Application Of Numerical Modeling In Quantitative Assessment Of BHT Dispersion In PE-HD Pipes
Authors: Musz Anna , Kowalska Beata 
Published: September 2015

Abstract
PE-HD water pipes are exposed to adverse environmental conditions, both during production and their subsequent use in the civil engineering. Several organic compounds migrating into water may lead to deterioration of water quality, especially its taste and odour. Commonly used antioxidant BHT and its products of degradation are leached into water as a result of degradation of the PE-HD pipes material. This paper presents the results of laboratory tests of BHT concentration changes in water circulating in the PE-HD close loop pipe of 30 m length as well as of numerical studies based on data obtained by the laboratory measurements. Numerical calculations were performed using the commercial software Fluent, Ansys Inc., based on the computational fluid dynamics (CFD) principles. The analysis of water samples confirmed the migration of the antioxidant from the pipe material into the water. The results of numerical analysis gave good agreement with the measured values.

Published: September 2015

Abstract
The study was conducted on an experiment established in the area of the former Sulphur Mine “Jeziorko.” The remediation was applied to a soil-less formation with particle size distribution of weakly loamy sand, strongly acidified and with bad sorptive properties (Corg. - 2.0 g kg−1; pHKCl - 4.3; T - 7.0 cmol(+) kg−1). In the particular treatments of the experiment the following were applied to the soil-less formation: flotation lime and NPK; lime and sewage sludge; sewage sludge; mineral wool (5 cm 50 cm−1), lime and NPK; mineral wool (5 cm 50 cm−1), lime and sewage sludge; mineral wool (500 m3 ha−1), lime and NPK; mineral wool (500 m3 ha−1), lime and sewage sludge. Plots prepared in that manner were then sown with a mix of grasses. The control was the soil with no amendments. The analyses of the soil material comprised assays of the numbers of particular groups of bacteria and fungi, and of their biochemical and enzymatic activities. The study revealed that all the wastes applied for the remediation caused an increase in the numbers of the bacterial groups studied (copiotrophic, oligotrophic, cellulolytic, lipolytic), as well as in the respiration activity and rate of mineralisation of cellulose. That effect was the most pronounced in the case of sewage sludge. In treatments in which sewage sludge was applied, an increase was also observed in the numbers of the studied fungi (fungi on Martin medium, cellulolytic fungi, lipolytic fungi) and in lipase activity. Whereas, the application of the remaining wastes resulted in a slight decrease in the numbers of the fungal groups under analysis. Comparing the mean annual values of the analysed biological, physical, chemical and physicochemical properties it was found that the biological properties were as sensitive, and in the case of certain tests (numbers of cellulolytic and lipolytic bacteria, rate of cellulose mineralisation) even more sensitive indicators of positive changes taking place in the remediated soil.

Abstract

Linnaea borealis, the twinflower, is considered a critically endangered species in the Południowopodlaska Lowland. The disappearance of the twinflower is mainly caused by habitat changes resulting from forest management, but also light deficiency due to the increase in canopy cover and growth of the shrub layer (processes of succession).
The aim of the paper is to present the actual distribution and phytosociological characteristics of L. borealis in the northern part of the Południowopodlaska Lowland. In this region, only three out of ten known areas of occurrence (Werchliś, Serpelice, Grala-Dąbrowizna) have endured to the present day. The twinflower occurs in pine forest, Peucedano-Pinetum, and mixed forest, Querco roboris-Pinetum, communities.
A decrease in the ground cover of twinflower populations was observed in all existing twinflower locations. Although the area covered by the Linnaea borealis population in Werchliś increased tenfold during the last 20 years (from about 200 m2 in 1993 to 1970 m2 in 2013), its cover-abundance according to the Braun-Blanquet scale decreased from 5 to 3. The increase in the area covered by the twinflower population together with the accompanying decrease in cover-abundance is probably not a manifestation of species dynamics but rather a response to disadvantageous environmental changes (growth of canopy cover and shrub layer). Progressive light reduction can initiate the process of fragmentation of a population.
A decrease in the cover-abundance of the L. borealis population (from 4 to 2) was also observed in Serpelice. Its area was reduced to half of its original size due to anthropogenic destruction of this location. In the third region, Grala-Dąbrowizna, also the negative effects of competitive species (e.g. Vaccinium myrtillus, V. vitis-idaea) are considered.

