Published: June 2019

İsmet İnönü’nün Cumhurbaşkanı olduğu 11 Kasım 1938’den Demokrat Parti’nin iktidara geldiği 14 Mayıs 1950’ye kadar olan dönemde Türkiye’de deniz ulaşımı faaliyetleri ile bu faaliyetlerin ekonomiye olan yansımaları makalenin konusunu teşkil etmektedir. Çalışma, İnönü Dönemi’nde denizyolları faaliyetleri (1938-1950) ile sınırlandırılarak tek dönem halinde ele alınmıştır. Denizyolları faaliyetinin ekonomiye olan etkileri sayısal veriler ışığında değerlendirilmiştir. Çalışmanın kaynak materyalini, Başkanlık Cumhuriyet Arşivi Belgeleri, resmi yayınlardan; Türkiye Büyük Millet Meclisi (TBMM) Zabıt Ceridesi, kanunlar ve tutanak dergileri, Türkiye Cumhuriyeti Resmi Gazetesi, istatistik yıllıkları, ayın tarihi ve dönemin süreli yayınları arasında bulunan dergilerin makaleleri oluşturmaktadır. Konu incelenirken, dönemin dünyadaki deniz ulaşım çalışmaları alanında yaşanan gelişmeler göz önüne getirilerek gerekli değerlendirilmeler yapılmıştır. Çalışmada elde edilen sonuçlar şudur: İnönü’nün Cumhurbaşkanı olmasından kısa bir süre 3613 sayılı Kanunun kabul edilmesiyle deniz nakliyatı ve seyrüsefer emniyeti görevi Ulaştırma Bakanlığı uhdesine verilmiştir. Akabinde 7 Haziran 1939’da çıkarılan 3633 sayılı Kanunla da Denizbank feshedilerek Devlet Denizyolları İşletme Genel Müdürlüğü ve Devlet Limanları İşletme Genel Müdürlüğü adı altında iki idare teşkil edilerek denizyollarında yeni bir yapılanmaya gidilmiştir. Bunlara ilave olarak yapılan kanunî düzenlemelerle denizyolları alanında meydana gelen yasal boşluk giderilmeye çalışılmış, II. Dünya Savaşı sonucunda deniz filosunu güçlendirmeye yönelik Avrupa ve ABD’den gemi satın alımı yoluna ağırlık verilmiştir. Bu suretle Devlet Denizyolları ve armatörlere ait gemilerin sayı ve tonajlarının artırılmasının yanı sıra iç ve dış deniz seferleri ile bu seferlerden elde edilen gelirler de artırılarak milli ekonomiye önemli katkılar sağlanmıştır.

HALİL (KUT) BEY’İN TRABLUSGARP SAVAŞI’NDAKİ FAALİYETLERİ
Authors: ARSLANYÜREK Yaşar
Published: June 2019

XIX. yüzyılın sonlarından itibaren
özellikle de birçok Avrupalı devlet, güç kaybeden Osmanlı Devleti’nin
topraklarından pay almak amacıyla adeta birbirleriyle yarış içerisine girdi. Bu
devletlerden biri de İtalya’ydı.  

Trablusgarp
ve çevresi İtalya’nın emperyalist düşüncelerle ele geçirmeyi tasarladığı
yerlerdendi. Trablusgarp Vilayeti, Osmanlı Devleti’nin 360 senedir hâkimiyeti
altında bulundurduğu Kuzey Afrika’da bulunan bir toprağıydı. İtalya, burayı işgal
etmek amacıyla 1906 yılından itibaren işgale yönelik faaliyetlere başlamıştı. Nitekim
dönemin büyük devletleriyle bir takım anlaşmalar yapan İtalya, 1911 senesinde
Osmanlı Devleti’ne savaş ilan etti. İtalya, Trablusgarp’ı ve çevresini kısa
süre içinde kolaylıkla işgal etmeyi planlamıştı. Ancak gelişmeler hiç de
İtalya’nın beklediği gibi olmadı. İtalya, Trablusgarp’ta savaş ilan ettikten
sonra buraya Osmanlı Devleti tarafından, bölgedeki halkı direnişe geçirmek
amacıyla, genç subaylar gönderildi. Gönderilen bu subayların içerisinde Halil
Bey de bulunuyordu. Her subay bir cephede görevlendirildi. Bu bağlamda Halil Bey’e
de Homs Cephesi’nin sorumluluğu verildi.

