Published: March 2013

AbstractBackgroundNeuropathic deformities impair foot and ankle joint mobility, often leading to abnormal stresses and impact forces. The purpose of our study was to determine differences in radiographic measures of hind foot alignment and ankle joint and subtalar joint motion in participants with and without neuropathic midfoot deformities and to determine the relationships between radiographic measures of hind foot alignment to ankle and subtalar joint motion in participants with and without neuropathic midfoot deformities.MethodsSixty participants were studied in three groups. Forty participants had diabetes mellitus (DM) and peripheral neuropathy (PN) with 20 participants having neuropathic midfoot deformity due to Charcot neuroarthropathy (CN), while 20 participants did not have deformity. Participants with diabetes and neuropathy with and without deformity were compared to 20 young control participants without DM, PN or deformity. Talar declination and calcaneal inclination angles were assessed on lateral view weight bearing radiograph. Ankle dorsiflexion, plantar flexion and subtalar inversion and eversion were assessed by goniometry.ResultsTalar declination angle averaged 34±9, 26±4 and 23±3 degrees in participants with deformity, without deformity and young control participants, respectively (p< 0.010). Calcaneal inclination angle averaged 11±10, 18±9 and 21±4 degrees, respectively (p< 0.010). Ankle plantar flexion motion averaged 23±11, 38±10 and 47±7 degrees (p<0.010). The association between talar declination and calcaneal inclination angles with ankle plantar flexion range of motion is strongest in participants with neuropathic midfoot deformity. Participants with talonavicular and calcaneocuboid dislocations result in the most severe restrictions in ankle joint plantar flexion and subtalar joint inversion motions.ConclusionsAn increasing talar declination angle and decreasing calcaneal inclination angle is associated with decreases in ankle joint plantar flexion motion in individuals with neuropathic midfoot deformity due to CN that may contribute to excessive stresses and ultimately plantar ulceration of the midfoot.

Published: March 2013

AbstractInter-Vehicle Communication (IVC) is an important component of the ITS architecture, that enables Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. GeoNet project brought the IVC one step further by enabling transparent IP connectivity between vehicles and the infrastructure. Specifications produced by the GeoNet project have been incorporated into several ETSI standards, which define the geonetworking protocol layer and the IPv6-over-geonetworking adaptation layer. In this paper, we propose an ETSI complaint geonetworking protocol layer on the well known NCTUns simulation framework. We discuss the architecture of our implementation as well as NCTUns specific issues encountered during the implementation. We believe that, with this contribution, the researchers are provided with a scalable and flexible framework with Berkeley socket API access to applications and SQL based performance logging for post simulation evaluations.

Abstract
To study the D-genome of the wild wheat relative Aegilops tauschii Cosson at the hexaploid level, we developed a synthetic doubled-haploid (DH) hexaploid wheat population, SynDH3. This population was derived from the spontaneous chromosome doubling of triploid F1 hybrid plants obtained from a cross between Triticum turgidum ssp. dicoccon PI377655 and A. tauschii ssp. strangulata AS66 × ssp. tauschii AS87. SynDH3 is a diploidization-hexaploid DH population containing recombinant D chromosomes from two different A. tauschii genotypes, with A and B chromosomes from T. turgidum being homogenous across the entire population. Using this population, we constructed a genetic map. Of the 440 markers used to construct the map, 421 (96%) were assigned to 12 linkage groups; these included 346 Diversity Arrays Technology (DArT) and 75 simple sequence repeat (SSR) markers. The total map length of the seven D chromosomes spanned 916.27 cM, with an average length of 130.90 cM per chromosome and an average distance between markers of 3.47 cM. Seven segregation distortion regions were detected on seven linkage groups. Out of 50 markers shared with those on a common wheat map, 37 showed a consistent order. The utility of the diploidization-hexaploid DH population for mapping qualitative trait genes was confirmed using the dominant glaucousness-inhibiting gene W2

Published: March 2013

Abstract
Unusually small carbon nanoparticles were synthesized in a microwave plasma flow-reactor by pyrolysis of 0.3–1.2% CH4, C2H4, and C2H2 with 0.3–3.6% addition of molecular hydrogen in argon. Final particle sizes were analyzed by in-line particle-mass spectrometry (PMS) and by transmission electron microscopy (TEM). TEM measurements of primary particle sizes were found to be in a good agreement with PMS data. The carbon particles formed in the plasma generated by a 2.45 GHz magnetron with an applied power of 180 W and a total pressure of 13 mbar have diameters of 4–6 nm. The type of hydrocarbon precursor and 0.3–3.6% of hydrogen addition did not noticeably influence the final particle sizes. The formation of such small particles is attributed to the low pressure and the comparably low operation power. This method of small carbon nanoparticles synthesis could be useful for the production of carbon black material, where large surface area is important.

