Fluid-Structural Interaction in a Slip Joint of a Jet Pump Assembly of a BWR-5
Authors: Castro Juan Cruz , López Grijalba Yunuén , Gómez Luis Héctor Hernández , Sánchez Israel Abraham Alarcón , López Pablo Ruiz , Fernández Juan Alfonso Beltrán
Published: February 2020

Flow-induced vibrations occur in some of the internal components of a nuclear reactor. When specific conditions are present, these vibrations may result in excessive deformations or fatigue that can generate mechanical damage. Several boiling water reactor (BWR) of nuclear power plants (NPP) have experienced failures in the jet pump assembly due to flow-induced vibration (FIV) which could be caused by acoustic pulsations derived from recirculation pumps, vibration induced by turbulence and vibration induced by leakage at the slip joint. The purpose of this paper is to establish a viable numerical methodology to evaluate the fluid-structural interaction at the slip joint of a jet pump. In this analysis, the fluid-structural interaction was evaluated with the finite element method and finite volume method with ANSYS® code in the case of two steel plates with a divergent gap. Results show that a critical velocity could cause fluidelastic instability, if only one flow in a two-way fluid-structural interaction was considered. This is one of the phenomena that could take place at the slip joint of a jet pump assembly.

Authors: Koštial Pavol , Vlček Jozef , Koštialová Jančíková Zora , Ružiak Ivan , Gajtanska Milada , Velička Marek , Bošák Ondrej , Špačková Hana
Published: February 2020

The paper is devoted to the study of thermal parameters (specific heat capacity, diffusivity and thermal conductivity) changes after thermally induced aging of BMC Mensolite 3100. Results of several measurements are statistically treated. From obtained results it is visible the greatest correlation in the diffusivity values, i.e. the heat irradiation effect is the smallest on the diffusivity values dispersion, the influence of the heat irradiation on the thermal capacity has approximately the same trend as the thermal conductivity. From the starting point represented by the virgin sample both values decrease and for the sample heated at 300°C it is visible an increase of the above mentioned values under investigation. Results are interpreted by using of the thermogravimetric analysis (TGA). All physical values under this investigation have a dominant decreasing tendency after the thermal treatment described.

Published: February 2020

The present work has the objective to study the water diffusion in the process of intermittent solar drying of mangabas. Osmotic dehydration (OD) pretreatment was performed in sucrose solution and the drying took place in a direct solar dryer with the fruits arranged in stainless steel screens, temperatures varying between 30 and 45°C along the day with peaks of 70°C. The period of intermittence was approximately 16 h reaching equilibrium after 6 days. The diffusional model based on the second Fick’s law was proposed for each of the daily drying periods of 360 minutes, considered that the process is controlled by internal diffusion, negligible external resistance, spherical geometry, shrinkage based on the average radius. The coefficients of effective diffusion (Def) obtained by using 4 terms of the infinite series, present values of Def ranging from 0.2 to 3.30x10-10 m2/s with R2≥ 0.868 and average relative deviations MRD≤10-2.
Mathematical Solution on MHD Stagnation Point Flow of Ferrofluid
Authors: Yasin Siti Hanani Mat , Mohamed Muhammad Khairul Anuar , Ismail Zulkhibri , Salleh Mohd Zuki
Published: February 2020

This study presents a numerical investigation on the magnetohydrodynamic (MHD) stagnation point flow of a ferrofluid with Newtonian heating. The black oxide of iron, magnetite (Fe3O4) which acts as magnetic materials and water as a base fluid are considered. The two dimensional stagnation point flow of cold ferrofluid against a hot wall under the influence of the uniform magnetic field of strength is located some distance behind the stagnation point. The effect of magnetic and volume fraction on the velocity and temperature boundary layer profiles are obtained through the formulated governing equations. The governing equations which are in the form of dimensional non-linear partial differential equations are reduced to dimensionless non-linear ordinary differential equations by using appropriate similarity transformation. Then, they are solved numerically by using the Keller-box method which is programmed in the Matlab software. It is found that the cold fluid moves towards the magnetic source that is close to the hot wall. Hence, leads to the better cooling rate and enhances the heat transfer rate. Meanwhile, an increase of the magnetite nanoparticles volume fraction, increases the ferrofluid capabilities in thermal conductivity and consequently enhances the heat transfer.
Hydro-Elastic Oscillations of the Bottom Membrane of a Rectangular Container Filled with Fluid
Authors: Gascón-Pérez Manuel
Published: February 2020