Homs,
Mısrata, Bingazi, Tobruk ve Derne Cephelerinde genel anlamda kısıtlı imkânlara
karşın, İtalyanlara karşı başarılı savunmalar gerçekleştirildi. Bundan dolayı
İtalyanların etkisi genel itibarıyla sahil şeridinde kaldı. Bu başarıda bölgede
görevlendirilen Osmanlı subaylarının etkisi büyük oldu.

Authors: Miller Gwendolyn , Vael Aimee C. , Hires Kimberly A. , Eades Lee H.
Published: June 2019

The purpose of the quality improvement (QI) project was to provide parents nutritional education of recommended feeding practices as a means of encouraging parents to incorporate healthy parental role modeling behavior at home and reduce pediatric body mass index (BMI). The plan-do-study-act was the chosen methodology applied to initiate a practice change within the current treatment of childhood obesity in the outpatient pediatric setting [1, 2]. There was a total of 9 parent/child dyad participants who completed the study. The inclusionary criteria for the study was the child was 2-5 years old, with a body mass index (BMI) greater than or equal to 85% according to the pediatric growth curve with accompanied parents/ guardians that was able to give consent. The study demonstrated that there was a statistically significant difference in the pre-survey scores (M=19.00, SD=5.39) and the post-survey scores (M=16.44, SD=3.32); t (8) =2.34, p =.048; clarifying that lower/decreased survey scores demonstrated an improvement in parental knowledge. There was not a significant difference be- tween the pre-educational BMI (M=18.27, SD=.75) and the post-educational BMI (M=18.39, SD=1.16) of study participants; t (8) =-.35, p=.734. This study used the Parental Role Model Assessment tool to compare the pre-interventional parental role modeling scores to the post-interventional role modeling scores within the pediatric home. The quality improvement (QI) team determined that the post interventional Parental Role Model Assessment scores decreased which suggested that the educational intervention delivered by the pediatric provider on positive parental role modeling was retained and modeled by the parents within the pediatric home over a 3 month period. The team concludes that enhancing standards of practice within the pediatric primary care setting to allow for improving parental nutritional/ lifestyle knowledge deficits and providing education to strengthen positive parental role modeling will act to enhance quality-health outcomes within the pediatric obese/overweight population.

Emekli dernekleri yaşlıların emeklilik
sonrası çeşitli ihtiyaçlarını karşılayan sivil toplum kuruluşlarıdır. Bu
dernekler genellikle emekli üyelerin karşılaşabilecekleri bazı sorunların
çözümüne katkı sağlamayı hedeflenmektedir. Emekli dernekleri, aktif iş
yaşamından çekilme ile sosyal sermaye kaybı yaşayan yaşlılar için alternatif
sosyal sermaye kaynağı olabilmektedir. Bu dernekler meslek temelli sosyal
ilişkilerin sürekliliğini sağlayabilmeye yardımcı olmaktadır. Türkiye’deki mevcut literatüre
bakıldığında, emekli derneklerinin yaşlıların sosyal sermayelerine katkısının
yeterince analiz edilmediği görülmektedir. Bu çalışma bir dayanışma örüntüsü
olarak ortaya çıkan emekli derneklerinin yaşlıların sosyalleşme ilişkilerine
katkısını ortaya çıkarmayı amaçlanmaktadır. 
Bu amaç doğrultusunda İstanbul’daki çeşitli emekli derneklerinde 15 Mart
-30 Mayıs 2014 tarihleri arasında bir saha araştırması yürütülmüştür. Emekli
derneklerinde yönetici ve gönüllü üye statüsündeki 12 kişi ile görüşme

