Indirect method for validating transference of reference intervals
Authors: Lykkeboe Simon , Nielsen Claus Gyrup , Christensen Peter Astrup 
Published: October 2017

Abstract

Background:
Transference of reference intervals (RIs) from multicentre studies are often verified by use of a small number of samples from reference individuals or by the use of one serum sample (Serum X for NORIP RI). Despite recommended and appropriate methods, both have inconveniencies and drawbacks. Several attempts have been made to develop an indirect method, which uses historical data from the laboratory. These methods are retrospective relying on older test results. A near prospective method would be preferable for the laboratories introducing new methods or changing analytical platforms.

Methods:
We performed a data mining experiment using results from our laboratory information system covering patients from a large geographic area. Request patterns for patients with assumed healthy characteristics were identified and used to extract laboratory results for calculation of new RI by an indirect method. Calculated RI and confidence intervals (CIs) were compared to transferred NORIP RI verified by NFKK Reference Serum X.

Results:
We found that our indirect method and NFKK Reference Serum X in general produced similar results when verifying transference of RI. The method produces results for all stratifications. Only single stratifications and one analyte showed unexplained incongruences to the NORIP RI.

Conclusions:
Our results suggest using request patterns as a surrogate measure for good health status. This allows for a data mining method for validation of RI or validating their transference, which is likely to be applicable in countries with similar healthcare and laboratory information system.

Authors: Khoomwong Ekajit , Phongcharoenpanich Chuwong 
Published: October 2017

AbstractIn this research, a dual-band thin printed-circuit-board (PCB) microwave absorber has been proposed for applications in 2.4 and 5 GHz frequency bands. Each unit cell of the absorber consists of a square ring and a thick cross-dipole, augmented with the tuning elements. In the design process, numerical simulations were performed for the optimal characteristics of the absorber and an absorber prototype was fabricated using the simple print-transferring and etching process. The measured absorption bandwidths (50 %) of 170 MHz (2.36–2.53 GHz) and 830 MHz (5.09–5.92 GHz) were achieved for the first and second bands, respectively, with the wideband characteristic at the second operating band. The absorption rates near the center frequencies (2.45 and 5.5 GHz) were respectively 97.85 % and 97.76 %. The simulation and measured results are in good agreement. Furthermore, the incidence-angle dependencies of the absorber were of moderately wide angles with the absorption capacity of at least 50 % for both operating bands. The proposed absorber is suitable for a variety of applications requiring absorption in the 2.4/5 GHz bands.

Authors: Elhag Mohamed 
Published: October 2017

AbstractUtilization of satellite data by means of remote sensing practices creates a wider window of opportunities to conduct robust outcomes Landsat OLI-8 data acquired over the peninsula of Halkidiki in Greece for the summer period of 2013, were analyzed to determine their utility to classify natural resources categories based on the determination of spectral bands combination. Consequently, spectral bands combination can be used to classify various categories based on their higher overall accuracy assessment. Spectral information contained in each of the utilized channels of Landsat OLI-8, statistics defining 12 cover type classes of interest were calculated and used as a basis for classification of the designated study area. Spectral bands combinations (4-5-6/ 3-4-5/ 3-4-5-6/ 4-5-6-7) fulfill the required accuracy for forest purpose as they conducted overall accuracies ranging between 7.85% and 96.29%. The spectral band combination 3-4-5-6-7 conducted the highest overall accuracy (98.15%). The poorest results were obtained by the analysis of spectral bands combination 4-6 (68.52%). Single spectral band 6 conducted the best overall results; however, spectral bands 5 and 6 seemed to be the most useful spectral bands combination for each category.

Published: October 2017

AbstractPlywood panels prepared from loblolly pine with cured phenol resin (PF) and urea-formaldehyde resin (UF) were submitted to accelerated aging and the microstructures and mechanics of wood-resin interphase were studied by nanoindentation (NI) and nanoscale dynamic mechanical analysis (Nano-DMA). The mass loss (ML) of wood, PF and UF resins were 3.4, 5.0 and 4.6% after aging treatment, respectively, and a large amount of microcracks were observed on the surface of wood and resins after aging treatment, which also affected the static mechanics of the cell walls far from the interphase region and the resins in the interphase region. The elastic modulus (Er) and hardness (H) values of the cell wall decreased by 7.2 and 9.5%, respectively, against the untreated control. The storage and loss modulus of the resins decreased significantly after aging treatment. The significant inconsistency in the mechanics, shrinkage and swelling properties of wood cell wall and resin in the interphase region after aging treatment resulted in a decrease of about 47 and 51% on the average bonding strength of the plywood made of PF and UF resins, respectively.
Effect of the Operating Conditions on the Growth of Carbonaceous Nanomaterials over Stainless Steel Foams. Kinetic and Characterization Studies
Authors: Latorre Nieves , Cazaña Fernando , Sebastián Víctor , Royo Carlos , Romeo Eva , Monzón Antonio 
Published: October 2017

