Building a System Dynamics Model to Support Water Management: A Case Study of the Semiarid Region in the Brazilian Northeast
Authors: Correia de Araujo Wanderbeg , Oliveira Esquerre Karla , Sahin Oz
Published: November 2019

In recent centuries, water consumption rates have more than doubled and the population growth rate is rising constantly. As a result, water scarcity is now one of the main problems to be faced, mainly in semiarid regions. In light of such a dilemma, this study aims to develop a system dynamics model in order to evaluate the water system in the semiarid region of the state of Paraíba—located in the Brazilian Northeast—and it focus on the following two issues: (1) measures that could have been taken with respect to the recent water crisis (2012–2017); (2) simulating water availability up to 2025. It was observed that, despite the options of in-demand management tools being efficient solutions for water scarcity in the short term (e.g., the influence of scarcity-based tariffs in reducing water use), such tools would not suffice in a context of severe drought within a water-providing system that depends heavily on rainfall. However, certain policies involving water-supply management (e.g., wastewater reuse and inter-basin water transfer) are very effective in maintaining water supply and avoiding a water collapse in the region. Furthermore, employing the Monte Carlo approach in simulating the system dynamic proved that the water supply is sensitive to scarcity-based tariffs, wastewater reuse, and inter-basin water transfer. An important advancement in this study was the simulation of a methodology for pricing that encourages rational use of water-based on its scarcity, which in turn increases revenue and investment in other water-management strategies.
Experimental Study on the Permeability Characteristic of Fused Quartz Sand and Mixed Oil as a Transparent Soil
Authors: Huang Bo , Guo Chang , Tang Yao , Guo Jiachen , Cao Linfeng
Published: November 2019

An accurate estimation of soil permeability is essential in geotechnical engineering. Transparent soil provides a promising experimental material to visualize pore-scale fluid flow, although the permeability characteristic of transparent soil remains unclear. As a result of the replacement of the fluid and solid phase, the permeability coefficient of transparent soil is usually several times or even more than ten times smaller than that of natural soil with the same particle size distribution and porosity. Fused quartz sand is used as the solid phase in this proposed transparent soil, which exhibits a similar mechanical behavior but different permeability to those of natural sand. Due to its low cost and eco-friendly characteristic, a mixture of mineral oil and aliphatic hydrocarbon is proposed as the liquid phase, which can achieve the same refractive index as the fused quartz sand after calculating the material proportion. Through a series of laboratory tests, the permeability of the transparent soil is obtained; the permeability is affected by the fluid dynamic viscosity, fluid density, particle size, particle size distribution, void ratio, and pore morphology. A hierarchical approach is introduced to quantitatively evaluate the effect of the particle shape on the permeability. Based on the experimental results, a modified Kozeny–Carman model is proposed for the prediction of transparent soil permeability, which can guide the preparation of transparent soil samples in further experimental studies.

This paper describes a large-scale experiment designed to examine if reinstating natural processes in the coastal dune systems of Southwest France can be a relevant nature-based adaptation in chronically eroding sectors and a nature-based solution against coastal hazards, by maintaining the coastal dune ecological corridor. An experiment started in late 2017 on a 4-km-long stretch of coast at Truc Vert, where experimental notches were excavated and intensively monitored in the incipient and established foredunes. Preliminary results indicate that most of the excavated notches did not develop into blowout. Only the larger elongated notches subsequently excavated in the established foredune in 2018 showed evidence of development, acting as an effective conduit for aeolian landward transport into the dunes. All notches were found to have a statistically significant impact on vegetation dynamics downwind, even those that did not develop. The area of bare sand landward and within the elongated notches notably increased implying a loss of vegetation cover during this first stage of development. Observations of a nearby coastal dune system that has been in free evolution over the last 40 years also indicate that, although the dune migrated inland by more than 100 m, it is now mostly made of bare sand. Further work is required to explore if and how dunes maintained as dynamic systems can become an efficient nature-based solution along this eroding coastline.
Acuerdo Mercosur-Unión Europea: Sombras y Ausencia de la solución de controversias inversor-Estado
Authors: Bas Magdalena
Published: November 2019

El Acuerdo Mercosur-Unión Europea es un hito en un momento de desglobalización y fuerte crisis del multilateralismo. Sin embargo, el texto no incluye los tradicionales mecanismos de arbitraje inversor- Estado ni el nuevo sistema de tribunales de inversiones que la Unión está negociando para sus acuerdos bilaterales. Este documento indaga en las posiciones que ambas partes tienen con respecto al régimen de solución de controversias inversor-Estado y en los motivos que sostienen esas posiciones (las “som- bras” mercosurianas y europeas). En particular, se destaca la posición de Brasil como actor externo al régimen y las consecuencias para los miembros del Mercosur de los casos que involucran cuestiones de derechos humanos. Desde la Unión Europea, su situación interna apunta a una dualidad: el rechazo de los arbitrajes intracomunitarios frente a la aceptación de los mecanismos incluidos en tratados con ter- ceros Estados (sea el arbitraje tradicional o su propuesta de un sistema de tribunales de inversiones).