Abstract
The aggregational and adsorption behavior of an important antidepressant amphiphilic drug amitriptyline hydrochloride have been studied in the presence of nonionic surfactants at different temperatures by tensiometry. By using regular solution theory and other thermodynamic models, different physicochemical properties such as critical micellar concentration, micellar composition, interfacial adsorption, energetic parameters (free energy, enthalpy, entropy) of micellization are evaluated. The data clearly depict that there is strong interaction between the amitriptyline hydrochloride and nonionic surfactants. Steric factor appears to play an important role during interaction when surfactant molecular structure varies in size of the head group and chain length of the hydrophobic part. The temperature has been observed to be vital in controlling the dehydration and thermal solubility which, in turn, makes environment conducive for aggregational behavior of the drug-surfactant mixtures in aqueous solution.

ABSTRACTThe work takes advantage of a newly developed measurement system which enables to investigate the thermodynamic properties of thin films including battery layer sequences. This technique, Thin-Film Calorimetry (TFC), is based on the detection of resonance frequency shifts of bulk acoustic wave resonators. Thin films with a thickness of several micrometers of the material of interest are deposited on the resonators. By measuring the temperature dependent shift of the resonance frequency, the device is working as a precise temperature sensor. The production or consumption of latent heat by the active layer(s) results in temperature fluctuations with respect to the furnace where the sensor is placed. Those information enable to extract the temperature and time dependence of phase transformations as well as the associated enthalpies. To cover a temperature range from -20 to 900 °C high-temperature stable piezoelectric resonators made of langasite crystals (La3Ga5SiO14) are applied.Initially, metallic layers of tin and aluminum are used to test and verify this approach. The temperatures and enthalpies of solid-liquid as well as of solid-solid phase transformation are observed in the correct manner. Further, the thermodynamic data of the battery materials Li(Ni0.8Co0.15Al0.05)O2-δ (NCA) and LiMn2O4-δ (LMO) obtained by TFC are determined and discussed. Both cathode materials are amorphous after deposition and show crystallization during heating at 460 °C (NCA) and 600 °C (LMO). The associated enthalpies are 5.3 kJ/mol (55 J/g) and 17.3 kJ/mol (96 J/g), respectively.

ABSTRACTHighly ion-conductive Li6PS5Cl Li-argyrodites were prepared through a high energy ball milling. Electrical and electrochemical properties were investigated. Ball-milled compounds exhibit a high conductivity of 1.33×10−4S/cm with an activation energy of 0.3-0.4 eV and an electrochemical stability up to 7V vs. lithium. These results are obtained after only 10 hours of milling and with no additional heat treatment.To validate the use of the Li6PS5Cl-based solid electrolyte, all-solid-state batteries using LiCoO2and Li4Ti5O12as active material have been realized. The optimization of the electrode composition led to a maximum of 46 and 27 mAh per gram of composite for LiCoO2and Li4Ti5O12-based half-cells respectively. The assembled all-solid-state LiCoO2/ Li6PS5Cl / Li4Ti5O12battery presents a sustainable reversible capacity of 27 mAh per gram of active material and a coulomb efficiency close to 99%.
A suitable methodology for assessing impacts of successive rainfalls infiltration on road slope stability
Authors: Rameau Hugues Georges , Prepetit Claude , Verbrugge Jean-Claude 
Published: March 2013

