Published: June 2014

Minimally invasive surgery revolutionized operative procedures in the last 20 years. Much of the progress in minimally invasive surgery can be attributed to the development of robot-based systems. The most apparent changes are found in laparoscopy procedures. Procedures in which only small skin incisions are made have revolutionized operating theaters. The learning curve, although long in itself, allows for the development of procedures with reduced perioperative risk (i.e., bleeding, pain) or shorter postoperative period. Convalescence after endoscopy procedures is significantly shorter compared with classic laparotomy. However, certain limitations apply to laparoscopy. Apart from the long learning curve, movements executed with long and rigid tools cannot strictly translate the precision of an operator’s hand. The body position of the surgeon is often forced by the reach of the endoscope instrument. It is related to a significant physical load of personnel, especially during long operating procedures. For this reason, some therapeutic procedures are still executed using the laparotomy approach.
Remarks on Hamilton's Compactness Theorem for Ricci flow
Authors: Topping Peter M.
Published: June 2014

A fundamental tool in the analysis of Ricci flow is a compactness result of Hamilton in the spirit of the work of Cheeger, Gromov and others.
Roughly speaking it allows one to take a sequence of Ricci flows with uniformly bounded curvature and uniformly controlled injectivity radius, and extract a subsequence that converges to a complete limiting Ricci flow. A widely quoted extension of this result allows the curvature to be bounded uniformly only in a local sense. However, in this note we give a counterexample.

Derangements in cosets of primitive permutation groups
Authors: Pavelescu Andrei
Published: June 2014

Motivated by questions arising in connection with branched coverings of connected smooth projective curves over finite fields, we study the proportion of fixed-point free elements (derangements) in cosets of normal subgroups of primitive permutations groups. Using the Aschbacher–O'Nan–Scott Theorem for primitive groups to partition the problem, we provide complete answers for affine groups and groups which contain a regular normal nonabelian subgroup.
Evaluation of the long-term behavior of potential plutonium waste forms in a geological repository
Authors: Deissmann Guido , Neumeier Stefan , Brandt Felix , Modolo Giuseppe , Bosbach Dirk
Published: June 2014

Various candidate waste matrices such as nuclear waste glasses, ceramic waste forms and low-specification “storage” MOX have been considered within the current UK geological disposal program for the immobilization of separated civilian plutonium, in the case this material is declared as waste. A review and evaluation of the long-term performance of potential plutonium waste forms in a deep geological repository showed that (i) the current knowledge base on the behavior and durability of plutonium waste forms under post-closure conditions is relatively limited compared to HLW-glasses from reprocessing and spent nuclear fuels, and (ii) the relevant processes and factors that govern plutonium waste form corrosion, radionuclide release and total systems behavior in the repository environment are not yet fully understood in detail on a molecular level. Bounding values for the corrosion rates of potential plutonium waste forms under repository conditions were derived from available experimental data and analogue evidence, taking into account that the current UK disposal program is in a generic stage, i.e. no preferred host rock type or disposal concept has yet been selected. The derived expected corrosion rates for potential plutonium waste forms under conditions relevant for a UK geological disposal facility are in the range of 10-4 to 10-2 g m-2 d-1 and 10-5 to 10-4 g m-2 d-1 for borosilicate glasses, and generic ceramic waste forms, respectively, and ∼5·10-6 g m-2 d-1 for storage MOX. More realistic assessments of the long-term behavior of the waste forms under post-closure conditions would require additional systematic studies regarding the corrosion and leaching behavior under more realistic post-closure conditions, to explore the safety margins of the various potential waste forms and to build confidence in long-term safety assessments for geological disposal.
Incorporation of REE into Secondary Phase Studtite.
Authors: Palomo C. , Rodríguez N. , Iglesias E. , Nieto J. , Cobos J. , Quiñones J.
Published: June 2014