The analysis of the hydro-elastic interactions of the covering membrane of fluid-filled cavities or containers has a main importance due to the solution of practical problems founded in engineering applications. In this paper the dynamic behaviour of the bottom membrane of a rectangular container filled with a non-viscous and incompressible fluid is analyzed. The fluid velocity potential is obtained first by applying a method of separation of variables and afterwards the pressure field is calculated with the momentum’s linearized equation. Taking into account the deformation equation for the membrane in contact with the fluid and by applying a discretization procedure to the associated generalized work equation, a system is obtained, for the calculus of the membrane frequencies of vibration. The influence of different geometrical parameters such as dimension, aspect ratio, container relative height, relative thickness as well as the fluid density on these frequencies is analysed. Validation of the method is made by comparing the results with those obtained by other authors and theories.
Slippage Effect on the Oscillatory Electroosmotic Flow of Power-Law Fluids in a Microchannel
Authors: Baños Ruben , Arcos José , Bautista Oscar , Méndez Federico
Published: February 2020

The oscillatory electroosmotic flow (OEOF) under the influence of the Navier slip condition in power law fluids through a microchannel is studied numerically. A time-dependent external electric field (AC) is suddenly imposed at the ends of the microchannel which induces the fluid motion. The continuity and momentum equations in the and direction for the flow field were simplified in the limit of the lubrication approximation theory (LAT), and then solved using a numerical scheme. The solution of the electric potential is based on the Debye-Hückel approximation which suggest that the surface potential is small, say, smaller than 0:025V and for a symmetric () electrolyte. Our results suggest that the velocity profiles across the channel-width are controlled by the following dimensionless parameters: the dimensionless slip length , the Womersley number, , the electrokinetic parameter, , defined as the ratio of the characteristic length scale to the Debye length, the parameter which represents the ratio of the Helmholtz-Smoluchowski velocity to the characteristic length scale and the flow behavior index, . Also, the results reveal that the velocity magnitude gets higher values as increases and become more and more nonuniform across the channel-width as the and are increased, so OEOF can be useful in micro-fluidic devices such as micro-mixers.
Universal Alternating Semiregular Polytopes
Authors: Monson B. , Schulte Egon
Published: February 2020

In the classical setting, a convex polytope is said to be semiregular if its facets are regular and its symmetry group is transitive on vertices. This paper continues our study of alternating semiregular abstract polytopes, which have abstract regular facets, still with combinatorial automorphism group transitive on vertices and with two kinds of regular facets occurring in an alternating fashion.

Our main concern here is the universal polytope ${\mathcal{U}}_{{\mathcal{P}},{\mathcal{Q}}}$, an alternating semiregular $(n+1)$-polytope defined for any pair of regular $n$-polytopes ${\mathcal{P}},{\mathcal{Q}}$ with isomorphic facets. After a careful look at the local structure of these objects, we develop the combinatorial machinery needed to explain how ${\mathcal{U}}_{{\mathcal{P}},{\mathcal{Q}}}$ can be constructed by “freely assembling” unlimited copies of ${\mathcal{P}}$, ${\mathcal{Q}}$ along their facets in alternating fashion. We then examine the connection group of ${\mathcal{U}}_{{\mathcal{P}},{\mathcal{Q}}}$, and from that prove that ${\mathcal{U}}_{{\mathcal{P}},{\mathcal{Q}}}$ covers any $(n+1)$-polytope ${\mathcal{B}}$ whose facets alternate in any way between various quotients of ${\mathcal{P}}$ or ${\mathcal{Q}}$.
Regularity estimates in weighted Morrey spaces for quasilinear elliptic equations
Authors: Di Fazio Giuseppe , Nguyen Truyen
Published: February 2020

