Synthesis of Polyaniline/Scarlet 3R as a Conductive Polymer
Authors: Yonehara Takuya , Goto Hiromasa
Published: March 2020

Polyaniline (PANI) was prepared in the presence of the acidic dye scarlet 3R. Color tuning was performed on PANI through doping–dedoping processes and by changing the solvent used during the optical absorption spectroscopic measurements. The chemical structure of the resulting polymer–dye composite was analyzed using infrared absorption spectroscopy, and it showed the occurrence of secondary doping in m-cresol. The shape of the UV–Vis optical absorption spectra for the composite solution is dependent on the types of organic solvents used during the analysis, which was influenced by the conformation of PANI and the ionic interactions between PANI and scarlet 3R.

Published: March 2020

Versatile product protective coatings that deliver faster drying times and shorter minimum overcoat intervals that enable curing at faster line speeds and though lower energy consumption are often desired by coating manufacturers. Product protective coatings, based on silsesquioxane-modified diglycidyl ether of bisphenol-A (DGEBA) epoxy resin, are prepared through a glycidyl ring-opening polymerization using dicyandiamide (DICY) as a curing agent. As silsesquioxane modifier serves the octaglycidyl-polyhedral oligomeric silsesquioxane (GlyPOSS). To decrease the operational temperature of the curing processes, three different accelerators for crosslinking are tested, i.e., N,N-benzyl dimethylamine, 2-methylimidazole, and commercial Curezol 2MZ-A. Differential scanning calorimetry, temperature-dependent FT-IR spectroscopy, and rheology allow differentiation among accelerators’ effectiveness according to their structure. The former only contributed to epoxy ring-opening, while the latter two, besides participate in crosslinking. The surface roughness of the protective coatings on aluminum alloy substrate decreases when the accelerators are applied. The scanning electron microscopy (SEM) confirms that coatings with accelerators are more homogeneous. The protective efficiency is tested with a potentiodynamic polarization technique in 0.5 M NaCl electrolyte. All coatings containing GlyPOSS, either without or with accelerators, reveal superior protective efficiency compared to neat DGEBA/DICY coating.
Effect of the Sulfonation on the Swollen State Morphology of Styrenic Cross-Linked Polymers
Authors: Dalla Valle Chiara , Zecca Marco , Rastrelli Federico , Tubaro Cristina , Centomo Paolo
Published: March 2020

The chemical structure and morphology of a set of sulfonic gel-type poly(styrene-divinylbenzene) resins (2 mol% DVB) prepared with different synthetic approaches were investigated by solid state NMR, Inverse Size Exclusion Chromatography (ISEC), FT-IR and elemental analysis to compare their swollen state structure. FT-IR and solid state NMR clearly show that the sulfonation mainly occurs in the para- position with respect the main polymer chain. Sensible proportions of sulfone bridges were found in the materials obtained with oleum and chlorosulfonic acid. With oleum, the presence of the sulfone bridges is clearly associated to a reduced ability to swell in the water medium relative to the proton exchange capacity. This highlights the cross-linking action of the sulfone bridges according to ISEC results, showing a high proportion of a dense polymer fraction in the swollen material. An even higher degree of sulfone-bridging, lower swelling ability, and a high proportion of a dense polymer fraction in the swollen material are found in the resin obtained with chlorosulfonic acid. As a matter of fact, Cross Polarization Magic Angle Spinning Nuclear Magnetic Resonance (CP-MAS 13C-NMR), elemental analysis, and ion exchange capacity, show that oleum and chlorosulfonic acid produced resins with remarkably smaller pores and lower swollen gel volume in polar solvents, with respect to concentrated sulfuric acid.

