Transparent conducting oxides (TCOs) are ubiquitous in modern consumer electronics. SnO2 is an earth abundant, cheaper alternative to In2O3 as a TCO however, its performance in terms of electrical properties lags behind that of In2O3. Based on the recent discovery of mobility and conductivity enhancements in In2O3 from resonant dopants, we use a combination of state-of-the-art hybrid density functional theory calculations, high resolution photoelectron spectroscopy and semiconductor statistics modelling to understand what the optimal dopant is to maximise performance of SnO2-based TCOs. We demonstrate that Ta is the optimal dopant for high performance SnO2, as it is a resonant dopant which is readily incorporated into SnO2 with the Ta 5d states sitting ~1.4 eV above the conduction band minimum. Experimentally, the electron effective mass of Ta doped SnO2 was shown to be 0.23m0, compared to 0.29m0 seen with conventional Sb doping, explaining its ability to yield higher mobilities and conductivities.

Authors: Kempt Roman , Kuc Agnieszka , Heine Thomas
Published: November 2019

Noble-metal chalcogenides, dichalcogenides and phosphochalcogenides are an emerging class of two-dimensional materials. Their properties can be broadly tuned via quantum confinement (number of layers) and defect engineering, including metal-to-semiconductor transitions, magnetic ordering, and topological surface states. They possess various polytypes, often of similar formation energy, which can be assessed by selective synthesis approaches. They excel in mechanical, optical and chemical sensing applications, and feature long-term air- and moisture stability. In this review, we summarize the recent progress in the field of noble metal chalcogenides and phosphochalcogenides and highlight the structural complexity and its impact on applications.
Tautomer Database: A Comprehensive Resource for Tautomerism Analyses
Authors: Dhaked Devendra K. , Guasch Laura , Nicklaus Marc
Published: November 2019

We report a database of tautomeric structures that contains 2,819 tautomeric tuples extracted from 171 publications. Each tautomeric entry has been annotated with experimental conditions reported in the respective publication, plus bibliographic details, structural identifiers (e.g. NCI CADD identifiers FICTS, FICuS, uuuuu, and Standard InChI), and chemical information (e.g. SMILES, molecular weight). The majority of tautomeric tuples found were pairs, the remaining 10% were triples, quadruples, or quintuples, amounting to a total number of structures of 5,977. The types of tautomerism were mainly prototropic tautomerism (79%), followed by ring-chain (13%) and valence tautomerism (8%). The experimental conditions reported in the publications included about 50 pure solvents and 9 solvent-mixtures with 26 unique spectroscopic or non-spectroscopic methods. 1H and 13C NMR were the most frequently used methods. A total of 77 different tautomeric transform rules (SMIRKS) are covered by at least one example tuple in the database. This database is available as a spreadsheet for free download from https://cactus.nci.nih.gov/download/tautomer/.
Molecular Recognition Promotes Band Alignment in 3-D Covalent Organic Frameworks for Co-Crystalline Organic Photovoltaics
Authors: Cox Jordan M , Sadagopan Ananthan , Lopez Steven
Published: November 2019

Covalent organic frameworks (COFs) have emerged as versatile, functional materials comprised of low-cost molecular building blocks. The permanent porosity, long-range order, and high surface area of 3D-COFs permit co-crystallization with other materials driven by supramolecular interactions. We designed a new subphthalocyanine-based 3-D covalent organic framework (NEUCOF1) capable of forming co-crystals with fullerene (C60) via periodic ball-and-socket binding motifs. The high co-crystalline surface area and long-range order of NEUCOF1 eliminates the typical surface area vs. structural order trade-off in organic photovoltaics (OPVs). We used plane-wave density functional theory (PBE) to minimize NEUCOF1 and NEUCOF1–C60 co-crystals and determine their electronic band structures. Molecular dynamics (MD) simulations showed that NEUCOF1–C60 is likely to be stable up to 350 K. The band structures at 0 and 350 K suggest that charge transfer to the C60 acceptors is favorable and that directional charge transport is possible for these co-crystalline OPVs.

