Opis:
The dynamics of the processes taking place in an environment, which is rendered in the altered perception of the character of this environment, induces a need to find answers to the following questions: (1) How do managers perceive an environment in the dimensions of stability/ changeability and friendliness/unfriendliness? (2) Is there a correlation between the stability/changeability and friendliness/unfriendliness of an environment, i.e. if an environment is more stable, is it perceived as more friendly, and if an environment is more changeable is it perceived as unfriendly? (3) Does environmental stability/changeability as well as friendliness/unfriendliness exert any influence on organizational effectiveness? In an attempt to answer the above quoted questions, the article’s objective has been defined as a discussion on the interdependencies perceived by managers between an environment’s dimensions of stability/changeability and friendliness/unfriendliness (analysed in terms of institutional categories) and the organizational effectiveness of Polish enterprises. The managers evaluated the legal environment as the least stable. In their opinion, that milieu was also more intimidating than friendly. Concurrently, a technological environment was perceived by the respondents as the most stable and favourable. The results of the effected research allow forming a conclusion concerning the existing correlation between the friendliness and stability of particular categories of an environment, at the same time pointing out to the occurrence of correlations between stability/changeability and friendliness/unfriendliness of some categories of an environment and the organizational effectiveness of the examined enterprises.

Opis:
The article discusses the methods of defining and describing the processes of learning in what is generally acknowledged as the learning environment. In the contemporary pedagogical discourse the category of the “learning environment” (formerly associated with the surroundings of school and the classroom) is always expanding and acquiring new meanings, in the wake of ecological changes and the virtualisation of contemporary culture. The “learning environment” becomes a part of the ongoing descholarisation, which manifests itself, for example, in the “open space” movement, outdoor education or “Gesamtschule”, the trends related to the transfer of education outside of school. In the last part of the text, a postulate is formed to include a “learning for the environment” category to the pedagogical theory and practice. This stems from the need to deepen the social sensitivity of the threat of degradation of the entire ecosystem in which we live today.

Opis:
The presence of fluoride in exceeding limits and related problems of drinking water prevailing in many parts of India is well documented. Fluoride in drinking water is known for having both beneficial and detrimental effects on health. Many solutions to these problems were also suggested. Fluoride from water or wastewater can be removed by an ion exchange/adsorption process or by a coagulation, precipitation process. The ion exchange/adsorption can be applied to either concentrated or diluted solutions and they are capable of achieving complete removal under proper conditions. The method suitable for a given situation needs to be judiciously selected considering the various aspects. The paper presents the current information on fluoride in environment and its effects on human health, as well as available methods of defluoridation in detail.

Opis:
The aim of this work was to estimate mobility of pollutants contained in ashsludge granulates, expressed by their possibilities of elution by water and by estimating their potential danger to the environment. Materials used in experimental research (one stage leaching tests) was ash-sludge granulates made of two different kinds of waste: fly ashes from brown coal (30%) from 'Bełchatów' Powerplant and communal sewage sludge (70%) from municipal sewage treatment plant in Zabrze (southern Poland). However sewage sludge are an alternative to organic fertilizers (e.g. manure) and nitrogen and phosphorus content is relatively high but potassium concentrations are much less. Tested sewage sludge were modified by various potassium salts, which would improve their fertilizing abilities because potassium is easy-leaching element during sewage treatment. In first part of sewages KCl and in second K2SO4 were used both in load 344 g/kg d.m. Blank tests were carried on unmodified material. One stage leaching test were carried and equilibrium was reached after 24 hours. Water extracts (eluates) were analyzed for presence of nitrogen group compounds, phosphorus, chlorides, sulphates, magnesium, calcium and heavy metals. Also loads of particular compounds were calculated. On the basis of research (leaching test) there has been calculated a load of the pollution that were being washed out in mg/kg dry mass of used granulates. Eluates obtained in one-stage leaching tests had alkaline pH and high EC value which rise with potassium concentrations. In eluates from tested materials some parameters (e.g. ammonium, nitrites, COD, sulphates and potassium) exceed polish limits for sewages discharged to waters and grounds. Especially high were chlorides concentrations (10 times to high) due to KCl content. The highest heavy metals concentrations were observed in eluates from granulates modified by K2SO4 due to lower pH value in comparison to unmodified material. In next step in this researches will be to find optimal balance between fly ash and sewage sludge and use compounds for pH corrections.