Abstract
This work is an advance on the development of structured catalytic reactors. Here, we present the results of the effect of the main operational variables (reaction temperature, % H2 and % C2H6) on the kinetics of carbonaceous nanomaterials (CNMs) formation by catalytic decomposition of ethane over stainless steel foams. Some of the main drawback problems that occur during the operation of chemical structured reactors are related to the preparation of long term stable coatings. The washcoating is the most used technique to deposit the catalytic layer over the substrate. The application of this procedure is quite complex in the case of geometries such as foams or cloths. In the case of the deposition of layers of carbonaceous nanomaterials, an alternative route, avoiding the washcoating, is their direct growth by catalytic decomposition of light hydrocarbons over the surface of the metallic substrate. In the case of structured steel foams, the substrate already contains the catalytic active phases for this reaction, like Fe and Ni, among of the minor components (Cr, Mn, Mo) that can act as promotors/stabilizers.
The nanomaterials obtained after reaction were characterized by Raman spectroscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The characterization results indicate that there is a maximum, obtained at ca. 900 °C, 33.3 % of C2H6 and 1.7 % of H2, in the quality of the carbonaceous nanomaterials grown. Under these conditions, the CNMs consist mainly of few layer graphene (FLG) and graphite nanolayers (GNL) encapsulating the metallic nanoparticles. In addition, the kinetic results indicate the existence of another optimum, at ca. 800 °C, 33.3 % of C2H6 and 1.7 % of H2, in the productivity to the carbonaceous nanomaterials. The existence of these optimums is due to the driving force for the diffusion of the carbon atoms through the Fe-Ni nanoparticles (NPs) obtained at high temperatures (e. g. above 800 °C) caused by the competence between two opposite phenomena: the increase of the rate of carbon diffusion through the metallic nanoparticles of Fe-Ni and the deactivation of these nanoparticles. The deactivation is the consequence of the encapsulation and reconstruction of the nanoparticles during the formation of the several types of CNMs. The evolution of the carbon mass during the reaction time was analyzed using a phenomenological kinetic model that takes into account the main stages involved during the formation of carbonaceous nanomaterials: hydrocarbon decomposition, carburization, diffusion, precipitation and deactivation. The results obtained from the kinetic model, along with the characterization results, enable quantify the influence of the operating variables on each stage of the carbonaceous nanomaterial formation and therefore open the way to optimize the process.

Published: October 2017

Abstract
A simple method called low-temperature vacuum drying (LTVD) was used to produce a novel dehydrated potato flour called raw dehydrated potato flour (RDPF). Preparing RDPF by LTVD at 60°C, 70°C and 80°C in both slice and dice shape was investigated. Potato samples in dice shape are easier dehydrating than in slice shape, the starch granules of RDPF maintain ellipsoid shape as the native potato starch. The best temperature of LTVD to prepare the RDPF is around 70°C according to CIE chromaticity results. Dehydrate at 60°C in dice shape, 88.37% of the trypsin inhibitor activity of the fresh potato is maintained. The Mixolab curve shows that the RDPF has some similar rheological properties of the wheat flour. Protein undenatured, starch ungelatinized, with the high performance of processing properties, RDPF has a number of potential applications in the potato staple food manufacture.

Performance Evaluation of Modified Color Image Steganography Using Discrete Wavelet Transform
Authors: Kumar Vijay , Kumar Dinesh 
Published: October 2017

AbstractSteganography is the foremost influential approach to hide data. Images serve as the most appropriate cover media for steganography. This paper intends to do a performance evaluation of color images and its comparison with the recently proposed approaches, using the modified technique already proposed for grayscale images, by the authors. This approach hides large data in color image using the blocking concept. The blocking process is applied on approximation coefficients of secret image and detail coefficients of red, green and blue components of cover image. The blocks of detail coefficients are replaced with approximation coefficients of secret image using root mean square error method. The key is used to store the position of best matching blocks. It is being predicated that the work will be able to hide large data in a single image. The stego image (ST) has better visual quality based on the peak signal to noise ratio values.

Authors: van der Knoop Bloeme J. , Vermeulen Roland J. , Verbeke Jonathan I.M.L. , Pistorius Lourens R. , de Vries Johanna I.P. 
Published: October 2017

Abstract

Aim:
To determine acceptance of pregnant women to undergo fetal magnetic resonance imaging (MRI) examination in research and clinical setting.

