Opis:
Horace's Carmen saeculare has been given various evaluations so far. This being so, we are made to ask about the historico-literary context in which one should interpret this work, and which entitles us to characterize and evaluate it. The fact the poet introduced into the traditional form of hymn the current political affairs turned out to be the realization of the policies advocated by Augustus' propaganda (a genealogical, military, political and legislative aspect). Its expression were ludi saeculares alone. Their idea of the return of the golden age, bound with the person of Augustus, appeared as early as Virgil's poetry. The analogical symbolism of Carmen seaculare is also confirmed by the then iconography. In the structure of the work we find a counterpart of these links. It is the employment of the superior transmitting instance from without the text (Quindecemviri) and loading the dominating in the hymn preaction with the panegyric function.

Opis:
In the last book of Tristia the elegy in the Prologue presents the author’s awareness of the place of the collection he has just finished within the genre. Ovid juxtaposes it with the previous love elegy he wrote and with the love elegy of those times, and he reveals the constitutive elements of his new variation of the genre: first of all the dominating role of the subject of the poem who is identified with the creator of the presented world and with the author who is excluded from the literary life of those times. The distinctive situation of the lyrical statement motivates its style and composition based on the parallel of the subject and the tone and on the contrast of the past and the present. The sense of threat of his annihilation as a poet justifies the funeral metaphors and topic as well as the tone of lamentation, that in common awareness is associated with the archaic character of the genre that Ovid connects with the symbol of the flute. He is also aware of the continuity of the genre and hence he refers by name to representatives of the particular historical stages of its history. Following the Alexandrian scholars and Horace he talks about elegy in terms of the meter and according to the aptum rule he stresses the accordance of the subject matter with the threnodic tone. Referring to the primary form of the genre he develops the motif of auto-consolation. A personal confession of his exile experiences and the testimony of degrading circumstances add to the creation of protest and accusation. The authority of the many centuries of the genre convention gave the poet’s personal expression the power to affect the reader in many ages to come. This is why Tristia provide patronage to the modern elegy.

Opis:
We have recently witnessed an increase in the interest of Ovid's Fasti (Calendar). Despite that there is still a discrepancy in the understanding of the passages concerning the princeps. In the light of his poetry in exile they were regarded as panegyric, whereas the poet himself here and there refers clearly to his erotic writing. Augustus was fully aware about treating his actions as a kind of breakthrough, and he instrumentally treated the national calendar and the events, especially political, that were mentioned in it. Addressing his work as his own commentary to the princeps, Ovid seems to be unveiling his manipulations as regards the time, the place and the worship. He keeps an ironical distance towards the Augustan ideology which is manifested also in using many times the metaphor and phraseology approved by the official poets - Virgil and Horace. It is therefore a „foreign speech,” sometimes exposed in a hyperbolical or humorous manner. The poet does not leave his earlier ludic attitude, and declares loyalty to Venery, the hitherto patroness, despite the new theme: „ideam sacra cano.” Similarly, he perceives the person of the princeps. In the Fasti first of all the tone of an ironist sounds, the one who seemingly glories „nomina et titulos principis.” This tone of the work may be revealed by such reading that does not stop on the surface of its literal understanding.

The article presents some strategic aspects of the KOMAG Institute of Mining Technology in the field of creating innovative ideas and innovative technical solutions concerning machinery and devices for mining and preparation of minerals as regards their operational safety, productivity and reliability. Special attention is paid to a process of stimulating innovative ideas in a creative atmosphere, as KOMAG researchers and engineers are encouraged to be open-minded and to think in an unconventional way. Two examples of innovative technical solutions are described in detail, i.e. the water-and-air dust control system and the KOMTRACK haulage system for highly productive longwall systems of a new generation. The article contributes significantly to Innovation Engineering which is an important component of Production Engineering in the scope of generating and implementing innovative solutions. The authors presented an ecosystem of innovations, describing several methods of creating innovative ideas. The article concentrates on a role of Polish research institutes which play a key role in creating and implementing innovative solutions, bridging science and industry. Due to an analysis of different methods of generating innovative technical ideas and solutions, it can be concluded that an idea and a need of generating an innovative solution may appear in the research institute or at the industrial partner’s organization. In the case of the KOMAG multi-year experience and practice industrial partners include not only producers of mining machinery and equipment, but also representatives of mines of minerals. In general an innovative idea is generated in the result of an inspiration from the business environment and then it is transformed into an innovative product or service. The article contains the authors’ practical recommendations as regards a creation of innovative technical solutions. It is ended with a summary of general character and with some final conclusions.