Opis:
Assessment of the stability of a genotype to different environments is useful for recommending genotypes for known conditions of cultivation and should be a requirement in plant breeding programs. Nonparametric models do not require parametric assumptions and are good alternatives for parametric measurements to genotypes × environments (GE) interaction study.Twelve maize (Zea mays L.) genotypes were tested at eleven locations in for two years (22 environments). The experiments involved a randomized complete block design in which twelve nonparametric procedures were used to analyze genotype stability. Results of nonparametric tests of GE interaction and combined ANOVA showed there were both noncrossover and crossover GE interaction...

The subject of the considerations contained in the study is an attempt to determine whether when creating the content of Art. 4 of the Act of April 27, 2001, Environmental Protection Law, was used as a model for solutions regarding the use of water contained in the Water Law Act. This view is expressed quite often in the reference literature. The analysis carried out in this paper proves that such a view is not sufficiently justified, as evidenced primarily by significant differences in the regulation method used in Art. 4 and in the Water Law Act.

Opis:
Interaction Analysis has been explored for the initiating topics, turn taking, and asking and answering questions in face-to-face learning environments during the last decades. This study investigated the form and sequence of the questions and answers in an asynchronous environment from a non-interventionist point of view. To conduct the research, 16 questions and answers from the discussion boards of an eight-week international online research course from 30 participants were copied, classified, and analyzed according to the Hmelo-Silver and Barrows’ (2008) grid. All the questions were classified as long-answer, short-answer, and task-oriented questions and their frequencies were calculated. Also, the presence of the Initiation, Response, and Feedback/Inquiry (IRFI) pattern was examined The results indicated that the largest number of questions fell under long-answer types and the participants were more motivated in responding the long-answer queries relating directly to the immediate studied materials or asking about definitions and personal ideas. The findings supported the idea that IRFI pattern might not be applicable in asynchronous environments. Therefore, the instructional patterns need to be designed carefully according to the needs of the new contexts. This study could enhance meaningful interactions in online educational settings such as language learning, teacher training, and professional development.

Opis:
Goal The goal of this article is to present the author’s definition of security environment. It constitutes a redefinition and expansion of the narrow (four-element) approach presented in the White Book on National Security of the Republic of Poland. I propose a broad, eight-element approach. Methods I redefine security environment based on several premises. The first is the concept of the triangle of (the need for) security – the existence of this triangle necessitates and is sufficient for the need for security to arise. The second premise is the existence of the rhombus of security (culture), which necessitates and is sufficient for security to manifest, i.e. for the need for security to be satisfied. Results The above premises lead to the conclusion that the narrow approach to security environment should be ontically expanded to include elements comprising the triangle of the (need for) security and the security (culture) rhombus. This results in an eight-element definition of security environment. Conclusions The article illustrates an important issue in the security sciences – the need to expand the definition of security environment. I present and justify an alternative to the narrow approach to security environment, which is based on the narrow definition presented in the White Book on National Security of the Republic of Poland.

Opis:
In the paper a probabilistic model of environmental risk of ship power plant is presented. This is a linear strategy model with an additional restraint. It can be usedfor assessing risk to marine environment, which results from ship power plant operation. The risk is a sum of component probabilities of exceedance of the limits assigned - by MARPOL convention to particular kinds of pollution discharged from ships, multiplied by weight factors. The factors determine a degree of harmfulness of a discharge for the environment. The restraint concerns the case of exceedance of the limits assumed unacceptable by the convention. A risk value is be contained within (0,1) interval. Moreover a criterion for environmental safety of ship power plant was propsed. This is the criterion of the ALARP class, in which an intolerable risk level and acceptable one is distinguished. Suggestions concerning determination of the levels are submitted. The considerations are illustrated by results of example computer investigations of influence of reliability oftechnical elements of the systems responsible for environmental safety of a hypothetical ship power plant on environmental risk value. Three qualification levels of ship:s. crew were accounted for: high, average and low.

Measles-mumps vaccinations might be responsible for the development of autism spectrum diseases (ASD), including high functioning autism, such as Asperger’s syndrome; that is what Wakefield et al. suggested in a paper in The Lancet twenty years ago [1]. Later, the Lancet Editors retracted this publication [2], due to the fact that Wakefield had „produced“ fake, falsified results, and that he was implicated in interests regarding material compensation from pharmaceutical companies producing vaccines to families with ASD. The Wakefield publication had the effect that consequently vaccination rates declined dramatically, and fuelled discussions about other environmental factors (bacteria, mercury, pesticides, etc.).

