Authors: Jabeen Salma , Khurshiduzzaman -
Published: July 2016

Objectives : The purpose of the present study was to asses the incidence and severity of pain after single and two visit Root Canal Treatment ( RCT ) / endodontic treatment in asymptomatic non vital single rooted maxillary teeth.Methods : Eighty one cases of endodontically involved asymptomatic, non vital, single rooted maxillary teeth without evidence of periapical radiolucency in radiograph were selected for this study. The patient were divided into two treatment group. In single visit group, all teeth were prepared and filled using the standardized preparation and lateral condensation filling technique. In the two visit treatment group, at the first appointment, the teeth were prepared and dressed with calcium hydroxide paste for 7 days. At the second appointment, the teeth were prepared and obturated by using lateral condensation technique. The frequency of post obturation pain was recorded as no pain, slight/ mild, moderate and severe pain and evaluated at the day 1 and at the day 7 after obturation. The data were analyzed statistically by using SPSS version 16. p-value <0.05 was taken as significant.Results : No significant difference in post obtuation pain was found in between single and two visit RCT in maxillary teeth. At the day 1 and 7 after obturation, single visit (n= 41) group and two visit (n=40) group similarly experienced moderate pain (2.5% and 1.1% respectively in both group). At day 1 and 7 after obturation, mild pain is more in single visit than two visit group. However, there was no statistically significant difference in pain between the two groups. No one experienced severe pain in two groups.Conclusion: The incidence and severity of post obturation pain did not differ between single and two visit RCT in asymptomatic non vital single rooted maxillary teeth.Chatt  Shi Hosp Med Coll J; Vol.15 (1); Jan 2016; Page 45-48

Authors: Yeasmin Sabina , Begum Tahera , Uddin Md Jalal
Published: July 2016

Broad ligament pregnancy is an extremely rare event with high risk of maternal mortality. Diagnosis is often late in our setting and finally made during laparotomy. It is a type of secondary abdominal pregnancy.We present a case which remained undiagnosed throughout her pregnancy till she reached to 35 weeks and unfortunately had intrauterine fetal demise when she reported to our hospital.After admission her pregnancy was induced with misoprostol but did not response. On clinical suspicion,repeat ultrasound evaluation was done by senior sinologist, which picked up the diagnosis of abdominal pregnancy. On laparotomy a broad ligament pregnancy was found with a rent in the previous Cesarean scar towards the gestational sac in the broad ligament.Chatt  Shi Hosp Med Coll J; Vol.15 (1); Jan 2016; Page 60-62
Development of a Screening Tool for the Identification of Sacroiliitis in Computed Tomography Scans of the Abdomen
Authors: Chan Jonathan , Sari Ismail , Salonen David , Inman Robert D. , Haroon Nigil
Published: July 2016

Objective.

To develop a screening tool for the identification of sacroiliitis on abdominal computed tomography (CT) scan.

Methods.

Variables including erosions (number and size), sclerosis (depths of > 0.3 cm or > 0.5 cm), and ankylosis were identified through a training exercise involving 12 CT scans containing the sacroiliac joints. Two blinded readers read 24 CT scans from a derivation cohort to propose a screening tool for identifying discriminating features of sacroiliitis. A test cohort of 68 patients was used to confirm the utility of this tool. Inter- and intraobserver values, sensitivity, specificity, and positive/negative likelihood ratios were calculated for individual as well as combinations of variables. Erosions were evaluated using receiver-operating characteristic curves.

Results.

Analysis of the derivation cohort determined that counting the number of erosions on the worst coronal slice in each of 4 articular surfaces was not inferior to analyzing each individual slice in either transverse or coronal view. In the test cohort, interreader reliability for ankylosis and iliac and sacral erosions was very good (κ = 1, ICC = 0.989 and 0.995, respectively) whereas for sclerosis, it was moderate (κ = 0.39–0.96). A total erosion score of ≥ 3 was found to have the highest sensitivity and specificity for sacroiliitis (91% for each). The addition of a > 0.5 cm of iliac sclerosis or a > 0.3 cm of sacral sclerosis marginally increased the sensitivity (94%) but decreased specificity (85%).

