Published: March 2014

ABSTRACT In this study, we assessed the feasibility of fetal RhD genotyping by analysis of cell-free fetal DNA(cffDNA) extracted from plasma samples of Rhesus (Rh) D-negative pregnant women by using real-time polymerase chain reaction (PCR). Fetal genotyping was performed on 30 RhD-negative women between 9 and 39 weeks of gestation who were referred to us for invasive testing [amniocentesis/ chorionic villi sampling (CVS)]. The fetal RHD genotype was determined based on real-time PCR method. Exons 7 and 10 of the RHD and SRY genes were targeted. Among the pregnant women, 12 were carrying male and 17 were carrying female fetuses. Out of 29 pregnant women, 21 had RhD-positive and nine had RhD-negative fetuses. One sample )case 12, whose blood group was found to be AB Rh [+] (was excluded due to controversial results from repeated serological analyses. All prenatal results were in concordance with postnatal RhD status and fetal sex without false- positive or -negative results. Performing real-time PCR on cffDNA showed accurate, efficient and reliable results, allowing rapid and high throughput non invasive determination of fetal sex and RhD status in clinical samples.

Published: March 2014

Abstract
We study a special two-stage flexible flowshop, which consists of several parallel identical machines in the first stage and a single machine in the second stage. We assume identical jobs, and the option of batching, with a required setup time prior to the processing of a new batch. We also consider the option to use only a subset of the available machines. The objective is minimum makespan. A unique optimal solution is introduced, containing the optimal number of machines to be used, the sequence of batch sizes, and the batch schedule. The running time of our proposed solution algorithm is independent of the number of jobs, and linear in the number of machines
Revascularization of immature non-vital permanent teeth - literature review and a case study
Authors: Tarpomanov Yordan D. , Kukleva Maria P. 
Published: March 2014

ABSTRACT
Apical periodontitis in permanent children’s teeth with incomplete root development is a challenge for endodontists to treat. It is important that highly efficient therapeutic methods and biologically valuable therapies be developed to prevent the loss of these teeth. The AIM of the study was to review modern literature on revascularization of non-vital permanent teeth with incomplete root development, and to present a clinical case. The literature review herein reflects the modern concept of revascularization of non-vital permanent teeth with incomplete root development. Clinical protocols are presented on cases with and without the formation of a blood clot. The case study reports the treatment of an immature non-vital permanent tooth using the technique of revascularization that utilises formation of a blood clot and use of a two-component antibiotic paste for disinfection. One year after treatment the clinical and radiological data showed absence of subjective complaints, thickening of the root walls, apical closure and no periapical pathology of the revascularized tooth. Literature data and the favorable outcome of our case allow us to further research the revascularization of immature non-vital permanent teeth.
Validation of the Bulgarian version of scales for outcomes in Parkinson’s disease – autonomic (SCOPA-AUT-BG)
Authors: Mantarova Stefka G. , Velcheva Irena V. , Georgieva Spaska O. , Stambolieva Katerina I. 
Published: March 2014

ABSTRACT
The last twenty years have witnessed a surge of interest in the autonomic symptoms in Parkinson’s disease (PD) and the possibilities to diagnose and treat them. The specialized questionnaire assessing the autonomic symptoms in Parkinson’s disease (SCOPA-AUT) has been validated and available in English, Dutch and Spanish. In this study we aim at evaluating the validity, reliability and applicability of the Bulgarian version of SCOPAAUT (SCOPA-AUT-BG ).
PATIENTS AND METHODS: The study included 55 patients with idiopathic PD (mean age 64.4 ± 8.9 yrs), and 40 healthy controls (mean age 58.5 ± 9.4 yrs). Clinical severity and disease stage were assessed by United Parkinson’s disease rating scale (UPRDS) and Hoen and Yahr (H&Y). Thirty-two of the PD patients completed SCOPA-AUT-BG again after a 7-day interval. Questionnaire reliability was analyzed by determining the internal consistency, homogeneity, discriminatory and construct validity and test-retest reliability.
RESULTS: Analyses showed good internal consistency of the summary evaluation of SCOPAAUT- BG (coefficient alpha of Cronbach = 0.79), which indicates the high reliability of the questionnaire. The lowest Cronbach’s alpha coefficient (0.53) was found for the subscale “cardiovascular functions”. A dominant role belongs to the subscales for gastrointestinal and urinary functions (Cronbach’s Alpha > 0.7), where a significantly high correlation of PD with the UPDRS scale was observed. We found high test-retest reliability based on the responses associated with dysfunction of the gastrointestinal, urinary, thermoregulatory and pupillary autonomic systems. The correlation of the results of SCOPA-AUT-BG with UPDRS is higher than that with H&Y, and the construct validity is high except for the cardiovascular and pupillomotor functions subscales.
CONCLUSION: The results of this study show that SCOPA-AUT-BG is a valid and reliable specialized questionnaire to evaluate autonomic function in patients with Parkinson’s disease. Using it allows for more detailed clinical evaluation of these patients and justifies the need to refer them to specialized examination of autonomic functions.
Protective effect of aronia melanocarpa fruit juice in a model of cisplatin-induced cytotoxicity in vitro
Authors: Valcheva-Kuzmanova Stefka V. , Beronova Anna B. , Momekov Georgi Tz. 
Published: March 2014