Published: March 2020

With the development of population aging, the recognition of elderly activity in smart homes has received increasing attention. In recent years, single-resident activity recognition based on smart homes has made great progress. However, few researchers have focused on multi-resident activity recognition. In this paper, we propose a method to recognize two-resident activities based on time clustering. First, to use a de-noising method to extract the feature of the dataset. Second, to cluster the dataset based on the begin time and end time. Finally, to complete activity recognition using a similarity matching method. To test the performance of the method, we used two two-resident datasets provided by Center for Advanced Studies in Adaptive Systems (CASAS). We evaluated our method by comparing it with some common classifiers. The results show that our method has certain improvements in the accuracy, recall, precision, and F-Measure. At the end of the paper, we explain the parameter selection and summarize our method.
Mapping Urbanization and Evaluating Its Possible Impacts on Stream Water Quality in Chattanooga, Tennessee, Using GIS and Remote Sensing
Authors: Hall Jonah , Hossain A. K. M. Azad
Published: March 2020

Impervious surfaces (IS) produced by urbanization can facilitate pollutants’ movement to nearby water bodies through stormwater. This study mapped and estimated the IS changes in Chattanooga, Tennessee, using satellite imagery acquired in 1986 and 2016. A model was developed utilizing the Normalized Difference Vegetation Index coupled with density slicing to detect and map urbanization through IS growth. Urban growth was quantified at USGS HUC12 watershed level including stream riparian areas. The obtained results show a net growth of 45.12 km2 of IS with a heterogeneous distribution. About 9.96 km2 of this growth is within 90 m of streams, about 6% of the study site’s land cover. The Lower South Chickamauga Creek watershed experienced the largest urban growth with a change from 24.2 to 48.5 km2. Using the riparian zone percent imperviousness, a stream risk assessment model was developed to evaluate potential stream impairment due to this growth. Approximately 87, 131, and 203 km lengths of streams identified as potentially at high, very high, and extreme risks, respectively, to be impaired due to urban growth from the last 30 years. These findings would benefit to proactively implement sustainable management plans for the streams near rapidly urbanizing areas in the study site.
Compact Urban Form: Neighbouring and Social Activity
Authors: Shirazi M. Reza
Published: March 2020

Compact urban form has been widely suggested as a more sustainable development pattern that enhances different aspects of social liveability such as social exchange, collective interaction, and outdoor activity. Empirical research, however, challenges proposing a generic and universal understanding of compactness and its social advantages: compactness is perceived and lived differently in different socio-cultural contexts. This paper contributes to the call for gaining a more place-specific understanding from the compact urban form. To do so, it examines the social life of compact neighbourhoods in two study sites in Berlin. Social life is investigated by measuring the two dimensions of “neighbouring” and “social activities”: while the former explores how residents of the neighbourhood perceive different aspects of social life, the latter maps how urban space accommodates different types of social activity. Questionnaires and advanced mapping techniques are the primary sources of research obtained through intensive fieldwork and on-site observation. The research findings challenge some dominant assumptions attributed to the compact urban form orthodoxy: a compact neighbourhood can be perceived as safe, offer acceptable home and neighbourhood satisfaction, and, at the same time, suffer from low social networking and community engagement.

Authors: Choi Daeheon , Chung Chune Young , Hong Soon-Ihl Samuel , Young Jason
Published: March 2020

Many studies investigate collusion between political connections and firm performance, but Korean research on this topic is not very diverse. This study, based on financial data of listed Korean companies spanning the period from the 15th to the 19th Korean governments, analyzes whether political connections between governments and enterprises have a positive, negative, or no correlation with firm performance. The results show that the average return on assets for politically connected firms in the sample tends to be 10% higher than the corresponding value for sample firms that are not politically connected. Since existing studies measure political connections in a fragmented way, this study offers necessary implications for exploring the numerous structural problems of and solutions to the chronic issues currently faced by the Korean economy, as it investigates the economic policies from 1998 to 2018 and their influences on firm performance through the analysis of longer-term data.

