Published: September 2016

Objectives The spinopelvic relationship (including pelvic incidence) has been shown to influence pelvic orientation, but its potential association with femoroacetabular impingement has not been thoroughly explored. The purpose of this study was to prove the hypothesis that decreasing pelvic incidence is associated with increased risk of cam morphology. Methods Two matching cohorts were created from a collection of cadaveric specimens with known pelvic incidences: 50 subjects with the highest pelvic incidence (all subjects > 60°) and 50 subjects with the lowest pelvic incidence (all subjects < 35°). Femoral version, acetabular version, and alpha angles were directly measured from each specimen bilaterally. Cam morphology was defined as alpha angle > 55°. Differences between the two cohorts were analysed with a Student’s t-test and the difference in incidence of cam morphology was assessed using a chi-squared test. The significance level for all tests was set at p < 0.05. Results Cam morphology was identified in 47/100 (47%) femurs in the cohort with pelvic incidence < 35° and in only 25/100 (25%) femurs in the cohort with pelvic incidence > 60° (p = 0.002). The mean alpha angle was also greater in the cohort with pelvic incidence < 35° (mean 53.7°, sd 10.7° versus mean 49.7°, sd 10.6°; p = 0.008). Conclusions Decreased pelvic incidence is associated with development of cam morphology. We propose a novel theory wherein subjects with decreased pelvic incidence compensate during gait (to maintain optimal sagittal balance) through anterior pelvic tilt, creating artificial anterior acetabular overcoverage and recurrent impingement that increases risk for cam morphology.

A concrete realization of the slow-fast alternative for a semilinear heat equation with homogeneous Neumann boundary conditions
Authors: Ghisi Marina , Gobbino Massimo , Haraux Alain 
Published: September 2016

Abstract
We investigate the asymptotic behavior of solutions to a
semilinear heat equation with homogeneous Neumann boundary
conditions.
It was recently shown that the nontrivial kernel of the linear
part leads to the coexistence of fast solutions decaying to 0
exponentially (as time goes to infinity), and slow solutions
decaying to 0 as negative powers of t.
Here we provide a characterization of slow/fast solutions in terms
of their sign, and we show that the set of initial data giving
rise to fast solutions is a graph of codimension one in the phase
space.

Authors: Matijošaitienė Irina , Gedvilaite Monika 
Published: September 2016

Abstract
Crime is a social phenomenon, which is closely related to human behaviour, economics, urban planning and design. The detailed research of six blocks of houses in three Lithuanian cities (Kaunas, Vilnius and Panevezys) with the highest crime rates and the most heterogeneous crimes was performed. Space syntax method, crime prevention through environmental design (CPTED) and correlation analysis were applied. Research results demonstrate that thefts from cars, other thefts, crime against human health, robberies, small-scale hooliganism and intentional damage or destruction of property correlate with particular properties of urban spaces and design elements.

Tracing ethnic socialisation of Chinese in Malaysia to Chinese-medium school
Authors: Phooi-Yan Lee Diana , Ting Su-Hie 
Published: September 2016

Abstract
The study examined the ethnic socialisation by comparing the influences of the family and school on the development of ethnic identity. The participants were 397 Malaysians of Chinese descent with Malay, Chinese and English educational backgrounds. Familial ethnic socialisation was moderate and similar for the three groups. They were similar in the resolution and affirmation dimensions of their ethnic identity. The role of Chinese-medium school in ethnic socialisation is evident in the greater exploration of ethnicity by the Chinese-educated participants. This group also valued Chinese-medium education and the Chinese language, Chinese name and Chinese festivals as markers of Chinese identity. However, the other two groups did not believe in marking their Chinese identity. Considering that ethnicised identity is a given in Malaysia, the findings suggest that the Chinese who did not have Chinese educational background may be migrating from Chinese ethnicity to notion of the Malaysian race (Bangsa Malaysia).