ABSTRACT
AIM: The aim of the present study was to investigate the protective potential of Aronia melanocarpa fruit juice in a model of cisplatin-induced cytotoxicity in the human embryonal kidney cell line HEK293T.
MATERIALS AND METHODS: The cellular viability was assessed using the MTT-dye reduction assay based on the reduction of the yellow tetrazolium dye MTT to a violet formazan product via the mitochondrial succinate dehydrogenase in viable cells. Cisplatin was applied in various concentrations either alone or after a 24-hour pretreatment of the cells with Aronia melanocarpa fruit juice at 0.1 and 0.05 mg/ml. The half maximal inhibitory concentrations (IC50 values) were derived from the concentration-response curves to cisplatin.
RESULTS: Applied alone, the anticancer drug caused a prominent decrease of cellular viability with IC50 8.3 ± 1.1 μM. The juice proved to significantly ameliorate the in vitro cytotoxicity of the platinum drug, in a concentration-dependent manner. The pretreatment of the cells with Aronia melanocarpa fruit juice resulted in a significant increase (p < 0.001) of IC50 for cisplatin to 25.1 ± 2.7 μM (at 0.05 mg/ml) and 34.4 ± 3.4 μM (at 0.1 mg/ml), respectively.
CONCLUSION: The protective effect of Aronia melanocarpa fruit juice observed in this study is most probably due to its well appreciated antioxidant activity as oxidative stress plays a central role in the toxic effects of cisplatin.
Anthropogenic mineral deposits in Wielkopolska lignite mines – current state of research

Streszczenie
W pracy tej przedstawiono aktualny stan badań, twrorzenia i wykorzystania złóż antropoge- nicznych w dwóch istniejących wielkopolskich kopalniach węgla brunatnego, tj. PAK KWB Konin SA. i PAK KWB Adamów S.A. Oczywiście w złożach antropogenicznych składowano tzw. kopaliny towarzyszące, które wydobyto przy okazji eksploatacji węgla brunatnego będącego kopaliną główną. Badaniom poddano tylko tc złoża antropogeniczne, w których zgromadzono kopaliny w ilości wyrażonej w tysiącach metrów' sześciennych. W kopalni Konin są to następujące złoża antropo- geniczne: Honoratka, Kleczew i Bilczcw. W złożu Honoratka odłożono ncogcńskic iły i piaski, a w złożu Kleczew wyłącznic ncogcńskic iły. Kopaliny z obu wymienionych złóż służą do produkcji ceramiki budowlanej w cegielni „Honoratka-Wicncrbcrgcr”. Z kolei w złożu Bilczcw odłożono czwartorzędowe piaski, które obecnie nic są wykorzystywane. W przypadku kopalni Adamów można mówić o dwóch małych złożach antropogenicznych, tj. Janiszcw' i Władysławów. W złożu Janiszcw znajdują się iły ncogcńskic, któro do 2007 roku wykorzystywała cegielnia w Wiclcninic. Natomiast w' złożu Władysławów odłożono czwartorzędowe piaski i żwiry. W czasie prowadzenia badań terenowych, w'c wrześniu 2012 roku, złoże to było eksploatowane. Łącznic w' złożach antropogenicz- nych w kopalni Konin znajduje się ponad 3,36 min m3 iłów i 0,64 min m3 piasków ncogcńskich, a także 0,7 min m3 piasków czwartorzędowych. Natomiast w kopalni Adamów, w sąsiedztwie odkrywek, zgromadzono ponad 18 tys. m3 iłów' ncogcńskich i mniej niż 12 tys. m3 czwartorzędowych piasków i żwirów. Dlatego ze względu na duże zasoby kopalin tow'arzyszących zaleca się tworzenie złóż antropogenicznych przez kopalnie węgla brunatnego. Niemniej jednak powinien zostać uregu- lowany ich status prawny oraz stworzone odpowiednie zachęty finansowe.