Conclusion.

The presence of ankylosis or a total erosion score of ≥ 3 on CT is sufficient for identifying patients at high risk of sacroiliitis and may prompt more timely referrals to a rheumatologist.

Objective.

Apremilast, an oral phosphodiesterase 4 inhibitor, downregulates intracellular inflammatory mediator synthesis by elevating cyclic adenosine monophosphate levels. The PALACE 2 trial evaluated apremilast efficacy and safety in patients with active psoriatic arthritis (PsA) despite prior conventional disease-modifying antirheumatic drugs and/or biologic therapy.

Methods.

Eligible patients were randomized (1:1:1) to placebo, apremilast 20 mg BID, or apremilast 30 mg BID. At Week 16, patients with swollen and tender joint count improvement < 20% entered early escape, with placebo patients rerandomized (1:1) to apremilast 20 mg BID or 30 mg BID while apremilast patients continued on their initial apremilast dose. At Week 24, patients remaining on placebo were rerandomized to apremilast 20 mg BID or 30 mg BID. The primary endpoint was the proportion of patients achieving > 20% improvement in American College of Rheumatology response criteria (ACR20) at Week 16.

Results.

In the intent-to-treat population (N = 484), ACR20 at Week 16 was achieved by more patients receiving apremilast 20 mg BID [37.4% (p = 0.0002)] and 30 mg BID [32.1% (p = 0.0060)] versus placebo (18.9%). Clinically meaningful improvements in signs and symptoms of PsA, physical function, and psoriasis were observed with apremilast through Week 52. The most common adverse events were diarrhea, nausea, headache, and upper respiratory tract infection. Diarrhea and nausea generally occurred early and usually resolved spontaneously with continued treatment. Laboratory abnormalities were infrequent and transient.

Conclusion.

Apremilast demonstrated clinical improvements in PsA for up to 52 weeks, including signs and symptoms, physical function, and psoriasis. No new safety signals were observed. ClinicalTrials.gov identifier: NCT01212757.
Poids économique de la francophonie : impact via l’ouverture commerciale
Authors: Carrère Céline , Masood Maria
Published: July 2016

Dans cet article nous proposons d’analyser le rôle et l’importance de la langue française sur les flux commerciaux de biens par rapport aux autres types de proximité (géographique, historique, etc.) et de chiffrer son poids économique pour les pays de l’espace francophone (EF), en termes de flux commerciaux et, via le taux d’ouverture au commerce, en termes de PIB par tête et d’emploi. Ainsi, à l’aide d’un modèle de gravité estimé en panel, on constate qu’en moyenne un pays francophone bénéficie d’un supplément de commerce de 22 % avec un autre pays de cet espace, relativement au commerce qu’il aurait avec ce même pays s’il n’était pas francophone. Il apparaît également que l’effet sur le commerce dû au partage du français semble avoir été plus important durant la crise financière de 2008, suggérant que le partage d’une langue favorise l’existence de relations commerciales non seulement plus intenses mais également plus résilientes en période de crise. Une comparaison avec les autres principaux espaces linguistiques (anglophone, lusophone, hispanophone et arabophone) montre que l’impact global de l’appartenance à un espace sur le taux d’ouverture commerciale des pays est assez similaire. Au final, les retombées économiques de l’appartenance à un espace linguistique semblent en moyenne relativement faibles sur le PIB (mais il existe une grande hétérogénéité entre pays d’un même espace) et quasi inexistantes sur l’emploi.
Contraintes de financement et productivité dans l’industrie de l’habillement au Maroc en présence d’hétérogénéité de la technologie
Authors: Chaffai Mohamed E. , Plane Patrick
Published: July 2016