Published: September 2016

Abstract
Pokemon is a transcriptional repressor that belongs to the POZ and Krüppel (POK) protein family. In this study, we investigated the potential interaction between Pokemon and retinoic acid receptor alpha (RARα) and determined the role of Pokemon in regulation of RARα transcriptional activity in the absence of ligand. We found that Pokemon could directly interact with RARα. Moreover, we demonstrated that Pokemon could decrease the transcriptional activity of RARα in the absence of ligand. Furthermore, we showed that Pokemon could repress the transcriptional activity of RARα by increasing the recruitment of nuclear receptor co-repressor (NCoR) and silencing mediator of retinoic acid and thyroid hormone receptor (SMRT) to the retinoic acid response element (RARE) element. Taken together, these data suggest that Pokemon is a novel partner of RARα that acts as a co-repressor to regulate RARα transcriptional activity in the absence of ligand.

Published: September 2016

Abstract
This paper proposes a hybrid method for calculating lightning performance of overhead lines caused by direct strokes by combining Lattice diagram together with the Monte Carlo method. In order to go through this, firstly, the proper analytical relations for overvoltages calculation are established based on Lattice diagram. Then, the Monte Carlo procedure is applied to the obtained analytical relations. The aim of the presented method that will be called ‘ML method’ is simply estimation of the lightning performance of the overhead lines and performing the risk analysis of power apparatus with retaining the acceptable accuracy. To confirm the accuracy, the calculated results of the presented ML method are compared with those calculated by the EMTP/ATP simulation.
Adaptive Testing for Nondestructive Evaluation of Degraded Materials
Authors: Tomáš Ivan , Vértesy Gábor 
Published: September 2016

Abstract
Method of Adaptive testing (AT) is described, as a way of optimization of experimental evaluation of degraded materials, which are measured nondestructively, indirectly via a convenient physical process. The general AT is illustrated by a well-explored special case of magnetic adaptive testing (MAT) of strained steel. Degradation curves obtained from AT are regularly more sensitive and experimentally friendly than traditional descriptors of the used physical process itself. Any of the traditional descriptors of the physical process, being optimized for description of the process itself, is very probably not optimized for description of the investigated material degradation.

Published: September 2016

Abstract
Wireless indoor localization has generated recent research interest due to its numerous applications. This work investigates Wi-Fi based indoor localization using two variants of the fingerprinting approach. Specifically, we study the application of an artificial neural network (ANN) for implementing the fingerprinting approach and compare its localization performance with a probabilistic fingerprinting method that is based on maximum likelihood estimation (MLE) of the user location. We incorporate spatial correlation of fading into our investigations, which is often neglected in simulation studies and leads to erroneous location estimates. The localization performance is quantified in terms of accuracy, precision, robustness, and complexity. Multiple methods for handling the case of missing APs in online stage are investigated. Our results indicate that ANN-based fingerprinting outperforms the probabilistic approach for all performance metrics considered in this work.

Published: September 2016

Abstract
The 57Fe Mössbauer spectroscopy method was used to investigate iron-containing compounds in town Košice meteorite fallen on the territory of Slovakia in February 2010. The results showed that the Mössbauer spectra consisted of magnetic and non-magnetic components related to different iron-bearing phases. The non-magnetic phase includes olivine, pyroxene and traces of Fe3+ phase and the magnetic component comprises troilite (FeS) and iron-rich Fe-Ni alloy with hyperfine magnetic field typical for kamacite. Samples from meteorite were obtained in powder from different depths to inspect its heterogeneous composition. The content of kamacite increases to the detriment of troilite from the surface toward the centre of the sample. Measurements at liquid nitrogen temperature confirmed phase composition of investigated meteorite. Main constituent elements of studied samples were also determined by X-ray fluorescence analysis.

Published: September 2016

AbstractIn this research work, a statistical model is developed for predicting the optimal process parameters of Fused Deposition Modelling (FDM) process for layout optimization. Multi response optimization of process parameters was achieved using Response Surface Methodology technique integrated with Genetic Algorithm. Response Surface Methodology (RSM) was utilized to design and conduct experiments. 86 experiments were conducted according to central composite design considering six process parameters namely raster width, raster angle, contour width, air gap, slice height and orientation to achieve four responses namely build time, model material volume, support structure volume and production cost. RSM-genetic algorithms (GA) integrated optimization is introduced in which GA is constructed including the development of coding strategy, evaluation operator and the fitness function. The constructed GA can meet the requirement of optimization work. The fitness function is defined as the sum of compulsive constraints or responses. All the constraints/responses have assigned same weightage. A Matlab genetic algorithm solver is utilized to predict best fitness values along with the optimal individual parameters in the present work.