Published: November 2019

INTRODUÇÃO: A impacção do incisivo central superior é uma condição desafiadora para os cirurgiões-dentistas e necessita, geralmente, de uma abordagem multidisciplinar. A não irrupção deste dente pode ocorrer devido à falta de espaço na arcada dentária, às alterações de erupções dos dentes decíduos e/ou permanentes, à presença de dentes supranumerários ou lesões patológicas adjacentes, e ao denso revestimento ósseo ou excesso de tecido mole local. O planejamento adequado e tratamento precoce podem minimizar os desconfortos estéticos e funcionais do paciente, evitando interferências negativas em seu desenvolvimento biopsicossocial. OBJETIVO: Apresentar um caso clínico de tracionamento de incisivo central superior impactado com apoio em barra transpalatina modificada em paciente infantil. RELATO DE CASO: Paciente do gênero masculino, 13 anos de idade, em desconforto estético com o sorriso devido à retenção prolongada do incisivo decíduo. Nos exames de imagem, notou-se a impacção do incisivo permanente, além de uma imagem sugestiva de odontoma composto e agenesia dos incisivos laterais permanentes. No primeiro momento, foi realizado a exodontia do incisivo e canino decíduo e exérese do odontoma composto, aguardando-se a erupção espontânea do incisivo permanente. Diante da irrupção incompleta do incisivo permanente no período de 6 meses, optou-se pelo seu tracionamento por meio da colagem de um botão ortodôntico e utilização de amarrilhos apoiados em uma barra transpalatina modificada. RESULTADO: Paciente encontra-se com o incisivo permamente já erupcionado, aguardando correção ortodôntica para melhor alinhamento e nivelamento dentário. CONCLUSÃO: A barra transpalatina modificada é um importante aparato ortodôntico para o apoio do amarrilho durante o tracionamento do incisivo impactado em pacientes com impossibilidade do uso do aparelho ortodôntico fixo.

Authors: Teixeira Henrique Couto , Da Silva Dias Lavínia , Menão Tauane Larissa , Esteves de Oliveira Erick
Published: November 2019

Uma nova era no tratamento do câncer está surgindo com o uso de anticorpos capazes de inibir pontos de bloqueio do sistema imunológico, chamados de “inibidores de checkpoint”. Um novo conceito de “balas mágicas”, que no início do século passado foram imaginadas por Paul Ehrlich como capazes de atuar diretamente na destruição de alvos tumorais, é representado agora por anticorpos direcionadas contra moléculas que bloqueiam a atividade antitumoral do sistema imunológico, como o antígeno de linfócitos T citotóxicos-4 (CTLA-4) e a proteína-1 de morte celular programada (PD-1). Essas novas imunoterapias vêm revolucionando a forma de tratar diferentes tipos de câncer. Nesta revisão selecionamos estudos, sobre CTLA-4 e PD-1, seus ligantes em células apresentadoras de antígenos, assim como destacamos a importância da descoberta de antígenos tumorais e o papel do sistema imunológico na imunovigilância tumoral. Nesse estudo são discutidos aspectos relacionados aos efeitos de imunoterapias baseadas no uso de anticorpos monoclonais anti-CTLA-4 e anti-PD-1/ PD-L1, como o risco de serem estimuladas respostas ​​direcionadas a tecidos saudáveis e outros efeitos adversos, bem como o uso de terapias combinadas que podem contribuir para melhorar a eficiência do tratamento do câncer.
Le rapt de Denys d'Alexandrie et la chronologie de ses lettres festales
Authors: Tissot Yves
Published: November 2019

Yves Tissot : The kidnapping of Denys of Alexandria and the chronology of his festal letters.

In his Ecclesiastical History, Eusebius quotes two passages from the festal letters of Denys of Alexandria, where the latter relates being abducted to Taposyris by peasants. At first, he sets the event in the time of the persecution of Decius (VI 40, letter to Germanius), but later in the period of Valerian (VII 11, letter to Dometius and Didymus). The analysis of these passages shows that, contrary the communis opinio, the abduction happened under Valerian. This permits us to date the second letter to the year 259 and all of Denys' festal letters between that year and 262, thereby preserving them in the order in which they are mentioned by Eusebius.
La contextualisation : un concept théologique ?

