New and rare species for Poland’s diatom flora

Taxonomic and ecological analysis of 21 diatom species was carried out. 13 of them have not been recorded in Poland until the present study; they are: Amphora montana Krasske, Navícula erifuga Lange-Bertalot, N. goeppertiana (Bleisch) H. L. Smith, N.joubaudii Germain, N. libonensis Schoeman, N. oppugnata Hustedt, N. novaesiberica Lange-Bertalot, N. recens (Lange-Bertalot) Lange-Bertalot, N. stroemii Hustedt, Neídíum bisculatum var. subamplialum Krammer, Pinnularia ignobilis (Krasske) Cleve-Euler, Stauroneis lauenburgiana Hustedt, St. wislouchii Poretzky & Anisimowa. 11 of these taxa (underlined) as well as Caloneis latiuscula (Kützing) Cleve and C. molaris (Grun.) Krammer are rare species for Polish and world diatom floras. 6 taxa have been described due to changes in their nomenclature introduced by Lange-Bertalot (1986, 1993), and new localities of their occurence in Poland are also given. These species are: Caloneis alpestris (Grun.) Cl., N. laterostrata Hust., N. rynchocephala Kütz., N. rynchotella Lange-Bertalot, N. subminuscula Manguin and Pinnularia stomatophora (Grun.) Cl.Zadanie pt.

The work contains some remarks on the taxonomy and ecology of the 23 diatom taxons from the genus Navicula Bory to be found in the microbenthos of 3 rivers of Central Poland: Bzura, Mroga and Rawka. The data concerning diatom dimensions as well as the number of striae per 10 µm have been compared with those given by Hustedt (1930), Cleve-Euler (1953), Patrick, Reimer (1966), Germain (1981) and Kramer, Lange-Bertalot (1986).Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 zostało dofinansowane ze środków MNiSW w ramach działalności upowszechniającej naukę

Problemy orzecznicze Krajowej Izby Odwoławczej

The article is of a scientific and research nature and presents concisely the problems related with the case law of the National Appeals Chamber (Pol. Krajowa Izba Odwoławcza). On 5 December 2007, the National Appeals Chamber was established, also referred to as the Chamber, which replaced Arbitrator Teams in hearing the appeals. Each year, the Chamber issues a total of 2,500 to 3,000 judgments, which are essentially the fundamental pillar of the functioning of the public procurement system. The adjudication difficulties that have arisen over the years and remain valid are: vagueness of the legal regulations, lack of transitional provisions, frequent law amendments, unusual speed of proceedings and, above all, marginal instance review of the decisions of the Chamber. However, judicial uniformity has been achieved on several important issues, thanks to resolutions passed by the Supreme Court. It was concluded that the determination of the gross price in the tender, taking into account the incorrect rate of tax on goods and services, constitutes an error in the calculation of the price if there are no statutory conditions for a mistake The ground for an appeal against the choice of the most advantageous tender may also include failure to exclude an economic operator who has submitted a tender chosen by the contracting entity or failure to reject a tender that is subject to rejection. The Supreme Court ruled that if a tender is submitted by a consortium, the correctness of the bid bond in the form of an insurance guarantee would be determined by the content of the guarantee. Uniformity of case law may be ensured by the appointment of a single court having jurisdiction in public procurement matters at second instance. It would also be helpful to organise specialist training at the highest substantive level.Artykuł ma charakter naukowo-badawczy, w sposób przekrojowy przedstawia problemy związane z orzecznictwem Krajowej Izby Odwoławczej. Z dniem 5 grudnia 2007 r. powstała Krajowa Izba Odwoławcza, zwana także Izbą, która zastąpiła dotychczas rozpatrujące odwołania Zespoły Arbitrów. Izba wydaje w każdym roku 2500–3000 orzeczeń, które są w zasadzie podstawowym filarem funkcjonowania systemu zamówień publicznych. Trudności orzecznicze, jakie pojawiły się na przestrzeni lat i nadal pozostają aktualne, to: niejasność regulacji prawnych, brak przepisów przejściowych, częste nowelizacje, niezwykła szybkość postępowania oraz przede wszystkim marginalna kontrola instancyjna orzeczeń Izby. Udało się jednak doprowadzić do jednolitości orzeczniczej w kilku ważnych kwestiach dzięki uchwałom podejmowanym przez Sąd Najwyższy. Rozstrzygnięto, że określenie w ofercie ceny brutto z uwzględnieniem nieprawidłowej stawki podatku od towarów i usług stanowi błąd w obliczeniu ceny, jeżeli brak jest ustawowych przesłanek wystąpienia omyłki. Zarzut odwołania od wyboru najkorzystniejszej oferty może obejmować także zaniechanie wykluczenia wykonawcy, który złożył ofertę wybraną przez zamawiającego lub zaniechanie odrzucenia oferty, która powinna podlegać odrzuceniu. Sąd Najwyższy uznał, że w przypadku złożenia oferty przez konsorcjum o prawidłowości wadium w formie gwarancji ubezpieczeniowej decyduje treść tej gwarancji. Jednolitości orzeczniczej może służyć powołanie jednego sądu właściwego w sprawach z zakresu zamówień publicznych w drugiej instancji. Pomocne byłoby również organizowanie merytorycznych szkoleń na najwyższym poziomie merytorycznym