Published: November 2019

We describe a cyclic selenosulfide derivative of cysteine called SetCys that enables to perform protein chemical synthesis under redox-control.Native chemical ligation or SEA-mediated ligation with SetCys peptide segments proceeds in a traceless manner and involves the cleavage of a carbon-nitrogen bond in situ.The manuscript describes detailed mechanistic investigations of SetCys redox-switch and its application to the production of biologically active cyclic protein mimics of hepatocyte growth factor, the high-affinity ligand of MET tyrosine kinase receptor.
Defect-Mediated Conductivity Enhancements in Na3-xPn1-xWxS4 (Pn = P, Sb) using Aliovalent Substitutions
Authors: Fuchs Till , Culver Sean , Till Paul , Zeier Wolfgang
Published: November 2019

The sodium-ion conducting family of Na3PnS4, with Pn = P, Sb, have gained interest for the use in solid-state batteries due to their high ionic conductivity. However, significant improvements to the conductivity have been hampered by the lack of aliovalent dopants that can introduce vacancies into the structure. Inspired by the need for vacancy introduction into Na3PnS4, the solid solutions with WS42- introduction are explored. The influence of the substitution with WS42- for PS43- and SbS43-, respectively, is monitored using a combination of X-ray diffraction, Raman and impedance spectroscopy. With increasing vacancy concentration improvements resulting in a very high ionic conductivity of 13 ± 3 mS·cm-1 for Na2.9P0.9W0.1S4 and 41 ± 8 mS·cm-1 for Na2.9Sb0.9W0.1S4 can be observed. This work acts as a stepping-stone towards further engineering of ionic conductors using vacancy-injection via aliovalent substituents.

Published: November 2019

A range of methods is available for the synthesize nanoparticles. However, these methods are associated with the production of undesirable byproducts which are quite hazardous and high costs. Thus a number of efforts are being made to develop novel cost-effective safe & reliable "green" procedures which caned produce desired nanoparticles. In this study, we caned successfully develop a green synthesis method for preparation of silver nanoparticles using Desmodium gangeticum leaf extract as reducing & capping agents. The method was found a quite effective inversion of silver ions to silver nanoparticles in a short interval of time. The developed nanoparticles exhibited Surface plasmon resonance at around 500 nm. The particles are nearly spherical, and the size ranged between 16-64nm. The average size was noted to be around 40 nm. The nanoparticles were characterized for their morphology using UV-vis, TEM, FTIR analysis and FESEM. The developed method carries the advantage of the completion of the reaction in a short time. The crystalline nature of the synthesize nanoparticles was assessed & confirm by XRD & EDX Studies. From FTIR studies, it can be understood that the flavonoids could be adsorbed on the metal surface by interaction with carbonyl groups. The process was carried out in the environment-friendly condition.

20. yüzyılın ilk çeyreğinde, Mısır’ın mutlak bağımsızlığına gittiği düşünülen bir yolda, geleceğe yönelik umutları pekiştirmek amacıyla eski Mısır’ın parlak tarihinin idealize edilmesiyle sonuçlanan bazı fikir akımları ortaya çıkmıştır. 19. Yüzyılın sonlarına doğru ortaya çıkan ve Mısır Milliyetçiliği ya da Mısırcılık düşüncesinin ilkelerini esas alan fakat bu anti-sömürgeci söyleme bir miktar hümanizm de ekleyen antik mirasçılardan bazıları, çeşitli gazetelerde kaleme aldıkları makalelerde kendilerini “Firavuncu” olarak nitelendirecek kadar ileri gitmişlerdir. Firavuncular, Kadim Mısır medeniyetini dünya medeniyetlerinin kaynağı olarak görmüş ve Mısır halkına görkemli geçmişiyle gurur duymasını salık vermişlerdir. Antik dönem Mısır’ın Mısırlılar tarafından yönetildiği yegane dönem olarak idealize edilmiş ve modern Mısırlılar yüksek bir medeniyetin mirasını devralmış bir halk olarak nitelendirilmişlerdir. Ülkenin Firavunlar döneminde bilim ve sanat alanlarında kat ettiği mesafe, Ortaçağ Mısır’ının “sin(diril)mişliği” ile karşılaştırılmış ve yeniden “önce Mısırlı” olmak, Mısırlılara yegane çıkar yol olarak sunulmuştur. Mısır tarih yazıcılığındaki kadim köken vurgusu, 1930’ların ikinci yarısından itibaren popülerliğini yitirmiş ancak 1960’larda ve 1990’larda antik Mısır’a yönelik ilgilini artmasıyla 1920’lerdeki kadar yoğun olmasa da yeniden popülerlik kazanmıştır. Bu çalışmada, 20. Yüzyılda Mısır’ın seküler eğilimli entelektüelleri arasında geniş biçimde işlenen kadim köken temasının nasıl geliştiği, hangi tarihî-kültürel dayanaklardan hareketle oluştuğu, Mısır’ın önde gelen aydınları tarafından gerek dönemin önemli basın organları gerekse telif eserlerde serdedilen görüşleri, kadim köken temasının Mısır tarih, kültür ve edebiyatına yönelik ne tür okumalara temel teşkil ettiği gibi hususlar irdelenmeye çalışılmıştır.
Radial greed algorithm with rectified chromaticity for anchorless region proposal applied in aerial surveillance
Authors: Ocampo Anton Louise Pernez De , Dadios Elmer
Published: November 2019