Salah satu alat musik klasik yang hampir ditinggalkan atau jarang dimainkan adalah alat musik harpa. Seperti halnya di Indonesia alat musik harpa sudah sangat jarang dimainkan atau ditampilkan pada pergelaran alat musik. Agar alat musik harpa tidak dilupakan dan mudah diingat kembali, Maka telah diciptakan suatu alat musik harpa yang modern yang berbasis teknologi yang menggunakan laser sebagai pengganti dawai penghasil nadanya. Mikrokontroler ATMega8535 digunakan sebagai otak pengaturan alat ini. Sensor LDR merupakan indikator pengaktifan nada, dan sensor PING dijadikan sebagai pembagi tinggi dan rendahnya oktaf nada tersebut. Dimana dawai laser diputus di atas dan di bawah akan menghasilkan nada yang sama tetapi oktaf nya berbeda. ATMega8535 akan mengeluarkan output dengan frekuensi yang berbeda beda kemudian diteruskan kepada amplifier(penguat) dan speaker digunakan sebagai output akhir berupa bunyi nada. Hasil akhir yang di hasilkan laser harpa adalah suara degan frekuensi yang sesuai dengan nada-nada standar. Dengan pembuatan laser harpa ini telah menghasilkan generasi muda lebih terpacu dan inovatif dalam mengembangkan ilmu baik di bidang teknologi maupun di bidang seni.

Telah dilakukan studi eksperimental pengaruh pemberian bahan bakar hydrogen terhadap tingkat getaran (vibrasi) dan kebisingan (noise) dengan sistem dual fuel (campuran bahan bakar solar dengan hydrogen dari hasil produk reaksi kaleng bekas) pada engine stasioner, dan analisa voltase serta arus yang terjadi. Metode penelitian dilakukan dengan membandingkan tingkat getaran, kebisingan, voltase, dan arus yang dihasilkan antara system single fuel (bahan bakar solar) dengan system dual fuelÂ  sebagai variable bebas, sedangkan variasi beban sebagai variable tetap dari operasi engine tanpa beban (0 Watt) sampai dengan beban 2000 Watt (dengan interval 200 Watt).Â  Hasil analsisa data pengujian menunujkkan bahwa untuk tingkat getaran yang diukur pada base mesinÂ  terjadi perbedaanÂ  tingkat vibrasi dimana pada system dual fuel terjadi getaran rata-rata sebesar 1,75 mm (displacement) dan mengalami peningkatan getaran dibandingkan dengan system single fuel sebesar 1,57 mm, hal ini disebabkan oleh knocking yang terjadi diruang bakar engine, sedangkan getaran yang terbesar terjadi pada saat beban 200 watt system dual-fuel yaitu sebesar 2,78 mm.Untuk tingkat getaran yang terjadi pada mesin diesel dengan system dual-fuel menggunakanÂ  campuran bahan bakar solar dengan gas hydrogen mengalami kenaikan sebesar 0,18 mm pada saat pengukuran displacement dibandingkan dengan getaran mesin diesel system single-fuel bahan bakar solar, namun dari segi kebisingan mengalami penurunan sebesar 2,6 dB, hal ini disebabkan akibat penambahan hydrogen pada saluran udara masuk (air intake) mesin diesel, sehingga kandungan hydrogen akan mengurangi suara karena mesin kaya akan bahan bakar.

The anti-corrosion property of expired
Abacavir Sulfate drug on the mild steel (MS) in the 3 M HCl solution was
carried out with the help of weight loss, atomic absorption spectroscopy, Tafel
plot, impedance spectroscopy, and scanning electron microscopy studies. The
weight loss studies show that, protection property enhances with a rise in the
amounts of expired Abacavir Sulfate drug and the maximum of protection
efficiency observed at 0.4 g/L of expired Abacavir Sulfate drug. The
effect of four different amounts of expired Abacavir Sulfate drug on the
MS in the 3 M HCl solution was studied by atomic absorption spectroscopy
technique. Mixed MS corrosion inhibition property of expired
Abacavir Sulfate drug was confirmed by Tafel plot studies. Nyquist plot
studies show that, charge transfer resistance (R ct) values are directly
proportional to the expired Abacavir Sulfate drug. Scanning electron
microscopy results shows that, smooth MS surface in 3 M HCl solution is due to
the presence of 0. 4 mg/L of expired Abacavir Sulfate drug.