Abstract
Water precipitation in road slopes, pavements, and shoulders may cause disturbances such as erosion, increase of the water table level, decrease of the carriageway bearing capacity, and so on. Roads are normally equiped with drainage systems that are sized and implemented in accordance with the rules of art. These equipments are used for the collection and quick evacuation of water precipitation estimated on the basis of the return period that is taken into account. Despite that, rainwater can still infiltrate unprotected cut or fill slopes, and pavements for repeated and intense rainfalls, which may cause a raise in pore-water pressure and a decrease of the factor of safety of road slopes. Using laboratory rainfall simulation techniques, infiltration measurements were made on intact samples to determine with respect to soil properties, how cumulative rainfalls cause decrease in apparent cohesion and lead to slope failure. This paper focuses on describing the relationship between the rainfall characteristics, the changes in soil water profile, and the changes in apparent cohesion for sandy clay samples collected on the national road RN3 located in Haiti. For a set of consecutive rainfall events at around an interval of 24 hours, the results prove that when wetting front depth approaches 2 meters or more, the risk of landslide is proportionally high in a soil with apparent cohesion (Ca) initially high and an effective cohesion (c′) relatively low.
Seismic anisotropy beneath the northeastern Caribbean: implications for the subducting North American lithosphere
Authors: Meighan Hallie E. , Pulliam Jay 
Published: March 2013

Abstract
Active plate boundaries in the Caribbean form a complex tectonic environment that includes transform and subduction zones. The Caribbean-North American plate boundary is one such active margin, where subduction transitions from arc- to oblique-type off the northeast coast of Puerto Rico. Understanding mantle flow in this region will not only help determine the nature of tectonic activity and mantle dynamics that control these margins, but will also aid our understanding of the fate of subducting lithosphere.
The existence of tears, windows, and gaps in subducting slabs has been proposed at various locations around the world but few have been confirmed. Since mantle flow and crustal deformation are believed to produce seismic anisotropy in the asthenosphere and lithosphere, searching for changes in, for example, SKS splitting parameters can help identify locations at which subducting slabs have been disrupted.
Several lines of evidence support the notion of a slab tear within the subducting North American plate at this transition zone, including the counter-clockwise rotation of the Puerto Rico microplate over the past ~10 Ma, clusters of small seismic events, and trench collapse initiating ~3.3 m.y. Here we present results from a detailed investigation of seismic anisotropy from 28 stations across six networks in the Northeast Caribbean that support the hypothesis of a significant slab gap in the vicinity of the U.S. and British Virgin islands.
A regional synthesis of our results reveals fast shear wave polarizations that are generally oriented parallel to the plate boundary with intermediate to high SH-SV delay times. For example, polarization directions are oriented roughly NE-SW along the bulk of the Lesser Antilles, E-W along the Puerto Rico trench and the northern Lesser Antilles, and NW-SE beneath Hispaniola. Beneath the U.S. and British Virgin Islands, however, the fast polarization direction differs markedly from the regional pattern, becoming almost perpendicular to the plate boundary. Stations on Anegada, British Virgin islands and St. Croix, U.S. Virgin islands show a fast polarization direction that is oriented nearly NNE-SSW and smaller delay times than surrounding stations. These results suggest that mantle flow is redirected NE-SW at this location through a gap in the subducted lithosphere of the North American plate.

Abstract
Atom-to-molecule conversion by the technique of optical Feshbach resonance in a magnetic lattice is studied in the mean-field approximation. For the case of a shallow lattice, we give the dependence of the atomto-molecule conversion efficiency on tunnelling strength and atomic interaction by taking a double-well as an example. We find that one can obtain a high atom-to-molecule conversion by tuning the tunnelling and interaction strengths of the system. For the case of a deep lattice, we show that the existence of the lattice can improve the atom-to-molecule conversion for certain initial states.
Analysis of two colliding fractionally damped spherical shells in modelling blunt human head impacts
Authors: Rossikhin Yury , Shitikova Marina 
Published: March 2013

AbstractThe collision of two elastic or viscoelastic spherical shells is investigated as a model for the dynamic response of a human head impacted by another head or by some spherical object. Determination of the impact force that is actually being transmitted to bone will require the model for the shock interaction of the impactor and human head. This model is indended to be used in simulating crash scenarios in frontal impacts, and provide an effective tool to estimate the severity of effect on the human head and to estimate brain injury risks. The model developed here suggests that after the moment of impact quasi-longitudinal and quasi-transverse shock waves are generated, which then propagate along the spherical shells. The solution behind the wave fronts is constructed with the help of the theory of discontinuities. It is assumed that the viscoelastic features of the shells are exhibited only in the contact domain, while the remaining parts retain their elastic properties. In this case, the contact spot is assumed to be a plane disk with constant radius, and the viscoelastic features of the shells are described by the fractional derivative standard linear solid model. In the case under consideration, the governing differential equations are solved analytically by the Laplace transform technique. It is shown that the fractional parameter of the fractional derivative model plays very important role, since its variation allows one to take into account the age-related changes in the mechanical properties of bone.