In aerial images, human figures are often rendered at low resolution and in relatively small sizes compared to other objects in the scene, or resemble likelihood to other non-human objects. The localization of trust regions for possible containment of the human figure becomes difficult and computationally exhaustive. The objective of this work is to develop an anchorless region proposal which can emphasize potential persons from other objects and the vegetative background in aerial images. Samples are taken from different angles, altitudes and environmental factors such as illumination. The original image is rendered in rectified color space to create a pseudo-segmented version where objects of close chromaticity are combined. The geometric features of segments formed are then calculated and subjected to Radial-Greed Algorithm where segments resembling human figures are selected as the proposed regions for classification. The proposed method achieved 96.76% less computational cost against brute sliding window method and hit rate of 95.96%. In addition, the proposed method achieved 98.32 % confidence level that it can hit target proposals at least 92% every time.
INTELLIGENT SYSTEM FOR AUTOMATIC CLASSIFICATION OF FRUIT DEFECT USING FASTER REGION-BASED CONVOLUTIONAL NEURAL NETWORK (FASTER R-CNN)
Authors: Basri Hasan , Syarif Iwan , Sukaridhoto Sritrusta , Falah Muhammad Fajrul
Published: November 2019

In 2018, the Indonesian fruit exports increased by 24% from the previous year. The surge in demand for tropical fruits from non-tropical countries is one of the contributing factors for this trend. Some of these countries have strict quality requirements – the poor level quality control of fruit is an obstacle in achieving greater export yield. This is because some exporters still use manual sorting processes performed by workers, hence the quality standard varies depending on the individual perception of the workers. Therefore, we need an intelligent system that is capable of automatic sorting according to the standard set. In this research, we propose a system that can classify fruit defects automatically. Faster R-CNN (FRCNN) architecture proposed as a solution to detect the level of defect on the surface of the fruit. There are three types of fruit that we research, its mangoes (sweet fragrant), lime, and pitaya fruit. Each fruit divided into three categories (i) Super, (ii) middle, (iii) and fruit defects. We exploit join detection and video tracking to calculate and determine the quality fruit in real-time. The datasets are taken in the field, then trained using the FRCNN Framework using the Tensorflow platform. We demonstrated that this system can classify fruit with an accuracy level of 88% (mango), 83% (lime), and 99% (pitaya), with an average computation cost of 0.0131 m/s. We can track and calculate fruit sequentially without using additional sensors and check the defect rate on fruit using the video streaming camera more accurately and with greater ease.