We study regularity for solutions of quasilinear elliptic equations of the form

\mathrm {div}\mathbf{A}(x,u,\nabla u)=\mathrm {div}\mathbf{F}

in bounded domains in

\mathbb{R}^n

. The vector field

\mathbf{A}

is assumed to be continuous in

u

, and its growth in

\nabla u

is like that of the

p

-Laplace operator. We establish interior gradient estimates in weighted Morrey spaces for weak solutions

u

to the equation under a small BMO condition in

x

for

\mathbf{A}

. As a consequence, we obtain that

\nabla u

is in the classical Morrey space

\mathcal{M}^{q,\lambda}

or weighted space

L^q_w

whenever

|\mathbf{F}|^{1/(p-1)}

is respectively in

\mathcal{M}^{q,\lambda}

or

L^q_w

, where

q

is any number greater than

p

and

w

is any weight in the Muckenhoupt class

A_{q/p}

. In addition, our two-weight estimate allows the possibility to acquire the regularity for

\nabla u

in a weighted Morrey space that is different from the functional space that the data

|\mathbf{F}|^{1/(p-1)}

belongs to.

Endogenous money in an era of financialization
Authors: Sawyer Malcolm
Published: February 2020

The paper opens with a consideration of the historical developments on the nature and features of money and endogenous money, and the post-Keynesian revival of ideas of endogenous money. Particular attention is drawn to the work of Basil Moore in relation to endogenous money, including the location of that analysis with commercial banks (some of whose liabilities are transferable and widely accepted as a means of payment) and the post-Keynesian-inspired revival of endogenous money. There is a brief outline of the aspects of financialization since the late 1970s which have relevance for the analysis of banks and money. Some thoughts are offered on the impact which those changes of the financial system have for the analysis of banks and of money.

Symphonya. Emerging Issues in Management launches a new editorial line called 'Special Issue on' aimed at promoting Symphonya's specific vocation to maintaining a close link between the academic world and the business world through in-depth analyses of 'emerging issues' that managers are facing in global markets. This Special Issue is dedicated to the theme of the creation of new businesses. In today's competitive environment characterised by globalised markets, oversupply and a trend towards concentration in most sectors, innovation is a requisite factor for the survival of enterprises and the territories in which they operate. The Italian Start-up Act, introduced in late 2012 and incrementally enriched in subsequent years, is indeed a remarkable policy in a comparative context. Italian start-ups have been endowed with real, diverse and potentially high-impact instruments to find their own way to market and to success.
Entrepreneurship, Local Growth and Global Markets
Authors: Cappiello Giuseppe
Published: February 2020

The creation or start-up of new companies has been the subject of extensive discussion in recent years, both at a scientific and a political level.  The reason for this lies primarily in the hope that new businesses will contribute to local development and employment. The birth of new businesses concerns three dimensions: the subjective one, the context in which the company was founded and the strategic choices made. These choices are particularly useful in understanding that an organic, all-encompassing design is required, especially if a global ecosystem is involved.  At the same time, it seems necessary for the State to play an enabling role.

The introduction of an innovative organization like Digital Borgo in a strongly conservative context, made mostly by SMEs and few big companies, often with no relationships to each other modify their interests in collaborating and exchanging knowledge. Overcoming all limits, hurdles and an unfavorable mindset, we managed to define a corporate accelerator model that can represent a virtuous example, helping corporates, entrepreneurs, chambers of commerce and universities to collaborate to foster innovation. We are confident that in the future we will be able to say that our model has created a more connected ecosystem among entrepreneurs and innovating corporates, making Abruzzo a region where small cities and low cost of life becomes an advantage for setting up a great ecosystem for innovation and smart growth.