Przeprowadzono datowania za pomocą metody trakowej i helowej dla apatytów z utworów karbońskich w Górnośląskim Zagłębiu Węglowym w celu określenia ram czasowych procesów uwęglcnia. Pomierzone centralne wieki trakowe apatytów mieszczą się w przedziale od 259±11 (późny perm) do 103±6 milionów lat (wczesna kreda), a średnia długość traków waha się od 11,7±0,2 do 13,7±0,1 (im. Wszystkie wieki trakowe są młodsze od wieku stratygraficznego analizowanych próbek, wskazując znaczne zaawansowanie procesów diagcnctycznych. Próbki z zachodniej i środ- kowej części GZW mają wieki trakowe od późnego permu do środkowego/późnego triasu (259±11 do 214±10 min lat). Jcdnomodalnc rozkłady długości traków i ich średnie wartości wskazują na poje- dyncze, względnie szybkie zdarzenie postwaryscyjskicgo wychładzania do temperatury poniżej 60°C, co jest zgodne zc znaczną erozją postinwersyjną utworów gómokarbońskich po fazie asturyjskicj. W pozostałej części mczozoiku następowało wolniejsze wychładzanie. Próbki zc wschodniej i NE części GZW mają wieki trakowe od późnego triasu do wczesnej kredy (210±10 do 103±6 milionów lat). Charakteryzuje je względnie krótsza średnia długość traków i wyższe odchylenia standardowe, a także w przypadku części próbek bimodalny i/lub mieszany charakter rozkładów długości. Jest to razem wskazówką bardziej złożonej historii termicznej, z długim okresem przebywania w PAZ i możliwym drugim zdarzeniem termicznym. Wieki helowe apatytów w całym basenie są wczcs- nokredowc(144,l±l 1 do 108,1±8 milionów lat), wskazując raczej na wolne postwaryscyjskic wychła- dzanie lub możliwe mczozoicznc podgrzanie karbonu do temperatury nic większej niż 60-70°C, które spowodowało częściową dyfuzję helu i odmłodzenie wieków helowych, ale równocześnie nic spo- wodowało znaczącego zabliźniania traków na większości obszaru GZW. Jedynie w NE części GZW podgrzanie mczozoicznc mogło być nieco wyższe, do temperatury 70-85°C, powodując odmłodzenie wieków trakowych, zwłaszcza przy długim okresie przebywania w PAZ. Mczozoiczny impuls ter- miczny był przypuszczalnie spowodowany cyrkulacją gorących roztworów związaną z procesami ekstensji. Powyższe zakresy temperatur i czas ich występowania świadczą, żc uwęglenie materii organicznej w GZW nastąpiło zasadniczo z końcem okresu karbońskiego.
Clearing the path that has been laid: a conceptualisation of education for sustainable development
Authors: Bentham Hayley 
Published: March 2014

Abstract
Education for sustainable development (ESD) has become so crucial that we have tried to smear it on anything and everything that's teachable. The consequence is that almost everything we do may be said to contain weak attributes of ESD even if we know nothing significant about it. This paper attempts to reveal an understanding of ESD that is informed by an exploration of policy language and agenda and recent literature in the field. The exploration of policy reveals the possible cause for previous inadequate implementation of ESD. An exploration of policy and literature reveals some key competencies that are advocated for through ESD. Insight into how policy has shifted from an ecological to a development focus and substantiation for why this shift is important in addressing current sustainable development issues serves to inform the interpretation of ESD. Finally, the analysis of policy and literature is triangulated to develop a framework that may assist ESD stakeholders in identifying ESD competencies in policy and practice. It is hoped that through this engagement with selected texts a more informed and complex insight into ESD and its features may be developed

