Manufacturing a Refrigerator with Heat Recovery Unit
Authors: Kadhim Mustafa Mohammed 
Published: February 2018

This study aims to exploite the rejected heating energy from condenser and benefit from it to reheat the foods and other materials. It can also be employed to improve the coefficient of performance of a refrigerator at the same time by using approximately the same consumption electrical energy used to operate the compressor and refrigerator in general. This idea has been implemented by manufacturing of a refrigerator with using additional part has the same metal and condenser pipe diameters but its surface area does not exceed 40% from total surface area of the condenser and its design as an insulated cabinet from all sides to prevent heat leakage through it and located between the compressor and the condenser. Small electrical fan has been added inside this cabinet to provide a suitable air circulation and a homogenous temperature distribution inside the cabinet space. It is expected that the super heating energy of refrigerant (R134a) which comes out of the compressor would be removed inside this cabinet and this insist to condensate the refrigerant (cooling fluid) with a rate higher than that used in the normal refrigerator only. Three magnetic valves have been used in order to control the refrigerant flow in state of operation the refrigerator only or to gather with heating cabinet. To measure the temperatures at each process of the simple vapor compression refrigeration cycle, nine temperature sensors at input and output of each compressor, condenser and an evaporator in additional to input of cabinet and inside it and on evaporator surface have been provided. Five pressure gages have been used to measure the value of pressure and compare it for the two states of operation. The consumption of electrical energy can be calculated by adding an ammeter and a voltmeter and compare between the consumption energy of both states. The obtained results show that there is an improvement in the coeffecient of performance in state of operation the refrigerator with heat recovery cabinet by 20% more than that of the operation of refrigerator only. This improvement is due to the reduction in the condenser exit temperature by 4 to 6 C˚, and the super heat removing process in reheating cabinet. The temperature of the cabinet reachs to 60 C˚ which is a sufficient for the food heating. A small amount of refrigerant pressure reduction due to these additions, and its effect on the preformace of the refrigerator may be not considerable.

Published: February 2018

Meteor showers have been believed as one important source of metalic ion which is accumulated at ~100 km altitude and triggering the emergence of E-Sporadic layer. In this study, meteor showers catalogue derived from the observations in visual and radio windows were used to establish a model and temporal map of annual meteor showers expected to be observed in Sumedang, West Java. The map was compared to ionospheric observation data acquired in Sumedang throughout 2014-2015 in order to understand the relation between the showers of various fluxes to the occurrence of E-Sporadic layer. The analysis revealed that several meteor showers with geocentric speed of vG < 50 km/s possibly influence the occurrence of E-Sporadic layer, while the showers with vG > 50 km/s impact insignificantly. However, the seasonal variation of the percentage of E-Sporadic occurrence is far more dominant compared to its fluctuation during meteor showers.Abstrak Hujan meteor dengan fluks tinggi telah dipercaya sebagai salah satu sumber penting ion logam yang terkumpul pada ketinggian ~100 km dan memicu kemunculan lapisan E-Sporadis. Pada studi ini, katalog hujan meteor hasil pengamatan pada jendela visual dan radio digunakan untuk membangun model dan peta temporal hujan meteor tahunan yang diharapkan teramati di Sumedang, Jawa Barat. Peta tersebut dibandingkan dengan data pengamatan ionosfer di Sumedang sepanjang 2014-2015 untuk mengetahui keterkaitan antara hujan meteor dengan beragam fluks serta kemunculan lapisan E-Sporadis. Hasil analisis menunjukkan bahwa beberapa hujan meteor dengan kelajuan geosentris vG < 50 km/s memiliki indikasi berpengaruh pada kemunculan E-Sporadis, sementara hujan meteor dengan vG > 50 km/s tidak berdampak signifikan. Namun, variasi musiman dari persentasi kemunculan E-Sporadis jauh lebih dominan dibandingkan fluktuasinya saat hujan meteor.
DINAMIKA LAPISAN STRATOSFER DI BELAHAN BUMI UTARA DAN DAMPAKNYA TERHADAP WILAYAH TROPIS: STUDI KASUS MUSIM DINGIN 2012-2013 (STRATOSPHERIC DYNAMICS IN THE NORTHERN HEMISPHERE AND ITS IMPACT TO THE TROPICS: A CASE STUDY OF 2012-2013 WINTER)
Authors: Noersomadi NFN 
Published: February 2018

