Form follows experience: the revitalization of postindustrial sites by carnivalesque

Recent decades are the times for intense socio-economic changes that have significantly influenced the forms of modern shaped public spaces. Freed brownfield sites, prior to transformation are spatial barriers by not integrated communication systems and are deprived of the existing functionality. This brings a risk of devastation and escalation of difficulties with the implementation of the new use. Over the years we have grown accustomed to the program that changes in the areas abandoned by the industry mainly due to the preferences and priorities of their managers and is a consequence of property rights. Models of revitalization strategy are based on the designation of the subject who rules, establishing core groups of beneficiaries to form planning regulations that are less strict than usual1. Significantly, this has a direct impact on the style of architectural intervention, the type of key investments and their functional program.Peer Reviewe

Pentachlorophenol and spent engine oil degradation by Mucor ramosissimus

Pentachlorophenol (PCP) has been widely used for many years and belongs to the most toxic pollutants. Spent engine oils enter environment every day in many ways. Both of them cause great environmental concern. In the present work we focused on identifying metabolites of PCP biodegradation formed in the cultures of Mucor ramosissimus IM 6203 and optimizing medium composition to enhance PCP removal in the presence of engine oil acting as a carbon source. Pentachlorophenol (PCP) to tetrachlorohydroquinone (TCHQ) transformation was the most interesting transformation conducted by the tested strain. TCHQ was further transformed to 2,3,5,6-TCP and 2,3,4,6- TCP. Strain IM 6203 is also capable of PCP transformation to corresponding anisoles – pentachloromethoxybenzene (PCMB) and pentachloroethoxybenzene (PCEB). Characterization of enzymatic background involved in PCP to TCHQ transformation showed that TCHQ formation is catalyzed by inductive and cytochrome P-450 dependent enzymatic system. Experiments conducted on mineral medium allowed defining the optimal quantitative and qualitative medium make-up for PCP to TCHQ transformation. Biodegradation of PCP on the optimized synthetic medium X was more efficient than on rich Sabouraud medium. The tested strain is capable of growing in the presence of spent engine oil therefore we checked the ability of PCP transformation on optimized synthetic medium containing oil as a carbon source. The obtained results showed that PCP removal and TCHQ formation occurred were found to be the most efficient on the oil containing medium (OX medium). PCP removal and TCHQ formation after 240 h of culturing reached 1.19 mg/l and 0.89 mg/l, respectively. Additionally, 55.5% of oil introduced to the medium was removed during 10 days of the experiment. PCP biodegradation mechanisms used by Mucor species have not been sufficiently explained. The presented results point to the tested strain as an interesting model for the research on fungal PCP biodegradation in the areas highly contaminated with engine oil and for its future application in PCP and oils removal

Survey on remnant data research: the artefacts recovered and the implications in a cyber security conscious world

The prevalence of remnant data in second hand storage media is well documented. Since 2004 there have been ten separate papers released through Edith Cowan University alone. Despite numerous government agencies providing advice on securing personal and corporate information, and news articles highlighting the need for data security, the availability of personal and confidential data on second hand storage devices is continuing, indicating a systemic laissez faire attitude to data security, even in our supposedly cyber security conscious world. The research continues, but there seems to be a lack of correlation of these studies to identify trends or common themes amongst the results. The fact that this type of research continues to be conducted highlights the deficiencies in the methods used to advertise warnings publicised by Government departments and industry experts. Major media organisations seem reluctant to broadcast these warnings, unless there is a bigger story behind the issue. This paper highlights the ongoing issues and provides insight to the factors contributing to this growing trend

Securing the Elderly: A Developmental Approach to Hypermedia-Based Online Information Security for Senior Novice Computer Users

Whilst security threats to the general public continue to evolve, elderly computer users with limited skill and knowledge are left playing catch-up in an ever-widening gap in fundamental cyber-related comprehension. As a definable cohort, the elderly generally lack awareness of current security threats, and remain under-educated in terms of applying appropriate controls and safeguards to their computers and networking devices. This paper identifies that web-based computer security information sources do not adequately provide helpful information to senior citizen end-users in terms of both design and content

THE DYNAMIC CIPHERS – NEW CONCEPT OF LONG-TERM CONTENT PROTECTING

In the paper the original concept of a new cipher, targeted at this moment forcivil applications in technology (e.g. measurement and control systems) and business (e.g.content protecting, knowledge-based companies or long-term archiving systems) is presented.The idea of the cipher is based on one-time pads and linear feedback shift registers. Therapidly changing hardware and software environment of cryptographic systems has beentaken into account during the construction of the cipher. The main idea of this work is tocreate a cryptosystem that can protect content or data for a long time, even more than onehundred years. The proposed algorithm can also simulate a stream cipher which makes itpossible to apply it in digital signal processing systems such as those within audio and videodelivery or telecommunication.Content protection, Cryptosystem, Dynamic cryptography, Linear Feedback ShiftRegisters, Object-oriented programming, One-time pad, Random key, random number generators,Statistical evaluation of ciphers.

