Morphology of polyamide 6 confined into carbon nanotubes
Authors: Piegat Agnieszka , Staniszewski Zygmunt , Poeppel Artur , El Fray Miroslawa 
Published: July 2015

Abstract
The preparation of polymer nanocomposites filled with carbon nanotubes requires the nanotubes to be uniformly dispersed and compatible with the polymer matrix. In this work we report a preparation method of polyamide 6 (PA 6) based nanocomposite containing multi-walled carbon nanotubes (MWCNT) without any additional surface modification and obtained by in situ polymerization, as a simple method for composites production. The process was assisted by ultrasounds prior to synthesis.With such a method, an interesting morphology of polyamide 6 confined into a multiwalled carbon nanotube as well as grafted on a carbon nanotube surface was observed. For comparative purpose, PA 6 nanocomposites were also prepared from commercially available master batch by melt compounding.
Solvothermal synthesis and magnetic properties of β-Co2P nanorods
Authors: Li Tian , Liao Jun Peng , Wang Ying Feng 
Published: July 2015

Abstract
Hexagonal high temperature phase β-Co2P nanorods with a diameter of around 50 nm were synthesized via a mild solvothermal route. The reaction was carried out at 180 °C using cobalt chloride hexahydrate (CoCl2 · 6H2O) as Co source and yellow phosphorous as P source. The composition, structure as well as morphology were characterized by X-ray diffraction (XRD), X-ray photoemission spectroscopy (XPS) and transmission electron microscopy (TEM). The magnetic susceptibility curve indicates that the β-Co2P nanorods show canted antiferromagnetic state, different from the paramagnetic state of orthorhombic low temperature phase β-Co2P.

Web Presence of Indian Digital Culture
Authors: Sharma Seemu , Bawa Seema , Lomash Hitashi 
Published: July 2015

AbstractOur day-to-day needs are greatly dependent on information and communications technology (ICT)—as represented by the Internet. Knowledge about culture is no exception. This paper focuses on the availability of digital cultural information about India on the Web. We aim to answer three questions: How is Indian culture represented on the Web? How are Indian cultural heritage sites being used? Who is using the sites? The study also examines the usability of these sites, and whether they are maintained. Content, ranking, and users’ age groups are the three criteria on which this analysis has been based.
Using Theory to Understand Digital Preservation Management in Ghana
Authors: Boamah Eric , Dorner Daniel George , Oliver Gillian 
Published: July 2015

AbstractIn this paper we discuss how Rogers’ Diffusion of Innovation theory and Davies’ Policy, Strategy and Resources (PSR) troika model were used to underpin a Ph. D. study that explored contextual factors influencing the current state of digital preservation management in Ghana. Our goal is to explain how these theories were employed so that other researchers will be able to use them effectively to understand other related research problems. The research on which this paper is based employed an interpretive single-case-study approach. Four main clusters of contextual factors—attitude-related, resource-related, policy-related, and management-related factors—were found to be influencing digital preservation management in Ghana. We present a summary of these factors at the end of the paper. Awareness of these can enable the effective development of a digital preservation program and lead to the establishment of a national digital memory for Ghana and other developing countries.
The Polish Adaptation of FACES IV-SOR
Authors: Margasiński Andrzej 
Published: July 2015

Abstract
My paper describes a Polish adaptation of the family assessment tool called FACES IV. Confirmatory factor analysis showed a good fit of the model to the data with a sample of 499 Polish individuals from 150 families. The reliability measures of the two Balanced scales are similar to those of the American scales. However, the four Unbalanced scales have lower reliability. Reliability measures of Family Satisfaction and Family Communication are even higher than the American ones. A cluster analysis clearly depicted the extreme profiles of the Balanced and Unbalanced scales, with the remaining four profiles also present. Norms were developed for the various scales. Psychometric verification of this instrument showed that FACES IV-SOR is useful for research and clinical work with Polish families.
What Drives Shopping Mall Attractiveness?
Authors: Dębek Michał 
Published: July 2015

Abstract
My article investigated the drivers of shopping mall attractiveness. Which of various shopping mall qualities are key to building a mall’s attractiveness? This was the fundamental question in the cross-sectional, survey-based correlational study. The participants included 384 adult Poles (192 men and 192 women whose median age was 22). The survey included 58 items – nine to measure the shopping mall’s attractiveness (its emotional impact, cognitive effect and the customer’s visiting frequency), and 49 to measure its hypothetical predictors. The investigated objects were six urban shopping malls in Wroclaw, Poland. It turned out that shopping mall attractiveness was driven mainly by their atmosphere and social positioning. Surprisingly, the more subjectively noisy and crowded the shopping mall was, the more attractive it appeared to be; commerce-related features, on the other hand, while usually treated as vital to a shopping center, contributed relatively little to the mall’s attractiveness.