La relation entre l’accès au financement et la performance productive est étudiée sur un échantillon aléatoire de 324 entreprises marocaines sur une période de trois ans (2000-2002). Nous émettons l’hypothèse que les contraintes financières affectent potentiellement la productivité à travers le niveau d’efficacité technique ou le choix de la technologie. L’impact de ces deux phénomènes est étudié conjointement en utilisant les modèles de frontières stochastiques à classes latentes (LCSFM). En moyenne, la contribution de l’efficacité technique à la productivité s’avère limitée relativement à l’impact des choix technologiques. Si les entreprises étaient financièrement sans contrainte, le gain de productivité totale des facteurs (PTF) qui en résulterait permettrait de gagner de 18 % à 64 % d’efficacité. Dans toutes les catégories de tailles des entreprises, le gain le plus important est observé pour celles de moins de 20 salariés. Les résultats empiriques peuvent être qualifiés en considérant que les capacités humaines conditionnent également l’efficacité de la mise en œuvre d’une technologie. Compte tenu de leur capital humain, 22 % des entreprises semblent véritablement souffrir d’une perte de productivité inhérente aux défaillances des marchés financiers.
Du bilan mitigé des Objectifs du Millénaire pour le développement aux difficultés de mise en œuvre des Objectifs de développement durable
Authors: Hugon Philippe
Published: July 2016

Les OMD, pensés en termes d’objectifs sociaux à atteindre pour les seuls pays du Sud à l’horizon 2015, ne remettaient pas en cause les préférences collectives du Nord. Le passage des OMD aux ODD se situe dans un contexte où les questions planétaires, notamment climatiques, dominent les débats. La traduction des objectifs à atteindre en ressources à mobiliser et en résultats observables est particulièrement délicate pour un développement à la fois durable et inclusif. Cet article présente le bilan contrasté des OMD et traite des principaux enjeux des ODD dans un monde multipolaire et une financiarisation du capitalisme caractérisé par un déplacement de la richesse et de la puissance et la vulnérabilité d’une partie de la population.

Published: July 2016

Les Objectifs du Millénaire pour le développement sont une opérationnalisation du droit au développement. Dans cet article nous balayons l’historique du droit au développement et les principales critiques qui lui ont été portées. Nous montrons que ces critiques ont largement pu trouver réponse. Cependant, trois enjeux majeurs restent largement ouverts : la participation des populations, le droit des populations autochtones, et le droit à un environnement sain. La particularité de ces trois enjeux est d’ouvrir sur un débat opposant droit individuel inaliénable et droit collectif.

La Chine, les Objectifs du Millénaire pour le développement et la société de petite prospérité
Authors: Pairault Thierry
Published: July 2016

Malgré une apparente participation aux grandes opérations lancées par les organisations internationales comme celle des Objectifs du Millénaire pour le développement, la Chine est toujours restée sur son quant-à-soi, introduisant ses propres normes, élaborant ses propres objectifs et établissant son propre calendrier. C’est ainsi qu’elle a initié une stratégie en vue d’élaborer une société de petite prospérité s’opposant, dans une certaine mesure, à la vision de la Banque mondiale.

L’éthique théologique de langue italienne
Authors: Guenzi Pier Davide
Published: July 2016

L’article dresse un état des lieux de la théologie morale italienne, dont il présente trois dimensions fondamentales : sa manière d’« être présente » dans le débat ecclésial et civil contemporain (dimension « introspective »), les efforts qu’elle déploie pour « rapporter au présent » sa propre tradition de pensée (dimension « rétrospective »), et enfin, sa manière d’« adhérer au présent » afin d’ouvrir des horizons d’avenir (dimension « prospective »). À partir du chemin de l’éthique théologique italienne des derniers cinquante ans, l’article plaide pour un retour non naïf de la « casuistique », cette dernière étant comprise non seulement comme un point d’arrivée de la dynamique d’évaluation se penchant sur une situation donnée, mais comme un moment génétique de la normativité elle-même et de son processus évolutif.