The formation of uranyl peroxide phases was identified as a corrosion product of spent fuel by Hanson et al [1]. The subsequent analysis of this phase showed that metastudtite retained 241Am, 237Np and 239Pu [2]. In this study, the retention of radionuclide Pu4+ and An3+, released from the spent fuel matrix into studtite structure, has been evaluated by the precipitation of studtite from uranyl dissolution with variable concentrations of REE (Th, Nd, Sm and Eu). Three different precipitation conditions parameters were studied: media of synthesis, time of synthesis and REE concentration. Synthesized phases were characterized by XRD and the cell parameter was calculated. The REE incorporation was determined by ICP-MS analysis. The results showed that studtite could incorporate 63% of Th in solution during its precipitation. Changes in the “a” cell parameter were identified. The results suggest that studtite coprecipitated with REE could play a role as a limiting for the REE mobility.
Long-Term Corrosion of Zircaloy Hull Waste under Geological Disposal Conditions: Corrosion Correlations, Factors Influencing Corrosion, Corrosion Test Data, and Preliminary Evaluation
Authors: Tanabe Hiromi , Sakuragi Tomofumi , Miyakawa Hideaki , Takahashi Ryota
Published: June 2014

The carbon-14 generated in Zircaloy (Zry) hull waste is considered an important radionuclide in the TRU waste geological disposal concept in Japan. Given that the metal Zry is highly corrosion-resistant in the anaerobic and low-temperature conditions of the repository, and that the C-14 release rate is assumed to be controlled by the corrosion rate, a variety of corrosion and leaching tests have been performed. However, since the Zry corrosion rate is extremely slow, it is not possible to predict long-term corrosion behavior through low-temperature corrosion tests conducted in a reasonable time period. A vast amount of testing has been conducted in the higher-temperature range of 523 to 633 K, and corrosion correlations have been obtained from these tests. Corrosion correlations have been used to predict the corrosion rate of Zry in a tuff repository. Long-term Zry autoclave corrosion data have been analyzed to develop new corrosion correlations. Extrapolating these correlations to a lower temperature range requires verification that the mechanisms do not change over the range of testing and extrapolation. Factors that influence corrosion rates under geological disposal conditions, such as material and environmental factors, should also be examined. Corrosion correlations, factors influencing corrosion rates, the results of corrosion and leaching tests, and a preliminary evaluation are discussed.
Open-Circuit Voltage Characteristics in Polyfluorene Based Photovoltaic Devices
Authors: Ramsdale Catherine M. , Arias Ana Claudia , MacKenzie J. Devin , Friend Richard H. , Greenham Neil C.
Published: June 2014

In this work the origin of the open-circuit voltage is studied in bi-layer devices based on polyfluorenes. The devices were fabricated using a lamination technique, which avoids the problems that usually arise when making well-defined bi-layers from soluble polymers. Often the open-circuit voltage in devices is attributed to the difference in the workfunctions of the electrodes. Whilst a cathode dependence of the open-circuit voltage was observed here, an additional constant voltage of ∼1V was also present in the devices investigated. We conclude that this additional open-circuit voltage is largely a result of a photo-induced dipole at the donoracceptor interface. This dipole is formed by charges that are separated as a result of exciton dissociation when the device is illuminated. Devices where the order of the polymer layers was reversed showed very different open-circuit voltages which confirms that the open-circuit voltage is heavily dependent on the structure of the active layer in the device. The effects of device thickness and excitation intensity on open-circuit voltage are also discussed.

Authors: Vale Beatriz , Brito Sara , Paulos Lígia , Moleiro Pascoal
Published: June 2014