Published: July 2015

Abstract
The species composition and number of visitations of food plants by bees were studied in refuge sites in agricultural landscapes and in selected crops. The habitat fragments of interest are characterised in terms of pollinator diversity at genus level and the use of food plants by individual genera. Trophic and temporal niche overlap is described for individual genera and the honey bee Apis mellifera in different habitat types. Factors influencing the manner of use of individual plant species by pollinating insects are identified
Fibulin-3 as a biomarker of response to treatment in malignant mesothelioma
Authors: Kovac Viljem , Dodic-Fikfak Metoda , Arneric Niko , Dolzan Vita , Franko Alenka 
Published: July 2015

Abstract

Background. Fibulin-3 is a new potential biomarker for malignant mesothelioma (MM). This study evaluated the potential applicability of fibulin-3 plasma levels as a biomarker of response to treatment and its prognostic value for progressive disease within 18 months. The potential applicability of fibulin-3 in comparison with or in addition to soluble mesothelin-related peptides (SMRP) was also assessed.

Patients and methods. The study included 78 MM patients treated at the Institute of Oncology Ljubljana between 2007 and 2011. Fibulin-3 levels in plasma samples obtained before treatment and in various responses to treatment were measured with the enzyme-linked immunosorbent assay.

Results. In patients evaluated before the treatment, fibulin-3 levels were not influenced by histopathological sub-types, tumour stages or the presence of metastatic disease. Significantly higher fibulin-3 levels were found in progressive disease as compared to the levels before treatment (Mann-Whitney [U] test = 472.50, p = 0.003), in complete response to treatment (U = 42.00, p = 0.010), and in stable disease (U = 542.00, p = 0.001). Patients with fibulin-3 levels exceeding 34.25 ng/ml before treatment had more than four times higher probability for developing progressive disease within 18 months (odds ratio [OR] = 4.35, 95% confidence interval [CI] 1.56–12.13). Additionally, patients with fibulin-3 levels above 34.25 ng/ml after treatment with complete response or stable disease had increased odds for progressive disease within 18 months (OR = 6.94, 95% CI 0.99–48.55 and OR = 4.39, 95% CI 1.63–11.81, respectively).

Conclusions. Our findings suggest that in addition to SMRP fibulin-3 could also be helpful in detecting the progression of MM.
Endobronchial ultrasound elastography strain ratio for mediastinal lymph node diagnosis
Authors: Rozman Ales , Marc Malovrh Mateja , Adamic Katja , Subic Tjasa , Kovac Viljem , Flezar Matjaz 
Published: July 2015

Abstract

Background. Ultrasound elastography is an imaging procedure that can assess the biomechanical characteristics of different tissues. The aim of this study was to define the diagnostic value of the endobronchial ultrasound (EBUS) elastography strain ratio of mediastinal lymph nodes in patients with a suspicion of lung cancer. The diagnostic values of the strain ratios were compared with the EBUS brightness mode (B-mode) features of selected mediastinal lymph nodes and with their cytological diagnoses.

Patients and methods. This prospective, single-centre study enrolled patients with an indication for biopsy and mediastinal staging after a non-invasive diagnostic workup of a lung tumour. EBUS with standard B-mode evaluation and elastography with strain ratio measurement were performed before endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).

Results. Thirty-three patients with 80 suspicious mediastinal lymph nodes were included. Malignant infiltration was confirmed in 34 (42.5%) lymph nodes. The area under the receiver operating characteristic curve for the strain ratio was 0.87 (p < 0.0001). At a strain ratio ≥ 8, the accuracy for malignancy prediction was 86.25% (sensitivity 88.24%, specificity 84.78%, positive predictive value [PPV] 81.08%, negative predictive value [NPV] 90.70%). The strain ratio is more accurate than conventional B-mode EBUS modalities for differentiating between malignant and benign lymph nodes.