Authors: border Regional Geography in times of , Junior Raimundo Nonato
Published: July 2016

O presente artigo aborda os desafios e oportunidades à Geografia Regional em tempos contemporâneos. O estudo foi realizado a partir de pesquisa de campo na fronteira franco-brasileira do Oiapoque, localizada entre o Estado do Amapá e o departamento ultramarino da Guiana Francesa, zona de forte tensão entre forças regionais e globais. No atual período de globalização econômica e informacional, as relações regionais ainda exercem forte papel na produção e uso do espaço, imbricadas a múltiplas categorias geográficas, escalas políticas e atores sociais. Então, a fronteira França-Brasil se revela como laboratório social privilegiado para observação dos limites e potências da Geografia Regional na atualidade, enfatizando a prática de conceitos como: complexo geográfico, região vivida e região em rede. A partir deste campo são traçadas considerações sobre a epistemologia contemporânea dos estudos regionais frente às tensões políticas internacionais e práticas humanas transnacionais em zonas transfonteiriças.
Cutting Edge: ACVRL1 Signaling Augments CD8α+ Dendritic Cell Development
Authors: Verma Rohit , Jaiswal Hemant , Chauhan Kuldeep Singh , Kaushik Monika , Tailor Prafullakumar
Published: July 2016

Dendritic cells (DCs) are a collection of different subtypes, each of which is characterized by specific surface markers, gene-expression patterns, and distinct functions. Members of the IFN regulatory factor family play critical roles in DC development and functions. Recently, Irf8 was shown to activate TGF-β signaling, which led to exacerbated neuroinflammation in the experimental autoimmune encephalomyelitis mouse model. We analyzed the effect of Irf8 on TGF-β/bone morphogenetic protein pathway–specific genes in DCs and identified Acvrl1, a type I TGF-β superfamily receptor, as a gene strongly induced by Irf8 expression. Among various DC subtypes, Acvrl1 is differentially expressed in CD8α+ DCs. ACVRL1 signaling augmented Irf8-directed classical CD8α+ DC development. Irf8 expression is essential for plasmacytoid DC and CD8α+ DC development, and this study demonstrates that ACVRL1 signaling plays a pivotal role whereby it suppresses plasmacytoid DC development while enhancing that of CD8α+ DCs, thus contributing to DC diversity development.
Group 2 Innate Lymphoid Cells Promote an Early Antibody Response to a Respiratory Antigen in Mice

Published: July 2016

Innate lymphoid cells (ILCs) are a new family of immune cells that play important roles in innate immunity in mucosal tissues, and in the maintenance of tissue and metabolic homeostasis. Recently, group 2 ILCs (ILC2s) were found to promote the development and effector functions of Th2-type CD4+ T cells by interacting directly with T cells or by activating dendritic cells, suggesting a role for ILC2s in regulating adaptive immunity. However, our current knowledge on the role of ILCs in humoral immunity is limited. In this study, we found that ILC2s isolated from the lungs of naive BALB/c mice enhanced the proliferation of B1- as well as B2-type B cells and promoted the production of IgM, IgG1, IgA, and IgE by these cells in vitro. Soluble factors secreted by ILC2s were sufficient to enhance B cell Ig production. By using blocking Abs and ILC2s isolated from IL-5–deficient mice, we found that ILC2-derived IL-5 is critically involved in the enhanced production of IgM. Furthermore, when adoptively transferred to Il7r−/− mice, which lack ILC2s and mature T cells, lung ILC2s promoted the production of IgM Abs to a polysaccharide Ag, 4-hydroxy-3-nitrophenylacetyl Ficoll, within 7 d of airway exposure in vivo. These findings add to the growing body of literature regarding the regulatory functions of ILCs in adaptive immunity, and suggest that lung ILC2s promote B cell production of early Abs to a respiratory Ag even in the absence of T cells.

