Epoxy Composites with Post-Production Gray Cast-Iron Powders.

Processing of cast-iron castings by machining is associated with a large amount of post-production waste in the form of cast-iron chips, which constitute up to about 5% of the weight of the entire casting. In the case of serial production, this generates large amounts of post-production waste, constituting a constantly growing scale of environmental problems. The aim of this research was to develop a simple and cheap method of utilizing post-production waste of gray cast-iron chips from the machining process for the production of small structural elements of water supply fittings.

(Rathke, 1862) as a vector of potentially pathogenic fungi in aquatic ecosystems.

The aim of the study was to check the integument and alimentary tract of for the occurrence of fungi. Moreover, the mycological purity of water sources from which leeches were collected was analyzed. The potential role of the duck leech in transmitting pathogenic fungi has not been studied until now.

Sucking of human blood by (O. F. Müller, 1846) (Hirudinida: Glossiphoniidae): Case study with notes on body form.

Four events of sucking human blood are described.Human blood was sucked by both adult and juvenile specimens of . .

Dishwashers as an Extreme Environment of Potentially Pathogenic Yeast Species.

The study aimed to compare the yeast species diversity in the specific environment of dishwashers, taking into account the potential risk for users. Yeasts were isolated from ten dishwashers and from tap water supplied to the appliances. Samples were collected for mycological analyses at the beginning of each month, from February to May 2016.

Influence of Elemental Carbon (EC) Coating Covering nc-(Ti,Mo)C Particles on the Microstructure and Properties of Titanium Matrix Composites Prepared by Reactive Spark Plasma Sintering.

This paper describes the microstructure and properties of titanium-based composites obtained as a result of a reactive spark plasma sintering of a mixture of titanium and nanostructured (Ti,Mo)C-type carbide in a carbon shell. Composites with different ceramic addition mass percentage (10 and 20 wt %) were produced. Effect of content of elemental carbon covering nc-(Ti,Mo)C reinforcing phase particles on the microstructure, mechanical, tribological, and corrosion properties of the titanium-based composites was investigated.

Phyllosphere of Submerged Plants in Bathing Lakes as a Reservoir of Fungi-Potential Human Pathogens.

This study analysed whether the littoral zone in the immediate vicinity of bathing sites retains potentially pathogenic yeasts on the phyllosphere surface and to what extent the species composition of microfungi in the phyllosphere and in surface waters is similar. The research was carried out in selected lakes located within the administrative boundaries of the city of Olsztyn, the largest city in the Masurian Lake District (NE Poland). The experiment was conducted in three summer seasons near bathing sites in three lakes, which are the most popular as recreational sites (Lake Kortowskie, Lake Tyrsko, and Lake Skanda).

Potentially pathogenic fungi of the Candida genus isolated from the Łyna River – a 20-year study.

This paper concerns part of a monitoring study and contains the results of 20-year observations on the species diversity and dynamics of the count Candida genus fungi which inhabit surface waters. The research material consisted of water samples collected from the Łyna River, the main river of the Warmińsko-Mazurskie Voivodeship, within the administrative boundaries of the city of Olsztyn. The samples were subjected to routine diagnostic testing applied in hydromycological studies.

Yeasts isolated from frequently in-patients and out-patients.

The paper is a part of a general mycological monitoring study of nosocomial infections. Differences in the species composition and drug resistance of fungi isolated from in-patients and out-patients prompted an analysis of this topic. The studies were conducted with fungi from the collection of the Department of Mycology, University of Warmia and Mazury in Olsztyn, that were isolated from the oral cavity, sputum, bronchoscopic fluid, anus and skin from 100 in-patients and 100 out-patients.

Mycological monitoring of selected aquatic ecosystems in the context of epidemiological hazards. Drinking water.

Many species of microfungi are reported in aquatic ecosystems with different frequency. Their number constantly fluctuates depending on the concentration of environmental and anthropogenic factors. Drinking water, tap and bottled, is essential for the proper functioning of the human body.

Snow in the city as a spore bank of potentially pathogenic fungi.

This study evaluates the role of snow as a specific ecological niche and a vector in fungal spreading with particular emphasis on potential pathogens in seasonally and daily changing conditions. The experimental material was fungi isolated from the atmospheric air, snow cover, and fragments of ice and soil from underneath the snow cover. The total count of microfungi in the air before snowfall, i.

[Moulds isolated from the upper sections of the respiratory and alimentary tracts of healthy veterinary medicine students].

Background: The mycological studies in healthy veterinary medicine students have been prompted by the fact that only a few publications are available to date on the occurrence of moulds in people identifying themselves as generally healthy and having direct contact with ill or dead animals.

Material And Methods: The research material comprised swabs from the oral cavity, nasal cavity and throat of one hundred students (Faculty of Veterinary Medicine, University of Warmia and Mazury in Olsztyn) who declared good health. Initial cultures on the Sabouraud medium were incubated for 72 h at 37 degrees C, then sieved in the Czapek-Dox medium, where they were macroscopically assessed after two weeks.

Results of long-standing mycological analyses of biological materials originating from selected organ ontocenoses--yeast and yeast-like fungi.

This paper reviews the results of an extensive monitoring study, spanning 20-years of observation from three medical centres in Olsztyn on the dynamics and species diversity of fungi most frequently colonizing the respiratory and digestive systems of humans. The experimental materials were swabs and specimens from the gastrointestinal tract, swabs from the oral cavity and pharynx, as well as sputum and bronchial fluid from the respiratory system. The biological material was subjected to routine mycological diagnostics, taxonomic determination and identification.