Conclusions. EBUS-guided elastography with strain ratio assessment can distinguish malignant from benign mediastinal lymph nodes with greater accuracy than conventional EBUS modalities. This new method may reduce the number of mediastinal EBUS-TBNAs and thus reduce the invasiveness and expense of mediastinal staging in patients with non-small lung cancer (NSCLC).
Central nervous system imaging in childhood Langerhans cell histiocytosis – a reference center analysis
Authors: Porto Luciana , Schöning Stefan , Hattingen Elke , Sörensen Jan , Jurcoane Alina , Lehrnbecher Thomas 
Published: July 2015

Abstract

Background. The aim of our study was (1) to describe central nervous system (CNS) manifestations in children with Langerhans cell histiocytosis (LCH) based on images sent to a reference center and meeting minimum requirements and (2) to assess the inter-rater agreement of CNS-MRI results, which represents the overall reproducibility of this investigation.

Methods. We retrospectively reviewed brain MRI examinations in children with LCH, for which MRI minimum requirements were met. Abnormalities were rated by two experienced neuroradiologists, and the inter-rater agreement was assessed.

Results. Out of a total of 94 imaging studies, only 31 MRIs met the minimum criteria, which included T2w, FLAIR, T1w images before/after contrast in at least two different section planes, and thin post contrast sagittal slices T1w through the sella. The most common changes were osseous abnormalities, followed by solid enlargement of the pineal gland, thickened enhancing stalk and signal changes of the dentate nucleus. Whereas inter-rater agreement in assessing most of the CNS lesions was relatively high (κ > 0.61), the application of minimum criteria often did not allow to evaluate the posterior pituitary.

Conclusions. The diversity of radiological protocols from different institutions leads to difficulties in the diagnosis of CNS abnormalities in children with LCH. Although the inter-rater agreement between neuroradiologists was high, not all the LCH manifestations could be completely ruled out when using the minimum criteria. Brain MRIs should therefore follow LCH guideline protocols and include T1 pre-gadolinium sagittal images, and be centrally reviewed in order to improve the comparison of clinical trials.
CA19-9 serum levels predict micrometastases in patients with gastric cancer
Authors: Jagric Tomaz , Potrc Stojan , Mis Katarina , Plankl Mojca , Mars Tomaz 
Published: July 2015

AbstractBackgroundWe explored the prognostic value of the up-regulated carbohydrate antigen (CA19-9) in node-negative patients with gastric cancer as a surrogate marker for micrometastases.Patients and methodsMicrometastases were determined using reverse transcription quantitative polymerase chain reaction (RT-qPCR) for a subgroup of 30 node-negative patients. This group was used to determine the cut-off for preoperative CA19-9 serum levels as a surrogate marker for micrometastases. Then 187 node-negative T1 to T4 patients were selected to validate the predictive value of this CA19-9 threshold.ResultsPatients with micrometastases had significantly higher preoperative CA19-9 serum levels compared to patients without micrometastases (p= 0.046). CA19-9 serum levels were significantly correlated with tumour site, tumour diameter, and perineural invasion. Although not reaching significance, subgroup analysis showed better five-year survival rates for patients with CA19-9 serum levels below the threshold, compared to patients with CA19-9 serum levels above the cut-off. The cumulative survival for T2 to T4 node-negative patients was significantly better with CA19-9 serum levels below the cut-off (p= 0.04).ConclusionsPreoperative CA19-9 serum levels can be used to predict higher risk for haematogenous spread and micrometastases in node-negative patients. However, CA19-9 serum levels lack the necessary sensitivity and specificity to reliably predict micrometastases.