The paper provides an insight into the results of a lesson designed and carried out at Riga Construction College in the study subject "Building Constructions". The aim of this study is to better understand the impact of learning environment reorganisation into juvenile groups while teaching technical study subjects. In particular, the research conducted at this vocational secondary school focused upon introducing a particular form of integrative collaboration amongst the learners. Criteria were developed to respond to the question: How is the organisation of the learning process based on the Learners' Integrative Collaboration Model changing? A formative teaching experiment, which analyses learners' integrative collaboration through structured observation at the beginning and end of the acquisition of the study subject "Building Constructions" points at positive changes associated with the model's criteria: working in a team, mutual learning, business communication and creativity action
Education for sustainable development in early childhood education in Finland
Authors: Reunamo Jyrki , Suomela Liisa 
Published: March 2014

Abstract
In the Finnish early childhood education and care (ECEC) curriculum, there is no specific content for education for sustainable development (ESD). Thus, it is not possible to get direct guidelines on how to conduct ESD in ECEC from the curriculum. We seek to look at the preferences of Finnish early childhood educators through the model of extended environmental education. Behind this model is Palmer's tree model and an emphasis on empirical, social and ethical components of ECEC. The research method employed a survey. Altogether 924 teams in Southern Finland evaluated their learning environments. By using a factor and reliability analysis, we extracted three factors relevant to the extended Palmer's model. The teachers primarily emphasised the understanding (learning) aspects of ECEC. The second most important aspect comprised the social aspects of education. The third most important aspect included the ethical and participant aspects of ECEC. Potential implications and indications to the practice of ESD are discussed
Analysis of evapotranspiration in the catchment of the Nurzec River, Poland using MODIS data
Authors: Ślązek Mateusz 
Published: March 2014

Abstract
The objective of this study is to analyse the spatial diversity and temporal variation of evapotranspiration in the catchment of the Nurzec River in the years 2001-2010. The study is based on MODIS images highlighting monthly accumulated values of evapotranspiration, Normalized Difference Vegetation Index (NDVI), and land use categories. Monthly evapotranspiration was calculated for the whole catchment as well as in different land use categories. The study focuses on assessing the relationship between the values of NDVI and evapotranspiration. The annual ET according to MODIS varied from 392 mm to 458 mm. Deciduous broadleaf forests have a higher ET than other land use categories. The analysis shows a strong correlation between monthly ET and NDVI.
Key Components of Musical Discourse Analysis
Authors: Aleshinskaya Evgeniya 
Published: March 2014

Abstract
Musical discourse analysis is an interdisciplinary study which is incomplete without consideration of relevant social, linguistic, psychological, visual, gestural, ritual, technical, historical and musicological aspects. In the framework of Critical Discourse Analysis, musical discourse can be interpreted as social practice: it refers to specific means of representing specific aspects of the social (musical) sphere. The article introduces a general view of contemporary musical discourse, and analyses genres from the point of ‘semiosis’, ‘social agents’, ‘social relations’, ‘social context’, and ‘text’. These components of musical discourse analysis, in their various aspects and combinations, should help thoroughly examine the context of contemporary musical art, and determine linguistic features specific to different genres of musical discourse.

Authors: Awad Simon , Rząd Izabella , Busse Przemysław 
Published: March 2014

ABSTRACT
A new research project near Jericho in the Jordan Valley (Palestine) was launched on 10 September 2013, work continued until October 23rd 2013. Standard ornithological work and bird ringing work was conducted using mist nets situated in an oasis type habitat of Wadi Qelt surrounded by palm plantations. The field methods followed the SEEN (SE European Bird Migration Network) standards that include apart from ringing of captured birds, also several measurements (wing length, tail length, wing formula) and scores (fat load and body mass), as well as the studies on the directional preferences of migrants using round, flat orientation cages. Ornithological research was enhanced by parasitological studies analysing migratory birds (hosts) - helminths relations during migration period of the former. This was a part of complex studies covering the Middle East and north African ringing sites. Altogether 481 individuals of birds representing 59 species were ringed and about 50 were retrapped. The most interesting was relatively high share of Masked and Red-backed shrikes as well as good number of birds of local species as Dead Sea Sparrows and introduced Indian Silverbills.
Unusual potassium-oxalate coordination in the two-dimensional trimetallic [CoCl(NH3)5][KCr(C2O4)3]·0.5H2O complex
Authors: Wrzeszcz Grzegorz , Wojtczak Andrzej , Zawadzka Magdalena 
Published: March 2014

