Computational and Experimental Studies of UV/Titania Photocatalytic Oxidation of VOCs in Honeycomb Monoliths
Authors: Hall Robert J. , Bendfeldt Peggy , Obee Timothy N. , Sangiovanni Joseph J. 
Published: January 2017

AbstractThe use of honeycombs as monolith supports for UV/Titania photocatalysis of volatile organic compounds (VOCs) has been investigated theoretically and experimentally. A theoretical model based on analysis of the UV intensity distribution, transport of gaseous contaminants to the catalyzed surface, and surface photocatalytic destruction has been developed. Both diffuse and specular reflection models have been developed for the UV illumination calculations. The model uses measured intrinsic photocatalytic destruction rates determined in a research reactor which gives the concentration-, humidity-, and UV intensity-dependences of the rates. Model predictions have been compared to measurements in a high-flow, staged monolith, demonstration purifier for several gaseous contaminants of interest. Agreement between modeling and experiment is generally quite good. The sensitivity of purifier efficiency to monolith pore size and illuminated contact time is discussed. The performance obtained with honeycombs is comparable to that with porous foams, but with much reduced weight, pressure drop, and cost. The conclusion of this research is that honeycomb monoliths are attractive for use in practical UV/Titania photocatalytic devices, particularly at very high flow rates where pressure drop is a concern, and for those situations where monolith weight is an important design constraint.
TiO2-Mediated Photoelectrocatalytic Purification of Water
Authors: Candal Roberto J. , Zeltner Walter A. , Anderson Marc A. 
Published: January 2017

AbstractSol-gel processing methods were employed to coat thin, porous films of titania on metal plates, specifically on aluminum, 304 stainless steel, and titanium. After coating and firing, all of these materials displayed photocatalytic activity when tested with a solution of formic acid that contained dissolved sodium chloride. However, only the titanium-supported photoelectrodes were stable with repeated use. Activities of these titaniumsupported photoelectrodes increased, often by factors of two to three, when positive potentials were applied across the titania coatings. Electrode activities increased when multiple coatings of titania were applied to the electrodes, although electrode stability was problematic when multiple coatings were deposited. Photoelectrocatalytic activities were not inhibited significantly by the presence of sodium chloride in the test solutions, while copper could be deposited on platinum cathodes when the test solutions contained dissolved copper in addition to sodium chloride and formic acid.
Hypothetical, not Fictional Worlds
Authors: Weinert Friedel 
Published: January 2017

AbstractThis paper critically analyzes the fiction-view of scientific modeling, which exploits presumed analogies between literary fiction and model building in science. The basic idea is that in both fiction and scientific modeling fictional worlds are created. The paper argues that the fiction-view comes closest to certain scientific thought experiments, especially those involving demons in science and to literary movements like naturalism. But the paper concludes that the dissimilarities prevail over the similarities. The fiction-view fails to do justice to the plurality of model types used in science; it fails to realize that a function like idealization only makes sense in science because models, unlike works of fiction, can be de-idealized; it fails to distinguish sufficiently between the make-believe (fictional) worlds created in fiction and the hypothetical (as-if) worlds envisaged in models. Representation characterized in the fiction-view as a license to draw inferences does not sufficiently distinguish between inferences in fiction from inferences in scientific modeling. To highlight the contrast the paper proposes to explicate representation in terms of satisfaction of constraints.

Lifecycle Analysis of Different Motors from the Standpoint of Environmental Impact
Authors: Orlova S. , Rassõlkin A. , Kallaste A. , Vaimann T. , Belahcen A. 
Published: January 2017

Abstract
Comparative analysis is performed for different motors from the standpoint of damage inflicted by them during their lifecycle. Three types of motors have been considered: the synchronous reluctance motor, the permanent magnet assisted synchronous reluctance motor and the induction motor. The assessment of lifecycle has been made in terms of its four stages: manufacturing, distribution, use and end of life. The results show that the production costs of synchronous reluctance motor are lower compared to that of permanent magnet assisted motors, but due to their low efficiency they exert the greatest environmental impact. The main conclusion is that the assessment made at the early designing stage for the related environmental impact enables its reduction.
Where can flood refugees go? Re-distribution of Corncrakes (Crex crex) due to floods and its consequences on grassland conservation in North-Eastern Hungary