Objective To analyse the progression of body mass index in eating disorders and to determine the percentile for establishment and resolution of the disease.Methods A retrospective descriptive cross-sectional study. Review of clinical files of adolescents with eating disorders.Results Of the 62 female adolescents studied with eating disorders, 51 presented with eating disorder not otherwise specified, 10 anorexia nervosa, and 1 bulimia nervosa. Twenty-one of these adolescents had menstrual disorders; in that, 14 secondary amenorrhea and 7 menstrual irregularities (6 eating disorder not otherwise specified, and 1 bulimia nervosa). In average, in anorectic adolescents, the initial body mass index was in 75thpercentile; secondary amenorrhea was established 1 month after onset of the disease; minimum weight was 76.6% of ideal body mass index (at 4th percentile) at 10.2 months of disease; and resolution of amenorrhea occurred at 24 months, with average weight recovery of 93.4% of the ideal. In eating disorder not otherwise specified with menstrual disorder (n=10), the mean initial body mass index was at 85thpercentile; minimal weight was in average 97.7% of the ideal value (minimum body mass index was in 52nd percentile) at 14.9 months of disease; body mass index stabilization occured at 1.6 year of disease; and mean body mass index was in 73rd percentile. Considering eating disorder not otherwise specified with secondary amenorrhea (n=4); secondary amenorrhea occurred at 4 months, with resolution at 12 months of disease (mean 65th percentile body mass index).Conclusion One-third of the eating disorder group had menstrual disorder − two-thirds presented with amenorrhea. This study indicated that for the resolution of their menstrual disturbance the body mass index percentiles to be achieved by female adolescents with eating disorders was 25-50 in anorexia nervosa, and 50-75, in eating disorder not otherwise specified.

Published: June 2014

Objective To validate the minimal criteria of the histopathologic diagnosis of oral chronic graft-versus-host disease, based on the histopathologic classification of the National Institutes of Health and correlate them with clinical features.Methods Forty-one specimens containing both oral mucosa and salivary glands were analyzed in slides stained with hematoxylin-eosin. The histological specimens were blindly examined by two trained pathologists using criteria recommended for the histopathologic diagnosis of chronic graft-versus-host disease proposed by the National Institutes of Health Consensus. The clinical classification of chronic graft-versus-host disease was correlated with analysis of slides. Results: Our data showed that the epithelium was involved in 39/41 specimens, presenting acanthosis (29/70.7%), exocytosis of lymphocytes (29/70.7%), thickening of basal lamina (29/70.7%), and apoptosis (15/36.6%). Connective tissue presented interstitial inflammatory infiltrate (38/92.7%). Minor salivary glands showed periductal fibrosis (38/92.7%), mixed periductal inflammatory infiltrate (32/78%), ductal ectasia (30/73.2%), lymphocytes around and into acinar units (30/73.2%), and interstitial fibrosis (29/70.7%). The most common clinical manifestations were lichenoid aspect (40/97.6%), complaints of sensitivity to oral feeding (38/92.7%), and dry mouth sensation (36/87.8%).Conclusion This study validated the National Institutes of Health Consensus of minimal histologic criteria for diagnosis of oral chronic graft-versus-host disease and has not found an association between the severity of clinical manifestation and the histopathological stage.

Published: June 2014

Improvement in the drought tolerance of the cool‐season perennial grass species creeping bentgrass (Agrostis stolonifera L.) has significant value within the turfgrass industry. Understanding genomic regions associated with quantitative trait loci (QTL) such as drought tolerance will allow for advancement of breeding strategies to identify creeping bentgrass germplasm with improved abiotic stress tolerance. A multiyear and multienvironment study was performed to identify QTL in a mapping population of creeping bentgrass segregating for phenotypic traits associated with drought tolerance. Phenotypic data was collected during two growth chamber studies and 2 yr of a field trial. The phenotypic traits that were measured included turf quality (TQ), relative water content (RWC), canopy temperature depression (CTD), osmotic adjustment (OA), electrolyte leakage (EL), chlorophyll content (CHL), water use efficiency (WUE), and the normalized difference vegetative index (NDVI). Quantitative trait loci were identified for all traits on both parental maps except for OA and EL. Quantitative trait loci were found within all linkage groups except for group 2 in both parents. The linkage group areas that had QTL with a significant amount of overlapping for multiple traits and trials included linkage group 5.2, 7.1, and 7.2 on the drought tolerant parent ‘L‐93’ and groups 4.2 and 7.2 on the drought sensitive parent 7418–3. These and other QTL identified in this study have potential to be used in future studies that aim to more closely identify the genes associated with these QTL areas and for further investigation of their potential for use in marker‐assisted selection practices.

