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 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:
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...

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:
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.

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.

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.

Opis:
Subject and purpose of work: The article presents research aimed at creating the ranking of provinces due to the degree of environmental pollution. The presentation of the spatial distribution of pollutants should result in taking appropriate pro-ecological actions in the provinces. Materials and methods: Secondary material included in the research was the publication entitled “Environmental Protection – Environment 2017” by the Central Statistical Office. The method of ranking diagnostic variables was applied and then a synthetic variable determining the level of pollution in individual provinces was constructed, which made it possible to create their ranking. In the final stage, the author’s own method was implemented in order to divide the provinces into 3 groups. Results: The provinces were ranked from a relatively little to very polluted ones. Three groups of provinces were distinguished according to the criterion discussed. It has been revealed that the third group with the highest degree of environmental contamination includes as many as 8 provinces, that is half of them. Conclusions: The author believes that in order to prepare a more precise spatial diagnosis of the state of the natural environment in Poland, research has to be extended by including adequate information at the county level.
Przedmiot i cel pracy: W artykule przedstawiono badania mające na celu budowę rankingu województw ze względu na stopień zanieczyszczenia środowiska. Ukazanie przestrzennego rozkładu zanieczyszczeń skutkować winno podjęciem właściwych działań proekologicznych w przestrzeni województw. Materiały i metody: W badaniach wykorzystano materiały wtórne zamieszczone w wydawnictwie GUS „Ochrona Środowiska – Environment 2017”. Zastosowano metodę rangowania zmiennych diagnostycznych, a następnie skonstruowano zmienną syntetyczną określającą poziom zanieczyszczeń w poszczególnych województwach, co pozwoliło na budowę ich rankingu. W końcowym etapie wykorzystując metodę własną, dokonano podziału województw na 3 grupy. Wyniki: Ranking zawiera uporządkowane województwa od stosunkowo mało do bardzo zanieczyszczonych. Wyodrębniono 3 grupy województw ze względu na omawiane kryterium. Okazuje się, że do grupy III o najwyższym stopniu skażenia środowiska należy aż 8 województw, co stanowi połowę ich liczebności. Wnioski: Autor uważa, iż celem sporządzenia bardziej precyzyjnej przestrzennie diagnozy w zakresie stanu środowiska naturalnego w Polsce należy rozszerzyć badania poprzez uwzględnienie adekwatnych informacji na poziomie powiatów.

Introduction and objective. Many studies have indicated numerous nutrition mistakes among school-aged children and adolescents in both urban and rural environments. The aim of this study was to assess the nutritional habits of the Polish population, consisting of 7,974 individuals aged 12–17, from rural and urban environments, as well as to identify environmental variations of these habits and to verify the existing information on the incorrect nutrition of school-age children and adolescents. Materials and method. The research covered a group of 7,974 respondents – school-age adolescents with a similar age structure (12–17 years). The study on subjects from secondary school grades 1 – 3 was conducted in randomly selected schools from 2 random Polish provinces; 5 counties were randomly selected, followed by a choice of 2 communes: one rural and one urban. The research technique was a self-designed survey questionnaire. The obtained results were subjected to statistical analysis using the Pearson Chi 2 and V Cramer test. Results. The research revealed environment-based differences in subjects’ nutrition. Breakfast was consumed daily by a statistically significantly fewer subjects from the rural environment (36.31%) than from the urban areas (51.32%); second breakfast was consumed by an insignificantly smaller proportion of respondents from the urban environment (40.00%) than from the rural one (46.00%); dinner was eaten daily by 86.00% of urban subjects and 82.00% of rural respondents; afternoon tea and supper were eaten rarely by respondents from both environments. The diet of respondents was dominated by anti-health behaviours. Conclusions. Most of the respondents displayed incorrect nutritional behaviours. Nutritional mistakes occurred among respondents from both rural and urban environments, with the predominance of the rural areas.