When Water Swims in Water, Will it Float, or Will it Sink? Or: What Drives Currents in the Ocean?
Authors: Glessmer Mirjam S.
Published: June 2019

The ocean is continuously in motion. A large part of this motion is driven by water with different temperatures and different concentrations of dissolved salts in different areas of the ocean. In this article, we will discuss how these differences in ocean water can create ocean currents. We also tell you how to perform a simple experiment that can easily be done at home, to illustrate the formation of ocean currents.
On the Determination of the Aerodynamic Damping of Wind Turbines Using the Forced Oscillations Method in Wind Tunnel Experiments
Authors: Fontecha Robert , Kemper Frank , Feldmann Markus
Published: June 2019

The development of wind turbine technology has led to higher and larger wind turbines with a higher sensitivity to dynamic effects. One of these effects is the aerodynamic damping, which introduces favorable damping forces in oscillating wind turbines. These forces play an important role in the turbine lifetime, but have not yet been studied systematically in detail. Consequently, this paper studies the plausibility of determining the aerodynamic damping of wind turbines systematically through wind tunnel experiments using the forced oscillation method. To this end, a 1:150 scale model of a prototype wind turbine has been fabricated considering Reynolds number effects on the blades through XFOIL calculations and wind tunnel measurements of airfoil 2D-section models. The resulting tower and wind turbine models have been tested for different operation states. The tower results are approximate and show low aerodynamic damping forces that can be neglected on the safe side. The measured aerodynamic damping forces of the operating turbine are compared to existing analytic approaches and to OpenFAST simulations. The measured values, although generally larger, show good agreement with the calculated ones. It is concluded that wind tunnel forced oscillations experiments could lead to a better characterization of the aerodynamic damping of wind turbines.
The Use of CFD for the Design and Development of Innovative Configurations in Regenerative Glass Production Furnaces
Authors: Cravero Carlo , De Domenico Davide
Published: June 2019

The limitation of nitrogen oxides emissions is nowadays a challenge in several engineering fields. Recent European regulations have reduced the maximum NOx emissions and therefore forced the glass production sector to develop emission reduction strategies. Two different systems have been developed within the framework of the European LIFE project and are currently applied to glass regenerative furnaces: the Waste Gas Recirculation (WGR) and the Hybrid Air Staging (HyAS). The above systems are primary NOx reduction strategies because they both operate to control the combustion evolution. Both WGR and HyAS systems have been conceived with the extensive use of Computational Fluid Dynamics (CFD) models: design strategies for both systems have been developed based on the use of CFD and are currently under use by glass furnace designers. In the present work, the CFD procedures routinely used for the design of the above systems are described. The systems effectiveness, due to the harsh conditions in the industrial installation, can be tested with oxygen concentration measurements inside the regenerators. The oxygen concentration is correlated to the flame evolution and therefore to the nitrogen oxides formation. For the above reason, the models have been validated with experimental data from pilot furnaces using measured values of O2 mole fraction. The CFD procedures are described in the paper together with their application to different configurations.
Admittance Reshaping Control Methods to Mitigate the Interactions between Inverters and Grid
Authors: Yang Ling , Chen Yandong , Luo An , Huai Kunshan
Published: June 2019