Published: June 2014

Increasing the carotenoid concentration of pulse crop seeds is part of a biofortification strategy. The objective of this research was to evaluate the concentration and distribution of carotenoids in the seeds of twelve pea (Pisum sativum L.) cultivars and eight chickpea (Cicer arietinum L.) cultivars grown at multiple locations during 2 yr in Saskatchewan, Canada using high performance liquid chromatography (HPLC) with a diode array detector. Lutein was the major carotenoid in both crops, with mean lutein concentration ranging from 7.2 µg g−1 to 17.6 µg g−1 and 6.3 µg g−1 to 11.0 µg g−1 in pea and chickpea, respectively. Violaxanthin, zeaxanthin, and β‐carotene were also present in both crops. Green cotyledon pea cultivars had approximately twice as many total carotenoids (16–21 µg g−1) than yellow cotyledon pea cultivars (7–12 µg g−1). Cultivar had a greater effect than environment on carotenoid concentration in both crops. Location effects were significant for violaxanthin, lutein, and total carotenoid concentration for pea and for violaxanthin and zeaxanthin in chickpea. Year effect was significant for all carotenoids in pea and significant for β‐carotene in chickpea. The cultivar × location interaction was significant for violaxanthin in pea and chickpea and for lutein in pea. Among the three seed tissues, carotenoid concentration was greatest in the cotyledon followed by the embryo axis and seed coat in both crops. The results of this investigation should be useful for improving nutritional quality in pulse crops.
Local analysis of hybrid systems on polyhedral sets with state-dependent switching
Authors: Leth John , Wisniewski Rafael
Published: June 2014

This paper deals with stability analysis of hybrid systems. Various stability concepts related to hybrid systems are introduced. The paper advocates a local analysis. It involves the equivalence relation generated by reset maps of a hybrid system. To establish a tangible method for stability analysis, we introduce the notion of a chart, which locally reduces the complexity of the hybrid system. In a chart, a hybrid system is particularly simple and can be analyzed with the use of methods borrowed from the theory of differential inclusions. Thus, the main contribution of this paper is to show how stability of a hybrid system can be reduced to a specialization of the well established stability theory of differential inclusions. A number of examples illustrate the concepts introduced in the paper.
Preliminary Studies on Simultaneous Recovery of Precious Metals from Different Waste Materials by Pyrometallurgical Method
Authors: Willner J. , Fornalczyk A. , Cebulski J. , Janiszewski K.
Published: June 2014

Automotive catalytic converters have a limited life time, after which the catalyst must be replaced or regenerated. The spent catalytic converters contain small amount of precious metals. Recovery of these metals is essential for environmental and economic reasons. The waste electronic equipment is also an attractive source for recovery of precious metals. Precious metals in electronic scraps are concentrated mainly in printed circuits and integrated circuits - so generally in elements that are the most diverse in their composition. Material heterogeneity of these elements is the reason why there is no universal method for processing this type of scrap. Methods used in the world for recovery of precious metals from spent auto catalytic coverters and electronic wastes by pyrometallurgical and hydrometallurgical methods were mentioned in this paper. The results of simultaneous melting of electronic waste with spent automotive catalysts were presented. The printed circuit boards were used as the carrier and as a source of copper. The precious metals present in the catalyst were collected in copper.
Normalized Expected Utility-Entropy Measure of Risk
Authors: Yang Jiping , Qiu Wanhua
Published: June 2014

Yang and Qiu proposed an expected utility-entropy (EU-E) measure of risk, which reflects an individual’s intuitive attitude toward risk. Luce et al. have derived the numerical representations under behavioral axioms about preference orderings among gambles and their joint receipt, which further demonstrates the reasonability of the EU-E decision model as a normative one. In the paper, combining normalized expected utility and entropy together, we improve the EU-E measure of risk and decision model, and then propose the normalized EU-E measure of risk and decision model. The normalized EU-E measure of risk has some normative properties under certain conditions. Moreover, the normalized EU-E decision model can be a proper descriptive model to some extent. Using this model, two cases of common ratio effect and common consequence effect, which are the examples of certainty effects, can be explained in an intuitive way.
Amino Acid Composition of an Organic Brown Rice Protein Concentrate and Isolate Compared to Soy and Whey Concentrates and Isolates
Authors: Kalman Douglas
Published: June 2014