Abstract
The botanical composition of the European roe deer diet in the radioactively contaminated forest ecosystems of Zhytomirske Polesie of the Ukraine was investigated. Deer were caught monthly over a two–year period on three plots in forest habitats typical for Zhytomirske Polesie (fresh and moist mixed coniferous forests and mixed broadleaved forests). An analysis of the stomach contents of hunted deer showed that they consumed leafy as well as leafless stems, grasses, fruits and mushrooms depending on the season and availability of forest plants. Each season was characterized by one major dietary component. In the spring, the main component of the deer diet was the stems of woody plants. 44 species of vascular plants (3% of the natural flora of the region) were identified in the roe deer diet including 41 species of Magnoliophyta, of which 34 species of Magnoliopsida and 7 species of Liliopsida, 2 species of Polipodiophyta and one species of Pinophyta. Species such as aspen (Populus tremula), oak (Quercus robur), blackberry (Rubus nessensis) and bilberry (Vaccinium myrtillus) were consumed year-round.

Published: September 2015

Abstract
Wood-based panels made of waste and recycled raw material are lacking of dimensional stability. The aim of this study is to evaluate the potential beneficial effect of heat treatment (HT) on the properties of particleboards produced from waste of Pinus sp. used for packaging. The wood particles were heat treated at 180°C, 200°C and 220°C after grinding, and panels were produced with incorporation of 25%, 50%, 75% and 100% HT particles. The materials served as reference were particles without HT. Mass loss at 180°C and 200°C was small but increased significantly to 10.6% at 220°C. The HT caused a partial degradation of hemicelluloses, thereby the relative lignin content increased from 29.7% to 37.8% for the HT220°C samples. Thermogravimetry revealed higher thermal stability of the HT particles. The equilibrium moisture content decreased with HT, e.g. panels with HT220°C showed 30% lower compared to the reference. Swelling of the panels was lowered by 30% (panel with 75% HT material) compared to the reference. The results with HT pine were successful in terms of dimensional stability and lower hygroscopicity; however, the panels lost some strength properties.

Published: September 2015

Abstract
Because of its harmfulness to human health, asbestos has been banned in 55 countries, including the EU. In Poland, the use and production of asbestos and asbestos-containing products has been forbidden since 1997. However, there is no precise data about the amount of asbestos-containing products to be eliminated from the territory of Poland. This survey aims to identify characteristics that have a significant impact on the estimation of asbestos-containing products used in Poland. Statistical correlation between the results of the physical inventory count done in 155 municipalities was examined. As a result of the survey it was found that the amount of asbestos-cement roofing depends on the following factors: the number of individual farms in the village, the distance from the asbestos manufacturing plants, the age of the buildings and the economic situation of municipality. The results obtained may contribute to the ability to predict the amount of asbestos-containing products used in other municipalities.

Published: September 2015

Abstract
Highly conductive gallium-doped zinc oxide (GZO) transparent thin films were deposited on glass substrates by RF mag­netron sputtering. The deposited films were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), four-point probe and UV-Vis spectrophotometer, respectively. The effect of growth temperature on the structure and optoelectrical properties of the films was investigated. The results demonstrate that high quality GZO films oriented with their crystal­lographic c-axis perpendicular to the substrates are obtained. The structure and optoelectrical properties of the films are highly dependent on the growth temperature. It is found that with increasing growth temperature, the average visible transmittance of the deposited films is enhanced and the residual stress in the thin films is obviously relaxed. The GZO films deposited at the growth temperature of 400°C, which have the largest grain size (74.3 nm), the lowest electrical resistivity (1.31×10-3 Ω·cm) and the maximum figure of merit (1.46×1O-2Ω-1), exhibit the best optoelectrical properties. Furthermore, the optical proper­ties of the deposited films were determined by the optical characterization methods and the optical energy-gaps were evaluated by extrapolation method. A blue shift of the optical energy gap is observed with an increase in the growth temperature.

Published: September 2015

Abstract
A study has been conducted on the effects of partial, 10 % Co substitution by Fe in the perovskite Sr0.775Y0.225CoO3-δ compound. The XRD data show that the resulted samples of Fe-free and Fe-doped compounds exhibit good 314 single phase quality with a tetragonal I4/mmm crystal structure. The measured M-T curves display the typical feature of ferromagnetic (FM) transition at 335 K for the Fe-free sample, while showing significantly degraded FM ordering for the 10 % Fe-doped sample. The oxygen deficiency determined fro|m our 10 % Fe doped sample is found to decrease by only 0.025. Further detailed analysis of the XRD data also reveals distinctly different structural changes in the Co-O slabs compared to the 50 % Fe-doped sample which exhibits a complete suppression of FM order. The results of this study, thus, have revealed the close relations among the changes induced by Fe doping in the magnetic ordering of crystal, and its oxygen content as well as the associated local structure in the Co-O layers responsible for the magnetic properties in the compound.
Alcohol-Related Sickness Absence of Young Employees in Norway: The Impact of Social Roles and Socioeconomic Status
Authors: Schou Line , Birkelund Gunn Elisabeth 
Published: September 2015