With the increasing impedance coupling between inverters and grid caused by the phase-locked loop (PLL), traditional three-phase inverters suffer from the harmonic distortion or instability problems under weak grid conditions. Therefore, the admittance reshaping control methods are proposed to mitigate the interactions between inverters and grid. Firstly, a dynamics model of traditional inverter output admittance including main circuit and PLL is developed in the direct-quadrature (dq) frame. And the qq channel impedance of the inverter presents as a negative incremental resistance with the PLL effect. Secondly, two admittance reshaping control methods are proposed to improve the system damping. The first reshaping technique uses the feedforward point of common coupling (PCC) voltage to modify the inverter output admittance. The second reshaping technique adopts the active damping controller to reconstruct the PLL equivalent admittance. The proposed control methods not only increase the system phase margin, but also ensure the system dynamic response speed. And the total harmonic distortion of steady-state grid-connected current is reduced to less than 2%. Furthermore, a specific design method of control parameters is depicted. Finally, experimental results are provided to prove the validity of the proposed control methods.
Real Levelized Cost of Energy with Indirect Costs and Market Value of Variable Renewables: A Study of the Korean Power Market
Authors: Hwang Sung-Hyun , Kim Mun-Kyeom , Ryu Ho-Sung
Published: June 2019

A levelized cost of energy (LCOE) is a methodology for comparing power generation costs in the transition to renewable energy (RE). However, the major limitation of evaluating RE based on the LCOE is that it does not consider indirect costs, such as the environmental and curtailment effect. This paper proposes the real LCOE (rLCOE) approach that accounts for indirect and direct generation costs. The mathematical approach to estimating indirect costs is derived from economic theory. The indirect effects, which quantify all benefits generated due to RE, is related to the variability of the share RE in the energy generation mix. The rLCOE enhances the accuracy of the economic comparison of power generation costs and the derivation of the optimal quantities of RE because external effects are incorporated into the LCOE principles. This approach has taken into account electricity demand, fuel prices, and environmental costs for each energy source to adequately compare generation costs. Simulations have been performed to demonstrate the application of the rLCOE approach in the Korean power market. Here, the unit variation of costs with the RE share were analyzed. The results show that indirect cost savings of an additional unit of RE begin to fall in scenario 3 in contrast to the result of LCOE approach indicating higher generation costs with RE share, especially, the proportion of RE in the generation mix is higher than 20%. Thus, the optimal power generation can be evaluated using the rLCOE approach.
3D Printing for Energy-Saving: Evidence from Hydraulic Manifolds Design
Authors: Zhang Jun-hui , Liu Gan , Ding Ruqi , Zhang Kun , Pan Min , Liu Shihao
Published: June 2019

With the compact circuit layout and small size, hydraulic manifolds sometimes cause high pressure loss. The purpose of this paper is to investigate the pressure loss under different circumstances with various geometry features and present solutions to reduce pressure loss. The pressure loss performance is evaluated by both experimental and numerical methods. Verified by the experiments, the numerical simulations are qualified to depict the correct trend of the pressure drop. After the basic analysis of traditional passages, three novel forms are proposed, which are very hard to be manufactured by a common method. Furthermore, the geometrical features are selected optimally by means of full factorial experiments to balance the pressure loss and space requirement. Moreover, taking advantage of 3D printing, it is possible to build the passages in novel forms which are beyond the capacity of conventional manufacturing. Results show that the pressure loss can be reduced considerably by adopting a smooth transition, where the reduction can reach up to 50%.
Fuzzy Neural Network Control of Thermostatically Controlled Loads for Demand-Side Frequency Regulation
Authors: Qu Zhengwei , Xu Chenglin , Ma Kai , Jiao Zongxu
Published: June 2019

In this paper, a fuzzy neural network controller for regulating demand-side thermostatically controlled loads (TCLs) is designed with the aim of stabilizing the frequency of the smart grid. Specifically, the balance between power supply and demand is achieved by tracking the automatic generation control (AGC) signal in an electric power system. The particle swarm optimization (PSO) and error back propagation (BP) algorithms are used to optimize the control parameters and consequently reduce the tracking errors. The fuzzy neural network can be applied to solve load control problems in power systems, since its self-learning and associative storage functions can deal with the highly nonlinear relationship between input and output. Simulation results show the advantage of the fuzzy neural network control scheme in terms of frequency regulation error and consumer comfort.
Increasing the Competitiveness of Tidal Systems by Means of the Improvement of Installation and Maintenance Maneuvers in First Generation Tidal Energy Converters—An Economic Argumentation
Authors: Segura Eva , Morales Rafael , Somolinos José A.
Published: June 2019