Female unemployment trends in rural areas of Poland in 2008-2012

This paper, firstly, identifies the scale and spatial differentiation of registered female unemployment in rural areas of Poland, defined according to the new Degree of Urbanisation (DEGURBA) classification of LAU2 regions used in the European Union (EU) for the Labour Force Survey, since the onset of the global economic crisis, and secondly, investigates the reasons for the occurrence of very high female unemployment rates that are either stable or increasing and very high gender gaps in unemployment rates. Quantitative analysis identified 27 rural communes in Poland affected by such problems. Most are situated in the north and several in the south-east of the country, mainly in post-state-owned farming areas. The results of semi-structured telephone interviews with representatives of local authorities of nine of those communes indicate that despite the different locations and different types of LAU2 regions, female unemployment is caused by similar factors: liquidation of state-owned farms not followed by any new job opportunities, peripheral location not attractive for external (out-of-commune) investors, lack of entrepreneurial skills, experience and finance to start own businesses, low income or poverty of inhabitants significantly limiting the purchase of goods and services, thus limiting the demand that could be met by local SMEs, and finally liquidation of enterprises, quite often the only employers in the commune. The problem of female unemployment cannot be solved by local authorities as they lack sufficient legal and financial resources, and needs to be addressed by both the government and the EU within actions of the Europe 2020 Strategy

Technology Assessment: a tool of Technology Failure Prevention

Technology plays an increasingly important role in health care. Failures and unpredicted effects of health technology may lead to disastrous consequences such as injuries and casualties, but they also mean huge financial costs, waste of resources, legal issues and loss of public trust for medical care systems and health technology industry. Therefore, technology failures should be prevented for the sake of patients, functional health care systems and technological advancement. The objective of this thesis is to indicate, that properly conducted technology assessment (TA) is critical for preventing failures. Short theoretical background is presented draw a more comprehensive picture of TA, its functions and origins. A literature review has been performed to find those ingredients of technology assessment, which are essential from the perspective of failure prevention. Such elements are objectivity and impartiality, planning, choosing assessment criteria, foreseeing adverse effects, technology comparison, and periodical reassessments. To underline the vitality of properly conducted TA, an example of metal-on-metal hip implants failure is introduced. The reasons for failure are analysed and prevention steps, which should have been implemented, are proposed. This thesis is an approach to TA seen as a practical and essential tool. It is an attempt to demonstrate, that TA should be of great interest for biomedical engineering. Since biomedical engineers are professionals, who design and manufacture health technology, TA provides a great methodology for them to improve the whole innovation process. TA is also important for better understanding of technology development paths and their consequences

Diatoms of the Dobrzynka River at the town of Pabianice, Central Poland

The Dobrzynka River is a left tributary of the 21.5 km long Ner River. Benthos samples were collected at the town of Pabianice, where the river is affected by communal-industrial sewage inflowing from a sanatorium at the village of Tuszynek, from the southern part of Pabianice and the „Pamotex” Cotton Mill. On the basis of 15 samples 97 diatom taxa were identified (Tab. I). Table II presents 5 dominant taxa (above 5%) and 9 subdominant taxa (2-5%). 18 constant species (81-100% of samples) were distinguished. Saprobity was determined for 84 species (Hofmann 1994, Lange-Bertalot 1994). On the basis of sapro-biological analysis the Dobrzynka River water at Pabianice may be characterized as α-β-mesosaprobic, which attributes the water to Water Purity Class II (Turoboyski 1979).Zadanie pt.