Published: January 2017

Abstract
The Corncrake is a threatened umbrella species for wet meadows, which mostly depends on managed grasslands. Therefore, effective conservation requires bird-friendly land management schemes and subsidies. Although the most important populations in Hungary usually breed in protected areas, some of these are regularly flooded, which forces Corncrakes to find breeding sites elsewhere. Such movements from protected/subsidised areas to suboptimal sites have risks for Corncrake populations and their conservation. Here, we describe a large-scale dynamic system of interlinked populations based on data from 4194 Corncrake territories found at four different sites (Aggtelek, Bodrogzug, Szatmár-Bereg and Zemplén regions) across eight years between 1997 and 2006 in NE Hungary (c. 1500 km2). The results showed that the total population fluctuated between 407 and 631 pairs and that the populations were more-or-less stable in the first four years (1997–2000). However, extended floods caused the disappearance of the species from the Bodrogzug region in 2005–2006, while in the other sites, the number of territories increased five-fold (Zemplén), three-fold (Aggtelek) and two-fold (Szatmár-Bereg). The correlation between the number of territories and maximum water level of river Tisza in April-May was negative in the Bodrogzug site and positive in the three other sites, indicating that interlinkages of the populations were associated with water levels. Our data thus support the hypothesis that many of the birds driven out by inundation of floodplain meadows moved to other sites in NE Hungary in flood years. These results suggest that even large, centrally located populations of Corncrake can be greatly exposed to risks of flooding and that it is highly important to maintain suitable alternative breeding sites for the species. The High Natural Value Areas programme may allow administrative and funding support to provide or extend protection and/or subsidies to maintain this large-scale dynamic system. To this end, the area managed in bird-friendly ways and subsidised under agri-environmental schemes was extended by 35,000 hectares in NE Hungary in 2009.

Published: January 2017

Abstract
The subject of this study focuses on the cranial morphology of 24 native European passerine bird families. In addition to the discussion of taxonomical questions regarding to the examination of beak, orbit, cranium and mandible, the author aims to provide guidance to the determination of raptors’ prey remains. Most of the studied bird families are well-distinguishable using the knowledge on the mentioned osteological traits except some less-specialised families.
Attempts to increase a scarce peripheral population of the Red-breasted Flycatcher (Ficedula parva) using a new type of nestbox
Authors: Deme Tamás 
Published: January 2017

Abstract
The Red-breasted Flycatcher has a large and stable global population widespread through much of the Western Palearctic. Contrarily, however, it is a very scarce breeding bird in the forested montane habitats of Hungary. The few pairs breeding here represent a peripheral population on the very edge of the species’ geographic area. This peripheral population declined considerably (from 3–500 to 100 pairs) during the past decades likely due to the degradation of suitable habitat patches including the loss of appropriate nesting sites. To reverse this trend, we applied a new type of artificial nestbox developed specifically for this species. Occupancy rate was very low and breeding success was also low unless applying a protective wire mesh to reduce predation pressure.

Published: January 2017

Abstract
The present paper acts as an introduction to a series that will describe the exploratory analyses of migration phenology and morphometrics of the most common passerine species at the Ócsa Bird Ringing Station. This station is situated in the Ócsa Landscape Protection Area that belongs to the Duna–Ipoly National Park, Hungary. The area is somewhat cooler and more humid than the surrounding agricultural fields and tree plantations, covered by a mosaic of diverse hygrophilous vegetation patches. Bird trapping is mostly based on Japanese mist-net lines crossing different plant communities. During the period of 1984–2015, a total of 422,862 birds were trapped and ringed here, while 202,739 local, 1,235 within country, and 443 foreign recaptures were also recorded. Each bird is characterized by the following data: location and time of capture, species, age, sex, scores of fat, pectoral muscle, wing tip abrasion, and moult, length of wing, 3rd primary, and tail, and body mass. After subjected to a rigorous quality check, digital data are deposited in the archive of the Hungarian Bird Ringing Centre, and the EURING data base. From time to time, other research projects also utilized the accessibility of wild birds captured here, thus collection of blood samples, ecto- and endoparasites was carried out at the station. The relatively long time span, large number of species and individuals, and the readily available environmental (weather, vegetation, etc.) data makes the avian data collected here a suitable base for studies of various disciplines like capture methodology, habitat preferences, breeding, migration, and wintering, effects of weather and climate change, and epidemiology of viruses and parasites.