Published: July 2015

Abstract
Molluscan diversity in selected Protected Landscape Areas (PLA) of Bohemia (Czech Republic) was monitored. For the study, the small-scale PLAs of the Slavkovský Les, the Blanský Les, and the Labské Pískovce were selected. Over 12 500 specimens in total representing 62 mollusc species were found within 2012-2013 by means of hand collecting and sieving the litter layer. To evaluate similarity among the localities, the Jaccard and Sörensen’s indices were calculated. The significance of such data is mainly in their presentation in the available resources such as peer-reviewed scientific journals
Raffinose-Series Oligosaccharides in Soybean Products
Authors: Švejstil R. , Musilová Š. , Rada V. 
Published: July 2015

Abstract
Soybean foods forming a substantial part of Asian diet have still more expanded into European diet. Raffinose-series oligosaccharides (RSO) are important constituents of soya beans and they can be found also in soybean products. These oligosaccharides can be considered potentially prebiotic for their capability of influencing the composition of the host’s intestinal microbiota. The aim of the present paper was to determine the oligosaccharide content in various soybean products. Enzymatic assay has been used for the determination of oligosaccharides. RSO have been found in all tested samples and their content varied from 0.66 g per 100 g in soybean beverage to 5.59 g per 100 g in first clear soybean flour. Generally, the highest content of RSO has been detected in soybean flour in the average amount of 4.83 g per 100 g. There was no statistically significant difference observed in the amount of oligosaccharides in all four types of soybean flour (P < 0.01). Considerably high amounts of RSO have been found in sweet soybean bars and textured soy protein. Foods as soybean flour and soybean bar ‘Sójový suk’ seem to be effective natural sources of prebiotic oligosaccharides for humans.
Numerical and experimental determination of in-structure temperature profiles
Authors: Zozulák Marek , Katunský Dušan 
Published: July 2015

Abstract
When building physics simulations are done initial conditions express the actual hygrothermal state of building envelope. For the temperature field simulations initial condition is represented by the initial temperature in the body profile at the start of heat transfer. In-structure temperature varies quickly so temperature initial conditions are often neglected. Nevertheless in specific cases initial conditions have to be taken into an account even when simple temperature field simulations are done. The contribution shows various temperature initial conditions determination for insulated construction of outdoor test cell. Comparison of measured and calculated temperature profiles in structure shows correctness of start-up pre-calculation initial condition consideration

Published: July 2015

Abstract
This paper presents the results obtained from the research focused on the utilization of crushed concrete waste aggregates as a partial or full replacement of 4/8 and 8/16 mm natural aggregates fraction in concrete strength class C 16/20. Main concrete characteristics such as workability, density and compressive strength were studied. Compressive strength testing intervals for samples with recycled concrete aggregates were 2, 7, 14 and 28 days. The amount of water in the mixtures was indicative. For mixture resulting consistency required slump grade S3 was followed. Average density of all samples is in the range of 2250 kg/m3 to 2350 kg/m3. The highest compressive strength after 28 days of curing, 34.68 MPa, reached sample, which contained 100% of recycled material in 4/8 mm fraction and 60% of recycled aggregates in 8/16 mm fraction. This achieved value was only slightly different from the compressive strength 34.41 MPa of the reference sample.

OBJECTIVE:To examine demographics and trends of financial cost and prominent diseases/conditions resulting in inpatient hospitalizations for infants, children, and adolescents in Texas between 2004 and 2010.METHODS:Longitudinal retrospective cross-sectional study using the Texas Hospital Inpatient Discharge Database, including all pediatric hospitalizations in the state of Texas, 2004 to 2010.RESULTS:Texas has an average of 591 571 pediatric hospitalizations per year. Birth was the most common reason for hospitalization, representing 64% of all pediatric hospitalization annually in Texas. Respiratory illnesses were the most common discharge diagnosis for hospitalized children ages 1 month to 9 years and demonstrated a 2% decrease over the study period. The rate of hospitalizations for digestive conditions and childbirth also demonstrated a decrease over this time frame: 4.7% and 3.0%, respectively. The rate of mental illness diagnoses increased 2.5% over the time frame and represented the most common discharge diagnosis for children aged 10 to 14. Childbirth was the most common reason for hospitalization for adolescents aged 15 to 17 years. There was no increase in total cost of pediatric hospitalizations over the time period under study.CONCLUSIONS:After birth, respiratory illnesses represent the most common reason for hospitalization for children (between 1 month and 10 years of age) in Texas. Mental health conditions and childbirth represent the most common reason for hospitalization for young adolescents (10–14 years) and older adolescents (15–17 years), respectively.