Published: March 2020

Mathematical modelling to compute ground truth from 3D images is an area of research that can strongly benefit from machine learning methods. Deep neural networks (DNNs) are state-of-the-art methods design for solving these kinds of difficulties. Convolutional neural networks (CNNs), as one class of DNNs, can overcome special requirements of quantitative analysis especially when image segmentation is needed. This article presents a system that uses a cascade of CNNs with symmetric blocks of layers in chain, dedicated to 3D image segmentation from microscopic images of 3D nuclei. The system is designed through eight experiments that differ in following aspects: number of training slices and 3D samples for training, usage of pre-trained CNNs and number of slices and 3D samples for validation. CNNs parameters are optimized using linear, brute force, and random combinatorics, followed by voter and median operations. Data augmentation techniques such as reflection, translation and rotation are used in order to produce sufficient training set for CNNs. Optimal CNN parameters are reached by defining 11 standard and two proposed metrics. Finally, benchmarking demonstrates that CNNs improve segmentation accuracy, reliability and increased annotation accuracy, confirming the relevance of CNNs to generate high-throughput mathematical ground truth 3D images.

Published: March 2020

One of the essential activities for sustainable local economic development is continuous improvement of business environment which can be carried out through the business-friendly certification as objective benchmarking process, which is influenced by many factors - criteria that could be analyzed using multi-criteria decision-making methods. Determining criteria weights is the most important task regarding these methods for which a number of methodologies based on different approaches were developed. These methodologies could be generally divided into two groups: subjective and objective. Shortly, these methodologies quantify given preferences using knowledge of experts if they are subjective or using calculations from available data if they are objective. Methodologies from these two groups give different results in a wide range of values. Therefore, it is useful to create composite indicators using aggregation of both approaches in order to reduce the influence of their bad individual characteristics and, therefore, achieve a balanced symmetrical approach. The purpose of this paper is constructing one efficient model that solves a problem of the planning of sustainable local economic development in the Republic of Serbia. Our approach uses the aggregation of the entropy method, as one objective approach, and the analytical hierarchy process, as a subjective approach, in executing business-friendly certification process. The implementation of the proposed approach has been demonstrated as a part of a business-to-government (B2G) platform called “Multi-Criteria Support System for Analysis of the Local Economic Environment” in the City of Niš.

Published: March 2020

The current study aims to probe the impacts of entropy in a hydromagnetic unsteady slip flow of viscous fluid past an exponentially stretching sheet. Appurtenant similarity variables are employed to transmute the governing partial differential equations into a system of non-linear differential equations, which are analytically solved by utilizing the homotopy analysis method (HAM). Moreover, a shooting technique with fourth–fifth order Runge–Kutta method is deployed to numerically solve the problem. The impact of the physical parameters that influence the flow and heat transmission phenomena are sketched, tabulated and discussed briefly. Additionally, the impact of these parameters on entropy generation is thoroughly discussed by plotting graphs of the local entropy generation number and the Bejan number.

Authors: Zhang Sanxing , Ma Zhenhuan , Zhang Gang , Lei Tao , Zhang Rui , Cui Yi
Published: March 2020

Semantic image segmentation, as one of the most popular tasks in computer vision, has been widely used in autonomous driving, robotics and other fields. Currently, deep convolutional neural networks (DCNNs) are driving major advances in semantic segmentation due to their powerful feature representation. However, DCNNs extract high-level feature representations by strided convolution, which makes it impossible to segment foreground objects precisely, especially when locating object boundaries. This paper presents a novel semantic segmentation algorithm with DeepLab v3+ and super-pixel segmentation algorithm-quick shift. DeepLab v3+ is employed to generate a class-indexed score map for the input image. Quick shift is applied to segment the input image into superpixels. Outputs of them are then fed into a class voting module to refine the semantic segmentation results. Extensive experiments on proposed semantic image segmentation are performed over PASCAL VOC 2012 dataset, and results that the proposed method can provide a more efficient solution.

Published: March 2020

The cohomological resolution of mixed constraints is constructed and shown to give Gupta–Bleuler space of physical states. The differential space and so-called anomalous BRST complex is constructed in detail. Special structures associated with anomaly are demonstrated and proved to be of important significance. Finally, the formalism is applied to a spinorial system with second class constraints. In this case, the Laplace operators are proved to define the (irreducibility) equations for fields carrying arbitrary (high) spin.