Immunosuppression is a major complication of alcoholism that contributes to increased rates of opportunistic infections and sepsis in alcoholics. The NLRP3 inflammasome, a multiprotein intracellular pattern recognition receptor complex that facilitates the cleavage and secretion of the proinflammatory cytokines IL-1β and IL-18, can be inhibited by ethanol, and we sought to better understand the mechanism through which this occurs and whether chemically similar molecules exert comparable effects. We show that ethanol can specifically inhibit activation of the NLRP3 inflammasome, resulting in attenuated IL-1β and caspase-1 cleavage and secretion, as well as diminished apoptosis-associated speck-like protein containing a CARD (ASC) speck formation, without affecting potassium efflux, in a mouse macrophage cell line (J774), mouse bone marrow–derived dendritic cells, mouse neutrophils, and human PBMCs. The inhibitory effects on the Nlrp3 inflammasome were independent of γ-aminobutyric acid A receptor activation or N-methyl-d-asparate receptor inhibition but were associated with decreased oxidant production. Ethanol treatment markedly decreased cellular tyrosine phosphorylation, whereas administration of the tyrosine phosphatase inhibitor sodium orthovanadate prior to ethanol restored tyrosine phosphorylation and IL-1β secretion subsequent to ATP stimulation. Furthermore, sodium orthovanadate–induced phosphorylation of ASC Y144, necessary and sufficient for Nlrp3 inflammasome activation, and secretion of phosphorylated ASC were inhibited by ethanol. Finally, multiple alcohol-containing organic compounds exerted inhibitory effects on the Nlrp3 inflammasome, whereas 2-methylbutane (isopentane), the analogous alkane of the potent inhibitor isoamyl alcohol (isopentanol), did not. Our results demonstrate that ethanol antagonizes the NLRP3 inflammasome at an apical event in its activation through the stimulation of protein tyrosine phosphatases, an effect shared by other short-chain alcohols.
Power Series Rings Over Prüfer v-multiplication Domains. II
Authors: Whan Chang Gyu
Published: July 2016

Let D be an integral domain, X1(D) be the set of height-one prime ideals of D, {Xβ} and {Xα} be two disjoint nonempty sets of indeterminates over D, D[{Xβ}] be the polynomial ring over D, and D[{Xβ}][[{Xα}]]1 be the first type power series ring over D[{Xβ}]. Assume that D is a Prüfer v-multiplication domain (PvMD) in which each proper integral t-ideal has only finitely many minimal prime ideals (e.g., t-SFT PvMDs, valuation domains, rings of Krull type). Among other things, we show that if X1(D) = Ø or DP is a DVR for all P ∊ X1(D), then D[{Xβ}][[{Xα}]]1D−{0} is a Krull domain. We also prove that if D is a t-SFT PvMD, then the complete integral closure of D is a Krull domain and ht(M[{Xβ}][[{Xα}]]1) = 1 for every height-one maximal t-ideal M of D.
Design and Optimization of Variable Rectangular Cross Section Chassis for On-Road Heavy Vehicles
Authors: Rajasekar K. , Saravanan R. , Dhandapani N.V.
Published: July 2016

All the loads generated by other components of heavy vehicle are transferred to its chassis. Chassis related failures are few but the damages to the safety of occupant are huge; sometimes it leads to fatal accidents. In order to overcome this, the chassis has to be optimized based on static and dynamic loads by ensuring a uniform distribution of stress and strain. The shape and cross section of the chassis gives a resistance to the above mentioned loads. The cross section of the chassis structure of all on-road vehicles is uniform despite the variable loads. In this work, variable cross section chassis of an on-road heavy vehicle is designed by keeping optimum sections. Bending moment of the chassis has been mathematically related with section modulus of the chassis. Genetic algorithm based procedures have been used to optimize the height, width and thickness of the chassis cross section. Coding in C language is used to automate the genetic algorithm procedures. For benchmark study, 3D models of optimized and existing chassis of an on-road heavy vehicle were developed. Finite element analysis reveals that the optimized chassis has less failure possibilities due to lower stress values and uniform distribution when compared to those from the model of existing chassis.
Vibration Measurement and Spectral Analysis of Chassis Frame Mounted Structure for Off-Road Wheeled Heavy Vehicles
Authors: Deulgaonkar V.R.
Published: July 2016