Abstract
A new heterometallic compound, [CoCl(NH3)5][KCr(C2O4)3]·0.5H2O (1), has been synthesized and characterized by elemental analysis, IR and electronic spectra, thermal analysis, variable temperature magnetic susceptibility measurements, and single crystal X-ray diffraction. Compound 1 consists of two-dimensional [{KCr(C2O4)3}n]2n− layers, [CoCl(NH3)5]2+ ions and water molecules. Within the 2-D layer, three different types of oxalate coordination modes are present. Each K cation is coordinated by eight oxygen atoms from oxalate groups and also weakly interacts with the ninth oxygen atom. The extensive network of hydrogen bond is formed between the [KCr(C2O4)3]2− layer and the [CoCl(NH3)5]2+ ions. These interactions involve all hydrogen atoms of ammonia ligads and water molecule.
Geochemical investigation of alluvial sediments: validation of ICP-OES determination of heavy metals. A case study from the Utrata River Valley (central Poland)
Authors: Biro Miša , Kavšek Darja , Karasiński Jakub , Szwarczewski Piotr , Bulska Ewa , Vončina Darinka 
Published: March 2014

Abstract
The development and validation of a reliable analytical procedure for the determination of selected metals (Cd, Cr, Cu, Pb, Zn and Mn) in sediments accumulated in the Utrata River (Poland) is described. The aqua regia extraction followed by inductively coupled plasma optical emission spectrometry (ICP-OES) was used for this purpose. The optimized analytical procedure was validated, and adequate quality control actions were implemented in order to provide reliable data. The precision under’ within-laboratory’ reproducibility conditions was estimated from duplicate analysis. Certified reference material (CRM) was used in order to evaluate the accuracy of the results regarding the sewage sludge amended soil CRM 143R. The detection limits for all elements of interest were well-below their content in the investigated sediment samples. The obtained reliable data could be used for assessment of the relationship between human economic activity in the past and the geochemical features of the sediments.

Abstract
The aim of this research was to investigate the chemical composition of Coreopsis tinctoria Nutt. fruits extract, to highlight the potential of ultrasound assisted extraction in the fast preparation of extracts rich in polyphenols using different solvents (55%, 78% and 96% hydrous ethanol) and to evaluate the antioxidant potential of formulated extracts. LC-MS/MS was used to characterize the ethanolic extract from Coreopsis tinctoria Nutt. dried fruits. The extract contains different flavonoids (marein, flavanomarein, quercetagetin-7-O-glucoside, okanin aurone, leptosidin, luteolin, apigenin) and phenolic acids (chlorogenic acid, caffeic acid). Several parameters that could affect extraction efficiency were evaluated. Finally, this study focused on determination of plant extracts total phenolic content and their antioxidant capacity. The experimental results allowed the selection of the optimum operating parameters leading to the highest total polyphenolic content, expressed as gallic acid equivalents, and avoiding the degradation of phenolic compounds (ethanol 55%; extraction temperature 323.15 K, extraction time 30 min, liquid/solid ratio 20/1). A good relationship between total phenolic content and antioxidant capacity was obtained.

Abstract
For a sequence x ∈ l
1\c
00, one can consider the achievement set E(x) of all subsums of series Σn=1∞
x(n). It is known that E(x) has one of the following structures: a finite union of closed intervals, a set homeomorphic to the Cantor set, a set homeomorphic to the set T of subsums of Σn=1∞
x(n) where c(2n − 1) = 3/4n and c(2n) = 2/4n (Cantorval). Based on ideas of Jones and Velleman [Jones R., Achievement sets of sequences, Amer. Math. Monthly, 2011, 118(6), 508–521] and Guthrie and Nymann [Guthrie J.A., Nymann J.E., The topological structure of the set of subsums of an infinite series, Colloq. Math., 1988, 55(2), 323–327] we describe families of sequences which contain, according to our knowledge, all known examples of x with E(x) being Cantorvals.