Aims First, to establish whether there are differences in alcohol-related sickness absence according to socioeconomic status and family situation among young employees in Norway. Second, if differences are found, to assess whether they can be attributed mainly to differences in drinking patterns. Methods A sample of young, employed adults was obtained from the fourth wave of the Young in Norway study (2005) and the data were merged with registry data from Statistics Norway (N =1611). The data were analysed using cross tables and logistic regression analysis. Results Being male, single, not having children and having a low income were associated with alcohol-related sickness absence, but the association was not significant on education and social status. Introducing frequencies of drinking and drinking to intoxication in the regression model attenuated some associations with alcohol-related sickness absence. Conclusion Alcohol-related sickness absence is more common among people who are single and without children, and more common among men than women. With the exception of income, socioeconomic factors do not seem to be important. The differences between groups appear to be only partly a result of different drinking patterns.
Revising Whitehead’s Notion of Society in the Light of Contemporary Physics
Authors: Pugliese Marc A. 
Published: September 2015

AbstractThis article argues that Joseph A. Bracken’s revisions of Alfred North Whitehead’s derivative notion of “society” are plausible in view of developments in physics since Whitehead. In particular, Bracken argues that Whitehead’s derivative notion of “society” should rather be a category of existence equiprimordial with “actual entity,” and that contemporary actual entities in concrescence do influence each other as they directly prehend the society as a nexus. The article begins with Whitehead’s view of the metaphysical project as empirical, tentative, and subject to ongoing revision. Next, the essay explains Whitehead’s view of societies and contemporary actual entities. Following this is a survey of developments in physics since Whitehead that are relevant to his understanding of “society” and contemporary actual entities. The article then explains how Bracken differs from Whitehead on these points and argues that the physics developments corroborate Bracken’s proposed revisions to Whitehead. The essay ends with a restatement of Whitehead’s view of metaphysics as provisional and in need of ongoing revision.

Published: September 2015

Abstract
Bioremediation is the removal of heavy-metals such as nickel (Ni) using microorganisms and has been considered as an important field in the biotechnology. Isolation and characterization of microorganisms exhibiting bioremediation activities and their optimization to treat polluted wastewaters is a vital and difficult task in remediation technologies. In this study, investigation was carried out to isolate Ni (II) remediating microbial strains from soils contaminated with municipal solid waste leachate. Furthermore, Taguchi design of experiments were used to evaluate the influence of concentration, pH, temperature, and time on bioremediation of Ni (II) using isolated bacteria. This study concluded that Bacillus sp. KL1 is a Ni (II)-resistant strain and had Ni (II) bioremediation activity. The highest bioremediation of Ni (II) was observed as 55.06% after 24 h at 30ºC, pH 7, and 100 ppm concentration. Moreover, it was also observed that concentration is the most effective factor in the bioremediation process. In conclusion, we have demonstrated that bacteria isolated from soils contaminated with garbage leachate have the Bacillus sp. KL1 bacteria which can efficiently uptake and eliminate Ni (II) from contaminated sites and thus makes it possible to treat heavy-metal containing wastewaters in industry by using this microorganism at optimized conditions.

Authors: Ignaczak Wojciech , Wiśniewska Kinga , Janik Jolanta , Fray Mirosława El 
Published: September 2015

Abstract
A linear triblock copolymer, poly(styrene-b-etylene/butylene-b-styrene)(SEBS) thermoplastic elastomer (TPE) grafted with maleic anhydride was used for compatibilization of PP/PBT blends. PP/PBT blends of different mass ratios 60/40, 50/50, 40/60 were mixed with 2.5, 5.0 and 7.5 wt.% of SEBS copolymer in a twin screw extruder. Differential scanning calorimetry and dynamic mechanical analysis were performed to define the phase structure of PP/PBT blends. TPE with a rubbery mid-block shifted the glass transition of PP/PBT blend towards lower temperatures, and significant decrease the crystallization temperature of a crystalline phase of PP component was observed. The influence of the amount of compatibilizer and the blend composition on the mechanical properties (tensile and flexural strengths, toughness and moduli) was determined. Addition of 5 wt.% of a triblock TPE led to a three-fold increase of PP/PBT toughness. A significant increase of impact properties was observed for all materials compatibilized with the highest amount of SEBS copolymer.