Clinical Evidence of Lyme Disease in Dogs and Disease Awareness Among Students and Veterinarians in Veracruz, Mexico
Authors: Boria-Gamboa Blanca Paola , Villagómez-Cortés José Alfredo , Martínez-Herrera David Itzcoatl
Published: November 2019

Background: Lyme disease is a relatively new and zoonotic canine pathology mostly unknown by people involved in the management and care of dogs.  Objective: to assess the knowledge about Lyme disease by veterinarians and veterinary students in Veracruz, Mexico. Methodology: three questionnaires were designed and applied to 290 individuals (40 small animal veterinarians, 50 in other professional practice and 200 veterinary students). Results and discussion: in general, the three groups were unaware about the disease, although there is a high interest in learning about this problem. Graduates from seven universities included in this study stated that Lyme disease was not part of the veterinary curriculum in their schools. Five clinical cases suggestive of Lyme disease occurring in dogs in the area were detected at the time of this research. Conclusion: although the presence of the agent causing Lyme disease has not been demonstrated in the studied area due to the lack of laboratory support and the apparent absence of the vector, it cannot be ruled out; furthermore, it is important that veterinary practitioners and student alike be aware of the potential presence of Lyme disease, paying particular attention to differential diagnosis when resembling clinical signs are observed.
Mathematical modeling of heat transfer in a closed two- phase thermosyphon
Authors: Maksimov V. I. , Nurpeiis A. Е.
Published: November 2019

We suggested a new approach for describing heat transfer in thermosyphons and determining the characteristic temperatures. The processes of thermogravitation convection in the coolant layer at the lower cap, phase transitions in the evaporation zone, heat transfer as a result of conduction in the lower cap are described at the problem statement. The main assumption, which was used during the problem formulation, is that the characteristic times of steam motion through the thermosyphon channel are much less than the characteristic times of thermal conductivity and free convection in the coolant layer at the lower cap of the thermosyphon. For this reason, the processes of steam motion in the thermosyphon channel, the condensate film on the upper cap and the vertical walls were not considered. The problem solution domain is a thermosyphon through which heat is removed from the energy-saturated equipment. The ranges of heat flow changes were chosen based on experimental data. The geometric parameters of thermosyphon and the fill factors were chosen the same as in the experiments (height is 161 mm, diameter is 42 mm, wall thickness is 1.5 mm, ε=4-16%) for subsequent comparison of numerical simulation results and experimental data. In the numerical analysis it was assumed that the thermophysical properties of thermosyphon and coolant caps do not depend on temperature; laminar flow regime was considered. The dimensionless equations of vortex, Poisson and energy transfer for the liquid coolant under natural convection and the equations of thermal conductivity for the lower cap wall are solved by the method of finite differences. Numerical simulation results showed the relationship between the characteristic temperatures and the heat flow supplied to the bottom cap of thermosyphon. The results of the theoretical analysis are in satisfactory agreement with the known experimental data.
Regarding the application limitations of the Carnot, s theorem
Authors: Kiselev V. G.
Published: November 2019

The purpose of this article is to perform a comparative study of a reversible heat engine with an ideal or real gas as a working fluid and to determine the change in its efficiency depending on the thermodynamic characteristics of the working fluid. The main research method is the method of thermodynamic potentials, based primarily on the analysis of changes in the free and internal energy of an ideal and real gas in a cyclic process. The theory of thermodynamic potentials is used to consider the Carnot quasistatic heat engine. A comparative analysis of its operation is carried out, for a cycle with both an ideal and a real gas as a working fluid. The possibility of analyzing cyclic processes occurring in heat engines using the method of thermodynamic potentials has been identified and substantiated. The study has shown that the existing formulation of the Carnot’s theorem is valid only for ideal gas as a working fluid. Based on the work carried out, the Carnot’s theorem in the general case can be formulated, for example, as follows: the efficiency of the heat engine ηr, when it operates at the reversible Carnot cycle with real gas as a working fluid, is determined by the following expression:

hr= 1 - TB /TA + ε,

where TA and TB are the temperatures of the upper and lower isotherms of the Carnot cycle, respectively; ε is the correction term (positive or negative), depending on the thermodynamic properties of a real gas, which tends to zero as the properties of a real gas approach the properties of an ideal gas.
Supersonic flow of two-phase gas- droplet flows in nozzles
Authors: Sharapov A. I. , Chernykh A. A. , Peshkova A. V.
Published: November 2019