Despite a challenging external environment, four successive PLL arrangements
since 2012 have supported reforms to strengthen macroeconomic resilience, economic
growth and inclusion. Yet, economic growth, below 3 percent, is not robust enough and
unemployment remains high, especially among the youth and women. Growth is also
subject to elevated risks, including weak economic growth in the euro area, and
geopolitical risks. In this environment, Morocco needs to step up reforms to further
enhance its macroeconomic resilience, build buffers, and move towards more private
sector-led, inclusive and job-rich growth. Priority areas include: taxation; public
governance and the fight against corruption; social spending to reduce inequalities;
labor market and education reforms; and greater exchange rate flexibility.

Coronary computed tomography angiography using model-based iterative reconstruction algorithms in the detection of significant coronary stenosis: how the plaque type influences the diagnostic performance
Authors: Vizzuso Antonio , Righi Riccardo , Carnevale Aldo , Zerbini Michela , Benea Giorgio , Giganti Melchiore
Published: February 2020

Purpose

To evaluate the ability of coronary computed tomography angiography (CCTA) with model-based iterative reconstruction (MBIR) algorithm in detecting significant coronary artery stenosis compared with invasive coronary angiography (ICA).

Material and methods

We retrospectively identified 55 patients who underwent CCTA using the MBIR algorithm with evidence of at least one significant stenosis (≥ 50%) and an ICA within three months. Patients were stratified based on calcium score; stenoses were classified by type and by coronary segment involved. Dose-length-product was compared with the literature data obtained with previous reconstruction algorithms. Coronary artery stenosis was estimated on ICAs based on a qualitative method.

Results

CCTA data were confirmed by ICA in 89% of subjects, and in 73% and 94% of patients with CS < 400 and ≥ 400, respectively. ICA confirmed 81% of calcific stenoses, 91% of mixed, and 67% of soft plaques. Both the dose exposure of patients with prospective acquisition (34) and the exposure of the whole population were significantly lower than the standard of reference (p < 0.001 and p = 0.007).

Conclusions

CCTA with MBIR is valuable in detecting significant coronary artery stenosis with a solid reduction of radiation dose. Diagnostic performance was influenced by plaque composition, being lower compared with ICA for patients with lower CAC score and soft plaques; the visualisation of an intraluminal hypodensity could cause false positives, particularly in D1 and MO segments.
Painful clicking jaw: a pictorial review of internal derangement of the temporomandibular joint
Authors: Mehndiratta Anurag , Kumar Jyoti , Manchanda Alpana , Singh Ishwar , Mohanty Sujata , Seth Novee , Gautam Richa
Published: February 2020

Temporomandibular joint disorders are a common cause of chronic musculoskeletal pain worldwide. Among these, internal disc derangement is the most frequent type of disorder. Internal derangement is defined as an abnormal positional and functional relationship between the disc and articulating surfaces. Common clinical symptoms include pain and clicking.

Imaging plays a key role in diagnosing temporomandibular joint disorders. It is important for the radiologist to detect early imaging signs of internal derangement, thereby avoiding the evolution of this condition to degenerative joint disease. The aim of this article is to familiarise the reader with the spectrum of imaging findings that are encountered at different stages of the disease.

Chinese Poetry and Translation: Rights and Wrongs offers fifteen essays on the triptych of poetry + translation + Chinese. The collection has three parts: "The Translator's Take," "Theoretics," and "Impact." The conversation stretches from queer-feminist engagement with China's newest poetry to philosophical and philological reflections on its oldest, and from Tang- and Song-dynasty classical poetry in Western languages to Baudelaire and Celan in Chinese. Translation is taken as an interlingual and intercultural act, and the essays foreground theoretical expositions and the practice of translation in equal but not opposite measure. Poetry has a transforming yet ever-acute relevance in Chinese culture, and this makes it a good entry point for studying Chinese-foreign encounters. Pushing past oppositions that still too often restrict discussions of translation-form versus content, elegance versus accuracy, and "the original" versus "the translated" - this volume brings a wealth of new thinking to the interrelationships between poetry, translation, and China.
Development on Loan
Authors: Loubere Nicholas
Published: February 2020