Methods:
A prospective study included a research group [part of a study comparing brain ultrasound (US) to MRI in fetuses at risk for acquired brain damage] and a clinical group [fetuses with suspected (brain) anomalies after structural US examination] from 2011 to 2014. All women were advised to use sedatives. MRI declinations, use of sedation, MRI duration and imaging quality were compared between both groups.

Results:
Study participation was accepted in 57/104 (55%) research cases. Fetal MRI was performed in 34/104 (33%) research and 43/44 (98%) clinical cases. Reasons to decline study participation were MRI related in 41%, and participation was too burdensome in 46%. Acceptance was highest for indication infection and lowest in alloimmune thrombocytopenia and monochorionic twin pregnancy. Sedatives were used in 14/34 research and 43/43 clinical cases. Scan duration and quality were comparable (21 and 20 min in research and clinical cases, respectively, moderate/good quality in both groups).

Conclusions:
Pregnant women consider MRI more burdensome than professionals realize. Two-third of women at risk for fetal brain damage decline MRI examination. Future studies should evaluate which information about fetal MRI is supportive.
Experimental and theoretical investigations of the high performance blends of PEEK/PEI
Authors: Kumar Sandeep , Mishra Raghvendra K. , Nandi Tandra 
Published: October 2017

Abstract
Polyether ether ketone (PEEK) and polyether imide (PEI) blends were made by melt blending using a twin-screw extruder. The blends were characterized by mechanical testing, thermal, rheological and morphological studies. Predictive models were used to explain the tensile modulus and strength properties. The impact strength increases when percentage of the PEI increases in composite. This has been analyzed on the basis of the interphase adhesion. Tensile and flexural strength also increased with increase in the PEI content. Incorporation of PEI increases the glass transition temperature (T

g
) and facilitates its processing. Scanning electron microscopy (SEM) was employed to study the phase structure. These experimental findings are in agreement with predictive models based on the rule of mixture and the Nicolais-Narkis model. Multi quadric radial basis function (MQRBF) was applied to study the static and dynamic response of the PEEK/PEI blend plate at uniformly distributed load. The present results were compared with numerical and analytical results.
Investigating the properties of maleated poly(lactic acid) and its effect on poly(lactic acid)/cellulose nanofiber composites
Authors: Ghasemi Somayeh , Behrooz Rabi , Ghasemi Ismail 
Published: October 2017

Abstract
In this research, maleated poly(lactic acid) (PLA-g-MA) was manufactured by different levels of maleic anhydride (MAH). Also PLA-g-MA effects as a compatibilizer were investigated on PLA/cellulose nanofiber (CNF) composites. The grafting reaction was performed in the presence of dicumyl peroxide (DCP) as an initiator at constant level (0.2 phr) via reactive extrusion. Furthermore, the effects of four different levels of MAH (1–4 phr) were studied on the physical properties of PLA grafted films. We used the Fourier transform infrared (FTIR) and titration methods for confirmation of the grafting process. Based on the titration method, the greatest amount of yield was gained by 4 phr of MAH in grafting. Contact angle analysis shows that increasing the amount of MAH led to a decrease in the contact angle of films. Moreover, the glass transition temperature (Tg) and % crystallinity were decreased by increasing MAH content. PLA-g-MA was added to the composites in two levels of 3% and 5% in total. CNF was used at a constant level of 5%. The thermal, morphological and mechanical properties of nanocomposites were determined as a function of PLA-g-MA content using thermogravimetric analysis, heat distortion temperature (HDT) and tensile testing. All the prepared nanocomposite materials showed improvement in the mechanical and thermal properties compared to neat PLA.

Published: October 2017

Abstract
In the present study, dielectric and thermal properties of poly(aryl ether ketone) (PAEK)-nanocomposites with varying weight percentage of magnesium oxide (MgO) have been reported. The thermal properties of PAEK/MgO nanocomposites were studied using differential scanning calorimetry, thermogravimetric analysis, thermo-mechanical analysis and thermal conductivity. Transmission electron microscopy of the developed nanocomposites shows agglomerate-free dispersion of MgO nanoparticles in PAEK matrix. From the dielectric properties, dielectric constant of 13 was achieved for 10 wt% PAEK/MgO nanocomposite at 230°C. Further, minimum tan δ and maximum volume resistivity were found for 10 wt% PAEK/MgO nanocomposite. Data from thermal studies indicate that the incorporation of MgO into PAEK significantly enhanced the glass transition temperature and slightly deteriorated the thermal stability, char yield, and flame-retardant properties. Also, highest thermal conductivity and lowest coefficient of thermal expansion were achieved at 10 wt% of the MgO content. An excellent combination of both dielectric and thermal properties of the PAEK/MgO nanocomposites developed in the present study finds its potential application in microelectronics and electrical insulation in power equipments.