Aspergillus flavus is the main producer of aflatoxin B1, one of the most toxic contaminants of food and feed. With global warming, climate conditions have become favourable for aflatoxin contamination of agricultural products in several European countries, including Serbia. The infection of maize with A. flavus, and aflatoxin synthesis can be controlled and reduced by application of a biocontrol product based on non-toxigenic strains of A. flavus. Biological control relies on competition between atoxigenic and toxigenic strains. This is the most commonly used biological control mechanism of aflatoxin contamination in maize in countries where aflatoxins pose a significant threat. Mytoolbox Af01, a native atoxigenic A. flavus strain, was obtained from maize grown in Serbia and used to produce a biocontrol product that was applied in irrigated and non-irrigated Serbian fields during 2016 and 2017. The application of this biocontrol product reduced aflatoxin levels in maize kernels (51–83%). The biocontrol treatment had a highly significant effect of reducing total aflatoxin contamination by 73%. This study showed that aflatoxin contamination control in Serbian maize can be achieved through biological control methods using atoxigenic A. flavus strains.

Authors: Grünwald Richard , Wang Wenling , Feng Yan
Published: March 2020

The Mekong River comprises six riparian states and supports the livelihood of more than 65 million people. Although the rapid joint river development enlarges the pie of benefits, it also deepens existing conflict of interests and motivating downstream countries to use more power to get better control over shared waters. The purpose of the article is to operationalize a new Transboundary Water Interaction Nexus (TWINS) and interpret interchange of cooperation and conflict between Laos, Thailand, Cambodia, and Vietnam about the Xayaburi hydropower dam in the last 19 years (2000–2019). Our results show that (1) there is significant disparity between the official and public attitude towards the Xayaburi dam, (2) since 2013, the debates about the Xayaburi dam issue has been substituted by other mainstream hydropower dams, (3) the Xayaburi dam indicates that hydropower dams are one of the national priorities that will be pursued at all cost, (4) Laos gained confidence and significant political leverage on downstream countries since the groundbreaking ceremony of the Xayaburi dam in November 2012, (5) failure of the Mekong River Commission’s Procedure of Notification and Prior Consultations (PNPCA) with the Xayauri dam motivated downstream countries to redesign the institutional arrangements and stakeholder consultations.

Trihalomethanes (THMs) are toxic disinfection by-products, formed in the reaction of chlorine with organic matter. This work aimed to study THM formation during a unique case study of managed aquifer recharge (MAR) with chlorinated desalinated seawater. THM formation was tested in the field, along a 3.0 m deep vadose zone gallery. Two small-scale experiments were conducted in the site, with untreated and with bromide spiked desalinated seawater. These were accompanied by a large-scale, ~1-month long operational MAR event. In the small-scale experiments, THM concentrations were shown to increase with bromide concentrations, with increasing dominance of the brominated species. Nevertheless, concentrations remained within the single µg/L range, which is an order of magnitude lower than drinking water regulations. Such low THM concentrations were also determined in the large-scale event. In both cases, THM formation occurred in the ponding water, without significant formation or degradation in the upper 3.0 m of the vadose zone. This study shows that MAR with chlorinated (<0.5 mg/L) desalinated seawater through sandy infiltration basins does not pose a threat to drinking water quality at this site.
Effect of Pressure Fluctuations and Flow Confinement on Shear Stress in Jet-Driven Scour Processes
Authors: Pagliara Simone , Palermo Michele
Published: March 2020

The effect of pressure fluctuations and flow confinement on shear stress still represents a challenging problem for hydraulic engineers. Only a few studies investigated such aspects, but they did not focus on jet-driven scour processes in granular bed material. Following a recent theoretical framework, this paper presents a novel analytical procedure to assess the effect of pressure fluctuations on the average shear stress for 2D equilibrium configuration, under steady, black water flow conditions. The analysis of experimental data evidences that published formulas underestimate the maximum shear stress, because of the significant flow confinement and the presence of rotating material in the scour hole. Therefore, based on the hydrodynamic similitude characterizing the jet diffusion in a confined environment, a new shear stress coefficient and a novel equation are proposed to estimate the maximum shear stress for the tested configuration.
Combined Electrocoagulation and Chemical Coagulation in Treating Brewery Wastewater
Authors: Swain Kimberly , Abbassi Bassim , Kinsley Chris
Published: March 2020