This research aims to investigate the dynamic of static stability (N2), potential energy of gravity waves (Ep), and vortex in the stratospheric northern hemisphere during 2012-2013 winter using temperature (T) and zonal wind (u) data from NCEP-DOE Reanalysis II. The results showed two occurrences of decreasing N2 ascociated with reversal of u in the first and third week of December 2012 were believed as a trigger of Sudden Stratospheric Warmings (SSW) on January 7, 2013. There was a flow from the polar to the tropics region during the SSW event. It caused the tropopause folding in the sub-tropic region indicated by the distribution of Ep on January 24, 2013. This tropopause folding triggered the convective activity over the Indonesian continents as shown by the negative OLR anomaly from 22 to 26 January 2013. The impact of SSW event in the northern hemisphere to the convective activity was 20%. This results showed the interaction between stratosphere and troposphere and also the teleconnection between the polar and the tropics. ABSTRAKPenelitian ini bertujuan menyelidiki dinamika stabilitas statis (N2), energi potensial gelombang gravitas (Ep), dan pusaran angin di lapisan stratosfer Belahan Bumi Utara (BBU) selama musim dingin 2012-2013 menggunakan data temperatur (T) dan komponen angin zonal (u) dari NCEP-DOE Reanalysis II. Hasil riset menunjukkan bahwa dua kejadian penurunan N2 pada pekan awal dan ketiga bulan Desember 2012 diyakini sebagai pemicu kejadian Sudden Stratosphere Warmings (SSW) tanggal 7 Januari 2013. Pada saat terjadi SSW terdapat aliran dari kutub menuju tropis. Aliran ini mengakibatkan terjadinya pelipatan lapisan tropopause di wilayah sub-tropis yang terlihat pada distribusi Ep tanggal 24 Januari 2013. Pelipatan lapisan tropopause ini kemudian memicu aktivitas konvektif di atas wilayah Indonesia yang ditandai oleh anomali OLR negatif antara tanggal 22-26 Januari 2013. Dampak kejadian SSW di BBU terhadap aktivitas konvektif di atas wilayah kepulauan Indonesia sebesar 20%. Hasil ini membuktikan interaksi antara lapisan stratosfer dan troposfer serta telekoneksi wilayah kutub dan tropis.

A great schism approaching? Towards a micro and macro public administration
Authors: Moynihan Donald 
Published: February 2018

As an emerging field, behavioral public administration (BPA) has spurred important new research, documenting human biases and heuristics in public sector contexts. In doing so, it has embraced Herbert Simon's call to draw from psychology to understand administrative behavior. To fulfill its potential, BPA should also pursue another goal of Simon: a normative aspiration toward design science, using its powerful analytical techniques to solve, and not just document, real administrative problems. Another challenge for BPA is understanding where it fits in the constellation of public administration research. One critique of BPA is that a focus on micro-level behavior leads to a neglect of big questions that were once central to public administration. But this tension may also signal the possibility of a productive division of labor, with a micro and macro public administration that addresses distinct questions, but which are connected by common research concepts

Published: February 2018

Introduction: Many studies have demonstrated an increased risk of obstetrical and neonatal complications after assisted reproductive techniques treatment compared to spontaneously conceived pregnancies. There are no data regarding these outcomes in Kosovo. The aim of our study was, to compare maternal, obstetric and neonatal parameters of in-vitro fertilization (IVF) conceived pregnancies complicated with hypertensive disorders (HD) versus uncomplicated spontaneous conceived pregnancies in Kosovo.Material and Methods: This observational study was undertaken at the Department of Gynaecology, University Clinical Centre of Kosova, during a two year period. A total of 104 pregnant women were included in the study. Maternal, obstetrical and neonatal parameters in both groups were assessed and compared. Statistical analysis was performed using SPSS 22.0 statistical software.Results: that conceived through IVF and had HD during pregnancy were older (p=0.0001), primipara (p=0.007), had multiple pregnancies (p=0.0001) and had worse obstetrical outcomes including cervix insufficiency (p=0.0001), premature rupture of membranes (p=0.0001), and delivery type (p=0.003) compared to women that conceived spontaneously. The only statistically significant differences in neonatal outcomes were in the Apgar1st (p=0.012) and Apgar5th (p=0.004) scores that were higher among babies born from mothers that conceived through IVF and had HD during pregnancy.Conclusions: Results of our study are in line with the results from other countries in regards to maternal demographic profile, except education level and employment, and obstetrical outcomes. However, there were no differences in regards to neonatal outcomes between the two groups of babies other than in the Apgar 1st and Apgar 5th scores.