ABSTRACTBackgroundAcinic cell carcinoma (ACC) is a relatively rare and slowly growing tumor of the major salivary glands, usually arising from the parotid and rarely from the submandibular and sublingual salivary glands. ACC accounts for 3 to 4% of parotid tumors, 2 to 6% of all salivary gland tumors and 10 to 17% of all malignant salivary gland tumors.Case reportA 40-year-old woman reported a slow growing mass in the oral cavity. The transoral aspiration biopsy was reported as pleomorphic adenoma arising from the minor salivary glands of the junctional zone of base of tongue. Rest of the neck examination was normal and magnetic resonance imaging (MRI) revealed the mass confined to the superficial layers of the tongue without invasion.InterventionThe tumor was resected transorally with adequate margins. The tumor histology was typical of ACC with the margins free and wide on all the sides. The patient was kept on monthly follow-up where palpable nodes developed during the course of 6 months. The neck was addressed with supraomohyoid dissection and followed up without irradiation.ConclusionACC is a low-grade malignant salivary neoplasm rarely diagnosed in minor salivary glands of the oral cavity. The overall prognosis after surgical resection depends on the extent of lesion and the adequacy of the initial resection. Hence, keeping in mind the malignant potential of the disease careful long-term follow-up is advised.How to cite this articleNaik SM, Kudpaje A, Gupta S, Nanjundappa A, Halkud R, Prashanth V, Biswas S.

ABSTRACTLipomas in the oral cavity are rare benign soft tissue mesenchymal neoplasms, representing1% of all benign oral tumors. Very few cases of tonsillar lipoma have been reported in the English literature. The diagnosis and differentiation of lipoma with clinically similar lesions, such as squamous papilloma, adenomas, chondromas, hamartomas and teratomas, is essential for correct treatment management and follow-up. We describe a rare case of palatine tonsil lipoma in a 67-year-old female and an updated review of the sparse English literature.How to cite this articleAbu-Ghanem S, Zilker V, Trejo L, Fliss DM.

ABSTRACTAimTo elucidate the concentration of the protein and cholesterol in different fractions of human semen from different infertile categories and comparing them with the fertile group.Materials and methodsThe human semen was collected from different infertile categories including oligoasthenospermia, asthenospermia, azoospermia, normospermia, oligospermia and fertile group. Immediately after collection, the semen analysis was done as per WHO standard protocols. After that, the semen was centrifuged to get the different fractions. Four main fractions were obtained, (1) spermatozoa, (2) debris or material that precipitates at 12 K rpm for 10 minutes, (3) prostasomes which was precipitated at 20K rpm for 120 minutes, (4) seminal plasma. The protein concentration was done by Lowry's method and cholesterol was estimated by diagnostic kit.ResultsSodium dodecyl sulfate—polyacrylamide gel electrophoresis (SDS PAGE) was run for all the categories of semen samples for their seminal plasma and the fertility associated protein was identified. A significant difference was found in the concentration of proteins in all subfractions when compared between control and infertile categories. Almost 86% of the protein was recovered from soluble fraction. In case of azoospermia, the protein content was very low when compared with fertile group. Seminal plasma proteins were visualized by silver staining. The molecular weight of the protein bands were ranging from 6.5 to 205 kDa. The band with molecular weight around 55 kDa was found to be missing in case of oligoasthenospermia. This particular protein is said to be fertility associated protein. The content of cholesterol for different subfraction of the human semen samples from infertile and fertile samples was compared. A wide range of cholesterol was recovered from prostasomes, that too purified.ConclusionA thrive study have to be done in all the subfractions of the semen irrespective of the category of samples to know the exact function of the each subfractions in terms of protein and cholesterol distribution.How to cite this articleSundaram V, Srinivas MS, Rao KA, Pathy MR, Sridharan TB.