Summary
Background: Serum small dense LDL-cholesterol (sdLDL-C) value is suggested to be an important risk factor for atherosclerosis. Since sdLDL-C changes may be related to PCSK9 and SREBP-2 functions, the aim of this study was to investigate correlations between sdLDL-C, circulating PCSK9, SREBP-2 expression and some lipid parameters in serum and buffy coat fraction of healthy subjects.
Methods: One hundred and twenty-four subjects were randomly included in the study. The lipid profile was measured using routine laboratory methods. The serum sdLDL-C level was calculated by a heparin-related precipitation technique. The cellular LDL-C/protein and cholesterol/protein values were measured after lysing of cells with methanol/chloroform binary solvent. The circulating PCSK9 level was measured using ELISA technique. The SREBP-2 expression level was estimated using the RT-qPCR technique.
Results: Data showed significant correlations between LDL-C, TG and sdLDL-C levels (r=0.34, p=0.001; r=0.2, p=0.04). The circulating PCSK9 level was correlated to LDL-C (r=0.29, p=0.04), but not to sdLDL-C (r=−0.08, p=0.57). Also, cellular LDL-C value was not related to serum LDL-C level (r=−0.12, p=0.39). Furthermore, there was an inverse correlation between cellular LDL-C/protein value and estimated de novo cholesterol/protein value (r=−0.5, p=0.001). Similar results were observed for cellular LDL-C/protein value and SREBP-2 expression level (r=−0.52, p=0.004).
Conclusions: We concluded that the serum sdLDL-C value is not related to circulating PCSK9. Furthermore, SREBP-2 regulatory system was able to elevate the cellular cholesterol level after reducing LDL influx. We suggest to investigate the cellular sdLDL fate and lipid synthesis pathways in PCSK9-targeting studies.
High Molecular Weight Adiponectin Levels are Neither Influenced by Adiponectin Polymorphisms Nor Associated with Insulin Resistance in Mixed-Ancestry Hyperglycemic Subjects from South Africa

Published: September 2016

SummaryBackground:High molecular weight (HMW) adiponectin has antiatherogenic, antiinflammatory and antidiabetic properties and these effects have been linked to its effect on high density lipoprotein cholesterol (HDL-c). Single nucleotide polymorphisms (SNPs) in the adiponectin gene influence adiponectin levels. We examined the relationship between HMW-adiponectin levels and cardiometabolic traits in normo- and hyperglycemic mixed ancestry South Africans and correlated these levels to two common polymorphisms.Methods:HMW-adiponectin was determined in 101 subjects from the Cape Town Bellville South community-based study on a mixed ancestry population. Comparisons were made between individuals with normo- and hyperglycemia. Two common SNPs,ADIPOQSNPs rs17300539 and rs266729, known to affect adiponectin levels were also tested for. Levels of HMW-adiponectin were then correlated with cardiometabolic traits in all groups.Results:Levels of HMW-adiponectin were not significantly different in the normo- and hyperglycemic groups (median 11.6 vs. 10.5 μg/mL, p=0.3060) and in men and women (8.44 vs. 11.34 μg/mL, p=0.67).ADIPOQSNPs rs17300539 and rs266729 did not influence levels of HMW-adiponectin. Robust correlation analyses revealed a significant positive correlation between HMW-adiponectin and HDL-c (r=0.45; 95%CI: 0.27–0.59), similarly in normo- and hyperglycemic participants (p>0.99). This association was substantially attenuated in robust linear regressions adjusted for age, gender and adiposity.Conclusions:Adiponectin levels in this population were not determined by the commonest SNPs of the adiponectin gene, were unaffected by glycemic status; but were significantly correlated with HDL-c levels. Previous studies have attributed some of the beneficial effects of adiponectin to its effect on HDL-c.
The effect of intraumbilical fetal nutrition via a subcutaneously implanted port system on amino acid concentration by severe IUGR human fetuses