Key to China's plans to promote rural development is the de-marginalisation of the countryside through the incorporation of rural areas into the urban-based market-oriented financial system. For this reason, Chinese development planners have turned to microcredit -- i.e. the provision of small-scale loans to 'financially excluded' rural households -- as a means of increasing 'financial consciousness' and facilitating rural de-marginalisation. Drawing on in-depth fieldwork in rural China, this book examines the formulation, implementation and outcomes of government-run microcredit programmes in China-illuminating the diverse roles that microcredit plays in local processes of socioeconomic development and the livelihoods of local actors. It details how microcredit facilitates de-marginalisation for some, while simultaneously exacerbating the marginalisation of others; and exposes the ways in which microcredit and other top-down development strategies reflect and reinforce the contradictions and paradoxes implicit in rural China's contemporary development landscape.
Can the CCPA Access Right Be Saved? Realigning Incentives in Access Request Verification
Authors: Iafrati Rebecca
Published: February 2020

The California Consumer Privacy Act access right has the potential to give Californians a level of control over their personal information that is unprecedented in the United States. However, consumer privacy interests will be in peril unless the access right is accompanied by an effective access request verification requirement. Requiring companies to respond to access requests when they cannot verify that the requestor is the subject of the requested data puts sensitive personal information at risk. Inversely, allowing companies to shirk their access request responsibilities by claiming that data is unverifiable diminishes consumers’ data control rights. Thus, in the context of access request verification policy, there is an inherent tension between privacy as confidentiality and privacy as control. The success of the access right, and thus all CCPA data control rights, hinges on an access request verification policy that successfully balances these competing privacy interests. The endemic identity theft caused by credit application verification systems demonstrates why such balancing cannot be wholly left to private companies. In the credit context, balancing has been driven by the profit maximization interests of businesses, which currently do not align with consumer privacy interests. Fortunately, several scholars have proposed methods for aligning these divergent interests. The strengths and weaknesses from these proposed solutions to identity theft provide a useful framework for building a system that incentivizes companies to prioritize consumer privacy when developing access request verification systems.
Imagens técnicas e o pensamento imagético em Vilém Flusser: diálogos para uma epistemologia da imaginação
Authors: Ribeiro Daniel Melo
Published: February 2020

Este artigo propõe uma reflexão sobre as imagens técnicas em Vilém Flusser. Considerando a atual proliferação de superfícies e aparatos de reprodução de imagens, Flusser levanta a necessidade de desenvolvermos uma faculdade cognitiva capaz de decifrar como operam as imagens técnicas. Essa faculdade, denominada tecnoimaginação, estimularia o pensamento crítico sobre as imagens. Para elaborar esse argumento, recuperamos dois temas centrais em sua obra: a escalada da abstração e as caixas pretas. A partir desse fundamento, sugerimos que o incentivo ao pensamento imagético passa não somente pelo debate sobre a arte contemporânea, mas pelo diálogo com outros pensadores que também refletiram sobre a epistemologia da imaginação.

The Bunder Diamond Project, India: Discovery of the Saptarshi Lamproite Pipes
Authors: Krishna C. , Pande Leena , Norris R. , Howell D. , Burgess J.
Published: February 2020

The Bunder diamond project comprises a cluster of diamondiferous volcanic pipes and dikes intruding Paleoproterozoic and Mesoproterozoic intracratonic sedimentary rocks covering the Archean Bundelkhand craton, underlain by depleted peridotitic mantle lithosphere. The discovery resulted from an 18-month regional exploration program targeting potentially well preserved diamond orebodies within Neoproterozoic to Paleoproterozoic intracratonic sedimentary rocks along strike from the Majhgawan diamond mine, or possibly more eroded bodies within the exposed Bundelkhand craton to the north. High-chromium magnesiochromites and, in particular, rare G9/G10 garnets from stream sediment samples proved to be effective regional diamond indicator minerals in terms of their dispersion, recovery, and analysis. Follow-up stream sediment surveys for indicator minerals, ground magnetic surveys, and soil geochemical surveys plus visual outcrop prospecting proved to be fit for the purpose and successful in locating diamondiferous source rocks. Key factors for the Bunder discovery were the funding and creation of a dedicated team with a strong commodity focus that was able to secure exploration licenses ahead of the competition, negotiate local exploration access, and then apply local knowledge to tried-and-true exploration and sampling techniques. The ability to prioritize, process, observe, and analyze stream sediment indicator mineral samples in a timely manner at in-house laboratories was crucial.
A Study of Garnet and Chromian Spinel Xenocrysts from the Atri South Ultramafic Intrusion, Bundelkhand Craton, India
Authors: Kobussen A. F. , Howell D. , Shu Q. , Smith C. B.
Published: February 2020

