The present study investigated the effectiveness of three different disinfectants: preparation H1 (two-component preparation based on hydrogen peroxide); Pedox (multi-component preparation based on peroxyacetic acid) and Savo hypochlorite preparation) against Malassezia pachydermatis. The antifungal activity of disinfectants was tested by quantitative suspension method according to STN EN 1650. The results confirmed 100% effectiveness of these disinfectants at all concentrations and exposure times tested.
Subject and purpose of work: This paper aims to assess the operational efficiency of public higher vocational schools in the Lublin Region. Materials and methods: The assessment was based on the non-parametric method of data envelopment analysis (DEA) using the standard CCR-O model. Results: In most of the analysed models (E, N, O series), the public higher vocational schools in the Lublin Region were found to have improved their efficiency in 2019 relative to 2017. Conclusions: E-series models are very susceptible to changes, both in terms of inputs and effects. This gives the possibility of a significant impact on the increase in the assessment of the effectiveness of investigated units DMUs. N-series models demonstrate the importance of aggregation and quality of source data for the results of performance assessment. Class O models justify the need to look for and compare the use of other DEA model variants in the study of the effectiveness of public higher vocational schools.
The paper includes the results of measurements of timber logs sorting by a modern, equipped with the newest measurement and steering systems line for automatic pretreatment of timber materials. The examined research was made in one of sawmills of Pomeranian Voivodeship.
Background: The purpose of the following research was to find out the influence of imaginary training based on intention implementation on throw effectiveness of young basketball players, both male and female in stressogenic situations. Individual differences (action vs state orientation) between players were also measured in this research. Material/Methods: 76 players (32 females and 44 males) in the cadet category (15-16 years old) from basketball clubs of Gdansk, Gdynia and Sopot took part in this research. In the first stage all players did a throw efficiency test ERPE 05 under two conditions, and their heart rate was measured. Then players were randomly assigned to one of two groups. The first one did imaginary training based on the influence of intention implementation for 10 days, while the other did not. After 10 days ERPE 05 test under two conditions was run again. Results: Test results showed that intention implementation does not influence effectiveness improvement in stressogenic conditions as far as state-oriented players are concerned, but it does lower the physiological cost of physical effort in form of a decreased heart rate. Conclusions: This research proves that visualization training based on implementation instructions does influence young players’ physiology and significantly lowers their heart rate under stressogenic conditions. However useful, visualization techniques used in this research still need other tests and should be applied for a longer period of time to acutely show how they affect young players’ mental preparation.
The sources for the given subject research were preliminary organisational structures and systems of tax administrations that are currently in place in Slovakia as well as in Hungary, Poland, the Czech Republic and Slovenia. The basic presumption of the research is the increase of the system effectiveness en bloc. Based on the trends analysis we assume, that the upcoming reform of the Tax and Customs Administrations shall contribute significantly to the increase of the system effectiveness and at the same time bring along the improvement in positive perceiving of taxes, seen by public as socially unpopular obligations.
According to the obtained results we can state that the surveyed group of junior school teachers know the assumptions on the project method but use this method of work with different frequency. The teachers are aware of same difficulties and restrictions concerning this method of work in reference not only to their own workshop but also to school conditions. They can identify the restricitng factors. The obligatory introduction of the project method to the third stage of eduction will increase its usage while teaching-learning practice but the question stili remains: will the effectivness of geography teaching increase? The answer to this question may only be obtained by conducting the survey in this field.
Economics of quality is a trendy area of quality management. Nobody doubts the need to monitor and evaluate the costs related to quality. However, there were significant divisions by experts in the field, which is also reflected in practice. In our contribution, therefore, deal with it rather than theoretical knowledge is converted into company practices.