Published: November 2019

Designing and fabricating complementary metal-oxide
semiconductor (CMOS) based logic devices at nanoscale
faces serious issues like oxide thickness, thermal reliability, and energy
dissipation. Hence the industries are in search of new technologies which could
substitute the scaling down of CMOS circuits. Quantum-dot-cellular-automata
(QCA) is an imminent technology considered at nano-level with the
high speed of operation and lower power dissipation features. As the memory is
used in most of the electronic equipment for data storage purpose, designing a
RAM cell with a reduced number of QCA cells, and lower energy dissipation finds
wide applications in the electronics industry. This paper first proposes a
five input majority gate which may be utilized efficiently for designing single
layer QCA circuits. Then by using the invented gate, a coplanar RAM cell structure with Set and
Reset capability is devised. The structural
and energy dissipation analysis
of presented structures are estimated using QCADesigner
and QCAPro tools. The results prove that the disclosed RAM cell architecture
achieves 12.5% lower area, 18.26% lower
total energy dissipation, and 16.6% lower input to output delay than the best-reported design.
A Study on Hydrothermal Grown CdS Nanospheres: Effects of Cd/S Molar Ratio
Authors: YILMAZ Salih , TOMAKIN Murat , UNVERDI Ahmet , ABOGHALON Abdulaziz
Published: November 2019

The study reports the influences of altering
of Cd/S molar ratio on some physical properties of hydrothermal grown CdS
nanospheres. Cd/S molar ratios were chosen as 1:0.5, 1:1, 1:2, 1:3 and 1:4 in the stock
solution. X-ray diffraction (XRD) data showed the occurrence of nano-amorphous
CdS structure. Scanning electron microscopy (SEM) conclusions illustrated that
increasing Cd/S molar ratio up to 1:3 caused a growth in the sphere size
whereas further rising of Cd/S molar ratio led to smaller sphere size. The
presence of Cd and S atoms in CdS structure was approved by Energy dispersive
x-ray spectroscopy (EDS) analysis. Optimum transparency was found by Cd/S molar
ratio of 1:3. Band gap scores of CdS nanospheres were determined to be above
2.60 eV that was bigger than bulk CdS (2.42 eV) because of quantum confinement
effect. Photoluminescence (PL) results showed that a gradual decrease in each
peak was attained upon increasing Cd/S molar ratio, which could be due to the
formation non-radiative recombination phenomenon. Electrical data demonstrated
that CdS nanosphere having Cd/S molar ratio of 1:1 exhibited the best carrier
density (1.48´1015cm-3)
and resistivity (1.27´103
Ω.cm) values. Thus, it can be deduced
that Cd/S molar ratio of 1:3 was obtained to be optimum one since it possesses
both bigger sphere size and better transparency, facilitating the effective use
of CdS nanospheres in the solar cells.

Introduction. The experience of developing the economies of the developed countries of the world suggests that it is directly related to the evolution of transport and infrastructure. In most of countries, intelligent transport systems (ITS) are under investigation as one of the scientific directions of the symbiosis of the economy - technology – telematics, and considered as the most effective tool for solving transport problems. The efforts of international organizations, state representatives in the field of transport, scientists, entrepreneurs and the public are aimed at such key areas as: significant increase in both the safety of transport on all modes of transport and capacity grows of the transport system of the country.
Purpose. The goal of the article is to develop a single integrated approach to the definition of the term ITS and to provide a general classification system with details on the management objects.
Methods. To achieve the goal methods have been used based on the systems approach, management theory and decision-making theory. The system analysis has been used to determine the scientific task.
Results. In order to implement the tasks of transport management in terms of ITS, the system analysis of the field of research has been carried out in the article, including the systematization of the definition and the construction of a general classification system with details on the management objects. The analysis of the subject area of ITS usage has allowed establishing the main classes of the analyzed objects, to classify the tasks of monitoring characteristics, organization of management of transport flows and transportation process, information support for participants, organization of transport infrastructure management. Research of the literature sources allowed to form an integrated approach to the ITS classification system, which includes both systems introduced in the objects of transport infrastructure and in the management of transport flows. In the addition to the above, the main thing in the infrastructure objects is the terminal monitoring and management system, as well as the security management system.
Conclusion. ITS is a new type of transport management systems that are gradually replaced by automated control systems. They are focused on modeling various cases and forecasting of dangerous situations and be used for decision-making tool in the condition of great complexity and large amounts of data. ITC can be considered as an important component of the modern integrated approach to improving the efficiency of the functioning of the country's transport system by expanding their information infrastructure: automated data collection on state of the system in real time, modeling direct and indirect operational impact on the formation and change of transport flows.