The Bundelkhand craton is one of five Archean cratons that make up the Indian shield, four of which have yielded diamond discoveries. The Bunder diamond project consists of seven ultramafic intrusions, with the Mesoproterozoic Atri pipe being the largest and most prospective in terms of its diamond content. Despite the Majhgawan diamond mine also being located on the Bundelkhand craton, little information exists regarding the section of subcontinental lithospheric mantle that these deep-seated intrusions have sampled. This paper reports major and trace element data for xenocrystic chromian spinels and garnets, allowing some new interpretations of the mantle section and geotherm to be made. All of the xenocrysts recovered are of peridotitic paragenesis, with no evidence of eclogitic material being observed in concentrate.

Calculated equilibration temperatures for garnet and chromian spinel indicate sampling at a range of depths. The chromian spinel can be divided into three groups based on major and minor element characteristics, with each group being derived from different horizons within the subcontinental lithospheric mantle. The garnet data can be divided into five groups based on their Ca, Cr, and rare earth element (REE) contents. The REE profiles of the groups span from a near-primitive mantle signature to extremely sinusoidal, which can be accounted for by varying amounts of initial melt depletion and/or metasomatic reenrichment. Equilibration temperatures for garnet overlap with chromian spinel at temperatures from ~1,100° to 1,250°C, near the base of the sampling profile.

Using calculated minimum garnet equilibration pressures, the data suggest a geotherm relating to a model heat flow of ~40 mW/m2, which is similar to that previously determined using xenoliths from numerous intrusions in the eastern Dharwar craton to the south. Despite the similarity in their geotherms, previously reported geophysical data have suggested differences in the thickness and composition of the subcontinental lithospheric mantle between the two cratons. While modification or destruction of the Dharwar cratonic root after the breakup of Gondwana has been documented, seismic evidence suggests the same event may not have affected the Bundelkhand craton where the root appears to be preserved. If the subcontinental lithospheric mantle beneath the Bundelkhand craton escaped significant heating and metasomatism in the Mesozoic, then Cretaceous-aged kimberlite or lamproite intrusions may have greater potential to be diamond bearing, whereas intrusions of this age in the Dharwar or Bastar cratons do not.

By analyzing the figures and plots of Main-Travelled Roads, this paper will reveal humanism and classical sensibility, happy endings, and aesthetic value in it, and let readers understand the theme of the short stories thoroughly, and appreciate the Veritism comprehensively.
Exploring the Relationship between Obsessive-compulsive Characteristics and Symptoms of Eating Disorders in a Nonclinical Population
Authors: Paulson John
Published: February 2020

Previous research has documented similarities between symptoms of Obsessive-Compulsive Disorder (OCD), Anorexia Nervosa, and Bulimia Nervosa and elevated comorbidity between these conditions in clinical samples, with the relationship between OCD and Anorexia being stronger than between OCD and Bulimia. Researchers adopting a continuum view of psychopathology have also found that individuals with sub-clinical expressions of obsessive-compulsive symptoms resemble their clinical counterparts in several ways. The goal of the current study was to explore whether or not the observed relationship between obsessive-compulsive symptoms and eating disorder symptoms observed in clinical populations would also be observed in a nonclinical population. 264 participants from a college sample completed self-report measures of these symptoms. A positive correlation was found between scores on obsessive-compulsive, anorexia and bulimia instruments, and reflective of their clinical counterparts the relationship between obsessive-compulsive and anorexia symptoms was more significant than the one between obsessive compulsive symptoms and bulimia symptoms. Implications and limitations for research and clinical practice are discussed.
THE EUROPEAN SOCIAL MODEL AND THE INTERNATIONAL LABOUR ORGANIZATION – ORIGINS AND TRANSFORMATIONS
Authors: Scholz Wolfgang
Published: February 2020

