Just in Time Purchasing an Approach in Supply Chain Management and Its Relevance to Indian Automotive Industry
Authors: Raju T V , Gopal R K 
Published: June 2019

In today's highly competitive global market place the pressure on organizations to find new ways to create and deliver value to the customers grows ever stronger. There have been many new ideas and concepts in business management over the last thirty or so years, some of which have endured and others discarded. However, perhaps one of the most significant principles to become widely adopted and practiced is that of just in time, or JIT. It is a philosophy as much, as it is a technique; it is based upon the simple idea that wherever possible no activity should take place in the system until there is a need for it.
With increasing pressures on profits, due to the launch of several new models, with marginal differences in prices, Indian Automotive companies would do well to move towards JIT purchasing systems. Given the extent and variety of constraints and the existing purchasing mindset in Indian Automotive industry, it'will take some more time to understand and practice the technique.
This paper attempts to understand the possibilities of implementing JIT technique in the Indian automotive industry. This will help the automotive component manufacturers to effectively formulate their marketing strategies to create value to their OEM customers. It also helps the vehicle manufacturers to be competitive in the end market.
The Optimality of Ad Valorem Contracts
Authors: Hagiu Andrei , Wright Julian 
Published: June 2019

We provide a new theory of ad valorem contracts (i.e., contracts that vary with the value of the transaction), which can explain why such contracts are widely used between vertically related parties (e.g., in franchising and licensing). Ad valorem contracts allow upstream firms (principals) to preserve their own incentives to make ongoing investments in the channel and deal with pricing distortions caused by channel coordination problems, while at the same time adjusting their investment on the basis of demand shocks that are only observed by the downstream firms (agents). We show that the optimal ad valorem contract allows the principal to achieve the same profits as if it could observe the demand shocks and control price. This optimal contract makes use of revenue sharing (to balance investment incentives and make the principal’s investment responsive to demand through price), upfront fixed fees (to extract the agents’ expected profit), and an additional term that depends nonlinearly on either price or demand (to correct for remaining pricing distortions). Our results are robust to the introduction of competition between agents, production costs, and imperfect monitoring of the agents’ prices. This paper was accepted by Eric Anderson, marketing.
La utilidad de la ficción en la poesía
Authors: Palma Castro Alejandro 
Published: June 2019

En este artículo realizo un recorrido por la poesía desde la Edad Media hasta la época contemporánea revisando casos singulares donde se manifiesta la ficción. A partir de una lectura pragmática de estos poemas, en específico la enunciación, demuestro cómo la ficción más que una característica del lenguaje literario ha sido un medio que nos ha permitido interpretar y hasta crear la realidad desde nuevas experiencias. En la poesía trovadoresca, por ejemplo, es destacable cómo su ficción permitió la creación de saberes culturales que subsisten y han determinado nuestra época. También en la Edad Media, una cantiga del rey de Portugal, Don Dinis, pone en perspectiva el desarrollo cultural y económico de su reino. Posteriormente destaco al enunciador del célebre Primero sueño de Sor Juana Inés de la Cruz como experiencia posible de un sujeto femenino no contemplado en los cerrados esquemas sociales del virreinato. Concluyo el recorrido con un análisis sobre la evanescencia del sujeto poético en la poesía de Leopoldo María Panero como posibilidad para encarar el temor a la muerte. Este recorrido argumental me permite concluir que la poesía ha hecho uso de la ficción de una manera distinta a otros géneros literarios pero poco hemos reflexionado y caracterizado su procedimiento.

Reconstruction of Tesla micro-valve using topological sensitivity analysis
Authors: Abdelwahed M. , Chorfi N. , Malek R. 
Published: June 2019

Abstract
In this paper, we deal with topology optimization attributed to the non stationary Navier-Stokes equations. We propose an approach where we analyze the sensitivity of a shape function relating to a perturbation of the flow domain. A numerical optimization algorithm based on topological gradient method is built and applied to the 2D Tesla micro valve reconstruction. Some numerical results confirm the efficiency of the proposed approach.
Morphology and Dynamics of the Baltic Sea Shore within Kaliningrad Oblast (Overview)
Authors: Babakov Aleksandr 
Published: June 2019

Abstract
A review of morphological and morphodynamic studies of the coast of the Kaliningrad oblast has been carried out for half a century. The studies include monitoring measurements by the Atlantic Branch of the Shirshov Institute of Oceanology of the Russian Academy of Sciences (AB IO RAS) with the participation of the state institute Baltberegozashchita (BBZ), as well as pre-war studies and cartographic analyses of long-term coastline migration carried out by the private company Baltic Aerogeodetic Enterprise (BaltAGE). It shows the spatial alternation of abrasive and accumulative areas, as well as frequent changes in beach width and height within the same morphological coast type. A change in the development trend of particular coast sections from year to year was noted. The significant influence of anthropogenic factors on the coastal development was emphasized, including changes in the direction of coastal retreat/advance along an extensive coastal stretch. Comparison of the interannual and nearly century-old dynamics of the coast revealed noticeable differences between them, with opposite trends in several large-scale coast sections.
Simulation of Sea-ice Thermodynamics by a Smoothed Particle Hydrodynamics Method
Authors: Staroszczyk Ryszard 
Published: June 2019

