematyczne
Tematy:: generic model theory

isomorphism
generalization
Opis:: The article deals with constructing the discovery of the number of combinations. It stems from the approach of genetic constructivism, which works with the generic model theory, and its research goal was to develop the stages of isolated models, particularly using the phenomenon of isomorphism. Children aged 11–13 participated in the experiment during their mathematics club, in which they worked in groups at first and together at the blackboard afterwards. The results come from analyzing the experiment protocol and a video recording of part of the experiment. In this study, the authors focus primarily on a detailed analysis of individual sub-phases of isolated models under the generic model theory. The experiment highlights the importance of isomorphism as a generalization tool. The authors have identified the obstacles on the way to advanced sub-phases of isolated models. Another contribution is the division of the fourth sub-phase into two separate sub-phases, which has been achieved using the method of atomic analysis.

Tematy:: damage detection

Opis:: In this paper, experimental studies are performed and presented to verify the capability of the adaptive extended Kalman filter (AEKF) approach for identifying and tracking damages in nonlinear structures. A base-isolated building model consisting of a scaled building model mounted on a rubber-bearing isolation system has been tested experimentally in the laboratory. The non-linear behavior of the base isolators is represented by the Bouc-Wen model. To simulate the structural damages during the test, an innovative device, referred to as the stiffness element device (SED), is proposed to reduce the stiffness of the upper storey of the structure. Various damage scenarios have been simulated and tested. The measured acceleration response data and the AEKF approach are used to track the variation of the stiffness during the test. The tracking results for the stiffness variations correlate well with that of the referenced values. It is concluded that the AEKF approach is capable of tracking the variation of structural parameters leading to the detection of damages in nonlinear structures.

Opis:: In this study, the inverter in a microgrid was adjusted by the particle swarm optimization (PSO) based coordinated control strategy to ensure the stability of the isolated island operation. The simulation results showed that the voltage at the inverter port reduced instantaneously, and the voltage unbalance degree of its port and the port of point of common coupling (PCC) exceeded the normal standard when the microgrid entered the isolated island mode. After using the coordinated control strategy, the voltage rapidly recovered, and the voltage unbalance degree rapidly reduced to the normal level. The coordinated control strategy is better than the normal control strategy.