Published: September 2016

AbstractObjective:To determine if intrauterine intraumbilical supplementation with amino acids (AA) and glucose can improve neonatal outcome of severe growth restricted human fetuses (IUGR).Methods:Prospective pilot study of intrauterine treatment of severe IUGR fetuses [n=14, 27 weeks of gestation (range 23–31)] with cerebroplacental ratio <1, with long-term intraumbilical AA and glucose supplementation (10% of feto-placental blood volume/day) using a perinatal port system alone (n=5) or combined with hyperbaric oxygenation (n=1, HBO) vs. control group (n=8).Results:The duration of continuous intraumbilical AA/glucose supplementation was 11 (6–13) days. Daily intravascular fetal nutrition significantly prolonged the brain sparing to delivery interval by 24 (14–33) days vs. 5.6 (2–12) days in controls. Fetal nutrition reduced blood flow resistance in the placental circulation but did not affect the Doppler profile of cerebral arteries. Higher weight gain of 113.5 (36–539) g was observed following supplementation compared to 33.3 (8–98) g in the control group (P<0.05). In spite of this, fetuses below 28 weeks of gestation did not sufficiently benefit from infused commercial AA. We found a reduced fetal plasma concentration of the essential AA histidine, threonine, lysine and arginine, and non-essential AA taurine, in severe IUGR fetuses in both groups. Long-term supplementation with a commercial AA formula led to a slight, but not significant, reduction of histidine, threonine, lysine, arginine, asparagine and glutamine. However, the concentration of tryptophan and glutamic acid slightly increased. HBO can be combined with AA supplementation via a port system. In one case, the port system was also successfully used for fetal blood transfusion.Conclusions:Intravascular treatment of IUGR with fetal nutrition can prolong pregnancy with severe placental insufficiency and brain sparing for many weeks. However, rather than normalizing AA concentrations, an enhanced AA imbalance was observed in IUGR fetuses following supplementation. These deviations in AA concentrations prevent the recommendation for use of commercial AA solutions for prenatal treatment of extreme preterm IUGR fetuses.

Published: September 2016

Abstract
The study is focused on evaluating hydrogen charging of materials in plating baths approved for aviation and in weak acid plating baths. For the evaluation, ASTM F519, ASTM F326 and a newly patented method of measuring device PCN1 - Pulsator cyclic loading were used. ASTM F519 is time consuming and the results are difficult to compare. ASTM F326 proved to be unsuitable for testing above plating baths because of strong hydrogen embrittlement of probes and thus their destruction. Conversely, the PCN1 method was fast and reproducible. Results showed that the baths approved for aviation caused stronger hydrogen embrittlement than weakly acidic zinc baths.

A Sensitivity Analysis on the Influence of the External Constraints on the Dynamic Behaviour of a Low Pollutant Emissions Aircraft Combustor-Rig
Authors: Amoroso Francesco , De Fenza Angelo , Petrone Giuseppe , Pecora Rosario 
Published: September 2016

Abstract
The need to reduce pollutant emissions leads the engineers to design new aeronautic combustors characterized by lean burn at relatively low temperatures. This requirement can easily cause flame instability phenomena and consequent pressure pulsations which may seriously damage combustor’s structure and/or compromise its fatigue life.
Hence the need to study the combustor’s structural dynamics and the interaction between elastic, thermal and acoustic phenomena. Finite element method represent a largely used and fairly reliable tool to address these studies; on the other hand, the idealization process may bring to results quite far from the reality whereas too simplifying assumptions are made.
Constraints modelling represent a key-issue for all dynamic FE analyses; a wrong simulation of the constraints may indeed compromise entire analyses although running on very accurate and mesh-refined structural models.
In this paper, a probabilistic approach to characterize the influence of external constraints on the modal behaviour of an aircraft combustor-rig is presented. The finite element model validation was performed at first by comparing numerical and experimental results for the free-free condition (no constraints). Once the model was validated, the effect of constraints elasticity on natural frequencies was investigated by means of a probabilistic design simulation (PDS); referring to a specific tool developed in the ANSYS®software, a preliminary statistical analysis was at performed via Monte-Carlo Simulation (MCS) method. The results were then correlated with the experimental ones via Response Surface Method (RSM).