Significant over-strength discharge fees are often imposed on breweries for the disposal of high-strength effluent to sanitary sewers. In this research work, the removal performances of electrocoagulation (EC) compared with operating electrocoagulation and chemical coagulation in sequence (EC-CC) or vice-versa (CC-EC) was examined to determine the capability of treatment in reducing the strength of the wastewater. Optimal operating parameters regarding electrolysis time, initial pH, and applied power were determined in conjunction with nutrient removal performance, electrode consumption and energy usage. Combined EC-CC treatment has been demonstrated to be economically feasible for brewery wastewater applications from an energy consumption perspective due to the efficiency of nutrient removal and the reduction of sewer discharge costs. Treatment by EC-CC at 5 W for 20 min using aluminum electrodes resulted in enhanced and consistent removal efficiencies of 26%, 74%, 76%, and 85% for chemical oxygen demand (COD), reactive phosphorous (RP), total phosphorous (TP) and total suspended solids (TSS), respectively. Energy consumption was the main contributor to operating cost. By considering potential recovered over-strength discharge fees (ODF), EC-CC treatment is economically feasible and beneficial in a brewery wastewater application. The results demonstrated the effectiveness of the CC-EC process to remove phosphorous, organics and solids from brewery wastewater at lower power supply, so that the recovered ODF cost for CC-EC at 5 W-EC is 23% higher than at 10 W-EC.

Introduction: Bevacizumab, a humanized antibody against VEGF, is effective within the treatment of patients with several cancers. However, like several therapeutic agents, important side effects such as arterial thromboembolism, venous thromboembolism, hypertension, neutropenia, proteinuria, and hemorrhage are related to bevacizumab. Thromboembolism is one of the leading causes of morbidity and mortality in patients with cancer. Considerations have arisen relating to the chance of venous and arterial thromboembolism with the novel antiangiogenic agent bevacizumab: a recombinant humanized monoclonal antibody to a vascular endothelial growth factor which is wide employed in cancer treatment.

Theoretically, development of the city depends on labor resources. Generally, labor resources of the city come from periphery area. Developed infrastructure is a factor that mobilized labor resources from periphery to the city. There are two alternatives to the workers who come from periphery area; first they can stay in the city by renting apartment or the second as commuter. Many of the workers choose as commuter, so it is quite interesting to know what factors influence workers make choice as commuter. It is more specific whether factors such as income, length of work, age, distance, education level, and marital status influence the interest of workers to conduct circular migration. The analytical tool used is logistic regression analysis, Binary Regression Logistic. This research is a descriptive study that uses quantitative analysis using 1 dependent variable, namely interest in migration and six independent variables, namely income, length of working, age, distance, education level, and marital status. To achieve these objectives in this research logistic regression analysis was used, namely Binary Regression using primary data as many as 80 respondents. The results show that above variables; income, length of working, age, distance, level of education and marital status simultaneously and significantly influence on interest of workers in doing circulation migration to the Mataram City. Factors that partially influence significantly on the interest of workers doing migration to the Mataram City with a significance value with an alpha level of 5% are income, length of working, distance and level of education. While the age variable and marital status is not significant in effect.

COOPERATIVES AND PROFESSIONAL FOOTBALL: CAN A COOPERATIVE BE AN ADEQUATE LEGAL STRUCTURE FOR A CLUB? AN ANALYSIS UNDER THE PECOL PRINCIPLES
Authors: Ribeiro Maria de Fátima
Published: March 2020

Football clubs are traditionally organised under an associative legal form. Their objective is therefore not to obtain profit, but to pursue an activity that provides general benefits to the community (both to members and non-members of the association). However, severe financial and management issues have recently come to light in the professional football industry. Good governance is required in order to surpass those problems. The choice of legal form is a main driver of good governance, and that is the reason why under current Portuguese law only companies are allowed to enrol in professional football competitions. But this legislative option has not proven to be the best solution. In this paper, we assess the adequacy of the cooperative form as an organisational option, focusing on the substantial rules of PECOL (Principles of European Cooperative Law), which lays out the “ideal” legal identity of cooperatives, as well as on examples from specific jurisdictions.