The most important technological advances in tidal systems are currently taking place in first generation tidal energy converters (TECs), which are installed in areas in which the depth does not exceed 40 m. Some of these devices are fixed to the seabed and it is, therefore, necessary to have special high performance ships to transport them from the base port to the tidal farm and to subsequently recover the main units of these devices. These ships are very costly, thus making the installation costs very high and, in some cases, probably unfeasible. According to what has occurred to date, the costs of the installation and maintenance procedures depend, to a great extent, on the reliability and accessibility of the devices. One of the possible solutions as regards increasing system performance and decreasing the costs of the installation and maintenance procedures is the definition of automated maneuvers, which will consequently influence: (i) an increase in the competitiveness of these technologies; (ii) a reduction in the number and duration of installation and maintenance operations; (iii) less human intervention, or (iv) the possibility of using cheaper general purpose ships rather than high cost special vessels for maintenance purposes, among others. In this research, we propose a definition of the procedures required for the manual and automated installation and maintenance maneuvers of gravity-based first generation TECs. This definition will allow us to quantify the costs of both the manual and automated operations in a more accurate manner and enable us to determine the reduction in the cost of the automated installation and maintenance procedures. It will also enable us to demonstrate that the automation of these maneuvers may be an interesting solution by which to improve the competitiveness of tidal systems in the near future.
Narratives Across Scales on Barriers and Strategies for Upscaling Forest Restoration: A Brazilian Case Study
Authors: Schweizer Daniella , van Kuijk Marijke , Meli Paula , Bernardini Luis , Ghazoul Jaboury
Published: June 2019

Several countries worldwide have committed to forest and landscape restoration (FLR) through ambitious pledges in numbers of hectares to be restored. As the implementation of these commitments happens within countries, different actors from global to local scales must negotiate the “what, where and how” of specific forest restoration projects. We interviewed actors at national, state and local scales to gather their narratives regarding barriers and strategies for upscaling forest restoration and compared the narratives among them and with those that prevail in the global literature on FLR. We based the local scale in four Atlantic Forest landscapes. We classified the narratives gathered according to three discourses commonly used in environmental policy arenas: (1) ecological modernization, advocating market solutions; (2) green governmentality, with its emphasis on technocratic solutions; and (3) civic environmentalism promoting governance. Brazilian legislation with its mandate of forest restoration in private lands appeared as the main restoration driver in the interviews. However, when political will for enforcement weakens, other strategies are needed. An ecological modernization narrative, around increasing funding, incentives, market and investments, prevailed in the narratives on barriers and strategies for all actors from the global to the local scales. Similarities nevertheless diminished from the global to the local scale. The narratives of national actors resembled those found in the global literature, which emphasize strategies based on increased capacity building, within a green governmentality narrative, and governance arrangements, a civic environmentalist narrative. These narratives appeared less at state scales, and were almost absent at local scales where forest restoration was perceived mostly as a costly legal mandate. Similar narratives across all actors and scales indicate that a focus on improving the economics of restoration can aid in upscaling forest restoration in Brazilian Atlantic Forest landscapes. However, discrepant narratives also show that inclusive governance spaces where the negotiation of FLR interventions can take place is key to increase trust and aid implementation.