A protein concentrate (Oryzatein-80™) and a protein isolate (Oryzatein-90™) from organic whole-grain brown rice were analyzed for their amino acid composition. Two samples from different batches of Oryzatein-90™ and one sample of Oryzatein-80™ were provided by Axiom Foods (Los Angeles, CA, USA). Preparation and analysis was carried out by Covance Laboratories (Madison, WI, USA). After hydrolysis in 6-N hydrochloric acid for 24 h at approximately 110 °C and further chemical stabilization, samples were analyzed by HPLC after pre-injection derivitization. Total amino acid content of both the isolate and the concentrate was approximately 78% by weight with 36% essential amino acids and 18% branched-chain amino acids. These results are similar to the profiles of raw and cooked brown rice except in the case of glutamic acid which was 3% lower in the isolate and concentrate. The amino acid content and profile of the Oryzatein-90™ isolate was similar to published values for soy protein isolate but the total, essential, and branched-chain amino acid content of whey protein isolate was 20%, 39% and 33% greater, respectively, than that of Oryzatein-90™. These results provide a valuable addition to the nutrient database of protein isolates and concentrates from cereal grains.
Climate Change and Virtue: An Apologetic
Authors: Hulme Mike
Published: June 2014

The prominent Australian earth scientist, Tim Flannery, closes his recent book Here on Earth: A New Beginning with the words “… if we do not strive to love one another, and to love our planet as much as we love ourselves, then no further progress is possible here on Earth”. This is a remarkable conclusion to his magisterial survey of the state of the planet. Climatic and other environmental changes are showing us not only the extent of human influence on the planet, but also the limits of programmatic management of this influence, whether through political, economic, technological or social engineering. A changing climate is a condition of modernity, but a condition which modernity seems uncomfortable with. Inspired by the recent “environmental turn” in the humanities—and calls from a range of environmental scholars and scientists such as Flannery—I wish to suggest a different, non-programmatic response to climate change: a reacquaintance with the ancient and religious ideas of virtue and its renaissance in the field of virtue ethics. Drawing upon work by Alasdair MacIntyre, Melissa Lane and Tom Wright, I outline an apologetic for why the cultivation of virtue is an appropriate response to the challenges of climate change.
Supraspliceosomes at Defined Functional States Portray the Pre-Assembled Nature of the Pre-mRNA Processing Machine in the Cell Nucleus
Authors: Kotzer-Nevo Hani , De Lima Alves Flavia , Rappsilber Juri , Sperling Joseph , Sperling Ruth
Published: June 2014

When isolated from mammalian cell nuclei, all nuclear pre-mRNAs are packaged in multi-subunit large ribonucleoprotein complexes—supraspliceosomes—composed of four native spliceosomes interconnected by the pre-mRNA. Supraspliceosomes contain all five spliceosomal U snRNPs, together with other splicing factors, and are functional in splicing. Supraspliceosomes studied thus far represent the steady-state population of nuclear pre-mRNAs that were isolated at different stages of the splicing reaction. To analyze specific splicing complexes, here, we affinity purified Pseudomonas aeruginosa phage 7 (PP7)-tagged splicing complexes assembled in vivo on Adenovirus Major Late (AdML) transcripts at specific functional stages, and characterized them using molecular techniques including mass spectrometry. First, we show that these affinity purified splicing complexes assembled on PP7-tagged AdML mRNA or on PP7-tagged AdML pre-mRNA are assembled in supraspliceosomes. Second, similar to the general population of supraspliceosomes, these defined supraspliceosomes populations are assembled with all five U snRNPs at all splicing stages. This study shows that dynamic changes in base-pairing interactions of U snRNA:U snRNA and U snRNA:pre-mRNA that occur in vivo during the splicing reaction do not require changes in U snRNP composition of the supraspliceosome. Furthermore, there is no need to reassemble a native spliceosome for the splicing of each intron, and rearrangements of the interactions will suffice.
Characterization of ACE Inhibitory Peptides from Mactra veneriformis Hydrolysate by Nano-Liquid Chromatography Electrospray Ionization Mass Spectrometry (Nano-LC-ESI-MS) and Molecular Docking