Published: September 2015

Abstract
Removal of penicillin has been investigated using decaffeinated tea waste (DCTW). Decaffeination of tea waste was investigated using different methods. Results indicate that ozonation was the most effective process for removal of penicillin. Batch adsorption experiments were completed at various temperatures (20, 30, and 40°C), DCTW dosages (2, 4, 6, 8, and 10 g per 250 mL), penicillin concentrations (4, 10, and 14 mg/L), and pH (3, 7, and 10) conditions. Studies showed that adsorption reaches equilibrium within 40 min. The main factor affecting adsorption of penicillin was the solution pH, with maximum adsorption occurring at pH 3. Higher adsorbent dosages and lower penicillin concentrations also resulted in higher percentages of penicillin removal. Results show that data obeyed the pseudo-first-order kinetic and Freundlich isotherm models. This process proves that low-cost DCTW could be used as a high performance adsorbent for removing penicillin from aqueous solutions.
Hydrodynamics of Pilot Plant Scale Airlift Reactor in Presence of Alcohols
Authors: Nandi Somnath , Jaju Someshwar J. 
Published: September 2015

Abstract
The overall gas hold-up of a pilot plant scale internal loop airlift reactor was studied in presence of different alcohols in varied concentration. It has been observed that these simple alcohols can enhance overall gas hold-up of the airlift assembly possibly due to formation of protective thin layer over smaller gas bubbles thereby reducing chance of their coalescence. As the alcohols can be used as food source for the micro organisms present in the system, this green and environment friendly process have potential to replace usage of hazardous surfactants often used for enhancing overall hold-up in order to obtain desired mass transfer characteristics. An empirical relationship encompassing overall gas hold-up of the reactor as a function of superficial gas velocity and alcohol concentration is also developed.
Immunotoxin – a new treatment option in patients with relapsed and refractory Hodgkin lymphoma
Authors: Novakovic Barbara Jezersek 
Published: September 2015

Abstract

Background. Even though Hodgkin lymphoma is a highly curable disease, some of the patients have either a refractory disease or experience a relapse following a successful primary therapy. Durable responses and remissions in patients with relapsed or refractory disease may be achieved in approximately one-half with salvage chemotherapy followed by high dose chemotherapy (HDT) and autologous hematopoietic cell rescue (SCT). On the other hand, patients who relapse after HDT and autologous SCT or those who have failed at least two prior multi-agent chemotherapy regimens and are not candidates for HDT have limited treatment options.

Conclusions. A new treatment option in this population is an immunotoxin Brentuximab vedotin composed of a CD30 directed antibody linked to the antitubulin agent monomethyl auristatin E. It has demonstrated a substantial effectiveness and an acceptable toxicity. In the pivotal study, the overall response rate was 75% with 34% of complete remissions. The median durations of response were 20.5 and 6.7 months for those with complete remission and all responding patients, respectively. The median overall survival was 40.5 months (3-years overall survival 54%) and the median progression-free survival 9.3 months. The most common non-hematologic toxicities were peripheral sensory neuropathy, nausea, and fatigue while the most common severe side effects were neutropenia, thrombocytopenia, anemia, and peripheral sensory neuropathy.

A Model Dinosaur

Published: September 2015

This article explores the career of Rubén Figueroa, who, as governor of Guerrero, came to represent a classic regional boss during the latter part of the PRI regime. It examines how and why upwardly mobile actors built extensive personal networks and it offers a discussion of the nature of political power under the PRI. It advances three arguments: that effective networks were socially and spatially diverse, tying provincial aspirations to Mexico City’s corporatist politics; that these broad networks were important because of the regime’s particular metrics of “political strength;” and that this system articulated a distinctive power that linked capital and province.
Este artículo examina la carrera política de Rubén Figueroa, quien llegó a ser visto como un cacique típico durante el régimen del pri. Explorando por qué los aspirantes al poder construyeron redes personales y cómo esas redes fueron fundamentales para el poder priísta, se argumenta: que las redes que fueron efectivas eran diversas tanto en lo social como en lo espacial, y que ligaron las aspiraciones regionales a la política corporativista de la ciudad de México; que esas redes fueron importantes por la interpretación singular priísta de la “fuerza política”; y que esos entendimientos iluminan la naturaleza de poder político bajo el pri.