Antimicrobial resistance (AMR) is one of the biggest issues facing global public health. In 2017, Italy adopted its first National Action Plan on Antimicrobial Resistance 2017–2020, which works through the synergy between national, regional, and local levels. In the framework of a Regional Action Plan on healthcare-associated infections and AMR prevention, the Sicilian Health Authority of the Sicilian Region, Southern Italy, has implemented a surveillance system of antibiotic consumption in hospitals, in the community, and of resistance rates (RRs) in hospital settings. Data on antibiotic consumption and on antibiotic RRs have been collected from 2015 to 2017 from pharmacies and laboratories of participating hospitals and from community, respectively. Data on antibiotic consumption showed that the most consumed antibiotics in hospitals were fluoroquinolones in 2015, penicillin in 2016, and beta-lactams in 2017. From 2015 to 2017, data on Klebsiella pneumoniae showed significant increasing RRs to all antibiotic classes, except to carbapenems. RRs of third-generation cephalosporins and carbapenems Escherichia coli showed significant decreasing trends. RRs of the other microorganisms did not change significantly during the study period. The results from the present study show that in Sicily, the use of antibiotics and RRs for selected microorganisms are at a high level. Immediate strategies are needed to decrease the inappropriate usage of antibiotics and control the spread of AMR.

Published: June 2019

The complex process of gestation involves significant biological, psychological, and social changes for both women and men looking toward the same direction. The aim of this study was to analyze changes occurring in affective health between the members of a couple during pregnancy. For this, a cross sectional descriptive study using Sternberg’s questionnaire based on his Triangular Theory of Love (intimacy, passion, and commitment) was implemented. A total of 180 couples participated in the study. Data were collected four times during pregnancy: at the beginning, during the first trimester, the second trimester, and during the third trimester. The level of intimacy was higher at the beginning of pregnancy (123.93 ± 9.67), the same as the level of passion (119 ± 9.83). The commitment score in women was, in general, higher than in men. The commitment score in men increased at the beginning of the third trimester (124.31 ± 7.72). Statistically significant differences between the sexes were found for the level of commitment at the beginning of the pregnancy (p = 0.001) and at the third trimester (p = 0.008), these scores being higher for women than for men. No significant differences between men and women were found for the remaining components of the triangle. During pregnancy, no significant changes were found regarding overall affection throughout the entire period.
The Dualistic Effect of COX-2-Mediated Signaling in Obesity and Insulin Resistance

Published: June 2019

Obesity and insulin resistance are two major risk factors for the development of metabolic syndrome, type 2 diabetes and associated cardiovascular diseases (CVDs). Cyclooxygenase (COX), a rate-limiting enzyme responsible for the biosynthesis of prostaglandins (PGs), exists in two isoforms: COX-1, the constitutive form, and COX-2, mainly the inducible form. COX-2 is the key enzyme in eicosanoid metabolism that converts eicosanoids into a number of PGs, including PGD2, PGE2, PGF2α, and prostacyclin (PGI2), all of which exert diverse hormone-like effects via autocrine or paracrine mechanisms. The COX-2 gene and immunoreactive proteins have been documented to be highly expressed and elevated in adipose tissue (AT) under morbid obesity conditions. On the other hand, the environmental stress-induced expression and constitutive over-expression of COX-2 have been reported to play distinctive roles under different pathological and physiological conditions; i.e., over-expression of the COX-2 gene in white AT (WAT) has been shown to induce de novo brown AT (BAT) recruitment in WAT and then facilitate systemic energy expenditure to protect mice against high-fat diet-induced obesity. Hepatic COX-2 expression was found to protect against diet-induced steatosis, obesity, and insulin resistance. However, COX-2 activation in the epidydimal AT is strongly correlated with the development of AT inflammation, insulin resistance, and fatty liver in high-fat-diet-induced obese rats. This review will provide updated information regarding the role of COX-2-derived signals in the regulation of energy metabolism and the pathogenesis of obesity and MS.