Published: February 2018

Kurzfassung
Die Verbreitung der Elektromobilität in Deutschland liegt nach wie vor hinter den Zielen und Erwartungen von Politik und Gesellschaft zurück. Bisherige Hemmnisse der Mobilitätswende sind vor allem die relativ hohen Anschaffungskosten von Elektroautos, die politisch sanktionierten Strompreise, die begrenzten Reichweiten sowie der noch wenig komfortable Ladevorgang. Dem stehen wiederum zahlreiche Treiber wie der überlegene Wirkungsgrad, das emissionsfreie Fahren, die Schonung fossiler Ressourcen sowie der beeindruckende Fahrspaß gegenüber. Der vorliegende Beitrag fasst die aktuellen Treiber und Hindernisse der Mobilitätswende aus ökologischer, ökonomischer und sozialer Perspektive zusammen und leitet daraus Herausforderungen an die Technologieentwicklung und Produktionstechnik ab.
Effect of the Addition of ENR on Foam Properties of EVA/NR/Clay Nanocomposites
Authors: Lopattananon N. , Julyanon J. , Masa A. , Thongnuanchan B. 
Published: February 2018

Abstract
Elastomeric foams based on 60/40 EVA/NR blend nanocomposite were prepared by melt mixing EVA, NR and clay (5 phr) in an internal mixer, and later foamed with azodicarbonamide through compression molding. Epoxidized natural rubber (ENR) with epoxide content of 25 mole% was used as a compatibilizer to improve interfacial adhesion between EVA and NR. The addition effect of ENR concentration on the blending and properties of EVA/NR blend nanocomposite foams was studied. XRD and TEM results showed that the clay in the EVA/NR blends was intercalated and locally existed in the NR phase as well as at the interface between EVA and NR. The EVA/NR blend nanocomposites showed dispersed NR domains in continuous EVA phase. The addition of ENR into EVA/NR blend nanocomposites reduced the size of the dispersed NR phase, indicating that the blend miscibility was improved. Mechanistic model was proposed for the miscibility improvement of a two-phase structure of EVA/NR blend nanocomposite in the presence of ENR and clay dispersion. However, the improved blend morphology did not significantly affect the cell structure of EVA/NR blend nanocomposites. The observation of cell structure of EVA/NR blend nanocomposites suggested that the increased addition of ENR caused a little increase in cell density, and had no influence on cell size. Furthermore, with increasing addition level of ENR in the blend nanocomposite foams, the foam density slowly decreased, whereas the specific tensile strength slightly increased. The elastomeric recovery of blend nanocomposite foams decreased with increasing ENR content. The thermal conductivity of EVA/NR blend nanocomposite foams also decreased with more addition of ENR, which had beneficial result in improving thermal insulation property.
Numerical Predictions of Fiber Orientation for Injection Molded Rectangle Plate and Tensile Bar with Experimental Validations

Published: February 2018

Abstract
Fiber composites are the pinnacle of lightweight materials in the automotive industry. The orientation of the reinforcing fibers strongly affects the mechanical performance of the finished part. However, fiber orientation prediction with high accuracy is difficult for a complex flow field in practical injection molding. Recently, an objective model, iARD-RPR (Improved Anisotropic Rotary Diffusion and Retarding Principal Rate), has been significant to provide anisotropic distribution of fiber orientation, such as the well-known skin-shell-core structure. Micro-computed tomography (micro-CT) scan is a state-of-the-art technique for measuring a very high 3D resolution of a specimen's fiber orientation data. According to the micro-CT experiments and injection molding simulations with the iARD-RPR computation, we investigate changes in fiber orientation distributions at different concentrations in a rectangle plate, while the alignment of fibers found in weld line is revealed for tensile bar. Comparisons of the fiber orientation predictions with the validated experimental data are also presented herein.
Comparing decoding mechanisms for parsing argumentative structures
Authors: Afantenos Stergos , Peldszus Andreas , Stede Manfred 
Published: February 2018