Opis:
The aim of this study was to expand our knowledge about anticancer activity of some polyamine derivatives with quinoline or chromane as terminal moieties. Tested compounds were evaluated in vitro towards metastatic human prostate adenocarcinoma (PC3), human carcinoma (DU145) and mammary gland adenocarcinoma (MCF7) cell lines. Cell viability was estimated on the basis of mitochondrial metabolic activity using water-soluble tetrazolium WST1 to establish effective concentrations of the tested compounds under experimental conditions. Cytotoxic potential of polyamine derivatives was determined by the measurement of lactate dehydrogenase activity released from damaged cells, changes in mitochondrial membrane potential, the cell cycle distribution analysis and apoptosis assay. It was revealed that the tested polyamine derivatives differed markedly in their antiproliferative activity. Bischromane derivative 5a exhibited a rather cytostatic than cytotoxic effect on the tested cells, whereas quinoline derivative 3a caused changes in cell membrane integrity, inhibited cell cycle progression, as well as induced apoptosis of prostate and breast cancer cells which suggest its potential application in cancer therapy.

This article describes the problem of the CO2 emission permits market and introduces several important changes to the standard model, in particular a new goal function, transactions with price negotiations between regions and - as a consequence of introducing prices for permits – the possibility of investigating the influence of purchase/sale prices on the market. An additional novelty is the method of simulating such a market, which is based on a specialized evolutionary algorithm (EA).
Przedstawiono nowe podejście do symulacji rynku pozwoleń na emisję CO2. Pierwsza z prezentowanych w tej pracy nowych koncepcji polega na jawnym wprowadzeniu cen zakupu/sprzedaży do modelu rynku. Czynnik ten, pomijany w dotychczas stosowanych modelach, może mieć znaczny wpływ na rynek, a zwłaszcza na podejmowanie decyzji kupna/sprzedaży i – w konsekwencji – także na ilości sprzedanych pozwoleń. Dlatego też powstał model oparty na bardziej realistycznych założeniach, który został porównany z modelem tradycyjnym. Zastosowano w nim kilka istotnych modyfikacji, takich jak zmodyfikowana funkcja celu i transakcje z negocjacjami cen pozwoleń na emisję. Kolejną innowacją jest zastosowanie algorytmu ewolucyjnego do symulacji rynku. Algorytmy ewolucyjne są obecnie dość często używane nie tylko jako efektywne algorytmy optymalizacyjne, ale stosuje się je również do symulacji różnego typu systemów ekonomicznych, gier i rynków. Takie zastosowania algorytmów ewolucyjnych znane są pod angielską nazwą Agent-Based Computational Economics (ACE).

Introduction and objective. Several studies have reported therapy failures in patients with legionnaires’disease; however, antimicrobial resistance of clinical and environmental isolates of Legionella spp. has not yet been documented. Routine susceptibility testing of Legionella spp. is not recommended because of difficulties in determining standard minimal inhibitory concentration values. The purpose of this study was to analyze the antimicrobial susceptibility of Legionella pneumophila. strains isolated from a water supply system. Materials and method. Twenty-eight isolates of L. pneumophila (16 – L. pneumophila SG 1, 12 – L. pneumophila SG 2–14) obtained from water systems in public buildings in Poland were tested. Susceptibility testing was performed using the E-test method. The tested antibiotic were azithromycin, ciprofloxacin, and rifampicin. The medium used for the susceptibility testing was BCYE-, a special medium for Legionella cultivation. Results. Among the tested strains, L. pneumophila was the only one resistant to azithromycin. It was a strain of L. pneumophila SG 2–14 isolated from the water system in a sanitorium. All isolates were found to be sensitive to ciprofloxacin and rifampicin. However, the azithromycin-resistant strain exhibited higher ciprofloxacin and rifampicin MIC (1.5 μg/ml, and 0.19 μg/ml, respectively). The MIC50 for azithromycin, ciprofloxacin, and rifampicin were 0,032, 0,125, and 0,003 μg/ml, respectively. The MIC90 for azithromycin, ciprofloxacin, and rifampicin were 0,032, 0,125, and 0,003 μg/ml, respectively. Conclusions. Azithromycin resistance was found in one strain of L. pneumophila SG 2–14, but the resistance mechanism is unknown and needs further study. It is possible that therapeutic failures in Legionnaires’ disease may be associated with bacterial resistance which should be taken into account. The antibiotic sensitivity testing described in this study could be helpful in detecting the resistance of clinical L. pneumophila isolates. Ciprofloxacin and rifampicin have good in vitro activity against environmental L. pneumophila SG 1 and SG 2–14 in Poland.