Prolonged dexamethasone (Dex) administration leads to serious adverse and decrease brain and heart size, muscular atrophy, hemorrhagic liver, and presence of kidney cysts. Herein, we used an untargeted proteomic approach using liquid chromatography-tandem mass spectrometry (LC-MS/MS) for simultaneous identification of changes in proteomes of the major organs in Sprague–Dawley (SD rats post Dex treatment. The comparative and quantitative proteomic analysis of the brain, heart, muscle, liver, and kidney tissues revealed differential expression of proteins (n = 190, 193, 39, 230, and 53, respectively) between Dex-treated and control rats. Functional network analysis using ingenuity pathway analysis (IPA revealed significant differences in regulation of metabolic pathways within the morphologically changed organs that related to: (i) brain—cell morphology, nervous system development, and function and neurological disease; (ii) heart—cellular development, cellular function and maintenance, connective tissue development and function; (iii) skeletal muscle—nucleic acid metabolism, and small molecule biochemical pathways; (iv) liver—lipid metabolism, small molecular biochemistry, and nucleic acid metabolism; and (v) kidney—drug metabolism, organism injury and abnormalities, and renal damage. Our study provides a comprehensive description of the organ-specific proteomic profilesand differentially altered biochemical pathways, after prolonged Dex treatement to understand the molecular basis for development of side effects.

Published: June 2019

In the present study, data generated from nanoindentation were used in order to reconstruct the surface constituent phases of mortar grids through machine learning algorithms. Specifically, the K-Means algorithm (unsupervised learning) was applied to two 49 measurement (7 × 7) datasets with information about the modulus (E) and hardness (H) in order to discover the underlying structure of the data. The resulting clusters from K-Means were then evaluated and values range assigned so as to signify the various constituent phases of the mortar. Furthermore, another dataset from nanoindentation containing information about E, H, and the surface colour of the measured area (obtained from an optical microscope) was used as the training set in order to develop a random forests model (supervised learning), which predicts the surface colour from the E and H values. Colour predictions on the two 7 × 7 mortar grids were made and then possible correlations between the clusters, signifying constituent phases, and the predicted colours were examined. The groupings of data in the clusters (phases) corresponded to a unique surface colour. Finally, the constituent phases of the mortar grids were reconstructed in contour plots by assigning the corresponding cluster of the K-Means algorithm to each measurement (position in the grid).

Published: June 2019

The effect of graphene oxide (GO) on the crystallization of calcium carbonate (CaCO3) is explored in this paper. Precipitation of CaCO3 was carried out by bubbling carbon dioxide (CO2) through tricalcium silicate (C3S) hydration solution with different graphene oxide admixture contents (0.2%, 1% and 2% mass ratios based on C3S). The polymorph, morphology, crystal size and particle size of CaCO3 were evaluated using X-ray diffraction (XRD), an environmental scanning electronic microscope (ESEM), and laser particle size analysis. The results showed that addition of GO was able to promote the conversion of CaCO3 to a calcite crystal phase with higher thermal stability and crystallinity than the control. However, as the dosage of GO increased, the growth of the calcite crystal particles was somewhat suppressed, resulting in a decrease in the crystal particle size and a narrow particle size distribution. When the amount of GO was 0.2%, 1% and 2%, the crystal size of the calcite was 5.49%, 12.38%, and 24.61% lower than that of the sample without GO, respectively, while the particle size of the calcite also decreased by 17.21%, 39.26%, 58.03%, respectively.

Published: June 2019

The interaction between three widely used antimalarial drugs chloroquine, primaquine and amodiaquine with acrylamide dimer and trimer as a hydrogel model, were studied by means of density functional theory calculation in both vacuum and water environments, using the functional wb97xd with 6-31++G(d,p) basis set and polarizable continuum model (C-PCM) of solvent. According to binding energy, around −3.15 to −11.91 kJ/mol, the interaction between antimalarial compounds and hydrogel model are exothermic in nature. The extent of interaction found is primaquine > amodiaquine > chloroquine. The natural bond orbital (NBO) calculation and application of second-order perturbation theory show strong charge transfer between the antimalarial and hydrogel model. In addition, the results suggest these interactions are polar in nature, where hydrogen bonds play a principal role in stabilization of the complex. Comparing with the gas-phase, the complexes in the water environment are also stable, with suitable values of Log P (Partition coefficient), and dipolar momentum. Consequently, these results encourage to test acrylamide hydrogels as antimalarial delivery systems.
Beyond Essentialist Interreligious Education: Insights with a Whiteheadian Perspective of Multiplicity
Authors: Lee Joung Chul
Published: June 2019