Abstract
The paper deals with the problem of sea-ice pack motion and deformation under the action of wind and water drag forces. Differential equations describing the behaviour of ice, with its very distinct material responses in converging and diverging flows, express the mass and linear momentum balances on a horizontal plane (the free surface of the ocean). The thermodynamic effects (ice melting and lead water freezing) are accounted for by adding source terms to the equations describing the evolution of the ice thickness and area fraction (concentration). These thermodynamic source terms are described by means of a single function that idealizes typical ice growth-rates observed in winter in the Arctic. The equations governing the problem are solved by a fully Lagrangian method of the smoothed particle hydrodynamics (SPH). Assuming that the ice behaviour can be approximated by a non-linearly viscous rheology, the proposed SPH model was used to simulate the flow of a sea-ice pack driven by wind drag stresses and varying seasonal temperatures. The results of numerical simulations illustrate the evolution of an ice pack, including distributions of ice thickness and ice area fraction in space and time for assumed temperature distributions.

Published: June 2019

Abstract
This elementary work aims to address agglomeration and non-uniform dispersion of reinforcement particles in stir casting using Al6061 alloy (AA 6061) as a matrix and Aluminium oxide (Al2O3) as reinforcement particles. A novel combined feeding method of Encapsulate feeding technique & Two Step Stir Casting was developed & attempted to produce good quality composites by varying weight fractions of Aluminium Oxide (0 to 5 wt.%). The wetting agent Mg (2 wt.%) added in all castings to ensure better binding between ceramics and matrix. The SEM photomicrograph ensures homogenous dispersion of reinforcement particles by combined feeding method. The thermal properties of produced good quality composites are enhanced with increase in Aluminium Oxide (Al2O3) from 0 to 5 wt.%.
Revisiting the Euro’s Trade Cost and Welfare Effects
Authors: Felbermayr Gabriel , Steininger Marina 
Published: June 2019

AbstractWhen, about twenty years ago, the Euro was created, one objective was to facilitate intra-European trade by reducing transaction costs. Has the Euro delivered? Using sectoral trade data from 1995 to 2014 and applying structural gravity modeling, we conduct anex postevaluation of the European Monetary Union (EMU). In aggregate data, we find a significant average trade effect for goods of almost 8 percent, but a much smaller effect for services trade. Digging deeper, we detect substantial heterogeneity between sectors, as well as between and within country-pairs. Singling out Germany, and embedding the estimation results into a quantitative general equilibrium model of world trade, we find that EMU has increased real incomes in all EMU countries, albeit at different rates. E. g. incomes have increased by 0.3, 0.6, and 2.1 percent in Italy, Germany, and Luxembourg, respectively.

Optimization of Hot Workability of Cu-Cr-Zr-Ti Alloy Through Development of a Processing Map
Authors: Sarkar Aditya , Narayana Murty S. V. S. , Prasad M. J. N. V. 
Published: June 2019

Abstract
Owing to high thermal conductivity, copper-based alloys are used to fabricate heat transfer elements of rocket engines, such as combustion chambers, nozzle liners, and metal gaskets. One such alloy is the Copper-Chromium-Zirconium-Titanium (Cu-Cr-Zr-Ti) alloy, which possesses a good combination of thermal conductivity and strength at high temperatures. Thermomechanical processing is an important step in the realization of the various aforementioned heat transfer elements from this alloy. Hence, it is imperative to understand the hot deformation behavior of the alloy as a function of the process variables such as temperature and strain rate. An attempt is made to study the hot deformation behavior of the Cu-Cr-Zr-Ti alloy by subjecting it to uniaxial hot compression tests in the temperature range of 600°C–800°C and strain rate range of 0.001–10 s−1. The flow stress measurement tests were conducted up to a true strain of 0.5 using a Gleeble 3800 simulator. The nature of the flow curves obtained at the completion of the tests indicated the occurrence of dynamic recrystallization (DRX) at deformation temperatures greater than 700°C and with a strain rate below 1 s−1. The work hardening rate was plotted as a function of effective flow stress to assess the flow softening behavior due to DRX at different deformation conditions. A processing map delineating the stable and unstable regions during hot working is developed and validated by observing the microstructures in the corresponding domains. Optimum processing parameters (temperature of 750°C and strain rate of 0.1–10 s−1) for hot working of the alloy were proposed based on a contour map of efficiency of power dissipation. Two constitutive equations are also established: one using the Hyperbolic sine law as proposed by Sellars and McTegart and the other using Kocks Mecking analysis.
3D Electron Microscopy Study of Synaptic Organization of the Normal Human Transentorhinal Cortex and Its Possible Alterations in Alzheimer’s Disease
Authors: Domínguez-Álvaro M. , Montero-Crespo M. , Blazquez-Llorca L. , DeFelipe J. , Alonso-Nanclares L. 
Published: June 2019