The paper describes the cooperation between the International Labour Organisation and the new post- WWII European institutions – mainly Council of Europe and European Economic Community – in the fi eld of social security. At the centre of interest are ILO Convention 102 (1952) and the ILO’s “Ohlin report” (1956) and how they have co-shaped the evolution of the “European Social Model” in the long run. In its second part, the paper nests these developments into the paradigm change, that took place in the 1970s, from Keynesian to neo-liberal policies. While taking due account of ILO–EU divergence in social policy, which began in the 1960s, it describes in broad strokes the later impacts of the paradigm change on social policy formulation in the (new) “competition state”, in which welfare (“the ESM”) was no longer the goal but became a means to strengthen economic performance.

Optimization of Spring Back in Air V Bending Processing using Taguchi and RSM Method
Authors: özdemir Mustafa
Published: February 2020

In this study, springback behaviour of Dp600 (Dual Phase Steel) sheet material was investigated using air V bending technique.  As bending parameters, four different punch tip radii and four different sheet thicknesses were used. The springback values obtained from the experiments were compared with each other. At the same time, the experimental data were analysed with Response Surface Method (RSM) and Taguchi (L16) orthogonal array. The experimental data and the simulation results were found to be consistent. The signal-to-noise (S/N) ratio is used to determine the most appropriate parameter of minimum springback behaviour. Additionally, it is possible to estimate the optimal combination of the bending parameters. The signal-to-noise (S/N) ratio and the design of experiment (DOE) were utilised for the analysis of the experimental results. It was determined that the effect of these parameters on the air V bending process was based on springback behaviours.

In this study high relative density compaction of AISI 4140 steel powder compaction numerically investigated via different compaction velocities using Multi Particle Finite Element Method (MPFEM). 2D Analyses performed by three different particle geometry; 25µm, 35µm and 45µm in radius. Particle size effect also investigated via high relative density and compaction velocity. von Mises Power law evaluated for AISI 4140 steel powder and utilized to analysis. Results were plotted both in visually and graphically in aim to show effect of relative density, particle size, contact interactions and compaction velocity. The stress distribution through the height of die revealed out. A four-fold increase in compaction velocity increase the Equivalent von Mises stress 2% where the stress value can reach up to 3 times the yield stress. Stress values along the punch to the bottom of the die show a parabolic tendency with compaction velocity increase.

Authors: TAN Yan , WEI Wuguo
Published: February 2020

In this work, a large bypass ratio engine was taken as the research object. The impingement property of droplets with various diameters including SLD (Super-cooled Large Droplet) was obtained by Euler method based on Mundo model. The grid models of nose cone, fan, guild vanes in bypass duct and core duct were established in segments firstly. The mixed boundary was used to realize the data exchange between different flow fields. Then the Spalart-Allmaras turbulence model was applied to calculate the three dimensional engine flow field. Based on the flow field result, the droplet trajectory was calculated by Euler multiphase flow method. The LWC (Liquid Water Content), droplet collection efficiency and the effect of droplet diameter on impingement law were obtained. The method used in this paper and results could provide some references for subsequent engine icing calculation and anti-icing system design.
Methodology of Measuring Spraying the Droplet Flow of Polymers from Nozzle
Authors: Horiashchenko Serhiy Leonidovich
Published: February 2020

With a purpose for textile material coating applications, a process of spraying the polymer flow is considered. The equipment for determining the polymer drop size is designed. The formulas for estimating the size of polymer droplets are validated. For controlling and measuring the polymer drop size in real time, the multi-frequency phase method is suggested to be used. Classification is needed to find a category, within which the measurement will be done. Photos of various particles are obtained while experiments of spraying polymers are conducted. The sizes of those particles are determined. It is ascertained with the laser measurement and the corresponding software that when polymer drops get onto a textile material, they cool rapidly. The quality of the material is maintained. For properly spraying the polymer, the pressure of 6 MPa and the nozzle diameter of 2 mm are sufficient. The structure of the textile material along with the coating is maintained best with these parameters.
Positionsbestimmungen im Streit