For practical applications, the description of processes occurring during the flow of two-phase gas-liquid mixtures requires a simple physical and mathematical model that describes the behavior of a two-phase medium in the entire range of phase concentrations changes and in a wide range of pressure changes. Problems of this kind arise in various branches of industry and technology. In the space industry, one often has to deal with the movement of various gases in rocket nozzles, consider the combustion, condensation of various vapors on the nozzle walls and their further impact on the velocity sublayer at the nozzle wall. The large acoustic effect arising from the engines affects the gas-liquid mixture in the nozzles of rocket engines. In the metal industry, metal cooling occurs with the help of nozzles in which the emulsion mixture is supplied under high overpressure. But this is only a short list of applied issues in which one has to deal with a problem of this type. The paper presents the results and directions of study of the problems of two-phase dispersed gas-droplet flows in the nozzles. The main methods of investigation of two- phase heterogeneous flows are described. The main characteristics of heterogeneous two-phase flows in the nozzles, which were confirmed by experimental results, are presented. The calculation of the air-droplet flow in the Laval nozzle is given. The technique, which is based on integral energy equations for two-phase dispersed flows, is described. The main problems and questions concerning the further description and studying of two-component flows are stated.

Sedangkan qa`if, adalah orang yangmempunyai keahlian khusus melihat orang lain dalam menghubungkan, menetukan nasabberdasarkan tanda-tanda dan kemiripan antara pihak yang diteliti. Menurut asy-Syafi`i, jasa qa`ifdalam menetapkan nasab seseorang dapat diterima sebagai ketetapan hukum. Oleh sebab itu, jikaditemukan persengketaan nasab dimana tidak ada bukti lain atau para pihak sama-sama memilikibukti yang kuat, maka persoalan itu diselesaikan dengan penelitian qa`if. Dalam mendukungpendapatnya, mazhab asy-Syafi`i beralasan dengan hadits Nabi Muhammad saw.dan atsar parasahabatnya. Oleh sebab itu praktik qiyafah diyakini memiliki justifikasi syariah. Genetika adalahsalah satu cabang dari ilmu biologi yang membahas tentang sifat keturunan yang diwariskan sertavariasi yang mungkin timbul di dalamnya. Praktik qiyafah maupun genetika sama-sama bertujuanuntuk meneliti sifat keturunan yang diturunkan secara turun temurun. Dilihat dari kesamaan fungsidan tujuan ini, maka qiyafah memiliki relevansi dengan ilmu genetika dalam menetapkan nasabseseorang.

Konstruksi Konflik dan Bina-Damai dalam Keberagaman Masyarakat Jawa
Authors: Sahfutra Suryo Adi
Published: November 2019

Agama dalam perspektif sosiologis sering muncul dalam dua wajah ganda, yaitu sebagai sumber konflik sekaligus sumber bina-damai. Faktanya, sulit dihindari bahwa adanya pemahaman yang menguatkan eskalasi konflik bersumber dari pemahaman ajaran agama, begitu juga sebaliknya proses bina-damai. Dalam konstruksi masyarakat Jawa, konflik dan bina-damai juga memiliki kekuatan dan kelemahannya masing-masing. Setidaknya dalam riset ini ditemukan bahwa masyarakat Jawa lebih memilih hidup rukun daripada konflik. Watak yang demikian mendominasi alam berpikir masyarakat Jawa. Oleh karena itu, bangunan tentang kedamaian mewujud tidak hanya dengan manusia melainkan juga dengan alam. Banyaknya prosesi ritualistik yang dibangun dalam sistem budaya menunjukkan bahwa orang Jawa senantiasa ingin berdamai dengan semua makhluk yang ada di alam raya.Kata kunci: Konflik, bina-damai, masyarakat Jawa, integrasi.