Objectives Polish Labour Code provides employees with a range of solutions (benefits) supporting them in achieving balance between work and private life. This paper was aimed at indicating availability and the use of legal benefits supporting work-life balance (WLB) among Polish workers of small and medium enterprises. Material and Methods The study sample included 219 respondents, aged 22–64, working in small and medium enterprises and employed on the basis of employment contracts for at least a year. The respondents completed a questionnaire on availability and the use of benefits guaranteed by the Polish Labour Code, referring to their current workplaces. Results Most frequently the studied employees took sick leave because of one’s own illness and leave on demand. In our sample, 45% of the women took maternity leave and 26% of the men took paternity leave. The respondents took educational and parental leave the least frequently. More than half of the respondents (58%) did not return to the same position after leave devoted to childcare, even though they had such a possibility. Conclusions In fact, most of work-life balance benefits guaranteed by law were available to the employees of small and medium enterprises, regardless of their gender. Availability and the use of the majority of benefits were similar among the women and men. Availability of benefits depended on the specificity of industry and a profession, thus, future research on work-life balance policy should control for variables related to the character of work.

The chemicals were tested in the laboratory on mosquitoes caught in the nature and the contact method was employed. Propctamphos and Permethrin at concentrations 0.05% and 0.1 %, after 2 hours of 1 hour exposure reduced the mosquitoes in 96% and 99.9% respectively. Iodofenphos and Dioxacarb, even at concentration 0.1 %, after 24 hours of 1 hour exposure caused barely 78.3% and 83.9% mortality of these insects. Both insecticides tested, in the 7 days period after the spraying, caused more than 97% reduction of the Anopheles population in the cow-sheds.

Opis:
Cel: Artykuł ma na celu: podsumowanie i ocenę dotychczasowej aktywności badawczej pol-skich autorów w dziedzinie etyki rachunkowości; wskazanie głównych nurtów badań empi-rycznych i uporządkowanie ustaleń badawczych; ustalenie i ocenę zakresu raportowania poszczególnych elementów procesu badawczego; wyłonienie luk poznawczych, stanowią-cych inspirację do podjęcia dalszych badań. Metodyka/podejście badawcze: Wykorzystano metodę systematycznego przeglądu lite-ratury, w tym analizy bibliometrycznej oraz analizy treści 35 publikacji. Wyniki: Etyka w rachunkowości jako obszar badawczy znajduje się obecnie dopiero na etapie rozwoju. Zauważa się przy tym rozproszenie zainteresowań badawczych. Najczęściej podej-mowanym wątkiem badawczym było zidentyfikowanie motywów i przyczyn nieetycznych zachowań. Wszystkie badania, z wyjątkiem jednego, opierały się na nielosowym doborze próby. Zdecydowana większość badań miała charakter ankietowy, gdzie w połowie przy-padków grupę badawczą stanowili studenci. Sformułowano zalecenia odnośnie do rygoru metodologicznego dalszych badań, ponieważ zauważone braki w tym zakresie uniemożli-wiają replikację tych dotychczasowych. Ponadto dzięki zidentyfikowaniu luk badawczych określono kierunki dalszych dociekań naukowych. Ograniczenia/implikacje badawcze: Ograniczenie przeglądu wyłącznie do czasopism naukowych wynikało z konieczności ujednolicenia źródeł publikacji wyników badań. Oryginalność/wartość: Wnioski z dokonanego przeglądu mogą stanowić inspirację do podejmowania badań w nieeksplorowanych dotąd obszarach, a także być wskazówką do zapewnienia jak najlepszej ich jakości.

Opis:
West Nile virus (WNV), the etiologic agent of West Nile Fever (WNF), an emerging infectious disease that lately has been rapidly extending its range of occurrence from Africa to Middle East, and to Asia and Southern Europe. In Europe, cases of isolating WNV from mosquitoes representing four genera have been reported from Romania, Portugal, France, southern Russia and what is the most important, from Poland’s neighbouring countries as the Czech Republic, Slovakia and southern Ukraine. These data, as well as human and equine cases in the Czech Republic and Belarus, support hypothesis that WNV has already been present also in Poland, the more so, specific antibodies were detected in the sera of birds collected at the Kampinos and Bialowieza Primeval Forests and in human from the vicinity of Bialystok. Mosquitoes were collected in 2004–2009 at indoor and outdoor collection sites in districts: Kujawsko-Pomorskie, Mazowieckie, Podlaskie and Warmińsko-Mazurskie. In total 15400 female mosquitoes were collected in the cow sheds and overwintering in the cellars, and from human bait and CO2 traps. Mosquitoes were sorted by the collecting site, species and sex, and placed in pools of not in more than 50 specimens in special mixture of phenol and chaotropic salts and frozen in –20°C. Altogether, 15400 females were examined. Total RNA were extracted according to protocol of A&A Biotechnology. RT reaction was performed with random primers and 217-nucleotide fragment from the NS5 coding sequence was amplified by heminested PCR. PCR products were analysed on 1.5% agarose gel. The predominant species was Culex pipiens, accounting for over 42% of total insects collection. All obtained results were negative. Further investigations are needed.