Chassis mounted structure is a base component for shelters or containers mounted on heavy transport vehicles. When the vehicle is driven in rough terrains or during off-road transportation this structure has a significant role in protecting the sophisticated cargo and intelligent tracking systems placed inside the shelters. During off-road transportation or warhead conditions the vehicle is subjected to large unevenness in load due to road or soil irregularities in rough terrains, which causes vibrations to be induced in the vehicle. As the nature of vibrations induced in vehicle during travel on off-road or cross-country terrains is random and unpredictable, there is a concern to analyse the vibration response of chassis and chassis mounted structures is needed. Present work deals with vibration measurement and spectral analysis of a chassis mounted structure designed for off-road and commercial transport vehicles. The road profile on which the vibration measurement has been carried out includes paved road and cross-country terrain segments. The vibration measurement has been carried at three different vehicle speeds. Signal analysis procedure for the acquired test data is discussed. The chassis mounted structure under concern is intended to hold two shelters or containers. From the vibration measurement at critical locations, g-(RMS) and g-(peak) values for paved and cross-country roads have been found out. Power spectral density values have also been found on chassis and structure for the same transport situations. Major inferences include the evaluation of minimum and maximum g-values (peak and RMS) on chassis and chassis mounted structure. Power spectral density graphs are constructed from which the dominant frequency for both road profiles is found out.

Published: July 2016

In recent years, the use of active control mechanisms in active suspension systems has attracted considerable attention. The main objective of this research is to develop a mathematical model of an active suspension system that is subjected to excitation from different road profiles and control it using Hâˆž technique for a quarter car model to improve the ride comfort and road handling. Comparison between passive and active suspension systems is performed using step, sinusoidal and random road profiles. The performance of the Hâˆž controller is compared with the passive suspension system. It is found that the car body acceleration, suspension deflection and tyre deflection using active suspension system with Hâˆž technique is better than the passive suspension system.
Modelling and Simulation of Current Fed Interleaved Isolated DC-DC Boost Converter for Fuel Cell Applications
Authors: Saha S. , Bhattacharjee A. , Devaraj E.
Published: July 2016

In this a paper, a current fed, interleaved, high gain, DC-DC converter is proposed for fuel cell applications. The converter also provides electrical isolation between the load and the source by using a transformer. The input features two current fed, full bridge inverters in parallel while the output features two full bridge diode rectifiers in series. By using this topology, the high input current is shared between the two inverters. These enables the use of lower current rating semiconductor devices, reduces switching stresses and reduces the size of magnetic components. It also results in reducing the input current ripple and the output voltage ripple.

Authors: Mohanty S.B , Ravi Eswar K.M , Elangovan D. , Arun Kumar G.
Published: July 2016

In this paper, analysis and experimentation of a fourth order boost converter has been proposed for renewable energy source applications such as solar power. The output of proposed converter is fed to motor load of 220W. The main advantages of this converter are negligible current ripples at both source and load side and higher efficiency as compared to the conventional boost converter. The energy storage elements in circuit are designed and optimized using Bacterial Foraging Optimization Algorithm (BFOA) to solve the contradictory problems of steady state and dynamic performance of the system. The up-down glitch in control to output transfer function of system is reduced with the optimized values of energy storage elements in the proposed converter. Therefore dynamic response of system is analyzed with the designed values of inductor and capacitor. Closed loop control is introduced in the proposed system using proportional integral controller to maintain the output voltage constant when there is any load disturbance in the output side and wide variations in the input voltage. Simulation and hardware results of the proposed converter with input voltage of 60V and switching frequency of 100 kHz are presented.
Inter-laminar Strength of Bonded Composite Lap Joints with Selective Stitching Through the Thickness
Authors: Hemanth R.H. , Ravi Kumar G.V.V.
Published: July 2016

In bonded composite lap joints, inter-laminar strength is critical to prevent the delamination. In this paper, the phenomenon of progressive delamination in lap joints is simulated in ABAQUS software using stress based composite failure model. It is observed that in all the joints, failure initiation is due to high inter-laminar stresses at the edges of the lap joint. Use of through the thickness stitching results in a significant improvement in inter-laminar strength in joints. These joints are further analyzed for â€œselective stitchingâ€ wherein the stitching is restricted to the failure regions. The results show that selective stitching is able to provide failure strengths close to that of fully stitched model.
Development of Continuous and Real Time Structural Health Monitoring of Aircraft Primary Structure Through Embedded Carbon Nano Fiber Sensors
Authors: Nisha M.S. , Singh Dalbir , Rajaraman A.
Published: July 2016