In the late twentieth century, interreligious education emerged as a way to transform one’s attitude toward other religions and reduce religious prejudice. This article addresses the philosophical aspects of this practice, in particular the problems that arise when an essentialist approach is accommodated. The problems include the why (philosophical rationale), the who (subject and participant), the what (content), and the future (purpose). In response, the author explores how a relational approach grounded in a Whiteheadian philosophy of multiplicity would allow us to understand interreligious education differently. The article finds that a relational approach can help us imagine and embody interreligious education in a more humanizing, inclusive, and transformative way.
Policy Mobilities and the China Model: Pairing Aid Policy in Xinjiang

This paper seeks to make a contribution to on-going debates about how to conceptualize the “China model” by emphasizing the top-down regional coordination strategies of China in the context of policy mobilities. The notion of policy mobilities is a hot issue through which to analyze how successful political ideas are often mobilized, imitated, adapted, and reused in new places by various actors through learning the global “best” experiences. However, policy mobilities should be employed as a frame within a specific political-economy context and the “institutional geometries”, especially in China which is characterized by centralization of state power and impressive economic growth recently. In this paper, we argue that the case of pairing aid policy in China, in which diffused policy ideas regarding advanced development initiatives are transferred and adopted in relatively underdeveloped areas, serves as a key part of the China model to balance regional development. Drawing on a case study of pairing aid policy in Xinjiang, the paper explores the ways in which the advanced industries, cadres, and investments from 19 developed coastal provinces or cities were mobilized by the state power network: (1) Transferring cadres and technicians from developed areas to directly work in Xinjiang temporally; (2) mobilizing the industrial policy package to attract labor-intensive and resource-oriented firms located in the industrial zones of Xinjiang; and (3) mobilizing a part of fiscal investments from donating areas to expand recipients’ direct investments. By doing this, we illustrate how higher-level authority can develop more state powers to transfer regional cadres, capital, and projects from developed areas to less developed ones, as well as how mobilized policies can be entrepreneurially adopted and flexibly mutated in the context of various local conditions.

Published: June 2019

Este trabalho estuda a evolução pós-tecnogênica da paisagem (processos geomorfológicos e formação de biomas antropogênicos) em uma área de expansão urbana no município de Guarulhos (SP), denominada Parque Continental II. O processo de formação dos terrenos antropogênicos da área, ocorrido na década de 1990, estudado anteriormente por outros pesquisadores (assim como sua cobertura vegetal), insere-se num sistema tecnogênico de urbanização periférica que implicou processos de degradação (escavação) e agradação (aterramento e sedimentação induzida correlativa à erosão acelerada). A particularidade do caso estudado consiste em que o processo de urbanização propriamente dito (loteamento) não foi implementado, tendo os terrenos evoluído sem intervenções significativas após os distúrbios iniciais. Foram revisados e atualizados o mapeamento e a classificação desses terrenos artificiais, caracterizados os processos de evolução geomorfológica e verificadas as particularidades dos fenômenos de sucessão ecológica, de forma a caracterizar um sistema de sucessão tecnogênica, ou seja, um conjunto de comunidades ecológicas desenvolvidas em uma paisagem fortemente impactada pela agência geológica humana. Em função da relação entre tais comunidades (ou subsistemas de sucessão tecnogênica) e as características do substrato tecnogênico, foram classificadas e mapeadas áreas de tecnobiomas (ecossistemas formados por associações de espécies e novos substratos derivados da transformação da paisagem). Considera-se, em decorrência, a conveniência da preservação de tal área de diversidade tecnogênica e ecológica.