Legal interest as a criterion for excluding a local councillor from voting

Artykuł dotyczy jednej z niezwykle ważnych instytucji prawa komunalnego, a więc regulacji dotyczącej ustroju samorządu terytorialnego, przynależącej jednocześnie do regulacji określanych mianem antykorupcyjnych. Rzecz dotyczy tego, w jakich sytuacjach radny – a więc członek organu stanowiącego jednostki samorządu terytorialnego ‒ nie może korzystać ze swego najbardziej podstawowego prawa, jakim jest prawo do udziału w podejmowaniu rozstrzygnięć, a więc prawo do udziału w głosowaniach. Autor artykułu stawia tezę, że wyłączenie korzystania z tego prawa może zachodzi jedynie wówczas, gdy głosowanie dotyczy takich sytuacji, w których radny występuje jako podmiot administrowany; nie dotyczy natomiast tych sytuacji, w których radny występuje jako przedstawiciel wspólnoty samorządowej. W artykule poddano krytycznej analizie dotychczasowe stanowisko doktryny oraz orzecznictwa.The paper deals with one of the major institutions of communal law: a regulation pertaining to the regime of self-government. This regulation is at the same time part of the provisions referred to as anti-corruption law. The question in focus is when a local councillor may be excluded from voting, or, in other words, be deprived of this basic right of participating in decision-making.It is then concluded that the exclusion of a local councillor’s right to vote may only be legitimate in the context of voting on matters in which a councillor is acting in the capacity of (or on behalf of) an administered entity. Exclusion may not occur, however, in situations in which a local councillor is acting as a representative of a self-governing community. Respective judicial decisions andopinions presented in the doctrine are subjected to critical analysis

On Be Star Candidates and Possible Blue Pre-Main Sequence Objects in the Small Magellanic Cloud

Recently the OGLE experiment has provided accurate light curves and colours for about 2 millions stars in the Small Magellanic Cloud. We have examined this database for its content of Be stars, applying some selection criteria, and we have found a sample of $\sim$ 1000 candidates. Some of these stars show beautiful light curves with amazing variations never observed in any Galactic variable. We find outbursts in 13% of the sample (Type-1 stars), high and low states in 15%, periodic variations in 7%, and the usual variations seen in Galactic Be stars in 65% of the cases. The Galactic counterparts of Type-1 objects could be the outbursting Be stars found by Hubert & Floquet (1998) after the analysis of Hipparcos photometry. We discuss the possibility that Type-1 stars could correspond to Be stars with accreting white dwarf companions or alternatively, blue pre-main sequence stars surrounded by thermally unstable accretion disks. We provide coordinates and basic photometric information for these stars and some examples of light curves.Comment: 9 pages, 8 figures, accepted for publication in Astronomy and Astrophysic

Alachlor oxidation by the filamentous fungus Paecilomyces marquandii

Alachlor, a popular chloroacetanilide herbicide, can be a potential health risk factor. Soil microorganisms are primarily responsible for conversion and migration of alachlor in natural environment, but knowledge concerning alachlor biodegradation is not complete. Therefore, we studied the ability of Paecilomyces marquandii, soil fungus tolerant to heavy metals, to eliminate alachlor and proposed a new pathway of its transformation. After 7 days of incubation only 3.3% of alachlor was detected from an initial concentration 50 mg L-1 and 20.1% from a concentration 100 mg L-1. The qualitative IDA LC-MS analysis showed the presence of ten metabolites. All of them were dechlorinated mainly through oxidation, but also reductive dechlorination was observed. The main route of alachlor conversion progressed via N-acetyl oxidation resulting in the formation of mono-, di- and trihydroxylated byproducts. N-acetyl oxidation as a dominant route of alachlor metabolism by fungi has not been described so far. The toxicity of alachlor tested with Artemia franciscana did not increase after treatment with P. marquandii cultures. Paecilomyces marquandii strain seems to be an interesting model for the research on alachlor conversion by soil microscopic fungi, due to its dechlorination and hydroxylation ability as well as high tolerance to heavy metals.Grant of the National Centre for Science in Cracow, Poland, No UMO-2011/01/B/NZ9/0289