In this article, a new approach for structural health monitoring of aircraft primary structure has been dealt with, embedded carbon nano fiber (CNF) sensors. The multi-functional ability of non-conductive Glass Fiber Reinforced Polymers (GFRP) material is enhanced by addition of conductive CNF. An experimental investigation was carried out on bi-directional glass fiber to study the damage sensing capabilities of nano composite through embedded CNF mat-based sensor. In the study, CNF was dispersed in Poly Vinyl Alcohol (PVA) solution, and PVA-CNF sensor mat was developed by using electro-spinning process. This mat was embedded into the GFRP by using vacuum resin transfer moulding process at the design stage. CNF neither increases the weight of the composites nor affects its structural and mechanical properties. CNF sensor mat at various orientation and different wt% was embedded to the GFRP. The fabrications of specimens were done using bi-directional glass fiber with epoxy resin. Incremental tensile loading and unloading were conducted during test, and their corresponding electrical conductivity was monitored. The electrical resistance measurement of the embedded PVA-CNF mat is used to assess the structural weakness during mechanical test. Mechanical loading and the change in electrical resistance were directly correlated. Residual resistance measurements of the CNF mat were monitored during unloading condition for high stress (or strain). Accumulating damage to the composite material was calculated and correlated to the electrical resistance readings. The standard size of the coupons is 250x25x2 mm as per ASTM standard D3039.

Vehicular networks and their applications have gained great attention to the research community and vehicle industry in past few years. The applications in Vehicular Ad-hoc Networks (VANETs) are growing rapidly. The two main application classes have lately gained popularity such as secured and non secured applications. In this paper, we focus on security in VANETs using Packet Bit Key Data Function (PBKDF) Algorithm. The performance of proposed algorithm is assessed using Simulation of Urban Mobility (SUMO) coupled with V2X simulation runtime infrastructure.
Gradient Load Evaluation of Chassis Frame Mounted Specialised Structure Designed for Heavy Off-Road Vehicles
Authors: Deulgaonkar V.R.
Published: July 2016

Chassis mounted structures provide a levelled base to the transport vehicles intended for on-road and off-road driving. These structures acts as cushioning elements to sophisticated cargos like intelligent tracking systems placed in shelters closed environment. These structures need sufficient strength and rigidity to withstand the load variations arising from tire-road interactions during rough road travel. Such structures need special attention during the design phase itself in order to improve the specified payload carrying capacity with optimized dimensions. Present paper focuses on formulation of a specialized structure mounted on chassis intended to carry shelters. A scaled prototype is manufactured and tested for different grade-load combinations. This is done through experimental strain measurement and analysis of the results. The data is acquired for nine different load magnitudes and is categorised into three sets as low, moderate and high magnitudes. Interrelation between the stress/strain values acquired during each load and gradient state is developed. The structure behaviour is hypothesized through the gradient strain measurement outcomes. Major design concerns include the spacing and orientation of cross-members, load locations on the structure and the road profiles. Cross-country and rough road terrain behaviour of the structure is attempted in present work.
Characterisation of Silicon Carbide and Fly Ash in LM13 Aluminium Alloy Matrix Composites
Authors: Krishnaraj C. , Divinesh P. , Mohaideen O.M.
Published: July 2016

The modern vehicles demand more thermal and mechanical properties as the speed of the vehicles is increasing. The materials used should be able to not only withstand the high temperatures but to dissipate it at a faster rate without deformation. This paper investigates the characteristics of silicon carbide (SiC) and fly ash in LM13 aluminium alloy matrix composite prepared by stir casting. The LM13 alloy has high thermal property which makes it ideal for making engines and gears. The effect of fly ash and SiC on LM13 and its influence on increasing the surface roughness was analyzed by varying their proportion. The addition of SiC and fly ash to the matrix composite increases the hardness and tensile strength of the composite which is validated by experimental results.
Do Exports lead Economic Output in Five Asian Countries? A Cointegration and Granger Causality Analysis
Authors: Huang Jiayi , Ramirez Miguel D.
Published: July 2016