Parsing of argumentative structures has become a very active line of research in recent years. Like discourse parsing or any other natural language task that requires prediction of linguistic structures, most approaches choose to learn a local model and then perform global decoding over the local probability distributions, often imposing constraints that are specific to the task at hand. Specifically for argumentation parsing, two decoding approaches have been recently proposed: Minimum Spanning Trees (MST) and Integer Linear Programming (ILP), following similar trends in discourse parsing. In contrast to discourse parsing though, where trees are not always used as underlying annotation schemes, argumentation structures so far have always been represented with trees. Using the ‘argumentative microtext corpus’ [in: Argumentation and Reasoned Action: Proceedings of the 1st European Conference on Argumentation, Lisbon 2015 / Vol. 2, College Publications, London, 2016 , pp. 801–815] as underlying data and replicating three different decoding mechanisms, in this paper we propose a novel ILP decoder and an extension to our earlier MST work, and then thoroughly compare the approaches. The result is that our new decoder outperforms related work in important respects, and that in general, ILP and MST yield very similar performance.

Published: February 2018

Abstract
The drag-based model for heliospheric propagation of coronal mass ejections (CMEs) is a widely used analytical model that can predict CME arrival time and speed at a given heliospheric location. It is based on the assumption that the propagation of CMEs in interplanetary space is solely under the influence of magnetohydrodynamical drag, where CME propagation is determined based on CME initial properties as well as the properties of the ambient solar wind. We present an upgraded version, the drag-based ensemble model (DBEM), that covers ensemble modeling to produce a distribution of possible ICME arrival times and speeds. Multiple runs using uncertainty ranges for the input values can be performed in almost real-time, within a few minutes. This allows us to define the most likely ICME arrival times and speeds, quantify prediction uncertainties, and determine forecast confidence. The performance of the DBEM is evaluated and compared to that of ensemble WSA-ENLIL+Cone model (ENLIL) using the same sample of events. It is found that the mean error is ME = −9.7 hr, mean absolute error MAE = 14.3 hr, and root mean square error RMSE = 16.7 hr, which is somewhat higher than, but comparable to ENLIL errors (ME = −6.1 hr, MAE = 12.8 hr and RMSE = 14.4 hr). Overall, DBEM and ENLIL show a similar performance. Furthermore, we find that in both models fast CMEs are predicted to arrive earlier than observed, most likely owing to the physical limitations of models, but possibly also related to an overestimation of the CME initial speed for fast CMEs.

Abstract
Transition disks with large dust cavities around young stars are promising targets for studying planet formation. Previous studies have revealed the presence of gas cavities inside the dust cavities, hinting at recently formed, giant planets. However, many of these studies are biased toward the brightest disks in the nearby star-forming regions, and it is not possible to derive reliable statistics that can be compared with exoplanet populations. We present the analysis of 11 transition disks with large cavities (≥20 au radius) from a complete disk survey of the Lupus star-forming region, using ALMA Band 7 observations at 0.″3 (22–30 au radius) resolution of the 345 GHz continuum, 13CO and C18O 3–2 observations, and the spectral energy distribution of each source. Gas and dust surface density profiles are derived using the physical–chemical modeling code DALI. This is the first study of transition disks of large cavities within a complete disk survey within a star-forming region. The dust cavity sizes range from 20 to 90 au radius, and in three cases, a gas cavity is resolved as well. The deep drops in gas density and large dust cavity sizes are consistent with clearing by giant planets. The fraction of transition disks with large cavities in Lupus is

, which is inconsistent with exoplanet population studies of giant planets at wide orbits. Furthermore, we present a hypothesis of an evolutionary path for large massive disks evolving into transition disks with large cavities.