Published: June 2014

Food-derived bioactive compounds are gaining increasing significance in life sciences. In the present study, we identified angiotensin I-converting enzyme (ACE)-inhibitory peptides from Mactra veneriformis hydrolysate using a nano-LC-MS/MS method. Mactra veneriformis hydrolysate was first separated into four fractions (F1–F4) based on molecular weight by ultrafiltration. The fraction with molecular weight lower than 1 kDa (F1) showed the highest ACE inhibitory activity. F1 was then analyzed by a high throughput nano-LC-MS/MS method and sequences of peptides in F1 were calculated accordingly. The 27 peptides identified as above were chemically synthesized and tested for ACE-inhibitory activity. The hexapeptide VVCVPW showed the highest potency with an IC50 value of 4.07 μM. We then investigated the interaction mechanism between the six most potent peptides and ACE by molecular docking. Our docking results suggested that the ACE inhibitory peptides bind to ACE via interactions with His383, His387, and Glu411 residues. Particularly, similar to the thiol group of captopril, the cysteine thiol group of the most potent peptide VVCVPW may play a key role in the binding of this peptide to the ACE active site.
Perturbation of the Human Microbiome as a Contributor to Inflammatory Bowel Disease
Authors: Missaghi Bayan , Barkema Herman , Madsen Karen , Ghosh Subrata
Published: June 2014

The human microbiome consist of the composite genome of native flora that have evolved with humanity over millennia and which contains 150-fold more genes than the human genome. A “healthy” microbiome plays an important role in the maintenance of health and prevention of illness, inclusive of autoimmune disease such as inflammatory bowel disease (IBD). IBD is a prevalent spectrum of disorders, most notably defined by Crohn’s disease (CD) and ulcerative colitis (UC), which are associated with considerable suffering, morbidity, and cost. This review presents an outline of the loss of a normal microbiome as an etiology of immune dysregulation and IBD pathogenesis initiation. We, furthermore, summarize the knowledge on the role of a healthy microbiome in terms of its diversity and important functional elements and, lastly, conclude with some of the therapeutic interventions and modalities that are now being explored as potential applications of microbiome-host interactions.
ANALYSIS OF THE EFFECT OF TWO-WHEELER LANE-SHARING BEHAVIOR ON MACROSCOPIC TRAFFIC FLOW MODELING
Authors: Chunchu Mallikarjuna , Kuzhiyamkunnath Bhavathrathan Bhattiyil
Published: June 2014

Small size motorized vehicles such as the motorized two-wheelers are predominantly present in the traffic observed in the developing countries. Presence of these smaller vehicles invalidates the concept of lane discipline commonly observed in the homogeneous traffic streams. In this paper an attempt has been made to understand the Motorized Two-Wheeler (MTW) lane-sharing behavior and its effects on traffic flow modeling. The objectives of this attempt are to analyze the lane-sharing behavior of MTWs at microscopic and macroscopic level, and to propose a methodology to incorporate this behavior in the macroscopic modeling concepts. Effect of the MTW lane-sharing behavior on the microscopic and macroscopic traffic characteristics and the corresponding models is discussed. A plausible way to incorporate this behavior, specifically in macroscopic modeling, is discussed. From a specific analysis based on VISSIM (version 5.20) it has been observed that the MTW lane-sharing behavior significantly influence the equilibrium speed-density relationships which are the key inputs to the macroscopic traffic flow models. Density diminishing factor is found to be significantly influenced by the proportion of MTWs present in the traffic stream. It has been observed that the lane-sharing behavior starts taking place when the average stream speed is less than 65 km/hr, for the proportions of MTWs in between 25 to 60%. For further higher MTW proportions lane-sharing has been observed even in free flow conditions.
A DATA MINING APPROACH TO FORECAST LATE ARRIVALS IN A TRANSHIPMENT CONTAINER TERMINAL
Authors: Pani Claudia , Fadda Paolo , Fancello Gianfranco , Frigau Luca , Mola Francesco
Published: June 2014