Concrete is one of the most popular construction materials in the present world. Cement is the binding material used in concrete and its production requires large quantity of natural raw materials and generates enormous volume of greenhouse gases like CO2 . In developing and under developed countries, the primary sector forms the crucial part of the economy. The management of waste generated from agricultural sector is becoming a major concern due to their negative impact on the environment. Under this scenario, several researchers have developed supplementary cementitious materials (SCMs) from these by products that can be used as a cement replacing material in concrete. Many of these materials have shown great performance and they enhanced the fresh and hardened properties of concrete. This paper is aimed at reviewing the performance of various SCMs from agricultural waste materials. Reviewing such materials helps to identify and develop new materials
A Multiplicative Regularizer Augmented with Spatial Priors for Microwave Imaging
Authors: Bayat Nozhan , Mojabi Puyan
Published: March 2020

The standard weighted L2 norm total variation multiplicative regularization (MR) term originally developed for microwave imaging algorithms is modified to take into account
structural prior information, also known as spatial priors (SP), about the object being imaged. This modification adds one extra term to the integrand of the standard MR, thus, being referred to as an augmented MR (AMR). The main advantage of the proposed approach is that it requires a minimal change to the existing microwave imaging algorithms that are already equipped with the MR. Using two experimental data sets, it is shown that the proposed AMR (i) can handle partial SP, and (ii) can, to some extent, enhance the quantitative accuracy achievable from
microwave imaging.

Kehidupan berdemokrasi di Tanah Air terus mengalami perkembangan yang dinamis. Perbaikan demi perbaikan dilakukan dengan memetik pengalaman di masa lalu. Pun demikian dalam pelaksanaan pemilihan kepala daerah. Kemandekan hukum yang disebabkan tidak diperbolehkannya calon tunggal dalam pilkada dipecahkan Mahkamah Konstitusi. Pilkada tetap bisa berlanjut meski hanya ada satu pasangan calon yang maju. Hal itu kemudian diatur dalam Undang-Undang No 10 Tahun 2016 tentang Pilkada. Seyogianya proses pencalonan yang berujung pada calon tunggal merupakan kondisi kedaruratan. Hal demikian pun terjadi pada pemilihan Walikota Jayapura periode 2017-2022, pada saat pendaftaran calon wali kota-dan wakil wali kota di ikuti oleh tiga pasangan calon, dan ketika verifikasi berkas satu calon dinyatakan gagal alias tidak lulus administrasi oleh KPUD Kota Jayapura, dan hanya tersisa dua calon, namun dalam waktu berjalan satu calon lagi dinyatakan gagal oleh keputusan Mahkama Agung, dengan demikian maka pemilihan wali kota dan wakil wali kota tahun 2017 hanya di ikuti oleh satu pasangan calon. Adapun tujuan dalam adalah untuk mengetahui parisipasi masayrakat pada pemilihan Wali kota Jayapura Tahun 2017 Hasil penelitian menenjukan KPU Kota Jayapura secara resmi menetapkan Paslon Tunggal dalam Pemilihan Walikota dan Wakil Walikota Jayapura, tahun 2017, yang memenuhi syarat pasangan calon atas nama  DR. Benhur Tomy Mano, MM dan Ir. H. Rustan Saru, MM (BTM-Harus). Menurut  Mukri, Keputusan KPU Kota Jayapura Nomor 4  Kpts/Kpu-Kt-Jpr/I/ 2017 tentang penetapan Paslon Tunggal dalam pemilihan Walikota dan Wakil Walikota Jayapura tahun 2017 pada tanggal 11 Januari 2017  yang ditandatangani Ketua KPU Kota  Jayapura Yermis Numberi. Akibatnya partisipasi pemilih di Kota Jayapura, dalam pemilihan wali kota dan wakil wali kota mengalami penurunan 30 hingga 40 persen karena kurang adanya sosialisis kepada masayrakat. Kata Kunci: Demokrasi, Kotak Kosong, Pilkada
