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.

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.

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.

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.

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.

Opis:
Juniperus excelsa s. str. (Greek juniper) in Crimea is a relic species on the limits of its range, and represents the Mediterranean flora in the Sub-Mediterranean part of the peninsula. Its origin and history in this area remains unresolved. We aimed to analyze phylogeny and potential demographic expansion of the juniper in the Crimea as well as to study its morphological differentiation. We analyzed plant material from 59 trees inhabiting eight populations. Genetic variation assessments were based on the four non-coding chloroplast DNA (cpDNA) fragments and the nuclear internal transcribed spacer region ITS1-5,8S-ITS2 (ITS). To examine the morphological differentiation, eight measured/counted traits of cones, seeds, and shoots were chosen and eight ratios were calculated. Morphological parameters were compared using ANOVA, Student’s t test, discrimination analysis and Kruskal-Wallis and U MannWhitney tests. Two cpDNA fragments were polymorphic and, in total, 10 cpDNA haplotypes were found. Haplotype diversity (Hd) ranged from 0.0 to 0.9. Based on both cpDNA and ITS sequences variation, phylogenetic analyses revealed a close relationship of the Crimean junipers to the individuals from other parts of the species range. In general, our molecular results confirmed the low level of genetic differentiation of J. excelsa individuals inhabiting different parts of the species range, likely resulting from a common ancestry. Only slight morphological differences were found between populations with different geographic location or habitat. The analyzes showed the distinctness of the populations from the southern part of the coast. Some unique morphological and molecular features of southern coastal populations imply that they are remnants of Late Pleistocene abundant forests. We suggest that the recent fragmentation of the Juniperus populations in the Crimean Peninsula could have arisen during the Atlantic period of the Holocene.

Opis:
Currently, the distribution system has been adapted to include a variety of Distributed Energy Resources (DERs). Maximum benefits can be extracted from the distribution system with high penetration of DERs by transforming it into a sustainable, isolated microgrid. The key aspects to be addressed for this transformation are the determination of the slack bus and assurance of reliable supply to the prioritized loads even during contingency. This paper explores the possibilities of transforming the existing distribution system into a sustainable isolated net-work by determining the slack bus and the optimal locations and capacity of Distributed Generators (DGs) in the isolated network, taking into account the contingencies due to faults in the network. A combined sensitivity index is formulated to determine the most sensitive buses for DG placement. Further, the reliability based on the loss of load in the isolated system when a fault occurs is evaluated, and the modifications required in for reliability improvement are discussed. The supremacy of the transformed isolated network with distributed generators is comprehended by comparing the results from conventional IEEE 33-bus grid connected test system and modified IEEE 33-bus isolated test system having no interconnection with the main grid.

Opis:
This study investigates how different form-focused instruction (FFI) timing impacts English as a foreign language (EFL) learners’ grammar development. A total of 169 Chinese middle school learners were assigned to four conditions randomly: control, before-isolated FFI, integrated FFI, and after-isolated FFI. The three experimental groups received treatments which combined form and meaning with the English passive voice as the teaching target, but learners’ attention was drawn to the passive voice with different timing. The before-isolated and after-isolated groups received the treatment before and after communicative activities, respectively. For the integrated FFI group, intervention occurred during communicative activities. A picture writing test and a written error correction test were employed to measure students’ performance. The results indicated that the three experimental groups manifested significant improvement. Before-isolated FFI produced the best immediate and delayed effects, and integrated FFI produced better immediate effect than after-isolated FFI, while after-isolated FFI produced better delayed effect than integrated FFI. The findings indicated that pedagogical sequences in FFI are important, and teachers might need to guide adolescent learners to focus on form explicitly before communicative activities.

The presented dynamic model which unites energy indicators of power generating systems and economic indicators of the closed macroeconomic system because price regulation on the power market of Ukraine happens in a statics. That’s why not allowed to perform an assessment of dynamic change of the tariff price of the electric power in the local isolated systems. When abrupt change isolated power generating capacity of the system is changing the tariff price of electricity cannot be taken into account when using static models. An example of the isolated system consisting of the diesel generator and the consumer is reviewed. The model allows to research influence of transition processes of the generator on change of cost indicators of an economic system, and also to estimate the adequate tariff price both for the producer, and for consumers of the electric power. This model is modelled in Matlab.

Opis:
A major problem in isolated-word speech recognition systems is detection of the beginning and ending boundaries of the word. It is an essential of speech recognition algorithms, where signal speech segments should be reliably separated. During speech recognition background noise is also recorded, hence the word isolation is difficult. The parametric representation of the speech must provide enough information to characterize the words and to differentiate between acoustically similar words. In this paper the method of words extraction from human speech will be considered.