Information safety plays an important role in modern technologies. A stream encryption is one of the common means for information safety support. The sequences with pseudo-random characteristics are often required in the algorithms of stream enciphering. Random systems are recently used as a source of pseudo-random numbers with desired statistical properties. A small length of a sequence period is one of the known problems of the generators of pseudo-random numbers based on chaos realized with a small length of a digit grid. The disturbance of a path or a parameter of random system nonlinearity is one of possible solutions of a short period problem. In this paper there is considered a new approach to the increase of a period length through the change of a symmetry factor in the random model of a memristive circuit. The approach offered is based on switching two values of the symmetry factor in accordance with the output of a shear register with the linear feedback. To confirm the effectiveness of the disturbance circuit described the lengths of a period for the disturbed and original model of the memristive system are estimated. The properties of the output sequences caused by a generator on the basis of the model with controlled symmetry are confirmed by the results of the correlation analysis and NIST statistical testing. The results obtained can be used in cryptographic applications and also at the designing of safe communication systems.
ANATOMY OF THE CLADODES AND ECOLOGICAL ADAPTATION IN OPUNTIA (CACTACEAE) FROM THE PROVINCE OF BUENOS AIRES (ARGENTINA)
Authors: Arambarri Ana Maria , PERROTTA Vanesa Georgina
Published: November 2019

In this paper we examine the cladodes anatomy of Opuntia arechavaletae, O. aurantiaca, O. bonaerensis, O. elata, O. ficus-indica, O. megapotamica, O. penicilligera, O. sulphurea var. pampeana, and O. ventanensis that grows in the province of Buenos Aires, Argentina. The aim of this study was to establish diagnostic features in order to deepen knowledge of ability of adaptation to the environmental. Fresh and herbarium samples were prepared according to usual methods for light microscope. Histochemical techniques were performed to identify starch, mucilage and oxalate salts. The main traits found were: epidermis smooth and uniseriate, covered by a thin cuticle and epicuticular waxes; large stomata in low density, located at level with a deep substomatal chamber; a multilayered collenchyma including crystal layer; water storage parenchyma, and in vascular bundles a special water-storage cell type, resistant to collapse, and perhaps having some water transfer function  we named ‘intermediate cells’ which form masses in the xylem of  O. megapotamica, O. penicilligera, O. sulphurea var. pampeana, and O. ventanensis, which grows in xeric, saline and stone soils.

Unreported off-target integration of beta-lactamase from plasmid in gene-edited hornless cows
Authors: Chakraborty Sandeep
Published: November 2019

Concerns about the unintended effects of gene-editing is not new. Kim, et al, 2014 warned about ”unwanted integration of DNA segments derived from plasmids encoding Cas9 and guide RNA at both on- target and off-target sites”. Thus, there was nothing unexpected when in 2019 a FDA-authored pre-print reported template plasmid integration in the 2016 TALEN-edited hornless cows (Accid:PRJNA316122). Soon, yet another paper confirmed this on-target integration (Accid:PRJNA494431), and also reported that 4 out of 6 calves sired by one of the cow have inherited this plasmid in the targeted site on chromosome 1. However, this paper failed to report another definite off-target integration (in chromosome 14) of the beta-lactamase from the plasmid. Sequencing fragments, and then, samples the genome in any single pass, with the hope with enough passes the full genome would have been covered. For a roughly 3GB genome (as the bovine genome), 10-15 passes is not enough. In fact a read that is completely plasmid (and there are many) could be an integration anywhere. Thus, there might remain other integrations of the plasmid that are unobserved.

The world’s energy system is still dominated by fossil fuels. While there is a rapid reduction in the cost of renewable energy and the environmental costs of continued carbon dioxide emissions from fossil fuel recovery and use are well understood, current economic, infrastructure and political constraints sustain the fossil fuel enterprise as a dominant component of the energy system. Though routes to decarbonizing fossil fuel use, such as carbon capture and storage, have been proposed and have been demonstrated at commercial scale, current CCS CO2 storage quantities are very small and no large-scale practical route to providing fossil fuel energy, without the CO2 emissions attendant with fuel production and use has been proposed. Here we look at some of the boundary conditions and possible routes to production of emissions free energy from fossil fuels, and specifically petroleum reservoirs. Focusing on the production of electrical power we look at possible applications of microbially mediated hydrocarbon oxidation, coupled to a range of energy harvesting strategies, to the provision of electrical power at surface at a range of scales suitable for grid power provision, powering upstream oilfield facilities or for powering in situ sensing and exploration systems. We also ask the question, even if practical, would direct production of electrical power from oil and gas fields be a politically and economically sensible strategy as part of the energy transition away from traditional fossil fuel use.
Exploring Environmental Kuznets Curves of Kitakyushu: 50-year Time-series Data of the OECD SDGs Pilot City