Der Kampf der Sänger ist eine der Erzählungen E.T.A. Hoffmanns, die in der Forschung bislang vor allem negativ aufgenommen worden ist. Dass sich der Text, der den berühmten Dichterwettstreit auf der Wartburg zum Thema macht, auch ganz anders lesen lässt, zeigt diese Arbeit. Vor dem Hintergrund des mittelhochdeutschen Wartburgkriegs werden sowohl die Figuren als auch die Handlungskonzeption einer genauen Analyse unterzogen – mit dem bemerkenswerten Ergebnis, dass sich viele der auf den ersten Blick als Schwächen zu bezeichnenden Eigenheiten des Hoffmann’schen Textes nachvollziehbar auf den mittelalterlichen Prätext zurückführen lassen können.
Im Mittelpunkt der Arbeit stehen detaillierte Textanalysen, die sich verschiedener Methoden bedienen, ohne eine strikte Trennung zwischen ‚Älterer‘ und ‚Neuerer‘ Literaturwissenschaft zu verfolgen. Die Arbeit plädiert so dafür, auch mediävistische Überlegungen in die Neuere Literaturwissenschaft zu integrieren.

Avaliação de impacto ambiental causado por efluentes da estação de piscicultura Santa Rosa, Santarém/Pará
Authors: Correa Edinelson Saldanha , Monte Christiane , Nascimento Thiago Shinaigger Rocha do
Published: February 2020

No Brasil, a atividade da piscicultura vem aumentando nos últimos anos, proporcionada pelas condições ambientais, principalmente por conta do clima favorável, e a grande abundância de água, que é essencial para a criação de pescados. A qualidade da água é de grande importância para o sucesso da produção, já que é o meio onde se desenvolve a matéria prima dessa atividade, com isso suas características podem afetar a sobrevivência, reprodução, crescimento, ou seja, as ferramentas de manejo da atividade. Apesar do grande desenvolvimento e estímulo de órgãos especializados, observa-se ainda a carência em relação a informações e atos sobre possíveis impactos ao meio ambiente gerados pela atividade, visto que a água que alimenta os tanques de criação são provenientes de cursos d’água que retornam para o mesmo local, porém nos tanques de criação são acrescentadas várias substâncias, necessárias para o sucesso da produção, e que alteram as características da água, podendo assim causar impactos ambientais. O presente estudo objetivou analisar a qualidade dos efluentes gerados nos tanques de piscicultura e avaliar os possíveis impactos decorrentes desses efluentes sobre o corpo receptor. Todos os procedimentos analíticos foram realizados através de procedimentos padrões, descritos em Standard Methods for the Exammination of the Water and Wastewater (2012), foram coletados água de quatro pontos da Estação de piscicultura Santa Rosa visando obter informações sobre as alterações geradas na entrada de efluentes nos tanques e na saída no corpo receptor. Os resultados que a qualidade dos efluentes gerados nos tanques incidem alterações que possivelmente comprometem o ambiente aquático em relação à quantidade de concentrações de DBO e fósforo total que permaneceram com seus níveis superior do permitido. Na comparação dos pontos de montante (P1) e jusante (P4), os resultados revelaram que ocorre diferenças significativas. Os principais impactos observados foi a eutrofização e o comprometimento da qualidade da água do efluente no corpo receptor. Observa-se que mesmo não ocorrendo diferenças significativas nos pontos de montante e jusante, deve-se ter o cuidado no manejo, pois elas estão relacionadas com o meio aquático e na alteração de uma podendo ocasionar na morte dos peixes nos viveiros devido a sua sensibilidade e nas variações precipitadas principalmente do oxigênio dissolvido na água.