Opis:
The pH dependence of adsorption reactions of cationic metals is due, in part, to the preferential adsorption of the hydrolyzed metal species, in comparison to the free metal ion (McBride, 1977; McLauren and Crawford, 1973; Davis and Leckie, 1978; Farrah and Pickering, 1976a,b; James and Healy, 1972; McBride, 1982; Cavallaro and McBride, 1980; Harter, 1983). The pH of the soil system is a very important parameter that directly influences sorption/desorption, precipitation/ dissolution, complex formation, and oxidation-reduction reactions. In general, maximum retention of cationic metals occurs at pH>7 and maximum retention of anionic metals occurs at pH<7. However, because of the complexity of the soil-waste system, with its myriad of surface types and solution composition, such a generalization may not hold true. For example, cationic metal mobility has been observed to increase with increasing pH due to the formation of metal complexes with dissolved organic matter.

Opis:
Biosurfactants are surface-active molecules produced by variety of microorganisms like bacteria, yeasts or fungi. They consist of both hydrophilic (polar head) and hydrophobic (non-polar chain) moiety. Such structure allows them to reduce interfacial tension or create microemulsions. Biosurfactants can be produced as a part of cell membrane or extracellular compounds. They show foaming, wetting, emulsifying and dispersing properties. Biosurfactants are characterized by low toxicity, high biodegradability and they do not accumulate in living organisms. Biosurfactants are mostly used in environmental clean-up technologies. However due to many properties biosurfactants find use in various industries, such as: petroleum, pharmaceutical, textile or cosmetic. Microbial surface active compounds can improve the degradation of hydrocarbons from soil and water. Besides they are capable of degrading polycyclic aromatic hydrocarbons (PAHs). Biosurfactants help removing heavy metals like lead, cadmium or zinc, from soil. Rhamnolipids synthesized by bacteria of the Pseudomonas aeruginosa are the most commonly used biosurfactants in the remediation process. The aim of this paper is to present different applications of biosurfactants in environmental remediation based on literature review. The paper is based on literature studies.

The present article aims to reflect on the relationship of man to nature, namely the relationship of culture and environmental crisis. The following considerations are largely based on the one hand, the concept of evolutionary ontology Šmajs Joseph, on the other hand, the idea of Erich Fromm that in the context of the environmental crisis and its relation to culture and humanity offer attractive incentives for reflection. This concerns in particular the attempt to develop a more moderate approach that could serve as an acceptable platform for further reflection on this issue. While such an approach is based on the traditional view on this issue, which in the last century attempted to justify the extension of moral respect to all living flesh, no response yet on their weaknesses and try to give new impetus to the still current discourse. Therefore your attention article focuses on reflection on the transformation of culture that in these contexts, the words ŠMAJS appears to be an evolutionary possibility and an existential necessity.

Investigations of bacteriophages showed that in the environment are mostly in water, but in small municipal lakes sporadically been studied. Previous studies of bacteriophages in the aqueous environment related to the determination of the quantity and diversity and use them as indicators of water pollution. In the last study probably of the most important are the F-specific and somatic bacteriophages specific to E. coli. In our study examined them in a small municipal lake in Szczecin (Poland) in context of occurrence of F-specific and somatic bacteriophages specific to E. coli with used of SAL method. We proved that count of bacteriophages in this water tank is lower in context of different waters, but the relation between the amounts of this viruses and environments condition (air and water temperature) were similar to results observed in waters of seas, rivers and lakes.
Badania bakteriofagów wykazały, że w środowisku naturalnym znajdują się one głównie w wodzie, ale w małych jeziorach miejskich badano je sporadycznie. Poprzednie badania bakteriofagów w środowisku wodnym dotyczyły określania ilości i różnorodności oraz wykorzystywania ich jako wskaźników zanieczyszczenia wody. Wcześniejsze badania wykazały, że prawdopodobnie najważniejszymi są F-specyficzne i somatyczne bakteriofagi E. coli. W obecnym badaniu oznaczaliśmy je w małym jeziorze miejskim w Szczecinie (Polska), za pomocą metody SAL. Udowodniliśmy, że liczba bakteriofagów w tym zbiorniku jest mniejsza w porównaniu do innych wód, ale związek między liczbą tych wirusów a warunkami środowiska (temperatura powietrza i wody) był podobny do wyników obserwowanych w wodach mórz, rzek i jezior.