Published: January 2017

Abstract
Ornithological studies often rely on large temporal scale ringing datasets as source of information. However, basic descriptive statistics of collected data are rarely provided. In order to fill this gap, here we present the first item of a series of exploratory analyses of migration timing and body size measurements of the most frequent Passerine species at a ringing station located in Central Hungary (1984–2015). First, we give a concise description of foreign ring recoveries of the Pied Flycatcher in relation to Hungary. We then shift focus to data of 2860 individuals deriving from the ringing station, where birds have been trapped, handled and ringed with standardized methodology since 1984. Timing is described through annual and daily capture and recapture frequencies and their descriptive statistics. We show annual mean arrival dates within the study period and we present the cumulative distribution of first captures with stopover durations. We present the distributions of wing, third primary, tail length and body mass, and the annual means of these variables. Furthermore, we show the distribution of individual fat and muscle scores, and the distribution of body mass within each fat score category. We distinguish migration periods (spring and autumn), age (i.e. juveniles and adults) and sex groups. Our aim is to provide a comprehensive overview of the analysed variables. However, we do not aim to interpret the obtained results, merely draw attention to interesting patterns, that may be worth exploring in detail. Data used here are available upon request for further analyses.
Project ambidexterity: case of recovering schedule delay in a brownfield airport project in India
Authors: Iyer K. Chandrashekhar , Banerjee Partha S. 
Published: January 2017

AbstractPlanning deficiencies and consequent execution delays are likely to persist in infrastructure development projects. However, recovery of schedule delay is a less researched area. This case research, using a two-stage inquiry modeled on the grounded theory, studied the schedule delay recovery during the execution phase of a brownfield airport construction project. The analyses generated contextual evidence and ambidexterity was found to be the key underlying phenomenon for successful recovery measures. The empirical learning was validated with literature and can be used by practitioners looking to institute schedule recovery measures.

Published: January 2017

Abstract
Cost optimization in health care is based on starting enterprises that employ workers who, after full-time work, perform the same or similar activities for the employer. This violates the social security legislation and creates both legal and financial risks. Using the current regulations, as well as Supreme Court rulings and opinions contained in the publications, the present paper analyzes the legal aspects regarding the phenomenon observed in the labor market.

Published: January 2017

Abstract

Introduction. In Poland, among patients coming to hospital emergency departments (ED), one third require immediate surgical treatment. About one third are transferred to long-term intensive care. The remaining patients require a different type of care, e.g. consultation, healing wounds, observation in the emergency department. From there, they might either be referred to another hospital department or sent home after receiving outpatient help.

Aim. The aim of this study was to determine the prevalence of pain and stress in patients treated in the emergency department with particular emphasis on the factors that determine their level.

Material and methods. The study group consisted of 200 individuals treated in the emergency department of the Regional Hospital No. 2 in Rzeszów in 2013. The applied research method was a diagnostic survey that used a questionnaire as a research tool. The results were statistically analyzed using SPSS 20, whereas a statistically significant dependence was considered in those with level of significance p≤0.05.

Results. Most respondents reported pain and feelings of stress while staying in the ED. Women and the unemployed were significantly less likely to report pain. Factors like gender, age, education level, and the coexistence of chronic diseases significantly affected the degree of stress among patients in the ED.

Conclusion. Each patient treated at the emergency department should receive holistic care, so that the pain and stress of his injuries are reduced as soon as possible.

Authors: Cichocka Izabela , Krupa Jan 
Published: January 2017

Abstract

Introduction. The interest in weight loss supplements can be noticed in Poland at the moment. It is related to people’s trying to look good as fast as possible. The pharmaceutical market puts an emphasis only on the benefits and majority of the people purchasing the supplements do not regard doctor’s advice as necessary. Therefore, in order to learn about consumers’ awareness about the use of dietary supplements is gaining importance.