Can green growth policies help protect the environment while keeping the industry growing and infrastructure expanding? The City of Kitakyushu, Japan, has actively implemented eco-friendly policies since 1967 and recently inspired the pursuit of sustainable development around the world, especially in the Global South region. However, empirical studies on the effects of green growth policies are still lacking. This study explores the relationship between road infrastructure development and average industrial firm size with air pollution in the city through the Environmental Kuznets Curve (EKC) hypothesis. Auto-Regressive Distributed Lag (ARDL) and Non-linear Auto-Regressive Distributed Lag (NARDL) methods were applied on nearly 50-years’ time series data, from 1967 to 2015. The results show that the shape of the EKC of industrial growth, measured by average firm size, depends on the type of air pollution: inverted N-shaped relationships with NO2 and CO, and the U-shaped relationships with falling dust particle and Ox. Regarding infrastructure development, on the one hand, our analysis shows a positive effect of road construction on alleviating the amount of falling dust and CO concentration. On the other hand, the emissions of NO2 and Ox are shown to rise when plotted against road construction. The decline of CO emission, when plotted against both industrial growth and road development, indicates that the ruthlessness of the local government in pursuing green growth policies is effective in this case. However, the story is not straightforward when it comes to other air pollutants, which hint at limits in the current policies. The case of Kitakyushu illustrates the complex dynamics of the interaction among policy, industry, infrastructure, and air pollution. It can serve as an important reference point for other cities in the Global South when policies are formed, and progress is measured in the pursuit of a green economy. Finally, as an OECD SDGs pilot city and the leading Asian green-growth city, policymakers in Kitakyushu city are recommended to revise the data policy to enhance the findability and interoperability of data as well as to invest in the application of big data.
Hubungan Demokrasi Pancasila dengan Gotong Royong
Authors: agustyana vivi
Published: November 2019

Di zaman modern seperti sekarang ini banyak sekali masyarakat yang menghilangkan rasa semangat ke gotong royongan. Di Indonesia sendiri sangat mengedepankan nilai-nilai Demokrasi pancasila yaitu, demokrasi ketuhanan yang maha esa, demokrasi kemanusiaan yang adil dan beradab, demokrasi persatuan Indonesia, demokrasi kerakyatan yang di pimpin oleh hikmat kebijaksanaan dalam permusyawaratan perwakilan dan demokrasi keadilan social bagi seluruh rakyat Indonesia. Maka dari itu gotong royong harus di tanamkan agar mencapai tujuan yang di inginkan bersama dan menciptakan masyarakat yang sejahtera. Gotong royong di negara dengan adanya negatif politik ini sangatlah sulit direalisasikan dikarenakan negara tidak melakukanya untuk membela rakyat sehingga rakyat merasa kurang percaya dengan politik di Indonesia ini. Indonesia sudah mengalami ekonomi dan politik yang kacau karena menurut saya mungkin kepemimpinan politik belum menjalani prinsip prinsip yang sudah ditetapkan. Karena menurut saya kepemimpinan ini tidak dikontrol dengan baik sehingga banyak terjadi permasalahan di Indonesia saat ini. Kondisi politik yang sangat memprihatinkan dan sedang berada di titik terendah, sudah tidak sempat memikirkan kegiatan gotong royong yang dulu sangat di junjung tinggi sebagai ideologi masyarakat. Pemerintah pun mungkin sudah tidak memikirkan jiwa sosial dan lebih mementingkan ego politik. Dan tidak ada kesantunan dalam berpolitik, semua tidak diselesaikan secara musyawarah mufakat lagi, seakan-akan kebiasaan bangsa Indonesia dahulu telah menurun dan lama-lama akan hilang. Maka dari itu perlu adanya kesadaran dari semua masyarakat Indonesia dalam merealisasikannya yaitu dengan musyawarah demi tujuan bersama menciptakan Indonesia yang sejahtera dengan mengedepankan nilai-nilai demokrasi pancasila.