One of the most important issues in Transhipment Container Terminal (TCT) management is to have fairly reliable and affordable predictions about vessel arrival. Terminal operators need to estimate the actual time of arrival in port in order to determine the daily demand for each work shift with greater accuracy. In this way, the resources required (human resources, equipment as well as spatial resources) can be allocated more efficiently. Despite contractual obligations to notify the Estimated Time of Arrival (ETA) 24 hours before arrival, ship operators often have to revise it due to unexpected events like weather conditions, delay in a previous port and so on. For planners the decision-making processes related to this topic can sometimes be so complex without the support of suitable methodological tools. Specific models should be adopted, in a daily planning scenario, to provide a useful support tool in TCTs. In this study, we discuss an exploratory analysis of the data affecting delays registered at a Mediterranean TCT. We present some preliminary results obtained using data mining techniques and propose a Classification and Regression Trees (CART) model to reduce the range of uncertainty of ship arrivals in port. This approach is compulsory to manage vast amounts of unstructured data involved in estimating of vessel arrivals.
AN EMPIRICAL MODELLING FRAMEWORK FOR FORECASTING FREIGHT TRANSPORTATION
Authors: Güler Hakan
Published: June 2014

This paper presents a framework which includes empirical modelling methods to estimate freight transportation between defined zones. In this method, observed origin and destination matrices for each type of freight are constituted based on the link counts and the roadside truck survey data. The gravity method is selected to estimate origin and destination matrices by using observed link flows, gross domestic product by provinces and interzonal distances. Advanced statistical techniques and regression analyses are used to estimate the coefficients of the gravity method. The final freight transportation matrix is calibrated with the link flows data by using iterative techniques. The developed method was applied to find the origin and destination matrix of the total freight transportation in Turkey and successful results were obtained.

Opinion Mining or Sentiment Analysis is the study that analyzes people's opinions or sentiments from the text towards entities such as products and services. It has always been important to know what other people think. With the rapid growth of availability and popularity of online review sites, blogs', forums', and social networking sites' necessity of analysing and understanding these reviews has arisen. The main approaches for sentiment analysis can be categorized into semantic orientation-based approaches, knowledge-based, and machine-learning algorithms. This chapter surveys the machine learning approaches applied to sentiment analysis-based applications. The main emphasis of this chapter is to discuss the research involved in applying machine learning methods mostly for sentiment classification at document level. Machine learning-based approaches work in the following phases, which are discussed in detail in this chapter for sentiment classification: (1) feature extraction, (2) feature weighting schemes, (3) feature selection, and (4) machine-learning methods. This chapter also discusses the standard free benchmark datasets and evaluation methods for sentiment analysis. The authors conclude the chapter with a comparative study of some state-of-the-art methods for sentiment analysis and some possible future research directions in opinion mining and sentiment analysis.

Effect of Hydrothermal Aging on the Phase Stability, Microstructure and Mechanical Properties of Dental 3Y-TZP Ceramics
Authors: Wu Zhi Kai , Li Ning , Yan Jia Zhen , Zhao Wan Qian
Published: June 2014

An in vitro study was conducted to study the effect of hydrothermal aging on the phase stability, microstructure and mechanical properties of dental 3Y-TZP ceramics. It’s found that dental 3Y-TZP showed a time-dependent tetragonal to monoclinic phase transformation during aging. This transformation resulted in an increase of the mechanical properties at the initial stage of aging, probably due to the generated superficial compressive stress. However, once the stress became large enough to cause severe grain fall off, micro-crackings and surface flaws, the mechanical properties of dental 3Y-TZP started to drop drastically. Dental 3Y-TZPs doped with Al2O3and sintered at low temperatures showed improved aging resistance.

Published: June 2014

In this paper, a detailed comparison of axi-symmetric and 3D pipe finite element models was carried out under the condition of same welding simulation parameters. Results showed that axi-symmetric model share similar residual stress distribution with 3D model in the condition of same heat source shape parameters. However, the stress values of the two concerned models were different. Meanwhile the scale of welding pool for 3D model was almost twice bigger than that of axi-symmetric model. Both welding experiment and simulation results of 3D model showed that peak temperature of welding pool along the welding path increased during the welding process, and welding pool width and depth also increased with the moving of heat source.