The purpose of this study was to determine the effectiveness of photocatalytic ionisation as a disinfection method for filter materials contaminated by microorganisms, and to assess how air relative humidity (RH), time and microbe type influence the effectiveness of this disinfection. In the quantitative analysis of a used car air filter, bacterial contamination equalled 1.2×10⁵ cfu/cm² , fungal contamination was 3.8×10⁶ cfu/cm² , and the isolated microorganisms were Aspergillus niger, Bacillus megaterium, Cladosporium herbarum, Cryptococcus laurenti, Micrococcus sp., Rhodotorula glutinis and Staphylococcus cohnii. In the model experiment, three isolates (C. herbarum, R. glutinis, S.cohnii) and 3 ATCC species (A. niger, E.coli, S. aureus) were used for photocatalytic ionisation disinfection. The conditions of effective photocatalytic ionisation disinfection (R≥99.9%) were established as 2–3 h at RH=77% (bacteria) and 6–24 h at RH=53% (fungi). RH has an influence on the effectiveness of the photocatalytic disinfection process; the highest effectiveness was obtained for bacteria at RH=77%, with results 5% higher than for RH=49%. The studies show that the sensitivity of microorganisms to photocatalytic ionisation disinfection is ordered as follows: Gram-positive bacteria (S.cohnii, S. aureus), Gram-negative bacteria (E.coli), yeasts (R. glutinis), and moulds (C. herbarum, A. niger). Of all the mathematical models used for the description of death dynamics after photocatalytic ionisation disinfection, the Chick-Watson model is the most useful, but for more resistant microorganisms, the delayed Chick-Watson model is highly recommended. It therefore seems, that the presented disinfection method of photocatalytic ionisation can be successfully used to clean filtration materials.
The time within which, accordingly to its application, machine works, and an object of work and working groups are under load, is the effective active time. The purpose of the research was the order statistics of effective active time of limbing and conversion at chainsaw use in two technology and two habitat variants. The effective active time of limbing and conversion of one tree was most frequently from 0.5 s to 10.49 s in variant in which the limbing included tree crowns and only thicker branches cutting and the conversion included rods meant for chipping. The strong tree’s branching in fresh mixed coniferous forest had influence on the prolonged limbing time. The share of S2a assortment in total volume of harvested wood had influence on the conversion time, besides the number of wood assortment cutting.
The paper presents the problem of the financial access to medications and possibilities to improve the situation. One of the possibilities is the legal practice of parallel import. The problem of differences in medication prices is vital, for they are substantial between various countries. The paper points out that efforts to enable patients to take efficacious medicine, regardless of the place of residence, are necessary.
The paper presents results of mycological tests and accelerated ageing tests for 13 commercially available decorative coatings in relation to costs of their purchase. Mycological tests with the use of A. niger showed that only four preparations protect spruce wood against attack of the test fungus. None of the coatings was resistant to the destructive effect of UV radiation. Testing results of resistance against A. niger attack and accelerated ageing were compared relative to purchase costs of the applied preparations. It was found that the most advantageous preparations were those with medium efficacy and of low prices. However, for the comprehensive economic analysis of the application of tested decorative coatings it is required to consider costs of coating application and surface renovation.
Clinical studies were carried out in the period of 2003-2008 at the Provincial Children’s Rehabilitation Hospital in Ameryka near Olsztyn (Poland). The study involved a group of children and youths exhibiting spinal deformity progression in idiopathic scoliosis (IS) of more than 5o per year according to the Cobb scale. Four hundred and fifty patients between 4 and 15 years of age were divided into three groups (n = 150). Group I received 2-hour and group II 9-hour treatment of Lateral Electrical Surface Stimulation (LESS), respectively, whereas group III (control) was treated only with corrective exercises for 30 minutes twice a day. LESS was performed as 24-month treatment with the use of a battery-operated SCOL-2 stimulator manufactured by Elmech, Warsaw, Poland. The effectiveness of this method was confirmed in the treatment of spinal IS in children and adolescent patients, especially when the initial spinal deformity does not exceed 20o according to the Cobb scale. A short-duration electrostimulation – 2 hours daily – was found to produce results similar to those obtained after overnight, 9-hour electrostimulation. Moreover, the analysis of the Harrington prognostic index F confirms the positive effect of LESS in both groups of patients (2 h and 9 h of LESS).