Opis:
Hydroxylapatites are important biomaterials. Substitutions of Pb for Ca and As for P in hydroxylapatites are recently intensively studied due to their significance in the environmental immobilization of Pb and As (Lee et al. 2009, Chlebowska et al. 2015, Motyka et al. 2015). The general chemical formula of minerals in the apatite group is expressed by A 5 (XO 4 ) 3 Z, where A are bivalent cations (e.g., Ca 2+ or Pb 2+ , cations are distributed on two distinct crystallographic sites), XO 4 is a trivalent oxyanion (e.g., PO 4 3, AsO 4 3 - ), and Z is a monovalent anion (OH, F, Cl, or O). Positions Z and X may be partly filled with carbonate CO 3 2−. The structure of hydroxylapatite allows for unlimited substitutions of Pb 2+ for Ca 2+ and AsO 4 3− for PO 4 3−. The ability of lead and arsenic apatites to immobilize these toxic elements result from their high durability and low solubility at the conditions on the Earth surface. Various apatites possess different thermodynamic properties including different solubility in aqueous solutions but the systematic variation of these properties in solid solution series is poorly understood. The main objective of this research is determination of systematic variation in the solubilities of hydroxylapatites resulting from cationic substitutions of Pb 2+ for Ca 2+ and anionic substitutions of AsO 4 3− for PO 4 3− in their structure. Three solid solution series were synthesized: - HPY hydroxypyromorphite Pb 5 (PO 4 ) 3 OH – HAP hydroxyapatite Ca 5 (PO 4 ) 3 OH, HMi hydroxymimetite Pb 5 (AsO 4 ) 3 OH – JBM johnbaumite Ca 5 (AsO 4 ) 3 OH, - HAP hydroxyapatite Ca 5 (PO 4 ) 3 OH – JBM johnbaumite Ca 5 (AsO 4 ) 3 OH. The phases were synthesized from aqueous solutions at high pH above 8, at ambient temperature, by dropwise mixing of chemical reagents. The products are white, fine, homogeneous crystalline powders. Chemical composition determined by SEM/EDS is close to theoretical. X-ray diffraction confirms their crystalline structure and systematic changes in unit cell parameters with ionic substitution. Dissolution experiments were run in thermostatic bath at 25°C. An aliquot of 0.5 g of apatite was dissolved in 250 mL of 0.05M NH 4 NO 3 background solution at pH in the range of 3.5–5.0. Background solution was used to keep the ionic strength constant. The dissolution was carried out for 3 months. The bottles were manually stirred at least two times a week. The solution was syringe-sampled periodically and filtered through 0.2 μm polycarbonate filter to remove the suspended solids. The concentration of Pb and Ca was determined by atomic absorption spectroscopy. The concentration of dissolved phosphates and arsenates was determined by UV-vis colorimetry using a molybdenum blue method. The plateau on concentration evolution patterns from the dissolution experiments was observed to determine equilibrium in the suspensions. Dissolution of all the phases at the conditions of these experiments is incongruent. An increase in solution pH resulting from dissolution was observed in all cases. The system was considered in equilibrium when at least three consecutive samples showed identical concentration of Ca 2+ or AsO 4 3−. The equilibrium in HPY series was assumed by analogy. All the concentrations were recalculated to activities using PHREEQC model with Llnl database. The solubility K sp determined for the endmembers at 25°C conform with the literature data and equal to: HPY-K sp = 10 −7 7. 31 , HAP-K sp = 10 −55.66 , HMi-K sp = 10 −71. 56 , and JBM K sp = 10 −37.76. This confirms that, despite the incongruence of dissolution, the experimental procedure and the calculation scheme provide reliable approximation of the solubilities. The most soluble phase is johnbaumite Ca 5 (AsO 4 ) 3 OH. The solubility of all hydroxylapatites decreases linearly with the increase of Pb and P content. These trends do not correlate with the changes in Gibbs free energy of formation of the phases in question. This indicates that structural (e.g. the size of the ions) and the chemical factors (e.g. electronegativity) play the dominant role in the solubility of substituted hydroxylapatites.

Aim. The purpose of the research is to depict how talented students create their personal learning environment. The author of that paper shows a difference that has occurred thanks to the comparison between the manner in which average students and talented students build their personal learning environment. Methods. The author has conducted quantitative research, by making a survey. The surveys were carried out among fifty talented students. This paper focuses on the presentation of their opinions. The respondents presented how they constructed their personal learning environment. Additionally, they expressed their viewpoints about their digital competences. Results. The analysis shows that talented students are familiar with the latest digital tools. It allows them to design their personal learning space effectively. They can collect and process information profitably. They are also keen to share their knowledge with other participants of an educational process via the Internet, using some complex and practical devices. Moreover, talented students prefer discussing educational problems with other students online. They use some appropriate tools, such as chat rooms and social networking services. According to the research, the author can conclude that talented students are able to build and improve their digital learning space very well. They seem to create their personal learning environment functionally and consciously. Conclusions. Talented learners use advanced searching strategies, methods of collecting and storing information, and also teamwork tools. It is particular that they are autonomous learners but they also like sharing knowledge with other learners. The level of information competences of the talented students is quite high.