Aim. The objective of the study was to gain knowledge about choice preferences of dietary supplements used in weight loss, like also to learn about consumer’s awareness about the use of dietary supplements.

Material and methods. An anonymous survey was conducted in Mielec in 2015 among 112 women. The questionnaire included questions concerning their knowledge of dietary supplements, the type and amount of consumption, the reasons for using supplements, benefits and health risks of their use.

Results. 90.2% of women admitted that they are using or they used dietary supplements in order to reduce weight. Respondents most often derive the information about these preparations from the pharmacist (62.5%), television (46.4%), a doctor (36.6%), radio (30.4%), the Internet (29.5%). 72.4% of female respondents pay attention to the composition of dietary supplement, with the emphasis on the amount of the ingredients (64.3%), its dosage (55.4%), the origin of the ingredients (natural or synthetic) (37.5%). Female respondents prefer dietary supplements either in the form of tablets (83.9%) and capsules (54.7%), as well as in liquid (52.7%).

Conclusions. Respondents showed an increased interest in supplements used for weight loss and they usually use it in forms of tablets and capsules. As the role of the Internet increases, it is necessary to educate consumers about ability to search reliable sources of information about dietary supplements used for weight loss.

Abstract

Introduction. HPV infection is one of the most common type of sexually transmitted infections and it is a significant epidemiological problem all over the world. The risk of infection persistence and its progression to pathological, precancerous lesions depends on HPV type. Vaccinations against HPV virus are one of the elements of the prophylactic program and allow for early detection of cervical cancer.

Aim. Aim of the study was analysis of awareness of problems of human papillomavirus infections and cervical cancer prevention, including vaccinations against HPV among female students commencing studies in Lublin.

Material and methods. The research group included 400 women selected at random, all starting their studies at five universities in Lublin. The research group was supposed to show some general knowledge of the problem of cervical cancer among young women. It was also to define how many of them benefited from the prophylaxis of getting a vaccination against HPV. The scientific tool was individually elaborated survey questionnaire. Obtained study results were then subject to statistical analysis.

Results. The majority of respondents were not vaccinated against HPV – only 2.5% of the surveyed confirmed that they had been vaccinated. The surveyed students most frequently evaluated their knowledge on prevention of HPV cervical cancer as poor. The surveyed who admitted having information about HPV and cervical cancer prophylaxis during their classes at school significantly more frequently had high level of knowledge than women who claimed not to obtain such information at school (p=0.002).

Conclusions. It might make sense to conduct planned comparative studies in the centers practicing population vaccinations among girls aged 12-13 and not practicing such primary prophylaxis with cytological follow-ups. It may allow to elaborate the effective model of cervical cancer prophylaxis based on early educational activities, both on primary and secondary prophylaxis.

Abstract

Introduction. Chronic pancreatitis is morphologically characterized by ductal dysplasia, breeding grounds for the proliferation of the ductal cells, the degenerative changes in pancreatic acinar cells and fibrosis, and it is defined on the basis of the clinical, morphological and functional criteria.

Aim. The aim of our study is to examine the existence of a possible correlation between the iNOS-2087A>G polymorphism and chronic pancreatitis by means of the genetic analysis.

Material and method. We have conducted the study at the Gastroenterology Clinic and the Research Center of Gastroenterology and Hepatology of the University of Medicine and Pharmacy, Craiova, between March 2015 – September 2016. The study had a prospective character. Both for the 58 patients diagnosed with chronic pancreatitis and for the 132 patients in the witness group, the biological material was represented by blood, (around 2.5 – 5 milliliters of venous blood) let on EDTA and kept at 4°C up to the separation of the DNA molecule. All the patients were genotyped for the iNOS – 2087A>G polymorphism, by means of the Real Time PCR technique with TaqMan probes.

Results. Analysing the prevalence of the iNOS genotypes within the study group and witness group, we have noticed that, statistically speaking, there are no significant differences between the two groups.

Conclusion. As a conclusion, in the study lot we can sustain that the risk of developing chronic pancreatitis is not increased by the presence of the iNOS-2087A>G polymorphism.