This paper examines the relationship between exports and economic output for five major Asian economies using annual data in an expanded data set and employing unit root and cointegration analysis. It employs a Vector Error Correction Model (VECM) that treats all variables in the modified production function as potentially endogenous and then determines via weak exogeneity tests whether some of the key variables can be treated as exogenous (omitted from the system). Johansen cointegration tests find a positive long-run relationship between exports and economic output for the Philippines, Singapore, and Thailand. Cointegration tests find a negative long-run relationship between exports and economic output for India. The Block Granger causality tests and impulse response functions for the Philippines and Singapore find stronger causality from exports to economic output rather than the reverse. Granger causality tests in level form also find significant causality from exports to economic output. No causality exists between exports and economic output in the case of India. Exports seem to promote economic growth in three of the four countries that have cointegrated data, which supports the exports-led growth hypothesis found in some of the extant literature. The paper does not find cointegration for China because the variables are integrated of different orders from I(0) to I(2).
Congenital agenesis of inferior vena cava as a rare cause of deep vein thrombosis: Case report and review of the literature
Authors: Ackula Haritha , Mosalpuria Kailash , Tandra Pavankumar
Published: July 2016

Inferior vena cava agenesis (IVCA) is an uncommon cause of deep vein thrombosis (DVT). We report the case of a 26-year-old Caucasian female with unilateral iliofemoral DVT. On further evaluation, CT abdomen revealed diminutive inferior vena cava consistent with IVCA. We have used systemic anticoagulation and catheter mediated thrombolysis with success in this case. Physicians should suspect IVCA in patients with extensive DVT especially in younger individuals.
Hip Vascularity: A Review of the Anatomy and Clinical Implications
Authors: Seeley Mark Alan , Georgiadis Andrew G. , Sankar Wudbhav N.
Published: July 2016

Throughout development, the vascular supply to the proximal femur and acetabulum undergoes a series of changes during which it is susceptible to injury. Before age 3 months, the ligamentum teres and lateral epiphyseal arteries are the dominant supply to the developing head. The dominant supply shifts to the lateral epiphyseal vessels by age 18 months. The distinct metaphyseal and epiphyseal circulations of the adult proximal femur form in adolescence when an increasingly rich metaphyseal circulation supplies the subphyseal region, terminating at the physeal plate. The acetabular blood supply derives from two independent systems, with the dominance of each changing throughout maturity. Most descriptions of the vascular contributions to the proximal femur and acetabulum have been gross anatomic and histologic studies. Advanced imaging studies (eg, CT angiography, perfusion MRI) have added to our understanding of the vascular anatomy of the proximal femur and acetabulum, its changes throughout development, and its clinical implications.
A semiótica visual e a análise do discurso a partir de uma imagem sincrética em Pina (2011) de Wim Wenders

Authors: Silva Marcela Guimarães , Martins Tiago Costa
Published: July 2016

A partir de um exercício metodológico de tipo-ideal este artigo tem por objetivo compreender a dinâmica das múltiplas realidades que envolvem o mundo social, especialmente o mundo dos gaúchos campeiros oriundos do interior do Rio Grande do Sul, Brasil. A compreensão da fenomenologia social, através do ensaio de Alfred Schutz sobre a obra de Miguel de Cervantes, Dom Quixote, é a base comparativa para entender como o contexto social, as interações em co-presença e as interações mediadas são elementos que compõe o processo de construção da realidade. O estudo empírico realizado com os gaúchos do meio rural, especialistas nas atividades pastoris, destaca uma realidade particular e positiva para o entendimento do território, do desenvolvimento e da condição de vida. Os resultados sob o ponto de vista fenomenológico são pertinentes ao se analisar o contexto social e as interações estabelecidas no “âmbito de significado finito” na vida desses agentes sociais.