AbstractThe transentorhinal cortex (TEC) is an obliquely oriented cortex located in the medial temporal lobe and, together with the entorhinal cortex, is one of the first affected areas in Alzheimer’s disease (AD). One of the most widely accepted hypotheses is that synaptopathy (synaptic alterations and loss) represents the major structural correlate of the cognitive decline observed in AD. However, very few electron microscope (EM) studies are available; the most common method to estimate synaptic density indirectly is by counting, at the light microscopic level, immunoreactive puncta using synaptic markers. To investigate synaptic morphology and possible alterations related to AD, a detailed three-dimensional (3D) ultrastructural analysis using focused ion beam/scanning EM (FIB/SEM) was performed in the neuropil of Layer II of the TEC in human brain samples from non-demented subjects and AD patients. Evaluation of the proportion and shape of asymmetric synapses (AS) and symmetric synapses (SS) targeting spines or dendritic shafts was performed using 3D reconstructions of every synapse. The 3D analysis of 4722 synapses revealed that the preferable targets were spine heads for AS and dendritic shafts for SS, both in control and AD cases. However, in AD patients, we observed a reduction in the percentage of synapses targeting spine heads. Regarding the shape of synapses, in both control cases and AD samples, the vast majority of synapses had a macular shape, followed by perforated or horseshoe-shaped synapses, with fragmented synapses being the least frequent type. Moreover, comparisons showed an increased number of fragmented AS in AD patients.
Vasopressin Cells in the Rodent Olfactory Bulb Resemble Non-Bursting Superficial Tufted Cells and Are Primarily Inhibited upon Olfactory Nerve Stimulation
Authors: Lukas Michael , Suyama Hajime , Egger Veronica 
Published: June 2019

AbstractThe intrinsic vasopressin system of the olfactory bulb is involved in social odor processing and consists of glutamatergic vasopressin cells (VPCs) located at the medial border of the glomerular layer. To characterize VPCs in detail, we combined various electrophysiological, neuroanatomical, and two-photon Ca2+imaging techniques in acute bulb slices from juvenile transgenic rats with eGFP-labeled VPCs. VPCs showed regular non-bursting firing patterns, and displayed slower membrane time constants and higher input resistances versus other glutamatergic tufted cell types. VPC axons spread deeply into the external plexiform and superficial granule cell layer (GCL). Axonal projections fell into two subclasses, with either denser local columnar collaterals or longer-ranging single projections running laterally within the internal plexiform layer and deeper within the granule cell layer. VPCs always featured lateral dendrites and a tortuous apical dendrite that innervated a single glomerulus with a homogenously branching tuft. These tufts lacked Ca2+transients in response to single somatically-evoked action potentials and showed a moderate Ca2+increase upon prolonged action potential trains.Notably, electrical olfactory nerve stimulation did not result in synaptic excitation of VPCs, but triggered substantial GABAAreceptor-mediated IPSPs that masked excitatory barrages with yet longer latency. Exogenous vasopressin application reduced those IPSPs, as well as olfactory nerve-evoked EPSPs recorded from external tufted cells. In summary, VPCs can be classified as non-bursting, vertical superficial tufted cells. Moreover, our findings imply that sensory input alone cannot trigger excitation of VPCs, arguing for specific additional pathways for excitation or disinhibition in social contexts.
Oncogenic Pathways and Loss of the Rab11 GTPase Synergize To Alter Metabolism in Drosophila

Published: June 2019

Abstract
Colorectal cancer is a complex disease driven by well-established mutations such as APC and other yet to be identified pathways. The GTPase Rab11 regulates endosomal protein trafficking, and previously we showed that loss of Rab11 caused intestinal inflammation and hyperplasia in mice and flies. To test the idea that loss of Rab11 may promote cancer progression, we have analyzed archival human patient tissues and observed that 51 out of 70 colon cancer tissues had lower Rab11 protein staining. By using the Drosophila midgut model, we have found that loss of Rab11 can lead to three changes that may relate to cancer progression. First is the disruption of enterocyte polarity based on staining of the FERM domain protein Coracle. Second is an increased proliferation due to an increased expression of the JAK-STAT pathway ligand Upd3. Third is an increased expression of ImpL2, which is an IGFBP7 homolog and can suppress metabolism. Furthermore, loss of Rab11 can act synergistically with the oncoprotein RasV12 to regulate these cancer-related phenotypes.
